Objective To investigate the effects of new compound traditional Chinese medicine prepatations Banxiao capsule on the mobilization of endothelial progenitor cells ( EPCs) .Methods After EPCs from mouse bone marrow treated with variable dose of Banxiao capsule, we detected the proliferation by CCK-8 assay, quantified the number of CD34/Flk-1 double positive cells by flow cytometric analysis, evaluated the migratory function of EPCs by transwell chamber assay, and studied the protein level of Bcl-2/Bax by Western blot analysis.Results Compared with untreated group, the proliferation potential of EPCs in Banxiao low dose (20μg/ml) and high dose (200μg/ml) group was increased(P<0.05), the number of CD34/Flk-1 double positive cells were increased (P<0.05), migrative activity of EPCs was increased (P<0.05),the level of Bcl-2 protein were increased, and the level of Bax protein were decreased.Con-clusion Banxiao capsule can enhance proliferation of EPCs through up-regulating of expression of Bcl-2/Bax.

NK cells can be divided into two subsets based on CD27 expression:CD27hiNK cells and CD27loNK cells.NK cells can be further divided into four subsets based on CD27 and CD11b: CD11bloCD27lo,CD11bloCD27hi,CD11bhiCD27hi and CD11bhiCD27lo.These subsets in different development stages have their own phenotypes and functions.In mice,NK cell developing pathway is through CD11bloCD27lo→CD11bloCD27hi→CD11bhiCD27hi→CD11bhiCD27lo.CD27 can also be used to divide human NK cells into two subsets which are comparable to those of mice.

Objective To explore the clinical significance of the footprints and lateral X-rays in weight loading in evaluating the rehabilitation of talipes valgus in the children with cerebral palsy.Methods One hundred footprints of 56 children who were cerebral palsy with talipes valgus in the hospital-community-family-based rehabilitation mode were divided into light,middle and heavy types,and they were counted with two footprint-based approaches,and the two approaches were compared with chi-square criterion,and the dependability on consequence of the footprint and lateral X-rays in weight loading were analyzed.Results One hundred feet evaluated by the method of footprint were flatfeet radically,and the occurrence of flatfoot evaluated by three define lines were 11,57,32,respectively,and evaluated by footprint ratio were 6,7,87,respectively,but the degrees were different with two footprint-based approaches.There was a close correlation between two footprint-based approaches and lateral X-rays in weight loading.Conclusions Flat foot caused by talipes valgus can be evaluated by footprint in static state,while the development of bones of foot and the constitution of instep can be monitored on the lateral X-rays in weight loading.

It is necessary for the researchers to know the index and use it to search the literature of microbiology . This article is the overview of BIOSIS previews including it's organization structure, features and using guide.

Physical performance is an ability with which the sufferers of lumbar disc herniation(LDH) achieve daily work and basic physical activity,including daily activities(such as the diverting movement from standing to sitting),functioning state of nerves and muscles,dailyworking ability and walking gait,etc.;abilities of body performance relative to pains,such as walking ten meters with loads,sit-stand test and Tread mill walk,etc.Most of current rehabilitation evaluation may be influenced by the subjective factors of the examinee or the examiner,but intelligent device for energy expenditure and activity(IDEEA) may be helpful to evaluate physical performance of the LDH patients in a complete,quantity-fixing,systematic and dynamic way.

Objective To analyze electromyographic (EMG) activities of vastus medialis obliquus (VMO) and vastus lateralis (VL) in patients with patellofemoral pain syndrome (PFPS) before and after an exercise program.Methods 26 subjects with PFPS were randomly divided into the EMG biofeedback plus exercise group (group A) and exercise only group (group B) with 13 cases in each group. All patients in two groups were trained with family exercise program, but the patients of the group A used a EMG biofeedback while training. The relative activities of VMO and VL of all patients in two groups were assessed with the EMG apparatus for a continuous 6 hours period before and 8 weeks after training. At the same time the intensity of the knee pain was also assessed.Results There was no statistics difference in VMO/VL EMG ratio of the group B ( P>0.05), whereas the group A had significantly higher VMO/VL EMG ratio ( P<0.05).Conclusion The EMG biofeedback apparatus used in home exercise program of PFPS patients can improve the recruitment of VMO.

BackgroundDiabetic retinopathy (DR) is a progressive vision-threatening complication of diabetes mellitus,but its pathogenic mechanism is still unclear. Recent studies showed that it may be associated with the inflammation response of retinal capillary. Cytokines can cause induction of proinflammatory and adhesion molecules and thereby increase monocyte endothelial cell adhesion, which is now accepted as the early key event in the development of DR. ObjectiveThe present study was to determine the relationship between the stages of DR and the levels of serum vascular endothelial growth factor (VEGF) , interleukin-2 ( IL-2 ), tumor necrosis factor-alpha (TNF-α) in diabetic patients. Methods This was a pilot case-controlled study. Ninety patients with type 2 diabetes mellitus were included in this clinical trial and 30 healthy individuals were enrolled as controls. The patients were grouped into the non-diabetic retinopathy(NDR) group,background DR group and proliferative DR(PDR) group according to the results from ophthalmoscopic examination and fundus fluorescein angiography(FFA) ,with 30 patients for each group. The levels of serum VEGF,IL-2,TNF-α were assayed by ELISA and compared among the 4 groups.Written informed consent was obtained from each subject before received any related medical examination to this study. ResultsThe mean serum VEGF levels were(217.35±27. 87)ng/L,(298.31±49.26)ng/L,and(341.23±40. 18)ng/L, respectively, and mean serum IL-2 levels were( 12. 12± 1. 57 )ng/L, (16.43 ±2. 26 )ng/L, and (21.36±0. 86) ng/L,respectively and mean serum TNF-α levels were( 11.63±0. 94) ng/L, ( 17. 52±0. 65) ng/L,and(22. 01±0. 87 ) ng/L respectively in the patients with NDR ,background DR and PDR, showing significant differences from healthy controls with( 193.46±37. 39 ) ng/L for serum VEGF, ( 8. 99 ±0. 57 ) ng/L for serum IL-2 and ( 7.31 ±0. 52 ) ng/L for serum TNF-α ( F =126. 38, P＜0. 0 1 ;F =120. 37, P＜0. 01 ;F =99. 84, P＜0. 01 ). The levels of serum VEGF, IL-2, and TNF-α in the patients with the NDR,background DR and PDR were increased significantly. The level of serum VEGF showed the positively significant correlation with serum IL-2 level and TNF-α level ( r =0. 749, P ＜ 0.01 ; r =0. 631,P＜0. 01 ). The serum levels of VEGF, IL-2 and TNF-α showed a significantly positive correlation with the prolongation and severity of DR(r=0. 791 ,P＜0. 01 ;r=0. 665 ,P＜0. 01 ;r=0. 632,P＜0. 01 ). ConclusionsVEGF, IL-2 and TNF-α play active roles in the generation and development of diabetic retinopathy, and the level of serum VEGF is closely associated with the levels of serum IL-2 and TNF-α. during the development of DR.
