Changes in the vascular cylinder of wild soybean （Glycine soja Sieb. et Zucc） roots under alkaline stress were investigated in an experiment that applied 90 mmol L1 alkaline stress for 10 d at the five-trifoliate plant growth stage in Huinan County, Jilin Province, China. Root samples were collected and paraffin-cut sections were made, and the root structure was observed under an optical microscope. There were significant changes in the vascular cylinder of G. soja roots under alkaline stress. Root diameter was reduced and the vascular cylinder changed from tetrarch to triarch pattern. Alkaline stress resulted in reduced, diameters of root vessels, and a large amount of residual, alkaline solution was stained cyaneous in vessels. The paratracheal parenchymatous cells of the vessels were large and there was little secondary xylem. Thus, alkaline stress caused structural changes in the vascular cylinder of G. soja.

在昆山市巴城镇武神潭村设立观测试验点,对水温、溶解氧、pH、氨氮及大闸蟹生长动态情况进行监测,讨论适宜大闸蟹生长的水质环境。结果表明,水温对于大闸蟹的影响最大,温度突然变化或者超过30℃易造成大闸蟹的死亡;溶解氧白天呈单峰型,藻类对于溶解氧贡献最大;7月中旬后pH逐步下降且趋于平稳,氨氮总体较低,利于大闸蟹生长。水温28℃左右、溶解氧维持4 mg/L以上、pH 7.5~8.5是阳澄湖大闸蟹适宜生长的水质环境。

Objective: To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional(3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer(IVF-ET). Methods: Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days(from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji(CV3), Qihai(CV 6), Sanyinjiao(SP6), Taichong(LR 3), Tianshu(ST 25), Guilai(ST 29) and Zusanli(ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index(VI), flow index(FI) and vascularization flow index(VFI), endometrial thickness and volume, subendometrial VI(sVI), subendometrial FI(sFI), subendometrial VFI(sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births. Results: Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group(P0.05). Conclusions: Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometr
