Intervention effect of health education on the knowledge and awareness of hypertension in primary and secondary school students / 中华全科医师杂志

Objective:To explore the effects of health education on the knowledge and awareness of hypertension in primary and secondary school students.Methods:Twenty seven primary and secondary schools in Emin County of Xinjiang Uygur Autonomous Region were selected in 2014 as study sites; among which 24 schools were randomly assigned as the intervention group and 3 schools were assigned as control group. According to the education methods (classroom teaching, publicity manual, hypertension class reports and the combination of the three) and the frequency of education (1, 2, 3 times per semester), the intervention group were further randomly divided into 12 subgroups with 2 schools in each group. The intervention study was carried out for 3 years.Results:A total 13 402 students were involved in the study, and there were 11 333 students in the intervention group and 2 069 students in the control group. The awareness rates of hypertension concept [41.8% (4 738/11 333) vs. 24.6% (511/2 069), χ 2=154.86, P<0.01], the adverse consequences of hypertension [85.8% (9 735/11 333) vs. 75.4% (1 561/2 069),χ 2=25.80, P<0.01], the hypertension risk factors [84.3% (9 564/11 333) vs. 72.5%(1 501/2 069), χ 2=12.83, P<0.01), and the health behaviors after hypertension [84.9% (9 629/11 333) vs. 67.7%(1 402/2 069), χ 2=187.24, P<0.01] in intervention group were all significantly higher than those in control group. The stratified analysis showed that among students in elementary school, junior high school and high school, there were significant differences in the awareness rate of adverse consequences [94.4% (2 019/2 138) vs. 81.6% (3 829/4 690), 86.2% (3 887/4 505), χ 2=199.31, P<0.01], awareness rate of risk factor [86.8% (1 857/2 138) vs.86.1% (4 038/4 690), 81.4% (3 669/4 505) , χ 2=49.96, P<0.01); and awareness rate of correct behavior [89.9% (1 923/2 138) vs. 86.1% (4 037/4 690), 81.4% (3 669/4 505) χ 2=89.77, P<0.01]. Up to 95.9% (10 868/11 333) students in the intervention group liked the hypertension health education. Conclusion:Based on the school health education curriculum, the intervention measures of hypertension health education are effective, and the awareness rate of hypertension related knowledge among senior high school students is significantly improved.

Clinical effect of anchorage of saphenous nerve on repairing medial collateral ligament injury of knee joint / 中国医师进修杂志

Objective To evaluate the clinical effect of protecting the saphenous nerve with the suture anchor on repairing the medial collateral ligament injury of the knee joint. Methods From June 2014 to June 2016, 48 cases of medial collateral ligament injuries of the knee joint were repaired with suture anchors of the saphenous nerve in the 107th Hospital of PLA. Results All patients were followed up for 12-18 months, with an average of 14.6 months. All the patients were followed up with good stability of the knee joint. The 30 degree flexion stress test of the knee joint showed that 2 cases were positive forⅠdegree, and the stress test of the extension position was negative. The X-ray examination showed that the internal and external articular space of the knee joint was symmetrical and good, and the anchors did not loose or move in the bone. The average knee flexion before operation was (43.19 ± 2.60)°, and 1 year after operation was (135.62 ± 3.68) °. And the flexion of knee 1 year after operation was higher than that before operation (t=5.37, P<0.01). The Lysholm score was (43.19 ± 2.60) points before operation, and 1 year after operation was (93.69 ± 5.39) points, and the postoperative score was higher than that before operation (t=4.85, P<0.01). The grade of efficacy was excellent in 42 cases, good in 4 cases, fair in 2 cases, and the excellent and good rate was 95.8％(46/48). Conclusions The repair of medial collateral ligament injury with suture anchors under the protection of the hidden nerve can effectively prevent the symptoms of numbness in the medial area of the knee joint. It is simple, fixed and can be repaired under direct vision. It is reliable to restore the strength of the ligament and maintain the stability of the medial knee joint. It is worthy of clinical push and wide application.

Expression features of osteoprotegerin, receptor activator of nuclear factor kappa-B and receptor activator of nuclear factor kappa-B ligand in avascular necrosis femoral head / 中国生化药物杂志

Objective To determine the protective effect of osteoprotegerin (OPG), receptor activator of nuclear factor kappa-B (RANK) and RANK ligand (RANKL) on avascular necrosis femoral head.Methods Necrotic tissue or corresponding normal tissues were collected from 29 avascular necrosis femoral head patients.Quantitative Real TimePCR ( qPCR ) is used to evaluate mRNA expression of OPG , RANK and RANKL.OPG and RANKL protein levels were estimated by Western blot.Results The results of qPCR showed that the expression of OPG in the necrotic tissue was significantly higher than that in the normal tissue (4.56 ±0.37) (3.39 ±0.52) (P<0.05).The expression levels of RANKL mRNA in necrotic tissues and normal tissues were (0.86 ±0.11) and (0.31 ±0.08), respectively,the difference was statistically significant (P<0.05).The expression levels of RANK mRNA in necrotic tissues and normal tissmes were(0.87 ±0.12), (0.56 ±0.13) respectively,the difference was statistically significant (P<0.05).The ratio of RANKL/OPG and RANK/OPG in normal tissues were 0.69 and 0.52, respectively.In the necrotic tissues, RANKL/OPG and RANK/OPG ratios were 1.35 and 0.61, respectively.Results of Western blot showed that the expression of OPG in necrotic tissues was consistent with that in normal tissues.The expression of RANKL protein was detected in all samples , and the expression of RANKL protein in necrotic tissue and normal tissue was almost the same.RANK protein expression was not detected in all samples.Conclusion OPG, RANK and RANKL play important roles in progress of bone remodeling in necrotic area and in disturbance of bone homeostasis and might have an effect on bone destruction and subsequent collapse of hip joint.
