目的探讨乙肝相关性肝癌临床病理学特征与溶血磷脂酸(LPA)和高敏C反应蛋白(hs-CRP)表达的相关性。方法选取2019年1月至2020年1月间河南省驻马店市中心医院收治的198例乙肝相关性肝癌患者作为乙肝组,198例酒精相关性肝癌患者作为酒精组。两组患者都进行血清hs-CRP和LPA表达检测,调查患者的病理学特征并进行相关性分析。结果乙肝组患者血清hs-CRP和LPA含量均高于酒精组,差异均有统计学意义(均P <0.05)。两组患者血清ALP、AFP、ALT、AST和GGT含量比较,差异均无统计学意义(P> 0.05)。乙肝组不同临床分期和组织学分化患者的血清hs-CRP和LPA含量比较,差异均有统计学意义(均P <0.05)。乙肝组患者的临床分期和组织学分化与血清hs-CRP和LPA表达均存在相关性,差异均有统计学意义(均P <0.05)。患者的临床分期和组织学分化均为影响hs-CRP和LPA表达的重要因素,差异均有统计学意义(均P <0.05)。结论相对于酒精相关性肝癌,乙肝相关性肝癌的血清hs-CRP和LPA呈现高表达,与患者的临床病理学特征存在相关性。 相似文献

In the field of drug development, technology for producing human metabolites at a low cost is required. In this study, we explored the possibility of using prokaryotic water-soluble cytochrome P450 (CYP) to produce human metabolites. Streptomyces griseolus CYP105A1 metabolizes various non-steroidal anti-inflammatory drugs (NSAIDs), including diclofenac, mefenamic acid, flufenamic acid, tolfenamic acid, meclofenamic acid, and ibuprofen. CYP105A1 showed 4′-hydroxylation activity towards diclofenac, mefenamic acid, flufenamic acid, tolfenamic acid, and meclofenamic acid. It should be noted that this reaction specificity was similar to that of human CYP2C9. In the case of mefenamic acid, another metabolite, 3′-hydroxymethyl mefenamic acid, was detected as a major metabolite. Substitution of Arg at position 73 with Ala in CYP105A1 dramatically reduced the hydroxylation activity toward diclofenac, flufenamic acid, and ibuprofen, indicating that Arg73 is essential for the hydroxylation of these substrates. In contrast, substitution of Arg84 with Ala remarkably increased the hydroxylation activity towards diclofenac, mefenamic acid, and flufenamic acid. Recombinant Rhodococcus erythrocyte cells expressing the CYP105A1 variant R84A/M239A showed complete conversion of diclofenac into 4′-hydroxydiclofenac. These results suggest the usefulness of recombinant R. erythropolis cells expressing actinomycete CYP, such as CYP105A1, for the production of human drug metabolites. 相似文献

目的探讨维持性血液透析(MHD)患者血清维生素D水平对下肢肌力减退的预测作用。 方法横断面研究设计,选择2018年9月至10月于战略支援部队特色医学中心血液净化中心的95例MHD患者,检测其血清25-羟维生素D3[25(OH)D3]水平,采用5次站立-坐下实验(5-STS)评价其下肢肌力。根据5-STS完成时间将MHD患者分为下肢肌力正常组(n=85)与减退组(n=10),比较两组患者人口学特征、实验室指标。采用多因素Logistic回归分析下肢肌力减退的影响因素,绘制受试者工作特征(ROC)曲线分析上述因素预测MHD患者发生下肢肌力减退的特异度和敏感度。 结果95例MHD患者血清25(OH)D3水平为11.00~99.50 nmol/L,中位数31.23(19.90~43.30)nmol/L;5-STS完成时间为3.55 s~18.71 s,中位数9.81(7.12,12.43)s,下肢肌力减退者10例(10.53%)。多因素Logistic回归分析显示,血清25(OH)D3是MHD患者下肢肌力减退的保护性因素[OR=0.761,95%CI(0.592~0.978),P=0.033]。进一步ROC曲线分析显示,25(OH)D3对应的ROC曲线下面积为0.815,其预测MHD患者发生下肢肌力减退的敏感度为80.00%,特异度为80.00%。 结论MHD患者血清25(OH)D3水平普遍较低,下肢肌力减退者更为明显;血清维生素D水平对MHD患者是否存在下肢肌力减退具有较好的预测价值。 相似文献

We propose a high order finite difference linear scheme combined with a
high order bound preserving maximum-principle-preserving (MPP) flux limiter to
solve the incompressible flow system. For such problem with highly oscillatory structure but not strong shocks, our approach seems to be less dissipative and much less
costly than a WENO type scheme, and has high resolution due to a Hermite reconstruction. Spurious numerical oscillations can be controlled by the weak MPP flux
limiter. Numerical tests are performed for the Vlasov-Poisson system, the 2D guiding-center model and the incompressible Euler system. The comparison between the linear
and WENO type schemes, with and without the MPP flux limiter, will demonstrate the
good performance of our proposed approach. 相似文献

This study aimed to understand the perceived effects of the COVID-19 pandemic on physical activity, recreation walking, and use of recreational facilities; and if the COVID-19 pandemic amplified disparities in physical activity, recreational walking, and use of recreational facilities related to the levels of neighborhood disadvantage. Recreational walking and the use of neighborhood streets and green spaces significantly decreased in high deprivation areas but not in low deprivation areas during the pandemic. While COVID-19 has negatively affected overall recreational activities, the inequitable impact on recreational walking and use of outdoor recreational facilities has been more evident in disadvantaged neighborhoods with greater deprivation. 相似文献

ObjectiveIdentify the effects of multi-directional, high intensity exercise on VOMS symptom scores in male and female recreational, college-aged athletes.DesignCross-sectional study.SettingAthletic Therapy facility.ParticipantsA convenience sample of 29 (15 females, 14 males; 21.48 ± 1.40 years old) healthy recreational athletes.Main outcome measuresVOMS symptom scores pre, immediately post-, and 10 min post a multidirectional, high intensity intermittent exercise protocol (HIIP). Friedman tests and Wilcoxon Signed Rank tests identified significant differences at the time points. A Mann-Whitney U Test investigated the effect of sex.ResultsThe majority of component and overall VOMS symptom scores increased post-HIIP (p < 0.001–0.007, effect sizes 0.39–0.50) and 10 min post-HIIP (p = 0.003–0.015, effect sizes 0.32–0.39). Near point convergence distance increased immediately post-HIIP (p < 0.001, effect size 0.52). Females had higher smooth pursuits (z = −2.340, p = 0.019, r = 0.31), vertical vestibular ocular reflex (z = −2.81, p = 0.04, r = 0.39) visual motion sensitivity (z = −2.312, p = 0.021 r = 0.30) and overall VOMS symptom scores (z = −2.84, p = 0.04, r = 0.27) 10 min post-HIIP.ConclusionsMultidirectional, high intensity exercise can induce concussive-like changes in VOMS symptom scores in healthy, recreational athletes, particularly in females. These results may assist in SRC assessment and management of athletes involved in multidirectional, high intensity sports. 相似文献
