Objective:To explore the clinical outcome and applicability of the comb flap technique and stepwise design concept in plastic aesthetic and reconstructive surgery.Methods:The clinical data of patients who underwent plastic aesthetic and reconstructive surgery with the comb flap technique in Shanghai Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2022 were retrospectively analyzed. The application of the comb flap technique follows the concept of stepwise design, that was, preoperative and intraoperative design and adjustment were carried out step by step and in sequence, and the design was combined with the surgical procedure. Its main operations included: an incision was designed along the edge of the target area, the tissue flap was widely separated at the base of the target area. The tissue flap was cut in sequence perpendicular to the cutting edge and temporarily sutured and fixed, the edge was cut and fixed. During the operation, the tension of the incision and the local appearance could be adjusted. The incisal edge was finely sutured, and the temporary suture was finally removed. The healing of surgical incision and complications were observed after the operation, and the facial recovery and surgical effect were followed up.Results:Six patients were enrolled, including 3 males and 3 females, aged from 2 to 58 years. One patient underwent upper eyelid tightening and lower eyelid blepharoplasty through subeyebrow incision. One patient underwent middle and lower face rhytidectomy. One patient underwent thick lip thinning and right facial liposuction. One patient underwent facial congenital melanocytic nevi resection. One patient underwent eyebrow congenital melanocytic nevus resection. One patient underwent facial flap repair. All patients had primary healing of incision, and no surgery-related complications occurred. All patients were followed up for 3 to 18 months, and all patients were satisfied with the surgical effect.Conclusion:The application of comb flap technique and stepwise design concept in plastic aesthetic and reconstructive surgery can delicately adjust the alignment of the incision margin, make the tension evenly distributed, and reduce the risk of scar formation and deformity after the operation. It has a wide range of clinical applications and good applicability.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with unclear etiology and limited treatment options. The median survival time for IPF patients is approximately 2-3 years and there is no effective intervention to treat IPF other than lung transplantation. As important components of lung tissue, endothelial cells (ECs) are associated with pulmonary diseases. However, the role of endothelial dysfunction in pulmonary fibrosis (PF) is incompletely understood. Sphingosine-1-phosphate receptor 1 (S1PR1) is a G protein-coupled receptor highly expressed in lung ECs. Its expression is markedly reduced in patients with IPF. Herein, we generated an endothelial-conditional S1pr1 knockout mouse model which exhibited inflammation and fibrosis with or without bleomycin (BLM) challenge. Selective activation of S1PR1 with an S1PR1 agonist, IMMH002, exerted a potent therapeutic effect in mice with bleomycin-induced fibrosis by protecting the integrity of the endothelial barrier. These results suggest that S1PR1 might be a promising drug target for IPF therapy.

The aim of this study was to evaluate the roles of interleukin (IL)-17A in risk stratification and prognosis of patients with sepsis-associated acute kidney injury (SAKI). Methods: We enrolled 146 sepsis patients (84 non-SAKI and 62 SAKI patients) admitted to the emergency department from November 2020 to November 2021. Patients with SAKI were differentiated based on the severity of acute kidney injury. All clinical parameters were evaluated upon admission before administering antibiotic treatment. Inflammatory cytokines were assessed using flow cytometry and the Pylon 3D automated immunoassay system (ET Healthcare). In addition, a receiver operating characteristic (ROC) curve was utilized to determine the prognostic values of IL-17A in SAKI. Results: The levels of creatinine, IL-2, IL-4, IL-6, IL-17A, tumor necrosis factor alpha, C-reactive protein, and procalcitonin (PCT) were significantly higher in the SAKI group than in the non-SAKI group (p < 0.05). The level of IL-17A revealed significant differences among stages 1, 2, and 3 in SAKI patients (p < 0.05). The mean levels of PCT, IL-4, and IL-17A were significantly higher in the non-survival group than in the survival group in SAKI patients (p < 0.05). In addition, the area under the ROC curve of IL-17A was 0.811. Moreover, the IL-17A cutoff for differentiating survivors from non-survivors was 4.7 pg/mL, of which the sensitivity and specificity were 77.4% and 71.0%, respectively. Conclusion: Elevated levels of IL-17A could predict that SAKI patients are significantly prone to worsening kidney injury with higher mortality. The usefulness of IL-17A in treating SAKI requires further research.

This article reports a pedigree with two previously deceased neonates. Both neonates did not experience asphyxia but passed away on their 5th and 13th day of life. The chromosomal analysis of the parents' karyotype revealed no abnormalities. Clinical manifestations of the two deceased cases and relevant medical records were recollected. Whole exome sequencing was conducted on the stem blood sample of Neonate 2, revealing a c.729_730insTT homozygous mutation (p.D244Lfs*39) in the methylmalonyl-CoA mutase gene (NM_000255). It was confirmed that Neonate 2 was affected with methylmalonic acidemia. Amniocentesis was performed at 20 +3 weeks in the current pregnancy. Sanger sequencing of amniotic fluid indicated that the fetus carried the same gene mutation as Neonate 2. Consequently, the fetus was expected to be a patient with methylmalonic acidemia and to exhibit the same phenotype as Neonate 2. Termination of pregnancy, therefore, was selected at 24 weeks of gestation.

Autophagy is a critical cellular homeostatic mechanism, and its dysfunction is linked to invasive breast carcinoma (BRCA). Recently, several omics methods have been applied to explore autophagic regulators in BRCA; however, more reliable and robust approaches for identifying crucial regulators and druggable targets remain to be discovered. Thus, we report here the results of multi-omics approaches to identify potential autophagic regulators in BRCA, including gene expression (EXP), DNA methylation (MET) and copy number alterations (CNAs) from The Cancer Genome Atlas (TCGA). Newly identified candidate genes, such as

Objective:This study proposed a new clinical classification and treatment strategies for periocular arteriovenous malformation (AVM).Methods:A retrospective analysis of the cases of periocular AVM from Jan 2015 to Jan 2019 was included in this study. According to the DSA angiography results, which type of the ophthalmic artery connected with the AVMs, three types of classification were initiated: type 1 is unilateral ophthalmic artery blood supply the lesion and the central retinal artery is not involved; type 2 is bilateral ophthalmic artery blood supply and the central retinal artery is not involved; type 3 is unilateral or bilateral ophthalmic artery blood supply and the central retinal artery is involved. Type 3 can be subdivided into 3a and 3b subtypes according to the visual acuity of the affected eye. Type 3a is the presence of vision; type 3b is the loss of vision. Type 1 patients were treated with super-selective onyx embolisation of the feeding arteries of AVMs through the ocular arteries and then treated with ethanol embolotherapy; Type 2 patients were treated with bilateral super-selection onyx embolisation of the feeding arteries of AVMs through the ocular arteries and then were treated with ethanol embolotherapy; type 3a patients were treated with ethanol embolotherapy combined with surgery; type 3b patients were treated with enucleation and orbital reconstruction.Results:There were 32 cases in this study. For 6 cases of type 1, The treatment course was 1-5 sessions, with an average of 2.1 sessions. 5 cases were cured, 1 case was improved, 1 case occured minor complication (superficial tissue necrosis), which was self-healing; In 8 cases of type 2, 4 cases were treated with interventional therapy for 1-7 sessions, with an average of 2.5 sessions. 3 cases were cured, 5 cases were improved, 1 case had minor complication (superficial tissue necrosis). Among the 4 cases treated by operation, 3 cases were repaired by expanded flap, 1 case by local flap. 1 case was cured, and 3 cases was improved, without operation related complications; In 13 cases of type 3a, 3 cases was cured, 10 cases was improved, 2 cases had intervention therapy related minor complications (superficial tissue necrosis) which was self-healed, 1 case had operation related complications (small area necrosis of flap, necrosis area was treated by dressing). In 5 cases of 3b type, 2 cases were cured, 3 cases were improved, and 1 case had operation related complication (partial necrosis of flap, thedefect was further repaired by skin grafting).Conclusions:The classification of periocular arteriovenous malformations has its significance for guiding the selection of treatment strategies. Combining ethanol embolotherapy, neurological intervention techniques, and plastic and reconstructive techniques are essential to achieve better clinical outcome in the treatment of periocular AVM with minimal complications.
