AlM:To observe clinical effects between the laser in situ keratomileusis ( LASlK ) surgery and the laser subepithelial keratomileusis ( LASEK ) surgery as the second operation after an unsuccessful LASlK surgery.METHODS:Forty-nine patients (98 eyes) with refractive regression after LASlK operation received the second surgery. All patients were divided into two groups:group A and B. Group A (48 eyes of 24 patients) received LASlK surgery and group B ( 50 eyes of 25 patients ) received LASEK surgery. lnspect the main parameters included visual acuity, refraction, corneal curvature, and the total value of high-aberration after 1wk, 1mo and 1a, t-test of groups was used as statistical analysis method.RESULTS: There was statistically significant (P<0. 05) between the two groups in visual acuity after 1wk. There was no statistically significant between the two groups in visual acuity after 1mo, and there was also no statistically significant between the two groups in visual acuity, average spherical equivalent refractive degree, average corneal curvature, and the total value of high-aberration after one year (P>0. 05). There developed one case of epithelium in growth after LASlK surgery, and one case of haze Ⅱ after LASEK surgery.CONCLUSlON: Both LASlK and LASEK surgery can obtain satisfactory therapeutic results after an unsuccessful LASlK surgery.

Objective To systematically review the correlation between polymorphisms of CYP2D6 genotypes and concentrations of tamoxifen and its activity in Chinese breast cancer patients.Methods Such databases as Cochrane Library, PubMed, EMBase, CNKI, CBM, WeipuData and WanfangDate,from January 1995 to October 2014 were searched on line for the studies about the correlation between polymorphisms of CYP2D6 genotypes concentrations of tamoxifen and its activity in Chinese breast cancer patients.And references about it were checked.The meta-analysis was performed with RevMan 5.3 software.Results A total of 4 articles involving 438 patients were included.The results of meta-analysis showed that,the concentrations of HTAM and endoxifen in patients who had CYP2D6*10/*10 genotypes were lower than the other genotypes ( P<0.0001 ) .The concentration of tamoxifen in patients who had CYP2D6*10/*10 genotypes was lower than CYP2D6Wt/Wt ( P<0.05 ) .There was no significant difference between CYP2D6Wt/Wt and CYP2D6Wt/*10.Conclusion We concluded that CYP2D6 polymorphisms may influence concentrations of tamoxifen and its activity in Chinese breast cancer patients.

Objective To explore the role of oxygen free radicals in the proliferation of ECV304 induced by AngⅡ.Methods The lines of human umbilical vein endothelial cell(ECV304)cultured in vivo were divided into three groups which were treated by AngⅡ,AngⅡ+N-acetyl-L-cysteine(NAC),and normal culture medium.First we observed the proliferous effect of ECV304 induced by AngⅡat different concentration with improved MTT and microscope.Then the contents of oxygen free radicals(?OH)in three groups were detected by spectrophotometer.Results ECV304 incubated with AngⅡ(0.03125～1?mol/L)for 12 hours increased the proliferation rate(P 0.05 vs.control group).Conclusions ECV304 induced by AngⅡcan produce oxygen free radicals(?OH),and the contents of oxygen free radicals(?OH) increase with the prolongation of time and the enlargement of dose;Antioxidant NAC can inhibit the proliferation of ECV304 induced by AngⅡ,this effect may be related with reducing the content of oxygen free radicals(?OH);oxygen free radicals(?OH)may be one of the major mocleculars which play an important role in the signal transduction of ECV304 proliferation.

? AlM: To analyze the reason of corneal epithelial implantation and ingrowth after laser in situ keratomileusis ( LASlK ) , and summarize the treatment experiences.
?METHODS: The clinical data of postoperative corneal epithelial ingrowth on 18 cases (30 eyes) from 1 256 cases (2 256 eyes) after LASlK were retrospectively analyzed in our hospital from January 2008 to December 2012. After the treatment of all eyes, patients’ general visual quality scores before and after treatment were analyzed.
?RESULTS:There were 18 cases ( 30 eyes ) with corneal epithelial implantation and ingrowth after LASlK, and the incidence rate was 1. 3%. ln the 18 cases (30 eyes), there were 12 eyes corneal flap epithelial ingrowth caused by postoperative trauma, 12 eyes caused by multiple corneal flap flush, 2 eyes caused by intraoperative irregular corneal flap, and nothing special for 4 eyes. The classification of corneal epithelial ingrowth of 30 eyes:grade I, 11 cases (18 eyes);gradeII, 4 cases (8 eyes);grade Ⅲ, 3 cases ( 4 eyes ) . Grade I-II were treated with TobraDex eye drops and intraocular pressure lowering drug. Grade Ⅲ firstly were treated by drugs, otherwise by surgery if it didn’t improve. After treatment, 8 cases (13 eyes) epithelial ingrowth disappeared from 11 cases ( 18 eyes ) , 3 cases ( 5 eyes ) implanted epithelial tumor shrank in grade l;epithelial implantation of 2 cases (4 eyes) in grade II disappeared, implantation degree of 2 cases (4 eyes) reduced to grade I;2 cases (2 eyes) in grade Ⅲ had 0. 5 ~ 1mm wide flap edge shallow gray ribbon 1 mm inside the limbus, visual acuity was 0. 8 ~1. 2, 1 case ( 2 eyes ) treated with curettage corneal epithelial implantation and endophytic epithelium hadn’t relapsed in the follow-up. After the treatment, 18 cases of corneal epithelial ingrowth got lower visual quality scores than those before therapy (Hc=10. 511, P<0. 01).
?CONCLUSlON: Operation standardized, postoperative early detection and aggressive treatment are important for prevention and treatment of complications after LASlK.

OBJECTIVE:To explore the method and efficacy of occlusion with medicinal albumin gel for esophageal fistula. METHODS:Over the recent 5 years,a total of 11 patients with esophagus -respiratory fistula or esophagus-neck fistula confirmed by iodine imaging and / or gastroscopy were occluded with medicinal albumin gel under endoscope. RESULTS:The occlusion with medicinal albumin gel for esophageal fistula was successful in all the 11 cases,and 9 out of 11 were completely healed after one time occlusion treatment and the other 2 cases were completely healed after the second occlusion treatment. The average hospital stay was 27 days and the average cost was 24,500 yuan. There was no recurrence after follow-up of 3 to 6 months,nor was there any adverse complication. CONCLUSION:Compared to the conventional conservative treatment,occlusion with medicinal albumin gel for esophageal fistula under endoscope can reduce the length of hospital stay and the cost of hospitalization.
