结合PNF的关节松动术(MWP)技术治疗肘关节功能障碍初探

目的:利用结合神经肌肉促进技术(PNF)的关节松动术(Mobilization with PNF,MWP)技术治疗肘关节骨折术后功能障碍,探讨其对关节主/被动活动度、疼痛、肌肉力量和本体感觉的影响。方法:取2009年8月～2012年4月本院肘关节骨折术后功能障碍患者共32例。患者术后病情稳定,视内固定牢固程度开始康复训练。分为实验组和对照组,对照组患者先常规治疗、关节松动技术、关节牵伸治疗和一般性肌力训练。实验组在以上治疗中,追加MWP治疗替换关节松动术,分别治疗8周后进行功能评价。结果:治疗前后对比,实验组、对照组在关节活动度、视觉模拟(VAS)评分、各肌群肌力方面有明显差异(P<0.01),实验组在位置觉、被动运动觉上有明显差异(P<0.01);治疗后,实验组与对照组在关节活动度、伸肌肌力和旋前肌力上有明显差异(P<0.05),尤其是在屈曲角度、主动旋前角度、VAS评分、位置觉、被动运动觉上差异明显(P<0.01)。结论:MWP对肘关节功能障碍治疗有明显疗效,对肘关节主/被动关节活动度、肌肉力量、本体感觉和疼痛缓解都有促进作用,并优于单纯使用关节松动技术的传统治疗方法。     

A Case of Cardiac Dysfunction Associated with Monoclonal Gammopathy of Undetermined Significance

The monoclonal gammopathies (MG) are monoclonal neoplasms related to each other by virtue of their development from common progenitors in the B lymphocyte lineage. Cardiac dysfunction in patients with MG is not well established. We experienced a case of cardiac dysfunction associated with MG identified by echocardiography and biopsy. Fifty nine year-old man was admitted because of dyspnea for several months. Echocardiography revealed diastolic dysfunction showing restrictive physiology with elevated left ventricular filling pressure. Bone marrow (BM) studies and immunoelectrophoresis were compatible with monoclonal gammopathy of undetermined significance. Endomyocardial, BM, and enteral biopsies for ruling out for amyloidosis (Congo-red stain) were negative. This is the case of non-amyloidotic light chain deposition cardiomyopathy.     

四磨汤口服液对胃肠运动功能障碍模型大鼠胃残留、小肠推进率及结肠P物质的影响

目的：观察四磨汤口服液对胃肠运动功能障碍模型大鼠胃残留率、小肠推进率及结肠P物质（SP）的影响．方法：6f）只大鼠随机分为空白组,模型组,四磨汤口服液高、中、低剂量组以及西药组,按夹尾法配合饥饱失常法造模后给予相应药物灌胃,检测半固体营养糊在体内的胃残留率和小肠推进率,按免疫组化要求染色并观察sP的阳性面积。结果：与空白组比较,模型组大鼠胃残留率明显升高以及小肠推进率显著降低（P〈0．05）;四磨汤口服液高剂量组较模型组大鼠胃残留率降低、小肠推进率增加（P〈0．05）;模型组结肠SP表达水平较空白组显著降低（P〈0.05）;四磨汤口服液高剂量组与西药组结肠SP阳性表达均较模型组增高（P〈0．05）。结论：夹尾法配合不规则喂养可导致大鼠胃肠运动紊乱,四磨汤口服液能促进胃肠运动障碍模型大鼠胃肠蠕动功能的恢复,能够增高胃肠功能障碍大鼠兴奋性神经递质SP的表达,可能是其调整胃肠运动功能障碍的作用机制之一。     

Prevalence of Signs of Temporomandibular Joint Dysfunction in Asymptomatic Edentulous Subjects: A Cross-Sectional Study

Patients having complete dentures with reduced vertical dimension generally do not manifest Temporomandibular Joint problems. It is not understood as to why the closure of jaws in dentulous individuals can predispose to Temporomandibular Joint problems, while the same etiology in edentulous subjects does not cause any concern. This study was planned to find out the prevalence of various Temporomandibular Joint dysfunction signs in subjects who were edentulous for a period of 6 months to 2 year. The various signs were obtained from a population of 100 healthy asymptomatic edentulous subjects by a questionnaire and then were clinically examined for the presence or absence of signs of Temporomandibular Joint dysfunction. 59% of the subjects exhibited one or more signs of Temporomandibular Joint dysfunction, 41% of the subjects did not show any signs of Temporomandibular Joint dysfunction. 56.6% of males reported signs of Temporomandibular Joint dysfunction when compared with females which was 62.5%. 43.3% of males did not show any signs of Temporomandibular Joint dysfunction when compared with those of the females which was 37.5%. The number of subjects who showed two signs was 29%, subjects who had only one sign was 25%. It was found that dysfunction was prevalent among both men and women in more than half of the asymptomatic subjects examined. 59% had one or as many as three signs of Temporomandibular dysfunction. The most commonly seen Joint dysfunction was the joint sounds which was 47%

本研究以综述的形式讨论目前MODS诊断、发病机制和治疗领域的某些研究进展。     

免疫调理联合谷氨酰胺治疗多器官功能障碍综合征的临床研究

目的通过实施免疫刺激治疗和抗炎治疗,同时联合应用谷氨酰胺治疗,观察其对多器官功能障碍综合征的治疗效果。方法采用前瞻、随机、对照的研究方法,将患者分为常规治疗组（A组）和谷氨酰胺联合免疫调理治疗组（B组）,观察单核细胞CD14HLA-DR、IL-6、IL-10、CD4／CD8和C-反应蛋白的变化,并统计两组治疗的病死率。结果A组和B组患者血浆单核细胞CD14HLA-DR、CD4／CD8、IL-6、IL-10和C-反应蛋白的水平明显高于C组（P〈0．05）。B组与A组相比,CD14HLA-DR、CD4／CD8的表达水平均明显提高（P〈0．05）;IL-6、IL-10水平、CRP和病死率明显下降（P〈0．05）。结论联合免疫调理治疗及谷氨酰胺治疗能改善MODS患者的免疫麻痹状态,下调炎症反应,提高MODS患者的治愈率。     

冠状动脉微血管内皮细胞功能障碍分子机制的研究进展

冠状动脉微血管疾病是多种心血管事件发生的高风险因素,因其病因较为复杂且具有一定隐蔽性,导致现阶段针对其病机机制仍较为有限。在冠状动脉微血管内皮细胞（CMEC）功能障碍的发生及发展的过程中,CMEC损伤是导致其发生的主要核心环节,CMEC的代谢能力、应激能力以及炎症等相关功能均与CMEC功能障碍疾病密切相关,同时也是其发生早期的主要临床特征。由于现阶段关于CMEC损伤的相关病理机制尚未完全明确,基于此,本研究对CMEC功能障碍的相关病理机制加以综述,以期为临床医护人员对该病发生的复杂病理机制更好理解,从而为后续相关研究的进展提供一定参考依据。     

Sexuality and quality of life of patients with schizophrenia

Patients with schizophrenia continue to have sexual lives despite the nature of their illness. Sexuality, sexual relationships and sexual functioning are all important quality-of-life issues for these patients. Clinicians should be aware of this and not be hesitant to inquire as to the patient's experience and functioning in these areas. The importance of the patient's sexual life should be reflected in our quality of life questionnaires, and be incorporated as part of psychiatric rehabilitation programs through formal sex education.
