Ninty-four newly diagnosed young type 2 diabetic patients were treated by acarbose, metformin or glipizide for 36 weeks. The results showed that these drugs had similar effects in reducing blood glucose. Acabose decreased postprandial insulin secretion and had higher safety and better compliance. It was appropriate to use in newly diagnosed young type 2 diabetic patients.

Objective To investigate the changes of panel reaction antibody (PRA) and the effects of HLA sensitized paths in patients waiting for renal transplantation.Methods PRA of 10 555 samples from 8926 renal transplant recipients in 51 transplant centers was analyzed.In 1991-1998 group,PRA was by using NIH-CDC technique,and in 1999-2010 group,PRA was detected by using ELISA.The effects of blood transfusion,pregnancy and transplantation on the PRA positive rate were analyzed.Results There were 1324 recipients positive for PRA in 8926 (14.83 ％ ).The average PRA positive rate in 1991 1998 group and 1999-2010 group was 18.17％ (513/2823) and 13.29％ (811/6103) repectively (P＜0.01).Among 1324 PRA positive recipients,the number of recipients with PRA of 1％-30％ and PRA of ≥30％ respectively accounted for 71.83％ and 28.17％.There were statistically significant differences in the PRA positive rate between the recipients receiving blood transfusion and those without blood transfusion (31.77％ vs 1.21％,P ＜ 0.01 ),between the recipients having pregnancy history and those without pregnancy history (24.64％ vs 7.19％,P＜ 0.01 ),and between primary transplant and re-transplant recipients (13.35 ％ vs 40.62％,P＜0.01).Conclusion In last 20 years, PRA in majority of PRA positive recipients was ＜ 30％ (low sensitized).Renal transplantation and blood transfusion were the important influencing factors that led to positive PRA,and pregnancy history was a related factor.

Objective:To establish the drug release determination conditions and method for phencynonate hydrochloride extended release tablets. Methods:The drug release of the tablets was determined by HPLC using a Diamonsil C18 (250 mm × 4. 6 mm, 5 μm) column with the mobile phase of acetonitrile-water-phosphoric acid-triethylamine (270∶400∶1. 3∶2), the detection wavelength was 220 nm, the flow rate was 1. 0 ml·min-1 , the column temperature was 30 ℃ and the injection volume was 20 μl. The effects of different release apparatus, release media and rotation speeds on the release of phencynonate hydrochloride extended-release tablets were studied as well. Results:The established drug release determination method had a good linear relationship within the range of 0. 3-5. 0 μg· ml-1(r=0. 999 8), and the average recovery was 100. 6%(RSD=1. 16%, n=15). Under the conditions of 900ml pH 3. 0 phos-phate buffer solution as the release medium, rotation speed of 50 r·min-1 and the settlement basket as the apparatus, the release be-havior of the product was complied with a zero-level model in vitro, and the release equation was as follows:Q=6. 141 2t-9. 328 7(r=0. 996). Conclusion:The method is simple, accurate and reliable, and suitable for the quality control of phencynonate hydrochlo-ride extended-release tablets.

In order to determine whether the variations in the calpain-10 gene constitutes risk of type 2 diabetes (T2DM) in Chinese, the frequency of UCSNP-43, 44 in 268 adults newly diagnosed with T2DM (according to the 1999 ADA criteria) and 153 non-diabetic control subjects was investigated. For all subjects, the height, weight, waist-to-hip ratio (W/H) and blood pressure, as well as following parameters were measured: (1) 75-g oral glucose tolerance test with insulin, C-peptide, HbA1c and blood lipid profiles; (2) Genomic DNA extracted from peripheral blood lymphocytes was genotyped for UCSNP-43 (calpain-10-g. 4852 G/A) and UCSNP-44 (calpain-10-g. 4841 T/C) by sequencing a polymerase chain reaction (PCR)-amplified fragment. PCR product was selected by single strand conformation polymorphism (SSCP) and then sequenced. The results showed that there was significant difference between T2DM group and normal control group in allele frequencies, haplotype frequencies, or haplotype combinations of UCSNP-43 and -44 either. But in newly diagnosed T2DM group, it was found that the individuals with the genotype UCSNP-44 T/C + C/C had significantly increased fasting and post-challenge insulin levels (Fins and P2hIns), consistent with reduced insulin sensitivity. In the BMI> 25 subgroup, the differences were even more significant. It was demonstrated that the Calpain-10 gene polymorphism UCSNP-44 was associated with insulin sensitivity and Fins and P2hIns in newly diagnosed T2DM, although Calpain-10 doesn't appear as a major diabetes susceptible gene in this population.

Objective:To investigate the effects of various bio-adhesive polymers on bio-adhesive characteristics and release rate of 5-fluorouracil HP-β-CD inclusion complex thermo-sensitive gels. Methods: Bio-adhesive polymer, such as hydroxypropylmethylcellu-lose ( HPMC) , sodium alginate ( SA) , sodium hyaluronat ( HA) ,carbopol and polycarbophil was respectively used to prepare the ther-mo-sensitive gels, and the bio-adhesive force was studied. The phosphate buffer (pH 7. 2) was used and the drug release characteris-tics were studied using dialysis technique. Results: The bio-adhesive force of the gels with 0. 2% polycarbophil was 32. 3 g·ml-1 , and the drug release time was prolonged to 8 h. There was no obvious difference in the dissolution among the gels with the various bio-adhesive polymers. Conclusion:Using 0. 2% polycarbophil as the bio-adhesive polymer, 5-fluorouracil HP-β-CD inclusion complex thermo-sensitive gels show good bio-adhesive force and prolonged drug release characteristics.

Objective: To develop 5-FU multiple emulsion entrapped into thermo-sensitive gel (5-FU-DEG) and detect the ab-sorption and transportation in Caco-2 cell monolayer model. Methods:The 5-FU multiple emulsion was prepared by a two-step emulsif-ying method. Poloxamer 407 (P407) was used as the thermo-sensitive material and sodium alginate (SA) was used as the bioadhesive material for the preparation of 5-FU-DEG. Caco-2 cell monolayer model was used to investigate the transportation and absorption of 5-FU. Results:5-FU-DEG gelled at the ambient temperature and turned into liquid below 10℃ The apparent permeability coefficient (Papp) of 5-FU-DEG was 1.47 ±0.11 ×10 -5(cm·s-1), which was about 6 times higher than that of 5-FU water solution(2.39 ± 0.21 ×10 -6 cm·s-1)(P<0.01). The cellular uptake rate of 5-FU-DEG was (17.1 ±0.24) %, which was 3.9 times greater than that of 5-FU water solution (4. 41 ± 0. 23%)(P<0. 01). Conclusion:5-FU-DEG can efficiently enhance the transportation and ab-sorption of drug in rectal site by using micro-emulsion technology combined with thermo-sensitive technology, which can be an effective rectal delivery system for 5-FU to treat rectal cancer.

Objective To analyze the application of clinicopathological features and LEF-1 in the diagnosis of solid pseudopapillary neoplasm of the pancreas (SPN).Methods Clinical and pathological data of 227 cases who were pathologically diagnosed as pancreatic SPN at Changhai Hospital from Jan 2000 to Dec 2015 were collected and analyzed.Immunochemical assay was used to detect the expression of LEF-1 in 132 cases of SPN, and the results were compared with β-catenin, which is most commonly used for diagnosing SPN.Results 81.9% of patients with SPN were female (186/227).Mean age at the onset was 34 years.Mean tumor size was 5.4 cm.48.5% tumors were localized in the pancreatic tail, and 33% in the head.46.3% tumors were cystic and solid, 42.3% were solid, and 11.4% were cystic.There were 2 cases of lymph node metastasis (0.9%), 15 cases of vascular tumor thrombus (6.6%), 14 cases of nerve invasion (6.2%), and 13 cases of adjacent organs invasion (5.7%) based on microscopic observations.Immunochemical analysis showed that 130 of 132 cases with SPN expressed LEF-1 with strong nuclear positivity, and the positivity rate was 98.5%.But no obvious expression of LEF-1 can be seen in normal pancreatic tissue and other pancreatic tumors.The specificity was 100%.The positivity of β-catenin expression in SPN was 96.6%(144/149), and β-catenin was positively expressed in only one case of acinar cell carcinoma.Tumors were completely removed by surgery in 165 cases, and the median follow-up was 51 months.By Oct 31, 2016, 162 patients (98.2%) survived, 5 had liver metastasis, and 1 had recurrence.Conclusions SPN is predominantly encountered in young female patients, and the clinical manifestations are not specific.LEF-1 can be used as a specific marker for the diagnosis and differentiation of SPN, which is more accurate than β-catenin.

Objective To investigate whether liraglutide treatment can prevent catch-up fat in high-fat dietinduced catch-up growth rats,and to discuss the possible underlying mechanisms.Methods Sixty-four SpragueDawley rats were stratified into 4 groups:normal control group,catch-up growth (CUG) group,catch-up growth with liraglutide treatment (CUGL) group,and catch-up growth with liraglutide plus exendin (9-39) treatment (CUGLE) group.All the catch-up growth animals underwent a4 week high-fat diet re-feeding phase after a4 week food restriction phase.Body weight and food intake were measured every day.At the end of food restriction and re-feeding,body composition was measured via Dual energy X-ray absorptiometry.After the rats were sacrificed,body fat distribution and plasma lipid levels were determined.Results By the end of catch-up growth,body weight,energy intake,Lee' s index,fat body mass,visceral adipose tissue/body weight,subcutaneous adipose tissue/body weight,triglyceride,free fatty acid,low density lipoprotein-cholesterol levels were lower in CUGL rats compared with CUG rats (all P＜0.01).There were no significant differences in energy intake,body composition,fat body mass,and blood lipid levels between CUGLE rats and CUG rats,while the weight of CUGLE rats was significantly lower than CUG ones.Conclusions Liraglutide infusion protects rats with high-fat diet induced catch-up growth from catch-up fat mainly via a glucagon-like peptide-1 receptor dependent manner.
