Objective To investigate the detection of IMP andVIM metallo-β-lactamases (MβLs)genes in clinically iso-lated gram-negative bacteria as well as bacterial resistance toβ-lactam antimicrobial agents.Methods 113 clinically isolated bacteria were performed antimicrobial susceptibility testing by Kirby-Bauer method ,drug-resistant genes IMP and VIM were detected by polymerase chain reaction (PCR),PCR products were sequenced and aligned with BLAST software. Results VIM gene was detected in 1 Pseudomonas fluorescens strain ,IMP gene was detected in 15 strains ,they were Klebsiella pneumoniae (n=6),Acinetobacter baumannii (n=3),Escherichia coli (n=2),Ralstonia picket-tii (n=1),Pseudomonas aeruginosa (n=1 ),Citrobacter amalonaticua (n=1 ),and Enterobacter cloacae (n=1 ). BLAST results showed that VIM gene was VIM-2 subtype,similarity with gene bank was 99%;all IMP genes were IMP-1 subtype,which were highly homologous ,similarity was 98%-99%.Resistant rates of IMP positive strains to ceftriaxone,cefotaxime,cefoxitin,aztreonam and imipenem were all significantly higher than negative strains (all P <0.05).Conclusion IMP genes of different strains are highly homologous,all are IMP-1 type,indi-cating that IMP genes are highly transmissible and can spread among different species of bacteria.IMP genes are related with resistance ofβ-lactam antimicrobial agents.

Objective To investigate the efficacy and tolerability of estradiol (E2) gel with postoperative patients of moderately severe ovarian endometriosis cyst,who suffer from the side effect of GnRH agonist.Methods Sixty samples were selected with stage Ⅲ ～ Ⅳ ovarian endometriosis after conservative operation by the same operator at the Department of Gynecology,Xiangya Hospital,Central South University,between February 2013 and August 2014.All of the patients after surgeries were randomly divided into three groups:control group (n =20) with only goserelin injection after conservative surgery,treatment group A (n =20) who received estradiol gel,and treatment group B (n =20) who received tibolone as an add-back therapy.The serum E2,follicle stimulating hormone (FSH),luteinizing hormone (LH),hypoestrogenic symptoms,the incidence of uterine bleeding,and the recurrence after conservative operation were compared among three groups.Results Three months later aster treatment with goserelin,the serum level of E2 of three groups showed statistically significant difference (P ＜ 0.05).Serum E2 level of treatment group A was not significantly higher than treatment group B (P ＞ 0.05).The kupperman sore,the incidence of hot flashes sweating,tiring,and agrypnia of treatment groups A and B were significantly lower than the control group (P ＜ 0.05).The incidence of uterine bleeding and recurrence dont differ sharply among three groups (P ＞ 0.05).Conclusions GnRHa combined with estradiol gel can improve symptoms of postoperative patients,reduce side effects effectively,and avoid increase of the risk of vagina bleeding and relapse.

Objective To investigate the early changes of cardiac output and vital signs in term neonates shortly after born from gestational diabetic women.Methods From January 2015 to April 2015, 22 term neonates of gestational diabetes mellitus (GDM) women with euglycemia during pregnancy (GDM group) and 20 term neonates of non complicated gravidas (control group) in Shanghai First Maternity and Infant Hospital were enrolled.Neonates in both groups were measured by ultrasonic cardiac output monitor (USCOM) for cardiac hemodynamics index, including aortic peak flow velocity, pulmonary artery peak flow velocity, left cardiac output, right cardiac output and Smith Madigan inotropy index at one and two hours after birth.Vital signs including heart rate, respiratory rate, blood pressure and peripheral blood glucose were measured as well.Two independent sample t-test and Chi square test were used for statistical analysis.Results The peripheral blood glucose of neonates in GDM group was significantly lower than that of the control [(3.0±0.4) vs (4.0± 0.4) mmol/L, t=8.400, P ＜ 0.01), but all within normal range.Vital signs including heart rate, respiratory rate, mean blood pressure showed no differences between the groups (all P ＞ 0.05).In GDM group, aortic peak flow velocity were (1.230±0.160) and (1.210±0.220) m/s, left ventricle cardiac output was (0.867±0.196) and (0.859±0.193) L/min, Smith Madigan inotropy index was (0.846±0.180) and (0.823±0.189) W/m2 at one and two hours after birth, respectively, which were significantly higher than those in the control group [aortic peak flow velocity: (1.080±0.130) and (1.090± 0.120) m/s;left ventricle cardiac output: (0.754±0.098) and (0.757 ± 0.099) L/min;Smith Madigan inotropy index: (0.746 ± 0.097) and (0.725 ± 0.086) W/m2;t=3.464, 2.265, 2.296, 2.187, 2.263 and 2.202, respectively, all P ＜ 0.05].But no statistically significant differences was found on pulmonary artery peak flow velocity and right cardiac output between the two groups.Cardiac hemodynamics index had no difference between one and two hours within each group (all P ＞ 0.05).Conclusion The left ventricular contractility and left cardiac work are increased in neonates of gestational diabetes mellims women with good sugar control during pregnancy.

The development, application and revision of the clinical practice guideline (CPG) in traditional Chinese medicine (TCM) are a whole thing. However, the development and revision of TCM CPGs have been influenced due to lack of TCM CPGs reporting and feedback channel. Therefore, during the TCM standardization network establish-ment, we studied the application model of TCM CPGs with spontaneous reporting network, in order to provide the ba-sis for further TCM CPGs development and revision.

Objective To analyze the clinical characteristics,diagnosis and the surgical treatment experience of the pulmonary sequestration.Methods The clinical data from 26 patients with pulmonary sequestration undergoing surgical operation were reviewed and analyzed retrospectively.Results Pulmonary sequestration was diagnosed in 16 out of 26 patients before the operation with the diagnosis rate of 61.5%(16/26).Pre-operation chest X-ray and plain CT-scan were performed in 26 cases.Enhancement CT scanning and CTA imaging were performed in 8 cases, magnetic resonance imaging were performed in 5 cases.21 patients with intralobar sequestration underwent lobectomy and 8 patients with extralobar sequestration underwent local lesion resection.Abnormal supply arteries were intraoprat-ibely found in 21 cases originating from the thoracic main artery,3 cases from the celiac artery,2 cases from the dia-phragm artery.Smooth recovery was achieved in all patients.No peri-operative death occurred.Symptoms disappeared were followed-up for 6 months.Conclusion Enhancement CT scanning,CTA imaging and magnetic resonance ima-ging ( MRI) may improve the diagnosis of pulmonary sequestration.Operation is a safe and effective method for the treatment of pulmonary sequestration.But intraoperative abnormal blood supply arteries should be paid attention to the treatment and prevention of intraoperative and postoperative bleeding.

Objective To investigate the association between high-risk types of human papillomavirus (HR-HPV) load and the expression of nestin in different cervical lesions.Methods The hybridization capture Ⅱ (HC-Ⅱ) assay was used to test the HR-HPV load from 60 patients who were the first time to do the cervical cancer screening in Xiangya Hospital,and immunohistochemistry was used to detect the expression of nestin in those biopsy tissue samples.Results (1) The lgHPV level (logarithm of HR-HPV load) in the high level lesion group was higher than the low level one (P ＜0.05),and HR-HPV load was positively associated with the degree of cervical lesions (rs =0.269,P =0.037).(2) The expression of nestin in A group was weaker than groups B and C (H =7.271,22.843,P ＜0.01),and the expression of nestin in C group was stronger than B group (H =7.270,P ＜0.01),and the expression of nestin was positively associated with the degree of cervical lesion (rs =0.646,P =0.000).(3) The HR-HPV load was positively associated with the expression of nestin (P ＜ 0.05).Conclusions The HR-HPV load and the expression of nestin are closely related to the cervical lesions,and the joint detection has a referential value for early prevention of cervical lesions and prediction of progress of cervical precancerous lesion.It might guide the early prevention and treatment of cervical cancers.

Objective To explore clinical value of serum carcinoembryonic antigen (CEA) rate in early evaluation of imaging tumor efficacy and prognosis of disease control for advanced non-small cell lung cancer (NSCLC) before and after the second course of chemotherapy, and provide the basis for clinical adjustment chemotherapy regimens.Methods Patients in the Third Affiliated Hospital of Sun Yat-sen University were randomly collected in January 2007-September 2014 during the pathological diagnosis of 130 cases for advanced NSCLC, who had an elevated serum CEA level, including pre-chemotherapy and prochemotherapy, were collected.Receiver operating characteristic (ROC) was used to evaluate efficacy of CEA change in evaluation of early disease control (DC).SPSS 18.0 was used to analyze the relationship between CEA change and prognosis.Results After two chemotherapy cycles, the area under the ROC curve was 70.6％.When the cut-point of the change rates of CEA levels was 2.05％ , the Youden index reaches the maximum.Adenocarcinoma group and squamous cell carcinoma patients after 2 courses of CEA change rate evaluation, which area under the ROC curve was 72.0％ (95％ CI :61.4％ ～ 82.5％), and 70.1％ (95％ CI:45.8％ ～94.5％).Survival was analyzed with the Kaplan-Meier method, which showed the change rates of CEA levels were all the influencing factors of progression-free survival (PFS) in patients with advanced NSCLC(P ＜ 0.05).While the change rates of CEA levels were not predictive overall survival (OS) (P =0.715).Conclusions It prompts effective chemotherapy, and patients have the extended PFS, when CEA levels before and after chemotherapy dropped to a certain degree.
