Objective To study the value of transfer constant(Ktrans)derived from dynamic contrast-enhanced MRI (DCE-MRI) for quantitative evaluation of Ki-67 labeling index (Ki-67 LI) in glioma. Methods Twenty patients with glioma who underwent DCE-MRI and operation were retrospectively reviewed. The Ktrans value and Ki-67 LI were acquired and correlated using the Spearman correlation test. Also, the Ktrans values were compared between high(larger than 10%)and low(no more than 10%)Ki-67 LI group with Mann-Whitney U test, receiver operating characteristic curves was performed to evaluate the diagnostic value. Results The Ktrans value(0.0165 to 0.8048, median 0.1252)was significantly associated with Ki-67 LI(5%to 50%, median 20%) (r=0.721,P<0.001), and the Ktrans value was significantly higher in high Ki-67 group(0.0810 to 0.8048, median 0.1810)than that in low Ki-67 LI group(0.0165 to 0.1456, median 0.0697)(Z=-3.209, P=0.001). The most predictive Ktrans value differentiated high Ki-67 LI and low Ki-67 LI with an area under the curve(AUC) of 0.945 at a sensitivity of 92.3% and specificity of 85.7%. Conclusion Ktrans value could be used for quantitative evaluation of Ki-67 LI in glioma.

Objective To evaluate three different tracer-kinetic models used for dynamic contrast-enhanced MRI (DCE-MRI) data processing in the prediction of the histopathologic grade of cerebral gliomas.Methods Forty-one patients with histopathologically graded gliomas (grade Ⅱ 13,grade Ⅲ 14,grade Ⅳ 14)were imaged with DCE-MRI from March,2013 to November,2014.The values of Ktrans of gliomas were obtained by three tracer-kinetic models,which were Patlak model,Tofts model and Extended Tofts Linear model.All data were analyzed statistically by a Graphpad 6.0 statistical software.Comparison of the differences of Ktrans among different grades of gliomas was conducted using the Kruskal-Wallis test and Dunn's multiple comparisons test for the data not conform to normal distribution.Correlations of Ktrans values among those three models were analyzed using linear regression analysis,The differences of Ktrans between low grades and high grades of gliomas was conducted using the Mann-Whitney U test.Receiver operating characteristic (ROC) curve analyses were performed to determine the cut-off values for Ktrans to distinguish different low grades and high grades of gliomas.Results The Ktrans values obtained by Patlak model was 0.008(0.004-0.043) min-1for grade Ⅱ,0.021(0.005-0.088) min-1 for grade Ⅲ,and 0.035(0.017-0.061) min-1 for grade Ⅳ.The Ktrans values obtained by Tofts model was 0.085 (0.041-0.158)min 1for grade Ⅱ,0.140 (0.063-0.315) min-1for grade Ⅲ,0.229 (0.126-0.419)min 1 for grade Ⅳ.The Ktrans values obtained by Extended Tofts Linear model was 0.012 (0.004-0.092) min 1 for grade Ⅱ,0.048 (0.010-0.188) min-t for grade Ⅲ,0.094 (0.036-0.215)min 1 for grade Ⅳ.All the Ktrans values obtained by three models increased when the histological grades increased,with statistical significance between grade Ⅱ and Ⅲ (H=18.31,18.09,20.18,P＜0.05).Ktrans values among the three models had good linear correlations.The Ktrans obtained by Extended Tofts Linear model had good linear correlations with both Patlak model and Tofts model (r=0.933,0.893,P＜0.05),and the Ktrans obtained by Patlak model had less linear correlation with Tofts model (r=0.822,P＜0.05).The K values were statistically different between LGG and HGG (P＜0.01).The cut-off value of K provided good combination of sensitivity and specificity in the differentiation between LGG and HGG,and the K obtained by Extended Tofts Linear model had the best sensitivity and specificity among the three models (sensitivity 92.3％,specificity 85.7％).Conclusions K from DCE-MRI has a high performance in predicting the histopathologic grade of brain glioma,and the Extended Tofts Linear model is more suitable for the evaluation of cerebral glioma.

Objective:To investigate the effects of epidural spinal cord stimulation (ESCS) and treadmill training on the locomotion function and ultrastructure of spinal cord anterior horn after moderate spinal cord injury in rats. (IT, n=3). All rats received a moderate spinal cord injury surgery. Four weeks after surgery, rats in SE group received an electrode implantation procedure, with the electrode field covering spinal cord segments L2-S1. Four weeks after electrode implantation, rats received subthreshold ESCS for 30 min/d. Rats in TY group received 4cm/s treadmill training for 30min/d. Rats in SI group received no intervention, as a control group. All procedures in these three groups lasted four weeks.The open field Basso,Beattie and Bresnahan (BBB) scale was used before and after intervention to evaluate rats' hindlimb motor function. Result:After four weeks intervention, rats in TT group improved their open field locomotion scores to 20. In contrast, no significant improvement was observed in groups SI and SE. The morphology of synapses and neurons were similar regardless of whether rats had undergone ESCS, treadmill training or not. Conclusion:ESCS alone was not sufficient to improve the walking ability of spinal cord injured rats. ESCS or treadmill training alone might not contribute to the changes of ultrastructure in anterior horn of spinal cord that underlie the recovery of walking ability. Further research is needed to understand the contributions of combination of ESCS and treadmill training to the rehabilitation of spinal cord injured rats.

Objective To identify the gene mutations of platelet membrane glycoprotein Ⅱ b,Ⅲa(GPⅡb/Ⅲa)in three Chinese pedigrees with Glanzmann thrombastIlenia.Methods All exons and exonintron boundaries of GP Ⅱ b/Ⅲ a gene were amplified by PCR analysis followed by DNA sequencing.DNA sequencing was used to exclude gene polymorphisms.Results The probands in the three pedigrees had a normal platelet count,coagulation profiles,scattered platelets on the blood film,a prolonged cutaneous bleeding time,and impaired or minimal ex vivo platelet aggregation in response to ADP,thrombin,collagen,adrenaline and arachidonic acid,but normal platelet aggregation in response to ristoeetin.Both FACS and Western blotting demonstrated trace content of αⅡb in the platelets from proband 1 and proband 3,who were classified as type Ⅰ GT,and a small amount of αⅡb in the platelets from proband 2,who was classified as type Ⅱ GT.Compound heterozygous mutations,T2255G(Leu721Arg)and C2671T(Gln860Stop)were identified in proband 1.The proband 2 had homozygous A2334C(Gln747Pro)missense mutation.Nonsense mutations C1750T (Arg584Stop)and 69-79 deletion mutation were identified in proband 3. Conclusions Compound heterozygous mutations T2255G and C2671T of αⅡb gene lead to type Ⅰ Glanzmann thrombasthenia for proband 1. Homozygous mutation A2334C of αⅡb gene leads to type Ⅱ Glanzmann thrombasthenia for proband 2. Compound heterozygous mutations C1750T and 69-79del αⅡb gene lead to type Ⅰ Glanzmann thrombasthenia for proband 3. T2255G,C1671T and 69-79del aye novel mutations for αⅡb gene.

Objective To investigate the relationship between serum transforming growth factor- β1(TGF- β1) levels and early diabetic nephropathy and clarify whether valsartan plays a role in renal protection by reducing the level of serum TGF-β1. Methods The study subjects were divided into four groups:control group (30 cases); normal albuminuria group 1 (NA1 group with 12 cases, U MA/Cr < 10 μg/mg combined with type 2 diabetes);normal albuminuria group 2 (NA2 group with 19 cases,UMA/Cr 10-30 μg/mg combined with type 2 diabetes); microalbuminuria group ( MA group with 35 cases, U MA/Cr 31-300 μg/mg combined with type 2 diabetes). All these type 2 diabetic patients were suffering from diabetic retinopathy, and valsartan ( 80 mg/d) were medicated for those combined with hypertension. The serum TGF-β1 levels were measured by enzyme-linked immunosorbent assay in all subjects. Results Serum TGF- β1 levels in three diabetes groups were (7.41 ± 2.68 ), ( 10.52 ± 4.10), (22.98 ± 43.74) ng/L, respectively, all of which were higher than those in control group [(4.25 ± 5.82) ng/L] (P < 0.05). There were significant differences in serum TGF- β1 levels among MA group, NA2 group and NA1 group (P < 0.05 ). Serum TGF-β1 levels in NA1 group with valsartan treatment significantly decreased compared with those without valsartan treatment (P < 0.05), whereas there was no significant reduction in NA2 and MA group with valsartan treatment (P > 0.05). Conclusions High serum TGF-β1 level may be associated with type 2 diabetes and early diabetic nephropathy. Early intervention of valsartan may be delay the onset and development of diabetic nephropathy by decreasing the serum TGF-β1 level.

Objective To investigate the effects of epidural spinal cord electrical stimulation (ESCES) on spinal cord reflexes in normal adult rats, and to find out where and how the spinal cord reflexes are generated. Methods Ten adult female Sprague Dawley rats were anaesthetized and an electrode was placed at the S, spinal cord segment. Single electric pulses with 200 μs pulse width and voltages of 400 mV, 600 mV and 1200 mV were used in the ESCES. 1200 mV voltages with 50 Hz, 60 Hz, 80 Hz, 100 Hz frequency were also tested. EMG signals were re-corded with concentric needle electrodes in the rats' semitendinosus muscles to observe the characteristics of spinal cord reflexes. Results The voltage threshold for generating semitendinosus muscle response was 300 mV. The three ESCES voltages induced 2 kinds of spinal cord reflexes. The 400 mV and 600 mV stimulation induced spinal cord reflexes with short latency (5.27±0.36 ms and 5.19±0.67 ms respectively). The 1200 mV stimulation volt-age induced spinal cord reflexes with long latency (2.57±0.23 ms). Spinal cord reflexes could be generated by 50 Hz, 60 Hz, 80 Hz, and 100 Hz ESCES. At the higher frequencies, spinal cord reflexes declined late in the ex-periments and then appeared irregular. In some of the rats, spinal cord reflexes vanished entirely late in the stimula-tion experiments. The latency and duration of the spinal cord reflexes induced by 50 Hz ESCES were (4.46 ± 1.07) ms and (7.33±1.00)ms respectively. These were significantly different from the latency and duration initia-ted by 60 Hz, 80 Hz or 100 Hz ESCES. Conclusions Different ESCES voltages induce different spinal cord refle-xes generated differently. The long latency reflexes might be monosynaptic responses mediated by dorsal root excite-ment, while the short latency reflexes might be sarcous exciting electric activity mediated by direct excitement of mo-tor neurons or motor fibers. The irregular spinal cord reflexes induced by higher frequency ESCES might be one kind of monosynaptic response. Irregularly appearing spinal cord reflexes induced by higher frequency stimulation might due to the inhibitory effect of higher frequency stimulation.
