Litchi chinensis

The Ranunculaceae, or buttercup family, is a large group of dicotyledonous plants within the Magnolia subclass. Most members are herbs, with few being small shrubs or woody vines. A distinguishing feature is that the main roots often wither early, and fine, hair-like adventitious roots emerge from the base of the stem. Leaves are typically simple or compound, arranged alternately or basally, and may be opposite in some species. The venation is usually palmate or pinnate. Inflorescences vary, including cymes, cymules, and racemes, with flowers often showing radial or irregular symmetry. Sepals can be green or petal-like, and petals may be absent or present in various colors. Some species have specialized structures for attracting pollinators. Stamens are spirally arranged, numerous, and vary in number. Anthers may appear at the base of filaments, and pollen grains often have three furrows, though some species show different patterns. Chromosome numbers commonly include x=6, 7, 8, 9, and 12. This family comprises about 60 genera and 2,200 species, found worldwide, with the majority in the northern temperate zone. China alone has 39 genera and around 720 species, mainly concentrated in the mountainous regions of the southwest. Five endemic genera include Thalictrum, Cimicifuga, Aconitum, Ranunculus, and Pulsatilla. Flowers typically open with stamens first, and many species have evolved unique petal forms to attract insects. In species like Clematis and Thalictrum, pollination often relies on pollen-feeding insects. Some evolutionary forms, such as those in the genus Thalassia, may adapt to wind pollination. The achenes of Pulsatilla and Clematis have feathery styles that help with wind dispersal. Others, like certain species of Anemone and Thalassia, have hooked styles or spiny achenes for animal dispersal. Seeds in Cimicifuga and Aconitum have membranous wings, also aiding wind transport. Ranunculaceae plants contain a wide range of chemical compounds. Over 220 species in China are used medicinally, including well-known herbs like Huanglian (Coptis), Aconite, Cimicifuga, and Chuanmutong. Trollius flowers contain anti-inflammatory compounds, while Cimicifuga has tetracyclic triterpenes and furanones that reduce fever and detoxify. Aconitum and Delphinium contain toxic diterpenoid alkaloids with medicinal uses, such as aconitine for local anesthesia. Thalictrum contains benzylisoquinoline alkaloids with antibacterial properties. Berberine in Coptis has antibacterial, anti-inflammatory, and vasodilatory effects. Pulsatilla and Anemone contain ranunculin, which becomes protoanemonin after hydrolysisâ€”strong against bacteria. Clematis contains glycosides and saponins, and some species are used for rheumatism. Ranunculus has glycosides useful in topical treatments, and some species help treat lymphatic tuberculosis. As one of the earliest angiosperm families, Ranunculaceae exhibits characteristics similar to Magnoliaceae, such as spiral stamen arrangement and abundant endosperm. However, most members are herbaceous, lack stipules, and have multiple pollen germination pores. Based on morphology, chromosome numbers, and fruit types, the family is divided into three subfamilies: Helleboroideae, Thalictroideae, and Ranunculoideae. Representative genera include Aconitum, with over 350 species, especially in Asia. Aconitum species are known for their helmet-shaped sepals and medicinal value. Delphinium, with over 300 species, is similar but lacks petal claws. Thalictrum, with about 200 species, includes ornamental varieties like T. arundinaceum. The monotypic genus Kingdonia is rare, found in high-altitude regions of China, with unique leaf venation resembling gymnosperms, leading some to propose it as a separate family, Kingdoniaceae. Overall, the Ranunculaceae family is diverse, ecologically significant, and holds great importance in both medicine and horticulture. Its rich diversity and unique adaptations make it a fascinating subject for botanical study.

China Telecom's Global Eye and the former China Netcom have developed remote video monitoring in conditional households. For example, the wide view video monitoring business has been launched in China Netcom's Shanxi, Shandong, Jilin, Zhejiang, Henan and other provincial companies in the early stage, and has been widely welcomed by customers. The wide view business has developed rapidly. In the first half of this year, only Hubei Netcom's "wide view - God's Eye" business has developed more than 500 households. With the rapid development of family information technology, users' demand for family security is becoming stronger and stronger, and the broad horizon will maintain rapid development. China Mobile is also developing mobile MMS monitoring represented by "Handyantong", and 3G video monitoring is also being tested and commercially tested. It is difficult to develop and promote home video surveillance because of the huge data and signal flow relying on the network and the need to deploy home gateways and cameras.

Video monitoring is mainly used in the communities closely connected with families in the industry field, but it is still less used for home monitoring. Under the guidance of the policy of safe cities and safe families, the domestic family monitoring will begin to rise with the continuous improvement of family network environment, the improvement of users' consumption ability, the growth of security awareness, and the increase of independent living families. The integrated video monitoring that integrates limited, wireless access and linkage alarm will become a development trend. Full service operation has arrived. Operators will certainly provide users with wired and wireless diversified technical monitoring means. Through business integration, they will bring users endless monitoring services. Monitoring realizes the discovery and prevention of family safety, and also reflects family care. In addition, efforts should be made to solve the problem of security. Therefore, family monitoring needs to gradually increase some new functions and applications such as linkage alarm and security services, such as emergency help, interaction with public security, medical care, housekeeping, and calling.
