Complete blood count alterations in COVID-19 patients: A narrative review

Coronavirus disease 2019 (COVID-19) pandemic represents a scientific and social crisis. One of the main unmet needs for coronavirus disease 2019 is its unpredictable clinical course, which can rapidly change in an irreversible outcome. COVID-19 patients can be classified into mild, moderate, and severe. Several haematological parameters, such as platelets, white blood cell total count, lymphocytes, neutrophils, (together with neutrophil-lymphocyte and platelet-lymphocyte ratio), and haemoglobin were described to be associated with COVID-19 infection and severity. The purpose of these review is to describe the current state of the art about complete blood count alterations during COVID-19 infection, and to summarize the crucial role of some haematological parameters during the course of the disease. Decreased platelet, lymphocyte, haemoglobin, eosinophil, and basophil count, increased neutrophil count and neutrophil-lymphocyte and platelet-lymphocyte ratio have been associated with COVID-19 infection and a worse clinical outcome. Our study adds some novelty about the identification of effective biomarkers of progressive disease, and might be helpful for diagnosis, prevention of complications, and effective therapy.     

Detection of Helicobacter pylori using nested polymerase chain reaction in gastric biopsy samples

Helicobacter pylori remains a controversial organism with regards to humans, its epidemiology still unclear nearly two decades after discovery. The present study was undertaken to estimate the prevalence of the organism in the gastrointestinal tract in symptomatic and asymptomatic subjects to understand its precise natural history in India. A total of 154 specimens were a part of the study. These included gastric biopsies from peptic ulcer disease and Non ulcer dyspepsia subjects, as visualized on endoscopy, saliva and stool samples from apparently normal healthy adults. Nested polymerase chain reaction was performed using the primers Hp1, Hp2, Hp3 targeting 16S rRNA gene. A prevalence of 65.1%, 100%, 66.7%, and 73.3% respectively was observed by polymerase chain reaction. No association was observed between the H.pylori status and the disease condition of the patient.     

Relationship between hs-CRP and cardiac efficiency in chronic alcoholics

High sensitive C-reactive protein (hs-CRP), a non-specific marker of inflammatory status has considerable interest focused due to its ability to predict myocardial infarction, stroke, peripheral arterial disease and sudden cardiac death. Alcoholics are known to be associated with inflammation of heart. This study was taken up to look for an association between consumption of alcoholic beverages over 10 years and serum concentration of hs-CRP. 3 groups were studied, 30 age matched control, 30 non-drinkers with cardio vascular complications and 30 alcoholics with history of cardio-vascular disease. Blood was analyzed for hs-CRP. Results indicated that the level of hs-CRP was 0.17 ± 0.16 mg/lit in group 1; 0.79 ± 0.41 mg/lit in group 2 and 1.67 ± 0.16 mg/lit in group 3. A correlation was also obtained between the hs-CRP levels and cardiac efficiency in chronic alcoholics. The elevated hs-CRP levels in chronic alcoholic with heart disease could probably be due to enhanced damaging effect of alcohol on the heart and other organs.

血管紧张素转化酶基因I/D多态性与高血压脑梗塞发病的相关性

采用PCR方法分别检测82例高血压合并脑梗塞患者(BI)、67例单纯高血压患者(EH)和95例健康对照者(C)的血管紧张素转化酶(ACE)基因I/D多态性类型,并分析ACE基因I/D多态性分布与高血压合并脑梗塞发病的相关性.结果显示,BI组ACE基因的D/D基因型频率和D等位基因频率(分别为0.341和0.524)显著高于C组(分别为0.200和0.374,P<0.05)和EH组(分别为0.179和0.358,P<0.05),而EH组和C组ACE基因的D/D基因型频率和D等位基因频率无显著性差异.该研究结果表明,ACE基因的D/D基因型可能是高血压合并脑梗塞发病的独立危险因素.     

人体器官芯片

人体器官芯片是一门新兴的前沿科学技术,也是一门典型的多学科交叉汇聚技术,对人类健康和生物产业发展具有重要战略意义,吸引了来自政府、科学界和产业界的关注,被2016年达沃斯世界经济论坛列为"十大新兴技术"之一。人体器官芯片指的是一种在载玻片大小芯片上构建的器官生理微系统,包含有活体细胞、组织界面、生物流体和机械力等器官微环境关键要素。它可在体外模拟人体不同组织器官的主要结构功能特征和复杂的器官间联系,用以预测人体对药物或外界不同刺激产生的反应,在生命科学和医学研究、新药研发、个性化医疗、毒性预测和生物防御等领域具有广泛应用前景。文章概述性介绍了人体器官芯片的起源、国际发展态势和研究进展,并对其面临的挑战和未来发展趋势予以展望。     

植物先天免疫研究现状与前景展望

因病原微生物侵染导致的植物病害对农作物的产量和质量造成了巨大损失,也对我国的粮食安全构成重大威胁。化学农药能够较有效地控制农作物病害,但其大量施用也给环境带来了巨大污染。植物和病原微生物在漫长的相互作用过程中形成了互相识别、共同进化的机制。深刻理解农作物与病原微生物间的识别与互作分子机制,可以加快农作物抗性品种分子育种,从而减少化学农药的施用。近十多年来,植物免疫识别和病原微生物致病性的分子机理研究取得了显著进展,并逐渐形成了植物与病原微生物分子互作的进化模型,这些成果为农作物的抗病性研究和病原微生物的致病功能解析奠定了基础,也为利用现代生物技术改良植物抗病性提供了新的策略和思路。文章综述了植物先天免疫研究的重要进展,并探讨了未来的重要研究方向。
