青年男性湿热环境运动中核心温度的预测

摘要：目的：观察青年男性在湿热环境运动中心率（HR）、心率变异性（HRV）、核心温度（Tc）、额温（Tf）的变化,探讨并建立青年男性湿热环境运动中Tc的预测公式。方法：选取非体育专业大学生21名,在温度36.0 °C、相对湿度60.0%的环境下完成运动平板实验,初始以40%~50%VO2max的强度（≈6.4 km/h的速度）运动20 min,而后增加强度至60%VO2max左右的强度（≈9.6 km/h的速度）运动至力竭。在运动过程中实时监测受试者的HR、HRV、Tc、Tf,并在运动前后对受试者的体重进行测量。结果：受试者在运动29.7±3.8 min后达到力竭,力竭时刻HR达到201±10 beats/min; Tc达到39.1±0.3 °C;Tf到达39.6±0.7 °C;体重丢失达到590±512 g。运动过程中HR、Tc、Tf显著升高（P<0.05）,HRV的时域指标STD、RMSSD、RRindex显著下降（P<0.05）。经回归分析显示,HR为良好的Tc预测指标,预测公式为Tc =39.17-0.02HR-4HR2（r2=0.969;P=0.001）或Tc =0.02HR+34.66（r2=0.977;P=0.000 6）。此外,还发现HR是预测5 min后Tf值的良好指标（r2=0.974;P=0.006）。结论：青年男性在湿热环境下进行先低等强度后中等强度的运动时,可以运用HR对机体的Tc进行预测,以预防热疾病的发生。     

《西游记》中的观音“疥癞”形象源流考

《西游记》第八回中观音为寻取经人,幻化模样后的人间形象是一个满身病疮的,衣衫褴褛的落魄和尚。在人们心目中法相庄严的观音怎么会幻化成这样一副模样？这绝不是信手拈来的自由发挥,而是有着文献依据的。通过一连串相互继连的记载可以考证出其源流。     

阿尔茨海默病发病机理的研究进展

阿尔茨海默病(Alzheimer’s disease,AD)病因及发病机制尚未完全阐明,有关其发病机制有β-淀粉样蛋白假说、Tau 蛋白假说、炎症学说和氧化应激学说等多种.本文就现有较公认的发病机制研究进展作一综述.     

A case study of imported pulmonary coccidioidomycosis

Coccidioidomycosis is an endemic disease of the Western hemisphere. The cases in non-endemic areas are mostly imported. Determining a history of exposure is critical for performing the diagnosis of coccidioidomycosis, especially for cases occurring in a non-endemic area. In this study, a 71-year-old Chinese male presented to our hospital with chronic cough and malaise, and was found to have a mass in the middle lobe of right lung. He had been visiting Arizona, USA for four months before admission. Pulmonary coccidioidomycosis was confirmed by the results of histopathological examination after lobectomy. Typical microscopic features of Coccidioides are definitely diagnostic, but need be differentiated from other budding yeast infection or carcinoma histopathologically.     

景物描写应伴随心灵的颤动

当前学生作文最突出的1部,是缺乏生活气息,缺乏生活的留心和观察,缺乏对生活独到的感受,这一点在学生作文——写景的片段中表现得最为明显。写景不是孤立的,它常常同写人叙事,抒情结合在一起,创造环境气氛,烘托人物性格,推动情节发展。若要达到这个目的,前提即做一个生活的有心人。     

李贽琴乐思想探赜

晚明思想家、文学家李贽在其著作《焚书?琴赋》中提出了“琴者心也”的观点,这一命题对晚明及其后的琴乐发展产生了深远影响。许多学者认为这是对儒家礼乐思想的反叛。然而,深层挖掘“琴者心也”之“心”的思想内涵并梳理历代琴论,可以发现,李贽此说并非空谷之音。“琴者心也”是顺着主流琴乐思想之外的注重古琴自身艺术特性的琴乐思想发展而来的,这种思想并非离经叛道,而是一种对僵化的琴论的内在批判,以引导琴论健康发展。     

《大乘起信论》之“众生心”阐析

“众生心”是《大乘起信论》的重要概念,它能开显出“心真如”和“心生灭”二门,一心开二门架构中的一心就是众生心。众生心开显出二门,二门不相离,却又不等同,心真如是真实的存在,心生灭却是幻化的现象。心真如虽是佛法之根本,然而真如本性的示现,却必须以心生灭所产生的染法为中介,才能被愚痴众生所明白,也就是所谓的真如并不存在于生灭之外。众生心的真如门使凡人求佛有了实现的可能性,生灭门则为人们认识佛法提供了必要条件,从而使大乘佛法得以全部地显现。因此,只有对众生心加以全面地阐析,才能了解大乘佛法的真谛。     

新冠肺炎疫情对我国上市港航及船舶制造企业财务状况的影响

为量化新冠肺炎疫情对我国水路运输企业财务状况的影响,本文基于Z score模型对构成水路运输产业链核心的港口、航运、船舶制造三类上市企业财务状况进行评价。通过对比疫情发生前后企业财务状况的变化,明确疫情在不同时期对水路运输企业财务状况的影响,以及对不同类企业带来的异质化影响。研究结果表明,在疫情发生初期我国水路运输业受到短期负面冲击较大,企业经营利润均出现明显下降,其中港口和船舶制造企业财务状况恶化较为显著,而航运企业财务状况受影响较小。随着国内疫情得到有效控制,水路运输业整体经营状况逐渐向好,特别是船舶制造企业得益于船舶订单量的增长,财务状况改善较为明显。港口企业恢复则较为疲软,且不同港口企业间的分化有所加剧。航运企业总体财务状况相对较为稳健。     

Biochemical Evaluation of Patients of Alcoholic Liver Disease and Non-alcoholic Liver Disease

Alcoholic liver disease (ALD) is due to excessive alcohol intake for long duration. Distinguishing ALD from non-ALD (non-alcoholic steatohepatitis, hepatitis of viral origin) is difficult as patient may deny alcohol abuse. Clinical examination, histology and serology may not differentiate these conditions. Accurate diagnosis is important as management of ALD differs from non-ALD patients. The aim of our study was (1) To evaluate the patients of ALD and non-ALD by biochemical parameters compared to controls, (2) To assess whether these parameters can differentiate ALD from non-ALD. Study was carried out on 50 patients of ALD in group I and 35 patients of NASH (non-alcoholic steatohepatitis) and acute viral hepatitis each in group II. Age matched healthy controls n = 50. Selection criteria—history of alcohol intake (amount and duration), clinical examination, sonography of abdomen, serum alanine transaminase (ALT) and bilirubin levels. Blood samples were analyzed for bilirubin, aspartate transaminase (AST), ALT, alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) by kinetic method. Statistical analysis was done by Student unpaired ‘t’ test. Patients of ALD have raised AST/ALT ratio (De Ritis ratio) (>2), ALP and GGT compared to controls (P < 0.01).There is significant difference in AST/ALT ratio, serum GGT and ALP in ALD group compared to that in NASH and acute viral hepatitis (P < 0.05). This study suggests that De Ritis ratio >2 in ALD patients may be due to alcohol induced hepatic mitochondrial injury and pyridoxine deficiency. High GGT and ALP values may indicate enzyme induction by alcohol and mild cholestasis. Thus ALD patients have severe hepatic damage. De Ritis ratio <1 and normal to mild elevation in GGT level in NASH and acute viral hepatitis suggest mild hepatic injury of non-alcoholic origin. Our study concludes that ALD patients can be differentiated from NASH and acute viral hepatitis with certainty by measuring serum AST/ALT ratio, GGT and ALP. These biochemical parameters may help clinicians to support the diagnosis of ALD and non-ALD.
