1.Effects of combination treatment with SAHA and TRAIL on ER positive breast cancer cell MCF-7
Chinese Pharmacological Bulletin 2016;(2):223-228
Aim To investigate the effects of com-bined treatment of SAHA and TRAIL on human breast cancer ER positive cell line MCF-7 . Methods MCF-7 cells were treated with SAHA and/or TRAIL. The inhibitory rates were detected by real-time cell prolifer-ation assays. Morphology changes of MCF-7 cells were observed through time-lapse live cell imaging acquisi-tion. Results Real-time cell proliferation assays showed that the anti-tumor efficacy of SAHA was sig-nificantly enhanced in combination with TRAIL. The results of time-lapse live cell imaging acquisition dem-onstrated that, with treatment of SAHA and TRAIL, the growth inhibition of MCF-7 cells was more obvious than that of in TRAIL or SAHA treatment alone. Con-clusion The combination treatment of SAHA and TRAIL has a synergistic effect of growth inhibition on breast cancer MCF-7 cells.

4.Venous thrombosis around internal jugular venous indwelling catheter in hemodialysis patients
Chinese Journal of Nephrology 2009;25(1):1-4
Objective To investigate the prevalence, characteristics and risk factors of superior vena cava and auxiliary branchs thrombosis in hemodialysis patients with internal jugular venous indwelling catheter. Methods A total of 43 cases on hemodialysis (HD) with indwelling short-term catheter in internal jugular vein from June to December in 2007 were enrolled in this study. The clinical data and biochemical indicators were collected to investigate the prevalence, characteristics and risk factors of venous thrombosis around indwelling catheter, such as, superior vena cava and auxiliary branehs in these patients. Results Short-term double Iumen internal jugular venous catheter were placed in 43 HD patients. Different degrees of central vein thrombosis were found in 21 of the 43 HD patients (48.8%). The ratio of thrombosis in jugular vein, brachiocephalic vein, subclavical vein and uperior vena cava was 100% (21/21), 28.6% (6/21), 23.8%(5/21) and 19.0%(4/21), respectively. Ten of the 21 HD patients (47.6%) with central vein thrombosis presented clinical symptoms. Five cases developed edema of the upper extremity, 2 cases had new-onset symptom's pulmonary embolism, and 3 eases developed blood overflowed from inlet port of circum-catheter. The ratio of diabetes mellitus, malignant tumor, the prevalence of increased level of serum lipoprotein a and plasma homocysteic acid were significantly higher in the HD patients with central vein thrombosis than that in those without central vein thrombosis. The odds ratio of diabetes mellitus, malignant tumor, high serum lipoprotein a and high plasma homocysteic acid was 5.758, 4.750, 6.967 and 8.533, respectively. Conclusions The prevalence of central vein thrombosis in HD patients with short-term indwelling catheter in internal jugular vein is quite high. Its clinical symptom is insidious but dangerous. Diabetes mellitus, malignant tumor, high serum lipoprotein a and high plasma homocysteic acid may be the important risk factors of central vein thrombosis in above HD patients.
5.Recent progress in the improvement of the coupling efficiency of "difficult sequences" in peptide synthesis
Acta Pharmaceutica Sinica 2007;42(2):111-117
Even though chemistry is now in place that potentially allows high coupling efficiencies to be attained, successful coupling is usually a challenge when so-called "difficult sequences" is encountered in peptide synthesis. Some factors that affect the coupling efficiency have been discussed and related methods to overcome those obstacles have been introduced in present review. All suggestions proposed here are valuable and also feasible to improve the coupling completeness in both liquid-phase or solid-phase peptide synthesis.
6.Strategies for novel protein biomarker identification through multiple reaction monitoring mass spectrometry
Chinese Journal of Laboratory Medicine 2011;34(6):484-488
With the development of proteomic technologies, large numbers of putative biomarkers have been screened out but few of them are put into the clinical application.Recently, MRM-MS based approaches and strategies have aroused extensive concern in domestic and overseas clinical laboratory community because of their cost-efficiency, time-saving, high analytical sensitivity and accuracy.MRM-MS based approaches, especially SISCAPA, may gradually become a key technology for the protein biomarker research in the near future.In this review, the bottleneck existing in the field of protein biomarkers research, and features as well as applications of MRM-MS are discussed and the future trend of research is prospected.
