Background
To investigate the potential mechanisms of hypothermic machine perfusion (HMP)'s beneficial effects on kidney graft over static cold storage (SCS) in vitro.Methods
Ten kidneys of 5 Bama miniature male pigs were paired into 2 groups: SCS group and HMP group. Preservation solutions were taken at 0, 1, 3, and 6 hours for the measurement of K+, Na+, Cl?, blood urea nitrogen (BUN), creatinine (Cr), and lactate dehydrogenase (LDH) using the standard laboratory methods. Renal cortex were harvested at 6 hours for the following measurement: lactic acid (LD), adenosine triphosphate (ATP), malondialdehyde (MDA), neutrophil accumulation (MPO), interleukin-10 (IL-10), and transforming growth factor-β (TGF-β). Ischemia-induced apoptosis and the protein expression levels of total Akt, phospho-Akt, total Erk, and phospho-Erk were analyzed by Western blotting.Results
Almost all of the tested metabolites in preservation solutions were reduced with time in the HMP group. Levels of Na+, Cl?, BUN, Cr, K+, and LDH were lower in the HMP group compared with the SCS group, with differences in the first 4 reaching statistical significance. HMP alleviated ATP degradation and LD accumulation, diminished the MDA (P < .05) and MPO (P = .227) levels, and greatly raised IL-10 and TGF-β (P < .05) expression. A marked decrease of proapoptotic and a large increase of antiapoptotic markers (P < .05) along with greatly raised Akt (P < .05) and Erk (P < .01) phosphorylation was observed in the kidney of the HMP group compared with the SCS group.Conclusion
HMP's kidney graft protection involves inhibition of accumulation of toxic metabolites, oxidative damage, and apoptosis along with upregulation of the Akt and Erk signaling pathway. 相似文献53.
目的:研究郑启仲教授运用升降散用药规律。方法:通过收集郑启仲教授门诊处方,录入中医传承辅助平台,使用软件的统计报表模块、数据分析模块和关联规则apriori算法等数据挖掘方法,分析处方中药物应用频次、药物组合频次等,并进行关联规则分析,重点分析发热和咳嗽为主症的用药规律,研究郑启仲教授运用升降散用药规律。结果:应用关联规则分析发现升降散常与柴胡、黄芩、生石膏、甘草等配伍。发热为主症的疾病常用处方:升降散、普济消毒饮、银翘散等,多与生石膏、栀子、浙贝母、羚羊角等药物配伍。咳嗽为主症的疾病常用处方:升降散、麻杏石甘汤、三拗汤、小柴胡汤等,多与川贝母、莱菔子、连翘、栀子、葶苈子、羚羊角等配伍。结论:郑启仲教授灵活运用升降散治疗儿科外感温病及内伤杂病,擅用升清降浊治法,组方用药体现了升清降浊的治疗思想。 相似文献

BackgroundThere is an urgent need to develop a convenient and less invasive technique to monitor the efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) in patients with EGFR-mutated non–small-cell lung cancer (NSCLC). We proposed folate receptor–based assay to count circulating tumor cells (CTCs) to predict and dynamically monitor the therapeutic response to first-line EGFR-TKIs in patients with EGFR-mutated NSCLC.Patients and MethodsEligible patients were enrolled, and 3 mL of blood was obtained before initial treatment, 1 month after treatment, and every 2 months thereafter. CTCs were isolated on the basis of negative enrichment by immunomagnetic beads and detected by a ligand-targeted PCR method.ResultsA total of 232 patients with EGFR-mutated NSCLC and treated with first-line EGFR-TKIs were included. Patients with low baseline CTC count had a markedly longer progression-free survival (hazard ratio = 0.48; P < .001) and overall survival (hazard ratio = 0.52; P = .002) than those with high count. This difference remained significant in multivariate analysis. Dynamic change of CTC count was significantly associated with partial response (P = .042) and stable disease/progressive disease (P = .032). Notably, dynamic monitoring of CTC provided evidence of resistance to EGFR-TKIs before computed tomographic scanning with a median lead time of 113 days (range, 45-169 days).ConclusionThe current evidence suggests that folate receptor–positive CTC counts can be used for both the dynamic monitoring and prediction of outcome in EGFR-mutated NSCLC patients treated with EGFR-TKIs, which could serve as an alternative or supplement to computed tomographic scanning. 相似文献

《伤寒论》是一部以讨论外感病为主而阐发运用辨证论治方法的著作,书中仲景既示人以规矩,又诲人以技巧。其言精奥,其法简详,其中第101条:"伤寒中风,有柴胡证,但见一证便是,不必悉具。"后世医家或伤寒论注家对此"一证"争论不休、莫衷一是,对此笔者认为此"一证"定是"主证",其义有二:一为某方所治之证侯;二即某证侯中之主要症状。 相似文献
