Objective:To discuss the feasibility and safety of stage I anastomosis and T-tube fistulation in laparoscopic local resection of duodenal tumors.Methods:A descriptive case series study was used to retrospectively analyze the clinical diagnosis and treatment data of 14 patients with duodenal tumors who successfully underwent laparoscopic local resection of duodenal tumors + phase I anastomosis + T-tube ostomy in the Guangdong Provincial Hospital of Chinese Medicine and the First Affiliated Hospital of Guangzhou University of Chinese Medicine from October 2021 to March 2024. The resection and reconstruction steps of laparoscopic local resection of duodenal tumor + phase I anastomosis + T-tube ostomy are as follows: (1) after the safe margin is clear, the duodenal tumor is completely removed in full thickness, and the specimen bag is taken out and sent to frozen section to determine the nature of the tumor and the negative margin; (2) Perforate the anterior duodenal wall below the tumor plane, place a 16# T tube, and fix it with laparoscopic purse string suture. The abdominal wall is led out through the duodenum, and the duodenal T tube fistulation is performed; (3) The duodenum was continuously sutured in a full-thickness transverse shape, and the seromuscular layer was strengthened to form a phase I anastomosis. The nutritional improvement of patients after operation was mainly observed, and the intraoperative situation and postoperative complications were recorded.Results:No conversion to laparotomy, postoperative emergency reoperation, intraoperative and postoperative complications occurred in 14 patients with duodenal tumors who completed laparoscopic local resection of duodenal tumors + phase I anastomosis + T-tube ostomy. The operation time was (225.43 ± 56.54) min, and the intraoperative blood loss was (72.14 ± 74.65) ml. The patient recovered well after operation, and no severe postoperative abdominal bleeding occurred. Postoperative gastrointestinal angiography showed that the anastomotic stoma was unobstructed, and there were no stenosis, anastomotic leakage and other related complications. There was no significant difference in serum albumin [(37.09 ± 3.53) g/L vs. (37.52 ± 4) g/L] and hemoglobin [(100.79 ± 31.93) g/L vs. (103.07 ± 19.6) g/L] between before and 1 week after operation ( P > 0.05). Conclusion:Laparoscopic local resection of duodenal tumor + phase I anastomosis + T-tube fistulation can be used as one of the safe and feasible improved methods for local resection of duodenal tumor to effectively reduce the occurrence of related complications.

Urinary tract infections (UTIs) are infectious diseases caused by uropathogenic bacteria, characterized clinically by high infection and recurrence rates, with uropathogenic Escherichia coli (UPEC) being the main causative agent. This bacterium possesses various virulence factors that enable it to adhere, colonize, invade, and cause disease in the bladder. This article reviews the pathogenic mechanisms of UPEC, focusing on its virulence factors, interactions with the host, and persistence in the body, aiming to expand our understanding of the processes involved in the occurrence and recurrence of UTIs.

Objective:To explore the surgical procedure and clinical efficacy of free chimeric tendon mini-flap pedicled with superficial palmar branch with flexor carpi radialis of radial artery in reconstruction of the dorsal finger composite tissue defects.Methods:From January 2020 to December 2022, 6 fingers (6 patients) with combined dorsal soft tissue and extensor tendon defects were treated in the Department of Plastic and Reconstructive Surgery, the First Affiliated Hospital of Ningbo University. The ipsilateral free chimeric flexor carpi radialis tendon mini-flap pedicled with superficial palmar branch of radial artery was used to reconstruct the soft tissue defects that sized 1.5 cm×1.8 cm - 2.5 cm×3.0 cm and the extensor tendon defects ranged 1.5 - 2.5 cm in length. The flap donor sites were directly sutured. Blood supply and survival of the flaps were observed after surgery. Postoperative follow-ups were scheduled at the 1, 3, 6, 12, 18 and 24 months after surgery and mainly conducted at the outpatient clinic and by home visits. Patients who were inconvenient to visit the hospital were reviewed through WeChat or telephone interviews. The follow-up included the colour, texture, appearance, sensation of the flap and functional status of the affected fingers.Results:After surgery, all 6 flaps survived without any incidence. All flap donor sites achieved stage I healing. The postoperative follow-up lasted 6-22 (mean 11.3) months. The colour and texture of the flaps were similar to those of the skin of dorsal finger, without bulky appearance. For the 3 flaps that had nerve anastomoses, the sensation recovery of the flap achieved to S 3+, with TPD at 7.6 mm, 7.9 mm and 8.3 mm, respectively, and 7.93 mm in average. For the 3 flaps without nerve anastomosis, the sensation recovery of the flap achieved S 3. No complication occurred at the donor sites. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 4 patients were in excellent and 2 in good. Conclusion:Transfer of free chimeric flexor carpi radialis tendon mini-flap pedicled with superficial palmar branch of radial artery in reconstruction of the soft tissue defect in dorsal finger offers the advantages of reliable blood supply, sufficient blood reflux, bridging blood vessels, nerves and tendons, a minimal damage to the donor site and satisfactory postoperative outcome. It is an ideal surgical procedure for reconstruction of the composite tissue defects in dorsal finger.

Objective:To explore the application of anterior esophageal wall full layer fixation and gastric tube guidance in total laparoscopic overlap method for intracorporeal esophagojejunostomy.Methods:Overlap esophagojejunostomy with anterior esophageal wall full layer fixation and gastric tube guidance is suitable for patients with advanced gastric cancer (clinical stage: cT1b~4aN0~3M0) and esophageal invasion <3 cm, who underwent radical total gastrectomy+ overlap esophagojejunostomy. The main operation procedure was performed as follows: A titanium clip was used for fixation of the full anterior wall of esophagus before overlap esophagojejunostomy, and the side‐to‐side esophagojejunostomy was performed with the linear stapler under the guidance of gastric tube. Then the titanium clip was removed after confirming that the correct cavity was entered. Finally, the common outlet was closed by two barbed sutures. A descriptive case series study was conducted. The clinical data of patients who underwent laparoscopic radical gastrectomy and overlap esophagojejunostomy with anterior esophageal wall full layer fixation and gastric tube guidance in Guangdong Provincial Hospital of Chinese medicine and the First Affiliated Hospital of Guangzhou University of Chinese medicine from May 2021 to June 2023 were retrospectively analyzed.Results:A total of 42 patients were collected, and all of them were successfully completed laparoscopic total radical gastrectomy without conversion to laparotomy or perioperative death. The esophagojejunostomy time, operative time, intraoperative blood loss was 17(5‐25) minutes, (258.8±38.0) minutes and 50(20‐200) ml, respectively. The incidence of esophageal false lumen was 0%, and there were no intraoperative complications. The time of gastric tube removal, initial fluid diet intake and the duration of postoperative hospital were 2(1‐5) , 4(1‐8) and 8(4‐21) days, respectively. There were no postoperative anastomotic hemorrhage, anastomotic stenosis and other related complications. One patient (2.38%) developed a Clavien‐Dindo IIIb complication, which was abdominal hemorrhage after operation. The second surgical exploration confirmed that the patient was bleeding due to gastroduodenal artery rupture. After intraoperative suture hemostasis, fluid expansion, blood transfusion and other treatments, the patient was discharged on the 15th day after the operation. Three patients (7.14%) developed Clavien‐Dindo grade II complications, including anastomotic leakage, chylous leakage and pulmonary infection, and were discharged after conservative treatment such as anti‐infection and prolonged retention of drainage tube.Conclusions:Laparoscopic overlap method for intracorporeal esophagojejunostomy with anterior esophageal wall fixation and gastric tube guidance can shorten the time of esophagojejunostomy and prevent the occurrence of false lumen, and do not increase anastomose‐related complications.

Objective:
To understand parents attitudes towards adolescent sexual education in Baoshan City of Yunnan Province, and to explore the correlation between attitudes and their proactive behavior in adolescent sexual education, so as to provide reference for improving parents initiative in adolescent sexual health education.
Methods:
From November to December 2022, a stratified random cluster sampling method was used to select 7 389 parents of students from 35 primary, middle, and high schools in Baoshan City of Yunnan Province for a questionnaire survey on adolescent sexual health education in parents schools. Chi-square tests were conducted to compare the attitudes of parents towards sexual health education among different groups and their proactive behavior in providing sexual health education to their children. A multivariate Logistic regression model was used to analyze the correlation between parents attitudes towards sexual education and proactive sexual health education.
Results:
Totally 43.17% ( 3 190 ) of parents had a more open attitude towards sex education for their children, with parents of girls, parents of elementary school students, mothers, <30 years old, junior high school education, workers, service personnel, married, harmonious relationships with their children and democratic parents had a higher rate of actively providing sex education for their children ( χ 2=4.65, 401.92, 23.53 , 197.50, 38.18, 13.65, 6.54, 8.07, 32.17, 96.58, P <0.05). Parents with a more conservative attitude towards sex education and parents of boys were negatively correlated with parents actively providing adolescent sexual health education to their children ( OR =0.86, 0.38, P <0.05). Parents who were <30, 30-<40, 40-50 years old, individuals/businesses, married, divorced, had a good and decent relationship with their children were positively correlated with their parents proactive adolescent sexual health education for their children ( OR =1.50, 1.90, 1.37, 1.22, 1.60, 1.32, 1.94, 1.53, P <0.05).
Conclusion
A more open attitude towards adolescent sexual health education can serve as a predictive factor for proactive adolescent sexual health education. In order to increase the rate of family sexual health education, it is recommended to enhance parents awareness of their responsibility for their children s sexual health education, promote harmonious parent-child relationships between parents and children, and communicate with their children with an open attitude.
