116例冠心病患者血清中钙镁钡铝锶含量的研究

测定１１６例冠心病患者血清中钙，镁，钡，铝和锶的含量并与正常值比较，常量元素钙，镁和微量元素锶降低，而微量元素钡和铝升高，它们之间的差异都有显著或高度显著性。Ｐ〈０．０５或Ｐ〈０．０１。     

Detection and assessment of citrus tristeza virus antigens by computer-aided scanning densitometry

Citrus tristeza virus (CTV) extracted from Etrog citron (C.medica L.) was immunoprecipitated. The immunoprecipitate was fractionated by SDS-PAGE and western blotted onto nitrocellulose. The CTV antigens were determined by immunoblot analysis using rabbit anti-CTV IgG, and the protein-band pattern exhibited on the nitrocellulose was assessed by soft-laser scanning densitometry. The densitometric tracing revealed the presence of bands that were not visible to the naked eye. Using the superimposition mode of the instrument, it was also revealed that the protein-band patterns of different CTV samples were not identical. Computer-aided soft-laser scanning densitometry proved to be a powerful approach in the detection and assessment of protein bands revealed on nitrocellulose immunoblots, which we were previously unable to do employing conventional methods.     

化工工人体内微量元素积累与健康的关系

论述了化工作业工人长期接触有害元素会引起体内有害元素积蓄，微量元素平衡失调，产生潜在的职业危害，建议定期对临床尚未发现中毒现象的作业工人进行体内微量元素情况监控，以预防职业中毒。并提出采用适当补充某些必需元素的方法，可预防这种危害。     

Controllable and flexible cellular network for virus cell-to-cell spread

Cellular networks were constructed based on PEG modification and soft lithography, in which cell numbers and spatial distributions can be controlled. A micro-injector was combined with cellular networks to fix virus induced plaque and virus spread direction, by which virus cell-to-cell spread can be distinguished from cell-free spread.     

内蒙古牧区老年冠心病患者血清Zn,Cu,Ca,Mg的测定及临床意义

用薄样Ｘ射线荧光光谱法测定较区９１老年冠心病患者及６３名老年健康人血清Ｚｎ、Ｃｕ、Ｃａ、Ｍｇ、四种元素的含量。结果表明：牧区老年冠心病患者血清中Ｚｎ、Ｃｕ、含量与健康组比较无显著差异，但两者的比值高于对照组，可能与牧区牧民饮食习惯有关；老年冠心病组血清Ｃａ、Ｍｇ含量显著低于对照组。

Genomic variation and point mutations analysis of Indian COVID-19 patient samples submitted in GISAID database

Corona virus disease 2019 (COVID-19) endemic has havoc on the world; the causative virus of the pandemic is SARS CoV-2. Pharmaceutical companies and academic institutes are in continuous efforts to identify anti-viral therapy or vaccines, but the most significant challenge faced is the highly evolving genome of SARS CoV-2, which is imparting evolutionary selective benefits to the virus. To understand the viral mutations, we have retrieved nine hundred and thirty-four samples from different states of India via the GISAID database and analyzed the frequency of all types of point mutation in all structural, non-structural proteins, and accessory factors of SARS CoV-2. Spike glycol protein, nsp3, nsp6, nsp12, N and NS3 were the most evolving proteins. High frequency point mutations were Q496P (nsp2), A380V (nsp4), A994D (nsp3), L37F (nsp6), P323L & A97V (nsp12), Q57H (ns3), D614G (S), P13L (N), R203K (N), G204R (N) and S194L (N).

Chemical composition of the volatile oil from Cynanchum stauntonii and its activities of anti-influenza virus

The volatile oil of the roots of Cynanchum stauntonii was examined by gas chromatography–mass spectrometry (GC–MS). Thirty-eight constituents were identified. (E,E)-2,4-Decadienal, 3-efhyl-4-methypentanol, 5-pentyl-3H-furan-2-one, (E,Z)-2,4-decadienal and 2(3H)-furanone,dihydro-5-pentyl were found to be the major components. The volatile oil exhibited the activities against influenza virus in vitro (IC₅₀s = 64 μg/ml). In in vivo experiment, it prevented influenza virus-induced deaths in a dose-dependent manner.
