Objective To investigate the therapeutic effect of Huangkui capsules on targeted drug-related proteinuria in patients with hepatocellular carcinoma (HCC). Methods A retrospective analysis was conducted on clinical data of HCC patients with targeted drug-related proteinuria from June 2023 to December 2024 at Zhongshan Hospital, Fudan University. According to the treatment plan, patients were divided into the conventional treatment group and the Huangkui combination treatment group (Huangkui capsules combined with conventional treatment), and the clinical efficacy between the two groups was compared. The logistic regression analysis was used to identify the main factors affecting treatment efficacy. Results The Huangkui combination treatment group (n＝29) showed a significantly higher overall effective rate (79.3% vs 42.3%, P＝0.005), and an earlier proteinuria improvement (median time: 3 months vs 6 months, P＝0.008) than the conventional treatment group (n＝26) . The multivariate logistic regression analysis showed angiotensin-converting enzyme inhibitor (ACEI) or angiotensin Ⅱ receptor blocker (ARB) using (OR＝0.190, 95%CI 0.045-0.808, P＝0.025), targeted drug adjustment (OR＝0.132, 95%CI 0.030-0.581, P＝0.007), and Huangkui capsules using (OR＝0.168, 95%CI 0.039-0.730, P＝0.017) were protective factors for treatment efficacy of targeted drug-related proteinuria. Conclusions On the basis of conventional treatment, additive treatment with Huangkui capsules can alleviate targeted drug-related proteinuria faster and more effectively in HCC patients.

Objective To investigate the effect of Nde1 gene knockout on early neural development of zebrafish by visualizing the development of neural networks in zebrafish.Methods Transgenic zebrafish Tg(Nde1-/-;HuC:RFP+/-)was constructed by crossing Nde1-/-with Tg(HuC:RFP+/-).The HuC promoter was employed to drive the expression of red fluorescent protein in neurons,which allowing the visualization of zebrafish neural networks and tracking of neural development.Furthermore,by using Image J and Prism to compare the average fluorescence intensity of neurons and the expression level of fluorescent reporter proteins between Nde1 deficiency zebrafish and wild type zebrafish,the effect of Nde1 gene knockout on zebrafish neural development was analyzed.Results From 48 hours post-fertilization(hpf)to 7 days dpf,the average fluorescence intensity of red fluorescence expressed by trigeminal sensory neurons and spinal cord neurons in Nde1 deficiency zebrafish was lower than that in wild type zebrafish.RT-qPCR results also showed that the mRNA expression level of red fluorescent reporter protein in Nde1 deficiency zebrafish was significantly lower than that in the wild type zebrafish.Conclusion Nde1 gene deletion may lead to abnormal development of trigeminal sensory neurons and spinal cordneurons by affecting neural progenitor cell differentiation and increasing apoptosis.

A recombinant adenovirus(rAd)for expression of Mycobacterium tuberculosis(M.tb)c-di-AMP phosphodiesterase CnpB was constructed,and its induced humoral immune response was detected.The codon-optimized gene of M.tb CnpB was cloned into the adenoviral plasmid pcADV.The recombinant plasmid pcADV-CnpB was transfected into HEK293T cells,and expression was detected with Western blot.The recombinant plasmid pcADV-CnpB and the backbone plasmid were co-transfected into HEK293T cells to obtain the recombinant adenovirus rAd-CnpB.rAd-CnpB was amplified in HEK293T cells,and the target protein expression of rAd-CnpB was detected with Western blot and immunofluorescence.Mice were immunized with rAd-CnpB intranasally,and their sera and bronchoalveolar lavage fluid(BALF)were collected.ELISA was used to detect levels of antigen-specific antibodies.Restriction enzyme digestion and sequencing indicated that the recombinant plasmid pcADV-CnpB was successfully constructed and led to protein expression in eukaryotic cells.rAd-CnpB was packaged and produced in HEK293T cells.After amplification and purification,rAd-CnpB with a titer of 5.53×1010 PFU/mL was obtained.rAd-CnpB led to CnpB expression in HEK293T cells.Intranasal immunization with rAd-CnpB increased levels of IgG and secretory IgA in BALF and led to high levels of IgG in sera.rAd-CnpB,the recombinant adenovirus for expression of c-di-AMP phosphodiesterase CnpB was successfully constructed,and was found to induce antigen-specific humoral and mucosal immune responses through mucosal immunization.Thus,rAd-CnpB may be used in further research on new TB vaccine strategies.

This study assessed the role and mechanism of the recombinant Bacillus Calmette-Gue?rin vaccine(rBCG)with c-di-AMP adjuvant in regulating metabolism and immunity in epididymal white adipose(eWAT)in mice.Male C57BL/6 mice were intravenously immunized with BCG and rBCG,and their body weights were monitored.eWAT was isolated from the mice,and the stromal vascular fractions(SVFs)cell number was counted with a hemocytometer.Sections of mouse adipose tissue were prepared,and the size,number,and morphology of eWAT adipocytes and crown-like structure(CLS)formation were compared under a microscope after HE staining.The transcription levels of lipid metabolism-associated factors,cytokines and aging-associated genes in each group were determined with qRT-PCR.The body weights of mice gradually increased after immunization with BCG and rBCG.The proportions of eWAT increased,and the SVFs cell number decreased,in rBCG immunized mice.HE staining indicated that BCG immunization promoted hyperplasia,whereas rBCG immunization promoted hypertrophy of eWAT adipocytes;moreover,both BCG and rBCG immunization induced CLS formation in eWAT.The qRT-PCR results indicated that rBCG immunization inhibited the expression of genes associated with lipolysis and energy expenditure in eWAT.BCG immunization had little effect on cytokine transcription,whereas rBCG significantly induced the transcription of IFN-γ and IL-1Ra,and inhibited that of IL-15 and IL-2,but did not induce the expression of aging-associated genes.Thus,rBCG immunization induced eWAT adipocyte hypertrophy,which was associated with the inhibition of eWAT lipolysis and the regulation of cytokine expression.

Objective To explore the correlation between the systemic immune-inflammation index(SII)and the clinical and pathological characteristics of patients with IgA nephropathy(IgAN).Methods A total of 350 patients who underwent renal biopsy and were initially diagnosed with primary IgAN were selected.The clinical and pathological data of the patients were collected,and SII was calculated.According to the median SII level of 554.78 in peripheral blood,the IgAN patients were divided into the low SII group(SII≤554.78,175 cases)and the high SII group(SII>554.78,175 cases).Based on the presence or absence of endocapillary hyperplastic(E)lesion,350 patients were also divided into the E0 group(279 cases,79.7%)and the E1 group(71 cases,20.3%).Multivariate Logistic regression analysis was conducted to determine the influencing factors of E1 in IgAN patients.A predictive model was established,and the predictive value of the model was evaluated using the receiver operating characteristic(ROC)curve.Results There were higher systolic blood pressure(SBP),platelet count(PLT),neutrophil count(NEU),neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),total cholesterol(TC),serum creatinine(Scr),serum C3 and 24-hour urine protein levels in the high SII group than those of the low SII group,while the lymphocyte count(LYM)was lower(P＜0.05).In terms of pathological manifestations,the proportion of E1 was higher in the high SII group than that of the low SII group(P＜0.05).There were lower PLT,NEU,NLR,PLR,Scr and 24-hour urine protein in patients of the E0 group than those of the E1 group,while higher Hb,LYM and ALB levels in the E0 group than those of the E1 group(P＜0.05).Multivariate Logistic regression analysis showed that elevated SII,Scr and 24-hour urine protein levels were independent risk factors for E1 lesion in IgAN patients(P＜0.05).The area under the curve(AUC)of the predictive model for E1 lesion in IgAN patients was 0.781(95%CI:0.722-0.840).Conclusion SII can reflect the clinical and pathological severity in IgAN patients,providing new insights for clinical evaluation of the disease progression in IgAN patients.
