Objective To investigate the effects of various dose of atorvastatin on intima-media thickness (IMT) of carotid and endothelial function in elderly patients with type 2 diabetes mellitus (T2DM).Methods One hundred and seventy-two elderly patients with T2DM were divided into three groups by random digits table method.Group A (63 cases) was treated with atorvastatin 10 mg/d,while group B (54 cases) was treated with atorvastatin 20 mg/d and group C (55 cases) was treated with atorvastatin 40 mg/d for 12 months.The serum levels of lipid,high-sensitive C reactive protein (hs-CRP),IMT of carotid and endothelial function were measured before and after treatment of 6,12 months.Results There were no significant differences in the levels of lipid,hs-CRP,IMT of carotid and endothelial function among three groups (P ＞0.05).The levels of total cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol and hs-CRP were decreased and high density lipoprotein cholesterol was increased after treatment of 6,12 months in three groups (P ＜ 0.05).The levels of TC,TG and hs-CRP after treatment of 12 months in group C were lower than those in group A and group B [(3.52 ± 0.55) mmol/L vs.(4.45 ± 0.71),(4.31 ± 0.75) mmol/L,(1.20 ±0.12) mmol/L vs.(1.64 ±0.18),(1.51 ±0.17) mmol/L,(4.22 ±0.28) mg/L vs.(5.34 ± 0.48),(5.02 ± 0.44) mg/L],and there were significant differences (P ＜ 0.05).IMT of carotid,Crouse scores of plaque and the incidence of carotid plaque after treatment of 12 months in group C were lower than those before treatment [(0.84 ±0.07) mm vs.(1.07 ±0.10) mm,(4.03 ± 1.14) scores vs.(4.34 ± 1.18) scores,41.8％(23/55) vs.78.2％(43/55)],and there were significant differences (P ＜ 0.05).The levels of endothelin and thromboxane B2 were markedly decreased in group C after treatment of 12 months [(68.48 ± 9.35) ng/L vs.(90.07 ± 10.19) ng/L,(80.08 ± 14.27) ng/L vs.(104.77 ± 12.36) ng/L],while the levels of nitric oxide and 6-Keto-PGF1α were increased [(72.28 ± 9.40)μ mol/L vs.(61.88 ± 10.01) μ mol/L,(72.39 ± 8.67) ng/L vs.(54.92 ± 10.78) ng/L],and there were significant differences(P＜0.05).After treatment of 12 months,the levels of endothelium-dependent dilation were significantly increased in three groups (P ＜ 0.05).The levels of endothelium-independent dilation in group B and group C were significantly increased after treatment of 12 months [(11.12 ± 1.00) ％ vs.(6.38 ± 0.49) ％,(13.43 ± 1.11) ％vs.(6.39 ± 0.52)％],and there were significant differences (P ＜ 0.05).Conclusion Combined with hypoglycemic treatment,atorvastatin may delay the progress of carotid atherosclerosis and improve the endothelial function in elderly patients with T2DM.

Objective To realize the safe work of hospital network and ensure the veracity and reliability of the hospital information system (HIS). Methods The network malfunctions and cause of HIS since from its beginning were analyzed by making full use of statistical graph and summarized the factors of affecting HIS safety. The safety complications of HIS were rebuilt by using collecting cluster server, double-redundant design of switchboard, the installation of firewall, installing anti -virus software,etc. The strict safety regulations were established and operation levels of technical personnel were enhanced. Results The hospital runs smoothly, no major network malfunction comes to true repeatedly. Conclusion The HIS safety is realized by attaching importance to the safety and strengthening the input.

Objective To investigate whether switching anti-hypertensive medication to bedtime could improve blood pressure control in non-dipper patients with refractory arterial hypertension.Methods 30 patients (as observation group) with refractory arterial hypertension and non-dipper pattern on ambulatory blood pressure monitoring were shifted all non-diuretic anti-hypertensive drugs from morning to evening.22 patients with similar characteristics and no changes in the therapeutic regimen formed the control group.Results After 12 weeks treatment,the changes of 24h average systolic/diastolic blood pressure,average diastolic blood pressure during the day and the average diastolic blood pressure at day/nigh were-(2.8 ± 4.2)/-(2.1 ± 3.4)mm Hg,(-1.1 ± 3.1)mm Hg and (-6.3 ±5.9)/(-4.3 ±5.7)mm Hg,respectively.The decrease of mean systolic blood pressure and mean diastolic blood pressure in the observation group were significantly larger than those in the control group(all P ＜0.05).The circadian blood pressure profile changed from non-dipper to dipper in 6 cases in the observation group and no changes were observed in the control group(x2 =4.974,P =0.0263).There was also no difference between two group in terms of untoward reaction.Conclusion In non-dipper patients with refractory arterial hypertension,changing the timing of anti-hypertensive medication to the evening could improve blood pressure control aud help the abnormal circadian blood pressure profile recover to the normal.

Signaling pathways such as MAPK and P13K have been confirmed to be important in the mechanism of tumor genesis, development, prevention and treatment. Thyroid hormone (TH) and its receptor (TR) can affect the pathways resulting in inhibition of tumor growth and metastasis, thus they have gradually become the focus of recent research. However, numerous studies showed that TR gene mutation was often observed in a variety of cancers and resulted in the deregulation of TH/TR mediated downstream pathways, and TR gene mutation became an causative agent to activate downstream proto-oncogene. Recent studies showed that TH/TR might play a role in the regulation of β-catenin degradation, the knowledge of which allows us not only to further understand the function of TR gene in the inhibition of tumor development, but also provide a theoretical basis for the continuous activation of downstream proto-oncogene by TR mutation. To study the downstream pathway of TR gene could eventually guide the clinician and provide a new theoretical basis for cancer prevention and molecular target gene therapy.

Objective To analyse the economies of scale in public hospitals in Zhejiang Province. Methods One hundred and twenty-five public hospitals in Zhejiang Province with qualification no less than class two level two were selected as sample hospitals. Douglas production function was employed to analyse the relationship between investment and output in sample hospitals between 2004 to 2006, with two types of production models established by medical service and incomes in hospitals as dependent variables. Results From 2004 to 2006, the medical service and incomes of sample hospitals were in line with economies of scale. The production increase rate was higher than investment increase rate. The medical service, incomes, total assets and number of staff in class three hospitals were higher than those in class two hospitals (P =0.000). Conclusion Economies of scale is the ultimate incentive to continuous outstretch for hospitals. Hospitals should rationally control the scale so as to avoid problems in medical service caused by overstretch.

Objective:To analyze and discuss the factors of seizure induced by imipenem/cilastatin.Method: The reports of seizure induced by imipenem/cilastatin from CBMDisc(1971-2006)and CHKD(1994-2006)were re- viewed and analyzed with Excel.Result:28 cases of seizure induced by imipenem/cilastatin were collected,including 20 men and 8 women with the principal primary respiratory infection with an average age of 66.5.Seizure occurred as early as 10 min.after the medication,and occurred latest in the fourth day of the medication.22 cases showed grand mal seizure and 6,partial seizure with a duration ranging from 20s to 30min and with a frequency of eight seizures.18 cases discontin- ued the administration,and 8 cases took lower daily dosage,in which some were given antiepileptic drugs or other adjunc- tive therapy,and 2 cases were not treated at all.All the cases recovered and were discharged from hospital except one who died from his circulation failure and respiration failure.The cause-effect relations of the relevance evaluation of seizures e- yoked by imipenem/cilastatin were as follows:1 sure case,26 probable cases,and 1 possible case.Conclusion:Seizure can be induced by imipenem/cilastatin,Owhich should be rationally used.More attention should be paid in clinic so as to ensure a safe medication.
