Objective To explore the pathogenesis and clinical value of Th1/Th2 and normal intestinal flora from the angle of immunological and intestinal micro environment balance by detecting the plasma interferon-γ(IFN-γ)and interleukin-4(IL-4)and fecal bifidobacteria in Children with Allergic Asthma,so as to provide a theoretical basis through early intervention of probiotics to correct the Th1/Th2 balance.Methods The levels of blood plasma IFN-γ,IL-4 and fecal bifidobacteria amount of 165 cases of chil-dren with allergic asthma and 150 health students as control group were detected by ELISA and real time fluorescence PCR at the same time.Retesting these above indexes after applying bifidobacteria regulation of intestinal flora for 6 months.The clinical relative factors and experimental data were statistically analyzed.Results The level of IFN-γof asthmatic children were remarkably lower than those in the control group(P <0.05),while the level of IL-4 of asthmatic children were remarkably higher than those in the control group(P <0.05),and the amount of bifidobacteria of asthmatic children were remarkably lower than those in the control group(P <0.05).The level of IFN-γand bifidobacteria of asthmatic children improved remarkably and the level of IL-4 decreased significantly after applying bifidobacteria regulation of intestinal flora for 6 months.All of them had remarkable statistically signifi-cant.Conclusion The immune balance was affected by the intestinal flora balance of vice versa.This would provide an important theo-retical support to prevent the occurrence of allergic asthma by the early probiotics regulation of intestinal flora and immune balance.

Objective: To evaluate the clinical effect of the double-orifice technique in the treatment of the anterior leaflet prolapse of mitral valve. Methods: 35 patients with severe anterior leaflet prolapse of mitral valve underwent valve repair using the double-orifice technique. The condition of valve was assessed with echocardiography preoperatively, intraoperatively, and postoperatively. Results: The mean postoperative valve area was (4 1?1 8) cm 2 against the preoperative valve area of (8 3?1 6)cm 2. Mild regurgitation was found in 2 patients after operation. There were no hospital deaths. At the latest follow-up, the heart function was improved significantly in all patients (NYHA class I). Echo-Doppler assessment of valve showed stable valve function in all patients. There were no late stenosis of valve and no late death. Conclusion: The results of this study show that the double-orifice technique is a safe and effective method for treatment of anterior leaflet of mitral valve with low mortality and morbidity, and excellent early and mid-term results.

Therapies for uveitis include drug treatment and surgery.Medical therapies including proper administration of corticos- teroids,immunosuppressive drugs,nonsteroidal anti-inflammtion drugs and anti-infective drugs are important in management of the in- traocular inflammation and decreasing the risk of complications,furthermore,are the basis for surgical treatment of uveitis.

The learning passion,apprehension and master of probation knowledge and practice capacity of probationers have improved greatly by applying the teaching method of stage-separated to echelon teaching on the basis of the cognitive law and focusing on clinical operation practice.Meanwhile,this method has effectively improved clinical probation teaching quality of orthopedics.

Objective: To analyze the construct validity of performance evaluation system of clinical centers by exploratory factor analysis strategy, so as to provide evidence for optimizing the parameters of the evaluation system. Methods: Using the exploratory factor analysis method, we evaluated the construct validity of the constructed performance index system. Results: Factor analysis showed that the factor components (listed in an increasing importance order) were: discipline superiority, cultivation of talented persons, medical service, scientific research capability, and infrastructure construction, etc. (the cumulative contribution of the first 6 factors was 90.17%). Most of index factor loadings matched with the meaning of their corresponding factors, indicating that the construct validity of the evaluation system was consistent with the expectation of its designers. Conclusion: The constructed clinical center performance evaluation system has a reasonable factor structure.

Objective To investigate the relationship between subclinical cervical HPV infection and recurrence of condyloma acuminatum (CA) in patients. Methods Cervical swabs were collected from 52 patients with frequently recurrent CA, 55 patients with infrequently recurrent CA, and 65 normal human controls. The Cenechip method was performed to detect the presence and type of HPV in cervical swabs followed by a statistical analysis. Results HPV was found in 67.3% (35/52) of swabs from patients with frequently recurrent CA, 5% (19/55) from patients with infrequently recurrent CA, and 4.6% (3/65) in the controls. There was a statistical difference among the three groups in the detection rate of HPV. Conclusion The subclinical cervical HPV infection may contribute to the recurrence of CA.

Objective To investigate the changes of myocardial combination enzyme in the early stages of gunshot wound of dogs in seawater for exploring early treatment protocol. Methods Fourteen conventional Beagles models undergoing gunshot wound in seawater were used along with another 3 dogs receiving the wound on land to serve as control. After the dogs were rescued from the seawater, the origin of blood coming from central venous pressure tube was measured (33.75?25.29) min before and after injured for indexes such as alkaline aminotransferase (ALT) , aspartate aminotransferase (AST) , creatine kinase (CK) , creatine kinase isoenzymes - MB (CK -MB) , lactate dehydrogenase (LDH) and adenosine monophosphate (AMY) in the early stages of wound, followed by statistical analysis of the results. Results There was an increase in blood CK (P0.05). As compared with the control, the experimental group in seawater was observed to have significant difference in blood AMY (P 0.05). But it was noted that CK, CK - MB , LDH , AST and ALT contents tended to increase. Conclusion The functions of respiratory, heart, liver and kidney were injured and restrained in Beagle dogs undergoing the firearms wound in natural seawater. The immediate diagnosis and treatment of the organism as well as the out - of - wound - tract injury shoud do while the firearms primal wound tract were treated in the early stages of gunshot wound.

Aim To apply simple combined models to screen small molecule BDNF-like compounds for potential pharmacotherapy of central nerve degenerative diseases.Methods BDNF-like bioactivities were dentified with effects against apoptosis induced by serum withdrawal in turn in cultured human SH-SY5y cells,rat NIH3T3/trkB cells vs NIH3T3 cells,using MTT technique.Results More than 400 compounds were tested by using these methods.11 of them presented protective effects on apoptosis induced by serum withdrawal in SH-SY5y cells.2 of them also provided selective protection against apoptosis induced in NIH3T3/trkB cells versus in NIH3T3 cells,which were identified as BDNF-like compounds.Further study showed that these 2 compounds could withstand SH-SY5y cell injuries induced by 6-OHDA.Conclusion All the above studies provide a useful series of simple models for BDNF-like drug screen and some compound candidates for further study of neuroprotection.

Objects: To measure practicing medical students' basal energy expenditure(BEE). Methods: 200 practising medical students were chosen to measure BEE by standard method of CCM metabolism cart,and the BEE results were compared with forecast values from the calculation formula of healthy adult. Results: Actual BEE of male students was(4 920.4?1 343.1)kJ/d,female(3 393.2?824.2)kJ/d.The results were significantly lower than corresponding forecast values.Conclusion: The BEE of practising medical students is lower than forecast values from the calculation formula of healthy adult,showing that students' constitution was poorer.The possible reasons may be less exercise and diet.
