A case-control study of paternal and maternal age as risk factors in mood disorders

Objective: Advanced parental age might constitute a risk factor for various disorders. We tested whether this concerns also mood disorder patients.

Methods: The study included 314 subjects (42 bipolar-BD patients; 21 manics and 21 depressives, 68 unipolar-UD, and 204 normal controls-NC). Analysis of Covariance (ANCOVA) and the calculation of the Relative Risk (RR) and the Odds Ratio (OR) were used for the analysis.

Results: Paternal age differed between NC and UD patients (29.42?±?6.07 vs. 32.12?±?5.54; p?=?.01) and manics (29.42?±?6.07 vs. 35.00?±?5.75; p?=?.001) and maternal age between NC and manics (25.46?±?4.52 vs. 31.43?±?4.75; p?<?.001) and manic and UD (31.43?±?4.75 vs. 26.75?±?6.03; p?=?.002). The RR and OR values suggested that advanced parental age constitutes a risk factor for the development of mood disorders.

Conclusions: In a non-dose dependent and gender-independent, advanced parental age constitutes a risk factor for the development of BD with index episode of mania (probably manic predominant polarity); only advanced paternal age constitutes a risk factor for the development of UD and BD with index episode of depression (probably depressive predominant polarity). This is the first study suggesting differential effect of advanced parental age depending on predominant polarity of BD.     

糖尿病黄斑水肿患者病变程度与脉络膜厚度的关系

目的　利用频域光学相干断层扫描深度增强（enhanced depth imaging spectral domain optical coherence tomography，EDI SD-OCT）观察糖尿病黄斑水肿（diabetic macular edema，DME）患者脉络膜厚度（choroidal thickness，CT）的变化及结构特点，探讨DME病变程度与CT的关系。方法　纳入2型糖尿病患者共123例204眼，其中69眼诊断为DME（DME组），135眼无黄斑水肿为对照组。DME眼依据OCT形态学特点进一步分为视网膜弥漫性增厚（diffuse retinal thickness，DRT）型（34眼）、黄斑囊样水肿（cystoid macular edema，CME）型（19眼）和浆液性视网膜脱离（serous retinal detachment，SRD）型（16眼），利用EDI-OCT分别测量黄斑中心凹下CT和以黄斑为中心上、下、鼻、颞500 μm、1000 μm、1500 μm、2000 μm处CT。结果　DME组黄斑中心凹下CT为（326.72±90.15）μm，对照组为（320.17±106.46）μm，两组之间无统计学差异，但黄斑中心凹下CT与视网膜厚度间具有明显正相关关系（r=0.270，P=0.025）。DME亚型CT分别为:DRT型（303.94±81.47）μm、CME型（304.42±73.98）μm和SRD型（401.63±88.80）μm，SRD型CT明显高于其他亚型（P<0.05），此外，SRD型的周边CT同样呈现均匀一致的增厚；鼻侧CT从500 μm至2000 μm呈距离敏感性降低（P<0.05），但SRD型鼻侧CT降低幅度明显变缓（P=0.195）。结论　SRD型黄斑水肿患者CT在中心凹下及周边部均显著增厚，CT与DME病变程度之间有一定相关性。     

Use of Dolutegravir for Antiretroviral Therapy for Women of Childbearing Age

The purpose of this article is to offer an update on the use of antiretroviral therapy (ART) for HIV among women of childbearing age. We focus specifically on the use of dolutegravir (DTG) because of a recently identified potential safety issue related to neural tube defects in the fetuses of women who used DTG at the time of conception. Nurses and advanced practice registered nurses should engage in shared decision-making processes for reproductive life planning with women of childbearing age who are living with or are at risk for HIV. During these processes, exploration of the full range of ART regimens is essential. Consistent and reliable contraception is necessary with the use of DTG because it is not recommended in the first trimester of pregnancy.     

沙参麦冬汤加减对阴虚肺热证肺炎支原体肺炎恢复期患者免疫炎症反应的影响

目的:观察沙参麦冬汤加减对肺炎支原体肺炎恢复期患者阴虚肺热证的疗效及对免疫炎症反应的调节作用。方法:将148例患者按随机数字表法分为对照组和观察组各74例。研究期间对照组脱落、失访2例,剔除3例完成70例;观察组脱落、失访4例,完成71例。两组患者均口服阿奇霉素片,10 mg·kg~(-1)·d~(-1),连服3 d;和匹多莫德颗粒剂,0.4～0.8 g/次,2次/d;和氨溴特罗口服溶液,2.5～15 mL/次,2次/d。对照组口服养阴清肺口服液,5～10 mL/次,2～3次/d;观察组内服沙参麦冬汤加减,1剂/d。两组疗程均为7 d。进行治疗前后咳嗽症状评分和咳嗽视觉模拟评分(VAS);记录咳嗽、肺部湿啰音,咯痰消失时间和胸片复常时间;进行治疗前后阴虚肺热证评分和莱塞斯特咳嗽问卷(LCQ)评分;检测治疗前后T淋巴细胞亚群(CD3+,CD4+,CD8+和CD4+/CD8+)和白细胞介素-6(IL-6),IL~(-1)0,肿瘤坏死因子-α(TNF-α),P物质(SP),降钙素原基因相关肽(CGRP)水平;进行治疗后安全性评价。结果:观察组疾病疗效总有效为95.77%(68/71),优于对照组的82.86%(58/70)(χ2=6.186,P0.05);观察组患者咳嗽症状积分和VAS评分均明显低于对照组(P0.01);观察组患者LCQ量表各维度评分和LCQ总分均高于对照组(P0.01);观察组患者咳嗽、肺部湿啰音、咯痰消失时间及胸片复常时间均短于对照组(P0.01);观察组CD3+,CD4+,CD4+/CD8+均高于对照组(P0.01),CD8+低于对照组(P0.01);观察组血清IL-6,IL~(-1)0,TNF-α水平和痰液中SP和CGRP水均低于对照组(P0.01)。结论:在西医常规治疗的基础上,采用沙参麦冬汤加减内服治疗MPP恢复期阴虚肺热证患者,可减轻咳嗽程度,缩短病程,改善了生活质量,提高了细胞免疫功能,减轻了炎性损伤,降低了咳嗽敏感性,有较好的临床疗效,且使用安全。     

腰椎间盘突出症动物模型的研究进展

近年来,腰椎间盘突出症发病率逐渐增高,由于动物模型对于阐明疾病发病机制及评估新的治疗方法具有重要作用,越来越多的学者开始研究如何建立合适的、能够更好地模拟人类腰椎间盘突出的动物模型。近期的研究多选用包括大鼠、兔、羊、猪等动物作为实验对象,通过物理或化学方式直接损伤其椎间盘或神经根,或通过限制实验动物的行为动作、改变其饲养环境以及性别年龄导致的生理因素等方式诱导其出现椎间盘退变。各种造模方法均有其特点及局限性,适用于不同情况,有必要继续完善。
