Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Objective: To analyze the correlation between preschool children s emotional competence and home rearing environment in Shangrao City, so as to provide support for improving children s emotional competence development as well as their home rearing environment. Methods: A total of 1 242 children aged 3-6 years old from 10 kindergartens in Shangrao City were retrospectively investigated by stratified cluster random sampling method in December 2022, and the Children s Emotional Adjustment Scale-Preschool Version (CEAS-P) and the Home Nurture Environment Scale for children aged 3-6 were surveyed on parents of preschool children. The t-test was used to test the difference, Spearman correlation analysis and multiple linear regression were used to analyze the influencing factors of preschool children s emotional competence. Results: There were significant differences in emotional competence scores of preschool children for demographic indicators including age, place of residence, health status and whether they were only children ( F/t =5.98, 6.56, 38.00, 2.23, P <0.01). The emotional competence of preschool children was positively correlated with the home rearing environment ( r=0.62, P <0.01). Multiple linear regression analysis showed that diverse activities/play participation, social adaptation/self management, and emotional warmth/self expression in home rearing environment were positive predictors of children s emotional ability ( β =0.30, 0.28, 0.16), while neglect/intervention/punishment were negative predictors ( β =-0.09)( P <0.05). Conclusions The home rearing environment is a factor related to young children s emotional competence. It is suggested specific parenting initiatives such as enriching family activities and play, strengthening children s self adaptation and management, giving warmth and let children express emotions, and preventing child neglect, interference and punishment should be conducted to improve children s emotional competence.

Natural products are important sources for the discovery of anti-tumor drugs. Evodiamine is the main alkaloid component of the traditional Chinese herb Wu-Chu-Yu, and it has weak antitumor activity. In recent years, a number of highly active antitumor candidates have been discovered with a significant progress. This article reviews the research progress of evodiamine-based antitumor drug design strategies, in order to provide reference for the development of new drugs with natural products as leads.

Objective To explore the changes in serum energy metabolites in patients with peripheral T-cell lymphoma,and investigate serum biomarkers for monitoring peripheral T-cell lymphoma from the perspective of energy metabolism.Methods Multiple/selected reaction monitoring(MRM/SRM)was used to detect the energy-related metabolites in the sera of 16 patients with newly diagnosed peripheral T-cell lymphoma admitted in the Hematology Medical Center of the Second Affiliated Hospital of Army Medical University from November 2020 to December 2021,as well as 10 recruited healthy volunteers.The corresponding clinical data including medical history,laboratory results and image data were collected and retrospectively analyzed.Results Significant differences were seen in the contents and expression profiles of serum energy metabolism-related products between the patients and the healthy volunteers.The patients had significantly reduced serum contents of cyclic AMP,succinate,citrate and cis-aconitate(P＜0.05),and elevated D-glucose 6-phosphate content(P＜0.05).The serum contents of citrate and succinate were negatively correlated with the risk stratification(low-,moderate-and high-risk)and clinical stage of the disease(P＜0.05).Meanwhile,there was a negative correlation between the contents of L-malic acid and citrate and the mid-term efficacy evaluation results,such as complete/partial response(CR/PR)or stable disease(SD)(P＜0.05).For patients with extranodal NK/T cell lymphoma(n=10),there were also significant reductions in the contents of cyclic AMP,succinate,citrate,isocitrate and cis-aconitate in the sera of patients compared with healthy volunteers(P＜0.05),and the contents of citrate and succinate were negatively correlated with the clinical stage(P＜0.05)and were rather correlated with mid-term efficacy evaluation results(CR/PR or SD)(P＜0.05).For patients with angioimmunoblastic T-cell lymphoma(n=6),the serum contents of cyclic AMP,citrate and succinate were significantly lower,while the content of D-glucose 6-phosphate was higher when compared with the healthy volunteers(P＜0.05),and the content of succinate was negatively correlated with both clinical stage and risk grade of the patients(P＜0.05).Conclusion There are 5 serum differential metabolites identified between patients with peripheral T-cell lymphoma and healthy controls,and succinate and citrate are expected to be serum biomarkers of peripheral T-cell lymphoma.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

To optimize the formulation and technology of oxymatrine-astragaloside IV coloaded liposomes (Om-As-Lip) based on quality by design (QbD) principles, and further to verify the feasibility of its amplification process, Om-As-Lip was prepared by ethanol injection combined with pH gradient method. The critical material attributions of Om-As-Lip were evaluated by dual-risk analysis tools and Plackett-Burman design (PBD). The formulation of Om-As-Lip was further optimized with the Box-Behnken design (BBD). The design space was also established based on the contour plots of BBD. In order to further investigate the amplification process of Om-As-Lip, the critical process parameters of high-pressure homogenization (HPH) were optimized by single-factor test, and the quality of the final product was also evaluated. The results of risk analysis and PBD confirmed that the astragaloside concentration, cholesterol concentration, and phospholipid ratio (HSPC∶SPC) were the ctitical material attributes. The model established by BBD had a good predictability, and the optimized mass ratio of As to phospholipids was 1∶40, cholesterol to phospholipids was 1∶10, HSPC to SPC was 51∶9. The design space of Om-As-Lip was as follows: the ratio of cholesterol to phospholipids was 1∶12-1∶5 and HSPC to SPC was 1∶7-17∶3. The optimized high-pressure homogenization pressure was 600 bar, temperature was 4 ℃, and cycle times was 6 times for HPH-Om-As-Lip. The quality of Om-As-Lip prepared based on the QbD concept can meet the expected CQAs, and the formulation and technology established can provide a reliable experimental basis for its future development and applications.

Hypertriglyceridemia-associated acute pancreatitis is an inflammatory disorder of exocrine pancreas caused by metabolism disturbances of triglyceride-rich lipoproteins.Currently,hypertriglyceridemia-associated acute pancreatitis is characterized by an escalating incidence rate,a tendency for more severe cases,and a lack of therapeutic drugs.Traditional Chinese medicine has distinct advantages in treating this disease,but its theoretical framework has not yet been established.Hypertriglyceridemia-associated acute pancreatitis manifests itself as a febrile disease,aberrant accumulation of fat and turbidity may stem from dietary imbalances and visceral dysfunction in ordinary individuals.The prolonged accumulation of fat and turbidity can transform into turbid pathogen,subsequently engendering heat,constituting a pivotal pathogenic factor.Throughout the progression of the disease,the fiery pathogen consumes the fat and turbidity,resulting in the generation of toxic heat,which is a crucial mechanism in the exacerbation of the disease severity.Thus,this article posits therapeutic principles aimed at averting the transformation of fat and turbidity into turbid pathogen and counteracting toxic heat in this disease.This article reviews two key theories from traditional Chinese medicine classics relevant to hypertriglyceridemia-associated acute pancreatitis:the theory of fat-turbidity associated with hypertriglyceridemia and the febrile disease related to acute pancreatitis.Combining these traditional theories with modern research on the mechanisms that intensify hypertriglyceridemia-associated acute pancreatitis and the corresponding targets of traditional Chinese medicine,it suggests that the pathogenesis of"fat-turbidity-toxic heat"serves as the theoretical basis of traditional Chinese medicine for the aggravated severity of hypertriglyceridemia-associated acute pancreatitis.The article aims to offer new insights for the treatment of hypertriglyceridemia-associated acute pancreatitis.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective To investigate the effect of icotinib on right ventricular remodeling in rats with monocrotaline(MCT)-induced pulmonary hypertension(PH).Methods Sprague-Dawley rats were randomly divided into control group(0.3％sodium carboxymethyl cellulose),model group and low,high dose experimental groups(30,60 mg·kg-1 icotinib),8 rats in each group.PH rat model was established by single intraperitoneal injection of 60 mg·kg-1 MCT in model group and low,high dose experimental groups.The drug was administered continuously for 4 weeks after MCT injection.The hemodynamic indexes of each group were detected.Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling(TUNEL)staining was used to detect the apoptosis of right ventricular cardiomyocytes.The protein levels of B cell lymphoma-2(Bcl-2),Bcl-2 associated X protein(Bax),cleaved cysteine aspartic acid specific protease-3(cleaved-caspase-3),epidermal growth factor receptor(EGFR),phosphorylated EGFR(p-EGFR),optic atrophy 1(Opa1)and mitofusin 2(Mfn2)were detected by Western blot analysis.Results The right ventricular systolic pressure in low,high dose experimental groups and control group,model group were(38.58±4.98),(34.15±3.88),(23.66±2.45)and(45.07±5.78)mmHg;the mean pulmonary artery pressure were(27.85±3.77),(24.25±3.09),(17.33±2.46)and(33.07±4.15)mmHg;the right ventricle(RV)to left ventricle+septum were(36.38±5.51)％,(33.63±4.69)％,(22.25±2.96)％and(42.50±7.33)％;the RV to tibial length were(69.33±7.86),(62.69±7.17),(49.12±6.42)and(78.22±9.07)mg·cm-1.There were significant differences in the above indexes between low,high dose experimental groups and model group(all P＜0.01).There were significant differences in Bcl-2,Bax,cleaved caspase-3,p-EGFR,Opa1,Mfn2 between low,high dose experimental groups and model group(P＜0.05,P＜0.01).Conclusion Icotinib can inhibit right ventricular remodeling in PH rats induced by MCT,and its mechanism may be related to reducing the phosphorylation level of EGFR in the right ventricle,alleviating mitochondrial dysfunction and inhibiting cardiomyocyte apoptosis.

AIM To explore the mechanism of Yiqi Wenyang Huwei Decoction on airway inflammation improvement of rats with bronchial asthma based on IL-25/NF-κB signaling pathway.METHODS 60 rats were randomly divided into the control group,the model group,the dexamethasone group(0.2 mg/mL),the low-dose,medium-dose and high-dose Yiqi Wenyang Huwei Decoction groups(1,2,4 g/mL),with 10 rats in each group.Intraperitoneal injection of ovalbumin(OVA)and aluminum hydroxide suspension was applied to establish the rat asthma model,followed by 2-week corresponding dosing of the drugs.The rats of each group had their daily diet,mental status,hair growth and respiration observed;their differential count of inflammatory cells in bronchoalveolar lavage fluid(BALF)detected by automatic hematology analyzer;their pathological changes of lung tissue observed by HE staining;their pulmonary IL-25 protein expression detected by immunohistochemistry(IHC);their levels of IL-4,IL-5 and IL-13 in BALF measured by ELISA;their pulmonary expression of IL-25 and TRAF6 mRNA detected by RT-qPCR;and their pulmonary protein expressions of IL-25,TRAF6,IκBα,p-IκBα,NF-κB p65 and p-NF-κB p65 detected by Western blot.RESULTS Compared with the control group,the model group displayed severe damage of the lung tissue and infiltration of a large number of inflammatory cells;increased number of inflammatory cells and levels of IL-4,IL-5 and IL-13 in BALF(P<0.01);increased mRNA expressions of IL-25 and TRAF6,and pulmonary protein expressions of IL-25,TRAF6,p-IκBα/IκBα and p-NF-κB p65/NF-κB p65(P<0.01).Compared with the model group,all of the Yiqi Wenyang Huwei Decoction groups shared improved pulmonary infiltration of inflammatory cells;decreased number of inflammatory cells and levels of IL-4,IL-5 and IL-13 in BALF(P<0.05,P<0.01);and decreased mRNA expressions of IL-25 and TRAF6,and pulmonary protein expressions of IL-25,TRAF6,p-IκBα/IκBα and p-NF-κB p65/NF-κB p65(P<0.01).CONCLUSION Yiqi Wenyang Huwei Decoction can inhibit the airway inflammation in the rat model of bronchial asthma,which may be related to the inhibited activation of IL-25/NF-κB signaling pathway and the reduced expression of inflammatory factors.
