脑卒中患者恐惧疾病进展的研究现状

脑卒中患者在面对复杂的治疗期、漫长的康复期及难以预测的病情变化时容易产生对疾病或疾病进展的恐惧。恐惧疾病进展会损害脑卒中患者的身心健康和社会功能,最终影响患者的康复和预后。从恐惧疾病进展的定义、测量工具、国内外研究现状及影响因素几个方面进行综述,为临床护理人员深入了解脑卒中患者恐惧疾病进展现状、开展相关护理实践和临床研究提供依据。     

维生素D在孤独症谱系障碍中作用的研究进展

孤独症谱系障碍(ASD)是影响儿童健康的严重公共问题之一,以社交沟通障碍、兴趣或活动范围狭窄以及重复刻板行为为特征。近年来越来越多的研究显示,ASD患儿维生素D(VitD)水平明显低于同龄健康儿童,VitD缺乏可能与ASD的发病机制相关。本文就VitD与ASD的相关研究进行综述。     

口服异维A酸治疗痤疮的研究

口服异维A酸是目前临床上最为有效的抗痤疮药物,可同时作用于痤疮发病的4个主要环节。异维A酸在皮脂腺细胞内独特的分子作用机制使其具有强大的抑制皮脂腺分泌活性,近来其对痤疮免疫和炎症反应的拮抗作用也越来越受到重视。口服异维A酸主要用于治疗结节囊肿型重度痤疮以及其他治疗效果不好的中、重度寻常痤疮,使用剂量应根据患者的体重、疗效、依从性及不良反应进行综合判定。小剂量[0.25~0.5 mg/(kg·d)]治疗可以显著降低药物的不良反应及增加患者依从性;累积剂量达60~120 mg/kg可以明显降低痤疮复发率。异维A酸不良反应大多以皮肤黏膜为主要表现,严重不良反应罕见,致畸是其最严重的不良反应。口服异维A酸能快速改善痤疮皮损,有效预防痤疮瘢痕形成,改善患者生活质量。

目的探讨足趾移植长手指全形再造手术的临床疗效。方法自2015年6月至2019年6月,对16例因外伤致手指缺损患者采用足趾移植长手指全形再造术,术后评估供区及受区的感觉功能、运动功能及外观形态,分析指甲畸形及增生性瘢痕的发生情况,并记录术后发生感染、血肿、皮片坏死及供区愈合不良等情况;通过调查问卷的方式分析患者的满意度。结果所有患者术后获随访1~12个月,其中2例受区发生感染,1例受区皮片边缘发生坏死,经换药后予以缓解;其余患者的供、受区均未出现长时间的痛疼感觉,受区感觉功能恢复达87.50%,受区运动功能恢复均较满意,手指外形基本满意。供区感觉受影响者2例,运动功能受限者1例,外形一般者2例。所有患者无指甲畸形及增生性瘢痕发生;满意者1例,基本满意者14例,不满意者1例。结论采用足趾移植长手指全形再造手术,基本可以满足患者及医师对于缺损手指进行完美修复的目标。     

Effect of Electroacupuncture on Spermatogenesis in Rats with Oligozoospermia of Insufficiency of Shen (Kidney) Essence Syndrome

Objective: To assess the effect of electroacupuncture(EA) on expression of cytoskeletal proteins from Sertoli cells(SCs) and spermatogenesis in rats with oligozoospermia of insufficiency of Shen(Kidney)essence syndrome(OIKES).Methods: Twenty healthy male Sprague-Dawley rats were randomly assigned to four groups using a random number table: control,tripterygium glycosides(TG) treatment,sham and EA groups(n=5 in each group).A rat model of OIKES was established by oral gavage with TG.The EA group was treated with TG and received EA at Shenshu(BL 23) and Zusanli(ST 36) acupoints for 20 min,once daily for 30 days,while the sham group received EA at identical acupoints with skin penetration without stimulation.After 30 days,the ?nal body weight and coef?cients for the testis and epididymis were calculated and sperm parameters were measured.Immunohistochemical analyses were performed to detect expression of vimentin and α-tubulin in SCs and proliferating cell nuclear antigen(PCNA) immunoreactivity in germ cells.Apoptosis in germ cells was quanti?ed by the transferase biotin-dUTP nick end labeling assay.Results: Compared with the control group,the final body weight and testis/epididymis coefficients of rats in the TG-treated group were not significantly different,but the sperm count and motility were lower(P0.05).Expressions of vimentin and α-tubulin were also signi?cantly weaker(P0.01).The PCNA immunoreactivity of germ cells was decreased(P=0.059),whereas the apoptotic index of germ cells was increased signi?cantly(P0.01).In contrast,EA at BL 23 and ST 36 acupoints signi?cantly improved the ?nal body weight as well as the sperm count,concentration and motility(P0.01 or P0.05).EA increased expression of vimentin and α-tubulin in SCs markedly,and signi?cantly enhanced PCNA immunoreactivity with decreased apoptosis in germ cells(P0.01 or P0.05).Conclusions: EA at BL 23 and ST 36 acupoints has protective effects on spermatogenesis in rats with OIKES.This effect seems to be achieved by attenuating TG-induced disruption of cytoskeletal protein in SCs.     

体外受精胚胎移植中异常受精的原因分析

当前，体外受精-胚胎移植技术(in vito fertilization,IVF-ET)是治疗不孕不育问题的重要手段之一。1978年世界上第一例试管婴儿自英国诞生以来，已有成千上万的不孕不育夫妇通过这项技术获得了后代，随这项技术的发展，促排卵技术、配子的体外受精技术、胚胎的体外培养技术不断得到改善，但目前仍有许多夫妇因为各种原因导致不能受孕，受精失败就是原因之一。有文献指出：夫妇双方在排除男性不育的因素之后，传统IVF-ET的受精失败率仍然在2-3％[1]，受精失败的模式包括：卵子完全不受精及卵子的异常受精。临床上卵子完全不受精或受精率低时，可以通过补救ICSI来进行挽救，但卵子异常受精情况的发生目前还无法进行挽救，这导致卵子的利用率低下，增加了患者的经济与精神负担。因此，如何预防和降低异常受精的发生将成为改善IVF-ET总体结局的重要环节,本文拟将体外受精过程中出现的可能影响受精结局的问题进行逐一探讨。     

Atypical cutaneous γδ T cell proliferation with morphologic features of lymphoma but with clinical features and course of PLEVA or lymphomatoid papulosis

Reactive lymphoid infiltrates of the skin composed predominantly of gamma‐delta (γδ) T cells are not well described in the literature. Herein we report a case of an otherwise healthy 4‐year‐old male who presented with a waxing and waning papular rash characterized by small, discrete crusted papules spread across his trunk, face and extremities. Clinical evaluation revealed no evidence of systemic disease. Microscopic examination revealed a dermal, perivascular infiltrate of highly atypical lymphocytes with a γδ T cell phenotype, worrisome for primary cutaneous γδ T cell lymphoma. The clinical course, however, was that of a reactive condition and prompted consideration of a diagnosis of pityriasis lichenoides et varioliformis acuta (PLEVA) and lymphomatoid papulosis (LyP). In many ways, this case defies current classification schemes and seems to expand the spectrum of reactive γδ T cell infiltrates of the skin.
