The high and continuing soaring incidence of diabetes may become a huge obstacle to China's development. The antidiabetic drug development is one way to solve the problem. Animal model is a powerful tool for drug development. This paper compares and analyzes the three kinds of animal models for antidiabetic drug development in replicating principle, methods and characteristic, then summarized the application in the research of traditional Chinese medicine. At the same time, the analysis of the market, application and clinical advantages of hypoglycemic medicine from traditional Chinese medicine, is given in this paper, based on the literature analysis. From the point of the clinic advantage embodiment and new drug development, this paper will provide advisory and assistance support for the anti-diabetic fighting with traditional Chinese medicine.

Surgical resection is the primary treatment for locally advanced rectal cancer,but the local recurrence rate of surgical resection is still at a high level. Preoperative and postoperative chemoradiotherapy not only decreases the local recurrence rate of surgical resection,but also elevates the survival rate and life quality. Recently,adjuvant chemoradiotherapy has been applied as the standard therapy for locally advanced rectal cancer. The application of targeted drugs,new chemotherapy drugs and rapid changing radiotherapy technology provide more approaches to the treatment of locally advanced rectal cancer.

The incidence of hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is very high,and the prognosis is often unsatisfactory.Currently,some therapy such as radiotherapy or radiation combined with interventional therapy are effective and worth attention.Radiation therapy was divided into external beam radiation therapy and internal beam radiation therapy according to different administration pathway.This article summarized the current situation and prospect of radiotherapy.

Objective:To establish a database for pelvic trauma in Hunan Province,and to start the work of multicenter pelvic trauma registry.Methods:To establish the database,literatures relevant to pelvic trauma were screened,the experiences from the established trauma database in China and abroad were learned,and the actual situations for pelvic trauma rescue in Hunan Province were considered.The database for pelvic trauma was established based on the PostgreSQL and the advanced programming language Java 1.6.Results:The complex procedure for pelvic trauma rescue was described structurally.The contents for the database included general patient information,injurious condition,prehospital rescue,conditions in admission,treatment in hospital,status on discharge,diagnosis,classification,complication,trauma scoring and therapeutic effect.The database can be accessed through the internet by browser/servicer.The functions for the database include patient information management,data export,history query,progress report,video-image management and personal information management.Conclusion:The database with whole life cycle pelvic trauma is successfully established for the first time in China.It is scientific,functional,practical,and user-friendly.

Objective To explore the clinical value of guide-wire shaping in subclavian vein catheter-ization.Methods Totally 400 patients requiring right subclavian vein catheterization were equally divided into two groups according to the clinic date: intervention group ( with guide-wire shaping , n =200 ) and control group (without guide-wire shaping, n=200).The catheterization was carried out by the same doctor .The rates of ectopic wire were compared between the two groups .Results The overall success rate of catheteriza-tion was 98.25%(393/400) [98.5% (197/200) in intervention group and 98.0% (196/200) in control group, P=0.500].The incidence of catheter displacement was 1.02%(2/197) in intervention group, which was significantly lower than that [7.14% (14/196)] in control group (P=0.002).Conclusion As a sim-ple procedure , guide-wire shaping can effectively prevent catheter displacement during catheterization .

Fomentation engineering is one of the modern biotechnologies. It has been intensively studied and widely applied in edible fungi. Based on the review of research history of liquid fermentation for edible fungi, the research status of liquid fermentation about edible fungi were summarized, and its application prospects on edible fungi production of our country were described in this paper.

Objective To evaluate the feasibility and safety of embedding the totally implantable venous access port (TIVAP) via the access of right brachiocephalic vein (BCV).Methods The clinical data of 493 patients,who underwent the placement of TIVAP by using right BCV route during the period from March 2013 to December 2015,were retrospectively analyzed.The patients included 137 males and 356 females,with a mean age of (47.3±13.2) years old (ranging from 29 to 78 years old).The puncture success rate and TIVAP indwelling procedure-related complications were analyzed.Results The technical success rate was 100％,the success rate of initial puncturing was 99％ (488/493).The mean operation time was (22.5± 8.3) minutes (range of 18-35 minutes).Mis-puncturing of artery happened in 3 patients (0.61％,3/493);and no severe complications such as hemothorax or pneumothorax occurred.After implantation,the patients carried TIVAP for 124-986 days,with a mean of (271.1±53.8) days.The incidence of complications was 2.25％ (11/488),including hemorrhage at port site (n=2),catheter-related infection (n=l),partial thrombosis (n=2),and formation of fibrous protein sheath (n=6).No serious complications such as displacement or rupture of catheter,or catheter pinch-off syndrome (POS),etc.were observed.Conclusion The implantation of TIVAP by using right BCV route has high puncturing success rate,the technique is safe and reliable,and it can provide another option of catheter access for the clinical performance of TIVAP implantation.

OBJECTIVETo investigate the gene mutation in the areas of pre core/core (Pre C/C) and basic core promotor (BCP) of HBV DNA and its clinical significance.

METHODSThe nt 1 735-1 965 segment of HBV DNA was amplified with PCR in 54 cases with chronic hepatitis B and 10 cases with post-hepatitis cirrhosis. Then the PCR product was sequenced.

RESULTSThere were 168 site mutations in 48.5% (33/68) cases with hepatitis B. The first ten mutation sites were nt 1 764 (58.8%), 1 762 (48.5%), 1 799 (21.0%), 1 766 (14.7%), 1 896 (13.2%), 1 754 (8.8%), 1 899 (8.8%), 1 768 (7.4%), 1 814 (7.4%) and 1 913 (7.4%). Three rare mutations of nt 1907, 1 922 and 1 923 were also detected. The mutations of nt 1 896, 1 764 and 1 762 were found in 16.7%, 35.2% and 35.2% of chronic hepatitis, and in 30.0%, 60.0% and 60.0% respectively of post-hepatitis cirrhosis cases. There was statistical significance between the two groups (P < 0.01).

CONCLUSIONThe mutations in the areas of Pre C/C and BCP of HBV DNA might possibly be associated with liver fibrosis. There are many mutation sites in HBV DNA and mutation occurs frequently, therefore gene sequencing is helpful to the design of gene chip and to clinical application.

BACKGROUNDCervicothoracic junction spinal tuberculosis (CJST) in children is uncommon, especially when accompanied by a huge abscess. However, its consequences can be severe. Because of the special anatomic location of the cervicothoracic junction, surgical treatment is difficult and rarely reported. The aim of this clinical study was to assess the effectiveness of combined anterior and posterior approaches for focal debridement, decompression, allografting and anterior instrumentation in the treatment of CJST in children.

METHODSTen pediatric CJST patients underwent focal debridement and cord decompression through combined anterior and posterior approaches. Then an appropriate allograft and titanium plate were applied to reconstruct the spine. The patients were asked to wear head-neck-chest braces for six months and received regular anti-tubercular drugs therapy for 12 months.

RESULTSThe patients were followed-up for an average of 26 months (range, 15-32 months). There was no recurrent tuberculous infection. The bone grafts incorporated well and the instrumentation was stable. Cervical and thoracic kyphosis was successfully corrected from 40° (range, 30-52°) before the operation to 18° (range, 12-26°) post-operation. Neurological function was improved in all patients.

CONCLUSIONSCombined anterior and posterior approaches for focal debridement, decompression, bone allografting and anterior instrumentation provided an effective means of treatment in children of CJST with a huge abscess in the posterior part of the vertebral body.
