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.

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.

Reference materials containing mixed degradation products of amoxicillin and ampicillin were developed after optimization of preparation processes. The target impurities were obtained by controlled stress testing, and each major component was identified with HPLC-MS and compared with single traceable reference standard each. The developed reference materials were applied to system suitability test for verifying HPLC system performed in accordance with set forth in China Pharmacopeia and identification of major impurities in samples based on retention and spectra information, which have advantages over the methods put forth in foreign pharmacopoeias. The development and application of the reference materials offer an effective way for rapid identification of impurities in chromatograms, and provide references for analyzing source of impurities and evaluation of drug quality.

To understand molecular modules related to polyunsaturated fatty acids (PUFA) synthesis and eventually produce PUFA at high efficiency, we developed a protein complex analysis technology in Synechocystis sp. PCC 6803, and applied it to identify possible partner proteins interacting with the key enzymes that catalyze PUFA biosynthesis. We first constructed a recombinant expression of protein of slr1609 encoding the fatty acid activation enzyme, by fusing 3xFLAG tag with the target protein. Then we verified its expression by Western blotting targeting 3xFLAG tag. To maximize purification of Slr1609 protein complex, we optimized the protein expression conditions of Slr1609 in Synechocystis in a 5 L fermenter by monitoring its gene expression using RT-qPCR. The purification of the Slr1609 protein complexes was demonstrated by a Native-PAGE analysis. Finally, LC-MS/MS proteomic analysis allowed identification of the possible partner proteins interacting with Slr1609.

CYP2D6 is one of the cytochrome P450 isozymes which are involved in the metabolism of various drugs with wide use. Polymorphism at the CYP2D6 locus is one of the most widely known causes for pharmacogenetic variability in humans beings. This review focuses on the importance of CYP2D6 polymorphism in the metabolism of tamoxifen, relationships between the genetic polymorphism and prognosis of patients who have underwent endocrine therapy, and evidences indicating that CYP2D6 may be used as a predictive marker for choosing optimal endocrine therapy for patients with breast cancer.

Objective To assess circulating miRNAs’diagnosis value of breast cancer.Methods Conducted PubMed,Embase, the Cochrane Library,CNKI,cqvip,and wangfang database search in any language before June 2014.A total of 12 publica-tions were included in the meta-analysis.Then,the meta-analysis was performed using Meta-Disc 1.4.Meanwhile,the diag-nostic sensitivity,specitivity,positive likelyhood ratio,negative likelyhood ratio and diagnostic odds ratio were pooled by ran-dom-effects models.And the overall diagnostic performance was estimated by summary receiver operating characteristic curves (sROC)approaches.Stata12.0 was used to evaluated the publication bias.Results The pooled sensitivity was 80%(95%CI 0.77~0.82),specificity was 78% (95%CI 0.75~0.81);positive likelihood ratio was 4.09 (95%CI 2.80~5.99), negative likelihood ratio was 0.22 (95%CI 0.15~0.31),diagnostic odds rations was 20.64 (95%CI 10.24~41.62).The AUC for circulating miRNAs was 0.89 with Q value of 0.82.Publication bias was observed in existing literatures.Conclu-sion Circulating miRNAs is a potential biomarker in the diagnosis of breast cancer.

Survivin variants specific real time quantitative RT-PCR was developed to analyze their expression in 53 paired cancer and para-cancerous tissues, and the expression of the wild-type survivin protein was detected by immunohistochemistry. The results showed that survivin mRNA and protein were expressed in gastric cancer and para-cancerous tissues. The survivin-2B was dominantly expressed in para-cancerous tissues, whereas the survivin-DeltaEx3 was more frequently detected in cancer tissues. The positive rate of survivin-2a was 100% in both cancer and para-cancerous tissues, but its relative transcript expression level was not significantly increased in cancer tissues in comparison with para-cancerous tissues. The correlation analysis revealed that the expression of survivin-2a mRNA was significantly associated with that of total survivin (r (s)=0.4178, P=0.0018), whereas inversely to that of survivin-DeltaEX3 (r (s)=-0.4506, P=0.0007). It was suggested that survivin-2a may act as an antagonist of survivin-DeltaEX3. The balance between antiapoptotic survivin iso-forms and nonantiapoptotic ones may play an important role in tumorigenesis and tumor progression. Promising value is hinted to analyze survivin and its variants in tumor early diagnosis and distinguishing malignant tumors from benign ones.
