ABSTRACT
Objective:To explore the application of Lux? 1540 nm non-ablative fractional laser in the coarse pores.Methods:A total of 100 patients were treated with Lux? 1540 nm non-ablative fractional laser once a month for rough facial skin and thick pores, with a total of 4 times of treatment. Subjective evaluation and photo evaluation were used to evaluate the therapeutic effect one month after treatment.Results:The facial skin roughness and pore roughness improved after treatment, and the differences were statistically significant ( t=21.345, P<0.05). After treatment, 80 patients were much satisfied, 17 were satisfied, and 3 were dissatisfied, with a satisfactory rate of 97%. Conclusions:Lux? 1 540 nm non-ablative fractional laser has a positive therapeutic effect on rough skin and thick pores, with high safety and few side effects.
ABSTRACT
Objective To explore the application of Lux1540 nm non-stripping array laser in fa-cial rejuvenation .Methods A total of 100 patients were collected for Lux1540 nm non stripped lattice laser treatment in patients with facial skin aging ,once a month ,totally four times treatment ;1 month after the treatment ,the skin of patients was analyzed by skin image analyzer VISIA for quantitative e-valuation .Results After 4 treatments ,the skin wrinkles ,texture ,pores ,skin roughness ,brown spots ,erythrocyte and purple spots were all improved ,with statistically significant differences (P <0 .05) ,while the changes of ultraviolet spots were not obvious ,and the differences were not statistical-ly significant (P > 0 .05) .After treatment ,80 patients were satisfied ,17 were comparatively satisfied , and 3 were dissatisfied ,with a satisfactory rate of 97％ .All patients had needle-like pain during the treatment ,which could be tolerated without local anesthesia ointment .Ice compress was given after treatment ,which significantly alleviated the discomfort after treatment .Only 3 cases had mild pig-mentation .During the treatment and follow-up ,no adverse events such as skin redness and swelling , pigmentation and pruritus were found .Conclusions Lux1540 nm non-ablative dot array laser has posi-tive efficacy ,high safety and few side effects in facial rejuvenation ,and it is an effective method to treat facial skin aging .
ABSTRACT
Objective To investigate serum total IgE levels of healthy population in two hospitals in Yantai and Weihai areas,to investigate the influencing factors of the levels of serum total IgE,which can provide information for the clinical diagnosis of allergic diseases.Methods The total serum IgE level was measured with chemiluminescence method in 1 200 cases of healthy people and 600 cases of smoking group in different age groups.Results The total IgE level of ≤6 years was (28.53±20.71)IU/mL,7-12 years was (29.74±25.94)IU/mL,13-18 years was (32±22.32)IU/mL,19-44 years was (45.2±36.27)IU/mL,45-60 years was (35.47±27.23)IU/mL,>60 years was (31.2±25.03)IU/mL.There was no effect of serum total IgE in different age groups:≤6 years,7-12 years,13-18 years,45-60 years,>60 years(t=0.610,1.508,0.777,0.160,1.518,all P>0.05),19-44 years was significantly different from other age groups(t=0.075,P0.05).The total IgE level of the smoking group:19-44 years was (55.22±39.16)IU/mL,45-60 years was (42.63±28.46)IU/mL,>60 years was (39.32±26.73)IU/mL.The level of serum IgE in the smoking group was significantly higher than that in the same age group (t=0.142,0.174,0.235,all P<0.05).Conclusion No significant difference existed in healthy people of serum total IgE levels from birth to adulthood.However,the total IgE level rose when reached to 19-44 years,which then slightly declined as the growth of the age.There was no significant difference between male and female of the IgE levels in different age groups.But after the age of 19,smoking can lead to the increase of the total IgE level.
ABSTRACT
Objective To investigate the feasibility, rationality and efficacy of the autologous dermal-fat composite tissue used as filling materials in the repair of nasal dorsum collapse.Methods The dermal fat composite tissue block (7.0 cm× 1.0 cm × 1.0 cm) was removed from the buttocks or abdoman as filling materials. 13 cases of nasal dorsum and nasal-shaped misfits were treated by using an umbrella graft of the auricular cartilage plus dermal-fat composite tissue graft to reconstruct natual shape of nasal dorsum and tip. Results The nasal dorsum and tip were repaired in 13 patients with collapsed nasal dorsum. The dermal-fat composite tissue survived well, and the incisions were healed in stage Ⅰ and the incision trace was not obvious. After follow-up for one year, the shape of nose was much satisfactory. Conclusion It is a well-accepted and easy-going procedure to repair collapsed nasal dorsum with autologous dermal-fat or a combination of composite ear cartilage tissue graft, with satisfactory effect and no rejection reactions.
