ObjectiveTo investigate the expression and activity of histone deacetylase (HDAC) in prostate cancer.Methodshe pathological samples of 37 cases of PCa were collected. The mean age of the patients was 73 (53 - 88 ) years, the preoperative t-PSA was 81.69 ( 3.13 - 2000 ) ng/ml, Gleason score: 13 cases were ≤7, 24 cases were >7. Twenty-seven cases of BPH were set as controls. The mean age of the BPH patients was 69 (52 - 84) years, the preoperative t-PSA was 10.93 ( 1.11 - 55.07 ) ng/ml.Western blotting and colorimetric Assay kits were used to determine the HDAC expression and activity. The difference of HDAC activity in benign prostatic hyperplasia and prostate cancer was statistically analyzed.The correlation of the HDAC expression level and values of PSA and Gleason score was also assessed.ResultsHDACs were over-expressed in most cases of prostate cancer, the expression rates were HDAC1 :57%, HDAC2: 68%, HDAC3: 84% and HDAC4: 73%, respectively. The HDAC activity (P <0.05)was significantly different between the prostate cancer and benign prostatic hyperplasia groups. The expression level of HDAC did not correlate with the values of PSA and Gleason score.ConclusionsHDAC was highly expressed and strongly active in prostate cancer. The results suggest that HDAC might be a potential target for the management of prostate cancer patients.

Objective To summarize the existing animal models of cholelithiasis,and to explore a pathological model that can better reflect the characteristics of clinical syndromes of traditional Chinese and western medicine and meet the needs of the development of clinical and basic research of traditional Chinese medicine. Methods The animal models for experimental research on cholelithiasis at home and abroad were collected and sorted out by searching CNKI,Wanfang,VIP,SinoMed,PubMed and other databases. The animal types,modeling methods,modeling cycles,detection indicators and positive drugs of the models were statistically analyzed. Results Among the 128 articles included,the animal types of cholelithiasis models were mainly guinea pigs,rabbits and C57BL/6J mice. The most used modeling method is high-fat diet,and the feeding cycle takes eight weeks to complete. High-frequency detection indicators were stone formation rate,total cholesterol,phospholipids,total bilirubin,total bile acid,etc. The commonly used intervention methods are traditional Chinese medicine compound,western medicine and single Chinese medicine or extract. Ursodeoxycholic acid (UDCA) is mainly used for western medicine intervention,whereas the intervention of traditional Chinese medicine mainly includes traditional Chinese medicine compound,acupuncture,exercise,diet and other methods. The positive control drug in the experiment was mostly UDCA. Conclusion With the continuous improvement and development of cholelithiasis animal model,there are many kinds of modeling methods to simulate the clinical manifestations of cholelithiasis in Chinese and western medicine,but there are also some limitations. This paper aims to provide reference for the selection,application and improvement of cholelithiasis model through data mining and characteristic analysis.

Metabolic-associated fatty liver disease (MAFLD) is a manifestation of multi-system metabolic dysfunction that affects the liver. Its disease spectrum not only includes fatty liver hepatitis, liver fibrosis, cirrhosis, liver malignancies, and other liver diseases but also includes extrahepatic diseases such as type 2 diabetes, atherosclerosis diseases, and chronic kidney disease. It is the most common chronic liver disease worldwide, with a complex pathogenesis and a lack of effective pharmacological treatments. With the improvement of people's living standards and the acceleration of the aging process, the incidence of MAFLD may continue to increase in the future, and its occurrence, development, prevention, and treatment have received widespread attention. Recent studies have shown that abnormal composition and proportion of gut microbiota can affect the changes in gut microbiota-derived metabolites. Metabolic disorders of bile acids and choline can further exacerbate gut microbiota imbalance, leading to a vicious cycle that destroys intestinal barrier function, increases intestinal permeability, and allows lipopolysaccharides, bacteria, viruses, and other substances to enter the liver through the ''gut-liver axis''. This process promotes liver inflammation and lipid deposition. Factors such as gut microbiota shift, regulation of host energy absorption, glucose and lipid metabolism, and inflammatory response interact to participate in the occurrence and development of MAFLD. Traditional Chinese medicine regulates the structure and function of gut microbiota through multiple targets, promoting the growth of beneficial bacteria, inhibiting the formation of harmful bacteria, restoring the balance of gut microbiota, improving intestinal mucosal barrier function, inhibiting liver inflammation and lipid degeneration, and influencing liver metabolism and immune response. This ultimately contributes to the prevention and treatment of MAFLD. This article systematically reviewed the mechanism of traditional Chinese medicine (TCM) treatment of MAFLD targeting gut microbiota through a literature search, aiming to provide ideas and references for TCM treatment of MAFLD.

The liver is closely associated with inflammation and the redox response, and inflammation is the body's innate defense system for clearing away harmful stimuli and participating in the liver's wound-healing response.Oxidative stress is associated with the activation of inflammatory pathways, and sustained inflammation and the corresponding regenerative wound healing response can induce fibrosis, cirrhosis, progression to end-stage liver disease or hepatocellular carcinoma, and ultimately death.Some "medicine and food homology" traditional Chinese medicine has been used in clinical effect, showing the ability to protect the liver.This paper reviewed the relationship between liver and oxidative stress response and inflammation response, and sorted out 110 "medicine and food same origin" traditional Chinese medicines based on the Chinese Pharmacopoeia(2020 edition) and the Chinese materia medica.The results showed that common floweringqince fruit, licorice root, cassia seed, emblic,seabuckthorn fruit,Chinese date, honeysuckle, ginger, cape jasmine fruit, platycodon root, lotus leaf, dandelion, reed root, honey, mountain honeysuckle, milkvetch root, glossy ganoderma, Gastrodia gastrodia and eucommia leaf were recorded to have liver protection effects.The liver protection mechanism is mainly anti-inflammatory, antioxidant and lipid peroxidation inhibition. Some Chinese herbs can also play a liver protection role by inhibiting the growth of hepatitis virus and liver cancer cells and regulating bile acid metabolism.In addition, the biological mechanism of its liver protection effect through antioxidant and anti-inflammatory effects in animal experiments was analyzed, and it was found that it plays a role through multiple pathways and multiple targets, providing new ideas for the role of "medicine and food homology" traditional Chinese medicine in the treatment strategy of liver diseases.

Saponins are widely found in various Chinese medicines such as Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma, and Bupleuri Radix. They possess multiple biological activities, including anti-inflammatory, antioxidant, antitumor, hepatoprotective, lipid-lowering, and hypoglycemic effects. They play an important role in the prevention and treatment of diseases such as acute lung injury, hyperlipidemia, and diabetic cardiovascular complications, and hold significant research potential and value. Metabolism-related fatty liver disease is a prevalent chronic liver disease characterized by excessive lipid accumulation in hepatocytes. According to the "multiple hit" theory, its occurrence is the result of systemic homeostasis disorder, influenced by abnormal lipid metabolism, oxidative stress, inflammation, insulin resistance, mitochondrial dysfunction, and intestinal microbiota. However, there is currently no effective treatment available in clinical practice. Recent studies have found that Chinese herbal saponins can alleviate metabolism-related fatty liver disease through various pathways, including regulating abnormal lipid metabolism, inhibiting inflammatory responses, alleviating oxidative stress, reducing insulin resistance, improving mitochondrial dysfunction, modulating intestinal flora, inhibiting hepatocyte programmed death, regulating liver autophagy, and correcting immune imbalances. Therefore, this review summarized the pharmacological effects and related mechanisms of Chinese herbal saponins in improving metabolism-related fatty liver disease in recent years, aiming to provide a theoretical reference for the clinical application and experimental research of Chinese herbal saponins in the prevention and treatment of metabolism-related fatty liver disease.

ObjectiveTo explore the macroscopic medication pattern of traditional Chinese medicine (TCM) in treating esophageal cancer (EC) and provide medication references for the clinical application of TCM in EC treatment. MethodRelevant literature on TCM treatment of EC was retrieved from three major Chinese databases: China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP. Information about Chinese herbal medicines was entered into Excel to establish a prescription database for EC. The data were standardized, summarized, and subjected to frequency analysis, association rules, and cluster analysis of medication in the prescriptions. Based on the TCM classification of EC syndromes, clinical indications corresponding to each syndrome were identified, and high-frequency drugs and drug pairs were analyzed correspondingly with syndromes. ResultA total of 136 prescriptions containing 240 Chinese herbal medicines were screened, with a cumulative frequency of 1 853 times. The top 5 frequently used Chinese herbal medicines were Glycyrrhizae Radix et Rhizoma, Poria, Atractylodis Macrocephalae Rhizoma, Astragali Radix, and Pinelliae Rhizoma. In terms of functions, the Chinese herbal medicines were mainly deficiency-tonifying, urination-promoting and dampness-draining, deficiency-tonifying, deficiency-tonifying, and phlegm-resolving and cough and dyspnea-relieving ones. The statistical analysis of flavor, property, and meridian tropism showed that Chinese herbal medicines were mainly bitter and sweet, warm, cold, and neutral, and acted on the spleen, lung, and stomach meridians. Association rule analysis yielded nine potential drug combinations, and cluster analysis of high-frequency drugs resulted in four combination categories. The four TCM syndromes for EC corresponded to respective clinical indications, treatment drugs, and drug pairs. ConclusionTonifying deficiency, reinforcing healthy Qi, descending adverse Qi, resolving phlegm, activating blood, and resolving stasis are the basic principles of TCM treatment for EC, which are supplemented by clearing heat and dissipating mass while focusing on regulating and smoothing the qi movement. The drug combinations obtained from high-frequency drug and association rule analysis provide references for different TCM syndrome treatments of EC, offering valuable insights for clinical medication.
