Objective To investigate the hygienic quality of drinking water in rural areas of Xiamen and to provide scientific bases for the improvement of drinking water quality and protection of human health.Methods The well water samples were sampled randomly according to the proportion and the water quality was analysed and the incidences of water-borne diseases were investigated in Xiamen rural areas.Results Water sources for drinking water in most parts of Xiamen rural areas are shallow-layer ground-water.As being polluted by surface ranoff water,the indices of total bacte-rial count and coliform bacteria in the well water were heavily over the standard with the over standard rates61.6%and85.1%respectively.The contents of fluoride in drinking water were at the higher levels(the highest one was1.6mg /L)in some villages and still there were more villages where the iodine contents in drinking water was at the lower level.The iodine content in well water,spring water and tap water was11.1,2.5and4.45?g /L respectively,in which the unqualified rate was48.3%,90%and58.1%respectively.The incidence of dental fluorosis in school-age children was70%in the high fluoride areas and the incidence of endemic goiter was20.9%in the low iodine areas.Conclu-sion The main hygienic problem of drinking water in rural areas of Xiamen was biological pollution and lower iodine contents and higher fluoride contents in water in some areas.In order to eliminate the water-borne diseases,the most important rural sanitary measures need to be taken:improving the sanitary conditions around the wells,repairing the well wall s and using deep ground-water or drinking water and developing centralized water supply in the areas with unbal-anced health-related microelemeuts in drinking water if possible in some villages.

Objective To investigate the comparison of the clinical treatment efficacy of propafenone and amiodarone in patients with paroxysmal supraventricular tachycardia ( PSVT ) .Methods Retrospective a total of 89 patients with PSVT from June 2013 to June 2015 in our hospital were selected.According to the different administration methods, the patients were divided into the propafenone group of 46 cases and the amiodarone group of 43 cases.The changes of left ventricular end-systolic volume, left ventricular end-diastolic volume, ejection fraction, cardioversion success rate, mean cardioversion time, heart rate and side effects were compared.Results After treatment, the left ventricular end-systolic volume (52.31 ±8.34) mL/m2 , (54.28 ±7.23) mL/m2, left ventricular end-diastolic volume (47.31 ±8.56) mL/m2, (45.28 ±7.16) mL/m2 and ejection fraction (61.57 ± 0.76)%, (61.39 ±0.69)% were without significant differences.After treatment, the heart rates of the two groups were significantly decreased, the propafenone group ( 85.31 ±12.84 ) times/min, amiodarone group ( 87.26 ±11.95 ) times/min, and there were not significant differences.The recovery time of propafenone group was ( 19.34 ±4.76 ) , higher than the amiodarone group ( 25.69 ±6.09 ) ( P <0.05 ).But the success rate of cardioversion (52.17%) was lower than the amiodarone group (88.37%) (P<0.05).The side effect rates in the propafenone group (21.74%) was significantly higher than that in the amiodarone group ( 4.65%) ( P <0.05 ) .Conclusion Propafenone and amiodarone cardioversion PSVT have achieved good results, but propafenone rapid onset, the average cardioversion time is short, which is only suitable for acute tachycardia and without serious organic heart disease patients.Amiodarone onset is slower,but the cardioversion success rate is higher.

This study is to elucidate the immunoregulation mechanisms of artesunate (AST) on allergic contact dermatitis (ACD). Pharmacodynamics analyses, HE staining, semi-quantitative RT-PCR and Western blotting were used to explore the effects of AST on the related cytokines, transcription factor and signaling molecule of ACD respectively. The results indicated that topical administration of AST not only reduced the increase of ear swelling, spleen index and inflammatory cells infiltration in ACD mice, but also inhibited remarkably the expression of IFN-gamma, T-bet and NF-kappaB p65. It's suggested that AST could exhibit suppressive effects on inflammatory response and immune function of ACD, which indicates the possibility of developing AST as a novel immunoregulatory agent in the treatment of ACD and other immune-related diseases.

Objective To investigate the relationship between cardiovascular risk factors and arterial elasticity in elderly hypertensive patients.Methods 253 subjects were divided into two groups:hypertension group (n=141) and non-hypertension group (n =112).Carotid-femoral pulse wave velocity (C-FPWV),carotid-radial PWV (C-RPWV),height and weight were determined.Fasting plasma levels of blood glucose (BG),blood lipids,insulin,endothelins (ET),nitric oxide (NO) and high sensitivity C-reactive protein (hsCRP) were assessed.Results C-FPWV and CRPWV were higher in hypertension group than in non-hypertension group [(11.7±1.9) m/s vs.(9.7±1.1)m/s,(11.7±1.7) m/s vs.(9.4±1.1)m/s,t=8.43 and-6.30,both P＜0.01].Body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),levels of triglyceride (TG),BG,ET,NO and hsCRP,HOMA-IR had significant differences between the two groups (t=-5.27,-4.18,-6.00,6.29,-4.18,-4.86,-3.41,respectively,all P＜0.05).Pearson correlation analysis showed that CFPWV was correlated with SBP,age,DBP,fasting BG,NO,ET,TG,HOMA IR,cholesterol (CHO),hsCRP (r=0.534,0.374,0.340,0.338,-0.306,0.242,0.228,0.225,-0.218,0.178,respectively,all P＜0.05); C-RPWV was correlated with age,DBP,SBP,NO,TG (r=0.312,0.319,0.241,-0.197,0.151,respectively,all P＜0.05).Multiple regression analysis demonstrated that C-FPWV=4.640 + 0.081× HOMA IR+ 0.047× age+0.035×SBP+0.29×TG-0.017×NO+0.014×ET+0.132×hsCRP,r2=0.514; CRPWV=3.161+0.034×age+0.033×DBP+0.313×fastingBG+0.013×ET-0.013×NO,r2=0.390.Conclusions The decreases of arterial elasticity are closely related with endothelial function,insulin resistance,levels of blood lipids and hsCRP in elderly patients with hypertension.

selenomethionine.Although the structure of selenomethionine and methionine are similar,the electron supply ability of selenomethionine is lower than that of methionine.Conclusion Methionine as electrons provider could accelerate the photolysis of VB2 to generate ?O 2,but selenocystine,selenomethionine and cystine could directily scavenge ?O 2 generated by VB2.

Objective To analyze the Brucellosis incidence and to predict the trends of the disease in Shanxi province and the national in recent years,which could provide the reference for surveillance,prevention and control of the disease.Methods Brucellosis data which was reported monthly during January 2006 and December 2010 in Shanxi province and the data released by Chinese Center for Disease Control and Prevention during January 2005 and December 2010 were collected.Several indexes,such as the annual increasing number,the development rate,growth rate and other indicators were applied to compare Shanxi province with the national Brucellosis epidemic in recent years.What's more,the seasonal autoregressive integrated moving average model (ARIMA) was fitted respectively with the data of Brucellosis incident number reported monthly,so as to predict the prevalence status in the coming two years by verifying the fitting effect.Results Brucellosis prevalence of Shanxi province reached the peak in 2008,and the incidence number was 5397,which was 900 more than 2007.From the onset of decline after 2008,the prevalence decreased by 17.67％ (906/5128) in 2010.However,national incidence of Brucellosis kept increasing before 2009 and the prevalence increased rapidly from 2007 to 2008,and the growth rate reached 39.16％ (8442/21 560).Although the number of Brucellosis fell by 2041 cases in 2010 than in 2009,the rate of decline was only 5.14％(2041/37 734).The fastigium of Brucellosis was from May to July yearly whether Shanxi province or the country.The ARIMA models of Shanxi province and the nation were ARIMA [(1,0,1)(1,1,0)12] and ARIMA[(1,0,1)(0,1,1)12],respectively,according to the incidence numbers reported monthly.The fitting effect of models showed that the predicted values of the two models were both consistent with the actual situation and all predicted values fell within the 95％ confidence limits,which depicted that they both fitted well.The predicted values depict that the incidence of Brucellosis overall trend was basically stable in Shanxi province,while the numbers in the nation would increase in a small extent in 2011 and 2012.The fastigium of Brucellosis was still from May to July yearly.Conclusions Brucellosis control measures are effective in Shanxi province,incidence of Brucellosis declining.The ARIMA model could predict the number of Brucellosis well,which can provide a valuable reference for the predication and evaluation of Brucellosis epidemic in the future.

Objective To explore the effects of PP242 on the expression of apoptosis protein Bcl?2 in human lens epithelial cells(HLECs). Meth?ods Immortal HLECs SRA01/04 were cultured and treated with different concentrations of PP242. The cell growth was examined by MTT assay at 24 h and 48 h after PP242 treatment. Real?time quantitative polymerase chain reaction(RT?PCR)and Western blot were adopted to detect the mRNA and protein expression of Bcl?2 respectively. Results The cultured HLECs SRA01/04 were collected and treated with different concentra?tions(100,250,500,750,1 000,1 500 nmol/L)of PP242. After treatment for 24 h and 48 h,the inhibitory rate in each well was determined by MTT assay. The inhibition rate was as below,24 h:7.55%,9.43%,16.98%,22.64%,26.42%,30.19%;48 h:11.11%,23.81%,36.51%,42.86%, 49.21%,63.49%. Compared with the control group,the difference was statistically significant(P<0.05). Compared with the control group(0 nmol/L),the expression of Bcl?2 protein was significantly decreased with the increasing concentrations of PP242(P<0.05),while the expression of Bcl?2 mRNA was inhibited by PP242 based on the results of RT?PCR. Compared with the control group(0 nmol/L),the RT?PCR results of Bcl?2 mRNA were 0.723±0.039,0.517±0.028,0.353±0.052,0.167±0.046,respectively(P<0.05). Conclusion PP242 could inhibit cell proliferation of HLECs in vitro with a concentration and time depended manner. Bcl?2 protein is expressed in HLECs,which could be down regulated by PP242 treatment.
