Objective To observe the effects ofTanyu Tongzhi Formula on proliferation and migration of human umbilical vein endothelial cells (HUVECs);To explore its activity of pro-angiogenesis.Methods HUVECs were cultured in vitro. Rats were treated with gavage containing different doses ofTanyu Tongzhi Formula (78.0, 39.0, 19.5 g/kg) to prepare serum with different doses of medicine. The activity of HUVECs was measured by MTT method. The effects on migration of HUVECs were inspected by using scratch wound assay.Results Compared with the normal control group, serum containing high-dose and medium-doseTanyu Tongzhi Formula could significantly promote the proliferation of the HUVECs (P<0.01). The rates were 49.78% and 33.92% respectively. And the cell migration rate was higher in the two groups than in the normal control group (P<0.01). The rates were 11.36% and 11.62% respectively.ConclusionTanyu Tongzhi Formula can promote proliferation and migration in HUVEC, which may be active to pro-angiogenesis.

Object To determine the histochemical location d eposited artemisinin and to provide selection character for screening of Artemisia annua L. which contains rich content of artemisinin Methods Artemisinin was located by the histochemic al method and then statistical method was used to ascertain the correlation betw een the content of artemisinin and the density of biseriate glandular triche mes (BGT) Results Artemisinin is located in both BGT and non glandular T -shaped filamentous trichomes (NTFT) in A annua leave s The content of artemisinin had a positive correlation with the density of BG T in A annua leaves Conclusion High density of BGT in foliar tissue might be considered as one of the selection characters for the screening of A. annua with rich content of artemisinin

In order to improve the effect of teaching and teachers' ability,make our teaching methods adapt to the social development,the department of Endocrinology used the method of preparing lessons collectively in our teaching.We found that the method not only made the the supply of teachers reasonably but also made good contribution to the students' culture.Practice testified that the method of preparing lessons collectively could adapt to the new model of cultivation and create substantial results.

BACKGROUND: At present, more and more scholars pay attention to the influence of spine and pelvis sagittal balance on the quality of life of patients. Postoperative changes in spine imaging parameters fol owing corrective osteotomy for lumbar degenerative kyphosis have not been reported. OBJECTIVE: To evaluate postoperative changes in sagittal balance fol owing corrective osteotomy for lumbar degenerative kyphosis. METHODS: We retrospectively analyzed 35 consecutive lumbar degenerative kyphosis patients treated with posterior osteotomy fixation in the First Affiliated Hospital of Xinjiang Medical University from February 2012 to December 2014. Imaging parameters were measured before fixation, immediately after fixation and during final fol ow-up. RESULTS AND CONCLUSION: (1) There were significant differences between preoperative and postoperative parameters except for pelvic incidence angle (P < 0.05). (2) There were significant differences between postoperative and last fol ow-up parameters except for Cobb angle, pelvic incidence angle, thoracic kyphosis angle and the thoracolumbar kyphosis (P < 0.05). (3) Pelvic tilt angle was negatively correlated with lumbar lordosis after fixation (r=-0.610, P < 0.001). Thoracic kyphosis was positively correlated with lumbar lordosis (r=0.598, P < 0.001). (4) Results suggested that lumbar sagittal contour can be significantly improved by corrective osteotomy for lumbar degenerative kyphosis. Simultaneously, reciprocal changes in the adjacent areas such as thoracic spine and pelvis occur to adapt to the new sagittal balance.

Objective To investigate the characteristics of frequently cited papers in Chinese Journal of Nuclear Medicine and Molecular Imaging (CJNMMI) during year 1998-2013.Methods Based on Wan Fang database,the citation number of each paper published in CJNMMI during year 1998-2013 was recorded.Percentage method was used to determine the number of frequently cited paper.The published year,regional distribution,number of authors,columns,key words and funding of the frequently cited paper were analyzed.Results There was 5.43％ (140/2 580) of the papers published in CJNMMI from year 1998-2013 were considered frequently cited.These 140 frequently cited papers accounted for 37.49％ (2 533/6 757) of the total number of citations,with an average citation number of 18.09.A total of 77.86％ (109/140) of these frequently cited papers were published during year 2000-2005,and 65.00％ (91/140)of them had 3-6 authors.Seven authors published 3 or more of these frequently cited papers.Most papers were from Beijing,Guangdong and Shanghai.The top 3 columns with frequently cited papers were nuclear oncology,endocrinology and neurology (16.43％,10.00％,9.29％).Conclusion Analysis of the frequently cited papers in CJNMMI with regard to characteristics,such as published year,research field and district distribution,may provide useful reference for topic selection in the future.

In this paper, the morphological development of periderm of the hands and feet of 21 human embryos were investigated. The estimated gestational age (EGA) of the collected specimens were 6-24 weeks.On 36th to 41st days of EGA, the cells of embryonic periderm were seen to be flat and polygonal in shape. Microvilli were seen on the cell surface. At the end of 7th week the cells showed conspicuous central elevations as cobblestones. After 11th week, a large single bleb occurring on the cell surface were observed. At 4th month, the number of the blebs increased and complex blebs were formed. Larger blebs showed infoldings and furrows. Then the blebs disappeared and the cell surface became flat again. The cells of periderm began to shed at 17th week.The development of periderm on the hands appeared earlier than that on the feet. The degree of the development of periderm in different regions of hands and feet may be different. The possible significance of the periderm was discussed.
