Objective To analysis the distribution of posterior corneal astigmatism (PA) and evaluate the influence of keratometric astigmatism (KA) and total corneal astigmatism (TCA) on the calculation of Toric intraocular lens (Toric IOL) in patients with age-related cataract (ARC) and high corneal astigmatism.Methods An observational study design was adopted.Pentacam was used to measure 200 eyes of 181 patients with ARC and KA＞0.75 D in Affiliated Hospital of Nantong University from August 2016 to April 2017.KA,PA,TCA and anterior corneal astigmatism (AA) were recorded.The astigmatism magnitude and axis of PA was studied.The subjects were divided into astigmatism with the rule group,astigmatism against the rule group and oblique astigmatism group according to the axis of AA.The correlations of decomposition values between PA and AA or KA and TCA in each group were analyzed by Pearson linear correlation analysis.The difference of decomposition values between KA and TCA in each group was compared by paired sample t test.The type and axis of Toric IOL were calculated by online formula according to KA and TCA.This study followed the Declaration of Helsinki and written informed consent was obtained from each patient prior to any medical examination.Results The mean astigmatic magnitudes of PA was -0.32 D×93.1°.PA exceeded 0.5 D in 22 eyes (11％).The steepest posterior corneal meridian was vertically aligned in 163 eyes (81.5％).The decomposition value KP(0) and KP (45) of PA were positively correlated with those ofAA (r=0.480,P＜0.001;r=0.251,P＜0.001).The mean astigmatic magnitudes of KA and TCA were 1.44D×89.6° and 1.32 D×89.5° in astigmatism with the rule group,1.39 D×153.4° and 1.71 D×154.4° in astigmatism against the rule group and 1.13 D× 122.0° and 1.24 D× 124.2° in oblique astigmatism group.53 eyes (69.7％) had KA higher than TCA in astigmatism with the rule group.82 eyes (87.3％) had KA lower than TCA in astigmatism against the rule group;20 eyes (66.7％) had KA lower than TCA in oblique astigmatism group.There were significant differences in KP (0) between KA and TCA in different astigmatism groups (all at P＜0.001).The calculated Toric IOL type were inconsistent in 85 eyes(42.5％) and the calculated axis were inconsistent in 176 eye s (88.2％).Conclusions In patients with high corneal astigmatism,the astigmatism type of PA is mostly astigmatism against the rule.Ignoring the PA can lead to deviation of Toric IOL type selection and axis placement in some patients.For patients who cannot measure PA or TCA,the type of Toric IOL should be adjusted appropriately.

Immune checkpoint inhibitors are commonly used in clinical practice and have achieved good efficacy, but immune-related adverse events (irAEs) are often unpredictable and may lead to serious clinical consequences. Risk factors for irAEs include gender, body mass index, tumor class, drug type, pre-existing autoimmune disease, and tumor mutational burden; predictors are mainly immune cells, cytokines and chemokines, autoantibodies, genome, and gut microbes. By further investigating the mechanisms, risk factors and predictors for the occurrence of irAEs, guidance for the clinical prediction and management of irAEs is supposed to be provided.

Objective To investigate the syndrome differentiation characteristics of children with atopic dermatitis(AD)and the immune imbalance status in children with different syndrome types of AD.Methods A total of 159 AD children and 100 normal control children were enrolled.The peripheral blood eosinophil(Eo)count was measured by impedance method,total serum immunoglobulin E(IgE)by immunoturbidimetric assay,and interferon-gamma(IFN-γ),interleukin-4(IL-4),interleukin-5(IL-5)and interleukin-17(IL-17)were measured by multiple microspheres flow immunofluorescence assay.Results Among 159 AD children,syndrome of heart-fire and spleen-deficiency was most commom,accounting for 38.4%,followed by syndrome of blood-deficiency and wind-dryness(22.0%),syndrome of heat accumulation in heart and spleen(20.1%)and syndrome of spleen-deficiency and dampness-accumulation(19.5%).Compared with normal control group,there was no significant difference in serum IFN-γ level among different syndrome types of AD.The levels of peripheral blood Eo,serum total IgE,IL-4 and IL-17 in AD with heart-fire and spleen-deficiency syndrome were significantly increased(P<0.05).The levels of peripheral blood Eo,IL-4,IL-5 and IL-17 in AD with blood-deficiency and wind-dryness syndrome were significantly increased(P<0.05).The levels of IL-4,IL-5 and IL-17 in AD with heat accumulation in heart and spleen syndrome were significantly increased(P<0.05).The levels of peripheral blood Eo and serum IL-4 in AD with spleen-deficiency and dampness-accumulation syndrome were significantly increased(P<0.05).Conclusion Heart-fire and spleen-deficiency syndrome is the most common type in children with AD,however,the main type under 3 years old is heat accumulation in heart and spleen syndrome.Th2/Th17 immune imbalance are the main pathogenesis in heart-fire and spleen-deficiency syndrome,blood-deficiency and wind-dryness syndrome and heat accumulation in heart and spleen syndrome,and Th2 immune imbalance is the main pathogenesis of spleen-deficiency and dampness-accumulation syndrome.

Objective:To investigate the relationship between serum matrix metalloproteinase-9 (MMP-9) level and the location and severity of bleeding in patients with cerebral microbleeds(CMBs).Methods:A total of 60 CMBs patients admitted to the Department of Neurology of the First Affiliated Hospital of the Xinxiang Medical University from January 2019 to August 2020 were selected as subjects as the CMBs group, and 60 healthy controls without nervous system diseases in outpatient physical examination during the same period were selected as the control group. The clinical data and biochemical indicators of the two groups were collected. Serum MMP-9 levels were measured by enzyme linked immunosorbent assay (ELISA). According to susceptibility weighted imaging (SWI), CMBs patients were divided into grade 1 group ( n=24), grade 2 group ( n=19) and grade 3 group ( n=17), and according to the micro analytical rating scale (MARS), the CMBs patients were divided into the lobar group ( n=19), the deep or infratentorial group ( n=17) and the mixed group ( n=24).The relationship between serum MMP-9 level and the location and severity of CMBs was analyzed. SPSS 19.0 software was used for data statistical analysis.One-way ANOVA, t-test and rank sum test were used for comparison. Logistic regression analysis was used to analyze the influencing factors. Pearson correlation analysis and Spearman correlation analysis were used for correlation analysis. Results:The level of MMP-9 in CMBs group was significantly higher than that in control group (208.13(142.25, 285.88) μg/L, 149.50(93.40, 186.51)μg/L), and the difference was statistically significant ( P<0.05). Serum MMP-9 level was a risk factor of CMBs ( β=1.322, OR=3.750, 95% CI=2.038-7.997, P=0.002). The difference of level of MMP-9 in different severity of CMBs was statistically significant (147.55(109.25, 266.47)μg/L, 242.12(147.55, 288.80)μg/L, 270.42(203.43, 364.27)μg/L, P=0.017). Serum MMP-9 level was positively correlated with the number of CMBs ( r=0.371, P=0.003). The difference of MMP-9 level of CMBs in different locations were statistically significant (249.77(158.43, 338.46)μg/L, 188.83(138.52, 243.15)μg/L, 210.65(144.25, 255.78)μg/L, P=0.013). The increased serum MMP-9 level was a risk factor for CMBs( β=0.401, OR=1.122, 95% CI=1.004-1.204, P=0.036). Conclusion:The increased level of serum MMP-9 may be a risk factor of CMBs, especially for CMBs in cerebral lobesand, and the level of MMP-9 is positively correlated with the severity of CMBs.
