Objective To explore the role of medical insurance in the treatment of the coronary heart disease(CHD) out-patients with or without medicare. Methods 92 CHD out-patients from the medicare department and 92 CHD out-patients from general department of Shandong Taishan Chronic Disease Hospital were investigated and comparatively analyzed on their clinical data in the past 1 year,including the times of hospital visiting,compliance with doctor's instruction,blood pressure,serum lipids and blood glucose control and evaluation of treatment effect based on their clinical symptoms and ECG records.Results The compliance with doctor's instruction,blood lipids,blood pressure control of out-patients in medicare department were significantly better than those in general department(P

Unilateral absence of a pulmonary artery in congenital heart disease may be considered as a risk factor for the surgical treatment of the basic anomaly especialy in cyanotic type of patients. This paper presents 9 such cases: tetralogy of Fallot in 7, dextrocardia and PDA in 1 and truncus arterio-sus with persistent left superior vena cave in one. Absence of left pulmonary artery was present in 7 cases and of right in two. Corrective surgical treatment were performed on 7 patients with tetralogy of Fallot. Two of them died in the early postoperative period. It was recommended that valved extracardiac conduit or woven dacron patch with pericardial monocusp be used for reconstruction of the outflow tract of right ventricle to alleviate the pulmonary regurgitation which was aggravated by higher pulmonary vascular resistance. Appropriate and active management of postoperative low cardiac output is also vital important.

There have been many studies on the structure and function of the high pathogenicity island since it was first discovered to be located on Yersinia . And it was detected to be present in a few different members of the family Enterobacteriaceae that are pathogenic to human. This review describes the Yersinia high pathogenicity island: structure,function and prevalence among pathogenic enterobacteriaceae.

Objective To identify homogenous clones of S.flexneri 2a, using gene distribution polymorphism of Shigella enterotoxinl and Shigella enterotoxin2 in a shigellosis outbreak by S.flexneri 2a. Methods 93 strains of S.flexneri 2a isolated from different areas, at different time were detected by Shigella enterotoxin1 and Shigella enterotoxin2 gene polymerase chain reaction to identify genetic type of S.flexneri 2a. Results The 93 strains of S.flexneri 2a were divided into 4 clones: ShET1(-)/ShET2(+)for 12 strains,ShET1(+)/ShET2(-)for 14 strains,ShET1(+)/ShET2(-)for 59 strains, ShET1(-)/ShET2(-)for 8 strains. Conclusions It is believed that Shigella enterotoxin1 and Shigella enterotoxin2 gene PCR analysis is a simple method for the primary screening of S.flexneri 2a.

Objective To study sodium cantharidinate induced apoptosis of human esophageal carcinoma Eca109 in vitro. Methods The change of human esophageal carcinoma Eca109 treated with sodium cantharidinate were analyzed by MTT and FCM assay. Results Human esophageal carcinoma Eca109 were treated with sodium cantharidinate for 24 h,the cell proliferation was obviously inhibited(P

This article elaborates some questions in the medical statistics experimental teaching and proposes several countermeasures such as: to strengthen teachers quality,to reform experiment teaching mode,to apply multimedia to teaching and to improve experiment examination forms.

Objective To research the Alzheimer disease(AD) patients' hippocampal structure and cognitive function with the susceptibility weighted imaging (SWI) and morphological measurement,and explore the changing regularity and correlation.Methods Sixty patients (divided equally into mild,moderate and major group as the condition of the severity of the AD) and 20 healthy control groups were scanned with SWI and T1MR,then the differences between AD and healthy controls were analyzed.Results The hippocampal volumes of AD patients were smaller than that of control group.The biggest variability occured in the major group(the left was Dunnett-t =-7.03,P ＜ 0.01 ;the right was Dunnett-t =-7.52,P ＜ 0.01),the moderate group was next(the left was Dunnett-t =-6.71,P ＜ 0.01 ; the right was Dunnett-t =-6.62,P ＜ 0.01) ;and the least variability occurred in the mild group.They did not achieve statistical significance (the left was Dunnett-t =-0.86,P＞ 0.05 ;the right was Dunnett-t =-0.68,P ＞ 0.05).The hippocampus vein' s length,diameter had reduced significantly in the mild group(Dunnett-t were-5.62,-7.02,P＜ 0.001),but the number of the branches was slightly increased,which was close to the statistical significance.(Dunnett-t =1.86,P ＞ 0.05).With the progress of the AD,all of the hippocampus vein's length,diameter,and branches were reduced significantly(the Dunnett-t of the moderate were-10.10,-11.40,-2.83,P＜0.05;the Dunnett-tofthe major were-11.69,-14.68,-5.74,P＜ 0.001).AD patients blood vessel diameter,length and cognitive have correlation(r =-0.034 ～-0.517,P ＜0.05,P ＜ 0.01).Conclusion The hippocampus vein and cognitive function function change in AD patients happened in the mild stages of disease.An important supplement to the MRI conventional sequences.

Objective To evaluate the repeatability and accuracy of semi-automated software OsiriX in the assessment of cartilage volume in normal knees on 3.0T MR. Methods Thirty right knees of healthy subjects were scanned twice with 3.0T MR using 3D-FLASH sequence with selective water excitation. Cartilage volume of the patellar compartment was determined with a validated open-source software OsiriX and manual segmentation separately by 3 observers using MRI data sets. After calculating the cartilage volumes, the segmentation processing times, the repeatability and volume results were compared between two segmentations. Results ①Compared with the manual segmentation, a time saving of at least 50% for cartilage volume measurement was achieved with OsiriX software segmentation. ②The interobserver repeatability error was 4.88% and 9.82% with OsiriX software segmentation and manual segmentation, respectively;the intraobserver repeatability error of high experienced observer was 0.77% and 1.29%, the interindividual repeatability range were 0.14%-1.11% and 0.52%-1.61%, respectively. The repeatability error of OsiriX software segmentaion was proved to be significantly smaller than manual segmentation (P＜0.05). ③System difference between results obtained with OsiriX software measurement and manual measurement was (-3.80±3.93)% and absolute pairwise difference was (4.68±2.70)%. There was no statistical difference between the volume results measured using two techniques (t=0.92, P=0.36). Conclusion Compared to manual segmentation, cartilage volume measurement with OsiriX semi-automated segmentation is faster and has higher inter- and intraobserver repeatability with relatively fixed standard. This technique may therefore be used for clinical and multi-center trials of large sample.
