Green tea extract (GTE) has been studied for the treatment of acne based on its anti‐inflammatory/antioxidant properties. This systematic review and meta‐analysis aimed to examine the effects of GTE on acne. Electronic databases, including PubMed, Embase, and the Cochrane Library were systematically searched up to August 2019. The effect size of acne lesion counts is presented as mean differences and 95% confidence intervals (CIs). Five randomized‐controlled studies were included in the meta‐analysis (N; experimental = 125, control = 122). GTE significantly reduced the number of inflammatory lesions (?9.38; 95% CI: ?14.13 to ?4.63). In subgroup analysis, topical GTE application significantly reduced the inflammatory lesion counts (?11.39; 95% CI: ?15.91 to ?6.86) whereas oral GTE intake showed minimal effect (?1.40; 95% CI: ?2.50 to ?0.30). Although GTE did not significantly reduce the number of non‐inflammatory lesions (?21.65; 95% CI: ?47.52 to 4.22), when stratified by the route of admission, non‐inflammatory acne lesions were significantly reduced by topical GTE application (?32.44; 95% CI: ?39.27 to ?25.62) but not with oral GTE administration (0.20; 95% CI: 0.00 to 0.40). This systematic review and meta‐analysis suggest that topical GTE application is beneficial for the treatment of acne without causing significant adverse events while oral GTE intake has limited effects. Further high‐quality clinical trials are warranted.  相似文献

Background: Acne is a common and chronic inflammatory dermatosis of sebaceous gland units of the human hair follicle. Acne is closely related to immune cytokines and cells including T helper 17cells (Th17 cells). Mis-regulated glycolipid metabolism also plays a vital role in the process. Objective: This investigation aimed to explore the role of IL-17 in signaling pathways controlling sebaceous gland lipoprotein metabolism in a rat model of acne. Methods: We generated the rat ear acne model, and investigated the pathological changes of acne skin tissue by histological analysis and the changes in the critical factors including DEFB1, GPR65, FADS1, and FADS2 by Western Blot in this model. Results: There were more Th17 cells in the rat ear acne model than in the control mice. The expression levels of DEFB1, GPR65, FADS1, FADS2 and MOGAT1 were significantly upregulated in serum and tissue from rat acne model, which could be concluded that the Th17 cells play a major role in the pathogenesis of acne based. Conclusion: Although acne is associated with immune effects and glycolipid metabolism, inhibition of IL-17 signaling pathway might be a novel way for acne therapy. Our findings also suggest a new strategy for targeted therapy of acne.  相似文献

目的 探讨抗幽门螺杆菌(Hp)治疗对Hp阳性寻常型银屑病患者疗效的影响及Hp感染与寻常型银 屑病发病的可能机制。方法 选取2019年12月-2021年9月重庆三峡医药高等专科学校附属医院皮肤科确诊 的50例Hp阳性寻常型银屑病患者,采用随机数字表法分成试验组与对照组,每组25例。试验组予以外用卤 米松乳膏、卡泊三醇软膏联合四联抗Hp治疗,对照组予以外用卤米松乳膏、卡泊三醇软膏治疗,比较两组 治疗前、治疗后1个月PASI评分以及血清IL-17水平。结果 两组治疗后PASI评分低于治疗前,且试验组低 于对照组,差异有统计学意义(P<0.05);两组治疗后IL-17水平低于治疗前,且试验组低于对照组,差 异有统计学意义(P<0.05)。结论 对Hp阳性寻常型银屑病患者进行抗Hp治疗有利于提高患者临床疗效, Hp感染可能通过诱导血清IL-17水平升高而参与银屑病的发生与发展。  相似文献

Thymus vulgaris, Thymus satureioides, and Thymus zygis are endemic Moroccan species that are intensively used due to their extensive medications and culinary properties. To enhance and preserve these overexploited species, the effect of provenance on the chemical composition of essential oils and antimicrobial activity against human pathogens were studied. Essential oils (EO) obtained by hydrodistillation from the flowering tops of thyme species were analyzed by GC-SM. The determination of minimum inhibitory (MIC), bactericidal (MBC), and fungicide (MFC) concentrations of EO were studied by microplate microdilution. The correlation between the chemical composition of EO and antimicrobial properties were evaluated using R software. The samples studied gave variable yields, ranging from 0.70 ± 0.03% to 4.12 ± 0.21%. The main constituents of Thymus vulgaris harvested from the municipality of El Hammam are carvacrol (68.8%), γ-terpinene (11.5%), and p-cymene (3.9%), while borneol (41.3% and 31.7%) and carvacrol (14.6% and 9.8%) are the most abundant in Thymus satureioides of the communes of Tata and Tigrigra respectively. For Thymus zygis, the results revealed the dominance of carvacrol (51.7% and 57.5%) for the municipalities of Tigrigra and Ain Aghbal, thymol (47.1% and 42.1%) for the municipalities of Bensmim and Timahdite respectively. These chemical profiles have similarities, but also reveal differences from the results given in the literature. In addition, the essential oils most active towards the microorganisms evaluated were those of Thymus vulgaris, followed by Thymus zygis and Thymus satureioides. These EO have very powerful MIC (MIC ? 300 μg/ml) against Gram-negative bacteria, and in particular, concerning Enterobacters cloacae, Citrobacter koseri, and Acinetobacter baumannii. Thymus zygis EO is the most active on candidates compared to Thymus vulgaris and Thymus satureioides EO, except Candida dubliniensis which was inhibited by Thymus satureioides EO from the commune of Azrou with a MIC = 18.75 μg/ml. The correlation determined between the major components and MIC showed that phenols have the strongest positive effects on antimicrobial properties, followed by terpenes and non-aromatic alcohols. In addition, different sensitivities of pathogens to chemical families have been observed against Enterobacter cloacae, Citrobacter koseri, Candida parapsilosis, Staphylococcus aureus multiresistant, Pseudomonas aeruginosa, Acinetobacter baumannii, and Aspergillus niger. Our results support the idea that these oils could be very useful in flavoring, food preservation, as well as a source of antimicrobial agents of great power against multidrug-resistant strains.  相似文献

Introduction

Body dysmorphic disorder (BDD) is a mental health condition that is difficult to diagnose; it can cause a great deal of suffering, and treatment is often complex and challenging.

Material and method

The study population comprised 81 consecutive dermatology out-patients who met the inclusion criteria for participation. Participants were treated at hospitals in both urban (Zaragoza) and rural areas (Alcañiz). The project was based on a prospective and observational pilot study. Assessment instruments used: Cook's Acne Grading Scale and Body Dysmorphic Disorder Questionnaire (BDDQ) (Spanish translation).Possible cases of BDD were identified by means of 2 criteria: 1) A positive result in the BDDQ (4 positive points and a negative exclusion question); and, 2) A Cook's Acne Grading Score that reflected non-noticeable/mild lesions (the most stringent criteria) or moderate lesions (least stringent criteria)

Results

The age range of the patients was from 13 to 43 years old. The average age was 19 with a standard deviation of 6.2. Of the 81 participants, 54.3% were women. 61.7% were seen in a rural hospital (Alcañiz Hospital) and 38.3% in an urban one (University Hospital of Zaragoza). When more restrictive criteria regarding the seriousness of the condition were applied (only patients with mild acne), the BDDQ screening resulted in a positive BDD prevalence rate of 8.6% (7 patients); if the criteria were less restrictive (including patients with moderate lesions), the rate was 14.8% (12 patients).

Discusion

Patients who screened positive for BDD reported spending an average of 2 hours a day thinking and worrying about their appearance. These results highlight the importance of screening for possible cases of BDD in order to follow up these patients and recommend they be seen by a mental health specialist to confirm the diagnose and offer treatment for the disorder. BDD has a serious and negative impact on the lives of those affected.  相似文献

目的 确定当前饶河地区宿主动物所携带病原体的基因型别,分析其变异情况,对该地区自然宿主动物的感染情况进行监测。方法 使用TRIZOL法提取待测样本RNA,经RT-PCR扩增后对PCR产物进行核苷酸序列测定。应用DNAStar软件包对核苷酸序列进行同源性比较,构建系统进化树和氨基酸序列的比对。结果 在饶河地区,除褐家鼠(Rattus norvegicus)以外,松鼠(Sciurus vulgaris)也携带SEOV。本次从3只褐家鼠和1只松鼠体内分离出汉城型汉坦病毒(Seoul virus, SEOV),4株SEOV的遗传距离范围为0.00~0.01,与黑龙江地区常见SEOV病毒株亲缘关系较近。结论 黑龙江地区的气候和自然地理条件非常适合携带汉坦病毒(HV)宿主动物的生存和繁殖,但是随着人们生活条件的改善,禁止伐木狩猎,家鼠和野鼠与人类交集的逐渐减小,肾综合征出血热(HFRS)在黑龙江省暴发的概率也越来越小。  相似文献
