肝硬化病人门静脉和肝动脉多谱勒血流参数变化的意义

目的 :探讨肝硬化门脉高压病人门静脉和肝动脉彩色多谱勒血流参数变化的意义。方法 :肝硬化伴食道静脉曲张的病人 6 6例 ,正常人对照组 5 8例。测量门静脉血流速度 (PVV)和肝动脉阻力参数 (HA- PI) ,计算肝血管指数。结果 :在肝硬化门脉高压病人比对照组 PVV明显降低 (12± 2 .2 ) cm/ s;(15 .8± 2 .6 ) cm/ s,P<0 .0 0 1)和 HA- PI明显增高(1.3± 0 .15 ;0 .94± 0 .16 ,P<0 .0 0 1) ,肝血管指数明显减低 [(8.6± 2 .1) cm/ s;(16 .7± 4 .2 ) cm / s,P<0 .0 0 1) ]。彩色多谱勒血流参数 PVV、HA- PI、肝血管指数对肝硬化门脉高压的诊断的敏感性和特异性分别为 89%、84 %、83%、81%、95%、91%。结论 :肝血管指数对肝硬化门脉高压的诊断的敏感性和特异性更高。     

Transplant aspirative cytology: Analysis of morphological and immunocytochemical parameters in renal allograft dysfunction

We have analyzed 245 transplant aspirative cytologies (TACs) from 96 renal allograft patients. TACs were divided in two chronological groups: Early (TACs performed during the first 3-mo post-transplantation) and late (TACs performed after the third month post-transplantation), in order to assess the effect of allograft tolerance on TAC features. Both morphological and immunocytochemical aspects were evaluated, including CD4, CD8, IL2-R, and HLA-DR immunolabeling. A final diagnosis for each case of allograft dysfunction was achieved by other independent diagnostic means. Four diagnostic groups were considered in the present study: acute rejection (AR), chronic rejection (CR), acute tubular necrosis (ATN), and Cyclosporin A toxicity (CsA-T). In addition, a control group (C) was established from patients with stable allograft function. We found that immunocytochemical analysis of TACs is particularly helpful in the diagnosis of late allograft dysfunction, a time period when the simple cytological study of renal infiltrate is not informative enough to help take therapeutic decisions.

Evaluation of biochemical variables in patients with trigeminal neuralgia

The aim of this study was to evaluate the calcium, sodium, potassium, serum iron, vitamin B12, and albumin concentrations, and alkaline phosphatase (ALP) activity, in samples of serum from patients with primary trigeminal neuralgia (TN), and investigate the associations between them. Results from 73 patients who had been diagnosed with primary TN between December 2015 and 2017 were compared with those of 70 healthy subjects. Calcium (p = 0.013), iron (p = 0.004), and albumin (p = 0.001) concentrations in the primary TN group were significantly lower than those in the control group, whereas the ALP activity was significantly higher in the TN group than in the control group (p = 0.007). However, there was no significant difference in the sodium, potassium, or vitamin B12 concentrations. Biochemical variables have a role in the pathogenesis and treatment of primary TN, but there are few studies that characterise the relations between the condition and the biochemical changes. Further studies are therefore necessary to gain more information.     

高血压病患者血压各参数与其并发脑卒中的关系

目的探讨高血压病患者血压各参数与其发生脑卒中的关系。方法回顾性分析798例高血压病患者。年龄45．65岁,其中单纯高血压病患者400例,高血压并发脑卒中者398例,分析两组患者的血压各参数关系,探讨收缩压、舒张压、平均血压、脉压与高血压并发脑卒中的相关性。结果收缩压、平均血压、脉压：脑卒中组与单纯高血压组比较有显著性差异（P〈0．05,P〈0．01）;舒张压：脑卒中组与单纯高血压组比较无显著性差异（P〉0．05）。结论中老年高血压病患者,收缩压、平均血压、脉压与脑卒中的发生有显著相关性,舒张压与脑卒中的发生无显著相关性。
