ABSTRACT
ObjectiveTo explore the effect and mechanism of Sishenjian on synovial lesions induced by monosodium iodoacetate （MIA） in rats with knee osteoarthritis （KOA）. MethodSixty female Sprague-Dawley （SD） rats were randomly divided into the following six groups： normal group， model group， celecoxib group， and high-， medium-， and low-dose Sishenjian group. The KOA rat model was established by intra-articular injection of MIA. Celecoxib （18 mg·kg-1） and Sishenjian （14.4， 7.2， 3.6 g·kg-1） were administered by gavage according to the groups. All rats were euthanized after four weeks of continuous administration. The transverse diameter of the bilateral knee joints of rats was measured， and gross observation of the knee joint was performed. Pathological changes in knee joint synovial tissue were observed by hematoxylin-eosin （HE） staining and picrosirius red staining. Immunohistochemistry （IHC） was used to detect the expression of vascular endothelial growth factor A （VEGFA） in synovial tissue. The levels of inflammatory cytokines in the joint synovial fluid were detected by enzyme-linked immunosorbent assay （ELISA）. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the expression of mRNA and proteins related to the transforming growth factor-β1 （TGF-β1）/Smad2/3 pathway in knee joint synovium. ResultCompared with the normal group， the transverse diameter of the knee joint in the model group significantly increased （P<0.01）. Compared with the model group， the transverse diameter of the knee joint in rats of each Sishenjian group significantly decreased （P<0.01）. Compared with the normal group， the expression levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the knee joint synovial fluid of model group significantly increased （P<0.01）. Compared with the model group， the expression levels of IL-1β and TNF-α in the knee joint synovial fluid of rats in each Sishenjian group significantly decreased （P<0.01）. Compared with the normal group， the expression levels of TGF-β1， Smad2/3， phosphorylation（p）-Smad2/3， type Ⅰ collagen α1 （ColⅠα1）， type Ⅲ collagen α1 （ColⅢα1）， VEGFA proteins and TGF-β1， Smad2/3， ColⅠα1， ColⅢα1 mRNA in knee joint synovium of model group significantly increased （P<0.01）. Compared with the model group， the expression levels of TGF-β1， Smad2/3， phosphorylation （p）-Smad2/3， ColⅠα1， ColⅢα1， VEGFA proteins and TGF-β1， Smad2/3， ColⅠα1， ColⅢα1 mRNA in knee joint synovium of rats in each Sishenjian group significantly decreased （P<0.05， P<0.01）. ConclusionSishenjian can inhibit synovial inflammation and angiogenesis， and may become a potential drug for treating synovial lesions in KOA by regulating the TGF-β1/Smad2/3 pathway.
ABSTRACT
AIM To study the effects of No.1 Weiyan Decoction (Codonopsis Radix,Paeoniae Radix alba,Taraxaci Herba,etc.) on hypoxia and hypoxic tolerance in gastric mucosal epithelial cells in rats with precancerous lesion of gastric cancer (PLGC).METHODS Forty rats were randomly divided into normal,model,Vitacoenzyme Tablets and No.1 Weiyan Decoction groups.Except for the normal group,the rats in the other groups were given with N-methyl-N'-nitro-N-nitrosoguanidine and Little Chengqi Decoction to establish a PLGC rat model.Ten weeks after the administration,the gastric mucosal epithelial microvascular ultrastructure was observed,the expressions of Hif1a mRNA,HIF-1 α protein and VEGF protein in gastric mucosal epithelium were detected.RESULTS Compared with the normal group,the number of microvasculatures in gastric mucosal epithelium was decreased;lumen was severely stenosed or expansive;inner wall was not smooth and had adhesion;vascular endothelial cells were swollen;the expression of Hif1α mRNA showed an increasing trend;the expressions of HIF-1α protein and VEGF protein were anomalous in the model group.Compared with the model group,the gastric mucosal vascular lesion of PLGC rats was improved,and the expressions of Hif1a mRNA,HIF-1α protein and VEGF protein were significantly decreased in the No.1 Weiyan Decoction group.CONCLUSION No.1 Weiyan Decoction can improve hypoxia and hypoxia tolerance,and induce angiogenesis in gastric mucosal epithelium in PLGC rats.

ABSTRACT
Objective To compare two types of digestive reconstruction and postoperative complications after total gastrectomy in patients with gastric carcinoma. Methods Roux-en-Y esophagojejunostomy and P-type Roux-en-Y esophagojejunostomy were performed in 50 patients with gastric carcinoma after total gastrectomy. The operating time and postoperative complications were observed. Results The gastrointestinal symptoms for Roux-en-Y esophagojeju-nostomy and P-type Roux-en-Y esophagojejunostomy serve as : diarrhea ( 11.8% and 12.1% ), dumping syndrome (3.9% and 3.3% ) and reflux esophagitis(5.9% and 6.0% ) ,the incidence of the difference was not significant ( than,P>0.05 ). The postoperative complications in P-type Roux-en-Y esophagojejunostomy( 13.1% ) slightly higher that Roux-en-Y esophagojejunostomy( 11.1% ) ,but the difference was not significant( P>0.05 ). Roux-en-Y esoph-agojejunostomy average operative time(3.1±0.3)h was significantly reduced than P-type Roux-en-Y esophagojeju-nostomy(3.7±0.2)h(t=3.35,P<0.05). Conclusion Roux-en-Y esephagojejunostomy and P-type Roux-en-Y esophagojejunostomy is a suitable type after total gastrectomy for patients with gastric carcinoma, but the former opera-tive time was shorter.
ABSTRACT
Objective To observe the effect of treating chronic severe hepatitis modified Yinchen Zhufu Decoction.Methods 46 chronic severe hepatitis patients (belonging to Ymhuang syndrome in TCM) were randomly recruited in to a treatment group (26 cases) and a control group (20 cases). Indexes as symptoms, signs, liver functions, prothrombin activity (PTA), prothrombin (ALB) and complications were used for evaluating therapeutic effects. Results After four weeks' treatment, of all 26 cases in the treatment group, 23 cases were effective (occupying 88.5%) and 3 cases were inefficacy (occupying 11.5%); while of all 20 cases in the control group, 11 cases were effective (occupying 55%) and 9 cases were inefficacy (occupying 45%). There was significant difference between the two group in therapeutic effects( P＜0.05 ). TBIL in both groups were decreased after the treatment(P＜ 0.05 ), and the decrease amplitude in the treatment group was much bigger than the control group (P＜0.05). PTA in the treatment group was increased after the treatment (P＜0.05), but this increase amplitude showed no significant difference comparing with the control group (P＞0.05). ALB showed significant difference between the two groups after treatment, with P＜0.05, but complications demonstrated no significant difference between the two groups after treatment, with P＞0.05. Conclusion Modified Yinchen Zhufu Decoction has good therapeutic effects in treating chronic severe hepatitis of yinhuang syndrome.
