RESUMEN

<p><b>OBJECTIVE</b>To evaluate the short-term efficacy and long-term preventive effect on recurrence in prevention and treatment of children allergic rhinitis treated with the multiple therapy at Dazhui (GV 14) as the main acupoint and acupoint plaster therapy.</p><p><b>METHODS</b>One hundred and twenty cases of children allergic rhinitis were randomized into a triple-strong stimulation therapy group and an acupoint plaster therapy group, 60 cases in each one. In the triple-strong stimulation therapy group, Dazhui (GV 14) was the main acupoint, combined with one of Feishu (BL 13), Zhiyang (GV 9) and Shenshu (BL 23) accordingly. The heavy needling technique was adopted with the three-edged needle, followed by heavy cupping and heavy moxibustion. The treatment was given once every 3 days, continuously for 10 times. In the acupoint plaster therapy group, the acupoints selected were same as the triple-strong stimulation therapy group. The self-prepared Chinese herbal plaster was used, 4 h to 8 h each one time, once every 3 days, continuously for 10 times. The changes in the symptom and physical sign scores were observed before treatment, after treatment and in 6 months follow-up visit after treatment in the two groups. The clinical efficacy was compared between the two groups.</p><p><b>RESULTS</b>After treatment and in 6 months follow-up visit after treatment, the symptom scores, physical sign scores and symptom scores of each item were different signi ficantly as compared with those before treatment in the triple-strong stimulation therapy group (P<0.01, P<0.05), and the results in the triple-strong stimulation therapy group were better than those in the acupoint plaster therapy group (all P<0.01). In 6 months follow-up visit, the total effective rate was 94.6% (53/56) in the triple-strong stimulation therapy group and was 25.9% (15/58) in the acupoint plaster therapy group, indicating the significant difference (P<0.001).</p><p><b>CONCLUSION</b>The triple-strong stimulation therapy at Dazhui (GV 14) achieves the superior effect on the prevention and treatment of children allergic rhinitis as compared with the acupoint plas ter therapy and has good long-term effect of the prevention from recurrence.</p>

RESUMEN

The leaves surface of Puccinelia tenuiflora seedling under stress of different concentration of Na(2)CO(3) was observed with scanning electron microscopy and X-ray electron probe micro analyzer. All the results indicated that varied salts crystalline distributing in stomatal apparatus on P. tenuiflora leaves surface could be observed by means of frozen-dried sampling. In the case of no stress, these leaves had many kinds of sediments such as Na, K, Ca, Mg, Zn, Cu, Cl, P, S, Si on their surface. When there was stress of Na(2)CO(3), the percentage content of each sediment would have an non-linear relationship to stress. As the concentration of Na(2)CO(3) increased, the percentage contents of Na, Cu, Zn, P, S generally decreased while that of K, Ca, Mg, Si generally increased. The ratio of K/Na also changed the same way as the later. From these results, we concluded, under stress of alkali and salts, P. tenuiflora leaves could exude salts through their stomata or together with wax secretion and these ways might participate many regulation process of P. tenuiflora leaves cells, for example in ion balancing, osmosis regulating and water metabolizing.

RESUMEN

In order to observe clinical therapeutic effects of different acupuncture and moxibustion methods on acute lumbago, the patients of acute lumbago were randomly divided into four groups: group A, filiform needle treatment group; group B, filiform needle plus cupping group; group C, filiform needle plus blood - letting puncture and cupping group; group D, filiform needle plus blood - letting puncture, cupping and moxibustion group. All the patients were treated respectively 5 and 10 times. Results showed that there were significant differences in the effective rate and cured rate as the group C and D compared with group A and B respectively (P
