同型半胱氨酸对高血压患者脑卒中复发风险的影响

目的探讨高血压合并脑卒中患者的血浆同型半胱氨酸（Hcy）水平与其他危险因素对于脑卒中复发的影响。 方法分析徐州市中心医院心内科和徐州医科大学附属医院神经外科自2012年5月至2013年12月收治的1623例高血压脑卒中患者的基线资料，中位随访4.9年，根据随访事件中是否发生脑卒中分为复发组（312例）与未复发组（1311例）。Kaplan-Meier生存分析比较不同危险因素脑卒中复发率的差异，单因素与多因素Cox回归模型分析影响脑卒中复发的独立危险因素，以及危险因素之间的交互作用。 结果复发组年龄、空腹血糖、Lg Hcy的水平，以及糖尿病、房颤的患病率均高于未复发组（P<0.05）。Kaplan-Meier生存分析显示，糖尿病、房颤、年龄≥60岁、空腹血糖≥7.0 mmol/L、Hcy≥15 μmol/L的脑卒中复发率明显升高（Log-rank检验，P<0.05）。多因素Cox回归模型分析显示，高龄、Lg Hcy水平升高，以及房颤、糖尿病是脑卒中复发的独立危险因素。Lg Hcy分别与糖尿病、空腹血糖、年龄存在交互作用。 结论血浆Hcy水平升高既是高血压合并脑卒中患者卒中复发的独立危险因素，又通过与糖尿病、高龄、空腹血糖水平升高的交互作用显著增加脑卒中复发风险。     

不可切除胃癌转化治疗的研究进展

胃癌在全国范围内是发病率最高的恶性肿瘤之一，在癌症相关死亡原因中排名第三。目前外科手术仍然是胃癌获得根治性治疗的主要手段，但是其中有30%~40%的进展期胃癌患者在初诊时就失去了根治手术的机会，因此不可切除胃癌转化为可切除胃癌是患者获得"治愈"的最佳选择。随着近些年来新型药物的出现、治疗手段的多样化及多学科诊治模式的发展，"转化治疗"的理念应运而生，从而延长患者生存时间并提高其生活质量。本文就不可切除胃癌的治疗现状与进展、"转化治疗"的应用等进行综述。

Unexpected Return for Follow-up During the First Year of Multidisciplinary Care May Be Predictive of Rapid Deterioration of Renal Function

Multidisciplinary predialysis education and team care (MDC) may slow the decline in renal function in patients with chronic kidney disease (CKD). However, associations between unexpected return during MDC and progression of renal dysfunction have not been characterized in patients with CKD. Our study aimed to determine the association between exacerbation of renal dysfunction and the frequency of unexpected return during follow-up.A total of 437 patients with CKD receiving multidisciplinary care between January 2009 and June 2013 at the Shin-Kong Wu Ho-Su Memorial Hospital were included in this retrospective observational cohort study, and multiple imputations were performed for missing data. The predictor was the frequency of unexpected return for follow-up during the first year after entering MDC. Main outcome was monthly declines in estimated glomerular filtration rates (eGFR). Moreover, the demographic data, comorbidities, history of medication, and routine laboratory data for patients with CKD were collected.Among all patients, 59.7% were male, the mean age at initiation of MDC was 69.4 ± 13.2 years, and the duration of follow-up was 21.4 ± 3.3 months. The subjects were divided into 2 groups according to frequencies of follow-up (≤4 and > 4 visits) during the 1st year of MDC. The patients with CKD were regularly followed up every 3 months as a part of MDC in our hospital, and patients who returned for more than 4 follow-up visits were included in the unexpected return group. In crude regression analyses, unexpected return was significantly associated with higher monthly declines of eGFR (β = 0.092, 95% confidence interval, 0.014–0.170). This association remained after adjustments for multiple variables, and subgroup analyses of unexpected return showed that male gender, older age, CKD stage 1 to 3, hypertension, history of coronary artery disease, and use of renin–angiotensin system blockade were significantly associated with declines in renal function.In conclusion, unexpected return for follow-up during the 1st year of MDC was significantly associated with the deterioration of renal function.     

血清谷丙转氨酶水平与不同性别2型糖尿病患病的关系

目的 探讨血清谷丙转氨酶（ALT）与新诊2型糖尿病（T2DM）患病风险之间的关联，为T2DM的防治提供科学依据。方法 采用4阶段分层随机抽样的方法选取2006年和2009年参与青岛糖尿病预防项目的研究对象男性3 012例、女性4 422例，采用Pearson相关检验分析不同性别ALT与FPG、2 h PG的相关性，并利用多因素logistic回归分析ALT与新诊T2DM患病的关系。结果 男性中，ALT与空腹血浆血糖（FPG）、餐后2 h血浆血糖（2 h PG）的Pearson相关系数分别为0.088、0.080（均P＜0.01）；多因素logistic回归显示，在调整了年龄、BMI、糖尿病家族史、城乡、教育、婚姻、收入、吸烟及饮酒状况等混杂因素后，ALT的第4分位（Q4）组新诊T2DM患病风险是第1分位（Q1）组的1.832倍（OR = 1.832，95% CI:1.324～2.534，P＜0.01）。女性中，ALT与FPG、2h PG的Pearson相关系数分别为0.065、0.108（均P＜0.01）；多因素logistic回归显示，在调整了年龄、BMI、糖尿病家族史、城乡、教育、婚姻、收入、吸烟及饮酒状况等混杂因素后，ALT的第4分位（Q4）组新诊T2DM患病风险是第1分位（Q1）组的1.445倍（OR = 1.445，95% CI:1.087～1.919，P＜0.05）。结论 在男、女性人群中，ALT水平升高与T2DM患病相关，且这种相关性不受年龄、BMI、糖尿病家族史等的影响。     

家长对小学生近视的知信行分析

目的 了解保定市小学生家长关于小学生近视知信行的相关现状及影响因素,制定有效干预措施,为预防儿童青少年近视提供有力依据。方法 运用分层整群随机抽样的方法,抽取保定市某小学一年级至六年级766名学生家长进行问卷调查。结果 小学生家长用眼卫生相关知识总正确率为64.90%。家长年龄越大、文化程度越高以及自身近视的家长掌握小学生近视的相关知识越多。家长年龄越大,督导孩子健康用眼的行为越易发生(P=0.027,OR=0.169)。结论 应多渠道对学生家长进行健康教育,为控制和预防小学生近视的发生与发展构建以家庭为主的第一道防线。     

急诊住院医师的教学查房模式

教学查房是床旁教学的一种重要手段,对住院医师进行教学查房能够有效提高住院医师的岗位胜任力和职业能力,培养急诊住院医师的急诊临床思维。近年来由于国家住院医师规范化培训改革在不断深入,对急诊住院医师的教学查房引起了人们的高度关注,然后在实际的急诊住院医师的教学查房中却还存在着诸多问题,教学查房与日常的临床查房概念混淆、教学查房准备不充分、教学查房目的不明确以及教学查房的互动性不强都严重影响了教学查房的质量。因此需要积极探究急诊住院医师的教学查房的有效模式,从而不断提升住院医师的临床实践能力。

Necroptotic TNFα-Syndecan 4-TNFα Vicious Cycle as a Therapeutic Target for Preventing Temporomandibular Joint Osteoarthritis

Temporomandibular joint osteoarthritis (TMJOA) is a chronic degenerative disease for which the underlying mechanism still remains unclear. Compared with apoptosis and autophagy, necroptosis causes greater harm to tissue homeostasis by releasing damage-associated molecular patterns (DAMPs). However, the role of necroptosis and downstream key DAMPs in TMJOA is unknown. Here, rodent models of TMJOA were established by the unilateral anterior crossbite (UAC). Transmission electron microscopy (TEM) and immunohistochemistry of receptor interacting protein kinase 3 (RIPK3)/phosphorylation of mixed lineage kinase domain-like protein (pMLKL) were conducted to evaluate the occurrence of necroptosis in vivo. The therapeutic effects of blocking necroptosis were achieved by intra-articularly injecting RIPK3 or MLKL inhibitors and using RIPK3 or MLKL knockout mice. In vitro necroptosis of condylar chondrocyte was induced by combination of tumor necrosis factor alpha (TNFα), second mitochondria-derived activator of caspases (SMAC) mimetics and carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]- fluoromethylketone (z-VAD-fmk). The possible DAMPs released by necroptotic chondrocytes were screened by quantitative proteomics and blocked by specific antibody. Translucent cytosol, swollen organelles, and ruptured cell membranes, features of necroptosis, were frequently manifested in chondrocytes at the early stage of condylar cartilage degeneration in TMJOA, which was accompanied by upregulation of RIPK3/pMLKL. Inhibiting or knocking out RIPK3/MLKL significantly prevented cartilage degeneration. DAMPs released by necroptotic condylar chondrocytes, such as syndecan 4 (SDC4) and heat shock protein 90 (HSP90), were verified. Furthermore, blocking the function of SDC4 significantly attenuated the expression of TNFα in cartilage and synovium, and accordingly increased cartilage thickness and reduced synovial inflammation. Thus, the necroptotic vicious cycle of TNFα-SDC4-TNFα contributes to cartilage degeneration and synovitis, and can serve as a potential therapeutic target for treating TMJOA. © 2022 American Society for Bone and Mineral Research (ASBMR).
