??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.     

老年慢性支气管炎合并Ⅱ型呼吸衰竭采用有创-无创序贯机械通气治疗的效果及安全性观察

目的:探讨无创-有创序贯机械通气治疗老年慢性支气管炎合并Ⅱ型呼吸衰竭的临床疗效。方法:随机将2014年1月～2017年3月收治的74例老年慢性支气管炎合并Ⅱ型呼吸衰竭患者分为两组,A组采用有创机械通气治疗,B组采用有创-无创序贯机械通气治疗,比较两组的临床疗效。结果:B组治疗后的呼吸频率、SaO_2、PaCO_2、PaO_2、有创通气时间、总通气时间、住院时间、再插管率、VAP率与院内死亡率明显少于A组,组间比较差异有统计学意义(P0.05)。结论:有创-无创序贯机械通气治疗老年慢性支气管炎合并Ⅱ型呼吸衰竭,能有效改善患者的呼吸通气功能,缩短其治疗及住院时间,且治疗安全,更适合用于临床推广。     

可溶性髓样细胞触发受体-1在化脓性关节炎诊断及疗效评价分析

目的分析可溶性髓样细胞触发受体-1(sTREM-1)在化脓性关节炎诊断及疗效评价中的价值,为感染性疾病诊断和治疗工作提供研究依据。方法选取2015年2月-2017年2月医院收治的50例化脓性关节炎患者作为化脓性关节炎组,选取同期35例单纯骨关节炎患者作为骨关节炎组,选取同期30名健康体检者作为对照组。检测研究对象血液中sTREM-1、C-反应蛋白(CRP)、红细胞沉降率(ESR)水平,对化脓性关节炎组和骨关节炎组患者关节液中sTREM-1水平进行检测和比较;分析患者sTREM-1、CRP及ESR水平在化脓性关节炎诊断中的价值,观察化脓性关节炎组患者的临床疗效。结果三组研究对象血液sTREM-1水平、血液CRP水平、ESR水平比较差异有统计学意义(P<0.05),其中化脓性关节炎组患者指标水平最高;化脓性关节炎组患者关节液sTREM-1水平为(82.05±62.97)ng/L高于骨关节炎组的(43.36±7.48)ng/L,两组比较差异有统计学意义(t=9.628,P<0.001);关节液sTREM-1、血液sTREM-1、CRP水平诊断化脓性关节炎患者的受试者工作特征曲线下面积(AUC)分别为0.913、0.841、0.785;关节液sTREM-1水平较低的化脓性关节炎患者的疗效分布优于关节液sTREM-1水平较高的患者(Z=2.260,P=0.024)。结论化脓性关节炎表现为关节液和血液sTREM-1表达水平的上调,可作为诊断化脓性关节炎的辅助指导,术前检测关节液sTREM-1水平也有助于预测手术治疗的效果。     

降钙素原和Th1/Th2比值对结直肠癌患者术后感染性并发症的诊断价值

目的探讨降钙素原(PCT)和辅助性T细胞(Th)Th1/Th2比值对结直肠癌患者术后发生感染性并发症的诊断价值。方法选取2015年1月-2017年12月医院收治的95例结直肠癌术后合并感染性并发症患者为感染组,95例术后未发生感染性并发症的结直肠癌患者为对照组。收集两组患者术前1 d、术后3 d、7 d晨起空腹外周血,采用全自动血液细胞分析仪检测白细胞(WBC)计数,采用酶联免疫吸附测定(ELISA)试验检测血清PCT水平,采用流式细胞术检测外周血Th1、Th2细胞含量及Th1/Th2比值,应用受试者工作特征(ROC)曲线分析WBC、PCT和Th1/Th2比值对结直肠癌患者术后发生感染性并发症的诊断价值。结果术后3 d、7 d,感染组患者血清PCT水平、外周血Th2细胞含量、WBC计数均高于对照组,Th1/Th2比值低于对照组(P<0.05); ROC曲线显示,术后3 d、7 d,PCT、Th1/Th2比值诊断结直肠癌患者术后发生感染性并发症的AUC均>0.80。PCT联合Th1/Th2比值诊断结直肠癌患者术后发生感染性并发症的敏感性和特异性与指标单独诊断相近。结论 PCT和Th1/Th2比值是早期诊断结直肠癌患者术后发生感染性并发症的快速、可靠指标。
