Objective To explore the clinical characteristics of patients with heat illness and the related factors for progression to heatstroke so as to provide a basis for early clinical intervention.Methods A case-control study design was adopted.A total of 164 patients with heat illness admitted to a hospital in Hainan Province from January 2018 to December 2023 were included,and divided into a heatstroke group(21 cases)and a non-heatstroke group(143 cases).Univariate and multivariate logistic regression analyses were used to evaluate the associations of body temperature,heart rate and mean arterial pressure at admission with the progression to heatstroke.Results The incidence of organ dysfunction in the patients with heat illness was 45.12％(74/164),and 12.80％(21/164)progressed to heatstroke.Multivariate logistic regression analysis showed that at admission,body temperature＞40 ℃(OR=10.11,95％CI:2.86～35.78),heart rate＞100 beats/min(OR=9.07,95％CI:2.75～29.94),and mean arterial pressure＜70 mmHg(OR=9.05,95％CI:2.75～29.75)were the related factors affecting the progression of heat illness patients to heatstroke.Conclusion The incidence of organ dysfunction in heat illness patients is relatively high.Body temperature,heart rate and mean arterial pressure at admission may be the related factors for predicting the progression of heat illness to heatstroke.

Autism spectrum disorder（ASD）is a multifactorial，pervasive neurodevelopmental disorder.As the morbidity rate of ASD in children increases year by year，feeding and eating behaviors，as an important and common clinical problem in children with ASD，are gaining more and more attention.Many children with ASD often have food selection issues，chewing problems，food allergy and related gastrointestinal symptoms，and even serious diseases such as eating disorders，which negatively impact on their growth and development.There are many factors affecting feeding and eating behavior problems in children with ASD，such as sensory processing，ritualistic eating behavior，gastrointestinal symptoms，age，and parenting pressure.There are also a variety of interventions that can help to improve feeding and eating behavior problems in children with ASD.Strengthening the understanding of these influencing factors and intervention treatment methods is beneficial for improving the quality of life in children with ASD.

As one of the core theories of spleen governing transportation and transformation in the traditional Chinese medicine visceral manifestation theory,the modern biological basis of"spleen qi disperses essence"has not been fully elucidated.Lipids are one of the three major nutrients in the body,which are derived from exogenous absorption or endogenous transformation,and belong to the category of"grease"and"essence"substances in traditional Chinese medicine.Because of their hydrophobic nature,lipids require apolipoproteins to be transported in the bloodstream and used by the body;similarly,essence also needs spleen qi transformation to be distributed throughout the body and exert their nourishing effects,revealing a certain degree of inherent unity between the two.When the spleen qi functions properly,essence dispersal is orderly and lipid metabolism remains in homeostatic balance;if spleen deficient leads to impaired transportation,the essence will not be distributed,and the lipid turbidity will accumulate,causing disease.Classic strengthening spleen prescriptions such as Zexie Decoction,can reshape lipid homeostasis by regulating apolipoproteins.Based on apolipoprotein-mediated lipid metabolism,this paper explores the modern molecular biology basis of the theory of"spleen qi disperses essence,"which provides novel insights for enriching the modern research of traditional Chinese medicine visceral manifestation theory,and lays the foundation for clinical practice and theoretical innovation in the treatment of metabolic diseases from the spleen.

Objective:To investigate the role and mechanism of TrxR1 in reprogramming tumor-associated macrophage in breast cancer,providing novel insights and theoretical foundations for clinical breast cancer treatment.Methods:TISIDB database was used to analyze the relationship between TXNRD1(encoding TrxR1)and tumor immunity.Mouse breast cancer 4T1 cells conditioned medium was collected and co-cultured with bone marrow-derived macrophage(BMDM)cells for 48 h to detect the expression of macrophage immunosuppression-related factors.TrxR1 secretion by tumor cells was measured using ELISA kits.TXNRD1 knockdown efficiency was verified via Western blot.Fluorescence quantitative PCR(qPCR)and flow cytometry were used to detect the expression levels of macrophage immunosuppressive factors after TXNRD1 knockdown in tumor cells.JASPAR database was used to analyze the potential regulatory factors,and Western blot was used to verify the expression of pathway-related proteins.Results:Database analysis found that TXNRD1 expression positively correlated with survival risk indices across multiple cancers,with the strongest association observed in breast cancer.Further analysis found that elevated TXNRD1 expression correlated with reduced infiltration of M1 macrophages and natural killer(NK)cells,but increased M2 macrophage infiltration.qPCR and flow cytometry demonstrated that tumor-conditioned medium enhanced macrophage immunosuppression,whereas medium from TXNRD1-knockdown tumor cells suppressed this effect.And TrxR1-neutralizing antibodies could also reversed this effect.JASPAR database analysis identified STAT3 and STAT6 as potential transcriptional regulators,and Western blot confirmed that TXNRD1-knockdown tumor cells conditioned medium inhibited STAT6 pathway activation in macrophages.Conclusion:In the tumor microenvironment,breast tumor-derived TrxR1 promotes macrophage immunosuppression,potentially through activation of the STAT6 signaling pathway.

Objective:To evaluate the clinical equivalence between a domestic calcipotriol/betamethasone dipropionate ointment and the originator product in the treatment of stable plaque psoriasis.Methods:A multicenter, randomized, double-blind, three-arm, parallel-group, active- and placebo-controlled study was conducted, and 449 patients aged 18 - 65 years with stable plaque psoriasis were enrolled from 25 hospitals (such as the First Affiliated Hospital of China Medical University). Eligible patients had a baseline physician's global assessment (PGA) score of ≥ 3 points, baseline body surface area (BSA) involvement of 5% - 30%, and a target lesion psoriasis area and severity index (TL-PASI) for plaque elevation of ≥ 3 points. Participants were randomly assigned in a 2:2:1 ratio to the test group ( n = 179), reference group ( n = 180), and placebo group ( n = 90), and applied the domestic calcipotriol/betamethasone dipropionate ointment, originator product, and ointment base respectively, once daily in the evening for 4 weeks. Efficacy and safety were assessed at weeks 1, 2, and 4. The primary efficacy endpoints were the treatment success rates and clinical success rates in each group at week 4. The per-protocol set (PPS) was used for the primary efficacy analysis, and the intention-to-treat (ITT) set for supplementary efficacy analysis. Equivalence between the test and reference preparations was tested using the Cochran-Mantel-Haenszel method adjusted for randomization strata. Superiority of the test and reference preparations over the placebo was also tested. Measurement data were compared among the 3 groups using analysis of variance or non-parametric tests, while treatment success rates, clinical success rates, and incidence rates of adverse reactions were compared using the chi-square test. Results:The ITT, PPS, and safety sets included 447, 420, and 448 patients, respectively. In the ITT set, patients were aged 43.6 ± 12.8 years, including 320 (71.6%) males and 127 (28.4%) females, and the disease duration was 11.21 ± 9.05 years; 316 (70.7%) had a PGA score of 3 points and 131 (29.3%) had a PGA score of 4 - 5 points. No significant differences in the baseline characteristics (including age, sex, disease duration and disease severity) were observed among the 3 groups (all P > 0.05). Based on the PPS analysis, the treatment success rates were 57.9% (99/171) in the test group, 50.3% (86/171) in the reference group, and 7.7% (6/78) in the placebo group, and the clinical success rates were 57.9% (99/171), 50.3% (86/171), and 10.3% (8/78), respectively; both the test and reference groups were superior to the placebo group in both treatment and clinical success rates (all P < 0.001) ; the rate differences for treatment success (90% confidence interval [ CI]: -1.3% - 16.4%) and clinical success (90% CI: -1.3% - 16.3%) between the test and reference groups were entirely within the pre-defined equivalence margin (-20% - 20%). Subgroup analyses by baseline PGA scores: for patients with a baseline PGA score of 3 points, the treatment success rates in the test, reference, and placebo groups were 60.8% (73/120), 52.1% (62/119), and 11.1% (6/54), respectively, and the corresponding clinical success rates were 61.7% (74/120), 53.8% (64/119), and 13% (7/54), respectively; the test and reference groups did not differ significantly in treatment or clinical success rates (both P > 0.05), but both showed higher success rates than the placebo group (all P < 0.001) ; the results of statistical comparisons among the 3 groups in patients with a baseline PGA score of 4 - 5 points were consistent with those observed in patients with a baseline PGA score of 3 points. The percentage reductions in PGA and TL-PASI scores from baseline to weeks 1, 2, and 4 showed significant differences among the 3 groups, which were significantly higher in the test and reference groups than in the placebo group (all P < 0.001), but did not differ between the test and reference groups (all P > 0.05). The primary adverse reactions were local skin reactions, such as pruritus, pain, and erythema. The incidence rates of adverse reactions were 8.9% (16/179) in the test group, 7.3% (13/179) in the reference group, and 7.8% (7/90) in the placebo group, with no significant difference among the 3 groups ( P > 0.05) . Conclusions:The domestic calcipotriol/betamethasone dipropionate ointment demonstrated clinical equivalence to the originator product in the treatment of stable plaque psoriasis, and the two agents exhibited comparable efficacy for patients with varying degrees of disease severity, and were comparable in the speed and degree of clinical improvement, with similar favorable safety profiles.

Objective:To develop and validate clinical predictive models for identifying poor short-term response to recombinant human growth hormone(rhGH) treatment in children with short stature.Methods:A retrospective analysis was conducted on 118 children diagnosed with growth hormone deficiency or idiopathic short stature who were treated at the First Affiliated Hospital of Zhengzhou University and two other hospitals between January 1, 2020, and January 1, 2024. A poor response to rhGH was defined as a height increase of less than 0.2 standard deviation score(SDS) after 6 months of rhGH treatment. LASSO regression was used to identify predictive variables from baseline and follow-up data. Two logistic regression models were conducted: Model A(incorporating baseline variables only) and model B(incorporating both baseline and follow-up variables), and nomograms were created for visualization. External data and internal resampling were used for dual validation of the models, and their performance was compared.Results:A total of 118 children with short stature were included. Six baseline predictive variables(diagnosis, initial height SDS, bone age, bone age-chronological age difference, rhGH dose, and gender) and one follow-up variable(height SDS after 3 months of rhGH treatment) were identified. Area under the curve values for Model A and Model B were 0.753(95% CI 0.696-0.811) and 0.930(95% CI 0.891-0.975), respectively. Calibration curves, decision curve analysis, and other evaluation metrics demonstrated good discrimination and clinical utility for both models. Model B, incorporating the 3-month follow-up variable, showed superior predictive performance compared to Model A. Conclusions:The clinical prediction models developed in this study(Model A and Model B) are practical and reliable tools for quantitatively, conveniently, and intuitively identifying children with short stature at risk of poor response to rhGH treatment.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To assess the nutritional status and risk of children with cyclic vomiting syndrome（CVS）and to provide a clinical evidence for nutritional support.Methods:A total of 160 children diagnosed with CVS and 160 healthy controls were prospectively enrolled in the study，who were admitted to Beijing Tsinghua Changgung Hospital from April 2021 to February 2024.Nutritional status was assessed by anthropometric indices（height，weight，and body mass index），and it was expressed in standard deviation score（Z score）.Nutritional risk screening tool STRONGkids was applied to nutritional risk screening，and the laboratory assessment（albumin，pre-albumin，hemoglobin，urea nitrogen and creatinine）were measured.Results:Among the 160 cases，there were 73 males and 87 females，including 18 cases of mild seizures and 142 cases of moderate and severe seizures，with the average onset age of（47.54±2.96）months and an average diagnosis age of（74.89±3.68）months.The average duration from the first attack to diagnosis was（27.35±2.36）months，and the average course of the disease was（41.35±2.63）months.The malnutrition rate of children in CVS was 36.9%（59/160），of which 18.1%（29/160）was severely malnourished.There was a statistically significant difference in the weight-for-age Z-score（WAZ），height-for-age Z-score（HAZ），and body mass index-for-age Z-score（BAZ）between the CVS group and the control group（ P<0.001）.We found a statistically significant difference in laboratory indicators（albumin，pre-albumin，hemoglobin，urea nitrogen and creatinine）between the two groups（all P<0.001）and hemoglobin was positively correlated with WAZ，HAZ and BAZ（ r=0.346,0.250,0.277，all P<0.01）.Using the STRONGkids nutritional risk screening tool，there were 43 cases with moderate nutritional risk and 117 cases with high nutritional risk，and children with high nutritional risk were likely to have lower WAZ，HAZ and BAZ than the children with moderate nutritional risk，and there was a significant difference in WAZ，HAZ，BAZ，hemoglobin，and creatinine between the two groups（ P<0.05）.And there was a correlation between the degree of CVS attack and nutritional risk grouping（ r=0.543， P<0.001）. Conclusion:Children with CVS have a high incidence of malnutrition，and the serum albumin，prealbumin，hemoglobin，urea nitrogen and creatinine levels are of great value for nutritional assessment.The STRONGkids score method helps to evaluate nutritional risk in children with CVS.

Objective:To investigate the characteristics of gut microbiota distribution in children with cyclic vomiting syndrome（CVS）complicated by constipation.Methods:The children with CVS, aged from 1 to 16 years, who were admitted to Beijing Tsinghua Changgung Hospital from June 2022 to January 2024, were divided into constipation group and normal group(non-constipation group) according to whether they were complicated with constipation or not.The clinical data and stool samples of children were collect. The abundance, diversity and composition of intestinal flora in fecal samples of two groups were detected by metagenomics sequencing.Results:A total of 20 children with CVS were collected, including 10 patients in constipation group and 10 patients in normal group.There were no significant differences in general demographic data between the two groups, including age at admission, age at first onset, body mass index, gender distribution, disease severity, endoscopic findings, and abdominal pain patterns.Microbiome analysis yielded 470 operational taxonomic units (OTUs), with 414 OTUs identified in normal group and 56 OTUs in constipation group. The abundance and diversity of intestinal flora in constipation group were significantly lower than those in normal group. Principal coordinate analysis and principal component analysis indicated significant structural differences in gut microbiota composition between the two groups. LEfSe analysis revealed distinct taxonomic patterns between the two groups, with the normal group demonstrating predominant representation of Firmicutes at the phylum level, while the constipation group showed higher relative abundance of Bacteroidetes and Actinobacteria. KEGG pathway analysis revealed that the carbon metabolism pathways was significantly enriched in the constipation group.Conclusion:There are significant differences in intestinal flora between CVS children with and without comorbid constipation.Bacteroides and Actinomycetes play an important role in constipation of children with CVS. The diversity and metabolic function of intestinal flora may be one of the pathological mechanisms of CVS complicated with constipation.

Objectives:To explore the predictive value of residual Murray's law-based quantitative flow ratio(μQFR)on long-term vessel-oriented composite endpoints(VoCE).Methods:This retrospective study included 3 510 patients from the FAVOR Ⅲ China trial.Offline residual μQFR analysis was performed on all vessels(diameter≥2.5 mm)with 50%-90%stenotic lesions.Patients were stratified into high-,intermediate-,and low-risk groups based on residual μQFR tertiles.The primary endpoint was 3-year VoCE,defined as a composite of cardiac death related to the target vessel,target vessel-related spontaneous myocardial infarction,and ischemia-driven target vessel revascularization.Results:Offline analysis was performed on 5 256 vessels from 3 510 patients.The mean residual μQFR was 0.92±0.75.The high-risk group(residual μQFR≤0.91)with 1 554 patients(1 958 vessels);the intermediate-risk group(residual μQFR 0.92-0.96)with 1 211 patients(1 906 vessels);and the low-risk group(residual μQFR>0.96)with 745 patients(1 392 vessels).Over 3-year follow-up,VoCE occurred in 227 vessels(4.3%).The 3-year VoCE incidence was significantly higher in the high-risk group compared to the intermediate-and low-risk groups(6.2%vs.4.1%vs.2.5%,log-rank P<0.001),primarily driven by ischemia-driven target vessel revascularization(5.0%vs.3.0%vs.1.6%,log-rank P<0.001).Hypertension(OR=0.83,95%CI:0.72-0.96),hypercholesterolemia(OR=0.84,95%CI:0.73-0.97),bifurcation lesions(OR=0.72,95%CI:0.63-0.83),moderate/severe calcification(OR=0.70,95%CI:0.57-0.84),and tandem lesions(OR=0.59,95%CI:0.47-0.75)were independent predictors of lower residual μQFR values.Conclusions:Lower residual μQFR is significantly associated with increased VoCE risk during the 3-year follow up period.
