OBJECTIVE: To summarize the clinical and genetic characteristics of children with Silver-Russell syndrome (SRS) and improve the recognition of this disease. METHODS: A retrospective analysis was conducted on the clinical manifestations and genetic testing results of 29 children with SRS diagnosed at the Children's Hospital Affiliated to Zhengzhou University between March 2016 and June 2025. RESULTS: The 29 children had included 18 boys and 11 girls, with the age ranging from 2 months to 16 years. Their primary clinical manifestations included postnatal growth retardation (100%), small for gestational age (SGA) (100%), characteristic facial features (90%), limb asymmetry (83%), feeding difficulties (76%), ulnar deviation of the fifth finger (69%), body mass index (BMI) of < -2 SD (62%), and abnormal bone age (55%), including 15 cases with delayed bone age for an average of 1.5 years and 1 case with advanced bone age for 2.5 years. Additional manifestations included abnormal sexual development in 11 cases (38%), dental malocclusion in 11 cases (38%), allergic diseases in 10 cases (34%), cardiac diseases in 9 cases (31%), skeletal abnormalities in 7 cases (24%), renal hypoplasia in 5 cases (17%), and abnormal cranial MRI findings in 5 cases (17%). Twenty children were treated with recombinant human growth hormone (rhGH) at a dose of 0.1 ~ 0.15 U/(kg.d). Among them, 7 cases achieved annual height increase of ≥ 10 cm, 11 cases achieved annual height increase of ≥ 5 ~ 9 cm, and 2 cases achieved annual height increase < 5 cm. Twenty three children exhibited hypomethylation of imprinted genes in the chromosome region of 11p15, 4 presented maternal uniparental disomy of chromosome 7 [UPD(7)mat], and 2 had harbored nonsense variants of the HMGA2 gene. CONCLUSION SRS patients may present with diverse clinical manifestations including postnatal growth retardation, SGA, characteristic facial features, limb asymmetry, feeding difficulties, and ulnar deviation of the fifth finger. Most patients may exhibit abnormal methylation in the 11p15 region. rhGH therapy can improve the height of these patients.

Objective To explore the effectiveness of the generative large language model MedGo in nursing decision-making for elderly patients with multimorbidity. Methods A quasi-randomized controlled trial study was conducted involving 6 junior nurses, 6 senior nurses and the MedGo model from January 1, 2025 to March 31, 2025 at the Emergency Internal Medicine Ward of Shanghai East Hospital Affiliated to Tongji University. Clinical data of 120 elderly patients with multimorbidity were analyzed to compare the performance of the three groups in four tasks (nursing diagnosis assessment, nursing intervention formulation, complication identification, and complication prevention) from three evaluation dimensions: decision-making time consumption, decision accuracy, and decision-making quality. Results In terms of decision-making time, the senior nurse group completed all four tasks faster than the junior nurse group (P＜0.01), and the MedGo group completed all four tasks faster than the junior nurse group (P＜0.001) and the senior nurse group (P＜0.001). In terms of decision-making accuracy, senior nurse group scored higher than junior nurse group in all four tasks (P＜0.001), while the MedGo group outperformed the senior nurse group only in complication identification (P＜0.001). In terms of decision-making quality, the MedGo group scored higher than junior nurse group (P＜0.001) and senior nurse group (P＜0.001) in all four tasks. Conclusions The MedGo model demonstrates advantages of high efficiency, accuracy, and quality in nursing decision-making for elderly patients with multimorbidity; senior nurses outperform junior nurses in decision-making, providing diverse references for clinical nursing decision-making.

OBJECTIVE To investigate the clinical efficacy and safety of Zhengxintai granules as in the treatment of microvascular angina （MVA） following percutaneous coronary intervention （PCI） in patients with acute ST-segment elevation myocardial infarction （STEMI） and qi deficiency and blood stasis syndrome. METHODS Patients with STEMI and qi deficiency and blood stasis syndrome who underwent PCI and developed MVA and were admitted to the Jinan Fourth People’s Hospital （Jinan Cardiovascular Hospital） from March 2022 to March 2025 were selected， they were randomly divided into the control group and the observation group according to a random number table， with 76 cases in each group. Patients in the control group received conventional Western medicine treatment combined with a placebo， while patients in the observation group received Zhengxintai granules （5 mg per dose， three times daily， for 8 weeks） in addition to conventional Western medicine treatment. The clinical efficacy [including the total effective rate of traditional Chinese medicine （TCM） syndrome improvement and the total effective rates of Western clinical efficacy] was compared between the two groups. The following indicators were detected before and after treatment： TCM syndrome scores， angina pectoris episodes [daily attack frequency， duration per attack， Visual Analogue Scale （VAS） score]， cardiac function indicators [lactate dehydrogenase （LDH）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， left ventricular end-diastolic dimension （LVEDD）， left ventricular end-systolic dimension （LVESD）， left ventricular ejection fraction （LVEF）， cardiac output （CO）， fractional shortening （FS）]， coagulation function indicators [thrombin time （TT）， prothrombin time （PT）， fibrinogen （FIB）]， fibrinolytic marker （D-dimer）， vascular endothelial function indicators [vascular endothelial growth factor （VEGF）， nitric oxide （NO）， endothelin-1 （ET-1）] and myocardial microcirculation hemodynamic indicators [end-diastolic velocity （EDV）， peak systolic velocity （PSV）， resistance index （RI）， pulsatility index （PI）]. The quality of life [Seattle Angina Questionnaire （SAQ） score] and the incidence of adverse reactions were also compared between the two groups. RESULTS There was no patient dropout during the entire course of the study. The total effective rates of improvement in TCM syndromes and the total effective rates of Western clinical efficacy in the observation group were significantly higher than those in the control group （93.42% vs. 82.89%， 94.74% vs. 84.21%， P＜0.05）. Before the treatment， the comparison of each examination indicator between the two groups showed no statistically significant differences （P＞0.05）. Compared with before treatment， the TCM syndrome scores， the number of daily angina pectoris attacks and the duration of each attack， the VAS scores， LDH， NT-proBNP， FIB， D-dimer， ET-1 levels， LVEDD， LVESD， RI and PI after treatment in both groups were significantly reduced， shortened or decreased （P＜0.05）； VEGF and NO levels， LVEF， CO， FS， TT， PT， EDV， PSV， and the standard scores of five dimensions including angina pectoris stability， as well as the total scores of SAQ， all significantly increased or prolonged （P＜0.05）. Furthermore， the improvements in the aforementioned indicators （except for LVEF） in the observation group were significantly greater than those in the control group （P＜0.05）. There was no statistically significant difference in the total incidence of adverse reactions between the two groups （P＞0.05）. CONCLUSIONS Zhengxintai granules， when used as an adjunct to conventional Western medicine， can significantly alleviate the related symptoms of MVA in STEMI patients with qi deficiency and blood stasis syndrome after PCI， repair damaged cardiac function， restore the balance of the coagulation-fibrinolysis system， improve vascular endothelial function and myocardial microcirculation perfusion， and significantly enhance the quality of life of patients

Objective: To evaluate oral health status and knowledge, attitude and practice (KAP) among third grade primary school students after the implementation of the Comprehensive Intervention Project for Childhood Oral Diseases in Guizhou Province, so as to provide evidence for program optimization. Methods: Using a multistage cluster sampling method, oral examinations and questionnaire surveys were conducted among third grade primary school students in schools covered by the Comprehensive Intervention Project for Childhood Oral Diseases in Guizhou Province (intervention group, n =1 030) and schools not covered by the program (control group， n =1 130) in November 2023. A follow up survey was conducted one year after the project s implementation (December 2024) to evaluate the differences in oral health status and KAP between the two groups. The t-test and χ 2 test were used to compare means and rates, respectively. Results: One year after implementation, the permanent caries prevalence, caries filling ratio, mean dmft/DMFT, and mean simplified debris index in the intervention group were 33.3%, 22.3 %, 3.44±3.10, 0.77±0.56, which were all better than those in the control group (39.8%, 17.3%, 3.89±2.85, and 0.87± 0.63 ) ( χ 2/ t =9.87, 8.78, -2.59, -3.91,all P <0.05). After intervention, the levels of oral health knowledge, attitude and behaviors in the intervention group were better than those in the control group ( Z =7.69, 2.35, 2.10, all P <0.05). Except for the item "fluoride has no protective effect on teeth", the correct response rates of other oral health knowledge items in the intervention group were higher than those in the control group ( χ 2=3.92-163.94, all P <0.05). The reported rates of tooth brushing related behaviors and sugary beverage consumption were higher in the intervention group than in the control group ( χ 2=4.02-11.42，all P <0.05). Conclusions The Comprehensive Intervention Project for Childhood Oral Diseases improves children s oral health status, oral health knowledge, and some oral health behaviors, but has limited effects on some behaviors and oral health attitudes. Future efforts should focus on the factors influencing the transformation of children s oral health attitudes and behaviors, along with strengthening long term follow up evaluations.

OBJECTIVE: To construct a predictive model for the reduction in methadone maintenance treatment (MMT) and evaluate the effects of different interventions and other clinical factors on methadone reduction using Shapley additive explanations (SHAP). METHODS: Two clinical trials of acupuncture for methadone reduction in MMT patients were analyzed, and the baseline data, MMT related information, intervention measures, the data related to dose-reduction outcomes were collected. The predictive model was constructed by means of 6 machine learning algorithms including support vector machine (SVM), K-nearest neighbors (KNN), logistic regression (LR), Naive Bayes (NB), random forest (RF) and categorical-boosting (CatBoost), and 2 integration methods, blending-ensemble method (Blending) and Stacking-ensemble method (Stacking). SHAP was employed for the interpretability analysis of the optimal model. RESULTS: A total of 251 MMT patients were included, 128 cases in the acupuncture group and 123 cases in the non-acupuncture group. CatBoost and Stacking performed optimally in the test set. CatBoost obtained an accuracy of 0.780 0±0.060 8, a precision of 0.500 0±0.120 0, a recall of 0.818 2±0.140 2, F1 score of 0.620 7±0.114 0, and receiver operating characteristic-area under curve (ROC-AUC) of 0.857 8±0.140 2 for the subjects. In MMT patients with acupuncture as an adjunctive therapy, the top 5 important features for methadone reduction, included intervention measures, body mass index (BMI), the duration of MMT, the history of opioid use and occupation; and SHAP values were 1.25, 0.36, 0.21, 0.19 and 0.12, respectively. The SHAP feature dependence plot showed that BMI, MMT duration and the history of opioid use presented a nonlinear negative correlation with the reduction effect. CONCLUSION In acupuncture as adjunctive therapy for methadone reduction, the clinical factors should be considered comprehensively; and the interpretable predictive model provides a scientific basis for it, which is conducive to the improvement of clinical strategy of acupuncture for methadone reduction and the development of personalized reduction scheme.

BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

BACKGROUND: Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events. METHOD: A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM_2.5), SO₂, NO₂, CO, and O₃ from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality. RESULTS: We found MACE mortality was significantly associated with PM_2.5 (relative percent increase 2.91% per 10 µg/m³ increase, 95% CI 1.32-4.53), NO₂ (5.37% per 10 µg/m³ increase, 95% CI 1.56-9.33), SO₂ (6.82% per 10 µg/m³ increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m³ increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO₂ and SO₂ exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM_2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO₂. CONCLUSIONS The study results showed that short-term exposure to ambient PM_2.5, NO₂, SO₂, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

Objective To explore the utility of comprehensive geriatric assessment (CGA) in screening risk factors for osteosarcopenia (OS) among older adults (≥80 years old) and to evaluate the therapeutic efficacy of CGA-guided integrated interventions for OS. Methods A total of 420 patients aged ≥80 years, recruited from the Department of Geriatrics, General Practice of The Affiliated Jiangyin Hospital of Nantong University, and community health centers from January 2022 to October 2024, were enrolled. Participants were classified into OS (n＝139) and non-OS (n＝281) groups based on diagnostic criteria. CGA was utilized to compare differences in general characteristics, laboratory indicators, comorbidities between groups. Binary logistic regression analysis identified independent risk and protective factors. Subsequently, 40 OS patients were randomly assigned to an intervention group (n＝20) receiving integrated interventions including nutritional support, exercise training, and psychological management or a control group (n＝20, receiving routine care). Appendicular skeletal muscle mass index (ASMI), grip strength, gait speed, and bone mineral density (BMD) T-score were compared between groups after 3 months. Results The prevalence of OS in this cohort was 33.1%. Compared to the non-OS group, the OS group exhibited significant differences in age, body mass index (BMI), smoking history, comorbidity index, concomitant medication, cognitive impairment, visual and hearing impairment, sleep disorders, depression, marital status, social participation, activities of daily living, nutritional risk, total cholesterol, uric acid, and constipation (P＜0.05). Logistic regression analysis identified age and comorbidity index as significant risk factors for OS, while BMI, married status, total cholesterol, and activities of daily living (assisted and independent) served as protective factors. The intervention group demonstrated significant improvements in grip strength, gait speed, BMD T-score, and male ASMI compared to controls (P＜0.05). Conclusions CGA demonstrates clinical utility in systematically identifying risk factors for OS in the old population. Multimodal interventions guided by CGA effectively improve musculoskeletal function in elderly OS patients.

Objective: To investigate the prevalence and influencing factors of mild cognitive impairment (MCI) among middle-aged and elderly people in Xihu District, Hangzhou City, so as to provide insights into prevention and intervention of MCI among middle-aged and elderly people. Methods: People aged 55 years and above were sampled from Xihu District using the multi-stage random sampling method, and demographic information, lifestyle behaviors, and chronic disease were collected through questionnaire surveys. The prevalence of MCI was assessed using the Montreal Cognitive Assessment, and influencing factors for MCI were analyzed using a multivariable logistic regression model. Results: A total of 440 valid questionnaires were recovered, with an effective recovery rate of 97.78%. There were 190 males (43.18%) and 250 females (56.82%). There were 179 respondents at ages of 55 to <65 years, accounting for 40.68%. The prevalence of MCI was 18.64%. Multivariable logistic regression analysis showed that the risk of MCI was higher among the middle-aged and elderly people who were aged 65 to 95 years (55 to <65 years as the reference, 65 to <75 years, OR=4.156, 95%CI: 1.284-13.201; 75 to 95 years, OR=5.013, 95%CI: 1.752-14.126), were smokers (OR=4.768, 95%CI: 1.560-14.580), had higher daily cooking oil intake (OR=2.128, 95%CI: 1.062-4.199), had diabetes (OR=4.137, 95%CI: 1.144-4.958) and had hypertension (OR=8.093, 95%CI: 1.697-38.593); while the risk of MCI was lower among the middle-aged and elderly people who were engaged in mental labor (OR=0.074, 95%CI: 0.007-0.756) and had a monthly household income per capita of 4 000 yuan and above (4 000 to <8 000 yuan, OR=0.071, 95%CI: 0.014-0.358; 8 000 yuan and above, OR=0.009, 95%CI: 0.001-0.136). Conclusion MCI among middle-aged and elderly people in Xihu District is affected by age, occupation, monthly household income per capita, smoking, daily cooking oil intake, diabetes and hypertension.
