BACKGROUND: It is thought in traditional Chinese medicine that dogday moxibustion (DDM) has good clinical effect in treating bronchial asthma. Study of its influence on soluble cellular adhesion molecules in patients with bronchial asthma can help to well understand its mechanism.OBJECTIVE: To observe the effect of dog-day on soluble cellular adhesion molecules in patients with bronchial asthmaDESIGN: Self-control, case-control observationSETTING: College of Acupuncture and Manipulation and Clinic of the Department of Acupuncture and Moxibustion of the First Affiliated Hospital, Guangzhou University of Traditional Chinese Medicine.PARTICIPANTS: Totally 28 patients with bronchial asthma receiving dog-day moxibustion in the Clinic of the Department of Acupuncture and Moxibustion, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine from July to August 2004 were set as dog-day moxibustion group, and 10 concurrent health volunteers were set as normal control group.METHODS: According to the principle of "treating winter diseases in summer", the Chinese medicine which consists of such herbs as Baijiezi(Semen Sinapis Albae ), Mahuang(Herba Ephedrae ), Xixin (Herba Asari ),Gans ui (Radix Kansui ), Yanhu (Rhizoma Corydalis ) was stuck on the points such as Feishu, Dingchuan, Fengnen, Bailao, Shenshu. Point selection was at the two sides, and a lumpy salve was stuck on the point with adhesive tape. Three to six hours for adult and one to two hours for children in each sticking duration; and the operation was respectively done on the first (July20), second (July 30) and third (August 9) dog-day.MAIN OUTCOME MEASURES: Short-term effect 3 months later was observed, the levels of soluble cellular adhesion molecules and IgE were assayed before and 10 days after treatment, and comparison with normal control group was performed. The indexes of the patients before treatment were performed Pearson correlation analysis.RESULTS: Twenty-eight patients and 10 healthy persons all entered result analysis. [1] Intercellular adhesion molecule-1 level was significantly higher before treatment in dog-day moxibustion group than that after treatment in the dog-day moxibustion group and that in the normal control group [(281.39±64.58 ), (256.95±44.22), ( 194.30±39.05 ) μg/L,P ＜ 0.01].[2]Vaso-cellular adhesion molecule-1 level was significantly higher before treatment in the dog-day moxibustion group than that after treatment in the dog-day moxibustion group and that in the normal control group [(234.79±89.75), (185.80±84.41), (128.85±51.28)μg/L,P ＜ 0.01]. [3]IgE level was significantly higher before treatment than that after treatment in the dog-day moxibustion group and that in the normal control group [(482.61±123.43), (418.96±134.18), (161.53±43.64)μg/L,P＜ 0.01]. [4]Pearson correlation analysis result: Intercellular adhasion molecule-1 level is significantly positively correlated with IgE and vascular intercellular adhesion molecule-1 level (r =0.641,0.449 ,P ＜ 0.01,0.05). [5]Effect: Total effective rate was 93% (26/28)in the treatment of bronchial asthma with dogday moxibustion . The type of the symptoms, with blister or not, course of disease and condition of disease had no significant influence on effect (P＞ 0.05).CONCLUSION: Dog-day moxibustion may effect through inhibiting the expression of adhesion molecule or inhibiting leukocyte to adhere endothelial cell directly so as to reduce the infiltration of inflammatory cells.

【Objective】 To observe the effect of acupuncture on immune organs(thymus and spleen) and T lymphocyte subtypes of CD3,CD4 and CD8 in rats with dysmenorrhea.【Methods】Thirty SD rats were randomized into normal control group,model group and electroacupunture(EA) group.Except the normal control group,rats in other groups received intraperitoneal injection of diethylstilbestrol and oxytocin to induce dysmenorrhea.EA group received EA on bilateral acupoints of Sanyinjiao and Guanyuan additionally.After 10-day treatment,body-stretching rate,the pathological changes of thymus and spleen,and blood CD3,CD4 and CD8 levels in the three groups were observed.【Results】In the model group,body-stretching rate was 100%,the pathological changes of thymus and spleen were obvious,and blood CD3 and CD4 levels were decreased as compared with the normal control group(P

Objective To determine the influencing factors of post-stroke depression by machine learning.Methods Stroke patients' medical records (688 cases eligible) were extracted from record system,including age,gender,pulse manifestation,complexion,tongue quality,fur,Chinese medicine intervention,body mass index (BMI),blood pressure,blood glucose,blood triglyceride,blood total cholesterol,smoking history,drinking history,depression family history,stroke lesion site in imaging,as well as the final depression judgment.Single rule algorithm (1R) was adopted to learn.The risk factors influencing post-stroke patients' depression in extracted information were determined.Then the cases collected were divided into the training dataset (500 cases) and the test dataset (188cases).Optimal discriminant results were obtained by random forest model.Results Single rule algorithm showed that the most important influencing factor of post-stroke depression was stroke lesion site.By computer speculation,stroke lesions in the frontal and temporal lobes were most prone to post-stroke depression.Basal ganglia,brain stem,cerebellum,medulla oblongata and occipital lobe lesions were less likely to cause depression.The accurate classification rate could amount to 88.95％ (612/688 cases).Random forest model determination was made in the former 500cases in the training dataset.The total correct rate of determining depression was 98.2％.The total correct rate of determination in 188 cases of the test dataset was 99.47％.Six hundred and eighty-eight patients' data were learnt by random forest model.The total correct rate was 98.84％.The importance measure results showed that top 3 important indexes of post-stroke depression were lesion site,Chinese medicine intervention and depression family history.Conclusion Patients with lesions in the frontal & temporal lobes and depression family history were most prone to post-stroke depression.

Objective To observe the efficacy of electroacupuncture(EA) on the acupoint combination of He-(sea) points, front-mu points, and shu-points(abbrev. He-Mu-Shu) for the treatment of functional diarrhea, and to explore the effect of He-Mu-Shu point combination EA on the anxiety of patients. Methods A randomized controlled clinical trial was performed in 62 functional diarrhea patients. All of the patients were randomly divided into He-Mu-Shu group(32 cases) and medicine group(30 cases). He-Mu-Shu group was treated with EA on unilateral Quchi, Shangjuxu, Tianshu, Dachangshu point alternatively, and medicine group was treated with oral use of Loperamide hydrochloride capsules. Both groups were treated for 4 continuous weeks. Defecation frequency, stool property and anxiety scores were observed before treatment and 2, 4 weeks after treatment. Results After treatment, weekly defecation frequency, stool property and anxiety scores were improved in both groups, and the differences were statistically significant compared with those before treatment(P < 0.05). He-Mu-Shu point combination EA had better effect on improving weekly defecation frequency, stool property and anxiety scores of functional diarrhea patients than Loperamide hydrochloride capsules, and the differences were statistically significant (P < 0.05). Conclusion The clinical efficacy and anxiety-relief action of He-Mu-Shu point combination EA on functional diarrhea are superior to oral use of Loperamide hydrochloride capsules.
