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.

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 clinical effect of progressive transfer of penile flap combined with local scrotal flap in correction of severe concealed penis in children.Methods:The clinical data of children with severe concealed penis admitted to the Children’s Hospital Affiliated to Zhengzhou University from July 2021 to July 2023 were retrospectively analyzed. The concealed penis was corrected by progressive transfer of penile flap combined with local scrotal flap. During the operation, a small amount of excess inner prepuce was removed and the outer prepuce was cut in the middle of the dorsal side of the penis. Then the penile flap was transferred from dorsal to ventral, gradually covering the wound without tension. The local scrotal flap was lifted upwards and sutured to the frenulum for covering the ventral foreskin defect of the penis. The amount of blood loss during the operation was recorded. The pain tolerance, the duration of prepuce edema, the length of penis extension and the healing of skin flap were observed. The appearance of the penis was followed up to observe whether the penis was retracted, and the satisfaction of the children and their guardians was recorded.Results:A total of 32 male children were enrolled, ranging in age from 3 to 10 years, with an average age of 7.2 years. The penis of all the children had a conical appearance, and the penile shaft was buried under the subcutaneous anterior pubis, which was difficult to palpate in its natural state. The average intraoperative blood loss was about 5 ml. All patients had pain after the operation. Two patients needed a pump to relieve pain, and the rest could tolerate it after rectum administration of indomethacin suppositories. The edema of the prepuce was mild after the operation, and the edema basically disappeared when the patient was discharged 7-9 days later. The penis could be lengthened by 1.5-3.0 cm under static conditions, averaging about 2.0 cm. After surgery, only 1 patient had a small area (about 5 mm × 4 mm) of infection in the scrotal flap and poor incision healing, and scar healing after dressing change and intensive nursing. The other flaps healed well. After 6 to 12 months of follow-up, the penis length of 2 cases was slightly retracted from the time of discharge, and the remaining 30 cases had no significant change. The patients and their guardians were satisfied with the operation results.Conclusion:The progressive transfer of penile flap combined with local scrotal flap correction of severe concealed penis in children can fully lengthen the penile body, and the degree of postoperative retraction is low, the appearance of the penis is good, and the patient satisfaction is high.

Objective To evaluate the mediating effect of lifestyles on the association between family history and cardiovascular disease (CVD). Methods This study was based on the "Early Screening and Comprehensive Intervention of High-risk Populations of Cardiovascular Disease Project". The data were collected from 6 project sites in Hubei Province. Logistic regression analysis was used to investigate the impact of family history and lifestyle on CVD, and the relationship between family history and lifestyle. Mediation analysis was used to evaluate the mediating effect of lifestyle on the association between family history and CVD. Results A total of 5 871 subjects were included in the study from 2015 to 2016, of whom 500 (8.52%) developed CVD and 484 had family history of CVD. The risk of developing CVD was significantly increased in participants with family history of disease (OR = 1.458, P = 0.014) and in those with high level of physical activity (OR = 1.081, P = 0.026). The increase of leisure physical activity time showed a protective effect on developing CVD (OR = 0.977, P < 0.001). Participants with family history significantly increased leisure physical activity (OR = 2.085, P < 0.001), and were less likely to choose occupations with high levels of physical activity (OR = 0.524, P < 0.001). The results of mediation analysis showed that leisure physical activity and occupational physical activity mediated the relationship between family history and CVD, and the β value of the mediating effects were -0.004 (P = 0.010) and 0.002 (P = 0.045), respectively. The β value of the direct effect of family history on CVD was 0.033 (P < 0.05). Conclusion Leisure physical activity and occupational physical activity might mediate the relationship between family history and CVD. People with family history would reduce the risk of developing CVD by increasing leisure physical activity time and choosing occupations with low levels of physical activity.

Objective:To summarize the clinical effect of laparoscopic medial umbilical ligament dissection in two-stage Fowler-Stephens orchiopexy (FSO).Methods:A case-series study was conducted.Clinical data of children who underwent two-stage FSO from March 2020 to July 2022 in the Department of Urology, Children′s Hospital Affiliated to Zhengzhou University were retrospectively analyzed.Indexes such as operation time, amount of blood loss, degree of postoperative pain in the operative area, testicular position, size, texture and parental satisfaction at the operative side 1 month, 6 months and 1 year after surgery were collected.Measurement data of normal distribution were expressed as Mean± SD and compared using the independent sample and paired sample t-tests. Results:A total of 18 children with complete clinical data were included in this study.Their age ranged from 7 months to 10 years, with an average of 2 years.There were 10 cases of FSO on the left side and 8 cases on the right side.Twelve cases (group A) had the testis directly descending to the scrotum without amputation of the umbilical medial ligament during the operation, including 7 cases on the left side and 5 cases on the right side; 6 cases (group B) with testis not descending to the scrotum received amputation of the umbilical medial ligament, and the testicle was pulled into the scrotum without tension, including 3 cases on the left side and 3 cases on the right side.The age of patients in group A [(0.88±0.26) years] was lower than that in group B [(4.32±2.96) years] ( t=-4.11, P<0.05).The operation time of patients in group B was (47.50±1.87) min, slightly longer than that in group A [(46.17±1.47) min] ( t=-1.66, P>0.05).The intraoperative bleeding volume in group B was (5.18±0.42) mL, slightly higher than that in group A [(4.96±0.20) mL] ( t=-1.56, P>0.05).Patients in both groups had mild pain in the operative area, which could be tolerated by the children.There were no significant differences in testicular position, size, texture and satisfaction between the two groups 1 month after surgery.Reexamination at 6 months after operation showed that 1 case in group A had mild testicular retraction, located above the scrotum; no significant testicular retraction was observed in group B; the size and texture of testis in both groups had no significant change compared with those before operation, and the blood supply was normal according to the color ultrasound findings; parental satisfaction was high.Reexamination at 1 year after operation showed that 1 case of testis in group A was located above the scrotum, 2 cases had no obvious development, and the rest cases had increased testis size [(0.51±0.03) mL] compared with before operation [(0.31±0.02) mL] ( t=-22.97, P<0.05); all cases of testis in group B returned to normal position, 1 case had no obvious development, and the rest cases had increased testis size [(0.45±0.02) mL] compared with before operation [(0.24±0.01) mL] ( t=-32.87, P<0.05).There was no significant difference in testicular size increase between group A [(0.20±0.03) mL] and group B [(0.20±0.01) mL] ( t=-1.19, P>0.05). Conclusions:In the case that the medial umbilical ligament obviously affects the testicular descent, it can be dissected, which significantly shortens the distance of testis descending to the scrotum.The testicular position after surgery is normal, and the two-stage FSO does not affect the testicular development.

[Objective] To summarize various treatment methods and experiences of bladder and urethral foreign bodies in children. [Methods] A total of 15 children with bladder and urethral foreign bodies admitted to our hospital during Aug.2015 and Feb.2024 were selected.The characteristics, clinical manifestations, surgical methods, surgical skills and postoperative recovery were analyzed. [Results] The patients aged 7-13 (11.0±1.6) years, including 14 males and 1 female.Preoperative diagnosis was confirmed with color Doppler ultrasound and abdominal standing plain film.Emergency surgery was performed in 14 cases, and open surgery in 1 case with concurrent pyuria, whose foreign bodies were removed after 2 days of anti-infection treatment.Among the 15 children, 9 had foreign bodies removed through cystoscopy, 2 through cystoscopy combined with percutaneous renal puncture kit, 2 through cystoscopy combined with a small incision on the pubic bone, 1 through cystoscopy combined with a scrotal incision, and 1 through cystoscopy combined with a perineal incision.The average surgical time was (63.3±50.5) min, blood loss (1.9±1.9) mL, and postoperative hospitalization (5.8±3.8) days.No complications such as urinary extravasation, urinary fistula, bladder diverticulum, or urinary disorders occurred.Postoperative follow-up of 1 and 3 months showed no complications such as abnormal urination or urinary tract infections. [Conclusion] The onset of bladder and urethra foreign bodies in children is concealed.Once the diagnosis is confirmed, surgery should be performed as soon as possible.The surgical method should be selected based on the comprehensive evaluation of the location, size, shape, and number of foreign bodies and presence of calculi.Minimally invasive surgery can be performed in most cases.
