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 explore the application value of hysteroscopy in recurrent implantation failure ,and discuss what was the best time to transfer embryos after the operation .Methods The patients who had undergone two or more failed IVF-ET cycles were separated into two groups .The patients of group A ( n=210) received hysteroscopy , and the patients of group B ( n=71) did not receive hysteroscopy evaluation .Intrauterine lesions diagnosis were trea-ted during the procedure .Patients without intrauterine pathologies were given slight curettage .The recurrent IVF-ET were performed after the procedure .Then we analyzed the clinical pregnancy rate of the two groups and determined the best time to transfer embryos after the operation.Results In group A,57 patients were pregnant.In group B, 8 patients were pregnant .There was a significant difference in the clinical pregnancy rates between the two groups (χ2 =7.52,P<0.01).In the pregnant patients of group A ,about 94.7%were pregnant in 6 months after hysterosco-py.Conclusion The patients with recurrent IVF -ET transfer failure should be evaluated prior to commencing IVF-ET cycle to improve the clinical pregnancy rate .It is better to transfer embryos within 6 months after hysteroscopy operation.

Objective To construct an eukaryotic expression vetor of ring finger protein 6 (RNF6)and to investigate its ubiqu-itylation on insulin receptor substrate-1(IRS-1).Methods Human RNF6 coding sequence was amplified by polymerase chain reac-tion (PCR)method with human cDNA as template.The pcDNA3.1-CHA-RNF6 was constructed with routine molecular methods and transfected into hepatocarcinoma cell HepG2.Relative quantification of IRS-1 mRNA was preformed by real-time reverse tran-scription PCR.Western blot was applied to detect the expression levels of IRS-1.Results 48 h after the plasmid carring RNF6 gene transfected HepG2 cells,the mRNA level of ISR-1 gene reduced to 69% of control group.The expression of IRS-1 was markedly lower than control group (P <0.01).Conclusion The expression of IRS-1 is markedly down-regulated in HepG2 and enhancement of the ubiquitylation level of IRS-1 contribute to the disorder in insulin signal transferring.

Objective To establish a TaqMan probe-based real-time fluorescent quantitative PCR ( real-time PCR) for the quantitative and rapid detection of viral reservoir in peripheral blood mononuclear cells (PBMCs) isolated from rhesus monkeys with simian immunodeficiency virus (SIV) infection and to evaluate its preliminary application. Methods A pair of primers and one TaqMan probe were designed ac-cording to the conserved sequence of SIVmac239 strain for real-time PCR amplification. A length of 2 090 bp of nucleotide fragment was digested from the plasmid p239SpSp5 containing 5′-end long segments of SIV-mac239 strain by restriction enzymes EcoRⅠand SpeⅠ. The standards used for quantitative detection of SIV DNA in peripheral blood samples were prepared by a 10-fold serial dilution and used for graphing the stand-ard curve. The numbers of SIV DNA ( copies per 106 PBMCs) in rhesus monkeys during acute and chronic phases of SIVmac239 infection were determined and the virological characteristics of SIV DNA at different phages of infection were analyzed. Results A linear positive correlation between cycle threshold ( Ct) val-ues and concentrations (10 copies/μl to 109 copies/μl) of the standards was found. High levels of SIV DNA were monitored in SIV-infected monkeys 14 to 22 days after acute infection. The levels of SIV DNA in the acute phase of infection were about 1 to 2 logs higher than those in the chronic phase of infection. The num-bers of SIV DNA ( copies per 106 PBMCs) were 1 log lower than the SIV viral load in peripheral blood of the same monkey. The ratios of SIV DNA load to SIV RNA load ( DNA/RNA) in chronic phase of infection were higher than those in the acute phase. Conclusion The established TaqMan probe-based real-time fluorescent quantitative PCR was a highly sensitive and specific assay for the detection of SIV DNA with an advantage of wide linear range. It could be used for the quantitative evaluation of latent reservoirs of SIV.

AIM To observe the effects of the combination of heparinoid, aspirin and losartan on the experimental vascular intima hyperplasia induced by squeezing carotid artery in rats. METHODS Rats except the normal control group were under operation after two days oral administration once a day. At the second hour after injury, blood coagulation time(CT), time of arterial thrombus formation by electrical stimulus(ATFTES) and the level of TXB_2 in plasma were measured. At the fourteenth day after the surgery, the following indexes were examined: intima/media ratio, intima area ratio, PDGF-B and PCNA immunohistochemistry in carotid artery. RESULTS CT, TATFES increased and the level of TXB_2 decreased in the groups of Hep, Asp and Hep+Asp. The PDGF-B content, the positive ratio of PCNA and the inti- ma/media ratio also decreased in the groups of Hep, Asp, Los, Hep+Asp, Hep+Los and Asp+Los. Compared with single drug or two drugs combination, PDGF-B, positive ratio of PCNA, intima/media ratio and intima area ratio decreased significantly in the group of three drugs combination( P

Objective:To observe the influence of schisandrone on the levels of IL-1? and iNOS mRNA in the hippocampus of rats with Alzheimer-like disease(AD) and to investigate the probable prevention and therapy effect of schisandrone on AD. Methods: Totally 30 male SD rats, 8-12 weeks old, weighing 250-300 g, were randomly divided into 3 groups: blank control group,AD model group and schisandrone intervention group(n=10). The animal model of AD was established by 10 mmol/L amyloid-beta protein(A? 25-35 ) 5 ?l stereotactic injection into lateral cerebral ventricle of rats and the rats of schisandrone intervention group were administrated with corn oil with 1 mmol/L schisandrone. And then the levels of IL-1? and iNOS mRNA in the hippocampus were detected by RT-PCR. Results: The levels of IL-1? and iNOS mRNA in the hippocampus of rats with Alzheimer-like disease (0.333 7?0.122 3, 0.266 6?0.088 5) decreased obviously after administration of schisandrone (0.969 3?0.153 9, 0.666 0?0.121 1)(P

Aim To study the oxygen free radical scavenging activities and antilipid peroxidation of nicotinic acid. Methods High lipid models of quail were induced by high fat diet. Five groups were divided, namely control group, high lipid group, NA group(150 mg?kg-1 and 75 mg?kg-1), and Vit E group (100 mg?kg-1). The contents of TC,TG,MDA and activities of SOD were examined for 3 times in the plasma and liver after administering NA for 9 weeks. Results The results showed the increase of TC,TG and MDA contents and decrease of SOD activities in high lipid groups by 3 weeks high fat diet. After administering NA for 3 weeks, NA reduced TC,TG and MDA contents and increased SOD activities, revealing the relationship to dose-dependence. Conclusion NA is most likely to possess the capabilities of anti-oxygen free radicals and anti-lipoperoxidation to hyperlipodemia quail.
