Acute pancreatitis (AP) is a severe inflammatory disease characterized by self-digestion of pancreatic tissue and inflammatory responses. Recent studies have revealed a close connection between gut microbiota and AP. The gut microbiota community, a complex ecosystem composed of trillions of microorganisms, is closely associated with various physiological activities of the host, including metabolic processes, immune system regulation, and intestinal structure maintenance. However, in patients with AP, dysbiosis of the gut microbiota are believed to play a key role in the occurrence and progression of the disease. This dysbiosis not only impairs the integrity of the intestinal barrier, but may also exacerbate inflammatory responses through multiple mechanisms, thereby affecting the severity of the disease and patient' clinical prognosis. This article reviews the mechanisms of action of gut microbiota in AP, explores how gut microbiota dysbiosis affects disease progression, and evaluates current clinical treatment methods to regulate intestinal flora, including probiotic supplementation, fecal microbiota transplantation, antibiotic therapy, and early enteral nutrition. In addition, this article discusses the efficacy and safety of the aforementioned therapeutic approaches, and outlines future research directions, aiming to provide novel perspectives and strategies for the diagnosis, treatment and prognostic evaluation of AP. Through in-depth understanding the interaction between gut microbiota and AP, it is expected that more precise and personalized therapeutic regimens will be developed to improve patients' quality of life and clinical outcomes.

Objective To investigate the influencing factors for stroke-associated pneumonia(SAP)in acute ischemic stroke(AIS)patients after endovascular treatment(EVT).Methods A retrospective case-control trial was conducted on 426 AIS patients with large vessel occlusion(LVO)in anterior circulation admitted in the neurological departments from First Affiliated Hospital of Army Medical University and Zigong Third People's Hospital during January 2017 and April 2021.Based on SAP occurrence or not,they were divided into an SAP group and a non-SAP group.Demographic information(gender and age),TOAST stroke subtypes(large artery atherosclerosis type,cardiac embolism type,others),vascular risk factors(hypertension,hyperlipidemia,diabetes,atrial fibrillation,smoking,prior stroke history,smoking),and post-onset clinical data[dysphagia,LDL cholesterol,white blood cells,neutrophils,baseline and postoperative NIHSS scores,endovascular outcomes(mTICI grade 2b or 3),90-day good prognosis(mRS 0-1)]were collected and compared between the 2 groups.Multivariate logistic regression analysis was performed using the parameters with P<0.1 in univariate analysis as independent variables to investigate factors influencing SAP occurrence after EVT in AIS patients.Results Among the 426 participants,SAP occurred in 194 cases(45.5%).Multivariate logistic regression analysis revealed that admission white blood cell count(OR=1.125,95%CI:1.043～1.213,P=0.000 2),postoperative NIHSS score(OR=1.019,95%CI:1.001～1.037,P=0.041),and male(OR=1.687,95%CI:1.078～2.638,P=0.022)were associated with SAP occurrence after EVT in AIS patients.Conclusion Higher admission white blood cell count,elevated postoperative NIHSS score,and male gender are risk factors for SAP in AIS patients after EVT.These risk factors should be focused on clinical practice to control SAP incidence.

Stroke is a neurological disease characterized by cerebral ischemia or hemorrhagic injury， leading to death and disability worldwide. At present， there is still a lack of neuroprotective drugs for the treatment of stroke. Niuhuang Qingxin pills are Chinese patent medicine recommended by guidelines and expert consensus for preventing and treating stroke. Studies have shown that Niuhuang Qingxin pills have sedative， anticonvulsant， antipyretic， and other pharmacological effects. Moreover， the main components， such as flavonoids， phenolic acids， and saponins， also exhibit strong pharmacological activities which can improve stroke-induced nerve damage. Studies have confirmed that representative ingredients such as baicalin and ginsenosides can interfere with multiple pathological events， including blood-brain barrier destruction， oxidative stress， inflammatory response， apoptosis， and autophagy， and the mechanisms of the essential ingredients are related to the action on important targets such as Kelch-like ECH-associated protein 1 （Keap1）， matrix metalloproteinase-9 （MMP-9）， and high-mobility group box 1 （HMGB1）， and involvement in the regulation of Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB）， nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1）， and phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathways. This article summarized the research status of Niuhuang Qingxin pills and the experimental pharmacological progress of common ingredients in the prevention and treatment of stroke to provide clues for further research into Niuhuang Qingxin pills and the development of active ingredients of traditional Chinese medicines.

With the rapid development of social economy， the number of patients with nervous system diseases has increased， and the incidence of the population has a trend of younger， which has a serious impact on life health and social economy. Artemisinin is an active antimalarial component extracted and isolated from Artemisia annua， a Chinese medicinal material. Artemisinin and its derivatives， in addition to the antimalarial effect， also have anti-parasitic， anti-fungal， anti-viral， hypoglycemic， hypolipidemic， anti-tumor， and anti-inflammatory effects， showing a wide range of pharmacological activities. In the past five years， research on the new pharmacological effects of artemisinin and its derivatives has been deepening， and the efficacy of artemisinin and its derivatives in nervous system diseases has attracted much attention， including anti-neuroinflammation， anti-oxidative stress， maintaining the stability of the blood-brain barrier， regulating the release of neurotransmitters， repairing neuronal damage， and promoting neuronal regeneration. These pharmacological effects indicate that artemisinin and its derivatives are potentially capable of neuroprotection. By sorting out literature on the pharmacological activity of artemisinin and its derivatives in nervous system during 2019－2024， this paper systematically summarized the protective effects of artemisinin and its derivatives against nervous system diseases such as stroke， neurodegenerative diseases， neuroimmunological diseases， neuralgia， and nervous system tumors. This review is expected to provide clues and evidence for new indication expansion of artemisinin drugs， innovative drug development， and clinical treatment of nervous system diseases.

The impact of air pollution on human health has always been a research hotspot in the global health field. Outdoor air pollutants composed of multiple components can enter the human body through various pathways. Cardiovascular diseases are a group of diseases caused by outdoor air pollutants. Studies have shown that the incidence of cardiovascular diseases， including hypertension， arrhythmia， and heart failure， is significantly increased among people exposed to air pollution environments. Air pollutants such as fine particulate matter， nitrogen dioxide， ozone， carbon monoxide， and sulfur dioxide are closely related to the occurrence of cardiovascular diseases， and short-term and long-term exposure causes different cardiovascular risks. By reviewing the relevant research reports from 2019 to 2024， this article summarizes the epidemiological evidence of cardiovascular diseases caused by different air pollutants. It generalizes the pathways through which air pollutants accelerate the progression of cardiovascular diseases. These pathways include oxidative stress， inflammatory response， thrombosis， extracellular vesicle release， endoplasmic reticulum stress， apoptosis， endothelial dysfunction， autonomic nervous system imbalance， and their interactions. Based on the different mechanisms of air pollution on cardiovascular diseases， the article analyzes the main progress in drug intervention and summarizes the roles of various active ingredients and compound prescriptions of traditional Chinese medicine in treating air pollution-related cardiovascular diseases， providing reference for the research on the mechanisms and drug interventions of air pollution-related cardiovascular diseases.

The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated， becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist （GLP1-RA） and sodium glucose cotransporter-2 inhibitors （SGLT2） are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports， this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases （e.g.， hyperglycemia， insulin resistance， and inflammation）， related targets such as apolipoprotein C-Ⅲ （APOC3）， S100 calcium-binding protein A8/A9 （S100A8/A9）， growth/differentiation factor-15 （GDF-15）， and NACHT， LRR， and PYD domains-containing protein 3 （NLRP3）， advanced glycation end products， insulin resistance， endothelial dysfunction， endoplasmic reticulum stress， mitochondrial dysfunction， and intestinal flora disorder. In addition， this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients （e.g.， baicalein， puerarin， curcumin， notoginsenoside， and tanshinone Ⅱ_A）， single herbal medicines （e.g.， Astragali Radix， Ginseng Radix et Rhizoma， Sophorae Flavescentis Radix， Cinnamomi Cortex， and Corni Fructus）， and compound formulas （e.g.， Buzang Tongluo Fang， Yiqi Yangyin Huoxue Fang， Shenqi Fang， Huangqisan， Danggui Buxue Tang， and Liuwei Dihuang Wan） of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress， ameliorating dyslipidemia and insulin resistance， protecting islet β cell function， repairing endothelial damage， inhibiting smooth muscle cell proliferation， foam cell formation， macrophage polarization， and cardiac hypertrophy and fibrosis， and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B （IRS/PI3K/Akt）， peroxisome proliferator-activated receptor α/γ （PPAR α/γ）， nuclear factor-kappa B （NF-κB）， adenosine 5′-monophosphate （AMP）-activated protein kinase （AMPK）， hypoxia-inducible factor-1-BCH domain-containing protein （HIF-1-BNIP）， vascular endothelial growth factor/hypoxia-inducible factor-1α （VEGF/HIF-1α） and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.

Preoperative neoadjuvant chemoradiotherapy, combined with total mesorectal excision, has become the standard treatment for advanced localized rectal cancer (RC). However, the biological complexity and heterogeneity of tumors may contribute to cancer recurrence and metastasis in patients with radiotherapy-resistant RC. The identification of factors leading to radioresistance and markers of radiosensitivity is critical to identify responsive patients and improve radiotherapy outcomes. MicroRNAs (miRNAs) are small, endogenous, and noncoding RNAs that affect various cellular and molecular targets. miRNAs have been shown to play important roles in multiple biological processes associated with RC. In this review, we summarized the signaling pathways of miRNAs, including apoptosis, autophagy, the cell cycle, DNA damage repair, proliferation, and metastasis during radiotherapy in patients with RC. Also, we evaluated the potential role of miRNAs as radiotherapeutic biomarkers for RC.
