Objective To identify potential biomarkers associated with LN,with the goal of improving early diagnosis,disease monitoring,and the development of more precise treatment strategies.Methods Gene expression data were downloaded from the Gene Expression Omnibus(GEO)database for datasets GSE22221,GSE112943,GSE99967,and GSE32591.Intersecting genes were obtained through the application of weighted gene co-expression network analysis(WGCNA)and linear models for microarray data(LIMMA).Subsequently,biological function and pathway analyses were conducted on these intersecting genes using Gene Ontology(GO)and the Kyoto Encyclopedia of Genes and Genomes(KEGG).Next,protein-protein interaction(PPI)network analysis was performed,and hub genes highly associated with LN were identified using the CytoHubba algorithm,support vector machine(SVM),and random forest(RF)methods.Receiver operating characteristic(ROC)analysis was performed,and three potential biomarkers were validated using the GSE72798 dataset.Results The green-yellow module(P=7.4e-40)and the cyan module(P=1.5e-14)were identified through WGCNA analysis.A total of 193 differentially expressed genes were identified using LIMMA,with 113 intersecting genes related to LN being identified.GO and KEGG analyses indicated that these genes were mainly enriched in viral or bacterial defense,type I interferon signaling pathway,neutrophil-mediated immunity,and Toll-like receptor signaling.MX1,IFI44,and STAT1 were identified as hub genes using CytoHubba,SVM,and RF methods,with AUC values of 0.874,0.879,and 0.833,respectively.Validation using the GSE72798 dataset demonstrated that the expression of MX1,IFI44,and STAT1 was significantly higher in LN patients compared to healthy individuals(P＜0.001 for all).Conclusion MX1,IFI44,and STAT1 play crucial roles in the pathogenesis of LN and may serve as important biomarkers and potential therapeutic targets for LN.

Objective To evaluae the meaning and value of ultrasonography in the diagnosis of cubital tunnel syndrome(CuTS).Methods Forty patients(unilateral) of cubital tunnel syndrome(contralateral control group)were used to measure the ulnar nerve entrapment and the most extensive cross-sectional area and circumference.All cases underwent cubital incision preoperative,intraoperative direct vision under surgical line wrapped around the ulnar nerve compression and the most rough after a lap cut,and then we measured with a ruler,the two measurement methods comparison.The diagnostic threshold and the sensitivity and specificity of the most extensive cross -sectional area of the ulnar nerve and perimeter was analysed by using the receiver operating characteristic (ROC) curve.Results The most extensive cross-sectional area and circumference of the ulnar nerve in the CuTS group were significantly higher than those in the control group,and the difference was statistically significant.Forthe ultrasound measurement and intraoperative measurement of CuTS group at the pressure and the most rough circumference,the difference was not statistically significant,indicating that ultrasound can accurately measure the ulnar nerve circumference.The optimal cut-off point of the most rough cross-sectional area of the ulnar nerve and the circumference of the CuTS group were respectively 14.2mm2 and 14.8mm,and sensitivity were respectively 92.5％ and 90％,the specificity were respectively 97.5％ and 87.5％.Conclusion Ultrasonography is a new and valuable method for the diagnosis of cubital tuunel syndrome by measuring cross-sectional area and circumference of elbow.The optimal cut-off point of the most rough cross-sectional area of the ulnar nerve and the circumference of the CuTS group were respectively 14.2mm2 and 14.8mm.

Objective To study the prognostic role of plasma neutrophil gelatinase-associated lipocalin (NGAL) early after renal transplantation.Methods A total of 37 kidney recipients were enrolled from Department of Organ Transplantation,Guangdong Second Provincial General Hospital within a 12-month period of time.Plasma NGAL was measured immediately before and at 6 and 12 h post-transplantation.Changes of serum creatinine were documented daily within the first week postoperation.Acute kidney injury (AKI)/graft rejection during the first week after transplantation was the outcome variable.Results The levels of serum NGAL in the 37 patients were (311.14 ± 102.69),(317.81 ± 107.28) and (312.16 ± 134.80) μg/L respectively immediately before and at 6 and 12 h post-transplantation.There was no significant difference in serum NGAL levels before and 6 h or 12 h after operation (P =0.70,and P =0.96).There were no significant differences in gender and age between the two groups (P =0.29,and P =0.20).There was significant difference in creatinine levels between the AKI group and the non-AKI group (P =0.002) and between pre-operation and 6 or 12 h postoperation.The preoperative levels of serum NGAL in AKI group and non-AKI group were (333.58 ± 116.30) and (300.36 ± 96.15) μg/L (P =0.36),and those were (383.3 ± 147.16) and (286.32 ± 65.97) μg/L (P＜0.01) at 6 h,and (437.33 ± 164.16) and (252.08 ± 57.53) μg/L (P＜ 0.001) at 12 h after operation.The sensitivity and specificity of serumNGAL (317μg/L at 12 h after operation as the cutoff value) predicting AKI was 100％ and 92％ respectively,which was much better than that of serum creatinine at the corresponding time point (sensitivity =66.7％,and specificity =61.9％).Conclusion Plasma NGAL,particularly at 12 h after transplantation,is a very sensitive and specific biomarker for predicting AKI.
