    ABSTRACT: This study was designed to evaluate the analgesic effect of wrist-ankle acupuncture (WAA) for patients with primary liver cancer (PLC) after transcatheter arterial chemoembolization (TACE). Sixty PLC patients with post-TACE visual analog pain intensity scores greater than 3 were divided equally into two groups receiving either WAA or oral morphine sulphate (MOR) for post-TACE pain. Pain intensity scores were reassessed at 1, 2, 4, and 6 h after analgesic intervention. Patients were also monitored for adverse reactions to analgesic treatment. Pain scores recorded when the patients first felt pain after TACE showed no statistical difference between the two groups (p > 0.05). WAA and MOR had indistinguishable degrees of pain relief 1, 2, and 4 h after analgesic intervention (p > 0.05). At 6 h after intervention, the WAA group experienced significantly greater pain relief than the MOR group (p < 0.05). Incidence of abdominal distension was lower in the WAA group than in the MOR group (p < 0.05). The results suggest that WAA not only had an analgesic effect equal to or greater than MOR in PLC patients with moderate to severe post-TACE pain, but also reduced the incidence of post-operative abdominal distention.

    ABSTRACT: Multidrug resistance (MDR) is a major obstacle to chemotherapy in patients with hepatocellular carcinoma (HCC). To overcome MDR and improve chemotherapeutic efficacy, novel reversal agents with higher efficacy and lower toxicity are urgently needed for HCC. The present study was designed to examine the potential reversal activity of bufalin, a toxic ligand isolated from the traditional Chinese medicine 'Chansu' and to elucidate the possible related mechanisms. A multidrug-resistant HCC cell line, BEL-7402/5-FU, was used as the cell model. The working concentration of bufalin as an effective reversal agent, and the cell viability in the reversal experiments were determined by MTT assay. The effects of bufalin at a non-cytotoxic dose on cell cycle distribution, apoptosis and drug efflux pump activity were measured by flow cytometry. Qualitative observation of apoptosis was also carried out by confocal microscopy. Furthermore, the effects of bufalin on the expression of potential genes involved in MDR of BEL-7402/5-FU cells, including thymidylate synthase (TS), P-glycoprotein (P-gp), multidrug resistance protein 1 (MRP1), B-cell lymphoma-extra large (Bcl-xL) and Bcl-2-associated X protein (Bax), were determined using real-time PCR and western blot analysis. The results showed that bufalin at a concentration of 1 nM enhanced the chemosensitivity of BEL-7402/5-FU cells to 5-FU with a reversal fold of 3.8 which was similar to that of 1 µM verapamil. Bufalin significantly arrested the cell cycle at the G0/G1 phase, induced apoptosis through an increase in the Bax/Bcl-xL ratio, inhibited drug efflux pump activity via downregulation of MRP1, and reduced the expression of TS in BEL-7402/5-FU cells. The present study revealed that bufalin effectively reversed MDR in BEL-7402/5-FU cells through multiple pathways. The combination of bufalin with cytotoxic drugs may serve as a promising strategy for the chemotherapy of HCC.

    ABSTRACT: BACKGROUND: Disease recurrence is a main challenge in treatment of hepatocellular carcinoma (HCC). There is no generally accepted method for preventing recurrence of HCC after resection. OBJECTIVE: To compare the efficacy of a traditional herbal medicine (THM) regimen and transarterial chemoembolization (TACE) in preventing recurrence in post-resection patients with small HCC. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a multicenter, open-label, randomized, controlled study, which was undertaken in five centers of China. A total of 379 patients who met the eligibility criteria and underwent randomization were enrolled in this trial. One hundred and eighty-eight patients were assigned to the THM group and received Cinobufacini injection and Jiedu Granule, and the other 191 patients were assigned to the TACE group and received one single course of TACE. MAIN OUTCOME MEASURES: Primary outcome measures were the annual recurrence rate and the time to recurrence. Incidence of adverse events was regarded as the secondary outcome measure. RESULTS: Among the 364 patients who were included in the intention-to-treat analysis, 67 patients of the THM group and 87 of the TACE group had recurrence, with a hazard ratio of 0.695 (P = 0.048). Median recurrence-free survival of the patients in the THM and TACE groups was 46.89 and 34.49 months, respectively. Recurrence rates at 1, 2 and 3 years were 17.7%, 33.0% and 43.5% for the THM group, and 28.8%, 42.5% and 54.0% for the TACE group, respectively (P = 0.026). Multivariate analysis indicated that the THM regimen had a big advantage for prolonging the recurrence-free survival. Adverse events were mild and abnormality of laboratory indices of the two groups were similar. CONCLUSION: In comparison with TACE therapy, the THM regimen was associated with diminished risk of recurrence of small-sized HCC after resection, with comparable adverse events. TRIAL REGISTRTION IDENTIFIER: This trial was registered in the Chinese Clinical Trial Registry with the identifier ChiCTR-TRC-07000033.

    ABSTRACT: To study the possible mechanism of Sisheng Decoction on spleen deficiency syndrome via the observation of general conditions, immunity and anti-stress function in Dahuang (Radix et Rhizoma Rhei Palmati)-induced mice model. Mice were randomized and grouped based on the body weight. The establishment of model and the treatment were done simultaneously. Except the mice in normal group, the decoction and the Dahuang powder were separately given in the morning and the afternoon for 14 d. The general condition of the mice, the rectal temperature, the time of burden swimming, the indexes of thymus and spleen and the interleukin-2 (IL-2) concentration in the serum were observed. The group treated with Sisheng Decoction showed better performance than that of the model group, including less stool, strong appetite and fast growth; the medium- and high-dose Sisheng Decoction increased the rectal temperature of mice. There was no statistical difference in the thymus and spleen indexes between the groups treated by Sisheng Decoction and the normal group (P>0.05). The thymus index in groups treated by sisheng Decoction was significantly elevated as compared with the model group (P<0.05). The medium- and high-dose Sisheng Decoction significantly improved the concentration of IL-2 and prolonged the time of burden swimming, as compared to the model group (P<0.05). The medium- and high-dose Sisheng Decoction is good at invigorating spleen and replenishing qi. One of the possible mechanisms may be related with the improvement of the immunity and anti-stress function of the body.

    ABSTRACT: To analyze the distribution of traditional Chinese medicine constitution types in elderly patients with insomnia. The epidemiological data were collected from communities in the Yangpu District, Shanghai via a cross-sectional field survey. The elderly participants were enrolled by using the Pittsburgh Sleep Quality Index (PSQI) scale and the TCM Constitution Questionnaire. (1)The distribution of imbalanced constitutions between the elderly with insomnia and normal subjects showed statistical difference (P<0.01) and the elderly with insomnia tend to be of imbalanced constitutions. Among these unbalanced constitutions, deficient constitutions were more frequent than others in the elderly with insomnia, and yang-deficiency and qi-deficiency occurred mostly in unbalanced and simple constitutions. (2) Blood-stasis and qi-stagnation constitutions were more frequent in females than in males among the elderly with insomnia. Frequency of deficiency constitutions in the elderly increased as the age increases. (3) The frequency of composite constitutions was higher than that of simple constitutions in elderly patients with insomnia (74.8%), among which qi-deficiency was more likely to be composite with other constitutions. Identification and classification of traditional Chinese medicine constitution types will provide further information for devising projects with systematic intervention for insomnia management.

    ABSTRACT: To investigate the therapeutic effects of Jiedu granules, a Chinese medicine (CM) compound, plus cinobufacini injection, which was extracted from skin of Bufo bufo gargarizans Cantor, to prevent the recurrence of hepatocellular carcinoma (HCC) after surgical resection. In this case-control trial, a total of 120 patients who stayed in Changhai Hospital were enrolled from December 2001 to December 2006. Sixty patients were treated with Jiedu granules plus cinobufacini injection to prevent tumor recurrence after operation (CM group) and 60 patients were treated with transcatheter arterial chemoembolization (TACE) after operation (TACE group). Progression-free survival (PFS) and overall survival (OS) rates were determined to evaluate the therapeutic effects of post-operative management of patients with HCC. PFS in the CM group was 18.07 months [95% confidence interval (CI): 12.49-23.65] and the 1-, 2-, 3-, 4- and 5-year PFS rates were 61%, 39%, 26%, 22% and 12%, respectively. PFS in the TACE group was 8.03 months (95% CI: 6.63-9.44) and the 1-, 2-, 3-, 4- and 5-year PFS rates were 34%, 11%, 7%, 2% and 0%, respectively. There was significant difference in survival rate between the two groups (P<0.01). The mean survival time (MST) of patients in the CM group was 49.53 months versus 39.90 months of the TACE group. The 1-, 2-, 3-, 4- and 5-year survival rates were 90%, 82%, 80%, 70% and 63%, respectively, in the CM group, and 79%, 70%, 60%, 60% and 36%, respectively, in the TACE group. There was significant difference in survival time between the two groups (P=0.045). Jiedu granules plus cinobufacini injection, a combination that is commonly used for post-operation management of HCC, can postpone tumor recurrence and metastasis, prolong the survival time and increase the survival rate of post-surgical patients with HCC. However, these findings need to be confirmed in a prospective, randomized controlled trial.

    ABSTRACT: To study the traditional Chinese medicine (TCM) syndrome distribution in patients with hepatitis B virus (HBV) infection in Qidong region of Jiangsu Province, China. A cross-sectional survey was performed. Subjects from Qidong of Jiangsu Province of China were screened among the locally enrolled residents by detecting hepatitis B surface antigen (HBsAg) from May 2007 to May 2011 and were assigned to HBsAg-negative cohort or HBsAg-positive cohort. Then, the subjects were diagnosed according to alanine aminotransferase, alpha-fetoprotein and B ultrasound. The syndrome of the subjects was determined using a TCM questionnaire consisting of signs and symptoms. A total of 5 908 subjects were enrolled in this survey, among whom, 4 718 were diagnosed with HbsAg infection (positive result of HbsAg detection) and 1 147 were negative. 143 subjects were excluded for not receiving the blood examination. The final diagnoses of the subjects were non-HBV infection (n=1128), HBV carrier (n=4019), chronic hepatitis B (n=225), posthepatitic cirrhosis (n=263) or liver cancer (n=111). The TCM syndrome differentiation results showed that there were differences in syndrome distribution between HBV-infected and non-HBV-infected patients. The main syndromes of the HBV-infected patients were qi deficiency, qi stagnation, blood stasis and dampness heat, related to the Zang of liver and spleen. The distribution principles of TCM syndrome among patients of HBV carrier, chronic hepatitis B and cirrhosis were similar. Moreover, with the progression of the patients' condition, the scores of syndromes increased, and the number of accompanying syndromes increased as well. The main syndromes of patients with liver cancer were blood stasis and excess heat, which was slightly different from that of the other HBV-infected patients. The TCM syndrome distribution in patients of HBV infection in Qidong region of Jiangsu Province shows regularity. The disorder is mainly due to qi stagnation and blood stasis and is also related to deficiency of healthy qi, especially deficiency of spleen qi.

    ABSTRACT: To extract the active component from the root of Actinidia valvata Dunn and to investigate the effects on hepatocellular carcinoma (HCC) cells in vitro. Total saponin was extracted from the root of A. valvata (TSAVD). HCC cells, such as BEL-7402, HepG2, PLC, SMMC-7721, MHCC-97-H, and MHCC-97-L, were treated with TSAVD in 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenytetrazolium bromide (MTT) assay. BEL-7402 and MHCC-97-H cells were also treated respectively with TSAVD at different concentrations for 24 h in wound healing and adhesion assays, and the effects of TSAVD on BEL-7402 and MHCC-97-H cells mobility and adhesion abilities were observed. Meanwhile, the effects of TSAVD on invasion and migration of BEL-7402 and MHCC-97-H cells were also investigated by transwell chamber in invasion and migration assays. TSAVD at 1.5 mg/mL inhibited BEL-7402 cell proliferation with inhibition ratios (IRs) of 61.08%, 74.12%, 84.55% at 24, 48, and 72 h, respectively. Meanwhile, TSAVD inhibited MHCC-97-H proliferation in a concentration-dependent manner from 1.5 to 0.5 mg/mL, with the IR of 36% at 1.5 mg/mL at 24 h. For SMMC-7721, PLC, and HepG2, the IR was lower than 30% at 1.5 mg/mL at 24 h. In the wound healing assay, mobility abilities of BEL-7402 and MHCC-97-H cells in TSAVD treated groups were significantly weaker than those of the control group. After pretreatment for 24 h with TSAVD, adhesion abilities were reduced in both MHCC-97-H and BEL-7402 cells, with IRs of 48.50%±4.86% and 49.85%±5.25% at 200 μg/mL. The IRs of MHCC-97-H and BEL-7402 cells in the migration assay were 49.13%±2.91% and 79.37%±0.09% at 200 μg/mL. In the invasion assay, IRs were 69.78%±4.88% and 82.48%±0.25% at 200 μg/mL. Of all HCC cells, the highest inhibition by TSAVD was seen for BEL-7402 proliferation. TSAVD could restrain adhesion, invasion, mobility, and migration abilities of BEL-7402 and MHCC-97-H cells in vitro.

    ABSTRACT: The root of Actinidia valvata dunn has been widely used in the treatment of hepatocellular carcinoma (HCC), proved to be beneficial for a longer and better life in China. In present work, total saponin from root of Actinidia valvata Dunn (TSAVD) was extracted, and its effects on hepatoma H22-based mouse in vivo were observed. Primarily transplanted hypodermal hepatoma H22-based mice were used to observe TSAVD effect on tumor growth. The microvessel density (MVD), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) are characterized factors of angiogenesis, which were compared between TSAVD-treated and control groups. Antimetastasis effect on experimental pulmonary metastasis hepatoma mice was also observed in the study. The results demonstrated that TSAVD can effectively inhibit HCC growth and metastasis in vivo, inhibit the formation of microvessel, downregulate expressions of VEGF and bFGF, and retrain angiogenesis of hepatoma 22 which could be one of the reasons.

    ABSTRACT: Purpose: The chemoresistance of human hepatocellular carcinoma (HCC) to cytotoxic drugs, especially intrinsic or acquired multidrug resistance (MDR), still remains a major challenge in the management of HCC. In the present study, possible mechanisms involved in MDR of HCC were identified using a 5-fluorouracil (5-FU) -resistant human HCC cell line. Methods: BEL-7402/5-FU cells were established through continuous culturing parental BEL-7402 cells, imitating the pattern of chemotherapy clinically. Growth curves and chemosensitivity to cytotoxic drugs were determined by MTT assay. Doubling times, colony formation and adherence rates were calculated after cell counting. Morphological alteration, karyotype morphology, and untrastructure were assessed under optical and electron microscopes. The distribution in the cell cycle and drug efflux pump activity were measured by flow cytometry. Furthermore, expression of potential genes involved in MDR of BEL-7402/5-FU cells were detected by immunocytochemistry. Results: Compared to its parental cells, BEL-7402/5-FU cells had a prolonged doubling time, a lower mitotic index, colony efficiency and adhesive ability, and a decreased drug efflux pump activity. The resistant cells tended to grow in clusters and apparent changes of ultrastructures occurred. BEL-7402/5-FU cells presented with an increased proportion in S and G2/M phases with a concomitant decrease in G0/G1 phase. The MDR phenotype of BEL-7402/5-FU might be partly attributed to increased drug efflux pump activity via multidrug resistance protein 1 (MRP1), overexpression of thymidylate synthase (TS), resistance to apoptosis by augmentation of the Bcl-xl/Bax ratio, and intracellular adhesion medicated by E-cadherin (E-cad). P-glycoprotein (P-gp) might play a limited role in the MDR of BEL-7402/5-FU. Conclusion: Increased activity or expression of MRP1, Bcl-xl, TS, and E-cad appear to be involved in the MDR mechanism of BEL-7402/5-FU.

    ABSTRACT: To observe effects of cold- and hot-property herbs and effects of hot and cold constitutions on the tumor growth of tumor bearing rats, and to observe the effect of Cinobufacini Injection (CI) on the tumor growth of tumor bearing rats of different constitutions. Eighty healthy male Wistar rats were randomly divided into eight groups, i.e., the tumor bearing control group, the tumor bearing heat syndrome group, the tumor bearing cold syndrome group, the heat syndrome tumor bearing group, the cold syndrome tumor bearing group, the tumor bearing CI group, the heat syndrome tumor bearing CI group, and the cold syndrome tumor bearing CI group, respectively. The weight and volume of rats' subcutaneous tumor were measured 14 days after tumor innoculation. The weight and volume of tumor in the heat syndrome tumor bearing CI group [(3.55 +/- 1.12) g, (2864.44 +/- 1430.51) mm3] and the tumor bearing CI group [(4.29 +/- 1.14) g, (3397.19 +/- 1701.13) mm3] were significantly lower than those of the tumor bearing control group [(6.01 +/- 2.45) g, (6218.91 +/- 3837.64) mm3] and the cold syndrome tumor bearing CI group [(6.90 +/- 1.57) g, (6168.42 +/- 2457.03) mm3], showing statistical difference (P<0.05). There was insignificant difference among other groups. CI showed better tumor inhibition effects on tumor bearing rats of heat syndrome constitution, which indicated CI was of cold property. It might be possibly used in tumor bearing rats of heat syndrome constitution.

    ABSTRACT: To explore the protective effects of Huqi extractum, a compound Chinese herbal medicine, on salivary glands against radiation in Wistar rats. One hundred Wistar rats were randomly divided into sham-exposure group, untreated group, and low-, medium- and high-dose Huqi groups. Local irradiation of 60Co gamma-rays with a single dose of 15 Gy was applied to the salivary glands of the Wistar rats except the sham-exposure group. After 3- and 40-day treatment, saliva was collected. Colorimetric method, iodine-amylase colorimetric method and enzyme-linked immunosorbent assay were used to detect concentrations of sodium (Na+), potassium (K+) and secretory immunoglobulin A (sIgA) and activity of salivary amylase. Pathological changes of salivary gland tissues were observed by hematoxylin-eosin straining. After 3-day administration, radiation-induced salivary gland injuries were obvious and prevalent in irradiated rats. Comparing with the sham-exposure group, saliva concentration of sIgA and body weight were reduced in other irradiated groups, except those in the high-dose Huqi group, while salivary amylase level was increased. At 3-day phase, pathologic changes of the salivary glands were featured as swelling acinus plasm and vacuolation. At 40-day phase, atrophy of gland cells was dominant. After 40-day administration, there were no significant differences between the high-dose Huqi group and sham-exposure group in sIgA and amylase levels and body weight, and according to the histological examination, no significant difference was revealed under the optical microscope. Chinese herbal medicine is helpful for the recovery of the salivary glands from the radiation injury, morphologically and functionally in rats.

    ABSTRACT: Metastasis is one of the specificities of late stage tumor and also a lethal factor often encountered. The study of tumor metastasis has important meaning for prolonging patients' survival and elevating their quality of life, but no really ideal prevention and treatment method has been found so far. Recent researches showed that tumor metastasis is correlated with platelet aggregation and blood hyperviscosity manner. Therefore, the early application of surgery, radiotherapy, chemotherapy and biological therapies, in combination with Chinese medicine therapy for activating blood circulation and removing stasis (ABCRS) may be, after all, an effective approach. ABCRS therapy is an important therapy of Chinese medicine, which, composed of several methods like smoothening blood flow in vessels, promoting blood circulation and dispersing stagnant blood, could influence tumor metastasis to different extents, and could coordinate with some other Chinese medicine therapeutic methods like supplementing qi, promoting qi, clearing heat, removing toxic substances, warming meridian, dispelling wind, eliminating dampness, nourishing yin, dissolving sputum, relieving stagnancy, emptying viscerals, etc. The effect and acting mechanism of ABCRS on tumor metastasis is summarized in this paper and its bi-directional regulatory effects discussed as well.

    ABSTRACT: Transcatheter arterial chemoembolization (TACE) is the most widely used primary treatment for unresectable hepatocellular carcinoma (HCC) because of its survival benefit, although its clinical effect is still far from satisfactory. In China, there has been a long history of using traditional Chinese medicine in the treatment of liver cancer and other malignancies. In this study, the authors evaluated the effect of combined therapy with TACE and JDF granule preparation (a traditional Chinese herbal medicine formula) in the treatment of patients with unresectable HCC on survival. Clinical data, including baseline, performance status change, and survival time of 165 patients with unresectable HCC seen between January 2002 and December 2007 were retrospectively analyzed. Among the 165 patients, 80 patients (study group) received combined therapy consisting of TACE and a long-term maintenance treatment with oral JDF granule preparation, and 85 patients (control group) received TACE alone. The survival rate of both groups was calculated by the Kaplan-Meier method. Factors possibly affecting survival were assessed by multivariate analysis in the Cox proportional hazard model. The median overall survival was 9.2 months (95% confidence interval [95% CI], 6.94-1.46) in the study group versus 5.87 months (95% CI, 4.21-7.52) in the control group. In the study group (TACE + JDF), 1-year, 2-year, and 3-year survival rates were 41.2%, 18.4%, and 9.6%, respectively. The Cox regression analysis revealed the therapy model to be an independent predictor of patient prognosis. Current study data demonstrated that TACE combined with JDF granule preparation could improve the prognosis of patients. TACE combined with JDF granule preparation may prolong survival of patients with unresectable HCC.

    ABSTRACT: Transarterial chemoembolization (TACE) is the most widely used primary treatment for unresectable hepatocellular carcinoma (HCC) due to its survival benefit, though its clinical effect is still far from satisfactory. Jiedufang (JDF) granule preparation is a commonly used Chinese herbal medicine formula for HCC. The aim of this study was to evaluate the effect of combined therapy with TACE and JDF granule preparation in treatment of unresectable HCC on survival. A retrospective study of TACE was performed in 165 patients with unresectable HCC who were admitted between January 2002 and December 2007 in Changhai Hospital, Shanghai, China. Of the 165 patients, 80 patients (study group) received combined therapy consisting of TACE and a long-term maintenance treatment with oral JDF granule preparation, and the remaining 85 patients (control group) received TACE alone. The survival rates of both groups were calculated by the Kaplan-Meier method. Factors possibly affecting survival were assessed by multivariate analysis in the Cox proportional hazard model, such as maximum tumor size, number of lesions, portal vein invasion, and etc. The median overall survival was 9.2 months (95% CI: 6.94 - 11.46) in the study group versus 5.87 months (95% CI: 4.21 - 7.52) in the control group. In the study group,survival rates of the 1-, 2- and 3-year follow-up were 41.2%, 18.4%, and 9.6%, respectively. Significant independent prognostic factors identified by the Cox regression analysis were as follows: serum hepatitis B surface antigen (HBsAg) (P = 0.014), maximum tumor size (P = 0.027), number of lesions (P < 0.001), portal vein invasion (P < 0.001), and the therapy model (P = 0.006). Combination therapy of TACE and JDF granule preparation may significantly prolong survival of patients with unresectable HCC.

    ABSTRACT: To observe sublingual vein characteristics and the expressions of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1alpha (HIF-1alpha) proteins in sublingual tissues of Beagle dogs with cirrhotic portal hypertension. Twelve Beagle dogs were randomly divided into normal control group and cirrhotic portal hypertension group. There were 6 dogs in each group. A canine model of cirrhosis portal hypertension was established by injecting dimethylnitrosamine (DMN) into portal vein once a week for 7 weeks. The characteristics of sublingual vein were observed. Portal venous pressure was measured by using bioelectric recording techniques. The expressions of VEGF and HIF-1alpha proteins in sublingual vein were detected by immunohistochemical method. The shape and color of sublingual vein in beagle dogs in the cirrhotic portal hypertension group changed obviously as compared with the normal control group. Immunohistochemical results showed that there were almost no expressions of VEGF and HIF-1alpha proteins in sublingual tissues in the normal control group; however, the expressions of VEGF and HIF-1alpha proteins in sublingual tissues in the cirrhotic portal hypertension group significantly increased. Changes of portal pressure may lead to the formation of the abnormal sublingual vein by increasing the expressions of VEGF and HIF-1alpha proteins in sublingual tissues in Beagle dogs with portal hypertension.

    ABSTRACT: To observe the effects of cinobufacini injection on serum levels of thyroid-stimulating hormone (TSH) and adrenaline (ADR) in rats, and to speculate the property (cold or heat) of the drug. Thirty-two male Wistar rats were randomly divided into normal control group, cinobufacini injection group, cold syndrome group and heat syndrome group. The rats in the four groups were administered with normal saline, cinobufacini injection, and compound of traditional Chinese drugs with heat or cold property. The weights, and the serum TSH and ADR levels of the rats were measured before and after the interventions. The weights of the rats in heat syndrome group markedly decreased after 14-day administration when compared with the normal control group (P < 0.05). There were no significant differences among the normal control group, heat syndrome group and the cinobufacini injection group. Although no statistical difference was noted, the serum TSH levels of the cold syndrome group and cinobufacini injection group were slightly lower than that in the normal control group after 14-day administration, and the heat syndrome group showed a slightly higher serum TSH level. After administration, the serum ADR levels of the cold syndrome group and cinobufacini injection group were significantly lower than that in the normal control group (P < 0.05), and the serum ADR level in the heat syndrom group was higher than that in the normal control group (P < 0.05). Cinobufacini injection seemed to be able to suppress the thyrotrophin-releasing hormone-TSH-thyroxine system and sympathetic nervous system, matching up with the characteristics of the Chinese herbs of cold property. And the study provided initial experiment evidence for the conclusion that the property of cinobufacini might be cold.

    ABSTRACT: Objective: To investigate the effects of a formula of components from Shengmai Powder, a compound traditional Chinese herbal medicine, on glucocorticoid receptor (GR) in rats after thermal injury. Methods: A total of 32 male SD rats were randomly assigned into normal control group, untreated group, ginsenosides group and components group, with 8 rats in each group. Rats in the normal control group were intragastrically administered with normal saline (NS) at room temperature once daily. Rats in the untreated group were treated with NS before thermal injury, and rats in the components group and ginsenosides group were once daily treated with a mixture of aqueous extracts of Ophiopogonis Japoni, Fructus schizandrae Chinensis and ginsenosides and ginsenosides respectively. Rats were administered for one week. After the last administration, rats in the untreated group and treated groups underwent thermal injury for one hour, and then were sacrificed immediately by decapitation. Blood serum was collected, and the serum corticosterone (CS) and adrenocorticotropic hormone (ACTH) levels were determined with enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) respectively. The liver, lung and kidney homogenates were used to determine the GR binding capacity by radioligand receptor binding assay. The results were analyzed by one point analysis. Results: GR binding capacities in liver, lung and kidney cytosols in the untreated group were obviously lower than those in the normal control group (P<0.01). The GR binding capacities in the liver and lung cytosols in the components group and the ginsenosides group were significantly higher than those in the untreated group (P<0.01), but no significant difference was found in kidney cytosol. Compared with the ginsenosides group, GR binding capacity in liver cytosol in the components group was increased (P<0.01), but there were no noticeable differences when compared with the GR binding capacities in lung and kidney cytosols. Serum CS and ACTH levels of the normal rats were (66+/-16)microg/L and (59+/-18) ng/L respectively. There were significant differences in CS and ACTH levels between the normal control group and the other groups (P<0.01), in which the serum CS and ACTH levels were (113+/-33)microg/L and (125+/-20) ng/L, (123+/-26) microg/L and (110+/-30) ng/L and (118+/-17) microg/L and (115+/-35) ng/L respectively. But there was no significant difference between the untreated group and the other treated groups. Conclusion: The formula of components from Shengmai Powder can enhance the effect of ginsenosides in up-regulating GR in rats after thermal injury.

    ABSTRACT: Promoting apoptosis is a strategy for cancer drug discovery. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis in a wide range of malignant cells. However, several cancers, including human hepatocellular carcinoma (HCC), exhibit a major resistance to TRAIL-induced cell death. Melittin, a water-soluble 26-amino acid peptide derived from bee venom of Apis mellifera, can exert toxic or inhibitory effects on many types of tumor cells. Here we report that melittin can induce apoptosis of HCC cells by activating Ca2+/calmodulin-dependent protein kinase, transforming growth factor-beta-activated kinase 1 (TAK1), and JNK/p38 MAPK. We show that melittin-induced apoptosis can be inhibited by calcium chelator, by inhibitors for Ca2+/calmodulin-dependent protein kinase, JNK and p38, and by dominant negative TAK1. In the presence of melittin, TRAIL-induced apoptosis is significantly increased in TRAIL-resistant HCC cells, which may be attributed to melittin-induced TAK1-JNK/p38 activation and melittin-mediated inhibition of IkappaBalpha kinase-NFkappaB. Our data suggest that melittin can synergize with TRAIL in the induction of HCC cell apoptosis by activating the TAK1-JNK/p38 pathway but inhibiting the IkappaBalpha kinase-NFkappaB pathway. Therefore, the combination of melittin with TRAIL may be a promising therapeutic approach in the treatment of TRAIL-resistant human cancer.

    ABSTRACT: To assess the therapeutic effects of Sisheng Decoction, a compound traditional Chinese herbal medicine, on a mouse model of yin deficiency syndrome induced by thyroid hormone, and to make the preliminary study on its mechanisms. Simultaneous modeling and treatment were carried out. Sixty mice were randomly divided into six groups: normal group, yin deficiency model group, low-, medium- and high-dose Sisheng Decoction group and Shengmai oral liquid group. Normal group and yin deficiency model group were administered with double distilled water. Spontaneous activity and serum concentration of malondialdehyde in different groups were detected. The symptoms of yin deficiency syndrome such as xerostomia, dysphoria and fervescence were improved in the Sisheng Decoction groups. Compared with the yin deficiency model group, the spontaneous activity was increased and the serum concentration of malondialdehyde was decreased in the Sisheng Decoction groups (P<0.05). There was no significant difference between the Sisheng Decoction groups and the Shengmai oral liquid group (P<0.05). Medium- or high-dose Sisheng Decoction is effective for nourishing yin, clearing heat, engendering liquid and allaying thirst. The above effects of Sisheng Decoction may be realised by improving the spontaneous activity and resisting oxidative damage.
