BACKGROUND: NOV protein encoded by nephroblastoma overexpression gene(NOV) is IGF(insulin-like growth factor) -binding protein. What is its impact on human neural stem cell(hNSC) proliferation and differentiation?OBJECTIVE: To investigate the impacts of NOV protein on hNSCs proliferation and differentiation.DESIGN: A single factor analysis of variance experimental study using cells as subjectsSETTING: Department of histology and embryology, and department of neurobiology in a military medical university.MATERIALS: Study was conducted in the Department of Histology and Embryology of the Third Military Medical University of Chinese PLA. Subjects were hNSCs cultured from 10 to 14 weeks human embryo cerebral cortex.INTERVENTIONS: COS-7 cells were transfected by NOV gene recombined plasmid. COS-7 cell and COS-7 cell modified by NOV gene conditioned culture media(COS-CM and NOV-CM) were collected and reacted with the cultured HNSCs.MAIN OUTCOME MEASURES: hNSCs proliferation was detected by 3H-TdR scintillation analysis, and hNSCs differentiation was detected by immunocytochemistry and flow cytometer(FCM).RESULTS: Both COS-CM and NOV-CM could significant promote the intake of 3H-TdR by HNSCs, of which the 1/minute of NOV-CM group was significantly higher than that of COS-CM group(P < 0.05), which indicated that NOV-CM contained component that could facilitate hNSCs proliferation, and moreover, there was certain dose-effect relationship in NOV-CM' s facilitation of cellular proliferation. The results of immunocytochemistry and FCM revealed that there were more NF-200 positive cells in NOV-CM group, while many glial fibrillary acidic protein positive cells could be seen in COS-CM group.CONCLUSION: NOV protein might have facilitative effects on hNSCs proliferation and differentiation into neurons.

The cholesterol esterase and its oxidase were respectively immobilized onto sol-gel(tetraethyl orthosilicate)and then an enzymatic reaction column was prepared. Hydrolysis of cholesterol ester took place in the presence of cholesterol esterase to form cholesterol under catalysis of cholesterol oxidase, and Cholesterol was oxidized to produce hydrogen peroxide which reacted with luminal in the presence of simulated enzyme hemoglobin to result in the emission of light. Thereupon, a chemiluminescence system combined with flow injection technology by sol-gel immobilized enzyme was developed for the determination of cholesterol including free and total amount in human serum. The CL intensity was well linear with the concentration of cholesterol;liner range of total and free cholesterol was 1.01×10~(-6)~2.02×10~(-4) mol/L with a detection limit of 7.5×10~(-7) mol/L) and 5.0×10~(-8)~2.18×10~(-5) mol/L) with a detection limit of 5.0×10~(-9) mol/L respectively. Contrasted the method) with the biochemical analyzer (TBA-120FR), both the methods had no significant difference. This method has been successfully applied for the detection of cholesterol in clinic serum samples.

To examine the effect of Gankang Suppository on duck hepatitis B virus (DHBV), the serum biochemistry and hepatic histology in an animal model of DHBV infection, a model of DHBV infection was established by infecting 1-day-old Yingtaogu ducklings with DHBV-positive serum. The successful model was confirmed by PCR assay and 48 ducklings infected with DHBV were randomly divided into 3 groups: a Gankang Suppository treatment group, an acyclovir (ACV) group and a DHBV model group (control), with each group having 16 animals. All the animals were given the medicines for 4 weeks in a row. The serum of the animals was taken 14 and 28 days after the medication and 7 days after drug discontinuation. Real-time PCR was performed to detect the copy numbers of DHBV DNA in the serum. ALT and AST were dynamically monitored. The ducklings were sacrificed on the 7th day after the discontinuation of the treatment and livers were harvested and examined for inflammation and degeneration of liver cells by using HE staining. The results showed that on day 14, 28 after the treatment and day 7 after the withdrawal, the logarithmic values (log) of DHBV DNA copy numbers in ducklings of Gankang Suppository treatment group were significantly lower than that before the treatment (P=0.0092, P=0.0070, P=0.0080, respectively). Compared with DHBV model control group, the ALT level was significantly decreased (P=0.0020, P=0.0019, respectively) on day 28 after the treatment and on day 7 after the withdrawal. The AST level was also reduced on day 14 after the treatment (P=0.0298). Compared with the ACV control group, the level of ALT was lower on day 7 after the withdrawal (P=0.0016). Histologically, the hepatocyte swelling, vacuolous degeneration and acidophilic degeneration in Gankang Suppository treatment group were alleviated 7 days after the withdrawal as compared with model control group (P=0.0282, P=0.0084, P=0.0195, respectively). It is concluded that Gankang Suppository can effectively suppress DHBV replication, reduce the levels of serum ALT and AST and improve hepatic histology.

Objective To evaluate the diagnostic value of the aldosterone-renin ratio (ARR) for primary aldosteronism (PA). Methods Serum aldosteronos ( ALD ) and plasma renin activities (PRA)among 44 subjects with primary aldosteronism, 9 subjects with phecchromocytoma, 8 subjects with nonfunctional adrenal tumors, 12 subjects with Cushing syndrome, 4 subjects with stenosis of renal artery and 13 subjects with primary hypertension were retrospectively reviewed. ARR was calculated. The receiver operating characteristics (ROC) curves for every index were used to evaluate diagnostic value. Results The area under the curve(AUC) in the ROC curve of ALD in a supine position was 0. 947, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ALD in upright position was 0. 889, the cut-off value of ALD diagnosis of PA. The AUC for the ROC curve of ARR in a supine position was 0. 978, the cut-off value of diagnosis of PA. The AUC for the ROC curve of ARR in upright position was 0. 981, the cut-off value of specificity. If ARR was combined with ALD in upright position was used, the diagnostic value was better than either index. When ALD > 275 ng/L and the AUC for the ROC curve in upright position was 0. 989,specificity. Conclusions The diagnostic value of ARR in diagnosis of primary aldosteronism is higher than ALD and PRA. ARR in upright position is better than that in supine position, especially when combined with ALD > 275 ng/L in upright position.
