近年来发现,许多非甲状腺疾病患者甲状腺功能可出现异常,血清T_3、T_4水平降低,且与病情的严重程度有一定相关性。本院自1991年～1992年对39例住院冠心病患者行血清T_3、T_4水平测定,现报告如下: 对象和方法     

非甲状腺疾病血清甲状腺激素异常的观察

用RIA法对174例8种常见内科非甲状腺疾病(NTI)患者行进了血清T_3、T_4、rT_3水平的观察。68例正常人作对照。结果显示,8神内科NTI患者均有血清T_3下降,部分伴T_4下降及rT_3升高,T_3/rT_3比值下降。属低T_3综合征占0.592;属低T_4综合征占12.1％。血清T_3、T_4、rT_3随病情变化而相应变化,并与预后相关。对NTI患者的甲状腺激素变化的机理作了简单讨论。     

临终前病人血T_3T_4的改变

近年来文献报道,一些非甲状腺疾病患者血清T_3和T_4水平降低。其降低程度与某些危重症的病情严重程度及死亡率有很高的相关性,即随着病情的恶化T_3T_4可进一步降低。本文对一组临终前患者进行血清T_3T_4测定并与正常人作比较。对象与方法本文收集1994年8月～1995年8月我院急诊科收治临终前患者28例,其中男性11例,女     

糖尿病对甲状腺功能的影响——低T_3综合征

本文探讨糖尿病列甲状腺功能的影响,测定了30例未控制糖尿病患者血清T_3、T_4、FT_3、FT_4和TSH浓度。尽管临床上无甲状腺功能异常的表现,但血清低T_3者有15例(50%),低FT_3 10例(33.3%),低T_4 1例(3.3%)血清FT_4和TSH浓度除个别病例轻度增高外均正常。血清T_3/T_4比值显著降低,FT_3%和FT_4%显著增高。低T_3的产生与患者伴有的酮症酸中毒、高渗综合征、肺部感染等急性并发症显著相关。血清T_3浓度与空腹血糖和糖基血红蛋白水平呈负相关(P<0.01)。胰岛素治疗后,低T_3、低FT_3、低T_4等各项甲状腺功能试验均恢复正常。因此,血清FT_4测定是与甲减相鉴别的可靠依据,T_3、FT_3、T_4测定可作为判断糖尿病病情、预后和疗效的辅助指标。     

血清T_3T_4值对呼吸系统疾病预后的初步观察(附64例分析)

本文对无甲状腺疾病的64例呼吸系统疾病患者,用放射免疫法测定了血清浓度T_3、T_4同时测定了动脉血气,电解质,血常规等。结果:20例呼衰中14例(70％)T_3值低下,下降的百分比明显高于其他疾病。动态观察了其中11例T_3值变化;2例随病情好转而上升或恢复正常,5例T_3值逐步下降的患者,有4例死亡,其中2例并伴有T_4值下降。显示T_6、T_4值的变化与患者的预后密切相关。     

糖尿病患者血清T_3T_4含量的RIA测定

<正> 非甲状腺疾病患者血清中T_3T_4水平低,从而引起甲状腺功能异常已有文献报道。为了解糖尿病患者甲状腺功能改变,我们采用放射免疫(RIA)对150例已确定为糖尿病的患者血清中T_3T_4进行了检测,现将结果报告如下:     

慢性呼吸衰竭和慢性支气管炎患者血清T3和T4测定结果分析

近年来发现,许多非甲状腺疾病可伴有血清三碘甲状腺原氨酸(T_3)和甲状腺素(T_4)浓度的降低,但临床上并无甲状腺功能减退的表现,分别称为“低T_3综合征”和“低T_4综合征”。国内陈氏等,于1981年报道了慢性支气管炎和肺心病T_4测定结果分析。由于肺心病患者常并发慢性呼吸衰竭,提示慢性呼吸衰竭患者的血清甲状腺素浓度亦可能呈现与肺心病患者     

老年肺心病患者血清中TH和TSH的变化

非甲状腺疾病患者可有血清中甲状腺激素(TH)异常,表现为低 T_3,T_4和正常促甲状腺激素(TSH),或低 T_3,高 T_4,也可表现为其他混合状态,但无甲状腺分泌减少的临床症状和体征,称为甲状腺病态综合征.郭庭杰等报道肺心病急性期与缓解期比较,T_3,T_4下降有显著性差异.我们观察了老年人肺心病患者缓解期和死亡病例的 TH 和 TSH 的变化.     

急性脑血管病患者甲状腺功能的变化及其临床意义

急性脑梗塞:肾病综合症、糖尿病、恶性肿瘤、肝硬化等常出现低T_3高rT_3血症,或称低T_3综合征。在非甲状腺疾病中甲状腺激素的变化主要是5’脱碘酶的活性改变而导致外围甲状腺激素脱碘代谢变化。为了解急性脑血管病初期垂体——甲状腺轴功能改变,我们测定了41例急性脑血管病患者进行了血清T_3、T_4、TSH、rT_3测定,并与正常健康组进行了比较观察,现报道如下。     

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.     

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.     

Dynamic Changes in Serum Estradiol and Progesterone levels in Patients of Premenstrual Syndrome with Adverse Flow of Liver-qi

Objective:To probe into the influence of changes of ovarian hormones on the pathogenesis of the specific sub-type premenstrual syndrome(PMS)and reveal partial microcosmic mechanisms of adverse flow of liver-qi.Methods:Estradiol(E2)and progesterone(P)levels in serum were determined at different phases of menstrual cycle by radioimmunoassay.Results:In the group of PMS with adverse flow of liver-qi.the secretive peak value Of E2 and P at the follicular phase significantly decreased,and the secretive peak value at the luteal phase did not come into being.Conclusions:Low E2 and P secretive peak at the follicular phase and absence of secretive peak at the luteal phase is one of the microcosmic mechanisms of PMS with adverse flow of liver-qi.One of the pathophysiologic mechanisms of specific sub-type PMS is probably the continuous low level of E2and P.     

Real-time Three-dimensional Echocardiography in Assessment of Left Ventricular and Right Ventricular Volumes

Real-time three-dimensional echocardiography (RT3DE)is a new ultrasound technique that enables dynamic threedimensional visualization and quantification of the heart in real time. Investigation of feasibility and methodology of RT3DE in determining left ventricular (LV) and right ventricular (RV) volumes, RT3DE was performed in 35 normal adults using Philips SONOS 7500 system with a 2-4 MHz matrix array transducer. The 60°×60° "pyramid" volume database was obtained and analyzed on a TomTec echo workstation. Both LV and RV volumes were calculated with four 3DE methods (i.e. apical 2, 4, 8, and 16-plane) through manually tracing ventricular endocardial borders in end diastole and end systole. Stroke volumes were then calculated. LV volume was also measured by 2DE Simpson's rule using GE VIVID 7 ultrasound machine.     

SCREENING FOR A 21-CHROMOSOME ABNORMALITY IN PREIMPLANTED EMBRYOS OF ELDERLY WOMEN

Increasing maternal age is the only etiological factor unequivocally linked to Down's syndrome in humans. The occurrence rate of newborns with Down's syndrome is about 1/220 in women over 35 years old. However, the occurrence rate in embryos fertilized in vitro, of the elder woman is unclear. Using FISH we screened the number of chromosome 21 in preimplanted embryos of 5 elderly women (average age, 38.4 years) to study the feasibility and necessity of screening trisomy 21 in embryos in patients over 35 years old at the in vitro fertilization (IVF) center.
