Objective To study the pathologic changes of hippocampus during the model development and explore the mechanism of epileptogenesis by observing the morphologic changes of hippocampal formation in rat of kainate-induced chronic temporal lobe epilepsy (TLE). Methods Thirty Wistar rats were injected of Kainic acid at dose of 2 ?g/20 ?l into the lateral cerebral ventricle under the guidence of stereotactic technique to make a epileptic focus, and subgrouped under acute phase, silent period and chronic phase. Another 10 rats received normal saline as controls. The rats were killed at 1 day, 15 day and 6 months after epileptic model establishment, and the hippocampus was taken out for HE staining, TUNEL staining, Timm’s staining, NSE staining. Results By cell counting, the neuron loss mainly occurred in acute phase, worst in CA3 and CA4, moderate in CA1 and CA2, and no loss in the dentate gyrus. The cell apoptosis in hippocampal structure was detected by TUNEL staining. Timm’s staining showed that mossy fiber began sprouting in silent period and increased continuously. Conclusion The morphologic changes of hippocampal formation in rat of kainate-induced TLE is mainly the neuron loss and the glia hyperplasy.

Objective To study the clinical features, effects of therapeutic regimen and prognosis of patents with mantle cell lymphoma (MCL). Methods Clinical data of 27 MCL patients admitted in Tianjin Medical University Cancer Institute&Hospital from January 2008 to December 2014 were retrospectively analyzed. Cox regression analysis was used to analyze influencing factors of prognosis of MCL. Results The median age was 68 years old for 27 patients, and the male-to-female ratio was 4.4∶1. Ann Arbor staging showed that 25 cases were stageⅢ-Ⅳ(92.6%), 8 cases were heptosplenomegaly (29.6%), 7 cases showed extranodal involvement (25.9%). ECOG scoring showed that 4 cases with scores of 2-4 (14.8%), 8 cases were 0-3 (29.6%), 14 cases were 4-5 (51.9%) and 5 cases were 6-11 (18.5%). The Ki-67 index≤30%was found in 9 cases (33.3%), and>30%was found in 18 cases (67.7%). Patients with B symptom was found in 10 (37.0%). The elevated lactate dehydrogenase (LDH) was found in 17 cases (63.0%). The increased Beta 2- microglobulin was found in 8 cases (29.6%). Seven patients were found with bone marrow involvement. The total effective rate (ORR) was 81.8%in group with R-CHOP method, and the ORR was 68.8%in group with CHOP method. Multivariate analysis showed that age, LDH and Ki-67 were independent factors influencing the prognosis of MCL (P<0.05). Conclusion Most patients with MCL are found in advanced stage. Patients with age>60 years, elevated LDH and Ki-67 index>30%are with poor prognosis.

Objective To investigate cerebrospinal fluid characteristics and clinical features in children with severe hand,foot and mouth disease (HFMD) induced by enterovirus 71 (EV71) infection.Methods A total of 114 children with severe HFMD,in whom EV71 was detected by reverse transcription polymerase chain reaction (RT-PCR),were admitted in Hangzhou Children's Hospital during May and August 2013.Seventy-eight children with severe HFMD induced by other enteroviruses admitted at the same period served as controls.The results of cerebrospinal fluids (CSF) routine examination and biochemical tests,and the clinical symptoms were compared between two groups.Differences in enumeration data were compared with x2 test,and measurement data were compared with Mann-Whitney U test.Results The incidences of vomiting and limb shaking in EV71 infection group were 35.1％ and 50.9％,which were higher than those in control group (x2 =7.864 and 19.682,P ＜ 0.05).The incidence of limb shaking in children with nucleated cells count ≥ 100 × 106/L in EV71 group was higher than that with nucleated cells count ＜ 100 × 106/L (72.3％ vs.35.8％,x2 =14.740,P =0.000).The nucleated cells count,protein quantity and their positive rates in EVT1 infected group were higher than those in control group (Z =-9.458 and-6.591,P=0.000; x2=105.421 and 10.932,P =0.000 and 0.001).Conclusion The symptoms of nervous system damage and abnormal CSF examination were more serious in HFMD induced by EV71 infection,and in EV71 infected patients the incidence of limb shaking is correlated with nucleated cell count in CSF.

Objective:This study was conducted to evaluate and discuss the curative effect and toxicity of gemcitabine, navel-bine, and therarubicin (GNT) regimen for patients with refractory or relapsed T-cell lymphoma (TCL). Methods:A total of 69 patients with refractory or relapsed TCL treated with GNT were enrolled. The treatment protocol was set as follows:800 mg/m2 gemcitabine ad-ministered at 1 and 8 d;25 mg/m2 navelbine administered at 1 d;and 20 mg/m2 therarubicin administered at 1 d. This protocol was re-peated every three weeks. The median cycle was 4 (range:2 to 6). Results:The overall response rate was 65.2%and the achieved com-plete remission was 29.0%. Hematology toxicities were the main adverse reactions observed in all of the patients. The incidence rates of grades 1 and 2 toxicity in leukopenia or neutropenia, anemia, and thrombocytopenia were 50.7%, 33.3%, and 26.1%, respectively. Grades 3 and 4 treatment-associated toxicities were detected in 23.1%of the responding patients. One-, three-, and five-year estimated overall survival (OS) of the whole cohort were 71.7%, 47.3%, and 32.4%, respectively. The median OS was 36 months. Conclusion:GNT was effective and suitable for patients with refractory or relapsed TCL.
