Objective To investigate the effects of therapeutic equipment that aimed to improve cerebrovascular func?tion combined with electric standing bed on balance disorder following cerebellar infarction. Methods Fifty patients with balance disorder after cerebellar infarction were randomized into study and control groups. Agreed routine rehabilitation ther?apy including automatic standing bed and medication were given to both groups. In addition, therapeutic equipment that aim to improve cerebrovascular function were delivered to patients in study group. The effects were assessed using Fugl-Meyer balance function scale and Barthel index (BI) before and after 4 weeks of treatment. Results Study group and control group did not present difference between FM-B grade and BI before treatment (P>0.05). Both FM-B and BI were improved after treatment (P<0.05), but it improved more in study group than in control group (P<0.05). The total efficiency in treatment group is higher than that in control group (P<0.05). In the process of treatment, no obvious adverse reactions was observed. Conclusion The therapeutic equitment that aim to improve cerebrovascular function combined with automatic standing bed can improve balance disorder and daily activity after cerebellar infarction.

Objective To explore the role of mammalian target of rapamycin (mTOR) complex in the adriamycin induced the podecytes.Methods 1 μmol/L adriamycin (ADM) was used to induce mice podocytes for 24 hours and detected the apoptosis ratio,podosytes damage markers (Desmin) and the related expression of mTOR,then the role of mTOR was analysized in ADM induced podosytes.Results 1 umol/L ADM induced mice podosytes for 24 hours can make the podocytes damage.Compared with control group,podosytes activity declined(t =28.68,P ＜ 0.001),apoptosis rate increased both early (t =10.24,P =10.24) and late (t =4.26,P =4.26),and Desmin expression increased(t =6.16,P ＜0.001).mTOR expression decreased in ADM group.Compared with control group,both mTOR and phosphorylation mTOR expression decreased (t =3.57,P =3.57).mTOR downstream target molecular S6K1 and 4ebpl mRNA expression decreased(t =18.28,P ＜ 0.001).Conclusion ADM can make podosytes damage and the mechanism of ADM induced podosytes damage may be related to the decreasing mTOR and the low activity of mTOR.

Aninductivelycoupledplasmamassspectrometric(ICP-MS)methodbasedonquadrupole reaction/collision ( DRC) was developed for the determination of K,Na,Ca,Mg,Al,Cu,Zn,Pb,As and Mn in food. Samples were digested with HNO3 and H2 O2 followed by dilution with ultrapure water and then analyzed directly by ICP-MS. The signal sensitivity of high concentration element ( K, Na, Ca, Mg and Al ) was suppressed easily by adjusting the voltage parameters of DRC quadrupole ( Rpa) , and the food samples could be online diluted any multiples ( i. e. from one time to million times) according to the actual need. In order to eliminate mass spectral interferences of 40 Ar35 Cl+, the operational conditions of the DRC, working with CH4 as reaction gas, were optimized for 75 As. The limits of detection for the K, Na, Ca, Mg, Al varied from 0. 013-0. 027 mg/L, and Cu, Pb, Zn, As, Mnvaried from 0. 12-0. 61 μg/L. The accurate and reliable results were obtained for validation of the ICP-MS method with food reference material according to the national standard GBW10023 , GBW10015 , GBW10018 , GBW10017 , GBW10019 and GBW10024 . As the routine method in our laboratory, the satisfactory results indicate that it has great potential for the determination of low and high concentration level elements by one single analysis in various samples.

Objective:To probe into if human molecular adjuvant hC3d3 promote the immunogenicity of hCG? antigen to human immuno-competent cells on the basis of fusion protein.Methods:The isolated B cells, the combination of B cells and T cells, PBMC and Raji cells were treated in vitro respectively with 1, 10 and 100 nmol/L hCG?, hCG?-hC3d3 or PWM for 8-12 days. The cell proliferation was determined by incorporation of [3H] thymidine. The Ig levels in the 12-day culture supernatants were measured by indirect ELISA. The Ig-secreting cells in the 10-day cultured lymphocytes were detected by the enzyme-linked immunospot(ELISPOT) assay.Results:It was found that the proliferation of B cells, the combined B and T cells, PBMC and Raji following exposure to hCG?-C3d3 fusion protein was significantly higher than that of hCG? alone. The levels of total Ig the in 12-day culture supernatants of B cell, the combined B and T cells, and PBMC treated with 100 nmol/L hCG?-C3d3 fusion protein were 4-fold, 10-fold and 10.85-fold more than that of hCG? alone. The Ig-secreting cells were significantly increased after treated with hCG?-C3d3 fusion protein compared to the hCG? alone.Conclusion:The human molecular adjuvant hC3d3 improves the immunogenicity of hCG? in human immuno-competent cells if fused to the antigen.

Objective To investigate the effects of miR-335-5p on the proliferation and apoptosis of osteoblasts which were exposed to high glucose condition, and explore its possible molecular mechanisms. Methods MC3T3-E1 osteoblasts were divided into four groups:control group(5. 5 mmol/L glucose), high glucose group(HG group, 22. 0 mmol/L glucose), agomir-335-5p group(transfected with agomir-335-5p and exposed to 22. 0 mmol/L glucose) , and agomir negative control group( agomir NC group, transfected with agomir negative control and exposed to 22. 0 mmol/L glucose), cultured for 7 days. Cell proliferaton, cell apoptosis, expressions of miR-335-5p and dickkopfhomolog1(DKK1)mRNA,proteinlevelsofDKK1andcysteinylaspartate-specificproteinase-3(caspase-3) were detected using MTT, flow cytometry, quantitative realtime PCR and western blot, respectively. Results Compared with control group, the expression of miR-335-5p mRNA and cell proliferation in HG group were significantly decreased(P<0. 05), while cell apoptosis and the protein levels of DKK1 and caspase-3 were increased significantly(P<0. 05), the expression of DKK1 mRNA did not change (P>0. 05). The miR-335-5p mRNA expression and cell proliferation in agomir-335-5p group were higher than those in HG group and agomir NC group(P<0. 05). However, Cell apoptosis and the protein levels of DKK1 and caspase-3 in agomir-335-5p group were lower than those in HG group(P<0. 05). Conclusion High glucose inhibits the proliferation and induce the apoptosis of MC3T3-E1 osteoblast through decreasing the expression of miR-335-5p and subsequently increasing the DKK1 expression.

Objective To evaluate the feasibility and clinical efficacy of lateral femoral circumflex artery perforator flaps and fit together in the treatment of limbs complex wound surface.Methods From January 2010 to March 2012,use the characteristics that the descending branch of lateral femoral circumflex artery extend its branches over the flap,fascia and skin,to form lenticulostriate arteries,which contain 2 to 3 different species tissues fits together,flaps cover the important tissues such as vessel,nerves and bones.Fascia covers the tendinous tissues etc.Muscle can not only cover the tissues,but also fill in the space,and followed by skin grafting.This research was to perform the treatment for 4 cases of lacking limbs ring tissue,three cases of multiple wound surface,six cases of hand avulsion injury of skin and 9 cases of Gustilo grade-Ⅲ C.Results As for the 22 cases in the research,nineteen cases of flaps survived,the other 3 cases were necrosis with length of 1cm to 2 cm at distal and self-healed later.During 6 months to 2 years followed-up of 18 cases,external flaps were satisfactory,skin grafting over the fascia layers develops very well,smooth with great elasticity,no recoil,and no color change.Conclusion Lateral femoral circumflex artery is one of effective restoration methods for limbs with complex wound surface.

From the Chinese medicine point of view on the physiological functions of healthy atmosphere and vitality, healthy atmosphere and vitality of the relationship, we can know that healthy atmosphere and vitality has important role in the life activities of the body. They complement each other. In the pathogenesis of AIDS, AIDS epidemic poi-son has the characteristics of wounding healthy atmosphere. When it attacks the body upright, vitality will be injured firstly. Because of that it is inextricably linked with the characteristics of the AIDS epidemic poison and vitality physiological functions. Therefore, AIDS epidemic poison attacks healthy atmosphere and vitality co-exist, the injury of healthy atmosphere and vitality is throughout the whole process of AIDS .
