简介:目的:观察加味桃红四物汤联合优化强脉冲光(OPT)治疗黄褐斑的临床疗效。方法:将240例患者随机分为单纯OPT组(A组)80例、加味桃红四物汤联合OPT(B组)80例及单纯加味桃红四物汤组(c组)80例,分别接受相应治疗,12周后用VISIA皮肤测试仪对患者色素斑进行定量分析和评价,并进行疗效评定。结果:研究共脱漏对象5例。三组有效率分别为68.80%、84.60%、55.80%,联合治疗组与其他两组比较差异均有统计学意义(X2值分别为10.35、18.38,P值均〈0.05);VISIA皮肤测试显示3组治疗后色素斑相对于治疗前绝对数值均有明显下降,差异有统计学意义(P值均〈0.05)。其中联合治疗组数值下降最明显,变化比率最高。治疗后,联合治疗组与OPT治疗组、中药治疗组VISIA评分比较差异均有统计学意义(t值分别为-2.98、-4.99,P值均〈0.05),而OPT治疗组与中药治疗组无统计学差异。患者耐受性好,无明显副作用。结论:三种疗法治疗黄褐斑均有效,其中应用桃红四物汤联合强脉冲光治疗黄褐斑疗效较好。
简介:利用改进的Riccati方程映射法和变量分离法,得到了联立薛定谔方程的新精确解。根据所得到的解模拟出了时间光孤子、光孤子脉冲,研究了光孤子间的弹性相互作用。

简介:摘要目的探析强脉冲光和调Q激光用于面部雀斑的治疗效果。方法选取2015年1月~2015年12月接诊的90例面部雀斑患者作为研究对象,并随机分为观察组和对照组各45例,分别给予两组患者采用强脉冲光和调Q激光进行治疗,观察比较两组患者的治疗时间、灼热感消退用时、色素消退用时。结果采用强脉冲光进行治疗的观察组治疗总有效率明显比采用调Q激光进行治疗的对照组高,两组比较差异具有统计学意义(P<0.05)。结论采用强脉冲光治疗面部雀斑的临床效果优于采用调Q激光进行治疗,其优势特点主要体现在能够有效缩短治疗时间,且安全可靠,不良反应较少,治疗效果显著,值得推广应用。
