ObjectiveTo investigate the effects of Yishen Juanbi pills (YSJB)-containing bone marrow fluid on the migration and differentiation phenotypes of CD4⁺T lymphocytes based on the stromal cell-derived factor-1/chemokine receptor 4 (SDF-1/CXCR4) signaling pathway. MethodsPrimary CD4⁺T lymphocytes were isolated from mice using magnetic bead separation and identified for purity by flow cytometry. A CD4⁺T lymphocyte culture system was then established to observe the effects of SDF-1 on CD4⁺T-cell migration and differentiation. On this basis, the experimental groups included the Sham group, the ovariectomy (OVX) group, the Sham+collagen-induced arthritis (CIA) group, the OVX+CIA group, the Sham+CIA+YSJB group (2.16 g·kg-1), the OVX+CIA+YSJB group (2.16 g·kg-1), and the OVX+CIA+methotrexate (MTX) group (1.5 mg·kg-1). Bone marrow fluid from each group was prepared according to previous methods and added to the CD4⁺ T-cell culture system at 5% (v/v). Transwell assays were used to examine CD4⁺T-cell migration in each group. Real-time PCR was used to measure the mRNA expression levels of interleukin (IL)-17, tumor necrosis factor-α (TNF-α), retinoic-acid-related orphan receptor γt (RORγt), IL-10, transforming growth factor-β (TGF-β), forkhead box P3 (FoxP3), CXCR4, phosphoinositide 3-kinase (PI3K), and protein kinase B (Akt). Western blot was used to detect the expression of helper T (Th)17/regulatory T (Treg) cell signature factors (RORγt, FoxP3), CXCR4, PI3K, phosphorylated (p)-PI3K, Akt, and p-Akt. In a separate set of experiments, cells were divided into the Sham group, OVX+CIA group, OVX+CIA+CXCR4 antagonist AMD3100 group, and OVX+CIA+YSJB+AMD3100 group to observe changes in the above indicators following AMD3100 intervention. ResultsCompared with the Sham group, the number of migrated cells in the lower chamber was significantly increased in the Sham+CIA and OVX+CIA groups (P<0.05, P<0.01). The mRNA expression of RORγt, IL-17, TNF-α, CXCR4, PI3K, and Akt was significantly upregulated, whereas FoxP3, IL-10, and TGF-β mRNA expression was significantly decreased (P<0.05, P<0.01). Protein expression of RORγt, CXCR4, p-PI3K/PI3K, and p-Akt/Akt was significantly increased, while FoxP3 protein expression was markedly decreased (P<0.05, P<0.01). Compared with the OVX+CIA group, the OVX+CIA+YSJB group and OVX+CIA+MTX group showed significantly reduced migration (P<0.05), mRNA expression of RORγt, IL-17, TNF-α, CXCR4, PI3K, and Akt was also significantly decreased, while FoxP3, IL-10, and TGF-β mRNA expression was significantly increased (P<0.05, P<0.01). RORγt protein expression was significantly downregulated, and FoxP3 protein expression markedly upregulated (P<0.05). In the OVX+CIA+YSJB group, CXCR4, p-PI3K/PI3K, and p-Akt/Akt protein expression was significantly decreased (P<0.05). Compared with the OVX+CIA group, RORγt, CXCR4, PI3K, and Akt mRNA expression in CD4⁺T cells was significantly decreased in the OVX+CIA+AMD3100 group and the OVX+CIA+YSJB+AMD3100 group, while FoxP3 mRNA and protein expression was significantly upregulated (P<0.05, P<0.01). RORγt, CXCR4, p-PI3K/PI3K, and p-Akt/Akt protein expression was also markedly decreased (P<0.05, P<0.01). Compared with the OVX+CIA+AMD3100 group, the OVX+CIA+YSJB+AMD3100 group showed significantly decreased RORγt and Akt mRNA expression (P<0.05) and significantly lower p-Akt/Akt protein expression (P<0.05). ConclusionYSJB-containing bone marrow fluid suppresses CD4⁺T-cell migration and regulates Th17/Treg balance by downregulating Th17-associated signature factors and upregulating Treg-associated signature factors through inhibition of the SDF-1/CXCR4 signaling pathway and PI3K/Akt signaling pathway. The SDF-1/CXCR4 signaling pathway is one of the targets through which YSJB inhibits CD4⁺T-cell differentiation.

ObjectiveTo explore the mechanism of Yinchenhao Tang regulating the tumor necrosis factor receptor superfamily member 6 (Fas)/cysteine protease-8 (Caspase-8)/cysteine protease-3 (Caspase-3) signaling pathway to inhibit hepatocyte apoptosis and improve cholestatic liver injury (CLI). MethodsAmong 48 Wistar rats,12 rats were randomly selected as the blank group,and the other rats were administered alpha-naphthalene isothiocyanate (ANIT) by gavage to induce a CLI model. The modeling rats were randomly divided into the model group, the ursodeoxycholic acid group(0.1 g·kg-1) and the Yinchenhao Tang group(9.23 g·kg-1),with 12 rats in each group. The rats in each group were given corresponding drugs by gavage for three consecutive days. The levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),gamma-glutamyl transpeptidase (γ-GT),total bilirubin (TBil) and total bile acid (TBA) in serum were detected. The levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in liver tissue were detected. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. The protein and mRNA expressions of Fas,Caspase-8,Caspase-3,B-cell lymphoma-2 (Bcl-2) associated X protein (Bax) and Bcl-2 in liver tissue were detected by Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with those in the blank group,the levels of ALT,AST,ALP,γ-GT,TBA and TBil in serum of the model group were significantly increased (P<0.01). The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly increased (P<0.01). The arrangement of hepatocytes was disordered,and inflammatory cell infiltration and bile duct epithelial cell proliferation were observed. The protein and mRNA expressions of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly increased(P<0.05,P<0.01),while the protein and mRNA expressions of Bcl-2 were significantly decreased (P<0.05,P<0.01). Compared with those in the model group,the levels of ALP,γ-GT,TBA and TBil in the serum of rats in the ursodeoxycholic acid group were significantly decreased. The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased(P<0.05,P<0.01). The protein and mRNA expressions of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly decreased (P<0.05,P<0.01),while the mRNA expression of Bcl-2 was significantly increased (P<0.05,). The levels of ALT,AST,γ-GT,TBA and TBil in the serum of rats in the Yinchenhao Tang group were significantly decreased (P<0.01). The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased (P<0.05,P<0.01). The protein expression of Fas and Bax and the mRNA expression of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly decreased (P<0.05,P<0.01),while the protein and mRNA expression of Bcl-2 were significantly increased (P<0.05,P<0.01). Hepatocyte injury,inflammatory cell infiltration and proliferation of bile duct epithelial cells were reduced. ConclusionYinchenhao Tang can ameliorate CLI,and its mechanism may be related to inhibiting hepatocyte apoptosis mediated by the Fas/Caspase-8/Caspase-3 signaling pathway.

ObjectiveTo study the mechanism of Yinchenhao Tang on the improvement of cholestatic liver injury (CLI) by inhibiting toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear transcription factor-κB (NF-κB) pathway via regulating farnesol X receptor (FXR). MethodsA total of 40 Wistar male rats were randomly selected, with 10 as a blank group,and the remaining rats were subjected to the CLI model induced by alpha-naphthalene isothiocyanate (ANIT). After modeling,they were randomly divided into the model group, the ursodeoxycholic acid (0.1 g·kg-1) group and the Yinchenhao Tang (9.23 g·kg-1) group,with 10 animals in each group. Each administration group was given the corresponding drug by intragastric administration for three consecutive days. Alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),γ-glutamyl transpeptidase (γ-GT),total bile acid (TBA),total bilirubin (TBil) and direct bilirubin (DBil) levels in serum were detected. Tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β),and interleukin-6 (IL-6) levels in liver tissue were detected. Real-time PCR was used to detect the mRNA expression of FXR,TLR4,MyD88,NF-κB,F4/80,TNF-α,IL-1β and IL-6 in liver tissue. Western blot was used to detect protein expression of FXR,TLR4,MyD88 and NF-κB in liver tissue. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. ResultsCompared with those in the blank group,ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the model group were significantly increased (P<0.01). The levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were significantly increased (P<0.01),and the mRNA and protein expressions of FXR in liver tissue were decreased (P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 were obviously increased (P<0.05,P<0.01). Hepatic histopathology showed inflammatory cell infiltration and proliferative changes of bile duct epithelial cells. Compared with those in the model group,ALT,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the ursodeoxycholic acid group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.05,P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 in liver tissue were obviously decreased (P<0.05,P<0.01). ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in the serum of rats in the Yinchenhao Tang group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.01). The mRNA and protein expressions of FXR in liver tissue were significantly increased,and the mRNA expressions of TLR4,MyD88,NF-κB,and F4/80, as well as the protein expressions of TLR4 and NF-κB were obviously decreased (P<0.05,P<0.01). The inflammatory cell infiltration of liver tissue and the proliferation of bile duct epithelial cells decreased. ConclusionYinchenhao Tang has an obvious protective effect on CLI,and its mechanism may be related to regulating FXR to inhibit TLR4/MyD88/NF-κB pathway-mediated inflammatory response.

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.

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.

Isosteviol is a tetracyclic diterpenoid compound obtained by hydrolysis of natural stevia glycoside under acidic conditions. It has many pharmacological activities, such as anti-tumor, hypoglycemic, anti-inflammatory and antibacterial. Due to its low water solubility, low activity and low bioavailability, isosteviol has poor performance. In order to overcome these shortcomings, scholars have obtained a large number of isosteviol derivatives with novel structures and excellent activity. In this paper, we review the recent progress in the research on the structure modification, biological activity, structure-activity relationship and microbial transformation of isosteviol, in order to provide a reference for the development of new drugs of isosteviol and its derivatives.

ObjectiveTo investigate the role and mechanism of action of paeoniflorin (PF) in protecting HepG2 cells induced by palmitic acid (PA). MethodsHepG2 cells were stimulated with PA at a concentration of 250 μmol/L to establish a NAFLD model. Compound C at a concentration of 10 μmol/L was used as an inhibitor, and PF at a concentration of 25 μmol/L was used for intervention. The experiment was divided into normal group (CON group) treated with complete culture medium, model group (MOD group) treated with PA, PF treatment group (MOD+PF group) treated with PA and PF, model+inhibitor group (MOD+COM group) treated with PA and Compound C, and model+inhibitor+PF group (MOD+COM+PF group) treated with PA, Compound C, and PF. Kits were used to measure lipid deposition indicators, liver function parameters, oxidative stress indicators, and inflammation indicators; oil red O staining was used to observe lipid deposition; Western Blot was used to measure the protein expression levels of AMPK, SIRT1, PGC-1α, mTOR, Beclin-1, LC3, and P62 in cells. The one-way analysis of variance was used for comparison of quantitative data between groups, while the Tukey’s test was used for comparison between two groups. ResultsCompared with the MOD group, PF improved the levels of TC and TG (P<0.05), reduced the levels of ALT, AST, CRP, TNF-α, IL-1β, and IL-6 (P<0.05), increased the activity of SOD and CAT and the level of GSH, and reduced the level of MDA in cells (all P<0.05). Oil red O staining showed that PF alleviated lipid deposition in cells. Western blot results showed that compared with the MOD group, PF increased the protein expression levels of p-AMPK, SIRT1, PGC-1α, LC3Ⅱ/LC3Ⅰ, and Beclin-1 and reduced the protein expression levels of p-mTOR and P62 (all P<0.05). ConclusionPF can inhibit PA-induced oxidative stress and inflammatory response in HepG2 cells, improve lipid deposition, and promote autophagy via the AMPK/SIRT1/PGC-1α/mTOR signaling pathway.
8.Connotation and Clinical Application of "The Nature of Cold and Heat Complex Syndrome is Cold": from the Perspective of Zang-Fu (脏腑) Wind-Damp Theory

Journal of Traditional Chinese Medicine 2025;66(8):795-799
According to zang-fu (脏腑) wind-damp theory, it is believed that wind, cold, and dampness are internal pathogenic factors that, when stagnated, transform into heat and invade the zang-fu organs, leading to chronic conditions. Heat is seen as a manifestation, while cold is considered the root cause. When external factors trigger these latent pathogens, the disease of the zang-fu organs exacerbates or relapses, often presenting with a complex syndrome of cold and heat. Based on this theory, the viewpoint of "for complex syndrome of cold and heat, cold is the root" is proposed. It suggests that for diseases with a complex cold-heat syndrome, external invasion of wind, cold, and dampness are the initiating factors. During the acute phase, treatment should focus on dispelling and eliminating the pathogens to promote the expulsion of the latent wind, cold, and dampness. During the remission phase, the focus shifts to reinforcing the healthy qi and tonifying the root, allowing the cold and dampness to be cleared. Internal dampness originates from the spleen; therefore, regulating the spleen and stomach, and dispersing cold and removing dampness is the key to treating wind-damp disorders of zang-fu organs. Cold and dampness are both yin pathogens, which damage yang qi, and repeated invasions of wind, cold, and dampness obstruct the qi flow of the zang-fu organs, progressively weakening yang qi. Hence, it is necessary to protect yang qi, and thereafter dispelling cold and dampness by warming yang. The theory that "for complex syndrome of cold and heat, cold is the root" provides guidance for the clinical application and the treatment of complex and difficult diseases in traditional Chinese medicine.

ObjectiveTo understand the infection characteristics of multidrug-resistant organisms (MDROs) in hospitalized patients in a tertiary sentinel hospital in Shanghai, so as to provide an evidence for the development of targeted prevention and control measures. MethodsData of MDROs strains and corresponding medical records of some hospitalized patients in a hospital in Shanghai from 2021 to 2023 were collected, together with an analysis of the basic information, clinical treatment, underlying diseases and sources of sample collection. ResultsA total of 134 strains of MDROs isolated from hospitalized patients in this hospital were collected from 2021 to 2023 , including 63 strains of methicillin-resistant Staphylococcus aureus (MRSA), 57 strains of carbapenem-resistant Acinetobacter baumannii (CRAB), and 14 strains of carbapenem-resistant Klebsiella pneumoniae (CRKP). Of the 134 strains, 30 strains were found in 2021, 47 strains in 2022 and 57 strains in 2023. The male-to-female ratio of patients was 2.05∶1, with the highest percentage (70.90%) in the age group of 60‒<90 years. The primary diagnosis was mainly respiratory disease, with lung and respiratory tract as the cheif infection sites. There was no statistically significant difference in the distribution of strains between different genders and infection sites (P>0.05). However, the differences in the distribution of strains between different ages and primary diagnosis were statistically significant (P<0.05). Patients who were admitted to the intensive care unit (ICU), had urinary tract intubation, were not artery or vein intubated, were not on a ventilator, were not using immunosuppresants or hormones, and were not applying radiotherapy or chemotherapy were in the majority. There was no statistically significant difference in the distribution of strains for whether received radiotherapy or chemotherapy or not (P>0.05), while the differences in the distribution of strains with ICU admission history, urinary tract intubation, artery or vein intubation, ventilator use, and immunosuppresants or hormones use or not were statistically significant (all P<0.05). The type of specimen was mainly sputum, the hospitalized ward was mainly comprehensive ICU, the sampling time was mainly in the first quarter throughout the year, the number of underlying diseases was mainly between 1 to 2 kinds, the application of antibiotics ≥4 kinds, and those who didn’t receive any surgery recently accounted for the most. There were statistically significant differences in the distribution of strains between different specimen types, wards occupied and history of ICU stay (P<0.05), but no statistically significant difference in the distribution of strains between different sampling times, number of underlying diseases and types of antibiotics applied (P>0.05). ConclusionThe situation of prevention and control on MDROs in this hospital is still serious. Focus should be placed on high-risk factors’ and infection monitoring and preventive measures should be strengthened to reduce the incidence rate of MDROs infection.

ObjectiveTo develop a scale for evaluating the syndrome of internal retention of dampness and turbidity in nonalcoholic fatty liver disease (NAFLD) that combines disease and syndrome and has the characteristics of traditional Chinese medicine (TCM). MethodsAn item pool was established for evaluating the syndrome of internal retention of dampness and turbidity in nonalcoholic fatty liver disease (NAFLD) with reference to the guideline for developing international scales. A clinical survey was conducted among the outpatients and inpatients who were diagnosed with NAFLD and had the syndrome of internal retention of dampness and turbidity in Department of Hepatology and Spleen-Stomach, The First Affiliated Hospital of Henan University of Chinese Medicine, from June to August, 2023, and the items were screened based on the classical test theory and the item response theory. An expert questionnaire was developed, and expert discussions were conducted using the Delphi method to identify the items for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD. Finally, the scale was given scientific scores. ResultsA preliminary item pool was established, with 16 primary items and 22 secondary items, and it was divided into the two dimensions of disease and syndrome type. Clinical pre-survey suggested to retain 9 primary items and 14 secondary items, while the Delphi expert questionnaire recommended to retain 11 primary items and 15 secondary items, and tongue manifestation and pulse manifestation were no longer used for assessing the severity of syndrome. After hierarchical analysis and scientific assignment of scores, the scale for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD had a total score of 123 points and 9 important items, i.e., discomfort in the hypochondrium, abdominal fullness and distension, obesity, heaviness of the head and body, loose stool, anorexia, coughing up phlegm, nausea with a tendency to vomit, and lethargy. ConclusionA preliminary scale is established for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD, which fills the gap in this research field and provides a basis for further clinical application.
