OBJECTIVE To investigate drug-resistance status and changing tendency of Escherichia coli inducing hospital infection to provide the evidence for reasonable use of antibiotics. METHODS Pathogenic bacteria were isolated and identified according to the National Clinical Laboratory Manipulation Rules. Drug resistance profile was analyzed by K-B methods. RESULTS In the four years, the resistance to seventeen common antibiotics in E. coli was on the rise. The resistance rate to ampicillin was the most highest, 90.8-94.2%. There was no strain that was resistant to imipenem and meropenem. Detection rate of extended spectrum ?-lactamases (ESBLs) producing E. coli increased from 13.2% to 32.0%. CONCLUSIONS Drug-resistance status of E. coli inducing hospital infection is very serious. We should strengthen the management of antibiotic use and control the spread and prevalence of the drug-resistant bacteria.

OBJECTIVE To investigate the distribution characteristic and drug resistance status in pathogens isolated from infected urinary tract and offer the scientific evidence for reasonable usage of antibiotics.METHODS Totally 257 strains of pathogens isolated from infected urinary tract were identified by auto-microbiological assay and antibiotic susceptibility test was performed by K-B method.RESULTS Among 257 strains,Escherichia coli accounted for 60.3%,ranking the first.Enterococci ranked the second,accounting for 10.5%.Except for 100% sensitivity to imipenem,meropenem,vancomycin and teicoplanin,the pathogens were resistant to the other antibiotics in different degrees.The detection rate of extended-spectrum beta-lactamases(ESBLs) producers in E.coli and Klebsiella pneumoniae were 40.0% and 37.5%,respectively.CONCLUSIONS The drug resistance of pathogens from infected urinary tract is on the rise.We should strengthen monitoring and controlling of it.

Objective To investigate the characteristics of clinical course in elderly patients and young-mid-dle-aged patients with upper gastrointestinal hemorrhage. Methods 417 hospitalized patients were divided into eld-edy group (≥60 yrs,198 cases) and young-middle-aged( <60 yrs,219 cases). All patients were diagnosed upper gastrointestinal hemorrhage by endoscopy. Results Endoscopy diagnosis included the first common cause to upper gastrointestinal hemorrhage was peptic ulcer, whereas more gastric ulcer were seen in elderly patients and more duo-denal ulcer were seen in young-middle-aged patients(23.7% vs 12.8%, 39.7% vs 21.7%, P <0.01). More eld-erly patients had a history of using Aspirin or NSMDs (17.1% vs 5.0%, P <0.01). The number of circulatory fail-ure and blood transfusion necessary were significantly increased, the mean duration of hospital stay was longer in eld-erly group than in young-middle-aged group(P<0.05). Conclusion The elderly patients have a more complicated clinical course than those young-mlddle-aged patients. Endoscopy is a necessary and effective method for both diagno-sis and treatment.

Objective To assess the efficacy and adverse reactions of two cconcentrations of diluted botulinum toxin A for dynamic frontotransverse wrinkles.Methods Totally 103 cases met the inclusion criteria were assigned into two groups by a random number table:high concentration group (50 U/ml,53 cases) and low concentration group (25 U/ml,50 cases).The two groups were given the local injection with 50 U/ml and 25 U/ml concentration of botulinum toxin type A,respectively.Dosage of BTX-A,the treatment effect,the duration of the effect and the incidence of adverse reactions were analyzed.Results The high concentration group were given the BTX-A (45.53±2.05) U,the low concentration group were given the BTX-A (25.71 ± 1.74) U,and the difference were statistically significant (P＜0.05).The differences of post-operative evaluation,time of onset and duration between the two groups were not statistically significant (P＞0.05).In the high concentration group,30 cases (88.24％) had forehead heaviness sensation,and 2 cases (5.71％) in the low concentration group,the difference were statistically significant (P＜0.01).Neither of the groups was given any specific treatment,the symptoms were disappeared in two weeks.In either group there was no serious complications such as intoxication,allergy,etc.Conclusions The efficacy of local injection with two concentrations of diluted botulinum toxin A in the treatment of dynamic frontotransverse wrinkles is positive,the duration of treatment effect between the two groups is similar,and therefore the 25 U/ml concentration is recommended to reduce the forehead heaviness sensation.

Gallstone disease is highly prevalent in clinic,particularly in women and some specific ethnic groups.The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile:cholesterol,bile salts,and phospholipids.Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcription factors,including nuclear receptors LXR and FXR.Human and murine genetic,pathophysiological evidence is consistent with the relevance of these nuclear receptors in gallstone formation.In addition,there is emerging data that also suggests a role for estrogen receptor ESR1 in abnormal cholesterol metabolism leading to gallstone disease.A better comprehension of the role of nuclear receptor function in gallstone formation may help doctors to design new and more effective therapeutic strategies for this highly prevalent disease condition.

Objective To study the adverse effect of omethoate on DNA in mice testicle cells in vivo.Methods 24 mice were randomly divided to 4 groups:control(no omethoate),1,2 and 4 mg/kg.omethoate was given by gavage one time a day for consecutive 7 days.DNA damage was detected by single cell gel electrophoresiss (SCGE).Results At the concentration of 1,2,4 mg/kg,omethoate induced DNA damage in mice testicle cells in vivo with an obvious dose-effect relationship(r=0.969 5).Conclusion Omethoate may cause DNA damage in mice testicle cells.

Objective To study the impact of rehabilitation training combined with low molecular heparin calcium on functional recovery and venous thrombosis of postoperative period of hip fracture in the elderly.Methods 86 elderly patients with hip fracture surgery were divided into the control group(43 cases)and observation group (43 cases)according to random number table method.The control group was given low molecular heparin calcium, and the observation group was given rehabilitation training combined with low molecular heparin calcium.After four weeks,the hip functional recovery and venous thrombosis occurrence were observed in the two groups.The levels of blood rheology indicators such as blood high shear viscosity,shear viscosity,low shear viscosity,erythrocyte aggrega-tion index and coagulant function index of thrombin time and D -dimer were detected.Results The scores of hip joint pain,joint function,joint mobility,deformity and Harris score in the observation group were higher than those in the control group,the differences were statistically significant(t =3.713,3.224,3.345,1.861 and 8.087,all P <0.05).The incidence rate of venous thrombosis in the observation group was 6.89%,which was lower than 23.26%in the control group,the difference was statistically significant (χ2 =4.440,P =0.035).After 4 weeks treatment,the levels of the whole blood high shear viscosity,shear viscosity,low shear viscosity and erythrocyte aggregation index in the observation group were lower than those in the control group,the differences were statistically significant (t =2.092,2.590,1.716 and 2.590,all P <0.05).After treatment,the level of D -dimer in the observation group was lower than that in the control group,and the prothrombin time in the observation group was higher than that in the con-trol group,the differences were statistical significance(t =7.510 and 2.151,all P <0.05).Conclusion The rehabil-itation training combined with low molecular heparin calcium can promote hip joint function recovery of postoperative period of hip fracture in the elderly,reduce the incidence of venous thrombosis,improve blood rheology and blood coagulation function indicators.
