■臭氧可以增强富血小板血浆(PRP)中某些生长因子(GFs)的表达,最近的研究表明,富氧PRP(臭氧化PRP)对骨关节疾病有较好的治疗效果。PRP注射液已广泛用于面部年轻化的治疗,但充足的富氧PRP在面部年轻化中的功效尚未研究。
■首先,我们研究了臭氧处理是否可以增加体外PRP的GFs浓度。然后采用多种主客观检测方法,通过6个月的随访,评价足量(10~12mL,每次注射面颈部)富氧(臭氧化PRP)PRP注射液在面部年轻化中的效果。最后,我们调查了满意度,通过问卷调查对治疗的副作用和疼痛评分进行分析。
■通过ELISA测量体外用不同剂量的臭氧处理的PRP中主要GFs的浓度。临床图片,反射共聚焦显微镜(RCM)观察真皮胶原厚度,皮肤状况(包括斑点,紫外线(UV)点,棕色斑点,红色区域,毛孔,皱纹,在治疗前收集VISIA的质地和卟啉),并在治疗后每月进行随访,直到完成6个月的随访期。患者满意度,在随访期结束时收集副作用和疼痛评分.
■经高剂量臭氧处理的PRP(57μg/mL,臭氧/PRP体积比:1/1)在体外显示内皮生长因子(EGF)和转化生长因子-β(TGF-β)与基线相比显着增加(P<0.05)。额头的胶原蛋白厚度,直到治疗后6个月,脸颊和颈部与基线相比显着改善。斑点,UV斑点,棕色斑点,与基线相比,红色面积和质地显着改善(P<0.05)。所有参与者均报告改善,中位疼痛评分为4.19。未观察到严重不良事件。
■臭氧处理可以在体外增加PRP中EGF和TGF-β等GF的浓度。充足的富氧PRP注射可能是治疗面部年轻化的有效且有前途的方法。
UNASSIGNED: Ozone can enhance the expression of some growth factors (GFs) in platelet rich plasma (PRP), recent study showed oxygen-rich PRP (ozonized PRP) have better therapeutic effects on bone and joint diseases. PRP injection has been widely used in the treatment of facial rejuvenation, but the efficacy of sufficient oxygen-rich PRP in facial rejuvenation has not been studied.
UNASSIGNED: Firstly, we examined whether
ozone treatment can increase the concentration of GFs of PRP in vitro. And then a variety of subjective and objective detection methods were used to evaluate the effect of sufficient(10-12 mL each time for the injection of face and neck) oxygen-rich (ozonized PRP) PRP injection in facial rejuvenation by follow-up for 6 months. At last, we investigated the satisfaction, side effects and pain score of the treatment through a questionnaire survey.
UNASSIGNED: The concentration of main GFs in PRP treated with different dose of
ozone in vitro was measured by ELISA. Clinical picture, the collagen thickness of dermis by reflectance confocal microscope(RCM), skin conditions (including spots, ultraviolet (UV) spots, brown spots, red area, pores, wrinkles, texture and porphyrin) by VISIA were collected before treatment and each month follow-up visit after treatment until 6-month follow-up period was finished. Patients\' satisfaction, side effects and pain score were collected at the end of follow-up period.
UNASSIGNED: PRP treated by high-dose
ozone (57 μg/mL,
ozone/PRP volume ratio:1/1) in vitro showed a significant increase in endothelial growth factor (EGF) and transforming growth factor-β (TGF-β) compared to baseline(P < 0.05). Collagen thickness of forehead, cheek and neck improved significantly compare to the baseline until to the 6 months after treatment. Spots, UV spots, brown spots, red area and texture improved significantly compare to the baseline(P < 0.05). All of participants reported improvement and have a median pain score of 4.19. No serious adverse events were observed.
UNASSIGNED: Ozone treatment can increase the concentration of GFs such as EGF and TGF-β in PRP in vitro. Sufficient oxygen-rich PRP injection may be an effective and promising method to treat facial rejuvenation.
