Objective To observe the effect of electroacupuncture on hand dysfunction after stroke. Methods Forty hemiplegic patients after stroke were selected from a multi-center large-scale trail, belonged to rehabilitation group (n=20) and electroacupuncture group (n=20), who accepted routine rehabilitation and additional electroacupuncture, respectively, for six weeks. They were assessed with Brunnstrom Grade, Fugl-Meyer Assessment (FMA), Wolf Motor Function Test (WMFT) and modified Barthel index (MBI) before treatment, two, four and six weeks during treatment, and twelve weeks after treatment. Results There were differences between two groups in scores of FMA, WMFT and total time to complete WMFT twelve weeks after treatment (t>1.900, P<0.05). There was no difference between two groups in scores of MBI and Brunnstrom Grade (t=0.532, Z<1.79, P>0.05), but electroacupuncture group seemed to improve more. Conclusion Elec-troacupuncture may improve the muscle strength for patients in flaccid paralysis, and promote the recovery of hand function for patients af-ter stroke.

Objective To observe the effect of treadmill training on metabotropic glutamate receptor of a middle cerebral artery occlusion model in rat and its underlying mechanisms. Methods Sprague-Dawley male rats of 2 or 3 months old were randomly divided into 3 groups: a sham operation group, an iscbemia-reperfnsion group and a treadmill training group (subject to 2 weeks of training after the ischemia-reperfusion). All the animals were sacri-ficed after 2 weeks of training and their brains were sampled for measurement of the expression level of the striatum mGluR Ⅰ-mRNA, using RT-PCR technique. Results The striatum mRNA of mGluR1 and mGluR5 was signifi-cantly elevated in the ischemia-reperfusion group(P<0.01), but treadmill training significantly suppressed the ele-vation of the expression of mRNA of mGluR1 and mGluR5 (P<0.01). Conclusions Treadmill training can signif-icantly downregulate mGluR Ⅰ-mRNA expression. This might be one of the important mechanisms for inhibition of the excitatory glutamate production.

Objective To investigate the value of CysC-based CFR in comparison with creatinine-based GFR (CG-GFR and MDRD-GFR) as an accurate serum marker in the prediction of early diabetic nephropathy. Methods A tatal of 133 type 2 diabetic patients (74 males and 59 females, aged 58.1 ±12.3) were enrolled. The level of diabetic nephropathy (normoalbuminuric, microalbuminuric and macroalbuminuric) was staged and estimated GFR based on serum creatinine and cystatin C(CysC) was calculated. The plasma clearance of Tc-DTPA, serum CysC, creatinine, BMI, HbA1c, serum lipid and blood pressure were measured. Results 99mTc-DTPA-GFR was used as golden standard. At 90 and 75 ml· min-1· (1.73 m2)-1 cut-points, diagnostic efficiencies of CysC-GFR (89% and 92%) were better than those of CG-GFR (79%=86%, P=0.004, 0.04) and MDRD-GFR (80%-86%, P=0.02, 0.04). At 60 ml · min-1 · (1.73 m2)-1 cut-point, diagnostic efficiencies of CysC-GFR,CG-GFR and MDRD-GFR were 92%, 90% and 92% respectively (P= 0.49, P=0.71). The Logistic regression analyses showed that retinopathy, HbA1c, CysC, diabetic duration, and CysC-GFR were indicators to predict the development of microalbuminuria. Conclusion CysC-GFR is more valuable than CG-GFR and MDRD-GFR in the prediction of early diabetic nephropathy and should be applied clinically.

AIM: To investigate the protective effects of ulinastatin on the rats with paraquat-induced acute lung injury and its mechanisms .METHODS:The Wistar rats ( n=108 ) were randomly divided into control group , pa-raquat group and ulinastatin group .The rats in paraquat group and ulinastatin group were given paraquat by gavage , while the rats in control group were given sterile saline by gavage .The rats in ulinastatin group were also given ulinastatin treat-ment.The serum levels of MDA, SOD, IL-6, IL-10 and TNF-αwere measured after 1 d, 3 d, 7 d, 14 d, 21 d and 28 d. The expression levels of p 38 MAPK, MMP-2 and TIMP-1 in the lung were also measured .RESULTS:The levels of SOD in 1 d, 3 d and 7 d in paraquat group and ulinastatin group were significantly lower than those in control group ( P<0.01).The level of SOD in ulinastatin group was significantly higher than that in paraquat group (P<0.05).The levels of MDA, IL-6, IL-10 and TNF-αin 1 d, 3 d and 7 d in paraquat group and ulinastatin group increased compared with con-trol group (P<0.01), and those in ulinastatin group were significantly lower than those in paraquat group (P<0.05). The levels of p38 MAPK and TIMP-1 in 1 d, 3 d, 7 d, 14 d, 21 d and 28 d in paraquat group and ulinastatin group were higher than those in control group (P<0.01), and those in ulinastatin group was significantly lower than those in paraquat group ( P<0.05) .The level of MMP-2 in 1 d, 3 d, 7 d, 14 d and 21 d in paraquat group and ulinastatin group increased compared with control group (P<0.01), and that in ulinastatin group was significantly lower than that in paraquat group (P<0.05).CONCLUSION:Ulinastatin protects the lung tissues of rats from paraquat-induced acute lung injury by in-hibiting p38 MAPK signaling pathway and ameliorating inflammatory and oxidative responses .

Objective To reproduce and validate the hexokinase reference method for glucose detection and compare other 5 routine glucose kits with this reference method. Methods The CDC hexokinase reference method for glucose detection was established and the performance was validated through testing a standard reference material (SRM) and participating in the IFCC ring-trial for reference laboratories for glucose evaluation. The CLSI EP 9-A2 protocol was used to compare the 5 routine glucose kits with the hexokinase reference method. Forty serum samples were analyzed by 5 routine kits and the hexokinase reference method. Results When SRM 965a was determined by the reference method,the bias of level 2 and level 3 were 0. 93%, -0. 23% respectively. The results for IFCC ring trial were within the accepted range. For the 5 routine kits, the confidence intervals of the predictive bias at the medical decision point Xc (Xc = 6. 11 mmol/L) were all within the range of defined acceptable error (10%) and the range of biological variation bias (6.9%). Conclusions The hexokinase reference method for serum glucose was reproduced in our lab. The serum glucose results measured with 5 routine kits were different from results detected with the reference method, but the bias was acceptable,and it will not affect the detection results.

Objectives This study was designed to observe the correlation of the levels of serum N-terminal pro-brain natriuretic peptide(NT-proBNP) and high sensitivity C-reactive protein(hs-CRP) between the 3rd day after acute myocardial infarction(AMI) and after 3 months of left ventricular remodeling(LV remodeling) and to establish the predictive levels of NT-proBNP,hs-CRP for LV remodeling after AMI.Methods The blood samples from 106 patients with the first AMI and echocardiography were examined on the 3rd day and after 3 month.LV remodeling was estimated by the changes of left ventricular end-diastolic volume(LVEDV) during the 3rd day and after 3 month.Based on the change of LV remodeling,the 106 patients were divided into two groups:LV remodeling group(defined as the change rate of LVEDV more than 20%) and non-LV remodeling group.Results The correlation coefficients of the change of LVEDV were 0.706 for serum NT-pro BNP and 0.596 for hs-CRP.With a cutoff value of 0.20,the area under the ROC curve(AUCs) was(0.892) for NT-proBNP and 0.825 for hs-CRP.There was no statistically difference between NT-proBNP and hs-CRP.The ROC plot indicated that NT-proBNP was superior to hs-CRP for predicting LV remodeling.Conclusion The level of serum NT-proBNP appropriately reflects LV remodeling after AMI and shows more efficacious than the level of serum hs-CRP.The level of serum NT-proBNP on the 3rd day after AMI and LV remodeling were positively correlated with the level after 3 months.
