OBJECTIVE To evaluate the efficacy and safety of amoxicillin combined with proton pump inhibitor （PPI） or potassium-competitive acid blocker （P-CAB） for Helicobacter pylori （Hp） eradication. METHODS Randomized controlled trial （RCTs） on amoxicillin combined with PPI or P-CAB for Hp eradication were retrieved from PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， and VIP data. The search time frame was from database inception to September 5， 2025. After literature screening， data extraction， and quality assessment， a network meta-analysis was performed using Stata 17.0 software. RESULTS A total of 12 RCTs involving 5 515 patients were included， encompassing 8 therapeutic regimens： PPI combined with high-dose amoxicillin for 14 days （TR1）， PPI combined with low-dose amoxicillin for 14 days （TR2）， P-CAB combined with high-dose amoxicillin for 7 days （TR3）， P-CAB combined with high-dose amoxicillin for 14 days （TR4）， P-CAB combined with high-dose amoxicillin for 10 days （TR5）， P-CAB combined with low-dose amoxicillin for 7 days （TR6）， P-CAB combined with low-dose amoxicillin for 14 days （TR7）， and P-CAB combined with low-dose amoxicillin for 10 days （TR8）. The network meta-analysis results showed that， in terms of intention-to-treat Hp eradication rates， the eradication rates of TR5 and TR4 were significantly higher than those of TR3， TR8， TR6 and TR1 （ P ＜0.05）. The surface under the cumulative ranking curve （SUCRA） values from highest to lowest were： TR4 （89.7%）＞TR5 （82.3%）＞TR7 （71.5%）＞ TR2 （48.6%）＞TR1 （43.9%）＞TR8 （28.7%）＞TR3 （22.7%）＞TR6 （12.6%）. Regarding safety， the incidence of adverse reactions in TR3 and TR5 was significantly lower than that in TR1 （ P ＜0.05）. The SUCRA values from highest to lowest were： TR1 （91.3%）＞TR4 （79.8%）＞TR5 （55.0%）＞TR7 （50.9%）＞TR8 （41.3%）＞TR2 （36.4%）＞TR3 （27.6%） ＞TR6 （17.7%）. CONCLUSIONS Although the regimen of P-CAB combined with high-dose amoxicillin for 14 days demonstrates the best efficacy， the combination of P-CAB with high-dose amoxicillin for 10 days exhibits a better balanced profile in terms of both efficacy and safety.

This study analyzes the disease burden of Attention-Deficit Hyperactivity Disorder (ADHD) in children and adolescents in China and globally from 1990 to 2021, providing data support and strategic recommendations for public health policy and disease intervention.

In the context of continuously deepening medical and health system reforms and comprehensively promoting the "Healthy China" strategy, Henan Provincial People's Hospital has established a regional collaborative and vertically integrated critical care service structure and network. This initiative aims to enhance information empowerment, strengthen regional collaboration, improve the insufficient primary medical services, and ensure timely and effective treatment for critically ill patients. By establishing a comprehensive dispatch service platform for regional collaborative critical care, building a "top-down" remote medical collaboration network, and forming a cross-regional specialty alliance for critical care, the hospital has improved the efficiency of medical services and enhanced regional capabilities for treating critically ill patients. Simultaneously, for critically serious patients and those with complex diseases at primary medical institutions, a one-stop consultation and referral service has been implemented. This service adopts a "three specialists" approach and a multidisciplinary consultation mechanism within the hospital, constructs a multi-dimensional critical care transfer mode integrating air, ground, and the internet, creates a regional collaborative rescue mode, and implements full-cycle treatment for critically serious patients. The comprehensive, flexible, and efficient service pathway for regional collaborative critical care established by this system ensures timely and safe treatment for critically ill patients, promotes the distribution of high-quality medical resources, and effectively addresses issues such as uneven distribution of high-quality medical resources and varying levels of critical care capabilities. It has facilitated the formation of a new tiered diagnosis and treatment order characterized by "first diagnosis at the primary level, two-way referral, separate treatment for acute and chronic diseases, and vertical integration". This approach has enhanced the diagnostic and comprehensive service capabilities of primary medical institutions. Currently, by strengthening information empowerment and sharing, creating a full-process critical care diagnosis and treatment model, providing medical assistance and cultivating primary-level critical care talent, and promoting appropriate technologies, the hospital has gradually overcome challenges such as barriers to information exchange and sharing between hospitals, overloaded critical care teams, high pressure on patient reception and transfer, and limited critical care capabilities at primary medical institutions. This article summarizes the construction and practical application of this regionally coordinated critical care system, aiming to provide a reference for the management of critical care treatment.

Objective:To investigate the application value of robotic-assisted surgery for pancreatic cancer after neoadjuvant chemotherapy (NAT).Methods:The retrospective and descrip-tive study was conducted. The clinicopathological data of 10 pancreatic cancer patients who underwent robotic-assisted surgery after NAT at The First Affiliated Hospital of Sun Yat-sen University from November 2021 to January 2025 were collected. There were 7 male and 3 female, aged (62±7)years. Observation indicators: (1) NAT conditions; (2) intraoperative conditions; (3) postoperative condi-tions; (4) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. The Kaplan-Meier method was used to calculate survival time. Results:(1) NAT conditions. Of the 10 patients, 4 cases had tumor surrounding the portal vein or superior mesenteric vein more than 180° (no invasion of superior mesenteric artery), 3 cases had concomitant hepatic oligometastasis, and 3 cases had tumor invasion of adjacent organ (2 cases with tumor invasion of left kidney, 1 case with tumor invasion of duodenum). Nine of the 10 patients received chemotherapy of gemcitabine+albumin-paclitaxel, and the other 1 patient received chemo-therapy of fluorouracil + irinotecan + oxaliplatin. After treatment, 3 patients were evaluated as partial remission and 7 patients were evaluated as stable disease. (2) Intraoperative conditions. Of the 10 patients, 5 cases received robotic-assisted pancreatoduodenectomy and 5 cases received robotic-assisted radical antegrade modular pancreatosplenectomy, with no case converted to open surgery. There were 3 cases receiving combined vascular resection and reconstruction, including 2 cases with portal vein resection plus side wall repairing and 1 case with superior mesenteric vein resection plus end to end anastomosis. There were 2 cases receiving combined other organ resection intra-operatively, including 1 case with local hepatectomy and 1 case with left nephrectomy. The operation time of 10 patients was 465(range, 195?565)minutes, volume of intraoperative blood loss was 70(range, 20?350)mL. One case with preoperative anemia required red blood cell transfusion during the operation, while the other cases did not receive any transfusion during the operation. All 10 patients achieved R 0 resection and the number of lymph node dissected was 12±8. Three patients who underwent combined vascular resection and reconstruction had negative margin of the portal vein or superior mesenteric vein. (3) Postoperative conditions. Duration of postoperative hospital stay of 10 patients was (15±8)days, and 1 case developed major complications in grade Ⅲa of Clavein-Dindo classfication. Of the 10 patients, 1 case developed grade B pancreatic fistula, 1 case experienced delayed gastric emptying, and no case had postoperative biliary fistula, chyle leakage, abdominal or anastomotic bleeding, no case underwent reoperation, no case died within postoperative 30 days. (4) Follow-up. All 10 patients were followed up after surgery for 10.0(range, 2.7?40.4)months. All 10 patients underwent postoperative adjuvant chemotherapy, and the time from surgery to the start of adjuvant chemotherapy was (40±12)days. The median overall survival time of 10 patients was 30.4 months, and the median recurrence-free survival time was 10.9 months. Conclusion:Robotic-assisted surgery can be used for pancreatic cancer after neoadjuvant chemotherapy.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the short-term outcomes of robot-assisted pancreato-duodenectomy (RPD) performed by one single surgeon.Methods:The retrospective and descriptive study was conducted. The clinico-pathological data of 240 patients who were performed RPD by one single surgeon at The First Affiliated Hospital of Sun Yat-sen University from July 2016 to October 2023 were collected. There were 130 males and 110 females, aged 59(19)years. All RPD were performed by the same surgeon. Observation indicators: (1) surgical situations; (2) postoperative pathological examination and outcome of patients. Measurement data with normal distribution were expressed as Mean± SD, and measurement data with skewed distribution were expressed as M(IQR). Count data were expressed as absolute numbers or percentages. Results:(1) Surgical situations. Of 240 patients, 15 cases underwent combined vascular resection and reconstruction, and 13 patients were combined with other operations simultaneously. Of 240 patients, 4 cases converted to open surgery, with the conversion rate as 1.67%. The operation time of 240 patients was 458(152)minutes, volume of intraopera-tive blood loss was 50(50)mL, intraoperative erythrocyte transfusion was required in 17 patients. The R 0 resection rate was 99.17%(238/240), the number of lymph nodes harvested was 10(6) and duration of postoperative hospital stay was 17(12)days. (2) Postoperative pathological examination and outcome of patients. Of 240 patients, 51 cases were pancreatic ductal adenocarcinoma, 41 cases were ampullary carcinoma, 41 cases were neuroendocrine neoplasms, 35 cases were pancreatic cystic neoplasms, 28 cases were duodenal carcinoma and 44 cases were other pathologic types. Of 99 patients with major complications, there were 57 cases with clinically relevant postoperative pancreatic fistula, 44 cases with postoperative delayed gastric empty, 11 cases with postoperative biliary fistula, 8 cases with postoperative chyle fistula, 14 cases with incision infec-tion, and 24 cases with postoperative hemorrhage. Multiple complications might occur to the same patient. Reoperation was performed in 6 of the 240 patients. One patient died within 30 days after surgery. Twenty-four patients returned to hospital within 30 days after discharge. Conclusions:RPD performed by one single surgeon is safe and feasible, with favorable short-term outcomes, which can be performed in medical centers with experiences in robot-assisted pancreatic surgery.

OBJECTIVE: To investigate the prevalence of vitamin D deficiency and its association with blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease (COPD). METHODS: We analyzed the data of a total 6163 healthy individuals undergoing routine physical examination in our hospital between October, 2017 and December, 2021, who were divided according to their serum 25(OH)D level into severe vitamin D deficiency group (< 10 ng/mL), deficiency group (< 20 ng/mL), insufficient group (< 30 ng/mL) and normal group (≥30 ng/mL). We also retrospectively collected the data of 67 COPD patients admitted in our department from April and June, 2021, with 67 healthy individuals undergoing physical examination in the same period as the control group. Routine blood test results, body mass index (BMI) and other parameters were obtained from all the subjects, and logistic regression models were used to investigate the association between 25(OH)D levels and eosinophil count. RESULTS: The overall abnormal rate of 25(OH)D level (< 30 ng/mL) in the healthy individuals was 85.31%, and the rate was significantly higher in women (89.29%) than in men. Serum 25(OH)D levels in June, July, and August were significantly higher than those in December, January, and February. In the healthy individuals, blood eosinophil counts were the lowest in severe 25(OH)D deficiency group, followed by the deficiency group and insufficient group, and were the highest in the normal group (P < 0.05). Multivariable regression analysis showed that an older age, a higher BMI, and elevated vitamin D levels were all risk factors for elevated blood eosinophils in the healthy individuals. The patients with COPD had lower serum 25(OH)D levels than the healthy individuals (19.66±7.87 vs 26.39±9.28 ng/mL) and a significantly higher abnormal rate of serum 25(OH)D (91% vs 71%; P < 0.05). A reduced serum 25(OH)D level was a risk factor for COPD. Blood eosinophils, sex and BMI were not significantly correlated with serum 25(OH)D level in patients with COPD. CONCLUSION Vitamin D deficiency is common in both healthy individuals and COPD patients, and the correlations of vitamin D level with sex, BMI and blood eosinophils differ obviously between healthy individuals and COPD patients.

Against tumor-dependent metabolic vulnerability is an attractive strategy for tumor-targeted therapy.However,metabolic inhibitors are limited by the drug resistance of cancerous cells due to their metabolic plasticity and heterogeneity.Herein,choline metabolism was discovered by spatially resolved metab-olomics analysis as metabolic vulnerability which is highly active in different cancer types,and a choline-modified strategy for small molecule-drug conjugates(SMDCs)design was developed to fool tumor cells into indiscriminately taking in choline-modified chemotherapy drugs for targeted cancer therapy,instead of directly inhibiting choline metabolism.As a proof-of-concept,choline-modified SMDCs were designed,screened,and investigated for their druggability in vitro and in vivo.This strategy improved tumor targeting,preserved tumor inhibition and reduced toxicity of paclitaxel,through targeted drug delivery to tumor by highly expressed choline transporters,and site-specific release by carboxylesterase.This study expands the strategy of targeting metabolic vulnerability and provides new ideas of devel-oping SMDCs for precise cancer therapy.
