Objective To compare the risk factors of mild hemorrhage and diiferences of TOAST type in patients with acute cerebral infarction (ACI) and transient ischemia attack (TIA).Methods Forty patients with mild hemorrhage were divided into ACI group(24 cases) and TIA group(16 cases) according to disease classification.Risk factors such as age,blood pressure,blood lipid and so on between 2 groups were compared,TOAST subtype differences of 2 groups were compared.Results The age [(73.3 ± 4.1) years],the ratio of hypertension [95.8％(23/24)],leukoaraiosis [70.8％(17/24)] in ACI group was significantly higher than that in TIA group [(65.5 ± 5.6) years,13/16,9/16],there was significant difference (P ＜ 0.05).The ratio of large-artery atherosclerosis and cardioembolism in ACI group [75.0％ (18/24) and 16.7％ (4/24)] was significantly higher than that in TIA group (8/16 and 1/16),there was significant difference (P ＜ 0.05).But the ratio of small artery occlusion in ACI group [8.3％ (2/24)] was significantly lower than that in TIA group (7/16),there was significant difference (P ＜ 0.05).Conclusion Correlative risk factors of milde hemorrhage in ACI and TIA patients have significant differences.

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 To investigate the safety and feasibility of electrocoagulation of gallbladder artery in laparoscopic cholecystectomy ( LC) . Methods A total of 376 patients with gallbladder benign diseases underwent LC in our hospital from May 2004 to September 2013.The gallbladder artery was treated by electrocoagulation . Results Because of unclear gallbladder triangle due to abdominal adhesion , conversion to laparotomy was performed in 9 patients.In the remaining 367 patients, three-port LC with electrocoagulation of the gallbladder artery was conducted successfully .Laparoscopic appendectomy was conducted simultaneously in 12 patients.An additional fenestration and drainage of the left renal cyst was performed in 1 patient.Postoperatively, a secondary bile duct exploration was conducted in 1 patient because of bile duct obstruction caused by common bile duct stones . Conclusion The electrocoagulation of gallbladder artery is safe and feasible in LC for the treatment of gallbladder benign diseases .

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 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.

Objective:To measure the effect of disinfection on dimension stability of four high polymer impression materials which were separately immersed in 20 ml/L glutaraldehyde solution.Methods:Fifteen plaster replication models of four high polymer impression materials(Impregum Penta polyether, Express-Putty silicone, Silagum-Putty silicone, GC EXAFINE silicone) were made on the same metal master cast respectively. Vertical and horizontal dimensions between landmarks on the masters and plaster casts were measured with an optical microscope,one-way ANOVA was used to compare the measurements among the materials.Results:The difference between the masters and Casts in horizontal distances measured on Express-Putty silicone impression material produced models was longer than those on other high polymer impression materials produced ones after disinfection for 20 minutes and beyond clinical requirement. Compared with metal master cast, the difference became significant when these four silicone impression materials were disinfected for 40 minutes. Conclusion: Among the four kinds of impression materials, the Express-Putty silicone material is relatively the most accurate one after disinfection for 20 minutes.

OBJECTIVE: To confirm the feasibility of target-controlled infusion of midazolam on conscious sedation for patients undergoing combined spinalepidural anesthesia and the needed target-controlled blood concentration.METHODS: Sixty patients undergoing combined spinal-epidural anesthesia were subjected to target-controlled infusion of midazolam.The level of sedation of midazolam was evaluated applying OAA/S score and bispectral index(BIS).The correlation between target-controlled blood concentration(Cp) and BIS was determined.The Cp,BIS,MAP,HR and SpO2 at different OAA/S were observed. RESULTS: When OAA/S score was 3,the required target-controlled blood concentration of midazolam was(122.8? 20.8) ng? mL-1 in midazolam sedation patients.There was a good correction between BIS and Cp,and BIS=— 3.28Cp+ 355.22(r=— 0.862 5,P

[Objective] To explore the effects of mycocide and insecticide on indoor air quality in archives.[Methocls] The levels of camphor, formaldehyde and 2, 2-dichlorovinyldimethyl phosphate (DDVP) in indoor airwere determined in 17 archives. [Results] The average concentration of camphor in indoor air was 1.00mg/L inarchives applying synthetic camphor, 0.74 mg/m3 in archives applying commercialized mycocide (the main compo-nents were synthetic camphor and pyrethrin ), and 0.14 mg/m3, applying natural camphor. The concentrations offormaldehyde reached 0.297 mg/m3 at the 10th day after the co-fumigation by formaldehyde and DDVP. At thesametime, DDVP was not found in indoor air of archives.[Conclusion]The pollution of formaldehyde and camphorin indoor air of archives should be paid more attention to.
