Objective To investigate the effect of fluoride on expression of Runx2 mRNA and protein in bone tissue of rats. Methods Fourteen SD rats were randomly divided into two groups: control group(tap water with fluoride ＜ 0.06 mg/L), and fluorosis group(fluoride 50 mg/L in water). After 4 moths, expressions of both mRNA and protein of Runx2 in rat bone tissue were determined by RT-PCR and Western blotting. Results The results showed that the expression of Runx2 mRNA and protein in fluoride-treated bone tissue were 2.287 ± 0.261 and 0.929 ± 0.229, respectively, both of which were significantly higher than those of control group(0.995 ± 0.123,0.317 ± 0.068, t = 11.85,6.78, P ＜ 0.05). Conclusions Fluoride can increase the expression of Runx2 mRNA and protein in bone tissue of rats, and Runx2 may be involved in the pathogenesis of bone injury caused by fluoride.

Objective To assess the practical value of ultrasound-guided percutaneous pericardium centesis in patients with pericardial effusion.Methods Twenty-eight patients with pericardial effusion were treated with ultrasound-guided percutaneous pericardium centesis from May 2004 to May 2009.Results Operations were successfully done in all 28 patients.The puncture needle,guide wire and drainage catheter could be clearly visualized under ultrasound.Complications included ache,bleeding and drainage catheter obstruction or prolapsus.Conclusion Able to be used bedside,ultrasoundguided percutaneous pericardium centesis is a real time,exact,safe and convenient method for the diagnosis and treatment of pericardial effusion.

By summarizing the recent literatures on brain mechanisms with acupuncture intervention based on blood oxygenation level-dependent (BOLD)-functional magnetic resonance imaging (fMRI), the BOLD-fMRI examination and analysis methods, the points to be acupunctured, the corresponding meridian activation regions, the specific intensity range, functions and indications of the acupoints, the manifestation of 'bi-directional regulation' characteristics, fMRI performance of chronergy, laterality and needling qi of acupuncture were reviewed to provide the ideas for future research in this area.

ObjectiveTo observe the effect of language rehabilitation training on stroke patients with complete aphasia.Methods10 stroke patients with complete aphasia were treated with language rehabilitation training.ResultsAfter training, scores of hearing, naming, reciting, reading, and writing of patients were significant higher than that before training (P<0.05—0.01).Conclusion Language rehabilitation training plays an active role in rehabilitation of stroke patients with complete aphasia.

OBJECTIVETo observe application value of multispectral animal living imaging technology in rats model of osteoarthritis.

METHODSFifteen male SD rats weighed (180 +/- 20) g (3 months old) were received intra-articular injection of iodoacetic acid for establishing osteoarthritis. Articular cavity of left knee of rats were injected into 50 microl iodoacetic acid. The same volume of sterile saline was injected into right knee articular cavity as control. X-ray living imaging and bone mineral density were observed at 2 and 4 weeks after establishment of model. After 4 weeks,rats were sacrificed and their bilateral joints were collected and determined histologically based on Collins classification and Kellgren-Lawrence classification.

RESULTSOsteoarthritis model was successfully established, compared with control group, model group showed typical manifestation of osteoarthritis, including irregular cartilage surface,osteophyte formation,joint deformity and cartilage defect,and combined with significant decrease of bone density (P < 0.01), while the decrease was not obvious in proximal tibia (P < 0.05). After 2 weeks, knee joints in model group was classified as Collins grade 1 and Kellgren-Lawrence grade 2,then classified as Collins grade 4 and Kellgren-Lawrence grade 3 after 4 weeks,control group showed smooth articular surface,normal joint space and intact cartilage surface, knee joints was classified as Collins and Kellgren-Lawrence grade 0, and bone density of distal femur and proximal tibia were normal.

CONCLUSIONMultispectral animal living imaging technology could be used in dynamic observation of living imaging and detection of bone density in the animal model of osteoarthritis, and it is significant for evaluation of osteoarthritis model, and its realted tesearch.

OBJECTIVETo analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification.

METHODSThis was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011. All the patients were divided into two groups: no combination with fracture of processus styloideus ulnae (group A, 56 cases), combination with fracture of processus styloideus ulnae (group B, 20 cases). The patients in group A and B were treated with open reduction and internal fixation; however the fracture of processus styloideus ulnae was not fixed. The indexes such as clinical data, bone grafting, joint movement, Gartland & Werley score and radiographic score were compared between two groups.

RESULTSThe ulnaris pain of patients in group B was more obvious than that in group A. The local VAS, palmar and dorsal flexion degree of wrist joint, motion VAS, patients satisfaction score, radial and ulnar deviation degree, pronation and supination of forearm degree, Gartland & Werley score and radiographic score were separately 0.1 ± 0.1, (51.1 ± 1.9)°, (60.2 ± 1.9)°, 0.6 ± 0.1 (23.1 ± 0.9)°, (28.7 ± 1.3)° (81.5 ± 2.6)°, (68.2 ± 2.7)° 1.9 ± 0.3, 89.6 ± 12.3 in group A; and separately 0.3 ± 0.3, (51.4 ± 2.3)°, (66.6 ± 1.7)°, 0.5 ± 0.2, (24.5 ± 2.0)°, (26.9 ± 1.8)°, (80.3 ± 2.5)°, (70.3 ± 3.7)°, 1.2 ± 0.4, 92.5 ± 7.5 in group B; there were no statistical differences in above indexes between two groups.

CONCLUSIONWhether the distal radial fracture with a concomitant unrepaired ulnar styloid fracture or not exerts no influence on mainly outcomes including function, radiography and motion of the wrist.

The market and literature were studied to understand the existing situation of Magnoliae Officinalis Cortex goods, and the collected samples were analyzed, combined with the actual production, a new standard of Magnoliae Officinalis Cortex commercial specification and grade was drafted. Magnoliae Officinalis Cortex goods was divided into two categories according to the source in the old standard. Then each category was divided into four kinds of specifications according to the site. Each kind of specification was divided into several grades according to the length and weight. To judge the quality of Magnoliae Officinalis Cortex goods was mainly based on the appearance quality. In the new standard, the classification of commercial specification and grade is based on the thickness, magnolol and honokiol content. The goods of Magnoliae Officinalis Cortex can be divided into three specifications: Tongpu, Genpu and Doupu. Tongpu is divided into three grades, the remaining two are not graded.
