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.

肝脏子宫内膜异位症一例

肝脏子宫内膜异位症是以肝内存在异位子宫内膜为特征的一种罕见子宫内膜异位症类型,因其缺乏典型临床症状且影像学诊断困难,易被误诊,组织学检查目前仍是肝脏子宫内膜异位症诊断的金标准。现报告1例海军军医大学第三附属医院收治的患者,反复经期右上腹疼痛,经超声检查发现右肝占位性病变,术后病理证实为肝脏子宫内膜异位症。     

PMA对U937细胞CD18mRNA表达的诱导作用及其机制

目的:研究PMA对CD18mRNA表达的促进作用及机制。方法:选用PMA刺激下的U937细胞为实验模型,运用定量RT-PCR方法检测U937细胞CD18mRNA的表达水平。结果:PMA具有浓度和时间依赖性地诱导U937细胞CD18mRNA表达的作用,这种作用能分别被PKC、NF-κB抑制剂所抑制,但不能被转录因子AP-1抑制剂所抑制。结论:PMA能激活细胞的PKC,进而通过其后的信号转导通路促进CD18mRNA的表达,转录因子NF-κB为PMA刺激下的U937细胞CD18基因转录所必需,而AP-1则相反。

肺癌高危人群癌症防治核心知识认知情况调查

目的 探讨肺癌高危人群对癌症防治核心知识认知情况并对其影响因素进行分析。方法 以2017年3月至2019年12月在上海市某医院胸外科完成肺癌高危人群筛查并判断为肺癌高危人群的居民为研究对象,开展癌症防治核心知识知晓情况调查,采用描述流行病学分析方法对癌症防治核心知识掌握情况进行分析,并采用单、多因素分析方法对知识掌握影响因素进行分析。结果 共纳入肺癌高危人群416例,年龄40~72岁,男性269例,女性147例,分别占64.66%、35.34%。癌症防治核心知识知晓326例,知晓率为78.4%。知晓率最高的为“体检或癌症筛查有利于早期发现癌症”、“癌症无传染性;癌症早期可无明显症状;癌症检查价格并非越高效果越好”、“戒烟有利于预防肺癌”,知晓率分别为92.79%、92.31%、90.38%。知晓率最低的为“适龄生育、母乳喂养、多进行身体活动、保持合适体重、少饮酒和定期体检有利于预防乳腺癌”、“肺癌早期筛查的有效方法”、“导致癌症发病的高风险因素”,知晓率分别为50.24%、37.98%、34.86%。二分类Logistic回归分析结果显示,年龄60~72岁（OR=0.418）、文化程度为大专及以上（OR=2.309）、职业类型为医疗卫生行业（OR=4.121）是肺癌高危人群癌症防治核心知识知晓的影响因素。结论 肺癌高危人群防癌认知的总体知晓情况较好,但还应针对年龄较大、文化程度较低及非医疗卫生行业人群进一步加强癌症防治宣传,不断提高广大居民群众的防癌知识认知水平。

Junctional adhesion molecule-like protein as a novel target for kaempferol to ameliorate lung adenocarcinoma

ObjectiveAlthough there have been improvements in targeted therapy and immunotherapy, the majority of lung adenocarcinoma (LUAD) patients still lack effective therapies. Consequently, it is urgent to screen for new diagnosis biomarkers and pharmacological targets. Junctional adhesion molecule-like protein (JAML) was considered to be an oncogenic protein and may be a novel therapeutic target in LUAD. Kaempferol is a natural flavonoid that exhibits antitumor activities in LUAD. However, the effect of kaempferol on JAML is still unknown.MethodsSmall interfering RNA was used to knockdown JAML expression. The cell viability was determined using the cell counting kit-8 assay. The proliferation of LUAD cells was evaluated using the 5-ethynyl-2′-deoxyuridine incorporation assay. The migration and invasion of LUAD cells were evaluated by transwell assays. Molecular mechanisms were explored by Western blotting.ResultsJAML knockdown suppressed proliferation, migration and invasion of LUAD cells, and JAML deficiency restrained epithelial-mesenchymal transition (EMT) via inactivating the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway. Using a PI3K activator (740Y-P), rescue experiments showed that phenotypes to JAML knockdown in LUAD cells were dependent on the PI3K/AKT/mTOR pathway. Kaempferol also inhibited proliferation, migration and invasion of A549 and H1299 cells and partially suppressed EMT through the PI3K/AKT/mTOR pathway. Knockdown of JAML ameliorated the inhibitory effect of kaempferol on LUAD cells. Kaempferol exerted anticancer effects by targeting JAML.ConclusionJAML is a novel target for kaempferol against LUAD cells.Please cite this article as: Wu Q, Wang YB, Che XW, Wang H, Wang W.
