ABSTRACT
Objective To observe the expressions of CD26, Ki67 and epidermal growth factor receptor(EGFR) proteins in thyroid neoplasms, to explore their value in differential diagnosis between benign and malignant thyroid neoplasms and to search for molecular marker in well-differentiated thyroid carcinomas.Methods The expressions of CD26,Ki67and EGFR proteins were examined by immunohistochemistry in 50 differentiated thyroid carcinomas (TC) and 50 thyroid adenomas (TA) and their relationships were analyzed.Results The positive rate and expression intensity of CD26,Ki67and EGFR proteins in TC were significantly higher than those in TA, and especially higher in follicular TC than those in follicular TA.Conclusion The abnormal expressions of CD26, Ki67and EGFR proteins appear to be valuable in differential diagnosis and predicting prognosis of thyroid carcinomas, especially CD26 can be used as a diagnostic marker in well-differentiated carcinoma of follicular cell origin.
ABSTRACT
Objective:To collect and evaluate the information of literature on perimenopausal syndrome.Methods:The computer retrieval method supplemented by manual inspection of literature.Results:590 relevant documents were retrieved and among which 129 were comprehensively studied.Conclusion:The quality of the literature should be improved though there was an annual quantitive increase of the literature on perimenopausal syndrome in TCM.Great efforts should be made in this aspect.
ABSTRACT
Objective:To observe the effect of Weijinkang Oral Liquid on rats'models with siliconic nodules and the diffuse fibrosis of the lungs.Methods:45 rats were randomly divided into the blank group,dust-affected group,and treatment group.The rats in the blank group were fed in normal environment.The rats in the dust-affected group were given regular feed.The dust-affected rats in the treatment group were administrated 1.0mL/100g of Weijinkang condensed liquid in 30% by stomach perfusion,two times daily(33 times of human's dosage).Five of each group were killed and anatomized in turn on the 15th day,the 30th and the 90th day.Results:On the 90th day the pathological test showed massive cartilaginous changes projecting to the pulmonary surface in the dust-affected group.There was no abnormality of lungs in both treatment group and blank group.After receiving Weijinkang Oral Liquid the rats in the treatment group showed greater weights than those in the dust-affected group,and the weights of fresh and dehydrated lungs were lighter than those in dust-affected group.Conclusion:Weijinkang Oral Liquid had certain effect on siliconic nodules and the diffuse fibrosis of the lungs caused by pneumonoconiosis.
ABSTRACT
Objective:To investigate the protective effects and mechanism of ligustrazine on myocardial ischemia reperfusion injury(MIRI) in rats.Methods:30 Wistar rats were divided into three groups randomly:sham operation group,ischemia reperfusion injury group(IR),and ligustrazine preconditioning group(LI).The model of MIRI was produced,Immunohistochemical S-P method was used to detect the expressions of HSP25 and p38MAPK proteins in MIRI tissues.Results:Compared with IR group,the expression of HSP25 protein in LI group increased significantly(P
ABSTRACT
ZHAO Bing-nan is a famous doctor in treating dermatogic disease.He is good at harmonizing yin and yang when he treats dermatogic disease.The basic Chinese materia medica he commonly used are: Dutchmanspipe Vine,Suberect Spatholobus,Tuber Fleeceflower Stem and Gambir Plant.Except application of promoting blood circulation for removing blood stasis,he also gives consideration to excessiveness of heart and liver fire,syndrome of damp disturbing spleen.He creats sevel curative methods,such as clearing liver and purging gallbladder,clearing heart fire,dispelling wind and removing dampness.He also creats ‘San Xin Fang’(Lotus Plumule,Weeping Forsythia Capsule Plumule,gardenia).The methods of treatment and prescriptions used by ZHAO Bing-nan have a good effect in treating acute inflammatory dermatogic disease(in excessive heat stage),for example,acute eczema,acute dermatitis,herpes zoster,sensitization dermatitis,drug eruption.
