Objective To evaluate the early diagnosis value of MRI combined with DSA in cirrhotic nodules (regenerative nodules, dysplastic nodules) becoming small hepatocellular carcinoma. Methods 40 patients diagnosed as cirrhosis and whose liver nodules detected by ultrasound were followed up as MR dynamic study. All patients were followed up by three dynamic contrast-enhanced MR scanning once every 3 months,and the changes of cirrhotic nodules were observed and analyzed in the signal. If MRI suggested cancerous nodules cirrhosis, hepatic artery DSA would be carried out. Results 40 patients were followed up for 1.5 to 3 years,all patients MR nodules were found in liver regeneration. Follow-up process, the dysplastic nodules were founded in 28 cases and the small hepatocellular carcinoma were founded in 18 patients. 16 cases of 18 patients with small hepatocellular carcinoma carried out routine DSA all had typical of hepatic arterial blood supply and angiogenesis, and were given to Integrated Traditional and Western intervention simultaneously. Conclusion Combined use of MRI-DSA in the evaluation of cirrhotic nodules had a definite value, and could find smaller hepatocellular carcinoma,provide the basis for smaller hepatocellular carcinoma therapy.

The hidden risk of acupuncture has become the factor of the high incidence of adverse reaction of acupuncture in clinical practice. The retrospective analysis and the typical cases analysis are especially important for the prevention from the hidden risk of acupuncture. In the paper, the relevant literatures were reviewed, the basic diseases were listed such as diabetes, hypertension and digestive gastric ulcer that were neglected by the physicians, and the adverse reactions induced by the therapeutic history and the body constitutions were analyzed. It was stated in the paper that because of the individual factors of patient, the risks of the atypical clinical accidents of acupuncture were extremely serious and easily neglected by the clinical acupuncture physicians. It is very necessary to remind the clinical acupuncture physicians to understand the basic diseases, basic treatment as well as the peculiarity of body constitution of the patients besides their chief complaints. Moreover, acupuncture should be applied very carefully after identifying the pulse condition and the contraindication so as to ensure the patient's safety and obtain the optimal efficacy.
