OBJECTIVE To investigate the drug resistance of Escherichia coli in biliary tract infection and genotype of ESBLs.METHODS Antimicrobial susceptibility test was performed using Kirby-Bauer method.The genotypes of ESBLs were detected by PCR.RESULTS The detection rate of ESBLs producing bacteria was 32.4%(23 strains),and the drug-sensitivity test indicated that E.coli was sensitive to imipenem,meropenem and cefoperazone/subactam,but these ESBLs producing strains were resistant to other antimicrobial agents.ESBLs were identified as TEM type in 16 strains,SHV type in 4 strains,CTX-M type in 12 strains and OXA type in 5 strains.CONCLUSIONS ESBLs-producing E.coli in biliary tract infections show strous resistance.TEM and CTX-M are the most common ESBLs genotypes.

Objective To explore the behavior characteristics in children with benign epilepsy combined with centro-temporal spikes(BECTS).Methods Eighty-two children with BECTS aged 2.5-3.0(2.65?2.31)years old,51 male,31 female,who were free of mental retardation assessed with Gesell developmental schedules,untreated with antiepileptic drugs,and were investigated 15 days after the latest seizure.Eighty-two healthy children with sex and age matched to the cases,53 male,29 female,aged 2.5-3.0(2.6?0.4)years old.The behavior characteristics of infants in BECTS group and control group were assessed with CBCL,including 6 behavior factors which were sleep problem,social flinches,depression,physical aspect,attacking,act of sabotage and the infants-middle school student social ability scale.Results The total scores of behavior characteristics and the scores of depression,sleep problem,attacking and act of sabotage in BECTS group were all higher than those in control group,the differences were statistically significant.However,scores of social flinches,and physical aspect in BECTS group had no significant differences compared with those of control group.There were no significant difference of social adaptive component between the BECTS and control group.Conclusions Children with BECTS have behavior disorders to some extent,but their social adaptive capacity are the same as normal children.

A total of 1342 individuals underwent physical examinations according to the criteria of metabolic syndrome of International Diabetes Federation (IDF) in 2005.And 314 patients with metabolic disorders were screened for diabetes by standard meal and methods oral glucose tolerance test (OGTT).Newly diagnosed diabetics was 12 (4.1% ) vs.17 (5.8%) respectively.No significant difference existed between two methods (P =0.332).Kendall's (τ)b =0.313,Kendall's (τ)c =0.208 and Gamma coefficient =0.580 (P =0.000).The mixed meal method was correlated with OGTT,Kappa =0.258 (P =0.000) and two methods were consistent.Diabetic screening should be stressed in the subjects with metabolic abnormalities.And the detecting efficiency of postprandial plasma glucose is similar to OGTT.

Objective To observe effects of ginsenoside Rb1 on phosphorylation of microtubule-associated protein 2 (pMAP-2) in hippocampus and amygdala of depressive model rats. Methods Thirty male Wistar rats were randomly divided into control group, model group and treatment group. The depression rat model was produced by giving chronic unpredicted mild stress (CUMS). Treatment group was given daily intragastric administration of ginsenoside RB 1 (1 g/mL crude drug, 1 mL/100 g body weight) for 22 days during modeling. Western blot assay was used to detect expressions of MAP-2 and pMAP-2 protein, and real-time PCR was used to detect expressions of pMAP-2 mRNA respectively. Results The expressions of pMAP-2 protein and mRNA in hippocampus and amygdala were significantly lower in model group than those of control group (P < 0.05). The expressions of pMAP-2 protein and mRNA were significantly higher in treatment group than those of model group (P<0.05). Conclusion Ginsenoside Rb1 can play anti-depression role by inhibiting the phosphorylation of MAP-2 in rats.

Objective To investigate the effects of ursolic acid (UA) on cisplatin (CDDP)-induced expres_sion of transient receptor potential vanilloid 1 (TRPV1) in mouse cochlea .Methods Sixty BALB/c mice were ran_domly divided into 4 groups (15 mice in each group) and received introperitoneal injection once daily for 5 days:Control group (normol saline) ,UA group (80 mg/kg/day) ,CDDP group (4 .5 mg/kg/day) ,and CDPP (4 .5 mg/kg/day) plus UA group (80 mg/kg/day) .The expression of TRPV1 in mouse cochlea was determined by immuno_histochemistry ,microscope image analysis and western blot ,and auditory thresholds were evaluated by auditory brainstem response (ABR) measurement .ResuIts The expression of cochlea TRPV1 and ABR threshold shift was significantly increased in the mice treated with CDDP (P< 0 .05) ,as compared with control mice .These effects were prevented by UA treatment (all P<0 .05) .Furthermore ,a linear relationship analysis revealed that the ex_pression of cochlea TRPV1 was significantly correlated with ABR threshold shift(|r|>0 .7 , P<0 .05) .ConcIusion UA effectively attenuated CDDP -induced ototoxicity and improved auditory function through inhibition of TR_PV1 .

A quail-origin subtype of the influenza virus was isolated from a human-infecting H7N9 subtype of the avian influenza virus found in a live poultry market and was given the name A/Quail/Hangzhou/1/ 2013 (H9N2). We analyzed the whole genome of this virus and its biologic characteristics. Sequence analyses suggested that the: HA and NS genes belonged to a CK/BJ/1/94-like lineage; NA, NP, PA and PB1 genes belonged to a SH/F/98-like lineage; M and PB2 genes belonged to a G1-like lineage. Analyses of key amino acids showed that the cleavage site in HA protein was PSRSSR ↓ GL, and that the HA protein had a human receptor-binding site with Leu226. Deletion of amino acids 69 - 73 was detected in the stalk of NA protein, the M2 protein had an Asn31 mutation, and the NS1 protein had two mutations at Ser42, Ala149. The intravenous pathogenicity of this virus was 0.36. A study in chickens suggested that all inoculated birds shed the virus from the trachea and cloaca on the third day post-infection (p. i. ) until 11 days. All chickens that had direct contact shed the virus on the second day p. i. until 8 days. Results of virus reisolation suggested that lung and tracheal tissues could shed the virus in 5 days, whereas the other organs could shed the virus in 3 days. These results suggest that this virus strain is H9N2 subtype LPAIV, whose lineage is prevalent in mainland China. This research provides evidence on how to monitor and prevent the H9N2 subtype of the avian influenza virus.
