Objective To explore the relationship between aural pre-attentive processing and non-rapid eye movement(NREM) sleep interictal epileptiform discharge (IED) in children with benign childhood epilepsy with central-temporal spikes (BECTS),in order to provide objective electrophysiological basis for early assessment of cognitive function lesion of BECTS children and intervention.Methods Twenty-nine children diagnosed as BECTS in the Second Affiliated Hospital of Xinxiang Medical University from February 2012 to November 2015 were selected,including 17 males and 12 females,and they were 4-14 years old with average age of (9.17 ±2.42) years,and the course of disease was 0.5-4.0 years.Twenty healthy children who had hospital routine check-up were selected as healthy control group,containing 14 males and 6 females,and they were 5-13 years old with average age of (8.55 ±3.09) years.Mismatch negativity (MMN) test was carried out in both groups,and the MMN amplitudes and latencies were analyzed.The long-term video electroencephalogram (VEEG) monitoring was conducted in the BECTS group to analyze the discharge phases (waking,sleep),locations and the IED indexes.The intergroup MMN indexes and the correlation between MMN and VEEG in the BECTS group were compared.Results The VEEG showed that the sleep structure of BECTS children did not change obviously.All children's epileptiform discharges were located in the Rolandic area,including 11 cases on the left side,8 cases on the right side,and 10 cases on both sides.Epilepsy discharge time:17 patients showed epileptiform discharges in sleep stages only and 12 patients showed epileptiform discharge in both sleep and waking stages.Epileptiform discharges of the 12 patients increased more significantly in sleep stage than thatin waking stage [(40.24 ± 25.15) times/min vs.(1.92 ± 1.38) times/rmin],and the difference was statistically significant (t =5.270,P =0.000).The sample IED index in stage 1 and 2 of NREM was (40.73 ± 10.69) times/min,in which 2 cases had IED indexes < 5 times/min,the IED indexes of 3 cases > 80 times/min who reached electrical status epilepticus during sleep,and others were 17.2-64.6 times/min.Clinical seizures in sleep stages were monitored in only 4 cases,which showed an electro-clinical segregation phenomenon from large quantities of sleep IED.The MMN amplitude was lower in the BECTS group than that in the healthy control group [(6.06 ± 1.89) μV vs.(7.28 ±1.64) μV],and the difference was statistically significant (t =2.346,P =0.025).Latency of BECTS group was longer than that in the healthy control group [(191.37 ±40.13) ms vs.(179.35 ±39.80) ms],but the difference was not statistically significant(t =1.037,P =0.355).Correlation analysis showed that the MMN amplitude was negatively related to discharge phases (r =-0.407,P < 0.05) and the IED indexes (r =-0.644,P < 0.01),and latency was positively related to the IED indexes (r =0.386,P < 0.05),while the other VEEG indexes were not correlated with MMN.Conclusions The BECTS children have aural pre-attentive processing disturbance,especially unconscious automatic processing ability impairment,which weakenattention switch action of automatic processing switching to focused attention processing and fail to filter irrelevant information effectively.Sleep IED is an important factor in impairing the formation and reinforcement of acoustic discrimination and memory trace,interfering the acquisition,processing,storage and matching of new information,which induces children pre-attentive processing disturbance.The MMN may discover the electrophysiological changes of children pre-attentive processing disturbance in early stage.

Objective To explore schizophrenic′s executive function and characteristics of event-related potential-P300 (ERP-P300) in a Go/Nogo paradigm in order to provide electrophysiological basis for schizophrenic′s executive function. Methods The Wisconsin card Sorting Tests (WCST) were conducted and ERP-P300s in a Go/Nogo paradigm (Go/NogoERP-P300) were determined in 58 schizophrenics and 30 healthy persons. Results The WCST score was poorer in research group than that in control group. ERP amplitudes lowered and latencies prolonged in Go-P3 and Nogo N2 and P3, and all differences had statistical significances (P < 0.05). But there were no differences in N1 of both tasks and Go-N2; Go-P3, Nogo-N2 and -P3 amplitude and latency were related to the WCST well (P < 0.05). Conclusion Schizophrenics have such lowered executive functions as attention and cognition conversion and reactive inhibition and could normally process task prophase merely , and Go/NogoERP-P300 may be one of electrophysiological methods reflecting schizophrenic′s executive function.

Objective To observe the changes of brainstem auditory evoked potential (BAEP) and lower limb short latency somatosensory evoked potential ( SLSEP) in acute carbon monoxide poisoning patients and explore the predictive value of BAEP and SLSEP for delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods Sixty-six acute CO poisoning patients was divided into a DEACMP group and a non-DEACMP group according to their symptoms. At the same time, 60 healthy subjects were included in the control group. BAEP and lower limb SLSEP dynamic testing were conducted at different time points. Results The abnormal rates in the first test of BAEP and lower limb SLSEP in the acute CO poisoning patients were 31.8% and 68.2% respectively.The BAEP results in the acute stage and later in the DEACMP group were comparable to those of the non-DEACMP group and the normal control group. Interpeak latency of Ⅰ-Ⅲ was not significantly different, but the remaining indices were significantly longer. Compared to the control group, the lower limb SLSEP readings in the acute DEACMP group and the non-DEACMP group were significantly longer. Compared to the non-DEACMP group and the control group, the SLSEP results of the DEACMP group were significantly extended. The specificity index of the BAEP predicted DEACMP up to 85.7% , significantly more than SLSEP testing. Conclusions Early detection of BAEP can help predict DEACMP. This finding should be promulgated and applied.

【Objective】 To conduct Rh blood group serological testing and third-generation sequencing(TGS) on 22 RhD variant voluntary blood donors in Chongqing and explore the phenotypic distribution and genotyping of RhD variants in Chongqing. 【Methods】 From January to August 2023, individuals who participated in blood donation in our blood center were selected as the study objects. RhD variant phenotype identification was performed using routine serological methods. Once the RhD variants were identified, tests on different antigenic epitopes of RhD were conducted using a D-screen assay kit. Furthermore, after the genomic DNA from 22 RhD variant blood samples was extracted, imbraided primers design and multi-segment amplification and splicing were used to sequence the full-length RHD gene for TGS. The RHD gene sequence was analyzed using SnapGene software. 【Results】 Among the 22 RhD variants, 8 were DVI type 3 (36.36%), with the main mutation of RHD-CE (3-6)-D hybrid allele. Six cases (27.27%) showed partial weak D15 type, with the main mutation of c.845G>A. There were 6 cases of Asia type Del (27.27%), with the main mutation of c.1227G>A. One case was weak D17 type with a mutation of c.340C>T and 1 case speculated to be partial D (c.491A>T, p. Asp164Val, missense mutation). 【Conclusion】 The most common RhD variant phenotype among blood donors in Chongqing is DVI type 3, and the full-length haplotype sequence of RHD variant alleles can be obtained by Pacific Bioscience single-molecule real-time sequencing(SMRT).

BACKGROUND:
Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion.
METHODS:
Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test).
RESULTS:
We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P <0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P <0.001). No statistically significant differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies.
CONCLUSION:
The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.
