ObjectiveTo investigate the expression of proapoptosis gene bad in intrahepatic cholangiocarcinoma (ICC) and its relationship to differentiation of the tumor.MethodsThe immunohistochemistry technique by Dako Envision system and rabbit antihuman bad polyclonal antibodies were adopted. The expression of bad was detected in 48 cases of ICC and 25 cases of control tissues.ResultsBad immunoreactivity in 48 cases of ICC was higher than that of bile duct epithelium in 25 cases of control tissues. And contrasted with 21 cases of well differentiated ICC, bad immunoreactivity was higher in 27 cases of middle and poor differentiated ICC.ConclusionThe expression of bad gene may be related to the differentiation of ICC.
Recently, sponsored by the Science Popularization Department of the China Anti Cancer Association, jointly organized by the Rehabilitation Branch of the China Anti Cancer Association and the Mijian Digital Cancer Patient Course Management Platform, and co-organized by the Science Popularization Special Committee of the China Anti Cancer Association, The "2022 White Paper on the Quality of Life of Chinese Lung Cancer Patients" has been officially released (herein after referred to as the "White Paper"), which mainly elaborates on the basic situation of Chinese lung cancer patients and the medical, social, and economic impacts caused by the disease. This article interprets the White Paper in order to help the public understand the real situation of lung cancer patients and provide important empirical evidence and valuable insights for the diagnosis, treatment, and rehabilitation of lung cancer in China.
ObjectiveAicardi and Goutières syndrome was first reported as a rare hereditary encephalopathy with white matter involvement in 1984. Typical clinical manifestations include severe mental motor development retardation or regression, pyramidal and extrapyramidal symptoms and signs, epilepsy, microcephaly and frostbite.MethodsTo collect a case of patient who presented with convulsions 14 days after birth without obvious inducement. The child was diagnosed as epilepsy in the local hospital and the symptoms improved after treatment with antiepileptic drugs. At 4 months, the child presented nods and clenched fists, and was diagnosed as infantile spasm. After Adrenocorticotrophic hormone and drug treatment, the symptoms gradually improved. Due to upper respiratory track infection, the child was aggravated at the age of 1 year and 2 months, and then diagnosed as Aicardi-Goutières syndrome by video EEG, skull MRI, fundus and gene screening.ResultsSurgery and treatment with antiepileptic drugs significantly improved the symptoms of the child, and the pathological biopsy of the brain tissue supported the previous diagnosis.ConclusionsThe report of this case will help to improve the clinician's diagnosis and treatment of Aicardi-Goutières syndrome.
ObjectiveTo investigate the efficacy and safety of Stereotactic electroencephalogram (SEEG)-guided Radiofrequency-thermocoagulation (RF-TC) in the treatment of refractory insular epilepsy in children.MethodsThe clinical data of 7 children with SEEG-confirmed insular epilepsy admitted to the Epilepsy Center of the Children’s Hospital Affiliated to Shandong University from January 2021 to May 2022, were retrospectively analyzed (3 males and 4 females; average age, 6.6±3.5 years). All patients underwent stage I pre-operative evaluation, and were implanted with SEEG electrodes for video EEG monitoring. The radiofrequency thermocoagulation contacts were determined according to SEEG and imaging results, and radiofrequency thermocoagulation was performed via electrode contacts. The patients were followed up at 3, 6, 12 and 18 months after operation by outpatient review or via telephone interview. The clinical efficacy was evaluated by Engel classification and complications were recorded. ResultsSix cases (6/7) were characterized by nocturnal seizures, and four cases (4/7) exhibited hypermotor or complex motor seizures. Three cases (3/7) showed focal ankylosis; only 1 patient had aura. All of the 7 cases showed interictal scalp EEG consistent with the side of surgery: 6 cases showed distribution in the perilateral fissure region, and 1 case showed confinement to the temporal region. In MRI, 4 cases showed negative signal, 2 cases showed unclear gray-white matter boundary, and 1 case showed thickening of the insular cortex. All of the 7 patients received electrode implantation and completed follow-up for over 6 months [6.0~22.0 (12.3±5.3) months]. At the last follow-up, 5 of the 7 children were seizure free (Engel class la), and 2 still had seizures after surgery, with no postoperative long-term complications.ConclusionChildren with insular epilepsy rarely show an aura, but have prominent motor symptoms, and the scalp electroencephalogram is mainly distributed in the perilateral fissured area. SEEG-guided RF-TC has good safety and efficacy in the treatment of drug‐resistant insular epilepsy.
