BACKGROUND:Nano-hydroxyapatite as a surface modification material that is bonded to the surface of the zirconia ceramics upon sintering at high temperature can improve bone-inducing activity and bone bonding strength of the zirconia ceramics. Moreover, the sintering temperature is crucial for performance and bonding of the composite. OBJECTIVE:To detect the shear strength of nano-hydroxyapatite ceramics coating bonded to zirconia ceramics at different sintering temperatures. METHODS:Nano-hydroxyapatite slurry was prepared using sol/gel technology. Thereafter, 20 zirconium green bodies were coated with nano-hydroxyapatite slurry and randomly divided into four groups. Then, the specimens were put into non-pressure sintering furnace and sintered at 1 300, 1 400, 1 500, and 1 550℃, respectively. At last, we measured the shear strength of al the specimens after sintering by universal testing machine, and analyze the type of fractures. RESULTS AND CONCLUSION: With the rising of sintering temperature, the shear strength of the specimens was gradualy increased, and there were significant differences between the four groups [(4.04±1.19), (6.60±0.95), (16.51±1.93), (80.47±19.31) MPa,P < 0.05]. Within the scope of 1 550℃, the sintering temperature was positively relative to the shear strength of specimens. These findings indicate that in the certain temperature range, the higher the sintering temperature, the greater the shear strength of the bonding interface between zirconia and nano-hydroxyapatite. When the sintering temperature is 1 550℃, the shear strength of the bonding interface is the highest.

Objective:To evaluate efficacy and safety of multiple-dose tropisetron plus dexamethasone (DXM) versus palonosetron plus DXM for chemotherapy-induced nausea and vomiting. (CINV) in patients received multiple day-based highly emetogenic chemotherapy. Methods:Cancer patients who were receiving multiday-based highly emetogenic chemotherapy were randomly assigned to AB or BA groups. A randomized, cross self-control ed method was applied. Patients in AB group received palonosetron (0.25 mg) 30 min before chemotherapy on day 1 and 3 or additional day 5 in the first cycle;and with tropisetron (5 mg) 30 min before chemotherapy on day 1, 2, and 3, or sup-plementary days (day 4 and 5) in the second cycle. Patients in BA group were treated with tropisetron in the first cycle and with palonosetron in the second cycle. Tropisetron and palonosetron were administered with DXM (10 mg) on day 1, followed by additional doses (5 mg) on days 2 to 5. Palonosetron group comprised patients in the AB group in the first cycle and BA group in the second cycle, whereas tropisetron group included patients in the AB group in the second cycle and BA group in the first cycle. Efficacy and safety of tropisetron versus palonosetron in preventing CINV were evaluated. Results:Ninety-one patients were included in analyses. At day 3, 4, and 5, incidence rates of nausea in the palonosetron group reached 28.6%, 30.8%, and 24.2%, respectively, and those of the tropisetron group totaled 42.8%, 47.3%, and 39.6%, respectively (P<0.05). At day 4, 5, and 6, incidence rates of vomiting in the palonosetron group measured 28.6%, 18.7%, and 5.5%, respectively, and those of the tropisetron group reached 42.9%, 34.1%, and 14.3%, respectively (P<0.05). From day 4 to day 5, day 6 to day 7, and day 1 to day 7, the palonosetron group yielded significantly lower incidence rates of nausea and vomiting than tropisetron group (P<0.05). Rate of rescue treatment in the palonosetron group was lower than that in tropisetron group (13.2%vs. 24.2%, P=0.057). No statistical difference in toxicities was observed between the two groups. Conclusion:Palonosetron plus DXM features better efficacy than that of tropisetron plus DXM against delayed CINV induced by multiple day-based highly emetogenic chemotherapy, which was well tolerated in the two treatments.

Objective To evaluate the feasible cervical cancer screening strategies in rural China. Methods The study was based on the health industry scientific research project of National Health Commission in 2015, cervical cancer screening technology and demonstration research suitable for rural areas in China, we collected health economics and epidemiological parameters and established the unscreening model and screening model with Treeage Pro 2011 software. Combining with the data acquired from site investigation, including population screening, treatment-related clinical materials and cost data, we simulated the occurrence and the development of cervical cancer of rural women in China under different screening and intervention programs and predicted the screening effects [cumulative incidence, cumulative risk of disease, life years and quality adjusted life years (QALY), gains] and costs after 20 years, and using health economic evaluation analysis (cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis). Screening programs included five screening strategies [visual inspection with acetic acid/lugol's iodine (VIA/VILI), careHPV, ThinPrep cytology test (TCT), careHPV+TCT, careHPV+VIA/VILI] and three screening intervals (1-year, 3-year, 5-year), a total of fifteen screening programs. Results Compared with no screening, fifteen screening programs reduced the cumulative incidence by 22.65%-51.76%. Compared with TCT or VIA/VILI, for the same screening interval, the reduced cumulative incidence, the amounts of life-year saved and QALY and benefits gained of careHPV were the highest. The cost-effectiveness ratios of these screening programs ranged (0.44-3.24)×104 Yuan per life-year saved, cost-utility ratios ranged (0.15-1.01)×104 Yuan per QALY, benefit-cost ratios ranged 7.73-59.10. The results of incremental cost-effectiveness ratios showed that VIA/VILI every five years, VIA/VILI every three years, careHPV every five years, careHPV every three years and careHPV every year were dominant programs. Conclusions VIA/VILI screening is cost-effective, careHPV is slightly more expensive but more effective. In rural China, careHPV screening every five years could be recommended. This study provides a basis for the determination of cervical cancer screening methods feasible for rural areas in China.
