? 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.

To survey the serum uric acid (SUA) levels and associated risk factors of hyperuricemia among youth and middle-aged residents in Guangzhou.A total of 1420 subjects,aged from 20 to 60 years,receiving health check-up at our hospital in 2010 were enrolled.The total prevalence of hyperuricemia was 22.04％,32.01％ in males and 14.07％ in females.The average SUA was (388 ±78) μmol/L in males and (288 ± 63) μ mol/L in females.The prevalence of hyperuricemia in males was 30.11％ before 40 years of age and 33.81％ between 40 and 60 years of age.The average level of SUA in males was significantly higher than that of females.logistic regression analysis showed that BUN,body mass index (BMI) and hypertriglyceridemia were the independent risk factors of disease while HDL-C and gender (females) the protective factors.

Objective To retrospectively analyze the influence factors during autologous peripheral blood stem cell (PBSC) mobilization and collection process in the patients with non-Hodgkin′s lymphoma (NHL).Methods Forty-eight patients with NHL in our hospital from January 2014 to August 2016 underwent PBPC mobilization and collection.The factors of age,sex,disease stage,bone marrow involvement at diagnosis,chemotherapy frequency,relapse and so on were analyzed retrospectively.Results PBSC mobilization and collection was successful in 37 cases (77.10%).The success rate was affected by the time from diagnosis to mobilization (P=0.038),chemotherapy courses (P=0.016),prior chemotherapy including fludarabine (P=0.049),relapse(P=0.033),and the levels of white blood cell (P=0.014) and platelet (P<0.01) before stem cells collection.Conclusion For the patients planning to receive autologous peripheral blood stem cell transplantation,many times of prior chemotherapy are unfavorable,mobilization and collection should be taken as early as possible,chemotherapeutic agents which possibly injure stem cells should be avoided,it is needed to simultaneously pay attention to peripheral blood WBC and platelet level for determining the collection timing.

Objective To evaluate whether estradiol can inhibit and cure the inflammation of experimental preeclampsia in rats. Methods Experimental preeclampsia was induced in 14-day-pregnant rats by infusion of endotoxin (1.0 ?g/kg). Rats with normal pregnancy were infused with sodium chloride solution.A group of preeclampsia rats was injected with 17?-estradiol (17?-E_2, 1 mg?kg -1 ?d -1 ). Blood pressure, albuminuria,inflammation associated adhesion molecule CD_ 49d and tumor necrosis factor-?(TNF-?) were assessed. Results On pregnant day 19, for normal pregnancy group(group C) the blood pressure was (120.4?2.0)mm Hg (1 mm Hg=0.133 kPa),urinary protein (0.47?0.06)mg/24 hours;for experimental preeclampsia group(group A) blood pressure was (134.2?2.4) mm Hg,urinary protein(0.79?0.10)mg/24 hours; for experimental preeclampsia with 17?-E_2 treatment group (group B) blood pressure was(123.3?1.7)mm Hg,urinary protein (0.51?0.08)mg/24 hours. A significant increase of blood pressure and urinary albumin was observed in group A. CD_ 49d expression and TNF-? concentration were also increased. 17?-E_2 reduced the expression of CD_ 49d , concentration of TNF-?,blood pressure and albuminuria of experimental preeclampsia. However, the weight of fetuses in 17?-E_2 treatment group were less than that in other groups. Conclusion 17?-E_2 can improve the symptoms of experimental preeclampsia,but its effects on fetus need to be further studied.

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

OBJECTIVETo investigate the protective effects of daidzein (DD) on ventricular remodeling in rats with myocardial hypertrophy induced by pressure overload and its mechanism.

METHODMyocardial hypertrophy model of rats induced by pressure overload was prepared by constricting abdominal aorta. The operated rats were randomly divided into sham operated control group, aorta-constricted model group and three DD groups (30, 60, 120 mg kg(-1)). Four weeks later, the heart-weight (HW), left ventricular weight (LVW), the ratio of HW/BW and LVW/BW (LVI) and the cardio-myocyte diameters (MD) after dyeing by HE colar were measured. The hydroxyroline, nitric oxide (NO) and the activity of nitric oxide synthetase (NOS) and Na+ -K+ -ATPase, Ca2+ -ATPase in left ventricle were quantified with spectrophotometry and the angiotension II (Ang II) in left ventricle and serum was messured with radioimmunoassay.

RESULTAfter treatment of the left ventricular with DD, vs aorta-contricted model group, NO content, cNOS and Na+ -K+ -ATPase, Ca2+ -ATPase activity were significantly increased, the content of AngII in left ventricle and serum and iNOS activity and the ratio of HW/BW, LVI, MD were significantly reduced.

CONCLUSIONDD has protective effects on ventricular remodeling in rats with myocardial hypertrophy induced by pressure overload and its mechanism may be related to raising NO content and reducing the level of Ang II.
