注射用阿昔洛韦的质量考察

目的研究注射用阿昔洛韦的质量考察方法。方法采用家兔来检查检品中的热原,不出现干扰现象,应用鲎试剂检测内毒素出现严重干扰结果。结果注射用阿昔洛韦溶液稳定性考察结果,pH值为10.5~11.5,经放置24h后肉眼观察溶液呈澄清pH9.0,72h后呈微浊pH7.5,168h后呈沉淀。结论用细菌内毒素检查来替代热原检查,出现严重干扰现象,无法判断结果,只能用家兔法做热原检查。     

温热水刺激鼻肠管主动留置在危重患者中的应用

目的:探讨45~47 ℃温热水刺激鼻肠管主动留置在危重患者中的应用效果。方法:选取2018年12月1日~2020年1月31日在青岛市某三级甲等医院重症医学科住院需留置鼻肠管的76例患者作为研究对象,在床旁主动留置鼻肠管过程中,通过分次间断注入45~47 ℃温热水,刺激胃肠蠕动,提高鼻肠管置管成功率。结果:76例患者中,其中一次性置管成功71例,成功率为93.42%;5例一次性置管失败患者,给予再次温热水刺激置管,成功3例,剩余2例2次置管均未成功,给予被动等待技术均置管成功。结论:在重症医学科危重患者床旁主动留置鼻肠管过程中,通过注入45~47 ℃温热水刺激胃肠蠕动,能够保证置管成功率,尽快实现幽门后喂养,为危重患者早期肠内营养的实施建立有效途径。该方法操作简便,值得临床推广。     

环戊硫酮治疗干眼的临床疗效评价

Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value.
