目的 分析高压氧治疗对面部填充术后血管并发症的疗效。方法 将62例面部填充剂注射后并发症患者根据高压氧介入时机分为A组和B组,A组在在常规治疗的基础上,48小时内进行高压氧治疗,B组在在常规治疗的基础上,48小时后进行高压氧治疗,在治疗结束后对两组患者进行疗效分析。结果 A组患者的治疗疗效较B组患者治疗疗效好,差异有统计学意义(P<0.05)。结论 高压氧治疗对面部填充剂注射后并发症疗效是肯定的,且高压氧介入时间越早效果越好。

Objective To analysie effect of hyperbaric oxygen therapy on vascular complications after facial filling. Methods 62 patients with complications after injection of facial filler according to the timing of hyperbaric oxygen intervention were divided into group A and group B.Group A was treated with hyperbaric oxygen within 48 hours on the basis of conventional treatment.Group B was treated with hyperbaric oxygen 48 hours later on the basis of conventional treatment to analysie the efficacy of the two groups of patients after the end of treatment. Results The efficacy of group A patients was better than that of group B, the difference was statistically significant P<0.05. Conclusion Hyperbaric oxygen therapy is effective in the treatment of complications after facial filler injection, and the earlier the hyperbaric oxygen intervention time is taken, the better the effect is.

目的 探讨高压氧对FVB小鼠旷场行为的影响。方法 对9只4周龄高压氧组FVB小鼠进行2个疗程共21天高压氧干预;对13只4周龄对照组FVB小鼠不做任何处理,正常饲养。21天后对2组小鼠进行旷场实验,观察高压氧对FVB小鼠旷场行为的影响。结果 高压氧组小鼠在中央区停留时间(3.73±3.69,17.97±6.82,t=-5.564,P=0.000)和运动路程较对照组小鼠减少(189.65±199.32,525.67±244.22,t=-3.298,P=0.040),在外周区停留时间增加(296.07±3.69,281.79±6.79,t=5.597,P=0.000);进入中央区、外周区次数及穿越各区总次数都减少(3.11±3.10,8.20±4.80, t=-2.770,P=0.014;3.11±3.10,9.10±4.79,t=-3.264,P=0.005;6.22±6.20,17.30±9.59,t=-3.018,P=0.008);2组小鼠总路程和平均速度无差异(8766.57±3362.90,8320.47±1692.47, t=0.359,P=0.726;73.05±28.02,69.34±14.10,t=0.359,P=0.726)。结论 高压氧改变FVB小鼠的旷场行为的表型,使小鼠趋避性增加,对环境的认知能力及焦虑程度增强,探索性下降。

Objective To explore the effect of hyperbaric oxygenation(HBO)on behaviors of FVB mice in the open field test. Methods 9 mice of four-week-old in the HBO group were treated with hyperbaric oxygenation for a total of 21 days during two courses while 13 control mice of four-week-old did not do any treatment. After 21-day normal breeding, the mice of two groups were tested with open field test. Then, researchers observed the effect of hyperbaric oxygenation on mice behaviors after open field test. Results Compared to 13 control mice, residence time (3.73±3.69,17.97±6.82,t=-5.564,P=0.000) and the range of movement (189.65±199.32,525.67±244.22,t=-3.298,P=0.040)in central region decreased while the residence time in external region increased (296.07±3.69,281.79±6.79,t=5.597,P=0.000). The times of entering the central region and external region and crossing both of the regions decreased (3.11±3.10,8.20±4.80, t=-2.770,P=0.014;3.11±3.10,9.10±4.79,t=-3.264,P=0.005;6.22±6.20,17.30±9.59,t=-3.018,P=0.008). There was no difference in the total range of movement and the average velocity (8766.57±3362.90,8320.47±1692.47, t=0.359,P=0.726;73.05±28.02,69.34±14.10,t=0.359,P=0.726). Conclusion Hyperbaric oxygenation may change the behaviors of FVB mice in open field test to enhance its phobotaxis, anxiety degree and the cognitive ability in environment and inhibiting its exploration ability.
