Objective To detect the mutations in ATP2C1 gene in 3 Chinese Hailey-Hailey-disease (HHD) families and 1 sporadic HHD patient.Methods Three Chinese HHD families and 1 sporadic HHD patient were recruited into this study with informed consent.Blood samples were taken from the patients with HHD,unaffected individuals in the HHD families and 100 unrelated normal human controls.Genomic DNA was extracted from these blood samples.All the exons and exon-intron boundaries of the ATP2C1 gene were amplified by PCR followed by direct sequencing via dye-termination chemistry.Results Three novel missense mutations in ATP2C1 gene were identified,including a 2048 G→A mutation in exon 20 causing the substitution of arginine by lysine at position 619 in the patients from HHD family 1,853A→C mutation in exon 8 causing the substitution of threonine by proline at position 221 in the patients from family 2,and 2323T→C mutation in exon 23 causing the substitution of tyrosine by histidine at position 711.None of these mutations were found in patients from the HHD family 3,unaffected individuals from the HHD family 1 and 2,or the unrelated normal human controls.Conclusion Three novel missense mutations are identified in the ATP2C 1 gene of patients with HHD.

Objective To evaluate the value of MR in the diagnosis of primary splenic lymphoma (PSL).Methods The MR imaging features of 3 PSL cases proved by pathology were retrospectively reviewed. Results Three cases were all pathologically diagnosed as B-cell non-Hodgkin's lymphoma(NHL). Two cases were multiple node shape and one was massive shape. Unenhanced MR imaging revealed heterogeneous splenic enlargement, with large nodules showing iso-hyperinternse on T1WI and hypointense on T2WI. Linear hyperintense on T1WI and T2WI was seen on the spleen peripherous. The spleen vascular was infiltrated. CE-MRI showed heterogeneous enhancement of spleen with iso-hypointense. The focus of postperitoneal showed medial enhancement. Immunohistochemistry-showed 2 cases of diffuse B cell. The CD20 and CD19 α of tumor cell showed diffuse( + ) ,CD3 ,CD5 individual( + ) ,CD43 ( + ) ,CD45RO( + ), CD10 ( +/- ), Mum ( + ), MAC387 individual ( + ), 1 case of B lymphocell type, CD79α ( + ) ,CD23( + ) ,CD38( + ) ,λ( + ). Conclusion The MR imaging features of PSL were characteristic and helpful in the diagnosis of PSL, but the correct diagnosis was still dependent on the pathology and immunohistochemical staining.

Skin microbiota is associated with various skin diseases. Scalp hair follicles penetrate deeply into the skin, and carry complex microbial communities distinct from those on the skin surface. Local imbalance of microbial communities may impair the skin barrier function, leading to a variety of hair and scalp diseases. This review discusses changes in microbial diversity and colonization by specific microorganisms in various hair diseases, including dandruff, folliculitis decalvans, etc., and provides new ideas for exploring the pathogenesis of and therapeutic strategies for various hair and scalp diseases.

Objective To compare the efficacy of mediastinoscope-assisted transhiatal esophagectomy (MATHE) and functional minimally invasive esophagectomy (FMIE) for esophageal cancer. Methods Patients who underwent minimally invasive esophagectomy at Jining No.1 Hospital from March 2018 to September 2022 were retrospectively included. The patients were divided into a MATHE group and a FMIE group according to the procedures. The patients were matched via propensity score matching (PSM) with a ratio of 1 : 1 and a caliper value of 0.2. The clinical data of the patients were compared after the matching. Results A total of 73 patients were include in the study, including 54 males and 19 females, with an average age of (65.12±7.87) years. There were 37 patients in the MATHE group and 36 patients in the FMIE group. Thirty pairs were successfully matched. Compared with the FMIE group, MATHE group had shorter operation time (P=0.022), lower postoperative 24 h pain score (P=0.031), and less drainage on postoperative 1-3 days (P<0.001). FMIE group had more lymph node dissection (P<0.001), lower incidence of postoperative hoarseness (P=0.038), lower white blood cell and neutrophil counts on postoperative 1 day (P<0.001). There was no statistically significant difference in the bleeding volume, R0 resection, hospital mortality, postoperative hospital stay, anastomotic leak, chylothorax, or pulmonary infection between the two groups (P>0.05). Conclusion Compared with the FMIE, MATHE has shorter operation time, less postoperative pain and drainage, but removes less lymph nodes, which is deficient in oncology. For some special patients such as those with early cancer or extensive pleural adhesions, MATHE may be a suitable surgical method.
