老年病人鼻饲方法的改进

目的探讨增加置管深度并抬高床头对预防老年鼻饲病人食物反流的效果。方法将 5 75例需鼻饲的卧床老年病人按鼻饲医嘱时间顺序及不平衡指数最小原则分成三组 ,分别给予教科书中的常规置管深度置管 (对照组 )、置管深度延长 10cm(观察 1组 )、置管深度延长 10cm并抬高床头 30～ 45°(观察 2组 )进行鼻饲。结果三组病人食物反流率比较 ,P <0 .0 1;观察 1、2组分别与对照组比较 ,P <0 .0 5、P <0 .0 1;观察 1组与观察 2组比较 ,P <0 .0 1。增加置管深度并抬高床头其食物反流率最低 ,仅增加置管深度次之 ,常规置管最高。结论增加置管深度并抬高床头可显著降低老年鼻饲病人食物反流发生率。     

Prolactin responses to haloperidol in drug-free and treated schizophrenic patients

Summary The prolactin response to 5 mg haloperidol i.m. was studied in 12 schizophrenic patients in a drug-free state and after a month treatment with haloperidol, as a possible index of dopamine receptor sensitivity and occupancy. Blood samples were taken at times 0, 60, 90 and 120 minutes. The increase in PRL observed in the drug-free state disappeared after drug treatment. The PRL plasma levels after treatment with 60 mg haloperidol per os were higher than the maximal PRL responses after 5 mg i.m. The increases in baseline PRL caused by the treatment correlated positively to the reduction in the BPRS score. The test was also performed in a group of 11 patients chronically treated with haloperidol during a daily dose of 60 mg, and 15 days after reduction of the dose to 30 mg. PRL increases after 5 mg haloperidol i.m. were observed only after reduction of the dose. It is suggested that the prolactin response to haloperidol is an index of the occupancy of receptors that are involved in the PRL releasing mechanisms, and could be used to verify their blockade by the neuroleptics, especially in patients that do not respond positively to drug treatment.     

老年患者静脉穿刺常见困难及对策

静脉穿刺是临床常用的护理操作技术。老年人由于各器官生理性老化 ,经常合并多种疾病 ,患病率高 ,患病时间长 ,致使静脉穿刺次数多 ,因此静脉穿刺比较困难。对临床上常遇到的静脉穿刺困难进行分析并给予相应解决方法 ,经过多年实践 ,遵照这些方法 ,穿刺成功率达 97%以上 ,为患者解除了病痛     

单纯性肥胖患儿血清载脂蛋白AI及B含量的改变

测定了３０例单纯性肥胖患儿（年龄７岁～１２岁）和３０例同龄健康儿童的血清载脂蛋白ＡＩ（ａｐｏＡＩ）、Ｂ（ａｐｏＢ）ａｐｏＢ／ａｐｏＡＩ比值，甘油三酯（ＴＧ）和总胆固醇（ＴＣ）。结果肥胖患儿组血清ａｐｏＡＩ明显低于健康儿童组，ａｐｏＢ、ａｐｏＢ／ａｐｏＡＩ、ＴＧ明显高于健康儿童组，差异均非常显著（Ｐ＜０．０１）。肥胖患儿组ＴＣ虽然高于健康儿童组，但差异不显著（Ｐ＞０．０５）。     

Ethical Issues in Psychotherapy

Abstract: The goal of psychotherapy is not only the dissolution of the symptoms, but also to attempt to bring about an improvement in adaptability and deepening the achievement of self-understanding. The nature of psychotherapy is based on the relationship between the therapist and patient. Such a goal and nature mean that some kinds of psychotherapy are beyond the medical model. In this paper ethical issues in psychotherapy are discussed as follows. 1) some complicated matters in informed-consent, 2) the hit or miss techniques of the poorly trained therapist, 3) the protection of privacy, 4) the sexual misconduct of therapists with patients, 5) special consideration for child-adolescent patients.     

老年急性心肌梗塞37例临床分析

对３７例老年急性心肌梗塞与５０例老年前期急性心肌梗塞病人进行临床对比分析．结果显示：部分老年急性心肌梗塞病人发病不典型，并发症多，死亡率高，这可能与并发室颤、房室或束支传导阻滞、心衰等有关．     

紧急纤维支气管镜在老年高危患者中的应用

A clinical and genetic study of 56 Saudi Wilson disease patients: identification of Saudi-specific mutations

Wilson disease (WD) is a hereditary disorder, with recessive transmission and genetic heterogeneity. Several mutations of ATP7B, the gene underlying WD, were reported in many ethnic groups. In this study, mutation screening in ATP7B of 56 Saudi Arabian WD patients was undertaken. The clinical data of all patients were recorded. The entire ATP7B coding sequence, including intron-exon boundaries were screened for mutation by the polymerase chain reaction (PCR)-based mutation detection technique and DNA sequencing. Thirty-nine patients were symptomatic at presentation and 17 subjects were pre-symptomatic siblings of affected patients. Fourteen patients had neurological, 11 patients had mixed (hepatic and neurological), and 14 patients had hepatic presentations. Family history suggestive of WD was present in 72% of cases and 68% had consanguineous parents. Genetic analysis showed disease-causing mutations in three exons (exons 8, 19 and 21) of the ATP7B gene in 28 patients (50%). Mutations in exons 21 (18 cases) and 19 (one case) were unique for Saudis. This large series of Saudi patients with WD has shown wide variability in the genomic substrate of WD. There is no correlation between genotype and clinical presentation.

Amputation in elderly and high-risk vascular patients

Fifty-eight patients underwent lower limb amputation for arterial disease over a 30-month period. Mean age of the patients was 72 years. Cardiopulmonary and metabolic risk factors were present in the majority of the patients. Postoperative one-year and three-year mortality rates were 24, 40, and 76%, respectively. Contralateral amputation was required in one-third of the patients after a mean period of eight months. Only younger and healthier patients returned to a meaningful social life after appropriate prosthetic fitting. In view of the high mortality and morbidity rates, above-knee amputation seems a better choice than below-knee amputation in these elderly and high-risk patients.
