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.

Objective To evaluate the clinical result of long stem bipolar femur prosthetic replacement for elderly patients with intertrochanteric fractures.Methods A total 48 patients of intertrochanteric fractures,at age of 70 years or above,were treated with cemented long stem bipolar femur prosthetics.The surgery time,blood loss,Harris hip score and complication rate were observed.Results The average surgery time,the blood loss,Harris hip scores of the arthroplasty were 70 minutes,400 ml and 87 ml,respectively,without any complications.Conclusion Long stem bipolar femur prosthetic replacement can gain good hip function and decrease the complications of fracture in treating intertrochanteric fractures.

Purpose To investigate the association between the macular volume and thickness,as assessed by optical coherence tomography(OCT),with refraction state and axial length(AL)in children.Methods A total of 100 normal children whose right eyes were randomly selected were divided into five groups due to their refraction,comprising hyperopia,emmetropia,low myopia,moderate myopia,high myopia.The AL of the eyes was measured by IOL master measuring machine.Then the macular volume and thickness were measured bv OCT.Results Children with high myopia have smaller macular volume and thinner parafoveal retinal thickness(especially out-ring macular).The minimum thickness and average thickness of the fovea were not significantly different among the five groups.The macular volume ,total average macular thickness and quadrant-specific macular thickness(except the nasal inner quadrants)were positively associated with refraction and negatively associated with AL,while there were no correlation between minimum foveal thickness,the average foveal thickness and refraction or AL.Conclusions In Chinese children,increasing axial length was associated with reduced maeular volume and thickness(except the foveal region and the nasal inner quadrant).

To prepare salvianolic acid phospholipid compound. With the compound of salvianolic acids and soybean phospholipid as the index, mono-factor experiment and orthogonal design experiment were conducted to screen its technical parameters. According to the results, the optimal preparation conditions of salvianolic acid phospholipid compound were that THF were taken as the reaction solvent, the concentration time was 3 h, the reactant concentration was 5 g x L(-1), the mass ratio of salvianolic acids and phospholipid was 1: 1.5, and the reaction temperature was 40 degrees C. The oil/water partition coefficient of the prepared salvianolic acid phospholipid compound significant increased in water and buffers with different pH values. The results of phase analysis such as DSC, XRD and FTIR indicated that salvianolic acids existed in phospholipid in an amorphous state.

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.

AIM: To retrospectively evaluate the effect of lens extraction combined with vitrectomy to treat traumatic lens dislocation with secondary glaucoma.
METHODS: Thirty - one eyes ( 31 cases ) of lens dislocation caused by blunt trauma with secondary glaucoma were treated respectively with cataract extraction combined with anterior vitrectomy, trabeculectomy and intraocular lens implantation. The visual acuity and pressure were observed 1wk, 1 and 3mo after operative.
RESULTS: Thirty - one eyes were all complete the operation successfully, and 6 eyes were given combined trabeculectomy, 9 eyes were implanted anterior chamber intraocular lens implantation ( IOL ) and 15 eyes were given posterior chamber suture fixation. Sixteen eyes were implanted in one-stage operation, while 8 eyes were implanted in two-stage operation. All intraocular pressure ( IOP ) were controlled to the normal level after operation and 23 eyes had visual acuity of more than 0. 3. CONCLUSION: Lens extraction combined with vitrectomy is an effective method for treatment of lens dislocation with secondary glaucoma. In order to control the IOP and get well visual function, we should choose IOL implantation or trabeculectomy according to the patient's condition.
