Objective Inhibition of matrix seedling raising in winter greenhouse on premature bolting of Angelica sinensis.Methods Three factors of sowing periods,soil media,and seeds were tested in ortho-gonal design by repeated three times.Results In total 15 treatments,bolting percentage of A.sinensis in seven treatments were lower than 1%,among which the lowest was 0.14%;In the other seven treatments,the bolting percentages were 1%—5%,and in another treatment,it was 19.93%.No bolting happened in 40% of total 45 tested plots,and the bolting percentage was lower than 5% in other 46.7% tested plots.Stalk of winter raised seedlings started to produce at the beginning of August,which delayed 70 d compared to that of the traditional seedlings,bolting peak period of winter raised seedlings was in the middle of September,which delayed 100 d compared to that of the traditional seedlings.In total 15 treatments,100% of bolting plants only stalked,but no flowers produced in six treatments,over 50% of bolting plants only stalked,but no flowers produced in the other eight treatments,38.9% of bolting plants only stalked but no flowers produced in another one treatment.The sample test showed that ethanol extracts content of bolting plant root without flower was 45.93%.Influence in each one of these three factors to premature bolting percentage approached to the utmost notable difference,the influence sequence was sowing periods,seeds,and soil matrixes.Conclusion Premature bolting percentage of A.sinensis is not only obviously decreased by matrix seedling raising in winter greenhouse,but also the bolting can possibly be avoided,and bolting date be also delayed greatly.

OBJECTIVETo study the inhibition effect of winter seedling raising in sunlight-greenhouse on premature bolting of Angelica sinensis.

METHODOne factor of sowing date with 4 levels was tested at random design with 3 repeats.

RESULTSowing date of winter seedling raising had an important effect on seedling growth, seedling mature, plant growth, premature bolting, yield, quality, and extreme significant effect on yield. The bolting date of winter raised seedlings started in middle of July, 50 d later than tranditional seedlings, and bolting peck date was in the last ten days of July, 40 d later than the traditional seedlings. The highest ratio of premature bolting for winter raised seedlings was 1%, and the lowest was 0. A. sinensis roots sowed in November 28 had the highest yield, root dry ratio, ethanol extract, essential oil and ferulic acid contents compared to that in other sowing dates. The best sowing time was from end of November to middle of December.

CONCLUSIONPremature bolting of A. sinensis could be greatly inhibited by winter seedling raising, end of November to middle of December would be the best sowing time for winter seedling raising in greenhouse.

In this paper a new super-resolution image reconstruction algorithm was proposed. With the improvement of the classical projection onto convex sets (POCS) algorithm, as ground work, and with the combined use of POCS and wavelet fusion, a high resolution CT image was restored by using a group of low resolution CT images. The experimental results showed: the proposed algorithm improves the ability of fusing different information, the detail of the image is more prominent, and the image quality is better.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.
