Background:Hair loss from cytotoxic drugs is classically ascribed to the loss of fractured hairs (anagen effluvium). Telogen hair loss has also been described but some authors have denied any effect on the hair cycle. There are conflicting reports on a protective effect of pretreatment with a vitamin D analogue on cytotoxic drug-induced hair loss in rodents. Objectives:To investigate the process of cytotoxic hair loss and any protective effect on the hair of pretreatment with topical calcipotriol. Methods Breast cancer patients who were about to receive cycles of chemotherapy with cyclophosphamide 600 mg m-2, methotrexate 40 mg m-2 and 5-fluorouracil 600 mg m-2 were recruited and randomized to receive calcipotriol scalp solution 50 μg mL-1 or vehicle. The solution was applied twice daily from 4 days prior to chemotherapy and continued for 14 days in each treatment cycle. Shed, plucked and cut hairs were sampled. Absolute shed rates, the proportion of major hair types, the presence of proximal hair shaft changes, regrowth (using the new anagen hair count) and hair density were assessed. results:Ten patients receiving calcipotriol and 14 receiving vehicle completed three treatment cycles and nine from both groups completed six cycles. There was no detectable effect of calcipotriol on the proportion of patients experiencing minimal hair loss from chemotherapy, shed rates, plucked telogen and fractured hair counts, the morphology of shed and plucked hair, hair regrowth or hair density. Combining results of the treatment groups, there was a large variation in the impact of chemotherapy on hair loss, from total loss in five patients to no obvious loss in five. Excluding the latter, during chemotherapy shed telogen hairs (mean 81%of shed hairs) predominated over fractured (12%) and anagen hairs (6%) (P=0.0002). The major pathological change was proximal hair shaft tapering, baseline mean 3%of shed hairs rising to 48%(P=0.0005) during treatment, and there was a consequent d

研究了结构钢单道次焊接接头,尤其是靠近融合线位置的粗晶热影响区(CGHAZ)的组织和力学性能。通常,这个区域的韧性比母材和焊缝金属的韧性要低很多,所以CGHAZ是最容易发生断裂的薄弱位置。重点关注钒微合金化钢板,并且与相同强度级别的铌微合金化钢板进行对比。为了充分利用钒的强化效果,有必要将氮含量提高至0.01%;为优化钢的性能,必须考虑钒与氮的配合。
