Objective To investigate the progress and effectiveness of water-improving defluoridation projects comprehensively in control of fluorosis in drinking-water-borne endemic fluorosis areas in Hubei Province,and to provide a scientific basis for making strategies in prevention and control of endemic fluorosis.Methods All villages affected by fluorosis in drinking-water-borne endemic fluorosis areas were selected in Hubei Province,in which the progress and effectiveness of water-improving and defluoridation projects were investigated in 2015.Those villages were chosen to determine fluoride content of drinking water,and to check the prevalence of dental fluorosis of children 8 to 12 years old.Water fluoride content was tested with fluoride ion-selective electrode,and dental fluorosis was diagnosed by the Dean method.Results The water improvement projects were completed in 197 villages in the 30 disease affected counties (cities) with accomplishment rate 100.00％ (197/197),geometric mean of water fluorine 0.36 mg/L,qualified rate of water fluorine 100.00％ (197/197) and normal operation rate of the water-improvement projects 95.94％ (189/197).Totally 14 856 children aged 8-12 were examined their dental fluorosis.The prevalence rate was 1.78％ (265/14 856) and the dental fluorosis index was 0.04,which meant epidemic strength was negative.Totally 29 out of the 30 disease affected counties (cities) had met the disease control standards.Conclusion The prevalence of drinking-water-borne endemic fluorosis in Hubei Province has been under control,but management and monitoring of the water improvement projects still should be strengthened.

OBJECTIVE:To provide reference for clinical application of antibiotics and the management of pathogen. METH-ODS:The clinical isolated bacteria in our hospital from 2011 to 2014 were identified and analyzed,and the amount of antibiotics in our hospital from 2011 to 2014 were analyzed. The operation and result of drug susceptibility test were in accordance with the standard of clinical laboratory standards institute(CLSI),using WHONET software for statistical processing. RESULTS:The main bacteria isolated in our hospital during 2011-2014 were as follows:constituent ratio of Escherichia coli were 14.93%,16.81%, 15.01% and 15.41%,respectively;that of Staphylococcus aureus were 9.84%,11.90%,9.83% and 7.17%,respectively;that of Acinetobacter baumannii were 9.00%, 9.95%, 14.24% and 18.64%, respectively;that of Pseudomonas aeruginosa were 12.36%,12.42%,14.20% and 15.48%,respectively. The main antibiotics used in our hospital during 2011-2014 were as fol-lows:the amount of piperacillin/tazobactam(2.25 g/a)were 4 685,12 610,13 639 and 14 542,respectively;that of cefepime (0.5 g/a)were 8 613,24 738,12 684 and 6 751,respectively;that of aztreonam(0.5 g/a)were 14 124,32 062,3 323 and 4 534,respectively;that of meropenem(0.5 g/a)were 2 291,5 436,6 813 and 5 341,repectively;that of levofloxacin(0.3 g/a) were 12 253,40 893,48 468 and 50 558,respectively. CONCLUSIONS:With the increase of antibiotics,susceptibility rate of main pathogen are gradually decreased;rational use of antibiotics plays an important role in decreasing the drug resistance.

Objective To investigate the effect of minocycline on isoflurane-induced hippocampal neuroapoptosis and cognitive dysfunction in aged rats. Methods Forty-five male SD rats were randomly assigned into 3 groups ( n=15): blank control group ( group C) , 1.5% isoflurane group ( group I) and 50 mg??kg-1 minocycline+1.5% isoflurane group ( group M+I) . Minocycline was injected intraperitoneally 12 h before the start of anesthesia for group M+I.Group I and group M+I were exposed to 1.5% isoflurane for 4 h, while group C were exposed to 30% O2-70% N2.At the end of anesthesia, five rats in each group were randomized to analyse arterial blood gas. The other rats in each group were sent back to their home cage until they were fully awake.Fourteen days after anesthesia, Morris water maze was used to assess the cognitive function, and then hippocampi of rats were dissected for detection of the expression of cleaved caspase3, Bax and Bcl-2. Results No difference was found in arterial gas analysis among the 3 groups (P>0.05).Compared with group C, the rats in the group I spent more time locating the platform on the third and fourth training days and the time percentage that the rats in group I spent in the target quadrant was much less (P<0.05).However, these changes were reversed in group M+I (P<0.05).The isoflurane-induced increased level of Bax and cleaved caspase3 and decline of anti-apoptotic factor Bcl-2 were restored by minocycline pretreatment ( P<0.05) . Conclusion Minocycline could attenuate cognitive dysfunction induced by isofluranein aged rats.The mechanism is associated with inhibition of hippocampal neuroapoptosis which is increased by isoflurane.

Objective Through the dynamical monitoring of the water improvement projects operation,we intend to understand the prevalent trends of endemic fluorosis of children aged 8 to 12 in Hubei,to evaluate the effect of control measures and to provide the basis for making preventive measures.Methods In Hubei,ten surveillance counties were selected,and three epidemic villages were selected as fixed monitoring villages in each county from 2010 to 2014.In those villages,the operation situation of water improvement projects and the fluoride content in drinking water were detected,and the dental fluorosis of children aged 8 to 12 was diagnosed.Results From 2010 to 2014,the normal operation rate of water improvement projects was 75.61％-100.00％,the average of water fluorine content did not change,the differences were not statistically significant (F =2.00,P ＞ 0.05).The numbers of water improvement projects with water fluorine content in excessive amount was increased in the past five years which was only one project in 2010-2012 and was increased to two projects in 2013 and 2014.In 2010-2014,the dental fluorosis prevalence rate of whole children was 9.45％ (525/5 557),the dental fluorosis prevalence rate of exceeding-standard villages of water fluoride content was 42.40％ (92/217),the dental fluorosis prevalence rate of qualified villages was 8.11％ (433/5 340).The children's dental fluorosis prevalence rate of exceeding-standard villages of water fluoride content was higher than that in qualified villages;the differences were statistically significant (x2 =282.60,P ＜ 0.05).Conclusions The operation rate of water-improving projects is mostly higher than 90％,and so is the qualification rate of fluoride content in drinking water.The operation condition and water quality of the water-improving projects in Hubei need to be improved.The prevalence of children dental fluorosis of affected villages has dropped significantly after low fluoride water is provided continuously.

Objective To investigate the diagnostic value of serum human epididymis protein 4 (HE4 ) for ovarian cancer . Methods Electrochemiluminescence immunoassay was employed to detect the serum HE 4 of 91 patients with ovarian cancer (ovari-an cancer group) ,69 patients with benign ovarian disease(benign group) and 60 healthy people(control group) .Area under the curve(AUC ) of receiver operator characteristic (ROC ) curve for HE4 was calculated .Results Serum HE4 level [(146 .81 ± 81 .29)pmol/L] of patients in ovarian cancer group was significantly higher than those in control group [(43 .16 ± 25 .64) pmol/L] and benign group[(59 .86 ± 39 .87) pmol/L](P<0 .01) .Set serum HE4≥140 pmol/L as positive cutoff value ,the diagnostic sensi-tivity of serum HE4 detection for ovarian cancer was 82 .4% (75/91) ,specificity 89 .9% (62/69) and diagnostic efficiency 85 .6% . Serum HE4 levels of patients with serous adenocarcinoma ,endometrial adenocarcinoma or other ovarian cancer were markedly high-er than that with mucinous adenocarcinoma (P<0 .01) .Serum HE4 levels of patients with stage Ⅲ ,Ⅳ ovarian cancer were obvious-ly higher than those with Ⅰ ,Ⅱ stage(P<0 .01) .Conclusion HE4 detection has clinical value for the auxiliary diagnosis of ovarian cancer .

Objective: To analyze the association of thrombocytosis with the prognosis of patients with gastric cancer.Methods: The clinical materials of 782 patients with gastric cancer who underwent initial surgery in our hospital between January 1995 and December 1999 were retrospectively analyzed.Kaplan- Meier and Log-Rank test were used to analyze the data.Prognostic factors were analyzed by multivariate Cox proportional hazards model.Results: Thrombocytosis oc-curred in 11.4% (87/782) patients.The platelet level was not significantly different among patients of different gender, tumor stage, and histological differentiation (P>0.05).However, a significant difference was observed in the platelet level among patients with different age and surgical approach (P<0.05).The 1-, 3-, and 5-year survival rates were 75.0%, 40.1% and 28.9% in patients without thrombocytosis and 52.8%, 16.9%, and 13.5% in patients with thrombocytosis (P=0.002).Univari-ate analysis showed that histological differentiation, pathological stage, surgical approach and thrombocytosis significantly affected the survival of patients.While age and gender had no significant impact on patient survival.Multivariate analysis showed that pathological stage, surgical approach, and thrombocytosis were independent prognostic factors for gastric can-cer.The relative risk of death of patients with thrombocytosis was elevated by 1.454 times (RR=1.454, 95% CI: 1.135～1.861, P=0.005).Conclusion: Thrombocytosis is an independent prognostic indicator for the survival of initially treated pa-tients with gastric cancer.
