8-(N,N-二甲基-胺甲基)-黄芩苷对非白假丝酵母的抑菌作用

目的探索分析8-(N,N-二甲基-胺甲基)-黄芩苷抗非白假丝酵母的作用,拓宽其应用范围。方法将近平滑假丝酵母、克柔假丝酵母、光滑假丝酵母的标准菌株及临床菌株选为待试菌株,测定8-(N,N-二甲基-胺甲基)-黄芩苷、黄芩苷及伊曲康唑对待试菌株的抑菌圈直径。结果除伊曲康唑对部分待试菌株耐药外,3种药物对待试菌株存在一定的抗菌作用。8-(N,N-二甲基-胺甲基)-黄芩苷对近平滑假丝酵母标准菌株、近平滑假丝酵母临床菌株、克柔假丝酵母临床菌株的抑菌圈直径分别为(29.44±5.27)mm、28.00(25.00,30.00)mm、18.00(15.00,24.00)mm,大于黄芩苷;对光滑假丝酵母临床菌株的抑菌圈直径为25.00(20.00,28.00)mm,大于伊曲康唑(P<0.05)。其对光滑假丝酵母的标准菌株、临床菌株的抑菌圈直径分别为(25.56±4.64)mm、25.00(20.00,28.00)mm,小于黄芩苷;对克柔假丝酵母的标准菌株、临床菌株的抑菌圈直径分别为(18.89±3.33)mm、18.00(15.00,24.00)mm,小于伊曲康唑(P<0.05)。结论 8-(N,N-二甲基-胺甲基)-黄芩苷对近平滑假丝酵母标准菌株、近平滑假丝酵母临床菌株、克柔假丝酵母临床菌株的抗菌作用优于黄芩苷,对光滑假丝酵母临床菌株的抗菌作用优于伊曲康唑;其对光滑假丝酵母的标准菌株、临床菌株的抗菌作用弱于黄芩苷,对克柔假丝酵母的标准菌株、临床菌株的抗菌作用弱于伊曲康唑。

??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。     

降钙素原、超敏C-反应蛋白和白细胞介素6对导管相关血流感染早期诊断的价值分析

目的:研究分析降钙素原(PCT)、超敏C-反应蛋白(hs-CRP)和白细胞介素6对导管相关血流感染早期诊断的价值。方法:观察组为住院接受治疗的导管相关血流感染患者148例,对照组为健康者,共140例。为上述观察对象开展PCT、hs-CRP和白细胞介素6检测,对单一检测以及联合检测的导管相关血流感染检出率进行比较。此外比较两组观察对象的PCT水平、hs-CRP水平和白细胞介素6水平。结果:联合检测的导管相关血流感染检出率明显高于单一检测,差异有统计学意义(P<0.05);观察组患者的PCT水平明显较对照组高,其hs-CRP水平以及白细胞介素6水平亦高于对照组,差异有统计学意义(P<0.05)。结论:PCT、hs-CRP和白细胞介素6诊断导管相关血流感染的价值较高,值得临床广泛应用。
