Objective:We had analyzed the attitude of science researchers in a university to promote the development of science cause in the university. Method:We had made a prevalence survey through a questionnaire. Results:Some researchers join in science cause to acquire some profits,they often change their research orientation and they aren’t willing to cooperate with each other. Conclusion:We must initiate a kind of spirit of which advantageous to collaborate,insisting,struggling and seeking the truth of science.

Objective:To find a good culture medium for embryo development in-vitro.Methods:D4 mouse embryo was cultured with carcinoma of kidney GRC-1 growth fluid and FD+20% fetal calf serum respectively in-vitro and the rate of zona-hatching,attachment and trophoblast outgrowth were compared respectively.Results:The rate of zona-hatching,attachment and trophoblast outgrowth with GRC-1 were 89.68%,86.51 %和84.92%,respectively.These were significantly higher than those of the control group ( P

For the particularity of obstetrics and gynecology disease and conventional idea of the people,clinical education of obstetrics and gynecology is very difficult.How to increase the clinical education quality of obstetrics and gynecology and how to increase the clinical'ability of medical students have become an important problem in teaching obstetrics and gynecology.In this article,we have discussed the problems and countermeasures in the teaching of obstetrics and gynecology.

Fetuin A is a kind of glycoprotein that is synthesized and secreted by the liver.It is a natural inhibitor of insulin receptor tyrosine kinase,which is involved in the formation of insulin resistance.It is closely related to the nonalcoholic fatty liver disease.This paper reviews the related research on effect of fetuin A in the occurrence and development of non-alcoholic fatty liver disease.

Objective:To explore the appearances o f digital subtraction angiograph y (DSA) and therapeutic efficacy of interventional therapy of hepatic carcinoma accompanied with arteriovenous shunting (AVS). Methods: To retro spectively analy ze clinical material of 97 patients with hepatocellular carcinoma with hepatic artery-portal vein shunting(HA-PVS) , of whom, 16 had upper gastrointestinal hemorrhage, 51 had middle to l arge amounts of ascites, and 53 had varices of esophagus and fundus gastricus . All the patients were treated with transcatheter arterial chemoembolization (TACE) or transcatheter arterial infusion chemotherapy (TAI). Shunts were embolized by lipidol i n 40 patients, by lipidol and spon-gia gelatinosa particle in 34 patients, and by coi l in 6 patients. The remaining 17 were treated only with TAI. Results:Twelve (12.4%) case s had hepatic artery-hepatic vein shunting (HA-HVS),while 32 (33%)cases had portal vein tumor thrombosis (PVTT). In 70(72.2%) patients, all shunts we r e completely closed successfully, in 15(15.5%) patients, the shunts were partly closed, and in 12(12.3%)patients, the shunts were not closed. In 12 patients, the shunts reopened in later therapy, their blood flow was smaller than before and they were closed after second embolization. In 17 patients, new shunts emerged. After TACE therapy,the tumors were smaller in 57(58.7%),bi gger in 24 (24.7%),and 16(16.5%) were the same in size before and after TACE. Ascit es disappeared in 29 patients, decreased in 18 patients and had no change in 4 pati ents. Five patients who had upper gastrointestinal hemorrhage pre-operation had n ew hemorrhage. Of the 47 patients who had diarrhea, 23 improved. In 67 alph a fetoprotein (AFP) positive patients, degree of AFP in 53 patients decreased. Eighty-one patients died and their Corresp onding author’s e-mail, renjieyang2007@163.commiddle survival period was 12.9 months. No serious dama ge to hepatic function due to the treatment was observed in most patients. Concl usion:Primary hepatic carcinoma with AVS increases difficulty of interv entional therapy,but as long as we take active and proper treating measure,we could ac quire satisfactory curative effect without serious syndrome. DSA can demonstrate the type, the site and the degree of AVS completely and directly, thus having import ant value in treating primary hepatic carcinoma and improving prognosis.

Objective Study the effect of transvaginal bitths in term pregnant women with less amniotic fluid B-mode ultrasonography suggested on neonatal and find the correct approach. Methods The maternity outcome of 166 pregnant women with less amniotic B-mode ultrasonography suggested fluid was compared with that of 187 term pregnant women with normal amniotic fluid.Results There was no significant difference on severe meconium stained amniotic fluid and the rate of neonatal asphyxin between two groups.Conclusion Transvaginal biths can be tried in term pregnant women with less amniotic fluid B-mode ultrasonography suggested under the intensive care.

Objective To compare the effects of Valsartan on blood ressure(BP)of patients with mild to moderate essential hypertension(EH).Method 64 patients with EH were randomly divided into 2 groups:Valsartan group(Enalapril 10 mg bid n=32).Treatment lasted for 8 weeks.Result Valsartan and Enalapril significantly reduce BP compared with that bdfore treatment(P< 0.05),effective rate and magnitude of decreasing BP were no significantly different between two groups(effective rate of Valsartan group was 78.1％ vs 70.0％ in Enalapril group(P>0.05).Conclusion Valsartan and enalapril have effect for decreasing the BP in EH patients.

Functional experiment plays an important role in basic theory and clinical practice. For training high-quality medical talents in medical colleges,many improvements have been made in the functional experiment teaching and certain effects have been obtained. But a comprehensive evalu-ation system was still needed. Clinical medical students of 2010 grade were taken as the appraisal objects. Assessment content,methods and standards were designed according to the basic requirements of functional experiment. Students were evaluated by ordinary performance,test papers and experiment competition. Practice showed that the system was of significant importance in improving the experi-mental teaching quality and developing students' practical ability and comprehensive quality.

Objective: To determine the effects of different levels of zinc deficiency and zinc supplementation in the early stage of pregnancy on the development of the female mice and their fetus, and the lowest toxic level was also investigated. [WT5FZ]Methods: The model of zinc deficiency (ZD) was established on Kunmin mice and the experiment included two parts. Part one: 36 female mice (14～18 g) were randomly divided into 3 groups, zinc deficient group (ZD); middle zinc group (ZM); normal zinc group (ZN). They were fed for 50 days and mated with male mice. Part two: 80 female mice (25～30 g) were randomly divided into 4 groups, zinc deficient group (ZD); zinc suppplemented group (ZS); zinc marginally deficient group (MD); normal zinc group (ZN). They were fed 25 days for depleting the zinc store in body, then mated with male mice. All the pregnant mice were killed on the 18 th day of pregnancy. The content of zinc in diet for different levels groups were: (3.0?0.5) mg/kg (ZD), 9 mg/kg (MD group), 15 mg/kg (ZM), 30 mg/kg (ZN).The mice in group ZS were fed ZD diet at first and then were changed to ZN diet at the 7 th day of pregnancy. [WT5FZ]Results: Part one: 1. The zinc content in serum was lower in ZD group (P

Using ~(125)I-labeled anti-IL-2R_? McAb, we investigated the effect of rIL-2 R_? expression . In addition to increasing the IL-2 R_? expression the actived-lymphoblasts, we found that the higher concentration of IL-2 also directly induced the IL-2 R_? expression on the resting PBL, but the peak was at the 5th day. After treated by a higher concentration of IL-2, there was a positive interrelation of time courses between the incorporation of ~3H-TdR and/or ~3H-UR and IL-2 R_? level on resting PBL. This result indicated that it was by means of inducing IL-2 R_? expression that the higher concentration IL-2 caused the proliferation of the resting PBL.
