社区高血压管理中的健康教育效果评价

目的探讨健康教育在高血压药物治疗中的作用及对患者生活质量的影响。方法将社区筛查中发现的高血压患者共计137例,根据高血压危险度进行分层,随机分为综合治疗组和单一用药组。结果一年后,综合治疗组血压控制理想,总有效率为91.2%,单一用药组总有效率为76.8%,两组有统计学差异(P<0.01);两组间的危险度等级分层有统计学差异(P<0.01);综合治疗组的生活方式及精神状态明显好于单一用药组。结论健康教育有利于社区高血压的治疗,并能提高患者生活质量。     

深圳市宝安区居民结核病防治知识知晓率调查

目的了解深圳市宝安区居民对结核病防治知识的掌握情况,探索存在的问题和解决措施。方法采取分层随机抽样的方法,同一时间分别对辖区10条街道,每条街道15~20名居民进行结核病知识的问卷调查。结果共收回问卷180份,其中有效问卷171份(95%)。结核病相关知识知晓率为72.4%,被调查对象以青壮年为主,性别、婚姻状况对结核病相关知识知晓率无明显影响,不同的文化程度其相关知识知晓率有显著性差异(P<0.05);结核病特定知识知晓率为56.1%;结核病传播方式知晓率为81.3%;减免政策和专业机构知晓率为49.2%。结论人群的结核病防治知识掌握情况不容乐观,应根据实际情况,对健康教育的形式和内容进行调整,有针对性地开展健康教育。     

在美欧非洲用中医治疗HIV、AIDS的体会

中医药具有纯天然、很少毒副作用和抗药性,并价廉适应面广特点,据笔者近10多年在美欧非洲几十个国家和地区的千余例HIV、AIDS病人的临床实践证实,中医中药、针灸对治疗HIV、AIDS疗效显著。     

Hyperglycemia, hyperlipemia, and periodic paralysis: a case report of new side effects of clozapine

1. 1. This case report of a Chinese male schizophrenic patient describes new side effects that have not been documented previously for patients treated with clozapine. At certain doses of clozapine, the patient showed direct adverse reactions, which include a combination of hyperglycemia, hyperlipemia, and periodic paralysis.

2. 2. In a four-year study of this patient who had no previous episodes of diabetes in his or his family history, the authors found that these symptoms disappeared upon withdrawal of clozapine and relapsed with re-treatment of the drug.

3. 3. This study indicates that hyperglycemia, hyperlipemia, and periodic paralysis may need to be monitored on patients treated with clozapine.

     

Vitapex糊剂在儿童年轻恒牙根尖诱导成形术中的应用

目的探讨Vitapex糊剂和氢氧化钙糊剂用于儿童年轻恒牙根尖诱导成形术的治疗效果。方法对85例儿童,98颗牙根尖发育未完成,牙髓病变已波及根髓、牙髓已坏死或并发根尖周炎的年轻恒牙分为2组,分别用Vitapex糊剂和氢氧化钙糊剂进行根尖诱导成形术,观察其根尖发育情况。结果Vitapex糊剂组总有效率为91.84%。氢氧化钙组总有效率为77.55%。2者疗效在统计学比较存在显著性。结论Vitapex糊剂作为一种根尖诱导成形剂具有良好的治疗效果。值得在临床推广应用。     

Spontaneous rupture of the patellar and contralateral quadriceps tendons associated with secondary hyperparathyroidism in a patient receiving long-term dialysis.

Although spontaneous rupture of the extensor tendon of the knee is more likely to occur in uremic patients with secondary hyperparathyroidism, simultaneous ruptures of bilateral knee extensor tendons is a rarely reported condition. We describe a 30-year-old man with uremia who underwent subtotal parathyroidectomy because of secondary hyperparathyroidism with very high serum parathyroid hormone (PTH) level (1940.4 pg/mL). Two weeks later, he complained of a sharp pain in both knees without trauma when he walked downstairs with his left knee forward and right knee behind. Spontaneous simultaneous ruptures of the right patellar tendon and the left quadriceps tendon were diagnosed and surgically repaired. The mechanism of spontaneous tendon rupture in uremic patients with secondary hyperparathyroidism seems to be related to high PTH level which results in osteolytic bone resorption at the tendon insertion site. Early surgical repair, control of secondary hyperparathyroidism, early use of vitamin D analogs, and total parathyroidectomy with or without autotransplantation of part of the parathyroid gland, can treat and prevent tendon rupture or re-rupture with satisfactory results.     

耶鲁抽动症整体严重度量表对抽动障碍患儿的临床评估

A novel system for simultaneous monitoring of locomotor and sound activities in animals

This paper describes a PC-based system for simultaneous monitoring of locomotor and sound activities on small rodents. The displacement and location signals of the animal were first determined across consecutive video-frames, followed by marked data reduction to cater for long-term studies. At the same time, sounds generated by the animal were detected and the sound level was recorded as root-mean-square values at 1 s intervals. Preliminary data showed that such a multi-parametric monitor system could provide comprehensive information on the animal's activity.
