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.

Objective To study on the effects of Huaweishu granule on cisplatin-induced Beagle dog vomiting models and its mechanism.Methods Cisplatin-induced Beagle dog vomiting models were adopted as research object.The changes of vomiting frequency,latency,serum motilin content in the medulla oblongata and ileum,5-HT and substance P content of these models after using Hua weishu Granule were observed.Results ① Latent period of vomiting of the model group was (60.8±37.1)min; while this period was (137.3± 53.4)min,(122.8 ± 50.7) min,(l16.8±44.6)min,in the Huawei-shu low,medium and high dose group respectively,all showing a statistic difference than the model group (P＜0.05).②Frequency of vomiting in the model group was (270.3±51.8),while this frequence was (111.5±45.0) and (149.5±26.8) in Huawei-shu low and medium dose group respectively; ③ serum motilin in the model group was (0.354±0.098)ng/ml,while serum motilin in Huawei-shu low,medium and high dose group was (0.230±0.074) ng/ml,(0.235± 0.071) ng/ml,and (0.245± 0.062)ng/ml respectively,all lower than the model group (P＜ 0.05).④ Medulla oblongata 5-HT in the model group was (2.028 ±0.198)ng/ml,while medulla oblongata 5-HT in Huawei-shu low,medium and high dose group was (1.620±0.329)ng/ml,(1.194±0.386)ng/ml,and (1.269 ± 0.251) ng/ml respectively,all were lower than the model group (P＜0.05); ileum 5-HT in the model group was (1.634± 0.221)ng/ml,while ileum 5-HT in Huawei-shu low,medium and high dose group was (1.108±0.291)ng/ml,(1.194±0.386)ng/ml,and (1.269 ± 0.251) ng/ml respectively,all were lower than the model group(P＜0.05) ;⑤ ileal substance P content of the model group was (0.356±0.063)ng/ml,while ildeal P content in Huawei-shu low dose group was (0.274±0.064)ng/ml,lower than the model group than(P＜0.05).The medullary substance P content was (0.432±0.021)ng/ml in the model group,while medullary P content in Huawei-shu low,medium and high dose group was (0.370±0.040) ng/ml,(0.385±0.029) ng/ml,and (0.386± 0.041)ng/ml respectively,all were lower than the model group(P＜0.05).Conclusion Huawei-shu granule can prevent cisplatin-induced Beagle vomiting.

Objective Effectiveness of two kinds of thermochemotherapy infusion from intraarterial approach were studied in the grafted liver VX2 tumors of rabbit.Methods VX2 tumor model was established in 30 Newzland rabbit's livers.Percutaneous transfemoral hepatic arterial catheterization with fixation of the cathether tip inside the feeding vessel was carried out under DSA guidance.All 30 rabbits were divided into three groups(n=10 in each group),normal temperature 100 ml saline+Adriamycin(ADM)infusion(group 1),60℃100 ml saline+ADM continuous perfusion(group 2)and 60℃100 ml saline+ADM intermittent perfusion(group 3).After the perfusion,the lasting time periods of 43-45℃for tumor tissue of group 2 and 3 together with the concentrations of ADM within tumor's tissue were measured.Results Concentrations of ADM were shown as(12.013?2.237)?g/ml,(17.622?1.368)?g/ml,and(11.519?1.225)?g/ml for group 2, group 3 and group 1 respectively.60℃intermittent perfusion vs 60℃continuous perfusion showed P＜0.05, 60℃continuous pefusion vs normal temperature perfusion also showed P＞0.05. 43-45℃period lasting time (min)for 60℃continuous pefusion vs 60℃intermittent pefusion were(4.1?2.7)min and(11.3?3.3)min respectively,the latter was three times more than the former.There were no differences shown betwen the temperature,respiration and heart rate of group 2 and group 3.Conclusion Intermittent intraarterial perfusion thermochemotherapy is a more effective interventional management among all thermochemotherapies.

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.

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.
