ABSTRACT
OBJECTIVE:To provide reference for standardizing the names of TCM from Rumex. METHODS:According to lit-erature research,the most frequently used names (such as Jinbuhuan,Tudahuang,Yangti) of TCM in Rumex were combed,and suggestions for existing problems were put forward. RESULTS & CONCLUSIONS:The TCM names were used confusedly,main-ly showing that inconsistent names of TCM from the same plant in different areas,same name of TCM from different plants in the same area,same name of TCM from different plants in different areas. The key to solving the confused use of names of TCM in Rumex is standardization and unification of medicinal plant source and names. It can be developed and solved in order by resource investigation and identification,establishing quality standard and excavating medicinal value,in which,conducting the resource in-vestigation and specie identification,determining the medicinal names,stipulating the official names and establishing the quality standard are the important work in future.
ABSTRACT
Rhizoma Pinelliae Fermentata(RPF)wasoneofthecommonlyusedChinesemateriamedica(CMM). According to the ancient and modern literatures on RPF, the historical evolution, fermentation methods, chemical compositions, efficacy and microbes of RPF were systematically summarized in this paper. Through the analysis on existing problems of fermentation strains, effective components, quality standard and fermentation process, the corresponding solutions were proposed. This work may provide an idea and reference for the further study of RPF.
ABSTRACT
This study was aimed to establish a rapid discrimination method of Pinellia ternataand its adulterants based on the odour fingerprints analysis.Typhonium flagelliforme and Arisaema Rhizome,which were the common adulterants of Pinellia ternata,were collected.The adulterants were mixed with Pinellia ternatain different proportions.E-nose technology was used to obtain the odour fingerprints of Pinellia ternataand its adulterants of different types and proportions.Chemometrics methods,such as the analysis of variance (ANOVA),principal component analysis (PCA) and discriminant factor analysis (DFA) were used in the analysis and discrimination on sensors response data collected by sensors.The results showed that there were obvious differences on the odour characteristics between Pinellia ternateand its adulterants.PCA can obviously discriminate Pinellia ternateand its adulterants.And the odour difference became obvious along with the increasing of the adulteration proportion.There was a linear relationship between e-nose signal and the proportion of Typhonium flagelliforme.The cumulative proportion in ANOVA of the DFA model was 100%.The correct recognition rate was not less than 97%.It was concluded that e-nose can be used for rapid discrimination of Pinellia ternataand its adulterants.This study provided new technology and method for the discrimination of adulterants of Chinese materia medica.
ABSTRACT
Odor and taste are characteristic properties of traditional Chinese medicine (TCM). They are closely related to the chemical compositions in TCM. They are also the outer reflection of TCM quality and an important part of the character identification. This article reviewed the current research on odor and taste identification of TCM, which indicated that odor and taste identification had not been paid enough attention to and its research lagged behind modern social development. Based on current analytical techniques and methods, this article proposed a new idea for odor and taste identification of TCM. The idea emphasized the objectification of odor and taste and TCM identification research should be combined with chemical components analysis.
ABSTRACT
Leukemia is the second most malignant tumor in children. The chemotherapy induced anemia [CIA] and hemorrhage are the most popular side-effects due to the myelosuppression of chemotherapy. So far, multitransfusion is still the timely and effective measure in curing these complications. The acquisition of human immunodeficiency virus [HIV] infection and subsequent development of acquired immune deficiency syndrome [AIDS] by component transfusion from donors at risk is well known, and prognosis of HIV infection is particularly severe in patients with leukemia. We report two leukemic cases that were infected with HIV through transfusion. The first patient was totally transfused with 16 U RBC, 20 U platelets and 820 ml fresh frozen plasma, and later test showed that his first used FFP carried the HIV. For the second 2 U RBC, 5 U platelets and 1500 ml fresh frozen plasma were transfused to her. Late test of her used blood products showed that the fourth RBC carried the HIV. Both results were confirmed by the local Center for Disease Control [CDC]. They were not transfused before the diagnosis of leukemia. Their parents were healthy with negative HIV-Ab. Since the two leukemic patients suffered transfusion-associated HIV with poor prognosis, we must take more efforts to utilize blood products judiciously, manage blood donors, test blood samples etiologically, shorten HIV testing "window periods" and preventive vaccination against HIV to reduce the incidence as low as possible
