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 .

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 investigate the effect of modified alar reduction with external incision to correct alar hypertrophy.Methods:From January 2017 to January 2019, 16 patients(1 male and 15 females, aged 21 to 39 with alar hypertrophy were treated in the plastic surgery department of the Second Affiliated Hospital of Nanchang University. Modified alar reduction with external incision were applied. In order to rotate the free alar lobules, the incision was extended in nasal lobules to the vestibular floor and remove part of the vestibular tissue of the alar lobules during the operation. Then the free alar was moved into the nostril to make the alar junction shift inward and upward, and reposition the alar junction to correct the alar hypertrophy and the wide nasal base. Photos of patients in frontal, side, and basal view before operation, 1 month, 6 months after operation. Intercanthal distance (ICD)、interinter-alar width (IW)、nasal base width (BW) were measured. The ratios of IW, BW and ICD before operation, 1 month, and 6 months after operation, and the narrowing rate of IW and BW at 1 month and 6 months after operation were summarized. The incision scar was evaluated with reference to the Vancouver Scar Scale. Normally distributed variables were compared using an paired t test. Nonparametric continuous variables were compared using Wilcoxon rank sum test. When P<0.05, the difference is considered statistically significant. Results:Sixteen patients were followed up for 6 to 12 months, averaged of 8 months. The IW/ICD of 16 patients at preoperation, after operation 1 month and 6 months were 1.160±0.080, 1.049±0.047 (0.110±0.049 decrease than before operation) and 1.038±0.047 (0.120±0.049 decrease than before operation). The differences were statistically significant ( P<0.05). The IW constriction rates were 9.3% at 1 month after operation and 10.2% at 6 months after operation. BW/ICD at preoperation, after operation 1 month and 6 months were 1.035±0.047, 0.960±0.039(0.072±0.019 smaller than preoperation), and 0.950±0.034(0.079±0.020 smaller than preoperation). Compared with preoperative data, the difference was statistically significant ( P<0.05). The BW reduction rates were 7.0% at 1 month after operation and 7.6% at 6 months after operation. The Vancouver Scar Scale score was 3(2.25, 3) at 1 month after operation, 1(0.25, 1) at 3 months after operation and 1(0, 1) at 6 months after operation. The differences were statistically significant ( P<0.05). There was a statistically significant difference between 3 months after surgery and 1 month after surgery ( Z=-3.472, P=0.001). There was no statistically significant difference between 6 months after surgery and 3 months after surgery ( Z=-1.414, P=0.157). All patients had no significant postoperative complications such as incision infection, asymmetry of nasal alae, obstruction of nasal ventilation, etc. Postoperative alar and nasal base profiles were significantly improved. Conclusions:Modified alar reduction with external incision can effectively treat alar hypertrophy without obvious postoperative complications. It is a good operation to correct alar hypertrophy.
