Objective To understand the Oncomelania hupensis snail distribution in the working areas of Yangtze River hy?drologic agencies located in the middle and lower reaches of the Yangtze River in 2016,so as to provide the evidence for assess?ing the risk of schistosome infection of hydrological workers and establishing the control strategies. Methods The suspicious en?vironments with O. hupensis snails in the above working areas were selected as study areas,and the snail situation was surveyed by the system sampling method combined with the environmental sampling method. The survey data were collected and analyzed statistically. Results Totally 19 working areas from 17 hydrological agencies were selected as the investigation sites,among which,10 working areas from 9 agencies were found with O. hupensis snail distribution. The constituent ratio of the areas with snails reached to 38.81%of the investigation areas,the occurrence rate of frames with snails was 3.08%,and the average densi?ty of living snails was 0.07/0.1 m2. By comparison,the average density of living snails and occurrence rate of frames with snails in hydrological agencies under the jurisdiction of the Middle Reaches Administrative Bureau were the most serious among three administrative bureaus of the Yangtze River Water Resources Commission. Conclusions There are various degrees of O. hupen?sis breeding in the working areas of hydrological agencies located in the middle and lower reaches of the Yangtze River ,and the hydrological workers are facing with the risk of schistosome infection.

Objective To construct the recombinant plasmid containing human filaggrin gene,purify and identify the immunoreactivity of the recombinant protein,and establish the indirect ELISA to detect AFA for diagnosis of RA.Methods The constructed plasmids were transformed into E. Coli Rosettagami(DE3).This fusion protein was purified by NAT chromatography.ELISA coated with the fusion protein Was established to detect the AFA in serum of patients,which included 114 cases of RA,56 cases of SLE,32 cases of OA and 40 cases of normal controls. The correlation between the results of AFA and anti-CCP in RA group were compared. Results 321 bp fragment of filaggrin gene was amplified and the recombinant expression vector pET-28a( + )-filaggrin was constructed. The sequence of filaggrin gene was the same as the sequence reported in the literatures. The Rosetta-gami (DE3) strains of E. Coli with recombinant vector showed high level of filaggrin protein after induction. The SDS-PAGE showed that the plasmid expressed the filaggrin fusion protein with molecule weight of 14 000 Da. The expression protein could be purified by Ni-NAT with activity. The absorbance value of AFA in RA group was 0.473 ±0. 248 while they were 0. 160 0. 088, 0. 121±0. 070, 0.050 0. ±018 in SLE, OA and normal groups respectively. There were significant differences of absorbance values of AFA between RA and SLE, OA, control group (t = 12.004, 14. 464, 18.078, P<0. 01, respectively). The positivities of anti-filaggrin in RA, SLE and OA were 48.2%, 5.4% and 3. 1% respectively. The positivities of AFA were significantly different between RA, OA and normal control groups (x~2 = 67. 088, P < 0. 01). There was positive correlation of results between AFA and anti-CCP antibody (r = 0.42, P < 0. 05 ) . The consistency rate of results between AFA and anti-CCP was 70. 1%. Anti-CCP was negative in 10 out of 114 patients with AFA positive. AFA can be used to diagnose RA with sensitivity of 48. 2% , specificity of 96.9% , positive predictive value of 93. 2% and negative predictive values of 67. 9% . Conclusions The purified human filaggrin fusion protein is successfully purified. The indirect ELISA method based on the recombinant protein shows good sensitivity and specificity. Joint detection with AFA and anti-CCP can improve the positive rate of detection.

ObjectiveTo compare the efficacy and safety of intermittent patient-initiated single-dose antibiotic prophylaxis and continuous antibiotic prophylaxis for the prevention of recurrent urinary tract infection (UTI) in postmenopausal women. MethodsA randomized controlled clinical trial was conducted for the prevention of recurrent urinary tract infection. Single dose of antibiotic was given every night in continuous antibiotic prophylaxis group and every time after exposure to conditions predisposed to UTI in intermittent antibiotic prophylaxis group. The duration of prevention was 12 months in both groups. ResultsThe effective rates of intermittent antibiotic prophylaxis and continuous antibiotic prophylaxis were 71.0% and 81.8% respectively (P＞0.05). The incidence of gastrointestinal adverse reaction in intermittent antibiotic prophylaxis group was significantly lower than that in continuous antibiotic prophylaxis group (7.7% vs 28.6%,P＜0.05). ConclusionsCompared with continuous antibiotic prophylaxis, intermittent patient-initiated single-dose antibiotic prophylaxis is a better prophylaxis with less gastrointestinal adverse reactions for the prevention of recurrent urinary tract infection in postmenopausal women.
