ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Background The moderation role of environmental factors in the spread of hand-foot-and-mouth disease (HFMD) has attracted much attention, but the existing conclusions are inconsistent. For example, some scholars believe that high temperature, high humidity, and high concentrations of fine particulate matter (PM_2.5) and nitrogen dioxide (NO₂) increase the risk of HFMD, but other scholars have reached the opposite conclusion, or believe that there is no significant relationship. Objective Based on distributed lag nonlinear model (DLNM), to investigate the relationship between the incidence of HFMD and meteorological and air pollutant variables in Lianyungang City, and to provide scientific basis for early warning. Methods Daily data of meteorological factors and air pollutants in Lianyungang City from 2021 to 2024 were retrieved. Meteorological factors included average daily temperature, average wind speed, average air pressure, and relative humidity. Air pollutant indicators included PM_2.5, inhalable particulate matter (PM₁₀), carbon monoxide (CO), sulfur dioxide (SO₂), NO₂, and ozone (O₃). Spearman correlation analysis was used to analyze their correlations with HFMD, and the R package (version 4.3.1) dlnm was used to construct a DLNM model. Results During the study period, a total of 10503 cases were reported, with a male to female ratio of 1.47∶1 and the highest proportion of scattered children (49.97%). The Spearman correlation analysis results showed that daily average temperature (r=0.40), relative humidity (r=0.17) and O₃ (r=0.14) were positively correlated with the incidence of HFMD (all Ps<0.01), while average air pressure (r=−0.34), PM_2.5 (r=−0.24), PM₁₀ (r=−0.24), CO (r=−0.22), and NO₂ (r=−0.06) were negatively correlated with it (all Ps<0.05). There was no statistical relationship of SO₂ and average wind speed with the incidence of HFMD (both Ps>0.05). The cumulative risk effect was greatest when the daily average temperature was 28.50 ℃ (CRR=4.63, 95%CI: 2.68, 8.01). The average wind speed below 0.50 m·s⁻¹ and in the range of 2.50-3.50 m·s⁻¹ showed an acute risk effect, and low pressure (below 1016.00 hPa) could immediately increase the risk of the disease. The cumulative risk effect was greatest when the relative humidity was 100% (CRR=3.16, 95%CI: 1.77, 5.65). The greatest cumulative protective effects of PM_2.5 and PM₁₀ were present at concentrations of 158.00 μg·m⁻³ (CRR=0.12, 95%CI: 0.01, 0.99) and 561.50 μg·m⁻³ (CRR=0.01, 95%CI: 0.01, 0.99) respectively. The protective effect of CO was the strongest at the highest concentration (67.00 μg·m⁻³) (RR=0.67, 95%CI: 0.34, 0.64). The cumulative protective effects of SO₂ and NO₂ were both most significant at the concentration of 0.50 μg·m⁻³. Low concentrations of O₃ (below 48.00 μg·m⁻³) showed a risk effect, and the single-day protective effect was significant when the concentration was 141.00 μg·m⁻³. Conclusion There is a nonlinear and hysteretic relationship between environmental factors and the incidence of HFMD. A rational and efficient early warning and prevention and control system can be constructed accordingly.

Objective To evaluate the application of high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)in identifying high-risk features of intracranial atherosclerotic plaques,and to analyze the correlation between plaque characteristics and stroke recurrence under varying degrees of stenosis.Methods The data from 368 patients with intracranial atherosclerotic stenosis(ICAS)across two centers were retrospectively analyzed.Based on the degree of stenosis,all patients were categorized into mild-to-moderate stenosis group(luminal stenosis<70%,n=155)and severe stenosis group(luminal stenosis≥70%,n=213).HRMR-VWI images and clinical information of the patients were collected and analyzed,and the culprit plaques were quantitatively analyzed.Univariate and multivariate logistic regression analyses were employed to identify the risk factors for stroke recurrence,and the predictive performance was evaluated using the area under the curve(AUC)of the receiver operating characteristic(ROC)curve.Results Higher normalized wall index(NWI)[odds ratio(OR)=1.082,95%confidence interval(CI)1.050-1.118,P<0.05]and the presence of intraplaque hemorrhage(IPH)(OR=1.843,95%CI 1.120-3.036,P<0.05)were risk factors for stroke recurrence in all patients.And these two factors were also significant in the mild-to-moderate stenosis group(NWI:OR=1.088,95%CI 1.009-1.186,P<0.05;IPH:OR=4.049,95%CI 1.227-16.065,P<0.05).A predictive model for stroke recurrence was constructed using the combination of IPH and NWI,with the best performance in the mild-to-moderate stenosis group(AUC=0.813,95%CI 0.723-0.906).Conclusion In patients with luminal stenosis<70%,the increase of NWI and the presence of IPH have been validated as significant and effective indicators for predicting stroke recurrence,demonstrating notable predictive performance.In contrast,among patients with luminal stenosis≥70%,the utility of plaque characteristics in predicting stroke recurrence is relatively lower,indicating that the correlation between plaque characteristics and stroke recurrence varies across different degrees of stenosis.

Objective To investigate the effectiveness and safety of electroconvulsive therapy(ECT)in reducing suicidal ideation and depressive symptoms of major depressive disorder patients,as well as its effect on cognitive function.Methods A total of 160 adolescent patients with major depressive disorder were recruited for this study.The ECT group(n=81)received conventional antidepressant medication combined with 8 sessions of electroconvulsive therapy,and the control group(n=79)received conventional antidepressant medication only.Depressive symptoms,suicidal ideation,and cognitive functioning were assessed using 17-item Hamilton rating scale for depression(HAMD-17)and self-rating idea of suicide scale(SIOSS),at baseline(before ECT),after ECT,and at 2 and 6 weeks after treatment.The Montreal cognitive assessment(MoCA)was used to evaluate the cognitive function of the patients,and the patients were followed up for side effects such as dizziness and nausea.Results Generalized estimating equation(GEE)analysis of HAMD-17 and SIOSS scores showed significant group×time interaction effects(P<0.01).Both groups exhibited a reduction in HAMD-17 scores before and after treatment(scores at four time points:ECT group 24.59±4.56 vs.13.25±4.32 vs.6.20±1.95 vs.3.62±2.04,control group 23.48±3.66 vs.15.42±3.11 vs.10.10±2.05 vs.4.68±2.01;P<0.01).The mean difference in HAMD-17 scores before and after treatment was-9.62±3.13 in the ECT group,and was-8.16±1.71 in the control group.Additionally,suicidal ideation reduced in both groups after treatment(SIOSS scores at four time points:ECT group 18.57±2.85 vs.10.93±3.52 vs.8.02±2.79 vs.3.70±1.96,control group 18.97±3.03 vs.15.51±2.98 vs.11.11±2.18 vs.6.44±1.78;P<0.01).For cognitive function scores,there was no interaction between group and time(P=0.21),the difference in the change in MoCA scores at different follow-up time points was significant(P<0.01),and the difference in the change in MoCA scores between the two groups was not significant(P=0.05),and the cognitive functions of the two groups could be restored to the baseline level at 6 weeks after treatment.No severe side effects were reported in either group of patients during the study.Conclusions Our findings confirm that ECT is effective and safe for improving suicidal ideation and depressive symptoms in adolescents with major depressive disorder.The impairment of cognitive function by ECT in adolescent patients with major depressive disorder is reversible.

Objective:To explore the safety and efficacy of laparoscopic-assisted radical surgery in the treatment of metachronous multiple primary colorectal cancer (MCC).Methods:A retrospective analysis was conducted on 27 MCC patients undergoing laparoscopic-assisted radical surgery (laparoscopic group) and 36 MCC patients undergoing open radical surgery (open group) from Jan 2012 to Jan 2022 at the Department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences.Results:The laparoscopic group was superior to the open group in terms of intraoperative blood loss [(53.7±111.5) ml vs. (132.5±154.9) ml, t=-2.241, P=0.029], time to first postoperative flatus [(2.2±0.7) days vs. (3.5±0.6) days, t=-7.752, P<0.001], time to first postoperative defecation [(2.9±0.6) days vs. (4.3±0.6) days, t=-8.841, P<0.001], and postoperative hospital stay [(7.2±2.4) days vs. (10.6±3.5) days, t=-4.518, P<0.001]. There were no significant differences between the two groups in terms of operation time, number of lymph nodes dissected, positive rate of specimen margin, resection rate of previous colorectal cancer anastomotic stoma, and incidence of postoperative complications (all P>0.05). Conclusion:Laparoscopic surgery is a safe and minimally invasive alternative to open surgery for MCC patients.

Objective:To explore the risk factors for severe acute kidney injury (AKI) in children with sepsis in the pediatric intensive care unit (PICU) and construct a prediction model to assist early clinical identification.Methods:A retrospective analysis was performed on clinical data of 987 children with sepsis admitted to the PICU of Hunan Children′s Hospital from July 1, 2018 to January 31, 2021. Children who developed severe AKI during hospitalization were included in the AKI stage 2-3 group ( n=228), and the remaining were included in the No-AKI/AKI stage 1 group ( n=759). General information and biochemical indicators were compared between the two groups. Logistic regression analysis was used to identify risk factors for severe AKI in children with sepsis, and a prediction model and nomogram were established. Results:The mortality rate in the AKI stage 2-3 group was 2.49 times that of the No-AKI/AKI stage 1 group [31.1%(71/228) vs 12.5%(95/759), P<0.05]. Compared with the No-AKI/AKI stage 1 group, the AKI stage 2-3 group had lower levels of platelet count (PLT), total protein (TP), albumin (ALB), antithrombin Ⅲ (AT3), and fibrinogen (FIB), but higher levels of lactate dehydrogenase (LDH), serum creatinine (SCr), blood urea nitrogen (BUN), magnesium ion (Mg 2+ ), activated partial thromboplastin time (APTT), fibrinogen degradation products (FDP), and D-dimer (D-D) (all P<0.05), with no significant difference in total bile acid (TBAC) ( P>0.05). Multivariate logistic regression analysis showed that decreased AT3 ( OR=0.989, 95% CI: 0.980-0.997, P=0.007), increased LDH ( OR=1.001, 95% CI: 1.000-1.001, P<0.001), increased SCr ( OR=1.051, 95% CI: 1.037-1.066, P<0.001), and increased BUN ( OR=1.099, 95% CI: 1.028-1.174, P=0.005) were risk factors for severe AKI in children with sepsis. The prediction model was Logist Pr=-3.184-0.012 X1+ 0.001 X2+ 0.050 X3+ 0.094 X4 ( X1=AT3, X2=LDH, X3=SCr, X4=BUN), with the optimal cut-off value of 0.374 (Youden index=0.560). A nomogram was constructed by binary assignment of predictive variables, with an area under the curve of 0.826 (95% CI: 0.790-0.861, P<0.001). Conclusions:The mortality rate of septic children with severe AKI in PICU is significantly increased. Decreased AT3, and increased LDH, SCr, and BUN are risk factors for severe AKI in children with sepsis. Clinicians should be alert to severe AKI when the predicted probability of the early warning model exceeds 0.374.

Objective:To investigate the clinical significance of CD105 and erythropoietin-producing hepatocellular receptor A2 (EPHA2) expressions in breast invasive ductal carcinoma and the effects of the combination of diabetes mellitus on CD105 and EPHA2 expressions.Methods:A retrospective case series study was conducted. A total of 74 patients with breast invasive ductal carcinoma in Affiliated Hospital of Jiangsu University from June 2019 to June 2024 were selected, and paraffin specimens from the patients after surgery were collected. Immunohistochemistry SP method was used to detect the expressions of CD105 and EPHA2 proteins in specimens. CD105 expression was expressed as the number of CD105 labeled microvessels, and EPHA2 expression was expressed as the proportion of EPHA2 positive expression area. The correlation of CD105 and EPHA2 expressions with the clinicopathological characteristics and diabetes mellitus of patients, as well as the relationship between the expressions of CD105 and EPHA2 were analyzed. Cox proportional hazards model was used to make univariate and multivariate analysis of the factors influencing overall survival of patients.Results:All 74 patients were female. The median age was 60 years old, 44 patients (59.46%) had tumor grade ≥ grade 3, 36 patients (48.65%) had tumor diameter ≥ 2 cm, 28 patients (37.84%) had lymph node metastasis, 30 patients (40.54%) had nerve vessel invasion, and 32 patients (43.24%) had diabetes mellitus. There were statistically significant differences in the proportion of patients with different age, tumor diameter, TNM stage, lymph node metastasis or not and nerve vessel invasion or not between diabetes mellitus group and non-diabetes mellitus group (all P < 0.05). The number of CD105 marking the microvessel was (32±9) and (24±8), respectively in diabetes mellitus group and non-diabetes mellitus group, and the difference was statistically significant ( t = 3.63, P < 0.010); the positive expression area proportion of EPHA2 was (19±5)% and (15±4)%, respectively, and the difference was statistically significant ( t = 3.85, P < 0.010). The expression of CD105 was related to the duration of diabetes mellitus, tumor diameter, TNM stage and lymph node metastasis or not (all P < 0.05), and the expression of EPHA2 was related to tumor diameter and TNM stage (all P < 0.05). Pearson correlation analysis showed a positive correlation between CD105 and EPHA2 expression ( r = 0.75, P < 0.001). The differences in overall survival of patients with or without diabetes mellitus and patients with different CD105 and EPHA2 expressions were statistically significant (all P < 0.05). Multivariate analysis showed that CD105 expression ( HR = 1.10, 95% CI: 1.04-1.16, P = 0.001) and EPHA2 expression ( HR = 1.35, 95% CI: 1.10-1.66, P = 0.005) were independent factors influencing the overall survival of patients with breast invasive ductal carcinoma. Conclusions:The expressions of CD105 and EPHA2 are independent prognostic factors in patients with breast invasive ductal carcinoma, and diabetes mellitus can promote the expressions of CD105 and EPHA2, which may increase the risk of poor prognosis.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To evaluate the efficacy and safety of treatments in phase Ⅰ oncology clinical trials in patients with advanced non-small-cell lung cancer(NSCLC).Methods:We retrospectively analyzed the clinical data of 65 patients with advanced NSCLC who received phase Ⅰ antitumor trial drugs at the Clinical Trial Research Center of The First Affiliated Hospital of Bengbu Medical University from January 2020 to December 2023.The efficacy and occurrence of serious adverse events(SAEs)were analyzed.Results:The objective response rate(ORR)and disease control rate(DCR)were 9.2%and 61.4%,respectively,whereas the median progression-free survival(PFS)and overall survival(OS)were 2.9 and 15.1 months,respectively.Previously receiving second-line or more lines of treatment and SAE occurrence were independent risk factors for a shorter PFS(P<0.05).A history of smoking and previous second-line or more lines of treatment were inde-pendent risk factors for a shorter OS(P<0.05).The SAE incidence was 15.4%,and no treatment-related deaths occurred.Conclusions:Treat-ments in phase Ⅰ oncology clinical trials are beneficial for patients with advanced NSCLC.Patients with a higher number of previous treat-ment lines and those who experienced SAEs during the trial had a shorter PFS,whereas patients with no smoking history and fewer previous treatment lines had a longer overall survival.The overall safety of the treatments was acceptable.

Objective:To introduce the clinical application of "page-turning" superior pancreatic lymph node dissection in laparoscopic D2 radical gastrectomy for gastric cancer.Methods:Patients who were confirmed to have adenocarcinoma by preoperative gastroscopy and pathological biopsy, with tumor staging evaluated by imaging as cT1~4aN0~3M0, without neoadjuvant therapy, and without absolute surgical contraindications, underwent laparoscopic radical gastrectomy for gastric cancer with "page-turning" superior pancreatic lymph node dissection. The "page-turning" superior pancreatic lymph node dissection was performed in four steps: (1) Expose the posterior gastric mesentery and dissect No.11p lymph nodes; (2) Expose the left gastric mesentery and dissect No.7, No.8a and No.9 lymph nodes; (3) Expose the right gastric mesentery and dissect No.5 lymph nodes; (4) Expose the left edge of the portal vein and dissect No.12a lymph nodes.Results:From April 2018 to October 2024, 112 patients with gastric cancer underwent laparoscopic D2 radical gastrectomy with "page-turning" superior pancreatic lymph node dissection, including 21 cases in the First Affiliated Hospital of Guangzhou University of Chinese Medicine, 78 cases in the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, and 13 cases in the Department of Gastrointestinal Surgery, Jilin Provincial People's Hospital. The TNM staging of all patients was as follows: 31 cases in stage Ⅰ, 24 cases in stage Ⅱ, and 57 cases in stage Ⅲ; 62 cases of differentiated adenocarcinoma and 50 cases of undifferentiated adenocarcinoma; the median length of tumors was 3.8 cm. All patients successfully completed the operation without conversion to open surgery, no intraoperative massive hemorrhage or postoperative death. The median total number of lymph nodes dissected in all patients was 32, and the median number of positive lymph nodes was 4.5. The overall postoperative complication rate was 5.4% (6/112), all of which were Clavien-Dindo grade Ⅱ, including pulmonary infection, pleural effusion, and incisional infection, all cured by symptomatic treatment. The median follow-up was 41.8 (2-78) months, with 7 cases lost to follow-up. During the follow-up period, 27 cases (25.7%) had tumor recurrence and 16 cases (15.2%) died.Conclusions:The "page-turning" superior pancreatic lymph node dissection technique is safe and feasible in laparoscopic radical gastrectomy for gastric cancer.
