Objective To study the clinical significance of the content of ? 2-microglubin and activity of ?-glucuronidase in cerebrospinal fluid (CSF) of patients with cerebral tumor. Methods The activities of ? 2-microglubin and ?-glucuronidase in CSF of patients with cerebral tumor and non- cerebral tumor were analyzed by radioimmunoassay and enzyme-linked immunosorbent assay (ELISA) respectively. Results the activities of ? 2-microglubin and ?-glucuronidase in cerebral malignancy were obviously higher than that of cerebral benign tumor (P

Objective To evaluate the clinical value of interventional chemotherapy and intravesical instillation for preventing postoperative recurrence and metastasis of cancer in urinary bladder.Methods One hundred and eight patients with urinary bladder cancer were divided into group A and group B.Intravesical instillations after surgical operation were performed in group A (n=52) and combined interventional chemotherapy and intravesical instillations after operation were performed in group B (n=56).The patients were followed up for 1 - 3 years.Results In group A,recurrence occurred in 5 cases (9.62%) within one year,and in 23 cases (44.23%) within 3 years after the operations metastasis developed in 21 cases (40.38%),and 18 cases (34.62%) died.In group B,recurrence occurred in 2 cases (3.57%) within one year,and in 11 cases (19.64%) within 3 years after the operation;metastasis developed in 7 cases (12.50%), and 5 cases (8.93%) died.There were statistical significant differences in recurrence,metastasis and mortality between these two groups (P

Attention deficit hyperactivity disorder(ADHD)is a common childhood behavioral disorder,and it is characte-rized by the core symptoms of attention deficit,hyperactivity and impulsivity.In recent years,a variety of neuropsychological deficits related to ADHD have been confirmed,including intelligence,attention and inhibition,verbal and spatial working memory,set shift,planning and monitoring.Some important theories related to the metal mechanism of ADHD have been put forward,and the representatives include behavioral inhibition theory,cognitive-energetic model,dual pathway theory and state regulation theory.

Objective To study the neuro-protective effects of magnetotherapy after traumatic brain injury of rats. Methods Traumatic brain injury models were created in 20 rats and divided randomly into magnetotherapy and non-magnetotherapy groups. The rats in magnetotherapy group received magnetotherapy on the cranial surface of traumatized region twice daily, each for 20 min, over 10 d. The intensity of magnetic field was O. 15 T at the surface,and 0.1 T during spinning at 3000 rpm. The contraction strength of gastrocnemius of each rat's left hind limb was measured on the 11 th d after trauma. The rats were then sacrificed and brain tissue samples were taken. The infiltra-tions of CD4 + and CD8 + cells and apnptosis in the area around the injury lesion were observed with immunohisto-chemical methods. The relationship among the indexes was analyzed. Results At the 11th d after brain injury, the quantities of CD4 + and CD8 + cells and apoptotic cells in magnetotherapy group were all obviously less than those in non-magnetotherapy group. Average contraction strength of gastrocnemius in magnetotherapy group was significantly stronger than that in non-magnetotherapy group. Conclusions Magnetotherapy can relieve the secondary effects of brain injury and induce neuro-protection effects. This may involve decreasing the local infiltrations of CD4 + and CD8 + and apoptotic cells in the area around the injury lesion.
