Abstract
On September 26, 2024, a municipal hospital in Jiaxing City reported a maternal case of Listeria monocytogenes infection. In order to clarify the source of infection, the Jiaxing Center for Disease Control and Prevention immediately conducted the epidemiological investigation, laboratory testing and related disposal work. The case presented with fever (37.9 ℃), gradually intensifying paroxysmal abdominal pain without obvious cause, and went to hospital on the day of onset. Due to fetal intrauterine distress, a male infant was delivered by cesarean section on the same day. The epidemiological investigation identified that the case usually consumed fruits, often store fruits such as watermelon and grapes in the refrigerator alongside raw meat, and the refrigerator had never been cleaned or disinfected, posing a risk of cross contamination. Laboratory tests on amniotic fluid sample from the pregnant woman, infant blood sample showed positive results for Listeria monocytogenes infection. One strain of Listeria monocytogenes was detected in a smear sample from the inner wall of the refrigerator, and all the strains were ST2 type. Consuming fruits contaminated with Listeria monocytogenes may be the main source of infection. Food safety education for pregnant women and their family members should be strengthened to reduce the risk of infection.

ObjectiveTo investigate the key targets of Jianpi Yiqi prescription (JYP) in the treatment of hepatocellular carcinoma (HCC) based on network pharmacology and explore the effect of JYP on the invasion and proliferation of hepatocellular carcinoma cells via protein tyrosine phosphatase, non-receptor type 1 (PTPN1) by bioinformatics analysis and CRISPR/Cas9. MethodsThe potential targets of JYP in the treatment of HCC were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), SwissTargetPrediction, GeneCards, NCBI, and CTD. Additionally, the active components of JYP that could interact with PTPN1 were screened out, and then molecular docking between the targets and active components was performed in Autodock 4.0. UALCAN, HPA, and LinkedOmics were used to analyze the expression of PTPN1 in the HCC tissue, and the relationship of PTPN1 expression with the overall survival (OS) of HCC patients was discussed. CRISPR/Cas9 was used to knock down the expression of PTPN1 in HepG2 and SK-hep-1 cells, and the knockdown effect was examined by sequencing, Real-time PCR, and Western blot. HepG2 cells were classified into blank control, low-, medium-, and high-dose JYP (5.25, 10.5, 21 g·kg-1), and PTPN1 knockout groups. Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of PTPN1 in HepG2 cells of each group. The effects of JYP and PTPN1 knockdown on the proliferation, invasion, and apoptosis of HepG2 cells were detected by Cell Counting Kit-8 (CCK-8), Transwell, and Annexin V-FITC/PI methods, respectively. ResultsJYP had the most active components targeting PTPN1, and 31 of the active components had the binding energy less than -5.0 kcal·mol-1 in molecular docking. The mRNA and protein levels of PTPN1 in the HCC tissue were higher than those in the normal tissue (P<0.01). Compared with that in the normal tissue, the mRNA level of PTPN1 in the HCC tissue was up-regulated at the pathological stages Ⅰ-Ⅲ and grades G1-G3 (P<0.01), and it was not significantly up-regulated at the stage Ⅳ or grade G4. The mRNA level of PTPN1 in the TP53-mutated HCC tissue was higher than that in the TP53-unmutated HCC tissue (P<0.01). The high mRNA level of PTPN1 was associated with the OS reduction (P<0.01). After treatment with the JYP-containing serum or knockdown of PTPN1, HepG2 cells demonstrated decreased proliferation and invasion and increased apoptosis (P<0.01). ConclusionPTPN1 may be one of the core targets of JYP in the treatment of HCC. It is highly expressed in the HCC tissue and cells, which is associated with the poor prognosis of patients. The expression level of PTPN1 is significantly up-regulated in the HCC tissue of the patients with TP53 mutation. However, TP53 mutation or deletion does not affect the expression of PTPN1 in HCC cells. JYP can significantly down-regulate the expression of PTPN1 to inhibit the proliferation and invasion and promote the apoptosis of HCC cells.

Chinese Journal of School Health 2025;46(1):53-57
Objective:
To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents.
Methods:
Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents.
Results:
The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01).
Conclusions
Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

Minimally conscious state (MCS) is at the edge between closed and open consciousness, but it still belongs to the category of "wind-strike block" syndrome. The basic pathogenesis of MCS is the obstruction of pathogenic qi, orifices closed and spirit hidden, with pathological factors including phlegm, fire, and blood stasis. Wind movement and water retention may also be present, and often leading to deficiency syndrome due to the exhaustion of qi, blood, yin, and yang at later stages. Treatment chooses Shexiang (Moschus) as the chief medicinal, emphasizing combination of medicinals and urgency of medication administration; the key therapeutic method is to open the orifices, with focuses on expelling pathogens and reinforcing healthy qi. For patients with severe phlegm or fire, use Xiaochengqi Decoction (小承气汤) to open the lower orifices, discharge heat and unblock the bowels, combined with Shexiang (Moschus) and Niuhuang (Bovis Calculus) to open the upper orifices, awaken the spirit and guide qi. For patients with turbid phlegm as the predominant, temporarily replace Shexiang (Moschus) with Baizhi (Angelicae dahuricae radix), using Ditan Decoction (涤痰汤) to eliminate phlegm to open the orifices, when turbid phlegm gradually subsided, Shexiang (Moschus) could be added. For patients with blood stasis as the predominant, Tongqiao Huoxue Decoction (通窍活血汤) will be used to activate blood and open orifice, if the blood circulates, the endogenous wind will be calmed, the water will be induced, the orifices will open and the consciousness will restore. For patients with closed orifices and body deficiency, the treatment should open the orifices and reinforce healthy qi, and consider the root and branch simultaneously; qi deficiency syndrome can be addressed with Buyang Huanwu Decoction (补阳还五汤) to boost qi and reinforce healthy qi; yin deficiency syndrome can be treated with Shaoyao Gancao Decoction (芍药甘草汤) combined with Fengsui Pill (封髓丹) to nourish yin, soften sinews, and secure kidney essence; yang deficiency can be managed by using Dihuang Yinzi Decoction (地黄饮子) to enrich yin, supplement yang, and open the orifices.

ObjectiveTo explore the molecular mechanism by which gypenoside L (Gyp-L) promotes apoptosis and inhibits ovarian cancer (OC) through the FK506-binding protein (FKBP) prolyl isomerase 8 (FKBP8)/B-cell lymphoma-2 (Bcl-2) axis, with the piR-hsa-2804461 pathway as a breakthrough point. MethodsThe effects of different concentrations of Gyp-L and cis-platinum on the proliferation of OVCAR3 cells were determined by the cell count kit-8 method to identify the appropriate intervention concentration for subsequent experiments. OVCAR3 cells were allocated into blank, low-dose Gyp-L (Gyp-L-L, 50 µmol·L-1), high-dose Gyp-L (Gyp-L-H, 100 µmol·L-1), and cis-platinum (15 µmol·L-1) groups. The migration, colony formation, and apoptosis of OVCAR3 cells were detected by the cell scratch assay, colony formation assay, and flow cytometry, respectively. The mRNA levels of piR-hsa-2804461 and FKBP8/Bcl-2 axis-related genes in OVCAR3 cells were determined by Real-time PCR, and the expression levels of FKBP8/Bcl-2 axis-related proteins were determined by simple Western blot. Further, an OVCAR3 cell model with piR-hsa-2804461 knocked out was constructed. The cells were allocated into blank, NC-inhibitor, inhibitor, NC-inhibitor+Gyp-L, and inhibitor+Gyp-L groups. The colony formation of OVCAR3 cells was detected by the colony formation assay. The mRNA levels of piR-hsa-2804461 and FKBP8/Bcl-2 axis-related genes and the expression levels of FKBP8/Bcl-2 axis-related proteins were determined by Real-time PCR and simple Western blotting, respectively. ResultsGyp-L inhibited the migration and proliferation (P<0.01), promoted the apoptosis (P<0.05), up-regulated the mRNA level of piR-hsa-2804461 (P<0.05), and down-regulated the mRNA and protein levels of FKBP8 and Bcl-2 (P<0.05) in OVCAR3 cells. Furthermore, Gyp-L increased the mRNA and protein levels of Bcl-2-associated X protein (Bax), cysteinyl aspartate-specific proteinase (Caspase)-3, and Caspase-9, which are related to the FKBP8/Bcl-2 axis (P<0.05). ConclusionGyp-L may promote apoptosis by regulating the piR-hsa-2804461/FKBP8/Bcl-2 axis, thus affecting the occurrence of ovarian cancer.

ObjectiveTo investigate the role of mature-tRNA-Asp-GTC and pre-tRNA-Arg-TCT in the ferroptosis phenotype of ovarian cancer (OC) cells and the regulatory mechanism of gypenoside L (Gyp-L) on mature-tRNA-Asp-GTC and pre-tRNA-Arg-TCT in OC cells. MethodsThe proliferation of human ovarian adenocarcinoma OVCAR3 cells was detected by cell counting kit-8 (CCK-8) assay, and the half-maximal inhibitory concentration (IC50) values of cisplatin (DDP), Gyp-L, and DDP in the presence of Gyp-L were calculated to determine the intervention concentration for subsequent experiments. Cell cloning assay and scratch assay reflected the proliferation and migration ability of OVCAR3 cells. PANDORA-seq small RNA sequencing was used to detect the differentially expressed transfer RNA-derived small RNAs (tsRNAs) in the cells after Gyp-L intervention, and the corresponding target genes of the tsRNAs were found by the RNAhybrid software. Malondialdehyde (MDA), glutathione (GSH), and lipid peroxide (LPO) levels were measured by colorimetry or enzyme linked immunosorbent assay (ELISA) method, Fe2+ content by FerroOrange fluorescent probe, and reactive oxygen species (ROS) content by DCFH-DA fluorescent probe to reflect the occurrence of ferroptosis in OVCAR3 cells. OVCAR3 cells were divided into a control group, a 50 µmol·L-1 Gyp-L group, and a 100 µmol·L-1 Gyp-L group. Quantitative real-time polymerase chain reaction (PCR) was performed to detect the expression of mature-tRNA-Asp-GTC, mature-tRNA-Leu-CAA, mature-mt_tRNA-Tyr-GTA_5_end, mature-tRNA-Val-CAC, mature-mt_tRNA-Glu-TTC, pre-tRNA-Arg-TCT, mature-tRNA-Asn-GTT, hydroxymethylbilane synthase (HMBS), Wnt, β-catenin, glutathione peroxidase 4 (GPX4), Kelch-like ECH-associated protein 1 (KEAP1), nuclear factor erythroid 2-related factor 2 (Nrf2), activating transcription factor 3 (ATF3), cystine/glutamate antiporter xCT, lysophosphatidylcholine acyltransferase 3 (LPCAT3), and arachidonate 15-lipoxygenase (ALOX15). Western blot was performed to detect the expression of HMBS, Wnt, β-catenin, GPX4, KEAP1, Nrf2, ATF3, xCT, LPCAT3, and ALOX15 proteins. ResultsThe 50 µmol·L-1 Gyp-L, 100 µmol·L-1 Gyp-L, DDP, 50 µmol·L-1 Gyp-L+DDP, and 100 µmol·L-1 Gyp-L+DDP groups showed significantly inhibited proliferation and migration of OVCAR3 cells (P<0.05) and exacerbated cell ferroptosis as reflected by the increase in the content of ROS, MDA, LPO, and Fe2+, as well as a decrease in the content of GSH (P<0.05). Compared with the control group, Gyp-L effectively interfered with the expression of 25 tsRNAs in OVCAR3 cells (P<0.05, |log2Fc|>1). Pre-tRNA-Arg-TCT/HMBS/Wnt/β-catenin/GPX4, pre-tRNA-Arg-TCT/KEAP1/NRF2/xCT, mature-tRNA-Asp-GTC/ATF3/KEAP1/NRF2/xCT, and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 axial expression was significantly aberrant after Gyp-L intervention (P<0.05). ConclusionThe pre-tRNA-Arg-TCT/HMBS/Wnt/β-catenin/GPX4, pre-tRNA-Arg-TCT/KEAP1/Nrf2/xCT, mature-tRNA-Asp-GTC/ATF3/KEAP1/Nrf2/xCT, and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 signaling pathways are involved in OC development. Gyp-L inhibits OC development by activating OVCAR3 cell ferroptosis onset mainly through the mature-tRNA-Asp-GTC/ATF3/KEAP1/Nrf2/xCT and mature-tRNA-Asp-GTC/LPCAT3/ALOX15 signaling axes.
