Objective:To investigate the diagnostic features of eosinophilic gastroenteritis (EGE) of the stomach and duodenum.Methods:A case-control study was conducted to retrospectively analyze 238 biopsy specimens of gastric and duodenal EGE (75 cases) and 133 biopsy specimens of chronic active gastroenteritis (97 cases) in Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, Beijing, China from 2012 to 2023. The eosinophil count, infiltration site and other pathological features (e.g., infiltration of neutrophils into the epithelium, edema, and increase of background lymphocytes and plasma cells) were examined under a microscope. Chi-square test, chi-square multiple comparison ( Bonferroni method) and modified Poisson regression were used to analyze the data. Results:The results showed that there were significant differences in eosinophil count ( χ2=43.926, P<0.01), location ( χ2=31.391, P<0.01), neutrophilic infiltration of the epithelium ( χ2=5.199, P=0.023), edema ( χ2=3.934, P=0.047), and lymphoplasmacytosis ( χ2=36.813, P<0.01) between the EGE and control cases. The results of Chi-square multiple comparisons showed that eosinophils distributed in clusters or sheets (versus other grades of eosinophil presence) were statistically associated with EGE. When eosinophils infiltrated the epithelium (versus eosinophils in other locations of the mucosa), there was a statistically significant association with EGE. Modified Poisson regression also showed that EGE was more likely to have eosinophilic infiltration of epithelium [ RR=1.661, P=0.001,95% CI (1.397,1.973)] and that of muscularis mucosa [ RR=1.818, P<0.01,95% CI (1.491,2.216)]. Conclusions:The important pathological features for diagnosing EGE of the stomach and duodenum are that eosinophils are clustered or distributed in sheets with epithelial infiltration. However, epithelial infiltration by neutrophils, edema and background lymphoplasmacytosis are relatively rare.

Objectives:To retrospectively analyze the preoperative imaging and echocardiographic data of pa-tients with thoracic lordosis,and to investigate the relationship between thoracic lordosis and the cardiac structure and function by comparing with normal people.Methods:The imaging and echocardiographic data of patients with thoracic lordosis and normal people obtained between January 2013 and December 2023 were collected and analyzed.According to thoracic angle,the patients were divided into group A of 27 cases[tho-racic lordosis(TL)group,T5-T12≤0°]and group B of 29 cases[red uced thoracic kyphotic(TK)group,0°＜T5-T12≤20°].A control group of 29 normal people was set up as group C(normal group,20°＜T5-T 12 ≤ 40°).General clinical data including gender,age,height,weight,body mass index(BMI),body surface area(BSA),imaging parameters on X-ray films such as thoracic sagittal and coronal Cobb angles,imaging findings on CT such as spinal penetration index volume(SPIV)and cardiac volume ratio in apical vertebra region(CVRA)were collected,as well as the echocardiographic parameters including left ventricular end-diastolic diameter(LVDd),right ventricular end-diastolic diameter(RVDd),left atrial diameter(LAD),right atrial diameter(RAD),right ven-tricular outflow tract(RVOT),aortic diameter(AO),ascending aortic diameter(AAO),main pulmonary artery diam-eter(MPA),end-diastolic interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),ejection fraction(EF),fraction shortening(FS),stroke volume(SV),cardiac output(CO),cardiac index(CI),systolic pulmonary artery pressure(SPAP).Statistical analysis was conducted using SPSS 25.0 software for data comparison and correlation analysis between the three groups.Results:SPIV was negatively correlated with sagittal Cobb angle and not correlated with coronal Cobb angle;SPIV was negatively correlated with LVDd,RVDd,LAD,RAD,RVOT,AO,AAO,MPA,IVST,and LVPWT;SPIV wasn't correlated with EF,FS,SV,CO,CI,and SPAP;CVRA was negatively correlated with sagittal Cobb angle and not correlated with coronal Cobb angle;CVRA was negatively correlated with RVDd,IVST,and LVPWT;There was no correla-tion between CVRA and LVDd,LAD,RAD,RVOT,AO,AAO,MPA;CVRA wasn't correlated with EF,FS,SV,CO,CI,and SPAP.Conclusions:SPIV can more effectively reflect the impact of thoracic lordosis on cardiac structure and function than CVRA,and a reduction in thoracic kyphosis angle may exacerbate the workload on cardiac blood vessels.During the orthopedic surgery for patients with thoracic lordosis,significant changes may occur in the structural and functional parameters of the thoracic cavity and cardiac chambers due to factors such as general anesthesia,prone positioning,compression of the sternum and thoracic cage,and muscle relaxant administration,therefore particular attention should be paid to the risks of airway ob-struction and hemodynamic instability.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Radiomics can provide a large number of features derived from medical images, which can be correlated with certain biological characteristics and clinical endpoints. Delta radiomics enables the analysis of feature changes across different acquisition time points, typically before and after treatment. Compared with traditional radiomics, delta radiomics allows the evaluation of changes in radiomic features at different time points to better guide clinical diagnosis and treatment, thereby facilitating the development of personalized treatment plans for patients. Delta radiomics offers certain advantages in the differential diagnosis, prognosis prediction, treatment response assessment, and side effect evaluation of oncological diseases. This article reviews the applications of delta radiomics in the diagnosis and treatment of head and neck tumors, lung cancer, gastrointestinal tumors, pancreatic cancer, prostate cancer, breast cancer, and soft tissue tumors.

ObjectiveTo clarify whether epigallocatechin gallate （EGCG） is involved in the clearance of amyloid β-protein （Aβ） and autophagy induction by microglia， so as to explore the potential mechanisms of EGCG in the prevention and treatment of Alzheimer's disease （AD）. MethodsSix-month-old APP/PS1 mice were randomly divided into model and EGCG groups， with some additional wild type （WT） mice as the control group， each group consisting of 15 mice. The EGCG group received continuous gavage administration［5 mg/（kg·d）］ for 8 weeks， followed by the open field test and Y-maze to assess the learning and memory abilities of the mice. Thioflavin-S staining was used to evaluate the content and distribution of amyloid β-protein （Aβ）in the brain parenchyma of the mice， and immunofluorescence was employed to detect the expression levels of Aβ_1-42， glial fibrillary acidic protein （GFAP）， and ionized calcium-binding adapter molecule 1 （Iba1） in the hippocampal tissue of the mice. Additionally， N9 mouse microglial cells were induced with 20 µmol/L Aβ_1-42， and the cell viability was measured after treatment with different concentrations of EGCG （5 µmol/L， 10 µmol/L， 20 µmol/L）. Western blotting was used to detect the levels of Aβ_1-42， low density lipoprotein receptor-related protein 1（LRP1）， receptor for advanced glycation endproducts （RAGE）， amyloid precursor protein （APP）， insulin degrading enzyme （IDE）， neprilysin （NEP）， microtubule associated protein 1 hydrogen chain 3（LC3）-Ⅱ/LC3-Ⅰ， phosphatidylinositol 3-hydroxy kinase（PI3K）， p-PI3K， protein kinase B （AKT）， p-AKT， mammalian target of rapamycin （mTOR）， p-mTOR， and histone deacetylase 6（HDAC6）. Finally， through the co-culture of microglial cells and neuronal SH-SY5Y cells， cell viability and Caspase-3 levels were measured to verify the protective effect of EGCG-mediated Aβ clearance on neurons. ResultsEGCG increased the activity time and frequency of APP/PS1 mice in the central area of the open field （P<0.05）， and enhanced the percentage of alternation in the Y-maze test （P<0.01）； EGCG reduced Aβ deposition in the hippocampal tissue of APP/PS1 mice and increased the number of microglia； in vitro experiments showed that EGCG improved the survival rate of Aβ-induced N9 cells （P<0.01）， upregulated RAGE activity （P<0.05）， and promoted the internalization and phagocytosis of Aβ （P<0.01）. ECGC activated microglial autophagy by downregulating the level of HDAC6 （P<0.05）， inhibiting the phosphorylation of PI3K， AKT， mTOR （P<0.001）， and increasing the LC3-Ⅱ/LC3-I ratio （P<0.001）； EGCG improved the survival rate of SH-SY5Y cells （P<0.05） and reduced the activity of Caspase-3 （P<0.01） by clearing Aβ_1-42 through microglia， and had a protective effect on neurons. ConclusionEGCG activates microglial autophagy to clear Aβ by targeting and inhibiting the HDAC6-PI3K/AKT/mTOR axis.

Objective:To investigate the characteristics of weight gain in the mid and late pregnancy of women with early pregnancy weight loss, and the relationship between weight gain and weight gain rate before the diagnosis of gestational diabetes mellitus (GDM) and GDM.Methods:A retrospective study was conducted on 2 614 singleton pregnant women who underwent prenatal care and delivered at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from January 2014 to December 2021, and whose weight decreased compared to pre-pregnancy weight by 16 weeks of gestation. The rate of weight gain in mid and late pregnancy, also weight gain and weight gain rate at each stage were analyzed. Multivariate logistic regression was used to analyze the impact of total weight gain and weight gain rate at each stage before the diagnosis of GDM on the risk of GDM.Results:The rates of weight gain in mid and late pregnancy for women with early pregnancy weight loss who were underweight, normal weight, overweight, and obese before pregnancy were (0.60±0.15), (0.59±0.18), (0.53±0.20), and (0.42±0.20) kg/week, respectively, all higher than the "Chinese Recommended Standards for Weight Gain During Pregnancy" [which are (0.37-0.56), (0.26-0.48), (0.22-0.37), and (0.15-0.30) kg/week, respectively]. The weight gain rates at each stage of mid and late pregnancy in women with early pregnancy weight loss showed a "bimodal" trend, with the first peak in weight gain rate occurring at 16-20 or 20-24 weeks of gestation [weight gain rates for underweight, normal weight, overweight, and obese women before pregnancy were 0.75 kg/week (0.44-1.00 kg/week), 0.74 kg/week (0.50-1.00 kg/week), 0.63 kg/week (0.39-0.86 kg/week), and 0.50 kg/week (0.25-0.74 kg/week), respectively] and the second peak occurring at 28-32 weeks [weight gain rates for underweight, normal weight, overweight, and obese women before pregnancy were 0.63 kg/week (0.50-1.00 kg/week), 0.63 kg/week (0.38- 0.88 kg/week), 0.60 kg/week (0.25-0.88 kg/week), and 0.50 kg/week (0.22-0.75 kg/week). As of 28 weeks and 36 weeks of gestation, 53.7% (1 404/2 614) and 77.4% (1 946/2 512) of pregnant women, respectively, reached the lower limit of the recommended weight gain for the corresponding gestational weeks. No association was found between insufficient weight gain ( aOR=0.828, 95% CI: 0.639-1.071, P=0.151) or excessive weight gain ( aOR=0.936, 95% CI: 0.598-1.465, P=0.773) before the diagnosis of GDM and the risk of GDM. However, obese women with a weight loss greater than 5% of their pre-pregnancy weight in early pregnancy and a rapid weight gain rate (> P 75) between 16-20 weeks of gestation had an increased risk of developing GDM ( aOR=32.870, 95% CI: 1.625-664.775, P=0.023). Conclusions:In clinical practice, dynamic monitoring of weight changes at various stages of pregnancy in women who lose weight in early pregnancy is recommended. Targeted weight management during mid-pregnancy for women who are obese before pregnancy and experience significant weight loss in early pregnancy may help prevent excessive gestational weight gain and decrease the risk of GDM.

Objective:To study the relationship between urinary arsenic methylation metabolism patterns and skin keratinization and pigmentation abnormalities in population exposed to arsenic through drinking water.Methods:Using a cross-sectional study method, a survey on endemic arsenic poisoning was conducted among permanent residents of drinking water endemic arsenic poisoning areas in Bayannur City, Inner Mongolia Autonomous Region in 2004 (before water improvement). In 2017 (after water improvement), 71 arsenic exposed individuals were followed up as survey subjects. According to the "Diagnosis of Endemic Arsenism" (WS/T 211-2015), the clinical grading of skin injuries (skin keratinization, pigmentation abnormalities) in the survey subjects was evaluated. Urine samples were collected for detection of arsenic methylation metabolite levels by high-performance liquid chromatography inductively coupled plasma mass spectrometry and calibrated with urinary creatinine. The changes and amplitudes of urinary arsenic methylation indicators before and after water improvement were calculated and analyzed according to the outcome of skin keratinization and pigmentation abnormalities which were divided into reduced, unchanged, and added groups.Results:(1) The changes in urinary total arsenic (TAs), inorganic arsenic (iAs), monomethyl arsenic (MMA), and dimethyl arsenic (DMA) levels in different outcome groups of skin keratinization were compared, and the differences were statistically significant ( H = 9.08, 8.77, 9.28, 8.57, P < 0.05). The changes in urinary TAs, iAs, MMA, DMA levels, iAs percentage (iAs%), DMA percentage (DMA%), and primary methylation index (PMI) in different outcome groups of skin pigmentation abnormalities were compared, and the differences were statistically significant ( H = 8.04, 10.67, 8.29, 9.14, 6.30, 9.10, 7.20, P < 0.05). (2) The comparison of amplitudes in urinary TAs, iAs, MMA, and DMA levels in different outcome groups of skin keratinization showed statistically significant differences ( H = 6.92, 7.34, 6.66, 6.16, P < 0.05). The amplitudes in urinary iAs level, iAs%, DMA%, and PMI in different outcome groups of skin pigmentation abnormalities were compared, and the differences were statistically significant ( H = 7.94, 7.61, 9.95, 7.22, P < 0.05). Conclusion:The changes pattern of urinary TAs, iAs, MMA, DMA, iAs%, DMA%, and PMI in population exposed to arsenic through drinking water is related to the transformation of skin keratinization and pigmentation abnormalities.
