ABSTRACT
Objective To investigate the expression changes of astrocytic syntrophin in hippocampus from human mesial temporal lobe epilepsy (MTLE). Methods From April, 2015 to July, 2016, 17 cases of hippocampus, collected from temporal lobectomy, were divided into MTLE group (n=13) and non-MTLE group (n=4) according to hematoxylin and eosin staining, glial fibrillary acidic protein and neuronal nu-clei immunohistochemical staining. Immunofluorescence double labeling and immunofluorescence histochemistry were used to observe the expression of syntrophin. Results The proliferation of astrocytes increased and neurons reduced in the hippocampus of MTLE group. Syntro-phin was found in the membrane and foot processes of astrocyte, that was enriched along perivascular astrocyte end-feet domain in non-MTLE group, but lost in MTLE group. While the whole expression of syntrophin was more in MTLE group than in non-MTLE group (t=5.421, P<0.001). Conclusion The distribution of syntrophin in hippocampus astrocytes may be related to the development of MTLE.
ABSTRACT
Objective To examine the diagnosis and outcomes in the treatment of the patients with histologically confirmed central neurocytoma (CNC). Methods The data from 71 patients with CNC who were diagnosed between March 2003 and December 2007 were retrospectively evaluated. Various combinations of surgery, and radiotherapy had been used for treatment. Results The average bulk of tumors was 40 cm3. The median follow-up was 22 months. The 22 months overall survival and local control rate was 95.8%(68/71) and 95.6%(65/68), respectively. Conclusions The overall prognosis is favorable although the follow-up is not very long. Surgery and postoperative radiotherapy can significantly improve local control.
ABSTRACT
Objective To analyze and estimate, the treatment of patients with histologically confirmed subependymal giant-cell astroeytoma (SEGCA). Methods The data from 23 patients with SEG-CA who were diagnosed between February 1995 and February 2008 were retrospectively evaluated. Various combinations of surgery and radiotherapy had been used for treatment. Results Total resection was 16 cases, subtotal resection was 7 cases, radiotherapy was 17 cases. The average follow-up time was 53 months.One postoperative SEGCA recurrence. Epilepsy was totally disappeared in 17.6% (3/17), partly disappeared in 47.1%(8/17). All cases survived. Conclusions The key of treatment is total resection. The significance of radiotherapy is not sure. The overall prognosis of SEGCA is favorable.
