Objective To investigate the clinical and electroencephalogram (EEG) features of patients with idiopathic generalized epilepsy in adults with phantom absences.Methods Six patients were referred to the clinic of epilepsy from April,2007 to December,2011.They all had clinical assessment,EEG,or video EEG confirming absences seizure.Results Six patients showed the following similar clinical-EEG features:(1) mild ictal impairment of consciousness associated with generalized 3.0-3.5 Hz spike and slow wave discharges; (2) late-onset generalized tonic-clonic seizures; (3) absence status epilepticus with or without secondary generalized tonic-clonic seizures; (4) generalized discharges were mostly seen in three types in the awaking stage:fragmented discharge (<4 s),brief discharge (4-10s) and long-time discharge (> 10 s).None of the patients had myoclonic jerks or photosensitivity.One patient' s mother had a history of generalized tonic clonic seizures.One patient had a history of children absence epilepsy and one patient had a history of febrile convulsion in the age of 1-3.Conclusion Idiopathic generalized epilepsy with phantom absences has distinct clinical and EEG features and may become a new idiopathic generalized epilepsy syndrome in adults.

Objective:To evaluate the efficacy and safety of quadruple therapy involving radiotherapy (RT), lenvatinib, anti-PD-1 antibody and GEMOX (oxaliplatin and gemcitabine) chemotherapy (quadruple therapy) in treatment cohort of patients with unresectable intrahepatic cholangiocarcinoma (ICC).Methods:The patients with recurrent, metastatic, or unresectable ICC underwent quadruple therapy at Zhongshan Hospital, Fudan University between September 2018 and May 2022 were selected. The data about efficacy and safety of quadruple therapy were collected in the hospital electronic medical record system. All patients were followed up regularly to obtain the long-term prognostic data until December 31, 2022. The efficacy, prognosis, and toxicity data were collected and analyzed.Results:A total of 41 patients were included in the analysis. After a median follow-up period of 15 months, disease progression was diagnosed in 36 patients (18 patients died), while 3 patients were lost to follow-up. The causes of death included liver failure induced by intrahepatic tumor progression ( n=6), distant metastases (lungs or brain, n=6), abdominal lymph node metastases ( n=3), cancer cachexia ( n=2), and unknown cause ( n=1). The median progression-free survival (PFS) was 11 months (95% CI: 9.2-12.8), and the median overall survival (OS) was 35 months (95% CI: 17.0-52.0). All patients experienced treatment-related adverse events (AEs) during the study treatment period. Of the 41 patients, 13 patients experienced at least once grade 3 or worse treatment-related AE, but all were manageable with symptomatic treatment. No treatment-related deaths were reported during the follow-up period. Conclusions:Radiotherapy (RT), lenvatinib, anti-PD-1 antibody and GEMOX in the treatment of unresectable ICC shows significant efficacy and good safety, which is worthy of clinical application.

Objective:To study the effects of radiotherapy and the prognostic factors in hepatocellular cancer (HCC) patients with cardiophrenic angle or superior diaphragmatic lymph nodes metastasis (LNM).Methods:We retrospectively analyzed 56 HCC patients with cardiophrenic angle or superior diaphragmatic LNM who were treated with or without external beam radiation therapy (EBRT) in Zhongshan Hospital of Fudan University from Jan 2010 to Aug 2020. Patients were divided into two groups according to whether they received radiotherapy, EBRT group and non-EBRT group, and each group had 28 patients. Radiation fields included or excluded primary tumor in EBRT group, and the cardiophrenic angle or superior diaphragmatic LNM did not receive any local treatment in non-EBRT group. The response rate, survival rate, local control rate, prognostic risk factors of the two groups were studied.Results:After EBRT, the partial response rate and complete response rate were 32.1%(9/28) and 32.1%(9/28). The median survival rate of EBRT group was 16.1 months (95% CI 9.00-23.21, RR=3.63) vs. 6.9 months (95% CI 4.63-8.77, RR=1.06) for the non-EBRT group, with statistically significant difference ( χ2=15.53, P<0.05). Cardiophrenic angle or superior diaphragmatic lymph nodes 1-year local control rate for EBRT group and non-EBRT group were 37.0% vs. 10.7%, with statistically significant difference ( χ2=5.28, P<0.05). Since diagnosis of cardiophrenic angle or superior diaphragmatic LNM, 4 patients (14.3%) in the EBRT group vs. 13 patients (46.4%) in the non-EBRT group had higher alpha-fetoprotein (AFP) level after 3 months compared with the AFP before EBRT ( χ2=6.84, P<0.05). Multivariate analysis showed that multiple intrahepatic tumors, maximal diameter of intrahepatic tumors >5 cm, AFP≥400 μg/L, no EBRT were poor prognostic factors. Conclusions:EBRT can prolong overall survival and improve the control rate of lymph node of HCC patients with cardiophrenic angle or superior diaphragmatic LNM. Patients with multiple intrahepatic tumors, maximal diameter of intrahepatic tumors >5 cm, AFP≥400 μg/L and no EBRT have poor prognosis.

Objective:To explore the effect of a new teaching mode, which includes bridge-in, outcome, pre-test, participation, post-test and summary (BOPPPS), on the online teaching of radiobiology related knowledge for cancer radiotherapy practitioners.Methods:Taking the cell survival curve, cell cycle and radiosensitivity as examples, the radiotherapy practitioners in multiple university-affiliated hospitals were organized to carry out a multicenter prospective randomized control study. All practitioners were randomly divided into BOPPPS group and control group. The courses for BOPPPS group were designed as an online classroom, consisting of pre-class preparation, online teaching and post-class stages. The online teaching stage included video viewing, basic knowledge learning, literature discussion, group discussion and others. The control group employed the traditional teaching mode. The χ2 test was used to compare the consistency of general conditions between the two groups, and nonparametric test was used to compare the differences in scores between two or more groups. Results:The score of the pre-class test was 58.56 ± 0.99. Post-class average score for BOPPPS group was 85.48±0.85 and for control group 77.79±1.10, with the former being higher 7.69 ( Z=5.31, P<0.001) than the latter. The average answer time was (296.62±15.40) s for BOPPPS group and (386.41±21.27) s for control group, with the former being shorter 89.79 s ( Z=3.34, P=0.001) than latter. Subgroup analysis shown that the scores of BOPPPS group were significantly rising, regardless of whether or not the students had studied radiobiology courses. Among the students who have not studied these courses, the scores were rising greatly. Moreover, From the analysis of different positions, it was found that both the scores of BOPPPS group and control group have risen, especially for doctors, deputy chief doctors, physicists and technicians. There were also statistically differences between different degrees, with significantly rise in scores for undergraduate and doctoral students ( Z=3.64, 4.18, P<0.001). Conclusions:The flexible application of BOPPPS teaching mode to the online education of such boring disciplines, like radiobiology, is of great significance to raise the theoretical basis of radiotherapy practitioners.
