    ABSTRACT: Leptomeningeal involvement is usually reported as a secondary event in advanced gastric carcinoma. Leptomeningeal carcinomatosis (LMC), as the initial manifestation of asymptomatic gastric cancer, is exceedingly rare with only a few cases reported in recent years. The presenting neurologic symptoms include headache, vomiting and seizures and are usually clinically atypical. The diagnosis of LMC is made via identification of malignant cells that originate from epithelial cells in the cerebrospinal fluid by cytological examination and provides cues to track the primary tumor. Endoscopic examinations are crucial to confirm the presence of gastric cancer, and imaging studies, especially gadolinium-enhanced magnetic resonance imaging of the brain, are sometimes helpful in diagnosis. Thus far, there is no standard therapy for LMC, and despite all measures, the prognosis of the condition is extremely poor. Here, we report on the clinical features and diagnostic procedures for a patient with occult gastric cancer with Bormann type I macroscopic appearance and poor differentiation in pathology, who presented with LMC-induced neurological symptoms as the initial clinical manifestation. Additionally, we review the similar cases reported over the past years, making comparison among cases in order to provide more information for the future diagnosis.

    ABSTRACT: To observe the effect of integrative medical therapy on the prognosis of patients suffering from yin syndrome type acute ischemic stroke (YS-AIS). A multi-center, prospective, random and parallel controlled clinical trial was carried on 606 patients of YS-AIS. Excepting the 15 patients being excluded and dropped out in the trial period, all patients were assigned to the treatment group (274 patients) treated with integrated medical protocol (i. e. Chinese medical therapy plus conventional Western medical treatment), and the control group (263 patients) treated with conventional Western medical treatment plus placebo. Patients' quality of life (QOL) and their disability level were assessed by scoring based on SS-QOL and modified Rankin scale (mRS) respectively at the terminal of the 21-day treatment (T1) and at the ends of 60-day (T2) and 90-day (T3) following-ups. Patients' disability level, showed by mRS scores, was not significantly different between the two groups at T1 and T2 (P > 0.05), but with significant difference at T3 (P < 0.05). The recovery in the treatment group were more significant. Although the SS-QOL scores showed no statistical significant difference between groups (P > 0.05), improvement of QOL could be seen in the treatment group and the difference between groups was more significant as the time went by. Integrative medical therapy could reduce the severe disability rate in patients after YS-AIS, and showed an improving trend on patients' QOL at T3.

    ABSTRACT: Subcortical ischemic vascular dementia (SIVD) has been proposed as the most frequent subtype of vascular cognitive impairment. The aim of this study was to evaluate the psychometric properties of the Chinese (Cantonese) Montreal Cognitive Assessment (CC-MoCA) in patients with SIVD in the Guangdong Province of China. 71 SIVD patients and 60 matched controls were recruited for the CC-MoCA, Mini Mental State Examination and executive clock drawing tasks. Receiver-operating characteristic curve analyses were performed to determine optimal sensitivity and specificity of the CC-MoCA total score in differentiating mild vascular dementia (VaD) patients from moderate VaD patients and controls. The mean CC-MoCA scores of the controls, and mild and moderate VaD patients were 25.2 ± 3.8, 16.4 ± 3.7, and 10.0 ± 5.1, respectively. In our study, the optimal cutoff value for the CC-MoCA to be able to differentiate patients with mild VaD from controls is 21/22, and 13/14 to differentiate mild VaD from moderate VaD. The CC-MoCA is a useful cognitive screening instrument in SIVD patients.

    ABSTRACT: The priority of the modernization of Chinese medicine at present is the standardization of Chinese medicine practice, including syndrome differentiation, disease diagnosis, standardized therapeutic program, etc. For this reason, the primary work is to establish a concise disease-syndrome differentiation and treatment system (CDSDTS) under the guidance of Chinese medicine theory, holding the core advantages and effectiveness of Chinese medicine, and aiming at creating a simplified theoretical and practical program facilitating for operation and spreading. It is not a mere simplification or careless reduction, but a normalized program of treatment according to the essence of Chinese medicine. Although the therapeutic effect might be somewhat lost, it can be widely approved, thereby, it would make contributions for the inheritance and development of Chinese medicine.

    ABSTRACT: To explore the dynamic state of traditional Chinese medicine (TCM) syndromes in acute ischemic stroke patients within 30 days of onset when treated with acupuncture, and to analyze the discrimination effects of the functions based on "decision trees" in identification of TCM syndromes of ischemic stroke. A total of 264 cases with acute ischemic stroke regularly treated by acupuncture were included. Unified syndrome questionnaire was made by document retrieval and expert advice. The syndrome elements of the patients with acute ischemic stroke were surveyed on any day of three time periods (days 0-3, 4-10 and 11-30). The study was performed on multitime dynamic state results and correlated factors of basic TCM syndromes of the 264 patients. Bayes discriminant function of four syndromes of acute ischemic stroke on the basis of "decision trees" was used for computing the rate of miscarriage justice by original test and cross-validation, and the discrimination effects of "decision trees" were evaluated too. Wind, phlegm, fire-heat, qi deficiency, blood stasis, and hyperactivity of yang due to yin deficiency syndromes were found in the patients with acute ischemic stroke treated by acupuncture on the first 30 days of onset, and the incidence rates were 80.7%, 68.9%, 52.7%, 50.8%, 29.2% and 25.0% respectively. The mean scores and incidence rates of the six syndromes decreased gradually on three-time-point, especially of blood stasis syndrome. The main combined-syndromes were two-syndrome, three-syndrome and four-syndrome, and three-syndrome was the most frequently encountered type. Single syndrome was not found in the patients with acute ischemic stroke on the first three days of onset. Two-syndrome combination types were wind-phlegm, wind-heat, wind combined with qi deficiency or phlegm stagnation due to qi deficiency, phlegm-heat and blood stasis combined with hyperactivity of yang due to yin deficiency, and the incidence rates were 54.5%, 42.8%, 40.9%, 39.4%, 35.6% and 3.8% respectively. The mean scores of phlegm and qi deficiency in high-age patients were higher than those in low-age patients. The mean score and incidence rate of qi deficiency in female patients were higher than those in male patients. The mean score of phlegm in female patients was higher than that in male patients. To simplify the "decision trees" composed of 21 items, the group of Bayes discriminant function including eight most significant items out of the original 21 items was set up. The discrimination effect of the eight items including reddish face, constipation, yellow tongue fur, short breath, bright-white or gray complexion, tinnitus, feverish palms and soles and scanty tongue fur was similar to that of the 21 items, and there was no significant difference between the two functions. Wind syndrome and phlegm syndrome are the major single syndromes occurring in acute ischemic stroke patients within 30 days of onset, and three-syndrome combination is the most frequent multiple syndrome type. After acupuncture treatment, some syndrome elements including wind, phlegm, fire-heat, qi deficiency, blood stasis, and hyperactivity of yang due to yin deficiency are gradually reduced, and combined syndrome type is gradually become simple. Eight syndrome element items including reddish face, constipation, yellow tongue fur, short breath, bright-white or gray complexion, tinnitus, feverish palms and soles and scanty tongue fur have important means in discriminating yin syndrome from yang syndrome and sthenia syndrome from asthenia syndrome.

    ABSTRACT: To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P<0.01). However, the percentages of the syndromes of blood stasis, qi deficiency, and yin deficiency and yang hyperactivity were similar at the three periods (P>0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (P<0.01), and the percentages of syndromes of blood stasis and qi deficiency were lower (P<0.05, P<0.01) in patients with yang syndrome than in patients with yin syndrome. The complex of three syndromes was the most frequent composition pattern in the patients at the three periods. The percentages of complex syndromes of four or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm. The main discrimination between the yin and yang syndromes is that the yang syndrome is characterized by pathogenic fire. The syndromes of phlegm, qi deficiency, and blood stasis are not associated with the diagnosis of yin or yang syndrome.

    ABSTRACT: To observe the effect of a comprehensive protocol of integrated Chinese and Western medicine (ICWM) in treating with acute ischemic stroke. A multi-center, prospective, random and control clinical trial was adopted with 606 patients of acute ischemic stroke. They were divided into the treatment group (274 cases) treated with ICWM protocol, and the control group (263 cases) treated with Western medicine plus placebe, and BI, mRS were assessed after treatment. Compared with the control group, the 90th day assessment showed that the severe disability rate was lower (BI <75) (P <0.05), the complete reabilitation and mild disability rate (BI> or =95, P < 0.05), and the disability level (modified Rankin scale mRS) were improved (P <0.05) in the treatment group than those in the control group. The ICWM protocol used in this study may improve neural function and quality of life of acute ischemic stroke patients, and reduce the severe disability rate in those after 90 days treatment.

    ABSTRACT: To explore the clinical evaluation system reflecting the superiority and characteristics of comprehensive traditional Chinese medicine (TCM) therapy for acute stroke. A randomized controlled trial with single blind in various therapeutic centers was applied on the patients with the acute stage of hemorrhagic stroke due to hypertension, who were allocated to the trial group and the control group. The trial group accepted the general Western medicine therapy and differential treatment of traditional Chinese medicine based on stage classification. Patients in the control group were treated with the general Western medicine and the placebo of traditional Chinese herbal medicine. The treatment effect was assessed at the 7th day, 14th day, 21st day, and 28th day of post-treatment and after 3-month follow-up. The clinical evaluation system included the syndromes of TCM (ZH), Glasgow coma standard (GCS), nerve functional failure (NF), activity of daily living (ADL), Barther index (BI), quality of life index (QLI) and functional activities questionnaire (FAQ). Four hundred and four patients with acute stroke were included. There were 178 cases with yang-syndrome and 21 cases with yin-syndrome in the trial group (n=199), and there were 165 cases with yang-syndrome and 40 cases with yin-syndrome in the control group (n=205). The rates of recovery and obvious improvement after 3-month treatment in the trial group and the control group were 86.5% and 73.6% respectively. There was significant difference between the two groups (P<0.01). The response sensitivity of the effect items indicated that the sensitivity of GCS began to increase from the 7th day and was high at the 14th day and the 21st day for all patients. The response sensitivity of the NF scale was high for all patients at the 14th day, the 21st day and the 28th day. The BI scale and the QLI scale were sensitive to the patients with light and middle stage of stroke at the 21st day, and were sensitive to the patients with light stage of stroke after 3-month follow-up. The FAQ scale was sensitive to the light stroke at the 21st day and after 3-month follow-up. The ADL scale was sensitive to all patients at the 28th day and the patients with light stage of stroke after 3-month follow-up. The ZH scale was sensitive to all patients from 0 to 7d, the 14th day, and the 28th day. The principle components analysis indicated these 7 items could reflect the condition of stroke from 0-7d, the 21st day and after 3-month follow-up, and could be used to evaluate the therapeutic effect of hemorrhagic stroke. ZH scale and FAQ scale were more sensitive than other effect items at the 28th day. The seven items (GCSbNFbBIbQLIbFAQbADLbZH) have high sensibility to all patients in the acute stage of hemorrhage stroke especially at the 21st day. The ZH score will change in accord with the condition of stroke, and is appropriate to reflect the condition of stroke. It is believed that the seven items can form the system of effect evaluation in different stages of stroke, and the ZH scale is a very important item.

    ABSTRACT: Definite therapeutic effect has obtained by TCM in treating acute cerebral hemorrhage (ACH) according the TCM theory of "blood circulating outside the vessels is the stasis" using breaking stagnant and eliminating blood stasis (Poxue Zhuyu) method, but no material involving the natural development of stoke in superacue stage (0 - 4 hrs after onset of the disease) being presented so far. It has been proved by randomized, double-blinded multi-centeric clinical trials that recombinant activated factor VII (rF VII a) could decreased the morbidity and disability of patients suffered from ACH, suggesting that use hemostasis treatment in ACH during superacu stage should be stressed, and the drugs for Poxue Zhuyu should be used cautiously in the period of 0 - 4 hrs after onset. The hemorrhagic disorder could be eliminated by using drugs for Poxue Zhuyu and other medicines in rational combination.
