Conclusion: Long-term running exercises can increase the cross-sectional area of the anterior thigh muscles. Long-term endurance running training may counteract the effects of age on muscles. There was no significant correlation between running-related age, pace, and monthly running amount and thigh muscle cross-sectional area.]]> Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.010 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.011 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.012 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.013 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.014 ^, cerebrospinal fluid samples were collected for biochemical and cytological examinations. Changes in cerebrospinal fluid indicators during anti-tuberculosis treatment were analyzed, and the value of MRI and cerebrospinal fluid examination in evaluating the curative effect of anti-tuberculosis treatment was summarized. Results: In 400 cases with intracranial tuberculosis, there were 179 cases (44.75%) with simple brain parenchymal tuberculosis, 71 cases (17.75%) with tuberculous meningitis and 150 cases (37.50%) with mixed intracranial tuberculosis. A total of 425 lesions were detected in patients with simple brain parenchymal tuberculosis, including 196 of miliary type, 167 of nodular type, and 62 tuberculomas. MRI findings were as follows: even signals, slightly longer or equal T1 signals, long or slightly longer T2 signals; uneven signals, long or equal T1 signals and long T2 signals in the center, slightly longer or equal T1 and T2 signals at the edge. Enhanced scan showed homogenous enhancement, circular enhancement and solid enhancement. The disappearance rate of miliary lesions was higher than that of nodular ones and tuberculoma at 1 month, 3 months and 6 months after treatment. MRI of patients with tuberculous meningitis showed gyrus-like high signal on T2WI, equal or low signal on T1WI. After enhanced scan, the meninges showed radial enhancement, dominated by enhancement in the suprasellar cistern meninge, ambient cistern meninge, and quadruplet cisternal meninge. After treatment, meninge enhancement and thickening were relieved, and meningeal lesions were improved. The MRI findings of patients with mixed intracranial tuberculosis had both the MRI signs of simple brain parenchymal tuberculosis and tuberculous meningitis. After treatment, the meningeal lesions were improved, and some had enlarged or increased meningeal nodules. One month, 3 months and 6 months after treatment, the levels of protein, white blood cells, neutrophils and lymphocytes in patients with intracranial tuberculosis decreased, while the levels of chloride and glucose increased (P＜0.05). Conclusions: Different types of intracranial tuberculosis have obvious MRI features. Having a clear understanding of dynamic MRI and cerebrospinal fluid changes during anti-tuberculosis treatment is helpful for the evaluation and prediction of clinical anti-tuberculosis treatment effect.]]> Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.015 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.016 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.017 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.018 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.019 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.022 ^,s lymphoma; magnetic resonance imaging]]> Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.023 ^,s disease, and its response to drug therapy and subthalamic stimulation is usually poor, which seriously affect the quality of life. As a part of mesencephalic locomotor region and reticular activating system, the pedunculopontine nucleus is closely connected with the basal ganglia, thalamus, cerebellum and other brain regions, and participates in posture and gait control. Diffusion tensor imaging (DTI) and functional magnetic resonance imaging (fMRI) can reflect the structure of white matter fiber tracts and the function of brain regions, who well assess the role of the pedunculopontine nucleus in postural instability/gait difficulty. This article will review the application of DTI and fMRI in the network connection of the pedunculopontine nucleus in Parkinson^,s patients.]]> Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.024 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.025 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.026 ^,s diagnosis.]]> Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.027 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.028 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.029 Thu,20 May 2021 00:00:00 GMT http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2021.05.030 Thu,20 May 2021 00:00:00 GMT
