Objective To investigate the efficacy and safety of Levertiracetam (LEV) in treating the neonates with intractable seizure, those who had under gone failed Phenobarbital (PB) treatment previously switched to or added LEV treatment currently.Methods Totally 14 neonates,designed as intractable seizure by clinical data and video electroencephalography(VEEG) and failed to PB treatment were enrolled in the study, and all neonates were switched to LEV or LEV + PB treatment.The initial loading dose of LEV was 30 mg/kg, followed by 15 mg/kg twice a day if symptoms were controlled 8-12 h,if not, followed by 30 mg/kg once.All neonates were switched to LEV monotherapy after the symptoms were controlled 48-72 h,if the symptoms could not be controlled by combined therapy of PB and LEV after 72 h, other therapies were administered.Electrocardiogram breath synchronous monitoring was performed during the first 72 h treatment.VEEG was performed during 1-3 months follow-up.Results (1) The symptoms of 8 (57.14％) out of 14 cases were completely controlled,2 neonates(14.29％) reduced seizure more than 50％ ,4 neonates(28.57％) failed to LEV or LEV + PB treatment,as a result,all of those neonates were switched to other treatments.(2) No drug adverse effect was observed.(3) One neonate died of hypoxic-ischemic encephalopathy combined with multiple organ failure during follow-up period, 7 cases were seizure-free with normal VEEG, 5 cases were switched to or added other antiepileptic drugs because of uncontrolled symptoms, and one neonate discontinued the follow-ups.Conclusions The high efficiency and safety of LEV for the treatment of the newborn seizures were proved by small samples of patients.And currently there is no evidence to prove PB might increase neuronal excessive apoptosis of the brain and the cognitive impairment, and more clinical researches are needed to promote LEV as a gleam of rescue medications of neonatal seizure as soon as possible.

Aim To investigate the role of miR-125 b and its DNA methylation in homocysteine ( Hcy )-in-duced vascular smooth muscle cells( VSMCs) prolifera-tion. Methods VSMCs were stimulated with 0,50, 100, 200, 500 μmol · L-1 Hcy respectively. Then qRT-PCR was used to detect the mRNA levels of miR-125b,and nested-touchdown methylation-specific PCR ( ntMS-PCR) was used to detect the methylation levels of miR-125b. VSMCs were transfected with miR-125b precursor or the inhibitor of miR-125b ,then 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyl tetrazolium bromide ( MTT ) assay was used to reflect the proliferation of VSMCs. The distribution of CpG islands of miR-125b promoter region was analyzed by bioinformatics meth-ods. VSMCs were stimulated with 100 μmol·L-1 Hcy and transfected with or without DNA methylation inhib-itors 5-nitrogen impurity cytidine ( AZC) , then the ex-pression of miR-125b was detected by qRT-PCR. Re-sults The mRNA levels of miR-125 b were decreased in 100,200,500 μmol·L-1 Hcy group compared with 0 μmol·L-1 Hcy group. The precursor of miR-125b could inhibit the proliferation activity and the inhibitor of miR-125 b could increase the proliferation activity of VSMCs cells. Bioinformatics analysis indicated that MiR-125 b promoter region had a CpG island whose length was 792 bp ( 1881-2672 ) . The miR-125 b pro-moter region methylation levels increased after Hcy in-tervention ( P <0. 01 ) . The expression level of miR-125 b increased after AZC intervention ( P <0. 05 ) . Conclusions ① Hcy promotes vascular smooth mus-cle cell proliferation maybe by down-regulating the ex-pression of miR-125b. ② Hcy down-regulates the ex-pression of miR-125 maybe by up-regulating the methy-lation levels of miR-125b promoter region.

Objective:To investigate the current status of primiparas′ postpartum fatigue and paternal involvement, and to explore the relationship between primiparas′ postpartum fatigue and paternal involvement, and to provide reference basis for developing targeted intervention measures to alleviate postpartum fatigue of primiparas.Methods:A cross-sectional survey was conducted on 347 primiparas from Affiliated Hospital of Yangzhou University, Yangzhou Maternal and Child Health Care Hospital from September to December 2020 by convenience sampling. The survey instruments included the general information questionnaire, the Parenting Alliance Inventory (PAI), and the Postpartum Fatigue Scale (PFS).Results:The total score of PAI was (86.51 ± 12.07) points, and the level of paternal involvement was high. The total score of PFS was (16.68 ± 4.12) points. 95.97% (333/347) of primiparas had varying degrees of postpartum fatigue. There was a significant negative correlation between paternal involvement and primiparas′ postpartum fatigue ( r=-0.327, P<0.01). The results of multiple stratified regression analysis showed that paternal involvement was included in the influencing factor model of primiparas′ postpartum fatigue, which could independently explain 9.7% variation of primiparas′ postpartum fatigue. Conclusions:The higher level of paternal involvement could predict the lower level of primiparas′ postpartum fatigue. Medical staff should pay attention to the participation level of the spouses of primiparas in childcare, and improve the participation level of the spouses of primiparas in scientific ways to alleviate the postpartum fatigue of primiparas.

【Objective】 To study how blood donation intention among college students was influenced by publicity information (framework effect), individual characteristic (altruistic personality) and micro-system of the social ecological systems(organization trust) through the viewpoints of social psychology, sociology and behavioral economics, aiming at providing new strategies for donors recruitment in colleges. 【Methods】 A total of 1 225 questionnaires were distributed to four universities in Xiamen and Quanzhou, Fujian Province from June 2021 to December 2021, with blood donation publicity information included, to investigate the blood donation intention, altruistic personality, organization trust and demographic characteristics. 【Results】 A total of 99.18%(1 215/1 225)of the collected questionnaires were valid.The average score of blood donation intention was (76.40 ± 24.31) (the range of value was 0-100). Multiple linear regression showed that altruistic personality and organization trust were positively associated with donation intention (P<0.05). Altruistic personality and organization trust had a significant interaction; with the increase of organization trust, the correlation between altruistic personality and donation intention would decrease (P<0.05). In addition, the publicity information had significant frame effect on blood donation intention when other variables in the regression model were controlled (P<0.05). Compared to the negative framework, the positive framework can promote the donation intention better. 【Conclusion】 When recruiting potential blood donors among college students, positive image of blood centers is conductive to promote organization trust therefore promote donation intention.The effective use of framework effect to boost blood donation intention might improve the efficiency of donor recruitment to a certain extent.
