Hyperuricemia mice model was established with uricase inhibitor (potassium oxonate) and uric acids in serum were observed. Polydatin (5, 10, 20 mg · kg(-1)) and benzbromarone (16.7 mg · kg(-1)) were given ig for 7 d in mice. Kidney tissues were used to detect gene contents ofurate anion transporter 1 (URAT1), organic anion transporter 1 (OAT1) and organic anion transporter 3 (OAT3) by real-time-PCR. The results showed that polydatin and benzbromarone can significantly reduce uric acid in blood of hyperuricemia mice (P < 0.05), compared with the model group. URAT1, OAT1 and OAT3 contents of the kidney in hyperuricemia mice changed significantly (P < 0.05), compared with the blank group. Polydatin can significantly inhibit the changing trends in these genes induced by potassium oxonate in a dose-dependent manner, the difference was significant (P < 0.05), compared with the model group. Those indicated that polysatin could reduce the level of the serum uric acid through promoting uric acid excretion.

Purpose:To investigate the effect of CD40 ligandization on breast cancer cell line and endothelial vein cell line.Methods:The expression of CD40 and its ligand on breast cancer cell line(M231),EVC cell line,fresh clinic breast cancer cell were determined by indirect immunofluorescence assay with flow cytometry(FCM) analysis.Then M231 cells cultured with CD40 agonsitic monoclone antibody,adriamycin alone or in combinations for 72 hours and proliferation of M231cells was determined by MTT assay.FCM was employed to study the cells' death or apopotosis with Annexin V PI assay.Results:M231 and ECV cell line and fresh clinic breast cancer cell are highly expressed CD40 but no CD40L.CD40 ligandization can not only inhibit the proliferation of M231 cell line but also inhibit ECV cell line by promoting the death or apoptosis of these cells.Combined CD40 agonsitic monoclone antibody with adriamycin may obviously inhibit proliferation of M231 and ECV cell line.Conclusions:CD40 ligandization may have double therapeutic effect to breast cancer: inhibit the proliferation of breast cancer cell and inhibit tumor angiogenesis by inhibiting vascular endothelial cell.

OBJECTIVE:To study the relieving cough and eliminating phlegm effects of stemoninine combined with mogrosideⅤ on mice,and select its optimal ratio. METHODS:70 mice were selected in each experiment and randomly divided into 7 groups,namely solvent group(normal saline), codeine(15 mg/kg)or ambroxol(30 mg/kg)group(positive control),stemoni-nine group(30 mg/kg),mogroside Ⅴ group(30 mg/kg),stemoninine-mogroside Ⅴ combination group(30 mg/kg)with mass ra-tio of 2:1,1:1,1:2,ig,once a day. Ammonia-induced cough experiment(positive drug was codeine)and tracheal phenol red ex-cretion experiment(positive drug was ambroxol)were respectively conducted. Using cough latent period,cough times and volume of tracheal phenol red excretion as indexes,the antitussive and expectorant effects of drug in each group were compared. RE-SULTS:Compared with solvent group,cough latent period was obviously shortened,cough times was obviously reduced,volume of tracheal phenol red excretion was obviously increased in each administration group(P<0.05 or P<0.01). Compared with mogro-side Ⅴ group,cough latent period was obviously shortened,cough times was obviously reduced in stemoninine-mogroside Ⅴgroup with different mass ratios(P<0.05),and 2:1,1:1 groups showed the best effects. Compared with stemoninine group,vol-ume of tracheal phenol red excretion was obviously increased in stemoninine-mogroside Ⅴ group with different mass ratios (P<0.05),and 1:1,1:2 groups showed the best effects. CONCLUSIONS:The combination of temoninine and mogroside Ⅴ shows synergistic effects on relieving cough and eliminating phlegm,stemoninine-mogrosideⅤmass ratio of 2:1,1:1 can be used as pre-ferred combination of reference.

Objective To look into the effects of community intervention measures on blood pressure and hypertension control of the population.Methods Two geographic separated urban communities with the population about 50 000 each were selected as either intervention or control communities in Beijing in 1996.In the intervention community,the primary and secondary prevention on high blood pressure were carried out.And the morbidity and mortality of stroke in both intervention and control populations were monitored.A baseline survey and evaluation re-survey were respectively conducted in 1997 and 2000 covering both intervention and control communities with a cluster random sample of about 800 persons each.Results In the baseline survey,there were no difference between intervention and control communities in six of seven variables including systolic blood pressure(SBP),diastolic blood pressure(DBP),prevalence of hypertension,rate of awareness,therapy,control with SBP 140 and DBP

Congenital bile duct cysts, which is a kind of malformation of bile duct, will lead to the inflammation in the bile duct system for a long time. Therefore, patients with cholelithiasis and cyst canceration have a risk. Surgical operation is the only treatment option for the congenital bile duct cysts patients. Resection of the cysts and complete " biliary-pancreatic duct shunt" are the key points of the standardized treatment of congenital bile duct cysts. The non-standard surgical treatment will bring the postoperative complications such as the stricture of choledochojejunostomy, the remnant cysts and even the canceration of cysts, which will seriously affect the quality of life and threaten the health of patients. Based on the retrospective study of congenital bile duct cysts patients in Eastern Hepatobiliary Hospital, the author proposed a new classification system according to the pathological and anatomical characteristics of congenital bile duct cysts. The congenital bile duct cysts can be divided into three regions and five types, i. e. localized type and diffuse type of extrahepatic bile duct cysts of hilar, trunk and terminal type; central type; and intrahepatic bile duct cysts of limited and diffuse type. It is our hope that this typing system will accurately guide the design and implementation of surgical treatment plans for congenital bile duct cysts and reduce the risk of long-term postoperative complications for patients.

Objective Risk factor of radial and horizontal tear for posterior horn of medial meniscus is analyzed in present study.Methods A total of 390 patients diagnosed with medial meniscus tear received during January 2011 to December 2012 were of retrospective analysis.94 cases with radial tear of medial meniscus posterior horn and 95 horizontal cases were chosen as research objects.Age,gender,duration of symptoms,body weight index,trauma history,posterior slop of tibia plateau,knee valgus angle and Outerbridge cartilage classification of patients with radial or horizontal tear were recorded and analyzed.Multifactor unconditioned Logistic regression analysis was employed to analyze risk factor of meniscus radial tear.Results Significant difference could be spotted in the analysis of gender (x2=9.059,P=0.003),body weight index (t=2.549,P=0.012),knee valgus angle (t=-5.609,P=0.000) and Outerbridge cartilage classification (x2=42.300,P=0.000) between patients with radial or horizontal tear.Meanwhile,no significant difference could be spotted in the analysis of trauma history (x2=0.368,P=0.544),posterior slop of tibia plateau (x2=1.021,P=0.312),age (t=-1.228,P=0.221) and symptom duration (t=0.272,P=0.786).According to the results of multi-factor analysis,valgus angle (OR=12.581,P=0.001),age (OR=0.875,P=0.026) and Outerbridge cartilage classification (OR=33.790,P=0.000; OR=15.558,P=0.000; OR=39.891,P=0.000; OR=91.041,P=0.000) were risk factors of meniscus radial tear.Conclusion High incidence of posterior horn of medial meniscus tear was found in patients with senile osteoarthritis.The incidence of radial tear of medial meniscus posterior horn in elderly patients with knee varus or serious articular cartilage was higher than that of horizontal tear.

OBJECTIVE:To systematically review the difference of phlebitis induced by Alprostadil injection with different ad-ministration routes,and to provide evidence-based reference for clinical rational use. METHODS:Retrieved from PubMed,EM-Base,Cochrane Library,CBM,CJFD,VIP and Wanfang database,RCTs about phlebitis induced by Alprostadil injection with dif-ferent administration routes were collected. Meta-analysis was conducted by Rev Man 5.2 statistical software after literature screen-ing,data extraction and quality evaluation according to Cochrane System Evaluator's Manual 5.1.0. RESULTS:A total of 20 RCTs were included,involving 2562 patients. The results of Meta-analysis showed that the incidence of phlebitis induced by intravenous injection was significantly higher than that induced by intravenous dripping [OR=4.11,95%CI(1.59,10.67),P=0.004] and intrave-nous pump [OR=3.50,95%CI(1.50,8.16),P=0.004]. The incidence of phlebitis induced by general apparatus infusion was signifi-cantly higher than that induced by fine filtering infusion [OR=0.03,95%CI(0.01,0.08),P<0.001],with statistical significance. CONCLUSIONS:The incidence of phlebitis induced by low-concentration of Alprostadil injection or fine filtering infusion is low-er,and that of intravenous injection is higher.

Objective To improve the understanding to transposition of the great arteries with posterior aorta and decrease the clinic misdiagnosis by summarizing their echocardiography features . Methods Echocardiography images were retrospectively reviewed for 7 cases with transposition of the great arteries with posterior aorta who diagnosed in Anzhen Hospital ,and their echocardiography features were summarized .Results In 7 patients ,5 patients had operation ,including 3 for arterial switch operation ,1 for right GLEEN ,1 for right GLEEN and Fortan surgery ,and 2 patients were lost to follow‐up .The echocardiography characters:① Artery short view showed aorta and pulmonary artery existed the half‐surrounding relationship .The aorta was situated posteriorly and the pulmonary artery anteriorly .②Multiple views showed aorta was completely and mostly arised from the right ventricle ,while the pulmonary artery was came off the left ventricle .③ Ventricular septal defects were presented in all cases and aorta could ride the defect of ventricular septal .④ In most cases ,fibrous continuity between the aortic and mitral valve through a ventricular septal defect was found and there was no conus under the aorta .⑤ Some cases could combine the different degree stenosis of the outflow tract of subpulmonary valve and pulmonary valve . Conclusions The connection relationship between two arteries and ventricles can displayed clearly on the long axis view of double outflow tracts of two ventricles under xiphoid process .The acoustic window under the xiphoid process is the key for diagnosis and differential diagnosis of the disease .

Objective To explore the mediation role of university graduates' core self-evaluation played between perfectionism and job-selecting anxiety.Methods 200 university graduates were investigated by Chinese frost multidimensional perfectionism questionnaires,core self-evaluation scale and self-rating anxiety scale with convenience sampling method.Results ①Job-selecting anxiety had no distinct differences in gender,residence and the aspects of only-child(P＞0.05),but in different subjects,it was different(science and technology(1.79±0.49),culture and history(3.21±0.50),t=-4.38,P＜0.01).② University graduates' positive perfectionism was positively correlated with core self-evaluation (r=0.31,P＜ 0.01),while negatively correlated with job-selecting anxiety (r=-0.35,P＜0.01).University graduates' negative perfectionism was negatively correlated with core self-evaluation(r =-0.35,P＜ 0.01),while positively correlated with job-selecting anxiety (r =0.42,P＜ 0.01).Simultaneously core self-evaluation was negatively correlated with job-selecting anxiety (r=-0.46,P＜ 0.01).③ Core self-evaluation played a part of the intermediary role between negative perfectionism and job-selecting anxiety.The mediating effect was 30.0％ of the total effect.Core self-evaluation played a part of the intermediary role between positive perfectionism and job-selecting anxiety.The mediating effect was 34.5％ of the total effect.Conclusion Perfectionism as a personality trait can calculate the level of job-selecting anxiety.Core self-evaluation plays a part of the intermediary role between perfectionism and job-selecting anxiety.It is helpful to the working tactics of university graduates.

Objective To improve the prenatal echocardiographic diagnostic accuracy for fetus with isolated mirror-image right aortic arch which combined with vascular ring by analyzing and accumulating its echocardiographic features.Methods Echocardiographic signs were analyzed retrospectively and fetal echocardiographic features were accumulated in 16 cases with prenatal diagnosis of isolated mirror-image right aortic arch with left-side ductus arteriosus which formed vascular ring between January 2014 and February 2016.All cases were confirmed by neonatal echocardiography.Results The fetal echocardiography characters:① In 3-vessel and trachea view,fetal right aortic arch was demonstrated a Ushaped appearance of the great vessels,the right arm of the ‘ U’ represented the aortic arch and its left branch with ductal continuation.② In 3-vessel and trachea view or upper axial mediastinal transverse view,left innominate artery passed straightly to the left of the trachea.Left innominate artery and right-side ductus arteriosus were overlapped and the distance of two vessels was very close.③ In double arch view and longitudinal view for ductus,Left innominate artery did not connect to descending aorta or ductus arteriosus and did not involve in the formation of vascular ring.④ Color Doppler played an important role in diagnosis of this disease.Power Doppler or high-definition imaging easily showed color overflow and wrongly displayed the crossed relationship of left innominate artery with descending aorta as the anatomical connection,and caused the misdiagnosis of this disease as double aortic arch.Conclusions Isolated mirrorimage right aortic arch with vascular ring is not rare in the fetal period.Because ductus arteriosus is large and patent during the prenatal period,it is easily mistaken for the crossed relationship of left innominate artery with descending aorta as the anatomical connection and finally misdiagnoses this anomaly as double aortic arch.The keys to accurate diagnosis of the disease are clearly visualization of the innominate artery and its relationship with descending aorta and ductus arteriosus by scanning different views.
