Objective: To analyze the epidemiological characteristics and trends of other infectious diarrhea among children under 18 years old in Guangzhou City from 2014 to 2020, and to explore the correlation between climatic factors and the incidence of the disease, so as to provide reference for the early prevention of infectious diseases. Methods: The data of cases of other infectious diarrhea and meteorological data of children under 18 years old in Guangzhou City from 2014 to 2020 were collected through the Chinese Infectious Disease Reporting System and the Guangzhou Meteorological Bureau. The correlation between meteorological factors and the incidence of other infectious diarrhea was analyzed using negative binomial regression. Results: A total of 104 566 cases of other infectious diarrhea among children under 18 years old were reported in Guangzhou City from 2014 to 2020, with a male to female ratio of 1.48∶1. The incidence rate was the highest in 2017 (980.83 per 100 000) and the lowest in 2020 (388.22 per 100 000). The peak of incidence occurred from October to March of the following year. Children under 5 years old accounted for 87.95% of all cases. The number of cases of other infectious diarrhea was negatively correlated with the temperature of the previous 6 days ( IRR = -0.07 ), and positively correlated with the temperature difference on the day of onset ( IRR =0.02) (both P <0.05). It was also positively correlated with the wind speed of the previous 7 days ( IRR=0.07, P <0.05), but there was no statistically significant correlation with the relative humidity on the day of onset ( IRR=-0.00, P >0.05). Conclusions Low temperature, large temperature difference, and high wind speed can increase the risk of other infectious diarrhea. It is necessary to strengthen the prediction and early warning in conjunction with meteorological changes, and warn kindergartens and schools to enhance preventive measures against the clustering of other infectious diarrhea cases.

Pneumothorax during pediatric laparoscopic surgery is a potentially fatal complication that may not be promptly recognized. It can occur due to congenital anatomical abnormalities, pre-existing pulmonary disease, or operative factors during laparoscopy. Clinical presentation may range from asymptomatic to acute respiratory distress, pleuritic chest pain, and even life-threatening circulatory collapse. Here, we report a case of sudden intraoperative pneumothorax accompanied by extensive subcutaneous emphysema of the neck and chest wall during laparoscopic high ligation of the hernial sac in a child. The child presented with a reducible left lower abdominal mass and mild pain 3 days prior but did not seek medical attention. Symptoms worsened 1 day prior to admission, with difficulty reducing the mass. On April 8, 2021, the patient was admitted to the Department of Anesthesiology, Zhuzhou Hospital Affiliated to Xiangya School of Medicine of Central South University, with a diagnosis of "left inguinal hernia." On the second day of hospitalization, laparoscopic high ligation of the left inguinal hernia sac was performed under general anesthesia. During the procedure, the patient developed a sudden increase in airway pressure, marked hemodynamic fluctuations, crepitus in the neck and right anterior chest regions, and significantly diminished breath sounds in the right lung. Emergent bedside chest X-ray confirmed a right-sided pneumothorax. Immediate intervention including thoracic needle decompression, closed thoracic drainage, the lung re-expansion was performed. The patient was discharged on the 7th postoperative day with full recovery. This case highlights the need for clinicians to remain vigilant for iatrogenic pneumothorax during pediatric laparoscopic surgery. Close intraoperative monitoring of vital signs is crucial for early detection, recognition, and timely management of pneumothorax to ensure patient safety during minimally invasive procedures.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective To review the clinical trial registration characteristics of TCM prevention and treatment of stroke;To provide reference for future relevant clinical trials.Methods Clinical trials of TCM prevention and treatment of stroke registered on ChiCTR and NCT from the establishment of the databases to August 31,2023 were retrieved.Excel 2019 was used to remove duplication and extract relevant data.SPSS 27.0 was used to analyze the included data and drown corresponding charts.The characteristics of trails were summarized.Results Totally 540 registered clinical trials were included,among which,449(83.15%)were from ChiCTR and 91(16.85%)were from NCT.The number of registered was is generally increasing year by year.The included research involved 8 countries,of which 29 provinces of China were involved;213 institutions and 391 researchers were involved.The main source of funding was government finance(52.41%);a total of 216 368 participants were included in these trials,with the majority of trials having a sample size of 50-100 cases(32.22%).The main research type was intervention study(88.70%),and the study design was mostly randomized controlled trial(82.59%).Most of the trials(39.63%)did not clearly report the blind method,followed by double blind clinical trail(21.67%)and evaluator blind clinical trial(13.70%).Clinical trials focused on the full cycle of stroke management,including acute,convalescent,sequelae,and stroke prevention.Among them,the study of sequelae stage of stroke accounted for the largest proportion(62.04%),which specifically covered motor dysfunction,cognitive mental dysfunction,swallowing disorders,etc.The main intervention measures were acupuncture(42.41%),followed by Chinese patent medicine(21.12%)and tuina(10.37%).The main outcome evaluation indexes were motor function evaluation(17.10%)and nerve function evaluation(14.56%).Conclusion The clinical research on the TCM prevention and treatment of stroke is in a period of rapid growth with increasing attention and deepening of the research,which is conducive to improving the prognosis of patients.However,there are still some problems,such as studies with weak systematicness,unreasonable proportion structure of intervention measures,and strong subjectivity of outcome evaluation indicators.

Objective:To evaluate the clinical efficacy of endoscopic treatment of superficial non-ampullary duodenal adenoma.Methods:A retrospective analysis was performed on the clinical data and follow-up information of patients diagnosed with superficial duodenal non-ampullary adenomas via preoperative endoscopy and treated endoscopically at Peking University First Hospital between January 2013 and January 2024. The overall en bloc resection rate, complete resection rate of the lesion, perioperative complications, and recurrence rates were evaluated. Patients were categorized into three groups based on their treatment modality: endoscopic mucosal resection (EMR)（ n=46）, endoscopic submucosal dissection (ESD)（ n=16）, and modified ESD (ESD with snare, ESD-S)（ n=24）. Comparative analyses were conducted to evaluate operative time, en bloc resection rate, and complete resection rate among the three groups. Results:Among 86 patients, the overall en bloc and complete resection rates were 87.2% (75/86) and 86.0% (74/86), respectively. No case of delayed bleeding was observed during the perioperative period. Intraoperative perforation occurred in two patients, both of whom improved following conservative management. Delayed perforation was noted in four patients, and three of them were successfully managed with surgical intervention, while one case was resolved after conservative treatment. During the follow-up period, local recurrence was identified in two patients. Following re-treatment with endoscopy and continuous surveillance, no further recurrence was observed. The operative times for the EMR group, ESD-S group, and ESD group were 4 (1-36) minutes, 25 (5-190) minutes, and 46 (5-150) minutes, respectively. Significant differences were observed in operative times among the three groups ( Hc=49.892, P<0.001). The en bloc resection rates for the EMR, ESD-S, and ESD groups were 80.4% (37/46), 91.7% (22/24), and 100.0% (16/16), respectively. The complete resection rates were 80.4% (37/46), 91.7% (22/24), and 93.8% (15/16) for the respective groups. Conclusion:Endoscopic treatment demonstrates favorable efficacy and safety for superficial non-ampullary duodenal adenoma. In addition to traditional EMR and ESD, ESD-S is also an effective procedure for endoscopic treatment of non-ampullary duodenal adenoma.

Objective To explore the application value of improving the operation method of the coaxial microcatheter system to increase the recanalization rate of long-segment occluded blood vessels in the lower extremity arteries.Methods Eleven patients with long-segment occlusion of the lower extremity arteries were selected.Firstly,the angiographic catheter was sent to about 3-4 cm proximal to the occluded segment to provide support and direction control of the coaxial microcatheter system.Then,the microcathe-ter was sent to about 1 cm proximal to the occluded segment through the angiographic catheter,and the microguide wire was sent to the occluded segment,making the tip of the guide wire closely adhere to the occluded segment.The guide wire was fixed by using the guide wire controller to ensure that the guide wire in the blood vessel was always about 1 cm exposed outside the microcatheter.Meanwhile,the microcatheter and the microguide wire were rotated to make the tip form a"spring"shape similar to that of a pipe-line dredging machine,so that the coaxial microcatheter system could pass through the occluded segment of the blood vessel in this shape.After confirmed that the microcatheter had entered the lumen of the distal outflow tract blood vessel,the subsequent interven-tional treatment was completed according to the conventional method.Results Eleven patients with long-segment occluded blood vessels in the lower extremity arteries were successfully treated with improving the operation method of the coaxial microcatheter system to dredge the occluded segment,and completed the interventional treatment of the affected limb blood vessels without vascu-lar rupture,vascular bleeding or arterial dissection.Conclusion Using the improved operation method of the coaxial microcatheter system to dredge the long-segment occluded blood vessels of the lower extremity arteries is simple,safe and has a high success rate,which is worthy of clinical promotion.

Objective:To evaluate the feasibility and preventive efficacy of a fascia- locking circular continuous suture ostomy technique in reducing parastomal hernia incidence.Methods:This technique was applied to patients undergoing permanent colostomy following radical rectal cancer resection. Surgical steps included: (1) A circular incision was made 1-2 cm medial to the intersection of the lateral margin of the rectus abdominis muscle and the line connecting the umbilicus to the left anterior superior iliac spine. Subcutaneous tissues were dissected vertically to expose the anterior rectus sheath, followed by blunt separation of the rectus abdominis after longitudinal incision of the sheath. The posterior rectus sheath and peritoneum were similarly incised. (2) Eight equidistant interrupted sutures (anchoring knots) were placed through the anterior rectus sheath, partial rectus abdominis, posterior rectus sheath, and peritoneum. (3) The terminal colon was exteriorized, and continuous sutures were applied to secure the anchoring knots and seromuscular layers of the bowel between knots, forming a circular locking mechanism by tying the terminal suture to the initial knot's tail. (3) The skin and seromuscular layers of the bowel margin were intermittently sutured (8-12 stitches) to achieve mucosal eversion.Results:From February to October 2023, 13 patients (11 males, 2 females; age: 67 ± 10 years; BMI: 23.8 ± 4.0 kg/m2) underwent this technique at the Second Affiliated Hospital of Army Medical University. Mean stoma creation time was 15.7 ± 3.0 minutes. During a follow-up of 14.6 ± 3.1 months, physical examinations and abdominal CT scans identified parastomal hernias in 2 male patients at 10 and 7 months postoperatively. Only one patient experienced a Clavien-Dindo grade ≥Ⅲ complication, which resolved with treatment. No stoma-related complications (e.g., infection, stenosis, or prolapse) occurred in any patient.Conclusion:The fascia-locking circular continuous suture ostomy technique is safe and feasible, demonstrating potential efficacy in preventing parastomal hernia following colostomy.
