Hematoxylin-eosin staining,immunohistochemistry,electron microscopy and neurological function scores showed that infarct defects were slightly reduced and neurological function significantly improved after nerve growth factor treatment.This result was consistent with diffusion-weighted MRI measurements.Experimental findings indicate that nerve growth factor can protect against cerebral infarction,and that the hemisphere anomalous volume ratio of diffusion-weighted MRI can be used to evaluate the therapeutic effect.展开更多

A 38-year-old female diagnosed as being positive for anti-cardiolipin antibodies was referred to our hospital due to her strong desire to have a baby. The administration of Japanese herbal medicine, Sairei-to, as immunosuppressive therapy, and low dose aspirin, as anti-coagulation therapy, were initiated prior to the patient’s pregnancy. Five months after beginning the treatment, the patient conceived spontaneously. At 34 weeks of gestation, emergency cesarean section was performed due to increasing genital bleeding resulting from coincidental placenta previa and the patient delivered an appropriate-for-date female infant (1970 g). Treatment with Japanese herbal medicine (Sairei-to) and low-dose aspirin is considered to be an effective treatment option for patients positive for anti-phospholipid antibodies with past histories of abnormal pregnancies.展开更多

They were randomly divided into study group and study group, 44 cases in each group. The patients in the control group were treated with oral clopidogrel. On the basis of this, the patients in the study group were treated with atorvastatin;all patients were treated for 4 weeks. Compared the total effective rate, adverse reaction rate, coagulation function index and blood lipid level between the two groups, and compared the NIHSS score and daily life ability (ADL) score between the two groups before and after treatment.Results: The total effective rate (90.90%) was significantly higher in the study group than in the control group (72.73%). After treatment, the NIHSS score of the study group was significantly lower than that of the control group. The levels of LDL-C, TG and TC in the study group were significantly lower than those in the control group, and HDL-C was significantly higher than that in the control group. There was no significant difference between the two groups.Conclusion: Clopidogrel combined with atorvastatin has a significant effect on the patients with intracranial large artery stenosis and improve the neurological function and quality of life. It is safe and reliable. It is worthy to be popularized.展开更多
