Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

ObjectiveThis study explored the risk factors for malignant risks of pulmonary nodules based on clinical data，constructed an integrated traditional Chinese and Western medicine model for predicting malignant risks of pulmonary nodules， and visualized the prediction results by using a nomogram. MethodsBased on a cross-sectional survey study design，patients with pulmonary nodules who were hospitalized in the Department of Respiratory and Cardiothoracic Surgery of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2023 to January 2024 were included. The dataset was randomly divided into a training set and a validation set according to 7∶3. In the training set，predictive factors were selected through univariate Logistic regression analysis and Least Absolute Shrinkage and Selection Operator （LASSO） regression analysis，and Logistic regression models were built. The discriminative ability，calibration，and clinical decision-making curves of the Western medicine model and the integrated traditional Chinese and Western medicine prediction model were compared to select the optimal model，which was then visualized in a nomogram. ResultsThis study included a total of 366 patients，and they were divided into a training set （258 cases） and a validation set （108 cases）. Seven predictive factors were considered including age，preference for fatty and greasy foods，history of environmental or occupational exposure，Qi deficiency，Yang deficiency，nodule density，and nodule diameter. A Logistic regression model was constructed. A Western medicine model，defined as model1，was created using only age，history of environmental or occupational exposure，nodule density，and nodule diameter as predictive factors. In addition，an integrated traditional Chinese and Western medicine model，defined as model2，was created by adding preference for fatty and greasy foods， Qi deficiency，and Yang deficiency as predictive factors. Model2 demonstrated better predictive performance in both the training and validation sets. Its accuracy in training set was 0.740，with precision of 0.825， recall of 0.829， F1 score of 0.827， the area under the curve （AUC）of 0.865 （95% confidence interval （CI）：0.815-0.915）， and a Brier score of 0.122. The accuracy in validation set was 0.731， with precision of 0.776， recall of 0.831， F1 score of 0.803， AUC of 0.852 （95%CI：0.776-0.927）， and a Brier score of 0.149. The calibration curve and decision-making curve analysis showed that this model exhibited good consistency and clinical utility in prediction. The equation for the malignant probability of pulmonary nodules was defined as p=eY/(1+eY)，where Y=-4.187+0.022×（age）+1.079×（history of environmental or occupational exposure）+0.718×（preference for fatty and greasy foods）+ 1.403×（Qi deficiency）+0.732×（Yang deficiency）+0.349×（pure ground glass density nodules）+1.304×（partially solid density nodules）+0.148×（nodule diameter）. A nomogram was used for intuitive representation. ConclusionThis study develops a comprehensive assessment model for the malignant risk of pulmonary nodules， which integrates factors from traditional Chinese medicine and Western medicine. Embedding traditional Chinese medicine elements in the prediction model allows for a multidimensional assessment of relevant risk factors for nodule malignancy. This demonstrates good diagnostic performance and provides a reference for early identification of lung cancer.

Objective:To investigate the selection of treatment methods for renal tumors in pilots as well as the clinical significance of robot-assisted surgery by summarizing the process of robot-assisted surgery in the treatment of renal cell carcinoma in a pilot.Methods:The diagnosis, robot-assisted surgery and aeromedical assessment of a pilot with renal cell carcinoma were reported, and the related literature was reviewed.Results:The patient was a 44-year-old male transporter pilot, who was diagnosed with a left renal mass in the middle-lower pole of the kidney during a routine abdominal CT scan. After detailed preoperative evaluation that ruled out the possibility of distant metastasis and other surgical contraindications, the patient underwent robot-assisted laparoscopic partial nephrectomy in August 2022. The postoperative recovery went well, and renal function remained within normal limits at follow-ups. In March 2023, the pilot was concluded as qualified for flight after aeromedical assessment.Conclusions:Robot-assisted partial nephrectomy can significantly reduce surgical trauma, lower the risk of complications, and maximally preserve renal function. It is a good approach to renal tumors in pilots who can recover quickly.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective:To investigate the efficacy of tibiofibular-based reconstruction technique with single femoral tunnel for Fanelli type C posterolateral complex (PLC) injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 16 patients with Fanelli type C PLC injury admitted to Tianjin Hospital from July 2016 to July 2019, including 10 males and 6 females, aged 20-61 years [(36.5±13.9)years]. PLC reconstruction was performed by tibiofibular-based technique with single femoral tunnel using gracilis tendon and semi-tendinosus autografts. If the posterior and anterior cruciate ligaments (PCL/ACL) rupture were combined, arthroscopic single bundle reconstruction was performed simultaneously. If the posteromedial corner (PMC) injury was combined, PMC repair or reconstruction surgery was performed simultaneously. Operation time and intraoperative blood loss were recorded. When the bone needle and tunnel for PLC were drilled during the operation, the interference of the femoral tunnel through the cruciate ligament was observed under the arthroscope. Before and at 6 and 12 months after operation, the varus stability of the knee joint was evaluated with the difference of lateral joint space width of both knees and the International Knee Documentation Committee (IKDC) objective classification of varus stability of the knee joint; the external rotation stability was evaluated with the difference of external rotation angle of both knees and the IKDC objective classification of external rotation stability of the knee joint. Before, at 6 and 12 months after operation and at the last follow-up, IKDC 2000 subjective score and Lysholm score were compared. The occurrence of complications was observed.Results:All the patients were followed up for 12-36 months [24(15, 33)months]. The operation time was 100-220 minutes [175.0(111.3, 200.0)minutes], with intraoperative blood loss of 30-150 ml [(84.3±36.5)ml]. Intraoperative arthroscopy showed no interference of perforation between PLC and cruciate ligament femoral tunnel. The differences of lateral joint space width of both knees at 6 and 12 months after operation were 0.5(0.2, 1.4)mm and 0.6(0.2, 1.5)mm respectively, which were both significantly improved compared with 12.1(10.8, 12.6)mm before operation ( P<0.05), while there was no significant difference at 6 and 12 months after operation ( P>0.05). The IKDC objective classification of varus stability of the knee joint was grade A in 13 patients, grade B in two and grade C in one at 6 or 12 months after operation, and showed statistical difference from grade D in all the patients before operation ( P<0.01). At 6 and 12 months after operation, the difference of external rotation angle of both knees was -2.0(-3.2, 1.3)° and -1.4(-3.0, 1.7)° respectively, which were significantly improved compared with 16.8(13.9, 18.4)° before operation ( P<0.05), while there was no significant difference at 6 and 12 months after operation ( P>0.05). IKDC objective classification of external rotation stability of the knee joint was grade A in 14 patients, grade B in one and grade C in one at 6 or 12 months after operation, and showed statistical difference from grade C in 14 patients and grade D in 2 before operation ( P<0.01). At 6 and 12 months after operation and at the last follow-up, the IKDC 2000 subjective scores [(76.3±4.7)points, (80.3±4.4)points, (79.9±3.8)points respectively] and the Lysholm scores [(76.1±3.9)points, (81.1±4.3)points, (82.8±3.2)points respectively] were significantly improved compared with those before operation [(48.6±3.7)points and (52.6±2.4)points] ( P<0.05). The IKDC 2000 subjective scores and Lysholm scores were significantly improved at 12 months after operation and at the last follow-up than those at 6 months after operation ( P<0.05). There were no significant differences in the IKDC 2000 subjective scores and Lysholm scores at 12 months after operation and at the last follow-up ( P>0.05). There were no complications such as wound infection, vascular and nerve injury, joint stiffness or ectopic ossification. Conclusion:For Fanelli type C PLC injury, tibiofibular-based reconstruction technique with single femoral tunnel reduces the interference between the lateral femoral tunnels, significantly improves the varus and external rotation stability and the function of the knee joint, and has few complications and satisfactory short-term clinical efficacy.

ObjectiveTo evaluate the reliability and validity of the Dampness Syndrome Scale of Chinese Medicine （DSSCM） among patients with persistent asthma， and to explore the correlation between dampness syndrome and clinical characteristics of persistent asthma. MethodsA cross-sectional survey was conducted. Basic information， examination results， DSSCM， Asthma Control Test （ACT）， Generalized Anxiety Disorder-7 （GAD-7）， and Patient Health Questionnaire-9 （PHQ-9） scores were collected from 206 patients with persistent asthma to evaluate the reliability and validity of DSSCM and to explore the correlation between dampness syndrome and clinical characteristics. ResultsThe mean score of DSSCM among 206 patients was 14.59 ± 10.53. The overall Cronbach α coefficient and Spearman-Brown split-half reliability coefficient of the scale were both greater than 0.8， and the success rate of scale convergent and discriminant validity calibration were greater than 80%. The confirmatory factor analysis showed that the χ²/df was 2.309， and the root mean square error of approximation （RMSEA） was 0.08； the root mean square residual （RMR） was 0.049， whereas the comparative fit index （CFI）， the goodness of fit index （GFI）， the adjusted goodness of fit index （AGFI）， the normed fit index （NFI） and the incremental fit index （IFI） were less than 0.9. Correlation analysis showed that DSSCM scores were positively correlated with disease duration， GAD-7 scores， and PHQ-9 scores （P＜0.05）， and negatively correlated with ACT scores （P＜0.01）. The DSSCM scores were significantly different between patients with different disease severity （H = 10.92， P = 0.01）， and the DSSCM scores of allergic patients were higher than those of non-allergic patients （Z = -4.19， P＜0.001）. ConclusionDSSCM has acceptable reliability and validity for patients with persistent asthma. The scores of DSSCM correlated with the disease duration， ACT score， GAD-7 score， PHQ-9 score， disease severity and allergic status of persistent asthmatics.

ObjectiveTo evaluate the clinical efficacy and safety of Xianqi Qinglong Formula （仙芪青龙方， XQF） in the treatment of cough variant asthma （CVS） patients with lung and kidney deficiency and exuberant wind-induced spasm and tension syndrome. MethodsA randomized， positive-controlled， non-inferiority clinical trial was designed. Totally， 102 CVS patients with lung and kidney deficiency and exuberant wind-induced spasm and tension syndrome were randomly divided into a treatment group （52 cases） and a control group （50 cases）. The treatment group was given XQF granules orally， 1 dose per day， 2 bags each time （9.25 g/bag）， twice a day， after breakfast and dinner； the control group was given XQF granules placebo orally combined with inhaled fluticasone propionate inhalation aerosol （125 μg each time， twice a day）. Both groups were treated for 12 weeks and followed up for 12 weeks， with a total of 24 weeks. The primary outcome was the cough symptom score （including daytime， nighttime and total score）， evaluated before treatment （at enrollment）， during treatment （after the 6th week of enrollment）， at the end of treatment （after the 12th week of enrollment）， and at the end of follow-up （after the 24th week of enrollment）. The non-inferiority was determined by the lower limit （LCL） of the unilateral 95% confidence interval. The secondary outcomes included cough relief and disappearance， total score of TCM syndrome， cough visual analogue （VAS） score， Leicester Cough Questionnaire （LCQ） score， and lung function indicators including forced expiratory volume in 1 second （FEV1）， percentage of predicted forced expiratory volume in 1 second （FEV1%pred）， forced vital capacity （FVC）， and peak expiratory flow （PEF）. Blood routine and liver and kidney function were tested before and after treatment， and the adverse events were recorded. ResultsA total of 101 patients were included in the full analysis set （FAS）， including 52 cases in the treatment group and 49 cases in the control group. After treatment， the daytime， nighttime and total cough symptom scores during treatment， at the end of treatment and at the end of follow-up all decreased in both two groups （P＜0.01）. The unilateral 95% LCL of the total cough symptom scores during treatment， at the end of treatment and at the end of follow-up of the two groups were -0.14， -0.47 and -0.27 （95% LCL all＞-0.6）. There were no significant differences in the cough relief rate， cough disappearance rate， cough relief days and cough disappearance days between the two groups at each time point （P＞0.05）. Compared to those before treatment， the TCM syndrome scores and cough VAS scores during treatment， at the end of treatment and at the end of follow-up decreased in both groups， while the LCQ scores increased （P＜0.01）， but there were no significant differences in FEV1， FEV1%， FVC and PEF before and after treatment （P＞0.05）. There were no significant differences in TCM syndrome scores， cough VAS scores， LCQ scores， FEV1， FEV1%， FVC， and PEF between the two groups at each time point （P＞0.05）. No clinically significant abnormal liver and kidney function were found in the two groups before and after treatment. ConclusionXQF is not inferior to fluticasone propionate inhalation aerosol in relieving cough symptoms， reducing cough scores， decreasing the number of cough attack days， and improving the quality of life when treating CVS patients with lung and kidney deficiency and exuberant wind-induced spasms and tension syndrome， and relatively safe.

Clinical research coordinator (CRC) can improve the efficiency of clinical research, ensure the accuracy and reliability of the research process, as well as the standardized implementation of research projects and the safety of subjects. However, the CRCs dispatched by the site management organization have problems such as high liquidity, uneven quality, low work initiative, and high management costs. Since 2004, a research hospital in South China had started to employ CRCs by itself, exploring and forming three self-employed CRC management modes: hospital employ-hospital manage, researcher employ hospital manage, and researcher employ-third-party labor dispatch agency manage. The CRCs under hospital employ-hospital manage mode were recruited and selected by the hospital. The hospital established a labor relationship with CRC, and the hospital′s personnel department was responsible for salary distribution and promotion management of professional titles/positions. The relevant labor costs were borne by the hospital′s funds, and the salary standards were also formulated by the hospital. This type of CRC could participate in the promotion of health technology series titles. The CRCs under researcher employ-hospital manage mode were recruited and selected by the researcher. The hospital established a labor relationship with them. The relevant labor costs were borne by the research funding, and the researchers determined the specific salary standards for CRCs based on the salary guidance plan formulated by the hospital. These kind of CRCs could not be promoted to professional titles in hospitals. The CRCs under researcher employ-third-party labor dispatch agency manage mode were recruited and selected by researchers. The third-party labor dispatch agency established an employment relationship with them and provided personnel services. The relevant labor costs were borne by the research funding, and the researchers formulated their own salary standards. Such CRCs could not be promoted to professional titles in hospitals. As of July 2023, the number of self-employed CRCs in the hospital had reached 185, with 75.8% having a bachelor′s degree or above and an average work experience of 4.58 years. Among them, there were 26 people in the hospital hiring-hospital management mode, 45 people in the researcher hiring-hospital management mode, and 114 people in the researcher hiring-third-party labor dispatch agency management mode. These measures had fully released management efficiency, effectively met manpower needs, promoted rapid growth in the number of clinical research projects, and reduced management costs through third-party labor dispatch mode, which could provide references for CRC management in clinical trial institutions of China.
