In addition, Fructus Arctii has been used in clinical therapy for diabetic nephropathy. On the basis of the TCM theory of heat in diabetes mellitus and the clinical efficacy of Fructus Arctii, the two compounds were used to develop a formula named Compound Herba Houttuyniae. This study evaluated the renoprotective effects of different Compound Herba Houttuyniae extracts and assessed their mechanisms through the Janus kinase/signal transducer and activator of transcription（JAK/STAT）–suppressors of cytokine signaling（SOCS）-1 pathway. Methods The normal group comprised db/m mice（n = 8）; db/db mice were randomly divided into six groups according to the applied treatment method： model group（no treatment）, AG490 group, petroleum ether extract（PEE） group, ethyl acetate extract（EAE） group, N-butanol extract（NE） group, and water extract（WE） group（n = 6 in each group）. The general status, biochemical indicators, and renal histological changes in the mice were evaluated, and the JAK/STAT–SOCS-1 pathway was assessed. Results The NE and WE groups showed a decrease in 24-h urinary protein and albumin levels as well as serum uric acid and fibronectin levels but showed no changes in fasting plasma glucose and hemoglobin A1 c levels. The protein expression of JAK2, STAT3, P-JAK2, and P-STAT3 and the gene expression of JAK2 and STAT3 in kidney tissues were significantly increased（P 〈 0.05） in the model group. Compared with the model group, the expression of P-JAK2 and P-STAT3 was downregulated in the extract treatment groups. The expression of SOCS-1 was increased in the NE and WE groups（P 〈 0.05）. However, the expression of JAK2, STAT3, JAK2 m RNA, and STAT3 m RNA in the treatment groups did not show any significant differences. Conclusion Compound Herba Houttuyniae showed renoprotective effects in db/db mice, and the strongest effects were observed in the WE and NE groups. The underlying mechanism for these effects might involve the regulation of the JAK/STAT–SOCS-1 pathway.展开更多

After 8 weeks,the general status, biochemical indicators, and renal histological changes in the mice were evaluated,the total RNA and protein were collected and RT-PCR method was used to examine the effect on mRNA expression of JAK2, STAT3, SOCS1, and Western blot method was used to detect the protein expression of JAK2, P-JAK2, STAT3, P-STAT3, SOCS1, c-fos, and c-jun. Immunofluorescence was used to observe the protein expression of c-fos and c-jun in kidney tissue.Results： Compared with normal group, the serum level of TGF-β1, FN of EE, VO, and MG groups were decreased（P 〈 0.05）. Renal function was also improved but not significantly. Also, the renal histology was improved especially in the mixture group. The protein expression of JAK2, STAT3, P-JAK2, P-STAT3, and the genetic expression of JAK2 and STAT3 in kidney tissue were significantly increased in the model group（P 〈 0.05）. Compared with the model group, the expression of P-JAK2 and P-STAT3 was down-regulated in treatment groups; The expression of SOCS-1 of VO and mixture groups were elevated（P 〈 0.05）.Conclusion： CHH has beneficial effects on diabetic renal injury, which may protect and improve the kidney function and reduce urinary protein, maintain the integrity of the kidney structure and function.展开更多

In this study, orthogonal experimental design was used to investigate the influencing factors on the pH stability of Yuxingcao injection. Two methods of accelerated tests were carried out in the experiments. The results showed that using Tween 80 as the solubilizer could significantly decrease the pH value of Yuxingcao injection after accelerated tests. There was no significant difference in the pH value after the accelerated tests when the other 6 factors varied, including the type of liquid processed, the dosage of activated carbon, heating temperature, reagents for pH adjustment, pH value range after adjustment, and sterilization conditions. In order to improve the quality stability of Yuxingcao injection, the quality of Tween 80 should be strictly controlled to minimize the change of pH value of Yuxingcao injection.展开更多
