OBJECTIVE: To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children. METHODS: The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group). There was no significant difference in baseline data such as gender, age, side, cause of injury, Gartland type, Kirschner wire configuration, and time from injury to operation between the two groups ( P>0.05). The closed reduction rate, total operation time, time of medial humeral condyle pin placement, fluoroscopy times during medial pin placement, rate of one-time determination of medial entry point, ulnar nerve injury incidence, and fracture healing time were recorded and compared between the two groups. At the same time, the closed reduction rate of patients with the time from injury to operation ≤24 hours and >24 hours was compared. The elbow function was evaluated by Mayo elbow function score. RESULTS: The closed reduction rate of the study group was significantly higher than that of the control group ( P<0.05). Among all patients, the closed reduction rate of patients with the time from injury to operation ≤24 hours [73.3% (22/30)] was significantly higher than that of patients >24 hours [42.9% (12/28)] ( χ ²=5.545, P=0.019). The total operation time, medial needle placement time, and fluoroscopy times in the study group were significantly less than those in the control group, and the one-time determination rate of medial needle entry point in the study group was significantly higher than that in the control group ( P<0.05). There were 4 cases of ulnar nerve injury in the control group, and no ulnar nerve injury in the study group, but there was no significant difference in the incidence of ulnar nerve injury between the two groups ( P>0.05). All patients were followed up 6-12 months (mean, 8 months). There was no bone nonunion in both groups, and the fracture healing time of the study group was significantly shorter than that of the control group ( P<0.05). Volkmann ischemic contracture, heterotopic ossification, myositis ossificans, and premature epiphyseal closure were not observed after operation. No complications such as loosening or fracture of Kirschner wire occurred. At last follow-up, the Mayo elbow joint function score was used to evaluate function, and there was no significant difference between the two groups ( P>0.05). CONCLUSION In the treatment of extended supracondylar fractures of the humerus in children, the elbow skin fold extension line can help to quickly locate the medial epicondyle of the humerus, quickly insert Kirschner wire, and reduce the operation time and trauma.

Objective:To investigate the efficacy of virtual simulation-guided unilateral locking plate combined with Jail screw technique for double column tibial plateau fractures involving the posterolateral plateau.Methods:A retrospective case series study was conducted to analyze the clinical data of 32 patients with double column tibial plateau fractures involving the posterolateral plateau admitted to Nanjing Drum Tower Hospital Group Suqian Hospital from March 2018 to March 2022, including 20 males and 12 females, aged 37-69 years [(47.5±6.9)years]. According to AO/OTA classification, the fractures were classified as type 41B in 17 patients and type 41C in 15. According to the three-column classification, the fractures were classified as lateral column+posterior column in 17 patients and medial column+posterior column in 15. Virtual simulation technique was used to simulate surgical operation before surgery. After reduction, the patients′ tibial plateau mirror models of the healthy side were used to simulate the implantation of internal fixators on the affected side. The position data of the placed internal fixators were obtained to guide the personalized treatment with unilateral locking plate combined with Jail screw technique. The total number of Jail screws, average number of Jail screws, distribution and accuracy of screw placement, operative duration, intraoperative blood loss, and fracture healing status were recorded. The posterior tibial plateau angle (PTSA), proximal medial tibial angle (MPTA) and Rasmussen anatomical score were compared before operation, at 1, 3, 6, 12 months after operation and at the last follow-up. The Lysholm scores at 6, 12 months after operation and at the last follow-up were used to evaluate the knee function. At the last follow-up, the knee range of motion was measured. Postoperative complications were observed.Results:All the patients were followed up for 28-36 months [(30.7±2.3)months]. The total number of Jail screws inserted was 48, with an average of (1.5±0.5) screws. In the sagittal direction, 1-2 Jail screws were inserted in each patient, with an accuracy rate of 88% (42/48). The operative duration was 78-116 minutes [(98.7±10.5)minutes]. The intraoperative blood loss was 70-120 ml [(96.6±15.6)ml]. All the fractures had healing of stage I, with a healing time of 4-7 months [(5.4±0.9)months]. At 1, 3, 6, 12 months after operation and at last follow-up, the PTSA, MPTA, and Rasmussen anatomical scores were significantly improved when compared with those before operation ( P<0.05), while there was no statistically significant difference between those at various postoperative time points ( P>0.05). The Lysholm knee scores were (83.6±3.9)points, (88.5±3.6)points, and (93.7±2.6)points at 6, 12 months after operation, and at the last follow-up, respectively, which were gradually increased with the passage of the follow-up time ( P<0.05). The range of motion was (121.4±4.6)° in flexion and was 0.0(0.0, 3.0)° in extension at the last follow-up. Two patients had superficial wound infection and 1 had wound dehiscence after operation, which recovered with dressing change or debridement and suturing. No deep infection, vascular injury or nerve damage occurred. Conclusions:The virtual simulation-guided unilateral locking plate combined with Jail screw technique has the advantages of high accuracy of screw placement, shorter operative duration, less intraoperative blood loss, satisfactory fracture reduction, favorable recovery of knee function and range of motion, and fewer postoperative complications in the treatment of double column tibial plateau fractures involving the posterolateral plateau.

Objective:To analyze the clinical characteristics and prognosis of patients with stiff-person syndrome (SPS) associated with glutamic acid decarboxylase (GAD) antibodies.Methods:A retrospective analysis was conducted on demographic characteristics, clinical manifestations, auxiliary examination results, treatment, and prognosis of patients with GAD antibody-related SPS treated at Peking Union Medical College Hospital from January 2015 to July 2023.Results:A total of 33 patients were included, comprising 26 females (78.8%) and 7 males (21.2%), with an onset age of (42±12) years and a disease duration of 24.0 (10.5, 37.5) months. Two cases (6.1%) were diagnosed with tumors, including 1 case with invasive thymoma and 1 case with small cell lung cancer. The majority of patients (87.9%, 29/33) presented with stiffness of trunk and proximal limb muscles, 42.4% (14/33) of patients exhibited episodic spasm, and 54.5% (18/33) of patients were triggered by stimuli such as sound and light. Babinski or Chaddock reflexes were elicited in 33.3% (11/33) of patients. Some patients (36.4%, 16/33) had concurrent limbic encephalitis/epilepsy or cerebellar ataxia (referred to as complex SPS). The median cerebrospinal fluid (CSF) white blood cell count was 2×10 6/L [quartile: 1×10 6/L, 6×10 6/L; range: (0-30)×10 6/L], with mild elevation in 28.0% (7/25) of patients. Multi-channel surface electromyography in 14 out of 21 cases (66.7%) suggested synchronous contraction of agonist and antagonist muscles in a relaxed state. The modified Rankin Scale (mRS) score during the acute phase was 4 (3, 4). All patients received treatment with benzodiazepines or baclofen. Thirty patients (90.9%, 30/33) received first-line immunotherapy, 3 patients (9.1%, 3/33) received second-line immunotherapy with rituximab, and 14 (42.4%, 14/33) received mycophenolate mofetil as long-term immunotherapy. The follow-up period was 16 (10, 42) months, with a median best mRS score of 2; 66.7% (22/33) of patients had a favorable functional prognosis (mRS score≤2), and the recurrence rate was 30.0% (9/30). At the last follow-up, the median mRS score was 2, and 53.3% (16/30) of patients had a favorable functional prognosis. Prognosis was not significantly correlated with gender, age, clinical type, or CSF white blood cell level (all P>0.05). Conclusions:SPS is one of the main clinical phenotypes of GAD antibody-related neuroimmune diseases, commonly observed in middle-aged women, and exhibits a chronic progressive course. Only a minority of patients have concomitant tumors. The diagnosis relies on typical symptoms, GAD antibody testing, and electromyography examination. The initial immune therapy yields good results, but the prognosis for recurrent patients is poor.

Oral ulcers refers to the disruption occurrence of mucosal epithelial integrity,its occurrence and development are affected by a variety of factors such as systemic diseases,genetics,immunity and systemic subhealth state;sleep is closely related to human health,and long-term sleep disturbance can lead to endocrine disorders,immune disorders,and metabolic diseases.Epidemiologic studies find that sleep quality is closely re-lated to mucosal healing,and sleep disorders may be a potential risk factor for impaired mucosal healing.The animal experiments verify that sleep deprivation exacerbates oral ulcer symptoms and delays the oral ulcer healing in rats,but the exact cellular and molecular mechanisms are unclear.This paper reviews the mecha-nisms of sleep disorders in affecting mucous membrane healing after oral ulcer in order to provide a theoretical basis for basic research and treatment of mucosal healing and soft tissue regeneration.

Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.
