To find a new method to identify Mori Cortex and its adulterants by analysis their ITS2 sequence of barcode,total genomic DNA was isolated from Mori Cortex and its adulterants. Nuclear DNA ITS2 sequences were amplified,and purified PCR products were sequenced. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner V3.0. The Kimura 2-Parameter (K2P) distances were calculated us-ing software MEGA 4.0. Identification analyses were performed using BLAST1, Nearest Distance and neighbor-joining (NJ) methods. The results showed the intra-specific genetic distance of Mori Cortex was 0, which were lower than inter-specific genetic distances between Mori Cortex and its closely related species (0.003-0.343). The ITS2 region is an efficient barcode for identification of Mori Cortex and its closely related species, which provides a scientific basis for fast and accurate identification and new method of Mori Cortex.

AIM:As a factor that can improve cell growth,there are few studies about the effect of insulin-like growth factor Ⅰ(IGF-Ⅰ) on the apoptosis of endothelial cell.The study investigated the inhibition and mechanism of IGF-Ⅰ on the apoptosis of human umbilical vein endothelial cells(HUVEC) induced by oxidized low density lipoprotein(ox-LDL).METHODS:The experiment was performed in the Institute of Cardiovascular Disease,Union Hospital of Huazhong University of Science and Technology from December 2006 to July 2007.①Fresh human umbilical cord was obtained(the informed consent) to isolate and culture HUVECs.The cells were divided into four groups.Except the control group,HUVEC cells were cultured with IGF-Ⅰ(1?10-9mmol/L),ox-LDL(200 mg/L)+IGF-Ⅰ(1?10-9mmol/L),and ox-LDL(200 mg/L),respectively after cultured for 24 hours.②Cell viability was determined by MTT assay,morphology and apoptosis by DAPI fluorescence staining,and expressions of caspase-3 were analyzed.RESULTS:①Ox-LDL could significantly inhibit HUVEC cell proliferation.After treated with both IGF-Ⅰand ox-LDL,the cell proliferation increased obviously compared with the cells treated with ox-LDL(P

Objective To analyze the onset time rule of spontaneous pneumothorax ,and investigate the influence of climatic factors such as atmo-spheric pressure,wind speed,etc. on the onset of spontaneous pneumothorax. Methods Five hundred and ninety-three patients of spontaneous pneumothorax in Cenral Hospital Affiliated to Shenyang Medical College were enrolled for this study between January 1,2011 and December 31, 2015. The data of the average daily atmosphere pressure and wind speed in five years were recorded. The relationship between the onset of sponta-neous pneumothorax and the change of the atmosphere pressure and wind speed was analyzed. Results The incidence of spontaneous pneumotho-rax in Shenyang area was obvious seasonal. Primary spontaneous pneumothorax episodes were observed mostly in spring and in March and April;Second spontaneous pneumothorax episodes were observed mostly in winter and in November and December. The difference in mean atmospheric pressure was 0.6 hPa lower than on days in which no spontaneous pneumothorax occurred. This difference was statistically significant(P=0.015). We observed significantly higher average wind speed on days with SP versus days without(9.46±6.33 m/s vs 7.11±5.47 m/s,P<0.001). Conclu-sion Spontaneous pneumothorax has obvious aggregation of onset time. A sharp drop in atmospheric pressure and increases in wind speed has im-portant influence on the incidence of spontaneous pneumothorax.

Objective To compare and analyze the performance indexes and the imaging quality of the home and imported X-ray machines through testing their partial imaging performance parameters. Methods By separate sampling from 10 home and 10 imported X-ray machines, the parameters including tube current, time of exposure, machine total exposure, and repeatability were tested, and the imaging performance was evaluated according to the national standard. Results All the performance indexes met the standard of GB4505-84. The first sampling tests showed the maximum changing coefficient of imaging performance repeatability of the home X-ray machines was ?max1=0.025,while that of the imported X-ray machine was ?max1=0.016. In the second sampling tests, the maximum changing coefficients of the two were ?max2=0.048 and ?max2=0.022, respectively. Conclusion The 2 years′ follow-up tests indicate that there is no significant difference between the above-mentioned parameters of the elaborately adjusted home X-ray machines and imported ones, but the home X-ray machines are no better than the imported X-ray machines in stability and consistency.
