Minocycline-induced pigmentation is a rare dermatological condition that primarily affects the skin and thyroid gland, oral mucosa, nails, teeth, bones, and sclera leading to grayish-blue pigmentation in these areas. Early identification, discontinuation of the drug, and laser treatment are crucial in managing this condition. We reported a case involving a 72-year-old Chinese woman who developed diffuse blue-brown pigmentation after 1 year of minocycline treatment for pemphigus vulgaris.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a disease that causes an abnormal accumulation of fat in the liver, triggering inflammation and fibrosis, the mechanism of which is not fully understood and for which there is a lack of specific drug therapy. Far-infrared radiation (FIR) has demonstrated evident therapeutic efficacy across various diseases, and novel nanomaterial graphene patches can emit it through electric heating. This study aimed to investigate the potential protective effects of FIR against MAFLD.

Background: Androgenetic alopecia (AGA) is the most common type of androgen-associated hair loss. Previous studies have indicated an association between the gut microbiota and AGA. To delve deeper, we executed a two-sample Mendelian randomization (MR) analysis to investigate the potential causal relationship between the gut microbiota and AGA.

Background: Acquired perforating dermatosis (APD) is a rare skin condition characterized by degenerated materials eliminated from the dermis. Several retrospective studies on APD have been reported; however, few data are available on Chinese APD and their features on dermoscopy and reflective confocal microscope (RCM) assays.

Objective: The aim of this study was to retrospectively evaluate the clinical and histopathologic data of 37 acquired perforating dermatosis cases, and assess their features on dermoscopy and RCM.

Erdheim-Chester disease (ECD) is a rare histiocytic disorder that can present as a localized infiltration of foamy histiocytes or a multisystem disease that may be life-threatening. It is extremely rare in children. Pegoraro and colleagues present the clinical and molecular features of 21 patients with pediatric ECD through a large international collaboration, documenting that it resembles its adult counterpart, with similar molecular features and responses to agents targeting BRAF and MEK.

The main pathogenic factor in atopic dermatitis (AD) is Th2 inflammation, and levels of serum CCL17 and CCL22 are related to severity in AD patients. Fulvic acid (FA) is a kind of natural humic acid with anti-inflammatory, antibacterial, and immunomodulatory effects. Our experiments demonstrated the therapeutic effect of FA on AD mice and revealed some potential mechanisms.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disorder. Bristol Stool Form Scale (BSFS) is a widely used stool scoring method that could indirectly reflect intestinal function.

Objectives: To evaluate the associations of AD with BSFS.

Wulongzhiyangwan (WLZYW) is a Chinese prescription medicine for the treatment of pruritus, but its mechanism has not been clarified. The purpose of this study was to explore the mechanism of WLZYW in pruritus through network pharmacology analysis and experimental validation. The active components and corresponding targets of WLZYW were obtained from the Traditional Chinese Medicine Systematic Pharmacology (TCMSP) database.

The impact of artificial light at night (ALAN) exposure on health has become increasingly prominent. However, little is known about the effect of ALAN exposure on atopic diseases. In this study, a cross-sectional analysis of incoming students was conducted in 5 geographically disperse universities which locate in Changsha (south), Wuhan (central), Xiamen (east), Urumchi (west), and Hohhot (north), respectively.

Background: Overuse and misuse of antibiotics is a public health problem in low-income and middle-income countries. Although the association of antibiotics with atopic and allergic diseases has been established, most studies focused on prenatal exposure and the occurrence of disease in infants or young children.

Objective: To investigate the association of preschool use of antibiotics with atopic and allergic skin diseases in young adulthood.

Rationale: Coronary artery ligation to induce myocardial infarction (MI) and ischemia injury in mice is typically performed in normal mice, but This is not consistent with disease progression. There should be atherosclerosis (AS) first, followed by MI.

Objective: We tried a novel model to induce MI that was established on atherosclerosis in mice.

Acquired perforating dermatoses (APDs) are a group of diverse skin disorders in patients with systemic disease, most commonly chronic renal failure and diabetes mellitus. APD induced by medication has seldom been reported. Anti-PD-1 monoclonal antibody has recently been used as a broad-spectrum, effective, durable, and relatively safe antitumor therapy for various malignancies.

It is understudied how frequently adolescents use nutritional supplements (NS) and whether the corresponding behavior is associated with skin diseases that may cause unpleasant symptoms and disfigurement. The current study aimed to investigate the prevalence of NS use in Chinese college students and its association with inflammatory skin diseases. This was a university-based epidemiologic investigation that included 20,138 students who underwent dermatological examinations.

Objective: Glycogen phosphorylase B (PYGB), the rate-determining enzyme in glycogen degradation, plays a critical role in progression of various tumors. The present study focused on the potential molecular mechanism toward PYGB in non-small cell lung cancer (NSCLC) progression.

Methods: Expression of PYGB in NSCLC tissues and cell lines was evaluated via quantitative real-time PCR (qRT-PCR), western blot and immunohistochemistry.

Smoking has been identified as a risk factor for atopic dermatitis and hand eczema, but less is known about the association of exposure to second-hand smoke (SHS) with hand eczema. The study aimed to investigate the association of SHS exposure with hand eczema and atopic dermatitis in a group of adolescents. We conducted a cross-sectional study among first-year college students.

Background: Infection with plasmid-free Chlamydia trachomatis and Chlamydia muridarum fails to induce severe pathology, however, the mechanisms underlying this phenotype are unclear.

Objectives: To elucidate the mechanisms of chlamydial plasmid-mediated pathology in mouse oviducts.

Materials & Methods: BALB/c mice were intravaginally infected with either plasmid-competent or plasmid-free C.

BACKGROUND The anti-microbial protein cathelicidin LL-37 plays an important role in the pathogenesis of psoriasis by inducing inflammation. Our previous study showed that the chlamydial plasmid-encoded protein pGP3 forms a stable complex with LL-37 to neutralize its pro-inflammatory activity. Here, we explored whether pGP3 can inhibit the development of lesions in mice with imiquimod-induced psoriasis.
