Association of weight-adjusted-waist index with incident hypertension: The Rural Chinese Cohort Study

AimsTo explore the association between WWI and the incidence of HTN in the Rural Chinese Cohort Study.Methods and ResultsWe examined data for 10,338 non-hypertensive participants (39.49% men) aged ≥ 18 years from the Rural Chinese Cohort Study who completed a baseline examination during 2007–2008 and follow-up during 2013–2014. WWI was calculated as waist circumference (cm) divided by the square root of weight (kg). Multiple logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the probability of HTN across four WWI categories. Restricted cubic splines analysis was used to model the dose–response association of WWI and HTN. A total of 2078 participants had HTN during a median follow-up of 6 years. After adjusting for potential confounders, as compared with the lowest WWI category (<9.94 cm/√kg), with WWI 9.94 to 10.42, 10.42 to 10.91 and ≥ 10.91 cm/√kg, the ORs (95% CIs) for HTN were 1.12 (0.93–1.35), 1.40 (1.17–1.69) and 1.50 (1.24–1.82), respectively. Results of the sensitivity analyses were robust. The ORs were generally consistent on subgroup analysis by sex, smoking status, systolic blood pressure and diastolic blood pressure. Multiple logistic regression models with restricted cubic splines showed a non-linear positive association between WWI and HTN (P_nonlinearity < 0.001).ConclusionThe highest WWI category was significantly associated with increased risk of HTN. Our findings may facilitate the development and promotion of obesity prevention strategies aimed at reducing the risk of HTN and provide evidence for healthcare policy in rural China.     

中医气郁质的研究进展

体质是在先天遗传和后天获得共同影响下形成的个体在形态结构和功能活动方面所固有的、相对稳定的特点,并且与心理性格具有相关性。其中气郁质的表现多与心理性格具有较大的相关性,同时由于当代社会的快速发展,各种危机和压力使年轻人成为气郁质的高发人群,因此探究气郁质的相关研究具有重大意义。本文通过对近些年来所发表的气郁质相关文献进行总结,重点从气郁质的人群分布调查研究、体病相关研究、调体干预研究以及实验室相关指标的研究四个方面进行分析阐述。最后对目前关于气郁质的研究中存在的优点和不足进行思考,并提出气郁质研究应在中医理论为指导的基础上,通过现代分子生物学实验或临床干预调体研究,揭示气郁质的本质和其量化诊疗标准,丰富气郁质的理论数据支持,促进中医体质学与多学科的交互发展。     

肾母细胞瘤MIB-1（Ki-67增殖指数）和p27kip1表达及与预后的关系

目的:探讨肾母细胞瘤MIB-1（Ki-67增殖指数）和细胞周期蛋白依赖性激酶抑制剂p27kip1的表达及与预后的关系。方法:经医院伦理委员会批准，连续纳入2008年1月至2013年8月在我院就诊的肾母细胞瘤患者样本作为研究对象，观察p27kip1和MIB-1阳性表达与患者临床特征的关系。结果:肿瘤组织中MIB-1阳性表达率高于正常肾组织，p27kip1阳性表达率低于正常肾组织，差异均有统计学意义（P＜0.05）。MIB-1和p27kip1表达与性别、年龄、病理分型、发病部位等均无相关性（P＞0.05），与临床分期存在相关性（P＜0.05）。MIB-1表达阳性患者中位生存时间低于阴性患者，而p27kip1表达阴性患者中位生存时间低于阳性患者（χ2=6.979、15.247，P=0.008、0.000）。结论:MIB-1表达增加和p27kip1表达降低与肾母细胞瘤的发生、发展、预后密切相关，临床应根据其表达情况进行针对性干预，以改善患者的预后。     

Arterial stiffness in women previously with preeclampsia from a semi-rural region of South Africa

Women with pre-eclampsia have an increased risk of cardiovascular disease later in life. The aim of the study was to establish the presence and pattern of arterial stiffness in women previously with pre-eclampsia from a semi-rural region of South Africa. This was a prospective longitudinal study which involved 36 previously pre-eclamptic women and 86 non-pregnant controls (NPC) who had a past history of non-complicated pregnancy. Maternal wave reflection (augmentation index) and carotid-femoral pulse wave velocity were assessed noninvasively, using applanation tonometry with the SphygmoCor device. Endothelial function was assessed by EndoPAT 2000 device; pneumatic probes were fitted to the index fingers; induced flow-mediated reactive hyperemia; the ratio of the readings before and after occlusion was then used to calculate the score, the reactive hyperemia index (RHI) as a measure of endothelial function.

Pulse wave velocity remained significantly higher in previously pre-eclamptic women than non-pregnant controls up to three months after delivery (p < 0.05), then it reduced to nonsignificant values. All blood pressure indices (central and brachial pressures), were higher in previously pre-eclamptic women as compared to nonpregnant controls up to one year postpartum.

Regional (aortic) arterial stiffness, though it persists for some time after delivery, is transitory in previously pre-eclamptic women from the rural Africa setting. However, their increase blood pressure is an indication of compromised arterial compliance in women previously with pre-eclampsia.
