In the acute phase of sepsis, patients tend to experience a hyperinflammatory state; however, in addition to facilitating the elimination of invading pathogens, this severe hyperinflammatory response can also lead to damage to the host. Thus, to maintain immune system homeostasis, counterregulatory immune responses, referred to as compensatory anti-inflammatory responses (CARs), are initiated. However, in the context of sepsis, the stabilization of the immune system cannot be sustained and protracted CARs can lead to an immunosuppressive state, which makes septic patients highly susceptible to secondary infection and high mortality. Various studies have indicated that the expression of NOD-like receptor (NLR) with a caspase activation and recruitment domain 3 (NLRC3), a member of the NLR family, tends to decrease several hours to days after the onset of infection but afterward increases over time and can mediate the dysfunction of immune effector cells in numerous ways, playing a crucial role in the development of septic immunosuppression.

Reconstruction must restore both aesthetic and function, particularly given the substantial dimensional changes of penile skin during erection.

The present study reported a case of massive left testicular, scrotal and penile skin avulsion, successfully managed using a split-thickness skin graft in combination with a novel multi-anchor fixation technique, resulting in optimal functional and cosmetic outcomes. A 39-year-old man sustained a severe perineal crush-avulsion injury after accidental entanglement in a conveyor belt. The injury resulted in complete avulsion of the penile skin, extensive scrotal skin loss, complete avulsion of the left testis and epididymis and exposure of the right testis, accompanied by active bleeding. The avulsed tissues were markedly fragmented and contaminated with machine oil. After thorough debridement of non-viable tissue, reconstruction was performed using a split-thickness skin graft harvested from the right anterolateral thigh. A novel multi-anchor fixation technique was used to secure the graft to key anatomical points on the tunica albuginea, thereby preventing graft redundancy, displacement and adhesion while preserving physiological compliance during erection. Follow-up at 6-12 months demonstrated complete wound healing, preserved penile morphology, normal erectile function and satisfactory sexual performance. In conclusion, split-thickness skin grafting combined with multi-anchor fixation can provide reliable coverage and restore penile morphology and function after severe penoscrotal degloving injury.

Therefore, an ovalbumin (OVA)-induced AR mouse model was established to investigate whether quercetin can treat AR by regulating the TLR4/MyD88/IRAK4 signaling pathway. OVA and aluminum hydroxide were injected intraperitoneally for sensitization, and OVA was dripped into the nose to establish a mouse model of AR. The mice were scored on behaviors such as scratching, sneezing and a runny nose to assess the success of the modeling. The treatment groups were given the relevant drugs (dexamethasone and quercetin) by gavage for 1 week after successful modeling. Following the completion of treatment, the serum OVA-IgE, IL-4, IL-13, IL-1β, IL-17 and IL-10 levels were measured; changes in the nasal mucosa were observed; protein and mRNA expression levels of TLR4, MyD88, IRAK4 and NF-κB in lung tissue were determined; and changes in the percentages of regulatory T cells (Tregs) and T helper 17 (Th17) cells in the spleen were assessed. The results showed that compared with the normal control (NC) group, the allergic symptom scores were >10 points, and the serum levels of OVA-IgE, IL-4, IL-13, IL-1β and IL-17 increased, whereas the serum level of IL-10 decreased in the OVA group. Detachment and necrosis of the nasal mucosa, accompanied by tissue edema and inflammatory cell infiltration, were observed in the OVA group. Compared with the NC group, the relative expression mRNA and protein levels of TLR4, MyD88, IRAK4 and NF-κB in lung tissues increased, the percentage of Tregs decreased and the percentage of Th17 cells increased in splenocytes of the OVA group. Based on these results, it was hypothesized that quercetin inhibits inflammatory responses and induces immune tolerance by regulating the TLR4/MyD88/IRAK4 signaling pathway in a mouse model of AR.</p>","PeriodicalId":94002,"journal":{"name":"Experimental and therapeutic medicine","volume":"32 2","pages":"219"},"PeriodicalIF":2.3,"publicationDate":"2026-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13320216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148371547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
