OBJECTIVE@#To compare 3 commonly used methods for drug delivery via the lumbar spinal subarachnoid space in rats.@*METHODS@#We compared the effects of 3 methods for drug delivery via the lumbar spinal subarachnoid space in Sprague Dawley rats, namely acute needle puncture, chronic catheterization via laminectomy, and non-laminectomized catheterization. Body weight changes of the rats were measured, and their general and neurological conditions were assessed after the surgeries. The motor function of the rats was examined using rota rod test both before and after the surgeries. Nociceptive tests were performed to assess nociception of the rats. HE staining was used to examine local inflammation caused by the surgeries in the lumbar spinal cord tissue, and lidocaine paralysis detection and toluidine blue dye assay were used to confirm the precision of drug delivery using the 3 methods.@*RESULTS@#Both needle puncture and catheterization via laminectomy resulted in a relatively low success rate of surgery and caused neurological abnormalities, severe motor dysfunction, hyperalgesia, allodynia and local inflammation. Catheterization without laminectomy had the highest success rate of surgery, and induced only mild agitation, slight cerebral spinal fluid leakage, mild sensory and motor abnormalities, and minimum pathology in the lumbar spinal cord. Catheterization without laminectomy produced less detectable effects on the behaviors in the rats and was well tolerated compared to the other two methods with also higher precision of drug delivery.@*CONCLUSIONS@#Catheterization without laminectomy is a safe, accurate and effective approach to lumbar drug delivery in rats.

Objective To explore the imaging radiological and clinicopathological characteristics of benign fibrous histiocytoma (BFH) of bone, in order to improve the imaging diagnostic accuracy of the disease Methods Radiological and clinical data of 16 patients with BFH confirmedbypathology were retrospectively analyzed , and relevant literatures were reviewed. Results The X-ray findings of 14 BFHpatients were osteolytic lesion , expansive destruction of bone,without soft tissue involvement, 10 with residual apophysis,9 with osteosclerosis marginal; CT was performed on 2 patients. Expansive destruction of bone and soft tissue densities were seen inside the loops , 1 case remarkable enhancement of the lesion. MRI was performed on 9 patients and 5 cases showed long T1 and T2 signal intensity; 1case showed equal T1 and long T2 signal intensity in cystic part and equal T1 and T2 signal intensity in the solid part. One patient had pathological fracture, and the surrounding soft tissue invaded, showing equal T1 and long T2 signal intensity. Two lesions located at spinous process of cervical vertebra , showing long T1 short T2 and equal T1 and T2 signal intensity. Linear low signal separation shadow in T1 and T2 could be seen in 6 cases. Long T1 and short T2 sclerotic ring were seen in 4 cases. Solid part of tumor and linear separator were obviously enhanced. Conclusions The radiological findings of benign fibrous histioeytoma of bone indicate some characteristics. The combination with X-ray , CT and MRI examination is helpful to improve the diagnostic accuracy of the disease before operation.

<p><b>OBJECTIVE</b>To investigate the effects of obstructive sleep apnea-hypopnea syndrome (OSAHS) and age on sleep architecture and the therapeutic effects of continuous positive airway pressure (CPAP).</p><p><b>METHODS</b>We retrospectively analyzed 222 subjects undergoing polysomnography (PSG) for snoring, who received CPAP under PSG on the next day following the initial PSG. The sleep architecture of the subjects in different age groups and in groups with different severities of OSAHS was analyzed before and after adjustment for apnea-hypopnea index (AHI) or age. The sleep architecture and ventilation function of the patients with OSAHS were also analyzed after CPAP.</p><p><b>RESULTS</b>N3 sleep showed the strongest correlation with AHI (r=-0.361), and REM sleep and wake after sleep onset (WASO) were the most strongly correlated with age (r=-0.211 and 0.216, respectively). The 4 age groups showed significant differences in sleep efficiency (P<0.001), N1 (P=0.015), N2 (P=0.013) and REM (P=0.030) sleeps, and WASO (P=0.001) but not in AHI (P=0.185). REM sleep decreased and WASO increased with an increasing age. The sleep efficiency and architecture were still significant different after adjustment for AHI. In 4 groups with different severity of OSAHS, N1, N2 and N3 sleeps were significant different after adjustment for age (P=0.011, 0.017, 0.001). In patients with moderate or severe OSAHS, N3 sleep increased with the increase of AHI. After CPAP for OSAHS, N1 and N2 sleeps significantly decreased, and N3 and REM sleeps increased (P<0.001).</p><p><b>CONCLUSION</b>Between OSAHS and age, REM sleep and WTSO are more importantly affected by age, while OSAHS more strongly affects N3 sleep. CPAP can improve the sleep quality of patients with OSAHS.</p>

This paper analyzed the current situation of health examination and reflected on the ways of carrying out health education in the process of health examination. The paper analyzed five problems of carrying out health education in the process of health examination and put forward the countermeasures for every problem in order to arouse people's attention to health examination and im-prove their understanding of health education.
