MyT1-positive cells in the cortex and hippocampal field CA 1 of epileptic rats were determined by immunofluorescence histochemistry.Results Compared with the control group, the number of MyT1-positive cells within the cortex and hippocampal field CA 1 of epileptic rats decreased significantly at 1 day after seizure ( P

Objective To investigate the protective effect of topiramate(TPM) on neuronal apoptosis in rats with acute seizures.Methods We treated the PTZ-induced seizure rats with TPM at 80mg/(kg?d)(high-dose group) and 40mg/(kg?d)(middle-dose group) or physiological saline(control group) for 2 weeks.Neuronal apoptosis in CA_1 and CA_3 regions in hippocampus was identified by terminal deoxynucletidyl transferase-mediated dUTP-biotin in situ nick end labeling(TUNEL) assay.Results Two weeks following seizures,TUNEL-positive neurons were detected in CA_1 and CA_3 regions each group.The numbers of TUNEL-positive neurons in CA_1 and CA_3 of control group were(35.83?)4.58 and(36.83?)3.83,(23.50?)2.81 and(25.50?)3.72 of high-dose TPM group,(31.52?)3.43 and(32.35?)4.69 of middle-dose TPM group.There was a very significant difference between high-dose TPM group and control group(all(P)0.05).Conclusion High dose administration of TPM after experimental status epilepticus may attenuate seizure-induced hippocampal neuronal injury.

Abstract: Objective　To analyze the drug resistance of Staphylococcus aureus in blood samples of children and adults from 50 hospitals in Shandong Province, and to understand the drug sensitivity characteristics of Staphylococcus aureus bloodstream infection (BSI), so as to provide reference for clinical experience. Methods　The distribution and drug resistance of Staphylococcus aureus isolated from blood samples from 50 hospitals in Shandong province from 2017 to 2020 were analyzed based on the Cooperative Research Network of Pediatric Bacterial and Fungal Resistance Monitoring in Shandong Province. Meanwhile, the drug sensitivity characteristics of Staphylococcus aureus were divided into children group (<14 years old) and adult group (≥14 years old). The data were analyzed by Whonet 5.6 and SPSS 22.0 with reference to CLSI 2021 M100 document standard judgment results. Results　A total of 3 661 Staphylococcus aureus strains were collected from 50 medical institutions in Shandong Province, including 675 in 2017, 870 in 2018, 1 080 in 2019, and 1 036 in 2020. The drug resistance rates of multiple antibiotics in blood culture methicillin-resistant Staphylococcus aureus (MRSA) group and methicillin-sensitive Staphylococcus aureus (MSSA) group were significantly different (P<0.05). There were significant differences in antibiotic resistance rates between adult group and children group (P<0.05). The overall detection rate of MRSA was 27.5%, and no staphylococcus aureus strains resistant to vancomycin, linezolid and tigecycline were found. Conclusion　The detection rate of MRSA strains decreased continuously and increased by 2020. The detection rate of MRSA in adult group was lower than that in children group, suggesting that we should pay attention to the monitoring of bacterial resistance in children group, to the management of multiple resistant bacteria and rational use of antibacterial drugs.

Purpose To explore the clinical value of131I-whole body scan (131I-WBS) and 18F-FDG PET/CT on the metastatic management of patients with differentiated thyroid cancer (DTC) after operation.Materials and Methods Serum thyroglobulin (Tg) of 27 patients after DTC surgery was measured one day before131I therapy, and the patients underwent131I-WBS on 3-5 days after131I therapy. According to the results of Tg and 131I-WBS, all the patients were divided into 4 types as follows: type I: Tg (+),131I-WBS (-); type II: Tg (+),131I-WBS (+); type III: Tg (-),131I-WBS (+); and type IV: Tg (-), 131I-WBS (-). Then the patients received18F-FDG PET/CT scan within a week after 131I-WBS. The results of131I-WBS and18F-FDG PET/CT scan were analyzed according to histopathologic findings or clinical and imaging follow-up of at least 6 months as diagnosis standard.Results The examinations uncovered that metastasis occurred in 52 lesions of 22 cases out of the 27 cases.131I-WBS revealed 24 metastatic lesions (46.2%) in 8 cases (36.4%), and18F-FDG PET/CT showed 35 metastatic lesions (67.3%) in 15 cases (68.2%), the difference with statistic significance (χ2=4.46 and 4.74,P<0.05). Metastasis were confirmed in 13 type I cases (100.0%); 5 type II cases (100.0%); 3 type III cases (100.0%) and 1 type IV case (16.7%), respectively. The rate of detecting metastasis by 18F-FDG PET/CT was 100.0% in type I, 20.0% in type II, 0% in type III respectively, the difference with statistic significance (χ2=9.14 and 10.11,P<0.05); and 100.0% in type IV, the difference without statistic significance (χ2=1.25,P>0.05). Based on that, therapeutic plans were modified for 13 patients with type I metastasis and 1 patient with type IV metastasis.Conclusion131I-WBS and18F-FDG PET/CT are complementary for detecting metastatic lesion and help to decide the following treatment of DTC patients after surgery. Moreover,18F-FDG PET/CT shows advantages in detecting metastatic lesion in Tg-positive and negative131I-WBS type of DTC patients after surgery, thus can provide an important clinical guidance for this type of patients.
