ObjectiveThis study aims to explore the mechanism by which Yishen Huoxue Tongqiao Formula improves metabolism-neuroplasticity and treats unilateral vestibular labyrinth destruction by regulating the metabolic balance of glutamate （Glu）/γ-aminobutyric acid （GABA）. Methods48 Sprague-Dawley （SD） adult rats were randomly divided into the sham operation group， model group， Yishen Huoxue Tongqiao Formula groups with low， medium， and high doses （9.20， 18.39， 36.78 g·kg^-1）， and betahistine group （1.62 mg·kg^-1）. A unilateral vestibular labyrinth destruction （vestibular dysfunction） model was established by intratympanic injection of chloroform into the right ear， while the control group received intratympanic injection of normal saline. Drugs were administered once daily for seven consecutive days. During the period， behavioral tests were performed to evaluate the behaviors of rats after unilateral vestibular labyrinth destruction. Hematoxylin-eosin （HE） staining and Nissl staining were used to observe the neuronal morphology in the medial vestibular nucleus. Golgi staining was employed to assess the number of dendritic spines of neurons in the medial vestibular nucleus. Ultra-performance liquid chromatography-tandem mass spectrometry （LC-ESI-MS/MS） was utilized to detect Glu/GABA. Immunofluorescence and immunohistochemistry were used to detect the expressions of neuronal nuclei （NeuN）， growth-associated protein 43 （GAP-43）， and glial fibrillary acidic protein （GFAP）. Western blot and real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） were applied to determine the expressions of glutamate-immunoreactive （Glu-IR）， GABA， GFAP， postsynaptic density protein 95 （PSD-95）， and GAP-43. ResultsCompared with the sham operation group， the model group presented with head deviation， balance disorder， increased tail suspension score， nuclear consolidation of medial vestibular nerve neurons， and decreased Nissl bodies （P<0.01）. The number of dendritic spines in neurons and NeuN-positive cells decreased. The content of Glu decreased. The content of GABA increased （Glu/GABA decreased）. The expression of GAP-43 was down-regulated， and GFAP was up-regulated （P<0.05， P<0.01）. The expressions of Glu-IR， PSD-95， and GAP-43 proteins， as well as Glu-IR mRNA decreased， while the expressions of GABA and GFAP proteins and mRNA increased （P<0.05， P<0.01）. Compared with those in the model group， the head deviation， imbalanced behavior， and tail suspension scores in each treatment group decreased， with alleviated neuronal injury and recovered Nissl bodies （P<0.01）. The number of dendritic spines of neurons increased， and the number of NeuN-positive cells rebounded. The content of Glu increased， and the content of GABA decreased （Glu/GABA increased）. GFAP was down-regulated， and GAP-43 was up-regulated （P<0.05， P<0.01）. The expressions of Glu-IR， PMD-95， and GAP-43 proteins， as well as Glu-IR mRNA increased， while the expressions of GABA and GFAP proteins and mRNA decreased. The effect was more significant in the high-dose group （P<0.01）. ConclusionThe Yishen Huoxue Tongqiao Formula can alleviate vestibular dysfunction， and its mechanism may be associated with regulating the metabolic balance of Glu/GABA， mitigating neural damage， improving synaptic plasticity （promoting GAP-43 expression and inhibiting GFAP expression）， and facilitating vestibular compensation.

Objective:This study aims to analyze historical trends and predict future trends of disability-adjusted life years (DALYs) attributable to high BMI for osteoarthritis (OA) in China. OA is a common chronic degenerative joint disease, with high body mass index (BMI) being a significant risk factor. in China.Methods:Based on the Global Burden of Disease (GBD) 2021 database, we analyzed trends in high-BMI-attributable OA. The ASR of hogh-BMI-attributable OA DALYs increased from DALYs in China from 1990 to 2021. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Age-standardized rates (ASR) and estimated annual percentage changes (EAPC) were calculated to assess trend changes of trends. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Chi-square tests were used to compare differences in high BMI attribution proportions between regions and years.Results:From 1990 to 2021, China′s OA DALYs increased from 1.829 to 5.327 million, with the proportion attributable to high BMI rising from 13.47% to 21.86% ( χ2=60 527.25, P<0.001). The ASR of high-BMI-attributable to OA increased from 27.4 (-2.2, 81.5) per 100,000 to 53.0 (-4.7, 150.7) per 100 000, with an EAPC of 2.48% [95% (uncertainty interval, UI): 2.35, 2.62]. In 2021, females showed significantly higher ASR (69.2 per 100 000) than males (36.1 per 100 000). Knee OA (ASR: 50.5/100 000) demonstrated substantially higher burden than hip OA (ASR: 2.5/100 000). Age effect analysis showed DALYs peaked at ages 80~90; period effect indicated accelerated growth after 2005; cohort effect showed a U-shaped trend with the 1990 birth cohort having the highest relative risk (approximately 3.0). Projections indicated that up to 2046, total OA DALYs will reach approximately 2.39 million with an ASR of about 71, showing more significant growth among females (ASR reaching 100). Conclusion:High-BMI-attributable to OA DALYs in China shows a significant upward trend, and is expected to continue. This trend is more pronounced among females and elderly populations than males, highlighting the urgency of implementing preventive measures for high-risk groups, particularly in weight management.

To examine the evolution of surgical techniques and trends in overall inpatient burden for pediatric adenoidectomy in Beijing tertiary hospitals from 2013 to 2022. A retrospective observational study was conducted using the regional health information platform of Beijing. Data from children aged ≤14 years who underwent adenoidectomy between 2013 and 2022 were extracted, including total hospitalization cost, length of stay(LOS), surgical material cost, surgical fee, operative technique, perioperative antimicrobial drugs cost, coagulation factor cost, and blood transfusion cost. The Mann-Kendall trend test was used to assess temporal changes in total hospitalization expenses and the structure of cost components. The results showed that over the 10-year period from 2013 to 2022, a total of 25 989 children underwent adenoidectomy in tertiary hospitals. The proportion of children aged ≤6 years increased from 59.83% to 76.11%, showing a significant upward trend ( Z=2.15, P=0.032). Only one case required surgical hemostasis due to postoperative bleeding. During the ten-year period, the median hospitalization cost for adenoidectomy in tertiary hospitals was ￥12 425.82 (￥11 307.43, ￥14 955.42).Overall hospitalization cost demonstrated a fluctuating downward pattern, decreasing from ￥15 229.73 in 2013 to ￥13 927.52 in 2022, this declining trend was not statistically significant( Z=-0.54, P=0.592). In contrast, the surgical costs showed an upward trend over the decade increasing from ￥1 856.22 in 2013 to ￥3 726.45 in 2022, which was statistically significant ( Z=3.22, P=0.001), while the cost of surgical materials showed no significant increase ( Z=1.79, P=0.074).Concurrently, the average LOS decreased remarkably from 10.56 days in 2013 to 3.26 days in 2022 ( Z=-3.94, P<0.001). The cost of perioperative antimicrobial drugs decreased ( Z=-3.94, P<0.001), while the cost of coagulation factors and blood transfusion remained unchanged ( Z=0.54, P=0.592; Z=0.56, P=0.578). Comparison between 2013-2017 and 2018-2022 showed a significant increase in the use of coblation from 28.9% to 42.5% ( χ2=638.7, P<0.001).Furthermore, in the coblation group, total hospitalization cost decreased by 27.73%, surgical cost increased by 94.98%, surgical material cost decreased by 10.33%, LOS shortened by 56.24%, and antimicrobial drug cost increased by 43.03%. In contrast, the non-coblation group showed a 23.94% increase in total hospitalization cost, a 57.08% increase in surgical procedure cost, a 33.88% increase in material cost, and a 30.14% reduction in LOS and a 26.0% decrease in antimicrobial drugs cost. In conclusion,from 2013 to 2022, total hospitalization cost for pediatric adenoidectomy in Beijing tertiary hospitals remained stable. Compared to non-coblation techniques, coblation was associated with a shorter LOS, lower total costs, a higher proportion of surgical fees, and a decreased proportion of material costs, without a significant increase in overall healthcare costs.

The da Vinci Surgical System provides surgeons with a three-dimensional image view with greater clarity, which improves surgical precision, particularly in confined surgical spaces. Compared to laparoscopic surgery, robotic surgery has a shorter learning curve and may be a better choice for surgeons. However, some surgeons are susceptible to laparoscopic experience when performing robotic surgery, which can diminish the advantages of the robotic system. We discussed some key issues such as indications, use of energy instruments, surgical approach, lymph node dissection, and digestive tract reconstruction, from the habit of laparoscopic surgery, in light of our team's experience with robotic radical gastric cancer surgery and the latest literature, in order to help beginners better understand the robotic surgical system.

Objective:To investigate the clinical characteristics, postoperative complications, and risk factors for pouchitis in surgical patients with ulcerative colitis (UC).Methods:This was a retrospective observational study. The clinical data of 336 UC patients who had undergone surgical treatment at the Inflammatory Bowel Disease Center of the Department of General Surgery, Jinling Hospital Affiliated to Nanjing University Medical School from February 2014 to February 2024 were enrolled. The study patients were stratified into 2014-2019 ( n = 158) and 2020–2024 groups ( n = 178), these being the periods before and after biologics were covered for treatment of UC by national insurance in China in 2020. Clinical characteristics and surgical complications were analyzed and compared between the 2014-2019 and 2020-2024 groups. Multivariable logistic regression was performed to identify the risk factors associated with pouchitis in UC patients undergoing total proctocolectomy with ileal pouch-anal anastomosis (TPC-IPAA). Results:The study cohort comprised 336 UC patients, 193 (57.4%) of whom were men. The median preoperative disease course was 48.0 months and the mean age at colectomy was 46.4±15.4 years. TPC-IPAA had been performed on 275 patients (81.8%), 129 in the 2014-2019 group and 146 in the 2020-2024 group. Sixty-one patients had undergone total or subtotal colectomy, 29 in the 2014-2019 group and 32 in the 2020-2024 group. 262 (78.0%) UC patients underwent surgery due to medical refractory. Ninety-nine (29.5%) had used biopharmaceuticals within 2 months prior to surgery, 63 (18.8%) of them having received infliximab. A smaller proportion of patients had undergone surgery for UC that was refractory to medications in the 2020–2024 group than in the 2014–2019 group (73.0% [130/178] vs. 83.5% [132/158], χ 2=5.384, P=0.020), the patients were older at colectomy (48.0±15.4 years vs. 44.6±15.2 years, t=-2.008, P=0.045), the body mass index was higher (20.2±3.1 kg/m 2 vs. 19.4±3.2 kg/m 2, t=-2.201, P=0.028), the Mayo score prior to surgery was lower ( M[ Q1, Q3]: 11.0 [9.2, 12.0 points] vs. 12.0 [11.0, 12.0) points, Z=-4.242, P=0.001), the rate of Charlson Comorbidity Index ≥ 3 scores was higher (27.0% [48/178] vs. 17.1% [27/158], χ 2=5.384, P=0.020), a greater percentage of patients had received biologics prior to surgery (41.0% [73/178) vs. 16.5% [26/158], χ 2=24.285, P<0.001), and intraoperative blood loss was greater ( M[ Q1, Q3]: 100.0 [100.0, 150.0] ml vs. 50.0 [30.0, 100.0] ml, Z=-7.054, P<0.001) despite the operation time being shorter (253.8±74.6 minutes vs. 315.2±96.8 minutes, t=6.265, P<0.001). Among the 275 patients undergoing TPC-IPAA, 95 (34.6%) had early complications (within 30 days after surgery), 20 (7.3%) of which were Clavien-Dindo Grade III–IV complications. Among these patients, 50 (18.2%) had ileus or small bowel obstruction, 11 in the 2014-2019 group and 39 in the 2020-2024 group; this difference is statistically significant (χ 2=15.225, P<0.001). Ninety-one patients (33.1%) had late complications (more than 30 days after surgery), 75 (27.3%) being pouchitis (36 in the 2014-2019 group and 39 in the 2020-2024 group); this difference is not statistically significant (χ 2=0.049, P=0.824). Five patients (1.8%) had undergone pouch excision with permanent ileostomy. Among the 61 patients who had undergone total or subtotal colectomy, 26 (42.6%) developed early postoperative complications, including 10 (16.4%) Clavien-Dindo Grade III-IV complications and one death (1.6%), the last being attributable to multiorgan dysfunction. Three patients (4.9%) had late complications; the difference in incidence of postoperative complications between the 2014-2019 and 2020-2024 groups is not statistically significant (both P>0.05). Multivariable analysis identified intraoperative blood transfusion (OR: 2.12, 95% CI: 1.19–3.75, P=0.010) and interval to stoma closure > 120 days (OR: 2.05, 95%CI: 1.16-3.62, P = 0.013) as independent risk factors for development of pouchitis in UC patients undergoing TPC-IPAA. Conclusion:Surgical treatment of UC remains safe in the biologics era. Proactive strategies to reduce intraoperative blood transfusion and achieve timely stoma closure may reduce the risk of pouchitis in UC patients undergoing TPC-IPAA.

Objective:To investigate the feasibility and safety of laparoscopic purse- string suture clamps combined with multi-functional seal caps for esophagojejunal Roux-en-Y anastomosis during total laparoscopic radical total gastrectomy (TLTG).Methods:This was a retrospective descriptive study of 42 patients with primary gastric malignancies who underwent TLTG at the First Affiliated Hospital of Nanjing Medical University that utilized laparoscopic purse-string suture clamps and multi-functional seal caps for esophagojejunal anastomosis between May, 2024 and January, 2025. The cohort included 33 males and 9 females, with a mean age of (67.7 ±9.5) years and a mean body mass index (BMI) of (23.9±2.9) kg/m 2. The American Society of Anesthesiologists (ASA) physical status classifications were I - II in 40 patients and III in 2 patients, and all patients were definitively diagnosed preoperatively via gastroscopy, dual-energy CT, and/or MRI. Tumor locations included the gastroesophageal junction (GEJ) in 28 cases (Siewert type II - III), the upper third of the stomach in 12 cases, and the middle third in 2 cases. The median distance of esophageal invasion was 1.3 cm, though in 10 cases this was ≥2 cm. Preoperative TNM staging was I-II in 17 patients and III in 25 patients. Surgical outcomes including operative time, anastomosis time, intraoperative blood loss, pathological results, and postoperative recovery were retrospectively analyzed. Results:All 42 operations were successful. The mean operative time was(212.5±26.4) minutes, and the average time from multi-functional seal cap placement to completion of the esophagojejunal anastomosis was (54.2±7.5) minutes. Mean intraoperative blood loss was (79.9±21.3) ml. Postoperative pathology confirmed R0 resection in all specimens, with a mean proximal esophageal margin distance of (2.1±1.6) cm. Furthermore, (51.9±15.1) lymph nodes on average were harvested from each patient; the mean time to oral intake was (149.5±41.4) hours; and the mean hospital stay was (11.3±5.4) days. Postoperative complications occurred in 6 patients: anastomotic leakage ( n=2), residual intra-abdominal infection ( n=1), pulmonary infection ( n=3), and Clavien-Dindo grade III or higher complications occurred in 2 patients. No recurrence, mortality, or anastomosis-related complications were observed within a median follow-up of 5.8 months (range 3.5-11.2). Conclusion:We find the application of the laparoscopic purse-string suture clamps and multi-functional seal caps for esophagojejunal anastomosis in TLTG to be safe and feasible, with satisfactory short-term outcomes.

Hepatocellular carcinoma （HCC） with biliary duct tumor thrombus （BDTT） is currently not common in clinical practice and is easily misdiagnosed， and previously， it was often considered an advanced stage of the disease with a poor prognosis， making its treatment challenging. However， in-depth studies in recent years have gradually deepened our understanding of this disease， leading to significant changes in diagnostic and treatment concepts. Currently， comprehensive treatment， mainly surgery， is used for treatment， but there is still controversy over the selection of clinical treatment strategies. This article provides a detailed discussion on surgical methods and prognosis， in order to provide a reference for clinical treatment options.

Objective:To construct a nomogram model for predicting the incidence of hepatocellular carcinoma based on serum abnormal prothrombin and alpha-fetoprotein and evaluate the predictive effect.Methods:Retrospective analysis of data from 351 patients with liver disease who received treatment at the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2023, including 285 males and 66 females, aged (52.9±11.9) years. Among the 351 patients, there were 229 cases (65.2%) of hepatocellular carcinoma, 87 cases (24.8%) of liver cirrhosis, and 35 cases (10.0%) of chronic hepatitis B. All patients were randomly divided into a training set ( n=245) and a testing set ( n=106) in a 7∶3 ratio without replacement sampling. The training set was used to construct the model, and the testing set was used to evaluate the model. At the same time, gender, age, disease type, and other indicators were compared between the two sets. The risk factors of hepatocellular carcinoma were analyzed by univariate and multivariate logistic regression based on the training set, and a nomogram was constructed to predict the incidence of hepatocellular carcinoma based on the multivariate results. Receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the predictive performance of nomogram, and decision curve analysis was used to evaluate the clinical applicability of the model. Results:There was no statistically significant difference in age, gender, disease type, etc. between the training and testing sets of patients (all P>0.05). Univariate logistic regression analysis showed that age, abnormal prothrombin logarithm (LnPIVKA-Ⅱ), alpha-fetoprotein logarithm (LnAFP), and diabetes were associated with hepatocellular carcinoma (all P<0.05). Multivariate logistic regression analysis showed that older age ( OR=1.07, 95% CI: 1.03-1.12), higher LnPIVKA-Ⅱ ( OR=2.97, 95% CI: 1.97-4.46), higher LnAFP ( OR=1.43, 95% CI: 1.11-1.84) and diabetes ( OR=5.17, 95% CI: 1.02-26.17) were risk factors for hepatocellular carcinoma (all P<0.05). Based on the above variables, a nomogram model for predicting the incidence of hepatocellular carcinoma was constructed. The area under the ROC curve analysis of the nomogram for predicting the incidence of hepatocellular carcinoma was 0.920 (95% CI: 0.886-0.953) in the training set and 0.934 (95% CI: 0.891-0.977) in the testing set. The calibration curve fit well with the standard curve, and the prediction was basically consistent with the actual situation. The decision curve analysis showed that the net benefit of the model was greater than 0 under most thresholds (0.1-1.0). Conclusion:The nomogram constructed based on age, LnPIVKA-Ⅱ, LnAFP and diabetes can effectively predict the incidence of hepatocellular carcinoma and has clinical applicability.

Objective:To explore the moderating and mediating roles of psychological resilience in the relationship between job satisfaction and depressive symptoms among petrochemical workers.Methods:In April 2022, a cluster sampling method was used to conduct a questionnaire survey among 1087 in-service employees of a petrochemical enterprise in Henan Province. A total of 861 questionnaires were recovered, including 857 valid ones, with an effective rate of 99.54%. Data on job satisfaction, psychological resilience, and depressive symptoms were collected using the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), Job Satisfaction Questionnaire, and Patient Health Questionnaire-9 (PHQ-9). Spearman rank correlation analysis was applied to analyze the relationships among the scores of job satisfaction, psychological resilience, and depressive symptoms. Hierarchical linear regression analysis was used to test the moderating effect of psychological resilience, and the Bootstrap method was employed to verify the mediating effect of psychological resilience.Results:The scores of job satisfaction, psychological resilience, and depressive symptoms among petrochemical workers were 36.00 (31.00, 36.00) points, 36.00 (30.00, 41.00) points, and 7.00 (3.00, 9.00) points. The detection rate of depressive symptoms was 65.7% (563/857). Results of Spearman rank correlation analysis showed that job satisfaction of petrochemical workers was positively correlated with psychological resilience ( rs=0.270, P<0.01) and negatively correlated with depressive symptoms ( rs=-0.386, P<0.01), psychological resilience was negatively correlated with depressive symptoms ( rs=-0.515, P<0.01). Results of hierarchical linear regression analysis indicated that psychological resilience had no moderating effect on the relationship between job satisfaction and depressive symptoms of petrochemical workers ( b=0.001, P>0.05). Results of the mediating effect test showed that psychological resilience played a partial mediating effect in the relationship between job satisfaction and depressive symptoms ( P<0.01), with a mediating effect value of -0.071 (95% CI: -0.125, -0.045), accounting for 20.16% of the total effect. Conclusion:Psychological resilience exerts a partial mediating effect rather than a moderating effect in the relationship between job satisfaction and depressive symptoms among petrochemical workers.

To examine the evolution of surgical techniques and trends in overall inpatient burden for pediatric adenoidectomy in Beijing tertiary hospitals from 2013 to 2022. A retrospective observational study was conducted using the regional health information platform of Beijing. Data from children aged ≤14 years who underwent adenoidectomy between 2013 and 2022 were extracted, including total hospitalization cost, length of stay(LOS), surgical material cost, surgical fee, operative technique, perioperative antimicrobial drugs cost, coagulation factor cost, and blood transfusion cost. The Mann-Kendall trend test was used to assess temporal changes in total hospitalization expenses and the structure of cost components. The results showed that over the 10-year period from 2013 to 2022, a total of 25 989 children underwent adenoidectomy in tertiary hospitals. The proportion of children aged ≤6 years increased from 59.83% to 76.11%, showing a significant upward trend ( Z=2.15, P=0.032). Only one case required surgical hemostasis due to postoperative bleeding. During the ten-year period, the median hospitalization cost for adenoidectomy in tertiary hospitals was ￥12 425.82 (￥11 307.43, ￥14 955.42).Overall hospitalization cost demonstrated a fluctuating downward pattern, decreasing from ￥15 229.73 in 2013 to ￥13 927.52 in 2022, this declining trend was not statistically significant( Z=-0.54, P=0.592). In contrast, the surgical costs showed an upward trend over the decade increasing from ￥1 856.22 in 2013 to ￥3 726.45 in 2022, which was statistically significant ( Z=3.22, P=0.001), while the cost of surgical materials showed no significant increase ( Z=1.79, P=0.074).Concurrently, the average LOS decreased remarkably from 10.56 days in 2013 to 3.26 days in 2022 ( Z=-3.94, P<0.001). The cost of perioperative antimicrobial drugs decreased ( Z=-3.94, P<0.001), while the cost of coagulation factors and blood transfusion remained unchanged ( Z=0.54, P=0.592; Z=0.56, P=0.578). Comparison between 2013-2017 and 2018-2022 showed a significant increase in the use of coblation from 28.9% to 42.5% ( χ2=638.7, P<0.001).Furthermore, in the coblation group, total hospitalization cost decreased by 27.73%, surgical cost increased by 94.98%, surgical material cost decreased by 10.33%, LOS shortened by 56.24%, and antimicrobial drug cost increased by 43.03%. In contrast, the non-coblation group showed a 23.94% increase in total hospitalization cost, a 57.08% increase in surgical procedure cost, a 33.88% increase in material cost, and a 30.14% reduction in LOS and a 26.0% decrease in antimicrobial drugs cost. In conclusion,from 2013 to 2022, total hospitalization cost for pediatric adenoidectomy in Beijing tertiary hospitals remained stable. Compared to non-coblation techniques, coblation was associated with a shorter LOS, lower total costs, a higher proportion of surgical fees, and a decreased proportion of material costs, without a significant increase in overall healthcare costs.
