Objective To observe the effect of treating acute left heart failure with Shenmai injection and auxiliary conventional western medicine. Methods 132 patients were randomly divided into a control group and a treatment group, with 66 cases in each group. The control group was treated with lanatoside C, captopril, diuretics, and aminophylline. While the treatment group was additionally treated with Shenmai injection on the basis of the control group. Left ventricular ejection fraction(LVEF), left smothering end-diastolic diameter(LVEDD)value, the index of b-type natriuretic peptide(BNP), and 24 h dynamic electrocardiogram(ecg)were observed in both groups after 1 month’s treatment. Results LVEF and BNP were improved in both groups after the treatment[LVEF and BNP were(40.42 ± 4.32)%, (306.57 ± 201.21)pg/ml in the treatment group and(37.92±3.32)%, (451.51±294.23)pg/ml in the control group before the treatment;(35.28±4.15)%, (540.17±382.23)pg/ml in the treatment group and(35.13±2.35)%, (572.35± 422.21)pg/ml in the control group after the treatment], and the curative effect in the treatment group was better than the control group(P<0.05). LVEDD and 24 h average heart rate were also improved in both groups after the treatment [LVEDD and 24 h average heart rate were(59.81±59.81)mm, (79.62±6.38)times/min in the treatment group and(60.91±7.31)mm, (82.61±6.32)times/min in the control group before the treatment;(60.87 ± 7.75)mm, (85.03 ± 7.75)times/min in the treatment group and(61.81 ± 7.35)mm,(86.23 ± 8.35)times/min in the control group after the treatment], but there was no statistical differenc(P>0.05). Conclusion Shenmai injection has good effects in the treatment of acute left heart failure.

Objective To explore the effect of down-regulated methionine synthase reductase (MTRR) gene on the apoptosis and autophagy pathway, and offer a possible approach for the MTRR to reverse the multi-resistant ovarian cancer. Methods (1) The experiment was divided into 3 groups, SKOV3/DDP-MTRRi (down-regulated MTRR group), SKOV3/DDP-NC (negative control group), and SKOV3/DDP (blank control group). Different concentration of cisplatin (0, 1, 2, and 4 μg/ml) treated on 3 groups cells. The apoptosis rate was measured by flow cytometry (FCM). Autophagy was detected by immunofluorescence. Autophagy microtubule associated protein light chain 3β(LC3B) and p62 were detected by western blot. The formation of autophagosome of cells was observed by transmission electron microscope. (2) Detection of autophagy and apoptosis of SKOV3/DDP-MTRRi induced by rapamycin. The experiment was divided into 4 groups included rapamycin group (5 nmol/L rapamycin), rapamycin+cisplatin group (5 nmol/L rapamycin+4μg/ml cisplatin), cisplatin group (4μg/ml cisplatin) and blank control group. LC3B and p62 protein were detected by western blot. The survival rate cells were detected by methyl thiazolyl tetrazolium (MTT) method. The apoptosis rate was measured by FCM. (3) The 3 groups cells (SKOV3/DDP, SKOV3/DDP-NC and SKOV3/DDP-MTRRi) induced by a certain concentration of cisplatin (4 μg/ml) after 48 hours, then detecting the protein expression of caspase, Bcl-2 family in apoptosis pathway and the key proteins in phosphatidylinositol-3 kinase (PI3K)/protein kinase B (Akt) autophagy pathways by western blot, getting the time when the proteins′expression changed. Results (1) The 3 groups cells (SKOV3/DDP, SKOV3/DDP-NC, and SKOV3/DDP-MTRRi) induced by a certain concentration of cisplatin (4 μg/ml) after 48 hours, apoptosis and autophagy of 3 groups of cells were gradually increased with the increased concentration of cisplatin. The apoptosis rate of SKOV3/DDP-MTRRi cells [(26.2 ± 1.4)%] were significantly increased compared with the SKOV3/DDP-NC cells or SKOV3/DDP cells [(14.8 ± 2.4)%, (14.2 ± 2.4)%;all P<0.05] at 2μg/ml cisplatin. Immunofluorescence tests revealed that the aggregates of LC3B in SKOV3/DDP-MTRRi cells were more than that of SKOV3/DDP-NC cells and SKOV3/DDP cells. The expression of LC3B of SKOV3/DDP-MTRRi cells was lower than those of SKOV3/DDP-NC cells and SKOV3/DDP cells (P<0.05). The expression of p62 of SKOV3/DDP-MTRRi cells was higher than those of SKOV3/DDP-NC cells and SKOV3/DDP cells (P<0.05). The structure of chloroplast was integrity and autophagosome was dispersing in plastids of SKOV3/DDP-NC cells and SKOV3/DDP cells. Organelles disappear and vacuoles increased obviously in SKOV3/DDP-MTRRi cells, no autophagosome was observed. (2) The expression of LC3B of rapamycin+cisplatin group was higher than those of other 3 group cells (1.72±0.08,1.43±0.04, 1.37±0.11, and 1.11 ± 0.09;P<0.05). The expression of p62 of rapamycin + cisplatin group was significant decreased (0.58 ± 0.10,0.94 ± 0.12, 1.21 ± 0.11, and 1.57 ± 0.10; P<0.05). The survival rate of rapamycin + cisplatin group was higher than that of cisplatin group [(0.78±0.03)%vs (0.62±0.03)%;P=0.018], the apoptosis rate was significant decreased in rapamycin+cisplatin group [(59.0 ± 3.9)% vs (40.4 ± 3.0)%, P=0.019]. (3) The 3 groups cells (SKOV3/DDP, SKOV3/DDP-NC, and SKOV3/DDP-MTRRi) induced by a certain concentration of cisplatin (4μg/ml) after 48 hours, the expression of Bax in 3 groups cell were not evidently changed (P=0.661). The expression of Bcl-2 was significantly decreased in SKOV3/DDP-MTRRi cells (P=0.030). The expression of caspase-3, caspase-7, caspase-9, and poly (ADP-ribose) polymerase (PARP) were not evidently changed (P>0.05), but cleaved caspase-3, cleaved caspase-7, cleaved caspase-9, and cleaved PARP were significantly increased in SKOV3/DDP-MTRRi cells (P<0.05). For the autophagy pathway, the expression of phosphorylated Akt (p-Akt) and phosphorylated mammalian target of rapamycin (p-mTOR) were significantly increased (P<0.05), but Akt and mTOR had no significant variation. The expression of phosphatase and tensin homologue deleted on chromosome ten (PTEN) was significantly decreased (P<0.05). Conclusions MTRR silencing significantly increase cisplatin-induced apoptosis and reduce the autophagy induced by cisplatin in SKOV3/DDP cells. Down-regulation of MTRR enhanced the chemosensitivity of cisplatin-resistant ovarian cancer cells may be by activating caspase and Bcl-2 apoptosis family and inhibiting the PI3K/Akt autophagy pathway.

Objective To assess prevalence and risk factors of illness within the past 2 weeks among rural residents in Menglian,under the background of essential public health service implemented generally. Methods In February 2012, the questionnaire method was employed to investigate the two-week morbidity in 2011 rural residents sampled by multistage stratified random sampling from Menglian population. Results The prevalence, that of illness within two-week among 2011 rural residents in Menglian, was 97.5‰ (95%CI 84.5‰-110.5‰) . It was lower than that of the rural region IV in China (149.6‰, <0.05) .Its age trend was the same as that of the rural region IV in China,the prevalence in 0-14 years old children,however,was higher than the counterpart in the rural region IV in China. The diseases, which two-week morbidity ranked the top five, were acute upper respiratory infection, acute gastroenteritis, hyperostosis, acute tracheobronchitis and rheumatoid arthritis. The results of multilevel logistic regression model fitted by group-level explanatory variable mountainous area, individual-level random slopes variable gender and other individual background variables indicated that there were across-level interactions between mountainous area and gender ( <0.05), the family income lower than RMB 15000 (odds ration 3.2378, 95%CI 1.9014-5.5130) and age (odds ration 1.0163, 95%CI 1.0002-1.0327) had a positive effect to two-week morbidity, and contrasting to unmarried, married had a negative effect to two-week morbidity (odds ratio 0.4727, 95%CI 0.2534-0.8819) . Conclusions Comparing with that of the rural region IV in China before implementing essential public health service, the two-week morbidity in Menglian was lower. For further elevating the health level of population, the strategies, such as intensifying material and child hygiene in the mountain area, improving sanitary conditions of low income family, and updating health consciousness in single population,would be implemented.

Objective To assess the implementation of essential public health services (EPHS), and determine the main influencing factors for EPHS in Menglian. Methods In September 2012, the questionnaire survey method was employed to collect the data of EPHS implementation in 2011 in three community medical institutes and the EPHS evaluation of health staff sampled by stratified random sampling in Menglian. Results In 2011, the report rates of infectious diseases epidemics, public health emergencies and health inspection were all 100%, the inoculation rates of most vaccines were over 90%,and the health management rates of the children aged 0 to 6 years,pregnant and lying-in woman,aged population,hypertensives, type 2 diabetes patients and serious psychotics were high (about 85%) . The establishment rate of heath archives (60%to 70%),the controlling rates of blood pressure in the hypertensive population (about 50%), the rates of glycemic control in type 2 diabetes patients (55%to 70%) and the steady rates of serious psychotics (50% to 60%), however, were low. The implementation of EPHS was unbalance among towns, suburbs and outer suburbs. The main factors that influenced the EPHS implementation were inadequate human resources, insufficient or unused health devices, ambiguous responsibilities among the health institutes, non-cooperative behaviors, and unhealthy living habits in rural residents. Conclusions The implementation of many EPHS items is good. For promoting EPHS,it is necessary to train human resources,activiate unused health devices,get support of residents and carry out health education.
