In order to perfect the course-setting and enhance the teaching effect,we questioned our students' knowledge about the position and quality of medical law and the style of teaching, examining method etc. It proves that there are some differences between the fact and students'expectation on these questions.Furthermore, the author put forward some concrete advice on them in this article.

Coincidence exists in the value selection,main form of human communication and imbalance between teacher-student relationship and doctor-patient relationship.Therefore,teacher-student relationship today will directhy have an impact on the future of doctor-patient relationship.Teachers should cultivate medical students'equality consciousness and communicating ability between doctors and patients by establishing equal relationship and good communication between teachers and stdents.

As a patient's right,informed consent has been acknowledged universally.Both hospital and patients attach great importance to normal informed consent during clinic.But the subjects' right in clinical trial didn't draw enough attention,which leads to encroachment of the subjects' right and even the clinical disputes.The law and rule,based on the ethics principle,can enhance the protection of the subject's right of informed consent.In this article,the problem on the legal protection against the infringement of the subject's right and the corresponding counter-measures are discussed.

Objective To evaluate the influence of Motivational Interview on function restore and life quality after artificial unilateral total hip replacement surgery. Methods A convenient sampling method was used for collecting 103 patients underwent artificial unilateral total hip replacement surgery for the study. Lottery method was used to divide these patients in to treatment group 53 cases and control group 50 cases. Intervention of both joint exercise and motivational interview was used for the treatment group, and routine health education was used for the control group in a large general hospital in Hangzhou. Results 1 month later, patients′joint function assessed with Harris score of the intervention group and control group were 62.40 ± 8.95 and 54.06 ± 9.61; 3 months later, intervention group was 82.25 ± 7.09 while control group was 74.60 ± 9.97, the difference was statistically significant (t=-4.559 and-4.451, P=0.000). Patients′life quality after 1 month was 485.54 ± 86.85 in intervention group and 400.69 ± 72.36 in control group;3 months later, the scores were 601.54 ± 73.49 and 543.08 ± 81.77, the difference was statistically significant (t=-5.370 and-3.821, P=0.000). Conclusions Motivational Interview was capable of improving joint function restore and quality of life through changing patients′ motivation, helping patients establishing and adhering to joint exercise.

OBJECTIVE To investigate the nosocomial status and drug resistance of imipenem-resistant Pseudomonas aeruginosa(IRPA) to provide the reference for doctor′s use of the antibiotics.METHODS Totally 178 strains of imipenem-resistant P.aeruginosa were identified by the routine methods.And drug sensitivity was determined by Kirby-Bauer method.RESULTS All strains of IRPA were mainly from departments of respiratory diseases,tumor and geriatrics,most of them were isolated from sputum(62.4%).The susceptibility test showed that 100.0% IRPA were resistant to imipenem.Drug resistance rates to piperacillin,cefotaxim,gentamicin,ciprofloxacin and SMZ-TMP were all over 50.0%.CONCLUSIONS The status of nosocomial infection caused by IRPA is very serious.To detect and control the infection is very important.

OBJECTIVE To study the state of mixed infection of sexually transmitted diseases(STDs) pathogens isolated from female genitourinary tract and analyze the clinical meaning.METHODS Gram staining and test under microscope,DIGFA,cultivation and enzyme linked immunosorbent assay were adoptmaed to detect five pathogens such as Neisseria gonorrhoeae,Chlamydia trachomatis,Ureaplasma urealyticum,Mycoplas hominis and herpes simplex virus.RESULTS Among 2 188 female patients,we got 175 mixed infection cases,accounted for 8.0%.77.7% Patients were 21 to 40 years.CONCLUSIONS We should pay attention to monitoring STDs and control work.

Medical Ethics Committee founded in medical orgnizations,universities,academic periodicals and hygiene institutes is an international regulation in the filed of medicine.Although we have done a large amount of work to be in line with international standards,there are still some problems such as no systemic roles,function deficiencies etc.Therefore,we should study its establishing background and main function and strengthen its construction.

Objective To explore the association between the signal transducer and activator of transcription 4 (STAT4) gene polymorphism and Chinese Han systemic lupus erythematosus patients. Methods Pyrosequencing technique was used to genotype the 3 single nucleotide polymorphisms (SNP) in the samples of patients and normal individuals. Results Not only these 3 SNPs, but also the haplotypes composed by them showed significant difference between the SLE patients and normal individuals[rs11889341:P=0.012 02, OR (95%CI)=1.22( 1.044～1.424); rs7574865:P=0.003 454, 0R(95%CI)=1.25(1.076～1.451 ); rs8179673: P=0.004 275, OR (95%CI)=1.274 (1.079～1.505)]. Conclusion rs11889341, rs7574865 and rs8179673 of STAT4 are associated with the pathogenesis of Chinese Han SLE, and the STAT4 gene is a susceptibile gene for SLE in a few racial cohorts.

OBJECTIVE To establish a simple,sensitive method for detecting the double mutation of the basal core promoter(BCP) of HBV.METHODS FAM fluorescence-labeled TaqMan MGB and primers driving from the region containing the double mutation of BCP were designed for the real time PCR,then the standard positive control,standard negative control and HBV DNA were amplified and detected by the real time PCR.The results of detecting the double mutation of BCP were validated by the direct-sequencing analysis of PCR products.RESULTS The double mutation of BCP of HBV could be detected by the real time PCR.The sensitivity of the method was 3?100 copy templates and as few as 1% of mutant among wild-type virus sequence were detected.CONCLUSIONS The method can be used to detect the double mutation of BCP of serum HBV DNA.

OBJECTIVE To approach the pathogenic distribution of nosocomial infection and drug-resistance in tumor department to formulate the intervention strategy.METHODS Prospective monitoring and retrospective investigation were performed to analyze the 198 cases of nosocomial infection in tumor department.RESULTS The lower respiratory tract infection was the main infection in tumor department,accounted for 68.2%.The urinary tract infection rated the second,accounted for 16.7%.Pathogenic bacteria mainly included Pseudomonas aeruginosa(20.2%),Klebsiella pneumoniae(19.2%),Escherichia coli(16.2%),Staphylococcus aureus(10.6%),etc.Above pathogenic bacteria were all multidrug-resistant.Detection rate of extended spectrum ?-lactamases(ESBLs) producing Enterobacteriaceae strains was 45.7%.Detection rate of meticillin-resistant staphylococci(MRS) was 40.6%.CONCLUSIONS The drug-resistance status of nosocomial infection is very serious in tumor department.Comprehensive intervention strategy should be adopted to decrease the infection rate.
