目的探究壮通饮通过Nrf2-SCL7A11/xCT-Gpx4通路调控铁死亡对大脑中动脉栓塞模型小鼠脑缺血再灌注损伤的保护作用及其机制。方法将C57BL/6J小鼠随机分为假手术组（Sham）、模型组（MCAO）、低剂量壮通饮组（ZTY-L+MCAO），高剂量壮通饮组（ZTY-H+MCAO），每组5只。其中MCAO组采用硅胶线栓法进行造模，小鼠大脑中动脉栓塞1h，拔出线栓再灌注72h后进行心脏灌注取脑，Sham组除了不插入线栓其余操作同MCAO组。采用Zea-Longa法对小鼠神经功能进行评分；采用TTC染色评估小鼠脑梗死体积；采用HE染色、尼氏染色评估脑损伤程度；采用普鲁士蓝染色评价三价铁离子蓄积水平；qPCR检测铁离子转运相关载体受体TfR1和DMT1、脂质过氧化相关基因ACSL4以及铁死亡标志物PTGS2 mRNA表达；ELISA试剂盒检测4-HNE的含量评估小鼠大脑脂质过氧化水平；Western-blot、免疫荧光检测小鼠脑组织中Nrf2、SCL7A11/xCT、Gpx4蛋白水平。结果①壮通饮改善了MCAO/R后小鼠神经功能（P＜0.05）和大脑梗死体积（P＜0.05）及缓解MCAO/R后大脑皮层细胞病理损伤。②壮通饮减弱了MCAO/R后小鼠大脑组织的三价铁离子蓄积状态；减少MCAO/R后小鼠大脑中与铁离子转运入细胞内相关载体TfR1和DMT1 mRNA的表达（P＜0.001）；下调MCAO/R后小鼠大脑脂质过氧化物4-HNE含量和组织脂质过氧化物酶ACSL4 mRNA表达（P＜0.001）；降低MCAO/R后小鼠大脑铁死亡标志物PTGS2 mRNA表达（P＜0.001）。③壮通饮增加MCAO/R后Nrf2入核表达（P＜0.001），以及增加xCT和Gpx4在神经元中的表达（P＜0.001）。结论壮通饮能够改善MCAO/R小鼠神经功能和脑梗死体积，缓解大脑皮层细胞病理损伤，影响Nrf2-SCL7A11/xCT-Gpx4通路关键信号分子表达，所以壮通饮改善小鼠MCAO/R损伤的作用机制可能是通过Nrf2-SCL7A11/xCT-Gpx4通路调节铁死亡水平达到的。

目的探讨伴有酸中毒的家族性低钾型周期性瘫痪的诊断和治疗。方法分析先证者病史、临床表现、实验室检查和影像学特点，详细调查家系患病情况，应用二代测序技术检测低钾血症相关致病基因位点，对国内外相关文献进行归纳总结。结果明确诊断先证者为家族性低钾型周期性瘫痪，先证者的SCN4A基因有1个杂合突变，为c.2006G>A，导致氨基酸改变p.R669H。先证者的祖父、父亲和伯伯存在相同变异。结论伴酸中毒的家族性低钾型周期性瘫痪罕见，容易误诊为肾小管酸中毒，临床上要提高警惕。SCN4A基因c.2006G>A突变是该家系发病的分子基础。不同基因突变的临床表型存在差异，基因筛查有助诊断分型和治疗方案选择。

电力杆塔与5G站址开展共享共建，对提高资源利用效率、降低电信企业成本具有现实意义。构建电力杆塔与5G站址规划以及典型应用场景的规模化匹配方法，对于优化提升电力杆塔共享匹配度，摸底电力杆塔资源共享潜力，做好电力杆塔共享资源大范围推广后的统筹优化至关重要。针对电力杆塔和5G站址，构建了基于站距和站高的规模化匹配方法，以及考虑技术、政策和商业约束等情景的匹配度测算方法，并以福州长乐全域为例进行实证分析。结果显示，不同场景下电力杆塔和5G站址的匹配度差别较大，市人口密集区、工业园区匹配度可达50%，高铁沿线匹配度不足10%。若进一步考虑技术、政策、商业约束要素，则匹配度将进一步缩小，在四重要素叠加下，匹配度约为14%。虽然匹配程度不足，但考虑到全国电力杆塔和5G站址体量巨大，依然具备较大的共享潜力和良好的合作空间。

针对无线通信传统接收机的信道估计和译码分开处理是次优的问题,文章提出了一种联合信道估计和极化码译码的接收机模型。根据极化码译码器级联的循环冗余校验码的校验信息,接收机将译码器中部分硬判决信息再编码,然后将得到的码字反馈到信道估计器中,此时相当于接收机挑选了部分码字比特作为导频,信道估计器根据新的导频重新进行信道估计。文章提出的接收机模型及算法不仅减少了信道估计中导频的开销,还使得信道估计和译码两个过程相互促进,从而改善了极化码的误帧率。仿真结果表明,当归一化多普勒等于0.02时,文章提出的基于硬判决反馈的接收机相比于传统的接收机有2 dB的性能增益。

In order to evaluate the relationship between human and water quantitatively, taking Xi'an City as an example, the evaluation index system of human and water harmony was built on the basis of the concept of human and water harmony. The weights of each index were calculated by improving G1 weighting method. Based on the comprehensive development level of water system and human system, the coupling coordination model was used to calculate the coordination degree of human water system, and the obstacle factors were identified by the obstacle degree model. The evaluation method of single index quantification, multi-index synthesis and multi-criteria integration was adopted to calculate the health degree of effluent system and the development degree of human system, and then integrate with the coordination degree of human water system, and finally got the evaluation result of human water harmony in Xi'an City from 2012 to 2021. The results show that the man-water coordination degree of Xi'an City is gradually improved, and the obstacle degree of each index to the coordinated development of man-water system in each year is clearly visible, and the harmony of man-water is also improved from less harmonious to harmonious level. The evaluation results of this method are consistent with the actual results and have good applicability. The identification of obstacle factors is instructive to further improve the harmony between human and water. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effects of ropivacaine combined with parecoxib sodium serratus plane block (SAPB) on postoperative oxidative stress and immune inflammatory response in patients undergoing thoracoscopic radical resection of lung cancer. Methods: According to the random number table method, 110 patients with lung cancer who underwent thoracoscopic radical resection of lung cancer in The Sixth Affiliated Hospital of Nantong University from January 2021 to April 2023 were divided into observation group (ropivacaine combine with parecoxib sodium SAPB, 55 cases) and control group (ropivacaine SAPB, 55 cases). The postoperative recovery, visual analogue scale (VAS) of pain at rest and cough, immune function, inflammatory response and oxidative stress were compared between two groups, and the incidence of adverse reactions during treatment was observed. Results: The postoperative spontaneous breathing recovery time, eye opening time and extubation time in observation group were shorter than those in control group (P<0.05). The resting VAS and cough VAS in observation group were lower than those in control group 12 h (T2)~48 h (T4) after operation (P<0.05). The levels of superoxide dismutase (SOD), CD3+, CD4+, CD4+/CD8+ in observation group were higher than those in control group at T3 time point. Malondialdehyde (MDA), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and CD8+ were lower than those in control group(P<0.05). The adverse reactions in control group was 7.28%, and that in observation group was 10.92%, with no statistical difference(P>0.05). Conclusion: Ropivacaine combined with parecoxib sodium SAPB for thoracoscopic radical resection of lung cancer, which can effectively improve the clinical symptoms and immune function, reduce the body's inflammatory and oxidative stress.

BACKGROUND: Gait is one of the optimal indicators of functional status in older adults. Gait parameters are associated with adverse health outcomes in older adults. OBJECTIVE: To summarize and compare the practical value of gait parameters, and to review the progress of research on spatio-temporal parameters and the risk of adverse health outcomes in older adults. METHODS: PubMed, Web of Science, and CNKI were searched for relevant literature published from January 2010 to June 2023 using the search terms of “gait speed, walking speed, step length, cadence, step frequency, step time, walking base, aged and elderly” in English and Chinese, respectively. A total of 52 papers were finally included for the systematic review. RESULTS AND CONCLUSION: Currently, researchers have focused on three basic temporal-spatial parameters, namely, step speed, step length and step frequency, to explore their association with adverse health outcomes in older adults. Reduced gait speed in older adults may increase the risk of falls, all-cause mortality, and may be an independent predictor of all-cause mortality. Older adults with slow gait speed are at higher risk of cognitive decline, and may be the preferred gait parameter in assessing cognitive impairment in older adults. Older adults with slow gait speed are more likely to have debilitating or common chronic illnesses, and are at higher risk of hospitalization and public care. Step length is positively correlated with individual height and lower limb length, but age-induced shortening of step length is not related to height or lower limb length, and shortening of step length reflects reduced physical function in older adults, and shortening of step length is a risk factor for falls and cognitive decline in older adults. Stride frequency is often used as a measure of exercise intensity, and a stride frequency of ≥ 100 steps/minute is predictive of all-cause mortality, and slowing of step frequency may lead to a higher risk of falls, hospitalization and all-cause mortality in older adults. Changes in gait parameters are closely related to the level of physical fitness in older adults, and there may be a bidirectional relationship between the two. The results of the study will provide a theoretical basis for further improving risk screening in clinical populations, refining health risk assessment in the elderly, improving health protection and promoting active health in the elderly.
