[Clinical efficacy of fire needling combined with cupping therapy on herpes zoster of acute stage and the effect on Th17/Treg cellular immune balance].

OBJECTIVE: To compare the clinical efficacy between the combined therapy of fire needling and cupping, and western medication on herpes zoster of acute stage, as well as the effects on Th17 and Treg cells and inflammatory factors, i.e. IL-10 and IL-17 in the peripheral blood. METHODS: Eighty patients with herpes zoster of acute stage were randomly divided into a combined therapy (fire needling plus cupping) group and a western medication group, 40 cases in each one. In the combined therapy group, the pricking and scattering techniques with fire needle were used at ashi points and Jiaji (EX-B 2) corresponding to the affected spinal segments; afterwards, cupping therapy was delivered. The combined treatment was given once daily. In the western medication group, valaciclovir hydrochloride tablet and vitamin B1 tablet were administered orally. The duration of treatment in each group was 10 days. Before each treatment from day 1 to day 10 and on day 11 , the score of symptoms and physical signs was observed in the two groups separately. Before each treatment from day 1 to day 10 and on day 11, 30, 60, the score of visual analogue scale (VAS) and skin lesion indexes were observed in the two groups. On day 60, the incidence of postherpetic neuralgia was recorded in the two groups. The levels of Th17 and Treg cells, Th17/Treg ratio in the peripheral blood, as well as serum levels of IL-10 and IL-17 were detected before and after treatment in the two groups. The clinical efficacy was compared between the two groups. RESULTS: From day 6 to day 10 during treatment and on day 11, the scores of symptoms and physical signs in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 3, day 6 to day 10 during treatment and day 11, day 30, VAS scores in the combined therapy group were lower than those of the western medication group (P<0.05, P<0.01). On day 60, the incidence of postherpetic neuralgia in the combined therapy group was lower compared with that in the western medication group (P<0.05). The blister arresting time and scabbing time in the combined therapy group were shorter than those of the western medication group (P<0.05). After treatment, the level of Th17, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 were all lower in comparison with those in the western medication group (P<0.05). The curative and remarkably effective rate was 82.5% (33/40) in the combined therapy group, higher than 62.5% (25/40) in the western medication group (P<0.05). CONCLUSION: The early application of fire needling combined with cupping therapy can effectively treat herpes zoster of acute stage, relieve pain, and reduce the incidence of postherpetic neuralgia, which may be related to reducing the levels of Th17 and Treg cells, and Th17/Treg ratio in the peripheral blood, as well as the serum levels of IL-10 and IL-17 so that the cellular immune balance is modulated.

[Professor LIN Guo-hua's experience in treatment of progressive muscular dystrophy with acupuncture].

Professor LIN Guo-hua's experience is introduced in treatment of progressive muscular dystrophy with acupuncture. It is believed that the pathogenesis of this disease is related to spleen and kidney deficiency, qi and blood insufficiency and malnutrition of tendon and muscle. The treatment is determined in terms of the pathogenesis and focuses on the regulation of spleen and kidney functions. The thinking of treatment is summarized as exerting the strong stimulation of acupuncture specially at the acupoints on the head, supplementing the sea of marrow, adjusting simultaneously the three yang meridians, rather than treating particularly yangming meridian and regulating qi in priority and considering the lung function for wei (flaccid) syndrome. Moreover, in clinical treatment, the acupoint thread-embedding therapy is commonly combined to ensure the significant therapeutic effect.

[Effect of artemisinin on ischemia/reperfusion injury of isolated rat myocardium].

OBJECTIVE: To observe the effect of artemisinin on the ischemia/reperfusion injury of the iisolated rat myocardium and to preliminarily study the possible mechanism. METHOD: Fifty Wistar rats were randomly divided into 5 groups: a control group, an ischemia/reperfusion (I/R) group, and 3 artemisinin (AS) groups (10, 100, 1000 micromol x L(-1)), 10 rats in each group. Ischemia/reperfusion injury of the isolated rat myocardium was induced by a Langendorff system. The electrocardiogram, the cardiac functional parameters, coronary flow, and the activities of LDH (lactate dehydrogenase), CPK (creatine phosphokinase), SOD (superoxide dis-mutase) and the level of malondiadehyde (MDA) in myocardial tissue, and the myocardial ultrastructures were investigated. RESULT: AS (10,100 micromol x L(-1)) could significantly improve the index of the myocardial function (+/- dp/dt(max), LVSP) after the ischemia/reperfusion, increase the coronary flow, decrease the leakage of LDH and CPK, and increase the SOD activity and decrease the MDA level in cardiac tissues, and alleviate the myocardial ultrastructure injury. But, AS (1000 micromo x L(-1)) did not have the above effects. CONCLUSION: AS (10, 100 micromol x L(-1)) alleviate the myocardial ischemia/reperfusion injury in rats. The mechanism may be related to its functions of antioxidation and scavenging free radicals.

[Effects of resveratrol on isolated thoracic aorta rings of rats].

OBJECTIVE: To investigate the relaxative characteristics of resveratrol on thoracic aortic artery in the rat and its mechanism. METHOD: We perfused the isolated rings and observed the response of NA-induced artery contraction to resveratrol under the Ca2+-contained and Ca2+-free bath solutions. In the same way were the effect of reveratrol on the vascular smooth muscle observed by adding two different concentration of KCl (30 and 80 mmol x L(-1)), and the effect on the contraction of the vascular smooth muscle depending on the intracellular calcium and extracellular calcium were also observed by adding NA. We also observed the effect of resveratrol on the contraction of rings induced by NA in the presence of L-NNA and Glibenclamide. RESULT: Resveratrol relaxed rat aorta rings precontracted by NA in a dose-dependent manner. The relaxant effect of resveratrol on the rat rings of endothelium-denuded group was reduced compared with that of endothelium-intact group; the relaxant effect of resveratrol on rat rings was higher under the condition of Ca2+-free bath solution than that under the condition of Ca2+-contained bath solution. Resveratrol had a repressive effect on the aorta's contraction induced by intracellular calcium, but had no effect induced by extracellular calcium. Resveratrol relaxed the contractions induced by KCl 30 mmol x L(-1) as well as KCl 80 mmol x L(-1), but the contraction curve of KCl 80 mmol x L(-1) was shifted upward significantly. In the L-NNA group, the relaxant effect was attenuated by (26.0 +/- 4.6) %; but there was no change in the group of Glibenclamide ( P > 0.05). CONCLUSION: The results indicate that resveratrol relaxes vascular smooth muscle in an endothelium dependent manner. The mechanisms for this phenomenon seem to be related with promoting synthesis and release of NO, opening Ca2+ activated K+ channel (KCa channel) as well as the inhibition of Ca2+ influx and release of Ca2+ from intracellular stores.
