RESUMEN
ObjectiveTo explore the molecular mechanism of Qidi Tangshen prescription （QDTS） in regulating podocyte pyroptosis in diabetes nephropathy （DN）. MethodThrough in vivo experiment， db/db mice were divided into the model group， QDTS group （3.34 g·kg-1）， valsartan capsule group （10.29 mg·kg-1）， with db/m mice serving as the normal control. Each group consisted of 8 mice， and they underwent continuous intervention for 8 weeks. After the last administration， mice were euthanized， and kidney pathological changes were observed. Additionally， the expression levels of pyroptosis-related indicators， including NOD-like receptor protein 3 （NLRP3）， Gasdermin D protein （GSDMD）， and interleukin-1β （IL-1β） protein， were examined. Through in vitro experiment， mouse podocytes were divided into the normal glucose group （5.5 mmol·L-1 glucose）， high glucose group （35 mmol·L-1 glucose）， DMSO group （35 mmol·L-1 glucose+200 mg·L-1 DMSO）， and QDTS group （35 mmol·L-1 glucose+200 mg·L-1 QDTS freeze-dried powder）. After 48 hours of intervention， the expression levels of NLRP3， GSDMD， and IL-1β proteins were measured in podocytes. A drug-ingredient-target-disease interaction network for QDTS in the treatment of DN was constructed by network pharmacology methods. The key signaling pathways regulating podocyte pyroptosis were analyzed， and validation was conducted through in vivo and in vitro experiments. ResultCompared with normal group， glomerular hyperplasia and glomerular basement membrane thickening were observed in model group， and some segments were accompanied by obvious podocellular process fusion. The protein expressions of NLRP3， GSDMD and IL-1β in mouse kidney were increased， the protein expressions of mitogen-activated protein kinase 14 （MAPK14）， V-Rel reticuloendotheliosis virus oncogene homology A （RELA） and Caspase-8 in mouse kidney were increased （P<0.05）. Compared with model group， kidney pathological injury of mice in QDTS group was significantly reduced， and the expressions of NLRP3， GSDMD and IL-1β in kidney of mice in QDTS group and valsartan group were decreased （P<0.05）. The protein expressions of MAPK14， RELA and Caspase-8 in kidney of mice in QDTS group and valsartan group were decreased （P<0.05）. Network pharmacology results showed that there were 16 targets for QDTS to regulate DN cell pyrodeath， among which MAPK14， RELA and Caspase-8 were the key targets. Compared with normal glucose group， the protein expressions of NLRP3， GSDMD and IL-1β in high glucose group were increased （P<0.05）， and the protein expressions of MAPK14， RELA and Caspase-8 in mouse podocytes were increased （P<0.05）. Compared with high glucose group， the expressions of NLRP3， GSDMD and IL-1β in podocytes of mice in QDTS group were decreased （P<0.05）， and the expressions of MAPK14， RELA and Caspase-8 in podocytes of mice in QDTS group were decreased （P<0.05）. ConclusionQDTS reduces damage to DN podocytes， which is associated with its regulation of the MAPK14/RELA/Caspase-8 signaling pathway and inhibition of podocyte pyroptosis.
RESUMEN
ObjectiveTo explore the mechanism of Qidi Tangshen prescription （QDTS） in alleviating podocyte injury and reducing urinary protein in diabetic nephropathy （DN）. MethodUsing network pharmacology methods， we collected the chemical components and targets of QDTS， as well as the targets related to DN. Subsequently， we constructed a "drug-ingredient-target-disease" network for QDTS in the treatment of DN to systematically elucidate the mechanism. The db/db mice were assigned into the model， QDTS （3.34 g·kg-1）， and losartan capsules （10.29 mg·kg-1） groups， and db/m mice served as the normal group. Each group consisted of 8 mice， and they underwent continuous intervention for 8 weeks. After the last administration， mice were euthanized， and the urinary albumin excretion rate （UAER） and renal pathological changes were measured and observed. The expression levels of protein kinase B1 （Akt1）， hypoxia-inducible factor-1 alpha （HIF-1α）， phosphorylated B-cell lymphoma-extra-large （p-Bcl-xl）， as well as autophagy-related indicators microtubule-associated protein 1 light chain 3 （LC3）， ubiquitin-binding protein p62 （p62）， and autophagy-related gene 6 homolog （Beclin1）， were determined. Furthermore， mouse podocytes were divided into the normal glucose （5.5 mmol·L-1）， high glucose （35 mmol·L-1）， DMSO （35 mmol·L-1 glucose+200 mg·L-1 DMSO）， and QDTS （35 mmol·L-1 glucose+200 mg·L-1 QDTS freeze-dried powder） groups. After 48 h of intervention， the protein levels of Akt1， HIF-1α， p-Bcl-xl， LC3， p62， and Beclin1 in podocytes were measured. ResultQDTS had 34 active components acting on 143 targets in the treatment of DN， and 55 targets were related to autophagy， in which Akt1， HIF-1α， and Bcl-xl were the key targets. Compared with the normal group， mice in the model group exhibited significantly increased UAER， glomerular hypertrophy， deposition of blue collagen fibers， thickening of the glomerular basement membrane， and noticeable fusion of podocyte foot processes in some segments. Furthermore， the modeling up-regulated the protein levels of p-Akt1， HIF-1α， and p62 and down-regulating the protein levels of p-Bcl-xl， LC3， and Beclin1 in the renal tissue （P<0.05）. Compared with the model group， QDTS and losartan decreased UAER （P<0.05） and alleviated the pathological damage in the renal tissue. Moreover， QDTS and losartan down-regulated the protein levels of p-Akt1， HIF-1α， and p62 and up-regulated the protein levels of p-Bcl-xl， LC3， and Beclin1 in the renal tissue （P<0.05）. In comparison to the normal glucose group， the high glucose group displayed up-regulated protein levels of p-Akt1， HIF-1α， and p62 and down-regulated protein levels of p-Bcl-xl， LC3， and Beclin1 in podocytes （P<0.05）. Compared with the high glucose group， QDTS down-regulated the protein levels of p-Akt1， HIF-1α， and p62 and up-regulated the protein levels of p-Bcl-xl， LC3， and Beclin1 in podocytes （P<0.05）. ConclusionQDTS alleviates podocyte damage and reduced urinary protein in DN by regulating the Akt1/HIF-1α/Bcl-xl signaling pathway， thereby enhancing podocyte autophagy.
RESUMEN
ObjectiveTo explore the effect of Youguiwan on the rats with adriamycin-induced nephrotic syndrome （NS） and its mechanism. MethodSD rats were randomly divided into a normal group， a model group， three Youguiwan low， medium， and high-dose groups， and a prednisone group. Rats in the model group were intravenously injected with adriamycin in the tail vein to induce the NS model. Rats in the Youguiwan low， medium， and high-dose groups were given 2.8， 5.6， 11.2 g·kg-1·d-1 of crude drugs， respectively， and rats in the prednisone group were given 6.3 mg·kg-1·d-1 of prednisone acetate. Each administration group was given continuous medicine for 6 weeks， and the normal group and model group were given an equal volume of normal saline. Bicinchoninic acid （BCA） assay was used to detect 24 h urine protein （24 h UP）. Automatic biochemical analyzer was used to detect serum urea nitrogen （BUN）， creatinine （SCr）， albumin （ALB）， total cholesterol （TC）， and triglyceride （TG） levels. Hematoxylin-eosin （HE） staining was used to observe renal tissue morphology， and kit was used to detect serum advanced oxidized protein products （AOPPs） and reactive oxygen species （ROS）. Western blot was used to detect the receptor of advanced glycation endproducts （RAGE） of renal tissue， nuclear factor-κB （NF-κB） phosphorylation levels， Wnt， and β-catenin protein expression. ResultAs compared with the normal group， 24 h UP， serum BUN， SCr， TC， TG， AOPPs， and ROS levels in the model group increased significantly （P<0.01）， whereas ALB decreased （P<0.01）. There were typical pathological injuries in the renal tissue， and the expressions of RAGE， phosphorylation（p）-NF-κB， Wnt1， and β-catenin protein were significantly increased （P<0.01）. As compared with the model group， the 24 h UP， serum BUN， SCr， TC， TG， AOPPs， and ROS levels of rats in the Youguiwan low， medium， and high-dose groups significantly reduced （P<0.01）， and ALB significantly increased （P<0.01）. The renal tissue damage was reduced， and the expressions of RAGE， p-NF-κB， Wnt1， and β-catenin protein were significantly decreased （P<0.01） in a dose-dependent manner. ConclusionYouguiwan improves the kidney injury of rats with adriamycin-induced NS. The mechanism may be related to the reduction of AOPPs level， inhibition of RAGE/ROS/NF-κB axis， and activation of Wnt/β-catenin signal.

Objective To explore the effect of regional synergistic treatment system on the treatment time and short-term prognosis of patients with ST-segment elevation myocardial infarction (STEMI).Methods A retrospective analysis of the clinical data of STEMI patients who admitted to emergency center of Suzhou Kowloon Hospital Affiliated to Shanghai Jiaotong University School of Medicine and underwent primary percutaneous coronary intervention (PPCI) from January 2013 to January 2017 were conducted. All patients were divided into two groups, group A was the patients who underwent the PPCI before the establishment of the acute chest pain area co-treatment system (from January 2013 to December 2014), and group B was the patients who received the treatment after the establishment of the area co-treatment system (from January 2015 to January 2017). The length of time from onset of symptoms to the balloon dilatation (S2B), the length of time from the first medical contact to the balloon dilatation (FMC2B), the length of time from entering the gate of hospital to the balloon dilatation (D2B), and the incidence of 90-day end point events (including heart failure, all-cause death, and other related adverse events) were collected. The relations of the establishment of the acute chest pain area co-treatment system and the incidence of 90-day end point events were analyzed by multivariable Logistic regression analysis.Results Among the 221 enrolled patients with STEMI, 83 patients were in group A and 138 patients were in group B respectively. Compared with group A, S2B time [minutes: 180 (140, 210) vs. 201 (154, 225)], FMC2B time [minutes: 89 (78, 100) vs. 94 (83, 107)] and D2B time [minutes: 66 (62, 70) vs. 85 (72, 99)] were significantly shortened in group B (allP < 0.05), the incidence of 90-day end point events were significantly decreased (heart failure:20.3％ vs. 32.5％, all-cause death: 1.4％ vs. 7.2％, other related adverse events: 23.2％ vs. 36.1％, allP < 0.05). It was shown by multivariable Logistic regression analysis that the establishment of the acute chest pain area co-treatment system could lower the incidence of 90-day end point events [heart failure: odds ratio (OR) = 1.904, 95％ confidence interval (95％CI) = 0.968-1.004, P = 0.048; all-cause death:OR = 11.724, 95％CI = 0.955-1.048,P = 0.013; other related adverse events:OR = 1.925, 95％CI = 1.049-3.530,P = 0.034].Conclusion The construction of regional synergistic treatment system can shorten the emergency treatment time of STEMI patients and reduce the incidence of 90-day end point events including heart failure and death.
