Objective:To investigate the effect and mechanism of transcription factor Foxp 3 on the proliferation and cell cycle of human lung adenocarcinoma cell line A 549.Methods:We knocked down the expression of Foxp 3 using siRNA.Foxp3 inhibition was detected by RT-PCR.Cell proliferation was detected by MTT.Cell cycle of A549 cells were detected by flow cytometry after the transfection of siRNA.Cell cycle-related checkpoint genes were filtered by RT-PCR.The regulation of Foxp3 on cell cycle-related checkpoint genes were detected by immunofluorescence and dual -luciferase reporter assay system.Results: The proliferation of A549 cells were inhibited after silencing Foxp3,and A549 cells were arrested in G0/G1 cycle.G1/S cycle checkpoint gene CCND1 was down regulated.Mechanism research show that Foxp 3 can regulate the expression of CCND 1 directly.Conclusion: Foxp3 can promote the proliferation of A549 cell line by up regulating G 1/S cycle checkpoint gene CCND 1.This provides a new target for the therapeutic targets of lung adenocarcinoma.

Objective To explore the mechanism of ginsenoside-Rh2(G-Rh2) on inhibition of glioma by identifying differential proteins with proteomic technique. Methods The total proteins were extracted from SHG-44 cells treated with 32 ?mol?L-1 G-Rh2 for 72 h and the cells in control group,then were subjected to two-dimensional gel electrophoresis.Only spots with a fold change equal or above 1.5 and P

Objective To study the effects of quercetin(QUE) on proliferation of rat glioma C6 cell line in vitro.Methods The cells were divided into 5 treatment groups(10,25,50,75 and 100 ?mol?L~(-1) QUE),blank control and menstruum control group.The rat C6 cells were cultivated to 1?10~6?mL~(-1) in the RPMI 1640 medium,then added into 96 holes board with various doses of QUE by 3 holes per group,and MTT assay was used to observe the proliferation of the cells treated for 24,48 and 72 h.The change of cell cycle was also observed by flow cytometry(FCM) after the cells were treated with 50 and 100 ?mol?L~(-1) QUE for 48 h.The changes of the protein P53 and Bcl-2 of C6 cells treated with 50 ?mol?L~(-1) QUE for 48 h were detected by immunocytochemical methods.(Results With) the augmentation of QUE and the extension of the treated time,the C6 cell growth was inhibited,the A values decreased and the cell number in G_0/G_l phase was increased,the cell numbers in S and G_2/M phases were cut down,and the decreased expression of Bcl-2 protein and the increased expression of P53 protein were also observed after treatment with QUE.Conclusion Inhibitory effect of QUE on C6 cell line is proved to be dependent on the treated time of the drug and the dose of QUE,and the induced apoptosis of C6 cells is implemented by the means of up-regulation of P53 protein expression and down-regulation of Bcl-2 protein expression.

Objective To investigate the possibility and mechanism of ~ 125 I in treatment of glioma. Methods SHG-44 glioma cells were cultivated in vitro, the inhibitory effect of ~ 125 I on SHG-44 cell proliferation was determined by MTT method. The stereotactic method was used to establish the rat intracranial glioma model. The MRI was performed at 1st week after implantation and ~ 125 I was implanted in the glioma area, the MRI was performed to measure the diameter of tumor 2 weeks after implantation. The rats were killed after 2 weeks ,PCNA gene experession was determined with immunohistological method both in control and experiment group.Results one week after implantation the glioma grew,the results of MTT method showed the growth of the SHG-44 was inhibited, ~ 125 I inhibited the expression of PCNA gene and enlonged the rat survival period. Conclusion ~ 125 I can inhibit the growth of glioma ,the mechanism may be concerned with its inhibitory effect on PCNA gene expression.

Objective To explore the CT and MR imaging characteristics of intracranial melanomas. Methods CT and MRI characteristics in five patients admitted to our hospital from June 1993 to June 2000 and diagnosed as intracranial melanomas were retrospectively analyzed. Results There were two cases of primary melanoma and three cases of secondary melanoma. All the cases were examined by CT. The lesions presented as high density in 4 cases, and low density in only 1 case. Four cases were examined by MRI. Short T 1 and short T 2 signals were found in 3 cases, and slightly long T 1 and short T 2 signal was found in 1 case. Conclusion There are some special characteristics of melanomas on the MR imaging, which are helpful to ensure the diagnosis and distinguish the primary melanomas from secondary melanomas.

Methods MTT colorimetric analysis was used to measure the inhibitory effect of OHAP-1 with different doses(2.5,5.0,and 10.0 mg?L-1) on C6 glioma cells .RT-PCR was used to evaluate the mRNA expressions of bcl-2 and bax genes.The activity of superoxide dismutase (SOD) and the level of maleicdialdehyde (MDA) in the C6 glioma cells were also examined. Results The proliferation of C6 glioma cells was significantly inhibited by different doses of OHAP-1(2.5,5.0,and 10.0 mg?L-1).The inhibitory rate were 49.77%,67.65%,and 76.42%,respectively.The inhibitory rate in 2.5,5.0, and 10.0 mg?L-1 groups were higher than that in control group(P

Objective To investigate the effect of HbA1c meeting the standard or not on microalbuminuria,blood lipids and liver enzymes in patients with type 2 diabetes.Methods A retrospective analysis was performed on 457 subjects who had type 2 diabetes.They were divided into substandard group and standard group according to HbA1c result.The general information and relevant laboratory indicators of patients were.collected and compared between two groups.Results The microalbuminuria,serum triglyceride and liver enzymes (glutamyl transpeptidase,alkaline phosphatase,aspertate aminotransferase) were significantly different between two groups [ (189.8 ± 235.3) mg/dl vs (38.9 ± 85.5) mg/dl,(2.64 ± 2.99) mmol/L vs (2.02 ± 1.50)mmol/L,(41.7 ±52.9)U/L vs (29.7 ±24.9)U/L,(83.6 ±28.6) U/L vs (74.3 ±25.8)U/L,(26.7 ±19.1)U/L vs (22.0 ±10.5) U/L,P ＜0.05].HbA1c level was positively correlated with microalbuminuria,glutamyl transpeptidase and alkaline phosphatase (r =0.209,0.115,0.11,P ＜0.01).The microalbuminuria was an independent risk factor of affecting HbA1c to reach the standard (OR = 1.009,P ＜0.05).Conclusions HbA1c meeting the standard or not can influence many factors except blood glucose.
