Chronic glomerulonephritis （CGN） is a common clinical chronic glomerular disease caused by autoimmune reaction， the pathogenesis of which is complex and has not been fully elucidated. There is no specific treatment method in modern medicine. The establishment of an animal model of CGN in accordance with its characteristics in western medicine and traditional Chinese medicine will help to reveal the pathogenesis of CGN， rate drugs， and improve the treatment plan. Based on the clinical diagnostic criteria of CGN， the paper establishes the syndrome differentiation criteria of CGN for Chinese and western medicine. Through summarizing the literature on animal models of CGN and making a further analysis， it is found that the CGN models are mainly modeled using rats with the methods of single-factor induction or two-factor induction， and the main manifestation of the disease characteristics is nephritis-related symptoms. The single-factor-induced or two-factor-induced CGN rat models have a high fitting degree with the clinical characteristics in western medicine， but the fitting degree is insufficient with the clinical characteristics in traditional Chinese medicine. In addition， the CGN models with syndromes of traditional Chinese medicine are dominated by Qi deficiency in the spleen and kidney and Qi deficiency in the lung and kidney， while models for Yang deficiency in the spleen and kidney， Yin deficiency in the liver and kidney， and deficiency of both Qi and Yin are slightly insufficient. Therefore， it is important to prepare a new and improved animal model of CGN， so that a preclinical model can be provided for the exploration of the pathogenesis of CGN in western medicine and traditional Chinese medicine and its therapeutic research.

Objective To investigate the relationship between serum IL-8,homocysteine(Hey),C-reactive protein(CRP)levels and severity of coronary lesions in patients with coronary heart disease(CHD)complicated by chronic heart failure(CHF),as well as their prognostic value.Methods A total of 118 elderly eligible patients admitted to our hospital from January 2023 to September 2024 were prospectively recruited,and according to their Gensini score,they were divided into mild,moderate and severe stenosis groups(45,50 and 23 cases,respectively).Accord-ing to the clinical outcomes after follow-up,they were divided into a good prognosis group(82 cases)and a poor prognosis group(36 cases).The serum levels of IL-8,Hcy and CRP were com-pared among the three groups of different stenosis,and Pearson correlation analysis was used to examine the relationship between the three indicators and the severity of coronary lesions.Cox regression analysis was performed to identify factors influencing poor prognosis in patients with CHD and CHF,and receiver ROC curve analysis was conducted to assess the diagnostic value of serum IL-8,Hey,and CRP levels in predicting prognosis.Results The serum levels of IL-8,Hey and CRP were gradually decreased in the severe,moderate and mild stenosis groups in turn,with statistical significances(P＜0.05).Pearson correlation analysis indicated that serum IL-8,Hcy,and CRP levels were positively correlated with the severity of coronary lesions in the patients with CHD and CHF(r=0.364,0.355,0.372,P＜0.01).Significant differences were found in age,NT-proBNP,D-D,IL-8,Hcy,and CRP levels between the good and poor prognosis groups(P＜0.05).Cox regression analysis revealed that age,NT-proBNP,D-D,IL-8,Hcy,and CRP were influencing factors for poor prognosis in patients with CHD and CHF(P＜0.05).ROC curve ana-lysis showed that the AUC value of IL-8,Hey,CRP,and their combination in predicting prognosis was 0.698,0.714,0.723 and 0.899,respectively.Conclusion In the patients with CHD and CHF,serum IL-8,Hcy,and CRP levels are associated with the severity of coronary lesion and prognosis.Moreover,combining these three indicators has significant diagnostic value for predicting patient outcomes.

Objective:To analyze the characteristics of Hashimoto thyroiditis(HT)and Graves disease(GD),two autoimmune thyroid diseases aged 10-59 in Qingdao City from 2022 to 2024,and to provide scientific basis for making targeted prevention and treatment measures.Methods:A cross-sectional study design was adopted,based on the data of the Regional Health Information Platform in Qingdao,the con-firmed cases of HT and GD from 2022 to 2024 were included,and combined with the data of the seventh population census,the three-year and annual prevalence rates of HT and GD were calculated,and the time trend of annual prevalence was analyzed by Cochran-Armitage trend test.The distribution characte-ristics of HT and GD prevalence in different age groups and regions were analyzed,and Chi-square test was used to compare the differences between the groups.Results:The total number of HT patients among women aged 10-59 in Qingdao City from 2022 to 2024 was 40 362.The proportion of HT patients in 30-34 years old was the highest(19.83％).The proportion of HT patients in Huangdao District was the highest(17.72％).The three-year prevalence of HT was 1 206.53/100 000.In 2022-2024,the annual prevalence of HT increased significantly(P＜0.001),from 385.32/100 000 in 2022 to 1 206.32/100 000 in 2024.The three-year prevalence of HT was significantly different in age distribution(P＜0.001).The three-year prevalence of HT in 25-29 years(2 354.44/100 000)and 35-39 years(2 022.20/100 000)was higher than that in other age groups,showing a bimodal distribution.There were significant differences in the three-year prevalence of HT in different regions(P＜0.001),among which the three-year prevalence of HT in Shinan District was the highest(2 392.90/100 000),followed by Licang Dis-trict(1 492.41/100 000),and Laixi City was the lowest(659.940/100 000).The total number of GD patients was 2 095,among which the proportion of GD patients in the 35-39 age group was the highest(15.42％),and the proportion of GD patients from Jimo District was the highest(12.27％).From 2022 to 2024,the three-year prevalence rate of GD was 62.63/100 000,and the annual prevalence rate of GD showed an increasing trend(P＜0.001),from 20.33/100 000 in 2022 to 62.63/100 000 in 2024.There were significant differences in the prevalence of GD by age(P＜0.001).The three-year prevalence of GD reached the highest value in the 25-29 age group(98.90/100 000),followed by the 35-39 age group(85.21/100 000),and the lowest in the 10-14 age group(14.43/100 000).In the regional distribution,there were significant differences in the 3-year prevalence of GD(P＜0.001).Laoshan District had the highest three-year prevalence of GD(107.58/100 000),followed by Shinan District(97.83/100 000)and Huangdao District(28.92/100 000).Conclusion:The three-year pre-valence of HT and GD in females aged 10-59 years in Qingdao City from 2022 to 2024 is low,but the annual prevalence is on the rise,and the three-year prevalence of HT and GD in females aged 25-39 years is higher than that in other age groups,so it is necessary to strengthen the screening and monitoring of this population.

Objective To elucidate the functional role and underlying mechanisms of the ribosome biogenesis factor BMS1 in neuroblastoma(NB)cellular proliferation.Methods We utilized the R2 genomics analysis and visualization platform to analyze the correlation between BMS1 expression levels and clinical characteristics of NB children.The BMS1 mRNA level in three human neuroblastoma cells SK-N-BE(2),BE(2)-C,IMR-32 and two normal cells hTERT RPE-1,IMR-90 was detected by real-time quantitative polymerase chain reaction(RT-qPCR).Two distinct small interfering RNA(siRNA)sequences were used to target BMS1 mRNA in NB cells SK-N-BE(2)and BE(2)-C,with normal cells hTERT RPE-1 serving as controls.We used RT-qPCR to quantify the mRNA levels of BMS1 and two key neuroblastoma-associated molecules(MYCN and p53).After transfection with siRNA,cellular proliferation was detected by various experimental approaches:crystal violet staining,real-time cell analysis(RTCA),colony-forming unit assay and immunofluorescence.Results By analyzing two independent neuroblastoma clinical cohorts(GSE85047/NRC-283 and Westermann-144 datasets),it was found that the BMS1 mRNA level in MYCN-amplified NB was significantly higher than that in MYCN-non-amplified NB(P<0.05).Furthermore,the overall survival rate of NB children in the BMS1 high-expression group was decreased(P<0.05).Consistent with these clinical observations,the BMS1 mRNA level in NB cells SK-N-BE(2),BE(2)-C and IMR-32 was significantly higher than that in normal cells hTERT RPE-1,IMR-90(P<0.05).The targeted transient knockdown of BMS1 in NB cell lines SK-N-BE(2)and BE(2)-C resulted in decreased intracellular MYCN mRNA expression levels(P<0.05),significantly reduced cell proliferation capacity and colony-forming ability(P<0.05).Immunofluorescence revealed that the expression of Ki-67,a proliferation marker,was decreased(P<0.05).At the molecular level,RT-qPCR showed that the p53 mRNA level was significantly elevated in the BMS1-knockdown groups(si BMS1-1#and si BMS1-2#)compared with the control group(P<0.05).However,transient knockdown of BMS1 had no significant impact on the proliferative capacity of normal cells hTERT RPE-1.Conclusion BMS1 expression was up-regulated in MYCN-amplified NB and negatively correlated with the prognosis of the NB children.Mechanistically,interfering with BMS1 expression may transcriptionally activate p53 in NB cells,thereby inhibiting their proliferative ability,while having minimal impact on normal cells growth kinetics.These findings suggest that BMS1 serves as an important proliferation driver in NB and is expected to be a promising therapeutic target for NB children,particularly MYCN-amplified pediatric patients.

Objective To explore the function of olfactomedin domain family protein 3(OLFM3)in neuroblastoma(NB).Methods The relationship between the expression of OLFM3 mRNA and v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog(MYCN)amplification status and the prognosis of patients in NB clin-ical samples were clarified by using R2 Genomics Analysis and Visualization Platform.Depmap database was used to examine the expression level of OLFM3 in different tumors cell lines and to identify the correlation between OLFM3 expression and MYCN amplification status in various NB cell lines.RT-qPCR and Western blot were used to detect the knockdown level of OLFM3.Cell proliferation was monitored using crystal violet staining and real?time cellular analysis.The colony formation ability of NB cells was assessed using colony?forming unit assay.Results Analysis of R2 database revealed higher level of OLFM3 expression in MYCN?amplified NB clinical samples(P<0.001).Patients with high OLFM3 expression showed a significantly lower overall survival probability compared to those with low OLFM3 expression(P<0.05).Analysis with Depmap database revealed that the expres?sion level of OLFM3 was higher in NB than that in other kind of tumor.The expression level of OLFM3 was signifi?cantly higher in the MYCN?amplified cell lines than in the MYCN?non?amplified cell lines(P<0.01).In MYCN?am?plified NB cells,knockdown of OLFM3 inhibited cells proliferation(P<0.001)and colony formation(P<0.001),but there was no noticeable changes observed in MYCN?non?amplified cells.Conclusions OLFM3 specifically pro?motes the proliferation of MYCN?amplified NB cells,but has a less effect on MYCN?non?amplified cells,indicating it is a potential biomarker for high?risk MYCN?amplified NB.

Objective To investigate the relationship between serum IL-8,homocysteine(Hey),C-reactive protein(CRP)levels and severity of coronary lesions in patients with coronary heart disease(CHD)complicated by chronic heart failure(CHF),as well as their prognostic value.Methods A total of 118 elderly eligible patients admitted to our hospital from January 2023 to September 2024 were prospectively recruited,and according to their Gensini score,they were divided into mild,moderate and severe stenosis groups(45,50 and 23 cases,respectively).Accord-ing to the clinical outcomes after follow-up,they were divided into a good prognosis group(82 cases)and a poor prognosis group(36 cases).The serum levels of IL-8,Hcy and CRP were com-pared among the three groups of different stenosis,and Pearson correlation analysis was used to examine the relationship between the three indicators and the severity of coronary lesions.Cox regression analysis was performed to identify factors influencing poor prognosis in patients with CHD and CHF,and receiver ROC curve analysis was conducted to assess the diagnostic value of serum IL-8,Hey,and CRP levels in predicting prognosis.Results The serum levels of IL-8,Hey and CRP were gradually decreased in the severe,moderate and mild stenosis groups in turn,with statistical significances(P＜0.05).Pearson correlation analysis indicated that serum IL-8,Hcy,and CRP levels were positively correlated with the severity of coronary lesions in the patients with CHD and CHF(r=0.364,0.355,0.372,P＜0.01).Significant differences were found in age,NT-proBNP,D-D,IL-8,Hcy,and CRP levels between the good and poor prognosis groups(P＜0.05).Cox regression analysis revealed that age,NT-proBNP,D-D,IL-8,Hcy,and CRP were influencing factors for poor prognosis in patients with CHD and CHF(P＜0.05).ROC curve ana-lysis showed that the AUC value of IL-8,Hey,CRP,and their combination in predicting prognosis was 0.698,0.714,0.723 and 0.899,respectively.Conclusion In the patients with CHD and CHF,serum IL-8,Hcy,and CRP levels are associated with the severity of coronary lesion and prognosis.Moreover,combining these three indicators has significant diagnostic value for predicting patient outcomes.

Objective To explore the effect of open reading frame 66(C12ORF66)located at chromosome 12 on the viability of MYCN amplified NB cell lines.Methods DDatasets GSE16476 and GSE49710 in R2 database were analyzed for expression level of C12ORF66 in MYCN amplified and MYCN non-amplified NB cells and its potential correlation with the prognosis of pediatric patients.C12ORF66 mRNA expression level in normal tissue immortalized cell lines,MYCN amplified and MYCN non-amplified cell lines were detected by RT-qRCR.Transient or stable knockdown of C12ORF66 cell lines were constructed to compare the difference in real time cellular analysis(RTCA),colony formation,Ki67 positive cells between the control group and the C12ORF66 knockdown group.Results By analyzing R2 datasets,C12ORF66 level in MYCN amplified samples was significantly higher than that in MYCN non-amplified samples,and the expression of C12ORF66 was negatively correlated with the prognosis of pediatric patients(P＜0.05).C12ORF66 highly expressed in MYCN-amplified BE(2)-C and SK-N-BE(2)cell lines than in MYCN non-amplified CHLA-255 and SH-SY5Y cell lines(P＜0.001).Transient or stable knockdown of C12ORF66 resulted in significant slow down of proliferation of MYCN amplified NB cells(P＜0.001),the colony formation ability was significantly reduced(P＜0.001),and the proportion of Ki67 positive cells was significantly decreased(P＜0.05).Conclusions C12ORF66 was highly expressed in MYCN amplified clinical NB samples and cell lines which is believed to be correlated with poor prognosis of pediatric patients.C12ORF66 knockdown signifi-cantly inhibits cell viability of NB cells.
