Ob.ective: Xeroderma pig.entosum (XP) is a rare autosomal recessive dermatosis caused b. g.netic defects of DNA repair. This study was performed to detect and analyz. the g.nes of 2 Uyg.r patients with XP and their families and assess the patients' phenotypes, which may enrich the understanding.of the g.netic skin disorder spectrum in Xinjiang.area. Methods: We collected the clinical data from 2 patients with XP and peripheral b.ood samples from the patients and their family memb.rs. The patients' DNA was sequenced and detected b. Sang.r sequencing. and g.ne mutations were screened. Results: The prob.nd in family 1 presented with b.own maculae at the exposure site and squamous cell carcinoma secondary to a facial rash. The prob.nd had a homoz.g.us nucleotide variation of XPC c.2251-2A> g.(A chang. from A to g.in the penultimate position of the intron b.fore the 2251 position in the coding.reg.on), which was a shear mutation. In this family, b.th parents were heteroz.g.us, and no similar mutation detected in the sister. In family 2, the prob.nd had scattered b.ack b.own spots and papules on the trunk and limb.. and his young.r sister was also a patient. The prob.nd and his young.r sister had homonucleotide variation of XPA c.631C> T, which was nonsense mutation, resulting.in the codon for Arg.No.211 b.ing.chang.d into termination codon (***211X), thus terminating.the peptide chain synthesis prematurely. All the normal individuals in the two families were heteroz.g.tes, and homoz.g.us mutations occurred in all the patients, which was consistent with the autosomal recessive inheritance. Conclusion: XP is rare in Uyg.r population. This study expanded the mutation spectrum of XP and provided a b.sis for early diag.osis, treatment, prog.ostic prediction, and prenatal g.netic consultation. © 2022 Hospital for Skin Diseases (Institute of Dermatolog.), Chinese Academy of Medical Sciences, and Chinese Medical Association, pub.ished b.

Ob.ective: Ultrasonog.aphy is a diag.ostic imag.ng.technique used to visualiz. sub.utaneous b.dy structures for identification of possib.e patholog.es. In this study, we aimed to explore the clinical sig.ificance of hig.-frequency ultrasound in differentiating.the location of b.isters b.tween pemphig.s and b.llous pemphig.id. Methods: Eig.teen patients were recruited in Department of Dermatolog., z.ong.a Hospital from 2020 to 2021 and divided into a pemphig.s g.oup (n = 8) and a b.llous pemphig.id g.oup (n = 10) according.to the diag.ostic criteria for each. Ultrasonog.aphic imag.s were collected using.a 50-MHz.hig.-frequency ultrasound system. The indexes of ultrasonic evaluation were the layer (epidermis or dermis), siz., shape, internal echo, and b.undary of the b.ister. Categ.rical variab.es are expressed as n (%), and differences were compared using.Fisher's exact test. Results: The ultrasonog.aphic imag.s in the pemphig.s g.oup showed an intraepidermal semi-arc or irreg.lar anechoic or hypoechoic areas. The inferior b.rders were situated ab.ve the characteristic thin linear hyperechoic b.nds of the epidermis. A linear hypoechoic b.nd was present at the dermoepidermal junction in some cases. In the ultrasonog.aphic imag.s of the b.llous pemphig.id g.oup, the linear hyperechoic b.nds of the epidermis were continuous and intact. An oval fluid anechoic area (sub.pidermal b.ister) was present immediately b.low the b.nds. The location of the b.isters in the ultrasonog.aphic imag.s was sig.ificantly different b.tween the 2 g.oups (P g.-frequency ultrasound can b. used as an auxiliary means to differentiate the location of b.isters b.tween pemphig.s and b.llous pemphig.id. © 2022 Hospital for Skin Diseases (Institute of Dermatolog.), Chinese Academy of Medical Sciences, and Chinese Medical Association, pub.ished b.

Ob.ective: Psoriasis is associated with a hig. prevalence of metab.lic syndrome (MS), and patients with concomitant psoriasis and MS are more severely affected and less responsive to treatment. However, the molecular mechanisms b.hind these effects are unknown. Recent studies have shown that leptin may serve as a molecular link b.tween psoriasis and MS, sug.esting.that hig. leptin concentrations may exacerb.te psoriasis. However, the molecular mechanism of this effect is still unclear. We aimed to investig.te the effect of leptin on autophag. in patients with psoriasis. Methods: From January 2021 to June 2022 in PLA g.neral Hospital, we enrolled 51 patients with psoriasis, including.21 patients with MS and 30 without MS, and 30 healthy controls who had underg.ne nevus surg.ry. We measured the epidermal leptin, P62, and LC3b.concentrations of patients b. immunohistochemistry, and measured the serum leptin concentration b. enz.me-linked immunosorb.nt assay. We then performed correlation analyses to compare these proteins' concentrations b.tween patients with concomitant psoriasis and MS, patients with psoriasis alone, and healthy control g.oups. Additionally, we performed western b.otting.after in vitro culture of HaCaT cells with different concentrations of leptin and measured the expression levels of the autophag. markers b.clin1, LC3b. and P62; the differentiation markers K10, K16, and K17; and PI3K/AKT/mTOR sig.aling.pathway-related proteins of HaCat cells. Next, we transfected ATg. into HaCaT cells to revert autophag. and used the specific PI3K inhib.tor Ly294002 to b.ock PI3K/AKT/mTOR sig.aling. The expression levels of K10, K16, and K17 of HaCat cells were ag.in measured. One-way analysis of variance was used for the comparison of means of multiple samples, and LSD-t post hoc test was used for comparison b.tween the 2 g.oups.
