Objective:To explore a simple emergency management method for elderly patients with sigmoid volvulus.Methods:The clinical data of 22 elderly patients (>70 years) with sigmoid volvulus from January 2020 to March 2024 in the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. All patients were treated with a self-made simple closed-loop enema decompression kit. The abdominal circumference, white blood cell count and C-reactive protein (CRP) before treatment and 12 h after tube placement were measured. The patients were followed for 3 months, and the recurrence was recorded. The key indexes on recurrence, including age, American Society of Anesthesiologists (ASA) classification and procedure time, were compared. Pearson correlation analysis was used to examine the relationship between age, procedure time, pain level and gas/stool output within 30 min after tube placement.Results:All 22 patients successfully underwent transanal tube decompression. The procedure time ranged from 1 to 15 min. The gas and stool output within 30 min after tube placement was 600 to 2 100 ml, The rectal tube was retained for 2 to 6 d. Compared with before treatment, the abdominal circumference, white blood cell count and CRP 12 h after tube placement were significantly lower: (85.9 ± 9.6) cm vs. (94.5 ± 10.2) cm, (9.2 ± 2.1) ×10 9/L vs. (11.4 ± 2.5) ×10 9/L and (27.8 ± 22.6) mg/L vs. (46.2 ± 38.9) mg/L, and there were statistical differences ( P<0.01). Four patients underwent elective surgery, while 18 were discharged smoothly after tube removal. No death occurred within 1 month after treatment. Five patients experienced recurrence 3 months after treatment, all were successfully retreated using the same method and discharged. There were no statistical differences in recurrence rates between aged ≥80 years and aged < 80 years patients, ASA class ≥ Ⅳ and ASA class Ⅲ patients, or procedure times ≤5 min and procedure times >5 min patients ( P>0.05). The gas/stool output within 30 min after tube placement was positively correlated with pain level (moderate/severe vs. mild) before tube placement ( r = 215.50, P = 0.015), but showed no significant correlation with age or procedure time ( P>0.05). Conclusions:The self-made simple closed-loop enema decompression kit provides a straightforward, economical and minimally invasive emergency treatment method for elderly patients with sigmoid volvulus. For patients at very high surgical risk, this kit can achieve decompression and volvulus reposition, even in cases of recurrence.

Objective:To investigate the clinical value of right-sided overlap and single-flap valvuloplasty (ROSF) in Da Vinci robotic proximal gastrectomy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 12 patients who underwent ROSF in Da Vinci robotic proximal gastrectomy at The Affiliated Hospital of Xuzhou Medical University from September 2023 to May 2024 were collected. There were 7 males and 5 females, aged 62(range, 35?75)years. Observation indicators: (1) surgical conditions; (2) postoperative pathological results; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and mea-surement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers. Results:(1) Surgical conditions. All patients successfully completed the surgery, without conversion to laparotomy. The operation time of 12 patients was (236±24)minutes. The time of single-layer fabrication and anastomosis was (105±28)minutes. The volume of intra-operative blood loss was (36±19)mL. Time to postoperative first fluid food intake was (3.5±1.1)days. The amylase levels in the abdominal drainage fluid on postoperative days 1, 2, and 3 were (321±121)U/L, (225±97)U/L, and (85±22)U/L, respectively. Time to postoperative drainage tube removal was (5.3±1.5)days. Duration of postoperative hospital stay was (7.6±1.1)days. All 12 patients had no anasto-motic related complications such as anastomotic leakage, anastomotic bleeding, anastomotic stenosis, and had no functional complications such as gastric emptying disorders or gastroesophageal reflux after surgery. (2) Postoperative pathological results. The distance of the proximal tumor margin of the 12 patients was (1.8±1.1)cm. The distance of distal margin was (5.7±2.1)cm. Number of lymph node dissected was 31.0(range, 22.0?45.0). Number of positive lymph node dissected was 3.4±2.4. Number of lymph node dissected from the pancreatic superior margin was 14.7±4.3. Results of postoperative pathological examination in the 12 patients showed 8 cases of Ⅰ stage, 3 cases of Ⅱ stage, 1 case of Ⅲ stage of the TNM staging. (3) Follow-up. All 12 patients were followed up for 6 (range, 3?24)months. During the follow-up period, all 12 patients had no local tumor recurrence or distant metastasis. All 12 patients had no complications such as anastomotic leakage, anastomotic bleeding, or anastomotic stenosis, and did not experience symptoms of gastroesophageal reflux such as heartburn or vomiting.Conclusion:The ROSF in Da Vinic robotic proximal gastrectomy is safe and feasible.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

To investigate the transcriptionally regulatory mechanism of the senp8 promoter in yellow cat-fish(Pelteobagrus fulvidraco);this study used P.fulvidraco as the research subject.Dual-luciferase re-porter assay and electrophoretic mobility shift assay were employed to analyze the functional activity of the promoter;coupled with in vivo experiments.The results indicated that the 2 045 bp senp8 promoter se-quence contained key transcription factor binding sites such as SP1;TATA-Box;CCAAT-Box;SREBP1;PPARα;and PPARγ.The binding sites of SREBP1(-901/-910 bp);PPARα(-1 291/-1 308 bp);and PPARγ(-1 292/-1 306 bp)in the senp8 promoter positively regulate its activity;and oleic acid or palmitic acid promote this binding.Furthermore;high-fat feeding promoted the expression of the senp8 gene and its protein in the liver of P.fulvidraco;oleic acid or palmitic acid treatment significantly en-hanced the activity of the senp8 promoter;and this enhancement could be achieved through the regulatory effects of SREBP1;PPARα;and PPARγ response elements.Additionally;high-fat feeding influenced the mRNA and protein expression levels of genes related to deSUMOylation modification in the liver of P.fulvidraco.This study provides new insights into the relationship between deSUMOylation modification and the regulation of lipid metabolism in the vertebrates.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution. The third is to achieve deep adaptation between generative intelligence and the entire process of patient medical treatment. In this project, we have developed assistant tools such as intelligent inquiry, intelligent diagnosis and recognition, intelligent treatment plan generation, and intelligent assisted medical record generation to improve the safety, quality, and efficiency of the diagnosis and treatment process. This study introduces the content of a full-process disease diagnosis and treatment assistance system, aiming to provide references and insights for the digital transformation of the healthcare industry.

OBJECTIVE: Circadian rhythm disruption (CRD) is a risk factor that correlates with poor prognosis across multiple tumor types, including hepatocellular carcinoma (HCC). However, its mechanism remains unclear. This study aimed to define HCC subtypes based on CRD and explore their individual heterogeneity. METHODS: To quantify CRD, the HCC CRD score (HCCcrds) was developed. Using machine learning algorithms, we identified CRD module genes and defined CRD-related HCC subtypes in The Cancer Genome Atlas liver HCC cohort (n = 369), and the robustness of this method was validated. Furthermore, we used bioinformatics tools to investigate the cellular heterogeneity across these CRD subtypes. RESULTS: We defined three distinct HCC subtypes that exhibit significant heterogeneity in prognosis. The CRD-related subtype with high HCCcrds was significantly correlated with worse prognosis, higher pathological grade, and advanced clinical stages, while the CRD-related subtype with low HCCcrds had better clinical outcomes. We also identified novel biomarkers for each subtype, such as nicotinamide n-methyltransferase and myristoylated alanine-rich protein kinase C substrate-like 1. CONCLUSION We classify the HCC patients into three distinct groups based on circadian rhythm and identify their specific biomarkers. Within these groups greater HCCcrds was associated with worse prognosis. This approach has the potential to improve prediction of an individual's prognosis, guide precision treatments, and assist clinical decision making for HCC patients.

OBJECTIVE: To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development. METHODS: A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected. RESULTS: Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ ² = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006). CONCLUSIONS Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.
