"Dietary inquiry" is a core component of the diagnostic system in traditional Chinese medicine （TCM）， which can be divided into three aspects including appetite， eating capacity， and food preference. Abnormalities in appetite are mainly attributed to dysfunction of the mind and impaired regulatory mechanisms. Clinical inquiry should focus on hunger sensation and the willingness to eat voluntarily. Treatment should aim to soothe the liver， regulate the spleen， nourish and calm the mind. Abnormalities in eating capacity are related to disorders of qi movement and structural dysfunction， for which inquiry should focus on whether food descends smoothly and on postprandial reactions， and the corresponding treatment is descending qi， relieving fullness， and promoting bowel movement and digestion. Abnormalities in food preference arise from damage caused by the five flavors and imbalance of visceral qi， for which inquiry should focus on dietary preferences and whether eating brings comfort. It is important to distinguish between "stomach preference" and "oral preference"， and treatment should carefully differentiate flavor tendencies and correct imbalances through appropriate dietary flavors. By refining the content of dietary inquiry， this study explores how different dimensions of eating status reflect the holistic concept and syndrome differentiation-based treatment in TCM， providing a reference for the clinical diagnosis and treatment of spleen and stomach diseases and related disorders.

Due to the difficulty of overcoming the abnormal epidermal barriers and addressing S. aureus infections without disrupting indigenous skin microbiota, effective treatment of bacterial infection atopic dermatitis (AD) remains a significant clinical challenge. Skin microbiota-derived extracellular vesicles (EVs) shows protentional for skin disease treatment, but the lack of antimicrobial activity and limited skin penetration hamper their application in bacterial infection AD treatment. Here, we developed novel nanoantibiotics by loading Lev into S. epidermidis-derived EVs (Lev@SE-EVs), with supreme antimicrobial activity, regulating epidermal immune responses and enhanced epidermal barrier functionality. The nanoantibiotics were further integrated into hyaluronic acid-based microneedle (MN) for efficient transdermal delivery of therapeutic agents and effectively treating bacterial infection in AD. Upon insertion into the skin, the rapidly released Lev@SE-EVs from MN are uptake by S. aureus in a selective manner, fibroblasts, and surrounding immune cells to exert therapeutic effects in the infected dermal layer, resulting in mitigated skin inflammation, reduced S. aureus burden and increased dermis repair. Notably, Lev@SE-EVs induce IL-17A⁺ CD8⁺ T-cell accumulation in the skin in an unrelated inflammation manner, which may represent heterologous protection. This EVs-integrated MN assisted Lev@SE-EVs to alleviate skin inflammation, repair skin, and provide an effective and safe therapeutic approach for bacterial infection AD treatment.

Chronic, unresolved inflammation correlates with persistent hepatic injury and fibrosis, ultimately progressing to hepatocellular carcinoma (HCC). Bisdemethoxycurcumin (BDMC) demonstrates therapeutic potential against HCC, yet its mechanism in preventing hepatic "inflammation-carcinoma transformation" remains incompletely understood. In the current research, clinical HCC specimens underwent analysis using hematoxylin-eosin (H&E) staining and immunohistochemistry (IHC) to evaluate the expression of fibrosis markers, M2 macrophage markers, and CXCL12. In vitro, transforming growth factor-β1 (TGF-β1)-induced LX-2 cells and a co-culture system of LX-2, THP-1, and HCC cells were established. Cell functions underwent assessment through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), flow cytometry, and Transwell assays. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blotting and immunofluorescence evaluated the differential expression of molecules. The interaction between β-catenin/TCF4 and CXCL12 was examined using co-immunoprecipitation (Co-IP), dual luciferase, and chromatin immunoprecipitation (ChIP) assays. A DEN-induced rat model was developed to investigate BDMC's role in liver fibrosis-associated HCC (LFAHCC) development in vivo. Our results showed that clinical HCC tissues exhibited elevated fibrosis and enriched M2 macrophages. BDMC delayed liver fibrosis progression to HCC in vivo. BDMC inhibited the inflammatory microenvironment induced by activated hepatic stellate cells (HSCs). Furthermore, BDMC suppressed M2 macrophage-induced fibrosis and HCC cell proliferation and metastasis. Mechanistically, BDMC repressed TCF4/β-catenin complex formation, thereby reducing CXCL12 transcription in LX-2 cells. Moreover, CXCL12 overexpression reversed BDMC's inhibitory effect on macrophage M2 polarization and its mediation of fibrosis, as well as HCC proliferation and metastasis. BDMC significantly suppressed LFAHCC development through CXCL12 in rats. In conclusion, BDMC inhibited LFAHCC progression by reducing M2 macrophage polarization through suppressing β-catenin/TCF4-mediated CXCL12 transcription.

Jasmonic acid (JA) is a common plant hormone with regulatory effects on plant growth and development. The jasmonate ZIM-domain (JAZ) proteins (JAZs), as key regulators in the JA signaling pathway, are involved in multiple biological processes such as anthocyanin accumulation, flowering time modulation, and secondary metabolite synthesis in plants. JAZs are essential components of many regulatory signaling networks. The JAZ genes, members of the plant-specific TIFY family, have been identified in the genomes of a variety of horticultural plants. Here, we summarized the research progress in the roles of JAZs in horticultural plants, aiming to give insights into the further study of the biological functions and regulatory networks of JAZ genes in plants.

Objective To analyze the trends in disease burden and risk factors of depression among the elderly population in China from 1990 to 2021,and to provide a theoretical basis for the prevention,treatment,and policy-making of geriatric depression in China.Methods Data on the disease burden of geriatric depres-sion in China from 1990 to 2021,including the number of incident cases,disability-adjusted life years(DALYs),incidence rate,and DALY rate,were extracted from the 2021 Global Burden of Disease(GBD)database.The Joinpoint regression model was used to analyze the trends by calculating the annual percentage change(APC)and average annual percentage change(AAPC).The autoregressive integrated moving average(ARIMA)model was employed to predict the disease burden of geriatric depression over the next five years.Population attributable fractions(PAFs)were used to describe the risk factors for geriatric depression in China in 1990 and 2021.Results From 1990 to 2021,the number of incident cases and the incidence rate of geri-atric depression in China showed an overall upward trend.The most significant increase in incidence was ob-served in the 60-64 age group,while the prevalence rate increased notably in the ≥ 95 age group.The DALY rate showed the most pronounced upward trend in the 65-69 age group.The incidence,prevalence,and DALY rates of geriatric depression were higher in women than in men.Major risk factors included child-hood sexual abuse and intimate partner violence,with the impact of intimate partner violence being particular-ly significant among women.The ARIMA model predicted that the incidence,prevalence,and DALY rates of geriatric depression in China would decline over the next five years,with a greater decline observed in women than in men.Conclusions From 1990 to 2021,the incidence,prevalence,and DALY rates of geriatric de-pression in China showed an overall upward trend,with higher rates observed in women than in men.Greater attention should be paid to the elderly female population,with a focus on early prevention to reduce the dis-ease burden of geriatric depression.

Background China is a major coal producer and consumer country in the world. Coal workers' pneumoconiosis (CWP) is a primary factor endangering the occupational health of coal miners. Research on the disease burden of CWP and its changing trend is significant for disease prevention & control and associated policies. Objective To analyze the disease burden of CWP in China from 1990 to 2021 and its changing trend, and predict the disease burden from 2022 to 2035. Methods Using the Global Burden of Disease Study (GBD) database of 2021, numbers ofincident cases, prevalent cases, deaths, and disability-adjusted life years (DALYs) as well as crude and age-standardized rates of CWP in China were retrieved. Linear regression model was used to calculate the estimated annual percentage change (EAPC) of the age-standardized rates. Joinpoint regression model was used to analyze the temporal trend of disease burden and the disease burden of different sexes and age groups, and Bayesian age-period-cohort (BAPC) model was used to forecast the trend of CWP disease burden. Results In 1990, the incident, prevalent, and deaths cases of CWP in China were 3266, 18872, and 1561, respectively, and the DALYs of CWP were 44614.718 person-years. In 2021, the incident, prevalent, and deaths cases of CWP were 3446, 23975, and 1229, respectively, and the DALYs of CWP were 29610.754 person-years. From 1990 to 2021, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP in China all showed a downward trend, with the EAPCs of −3.121%, −2.532%, −4.018%, and −4.268%, respectively. The disease burden of CWP in China was mainly concentrated in the male population. The annual average percent change analysis indicated that each standardized rate showed a fluctuating downward trend in different periods. The BAPC model showed that from 2022 to 2035, the age-standardized rates of CWP in China would continue to decline steadily. In 2035, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP would be reduced to 0.10 per 100000, 0.74 per 100000, 0.03 per 100000, and 0.74 per 100000, respectively. Conclusion The disease burden contributed by CWP in China generally show a downward trend from 1990 to 2021, and it is expected that the age-standardized rates will continue to decline steadily from 2022 to 2035.

Objective:To investigate the value of MRI combined with serum long non-coding RNA (lncRNA) KCNQ1OT1 and microRNA-204-5p (miR-204-5p) in predicting axillary lymph node metastasis in breast cancer patients.Methods:A total of 70 patients with breast cancer who were surgically diagnosed in the No.2 Hospital of Baoding, Hebei Province from January 2020 to December 2022 were selected as the study objects. Patients were divided into metastatic group ( n=31) and non-metastatic group ( n=39) according to the status of lymph node metastasis. The MRI features and the levels of serum lncRNA KCNQ1OT1 and miR-204-5p were compared between the two groups. Receiver operator characteristic (ROC) curve was used to evaluate the predictive efficacy of the three detections alone and in combination for axillary lymph node metastasis in breast cancer. Results:There were statistically significant differences in tumor maximum diameter ( χ2=4.28, P=0.039) and Ki-67 expression ( χ2=10.88, P=0.001) between the metastatic and non-metastatic groups. There were statistically significant differences between the breast cancer axillary lymph node metastatic group and the non-metastatic group in the mode of internal reinforcement type ( χ2=6.60, P=0.037), peripheral vessel diameter ( t=4.33, P<0.001), number of peripheral vessel roots ( t=4.38, P<0.001), apparent diffusion coefficient ( t=3.59, P=0.001), and MRI lymph node status ( χ2=29.70, P<0.001). The level of serum lncRNA KCNQ1OT1 in metastatic group was higher than that in non-metastatic group (1.41±0.32 vs. 0.99±0.18, t=6.94, P<0.001), and the level of miR-204-5p was lower than that in non-metastatic group (0.72±0.17 vs. 1.03±0.21, t=6.66, P<0.001). Bioinformatics analysis showed that miR-204-5p may have a targeting relationship with lncRNA KCNQ1OT1. ROC curve analysis showed the area under the curve of MRI features, serum levels of lncRNA KCNQ1OT1, miR-204-5p and their combined detection to predict lymph node metastasis of breast cancer patients were 0.823, 0.858, 0.843, 0.946, respectively. The predictive efficacy of the combined detection was better than that of MRI features and serum lncRNA KCNQ1OT1 and miR-204-5p levels alone ( Z=3.29, P=0.001; Z=2.07, P=0.038; Z=2.23, P=0.026) . Conclusions:Serum lncRNA KCNQ1OT1 level is up-regulated and the level of miR-204-5p is down-regulated in patients with axillary lymph node metastasis of breast cancer. And the combination of MRI features with serum lncRNA KCNQ1OT1 and miR-204-5p has high predictive efficacy in predicting lymph node metastasis in breast cancer patients.

Objective:To investigate the characteristics and determinants of total scores of cerebral small vessel disease (CSVD) and to analyze the factors associated with enlarged perivascular space (EPVS) grading in pilots.Methods:The physical examination data of 72 pilots who were hospitalized and diagnosed with CSVD by MRI in the Air Force Medical Center (General Hospital of Air Force) between 2019 and 2022 was retrospectively analyzed. The pilots were grouped by the total CSVD score (0, 1, 2, 3, 4 points), and the distribution of CSVD imaging biomarkers was compared across groups. The severity of EPVS was classified into 3 levels: none or mild (0-10), moderate (11-20), and severe (>20). The impact of vascular risk factors on the total CSVD score and EPVS grading was analyzed.Results:The results of the total CSVD score showed that there were 19 cases (26.39%) with a score of 0, 43 cases (59.72%) with a score of 1, 10 cases (13.89%) with a score of 2, and 0 case with scores of 3 or 4. Among those who scored 1, there were 2 cases (4.65%) of lacunar infarction (LA), 1 case (2.33%) of moderate to severe white matter hyperintensity (WMH), 2 cases (4.65%) of cerebral microbleed (CMB), and 38 cases (88.37%) of moderate and severe EPVS. Among those who scored 2, there were 7 cases (70.00%) of LA combined with EPVS, 2 cases (20.00%) of CMB combined with EPVS, and 1 case (10.00%) of WMH combined with EPVS. According to the CSVD imaging classification of these pilots, there were 9 cases (12.50%) of LA, 52 cases (72.22%) of WMH, 4 cases (5.60%) of CMB and 61 cases (84.72%) of EPVS. Multiple ordered Logistic regression analysis showed that systolic blood pressure ( OR=1.068, 95% CI: 1.016-1.122) and high-density lipoprotein cholesterol ( OR=0.111, 95% CI: 0.015-0.843) made a difference in the total CSVD score. High-density lipoprotein cholesterol ( OR=0.166, 95% CI: 0.031-0.893) could affect the EPVS grading. Spearman′s correlation analysis showed that the systolic blood pressure level was positively correlated with the total CSVD score ( r=0.299, P=0.011), while the high-density lipoprotein cholesterol level was negatively correlated with the total CSVD score and EPVS grading ( r=-0.313, -0.263, P=0.041, 0.026). Conclusions:The total CSVD score of pilots is at a mild level with EPVS as the leading contributor. The systolic blood pressure and the high-density lipoprotein cholesterol level are determinants for the total CSVD score, while the high-density lipoprotein cholesterol level is a determinant for the EPVS grading of pilots. Blood pressure control and lipid regulation can go a long way towards preventing CSVD in pilots. The total CSVD score is of value for stratified evaluation and individual identification of pilots with CSVD.
