AIM:To investigate the effect of the size of cataract surgical incision on original astigmatism and tear film stability of corrected cornea.METHODS: Totally 92 cataract patients (92 eyes) who were admitted to our hospital from July 2014 to July 2016 were randomly divided into the control group and the observation group,46 cases (46 eyes) in each group.Both groups were treated by clear corneal tunnel incision phacoemulsification combined with intraocular lens implantation.The incision of the control group was 3.0mm while of the observation group was 1.8mm.The uncorrected visual acuity,corneal astigmatism,Schirmer I test (SⅠt) and break-up time (BUT) were detected before surgery and at 1d,1wk,1mo and 3mo after surgery.The surgery induced astigmatism (SIA) was recorded at 1d,1wk,1 and 3mo after surgery.RESULTS: There were significant differences in the uncorrected visual acuity between the two groups at 1 and 3mo before surgery (P<0.05),but there were no significant differences at different time points before and after surgery (P>0.05).At 1wk,1 and 3mo after surgery,SIA of two groups decreased continuously,and the SIA of the observation group was significantly lower than that of the control group at 1d,1wk and 1mo after surgery (P<0.05).At 1wk after surgery,SⅠt and BUT in the two groups were less or shorter than those before surgery (P<0.05),but there were no significant differences at 1mo,3mo after surgery,compared with those before surgery (P>0.05).SⅠt and BUT in the observation group were less or shorter than those in the control group at 1wk after surgery (P<0.05) but there were no significant differences at 1 and 3mo after surgery (P>0.05).CONCLUSION: Compared with 3.0mm standard incision,1.8mm clear corneal incision can reduce SIA and shorten the time for corneal stability recovery.

Objective:To investigate the effect of genistein,a soybean-derived isoflavone,on thestimulating effect on bone resorption of IL-1?.Methods:The osteoclasts(OCs)were isolated with themethods of Yu Shifeng.The rat calvaria were cultured as an organ.The cells in the experiment weregrown in four respectively:Control(without genistein or IL-1?),10~(-6) mol/L genistein,10 ?g/L IL-1?and 10~(-6) mol/L genistein+10 ?g/L IL-1?.The area of bone resorption,the concentration of Ca~(2+) in thesupernatant liquid of OCs cultures and mice calvaria were tested.The contents of acid phosphatase(ACP)were also examined by biochemistry method.The index of bone resorption was counted as the ra-tio of the experiment average and control ones,which indicated the increase in bone resorption when itwas above 1.0.Results:The area of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? increasedcompared with that of 10~(-6) mol/L genistein,while the concentration of Ca~(2+) in the supernatant liquid ofOCs cultures decreased significantly.The index of bone resorption of 10~(-6) mol/L genistein+10 ?g/L IL-1? lied between 10~(-6) mol/L genistein and 10 ?g/L IL-1?.In the organ culture,there was no differencein the content of ACP among all the groups,The index of bone resorption of 10~(-6) mol/L genistein+10?g/L IL-1? was below that of 10?g/L IL-1?,but both were above 1.0.The index of bone resorptionwas below 1.0 in the group of 10~(-6) mol/L genistein.Conclusion:Genistein can suppress obviously thebone resorption simulated by single IL-1?.

Objective To analyze lesional and clinical characteristics of Langerhans cell histiocytosis in children.Methods A clinical retrospective study was performed on 126 patients with Langerhans cell histiocytosis collected from 2006 to 2011 at the Hunan Children's Hospital.Results Of the 126 patients,the youngest was 2months old,and the oldest was 9 years old.The ratio of male to female was 2.5 ∶ 1.Clinical manifestations included eczematid,seborrheic lesions,hemorrhagic maculopapules,yellow nodules and white macules.Of the three clinical phenotypes of Langerhans cell histiocytosis,Letter-Siwe disease was the most prevalent,and most cases of LetterSiwe disease were associated with hepatosplenomegaly,abnormal chest X-ray,impaired hematopoietic function and multifocal bone injuries.The clinical grade was mainly Ⅲ and Ⅳ in patients with Letter-Siwe disease,Ⅰ in patients with eosinophilic granuloma,and varied from Ⅰ to Ⅳ in patients with Hand-Schuller-Christian disease with Ⅱ as the most common.Of these patients,those with eosinophilic granuloma had the oldest average age with bone as the only affected organ,while those with Letter-Siwe disease had the youngest average age with the greatest number of affected organs.The treatment of Langerhans cell histiocytosis included surgical operation and combined chemotherapy.Conclusions Langerhans cell histiocytosis has characteristic skin lesions and diverse clinical manifestations.Pathology has diagnostic significance to Langerhans cell histiocytosis.Therapy strategies and curative effects are dependent on the severity of,and the organs affected by Langerhans cell histiocytosis.
