10 cm respectively from the tumor),the metastatic rate of lymph nodes was 34.7%,2.5% and 1.7%,respectively.The metastatic rate of LN in right colon was significantly higher than that in left colon(52.0% vs 33.8%,P

Objective To discuss the safety management of hemodialysis equipment for safe and effective treatment to patients.Methods The management methods were summarized in aspects of the installation,utilization and maintenance of hemodialysis equipment.Results The hemodialysis patients received the safe and effective treatment through the strict management and the standardized system.Conclusion The standardized management can not only reduce the unnecessary failures of the equipment,and prolong the service life,but also increase the utilization rate of the equipment,and provide the best,safest and most satisfactory treatment for patients.

Objective To investigate effects of cerebral isehemic preconditioning on neurological function,in- farct volume,and the expression of caspase-3 in brain issue after brain ischemia again,and to investigate the brain protection mechanism produced by cerebral ischemia preconditioning.Methods 48 healthy male Sprague-Dawley (SD)rats(weighted 200～250g)were randomly divided into 2 groups:ischemia group(n=24),ischemia precondi- tioning group(namely preconditioning group,n=24).Each group was divided into 4 subgroups according to 6h,1d, 2d,4d after ischemia again.Results At the same point of time after ischemia,neurological deficit in preconditioning group was much less than that in ischemia group,the difference was significant(P

Objective:To investigate effects of depside salt from salvia miltiorrhiza(DSSM)on the dental pulp of rats under repeated exposure to +Gz acceleration.Methods:27 male SD rats were randomly divided into 9 groups(n =3).The rats in negative control group was only fixed with rats kept-keeling device,in positive control group were exposed to +5 Gz and +10 Gz respectively for 30 s each time,5 times per day,4 days per week,for 3 consecutive weeks.The rats in other groups were respectively given DSSMat 2,6 and 18 mg/kg respectively 30 min before each +Gz exposure.The rats in negative and positive control groups were injected with 0.9%sodium chloride solution 30 min prior to +Gz exposure.After the experiment,The pulp changes were observed by HE staining.Real time qPCR was applied to determine the relative expression of heat sheck protein(HSP70)mRNA.Results:+Gz exposure decreased the activity degree of the rats,and resulted in damage of rat dental pulp.With the increase of +Gz value,the relative expression of HSP70 mRNA was increased(P ＜0.05).HSP70 mRNA expression in drug groups was less than that in their own positive control groups,but showed statistical significance only in the 18 mg/kg and +10 Gz group(P ＜0.05).Conclusion:+Gz exposure may dam-age dental pulp.DSSMhas certain protective effect under +Gz exposure.

Objective To measure and analyze the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need (WISN)method,for reference of the government in building family doctor interdisciplinary teams.Methods 150 community health centers in 16 provinces were selected.The related data from 150 centers were collected to analyze the population served by each family doctor,and the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need(WISN)method.Results There were 10 721 community health professionals in the sample centers which provide 132.14 million standard equivalents of service to the public.1 9 6 1 6 community health professionals were needed to ensure the quality of service and no extra workload after work for professionals.Averagely,each family doctor can serve 1 558 residents,who needs 1.3~1.5 nurses or public health workers.Conclusions A huge gap was found for community health professionals.The population served by each family doctor should be lowered compared to the governmental requirement and more nurses should be introduced to the family doctor interdisciplinary team.

Objective To explore the clinical characteristics of coronary heart disease (CHD) companied by type-2 diabetes mellitus (DM) and features of their coronary angiographies. Methods The data of clinical characteristics and coronary angiography results of 108 CHD cases with T2DM and 103 CHD cases without T2DM were compared and analyzed. Results Compared with the cases of CHD without diabetes mellitus, the cases of CHD with T2DM exhibited significantly increased incidence rates of hypertension and dyslipidemia. The body mass index and serum uric acid level also increased obviously. The main manifestation of dyslipidemia of CHD patients with T2DM was the higher levels of triglycerides and lower level of serum high-density lipoprotein cholesterol. And the severe coronary artery disease and lower left ventricular ejection fraction were often found in CHD patients with T2DM Conclusion CHD patients with type-2 DM tend to have multiple cardiovascular-risk factors, and often have multi-branches lesion and more severe lesions.To treat cardiovascular risk factors actively is very important to prevent the CHD and improve its prognosis.

Objective To study the mechanism of calcium oxalate monohydrate and calcium oxalate dihydrate stone formation. Methods 258 urinary stones were examined by infrared spectrophotometry, from which, 20 patients with calcium oxalate monohydrate stones (COM) and 10 patients with calcium oxlate dihydrate stones (COD) were selected for the study of some urinary parameters. The statistical study was carried out with SPSS t test . Results The urinary excretions of both calcium and phosphate varied obviously between the two groups of patients.In the COM group,the urinary calcium was (4.83?1.98)mmol/24h whereas in COD group it was (9.88?4.28)mmol/24h,( P

Objective To evaluate the modified POSSUM surgical scoring system in urologic surgery patients over 70. Methods 180 patients over 70 were retrospectively analyzed with the mo dified POSSUM surgical scoring system.A comparison between the observed and the predicted morbidity was made. Results In the complication group and noncomplication group,the mean age of the patients were 74.9?4.1 and 74.7?3.6,the mean length of stay were (42.1?4.2)d and (28.7? 14.2 )d,respectively.In the complication group,both the physiological scores and the operative severity scores of POSSUM scoring system were significantly higher than the no complication group ( 22.0 ? 4.1 vs 20.1?3.9 in pysiological score and 11.7?4.3 vs 10.3?3.5 in operative severity score, P
