Objective To explore the prevalence of Helicobacter pylori (Hp) infection and its association with dietary and lifestyle habits among the adult physical examination population in Xuzhou area. Methods Retrospectively selected the physical examination population who underwent HP testing at our hospital's physical examination center from May 2021 to December 2023 as the research object. The prevalence of Hp infection in the population was analyzed based on the physical examination results. A questionnaire survey was used to collect information on the eating and living habits of all study subjects. Logistic regression was used to analyze the relationship between eating and living habits and Hp infection. Results A total of 1 354 physical examination people were included in the study, and the Hp infection rate was 37.30% (505/1354). The difference in Hp infection rates among people of different age groups is statistically significant (P<0.05), with the middle-aged population (41-59 years old) having the highest Hp positive infection rate (45.38%).High salt (41.11%), hot diet (40.56%), history of smoking (45.23%) and drinking (43.80%), less consumption of fruits and vegetables (43.73%), irregular exercise (41.29%), irregular diet People who frequently eat out (43.56%) and eat out frequently (42.57%) have a higher Hp infection rate (P<0.05).After adjusting for demographic factors such as gender, age, place of residence and education level, multivariate Logistic regression results showed that high-salt diet (OR=3.975, 95%CI: 2.670-5.917) and hot diet (OR=3.357, 95%CI: 2.291-4.919), smoking (OR=1.458, 95%CI: 1.082-1.964), drinking alcohol (OR=1.654, 95%CI: 1.279-2.138), eating fruits and vegetables (OR=1.759, 95%CI: 1.345-2.301), regular exercise (OR=1.822, 95%CI: 1.371-2.421), regular diet (OR=1.893, 95%CI: 1.391-2.575), eating out (OR=1.690, 95%CI: 1.277-2.237) were associated with the risk of Hp infection (P<0.05). Conclusion The positive infection rate of Hp among the physical examination population in Xuzhou is slightly lower than the average epidemic level in China. Cultivating healthy eating and living habits can effectively reduce the risk of Hp infection.

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.

ObjectiveTo investigate the role of mature-tRNA-Asp-GTC and pre-tRNA-Arg-TCT in the ferroptosis phenotype of ovarian cancer (OC) cells and the regulatory mechanism of gypenoside L (Gyp-L) on mature-tRNA-Asp-GTC and pre-tRNA-Arg-TCT in OC cells. MethodsThe proliferation of human ovarian adenocarcinoma OVCAR3 cells was detected by cell counting kit-8 (CCK-8) assay, and the half-maximal inhibitory concentration (IC50) values of cisplatin (DDP), Gyp-L, and DDP in the presence of Gyp-L were calculated to determine the intervention concentration for subsequent experiments. Cell cloning assay and scratch assay reflected the proliferation and migration ability of OVCAR3 cells. PANDORA-seq small RNA sequencing was used to detect the differentially expressed transfer RNA-derived small RNAs (tsRNAs) in the cells after Gyp-L intervention, and the corresponding target genes of the tsRNAs were found by the RNAhybrid software. Malondialdehyde (MDA), glutathione (GSH), and lipid peroxide (LPO) levels were measured by colorimetry or enzyme linked immunosorbent assay (ELISA) method, Fe2+ content by FerroOrange fluorescent probe, and reactive oxygen species (ROS) content by DCFH-DA fluorescent probe to reflect the occurrence of ferroptosis in OVCAR3 cells. OVCAR3 cells were divided into a control group, a 50 µmol·L-1 Gyp-L group, and a 100 µmol·L-1 Gyp-L group. Quantitative real-time polymerase chain reaction (PCR) was performed to detect the expression of mature-tRNA-Asp-GTC, mature-tRNA-Leu-CAA, mature-mt_tRNA-Tyr-GTA_5_end, mature-tRNA-Val-CAC, mature-mt_tRNA-Glu-TTC, pre-tRNA-Arg-TCT, mature-tRNA-Asn-GTT, hydroxymethylbilane synthase (HMBS), Wnt, β-catenin, glutathione peroxidase 4 (GPX4), Kelch-like ECH-associated protein 1 (KEAP1), nuclear factor erythroid 2-related factor 2 (Nrf2), activating transcription factor 3 (ATF3), cystine/glutamate antiporter xCT, lysophosphatidylcholine acyltransferase 3 (LPCAT3), and arachidonate 15-lipoxygenase (ALOX15). Western blot was performed to detect the expression of HMBS, Wnt, β-catenin, GPX4, KEAP1, Nrf2, ATF3, xCT, LPCAT3, and ALOX15 proteins. ResultsThe 50 µmol·L-1 Gyp-L, 100 µmol·L-1 Gyp-L, DDP, 50 µmol·L-1 Gyp-L+DDP, and 100 µmol·L-1 Gyp-L+DDP groups showed significantly inhibited proliferation and migration of OVCAR3 cells (P<0.05) and exacerbated cell ferroptosis as reflected by the increase in the content of ROS, MDA, LPO, and Fe2+, as well as a decrease in the content of GSH (P<0.05). Compared with the control group, Gyp-L effectively interfered with the expression of 25 tsRNAs in OVCAR3 cells (P<0.05, |log2Fc|>1). Pre-tRNA-Arg-TCT/HMBS/Wnt/β-catenin/GPX4, pre-tRNA-Arg-TCT/KEAP1/NRF2/xCT, mature-tRNA-Asp-GTC/ATF3/KEAP1/NRF2/xCT, and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 axial expression was significantly aberrant after Gyp-L intervention (P<0.05). ConclusionThe pre-tRNA-Arg-TCT/HMBS/Wnt/β-catenin/GPX4, pre-tRNA-Arg-TCT/KEAP1/Nrf2/xCT, mature-tRNA-Asp-GTC/ATF3/KEAP1/Nrf2/xCT, and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 signaling pathways are involved in OC development. Gyp-L inhibits OC development by activating OVCAR3 cell ferroptosis onset mainly through the mature-tRNA-Asp-GTC/ATF3/KEAP1/Nrf2/xCT and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 signaling axes.
