Objective To determine the expression of glial fibrillary acidic protein(GFAP) and vascular endothelial growth factor(VEGF) in the hippocampus of rats with Alzheimer's disease(AD), and to determine the effect of butylphthalide on them and its significance. Methods Sixty male adult rats were randomly divided into a model group, a Butylphthalide group, and a control group. AD models were established by injecting β-amyloid protein 1-42 into the hippocampus of rats. Sixty days later,the rats were sacrificed and both sides of the hippocampus were sectioned for immunohistochemistry. Results Positive cells of GFAP in the hippocampus of the model group increased and the expression of VEGF decreased statistically, compared with the control group(P<0.01). The positive cells of GFAP in the hippocampus of the butylphthalide group decreased and the expression of VEGF increased significantly, compared with the model group(P<0.05). Conclusion Butylphthalide may protect the neuron-vascular unit of the hippocampus of Alzheimer model rats by inhibiting the expression of GFAP and increasing the expression of VEGF.

Two pairs of primers specific to small subunit ribosomal DNA of Plasmodium falciparum were designed and the expected SSUrDNA fragment was amplified for detecting P.falciparum infection with double-ternperature-nested polymerase chain reaction using DNA prepared by boiling method. The results showed that the nested PCR could amplify a constant size of desired SSUrDNA fragment of P. falciparum which was further confirmed by digestion of restrlction endonuclease and could detect parasitemia level of 0. 8 ? 10-6. It has great potentials for identifying Plasmodium species in ring form of erythrocytic stage and detecting mixed Plasmodium infections. Therefore, it is suggested that this method is sensitive, accurate, simple and rapid in detecting Plasmodium falciparum in blood samples for malaria diagnosis.

Objective To investigate the distribution of genotypes in chronic HBV infection (CHB) and acute HBV infection (AHB) patients in Shanghai. Methods Sixty-two patients with AHB and 73 patients with CHB admitted to ('hanghai Hospital of Shanghai between 2003 and 2007 were studied. Viral genotypes of all the patients were determined by direct gene sequencing.Meanwhile, epidemiological, clinical and biochemical parameters of all patients were collected. Mean values of different groups were compared by t test while frequency was compared by chi square test. Results The major prevalent genotypes in both AHB and CHB patients were genotype B and C (48.4% vs 51.6% in AHB patients and 26.0% vs 74.0% in CHB patients). The proportion of genotype B was higher in AHB patients compared to CHB patients (P= 0.02). Epidemiological factors and clinical outcomes were not statistically different among patients with different viral genotypes. The proportion of genotype C was much higher in CHB patients compared to AHB patients (P=0.006). The main transmission route of AHB was heterosexual interaction which was 18 out of 62 (29.0%), but in CHB patients, it was prenatal transmission which was 38 out of 73 (52.1%). Conclusions In shanghai, the main HBV genotypes in both AHB and CHB patients are genotype B and C. The proportion of genotype B is relatively high in AHB patients while proportion of genotype C is more common in CHB patients. There is no significant relationship between genotypes and the clinical outcomes of AI-IB patients.

Re-evaluation of bioequivalence of generic drugs is one of the key research focus currently. As a means to ensure consistency of the therapeutic effectiveness of drug products, clinical bioequivalence has been widely accepted as a gold standard test. In vitro dissolution testing based on the theory of the BCS is the best alternative to in vivo bioequivalence study. In this article, the conventional dissolution method and flow-through cell method were used to investigate the dissolution profiles of domestic amoxicillin capsules in different dissolution media, and the absorption behavior of the drugs with different release rates (t85% = 15-180 min) in the gastrointestinal tract was predicted by Gastro Plus. The flow-through cell method was thought better to reflect the release characteristics in vivo, and amoxicillin capsules with regard to the release rates up to 45 min (t85% = 45 min) were having a satisfied bioequivalence with the oral solution according to the C(max) and AUC. Although two different dissolution profiles of domestic amoxicillin capsules were found by flow-through cell methods, prediction results revealed that domestic capsules were probably bioequivalent to each other.

Objective To investigate the etiology and clinical characteristics of pediatric pulmonary arterial hypertension(PAH) and improve its early diagnosis and treatment.Methods The clinical and echocardiogram data of all inpatients with PAH in Pediatric Department of Peking University First Hospital between May 1995 and May 2007 were retrospectively analyzed for age,sex,etiology,symptoms and echocardiographic measurement of pulmonary artery pressure.Data were divided into groups according to different etiology and statistics.Pulmonary arterial systolic pressure(sPAP) values estimated from the tricuspid regurgitant velocity by Doppler echocardiography were compared among different groups.Cases who were not belonged to the first category of the Venice Clinical Classification of pulmonary hypertension were not included.Results Totally 276 cases,168 boys and 108 girls were diagnosed to have PAH.Age ranged from 1 month to 17 years,median age was 9 months.Most of pediatric PAH was associated-PAH(267 cases,96.7%),while idiopathic PAH took a small part(9 cases,3.3%).Congenital heart disease-associated PAH(CHD-PAH) was predominant(245 cases,88.7%) and left to right shunt was the main lesion (217 cases,88.6%),while complex lesion-associated PAH comprised 28 cases(11.4%).Connective tissue disease associated PAH(CTD-PAH) was the second common among this group of pediatric PAH patients(19 cases,6.9 %).The incidence of PAH in systemic lupus erythematosus(SLE),juvenile rheumatoid arteritis and takayasu arteritis were 10.3 %(13/126),8.7%(4/46),15.4%(2/13),respectively.The other 3 cases of PAH were associated with portal hypertension(2 cases) and thalassanemia(1 case).The estimated sPAP from tricuspid regurgitant velocity in 8 cases with idiopathic PAH[(74.6?23.9) mmHg(1 mmHg=0.133 kPa)]was higher significantly compared with those of 33 cases of CHD-PAH [(58.0?19.7) mmHg ] and 12 cases of CTD-PAH [(49.6?18.9) mmHg] respectively(t=-2.052,-2.609 Pa
