Herald of Medicine 2016;35(8):870-874
Objective To establish a method of preparing metoprolol succinate sustained-release tablet and its content determination. Methods The formulation was optimized through the orthogonal design test by using release rate of the drug as an indicator.The different batches of metoprolol succinate sustained-release tablets were determined by HPLC. Results The tablets could release drug steadily and slowly as designed,which was similar to imported tablets. The linear range of metoprolol succinate was 10-70 μg?mL-1( r=0.999 8) . Conclusion The releasing rate of metoprolol succinate sustained-release tablet prepared in optimum condition can meet the requirement. This preparation technology is simple, the assay method is rapid, sensitive and reproducible.

2 cm). All patients received combination chemotherapy of abdomen and vein with CAP regime and TP regime after sections.Results:Total five year survival rates were 11% in epithelial ovarian carcinoma in stage Ⅲ. The 1-.3-.5-year survival rates of the cases which had less than 4 cycles of chemotherapy were lower than those ≥6 cycles, and the recurrent rates were higher than those ≥6 cycles. The 1-.3-.5-year survival rates of TP regime were higher than those of CAP regime,and the recurrent rates were lower than those CAP regime.Conclusions:There are many relationships between prognosis and residual tumor, nucmber of chemotherapy cycles or regime after resection,which influence results of recurrent ovarian cancer after repeated tumorectomy.

Objective To investigated the prevalence of obesity and metabolic syndrome (MS) and the relationship of non-alcoholic fatty liver disease (NAFLD) with MS in Hangzhou of Zhejiang province. Methods A total of 3500 subjects who were negative for hepatitis B surface antigen marker were selected to take physical examinations. Body height, body weight, blood pressure, alanine aminotransferase,fasting blood glucose,high-density lipoprotein cholesterol,and triglyeerides were recorded. B-ultrasonography of the liver and gallbladder was undertaken. Results The prevalence of MS in the NAFLD or normal control group was 25.49% and 8. 61%, respectively ( P < 0. 05 ). In multivariate logistic regression analyses, MS patients were 3. 927 times more likely to be NAFLD-related. Increased body mass index (BMI) and triglyceride were significantly associated with NAFLD among MS patients. Conclusion BMI and triglyceride level may be the main risk factors of NAFLD-related MS.

Objective To explore the impact of preoperative neoadjuvant chemotherapy on the expressions of multi-drug resistance genes in patients with cervical cancer and its relationship with the effect of chemotherapy. Methods Ninety-eight cervical cancer patients with TP regimen selected to perform preoperative chemotherapy were enrolled in the Affiliated Hospital of Guiyang Medical College between January 2010 and June 2014. Immunohistochemisty (En vision method) was used to determine the expressions of P-gP, GST-π and TopoII of the same patients before and after neoadjuvant chemotherapy and explore the relationship with the effect of chemotherapy. Results The positive expression rates of P-gp and GST-π were 71.43% and 64.29% before chemotherapy and 80.61%and 74.49%after chemotherapy, respectively. The former two had significant differences (P<0.01). The positive expression rates of TopoII was 48.98%before chemotherapy and 28.57%after chemotherapy , respectively, showing significant differences (P < 0.01). The expressions of P-gp, GST-π and TopoⅡ gene were not affected by the clinical and pathological features of cervical cancer (P > 0.05). Before neoadjuvant chemotherapy, the positive expression of GST-π in the ineffective group was statistically higher than that in the effective group (P<0.05). The positive expressions of P-gp and Topo II showed no statistical significance between the effective group and the ineffective group (P > 0.05). There was significant correlation in the expressions of P-gp, GST-π and TopoⅡ(P < 0.05) before and after neoadjuvant chemotherapy. Conclusions The expression of P-gp, GST-πand TopoⅡgene may not be affected by the clinical and pathological features of cervical cancer, but may change expressions of multi-drug resistance genes in cervical cancer by neoadjuvant chemotherapy. Monitoring their expression has a guiding significance for drug selection, prognostic judgment, and the following treatment regimen decision. The GST-π, expression level can be used as a biological parameter to predict the effect of TP regimen neoadjuvant chemotherapy.

Aim To investigate the periphery analge-sic effect of myricetin on a rat model of inflammatory pain and the mechanism. Methods Rat models of in-flammatory pain were induced by complete Freund ’ s adjuvant ( CFA) injection in left hindlimb plantar cen-ter. The thermal withdrawal latency ( TWL) was meas-ured before and after CFA or myricetin treatment. Elec-trophysiological method was used to identify the effect of myricetin on the action potential frequency and the voltage dependent potassium channel currents in small DRG neurons. Results Rats with CFA injected showed thermal hyperalgesia ( P <0. 05 ) and TWL in-creased significantly after myricetin intraperitoneally in-jected ( P <0. 05 ) . Current clamp recording showed the action potential frequency of small DRG neurons in rats was inhibited by myricetin ( P<0. 01 ) and voltage calmap recording showed the inhibitory effect of myr-icetin was enhanced by calcium depended potassium channel currents ( P<0. 05 ) . Conclusion Myricetin exerts periphery analgesic effect by enhancing calcium depended potassium channel currents and inhibiting excitability of small neurons of dorsal root ganglion.

Objective To know the relationship between the uterine fibroid symptom severity and the quality of life andthe correlation among all the subscales of the quality of life base through analysis of the questionnaires of the uterine fibroids health-related quality of life.Methods Retrospectively analyze the UFS-QOL subscales and SF-36 subscales of the 302 women with uterine fibroids who underwent ultrasound ablation in the high intensity focused ultrasound center of the First Affiliated Hospital of Chongqing Medical University in 2013.Results The Cronbach'sa of the UFS-QOL symptom severity subscale and the HRQL subscales were 0.794 and 0.953,reflecting adequate internal consistency.Except the sexual function field,the symptomatic group reported significantly greater symptom severity and worse health-related quality of life(HRQL) than the asymptomatic group(P< 0.05).Spearman's correlations between the symptom severity subscale and each HRQL subscales were moderately in the asymptomatic group,there was a linear positive correlation between the UFS-QOL subscales of activities,energy/mood and control(P< 0.05).In the symptomatic group,there was a linear negative correlation between the symptom severity subscale and the UFS-QOL subscales of concern,activities,energy/mood(P<0.05),and there was a linear positive correlation between the UFS-QOL subscale of activities and the UFS-QOL subscales of concern,energy/mood.Conclusion Uterine fibroids related symptoms have an impact on the quality of life in women with uterine fibroids,and the assessments among the subscales of the quality of life influence each other.

AIM: To investigate lipoprotein lipase gene HindⅢ polymorphism and its relationship with serum lipids and apolipoprotein, serum HDL subclasses in patients with hyperlipoidemia. METHODS: Lipoprotein lipase gene HindⅢ polymorphism was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The subclasses of serum HDL in 152 hyperlipoidemia patients and 128 healthy subjects were determined by two-dimensional gel electrophoresis conjunction with immunodetection method. RESULTS: H+H+ genotype and allele H+ in hyperlipoidemia and control groups were both the highest. In hyperlipidemia group, H+H+ genotypes tended to be higher than that in control group, while H+H- and H-H- genotypes were significantly lower (P
