Unclear clinical orientation in practice has become one of the common problems with the effective application of famous and excellent Chinese herbal drugs, consequently restricting their development. The authors suggest that there are three aspects to be considered in dealing with this problem. Clinical evaluation and orientation of the famous and excellent Chinese herbal drugs is an important task, and it is also a requirement for the internationalization of traditional Chinese medicine. Literature evaluation-pharmacology research-clinical expertise analysis method will establish a theoretical basis and method for post-marketing development of famous and excellent Chinese patent drugs.

Objective Vertebral benign and malignant tumors were intractable in the treatment. Previous treatment methods had their own deficiency. The introduction of percutaneous vertebroplasty brought a breakthrough in the treatment. The initial experience of the treatment of vertebral malignant and benign tumors with percutaneous vertebraplasty was analyzed in this clinical research.Methods and materials The treatment of seven cases of vertebral hemangiomas and 11 cases of vertebral malignant tumors were reported. Unipedicular or bipedicular approaches were used in 17 cases, and in one case of cervical hemangioma, the cervical anterior-lateral approach was adopted. 15-20% of bone cement was mixed and injected into the vertebral lesions and made to distribute and cast in the lesions. Results Good results were got in all the 18 cases. After 0.5-7ml of cement was injected into the lesions. The complete relief was got in 10 cases and sub-complete relief was achieved in 6 cases and medial relief was got in two cases. One to nine months of postoperative follow-ups found no recurrences.Conclusions The treatment of vertebral benign and malignant tumors with percutaneous vertebraplasty was mini-invasive, safe, and effective.

Germination of the seeds of Bupleurum chinense and B. falcatum activated by exogenous hormones of dif ferent concentrations was studied. The hormones used were GA3, 6-BA and IAA. The optimum concentration of the 3 hormones that activated the seed germination of B. chinense was 50?g/ml,while that for B. falcatum was 200?g/ml, 100?g/ml and 25?g/ml respectively. Among the 3 hormones, 6-BA showed the greatest effect on the 2 species of Bupleurum L. 50?g/ml 6-BA raised the germination rate of the seeds of B. chinese from 57.5 % to 84. 5 % and 100?g/ml 6-BA raised the germination rate of the seeds of B.falcatum from 28. 5 % to 76.0%

OBJECTIVETo observe the differences in timely effectiveness of immediate analgesia on acute migraine between electroacupuncture (EA) at shaoyang meridian points and non-meridian points.

METHODSThe randomized controlled trial method was adopted. One hundred and ten cases of acute migraine were randomized into two groups. 55 cases in each one. In the observation group, EA was applied to Fengchi (GB 20), Waiguan (TE 5), etc. In the control group. EA was applied to non-meridian points. Only one treatment was given, and the nee dies were retained for 30 min in the two groups. Separately. at 10 time points, named before acupuncture, in 5 min, 10 min. 20 min and 30 min (at the moment of needle removal), 1 h, 2 h, 4 h, 6 h and 8 h after acupuncture, the pain intensity numerical rating scale (PI-NRS) was adopted to evaluate the pain severity and the adverse reac tion was recorded.

RESULTS(1) The effective rate of imnmediate analgesia was 87. 3% (48/55) in the observation group. significantly higher than 52.7% (29/55) in the control group (P<0.01). (2) NRS of each group was re duced at each time point, from 5 min to 8 h after acupuncture (all P<0.01). (3) NRS score at 30 min after acu puncture in the control group was obviously lower than that in the observation group (P<0.05), but the scores in 2 h, 4 h, 6 h and 8 h after acupuncture in the observation group were lower apparently than those in the control group (all P<0. 01). The differences in the scores in 5 min, 10 min, 20 min and 1 h after acupuncture were not significant (all P>0. 05). (4) For the reducing amplitude of NRS score at the same time point after acupuncture, the results in 20 min, 30 min and 1 h in the control group were higher apparently than those in the observation group (all P<0. 05). But, in 2 h, 4 h, 6 h and 8 h, the results in the observation group were higher apparently than those in the control group (all F<0.05). The differences in 5 min and 10 min after acupuncture were not significant (both P>0. 05). (5) In 24 h after acupuncture, the recurrence rate of migraine was 12. 7% (7/55) in the observation group, which was lower obviously than 34. 5% (19/55) in the control group (P<0. 05). The adverse reaction was not found in the two groups.

CONCLUSIONEA at the shaoyang meridian points achieves the definite immediate analgesia effect on acute migraine and presents the time effectiveness of analgesia.
