江苏省低碳经济评价指标体系的构建

江苏作为中国沿海最发达的省份之一,在经济快速增长的背后,其付出的环境代价也是巨大的。转变经济发展模式,发展低碳经济迫在眉睫。以江苏省经济资源环境资料为依据,选取评价低碳经济发展水平的各个指标,运用层次分析法进行权重赋值,形成了江苏低碳经济评价指标体系,并应用该体系对2012年的江苏经济状况进行验证,结果表明我省低碳经济发展水平目前还处在较低阶段。其对策包括改变能源消费结构,开发利用低碳能源;调整优化产业结构,发展低碳产业;转变消费观念,提倡低碳生活;建设城市公共交通体系,鼓励低碳出行;加强国际交流合作,研发低碳技术。     

长江三角洲地区经济增长的新引擎:技术创新

经济的持续增长依赖于以技术创新为核心的技术进步。实证研究表明：长三角地区经济增长的主要方式仍然是依靠大量的资本投入来拉动，技术创新尚未成为经济增长的新引擎。今后，长三角地区的技术创新必须以企业为主导，充分发挥国家创新引导系统、区域创新支持系统以及企业创新实施系统对长三角技术创新的引导和支持作用。     

Logistic曲线的一种简便计算配合法

1838年Verhulet首先提出以Logistic方程解释人口增长问题后,Pearl、Reed和Volterra等人先后以此方程描述和解释生物的生长、发育及人口出生、死亡等变动过程。近年来,Jensen对鱼类群体增长进行了Logistic方程的几种形式比较,Bharucha—Reid用此方程描述竞争与生克的群体增长;毛宗秀对我国人口增长数预测公式作了推演;在我们对心肌梗塞患者生存率的研     

经济发展与人口控制

衡量一个国家、一个地区的经济社会发展水平 ,不仅要看各项总量指标 ,更重要的是看人均指标。我国国民经济的许多总量指标已经居于世界前列 ,但按人口总数平均以后 ,就大大地落后了。这就提出了一个经济增长与人口控制问题。本文在论述了经济增长与人口控制的关系之后提出 ,发展经济是目的 ,控制人口是手段。应当把计划生育摆到与经济建设同等重要的位置 ,控制人口增长 ,提高人口素质     

略论人口、经济发展和计划生育的关系

人口规模、增长率及分布的变动对社会经济发展前景有着深远的影响，特别是人口膨胀给发展带来极大的负面影响，使可持续发展的社会面临着严峻的挑战。国际社会早在20世纪90年代初就十分关注人口和发展问题，联合国召开的一系列全球性会议都涉及人口与发展问题。例如，1994年9月在开罗召开的联合国“国际人口与发展会议”就明确指出，“将人口问题纳入经济和发展战略”，加速向可持续发展，减少贫困，减少人口增长，改进生活质量。其后“联合国新千年首脑会议（2000年9月）”和“联合国可持续发展首脑世界会议（2002年8月）”以及联合国人口基金反复强调在全球范围内控制人口增长，对促进经济发展的重要性。     

南通工业经济运行中投入与产出结构变动分析

南通工业经济运行中的投入与产出结构变动状况，可从要素投入、产出、投入与产出的关系等方面进行考察与分析。从投入与产出结构变动角度看，近年来南通工业经济运行存在5个方面的特征，即要素投入向优势行业集中，但工业装备质量有所下降；优势行业技术进步速度加快，但一般行业进展较为滞后；产值利税快速增长，但若干重要行业则发展较慢；结构协调效应日趋明显，但不同要素结构变动效益差异较大；工业经济整体运行质量稳步提升，但行业间不平衡现象较为突出。因此，当前在总体思路上应突出5大重点：特别重视工业装备质量的提高；切实加快一般行业的技术进步；大力促进高新技术产业发展；着力协调好扩大就业与提升技术水平的关系；促进工业经济整体运行质量与效益均衡提升。

长江经济带经济增长及其影响因素的实证分析

新中国建立以来尤其是改革开放以来,长江经济带经济快速发展,取得了巨大成就,但是区内各省市及其在各个时期经济增速存在明显差异。实证估计结果表明：物质资本投入对长江经济带经济增长的正向影响最大,其次是劳动投入;在非物质投入要素中,城市化进程对长江经济带经济增长的促进作用最大,其次是产业结构变动,再次是制度创新,人力资本投入的影响虽然也是正向的但不显著。为了促进长江经济带经济的进一步增长,必须在区内加强城市群建设;通过创新驱动产业结构转型升级;深化改革开放,推动制度创新;扩大国内消费以代替资本的过度投入。

产业结构高级化与经济增长 --对长三角地区的实证分析

改革开放尤其是20世纪90年代以来，长江三角洲及其15个城市地区产业结构高级化程度快速提升，提升的幅度和速度均高于全国平均水平。长三角15个城市地区之间产业结构高级化速度与改革开放初期结构高级化水平呈显著的负相关关系，结构高级化水平的差距大幅度缩小。长三角及其15个城市地区产业结构高级化水平的提高与其经济增长、经济水平存在显著的正向相关关系，产业结构高级化与经济增长密切关联且相互促进，但是由长三角15个城市地区构成的区域组合产业结构高级化上升速度与经济增长速度之间不存在相关关系。因此，虽然实际情况不同的地区应该选择不同的经济增长路径，但是当前及今后一个时期长三角及各城市地区均应继续推动产业结构高级化水平的提升，以发挥结构高级化与经济增长的显著正向互动作用，从而促进经济快速发展。     

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.

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.     

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.
