Objective To make a textual researchhttp://172.24.132.63/toc/Master/Analyze.aspx#Illustrations on Zisu about the name, origin, morphology and efficacy, a dualpurpose medicinal and edible plant, in order to make the original clear and provide reference basis for clinical application. Methods Textual research was carried out from the aspects of synonym, distribution, morphology, efficacy, toxicity and side effects of the plants. Results Zisu，Baisu and Su in the herbal medicine of past dynasties belong to the Ren category, which are species or varieties of Perilla frutescens（L.）Britt. Zisu has purple leaves, and its stems, leaves and seeds are used as medicine to mainly lower Qi. While Baisu has green leaves, which could cure wind cold. Conclusion There are significant differences in botanical morphology and pharmacological efficacy between Zisu and Baisu, which should be distinguished and used separately. Zisu is a dual-purpose traditional Chinese medicine with a long application history. Baisu is not suitable for edible consumption. [ABSTRACT FROM AUTHOR]

Objective To observe changes of choroidal thickness in patients with primary grade 3 hypertension and analyze its related influencing factors. Methods Twenty eight patients (56 eyes) with primary grade 3 hypertension were selected as the hypertension group, and 29 healthy volunteers (58 eyes) with normal fundus were selected as the normal group. The choroidal thickness in macular region was measured by optical coherence tomography enhanced deep imaging in patients of the two groups. The choroidal thickness in different macular regions was observed in the two groups, and the retinal thickness in each macular region of the two groups was compared. The correlation between choroidal thickness and retinal thickness and course of disease in patients with hypertension was analyzed. Simple linear regression was used to analyze the effect of age on choroidal thickness. Results The choroidal thickness in N6 zone of macula was significantly lower than that in other areas in two groups (P＜0.05). The choroidal thickness in central area, S3, T3, I3, S6, T6 and I6 was significantly lower in the hypertensive group than that in the normal group (P＜0.05). Compared with the normal group, the retinal thickness in I6 and N6 area was decreased in the hypertensive group (P＜0.05). There was a positive correlation between choroidal thickness and retinal thickness in S3 and S6 zones of the hypertension group (P＜0.05). There was no correlation between the duration of hypertension and the thickness of choroid in each area of macula (P＞0.05). There was no correlation between patient age and thickness of choroid in N3 zone in the hypertension group (P＞0.05), but there was weak correlation with the thickness of choroid in central, S3, I6 and N6 zone (adjusted R2 ＜0.100, P＜0.05). It was negatively correlated with thickness of choroid in the T3, I3, S6 and T6 zones (adjusted R2 : 0.118, 0.114, 0.102 and 0.155, P＜0.05). Conclusion The thickness of choroid in macular area is lower in patients with primary grade 3 hypertension than that in normal population. Changes of choroid thickness is correlated with retinal thickness and age, and no correlation with disease duration. [ABSTRACT FROM AUTHOR]

Objective To investigate the current status of breastfeeding in children under one year old in Baizhifang community of Beijing City, and to explore its influencing factors in order to provide a basis for promoting breastfeeding in children. Methods The cross sectional study was adopted from August 2017 to January 2018. Totally 222 infantile mothers were selected as the study subjects in the plan immunization clinic by using the convenient sampling method and conducted the questionnaire investigation. Results Among 222 infants, 136 cases were 0-6 months old, the exclusive breastfeeding rate was 61. 76% (84/136) ; the continuous breastfeeding rate in the infants under 1 year old had no statistical difference among the mothers with different ages, different education backgrounds, and delivery modes(P >O. 05) ;there was no statistically significant difference in breastfeed ingrate between the floating population and native population(P >O. 05). Only 69. 49% (123/177) of the mothers could feel that the nannies and the babysitters thought that breast milk was better than the formula milk powder. 77. 93% (173/222) of the community health service centers in infantile mothers location provided post natal visits and other services. Only 23. 98% ( 4 7 /196) of the work units set up a dedicated breastfeeding room. Conclusion The exclusive breastfeeding rate of infants and young children with 6 months old in the Baizhifang community of Beijing City still needs to be improved. The family support, health service status and social environment of continuing breastfeeding in children under one year old still need to pay more attention. [ABSTRACT FROM AUTHOR]

This article reviews the research on the effects of symbiotic fungi on plant drought resistance. Symbiotic fungi are widely distributed,which can form symbionts with plants. Studies have shown that some endophyte and symbiotic fungi can enhance plant's biological and non-biological stress tolerance,including drought, high temperature,mineral disorder and high salt. The plants infected by symbiotic fungi are more competitive than uninfected plants to the limited resources and grow better. Symbiotic fungi can enhance the resistance tolerance of plants through diverse channels. The mechanisms of improving the drought resistance mainly related to the absorption of nutrients,plants protection systems, hormonal regulations,hydrolytic enzymes,water metabolisms,related gene expressions,plants defense signal pathways,etc. This paper summarized the mechanism research progress of symbiotic fungi on improving plant drought resistance,which gave readers a comprehensive and updated information in this field.

[Objectives] With the shortage of picking labor and the rising price of picking cotton,the mechanical harvesting of cotton has become the main way of harvesting cotton. It is necessary to study the effects of planting density and nitrogen application rate on cotton growth characteristics and yield under the machine harvested cotton planting mode.[Methods]The variety was ‘Xinluzhong 54’. The design was the split zone test:2 planting densities in the main area(180,240 thousand plants·hm-2),and 4 nitrogen application rates(0,170,320,470 kg·hhm-2)in the sub area.[Results]When the planting density was 240 thousand plants·hhm-2 and the nitrogen application rate was 320 kg·hhm-2,the yield and nitrogen agronomic efficiency were the highest,respectively 33.64% and 6.38 kg·kg-1. The difference was not significant with the highest yield. Under the same planting density,plant height,3rd leaf width,the number of true leaf,the number of fruit branch,stem diameter,the daily growth of the main stem and the accumulation of dry matter in the population increased with the increase of nitrogen application. Under the same nitrogen application rate,with the increase of planting density,the above traits decreased. Increasing nitrogen fertilizer and increasing planting density will prolong the growth period. When planting density was 180 thousand plants·hhm-2,leaf area index,boll number per plant,quality of single boll,lint percentage and seed cotton yield increased with the increase of nitrogen application rate. When the planting density was 240 thousand plants·hhm-2,the above traits increased first and then decreased. There was a positive correlation between agronomic traits and yield components. The increase rate and nitrogen agronomic efficiency increased first and then decreased with the increase of nitrogen application rate. The increase rate and nitrogen use efficiency increased with the increase of planting density.[Conclusions]When the density of cotton planting in southern Akesu was 240 thousand plants·hhm-2,and nitrogen application rate was 320 kg·hhm-2,the yield and nitrogen agronomic efficiency were the highest and the yield was higher. The agronomic characters conform to the standard of mechanical mining. [ABSTRACT FROM AUTHOR]
