Objective To investigate the relationship between stationing years of personnel on an island and their traditional Chinese medicine(TCM)constitution,thus providing a reference for adjusting the health status of stationed personnel,preventing and treating diseases.Methods Based on The Scale of Constitution in Chinese Medicine Questionnaire,TCM constitution of 734 personnel stationed on an island was investigated.Pearson χ2 method was used for data analysis.Results Of the 734 personnel stationed on an island 345(47.0%)were of the balanced constitution type and 389(53.0%)were of the biased constitution types.Among the people with biased constitution types,composite constitution accounted for 80.5%(313 people)and the simple accounted for the rest(19.5%,76 people).The top three types of the biased were dampness heat(15.2%),qi deficiency(14.0%),and yin deficiency(10.7%).The distribution of TCM constitution types was significantly different in terms of stationing years on the island(P<0.05).There was a significant difference in the balanced type and yin deficiency type between people with stationing time≤2 years and>8 years(P<0.05).There was a significant difference in qi deficiency type and qi depression type between people with stationing time≤2 years and>5 years(P<0.05).Compared to people with stationing time≤2 years,significant difference was found in yang deficiency type in people with stationing time ranging from 2 to 5 years and those with>8 years(P<0.05).There were significant differences in the phlegm dampness type,blood stasis type,and specific diathesis type between people with stationing time≤2 years and people with stationing time ranging from>2～5 years and>8 years(P<0.05).There were significant differences in the dampness heat type between people with stationing time≤2 years and people with stationing time ranging from>5～8 years and>8 years,between pepole with stationing time ranging from>2～5 years and people with stationing time>8 years(P<0.05).Conclusion The dampness heat type,qi deficiency type and yin deficiency type are common biased TCM constitution in personnel stationed on islands.The longer the time spent on islands,the greater the possibility of forming biased constitution.

Our previous research demonstrated that the Wenxia Changfu Formula (WCF), as a neoadjuvant therapy, inhibits M2 macrophage infiltration in the tumor microenvironment and prevents lung cancer metastasis. Given tumor-associated macrophages (TAMs) in epithelial-mesenchymal transition (EMT), this study investigated whether WCF impedes lung cancer metastasis by attenuating TAM-induced EMT in non-small cell lung cancer (NSCLC) cells. Utilizing a co-culture model treated with or without WCF, we observed that WCF downregulated cluster of differentiation 163 (CD163) expression in macrophages, reduced CCL18 levels in the conditioned medium, and inhibited the growth, invasion, and EMT of NSCLC cells induced by macrophage co-culture. Manipulation of CCL18 levels and Src overexpression in NSCLC cells revealed that WCF's effects are mediated through CCL18 and Src signaling. In vivo, WCF inhibited recombinant CCL18 (rCCL18)-induced tumor metastasis in nude mice by blocking Src signaling. These findings indicate that WCF inhibits NSCLC metastasis by impeding TAM-induced EMT via antagonistic modulation of CCL18, providing evidence for its potential development and clinical application in NSCLC patients.

Autoimmunity and the activation of immune cells are closely related to the occurrence of chronic spontaneous urticaria, while the gut microbiota participates in multiple physiological activities including the regulation of the host's immunity. Gut microbiota in patients with chronic spontaneous urticaria has unique structural composition and metabolic features. Gut microbiota imbalance and secondary short-chain fatty acid deficiency may be important causes for the occurrence of the disease and aggravation of inflammation. Studies have shown that probiotics can improve the clinical manifestations of patients with urticaria. This review summarizes the research progress in the correlations of gut microbiota and short-chain fatty acids with chronic spontaneous urticaria.

BACKGROUND:Ferroptosis-related genes have been found to play an important role in the pathogenesis of rheumatoid arthritis.However,there is currently a lack of immune expression of ferroptosis-related signature genes in rheumatoid arthritis and the construction of competing endogenous RNA(CeRNA)interaction networks.Machine learning,as a powerful signature gene selection algorithm based on bioinformatics,can more accurately identify ferroptosis-related signature genes that dominate the pathogenesis of rheumatoid arthritis. OBJECTIVE:To screen ferroptosis-related signature genes in rheumatoid arthritis using bioinformatics and machine learning methods,and to analyze the correlation between ferroptosis-related signature genes and immune infiltration and the construction of CeRNA network of ferroptosis-related signature genes. METHODS:Rheumatoid arthritis-related microarrays were obtained from the GEO database,and ferroptosis-related genes and their differential gene expression were extracted using R language.The differentially expressed genes were screened using machine learning methods.The LASSO regression and SVM-RFE methods were used for signature gene screening,and the genes filtered by both were re-intersected to finally obtain the signature genes in rheumatoid arthritis.Receiver operating characteristic curves were used to assess the accuracy of the screened signature genes for disease diagnosis.Immune infiltration of rheumatoid arthritis and normal synovial tissues was analyzed using the CIBERSORT algorithm,and the correlation between the signature genes and immune cells was analyzed.Finally,the CeRNA network of ferroptosis-related signature genes for rheumatoid arthritis was constructed and the disease signature genes were validated. RESULTS AND CONCLUSION:A total of 150 ferroptosis-related genes in rheumatoid arthritis were obtained,including 55 up-regulated genes and 95 down-regulated genes.GO and KEGG enrichment analyses identified 18 GO significantly correlated entries and 30 KEGG entries respectively,mainly involving metal ion homeostasis,ferric ion homeostasis and oxidative stress response.Machine learning analysis finally identified disease signature genes GABARAPL1 and SAT1.GSEA analysis found that adipocytokine signaling pathway,drug metabolism cytochrome P450,fatty acid metabolism,PPAR signaling pathway,tyrosine metabolism were mainly concentrated when GABARAPL1 was highly expressed,and chemokine signaling pathway,intestinal immune network on IGA production were mainly concentrated when SAT1 was highly expressed.Immune infiltration analysis found that nine immune cells were significantly different in rheumatoid arthritis and normal synovial tissues,in which plasma cells,T-cell CD8,and T-cell follicular helper were highly expressed and the rest were lowly expressed in the disease group.Single gene and immune cell correlation analysis found that GABARAPL1 was positively correlated with dendritic resting cells,activated NK cells,and macrophage M1,with the most significant correlation with dendritic resting cells,while SAT1 was positively correlated with T cell CD4 and γδ T cells and negatively correlated with NK resting cells.GSVA analysis found that SAT1 was upregulated in ascorbic acid and aldehyde metabolism,while downregulated in B-cell receptor signaling pathway,Toll-like receptor signaling pathway,T-cell receptor signaling pathway,and natural killer cell-mediated cytotoxicity.GABARAPL1 showed a down-regulation trend in PPAR signaling pathway,metabolism of nicotinate and nicotinamide,tryptophan metabolism,fatty acid metabolism,and steroid biosynthesis.Sixty long non-code RNAs may play a key role in the development of rheumatoid arthritis.To conclude,the occurrence of rheumatoid arthritis is significantly correlated with the abnormal expression of rheumatoid arthritis-induced ferroptosis-related signature genes,and the signature genes induce disease development via relevant signaling pathways.By analyzing rheumatoid arthritis-related long non-code RNAs-mediated ceRNA networks,potential therapeutic targets and signaling pathways can be identified to further elucidate its pathogenesis and provide a reference basis for subsequent experimental studies.

Objective:To investigate the influencing factors for lymph node metastasis and prognosis in early gastric cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 011 patients with early gastric cancer who were admitted to the Zhejiang Cancer Hospital from January 2010 to December 2019 were collected. There were 561 males and 450 females, aged (58±11)years. All patients underwent radical resection of gastric cancer and the lymph node metastasis of each group was identified according to the pathological examination on patients' surgical specimens. Observation indicators: (1) lymph node metastasis in early gastric cancer; (2) influencing factors for lymph node metastasis in early gastric cancer; (3) influencing factors for prognosis in early gastric cancer. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was analyzed using the non‐parameter rank sum test. Univariate analysis was conducted using the Log-Rank test and Logistic regression model, and multivariate analysis was conducted using the Logistic stepwise regression model and COX step-wise regression model. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-Rank test was used for survival analysis. Results:(1) Lymph node metastasis in early gastric cancer. The lymph node metastasis rate of 1 011 patients with early gastric cancer was 23.640%(239/1 011), in which the lymph node metastasis rate of patients with T1a stage gastric cancer was 11.883%(53/446), and the lymph node metastasis rate of patients with T1b stage gastric cancer was 32.920%(186/565). There were 239 patients with lymph node metastasis mainly concentrated in the first station, including 7 cases with No.1 lymph node metastasis, 11 cases with No.2 lymph node metastasis, 135 cases with No.3 lymph node metastasis, 59 cases with No.4 lymph node metastasis, 39 cases with No.5 lymph node metastasis, 91 cases with No.6 lymph node metastasis, 6 cases with No.7 lymph node metastasis, 8 cases with No.8 lymph node metastasis, 8 cases with No.9 lymph node metastasis and 6 cases with No.10 lymph node metastasis. Multiple lymph node metastases may exist in the same patient. For lymph node metastasis in different tumor sites, there were 4 cases, 2 cases and 1 case of lymph node metastasis in the No.2, 3 and 5 lymph node in patients with upper gastric cancer. There were 3 cases, 7 cases, 36 cases, 15 cases, 3 cases and 5 cases of lymph node metastasis in the No.1, 2, 3, 4, 5 and 6 lymph node in patients with middle gastric cancer. There were 4 cases, 97 cases, 44 cases, 35 cases and 86 cases of lymph node metastasis in the No.1, 3, 4, 5 and 6 lymph node in patients with lower gastric cancer. (2) Influencing factors for lymph node metastasis in early gastric cancer. Results of multivariate analysis showed that tumor diameter, tumor location, degree of tumor invasion, vascular thrombus, degree of tumor differentiation were independent factors influencing lymph node metastasis in early gastric cancer ( odds ratio=1.80, 1.49, 2.65, 5.76, 0.60, 95% confidence interval as 1.29-2.50, 1.11-2.00, 1.81-3.88, 3.87-8.59, 0.48-0.76, P<0.05). (3) Influencing factors for prognosis in early gastric cancer. All 1 011 patients were followed up for 43(range, 0-135)months, and the 3-year overall survival rate was 97.32%. Results of multivariate analysis showed that age >60 years and lymph node metastasis were independent risk factors influencing prognosis in early gastric cancer ( hazard ratio=9.50, 2.20, 95% confidence interval as 3.31-27.29, 1.00-4.87, P<0.05). Results of further analysis showed that the 3-year overall survival rate was 99.37% and 94.66% in patient with age >60 years and ≤60 years, respectively, showing a significant difference between them ( χ2=25.33, P<0.05). The 3-year overall survival rate was 95.42% and 97.92% in patients with and without lymph node metastasis, respectively, showing a significant difference between them ( χ2=5.69, P<0.05). Conclusions:The lymph node metastasis rate of early gastric cancer can reach 23.640%. Tumor diameter, tumor location, degree of tumor invasion, vascular thrombus, degree of tumor differentia-tion are independent factors influencing lymph node metastasis in early gastric cancer, age >60 years and lymph node metastasis are independent risk factors influencing prognosis.

【Objective:】 To analyze the emotional status and follow-up status of the participants in the drug clinical trials in a hospital during the epidemic prevention and control, with a view to maximizing the protection of participants’ rights and interests under special circumstances. 【Methods:】 The general information, depression screening scale (PHQ-9), anxiety screening scale (GAD-7) and subject compliance assessment scale were completed online by participants with gold data questionnaire. At the same time, the status of drug clinical trials under study and the follow-up status of participants under study were collected from November 1, 2021 to December 8, 2021 and from December 9, 2021 to January 24, 2022. Excel software and SPSS18.0 software were used for data statistics and analysis. 【Results:】 During the epidemic prevention and control, there were 20 drug clinical trial projects under way in the hospital. From December 9, 2021 to January 24, 2022, the planned number of visits was 161, and the actual number of visits to the hospital was 84 (52.2%). Plus 24 participants who mailed drugs, the overall visit rate was 67.1%, among which the visit rates of oral drugs, non-oral drugs, and oral drugs combined with non-oral drugs were 79.3%, 71.9%, and 41.0% respectively. From November 1, 2021 to December 8, 2021, the planned number of visits was 166, the actual number of visits to the hospital was 157 (94.6%), and the number of telephone visits accounted for 1.8% of the total planned number of visits. The number of participants who did not take the drug and those who delayed taking the drug were both 0. The total compliance of participants was as high as 80.0%. A total of 40 valid questionnaires were retrieved, and the detection rates of depression and anxiety were 42.5% and 30.0% respectively. 【Conclusion:】 The epidemic prevention and control has a large short-term impact on the follow-up of the participants under study. The formulation of relevant follow-up measures and the conduction of classification management can not only improve the emotions of the participants to a certain extent, but also protect the rights and interests of participants, providing suggestions for the follow-up of participants under emergencies in the future.
