Root avulsion of brachial plexus in infants and children.

Twenty-one patients, under 6 years of age, with root avulsion of the brachial plexus were treated from 1975 to 1987. Among them, 9 had root avulsion of the upper trunk, 2 root avulsion of the lower trunk with middle trunk broken, and 10 root avulsion of the whole brachial plexus. Follow-up of 16 patients showed excellent results in 2 patients, good in 11, fair in 1 and poor in 2. It is suggested that good results can be obtained if multi-paired nerve transfer is adopted in treatment. We conclude that owing to anatomical and physiological characteristics of the respiratory system in children, it is harmful to perform phrenic nerve transfer concomitantly with intercostal nerve transfer. Advisably, two-stage operation is required, otherwise dyspnea and pneumonia are liable to occur. In addition, the time of the operation could be extended to 4-5 years after injury in children, but best results are obtained if the operation is performed within 1 year.

     

猪全肠外营养模型

白色杂种猪 19只 ,体重 2 2 .3± 2 .4 kg,经皮颈总静脉穿刺前腔静脉置管 ,其中 14只动物完成 2 8d全肠外营养 ( TPN)。 14只动物 ,共施行置管 2 9次 (平均 1.31± 0 .86次 ) ,成功率为10 0 %。再次置管的原因为导管脱出 ( 7/ 2 9)和导管栓塞 ( 2 / 2 9) ,本研究还对与腔静脉置管相关静脉进行了解剖     

非程控降温,—80℃冻存自体外周血干细胞的研究

目的：观察非程控降温、－80℃冻存的方法对自体外周血十细胞（APBSC）的保存效果。方法：以6％羟乙基淀粉（HES）、5％二甲基亚砜（DMSO）及4％人血白蛋白（ALB）的混合物为冷冻防护剂，将APBSC直接置于－80℃下保存，冻存前反复苏后测定APBSC的CFU－GM、BFU－E；观察移植后造血功能重建情况。结果：13例患者白细胞在十3～＋7天下降至（0．0～0．1）×10／L，白细胞（0．0～0．2）×109／L持续时间3～6天，于＋9～＋11天恢复至1．0X109／L以上．中性粒细胞绝对值（ANC）于＋9～＋11天达到0．5X109／L。血小板在＋3～＋7天下降至（2．0～21）×109／L，于＋8～＋15天恢复至20×109／L以上。CFU－GM、BFU－E回大率分别为76．5％、78．4％。结论：非程控降温、－80℃冻存是一简便、经济、有效的自体外周血于细胞保存方法。     

THE BASIC CHARACTERISTICS OF THE NUCLEOTIDE SEQUENCE OF 5S RIBOSOMAL RNA FROM THE HUMAN WORM PARASITE FASCIOLOPSIS BUSKI

With the method of rapid gel sequencing, the complete nueleotide sequence of Fasciolopsis buski 5S rRNA has been determined: AAC GGG AUG AAG CUA GAC AUG UGG CGG CCU AGU UGG AGG UCG GAA CUC GGA AGU UAA GGA AUG UUG GGC CUG GUU AGU ACU GGU AUG GGU GAC CUU GGG AAU ACC GGG UGU UGC GUC CA_(OH) This have been compared with 553 species of other organisms 5S rRNA sequences previously published and fitted to a secondary structural model.     

Clinical analysis of 107 cases with chemical burns

From 1978 to 1987 107 cases of chemical burns were treated. The patients were mainly young and middle age people (83.08%), with mean burned areas 17.8%. The majority of involved parts were low extremities. 57.44% of burned eyes became blind. Mean days in hospital were 43 days. Cure rate was 98.13% and death rate 1.87%. We emphasized that burned wounds must instantly be washed down with water, intoxication resulting from chemical matters must be effectively treated. Diagnosis of depth of burned wound by acids and means of prevention of chemical burns were also discussed.     

蒲黄对大白鼠心律失常的预防作用

蒲黄水提物腹腔注射(5g生药/kg)大白鼠,预防异丙肾上腺素引起的心室纤颤和猝死,以及氯化钡恒速灌注引起的心律失常,结果表明蒲黄水提物能显著地提高动物的存活率,并明显地增加导至动物心律失常而致死的氯化钡剂量。
