Objective To evaluate the osteocompatibility of poly(D,L lactic acid)/ hydroxyapatite/decalcified bone matrix (PDLLA/HA/DBM) and to compare the osteocompatibility with that of PDLLA and DBM. Methods The isolated human osteoblasts from the femoral head of patients were inoculated onto PDLLA/HA/DBM, PLA, and DBM. The interface between biomaterial and osteoblasts was investigated with phase contrast microscope and scanning electron microscope. Results Osteoblasts were attached tightly to the surface of biomaterial with an arched structure and had normal morphology. The extracellular collagenous matrix covered the surface of biomaterial and packed the granules of biomaterial completely. Conclusion PDLLA/HA/DBM can form osteointegrated interface at the early stage with good biocompability.

Objective To study the effects of PDLLA/HA/DBMV biomaterials on cell proliferation by comparison of polyactic acid (PDLLA) and decalcified bone matrix (DBM) so as to evaluate the biocompatibility of the biomaterials at the cell level. Methods The isolated third generation human fetal osteoblasts (suspension, 3.5?10 5/ml) were inoculated onto the biomaterials of PDLLAHA/DBM, PDLLA, and DBM for 1, 2, 3, 5, and 7 d. Proliferation rates of cells on different materials were determined by flow cytometry. Results The osteoblast proliferation rate on PDLLA/HA/DBM was higher than that on PLA and DBM. Conclusion PDLLA/HA/DBM is compatible for the growth of osteoblasts.

Objective: To observe the influence of sot alol on the QT dispersion in patients with atrioventricular accessory pathways u nderwent radiofrequency catheter ablation (RFCA). Methods: Thirt y-six patients were divided into 2 groups by random. One was the drug group(18 cases) treated by RFCA， and sotalol 160 mg was orally administered and intracar diac electrophysiological study was performed every 30 min for 5 times. Th e other group(control group, 18 cases) only treated by RFCA.QTd,QTcd and QTLcd w ere measured before and after RFCA. Results: There was no signif icant difference with QT dispersion before and after RFCA in control group. When compared with before RFCA, QTd in patients administered sotalol was (30.9 ±14.3) ms vs (24.7±9.6) ms; QTcd(33.7±17.1) ms vs (25.2±10.1) ms; QT Lcd(30.8±14.1)ms vs (25.6±19.4) ms (P<0.05). Conclusion: Sotalol can slightly lower QT dispersion, which is beneficial for preventing malignant ventricular arrthythmia. It is safe in RFCA in pateints with accessory pathway.

For the high cost and mobility issues, a home uterine contraction pressure monitoring system based on Windows CE platform was developed. In this paper, the design of hardware circuit, micro-controller system and LabVIEW program based on Windows CE are discussed. The clinical validation experiment in hospital for this system was made and the experimental results show that this system complies with the trend that current medical equipment is becoming portable, homely and networked. Through real-time monitoring uterine contraction pressure, occurrence of premature birth and abortion can be prevented effectively.

Seat lumbar rotation technique is a commonly used technique,and the clinician is also a kind of clinical curative effect more apparent bone-setting reduction technique.However,the power of spinning technique,direction and position selection is based on the personal experience of the clinician,the lack of a unified,standardized scientific basis for support.Now the article reviews the studies of the rotation of the seat,including lumbar anatomy,biomechanical characteristics,clicks,mechanism of action,and safety.It will provide new ideas for standardizing operations research techniques.

Objective: To observe the influence of sotalol on the QT dispersion in patients with atrioventricular accessory pathways underwent radiofrequency catheter ablation (RFCA). Methods: Thirty six patients were divided into 2 groups by random. One was the drug group(18 cases) treated by RFCA, and sotalol 160 mg was orally administered and intracardiac electrophysiological study was performed every 30 min for 5 times. The other group(control group, 18 cases) only treated by RFCA.QTd,QTcd and QTLcd were measured before and after RFCA. Results: There was no significant difference with QT dispersion before and after RFCA in control group. When compared with before RFCA, QTd in patients administered sotalol was (30.9?14.3) ms vs (24.7?9.6) ms; QTcd(33.7?17.1) ms vs (25.2?10.1) ms; QTLcd(30.8?14.1)ms vs (25.6?19.4) ms ( P

Objective: To investigate the effects of pravastatin o n atherosclerotic plaque and cardiovascular events. Methods: Fifty- seven patients with coronary artery disease (44 male and 13 female, 58.4±11.3 y ears) were randommized into pravastatin and control groups. The patients in prav astatin group were administered 10 mg of pravastatin from the night of coronary angiography day. After 7.3 months (mean) of follow-up, plasma lipid parameters and coronary angiograph were repeated. Results: (1) A favorable effect on plasma lipid parameters was found. After administration, total choles terol(TC), low density lipoprotein cholesterol (LDL-C) and triglyceride(TG) red uced by 15.0% (P<0.01), 18.0% (P<0.01) and 6.0%, respectively. High den s ity lipoprotein cholesterol(HDL-C) increased by 10.6%. However, in control grou p, TC and LDL-C showed a tendency to reduce, but no significant difference was found between those of pre- and post-administration. (2)There was no significa nt difference in luminal diameter between pre- and post-administration in both groups. (3) Cardiovascular events in pravastatin group was significantly lower than those in control (P<0.05). (4) Pravastatin had no significant effect on HR, BP and left ventricular ejection fraction in both groups. Conclusio n: Pravastatin can stabilize coronary atherosclerostic plaque and reduce the incidence of cardiovascular events by improving plasma lipid parameters.

Objective To study the influence of mediating/moderating effects of health skills on the relations between health knowledge and health behaviors in college students.Methods Stratified cluster random sampling was used among 2 181 students,selected in several colleges in Changsha,Hunan province.EpiData 3.0 was adopted to establish the database.Correlation and regression analyses were performed by SPSS 17.0.Results Positive correlations were seen on:1)Knowledge and skills on health (r=0.592,P＜0.01),2)Knowledge and behaviors on health (r=0.647,P＜0.01),3)Health skills and health behaviors (r=0.629,P＜0.01).The mediating effect of health skills on the relations between health knowledge and health behaviors was significant (34.55％).The interaction effect of "health skill × (times) related knowledge" was significant (β =-0.093,t =-5.212,P=0.000).New variables that were produced by the interaction also reached significant level (△R2=0.006,P=0.000),resulted in increasing the explanation function to health behaviors by 0.6％.Conclusion Health skills could partially mediate the effects and moderate the relationship between health knowledge and health behaviors among college students.
