Objective:To evaluate the prognosis of acute peripheral arterial embolization.Methods:From Jan 1990 to Jun 2002,117 cases with 149 times of embolization were analyzed retrospectively to determine the distribution,amputation rate and mortality of arterial embolization.Logistic regression was employed to define the role of site,the extent and range of ischemia,ischemic time,treatment modality,with or without atherosclerosis,and recurrent onset on amputation rate of extremities.Results:Approximately 87% of embolization occurred in lower limbs,that occuring in internal organ was about 2% and upper extremities 10%.Among 117 cases,the mortality was 11.9%,amputation rate 7.8% and limb salvage 92.2%.Conclusion:Underlying heart disease and embolization of internal principal organ are the leading causes of death.Single embolectomy and anti-coagulation therapy are the mainstay of treatment for acute embolization.The major prognosis of limbs depended on the extent and range of ischemia and secondary treatment.

Objective To probe the essential aspect and its counter measure in training clinical medical postgraduate students.Methods Based on the review of recently publish papers related and teaching practice for years,the standpoint is put on the need of students in their long-term career after receiving degree.Results Medical ethics and medical information education should be the key point in the teaching plan.Teaching the students in accordance with their apti-tude should be based on their long-term need and the supervisors should be glad for and skilful at education.To put more cost of scientific research to students is in keeping with the China’s na-tional policy of invigorating the country through science and technology.Writing clinical case reports ought to be encouraged.Conclusion The noble medical ethics is the motivation force of gaining consummate medical skill.Up-to-date medical information and skill are the necessary capability in getting new knowledge and bringing forth new ideas.Writing case reports is to keep with the reality of students and may deepen the results of clinical observation and accumulate more data on typical case as well as give the bases to further research.

Based on both domestic and abroad research results concerning the local therapeutic efficacy, influence factors, survival time and prognosis of radiofrequency ablation (RFA) in treating recurrent hepatocellular carcinoma (HCC), this paper aims to make a review of medical literatures about RFA treatment of recurrent HCC that were published in Chinese and in English during the period from 2005 to 2014, and to analyze the related factors that may influence the local therapeutic efficacy and survival rate. The results indicate that the recurrent tumor size, tumor number, recurrence interval, serum alpha fetoprotein (AFP) level, serum prothrombin, etc. are important factors that will affect the therapeutic efficacy of recurrent HCC. At the same time, the results point out that the study of imaging predictors can help suggest the different recurrent types, which is very useful in making individualized follow-up strategy and in monitoring tumor recurrence. Local treatment, with RFA being the main method, together with comprehensive therapies, including other new technologies and new drugs, will improve the current clinical situation in treating recurrent HCC.

Objective: To investigate the effects of immunotherapy on PRA, TGF-β and CD4+CD25+Foxp3+ nTreg cells in women with unexplained recurrent spontaneous abortion. Methods:We detect the level of PRA,TGF-βin serum and the expression of nTreg cells in peripheral blood of pregnant, non pregnant and natural fertility women by enzyme immunoassay and flow cytometry. Results:After immunotherapy,the median level of PRA and TGF-βin non pregnant group was lower than that in pregnant group(27. 5%,107. 7 pg/L vs 68. 75%,189. 9 pg/L,P<0. 01). Compared to pregnant group,the median expression rate of nTreg cells were lower in non pregnant group(5. 05% vs 8. 05%,P<0. 01). Conclusion:The PRA,TGF-βand nTreg cells are critical factors for pregnancy in RSA patients. It is helpful to identify and judge the effect of immunotherapy by detect the level of panel reactive antibodies,TGF-β in serum and the expression rate of nTreg cells in peripheral blood.

Thyroid-associated ophthalmopathy (TAO) is an inflammatory eye disease associated with thyroid autoimmune disorder.The traditional treatments have yielded limited efficacy but with some side effects.Recently,researches have shown that some new immunosupressants may be used for the treatment of TAO with significantly improved symptoms,and reduction in clinical activity score.

Objective To retrospectively analyze the risk factors of recurrent groin hernia. Methods Data came from all hernia repairs recorded in our hospital between 1991 and 2001. A total of 1 082 cases of groin hernia was analyzed through Cox proportional hazard model to determine the relative risks between recurrence and mode of admission, types of groin hernia, repair methods (traditional/tension free hernioplasty), and post operative complications.Results From 1991 to 2001,1 082 groin hernia operations were performed in our hospital, 88.9% for primary hernia and 11.2% for recurrent hernia. As compared with traditional hernia repair methods, Lichtenstein’s tension free hernioplasty technique had less relative risk for recurrent hernia repair than that for primary hernia repair. Postoperative complications and indirect hernia were linked to an increased relative risk for recurrence. Conclusion There are many factors affecting the recurrence of inguinal hernia, but the use of tension free hernia repair may decrease re recurrence of recurrent hernia.

Objective To investigate the formaldehyde pollution in a tunnel. Methods The concentration of formaldehyde was determined in rooms for different function,in rooms with different number of furniture,in different position in a tunnel and at different time of using air cleaner in Oct. 2006. Results The total rate of exceed standard of formaldehyde level in the tunnel was 82.9%,the rate of exceed standard in the rooms disposed by all the furniture was 100%,the rate of exceed standard in the front of the tunnel was lowest (63.6%). Using the air cleaner,the rate of exceed standard decreased in degree. Conclusion The main source of formaldehyde pollution in a tunnel is furniture,formaldehyde is the main air pollutant in a tunnel.

Objective To review experimental study and clinical application of materials to bile duct repair and reconstruction.Methods Comparison of different materials was made between advantages and disadvantages.Results Synthetic grafts such as vitallium,teflon are easy to handle,but have no flexion,and have foreign body reaction.Although autogenous free tissues such as venous patch and peritonium are resistant to infection,they are likley to lead to bile duct stricture because of lacking adeuqate blood supply.Vascularized neibouring tissues for repearing bile duct defect have satisfactory results.Conclusions To avoid bile duct striccture,vary measures should be taken to repair bile duct defecs;for segmental loss of bile duct,end to end anastomosis or Roux-en-Y biliary jejunal reconstruction should be applied.

?AIM:To investigate the effects of Bevacizumab on the proliferation and the expression of E -Cadherin and fibronectin in human retinal pigment epithelial cell ( ARPE-19) in vitro.?METHODS: Different concentrations (0, 0.625, 1.25, 2.5, 5.0mg/mL) of bevacizumab were exposed to ARPE-19 cells, then cell viability was analyzed by CCK-8, cell cycle was determined by flow cytometry, and the expression of E-Cadherin and fibornectin was detected by Western blot and RT-PCR.?RESULTS:The concentration as 2.5mg/mL or 5.0mg/mL of bevacizumab was shown to effectively suppress the proliferation and cell cycle of ARPE-19 cell (P<0.05). In addition, 2.5mg/mL or 5.0mg/mL of bevacizumab could downregulate the expression of E-cadherin and promote the transcription of fibronection gene (P<0.05).?CONCLUSION:High concentration of bevacizumab was able to inhibit ARPE-19 proliferation, downregulate E-Cadherin expression and promote fibronectin expression, indicating epithelial-mesenchymal transition induced by bevacizumab in ARPE-19 cell.
