BACKGROUND:At present, researches about attention mainly concentrate on the relationship between attention and other psychological phenomena, but studies concerning different types of attention itself (sustained attention versus selective attention) are few. OBJECTIVE:To investigate the brain mechanisms of sustained and selective attentions which have different roles in the cognitive process. METHODS:Event-related potentials (ERPs) were measured when 18 col ege students’ participants (half male and half female) were performing selective and sustained attention tasks. The program was written in E-Prime and displayed on a computer, and the experimental task was adapted from Karl et al. reported experimental paradigm, including selective attention and sustained attention tasks. The time of fixation point given was 500 ms, and the time of three randomly abreast pictures given was 300 ms. Al the participants were asked to make rapid and accurate response as much as possible. RESULTS AND CONCLUSION:The ERPs elicited by the two attention tasks were different in the aspects of time process, wave crest and latency. The brain regions activated by the sustained attention were wider than those by selective attention. The ERPs elicited by the sustained attention mainly presents as positive waves, whereas those elicited by the selective attention were reflected as both positive and negative waves. The EPRs elicited by the sustained attention were N100 and N250, but in the metaphase, selective attention elicited the P180. These may indicate that event choice appears in the middle stage of the task. Besides, the reversion of EPRs elicited by the two attention tasks in the anterior and posterior scalp is likely to be a generality of al attentions.

Objective:To summarize the drug interactions of haloperidol used in combination with the other drugs to provide refer-ence for safe, reasonable and effective use of haloperidol in clinics. Methods:By retrieving Micromedex? , Pubmed, CNKI and so on, the interactions between haloperidol and the other drugs were summarized and analyzed. Results:The effect of haloperidol was on do-pamine receptors, and haloperidol was mainly metabolized by hepatic cytochrome P450 ( CYP) enzymes. When haloperidol was com-bined with the other drugs, significant interactions of pharmacokinetics and pharmacodynamics were induced by affecting CYP enzymes or dopamine receptor. Conclusion:In clinical practice, the other drugs combined with haloperidol should be reasonable and careful to ensure safe, effective and rational drug use.

OBJECTIVE:To systematically review the effect of CYP2C19 genetic polymorphism on lansoprazole pharmacoki-netics,and provide evidence-based reference for clinical individualized medication of lansoprazole. METHODS:Retrieved from PubMed,EMBase,Web of science,Cochrane Library and CJFD,retrospective studies about the effect of CYP2C19 genetic poly-morphism on lansoprazole pharmacokinetics were collected,Meta-analysis was performed by Rev Man 5.2 software after data ex-tract and quality evaluation. RESULTS:Totally 11 retrospective studies were included,involving 200 patients. The gene type in-cluded homozygote express metabolizers (EM),heterozygous express metabolizers (HEM) and slow metabolizers (PM). Results of Meta-analysis showed CYP2C19 polymorphism significantly affected cmax,AUC,t1/2,tmax and CL/F. The cmax and AUC in group PM were higher than group HEM and group EM;CL/F in group EM was higher than group HEM and group PM;t1/2 in group PM was higher than group HEM and group EM,while there was no significant difference in the t1/2 between group HEM and group EM;tmax in HEM and group PM were higher than group EM,while there was no significant difference in the tmax between group PM and group HEM. CONCLUSIONS:CYP2C19 genetic polymorphism shows obvious effect on lansoprazole pharmacokinetics, which is the key factor for causing efficacy of lansoprazole and individual differences among adverse reactions,and clinic should take into account individualized dose regimen of lansoprazole.

Objective:To systematically review the qualitative research on male participation in traumatic childbirth experience, and to provide reference for promoting and improving the physical and mental health and paternity experience of expectant fathers.Methods:Qualitative research on male participation in traumatic childbirth experience published in databases of PubMed, Embase, Web of Science, Spring Link, the Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM) and Wanfang Database were searched from the establishment of the database to June 2022. The quality of literature was evaluated by the quality evaluation standard of Australian JBI Evidence-based Health Care Center, and the pooled integration method in Meta integration was used to integrate the results.Results:A total of 12 articles were included, and 51 main research results were extracted, which were further summarized into 10 categories, and 4 integrated results were formed: men had prominent negative emotional experience; men lack decision-making participation and communication with medical staff during traumatic childbirth; the impact of traumatic childbirth experience on men; perception and coping after traumatic childbirth.Conclusions:Medical staff should pay attention to the emotional experience of men participating in traumatic childbirth, meet their decision-making information needs in the process of accompanying delivery, identify negative emotions in time after delivery and provide help and support, strengthen the family-centered perinatal health service model, promote the physical and mental health of expectant fathers, and improve the family well-being.

Objective:To construct an outpatient counseling record sheet of breastfeeding based on Delphi method, so as to standardize the consultation process of breastfeeding clinics.Methods:Through literature analysis and discussion of the research group, the expert letter questionnaire was designed by themselves. From September to October 2020, two rounds of Delphi letter inquiries were conducted with 16 experts in Hangzhou to determine the outpatient counseling record sheet of breastfeeding.Results:The positive coefficients of two rounds of expert letter inquiries were 100%, the expert authority coefficients were respectively 0.93 and 0.95, and the Kendall's coefficient of concordance were 0.135-0.204 and 0.234-0.563 ( P< 0.05) . The final counseling record sheet constructed included 8 first-level items, 99 second-level items and 94 third-level items. Conclusions:Letter consulting experts have high enthusiasm, high degree of authority and good coordination. The breastfeeding clinic consultation record based on the Delphi method is highly scientific and practical, which can be applied to breastfeeding clinics in various maternal and infant medical institutions.

Objective:To compare the short-term efficacy and the safety of microwave ablation (MWA) and radiofrequency ablation (RFA) in the treatment of benign thyroid nodules (BTNs).Methods:This prospective randomized controlled trial, performed from December 2019 to September 2021, included 36 patients with solid or predominantly solid BTNs who met the eligibility criteria and provided written informed consent at the Nanjing sub-center (Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine). Patients were assigned to either the MWA group or the RFA group (18 patients in each group) at a ratio of 1∶1 using a block randomization design and allocation concealment using sealed envelope randomization. The independent-sample t-test and χ2 test were used to compare the volume reduction rates (VRRs), effective rates (VRRs≥50%), cosmetic scores, and complication rates at 1, 3, and 6 months after treatment between the two groups. Results:The clinical characteristics of the two groups of patients were comparable. After ablation, the nodule volume was significantly reduced in both groups. At 1, 3, and 6 months, there was no significant difference in the volume between the two groups (all P>0.05). At 3 months, the RFA group had a larger VRRs than that in the MWA group (62.08%±12.46% vs. 46.90%±23.16%, t=-2.45, P=0.021). However, at 1 and 6 months, no statistical significance was observed (both P>0.05). No significant difference was observed in the effective rates at the last follow-up (14/18 vs. 18/18, P=0.104). However, the RFA group had a lower cosmetic score than that in the MWA group (1.78±0.43 vs. 2.17±0.51, t=-2.47, P=0.019). There was no statistically significant difference in the complication rates between the two groups (all P>0.05). Conclusions:Both MWA and RFA were effective and safe treatments for BTNs, with no significant differences in short-term efficacy and safety. In addition, the RFA group showed slightly more favorable outcomes than the MWA group in terms of cosmetic improvement.
