ObjectiveTo explore the mechanism by which Yinchenhao Tang intervenes in α-naphthylisothiocyanate (ANIT)-induced cholestatic liver injury by regulating the Takeda G-protein-coupled receptor 5(TGR5)/NOD-like receptor protein 3(NLRP3)/cysteine aspartate-specific protease-1 (Caspase-1) pyroptosis signaling pathway. MethodsForty male Wistar rats were randomly assigned into blank, model, ursodeoxycholic acid, and Yinchenhao Tang groups. Except the blank group, other groups were treated with ANIT dissolved in olive oil for the modeling of cholestatic liver injury. Ursodeoxycholic acid (0.1 g·kg-1) and Yinchenhao Tang (9.23 g·kg-1) were administered by gavage. The blank group and the model group were administrated with the same amount of pure water, once a day for 3 days. The blood and liver tissue samples were collected, and the serum levels of liver function indicators were measured by an automatic biochemical analyzer. Hematoxylin-eosin staining was employed to observe the pathological changes of the liver. The levels of interleukin (IL)-1β and IL-18 in the liver tissue were determined by ELISA. The mRNA levels of IL-1β, IL-18, TGR5, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, and GSDMD in the liver tissue were assessed by Real-time PCR. The protein levels of TGR5, NLRP3, ASC, Caspase-1, and GSDMD in the liver tissue were determined by Western blot. ResultsCompared with the blank group, the model group showed elevated levels of alanine amino-transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), total bile acid (TBA), and total bilirubin (TBil) in the serum (P<0.01), inflammatory cell infiltration, hepatocyte swelling, and bile duct epithelial cell proliferation in the liver, raised levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA and protein levels of TGR5 (P<0.01), up-regulated mRNA levels of IL-18 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), IL-1β (P<0.05), and NLRP3 (P<0.05), and up-regulated protein levels of NLRP3 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), and GSDMD (P<0.05). Compared with the model group, the ursodeoxycholic acid group showed declined levels of AST (P<0.01), TBA (P<0.01), TBil (P<0.01), and ALT (P<0.05) in the serum, lowered levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA levels of NLRP3 (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), IL-1β (P<0.05), IL-18 (P<0.05), and ASC (P<0.05), up-regulated mRNA and protein levels of TGR5 (P<0.05), and down-regulated protein levels of NLRP3, ASC, Caspase-1, and GSDMD (P<0.05). Compared with the model group, the Yinchenhao Tang group showed lowered levels of ALT, AST, ALP, TBA, and TBil in the serum (P<0.01), declined levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA levels of IL-1β (P<0.01), NLRP3 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), and IL-18 (P<0.05), up-regulated mRNA and protein levels of TGR5 (P<0.01), and down-regulated protein levels of Caspase-1 and GSDMD (P<0.05). The liver tissue of the administration groups showed reduced infiltration of inflammatory cells, reduced swelling of hepatocytes, and alleviated proliferation of bile duct epithelial cells. ConclusionYinchenhao Tang can ameliorate ANIT-induced cholestatic liver injury by regulating the hepatocyte pyroptosis mediated by the TGR5/NLRP3/Caspase-1 signaling pathway.

ObjectiveThis study aims to investigate the mechanism of Yinchenhao Tang (YCHT) in regulating macrophage polarization to alleviate cholestatic liver injury,focusing on the TLR4/NF-κB signaling pathway as the entry point. MethodsCholestasis was induced in Wistar rats through a single gavage of 100 mg·kg-1 α-naphthyl isothiocyanate (ANIT) dissolved in olive oil. The animals were randomly divided into four groups:Model group,YCHT group,ursodeoxycholic acid (UDCA) group (n=10),and a blank group (n=10) that received only 5 mL·kg-1 olive oil. The YCHT group received 9.23 g·kg-1·day-1 of YCHT by gavage,and the UDCA group was treated with 0.1 g·kg-1·day-1 of UDCA suspension. Both the normal and model groups were given an equal volume of normal saline,all for three consecutive days. Serum liver function was assessed using an automatic biochemical analyzer. Hematoxylin-eosin (HE) staining was used to observe liver tissue morphology. Levels of tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β),transforming growth factor-β (TGF-β),and interleukin-10 (IL-10) were quantified in liver homogenate supernatants via enzyme-linked immunosorbent assay (ELISA). Western blot analysis measured the relative protein expression of Toll-like receptor 4 (TLR4),nuclear factor-κB (NF-κB),CD206,inducible nitric oxide synthase (iNOS), CD86,and arginase-1 (Arg-1). The relative mRNA expression of TLR4/NF-κB,CD206,iNOS,CD86,and Arg-1 in liver tissue was evaluated using real-time quantitative PCR. ResultsCompared with the normal group,the model group exhibited significantly elevated levels of alkaline phosphatase (ALP),total bile acid (TBA),total bilirubin (TBil),aspartate aminotransferase (AST),and alanine aminotransferase (ALT) (P<0.01). There was a portal area expansion and pronounced inflammatory cell infiltration. The expression of pro-inflammatory markers TNF-α and IL-1β was significantly upregulated (P<0.01),and macrophage markers CD86 and CD206 showed positive expression. Protein and mRNA expressions of iNOS and CD86 were significantly elevated (P<0.01). The mRNA and protein expressions of the related pathway molecules TLR4 and NF-κB were significantly increased (P<0.01). Compared with those in the model group, the liver function indicators in the YCHT group showed significant decreases (P<0.05, P<0.01). The bile duct hyperplasia was significantly alleviated, and the tissue structure became more orderly. The levels of IL-1β and TNF-α were significantly reduced (P<0.01), while the expression levels of IL-10 and TGF-β significantly increased (P<0.05, P<0.01). The expression of CD86 significantly decreased (P<0.01), and the expression of CD206 significantly increased (P<0.01). The protein and mRNA expressions of iNOS and CD86 significantly decreased (P<0.01), and those of Arg-1 significantly increased (P<0.01). The protein and mRNA expressions of CD206 significantly increased (P<0.05, P<0.01), and the mRNA and protein expressions of related pathway molecules TLR4 and NF-κB significantly decreased (P<0.01). ConclusionYCHT ameliorates cholestatic liver injury in rats by improving bile metabolism,reducing bile duct dilatation,and mitigating inflammation. These effects are achieved through the inhibition of M1 macrophage activation and the promotion of M2 macrophage polarization,likely via modulation of the TLR4/NF-κB signaling pathway.

Cholestatic liver injury refers to the bile production, secretion, and excretion disorder caused by various reasons. It induces liver injury, metabolic disorders, and dysfunction of the hepatobiliary system, which can further develop into liver fibrosis, cirrhosis, liver failure, and even death. At present, the preferred drug for clinical treatment is ursodeoxycholic acid, which, however, induces adverse reactions and is intolerant in some patients. Yinchenhao Tang is a representative prescription of traditional Chinese medicine for the treatment of jaundice due to Yang jaundice. It has the effects of clearing heat, eliminating dampness, and removing jaundice and has shown good therapeutic effect in long-term clinical application. Modern pharmacological studies have found that this prescription has anti-inflammatory, anti-oxidation, bile acid balance-regulating, hepatocyte apoptosis-inhibiting and other liver-protecting effects. This paper reviews the relevant clinical and animal experimental studies on Yinchenhao Tang in the treatment of cholestatic liver injury in recent years. Yinchenhao Tang can intervene in the progression of cholestatic liver injury by regulating bile acid metabolism and excretion, reducing inflammatory response, inhibiting oxidative stress, alleviating endoplasmic reticulum stress, inhibiting hepatocyte apoptosis, and protecting intestinal mucosal barrier. This paper systematically expounds the molecular mechanisms by which Yinchenhao Tang regulates cholestatic liver injury that are confirmed by current research, aiming to provide reference for the clinical application and in-depth study of Yinchenhao Tang.

OBJECTIVES:
To study the therapeutic mechanism of Tuihuang Mixture against cholestasis.
METHODS:
Forty-eight Wistar rats were randomized equally into blank group, model group, ursodeoxycholic acid group and Tuihuang Mixture group. Except for those in the blank group, all the rats were given α‑naphthylisothiocyanate (ANIT) to establish rat models of cholestasis, followed by treatments with indicated drugs or distilled water. Serum levels of ALT, AST, ALP, γ-GT, TBA and TBIL of the rats were determined, and hepatic expressions IL-1β, IL-18, FXR, NLRP3, ASC, Caspase-1 and GSDMD were detected using q-PCR, ELISA or Western blotting. Histopathological changes of the liver tissues were observed using HE staining.
RESULTS:
The rat models of cholestasis had significantly increased serum levels of ALT, AST, ALP, γ-GT, TBA and TBIL with increased mRNA and protein expressions of IL-1β and IL-18, decreased protein and mRNA expressions of FXR, and increased protein expressions of NLRP3 and Caspase-1 and mRNA expressions of NLRP3, ASC, Caspase-1 and GSDMD in the liver tissue, showing also irregular arrangement of liver cells, proliferation of bile duct epithelial cells and inflammatory cells infiltration. Treatment of the rat models with Tuihuang Mixture significantly decreased serum levels of ALT, AST, ALP, γ-GT, TBA and TBIL, lowered IL-1β and IL-18 and increased FXR protein and mRNA expressions, and reduced NLRP3, ASC, Caspase-1 and GSDMD proteins and NLRP3, ASC and Caspase-1 mRNA expressions in the liver tissue. Tuihuang Mixture also significantly alleviated hepatocyte injury, bile duct epithelial cell proliferation and inflammatory cell infiltration in the liver of the rat models.
CONCLUSIONS
Tuihuang Mixture can effectively improve cholestasis in rats possibly by inhibiting NLRP3 inflammatosome-mediated pyroptosis via regulating FXR.

ObjectiveTo investigate the impact of metabolic associated fatty liver disease (MAFLD) on metabolic markers in patients with HIV infection, and to assess the risk of new-onset MAFLD in previously untreated HIV patients. MethodsA total of 161 HIV patients who attended the outpatient service of Zhongnan Hospital of Wuhan University from April 2020 to December 2021 were enrolled, and they were treated with the lamivudine/efavirenz/tenofovir disoproxil fumarate (3TC/EFV/TDF) regimen and were followed up for more than 36 months. According to the presence or absence of MAFLD, they were divided into MAFLD group with 42 patients and non-MAFLD group with 119 patients, and metabolic markers were compared between the two groups before and after treatment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the paired t-test was used for comparison within each group before and after treatment; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Wilcoxon signed-rank test was used for comparison within each group before and after treatment; the chi-square test was used for comparison of categorical data between groups. Hepatic steatosis index (HIS) and Zhejiang University (ZJU) index were used to assess the risk of new-onset MAFLD after antiretroviral therapy. ResultsAfter 36 months of 3TC/EFV/TDF treatment, the MAFLD group had significant increases in body mass index (BMI) [24.8 (23.2 — 25.9) kg/m2 vs 25.3 (22.8 — 27.7) kg/m2, Z=-2.540, P=0.011], total cholesterol (TC) (4.0±0.6 mmol/L vs 4.3±0.6 mmol/L, t=-2.388, P=0.022), and high-density lipoprotein cholesterol (HDL-C) [0.9 (0.8 — 1.1) mmol/L vs 1.1 (0.9 — 1.2) mmol/L, Z=-2.858, P=0.004] and a significant reduction in serum uric acid (462.1±101.6 μmol/L vs 383.3±85.2 μmol/L, t=4.361, P<0.001). There was a significant difference in BMI between the MAFLD group and the non-MAFLD group after 3TC/EFV/TDF treatment [25.3 (22.8 — 27.7) kg/m2 vs 21.6 (19.9 — 23.4) kg/m2, Z=-5.462, P<0.001], while there were no significant differences between the two groups in serum uric acid, TC, triglyceride, HDL-C, low-density lipoprotein cholesterol, lipoprotein a, and CD4+ T cell count (all P >0.05). Furthermore, for the patients in the non-MAFLD group after treatment, there was a significant increase in the proportion of patients at a high risk of MAFLD based on HSI and ZJU indices (χ²=10.829 and 5.658, P=0.001 and 0.017). ConclusionAfter 36 months of 3TC/EFV/TDF treatment, there are increases in blood lipid levels in HIV patients with MAFLD, and there is an increase in the risk of new-onset MAFLD in HIV patients without MAFLD.

As a type of endogenous small non-coding RNA, microRNA (miRNA) can regulate gene expression and thereby intervene against the development and progression of cardiovascular diseases, neurodegenerative diseases, metabolic diseases, and autoimmune diseases. The pathogenesis of cholestasis is complex and is mainly associated with the metabolism and transport of bile acids, oxidative stress, inflammatory response, and intestinal flora. Currently, ursodeoxycholic acid is the preferred drug for the clinical treatment of cholestasis, but it may cause adverse reactions and exhibit poor efficacy in some patients. Studies have shown that miRNA can intervene in the disease process of cholestasis through multiple mechanisms such as regulating bile acid metabolism and transport, alleviating oxidative stress, inhibiting inflammatory response, improving cholangiocyte proliferation, and regulating intestinal flora. It can be used as a new biomarker and action target for cholestasis, with high research potential and value. Therefore, this article summarizes the role and mechanisms of miRNA in regulating cholestasis in recent years, in order to provide a reference for further research on the prevention and treatment of cholestasis by targeting miRNA.

Objective Depression,a most common psychiatric disease,is defined in Traditional Chinese Medicine(TCM)as Yu Syndrome,i.e.,depression disorder,or Baihe Disease,i.e.,lily bulb disease,a category of emotional disorders treated with lily-based TCM preparations.In TCM,depression is managed through syndrome differentiation and treatment,which is characterized by high efficacy and safety.However,there is no unified standard for the classification of depression syndromes,which leads to a disconnection between the analysis of patients'medication patterns and their actual syndromes and hinders the study of medication patterns specific to particular syndromes.Therefore,this study is focused on investigating the medication patterns of different sub-types of depression patients based on an objective classification system of depression.Methods We searched for and retrieved clinical literature on TCM formulas for depression from relevant databases,including China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP Database,Sinomed,Web of Science,and PubMed.Information on patient symptoms and medication was standardized.Then,the symptoms and the medication frequency of depression patients were statistically analyzed.We used the K-means clustering method combined with implicit structural analysis to objectively categorize depression patients into sub-types.In addition,the main symptoms and core TCM formulas of each sub-type of depression patients were identified.On the basis of objective classification system,we also statistically analyzed the characteristics of herbs used on depression patients,including the 4 basic properties,the 5 flavors,the attributes,the therapeutic efficacy,and the co-occurrence patterns,which may help reveal the medication patterns.Results A total of 3 537 publications and 4 434 prescriptions were included in the analysis.By using the K-means algorithm and latent structure analysis methods,patients with depression were categorized into 9 sub-types,with Cluster 6 accounting for the largest proportion.The most common symptoms among depression patients were insomnia and a depressed mood.Medication frequency analysis showed that Radix Bupleuri(Chai Hu),Radix Paeoniae Alba(Bai Shao),Poria(Fu Ling),Rhizoma Chuanxiong(Chuan Xiong),and Radix Curcumae(Yu Jin)were the most commonly used TCM herbs.For the depression sub-types of Clusters 1,2,and 6,blood-activating and stasis-dissolving herbs were used most often.The depression sub-types of Clusters 3,4,5,8,and 9 were mainly treated with qi-regulating herbs,while the depression sub-type of Cluster 7 was treated with qi-supplementing herbs.Depression patients were mostly treated with herbs that were cold or warm in nature and had sweet,bitter,and pungent flavors.Moreover,treatments for Cluster 1 and Cluster 6 mainly targeted the spleen meridian,while those for Cluster 2,Cluster 3,Cluster 4 and Cluster 5 mainly targeted the heart meridian.The treatments for the other sub-types mainly targeted the liver meridian.The core TCM formulas for the 9 depression sub-types included Zishui Qinggan Decoction,Danzhi Xiaoyao Powder,Huanglian Wendan Tang,Chaihu Guizhi Tang,Modified Xiaoyao Powder,Qinggan Jieyu Tang,Xiaoyao Powder,Xuefu Zhuyu Decoction,and Bazhen Decoction.The most commonly used Chinese herbal medicinal formulas were Gan Cao-Chai Hu,Bai Shao-Chai Hu,and Chen Pi-Chai Hu.Conclusion Based on machine learning,this study reveals the scientific aspects of TCM typing and syndrome-based treatment.It clarifies the rationale for targeting different symptoms in depression treatment and provides theoretical support for clinicians to make medication prescriptions.It also presents a new perspective for investigating TCM medication patterns.

OBJECTIVE To review the current research progress on pharmacoeconomics evaluation related to spinal muscular atrophy (SMA), in order to provide valuable insights for clinical treatment, screening and medical insurance payment decision- making. METHODS A computerized search was conducted across multiple databases including PubMed, Web of Science, Embase, Scopus, Cochrane Library, EBSCOhost, CNKI, VIP, CBM and Wanfang database as well as other important health technology assessment (HTA) websites, such as National Institute for Health and Care Research,International Society of Technology Assessment in Health Care, Agency for Healthcare Research and Quality, etc. The pharmacoeconomics evaluation studies related to SMA were collected from the inception to December 31st, 2023. The literature/reports were rigorously screened based on predefined inclusion and exclusion criteria by two researchers, and the essential information from the included literature/ reports was extracted using Excel 2019. The quality of the included literature/reports was evaluated by Consolidated Health Economic Evaluation Reporting Standards 2022. RESULTS Finally, 9 articles and 15 HTA reports were included, with overall good quality of literature, but poor quality of HTA reports. There were a total of 24 studies on the pharmacoeconomics evaluation of SMA, including treatment options such as nusinersen sodium, sovaprevir, risperidone, and best supportive therapy.The review results showed that nusinersen sodium was not cost-effective in the treatment of SMA; there was no consensus on the economic viability of treatment options such as risperidone and sovaprevir; newborn/prenatal screening combined withmedication therapy was cost-effective. CONCLUSIONS newborn/prenatal screening combined with SMA medication therapy demonstrates economic advantages. It is suggested to further investigate the cost-effectiveness of new SMA drugs and SMA screening in China, taking localization parameters and medical insurance prices into account, and gradually incorporate SMA screening into the scope of neonatal genetic disease detection, in order to alleviate the financial burden of patients’ families and healthcare systems.

This study was performed to investigate the features of HBV-specific CD8+T cell reactivity in patients with chronic hepatitis B(CHB),HBV-induced liver cirrhosis(LC)or hepatocellular carcinoma(HCC).A total of 124 CHB patients,36 LC patients,and 114 HCC patients were enrolled in this study.The reactive HBV-specific CD8+T cells in peripheral blood were enumerated using an innovative ELISPOT system.In addition,19 CHB patients and 20 HCC patients were longitudinally monitored with an interval of 3-5 months.Data showed that the numbers of reactive HBV-specific CD8+T cells in CHB group were not significantly different from that in LC group,but obviously lower than that in HCC group(P=0.009 9),especially HBsAg-,HBpol-and HBe/cAg-specific CD8+T cells.In CHB group,the patients with normal ALT level,AST level,or low HBV-DNA load showed significantly more reactive HBV-specific CD8+T cells than the patients with abnormal ALT level,abnormal AST level,or high HBV-DNA load.Furthermore,the duration of NUCs treatment had an impact on the HBV-specific CD8+T cell reactivity in CHB patients,while different NUCs at the same treatment duration did not bring different reactivity of HBV-specific T cells.In LC group,the HBeAg-positive patients presented much more reactive HBV-specific CD8+T cells than the HBeAg-negative patients did.In HCC group,the numbers of reactive HBV-specific CD8+T cells in the patients with normal AFP level or normal DCP level were significantly higher than that in the patients with abnormal AFP level or abnormal DCP level.Longitudinal monitoring results showed that HBV-specific CD8+T cell reactivity displayed a slow upward trend in the CHB patients undergoing NUCs treatment,and an obvious increasing in the HCC patients undergoing combined treatment of targeted drugs and immunotherapy.Taken together,the features of HBV-specific CD8+T cell reactivity are distinct among the CHB,LC and HCC patients,and are influenced by virological indicators,tumor markers and treatment regimens.Therefore,more attention should be paid to the changes of HBV-specific CD8+T cell reactivity during clinical treatment.
