However,few studies have addressed the mechanism by which elevated CO_2 may affect the growth of medicinal plants. Isatis indigotica Fortune is a widely used Chinese medicinal herb with multiple pharmacological properties. To investigate the physiological mechanism of I.indigotica response to elevated [CO_2], plants were grown at either ambient [CO_2](385 μmol mol^(-1)) or elevated [CO_2] (590 μmol mol^(-1)) in an open-top chamber (OTC)experimental facility in North China. A significant reduction in transpiration rate (T_r) and stomatal conductance (g_s) and a large increase in water-use efficiency contributed to an increase in net photosynthetic rate (Pn) under elevated [CO_2] 76 days after sowing. Leaf non-photochemical quenching (NPQ) was decreased, so that more energy was used in effective quantum yield of PSII photochemistry (Φ_(PSⅡ)) under elevated [CO_2]. High ΦPSII,meaning high electron transfer efficiency, also increased Pn. The [CO_2]-induced increase in photosynthesis significantly increased biomass by 36.8%. Amounts of metabolic compounds involved in sucrose metabolism, pyrimidine metabolism, flavonoid biosynthesis, and other processes in leaves were reduced under elevated [CO_2]. These results showed that the fertilization effect of elevated [CO_2] is conducive to increasing dry weight but not secondary metabolism in I. indigotica. 展开更多

The relation between human and crop resources belongs to the ethic of resources exploitation. The purposes of discussing the ethic of crop resources are to protect the ecology and safety of crops, to gain sustainable development, furthermore, to choose and form the production structure that is favorable to saving crop resources and protecting the ecology of crops. Plant genetic engineering is the technology of molecule breeding of rearrangement of inheritance materials at the level of molecule directionally, of improving plant properties and of breeding high quality and yield varieties of crops. The prominent effects of the technology on the crop ecological system are human subjective factors increasing as well as violating the nature and intensifying the conflict between human being and nature. Therefore, in plant genetic engineering, crop resources exploitation should follow certain ethic principles. Under the theory of ethics of natural resources, by the means of biologinal-statistics, the author systematically analyzed the possible model of crop resources transfer between generations as well as the transfer mode of magnitude of real materials and magnitude of value. 展开更多

Integrative medicine follows the principles in TCM that nature and human beings being correspondent with its holistic and dialectic views and explores the integrating point with theories and scientific data in modern medicine. During study on 16 gynecological diseases, the deficiency. In patients with pubertal uterine bleeding, ovulation is induced by acupuncture via decrease in central β-endorphin (β-EP) levels, which leads to the cure of anorexia nervosa by acupuncture via decrease in serum cortisol levels in early 1980s. These results in TCM lead to the idea that neuro-endocrine system is directly related to metabolic system which is also proved to be true in the treatment of polycystic ovary syndrome (PCOS) with or without hyperinsulinemia by two formulas (Yu's Tonifying Ricipe and Tian Gui Recipe,TGR) respectively according to differential diagnosis in TCM. Ovulation resulted with decrease in obesity, acanthosis nigricans, serum androgen, insulin, leptin and hyperthalamic neuropeptide Y (NPY), proopiomalanocortin (POMC) levels based on scientific data from both patients and an animal modal. It suggests that metabolic network, and the incidence of obesity, hypertension, diabetes and cancers of the endometrium and breast may be reduced among patients with PCOS in their future life while these recipes being taken long period. For perimenopausal syndrome, formula Geng Nian Chun (GNC)without increase in serum estrogen levels. In aging rats, it was found that GNC increased the ER and ERmRNA expressions in the ovarian axis and the spleen accompanying with increase in central β-EP, serotonin (5-HT) and peripheral interlutin-2 (IL-2) levels in aging rats without changes of estrogen levels. These data may refer to the release of symptoms in women with postmenopausal syndome. It suggests that GNC up-regulates the fading of neuro-endocrine-immune network. Prevention, alleviation of osteoporosis, cardiovascular disease and Alzheimer disease may be expected in aging women with long period taking GNC. 展开更多

She writes plenty of poems with unique perspectives, bold and innovative themes and various writing techniques. And her poetry possesses incomparable originality. Her close attention is often devoted to those seemingly trifling and subtle things. This paper is to explore her four poems which manifest she is always morally pure and indifferent to fame and fortune. It can be seen that self-cultivation is far more significant than physical achievement. 展开更多

The liberation of women is the historical process in which women have striven for gender equality, freedom from oppression, confinement and discrimination, and are becoming the masters of the society and their own destinies. According to the diversity in history and the state, the process can be divided into a serial of correlated phases, with each phase focusing on different issues. Sexism order in China had remained stable in the traditional society for centuries through a set of institutions. Women had believed in a sexual order and the rules of propriety, which advocated that men were superior to women. After the People’s Republic of China was founded in 1949, women’s rights in politics, economy, society, and even family were recognized and secured by the Constitution and laws just as men’s during a short period. Women’s liberation in China has made a significant progress. 展开更多
