The impact of dusk phenomenon on total glucose exposure in Chinese people with type 2 diabetes

This study was aimed at assessing the impact of the dusk phenomenon on the total glucose exposure in Chinese people with type 2 diabetes.A total of 380 type 2 diabetes who received a retrospective continuous glucose monitoring system (CGMs) for 72 hours were enrolled in our study, 32 of them failed in CGMs. The patients were first divided into 2 groups: dusk phenomenon (n = 95) and non dusk phenomenon group (n = 253). The magnitude of the dusk phenomenon (δDusk) was quantified by pre-dinner glucose minus post-lunch 2 hours glucose. A persistent δDusk ≥ 0 or a once only δDusk < 0 can be diagnosed with the dusk phenomenon. The participants were secondarily matched for the post-lunch 2 hours glucose to assess the impact of the dusk phenomenon on the overall glucose exposure. The impact of the dusk phenomenon was assessed on high-performance liquid chromatography assay (HbA1c) and 24-hour mean glucose.There were 95 of 348 (27.3%) participants with the dusk phenomenon in the overall population, and the median of δDusk level was –0.8 (–1.8, 0.2) mmol/L. The median of glucose differences between the 2 paired groups were 0.4 (–0.4, 1.0)% for HbA_1c, 0.9 (0.2, 1.4) mmol/L for 24 hours mean glucose. The correlation analysis showed no relationship between the magnitude of dawn phenomenon and the dusk phenomenon (r = 0.052, P = .472).The incidence of dusk phenomenon is about 27.3% in people with type 2 diabetes. The impacts of dusk phenomenon on HbA1c and 24-hour mean glucose were about 0.4% and 0.9 mmol/L and the dusk phenomenon was not related with the dawn phenomenon.     

Two novel genetic variants in the STK38L and RAB27A genes are associated with glioma susceptibility

Glioma is the most common malignant primary brain tumors with poor prognosis. Genome wide association studies (GWAS) of glioma in populations with Western European ancestry were completed in the US and UK. However, our previous results strongly suggest the genetic heterogeneity could be important in glioma risk. To systematically investigate glioma risk–associated variants in Chinese population, we performed a multistage GWAS of glioma in the Han Chinese population, with a total of 3,097 glioma cases and 4,362 controls. In addition to confirming two associations reported in other ancestry groups, this study identified one new risk-associated locus for glioma on chromosome 12p11.23 (rs10842893, p_meta = 2.33x10-12, STK38L) as well as a promising association at 15q15-21.1 (rs4774756, p_meta = 6.12x10-8, RAB27A) in 3,097 glioma cases and 4,362 controls. Our findings demonstrate two novel association between the glioma risk region marked by variant rs10842893 and rs4774756) and glioma risk. These findings may advance the understanding of genetic susceptibility to glioma.     

晚期非小细胞肺癌患者化疗对免疫功能的影响

目的探讨化疗对晚期非小细胞肺癌(NSCLC)患者免疫功能的影响,分析化疗导致的不良反应与免疫功能和肺部感染的相关性,提高晚期NSCLC化疗患者的生命质量和治疗的耐受性。方法回顾性分析2009年1月-2012年6月127例Ⅲ~Ⅳ期的NSCLC行化疗治疗患者临床资料,评价其治疗后的不良反应,采用流式细胞仪检测CD3+、CD4+、CD8+和CD4+/CD8+比值,统计肺部感染发生率,并分析肺部感染的相关危险因素。结果33例发生肺部感染,发生率为25.98%;化疗后不良反应主要以消化道症状为主,发生率为44.80%,其中Ⅰ~Ⅱ度占18.90%,Ⅲ~Ⅳ度占25.98%;白细胞减少发生率为37.79%,其中Ⅰ~Ⅱ度占14.96%、Ⅲ~Ⅳ度占22.83%;治疗后CD3+、CD4+、CD8+和CD4+/CD8+比值均明显下降,与治疗前比较差异均有统计学意义(P<0.05);logistic回归分析显示,年龄、白细胞减少、化疗疗程、肿瘤分期和CD4+/CD8+降低是肺部感染的独立危险因素(P<0.05)。结论晚期NSCLC患者化疗后的骨髓抑制和免疫功能下降是造成肺部感染的主要原因。     

宫颈癌治疗后继发性双下肢淋巴水肿患者的护理

对19例宫颈癌治疗后继发性双下肢淋巴水肿患者行手法引流综合消肿治疗,包括手法淋巴引流、弹性绷带包扎、功能锻炼等,治疗1个疗程,患者下肢周径较治疗前明显减小、水肿程度减轻,皮肤肿胀感与肢体沉重感均减轻,皮肤纤维化程度明显降低,临床症状显著改善,住院16～23 d出院。提出加强双下肢水肿的评估、皮肤护理、手法淋巴引流的护理、绷带包扎护理、功能锻炼指导、心理护理及延续护理,可提高双下肢淋巴水肿患者治疗效果。     

天麻钩藤饮加减对妊娠期高血压疾病患者RSS系统的影响

目的观察天麻钩藤饮加减对妊娠期高血压疾病(HDCP)患者RSS系统的影响。方法将160例HDCP患者随机分为治疗组和对照组各80例。对照组给予硫酸镁注射液静脉滴注;治疗组在硫酸镁注射液治疗基础上加用天麻钩藤饮加减治疗。于两组治疗前和治疗72 h后比较血压、24 h尿蛋白定量及血清肾素活性(PRA)、血管紧张素Ⅱ(AngⅡ)水平变化。结果两组治疗后收缩压和舒张压与治疗前比较均明显下降,差异均有统计学意义(P0.01)。治疗后,治疗组收缩压和舒张压显著优于对照组,与对照组比较差异具有统计学意义(P0.01)。两组治疗后24 h尿蛋白定量与治疗前比较均明显下降,差异均有统计学意义(P0.01)。治疗后,治疗组24 h尿蛋白定量显著优于对照组(P0.01)。治疗后,治疗组血清肾素活性(PRA)和血管紧张素Ⅱ(AngⅡ)下降明显(P0.01)。结论在硫酸镁解痉药物治疗基础上应用天麻钩藤饮加减治疗HDCP能够显著改善患者血压和24 h尿蛋白定量,其作用可能与降低血清PRA和AngⅡ水平有关。     

从厥阴论治溃疡性结肠炎

溃疡性结肠炎涉及或寒、或热、或寒热错杂、或风火相煽、或肝气橫逆脾土等证型,其寒热夹杂、阴阳变动、变化迅速的特点与厥阴气机下陷、厥阴气机直升、厥阴中化等特点相契合。厥阴下陷生寒,可见大便溏稀、白多赤少、畏寒、肢冷等症,当补肝体助肝用、温益元阳以固护萌芽之气;厥阴直升化热,可见下利脓血、赤多白少、腹胀、腹痛、口渴咽干、牙龈肿痛等症,当清热解毒、涩肠止痢,同时顾护既脱之元气;厥阴中化化火,可见大便夹杂脓血、肛门坠胀、胸胁满闷、干呕、默默不欲饮食、善太息等症,当以甘而缓急、散瘀清热为法以透达郁热。临床上,从厥阴气机下陷、厥阴气机直升、厥阴中化三方面综合分析溃疡性结肠炎,并结合厥阴肝与中焦脾胃五行相克的关系,在整个治疗过程考虑中宫土气、顾护中焦,可相对全面地理解溃疡性结肠炎的症状及病机变化特点,提高临床疗效。
