		                        			Objective:To discuss the effect of downregulating the proline-rich protein 11(PRR11)expression on drug resistance of the esophageal cancer drug resistant cells,and to clarify the related mechanism.Methods:The drug resistant cells EC9706/cisplatin(DDP)were established by incrementally stimulating the human esophageal cancer EC9706 cells with the increasing concentrations of DDP.The drug sensitivity of the EC9706/DDP cells was detected by MTT assay;the expression levels of PRR11 mRNA and protein in the EC9706/DDP cells and their parent EC9706 cells were detected by real-time fluorescence quantitative PCR(RT-qPCR)and Western blotting methods.The EC9706/DDP cells were divided into control group,sh-NC group(infected with sh-NC),sh-PRR11 group(infected with sh-PRR11),sh-NC+DDP group(infected with sh-NC and treated with 4 mg·L-1 DDP),and sh-PRR11+DDP group(infected with sh-PRR11 and treated with 4 mg·L-1 DDP).The expression levels of PRR11 mRNA in the cells in various groups were detected by RT-qPCR method;the expression levels of PRR11,phosphoinositide 3-kinase(PI3K)p110α,protein kinase B(AKT),phosphorylated AKT(p-AKT),P-glycoprotein(P-gp),and multidrug resistance-associated protein 1(MRP1)proteins in the cells in various groups were detected by Western blotting method;the apoptotic rates of the cells in various groups were detected by flow cytometry.Results:The DDP-resistant cell line EC9706/DDP was successfully obtained,and the drug resistance index was 7.23±0.86.Compared with the EC9706 cells,the expression levels of PRR11 mRNA and protein in the EC9706/DDP cells were increased(P<0.05).Compared with control and sh-NC groups,the expression levels of PRR11 mRNA and protein in the cells in sh-PRR11 group were decreased(P<0.05),and the 50%inhibitory concentration(IC50)of DDP was decreased(P<0.05).Compared with sh-NC group,the expression levels of PI3K p110α,p-AKT,P-gp,and MRP1 proteins in the cells in sh-NC+DDP and sh-PRR11 groups were decreased(P<0.05),and the apoptotic rate of the cells was increased(P<0.05).Compared with sh-NC+DDP group and sh-PRR11 group,the expression levels of PI3K p110α,p-AKT,P-gp,and MRP1 proteins in the cells in sh-PRR11+ DDP group were increased(P<0.05),and the apoptotic rate of the cells was increased(P<0.05).Conclusion:Downregulating the expression of PRR11 gene in the drug resistant EC9706/DDP cells can inhibit the expressions of drug resistance-related proteins,reverse the resistance to DDP,and induce the apoptosis;its mechanism may be related to the inhibition of activation of the PI3K/AKT signaling pathway.

		                        			Objective:To summarize the clinical and EEG characteristics of children with self-limited epilepsy with centrotemporal spikes (SeLECTS), and explore the risk factors for comorbid attention-deficit hyperactivity disorder (ADHD).Methods:Demographic and medical history data, seizure characteristics, EEG data, and treatment information of 122 children with SeLECTS admitted to Department of Neurology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from July 2020 to March 2024 were collected. Based on Swanson, Nolan and Pelham-IV Rating Scale (SNAP-IV) results, these patients were divided into comorbid ADHD group ( n=64) and non-ADHD group ( n=58); the clinical data and EEG characteristics (location and lateralization of discharges, synchronicity of bilateral discharges, period of discharges, spike wave frequency and special waveforms) of the patients between the 2 groups were compared to analyze the risk factors for comorbid ADHD. Results:(1) In 122 SeLECTS children, 70 (57.38%) were males and 52 (42.62%) were females; onset age was (7.50±1.98) years (3-12 years); 72.95% (89/122) patients had seizures only within 1 h after falling asleep, 9.84% (12/122) had seizures only 1-2 h before awakening in the morning, 9.84% (12/122) had seizures both after falling asleep and before awakening in the morning; duration of a single episode was (116.60±89.68) seconds (10-600 seconds). (2) Background activity in EEG showed no obvious abnormalities; the discharges were located in the central temporal region in 93.20% (96/103) patients and in the central temporal region and other brain regions (including frontal region, anterior head, bilateral occipital midline and bilateral cerebral hemispheres) in 6.80% (7/103) patients; among 69 patients whose overnight EEG recording was obtained, the spike frequency was 35.00 (20.67, 55.00) times/min (0.33-86.33 times/min). (3) Among 120 patients who accepted drug treatment, 87 (72.50%) received monotherapy, including valproic acid ( n=30, 34.48%), oxcarbazepine ( n=21, 24.14%), lacosamide ( n=17, 19.54%), levetiracetam ( n=17, 19.54%), perampanel ( n=1, 1.15%), and lamotrigine ( n=1, 1.15%); 33 (27.50%) received combination therapy with two or more drugs. (4) The comorbid ADHD group had statistically younger age of onset, longer duration of a single episode, higher proportion of seizures both after falling asleep and before awakening, and higher spike wave frequency in EEG than the non-ADHD group ( P<0.05). Conclusions:SeLECTS patients generally have onset age of 3-12 years, seizures within 1 h after falling asleep or 1-2 h before awakening, normal EEG background activity, and epileptiform discharges mostly located in the centrotemporal area, which are different from other types of epilepsy. SeLECTS patients with young age of onset, long duration of a single episode, seizures both after falling asleep and before awakening and high spike wave frequency in EEG trend to develop ADHD comorbidity.

		                        			 Objective: To investigate the expressionof proline-rich protein 11 (PRR11) in esophageal carcinoma (EC) tissues and to study it’s effect on the proliferation and metastasis of human EC TE-2 cells in vitro. Methods: Eighty patients were pathologically diagnosed with EC the Department of Thoracic Surgery of the Second Affiliated Hospital of Zhengzhou University from October 2016 to October 2018, and their surgically resected cancer tissues and corresponding para-cancerous tissues were collected for this study. qPCR was used to detect the expression of PRR11 mRNAin tissues or cells. Log-rank Test was used to analyzethe relationship between the expression of PRR11 in EC tissues and general data, histological type, lymphatic metastasis, depth of invasion and TNM stageof the EC patients. Kaplan-Meierplot was used to analyze the association between PRR11 mRNA and patients’prognosis. TE-2 cells were transfected with lentivirus shRNA to construct cell line with PRR11 knockout and corresponding control cell lines, as shPRR11#1, shPRR11#2 and control group. qPCR and WB assays were used to verify the mRNA and protein expressions of PRR11 in cell lines respectively. MTT was used to examine the proliferation of transfected cells, and Transwell experiments were used to detect cell invasion and migration. Results: The expression of PRR11 mRNA in EC was higher than that in para-cancer tissues (P<0.05). There was significant correlation between PRR11 over-expression and histological type, lymphatic metastasis, depth of invasion and TNM stage(all P <0.05), and high PRR11 expression was significantly related with the poor prognosis of EC patients (P<0.05). The mRNA and protein expressions of PRR11 in cells of shPRR11#1 and shPRR11#2 groups were significantly lower than those in control group (all P <0.05). MTT assay showed that the proliferation of cells in shPRR11#1 and shPRR11#2 groups was significantly lower than that in the control group (P<0.05 or P<0.01). The results of Transwell invasion and migration assays showed that the average number of cells with in each field of viewin shPRR11#1 and shPRR11#2 groups was significantly lower than that in the control group (P<0.01). Conclusion: PRR11 is over-expressed in EC tissues and PRR11 over-expression is closely related to the occurrence, progression and prognosis of esophageal cancer. In vitro experiments have also demonstrated that knockdown of PRR11 can inhibit the proliferation, invasion and migration of EC. PRR11 can be used as a potential molecule marker and drug targets for EC.

		                        			Different antiepileptic drugs (AEDs) may cause similar adverse effects, one of which is diplopia. However, the AEDs causing diplopia and the dose-response effect of each drug remains uncertain. In this study, we compared several second-generation AEDs to find out whether they would contribute to the risk of diplopia and their effect-causing dose. A meta-analysis was performed on 19 studies in agreement with our inclusion criteria. The results showed that eight commonly used second-generation AEDs (gabapentin, levetiracetam, oxcarbazepine, lamotrigine, pregabalin, topiramate, vigabatrin and zonisamide) could cause diplopia. The reported odds ratios (ORs) ranged from 1.406 to 7.996. Ranking risks from the highest to the lowest ORs of the eight AEDs of any dose resulted in the following order: use of oxcarbazepine (7.996), levetiracetam (7.472), lamotrigine (5.258), vigabatrin (3.562), pregabalin (3.048), topiramate (2.660), gabapentin (1.966), zonisamide (1.406). Taking into account the ORs above, we can conclude that second-generation AEDs of any dose may cause diplopia. However, the levetiracetam-caused diplopia needs to be further studied according to the data (OR, 7.472; 95% confidence interval, 0.375-148.772). These findings ask for better concerns about patients' quality of life when giving antiepileptic treatments.

		                        			Objective To clinically analyze the frequent stroke localizations of moyamoya disease in order to improve our cognition toward it and reduce missed diagnosis. Methods All 32 patients were prospectively analyzed over the past 10 years in our hospital. Results The ratio of female to male was 1.28 and their age of onset ranged from 7 to 47 years old. Mean age of 5 ischemic stroke patients (15.6%) was 24 and mean age of 21 haemorrhagic stroke patients (65.6%) was 33 while mean age of 6 mixed type stroke patients (18. 8% ) was 32. The frequent ischemic stroke localizations were frontoparietal lobe (60%),temporo-occipital lobe (20%), and periventricular zone (20%). The frequent haemorrhagic stroke iocalizations were periventricular zone (42.8%), ventricle (39.2%), temporo-occipital lobe (10. 8%) and subarachnoid space (7.2%). No cerebellum and brain stem stroke occurred. Conclusion Adult patients usually develop intracranial hemorrhage. Moyamoya disease should be considered severely when adult patients develop periventricular and ventricular intracranial hemorrhage, frontoparietal cerebral infarction or adolescent patients develop ischemic stroke, especially companied with epilepsy.
