RESUMO
By monitoring the effluent quality from different green roof assemblies during several artificial rain events, the main pollutant characteristics and the influence of substrate composition in extensive green roof on the effluent quality were studied. Results showed that the main pollutants in the effluent were N, P and COD; with the increase of cumulative rain, the concentrations of pollutants in the effluent decreased, which had obvious leaching effect; The average concentrations of heavy metals in the early effluent from all assemblies reached drinking water standard, including the assemblies using crushed bricks; When garden soil and compost were used as organic matter, the assemblies had serious leaching of nutrient substance. After the accumulated rainfall reached 150 mm, the TN, TP and COD concentrations of effluent were 2.93, 0.73 and 78 mg x L(-1), respectively, which exceeded the Surface water V class limit. By means of application of the Water Treatment Residual, the leaching of TP from green planting soil was decreased by about 60%. The inorganic compound soil had better effluent quality, however we also need to judge whether the substrate could be applied in extensive green roof or not, by analyzing its ability of water quantity reduction and the plant growth situation.

OBJECTIVE: To compare the therapeutic effects of triple puncture at Tianzong (SI 11) and routine acupuncture on obstinate tennis elbow. METHODS: Sixty-two cases were randomly divided into 2 groups. The treatment group of 32 cases were treated with triple puncture at Tianzong (SI 11) combined with local points of the elbow, and the control group of 30 cases were treated with local points of the elbow. After one therapeutic course, changes of the symptoms and signs between the two groups were compared. RESULTS: The cured rate of 71.900 in the treatment group was significantly better than 43.3% in the control group (P < 0.05). CONCLUSION: Triple puncture combined with routine acupoint selection therapy has a better therapeutic effect on obstinate tennis elbow than the routine acopoint selection therapy.
