The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.

Objective: To understand the suicidal ideation among migrant construction male workers in Pudong New Area, Shanghai, and analyze the influence factors based on social cognitive theory. Methods: Surveys were carried out among 1 850 migrant construction male workers from 3 randomly chosen construction sites using cluster random sampling. Univariate and multivariate Logistic regressions analysis were used to explore the association between suicidal ideation and its related factors such as negative psychology, negative cognition and high-risk behavior. Results: Among the total 1 580 respondents completed the survey, 126 (8.0%) reported having suicidal ideation. In the univariate Logistic regression analysis, drug abuse, alcohol abuse, depression, generalized anxiety and loneliness were risk factors for suicidal ideation, while perceived social support was a protective factor. Five of the six variables, alcohol abuse (ORm=2.15, 95%CI 1.42-3.24), depression (ORm=2.47, 95%CI 1.17-5.21), generalized anxiety (ORm=2.24, 95%CI 1.50- 3.35), loneliness (ORm=2.09, 95%CI 1.28-3.40) and perceived social support (ORm=1.84, 95%CI 1.20-2.83) were selected by the multivariate Logistic regression analysis. Conclusion: Suicidal ideation among migrant construction male workers in Pudong New Area, Shanghai occurs under the influence of negative psychology, negative cognition and high-risk behavior. For the crowds, family and society should be actively promoted and mental health interventions should be strengthened, which could effectively prevent suicide ideation.

Objective To study feasibility of combined haemostatic percutaneous injection therapy guided by contrast-enhanced ultrasonography (CEUS) in treatment of renal injuries. Methods Eighteen New Zealand rabbits were inflicted with kidney injury imitating grades Ⅲ-Ⅳ blunt injuries. The animals were randomly and equally divided into three groups, Group A ( treated with hemocoagulase),Group B ( treated with hemocoagulase and Alpha-cyanoacrylate) and Group C ( control group, given normal saline). The hemostatic time, hemostatic effect, and perirenal hematoma were observed. Results A perirenal hematoma was observed one hour after treatment. The perirenal fluid thickness was (0.200 ±0.012) cm in Group A, (0.050 ±0.002) cm in Group B and (0.400 ±0.009) cm in Group C, with statistical significance between two test groups and Group C (P ＜ 0.05 ). At days 7 and 14 following treatment, lesion length and cross section was ( 1. 107 ±0. 143) cm and (0.433 ±0. 163) cm in Group A, (0.567 ±0.082) cm and (0. 160 ±0. 078) cm in Group B, and (0.980 ±0. 203) cm and (0.686 ± 0. 157) cm in Group C. There was statistical significance between the test groups (Groups A and B) and Group C (P＜0. 01) at day 14. The lesion size in Group A was lager than that in Group B (P ＜ 0.01 ). One month after treatment, a slight nephrohydrosis occurred in Group B. Conclusions Either injection of simple hemocoagulase or combined use of hemocoagulase and Alpha-cyanoacrylate guided by CEUS can attain positive hemostatic effect, but the latter one is more rapid and reliable.
