ABSTRACT
Objective To analyze the monosaccharide composition and the relative content of different alcohol precipitations of Panax japonicus polysaccharides.Methods The four components of Panax japonicus polysaccharides were isolated by stepwise ethanol precipitation method.The four components of Panax japonicus polysaccharides were hydrolyzed with trifluoroacetic acid (TFA) and derivated by l-phenyl-3-methyl-5-pyrazolo (PMP),respectively.The monosaccharide composition and relative content were analyzed using LC-FT-ICR-MS and HPLC-UV method.Results The four components of Panax japonicus polysaccharides consisted of glucose,rhamnose,galacturonic acid,galactose,arabinose,and glucose was the main monosaccharide.With the increase of ethanol concentration,the relative content of Ara increased gradually,as while the GalA decreased.Conclusions Precolumn derivation HPLC method was successfully applied for the determination of the monosaccharides in Panax japonicus polysaccharides,and there were differences in the four ethanol precipitations of Panax japonicus polysaccharides.The study can provide a basis for the separation of Panax japonicus polysaccharides.
ABSTRACT
At the present,systemic lupus erythematosus is a heterogeneous disease in which diagnosis,especially early diagnosis,is always rather difficult.Because of this,the systems of classification criteria for clinical diagnosis,which include recommendations of the American college of rheumatology and the systemic lupus international collaborating clinics,have been utilized since 1971.However,there is still no single biomarker that is pathognomonic for the disease.Currently,the diagnosis still requiresold-fashioned clinical acumen with the assistance of standardized clinical and laboratory criteria.In the light of the commentary,future research may lead us to define subtypes of lupus from a genomic and proteomic standpoint.
ABSTRACT
At present, central nervous system involvement is the most common in neuropsychiatric lupus.This article discus-ses the research status of central nervous system lupus in the past few years which include characteristics of clinical presentation, etio-pathological mechanism, neuroimaging diagnosis and therapeutic strategy.Actually, the advanced technology, especially neuroimmu-nology and neuroimaging, in combination with early diagnosis, effective assessment and treat to target strategy could decrease global disease activity, ameliorate quality of life and increase life expectancy.Furthermore, the prospective researches should be paid more attention in lupus registries, neuropsychiatric questionnaires, damage index and improvement of severe refractory cases in clinic.
ABSTRACT
In 1999, the nomenclature and case definitions for neuropsychiatric lupus syndromes were published by American College of Rheumatology (ACR), and the cognition of neuropsychiatric damage of systemic lupus erythematosus (SLE) was gradually unified and standardized. Lupus headache is an intractable problem in SLE, especially in SLE patients complicated with multiple organ injury. In general, vascular headache is common in most SLE patients, and a small number of SLE patients complicated with nervous headache are found in clinic. Moreover, its pathophysiological mechanism is far from being understood. Although early diagnosis is essential for good outcomes, the diagnosis method is rather confused in the world. There still exist some limitations in the proposal of clinical classification of headache from ACR and International Headache Society (IHS), and the proposal does not mention the classification of headache related to psychiatric damage. Current therapeutic regimens are almost exclusively based on empirical evidence. Treatment approaches include symptomatic treatment, immunosuppressive, anticoagulant and anti-aggregant therapies. It provides enormous and hopeful space in research of combined therapy strategy, especially in the field of traditional Chinese medicine. The authors discussed the relationship between lupus headache and headache due to internal injury in the view of integrated traditional Chinese and Western medicine, and suggested that the treatment strategy for lupus headache should be made in argument with the headache due to internal injury. Syndrome differentiation treatment according to deficiency in the root and excess in the branch and the therapy for activating blood to dredge collaterals maybe have great advantages in treatment of the headache in SLE.
ABSTRACT
Ischemic stroke is a critical society-medicine-economy problem,and effective therapy is rather insufficient.Nowadays,method of promoting blood circulation and removing blood stasis was popularly adopted,but only enjoyed limited curative effect in segmental stage of illness in patients.In this article,we analyzed and discussed mainly concept and viewpoint on blood stasis syndrome in Traditional Chinese Medicine,moreover,and provided advanced data for experimental and clinical research in the future.
ABSTRACT
This article discusses the status quo of the researches on neuropsychiatric lupus,including its pathophysiological mechanism,clinical manifestation,diagnosis,treatment and prognosis.Cerebrospinal fluid examination,electroencephalography and brain imaging could improve the sensitivity of the diagnosis of neuropsychiatric lupus.Aggressive immunosuppressive agents,high-dose corticosteroids and anticoagulants remain the key to the therapy.However,future researches should focus on the control of long-term relapse and the improvement of the quality of life.
ABSTRACT
Objective:To explore and discuss the effect of Xiaopi Yueyi formula on behavioral changes in rats with chronic fatigue syndrome.Methods:24 rats were divided into group model(16 rats) and control(8 rats) at random,and after produced rats with chronic fatigue syndrome,half in the former were taken orally with Xiaopi Yueyi formula while the latter were taken equally normal saline,moreover,methods of Open-Field、tail suspend time and exhaust swimming time were estimated and evaluated.Results:After succeeding in chronic fatigue manifestation in rats of group model,number of parallel and vertical movement diminished markedly,furthermore,time of tail suspend and exhaust swimming prolonged apparently.Nevertheless,Xiaopi Yueyi formula could ameliorate significantly these parameters in rats(P
