Hepatic fibrosis (HF) is a pathological process of abnormal repair of liver tissue structure caused by chronic liver injury, and its pathogenesis has not been fully clarified. Related studies have shown that programmed cell death may be associated with the onset of HF, and traditional Chinese medicine (TCM) has a significant effect in regulating programmed cell death to intervene against HF. This article reviews the main mechanism of the influence of programmed cell death on HF and discusses the possible mechanism of TCM regulation of programmed cell death in improving HF, which provides new ideas for TCM prevention and treatment of HF.

ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction (RD) retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy (MHE). MethodsA total of 60 male Sprague-Dawley rats were divided into blank group (CON group with 6 rats) and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks, 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group (MOD group), lactulose group (LT group), low-dose RD group (RD1 group), middle-dose RD group (RD2 group), and high-dose RD group (RD3 group), with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day; the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day; the rats in the RD1, RD2, and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5, 5.0, and 7.5 g/kg, respectively, once a day. After 10 days of treatment, the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects: behavioral status; the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) and the level of blood ammonia; pathological changes of liver tissue and brain tissue; the mRNA and protein expression levels of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) in brain tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the MOD group, the RD1, RD2, and RD3 groups had a significantly shorter escape latency (all P<0.01), significant reductions in the levels of ALT, AST, IL-1β, IL-6, TNF-α, and blood ammonia (all P<0.05), significant alleviation of the degeneration, necrosis, and inflammation of hepatocytes and brain cells, and significant reductions in the mRNA and protein expression levels of PI3K, AKT, and mTOR in brain tissue (all P<0.05), and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats, possibly by regulating the PI3K/AKT/mTOR signaling pathway.

Hepatic encephalopathy is a clinical syndrome of central nervous system dysfunction caused by liver insufficiency.It severely affects the quality of life of patients and may lead to death.Accurate prediction of the risk of developing hepatic encephalopathy is crucial for early intervention and treatment.In order to identify the risk of hepatic encephalopathy in patients in advance,many studies have been devoted to efforts to develop tools and methods to identify the risk of hepatic encephalopathy as early as possible,so as to develop preventive and early management strategies.Most conventional hepatic encephalopathy risk prediction models currently assess the prob-ability of a patient developing hepatic encephalopathy by analysing factors such as clinical data and biochemical indicators,however,their accuracy,sensitivity and positive predictive value are not high.The application of artificial intelligence to clinical predictive modelling is a very hot and promising area,which can use large amounts of data and complex algorithms to improve the accuracy and efficiency of diagnosis and prognosis.To date,there have been few studies using AI techniques to predict hepatic encephalopathy.Therefore,this paper reviews the research progress of hepatic encephalopathy risk prediction models,and also discusses the prospect of AI application in hepatic encephalopathy risk prediction models.It also points out the challenges and future research directions of AI in HE risk prediction model research in order to promote the development and clinical application of hepatic encephalopathy risk prediction models.

Objective:
Emerging evidence suggests that air pollution exposure may increase the risk of Parkinson’s disease (PD). We aimed to investigate the association between exposure to fine particulate matter (PM2.5) and the risk of incident PD nationwide.
Methods:
We utilized data from the Taiwan National Health Insurance Research Database, which is spatiotemporally linked with air quality data from the Taiwan Environmental Protection Administration website. The study population consisted of participants who were followed from the index date (January 1, 2005) until the occurrence of PD or the end of the study period (December 31, 2017). Participants who were diagnosed with PD before the index date were excluded. To evaluate the association between exposure to PM2.5 and incident PD risk, we employed Cox regression to estimate the hazard ratio and 95% confidence interval (CI).
Results:
A total of 454,583 participants were included, with a mean (standard deviation) age of 63.1 (9.9) years and a male proportion of 50%. Over a mean follow-up period of 11.1 (3.6) years, 4% of the participants (n = 18,862) developed PD. We observed a significant positive association between PM2.5 exposure and the risk of PD, with a hazard ratio of 1.22 (95% CI, 1.20–1.23) per interquartile range increase in exposure (10.17 μg/m3) when adjusting for both SO2 and NO2.
Conclusion
We provide further evidence of an association between PM2.5 exposure and the risk of PD. These findings underscore the urgent need for public health policies aimed at reducing ambient air pollution and its potential impact on PD.

ObjectiveTo investigate the therapeutic effect of rhubarb decoction (RD) retention enema on a rat model of minimal hepatic encephalopathy (MHE) and its mechanism of action based on bile acid (BA) metabolomics. MethodsA total of 55 male Sprague-Dawley rats were randomly divided into blank group (NC group with 10 rats), hepatic encephalopathy group (HE group with 15 rats), MHE group with 15 rats, and MHE+rhubarb decoction treatment group (MHEY group with 15 rats). Intraperitoneal injection of carbon tetrachloride (CCl4) and thioacetamide (TAA) was performed to establish a rat model of MHE or HE, and the rats were sacrificed after 2 weeks of administration. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin (TBil), and total bile acid (TBA) and the concentration of blood ammonia were measured; the colonic contents were collected to measure pH value; liver and brain tissue samples were collected, and HE staining was used to observe the histopathological changes of the liver; the bile was collected, and liquid chromatography-mass spectrometry was used to perform BA-targeted metabolomics analysis. Continuous data were expressed as mean±standard deviation; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the NC group, the HE group and the MHE group had a significant increase in searching platform latency (after modelling and after administration) and a significant reduction in the number of platform crossings (all P<0.05); compared with the MHE group, the MHEY group had a significant reduction in searching platform latency (after administration) and a significant increase in the number of platform crossings, and the HE group had a significant increase in searching platform latency and a significant reduction in the number of platform crossings (all P<0.05). Compared with the NC group, the HE group and the MHE group had significant increases in AST, ALT, ALP, TBil, TBA, blood ammonia, and colon pH value (all P<0.05); compared with the MHE group, the MHEY group had significant reductions in AST, ALT, ALP, TBil, TBA, blood ammonia, and colon pH value (all P<0.05), and the HE group had significant increases in AST, ALT, ALP, TBil, TBA, blood ammonia, and colon pH value (all P<0.05). The MHE group had significantly lower TBA, primary BA, and secondary BA than the NC group (all P<0.05); compared with the MHE group, the HE group had significantly lower TBA and primary BA (all P<0.05), and the MHEY group had significantly higher TBA and primary BA (all P<0.05). Compared with the NC group, the MHE group had significant reductions in GCDCA, GUDCA, GHDCA, TCDCA, TUDCA, GLCA, and TLCA (all P<0.05) and significant increases in γ-MCA, THCA, 7-KDCA, AlloLCA, and α-MCA (all P<0.05), and compared with the MHE group, the MHEY group had significant increases in THDCA, TMCA, TCDCA, TUDCA, and TLCA (all P<0.05). ConclusionRD retention enema can improve liver injury and cognitive function in a rat model of MHE induced by CCl4 and TAA by regulating the enterohepatic circulation of BA, possibly by increasing the synthesis of taurine-binding BA.

Objective: To investigate the familial heritability of endometriosis and to compare the clinical characteristics of patients with or without a family history of endometriosis. Methods: From January 2020 to June 2022, 850 patients with endometriosis confirmed by laparotomy or laparoscopy in Peking University Third Hospital were included in this study. Clinical data were collected, family history was followed up, and the differences of clinical indicators between patients with and without family history of endometriosis were compared. Results: A total of 850 patients were enrolled, with an average age of (33.8±7.0) years old, 315 (37.1%, 315/850) patients in stage Ⅲ and 496 (58.4%, 496/850) patients in stage Ⅳ. There were 100 patients with family history of endometriosis, accounting for 11.8% (100/850). Most of the 113 relatives involved were mothers, daughters and sisters (76.1%, 86/113), 81.5% (22/27) of the second and third degree relatives were maternal relatives. The median ages of patients with and without family history of endometriosis were 30 and 33 years old respectively at the time of diagnosis. The unmarried rate of patients with family history was higher [42.0% (42/100) vs 26.3% (197/750)]. The percentage of dysmenorrhea patients with family history was higher [89.0% (89/100) vs 55.5% (416/750)]. The medians of dysmenorrhea score in patients with and without family history were 6 and 2, and the median durations of dysmenorrhea were 10 and 1 years. There were significant differences in age, marital status, percentage of dysmenorrhea, dysmenorrhea score and duration (all P<0.001). The median levels of serum cancer antigen (CA) 125 in patients with family history and patients without family history at the time of diagnosis were 57.5 and 46.9 kU/L respectively, with a statistically significant difference (P<0.05). However, there were no significant differences between the two groups in nationality, bady mass index, menarche age, menstrual cycle, menstrual period, menstrual volume, serum CA19-9 level, cyst location and size, stage, history of adverse pregnancy and childbirth, infertility, adenomyosis and deep infiltrating endometriosis (all P>0.05). By comparing the specific conditions of dysmenorrhea patients with and without family history of endometriosis, there were no significant differences between the two groups in terms of the age of onset of dysmenorrhea, duration of dysmenorrhea, primary and secondary dysmenorrhea, and progressive aggravation of dysmenorrhea (all P>0.05). The difference in the degree of dysmenorrhea in dysmenorrhea patients with family history of endometriosis was significant (P<0.001). Conclusions: The incidence of endometriosis has a familial tendency, and most of the involved relatives are the first degree relatives. Compared with patients without family history of endometriosis, endometriosis patients with family history are diagnosed at an earlier age, with higher percentage of dysmenorrhea, had more severe dysmenorrhea and higher serum CA125 level.

This study aims to study the effective substance and mechanism of Ziziphi Spinosae Semen extract in the treatment of insomnia based on serum metabolomics and network pharmacology. The rat insomnia model induced by p-chlorophenylalanine(PCPA) was established. After oral administration of Ziziphi Spinosae Semen extract, the general morphological observation, pentobarbital sodium-induced sleep test, and histopathological evaluation were carried out. The potential biomarkers of the extract in the treatment of insomnia were screened by ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS) combined with multivariate analysis, and the related metabolic pathways were further analyzed. The "component-target-pathway" network was constructed by ultra-high performance liquid chromatography coupled with quadrupole-Exactive mass spectrometry(UHPLC-Q-Exactive-MS/MS) combined with network pharmacology to explore the effective substances and mechanism of Ziziphi Spinosae Semen in the treatment of insomnia. The results of pentobarbital sodium-induced sleep test and histopathological evaluation(hematoxylin and eosin staining) showed that Ziziphi Spinosae Semen extract had good theraputic effect on insomnia. A total of 21 endogenous biomarkers of Ziziphi Spinosae Semen extract in the treatment of insomnia were screened out by serum metabolomics, and the metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, and nicotinate and nicotinamide metabolism were obtained. A total of 34 chemical constituents were identified by UHPLC-Q-Exactive-MS/MS, including 24 flavonoids, 2 triterpenoid saponins, 4 alkaloids, 2 triterpenoid acids, and 2 fatty acids. The network pharmacological analysis showed that Ziziphi Spinosae Semen mainly acted on target proteins such as dopamine D2 receptor(DRD2), 5-hydroxytryptamine receptor 1 A(HTR1 A), and alpha-2 A adrenergic receptor(ADRA2 A) in the treatment of insomnia. It was closely related to neuroactive ligand-receptor interaction, serotonergic synapse, and calcium signaling pathway. Magnoflorine, N-nornuciferine, caaverine, oleic acid, palmitic acid, coclaurine, betulinic acid, and ceanothic acid in Ziziphi Spinosae Semen may be potential effective compounds in the treatment of insomnia. This study revealed that Ziziphi Spinosae Semen extract treated insomnia through multiple metabolic pathways and the overall correction of metabolic disorder profile in a multi-component, multi-target, and multi-channel manner. Briefly, this study lays a foundation for further research on the mechanism of Ziziphi Spinosae Semen in treating insomnia and provides support for the development of innovative Chinese drugs for the treatment of insomnia.
