This study was aimed to observe the effect of Danzhi Jiangtang Capsule ( DJC ) on expression of solu-ble thrombomodulin ( sTM ) and soluble endothelial cell protein C receptor ( sEPCR ) in experimental rats of type 2 diabetes mellitus (T2DM). This study also explored possible mechanisms of Yiqi Yangyin Huoxue method on vascular endothelial tissue and discussed mechanisms of prevention and management of T2DM vascular lesions . A total of 60 male Sprague-Dawley ( SD ) rats were fed for one week and then randomly divided into the nor-mal control group ( group N , n = 12 , rats were fed with routine food ) and diabetes mellitus group ( n = 48 , rats were fed with high-fat diet). After 4 weeks, rats in the diabetes mellitus group were injected with strepto-zotocin ( STZ ) to induce T2DM . According to the blood glucose level , rats were divided into three groups , wh ich were the model group (group M), pioglitazone (group P), and pioglitazone combined with DJC (group D). Group P was treated with pioglitazone (10 mg?kg-1?d-1), group D was given pioglitazone (10 mg?kg-1?d-1) and DJC ( 0 . 47 g?kg-1?d-1 ) . The group N and group M were treated with sodium chloride ( 5 mL?kg -1?d-1 ) . After four-week drug administration , the levels of sTM , sEPCR , PT , APTT and FIB in each group were tested . The results showed that compared with the control group , the levels of sTM , sEPCR and FIB in group M , group P and group D were significantly increased ( P < 0 . 05 ) , and the levels of PT and APTT were obviously reduced ( P < 0 . 05 ) . Compared with group P , the levels of sTM , sEPCR , FIB of group D were significantly reduced ( P< 0 . 01 ) , and the level of APTT was significantly increased ( P < 0 . 05 ) . However , there was no significant dif-ference in the increasing of PT. It was concluded that the Yiqi Yangyin Huoxue method can reduce the levels of sTM and sEPCR , and effectively improve coagulation . The possible mechanisms of protective effect on the vascular endothelium can be from reducing levels of sTM and sEPCR in order to enhance the activity of anti-coagulation and fibrinolysis , regulate the function of blood coagulation to improve hypercoagulable state .

Objective To evaluate the curative effect and security ofYangxue-Qingnao granules on posterior circulation ischemia.Methods 52 patients with posterior circulation ischemia from September 2012 to January 2014 in Remin hospital of Wuhan Universityk, were randomly recruited into a control group and a treatment group, with 26 cases in each group. The control group was only treated with flunarizine HCL and Betahistine Mesilate Tablets, while the treatment group was givenYangxue-Qingnao granules based on the control group. The change of clinical symptoms, TCD and cervical vascular ultrasound were observed before and after the treatment.Results After the treatment, the total effective rate of treatment group was significantly different to the control group (96.2%vs. 76.9%;χ2=4.127,P=0.042). The changes of blood flow velocity of vertebral artery, basilar artery and posterior inferior cerebellar artery were all decreased after the treatment in both groups (tvalue in the treatment group were 20.624, 13.773, and 9.485 respectively,t value in the control group were 13.203, 9.550, and 5.655, respectively, allP<0.01), besides such decreases in the treatment group were better than the control group (allP<0.01). After the treatment, the condition of carotid IMT decrease was significantly better in the treatment group than the control group (the number rate of IMT decrease was (96.2%vs. 69.2%;χ2=5.318,P=0.021).ConclusionYangxue-Qingnao granules can obviously improve the blood flow velocity and the thickness of IMT in patients with posterior circulation ischemia. The short-term curative effect is obvious.

OBJECTIVETo explore the proliferation and invasive effects of inhibitors of kinase 4(INK4)(P15(ink4b) and P16(ink4a)/CDKN2) gene protein activation on RKO human colorectal cell in vivo and in vitro.
METHODSRKO human colorectal cell line was exposed to the specific DNA methyltransferase inhibitor 5-Aza-CdR and INK4(P15(ink4b) and P16(ink4a)/CDKN2) protein expression was detected by Western blotting. Soft agar cloning experiment and Transwell chamber assay were used to detect the proliferative and invasive ability in vitro. Tumorigenicity in nude mice was analyzed in vivo.
RESULTSINK4(P15(ink4b) and P16(ink4a)/CDKN2) protein expression of RKO human colorectal cells after exposure to 1×10(-7), 5×10(-7) and 1×10(-6) mol/L 5-Aza-CdR concentrations(A, B, C groups) were 1.13, 1.38, 1.92 folds and 1.11, 1.45, 2.14 folds compared to positive control group respectively. Soft agar cloning experiment showed the number of cell colony significantly decreased from 36.8±5.1(positive control group) to 32.4±7.2, 21.3±5.4 and 19.5±6.4 (3 experiment groups, all P<0.05) respectively. Transwell chamber assay showed that migrated cell number in positive control group(67.4±7.2) was significantly higher than those of 3 experimental groups(35.3±4.6, 29.5±7.3 and 25.3±6.2, respectively). The tumor volume of metastasis model in nude mice was inhibited in experimental groups, but not significantly lower compared to control group (P>0.05). There were significant differences of tumor weight and inhibition rate between control group and 3 experimental groups in nude mice respectively(all P<0.01).
CONCLUSIONINK4(P15(ink4b) and P16(ink4a)/CDKN2) protein activation can inhibit tumor proliferation, migration and suppress the tumor formation ability.

Objective To observe the changes of short-chain acyl-CoA dehydrogenase (SCAD) expression on human umbilical vein endothelial cell (HUVEC) apoptosis and investigate its relationship with apoptosis. Methods The HUVEC was cultured normally for 2-3 days. The apoptotic model of HUVEC was established by tert-butyl hydrogen peroxide (tBHP). The HUVEC was treated by different concentrations of tBHP (0, 10, 20, 30, 40, 50 μmol/L) for 12 hours and different time (0, 3, 6, 9, 12 hours) with 50 μmol/L tBHP to establish the apoptotic model of HUVEC. The cell viability was detected by methyl thiazolyl tetrazolium (MTT), the mRNA expression of SCAD was determined by real-time polymerase chain reaction (PCR), the protein expression of SCAD was achieved by Western Blot. The best concentrate and time were determined to interfere the HUVEC to achieve the apoptotic model of HUVEC. The SCAD gene of HUVEC was knocked down by RNA interference sequence (siRNA274, siRNA414, siRNA679). The mRNA expression of SCAD, the protein expression of SCAD and the activity of SCAD enzyme were detected to achieve the best RNA interference sequence. The HUVEC was intervened by the best RNA interference sequence and tBHP. The cell activity and apoptosis rate, the enzyme activity of SCAD, the mRNA and protein expression of SCAD, the contents of reactive oxygen species (ROS), aderosine triphosphate (ATP) and free fatty acid (FFA) were detected to observe the effect of SCAD on apoptosis of HUVEC. Results ① The cell viability, the mRNA expression and the protein expression of SCAD were decreased gradually in a concentration and time dependent manner with the increase of tBHP concentration and the prolongation of intervention time. The decline was most significant in the group of the 50 μmol/L tBHP to interfere HUVEC for 12 hours. ② The siRNA679 transfection was the most significant in reducing SCAD mRNA and protein expressions among the three interference sequences (siRNA274, siRNA414, siRNA679). ③ Compare with blank control group, the cell viability was significantly decreased in the siRNA679 group (A value: 0.48±0.09 vs. 1.00±0.09, P < 0.01), the apoptotic rate of HUVEC was significantly increased [(29.96±2.09)% vs. (2.90±1.90)%, P < 0.01], the expression of SCAD mRNA and SCAD protein, the activity of SCAD enzyme and the content of ATP were significantly decreased [SCAD mRNA (2-ΔΔCt): 0.50±0.16 vs. 1.34±0.12, SCAD/α-Tubulin: 0.67±0.11 vs. 1.00±0.06, the activity of SCAD enzyme (kU/g): 0.38±0.04 vs. 0.53±0.04, the content of ATP (μmol/g): 0.14±0.02 vs. 0.19±0.01, all P < 0.05], the contents of FFA and ROS were significantly increased [FFA (nmol/g): 0.84±0.07 vs. 0.47±0.04, ROS (average fluorescence intensity): 647.5±23.7 vs. 434.2±46.5, both P < 0.01]. Meanwhile, SCAD siRNA treatment triggered the same apoptosis as HUVEC treated with tBHP. Conclusions Down-regulation of SCAD may play an important role in HUVEC apoptosis. Increase in the expression of SCAD may become an important part in intervening HUVEC apoptosis.
