??Objective    To discuss the influence of basic periodontal therapy on the level of IL-8?? IL-10 in serum and gingival crevicular fluid in patients who have chronic periodontitis complicated by coronary heart disease. Methods     A total of 65 cases of patients with chronic periodontitis complicated by coronary heart disease were selected and divided into two groups randomly??Group A of 35 patients who received the basic periodontal therapy and cardiac medical treatment??Group B of 30 patients who received cardiological treatment only. Then??select 25 patient who had developed chronic severe periodontitis with non-systematic disease to establish group C and give them the basic periodontal therapy only. Observe the changes of the IL-8??IL-10 levels in serum and gingival crevicular fluid and the periodontal infection indexes??BI??PD??. Results    The results showed that after three months of basic periodontal therapy the periodontal clinical indices of both group A and group C became better and the IL-8 level obviously reduced??while the IL-10 level obviously increased. There was no obvious difference between group A and group B in each examination index before the therapy. After three months??we found that the periodontal infection index??SBI PD??of group A was obviously better than group B. Compared to group B??the IL-8 level of group A obviously reduced??and the IL-10 level obviously increased. The difference was statistically significant??P < 0.05??. Conclusion    The basic periodontal therapy can effectively improve periodontal conditions of the patients with chronic periodontal diseases??and reduce the risk of breaking the normal cardiovascular function.     

Interleukin-11 Overexpression and M2 Macrophage Density are Associated with Angiogenic Activity in Proliferative Diabetic Retinopathy

ABSTRACT

Purpose

To investigate the expression of IL-11 and its receptor IL-11Rα and to quantify density of CD163⁺ M2 macrophages in proliferative diabetic retinopathy (PDR).     

A Very Long-term Longitudinal Study on the Evolution and Clinical Outcomes of Persistent Iatrogenic Atrial Septal Defect After Cryoballoon Ablation

Background

Persistent iatrogenic atrial septal defect (iASD) is a common but poorly characterized complication after cryoballoon (CB) pulmonary vein isolation (PVI) procedures. We therefore investigate its prevalence, evolution, risk factors, and clinical outcomes in a prospective longitudinal study.

Minimum clinically important difference of the health-related quality of life scales in adult spinal deformity calculated by latent class analysis: is it appropriate to use the same values for surgical and nonsurgical patients?

BACKGROUND CONTEXT

Health-related quality of life (HRQOL) parameters have been shown to be reliable and valid in patients with adult spinal deformity (ASD). Minimum clinically important difference (MCID) has become increasingly important to clinicians in evaluating patients with a threshold of improvement that is clinically relevant.

灯盏乙素介入IP3R-Ca2+途径抑制β淀粉样蛋白诱导的神经细胞凋亡

目的：观察灯盏乙素（Scu）对β淀粉样蛋白（Aβ）诱导的细胞模型中1，4，5-三磷酸肌醇受体（IP₃R）-Ca²⁺途径的影响，探讨其在阿尔茨海默病（AD）病程中可能发挥的积极作用。方法：选用神经母细胞瘤细胞分为对照组、Scu处理组、Aβ处理组、Aβ+Scu （高、中、低）处理组及Aβ+IP₃R拮抗剂组，用CCK-8法筛选药物浓度并检测各组细胞生存率；用酶联免疫吸附法检测各组细胞中1，4，5-三磷酸肌醇（IP₃）的含量；用蛋白印迹和实时荧光定量聚合酶链反应方法检测各组细胞IP₃R和凋亡相关因子Caspase-3、Bcl-2、Bax的蛋白及mRNA的表达水平；用激光共聚焦显微镜观察各组细胞内Ca²⁺浓度的变化；用AnnexinV/PI双染法测定各组细胞的凋亡率。结果：与对照组和Scu处理组相比，Aβ处理组细胞存活率下降，IP₃含量升高，IP₃R、Bax和Caspase-3的蛋白及mRNA表达上调，Bcl-2蛋白及mRNA的表达下调，细胞胞浆内Ca²⁺浓度及细胞凋亡率升高；Aβ+Scu处理组细胞中各检测指标的变化与Aβ处理组的结果正好相反，IP₃R通道下游指标的变化与Aβ+IP₃R拮抗剂组基本一致。结论：Scu能够下调通路蛋白IP₃、IP₃R的表达，抑制Aβ介导的Ca²⁺内流所致的细胞凋亡，可能通过对IP₃R-Ca²⁺途径的调控来影响AD病程。     

IgE-mediated regulation of IL-10 and type I IFN enhances rhinovirus-induced Th2 differentiation by primary human monocytes

Rhinovirus (RV) infections are linked to the development and exacerbation of allergic diseases including allergic asthma. IgE, another contributor to atopic disease pathogenesis, has been shown to regulate DC antiviral functions and influence T cell priming by monocytes. We previously demonstrated that IgE-mediated stimulation of monocytes alters multiple cellular functions including cytokine secretion, phagocytosis, and influenza-induced Th1 development. In this study, we investigate the effects of IgE-mediated stimulation on monocyte-driven, RV-induced T cell development utilizing primary human monocyte-T cell co-cultures. We demonstrate that IgE crosslinking of RV-exposed monocytes enhances monocyte-driven Th2 differentiation. This increase in RV-induced Th2 development was regulated by IgE-mediated inhibition of virus-induced type I IFN and induction of IL-10. These findings suggest an additional mechanism by which two clinically significant risk factors for allergic disease exacerbations—IgE-mediated stimulation and rhinovirus infection—may synergistically promote Th2 differentiation and allergic inflammation.
