RESUMEN
Objective To investigate the pharmacodynamic effects of Poria triterpenes on tumor suppression in mice with ascites tumors,and to detect and identify the chemical components of Poria triterpenes using HPLC-LTQ-Orbitrap method,and to explore the potential mechanism of action of Poria triterpenes on tumor suppression in mice with ascites tumors based on both of them using non-labeled definitive proteomics techniques.Methods Poria triterpene parts were extracted by solvent method,and the main components were detected and identified by HPLC-LTQ-Orbitrap liquid mass spectrometer;mice were randomly divided into model group,Poria triterpene group and positive control group(mushroom polysaccharide group),after 21 days of continuous administration,to establish After continuous administration for 21 days,the H22 ascites tumor mouse model was established,and the effect of each drug group on the amount of ascites,spleen index,thymus index,liver index,serum TNF-Alpha and IL-2 in H22 ascites tumor mice was observed after one week of continued administration;then H22 cells were extracted from the ascites of mice,and the H22 cells in the model group and Poria triterpene group were detected by non-lable-free quantitative proteomics technique.The differentially expressed proteins(DEPs)were screened out by using GO,KEGG and other analyses.Results The abdominal water volume in the mouse Poria triterpene group was significantly lower than that in the model group(P<0.05);the thymus index in the mouse Poria triterpene group was significantly higher than that in the model group(P<0.05);the serum levels of TNF-Alpha in the mouse Poria triterpene group were significantly different from those in the model group(P<0.01),and the serum levels of IL-2 in the mouse Poria triterpene group were significantly different from those in the model group(P<0.01).Through the analysis of the chemical composition of Poria triterpene parts,a total of 19 triterpenoids were identified,with four main structural types.A total of 188 differentially expressed proteins were identified in the Poria triterpene group compared with the model group,of which 86 differentially expressed proteins were up-regulated and 102 differentially expressed proteins were down-regulated;GO database analysis showed that the differentially expressed proteins in the Poria triterpene group were mainly involved in the regulation of interleukin-1 production The KEGG database analysis showed that the differentially expressed proteins in the Poria triterpene group were involved in signaling pathways closely related to tumor,mainly MAPK,Apoptosis,mTOR,Wnt and p53 pathways,etc.The genes coding for the seven representative differential proteins were validated at the mRNA level by RT-qPCR.Conclusion The pharmacodynamic study found that Poria triterpenes had tumor suppressive effect on H22 ascites tumor mice,then by proteomics found Poria triterpenes group ascites H22 cell protein compared to the model group changed significantly,the study thus showed that Poria triterpenes for mice ascites tumor mechanism of tumor suppressive effect mainly involves apoptosis,inflammatory response and immune process.
RESUMEN
Objective To investigate the clinical treatment strategy of concomitant diseases and perioperation complications in elderly patients with hip fracture aged ≥ 80 years and the clinical prognosis.Methods A retrospective analysis was conducted in 95 hip fracture patients aged 80 and over years(80～90 years old) undergoing operation.There were 42 cases with femoral neck fractures and 53 cases with intertrochanteric fracture.71 cases (74.7％) had preoperative concomitant medical diseases.Screw fixation was performed in 3 cases (3.2％),hemiarthroplasty in 75 cases (78.9％),total hip replacement in 4 cases (4.2％),proximal femoral nail antirotation (PFNA) in 9 cases (9.5 ％) and reconstruction interlocking nail fixation in 4 cases (4.2 ％).Results No mortality was found during hospitalization.Postoperative anemia was the most common (74.7％),followed by hypoproteinemia (68.4％),digestive disorders (30.5％),electrolyte disturbance (28.4％) and psychiatric symptoms (15.8 ％).At least one-year follow-up was made in 73 cases.39 cases (53.4 ％) acquired independent activities after surgery,48 (65.8％) patients recovered to the preoperative level of activity.The concomitant diseases before surgery (OR =0.23,P =0.011),preoperative ability of activity (OR=0.23,P=0.025),the American Society of Anesthesiology (ASA) classification (OR=0.19,P=0.025) were the related factors influencing the one-year mortality.Conclusions The treatment of concomitant diseases should be emphasized in treating fracture.The active prevention during preoperative,intraoperative,postoperative period could reduce or avoid fatal complications and acquire good functions.
RESUMEN
AIM: To Establish the standard of Qirong Medicinal Wine (Radix Angelicae Sinensis, Fructus Psoraleae, Radix Polygoni Multiflori Preparata, Fructus Lycii and Flos Carthami, etc.). METHODS: Radix Angelicae Sinensis, Fructus Psoraleae, Radix Polygoni Multiflori Preparata, Fructus Lycii and Flos Carthami in the preparation were identified by TLC. Psoralen and isopsoralen were determined by HPLC. RESULTS: The average recoveries of psoralen and isopsoralen were 98.7% and 100.8%, respectively., RSD were 2.18%( n =5) and 1.67%( n =5),respectively. CONCLUSION: The methods are simple, accurate and reproducible.
