Objective To investigate the effect of nerve growth factor (NGF) on the neural cells and expression of early growth response gene-1 (Egr-1 gene) in the hippocampus discharge zone of childhood intractable epileptics. Methods Acutely dissociated cell suspensions of childhood hippocampus discharge zone with non specific pathological changes (n = 16) were exposed to NGF group and control group respectively. There were three subgroups exposed to NGF at the levels of 12.5, 50, 100 ng/ml in NGF group. After 4 hr culturing, the astrocytes and neurons were lablled by Bb immunostain with the specific markers such as GFAP and MAP2. The total number of neural cells was counted under inversion fluorescence microscope and the Egr-1mRNA expression was detected by semiquantitative RT-PCR analysis. Results There were significant differences of the numbers of neural cells survived in hippoeampus region between the NGF group and the non-added NGF group (P < 0.01). Among the different levels of NGF 12.5, 50, 100 ng/ml, the number of the total cultural neurons and GFAP(+) astrocytes, MAP_2(+) neurons were increased with ascending levels of NGF (P < 0.05). At the same time, the expression of Egr-1mRNA (A_(Egr-1)/A_(β-actin)) in the NGF groups was also increased (P < 0.01). There was positive correlation between the number of the survivable neural cells and Egr-1mRNA quantity (r = 0.780, P < 0.01) among the three NGF groups. Conclusions NGF can protect the neural cells of epileptic discharge zone by promoting the expression of Egr-1 gene.

OBJECTIVE: To explore whether there are beta-amyloid protein (Abeta) binding elements in heart-beneficial recipe (HBR, a compound traditional Chinese herbal medicine), which can ameliorate the cytotoxicity of Abeta. METHODS: The extract of HBR and Abeta(1-40) were co-precipitated, and the Abeta(1-40) in pellets was detected by immunoblotting. Affi-gel-Abeta(1-40) was constructed, and Affi-gel-Abeta(1-40) affinity elements from the extract of HBR were analyzed by high-performance liquid chromatography (HPLC). The assay of lactic dehydrogenase (LDH) release from the primary cultured rat cortex neurons was used to evaluate the cytotoxicity of Abeta(1-42), and the protection effects of the HBR serum and the Affi-gel-Abeta(1-40) treated HBR serum. RESULTS: Immunoblotting examination showed Abeta(1-40) could be co-precipitated with components of HBR following co-incubation, and the amount of Abeta(1-40) within pellets decreased when the HBR extract was diluted. Abeta(1-40) affinity elements from the extract of HBR, eluted from Affi-gel-Abeta(1-40) by glycine solution (pH=2.5), could be detected by HPLC-fluorescent detector system. The analysis of LDH release showed that exposure of neurons to 5 micromol/L Abeta(1-42) for 48 h caused a significant increase of LDH release in either a serum free or 10% serum contained culture condition (P<0.01). The rat HBR serum was able to suppress Abeta(1-42) induced LDH release (P<0.05), whereas Affi-gel-Abeta(1-40) treated HBR serum still maintained the ability to attenuate Abeta(1-42) induced LDH release although the effect was somewhat decreased compared with Affi-gel treated HBR serum. CONCLUSION: There are Abeta affinity components in HBR, which could not increase the Abeta cytotoxicity, but might be able to inhibit the cytotoxicity of Abeta. The results implied that the exploration of Abeta affinity elements from Chinese medicinal recipe which is effective for Alzheimer disease, might be an important direction in Alzheimer disease therapeutic research area.

OBJECTIVE: Synovial sarcoma (SS) of the head and neck is rare in comparison with those took place in the extremities. This study was planned to investigate the relationship between pathological diagnosis, tumor location and clinical outcome of SS of the head and neck. METHOD: Thirty-nine cases of SS in head and neck hospitalized in West China Hospital from 1966 to 2011 was retrospectively studied by reviewing the medical record data, the pathological slices of the operative specimen and followed-up from 1 to 192 months with the mean time of 43.2 months postoperatively. The parameters of clinical outcome were focused on the time to first recurrence after primary surgery and follow-up time. The reviewed results were statistically processed. RESULT: The age of the patients ranged from 8 to 66 years old with the median age of 35, among them 27 are males. Pathologically, 18 cases are biphasic, 17 cases are monophasic and 3 cases are low-differentiated SS. 4 cases were proved by cytogenetic methods of either fluorescence in situ hybridization(FISH) or RT-PCR. 23 cases experienced repeated recurrence with the most up to 4 times operations after sole surgical approach. Only one lymphatic metastasis was suspected in all. 16 patients got adjuvant radiotherapy or chemotherapy. 4 patients died but only one death was associated directly with SS recurrence. There was no significant relationship between pathological subtype and recurrence (Fisher's Exact Test P-value > 0.05), no significant relationship between tumor location and recurrence (Fisher's Exact Test P-value > 0.05). CONCLUSION SS of head and neck is a special entity that has potential of easy recurrence but good prognosis. Surgery should still be the primary treatment approach. Cytogenetic methods are recommended to as certain the diagnosis in order to choose reasonable treatment protocols.
