云南省乳腺癌生存情况的种族差异

目的 探讨种族因素在妇女乳腺癌中的预后价值。方法 把1990～1999年间的6771例原发性乳腺癌患分成汉族组和少数民族组，进行包括年龄、TNM分期、雌激素受体(ER)和孕激素受体(PR)表达情况、组织学类型、月经情况和生存期的单因素和多因素分析。结果 少数民族组乳腺癌的死亡风险较汉族组高，在确诊时的平均年龄更小，TNM分期更高，ER、PR表达阳性率低，更多的人处于绝经前期，更易患分化低且易转移的髓样癌、硬癌和炎性癌。结论 在现今社会经济状况下，种族可以作为判断乳腺癌预后的独立的指标。

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.     

卡维地洛治疗充血性心力衰竭疗效及安全性观察

目的：观察卡维地洛治疗慢性充血性心力衰竭(CHF)患者的临床疗效及其不良反应。方法：10例CHF患者，在接受常规利尿剂、血管紧张素转换酶抑制剂(ACEI)、洋地黄等治疗，病情基本稳定的基础上，给予卡维地洛治疗，从小剂量(3．125mg，2次／d)开始，逐渐增加剂量，终点剂量50mg／d(25mg，2次／d)，疗程6个月，观察治疗前后症状、体征、心功能(NYHA)分级、心衰评分、实验室检查的变化及不良反应。结果：与治疗前相比，治疗6个月后，CHF患者的症状、体征、心功能分级、心衰评分均有明显改善。无肝、肾功能损害，不良反应少，且有相当部分患者能耐受终点剂量。结论：卡维地洛治疗CHF能明显改善心功能，不良反应少，耐受性好。
