OBJECTIVES: To systematically evaluate the prevalence and risk factors of non-alcoholic fatty liver disease (NAFLD) in overweight and obese children and adolescents in China. METHODS: Databases including China National Knowledge Infrastructure, Wanfang Data, VIP Database, China Biomedical Literature Database, PubMed, Embase, Web of Science, and Cochrane Library were searched, from database inception to October 2024. Two researchers independently screened the literature, extracted data, and assessed the quality of the studies according to inclusion and exclusion criteria. A Meta analysis was conducted using Stata 16.0 software. RESULTS: A total of 42 studies involving 16 481 overweight and obese children and adolescents were included. The Meta analysis results showed that the prevalence of NAFLD among overweight and obese children in China was 43% (95%CI: 37%-48%). Factors associated with NAFLD included being male (OR=1.61, 95%CI: 1.17-2.04), increased weight (MD=10.33, 95%CI: 9.08-11.57), increased waist circumference (MD=5.49, 95%CI: 3.36-7.62), longer duration of obesity (MD=0.31, 95%CI: 0.02-0.61), higher body mass index (MD=3.11, 95%CI: 2.07-4.16), elevated fasting blood glucose levels (MD=0.17, 95%CI: 0.06-0.29), higher triglyceride levels (MD=0.32, 95%CI: 0.17-0.47), elevated total cholesterol levels (MD=0.15, 95%CI: 0.10-0.21), higher low-density lipoprotein cholesterol levels (MD=0.14, 95%CI: 0.04-0.23), increased alanine aminotransferase levels (MD=24.39, 95%CI: 18.57-30.20), increased aspartate aminotransferase levels (MD=12.49, 95%CI: 9.67-15.32), elevated serum insulin levels (MD=4.47, 95%CI: 2.57-6.36), higher homeostasis model assessment-insulin resistance (MD=0.45, 95%CI: 0.30-0.59), and elevated uric acid levels (MD=55.91, 95%CI: 35.49-76.32) (P<0.05). CONCLUSIONS The prevalence of NAFLD among overweight and obese children and adolescents in China is high. Male gender, increased weight, increased waist circumference, prolonged obesity duration, higher body mass index, dyslipidemia, and elevated levels of fasting blood glucose, liver enzymes, serum insulin, homeostasis model assessment-insulin resistance, and uric acid are potential risk factors for NAFLD in this population.

Objective To compare regional pulmonary ventilation and perfusion and ventilation/perfusion(V/Q)matching in different body positions using electrical impedance tomography(EIT).Methods Ten healthy experimental pigs were selected to collect their EIT lung ventilation and perfusion data in supine,prone,left lateral and right lateral positions.The EIT data underwent analysis and image reconstruction using MATLAB R2022b and EIDORS v3.9.The effective regions with ventilation and perfusion were determined and the V/Q matching regions were computed with the maximum pixel value 20％as the threshold.Comparisons were carried out over the V/Q matching indexes including V/Q match％,dead space％and shunt％and ventilation and perfusion distribution in regions of interest(ROIs)including ROI1,ROI2,ROI3 and ROI4 in different body positions.Results The differences in V/Q match％,dead space％and shunt％of the experimental animals in varied positions were not statistically significant(P＞0.05).The regional distribution of pulmonary ventilation and perfusion changed in different positions,and the regional distributions differed in ROIl,ROI2 and ROI3 for ventilation(P＜0.05)and in ROI1 and ROI2 for perfusion(P＜0.05).The ventilation and perfusion regions were distributed consistently with the gravity-dependent areas in supine and prone positions whereas conversely in the right and left lateral positions.Conclusion The V/Q matching indexes of one subject have high test consistency in different body positions;gravity-dependent areas varied with the changes of the body positions,which affected the distribution of pulmonary ventilation and perfusion regions;EIT can be used for measuring the changed pulmonary ventilation and perfusion due to different positions and determining the influences of position changes on pulmonary ventilation and perfusion and V/Q matching.[Chinese Medical Equipment Journal,2024,45(5):1-7]

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the value of preoperative vascular ultrasound parameters in predicting the postoperative lower extremity deep venous thrombosis (DVT) in patients with gynecological malignant tumors.Methods:Ninety-nine patients with gynecological malignant tumors, aged>18 yr, with body mass index<30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were selected. Vascular ultrasound examination was performed before surgery. The flow velocity and diameter of common femoral vein (CFV), deep femoral vein (DFV), popliteal vein (POV), and intermuscular vein (IMV) were recorded. Ultrasound examination of lower limb veins (including anterior tibial vein, posterior tibial vein, IMV, CFV, DFV, POV) were conducted at 1-8 days after surgery to determine whether a DVT occurred. The receiver operating charcateristic curve was used to evaluate the accuracy of each indicator in predicting the lower extremity DVT, and the cut-off value was determined based on the maximum principle of Jorden index. Results:The incidence of lower extremity DVT was 13.1%. The area under the curve (95% confidence interval) of the preoperative CFV flow velocity and diameter, DFV flow velocity and diameter, POV flow velocity and diameter, IMV flow velocity and diameter in predicting the lower extremity DVT were 0.769 (0.616-0.923) and 0.800 (0.644-0.950), 0.797 (0.641-0.954) and 0.771 (0.596-0.945), 0.806 (0.645-0.968) and 0.754 (0.606-0.903), 0.764 (0.615-0.914) and 0.818 (0.645-0.990), respectively ( P<0.05), and the predicted cut-off values were 27.13 cm/s and 11.93 mm, 19.31 cm/s and 10.15 mm, 16.04 cm/s and 8.79 mm, 14.39 cm/s and 8.68 mm, respectively, and the sensitivity and specificity were 90.0%, 71.4% and 90.0%, 74.3%; 90.0%, 74.3% and 90.0%, 68.6%; 90.0%, 82.9% and 90.0%, 72.9%; 90.0%, 70.0% and 80.0%, 87.1%, respectively. Conclusions:Preoperative vascular vascular ultrasound parameters can accurately predict the occurrence of postoperative lower extremity DVT in patients with gynecological malignant tumors.

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

ObjectiveTo explore the effects of body weight and waist circumference on static and dynamic balance function in overweight and obese adults. MethodsParticipants （n=103） were selected by cluster random sampling from the Hypoglycemic Weight Loss Clinic of the Endocrinology Department of the Third Affiliated Hospital of Sun Yat-sen University. All participants were assessed for basic data collection， biochemical test， body weight， waist circumference and height measurement， static balance function assessed by balance error scoring system （BESS） and dynamic balance function assessed by functional reach test （FRT）. The BESS score and FRT distance of all participants were compared among groups according to different BMI grades and WC grades. Multivariate linear regression was used to analyze the influencing factors of participants' dynamic and static balance functions. Results① With the increase of BMI grading， the BESS score showed an upward trend， and the difference between groups was statistically significant （P = 0.004）. The BESS score of normal WC patients was lower than that of central obesity patients （P < 0.001）， which indicated that compared with normal BMI， overweight and obese people had poor dynamic and static balance ability； ② With the BMI grading， the FRT distance increased， showing a downward trend （P < 0.001）. The FRT distance in normal WC patients was significantly higher than that in central obesity patients （P < 0.001）， which indicated that the static and dynamic balance ability of central obesity patients was worse than that of normal WC patients； ③ In BMI overweight group， the FRT distance decreased significantly with the increase of WC （P = 0.02）. The results showed that under the condition of no difference in BMI， Compared with normal WC， the dynamic and static balance ability of central obese patients was worse； ④ The influence of BESS score on BMI（B=4.12，P =0.027， 95% CI=0.48-7.75）and WC（B = 3.47，P = 0.046， 95% CI = 0.07 - 6.88）was significant. The influence of FRT distance on BMI（B = -5.68，P = 0.001， 95% CI = -8.95 - 2.41）and WC（B = -4.71，P = 0.003， 95% CI = -7.83 to -1.61）was significant， which indicated that the static and dynamic balance ability of obese people was worse with the increase of BMI， and the ability of dynamic and static balance of central obesity was worse than that of normal WC. ConclusionWaist circumference is an independent factor affecting the dynamic and static balance function of overweight and obese people. Under similar BMI， the dynamic balance function of central obese people is worse than that of people with normal waist circumference， leading to higher risk of falling.

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.
