Chinese Journal of Physical Medicine and Rehabilitation 2011;33(10):731-735
Objective To study the effects of rehabilitation training on the regeneration of nerve cells in rats after intracerebral hemorrhage (ICH).Methods A total of 75 male SD rats were randomized into a training group,a control group and a sham operated group,25 rats/group.The ICH models were induced by stereotactical injection of collagenase type Ⅶ into the globus pallidus.The training group was trained with grasp,balancing and rotating exercise every day,the control group was restricted to their cages,and the sham operated group received normal saline injections.Each group was further subdivided into 1,4,7,14 and 28 day subgroups.Neurological function was measured in each group.Bromodeoxyuridine (BrdU) was used to label S phase cells,immunohistochemical single and double staining with antibodies against BrdU,microtubal-associated protein (MAP) and neuronal nuclei (NeuN) were used to determine neuronal proliferation,migration and differentiation in the subventricular zone ( SVZ ) and subgranular zone (SGZ) in the training and control groups.Results The motor function scores of the animals in the rehabilitation group were significantly lower than those of the control group.Proliferative BrdU + cells of the SVZ and SGZ in the control group rats were clearly less than those in the rehabilitation training rats at all time points.The results of the immunohistochemical double staining indicated that one week after ICH BrdU +/MAP + cells in the SVZ had increased significantly in the training group compared to the control group,and then decreased two weeks later.At the same time,BrdU +/MAP cells were found in the striatal boundary on the hemorrhage side,in numbers up to 8 times that in the control group.In the rehabilitation group striatal neuron differentiation on the hemorrhage side was 2 to 3 times that in the control group.Conclusion Rehabilitative training can enhance nerve cell proliferation,regeneration and neuron migration after ICH.

A study on the optimal dilution of serum to detect anti HBc-IgM with ELISA. was carried out. Samples were diluted to 10-1to 10-7. Among 26 samples of normal individuals, 22 were negative, but two samples of 10-1 dilution, one sample of 10-2, and one sample of 10-1-10-3 were positive though the control wells were all negative. 42 samples of the patients with variours types of hepatitis B were examined. It was found that when serum dilution was 10-1, only 6 cases were positive; when the dilution was 10-2, 20 cases were positive; when the dilutions were 10-3, 5?10-3, and 10-4, high positive rates were obtained and they were 88.1%, 78.5%, and 69% respectively; and when the samples were further diluted, the positive rate decreased.In order to get goodfresults and minimize false results, either false negative or false positive, it is suggested that 5?10-3 be the optimal dilution.

Objective To value the clinical application of diffusion tensor imaging (DTI) in cerebral diseases. Methods Six volunteers and 6 patients (including 3 patients with ischemic stroke and 3 patients with glioma) were examined by DTI and T1weighted, T2weighted MR scan. All data were processed with DtiStudio software to show the white matter fiber tracts. The fractional anisotropy (FA) of the diffusion tensor were measured between the affected and the unaffected side. Results The white matter fiber tract could be observed clearly on the FA map. The pyramidal tract with different degree disruption could be showed in 3 patients with ischemic stroke. Compression, displacement, infiltration or destruction of pyramidal tract, corpus callosum or internal capsule and external capsule could be seen in 3 patients with glioma, and FA was significantly reduced on the affected side as compared to the unaffected side. Conclusion Diffusion tensor imaging is useful in observing the damage and displacement of the white matter fiber tracts in vivo, beneficial to the surgical plan for patients and prognosing recovery of function.

Objective To discuss the clinical features diagnosis and treatment of cerebral schistosomiasis. Methods A to?tal of 166 patients with cerebral schistosomiasis were treated and their clinical data were collected and analyzed retrospectively. Results In 166 cases of cerebral schistosomiasis the confirmative diagnoses of 156 cases were diagnosed according to the clin?ical manifestation etiology immunology and auxiliary examination CT MRI .In among 74 cases were confirmed by pathologi?cal examination 10 cases were diagnosed through to the diagnostic treatment. Totally 102 patients received the oral medication of praziquantel and they all improved and discharged 14?16 days later 64 patients received the craniotomy and praziquantel medication after the operation and 48 patients significantly improved others did not improve or aggravated. There was no opera?tive mortality. Conclusions Neuroimaging and laboratory tests are valuable in the diagnosis of cerebral schistosomiasis. The praziquantel treatment is selected firstly when the diagnosis was established. However in the case of serious intracranial hyper?tension intractable epilepsy and praziquantel treatment fails the surgical treatment is required.

Aim To observe the expression of epider-mal growth factor receptor ( EGFR) in cerebral tissues around hematomas after intracerebral hemorrhage, and explore the effects of EGFR on activation of astrocytes derived from rats and the involved mechanisms. Meth-ods The specimens of cerebral tissues around hemo-tomas after intracerebral hemorrhage undergoing hemo-tomas removal operation were collected and then divid-ed into 4 groups according to the time of intracerebral hemorrhage: <1 d, 1 ~5 d, 6 ~10 d and >10 d groups. Each group included 20 cases. At the same time, 20 dropped brain tissues distant to hemorrhage in the operative process were collected as control group. Immunohistostaining and Western blot were used to measure the expression of EGFR. After isolation and culturing, the astrocytes of rat cortex were treated with culture solution ( control group) , CNTF that was used to activate astrocytes, scramble siRNA + CNTF and EGFR siRNA +CNTF for 24h, respectively. The ex-pression of glial fibrillary acidic protein ( GFAP) mR-NA was detected through fluorescence real-time quanti-tative PCR. In addition, the protein levels of GFAP, signal transducers and activators of transcription 3 ( STAT3 ) and phosphorylated STAT3 ( p-STAT3 ) were examined using Western blot. Results With the ex-tension of intracerebral hemorrhage time, positive sig-nal index and protein expression levels of EGFR gradu-ally elevated, reached the peak on 6 ~10d, and then decreased after 10 d. There was statistical difference ( P<0. 01 ) . The expression levels of GFAP mRNA and protein as well as p-STAT3 were significantly in-creased in cells treated with CNTF alone as compared to control group ( P <0. 01 ) , whereas these effects were almost completely reversed by EGFR siRNA transfection ( P <0. 01 ) . Additionally, there was no statistical difference in STAT3 protein levels among groups ( P >0. 05 ) . Conclusions EGFR expression is upregulated in the cerebral tissues around hemotomas after intracerebral hemorrhage. Gene silence of EGFR contributes to suppressing the activation of astrocytes derived from rats, which may be involved in the block-ade of STAT3 phosphorylation.

To control the quality of Humulus scandens, the quality standard was established in this study. According to the method recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition) , the water and ash inspections were carried out. The component luteoloside and cosmosiin in Humulus scandens were identified and assayed by TLC and HPLC. The results showed a strong characteristics microscopic of Humulus scandens, and trichoromethane-methanol-formic acid (10: 3: 0. 3) as the mobile phase of TLC, the spots at 365 nm with a UV lamp was clear. The 16 batches of samples were analyzed by HPLC with a gradient elution of acetonitrile and phosphate solution (0.2%) at a flow rate of 1.0 mL · min(-1) and detected at 350 nm. The content of luteoloside was 0.015%- 0.651% (average 0.148%); the content of cosmosiin was 0.003%-0.118% (average 0.036%). The linear calibration curve of luteoloside and cosmosiin was acquired in the ranges of 0.011-0.364 g · L(-1) (r = 1.000 0) and 0.003-0.096 g · L(-1) (r = 1.000 0), respectively. The average recovery was 100.5% and 98.5%, respectively. The methods are convenient and reliable, which can be ap- plied for quality assessment of Humulus scandens.
