Objective To test synchronization of cardiac mechanical contraction by means of advanced echocardiography and investigate the correlation of left ventricular ejection fraction (LVEF) and the indexes of mechanical dyssynchrony, and the relationship between DTI, STI and RT-3DE.Methods Control group (20 cases), chronic heart failure with a widened QRS complex (12 cases) and chronic heart failure with a shortened QRS duration (10 cases) were selected. We evaluated mechanical dyssynchrony with the DTI, the STI and the RT-3DE, and analyzed the correlation between the improvement degree of cardiac function and indexes of mechanical dyssynchrony, and the correlation between DTI, STI and RT-3DE. Results (1) In CHF groups (including shortened QRS group and widened QRS group), the indexes of synchronization of cardiac mechanical contraction were higher than control group ( <0.05) . (2) However, the indexes of mechanical dyssynchrony before operation showed no statistically significant difference between the widened QRS group and the shortened QRS group (>0.05) . (3) In CHF groups (including shortened QRS group and widened QRS group), the indexes of mechanical dyssynchrony before operation were higher more than after operation ( <0.05) . (4) In postoperation, the indexes of mechanical dyssynchrony showed no statistically significant difference between the widened QRS group and the shortened QRS group ( >0.05) . (5) There was a significant negative correlation between the LVEF and the indexes of mechanical dyssynchrony (<0.01) . (6) .In the indexes of synchronization of cardiac mechanical contractions, there are significant positive correlations between the DTI, the STI and the RT-3DE ( <0.01) . Conclusion Echocardiography can be used to screen CHF patients,and patients with left ventricular synchronous (including shortened QRS duration) can also be benefited from CRT.

Objective To study the ralationship of arrhythmias and heart electrical parameters changes after transcatheter closure of ventricular septal defect (VSD) .Method 50 patients had been successfully finnished the transcatheter closure of ventricular septal defect,and then we observed ralationship of arrhythmias and heart electrical parameters changes. Results (1) Compared with the situation of VSD occluder preoperative and postoperative, during follow-up there were 20 arrhythmia cases, including bundle branch block 16 cases, including the complete left bundle branch block 2 cases,complete right bundle branch block 4 cases,a transient third-degree trioventricular conduction block 1 case, most return to normal in the follow-up. 2 Intracavitary electrogram showed before and after transcatheter closure:A-V conduction parameters A-H,H-V value of (75.10 ± 14.34) ms vs (80.67±23.03) ms and (47.9±12.61) ms vs (50.07±15.23) ms,the difference was not statistically significant ( >0.05) . Conclusions (1) Some patients with new ECG changes after transcatheter closure of VSD, manifested as an increase in bundle branch block in a week, but most return to normal,the prognosis is good. (2) Intraoperative A-H,H-V extension is not related with with postoperative slow arrhythmia;(3) Arrhythmia is a common complication after VSD transcatheler closure, to strictly selecte indications,and to avoid too large diameter are the effective measures to reduce the arrhythmias after transcatheter closure of ventricular septal defect (VSD) .

BACKGROUNDLung cancer is a serious health problem in public. Its morbidity and mortality have been increasing rapidly. The mortality of lung cancer in women also increases year by year, in which most of the cases are non-smoking women, and the risk factors still are unclear. The aim of this study is to explore the effects of air pollution in room, passive smoking and other factors on risk of lung cancer.

METHODSA total of 618 newly diagnosed female patients with primary lung cancer were enrolled. The controls were selected randomly in the general population in urban districts. Two trained interviewers performed this interview face-to-face using the same questionnaire. The content of questionnaire included the characteristics of demography, history of passive smoking, exposed history of cooking fume, fuel exposure, exposed history of coal fume, history of using 'Kang', pulmonary disease history, cancer history of relatives and occupational history.

RESULTSPassive smoking in childhood was related with lung cancer of non-smoking women (OR= 1.81 , 95%CI=1.46-2.24). The exposure to the cooking fume was of great significance (OR=3.18, 95%CI= 2.55 -3.97). The relationship between coal fume and lung cancer was significant (OR=2.56, 95%CI= 1.83 -4.55). The pulmonary disease history including tuberculosis, chronic bronchitis, asthma, pneumonia, emphysema was strongly associated with lung cancer (OR=1.80, 95%CI=1.43-2.27). The family history of cancer significantly increased the risk of lung cancer (OR=2.09, 95%CI=1.46-3.00), especially the lung cancer history in the first relatives (OR=2.46, 95%CI=1.55-3.90). After adjusting other factors, logistic analysis showed that cooking fume (OR=4.11, 95%CI=2.14-7.89), the pulmonary disease history (OR= 2.05 , 95%CI=1.08-3.93), and the family history of lung cancer (OR=2.89, 95%CI=1.30-6.41) were significant factors.

CONCLUSIONSThe results show that passive smoking in childhood, cooking oil exposure, coal fume exposure, pulmonary disease history including tuberculosis and family history of lung cancer are risk factors of lung cancer in non-smoking women.

Long-term spaceflight affects numerous organ systems in the body, including metabolic dysfunction. Recently, ample evidence has demonstrated that the liver is a vulnerable organ during spaceflight. However, the changes in hepatocyte proliferation and cell cycle control under microgravity remain largely unexplored. In the present study, we first confirmed that the serum levels of aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase, biochemical markers of liver function, were altered in rats under tail suspension (TS) conditions to simulate microgravity, as shown in previous reports. Next, we demonstrated that the cell proliferation activity, determined by Ki67, PCNA and PH3, was significantly decreased at the different TS time points (TS for 14, 28 and 42 days) compared with that in the control group. Consistently, the positive cell cycle regulators Ccna2, Ccnd1, Cdk1, Cdk2 and cyclin D3 were also significantly decreased in the TS groups as shown by quantitative real-time PCR and western blotting analysis. Subsequent analysis revealed that the aberrant hepatocyte proliferation inhibition under simulated microgravity was associated with the upregulation of miR-223 in the liver. We further found that miR-223 inhibited the proliferation of Hepa1-6 cells and identified CDK2 and CUL1 as its direct targets. In addition, the decreased expression of CDK2 and CUL1 was negatively correlated with the level of p27 in vitro and in vivo, which may have been responsible for retarding hepatocyte proliferation. Collectively, these data indicate that upregulation of miR-223 was associated with the inhibition of liver cell growth and reveal the role of miR-223 in rat hepatocyte proliferation disorders and the pathophysiological process under simulated microgravity.

OBJECTIVE: To evaluate the efficacy of non-invasive prenatal screening (NIPS) for fetal sex chromosome anomalies. METHODS: A retrospective analysis was carried out for 20 802 women undergoing NIPS screening. For 165 cases suspected for fetal sex chromosomal anomalies, the results of invasive prenatal diagnosis were obtained. RESULTS: Among the 165 cases suspected for fetal sex chromosome anomalies, 129 have accepted invasive prenatal diagnosis, and 45 were confirmed, which yielded a positive predictive value of 34.88%. These included 16 cases of 47,XYY, 10 cases of 47,XXY, 6 cases of 45,X/46,XX, 5 cases of 47,XXX, 3 cases of 45,X, 1 case of 45,X/46,X,i(X)(q10), 1 case of 45,X/46,X,del(X)(q22), 1 case of 46,X,del(X)(q22), 1 case of 46,X,del(X)(p11) and 1 case of Xp22.31 1.2 Mb deletion. CONCLUSION NIPS has limited value for detecting fetal sex chromosome anomalies. Karyotyping analysis combined with other diagnostic techniques can offer effective prenatal diagnosis for suspected cases.
