常用动物实验麻醉药物对大鼠心血管系统的影响

目的：探讨不同动物实验麻醉药物对大鼠心血管系统的影响。方法：采用BioPac MP150动态记录四种麻醉药物麻醉后大鼠的心电图、血压，采集麻醉后不同时间点大鼠的血糖以及实验终点肝肾功能、心肌酶、电解质。结果：水合氯醛可引起严重的室性心律失常，异氟烷对心率有抑制作用，戊巴比妥钠可引起大鼠心电图P波增高，乌拉坦可引起大鼠心电图J点抬高。乌拉坦、戊巴比妥钠均有升高动脉收缩压的作用。戊巴比妥钠、异氟烷有降低谷丙转氨酶、谷草转氨酶的作用，水合氯醛可引CK升高，异氟烷可降CK、CKMB，水合氯醛、戊巴比妥钠、异氟烷有降低肌酐的作用，四种麻醉药物均有降低尿酸、血钠、血钾的作用。结论：水合氯醛对心血管系统的影响明显，不适合用于心血管病的动物实验研究，戊巴比妥钠、乌拉坦、异氟烷可适当选择作为心血管病的动物实验研究。     

止消通脉宁对早期糖尿病大鼠肾脏肥大及高滤过的影响

肾脏肥大、高滤过是糖尿病肾病（DN）早期的病理生理基础，采用腹腔注射链脲佐菌素（STZ）复制糖尿病（DM）大鼠模型，研究止消通脉宁对DM大鼠肾脏肥大和高滤过的治疗作用，及一氧化氮（NO）和内皮素（ET）含量变化规律在DM早期肾脏肥大、高滤过率形成过程中的意义。结果提示DM早期肾脏NO产生增加可能是肾小球高滤过形成的重要因素，而止消通脉宁可以通过抑制NO合成而控制高滤过的形成。

乌拉坦对大鼠血糖的影响及其作用机理的研究

乌拉坦是生理学和药理学实验中常用的麻醉药,与其它麻醉药相比,乌拉坦对调控心血管机能的中枢神经系统抑制作用小,适于观察保留自律神经反射活动的麻醉动物实验.在糖尿病动物实验中,国外研究人员曾使用乌拉坦或巴比妥类药物麻醉动物,以减少采血这一恶性刺激本身对机体糖代谢的影响.已有报道,乌拉坦在家兔和大鼠诱发高血糖反应,其作用可被育亨宾、利血平、肾上腺摘除术所阻断,推测与儿茶酚胺释放增加有关.但是,也有实验证明,乌拉坦对禁食大鼠产生高血糖反应,而对非禁食大鼠无效.此外,尽管乌拉坦诱发猫产生高血糖反应,却不增加肾上腺素释放.目前,关于乌拉坦诱发动物高血糖反应的机理尚未完全阐明.因此,本实验观察了麻醉剂量乌拉坦对空腹大鼠、葡萄糖负荷大鼠、肾上腺素或四氧嘧啶诱发高血糖大鼠的血糖水平的影响,并探讨其对外源性胰岛素降血糖作用的影响.

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.     

Research of combined liver-kidney transplantation model in rats

Objective： To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods： SD rats served as both donors and recipients. 4℃ sodium lactate Ringer＇s was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava （IVC） inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results： Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion： This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.     

BLOOD PRESSURE CHANGE WITH AGE IN SALT-SENSITIVE TEENAGERS

Objective To observe blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P＜ 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P＜ 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.

Methods: Thirty cases of the treatment group were treated by acupuncture combined with spinal Tui Na, and thirty cases in the control group were treated by routine acupuncture. Results: The total effective rate was 93.3% in the treatment group, and 73.3% in the control group, with a significant difference between the two groups (P<0.05). Conclusions: Acupuncture combined with spinal Tui Na has good prospects for treatment of primary dysmenorrhea.
