Objective To master the epidemic situation and control effect of schistosomiasis in Yugan County,Jiangxi Prov-ince. Methods The data of the schistosomiasis prevalence in human and cattle as well as Oncomelania hupensis snail status were collected and the change trends were analyzed in Yugan County from 2008 to 2012. Results The schistosome infection rates of residents in Yugan County have declined every year since 2008,and currently,the prevalence of schistosomiasis was at a low lev-el. No acute schistosomiasis case was found during the past 5 years. In 2012,the infection rate of bovine was above 1%in 88 en-demic villages,and the area with schistosome infected snails was 10 hm2. Conclusion In order to achieve the goal of schistosomi-asis transmission control in the whole county in 2015,the comprehensive control measures based on infection source control should be strengthened.

Objectives To explore the correlation between the population characteristics of sero-reactivity with quantitative antibody based-IHA and the transmission parameters,such as epidemic situation,transmission status or infection trend in population.Methods The residents in one endemic administrative village were simultaneously examined by Kato-Katz technique for parasitological stool examination,as well as by immuno-diagnostic technique IHA for detection of IgG antibody against soluble egg antigen for two consecutive years.The results of examination were analyzed and compared on the diagnostic parameters of IHA,the correlation of the changes of positive rates and antibody levels of IHA with the changes of infection trend in population and the distribution of antibody levels between 'the true negative' and 'the true positive'.Results When Kato-Katz technique based on 2 stool samples,each read in 3 thick smears,was used as the reference,the overall sensitivity of IHA was high (from 77.27% to 85.48%) with a relatively poor specificity of lower than 60%,the negative predict value (NPV) was excellent of higher than 94%.The specificity of IHA decreased with the increase of the age in different age-groups of population,showing the highest among the younger less than 15 years old.The distribution trends of positive rates of antibody in different age groups by IHA showed similar to that of egg positive rate detected by Kato-Katz although the positive rates of IHA were higher than these by Kato-Katz,which showed that a higher false positive (from 41.90% to 44.56%) and a certain false negative (from 14.52% to 22.73%)existed in IHA.The positive rate of antibody decreased slowly among the individuals with S.japonicum infection,who received treatment.There was an overlap in the distribution of antibody levels between ' the true negative' and ' the true positive'.Conclusions Under the current schistosomiasis epidemic situation in China,IHA is valuable in the epidemiologic surveys.It should be of further deliberation applying IHA as the screening approaches for identification of target individuals for treatment or determination of the infection rate in community and IHA needs to be combined with the parasitological examination.

Objective To evaluate the effects of drug-eluting stents (DES) versus bare-metal stents (BMS) on clinical outcomes in patients with acute ST-segment elevation myocardial infarction (ASTEMI) receiving primary percutaneous coronary intervention (PPCI). Methods The 217patients with ASTEMI receiving PPCI from Jan. 2005 to Dec. 2007 were enrolled in this study. And they were divided into two groups: DES group (n=92) and BMS group (n=125). The baseline characteristics including age, gender, angiographic characteristics, stents characteristics, Killip classification, cardiac troponin I(CTnI)levels, left ventricular ejection fraction(LVEF), hemoglobin levels, hypertension, diabetes, hyperlipidemia, obesity and smoking of the two groups were collected.Clinical follow-up end point were major adverse cardiac event(MACE)including death, acute myocardial infarction, stent thrombosis and stent restenosis. Clinical follow-up duration was(16.8±11.3) months (6-38 months). Results The average age (years), rate of Killip classification (class 2, 3, 4), average diameter (mm) of stent were significantly higher in BMS group than in DES group(64.6±11.9 vs. 61.2±11.8, t=2.09, P=0.037;25.9% vs. 12.2%, χ2=5.53, P=0.019;3.07±0.38 vs. 2.91±0. 40, t=2.78, P=0.006). And the average LVEF (%) was significantly lower in BMS group than in DES group (55.4±11.9 vs. 60.3±12.8, t= -2.57, P=0.011). The average length (mm) of stent, rate of stent post dilatation and diabetes were significantly higher in DES group than inBMSgroup (32.8±16.2 vs. 26.2±11.2, t=-3.54, P=0.001;45.7% vs. 21.6%, χ2=13.85, P=0. 000;28.2% vs. 16.0%, χ2=4.77, P=0.030). MACE occurred in 36 patients during clinical follow-up, 6 in DES group and 30 in BMS group. Incidence of MACE was significantly lower in DES group than in BMS group(6.5% vs. 24.0%, χ2=11.70, P＜0.01). Conclusions Using DES in ASTEMI patients is safe and may improve clinical outcomes by reducing incidence of MACE compared with BMS.

Objectives We sought to determine the factors that predicted in-hospital heart failure(HF)in patients undergoing successful primary percutaneous coronary intervention(PCI)for ST-segment elevation myocardial infarction(STEMI). Methods The clinical and angiographic data were retrospectively reviewed in patients undergoing successful primary PCI for their ifrst STEMI. According to the occurrence of in-hospital HF, patients were divided into HF group and non-HF group. The incidence and predictors of in-hospital HF and its impact on prognosis were determined. Results A total of 834 patients were included, among them 94 patients (11.3%) were in the HF group and 740 patients(88.7%) were in the non-HF group. The mean age was (62.9±12.9) years and 662 patients (79.4%) were male. All-cause mortality at 30 days was signiifcantly higher in the HF group than in the non-HF group (24.5%vs. 1.5%, P<0.001). In Cox regression analysis, left anterior descending artery (LAD) as the culprit vessel (HR 2.173, 95% CI 1.12~4.212, P=0.022), ln 24 h NT-proBNP (HR 1.904, 95%CI 1.479~2.452, P<0.001), 24 h hsCRP≥11.0 mg/L (median) (HR 2.901, 95%CI 1.309~6.430, P=0.009) and baseline serum glucose (HR 1.022, 95%CI 1.000 ~ 1.044, P=0.046) were independent predictors of in-hospital HF. Receiver operator characteristic analysis identiifed 24 h NT-proBNP ≥ 1171 pg/ml (c=0.883, P < 0.001) and 24 h hsCRP ≥ 13.5 mg/L (c=0.829, P < 0.001) were the best cut-off values in discriminating in-hospital HF with a sensitivity and speciifcity of 92.5%and 76.8%for 24 h NT-proBNP, 86.0%and 77.0%for 24 h hsCRP, respectively. Even among patients with LAD as the culprit vessel, the incidence of in-hospital HF was only 0.4%in patients whose 24 h NT-proBNP was<1171 pg/ml and 24 h hsCRP was<13.5 mg/L;while the incidence of in-hospital HF was up to 60.9%in patients whose 24 h NT-proBNP≥1171 pg/ml and 24 h hsCRP≥13.5 mg/L (P<0.001). Conclusions The incidence of in-hospital HF was still high in STEMI patients even after successful primary PCI. Patients with in-hospital HF had poor prognosis. LAD as the culprit vessel, hsCRP, NT-proBNP and baseline serum glucose were independent predictors of in-hospital HF. Assessment and combined use of different serum biomarkers were effective methods to estimate the risk of in-hospital HF in STEMI patients undergoing primary PCI.

Objective:To compare the effectiveness of proximal femoral nail antirotation (PFNA) with intertrochanteric antegrade nail (InterTAN) in the treatment of intertrochanteric fractures in the elderly. Methods:A retrospective study of 62 elderly patients with intertrochanteric fractures who received two operation methods from Sep 2014 to May 2016 was done. There were 28 patients in PFNA group, and 34 patients in InterTAN group. The operation time, blood loss in operation, hospitalization time, healing time, and Harris hip joint functional score were compared and analyzed. Results:Operation time and the amount of intraoperative blood loss in PFNA group were less than that in InterTAN group. Hospitalization time,fracture healing time and Harris hip joint functional score after ten months had no significant difference between the two groups. And 59 cases in total were followed up with an average of 11.5 months (from 9 to 16 months) . In PFNA group, 27 patients were followed up, and one patient was lost to follow up, who died because of chronic renal insufficiency. The rest 26 patients all achieved bony union (including one case of hip versus) . At follow-up 9 months, hip joint function was excellent in 18 cases, good in 6, fair in 2, bad in 1, and the excellent-good rate was 88.9%. In InterTAN group,32 patients were followed up,and two cases were lost to follow up. In followed-up cases, there was one patient who was no healing of fracture. After hip arthroplasty, this patient got recovery. The hip joint function was excellent in 21 cases, good in 7, fair in 3, and bad in 1. The differences between the two groups were not statisticaly significant. Conclusion:Both PFNA and InterTAN can treat intertrochanteric fractures in the elderly with good result,but PFNA has obvious advantages over InterTAN on less hemorrhage and operation time.

Recent studies have shown that acute blood glucose elevation in patients with ST-segment elevation myocardial infarction (STEMI) suggests a poor prognosis. To investigate the effect of fasting blood glucose (FBG) on the risk of heart failure (HF) and left ventricular systolic dysfunction (LVSD) in non-diabetic patients undergoing primary percutaneous coronary intervention (PCI) for acute STEMI, we retrospectively recruited consecutive non-diabetic patients who underwent primary PCI for STEMI in our hospital from February 2003 to March 2015. The patients were divided into two groups according to the FBG level. A total of 623 patients were recruited with an age of 61.3 ± 12.9 years, of whom 514 (82.5%) were male. The HF risk (odds ratio 3.401, 95% confidence interval (CI) 2.144-5.395, P < 0.001) was significantly increased in patients with elevated FBG than those with normal FBG. Elevated FBG was also independently related to LVSD (β 1.513, 95%CI 1.282-1.785, P < 0.001) in a multiple logistics regression analysis. In conclusion, elevated FBG was independently associated with 30-day HF and LVSD risk in non-diabetic patients undergoing primary PCI for STEMI.
