简介：颈椎病是骨伤临床上的常见疾病，也是世界性的一大类疑难病。严重危害着患者的正常生活和工作效率。目前在全世界范围内对该病的治疗方法大致可分为三类疗法。一是手术疗法，但因其疗效和风险俱存而会使许多患者“望而生畏”；二是药物疗法，但只有一部分轻度患者能得以康复；三是针灸按摩和理疗方法，虽然可取得部分疗效，但因为掌握该方法的医师在辨证施治中存在着参差不齐的水平问题，也很难达到令患者满意的效果。

简介：AbstractIntroduction:Trichofolliculoma characterized clinically by the presence of acentral dilated pore with tufted hairs and corresponds histologically to a central primary follicle and many secondary vellus hair follicles originating from it. Thus far, dermoscopy description of trichofolliculoma has been lacking.Here, we describe a typical case of trichofolliculoma, particularly the special manifestation under the dermoscopy.Case presentation:A 29-year-old man complained a five-year history of a nodule containing a central whitish hair plug on his left tempus. Dermoscopic examination revealed a well-defined, yellow macule with a central whitish hair plug surrounded by dilated capillaries, and histopathological analysis was consistent with trichofolliculoma.Discussion:The findings of dermoscopy were also vary, which may be affected by the origin of the disease, various phases of the hair cycle, depth of the lesion, and even external stimulus.Conclusion:Diagnosis of trichofolliculoma is sometimes difficult because the presence of the central crater and visible hairs is low, and dermoscopy examination may be a potentially useful diagnostic tool.

简介：AbstractBackground:Anorexia nervosa (AN) is a psychological disorder, which is characterized by the misunderstanding of body image, food restriction, and low body weight. An increasing number of studies have reported that the pathophysiological mechanism of AN might be associated with the dysbiosis of gut microbiota. The purpose of our study was to explore the features of gut microbiota in patients with AN, hoping to provide valuable information on its pathogenesis and treatment.Methods:In this cross-sectional study, from August 2020 to June 2021, patients with AN who were admitted into Peking University Third Hospital and Peking University Sixth Hospital (n = 30) were recruited as the AN group, and healthy controls (HC) were recruited from a middle school and a university in Beijing (n = 30). Demographic data, Hamilton Depression Scale (HAMD) scores of the two groups, and length of stay of the AN group were recorded. Microbial diversity analysis of gut microbiota in stool samples from the two groups was analyzed by 16S ribosomal RNA (rRNA) gene sequencing.Results:The weight (AN vs. HC, [39.31 ± 7.90] kg vs. [56.47 ± 8.88] kg, P < 0.001) and body mass index (BMI, AN vs. HC, [14.92 ± 2.54] kg/m2vs. [20.89 ± 2.14] kg/m2, P < 0.001) of patients with AN were statistically significantly lower than those of HC, and HAMD scores in AN group were statistically significantly higher than those of HC. For alpha diversity, there were no statistically significant differences between the two groups; for beta diversity, the two groups differed obviously regarding community composition. Compared to HC, the proportion of Lachnospiraceae in patients with AN was statistically significantly higher (AN vs. HC, 40.50% vs. 31.21%, Z = –1.981, P = 0.048), while that of Ruminococcaceae was lower (AN vs. HC, 12.17% vs. 19.15%, Z = –2.728, P = 0.007); the proportion of Faecalibacterium (AN vs. HC, 3.97% vs. 9.40%, Z = –3.638, P < 0.001) and Subdoligranulum (AN vs. HC, 4.60% vs. 7.02%, Z = –2.369, P = 0.018) were statistically significantly lower, while that of Eubacterium_hallii_group was significantly higher (AN vs. HC, 7.63% vs. 3.43%, Z = –2.115, P = 0.035). Linear discriminant effect (LEfSe) analysis (LDA score >3.5) showed that o_Lachnospirales, f_Lachnospiraceae, and g_Eubacterium_hallii_group (o, f and g represents order, family and genus respectively) were enriched in patients with AN. Microbial function of nutrient transport and metabolism in AN group were more abundant (P > 0.05). In AN group, weight and BMI were significantly negatively correlated with the abundance of Bacteroidota and Bacteroides, while positively correlated with Subdoligranulum. BMI was significantly positively correlated with Firmicutes; HAMD scores were significantly negatively correlated with Faecalibacterium.Conclusions:The composition of gut microbiota in patients with AN was different from that of healthy people. Clinical indicators have correlations with the abundance of gut microbiota in patients with AN.
