针刺对海洛因依赖的脱毒疗效及其防复吸潜力的临床研究

目的 比较针刺、针刺加阿片、阿片加丁丙诺啡及阿片加韩氏戒毒仪4种方法的脱毒疗效及其对脱毒末期稽延性戒断症状和心理渴求的影响。方法 应用戒断症状量表观察脱毒疗效，应用视觉类比量表(VAS)研究心理渴求程度。结果 针刺改善海洛困依赖者戒断症状的优势主要表现在治疗的第6天以后，改善渴求心理的优势表现在第8天以后，且无明显副作用。结论 针刺具有防复吸潜力。可作为解决稽延性戒断症状和消除心理依赖的治疗方法。     

不同频率电针刺激对大鼠髌腱血流量变化的影响

目的:探讨分析不同频率电针治疗时肌腱血流的变化及其变化机制。方法:将40只Wistar大鼠分为2Hz组、10Hz组、100Hz组和针刺(10Hz)+阿托品组、针刺(10Hz)+酚妥拉明组。手术剥离出大鼠胫骨粗隆上缘的髌腱,利用超声测定技术,观察针刺足三里和梁丘穴前后髌腱血流量的变化。并采用静脉滴入阿托品和酚妥拉明的方法,对针刺作用机制进行分析。结果:(1)2Hz组和10Hz组在针刺过程中,髌骨腱血流量分别下降至针刺前的82.11±10.8%、49.17±11.63%,针刺停止后,两组血流量却逆转为高于针刺前的水平,以10Hz组上升幅度较为明显;(2)100Hz组针刺过程中,血流量下降至针刺前的37.54±12.79%,针刺停止后血流量未恢复到针刺前的水平;(3)针刺(10Hz)+阿托品组:针刺时血流量降低至44.61±12.01%,停针后血流量未出现增加现象;(4)针刺(10Hz)+酚妥拉明组:针刺时血流量增加至119.73±14.66%,针刺停止后血流量继续增加。结论:(1)电针刺激期间髌腱血流下降,刺激停止后血流量明显增加;(2)中、低频率刺激对血流量增加效果优于高频刺激;(3)针刺对血流量的影响与舒血管神经和缩血管神经的调节有关。     

肺心病慢性呼吸性酸中毒合并代谢性酸碱失衡判断方法探讨(附80例次血气分析)

目的：对42例肺心病慢性呼吸性酸中毒患者的80例次血气测定结果。方法：用不同的酸碱图（卡）及代偿公式进行酸碱类型的初步差别分析。结果：结合临床表现、各种影响因素与治疗反应等作出综合判定。结论：比较二种判定的差异，并提出较为实用、可靠的判断建议，以助于复合型呼吸性酸碱失衡的临床诊断与处理。

电针对大鼠脑局部缺血-再灌流损伤的保护作用

再灌流前电针“环跳”穴３０ｍｉｎ，观察对左大脑中动脉（ＭＣＡ）缺血 再灌流模型大鼠早期运动功能、自由基代谢、脑水肿及神经电生理活动的影响。结果：缺血再灌＋针刺组大鼠再灌流后神经功能缺损状况有较明显的改善，病灶侧脑组织过氧化物歧化酶（ＳＯＤ）活性及丙二醛（ＭＤＡ）含量恢复到接近假手术对照组的水平。皮层体感诱发电位（ＳＥＰ）测量表明缺血侧Ｐ１潜伏期及Ｐ１ Ｎ１波幅亦有显著性改善。结果表明：于再灌流前电针处理对本模型脑缺血 再灌流损伤有保护作用     

Renal acid excretion in early infancy

In early infancy, complex disorders of acid base metabolism are more frequent than in any other age group, with a predisposition to metabolic acidosis due to an age-related low renal capacity for acid excretion and an unphysiologically high actual renal acid load in nutrition with common formulas. Recently in preterm and small-for-gestational-age infants, persistent maximum renal net acid excretion (NAE) with subnormal or normal blood acid base status, impaired weight gain, and adaptive hormonal reactions have been observed. Incipient late metabolic acidosis is one example of a mixed disorder of acid base metabolism with maximum renal NAE in early infancy. Alkali therapy is highly effective and can be realized both on an individual basis, using urine pH screening as a diagnostic criterium for maximum renal acid stimulation, or on a general preventive level using modified standard formula with a reduced actual renal NAE similar to that seen on alimentation with human milk. From an integrated point of view, the low glomerular filtration rate and renal capacity for acid excretion beyond the developmental age of more than 44 weeks, may well be interpreted as the result of a specific adaptation to breast feeding sparing energy, and thus an evolutionary advantage for the survival of mother and child.

双音节普通话言语测听词表的等价性评估

目的：本项研究针对已编制完成的具有语音平衡特性的双音节普通话测听词汇表（MSTM）进行难度等价性分析，以期挑选出具有难度一致性的一组词表应用于临床。方法：对10张（每张50词）的双音节词表进行数字化录音。选取65名年龄18～25岁具有大专以上文化程度，日常生活中以普通话为交流方式的听力正常人作为受试者。对5名受试者进行预试验，获得正式测试时所需的给声强度。对60名受试者进行正式的言语识别测试，使用SPSS11．0软件对结果进行等价性分析。结果：10张双音节测试词表中，除测试表5外，其余各表间均具有难度等价性。结论：9张双音节普通话测听词汇表具有较好的难度等价性，可应用于临床测试和实验研究中。     

Cholinergic balance in dementia with Lewy bodies: reversible worsening of Parkinsonism at rivastigmine dosage modulation

We describe a patient with probable dementia with Lewy bodies (DLB) whose Parkinsonism worsened after administration of rivastigmine within the therapeutic dose range. Some extrapyramidal signs (EPS) then reversed to pre-treatment level after rivastigmine dose reduction. We draw attention to the need of EPS monitoring during titration of cholinesterase inhibitors in patients with DLB. This is the first report to our knowledge of iatrogenic worsening of Parkinsonism which was successfully managed by dose reduction.

Sommario Si descrive il caso di un paziente affetto da Demenza a corpi di Lewy (Dementia with Lewy Bodies, DLB) probabile, in cui si è assistito ad un peggioramento del parkinsonismo dopo somministrazione di rivastigmina a dosi terapeutiche. Alcuni segni extrapiramidali sono regrediti al livello pre-trattamento con una riduzione posologica di rivastigmina. Si sottolinea la necessità di un monitoraggio dei segni extrapiramidali durante la titolazione della terapia con inibitori dell’acetilcolinesterasi cerebrale in pazienti con DLB. Questo è il primo caso descritto, a nostra conoscenza, di un peggioramento iatrogeno di parkinsonismo efficacemente gestito con una riduzione posologica della terapia con rivastigmina.
