Objective:To determine whether laser in situ keratomileusis(LASIK) affects the central 30-degree visual field.Methods:This clinical trial comprised 31 patients(61 eyes)scheduled to have LASIK for myopia or myopic astigmatism.Automated static perimetry was performed before and 1 week,6 months after the surgery using the Octopus 1-2-3 perimetry.The main outcome measures were the meao sensitivity(MS) change in the central 15-degree visual field and the MS change in the 15-to 30-degree visual field.The preoperative and postoperative MS values were calculated,and the difference between them(delta MS) was determined.Statistical analysis were performed by SPSS12.0 using the randomized complete block design ANOVA(two factors analysis of variance).Differences among variables were evaluated by q-test. Results:One week after the operation,all uncorrected visual acuity equal to or better than 4.7.Six months after operation,visual acuity distributed between 4.9 and 5.2. There was no significant change in the central 15-degree visual field MS,neither 1 week nor 1 month after the operation;between 15 and 30 degrees,there was a statistically significant decrease.One week after the operation,the delta MS value was(-0.91?1.42)dB(mean?standard deviation);6 month after the operation,the delta MS value was(-0.87?1.38)dB. Conclusion:Automatic static perimetry can detect decreased sensitivity in the 15-to 30-degree visual field after myopic LASIK.It may be a useful quantitative subjective test for measuring the vision quality after refractive surgery in future.

Purpose To explore the effects of progesterone receptor isoforms A and B ( PR-A,PR-B) on carcinogenesis and progres-sion of ovarian serous cystadenocarcinoma ( OSC) . Methods The expressions of PR-A and PR-B in 52 cases of OSC, 22 cases of o-varian borderline serous cystadenoma ( OBSC) , 22 cases of umbrella of normal fallopian ( UNF) were detected by immunohistochmical Elivision technique. Results The expression of PR-A in OSCs, OBSCs and UNFs were 94. 5%, 94. 5%, and 68. 38%, respective-ly, with there were statistical significance among three groups (P<0. 05). The expression of PR-B in OSCs, OBSCs and UNFs were 100%, 77. 27%, and 40. 38%, respectively, with there were statistical significance among three groups (P<0. 05). The difference of PR-A/PR-B ratio in OSCs, OBSCs and UNFs was statistical significance ( P<0. 05 ) . The expressions of PR-A and PR-B in OSCs were lower, there were statistical significance between the clinical stageⅠ+Ⅱ andⅢ+Ⅳ (P<0. 05), and histological gradeⅠandⅡ. The difference of PR-A/PR-B ratio between the histological gradeⅠandⅡin OSC was statistical significance. There was statistical significance of PR-B between OSCs with lymph metastasis and without lymph metastasis (P<0. 05). Expression of PR-A and PR-B in OSC was positive correlation (P<0. 05). Conclusion With the carcinogenesis and progression of OSC, the expressions of PR-A and PR-B gradually declined, and the downregulation of PR-B is more obvious, may be an important biological sign of malignant transfor-mation in ovarian tissue. The increasing ratio of PR-A to PR-B in OSC may indicate poor differentiation. The relatively higher expres-sion of PR-B may inhibit the lymph metastasis in OSC.

BACKGROUND: 5-azacytidine (5-Aza) has been frequently used to induce bone marrow mesenchymal stem cells (BMSCs)differentiation into cardiomyocyte.OBJECTIVE: To observe expression of cardiomyocyte-related receptors in cardiomyogenic differentiation of rat BMSCs.METHODS: BMSCs of passage three were assigned to four groups: group Ⅰ: L-DMEM solution alone was replaced; Ⅱ:L-DMEM solution was replaced after induction of 100 mg/L AST+5 μmol/L 5-Aza for 24 hours; group Ⅲ: L-DMEM solution wasreplaced after induction of 10 μmol/L 5-Aza for 24 hours; and group Ⅳ: L-DMEM solution was replaced after induction of 5 μmol/L5-Aza for 24 hours. Culture medium was replaced every 3 days in each group. Differentiated cells were identified after 30 days ofinduction.RESULTS AND CONCLUSION: Expression of cardiomyocyte specific proteins Nkx2.5, cTnT and Desmin was detected in groupsⅢ, Ⅳ and Ⅱ after induction compared with group Ⅰ , with significant differences (P < 0.01). The amount of cTnT and Desminexpression expression was significantly higher in groups Ⅱ and Ⅲ compared with group Ⅳ (P < 0.01). The level of Nkx2.5expression was significantly higher in groups Ⅱ (P < 0.01) and Ⅲ (P < 0.05) compared with group Ⅳ. No Nkx2.5, cTnT andDesmin espression was detected in group Ⅰ. After induction for 2 weeks, cells with spontaneous contractility were observed ingroups Ⅱ and Ⅲ, indicating differentiation towards cardiomyocyte after induction. Results demonstrated that induction effectswere similar between 100 mg/L AST+5 μmol/L 5-Aza and 10 μmol/L 5-Aza. This may contribute to cytoprotective effects of AST,which can promote vascular endothelial cell proliferation, enhance celss tolerance to 5-Aza-induced cytotoxicity and upregulatecardiac-specific protein expression.

Objective To study the effect of the treatment of epiglottis cyst by Nd:YAG laser combined with clamp under electronic laryngoscope. Methods Under superficial anesthesia, ninety cases of epiglottis cyst complicated with a series of pharyngeal clinical symptoms which were treated by Nd:YAG laser combined with clamp guided under electronic laryngoscope. Results Eight patients were not reexamined, and the rest 82 patients were followed up after one month, the body sensation and laryngeal obstruction disappeared or relieved signiifcantly. After further conifrmation by laryngoscope, the cysts of 79 cases were disappeared, and 3 cases were considered residual, the cysts was clamped out and treated by biopsy forceps Laser, further checked after 2 months by laryngoscope, the cysts disappeared! 100%recovered. Conclusion Treatment of epiglottis cyst by Nd:YAG laser combined with clamp under electronic laryngoscope has many advantages such as clear vision, accurate positioning, less hemorrhage, less postoperative complications, less recurrence rate and less pain. Treatment is effective and worthy of clinical promotion.

Programmed death-1(PD-1)is a major co-suppression receptor expressed on T cells.Binding with its ligands (PD-L1 and PD-L2),PD-1 can inhibit T cell proliferation,activation and cytokine secretion.In normal organs,PD-1 /PD-Ls signaling pathway plays an important role in maintaining immune tolerance,while during tumorigenesis,it can suppress T cell immune response and promote tumor immune escape.This article reviewed the research progress on PD-1 /PD-Ls signaling pathway,comprised of structure and expression of PD-1 /PD-Ls, mechanism of the signaling pathway,as well as the expression characteristics of soluble form of PD-1 /PD-L1 (sPD-1 /sPD-L1),and summarized the categories of anti-PD-1 /PD-Ls antibodies and their clinical trials in canc-er immunotherapy.

Objective To analyse the correlation between cytotoxic T-lymphocyte antigen-4(CTLA-4)gene polymorphism-318 T/C ,CT60 G/A and the susceptibility of hepatocellular carcinoma (HCC) .Methods Totally 277 cases of HCC and 306 healthy controls in our hospital from September 2012 to September 2014 were selected as the research subjects ,all subjects were Han nationality .The peripheral blood (5 mL) in each case was collected for separating serum ,the AFP level was detected by chemilunescent method ,the serum IL-2 ,IL-4 and TGF-β levels were detected by ELISA .Genomic DNA was extracted ,after PCR amplification ,the CTLA-4-318 T/C ,CT60 G/A gene polymorphism distributions were detected by the direct sequencing method . Results The CTLA-4-318 CC and CT60 AA genotypes all conformed to the Hardy-Weinberg equilibrium(P> 0 .05) .CTLA-4-318 CC and CT60 AA were related with the HCC risk decrease ,different genotypes of CTLA-4 CT60 G/A had obvious relation with serum AFP level(χ2 =12 .779 ,P=0 .012) .The serum IL-2 and IL-4 levels in the HCC patients carrying CTLA-4-318 T and CT60 G allele were significantly decreased ,while the TGF-βlevel was significantly increased ,moreover CTLA-4-318 had obvious relation with the HCC grading .Conclusion CTLA-4-318 TT could promote the occurrence and progression of HCC ,which might be related with the down-regulation of Th1/Th2 type cytokines ,and up-regulation of Th3 type cytokine .
