E2/E2, E2/E3 , E2/E4, E3/E3 and E3/E4, and their frequencies were 0.075,0.060, 0.164, 0.642 and 0.060, respectively. The frequencies of 3 alleles, E2, E3 and E4, in Huis and Hans were 0.021, 0.947, 0.032 and 0.187, 0. 702, 0.112, respectively. The results showed that difference in frequencies of genotypes and alleles of Huis and Hans was very significant (both P
6.An in vitro study of fluoride release rate of F-containing thermoplastic resina
Journal of Practical Stomatology 2000;0(05):-
Objective:To observe the fluoride release rate of F-containing thermoplastic resina,trying to find a suitable concentration of fluoride in thermoplastic resina to prevent caries in base teeth of partial denture restorations.Methods:Na2(PO3)F-containing thermoplastic resina,respectively 0,10%,15%,20% and 25%(w/w)in concentration were cut into three 1 g blocks and immersed in 100,200 and 500 ml deionized water.These composite resins in 100 ml and 200 ml solutions were replaced every 1,2,3,6,9,16 days(every 7 days after that)until two months later,500 ml solution was reserved after 3,6,9 days every 7 days later until two months,2 ml of which were reserved every time.The fluoride release rates of these thermoplastic resina were tested by potentiometry.Results:All thermoplastic resina containing different concentrations of fluoride could release F-during the period of 65 days.Conclusion:When Na2(PO3)F is mixed in thermoplastic resina,it releases fluoride slowly.Thermoplastic resina containing 15% F-has higher release rates of fluoride.
7.Efficacy and safety of docetaxel plus apatinib as a second-line treatment for advanced non-squamous non-small cell lung cancer
Chinese Journal of Clinical Oncology 2017;44(11):544-546
Objective:To observe the efficacy and safety of docetaxel plus apatinib as a second-line treatment for advanced non-squa-mous non-small cell lung cancer. Methods:From February 2015 to August 2016, 39 eligible patients were randomly assigned to experi-mental arm (19 cases) and control arm (20 cases). Patients in the experimental arm received 60 mg/m2 d1 docetaxel and 500 mg d1-21 apatinib for a 21-day cycle until disease progression or unacceptable toxicity occurred. Patients in the control arm received chemother-apy only. Disease control rate (DCR), incidence of adverse event, and progression-free survival (PFS) were analyzed. Results:The dis-ease control rates (DCR) in the experimental and control arms were 63.2% and 30.0%, respectively, with statistical difference (P=0.039). The experimental arm experienced many grades 3-4 hematologic adverse events with statistical difference (P=0.032). The medi-an PFS values were 5.6 months (95% CI=4.8-6.3) and 3.0 months (95% CI=1.8-4.1) with statistical difference (P=0.04). Conclusion:Docetaxel plus apatinib can be delivered safely with careful monitoring for the treatment of advanced non-squamous non-small cell lung cancer, and this treatment can significantly improve the DCR and PFS.
