ObjectiveTo investigate the mechanism of action of modified Shaofu Zhuyutang in antagonizing cellular pyroptosis and fibrosis in ectopic endometrial tissues of endometriosis through the Toll-like receptor 4/nuclear factor-κB/NOD-like receptor protein 3 (TRL4/NF-κB/NLPR3) signaling pathway. MethodsSeventy-two SPF-grade female SD rats were randomly divided into a sham-operated group (n = 12) and a modeling group (n = 60). The rats in the sham-operated group underwent a caesarean section, while the rats in the modeling group were used to establish an endometriosis model through the auto-transplantation method. After successful modeling, the animals were randomly divided into the model group, progesterone group (0.25 mg·kg-1), and modified Shaofu Zhuyutang low-, medium-, and high-dose groups (7.5, 15, 30 g·kg-1), with 12 animals in each group. After 4 weeks of drug administration, voluntary activity and heat pain latency were observed. The rats were sacrificed for tissue collection, and Masson staining were used to observe histopathological changes in the endometrial tissues. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of interleukin-18 (IL-18), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and transforming growth factor-β (TGF-β). Immunohistochemistry (IHC) was used to detect the protein expression area of tumor necrosis factor-related factor 6 (TRAF6) and NLPR3 in the endometrial tissues. Immunofluorescence (IF) was used to detect the relative fluorescence intensity of Caspase-1 and gasdermin D (GSDMD) in the endometrial tissues. Western blot was employed to measure the relative expression of TRL4, myeloid differentiation factor 88 (MyD88), TRAF6, NF-κB p65, phosphorylated NF-κB p65 (p-NF-κB p65), and NLPR3 proteins in endometrial tissues. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of TRL4, MyD88, TRAF6, NF-κB, and NLPR3 in the endometrial tissues. ResultsCompared with the sham-operated group, rats in the model group showed reduced voluntary activity and shorter heat pain latency. Serum levels of IL-18, IL-1β, TNF-α, and TGF-β were elevated. The relative expression areas of TRAF6 and NLPR3 proteins were increased, and the relative fluorescence intensity of Caspase-1 and GSDMD was enhanced. The relative expression of TRL4, MyD88, TRAF6, NF-κB p65, p-NF-κB p65, and NLPR3 proteins, along with the expression of TRL4, MyD88, TRAF6, NF-κB, and NLPR3 mRNA, were significantly increased (P<0.01). Compared with the model group, rats in the progesterone group and the modified Shaofu Zhuyutang medium- and high-dose groups exhibited improved voluntary activity, longer heat pain latency, the fibrosis of endometrial tissue is alleviated. Serum levels of IL-18, IL-1β, TNF-α, and TGF-β were decreased. The relative expression areas of TRAF6 and NLPR3 proteins decreased, and the relative fluorescence intensity of Caspase-1 and GSDMD weakened. The relative expression of TRL4, MyD88, TRAF6, p-NF-κB p65, NLPR3 proteins, and TRL4, MyD88, TRAF6, NF-κB, and NLPR3 mRNA expression were reduced (P<0.05, P<0.01). ConclusionModified Shaofu Zhuyutang may play a therapeutic role in endometriosis by interfering with key proteins in the TRL4/NF-κB/NLPR3 signaling pathway, reducing NLRP3 inflammasome-induced cellular pyroptosis, antagonizing the fibrosis process in ectopic endometrial tissues, improving the inflammatory microenvironment in the pelvic cavity, and alleviating pain.

ObjectiveTo observe the effects of modified Shaofu Zhuyutang on key proteins of the epidermal growth factor receptor (EGFR)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway in SD rats with endometriosis. MethodsAfter successful establishment of an endometriosis model in 60 female SD rats of SPF grade via the auto-transplantation method, the rats were randomly divided into a model group, modified Shaofu Zhuyutang high-, medium-, and low-dose groups, and a gestrinone group, with another 12 rats serving as a blank group. The blank and model groups were administered 10 mL·kg-1 normal saline, while the high-, medium-, and low-dose groups received 30, 15, and 7.5 g·kg-1 modified Shaofu Zhuyutang, respectively. The gestrinone group was administered 0.25 mg·kg-1 gestrinone suspension. After four weeks of treatment, uterine contractions were induced with 2 U of oxytocin, and the writhing response of rats was observed. After 24 h, the rats were euthanized, and the weight and volume of ectopic endometrial tissue were recorded. Hematoxylin-eosin (HE) staining was used to observe pathological changes in endometrial tissues, while the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay was used to evaluate the apoptosis rate of endometrial tissues. Immunofluorescence was used to detect the relative expression areas of the B-cell lymphoma-2 gene-associated promoter (Bad) and B-cell lymphoma-2 (Bcl-2) proteins in endometrial tissues. Serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), epidermal growth factor (EGF), and EGFR were measured by enzyme-linked immunosorbent assay (ELISA). The relative protein expression levels of EGFR, PI3K, phosphorylated PI3K (p-PI3K), Akt, and phosphorylated Akt (p-Akt) in endometrial tissues were analyzed by Western blot. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression levels of EGFR, PI3K, and Akt. ResultsCompared with the blank group, the model group showed endometrial thickening, glandular and mesenchymal hyperplasia, a significant decrease in the relative expression area of Bad in ectopic endometrial tissues, a significant increase in the relative expression area of Bcl-2, and a significant reduction in the apoptosis rate as indicated by TUNEL staining. Serum levels of IL-1β, IL-6, TNF-α, EGF, and EGFR were significantly elevated (P<0.01). The relative protein expression levels of EGFR, PI3K, p-PI3K, Akt, and p-Akt, as well as the mRNA expression levels of EGFR, PI3K, and Akt, were also significantly increased (P<0.01). Compared with the model group, the high- and medium-dose groups of modified Shaofu Zhuyutang and the gestrinone group exhibited reduced glandular and mesenchymal hyperplasia to varying degrees, with dilated glandular lumens. The number of writhing responses was significantly reduced, the latency to writhing response was significantly prolonged, and the weight and volume of ectopic endometrial tissue were significantly decreased. The relative expression area of Bad in ectopic endometrial tissue was significantly increased, the relative expression area of Bcl-2 was significantly decreased, and the apoptosis rate was significantly elevated as shown by TUNEL staining. Serum levels of IL-1β, IL-6, TNF-α, EGF, and EGFR were significantly reduced, and the relative protein expression levels of EGFR, PI3K, p-PI3K, Akt, and p-Akt, as well as the mRNA expression levels of EGFR, PI3K, and Akt, were significantly decreased (P<0.05,P<0.01). ConclusionModified Shaofu Zhuyutang may exert therapeutic effects on endometriosis by interfering with key proteins of the EGFR/PI3K/Akt signaling pathway and inducing apoptosis in ectopic endometrial tissue.

AIM: To assess the stability of the tear film and the characteristics of corneal nerves in patients with Parkinson's disease(PD).METHODS: This cross-sectional observational study included 72 PD patients and 50 healthy controls. Disease severity was determined using the Hoehn-Yahr(H-Y)scale, dividing patients into mild and moderate PD groups. Dry eye symptoms were evaluated via the ocular surface disease index(OSDI)questionnaire, while tear secretion was quantified using the Schirmer I test. Ocular surface damage was assessed through staining scores, and comprehensive ocular examinations were performed utilizing the LipiView ocular surface interferometer and an ocular surface analyzer. Corneal nerve parameters were examined using corneal confocal microscopy in conjunction with automated analysis software ACCMetrics, with correlations drawn between these parameters, PD course, and severity.RESULTS: PD patients exhibited significantly elevated OSDI scores, indicative of more pronounced dry eye symptoms compared to the control group(F=70.290, P<0.01). Tear film stability was markedly compromised, with significantly shorter tear film breakup time and increased corneal fluorescein staining, both showing statistically significant differences relative to controls(all P<0.01). Tear secretion indices, including Schirmer I test results and tear meniscus height, were significantly reduced in PD patients(all P<0.01), whereas lipid secretion indices, such as lipid layer thickness and meibomian gland dropout score, did not show significant variation. Corneal nerve analysis revealed significant reductions in corneal nerve fiber density, nerve branch density, fiber length, and total branch density in PD patients compared to controls(all P<0.01). Furthermore, blink frequency was markedly prolonged(F=62.353, P<0.01). Correlation analysis demonstrated a significant relationship between alterations in tear film stability and both disease duration and H-Y scores.CONCLUSION: PD patients have obvious dry eye manifestations in the early stage of the disease, including the reduction of tear film stability and corneal nerve fiber density, and gradually aggravate with the progress of the disease. Neurodegenerative disease-related dry eye needs to be diagnosed early and actively treated.

Objective:To understand the status of intestinal helminth infections in Lunan area of Shandong Province (Jining City, Rizhao City, Linyi City, Heze City, and Zaozhuang City), and provide scientific basis for formulating parasitic disease prevention and control strategies.Methods:From 2016 to 2023, a stratified sampling method was used to conduct surveillance in 33 counties (cities, districts, hereinafter referred to as counties) in Lunan area of Shandong Province. Each county was divided into five areas (east, south, west, north, and center), with one administrative village (community) selected from each area. And ≥200 permanent residents (aged ≥3 years old, having lived locally for ≥6 months) were sampled from each village (community), and one stool sample was collected from each participant. The Kato-Katz method (two slides per sample) was used for parasite detection, and the results were analyzed.Results:From 2016 to 2023, a total of 49 436 people were surveyed, including 23 861 males and 25 575 females, with an age range of 3 - 105 years old. The testing identified 687 intestinal helminth infections, with an overall infection rate of 1.39%. The predominant infection was whipworm (582 cases), with an infection rate of 1.18%; followed by roundworm and hookworm, with infection rates of 0.13% (62 cases) and 0.05% (23 cases) respectively; other types of helminths ( Clonorchis sinensis and pinworm) totaled 20 cases, with an infection rate of 0.04%. From 2016 to 2023, the annual intestinal helminth infection rates were 2.76% (201/7 292), 0.90% (56/6 327), 0.84% (52/6 200), 1.70% (124/7 282), 1.23% (88/7 133), 1.45% (104/7 150), 0.34% (17/5 058), and 1.46% (45/3 084), showing an overall downward trend (χ 2trend = 42.40, P < 0.001). The ≥60 age group had the highest intestinal helminth infection rate (2.39%, 323/13 489), while the 30 - 39 age group had the lowest rate (0.68%, 48/7 016). There was statistically significant difference in infection rates among different age groups (χ 2 = 172.25, P < 0.001). There was no statistically significant difference in infection rates between genders (χ 2 = 0.03, P = 0.862). Farmers had the highest infection rate (1.69%, 560/33 118), with statistically significant differences among different occupational groups (χ 2 = 64.88, P < 0.001). Those with primary school education or below had the highest infection rate (1.82%, 445/24 469), with statistically significant differences among different education levels (χ 2 = 64.93, P < 0.001). Conclusions:In Lunan area of Shandong Province, whipworm is the predominant intestinal helminth infection, with elderly people being the high-risk group. Although the intestinal helminth infection rate in this region remains at a low level, there is still a risk of transmission. Continuous surveillance is needed, along with strengthened prevention and control measures for key populations.

Background: Epimedii Folium, first recorded in the Shennong’s Classic of Materia Medica (Shen Nong Ben Cao Jing), is a traditional Chinese medicine (TCM) known for its effects of “benefiting Qi and strengthening the heart.” Icariside II (ICS II) is one of the main active components of Epimedii Folium, possessing cardiovascular protective and anti-inflammatory properties. However, the potential mechanisms of ICS II on myocardial ischemia (MI) remain unclear. Objective: The aim of the study was to investigate the effects and preliminary molecular mechanisms of ICS II in treating isoproterenolinduced MI in rats. Methods: A rat model of MI was established by subcutaneous injection of isoproterenol. Electrocardiography, echocardiography, myocardial enzymes analysis, heart weight index, triphenyltetrazolium chloride staining, histopathology, TUNEL staining, RT-qPCR, and Western blot were employed to evaluate the effects and preliminary molecular mechanisms of ICS II on MI rats. Results: Pharmacodynamic studies suggested that ICS II inhibited ST-segment elevation in electrocardiograms, improved cardiac function, reduced heart weight index and myocardial enzyme levels, decreased myocardial infarct size, alleviated cardiac histological damage, and inhibited apoptosis, thereby exerting cardioprotective effects in MI rats. Further studies revealed that ICS II may partially inhibit the expression of NLRP3/Caspase-1 axis-related targets at both protein and mRNA levels. Conclusions: Our findings indicate that ICS II exerts anti-MI effects, and its preliminary molecular mechanisms may be related to inhibiting the activation of the NLRP3/Caspase-1 axis to alleviate inflammatory responses.

Objective:To evaluate the causal relationship between autism spectrum disorder (ASD) and chronic pancreatitis (CP) using a bidirectional two-sample Mendelian randomization (MR) analysis.Methods:Based on genome-wide association study (GWAS) data, forward and reverse two-sample MR analyses were conducted to examine the causal relationship between ASD and CP. Single-nucleotide polymorphisms (SNPs) reaching genome-wide significance were selected from the GWAS data as candidate instrumental variables, and the Steiger directionality test was used to confirm the causal direction. The inverse-variance weighted (IVW) method was applied as the primary analysis to estimate the causal effect of the exposure on the outcome. MR-Egger regression and weighted median methods were used as supplementary sensitivity analyses to assess the robustness of the results. Pleiotropy and heterogeneity tests were performed to evaluate the reliability of the findings.Results:The forward MR analysis ultimately identified 29 SNPs. The IVW analysis indicated that ASD had a significant positive causal effect on CP risk ( OR=1.197, 95% CI 1.047-1.368, P=0.008), with no evidence of horizontal pleiotropy or significant heterogeneity. In the reverse MR analysis, 17 SNPs were included; the IVW analysis did not detect a significant causal effect of CP on ASD ( OR=0.990, 95% CI 0.935-1.047, P=0.717), also with no evidence of horizontal pleiotropy or significant heterogeneity. Causal effect estimates from MR-Egger regression and weighted median analyses were generally consistent with those of IVW. Conclusions:These findings indicate that, at the level of genetic susceptibility, ASD is a risk factor for CP.
