OBJECTIVE:To systematically evaluate therapeutic efficacy and safety of Yupingfeng powder in adjavant therapy of allergic rhinitis,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from Wanfang database,VIP,CJFD,CBM,Cochrane Library,EMBase and PubMed,RCTs about Yupingfeng powder combined with chemical medicine (trial group)vs. chemical medicine alone in the treatment of allergic rhinitis were collected. Meta-analysis was conducted by using Rev Man 5.2 statistical software after data extraction and quality evaluation according to Cochrane system evaluation method 5.1.0. RESULTS:A total of 15 RCTs were included,invovling 1366 patients. The results of Meta analysis showed that response rate [OR=3.95,95%CI(2.80,5.58),P<0.001],recurrence rate [OR=0.37,95%CI(0.22,0.63),P<0.001] and the incidence of ADR [OR=0.15,95%CI(0.06,0.35),P<0.001] in trial group were significantly higher than control group,with statistical significance. CONCLUSIONS:Yupingfeng powder in adjuvant therapy of allergic rhinitis show good therapeutic efficacy and can reduce recur-rence rate with good safety.

Objective To establish a rat model of superior mesenteric vein thrombosis by vein ligation and to simulate the pathological process of the disease, and to provide the basis for studies of its pathogenesis and treatment.Methods Ninety-six SPF male SD rats were randomly divided into three groups: Group A (sham operation group), group B (strangulation group) and group C (simple group), 32 rats in each group.Rats in group A were only opened the abdominal cavity but not blocked the blood supply.The rats were sacrificed at 8, 24, 48 and 72 h after operation.The rats in groups B and C were subjected to establish the strangulation and simple models by superior mesenteric vein thrombosis, respectively, and were sacrificed at 8, 24, 48 and 72 h after modeling.Histological changes (H&E staining) in the rat intestinal tissues were evaluated by a pathological scoring system.The levels of intestinal fatty acid binding protein (IFABP) and α-glutathione S-transferase (α-GST) were detected by ELISA.Results The rat model of mesenteric vein thrombosis was successfully established, with a success rate of 100% (96/96).The pathological analysis revealed that compared with the group A, different degrees of blood stasis and injuries were observed in the intestinal tissues of groups B and C, and the injury were gradually increased in the group B, while gradually reduced in the group C.The degrees of blood stasis and injury were positively correlated with the scope of ligation.The result of ELISA showed that the serum levels of IFABP and α-GST of the rats in groups B and C were significantly higher than those in group A (P < 0.05), and the degree of elevation was positively correlated with the scope of ligation.Conclusions In this study, the rat model of superior mesenteric vein thrombosis is successfully established by vein ligation.This model is simple and easy to operate with a high success rate, and can be used in related research.

Objective To investigate the expression change of RACK1 ,Src and Bcl‐2 in gastric carcinoma tissue and adjacent carcinomatous tissue .Methods Eighty specimens of gastric carcinoma and adjacent carcinomatous tissues in our hospital from Au‐gust 1 ,2011 to February 1 ,2014 were collected .The immunohistochemistry staining and Western blotting methods were adopted to detect the expression of RACK1 ,Src and Bcl‐2 protein in gastric carcinoma and adjacent carcinomatous tissues ,and their correlation was analyzed and performed the statistical analysis by combining with the clinicopathological data .Results The immunohistochem‐istry staining and Western blotting detection displayed that the expression positive rate and expression level of RACK 1 in gastric carcinoma tissue were obviously lower than those in the adjacent carcinomatous tissue ,while the expression positive rate and ex‐pression level of Src and Bcl‐2 in gastric carcinoma tissue were obviously higher than those in the adjacent carcinomatous tissue ,the differences were statistically significant (P<0 .05) .The RACK1 expression in gastric carcinoma tissue was negatively correlated with the Src and Bcl‐2 expression(r= -0 .632 ,-0 .754 ,P<0 .01) ,while Src had no obvious correlation with Bcl‐2 protein(r=0 .217 ,P>0 .05) .Conclusion The expression of RACK1 in gastric carcinoma tissue is significantly decreased ,while the expres‐sions of Src and Bcl‐2 are increased .

Objective To explore the effect of TNF-αon expression of TROP-2 and to explore the role of TROP-2 in the metastasis and invasion of colon cancer HCT-116 cells. Methods HCT-116 cells were cultured and treated with 0, 10, 20, 30, 50, 100 and 200μg/L TNF-α. Cell viability was assessed by MTT. The expression of TROP-2 was determined by western blot. The effects of 20μg/L TNF-αon cell migration and invasion were investigated by wound healing assay and Transwell method. Small interfering RNA (siRNA) was used to knock down endogenous TROP-2 expression. The transcrip?tion and translation levels of TROP-2 were detected by qPCR and Western blot respectively. The migratory and invasive ca?pability of HCT-116 cells transfected with TROP-2 siRNA were checked by wound healing assay and Transwell method re?spectively. Results There is no significant change of cell viability between HCT-116 cells treated with 0,10, 20, 30 and 50μg/L TNF-α, but cell viability of HCT-116 decreased significantly with treatment of 100μg/L and 200μg/L TNF-α. Low concentration of TNF-α(≤50μg/L) led to increase of TROP-2 protein expression that peaks when 20μg/L TNF-αwas add?ed. High concentration of TNF-α(100, 200μg/L) result in decrease of TROP-2 protein. TROP-2 siRNA significantly down-regulated the expression of TROP-2 at both mRNA and protein levels in colon cancer HCT-116 cells. Compared with con?trol group, silencing TROP-2 by TROP-2 siRNA inhibited the migratory and invasive capability of HCT-116 cells. Wound healing rate and the number of transwell cell both decreased in siRNA group compared with those of control group ( P <0.05). Conclusion The mechanism that low concentration of TNF-α promoted HCT-116 cells migration and invasion might be through up-regulating the expression of TROP-2.

OBJECTIVETo investigate the preoperative risk factors of portal venous thrombosis (PVT) after splenectomy and gastric pericardial devascularization in patients with liver cirrhosis and portal hypertension.

METHODSClinical data was collected for 127 patients who underwent splenectomy and gastric pericardial devascularization for portal hypertension at our hospital between January 2010 and December 2012.The patient data were analyzed retrospectively according to patient status of presence or absence of PVT postoperatively.The preoperative risk factors of PVT were statistically analyzed.

RESULTSThere were no significant differences between the postoperative PVT-positive and-negative groups in regards to sex, age, receipt of emergency surgery, presence of ascites, admission to hospital for upper gastrointestinal bleeding, grade of esophageal-gastric varices, Child-Pugh classification, spleen vein diameter, liver function (as determined by levels of alanine aminotransferase, total bilirubin, direct bilirubin, albumin, globulin, cholinesterase, and gamma-glutamyltransferase), renal function (as determined by creatinine level), and coagulation function (as determined by prothrombin time, prothrombin activity degree, activated partial thromboplastin time, international normalized ratio, fibrinogen, thrombin time, and antithrombin III).However, there were significant differences between the groups for the parameters of postoperative PVT presence, upper gastric bleeding history, aspartate aminotransferase level, and blood urea nitrogen level (all P less than 0.05).Portal vein diameter and history of upper gastric bleeding were both identified as independent risk factors for PVT (P less than 0.05).Incidence of postoperative PVT was higher in patients who had portal vein diameter > 13.15 mm (cutoff value of 13.75 mm) and in patients who had a history of upper gastric bleeding.

CONCLUSIONPortal vein diameter and history of upper gastric bleeding were independent risk factors for PVT occurrence after splenectomy and gastric pericardial devascularization in patients with liver cirrhosis and portal hypertension.
