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.

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.

Background: Integrative traditional Chinese and western medicine may be a new approach to improve the eradication rate of Helicobacter pylori (Hp).Aims: To compare the efficacy and safety of Weifuchun tablet versus bismuth combined with standard triple regimen as the first-line therapy of Hp infection.Methods: A total of 141 patients with Hp infection and na(i)ve to treatment were randomly assigned into 3 groups receiving a 14-day eradication therapy.In standard triple therapy group, esomeprazole, amoxicillin and clarithromycin were given twice a day;while in Weifuchun group and bismuth group, Weifuchun tablet and bismuth potassium citrate were added, respectively, to the standard triple therapy.Hp eradication was assessed by 13C-urea breath test at least 6 weeks after the end of treatment.Hp isolates were tested for resistance to antibiotics.Results: One hundred and twenty-eight patients completed the study.Hp eradication rates in Weifuchun group, bismuth group and standard triple therapy group were 83.7%, 91.8% and 79.1%, respectively by ITT analysis and 88.4%, 97.8% and 84.6%, respectively by PP analysis.The eradication rate of Weifuchun group was lower than that of bismuth group and higher than that of standard triple therapy group, but the differences were not statistically significant (P>0.05).Only PP eradication rate of bismuth group was significantly higher than that of standard triple therapy group (P<0.05).The resistant rates of Hp to clarithromycin, amoxicillin and metronidazole were 33.3%, 2.9% and 70.5%, respectively.For eradication of clarithromycin resistant strains, bismuth group was superior to Weifuchun group and standard triple therapy group (100% vs.60.0% and 66.7%, P all <0.05).All three eradication regimens showed good compliance, and no significant difference in incidence of adverse events was found between the three regimens (P>0.05).Conclusions: Weifuchun tablet combined with standard triple regimen is safe and effective for use as first-line treatment for Hp infection, however, the eradication rate is relatively low in cases infected with clarithromycin resistant strains.Bismuth combined with standard triple regimen is a good alternative in areas with high clarithromycin resistance and regions where tetracycline is unavailable.

ObjectiveTo evaluate the efficacy and safety of electrical acupuncture therapy through adhesive surface electrodes and concomitant auricular acupuncture therapy on acute spinal cord injury.MethodsA total of 56 acute spinal cord injury patients with American Spinal Injury Association(ASIA) impairment grading of A and B were recruited into this study.They were randomly divided into the acupuncture and control groups.In the acupuncture group,electrical acupuncture therapy via the adhesive surface electrodes and auricular acupuncture were applied.Rehabilitation therapy was also provided to the patients during acupuncture therapy.In the control group,only rehabilitation therapy was provided to the patients.The ASIA neurologic and functional scores and the Functional Independence Measure(FIM) scores were assessed during the time of admission,hospital discharge,and 1-year postinjury follow-up.There were no adverse events.ResultsThere were significant improvements in neurologic(sensory and motor),functional,and FIM scores in the acupuncture group compared with the control either when hospital discharged or 1-year postinjury follow-up.There was no adverse events.ConclusionThe early use of concomitant auricular and electrical acupuncture therapies are effective and safe in treating acute spinal cord injury.

Background Glycogen synthase kinase-3β (GSK-3β)plays an important role in glucose metabolism,and it may be affect the occurrence of diabetic retinopathy(DR).ObjectiveThe present study was to investigate the effect of valsartan and fluvastatin on the expression of GSK-3β in retina of diabetes rat model.MethodsDiabetes mellitus models were induced by intrapenetoneal injection of streptozotocin(STZ) in 47 clean Sprague-Dawley(SD) rats and were then randomedly divided into 4 groups.Ten other normal rats were served as normal control group.Sodium carboxy methyl cellulose solution,valsartan,fluvastatin,valsartan+fluvastatin and sodium carboxy methyl cellulose solution was given by oral once per day for 12 weeks respectively in diabetes control group ( n =12),valsartan group ( n =12 ),fluvastatin group ( n =11 ),valsartau + fluvastatin group ( n =12 ) and normal control group.Twelve weeks after administration of drugs,blood glucose was measured and compared among various groups,and the expression of p-GSK-3β ( Ser-9 ) protein in retina was quantified and located by Western blot and immunohistochemistry,respectively.Results Twelve weeks after use of drugs,the level of blood glucose was(5.28±0.30),(26.08±3.33 ),(26.03 ±2.66 ),(25.90± 2.86 ),(25.99 ± 2.14 ) mmol/L in the normal control group,diabetes control group,valsartan,fluvastatin,valsartan + fluvastatin group,respectively,showing a significant difference among the 5 groups ( F =110.74,P＜0.01 ).Western blot showed that the grey value of p-GSK-3β ( Ser-9 ) /β-actin in retina in the diabetic control group was significant higher than the normal group(2.774±0.139 vs 1.927±0.111,q =15.79,P＜0.01 ),and that in valsartan,fluvastatin,valsartan+fluvastatin group was lower than the diabetic control group ( 1.895 ±0.090,2.051 ± 0.113,1.537 ± 0.071 vs 2.774 ± 0.139 ) ( q =1 3.69,13.48,23.06,P ＜ 0.01 ).The grey value of p-GSK-3β (Ser-9)/β-actin in the valsartan+fluvastatin group was declined in comparison with the valsartan group and fluvastatin group ( q =6.67,9.58,P＜0.01 ).Immunohistochemistry showed that the p-GSK-3β(Ser-9) protein was expressed all over the retinal layers and obviously in retinal ganglion cell layer(GCL) in normal control group.But the p-GSK-3β(Ser-9) protein was expressed significantly in diabetic control group.The expression of p-GSK-3β (Ser-9)protein was attenuated both in valsartan and fluvastatin groups and further attenuated in valsartan + fluvastatin group. Conclusions p-GSK-3β (Ser-9) protein is overexpressed in GCL of retina of diabetes rat.Both valsartan and fluvastatin can inhibit the expression of p-GSK-3β (Ser-9) and even getting stronger when they combined.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.
