BACKGROUND:Spinal cord injury can cause the motor, sensory and autonomic dysfunction below the damaged surface, so the repair of spinal cord injury has been the problem of neuroscience research. OBJECTIVE:To analyze the mechanism, experimental research and clinical application of olfactory ensheathing cel transplantation for the repair of spinal cord injury, and to investigate the effect of olfactory ensheathing cel transplantation on neurological function recovery. METHODS:The basic experimental and clinical researches on olfactory ensheathing cel transplantation for the repair of spinal cord injury were retrospectively analyzed, in order to analyze the relationship between the number and time of the survival cells and the structure and function of the damages spinal cord after olfactory ensheathing cel transplantation. The inclusion and exclusion criteria of the included clinical researches, and the sources, types and transplantation method of the cells used for transplantation were clearly defined, then the effective and objective evaluation criteria was established. RESUTLS AND CONCLUSION:The animal experiments of olfactory ensheathing cel transplantation for the repair of spinal cord injury have achieved satisfactory effects. The spinal cord function score and the sensory and motor function were significantly improved compared with those before transplantation (P<0.001). The successful animal experiment could provide basis for the clinical experiment and application. Parts of the clinical experiments were fol owed-up for 5 years. Because of a smal amount of the cases in the clinical research and the short fol ow-up period, the final recovery of large number of cases cannot judged yet, further observation and research were required. The great significance of the research result is to help to find a reasonable strategy that can make the olfactory ensheathing cells displayed repairing effect sufficiently.

Critical Discourse Analysis ( CDA) attempts to uncover the inequality in social reality and the way language presents power and ideology through the analysis of language features. Systemic functional linguistics ( SFL) focuses on the dialectical relationship between language and society and has been considered an important approach and theoretical basis to CDA. Doctors in Chinese medical clinic follow the Four Diagnostic Methods, within which the inquiry diagnosis strongly shows the fact that doctor and patient clash over the ideology and strug-gle for the power via language. The study carries out CDA on doctor-patient discourse in Chinese medical clinic within the theoretical framework of SFL from four aspects including nominalization, classification, transitivity and mood, which verifies that the language is the product of asymmetric power between doctor and patient. It is hoped that the paper would provide insight into CDA on doctor-patient discourse and would be of theoretical meaning.

Objective To detect the expression of protein kinase C(PKC) in multidrug resistant cells of colorectal carcinoma after ionizing irradiation and observe the effect of PKC on occurrence and development of the multidrug resistant.Methods The effect of PKC on multidrug resistant HCG-8 cells of colorectal carcinoma after treated with X-ray was detected by indirect immunofluorescence technique and flow cytometry.Results Compared with sham-irradiation group,the positive percentage of PKC was increased significantly(P

0.05).The percentage of eosinophils in induced sputum in asthmatics(16.3?7.2)% was higher than those in healthy volunteers(0.7?0.6)% and in COPD(6.5?5.4)%(P

OBJECTIVE To characterize the pathogenic distribution and drug resistance of nosocomial infection occurred in tumor hospital and therefore provide the information in rational administration of antibiotics to tumor patients complicated with infection.METHODS Flora cultivation and isolation were operated with the methods described by the National Clinical Laboratory Operational Regulations.Flora was identified with the VITEK-32 automatic identifier,and bacteria-susceptibility test was operated with Kirby-Bauer method.RESULTS Totally 1280 strains of pathogenic bacteria were isolated;they comprised 874 strains of G-bacteria and 416 strains of G+ bacteria.In this study,the isolation rates of Pseudomonas aeruginosa,Escherichia coli,Acinetobacter,Enterobacteriaceae and Klebsiella were 14.92%,14.92%,14.06%,13.91% and 10.47%,respectively;whereas that of Streptococcus Group D and Staphylococcus aureus were 24.06% and 7.70%,respectively.Both E.coli and S.aureus were much resistant to antimicrobial agents tested;while imipenem and vancomycin might be chosen for the G-and G+bacteria infection.CONCLUSIONS The bacterial spectrum and their drug-resistance characteristics in the tumor hospital are quite similar to that encountered in general hospitals.So the information on nosocomial infection control from the latter is of great importance in directing on and carrying out the same job in tumor hospital.

Aspirin-induced asthma(AIA)is a distinct clinical syndrome characterized by adverse respiratory reactions to aspirin and other nonsteroidal anti-inflammatory drugs(NSDIDs).AIA is refractory asthma.To better understand the disease of AIA,this article reviews the epidemiology,clinical feature,the methods of diagnosis and the treatment of AIA.

Objective To investigate feasibility, efficacy and safety of holmium laser lithotripsy under ureteroscopy to treat ureteral calculi. Methods Clinical data of 162 patients with ureteral calculi treated by holmium laser lithotripsy under ureteroscopy in our hospital from June 2006 to October 2009 were reviewed retrospectively. Stone-broken rate,lithagogue rate and complication were observed. Results The overall rate of successful fragmentation for all levels of ureteral calculi in a single procedure achieved 96. 30% (156/162). The success rates of fragmentation for the upper and mid-lower segment of ureteral calculi was 86.11% (31/36)and 99.21% (125/126),respectively. In 156 patients, the postoperative follow-up of 2- 4 weeks revealed that the stone free rate was 98.08 % (153/156). The mean operative time was (36 ± 11 )mains ( ranged from 15 to 90) and hospital stay ranged from 1 to 10 days. Conclusion Holmium laser lithotripsy under ureteroscopy is feasible,high effective and safe for the treatment of ureteral calculi, especially for those with middle or lower levels ureteral calculi.

Objectives To establish the mouse heart transplantation model and observe the effect of anti-rejection of IL-12 antibody.Methods Twenty-five mice undergoing heterotopic heart graft were divided into 4 groups:isograft one(n=5),simple homograft one(n=6),γ-globulin treated one(n=6)and IL-12 antibody treated one(n=8).Results The survival time of cardiac graft in the groups was as follows:＞ 100 days in isograft group,7.3 days in simple homograft group,7.5 days in r-globulin treated group and 15.4 days in IL-12 antibody treated group.Conclusions A stable mouse heart transplantation modd was established.IL-12 antibody could significantly prolong the survival of mouse cardiac graft and antagonize rejection of organ transplantation.

Thrombospondin-1 is known as its anti-angjogenic and proapoptotic activities in oncogenesis. In current research, it has a intimate relationship with taxol resistance. Sensitivity of tumor cells to taxol will descend when the expression:of TSP1 is downregulated,and TSP1 downregulation is mediated by a new gene of taxol-resistance gene 1, the discovery provids a new trend to solve taxol resistance.

Objective To analyze the clinical effect of intracranial hematoma by drilling skull in treatment with hypertensive brain hemorrhage.Methods 188 patients with hypertensive cerebral hemorrhage were classified into control group with 94 cases and traditional group with 94 cases.The control group were treated with conservative medicine and observation group were treated with intracranial hematoma by drilling skull.The clinical efficacy and defection score of nerves function were observed and compared between the two groups.Results The total effective rate in observation group was significantly higher than that in control group(P＜0.05) while the death rate in observation group was significantly lower than that in control group (P＜0.05),Compared with pre-treatment,after treatment 2 weeks and 4 weeks,the Barthel index in two groups were significantly increased(P＜0.05).Moreover,after treatment 2 weeks and 4 weeks,the Barthel index in observation group was significantly higher than that in control group(P＜0.05).Conclusion The intracranial hematoma by drilling skull can enhance effective rate,decrease death rate and improve the ADL ability.
