为了探究不同材质的井窖移栽成穴头在井窖制作过程中对脱土减阻、入土能力和井窖成型质量的影响,利用UG软件建立三维模型,基于ANSYS有限元分析软件平台对钢制成穴头和尼龙-钢制成穴头进行了模态仿真分析。取前6阶模态,对2种成穴头的固... 为了探究不同材质的井窖移栽成穴头在井窖制作过程中对脱土减阻、入土能力和井窖成型质量的影响,利用UG软件建立三维模型,基于ANSYS有限元分析软件平台对钢制成穴头和尼龙-钢制成穴头进行了模态仿真分析。取前6阶模态,对2种成穴头的固有频率和最大振幅进行对比。结果表明:尼龙-钢制成穴头前6阶模态的平均振幅大于钢制成穴头,是其1.4倍;尼龙-钢制成穴头前6阶模态下各阶固有频率均小于钢制成穴头,低阶频率下更容易被激发发生共振变形;从振型发生的部位比较,尼龙-钢制成穴头的各阶振动变形均主要发生在部件下部小端处。由此得出结论:相对于钢制成穴头,尼龙-钢制成穴头在井窖的制作过程中,能增强其脱土减阻潜力,并增强了井窖壁强度,提高了成穴头入土能力。该研究可为成穴头材料的选择和井窖移栽机设计提供参考。 展开更多

Objective To probe into the impacts on the expression of vascular endothelial growth factor (VEGF) in ischemic brain tissue treated with cluster puncture on scalp acupoints in rats, Methods 128 rats were randomized into pseudo-operation group, model group, scalp-needling group and cluster-needling group, In scalp-needling group, penetration method was used on the focal side from Bǎihuì (百会 GV20) to Qǔbīn (曲鬓 GB7), and in cluster-needling group, penetration method was used on both sides from GV20 to GB7, and a common needling on GV 20. Needles were punctured 2 mm in depth, constantly rotated for 10min, retained for 2 h. Immunohistrochemical method was applied to determine VEGF expression and microvessel density (MVD). Results With the intervention of cluster puncture on scalp acupoints, VEGF: expressions on every time-spot after ischemia were enhanced apparently, superior to those in scalp-needling group. On the three time-spots of the 7^th, 14^th and 21^st days, MVD was increased after cluster puncture on scale acupoints, superior to those in scalp-needling group. Conclusion Cluster puncture on scalp acupoints up-regulated VEGF expression and promoted regeneration of microvessel. 展开更多

Objective To observe the therapeutic effect of electro acupuncture at QIǖXǖ(丘墟GB40) for treating migraine and provide clinical study for Acupoints Dictionary of People's Republic of China. Methods Multi-center (3 First-Class hospitals) study was adopted, and the involved 3 hospitals did clinical observation according to the requirements of the project. The methods are as follows. All cases were randomized into treatment group and control group according to their sequence. QIǖXǖ(丘墟GB40) was selected in treatment group, while Tiānshū (天枢 ST25) was selected in control group. Both groups were performed electro acupuncture, and syndromes indexes of migraine and 5-HT were observed before and after treatment. All data were analyzed by statistic software SPSS11.5. Results There was significant difference of VAS margin between two groups in each center and the combined center (u= -3. 362, P=0. 001 ). There was significant difference of therapeutic effect of 4-week treatment between two groups in each clinical center and the combined center. The therapeutic effect of 3-month treatment between two groups in No. 1 and No. 3 hospitals, showed significant difference, the treatment group was better; while that of No. 2 hospital had no obvious difference. The therapeutic effect of 6-month treatment between two groups in each center and the combined center had significant difference, the treatment group was better. Conclusion The therapy of electro acupuncture at QIǖXǖ(丘墟GB40) is effective for migraine. 展开更多

Objective To probe into the function mechanism of penetration therapy with head electrical acupuncture on Parkinson's disease. Methods Microinjection of 6-hydroxydopamin (6-OHDA) on the left cor- pus striatum was adopted to prepare rotation model of Parkinson^s disease in rat. Penetration therapy with head electrical acupuncture was administered in treatment. Normal group, sham-operation group, model group and penetration therapy group were set up. (1)lmmunohistochemical (IHC) method was used to test the morphology and count of positive cell of tyrosine hydroxylase (TH). (2)RT-PCR technology was used to detect the expression of nestin mRNA of neural stem cell (NSC). Results (1)Compared with model group, in pene- tration therapy group, the expressions of TH-positive neurons in immune response were increased in areal density (AD), numerical density (ND) and integrating optic density (P〈0.05). (2)Compared with model group, in penetration therapy group, the expression of nestin mRNA was increased (P〈0. 05). Conclusion Penetration therapy with head electrical acupuncture promotes the proliferation of endogenous neural stem cells in substantia nigra of rat model of Parkinson's disease. 展开更多

Objective: To observe the therapeutic effect of bloodletting plus point implantation of catgut in the treatment of 67 cases of vascular headache. Methods: A total of 107 cases of vascular headache patients were divided into treatment group (n=67) and control group (n=40). Bilateral Taiyang (EX-HN 5) and Jiaosun (TE 20) were pricked with a needle to let a little blood out, once every 4 days. Bilateral Fengmen (BL 12) and Ganshu (BL 18) were used for embedding catgut, once every 16 days. Patients of control group were ordered to take Rotunding, Oryzanol and Nimodipine, 3 times daily. Results: After 16 days’ treatment, of the 67 cases in treatment group, 26 were cured, 37 responded with improvement in their symptoms and 4 failed; while of the 40 cases in control group, 10 were cured, 19 responded with improvement in their symptoms and 11 failed. The total effective rate of treatment group was significantly superior to that of control group (P<0.01). In addition, the time of headache disappearance of treatment group was strikingly shorter than that of control group; while the duration of sleep of treatment group was strikingly longer than that of control group (P<0.01). Conclusion: The therapeutic effect of acupoint bloodletting plus acupoint embedding of catgut is superior to that of Western medicine in the treatment of vascular headache. 展开更多

Objective: To explore a new effective approach for treatment of the local irritable symptoms and signs resulted from myoporthosis operation. Methods: 263 cases of radial keratotomy outpatients were divided into control group (n=49, 90 eyes) and treatment group (n=214, 412 eyes). Patients of control group were treated with 0.5% Chloramphenicol eye drops, 3 times daily, 1-2 drops/time, and with 0.5% Erythromycine eye ointment every night. In treatment group, patients were treated with acupoint and hand reflection area digital pressing method except with the same eye drops and eye ointment. Body acupoints used were Cuanzhu (BL 2), Yuyao (EX HN 4), Sizhukong (TE 23), Sibai (ST 2) and Taiyang (EX HN 5). The hand reflex areas used were Eye Area, Liver Area, Kidney Area, Spleen Area, Heart Area and Lung Area. Five days constituted a therapeutic course. Results: Following 3 courses (15 days) of treatment, the markedly effective rate and total effective rate of treatment group and control group were 74.51% and 38.89%, 94.17% and 66.67% respectively. There was a significant difference between two groups in the total effective rate (P<0.05), showing the therapeutic effect of treatment group being better than that of control group.

Objective To observe therapeutic effects of scalp acupuncture at close acupoints combined with rehabilitation training on balance functions of children with cerebral palsy (CP). Methods Sixty children with CP were randomly divided into a scalp acupuncture combined with rehabilitation training group (group SA+RT) and a rehabilitation training group (group RT) with 30 cases in each group. Conventional rehabilitation therapy and balance training were applied in group RT, and scalp acupuncture at close acupoints in the parietal region and sub-occipital region was added besides rehabilitation training in group SA+RT. Balance functions were evaluated by using Berg rating scale, and abilities of daily living were estimated by using rating scale for activities of daily living (ADL). Results After treatment, both Berg scores for balance and ADL scores were significantly improved in both groups (all P0.05), and the improvement in group SA+RT was more obvious than that in group RT ( both P0.05). Conclusion Combination of scalp acupuncture at close acupoints with rehabilitation training is superior to simple rehabilitation training in improving balance functions and activities of daily living in children with cerebral palsy. 展开更多
