Senile dementia: differentiation of syndromes according to meridians based on the theory of "cerebral collaterals injury by toxin" / 中国针灸

The pathogenesis and treatments based on meridian differentiation of senile dementia are discussed through analyses and researches on the theory of "cerebral collaterals injury by toxins" and "collateral diseases". The symptoms of "Cerebral collaterals injury by toxins" are preliminary characterized by toxins and blood stasis occluding brain collaterals. "Cerebral collateral injury by toxins" and "Governor Vessel occlusion by blood stasis" are taken as the major pathogeneses of senile dementia. And the treatment should be focused on clearing the collaterals. Clearance acting as reinforcing as well as to clear and modify the Governor Vessel are taken as crucial sections in the treatment of senile dementia based on meridian differentiation. It is also the application of acupuncture-moxibustion intervention in senile dementia based on the theory of "cerebral collateral injury by toxins", which expands the application of the theory concerning "collateral diseases" in disease prevention and treatment with acupuncture-moxibustion.

Estimation of spike wave reduction in electrocorticography for predicting the outcomes of epilepsy surgery / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate spike wave reduction in electrocorticography (EcoG) monitoring for evaluating the outcomes of epilepsy surgery.</p><p><b>METHODS</b>The epileptogenesis lesions in the target cortex was localized accurately using an EcoG monitoring system in 20 surgical patients with intractable EP. The spike numbers within 60 s were recorded before and after surgical resection of the epileptogenic focus. In cases where the spike number within 60 s was reduced by over 80% after the resection, the surgery was terminated, otherwise extended lesion resection, corpus callosotomy or multiple subpial transection (MST) was carried out with ECoG monitoring, and the spike number within 60 s was recorded. Antiepileptic drugs were routinely prescribed after the operations.</p><p><b>RESULTS</b>Twelve patients exhibited a spike wave reduction by over 80% after resection or extended resection of the lesions, including 4 with cavernomas in the nonfunctional area, who showed a spike wave reduction by over 80% after extended resection of the cortex around the tumor. The reduction was still less than 80% in 4 patients with hippocampal sclerosis and 3 with neurogliocytoma in the functional area after the operations. According to the Engel assessments, 13 cases were in level I, 3 cases in level II, 1 in level III, and 3 in level IV. Seventeen patients responded favorably to the treatment, with a total effective rate of 85%.</p><p><b>CONCLUSION</b>For extra-temporal lobe epilepsy, a postoperative spike wave reduction beyond 80% indicate favorable outcome of the surgery, otherwise poor prognosis is expected. But in cases of temporal lobe epilepsy, no direct association is found between spike wave reduction and the prognosis of the patients.</p>

The experimental study of mechanism of integrin in hypertrophic scar contracture / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study the mechanism of integrin in hypertrophic scar.</p><p><b>METHODS</b>Fibroblasts from 10 samples of human hypertrophic scars was cultured, FQ-PCR assay was applied to detect mRNA expression of alpha-SMA in hypertrophic scar fibroblasts after integrin and FAK antibody blocking.</p><p><b>RESULTS</b>mRNA of alpha-SMA in fibroblasts expressed obviously lower after integrin and FAK antibody blocking than that of control groups ( P < 0.05).</p><p><b>CONCLUSION</b>Through accelerating the synthesis of alpha-SMA, integrin and FAK play an important role in contracture of hypertrophic scar.</p>
