ABSTRACT
Objective Toinvestigate the metabolic characteristics of triglyceride (TG) in the plasma of rabbitswith steroid?induced osteonecrosis of the femoral head and the therapeutic effect of Gushiling Capsule. Methods Rabbit model of femoral head necrosis induced by hormone was established. The level of plasma TG was detected by HPLC/MS and the relationship between the changes of plasma TG level and local histomorphology of femoral head was analyzed. Results Compared with the normal control group, significant changes of plasma TG levels were observed in the model group, the traditional Chinese medicine group and the western medicine group at each time point (P<0.01). However, no significant difference was found between the traditional Chinese medicine group and the western medicine group. Compared with the model group, only a small amount of high signal joint imaging and central signal of the femoral head were found by the MRI examination in the traditional Chinese medicine group and the western medicine group. Pathology assay results showed the degree of femoral head osteonecrosis in the Chinese medicine group was milder than that in the Western medicine group. Conclusion Gushiling Capsule and western medicine Simvastatin have the similar effect of reducing plasma TG, which may be one of the mechanisms underlying Gushiling Capsule preventing steroid?induced femoral head necrosis.
ABSTRACT
Objective:To analyze the magnetic resonance imaging (MRI) features of parasellar cavernous haemangioma and improve the diagnosis and differential diagnosis accuracy.Methods:13 patients with parasellar cavernous haemangioma were collected.All the patients were diagnosed by MRI and confirmed by pathology.Based on the pathologic findings,the MRI features were discussed.Results:9 cases presented horizontal dumbbell.The lesions located in the parasellar were larger than the sella turcica.The main body position of the lesions were centered lateral to the parasellar and encasesed the intracavernous internal carotid artery (ICICA).While,1 cases were similar in size and shape.1 case was located in the sella turcica.2 cases was centered lateral to the ICICA.pituitary were detected obscurity in 7 cases and displaced in 6 cases,6 cases appeared extremely high homogeneous intensity on T2-weighted images:as bright as cerebrospinal fluid signal.Only 5 cases underwent three-dimensional arterial spin labelling perfusion imaging (3D-ASL).The lesions revealed marked hypoperfusion.The cases of misdiagnosis were 9,including 4 cpituitary adenomas and 5 meningiomas.Conclusions:The characteristics of MR images ofparasellar cavernous haemangioma were horizontal bottle gourd form,the main body position of the lesions were centered lateral to the parasellar and encasesed the (ICICA),and their extremely high homogeneous intensity on T2-weighted images:as bright as cerebrospinal fluid signal.In cases that are equivocal,3D-ASL were useful in differentiating cavernous haemangiomas from parasellar meningiomas,which could decrease mistaken diagnosis.Graspping the imaging feature and differential diagnosis were helpful for the diagnosis of this disease.
ABSTRACT
Objective To evaluate the effect of antler polypeptides from Cervus elaphus yarkandensis on MC3T3-E1 cells. Methods The concentration of antler polypeptides of Cervus elaphus yarkandensis was measured by BCA protein assay kit. MC3T3-E1 cells were cultured and analyzed by BCIP/NBT chromogenic alkaline phosphatase (ALP) staining kit. After being induced to form mineralized knot, the cells were stained by using Alizarin red staining. Three different concentrations (10, 1.0, 0.1 μg/mL) of antler polypeptides were analyzed by MTT method and micronutrients enzymes standard method to determine the effect of cell proliferation and ALP synthesis. Results The concentration of antler polypeptides was 0.07 mg/mL. The results of in vitro cell activity analysis showed that the positive rate of ALP was 90%and the mineralization knot was stained red. Compared with the control group, the different concentrations of antler polypeptides all showed the function of cell proliferation and the effect was dose-dependent after 3 d and 7 d. Compared with the control group, at the 3 d, three groups of antler polypeptides promoted synthesis and secretion of ALP (P<0.01) and the results showed a dose-dependent effect. Conclusion Antler polypeptides could obviously promote the proliferation of MC3T3-E1 cells and secretion of ALP, which indicated that antler polypeptides have certain effect on osteoporosis.
ABSTRACT
OBJECTIVE:To observe the clinical efficacy of Tanreqing injection in the treatment of children's viral pneumonia.METHODS:A total of sixty children with viral pneumonia were randomly divided into 2 groups:the treatment group(n=30)were treated with Tanreqing injection(20mL)plus Glucose(250mL)qd for 7d while the control group(n=30)with Cibavirin(10～15mg?kg-1)plus Glucose(250mL)bid for 7d.The primary outcome measures were clinical efficacy and adverse drug effects(ADRs).RESULTS:The effective rate was 100% in the treatment group as compared with 80% in the control group,showing significant differences between the two groups(P
ABSTRACT
Objective To know the situation of smoking control in all kinds of restaurants and the attitudes of citizens toward it.Methods Using methods of spot field investigation and questionnaire survey,193 of restaurant staff and 189 customers in 353 restaurants & bars were investigated.Results The average ratio of smoking control of all sorts of restaurants and bars was both about 25%,and in west restaurants,the average ratio of smoking control was 39.2%.Both the customers and the restaurants keepers were consistent on smoking control;the average supporting rate was 72.1%.Conclusion With the opportunity of Beijing 2008 Olympic Games,It is urgent for us to expand propaganda against smoking,and to strengthen non-smoking legislation and make out feasible smoking control measures for this city.
ABSTRACT
Based on the point of view that the human body is an organic whole and the fact that virus and body is a unity of contradiction,the interaction mechanism of virus and immunity in the research of the anti-HIV/AIDS Chinese materia medica is discussed.On the one hand,it can widen our thinking to find new target of anti-virus drugs.On the other hand,it can also provide scientific support for understanding the complex mechanics of the anti-HIV/AIDS Chinese materia medica.
