医学美学与美容医学的整体学科研究

回顾医学美学与美容医学形成独立的学科系统的十多年来的发展历程，认为这个新兴学科在“整体学科”方面还存在一些学术问题有待人们进一步探讨。并认为，所谓“整体学科研究”是遵循该学科发展的内在规律所进行的各项研究的总和，是该学科发展的灵魂。学者们的任务在于：通过“整体学科研究”寻求其学科内在规律，经一代代同道有志者坚持不懈的努力，达到学科完善的目的。     

肢体不同延长速度对局部血流量的影响

本文报告20只兔胫骨以不同速度延长时用末梢微循环测定系统动态连续监测局部血流量变化的结果,发现一次延长>1 mm时,局部肌肉血流量开始急骤下降,恢复延长前血流量所需的时间>8 h。作者认为肢体的血管、肌肉等组织对1 mm/次/d延长速度有相当大的生物适应性。延长速度>1 mm/次/d易造成局部血流量大幅度减少。延长肢肌肉萎缩、肌力减弱可能与血流量减少有关。     

A study on various symptoms of chronic hepatitis treated with radix astragali and its regulative effect to levels of serum hormone

Sixty-seven cases of chronic hepatitis were treated with Radix Astragali. After treatment (2-month course), the clinical improvement rate in 38 cases of the Stagnation of the Liver-Qi and Deficiency of the Spleen type was 92.1%, and in 26 cases of the Deficiency of Liver Yin and Kidney Yin type was 88.5%, more effective than in the control group (P<0.05). The regulative effect to the levels of serum hormone was observed in the patients of the Stagnation of the Liver-Qi and Deficiency of the Spleen type treated with this medicine. The results showed that the levels of serum triiodothyronine, estradiol (female) and testosterone (male) were increased after treatment (1.40±1.38 ng/dl, 129.30±1.23 pg/ml and 496.24±1.47 ng/dl). Pre-treatment levels were 1.22±1.49 ng/dl, 104.60±1.45 pg/ml and 398. 17±1.55 ng/dl respectively (P<0.05); however, the level of serum prolactin (2.75±4.46 ng/ml) was lower after treatment than before treatment (3.20±3.82 ng/ml,P<0.05). No obvious changes were observed in the levels of serum follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, thyroxine, triiodothyronine uptake ratio and cortisol after treatment.

Albumin recovery enhancement in membrane plasma fractionation using pulsatile flow

In therapeutic plasmapheresis using cascade filtration, it is important to maximize albumin recovery while rejecting as many gamma-globulins as possible. Several membrane fractionation techniques were investigated using fresh bovine and human plasma and cellulose acetate filters (PF 100, AKZO). In dead end mode the sieving coefficients were found to decrease as transmembrane pressure increased. This was due to membrane plugging during the course of filtration after about 20 minutes which lead to a rapid increase in transmembrane pressure. In single pass mode the albumin recovery factor generally remains around 40% since the permeate flux is much less than the inlet flow. When strong pulsations (4 to 6 Hz) were superposed on the inlet plasma flow in single pass mode, the albumin sieving coefficient remained at about 0.95 while the permeate flux was increased by 106%. As a result a recovery factor of more than 80% could be sustained for at least 90 minutes without membrane plugging. Therefore pulsatile flow plasma fractionation seems to be an interesting approach to combine continuous operation with high albumin recovery.

夜间电子生物阻抗测量装置对阴茎勃起功能障碍的检测

目的 :探讨夜间电子生物阻抗测量装置 (NEVA)在阴茎勃起功能障碍的诊断中的应用价值。方法 :对 4 1例主诉阴茎勃起功能障碍者 (障碍组 ) 19例主诉无勃起功能障碍但有射精障碍者 (无障碍组 )进行NEVA检测。结果 :障碍组夜间试验中的夜间勃起的次数、阴茎勃起的最大体积改变、最长持续时间等客观指标均要差于无障碍组 ,差异有统计学意义 (P <0 .0 1)。结论 :NEVA为非侵入性检测、可鉴别心理性阴茎勃起功能障碍和严重的器质性勃起功能障碍 ,且对勃起功能障碍的定性和定量具有一定的客观性。
