Archaeocalamites scrobiculatus （Brongniart） Stur; bowmanitid Sphenophyllum tenerrimum （Ettingshausen） Stur; pteridophyll Sphenopteris sp. of uncertain taxonomic position; undetermined ferns gen. et sp. nov.; lyginopterid pteridosperm Rhodeopteridium hsianghsiangense （Sze） Zhang, Zhao et Wu, a trigonocarpoid pteridosperm represented by fronds and isolated pinnules of Paripteris gigantea （Sternberg） Gothan, male fructifications of Potoniea sp., and seeds of Trigonocarpus sp. Ecologically, the Early Carboniferous （Visean） Huadu vegetation was divided into two neighboring communities： （1） a near-shore hydrophilous ＂community A＂ with predominating Archaeocalamites and Rhodeopteridium; and （2） a wet forest ＂community B＂ with predominating shrubby trigonocarpalean pteridosperm Paripteris gigantea （Sternberg） Gothan and tall tree-like lepidodendrid Lepidodendron shanyangense Wu et He. The Huadu vegetation was physiognomically similar to present-day low-latitude mangrove forest.展开更多

[Methods]Real-time RT-PCR and CPE methods were used to observe the inhibition of Zijin Huadu suppository on virus,and turbidimetry was used to observe bacteriostatic action; HE pathological section was used to observe cervicitis of rat,and enzyme-linked immunosorbent assay was used to detect virus' s expression in cervical tissue.[Results]In cervicitis rat model infected by HPV16,Zijin Huadu suppositories at the doses of 1. 2,0. 6 and0. 3 g/( kg·d) had significant inhibitory effect on HPV16 expression in cervical tissues,and the doses of 1. 2 and 0. 6 g/( kg·d) had significantly inhibitory effect on pathological changes of cervical tissues. In cervicities rat models infected mixedly by Escherichia coli,Neisseria gonorrhoeae and Staphylococcus aureus,Zijin Huadu suppositories at the doses of 1. 2 and 0. 6 g/( kg·d) had significant inhibitory effect on pathological changes of cervical tissues. In cervicitis rat models induced by chemical substances,Zijin Huadu suppositories at the dose of1. 2 g/( kg·d) had significant inhibitory effect on vagina and cervix lesions in rats. In vitro,Zijin Huadu suppository showed obvious inhibitory effects on HSV-2,HPV16,Staphylococcus aureus,Staphylococcus albus,Staphylococcus epidermidis,group B Streptococcus,E. coli,Pseudomonas aeruginosa,Proteusbacillus vulgaris,Neisseria gonorrhoeae and Candida albicans.[Conclusions] Zijin Huadu suppository has obvious inhibitory effect in vitro on viruses and bacteria,and could obviously improve the phenol-induced cervicitis.展开更多

Taking Huadu District in Guangzhou City for example, urban green landscape pattern was analyzed from the level of region and district, according to the landscape ecology. The results showed that local green landscapes had many problems such as unreasonable structure, high fragmentation, unbalanced distribution of green space types, poor corridor networks etc.. In view of these problems, countermeasures for improving green landscape images in Huadu District were proposed.展开更多
