BCAN基因在肾透明细胞癌中的表达及临床意义

目的以基因表达数据集资料为研究对象,分析BCAN基因在肾透明细胞癌中的表达情况以及对患者预后的影响。方法在Oncomine数据库中挖掘BCAN在肾透明细胞癌(ccRCC)中的表达情况。从TCGA数据库中获取ccRCC患者临床资料和目的基因的表达信息并进行统计分析。利用GEO数据库中GSE73731数据集的ccRCC样本进行基因富集分析。利用String数据库分析与BCAN相关的蛋白。结果BCAN低表达组的ccRCC患者在病理分期及T分期方面低于高表达组(P<0.001;P=0.001);N分期及M分期差异无统计学意义(P>0.05)。BCAN低表达组患者的总生存期优于高表达组(P=0.033)。BCAN基因高表达组的样本主要富集在KRAS信号通路。结论BCAN可以通过多种途径来促进肿瘤细胞的侵袭能力,有望成为ccRCC不良预后的重要生物标志物之一。     

电针对缺血性脑卒中大鼠记忆功能及脑内突触囊泡蛋白的影响

观察电针对缺血性脑卒中大鼠记忆功能及脑内突触囊泡蛋白（synaptic vesicular protein，SYN）的影响，探讨其可能的作用机制。方法 选取90 只SD大鼠随机分为模型组、电针组、假手术组，每组各30只。线拴法制作急性大脑中动脉缺血大鼠模型。电针组取“百会”“水沟”“内关”“三阴交”穴位，应用“醒脑开窍”法进行电针，每天电针30 min，连续电针6 d休1 d，7 d为一个疗程，首次电针干预在造模成功24 h后进行。模型组和假手术组不进行电针干预。大鼠分别按7、14、21 d 3个亚组进行运动及记忆功能评分，TTC染色测定脑梗死体积、Western blot检测脑内SYN的蛋白表达。结果 电针组运动功能评分较模型组显著降低（P<0.01），电针组进入隐藏区潜伏期时间较模型组显著缩短（P<0.01），电针组脑梗死率较模型组显著缩小（P<0.01），SYN的蛋白表达电针组较模型组明显增强（P<0.01）。假手术组无神经功能缺损及脑梗死灶，SYN表达最弱。结论 电针干预能减小脑梗死体积，上调脑内SYN的表达，进而促进缺血性脑卒中大鼠的记忆及运动等神经功能的恢复。

Correlates of Mental Illness and Health Categories among Older Adults in China: An Empirical Study Based on the Two Continua Model

Objective: Keyes’ two continua model is a useful concept in which mental health and mental illness exist on two separate axes. Based on this model, this study examined the prevalence and correlates of three mental health categories among older adults in China.

Methods: Cross-sectional data were derived from Wave 1 of the Study on Global AGEing and Adult Health. Participants were categorized into complete mental health (CMH), complete mental illness (CMI), and moderate mental health (MMH) groups. Multinomial logistic regressions were used.

Results: The prevalence of CMH, CMI, and MMH in China was 18%, 16%, and 66%, respectively. Being female, unmarried, younger, and feeling unhealthy were more likely to result in placement in the CMI category. Employment, education, and cognitive function were identified as important protective factors of CMH. Age, income, urban or rural residence, and physical function difficulty were associated with all three categories.

Discussion: We demonstrated the utility of the two continua model in identifying mental health needs in Chinese contexts. The findings suggest that future policy reforms and clinical interventions should establish a more comprehensive mental health category as a screening tool nationwide. The promotion of social engagement could play an important role in treating mental illness and improving positive mental health.
