Cirrhotic portal hypertension is a clinical syndrome caused by persistently elevated portal venous pressure due to liver cirrhosis and can lead to a series of complications， among which esophagogastric variceal bleeding has become one of the most severe complications due to sudden onset and a high mortality rate. Since the release of Expert consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension （2019 edition）， significant advances have been achieved in this field in China and globally. In order to formulate an expert consensus aligned with the situation of China， Chinese Society of Surgery， Chinese Medical Association organized and compiled Expert Consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension （2025 edition）. This article elaborates on the key updates in the new edition and explores the major differences between the old and new editions， in order to enhance the understanding of the new edition among clinicians and provide a reference for clinicians in clinical work.

ObjectiveTo analyze the influencing factors for recurrence in successfully treated pulmonary tuberculosis patients with isoniazid-resistant and rifampicin-sensitive in Shaoxing City, Zhejiang Province. MethodsData on general demographic information, treatment information and drug susceptibility test results for pulmonary tuberculosis patients admitted to the designated tuberculosis medical institutions and registered in the tuberculosis information management system was collected in Shaoxing City from January 2011 to August 2024. A total of 428 patients with isoniazid resistance (including isoniazid single resistance and multiple resistance) but who were successfully treated were included in the study. Information for the recurrence after successful treatment of the patients was analyzed. The Cox proportional hazards models were used to analyze the influencing factors of recurrence in patients. ResultsAmong the 428 successfully treated patients included in the study, 31 cases (accounting for 7.24%) had recurrence by the end of the observation period, with a recurrence rate density of 1.31 per 100 person-years and a median recurrence time of 0.99 (0.08, 8.27) years. Among the relapsed population, 51.61% of the patients relapsed within one year after successful treatment. 77.42% of the patients relapsed within two years after successful treatment. Multivariate Cox regression analysis showed that when isoniazid resistance was discovered, the diagnosis classification of relapse (HR=4.115, 95%CI: 1.734‒9.767) and positive 0-month sequence smear (HR=4.457, 95%CI: 1.053‒18.866) were risk factors for recurrence after successful treatment in patients. ConclusionRegular follow-up should be strengthened for at least two years after the successful treatment of isoniazid-resistant pulmonary tuberculosis patients. Special attention should be paid to the treatment effect and regular re-examination and monitoring after the end of the treatment course of isoniazid-resistant pulmonary tuberculosis patients who have been re-treated and were sputum smear positive at baseline, so as to prevent recurrence and disease progression in high-risk populations.

OBJECTIVE: To observe the protective effect of Fisetin on sepsis-associated brain injury and explore its possible mechanism from the perspective of ferroptosis. METHODS: Sprague-Dawley (SD) rats (6-8-week-old male) were randomly divided into three groups: sham operation group (Sham group), colonic ligation and puncture (CLP) induced sepsis model group (CLP group) and Fisetin preprocessing group (CLP+Fisetin group), with 18 rats in each group (12 for observing survival rate and 6 for indicator testing). The CLP+Fisetin group was given Fisetin solution 50 mg×kg^-1×d^-1 by gavage continuously for 5 days before CLP, with dimethyl sulfoxide (DMSO) as the solute, while Sham group and CLP group were given the same dose of DMSO. The model was established at 2 hours after the last gavage. The general condition of each group of rats were observed, and the 10-day mortality were record. The behavioral testing (new object recognition experiment, elevated cross maze experiment) were performed after 7 days of modeling. After 24 hours of modeling, nerve reflex scoring was performed, and then the rats were euthanized and brain tissue was collected. The pathological changes of brain tissue were observed under a microscope by hematoxylin-eosin (HE) staining, the deposition of iron ion in brain tissue was observed by Prussian blue staining. The content of iron in brain tissue was determined by tissue iron kit, and the content of malondialdehyde (MDA) in brain tissue was determined by colorimetry. The expressions of tumor necrosis factor-α (TNF-α), neuron damage marker S100β, nuclear factor E2-related factor 2 (Nrf2), heme oxygenases-1 (HO-1) and glutathione peroxidase 4 (GPX4) were detected by Western blotting. RESULTS: On day 10 post-operation, 12, 3, and 7 animals survived in the Sham group, CLP group, and CLP+Fisetin group, respectively. Compared with the Sham group, rats in the CLP group showed significantly decreased nerve reflex score, new object discrimination index and open arm dwell time. HE staining showed arranged disorderly of neuronal cells, cytoplasm deep staining, nuclear condensation, unclear structures, neuron loss, and significant inflammation in the hippocampus in the hippocampus. Prussian blue staining showed iron ion deposition in the brain tissue. The contents of iron and MDA in brain tissue were elevated, and the expressions of TNF-α and S100β were up-regulated, while the expressions of Nrf2, HO-1, and GPX4 were down-regulated. Compared with the CLP group, the CLP+Fisetin group showed significantly increased neurological reflex score (7.33±1.15 vs. 4.67±1.53), improved new object discrimination index (0.44±0.02 vs. 0.32±0.04), and longer open arm dwell time (minutes: 78.33±9.29 vs. 41.15±9.64). Neuronal cells in the hippocampus were more organized, with less cytoplasmic staining, nuclear condensation, reduced neuronal loss, and fewer inflammatory cells. Iron ion deposition was reduced, and the contents of iron ions and MDA in brain tissue were decreased [iron ion (μg/g): 151.27±14.90 vs. 224.69±17.64, MDA (μmol/g): 470.0±44.3 vs. 709.3±65.4]. The expressions of TNF-α and S100β were significantly decreased (TNF-α/GAPDH: 0.651±0.060 vs. 0.896±0.022, S100β/GAPDH: 0.685±0.032 vs. 0.902±0.014), while the expressions of Nrf2, HO-1, and GPX4 were significantly increased (Nrf2/GAPDH: 0.708±0.108 vs. 0.316±0.112, HO-1/GAPDH: 0.694±0.022 vs. 0.538±0.024, GPX4/GAPDH: 0.620±0.170 vs. 0.317±0.039). All differences were statistically significant (all P < 0.05). CONCLUSION Fisetin pretreatment can inhibit ferroptosis and reduce sepsis-associated brain injury by Nrf2/HO-1/GPX4 pathway.

Objective:To compare the clinical application of the anterolateral thigh perforator flap (ALTPF) and the calf pedicled propeller perforator flap (PPPF) in reconstruction of soft tissue defect of foot and ankle.Methods:A retrospective observational study was conducted. From March 2013 to June 2019, 48 patients with soft tissue defect around ankle and in foot were reconstructed with ALTPF and PPPF in the Department of Orthopaedics, 920th Hospital of the Joint Logistic Support Force, People's Liberation Army of China. According to the types of flap, the patients were divided into 2 groups: ALTPF group (21 patients,13 males and 8 females, aged 16-67 years, mean 38.71 years±15.30 years. Donor sites were all directly sutured.) and PPPF group (27 patients, 12 males and 15 females, aged 12-69 years, mean 35.18 years±13.96 years. Five cases in the donor site required partial skin grafting, and the rest 22 cases were repaired by directly suture.). The wound size of the former was 5 cm×6 cm-15 cm×18 cm, and at 2 cm×3 cm-14 cm×17 cm for the latter. The surgical time and flap size of the 2 groups were recorded during the surgery. The survival and complications of the flap were observed, and the days of hospital stay were recorded after surgery. Follow-ups were conducted by outpatient clinic and via telephone and WeChat interviews. The colour, texture, appearance, donor scar, complications and thinning of the flap were observed during the follow-up. The ankle function was evaluated according to the score of American Orthopaedic Foot and Ankle Society (AOFAS), and the donor scar was evaluated according to the score of Vancouver Scar Scale (VSS). SPSS 22.0 statistical software was used for data analysis, and P<0.05 was considered statistically significant. Results:The surgical time for the ALTPF group was 118-203 (154.71±25.42) min, and that for the PPPF group was 52-92 (72.78±10.04) min. The size of the flap in the ALTPF group was 5 cm×8 cm-8 cm×18 cm (75.00 cm 2±8.69 cm 2), while it was 3 cm×7 cm-7 cm×17 cm (53.56 cm 2±19.49 cm 2) in the PPPF group. In the ALTPF group, 3 flaps had vascular complications within 24 hours after surgery, which survived after exploration and thrombectomy. Partial necrosis occurred in 1 flap. The rest 17 flaps survived uneventfully. In the PPPF group, 2 flaps had partial necrosis due to infection and they healed after dressing changes, 3 flaps had venous occlusion and survived after phlebotomy, partial suture removal and massage. The rest 22 flaps in 2 groups survived uneventfully. The postoperative days of hospital stay for the ALTPF group was 6-14 (8.71±2.03) days, and that was 4-12 (6.03±2.16) days in the PPPF group. Flap thinning was performed on 19 flaps in the ALTPF group and 2 in the PPPF group. Follow-up was performed for 7 to 21 months. All the flaps were good in colour, shape and texture. All donor sites healed well. At the final follow-up, 19 patients achieved ankle function of excellent, 1 of good and 1 of fair in the ALTPF group, and 21 patients achieved ankle function of excellent, 4 of good and 2 of fair in the PPPF group, according to the AOFAS. According to the VSS, scores of donor site scar was rated 4-8 (6.33±1.35) points for the ALTPF group, and 3-10 (5.92±1.80) points for the PPPF group. Statistical analysis showed no significant differences between the 2 groups in terms of early postoperative complications, flap survival rate, ankle function, and VSS scores ( P>0.05). However, there were statistically significant differences between the 2 groups in terms of surgical time, hospital stay, flap size, and the number of flap thinning ( P<0.05). Conclusion:Both ALTPF and PPPF have good clinical effects in reconstruction of soft tissue defect of foot and ankle. For small to medium-sized wounds, PPPF is the preferred choice due to the advantages in surgical time and postoperative hospital stay. For larger wounds, the ALTPF is the first choice with multiple surgery.

Objective:To investigate the correlation between hearing loss and microvascular complications in diabetes.Methods:This cross-sectional study conducted the data from 572 patients with diabetes hospitalized in the Endocrinology Department of the General Hospital of Southern Theater Command from September 2022 to July 2023. All participants underwent electrical audiometry and acoustic immittance in the ENY department. Based on the audiometric results, participants were categorized into normal hearing group and hearing loss group. Additionally, 572 non-diabetic patients from the outpatient department were enrolled as the non-diabetic group. The general information and laboratory results were collected and compared using t test, rank sum test or χ2 test. Binary logistic regression analysis was used to evaluate the association of diabetic hearing loss with diabetic kidney disease(DKD), diabetic retinopathy (DR), and diabetic peripheral neuropathy (DPN). Results:Among 572 patients with diabetes, 429 suffered from hearing loss and 143 were normal. χ2 test showed significant differences in combined DKD and DPN between two groups, but not in DR. Multivariate binary logistic regression analysis identified DKD and DPN as risk factors for hearing loss, but no correlation was found with DR. Conclusion:Diabetic patients with DKD or DPN should be monitored for potential hearing loss. Early screening and treatment are crucial to prevent severe hearing impairment.

Objective:To develop a grading system for necrosis of pedicled flaps in reconstruction of foot and ankle, and to verify its effectiveness and repeatability.Methods:A retrospective observational study was conducted. A total of 40 necroses of foot and ankle pedicled flaps were selected by 2 senior surgeons based on the flap surgery performed by the same surgical group in Department of Orthopaedic Surgery, the 920 Hospital of Joint Logistic Support Force of PLA from January 2010 to January 2022. A grading system for pedicled flap necrosis was proposed by a working group and the 40 necrotic flaps were graded. The coincidence rate was calculated to evaluate the effectiveness of the grading system through correlation studies between grading and clinical treatment. One photo of a typical postoperative necrotic flap was collected from each of the 40 flaps. Then 5 extramural surgeons were asked to grade the necroses shown on the photos according to the proposed grading system. Moreover, weighted Kappa analysis was performed on the results of proposed grading system and also on the standard grading currently in use, to evaluate the repeatability of the proposed grading system. Evaluated data were expressed by Mean±SD, and the coincidence rate was expressed by percentage. The reproducibility was studied by weighted Kappa analysis.Results:Of the 40 necrotic flaps, 7 flaps were classified in Grade I, 16 in Grade Ⅱ, 12 in Grade Ⅲ and 5 in Grade IV. In comparison with the actual treatment methods, the overall coincidence rate of the grading system was 92.5%. It indicated that the proposed grading system could effectively guide the selection of a treatment procedure. The average weighted Kappa coefficient of surgeons was at 0.628 with a 95% confidence interval (95%CI) between 0.460-0.796, which was strongly consistent with the standard of the grading system currently in use.Conclusion:The grading system for necrosis of pedicled flap in reconstruction of foot and ankle proposed in this study is simple and clear. It is able to effectively guide the treatment of flap necrosis. The preliminary validation shows that the classification system has good repeatability.

Objective To compare the safety and efficacy of flexible terminal suction ureteral access sheath(FTS-UAS)and negative pressure ureteral access sheath(NPUAS)in flexible ureteroscopic lithotripsy with holmium laser in treatment of renal calculi less than 2 cm in diameter.Methods A total of 68 patients(largest diameter of stone＜2 cm)with renal calculi treated in Yangjiang Hospital Affiliated to Guangdong Medical University during Nov.2022 and Aug.2023 were divided into FTS-UAS group(n=34)and NPUAS group(n=34)according to different surgical methods.The perioperative parameters and stone-free rate(SFR)were compared between the two groups.Results The average SFR on the first day after operation was significantly higher in the FTS-UAS group than in the NPUAS group[85.3％(29/34)vs.61.8％(21/34),P=0.028].The operation time was significantly lower in the FTS-UAS group than in the NPUAS group[(65.85±13.16)min vs.(75.59±20.21)min,P=0.022].For lower calyceal renal calculi,the SFR was significantly higher in the FTS-UAS group than in the NPUAS group[82.4％(14/17)vs.43.8％(7/16),P=0.032].One month after operation,the SFR was higher in the FTS-UAS group than in the NPUAS group[94.1％(32/34)vs.85.3％(29/34),P=0.452].There were no significant differences in hemoglobin reduction,serum creatinine level,postoperative complications,hospital stay and hospitalization costs between the two groups(P＞0.05).Conclusion FTS-UAS in flexible ureteroscopic lithotripsy can shorten the operation time and improve stone-clearance rate,which is safe,effective,and worthy of clinical promotion.

Objective To explore the effectiveness of quantitative reward points management in performance related pay to the staff in central sterile supply department(CSSD)and offer the insights into the staff pay.Methods A comparison method of pre-and post-control was employed in this study.The staff who received seniority related pay system in CSSD of the hospital from January to December 2020 served as a control group,while the same group of staff in the same department who received the pay based on quantitative reward points management from January to December 2021 served as an observation group.In the control group,the staff received equal pay.However in the observation group,a quantitative reward points system was applied,and the staff pays were dependent upon the reward points derived from technique proficiency,quality and efficiency of work and workload.The two groups were compared in terms of working efficiency,occurrence of errors(such as missing of instruments in sterilised packages,errors in package categories,package labels,collection and delivery items,and errors in operation of information system),and the satisfaction levels evaluated by user departments.Result After implementation of the system of quantitative reward points management,the working efficiency of CSSD staff and the satisfaction levels of the user departments were both significantly improved,while the errors were significantly dropped(P＜0.05).Conclusion Application of the quantitative reward points management in CSSD can enhance work incentive in CSSD staff,leading to an improvement in working efficiency and quality.
