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 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.

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.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Objective:To measure the predictive value of miR-424 on the risk of sepsis complicated with acute respiratory distress syndrome(ARDS), and to explore its correlation with the prognosis of ARDS children.Methods:A prospective study was conducted.The data of children with sepsis (some complicated with ARDS), who were treated in Henan Provincial People′s Hospital (People′s Hospital, Zhengzhou University) were collected from February 2020 to February 2021.The incidence of ARDS and the fatality rate of ARDS children were recorded.Children were divided into survival group and death group according to whether death or not.The expression of miR-424 in peripheral blood mononuclear cells was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Pearson correlation analysis was made to investigate the relationship between the expression level of miR-424 and Pediatric Critical Illness Score(PCIS), Sequential Organ Failure Assessment(SOFA) score, oxygenation index(P/F ratio), C-reactive protein(CRP), procalcitonin (PCT), interleukin 6 (IL-6) and interleukin 8 (IL-8). The factors affecting the prognosis of ARDS children were analyzed by multivariate Logistic regression.Receiver operating characteristic curve(ROC)was used to assess the accuracy of miR-424 in early diagnosis of sepsis complicated with ARDS, and to measure the predicative value of miR-424 on the risk of death in sepsis patients with ARDS. Results:A total of 121 sepsis patients were included in this study, and 36 cases of them were complicated with ARDS.The expression level of miR-424(0.56±0.17)in the blood of sepsis patients complicated with ARDS was significantly lower than that of sepsis patients without ARDS (0.98±0.26)( t=8.776, P<0.001). The expression of miR-424 was negatively co-rrelated with IL-6( r=-0.627, P<0.01), IL-8 ( r=-0.651, P<0.01) and CRP( r=-0.472, P<0.05)in sepsis patients with ARDS.The expression of miR-424 was positively correlated with PCIS score( r=0.330, P<0.05), P/F ratio ( r=0.592, P<0.001) and albumin ( r=0.496, P<0.05) in sepsis patients with ARDS.The ROC showed that miR-424 [area under curve(AUC)=0.908, 95% CI: 0.856-0.960] could differentiate sepsis patients with ARDS from those without ARDS.Compared with that of the survival group(0.63±0.15), miR-424 of the death group decreased significantly(0.42±0.14)( t=3.890, P<0.05). The decreased miR-424 (AUC=0.845, 95% CI: 0.696-0.995)indicated an increased risk of death in children with ARDS.Multivariate Logistic regression analysis showed that miR-424( OR=0.001, P=0.033)and albumin ( OR=0.553, P=0.040) were independent risk factors for death in ARDS children. Conclusions:miR-424 can help with early diagnosis of sepsis complicated with ARDS, and can be used as a predictor of the prognosis of sepsis children complicated with ARDS.

Objective:To compare the differences of prostate cancer (PCa) and clinically significant prostate cancer (CsPCa) positive rate and postoperative complications between transperineal cognitive prostate biopsy (COG-TPBx) and transrectal cognitive prostate biopsy (COG-TRBx) based on biparametric magnetic resonance imaging (bpMRI).Methods:The data of 276 patients undergoing prostate biopsy from January 2019 to June 2021 in the First Affiliated Hospital of Nanjing Medical University were retrospectively reviewed. 157 patients underwent COG-TPBx(TPBx group) and 119 patients underwent COG-TRBx (TRBx group). The average age [(66.39 ± 8.31) vs. (66.30 ± 8.42)years], body mass index (BMI) [(23.85±2.49) vs. (23.68±2.61) kg/m 2], PSA values [9.43(1.47-19.80) vs. 8.94(0.66-19.99) ng/ml], prostate volume [37.92(13.99-167.40) vs. 40.78(11.67-188.21) cm 3], PSA density [0.21(0.04-1.17) vs. 0.20(0.04-1.04) ng/(ml·cm 3)], and suspicious digital rectal examination [17.20% (27/157) vs. 21.10% (25/119) ] were not significantly different between TPBx group and TRBx group. The positive rate of PCa, CsPCa, as well as post-biopsy complications of the two groups were compared. Results:There were no significant differences in the positive rate of PCa [49.68%(78/157) vs. 47.06%(56/119), P=0.666] and CsPCa [38.22%(60/157) vs. 34.45%(41/119), P=0.520] between the two groups. In stratification analysis, TPBx group has a significantly higher positive rate of both PCa [54.69%(35/64)] and CsPCa[43.75%(28/64)] in apex zone than TRBx group[39.62%(21/53) and 20.75%(11/53), all P<0.05). Moreover, the postoperative complications were not significantly different in TPBx group compared to that in TRBx group [10.19% (16/157) vs. 12.61%(15/119), P= 0.567]. Conclusions:Our investigations revealed that the overall positive rate of PCa, CsPCa, and the complications were not statistically different between COG-TPBx and COG-TRBx. COG-TPBx has a significantly higher positive rate of both PCa and CsPCa in apex zone.
