OBJECTIVE:To clone,prokaryotic express and characterize the TEM-type ?-lactamase produced by Enterobacter cloacae clinical isolate EC002. METHODS: The drug susceptibility of Enterobacter cloacae clinical isolate EC002 was detected by agar double dilution,double disk screening and confirmatory test were employed to detect the ESBLs. The isoelectric point (pI) of enzyme was detected by isoelectric focusing electrophoresis (IEF),the genes were coded by PCR amplification enzyme,and the prokaryotic expression and phenotype of the TEM-type ?-lactamase were detected. RESULTS: Enterobacter cloacae EC002 were resistant to most of the ?-lactamases. Positive results were noted for the phenotype identification and plasmid conjugation test. IEF showed that Enterobacter cloacae EC002 produced two ?-lactamases with pI value at 8.7 and 5.4 respectively,which were confirmed to be CTX-M-22 and a new TEM-subtype ?-lactamase by DNA sequencing,and the phenotype of the expressed enzyme of the cloned strains was non-ESBLs. The TEM-type ?-lactamase was named as TEM-141 by GenBank. CONCLUSION: The TEM-141 produced by Enterobacter cloacae EC002 was a new type of plasmid-mediated broad-spectrum ?-lactamase.

Objective To investigate the display status of ultrasonography imaging check in central nervous system (CNS) in infants of early pregnancy and the diagnostic value of CNS malformation in infants of early pregnancy.Methods Gestational weeks of 2 751 enrolled subjects were divided according to the ultrasonic measurement of the crown rump length (CRL):11-11 +6 weeks group,12-12+6 weeks group,and 13-13 + 6 weeks group,prenatal ultrasound were performed to examine fetal CNS anatomy in infants of early pregnancy,record the display status in each groups of infants and analyze the relationship between the display situation and gestational age.Results Fourteen cases of fetal CNS malformation (20 malformations) in total were found by prenatal ultrasound,and the incidence of CNS malformation was about 5.09％ (14/2 571).Wherein,12 cases of early pregnancy were diagnosed,and 2 cases of middle pregnancy were diagnosed.The sensitivity of ultrasound of early pregnancy in the diagnosis of fetal CNS malformation was 85.71％.In the group of research,the ultrasound display ratios of 11-11+6 weeks group,12-12+6 weeks group and 13-13+6 weeks group were 96.73％,97.94％,98.06％,respectively.There was no significant difference in early pregnancy fetal CNS display ratio among groups (x2 =1.56,v =2,x2＜ x0.05.2 =5.99,P ＞ 0.05).Conclusions The display rate of CNS structure in infants of early pregnancy (11-13+6 weeks)is higher,and is not affected by gestational weeks.Prenatal ultrasound can effectively diagnose CNS severe malformation in infants of early pregnancy.

OBJECTIVETo explore the laws of anovulatory infertility patients of Gan-yin deficiency syndrome (GYDS), and to analyze the correlation between GYDS and partial sex hormones and metabolic parameters.

METHODSRecruited were 103 anovulatory infertility patients, including 48 of GYDS and 55 of non-GYDS. At the same time, 20 healthy pluripara at the child-bearing period were recruited as the control group. The body mass index (BMI) and waist to hip ratio (WHR) were measured. Serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (T), prolactin (PRL), estradiol (E2), sex hormone binding globulin (SHBG), fasting blood glucose (FBG), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and leptin were detected. The inter-group difference of the above indices was compared between the two groups.

RESULTSLevels of BMI, FINS, HOMA-IRI, leptin, TC, TG, LDL-C, T, PRL, and LH were higher in the GYDS group and the non-GDS group than in the control group (P < 0.01, P < 0.05), while SHBG was lower in the GYDS group and the non-GYDS group than in the control group (P < 0.01). Only the PRL level was higher in the GYDS group than in the non-GYDS group (P < 0.01).

CONCLUSIONSGan-yin deficiency is a predominant manifestation in anovulatory infertility patients. Partial disorder of some sex hormones and metabolic derangement might be common pathological factors for anovulatory infertility, while increased PRL levels was dominant in GYDS.

Objective To compare clinical outcomes in eyes with macula-off rhegmatogenous retinal detachments (RRD) with peripheral breaks managed by surgical protocols that result in either complete (CSFD) or partial subretinal fluid drainage (PSFD).Methods Following the clinical detection of a maculaoff RRD with peripheral retinal breaks,patients were offered the opportunity to enroll in the study,and those patients who signed the consent were evaluated for eligibility based upon the inclusion and exclusion criteria for this clinical study,and if fully eligible they were assigned prospectively to one of the two surgical designs (PSFD or CSFD,1∶ 1) using a random number table.Seventy-two eyes of 72 patients were enrolled and studied.Patients were treated with 25G plus vitrectomy,endolaser or transscleral cryopexy,either complete (n=36),or partial (n=36) subretinal fluid drainage,and 14％C3F8 (PFO) was used for intraocular tamponade.After surgery,all patients were kept in a supine position for 24 hours,and then in a clinically optimal position for 6-10 days.The study patients were examined at 1,3 and 6 months after surgery with thorough ophthalmic examinations.Macular optical coherence tomography (OCT) imaging was acquired in 1 month.Anatomical and visual outcomes as well as intra-operative and postoperative complications of the two groups were compared.Furthermore,the persistence of subfoveal fluid in OCT images and the symptoms of distortion at 3 months were measured and recorded.The primary study endpoint of anatomic retinal reattachment for each group was based upon the 6-month time-point.Results The preoperative baseline characteristics between the two groups were not significantly different.The single-operation success rates were 88.9％ and 91.6％ respectively for the CSFD and the PSFD groups (x2 =0.158,P＞0.05).The mean best corrected visual acuity (BCVA) at 6 month endpoint were 0.99± 0.52 minimum resoluation angle in logarithmic (logMAR) for the CSFD group and 1.07±0.34 logMAR for the PSFD group(t=0.580,P=0.564).The mean operative time was longer in the CSFD group (62.25± 4.32) minutes than that in the PSFD group (47.9 ± 5.0) minutes (t =0.580,P=0.564).seven of 29 (24.1％) phakic eyes in the CSFD group had lens injury during SRF drainage,and none of the 31-phakic eyes in the PSFD group sustained lens damage.Residual PFO was present in 6 of 36 CSFD cases (16.7％).Successful retinal reattachment after primary surgery was achieved in 33) PSFD eyes and in 32 CSFD eyes based upon OCT imaging at 1 month demonstrated reattached foveae with no residual subfoveal fluid.Among these patients,22 patients (62.5％) in the CSFD group and 23(69.7％) patients in the PSFD group reported distortion in the operated eye or/and a difference in image size between the two eyes at the 6 month visit (P=1.00).Conclusions Partial subretinal fluid drainage during pars plana vitrectomy for the repair of macula-off RRD with peripheral breaks is effective.The success rates are not statistically different.Additionally,PSFD procedures can simplify the surgery procedure,shorten operative time and,and to some extent,reduce the incidence of complications relevant to the CSFD approach.

Objective To breed homozygous mice of Treg-Th17 fluorescence double labeling and to investigate the role of Treg-Th17 balance in endotoxemia. Methods Mice of Treg and Th17 fluorescence single labeling were brought from Harvard Medical School,USA and were mated and bred based on the genetic rules.The genomic DNA was extracted from the tails of second generation weaning mice for genotyping by polymerase chain reaction (PCR).Thereafter,the homozygous mice of fluorescence double labeling were selected to have successive inbreeding for three generations and their genotypes and growth status were measured.The endotoxemia model in vivo was duplicated and changes of Treg-Th17 balance were detected by flow cytometry analysis at 24 h and 48 h after endotoxemia. Results Among the seven second generation mice in the first batch,only three (two males and one female) were the wanted homozygotes.Meanwhile,the genotypes of their offsprings for the next three generations were all Foxp3 RFPKI-homo IL-17A GFPKI with normal growing status.As important component of endotoxin,lipopolysaccharide (LPS)could induce significant signal expressions of red fluorescence protein (RFP) and green fluorescence protein (GFP).The ratio of CD8a + Foxp3 +,CD8a + IL-17A +,CD4 + Foxp3 + and CD4 + IL-17A + in the lymphocytes went up significantly in the group of 24 hours of LPS treatment,as compared with the control group (P ＜ 0.01 or P ＜ 0.05 ),while the difference between the control group and the group of 48hours of LPS treatment had no statistical significance (P ＞ 0.05). Conclusion Foxp3 RFPKI-homoIL-17A GFPKI mice have identical genotypes and stable genetic characteristics and is a model animal and novel research platform that can provide real-time monitoring of the changes of Treg-Th17 balance in vivo.The role of T reg-Th17 balance works significantly at 48 hous after the subject is exposed to LPS stimulation,and the roles of CD8a + Foxp3 and CD8a + IL-17A + in Treg-Th17 balance require further investigation.

Objective To investigate the effect of angiotensin converting enzyme (ACE) genetic polymorphism on the cardiovascular response to endotracheal intubation in patients with hypertension.Methods The patients with primary hypertension,ASA Ⅱ or Ⅲ,aged 54-64 yr,weighing 50-70 kg,scheduled for elective operation under general anesthesia,were enrolled in this study.Polymerase chain reaction-restriction fragment length polymorphism was used to detect the polymorphism of ACE gene.The patients were assigned into 3 groups according to their genotypes:homozygote DD group (group DD),heterozygote ID group (group ID),and homozygote Ⅱ group (group Ⅱ).Systolic blood pressure (SBP),diastolic blood pressure (DBP) and heart rate (HR) were recorded before and after induction of anesthesia,and at 0,1.5 and 5.0 min after intubation (T0-4).The rate-pressure product (RPP) was calculated.The cardiovascular events were recorded.Results In groups DD,ID and Ⅱ,40,39 and 40 cases were included in the analysis respectively.Compared with group ID,there was no significant difference in SBP,DBP,HR and RPP at T0-4 in group DD (P ＞ 0.05).Compared with groups DD and ID,SBP,DBP,HR and RPP were significantly deceased at T2,3,and SBP,HR and RPP were significantly deceased at T4 in group Ⅱ (P ＜ 0.05).The incidences of the myocardial ischemia during intubation and cardiovascular response to intubation were significantly lower in group C than in groups DD and ID (P ＜ 0.05).Conclusion ACE genetic polymorphism exerts an effect on the cardiovascular response to endotracheal intubation in patients with hypertension,and homozygote DD and heterozygote ID have the most influence.

In this study, we explored the operation options for middle cranial fossa arachnoid cysts (MCFAC). One hundred and forty-nine patients who were operated for a symptomatic MCFAC between 1993 and 2006 in our hosptial were analyzed. Follow-up time ranged from 1 y to 14 y (mean=5.4 y). All these patients were divided into three subgroups according to Galassi classification. Long-term outcome and complications were studied respectively. Fenestration (F) resulted in a more favorable long-term outcome and less complication for cysts of types I and II, whereas a favorable outcome was noted in type III patients who underwent cysto-peritoneal shunting (S). We are led to conclude that Fenestration is suitable for cysts of types I and II (Galassi classification), cysto-peritoneal shunting is better for cysts of type III.

Objective To explore the imaging features and dynamic CT findings of primary adrenocortical carcinoma and evaluating its clinical value.Methods All 11 cases patients with primary adrenocortical carcinoma confirmed by surgical pathology underwent spiral CT plain scanning and two phases dynamic enhancement scanning before operation.Contrast injection was done by using nonionic Omnipaque at a flow rate of 3 ml/s with a power injector.The CT images were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Five of 11 lesions were located in the right adrenal gland,6 in the left.The diameter of the tumors was 4.1—16.0cm with 2 cases10.0cm.The attenuation of the plain scans,two phases contrast scans was 21.9—46.7 HU(with a mean value of 35.3 HU),30.5—65.8 HU(mean value 47.1 HU),and 52.6— 97.0 HU(mean value 74.2 HU),respectively.Four were in the shape of capsule,6 reticular,1 slightly inhomogeneous masses.The irregular tumor vessels of 6 reticular masses were seen in the artery phase. Conclusion The dynamic CT features of primary adrenocortical carcinoma were obvious,dynamic SCT scans could suggest the diagnose.
