Objective: To observe the effect of GETO on learning and memory of experiment AD model rats and search its cholinergic mechanism of action.Methods: ?-amyloid protein(A?_(1-42)) injection into hippocampus in rat was applied to make experimental rat model of AD.Morris water maze test were employed to investigate the function of learning and memory in AD model rats after 4 weeks,and immunohistochemical stain was done with Choline Acetyltransferase(ChAT) and nerve growth factor(NGF) antibodies after Morris water maze test,and system of image pro-plus were used to gain the number and grey degree of positive neurons.Results: In Morris water maze test: The mean escape latent period of the Model rats obviously prolonged than that of the Normal rats,the number of traversing flat roof obviously decreased.The mean escape latent period and the number of traversing flat roof of the GETO rats significantly shorten than the model rats.Immunohistochemical test: The number of positive staining neuron in hippocampus CA1 of ChAT and NGF in the GETO rats was not significantly different from those in the Normal rats and the Donepezil rats,but significantly different from those in Model rats with injection of A?_(1-42)(P

AIM: To determine the contents of baicalin, berberine, rhein in Yiqing Capsule(Radix et Rhizoma Rhei, Radix Scutellariae, Rhizoma Coptidis) by HPLC. METHODS: The HPLC system consisted of Kromasil C 18 column (150 mm?4.6 mm, 5 ?m), 0.02 mol?L -1 phosphoric acid (TEA adjusted to pH=6.82)-acetonitrile(40∶11) mixture as mobile phase, detection wavelength at 254 nm, flow rate of 1.0 mL?min -1. RESULTS: The calibration curves of three ingredients were linear within the range of 3.666-73.32 mg?L -1(r=0.9998, baicalin), 0.3112-15.56 mg?L -1(r=0.9998, rhein), 1.221-50.04 mg?L -1(r=0.9999,berberine), respectively. The average recovery of baicalin is 102.3%(RSD=2.5%), berberine for 101.8%(RSD=1.8%), and rhein for 98.3%(RSD=2.9%). CONCLUSIONS: The method is rapid, sensitive and accurate.

Objective To explore the diagnostic value of indirect magnetic resonance(MR) arthrography in detecting meniscus tears of the knees.Methods Routine plain MR of the knees followed by indirect MR arthrography was performed in 56 knees with suspected meniscal tears clinically.All cases had subsequently arthroscopic examination or operation.The sensitivity and diagnostic accordance of routine plain MR and indirect MR arthrography were compared based on the result of arthroscopic examination or operation. Results The signal intensity in the area of meniscal tears on image of indirect MR arthrography was obviously higher than that of routine plain MR.The diagnostic accordance rate of indirect MR arthrography was 78.67% while the routine plain MR was 52.20%,and the difference was statistically significant(?~2=21.066,P

Small cell lung cancer, most malignant and highly aggressive has a high relapse rate due to drug resistance. Potential strategies as high dose chemotherapy with autologous bone marrow transplantation and analysis on genes of metastases are focused on. In spite of great improvement, methods and clinic significances of bone marrow micrometastases are still to be determinated. Bone micrometastases may be a resort to clarify the mechanism of metastases.

Purpose To study immunohistochemical quality of prostatic basal cell(PBC). MethodsTherty-seven of basal cell of benign prostatic hypertrophy (BPH) were studied using routine HE stavningand En Vision immunohistochemical methods. Results The positive rate of 34βE12 in PBC were 100 %;but all of the PBC were negative with Vim and SMA; the positive expression of PsAP PSA in PBC were35% ;expression of ck in the PBC was 71% and the positive rate of S-100 in PBC was onty 13.5%.Conclusions The resuts suggest that high molecular weight keratin 34βE12 is a specific marker to PBC;PBC has ability to adenoid epithelia differentiation of prostate and hyperplasia itself. PBC play an importantrole in growth, hyperplasia and disease of prostate. The PBC unlike myoepithelia, the ability to myoepitheliadifferentiation is to go a step further controversial opinion.

Pseudomonas aeruginosa,a ubiquitous organism,shows a remarkable resistance to antibiotics because of its low permeability of the outer-membrane,over-expression of efflux pumps,inactivation of antibotics,or mutations in targets.These mechanisms are often present simultaneously,and increase the burden on clinical therapy.

Objective To investigate the effect of Brocho-Vaxom in curing chronic pulmonary heart disease and the influence of patient's immunity.Methods 58 patients with chronic pulmonary heart disease were randomly divided into two equal groups.Each patient of treatment group took a Brocho-Vaxom capsule(7mg/cap) every.The respiratory tract infection times and duration were observed.The serum IgA,IgG,IgM level were tested by fast immunonephelometry.The sub-type lymphocyte was tested by SP,and the NK cell's activity was tested by MTT.Results The infection time obviously declined in treatment group which the average was (2.5?1.8) in five months as compared with that in the controlled group(P

Objective To explore the pathogenic mechanism associated with insulin resistance(IR) and adiponetin(APN) abnormality in carotid atherosclerosis(CAS) patients complicated with nonalcoholic fatty liver disease(NAFLD),and to study their relationships with traditional Chinese medical(TCM) syndrome types.Methods Seventy-four CAS patients complicated with NAFLD(group A) and 25 CAS patients(group B) were enrolled into the study.Fasting blood glucose(FBG),fasting serum insulin(FI),and serum APN levels were measured.IR and APN were evaluated by the homeostasis assessment(HOMA) method.HOMA-IR and APN in group A were compared with those in group B,and bivariate correlation analysis was made between the two indexes in group A.The relationship of HOMA-IR and APN with TCM syndrome types was analyzed in group A.Results (1) HOMA-IR was obviously increased,and APN was obviously decreased in group A(P

Our study showed that the concentration of plasma ammonia in patients with hepatic encephalopathy was increased significantly than that in patients with decompensated liver cirrhosis, primary hepatocellular carcinoma and fulminant hepatitis. The concentration of serum free tryptophan and "free/total" tryptophan ratio in patients with hepatic encepha-lopathy were significantly increased as compared with patients of other three groups. The concentration of serum serotonin was not significantly increased and that of serum 5-hy- droxyindolacetic acid was significantly increased in comparison with normal controls. In addition, the concentrations of serum free tryptophan and serum "free/total" ratio were closely positive correlated with the degree of hepatic encephalopathy, the concentrations of. plasma ammonia and serum free tryptophan and serum "free/total" ratio were higher in patients with hepatic coma than that of patients regainning consciousness, but the difference was not statistically significant. The role of plasma ammonia and serum tryptophan in pathogenesis of hepatic encephalopathy was discussed
