Current reform of higher medical education focuses on curriculum integration and corresponding reconstruction of teaching system. Chongqing Medical University has carried out the reform of medical personnel training mode from basic to clinical, which has achieved certain results. Three aspects including teaching content, teaching methods and appraisal system of the urogenital system curriculum integration are introduced in the paper. In the teaching content, the parts related to urogenital system in basic subjects and clinical subjects are extracted and integrated. In the process of teaching implementation, a teaching team is set up across departments and multidisciplinary joint teaching is carried out. In order to arouse the enthusiasm of students, inspire and cultivate students' scientific research thinking by improving teaching methods, several teaching methods such as case introduction teaching method, question discussion and debate meeting are used. Scientific evaluation system is used to observe and record the whole process of students' learning. Meanwhile, some existing problems and solutions of curriculum integration are discussed in the paper to provide references for peers in relevant colleges and universities.

Objective To characterize the antibiotic resistance,homology and carbapenemase genotypes of imipenem resistant Acinetobac1ter baumannii isolated from our hospital,and analyze the clonal relatedness of the test strains.Methods Ninety five strains of imipenem resistant A.baumannii were isolated from August 2003 to December 2004 in the First Affiliated Hospital, College of Medicine,Zhejiang University.The MICs of 16 antimicrobial agents against these strains were determined by agar dilution and E-test method.The homology of these isolates was analyzed by pulse-field gel electrophoresis(PFGE).The coding gene of carbapenemases was amplified.PCR products were purified,cloned and sequenced.Plasmid DNA was extracted and purified.Conjugation and Southern blot were performed to locate the position of oxa 23 gene.Results The resistance rates to ampicillin-sulbactam and cefoperazone sulhactam were 67.9% and 30.2%.Polymyxin E had the lowest resistance rate of 17%. The resistance rate to other antimicrobial agents was higher than 90%.The 95 strains,isolated from 10 clinical units,were classified into 6 clones.Clones A and B were predominant clones.All strains produced carbapenemases which were confirmed as OXA 23 by PCR and sequencing analysis.No plasmid was extracted and conjugation was not successful.Southern bolt showed that oxa-23 gene was located on Apal-digested chromosomal segments about 220 kb and 200 kb in Clones A and B,re spectively.Conclusions OXA 23-producing A.baumannii has become one of the most important multi-resistant pathogens in our hospital.Clones A and B have widely spread in our hospital.Oxa-23 gene is located on chromosomal DNA.

Objective To investigate the resistant mechanism of imipenem-resistant K. pneumoniae.Methods The minimal inhibitive concentrations (MICs) of the antimicrobial agents were determined by Etest.Isoelectric focusing electrophoresis (IEF),plasmid extraction,conjugation, transformation,PCR amplification,cloning and sequencing were carried out for analyzing the encoding gene of ?-1actamases.Results Three kinds of ?-1actamases were detected with pIs of 7.2,6.7,and 5.4.in a clinical strain of K.pneumoniae.These ?-1actamases were TEM-I (pI,5.4),SHV-12 (pI,8.2) and KPC-2 ( pI,6.7 ) confirmed by sequencing of the PCR products.Only one band of ?-1actamase with pI 6.7 was displayed in the transformant.A 1500 bp segment,which contained the KPC-2 gene confirmed by nucleotide sequence analysis,was cloned from a 60 000 bp plasmid of the transformant.Conclusion The strain of K.pneumoniae resistant to imipenem produces a plasmid-mediated carbapenemase KPC-2 which belongs to Bush group 2f,class A ?-1actamase.

ObjectiveTo detect the association between schizophrenia and polymorphism of phosphoserine aminotransferase 1 ( PSAT1 ) gene.MethodsThe study group included 158 patients with schizophrenia from Xi' an Mental Health Center and the control group included 316 parents.The polymorphism of rs69287125,rs137824326 of phosphoserine aminotransferase 1 gene was detected with PCR methods and SNP typing in all nucleus families by correlation analysis and haplotype relative risk analysis.ResultsThe rs69287125 allele was associated with schizophrenia (P=0.011 ),the G allele was protective factor (Z =-2.31 ) and the A allele was hazarding factor (Z =2.31 ).The rs137824326 allele was associated with schizophrenia (P=0.007 ),the G allele was protective factor ( Z =- 2.54) and the A allele was the hazarding factor( Z =2.54).The haplotypes of A/A and G/G in the rs69287125-rs137824326 were associated with schizophrenia (P =0.021,0.015,Z =2.16,- 1.85).ConclusionThe polymorphism of phosphoserine aminotransferase 1 gene is associated with schizophrenia in Chinese.

OBJECTIVETo observe the effects of Rubiae Radix et Rhizoma (RRR) and carbonized Rubiae Radix et Rhizoma (CRRR) on the acute blood stasis rat model, and reveal their differences in efficacy.

METHODThe acute blood stasis model was induced by subcutaneously injecting adrenaline hydrochloride and soaking in ice water. Yunnan Baiyao was used as the positive control drug, and administered for consecutively seven days. This model was adopted to observe the effect of high, middle and low dose RRR and CRRR groups on hemorheology, thrombin activity, and blood platelet system.

RESULTRRR could significantly reduce the wholeblood viscosity and plasma viscosity of blood stasis rats under different shear rates, and showed certain two-way regulating function in hemostasis. It also showed certain effect on ADP-induced platelet aggregation rate, but which was lower than CRRR. CRRR achieved the main hemostatic mechanism by stimulating intrinsic and extrinsic blood coagulation and fibrinogen, and could significantly enhance the platelet aggregation rate of rats in the acute blood stasis model (P <0. 01).

CONCLUSIONRRR had the effect of removing blood stasis and hemostasis, while CRRR mainly has the hemostatic effect. This further demonstrates the traditional processing theory of "promoting blood circulation with crude herbs and stopping bleeding with processed herbs".

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.
