OBJECTIVE To compare the effect and safety of coblation plasma surgery and beclomethasone dipropionate nasal spray in the treatment of perennial allergic rhinitis. METHODS A stratified,randomized,controlled trial of surgery and medicament was performed in the treatment of perennial allergic rhinitis. A total number of 102 patients were involved in the trial,including 56 cases with swelling of inferior turbinate,28 cases in surgery group,28 cases in medicament group; and 46 cases without swelling of inferior turbinate,23 cases in surgery group,23 cases in medicament group. Coblation plasma surgery was performed in all surgery groups. Each patient was given 50?4?2 ?g/d of beclomethasone dipropionate nasal spray in all medicament groups,Treatment time was 3 months. The symptom scores (SS)and visual analogue scale(VAS)were recorded. RESULTS Effect assessment showed that both methods had significant repressive effect on allergic symptoms,the effect of surgery group was better than that of medicament group at the 14th day,28th day and 3th month in cases with swelling of inferior turbinate. Difference between the surgery group and medicament group in cases without swelling of inferior turbinate had no statistic significance. CONCLUSION Both coblation plasma surgery and beclomethasone dipropionate nasal spray are effective to treat perennial allergic rhinitis. But coblation plasma surgery is better than medicament in cases with swelling of inferior turbinate.

AIM: To optimize the milling and extraction rate for Naolisu Granules (Rhizoma Acori Tatarinowii, Radix Notoginseny, Pheretima Radix et Rhizoma Rhei, Radix Curcuma, Radix Ginserg Rubra, etc.). METHODS: The granularity of powder was determined by different micropowder processes. The process was studied by orthogonal design with the content of volatile oil, the yield of extract and the content of emodin. RESULTS: The optimum process of milling was that coarse powder was micropulverized for 20 min at -8℃ ~ -12℃ . The optimum extraction of volatile oil was distillated for 4 hs after volatile medical materials were macerated for 1h with 7 times amount of water. The optimum process of percolation was percolated by 300mL of 75% alcohol with 3.0mL?kg -1 ?min -1 after the medical material powders were macerated for 6 hs. CONCLUSION: These optimum processes are suitable for preparation of Naolisu Granules.

Objective:To conduct a clinical tretrospective study on the effect of Silymarin Meglumine Tab on acute and chronic hepatitis B and to explore the related clinical significance. Methods: 41 cases and 205 cases of hospitalized patients pathologically diagnosed as acute and chronic hepatitis B respectively by liver tissuse puncture were divided into three group: ① Silymarin Meglumine Tab group; ② Ganyanling group; ③ complex group consisting of Silymarin Meglumine Tab and Gangyanling and diammonium glycyrrhizinate. To detect the index of routine liver function test before and after the treatment and analyze the hospitalization treatment course. Results: Compared with before treatment, liver functions of acute and chronic hapatitis B were improved to certain extent within each group after treatment (P0.05). The hospitalization treatment time of acute hepatitis B of the three group were almost the same, but the hospitalization treatmeng time of chronic hepatitis B of the Silymarin Meglumine Tab group was 2-4days less than that of the Ganyanling group and the complex group. Conclusion: As far as Silybini Meglumine Tab was concerned, it was better for chronic hepatitis B than acute hepatitis B because it was less complicated to administer the medicine, relieving the liver's burden of metabolism, and hospitalization treatment time was shorter, relieving patients' financial burden,which suggested that it was important to administer proper amount of medicine while taking into consideration protecting the liver's compensation function. If consideration was given to stimulating liver microcirculation with small dosage of TCM, so as to promote the exchange of the liver metabolite in blood, or detoxication and expulsion of toxin, it was likely to be more advantageous to the restoration of liver function and the liver tissue structure.
