BACKGROUND:During diabetic wound healing,the sustained activation of M1 macrophages exacerbates the inflammatory response and hinders wound repair.Auranofin,an anti-inflammatory drug,has not been clearly studied for its effects on M1 macrophages and its potential role in diabetic wound healing.OBJECTIVE:To investigate the effects of different concentrations of auranofin on the biological function of M1 macrophages and evaluate its potential application in diabetic wound healing.METHODS:RAW264.7 and THP-1 cells were used as research models.M1 polarization was induced using different concentrations of interferon-γ and lipopolysaccharide.M1 macrophages were treated with 1 and 2 μmol/L auranofin.Cell counting kit-8 assay was used to evaluate the effect of auranofin on cell viability.Quantitative real-time PCR was performed to detect mRNA expression of interleukin-1β,interleukin-6,and tumor necrosis factor-α.ELISA was employed to measure the levels of interleukin-1β,interleukin-6,and tumor necrosis factor-α in the supernatant.Western blot analysis was used to assess the expression of nuclear factor-κB(p65),phosphorylated mitogen-activated protein kinases(MAPK),and total MAPK proteins.Additionally,6-8-week-old male C57BL/6J and db/db diabetic mice were used for wound healing experiments,with the mice divided into C57 control,db/db control and auranofin treatment groups,each containing six animals.Dorsal skin defect modeling and treatment with intraperitoneal injection of auranofin were performed to observe wound healing in mice.RESULTS AND CONCLUSION:(1)Cell experiments showed that co-treatment with interferon-y(10 ng/mL)and lipopolysaccharide(100 ng/mL)significantly induced M1 polarization in RAW264.7 and THP-1 cells,resulting in increased mRNA expression of interleukin-1β,interleukin-6,and tumor necrosis factor-α.Treatment with auranofin(1 and 2 μmol/L)reduced the mRNA expression of these inflammatory factors in the cells and inhibited the secretion of inflammatory factors in the cell supernatant.(2)Auranofin treatment significantly suppressed the activation of nuclear factor-κB(p65)and phosphorylated MAPK signaling pathways.(3)Animal experiments showed that auranofin promoted wound healing in db/db diabetic mice,suggesting that auranofin has strong anti-inflammatory effects and may facilitate the healing of wounds in diabetic mice.

BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

OBJECTIVE: To investigate the effectiveness of free palmaris longus tendon graft reconstruction in the treatment of gouty tophus erosion lesions in flexor tendon of wrist and hand. METHODS: A retrospective analysis was conducted on 8 patients with gouty tophus erosion lesions in flexor tendon of wrist and hand who underwent free palmaris longus tendon graft reconstruction between June 2017 and December 2023. All patients were male, aged 22-65 years, with an average of 45.9 years. The duration of gout history ranged from 2 to 18 years, with an average of 8.8 years. The duration from the discovery of gouty tophus to operation ranged from 12 to 26 months, with an average of 17.6 months. The gouty tophus eroded the flexor pollicis longus tendon in 4 cases, with Verdan flexor tendon zones being Ⅰ-Ⅱ in 1 case and Ⅳ-Ⅴ in 3 cases. The flexor digitorum profundus tendons were affected in 2 cases for the index finger, 1 for the middle finger, and 1 for the ring finger, all located in zone Ⅳ-Ⅴ. The long axis of the gouty tophus ranged from 2.3 to 4.5 cm, with an average of 3.4 cm. All 8 patients presented with limited finger flexion and extension. Among them, 4 cases were accompanied by median nerve compression symptoms, and 1 case had associated bone and joint destruction in the hand. The total active motion (TAM) of the affected finger was (81.3±30.2)° before operation according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, and the functional evaluation was poor. The harvested palmaris longus tendon intraoperatively was 7-9 cm in length. RESULTS: Surgical incisions in all 8 patients healed by first intention, with no infections, graft non-union, or significant adhesion complications. All patients were followed up 8-25 months, with an average of 14.8 months. Numbness symptoms resolved in all 4 patients who presented with median nerve compression symptoms. Patients did not experience wrist pain or other discomfort, and function was not compromised. At last follow-up, according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, the TAM of 8 patients was (197.5±55.8)°, which significantly improved when compared with that before operation ( t=11.638, P<0.001); the hand function of 1 patient with gouty tophus in zone Ⅰ-Ⅱ flexor pollicis longus tendon was good, and the other 7 patients were excellent. CONCLUSION Free palmaris longus tendon graft reconstruction demonstrates good effectiveness in treating gouty tophus erosion lesions in flexor tendon of wrist and hand.

OBJECTIVE: To explore the effectiveness of multi-segment inverted Y-shaped vein transplantation using the anterior lateral malleolar venous network for repair of amputated palm injury distal to the superficial palmar arch. METHODS: Between September 2018 and July 2023, 5 patients with amputated palm injury distal to the superficial palmar arch were treated. There were 3 males and 2 females with an average age of 35.4 years (range, 29-52 years). The time from injury to admission was 1-6 hours (mean, 3.2 hours). The multi-segment inverted Y-shaped vein transplantation in the anterior lateral malleolar venous network were used to repair the common and proper palmar digital arteries; the another anterior lateral malleolar venous network was used to repair the dorsal vein of the hand. The soft tissue defect of dorsal hand in 1 patient was repaired with the pedicled ilioinguinal flap, and the wound at the donor site was directly sutured. Postoperative treatment included anti-infection therapy, antispasmodic therapy, and thrombosis prevention measures. RESULTS: The partial necrosis of the fingertip of the thumb occurred in 1 case, and the marginal necrosis of the abdominal flap after operation occurred in 1 case. The remaining fingers showed good blood supply with normal tension. The incision at donor site of the abdominal flap healed by first intention. All patients were followed up 8-41 months (median, 19 months). At last follow-up, the hand contour was satisfactory; the grasping function, opposition function, and proprioception recovered, and two-point discrimination ranged from 5 to 7 mm (mean, 6 mm). According to the upper extremity function evaluation criteria issued by Hand Surgery Society of the Chinese Medical Association, the functional outcomes were excellent in 3 cases, good in 1 case, and fair in 1 case. CONCLUSION The multi-segment inverted Y-shaped vein transplantation using the anterior lateral malleolar venous network for repairing defects in the common and proper palmar digital arteries distal to the superficial palmar arch offers advantages such as superficial location, flexible harvesting, and high compatibility. This technique has demonstrated favorable outcomes in complex transmetacarpal amputation reconstruction.

Objective To investigate the clinical effects of different right lung volume reduction techniques when the donor lung is oversized and mismatched with the recipient. Methods Clinical data of 10 recipients who underwent right lung volume reduction lung transplantation at the First Affiliated Hospital of Xi'an Jiaotong University from October 2022 to June 2024 were collected, including gender, age, primary disease type, and type of transplantation. A retrospective analysis was performed on postoperative complications within 90 days, duration of mechanical ventilation, hospital stay, and survival status to explore the impact of different volume reduction techniques on the survival rate of lung transplant recipients. Results A total of 10 right lung volume reduction recipients were included in this study, with 2 cases of upper lobe reduction, 7 cases of middle lobe reduction, and 1 case of lower lobe reduction. Three recipients developed airway complications (one each with upper, middle, and lower lobe reduction). The 30-day survival rate was 90% and the 1-year survival rate was 70%. One recipient with upper lobe reduction died of septic shock during the perioperative period, one with lower lobe reduction died of airway anastomotic fistula 2 months after surgery, and one with middle lobe reduction died of renal insufficiency 1 year after surgery. All 7 recipients with middle lobe reduction successfully passed the perioperative period, with one case of airway anastomotic stenosis (1/7). The average duration of mechanical ventilation was 71 hours, and the average hospital stay was 26 days. The 30-day survival rate was 7/7, and the 1-year survival rate was 6/7. Conclusions Middle lobe reduction in right lung transplantation surgery has the advantages of low incidence of airway complications, good safety, and minimal loss of lung function, and may be a better right lung volume reduction option with potential for application.

OBJECTIVE: To elucidate the effect of Huanglian-Renshen-Decoction (HRD) on ameliorating type 2 diabetes mellitus by maintaining islet β -cell identity through regulating paracrine and endocrine glucagon-like peptide-1 (GLP-1)/GLP-1 receptor (GLP-1R) in both islet and intestine. METHODS: The db/db mice were divided into the model (distilled water), low-dose HRD (LHRD, 3 g/kg), high-dose HRD (HHRD, 6 g/kg), and liraglutide (400 µ g/kg) groups using a random number table, 8 mice in each group. The db/m mice were used as the control group (n=8, distilled water). The entire treatment of mice lasted for 6 weeks. Blood insulin, glucose, and GLP-1 levels were quantified using enzyme-linked immunosorbent assay kits. The proliferation and apoptosis factors of islet cells were determined by immunohistochemistry (IHC) and immunofluorescence (IF) staining. Then, GLP-1, GLP-1R, prohormone convertase 1/3 (PC1/3), PC2, v-maf musculoaponeurotic fibrosarcoma oncogene homologue A (MafA), and pancreatic and duodenal homeobox 1 (PDX1) were detected by Western blot, IHC, IF, and real-time quantitative polymerase chain reaction, respectively. RESULTS: HRD reduced the weight and blood glucose of the db/db mice, and improved insulin sensitivity at the same time (P<0.05 or P<0.01). HRD also promoted mice to secrete more insulin and less glucagon (P<0.05 or P<0.01). Moreover, it also increased the number of islet β cell and decreased islet α cell mass (P<0.01). After HRD treatment, the levels of GLP-1, GLP-1R, PC1/3, PC2, MafA, and PDX1 in the pancreas and intestine significantly increased (P<0.05 or P<0.01). CONCLUSION HRD can maintain the normal function and identity of islet β cell, and the underlying mechanism is related to promoting the paracrine and endocrine activation of GLP-1 in pancreas and intestine.
