Effect of multi-glycosides of Tripterygium wilfordii on renal injury in diabetic kidney disease rats through NLRP3/caspase-1/GSDMD pyroptosis pathway / 中国中药杂志

This study investigated the effect of multi-glycosides of Tripterygium wilfordii(GTW) on renal injury in diabetic kidney disease(DKD) rats through Nod-like receptor protein 3(NLRP3)/cysteine-aspartic acid protease-1(caspase-1)/gsdermin D(GSDMD) pyroptosis pathway and the mechanism. To be specific, a total of 40 male SD rats were randomized into the normal group(n=8) and modeling group(n=34). In the modeling group, a high-sugar and high-fat diet and one-time intraperitoneal injection of streptozotocin(STZ) were used to induce DKD in rats. After successful modeling, they were randomly classified into model group, valsartan(Diovan) group, and GTW group. Normal group and model group were given normal saline, and the valsartan group and GTW group received(ig) valsartan and GTW, respectively, for 6 weeks. Blood urea nitrogen(BUN), serum creatinine(Scr), alanine ami-notransferase(ALT), albumin(ALB), and 24 hours urinary total protein(24 h-UTP) were determined by biochemical tests. The pathological changes of renal tissue were observed based on hematoxylin and eosin(HE) staining. Serum levels of interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected by enzyme-linked immunosorbent assay(ELISA). Western blot was used to detect the expression of pyroptosis pathway-related proteins in renal tissue, and RT-PCR to determine the expression of pyroptosis pathway-related genes in renal tissue. Compared with the normal group, the model group showed high levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), low level of ALB(P<0.01), severe pathological damage to kidney, and high protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01). Compared with the model group, valsartan group and GTW group had low levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), high level of ALB(P<0.01), alleviation of the pathological damage to the kidney, and low protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01 or P<0.05). GTW may inhibit pyroptosis by decreasing the expression of NLRP3/caspase-1/GSDMD in renal tissue, thereby relieving the inflammatory response of DKD rats and the pathological injury of kidney.

Sequential Treatment with Syndrome Differentiation on Children's Refractory Nephrotic Syndrome with Yiqi Huayu Qingre Prescription / 中国实验方剂学杂志

ObjectiveTo evaluate the clinical efficacy of sequential syndrome differentiation of Yiqi Huayu Qingre prescription （YHQ） in the treatment of refractory nephrotic syndrome in children. MethodA total of 112 children with refractory nephrotic syndrome were randomly divided into an observation group （57 cases） and a control group（55 cases）. The children in the control group were treated with prednisone tablets combined with tacrolimus，and those in the observation group were treated with YHQ by sequential syndrome differentiation on the basis of the control group. The total effective rates of the two groups after treatment were observed. The 24-hour urinary total protein（24 h UTP），plasma albumin（ALB），cholesterol（CHO），triglycerides（TG）， and traditional Chinese medicine quality of life scale scores before treatment and after four weeks，eight weeks，16 weeks，24 weeks，32 weeks，40 weeks，and 52 weeks in the two groups were recorded. The total course of treatment and the total accumulation of hormones were compared among the children with reduced or no hormone treatment till 52 weeks during treatment. ResultThe total effective rate in the observation group was higher （Z=-2.052，P<0.05）. The observation group had lower 24 h UTP and higher ALB at each follow-up time point than the control group（P<0.05，P<0.01）. At four weeks，eight weeks，and 16 weeks of treatment，there was no statistically significant difference in CHO between the observation group and the control group，and the observation group was lower than the control group in CHO at the rest of the time points （P<0.05，P<0.01）. For TG， the observation group was not significantly different from the control group at four weeks，eight weeks，16 weeks，and 40 weeks of treatment，but lower at 24，32，and 52 weeks （P<0.05，P<0.01）. The total treatment course of hormones in the observation group was shorter（P<0.01）， with less total accumulation（P<0.01）. At different follow-up time points，the total score of traditional Chinese medicine quality of life scale in the observation group was superior to that in the control group（P<0.05，P<0.01），and the scores of the observation group in the four dimensions （physiological function，independent factor，social factor，and psychological factor） after treatment were higher than those in the control group（P<0.05，P<0.01）. ConclusionYHQ under sequential syndrome differentiation has a definite clinical effect in treating children with refractory nephrotic syndrome. It has advantages in shortening the total course of hormone treatment and reducing the total accumulation of hormones，and can improve the quality of life of children with refractory nephrotic syndrome.

Study on mechanism of Cuscutae Semen flavonoids in improving reproductive damage of Tripterygium Glycosides Tablets in rats based on high-throughput transcriptome sequencing / 中国中药杂志

Tripterygium Glycosides Tablets has good anti-inflammatory and immunomodulatory activities,but its reproductive damage is significant. Previous studies of the research group have found that Cuscutae Semen flavonoids can improve spermatogenic cell damage caused by Tripterygium Glycosides Tablets by regulating spermatogenic cell cycle,apoptosis and related protein expression,but the mechanism of action at the gene level is still unclear. In this study,Illumina high-throughput sequencing platform was applied in transcriptional sequencing of spermatogenic cells of rats after the intervention of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets. Differentially expressed genes were screened out and the GO enrichment and KEGG pathway analysis of differentially expressed genes were conducted to explore the mechanism of Cuscutae Semen flavonoids in improving reproductive injury caused by Tripterygium Glycosides Tablets. The results showed that 794 up-regulated genes and 491 down-regulated genes were screened in Tripterygium Glycosides Tablets group compared with the blank group. Compared with Tripterygium Glycosides Tablets,440 up-regulated genes and 784 down-regulated genes were screened in the Cuscutae Semen flavonoids+Tripterygium Glycosides Tablets group. Among them,the gene closely related to reproductive function is DNMT3 L. Analysis of GO function and KEGG signaling pathway enrichment showed that the above differentially expressed genes were mainly enriched in cell,cell process,catalytic activity,binding,ovarian steroid synthesis,thyroid hormone and other functions and pathways. The thyroid hormone signaling pathway was the common enrichment pathway of the two control groups. In a word,Cuscutae Semen flavonoids has a good treatment effect on male reproductive damage caused by Tripterygium Glycosides Tablets. The mechanism may be closely related to up-regulation of DNMT3 L genes and intervention of thyroid hormone signaling pathway. At the same time,the discovery of many different genes provides valuable information for study on the mechanism of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets compatibility decreasing toxicity and increasing efficiency.

Long-term effect of Tripterygium Glycosides Tablets combined with traditional Chinese medicine on adulthood fertility / 中国中药杂志

To preliminarily investigate the effect of Tripterygium Glycosides Tablets( TGT) combined with traditional Chinese medicine( TCM) on the fertility and female menstruation on persons who have took during childhood. The children with henoch-schonlein purpura( HSP) or henoch-schonlein purpura nephritis( HSPN) who treated with TGT under 18 years old and now older than 18 years old( including 18 years old) during January 1998 to December 2010 were selected in our research. The content of follow-up visit included marriage,marriage age,fertility and child health; and unmarried female patients were asked whether they had menstrual abnormalities. The data of the unmarried female patients,including age,clinical classification,TCM syndrome type,initial dose and other related factors that may affect menstrual cycle,was analyzed by using binary logistic regression analysis. A total of 195 patients who met the criteria were followed up in this study,and 26 patients married for more than 1 year. Among the 26 married patients,1 HSP patient had no birth planning due to rheumatoid arthritis,and the remaining 25 patients all had given birth or were pregnant. The 169 unmarried patients included 89 female patients. Among the 89 female patients,4 cases refused to tell the menstrual situations,72 cases had normal menstruation( 84. 7%),13 cases had abnormal menstruation( 15. 3%),and there was no case of amenorrhea. Logistic regression analysis results showed that the age,clinical classification,TCM syndrome type and initial dose had no correlation with abnormal menstruation. Our results demonstrated that TGT has no effect on adulthood fertility among patients who took TGT combined with traditional Chinese medicine during childhood.
