Objective To analyze the case data of farmers' foodborne disease surveillance reports in Guizhou Province from 2022 to 2024, and to provide reference for the precise prevention and control of foodborne diseases among farmers in Guizhou Province. Methods Case data of foodborne disease surveillance reports of farmers were systematically collected from 2022 to 2024 in Guizhou Province. Descriptive epidemiological methods were used to analyze the temporal, geographical, and demographic distribution of foodborne diseases among farmers, along with their primary clinical symptoms and pathogen detection results. Results From 2022 to 2024, a total of 22,882 cases of foodborne diseases were reported among farmers in Guizhou Province. The majority of clinical symptoms (97.81%) were related to the digestive system, with summer being the peak season. While females outnumbered males, the gender difference was statistically insignificant (P >0.05). The 36-55 age group accounted for the highest proportion (38.83%), with Zunyi City (34.89%) and Qiandongnan Prefecture (23.21%) reporting the most cases. Fungal products were the most frequently reported suspected food items (26.96%), and home-made preparation was the primary processing method (58.63%). A total of 1 210 fecal samples were collected through active monitoring with an overall detection rate of 13.22%. Norovirus showed the highest detection rate (9.92%, 120/1 210). Statistically significant differences were observed among different seasons, age groups, regions, types and processing methods of suspected food exposure, and pathogen detection rates (P <0.001). Conclusion Foodborne disease prevention and control among farmers in Guizhou Province should focus on the risks of wild mushroom poisoning in summer and homemade foods, and continuously improve farmers' awareness of the dangers of foodborne diseases and food safety.

ObjectiveTo investigate the effects of salidroside (SAL) on the impaired bioactivity of endothelial progenitor cells (EPCs) in atherosclerotic (As) mice and the potential mechanisms regarding AMP-activated protein kinase (AMPK). MethodsAtherosclerosis was induced in 8-week-old male ApoE-/- mice with high-fat diet. Intragastric administration of SAL was given to one mice group to investigate the effects of SAL on aortic plaque burden, plasma NO level, the migration and angiogenic capabilities of bone marrow-derived EPCs (BM-EPCs). The proliferation, migration and vasculogenic properties of EPCs isolated from As mice were investigated in vitro. AMPK-sh-RNA or the AMPK inhibitor Compound C was used to investigate the role of AMPK/Akt/eNOS pathway in the regulatory effects of SAL. ResultsCompared with As group, NO level was significantly elevated in SAL group. The sizes of atherosclerotic plaques at the aortic root were reduced with smaller lipid cores in SAL group compared with As group. Moreover, the migration and angiogenesis capacity of EPCs markedly decreased in As mice, while SAL treatment reversed these impairments. Incubation with SAL at concentrations of 20, 40, and 80 μmol/L for 48 hours significantly promoted the proliferation, migration, and angiogenesis of EPCs. AMPK-sh-RNA transfection abrogated the 20 μmol/L SAL improvement in EPC biological activities. Western blot analysis further demonstrated that treatment with Compound C blocked the activation of AMPK/Akt/eNOS signaling pathway induced by SAL. ConclusionSAL upregulates the biological functions of EPCs through activating the AMPK/Akt/eNOS signaling pathway, thereby ameliorating EPC dysfunction during the pathological progression of atherosclerosis.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).

OBJECTIVE To investigate the mechanism of Shenling baizhu san (SLBZS) in ameliorating ulcerative colitis (UC). METHODS Mice were randomly divided into normal group, model group, and low-, medium-, high-dose SLBZS groups (3, 6, 12 g/kg), with 10 mice in each group. Except for the normal group, mice in other groups were given free access to 3% dextran sulfate sodium solution for 7 days to establish UC models. Simultaneously, mice in each group were intragastrically administered corresponding medicinal liquid or double-distilled water once a day for consecutive 7 days. After the last administration, the histopathological morphology of colon tissues was observed; the serum levels of inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-18 were detected; the total bile acid contents in liver, gallbladder and colon tissues were determined; the expression level of NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) in colon tissues was tested. The expression levels of flora metabolism-related proteins [G protein-coupled receptor 41(GPR41),GPR43,farnesoid X receptor (FXR), G protein-coupled bile acid receptor 1 (TGR5), flavin-containing monooxygenase 3 (FMO3), cytochrome P450 family 27 subfamily A member 1 (CYP27A1), CYP7A1] in liver or colon tissues, as well as the proteins related to Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB)/NLRP3 inflammatory axis [TLR4, NF-κB, phosphorylated NF-κB (p-NF-κB), myeloid differentiation factor 88 (MyD88), NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1] in colon tissues were measured. RESULTS Compared with the model group, the colon tissue injury and inflammatory cell infiltration were alleviated in medium- and high-dose SLBZS groups. The serum levels of TNF-α, IL-1β and IL-18, total bile acid contents in liver and colon tissues, as well as the protein expression levels of FMO3 and CYP7A1 in liver tissues, TLR4, p-NF-κB, NF-κB, MyD88, NLRP3, ASC and caspase-1 in colon tissues were significantly decreased (P<0.05). Meanwhile, the total bile acid content in gallbladder, the protein expression levels of GPR41 and GPR43 in colon tissues, along with CYP27A1, FXR and TGR5 in liver tissues were significantly increased (P<0.05). CONCLUSIONS SLBZS may relieve colonic inflammatory injury and ameliorate UC by regulating the expression of flora metabolism-related proteins and inhibiting the abnormal activation of TLR4/NF-κB/NLRP3 inflammatory axis.

ObjectiveType 2 diabetes mellitus (T2DM) often causes severe hepatic metabolic complications, dominated by metabolic associated fatty liver disease (MAFLD). Persistent hepatic steatosis and oxidative stress further trigger steatohepatitis and progressive liver damage, increasing the mortality risk of diabetic patients. Aerobic exercise effectively improves hepatic lipid metabolism and antioxidant capacity, but poor patient adherence restricts its long-term clinical application. Mitochondrial-derived mitochondrial open reading frame of the 12S rRNA type-c (MOTS-c) is a key peptide regulating insulin sensitivity and hepatic redox homeostasis. This study aimed to explore the protective mechanism of MOTS-c against T2DM-related liver injury and its combined beneficial effect with aerobic exercise via the NRF2/PPARγ signaling axis. This study aimed to investigate whether MOTS-c cooperates with aerobic exercise to alleviate T2DM-associated hepatic oxidative stress and metabolic dysfunction by activating the NRF2/PPARγ axis, and to clarify the molecular and transcriptomic characteristics of their combined intervention. MethodsStable MOTS-c overexpression and knockdown HepG2 cell lines were constructed using lentiviral transfection. An oleic acid-induced cellular lipid accumulation model and NRF2-knockout cell model were applied to verify the NRF2-dependent mechanism ofMOTS-c. Intracellular lipid deposition, triglyceride levels, antioxidant enzyme activities, and the expression of NRF2/PPARγ pathway-related genes and proteins were detected. In vivo, a T2DM rat model with obvious hepatic steatosis was established via a high-fat and high-sucrose diet combined with streptozotocin injection. Model rats received aerobic exercise, MOTS-c intraperitoneal injection, or combined intervention. We detected systemic glycolipid metabolic indicators, hepatic histopathological changes, and the expression of core proteins in the hepatic NRF2/PPARγ axis. Hepatic transcriptomic sequencing was performed to screen differentially expressed genes (DEGs) and enrich key pathways co-regulated by MOTS-c and aerobic exercise. ResultsCellular results showed that MOTS-c overexpression significantly reduced oleic acid-induced lipid deposition, enhanced antioxidant enzyme activity, and upregulated NRF2 and PPARγ expression. Conversely, MOTS-c knockdown aggravated hepatic lipid accumulation and oxidative damage and inhibited NRF2/PPARγ pathway activation. NRF2 knockout completely eliminated the protective effects of MOTS-c on lipid metabolism and redox balance, confirming its NRF2-dependent regulatory mechanism. In T2DM rats, both MOTS-c supplementation and aerobic exercise effectively improved insulin resistance, corrected glycolipid metabolic disorders, and alleviated hepatic steatosis, while consistently activating the hepatic NRF2/PPARγ axis. Compared with single intervention, the combined treatment showed a better improvement trend in hepatic metabolic and oxidative injury, without definitive synergistic effects. Transcriptomic analysis revealed that the co-regulated DEGs of MOTS-c and aerobic exercise were primarily enriched in lipid metabolism and PPAR signaling pathways, with multiple antioxidant and lipid-regulating genes significantly modulated by combined intervention. ConclusionMOTS-c exhibits obvious exercise-mimetic hepatoprotective effects in T2DM. It activates the hepatic NRF2/PPARγ axis to strengthen antioxidant defense, stabilize lipid metabolism, and relieve T2DM-associated hepatic steatosis and oxidative damage. Furthermore, MOTS-c produces additive beneficial effects with aerobic exercise, showing a superior intervention trend on diabetic liver dysfunction. This study identifies the NRF2/PPARγ axis as the core mechanism of MOTS-c-regulated hepatic protection, elucidates the transcriptomic basis of combined intervention, and provides a reliable theoretical basis and potential therapeutic target for clinical intervention in T2DM-complicated MAFLD.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most prevalent chronic liver disease worldwide, with a complex pathogenesis. Mitochondria play a pivotal role in this disease process, and studies have confirmed that mitochondrial dysfunction can exacerbate metabolic disorders and induce innate immune imbalance, while mitochondrial DNA (mtDNA) is the core molecule mediating these two pathological effects. After the abnormal release of mtDNA, it can be recognized by intracellular pattern recognition receptors, which in turn triggers innate immune responses and causes tissue damage, forming a pathological pathway of “mtDNA release-immune activation-tissue damage”. Currently, there is a lack of systematic reviews summarizing the mechanism of action of this pathway in different stages of MAFLD and the intervention strategies targeting this pathway. This article systematically reviews the core molecular mechanism of this pathway, its pathological role in the development and progression of MAFLD, and the current intervention strategies targeting this mechanism, in order to provide a theoretical basis for analyzing the pathogenesis of MAFLD and developing novel therapeutic strategies.

The theory of "Yang transforming Qi while Yin constituting form" in the Huangdi's Internal Classic is derived from the application, transformation, movement, and balance of Tao. It is highly condensed, revealing the true meaning of Tao and guiding the changes and progress of all natural things, including diseases. Therefore, the appearance of various physical diseases is the manifestation of Yin-Yang Qi transformation. Sweat pore, formed by the Qi transformation of Yin and Yang, is the nourishing and regulating system. It serves as the hub and channel, assisting in the flow and transformation of Qi, facilitating the exchange of material, energy, and information with the outside world. With sweat pore as the hub and based on the macro-control and holistic thinking of "Yang transforming Qi while Yin constituting form", this paper explores the microscopic mechanisms underlying chronic liver disease. In combination with the roles of mitochondria, exosomes, and the ultraliver sieve structure in the formation and progression of chronic liver disease, this paper elucidates the close internal relationship between the disease's initial quality, symptom signs, and its physiological and pathological functions under the guidance of this theory. Modern studies have shown that autophagy, intestinal flora disorders, glucose and lipid metabolism disturbances, activation of inflammatory factors, ferroptosis, and other microscopic pathological mechanisms are involved in the occurrence and development of chronic liver disease. The common connotation of the Yin-Yang concept in traditional Chinese medicine (TCM) and the pathological mechanisms in modern medicine is deeply analyzed. The corresponding relevant microscopic mechanisms and the guiding role of the theory of "Yang transforming Qi while Yin constituting form-sweat pore" in the management of chronic liver disease are summarized. Wind medicine promotes growth and transformation through sweat pore. The combination of pungent and sweet medicines facilitates Yang and disperse Yin. The formulas, combining the characteristics of wind medicine and pungent and sweet medicines, fit the principle of "Yang transforming Qi while Yin constituting form-sweat pore". This paper combines both macro and micro perspectives to explain the scientific connotation and microscopic mechanisms of chronic liver disease based on the theory of "Yang transforming Qi while Yin constituting form-sweat pore", and explore the prevention and treatment of chronic liver disease through the principles, methods, prescriptions, and medicines featured by combination of pungent and sweet medicines, facilitating Yang, activating sweat pore, and dispersing Yin, providing new ideas and reference for the clinical treatment of chronic liver disease.
