Objective:To compare the difference of epileptiform discharges detection in patients with epilepsy between the 25 electrodes electroencephalogram (EEG) system proposed by the International Federation of Clinical Neurophysiology in 2017 and the previous 19 electrodes EEG system.Methods:Patients suspected of epilepsy or with confirmed epilepsy who need a follow-up EEG were collected in Zhongshan Hospital, Fudan University from March 2018 to November 2019, and conventional video-EEG recording was performed on all patients for two hours with the standard 25 electrodes EEG system. Two neurophysiologists reviewed the recordings blindly using the 19 electrodes system and the 25 electrodes system, marking the epileptiform discharges and their amplitudes. Finally, the data were statistically analyzed.Results:A total of 403 patients were included in the study, in which 263 cases were diagnosed as epilepsy, including 129 cases of generalized epilepsy, 115 cases of temporal lobe epilepsy, 13 cases of frontal lobe epilepsy, two cases of parietal lobe epilepsy and four cases of occipital lobe epilepsy. In 115 temporal lobe epilepsy patients, 76 (66.09%) and 100 (86.96%) records were detected epileptiform discharges by the 19 or 25 electrodes EEG system respectively, and the difference was statistically significant (χ2=13.939, P<0.001). While in patients with non-temporal lobe epilepsy, there was not statistically significant difference between the two systems. In 76 patients whose temporal epileptiform discharges were detected by the two systems, the amplitudes of epileptiform discharges in the newly-added inferior temporal electrodes (F9/F10, T9/T10, P9/P10) and the original temporal electrodes (F7/F8, T7/T8, P7/P8) were (61.53±22.64) μV and (48.25±20.90) μV, respectively, with statistically significant difference between the two groups ( t=5.486, P<0.001). In patients with abnormal [79.59% (39/49) vs 61.22% (30/49), χ2=3.967, P=0.046] and normal [95.45% (42/44) vs 70.45% (31/44), χ2=9.724, P=0.003] imaging, the ability of the 25 electrodes EEG system to detect epileptiform discharges was higher than that of the 19 electrodes EEG system. Conclusion:The 25 electrodes EEG system can significantly improve the detection ability of temporal epileptiform discharges in patients with epilepsy, which is recommended for regular use to increase the detection ability of temporal area abnormal wave and assist the diagnosis and treatment of epilepsy.

Objective To comprehensively evaluate the clinical efficacy of hemoperfusion (HP) combined with continuous veno-venous hemofiltration (CVVH) on acute paraquat poisoning (APP).Methods Literatures of Chinese and English randomized controlled trials (RCTs), case control and cohort study on HP combined with CVVH in the treatment of APP from the PubMed, Embase, Wanfang, and CNKI up to November 2017 were enrolled (the subjects were > 16 years old). The obtained literatures were strictly screened and evaluated in quality, and data such as mortality, the life time of dead patients, inefficiency rate, incidence of multiple organ dysfunction syndrome (MODS) and acute respiratory distress syndrome (ARDS) were extracted. Meta-analysis was performed by RevMan 5.3. Results Twenty-one studies were included with 2222 subjects, among whom 976 subjects were in HP combined with CVVH group (experimental group) and 1246 subjects in HP group (control group). Compared with control group, the mortality in experimental group were significantly decreased [43.77% (362/827) vs. 55.26% (604/1093), odds ratio (OR) =0.68, 95% confidential interval (95%CI) = 0.56-0.82,P = 0.0001], the life time of death patients was significantly prolonged [mean difference (MD) = 4.63, 95%CI = 2.60-6.66,P < 0.00001], incidence of MODS [25.93% (70/270) vs. 55.36% (155/280),OR = 0.26, 95%CI = 0.14-0.49,P< 0.0001], and incidence of ARDS [30.37% (82/270) vs. 51.07%(143/280),OR = 0.42, 95%CI = 0.30-0.61,P < 0.00001], and inefficiency rate [8.72% (13/149) vs. 34.64% (53/153),OR=0.17, 95%CI = 0.09-0.34, P < 0.00001] were significantly reduced. Funnel chart showed that except the publication bias of mortality rate, there were less publication bias about other indicators among studies.Conclusion HP combined with CVVH can significantly reduce the mortality of patients with APP compared with HP alone on the whole, prolong the life time and reduce the occurrence of MODS and ARDS, thus improving the treatment efficiency.

Objective:To summarize the correlation between anterior pituitary function and tumor size in patients with different hormone-secreting pituitary adenomas.Methods:This was a retrospective case series study. The clinical data of 1 946 patients with pituitary adenoma hospitalized in the First Medical Center of Chinese PLA General Hospital from January 1, 2005, to December 31, 2020, were collected. The correlation between tumor size and anterior pituitary hormone levels was analyzed using Spearman rank correlation analysis in different types of pituitary adenomas.Results:The median age of the 1 946 patients was 45.1 years, of which 857 (44.0%) were men. The maximum tumor diameter of the patients [ M ( Q1, Q3)] was 22 (14, 30) mm. Tumor size in nonfunctioning adenomas ( n=1 191) was negatively correlated with adrenocorticotropic hormone (ACTH) ( r=-0.11, P<0.001), growth hormone ( r=-0.13, P<0.001), and luteinizing hormone (men: r=-0.26, P<0.001, women: r=-0.31, all P<0.001). The tumor size of somatotropic adenomas ( n=297) was positively correlated with growth hormone ( r=0.46, P<0.001), but negatively correlated with male testosterone ( r=-0.41, P<0.001). The tumor size of ACTH-secreting pituitary adenomas ( n=155) was positively correlated with the ACTH level at 8∶00 AM ( r=0.25, P<0.001); however, no correlation was found with cortisol at 8∶00 AM ( P>0.05). The tumor size of prolactinomas ( n=303) was positively correlated with the prolactin level (men: r=0.34, P=0.001; women: r=0.13, P=0.070). Conclusions:The correlation between the function of the anterior pituitary and size of the tumor depends on the cellular origin of the pituitary adenoma and specific type of hormone secretion. In somatotroph adenomas, ACTH-secreting pituitary adenomas, and prolactinomas, there is a positive correlation between tumor size and level of hormones secreted by the corresponding tumors. In patients with nonfunctioning adenomas, the tumor size was negatively correlated with the hormone levels of the pituitary-adrenal and pituitary-growth hormone axes.

Objective:To analyze the construction and operation of the 19th Hangzhou Asian Games designated hospitals, and to discuss the medical emergency security work of large-scale sports events, so as to provide references for the planning of designated hospitals in future large-scale sports events.Methods:Retrospective analysis was made on the establishment principles, requirements, selection of medical support personnel, and training exercises of the designated hospitals, focusing on the key links such as organizational system, staffing, designated areas, and drug management.Results:Total of 40 designated hospitals have successfully completed the task of medical security by rebuilding the medical security area of the Asian Games, elevating the process, equipping facilities, and strengthening staff training. During the Asian Games, 349 people were transferred to designated hospitals by ambulance, 54 people were hospitalized, 19 people underwent surgery, and 1022 people went to designated hospitals by themselves.Conclusion:The construction of the designated hospitals during the 19th Hangzhou Asian Games was of high quality, efficient and smooth operation. It is suggested that efforts should be made in the reconstruction of the medical security area for the Asian Games to be "relatively independent". The treatment process of self-visiting patients should be fully considered and the flat urgent emergency response mechanism needs to be established.
