Objective To investigate the risk factors for cardiovascular complications in the elderly persons undergone with dialysis.Methods One hundred and eighteen patients undergone with hemodialysis(HD)or continuous ambulatory peritoneal dialysis(CAPD)at the Eastern Hospital, Tongji University, Shanghai during January 2002 to December 2006 were retrospectively analyzed.They were divided into four groups based oil their age and mode of dialysis, i.e., 44 patients in the elderly HD group(aged over 60years), 16 patients in the elderly CAPD group(aged over 60), 46 patients in medium-age HD group(aged under 60 years)and 12 patients in the medium-age CAPD group(aged under 60).Routine biochemical parameters were measured for all the patients and their difference was compared among the four groups.Logistic regression analysis was performed for the risk factors of cardiovascular complications.Results Pulse pressure(PP)was(66±21)mm Hg, serum level of triglycerides(TG)was(1.28±0.67)mmol/L, serum level of lipoprotein(a)[LP(a)]was(434±202)mg/L, C-reactive protein was(CRP)(21±15)mg/L, serum phosphorous(P3-)was(2.02±0.77)mmol/L, and product of serum calcium and phosphorous(Ca×P)was(4.3±1.6)mmol2/L2, respectively, in the elderly group with dialysis, all significantly higher than those in the medium-age group with dialysis(t=1.535, 1.016, 2.154, 2.252, 4.676, and 4.534, respectively, P＜0.05).Incidence of cardiovascular events was markedly lower in the CAPD group than that in the HD group(P＜0.05), either in the elderly or medium-aged patients.And, incidence of cardiovascular complications correlated positively with age, PP, LP(a), CRP and Ca×P of the patients with dialysis, but correlated reversely with serum level of albumin(all with P＜0.05).Conclusions There exist a few risk factors for cardiovascular complications in the elderly patients with dialysis, so proper mode of dialysis should be selected for those who need it and adequate intervention should be implemented for them to correct the risk factors.

Objective To investigate the interaction between NMDA receptor subunit 2B (NR2B) and metabotropic glutamate receptor 5 (mGluR5) in the spinal cord of morphine-tolerant rats. Methods Sixteen male SD rats weighing 220-280 g were randomly divided into 2 groups with 8 rats in each group: control group (C) and morphine group (M). In group M morphine 10μg was administered intrathecally (IT) twice a day for 7 consecutive days. In group C equal volume of normal saline was given instead of morphine. Tail flick latency (TFL) (a segment of tail 4-5 cm long was immersed in 52-53℃ hot water) was used to measure the antinocicepitve effect of morphine before and 30 min after morphine administration every morning. MPE (percentage of maximal possible effect) was calculated (pain threshold after drug administration - baseline pain threshold)/(10- baseline pain threshold)× 100% . The animals were killed at the next day after last IT administration and the dorsal half of L4-5 spinal cord was isolated and homogenized for determination of NR2B and mGluR5 protein expression by Western blot and CO-IP. Results MPE was significantly increased at 1-5 d of drug administration and returned to baseline at 7 d in group M as compared with group C. The mGluR5 protein expression was significantly up-regulated in group M as compared with group C but there was no significant difference in NR2B protein expression between the 2 groups. Conclusion There is interaction between NK2B and mGluR5 in the spinal cord of morphine-tolerant rats.

Objective:Discuss how the management of implantable medical consumables can be standard during the links of production, transportation, internal logistics of the hospital and the sector of using. Methods: In accordance with the relevant national laws and regulations, and long-term management practice and experience, and aiming at the specialty and high risk characteristics of implanting medical consumables, we apply information technique to regulate the standard operation of the whole medical supplies links (raw materials, processing of products, marketing, warehousing transportation, and the usage of the patients), therefore the roots can be traced back. The implanted medical supplies traceability standardized management needs to be explored. Results: Through the establishment of the traceability management process system of implanting medical supplies, the standard management mode of the medical supply technique will be attained. Even when the information is incomplete, we can retrieve and trace back quickly. Therefore, the goal of controlling the adverse events of medical implants, reducing medical risks can be achieved. Conclusion:the discussion above can be taken as a reference to the standardization of the management of implantable medical consumables.

Methods: Acute viral myocarditis was induced in 24 Balb/c mice by injection of Coxsackievirus B 3m (CVB 3m ) intraperitoneally. Half of the mice were administered Astragalus Injection(10g/kg?d). Heart and blood samples were obtained from all mice on the 8th day after CVB 3m infection for histopathological study, detection of myocardial perforin expression by reverse transcription polymerase chain reacton(RT PCR) and measurement of serum CK MB level, respectively. Results: (1) Astragalus treated mice showed a significant reduction in myocardial lesion compared with that in untreated mice. (2) Myocardial perforin expression by semi quantitative RT PCR in Astragalus treated mice was much lower than that in controls(1.10?0.07 vs 1.31?0.12, P
