OBJECTIVETo observe the clinical effect of Shugan Yiyang Capsules combined with sertraline in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 192 PE patients to receive sertraline hydrochloride 50 mg qd (control group, n = 96) or sertraline hydrochloride 50 mg qd plus Shugan Yiyang Capsules at the dose of 4 capsules tid ( combination therapy group, n = 96) , both for 6 weeks. We compared the intravaginal ejaculatory latency time (IELT) and Chinese Index of Premature Ejaculation ( CIPE) scores between the two groups of patients before and after medication and at 6 weeks after drug withdrawal.

RESULTSCompared with the baseline, the IELT was significantly increased after 6 weeks of medication in the combination therapy group ([1.41 ± 0.53] vs [6.69 ± 3.56] min, P < 0.05) and the control group ([1.43 ± 0.48] vs [5.37 ± 2.91] min, P < 0.05), and so was the CIPE score in the former (9. 80 ± 2.06 vs 21.62 ± 4.76, P < 0.05) and the latter group ([9.41 ± 1.97] vs [20.85 ± 4.83] , P < 0.05). In comparison with the pre-medication indexes, the IELT ([3.77 ± 1.63] min) and CIPE score (16.92 ± 3.37) of the combined therapy group were remarkably improved at 6 weeks after drug withdrawal (P < 0.05), but not those of the control ([1.19 ± 1.34] min and 10.59 ± 2.38, P > 0.05).

CONCLUSIONShugan Yiyang Capsules combined with sertraline have a definite and lasting effect on premature ejaculation.

Objective To investigate the calculation method and its inlfuencing factors of Z scores in the aortic root diameters measured by echocardiography in children. Methods A total of 105 children with median age 19 months, who came to Shenzhen Children′s Hospital from March 2012 to October 2012 were included. The diameters of aortic ring (ARD) and aortic sinus (ASD) were measured by two dimension echocardiography, Z scores of ARD and ASD were calculated using two different normal reference values regression equation and mean square error derived from Shenzhen children′s hospital (C method) and Pettersen et al (P method). The regression equation from C method and body surface area (BSA) formula from P method were adopted to calculate Z scores of ARD and ASD (ZH method). The Z results of ARD and ASD calculated by those three methods were compared and were analyzed for their normality probability distributions. Results Z scores of ARD and ASD derived from C method were all showed as normal distribution (P=0.067 and 0.650). Z scores of ARD and ASD derived from P method were all showed as normal distribution (P=0.208 and 0.970). Z score of ARD derived from ZH method was showed as non-normal distribution (P=0.027), but Z score of ASD was normal distribution (P=0.430). There were no significant differences in ARD-Z calculated by C method (0.41±0.89), P method (0.23±0.85) and ZH method (0.36±0.94) (F=1.117, P=0.309). There were signiifcant differences in the Z scores of ASD calculated by C method (0.38±0.89), P method (0.58±0.71) and ZH method (0.36±0.84) (F=5.443, P=0.005). Z scores of ARD (r=0.917, P=0.000) and ASD (r=0.900, P=0.000) calculated by C method correlated well with that by P method. Conclusions Calculation method of BSA and normal reference values regression equation were the main influencing factors of Z score value in quantifying children aortic root diameters by echocardiography. For the clinical applications. The normal reference value should be used which is suitable for the Chinese children.

OBJECTIVE To identify the antibiotic resistance,homology and the carbapenemases determinants of imipenem-resistant strains of Acinetobacter baumannii isolated from elderly in the Zhejiang Hospital.METHODS All 142 strains of A.baumannii were isolated from Zhejiang Hospital through Jan 2005 to Jan 2007.K-B method was used to screen imipenem-resistant strains.The MICs of imipenem-resistant strains to 14 antimicrobial agents were determined by agar dilution method.The homology of these isolates was analyzed by pulse-field gel electrophoresis(PFGE).The coding genes of carbapenamases and the gene environments were investigated by PCR,clone,and sequencing.RESULTS Ninety-seven strains of imipenem-resistant A.baumannii were isolated from 142 strains.All of the strains of carbapenem resistant A.baumannii belonged to 4 epidemic PFGE-clones.Ninety carbapenem resistant strains contained OXA-23-like carbapenemase gene and 91 isolates were positive for OXA-51-like gene. OXA-23-like gene of 86 strains was just on the down-stream of insert sequence ISAba1.OXA-51-like gene of 6 strains had an ISAba1 sequence just on the up-stream.CONCLUSIONS All imipenem-resistant strains of A.baumannii are pan-resistant isolates.Clone dissemination is the most important style of strains spread.No OXA-24-like,OXA-58like,IMP-like,and VIM-like gene are detected.OXA-23-like and OXA-51-like gene are the most popular carbapenemases coding genes of these strains in the Zhejiang Hospital.ISAba1 has close relationship with OXA type carbapenemases genes in Zhejiang Hospital.

Objective · To observe effect of 17β estrodial (17β E2) with different concentrations on C type natriuretic peptide (CNP), insulin like growth factor 1 (IGF1), and natriuretic peptide receptor B (NPR-B) expression and proliferation of growth plate chondrocytes of rats in vitro. Methods · Eight Wistar rats were sacrificed and their epiphyseal cartilages of the upper tibias were separated to obtain chondrocytes on the 14th day after birth. Then chondrocytes were cultured with 17β E2 in different concentrations (10-4、10-6、10-8、10-10 and 10-12 mol/L) for 48 h, while control group was cultured without 17β E2. CCK8 method, ELISA and qRT-PCR were used to analyze the proliferation of chondrocytes, the levels of CNP and IGF1 in culture medium and mRNA levels of CNP, NPR-B and IGF1, respectively. Results · 17β E2 in different concentrations affected the proliferation of growth plate chondrocytes significantly. When the concentration of 17β E2 was 10-8 mol/L, it had the strongest effect on the cell proliferation. When the concentration increased to 10-4 mol/L, the proliferation of chondrocytes was inhibited. With the increasement of 17β E2 concentration, the levels of CNP in the culture medium and the mRNA levels of CNP in the chondrocytes were significantly different. The highest levels of CNP protein and mRNA both appeared in 10-8 mol/L group, while the lowest levels both appeared in 10-4 mol/L group. IGF1 and its mRNA also reached the highest levels in 10-8 mol/L group,but the lowest concentration and mRNA level were in 10-10 mol/L group and 10-12 mol/L, respectively. Both CNP mRNA and protein levels were positive correlated with the proliferation of chondrocytes (P=0.000). Nevertheless, there was no significant correlation between the proliferation of chondrocytes and IGF1 mRNA or protein levels (P>0.05). Conclusion · 17β E2 modulates proliferation of rat growth plate chondrocytes in a dose-effect manner. It enhances proliferation at relatively low concentrations (10-10-10-8 mol/L) and inhibits proliferation at high concentration. This effect is positively related to CNP expression in chondrocytes.
