AIm: To evaluate the results of the treatment of simple liver cysts (solitary and multiple) and polycystic liver disease (PLD) using percutaneous sclerotherapy and/or surgical procedures in a single tertiary referral centre. mETHODS: Retrospective analysis of 54 patients referred for evaluation and possible treatment of simple liver cysts (solitary and multiple) and PLD, from January 1997 to July 2006. RESULTS: Simple liver cysts were treated in 41 pts (76/) with a mean size of 12.6 cm. The most common reason for referral was abdominal pain or discomfort (85/). Percutaneous sclerotherapy was performed as initial treatment in 30 pts, showing cyst recurrence in 6 pts (20/). Surgical treatment was initially performed in 11 pts with cyst recurrence in 3 pts (27/). PLD was treated in 13 pts (24/) with a mean size of the dominant cyst of 13 cm. Percutaneous sclerotherapy for PLD was performed in 9 pts with recurrence in 7 pts (77.8/). Surgical treatment for PLD was undertaken in 4 pts (30.8/) with recurrence in all. Eventually, 2 pts with PLD in the presence of polycystic kidney disease underwent liver-and kidney transplantation because of deterioration of liver and kidney function. CONCLUSION: The majority of patients with simple liver cysts and PLD are referred for progressive abdominal pain. As initial treatment, percutaneous sclerotherapy is appropriate. Surgical deroofing is indicated in caseof cyst recurrence after percutaneous sclerotherapy. However, the results of percutaneous sclerotherapy and surgical treatment for PLD are disappointing. Partial liver resection is indicated when there is suspicion of a pre-malignant lesion.

【目的】通过测定不同施肥制度下的微生物数量和氨氧化细菌群落结构特点,认识长期施肥对石灰性紫色水稻土培肥和肥力演化的重要作用。【方法】利用稀释平板法以及最大或然法(mPN法)和变性梯度凝胶电泳法(DGGE)分别研究农家肥(m),氮肥+农家肥(Nm),氮磷肥+农家肥(NPm),氮磷钾肥+农家肥(NPKm),无肥(CK),氮肥(N),氮磷肥(NP)和氮磷钾肥(NPK)等不同施肥制度对微生物数量和氨氧化细菌群落结构的影响。【结果】与对照无肥处理相比,施肥能增加微生物数量并改变氨氧化细菌的群落结构。无机肥配施农家肥的土壤微生物数量及氨氧化细菌的群落结构丰富度均比施用无机肥的处理高。主成分分析将8种施肥处理划分成两个主成分。植稻土壤,主成分1为NP、Nm、NPm和NPKm,主成分2为CK、N、m和NPK;植麦土壤,主成分1为m、Nm、NPm和NPKm,主成分2为CK、N、NP和NPK。主成分1的氨氧化细菌群落结构丰富度高于主成分2。水稻收获后土壤的氨氧化细菌群落结构丰富度高于小麦收获后土壤。【结论】施肥会改变石灰性紫色水稻土微生物的数量以及氨氧化细菌的种群结构,无机肥(N、NP、NPK)配施农家肥更有利于提高微生物的数量以及氨氧化细菌的种群结构进而维持土壤生物肥力状况。
