| 1 | Quantitative analysis of vascular endothelial growth factor, microvascular density and their clinicopathologic features in human hepatocellular carcinoma显示文摘BACKGROUND: Angiogenesis is known to be essential to the survival, growth, invasion, and metastasis of tumor cells. Vascular endothelial growth factor (VEGF) are an important angiogenic factor regulating tumor angiogenesis, but its significance and tumor pathologic features are un- clear in hepatocellular carcinoma (HCC). In the present study, we analyzed expression of tissue VEGF, alteration of microvascular density (MVD) in microvessel angiogenesis, development and metastasis of HCC, and level of serum VEGF in differential diagnosis of benign and malignant liv- er diseases. METHODS: Tumor specimens were prospectively collected from HCC patients undergoing resection. Total RNAs were extracted and the expression levels were detected from different parts of HCC tissues. The cellular distributions of VEGF and MVD of liver tumors and their paracancerous and distal cancerous tissues were investigated by streptavi- din peroxidase (S-P) immunohistochemistry, respectively. The VEGF levels of circulating blood and hepatoma tissues were measured by enzyme-linked immunosorbent assay. RESULTS: The incidence of VEGF expression was 63.9% in HCCs (23/36 cases), 78.3% in non-encapsulated HCCs (18/23), and 90.9% in HCCs with extrahepatic metastasis (10/11), respectively. The VEGF expression was tightly correlated with MVD (P <0.01). The MVD in HCC with metastasis, low differentiation or non-encapsulation was significantly higher than that in HCC with intact capsule, high differentiation, or no metastasis. No significant diffe- rence was found between VEGF, MVD, tumor size, and hepatitis virus infection. The level of total RNA in HCC tis- sues was significantly lower but the VEGF level significantly higher than those in paracancerous or distal cancerous ones (P<0.01). The abnormal expression levels of VEGF in sera of HCC patients were directly correlated with the me- tastasis and recurrence of tumors. CONCLUSION: The high expression of VEGF and abnor- mality of tissue MVD are useful predictors for vascular inva- sion and metastasis of liver tumors. | Deng-Fu Yao, Xin-Hua Wu, Yong Zhu, Gong-Sheng Shi, Zhi-Zhen Dong, Deng-Bing Yao, Wei Wu, Li-Wei Qiu and Xian-Yong Meng Nantong, China Research Center of Clinical Molecular Biology , Department of Pathology and Department of Gastroenterology , Affiliated Hos- pital of Nantong University Department of Diagnostics , and Institute of Neurosciences , Nantong University Nantong 226001, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，2： | 81 |

| 4 | Inhibitory effect of IGF-Ⅱ antisense RNA on malignant phenotype of hepatocellular carcinoma显示文摘INIRODUCTIONAccording to the therapeutic effect and strategy ofantisense RNA for hepatoccllular carcinoma(HCC),we have specifically synthesized partialcDNA of human insulin-like growth factor Ⅱ(IGF-Ⅱ)and constructed IGF-Ⅱ cDNA antisenseeukaryotic expression vector.The constructedvector was introduced into hepatoma cell lineSMMC-7721 to block the intrinsic IGF-Ⅱexpression.The biological behavior changes ofhepatoma cells were observed.All these | Dong Hua Yang Ming Qing Zhang Jiang Du Chong Xu Oiao Ming Liang Ji Fang Mao Han Rong Qin Zi Rong Fan Department of Gastroenterology,Zhujiang Hospital,the First Military Medical University,Guangzhou 510282,China Laboratory of Molecular Biology,Zhujiang Hospital,the First Military Medical University,Guangzhou,China Departrnent of Biochemistry,the Second Military Medical University,Shanghai,China | 2000 | World Journal of Gastroenterology2000，6，2： | 54 |
| 5 | 一种基于FP-Growth的频繁项目集并行挖掘算法显示文摘FP-Growth算法是基于FP树挖掘频繁项目集的经典算法,为提高FP-Growth算法挖掘大规模数据频繁项目集的效率,提出了一种基于FP-Growth的频繁项目集并行挖掘算法FPPM。该算法基于Map/Reduce并行模型,在每个计算节点上首先构造局部频繁模式树,并对之进行挖掘得到局部频繁项目集,然后合并局部频繁项目集以得到全局频繁项集,由于此时得到的结果并不完备,所以对合并后未达到最小支持度阈值的项目集,重新计算其支持数。介绍了FPPM算法的设计思想,测试了其性能。实验结果表明FPPM算法具有较好的可扩展性。 | 章志刚 吉根林 | 2014 | 计算机工程与应用2014，50，2： | 43 |
| 6 | Expression of vascular endothelial growth factor and its role in oncogenesis of human gastric carcinoma显示文摘AIM To establish the role of vascular endothelial growth factor (VEGF) in the oncogenesisof human gastric carcinoma more directly.METHODS The expression of VEGF and its receptor kinase-domain insert containing receptor (KDR) in human gastric cancer tissue were observed by immunohistochemical staining. VEGF levels were manipulated in human gastric cancer cell using eukaryotic expression constructs designed to express the complete VEGF165 complimentary DNA in either the sense or antisense orientation. The biological changes of the cells were observed in which VEGF was up-regulated or downregulated.RESULTS VEGF-positive rate was 50%, and VEGF was mainly localized in the cytoplasm and membrane of the tumor cells, while KDR was mainly located in the membrane of vascular endothelial cells in gastric cancer tissues and peri-cancerous tissue. In 2 cases of 50 specimens, the gastric cancer cells expressed KDR,localized in both the cytoplasm and membrane.Introduction of VEGF165 antisense into human gastric cancer cells ( SGC-7901, immunofluorescence intensity,31.6%)) resulted in a significant reduction in VEGFspecific messenger RNA and total and cell surface VEGF protein ( immunofluorescence intensity, 8.9%)(P<0.05). Conversely, stable integration of VEGF165 in the sense orientation resulted in an increase in cellular and cell surface VEGF (immunofluorescence intensity,75.4%) (P<0.05). Lowered VEGF levels were associated with a marked decrease in the growth of nude mouse xenografted tumor (at 33 days postimplantation, tomor volume: 345.40 ± 136.31 mm3) (P<0.05 vs control SGC7901 group: 1534.40 ± 362.88 mm3), whereas up-regulation of VEGF resulted in increased xenografted tumor size (at 33 days postimplantation, tomor volume: 2350.50 ± 637.70mm3) (P<0.05 vs control SGC-7901 group).CONCLUSION This study provides direct evidence that VEGF plays an important role in the oncogenesis of human gastric cancer. | Du-Hu Liu Xue-Yong Zhang Dai-Ming Fan Yu-Xin Huang Jin-Shan Zhang Wei-Quan Huang Yuan-Qiang Zhang Qing-Sheng Huang Wen-Yu Ma Yu-Bo Chai Ming Jin Institute of Digestive Disease,Xijing Hospital,~2 Department of Gastroenterology,Tangdu Hospital,~3Department of Histology and Embryology,~4 Department of Microbiology,~5 Department of Biochemistry,Fourth Military Medical University,Xi’an 710033,Shaanxi Province,China | 2001 | World Journal of Gastroenterology2001，7，4： | 37 |

| 8 | Recent advances in fermented feeds towards improved broiler chicken performance, gastrointestinal tract microecology and immune responses: A review显示文摘Previously, fermentation has been associated with methods that improve the nutritional value of unconventional feed ingredients for broilers. In recent decades, the fermentation process has been employed to produce functional feeds that have the potential to improve broiler gastrointestinal tract microecology, health and production performance. Some of the functional ingredients found in fermented feed include lactic acid bacteria(LAB), lactic acid and other organic acids, and appear to play major roles in determining the beneficial effects of fermented feed on broiler gut health and performance. Unlike the pig, the available literature on broiler fermented feed is still rather limited. This review describes recent advances in the use of fermented feed(on the basis of conventional and unconventional feed ingredients) in broilers. Similarly, this review also shows that additional research is necessary to exploit fermented feed as a viable food source in broiler nutrition. | Sugiharto Sugiharto Samir Ranjitkar | 2019 | Animal Nutrition2019，，1： | 37 |

| 11 | Reduction of tumorigenicity of SMMC-7721 hepatoma cells by vascular endothelial growth factor antisense gene therapy显示文摘AIM To test the hypothesis to block VEGFexpression of SMMC-7721 hepatoma cells mayinhibit tumor growth using the rat hepatomamodel.METHODS Amplifiy the 200 VEGF cDNAfragment and insert it into human U6 genecassette in the reverse orientation transcribingsmall antisense RNA which could specificallyinteract with VEGF165, and VEGF121 mRNA.Construct the retroviral vector containing thisantisense VEGF U6 cassette and package thereplication-deficient recombinant retrovirus.SMMC-7721 cells were transduced with thesevirus and positive clones were selected withG418. PCR and Southern blot analysis wereperformed to determine if U6 cassette integratedinto the genomic DNA of positive clone.Transfected tumor cells were evaluated for RNAexpression by ribonuclease protection assays.The VEGF protein in the supernatant of parentaltumor cells and genetically modified tumor cellswas determined with ELISA. In vitro and in vivogrowth properties of antisense VEGF cell clonein nude mice were analyzed.RESULTS Restriction enzyme digestion andPCR sequencing verified that the antisense VEGFRNA retroviral vector was successfullyconstructed. After G418 selection, resistantSMMC-7721 cell clone was picked up. PCR andSouthern blot analysis suggested that U6cassette was integrated into the cell genomicDNA. Stable SMMC-7721 cell clone transducedwith U6 antisense RNA cassette could express200bp small antisense VEGF RNA and secretereduced levels of VEGF in culture condition.Production of VEGF by antisense transgeneexpressing cells was 65 ± 10 ng / L per 106 cells,420 ± 45 ng/L per 106 cells in sense group and 485± 30 ng/L per 106 cells in the negative control group, (P<0.05). The antisense-VEGF cell clone appeared phenotypically indistinguishable from SMMC-7721 cells and SMMC-7721 cells transfected sense VEGF. The growth rate of the antisense-VEGF cell clone was the same as the control cells. When S. C. was implanted into nude mice, growth of antisense-VEGF cell lines was greatly inhibited compared with control cells.CONCLUSION Expression of antisense VEGFRNA in SMMC-7721 cells could decrease thetumorigenicity, and antisense-VEGF genetherapy may be an adjuvant treatment forhepatoma. | Yu Cheng Tang Yu Li Guan Xiang Qian Department of Biochemistry, Shanghai Second Medical University, Shanghai 200025, China | 2001 | World Journal of Gastroenterology2001，7，1： | 33 |
| 12 | Delayed hepatocarcinogenesis through antiangiogenic intervention in the nuclear factor-kappa B activation pathway in rats显示文摘BACKGROUND:The active form of nuclear factor-kappa B(NF- κB)is involved in the initiation,generation,and development of hepatocellular carcinoma(HCC),and is up-regulated in inflammation-associated malignancies.We investigated the dynamic expression of NF-κB and its influences on the occurrence of HCC through antiangiogenic(thalidomide) intervention in NF-κB activation. METHODS:Hepatoma models were induced with 2-fluorenyl- acetamide(2-FAA,0.05%)in male Sprague-Dawley rats,and thalidomide(100 mg/kg body weight)was administered intragastrically to intervene in NF-κB activation.The pathological changes in the liver of sacrificed rats were assessed after hematoxylin and eosin staining.NF-κB mRNA was amplified by RT-nested PCR.The alterations of NF-κB and vascular endothelial growth factor(VEGF)expression were analyzed by enzyme-linked immunosorbent assay,immunohistochemistry,and Western blotting. RESULTS:Rat hepatocytes showed denatured,precancerous,and cancerous stages in hepatocarcinogenesis,with an increasing tendency of hepatic NF-κB,NF-κB mRNA,and VEGF expression,and their values in the HCC group were higher than those in controls(P<0.001).In the thalidomide- treated group,the morphologic changes generated only punctiform denaturation and necrosis at the early or middle stages,and nodular hyperplasia or a little atypical hyperplasia at the final stages,with the expression of NF-κB (χ2=9.93,P<0.001)and VEGF(χ2=8.024,P<0.001)lower than that in the 2-FAA group. CONCLUSION:NF-κB is overexpressed in hepatocarcinogenesis and antiangiogenic treatment down-regulates the expression of NF-κB and VEGF,and delays the occurrence of HCC. | Dong, Zhi-Zhen Yao, Deng-Fu Wu, Wei Yao, Min Yu, Hong-Bo Shen, Jun-Jun Qiu, Li-Wei Yao, Ning-Hua Sai, Wen-Li Yang, Jun-Ling | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，2： | 31 |
| 13 | Beneficial effects of naringenin in liver diseases: Molecular mechanisms显示文摘Liver diseases are caused by different etiological agents, mainly alcohol consumption, viruses, drug intoxication or malnutrition. Frequently, liver diseases are initiated by oxidative stress and inflammation that lead to the excessive production of extracellular matrix(ECM), followed by a progression to fibrosis, cirrhosis and hepatocellular carcinoma(HCC). It has been reported that some natural products display hepatoprotective properties. Naringenin is a flavonoid with antioxidant, antifibrogenic, anti-inflammatory and anticancer properties that is capable of preventing liver damage caused by different agents. The main protective effects of naringenin in liver diseases are the inhibition of oxidative stress, transforming growth factor(TGF-β) pathway and the prevention of the transdifferentiation of hepatic stellate cells(HSC), leading to decreased collagen synthesis. Other effects include the inhibition of the mitogen activated protein kinase(MAPK), toll-like receptor(TLR) and TGF-β non-canonical pathways, the inhibition of which further results in a strong reduction in ECM synthesis and deposition. In addition, naringenin has shown beneficial effects on nonalcoholic fatty liver disease(NAFLD) through the regulation of lipid metabolism, modulating the synthesis and oxidation of lipids and cholesterol. Moreover, naringenin protects from HCC, since it inhibits growth factors such as TGF-β and vascular endothelial growth factor(VEGF), inducing apoptosis and regulating MAPK pathways. Naringenin is safe and acts by targeting multiple proteins. However, it possesses low bioavailability and high intestinal metabolism. In this regard, formulations, such as nanoparticles or liposomes, have been developed to improve naringenin bioavailability. We conclude that naringenin should be considered in the future as an important candidate in the treatment of different liver diseases. | Erika Hernández-Aquino Pablo Muriel | 2018 | World Journal of Gastroenterology2018，24，16： | 31 |

| 15 | Clinicopathologic factors and molecular markers related to lymph node metastasis in early gastric cancer显示文摘AIM: To analyze predictive factors for lymph node metastasis in early gastric cancer.METHODS: We analyzed 1104 patients with early gastric cancer(EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mut L homolog 1, p53, epidermal growth factor receptor(EGFR) and human epidermal growth factor receptor 2(HER2) were included. The χ2 test and logistic regression analysis were used to determine clinicopathologic parameters.RESULTS: Lymph node metastasis was observed in 104(9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients(3.8%) were mucosal cancers and 80 patients(16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4(1.7%) for well differentiated tubular adenocarcinoma, 45(11.3%) for moderately differentiated tubular adenocarcinoma, 36(14.8%) for poorly differentiated tubular adenocarcinoma, and 19(8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases(11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases(27.1%) of 406 EGC patients. With multivariate analysis, female gender(OR = 2.281, P = 0.009), presence of lymphovascular invasion(OR = 10.950, P < 0.0001), diameter(≥ 20 mm, OR = 3.173, P = 0.01), and EGFR overexpression(OR = 2.185, P = 0.044) were independent risk factors for lymph node involvement.CONCLUSION: Female gender, tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC. | Eun Hyo Jin Dong Ho Lee Sung-Ae Jung Ki-Nam Shim Ji Yeon Seo Nayoung Kim Cheol Min Shin Hyuk Yoon Hyun Chae Jung | 2015 | World Journal of Gastroenterology2015，21，2： | 30 |
| 16 | Clinical impact of plasma TGF-β1 and circulating TGF-β1 mRNA in diagnosis of hepatocellular carcinoma显示文摘BACKGROUND:Transforming growth factor-β(TGF-β) plays an important role in the regulation of cell growth and differentiation,angiogenesis,extracellular matrix formation,immunosuppression and cancer development. In this study,we investigated the levels of TGF-β1 and TGF-β1 mRNA expression,their relationship with HBV replication,and their diagnostic value for hepatocellular carcinoma(HCC). METHODS:Total RNAs were extracted from HCC samples and matched non-tumor tissues,and from peripheral blood mononuclear cells in HCC patients.TGF-β1 mRNA was amplified by RT-PCR and confirmed by DNA sequencing. The distribution of TGF-β1 expression was assessed by immunohistochemistry.The clinical characteristics were analyzed between TGF-β1 and HBV replication.The diagnostic value of circulating TGF-β1 and TGF-β1 mRNA levels were investigated in HCC patients. RESULTS:The incidence of hepatic TGF-β1 expression was 83.3%in HCC samples,43.3%in the surrounding tissues, 94.7%in the HBV DNA-positive group,and 63.6%in the HBV DNA-negative group.Liver TGF-β1 expression was associated with the degree of HCC differentiation and the status of HBV replication,but not with the size or number of tumors.Circulating TGF-β1 level and incidence of TGF-β1 mRNA were significantly higher in the HCC groupthan in any group of patients with benign liver disease, with a higher sensitivity of 89.5%and a specificity of 94.0% for HCC diagnosis when circulating TGF-β1 levels were >1.2μg/L.No significant correlation was found between TGF-β1 expression and AFP level or tumor size.Combining TGF-β1 level and serum AFP raised the detection rate to 97.4%. CONCLUSIONS:Abnormal expression of hepatic TGF-β1 is associated with the degree of HCC differentiation and HBV replication.Both circulating TGF-β1 and TGF-β1 mRNA can be used as sensitive biomarkers for the diagnosis and prognosis of HBV-induced HCC. | Zhi-Zhen Dong,Deng-Fu Yao,Min Yao,Li-Wei Qiu,Lei Zong,Wei Wu, Xin-Hua Wu,Deng-Bing Yao and Xian-Yong Meng Department of Diagnostics,Research Center of Clinical Molecular Biology,Department of Laboratory Science,and Department of GastroenterologyAffiliated Hospital and Institute of Neurosciences,Nantong University,Nantong 226001,China | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，3： | 27 |
| 17 | Association between vascular endothelial growth factor and metastasis after transcatheter arterial chemoembolization in patients with hepatocellular carcinoma显示文摘BACKGROUND: Hypoxia up-regulates vascular endothelialgrowth factor (VEGF) and stimulates the growth of hepa-tocellular carcinoma (HCC) cells. This study was designedto investigate the association between changes in plasmaVEGF levels after transcatheter arterial chemoembolization(TACE) and HCC progression, especially in relation tometastasis.METHODS: Plasma VEGF levels were measured by quati-tative sandwich enzyme-linked immunosorbent assay(ELISA R&D system). Plasma VEGF levels were measuredbefore, 3 days and 4 weeks after TACE in 30 patients withHCC. The development of metastasis was evaluated at theend of the third month after TACE.RESULTS: The plasma VEGF levels of the 30 patients withHCC were 154.47±90.17 pg/ml. The total plasma VEGFlevels after TACE increased compared with their basal levels(P<0.05), and the plasma VEGF levels had a tendency toincrease in patients with heterogenous uptake of iodizdoiland portal vein thrombosis. Follow-up for six monthsshowed metastatic foci in 20 patients (74%) with increasedplasma VEGF, but none of the patients with decreased plas-ma VEGF developed metastasis.CONCLUSION: Increased plasma VEGF expression is asso-ciated with the development of metastasis in HCC after TA-CE. | Zheng-Ping Xiong, Shu-Ren Yang, Zhao-Yu Liang, En-Hua Xiao, Xiao-Ping Yu,Shen-Ke Zhou and Zi-Shu Zhang, Department of Radiology , Hunan Provincial TumorHospital.

| 18 | Correlation of human epidermal growth factor receptor 2 expression with clinicopathological characteristics and prognosis in gastric cancer显示文摘AIM:To investigate human epidermal growth factor receptor 2(HER2) gene amplification and protein expression in Chinese patients with resectable gastric cancer and the association with clinicopathological characteristics and survival.METHODS:One hundred and ninety-seven gastric cancer patients who underwent curative surgery procedures were enrolled into this study.HER2 gene amplification and protein expression were examined using fluorescence in-situ hybridization(FISH) and immunohistochemistry(IHC) analysis on formalin-fixed paraffinembedded gastric cancer samples from all patients.For scoring,Hofmann's HER2 gastric cancer scoring system was adopted.All cases showing IHC3+ or FISH positiv-ity were defined as HER2 positive.Patient clinicopathological data and survival information were collected.Finally,χ 2 statistical analysis was performed to analyze the HER2 positivity rate amongst the subgroups with different clinicopathological characteristics including;gender,age,tumor location,Lauren classification,differentiation,TNM staging,depth of invasion,lymph node metastases and distant metastasis.The probability of survival for different subgroups with different clinicopathological characteristics was calculated using the Kaplan-Meier method and survival curves plotted using log rank inspection.RESULTS:According to Hofmann's HER2 gastric cancer scoring criteria,31 cases(15.74%) were identified as HER2 gene amplified and 19 cases(9.64%) were scored as strongly positive for HER2 membrane staining(3+),25 cases(12.69%) were moderately positive(2+) and 153 cases(77.66%) were HER2 negative(0/1+).The concordance rate between IHC and FISH analyses was 88.83%(175/197).Thirty-six cases were defined as positive for HER2 gene amplification and/or protein expression,with 24 of these cases being eligible for Herceptin treatment according to United States recommendations,and 29 of these cases eligible according to EU recommendations.Highly consistent results were detected between IHC3+,IHC0/1 and FISH(73.68% and 95.42%),but low consistency was observed between IHC2+ and FISH(40.00%).The positivity rates in intestinal type and well-differentiated gastric cancer were higher than those in diffuse/mixed type and poorly-differentiated gastric cancer respectively(28.57% vs 13.43%,P = 0.0103;37.25% vs 11.64%,P < 0.0001),but were not correlated with gender,age,tumor location or TNM stage,depth of invasion,lymph node metastases and distant metastasis.In poorly-differentiated gastric cancer patients,those without lymph node metastasis showed a higher HER2 positivity rate than those with lymph node metastasis(26.47% vs 7.14%,P = 0.0021).This association was not present in thosepatients with well-differentiated gastric cancer(28.57% vs 43.33%,P = 0.2832).Within our patient cohort,26 cases were lost to follow-up.The median survival time for the remaining 171 patients was 18 mo.The median survival times of the HER2 positive and negative groups were 17 and 18.5 mo respectively.Overall survival was not significantly different between HER2-positive and negative groups(χ 2 = 0.9157,P = 0.3386),but in patients presenting well-differentiated tumors,the overall survival of the HER2-positive group was significantly worse than that of the HER2-negative group(P = 0.0123).In contrast,patients with poorly differentiated and diffuse/mixed subtype gastric cancers showed no significant differences in overall survival associated with HER2.Furthermore,the median survival time of the HER2 positive group did not show any statistically significant differences when compared to the subgroups of gender,age,tumor location,TNM classification,lymph node metastases and distant metastasis.CONCLUSION:Patients with intestinal type gastric cancer(GC),well-differentiated GC and poorly-differentiated GC without lymph node metastasis,may all represent suitable candidates for targeted therapy using Herceptin. | Chao He Xue-Yi Bian Xing-Zhi Ni Dan-Ping Shen Yan-Ying Shen Hua Liu Zhi-Yong Shen Qiang Liu | 2013 | World Journal of Gastroenterology2013，19，14： | 28 |
| 19 | 2型糖尿病肾病患者生长分化因子-15的表达及临床意义显示文摘目的:探讨生长分化因子-15(GDF-15)在2型糖尿病肾病中的表达水平及其临床意义。方法纳入80例2型糖尿病(T2DM)患者,根据Mogensen分期标准,分为正常白蛋白尿组(30例)、微量白蛋白尿组(20例)和大量白蛋白尿组(30例),采用ELISA法测定血浆GDF-15水平。结果大量白蛋白尿组GDF-15水平高于微量白蛋白尿组和正常白蛋白尿组(P均<0.01),分别为1773.9(1099.1-2357.4)pg/ml、864.0(636.1-994.3)pg/ml和704.5(548.8-975.8)pg/ml;微量白蛋白尿组GDF-15水平高于正常白蛋白尿组(P>0.05),且在肾功能轻度受损(60≤肾小球滤过率<90 ml/min/1.73 m2)时GDF-15浓度即有增加,为999.5(769.2-1372.1)pg/ml。偏相关分析显示,血浆GDF-15与糖尿病病程、尿微量白蛋白(mAlb)、尿素氮(BUN)及肌酐(sCr)呈正相关(r=0.246,0.493,0.390,0.471,P均<0.05),与估计的肾小球滤过率(eGFR)及血浆白蛋白(Alb)呈负相关(r=-0.438,-0.397,P均<0.01)。多元线性回归分析提示较高水平的GDF-15为mAlb增加的独立危险因素。在对肾功能受损(eGFR<90 ml/min/1.73 m2)的诊断中,GDF-15和mAlb的曲线下面积分别为0.801和0.717,GDF-15曲线下面积大于mAlb(P<0.05)。当733.78 pg/ml作为GDF-15诊断肾功能受损的临界值时,敏感性和特异性达到最佳,分别为88.1%和58.1%。结论GDF-15在2型糖尿病肾病不同临床阶段有不同程度的增高,不但与mAlb、eGFR有良好的相关性,而且是mAlb增加的独立危险因素,故在2型糖尿病肾病的早期诊断、病情评估及预测其疾病转归方面具有一定的应用价值。 | 李慧 高方 薛耀明 钱毅 | 2014 | 南方医科大学学报2014，34，3： | 27 |
