Objective This study aimed to analyze the characteristics and clinical significance of peripheral lymphocytic subsets and cytokine levels, including interleukin 1β(IL-1β), IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12P70, IL-17A, tumor necrosis factor α(TNF-α), interferon γ(IFN-γ) and IFN-α, in patients with primary biliary cholangitis (PBC), to provide some novel insights into the pathogenesis of PBC. Methods We retrospectively collected clinical features and laboratory data from hospitalized patients who were primarily diagnosed with PBC and from healthy physical examinees at the Third People's Hospital of Changzhou between January 1, 2023, and June 30, 2024. Results A total of 152 PBC patients and 96 healthy controls who met the inclusion and exclusion criteria were enrolled. Significant differences were observed in baseline characteristics and laboratory data between the two groups. After the propensity score matching (PSM) analysis, 61 PBC patients and 61 healthy controls were successfully matched, ensuring that the general characteristics (age and gender) of the two groups were balanced and comparable. Compared to the control group, the proportion of peripheral lymphocytes was significantly higher in the PBC group (31.9% vs. 17.8%), primarily due to an increase in CD4+ T cells (46.77% vs. 41.19%), while CD8+T cells were significantly decreased (19.73% vs. 22.07%). Notably, the proportions of CD4+ programmed cell death 1 (PD-1)+ T and CD8+PD-1+ T cells were elevated, with CD8+PD-1+ T cells showing a significant positive correlation with the severity of liver inflammation (r=0.41). Furthermore, the mitochondrial mass (MM) of CD4+ T cells was significantly increased in PBC patients, whereas no significant changes were observed in the MM of CD8+ T cells or the mitochondrial membrane potential (MMP) of CD3+ T cells. Additionally, the plasma levels of cytokines, such as IL-4, IL-8, IL-10 and IFN-α, were abnormally elevated. The plasma levels of IL-5 and IL-1β were negatively correlated with the stage of liver fibrosis in patients with PBC (r=-0.52). Conclusion The overactivation and proliferation of CD4+ T cells, along with the suppression of CD8+ T cell function and increased PD-1 expression leads to T cell exhaustion, indicating significant immunological alterations in PBC patients. These changes are closely associated with the disease progression. Additionally, cytokines are likely involved in the immune regulation process of PBC and may influence the pathogenic mechanisms of the disease. Regular monitoring of lymphocyte subsets and cytokine levels can help assess the immune status and disease activity in patients with PBC, thereby guiding the individualized treatment strategies.

Fetuin-B (FETUB) is a glycoprotein mainly synthesized and secreted by the liver. It is involved in many physiological and pathological processes including glucose metabolism, inflammatory response, nonalcoholic fatty liver disease, myocardial infarction, tumor and so on. In recent years, FETUB has also been confirmed to play roles in the female reproductive system. FETUB may affect follicular development and play an important role in in vivo and in vitro fertilization. In addition, serum FETUB level is elevated significantly during pregnancy and labor. FETUB expression is changed in a variety of reproductive diseases (polycystic ovary syndrome, gestational diabetes mellitus, intrahepatic cholestasis of pregnancy). In this review, we summarize FETUB related studies in female reproduction, and focus on the roles of FETUB in female reproductive physiology and pathology, in order to provide information for the pathogenesis of reproductive disorders.

3.Excerpt from the 2022 American Association for the Study of Liver Diseases clinical practice guideline: management of primary sclerosing cholangitis and cholangiocarcinoma.
Chinese Journal of Hepatology 2023;31(1):35-41
What are the new contents of the guideline since 2010?A.Patients with primary and non-primary sclerosing cholangitis (PSC) are included in these guidelines for the diagnosis and management of cholangiocarcinoma.B.Define "related stricture" as any biliary or hepatic duct stricture accompanied by the signs or symptoms of obstructive cholestasis and/or bacterial cholangitis.C.Patients who have had an inconclusive report from MRI and cholangiopancreatography should be reexamined by high-quality MRI/cholangiopancreatography for diagnostic purposes. Endoscopic retrograde cholangiopancreatography should be avoided for the diagnosis of PSC.D. Patients with PSC and unknown inflammatory bowel disease (IBD) should undergo diagnostic colonoscopic histological sampling, with follow-up examination every five years until IBD is detected.E. PSC patients with IBD should begin colon cancer monitoring at 15 years of age.F. Individual incidence rates should be interpreted with caution when using the new clinical risk tool for PSC for risk stratification.G. All patients with PSC should be considered for clinical trials; however, if ursodeoxycholic acid (13-23 mg/kg/day) is well tolerated and after 12 months of treatment, alkaline phosphatase (γ- Glutamyltransferase in children) and/or symptoms are significantly improved, it can be considered to continue to be used.H. Endoscopic retrograde cholangiopancreatography with cholangiocytology brushing and fluorescence in situ hybridization analysis should be performed on all patients suspected of having hilar or distal cholangiocarcinoma.I.Patients with PSC and recurrent cholangitis are now included in the new unified network organ sharing policy for the end-stage liver disease model standard.J. Liver transplantation is recommended after neoadjuvant therapy for patients with unresectable hilar cholangiocarcinoma with diameter < 3 cm or combined with PSC and no intrahepatic (extrahepatic) metastases.

This study aims to investigate the effect of Chaihu Shugan Powder(CHSG) on liver injury in rats with intrahepatic cholestasis by regulating farnesoid X receptor(FXR)/nuclear factor erythroid-2-related factor(Nrf2)/antioxidant response element(ARE) pathway. Eighty-four SD rats were classified into normal group, model group, CHSG-L group(0.5 g·kg~(-1)), CHSG-H group(2.5 g·kg~(-1)), ursodeoxycholic acid group(UDCA group, 100 mg·kg~(-1)), CHSG-H+sh-NC group(2.5 g·kg~(-1) CHSG+subcutaneous injection of sh-NC lentivirus), CHSG-H+sh-FXR group(2.5 g·kg~(-1) CHSG+subcutaneous injection of sh-FXR lentivirus), with 12 rats in each group. Rats were treated with corresponding drugs except for the normal group and the model group, once a day, for 7 days. On 5 th day, rats, except the normal group, were given α-naphthalene isothiocyanate(ANIT) at a dose of 100 mg·kg~(-1), once a day for 3 days to induce intrahepatic cholestasis, and the normal group was given the same amount of normal saline. Rats were anesthetized 1 h after the last administration and the 2 h bile flow was measured. Aeroset chemistry analyzer was employed to detect the levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBIL), and total bile acid(TBA) in rat serum. Based on hematoxylin and eosin(HE) staining, the pathological changes of rat liver tissue were observed. Glutathione peroxidase(GSH-Px), superoxide dismutase(SOD), and malondialdehyde(MDA) in rat liver tissue homogenate were monitored with corresponding kits. Western blot was used to detect the expression of FXR, Nrf2, and heme oxygenase-1(HO-1) proteins in rat liver tissue. Compared with the normal group, the model group showed many spots or concentrated necrotic areas in the liver tissue, infiltration of a large number of inflammatory cells, swelling liver cells with nuclear shrinkage. The 2 h bile flow, levels of GSH-Px and SOD, and relative expression of FXR, Nrf2, and HO-1 proteins were significantly lower, and the levels of ALT, AST, TBIL, TBA and MDA were significantly higher in the model group than in the normal group. Compared with the model group, CHSG-L group, CHSG-H group, and UDCA group demonstrated significant alleviation of pathological damage of the liver tissue, significantly high 2 h bile flow, levels of GSH-Px and SOD, and expression of FXR, Nrf2 and HO-1 proteins, and significantly low levels of ALT, AST, TBIL, TBA and MDA. Compared with the CHSG-H group, the CHSG-H+sh-FXR group had worse liver pathological damage, significantly low levels of 2 h bile flow, levels of GSH-Px and SOD, and expression of FXR, Nrf2, and HO-1 proteins, and significantly high levels of ALT, AST, TBIL, TBA, and MDA. CHSG may protect against liver injury in rats with intrahepatic cholestasis by activating the FXR/Nrf2/ARE pathway.

OBJECTIVES:
To systematically evaluate the risk factors for necrotizing enterocolitis (NEC) in preterm infants.
METHODS:
PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Data were searched for case-control studies and cohort studies on the risk factors for NEC in preterm infants published up to December 2021. RevMan 5.3 software was used to perform the Meta analysis.
RESULTS:
A total of 38 studies were included (28 case-control studies and 10 cohort studies). The Meta analysis showed that maternal gestational diabetes (OR=2.96, P<0.001), intrahepatic cholestasis during pregnancy (OR=2.53, P<0.001), preeclampsia (OR=1.73, P=0.020), history of neonatal asphyxia (OR=2.13, P<0.001), low gestational age (OR=1.23, P=0.010), sepsis (OR=5.32, P<0.001), patent ductus arteriosus (OR=1.57, P=0.001), congenital heart disease (OR=3.78, P<0.001), mechanical ventilation (OR=2.23, P=0.020), history of antibiotic use (OR=1.07, P<0.001), use of vasopressors (OR=2.34, P=0.040), and fasting (OR=1.08, P<0.001) were risk factors for NEC in preterm infants, while cesarean section (OR=0.73, P=0.004), use of pulmonary surfactant (OR=0.43, P=0.008), and breastfeeding (OR=0.24, P=0.020) were protective factors against NEC.
CONCLUSIONS
Maternal gestational diabetes, intrahepatic cholestasis during pregnancy, preeclampsia, low gestational age, fasting, sepsis, patent ductus arteriosus, congenital heart disease, and histories of asphyxia, mechanical ventilation, antibiotic use, and use of vasopressors may increase the risk of NEC in preterm infants, while cesarean section, use of pulmonary surfactant, and breastfeeding may decrease the risk of NEC in preterm infants.

Objective: To analyze the clinical characteristics and prognostic value of liver function in a large samples of patients with anti-glycoprotein 210 (gp210 antibody) positive primary biliary cholangitis (PBC). Methods: A retrospective study was performed on 931 PBC cases in Beijing You'an Hospital affiliated to Capital Medical University from 2010 to 2019. According to the detection of gp210 antibody, 318 cases were divided into gp210 antibody positive group (positive group) and 613 cases were divided into gp210 antibody negative group (negative group). The differences in demographic, medical history, clinical indicators, B-ultrasound and pathological indicators as well as the histopathological basis were compared between the two groups. SPSS 16.0 software was used for statistical analysis. Measurement data were analyzed by t-test or rank sum test, and enumeration data by χ2 test. Multivariate analysis was used for logistic test, and and survival analysis was used for prognosis. Results: The positive and the negative groups were compared. The ratio of male to female was significantly higher in positive than negative group (1:5.35 vs. 1:9.73, P<0.05), and the difference was statistically significant. The proportion of hormone use in history of past diagnosed and treated was higher in positive than negative group (12.9% vs. 3.47%, P<0.05), and the difference was statistically significant. The detection of biochemical indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT) were higher in positive than the negative group (51.1 U/L vs. 41.1 U/L, 62.6 U/L vs. 49.6 U/L, 24.1 μmol/L vs. 17.9 μmol/L, 228.3 U/L vs. 169.6 U/L, 203.9 U/L vs. 147.6 U/L), (P<0.05), and the differences were statistically significant. Antinuclear antibody (ANA)-positive rate, high titer ratio and immunoglobulin G (IgG) levels were higher in positive than negative group (95.2% vs. 81.6%, 69.7% vs. 48.8%, 17.2 g/L vs. 16.2 g/L), (P<0.05), and the differences were statistically significant. The incidence of liver failure was higher in positive than negative group (P<0.05). CK7 and inflammation score were higher in positive group than negative group in liver histopathological observations (0.83±0.53 vs. 0.28±0.47; 1.06±0.39 vs. 0.54±0.65), (P<0.05), and the differences were statistically significant. Conclusion: The illness condition of patients with gp210 antibody positive PBC is more severe than patients with gp210 antibody negative PBC, and the incidence of liver failure is significantly increased. Cholangiocytes may be the histopathological basis of the clinical characteristics of gp210 antibody positive PBC patients.

OBJECTIVE:
To explore the characteristics of SLC25A13 gene variants in 16 infants with neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD).
METHODS:
The infants were subjected to high-throughput DNA sequencing for coding exons and flanking regions of the target genes. Suspected variants were verified by Sanger sequencing and bioinformatic analysis.
RESULTS:
Among the 16 NICCD cases, 15 were found to harbor pathogenic variants. Among these, IVS14-9A>G, c.1640G>A, c.762T>A, c.736delG, c.1098Tdel and c.851G>A were previously unreported.
CONCLUSION
Six novel SLC25A13 variants were found by high-throughput sequencing, which has enriched the spectrum of SLC25A13 gene variants and provided a basis for genetic counseling and prenatal diagnosis.
