Objective To observe the effects of Astragalus Polysaccharide(ASP)and total glucosides of paeony(TGP)on lipid accumulation in THP-1 macrophage-derived foam cells.Methods The content of lipid accumulation in THP-1 macrophage-derived foam cells was measured through photoes under microscope and graph analysis software.Results In the culture medium without apoA-I,the content of lipid accumulation in the groups of ASP was increased significantly(P

Vascular cognitive impairment (VCI) is a cognitive impairment caused by cerebrovascular disease and its risk factors,its mechanism is very complex Recent studies have shown that cerebral microbleed (CMB) is correlated with VCI.This article reviews the relationship between CMB and VCI.

Objective To observe the curative effect of acupuncture on insulin receptor substrate 1 ( IRS-1) , IRS-2 and glucose transporter 4 (GLUT4) in skeletal muscle of experimental rats with insulin resistance (IR) . Methods Thirty-two rats were randomly divided into normal group, model group, acupuncture normal group and acupuncture model group. The fasting plasma glucose ( FPG) level was detected with glucose oxidase method, fasting insulin and C-peptide ( C-P) were examined with enzyme linked immunosorbent assay ( ELISA) , insulin sensitivity index ( ISI) was calculated, and IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of skeletal muscle were observed by real-time PCR-based fluorescent assay in each group. Results Compared to the normal group, the FPG, FINS, C-P levels were increased dramatically (P<0.01), ISI, IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of the model group declined remarkably ( P<0.01). Compared to the model group, the FPG, FINS, C-P levels declined evidently ( P<0.05 or P<0.01) , and ISI, IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of the acupuncture model group were increased dramatically ( P<0.01). Conclusion The curative mechanism of acupuncture for insulin resistance is probably related to the increase of IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA expression in skeletal muscle which contributes to the improvement of PI3K signal pathway.

Objective:To enhance the ability of organizing, commanding, decision-making and contingency-meeting of campaign medical support commanding officers so as to qualify them for their positions by simulation training. Methods: Based on the decision support theory, modern medical support theory, health service optimized decision support system and medical support command simulation training system, we designed and constructed a simulation training platform for medical support decision optimization. Results: A network-based simulation training platform was successfully constructed, which gives a strong support to the simulation training in medical support decision optimization under the network circumstance. Conclusion: The application of the simulation training platform has enriched the content and renewed the pattern of training in decision optimization for campaign medical support commanding officers.

Objective To set up a RP-HPLC method for determining gastrodin and ferulic acid in drug delivery system of Dachuanxiong simultaneously. Methods ODS-2 Hypersil column was used with methanol-1% glacial acetic acid as solution gradient elution. The flow rate was 1 mL/min and column temperature was 25 ℃. The wavelength of detector of gastrodin was 270 nm, and ferulic acid was 322 nm. Results Gastrodin and ferulic acid can be separated well with other components within 40 minutes. The linear range of gastrodin was 0.092～1.840 ?g (r =1.000 0), and ferulic acid was 0.122～2.440 ?g (r =1.000 0). The average recovery rate of gastrodin was 99.50% with RSD=1.23% (n =5), and ferulic acid was 101.5% with RSD=1.52% (n=5). Conclusion The method is simple, rapid, accurate and reliable, and can be used for determining gastrodin and ferulic acid in drug delivery system of Dachuanxiong simultaneously.

94 cases of pituitary adenomas were examined with radio immunoassay, immunohis-tochemical technique and electron microscopy. Among them, 36 cases associated with hypersomato-tropinemia and hyperprolactinemia were studied. The results showed that they could be classified into four types: (1) mixed growth hormone and prolactin cell adenomas; (2) acidophil stem cell adenomas; (3) plurihormonal adenomas; and (4) growth hormone adenmoas. The pathological and clinical characteristics were discussed.

Objective To explore the manifestation and diagnostic value of CT in retinoblastoma. Methods Twentythree cases of retinoblastomas proven by operation and pathologic examination were collected. Their CT images, clinical symptoms and pathologic results were retrospectively analyzed. Results Twentythree patients of retinoblastomas aged from 4 months to 9 years (mean 2.4 years). CT images showed soft tissue mass (shaped as node, crescentshaped or occupied the entire space of the eyeball) was in the globe of all cases. There was calcification in 19 cases (82.6%), including “small pinch” in 12 cases or “patches” in 7 cases. Five cases were found the optic nerve thickened (21.7%), and 1 case of intracranial invasion through the optic nerve canal (1/23), and 6 cases of retina detachment (6/23). The lesion showed mild or moderate enhancement after intravenous contrast medium were performed. Conclusion CT has an advantage on showing the size, shapes, intrastructures and invasive degree of the lesion, and is meaningful to the diagnosis and differential diagnosis of retinoblastoma.

Objective To compare the diagnostic values of the detection of urine exfoliated cells by FISH and cytology technolo‐gy in bladder urothelial tumor .Methods The combination probes of CSP3/CSP7 and GLPp16/CSP17 were both used in the FISH detection of urine exfoliated cells from suspected patients with bladder urothelial tumor .The urine exfoliated cells were detected by cytology technology at the same time .The sensitivity and the specificity of the two methods were compared .Results The sensitivi‐ty and specificity of FISH for bladder urothelial tumor screening were 92 .5% and 85 .0% respectively ,and those of cytology tech‐nology were 27 .5% and 90 .0% respectively .The sensitivity of FISH was significantly higher than that of cytology technology (P<0 .05) ,however ,the specificity differences between FISH and cytology technology were not statistically significant (P>0 .05) .Conclusion FISH is expected to become a new method for the screening of bladder urothelial tumor .
