Chinese medicine intestinal administration(CMIA)can avoid the degradation of drugs in gastric acid,bypass the first-pass effect of the liver,and deliver drugs directly to the lesion site.This approach increases local drug concentration,reduces drug dosage,and enhances bioavailability.This study systematically introduces the advantages,drug dosage forms,and whole-colon deliv-ery technologies of CMIA for treating UC,and reviews its mechanisms of action,including repairing intestinal epithelial layer and mu-cous layer,regulating the intestinal microbiota,improving immune function,and promoting local blood circulation.It also analyzes the current progress and limitations of research,aiming to provide a more solid theoretical basis for the treatment of UC with Chinese medi-cine and to offer references for the development of UC therapeutic drugs and administration methods.

Objective:To explore the actor-partner effect of parenting stress and parenting efficacy on children's anger-aggression and anxiety-withdrawal.Methods:A questionnaire survey measuring parenting stress, parenting efficacy and children's social and behavioral problems was conducted among 525 parents of 2-5-year-old children in five kindergartens and parent-child kindergartens in Hunan, Jiangxi and Hainan provinces during April, 2023.The descriptive analysis and Pearson correlation analysis were conducted by SPSS 27.0, the mediation analyses were done with Mplus 7.4, and the actor-partner effect was analyzed by the Web-based program APIM_SEM.Results:(1) Father's parenting stress(3.22±0.67) and mother's parenting stress(2.91±1.02) were significantly related to children's anger-aggression(2.59±1.01) ( rfather=0.31, P<0.01; rmother=0.52, P<0.01) and anxiety-withdrawal(2.64±0.97) ( rfather=0.28, P<0.01; rmother=0.50, P<0.01). (2) Mother's parenting stress negatively predicted maternal parenting efficacy( β=-0.19, P<0.01) and paternal parenting efficacy( β=-0.08, P<0.05), while father's parenting stress negatively predicted paternal parenting efficacy ( β=-0.31, P<0.01) and maternal parenting efficacy ( β=-0.17, P<0.01). Regarding the actor-partner effect, maternal parenting efficacy was dual-mode and paternal parenting efficacy was mixed-mode. (3) The mediation tests showed that, maternal parenting efficacy acted as a partial mediator between maternal parenting stress and children's anger-attack and anxiety-withdrawal, the effects were 0.037(95% CI=0.021-0.056), 0.058(95% CI=0.040-0.078), as well as between paternal parenting stress and children's anger-attack(0.022(95% CI=0.008-0.039)), and anxiety-withdrawal (0.034(95% CI=0.014-0.056)).The paternal parenting efficacy played partial mediation between paternal parenting stress and children's anger-attack and anxiety-withdrawal, the mediation effects were 0.039(95% CI=0.020-0.061) and 0.032(95% CI=0.016-0.052), as well as between maternal parenting stress and children's anger-attack(0.016(95% CI=0.003-0.031)), and anxiety-withdrawal (0.013(95% CI=0.002-0.027)). Conclusion:The parenting stress significantly increase children's anger-attack and anxiety-withdrawal behavior. Parenting stress of fathers and mothers indirectly leads to the increase of children's negative emotions and behaviors by weakening the parenting efficacy of themselves and their partners.

[Purpose]To analyze the trends of disease burden for lung cancer worldwide and in China from 1990 to 2021.[Methods]Data of the disease burden of lung cancer and population demographics in 1990 and 2021 stratified by sex and age groups for global,five SDI quintiles re-gions,and eight countries including China,Japan,Republic of Korea,United Kingdom,France,United States,Canada,and Australia were extracted from the Global Burden of Disease Study 2021(GBD 2021)database.The age-standardized mortality rate(ASMR)and age-standard-ized disability-adjusted life year rate(ASDR)of lung cancer attributable to 7 level-3 risk factors in China for 1990 and 2021 were also extracted.Counterfactual analysis was used to decompose changes in lung cancer deaths and DALY from 1990 to 2021 into four contributing factors:popu-lation size,population structure,age-standardized incidence or prevalence,and lung cancer case fatality or disease severity.The percentage changes in lung cancer deaths and DALY attributed to these four factors were calculated respectively.[Results]In 2021,there were 934 704 new cases and 814 364 deaths of lung cancer in China.From 1990 to 2021,the incidence,preva-lence,mortality,and DALY rates of lung cancer in China increased faster than those worldwide and in high-middle SDI regions,which was similar to Japan and Republic of Korea.In contrast,the mortality rates of lung cancer decreased in United States and United Kingdom;and the DALY rates of lung cancer decreased in United States,United Kingdom,Canada and Australia.From 1990 to 2021,the age-related lung cancer deaths and DALY in China increased by 193.91％and 146.20％,respectively.The primary contributor to the increase in lung cancer deaths was population aging(102.82％)among men and rising age-standardized incidence(119.00％)among women,while the primary contributor to the increase in DALY was rising age-standardized prevalence for both men(153.12％)and women(218.77％).In 2021,the top three risk factors contributing to lung cancer ASMR and ASDR in China were smoking,particulate matter pollution and occupational carcinogen exposure.Compared with 1990,the ASMR of lung cancer and its proportion at-tributable to particulate matter pollution and low dietary fruits were decreased,while the propor-tions in ASDR of lung cancer attributable to smoking and secondhand smoke increased.[Conclu-sion]Lung cancer is a major public health challenge in China.Compared with worldwide,high-middle SDI regions and certain developed countries,China has experienced faster growth in the incidence,prevalence,mortality and DALY of lung cancer,especially among women.To reduce disease burden,sustained efforts on lung cancer prevention and control are urgently required in China.

[Purpose]To analyze the epidemiological characteristics of esophageal cancer world-wide and in China.[Methods]Data were extracted from the GLOBOCAN 2022 database.The in-cidence and mortality of esophageal cancer worldwide and in China were analyzed,stratified by sex,age group,and human development index(HDI).Spearman correlation analysis was conducted to evaluate the association between the HDI and the mortality-to-incidence ratio(MIR)of esophageal cancer.[Results]In 2022,there were an estimated 511 054 new cases and 445 391 deaths from esophageal cancer globally,with age-standardized incidence and mortality rates(ASIR and ASMR)of 5.0/105 and 4.3/105,respectively.In China,there were an estimated 224 012 new cases and 187 467 deaths accounting for 43.8％and 42.1％of global totals,respectively.Both the new cases and deaths of esophageal cancer in China ranked the first worldwide.The ASIR and ASMR in China were 8.3/105 and 6.7/105,both were as twice as the global average.The ASIR and ASMR for males were higher than those for females.The incidence and mortality of esophageal cancer increased with age,and more than 50％of global cases and deaths in individuals aged over 70 years old occurred in China.Additionally,a significantly negative correlation was ob-served between HDI and MIR of esophageal cancer(ρ=-0.67,P＜0.001),and MIR in China(0.81)was comparable to that of countries or regions with a very high HDI.[Conclusion]The burden of esophageal cancer remains significant worldwide and in China,particularly among males and the elderly.The MIR of esophageal cancer in China is still relatively high.The primary and secondary prevention measures should be strengthened to reduce the incidence and mortality of esophageal cancer.

AIM:To explore the mechanism of ac-tion and clinical significance of NLRC4 in multiple myeloma by analyzing the relative expression and clinical significance of NLRC4 mRNA in bone mar-row fluid of patients with multiple myeloma(MM),so as to guide the formulation of disease treatment and the evaluation of clinical prognosis.METHODS:MMRF database and GTEx database were used to compare the expression and survival correlation of inflammatory bodies between myeloma patients and normal controls.Real-time fluorescent quanti-tative polymerase chain reaction(qPCR)was used to detect the expression of inflammatory bodies in bone marrow fluid of 26 newly diagnosed myeloma patients and 19 post-treatment myeloma patients and peripheral blood of 28 normal volunteers ad-mitted to the First Affiliated Hospital of Anhui Medi-cal University from January to September 2023.The mRNA expression differences of each inflammatory body and the correlation between NLRC4 inflamma-tory body expression and clinicopathologic fea-tures,inflammatory factor/chemokine expression of newly diagnosed patients were analyzed.RE-SULTS:Compared with the control group and the treatment group,the expression of inflammasome mRNA in the newly diagnosed group was increased except for NLRP3,and the expression of NLRC4 mRNA was significantly increased(P<0.01).The he-moglobin count,creatinine level and calcium ion level were linearly correlated with NLRC4 mRNA ex-pression level in newly diagnosed patients(P<0.05).The mRNA expression levels of IL-18,CCL-3 and NL-RC4 in newly diagnosed patients were linearly cor-related(P<0.05).CONCLUSION:NLRC4 inflammato-somes are highly expressed in MM,and promote the occurrence and development of tumor by pro-moting the production and release of inflammatory cytokines/chemokines IL-18 and CCL-3,which is of great significance for the formulation of treatment plan and clinical prognosis evaluation of multiple myeloma.

Objective To investigate the regulatory pathway of lipid peroxidation in ferroptosis and the pathogenesis of Parkinson's disease(PD)at animal level.Methods Zebrafish PD model was established by exposure to 200 μmol/L 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP).Zebrafish embryo in 48 h after fertilisation were grouped into a control group(n=100),a MPTP group(n=100),and a MPTP+Nomi group(1.5 μg/ml nomifensine,n=100).Behavioral analysis was performed on zebrafish in 5 d after fertilization for movement ability,rate and distance.The expression of α-synuclein and tyrosine hydroxylase in the zebrafish brain was detected by immu-nofluorescence assay to evaluate the activity of dopaminergic neurons(DA).The levels of iron,glutathione(GSH)and lipid peroxidation,which includes catalase(CAT),glutathione peroxidase 4(GPX4),lipid peroxide(LPO),malondialdehyde(MDA)and reactive oxygen species(ROS),were measured to verify whether iron deposition may cause damage to DA through the metabolic regulation mechanism of lipid peroxidation in iron death.Results Compared with the control group,the movement rate and distance were significantly reduced in the MPTP group(P＜0.01),while Nomi treatment obviously increased the movement rate and distance when compared with the MPTP group(P＜0.01).The MPTP group exhibited obvious DA damage in comparison with the control group,and Nomi treatment reversed the damage caused by MPTP.There was no sta-tistical difference in the CAT level in the three group(P＞0.05).The MPTP group had signifi-cantly increased levels of iron,LPO and MDA and decreased levels of GSH and GPX4 when com-pared with the control group(838.18±143.42 vs 478.53±112.58,P＜0.05;1.71±0.11 vs 1.48±0.14,P＜0.05;4.50±0.64 vs 4.23±0.13,P＜0.05;38.93±1.72 vs 45.97±2.32,P＜0.05;0.17±0.03 vs 0.39±0.04,P＜0.05).The MPTP+Nomi group had significantly increased levels of GSH and GPX4 and decreased levels of iron and LPO when compared with the MPTP group(40.79±1.02 vs 38.93±1.72,P＜0.05;0.26±0.05 vs 0.17±0.03,P＜0.05;326.75±110.95 vs 838.18±143.42,P＜0.05;1.01±0.27 vs 1.71±0.11,P＜0.05).The results of the ROS flow cytometry analysis showed that the percentages of ROS positive cells in the control group,MPTP group,and Nomi group were as follows:Histogram:31.6％,46.2％and 31.3％,Scatter plot:62.4％,73.0％and 65.7％,respectively.Conclusion Ferroptosis is found in PD zebrafish induced by MPTP exposure.Our study has clarified at animal level that the damage of DA caused by iron deposition is related to the metabolic mechanism of lipid peroxidation caused by iron death.

Objective:To evaluate the Caprini risk assessment model (Caprini RAM) for predicting lower extremity deep vein thrombosis (DVT) after a spinal cord injury (SCI).Methods:Five hundred and one SCI patients were divided into low- (0-1 points, n=130), medium- (2 points, n=43), and high-risk (≥3 points, n=328) groups according to their Caprini scores. The data covering all 501 included gender, age, cause of injury, injury site, American Spinal Injury Association classification, smoking history, surgical history, concurrent pulmonary or urinary tract infections, indwelling catheterization, comorbid type 2 diabetes or hypertension, D-dimer level, fibrinogen level, prothrombin time (PT), activated partial thromboplastin time, international normalized ratio), red blood cell (RBC) count, white blood cell count, platelet (PLT) count and neutrophil percentage. DVTs were detected using lower extremity ultrasound. The Caprini scores were treated as both categorical and continuous variables alongside the other risk factors in multivariate logistic regressions predicting DVT incidence. Generalized additive models were used for curve fitting and threshold saturation analysis, and log-likelihood ratio tests were applied to evaluate the linear relationships observed between Caprini scores and DVT incidence. Results:When the Caprini score was used as a categorical variable, a high risk score ( OR=7.264), age ( OR=1.050), D-dimer ( OR=1.11) , PT ( OR=1.494), PLT count ( OR=1.004) and lung infection ( OR=1.83) were found to be significant independent predictors of DVT. RBC was a protective factor ( OR=0.509). When the Caprini score was used as a continuous variable, lung infection lost its predictive utility. After adjusting for the risk and protective factors, the Caprini scores and the incidence of DVT showed a significant curvilinear increasing association, with a breakpoint of 3. When the Caprini score was less than 3, the incidence of DVT increased 1.83 times with a 1 point increase in the Caprini score. Beyond 3 the multiplier was 1.06. Conclusions:With the independent risk factors accounted for, Caprini scores demonstrate a curvilinear increasing relationship with DVT risk. Clinically, special attention should be given to SCI patients with Caprini scores ≥3.

Obesity represents a complex, heritable condition shaped by interactions among genetic, epigenetic, metagenomic, and environmental factors. Nevertheless, the mechanistic contributions of genetic variation and epigenetic regulation to obesity pathogenesis remain incompletely elucidated. Advances in molecular profiling technologies have enabled the identification of numerous biomarkers associated with childhood obesity phenotypes. These discoveries facilitate understanding of obesity etiology and its links to chronic diseases. This review synthesizes current research on genomic and epigenomic biomarkers influencing childhood obesity susceptibility, advances our comprehension of etiological heterogeneity and intervention strategies, and offers conceptual frameworks for precision prevention based on epigenetic mechanisms.
