血清IGF-1、IGFBP-3水平和大肠癌关系的Meta分析

目的综合评价血清胰岛素样生长因子-1(IGF-1)、胰岛素样生长因子结合蛋白-3(IGFBP-3)水平和大肠癌的关系。方法利用Meta分析法对6篇关于血清IGF-1、IGFBP-3水平与大肠癌关系的研究文献进行定量综合分析。结果对于IGF-1，合并OR=1．56(95％CI：1．14～2．13)；按实验方法不同分层，间接酶联免疫吸附试验(ELISA)合并OR=1．92(95％CI：1．26～2．93)，IRMA法合并OR=1．23(95％CI：0．78～1．94)；对于IGFBP-3，合并OR=0．78(95％CJ：0．43～1．44)；按实验方法不同分层，ELISA法合并OR=0．46(95％CI：0．29～0．74)，免疫放射测定法(IRMA)合并OR=1．44(95％CI：0．93～2．23)。结论血清IGF-1高水平为大肠癌的独立危险因子，IGFBP-3与大肠癌的关联不具有统计学意义；IGFBP-3与大肠癌关系的各研究之间异质性是由实验方法不同而引起，但该结论尚需大样本并同时进行两种方法的测量证实。     

The potential role of insulin-like growth factor 1, insulin-like growth factor binding protein 3 and bone mineral density in patients with chronic hepatitis C virus in Cairo, Egypt

Insulin-like growth factor 1 (IGF-1) levels have been found to correlate with measurements of bone mineral density (BMD) in liver diseases. This study investigated the relationship between IGF-1, insulin-like growth factor binding protein 3 (IGFBP-3) and BMD in patients with chronic hepatitis C virus. This study was conducted for 30 patients with chronic hepatitis C virus infection (16 patients without and 14 patients with cirrhosis) and 11 healthy controls. Serum levels of IGF-1 and IGFBP-3 and BMD of the proximal femur and lumbar spine were measured in all subjects. Osteoporosis of the proximal femur and lumbar spine was found in 42.9% and 21.4%, respectively, of the patients with cirrhosis. Patients with liver cirrhosis and osteoporosis of the proximal femur and lumbar spine had lower IGF-1 (P < 0.001, P = 0.04, P = 0.04 respectively). BMD of the proximal femur was lower in cirrhotic patients compared with controls (P < 0.01). Patients with liver cirrhosis had lower IGFBP-3 than patients without cirrhosis and controls (P < 0.001). Patients with osteoporosis of the proximal femur had lower IGFBP-3 than those without osteoporosis (P < 0.01). IGF-1 and IGFBP-3 levels were lower in patients with liver cirrhosis. IGF-1 and IGFBP-3 may play a role in hepatic osteoporosis.

禁食和再喂养期间大鼠小肠胰岛素和胰岛素样生长因子-1受体的比较

胰岛素样生长因子-1（IGF-1）和胰岛素可能是肠道生长的重要调节因子。为了研究肠细胞萎缩和再生期间小肠IGF－1受体（IGF-IR）和胰岛素受体（IR），我们比较了禁食72小时和肠内再喂养24～72小时大鼠空肠IGF-IR和IR表达的指标。禁食引起肠萎缩，血浆胰岛素和IGF－1浓度降低以及空肠IGF-1信使RNA（mRNA）水平的明显降低，再喂养可逆转这些改变。禁食明显增加胰岛素与空肠特异性地结合，IR含量（达对照组的230％）和9．6kb和7．4kbIRmRNA转录本水平（分别达对照组的202％和218％）。再喂养时，这些IR指标迅速降到对照组水平。禁食时IGP-IR（用Scatchard分析）和IGF－1－RmRNA无明显的改变。再喂养后的前24小时间11-kbIGF－IRmRNA转录本明显增加（达对照组水平166％），IGF-IR数量增加3倍。我们的结论是：大鼠空肠的IR和IGF－IR受到不同营养物利用状态的调节。再喂养时空肠IGF－1和IGF－IR表达的向上调节表明，IGF作用途径在对肠内营养物产生肠道营养反应的过程中起作用。     

Correlation between the components of the insulin-like growth factor I system, nutritional status and visceral leishmaniasis

The role of the insulin-like growth factor I (IGF-I) system and nutritional status was studied in 241 children from a Brazilian area endemic for visceral leishmaniasis (VL). Thirty-nine children had the active form, 20 were oligosymptomatic, 38 were asymptomatic and 144 were not infected. Serum concentrations of growth hormone (GH), total and free IGF-I and IGF binding-protein 3 (IGFBP3) were measured by radioimmunoassay. Nutritional status was evaluated by anthropometric indicators and biochemical measurements. Total and free IGF-I and IGFBP3 were significantly reduced in the active form. Z scores for total and free IGF-I and for IGFBP3 were found to be significantly lower for active VL and oligosymptomatic individuals than for asymptomatic individuals, but never reached values 相似文献

The effect of long-term somatostatin analogue treatment on free and total insulin-like growth factor (IGF) -I, -II and IGF binding protein -1, -2 and -3 serum levels in euthyroid patients with active thyroid eye disease

The aim of this study was to investigate the effect of long-term somatostatin analogue (SM-a) treatment on serum levels of free (F) and total (T) insulin-like growth factor (IGF)-I, -II and IGF binding protein (IGFBP) - 1, -2 and -3 in euthyroid patients with active thyroid ophthalmopathy. For this purpose, we measured the above-mentioned parameters in 21 patients (11M, 10F), aged 50.8+/-11.8 years (range 35-70) and 19 healthy individuals matched for age, gender and body mass index (BMI). A total of 4 SM-a (sandostatin LAR((R))-30) injections, each monthly, were administered in each patient and measurements were performed prior to treatment and 20-30 days after the last injection, while in control individuals the same determinations were performed only once. All patients had active thyroid eye disease (TED), with clinical activity scores (CAS) >/= 4 (5.3+/-1.1) and positive orbital octreoscan in both eyes. Serum F and T IGF-I and IGF-II were determined using non-competitive, time-resolved monoclonal immunofluorometric assays. IGFBP-1 and IGFBP-2 were determined by an in-house radioimmunoassay, while IGFBP-3 by commercially available IRMA. Our results showed that F and T IGF-I, -II and IGFBP-1, -2 and -3 levels in patients before and after administration of SM-a were comparable and the levels did not differ significantly from those of controls. Furthermore, no statistically significant differences emerged in the ratio between molar weights of TIGF-I/IGFBP-3 and TIGF-II/IGFBP-3, as well as in the ratio of F/TIGF-I and F/TIGF-II in patients before and after SM-a therapy. Fourteen patients (66%) experienced a decline in CAS of at least >1 point in each eye after SM-a administration, whereas in the remaining the CAS did not change. Finally, no relationship was found between the levels of the above-mentioned parameters (post therapy) and CAS, octreoscan scores and thyroid hormones levels. In conclusion, we showed that although SM-a administration in euthyroid patients with active TED had a beneficial effect in a significant percentage of patients, this effect was not associated with a decline in the circulating IGF-I, -II and IGFBP-1, -2 and -3 levels, at least under the conditions of the present study. It can be postulated that if the mechanism of action of SM-a is through reduction of IGF-I levels, this effect is possibly exerted in the retrobulbar tissues by local paracrine/autocrine action.     

大豆异黄酮和补充钙对去卵巢大鼠骨密度及肝IGF-1mRNA表达的影响

目的 利用卵巢切除大鼠模型,研究大豆异黄酮和钙对卵巢切除大鼠骨密度及肝脏IGF-1基因表达的影响.方法 将6月龄雌性SD大鼠,按体重随机分成5组假手术组(Sham)、卵巢切除阴性对照组(OVX)、单纯大豆异黄酮组(SI)、单纯碳酸钙组(Ca)、大豆异黄酮加碳酸钙组(SI+Ca).所有大鼠饲以钙含量为3.732g/kg的低钙饮食喂养12周.实验结束时,利用双能X线骨密度扫描仪测量右侧股骨骨密度(BMD),采用逆转录-聚合酶链反应(RT-PCR)方法测定肝脏胰岛素样生长因子-1(IGF-1)基因表达水平.结果 SI+Ca组股骨远心端BMD为(0.263±0.007)g/cm2,Sham组为(0.267±0.008)g/cm2,两组间差异无统计学意义,但这两组BMD均显著性高于OVX(0.245±0.005)g/cm2、SI(0.258±0.011)g/cm2和Ca(0.255±0.004)g/cm2组(P＜0.05).肝脏IGF-1mRNA表达水平在Sham(0.200±0.023)g/cm2、SI(0.278±0.019)g/cm2、Ca(0.302±0.026)g/cm2及SI+Ca(0.231±0.025)g/cm2组中均显著性低于OVX(0.362±0.031)g/cm2,P＜0.05,SI+Ca组IGF-1mRNA表达水平(0.231±0.025)g/cm2低于SI(0.278±0.019)g/cm2和Ca(0.302±0.026)g/cm2两组,并差异有统计学意义.结论 SI+Ca能比单纯喂饲SI或Ca更好地防止卵巢切除大鼠股骨BMD的减小.37.95 mg/kg剂量的SI能够显著抑制由于卵巢切除引起的肝脏IGF-1 mRNA表达水平的上升.     

胰岛素样生长因子-1在急性脊髓损伤后对胶质细胞源性神经营养因子表达的影响

目的：观察急性脊髓损伤后胰岛素生长因子-1（IGF-1）对胶质细胞源性神经营养因子（GDNF）表达的影响。方法：Wistar成年大鼠以改良Allen打击装置制成脊髓损伤（SCI）模型。将大鼠随机分成2组：对照组，实验组（在脊髓损伤节段注入IGF=1），2组分别在4个时相点（脊髓损伤后6、12、24、48h）采用半定量逆转录-聚合酶链式反应（RT-PCR）技术观察GDNFmRNA在损伤脊髓中的表达情况。同时应用Tarlov评分法测定各组大鼠后肢的运动功能。结果：脊髓损伤后的4个时相点，实验组GDNF的表达较对照组明显增强，组间差异均具有统计学意义（P〈0．05）。实验组大鼠的后肢运动功能评分较对照组高，组间差异也具有统计学意义（P〈0．05）。结论：IGF-1可以促进脊髓损伤后大鼠肢体运动功能的恢复和损伤脊髓的修复。并且上调损伤脊髓段GD-NF的表达，其可能是IGF-1促进脊髓损伤修复的机制之一。     

Levels of plasma insulin-like growth factor I (IGF I), IGF II,IGF binding proteins,type 1 IGF receptor and growth hormone binding protein in community-dwelling elderly subjects with no malnutrition and no inflammation

Plasma samples from community-dwelling subjects aged 65 to 92 presenting no malnutrition and no inflammation (as assessed by albumin, transthyretin, CRP, and orosomucoid levels and BMI) were compared to those of healthy controls aged 20 to 65 to determine the effect of aging on the IGF system. Concentrations of IGF I, IGF II and IGFBP3 significantly decreased, and those of GHBP slightly increased with age from 20 to 92 years (n=327 r=-0.64 p<0.0001; n=45 r=-0.44 p<0.003; n=91 r=-0.23 p<0.03 and n=61 r=0.26; p<0.05 respectively). Western immunoblotting showed that the proteolysis of IGFBP3 was not significantly different in elderly and younger subjects. The affinity of the IGF type 1 receptor for IGF I was moderately lower (Ki=0.56 0.2 vs 0.33 0.1, nM respectively; p<0.005) and the number of binding sites was moderately higher (10.4 1.5 vs 8.1 1.9 binding sites/cell, respectively; p<0.03) in the elderly than in the younger adults. Our results suggest that the age-related decline in plasma levels of IGF I, IGF II and IGFBP3 occurs independently from malnutrition and inflammation processes. GHBP plasma levels, which reflect the number of GH receptors at the level of the liver, do not decline in our malnutrition-free elderly population, and thus are not involved in the decline of IGF I plasma levels with age. In the elderly, affinity and number of type 1 IGF receptor were close to those of younger subjects; the decline in IGF I plasma levels may account for the small rise in the number of type 1 IGF receptors binding sites per cell.
