髓内钉在矫治儿童成骨不全严重肢体畸形中的应用

[目的]探讨用髓内钉治疗儿童成骨不全严重肢体畸形中的矫形和防止再骨折的作用。[方法]2000年1月-2004年8月期间，共治疗8例，男3例，女5例。术中均将弯曲股骨或胫骨行多段截骨后髓内钉固定。其中2．0mm克氏针置入2例，Ender钉3例，Nancy弹性髓内钉3例。[结果]术后8例畸形改善明显，随访9个月．5a，平均2．4a，随访中肢体未再发骨折，未见髓内针合并感染、骨不连等并发症。1例术前轮椅患儿术后可扶拐行走；1例发生克氏针骨外部分断裂。[结论]多段截骨矫形后内置髓内钉治疗儿童成骨不全，对矫正肢体畸形、减少再次骨折机会，效果确实可靠。     

γ-干扰素对大鼠胚胎基底前脑及隔区核团胆碱能神经元分化的影响

为了研究γ-干扰素(IFNγ)对大鼠胚胎基底前脑及隔区核团胆碱能神经元分化的作用,采用免疫组织化学方法对胆碱能神经元的特异性标记酶-胆碱乙酰基转移酶(ChAT)进行染色,ChAT阳性细胞的数量反映了胆碱能神经元的数量,并用14C-乙酰CoA作底物来检测ChAT活性。结果显示,IFNγ处理过的实验组,ChAT阳性细胞数量显著增加,ChAT活性也增加,这种增加被大鼠抗小鼠IFNγ单克隆抗体(Ab-IFNγ)完全拮抗。采用流式细胞术对细胞周期进行分析,细胞周期及细胞百分率无明显改变。用MAP2标记神经细胞,神经细胞数基本未增加。以上结果提示:IFNγ不能促进基底前脑和隔区神经元增殖,胆碱能神经元表达增加不是因为神经元数目增加而是分化的结果。     

伊贝沙坦与雷米普利对充血性心力衰竭疗效比较

目的比较伊贝沙坦与雷米普利对充血性心力衰竭(CHF)的临床疗效及安全性。方法72例CHF患者在常规治疗基础上随机分为2组。伊贝沙坦组(36例)口服伊贝沙坦150 mg.d-1;雷米普利组(36例)口服雷米普利2.5 mg.d-1。治疗前与治疗6 mo后分别用超声心动图测量左室射血分数(LVEF)、左室短轴缩短分数(LVFS)、每搏输出量(SV)、心排量(CO)、心脏指数(CI)评估心功能。结果治疗6 mo后,2组心功能较治疗前非常明显改善(P<0.01),2组之间比较差异无统计学意义(P>0.05)。结论伊贝沙坦与雷米普利治疗CHF均有效,且疗效相当。     

Sternum insufficiency fracture presenting as acute chest pain: a case report and review of the literature.

The spine, pelvic bones and long bones of the lower extremities are common sites for insufficiency fractures. Cases of sternum insufficiency fractures have been rarely reported in an elderly patient. Insufficiency fracture tends to occur in bones with decreased mechanical strength. It tends to occur in elderly patients, especially in postmenopausal women, with underlying diseases. We describe a case of sternum insufficiency fracture in a patient with rheumatoid arthritis and systemic lupus erythematosus on long-term corticosteroid therapy diagnosed in an emergency setting. Sternum insufficiency fracture is a rare cause of chest pain. This case serves to remind the emergency physician to remain vigilant for other noncardiac and nontraumatic causes of chest pain. If diagnosed accurately, these patients can be discharged and treated as outpatients.     

论护士审美修养的条件和形式

护士的审美修养是全面提升护士自身素质的内在要求,以人的健康长寿、职业道德以及护士内在美与外在美的统一为条件.学校教育、社会教育、自然美教育、艺术美教育是其基本途径.护士审美修养贵在自觉和持之以恒.     

Evaluation of mandibular block using a standardized method.

The purpose of this prospective randomized study was to investigate the manifestations and efficiency of mandibular block (MB) using a standardized method. In this study, 123 patients requiring MB were randomly assigned to receive MB using a repeated measures design. Mandibular block was administered in each patient by using 2.1 mL of 2% lidocaine with 1:100 000 epinephrine for the inferior alveolar nerve, lingual nerve, and/or buccal nerve. Clinical parameters including the electric pulp test and test for soft tissue sensation using a sharp dental explorer were assessed on both the operated side and contralateral side before and 5, 10, and 15 minutes after injection, and at the end of surgical procedure. Results of the test of the contralateral tooth served as the control group. No response to the electric pulp test at a maximum output (80 readings) was used as the criterion for pulpal anesthesia. Results obtained with electric pulp test and sharp explorer test were not significantly different during various intervals on the contralateral side, indicating the reliability of this standardized method for assessing MB. The MB technique achieved a high rate of subjective numbness (100%) according to the perception of the patients of overall numbness and lip numbness. Overall anesthetic success rates of pulpal anesthesia were 5.7% for the central incisor, 38.2% for the canine, 55.3% for the first premolar, and 90.2% for the first molar. No significant difference was found in the efficiency of anesthesia related to sex or age of the patients. A slower onset of pulpal anesthesia after MB was found for the anterior teeth than for the posterior teeth. This study suggests that the use of a standardized method might produce a clearer and more comprehensive evaluation of the efficiency and manifestations of MB.
