不同剂量布托啡诺对TCI异丙酚全麻患者BIS及气管插管反应的影响

[[摘要] 目的 观察靶控输注（TCI）异丙酚诱导中，维持脑电双频指数（BIS）为55±5时，复合不同剂量的布托啡诺对异丙酚靶浓度及血流动力学的影响。 方法 择期全麻手术患者80例，ASA I或II级，年龄18~65岁，随机分为4组（n=20）:I、Ⅱ、Ⅲ、Ⅳ组为不同剂量布托啡诺。麻醉诱导：异丙酚起始靶浓度（Cp）为3.0 ug/mL，每30秒以0.3 ug/mL浓度递增，至患者意识消失，且BIS在55±5左右时给予布托啡诺30 ug/kg（I组），40 ug/kg（Ⅱ组），50 ug/kg（Ⅲ组），60 ug/kg（Ⅳ组），维持予先设定的BIS不变，根据BIS调整异丙酚靶浓度以0.3ug/ml浓度递增或递减。BIS稳定后再静脉注射维库溴铵0.12mg/kg，肌松满意后行气管插管。记录麻醉前3 min（T0），BIS为55±5左右时给阿片类药前即刻（T1），给阿片类药BIS稳定后 （T2），插管前即刻（T3），插管后即刻（T4），插管后3 mim（T5），6 mim（T6）各时间点CP、HR、MAP及BIS。结果 各组T0、T1时刻CP，HR，MAP，及BIS差异无统计学意义（P＞0.05）；与I组比较，Ⅱ、Ⅲ、IV组在T2至T6时刻CP明显减小（P<0.05）。I组在T4至T6时刻HR、MAP上升明显（P<0.05），而Ⅱ、Ⅲ、IV组无明显变化（P＞0.05）。 结论 TCI异丙酚诱导时，以BIS降至55±5为指标，静脉注射布托啡诺可进一步降低异丙酚的血浆及效应室靶浓度；可减轻异丙酚诱导时所导致HR减慢和MAP下降，静脉注射 40~60 ug/kg布托啡诺具有较好的镇静作用，可较好地抑制气管插管反应。

氯胺酮对七氟烷麻醉维持时Narcotrend监测的影响

[摘要] 目的 观察七氟烷麻醉维持时0.2、0.5、1.0 mg/kg的氯胺酮对Narcotrend的影响。方法 ASA Ⅰ~Ⅱ 级准备接受腹部手术的患者40例,随机分为Ⅰ～Ⅳ组对应0.2、0.5、1.0 mg/kg的氯胺酮及生理盐水。七氟烷进行麻醉诱导及维持,气管插管后待麻醉深度稳定10 min,没有外科刺激时,静脉注射氯胺酮或生理盐水,连续观察15 min血流动力学及Narcotrend 指数（NI）的变化并记录。结果 给药前各组的NI 基本无差异, Ⅰ组39.4±3.0 , Ⅱ组37.5±2.6,Ⅲ组38.0±4.5 , Ⅳ组38.4±4.5。给药后Ⅰ组与Ⅳ组的NI在各个时间点均无差异;Ⅱ组和Ⅲ组与Ⅳ组相比,NI 明显升高,但Ⅱ 组的Narcotrend 分级并无变化,而Ⅲ组NI明显升高并使Narcotrend 分级显著提高。结论 在七氟烷麻醉维持时,0.2 mg/kg的氯胺酮对NI无影响,0.5 mg/kg时NI增加,但不影响Narcotrend 分级,而1.0 mg/kg的氯胺酮明显增加NI, 并改变Narcotrend分级,可能导致麻醉深度的误判,致使麻醉药物过量。

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.

The comparative studies of the influences of Urapidil and Nicardipine on sino-atrial node function, atrio-ventricular node function and hemodynamics

Objective:To investigate the influences of urapidil and nicardipine on rabbit sinus function,atrio-ventricular node function and hemodynamics.Methods:Thirty-two Angora's rabbits were selected and randomly divided into four groups.U1 group:urapidil 0.25 mg/kg;U2 group:urapidil 0.5 mg/kg;N1 group:nicardipine 10 μg/kg;N2 group:nicardipine 20 μg/kg.All these medicine were administrated within 30 seconds.Measurements were taken before and after the administration of urapidil or nicardipine for the following data:mean blood pressure(MAP),heart rate(HR),sino-atrial conduction time(SACT),maximal sinoatrial recovery time(SNRTmax)corrected sinus node recovery time(CSNRT),index of sinus node recovery time(SNRTI),Wenckebach A-V conduction frequency (WB),and P-R interval.Results:Significant MAP and HR changes were identified in all of the four groups before and after administration of both urapidil and nicardipine.No significant changes could be found in the rest of the parameters.Intergroup analysis showed that SACT and CSNRT of N1 and N2 groups were shorter than those of the U2 group(P＜0.01);the MAP decreased(P＜0.01)and the HR increased drastically(P＜0.01).Conclusions:Neither urapidil(0.25 mg/kg,0.5 mg/kg)nor nicardipine(10μg/kg,20μg/kg)has any significant influence on rabbit sinus function or rabbit atrio-ventricular node function.Nicardipine could be a better choice than urapidil for parafunctional sinus node patients.     

Expression of OPGmRNA and ODFmRNA in the patients of hip fracture due to osteoporosis

Objective：To investigate the gene expression of osteoprotegerin（OPG） and osteoclast differentiation factor（ODF） in the bone tissue of patients with hip fracture due to osteoporosis. Methods：OPGmRNA and ODFmRNA in the bone tissue in 50 cases of osteoporosis sufferers（over 50 years old） with hip fracture（Observer Group） and 30 cases of hip facture sufferers with no osteoporosis（Control group） were analyzed with the Semi-Quantitative RT-PCR method. Results：The mRNA expressed of ODF, OPG were both high in the patients with hip fracture. In the control group, the expression of OPG mRNA was observed, while the expression of ODF mRNA was very slight. Conclusion：Aged patients contained all signals including OPG, ODF that are essential for inducing osteoclastogenesis and promoting bone resorption.     

The clinicopathological and immuohistochemical analysis of solid-pseudopapillary tumor of the pancreas： report of 9 cases

Objective：To investigate the clinical features, pathological characteristics and immunophenotype of solid-pseudopapillary tumor of the pancreas（SPTP）. Methods：Nine surgically treated cases of SPTP were retrospectively reviewed. Hematoxylin and Eosin（HE） staining and immunohistochemical staining were used to analyze all cases, and the general clinical data was collected. Results：Six patients were asymptomatic except for a palpable mass. Two patients complained of vague-epigastric pain. One patient appeared jaundice. The tumor was encapsulated and solid tissues alternately with cystic tissues. Histologically, the histological structure of solid portion was pseudopapillary with a fibrovascular core. Tumor cells were uniform and medium-sized which were arranged in sheets ets or nests or pseudopapillary patterns. Immunohistochemical studies demonstrated that SPTP proved positive in vimentin（9/9 cases）, AAT（9/9 cases）, NSE（9/9 cases）, ACT（7/9 cases）, CK20（2/9 cases）, CgA（1/9 cases）, S-100（3/gcases）, PR（4/gcases）, Syn（3/9 cases） and CD56（5/9cases）, negative in CEA and ER. Conclusion：SPTP is a tumor predominantly occurring in young women frequently without special symptoms. This tumor has various characteristical histological patterns with different immunophenotype.

Investigation of Matrix Metalloproteinase -1, 2 and tissue inhibitor of matrix metalloproteinases-1 in Endometriosis

Objective： To explore the role of matrix metalloproteinase-1,2 （MMP-1, MMP-2） and tissue inhibitor of matrix metalloproteinases-1 （TIMP-1） in endometriosis. Methods： The eutopic and ectopic endometria from 40 subjects suffering from endometriosis and regular.endometria from 40 subjects （excluding endometriosis） were collected and examined by in situ hybridization technology and western blot assay. Results： Both expressions of MMP-1 and -2 were stronger in ectopic endometrium and eutopic endometrium than in normal endometrium. On the contrary, the expression of TIMP-1 in ectopic endometrium and eutopic endometrium was lower. The differences were significant （P 〈 0.01 ）. Moreover, there was no relationship among the expressions of MMP-1, 2 and TIMP-1 in ectopic endometrium. Conclusion： The expressions of MMP-1, 2 and TIMP-1 lose balance and lack of periodic changes in ectopic endometrium , which explains the biological invasive behavior of endometriosis. It was suggested-that regulating the balance between the MMPs and TIMP-1 should be an ideal therapeutic target to endometriosis.
