微创治疗方法在输尿管上段结石中应用进展

输尿管上段结石为临床中常见泌尿系结石类型之一,如不能及时诊治,可引起重度积水、泌尿系感染,甚至脓毒血症,对患者肾功能、健康造成严重影响。随着微创治疗技术在泌尿系结石中应用,微创治疗方法能降低对患者造成治疗性创伤,降低相关并发症发生率,促进患者康复,了解临床中微创治疗输尿管上段结石方法,对临床中合理治疗输尿管上段结石有重要价值。     

miR-149与肿瘤关系的研究进展

miRNAs是一类长度约为20~25个核苷酸，参与基因调控表达的内源性非编码RNA。miR-149作为miRNAs的重要成员，在多种肿瘤中表达异常，其表达水平与肿瘤细胞增殖、转移、凋亡、耐药、患者的早期诊断及预后密切相关。因此，miR-149有望成为新一类抗肿瘤治疗的靶点。     

桂枝汤加减治疗营卫不和型慢性瘾疹的临床疗效

目的:观察桂枝汤加减治疗营卫不和型慢性瘾疹的临床疗效。方法:将我院门诊2017年10月-2019年10月收治的48例营卫不和型慢性瘾疹患者,按随机数表法分成对照组(24例)与实验组(24例)。对照组实施常规西药治疗,实验组实施桂枝汤合地骨皮、白鲜皮加减治疗。对照两组治疗前后症状积分、临床疗效及并发症发生率。结果:两组治疗前症状积分相比无显著差异(P>0.05)。治疗后,两组症状积分均有所下降,实验组低于对照组;实验组临床总有效率为91.67%(22/24)高于对照组的66.67%(16/24);实验组并发症发生率0(0/24)低于对照组的16.67%(4/24),差异具有统计学意义(P<0.05)。结论:在营卫不和型慢性瘾疹治疗中,采取桂枝汤加减治疗,可明显降低症状积分,提高临床治疗效果,减少并发症,效果理想。

miR-513a-5p慢病毒载体的构建及其对人骨肉瘤细胞放疗敏感性的影响

目的:构建miR-513a-5p慢病毒过表达载体，转染人骨肉瘤细胞株，观察miR-513a-5p对人骨肉瘤细胞放疗敏感性的影响。方法:PCR法扩增人miR-513a-5p基因，克隆入pLentis-CMV-GFP-MCS-PGK-PURO载体获得重组质粒pLentis-miR513a，双酶切鉴定并测序后将正确的重组质粒和对照质粒转染293FT细胞制备慢病毒，分别转染骨肉瘤HOS和U2OS细胞，qRT-PCR法及荧光显微镜鉴定转染结果。克隆形成实验、MTT法检测miR-513a-5p高表达HOS和U2OS细胞在X射线照射下细胞存活情况。结果:双酶切及测序结果确定成功构建miR-513a-5p慢病毒载体pLentis-miR513a。qRT-PCR结果提示，转染骨肉瘤细胞株后miR-513a-5p表达显著升高。克隆形成实验结果显示miR-513a-5p高表达后骨肉瘤细胞在X射线照射下细胞增殖减慢。MTT结果提示miR-513a-5p高表达骨肉瘤细胞经X射线照射后细胞存活减少。结论:成功构建了miR-513a-5p慢病毒载体，建立了高效稳定表达miR-513a-5p的骨肉瘤细胞株，高表达miR-513a-5p能显著增加X射线照射后骨肉瘤细胞的放疗敏感性。     

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.
