对50例MOF患儿血糖血乳酸血渗透压进行了检测,并与35名健康儿童进行比较。结果显示危重患儿血糖血乳酸明显高于对照组,血糖血乳酸呈正相关,提示高血糖是危重患儿应激状态下的主要代谢改变。当患儿血糖>15mmol/L血乳酸)5mmol/L时,其死亡率明显增加,因此血糖血乳酸的变化可作为PICU的常规监测指标。 相似文献

瘦素、胆囊收缩素、血脂与胆石类型关系探讨 总被引:5,自引:0,他引:5
目的探讨瘦素(leptin)、缩胆囊肽(CCK)、血脂、胆固醇与Gs和HS两类胆石病关系。方法比较检测339例胆囊结石(Gs),67例肝胆管结石(HS)病员,20例正常对照者血清leptin、CCK、胰岛素、肝功能、血脂、脂蛋白等,评价各检测指标间关系。结果GS组leptin、CCK、BMI、胆固醇、甘油三酯、白蛋白、GGT、APO-a显著高于HS组(P〈0.05);GS组内leptin与CCK、BMI、胰岛素、转氨酶、胆红素、胆固醇呈正相关(P〈0.05);HS组内leptin与CCK、BMI、胰岛素、转氨酶、胆红素呈正相关(P〈0.01),与白蛋白、APO-a呈负相关(P〈0.05)。结论Leptin参与调控脂质代谢,两类胆石Leptin、血脂等存在明显差别,从调控脂质代谢角度探讨Leptin在两类胆石中的作用可能对阐明胆石成因具有价值。 相似文献

A cohort study was undertaken to compare the effect at the timeof oocyte retrieval of the i.v. administration of either 1000ml of lactated Ringer' solution or 1000 ml of a 5% solutionof human albumin on in-vitro fertilization patients at riskfor severe ovarian hyperstimulation syndrome (OHSS). A totalof 207 patients with an oestradiol concentration > 10 000pmol/l and/or > 15 follicles (>10 mm diameter) on theday of human chorionic gonadotrophin (HCG) injection were reviewed.Of these, 158 women received 500 ml of lactated Ringerssolution both before and after egg retrieval, and 49 women receivedtwo infusions of 500 ml of 5% human albumin in normal salineat the time of egg retrieval. Severe OHSS developed in two patientswho received human albumin and in 10 women who did not receivethe albumin. This difference was not statistically significant.There were no differences between the two groups in terms ofage, number of follicles punctured at transvaginal oocyte retrievalor oestradiol concentration at the time of HCG injection. Theadministration of a 5% human albumin solution does not preventthe development of severe OHSS in at risk patients. It doesappear to blunt the severity of the condition. 相似文献

Whereas many foreign proteins are immunogenic, only a proportion is also allergenic, having the capacity to induce the quality of immune response necessary to support the production of IgE antibody. We have demonstrated previously that intraperitoneal administration to mice of proteins such as ovalbumin (OVA) or the industrial enzyme A. oryzae lipase, which possess significant allergenic potential, stimulates the production of both IgG and IgE antibody. Identical exposure to bovine serum albumin (BSA), a protein with limited potential to cause immediate respiratory or gastrointestinal hypersensitivity reactions, induced IgG responses only. In the current investigations, the quality of immune responses induced following exposure to these proteins via mucosal tissue (intranasal) has been compared with those provoked following administration via a non-mucosal (intraperitoneal) route of exposure. Intranasal or intraperitoneal administration of BSA, OVA or A. oryzae lipase elicited in each case vigorous IgG and IgG1 antibody responses. For all three proteins, at every concentration tested, and via both routes of exposure, IgG1 antibody titres paralleled closely IgG titres. However, the three materials displayed a differential potential to provoke IgE responses and this correlated with their known allergenic potential in humans. Thus, OVA and A. oryzae lipase stimulated strong IgE antibody responses, whereas BSA provoked low titre IgE only at the highest concentration tested (5% administered intraperitoneally). The quality of induced responses was not affected by the route of exposure. It would appear, therefore, that the stimulation of IgG and IgG1 antibody responses is a reflection of protein immunogenicity whereas protein allergenicity is associated with the induction of strong IgE responses. 相似文献

Abstract: Adequate venous access is an essential component of therapeutic plasma exchange (TPEX). The simplest kind of venous access is venipuncture of antecubital veins, but this technique may be limited by venous size or scarring following the procedure, requiring the placement of a specialized vascular access device (VAD). VADs provide reliable central venous access and may remain in place for several weeks or months, depending on the VAD and the venous site chosen. Their use, however, is potentially limited by the risk of complications. We discuss indications for insertion, choice of catheter and access site, and complications of VAD placement for TPEX. 相似文献
