| 7 | The intracellular mechanism of alpha-fetoprotein promoting the proliferation of NIH 3T3 cells显示文摘AIM The existence and properties of alpha-fetoprotein (AFP) receptor on the surface of NIH 3T3 cells and the effects of AFP on cellular signal transduction pathway were investigated. METHODS The effect of AFP on the proliferation of NIH 3T3 cells was measured by incorporation of 3H-TdR. Receptor-binding assay of 125I-AFP was performed to detect the properties of AFP receptor in NIH 3T3 cells. The influences of AFP on the [cAMP]i and the activities of protein kinase A (PKA) were determined. Western blot was used to detect the change of K-ras P21 protein expression. RESULTS The proliferation of NIH 3T3 cells treated with 0-80 mg/L of AFP was significantly enhanced. The Scatchard analysis indicated that there were two classes of binding sites with KD of 2.722×10-9M (Bmax=12810 sites per cell) and 8.931× 10-SM (Bmax=l19700 sites per cell) respectively. In the presence of AFP (20 mg/L), the content of cAMP and activities of PKA were significantly elevated . The level of K-ras P21 protein was upregulated by AFP at the concentration of 20 mg/L. The monoclonal antibody against AFP could reverse the effects of AFP on the cAMP content, PKA activity and the expression of K-ras p21 gene. CONCLUSION The effect of AFP on the cell proliferation was achieved by binding its receptor to trigger the signal transduction pathway of cAMP-PKA and alter the expression of K- ras p21 gene. | MENG SEN LI, PING FENG LI, FBI YI YANG, SHI PENG HE, Guo GUANG DU, GANG LI1 Department of Biochemistry and Molecular Biology, 2 Department of Biophysics, Health Science Center, Peking University, Beijing 100083, China | 2002 | Cell Research2002，12，2： | 27 |

| 9 | Effect of Sancaijiangtang on plasma nitric oxide and endothelin-1 levels in patients with type 2 diabetes mellitus and vascular dementia:a single-blind randomized controlled trial显示文摘OBJECTIVE: To observe the effect of Sancaijiangtang powders on plasma nitric oxide and endothelin-1 levels. We sought to identify the common pathological link and mechanism of action for Traditional Chinese medicine in type 2 diabetes mellitus and vascular dementia,and to explicate the material basis for treating the different diseases with the same method in Traditional Chinese Medicine.METHODS: In total,168 patients with type 2 diabetes mellitus and vascular dementia were enrolled in the study,and randomly divided into two groups by simple randomization. Patients in the treatment group received oral Sancaijiangtang powders with pioglitazone hydrochloride three times daily,while patients in the control group received pioglitazone hydrochloride alone. The treatment course was for12 weeks. Mini-mental state examinations(Chinese version) and Montreal Cognitive Assessments(Beijing version) were performed,and fasting plasma glucose,fasting insulin,hemoglobin A1 c,homeostasis model assessment of insulin resistance,plasma nitric oxide and endothelin-1 levels were measured before and after the treatment.RESULTS: The post-treatment levels for all measurements in both groups were better than pre-treatment levels(P < 0.05). The post-treatment levels for all measurements in the treatment group were better than the levels measured in the control group(P < 0.05).CONCLUSION: Type 2 diabetes mellitus and vascular dementia have common pathological mechanisms for insulin resistance and endothelium dysfunction. Sancaijiangtang powders could improve the release of nitric oxide and inhibit the secretion of endothelin-1. Therefore,the material basis exists for treating the different diseases with the same method in Traditional Chinese Medicine. | Guo Qiang Cao Wenzhai Zhao Huan Zhu Yuxia Yang Dongdong Zhong Sen Chen Qiu | 2015 | Journal of Traditional Chinese Medicine2015，35，4： | 24 |

| 11 | Soil Erosion and Vegetation Succession in Alpine Kobresia Steppe Meadow Caused by Plateau Pika——A Case Study of Nagqu County, Tibet显示文摘This paper evaluated the impacts of mounds created by the plateau pika (Ochotona curzoniae) on the vege- tation composition, structure, and species diversity of an alpine Kobresia steppe meadow in Nagqu County, Tibet Autonomous Region, China. Based on mound height or the depth of erosion pit, we defined five stages of erosion and compared the floristic features of communities at these stages with those in undisturbed sites. In the study area, the mounds and pits covered up to 7% of the total area. Lancea tibetica, Lamiophlomis rotata, and Potentilla bifurca were the dominant species in erosion pits, and Kobresia pygmaea, the dominant species in undisturbed sites, became a com- panion species in eroded areas. In the process of erosion, the original vegetation was covered by soil ejected by the pika, then the mounds were gradually eroded by wind and rain, and finally erosion pits formed. The vegetation coverage in- creased with increasing erosion stages but remained significantly lower than that in undisturbed sites. Improved coverage eventually reduced soil erosion, and pit depth eventually stabilized at around 20cm. Aboveground biomass increased with increasing erosion stage, but the proportion of low-quality forage reached more than 94%. The richness index and Shannon-Wiener index increased significantly with increasing erosion stage, but the richness index in mound and pit areas was significantly lower than that in undisturbed sites. | WEI Xinghu LI Sen Yang Ping Cheng Huaishun | 2007 | Chinese Geographical Science2007，17，1： | 22 |

| 18 | A Review on Cable-driven Parallel Robots显示文摘Cable-driven parallel robots(CDPRs) are categorized as a type of parallel manipulators. In CDPRs, flexible cables are used to take the place of rigid links. The particular property of cables provides CDPRs several advantages, including larger workspaces, higher payload-to-weight ratio and lower manufacturing costs rather than rigid-link robots. In this paper, the history of the development of CDPRs is introduced and several successful latest application cases of CDPRs are presented. The theory development of CDPRs is introduced focusing on design, performance analysis and control theory. Research on CDPRs gains wide attention and is highly motivated by the modern engineering demand for large load capacity and workspace. A number of exciting advances in CDPRs are summarized in this paper since it is proposed in the 1980 s, which points to a fruitful future both in theory and application. In order to meet the increasing requirements of robot in different areas, future steps foresee more in-depth research and extension applications of CDPRs including intelligent control, composite materials, integrated and reconfigurable design. | Sen Qian Bin Zi Wei-Wei Shang Qing-Song Xu | 2018 | Chinese Journal of Mechanical Engineering2018，31，4： | 19 |
| 19 | Incidence of infectious complications is associated with a high mortality in patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘BACKGROUND In China,hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is the most common liver failure characterized by serious clinical syndromes of liver decompensation with a very high mortality.Bacterial and/or fungal infections are the most common complications that are associated with high short-term mortality.Bacterial translocation from the intestine,impaired hepatic clearance,and immune paralysis of circulating immune cells are thought to contribute to infectious complications in liver failure.The control of bacterial and fungal infections is the key to improving HBV-ACLF outcomes.Active prevention,early diagnosis,and timely treatment of bacterial and fungal infections are essential for treating HBV-ACLF.AIM To investigate the frequency and role of bacterial and fungal infections in patients with HBV-ACLF.METHODS Patients with HBV-ACLF hospitalized at Taihe Hospital,Hubei University of Medicine from January 2014 to December 2017 were retrospectively enrolled.Patient-related information was retrieved from the hospital case database,including general information,blood biochemistry,complications,etc.According to the occurrence of secondary infection or not,the patients were divided into an infection group and a non-infection group.The sites,types,and incidences of bacterial and fungal infections and the influence of infections on the prognosis of HBV-ACLF were statistically analyzed.The risk factors for infections were assessed by unconditional logistic regression.RESULTS There were 174 cases of HBV-ACLF that met the enrollment criteria,of which 114 (65.52%) were diagnosed with infectious complications.Infections occurred in the abdominal cavity (87 cases),respiratory tract (51 cases),urinary tract (18 cases),and biliary tract (10 cases).Patients with infectious complications had a significantly higher 28-d mortality (70.18%,80/114) than those without (40.00%,24/60)(70.18% vs 40.00%,P < 0.05).And patients with infectious complications had a much higher incidence of non-infectious complications (54.39%,62/114)(54.39% vs 15.00%,P < 0.05),leading to an extremely high 28-d mortality of 88.71%(55/62)(P < 0.05).The grade of liver failure,period of hospital stay ≥ 30 d,age ≥ 45 years,and percentage of neutrophils > 70% were identified as risk factors for infectious complications.CONCLUSION The high incidence of infectious complications in patients with HBV-ACLF is associated with severity and deterioration of the disease and may contribute to the extremely high mortality of these patients. | Chen Wang De-Qiang Ma Sen Luo Chuan-Min Wang De-Ping Ding You-You Tian Kang-Jian Ao Yin-Hua Zhang Yue Chen Zhong-Ji Meng | 2019 | World Journal of Clinical Cases2019，7，16： | 18 |
