Copper and Zinc Levels in Myelodysplastic Syndrome Patients versus Healthy Subjects

Background: Myelodysplastic syndrome (MDS) is a heterogeneous hematological disease and certain serum factors are assumed to be involved in its pathogenesis and progression. Given this, our aim was to comparatively investigate the copper, zinc, and iron levels in MDS patients and healthy individuals. Methods: This case-control study was conducted on 31 patients with MDS (according to the WHO criteria after investigating laboratory tests such as peripheral blood smear and bone marrow aspiration) attending Bahonar Hospital, Kerman, Iran, and 31 healthy subjects from 2016 to 2018. The levels of copper, ceruloplasmin, zinc, ferritin, and iron were compared between the two groups. Results: Among the MDS patients, five individuals (16.13%) had low serum copper level (mean: 67.8 ± 4.35 µg/dl). Serum copper level was 111.3 ± 27.7 and 138.3 ± 26.6 in case and control groups, respectively (P = 0.0001). The serum zinc level and bone marrow iron level were also significantly different between the two groups (P < 0.05). Conclusion: Overall, it can be concluded that because only a small proportion of the MDS patients enrolled in this study were found to have lower copper levels compared with the MDS patients population, further studies with a larger sample size and also clinical trials in MDS patients with serum zinc, and copper deficiency are recommended, and post-treatment hematological reassessment would also be beneficial to achieving more definitive results.

新疆拜城县重病区与中病区内外环境无机元素含量的调查

本文于１９９３年４月调查了新疆拜城县重病区查尔齐农场中与中病区赛里木乡的饮水，土壤，粮食，学龄儿童头发中Ｚｎ，Ｃｕ，Ｍｎ，Ｃａ，Ｌｉ，Ｓｅ６种元素无机元素的含量。结果表明，重病区小麦中Ｃａ的含量显著高于中病区（Ｐ〈０．０５），重病区饮水及小麦中Ｍｎ的含量显著低于中病区（Ｐ〈０．０５）。这些结果揭示重病区查尔齐与中病区赛里木乡的病情相比较，除缺碘较为严重这一主要原因之外，高Ｃａ，低Ｍｎ也可能与查尔齐     

肾虚型牙周炎患者血清锌水平的变化

应用原子吸收光谱分析法检测了４０例牙周炎患者和１９例健康人血清锌水平，结果表明：牙周炎患者血清锌水平呈降低趋势，但差异无显著性；根据患者病情的轻重程度和中医辨证分析显示：牙周炎患者血清锌水平的降低不仅与其病情的严重程度呈负相关，而且肾虚型牙周炎患者的血清锌水平明显低于健康人和无肾虚型牙周炎组（Ｐ〈０．０５），无肾虚型牙周炎组与健康人之间血清锌水平无显著差异（Ｐ〉０．０５），提示：血清锌水平的降低…

Deficient IFNα production in hairy cell leukemia

Summary Since the application of low doses of IFN-alpha is necessary to maintain remissions in Hairy Cell Leukemia (HCL) it is of interest whether peripheral blood mononuclear cells (MNC) of HCL patients can be induced in vitro to produce IFN-alpha. 9 patients suffering from advanced HCL were included in the study. The diagnoses were confirmed by characteristic findings in peripheral blood and bone marrow biopsies. For IFN treatment we initially used natural IFN-alpha (Bioferon) and switched later to recombinant IFN-alpha₂ (Boehringer). MNC of 5 patients before IFN therapy and of 6 patients during IFN therapy (2–47 weeks) were induced by phythemagglutinin (PHA), Corynebacterium parvum (C.p.), and sendai virus (SV). PHA is known to induce IFN-gamma. Both, C.p. and SV induced IFN-alpha but no IFN-gamma in MNC of healthy controls and of IFN treated breast cancer patients. In HCL patients normal antiviral activities could be induced by PHA. Zero or only low antiviral activities could be induced in MNC from 9 patients tested on 22 occasions. It is concluded that MNC from patients with advanced HCL can be induced to produce IFN-gamma but no IFN-alpha. Since IFN-alpha but not IFN-gamma is produced by monocytes it is likely that reduced numbers of monocytes which were found in our HCL patients before and during IFN treatment account for the described deficiency of IFN-alpha production.     

基于“气血”理论探讨中医治疗肺系疾病之思路

中医学认为,气血失和,百病丛生,气血是构成人体和维持其生命活动的物质基础。现基于气血理论探讨中医治疗肺系疾病的辨治思路,认为肺系疾病的发病与气血关系密切,系因机体气血功能异常,加之外邪侵袭,导致“肺气虚弱,肺虚络瘀,肺热瘀阻,热壅血瘀”,总结出主要病机是“气血亏虚为本,痰热瘀阻为标”,治疗上应以“调和阴阳、理顺气血”为主要原则,临床上辨证应用“补肺理气、养血活血、化痰逐瘀、清肺热、利肺气、止咳平喘、凉血”之法,为临床从气血角度论治肺系疾病提供新思路。
