1.Advances of anaplastic lymphoma kinase in non-small cell lung cancer
Journal of International Oncology 2014;(8):592-595
Targeted therapy is the most prospective part of the research related to the treatment of non-small cell lung cancer(NSCLC). After epidermal growth factor receptor(EGFR),anaplastic lymphoma kinase (ALK)gene is expected to become a new target in the treatment of NSCLC. Moreover,several related resear-ches suggest that ALK inhibitor(crizotinib)is effective for treatment of ALK-rearranged NSCLC. Therefore,it is important to review the detection method of ALK gene,clinicopathologic features and the research progress of ALK inhibitor for the individual treatment of NSCLC.

China Journal of Chinese Materia Medica 2014;39(1):80-82
Angelicae Sinensis Radix, dried roots of Angelicae sinensis, is a well-known traditional Chinese medicine. Six compounds were isolated and purified by silica gel and preparative HPLC. According to physicochemical properties and spectral data, the compounds were identified as senkyunolide H-7-acetate (1), o-phthalic acid (2), diisobutyl phthalate (3), p-hydroxyphenylethanol ferulate (4), ferulic acid (5) and coniferylferulate (6). Compound 1 was a new one.

Objective To establish a method for determining cinnamaldehyde in Zegui Longshuang Capsules. Methods A C18 column was used with Acetonitrile-Water (30∶70) as the mobile phase,and the detection wavelength was at 290 nm. Results The calibration curve of cinnamaldehyde was linear from 0.010 ?g to 0.507 ?g,and r=0.999 9. The average recovery was 98.55 %with RSD being 2.06 %. Conclusion This method is proved to be accurate and reliable,and can be used to control the quality of Zegui Longshuang Capsules.

Objective To establish a mathematical model to describe the skeletal class Ⅲ malocclusion of patient dental and basal bone arch form, for providing a data reference and basis for further study. Methods Thirty-five patients with skeletal classⅢmalocclusion were selected in this study for computed tomography CBCT. The data of 3-D image were analyzed, and dental arch marker (Fa) and base bone arch marker (Ba) were determined. The reference plane was determined by least square method. Software Matlab 7.0 was used to calculate two-dimensional coordinate system. Based on this, a mathematical model was established to describe the dental and basal bone arch form and then to validate the mathematical model. Results (1) The mathematical model can be used to describe the dental arch form of skeletal classⅢmalocclusion, maxillary:Y=46.12 [1-(2X/70.99)2]1.052;mandibular:Y=39.16 [1-(2X/64.51)2]1.038. (2) The mathematical model can be used to describe the basal bone arch form of skeletal classⅢmalocclusion, maxillary:Y=43.14 [1-(2X/75.09)2]1.061;mandibular:Y=39.03 [1-(2X/60.63)2]1.021. (3) Fa was located at Ba labial side in the maxilla, the distance was positive. Fa was located at Ba lingual side in the mandibular, and the distance was negative. (4) The fitting correlation coefficient of beta-function curve and each tooth on the dental and basal bone arch of skeletal class Ⅲ malocclusion were greater than 0.7 (P<0.05). Conclusion In this study, the mathematical model can be used to describe the dental and basal bone arch form of the skeletal classⅢmalocclusion, which can guide further research.

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 .
