ABSTRACT
Objective:To observe the effect of Dredging Correcting Manipulation on cblC methylmalonic aciduria (MMA). Methods:From October, 2017 to October, 2018, 72 children with cblC MMA combined with growth retardation were divided into control group (n = 36) and experimental group (n = 36) according to the consent of their parents. The control group accepted routine medicine, and the experimental group received Dredging Correcting Manipulation in addition. The Griffiths Development Scale-Chinese version (GDS-C) was used to evaluate the two groups before and after treatment. At the same time, body length, body mass and head circumference were measured. Results:Six cases in the control group and five cases in the experimental group were dropped out. There was no significant difference in the development quotients of GDS-C in gross movement, personal and social, hearing and speech, hand-eye coordination, operation and total quotient between two groups before treatment (P > 0.05). After treatment, all the development quotients increased in both groups (t > 6.110, P < 0.001), and the development quotients of GDS-C in gross movement, personal and social, hand-eye coordination and total quotient were higher in the experimental group than in the control group (t > 2.154, P < 0.05), as well as the body length (t = 2.027, P < 0.05). Conclusion:Dredging Correcting Manipulation can promote the neuropsychological and physical development of children with cblC MMA combined with retardation.
ABSTRACT
Gentianae Radix et Rhizoma has a long history of medication,and was recorded in Shennong Bencaojing. Through the study of herbal medicine of Gentianae Radix et Rhizoma,we reviewed and analyzed previous herbal records,studied its basic,origin and processing methods, and provided the basis for further development and utilization of Gentianae Radix et Rhizoma. Through the analysis of ancient herbal researches and drawings,we knew that the ancient resources of this medicine were basically consistent with Gentiana scabra and G. manshurica. The Latin name of the original plant of gentian medicinal herbs set forth in the modern literature was analyzed for the first time. The commodities of this medicine were divided into Guanlongdan and Dianlongdan. Guanlongdan was produced in Northeast China, and consisted of G. scabra,G. manshurica,and G. triflora. Dianlongdan was G. rigescens and grew in Yunnan province. Due to various reasons, such as historical changes, genuine producing areas of medicinal materials gradually changed from Jiangsu and Zhejiang to Northeast China. The processing methods of Gentianae Radix et Rhizoma included preparing with wine, preparing with licorice juice and preparing with ginger juice. The purpose of these processing methods is to suppress its nature of bitter and cold. Among those processing methods,preparing with wine has the longest history, and can promote the dissolution of the active ingredients of gentian,thus is a better method of processing. This study provides the basis for radical reform, resource development, correct use, and determination of genuine producing area and processing methods for Gentianae Radix et Rhizoma.
ABSTRACT
By determination the section color and lustre indexes as well as the content of baicalin in 30 batches of Scutellariae Radix slices, calculate the correlation of these two, screen the color and lustre indexes which could represent their intrinsic quality, and establish a new grade classification method based on the results. The results showed that samples met the conditions of △L≥－37, △b≥45 simultaneously were picked grade and the content of baicalin was of ≥200 mg•g⁻¹ definitely; Samples inconsistent with any one of above conditions were general grade. This research indicated that indexes of △L and △b could characterize both the color and luster of slice and intrinsic quality, so that could be used as the indexes to classify the grades of Scutellariae Radix slices accurately, easily and objectively. The research results would provide new ideas and references for grade classification of traditional Chinese medicine slices.
ABSTRACT
OBJECTIVE: To determine the pectin content in Panax ginseng. METHODS: Soluble sugar was removed firstly, then pectinase was added for enzyniolysis, and 3, 5-dinitrosalicylic acid colorimetry was employed for determination of pectin. RESULTS: The optimal conditions of determination were as follows: 500 mg of Panax ginseng powder was extracted with 80% alcohol in water bath at 80°C, then filtrated, and the residue was enzymolyzed with pectinase of 1200 u at 50°C for 6 h in 50 mL of 0.1 mol · L-1 citric acid-sodium citrate buffer (pH 3.5). The galacturonic acid from degraded pectin in Panax ginseng was determined with 3, 5-dinitrosalieyfic acid colorimetry. CONCLUSION: This method has been proved to be convenient and accurate, which can be applied to the determination of pectin content in Panax ginseng.
