Journal of Shanghai Jiaotong University(Medical Science) 2006;0(06):-
Objective To quantitatively compare the effects of bleach and peracetic acid reprocessing on the clearance and surface charge characteristics of Fresenius F80B polysulfone dialyzers. Methods Clearance experiments were performed using urea, vitamin B_12, and polydisperse dextrans in an in vitro dialysis circuit. Clearance, ultrafiltration coefficient and zeta potential were obtained on a new F80B dialyzer, after exposure to plasma in a 3 h in vitro dialysis session, and after cleaning with bleach and peracetic acid.Results Bleach was able to remove the protein deposit, restoring the clearance characteristics, but there was a significant increase in the net negative charge of the membrane due to chemical reaction with the bleach. In addition, longer time exposure to bleach altered the membrane transport characteristics, increasing the solute clearance. Dialyzers cleaned with peracetic acid had significantly lower clearance of the larger dextrans due to the presence of residual protein on or within the membrane. Conclusion Cleaning with bleach and peracetic acid may have dramatically different effects on the clearance and surface charge characteristics of F80B polysulfone dialyzers.

Objective To evaluate the role of bispectral index (BIS) in assessing the depth of sedation in hypogastric operation of children. Methods Forty children undergoing hypogastric operation were divided into two groups with 20 cases each by pre-school (age 3-5) (Ⅰ group) and school (age 6-12)(Ⅱ group). Sedation was solely maintained with TCI propofol. The infusion was adjusted till adequate scdation (OAA/S≤ 1 score) before sacral block. The course of propofol infusion and BIS of recovery period were closely observed. Sedation scores were assessed by special anesthetists. Results During recovery period, the mean values of BIS were gradually increased, when BIS > 76 predicted 94% sensitivity and 50% specificity in Ⅰ group, 100% sensitivity and 100% specificity in Ⅱ group. ROC area under the curve of the two groups were 0.917 ± 0.007, 0.955 ± 0.004. Conclusions BIS can predict fairly well the level of consciences during recovering periods. BIS monitoring is an effective and reliable method to guide children recovery.

BACKGROUND:Traditional Chinese medicine plays a specific role in the clinical diagnosis and treatment of ischemia reperfusion injury. OBJECTIVE:To investigate the effect of Bu Yang Huan Wu Decoction on ischemia reperfusion injury in rats after replantation of of lower limbs, and evaluate the protective effect and mechanism of ischemic tissue. METHODS:A total of 120 Wistar rats were randomly divided into four groups:normal control (intragastric administration of saline after anesthesia), Bu Yang Huan Wu Decoction (intragastric administration of 10 mL/kg Bu Yang Huan Wu Decoction immediately after reperfusion), edaravone (intravenous administration of 10 mL/kg edaravone immediately after reperfusion), and blank control (intragastric administration of saline) groups. At 24 hours after reperfusion, the myeloperoxidase, lactate dehydrogenase, nitricoxide synthase, inducible nitricoxide synthase, constitutive nitricoxide synthase level in the blood were detected. At 1 week after reperfusion, the activity of superoxide dismutase in gastrocnemius tissue, nitrogen monoxidum and malondialdehyde, and the load of Ca2+were assayed. RT-PCR semiquantitative analysis was performed to detect bcl-2 mRNA and bax mRNA transcriptional levels in the gastrocnemius.RESULTS AND CONCLUSION:Bu Yang Huan Wu Decoction protected the rats from ischemia reperfusion injury by reducing the production of oxygen free radicals, reinforcing the activity of superoxide dismutase, lessening the calcium overload, decreasing the production of nitrogen monoxidum, up-regulating the expression of anti-apoptotic gene bcl-2, down-regulating the expression of pro-apoptotic gene bax, and attenuating the injury of skeletal muscle after ischemia reperfusion injury. Bu Yang Huan Wu Decoction has significant protection on cerebral ischemia reperfusion injury in rats after replantation of severed limb, which may be related to the scavenge of free radicals, inhibition of skeletal cells apoptosis, and attenuation of reperfusion injury.

Objective To explore hypoxemia on transportation in elderly patients who underwent laparoscopic cholecystectomy(LC) under general anesthesia. Methods SPO 2 was monitered continuously during peridecannulation period, especially within the first 5 minutes in case of incidence of hypoxemia. Results 15 out of 100 cases were found to undergo hypoxemia with SPO 2≤92%. The incidence rate of hypoxemia was 15%(15/100). Conclusions It is important to monitor SPO 2 and administer oxygen inhalation continuously on transfer from operation room back to ward to prevent hypoxemia in elderly patients.

Objective To investigate the correlation of blood lipid metabolism abnormity and other components of metabolic syndrome on angiocardiopathy and cerebrovascular diseases in the elderly people. Methods The clinical data of elderly people, who underwent medical examination during 1996 to 2005 in the General Hospital of PLA, were retrospectively analyzed. Based on the analysis, the co-existence of blood lipid disorders with glucose metabolic abnormity, hypertension and obesity, as well as their influence on cardio-cerebrovascular diseases were further analyzed. Results The prevalence of blood lipid metabolic disturbance was 69.6%, in which the prevalence of hyper-cholesteremia and hyper-triglyceride were 23.6% and 21.7%, respectively. The prevalence of hyper-cholesteremia accompanied by hyper-triglyceride (mixed group) was 19.3%, that of hyper-triglyceride with lower high density lipoprotein cholesterol was 5.03%, while it was 30.4% in the normal group. There was a higher risk of having the above abnormal condition in patients with type 2 diabetes mellitus (T2DM) and obesity, and they were more frequently complicated by hypertension in the hyper-triglyceride group (70.8%). When the patients with lipid metabolic disturbance were complicated by T2DM, hypertension and obesity, the prevalence of cardiovascular or cerebrovascular diseases increased. The prevalence of CHD was higher in the patients with hyper-cholesteremia and hypertension or diabetes, and incidence of both CHD and CVD was higher in the patients with hyper-triglyceride and either one of hypertension, diabetes or obesity. Conclusion There is high prevalence of lipid metabolic disturbance (more than two thirds) and other components of metabolic syndrome, and high risk of suffering from cardiovascular or cerebrovascular diseases in elderly people. The aging patients with hyper-triglyceride are vulnerable to cardiovascular or cerebrovascular diseases, and more attention should be paid in clinical practice in future.
