AIM: To study the difference in glucose and lactate levels between brain extracellular fluid (ECF) and plasma in rabbits in the different blood glucose levels. METHODS: Using intracerebral microdialysis technology, brain ECF levels of glucose and lactate were measured in every 10 min under basal conditions and during a hyperglycemia-hypoglycemia clamp study. RESULTS: Under basal condition, brain ECF glucose levels were markedly lower than ambient plasma levels (30% of plasma), whereas ECF lactate levels were substantially higher (165% of plasma). During the hyperglycemia-hypoglycemia clamps, the relationship between plasma and ECF levels of glucose remained similar, but changes in ECF glucose lagged about 30 min. There were no substantially changes in ECF levels of lactate during dynamical study. CONCLUSION: There are striking differences in glucose and lactate levels between brain ECF and plasma. Lactate may involve in the metabolic process of central nervous system.

Objective To study the relationship between the stenosis content of carotid artery and the degree of homocysteine (Hcy) by analyzing the level changes of Hcy in ischemic stroke patients.Methods One hundred and thirty patients of carotid artery stenosis with ischemic stroke were divided into four groups based on the degrees of carotid artery stenosis determined by ultrasound Doppler flow imaging:the slight stenosis group (32patients),the moderate group (35 patients),the severe group (33 patients) and the total occlusion group (30 patients).Meanwhile,30 healthy people were chosen as the control group.The levels of serum homocysteine (Hcy),total cholesterol (TC),triglyceride (TG) and low density lipoprotein (LDL) of each group were measured,and the results were compared with those of the control group.Results It was found that the serum Hcy level in ischemic stroke group were significantly higher than that in the control group (P＜0.05),whereas the variations ofTC,TG,HDL and LDL levels between the ischemic stroke group and the control group could be neglected (P＞0.05).An obviously increased order of serum Hcy levels was observed as the following,the control group,the slight stenosis group,the moderate group,the severe group as well as the total occlusion group.The difference between every two groups was statistically significant (P＜0.05).The level of serum Hcy was positive correlated to the content of carotid artery stenosis (r=0.835,P＜0.05).However,no correlation was found between the carotid artery stenosis and each level of TC,TG and LDL (r=0.031,0.012,0.018,respectively,P＞0.05).Conclusions The serum Hcy level is closely related to the degree of carotid artery stenosis,and high level Hcy is suggested to be one of major risk factors for ischemic stroke.

By means of joint research of new advanced technology project,joint development and application of appropriate health technology project,comprehensive prevention and control of chronic diseases between municipal hospitals and community clinics project and research supporting platform project,Shanghai Hospital Development Center has effectively improved the clinical science and technology innovation capability, promoted the development of medical disciplines and talents and improved the discipline influence of such hospitals.

This study aims to establish a new method for quality evaluation of Gentianae Macrophyllae Radix by simultaneous determination of five iridoids (loganic acid, 6'-O-beta-D-glucopyranosylgentiopicroside, swertiamarin, gentiopicroside, sweroside), and to detect five iridoids in the root of eight species (Gentiana macrophylla, G. straminea, G. crassicaulis, G. dahurica, G. robusta, G. waltonii, G. lhassica, and G. tibetica). The separation was carried out on a Shiseido SPOLAR C18 (4.6 mm x 250 mm, 5 microm) column eluted with mobile phase of water containing 0.04% formic acid (A) and acetonitrile (B) in a gradient program. The flow rate was 0.8 mL x min(-1). The detect wavelength was set at 240 nm. The column temperature was kept at 30 degrees C. The volume of injection was 5 microL. The five iridoids were well separated with ideal linear correlations. The average recoveries were 97.35% - 106.23%. All the five iridoids were detected in the root of eight species. The contents of same species changed in a somewhat wider range. The contents in root of G. dahurica were lower than that in other species.

Aim To explore the effect of genetic poly-morphisms of POR on the stable warfarin maintenance doses in Han Chinese patients receiving mechanical heart valve replacement. Methods The association between POR gene polymorphisms and warfarin doses of 185 Han Chinese patients were investigated through ANOVA or t test. SNPs of POR and VKORC1 were de-tected by Sequenom? DNA MassArray genotyping method. CYP2C9*3 was genotyped by polymerase chain reaction-restriction fragment length polymorphism method ( PCR-RFLP ) . Patients ’ clinical characteris-tics, INR value and daily dose were obtained from their medical records. Statistical analysis was performed by SPSS 21. 0 software. Results No mutant carriers of POR rs17148944 , POR rs56256515 and rs72553971 were found in this study. The genotype frequencies of other SNPs were in accordance with Hardy-Weinberg e-quilibrium. In the group of patients with CYP2C9*1*1 , the mutant type carriers ( T carriers ) of POR rs17685 had a significantly higher dose than CC carri-ers(3. 50 ± 1. 07) mg·d-1 vs (3. 14 ± 0. 94) mg· d-1,P =0. 03. Also, in the group of patients with CYP2 C9*1*1 and VKORC1 rs9934438 G allele carri-ers, the mutant type carriers ( T carriers ) of POR rs17685 had a significantly higher dose than CC carri-ers(4. 76 ± 0. 90) mg·d-1 vs (4. 08 ± 1. 03) mg· d-1 ,P=0. 04. No significant difference was found in different genotypes of POR rs2868177 . Conclusion These results illustrate that POR rs17685 T carrier is closely associated with a higher warfarin maintenance dose, suggesting that this SNP is useful for clinical guidance of warfarin.

Objective To study the characteristics of skinfold thickness of Han adults in Jiangsu province . Methods The skinfold thicknesses of facial , subscapular , suprailiac , biceps , triceps and calf on 311 urban adults ( 157 males and 154 females) and 421 rural adults ( 213 males and 208 females ) of Han were investigated in Huaian city of Jiangsu province .Results The thickness of skinfold of urban females were thicker than that of urban males .Rural adults were the same .Han adults of Jiangsu showed the most significant differences between urban areas and rural areas .The values of six skinfold thicknesses of Jiangsu urban adults have positive correlation with age .Conclusion Han adults of Jiangsu show the most significant differences between genders .

After more than3 years of pilot (since 2010), standardized training of resident physicians in Shanghai has made great progress, however, it still needs to be improved. Cerebral and spinal vascular diseases are main types of neurological diseases and they seriously influence people's life and health. Interventional neuroradiology plays an important role in the diagnosis and treatment of cerebral and spinal vascular diseases. However, in the current residency training system in Shanghai or other provinces of China, the training of interventional neuroradiology is not included. In this paper, the authors analyzed the important role of interventional neuroradiology in diagnosis and treatment of cerebral and spinal vascular disorders and discussed the feasibility, method, and time arrangement of including interventional neuroradiology curriculum into the schedule of neurology standardizedresidency training and hoped to provide reference for the relevant departments to formulate a future policy.
