简介：目的：探讨卡泊三醇治疗前后银屑病皮损中Caspase-3和bcl-2中的表达及意义。方法采用免疫组化技术对12例银屑病患者经卡泊三醇治疗前后皮损及非皮损区皮肤中Caspase-3和bcl-2表达进行检测。结果经卡泊三醇治疗后银屑病患者皮损角质形成细胞中bcl-2的表达明显增加（P＜0.05），Caspase-3的表达无明显差异（P＞0.05）。结论卡泊三醇治疗银屑病的可能作用机制之一是促进bcl-2诱导角质形成细胞的凋亡。

简介：目的探讨复方红花酊对TNF-α和IL-10的影响及促进黑色素形成作用。方法实验动物随机分为正常对照组、模型组、阳性对照组（复方卡力孜然酊）、复方红花酊高剂量组、中剂量组、低剂量组。建立白癜风皮损模型，并应用相对应药物涂擦治疗，测量其TNF-α和IL．10平均光密度及黑色素颗粒细胞数目，比较其作用。结果复方红花酊高、中剂量组及阳性对照组对皮损有复色作用；与正常对照组比较，模型组TNF-α的表达显著增高，IL-10的表达明显减少，黑色素含量明显降低，差异有统计学意义（P〈0．05）；与模型组比较，复方红花酊高、中剂量组及阳性对照组中TNF-α的表达明显降低，IL-10的表达明显增高，各组黑色素含量均明显增加，差异有统计学意义（P〈0．05）；复方红花酊高、中剂量组及阳性对照组中的TNF-α表达水平与黑色素含量呈显著负相关（P〈0．05），IL-10表达水平与黑色素含量呈显著正相关（P〈0．05）。结论复方红花酊通过调节TN-α和IL-10的表达水平可影响黑色素的生成，进而对白癜风产生一定的治疗作用。

简介：目的首次报道3例大观霉素治疗淋病失败病例，对其原因进行了研究分析。方法以氧化酶试验和糖发酵试验鉴定3株淋球菌，用琼脂稀释法进行体外药物敏感性试验。结果3株菌均氧化酶阳性，糖发酵试验仅分解葡萄糖，鉴定为淋球菌。药物敏感性试验3株淋球菌均对头孢曲松敏感，对环内沙星耐药；2株淋球菌为耐大观霉素淋球菌，其中1株亦为产青霉素酶淋球菌(PPNG)；第3株淋球菌为大观霉素敏感菌株，但为PPNG及耐四环素淋球菌(TRNG)。病史提示第3例患者是因为药物注射不当或吸收剂量不足而至治疗失败。结论大观霉素治疗淋病失败的原因有耐药问题，还有注射不当。
