Case based teaching was applied in order to enhance the teaching efficacy and clinical safety for resident doctors in anesthesia training centers and to arouse their learning incentives and improve their clinical performance.Case based discussions on basic cardiopulmonary resuscitation and multiple traumas were conducted.Process consciousness was enhanced and theoretical knowledge analysis was combined with practical clinical skill training for residents in department of anesthesiology to improve the quality of training.

To investigate the location of Epstein-Barr virus (EBV) in renal tissues of patients with interstitial nephritis(IN). Methods By in situ hybridization. EBER1 was detected in renal tissues of 12 IN patients and 10 patients with minimal change nephropathy (MCN) as control group. Results EBER1 was found positive in 3 renal tissues of IN patients. It mainly distributed in the nuclei of renal tubular cells, infiltration cells and glomerular cells and 10 MCN patients were all negative. Conclusion EBV infection may play an important role in the pathogenesis of IN. In different types of IN, EBV infection may play different role.

The identification traumatic cataract must be based on the optical dysopia after ocular injuries. 72 cases of traumatic cataract were classified into 3 groups according to the classification of WHO about optical dysopia. There were 9 cases low vision, 58 cases blind and 5 incorporated cases after injuries. After operation, there were 12 cases that stenopeic spectacles vision was 0.4～1.2, 29 cases were low vision, 26 cases blind. The results suggested that the vision of traumatic cataract could be changed after operation, and the best time for forensic identification could be 1 or 2 months after operation.

Objective To observe the therapeutic effect and effects on coagulation indexes ofXuefu Zhuyu Capsules combined with chemotherapy in treating patients with mid-advanced small cell lung cancer (SCLC).Methods Totally 100 patients with mid-advanced SCLC were randomly divided into observation group and control group with 50 cases in each group. The observation group was given EP chemotherapy combined withXuefu Zhuyu Capsules, while the control group was given EP chemotherapy for 4 cycles. The coagulation indexes of two groups before and after treatment were observed, and the clinical efficacy and TCM syndrome efficacy were evaluated.Results After treatment, the tumor volume and TCM syndrome scores of two groups were lower than those before treatment (P<0.01), and the observation group was lower than the control group (P<0.01). The effective rate of the observation group was 100%, higher than 88% of the control group, the difference was statistically significant (P<0.05). The improvement rate of TCM syndrome score was 98% in the observation group, and was 84.0% in the control group. The observation group was superior to the control group (P<0.05). In observation group, D-dimer, platelet count and fibrinogen after treatment were lower than those before treatment (P<0.05,P<0.01), and were lower than those in control group (P<0.01). There was no significant difference of all kinds of adverse reactions between the two groups (P>0.05).Conclusion EP chemotherapy combined with Xuefu Zhuyu Capsules can improve hypercoagulable state in patients with SCLC, improve the effect of chemotherapy, and do not increase the adverse reactions.

Some documents had reported that plant-derived smoke water showed prominent effects of promoting seed germination, seedling growth and fruit quality of crops and horticultural plants. Recently, researches had also focused on the significant activity of smoke water in improving the yield and quality of medicinal plants, which provided new ideas for increasing the medicinal plants yield and quality. In this paper, physiological effects, active component, and mechanism of smoke water and its application in medicinal plants were summarized, which can be used as references of more value for the further development of medicinal plants.

Objective To construct the prokaryotic expression system of reteplase fusion protein and research the effect of chaperones on its renaturation. Methods Inserted the reteplase gene into the prokaryotie expression vector PET32a and then expressed it by the induction of IPTG in E. coli BL21. Researched the effect of chaperones on the renaturation of fusion protein by adding different chaperones. Results The analysis of SDS-PAGE and Western blot indicated that reteplase fusion protein was expressed correctly. Chaperones DsbA,pKJE7,pTf16 had the conspicu-ous effect on the renaturation of fusion protein. The result of activity assay indicated that the refolded reteplase fu-sion protein had fibrinolytic activity. Conclusion Chaperones can promote renaturation of reteplase fusion protein.

Objective To investigate the expression of poly (ADP-ribose) polymerase-1 (PARP-1 ), cytokeratins (CK) 7/20, and p53 in patients with Barrett's esophagus and esophageal adenocareinoma,and to evaluate their significance. Methods Expression of PARP-1, CK7/20 and p53 were determined by immunohistochemistry in 108 patients (including 40 Barrett's esophagus, 28 esophageal adenocarcinoma and 40 cardiac mucosa). Results The expression of PARP-1 was found in Barrett's esophagus, esophageal ade-nocarcinoma and cardiac epithelium with a significantly higher level in esophageal adenocarcinoma than the other two groups (P <0. 01 ). CK7/20 was expressed in much of intestinal metaplasia, part of cardiac epi-thelium and adenocarcinoma cells. The positive expression of p53 was observed in all three groups, and it was significantly higher in adenocarcinoma group than in other two groups (P < 0. 05 ). PARP-1 expression is highly correlated with that of p53 in Barrett's esophagus ( r= 0.49, P < 0.01 ). Conclusion CK7/20 is a sensitive but less specific indicator for intestinal metaplasia. Both PARP-1 and p53 are involved in the patho-genesis of esophageal adenocarcinoma and might help to determine the risk of Barrett's esophagus developing into esophageal adenocarcinoma.

Objective To detect the levels of tumor necrosis factor-α (TNF-α) and interleukin 10 (IL-10) in the plasma of patients with ulcerative colitis (UC); To investigate the clinical efficacy ofBaitouweng Decoction for UC and its influence on intestinal mucosal healing and partial mechanism.Methods Totally 66 patients with UC were randomly assigned to the treatment group and the control group. Patients in the treatment group were treated with Baitouweng Decoction (oral and enema treatment) and those in the control group took Mesalazine for 4 weeks. Before and after treatment, the therapeutic effects were assessed by Mayo scoring system and the grading of activities was evaluated by Baron Endoscope. Serum levels of TNF-α and IL-10 were detected by ELISA. Besides, another 20 healthy volunteers were recruited as the healthy control group for comparison.Results The endoscopic remission rate was 51.4% (19/35) in treatment group, higher than that of the control group (25.8%, 8/31,P<0.05). The clinical remission rate and efficacy rate in the treatment group were 74.2% and 88.6% respectively, higher than those of the control group (45.1% and 64.5%,P<0.05). The histological remission rate and efficacy rate in the treatment group were 25.7% and 54.3% respectively, higher than those of the control group (16.1% and 35.5%), without statistical significance (P>0.05). Serum levels of TNF-α were obviously positive correlated with Mayo score, Baron score and histology score (r=0.836, 0.735, 0.527,P<0.01). Serum levels of IL-10 were obviously negative correlated with Mayo score, Baron score and histology score (r=-0.704, -0.695, -0.509,P<0.01). Compared with pre-treatment, the serum levels of TNF-α significantly decreased (P<0.01), while the serum levels of IL-10 significantly increased (P<0.01) after treatment withBaitouweng Decoction.ConclusionBaitouweng Decoction (oral and enema treatment) is effective and safe in patients with UC. Its effects might be involved in regulating the imbalance of pro-inflammatory factors and anti-inflammatory factors, and promoting mucosal healing.
