With the improvement of living standards， the incidence rate of metabolic dysfunction-associated fatty liver disease （MAFLD） is gradually increasing with a younger age of onset， and MAFLD has become a global health problem， while its specific pathogenesis remains unclear. Macrophages， as one of the important cells involved in the pathogenesis of MAFLD， have the ability to present antigens， eliminate pathogenic microorganisms， and promote liver inflammatory responses， thereby attracting wide attention for a long time. The latest studies have shown that macrophages may become a new therapeutic target for MAFLD. This article systematically reviews the role of intrahepatic macrophages in liver inflammation caused by MAFLD， including their activation， polarization， recruitment mechanisms， and interactions with other cells， in order to provide new ideas and perspectives for the clinical prevention and treatment of MAFLD.

Objective To discuss the application of bidirectional dual loop technique in retrieving Aegisy inferior vena cava filters.Methods The clinical data of 12 patients with deep vein thrombosis in the lower limbs complicated by pulmonary embolism,who received mechanical thrombectomy and Aegisy inferior vena cava(IVC)filter implantation at the Zhoukou Municipal Central Hospital of China from January 2016 to November 2023,were retrospectively analyzed.The retrieval of Aegisy IVC filters beyond the time window was tried by standard methods,guide wire stripping,balloon dilatation,unidirectional single loop technique,unidirectional dual loop technique,etc.However,because of the difficulty in retrieval of filter,bidirectional dual loop technique had to be used.The indwelling time of the IVC filters was 30-365 days,with an average time of 105 days.Results The IVC filter was completely removed in 11 patients.Angiography showed that IVC was unobstructed,no contrast extravasation was observed,and the average operation time was 126 minutes.The retrieval of filter failed in one patient,and the patient had to receive anticoagulation therapy lifelong.No surgery-related complications occurred.Conclusion For retrieving Aegisy IVC filters beyond the time window,bidirectional dual loop technique is clinically safe and effective,and this technology is worthy of clinical promotion and application.

AIM To investigate the effects of rice wine type and wine processing method on chemical constituents and anti-coagulation effect of Angelicae sinensis Radix.METHODS Wine-washed products and wine-stir-fried products were prepared by different types and ages of rice wine,respectively,after which HPLC was adopted in the content determination of tryptophan,chlorogenic acid,vanillic acid,phthalic acid,ferulic acid,senkyunolide I,senkyunolide H,coniferyl ferulate and ligustilide,and PT,APTT,TT were detected in rabbit plasma.RESULTS Phenolic acids and volatile constituents demonstrated lower contents in the wine-stir-fried products than those in the raw product(P＜0.05),while those in the wine-washed products displayed no obvious changes(except for senkyunolide I)(P＞0.05).The contents of volatile constituents in the wine-washed products were higher than those in the wine-stir-fried products(P＜0.05).After being processed with dry rice wine,various constituents exhibited increased contents as compared with those after being processed with sweet rice wine(P＜0.05).Compared with the raw product,prolonged PT,APTT and TT were observable in the processed products prepared by 3-year semi-dry rice wine(P＜0.05).CONCLUSION The optimal rice wine type is determined to be 3-year semi-dry.Wine-washed Angelicae sinensis Radix shows high contents of ferulic acid and volatile constituents,whose activating blood and resolving stasis effect may be stronger.

This paper aims to study the effect of p-cymene on mice with deficiency-cold syndrome induced by hydrocortisone and deficiency-heat syndrome induced by dexamethasone and explore the medicinal properties and mechanism of p-cymene with mild and warm nature based on the dominant characteristics of the two-way applicable conditions of mild drugs. A total of 80 KM mice were randomly divided into blank group, deficiency-cold syndrome model group, deficiency-cold syndrome + ginseng group, and deficiency-cold syndrome + low-dose and high-dose p-cymene groups, as well as blank group, deficiency-heat syndrome model group, deficiency-heat syndrome + American ginseng group, and deficiency-heat syndrome + low-dose and high-dose p-cymene groups. Hydrocortisone and dexamethasone solution were intragastrically administered for 14 consecutive days to prepare deficiency-cold syndrome and deficiency-heat syndrome models. Except for the blank group and the model group intragastrically administered with normal saline, the other groups were intragastrically administrated with drugs for 14 days. The levels of cyclic adenosine monophosphate(cAMP), cyclic guanosine monophosphate(cGMP), triiodothyronine(T3), thyroxine(T4), total cholesterol(TC), triglyceride(TG), immunoglobin G(IgG), and immunoglobin M(IgM) in serum, as well as the activity of Na~+-K~+-ATPase in liver tissue were detected. The expression of transient receptor potential melastatin 8(TRPM8), transient receptor potential vanilloid 1(TRPV1), and uncoupling protein 1(UCP1) in brown adipose tissue of deficiency-cold syndrome model after intervention with p-cymene was studied. The results showed that p-cymene could effectively improve the levels of cAMP, cAMP/cGMP, TC, IgM, and IgG in serum and the activity of Na~+-K~+-ATPase in liver tissue of mice with deficiency-cold syndrome and reduce the content of cGMP. The effects on T3, T4, and TG were not statistically significant. At the same time, p-cymene could reduce the levels of cAMP, cAMP/cGMP, and T4 in serum and the activity of Na~+-K~+-ATPase in liver tissue of mice with deficiency-cold syndrome and increase the levels of cGMP, IgM, and IgG, and it had no effect on T3, TC, and TG. In addition, p-cymene could up-regulate the expression of TRPV1 and UCP1 in brown fat of mice with deficiency-cold syndrome and down-regulate the expression of TRPM8. In summary, p-cymene could significantly regulate the syndrome indexes of mice with deficiency-cold syndrome, and some indexes of mice with deficiency-heat syndrome could be improved, but the effects on lipid metabolism and energy metabolism indexes were not obvious, indicating that the regulation effect of p-cymene on deficiency-cold syndrome model was more prominent and that the medicinal properties of p-cymene were mild and warm. The regulation of TRPV1/TRPM8/UCP1 channel expression may be the molecular biological mechanism of p-cymene with mild and warm nature affecting the energy metabolism of the body.

Objective: To investigate the value of decreased carbohydrate antigen 19-9(CA19-9) kinetics in predicting short-term outcomes and determining prognosis among advanced biliary or pancreatic cancer patients receiving first-or second-line therapy in the real world. Methods : Eighty-nine patients were retrospectively collected with advanced biliary or pancreatic cancer, especially on the CA19-9 dynamics and decline rates at different time points. This study evaluated the association of CA19-9 changes with clinicopathological features, short-term response to antitumor therapy, and survival outcomes. Results : The enrolled patients recorded baseline CA19-9 levels ranging from 1.20 to 65 706.40 U/ml, with a median of 303.11 U/ml. There was no statistical correlation between baseline CA19-9 levels and gender, age, body mass index, primary tumor site, hepatic metastases, pulmonary metastases, lymph node metastases, peritoneal metastases, performance status, treatment lines, and combinations of drug types. Baseline CA19-9 levels were not associated with systemic immunoinflammatory index, prognostic nutritional index, and total bilirubin. A 25% or 50% decrease in CA19-9 after 2-3 therapy courses indicated short-term efficacy in reaching tumor objective remission or disease control. Both combinations of multiple drug types and a 25% decline in CA19-9 after one course of treatment were independent prognostic factors that affected the longer progression-free survival of patients receiving first or second line of treatment. Conclusion Decreased CA19-9 kinetics has specific values in predicting the efficacy and prognosis of advanced biliary or pancreatic cancer.

As global greenhouse gases continue rising, the urgency of more ambitious action is clearer than ever before. China is the world's biggest emitter of greenhouse gases and one of the countries affected most by climate change. The evidence about the impacts of climate change on the environment and human health may encourage China to take more decisive action to mitigate greenhouse gas emissions and adapt to climate impacts. This article aimed to review the evidence of environmental damages and health risks posed by climate change and to provide a new science-based perspective for the delivery of sustainable development goals. Over recent decades, China has experienced a strong warming pattern with a growing frequency of extreme weather events, and the impacts of climate change on China's environment and human health have been consistently observed, with increasing O ₃ air pollution, decreases in water resources and availability, land degradation, and increased risks for both communicable and non-communicable diseases. Therefore, China's climate policy should target the key factors driving climate change and scale up strategic measures to curb carbon emissions and adapt to inevitable increasing climate impacts. It provides new insights for not only China but also other countries, particularly developing and emerging economies, to ensure climate and environmental sustainability whilst pursuing economic growth.

Organic ultraviolet absorbers (OUVs) have been widely used in personal care products and industrial products due to their unique physicochemical properties. However, with the advancement of science and technology and the deepening of research, the potential risks of OUVs have gradually emerged. They have been proven to be persistent, bioconcentrated and potential endocrine disruptors that may pose a threat to human health. In recent years, some OUVs have been widely detected in environmental and human samples worldwide, and the concentration of detection has been increasing year by year, which has attracted extensive attention both domestically and internationally. This article summarizes the research results of OUVs exposure in recent years from two aspects: external environmental exposure and internal human exposure, aiming to provide a valuable reference for the subsequent research on human exposure and health risk assessment of OUVs.
