OBJECTIVE To investigate the usage of antibiotics in surgical department of Chest surgery in PLA General Hospital.METHODS The antibiotics usage status among 412 cases of patients during perioperative period was retrospectively analyzed.RESULTS The utilization of antibacterials took up to 100.00%.The average of treatment course was13.89 days,Aminoglycosides,cephalosporin and penicillins was the main kinds,single use accounted for 28.64%,the bigeminy for 35.93%,and trigeminy for 30.58%,the utilization with four or more kinds of drugs were 4.85%.The rational usage and irrational usage accounted for 64.57% and 35.43% respectively.CONCLUSIONS Clinicians should strengthen the management of antibiotics in perioperative period for rational use.

Whole brain radiation therapy has become the standard treatment of non-small cell lung cancer (NSCLC) with brain metastasis,because it prolongs the survival times of NSCLC patients with brain metastases.The emergence of molecular targeted drugs is a major innovation in the traditional sense of the cancer treatment.Molecular targeted drugs have many advantages such as convenient dosing,rapid onset,improving the intracranial and extracranial tumor lesions at the same time,mild adverse reactions and good tolerance,which provide a new and better choice for the treatment of NSCLC patients with brain metastases.

A statistical analysis was conducted to evaluate the publication status in medical research of Shandong province in 2013, based on papers covered in SCI-Expanded database, aimed to provide an objective assessment of the level of medical research in Shandong Province.Factors involved in the analysis including medical papers authored by researchers in Shandong province, numbers and types of publication, distribution of author's location, institution, type of periodical, and impact factor.

Objective To investigate the influence of comprehensive psychological intervention and cognitive therapy on cognitive function in schizophrenia.Methods A total of 80 patients with schizophrenia were randomly divided into the comprehensive psychological intervention group (group A,n=40)and the cognitive therapy group (group B,n=40).Before and after 8-week treatment,the influence on cognitive function were measured with WAIS-RC,WMS,WCST and TESS were compared between two groups.Results After eight weeks,the intelligence quotient,remembrance quotient ,sustained errors and random errors in group A (110.52±18.03,110.78±1.15.42,15.48±9.82,17.46±13.28) were higher than that in group B (96.64±18.26,102.23±13.4,20.35±11.47,24.92±13.71).The difference between the two groups was found in improving cognitive function in schizophrenia patients(P＜0.05).Conclusion Cognitive therapy could improve cognitive function in schizophrenia,but comprehensive psychological intervention would do much better.

Objective To study the characteristics of mutations of gene COL4A5 encoding type Ⅳ collagen ? 5 chain in one chinese pedigree with X-linked dominant inherited nephritis (Alport's syndrome,AS). Methods Genomic DNA was extracted from 35 members of the pedigree of Alport's syndrome. All of 51 exons of COL4A5 gene were amplified by PCR with the primers synthesized according to the published intron sequences of COL4A5. The PCR products were further analyzed by agarose gel electrophoresis and single strand conformation polymorphism (SSCP). The PCR products showing polymorphism were directly sequenced. Results PCR-SSCP analysis showed that 17 PCR products had abnormal mobility of single strand DNA. DNA sequencing analysis revealed 9 suspicious mutations. But these suspicious mutations were not be confirmed by inverse sequencing analysis. Conclusion The exon mutation of COL4A5 gene of this pedigree did not be found, and the mutations of COL4A5 gene may locate in the its introns.

[Objective]To observe the effect of the nonunion of humeral shaft fracture treated by bidentate intramedullary locking nails.[Method]Twenty-five cases of fracture nonunion of humeral shaft were cured by bidentate intramedullary locking nails from January 2000 to November 2004.and they received operations to remove their previous instruments.After the bidentate intramedullary nails was inserted via antegrade approach,and autogenous cancellous bone was grafted.[Result]Twenty of the 25 cases were available for follow up.The follow up lasted 10 to 26 months.All cases achieved solid union within 4 to 10 months.There were no complication such as incision infection or occurring of osteomyelitis.[Conclusion]Bidentate intramedullary locking nails can provide the effective control of harmful shearstress,it can provide firm internal fixation,And this methods is an ideal method for treatment of humeral shaft fracture nonunion.

Objective To investigate the correlation between the expression of vascular endothelial growth factor-C(VEGF-C) and lymph node metastasis in gastric cancer. Methods The expression of VEGF-C was detected in 30 pairs of fresh primary gastric cancers and their adjacent normal tissues from the same patients by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. Automated image analyzer was used to quantify VEGF-C expression, which was reflected by positive index (PI). Results VEGF-C was highly expressed in gastric cancer cells,whilst its expression was undetectable in adjacent normal tissues. VEGF-C expression was higher in lymph node metastasis group(PI=1.345?0.079) and lymphatic invasive(PI=1.315?0.037) group than that in no-metastasis group(PI=1.156?0.045) and no-invasive group (PI=1.154?0.043)(P

The principles of balance, randomization, control and repetition, which are closely related, constitute the four principles of scientific research. The balance principle is the kernel of the four principles which runs through the other three. However, in scientific research, the balance principle is always overlooked. If the balance principle is not well performed, the research conclusion is easy to be denied, which may lead to the failure of the whole research. Therefore, it is essential to have a good command of the balance principle in scientific research. This article stresses the definition and function of the balance principle, the strategies and detailed measures to improve balance in scientific research, and the analysis of the common mistakes involving the use of the balance principle in scientific research.

ObjectiveTo valuate the clinical effect of maintence of arteriovenous fistula by Songling Xuemaikang capsule.Methods40 cases were obtained from patients with chronic renal failure had received arterio-venous fistula operation,24 cases were observed with the combination treatment and 16 cases were served as control group,Hemorheology and difference value of vein diameter before and after treatment,blood flow of native arteivenous fistula and primary using time were observed.ResultsThe improvement degree of high shear rate and low shear rate were significantly as compared with that in the control group (P =0.000,P =0.001 ),while the blood flow after fistula maturation and ifference value of vein diameter were better than that in the control group( P =0.0356),primary using time between two groups were no significant differences ( P =0.056).ConclusionSonglinxuemaikang capsule was an effective drug for prevention high blood caogulation state,increasing blood flow of native arteivenous fistula,and enlargment vein diameter after arterio-venous fistula operation,which had certain value in clinical application.
