It is significant to enhance the doctor-patient communication ability for medical graduates during clinical practice stage and establish appropriate doctor-patient communication sense,which is also important to promote medical education quality and cultivate qualified medical talents.This paper analyzed the common problems in doctor-patient communication for medical graduates.For example,patients did not trust the intern students;the students were nervous when faced with patients;some did not pay attention to their images;some called patients improperly.Then,it put forward some measures:to set up the communication and training courses,to carry out the communication skill training in clinical practice,and to attach importance to the doctor-patient communication skill practice.

OBJECTIVE To investigate the distribution and resistance of clinical isolates to antimicrobial agents commonly used.Antimicrobial agents should be used rationally based on the results of susceptibility testing.METHODS The clinical isolates were identified with W/A-40 or VITEK-32.The results were analyzed by WHONET 5.3 software according to CLSI 2005.RESULTS A total of 2892 clinical isolates were collected in 2007.Gram-negative bacilli accounted for 68.2% and Gram-positive cocci accounted for 31.8%.The top eight pathogens were Pseudomonas aeruginosa,Escherichia coli,Klebsiella spp,Acinetobacter spp,coagulase-negative Staphylococcus,Enterobacter spp,Serratia spp and S.aureus.About 76.4% of S.aureus isolates were MRSA,81.6% of coagulase-negative Staphylococcus isolates were meticillin-resistant.Under 20.0% of Enterobacteriaceae strains were resistant to cefoperazone/sulbactam,imipenem and piperacillin/tazobactam.About 16.3% and 32.5% of P.aeruginosa isolates were resistant to cefoperazone/sulbactam and imipenem.CONCLUSIONS Gram-negative bacilli were dominant isolates in our hospital during 2007.P.aeruginosa is the most frequent pathogenwith severe antibiotic resistance.Enterobacteriaceae are susceptible to cefoperazone/sulbactam and imipenem.

Objective To discuss the video-urodynamic characteristics and management in infra-sacral cord injured patients. Methods The video-urodynamic finding and managements in 169 patients was reviewed. They were followed up for 2 years. Results Detrusor areflexia was found in 76.33% (129/169) patients, among them there were 27.22% (46/169) patients appeared hyper-compliance, and 7.10% (12/169) patients appeared reflux. The video-urodynamic characteristics showed over activity and low-compliance in 12.43% (21/169) patients, including reflux in 5 cases. Different management was chosen according to the video-urodynamic examination. No special complication was observed after 2 years follow-up. Conclusion The majority patients with infra-sacral cord injury appeared detrusor areflexia and hyper-compliance. Special management according to the video-urodynamic characteristics is important for protecting upper urinary tract and preventing urinary system infection.

PcoI-PcoR is a quorum-sensing (QS) system influencing the biofilm formation and rhizosphere colonization in Pseudomonas fluorescens 2P24. The expression of the pcoI, a N-acyl-homoserne lactone (AHL) biosynthase gene, is under the regulation of a number of chromosomal factors, such as the GacS-GacA two-component system. In this paper, we investigated the upstream regulators that influence the transcription of pcoI gene using a chromosomal pcoI-lacZ fusion reporter strain PM203. Cosmids containing genomic DNA of the wild-type strain 2P24 were introduced into the reporter strain PM203 (gacA—, pcoI-lacZ) to screen positive transcriptional regulators of pcoI gene. One of them named pP32-24, which contained a 5-kb Pst I functional fragment was selected. Further analysis identified that the pcoI was the gene responsible for the increase of the pcoI-lacZ expression. The expression of pcoI-lacZ reporter was alsoimproved in both PM101 (pcoI-lacZ) and its gacAmutant PM203 after addition of exogenous AHL, indicating that the expression of pcoI is positively regulated by AHL (autoinduction) in strain 2P24. In addition, deletion mutagenesis and complementation experiments demonstrated that the transcriptional regulator PcoR positively controlled the expression of pcoI and the formation of biofilm. These results suggest that, in strain 2P24, the expression of PcoI-PcoR QS system is auto-inducted, and the transcriptional factor PcoR is involved in the regulation of pcoI transcription and the biofilm formation.

Objective To investigate the effects of PJ34,a poly ADP-ribose polymerase(PARP)inhibitor,on the expression of matrix metallopro-teinases-9( MMP-9 )and Claudin-5 in ischemic cortex of rats with focal cerebral ischemia-reperfusion(I/R)injury. Methods The focal cerebral ischemia-reperfusion model of middle cerebral artery occlusion(MCAO)was established by intraluminal suture . PJ34 was injected intraperitoneal-ly. Blood-brain barrier(BBB)permeability was quantitatively determined by Evans blue assay. Infarct volume changes were observed by 2,3,5-tri-phenyltetrazolium chloridedyeing(TTC)staining. The expression of the MMP-9 and Claudin-5 in rats of cerebral cortex were measured by immuno-histochemistry assay and western blot analysis . Results Compared with sham group,the expression of MMP-9,the contents of EB and infarct vol-ume increased progressively over time after I/R,and reached maximum levels at 48 h(P<0.05);The expression of Claudin-5,the contents of EB and infarct volume reduced significantly over time after I/R,and reached the minimum levels at 48 h in model group(P<0.05). Compared with model group,the expression of MMP-9,the contents of EB and infarct volume was reduced significantly and the expression of Claudin-5,the con-tents of EB and infarct volume was increased at the same time point in PJ34 group(P<0.05). Conclusion PJ34 maintained the blood-brain barri-er permeability by inhibiting the expression of MMP-9,and increasing the expression of Claudin-5,which had neuroprotection on cerebral ischemia-reperfusion injury.

Objective To investigate the effects of minimally invasive intracranial hematoma clearance on the perihematomal glutamate(Glu) level,permeability of blood-brain barrier(BBB) and brain edema.Methods Thirty rabbits with body weight of 2.80-3.40 kg were used to established the model of spontaneous intracerebral hemorrhage(ICH) and randomly divided into the minimally invasive group(MI) and control group(MC) after the model was prepared successfully.The MI group underwent minimally invasive procedures for removing intracranial hematoma by stereotactic instrument within 6 h after establishing the ICH model.The brain tissue was extracted on postoperative 1,3,7 d,and the perihematomal brain tissues were taken to detect the Glu level,BBB permeability and water content of brain tissue,which were compared with those in the control group.Results The Glu level,BBB permeability and brain water content on 1,3,7 d in the MI group were lower than those in the MC group,and the differences were statistically significant(P＜0.05).Conclusion The minimally invasive surgery for removing intracranial hematoma is helpful to reduce perihematoma Glu level,BBB permeability and brain water content.
