The preventive role of wheat germ oil against sertraline‐induced testicular damage in male albino rats

Sertraline is an antidepressant medication used extensively in the therapy of depression. The present investigation was intended to estimate the actual protective role of wheat germ oil on sertraline‐caused testicular injury in albino rats. Sertraline (human therapeutic dose, 15.63 mg/kg) was orally administrated to rats for 28 successive days. Sertraline‐administered rats were concurrently supplemented with wheat germ oil (human therapeutic dose, 68.75 mg/kg) for 28 successive days. Sertraline administration induced an elevation in testicular DNA damage and acute testicular damage illustrated by the histopathological alterations including marked degeneration and necrosis of germ cells lining seminiferous tubules, as well as interstitial oedema, congestion of interstitial blood vessel. Wheat germ oil administration potentially mitigated the histopathological alterations of sertraline‐administered rats. Lipid peroxidation, oxidative stress biomarker, showed a significant elevation in testicular tissue of sertraline‐administered rats. Furthermore, glutathione content and catalase activity were decreased in testicular tissue of sertraline‐administered rats. Serum testosterone level was elevated in sertraline‐administered rats. Wheat germ oil significantly reduced lipid peroxidation of testicular tissue and improved the antioxidant defences. Finally, wheat germ oil has a preventive role against testicular damage induced by sertraline in rats probably via its potential to prevent reactive oxygen species.     

延续护理干预对慢性乙型肝炎患者抗病毒治疗依从性的影响观察

目的:分析延续护理干预对慢性乙型肝炎患者抗病毒治疗依从性的影响。方法:研究选取2017年1月~2017年12月某院肝二病区收治的112例乙型肝炎患者和2018年1月~2018年12月收治的98例乙型肝炎病毒患者作为研究对象,所有患者均进行抗病毒治疗,回顾性分析患者的病历资料。将2017年收治的112例患者作为常规组实施常规护理,将2018年收治的98例患者的作为研究组实施延续性护理,比较两组的护理效果。结果:研究组的治疗依从率为93.88%(92例),远高于常规组的77.68%(87例),两组数据比较存在统计学意义(P<0.05)。结论:延续性护理措施可以有效提高慢性乙型肝炎抗病毒治疗的依从性,可以在临床中推广使用。     

呼吸专科护士慢性呼吸疾病管理现状调查

目的调查呼吸专科护士慢性呼吸疾病管理现状,为提高慢性呼吸疾病的管理水平提供参考。方法依据《中国成人慢性呼吸疾病患者护理管理指南》设计调查问卷,对重庆、四川、贵州、陕西、河北、湖北、海南7省市的205名呼吸专科护士进行问卷调查。结果呼吸专科护士慢性呼吸疾病管理总分为(140.72±23.90)分。慢性呼吸疾病管理得分最低的3个条目有评估工具应用、个性化管理计划的实施、慢阻肺随访的次数及指导哮喘患者使用峰流速仪;呼吸专科护士所在单位慢性呼吸疾病管理平台建设均低于50%。结论呼吸专科护士慢性呼吸疾病管理处于中等偏下水平,评估是慢性呼吸疾病管理的薄弱点。需加强呼吸专科护士专业能力培养,规范慢性呼吸疾病全程管理,强化医院平台建设等,提高慢性呼吸疾病的管理水平。     

基于BGP、TGF-β1的表达探究蛇床子素对去卵巢致骨质疏松大鼠的作用

目的观察蛇床子素对去卵巢致骨质疏松大鼠的影响。方法选取3月龄雌性SD大鼠30只,随机分为蛇床子素组(A组)、模型对照组(B组)、假手术组(C组),各10只。A、B 2组摘除卵巢构建去势大鼠骨质疏松模型,C组仅进行手术、不摘除卵巢。造模成功后,分别给予相应药物灌胃,连续给药12周,处死。然后测量骨密度,检测治疗后血清BGP、TGF-β1、钙指标。结果B组大鼠股骨骨密度较C组明显降低(P<0.05);经12周治疗,A组股骨骨密度较B组明显升高(P<0.05)。与C组比较,B组大鼠血清中BGP含量升高、TGF-β1降低(P<0.05);与B组比较,A组大鼠血清中BGP降低、TGF-β1含量升高(P<0.05)。与C组比较,B组大鼠血清Ca水平明显降低(P<0.05);与B组比较,A组大鼠血清Ca水平明显升高(P<0.05)。差异均有统计学意义。结论蛇床子素能够有效通过调节大鼠体内激素分泌改善去卵巢大鼠的骨代谢异常,提高骨密度,对骨质疏松症起到一定的防治作用。

Peripheral whole blood FOXP3 TSDR methylation: a potential marker in severity assessment of autoimmune diseases and chronic infections

Immune dysregulation is a cardinal feature of autoimmune diseases and chronic microbial infections. In particular, regulatory T cells are downregulated in autoimmune diseases while upregulated in chronic microbial infections. FOXP3 is the master regulator of Treg development. Treg-specific demethylated region (TSDR) is a highly conserved locus on the FOXP3 gene that is fully demethylated in natural Tregs but methylated in effector T cells. In our study, we used high resolution melt-polymerase chain reaction (HRM-PCR) to determine the FOXP3 TSDR methylation status in autoimmune diseases and chronic microbial infections. We found that FOXP3 TSDR to have the highest mean melting temperature (highly methylated) in active SLE patients compared to all the other groups (p?<?0.001). The psoriasis group also had a significantly high mean melting temperature (78.62?±?0.20) when compared with the inactive SLE group (78.49?±?0.29, p?<?0.05) and control group (78.44?±?0.25, p?<?0.01). There was no significant difference in melting temperature between inactive SLE and healthy controls. Disease activity in SLE was directly associated with methylation of the FOXP3 TSDR. On the other hand, patients with chronic microbial infections had significantly lower FOXP3 TSDR mean melting temperature (demethylated) when compared with healthy controls (78.28?±?0.21 vs 78.44?±?0.25, p?<?0.05). Our results suggest that the use of HRM-PCR to detect FOXP3 TSDR methylation status is a reliable and easy method to predict natural regulatory T cell levels in peripheral blood in different disease conditions. Determining FOXP3 TSDR methylation status can be a useful tool in diagnosis, and monitoring the severity of autoimmune diseases and chronic microbial infections.
