Objective:Using bioinformatics methods to study the immune infiltration mechanism of lupus nephritis(LN)and to explore potential target Chinese medicines,which can provide new directions for clinical treatment of LN.Methods:Gene expres-sion profile microarray dataset of LN was downloaded from GEO database,differential expressed genes(DEGs)were screened using R software,and GO and KEGG enrichment analysis were performed on these DEGs.Protein interaction network analysis of DEGs was performed by applying STRING database,key genes were screened by using Cytoscape,core gene expression was validated by Nephro-seq database,and the infiltration and correlation of 22 kinds of immune cells in LN were calculated by CIBERSORT deconvolution algorithm.Finally,herbal prediction of significantly enriched immune-related biological processes and key target genes were performed by Coremine Medical database.Results:A total of 367 LN-related DEGs were obtained,of which 253 were up-regulated and 114 were down-regulated.GO was mainly enriched in response to viruses,defense response to viruses,regulation of viral life cycle,regulation of viral processes,etc;KEGG was mainly enriched in S.aureus infection,COVID-19,influenza A,complement and coagulation cascade,pertussis,etc.Ten key genes were screened:IFIT3,OAS2,MX1,OAS1,RSAD2,XAF1,ISG15,IFIT1,ITGAM and PTPRC.Immune infiltration by CIBERSORT deconvolution algorithm showed that monocytes and initial B cells were highly expressed in LN,while memory B cells,naive CD4+T cells,follicular helper T cells and resting natural killer cells were lowly expressed in LN.Immune cell correlation analysis showed a positive correlation between initial B cells and plasma cells,a positive correlation between resting natural killer cells and resting dendritic cells,a negative correlation between monocytes and regulatory T cells,and a negative correlation between resting CD4+memory T cells and monocytes.Coremine Medical predicted that Salvia miltiorrhiza,Panax notogin-seng,Scutellaria baicalensis,ginseng,honey,monkey mushroom and peony were found to be most closely related to immunity in LN.Conclusion:The development and progression of LN are results of the combined involvement of multiple genes and pathways.Mono-cytes,memory B cells,initial CD4+T cells and initial B cells are most closely associated with LN.The predicted Salvia miltiorrhiza,Panax notoginseng,Scutellaria baicalensis,ginseng,honey,monkey mushroom and peony may be used as target herbs for the poten-tial treatment of LN.

Objective:To investigate the dynamic trend of platelet（PLT）count and mean platelet volume（MPV）in children with severe community-acquired pneumonia（SCAP）in PICU and their correlation with prognosis.Methods:A retrospective study was conducted in 215 SCAP children who were admitted to the PICU of Beijing Children's Hospital Affiliated to Capital Medical University from January 2016 to December 2019.According to the disease outcome，the patients were divided into improvement group ( n=184) and unrecovered group ( n=31).The changes of PLT count and MPV at admission，on the 2nd，3rd，and 7th days of hospitalization and before discharge were observed，and the relationship between changes in PLT parameters and poor prognosis was analyzed. Meanwhile，the correlation between thrombocytopenia on admission and on the 7th day of hospitalization and prognosis was further explored. Results:The PLT count of improvement group at admission，on the 2nd，3rd，and 7th days of hospitalization and at discharge[(328±159, 329±137, 362±159, 439±168, 510±171)×10 9/L] were significantly higher than those of unrecovered group [(210±142, 207±152, 267±143, 260±162, 343±159)×10 9/L]（ P＜0.05）.Although the MPV of improvement group [(10.9±1.9)fL] on admission was significantly lower than that of the unrecovered group[(12.7±2.5) fL]（ P＜0.05），there was no significant difference in MPV between two groups on the 2nd，3rd，7th days of hospitalization and discharge（ P＞0.05）.In addition，compared with the admission，children in improvement group had significantly higher PLT count on the 7th day of hospitalization and before discharge（ P＜0.05），but there was no significant change in unrecovered group（ P＞0.05）.Compared with SCAP patients with thrombocytopenia at admission (PLT＜100×10 9/L)( n=22),those with thrombocytopenia on 7th day of hospitalization had a significant higher rate of non recovery( P＜0.05). Conclusion:The occurrence of thrombocytopenia on admission and after 7 days of hospitalization in children with SCAP is associated with poor prognosis.No significant increase or decrease in PLT count after 7 days of hospitalization is often indicative of poor prognosis.Dynamic monitoring of PLT parameter changes may help to better judge the prognosis of severe pneumonia.

Objective:To compare the diagnostic efficacy of 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT, 18F-FDG PET/CT and multi-parameter MRI (mpMRI) in prostate cancer (PCa). Methods:Retrospective analysis was conducted on data from 22 patients ((72.6±6.2) years) with pathologically confirmed PCa in the Affiliated Taizhou People′s Hospital of Nanjing Medical University between April 2021 and September 2022. All patients underwent 18F-PSMA-1007 PET/CT, 18F-FDG PET/CT, and mpMRI examination within 30 d, and the imaging parameters were collected, including PSMA-SUV max, FDG-SUV max, minimum apparent diffusion coefficient (ADC min), mean apparent diffusion coefficient (ADC mean), PSMA-SUV max/ADC min, PSMA-SUV max/ADC mean, FDG-SUV max/ADC min, FDG-SUV max/ADC mean. Patients were divided into groups based on the International Society of Urological Pathology (ISUP) grading (≤3 vs >3) and serum total prostate specific antigen (TPSA; ≤20 μg/L vs >20 μg/L), and differences of imaging parameters between groups were compared (Mann-Whitney U test or independent-sample t test). ROC curves were generated to evaluate the diagnostic ability of each parameter for different levels of PCa. χ2 test and ROC curve analysis were used to compare the detection rate and diagnostic efficiency of three imaging methods for primary focus, lymph node metastasis, and bone metastasis in PCa. Results:Differences were found between ISUP≤3 ( n=6) and >3 ( n=16) groups in PSMA-SUV max/ADC min, PSMA-SUV max/ADC mean, PSMA-SUV max, and ADC min ( z values: from -2.65 to -2.36, t=3.60, P values: 0.002-0.018). But there was no significant difference found between TPSA≤20 μg/L ( n=5) and >20 μg/L ( n=17) groups in all indices ( z values: from -1.76 to -1.45, t values: -1.19 and 1.28, all P>0.05). The optimal cut-off value for PSMA-SUV max/ADC min in differentiating high-grade and low-grade PCa was determined to be 22.628×10 3. In the patient-based analysis, no statistical difference was found in the detection rate of PCa primary tumors among 18F-PSMA-1007 PET/CT, 18F-FDG PET/CT, and mpMRI ( χ2=1.91, P=0.767). However, the detection rates of lymph node and bone metastasis among three imaging methods were significantly different (72.73%(16/22), 59.09%(13/22), 36.36%(8/22) and 81.82%(18/22), 63.64%(14/22), 45.45%(10/22); χ2 values: 6.03, 6.29; P values: 0.049, 0.043). 18F-PSMA-1007 PET/CT resulted in a 36.36%(8/22) increase in N stage and the 40.91%(9/22) increase in M stage compared to mpMRI. Conclusions:PSMA-SUV max/ADC min is a valuable parameter for differentiating high-grade and low-grade PCa. 18F-PSMA-1007 PET/CT demonstrates superior detection rate of PCa lymph node and bone metastasis compared to 18F-FDG PET/CT and mpMRI, and exhibits higher diagnostic efficiency, so it can be recommended for NM staging in patients with PCa.
