Objective To translate the Maternal Childbirth Fatigue Perception Questionnaire(MCFQ)into Chinese and examine its reliability and validity among women undergoing vaginal deliv-ery.Methods Following the Brislin translation model,the MCFQ was translated,back-translated,culturally adapted and pre-tested to develop a Chinese version.By using the convenience sampling method,574 parturients were selected for a questionnaire survey from January to April 2024,and the reliability and validity of the Chinese questionnaire were evaluated.Results The Chinese version of MCFQ consisted of 3 dimensions and 13 items,namely physical fatigue(7 items),perceived fatigue(3 items)and emotional fatigue(3 items).The item-level content validity index ranged from0.813 to 1.000,and the scale-level content validity index was 0.938.The overall Cronbach's α coefficient of the scale was 0.870,and the split-half reliability coefficient was 0.848.Confirmatory factor analysis demonstrated that the question naire had a good fit.Conclusion The Chinese version of MCFQ has good reliability and validity and can be used as an effective tool to assess the fatigue level of parturients during the delivery process.It is helpful for clinical medical staff to optimize the management of the la-bor process,improve the quality of delivery,and ensure the safety of mothers and infants.

Objective:To explore the effect of training transfer intervention based on dynamic transfer model (DTM) on standardized training for newly recruited nurses, and to provide reference for the establishment of standardized training transfer intervention strategies for newly recruited nurses.Methods:The quasi-experimental method was used in this study.The convenience sampling method was used to select the newly recruited nurses of Zhengzhou Central Hospital Affiliated to Zhengzhou University as the research subjects.According to the entry time, the newly recruited nurses in July 2020 were selected as the control group ( n=50), and the training and effect evaluation was carried out according to the hospital regulations and "training syllabus for newly recruited nurses (trial)". The newly recruited nurses in July 2021 were taken as the experimental group ( n=60), and on the basis of the control group, the experimental group implemented the DTM training transfer intervention program for training. The scores of personal training transfer effect, general self-efficacy and organizational training transfer atmosphere were compared between the two groups immediately, 3 months and 6 months after training. Results:There were 11 males and 39 females in the control group; aged (24.80 ± 2.11) years old.And there were 14 males and 46 females in the experimental group;aged (24.40 ± 1.75) years old.After training, the total score of transfer effect of individual training in experimental group was (17.73 ± 1.56), (19.47 ± 1.92) and (22.30 ± 1.49) immediately after training, at 3 months and 6 months after training, and (15.84 ± 1.57), (15.98 ± 1.55) and (16.08 ± 1.55) in the control group respectively. The differences were statistically significant ( t=-6.32, -10.36 and -21.42, all P<0.05). Before and after the two groups of training, there were statistically significant differences among groups, within groups, and interactions ( F=137.10, 241.64 and 170.17, all P<0.05). After training, the general self-efficacy scores of the experimental group were (27.10 ± 1.81), (28.03 ± 1.85) and (29.05 ± 1.70) immediately after training, at 3 months and 6 months, respectively, which were higher than (26.28 ± 2.42), (26.36 ± 2.86) and (26.90 ± 2.87) of the control group. The differences were statistically significant ( t=-2.03, -3.95 and -4.87, all P<0.05). Before and after the two groups of training, there were statistically significant differences among groups, within groups and interactions ( F=7.64, 71.26 and 30.25, all P<0.05). After training, the total organizational training transfer atmosphere scores of the experimental group were (39.35 ± 1.96), (50.38 ± 3.17) and (51.47 ± 3.28) immediately after training, respectively, higher than (38.08 ± 2.63), (38.48 ± 2.36) and (38.66 ± 2.27) of the control group. The differences were statistically significant ( t=-2.89, -21.94 and -23.35, all P<0.05), and before and after the two groups of training, there were statistically significant differences among groups, within groups, and interactions ( F=419.75, 261.56 and 207.99, all P<0.05). Conclusions:DTM-based training transfer intervention can improve the effect of personal training transfer, enhance the sense of self-efficacy and create a positive atmosphere of organizational training transfer, and effectively guide new nurses to apply the learning content to clinical practice after standardized training, and improve the effect of training transfer.

The transition of cancer cells from epithelial state to mesenchymal state awarded hepatocellular carcinoma (HCC) stem cell properties and induced tumorigenicity, drug resistance, and high recurrence rate. Reversing the mesenchymal state to epithelial state by inducing mesenchymal-epithelial remodeling could inhibit the progression of HCC. Using high-throughput screening, chrysin was selected from natural products to reverse epithelial-mesenchymal transition (EMT) by selectively increasing CDH1 expression. The target identification suggested chrysin exerted its anti-HCC effect through covalently and specifically binding threonine 205 (Thr205) of alpha-enolase (ENO1). For the first time, we revealed that ENO1 bound β-catenin mRNA, and recruited YTHDF2 to identify the m6A modified β-catenin in the 3'-UTR region to degrade β-catenin mRNA. Eventually, the CDH1 gene expression was improved through the regulation of β-catenin mRNA. ENO1/β-catenin mRNA interaction might be a promising target for cellular plasticity reprogramming. Moreover, chrysin could mediate mesenchymal‒epithelial remodeling through increasing degradation of β-catenin mRNA by promoting the binding of ENO1 and β-catenin mRNA. To the best of our knowledge, chrysin is the first reported small molecule inducing β-catenin mRNA degradation through binding to ENO1. The water-soluble derivative of chrysin may be a natural product-derived lead compound for circumventing metastasis, recurrence, and drug resistance of HCC by mediating mesenchymal‒epithelial remodeling.

Objective:To investigate whether kisspeptin can influence the maternal-fetal interface regulatory T cells(Treg),thereby participating in the pathogenesis of recurrent spontaneous abortion(RSA).Methods:Normal pregnancy(NP)and RSA mice models were established,where NP mice received a tail vein injection of PBS(NP-PBS group),and RSA mice received a tail vein in-jection of PBS(RSA-PBS group)and active fragment of kisspeptin KP10(RSA-KP10 group),observing embryo absorption rates.Im-munohistochemistry was employed to assess expressions of kisspeptin and Foxp3 in mice uterine tissues.Peripheral blood Treg cells were isolated and expanded through magnetic bead separation.Intervention with KP10 and KP234(kisspeptin receptor antagonist)was administered,and flow cytometry was used to detect levels of IL-10 and TGF-β1 secretion by Treg cells,as well as differences in proliferation and apoptosis.RNA-Seq transcriptomic sequencing was conducted on uterine tissues from RSA-PBS group and RSA-KP10 group of mice.Differentially expressed genes(DEGs)were subjected to GO,KEGG and GSEA enrichment analyses.Results:Embryo absorption rate in RSA mice was higher than that in NP mice,the embryo absorption rate was decreased after tail vein injec-tion of KP10.Expressions of kisspeptin and Foxp3 in uterus of RSA mice was lower than that in NP mice,while increased after injec-tion of KP10.Kisspeptin could modulate the secretion of IL-10 and TGF-β1 by Treg cells,influencing their proliferation without affect-ing apoptosis.Enrichment analysis results showed that DEGs were mainly enriched in reproductive structure development,IL-17,and TGF-β signaling pathways.Conclusion:Kisspeptin can influence both the quantity and function of Treg cells,offering a new theoreti-cal foundation for investigating the pathogenesis and treatment of RSA.

Objective:To investigate the correlation of combined detection of p16 and Rb with high-risk human papilloma virus (HR-HPV) infection in non-oropharyngeal squamous cell carcinoma (NOPSCC) of the head and neck.Methods:A total of 68 NOPSCC cases of the head and neck (23 cases of the nasal cavity and paranasal sinuses and 45 cases of larynx) with complete clinical and pathological data, diagnosed at the Beijing Tongren Hospital, Capital Medical University, Beijing, China from November 2013 to December 2023, were collected. The expression of p16 and Rb was detected using immunohistochemistry of the EnVision two-step method, while the HR-HPV mRNA expression was detected using in situ hybridization. The concordance, sensitivity, and specificity of p16 alone and the combined detection of p16 and Rb for detecting HR-HPV infection were analyzed.Results:Among the 68 patients with NOPSCC, 53 were male and 15 were female, with a median age of 63.5 (range, 57.3 to 66.8) years. 41 patients had a smoking history and 27 did not. 33 patients had an early T stage (T1/T2) and 35 had advanced T stage (T3/T4). 14 patients had lymph node metastasis and 2 had distant metastasis. Histological types included 62 cases of keratinized squamous cell carcinoma, 5 cases of non-keratinized squamous cell carcinoma, and 1 case of basal-like squamous cell carcinoma. 25 cases were positive for p16. Among the 25 cases, 16 cases were positive for Rb, and 6 cases were positive for HR-HPV mRNA. 43 cases were negative for p16, including 38 cases positive for Rb and no cases positive for HR-HPV mRNA. The concordance between p16 and HR-HPV mRNA expression was poor ( Kappa=0.285, P=0.001), with a sensitivity of 100.0% and specificity of 69.4%. In contrast, the combined detection of p16+/Rb- showed high concordance with HR-HPV mRNA expression ( Kappa=0.719, P<0.001), with a sensitivity of 100.0% and specificity of 95.2%. Conclusions:In NOPSCC of the head and neck, the combined detection of p16 and Rb may be used as a marker for assessing HR-HPV infection. Recognizing the p16+/Rb- expression pattern in NOPSCC can improve the specificity of HR-HPV detection.

Objectives To investigate the clinical efficacy on combined application of ear canal injected administration dispenser and triamcinolone acetonide econazole nitrate cream in the treatment of mycosis externa.Methods Clinical data of 130 patients(166 ears)diagnosed with mycosis externa from January 2023 to December 2023 were collected and randomly divided into two groups.In the observation group,65 cases(86 ears)were treated with ear canal injected administration dispenser combined with triamcinolone acetonide econazole nitrate cream,while in the control group,65 cases(80 ears)applied clean cotton swabs with triamcinolone acetonide econazole nitrate cream to the external auditory canal by themselves to treat mycosis externa.All the patients were treated for 4 weeks and followed up for half a year.The clinical efficacy,recurrence rate and adverse reactions were statistically analyzed and compared.Results The total effective rate of the observation group was 97.67%,which was significantly higher than that of the control group was 73.75%,there was a significant difference between the two groups(P<0.05).There were no obvious adverse reactions in either group.No obvious recurrence was observed in the recovered patients of both groups during the follow-up period.Conclusion The efficacy of combined of ear canal injected administration dispenser and triamcinolone acetonide econazole nitrate cream in the treatment of mycosis externa is significant.Compared with the traditional way of medicine application,the adverse reactions are less.It can improve the cure rate and reduce the recurrence rate,which is worthy in clinical application.

This study investigated the effects and underlying mechanisms of the luteolin-naringenin combination(LN)on liver injury induced by acetaminophen(APAP).Forty-eight Kunming mice were randomly allocated into six groups:a normal control group,an APAP-induced liver injury model group,a positive drug treatment group,and three LN treatment groups with low,medium,and high doses.After the final drug administration,the mice were fasted for 12 hours prior to eu-thanasia for sample collection.Serum transaminase activity,oxidative stress indices,and hematoxy-lin-eosin(HE)staining were assessed to evaluate the effects of LN on APAP-induced hepatic inju-ry.Additionally,Western blot analysis was conducted to examine the expression levels of sphingo-sine kinase 1(SPHK1)and endoplasmic reticulum stress(ERS)-related proteins,thereby elucida-ting the potential mechanisms by which LN mitigates APAP-induced liver injury.The results dem-onstrated that varying concentrations of LN effectively ameliorated serum aminotransferase activi-ty and oxidative stress levels induced by APAP in a dose-dependent manner.Histopathological ex-amination via HE staining revealed significant improvement in APAP-induced liver tissue injury following treatment with different concentrations of LN.Furthermore,Western blot analysis indi-cated that the protein expressions of SPHK1,CHOP,p-IRE1α,ATF6,p-PERK,p-eIF2α,and ATF4 were markedly reduced after administration of various concentrations of LN.The results demonstrate that LN exhibits a significant protective effect against APAP-induced liver injury by inhibiting the SPHK1-mediated aberrant expression of ERS-related molecules.This study high-lights the importance of targeting SPHK1 in the treatment of APAP liver injury and provides a no-vel therapeutic approach through the multi-target and multi-pathway combination of monomers.

Objective To investigate the awareness of female patients with pelvic floor dysfunction regarding minimally invasive laser treatment of the reproductive tract and analyze the factors influencing their decision-making intentions,this study aims to provide a foundation for early treatment of pelvic floor dysfunction and further development in reproductive health management.Methods A convenience sampling method was employed to select 164 female patients with pelvic floor dysfunction who sought treatment at the Pelvic Rehabilitation Center of Dongguan Maternal and Child Health Care Hospital between June 2023 and August 2024.The study utilized the Female Sexual Function Index,Incontinence Quality of Life Questionnaire,and Family Support Self-Assessment Scale to conduct a survey.Binary logistic stepwise regression analysis was conducted to investigate the factors influ-encing patients'inclination towards undergoing genital laser minimally invasive treatment.Results Among the 164 female patients,143(87.2%)expressed an intention to receive treatment,with 22.6%demonstrating a rela-tively clear understanding of genital laser minimally invasive treatment.Logistic regression analysis revealed that occupation significantly influenced treatment intention(P<0.05).Compared to healthcare professionals,individuals in the teaching profession(OR=10.81,95%CI:1.04～112.21),self-employed individuals(OR=20.34,95%CI:3.46～119.43),and those in other professions(OR=16.26,95%CI:4.05～65.29)were more inclined to express willingness for undergoing treatment.Furthermore,a lower score on the Incontinence Quality of Life scale was found to positively correlate with treatment intention(OR=0.96,95%CI:0.93～0.99).Conclusion Although patients express a high intention to undergo minimally invasive genital laser treatment,their overall awareness of the procedure remains insufficient.

BACKGROUND: The American Heart Association recently released a new cardiovascular health (CVH) metric, Life's Essential 8 (LE8), for health promotion. However, the association between LE8 scores and the risk of chronic kidney disease (CKD) remains uncertain. We aimed to explore the association of LE8 scores with new-onset CKD and examine whether socioeconomic deprivation and genetic risk modify this association. METHODS: A total of 286,908 participants from UK Biobank and without prior CKD were included between 2006 and 2010. CVH was categorized using LE8 scores: low (LE8 scores <50), moderate (LE8 scores ≥50 but <80), and high (LE8 scores ≥80). The study outcome was new-onset CKD, ascertained by data linkage with primary care, hospital inpatient, and death data. Cox proportional hazard regression models were used to investigate the association between CVH categories and new-onset CKD. RESULTS: During a median follow-up of 12.5 years, 8857 (3.1%) participants developed new-onset CKD. Compared to the low CVH group, the moderate (adjusted hazards ratio [HR], 0.50; 95% confidence interval [CI]: 0.47-0.53) and high CVH (adjusted HR, 0.31; 95% CI: 0.27-0.34) groups had a significantly lower risk of developing new-onset CKD. The population-attributable risk associated with high vs. intermediate or low CVH scores was 40.3%. Participants who were least deprived ( vs.  most deprived; adjusted HR, 0.75; 95% CI: 0.71-0.79) and with low genetic risk of CKD ( vs.  high genetic risk; adjusted HR, 0.89; 95% CI: 0.85-0.94) had a significantly lower risk of developing new-onset CKD. However, socioeconomic deprivation and genetic risks of CKD did not significantly modify the relationship between LE8 scores and new-onset CKD (both P -interaction >0.05). CONCLUSION Achieving a higher LE8 score was associated with a lower risk of developing new-onset CKD, regardless of socioeconomic deprivation and genetic risks of CKD.
