2. Changes of telomerase activity during differentiation of human mesenchymal stem cells into adipocytes
Academic Journal of Second Military Medical University 2011;32(2):123-127
Objective: To study the telomerase activity changes during the differentiation of human mesenchymal stem cells (MSCs) into adipocytes and the related mechanism. Methods: Human MSCs were isolated from human bone marrow by plastic adhesion and were characterized by immune phenotyping. The multilineage differentiation potential of MSCs was confirmed by inducing MSCs to differentiate into osteoblasts and neuron-like cells by corresponding agents. Telomeric repeat amplification protocol (TRAP) assay was performed to examine telomerase activity in MSCs during adipogenic differentiation of MSCs; Western blotting analysis was used to examine the protein expression levels of hTERT, TRF1, and Tankyrase 1. Results: TRAP showed that telomerase was negative in MSCs, but greatly up-regulated during the adipogenic differentiation process, peaked on the 7th day after adipogenic differentiation of MSCs(P<0.05), and then decreased thereafter. Western blotting analysis showed slight hTERT expression in MSCs, and the expression of hTERT and Tankyrase 1 increased during the adipogenic differentiation process, peaked on the 7 th day, and gradually decreased thereafter. The expression of TRF1 remained unchanged. Conclusion: Telomerase is weakly expressed in MSCs; the expression is increased during the adipogenic differentiation process of MSCs and then gradually decreases; and Tankyrase 1 may play an important role during the process.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

Objective To investigate effect of low molecular weight heparin (LMWH)on oxidative stress and renal function in elderly patients undergoing gastrectomy of stomach neoplasms. Methods 90 elderly patients undergoing radical surgery were randomly divided into LMWH group (Ⅰ group,n=45)and control group (Ⅱ group,n=45). Patients inⅠ group received a subcutaneous injection of LMWH(100 u/kg,1/d)from the time before anesthesia induction to postoperative 5 days,and patients in Ⅱ group were given equal volume of saline. Venous blood samples were collected to determine level of malondialdehyde(MDA),aldose reductase(AR)activity level,superoxide dismutase(SOD)activity level,catalase (CAT)activity level,creatinine(Cr)and blood urea nitrogen(BUN)before anesthesia induction(T0 ),at the end of the surgery(T1 ),on postoperative 1 day(T2),3 days(T3)and 5 days(T4)respectively;urine specimen were also collected to measured albumin(Alb)and N-acetyl-beta-D-amino glycosidase enzymes(NAG)at the same time points. Results There were obvious statistical differences in MDA,AR,SOD and CAT at different time points by intra-group comparison (P<0.05 ). MDA and AR rose first and then fell in two groups,and both reached the peak at T2 ,whereas SOD and CAT had the opposite trends. There were obvious statistical differences in MDA,AR,SOD and CAT at T1 ~T3 (P<0.05 ). MDA and AR inⅠgroup at T1 ,T2 and T3 was lower than those in groupⅡ(P<0.05 ),whereas SOD and CAT inⅠgroup at T1 ,T2 and T3 were significantly higher than those in group Ⅱ(P<0.05). Cr and BUN of both groups were found no significant statistical difference within the group and between groups(P>0.05).Alb/Cr of both groups at T1 and T2 were significantly higher than those at T0 (P<0.05 ),while Alb/Cr in Ⅰ group at T1 was obviously lower than Ⅱgroup(P<0.05 ).NAG/Cr in both groups at T1 ,T2 and T3 were significantly higher than those at T0 (P<0.05 ),while NAG/Cr inⅡ group at T4 was still higher than that at T0 (P<0.05 ),and NAG/Cr inⅠgroup at T1 ~T4 was obviously lower thanⅡgroup (P<0.05 ). MDA and AR in both groups at T1 ,T2 were positively correlated with Alb/Cr and NAG/Cr respectively(P<0.05 ),whereas SOD and CAT in both groups at T1 ,T2 were negatively correlated with Alb/Cr and NAG/Cr respectively(P<0.05 ). Conclusion Oxidative stress reaction resulted from radical surgery of elderly patients is associated with perioperative renal damage. LMWH could reduce oxidative stress in elderly patients,and alleviate the kidney damage,as well as protect the renal function.

It is a thorny problem of modern medicine that the in-stent restenosis (ISR) after percutaneous coronary intervention (PCI). Combining with the etiology and pathogenesis of TCM, Professor LIU Zhong-yong believes that the root cause of ISR after PCI is the deficiency syndrome: menstruation gradually dying up, the heart yang qi deficiency; and the direct cause is excess syndrome: endogenous turbidity syndrome, heart vessel blockage. The cause for the formation of turbidity syndrome is cold, phlegm, blood stasis, poison, and dampness. Depending on the clinical manifestations, five kinds of syndromes were divided: cold turbidity stagnation, phlegm turbidity resistance, blood stasis blockage veins, poison turbidity, and dampness turbidity resistance. Professor LIU Zhong-yong also proposed relevant treatment for both symptoms and root causes, which provided new ideas and experience in the integrated TCM and Western medicine for ISR after PCI.
