慢性乙型肝炎病人NK细胞细胞毒活性的研究

本文应用3H-TdR释放法检测22例慢性乙型肝炎病人外周血NK细胞细胞毒活性。并以24名正常人作对照。结果:慢活肝12例及慢迁肝10例的NK细胞毒活性(x±s),分别为48.1±20.9％及32.6±9.8％,和对照组23.1±19.5％比较,P值分别<0.002和<0.05。而慢活肝亦较慢迁肝组增高(P值<0.05)。上述结果提示,慢活肝和慢迁肝病人NK细胞活性均较正常人增高。而肝脏病变较重的慢活肝较病变较轻的慢迁肝增高。NK细胞活性和肝细胞损伤及损伤程度一致。NK细胞可能参与慢乙肝肝细胞的损伤机制。     

膀胱癌患者术后的NK和ADCC细胞毒活性及其对HulFN-γ体外调节的反应性

观察了31例膀胱癌患者术后的外周血NK和ADCC细胞毒活性及其对人γ干扰素(HuIEN-γ)体外调节的反应性。结果表明,这些患者平均NK活性为32.48±15。5％,与正常人比较无显著差异(P>0。05);ADCC活性平均为43±21。44％,明显低于正常人(P<0.01)。进一步用HuIFN-γ体外调节这些患者细胞毒活性,可见调节后其NK活性增高至平均53。86±21.2％,比调节前明显增强(P<0.01);ADCC活性平均增高至50.99±23.66％,与调节前比较无显著性差异(P>0.05)。24例低NK活性患者中15例的NK活性经HuIFN-γ调节后恢复至正常水平以上,占62.5％;而25例低ADCC活性患者中仅4例经调节后恢复正常,占16％。提示HUIFN-γ对NK的促进作用似强于K细胞。本研究为临床应用干扰素治疗膀胱癌患者提供了某些有参考意义的实验依据。     

淋巴瘤病人外周血NK活性变化及其临床意义

应用~(126)I-UdR释放法,检测58例淋巴瘤病人及52例正常人外周血自然杀伤细胞(NK)活性。治疗前和复发病人NK活性分别为39.56±13.45％和43.31±13.30％,均明显低于正常人(58.01±8.21％)。Ⅲ～Ⅳ期病人NK活性(34.72±12.6％)明显低于Ⅰ～Ⅱ期病人(45.47±11.63％);伴有全身症状的病人(31.38±11.43％)明显低于无全身症状病人(45.91±11.45％)。NK活性与治疗效果有关。治疗后完全缓解者NK活性恢复正常,部分或未缓解者则无明显改善。NK活性与淋巴瘤组织类型无关。     

~(51)C_r-释放法检测肿瘤病人外周血细胞及外周血LAK细胞的NK活性

本文以国产~(51)Cr-铬酸钠为标记物,应用~(51)Cr-释放法进行了肿瘤病人的 NK 细胞活性检测。评价了国产~(51)Cr-铬酸钠用于~(51)Cr-释放法检测细胞毒活性的可行性(NR=21.3±4.6);检测晚期癌症病人外周血淋巴细胞(PBL)NK 活性7例(SR=8.1±3.3).良性肿瘤病人 PBL NK 活性15例(SR=22.9±9.8);并研究了天然人白细胞介素-2(hlL-2)激活肿瘤病人 PBL 诱生 LAK 细胞 NK 活性的变化规律,一次性激活(1000U/ml)NK 活性高峰出现在24～48小时。     

胃病患者自然杀伤细胞活性的研究

应用~(125)IUdR 释放试验,同时测定胃癌与良性胃病患者外周血自然杀伤细胞活性,发现胃癌病人的NK活性显著低于正常人,慢性萎缩性胃炎病人NK活性虽然高于胃癌病人,但却显著低于正常人。本文还进一步研究了正常人、胃癌切除术后病人及进展期胃癌病人血浆对NK细胞功能的影响。发现进展期胃癌病人血浆对正常人NK活性有明显的抑制作用,提示胃癌病人血浆具有抑制NK细胞活性的物质。     

慢性肝病患者自然杀伤细胞活性观察

应用~(125)I—UdR释放法对25例正常人及50例慢性肝病患者外周血NK活性进行了观察.发现男性NK活性(平均为59.8±10.5%)显著高于女性者(平均为41.0±6.5%)P<0.05.慢性肝病患者NK活性(平均为31.8±18.8%)显著低于正常对照者(平均为57.4±11.0%)P<0.001.且肝硬化病人NK活性(平均为31.6±16.5%)显著低于慢性肝炎者(平均为35.8±18.5%)P<0.05。推测慢性肝病患者NK活性降低可能与乙肝病毒感染有关系。     

胃癌病人自然杀伤细胞活性检测及变化因素分析

以Na_2~(51)CrO_4标记K562靶细胞,应用放射性同位素释放法,对正常人和胃癌病人外周血NK细胞活性进行了检测,发现胃癌病人NK活性的高低与肿瘤组织分化程度的高低相平行,即高分化胃癌病人NK细胞活性无显明改变,低分化与不良分化胃癌病人NK细胞活性明显降低;而无论是限局型还是浸润型病人,NK细胞活性均明显降低。干扰素浓度为500IU/ml时,可提高正常人(40.5%)和病人(36.6%)的NK细胞活性,其中限局型病人对干扰素的反应能力优于浸润型病人。     

消化性溃疡及胃癌患者外周血IL-2活性水平及其与NK活性的关系

本文观察了40例健康人,28例胃癌,26例球部溃疡,19例胃溃疡及9例胃溃疡伴不典型增生病人的IL—2活性及NK细胞活性。其中胃癌病人IL—2及NK活性最低,与健康对照组比较,P<0.0005;胃溃疡伴不典型增生病人的IL—2活性及NK活性,虽然高于胃癌病人,但却显著低于健康人,统计学有意义。将正常人和病人的PBMC分别用IL—2处理后,观察IL—2对NK细胞的调节作用,IL—2对正常人及病人的NK细胞活性均有促进作用,但未能使NK活性显著低下的胃癌病人的NK活性恢复至正常人水平。     

癌性腹水抑制自然杀伤细胞活性及消炎药物逆转作用的研究

本文报道转移性肝癌12例,淋巴瘤8例,卵巢癌10例患者的腹水在体外培养系统中对正常人自然杀伤细胞(NK)活性的抑制性影响。三种癌性腹水(1:10稀释)可使正常人周血淋巴细胞 NK 活性由55.77±4.3%分别下降到23.7±2.7%,34.5±3.3%,38.1±3.4%(P<0.01～0.05)。而且抑制性影响可因腹水浓度降低而减弱。三种癌性腹水对同一正常人的 NK 活性抑制程度有明显的差别。当腹水中加有消炎痛(4μg/m1)或炎痛喜康(6μg/ml)可使正常人的 NK 活性分别回升到46.1±1.5%,48.0±2.4%,50.0±2.4%;29.9±3.0%,40.0±2.5%,47.0±2.4%。消炎痛(4μg/ml)可以大部分抵消卵巢癌、淋巴瘤腹水对正常 NK 的抑制,而炎痛喜康的逆转作用较消炎痛差。癌性腹水中淋巴细胞 NK 活性低,但培养系统中有消炎痛或炎痛喜康时,可使 NK 活性明显提高。     

红斑狼疮患者NK细胞的变化

本文报道了126例红斑狼疮(SLE)患者及19例其它胶原疾病患者的NK活性,用LDH释放测定法发现SLE患者NK活性为12.01±8.03%,对照组为32.45±8.17%(P<0.001)。9例类风关的NK活性也低(P<0.001),绝大多数SLE患者的NK活性比正常人的NK活性均值低,仅2例轻型患者(1.59%)的NK活性超过正常人均值。16例具有肾脏损害的SLE患者NK活性更低(7.11±5.11%),20例未用激素治疗的NK活性同样受到损害(13.43±10.99%)。说明SLE患者的NK功能受损,也反映了NK活性与疾病的严重与否有关。     

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.

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.
