Protective effect of Phaeoporus obliquus polysaccharide against acute liver injury induced by carbon tetrachloride and alcohol in mice.

Studied the optimum extraction process of polysaccharide from Phaeoporus obliquus and the effect of Phaeoporus obliquus polysaccharide on carbon tetrachloride (CCl4)- or alcohol-induced acute liver injury in mice. The main factor in influencing the extraction rate of Phaeoporus obliquus polysaccharide were extraction power and time, which was a kind of pyran glucose by infrared spectroscopy. CCl4 and alcohol were employed respectively to establish CCl4 and alcohol-induced acute liver injury mouse models. Compared with model groups mice, Phaeoporus obliquus polysaccharide treatment at the doses of 100mg/kg and 200mg/kg exhibited an obvious reduction liver index, ALP, ALT, AST levels, MDA content and TNF-α level (p<0.01) and SOD activity was increased, which was in a dose-dependent manner. Compared with the model group, the necrosis degree of hepatocytes was obviously reduced and the small fat droplets were formed in some cytoplasm, especially in high dose group, which the liver cells recovered to the level of normal group. Rt-PCR results showed that the expression of CYP2E1 mRNA in liver tissues of Phaeoporus obliquus polysaccharide groups were significantly reduced, and the difference were statistically significant compared with the model group (p<0.05). These results demonstrated that Phaeoporus obliquus polysaccharide has significantly hepatoprotective effect on CCl4 and alcohol-induced acute liver injury in mice.

Randomized Controlled Trial of Acupuncture at Gastrointestinal Back-Shu and Front-Mu Points for Post-stroke Constipation / 上海针灸杂志

Objective To investigate the clinical efficacy of acupuncture at gastrointestinal Back-Shu and Front-Mu points for post-stroke functional constipation. Method Sixty-six patients with post-stroke functional constipation were randomized to treatment and control groups, 33 cases each. The treatment group received acupuncture at gastrointestinal Back-Shu and Front-Mu points: Weishu (BL21), Dachangshu (BL25), Xiaochangshu (BL27), Zhongwan (CV12), Tianshu (ST25) and Guanyuan (CV4). The control group took Chinese herbal medicine Liumo Decoction prescribed originally. The clinical therapeutic effects were compared between the two groups. The CCS score was recorded and fecal characteristics were scored in the patients at baseline, during treatment and at follow-up. Result The total efficacy rate was 90.9％ in the treatment group and 42.4％ in the control group. The CCS score and the fecal characteristic score were lower in the two groups after treatment compared with before (P<0.05) and the therapeutic effect was more marked in the treatment group (P<0.05). The CCS score and the fecal characteristic score increased in the two groups at follow-up, but the increments were significantly smaller in the treatment group than in the control group (P<0.05). Conclusion Shu-Mu point combination acupuncture can significantly relieve the symptoms of post-stroke functional constipation and change fecal characteristics. It is superior to Chinese herbal treatment alone.

Comparison of two types of digestive tract reconstruction after total gastrectomy in patients with gastric carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the influence of two different types of digestive tract reconstruction on the life quality, nutritional status and tolerance to adjuvant chemotherapy after total gastrectomy in patients with gastric carcinoma.</p><p><b>METHODS</b>The clinical data of a total of 107 patients treated in our department from January 2005 to december 2008 were analyzed retrospectively. Among them, 49 patients underwent digestive tract reconstruction with functional jejunal interposition (FJI group) and 58 patients underwent Roux en-Y jejunal P-type anastomosis (PR group) after total gastrectomy. 79 of 107 (73.8%) patients received postoperative adjuvant chemotherapy with XELOX regimen. The digestive complications and tolerance to chemotherapy were assessed respectively.</p><p><b>RESULTS</b>Neither severe complications nor surgery-related or chemotherapy-related death were observed among the 107 patients. There were statistical differences in the incidence rate of emaciation, dumping syndrome and retention syndrome between the FJI and PR groups (P < 0.05), but no significant statistical difference in incidence rate of reflux esophagitis (P > 0.05). 28 of 40 (70.0%) patients in the FJI group completed all six cycles of chemotherapy, while 12 (30.0%) patients interrupted the treatment due to chemotherapy-related toxicity. 39 patients in the PR group received chemotherapy, 19 (48.7%) of them completed 6 cycles of chemotherapy but 20 (51.3%) patients interrupted. There was a significant difference in the incidence rate of grade III/IV chemotherapeutic toxicity and completion rate of chemotherapy (P < 0.05).</p><p><b>CONCLUSIONS</b>Both functional jejunal interposition and Roux-Y operation are reasonable and safe procedures of digestive tract reconstruction. The incidence rates of emaciation, dumping syndrome and retention syndrome are lower in the patients with FJI, showing a better tolerance to adjuvant chemotherapy than Roux en-Y jejunal p type anastomosis.</p>

Study on syndrome element characteristics and its correlation with coronary angiography in 324 patients with coronary heart disease / 中国结合医学杂志

<p><b>OBJECTIVE</b>Recently, a new traditional Chinese medicine differentiation theory "Syndrome Element (SE)" has been raised. In this study, the main syndrome element types and their correlations with the results of coronary angiography (CAG) in patients with coronary heart disease (CHD) were investigated.</p><p><b>METHODS</b>Epidemiology cross-sectional study method was employed and 324 patients with CHD were enrolled, and their syndrome element types as well as the CAG results were analyzed. The correlations among syndrome element types, Gensini score, and the number of abnormal branches were also analyzed based on the distribution characteristics of syndrome element and coronary angiography results in the 324 cases.</p><p><b>RESULTS</b>According to their occurrence frequency in 324 CHD patients, the top eight major heart syndrome elements were Xin () blood stasis (85.8%), Xin qi deficiency (79.6%), Xin heat blockage (41.1%), Xin phlegm with turbid fluid (38.0%), Xin qi stagnation (24.7%), Xin yang deficiency (18.9%), Xin yin deficiency (17.5%) and Xin cold coagulation (4.4%), respectively, which suggested that Xin blood stasis and Xin qi deficiency were the two most common syndrome elements. Also, as coronary artery Gensini score increased, the changing trend of the syndrome element was "Xin yang deficiency with blood stasis" to "Xin phlegm obstruction with heat blockage" to "Xin yin deficiency with blood stasis" to "Xin qi deficiency with blood stasis" to "Xin cold coagulation with phlegm and turbid fluid, "Xin cold coagulation with blood stasis" to "Xin deficiency of qi, yin and yang". As the number of abnormal branches increased, the syndrome element changing trend was "simultaneous occurrence of cold and heat syndrome" to "Xin qi and yang deficiency with blood stasis" to "Xin retention of phlegm with turbid fluid" to "Xin cold coagulation in the heart meridian", "Xin deficiency of both qi and yin". The result of this study shows that Xin qi deficiency and Xin blood stasis were the major syndrome elements in patients with CHD.</p><p><b>CONCLUSION</b>As the severity and extent of coronary artery lesion increased, there were some apparent correlations among syndrome elements, Gensini score and number of abnormal coronary artery branches.</p>
