Objective To investigate the relationship between Atherogenic Index of Plasma(AIP) and the dorsalis pedis artery atherosclerosis in type 2 diabetes. Methods One hundred and twenty-seven patients with type 2 diabetes and 33 healthy individuals were included in the study. The diabetic patients were devided into 2 groups, with( n = 66) or without ( n = 61 ) atherosclerosis. The intima media thickness (IMT) of dorsalis pedis artery were measured by B-mode Doppler ultrasonography. The triglyceride(TG) ,high density lipoproteincholesterol(HDL-C) and other glucolipid metabolic indices were measured in all patients. The AIP was defined as the log value of TG/HDL-C ratio. The one-way ANOVA test was performed to determine the differences among three groups. The relationships between IMT and the other indicators were assessed using Pearson bivariate correlations analysis. The optimal operating point of AIP to diagnose the dorsalis pedis artery atherosclerosis in type 2 diabetes was obtained by drawing ROC curve. Results The AIP value in atherosclerosis diabetic patients,no-atherosclerosis diabetic patients and healthy subjects were 0. 229 ± 0. 132,0. 112 ± 0. 074 and -0. 045 ± 0. 033 respectively. The IMT value were (0. 71 ± 0. 24 ) mm, (0. 49 ± 0. 09 ) mm and (0. 34 ± 0. 15 ) mm respectively. Both indices shown statistical differences among the three groups (Ps = 0. 001 respectively). After adjusting for potential influence factors, AIP showed positive correlation with IMT( r = 0. 315, P = 0. 001 ). The OOP of AIP was 0. 1671 ,the area under the curve was 0. 783. Conclusion AIP was well related to the dorsalis pedis artery atherosclerosis in type 2 diabetes,and the OOP of AIP had good diagnostic reference value in these patients.

Background and purpose:Cervix cancer is the second most common cancer in gynecologic malignant tumors. Chemotherapy has been used more and more lately, and concurrent chemo-radiotherapy are receiving increasing attention. In this study, we investigated the clinical effect of concurrent PCF chemotherapy plus radiotherapy for moderate and advanced cervical cancer. Methods:One hundred and ninty-six patients with moderate and advanced cervical cancer were randomly divided into two groups: only radiotherapy group and chemo-radiotherapy group (98 cases for each group). Two groups underwent the same fractionation irradiation, the chemo-radiotherapy group was given PCF regimen that consisted of (DDP) at the dose of 20 mg daily intravenously for 1-5 days, (5-FU) at the dose of 500 mg daily for 1,3,5 days and (CTX) at the dose of 400 mg daily for 2,4 day for 2-4 cycles. Both groups received radiotherapy with 30 Gy first and were irradiated by the combination of external radiotherapy plus intracavitary irradiation.Results:The immediate response rates of the two groups were 100 %, there was no statistical difference. The 5 year survival rate was 76.5 % in chemo-radiotherapy group and 50 % in only radiotherapy group (P

Objective To study the efficacy and safety of low-dose azithromycin with tiotropium bromide in the treatment of stable chronic obstructive pulmonary disease.Methods A hundred and ten patients were randomized into three groups:tiotropium bromide group (36 cases,group A),azithromycin with tiotropium bromide group(38 cases,group B)and control group(36 cases,group C).Patients in group A were given tiotropium bromide (18 μg,q,d )in addition to conventional treatment.The patients in group B were given lowdose azithromycin (250 mg,twice a week) in combined with tiotropium bromide.The patients in control group were given the conventional treatment only.The courses of treatment lasted for six months.Results Compared with the control group,the frequency of acute exacerbation in patients treated with azithromycin and tiotropium bromide was reduced remarkably ( 2.1 ± 0.6 and 4.9 ± 0.7,t =18.5061,P ＜ 0.05 ).The severity of clinic symptoms ( Cough 1.3 ± 0.5 vs.2.2 ± 0.6,P ＜ 0.05 ),expectoration ( 1.0 ± 0.2 vs.1.7 ± 0.3,P ＜ 0.05 ),anhelation ( 1.5 ± 0.8 vs.2.1 ± 0.6,t =3.6342,P ＜ 0.001 ) ],life quality ( 29 ± 8 vs.42 ± 11,P ＜ 0.05 ) and six-minutes walking distance( [ 370.00 ± 14.26 ] m vs.[ 290.00 ± 12.85 ] m,P ＜ 0.05 ) of the azithromycin with tiotropium bromide group were improved significantly when compared with control.Compared with the tiotropium bromide group,the frequency of acute exacerbation ( 2.1 ± 0.6 vs.3.2 ± 0.8,P ＜ 0.05 ),the severity of clinic symptoms (Cough 1.3 ±0.5 vs.1.8 ±0.4,P＜0.05),expectoration( 1.0 ±0.2 vs.1.3 ±0.3,P ＜0.05) and anhelation( 1.5 ±0.8 vs.1.9 ± 0.6,P ＜ 0.05 ) ],life quality ( 29 ± 8 vs.36 ± 10,P ＜ 0.05 ) and six-minutes walking distance ( [ 370.00 ± 14.26 ] m vs.[ 330.00 ± 13.76 ] m,P ＜ 0.05 ) were improved over those of tiotropium bromide group.Conclusion The long-term low-dose azithromycin in combinned with tiotropium bromide is good and safe in treating stable COPD.Therefore,it is worth of further clinical evaluation.

BACKGROUND:Glucocorticoids may induce local bone trabecular and bone marrow necrosis, femoral head col apse and deformation, thus resulting in hip dysfunction. However the pathological mechanisms and treatment of glucocorticoids-induced osteonecrosis of the femoral head remain unclear, and the pathogenesis mechanisms are controversial. The current studies focus on the understanding of the pathological mechanisms.
OBJECTIVE:To summary the research progress of adipogenic differentiation theory of glucocorticoids-induced osteonecrosis of the femoral head and the treatment.
METHODS:The first author searched literature from CNKI and PubMed database from 1988 to 2010, by using the key words is“Glucocorticoids, osteonecrosis of femoral head, bone marrow stromal stem cells, adipogenic differentiation, differentiation factors, treatment, choices”in English, and“glucocorticoids induced osteonecrosis of femoral head, adipogenic differentiation, treatment, research progress”in Chinese. Articles regarding the adipogenic differentiation theory of glucocorticoids-induced osteonecrosis of the femoral head and the treatment were included.
RESULTS AND CONCLUSION:A total of 112 literatures were screened out, according to inclusion and exclusion criteria for literature screening, 54 articles were included. Modern researches emphasize the celland molecular biology level, and show that the biological base of glucocorticoids-induced osteonecrosis of the femoral head is abnormal adipogenic differentiation of bone cells, glucocorticoids cause the variations of adipogenic differentiation factors, leading to adipogenic differentiation of bone marrow stromal cells. But glucocorticoids affects multiple differentiation factors, it may cause great error in the evaluation of the pathogenesis of glucocorticoids-induced osteonecrosis of the femoral head purely from one factor. The abuse of glucocorticoids is the leading cause for the osteonecrosis of femoral head. Further studies are needed to investigate the pathogenesis of osteonecrosis of the femoral head and treatment programs.

BACKGROUND:So far, inducible co-stimulator is the important costimulatory molecule family member. Inducible co-stimulator can promote the activation of T cel s proliferation and secretion, regulate Th1/Th2 cel polarization dependence, enhance B cel function which depend on the T cel s. So, blocking the inducible co-stimulator may result the inactivation and no reaction of cloning in T cel s, thus inducing the immune escape of tumor on the body.
OBJECTIVE:To build a plasmid expression of inducible co-stimulator Ig, in order to observe the expression in rat body.
METHODS:cDNA encoding the extracel ular domain of human inducible co-stimulator was prepared. The encode of the domain was fused with the gene of immunoglobulin IgG constant fragment (Ig) of encoding mouse, in order to build the inducible co-stimulator Ig fusion gene and the secreted eukaryotic expression vector pcDNA3-inducible co-stimulator Ig. Enzyme digestion of the recombinant and sequencing was performed, and then the positive liposome coated pcDNA3-inducible co-stimulator Ig was transferred into the muscle tissue of mouse right thigh. Western blot was used to detect the level of inducible co-stimulator Ig.
RESULTS AND CONCLUSION:The sequencing confirmed that the size of target gene fragment pcDNA3-inducible co-stimulator Ig plasmid was exactly the same with the sequence of inducible co-stimulator published on Genebank, which indicated the successful of plasmid construction. After transferred into the mouse for 7 days, the liposome coated pcDNA3-inducible co-stimulator Ig was positively expressed in the mice serum, which showed that pcDNA3-inducible co-stimulator Ig could be expressed in the rat muscle cel s. The results suggest that gene synthesis and recombinant technology can successful y construct the eukaryotic expression vector pcDNA3-inducible co-stimulator Ig.

Objective: To detect estrogen receptor α and β(ER-α, ER-β)protein expression in different age of mouse thymus.Methods:Protein expression of ER-α and ER-β in thymus was analyzed via immunohistochemistry.Moreover,the relationship between ER-α and cytokeratin 18(epithelial cell marker)was further tested through fluorescence double-staining.Results: Immunohistochemical analysis revealed that both ER-α and β protein was found in nuclei of some thymocytes of 3 month mice.However,expression of ER-β was absence while ER-α was still positive in aged mice, such as 12 months and 16 months old.Double staining further confirmed that lots of ER-α/β positive cells were Foxp3 negative cells.Conclusion: Expression of ER-β is absent while ER-α is still positive in thymus of aged mice, which indicates ER-α is the critical estrogen receptor that involves in thymic involution.Moreover, ER-α/β do not participate in Treg development within thymus.
