Objective:To summarize the clinical features of children with anomalous origin of coronary artery (AOCA) who received extracorporeal membrane oxygenation (ECMO) support.Methods:A case series study was conducted. Clinical data was collected from 6 children who were diagnosed with AOCA by coronary computed tomography angiography or digital subtraction angiography and received ECMO support in the Pediatric Intensive Care Unit of Henan Provincial People′s Hospital between January 2020 and August 2024. Descriptive analysis was performed on their clinical features, laboratory test results, point-of-care echocardiography results, imaging findings, surgical management, and outcomes.Results:Among the 6 children (3 males and 3 females), the age of onset was 12.5 (11.0, 13.0) years. All 6 patients were transported from other hospitals under ECMO support. Five patients were admitted with chief complaints of "cardiac arrest after strenuous activity, syncope after strenuous activity, or heart failure" and were initially diagnosed with fulminant myocarditis or cardiomyopathy. All 6 children had significantly elevated troponin and B-type natriuretic peptide levels upon admission. Point-of-care echocardiography revealed segmental left ventricular systolic dysfunction in all 6 children, and AOCA was detected in 2 cases based on bedside ultrasound. ECMO was successfully weaned in 5 children. All 6 cases were diagnosed with AOCA. Four children underwent surgical coronary artery correction, one received a heart transplantation, and one missed the optimal window for surgical correction. Heart transplantation was recommended for the latter, but the parents declined, and the patient was discharged. During the follow-up until August 2025, all 6 children survived.Conclusions:AOCA in children is prone to misdiagnosis as other diseases in the early stage. Timely ECMO support provides the possibility of surgery or heart transplantation for children experiencing acute ischemic and hypoxic episodes due to AOCA, improving survival rates.

ObjectiveTo investigate the efficacy and safety of Shuganning injection in the treatment of liver injury by observing the clinical outcome of patients with liver injury after treatment with Shuganning injection and comparing it with reduced glutathione （GSH）. MethodsThis study was conducted among 175 patients with liver injury who attended 6 hospitals in China （Beijing YouAn Hospital， Capital Medical University； Nanyang First People’s Hospital； The Second Affiliated Hospital of Xi’an Jiaotong University； The Fifth Medical Center of Chinese PLA General Hospital； The Third Hospital of Hebei Medical University； The Affiliated Hospital of Guizhou Medical University） from April 25， 2019 to February 28， 2022. The patients were divided into experimental group （89 patients treated with Shuganning injection） and control group （86 patients treated with GSH）， and the course of treatment was 4 weeks for both groups. Related indicators were recorded before treatment， after treatment， and after drug withdrawal for 8 weeks， including liver function parameters， blood biochemical parameters， blood lipids， coagulation profiles， liver fibrosis markers， traditional Chinese medicine （TCM） syndrome score， and ultrasound findings， as well as adverse events during treatment. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The Wilcoxon signed-rank test was used for comparison of observation indicators before treatment， at week 4 of treatment， and after drug withdrawal for 8 weeks. When the efficacy evaluation of TCM syndromes was used as the outcome， a pooled analysis was performed for the effective cases and the markedly effective cases， and a Logistic regression model was used to calculate the odds ratio （OR） and its 95%CI. ResultsAfter 4 weeks of treatment with Shuganning injection， the patients showed significant reductions in TCM syndrome score （P<0.001） and the levels of aspartate aminotransferase， alanine aminotransferase， total bilirubin， and direct bilirubin （all P<0.001） and a significant increase in the level of albumin （P=0.002）， and these significant improvements persisted after drug withdrawal for 8 weeks. Furthermore， compared with the control group， the experimental group had a significantly higher proportion of patients assessed as effective or markedly effective cases （48.31% vs 32.56%， P=0.033）. Compared with the control group， the experimental group had a significantly greater change in TCM syndrome score at weeks 1-4 of treatment and after drug withdrawal for 8 weeks （P<0.05）. At week 4 of treatment， the experimental group had a significantly greater reduction in alanine aminotransferase than the control group （P<0.05）， and at week 8 after drug withdrawal， the experimental group had a significantly greater reduction in alanine aminotransferase and aspartate aminotransferase than the control group （all P<0.05）. One patient in the experimental group （1.12%） experienced an adverse event， which was determined to be associated with the progression of viral hepatitis. ConclusionShuganning injection can effectively improve liver injury， with good long-term efficacy and a low incidence rate of adverse reactions.

Objective:To investigate the changes in sympathetic nerve activity after lower limb immobilization and the role of sympathetic nerve in regulating disuse atrophy of skeletal muscles.Methods:The experiment was divided into the following 3 parts: ① Twelve 8-week-old male C57 mice were randomly divided into a blank control group and a hind limb fixation group ( n=6). The blank control group received no intervention while the hind limb fixation group received splint fixation of the hind limbs for 2 weeks before the musculoskeletal multi-dimensional characterization was completed at the behavioral, pathological and molecular levels. ② Thirty-six 8-week-old male C57 mice were selected and randomly divided into a control group and 5 hind limb fixation groups (for 1, 3, 5, 7 and 14 days) ( n=6). The control group was fed normally until 14 days without any intervention while the 5 hind limb fixation groups were sampled after fixation for 1, 3, 5, 7 and 14 days, respectively. The level of norepinephrine in the serum and the expression level of tyrosine hydroxylase (TH), a marker of sympathetic nerve activity in the paraventricular nucleus of hypothalamus (PVN), were detected to observe the plasticity of sympathetic nerve activity. ③ Eighteen 8-week-old male C57 mice were selected and randomly divided into a blank control group, a hind limb fixation group and a hind limb fixation plus medication group ( n=6). The blank control group received no intervention while the 2 fixation groups were injected with phosphate buffer (PBS) and propranolol hydrochloride solution for 2 consecutive weeks, respectively. The parameters related to the skeletal muscles were compared between the 3 groups. Results:① Compared with the control group, the mass and function of skeletal muscles in the hind limb fixation group were statistically significantly decreased ( P<0.05). ② The levels of serum norepinephrine [(3.27±1.03) ng/mL, (9.21±1.05) ng/mL, (6.36±0.88) ng/mL, (3.84±1.00) ng/mL, and (3.91±0.75) ng/mL] and the PVN TH levels (42.00%±5.38%, 61.67%±5.57%, 55.82%±3.11%, 50.90%±2.53%, and 39.17%±9.07%) in the 5 hind limb fixation groups (for 1, 3, 5, 7 and 14 days) were significantly higher than those in the control group [(1.81±0.72)] ng/mL and 23.33%±5.50%] ( P<0.05). ③ The wet weight of the gastrocnemius muscle [(93.50±4.32) mg] and the cross-section area of the tibial anterior muscle [(1,180.00±95.09) μm 2] in the hind limb fixation plus medication group were increased significantly compared with those in the hind limb fixation group [(80.83±9.99) mg and (907.80±121.00) μm 2] ( P<0.05). Conclusions:Overactivation of the sympathetic nervous system occurs in the mice model of skeletal muscle disuse atrophy after hind limb fixation. Inhibition of sympathetic nerve activity may reduce the severity of skeletal muscle atrophy at the lower limbs.

Objective:To observe the clinical effect of free superficial temporal fascia flap combined with split thickness skin transplantation in repairing refractory wounds in the anterior tibia.Methods:Data on 19 patients with soft tissue defects in the anterior tibial region who were admitted to the First Affiliated Hospital of Air Force Medical University from September 2019 to October 2023 and met the inclusion criteria were collected and summarized. Among them, 11 were males and 8 were females, aged 19-70 years old. The wound area was 4.3 cm×5.0 cm-6.8 cm×9.5 cm, and all wounds were accompanied by tendon exposure. 5 patients also had local bone exposure, and 10 patients had varying degrees of local infection. All patients were treated with wound debridement and continuous closed negative pressure drainage to control infection. After controlling the wound infection, an equally large temporal superficial fascia tissue flap was designed and cut according to the size of the wound to repair the wound. At the same time, a scalp split thick skin was taken to cover the fascia flap.Results:All 19 patients with superficial temporal fascia flaps survived, while 2 patients had poor skin flap survival due to subcutaneous hematoma. After re-grafting, the wound healed. After follow-up for 6-24 months, all patients were satisfied with the appearance of the anterior tibial region and had good recovery of ankle joint function. The supply valve area was concealed, without obvious scars, hair loss, baldness and other complications.Conclusions:The use of free superficial temporal fascia flap combined with split thick skin transplantation for repairing anterior tibial wounds has the advantages of strong anti infection ability, thin fascia flap, concealed donor site, and reconstruction of supporting ligaments. It is an ideal repair method for repairing difficult to heal wounds in the anterior tibial area.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To explore the factors affecting the prognosis of severe pediatric acute respiratory distress syndrome (ARDS) after receiving extracorporeal membrane oxygenation (ECMO) support.Methods:It was a multicenter prospective observational study. A total of 95 children with severe ARDS who were treated with ECMO salvage therapy from January 2018 to December 2022 in 9 pediatric ECMO centers in China were enrolled in the study. The general data, disease severity, organ function, comprehensive treatment and prognosis were recorded, and they were divided into survival group and death group according to the outcome at discharge. T test, chi-square test, multivariate Logistic regression and mixed linear model were used to analyze the relationship among baseline before ECMO treatment, some important indicators (pediatric critical scores, platelet count, albumin, fibrinogen, etc) during ECMO treatment and prognosis. Results:Among the 95 children with severe ARDS who received ECMO, 55 (58%) were males and 40 (42%) were females, aged 36.9 (0.5, 72.0) months. Twelve children (13%) were immunodeficient. Sixty-eight (72%) children were treated with venous artery (VA) mode and 27 (28%) with venous vein (VV) mode. The discharge survival rates of overall, VA, and VV mode children were 51% (48/95), 47% (32/68), and 59% (16/27), respectively. The number of immunodeficient children in the death group was higher, and there were lower pediatric critical scores, platelet count, albumin, fibrinogen and arterial oxygen partial pressure/fraction of inspired oxygen (PaO 2/FiO 2), higher ventilator driving pressure (ΔP), oxygenaion index (OI), and longer ARDS duration before ECMO (all P<0.05). There were no statistically significant differences in other indicators, including age, gender, weight, and ECMO mode among different prognostic groups (all P>0.05). High ΔP, high OI, low P/F, and low albumin were high-risk factors affecting prognosis(all P<0.05). After further grouping, it was found that ΔP≥25 cmH 2O (1 cmH 2O=0.098 kPa), P/F≤67 mmHg (1 mmHg=0.133 kPa) and OI≥35 were the thresholds for predicting poor prognosis ( P<0.05). From 24 h after ECMO, there were significant differences in ΔP, P/F and OI between the dead group and the survival group (all P<0.05), and the differences gradually increased with the ECMO process. The platelet level was significant from 7 days after ECMO ( P<0.05) and gradually expanded. Blood lactate levels showed a significant difference between the 2 groups on before and after ECMO ( P<0.05) and gradually increased from 24 h after ECMO. Conclusions:The risk factors affecting the prognosis of severe ARDS in ECMO include high ΔP, high OI, low P/F and low albumin purification therapy before ECMO. The gradual decrease of ΔP, OI and increase of P/F from 24 h of ECMO predicted a good prognosis, while the gradual increase of lactate after ECMO application showed a poor prognosis.

Objective To investigate the effect of cervical manual stratified anastomosis and anastomosis with tube stapler on the recent complications in thoracic laparoscopy combined with radical resection of esophageal cancer.Methods From February 2019 to April 2022,a total of 196 patients who underwent endoscopic surgery for esophageal cancer who met the study criteria were divided into the manual group(87 cases)and the tubulostomy group(109 cases)according to the different ways of gastro-esophageal cervical anastomosis.The incidence of cervical surgery time,total operation time,postoperative anastomotic fistula,anastomotic stenosis and other complications of the two groups were evaluated,and the differences in treatment effects between the two groups were compared.Results The preoperative basic conditions of patients in the manual group and the tube kiss group were comparable,and the cervical anastomosis time in the tube kiss group[(23±3.57)min]was shorter than that in the manual group[(31±4.5)min](P＜0.05),but there was no statistical significance in the overall operation time between the two groups(P＞0.05).The comparison of postoperative anastomotic fistula and anastomotic stenosis between the two groups showed that the manual group was significantly lower than the tube kiss group,and the difference was statistically significant(P＜0.05).Conclusion In thoracic laparoscopic combined with esophageal cancer surgery,cervical manual stratified anastomosis can reduce the incidence of postoperative anastomotic complications.

Objective To explore the predictive value of artificial intelligence(AI)quantitative model for pathological subtypes of stage Ⅰ invasive lung adenocarcinoma with ground glass nodule(GGN).Methods A total of 118 cases(124 lesions)of GGN patients with stage Ⅰ invasive lung adenocarcinoma confirmed by surgery and pathology were analyzed retrospectively,and they were divided into lepidic predominant adenocarcinoma(LPA)group(46 lesions)and non-lepidic predominant adenocarcinoma(n-LPA)group(78 lesions)according to the pathological subtype results.Some relevant AI quantitative parameters were recorded,including the longest diameter,total volume,the percentage of solid volume,total mass,the percentage of solid mass,maximum CT value,minimum CT value,and average CT value.The independent predictors of n-LPA were screened by univariate and multivariate logistic regression analysis,the independent risk factors were quantified by Nomogram,and the diagnostic efficiency of the model was evaluated by using receiver operating characteristic(ROC)curve.Results Binomial logistic regression analysis showed that the percentage of solid mass[odds ratio(OR)=1.965,95％confidence interval(CI)1.515-2.549]and average CT value(OR=1.020,95％CI 1.004-1.036)were independent predictors of n-LPA(P＜0.05).The Nomogram to quantify the independent risk factors showed that the above prediction model was in good agreement with the actual results,and the C-index value was 0.872(95％CI 0.791-0.953).ROC curve analysis showed that the diagnostic performance of the combination of the above two indexes[area under the curve(AUC)=0.829]was better than that of the solid mass percentage(AUC=0.788)and the average CT value(AUC=0.765)of the single indexes,and the corresponding sensitivity and specificity were 87.2％and 84.8％,respectively,which were consistent with the pathological results(Kappa=0.667).Conclusion The percentage of solid mass and the average CT value in the AI quantitative model can effectively help predict the pathological subtypes of GGN stage Ⅰ invasive lung adenocarcinoma,and the combination of the above two indicators can improve the differential diagnosis efficiency of CT between LPA and n-LPA.
