ObjectiveTo evaluate the clinical features of hyperuricemia (HUA) and relationship between serum uric acid (SUA) and metabolic syndrome (MS) in adults.MethodsData were gathered from medical examination among adults age ≥ 20 years,and totally 18 862 subjects were analyzed in this study.ResultsThe prevalence of HUA was 14.8％ (2788/18 862).The rate was 18.4％( 1926/10 445) in men,10.2％ (862/8417) in women.The prevalence of HUA was increased with age,there was significant difference among different age (P =0.000),the rate in men was higher than that in women (P ＜ 0.01 or ＜0.05 ).Compared with normal SUA Patients,the levels of body mass index(BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),total cholesterol (TC),triacylglycerol (TG) and lowdensity lipid cholesterol(LDL-C) were markedly elevated (P ＜0.01 or ＜0.05),and the level of highdensity lipid cholesterol (HDL-C) was markedly decreased in HUA patients (P ＜0.05).Stepwise regression analysis showed that BMI,SBP,DBP,fasting plasma glucose (FPG),TG,HDL-C were the independent correlation factor of SUA.The incidence of hypertension,over weight/obesity,dyslipidosis,hyperglycosemia and MS in HUA patients [24.1％ (672/2788),36.2％ (1009/2788),31.2％ (870/2788),18.0％ (502/2788),20.8％(580/2788) ] was significantly higher than that in normal SUA patients [ 18.2％ (2925/16 074),26.4％(4244/16 074),22.0％(3536/16 074),15.00(2411/16 074),17.0％(2733/16 074),P＜ 0.01 ].The level of SUA in patients with MS [ (342.3 ± 64.2 ) μ mol/L ] was higher than that of those without MS[ (319.3 ± 67.1 )μ mol/L,P =0.000].ConclusionsThe prevalence of HUA is increased with age.Multiple factors of dysbolism are clustered in subjects with HUA.There is correlation between SUA and MS.

Objective The purpose of this study was to examine the status quo of the perceptions of professional benefits in the clinical teachers of nursing,analyze the influencing factors and put forward effective measures to improve it.Methods A convenience sample of 117 nurse preceptors in 4 teaching hospitals participated by completing a two-part questionnaire the Preceptor's Perception of Benefits and Rewards Scale and a demographic questionnaire.Results The total average score of benefits and rewards to the preceptor role was(63.64±9.93) points,low than the study done by Hyrkas(2007) in American.Nurse preceptors in different nursing unit felt different benefits and rewards to the preceptor role.Medicine unit and surgical unit were higher than Pediatrics unit.The longer time of being preceptor,the higher score of benefits and rewards to the preceptor role.Conclusions The score of benefits and rewards to the preceptor role is low.Hospitals should increase support for clinical teaching program,particularly pediatrics.Nurse managers should adjust promotion opportunities,workload,rewards of nurse preceptors to meet the needs of nurses in clinical teaching and to improve teaching effectiveness.

OBJECTIVE:To comparison the clinical efficacy and safety of sitagliptin and Repaglinide in the treatment of new-ly diagnosed patients with type 2 diabetes mellitus. METHODS:214 newly diagnosed patients with type 2 diabetes mellitus were randomly divided into study group and control group with 107 cases in each group according to random number table method. Both group received routine diabetes diet,health education and suitable exercise. Control group was treated with Repaglinide tablet 1.0 mg,tid;while study group was treat with Sitagliptin tablet 100 mg,qd. Lab indexes,FBG,PBG,HbA1c and BMI were observed in 2 groups before and after treatment. ADR were compared between 2 groups. RESULTS:There was no statistical significance in lab indexes between 2 groups before and after treatment (P>0.05). After treatment,FBG,PBG,HbA1c were significantly de-creased significantly in 2 groups,with statistical significance (P<0.05),there was no statistical significance between 2 groups (P>0.05). BMI of 2 groups were increased significantly,and the study group was higher than the contrd group,with statistical sighificance (P<0.05). Patients in the study group had no hypoglycemia,while 3 patients in the control group suffered from it, there was statistical significance (P>0.05). CONCLUSIONS:Sitagliptin is similar with repaglinide in therapeutic efficacy;both can effectively reduce blood glucose of elderly patients with newly diagnosed type 2 diabetes mellitus,and the incidence of hypo-glycemia was low,the saterty was good,but sitagliptin has a better control of BMI in patients.

Objective To introduce a poisoning accident caused by clearing up the disuced bloat pool of green plums. Methods In a certain area in Fujian happened a poisoning accident in which many people poisoned. The site of monitoring was carried out immediately. Results The concentrations of hydrocyanic acid, acetonitrile, methane, and carbon dioxide were very high in the air of the pool. Conclusion The main cause of the poisoning was that the cyanogenic glycosides contained in the nucleolus of the green plums. After broken down, the cyanide was released, and then the cyanide synergistic effect with the asphyxiating gas such as methane and carbon dioxide developed also. Treated the sediment and waste water with bleaching powder and lime, cyanide had been eliminated efficiently.
