OBJECTIVE: To investigate the effect of Compound danshen dripping pills on cytochrome CYP1A2 activity for reference of clinical rational drug use. METHODS: The contents of four major metabolites of Caffeine, i.e. 5-acetylamino-6-formylamino-3-methyluracil(AFMU),1-methylxanthine(1X), 1-methyluric acid(1U) and 1, 7-dimethyluricacid (17U) in the urine before and after oral administration of Compound danshen dripping pills were determined by RP-HPLC. The activity of cytochrome CYP1A2 was derived from the ratio of (AFMU+1X+1U)/17U. RESULTS: The average activity of CYP1A2 was 4.20?1.54 before medication, which stood at 4.26?1.95 at 14 days and 4.35?1.26 at 28 days after medication, up 1.42% and 3.57%, respectively, yet there was no significant difference after medication as compared with before medication. CONCLUSION: No significant difference was noted on CYP1A2 activity after oral medication of Compound danshen dripping pills, nor does it modify the efficacy of the concurrent drugs that metabolized by CYP1A2.

Methods Thawed UCB MNC were cultured 24 h or 14 d with various concentration of APS (0,50,100,200,and 400 ?g/mL) or with APS and HGFs. The MNC counting assay,typan blue exclusion assay,colorimetric MTT assay for cell proliferation,CFU-Mix colong-forming assay,and flow cytometry for CD34+ cell rate were detected. Results After adding certain concentration APS in thawed UCB cells,the number of MNC,the rate of trypan blue exclusion,the proliferation of MNC,and the colony production of CFU-Mix were significantly enhanced (P

Objective:To prepare and characterize chitosan/hyaluronic acid (CS/HA) nanoparticles for miRNA-148b (miR-148b)delivery.Methods:CS/HA/miR-148b nanoparticles were prepared.The particle size,zeta potential,morphology were investigated by nano laser granulometer and TEM respectively.The encapsulation efficiency of CS/HA nanoparticles was evaluated by gel retarding analysis.The cytotoxicity and transfection efficiency of CS/HA/miR-148b nanoparticles on rat bone marrow mesenchymal stem cells (MSCs) were evaluated by CCK-8 assay,transfection assay and FCM respectively.Results:The CS/HA/miR-148b nanoparticles were discrete spherical particles with the diameter of 160 to 370 nm and zeta potential of + 15 to +41 mV.N/P ratio at 20∶1 of the nanoparticles showed the optimum encapsulation efficiency for miR-148b.CS/HA/miR-148b nanoparticles exhibited no cytotoxicity to MSCs and could deliver miR-148b to the MSCs at high transfection efficiency.Conclusion:CS/HA/miR-148b nanoparticles are safe and effective for miR-148b delivery into MSCs.

Objective:To investigate the protein expression levels of breast cancer metastasis suppressor 1 (BRMS1) and Con-nexin 43 (Cx43) in thyroid cancer and their correlation with clinicopathologic parameters. Methods:Immunohistochemistry Streptavi-din-Peroxidase method was used to detect the BRMS1 and Cx43 protein expression in 195 tissue samples, including 90 cases with thy-roid carcinoma, 45 cases with thyroid adenoma, 30 cases with nodular goiter, and 30 cases with normal thyroid glands. Results:The positive rates of BRMS1 and Cx43 expression was 56.7%(51/90) and 41.1%(37/90) in thyroid carcinoma, respectively, which are sig-nificantly lower than the rates in thyroid adenoma, nodular goiter, and normal thyroid gland tissues (P<0.001). Of the three pathological types of thyroid cancer, the positive expression rate of Cx43 was 61.9%in papillary carcinoma, 27.8%in medullary carcinoma, 27.3%in follicular carcinoma, and 12.5%in undifferentiated carcinoma. Statistical differences in the BRMS1 expression among papillary car-cinoma and the other pathological types were also noted. Unlike the patients without lymph node metastasis, the positive expression of BRMS1 and Cx43 proteins were both significantly low among patients suffering from nodal metastasis. Subgroup analysis shows that the positive expression of BRMS1 and Cx43 protein gradually decreased with TNM staging. In addition, a positive correlation was ob-served between the BRMS1 and Cx43 protein expression (r=0.494, P=0.032). Conclusion:The decreased expression of BRMS1 and Cx43 proteins is significantly correlated with the metastasis of thyroid cancer and malignant grade. The combined detection of the two proteins can be ideal biomarkers for judging the prognosis of thyroid carcinoma.
