Objective:To measure the effective optical zone (EOZ) after small incision lenticule extraction (SMILE) by using corneal topographic map and modulation transfer function (MTF), and to analyze the related factors affecting the EOZ.Methods:A retrospective observational case series study was performed.Sixty-two myopic patients (62 eyes) who underwent SMILE between December 2015 and July 2017 in Jinan Mingshui Eye Hospital were enrolled.The EOZ was measured by using tangential corneal curvature topographic map and MTF pre- and 6-month post-operatively.The repeatability of data was determined by intraclass correlation coefficient (ICC) and Cronbach Alpha coefficients; the agreement of data was identified by using Bland-Altman plot; the correlations between EOZ and surgical parameters were analyzed by utilizing Pearson correlation coefficient.This study protocol was approved by the Ethics Committee of Jinan Mingshui Eye Hospital(No.2015[013]). Written informed consent was obtained from each patient before surgery.Results:The ICC and Cronbach Alpha coefficients of EOZ measured by corneal topographic map were greater than 0.9, which showed high intraobserver repeatability.The Bland-Altman plots displayed relatively good agreement between the two methods.The 95% limits of agreement was -0.49 to 0.89 μm.Six months after SMILE, the EOZ measured by tangential corneal curvature gradient topographic map was (5.32±0.25)mm, which was (1.18±0.25)mm smaller than predicted optical zone, and the EOZ measured by MTF method was (5.07±0.32)mm, which was (0.20±0.35)mm smaller than corneal tomographic EOZ, and the difference was significant ( t=-4.487, P<0.01). A negative correlation was found between the EOZ and attempted refractive correction ( r=-0.364, P=0.004). The positive correlations were found between the EOZ and ΔKm or ΔQ 6 months after SMILE ( r=0.367, 0.514; both at P<0.01). Conclusions:The EOZ measured by tangential corneal curvature topographic map after SMILE is of high repeatability and is consistent with the result calculated by MTF method.The EOZ is significantly reduced after SMILE.

Objective To evaluate the immune reconstitution of HIV-1 infected individuals after long-term highly antiretroviral therapy (HAART). Methods Twenty-five HIV-1 infected individuals receiving HAART, 17 without HAART and 15 healthy controls were included in the study. CD4 +T, CD8 +T,CD8/human leukocyte antigen DR (HLADR) + T, CD8/CD38 +T cells, and the expression of CD127 on CD3 +T cells from peripheral blood samples were measured by flow cytometry. IL-7 in peripheral blood was measured by enzyme-linked immunosorbort assay (ELISA) in HAART group. t test was performed to compare the measurement data among the groups. Results Before HAART, the count of CD4 + T cells in HIV-1 infected group was lower than that of the healthy control (t =9. 12, P <0. 01 ), while the counts of CD8 + T,CD8/HLADR+T, and CD8/CD38 +T cells were higher than those of the healthy control (t = 4.48, 4.89 and 3.88, P<0. 01 ). Ater 7 years' antiviral therapy, CD4 +T cells increased, CD8 +T cells decreased, but both of them didn' t reach to the normal levels ( t = 2.66 and 2.43, P < 0.05 ). While the counts of CD8/HLADR+T cells and CD8/CD38 +T cells almost reached to the normal levels (t = 0. 86 and 1.39, P >0.05). Before HAART, the concentration of IL-7 in HIV-1 infected group was higher than that in healthy controls (t =5.31, P <0.01 ). It decreased with HAART, but was still higher than the normal level (t =2. 81, P < 0. 05 ). The expression of CD127 on CD3 + CD8 + T cells in non-HAART group was significantly lower than that in healthy control ( t =- 6.01, P < 0.01 ), while that in HAART group was higher ( t = 2.32,P <0.05), but still not reached to the normal level ( t = 4.49, P < 0. 05 ). CD127 expression on ( CD45RA + ) CD3 + CD8 + T cells almost increased to the normal level ( t= 0. 28, P > 0. 05 ), while that on ( CD45RO + ) CD3 + CD8 + T cells was still remarkably lower than the normal ( t = 4. 86, P < 0. 05 ). Conclusion Long-term HAART can partially restore the count and function of lymphocyte subsets in HIV-1 infected individuals, and the abnormal immune activation can be inhibited.

Objective To investigate the functional changes of dendritic cells (DC) in elderly patients with sepsis. Method Elderly patients (n = 20), ages 75 to 86 years, treated in the department of internal medicine for cadres and the medical intensive care unit (MICU), were selected to participate in the study. Patients with ma-ligoant tumors, hematological diseases, immune diseases, or a history of receiving drugs known to interfere with immune functions were excluded. Using the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) definition of sepsis, the patients were categorized into four groups: non-sepsis (group A) (n = 5) ; sepsis (group B) (n = 5) ; severe sepsis (group C) (n = 5) ; and septic shock (group D) (n = 5). The peripheral blood mononuclear cells (PBMCs) of each patient were isolated and cultured with human re-combinant granuloceyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in vitro for 10 days. The cells were examined under an inverted microscope, scanning electron microscopy, and flow cytometry. The MTT colorimetric assay was used to observe the abilities of the dendritic cells to stimulale an allogeneic T lym-phocyte response in vitro. Paired t -test was used to compare changes in the surface markers among the different groups, Results The PBMCs in the four groups of patients differentiated into cells with typical dendritic configura-tions after in vitro cuhure with combined cytokines. The CD40, CD80, CD86, and HLA-DR expressions on the cell surfaces increased after culture,with (43.2±12.5)%/(27.3±9.3)%, (31.4 ± 10.1)%/(22.5 ± 8.7)%, (39.3±15.7)%/(21.9±7.7)%, and (75.4±25.6)%/(58.7±16.7)%, respectively. The stimulation index (the abilities of the dendritic cells to stimulale the allogeneic T lymphocyte response in vitro) in the four groups of patients after culture were (23.3±7.9) in group A, (18.9±8.3) in group B,(11.4±5.1) in Group C,and (5.5 ± 3.7) in Group D. Conclusions The immune functions of the dendritic cells of elderly patients with sepsis decrease in a linear manner with the severity of their septic state.
