As traditional Chinese medicine components have become a hotspot in the field of traditional Chinese medicine study, they have followed a development trend of diversity and false identification. In studies on a new modem product, we shall encourage the diversified development mode, but avoid the false concept identification of traditional Chinese medicine components. In this paper, by analyzing the current development of traditional Chinese medicine components and problems, we discussed the standardization of traditional Chinese medicine components, with the aim of reducing and avoiding the situations to study non-traditional Chinese medicine components as traditional Chinese medicine components.

Objective To find out demography characteristic and risk behaviors of occupation groups and to evaluate the effect of health education. Methods A baseline survey was conducted among occupation groups in the western part of Liaoning province by stratified random cluster sampling. Health education started to intervene in occupation groups in Linghai city of Liaoning province. An investigation of brucellosis related behaviors was carried out before and after a health education among occupation groups. Other occupational groups were as the control group. The research on high-risk behaviors of occupation groups was in the following eight aspects: protection taken when contact with abortion livestock, timely slaughter and burying deeply of sick animals, not selling sick animals do not eat dead meat, nor drink raw milk, do not eat raw meat, and immunity of livestock. Results Before the intervention, a total of 916 objects, of which intervention group 499 and control group 417 were investigated. The high-risk behaviors of brucellosis were not significantly different between the two groups[70.9% (354/499), 64.3%(321/499 ), 53.8% (268/499), 92.2% (460/499), 82.2% (410/499 ), 87.5% (437/499), 93.6% (467/499), 56.2%(280/499) in intervention group, 68.8% (287/417), 59.2% (247/417 ), 54.7% (228/417), 89.2% (372/417 ), 85.6%(360/417) ,885%(369/417),94.0%(392/417),55.9%(233/417) in control group, all P ＞ 0.05]. After the intervention,a total of 908 survey objects, of which intervention group 499 and control group 409, were investigated. The above eight aspects of high-risk behaviors in the intervention group were 85.4% (426/499),79.0% (394/499),69.9%(349/499),96.4%(481/499),943%(471/499),94.9%(474/499),94.0%(469/499), 99.4%(496/499), respectively; in the control 66.8% (273/409),57.3% (234/409),50.1% (205/409),85.3% (349/409),88.8% (363/409),89.5%(366/409) ,90.1% (369/409), and 57.2% (234/409), respectively. Between the two groups, the difference was statistically significant (x2 = 43.991,49.833,37.111,35.032,9.537,9.826,4.485,253.808, all P ＜ 0.05 ). The above seven aspects of high-risk behaviors except do not eat raw dairy at the beginning of intervention were compared with those of after the intervention, the differences were statistically significant (x2 = 30.426,26.284,27.854,7.364,36.027,17.238,9270.286, all P ＜ 0.05). Conclusions Health education intervention can significantly improve the behavior change rate of occupational groups at high risk of brucellosis, and the education intervention is worthwhile to communicate and promote.

BACKGROUND:Fragile bone in senile osteoporosis patients easily weakened pedicle screw fixation capacity. Therefore, bone cement leakage and screw removal cannot be solved during pedicle screw repair in osteoporotic patients with degenerative lumbar spine. OBJECTIVE:To investigate the biomechanical properties of novel pourable pedicle screws and bone cement application effect in osteoporotic patients with degenerative lumbar spine. METHODS:Six lumbar specimens (T11-L5) at the mean age of (72.9±4.2) years were selected, total y 42 vertebrae. The average bone density was 0.696 g/cm2. Any side of al vertebrae was inserted with pourable pedicle screws. 2 mL of bone cement was perfused under the X-ray fluoroscopy with cement push rod and fil ing cylinder. The same number of conventional screws was inserted into the opposite side of the samples. Three-point bending test was performed in two kinds of screws. The maximum vertebral axial pul out force test and the maximum spin torque test were conducted in vertebra to observe the destruction of the vertebral body and implanted effect. RESULTS AND CONCLUSION:(1) The ultimate strength and yield load of novel pourable cement pedicle screws were significantly more than conventional screws (P<0.05). Ultimate displacement and yield displacement were significantly less in novel pourable cement pedicle screws than in conventional screws (P<0.05). (2) The maximum vertebral axial pul out force and the maximum spin torque were significantly higher in novel pourable pedicle screws than in conventional screws (P<0.05). (3) In summary, novel pourable cement pedicle screw is simple to operate, can effectively control bone cement penetration, and improve screw stability in osteoporotic vertebrae. Moreover, after treatment, the removal of screws is convenient, cannot evidently destroy vertebral body or screw channel, and promote early recovery.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.
