骨肿瘤患者术前术后的临床护理

骨肿瘤是众多肿瘤范畴的一个种类，因其具有肿瘤的多种性，又具骨肿瘤的特异性，据临床诊断分为良性、恶性两大类。外科手术是首选治疗方式。因为患者手术前后病情变化大，心理发生改变，所以精心护理十分重要。笔者就近年来经X线片、CT片及手术证实骨肿瘤患者的临床治疗护理观察体会进行初步介绍。     

胰岛素泵强化治疗糖尿病患者的护理

2型糖尿病即非胰岛素依赖型糖尿病，随着病情的发展，有1／3的病人最终需要外源性胰岛素来调整血糖。对患者来说，了解胰岛素对控制病情所起的作用，学会自己使用胰岛素泵是一件重要的事情。胰岛素泵能模拟人体胰腺分泌胰岛素，全天24h微量持续地释放胰岛素，从而把各时段血糖控制在理想范围，能降低并发症的发病率。我科对16例糖尿病患者进行强化治疗，取得了较好的疗效，现将胰岛素泵使用护理体会报告如下。[第一段]     

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.     

口服用维生素B_(12)

在英国和北美,标准教科书规定,用以治疗恶性贫血的维生素B_(12),都必须经注射的途径。但在瑞典,有40%的病人却是通过口服用维生素B_(12)来达治疗目的的。在美国,也正在应用这方法来治疗。口服治疗     

诱导型一氧化氮合酶在前列腺增生组织中表达的研究

目的：探讨诱导型一氧化氮合酶(iNOS)与前列腺增生(BPH)病理生理变化的关系。方法:用免疫组化法检测10例正常和30例有膀胱出口梗阻的BPH患者膀胱和前列腺组织中iNOS的表达。结果：BPH组前列腺组织中iNOS呈阳性染色，主要分布于前列腺的上皮细胞及上皮下组织中，间质平滑肌组织中均为阴性；对照组的膀胱壁、膀胱颈部和前列腺组织中均无iNOS阳性染色。结论：iNOS仅在BPH患者前列腺组织中有特异性表达，提示它参与了前列腺增生的病理生理过程。     

电针心经对心肌缺血性家兔心力环面积的影响

以心力环面积为指标，静脉滴注垂体后叶素造成家兔心肌缺血动物模型，结果表明，电针心经地心脏功能的调节作用比电针肺经显著，有相对特异性，说明心经作为一条经脉，与心脏机能活动有密切关系。     

SRY基因诊断在临床中的应用

应用聚合酶链式反应（ＰＣＲ）扩增技术，对１０例染色体核型为４６，ＸＹ和１例为４６，ＸＸ／４６，ＸＹ的性反转、睾丸女性化、两性畸形及男性生殖器发育不良的患者进行了性别决定区（ＳＲＹ）基因检测。结果表明９例４６，ＸＹ和１例４６，ＸＸ／４６，ＸＹ患者的ＳＲＹ基因存在，１例４６，ＸＹ女性患者的ＳＲＹ基因缺失。该结果表明能够用分子生物学技术对性反转、性发育异常的病因进行分析
