Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.

OBJECTIVE To prevent nosocomial infection and increase the safety of blood supply so as to evaluate the feasibility of routine detections in screening blood donations for HBV DNA and HBV markers. METHODS(Three hundred blood) donors and 346 cases were detected by ELISA for HBV markers,and then performed by LightCycler for HBV DNA. RESULTS One(1.6%) of 62 negative samples of HBV markers in 346 cases was positive for HBV DNA.Out of 300 qualified donors in screening tests,six(2%) were positive for HBV DNA.And two(0.9%) of 222 negative samples of HBV markers were positive for HBV DNA. CONCLUSIONS This study shows that there are HBV infections with negative hepatitis B surface antigen(HBsAg) in population of Qingdao area and that incorporating fluorescence quantitative PCR into ELISA in screening blood donations for HBV infection will further increase the safety of blood supply and prevent nosocomial infections.

Objective To evaluate the effectiveness of comprehensive lifestyle modification in the primary health care system on status of pre-chronic diseases in a conventional healthcare program.Methods Two hundred and twenty-nine adult volunteers in 5 conventional healthcare centers were divided into 4 groups:group of prehypertension(n=67),group of prediabetes(n=38),group of abnormity serum cholesterol(n=71)and group of osteopenia(n=53).A muhicomponent behavioral intervention including education,physical activity,dietary practice,cease smoke,calcium supplement and exposure to sunlight was conducted for 12 months.The main outcome of each group was blood pressure,blood glucose,serum cholesterol and bone mineral density.Results Over 12 months,compared with the status before intervention,participants in each group were statistically significantly improved,the mean net reduction in systolic BP/diastolic BP was 9.4 mm Hg/6.6 mm Hg(1 mm Hg=0.133 kPa,t=5.93/8.29.P＜0.05)in group of prehypertension;the reductions of blood glucose,serum cholesterol were 0.9 mmol/L(t=3.69,P＜0.05)and 0.5 mmol/L(t=4.09,P＜0.05)in group of prediabetes and group of abnormity serum cholesterol,and the increase of bone mineral density on lumbar spine was 0.015 g/cm2(t=2.03,P＜0.05)in group of osteopenia,Conclusions For chronic disease prevention,ater one year the comprehensive lifestyle intervention produced beneficial changes in diet,physical activity,and biochemical parameters.This type of intervention is a feasible option to prevent chronic disease and should be implemented in the primary health care system.

ObjectiveTo investigate the relationship of lower extremity muscle strength and the pain or physical function in patients with knee osteoarthritis. Methods25 patients with knee osteoarthritis diagnosed with have radiological and clinical data were assessed with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and isokinetic muscle strength testing. ResultsThe lower extremity extensor muscle strength correlated with WOMAC pain scores, WOMAC activity of daily life scores, and WOMAC total scores （P<0.05）. ConclusionThe lower extremity extensor muscle strength correlated with the pain and physical function in patients with knee osteoarthritis.

Objective To explore the relationship between the somatosensory evoked potential (SEP) diversification during operation and the short term outcome of ossification of posterior longitudinal ligament (OPLL) of cervical spine. Methods 70 OPLL inpatients from February 2008 to February 2011were included in this study. All patients received anterior cervical operation. According to the diversification of the SEP during surgery, the patients were divided into 2 groups. The preoperative and postoperative JOA scores of the OPLL patients were collected. Results There were 35 patients in the SEP no change group and 30 in SEP improved group. There was no difference in the preoperative JOA scores between them (P>0.05), but was significantly different in the postoperative JOA scores (P>0.05). Conclusion There is some relationship between the SEP diversification during operation and the short term outcome of OPLL of cervical spine.
