Objective To evaluate the efficacy of catgut implantation at acupoint for acute ulcerative colitis and its safety.Methods Reference to Medline, EMbase, Cochrane Library, CBM, CNKI, VIP and Articles database, two independent investigators extracted data according to the inclusion and exclusion criteria, evaluated quality of included literature quality with criteria of the Cochrane Collaboration of randomized controlled trials, Meta analyzed the result by RevMan 5.2 software.Results Eight documents and 626 cases of patients were included. The clinical efficacy of Catgut Implantation group[RR=1.13,95%CI(1.05,1.20)] was better than the control group. Eight documents did not report complete remission rate, in which one reported recurrence rate, and the difference between Catgut Implantation group and control group was not statistically significant[RR=1.50, 95%CI(0.27,8.34)]. In the included documents, four didn’t show significant adverse reactions, three did not mention safety or adverse reactions, and two reported adverse reactions. In Catgut Implantation group, one had rejection, one got infection, one had halo pin, while one had halo pin and some patients experienced nausea, impaired liver function in control group.Conclusion Catgut Implantation on acute ulcerative colitis is better in terms of improving clinical efficacy. However, as the sample size is too small and drug safety is not clear, high-quality randomized controlled trials is still needed for further validation.

Objective To discuss the clinical application of preoperative transcatheter arterial chemoembolization (TACE) in treating squamous cell carcinoma of tongue. Methods A total of 26 patients with pathologically proved squamous cell carcinoma of tongue were enrolled in this study. Using Seldinger technique, lingual artery angiography and TACE were carried out in all patients. Radical resection of tongue cancer was performed in 2-3 weeks after TACE. Results Super-selective catheterization and TACE was successfully accomplished in all patients. After TACE the tumor size was significantly decreased in all patients. During the operation, clear lesion's border was observed, and the amount of blood loss was less than usual. Conclusion For the treatment of squamous cell carcinoma of tongue, preoperative superselective TACE is safe and effective;it can increase the opportunity of surgical resection, reduce the surgical damage, and improve the quality of life as well as the survival rate.

BACKGROUND:There are no available therapies for spinal cord ischemia-reperfusion injury, and stem cel transplantation is a focused topics. OBJECTIVE:To observe the therapeutic effect of hypoxia-inducible facotr-1α gene-modified umbilical cord blood mesenchymal stem cels (UC-MSCs) transplantedvia the infrarenal abdominal aorta on spinal cord ischemia-reperfusion injury in rats. METHODS:Thirty adult female Sprague-Dawley rats were randomly divided into three groups, with 10 rats in each group. The infrarenal abdominal aorta of rats was occluded surgicaly for 1 hour, and then the spinal cord reperfusion was restored. At 2 hours after reperfusion, 1 mL of 10% PBS, UC-MSCs suspension and hypoxia-inducible factor-1α-modified UC-MSCs suspension was injectedvia the infrarenal abdominal aorta, respectively, in the three groups. At 1, 6, 12 days after injection, Basso-Beattie-Bresnahan scores were recorded and western blot assay was used to detect hypoxia-inducible factor-1α protein expression in the spinal cord. The motor-evoked potential was determined at 12 days after injection. RESULTS AND CONCLUSION: Compared with the control group, the Basso-Beattie-Bresnahan scores were significantly higher (P < 0.05), the expression of hypoxia-inducible factor-1α protein in the spinal cord tissue was significantly increased (P < 0.05), the motor-evoked potential latency was shortened (P < 0.05) and the amplitude was increased (P< 0 .05) in the untransfected group and transfection group. Compared with the untransfected group, the Basso-Beattie-Bresnahan scores were significantly higher (P < 0.05), the expression of hypoxia-inducible factor-1α protein in the spinal cord tissue was significantly increased (P < 0.05), the motor-evoked potential latency was shortened (P < 0.05) and the amplitude was increased (P < 0 .05) in the transfection group. Above al, umbilical cord blood mesenchymal stem cel transplantation modified by hypoxia-inducible factor 1α has better effects on spinal cord ischemia-reperfusion injury.

Primary liver cancer is the third most common cause of death from cancer worldwide, and it is the second cause of cancer death in China. A variety of molecular markers and signaling pathways associated with hepatocarcinogenesis and tumor progression have been discovered in basic research in the recent decade. However, the 5 year survival of patients has not been remarkably improved, due in a large part to the late diagnosis and the limited treatment options. It seems that translational medicine should be accelerated to addres this problem. Translational medicine has been shown to bridge basic research and clinical practice in a B2B model: from bench to the bedside and bedside to the bench. It goes from the bench to bedside where theories emerging from preclinical experimentation are tested on patients, and from bedside to the bench, where information obtained from preliminary clinical sciences is used to refine the understanding of the biological principles. In liver cancer, diagnostic markers screening, development of molecular classification, and stratifying patients for targeted therapy are considered as exciting fields of translational medicine. The integration of basic and clinical sciences by translational medicine will improve not only the understanding of the underlying molecular mechanisms, but also the clinical outcomes in patients with primary liver cancer.

The incidence of hepatocellular carcinoma (HCC) has increased worldwide over the past two decades. Surgical resection and liver transplantation have been demonstrated as potentially curative treatment options, which could be considered in 30% -40% of HCC patients. Recent advancements of surgical treatment have focused not only on the surgical techpiques, but also the hepatic functional reserve evaluation, resectability assessment and the effects of biological characteristics of tumor on prognosis. There is no single variable to evaluate the hepatic functional reserve accurately. Combined Child-Pugh classification, ICGI5, portal vein pressure detection and remanent liver volume measurement are required prior to liver resection. The 5-year survival rate after liver resection for HCC is about 50%. The results are acceptable for some selected patients that underwent tumor resection with thrombectomy, including HCC with portal vein tumor thrombus or bile duct thrombosis. The choice of local resection or regular hepatectomy is still controversial although the former is commonly performed to treat HCC with cirrhosis, and the latter is applied to HCC patients without liver cirrhosis. The results of liver transplanta-tion for HCC are better than liver resection, and the Milan criteria is generally accepted. Any attempts to expand the selection criteria should be cautious because of organ shortage. Salvage transplantation for intrabepatic recurrence after liver resection may be a good choice in some resectable HCC. The recurrence and metastasis after surgical treatment are the main obstacles to achieve better results. Identification of predictive factors could be helpful to develop prevention strategies. Due to the importance of biological characteristics in tumor recurrence and metastasis, a molecular classification to predict prognosis of HCC patients will lead to a more personalized medicine. Targeting key molecules of biological pathways could optimize the therapeutic modality in HCC.

It is the prerequisite and foundation to set up the institutional ethics committee of organ transplantation that holds a proper structure for ethics committee to play a key role effectively.In terms of our reality and based on the successful practices and guidelines of international organizations of ethics committee,some suggestions and guidelines on reasonably standardizing the structure of ethics committee for organ transplantation in China are given to guarantee ethics committee to fulfill its target functions.

Cancer metastasis is considered as a complex process involving a series of sequential steps and a variety of molecalar signal transduction pathways.Tumor recurrence and metastasis are major obstacles for long-term survival of Liver cancer patients.Although the prognosis after recurrence and metastasis is dismal,the advancement of molecular researches of metastasis of liver cancer seems promising.In studies of origins of metastasis of liver cancer,the primary cancer cell and corresponding metastatic liver cancer cells share similar gene signature,which indicates that genes favoring metastasis progression are initiated in the primary tumors.The metastasis of liver cancer may be an early event in hepatic carcinogenesis and progression.Some molecular signatures have been developed to classify the metastatic potential of liver cancer.Furthermore,a variety of studies demonstrate that the tumor microenvironment instead of tumor cells plays a more important role in liver cancer metastasis.The pre-metastatic niche composed of non-tumoral cells may promote the cancer cell sedimentation and progression.The theory of cancer stem cell speculates that cancer stem cells were the real source of recurrent or metastatic tumors.Cancer stem cells will be one of the main targets of liver cancer treatment.The prevention and treatment of liver cancer recurrence or metastasis are quite difficult because liver cancer is resistant to traditional chemotherapy.Targeting the molecules involved in the metastasis of liver cancer WOuld be promising to cure those diseases.

OBJECTIVE: To assess the efficacy and safety of Sanjin tablets in the treatment of urinary tract infection. METHODS: Retrieved from electronic databases and references literatures by on-line or manual way, RCTs about Sanjin tablets in the treatment of urinary tract infection were collected. Related data were obtained and analyzed with evidence-based medical software statistically. RESULTS: 1 046 patients in 13 studies with were included. Two studies showed that Sanjin tablets had better effect than amoxicillin, ciprofloxacin, erythromycin and norfloxacin in the treatment of urinary tract infections. One study showed there was no significant difference in efficacy of Sanjin tablets and Modified juling tang. Other trials showed that there was no difference in efficacy between Sanjin tablets and Chinese herbal medicine, antibiotics. Three trials showed Sanjin tablets combined with Chinese herbal medicine or antibiotics had the same effect with antibiotics alone in the treatment of urinary tract infection. No severe ADR induced by Sanjin tablets was found in included studies. Funnel plot which assumed asymmetry indicated the existence of publication bias and unsatisfactory methodological quality. CONCLUSION: Few trials show efficacy of Sanjin tablets are better than antibiotics. Most of studies show that there is no significant difference between Sanjin tablets and antibiotics. At present no evidence indicate that efficacy of Sanjin tablet is superior to other drugs. The methodological quality of clinical trials of Sanjin tablets for urinary tract infections should be improved.
