Chinese Journal of Primary Medicine and Pharmacy 2014;(10):1463-1465
Objective To explore the correlation of serum ferritin (SF),fibrinogen(FIB) and D-dimer levels in patients with small vessel disease(SVD).Methods 359 patients with SVD were selected,including 186 patients with lacunar infarction ( LI) and 173 patients with leukoaraiosis ( LA) .176 healthy controls were enrolled in this study as control group.The SF,FIB and D-dimer concentrations were measured by radioimmunoassay method and Clauss method respectively .Results The serum levels of SF , FIB and D-dimer in SVD patients were significantly higher than those in the controls [(171.82 ±156.28)μg/L vs (100.37 ±70.11)μg/L,(3.27 ±0.93) g/L vs (2.97 ± 0.88)g/L,(1.10 ±1.06)mg/L vs (0.83 ±0.55)mg/L](all P<0.05).Compared with LI subgroup,the levels of SF,FIB and D-dimer were higher in LA subgroup [(185.22 ±108.55)μg/L vs (159.36 ±89.69)μg/L,(3.32 ± 0.86)g/L vs (3.23 ±0.99)g/L,(1.29 ±1.17)mg/L vs (1.03 ±0.80)mg/L],but the differences were not signifi-cant(all P<0.05).Multivariate regression analysis revealed that by comparison to the reference quartile ,the odds ra-tio (95%CI) for SVD patients in the higher quartile (SF>151.16μg/L,D-Dimer>1.02 mg/L) were 3.444(95%CI=2.097-5.158,P<0.001) and 1.767(95%CI=1.114-2.803,P=0.016),respectively after multivariable ad-justment.Conclusion The increased levels of SF ,FIB and D-dimer are closely related with SVD .FIB and D-dimer might come to be attractive approaches to prevent the progress of SVD .
4.The clinical value of liquid tumor biomarker detection for breast cancer
China Oncology 2014;(8):636-640
Circulating tumor markers have been paid more attention in the application of the treatment for breast cancer, the level of which has extended from protein to gene, including traditional tumor markers, HER-2 extracellular domain, circulating tumor cells, circulating tumor DNA (ctDNA), circulating RNA (ctRNA) and so on. As “liquid detection”, the detection of circulating tumor markers with real-time dynamic, easy operation, good reproducibility and other advantages are widely used in aiding early diagnosis, determining prognosis, prospectively predicting response or resistance to speciifc therapies, surveillance after primary surgery, and monitoring therapy in patients with advanced disease, The further study of circulating tumor markers may contribute to patient’s individual treatment.
5.Determination of Terbutaline Sulfate and Its Combination with β_2 Adrenergic Receptor in Erythrocyte Membrane by High Performance Liquid Chromatography
Chinese Journal of Analytical Chemistry 2010;38(3):377-380
A high performance liquid chromatographic method with hypersil C_(18) column, 0.020 mol/L potassium dihydrogen phosphate solution(which contains 0.25% triethylamine, pH 5.1)-methanol(20∶ 80, V/V) as mobile phase and fluorescence detection with 280 nm as excitation wavelength and 320 nm as emission wavelength has been developed for the determination of terbutaline sulfate and propranolol hydrochloride in Erythrocyte suspensions. Erythrocyte surface receptor oscillating reacted 1 h with terbutaline in 37 ℃ water bath. Free terbutaline and propranolol were separated from the membrane receptor-binding complex through 1500 r/min centrifugal in 5 min. The linear range was 0.010-3.000 mg/L in Alsever's solutions and the correlation coefficients were 0.9999 and 0.9998. The relative standard deviations(RSDs) of terbutaline and propranolol were 0.8% and 1.2%, respectively. The limits of detection(LODs) of both were 1.00 and 3.00 mg/L. This simple, safety and sensitive method was suitable for the determination of terbutaline and propranolol in erythrocyte suspensions and for the study of receptor-ligand binding.
6.Sulfotransferase and breast cancer
Journal of International Oncology 2010;37(8):591-593
Sulfotransferase (SULT) enzymes play important roles in the biosynthesis of estrogen.These enzymes catalyze the sulfation of estrogens to form biologically inactive molecules. Several studies have shown that Arg213His polymorphism in SULT1A1 gene may be a risk factor for breast cancer. In addition, a low mRNA expression of SULT has been significantly associated with reduced recurrence and improved overall survival in patients with estrogen receptor (ER)-positive tumors. Furthermore, SULT may be a crucial factor in the response to tamoxifen treatment. As an important part of estrogen synthetic pathways, SULTs are closely re lated to breast cancer.

Chinese Journal of Primary Medicine and Pharmacy 2010;17(2):179-181
Objective To investigate good nutritional measurements of CKD patients.In order to diagnose malnutrition early in CKD patients.Methods Clinical data of 125 CKD patients have been collected.The glomerular filtration rate(GFR)was estimated from the modification of diet in renal disease(MDRD).According to the results of GFR,all CKD patients were divided into five groups.The levels of biochemical markers were assayed.At the same time,bioelectrical impedance analysis(BIA)were measured.We analyzed the relationship between nutritional parameters and GFR.Results According to SGA,malnutrition rate in fifth CKD stage is 29%.Impedance of leg is significantly correlated to GFR in 1kHz,50kHz and 500kHz,impedance of truck is also significantly correlated to GFR in 50kHz and 500kHz.The values of impedance reduced with the decreasing of GFR.Conclusion SGA and BIA all can be used to evaluate nutritional status of CKD patients.BIA is a more sensitive method to detect early malnutrition and may be useful in monitoring nutrition changes in CKD patients.
