变异型心绞痛的发作诱因和合并症

本文报告3例饮酒诱发变异型心绞痛者,2例发展为急性心肌梗塞,1例合并Ⅲ度房室传导阻滞.另3例无诱因的典型变异型心绞痛发作皆无合并症.上述结果提示:饮酒是变异型心绞痛发作的最常见诱因,与无诱因者相比,予后更为严重.因此,有冠状动脉痉挛倾向者如变异型心绞痛,不稳定型心绞痛,卧位或夜间发作的心绞痛等,应避免饮酒.     

放松训练对高考学生身心健康的影响

目的　研究放松训练法对高考学生身心健康的影响 ,为考生心理健康水平的提高 ,减轻考前焦虑提供科学措施。方法　选择同一学校两个高中三年级的班级 ,分别作为对照组 ( n=72 )和放松训练组 ( n=70 )。高考前的 3个月开始进行全身放松训练 ,每天约 2 5分钟 ,连续两个半月。比较训练前后两组考生的心理健康水平 ,并评价放松训练法的作用效果。结果　对照组考生在考前半个月 SCL-90的阳性项目数以及焦虑、强迫、躯体化、人际敏感、抑郁等 5项因子分和 SAS总均分均显著高于 3个月前 ;放松训练组考生经 2个半月的放松训练后 ,其 SCL-90的焦虑、强迫、人际敏感、抑郁、躯体化等 5项因子分和 SAS总均分均显著低于放松训练前 ,且阳性项目数、总均分以及焦虑、强迫、抑郁、躯体化、人际敏感等 5项因子分和 SAS总均分均显著低于对照组高考前半月的相应分值。结论　随着高考的临近 ,考生的心身反应增多且加重 ,心理健康水平明显下降 ;全身放松训练法能有效改善考生的各种心身反应和紧张焦虑状况 ,有利于保护考生的心理健康

Tumor microenvironment immune subtypes for classification of novel clear cell renal cell carcinoma profiles with prognostic and therapeutic implications

Currently, no effective prognostic model of clear cell renal cell carcinoma (ccRCC) based on immune cell infiltration has been developed. Recent studies have identified 6 immune groups (IS) in 33 solid tumors. We aimed to characterize the expression pattern of IS in ccRCC and evaluate the potential in predicting patient prognosis. The clinical information, immune subgroup, somatic mutation, copy number variation, and methylation score of patients with TCGA ccRCC cohort were downloaded from UCSC Xena for further analysis. The most dominant IS in ccRCC was the inflammatory subgroup (immune C3) (86.5%), regardless of different pathological stages, pathological grades, and genders. In the C3 subgroup, stage IV (69.1%) and grade 4 (69.9%) were the least presented. Survival analysis showed that the IS could effectively predict the overall survival (OS) (P < .0001) and disease-specific survival (DSS) (P < .0001) of ccRCC alone, of which group C3 (OS, HR = 2.3, P < .001; DSS, HR = 2.84, P < .001) exhibited the best prognosis. Among the most frequently mutated ccRCC genes, only VHL and PBRM1 were found to be common in the C3 group. The homologous recombination deficiency score was also lower. High heterogeneity was observed in immune cells and immunoregulatory genes of IS. Notably, CD4+ memory resting T cells were highly infiltrating, regulatory T cells (Treg) showed low infiltration, and most immunoregulatory genes (such as CX3CL1, IFNA2, TLR4, SELP, HMGB1, and TNFRSF14) were highly expressed in the C3 subgroup than in other subgroups. Enrichment analysis showed that adipogenesis, apical junction, hypoxia, IL2 STAT5 signaling, TGF-beta signaling, and UV response DN were activated, whereas E2F targets, G2M checkpoint, and MYC targets V2 were downregulated in the C3 group. Immune classification can more accurately classify ccRCC patients and predict OS and DSS. Thus, IS-based classification may be a valuable tool that enables individualized treatment of patients with ccRCC.

农民工全宫切除术患者配偶主观幸福感、自尊及社会支持的研究

目的探究农民工全宫切除术患者配偶主观幸福感、自尊及社会支持的关系。方法运用主观幸福感量表、自尊评定量表及社会支持评定量表对32例农民工全宫切除术患者配偶进行调查。结果农民工患者配偶不同的年龄段、职业、文化程度的生活满意度、积极情感、消极情感及总体幸福感比较均有显著差异(p<0.01);农民工患者配偶的幸福感指数与自尊总分呈正相关关系(p<0.01),幸福感指数与社会支持各因子及总分亦均呈正相关关系(p<0.01)。结论农民工全宫切除术患者配偶的幸福感指数与自尊总分和社会支持均呈正相关关系;术后性生活的满意度对其幸福感存在一定影响。
