One hundred and sixty non-diabetic patients with cerebral ischemia of primary onset were enrolled in the study. The patients were divided into impaired glucose tolerance (IGT) group and normal glucose tolerance (NGT) group according to the oral glucose tolerance test (OGTT). Carotid atherosclerosis and carotid artery stenosis were examined with vascular Doppler ultrasonic detection. The incidence rates of carotid atherosclerosis in IGT group and NGT group were 87. 5% (70/80)and 63.8% (51/80)respectively (χ2= 12.240,P <0.001);the incidence rates of carotid stenosis in IGT group and NGT group were 63.8% (51/80) and 47. 5 % (38/80), respectively(χ2 =4. 279, P =0. 039);the degree of carotid artery stenosis in IGT group was higher than that in NGT group(χ2= 21.95, P < 0. 01). The results indicate that IGT may be related to atherosclerosis and stenosis of carotid artery in cerebral ischemic patients.

As an income redistribution mechanism, the design of Urban Resident Basic Medical Insurance ( URBMI) should reflect the inclination to take care of vulnerable populations, such as people with chronic diseases and low incomes. Therefore, whether the healthcare services of vulnerable populations have been improved, is the most important indicator to determine the effectiveness of the URBMI. Using the DID model, this paper analyzes healthcare service utilization of invulnerable and vulnerable populations before and after the establishment of URBMI ( including both outpatient and inpatient) , based on the idea that these two populations have different socio-economic and health status. Then, based on the gap between the healthcare service utilization changes of different groups, we can measure the equity in URBMI. The results show that the establishment and implementation of URBMI has indeed narrowed the gap of invulnerable and vulnerable populations with different socio-economic and health status; health-care service utilization of vulnerable populations has increased significantly, and health status has significantly im-proved. From vertical and horizontal perspectives, the results prove that the establishment of URBMI has improved the equity of healthcare service utilization among different populations across China.

Objective To analyze the treatment and pathogenetic condition of chronic heart failure of coro -nary heart disease(CHD) and ventricular arrhythmia (VA).Methods 100 patients with chronic heart failure were collected to observe the treatment of chronic heart failure and pathogenetic condition of VA .Results 44 cases occured VA and 56 cases without VA in 100 patients.NT-proBNP(3 110.00 ±522.00)pg/mL of VA group was sig-nificantly higher than that (2 200.00 ±486.00)pg/mL of non-VA group(t=8.996,P<0.05).LVEF(0.25 ± 0.08) of VA group was lower than that of non -VA group(0.41 ±0.98) (t=11.625,P<0.05).The occurrence (100.00%) of premature ventricular contraction ( PVC) of ≥70mm group in left ventricular internal diameter (LVID) was higher than that of 60 -69mm group (60.87%),50 -59mm group (37.04%),40 -49mm group
(15.38%) with statistically significant(χ2 =5.853,12.532,27.375,all P<0.05).The amount(44.20 ±12.90)mg of use βreceptor blockers of amiodarone group was significantly lower than that of non -amiodarone group(44.20 ± 12.90)mg (t=5.284,P<0.05).Conclusion NT-proBNP of CHEF of CHD and VA patients will improve and amiodarone can reduce the amount of use anti -heart failure drug .

This study was designed to investigate the impact of ultra-filtration extract mixture from Astragals mongholicus (UEMAM) o radiosensitivity of H22 ascitic tumor in mice to 12C6+ ions radiation. The H22 ascitic tumor model was established in mice by intraperitoneal injection of 0.2 mL H22 ascitic cells. The animals were subsequently divided into 4 groups randomly, treated with normal saline, UEMAM, heavy ion beam radiotherapy and UEMAM plus heavy ion beam radiotherapy, respectively. The body weights, abdomen circumference of the mice were measured and the mouse behavior was monitored every day; survival time was recorded to evaluate life extension effect; flow cytometry technique was used to detect H22 cell apoptosis and cell cycle; protein levels of p53, Bax, Bcl-2 and cleaved Caspase-3 were analyzed by Western blot; the single cell gel electrophoresis was used to detect the level of deoxyribonucleic acid damage (DNA damage). The results suggest that UEMAM significantly increased survival time, and decreased body weights and abdomen circumference over the saline control group. The treatment increased cell apoptosis, cycle arrest and DNA damage compared to the saline control group. UEMAM significantly enhanced the therapeutic effect of heavy ion beam radiation in survival time, and decreased body weights and abdomen circumference in the tumor-baring mice. The combination increased cell apoptosis, cycle arrest and DNA damage compared to the radiotherapy group. The results of Western blot suggest that the treatment significantly enhanced p53-induced apoptotic signals. The experiment discovered that UEMAM could improve radiosensitivity of H22 ascitic tumor through activation of p53-mediated apoptotic signal pathway.

A total of 68 patients with histologically proven endometrial cancer were preoperatively evaluated with a 3.0 T magnetic resonance (MR) unit.Two radiologists interpreted the depth of myometrial invasion on T2-weighted and diffusion-weighted(DW) MR (b =700 s/mm2) imaging.Myometrial tumor spread was classified as superficial (＜ 50％) or deep (≥50％ myometrial thickness).Statistical methods included Kappa statistics for reader agreement,accuracy assessment and receiver operating characteristic analysis for diagnostic performance comparison.For assessing the depth of myometrial invasion,the diagnostic accuracy,sensitivity and specificity were as follows:T2-weighted imaging-reader 1st,61.8％,60.0％ and 65.2％;reader 2nd,66.2％,64.4％ and 69.6％ ; T2-weighted combined DW imaging-reader 1st,86.8％,84.4％and 91.3％ ; reader 2nd,89.7％,86.7％ and 95.7％.Reader agreement was excellent for T2-weighted combined DW imaging (Kappa =0.818).For assessing deep myometrial involvement,ROC analysis showed that the diagnostic accuracy was significantly higher on T2-weighted combined DW imaging than that on T2-weighted imaging.The AUC (area under the curve) values measured by two readers on T2-weighted and T2-weighted combined DW imagings were 0.626,0.879 and 0.670,0.912 respectively.The addition of 3.0T MR diffusion-weighted to T2-weighted imaging can improve the diagnostic performance of MR imaging in the assessment of myometrial invasion.

Objective To investigate the selective oncolytic role and antitumor action of a novel recombinant adenovirus containing E1A and IL-24 on hepatocellular carcinoma cell(HCC). Methods The recombinant adenovirus expressing IL-24 (Ad. HS4. AFP. E1A/IL-24) was constructed by using modified human alpha-fetoprotein (HS4-AFP) promoter to drive adenovirus E1A gene and II-24 gene.Cell Counting Kit-8 were performed to test the selective cytotoxicity of the virus in hepatocellular carcinoma cell lines SMMC-7721, Hep3B, MHCC97-H and hepatocyte cell line L02 . The mRNA and protein expression of IL-24 gene were detected by RT-PCR and western blot. Cell growth curves and Annexin V/PI assay were used to study cell proliferation and apoptosis of MHCC97-H. The anti-metastatic effects of the recombinant adenovirus were evaluated in cell adhesion, migration, and cell motion. Matrix metalloproteinase-2 (MMP-2) expression was examined by RT-PCR and zymography.Results Selective replications of Ad. HS4. AFP. E1A/IL-24 adenovirus were observed in over expression AFP cell line MHCC97-H, a highly metastatic potential HCC cell line but not in hepatocyte cell line L02. The mRNA and protein of IL-24 were also over expressed in MHCC97-H. This recombinant adenovirus also showed the significant oncolytic action on MHCC97-H but not on L02 (P＜0. 05). Besides, the recombinant adenovirus significantly inhibited MHCC97-H metastatic potential such as cell adhesion, migration and invasion as well(P＜0.01). Conclusion The selective oncolytic adenovirus expressing E1A and II-24 has a selective antitumor effect and play an inhibitory role in metastasis of HCC.
