Nitric oxide donors offer protection to RBC from storage lesion

BackgroundRed blood cell (RBC), which is the most commonly transfused blood component, due to its ability to save a life in absence of any other blood components, can be stored up to maximum 6 weeks by following standard preservation procedure. During storage, RBC undergoes various biophysical and biochemical changes (commonly known as storage lesion) for which blood transfusion with “old RBC” shows a lot of clinical problems especially relevant to critically ill patients. Recent research on S-nitrosylation of haemoglobin to improve oxygen delivery of banked blood revealed the important role of nitric oxide (NO) in protecting storage lesion.Materials and methodsIn the present study, we used various “NO donating” chemicals with different NO release dynamics and chemistries in RBC storage cocktails to test the effects of NO on storage lesion. Changes in different storage markers were evaluated after 7 days storage of pre-treated RBC.ResultsAll the NO donors have shown protection against hemolysis. However, S-nitroso glutathione (GSNO) ranks first in shielding RBCs from storage lesion and additionally, it helps in elevating the value of 2, 3-di phosphoglycerate (2, 3-DPG), improving the RBC membrane fluidity and decreasing the adhesion towards endothelial monolayer.DiscussionPresent study reveals that NO released from NO donors confers protection against storage lesions of the RBC. Further, the study confirms that pre-treatment with GSNO, a NO donor and a nitrosylating agent, ensures the best protection to RBC during low temperature storage, when compared to other NO donor treatments.     

Effects of Long-time Exposure to Lipopolysaccharide on Intestinal Lymph Node Immune Cells and Antibodies Level in Mice

Background: Endotoxin, widely present in the living environment of humans and animals, leads to endotoxemia during a short period. However, the long-term effects of endotoxin on immune function are unclear. Objective: To determine the importance of long-term endotoxin treatment on function of immune system. Methods: The mice were treated with different doses of lipopolysaccharide (LPS) for a month; the collected samples were then analyzed in terms of value changes in hematological parameters, lymphocyte subtypes, and immunoglobulins level. Results: The number of monocytes (MONO) and neutrophils (NEU) in the three treatment groups was significantly lower than the control after 30 days. However, the proportion of CD8+ T lymphocytes showed a rising trend in the mesenteric lymph nodes (MLNs) and Peyer's patches (PPs) while the CD4+ T cell was reduced. At the same time, a decrease was observed in the percentage of CD19+CD38+ B lymphocytes. Interestingly, the change of lymphocytes in PPs was more significant than that in MLNs, suggesting that immune response in the PPs occurred before the MLNs. Consistent with the changes in B cells, the content of IgA and IgG showed a downward trend. Conclusion: Long-term exposure to low-dose endotoxin had little or no effect on the immune function of the body, suggesting that the endotoxin can be rapidly eliminated by the immune system. Nonetheless, the number of immune cells was reduced in the high-dose group. T- and B-lymphocytes were significantly reduced, resulting in a decrease in immunoglobulin level, and showing a significant immune suppression state.     

血糖变异性与重症脑出血患者神经功能恢复的相关性

目的 探讨血糖变异性对重症急性脑出血患者神经功能恢复的影响及血糖变异性在重症脑出血患者发病时间轴上的表现特点。方法 选取2018年1月1日-2019年7月1日收入河南科技大学第一附属医院重症外科的脑出血患者,根据患者入院30 d后改良Rankin(Modified Rankin scale,mRS)评分将患者分为神经功能恢复良好组(mRS≤2分),和神经功能恢复不良组(mRS>2分)(残疾/死亡),比较2组入院时高血糖、平均血糖、血糖标准差、入院24 h内血糖变异性(CV1)、入院1～3 d血糖变异性(CV2)、入院3～7 d血糖变异性(CV3)、入院7 d内血糖平均变异性(CV7)、最低血糖水平以及其他临床资料,应用多变量logistic回归分析确定入院30 d后神经功能恢复的独立预测因素。结果 单因素分析显示年龄、CV1、CV3、CV7、最低血糖水平、血糖标准差是影响重症脑出血患者神经功能恢复的相关因素(P<0.05); 多因素logistic逐步回归模型分析显示血糖标准差、CV1、CV3、CV7、最低血糖水平能独立预测重症脑出血患者神经功能的恢复情况; 神经功能恢复良好组和神经功能恢复不良组患者的血糖变异性在入院24 h内、入院1～3 d和入院3～7 d时间轴上的变化特点不同(F=5.000,P=0.029),进一步分析可以看出神经功能恢复不良组的血糖变异性平均幅度较神经功能恢复良好组高,但2组在时间轴上的变化趋势基本相同,均在急性期(入院1～3 d)呈线性上升趋势,之后趋于下降; 组内效应显示患者的血糖变异性在3个时间段上的变化具有显著差异(F=11.663,P<0.001)。结论 血糖标准差、CV1、CV3、CV7、最低血糖水平是影响重症脑出血患者神经功能恢复的独立危险因素; 在重症脑出血患者超急性期、急性期、亚急性期过程中血糖变异性的变化具有显著差异,临床工作中重症脑出血患者应在入院早期密切监测血糖,并积极干预,减小血糖波动范围,以期减少不良预后的发生。     

Comparison of processing speed,balance, mobility and fear of falling between hypertensive and normotensive individuals

BackgroundHypertension (HT) contributes substantially to poor physical function, cognitive dysfunction, cardiovascular problems and to all-cause mortality. Performance in activities requiring attention, speed and coordination might also be affected in individuals with HT.ObjectiveThis study compared the processing speed, static and dynamic balance, functional mobility and fear of falling between individuals with hypertension (HT group) and normotensive individuals (NT group).MethodsOne-hundred and twenty-eight individuals were included: NT group (n = 64) and HT group (n = 64). The Choice Stepping Reaction Time Test was used for the evaluation of processing speed, Single Leg Stance test for static balance evaluation, “Y” Balance Test for dynamic balance evaluation, Timed Up and Go test with single and dual tasking for the evaluation of functional mobility and Falls Efficacy Scale for assessing fear of falling.ResultsThe processing speed of the HT group was slower than that of the NT group; the total response time (RsT) in Stepping Reaction Test (SRT) (mean difference [MD] = −0.2, 95% CI = −0.3, 0), and Stroop Test (ST) [ST-A (MD = −0.4, 95% CI = −0.5, −0.2), ST-B (MD = −0.5, 95% CI = −0.7, −0.2) and ST-C (MD = −0.6, 95% CI = −0.8, −0.3). Additionally, the static [single leg stance, eyes open, right side (MD = 12.7, 95% CI = 6.3, 19.0) and left side (MD = 13.6, 95% CI = 7.2, 19.9)] and dynamic balance [Y balance test, composite score, right lower extremity (MD = 8.5, 95% CI = 4.4, 12.5) and left lower extremity (MD = 5.2, 95% CI = 1.5, 8.8) scores of the HT group were lower than those of the NT group. The HT group required a longer time to complete the functional mobility test measured with Timed Up And Go Test during both single task (MD = −0.8, 95% CI = −1.1, −0.4), cognitive dual task (MD = −1.5, 95% CI = −2.4, −0.5) and manual dual task (MD = −0.9, 95% CI = −1.3, −0.4) in comparison to the NT group. Also, the HT group had higher levels of fear of falling (MD = −7.6, 95% CI = −10.9, −4.2).ConclusionHypertensive individuals present slower processing speed, reduced static and dynamic balance, decreased functional mobility and higher fear of falling in comparison to normotensive individuals.
