ABSTRACT
Sepsis is defined as an organ dysfunction caused by systemic inflammatory response induced by infection,and may eventually developed into multiple organ failure (MOF).The onset of sepsis often involves the activation of inflammatory cells,over expression of inflammatory cytokines,immune dysfunction,damage of tissue and organ,excessive apoptosis of cell.Mesenchymal stem cells (MSCs) have a wide range of biological activities,including anti-inflammatory,antibacterial,immune regulation,regeneration and repair of tissue and organ,anti-apoptosis,etc.In recent years,a large number of preclinical studies had demonstrated that MSCs has good actions on sepsis.The purpose of this review is to describe the mechanism of MSCs in the treatment of sepsis,and to point out the possible clinical challenges.
ABSTRACT
Objective To study the asymmetric dimethylarginine(ADMA) concentrations in plasma of acute coronary syndrome (ACS) and its various subgroups ,and analyze the relationship between ADMA and traditional risk factors of ACS .Methods 101 ACS patients were enrolled in the study ,which were divided into several subgroups according to clinical diagnosis ,ECG and coro‐nary angiography .ACS group were divided into unstable angina(UA) group(n=70) and acute myocardial infarction(AMI) group (n=31) ,then AMI group was divided into non‐ST segment elevation myocardial infarction(NSTEMI) group(n=19) and ST seg‐ment elevation myocardial infarction (STEMI) group(n=12) .The control group(n= 40) were recruited in the study during the same period ,who showed normal coronary arteries in coronary angiography .All the patients received coronary attery angiography . The plasma ADMA concentration was measured by using enzyme‐linked immunosorbent assay (ELISA) ,and serum contents of lip‐id(TC ,TG ,HDL‐C ,LDL‐C) ,C‐reactive protein(CRP) ,troponin were detected by automatic biochemic analysis apparatus .Results Compared with the control group ,plasma ADMA concentration of ACS group increased ,the difference was statistically significant (P<0 .05) .The concentrations of ADMA in AMI group and UA group were higher than those in control group ,and the difference was statistically significant(P< 0 .05) .The concentrations of ADMA in AMI group were significantly higher than those in UA group(P<0 .05) .Plasma ADMA negatively correlated with HDL‐C concentrations(r= -0 .222 ,P<0 .05) ,positively correlated with LDL‐C concentration(r=0 .357 ,P<0 .05) ,and positively correlated with CRP(r=0 .619 ,P<0 .05) .Conclusion The occur‐rence of ACS and some of its related risk factors are correlated with plasma ADMA concentration .
ABSTRACT
Objective To explore the feasibility and validity of Satir model on compulsory drug rehabilitation for female drug users in closed settings. Methods Satir Model-based group psychotherapy was adopted in the treatment on 33 female drug users. Results The findings are that the pre-treatment SCL-90 scores were all higher than norm,indicating very high significant differences(P＜0.01) ; while the post-treatment SCL-90 scores,except the score of somatization, were approximate to norm, showing no statistical differences(P ＞0. 05). Conclusion Satir model played a positive role in the process of female drug users mental health recovery.
