1.Management of biomedical research at the university of cambridge: Implications for China
Chinese Journal of Medical Science Research Management 2017;30(1):2-5,20
In China,the Chinese scientist TU Youyou,winner of the Nobel Prize in Physiology or Medicine and her findings of artemisinin discovered during the 1970s triggered a lot of discussion on developing a biomedical research management strategy in the new era.Traditional management has faced many challenges in the era of Big Science.The University of Cambridge has remarkable achievements in biomedical research and set up an effective management system.Based on the introduction and observations from Cambridge,this article proposes strategies for advancing research management in Chinese universities in our own context.
2.Latest advance in the biological behavior of gastrointestinal stroreal tumors
International Journal of Surgery 2008;35(7):486-489
Gastrointestinal stromal tumors are the most common mesenchymal neoplasms deriving from the gastrointestinal tract.The prediction of its biological behavior has become a new hot spot of the research.This article reviewed the studies on predicting the biological behavior of gas trointestinal stromal tumors.

Objective To evaluate whether the prognosis of 6 months major adverse cardiac events(MACE)after acute myocardial infarction,and the reperfusion state of myocardial tissue are related to the white blood cell(WBC)count in elderly patients.Methods A total of 101 consecutive patients aged≥60 years(mean age 70?6 years)who had a primary percutaneous coronary intervention as their first-line therapy for ST-elevation myocardial infarction(STEMI)were enrolled, and both their WBC count on admission and ST-monitoring were available.A prospectively defined cut-off value of WBC count was 10,000/?l,a cut-off 50% measured after 60 min was used as ST -segment resolution(STR).Results The high WBC count group(n=48)showed the significantly higher(52.1% vs 22.6%,P<0.01)incidence of 6 months major adverse cardiac events(MACE)than did the,low WBC count group(n=53).The low WBC count group had 45 patients with STR≥50%, high WBC count group had 23 patients with STR≥50%,STR after PCI was significantly different between the 2 groups(P<0.01).Conclusions The WBC count is a predictor of the adverse outcome in elderly patients with STEMI.Furthermore,elevation in WBC count is associated with poor myocardial microcirculatory reperfusion.
4.A modified rabbit model of gouty knee arthritis
Chinese Journal of Tissue Engineering Research 2017;21(24):3881-3887
BACKGROUND:An ideal animal model is important for studying gouty arthritis. However, a lack of perfect animal model of gouty arthritis delays the progress in searching for a novel drug and treatment method. OBJECTIVE:To evaluate the effectiveness of the modified rabbit model of gouty knee arthritis. METHODS:New Zealand white rabbits were selected and randomly divided into four groups. Except bIank control group received no intervention;the rabbit greater omentum was removed, which was wrapped with nothing (sham operation group), impIanted with 0.1 g/L monosodium urate crystal suspension (conventionaI group), or 100 mg/kg monosodium urate crystal (modified group) into the suprapatellar cyst of the rabbit right knee. The swelling degree, motor function, and inflammatory response of the knee joint were observed at 1, 2 and 3 days, 1, 2, 3, and 4 weeks after modeling to evaluate the advantages and disadvantages of the modified model. RESULTS AND CONCLUSION:The movement function in the modified group was significantly decreased within

As a main cellular organelle for bioenergy production , the mitochondrion plays a pivotal role in aerobic respiration , substance metabolism , oxidative stress , apoptosis and calcium homeostasis .Increasingly studies have shown a close relationship between mitochondrial dysfunction and cancer .Mitochondrial metabolic disturbance , reactive oxygen species ( ROS ) increase, mitochondrial gene mutation , calcium overload and abnormal apoptosis can influence tumorigenesis , growth, invasiveness and metastasis of multiple tumors .We aimed to summarize the mechanisms and influences of mitochondrial dysfunction on cancer .

Objectives:The effects of human growth hormone (hGH) on cell cycle kinetics were studied in human colonic cancer cell line, LS-174-T cell. Methods: The cells were cultured in RPMI-1640 medium for 24 hours with hGH at concerntration of 50, 100, 200 ng/ml with or without cisplatin. Cell cycle kinetics was analyzed by flow cytometry. Results: The significant effects of hGH on cell cycle kinetics were found in the cell line. Percentage of S phase increase (P<0.01) and percentage of G2/M phase decreased (P<0.01).DNA Index (DI) didn't increase.The cells had a lot of apoptosis and percentage of S phase decreased (P<0.01) with addition of cisplatin. Conclusions: In vitro hGH may induce the proliferation of colonic cancer cells. Cisplatin may suppress the stimulatory effects of hGH on S phase and increase the apoptosis of colonic cancer cells.
