Methods Sixty patients of chronic atrial fibrillation were divided randomly into treatment of Wenxin granules and amiodarone group (group A) and treatment of simple amiodarone gorup(group B),Thirty cases in each group. All cases were treated with amiodarone by intravenous drip along with oral amiodarone. Thirty cases in group A were treated with Wenxin granules (9 grams,per day) additionally for 4 weeks. Results Patients in group A resumed normal sinus rhythm significantly higher than that in group B. The increasing relapse tendency of atrial fibrillation was higher in group B within 6 months. Conclusion Drug combination with Wenxin granules and amiodarone has better effect than simple amiodarone in the relapse prevention of cardioversion of atrial fibrillation.

Objective To explore the clinical features of acute retroperitoneal colon perforation. Methods A retrospective analysis and summary were made on the clinical data of 20 cases of various retroperitoneal colon perforation. Results All of the 20 cases had been misdiagnosed preoperatively. Eighteen cases received surgical treatment, of which 5 cases underwent one-stage tumor resection, 5 cases had two-stage tumor resection and anastomosis;of 8 cases with traumatic perforation,7 were treated by simple suture, 1 case underwent two-stage colonic anastomosis; 2 cases died,all the 2 cases were treated conservatively.Conclusions There are many differences between retroperitoneal colon perforation and intra-abdominal perforation in clinical symptoms, signs and supplementary examinations. Diagnosis of retroperitoneal colon perforation is difficult and the rate of misdiagnosis is high, so this condition must be highly regarded.Surgery is the best option to treat this disease.

Objective To study the flow fields of electrolysis oxygen generation with micro-flow-channels of small square cylinders and the key structure factors impacting on the uniform distribution of the water flow in the micro-flow-channels.Methods The low Renault k-? model was used to represent the characteristics of the flow field in the micro-flow-channels.And the simulation results of the flow fields by CFD were calibrated by comparing with that of the particle image velocimetry(PIV) experiments,which showed that the low Renault k-? model was suitable to describe the flow field of the micro-flow-channels.Results The flow fields of variable flow were obtained.Conclusion The flow fields of variable flow rates distribute non-uniformly.The velocity magnitude is 10-3m/s,and the inlet structure of the electrolysis oxygen generation is a key factor impacting on the uniform distribution of the water flow.

BACKGROUND: Bone marrow mesenchymal stem cells are prospective used in cartilage tissue engineering due to easy acquire and plentiful amplification in vitro in a short term.OBJECTIVE: To summarize the application of bone marrow mesenchymal stem cells in repairing cartilage defect.RETRIEVAL STRATEGY: A computer-based online search was conducted in Pubmed for English language publications containing the key words of "marrow; mesenchymal stem cells; cartilage defect" from October 1982 to December 2006, Relevant data were also searched in China Scientific and Technological Achievement Database for Chinese language publications containing the key words of "marrow; mesenchymai stem cells; cartilage defect" from October 1982 to December 2006. There were 126Exclusion criteria: duplicated articles.LITERATURE EVALUATION: Literatures including reviews and experimental studies were mainly derived from Pubmed database and China Scientific and Technological Achievement Database.DATA SYNTHESIS: It has been proved that bone marrow mesenchymal stem cells could differentiate into cartilage in vivo.However, differentiation of cartilage phenotype in vitro was restricted by multiple factors, and the controlling mechanism is still unclear up to now. Animal experiments demonstrated that bone marrow mesenchymal stem cells could repair bone and cartilage defect. Although studies on bone marrow mesenchymal stem cells and cartilage tissue engineering have developed to a certain degree, clinical applications and evaluations, including cell marks of bone marrow mesenchymal stem cells in different differentiated stages, controls of proliferation and differentiation of bone marrow mesenchymal stem cells, and gene transfection technique, still need a further study.CONCLUSION: Animal experiments indicate that bone marrow mesenchymal stem cells can significantly repair bone and cartilage defect. Although studies on bone marrow mesenchymal stem cells and cartilage tissue engineering have developed to a certain degree, problems of bone marrow mesenchymal stem cells in basic and clinical researches still need to be solved further.

Objective: To investigate the characteristics of traditional Chinese medicine (TCM) syndromes and their elements in patients with posthepatitic cirrhosis by analyzing the relationships between signs and symptoms and biochemical parameters. Methods: A total of 440 patients with hepatitis B cirrhosis treated in Shanghai Public Health Center and Shuguang Hospital, Longhua Hospital and Central Hospital of Putuo District Affiliated to Shanghai University of Traditional Chinese Medicine during January 2002 to January 2006 were enrolled in this study. Signs and symptoms and biochemical information of patients were collected by using a self-designed questionnaire regarding the four examinations of TCM. Signs and symptoms were firstly analyzed to find the frequency of occurrence. Then, the patients were divided into two groups according to non-existent or existent sign and symptom and the correlations between the signs and symptoms which occurred most frequently and their biochemical parameters were analyzed. Results: Sixteen symptoms which occurred most frequently were fatigue, colored urine, liver palms, opaque complexion, string-like pulse, weakness at waist and knees, dry month and bitter taste in the mouth, profuse dreaminess and poor sleepiness, heaviness of limbs, abdominal distention, yellow eyes, fine pulse, impetuosity and susceptibility to rage, splenomegaly, poor appetite, and distension and fullness in the chest and hypochondrium. A previous study on syndrome differentiation of 900 patients with posthepatitic cirrhosis showed 4 syndrome patterns: internal accumulation of dampness-heat, liver-kidney yin deficiency, internal accumulation of blood stasis-heat, and liver depression and spleen deficiency. Further analysis showed that internal accumulation of dampness-heat syndrome was characterized by obvious hepatic inflammation, poor synthesis function and more asctites. Liver-kidney yin deficiency syndrome was characterized by low-level hepatic inflammation, poor synthesis function and more ascites. Internal accumulation of blood stasis-heat syndrome was characterized by low-level hepatic inflammation, poorer synthesis function, ascites and splenomegalia, and liver depression and spleen deficiency syndrome was characterized by slight hepatic inflammation, synthesis function injury, decreased internal portal vein diameter and less ascites. Conclusion: Different syndrome patterns have different pathological features, showing the complexity and polymorphism of syndrome construction.

In recent years, with the development of sequencing technology and research on molecular changes in different races of prostate cancer, it has been found that the pathogenesis of prostate cancer showed obvious ethnic differences. This article reviewed the research progress of ETS fusion genes, FOXA1, SPOP, IDH1 and other driver genes in prostate cancer. And the research of molecular typing of prostate cancer showed different patterns of molecular changes in Chinese and western populations. The molecular changes of prostate cancer in western populations were dominated by ETS fusion gene, while those in Chinese populations were dominated by gene mutations, mainly FOXA1 and SPOP mutations. Moreover, the dominant fusion gene in Chinese prostate cancer was not ETS fusion gene, but SCHLAP1-UBE2E3.

OBJECTIVE To evaluate the difference of efficacy of sublingual immunotherapy on different age patients with allergic rhinitis. METHODS 229 patients with dermatophagoides farina drops allergic rhinitis who have finished SLIT at least 2 years were enrolled and analyzed by retrospective analysis. All patients were divided into different age groups: pre-adolescence(n=107), adolescence(n=53), adulthood(n=69). Indexes for therapeutic effects of SLIT visual analogue scale(VAS) score, rhinitis symptom scores, medication scoreintra- and inter groups were assessed during different stage of treatment(3 months, 1 year and 2 years). Data were analyzed with SPSS 19.0 software. RESULTS Compared with prior treatment, after the SLIT for 3 months, 1 year, 2 years, VAS scores, rhinitis symptom scores, medication scoresof all the patients with allergic rhinitis are significantly decreased; Differences of rhinitis symptom scores(H=0.844, 4.153, 2.669, P>0.05), VAS score(H=1.356, 3.720, 0.313, P >0.05), medication scores(H=1.044, 5.841, 3.399, P>0.05) between groups had no statistical significance at different stage after treatment(3 months, 1 year and 2 years); The differences between 2 years and 1 year of SLIT treatment showed statistical significance in the VAS scores(Z=1.635, P =1.635). CONCLUSION SLIT with dust mites drops had good curative effect and security in patients with allergic rhinitis, which hadno obvious difference between different age groups.
