目的探讨中医综合健康管理模式对产妇产褥期恢复的干预作用。方法选取2023年1月—2023年8月在阳江市人民医院产科分娩的产妇60例,采用随机数字表法将其分为常规健康管理组和中医综合健康管理组,每组30例。2组均给予常规产后检查指导,开展产褥期护理、母乳喂养指导等一般健康指导,中医综合健康管理组在此基础上给予饮食药膳、情志、中医适宜技术、随访指导等健康指导,随访2组产妇临床症状、恶露情况、母乳喂养情况、心理状况(SAS评分、SDS评分)、健康知识知晓度等。结果中医综合健康管理组干预效果明显优于常规健康管理组(P<0.05),前者在产后42 d、3个月中医证候评分、SAS评分、SDS评分以及母乳喂养情况和婴儿皮肤护理方法等健康知识知晓度均较常规健康管理组更优(P<0.05)。结论中医综合健康管理模式对产妇产后身心恢复具有重要的促进作用,能明显缓解产后腹痛、腰酸等临床症状,促进产后子宫复旧,缓解产后焦虑、抑郁等不良情绪,消除潜在隐患,从而达到促进、改善产妇健康的目的。

目的探索套细胞淋巴瘤(MCL)患者不同维持治疗策略的生存差异。方法收集1999年4月至2019年12月多家中心诊治的693例MCL患者临床资料,其中维持治疗组309例,总结不同维持治疗组患者的特征,进行Kaplan-Meier生存及预后分析。结果本组研究总体3年和5年无进展生存(PFS)率分别为(73.5±2.9)%和(53.6±4.3)%,3年和5年总生存(OS)率分别为(94.2±1.5)%和(82.7±3.2)%。不同维持治疗策略组患者临床特征基本一致,利妥昔单抗组、来那度胺组、布鲁顿酪氨酸激酶抑制剂(BTKi)组、双药治疗组,3年PFS率分别为(70.4±4.1)%、(69.1±7.6)%、(86.9±5.0)%和(80.4±5.1)%,3年OS率分别为(92.9±2.4)%、(97.3±2.7)%、(97.9±2.1)%和(95.3±2.7)%,差异无统计学意义(P=0.632、0.313)。多因素生存分析显示MCL国际预后指数(MIPI)高危组、维持治疗前完全缓解是PFS的独立危险因素;MIPI高危组、高剂量阿糖胞苷、治疗线数、早期疾病进展(POD24)为OS独立危险因素。结论通过比较MCL的不同维持治疗策略,初步显示BTKi在维持治疗中有获益趋势,同时患者危险分层及维持治疗前缓解状态是影响疾病进展的重要因素。

C-repeat binding proteins （CBFs） are a group of transcription factors that have been proven to be important for stress tolerance in plants. Many of these transcription factors transactivate the promoters of cold-regulated genes via binding to low temperature-or dehydration-responsive c/s-elements, thus conferring plants cold acclimation. In the present study, we isolated a C-repeat binding transcription factor from maize using the yeast one-hybrid system with the C-repeat motif from the promoter of the Arabidopsis COR15a gene as bait. The isolated transcription factor is highly similar to the Arabidopsis CBF3 in their predicted amino acid sequences, and is therefore designated ZmCBF3. Point mutation analyses of the ZmCBF3-binding c/s-element revealed （A/G）（C/T）CGAC as the core binding sequence. Expression analyses showed that ZmCBF3 was upregulated by both abscisic acid and low temperature, and was actively expressed during embryogenesis, suggesting that ZmCBF3 plays a role in stress response in maize.

为科学评估我国优势天敌昆虫叉角厉蝽Eocanthecona furcellata对重要农业害虫草地贪夜蛾Spodoptera frugiperda的捕食作用,在笼罩条件下,采用功能反应方法评价了叉角厉蝽3龄和5龄若虫及雌成虫对草地贪夜蛾3龄和5龄幼虫的捕食能力。研究表明,除叉角厉蝽3龄若虫不能独立捕食草地贪夜蛾5龄幼虫外,叉角厉蝽其它虫态对草地贪夜蛾幼虫的捕食量均随猎物密度的升高而增加,捕食率则随猎物密度的升高而逐渐下降,经Logistic回归方程判别为II型功能反应。拟合的Rogers’随机捕食者方程参数表明,叉角厉蝽3龄和5龄若虫及雌成虫对草地贪夜蛾3龄幼虫的瞬时攻击率a分别为0.0295、0.0453和0.0965,处置单头猎物的时间Th分别为3.98 h、1.36 h和1.21 h,理论日最大捕食量T/Th分别为6.03头、17.65头和19.83头;叉角厉蝽5龄若虫和雌成虫对草地贪夜蛾5龄幼虫的瞬时攻击率a分别为0.0545和0.0876,处置单头猎物的时间Th分别为3.67 h和4.83 h,理论日最大捕食量T/Th分别为6.54头和4.97头。结果表明,在笼罩条件下叉角厉蝽3龄若虫的捕食能力最弱,除不能有效捕食草地贪夜蛾5龄幼虫外,对草地贪夜蛾3龄幼虫的捕食量也远低于5龄若虫和雌成虫,而叉角厉蝽5龄若虫和雌成虫的捕食能力较强,能有效捕食草地贪夜蛾的3龄和5龄幼虫,两者的捕食量相近。研究结果可为合理利用叉角厉蝽防治草地贪夜蛾提供实践参考。

Nanocrystalline surface layers and gradient nanostructure in 5182 aluminum alloy have been produced through surface mechanical attrition treatment(SMAT). The results indicate that the gradient nanostructure can not only improve the mechanical properties of 5182 Al alloy, but also has a certain effect on the Portevin-Le Chatelier(PLC) effect. The yield and ultimate tensile strength of 5182 Al alloy with SMAT are significantly improved combining with the decrease of fracture elongation compared with the as-received one. The PLC effect of 5182 Al alloy could be effectively postponed by the formation of gradient nanostructure after SMAT. It leads to the increase of critical strain of the PLC effect, more concentrated distribution of serrated strain, and increase of average stress amplitude in special strain range. The influence of grain size and gradient nanostructure on the PLC effect of 5182 Al alloy was also discussed in detail. Grain refinement could sharply increase the density of dislocations and hinder the movement of dislocations, which results in the decrease of moving speed of dislocations and the more concentrated distribution of solute atoms. The solute atoms would aggregate to form nano precipitates and further impede movement of dislocation. The stronger interaction between the dislocations and the nano precipitates is the main mechanism of postponed PLC effect.
