Serum Neurotensin: An Objective Mirror to Acne-induced Quality of Life and Psychological Impairment

BackgroundAcne is a multifactorial disorder, and stress potentially plays a role in its pathogenesis.ObjectivesWe aimed to assess the serum levels of neurotensin in patients with acne vulgaris (AV) and investigate the relationship of these levels to quality of life (QoL), depression, anxiety, and stress.MethodsThe study included 60 patients with AV classified into mild (n=20), moderate (n=20), and severe (n=20) groups and 20 healthy, age-matched, sex-matched, and body mass index (BMI)-matched individuals in a control group. Patient QoL was assessed using the Dermatology Life Quality Index (DLQI). Each participant completed the Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS-10). Serum levels of neurotensin were measured with enzyme-linked immunosorbent assay (ELISA).ResultsNeurotensin levels and scores from the three questionnaires were significantly higher among the patients with AV than the control subjects. They were also significantly elevated in patients with post-acne scars and hyperpigmentation and in those with severe acne.ConclusionIt is well known that acne greatly impacts QoL and might be associated with depression, anxiety, and stress. Further, serum neurotensin could be a promising marker to objectively evaluate the psychosocial impact of AV.     

温针灸联合放血疗法对痤疮患者皮损程度、DLQI评分及复发率的影响

目的观察温针灸联合放血疗法对痤疮患者皮损程度、皮肤病生活质量指数(dermatology life quality index,DLQI)评分及复发率的影响。方法 120例湿热型痤疮患者随机分为观察组和对照组,每组60例。对照组采用放血疗法,观察组在对照组基础上联合温针灸治疗。观察两组患者治疗前后皮损程度、DLQI评分、中医症候评分变化,比较两组的临床疗效、不良反应发生率及复发率。结果观察组总有效率显著高于对照组(P<0.05)。两组治疗后皮损个数显著减少(P<0.05),且观察组皮损个数少于对照组(P<0.05),皮损减少率大于对照组(P<0.05)。治疗后两组DLQI评分、中医症候评分均显著降低(P<0.05),且观察组低于对照组(P<0.05)。两组不良反应发生率比较,差异无统计学意义(P>0.05)。治疗组复发率显著低于对照组(P<0.05)。结论温针灸联合放血疗法治疗湿热型痤疮疗效佳,不良反应率低,复发率低,疗效稳定。     

Perspectives on the International Recommendations for the Diagnosis and Treatment of Polycystic Ovary Syndrome in Adolescence

Recommendations have been provided for the diagnosis and therapy of polycystic ovary syndrome in adolescence from 3 international expert conferences 2015-2018. Despite agreement about essentials, differences among details of these recommendations have engendered confusion. This commentary provides perspective about the agreements and disagreements among these recommendations and how these recommendations relate to other guidance. It concludes with practice suggestions that align with these recommendations.     

PsAPASH: a rare and recent autoinflammatory syndrome associated with hidradenitis suppurativa

Hidradenitis suppurativa is a chronic inflammatory skin disease, which affects 1% of the population, being more common in young, obese and smokers, and mainly affects armpits and groin, with formation of pustules, nodules, abscesses, scars and fistulas. Recently, its association with other autoimmune diseases such as psoriasis, psoriatic arthritis, pyoderma gangrenosum, pyogenic arthritis and ulcerative colitis have been reported. These associated forms are usually resistant to standard treatment, with immunobiologicals as promising therapy. The case of a rare form of association is reported, with only one case previously described in the literature: psoriasis arthritis, pyoderma gangrenosum, acne and hidradenitis suppurativa.     

加味黑布膏对大鼠耳廓复合痤疮模型局部组织IL-2及EGF的影响

目的通过观察加味黑布膏对大鼠耳廓复合痤疮模型IL-2及EGF的影响,研究加味黑布膏对大鼠痤疮的干预机制。方法按随机数字表法将72只雌雄各半的Wistar大鼠平均分为6组,分别是:空白组、模型组、加味黑布膏高、中、低剂量组以及阳性对照组。除空白组外用Kligman法对大鼠耳廓进行造模,21 d后,随机抽取4只进行病理切片观察,提示造模成功后开始外用药物,空白组和模型组不给予药物治疗,黑布膏低、中、高剂量组分别给予不同剂量的加味黑布膏,外用1次/d,阳性对照组给予0.025%的维A酸乳膏,给药1次/d,连续用药4周,4周后对大鼠进行局部组织采样,并采用ELISA法检测样品中IL-2以及EGF的含量。结果经4周治疗后各组局部组织中IL-2以及EGF较模型组均有所下降(P<0.05),加味黑布膏中、低剂量组中所测因子与阳性对照组比较差异无统计意义(P>0.05),高剂量组与阳性对照组比较差异有统计学意义(P<0.01)。结论加味黑布膏治疗痤疮疗效明确,可能与加味黑布膏降低局部组织中IL-2及EGF有关。

痤疮相关基因多态性的研究进展

痤疮是一种可能与多基因遗传有关的累及毛囊皮脂腺的炎症性皮肤病,发病机制复杂,目前尚未完全阐明.已有研究表明,某些基因的单核苷酸多态性可能与痤疮易感性相关,如SELL基因、RETN基因、DDB2基因、MYC基因、转化生长因子通路相关基因、胰岛素样生长因子1基因等.从炎症相关基因多态性、推激素受体相关基因多态性、转化生长因子β通路相关基因多态性及胰岛素受体相关基因多态性4个方面,探讨痤疮相关基因多态性的研究进展.深入探索痤疮相关基因多态性对基因靶向药物的研发有重要意义.
