Methods: 48 Wistar rats were randomly divided into I R group, sham operation group, DN stimulation (S) group and FN S group, and each of the later two groups were further divided into 3 groups according to fore stimulation duration (one day, 4 days and 7 days). The middle cerebral artery occlusion and reperfusion(MCAo R) model was performed in Wistar rats using intraluminal cauterized catgut ball blocking method. Cerebellar FN and DN (Dentate Nucleus) were stimulated electrically for 1 hr, one day,4 days and 7 days before MCAo R(1.5 hr/24 hr). PKC γ, PKC δ protein expression was determined with immunohistochemical staining technique. Results: PKCγ and δ positive reaction cells distributed in cerebral cortex, hippocampus and the ischemic half shadow area. There were no significant differences among I R group, sham operation group, DN stimulation (S) subgroups (1 day, 4 days and 7 days) in PKCγ and δ positive cell counts (P>0.05), but in comparison with DN stimulation subgroups, the positive cells in FN stimulation subgroups were significantly fewer (P<0.01), which even lasted 7 days (P<0.05). Conclusion: Cerebral ischemia can induce abnormal expression of PKC γ and PKC δ, and FN fore stimulation generated down regulation of PKCγ and δ expression may contribute to its protective effect on cerebral ischemia.
摘要:目的 :研究不同强度的电针对大鼠脑内P物质表达的影响。方法 :在电针大鼠下肢“足三里”穴位后 ,用免疫组织化学的方法观察了电针后 2 4hr大鼠尾壳核、杏仁核、下丘脑室旁核、下丘脑前区、导水管周围灰质P物质表达的变化。结果 :电针组较对照组上述部位P物质表达阳性细胞数明显增高。结论 :电针可引起脑内上述部位P物质表达增高 ,而P物质表达的增高可能在调节机体许多生理功能中起重要作用Objective: To study the influence of different intensity of electroacupuncture (EA) on substance P(SP) expression in rat brain. Methods: Nine SD rats were randomly divided into control group, high intensity EA group and low intensity EA group. "Zusnali" (ST 36) was punctured with filiform needles and stimulated electrically by setting the stimulating strength being 1 mA (low intensity) and 5 mA (high intensity), wave width 0.1 ms, frequency 50 Hz and duration of 30 min. SP expression was displayed with immunohistochemical method. Results: Twenty four hours following EA stimulation, SP expression positive cells were found in caudate putamen, hypothalamic paraventricular nucleus, anterior hypothalamic area, amygdaloid nucleus and periaqueduct grey matter. SP expression positive cells in these nuclei or area in two EA groups were significantly more than those of control group (P<0.05), while those of low intensity EA group were evidently more than those of high intensity EA group (P<0.05). Conclusion:EA can induce up regulation of SP expression in the aforementioned brain regions and the resultant enhancement of SP expression may play an important role in regulating a variety of physiological functions in the body.

Methods: 50 guinea pigs were randomly and evenly divided into five groups: ① control group,②asthma group,③ moxibustion group,④ L NAME (non selective inhibitor of NO) group,and ⑤L NAME + moxibustion group. Asthma model was established by intraperitoneal injection of 10% egg albumin saline (1 mL) and inhaling 1% aerosol egg albumin in guinea pigs. The 3H QNB(quinuclidinyl benzilate) combined Bmax and equilibrium dissociation constant (Kd) of M receptor on the lung tissue cell membrane were calculated using Scatchard formula according to the detected radioactivity value with radioaligand binding assay, and NO levels of plasma, bronchoalveolar lavage fluid(BALF)and lung tissues were assayed according to instructions of the reagent kit. Bilateral "Feishu" (BL 13), "Dazhui" (GV 14) and "Dingchuan" (EX B 1) were moxibustioned for 20 min.Results: Results indicated that Bmax level of 3H QNB combined M receptor of asthma group and asthma+L NAME group increased significantly in comparison with those of control group (P<0.01); there were no significant differences between moxibustion and control groups, and between moxibustion+L NAME and control groups, suggesting an inhibitory effect of moxibustion on Bmax. In spite of being higher of kd value in moxibustion group, no significant differences were found among the 5 groups (P>0.05). Regarding NO content changes, there were no significant differences among the 5 groups in plasma NO; while BALF and lung tissue NO contents of asthma group increased considerably in comparison with the other 4 groups (P<0.01), but no significant differences were found between moxibustion, or L NAME, or moxibustion+L NAME groups and control group, indicating a down regulative action of moxibustion on BALF and lung tissue NO levels. In asthma model group, moxibustion group and moxibustion+L NAME group, a positive correlation between nitric oxide level and Bmax of M receptor exists(γ=0.732, 0.718, 0.716,P<0.05),and L NAME had no obvious affection on the Bmax of M receptor.Conclusion:Moxibustion can suppress asthma induced increase of NO contents in the lung tissues and BALF and Bmax level; and there exists a positive correlation between NO level and Bmax of M receptor.

Methods:SD rat CCI (chronic constriction injury) hyperalgesia model was used as the neuropathic pain model, and hyperalgesia score employed as the sign of neuropathic pain. In single EA treatment experiments, 12 hyperalgesia rats were randomly divided into control group and EA group, while in multiple EA treatment experiments, 20 hyperalgesia rats were randomly divided into control and EA groups. Results: ① Before single EA treatment, the basal hyperalgesia scores of control group and EA group were -3.035±0.222 and -2.870± 0.332 respectively, having no significant difference between them. Following single EA stimulation, the absolute values of the hyperalgesia score decreased significantly from 20 min to 60 min after EA in comparison with control group (P<0.05). ② In multiple EA treatment experiments, the basal hyperalgesia scores of EA group and control group were -2.030±0.170 and -2.239±0.268, showing no significant difference between them. Along with increase of EA times, the absolute values of the hyperalgesia score decreased gradually. On the 12th, 14th, 21st, 24th, 26th and 28th day, the hyperalgesia scores were significantly lower than those of control group (P<0.05) and those of the 3rd week (21st~28th day after operation) were even more evidently than those of the first two weeks (P<0.05). Results showed that multiple EA treatments had an obviously accumulative effect on analgesia. Conclusion: EA could produce immediate analgesia action and have an accumulative effect.

Methods: A total of 40 rats were randomly and evenly divided into normal control group, model group, hormone (hydrocortisone) group and acupoint apitherapy group. RA model was established by injecting Freund's adjuvant (0.05 mL)into the right hind paw. For rats of hormone group, intraperitoneal injection of hydrocortisone (10 mg/2 mL) was performed. In acupoint apitherapy group, "Shenshu"(BL 23), "Zusanli"(ST 36), "Mingmen"(GV 4) and "Dazhui"(GV 14) were stimulated with bee needle pricking method. IL 1β mRNA and IL 6 mRNA expression of synovial tissues (right knee joint capsule) was detected using PCR microplate sandwich hybridization technique. Results:In comparison with normal control group, IL 1β mRNA and IL 6 mRNA expression of synovial tissues increased considerably in model group (P<0.01). There was no statistical difference between acupoint apitherapy group and hormone group in IL 1β mRNA and IL 6 mRNA expression, but the expressions in these two groups were significantly weaker than those of model group. Conclusion:Acupoint apitherapy could induce upregulation of IL 1β mRNA and IL 6 mRNA expression in RA rats , which may be responsible for apitherapy generated relief of symptoms and signs of RA.
摘要:目的 :观察针刺对心脏植物神经的调节作用。方法 :采用心率变异性频谱分析法 ,对心脏植物神经做药物的逆同向干预后的针刺效应进行分析研究。结果 :植物神经被部分阻断后 ,针刺效应具有去药物干预样的作用。结论 :针刺疗法具有双向的良性调节作用 ,对心率变异性的调节必须依赖于植物神经 ,对心肌具有保护作用Objective: Observing the action of acupuncture on cardiac autonomic nerve activity in volunteer subjects.Methods: Twelve volunteer healthy subjects were evenly and randomly divided into Atropine group and Metoprolol group. Subjects of Atropine group were given intravenously with Atropine 1 mg, followed by puncturing bilateral Neiguan (PC 6) and Jueyinshu (BL 14) and stimulating them electrically with frequency of 0.6~0.8 Hz, 15~30 V, and duration of 10 min. In Metoprolol group, 6 subjects were ordered to take Metoprolol 12.5 mg orally, then EA was applied to Neiguan (PC 6) and Jueyinshu(BL 14)for 10 min. Heart rate variability (HRV) was analyzed to evaluate the effect of acupuncture on medicine induced abnormal changes of cardiac autonomic nerve activity. Results: Following injection of Atropine, low frequency (LF) component of HRV was increased slightly, while the high frequency (HF) component declined significantly (P<0.01), and LF/HF got smaller. After EA, both LF and HF, particularly HF component increased significantly (P<0.05). Following administration of Metoprolol, LF reduced while HF increased, and LF/HF reduced considerably in comparison with pre administration of Metoprolol (P<0.01). When EA was given for 10 min, LF increased evidently (P<0.05) and HF also increased, and LF/HF got to close to normal level. The findings indicated that acupuncture could antagonize medicine induced disorder of cardiac vegetative nerve activity.Conclusion: Acupuncture possesses dual directional regulative action on cardiac sympathetic and vagal nerve activities and can protect myocardial functions effectively.

摘要:本文对胰岛素抵抗 (insulinresistance,IR)的机理研究进展作一简单概述 ,据此阐明针刺具有改善胰岛素抵抗的作用 ,并就针刺干预胰岛素抵抗的可能作用靶点提出构想 ,认为在受体前、受体及受体后水平来研究针刺改善胰岛素抵抗 ,最有可能揭示其作用机理 ,为进一步研究针刺改善胰岛素抵抗提供思路In the present study, the authors review some advances of the research on insulin resistance (IR) and the possible action target sites of acupuncture in relieving IR related diabetes, hypertension, adiposis, etc. Findings show that pre receptor and post receptor factors may be responsible for the occurrence of IR. Pre receptor factors generally include ① Insulin (Ins) gene mutation; ② formation of endogenous and exogenous Ins antigens, ③ Ins receptor antigen formation, ④ acceleration of Ins degradation, and ⑤ excessive Ins resisting hormones including glucocorticoid hormone, catecholamine, glucagon, free fatty acid, etc. The post receptor factors mainly contain ① receptor biosynthesis rate lowering induced reduction of receptor count, ② abnormal process of receptor inserting into cellular membrane, ③ reduction of receptor affinity with Ins, ④ acceleration of receptor degradation, and disturbance of receptor re utilization. The possible acupuncture target sites for bettering IR are ① lowering serum Ins level, ② raising C peptide/Ins, ③ increasing Ins resisting hormone content, and ④ elevating Ins sensitivity. The authors also put forward some suggestions about the research on mechanisms of acupuncture in relieving IR from pre receptor, receptor and post receptor levels.
摘要:为了解针灸治疗变态反应性鼻炎在临床中的进展情况 ,本文对近几年文献有关资料进行了归纳总结 ,从针刺、耳穴贴压、穴位注射、穴位贴敷及穴位综合疗法等不同方面分别阐述 ,可见选取不同的穴位、施以不同的疗法 ,均取得了较好的疗效。故以针灸治疗本病具有疗效肯定、副作用小的优点。本文还对今后的临床研究方向提出了建议In the present paper, the authors reviewed advances in the treatment of allergic rhinitis (AR) by acupuncture and moxibustion in recent years. In clinic, AR can be effectively treated using ①body acupuncture, ②ear acupuncture, ③acupoint injection, ④acupiont scrapping, ⑤comprehensive therapy of acupuncture, cupping and moxibustion, or acupuncture, scrapping and cupping, or ginger separated moxibustion and acupoint plaster of Chinese herbal medicines, or acupuncture and acupoint injection, and ⑥acupoint catgut embedding, simple cupping or acupoint ultrasonic radiation. Clinical practice indicated that satisfactory effects can often be achieved through selecting different acupionts according to syndrome differentiation or puncturing topical acupoints and acupuncture moxibustion (acumoxi) treatment of allergic rhinitis has the advantages of affirmative effect and less side effects. However, some problems as non united standards for evaluating the therapeutic effect, lack of reasonable control group, etc. still exist, hindering the development of acumoxi treatment of AR and the improvement of clinical therapeutic effect. This article also put forward some suggestions on the direction of clinical research in the future.
