BackgroundMigrant children face many challenges in the process of social change and adaptation to a new environment， especially in school adaptation. Studies have shown that peer attachment plays a vital role in the social adaptation of children and adolescents， while psychological resilience and sense of security， as important psychological resources， also play a moderating and mediating role in individuals' coping with environmental changes. However， there is a lack of systematic research on how peer attachment affects the school adaptation of migrant children through psychological resilience and whether this process is moderated by sense of security. ObjectiveTo explore the relationship between peer attachment and school adaptation of migrant children and to examine the path of psychological resilience and sense of security in it， so as to provide references for improving the school adaptation of migrant children. MethodsUsing cluster sampling method， 695 migrant children in grades 4 to 6 of a primary school in an urban-rural fringe area of Sichuan Province were selected from April 1 to 30， 2022. Assessments were conducted using Revised Inventory for Parent and Peer Attachment （IPPA-R）， Resilience Scale for Chinese Adolescents （RSCA）， Scale of Sense of Security of Children Left Behind （SSSCLB） and Scale of School Adjustment of Student （SSAS）. Process 4.1 was used to examine the role of psychological resilience and sense of security. ResultsA total of 631 （90.79%） valid questionnaires were gathered. There were significant positive correlations among IPPA-R peer attachment subscale score， RSCA score， SSSCLB score and SSAS score （r=0.160~0.600， P<0.01）. Peer attachment had a significant positive predictive effect on the school adaptation （β=0.178， P<0.01） and psychological resilience （β=0.518， P<0.01） of migrant children. Psychological resilience had positive predictive effect on the school adaptation （β=0.467， P<0.01）. Psychological resilience played a partial mediating role in the relationship between peer attachment and school adaptation， with the mediating effect value was 0.242 （95% CI： 0.184~0.302）， accounting for 57.62% of the total effect. Moreover， the interaction term between psychological resilience and sense of security had a significant predictive effect on school adaptation （β=0.103， P<0.01）. ConclusionThe psychological resilience of migrant children plays a partial mediating role in the relationship between peer attachment and school adaptation， and the status of sense of security can moderate the relationship between psychological resilience and school adaptation of migrant children.

OBJECTIVE To explore the new idea of creating pharmaceutical science popularization oriented by internet medication consultation questions， and provide references for pharmacists to create high-quality pharmaceutical science popularization articles. METHODS By taking the internet medication consultation questions from September 1st， 2021 to February 28th， 2022 in a hospital as samples， pharmaceutical science popularization were created by using the Pareto chart for summarizing and analyzing the demands of the public pharmaceutical knowledge. The readers and creating cycle of pharmaceutical science popularization before and after the implementation of this method were compared by statistical analysis. RESULTS According to the Pareto principle， the types of consultation questions were mainly concentrated on usage and dosage， adverse reactions， and precautions； the types of drug consultation were mainly concentrated on respiratory system medications， anti-infective drugs， rheumatic immune system medications， and orthopedic medications， etc. Fifteen topics of science popularization were identified. Among them， 5 were published before 2022 and did not adopt the Pareto chart method， serving as the pre-method and consistent with the target theme group （A group）； 10 were published in 2022 after adopting the Pareto chart method， serving as the post- method group （B group）； 5 articles published before 2022 were selected randomly， without adopting the Pareto chart method and inconsistent with the target theme， serving as the pre-method and inconsistencies with the target theme group （C group）. Compared with the A group and the C group， the creating cycle of pharmaceutical science popularization in the B group was significantly reduced. Compared with the C group， the readers were significantly increased in the A group and the B group. CONCLUSIONS Pareto chart could help pharmacists utilize medication consultation questions to identify the pharmaceutical science popularization needed by the public， which could improve the efficiency and quality of creating pharmaceutical science popularization by pharmacists.

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).

Objective:To investigate the incidence and influencing factors of allergic reactions to cephalosporins.Methods:A cross-sectional study of 29 medical institutions in Zhejiang Province was conducted from April 2021 to June 2021.The incidence of allergic reactions to cephalosporins was investigated,and the influencing factors of cephalosporin-induced allergic reactions were analyzed by Poisson regression.Results:A total of 56 155 patients were included in this study.The total incidence of allergic reactions to cephalosporin was 1.67‰,the highest incidence of anaphylaxis occurred for ceftizoxime(4.27‰),followed by ceftriaxone(3.49‰)and cefotaxime(2.40‰).There was no significant difference in the incidence of allergic reactions between patients with negative skin tests and those without skin tests(1.75％o vs.1.63‰,RR=1.07,95％CI:0.70-1.63,P＞0.05).Poisson regression showed that body mass index(BMI)＜18.5 kg/m2(RR=2.43,95％CI:1.23-4.82,P＜0.05)and history of β-lactam antibiotics allergy(RR=33.88,95％CI:1.47-781.12,P＜0.05)increased cephalosporin-induced anaphylaxis.Compared with cefuroxime,the risk of allergic reactions was increased for ceftriaxone(RR=3.08,95％CI:1.70-5.59,P＜0.01),ceftazidime(RR=1.89,95％CI:1.03-3.47,P＜0.05),and ceftizoxime(RR=3.74,95％CI:1.64-8.50,P＜0.01).Conclusions:Lower BMI and history of β-lactam antibiotics allergy increase the risk of cephalosporin allergic reactions.The routine skin test may not reduce the occurrence of allergic reactions to cephalosporins. This study has been registered at Chinese Clinical Trial Registry(ChiCTR2200064314).

Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

Objective:To explore the effect of timely induction intervention on postpartum urination in primipara during vaginal delivery, so as to provide the evidence for preventing the occurrence of postpartum urinary retention and relieving the pain of primipara.Methods:This study adopted a randomized controlled trial design, and selected 400 cases of primipara who were hospitalized for vaginal delivery in the Obstetric Department of Dalian Women and Children's Medical Group Sports New Town Hospital from June 2021 to September 2022 as the study objects by convenience sampling method. They were divided into the intervention group and the control group with 200 cases each by random number table method, and the control group received routine postpartum care. Instruct active urination within 6 hours after delivery. The intervention received timely induction urination intervention. The general condition and bladder urine volume of the women in the intervention group were evaluated at 2, 4, 6 h after delivery, respectively, and personalized guidance was implemented, including the frequency of massage of the bottom of the uterus, the control of water intake, the selection of methods and timing of inducing urination, etc., and routine postpartum care was given when the women completed their first urination and had no complaints of discomfort. The first urination time, first urination volume, first bladder irritation during the first urination and the incidence of postpartum urinary retention in different periods were compared between the two groups.Results:The patients in the control group were (29.60 ± 3.20) years old, while the patients in the intervention group were (28.81 ± 3.42) years old. The first urination time in the intervention group was (6.89 ± 2.18) h, which was shorter than that in the control group (9.11 ± 3.86) h, and the difference was statistically significant ( t=-2.49, P<0.01). The first urination volume in the intervention group was (322.36 ± 120.15) ml, which was higher than that in the control group (262.93 ± 105.68) ml, and the difference was statistically significant ( t=3.39, P<0.05). The incidence of the first bladder irritation in the intervention group was 22.0%(44/200), which was lower than that in the control group 33.5%(67/200), and the difference was statistically significant ( χ2=6.60, P<0.05). The incidence of postpartum urinary retention within 24 h in the intervention group was 5.5%(11/200), which was lower than that in the control group 11.5%(23/200), and the difference was statistically significant ( χ2=4.63, P<0.05). The incidence of postpartum urinary retention within 1 week in the intervention group was 9.5%(19/200), which was lower than that in the control group 16.5%(33/200), and the difference was statistically significant ( χ2=4.33, P<0.05). There was no significant difference in the incidence of postpartum urinary retention within 24 to 72 h between the two groups ( P>0.05). Conclusions:Timely induction intervention can reduce the incidence of postpartum urinary retention, shorten the time of first urination, increase the volume of first urination and improve the comfort of first urination, which is worthy of clinical application.

Objective:To explore the current situation of fear of progression among parents of school-age children with asthma, and to analyze the latent profile categories and influencing factors, so as to provide the reference for the formulation of prevention and intervention.Methods:Using convenient sampling method, school-age children with asthma and their parents treated in the Affiliated Children's Hospital of Xiangya School of Medicine, Central South University from March to August 2023 were selected as the study objects. The General Data Questionnaire, Parent Fear of Progression Scale, Childhood Asthma Control Test, and Social Support Rating Scale were used to investigate school-age children with asthma and their parents. Latent profile analysis was performed on the fear of disease progression among parents of school-age children with asthma, and χ2 test and binary Logistic regression were used to explore the influencing factors. Results:A total of 210 parents of the children were included with 51 fathers and 159 mothers.The age distribution was 20-30 years old with 42 parents, 31-40 years old with 112 parents, 41-50 years old with 56 parents. In 210 children with asthma, there were 123 males and 87 females, with 141 cases aged<10 years old and 69 cases aged ≥10 years old. The fear of progression among parents of school-age children with asthma could be divided into two potential profile categories: "psychological dysfunction group (46.7%, 98/210)" and "psychological health good group (53.3%, 112/210)". The results of binary Logistic regression analysis showed that asthma family history, combined allergic rhinitis, child-parent relationship, marital status, asthma symptom control level, and social support level were the influencing factors of fear of progression among parents of school-age children with asthma( OR values were 0.925-10.010, all P<0.05). Conclusions:The fear of progression among parents of school-age children with asthma is at a moderate level, and there are obvious different classification characteristics. In the future, targeted and precise prevention and intervention should be implemented according to the category characteristics of fear of progression among parents of school-age children with asthma.
