ABSTRACT: Introduction. Posttraumatic stress disorder (PTSD) is accompanied by poor general psychological status (GPS). In the present study, we investigated the effects of a Chinese herbal formula on GPS in earthquake survivors with PTSD. Methods. A randomized, double-blind, placebo-controlled trial compared a Chinese herbal formula, Xiao-Tan-Jie-Yu-Fang (XTJYF), to placebo in 2008 Sichuan earthquake survivors with PTSD. Patients were randomized into XTJYF (n = 123) and placebo (n = 122) groups. Baseline-to-end-point score changes in the three global indices of the Symptom Checklist-90-Revised (SCL-90-R) and rates of response in the SCL global severity index (GSI) were the primary endpoints. A subanalysis of the nine SCL factors and the sleep quality score were secondary endpoints. Results and Discussion. Compared to placebo, the XTJYF group was significantly improved in all three SCL global indices (P = 0.001~0.028). More patients in the XTJYF group reported "much improved" than the placebo group (P = 0.001). The XTJYF group performed significantly better than control in five out of nine SCL factors (somatization, obsessive-compulsive behavior, depression, anxiety, and hostility (P = 0.001~0.036)), and in sleep quality score (P < 0.001). XTJYF produced no serious adverse events. These findings suggest that XTJYF may be an effective and safe treatment option for improving GPS in patients with PTSD.

ABSTRACT: Drug resistance is a major factor for the limited efficacy of chemotherapy in gastric cancer treatment. Hypoxia-inducible factor-1α (HIF-1α), a central transcriptional factor in hypoxia, is suggested to participate in the resistance. Here, we identified a hypoxia-mimic (cobalt chloride) sensitive gastric cell line BGC-823 to explore whether diosgenin, an aglycone of steroidal saponins, can inhibit cancer cell invasion and survival of solid tumor in a hypoxic mimic microenvironment. We have shown that diosgenin is a potent candidate for decreasing the ability of invasion and survival in cobalt chloride treated BGC-823 cells. In addition, when combined with HIF-1α specific short hairpin RNA (shRNA), diosgenin can inhibit BGC-823 cells more effectively. The anti-invasion role of diosgenin may be related to E-cadherin, integrinα5 and integrin β6. These results suggest that diosgenin may be a useful compound in controlling gastric cancer cells in hypoxia condition, especially when combined with down-regulated HIF-1α.

ABSTRACT: To observe the effects of serum containing Xiaotan Sanjie Decoction, a compound traditional Chinese herbal medicine, on proliferation and apoptosis of human gastric cancer cell line MKN-45.
After coculturing MKN-45 cells with low-, medium- and high-dose Xiaotan Sanjie Decoction-containing serum, inverted microscope was utilized to observe morphological changes and counting chamber was used to count the MKN-45 cells; the proliferation of MKN-45 cells was determined by cell counting kit 8; Annexin V-fluorescein isothiocyanate/propidium iodide double label method was used to detect apoptosis rate of MKN-45 cells.
Xiaotan Sanjie Decoction-containing serum significantly inhibited the proliferation of MKN-45 cells. The typical morphological changes of apoptotic MKN-45 cells were observed after treating with Xiaotan Sanjie Decoction-containing serum. The cell apoptosis was also observed by flow cytometry and the apoptosis rates of medium- and high-dose Xiaotan Sanjie Decoction-containing serum groups were higher than that of low-dose group.
Xiaotan Sanjie Decoction-containing serum can inhibit the MKN-45 cell proliferation and induce cell apoptosis, which provides an experimental evidence for its treatment of human gastric cancer.

ABSTRACT: To establish nude mouse human gastric cancer orthotopic transplantation models using OB glue paste technique.
Using OB glue paste technique, orthopic transplantation models were established by implanting SGC-7901 and MKN-45 human gastric cancer cell strains into the gastric wall of nude mice. Biological features, growth of the implanted tumors, the success rate of transplantation and the rate of auto-metastasis of the two models were observed.
The success rates of orthotopic transplantation of the two models were 94.20% and 96%. The rates of hepatic metastasis, pulmonary metastasis, peritoneal metastasis, lymphocytic metastasis and splenic metastasis were 42.13% and 94.20%, 48.43% and 57.97%, 30.83% and 36.96%, 67.30% and 84.06%, and 59.75% and 10.53%, respectively. The occurrence of ascites was 47.80% and 36.96%.
OB glue paste technique is easy to follow. The biological behaviors of the nude mouse human gastric cancer orthotopic transplantation models established with this technique are similar to the natural processes of growth and metastasis of human gastric cancer, and, therefore, can be used as an ideal model for experimental research of proliferative metastasis of tumors.

ABSTRACT: Chinese medicine has been used in treating pain for a long time. Much progress has been made in studies on the mechanism of the analgesic effect of Chinese medicine in animal experiments. It is found that the analgesic action may be related to the following actions: (1) Reducing the secretion of peripheral algogenic substances and inducing the secretion of pain-sensitive substances; (2) Alleviating the accumulation of local algogenic substances; (3) Increasing the release of endogenous analgesic substances; (4) Regulating c-fos gene and increasing the secretion of such substances in the central nervous system, etc. In this paper, the experimental methods and analgesic effect of Chinese medicines are reviewed.

ABSTRACT: To assess the effects of Jinlongshe Granules (JLSG) on tumor growth of gastric carcinoma.
Fifty nude mice orthotopically transplanted with MKN-45 human gastric cancer cells were divided into five groups: untreated group, 5-fluorouracil (5-FU)-treated group and high-, medium-, and low-dose JLSG-treated groups. Corresponding antitumor drugs were administered in each group except the untreated group. The antitumor effects in vivo were evaluated. Cell cycle distribution and apoptosis of MKN-45 human gastric cancer cells were determined by using flow cytometry (FCM) and Annexin V-fluorescein isothiocyanate/propidium iodide (Annexin V-FITC/PI) staining assay. The ultrastructure of MKN-45 gastric cancer cells was observed by transmission electron microscope.
In the mice treated with high-, medium-, and low-dose JLSG, the growth inhibition rates of gastric cancer were 68.13%, 55.94% and 50.31% respectively, and this antitumor effect was dose-dependent. In the mice treated with intraperitoneal injection of 5-FU, the growth inhibition rate of gastric cancer was 53.43% and not much different from those treated with JLSG. The apoptotic rates in the high-, medium-, and low-dose JLSG-treated groups were 22.81%, 28.27% and 38.54% respectively, in a dose-dependent manner, with the cell cycle arrested at G(0)/G(1) phase. An Annexin V-FITC/PI staining assay revealed that the percentages of early apoptotic cells in the three dose JLSG-treated groups were all significantly higher than that in the 5-FU-treated group, whereas the late apoptotic and necrotic cells were much more in the 5-FU-treated group than those in the three dose JLSG-treated groups.

ABSTRACT: To study the antitumor effect of Chinese compound jinlongshe (JLS) granules on sarcoma 180 and MKN-45 human gastric cancer cell lines in vivo and its mechanism.
After establishment of S180 sarcoma (S180) and MKN-45 gastric cancer model of nude mice, the tumor-bearing mice were divided into 5 groups at random. Three experimental groups were respectively given the aqueous extract of JLS granules at doses of 120 g, 60 g and 20 g/(kg per 6/wk, i.g.) for 3 wk in S180 and 6 wk in nude mice model. Positive control was given cyclophosphamide (Cy) at a dose of 50 mg/(kg per 3/wk, i.g.) for 3 wk in S180 models and 5-Fluorouracil (5-FU) 20 mg/(kg per 3/wk, i.g.) for 3 wk in nude mice model. Negative control was given normal saline (NS) at a dose of 0.18 g/(kg per 6/wk, i.g.) respectively. After 3 wk in mice bearing S180 tumor and 6 wk in nude mice model, the experimental animals were sacrificed and the masses of tumor were weighed, and the rates of tumor inhibition of each treated group were calculated respectively. To determine the antitumor mechanisms, the morphological changes, cell cycle and apoptosis were observed in MKN-45 nude mice model. Annexin V-FITC/PI double staining FCM assay was used to further determine the live cells, apoptotic cells, necrotic cells and debris.
The inhibitory rates of JLS granules at the doses of 20 g/kg, 60 g/kg and 120 g/kg were 50.31%, 55.94% and 68.13% (P < 0.01) in nude mice models and 40.90%, 50.32% and 58.46% (P < 0.01) in S180 model. The inhibitory rate of Cy was 85.22% in S180 models and the inhibitory rate of 5-FU was 53.43% in nude mice model (P < 0.01). Nuclear chromatin and margination were observed under a transmission electron microscope (TEM). The G0/G1 phase was arrested, typical apoptotic peak appeared, the apoptotic rate was 22.81%-38.54% in three JLS granule-treated groups. Annexin V-FITC/PI double staining FCM assay showed that the apoptotic cells were 4.36%, 3.08% and 7.08% in three dosages, most cells were localized in the low right quadrant.
Jinlongshe granules possess anti-tumor effects on experimental tumor models in vivo, and apoptosis induction is one of its anti-tumor mechanisms.
