Objective To explore the relationship between circadian rhythm genes and the occurrence, development, prognosis, and tumor microenvironment (TME) of lung adenocarcinoma (LUAD). Methods The Cancer Genome Atlas data were used to evaluate the expression, copy number variation, and somatic mutation frequency of circadian gene sets in LUAD. Gene ontology, Kyoto encyclopedia of genes and genomes, and gene set enrichment analysis were used to explore the potential mechanisms by which circadian rhythm genes affected LUAD progression. Cox regression, least absolute shrinkage and selection operator regression, support vector machine recursive feature elimination, and random forest screened circadian genes and established prognostic models, and on this basis constructed nomogram to predict patients’ 1-, 3-, and 5-year survival rates. Kaplan-Meier survival curves, receiver operating characteristic (ROC) curves, and time-dependent ROC curves were drawn to evaluate the predictive ability of the model, and the external dataset of GEO further verified the prognostic value of the prediction model. In addition, we evaluated the association of the prognostic model with immune cells and immune checkpoint genes. Single cell RNA sequencing (scRNA-seq) analysis was used to explore the molecular characteristics between prognostically relevant circadian genes and different immune cell populations in TME. Results Differentially expressed circadian rhythm genes were mainly enriched in biological processes related to cGMP-PKG signaling pathway, lipid and atherosclerosis, and JAK-STAT signaling pathway. Seven circadian rhythm genes: LGR4, CDK1, KLF10, ARNTL2, RORA, NPAS2, PTGDS were screened out, and a RiskScore model was established. According to the median RiskScore, samples were divided into a high-risk group and a low-risk group. Compared with patients in the low-risk group, patients in the high-risk group showed a poorer prognosis (P<0.001). Immunological characterization analysis showed that there were differences in the infiltration of multiple immune cells between the low-risk group and high-risk group. Most immune checkpoint genes had higher expression levels in the high-risk group than those in the low-risk group, and RiskScore was positively correlated with the expression of CD276, TNFSF4, PDCD1LG2, CD274, and TNFRSF9, and negatively correlated with the expression of CD40LG and TNFSF15. The scRNA-seq analysis showed that RORA and KLF10 were mainly expressed in natural killer cells. Conclusion The prognostic model based on seven feature circadian rhythm genes has certain predictive value for predicting survival of LUAD patients. Dysregulated expression of circadian genes may regulate the occurrence, progression as well as prognosis of LUAD through affecting TME, which provides a possible direction for finding potential strategies for treating LUAD from the perspective of mechanism by which circadian disorder affects immune cells.

ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis （RA） in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information， clinical data， laboratory test results， and traditional Chinese medicine （TCM） symptom information were collected for syndrome differentiation， on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study， including 88 （34.1%） patients with cold dampness obstruction syndrome， 53 （20.5%） patients with dampness and heat obstruction syndrome， 31 （12.0%） patients with wind dampness obstruction syndrome， 29 （11.2%） patients with liver-kidney deficiency syndrome， 19 （7.4%） patients with Qi-blood deficiency syndrome， 14 （5.4%） patients with phlegm-stasis obstruction syndrome， 15 （5.8%） patients with stasis obstructing collateral syndrome and 9 （3.5%） patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever， 28-tender joint count （TJC28）， and 28-joint disease activity score （DAS28）-C-reactive protein （CRP） and higher central sensitization， cold feeling of joints， fear of wind and cold， cold limbs， and abdominal distention than the group of other syndromes （P<0.05）. The binary logistic regression analysis showed that central sensitization （OR 5.749， 95%CI 2.116-15.616， P<0.001） and DAS28-CRP （OR 0.600， 95% CI 0.418-0.862， P=0.006） were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization， cold feeling of joints， abdominal distension and may be a clinical syndrome associated with central sensitization.

Objective To determine the prognostic biomarkers and new therapeutic targets of the lung adenocarcinoma (LUAD), based on which to establish a prediction model for the survival of LUAD patients. Methods An integrative analysis was conducted on gene expression and clinicopathologic data of LUAD, which were obtained from the UCSC database. Subsequently, various methods, including screening of differentially expressed genes (DEGs), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and Gene Set Enrichment Analysis (GSEA), were employed to analyze the data. Cox regression and least absolute shrinkage and selection operator (LASSO) regression were used to establish an assessment model. Based on this model, we constructed a nomogram to predict the probable survival of LUAD patients at different time points (1-year, 2-year, 3-year, 5-year, and 10-year). Finally, we evaluated the predictive ability of our model using Kaplan-Meier survival curves, receiver operating characteristic (ROC) curves, and time-dependent ROC curves. The validation group further verified the prognostic value of the model. Results The different-grade pathological subtypes' DEGs were mainly enriched in biological processes such as metabolism of xenobiotics by cytochrome P450, natural killer cell-mediated cytotoxicity, antigen processing and presentation, and regulation of enzyme activity, which were closely related to tumor development. Through Cox regression and LASSO regression, we constructed a reliable prediction model consisting of a five-gene panel (MELTF, MAGEA1, FGF19, DKK4, C14ORF105). The model demonstrated excellent specificity and sensitivity in ROC curves, with an area under the curve (AUC) of 0.675. The time-dependent ROC analysis revealed AUC values of 0.893, 0.713, and 0.632 for 1-year, 3-year, and 5-year survival, respectively. The advantage of the model was also verified in the validation group. Additionally, we developed a nomogram that accurately predicted survival, as demonstrated by calibration curves and C-index. Conclusion We have developed a prognostic prediction model for LUAD consisting of five genes. This novel approach offers clinical practitioners a personalized tool for making informed decisions regarding the prognosis of their patients.

Objective: To explore the correlation and lag effects of environmental factors on pediatric respiratory disease visits at hospital, so as to provide scientific basis for disease prediction and optimizing clinical diagnosis and treatment. Methods: Data from 503 889 pediatric respiratory disease outpatient and emergency visits a central hospital in Minhang District of Shanghai between 2017 and 2019, along with concurrent meteorological data were collected. A distributed lag non-linear models (DLNM) was constructed to explore the specific relationship between pediatric respiratory disease consultations and various environmental factors and to quantify the cumulative lag effects of environmental factors on respiratory disease consultations. Results: Among the environmental factors, temperature, fine particulate matter (PM 2.5 ), inhalable particulate matter (PM 10 ), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) were associated with pediatric respiratory disease visits. After adjusting for temperature, PM 2.5 and PM 10 concentrations did not show significant immediate or lag effects. The relative risk (RR) of pediatric respiratory disease visits increased with rising NO 2 concentrations. When NO 2 concentration ≥55 μg/m 3, significant immediate and lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.05, 1.13, 1.17, and 1.21( P <0.05). The RR values showed an inverted “U” shaped relationship with SO 2 concentrations. When SO 2 concentration ≥5 μg/m 3, significant lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.03 , 1.03, and 1.04 ( P <0.05). Conclusion High concentrations of NO 2 and SO 2 increase the risk of pediatric respiratory disease visits, with observable lag effects.

Platelets are indispensable for physiological hemostasis and pathological thrombus formation, and platelet adhesion to endothelial collagen is a critical initial step in thrombus formation, often overlooked in current antiplatelet therapies. This study aims to elucidate how ginsenoside CK enhances hemodynamic circulation, alleviates stasis, and proposes therapeutic mechanisms. Inspired by the effects on improving microcirculatory disturbances in an acute soft tissue injury model, CK was identified as a PHD2 inhibitor, effectively suppressing platelet adhesion to collagen. It was proposed that targeting PHD2 regulates collagen hydroxylation modification, thereby influencing the formation of its three-dimensional structure, reducing the binding affinity between VWF and collagen, and ultimately suppressing thrombotic events. The efficacy of this mechanism was subsequently confirmed through a mouse DIC model, demonstrating the feasibility of CK in alleviating circulatory disorders. It is worth noting that when Phd2 was knocked down in mice's lungs, pulmonary embolism was significantly reduced. Additionally, PHD2 inhibitors approved for other diseases have exhibited similar anti-thrombotic effects. Moreover, when PHD2 inhibitors were combined with aspirin, they more effectively inhibited arterial thrombosis in rats. The findings offer valuable insights into potential targets for developing antiplatelet drugs or expanding therapeutic applications for existing PHD2 inhibitors in treating thrombotic diseases.

Objective: To explore the association between greenness surrounding school and aggression among primary school students, and to explore the potential mediating roles of social support, loneliness, particulate matter (PM2.5) and Nitrogen Dioxide (NO2) in this association, in order to provide a scientific reference for preventing and ameliorating aggressive behaviors of primary school students. Methods: The data was used from a survey of children and adolescents conducted in 2015. The Chinese version of the Buss-Warren Aggression Questionnaire was used to assess total and subtypes of aggression, and the mean values of normalized difference vegetation index (NDVI) of 100 m, 500 m, 1 000 m circular buffers surrounding school were used to indicate the participants greenness exposure. PM2.5 and NO2 datas were obtained from the China High Air Pollutants Dataset.Generalized Linear Mixed Models were used to assess the associations of greenness surrounding school with total and subtypes of aggression. Results: Per IQR increment of NDVI-500 m [OR(95%CI)=1.09(1.03-1.15)] and NDVI-1 000 m[OR(95%CI)=1.07(1.02-1.13)] were positively correlated with physical aggression among primary school children, and per IQR increment of NDVI-100 m [OR(95%CI)=0.94(0.90-0.99)], NDVI-500 m [OR(95%CI)=0.93(0.89-0.98)] and NDVI-1 000 m [OR(95%CI)=0.95(0.91-1.00)] were negatively associated with verbal aggression (P<0.05). Mediation analyses revealed that social support partially mediated the association between the NDVI-500 m and physical aggression (mediation ratio:18.0%) and verbal aggression (mediation ratio:-8.3%) among primary school students, and loneliness partially mediated the association between the NDVI-500 m and physical aggression and verbal aggression among elementary school students effects, with proportion mediated ratios of -10.0% and 21.0%, respectively (P<0.05). Conclusions Exposure to school surrounding greenness is likely to associated with physical aggression and verbal aggression in primary school students, and social support and loneliness may partially mediate these associations.

Objective To investigate the clinical manifestations of familial adenomatous polyposis(FAP).Methods The clinical data of 100 patients with FAP diagnosed in the First Affiliated Hospital of Zhengzhou University from 2011 to 2021 were analyzed retrospectively.Results The main clinical manifestations were bloody stool(44.0%),abdominal pain(40.0%),changes of stool characteristics(25.0%),abdominal distension(18.0%)and diarrhea(17.0%);The most common types of adenomas were villous tubular adenoma(44.9%)and tubular adenoma(32.1%);Extraintestinal manifestations:3 cases of desmoid fibroma,2 cases of osteoma and 1 case of lipoma.47 cases of gastric polyps and the mostly pathological type was fundic gland polyp(34.0%).18 cases of duodenal polyps including 6 cases of adenomatous polyps and most were located at descending duodenum(61.1%).Adenoma canceration occurred in 21 patients.The average age was 38.7 and the canceration mainly occurs in the rectum.The gender,family history,age of onset,number of adenomas,diameter and pathological type of adenomas were statistically compared between patients with and without canceration.It was found that there were significant differences in gender,average age of onset,number of adenoma polyps,diameter of adenoma and pathological type between the two groups(P<0.05).Conclusions FAP is mainly characterized by bloody stool and abdominal pain,with high canceration rate.The risk factors include the age of onset,the number and size of adenomas and the pathological type.The main pathological types are villous tubular adenoma and tubular adenoma.At present,preventive colorectal resection is still the most effective way to treat FAP.No matter what type of methods patients choose,they should be followed up strictly under endoscopy in order to find the lesions in time and treat if necessary.

Objective To study the effects of Guizhi Shaoyao Zhimu Decoction on factors related to bone destruction and bone protection in rats with collagen-induced arthritis(CIA)based on osteopro-tegerin(OPG)/receptor activator of NF-κB ligand(RANKL)/receptor activator of NF-κB(RANK)signaling pathway.Methods According to the body weight,60 female Wistar rats were randomly di-vided into the following six groups:the normal group,the model group,the Triperygium wilfordii mul-tiglucoside group(0.01 g/kg),the Guizhi Shaoyao Zhimu Decoction low-dose group(8.6 g/kg),the Guizhi Shaoyao Zhimu Decoction medium-dose group(17.2 g/kg),and the Guizhi Shaoyao Zhimu Decoction high-dose group(34.4 g/kg)(n=10 rats per group).The rats in all groups except for the normal group were given 100 μg bovine type Ⅱ collagen on the 1st and 8th days to establish the CIA model,and was injected into the left foot sole and tail root of the rats.After the successful modeling,the rats were treated by gavage for 4 weeks.The general state,body weight,and arthritis index(AI)score of rats were recorded,and the contents of RANKL and OPG in rat serum were determined by enzyme-linked immunosorbent assay.The mRNA and protein expressions of RANKL,RANK,and OPG in the ankle joint were determined through real-time PCR and Western blotting,respectively.Results Com-pared with the normal group,the general state of the model group was poor,the toe swelling was obvious,the AI score was increased,the serum RANKL content was increased,the serum OPG content was de-creased,and the mRNA and protein expressions of RANKL and RANK in the ankle joint were increased(P＜0.05).Compared with the model group,the degree of toe swelling and the AI score of rats in the Guizhi Shaoyao Zhimu Decoction low-,medium-,and high-dose groups were decreased,the serum RANKL content was decreased,the serum OPG content was increased,the mRNA and protein expres-sions of RANKL and RANK in the ankle joint were decreased,the mRNA and protein expressions of OPG were increased,and the RANKL/OPG ratio of the ankle joint was decreased(P＜0.05).Conclusion Guizhi Shaoyao Zhimu Decoction can improve the destruction of joint bone in CIA rats,and its mecha-nism of action may be related to reducing RANKL level,reducing RANKL/OPG ratio,and regulating bone balance.
