Objective To study the effects of overexpression of HRAD17 on radiation-induced apoptosis of A549 cells.Methods Transfection of FLAC-tagged HRAD17 expression plasmid into human A549 cells was carried out and flow cytometry was employed tO observe the apoptotic effect.In addition,phosphorylation of p53 Ser46 was detected by Westem blot and the transcription of p53 AIP1 was measured by RT-PCR.Results Overexpression of HRAD17 gene significantly increased radiation-induced apoptosis of A549 cells.Further.Ser46 phosphorylation of P53 protein was increased and transcription of p53 AIP1 gene was elevated in cells overexpressing HRAD17.Conclusions HRAD17 protein can sensitize A549 cells to radiation-induced apoptosis in part by increasing p53 AIP1 expression.

Objective To elucidate the molecular mechanisms of sorafenib inhibitting human pe-ripheral blood T cells. Methods CFSE(5, 6-carboxyfluorescein diacetate succinimidyl ester) proliferation assay and MTS [3-(4, 5-diethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl) -2-( 4-sulfophenyl) -2H-etrazoli-um, inner salt] assay were used to examine the proliferation and the viability of T cells; Annexin V-FITC and PI staining was used to detect apoptosis; Flow cytometry was used to detect the expression of CD25, CD69; Western blot was used to detect the expression of cell cycle proteins; ELISA was used to detect the level of IL-2; Picryl chloride-induced delayed-type hypersensitivity model to be used to for the evaluation of in vivo immunocompetency. Results Sorafenib inhibited proliferation of human peripheral blood T cells in-duced by phytohemagglutinin(PHA) in a dose-dependent manner without inducing their apeptosis. Sorafenib caused human blood T cells arrest in the G_0/G_1 phase of the ceLl cycle. Sorafenib decreased CD25 and CD69 expressions and IL-2 production in human T cells. Sorafenib inhibited picryl chloride-induced delayed-type hypersensitivity in mice. Conclusion Sorafenib could inhibit proliferation and activation of peripheral blood T cells. These finding indicated that long term administration of sorafenib might lead to immunosuppressive effects.

Idiopathic membranous nephropathy(IMN) is one of the main pathology of nephrotic syndrome,and has a rising trend year by year.In recent years that IMN is organ specific autoimmune disease.Phospholipase A2 receptor(PLA2R) and thrombospondin type-1 domain containing 7A(THSD7A) are the two main antigens of IMN,which could be used to distinguish the IMN and secondary membranous nephropathy.The anti-PLA2R antibody and anti-THSD7A antibody are associated with diagnosis,severity and activity of the disease.The antibody titer and its change could be used to help deciding the beginning of therapy and the therapitive courses.

Objective To investigate roles of Homocysteine induced gene HCY2 in vascular smooth muscle cells (VSMC) Methods HCY2 was delivered into VSMC by replication defective adenovirus DNA fragmentation was investigated by DNA Laddering and cell death ELISA VSMC in sub G1 was detected by using flow cytometry Results DNA from VSMC transfected by HCY2 gene was cleaved into multiple nucleosomes and VSMC in sub G1 region increased after being infected with HCY2 Conclusion HCY2 is able to induce apoptosis in VSMC

Objective To evaluate the function of p27 gene on the neointimal formation after balloon injury in rabbit carotid artery. Methods The cultured vascular smooth muscle cells (VSMCs) were infected with Adp27. Using MTT assay we measured the proliferation of VSMCs. Balloon injured rabbit carotid arteries were also infected with Adp27, and then we evaluated the ratio of intima to media. Results MTT assay of rabbit VSMCs proliferation demonstrated an obvious inhibition in Adp27 treated group. And p27 overexpression had an effect on the cell cycle. It could induce cell cycle arrest in G1 phase and reduce the cells in S phase. Overexpression of p27 could also reduce the neointimal hyperplasia by 27.43%. Conclusion The p27 gene can reduce the neointimal formation after balloon injury in rabbit carotid artery effectively.

Objective To study the effects and mechanisms of diet-induced hyperhomocysteinemia on intimal hyperplasia of balloon-injured carotid arteries in rats. Methods Wistar rats were bred with 1 g/(kg?d) L-methionine. After 4 weeks, all animals underwent left common carotid arteries balloon denudation and the left common carotid arteries was extracted at day 14 and 28. The areas of carotid arteries intima and media, the proliferative index of smooth muscle cell and the percentage of reendothelization were measured and calculated. Results Intimal hyperplasia developed in all balloon-injuried arteries. The neointimal hyperplasia in the HHCY group was more obvious than that of the control group. The intimal thickness, neointimal area, Intima/Media area ratio were increased by 36%, 41%, 36% at 14 day and 33%, 30%, 21% at 28 day, respectively. Luminal area was decreased markedly in HHCY group. The percentage of intimal and medial PCNA positive cells increased by 1.7-fold and 2.3-fold at 14day. The percentage of endothelial covering area was decreased by 52% at 14day and 31% at 28day in HHCY group. Conclusion Diet induced hyperhomocysteinemia can stimulate SMC proliferation and inhibit endothelial regeneration, which leads to exacerbated intimal hyperplasia. This study implicates that homocysteine may be a significant risk factor for restenosis following vascular intervention.

0.05).After that,both systolic and diastolic function began to decrease.In 4 weeks after the operation,both the the maximum rate of left ventricular isovolumic systolic pressure + dp/dtmax and the maximum rate of left ventricular isovolumic diastolic pressure-dp/dtmax decreased to the lowest levels [(1249.89 ? 95.82) mm Hg/s and(-1316.40 ? 58.31) mm Hg/s,respectively];and then in 6 weeks after the operation,echocardiography showed that the left ventricular short axis fractional shortening FS reached the lowest level [(18.70 ? 3.83)%].Moreover,we found that the FS was highly related with the + dp/dtmax(r=0.864,P

Objective To observe the therapeutic effects of treating shingles with venesection and cuppingplus Yunnan White Powder external application and to observe the effect of mental intervention and nursing on clinical healing time.Methods 100 cases with shingles were randomly recruited into two treatment groups(Group A and Group B)and a control group.Both treatment groups were treated with venesection and cupping plus yunnan white powder external application,in addition,group B was treated with mental intervention and nursing care.The control group was treated with Aciclovir ointment.Results As compared with the control group,both treatment groups showed significant difierences in the time of relieving pain,removing swell,forming a scab,and healing(P＜0.01);Compared with group A,group B showed a shortened healing time with P＜0.05.Conclusion It is effective to treat shingles with venesection and cupping plus yunnan white powder.Mental Intervention and nursing can promote the healing time and improve the degree of satisfaction.

Objective To study the effects of Tripterygium Hypoglaucum Hutch(THH) and its extract(THW-4) on neointimal formation of rabbit carotid arteries after balloon angioplasty.Methods After injury of the common carotid arteries was set up by balloon angioplasty,the rabbits were divided into 3 groups and were given different treatment protocol including gastrogarage of THH(n=9),associated gastrogavage of THH with local administration of THW-4 into the injured arteries(n=9) and 0.25% DMSO saline local administration as the control(n=9).Neointimal fomation was evaluated on days after the procedure by proliferating all nuclear antigen(PCNA) and Evans Blue staining,and quantitative histomorphometric analysis was performed on 28 days.Results The PCNA-positive index in the neointima at day 14 after the procedure was reduced in the THH gastrogavage group and the THH/THW-4 group compared with the control(17.68%?5.27%,6.60%?2.52% vs 40.37%?7.12%,P
