Background Baicalin has anti-infammatory, antibacterial, blood platelet aggregation-inhibiting, free oxygen radical-clearing, and endotoxin-decreasing properties. However, its molecular mechanism involved in the treatment of Adriamycin-induced nephrotic syndrome (NS) is still unclear. Objective This study aimed to explore the efects of baicalin on Adriamycin-induced nephrotic syndrome (NS) and to characterize the genes involved in this progression. Methods We established Adriamycin-induced NS model in 32 rats and used six rats in Sham group. Urinary total protein content and creatinine serum were assessed as physiological indicators. H&E staining was used to observe the pathological changes. We determined gene expression profles using transcriptome sequencing in the rat kidney tissues from Sham, Adriamycin, and Adriamycin+baicalin groups. KEGG was carried out to analyze the enriched pathways of diferentially expressed genes among these groups. Results Baicalin treatment relieved renal injury in NS rats. Expression of 363 genes was signifcantly diferent between the Adriamycin and Adriamycin+baicalin M groups. Most of the diferentially expressed genes were enriched in pathways involved in epithelial-mesenchymal transition (EMT), fbrosis, apoptosis, and infammation. Conclusions Overall, these data suggest that Adriamycin-induced NS can be attenuated by baicalin through the suppression of fbrosis-related genes and infammatory reactions. Baicalin is a potential drug candidate for the treatment of NS, and the identifed genes represent potential therapeutic targets.

The fallwebworm, Hyphantria cunea (Drury) (Lepidoptera: Arctiidae), is an invasive and important pest in China. Understanding the physiological–biochemical characteristics of the overwintering pupae is essential for its cold tolerance and potential distribution in the northeast of China. Results indicated that the supercooling point (SCP) of H. cunea overwintering pupae varied significantly among Jilin city (43°N, 126°E), Jilin Province, Shenyang (41.8°N, 123.4°E), Liaoning Province and Yingkou (40.39°N, 122.13°E), Liaoning Province. The average SCP in Jilin was the lowest (−23.49 ± 0.46 °C) in those of three areas. The water content in overwintering pupae had a significant positive correlation with the SCP (R = 0.848,P = 0.03). Contents of alanine (ALA) (26.00%), lysine (LYS) (30.51%) and arginine (ARG) (22.88%) in the overwintering pupae's hemolymph were higher than others. During the overwintering, the fat content in pupae's bodies decreased gradually. Analysis of variance (ANOVA) indicated that the content of trehalose in the body of H. cunea was remarkably different (P= 0.007) month by month, with the maximum in March (2.88 mg·mL−1) and the minimum (0.40 mg·mL−1) in November. Pearson's correlation test indicated that SCP had a significant negative correlation with the SOD enzyme activity (R = −0.850; P = 0.008). Thermal hysteresis activity (THA) of hemolymph was 0.68°C and 0.7–0.8°C for H. cunea pupae and larva, respectively, using differential scanning calorimetry, which suggests that the H. cunea can improve their cold tolerance through producing antifreeze proteins. These results could help us to predict the distribution of the H. cunea in the northeast of China.
