Although the variability in compliancewith posttreatment tretinoin and sunscreen use is another limitationof the study, the researchers report,"We do not believe that any significant differencein posttreatment regimen adherence existed among the 3 studyarms or biased our results for actinic keratoses reduction or nonmelanoma skin cancer development."

虽然治疗后使用Tretinoin和防晒霜的变数是本研究的另一个限制，作者报告指出，我们不认为在三个研究组的治疗后处方中有任何显著差异，也不认为对我们的减少光化性角化病和预防非黑色素皮肤癌结果有任何偏见。

The Food and Drug Administration of USA hasapproved the use of this topical medicine for treatment of different malignant andpremalignant tumors such as actinic keratoses and basal cell carcinoma. Althoughimiquimods exact mechanisms of action in neoplastic diseases has not yet been fullyelucidated, animal and human studies have shown its ability to enhance the productionof cytokines such as interferon-, interleukin-12, and tumor necrosis factor- though conjugations with Toll like receptors on the surface of dendriticcells of the monocyte-macrophage lineage.

有关咪喹莫特抗癌作用的具体机制仍不十分明了，一般认为，咪喹莫特主要是通过与免疫相关细胞表面的Toll样受体结合、促进IFN-α、TNF-α、IL-12等多种前炎症细胞因子的分泌，进而激活天然与获得性免疫反应的方式发挥抗癌作用；进一步的研究发现，咪喹莫特尚能选择性的抑制某些皮肤肿瘤细胞的增殖并诱导其凋亡，提示增殖抑制和诱导凋亡可能是评价咪喹莫特抗肿瘤作用的重要指标和机制。

Reporting in the August issue of the Archives of Dermatology , Dr. Swetter and her team present the findings of their randomized prospective 5-year trial. Looking at patients with previous nonmelanoma skin cancer and severe sun damage, the group studied the effect of facial resurfacing for the treatment of actinic keratoses and prophylaxis againstnew primary basal- and squamous-cell carcinomas.

该报告登载於八月版的皮肤医学档案期刊，Swetter医师和她的团队报告此一随机前溯的五年试验研究发现，著眼於非黑色素皮肤癌和严重晒伤病患，研究脸部皮肤重建整形治疗光化性角化病，和预防初发基础细胞癌以及鳞状细胞癌的效果。

Multiple CSCCs carry a high risk of subsequent primary skin cancer. CSCCs arising in a scar have higher rate of recurrence or metastasis than those occurring in actinic keratoses. A patient presented with primary CSCCs on the ankle and wrist.

多处原发性皮肤癌病患比起一般皮肤癌患者，有更高的机会发生次发性皮肤癌，且源於疤痕或慢性砷中毒的扁平上皮细胞癌，其侵袭性、复发率、转移可能性，及并发其他疾病的可能性也比源於紫外线暴露者为高。

Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles that disappear when stretched, loose skin, a blotchy complexion, actinic keratoses (thick wart-like, rough, reddish patches of skin), and skin cancer can all be traced to sun exposure.

雀斑、色斑、脸上的红血丝、粗糙皮革化的皮肤、小细纹、皮肤松弛、肤色不匀、日光性角化病(一种厚伽，粗糙，鳞片状的皮肤病)，以及皮肤癌都能在阳光照射上找到原因。

Porphyrins and metalloporphyrins have good optical and thermal stability, their absorption spectra lie in visible area. And they have many physical and chemical characters, so they are widely used in biochemistry, medical chemistry, analytical chemistry, actinic catalysing and meterial chemistry.

卟啉及金属卟啉具有良好的光和热稳定性，其吸收光谱在可见光范围内，具有许多独特的物理、化学性质及其它功能性质，因而在生物化学、药物化学、分析化学、光化催化和材料科学等领域都得到广泛的关注和应用。

With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.

为探究NaHSO〓促进高等植物光合作用的机理，我们研究了NaHSO〓对小麦（京411）和水稻（汕优63）围绕PSI的循环电子传递影响，实验发现低浓度NaHSO〓可促进小麦和水稻叶片的叶绿素荧光在作用光关闭后的短时上升以及缩短叶片在远红光后P700〓再还原的半时间，表明NaHSO〓可以促进小麦和水稻的围绕PSI的循环电子传递。
