Objective To conduct an epidemiological survey of common congenital heart disease(CHD)among children in ethnic minority areas in southeastern Guizhou and to explore the influencing factors of delayed medical treatment.Methods From January 2019 to July 2022,18 850 children aged 3 months to 14 years in Qiandongnan Miao and Dong Autonomous Prefecture were selected;105 children with CHD were included in the training set,and they were divided into delayed group(80 cases)and non-delayed group(25 cases)according to whether or not to delay medical treatment.In addition,children with CHD(35 cases)from July 2022 to December 2022 were included in the validation set.The general data of the subjects in the two groups were compared and ana-lyzed.Multivariate logistic regression was performed and risk scoring model was constructed.Results The preva-lence of CHD in 18 850 children was 5.57‰(105/18 850),with the highest prevalence in Liping County,and the lowest in Huangping County.The proportion of children with secondary atrial septal defect was the highest,and that of the aortic valve malformation was the lowest.Among the complex cases of CHD,the proportion of children with single type was the highest,and that of children with three or more types were the lowest.Among children with CHD,the rate of delayed medical treatment was 76.19% (80/105).The median delay in medical treatment was 12 months,with an average of(18.78±4.77)months.Multifactor logistic regression analysis showed that heart murmur(level 2～3),less-educated(primary and secondary school)guardian,family per capita income<2 000 yuan,and frequent drinking of the guardian were independent risk factors for delayed medical treatment(P<0.05),and commercial settlement of medical expenses was independent protective factor(P<0.05).Risk scoring model divided the children into three groups:low risk(≤80 points),medium risk(>80 points and≤134 points)and high(>134 points)risk group.The evaluation of the model show that it was accurate,effective,safe,and reliable.Conclusion The highest prevalence is observed in Liping County.The proportion of children with secondary atrial septal defect and the proportion of children with single type are the highest.Delayed medical treat-ment is found in most of the children with CHD.Cardiac murmur,education background of the guardian,per capita family income,guardian alcohol consumption,and medical expense settlement method are all independent influencing factors for delayed medical treatment.

Objective To investigate the knowledge,demand,and use of clinical practice guide-lines(CPGs)among anesthesia professionals in Gansu province,and to explore the strategies and barriers during the implementation process.Methods A questionnaire survey was conducted to investigated the knowledge,demand,and use of CPGs,as well as the strategies and barriers during the process of guideline implementation.Statistical analysis was applied to the collected data.Results A total of 339 valid question-naires were collected,96.8%of the respondents were aware of the guidelines,and the majority of the re-spondents(86.4%)consulted the guidelines when they encountered problems in clinical practice.The main barriers for guideline utilization were identified as lack of convenience(70.2%),limited availability chan-nels(64.3%)or restricted access rights(56.9%)to obtain the guidelines,inadequate training(31.3%),and language barriers(21.5%).Multiple forms of assisting guideline use and opening up guideline access were considered by most respondents as important ways to promote guideline implementation.Conclusion Anesthesia professionals in Gansu province demonstrated good levels of awareness and compliance with guidelines.However,the primary barriers to utilization were attributed to the guidelines themselves or diffi-culties in accessing them.It is recommended to establish a national guideline clearinghouse,provide imple-mentation tools,and enhance healthcare professional training to facilitate the promotion and application of guidelines in the future.

Objective:To analyze the short-term clinical efficacy and safety of arsenic trioxide (ATO) combined with a modified N7 induction regimen in the treatment of children with high-risk neuroblastoma (NB).Methods:This study was a prospective, single-arm, multicenter phase Ⅱ clinical study. Sixty-seven high-risk NB children from eight units of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, Wuhan Children′s Hospital of Tongji Medical College of Huazhong University of Science and Technology, First Affiliated Hospital of Guangxi Medical University, Hainan General Hospital, Affiliated Hospital of Guangdong Medical University, Kunming Children′s Hospital, Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, and Guangdong Provincial Agricultural Reclamation Center Hospital were enrolled from January 2019 to August 2023 and were treated with ATO combined with a modified N7 induction regimen. The efficacy and adverse effects at the end of induction chemotherapy were assessed and analyzed, and the differences in the clinical characteristics were further compared between the treatment-responsive and treatment-unresponsive groups by using the Fisher′s exact test.Results:Among 67 high-risk NB children, there were 40 males (60%) and 27 females (40%), with the age of disease onset of 3.5 (2.6, 4.8) years. Primary NB sites were mostly in retroperitoneum (including adrenal gland) (56/67, 84%) and the common metastases sites at initial diagnosis were distant lymph node in 25 cases (37%),bone in 48 cases (72%),bone marrow in 56 cases (84%) and intracalvarium in 3 cases (4%). MYCN gene amplification were detected in 28 cases (42%). At the end of induction, 33 cases (49%) achieved complete remission, 29 cases (43%) achieved partial remission, 1 case (1%) with stable disease, and 4 cases (6%) were assessed as progressive disease (PD). The objective remission rate was 93% (62/67) and the disease control rate was 94% (63/67). The percentage of central system metastases at the initial diagnosis was higher in the treatment-unresponsive group than in the treatment-responsive group (2/5 vs. 2% (1/62), P=0.013), whereas the difference in MYCN gene amplification was not statistically significant between two groups (3/5 vs.40% (25/62), P=0.786). Grade Ⅲ or higher adverse reactions during the induction chemotherapy period were myelosuppression occurred in 60 cases (90%), gastrointestinal symptoms occurred in 33 cases (49%), infections occurred in 20 cases (30%), hepatotoxicity occurred in 4 cases (6%), and cardiovascular toxicity occurred in 1 case (2%). There were no chemotherapy-related deaths. Conclusion:ATO combined with N7-modified induction regimen had a superiority in efficacy and safety, which deserved further promotion in clinical practice.

BackgroundPatients with depressive disorder commonly experience sleep disturbances. Previous studies have indicated that group exercise therapy is beneficial in alleviating depressive symptom among patients with depressive disorder. However， there is a lack of research on the impact of group exercise therapy on improving sleep quality in patients with depressive disorder. ObjectiveTo explore the impact of group exercise therapy on sleep quality in patients with acute mild-to-moderate depression during the acute phase， so as to provide references for clinically improving the sleep quality of patients with mild to moderate depressive disorder during the acute phase. MethodsFrom December 2018 to July 2021， patients with mild-to-moderate depressive disorder during the acute phase （n=40）， who met the diagnostic criteria for depressive disorder according to International Classification of Diseases， tenth edition （ICD-10） ，were recruited from the outpatient clinic of Beijing Anding Hospital， Capital Medical University. All participants underwent an 8-week moderate-intensity group exercise therapy program comprising three sessions per week， each lasting 60 minutes. Assessments were conducted at baseline and after 2， 4， 6 and 8 weeks of intervention using Visual Analogue Scale （VAS）， Hamilton Depression Scale-17 item （HAMD-17） and Pittsburgh Sleep Quality Index （PSQI）. The reduction scores at each time point relative to baseline treated as the dependent variables， time as the independent variable， baseline scores as covariates， with time as a fixed effect and baseline values as random effects. Data were analyzed using a linear mixed-effects model. ResultsThe PSQI scores of patients at baseline， 2， 4 ， 6 and 8 weeks after the intervention were （10.62±5.12）， （9.07±3.58）， （7.39±3.66）， （6.54±3.84） and （5.50±3.41）， respectively. The results of linear mixed effect model analysis showed that after 2， 4， 6 and 8 weeks of intervention， patients scored lower than baseline， with statistically significant differences observed in all cases （P<0.01）. The HAMD-17 sleep fcctor scores at baseline， 2， 4， 6 and 8 weeks were （2.25±1.56）， （2.06±1.49）， （1.36±1.27）， （1.22±1.46） and （0.97±1.34）， respectively. The results of linear mixed effects model analysis showed that the HAMD-17 sleep factor scores of 4， 6 and 8 weeks of intervention were lower than that of baseline， and the difference was statistically significant （P<0.05 or 0.01）. The VAS scores at baseline， 2， 4， 6 and 8 weeks after the intervention were （3.18±2.17）， （4.74±2.22）， （6.01±2.31）， （6.54±2.16） and （7.90±1.64）， respectively. The results of linear mixed effect model analysis showed that VAS scores of 2， 4， 6 and 8 weeks of intervention were higher than baseline，and the difference was statistically significant （P<0.01）. ConclusionGroup exercise therapy may improve sleep quality and alleviate depressive symptoms in patients with mild-to-moderate depressive disorder during the acute phase. ［Funded by National Key Research and Development Plan Project （number， 2016YFC1307200）； Beijing Municipal Hospital Scientific Research and Cultivation Plan Project （number， PX2024070）］

Objective:To investigate the clinical effect of jujube core-shaped tissue resection technique in the treatment of alar reduction.Methods:A retrospective analysis was performed for the clinical data of patients who underwent alar reduction from February 2019 to June 2022. A spindle-shaped incision line was designed along the outer edge of the base of the nasal lobule, with a width of 4-5 mm and a length of 8-12 mm. The incision line was 1-2 mm away from the alar groove, and the inner side of the design line was extended to the inside of the nasal vestibule. After the incision was made, the subcutaneous tissue was undermining dissected with curved sharp scissors, and the shape of the extended excision tissue was similar to that of jujube core. After reduction, the incision was closed with vertical mattress suture. The surgical effect and complications were followed up after surgery, and an independent attending plastic surgeon evaluated the outcome and scarring based on photos before and at the last postoperative follow-up using the global aesthetic improvement scale (GAIS) and the Vancouver scar scale (VSS). GAIS is graded as 1, 2, 3, 4, and 5 points, and the lower the score, the better the improvement(≤3 points as effective improvement). VSS includes four parameters: color (0-3 points), thickness (0-4 points), vascular distribution (0-3 points), and softness (0-5 points). The higher the score, the more significant the scar is.Results:A total of 20 patients were enrolled, including 6 males and 14 females, aged 20 to 33 years, with an average age of 24.9 years. Before the operation, there were different degrees of alar flare and alar hypertrophy. After surgery, 13 patients had mild swelling, ecchymosis, which resolved after 3 days. There were no major complications as infection, incision dehiscence, and delayed healing. After 3 to 16 months of postoperative follow-up, 2 patients gradually developed cartilage deformation and affected the appearance of the nostrils 6 to 9 months after surgery due to the combination of rib-based rhinoplasty, and the satisfactory results were obtained after revision surgery. The symmetry of the nostrils was significantly improved. The GAIS score of 20 patients was (1.20±0.41) points, of which, 16 patients were rated as 1 point and 4 patients were rated as 2 points, all of which met the improvement criteria, and the VSS score was (1.45±0.60) points, in which the average score for color, thickness, vasculature and compliance are 0.60, 0.05, 0.55 and 0.30 points respectively.Conclusion:The application of jujube core-shaped tissue resection technique for alar reduction can increase the amount of tissue removal with the same incision width, which can not only fully narrow the alar effectively but also correct the hypertrophy of the alar tissue.

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 detection performance of left ventricular ejection fraction (LVEF) in patients with chronic renal failure (CRF) by an artificial intelligence (AI) model based on yolox framework integrating left ventricular segmentation and critical point detection.Methods:From January 2019 to June 2023, a total of 4 284 echocardiographic images of 2 000 adults aged 18-80 years without segmental wall motion abnormalities, structural heart disease, cardiac surgery or cardiomyopathy were collected in Henan Provincial People′s Hospital to delineate the endocardial membrane, as a training set, an AI model based on yolox framework integrating left ventricular segmentation and critical point detection was established. The images were divided into the training set( n=1 675) and the test set( n=325) in a ratio of about 5∶1. All 228 echocardiographic images of 100 normal adult volunteers who were treated in Henan Provincial Chest Hospital from May 2020 to May 2021 were collected as external test set validation. All 792 echocardiographic images of 204 patients treated in Henan Provincial People′s Hospital from April 2019 to June 2023 were continuously enrolled to evaluate the measurement efficiency of AI model. Spearman correlation statistical method was used to analyze the consistency of AI model measurement with manual measurement and TomTec software measurement methods of 3 senior echocardiographic professionals. Subjects were divided into clear image group, unclear image group, normal LVEF group and reduced LVEF group, the differences of general data between the two groups were compared. The correlation coefficient(ICC) within the group was calculated to analyze the consistency, so as to evaluate the model performance. Results:LVEF measured by AI model was significantly correlated with both manual measurement and TomTec model measurement ( rs=0.834, 0.826; all P<0.01). ICC values of the clear image group and the unclear image group were 0.96 and 0.97, respectively. ICC values for all subjects, normal LVEF group and reduced LVEF group were 0.96, 0.90 and 0.96, respectively. Conclusions:The AI model based on yolox framework integrating left ventricular segmentation and critical point detection has good diagnostic performance in the automatic measurement of LVEF in patients with CRF.

Objective:To analyze the new value of gastroscopy in the diagnosis of esophageal hiatal hernia(EHH).Methods:From March 7 to September 24 in 2019, 194 patients with gastroesophageal reflux disease who received endoscopy and high resolution esophageal manometry (HREM) at the Department of Gastroesophageal Surgery, the PLA Rocket Force Medical Center were selected. The transverse diameter of esophageal hiatus and the upward length of esophagogastric junction (EGJ) were measured under endoscopy, and the relevant data of reflux esophagitis (RE) and length and pressure of lower esophageal sphincter (LES) were collected. The value of traditional method under endoscopy and esophageal hiatus transverse diameter (EHTD) method under endoscopy in the diagnosis of EHH was compared. Independent sample- t test, rank sum test and chi-square test were used for statistical analysis. Results:The detection rate of EHH by EHTD method under endescopy was higher than that by traditional method under endoscopy and HREM method (60.8%, 118/194 vs. 14.9%, 29/194 and 37.1%, 72/194), and the detection rate of EHH by HREM method was higher than that by traditional method under endoscopy, and the differences were statistically significant ( χ2=86.75, 21.82, and 24.75; all P<0.001). The proportion of RE, the upward length of EGJ and the transverse diameter of esophageal hiatus of EHH patients diagnosed by traditional method under endoscopy and EHTD method under endoscopy were all higher than those of non-EHH patients (79.3%, 23/29 vs. 28.5%, 47/165; 49.2%, 58/118 vs. 15.8%, 12/76; 2.0 (2.0, 3.0) cm vs. 0.4(0, 0.7) cm, 0.7(0, 1.6) cm vs. 0(0, 0.6) cm; (2.60±0.71) cm vs. (1.88±0.44) cm, (2.30±0.45) cm vs. (1.51±0.29) cm); the minimum resting pressure of LES and resting pressure of LES were both lower than those of non-EHH patients(3.7(0.3, 12.1) mmHg (1 mmHg=0.133 kPa) vs. 9.1(3.3, 14.2) mmHg, 6.4(2.2, 12.5) mmHg vs. 10.8 (4.7, 15.5) mmHg; (9.70±7.92) mmHg vs. (14.92±10.30) mmHg, (11.36±7.79) mmHg vs. (18.44±11.78) mmHg); the length of intraperitoneal LES were shorter than that of non-EHH patients (0(0, 1.4) cm vs. 1.1(0, 1.7) cm, 0.3(0, 1.5) cm vs. 1.3(0.4, 1.8) cm); the length of LES of EHH patients diagnosed by EHTD method under endoscopy was shorter than that of non-EHH patients ((2.83±0.63) cm vs. (3.10±0.66) cm), and the differences were statistically significant ( χ2=26.53 and 22.31, Z=-8.26 and-5.04, t=5.26 and 13.67, Z=-2.14 and-2.71, t=-2.59 and-4.63, Z=-2.58 and-3.60, t=-2.96; all P<0.05). There were no significant differences in gender, LES length, intraperitoneal LES length, minimum resting pressure of LES, resting pressure of LES and residual pressure of LES between EHH patients diagnosed by EHTD method and traditional method under endoscopy (all P>0.05). Conclusions:Endoscopy plays a significant role in the diagnosis of EHH. EHTD method under endoscopy is more accurate in the diagnosis of sliding EHH, which is worthy of clinical reference.

Objective:To explore the risk factors of postoperative depression in patients with esophageal cancer, and to develop a risk prediction model which providing a theoretical basis for the early detection of depression in high-risk groups by clinical staff.Methods:From September 2022 to March 2023, at the South Campus of Affiliated Hospital of Jiangnan University, 269 hospitalized patients with esophageal cancer (191 in depression group, 78 in non-depression group) were selected as the model construction set. From March to May 2023, at the South Campus of Affiliated Hospital of Jiangnan University, 78 hospitalized patients with esophageal cancer were selected as the external validation set. The patients with Beck depression inventory-Ⅱ score ≥5 and depression diagnosed by two experts (chief psychiatrists of the Department of Psychiatry of Affiliated Hospital of Jiangnan University) were considered as depression and included in the depression group, and the other patients were enrolled in the non-depression group. The general data, blood routine examination, high-sensitivity C-reactive protein (hs-CRP), blood electrolytes, blood lipids, clinical symptoms (gastroesophageal reflux, sleep disturbance, appetite, etc.) and depression score were compared between the depression group and the non-depression group. Independent sample t-test and Mann-Whitney U test were used for statistical analysis. Multiple logistic regression model was performed to analyze the independent risk factors of postoperative depression in patients with esophageal cancer, and a risk warning model was constructed. The Hosmer-Lemeshow test and receiver operating characteristic curve (ROC) were used to evaluate the fitting degree and predictive efficiency of the model, and the cross-validation method was used to verify the effectiveness of the model. Results:The incidence of postoperative depression in patients with esophageal cancer was 71.0% (191/269). The total white blood cell count, hs-CRP, blood phosphorus β 2 microglobulin and the proportion of sleep disorders of the depression group were higher than those of the non-depression group (1.3 (1.1, 5.4) ×10 9/L vs. 0.9 (0.3, 1.1) ×10 9/L, 75.8 (54.8, 102.1) mg/L vs. 60.8 (3.6, 61.5) mg/L, (1.33±0.32) mmol/L vs. (1.02±0.19) mmol/L, (2.17±0.72) mg/L vs.(2.12±0.49) mg/L, 84.3% (161/191) vs. 33.3% (26/78), and the differences were statistically significant ( Z=9.24, 7.88, t=9.24, χ2=67.87 t=1.98; all P<0.001); hemoglobin, total platelet count, high-density lipoprotein (HDL) and the proportion of poor appetite were lower than those of the non-depression group ((119.91±24.51) g/L vs. (122.09±22.97) g/L, (203.43±58.45)×10 9/L vs. (311.55±83.54)×10 9/L, (1.04±0.30) mmol/L vs. (1.43±0.23) mmol/L, 73.3% (140/191) vs. 84.6% (66/78)), and the differences were statistically significant ( t=-2.00, -8.42 and -8.48, χ2=3.96; P=0.047, <0.001, <0.001, =0.047). The results of multifactorial logistic regression model analysis showed that sleep disorder ( OR=3.976, 95% confidence interval (95% CI 1.601 to 9.872)), loss of appetite ( OR=0.271, 95% CI 0.092 to 0.791), white blood cell count ( OR=31.808, 95% CI 2.879 to 351.401), hs-CRP ( OR=1.031, 95% CI 1.017 to 1.044), platelet count ( OR=0.990, 95% CI 0.982 to 0.997), and HDL ( OR=0.017, 95% CI 0.001 to 0.242) were independent influencing factors of postoperative depression in patients with esophageal cancer. The formula of risk warning model was probability of depression=1-1/{1+ exp[1.544+ 1.380×sleep disturbance (yes=1, no=0)-1.307×loss of appetite (yes=1, no=0)-0.010×platelet count (×10 9/L)-4.063×HDL (mmol/L)+ 0.030×hs-CRP (mg/L)+ 3.460×white blood cell count (×10 9/L)]}. The results of Hosmer-Lemeshow test showed that the model has a good fit ( χ2=2.01, P=0.981), with an area under the ROC of 0.949, a sensitivity of 0.874, and a specificity of 0.872. The cross-validation of the external validation set showed that the accuracy of the risk warning model was 67.9%. Conclusion:This study is a preliminary study on the risk warning model of postoperative depression in patients with esophageal cancer, which provides a novel approach for screening depression in patients with esophageal cancer after surgery.
