ObjectiveTo explore the clinical effect of video-assisted thoracoscopic surgery(VATS) for chronic empyema. Methods74 patients with chronic empyema were divided into experimental group and control group,control group was given decorticationoflung,and experimental group was given VATS. ResultsThe duration of chest tube drainage, hospitalization and complications in experimental group was significantly better than that in control group,it showed better clinical effect. ConclusionFor part of patients without the serious disease change of chronic empyema, if the surgery indication could be controlled strictly, the VATS was considerable.

OBJECTIVE To analysis the effect of air disinfection by using nanometer light catalysis decontamination machine in operating room. METHODS By compare the effectiveness of air disinfection both by using nanometer light catalysis decontamination machine and ultraviolet rays light. RESULTS The result of tests is 0 CFU/m~2 by nanometer light catalysis decontamination machine and 33.3 CFU/m~2 by ultraviolet rays light in unmanned environment;By different groups: F=220.423,P=0.000,P

Objective To establish an effective PCR assay for leptospirosis detection , and applicate the assay in tree shrew, mongolian gerbil and gray hamster .Methods Sequence of leptospira was obtained from the NCBI Genbank , and primers were designed based on the sequences .The positive amplified fragments were sequenced to verify the reliability of the method.The samples from tree shrew, mongolian gerbils and hamsters were tested using this PCR method .Results The PCR method for detection of leptospirosis was successfully established .The positive rate of Leptospira was 8.33% in 60 samples of conventional tree shrews , 100% in 104 samples of the conventional Mongolian gerbils , and 0% in 60 samples of clean gray hamsters.Conclusions The establishment of this PCR assay is useful in the detection of leptospirosis in tree shrew, mongolian gerbil and gray hamster .The results of our investigation of leptospira infection levels of the three new experimental animals may promote their application in biomedical research .

OBJECTIVETo summarize application of rafting K-wires technique for tibial plateau fractures.

METHODSFrom January 2013 to January 2015,45 patients with tibial plateau fractures were treated by locking plate with rafting K-wires, including 33 males and 12 females with an average of 44.2 years old ranging from 22 to 56 years old. According to Schatzker classification, 6 cases were type II, 8 were type Ill, 4 were type IV, 4 were type V, and 5 were type VI. Allogeneic bone graft were performed for bone defects. All patients were fixed with two to five K-wires. Part of weight loading were encouraged at 3 months after operation,and full weight-loading were done at 5 months after operation. Postoperative complications were observed,and Rasmussen clinical and radiological assessment were used to evaluate clinical results.

RESULTSAll Patients were followed up from 10 to 23 months with average of 14 months. According to Rasmussen clinical and radiological assessment, clinical scores 23.58 ± 6.33, radiological scores were 14.00 ± 6.33; and excellent and good rates were 82.2% and 77.8% respectively. Four patients occurred severe osteoporosis and collapse of articular surface; 5 patients occurred traumatic arthritis.

CONCLUSIONRafting K-wires technique with anatomized armor plate could effective fix and support platform collapse and joint bone fragments, increase support surface area and reduce postoperative reduction loss rate.

Objective To study and summarize the tumor-free technique points for coordinating the operations aiming at rejecting aggressive spinal tumors by microwave and hyperthermia induced method. Methods 12 cases of patients with malignant bone tumors were performed with operations for rejecting tumor, using tumor-free technique to avoid cross infection, protect normal tissue nearby and prevent complications effectively. Results 12 cases of operations were successfully performed, no metastasis Was seen, no adjacent tissue injury and peri-operative complications occurod. Conclusions Microwave-induced hyperthermia in management of aggressive spinal bone tumors can increase the post-operative living-quality of patients, make both medical staff and patients satisfied and reach anticipated effect.

Objective To study the genomic molecular organization and genotype of human astro-virus infected infants in Shanghai of China. Methods Based on the published genomic sequence of HAstV (GenBank), the whole genome of one isolate human astrovirus was sequenced by specific primers. The PCR-products were cloned to pMD18-T vector and sequenced, phylogenetic tree was constructed by the Neighbor-Joining method with MEGA 4 software. Results The genome of HAstV-SH is 6807 hp, contains three ORFs: ORF1a and 1b encode the non-structural protein (from 83 nt to 4372 nt), ORF2 encodes the structural protein (from 4364 nt to 6727 nt). Compared with the ORF2 gene of those eight astrovirus sero-types in GenBank, revealed that the highest homology is with genotype 1 (97%). Homology with other gen-otypes ranged between 63% and 70%. Conclusion HAstV-SH belonged to genotype 1 and closely clus-tered with a strain of Japan (AB009985).
