Objective To study the association of SNP of the AdipoR1 gene with T2DM in Xi’an population. Methods The amplification refractory mutation system(ARMS) analysis and gene sequencing were used to investigate the AdipoR1 gene polymorphism in 100 type 2 diabetics and 84 normal control subjects. Results (1) The genotype and allele frequencies of -106A/G, 5843A/G were not significantly different between type 2 diabetics and normal control subjects. (2) The diagnosis age of diabetics was significantly younger in AdipoR1 5843GG genotype group than in other genotype groups. Conclusions The data implicate that the AdipoR1 gene -106A/G and 5843A/G polymorphism may be not associated with pathogenesis of T2DM. AdipoR1 5843 GG genotype may be associated with the earlier diagnosis of T2DM

Objective To explore more safe and effective method for the treatment of common bile duct stones combined with cavernous transformation of the portal vein (CTPV).Methods We report 2 cases of post-treated patients in this series.In order to avoid severe bleeding caused by dissection of bile duct,we applied different methods to remove common bile duct stones compared with traditional operation.We removed common bile duct stones in one patient through cystic duct approach during operation.Two years later,we performed endoscopic duodenal incision (endoscopic sphincterotomy,EST) for him because of lower common bile duct stenosis with sand like stone.Another patient,on the other hand,we conducted the duodenal papilla incision during operation and removed common bile duct stones with choledochoscope through the bottom of common bile duct.Result Of the two patients,all of the three kinds of operation had good curative effects.Conclusions For the patients with common bile duct stones combined with CTPV,we should select appropriate treatments to avoid dissection of bile duct in front of the dilated and tortuous collateral veins during the operation,which is the key to guarantee the safety and success of the operation.EST is the preferred method of the treatment.Open operation with choledochoscopy via cystic duct approach or duodenal papilla incision through distal common bile duct to perform stone extraction also appears to be effective and safe.

Hepatic carcinomas were induced with the administration of diethyl-nitrosamine (DEN) in rats. The morphological changes of the liver tissues in the course of carcinogenesis could be divided into 3 successive stages: the nonspecific changes reacting to the drug toxicity, non-cancerous hyperplastic nodules of hepatocytes and ductular cystadenomatous lesions,and the lesions of genuine malignancy including hepatocellular carcinoma and cholangiocarcinoma.The ultrastructural alterations of hepatocellular carcinoma showed a complicate picture and were related to the differentiation of the tumor cells. In one case of cholangiocarcinoma, numerous cytoplasmic dense-core granules similar to the neurosecretary granules seen in apudoma were found in some of the tumor cells, which is postulated to be a special type of cholangiocarcinoma. On the basis of the results, Ihe histogenesis of the neoplasms after DEN administration is considered to originate from hyperplastic nodules of hepatic cells and ductular hyperplasia.

[Objective]To evaluate the application value of minimally invasive release operation about congenital vertical talus(CVT).[Method]All operation were operated with single method by author.Firstly,Achilles tendon,capsulotomy of the ankle and subtalar joint were released through a small straight posterior inside of Achilles tendon end point.Secondly,astragaloscaphoid and subtalar front joint were released bluntly through a straight posterior incision.Thirdly,based on circs subtalar joint were released through calcaneocuboid articulation outside foot.Then one K-wire were passed through the body of talus from its axis,and passed through instep after reposition of astragaloscaphoid joint.Two K-wires was passed through calcaneus to talus from planta.[Result]Eight cases were available for follow-up from 17 to 36 months(mean,28 months),follow-up results was evaluated by using a version of Adelaar and Kodros score,there were excellent result in 1 foot,good in 5,fair in 2.The presence of hindfoot valgus and forefoot abduce were noted in one foot,forefoot pronation was appeared in one foot.Two parameters-talar and calcaneus axis-first metalarsal base angles,calcaneus talus angles of eutopic and lateral radiograph were basally normal.[Conclusion]Operative reduction has been advocated as the only effective treatment for CVT,it is the best choice to use minimally invasive release operation for infant.

OBJECTIVE:To provide reference for the understanding of quality status of Insulin injection and improvement of related standards. METHODS:The statutory methods of Insulin injection were adopted to test 32 batches of samples(including ap-pearance,identification,capacity,visible foreign matter,sterility and potency determination of biological method). Consulting specification of other similar products,RP-HPLC was conducted to determine the related impurities,content and phenol in sam-ples;HPSEC was conducted to determine the high molecular weight proteins and atomic absorption spectrophotometry was conduct-ed to determine the Zn content. RESULTS:Results of all the 32 batches of samples were qualified by the test of statutory methods. According to the method of other similar products,the determination result of A21 desamido insulin was 15.6%-39.2% and general-ly greater than 5.0%, which was the highest limit of similar products;insulin was 93.2%-102.7%;protein polymer was 0.5%-0.6%;phenol was 2.34-2.51 mg/ml and Zn was 12.3-14.8 μg/100 U. CONCLUSIONS:The statutory specification of Insulin injection is short of many key specification items such as impurities and content determination;the contents of protein polymer, phenol and Zn were in good control;the contents of A21 desamido insulin are generally high,and stability of insulin main peak is relatively poor.

Cancer is one of the main causes of death for human beings. Clinical oncologists increasingly rely upon imaging for diagnosis, stage, response assessment, and follow-up in cancer patient. However, 18F-FDG is not a tumor specific agent, inflammation and infection also have intensive uptake of 18F-FDG, resulting in false positive diagnosis, and some tumors have low uptake of 18F-FDG or even do not uptake 18F-FDG, leading to false negative diagnosis. So it is urgent to develop non-18F-FDG novel tumor targeting agent. Recently, a large number of researches in vitro have demonstrated that berberine has anti-tumor activity against a variety of tumor cells by inducing tumor cell apoptosis through inhibition of mitochondrial respiratory chain etc. So far, there is no credible evidence of berberine targeting in tumor in vivo. We proposed a hypothesis that berberine has the characteristics of tumor targeting biodistribution in vivo, and verified the proposal by 18F-berberine PET/CT imaging in VX2 muscle tumor-bearing rabbit model. In this review, we intend to give an overview of the progress of berberine anticancer, the structural bases of berberine anticancer and the uderlying molecular mechanisms of berberine anticancer indentified so far. We also introduce the first visualization of 18F labeled berberine derivatives targeting tumor in VX2 muscle tumor-bearing rabbit model by PET/CT. These breakthrough findings suggest that 18F-berberine derivatives as a potential PET/CT tumor targeted molecular imaging agent may have important implications for cancer targeting therapy, molecular imaging and modernization of Traditional Chinese Medicine.
