OBJECTIVETo investigate the effect of Liuwei Dihuang Soft Capsule(LDSC) and Ginkgo Leaf Tablet (GLT) on serum regulated upon activation, normal T cell expressed and secreted (RANTES) in the patients with diabetes mellitus type 2 (DM2).
METHODSForty patients with early stage DM2 were randomly assigned to two groups, 20 in each group. Based on the conventional treatment with hypoglycemic agents, patients in the treated group were treated with LDSC plus GLT additionally, and those in the placebo group with placebo for 6 months, respectively. The levels of serum RANTES, blood glucose, blood lipids and glycosylated hemoglobin, as well as micro-content of albumin in urine were measured before and after treatment.
RESULTSIn the treated group, the serum level of RANTES decreased significantly after treatment, and it was significantly lower as compared with that in the control group (P < 0.05).
CONCLUSIONSLDSC and GLT can decrease serum RANTES level in patients with DM2. They play a preventive and therapeutic role on diabetic complications by their anti-inflammatory effect.

BACKGROUND: At present, finite element analysis can be used to judge intertrochanteric fractures, but mostly limited in the distribution of stress. Finite element model of various intertrochanteric fractures has not been reported in detail.OBJECTIVE: To build various types of intertrochanteric fracture models with Hypermesh 14.0 and LS-DYNA software to simulate the falling-induced external force on proximal femur, and to evaluate the effect of models, and to analyze the biomechanical mechanism of intertrochanteric fractures. METHODS: Normal side CT image data of one case of elderly intertrochanteric fracture were collected and imported into Mimics software to establish the proximal femur geometric models, were then analyzed and operated by LZ-DYNA solver after imported into Geomagic studio 2013 and Hypermesh 14.0 for smoothing and meshing. Before analysis, the material parameters were set, the boundary conditions were confirmed, and given the loading parameters. The operating results were checked in Hyper View. RESULTS AND CONCLUSION: (1) The distribution of stress of proximal femur exactly matched to the previous study. EvansⅠtype intertrochanteric fracture model was obtained under continuous shear stresses, and six types of fractures were obtained by adjusting the load. (2) These results manifest that based on the Hypermesh 14.0 and LS-DYNA software, the finite element can well simulate the intertrochanteric fractures, and shear stress plays an important role in intertrochanteric fractures, which can provide experimental basis for the prevention and treatment of intertrochanteric fractures.

OBJECTIVETo select the best preparation method of vincristine transfersomes (VCR-T) and predict its possibility of being a new formulation of VCR.
METHODOrthogonal design was used to optimize the preparation methods on the basis of single factor pretests; and the permeation tests in vitro were performed in modified Franz diffusion cells.
RESULTThe optimum formula was: pH was equal to 7.3, the ratio of lecithin to sodium deoxycholate is 70/20, the weight of VCR is 10 mg, hydrating time is 30 minutes. The optimized solution was light yellow and transparent colloid solution. The VCR-T are spherical and smooth with average diameters of 94 nm and an encapsulation ratio of 90%. The test in vitro showed that VCR-T could permeat through mouse skin at zero rate with the cumulative penetrating quality amounting to 63.8%.
CONCLUSIONTransfersomes may become a promising carrier of VCR for clinic use.
