BACKGROUND:The interaction of neural network and motor function in post-stroke brain tissue remains unclear.
OBJECTIVE:To observe neural network impairment fol owing subacute stroke by using diffusion tensor imaging, and to investigate the relationship with neurological defects and motor dysfunction.
METHODS:A total of 19 patients after subactue stroke and 20 healthy adults were examined with diffusion tensor imaging. The fol owing parameters were compared:fractional anisotropy, apparent diffusion coefficient, asymmetry indices of fractional anisotropy and apparent diffusion coefficient. The neurological defect and motor function were evaluated with the corresponding scales. The 10-meter walking speed was measured. The correlation of diffusion tensor imaging parameters with the scale scores and 10-meter walking speed was analyzed.
RESULTS AND CONCLUSION:The stroke group exhibited reduced fractional anisotropy value asymmetry and fractional anisotropy value in bilateral posterior limbs of the internal capsule. Apparent diffusion coefficient value asymmetry and apparent diffusion coefficient value in the posterior limb of the internal capsule were lower than control unaffected side (P<0.05). Apparent diffusion coefficient value and apparent diffusion coefficient value asymmetry in posterior limb of the internal capsule showed a strong negative correlation with Fugl-Meyer assessment scores of the lower extremities (P<0.05). Diffusion tensor imaging parameters is closely linked with motor dysfunction of the lower extremities in subacute stroke patients. Local stroke lesion-caused neurological defect is the leading cause of motor dysfunction of the lower extremities.

Objective To examine the effects and mechanisms of siRNA targeting aquaporin 4 (AQP 4) in combination with hyperbaric oxygen therapy(HBO) on cerebral edema and apoptosis in the brain tissue of rats after hemorrhage.Methods Rats were randomly divided into four groups,the control group,the hyperbaric oxygen group,the AQP-4 siRNA group and the combination therapy group (24 rats).Thrombin Ⅶ was injected into the caudate nucleus to establish the hemorrhage model.Construction of siRNA targeting aquaporin 4 was conducted.The mRNA expression of AQP-4 was detected by RT-PCR at day 3.Changes in brain moisture and blood-brain barrier perme ability were measured by a wet/dry weight method and Evans blue fluorometry.The nerve cell apoptosis rate was analyzed by Annexin V andTdT-mediated dUTP-biotin nick end labeling (TUNEL).The expression of proteins including AQP-4,MMP-2,MMP-9,Bcl-2 and caspase-3 was detected by Western Blotting.All the animals were given a score for their nerve function at day 3.Results AQP-4 siRNA treatment obtained better effects than HBO in decreasing the brain edema leveland silencing AQP-4 mRNA(P＜0.05)while,the combination therapy group achieved the best results(P＜ 0.05).Compared with the control group,the percentage of apoptotic cells decreased in all the three treatment groups,with the most marked decrease observed in the combination treatment group(4.24± 0.04)％(F=13.76,P=0.001).The expression of AQP-4,MMP-2,MMP-9 and caspase-3 was lower (P＜0.05) and the expression of Bcl-2 was higher(P＜0.01)in the combination treatment group than in the other three groups.Compared with the control group,all the other three groups received better scores on nerve function defect evaluation at day 3 after hemorrhage(P＜0.05),with the combination treatment group again achieving the most favorable score (4.7 ± 1.1) (F=7.21,P =0.013).Conclusions Targeted siRNA interference combined with hyperbaric oxygen can effectively reduce cerebral edema after cerebral hemorrhage,inhibit neuronal apoptosis and promote neuron function recovery.The underlying mechanisms may be related to down-regulation of AQP-4,MMP 2,MMP-9 and caspase-3 expression and up-regulation of Bcl-2 expression.

Objective To evaluate the value of stereotactic core needle biopsy(SCNB)in diagnosis of breast lesions.Methods Forty-seven cases were punctured with computer-assisted stereotactic system, spring-loaded biopsy guns and 16 G core needles.The record of each item was collected,including clinical manifestations,descriptions of the mammographic characteristics(such as calcification,mass and architectural distortion),the pathology of the SCNB and the surgical pathology or mammographic follow-up data.Then the results of SCNB were analyzed based on the comparison of SCNB pathology and the surgical pathology.The reason that SCNB failed and misdioagnosed was inferred from the relationship of SCNB accuracy and the X-ray characteristics.Results Forty-four cases were punctured successfully,3 cases failed.Thirty-one patients were operated soon after biopsy.The results of 27 SCNB cases agreed well with the final pathology but the other 4 did not.Conclusions SCNB as an accurate,time-saving and cost- effective method,is also minimally invasive and hardly changes the architecture of the breast.SCNB can diagnose breast lesions in advance,reduces the number of surgical biopsy,and is promising in clinical application.

Laboratory animals and animal experiments are foundations and important support conditions for life sciences, especially for medical research. The animal experiments have drawn extensive attention from the society because of the ethical issue. This paper takes Wenzhou Medical University as an example to give a brief introduction to the ethical review about laboratory animals in the university so as to further draw attention and concerns from the public about the ethical issue of laboratory animals. We successively introduce its scientific projects, nurturing environment and ethical review of laboratory animals.

With the combined applications of steam distillation, water extraction and alcohol precipitation, liquid-liquid extraction and column chromatography over macroporous resin, a splitted-fractions method of the chemical constituents of Poria cocos was established. The unoverlapping property of the fractions of P. cocos was qualitatively analysed by using principal component analysis and cluster analysis. With angle cosine, squared euclidean distance and the overlapping analysis of peak area of crude herbs, the unoverlapping property of the fractions of P. cocos was half-quantitatively analysed. The chemical components of P. cocos was divided into the fractions of polysaccharide, petroleum ether, ethyl acetate, alcohol eluate from macroporous resin and water eluate from macroporous resin. Non similarity degree among each chemical fraction was above 80% and main chemical components were identified. The established method for splitting fractions of P. cocos has good stability and repeatability and all chemical components in P. cocos could be completely divided into six fractions. It is the first time that the author half-quantitatively analyse the unoverlapping property of the chemical fractions of P. cocos.
