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.

Research on novel pullulanase has major significance on the domestic industrialization of pullulanase and the breakdown of foreign monopoly. A thermophilic bacteria LM 18-11 producing thermostable pullulanase was isolated from Lunma hot springs of Yunnan province. It was identified as Anoxybacillus sp. by 16S rDNA phylogenetic analysis. Full-length pullulanase gene was cloned from Anoxybacillus sp. LM18-11. The optimum temperature of the pullulanase was between 55 and 60 degrees C with a half-life as long as 48 h at 60 degrees C; and its optimum pH was between 5.6 and 6.4. V(max) and K(m) of the pullulanase was measured as 750 U/mg and 1.47 mg/mL, which is the highest specific activity reported so far. The pullulanase crystals structure showed a typical alpha-amylase family structure. The N-terminal has a special substrate binding domain. Activity and substrate binding were decreased when the domain was deleted, the V(max) and K(m) were 324 U/mg and 1.95 mg/mL, respectively. The pullulanase was highly heterologous expressed in Bacillus subtilis by P43 promoter. The extracellular enzyme activity was 42 U/mL, which increased more than 40 times compared to the initial strain. This pullulanase has good application prospects.

Objective To investigate the effecacy of open reduction internal fixation in cases with rib fracture. Methods The pain scores,respiratory related clinical indicators change of 81 rib fractuure cases underwent open reduction internal fixation surgery were ob-served. A comparison was made between the surgical group and the non-surgical group of 37 cases on pain scores trend and hospital stay. Re-sults All operations were successfully completed and postoperative recovery was good. Postoperative pain scores and respiratory rate was sig-nificantly lower(P=0. 000),Oxygen saturation was significantly higher(P=0. 002),the proportion of expectoration difficult,dyspnea and ac-tivities inconvenience were significantly lower(P<0. 05). Pain scores of surgical group significantly decreased after surgery peak hours that was the fourth day hospitalized,but the overall decline of pain scores in non-surgical group was slow. The hospital stay between the surgical group and the non-surgical group was not significantly different(P=0. 084). Conclusion The efficacy of open reduction internal fixation is significant to rib fracture with exact surgery indications,and appropriate timing of surgery is the fourth day after admission.

Objective: To observe the effect of moxibustion therapy on heme oxygenase-1 (HO-1) and monocyte chemoattractant protein-3 (MCP-3) protein expressions in the colonic mucosa of rats with Crohn's disease (CD), and to explore the intestinal mucosal immune mechanism of moxibustion therapy in treating CD. Methods:The CD rat model was established using the internationally accepted Morris method. The rats were randomly divided into a model group, a herbal cake-partitioned moxibustion group, a mild moxibustion group, a cigarette moxibustion group and a hot compress group, which were compared with the normal group. Except the normal group and the model group, rats in the other groups accepted different moxibustion therapies on bilateral Tianshu (ST 25). Hematoxylin-eosin (HE) staining was conducted and the pathological changes of the colon were observed under light microscope; the expressions of HO-1 and MCP-3 protein in rat’s colonic mucosa were determined by immunohisto-chemistry. Results:Compared with the normal group, rats in the model group showed mucosal defect, villus destruction or loss, submucosal congestion and edema, glandular destruction or disappearance, reduced goblet cells, ulcer formation, significantly increased positive target area and positive target integral optical density of HO-1 and MCP-3 protein expression (allP<0.01). After treatment, compared with the model group, colonic mucosa was significantly improved in the herbal cake-partitioned moxibustion group and the mild moxibustion group, which mainly showed that the intestinal glands were arranged regularly, ulcer surfaces were covered by the neoformative epitheliums, or intestinal ulcers were replaced by the nascent granulation tissue, and submucosal edema was alleviated, with a small amount of inflammatory cell infiltration. The total areas and the integral optical densities of the positive targets for rat’s colonic mucosa HO-1 and MCP-3 protein expressions were decreased (allP<0.01). Compared with the cigarette moxibustion group and the hot compress group, the total areas and the integral optical densities of the positive targets for rat’s colonic mucosa HO-1 and MCP-3 protein expressions were significantly decreased (allP<0.01) in the herbal cake-partitioned moxibustion group and the mild moxibustion group. Conclusion:Herbal cake-partitioned moxibustion and mild moxibustion can significantly improve the inflammatory response of colonic mucosa in CD rats. It can down-regulate the expressions of HO-1 and MCP-3 proteins in the colonic mucosa of CD rats, which may be one of the mechanism in intestinal mucosal immunity caused by moxibustion therapy.
