Objective To analyze the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Shanxi Province from 2012 to 2024, and predict the incidence trend for 2025, and to provide a scientific basis for the formulation of prevention and control strategies. Methods Based on the surveillance data of HFMD in Shanxi Province from 2012 to 2024, the spatial and temporal distribution characteristics and time trends of the disease were analyzed. The ARIMA model was constructed and used to predict the incidence trend in 2025. Results From 2012 to 2024, a total of 254 028 HFMD cases were reported in Shanxi Province, with an average annual incidence rate of 54.17 per 100 000 population, a severe case rate of 0.56%, and a case fatality rate (CFR) of 12.60 per 100 000 population. Joinpoint regression analysis showed that the incidence rate, severe case rate, mortality rate, and case fatality rate all presented a downward trend. The epidemic exhibited obvious seasonal distribution characteristics, with the peak period from April to November, and two incidence peaks in June-July and October-November. The male-to-female incidence ratio was 1.41:1. Children aged 1-5 years accounted for 89.24% of the total cases, among which scattered children (58.48%) and nursery children (33.54%) were the high-risk groups. Linfen City (96.06 /100 000) and Taiyuan City (88.54 /100 000) had relatively high incidence rates. After 2017, the proportion of enterovirus A71 (EV-A71) decreased, while coxsackievirus A16 (Cox-A16) and other enteroviruses became the main epidemic strains. The ARIMA(1,0,1)(0,1,1)₁₂ model predicted that the incidence of HFMD in 2025 would remain at the level of 2023-2024, and the dual-peak characteristic would continue. Conclusion From 2012 to 2024, the overall HFMD epidemic in Shanxi Province generally shows a significant downward trend. The high-risk population includes scattered children and nursery children under 5 years old, with high-incidence areas concentrated in the central and southern regions, requiring focused attention. The seasonal ARIMA model can effectively fit the evolutionary trend of HFMD incidence in Shanxi Province and possesses short-term predictive capability.

Objective:To summarize the clinical characteristics, diagnosis and treatment experience of salivary pleomorphic adenoma in children. Methods:Thirty patients with salivary pleomorphic adenomas treated in Beijing Childrens Hospital from January 2008 to December 2022 were retrospectively reviewed, including 11 boys and 19 girls, with the age ranging from 0.3 to 14.4 years（median age 10.4 years）. Initial presentation, medical history, imaging workups, surgical approaches, complications, rates of recurrence were evaluated. Results:Major salivary gland lesions were most common（n=24, 80%）; 53.3%（16 of 30） arising in the submandibular glands and 26.7%（8 of 30） in the parotid. Minor salivary gland lesions（n=6, 20%） were removed from the palate, tongue, face, trachea, nasopharynx, and upper mediastinumand. Preoperative imaging was reviewed in all patients and consisted of 26 ultrasound exams, 2 computerized tomography（CT） exams, and 15 magnetic resonance imaging（MRI） exams. Fine needle aspiration biopsy was performed in 12 patients. Surgical excision was performed in all patients. Postoperative complications included transient facial paresis（n=3）, Pneumonia and pleural effusion（n=1）. Average length of follow-up was 36.7 months; confirmed recurrence occurred in one patients. Conclusion:The symptoms of salivary gland pleomorphic adenoma in children are different according to the location of the tumor. The treatment is complete surgical resection, and a small amount of normal tissue around the tumor should be removed to reduce recurrence.

Objective:To evaluate the effect and causality of serum metabolites on the pathogenesis of ulcerative colitis (UC), so as to provide reference for nutritional programs for patients with UC.Methods:Two-sample Mendelian randomization (MR) analysis was performed to estimate the causal relationship between serum metabolites and UC. Genome-wide association studies (GWAS) of 1 400 metabolites were performed, with the metabolites as exposure and UC as outcome. Inverse-variance weighted (IVW) was used to calculate causal estimates. Four other MR methods with different modeling assumptions including MR-Egger, weighted median, weighted mode, and simple mode were used as additional analyses to improve the stability of the results. The results were validated through heterogeneity and pleiotropy tests. Finally, the possible causal metabolites were analyzed by metabolic pathway analysis.Results:MR analysis revealed that 85 metabolites had a possible causal relationship with UC. Among them, phosphatidylglycerol 1,2-dipalmitoyl-gpc (DPPC) ( P=2.75×10 -6) and isovaleryl carnitine (C5) ( P=1.84×10 -5) were significant risk factors for UC. Metabolic pathway analysis identified 5 metabolic pathways that might be affected by these metabolites (all P<0.05), among which the porphyrin ( P=0.004) and pyrimidine metabolic pathways ( P=0.008) had higher confidence in impacting UC. Conclusions:There are causal relationships between some serum metabolites (in particular 1,2-dipalmitoyl-GPC and isovalerylcarnitine) and the risk of UC. The porphyrin and pyrimidine metabolic pathways may impact the pathogenesis of UC.

Objective:To analyze the treatment outcomes and prognoses of children with head and neck non-parameningeal rhabdomyosarcoma (HNnPM RMS).Methods:A retrospective analysis was performed on the clinical data of children with HNnPM RMS admitted to Beijing Children′s Hospital from September 2012 to September 2022. The clinical features, comprehensive treatment modes and prognoses of the patients were analyzed. The overall survival rate (OS) and event free survival rate (EFS) were calculated using the Kaplan-Meier method, and univariate analysis was performed using the Log-rank test.Results:A total of 70 children were included in this study, 38 males and 32 females, with a median age of 47 months (2-210 months). Pathological subtypes including the embryonal in 27 cases, the alveolar in 36 cases and the spindle cell and sclerosing in 7 cases. Thirty children (83.3%) with alveolar type were positive for FOXO1 gene fusion. All 70 children underwent chemotherapy, including 38 with neoadjuvant chemotherapy and 32 with adjuvant chemotherapy. Sixty of 70 children underwent surgery, of whom, 10 underwent two or more surgeries. There were 63 children underwent radiotherapy, including 54 with intensity-modulated radiation therapy, 4 with particle implantation and 5 with proton therapy. The median follow-up was 45 (5-113) months, the 5-year OS was 73.2%, and the 5-year EFS was 57.7%. Univariate analysis showed lymph node metastasis ( χ2=5.022, P=0.025), distant metastasis ( χ2=8.258, P=0.004), and high Intergroup Rhabdomyosarcoma Study (IRS) group ( χ2=9.859, P=0.029) as risk factors for poor prognosis. Before June 2016, the 5-year OS based on BCH-RMS-2006 scheme was 63.6%, and after 2016, the 5-year OS based on CCCG-RMS-2016 scheme was 79.6%. Conclusion:Multidisciplinary combined standardized treatment can offer good treatment outcome and prognosis for children with HNnPM RMS. Local control is a key to the efficacy of comprehensive treatment.

Objective:To develop the children′s postoperative health-related quality of life scale for thyroid cancer and to test its reliability and validity.Methods:The first draft of the scale was developed through literature search, focus group meetings, and a pre-survey, and 116 children (76 for testing and 40 for external validation) with thyroid cancer attending Beijing Children′s Hospital of Capital Medical University were selected to answer the scale, to screen and categorize the questions and to form the final scale with multiple dimensions.Results:The children′s postoperative health-related quality of life scale for thyroid cancer contained 5 dimensions and 29 questions. Exploratory factor analysis showed that the cumulative variance explained by the 5 factors was 64.343%. Confirmatory factor analysis showed correlations between the questions and dimensions of this scale, fair convergent validity for the scale, and good discriminant validity. The validity of the validity scale showed that there was a existing correlation between the questions and the validity scale of this scale. The item-dimension correlation coefficients showed that the questions in each dimension were well differentiated. The total Cronbach′s α coefficient of the scale was 0.930, the folded half reliability was 0.843, and retest reliabilities at 2 weeks, 1 month, and 3 months after the initial test were respectively 0.936, 0.922, and 0.910.Conclusion:The developed children′s postoperative health-related quality of life scale for thyroid cancer has good reliability and validity and can be used to assess the health-related quality of life of children after thyroid cancer surgery.

Objective:To examine the efficacy and experience of staged and segmented two hybrid surgeries for total repair of Debakey type Ⅰ aortic dissection (TIAD).Methods:This study was a retrospective case series. The clinic data of 10 patients with acute TIAD who were admitted to the Department of Cardiac Surgery, Second Hospital of Lanzhou University or the First People′s Hospital of Lanzhou, between January 2016 and August 2022, were retrospectively studied. Ten patients underwent hybrid surgeries in two hospitalizations (stages), including 7 males and 3 females with an age of (60±7) years (range: 49 to 71 years). In stage 1, the first type Ⅱ hybrid arch repair was performed to treat the ascending, total arch, and descending thoracic aorta for acute TIAD without circulatory arrest. In stage 2, the second hybrid surgery including infrarenal abdominal aorta replacement, visceral arteries bypass and endovascular thoracoabdominal aortic repair was performed to treat residual thoracoabdominal aortic dissection after the first hybrid operation (segmented). Basic data, preoperative concomitant diseases, high-risk factors, surgical approaches and postoperative complications of all important organs, as well as CT imaging were analyzed.Results:There was no death in the 20 hybrid surgical procedures. In stage 1 type Ⅱ hybrid surgery, 4 cases underwent reconstruction of the aortic sinutubular junction, while Bentall and David surgery was performed for 3 cases, respectively. A patient received coronary artery bypass grafting. Then all patients were sequentially treated with arch debranching and thoracic aortic endovascular repair. Postoperative complications included renal insufficiency (4/10), hemofiltration (1/10), hypoxemia (4/10), neurologic event (1/10) and type Ⅱ endoleak (1/10). Complete false lumen thrombosis occurred in 9/10 of the patients. All complications recovered successfully at discharge and the average hospital stay was (21±4) days (range: 16 to 28 days) in the first hospitalization. At stage 2, the second hybrid surgery was successfully performed in all patients. No paraplegia, hepatic or renal insufficiency, or endoleak occurred. However, branch graft embolism of the left renal artery was found in one patient 3 days after laparotomy, as well as of superior mesenteric artery in another. Superior mesenteric artery occlusion was successfully treated by endovascular recanalization. Complete false lumen thrombosis occurred in all patients. Although all patients had different degrees of intestinal dysfunction, they were gradually relieved at discharge, and the average hospital stay was (19±2)days (range:16 to 21 days) in the second hospitalization. During follow-up, CT angiography showed aortic remodeling in all patients.Conclusion:Staged and segmented two hybrid surgeries are safe and feasible for total repair of Debakey type Ⅰ aortic dissection and are associated with acceptable early and midterm outcomes.

Objective:To compare the effects of enhanced heat preservation strategies and conventional heat preservation strategies in the operation room on body temperature, coagulation function, and myocardial injury in patients with cervical spinal cord injuries.Methods:A retrospective cohort study was conducted to analyze the clinical data of 160 patients with cervical spinal cord injuries admitted to Second Affiliated Hospital of Xi′an Jiaotong University and Affiliated Honghui Hospital of Xi′an Jiaotong University from February to October 2022, including 82 males and 78 females, aged 38-64 years [(50.6±8.7)years]. Injured segments included C 3 in 19 patients, C 4 in 33, C 5 in 39, C 6 in 38, and C 7 in 31. According to American Spinal Injury Association (ASIA) classification, 10 patients were classified into grade A, 83 grade B, 39 grade C, and 28 grade D. All the patients underwent cervical laminoplasty, decompression and bone graft fusion surgery. According to different heat preservation strategies intraoperatively, the patients were divided into conventional heat preservation group ( n=80) and enhanced heat preservation group ( n=80). The body temperature changes before surgery, at 2 hours during surgery, immediately after surgery, at 2 and 24 hours after surgery were compared between the two groups. The changes of coagulation function before surgery and at 4 hours after surgery were compared between the two groups, including the prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT). The incidence of myocardial injury and the number of patients with myocardial injury measured by the indicators of cardiac troponin I (cTnI) and high-sensitivity cardiac troponin T (hs-cTnT) at 48 hours after surgery. Before surgery and at 14 days after surgery, ASIA classification was used to evaluate the neurological functions, including sensory and motor functions between the two groups. The incidence of cardiovascular events at 12 months after surgery were compared between the two groups. Results:A total of 145 patients were followed up for 12-18 months [(15.7±1.6)months]. At 12 months after operation, there were 7 patients in the enhanced heat preservation group were lost to follow-up, compared to 8 patients in the conventional heat preserration group. There was no statistically significant difference in body temperature between the two groups before surgery or at 24 hours after surgery ( P>0.05). At 2 hours during surgery, immediately after surgery and at 2 hours after surgery, the body temperature was (36.90±0.12)℃, (37.00±0.06)℃, and (37.16±0.06)℃ in the enhanced heat preservation group, which were significantly higher than those in the conventional heat preservation group [(36.56±0.03)℃, (36.74±0.08)℃, and (36.84±0.08)℃] ( P<0.01). The serum levels of PT, TT and APTT were not significantly different between the two groups before surgery ( P>0.05), while they were (13.1±1.2)seconds, (19.2±1.1)seconds, and (36.2±3.3)seconds in the enhanced heat preservation group at 4 hours after surgery, which were significantly lower than those in the conventional heat preservation group [(14.3±1.0)seconds, (20.2±1.1)seconds, and (38.7±3.4)seconds] ( P<0.01). The incidence of myocardial injury in the enhanced heat preservation group was 5.0% (4/80) at 48 hours after surgery, which was lower than 12.5% (12/80) in the conventional heat preservation group ( P<0.05). With cTnI as the indicator of myocardial injury, there were 2 patients [2.6%(2/76)] with myocardial injury in the enhanced heat preservation group, which was much lower than 8 patients [11.8%(8/68)] in the conventional heat preservation group ( P<0.05). With hs-cTnT as the indicator of myocardial injury, 8 patients [10.5%(8/76)] in the enhanced heat preservation group experienced myocardial injury, similar with 10 patients [14.7%(10/68)] in the conventional heat preservation group ( P>0.05). There were no statistically significant differences in the ASIA scores of the sensory and motor functions between the two groups before surgery and at 14 days after surgery ( P>0.05). The incidence of cardiovascular events at 12 months after surgery in the conventional heat preservation group was 27.8% (20/72), which was significantly higher than 9.6% (7/73) in the enhanced heat preservation group ( P<0.01). Conclusion:For patients with cervical spinal cord injuries, compared with conventional heat preservation strategies, the enhanced heat preservation strategies in the operating room can improve the patients′ core body temperature and coagulation function, and significantly reduce the incidence of myocardial injury and cardiovascular events.
