[Objectives]This study was conducted to observe the mechanism of Dendrobium officinale Kimura et Migo on gastrocnemius muscle in rats with exercise-induced muscle damage(EIMD).[Methods]The micro-injury model of skeletal muscle was established by treadmill training.Forty two SD rats were randomly divided into a control group,1,12 and 24 h exercise groups,D.officinale 2 ml+1 h exercise group,D.officinale 2 ml+12 h exercise group,and D.officinale 2 ml+24 h exercise group,with 6 rats in each group.Various D.officinale groups were given the drug once in the morning and once in the evening at a dose of 2 ml/time,a week in advance.Except for the quiet group,the samples were collected from the 1,12 and 24 h exercise groups after anesthesia following 1,12 and 24 h of exercise for the last time,respectively,and the D.officinale 2 ml+1 h exercise group,D.officinale 2 ml+12 h exercise group and D.officinale 2 ml+24 h exercise group were also sampled after anesthesia following 1,12 and 24 h of exercise for the last time,respectively.The contents of ATP,CK-MM and CK in rat serum were determined by enzyme-linked immunosorbent assay(ELISA).The histopathological changes of gastrocnemius muscle were observed by HE staining.PCR and Western-blot detection were carried out to analyze the effects of D.officinale on IGF-1 mRNA and protein expression in gastrocnemius muscle.[Results]Compared with the quiet group,the ATP contents in the serum of rats in the 1,12 and 24 h exercise groups significantly decreased(P<0.01),while the CK and CK-MM contents significantly increased(P<0.01).The expression of IGF-1 mRNA and protein in the gastrocnemius muscle tissue significantly increased(P<0.01).Compared with the 1 h exercise group,the ATP content and IGF-1 protein expression in the gastrocnemius muscle tissue of the D.officinale liquid+1 h exercise group significantly increased(P<0.05),while the CK and CK-MM contents significantly decreased(P<0.01).Compared with the 12 h exercise group,the D.officinale liquid+12 h exercise group showed a significant increase in ATP content(P<0.01),significant increases in IGF-1 mRNA and protein expression in the gastrocnemius muscle tissue(P<0.01),and significant decreases in CK and CK-MM contents(P<0.01).Compared with the 24 h exercise group,the ATP content and IGF-1 mRNA and protein expression in the gastrocnemius muscle tissue of the D.officinale liquid+24 h exercise group significantly increased(P<0.01),while the CK and CK-MM contents significantly decreased(P<0.01).From the pathological tissue morphology of the gastrocnemius muscle in rats with EIMD treated with D.officinale,it could be concluded that the gastrocnemius muscle of each exercise group was significantly damaged,and the damage was significantly alleviated after administration of D.officinale liquid.[Conclusions]The effects and mechanism of D.officinale on prevention and treatment of EIMD in rats might be related to the promotion of IGF-1 mRNA and protein expression in injured tissues by reducing ATP energy consumption,CK-MM and CK activity. 展开更多

The effects of light on the quality and related genes of Dendrobium officinale were summarized, and the main chemical components and pharmacological effects of D. officinale were analyzed. The biomass accumulation of D. officinale is related to light quality and light intensity. Monochromatic light quality can make polysaccharide accumulate, and mixed light quality can promote cell proliferation and component accumulation of D. officinale. Under different light intensity, the polysaccharide content of D. officinale is different, and it changes with the change of light intensity. When a certain intensity is exceeded, the polysaccharide content decreases with the increase of light intensity. The chemical components of D. officinale are polysaccharides, alkaloids, amino acids, volatile components, etc. The analysis of the growth and components of D. officinale provides reference and basis for improving the quality and chemical components of D. officinale and promotes the research and development of related products of D. officinale. 展开更多

The Yunnan-Guangxi-Guizhou rocky desertified area in southwestern China is one of the contiguous extremely poor areas identified in the Outline of Poverty Alleviation and Development in the Rural Areas of China(2011-2020).In rocky desertified areas,due to long-term severe soil erosion,large areas of bedrock are exposed or gravels are accumulated.This bare rock and gravel-mulched land has become the main land type in the rocky mountains.Under normal circumstances,it cannot be directly used for agriculture,forestry,animal husbandry,and fishery production,and is classified as land that is difficult to be utilized.In recent years,in Debao County,Baise City,Guangxi Zhuang Autonomous Region,as a deeply impoverished county in the Yunnan-Guangxi-Guizhou rocky desertified area,a new land use model of karst rocky desertified land,that is,planting Dendrobium officinale Kimura et Migo on bare rocky ground,has emerged,and certain poverty alleviation benefits have been achieved initially.In this article,on the basis of analyzing the suitability of planting D.officinale Kimura et Migo on karst rocky desertified land,the practice of planning D.officinale Kimura et Migo on the rocky desertified land in Debao County was elucidated,and then suggestions for reasonable promotion of ecological planting of D.officinale Kimura et Migo in karst rocky desertified areas were put forward. 展开更多

[Objectives] To observe and compare the clinical effect and safety of Dendrobium officinale Kimura et Migo from Longhushan on treatment of type 2 diabetes. [Methods] 90 patients with type 2 diabetes were randomly divided into group A,group B and control group by randomized control method. Group A adopted D. officinale Kimura et Migo and metformin hydrochloride; group B adopted D. officinale Kimura et Migo; the control group adopted metformin hydrochloride. The fasting plasma glucose( FPG) of 3 groups was measured before the treatment and 2 weeks,4 weeks,6 weeks,8 weeks,10 weeks,and 12 weeks after the treatment,Hb A1 c was measured and diabetes symptom grade score was counted before the treatment and 12 weeks after treatment,observation indicators and clinical effect of 3 groups of patients were compared. [Results] The fasting plasma glucose level in group A was lower than that in other 2 groups,the difference was statistically significant( P < 0. 01),and there was no statistical significance in the difference between group B and the control group( P >0. 05); Hb A1 c of group A for 12 weeks after treatment was lower than that of other 2 groups,the difference was statistically significant( P < 0. 01),and there was no statistical significance in the difference between group B and the control group( P > 0. 05); the difference in diabetes symptom grade score of group A was greater than that in other 2 groups,the difference was statistically significant( P < 0. 01),and there was no statistical significance in the difference between group B and the control group( P > 0. 05). [Conclusions]D. officinale Kimura et Migo from Longhushan can effectively reduce the fasting plasma glucose level and Hb A1 c of type 2 diabetic patients and effectively improve the symptoms of patients; clinical application of D. officinale Kimura et Migo has equivalent effect with metformin hydrochloride,and combination of D. officinale Kimura et Migo with metformin hydrochloride has better effect than single use. 展开更多
