Objective To investigate the association between plasma atherogenic index of plasma(AIP)and metabolism-associated steatotic liver disease(MASLD),and to evaluate the potential value of AIP as a predictive marker for MASLD risk.Methods We enrolled a total of 4 850 health check-up participants from The Second Affiliated Hospital of Xi'an Jiaotong University between June 2021 and May 2023.The participants were divided into quartiles(Q1-Q4)according to their AIP level.Biochemical indicators and MASLD prevalence were compared across groups.Logistic regression,subgroup analysis,and restricted cubic splines(RCS)were used to explore the relationship between AIP and MASLD.Results Among the 4 850 participants,the prevalence of MASLD was 26.08％(1 265/4 850).MASLD prevalence increased across AIP quartiles:4.0％,13.8％,30.8％,and 55.6％in Q1-Q4,respectively(P＜0.001).Compared with Q1,Q2-Q4 groups showed higher proportions of males,BMI,smokers,overweight/obesity,central obesity,prediabetes,hypertension,serum uric acid,and fatty liver index(FLI)(all P＜0.001).Lipid profiles worsened with increased AIP:total cholesterol,triglycerides,and LDL-C increased,while HDL-C decreased(P＜0.001).RCS analysis demonstrated a significant linear relationship between AIP and MASLD risk.After adjusting for confounders,the participants in Q4 had an 8.71-fold higher risk of MASLD than those in Q1(OR:8.71,95％CI:6.20-12.23,P＜0.001).A composite model incorporating AIP,BMI,and FLI showed superior discriminative performance(AUC:0.883,95％CI:0.873-0.892).Interaction analysis suggested that AIP had significant interactions with BMI,hypertension,and prediabetes(P＜0.05).In individuals without these metabolic abnormalities,the association between AIP and MASLD was more pronounced.Conclusion Elevated AIP was significantly associated with an increased risk of MASLD,with a stronger association observed in individuals with normal BMI,blood pressure,and blood glucose levels,suggesting that AIP may serve as a potential indicator for early screening of MASLD.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter，single-arm，retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients，47 were male（79.7%）and 12 were female（20.3%），with a median age of 63.0（56.0，68.0）years and a body mass index of（24.7 ± 3.0）kg/m 2. Surgical procedures included 32 radical prostatectomies，24 partial nephrectomies，one radical nephrectomy，one adrenalectomy，and one ureteral reconstruction. The perioperative indicators，pathological results and postoperative complications were analyzed. The network monitoring data were collected，and the perioperative data of patients，remote system monitoring data and costs were compared between the two communication modes of optical transport network（OTN）and cloud-connect network（CCN）. Results:All 59 remote surgeries were successfully completed，with a mean operative time of（138.0 ± 54.0）minutes，median intraoperative blood loss of 50.0（30.0，100.0）ml and a postoperative hospital stay of 5.0（4.0，6.0）days. No cases required reoperation，Clavien-Dindo grade ≥3 complications，or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing：the shortest latency time（Hefei-Hangzhou，450 km）was（16.59 ± 0.80）ms，while the longest（Harbin-Hangzhou，2 200 km）latency time was（53.31 ± 0.31）ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time［（130.7 ± 70.5）minutes vs.（142.1 ± 42.9）minutes， P = 0.442］，postoperative hospitalization［6.0（4.0，8.0）d vs. 5.0（4.0，6.0）d， P = 0.581］，or readmission rates（0 vs. 0）. However，CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode，with its cost-effectiveness，excellent usability，and multi-point interconnection flexibility，is currently the preferred communication model for telesurgical applications.

OBJECTIVE: To explore the effect of acupuncture therapy on dysphagia in patients with Parkinson's disease. METHODS: This randomized controlled study lasted 42 days and included 112 patients with Parkinson's disease and dysphagia. Participants were randomly assigned to the experimental and control groups (56 cases each group) using the completely randomized design, all under routine treatment. The experimental group was given acupuncture therapy. The primary outcome was Penetration-Aspiration Scale (PAS). The secondary outcomes were (1) Standardized Swallowing Assessment (SSA), and (2) nutritional status including body mass index (BMI), serum albumin, prealbumin, and hemoglobin. Adverse events were recorded as safety indicators. RESULTS: One participant quitted the study midway. There were no significant differences in baseline assessment (P>0.05). After treatment, both groups showed significant improvement in PAS, SSA and nutritional status except for BMI of the control group. There were significant differences between the two groups in the PAS for both paste and liquid, SSA (25.18±8.25 vs. 20.84±6.92), BMI (19.97±3.34 kg/m²vs. 21.26 ±2.38 kg/m²), serum albumin (35.16 ±5.29 g/L vs. 37.24 ±3.98 g/L), prealbumin (248.33 ±27.72 mg/L vs. 261.39 ±22.10 mg/L), hemoglobin (119.09±12.53 g/L vs. 126.67±13.97 g/L) (P<0.05). There were no severe adverse events during the study. CONCLUSION: The combination of routine treatment and acupuncture therapy can better improve dysphagia and nutritional status in patients with Parkinson's disease, than routine treatment solely.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Severe intra-abdominal infections are life-threatening conditions and a significant challenge for surgeons. This article presents a case of an elderly patient with a severe intra-abdominal infection complicated by an anastomotic leak. This patient had experienced prolonged sepsis and multiple surgical traumas. Upon admission to our department, exploratory surgery revealed extensive bowel edema and adhesions, an anastomotic leak, and abdominal contamination with infection. In accordance with the principles of damage control surgery, the anastomotic leak was exteriorized, the abdomen was left open, and continuous intra-abdominal lavage with dual-lumen catheters was implemented to effectively control the infection. Negative pressure wound therapy was used to manage the open abdomen, and a negative pressure-assisted drainage device was used to manage the enteroatmospheric fistula. After granulation of the abdominal wound, split-thickness skin grafting was performed. The enteroatmospheric fistula was converted into an enterocutaneous fistula. A 3D-printed stoma baseplate was used to manage the digestive fistula. Concurrently, enhanced parenteral and enteral nutritional support was provided. Six months later, the patient successfully underwent definitive fistula resection and abdominal wall defect repair.

Objective:To evaluate the efficacy of vacuum sealing drainage (VSD) in the comprehensive management of full-thickness perineal wound dehiscence following pelvic exenteration (PE).Methods:This study employed a descriptive case series design. We retrospectively analyzed the clinical data of 29 patients who developed postoperative perineal wound infections with full-thickness dehiscence after PE. These cases included 16 patients from the Department of General Surgery at Jiangyin People's Hospital (Jiangsu Province) and 13 patients from the Department of Colorectal Surgery at the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital). VSD was applied to manage the dehisced wounds, with outcomes assessed based on wound healing time, complications, and follow-up data.Results:A total of 29 patients were included in the study. The operative time for PE was (498 ± 83) minutes. Among them, 23 patients underwent combined sacrococcygeal resection. The median number of VSD devices used was 28 (22, 39). The postoperative perineal wound healing time was 95 (82, 110) days in patients who underwent combined sacrococcygeal resection, 74 (63, 89) days in those without sacrococcygeal resection, 93 (79, 102) days in those treated with simple pelvic-abdominal isolation using a biological basement membrane mesh and 76 (60, 91) days in those who received combined pelvic packing with a pedicled omental flap. All patients uniformly developed Clavien-Dindo grade III complications at 2 weeks postoperatively, manifesting as perineal wound infection and dehiscence, which were successfully managed with VSD therapy. Subsequent evaluation identified delayed (>30 days) grade III complications, including enterocutaneous (3 cases) and urinary (2 cases) fistulae, all requiring surgical revision. All patients completed the follow-up at 6 months postoperatively. Three patients still presented with minimal exudate from the perineal wound, which resolved after standardized wound care and packing with alginate silver ion dressings. Four cases (13.8%) developed stoma high-output syndrome, which improved after oral medication. Eight patients (27.6%) developed adhesive intestinal obstruction, which improved with conservative treatment.Conclusions:VSD demonstrates unique advantages in managing complex wounds. For full-thickness perineal wound dehiscence after PE, VSD is a safe and effective therapeutic strategy.

Objective To investigate the association between plasma atherogenic index of plasma(AIP)and metabolism-associated steatotic liver disease(MASLD),and to evaluate the potential value of AIP as a predictive marker for MASLD risk.Methods We enrolled a total of 4 850 health check-up participants from The Second Affiliated Hospital of Xi'an Jiaotong University between June 2021 and May 2023.The participants were divided into quartiles(Q1-Q4)according to their AIP level.Biochemical indicators and MASLD prevalence were compared across groups.Logistic regression,subgroup analysis,and restricted cubic splines(RCS)were used to explore the relationship between AIP and MASLD.Results Among the 4 850 participants,the prevalence of MASLD was 26.08％(1 265/4 850).MASLD prevalence increased across AIP quartiles:4.0％,13.8％,30.8％,and 55.6％in Q1-Q4,respectively(P＜0.001).Compared with Q1,Q2-Q4 groups showed higher proportions of males,BMI,smokers,overweight/obesity,central obesity,prediabetes,hypertension,serum uric acid,and fatty liver index(FLI)(all P＜0.001).Lipid profiles worsened with increased AIP:total cholesterol,triglycerides,and LDL-C increased,while HDL-C decreased(P＜0.001).RCS analysis demonstrated a significant linear relationship between AIP and MASLD risk.After adjusting for confounders,the participants in Q4 had an 8.71-fold higher risk of MASLD than those in Q1(OR:8.71,95％CI:6.20-12.23,P＜0.001).A composite model incorporating AIP,BMI,and FLI showed superior discriminative performance(AUC:0.883,95％CI:0.873-0.892).Interaction analysis suggested that AIP had significant interactions with BMI,hypertension,and prediabetes(P＜0.05).In individuals without these metabolic abnormalities,the association between AIP and MASLD was more pronounced.Conclusion Elevated AIP was significantly associated with an increased risk of MASLD,with a stronger association observed in individuals with normal BMI,blood pressure,and blood glucose levels,suggesting that AIP may serve as a potential indicator for early screening of MASLD.
