Objective To analyze the clinical value of ultrasound-guided percutaneous renal biopsy for pathological diagnosis of diffuse renal disease. Methods Retrospective analysis of 275 patients with diffuse renal disease in our hospital underwent ultrasound-guided percutaneous renal biopsy for diagnosis. According to the above-mentioned patients' biopsy status,puncture satisfaction,success rate of material extraction,complications,and diffuse results of pathological typing of nephropathy and correction of postoperative diagnosis were analyzed. Results The satisfaction rate of puncture,the success rate of material extraction and the total incidence of complications were 94%,100%,and 10.91%,respectively. The incidence of postoperative complications in 275 patients was related to age,number of punctures,thickness of renal parenchyma,and preoperative serum creatinine levels. Membrane nephropathy and IgA nephropathy were the most common in 275 patients,accounting for 23.27% and 18.55% respectively. The correction rate of postoperative diagnosis in 275 patients was 19.79%. Conclusion Ultrasound-guided percutaneous renal biopsy is a safe and effective method for diagnosing diffuse nephropathy,and the incidence of postoperative complications is low and mild. Membrane nephropathy and IgA nephropathy have a higher incidence in the diagnosis of diffuse nephropathy. Ultrasound-guided percutaneous renal biopsy may early diagnose the pathological type of diffuse renal disease,provide a reliable basis for determining the treatment plan,and improve the prognosis of renal disease.

Objective To analyze the clinical significance of blue laser imaging (BLI)technology combined with Fuji intelligent chromo endoscopy (FICE)in the diagnosis of early esophageal cancer. Methods 108 cases of patients with esophageal suspicious lesions admitted to our hospital from January 2016 to June 2018 were enrolled in the study. They were given different modes of white light, FICE and BLI for observation and diagnosis, and the magnifying endoscopy model was combined to observe the intraepithelial papillary capillary loop (IPCL)at lesions sites for IPCL typing. After complete endoscopic examinations, the lesions were taken for pathological examination. The accuracy, sensitivity, specificity, positive predictive value, negative predictive value and Kappa value of each method were tested by Kappa consistency test. Spearman correlation analysis was used to analyze the correlation between IPCL classification and pathological diagnosis under each method. Results Kappa consistency test showed that the accuracy, sensitivity, specificity, positive predictive value, negative predictive value and Kappa value of white light endoscopy, FICE, BLI and FICE+BLI were increased in the diagnosis of early esophageal cancer. IPCL classification under combined magnifying endoscopy showed that type IV was mainly early esophageal cancer, and types I-III were mainly precancerous lesions. Spearman correlation analysis showed that through FICE, BLI and BLI combined with FICE for diagnosis, IPCL classification was positively correlated with early esophageal cancer, and the correlation of BLI combined with FICE was stronger than that of BLI or FICE. Conclusions BLI combined with FICE can greatly improve the diagnosis rate of early esophageal cancer. Combined with magnifying endoscopy, IPCL classification can judge the pathological types of early esophageal cancer.
