OBJECTIVE:To provide reference for improving the quality of clinical pharmacy undergraduates in our university. METHODS:Considering about the practice problems of clinical pharmacy undergraduates in our university,pilot reform was con-ducted in the First Affiliated Hospital of our university in respects of teacher arrangement,department rotation assignment,assess-ment method. RESULTS:For new practice mode,in term of teacher arrangement,when the students were practicing in clinical pharmacy department,they were taught by clinical doctors and pharmacists;teacher training should be strengthened,and a variety of teaching methods was carried out. In term of department rotation assignment,to shorten the practice time of basic pharmacy de-partment,and increase the clinical pharmacy practice department and practice time;to integrate the content of clinical medicine and clinical pharmacy practice,and select clinical medical departments equipped with clinical pharmacists to practice. In term of assess-ment method,there were 3 aspects including clinical pharmacy practice skills assessment,drug-related theory examination and ba-sic situation assessment during internship. CONCLUSIONS:The new practice mode focuses on clinical pharmacy application skills training and students practical skills assessment,contributes to cultivate students'thinking of rational drug use and improves clini-cal practice skill of students. It is suitable for clinical pharmacy undergraduate internship of our university.

A cross-sectional study of 92 women with polycystic ovary syndrome(PCOS) was performed.The patients were composed of 4 groups according to the Rotterdam criteria and were also divided into 2 groups according to body mass index and divided into 2 groups according to insulin-releasing test.Anthropometric measurements were recorded,and hormonal profile was assessed by measuring FSH,LH,prolactin,and testosterone.The metabolic profile was investigated by measuring glucose and insulin level during oral glucose tolerance test (OGTT),then calculating the homeostasis model assessment (HOMA).Serum lipid levels,including total cholesterol,triglycerides,high-density lipoprotein-cholesterol,and low-density lipoprotein-cholesterol were determirned.The result suggests that the classification according to the revised 2003 Rotterdam consensus on diagnosis does not reflect dyslipidemia in PCOS.Dyslipidemia in hyperinsulinemic group and obesity group were more severe than that in non-hyperinsulinemic group and non-obese group ; this finding needs our attention in early treatment and prevention of late complications of PCOS.

ObjectiveTo study the effects and molecular mechanisms of Shuanglong Pill on angiogenesis of ischemic myocardium. Methods63 Wistar rats were ligated left anterior descending branch to be made into models of acute myocardial infarction(AMI).All rats were randomly divided into large-dosage group of Shuanglong Pill(LDG),small-dosage group of Shuanglong Pill(SDG),The control of acute MI(MIC).Other 11 rats were set as normal control(NC).Rats in every group had been treated half for 2 weeks and half for 4 weeks. New vessels' quantity in ischemic myocardium of acute MI rats were detected by immunohistochemistry double steps assay;the expressions of vessel endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) on ischemic myocardium were detected by immunohistochemistry SP assay;the expressions of VEGF mRNA and bFGF mRNA on ischemic myocardium were detected by reverse transcription polymerase chain reaction(RT-PCR) assay.ResultsThere were more new capillaries on ischemic myocardium of LDG, SDG compared with that in MIC at every stage,moreover,there was significantly increase at the end of 4 weeks compared with that at 2 weeks.At the end of 2 weeks, the expression of VEGF in LDG were significantly elevated compared with that in MIC; and the expression of bFGF in LDG were significantly elevated compared with that in SDG and MIC.Whereas the expression of VEGF in LDG were significantly decreased at the end of 4 weeks compared with 2 weeks. There were significant differences of above comparison (P<0.05-0.01).At every stage the expression of VEGF mRNA in LDG, SDG were significantly elevated compared with that in MIC; but its expression was significantly decreased at the end of 4 weeks compared with that 2 weeks. The expression of bFGF mRNA was significantly elevated in LDC at the end of 2 weeks compared with that in other groups.ConclusionsShuanglong Pill could promote angiogenesis in ischemic myocardium,application of large dose of Shuanglong Pill could significantly upregulate the expression of VEGF, bFGF, VEGF mRNA and bFGF mRNA.

To investigate the relationship between plasma level of homocysteine(Hcy) and the methylenetetrahydrofolate reductase ( MTHFR ) gene polyroorphism with non-alcoholic fatty liver in patients with type 2 diabetes mellitus (T2DM). Methods In a case-control study, plasma levels of Hcy, folic acid (FA), vitamin B12 (VitB12), glycosylated hemoglobin Alc (HbAlc), fasting blood glucose (FBG), total cholesterol and triglyceride were measured in 159 T2DM patients with and without non-alcoholic fatty liver ( NAFL), as well as 52 normal controls. Mutation of the C677T of MTHFR gene was determined by polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) for all of them. Results Patients of T2DM both without NAFL (96 case) and with NAFL had higher prevalence of hyperhomocysteinemia (Hhcy) (49% and 21%, respectively ) than normal controls did (4 cases, 8% ) (P<0.05), while patients of T2DM with NAFL had higher prevalence of Hhcy than those without it did (P <0. 05). Plasma level of Hey positively correlated to genotype frequency of the MTHFR gene, plasma 0levels of HbAlc and FBG in patients of T2DM, with coefficients of correlation of 0.248, 0.423 and 0.242, respectively (P < 0.05). Results of multiple logistic regression analysis showed that course of the disease, body mass index, plasma levels of FBG and Hcy all were independent risk factors for non-alcoholic fatty liver in patients with T2DM. Conclusions Hhey was an independent risk for non-alcoholic fatty liver and plasma level of Hey was influenced by frequency of the TT genotype of the MTHFR gene, plasma levels of FA and VitB12, as well as metabolic disturbance in patients with T2DM.

Objective To study the anatomic landmarks of recurrent laryngeal nerve (RLN) in minimally invasive video-assisted thyroidectomy (MIVAT), and to evaluate the operative skills to avoid nerve injury. Methods 106 patients were enrolled in the study dated between August 2008 and August 2010, in which 8 patients were converted to the conventional thyroidectomy. Intraoperative anatomic landmarks for location of RLN were the gap between trachea and carotid artery (GTC), as well as the middle and posterior portion of tracheal wall. Results 98 RLN were at risk, and 97 (98.98 %) nerves were recognized by means of two landmarks. 1 nerve failed to locate which was non-recurrent laryngeal nerve. Temporary RLN paralysis happened to 1 nerve(1.02 %), and no permanent RLN paralysis appeared. Conclusion GTC combined with middle and posterior portion of tracheal wall are safe and effective anatomic landmarks to locate RLN in MIVAT.
