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 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 study the induction of IL-6 on expression and activity of tissue factor (TF)in peripheral blood monocytes(PBMCs).Methods rhIL-6 100 ng/L and rhIL-6 100 ng/L+ rhIL-6 MoAb 10?g/L were used respectively to stimulate the PBMCs for 24 h,PBMCs without any stimulation as control group,to study the changes of antigen content,mRNA expression and the ac- tivity of the TF.Results The antigen content,mRNA expression and activity of TF were increased significantly in 100 ng/L rhIL-6 group as compared with rhIL-6 100 ng/L+rhIL-6 MoAb 10?g/L and control groups(P＜0.01).Conclusions rhIL-6 can induce the increase of antigen expression,activity and mRNA expression in PBMCs,and these effects can be suppressed successfully by rhIL-6 MoAb. This study demonstrated that there was potential relations between cytokines and thrombogenesis, which may play an important role the pathogenesis of chronic rejection.

Objective:To measure CT linearity and evaluate if it would show linear relationship between coefficient and attenuation.Methods:The Catphan phantom was used to measure CT linearity in 18 computed tomography equipments,and the results were calculated.Results:(1)The CT linearity were qualified in 14 equipment but 4.Conclusion:(1)There are many factors which affect CT linearity.The artifact will be produced if the CT linearity is unqualified.(2)CT linearity must be calibrated periodically to assure the stability of the CT linearity and to make for the accurate diagnoses.

Objective:To explore the relationship among occupational benefits,turnover intention and quality of life in nurses using structural equation model,thus to provide evidence for improving the quality of life.Method:We conduct a survey among 965 nurses using the general information questionnaire,the occupational benefits scale,turnover intention scale (TIS) and the SF-36 scale.Restult:The total score of occupational benefits was (135.79 ± 18.82),the TIS score was (13.48 ±4.11),and the SF-36 score was (532.91 ± 141.75).There was a positive correlation between occupational benefits and the quality of life,and the turnover intention was negatively correlated with the quality of life.Structural equation model analysis showed that the occupational benefits and turnover intention had a direct significant effect on nurses' quality of life;occupational benefits has a direct negative effect on turnover intention,and indirectly effects quality of life of nurse through the mediating effect of turnover intention.Conclusion:The nurses' quality of life needs to be improved,and occupational benefits and turnover intention have significant prediction effect on quality of life.

AIM: To evaluate the relationship between axial length ( AL ) , corneal and lens refractive power, and the refractive error in children.
METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry ( ZEISS IOL-Master) , and corneal K and anterior chamber depth ( ACD) were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia (SE<0), hyperopia (SE>+0. 50D) and emmetropia ( 0 to + 0. 50D ). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters.
RESULTS:Totally 44 subjects, 88 eyes, average 9. 04±2.39 years, spherical equivalent (SE) -3. 50D to +8. 75D. Hyperopic AL was shorter than the other two groups ( P<0.05), same trend in lens power. No significant differences among the 3 groups in corneal K and ACD. There was a negative correlation between age and SE, SE and AL, SE and lens refractive power, and there was a positive correlation between age and AL, age and lens power.
CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger.

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.
