In the article, it thinks that moral lacking of advertisement is the basic reason which leads to intensified illegal medical advertisement. The main reasons for moral lacking of advertisement: imperfect legal system of medical advertisement, indifferent ethical consciousness of medical advertisement, insufficient social supervision of medical advertisement. Therefore, we should perfect the legislation, establish the correct advertising moral concept, improve the quality of advertising employees, and realize the function of social supervision fully.

Objective To assess the diagnostic value of susceptibility weighted imaging in intracranial capillary telangiectasia. Methods Clinical and imaging data of 1 3 cases with pathologically proved intracranial telangiectasia were collected.All 1 3 patients were examined with conventional MRI and SWI scanning,five patients were checked with MRA while other six cases were examined by CT scanner,and the results were compared.Results All 13 patients had multiple lesions and a total of 176 lesions were detected by SWI,exhibiting hypointense with possiblely punctate hyperintense in the center .Fifty-two lesions were detected by T1 weighted imaging;105 lesions were detected by T2 weighted imaging;112 lesions were detected by fluid attenuated inversion recovery;69 lesions were detected by diffusion weighted imaging;6 9 lesions were detected by apparent diffusion coefficient.Six cases underwent CT scanning, and one showed multiple low density while the remaining five cases did not find any abnormalities.No cerebral vascular malformation was found in five cases scanned by MRA.The lesions showed round or oval shape,ranging from 3 mm to 17mm in diameter.Among them,98 lesions were located in the pons,39 in cerebellum,23 in cortex,10 in basal ganglia,6 in thalamus.Conclusion SWI is the sensitive sequence to detect intracranial capillary telangiectasia.SWI could be used as the preferred imaging method for intracranial capillary telangiectasia.

Objective To observe the pain behavior of rats with Oxaliplatin‐induced peripheral neuropathy(OXIPN)and cal‐citonin gene related peptide(CGRP)expression.Methods Twenty Wistar rats were randomly divided into 2 groups :normal con‐trol group and model group.Oxaliplatin(20 mg/kg)was injected intraperitoneally to the rats in the model group.Mechanical pain threshold and cold allodynia were detected before and 6 ,24 ,72 h and 7 days after modeling ,respectively.Western blot and im‐munohistochemical method were employed to measure the expression of CGRP in dorsal spinal root ganglion of control group and model group.Results The mechanical pain threshold of modal group rats decreased 6 h after injection of Oxaliplatin as compared with the normal group[(11.6 ± 2.2)g vs. (13.9 ± 3.7)g] ,and decreased with prolongation of time ,reduced to the lowest at 72 h[(3.9 ± 1.4)g]and maintained to day 7 ,and the same trend was found in cold chemical allodynia test.CGRP ex‐pression of dorsal root ganglion increased significantly in the model group rats ,and there was a significant positive correlation between the expression of CGRP and the degree of mechanical pain threshold.Conclusion CGRP plays an important role in Ox‐aliplatin‐induced central sensitization of rats with peripheral neuropathy.
