BACKGROUND:Human umbilical cord blood-derived mesenchymal stem cels can be induced through the co-culture to differentiate into other cels, but how to get more seed cels for tissue engineering is one of the most difficult problems. OBJECTIVE: To investigate the role of the different concentrations of thyroxine in chondrogenic differentiation of human umbilical cord blood-derived mesenchymal stem cels by co-culture with rabbit chondrocytes. METHODS:Human umbilical cord blood-derived mesenchymal stem cels were co-cultured with rabbit chondrocytes at 2:1, and stimulated by medium containing different concentrations of thyroxine (0, 0.01, 0.1 and 1, 10 μmol/L). Co-cultured cels with no thyroxine served as control group. After 14 days of co-culture, the cel RNA and protein were extracted, mRNA expressions of aggrecan and colagen type II were detected by real-time PCR, and protein expression of aggrecan and colagen type II were detected by western blot assay. RESULTS AND CONCLUSION:After intervention with 0.01, 0.1, 1, 10 μmol/L thyroxine, the mRNA and protein expressions of aggrecan and colagen type II were enhanced with the increase of thyroxine concentration, which were significantly different from those in the control group (P < 0.05). Experimental findings indicate that high levels of thyroxine can enhance the chondrogenic ability of human umbilical cord blood-derived mesenchymal stem cels co-cultured with rabbit chondrocytes.

Hepatic ischemia/reperfusion injury is an important restricting factor of clinical liver resection and liver transplantation.When the liver is transiently deprived of blood followed by repeffusion,a large number of various mediators are released that can lead to cellular and,eventually,organ dysfunction.This review summarizes the pathogenesis and the protection mechanisms of hepatic ischemia/reperfusion injury.

Objective To explore the value of strain rate imaging (SRI) technology in the diagnosis of hypertension patient with re-gional left ventricular early diastolic dysfunction. Methods 50 essential hypertension patients were divided into hypertension Group Ⅰ and Group Ⅱ, including 31 patients with normal left ventricular and 19 patients with left ventricular hypertrophy. 25 healthy people were used as the control group. SRI was done in the six different basal myocardial segments and the parameters of SRI were compared with that of Doppler tissue imaging (DTI) and pulse Doppler (PW). Results In the hypertension group, SRe of the six different basal myocardial segments was lower than that in the control group (P<0.05), but (SRa) of hypertension group was higher (P<0.05). SRe was negatively correlated with the patients'illness development (r=-0.89, P<0.05), but SRa was positively correlated (r=0.97, P<0.05). And the SRe/SRa<1 detection rate of Group Ⅱ was higher than that in Group Ⅰ, and the ratio in the control group was lowest(P<0.05). Total detection rate of SRI (88%) was higher than Em/Am <1 of DTI (79.67%) and E/A < 1 of PW(60%), and these changes were more obvious in Group Ⅰ. SRI was higher than DTT and PW (P<0.05). Conclusion Compared with traditional technology and methods, SRI could pro-vide more accurate diagnoses to hypertension patient with regional left ventricular early diastolic dysfunction.

Objective:To study the effects of phentolamine and dopamine combined with cardiopulmonary resuscitation on the patients with cardiac arrest.Methods:60 patients with cardiac arrest who were treated from February 2015 to April 2016 in our hospital were selected and divided into the control group and the observation group according to different treatment methods.The control group was treated with routine treatment.while the observation group was treated with phentolamine and dopamine based on the control group.The changes ofcTnI,CK,CK-MB levels,MDA,SOD concentration and hemodynamics were observed before and after treatment.Results:After treatment,the total mortality was 20％ in the observation group,which was significantly lower than that of the control group (33.33％,P＜0.05).The levels of cTnI in the observation group were significantly lower than those of the control group at 2 h and 24 h after the cardiopulmonary resuscitation(P＜0.05).After the cardiopulmonary resuscitation,the serum levels of CK and CK-MB in the observation group were significantly lower than those in the control group (P＜0.05).The concentration of MDA and SOD in the observation group were significantly higher compared with the control group [(1.86± 1.65) μg/L vs(3.81± 1.24) μg/L、(6.58± 0.95)μg/L vs(3.74± 0.56) μg/L](P＜0.05).After the cardiopulmonary resuscitation,the MAP value of observation group was significantly higher than that of the control group (P＜0.05).The CO value and CI value of observation group were significantly increased from the 6th day to the control group (P＜0.05),and the PCWP values of observation group were significantly lower than those of the control group (P＜0.05).Conclusion:Phentolamine combined with dopamine could effectively improve the cardiac hemodynamics and prognosis of patients with cardiac arrest,reduce the myocardial injury and enhance the survival with high safety.
