ObjectiveTo analyze the clinical treatment plan and traditional Chinese medicine （TCM） medication rule of children with primary nephrotic syndrome （PNS） in the First Affiliated Hospital of Henan University of Chinese Medicine. MethodsThe gender and age of children firstly diagnosed with nephrotic syndrome in the pediatric nephrology department of the First Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to December 2022 were collected， and the use of immunosuppressive agents and related frequencies were counted. According to the inclusion and exclusion criteria， an independent TCM prescription database for children with nephrotic syndrome was established. Excel was used to analyze the relevant information of the literature. The frequency counting， association rule analysis， and cluster analysis were carried out on TCM in the prescription， and the high-frequent drugs were analyzed. Results（1） General information： A total of 711 children were included， consisting of 522 males （73.42%） and 189 females （26.58%）. The ratio of male to female was about 2.76∶1. The disease mainly occurred in infants and preschool age， and the average age of onset was （4.74 ± 3.48） years old. （2） Clinical treatment plan and use of immunosuppressive agents： Of the 711 children with PNS， 237 were treated with hormone alone （32.33%）， and 474 （66.67%） received immunosuppressive agents combined with hormones. In the initial treatment， hormone combined with Tacrolimus （TAC） was the preferred treatment （32.91%）. For children with refractory PNS who exhibited poor clinical efficacy， Rituximab （RTX） was mostly used for treatment， with a ratio of up to 23.63%. （3） TCM syndrome and medication rule： In PNS syndrome differentiation， Qi and Yin deficiency was identified as the main syndrome. This involved a total of 477 cases， accounting for 67.09%. Yang deficiency of spleen and kidney was observed in 118 cases， accounting for 16.60%. A total of 711 children were included， of which 706 children were treated with TCM. This involved a total of 706 prescriptions， 226 TCM， and 9 793 frequencies. There were 30 herbs used more than 95 times. The top five TCM were Radix et Rhizoma Glycyrrhizae （81.16%）， Radix Astragali （71.81%）， Poria （68.84%）， Rhizoma Atractylodis Macrocephalae （63.60%）， and Fructus Corni （57.37%）. The drug association rules and network diagram showed that the combination of ''Radix Astragali-Rhizoma Atractylodis Macrocephalae-Poria'' was the closest， and five types of combinations were obtained by cluster analysis. ConclusionIn the diagnosis and treatment of PNS in children， TAC combined with hormones shows good clinical efficacy and high safety. For children with refractory PNS， RTX combined with hormones can be used. TCM medication for PNS should follow the basic principles of strengthening the body and vital Qi and make good use of drugs such as Radix Astragali， Poria， Rhizoma Atractylodis Macrocephalae， and cornus to regulate the Yin and Yang balance and achieve better clinical efficacy.

Objective To investigate the effects of fructose exposure on mitochondrial oxidative damage in M2-type macrophages and elucidate the regulatory role of protein phosphatase 2A(PP2A)in the process using its specific activator ABL127,an inhibitor of protein phosphatase methylesterase-1(PPME-1).Methods ① Immortalized mouse bone marrow-derived macrophages Ana-1 were subjected and grouped into M0(conventional culture),M2(treated with 20 ng/mL IL-4 for 24 h),and M2+Fru groups(IL-4 plus 0.04,0.20,1.00,or 5.00 mmol/L fructose).Cell viability was assessed with CCK-8 assay.Number of mitochondria,total and mitochondrial levels of reactive oxygen species(ROS),and mitochondrial membrane potential(ΔΨM)were measured using fluorescent probes.Total and demethylated PP2Ac protein levels were detected by Western blotting.② Ana-1 cells were also divided into M0,M2,M2+Fru(20 ng/mL IL-4+5.00 mmol/L fructose,24 h),and M2+Fru+ABL127(20 ng/mL IL-4+5.00 mmol/L fructose+1.00 μmol/L ABL127,24 h)to investigate PP2A-mediated mechanisms.Numbers of mitochondria and lysosomes,ROS level,and ΔΨM were detected via fluorescence assays.Expression of mitophagy-related proteins,PTEN induced putative kinase 1(PINK1),P62,microtubule-associated protein light chain 3(LC3),and voltage-dependent anion channel(VDAC)was evaluated by Western blotting,and the mRNA levels of M2 markers,found in inflammatory zone 1(Fizz1),arginase-1(Arg-1),and TGF-β were measured using RT-qPCR.Results ① Compared with the M2 group,fructose treatment at a concentration ranging from 0.04 to 5.00 mmol/L showed no effect on cell viability in M2 macrophages,but increased total ROS level in a dose-dependent manner(P<0.05).Fructose of 5.00 mmol/L resulted in significantly elevated mitochondrial ROS and mitochondrial quantity(P<0.05),reduced ΔΨM(P<0.05),up-regulated demethylated-PP2Ac(P<0.05),and no changed total-PP2Ac protein level.② Compared with the M2+Fru group,the addition of ABL127 led to decreased number of mitochondria but increased number of lysosomes(P<0.01),up-regulation of PINK1,LC3Ⅱ and VDAC proteins,down-regulation of P62(P<0.05),reduced total and mitochondrial ROS levels,and enhanced ΔΨM(P<0.01).The mRNA expression of Fizz1,Arg-1,and TGF-β was notably decreased in the M2+Fru group than the M2 group(P<0.05),and the levels were rescued by ABL127 treatment(P<0.05).Conclusion Fructose induces PP2Ac demethylation and then mitochondrial oxidative damage in M2-type macrophages.PP2A activation promotes mitophagy and reverses fructose-induced damage.

Objective:To retrieve and summarize the best evidence for cognitive function improvement in Alzheimer's disease patients, so as to provide reference for clinical practice.Methods:Following the "6S" evidence model, guidelines, expert consensus, clinical decision, and systematic reviews on cognitive function improvement in Alzheimer's disease patients were systematically retrieved from domestic and foreign databases and websites. The search keywords included "Alzheimer's disease, cognitive function, improvement". Evidence-based nursing methods were used to evaluate the quality of literature and extract evidence. The search period was from July 1, 2000 to July 31, 2024.Results:A total of 15 articles were included, including five guidelines, four expert consensus, two clinical decision, and four systematic reviews. Sixteen pieces of best evidence were summarized from four aspects of evaluation and identification, pharmacological intervention, non-pharmacological intervention, and caregiver support.Conclusions:Patients with Alzheimer's disease require timely identification of symptoms related to cognitive impairment and assessment using standardized scales. Multiple intervention methods, such as pharmacological intervention, non-pharmacological intervention, and caregiver support, should be used to enhance patients' quality of life. Evidence application should be tailored to each patient's specific circumstances through individualized selection and adjustment to ensure the effectiveness and scientific rigor of cognitive function improvement strategies, thereby facilitating the translation of optimal evidence into clinical practice.

The diagnosis of osteoporosis is mainly characterized by reduced bone mineral density(BMD).Commonly used BMD examination methods are dual-energy X-ray absorptiometry and quantitative CT,but their distribution is not enough.Routine clinical CT can also be used for BMD assessment,which mainly includes vertebral body CT values and BMD values obtained based on asynchronous calibration and internal calibration technology,which is expected to achieve opportunistic osteoporosis screening and fracture risk prediction.This paper reviews the application of routine clinical CT in assessing BMD of osteoporosis patients,in order to help clinicians and scholars understand the current status and future research directions of opportunistic osteoporosis screening.

Objective To investigate the effect of leucine carboxyl methyltransferase 1(LCMT1)knockout on fructose-induced lipid deposition in primary mouse hepatocytes.Methods Primary hepatocytes were isolated from wild-type(WT)and hepatocyte-specific LCMT1 knockout(KO)mice via a two-step hepatic portal vein perfusion method.The cells were divided into four groups:WT-control group,WT-fructose group,KO-control group,and KO-fructose group.Cell viability was determined through Alamar-Blue assays.Hepatocyte injury was evaluated based on alanine aminotransferase and aspartate aminotransferase levels.Lipid deposition was visualized via Oil Red O staining and lipid droplet green fluorescence staining,and the cellular triglyceride content was quantified via a GPO-POD assay.The mRNA expression of lipid metabolism-related genes was detected via quantitative real-time PCR,and the protein expression of LCMT1 and PP2Ac was detected via Western blot.Results Fructose treatment did not alter cell viability significantly in any group,and no significant cell damage was observed(P＞0.05).The WT-fructose group exhibited greater accumulation of lipid droplets in hepatocytes than that in the WT-control group(P＜0.001),with significantly elevated triglyceride contents(P＜0.05).The mRNA levels of the de novo lipid synthesis genes ChREBP,SREBP-1c,and ACC1 were increased significantly(P＜0.05,P＜0.001,P＜0.001),whereas FAS expression did not differ significantly between groups(P＞0.05).The mRNA levels of the lipid uptake genes FABP1 and FATP2 also increased significantly(both P＜0.05).In contrast,the KO-fructose group presented a reduced number of lipid droplets(P＜0.01,P＜0.001),decreased triglyceride content(P＜0.05),and decreased mRNA levels of ChREBP,SREBP-1c,ACC1,FABP1,and FATP2(P＜0.01,P＜0.001,P＜0.001,P＜0.001,P＜0.05);CPT1 mRNA levels were markedly increased(P＜0.01).Total PP2Ac expression was significantly higher(P＜0.05)and PP2Ac demethylation was significantly lower(P＜0.01)in the WT-fructose group than in the WT-control group.In the KO-control group,total PP2Ac expression remained unchanged(P＞0.05),whereas PP2Ac demethylation was markedly elevated(P＜0.001).Compared with levels in the WT-fructose group,the KO-fructose group presented markedly lower total PP2Ac expression and significantly higher PP2Ac demethylation levels(P＜0.05,P＜0.01,respectively).Conclusions LCMT1 knockout alleviates fructose-induced lipid deposition in primary hepatocytes by inhibiting lipid uptake,increasing fatty acid oxidation,and downregulating de novo lipid synthesis.These effects are medicated by the LCMT1 knockout-mediated upregulation of PP2Ac demethylation,thereby modulating PP2A activity.

Objective:This study investigated the underlying causes of discordance between multiplex fluorescence polymerase chain reaction (PCR)-capillary electrophoresis in determining MSI and immunohistochemistry (IHC) for mismatch repair (MMR) protein evaluation in gastrointestinal adenocarcinomas, aiming to improve interpretation accuracy and guide clinical precision treatment strategies.Methods:A retrospective analysis was conducted on 511 surgically resected or biopsied specimens (161 gastric adenocarcinomas and 350 colorectal adenocarcinomas) diagnosed at the Department of Pathology, Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January to June 2024. MMR protein expression of tumors was evaluated by IHC, while MSI status was assessed using the 2B3D National Cancer Institute (NCI) Panel through multiplex fluorescence PCR-capillary electrophoresis on tumor DNA and matched normal DNA. The concordance between the two methods was analyzed, and factors contributing to the discordance were investigated. Cases with unstable dinucleotide loci only in the 2B3D NCI Panel, focal MMR protein loss, or unexplained discrepancies underwent validation using the non-NCI Panel through multiplex fluorescence PCR-capillary electrophoresis markers or next-generation sequencing (NGS).Results:In the 511 gastrointestinal adenocarcinomas, the results of the two methods were discordant in 15 cases (2.9%), with a significantly higher discordantrate in gastric cancers (7.5%, 12/161) compared to colorectal cancers (0.9%, 3/350; P＜0.001). Key contributors to the discordance included: sampling limitations (6 cases), 2B3D NCI Panel design constraints (3 cases),tumor heterogeneity (3 cases),isolated MSH6 deficiency (1 case),and unexplained discrepancies (2 cases).Validation studies demonstrated that cases with dinucleotide-only instability showed concordance with IHC after using the non-NCI Panel through multiplex fluorescence PCR-capillary electrophoresis and NGS verifications. Specimens with focal MMR protein loss and unexplained discrepancies aligned with initial PCR results upon NGS validation. Unexplained cases harbored Kirsten rat sarcoma class Ⅰ variants and multiple class Ⅱ genetic alterations. Conclusions:Colorectal adenocarcinoma demonstrated higher concordance between PCR-capillary electrophoresis and IHC than gastric adenocarcinoma.Discordant results require systematic evaluation including technical review, specimen quality control, and supplemental NGS analysis to resolve discrepancies.

Objective To investigate the expression and clinical significance of long non-codingRNA HCG11 (lncRNA HCG11) mRNA and microRNA (miR)-4465 in patients with triple-negative breast cancer(TNBC). Methods The clinicopathological data of 110 TNBC patients hospitalized in Jiulong Hospital of Suzhou from June 2017 to June 2020 were collected,and the clinical significance of the expression of lncRNA HCG11mRNA and miR-4465 was analyzed. Results The expression of lncRNA HCG11 mRNA (1.81±0.53) in cancer tissues was higher than that in adjacent tissues (0.87±0.13),while the expression of miR-4465 (0.68±0.14) was lower than that in adjacent tissues (1.09±0.18),and the differences were statistically significant(t=18.066,18.857,all P<0.05). The results of Pearson analysis showed that lncRNA HCG11mRNA was negatively correlated with the expression of miR-4465 (r=-0.443,P<0.001). The proportion of patients with high expression of lncRNA HCG11mRNA and low expression of miR-4465 in cancer tissues with lymph node metastasis in TNM stage Ⅲ+Ⅳ was higher than that in TNM stage Ⅰ+Ⅱ,and the proportion of patients without lymph node metastasis was higher (x2=6.614,18.510;8.093,22.976,all P<0.05) The 3-year survival rate of lncRNA HCG11mRNA patients with high expression was lower than that of lncRNA HCG11mRNA patients with low expression,and the 3-year survival rate of patients with high expression of miR-4465 was higher than that of patients with low expression of miR-4465 (Log-rank x2=14.45,13.39,all P<0.05). The proportion of patients with clinical stage Ⅲ+Ⅳ in death group was higher than that in survival group (x2=12.667,18.026,all P<0.05). LncRNA HCG11mRNA(HR=2.623,95％CI:1.344～5.118) was risk factors for 3-year death in TNBC patients,while miR-4465(HR=0.891,95％CI:0.821～0.967) was a protective factor (P<0.05). Conclusion The high expression of lncRNA HCG11 mRNA and the low expression of miR-4465 in triple negatire breast cancer were related to the clinicopathological characteristics and prognosis of patients,and are expected to become prognostic marker for TNBC.
