Objective To investigate the effects of rocuronium on the neuromuscular junction of rat diaphragm. Methods One hundred and sixty rats were used in the study which was approved by the Animal Care Committee of the General Hospital of PLA. In isolated non-uniformly stretched muscle preparation (INSMP) of rat diaphragm, micro-endplate potentials (MEPP) and endplate potentials (EPP) were recorded simultaneously with one microelectrode of one endplate. The effects of rocuronium in dosages of 2.5, 5, 10, 20?g/ml on the amplitude and frequency of MEPP and the amplitude of EPP were observed. Results Rocuronium could decrease both the amplitude and frequency of MEPP obviously and the onset time was 1min after drug administration. The amplitude of EPP was depressed by rocuronium in a dose of 5?g/ml at 3min. Neither 2.5?g/ml nor 0.5?g/ml of rocuronium produced any effect on the amplitude of EPP. Conclusion The results indicated that rocuronium might produce a rapid and early presynaptic effect on neuromuscular junction in INSMP in rats.

Objective: To evaluate the efficacy and safety for the application of low-dose vitamin K antagonist (VKA) during whole pregnancy and low-molecular-weight heparin/heparin at early pregnancy in patients after mechanical heart valve replacement. Methods: We searched the Cochrane library (2016 Issue 2), PubMed, EMbase, CBM, Tsinghua Tongfang (CNKI), Wanfang and VIP databases to collect the literatures for the application of low-dose VKA during whole pregnancy and low-molecular-weight heparin/heparin at early pregnancy up to 2016-06. The literatures were independently screened by 2 reviewers and Meta-analysis was performed using RevMan 5.3 software. Results: 12 studies were finally enrolled. Meta-analysis presented that compared with the application of low-molecular-weight heparin/heparin at early pregnancy, low-dose VKA during whole pregnancy showed decreased valvular thrombosis rate (OR=0.26, 95% CI 0.13-0.54, P<0.001), lower spontaneous abortion rate (OR=1.99, 95% CI 1.21-3.26, P=0.006) and increased fetal abnormality rate (OR=3.39, 95% CI 1.11-10.37, P=0.03); while the maternal mortality (OR=0.79, 95% CI 0.24-2.58, P=0.70), peri-natal bleeding rate (OR=0.56, 95% CI 0.27-1.18, P=0.13) and the incidence of stillbirth (OR=1.80, 95% CI 0.94-3.44, P=0.07) were similar between two conditions. Conclusion: Current evidence indicated that the application of low-doseVKA during whole pregnancy decreased the rates of valvular thrombosis and spontaneous abortion in patients after mechanical heart valve replacement, while increased the rate of fetal abnormality. Further investigation is needed to confirm the above conclusion.

With the progress of society and development of sexual medicine, the therapeutic effects of female sexual dysfunction (FSD) have been improved increasingly. This review summarizes the basic therapeutic approaches to FSD, including psychotherapy, sexual behavior therapy, mechanical skills, life style adjustment, physical exercise, acupuncture, medication, surgery, and gene therapy. It also points out the objective understanding of the limitations of the available therapeutic methods, with stress on patient-oriented comprehensive therapeutic principles and increased attention to recognition education among the patients so as to improve the present status of FSD treatment.

Objective: To discuss the safety issues of moxibustion therapy in view of moxibustion materials. Methods: The analyses and assessment were performed based on the survey carried out on the use of moxa, modem and ancient records, modern studies, and clinical applications. Results:Moxa has been used as both a medicine and a food for a long history in China. Regarding moxibustion specifically, moxa has been proven to be the optimum choice for moxibustion therapy,through practices and experiments by doctors from different generations. No records have shown any side- or adverse-effects of moxa applied in moxibustion therapy. Conclusion: Moxa has been used in multiple ways for several thousands of years by Chinese people. As the main material for moxibustion therapy, its safety has been proven by documents and clinical practices.

Objective To investigate the effect of EZH2 knockdown on cell proliferation ,invasion ,migration and apoptosis in hu-man bladder cancer cell line by small interfering RNAs(siRNA) .Methods The siRNA-expressing plasmid targeting EZH2 gene was constructed and transfected into T24 cells .RT-PCR was used to detect the EZH2 gene′s expression at the level of mRNA ;pro-liferation ,invasion and migration of T24 cells were examed in vivo by MTT ,wound healing assay and Transwell chamber migration assay .Finally ,Annexin V-FITC/PI flow cytometric analysis was performed for cell apoptosis .Results The siRNA-expressing plas-mid targeting EZH2 gene successfully inhibited EZH2 gene’s expression in T24 cells .The expression of mRNA was significantly inhibited compared with negative control groups (P<0 .05) .After the transfection of the plasmid 48 hours ,the growth inhibition rate was 37 .9% ,which was higher than the negative control group(P<0 .05) .24 hours after wound healing ,the migration distance of transfected group cell was(1 .37 ± 0 .12) ,which was lower than the negative control group(P<0 .01) .Compared with the nega-tive control group ,invasion capability of EZH2-siRNA group was dropped by 67% (P<0 .01) .48 hours after transfection ,the early and secondary apoptosis rate of T 24 cells were 22 .80% and 3 .60% respectively ,which were higher than the negative contral group (P<0 .01) .Conclusion The siRNA interference EZH2 can significantly inhibit cell proliferation ,invasion and migration of T24 cells ,meanwhile promote its apoptosis .It provides a theoretical basis for further study of bladder cancer gene therapy .

The relationship between vascular endothelial growth factor-C (VEGF-C)/vascular endothelial growth factor receptor 3 (VEGFR-3) expression and clinicopathologic features of the patients with non-small cell lung cancer (NSCLC) was investigated. The expression of VEGF-C and VEGFR-3 was assessed in 65 patients with NSCLC by immunohistochemistry. The significance of VEGF-C and VEGFR-3 expression was analyzed statistically. The results showed that VEGF-C and VEGFR-3 were highly expressed in cytoplasm and membrane in lung cancer tissues with the positive rate being 55.4 % and 52.3 % respectively, while there was no expression in the normal lung tissues. The expression of VEGF-C was significantly increased in adenocacinoma as compared to other types of NSCLC (P<0.05). The VEGFR-3 expression was closely related with lymph node metastasis (P<0.01) and TNM stage (P<0.05). There was a positive correlation between the VEGF-C and VEGFR-3 expression in NSCLC patients (r=0.658, P<0.01). It is suggested that VEGFR-3 plays an important role in the lymphatic metastasis of NSCLC. The interaction between VEGF-C and VEGFR-3 may be deeply involved in the mechanism of lung cancer metastasis.
