用扫描电镜铸型法观察大鼠肝内胆道系统以及与肝组织间的空间结构关系。结果:当用中等剂量的铸型剂(80μl)从总胆管逆向注入时,可见小叶间及小叶内胆管及Mall's间隙内有铸型剂充,胆小管中未见铸型剂;当用较大量(200μl)注入时,除上述部位充盈外,还可见肝锹氏间、直血窦内有铸型剂。表明:铸型剂通过胆管上皮间隙,进入胆管周围淋巴而入Mall's间隙;当铸型剂增多时,可经Mall's间隙进入锹氏间隙和  相似文献

逆行胆道造影,是手术后放入T形管(或直接穿入胆管)并注入造影剂以显示胆管的检查。目的是使胆总管、左右肝管及分支充盈显示,以帮助了解胆管内有无炎症、结石、蛔虫及狭窄等。肝分泌的胆汁,经过一套管道系统排至十二指肠,在肝外的部分称胆道系统。胆道系统包括左右肝管、肝总管、胆总管、胆囊等。胆囊俗称苦胆,象一个鸭梨,位于肝下面的胆囊窝内,可分为底、体、颈三部。胆囊底为钝圆形,突出在肝前缘,与腹前壁相贴,它的表面投影在右锁骨中线与右肋弓相交处,此处为胆囊触诊区。胆囊颈移行为胆囊管并与肝总管汇合成胆总管,胆总管…  相似文献

目的探讨肝脏双功能对比剂Gd-BOPTA应用于胆道成像的可行性及临床价值。方法应用GdBOPTA对15例患者(对照组10例,梗阻性黄疸组5例)进行胆道成像。比较胆系结构的显示(高信号对比剂充盈)率。测量计算肝脏和胆囊信号强度的变化值及其比值。结果对照组10例均能够显示胆总管、胆囊和肝总管,左右肝内胆管和胆囊管的显示率大于60%。梗阻性黄疸组1例于扩张胆总管内高信号胆汁对比下可见软组织信号充盈缺损。其余4例总胆红素大于131.4μmol/L,胆道未能显影。两组延迟扫描胆囊、肝脏信号强度变化及其比值差异有显著性(p=0.001,004,0.001),对照组均高于梗阻性黄疸组。结论Gd-BOPTA在非梗阻性黄疸患者中可以得到较为满意的胆道二维及三维图像,为评价肝脏功能以及诊断或排除胆道病变提供了新的安全、无创检查手段。  相似文献

目的 分析研究经皮肝胆道穿刺硬质胆道镜探查取石术(PTCSL)治疗胆总管结石梗阻的影响疗效的相关因素,以进一步提高手术疗效及安全性。方法 收集广州医科大学附属第一医院总院和海印分院于2013年1月至2019年3月约5000例行胆道结石手术病人的病案资料,从中筛出罹患胆总管结石并行经皮肝胆道穿刺胆道镜探察取石术(PTCSL)治疗的患者43例,其中男26人,女17人,年龄22~93岁;手术全部成功。每例取石 1~2 次。结果 经统计分析得出,穿刺胆管直径和穿刺胆管与胆总管夹角对PTCSL是否能一期手术取净结石有较大的影响,而进一步相关性分析可见穿刺胆管直径mm与ptcsl一期取净间有着负相关关系;穿刺胆管与胆总管夹角(冠状位)与ptcsl一期取净间有着正相关关系。结论 进行经皮肝胆道穿刺硬质胆道镜探查取石术时,穿刺胆管直径越大,一期取净效果越差,穿刺胆管与胆总管夹角越大对一期取净结石效果越好,  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

The 6th National General Congress of Chinese Association of Integrative Medicine (CALM) was convened at 19-20, April 2008 in Beijing. Academician CHEN Zhu, the minister of Ministry of Health indicated at the congress that the integration of Chinese and Western medicine is very well in keeping with the situation of our country and the general rule of development in medical science; and as a good integration of Chinese medicine and Western medicine, it is mutually beneficial and advantageous to both of them. Seeing the creativity shown in integrative medical investigation in theoretic and methodological sides, we should and must persist in and develop it.  相似文献
