Shen Qi Wan attenuates renal interstitial fibrosis through upregulating AQP1 / 中国天然药物

Renal interstitial fibrosis (RIF) is the crucial pathway in chronic kidney disease (CKD) leading to the end-stage renal failure. However, the underlying mechanism of Shen Qi Wan (SQW) on RIF is not fully understood. In the current study, we investigated the role of Aquaporin 1 (AQP1) in SQW on tubular epithelial-to-mesenchymal transition (EMT). A RIF mouse model induced by adenine and a TGF-β1-stimulated HK-2 cell model were etablished to explore the involvement of AQP 1 in the protective effect of SQW on EMT in vitro and in vivo. Subsequently, the molecular mechanism of SQW on EMT was explored in HK-2 cells with AQP1 knockdown. The results indicated that SQW alleviated kidney injury and renal collagen deposition in the kidneys of mice induced by adenine, increased the protein expression of E-cadherin and AQP1 expression, and decreased the expression of vimentin and α-smooth muscle actin (α-SMA). Similarly, treatmement with SQW-containing serum significantly halted EMT process in TGF-β1 stimulated HK-2 cells. The expression of snail and slug was significantly upregulated in HK-2 cells after knockdown of AQP1. AQP1 knockdown also increased the mRNA expression of vimentin and α-SMA, and decreased the expression of E-cadherin. The protein expression of vimentin increased, while the expression of E-cadherin and CK-18 significantly decreased after AQP1 knockdown in HK-2 cells. These results revealed that AQP1 knockdown promoted EMT. Furthermore, AQP1 knockdown abolished the protective effect of SQW-containing serum on EMT in HK-2 cells. In sum, SQW attentuates EMT process in RIF through upregulation of the expression of AQP1.

Research progress of related signaling pathways of treating Alzheimer disease by TCM / 国际中医中药杂志

In recent years, Traditional Chinese Medicine (TCM) treatment for Alzheimer's disease has been widely concerned. At present,there are more studies on the following 6 pathways: brain-derived neurotrophic factor (BDNF)/tyrosine kinase B (TrkB) signaling pathway, phosphatidy linositol-3-kinases (PI3K)/protein kinase B (Akt) signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, protein kinase A (PKA)/cAMP response Element binding protein (CREB) signaling pathway,nuclear factor-κB (NF-κB) signaling pathway, Wnt signaling pathway.

Analysis of 58 Cases of ADR/ADE with Cardiac Damage Induced by Metranidazole / 中国药房

OBJECTIVE:To explore the characteristics and regularities of cardiac damage induced by metranidazole,and pro-vide reference for clinical safe application. METHODS:In retrospective study,58 cases of cardiac damage caused by metranidazole in Henan ADR Monitoring Center for Drug from Jan. 2010 to Dec. 2015 were analyzed statistically. RESULTS:In 58 cases of cardiac damage induced by metranidazole,25 cases were male,33 were female,the ratio of male to female was 0.76∶1,the patients with ADR/ADE aged 15-64 years (74.14%),most were intravenous administration (79.31%) and happened within 30 min (70.69%), cardiac damage mainly manifested as palpitation,severe cases can cause tachycardia and arrhythmia,the ADR improved or cured af-ter withdrawal or symptomatic treatment. CONCLUSIONS:Clinic should strengthen observation of ADR/ADE caused by metranida-zole,especially the monitoring of cardiac toxicity reactions;pharmaceutical manufacturers should improve the drug instructions to in-sure the safety of clinical medication.

Factor sinfluencing the conclusion of research projects in local institutions of higher learning and their countermeasures / 中华医学科研管理杂志

To increase the conclusion rate of scientific research projects and prevent the phenomena of fine start and poor finish,high input and low output,and heavy application and light management therein,by calculating the conclusion rate of the research projects of all levels expired longitudinally undertaken by Fujian Medical University from 2010 to 2012,this thesis analyzes the root cause for the delay of research projects starting from the three parties which sign the research project contract,namely,the competent authority of science and technology,the regulation department of scientific research,and the research group; meanwhile,it puts forward the countermeasures including perfecting the management system of scientific research,implementing effective secondary Strengthen the team management,management of colleges and universities,and strengthening the building of scientific research management team,etc.,in the hope of providing reference for the increase of the conclusion rate of research projects in institutions of higher learning.
