我国日间手术开展现状与前景展望

日间手术在国外已有上百年的发展历史，现已成为欧美国家重要手术模式。我国于20世纪初开始开展日间手术，但目前尚未普及，发展不平衡问题比较突出，存在认识不清、开展不规范、与医保支付对接不畅等问题。日间手术是一种使国家、医院和病人三方均受益的新型手术模式。近年来，国家相关管理部门积极引导，开展日间手术的医院明显增多，可以预见，我国日间手术即将进入快速发展的新阶段。因此，有条件的医院可以从简单、易操作的病种开始，落实临床路径，积累经验，再逐步稳妥展开。在保证质量的前提下，不断拓展日间手术范围，提高三、四级手术比例。同时，积极与医保支付政策对接，采取灵活的方式，获得医保的支持，更好地促进我国日间手术的快速发展。     

Low bone mineral density in ambulatory persons with cerebral palsy? A systematic review

Purpose: Non-ambulatory persons with cerebral palsy are prone to low bone mineral density. In ambulatory persons with cerebral palsy, bone mineral density deficits are expected to be small or absent, but a consensus conclusion is lacking. In this systematic review bone mineral density in ambulatory persons with cerebral palsy (Gross Motor Function Classification Scales I–III) was studied.

Materials and methods: Medline, Embase, and Web of Science were searched. According to international guidelines, low bone mineral density was defined as Z-score?≤??2.0. In addition, we focused on Z-score?≤??1.0 because this may indicate a tendency towards low bone mineral density.

Results: We included 16 studies, comprising 465 patients aged 1–65?years. Moderate and conflicting evidence for low bone mineral density (Z-score?≤??2.0) was found for several body parts (total proximal femur, total body, distal femur, lumbar spine) in children with Gross Motor Function Classification Scales II and III. We found no evidence for low bone mineral density in children with Gross Motor Function Classification Scale I or adults, although there was a tendency towards low bone mineral density (Z-score?≤??1.0) for several body parts.

Conclusions: Although more high-quality research is needed, results indicate that deficits in bone mineral density are not restricted to non-ambulatory people with cerebral palsy.

• Implications for Rehabilitation

• Although more high-quality research is needed, including adults and fracture risk assessment, the current study indicates that deficits in bone mineral density are not restricted to non-ambulatory people with CP.

• Health care professionals should be aware that optimal nutrition, supplements on indication, and an active lifestyle, preferably with weight-bearing activities, are important in ambulatory people with CP, also from a bone quality point-of-view.

• If indicated, medication and fall prevention training should be prescribed.

常规应用螺内酯联合依那普利治疗老年扩张型心肌病心力衰竭

目的评价螺内酯联合依那普利治疗老年人扩张型心肌病（DCM）心力衰竭的有效性和安全性。方法以148例老年DCM心力衰竭患者作研究对象,按随机化原则分为观察组（74例）和对照组（74例）。对照组为依那普利,加上基础用药（地高辛、双氢克尿噻）;观察组为对照组用药加上螺内酯。治疗6周后复查两组的动态心电图、超声心动图。结果治疗后两组的左室射血分数（LVEF）均有增加,左室收缩末期容积（LVESV）和左室舒张末期容积（LVEDV）均有减少,24 h室性早搏（VA）数也均有减少;观察组与对照组比较,LVEF显著增加。两组均未发现高血钾及肝肾功能损害。结论在老年DCM心力衰竭常规用药的基础上,常规加用螺内酯联合依那普利的治疗有效、安全,可显著改善左室重构和防治猝死。     

Loss of the nocturnal dip and increased variability of blood pressure in normotensive patients with noninsulin-dependent diabetes mellitus

Summary. Eleven normotensive diabetics with noninsulin-dependent diabetes mellitus (NIDDM) (mean age 52.5 SD 8.2 years) and 11 controls (mean age 47.4 SD 8.9 years) had their ambulatory blood pressure and heart rate recorded non-invasively by the Oxford Medilog System in standard hospital conditions. The results were averaged as hourly means of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), and heart rate (HR) for the 24-h period and similarly for the ‘awake’ period (14.16 h) and the ‘asleep’ period (8–10 h). Hourly means for diabetics and controls showed no differences in blood pressure and heart rate over the 24 h. During sleep, control subjects showed a significant drop in SBP (P < 0.001), DBP (P < 0.001), MAP (P < 0.001) and HR (P < 0.001). However, this nocturnal dip in blood pressure could not be demonstrated in the diabetic group. Blood pressure variability was significantly increased in diabetics compared to controls during waking hours (P < 0.01). These results indicate that in noninsulin-dependent diabetics during sleep there is loss of the nocturnal dip of BP seen in normal subjects, and they have increased BP variability. These may be contributing factors to the development of hypertension and the accelerated target organ damage (TOD) seen in diabetes.,     

Ambulatory monitoring of ultraviolet erythema in photosensitive subjects

Little is known about whether patients with photosensitive disorders exhibit a different ultraviolet erythema time course from subjects with a normal response to sunlight. We have described the application of an instrument for ambulatory monitoring of the development of ultraviolet erythema by a reflectance method in a group of patients with chronic actinic dermatitis (CAD) and in a group of normal subjects. Investigations of the time course have been reported previously but the techniques used relied upon manual measurement. Consequently sampling frequencies have been considerably lower than the one-minute sample rate used here. We have not demonstrated any difference in the rate at which erythema develops and peaks between patients with CAD and subjects with a normal response to sunlight.

贝那普利降压疗效与校正QT间期的关系

目的探讨原发性高血压患者心电图心率校正QT间期(QTc)和贝那普利降压疗效之间的关系.方法采用前瞻性队列研究方法调查安徽A县899名高血压病患者的基线心电图、治疗15 d前后的血压变化及相关临床和流行病学特点等情况.结果 QTc和血压下降呈负相关.QTc每增加0.1秒1/2,收缩压和舒张压的下降值分别减少3.6 mmHg和3.3 mmHg,且差异均有显著性(P＜0.05).将QTc三等分后,随着QTc等分的增加,收缩压和舒张压的下降值均逐渐减少,且差异具有显著性(P＜0.05);将QTc等分后的变量放入方程中进行趋势性分析,发现在收缩压和舒张压组中的负相关关系具有显著性(P＜0.05).随着QTc等级的增加,舒张压有效率逐渐降低,且有显著性差异(P＜0.05),收缩压的效应关系不如舒张压明显.结论 QTc和贝那普利降压疗效呈负相关,对贝那普利短期降压疗效具有重要的预测价值.     

Low-density lipoprotein subfraction profiles in dialysis patients

Summary: Uraemic dyslipidaemia is a major risk factor for cardiovascular disease in end-stage renal failure patients. In patients without renal failure, high levels and qualitative abnormalities of low-density lipoprotein (LDL) are known to be atherogenic. Recently, LDL subfraction analysis has associated premature coronary artery disease with a high prevalence of small, dense LDL particles characterizing the LDL subclass phenotype B. We therefore examined the lipid profiles, LDL subfraction distribution and phenotypes in our population of haemodialysis (HD; n = 30) and peritoneal dialysis patients (PD; n = 17), and compared them to 40 asymptomatic, non-uraemic volunteers. Dialysis patients had significantly higher triglyceride and VLDL cholesterol concentrations and lower HDL cholesterol and smaller LDL peak particle diameters. PD patients had significantly higher total cholesterol, glycated haemoglobin and fasting blood glucose levels with smaller LDL peak particle diameters (24.4 [0.1] vs 24.8 [0.1 nm] than HD. Both groups showed significant negative correlations between plasma triglyceride and LDL peak particle diameter, and positive correlations between HDL cholesterol and LDL peak particle diameter. All the PD patients expressed the B phenotype (LDL peak diameter ± 25.5 nm) compared to 73% of HD patients. This study demonstrates that HD and especially PD patients have atherogenic lipid profiles which are associated with a predominance of small dense LDL particles and the highly atherogenic LDL subclass phenotype B.
