Objective To explore the value of quantitative analysis of perirenal fat combined with Mayo adhesive probability(MAP)score in predicting the WHO/International Society of Urological Pathology(ISUP)nuclear grade of renal cell carcinoma(RCC).Methods The imaging data of 139 pathologically confirmed RCC patients were retrospectively analyzed.The patients were divided into low-grade group(grade Ⅰ-Ⅱ,n=112)and high-grade group(grade Ⅲ-Ⅳ,n=27)according to the WHO/ISUP nuclear grade.Spearman correlation analysis was used to assess the relationship between fat features and WHO/ISUP nuclear grade.The multivariate logistic regression model was used to detemine the related factors of high-grade RCC,and the area under the curve(AUC)of the receiver operating characteristic(ROC)curve was used to evaluate the diagnostic performance of each parameter.Results The AUC of perirenal adipose tissue(PAT)％alone for evaluating high-grade RCC was the highest,at 0.77[95％confidence interval(CI)0.69-0.83].The stepwise multivariate logistic regression model showed that perinephric fat stranding(PFS)[odds ratio(OR)=34.54,95％CI 7.60-156.87,P＜0.001],PAT％(OR=0.46,95％CI 0.32-0.66,P＜0.001),and tumor location(OR=0.26,95％CI 0.07-0.92,P=0.037)were related factors of high-grade RCC,with an AUC of 0.90(95％CI 0.84-0.94).Conclusion Quantitative analysis of perire-nal fat combined with MAP score can effectively predict the WHO/ISUP nuclear grade of RCC,providing a novel approach for per-sonalized treatment strategies to improve prognosis.

Objective To investigate the different biomechanical effects of two types of palatal expanders and expansion sites on a bi-lateral complete cleft lip and palate(BCCLP)in mixed dentition with a finite element analysis(FEA).Methods The CBCT data of a patient with BCCLP were collected to construct a FEA model containing craniomaxillary suture structure.The fan-shaped and traditional Hyrax expanders were drawn and assembled into the FEA model in SolidWorks software according to the working conditions as follows:condition 1 and 2,the fan-shaped expander was placed at the anterior/posterior part of the palate respectively;condition 3 and 4,the Hyrax expander was placed at the anterior/posterior part of the palate respectively.A 5 N force in X axis direction was loaded at the apex of the expander coil spring.The stress distribution and initial displacement of craniomaxillary complex in four working conditions were compared.Results ①In working condition 1,2 and 3,the displacement of anterior part was larger than the posterior part of the dental arch.Under condition 4,the displacement of anterior,middle and posterior parts of dental arch were basically the same.②The maximum stress and displacement were observed at crowns in all working conditions.③There was a certain skeletal enlargement effect,which showed a gradually decreasing deformation trend from alveolar region to the upward region.Conclusion The expansion effect of fan-shaped expander is more suitable for BCCLP patients with extremely narrow anterior arch and normal posterior arch.For the tradi-tional Hyrax expander,the position has a great influence on expansion effect.It is showed that the dental support expander could pro-duce skeletal dilation effect in BCCLP patients during mixed dentition.

Objective:To investigate the prevalence of infectious diarrhea among older adult patients with schizophrenia, identify the influential factors, and construct a nomogram prediction model for infectious diarrhea.Methods:This study is a prospective cohort study that used convenience sampling to select 160 older patients with schizophrenia from three psychiatric hospitals in Wenzhou (85 cases from Wenzhou Seventh People's Hospital, 40 cases from Lucheng Third People's Hospital, and 35 cases from The Affiliated Kangning Hospital of Wenzhou Medical University) who were admitted between January 2022 and December 2023. The prevalence of infectious diarrhea and its influential factors were statistically analyzed. Regression analysis was conducted to develop a risk prediction model for infectious diarrhea, which was presented using a nomogram.Results:A total of 160 older adult patients with schizophrenia were aged between 61 and 79 years, with an average age of (67.82 ± 7.56) years. Among these patients, 53 were female (33.13%), and 107 were male (66.87%). Thirty-four patients experienced infectious diarrhea, with an incidence rate of 21.25%. Univariate analysis revealed significant differences in body mass index ( χ2 = 9.36, P = 0.009), history of diarrhea ( χ2 = 4.52, P = 0.033), disinfection of tableware ( χ2 = 4.16, P = 0.04), handwashing before and after meals ( χ2 = 6.11, P = 0.013), intestinal flora disorder ( χ2 = 19.43, P < 0.001), CD 4+/CD 8+ ratio ( t = 12.37, P < 0.001), interleukin-17 ( t = 15.86, P < 0.001), and fecal secretory IgA ( t = 20.18, P < 0.001) in older adult patients with schizophrenia. Multifactorial analysis indicated that body mass index ( OR = 0.733), disinfection of tableware ( OR = 0.733), handwashing before and after meals ( OR = 0.452), CD 4+/CD 8+ ratio ( OR = 0.359), interleukin-17 ( OR = 0.563), and fecal secretory IgA ( OR = 0.455) were protective factors against infectious diarrhea in older adult patients with schizophrenia (all P < 0.05). Conversely, a history of diarrhea ( OR = 1.774) and intestinal flora disorder ( OR = 1.528) were identified as risk factors for infectious diarrhea in this population (both P < 0.05). Conclusions:The influential factors for the occurrence of infectious diarrhea in older adult patients with schizophrenia include body mass index, history of diarrhea, disinfection of tableware, handwashing before and after meals, intestinal flora disorder, CD 4+/CD 8+ ratio, interleukin-17, and fecal secretory IgA levels. Future studies should conduct longitudinal research to optimize the prediction model and establish a dynamic nomogram model. This will provide nurses with a reliable tool for dynamically predicting the occurrence of infectious diarrhea in older adult patients with schizophrenia, with the aim of reducing the incidence of infectious diarrhea and improving the patients' quality of life.

Objective:To explore the effect of fibroblast growth factor 2(FGF2)on ferroptosis of renal fibrotic cells and its po-tential molecular mechanisms.Methods:Rat NRK-52E cells were randomly divided into control group,renal fibrosis model group,FGF2 cytokine stimulation group,knockdown empty plasmid group,si-FGF2 group,overexpression empty plasmid group,overexpres-sion FGF2 group,Fer-1 treatment group.The model group was treated with TGF-β1 to obtain a renal fibrosis cell model.Cellular im-munofluorescence method was used to measure the level of cell fibrosis.Western blot was used to detect ferroptosis-related proteins(Nrf2,GPX4 and SLC7A11)and pathway proteins(STAT3,p-STAT3)expression level in the cells.Results:Knockdown of FGF2 could alleviate the increase in α-SMA and Collagen Ⅲ proteins caused by TGF-β1 stimulation of renal tubular cells(P<0.05).FGF2 could promote the activation of STAT3 protein into p-STAT3.The expression level of SLC7A11 protein was significantly increased after FGF2 cytokine stimulation(P<0.05).Compared with the control group,the expressions of Nrf2 and GPX4 in renal fibrotic cells in the si-FGF2 group and Fer-1 treated group were significantly reduced(P<0.05).In addition,knockdown of FGF2 significantly reduced in-terstitial fibrosis of renal tubular epithelial cells(P<0.05).Conclusion:FGF2 may mediate TGF-β1-induced renal ferroptosis through the STAT3/SLC7A11 signaling pathway,and knock down of FGF2 can improve fibrosis of renal tubular epithelial cells.

Background:Optimizing cultivation techniques for traditional Chinese medicine has become a crucial means to improve the quality of medicinal materials.Microbial agents,as environmentally friendly and efficient plant growth promoters and soil conditioners,have increasingly attracted attention in eco-agriculture research.Objective:Our understanding remains limited regarding how the application of microbial agents,alone or in combination,affects changes in the rhizosphere microbiome and its association with the bioactive components of medicinal materials.Methods:In this study,Epimedium pubescens Maxim.was employed as a model plant to examine the effects of 2 microbial agents(Paenibacillus mucilaginosus and Bacillus subtilis)applied individually and in combination on plant growth and the accumulation of bioactive components.Additionally,this study explored the relationship between the rhizosphere microbiome and plant development.Results:The application of microbial agents increased the yield of E.pubescens leaves by 20.30％to 33.66％and enhanced the total flavonol glycosides content by 11.40％to 29.94％.Meanwhile,microbial treatments reshaped the rhizosphere microbiome,promoted the enrichment of beneficial microorganisms(e.g.,Frankia and Paenibacillus),suppressed phytopathogenic fungi such as Didymella and Scytalidium,and enhanced the stability of the soil microbial co-occurrence network.The partial least squares path model suggested that microbial agents not only directly impact the quality of medicinal herbs but also indirectly alter the accumula-tion of bioactive components by modulating the soil microbiome.Conclusion:These findings deepen our understanding of the relationship between medicinal plant quality and rhizosphere micro-biomes as mediated by microbial agents.They also provide a basis for designing and manipulating synthetic microbial communities to promote sustainable development in eco-agriculture.

Based on the concept of "regulating the five zang organs and harmonizing the spleen and stomach"， globus hystericus is believed to originate from dysfunction of the five zang organs and disharmony of the spleen and stomach. Treatment primarily focuses on regulating the spleen and stomach while also considering other affected organs， with a self-prescribed Anpiwei Jingyan Formula （安脾胃经验方） for harmonizing the spleen and stomach as the foundational treatment. Additionally， syndrome-based modifications are applied according to imbalances in the heart， lung， kidney， or liver. For heart-yang deficiency， modified Linggui Zhugan Decoction （苓桂术甘汤） could be combined； for heart-yin deficiency， modified Tianwang Buxin Pill （天王补心丹） could be combined. For lung failing to disperse and descend and fluid retention， modified Sanao Decoction （三拗汤） could be combined； for lung and stomach yin deficiency， modified Shashen Maidong Decoction （沙参麦冬汤） could be combined. For kidney-yang deficiency with ascending counterflow of cold water， modified Jingui Shensi Pill （金匮肾气丸） could be combined； for kidney-yin deficiency， modified Liuwei Dihuang Pill （六味地黄丸） could be combined. For liver constraint and spleen deficiency， modified Sini Powder （四逆散） could be combined； for liver-yin deficiency or liver stagnation transforming into fire and attacking the stomach， modified Yiguan Decoction （一贯煎） could be combined.

As an intermediate phenotype for multiple cardiovascular diseases, left ventricular hypertrophy (LVH) benefits from early diagnosis, which allows for timely intervention to prevent worsening of the condition, mitigate severe complications like heart failure and arrhythmias, and consequently improve patient outcomes. Preliminary advances have been made using deep learning for the early diagnosis and identification of etiology in LVH. This paper reviews the pathophysiology, causes, and diagnostic standards for LVH, discusses the strengths and weaknesses of applying deep learning to diagnostic tools such as echocardiography, cardiac magnetic resonance imaging, and electrocardiogram, examines its use in prognostic evaluation, and concludes by summarizing current achievements and suggesting future research avenues.
