ObjectiveThe abnormal autophagy fluxis involved in the pathophysiological process of drug-resistance temporal lobe epilepsy (TLE).Hippocampal sclerosis (HS) is the main pathological type of drug-resistance TLE.Different subtypes of HS have various prognosis, etiology and pathophysiology.However, whether theabnormal block ofautophagy flux involved in this process has not been reported.This study proposed a preliminary comparison of autophagy fluxin typical and atypical HS to investigate the potential pathogenesis and drug-resistance mechanism of atypical HS. MethodsSurgical excision of hippocampal and temporal lobe epilepsy foci were performed in 17 patients with drug-resistance TLE.Patients were grouped according to the HS classification issued by International League Against Epilepsy in 2013.The distribution and expression of LC3B, beclin-1 and P62 were detected by immunohistochemistry and Western blot in each group. ResultsLC3B, beclin-1 and P62 are mainly expressed in neuronal cytoplasm, which is consistent with previous reports.Taking β-actin as internal reference, we found that LC3B and Beclin-1, the downstream products of autophagy flux, have increased significantly (P < 0.01) in the atypical HS group compared to typical HS group.However, the autophagy flux substrate P62 has no difference between the groups.This result suggested that compared with the typical HS group, atypical HS group had autophagy substrate accumulation and autophagy flux abnormal block.Besides, we found that glyceraldehycle-3-phosphate dehydrogenase(GAPDH) was significantly different between the two groups (P=0.003). ConclusionThere is abnormal phenomenon of autophagy flux in atypical HS, and GAPDH elevation may be involved in its mechanism, which might provide new targets and ideas for future treatment of atypical HS.
ObjectiveTo describe the status of epilepsy inpatients healthcare service in tertiary public hospitals in China by the data collected from the Hospital Quality Monitoring System.MethodsA population-based study was conducted with data of hospitalized patients collected from the Hospital Quality Monitoring System between 2015 and 2017. Diagnoses were identified by International Statistical Classification of Diseases and Related Health Problems 10th Revision codes for epilepsy (G40). The information of demographic characteristics, costs, payment methods, and discharge status were extracted and analyzed annually to make cross-sectional studies.ResultsA total of 329 241 hospitalized epilepsy patients from 585 tertiary public hospitals were identified. The average age of the patients was 31.74 and male patients accounted for 60.00% of the total. The proportion of patients covered by the national basic medical insurance in the three years was 50.15%, and that in the year 2015, 2016, and 2017 was 49.03%, 49.79%, and 51.80%, respectively; the proportion of patients with full self-payment was 30.40%. The average length of hospital stay was 6.65 d, the average cost for each stay was 7 985.53 yuan, the average self-payed cost for each stay was 3 979.62 yuan. In terms of the discharge way of the patients, 88.02% discharged following doctors’ advice, 0.40% were transferred to another hospital with doctors’ advice, and 6.59% discharged against doctors’ advice. The in-hospital mortality in the three years was 0.16%, and that in the year 2015, 2016, and 2017 was 0.19%, 0.16%, and 0.12%, respectively.ConclusionThe study shows that the in-hospital mortality rate of epilepsy inpatients in the tertiary public hospitals in China decreased gradually from 2015 to 2017, the coverage rate of national basic medical insurance increased year by year, and there is still room for further improvement.
