Objective To compare the efficacy and safety of excimer laser 308 nm phototherapy alone and the combination of excimer laser 308 nm and topical application of vitamine D3 alanogue tacalcitol in the treatment of vitiligo. Methods Seventy-eight patients with vitiligo were enrolled in the single-blind clinical trial, treated with excimer laser 308 nm. The lesions were devided into two groups: patients in the experimental group were instructed to use tacalcitol ointment and the control group were applied with placebo ointment. The lesions were evaluated once per month and photos taken for analyses of clinical effects. Results The results in different locations were compared, the effective rates of the experimental group in cephalofacial site, trunk and limbs were 93.51%, 84.16 % and 42.35 %, respectively. The effective rates of control group in opposite and adjacent sites were 90.9 %, 77.45 % and 34.15 %, respectively (P < 0.05). The comparison of results in different types of lesions indicated that the effective rate of the experimental group in vitiligo vulgaris and segmental vitiligo were 73.81% and 84.00 %, respectively. The effective rate of control group in vulgaris and segmental vitiligo were 86.8 %, 77.45 % and 34.15 %, respectively (P <0.05 ). The comparison of results in radiation times and doses of phototherapy showed that the radiation time and dose on the time of initial pigment regeneration were (16. 15 ± 3.22)times and (4.40 ± 5.03)J/cm2 in the experimental group, while ( 18.56 ± 3.50) times and ( 6.60 ± 1.01 ) J/cm2 ( P < 0.05 ) in the control group, the time and dose on the time of apparent effect were ( 20. 36 ± 1.50 ) times and ( 7.50 ± 3.54 ) J/cm2 in the experimental group, and (21.68 ± 2.40) times and( 8.80 ± 9.24)J/cm2 (P < 0.05 ) in the control group. Conclusion Application of tacalcitol ointment in combination with twice-weekly 308 nm excimer laser light phototherapy is an effective alternative treatment for patients with generalized vitiligo.

AIM: To observe effect of the iris location to femtosecond - combined wavefront guided LASIK for myopia and astigmatism.?METHODS:The patients with astigmatism >1. 0D during the same time and followed up for 1a were selected. A total of 129 eyes in 67 patients were treated under iris location with femtosecond-combined wavefront guided LASIK ( experimental group) and 161 eyes in 82 cases with femtosecond-combined wavefront guided LASIK ( control group) . Laser cutting went with the same laser machine. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) , and wavefront aberration between the two groups were compared at 1, 3, 6mo and 1a after surgery.?RESULTS:At 1 and 3mo after surgery, the number of patients with better postoperative UCVA than preoperative BCVA between the two group showed a statistically significant difference (χ2=6. 423, P=0. 011,χ2=14. 431, P=0. 01 ); at 1d and 1mo after surgery, the residual astigmatism showed a statistically significant difference between two groups (t=1. 98, P<0. 05; t=2. 23, P<0. 05). At 3, 6mo and 1a after surgery, the differences on the change of residual astigmatism between the two groups weren’t significant ( P > 0. 05 ). At 6mo and 1a after surgery, the differences on UCVA between the two groups weren’t significant ( P > 0. 05 ). Until 1a after surgery, the root mean square ( RMS ) of high order wavefront aberration of the two groups, spherical aberration and coma aberration ( COMA ) were all enhanced compared to before surgery(P<0. 05). At 1, 3mo after surgery, the RMS showed a statistically significant difference between two groups (P<0. 05). At 1, 3, 6mo, 1a after surgery, the increase of COMA in experimental group was significantly lower than that in control group (P<0. 05).? CONCLUSION: Iris location technology applied in femtosecond - combined wavefront guided LASIK for myopia and astigmatism, can make the vision recovery faster, the RMS of high order and COMA increase less, the residual astigmatism less, show better and more stable treatment effect.

AIM:To contrast analysis of postoperative variation of corneal posterior surface heights after Femtosecond LASlK ( FS - LASlK ) and small incision lenticule extraction ( SMlLE) for high myopia.
●METHODS: Sixty-seven cases of high myopic patients (132 eyes) operated with laser corneal refractive in our hospital from May to Dec. in 2015 (-6. 00D≤spherical equivalent degree≤-10. 00D) were selected and divided into FS-LASlK group and SMlLE group. The thickness of corneal flaps at FS-LASlK and the thickness of map at SMlLE were designed to be 110μm. Corneal posterior surface heights were examined by Pentacam at preoperation, postoperative 3 and 6mo after FS-LASlK and SMlLE operation. Surface height changes after preoperative, postoperative 3 and 6mo were compared by measuring Pentacam corneal analysis system.
●RESULTS: Six months after operation, the FS-LASlK posterior corneal surface height was 6. 47 ± 1. 65mm, significantly higher than 5. 20 ± 1. 32mm before operation. SMlLE posterior corneal surface height was 6. 40 ± 1. 33mm, significantly higher than 5. 18 ± 1. 25mm before operation, the differences were statistically significant( P<0. 05). Six month after surgery, two methods of corneal surface height variation obtained was 1. 29 ± 1. 28mm and 1. 22 ± 0. 89mm, there was no significant difference ( P>0. 05).
●CONCLUSION:After FS-LASlK and SMlLE, the corneal posterior surface is protrusive. FS - LASlK is slightly obvious than SMlLE in early period. The stability of the posterior surface is better after SMlLE.

Objective To evaluate the effect of early continuous renal replacement therapy(CRRT)on patients with acute kidney injury(AKI)induced by severe sepsis. Methods A prospective study was conducted. 160 patients with AKI induced by severe sepsis admitted to intensive care unit(ICU)of Qingyuan People's Hospital between October 2009 and June 2013 were enrolled. According to the starting time of CRRT,the patients were randomly divided into two groups:an earl y treatment group and a regular treatment group(each,80 cases). All patients were treated in accordance with the principle of the cluster of severe sepsis. In early treatment group,the patents began to receive CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment over 6 hours,but the curative effect was not ideal. In the regular treatment group,the patients began to apply CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment persistently over 24 hours or difficultly corrected acidosis or heart failure developed. The changes in urine output,creatinine,saturation of blood oxygen,and albumin,and 28-day survival rate,length of ICU stay,time of organ support were measured and compared between the two groups to evaluate the therapeutic significance of the early CRRT. Results The mean length of ICU stay(day:6.5±1.7 vs. 8.2±1.6),length of organ support(day:5.3±1.8 vs. 6.0±1.4),the recovery time of urine amount(day:3.4±0.9 vs. 4.8±0.5)in early treatment group were significantly shorter than those in regular treatment group(all P<0.01);recovery ratio of urine in 1 week in early treatment group was significantly higher than that in regular treatment group(46.2%vs. 28.8%,P<0.05). The creatinine recovery ratio in 1 week in early treatment group was lower than that in regular treatment group(55.0%vs 78.8%),but there was no statistically significant difference(P>0.05). Early treatment group and regular treatment groups of creatinine recovery time were similar(day:5.1±1.3 vs. 5.2±1.2). 28-day survival rate in early treatment group was higher than that in regular treatment group(41.2%vs. 35.0%),but there was no statistically significant difference(P>0.05). Conclusion It is found that there is no evidence to suggest that early CRRT may improve the prognosis of the patients with AKI induced by severe sepsis,but it may be in favor of shortening the time of urine recovery,length of stay in ICU,length of organ support and length of dialysis.
