Objective:To investigate the expression and methylation status of the SALL4 gene in placental tissues of fetal growth restriction (FGR) and its effects on trophoblast cell proliferation, migration, and invasion. Methods:Placental tissues were collected from 20 full-term FGR patients and 20 healthy term controls who underwent regular prenatal examination and cesarean section at the Third Affiliated Hospital, Zhengzhou University between July 2023 and February 2024. SALL4 mRNA and protein expression were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Methylation specific polymerase china reaction (MSP) assessed promoter methylation levels. HTR8/SVneo cells were transfected with SALL4-targeting small interfering RNA (si-SALL4) or negative control small interfering RNA (si-NC). HTR8/SVneo cells were treated with the demethylating agent 5-aza-2′-deoxycytidine (5-Aza-dC) to inhibit gene methylation (5-Aza-dC group) or with 10% RPMI-1640 medium as a vehicle control. Transfection efficiency (for siRNA) and the efficacy of 5-Aza-dC-induced demethylation were assessed by qRT-PCR and Western blot. The functional effects of SALL4 knockdown and methylation inhibition on trophoblast cells were evaluated using proliferation assays, scratch wound healing assays, and Transwell invasion assays. Statistical analyses included independent t-tests and Chi-square test. Results:(1) Human tissues: FGR placentas showed lower SALL4 mRNA (0.802±0.194 vs. 1.015±0.186, t=3.55) and protein expression (0.445±0.114 vs. 0.701±0.113, t=3.19), alongside higher methylation rates of SALL4 [80% (16/20) vs. 15% (3/20), χ2=14.44] compared to controls (all P<0.05). (2) In vitro: si-SALL4 transfection reduced HTR8/SVneo proliferation (OD450 at 48 h: 0.653±0.021 vs. 0.827±0.040, t=6.60), migration [healing rate at 48 h: (24.317±2.637)% vs. (49.327±1.961)%, t=13.18], and invasion [counted invaded cells: (133.000±6.557) vs. (272.667±18.009) cells, t=12.62] versus si-NC (all P<0.05). Conversely, 5-Aza-dC treatment increased HTR8/SVneo proliferation (0.917±0.042 vs. 0.783±0.031, t=－4.47), migration [(71.097±3.354)% vs. (51.632±2.877)%, t=－7.63], and invasion [(384.000±12.166) vs. (202.833±7.095) cells, t=－13.69] versus vehicle control (all P<0.05). Conclusions:Hypermethylation of the SALL4 promoter in FGR placentas suppresses its expression, impairing trophoblast cell function. Demethylation restores SALL4 expression and enhances cellular proliferation, migration, and invasion, involving in the occurrence and development of FGR disease.

The National Essential Medicines System could protect public health and ensure access to essential medications.Although the current selection methods for China's National Essential Medicines Lists(NEMLs)are becoming more scientific and standardized,there are still problems such as much emphasis on expert experience and the lack of transparency of decision-making basis.To address these issues,it proposes an evidence-based decision-making pathway for NEMLs selection guided by clinical value.This approach ensures a strong integration of evidence and decision-making,offering valuable insights for improving the adjustment procedures and selection criteria of the NEMLs in China.

Epilepsy is a chronic neurological disorder that often begins in childhood and can extend over the entire life course; therefore, it is necessary to establish a long-term, systematic life-course management model. Whole life-cycle disease management emphasizes interventions at key points in time and focuses on diagnosis and treatment points at all stages of life and disease processes. Guided by the concept of holism and preventive treatment, this article discussed the application strategies of TCM in the prevention, control, treatment, health and management of epilepsy in children at different stages. In the prevention period, the disease should be prevented first, and early screening should be carried out; in the control period, the disease should be prevented from changing, and the early intervention of Chinese materia medica should be carried out; during the treatment period, the combination of disease and syndrome and dynamic syndrome differentiation by stages were adopted; during the rehabilitation period, the treatment of different diseases with the same treatment should be emphasized to manage the comorbidity and improve the prognosis; in the long-term management period, the prevention and recovery after stroke should be focused on, and the comprehensive management scheme of TCM in the transition period from children to adults should be put forward. This article systematically expounded the role of TCM in improving seizure control rate and prognosis in the whole life-cycle management of childhood epilepsy, and actively explored the construction of the whole process health management system of chronic diseases.

Lipophosphatidic acid(LTA)was used to stimulate Mac-T cells,and the expression lev-els and phosphorylation levels of key proteins of nuclear factor-κB(NF-κB)and mitogen-activated protein kinase(MAPK)signaling pathway and the expression levels of upstream key action factors TLR4 and MyD88 proteins were detected by Western blot,and EDU assay was used to detect cell proliferation levels and flow cytometry was used to detect apoptosis.The results showed that acti-vation of GPR120 significantly decreased the phosphorylation levels of LTA-induced NF-κB(P65 and IκBα)(P＜0.01)and MAPK(JNK,ERK,p38)(P＜0.01)in Mac-T cells;inhibition of GPR120 was able to upregulate LTA-induced NF-κB(p65 and IκBα)in Mac-T cells(P＜0.01)and MAPK(JNK,ERK,p38)phosphorylation levels(P＜0.01);and activation of GPR120 significantly allevia-ted LTA-induced upregulation of TLR4 and MyD88(P＜0.01);inhibition of GPR120 significantly exacerbated LTA-induced upregulation of TLR4 and MyD88(P＜0.05);LTA stimulation led to a trend of diminished Mac-T cell proliferation and significantly increased apoptosis,whereas activa-tion of the GPR120 gene significantly increased cell activity(P＜0.01),promoted cell proliferation and significantly reduced apoptosis(P＜0.05)thereby alleviating the damage to Mac-T cells by LTA;LTA stimulation led to a highly significant increase in apoptosis(P＜0.01).In contrast,acti-vation of the GPR120 gene significantly reversed the increase in the apoptosis rate of Mac-T cells induced by LTA(P＜0.01),while inhibition of the GPR120 gene enhanced the apoptosis-promo-ting effect of LTA(P＜0.05),indicating that activation of the GPR120 gene attenuated the in-crease of apoptosis rate caused by LTA-induced inflammatory Mac-T cells.The results suggest that GPR120 can regulate inflammation by mediating TLR4 and MyD88 expression to inhibit NF-κB/MAPK inflammatory pathway activation and can promote cell proliferation.
