Objective To investigate the efficacy of 50% acetic acid as a renal cyst sclerotherapy agent, and with further comparison to that of absolute alcohol. Methods Eighty five patients with renal cyst were undergone sclerotherapy through spiral CT guidance including 43 cases with absolute alcohol and the others with 50% acetic acid as sclerosing agents. All the cysts were aspirated under CT-guidance, beforehand. The sclerosising agents were withdrawn from the cysts after a definite period of retention. Results The disappearance rates of cyst cavity with absolute alcohol and acetic acid were 55.81% and 71.42%, respectively. Complication occurence rates with absolute alcohol and acetic acid were 16.28% and 4.76% , respectively. The average retention periods of absolute alcohol and acetic acid in cyst were (20?4)minutes, and (10?2)minutes, respectively. Statistical analysis demonstrated that all the data in two groups were significantly different. Conclusion Using 50% acetic acid as sclerosising agent in treating renal cyst possesses the better effect and less side effect, providing a tendency to replace the traditional therapy.

Objective To observe the clinical efficacy of fire-needle therapy in treating scapulohumeral periarthritis, and to observe the changes of pain score and the motor function of shoulder joint. Method Totally 180 patients were randomized into a fire-needle therapy group of 90 cases and a filiform needle group of 90 cases by randomized single-blinded method. Result There were significant differences between the two groups in comparing the recovery rate, motor function of shoulder joint, and the relapse rate 30 d after the whole intervention (P<0.01), while there were no significant differences in Visual Analogue Scale (VAS) score and total effective rate (P>0.05). Conclusion Compared to filiform needle therapy, fire-needle therapy can produce a better recovery rate and motor function of shoulder joint in treating scapulohumeral periarthritis.
