Objective:To explore the electro-clinical characteristics of Jeavons syndrome complicated with non-convulsive status epilepticus (NCSE).Methods:Three patients of Jeavons syndrome complicated with NCSE during electroencephalogram (EEG) monitoring in the EEG Monitoring Center, Department of Neurology, Xijing Hospital in 2018 were studied and followed up.Results:Among the three patients, there are two female patients, one male patient, aged 12 to 24 years. Generalized spike-wave discharges and impaired consciousness were recorded during video-EEG monitoring, which lasted for 8 minutes to 6.5 hours and evolved in generalized tonic clonic seizure (GTCS), and did not recur after receiving correct anti-epileptic drugs.Conclusion:NCSE can also occur in Jeavons syndrome, and NCSE in patients with Jeavons syndrome ends with GTCS, suggesting that early detection and timely termination of NCSE in patients with Jeavons syndrome may avoid the occurrence of GTCS.

Exploding head syndrome(EHS)is a rare sensory parasomnia and rarely reported in China, leading to serious misdiagnosis, mistreatment, and unnecessary testing. A detailed collection of clinical symptoms and longterm polysomnography-electroencephalography monitoring is very important for diagnosis and differential diagnosis of EHS. We diagnosed a patient with EHS according to the International classification of sleep disorders, third edition diagnostic criteria. The electro-clinical feature of the patient and relevant references were analyzed in order to improve the understanding of EHS, meanwhile to prevent unnecessary testing and avoid misdiagnosis and mistreatment.

Ziziphi Spinosae Semen (ZSS), a traditional Chinese medicine, is used in clinics for the treatment ofinsomnia in China and other Asian countries. Herein, we described for the first time a comparative pharmacokinetics study of the six major compounds of ZSS in normal control (NC) and para-chlor-ophenylalanine (PCPA)-induced insomnia model (IM) rats that were orally administered the aqueous extract of ZSS. An ultra-high-performance liquid chromatography coupled with quadrupole orbitrap mass (UHPLC-Q-Orbitrap-MS) method was developed and validated for the simultaneous determination of coclaurine, magnoflorine, spinosin, 6'''-feruloylspinosin, jujuboside A (JuA), and jujuboside B (JuB) in ZSS in rat plasma. The established approach was successfully applied to a comparative pharmacokinetic study. The systemic exposures of spinosin and 6'''-feruloylspinosin were decreased in the IM group compared to the NC group, while plasma clearance (CL) was significantly increased. The Tmax values of JuA and JuB in IM rats were significantly lower than those in NC rats. The T1/2 of JuA in the IM group was significantly accelerated. The pharmacokinetic parameters of coclaurine and magnoflorine were not evidently affected between the two groups. These results indicate that the pathological state of insomnia altered the plasma pharmacokinetics of spinosin, 6'''-feruloylspinosin, JuA, and JuB in the ZSS aqueous extract, providing an experimental basis for the role of ZSS in insomnia treatment. The comparative pharmacokinetics-based UHPLC-Q-Orbitrap-MS using full-scan mode can therefore provide a reliable and suitable means for the screening of potentially effective substances applied as quality markers of ZSS.

Objective: To investigate the duration of Norovirus (NoV) shedding among infected school children during a NoV outbreak in a kindergarten,and to provide scientitic basis for epidemic prevention and control. Methods: Specimens and epidemiological data were collected from suspected cases, and specimens were detected using real-time RT-PCR to determine whether or not infecting with NoV. Specimens were collected every 3-7 days from NoV-infected children until specimens became negative for NoV. Results: A total of 14 suspected cases were reported, and 12 of them were infected with NoV. The average duration of NoV shedding was (26.58±17.94)d. The specimens among 9 from 12 Nov-infected cases were positive at 7 days, 8 NoV-intected cased remained positive at 14 days and 7 Non-infected cased at least 21 days. Conclusion Since NoV shedding duration among NoV-infected children tends to longer than their isolation time during outbreaks, reinforcement of hygiene practices among these school children is especially necessary to reduce the risk of virus secondary transmissions after their return to school.

Objective:To explore indications for replantation of proximal proper digital artery and establishing extrinsic arterial perfusion pressure in the treatment of special type of severed digits with avulsion over 12.0 hours of warm ischemia, and to analyse the factors that affected the survival rate of the replanted digits.Methods:From September 2014 to January 2022, 8 patients with severed digits and prolonged warm ischemia were treated by transposition of adjacent digital artery together with the technique of extrinsic arterial perfusion pressure in the Department of Wrist and Hand Surgery, the Orthopaedic Hospital in Sichuan Province. During the operation, the defected proximal proper digital artery was reconstructed and repaired with vein graft, one side of the digital artery was repaired with an inverted "Y" vein graft, and one side of "Y" vein was bridged and anastomosed to repair the original digital artery. On the other side, the adjacent proximal proper digital arteries were transpositioned and anastomosed to gain an extrinsic arterial perfusion pressure, which increased the distal haemodynamic and reconstituted the blood supply. Of the 8 patients (9 severed digits) : 1 had severed index and middle fingers, 2 had severed index fingers, 4 had severed thumbs and 1 had severed little finger. All the patients were males, aged 16-63 years old, at 37.6 years old in average. Warm ischemia time of the severed digits were 12.3-20.6 hours, with 17.4 hours in average. The survival rate of replanted digits was observed after surgery. Postoperative follow-ups were conducted through telephone or WeChat reviews.Results:Follow-up time was 6-26 months, at 8.3 months in average. Retrospective analysis was performed. Vascular compromises occurred in 3 patients 4 digits (arterial insufficiency in 1 digit, venous congestion in 3 digits), skin necrosis occurred in 1 patient (1 digit) and digit necrosis in 1 patient (1 digit). Overall, 8 of the 9 replanted digits survived. According to the Replantation Function Evaluation Standard of Hand Surgery Association of Chinese Medical Association, the digit function after replantation was evaluated at excellent in 6 digits, good in 1 digit and poor in 1 digit.Conclusion:For a severed digit with an ischemia time over 12.0 hours, the survival rate can be improved by transposition of an adjacent digital artery to provided extrinsic arterial perfusion pressure.

Standardized electroencephalography (EEG) electrode positions are essential for both clinical applications and research.The aim of the International Federation of Clinical Neurophysiology (IFCN) guideline is to update and expand the unifying nomenclature and standardized positioning for EEG scalp electrodes.Twenty percent and ten percent standard recordings do not cover the anterior and basal temporal lobes.Here,IFCN proposes a basic array of 25 electrodes including the inferior temporal chain,which should be used for all standard clinical recordings.Contrary to the established belief,the guideline suggests at least as many electrodes in young children as in adults.High-density scalp EEG arrays (64-256 electrodes) allow source imaging with even sub-lobar precision.In the future,nomenclature for high density electrodes arrays beyond the 10-10 system needs to be defined,to allow comparison and standardized recordings across centers.

Acute lymphoblastic leukemia(ALL)is the most common childhood malignancy.As an essential component of multiagent chemotherapy, asparaginase(ASP)has significantly improved the remission rate and event-free survival rate of children with ALL since its application in clinical practice.However, there are many adverse events due to ASP, including asparaginase-associated pancreatitis(AAP). The mechanisms behind and the risk factors predisposing AAP are unknown.This review summarizes the latest research progresses on AAP.

Objective:To investigate the effects of exercise prescription on quality of life in patients with pituitary adenomas after surgery.Methods:A total of 82 patients with pituitary adenomas who met the inclusion criteria from December 2017 to September 2018 were enrolled. The control group received routine nursing care. The intervention group was given exercise prescription on the first day after surgery and 3 months after discharge from hospital. Both groups of patients completed the Health Status Survey(SF-36) before and after the intervention.Results:Before the intervention, there was no significant difference in baseline date of patients between two groups( P>0.05). After intervention, the general health dimension score (53.03±11.30) of the control group was significantly higher than the score within the group before treatment ( Z value was -4.398, P<0.05). The physiological function (86.67±7.46), physical function (66.67±29.28), role-emotional (71.30±22.75), vitality (68.33±8.78), general health dimension (61.39±10.66) of the intervention group were significant higher than the score within the group before treatment ( Z values were -4.809--2.041, P<0.05) . After the intervention, the significant difference were found in role-physical, general health, vitality, social function(77.18±15.71) and physiological health dimensions (73.75±10.00) between the intervention and control group ( Z values were -3.122- -2.467, t value was 3.044, P<0.05). After the intervention, non-function patients′ physiological function (72.06±23.19), general health (60.59±10.75), vitality (69.71±10.23) and social function (81.04±10.22) were significantly higher than the control group ( Z values were -2.832- -2.059, P<0.05). Conclusion:Exercise prescription can improve the quality of life in patients with pituitary adenomas after surgery.
