Polygonum multiflorum (PM), a commonly used Chinese herbal medicine in clinical practice, has been associated with frequent reports of liver injury in recent years, and the medication safety of PM has attracted more and more attention in China and globally. This article reviews the recent research advances in the signaling pathways and mechanisms of PM in causing drug-induced liver injury (DILI) and aims to provide new ideas for the proper and rational use of PM in clinical practice. The results show that PM is involved in the regulation of various signaling pathways, and it leads to the death of hepatocytes by destroying mitochondrial function, exacerbating bile acid accumulation, and inducing immune response, oxidative stress, and endoplasmic reticulum stress, thereby inducing the development and progression of DILI through multiple targets, pathways, and levels.

ObjectiveTo investigate the association between urinary thallium (TL) and nonalcoholic fatty liver disease (NAFLD). MethodsRelated data were collected from the registered participants aged ≥18 years in National Health and Nutrition Examination Survey from 2017 to 2020, with th exclusion of the individuals with a lack of liver transient elastography data and urinary TL indicators and those with hepatitis B, hepatitis C or significant alcohol consumption. A total of individuals were divided into NAFLD group and non-NAFLD group. Urinary TL level was quantitatively measured using high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry and online solid-phase extraction combined with isotope dilution. The two groups were compared in terms of age, sex, race, marital status, education, family income poverty impact ratio (FMPIR), body mass index (BMI), smoking, alcohol consumption, diabetes mellitus (DM), hypertension (HTN), hyperlipidemia (HL), and urinary TL level. The independent-samples t test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. Descriptive analysis, multivariable Logistic regression, restricted cubic spline regression analysis, subgroup analysis, and interaction analysis were conducted to investigate the risk association between urinary TL and NAFLD. ResultsA total of 2 511 individuals were included, with 1 612 (64.20%) in the NAFLD group and 899 (35.80%) in the non-NAFLD group, and the NAFLD group had a significantly higher urinary TL level than the non-NAFLD group [0.18 (0.11 — 0.26)μg/L vs 0.16 (0.09 — 0.25)μg/L, Z=-2.76, P=0.01]. After adjustment for the covariates of age, sex, race, education, marital status, FMPIR, BMI, smoking, alcohol consumption, DM, HTN, and HL, the urinary TL Q4 group had a significant increase in the risk of NAFLD (odds ratio [OR]=1.90, 95% confidence interval [CI]: 1.48 — 2.44, P<0.01). There was a positive dose-response relationship (P<0.01) and a non-linear relationship (P<0.01) between urinary TL and the risk of NAFLD. A significant interaction was observed between urinary TL and smoking/BMI (P<0.05). For individuals taking ≥100 cigarettes in their lifetime, the risk of NAFLD was increased by 50% for every quartile increase in urinary TL (OR=1.50, 95%CI: 1.24 — 1.80), and for individuals taking<100 cigarettes in their lifetime, the risk of NAFLD was increased by 20% for every quartile increase in urinary TL (OR=1.20, 95%CI: 1.03 — 1.40); for individuals with a BMI of ≥30 kg/m2, the risk of NAFLD was increased by 30% for every quartile increase in urinary TL (OR=1.30, 95%CI: 1.05 — 1.70), with a statistical significance (P<0.05). ConclusionUrinary TL level is significantly associated with the risk of NAFLD.

Objective:Analyzing the epidemic trends and spatio-temporal distribution characteristics of condyloma acuminatum in China from 2018 to 2023.Methods:Data of condyloma acuminatum cases and incidence rate including 31 provinces (autonomous regions and municipalities) from 2018 to 2023 were collected through the National Notifiable Infectious Disease Reporting System of China Information System for Disease Control and Prevention. Incidence trend analysis was conducted using Joinpoint 4.9.1 software, and spatial autocorrelation analysis using ArcGIS 10.5 software. Spatio-temporal scanning analysis was carried out with SaTScan 10.1.2 software.Results:The incidence rate of condyloma acuminatum declined from 7.26 per 100 000 in 2018 to 7.19 per 100 000 in 2023. The average annual percent change was -0.26%, which was no statistically significant downward trend ( t=-0.26, P=0.806). A significant positive global spatial autocorrelation was observed in the county-level incidence rate across the country, with the global Moran's I ranging from 0.55 to 0.60 (all P<0.001); the Getis-Ord General test statistic Z( G) was all >1.96, indicating a high-value clustering pattern in the reported incidence rate of condyloma acuminatum. The local spatial autocorrelation analysis detected 256, 244, 246, 284, 308, and 315 hotspots each year, which were mainly located in the provinces of Zhejiang, Fujian, Guangdong, Guizhou, Yunnan and Chongqing. Spatio-temporal scanning analyses identified 76 statistically significant spatiotemporal clusters covering 25 provinces (autonomous regions and municipalities). Conclusions:From 2018 to 2023, the reported incidence rate of condyloma acuminata in China exhibited a mild decline. The distribution of hotspot areas and spatiotemporal clusters was largely consistent, primarily in the southeastern coastal and southwestern regions.

OBJECTIVE
To explore the mechanisms of the flavonoids from new "Zhe Eight Flavors" Quzhou Fructus Aurantii(PTFC) against hepatocellular carcinoma based on the prediction of network pharmacology and experimental verification.
METHODS
From TCMSP, TCMID, ETCM, BATMAN-TCM and SwissTargetPrediction databases, the potential target proteins of PTFC, including naringin, narirutin and neohesperidin were collected. Based on the GeneCards, CTD, Disgenet, and OMIM databases, a set of target proteins for hepatocellular carcinoma was constructed. Taking the intersection of potential target proteins of PTFC and target proteins of hepatocellular carcinoma, key target proteins were obtained and a protein-protein interaction network was established. Besides, GO function and KEGG pathway enrichment analysis on the core target proteins was performed and a Compounds-Targets-Pathways-Disease network was constructed. Through proliferation, cloning, wound healing, and migration experiments, the effects of PTFC on the viability of HepG2 liver cancer cells were analyzed. Using fluorescence probe staining the impacts of PTFC on the mitochondrial membrane potential and apoptosis of HepG2 were observed. Finally, the validation of the regulatory effect of PTFC on the key predicted target PRKCA were carried out through RT-qPCR.
RESULTS
Based on network pharmacology, a total of 217 potential target proteins for PTFC were screened, with 59 intersecting target proteins related to diseases, including ALB, ESR1, PRKCA, and others. GO functional and KEGG pathway enrichment analysis revealed that the PTFC target proteins were involved in 193 biological processes and 13 cancer-related signaling pathways. Experimental results demonstrated that PTFC could impact the proliferation, cloning, wound healing, and migration abilities of liver cancer cells, leading to a decrease in mitochondrial membrane potential and promoting cell apoptosis. The results of RT-qPCR confirmed a significant downregulation of PRKCA expression by PTFC, validating the predictions made by network pharmacology analysis.
CONCLUSION
This study has revealed the potential molecular mechanism of PTFC treating hepatocellular carcinoma via the PRKCA target, laying the foundation for clinical application of PTFC.

Background::In vitro fertilization (IVF) has emerged as a transformative solution for infertility. However, achieving favorable live-birth outcomes remains challenging. Current clinical IVF practices in IVF involve the collection of heterogeneous embryo data through diverse methods, including static images and temporal videos. However, traditional embryo selection methods, primarily reliant on visual inspection of morphology, exhibit variability and are contingent on the experience of practitioners. Therefore, an automated system that can evaluate heterogeneous embryo data to predict the final outcomes of live births is highly desirable. Methods::We employed artificial intelligence (AI) for embryo morphological grading, blastocyst embryo selection, aneuploidy prediction, and final live-birth outcome prediction. We developed and validated the AI models using multitask learning for embryo morphological assessment, including pronucleus type on day 1 and the number of blastomeres, asymmetry, and fragmentation of blastomeres on day 3, using 19,201 embryo photographs from 8271 patients. A neural network was trained on embryo and clinical metadata to identify good-quality embryos for implantation on day 3 or day 5, and predict live-birth outcomes. Additionally, a 3D convolutional neural network was trained on 418 time-lapse videos of preimplantation genetic testing (PGT)-based ploidy outcomes for the prediction of aneuploidy and consequent live-birth outcomes.Results::These two approaches enabled us to automatically assess the implantation potential. By combining embryo and maternal metrics in an ensemble AI model, we evaluated live-birth outcomes in a prospective cohort that achieved higher accuracy than experienced embryologists (46.1% vs. 30.7% on day 3, 55.0% vs. 40.7% on day 5). Our results demonstrate the potential for AI-based selection of embryos based on characteristics beyond the observational abilities of human clinicians (area under the curve: 0.769, 95% confidence interval: 0.709–0.820). These findings could potentially provide a noninvasive, high-throughput, and low-cost screening tool to facilitate embryo selection and achieve better outcomes. Conclusions::Our study underscores the AI model’s ability to provide interpretable evidence for clinicians in assisted reproduction, highlighting its potential as a noninvasive, efficient, and cost-effective tool for improved embryo selection and enhanced IVF outcomes. The convergence of cutting-edge technology and reproductive medicine has opened new avenues for addressing infertility challenges and optimizing IVF success rates.

Objective:
To provide high-quality clinical evidence of the efficacy of Tibetan medicine Honghua Ruyi (HHRY) pills for endometriosis-associated dysmenorrhea.
Methods:
This study constitutes a multicenter, randomized, double-blind, placebo-controlled trial encompassing a three-menstrual cycle intervention followed by a three-menstrual cycle follow-up period. A total of 164 eligible females with endometriosis-associated dysmenorrhea were randomly divided into HHRY pills and placebo groups in a 1:1 ratio. The primary outcome included dysmenorrhea symptoms assessed using Visual Analog Scale (VAS) scores and quality of life, whereas the secondary outcome measures included the maximum VAS for non-menstrual pelvic pain, duration of pain episodes (in days), frequency and quantity of the consumption of ibuprofen sustained-release capsules (or other non-steroidal anti-inflammatory drugs), and days off work/study for staff/student due to dysmenorrhea, ovarian cyst, and/or pelvic nodule size. The safety was monitored throughout the treatment period. All the analyses were based on the intention-to-treat principle. For continuous outcomes, simple or multiple linear regressions were used to estimate the differences between the HHRY pills and placebo groups, with categorical data expressed as the number and percentage of occurrences. Differences were compared using the chi-square test or Fisher's exact test. The predefined analysis was adjusted for concomitant treatment, a variable considered to be associated with outcomes but unaffected by treatment allocation. Estimates of treatment effects were reported with 95% confidence intervals. Two-tailed P values ≤ .05 were considered statistically significant.
Conclusion
Positive results from this trial, upon completion would provide robust evidence for the efficacy and safety of HHRY pills in treating dysmenorrhea in patients with endometriosis.
