套管针连续臂丛阻滞行断指(肢)再植手术35例 总被引:4,自引:1,他引:3
0 引言 臂丛阻滞是上肢手术常用的麻醉方法[1].但这种阻滞方法作用时间短,对于较长时间的上肢手术,因反复穿刺而造成局部损伤较大,神经损伤率增高,患者痛苦增加.断指(肢)再植手术[1]是上肢手术中时间较长者,要求阻滞作用完善.为探讨一种阻滞时间灵活、损伤小、作用确切的麻醉方法,我们受连续硬膜外麻醉的启发[1],摸索出连续臂丛阻滞方法,现介绍如下.1 对象和方法1.1 对象 急诊断指(肢)再植手术35(男28,女7)例,年龄18岁~47岁,均因锐器伤而造成指体离断和上肢远端离断,其中1指离断5例,… 相似文献

Relationship between HLA-DRB1 and DQ alleles and the genetic susceptibility to type 1 diabetes 总被引:6,自引:0,他引:6
Objective To study the relationship between human leukocyte antigen (HLA)-DRB1 and DQ alleles and the genetic susceptibility of type 1 diabetes in North Chinese children. Methods Polymerase chain reaction (PCR) techniques were used to amplify the second exon of DRB1 and DQ alleles, after which sequence specific olignucleotide probe (SSOP) dot blot hybridization techniques were used to analyze the amplified products. Results DRB1*0301, DQA1*0301, DQB1*0201 alleles and DRB1*0301-DQA1*0501-DQB1*0201 haplotype were significantly increased in patients, while DQA1*0103 and DQB1*0601 alleles were significantly increased in controls. The distribution of DR4 and DR9 haplotypes in patients and controls were not significantly different, but DR3/DR4 and DR4/DR9 heterozygotes were significantly increased in patients. Conclusions DRB1*0301, DQA1*0301 and DQB1*0201 confer susceptibility while DQA1*0103 and DQB1*0601 confer protection to type 1 diabetes. DRB1*0301-DQA1*0501-DQB1*0201 haplotype offers a predisposition to type 1 diabetes in North Chinese. Although the distribution of DR4 and DR9 in patients and controls had no significant difference, DR3/DR4 and DR3/DR9 heterozygotes were significantly increased in patients, showing that the susceptive effects of DR3 and DR4 or DR4 and DR9 haplotypes could be added up. 相似文献

去氢紫堇碱对兔血小板TXB2及主动脉6-keto-PGF1PGF1α含量的影响 总被引:1,自引:0,他引:1
Dehydrocorydaline (DHC) was shown to reduce the production of thromboxane B2 (TXB2)in platelets and 6-keto-prostaglandin F1α (6-keto-PGF1α in the aorta of rabbits in vitro. The effect of DHC increased with the increase of dose.DHC 0.41 mg was found to inhibit the formatiom of TXB2 markedly while not reduce the content of 6-keto-FCF1α. DHC also exhibited obvious inhibitory effect on the arachidonic acid (0.66mmol/L) induced formation of platelet malondialdehyde (MDA). These effects were similiar to the specific cycloxygenase inhibitor, aspirin (0.03 mg/ml). The results suggest that (1) DHC reduced both contents of TXA2 and PGI2 in vitro. (2) DHC markedly inhibited the system of cycloxygenase in cell microsomes. (3) As to whether TXA2 synthetase or cycloxygenase was inhibited in these experiments is still to be elucidated. 相似文献

BACKGROUND: To evaluate the efficacy and toxicity of cisplatin/etoposide
continuous infusion chemotherapy for cancer of unknown primary site in
Taiwan, a region with a high prevalence of endemic viral infections.
METHOD: Between April 1994 and February 1996, 20 patients with a diagnosis
of CUPS were treated, including 15 males and five females, of average age
63.3 years (range 41-83 years). Continuous intravenous infusion of
etoposide 80 mg/m2 and cisplatin 25 mg/m2 was given for 3 days every 3
weeks. Pretreatment tumor marker and viral serology studies were performed
for baseline evaluation. Nearly two-thirds of the patients had poorly
differentiated carcinoma. The average number of metastatic sites was 2.65
(range 1-4), with liver and lymph node involvement predominating. RESULTS:
The overall response rate was 25% (95% CI 17.7-32.3%); 30.7% for poorly
differentiated cancers and 25% for well differentiated cancers. Median
survival was 4 months (range 1-12 months), 4.8 months for patients
attaining partial response. Toxicity was moderate, grade 3 and 4
neutropenia occurred in 55% and grade 3 and 4 thrombocytopenia in 40%;
other toxicities were mild. CA125 and CA199 were elevated in more than 50%
of patients. Viral serology studies were not significantly different from
those of the indigenous population. CONCLUSION: Etoposide and cisplatin
combination chemotherapy has modest activity in patients with extensive
CUPS and, at the schedule and dosage given, it is associated with moderate
toxicity.

无环鸟苷亲脂性前体药物脂质体的制备及体外抗病毒活性(英文) 总被引:2,自引:0,他引:2
本文通过将无环鸟苷(acyclovir,简称ACV)2’位羟基分别与月桂酰氯或棕榈酰氯进行酯化反应,制得亲脂性前体药物无环鸟苷月桂酸酯和无环鸟苷棕榈酸酯(分别简称为C12-ACV和C16-ACV),使脂质体包封率从ACV的29.9%提高到C12-ACV的95.6%和C16-ACV的97.1%;漏泄实验表明在4℃透析60h后,一半以上的ACV从脂质体中漏泄,而C12-ACV和C16-ACV的滞留率分别为70%和80%;体外抗疱疹病毒的试验中,在最低试验浓度0.044μmol/L时,ACV不显示抗病毒活性,而C16-ACV脂质体抑制细胞病变率达75%,说明前体药物通过与脂质体脂膜的结合增加了药物的进入细胞能力,从而提高了ACV的抗病毒能力。 相似文献
