Vildagliptin is a potent and specific inhibitor of dipeptidyl peptidase 4,which has been implicated to enhance and prolong the physiological actions of incretion hormones including glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide.Vildagliptin is an orally administered drug and has been licensed for the treatment of type 2 diabetes mellitus.Vildagliptin monotherapy or in combination with other drugs can effectively lower glycosylated haemoglobin levels to a great extent.In addition,vildagliptin acts in a glucose-dependent manner,explaining its low risk of hypoglycemia.This drug has been proved well tolerated with few gastrointestinal side effects or oedema.Therefore vildagliptin is a promising new option for type 2 diabetic patients,and these patients would achieve better glycemic control and fewer complications in the long run.

OBJECTIVETo study the applied value of double joystick technique in reduction-internal fixation for femoral shaft fracture in adults.

METHODSThirty-four patients (24 males and 10 females) with femoral shaft fractures were treated with reduction assisted by double joystick technique and internal fixation with interlocking intramedullary nail from September 2010 to June 2013. The average age of the patients was 41 years old, ranged from 17 to 65 years old. The duration of the disease course ranged from 3 to 7 days, with a mean of 5 days. The fractures belonged to AO types 32A (5 cases), 32B (20 cases) and 32C (9 cases) and located in left femur for 18 patients and right femur for 16 patients. The patients were followed up, and fracture healing and complications were observed. The curative effect were evaluated according to Thorsen femur fracture evaluation standard.

RESULTSThe operative time ranged from 40 to 110 min (mean 75 min) and intraoperative blood loss ranged from 200 to 300 ml (mean 250 ml). All the patients obtained a good fracture reduction and were followed up for 12 to 24 months (mean 18 months) after the surgery. All the fractures united between 4 and 8 months with a mean of 5 months. No complications such as breakage of nail, infection, osteofascial compartment syndrome, refracture and fracture malunion were found. According to Thorsen femur fracture evaluation standard, 30 patients obtained an excellent result, 3 good and 1 fair.

CONCLUSIONIn surgery of reduction-internal fixation for femoral shaft fracture in adults, the use of double joystick technique obtains good reduction result, short operative time, less injury, high healing rate of bone fractures, less complications and good limbs function, so it is worthy of popularizing in clinic.

This paper described a microprocedure for the simultaneous determination of retinol (Vitamin A), alpha and gamma tocopherol (Vitamin E) in plasma by high performance liquid chromatography. A reversed-phase C18 column with precolumn was used. The mobile phase was water in methanol (2:98) and the flow rate was 1.8ml/min. An ultraviolet detector with 300 nm was used. The chromatogram was completed in 12 min and the retinol, alpha and gamma tocopherol were quantitated by the peak area ratio and weight ratio using benzo (e) pyrene as an internal standard. The mean recovery of retinol and alpha tocopherol were 93.9% and 106.9% respectively. The coefficient of variation (CV%) were 5.2 for retinol, 4.8 for gamma tocopherol and 6.3 for alpha tocopherol. In order to assess the possibility of measuring pooled samples instead of individual samples, the value of individuals was compared with the value of the pooled sample. The results showed that the pool values and the mean ? SD of the 25 individuals compared very favourably.6500 blood samples were collected from both sexes and 130 communities of 65 counties. The plasma retinol and tocopherols were analyzed. The average plasma retinol value (X?SD,?g/dl) was 52 ?9.2 for male and 41 ?6.8 for female. The average plasma alpha tocopherol value (X?SD) was 703?108 for male and 735?101 for female. The mean ? SD (?g/dl) of total vitamin E were 750 ? 124 and 776 ?104 respectively for male and female.

Using the IL—6 dependent hybridoma cell line KD83, we investigated the relationship between KNA—anti—DNA immune complexes(DNA—anti—DNAICs)from the sera of lupus nephritis patients and interleukin 6 (IL—6) production by mouse glomerular mesangial cells cultured in vitro. The results show that DNA—anti—DNA IgM and DNA—anti—DNA IgG and DNA—anti—DNA IgM all enhance IL—6 production by mesangial cells; of those DNA—anti—DNA IC, the effect of DNA—anti—DNA IgM on IL—6 production by mesangial cells was significant. This enhanced production of IL—6 by mesangial cells was dependent on concentration of DAN—anti—DNA ICs.

Objective To analyze the immunization failure factors of 18 exposed rabies.Methods A statistical analysis factors is based on processing the exposed local wounds, the application of anti-serum, vaccines, wound area, incubation period, and compared to immune cases. Results Eighteen people, exposed immunization failure cases, scattered in the rural area(town). Thire age distribution is in all age groups during 2~83 years old and sex ratio of the men and women is 1:0.8.The short incubation period(28 days) accountered for 77.8%(14/18);Among by 61.5% people was bitten in neck accounter for 91.7%(10/12);Nine cases went to the village and town hospital to deal with the wound ,but only one case used rabies virus serums. Vaccines made in China are rat kidney(five cases) and refined Vero(8 cases), at the sane time the other five types made in China were unkown. Conclusions The most effective way to reduce the incidence of short incubation period is to strengthen management and immunization of animals such as dog, and to apply exposed former immunization in the epidemic area. At the same time, the key to reduce exposed immunization failure is exposed dealing in right ways, the muscle injection with anti-virus serums or immune globulin, and application of vaccine.

Objective To construct a recombinant strain which expresses adhesin AlpA of Helicobacter pylori(H.pylori) and to study the immunogenicity of adhesin AlpA. Methods The adhesin AlpA DNA was amplified by PCR and inserted into the prokaryotie expression vector pET-22b(+)and expressed in the BL21(DE3) E.coli strain. Adhesin AlpA immunogenicity was studied by Western blot test. Results DNA sequence analysis showed that the sequence of adhesin AlpA DNA was almost the same as that of the published by GenBank. The adhesin AlpA recombinant protein accounted for 31.9% of the total bacterial protein. Western blot analysis of rAlpA confirmed that it could be specially recognized by serum from rabbit immunized with AlpA itself and H.pylori infected patients. Conclusion Cloning and high-expression of adhesin AlpA and primary confirmation of its immunogenicity lay the foundation for H.pylori gene engineering vaccine preparation and adhering mechanism research.

Objective To investigate the effect of diazepam on blood-brain barrier ( BBB ) after radiation-induced brain injury. Methods Two hundred and forty healthy male SD rats weighing 240-270 g were randomly divided into 4 group with 60 animals in each group: Ⅰ D-R group received intraperitoneal diazepam 5 mg?kg-1 30 min before irradiation; Ⅱ N-R group received no diazepam before irradiation; Ⅲ D-SR group received intraperitoneal diazepam 5 mg? kg-1 30 min before sham irradiation and Ⅳ N-SR group received no diazepam before sham irradiation. The animals were placed in a prone position awake without any anesthetics. The whole brain was irradiated by 4 MeV electron beam at a single dose of 30 Gy. The changes in BBB were assessed by (1) magnetic resonance imaging (MRI) with the T1-weighted images, T2-weighted images and MRI enhancement images induced by Gd-DTPA; (2) Evans blue (EB) assay; 2% EB 3 ml?kg-1 was injected via femoral vein and 3 h later the animals were decapitated and EB content in the brain tissue was determined by spectrophotometry; (3) The expression of vascular endothelial growth factor (VEGF) in the brain tissue determined by immuno-histochemistry before irradiation ( T0 ) ( baseline) at 6 h (T1 ), 1 day ( T2 ) , 1 week ( T3 ) and 1 month ( T4 ) after irradiation.Results In group Ⅱ (no diazepam before irradiation) the signal intensity of T1-weighted images significantly decreased while the signal intensity of T2-weighted images and the enhancement rate significantly increased at T4. However in group Ⅰ (diazepam was given before irradiation) the changes in the MRI were significantly attenuated. The EB content at T1, T3 , T4 and the expression of VEGF at T1 , T, were significantly higher in group Ⅱ than in group Ⅰ . Conclusion Diazepam given before irradiation can protect BBB against irradiation injury by decreasing the expression of VEGF in the brain tissue and BBB permeability.
