Methods The rabbit model of CPB and DHCA was established by using in vivo cerebral microdialysis.

The escalation was higher in DHCA group than CPB group ( P < 0.01).

DHCA组在恢复循环早期明显升高（P<0.05），升高程度DHCA组明显高于CPB组（P<0.01）。

Use the improved "four-vessel method" to produce global cerebral ischemia model of DHCA rates.

采用改良的四血管法制作DHCA大鼠全脑缺血模型。

The Effects of Different Protective Methods with DHCA to the Concentration of Neuron Dissociative Calcium

不同脑保护方法对神经元钙离子浓度的影响

The clinical application of DHCA in neonates and infants with complex congenital heart disease

深低温停循环在新生儿及婴儿复杂先心病手术中的应用

Group I ( DHCA group): regular CPB with temperature reduced to 20 ℃, then circulation is arrested for 45 min and 90 min respectively.

组Ⅰ（单纯深低温停循环组）体外循环降温至肛温20℃时停循环45min、90min。

It was concluded that the disease was resulted from lower DHCC content in serum, which was caused by the disfunction of the kidney, so the vitamine D can not be converted into DHCC.

由此认为，乳牛骨代谢病是由肾功能障碍致维生素D转变为DHCC过程受阻，使DHCC含量降低引起的。

With this method, the serum levels of DHCC in healthy youth, patients with congenital rickets and puberty rickets and cow with renal osteomalacia were measured.

检测了先天性佝偻病、青春期佝偻病病人及患肾性骨病奶牛等血清DHCC水平。

Study on Measurement of Serum 1,25-Dihydroxy Chole-calciferol ( DHCC) and the Mechanism of the Osseous Metabolism Disease

骨代谢病乳牛血中1，25－二羟胆钙化醇（DHCC）含量的测定及发病机理研究

Results The liver size, internal, echogenicity, portal venous emboli and clinical pictures were characteristic in DHCC.

结果肝脏大小、肝内回声、门脉癌栓及其它临床特征在弥漫性肝癌中具有特征性改变。

Conclusions A lot of informations obtained from ultrasonography in DHCC have obvious diagnostic value.

结论超声对弥漫性肝癌的诊断具有重要价值。

Experimental Studies on DHCC Metabolite Determined by the Fluorimetric Method

荧光法测定DHCC代谢物的实验研究

The glucose level and serum insulin level were significantly elevated ( P < 0.05) after 1 year ′ s treatment with oral DHCT, but no further elevation was observed after 2 and 3 years ′ treatment.

并发现口服DHCT1年后高血压病患者的血糖及血清胰岛素水平均较治疗前显著升高（P＜0.05）。

The Clinical Curative Effect of Benazepril Plus Less Dosage of Dihydrochlorothiazide ( DHCT) in Treating Hypertension

贝那普利加小剂量氢氯噻嗪治疗高血压病的临床疗效

The mechanism of the eletrochemiluminescence of DHDS is discussed and the method is applied to detect the content of DHDS in tablets.

研究了DHDS的发光机理并应用本方法测定了某些降血压药中DHDS的含量。

Methods: 93 patients suffering from vascular dementia were randomly divided into three groups, the combination of intravascular He-Ne laser irradiation with electroacupuncture group ( 31 cases) and the medicine group ( dihydroergotoxine, DHET, 31 cases).

方法：将93例VD患者按区组随机法分为激光合电针组、电针组和药物组（氢化麦角碱，DHET），每组31例。

It indicates that electroacupuncture can promote the ability of learning and memory and enhance AChE activity of brain in rats of vascular dementia, and the therapeutic effect of electroacupuncture is better than that of DHET.

而电针组又高于药物组（P<0.05），说明电针能改善VD大鼠学习记忆能力，提高脑AChE的含量并使之重新分布，其作用优于DHET。

Conclusions It indicates that electroacupuncture therapy can promote the ability of learning and memorizing and enhance the content of AchE in the brain of VD. Its therapeutic effect is better than DHET. 〔

结论电针能改善VD大鼠学习记忆能力，提高脑AchE含量并使之重新分布，其作用优于DHET。

Objective: To assess the efficacy of dihydroergotoxine ( DHET) in treatment of vascular dementia ( VD).

目的：观察氢化麦角碱（DHET）治疗脑血管性痴呆（VD）的临床疗效。
