Introduction: Poor feeding practices can result in malnutrition, which may have long-term negative effects on children’s physical and cognitive development. There is limited qualitative research exploring feeding practices among caregivers of urban poor, even though their children are highly vulnerable to undernutrition. Aim: This qualitative study aimed to explore and compare the feeding practices, barriers and coping strategies of caregivers of well-nourished and undernourished children aged three to five years living in public low-cost housing in Kuala Lumpur, Malaysia. Methods: Semi-structured in-depth interviews were conducted among 27 caregivers. Caregivers were purposively selected using purposive sampling and categorized into two groups based on their children’s growth status: families with well-nourished children (FWWC; n=15) and families with undernourished children (FWUC; n=12). Thematic analysis was conducted. Results: Two main themes emerged: feeding practices and barriers and coping strategies to feed children. FWWC caregivers demonstrated certain unique yet beneficial practices. They emphasized responsive feeding techniques, such as using nutritious snacks, promising outdoor activities, and involving children in meal preparation at home as effective strategies to increase children’s food intake. Contrarily, FWUC caregivers practiced less responsive feeding techniques, such as forcing, ignorance, and distraction. Caregivers from both groups experienced similar barriers (child barriers and family barriers) and applied comparable coping strategies (ignorance, distraction, pressure and force, compromise, and creativity). Conclusion: Understanding feeding practices of caregivers of healthy and undernourished children can guide the development of culturally tailored interventions and policies. These efforts can help address barriers and improve child nutrition through responsive feeding, ultimately preventing undernutrition.

The goal of medical talent training under the new medical science concept is to comprehensively enhance the quality of medical education and cultivate high-quality medical talents with interdisciplinary integration, innovation spirit, and an international perspective to meet the demands of the new era.

Objective:To explore the establishment, implementation, and application effect of the annual progressive assessment mode for standardized training of resident physicians in a medical laboratory base.Methods:Since 2020, the base has improved the annual progressive assessment system through assessment system establishment, question bank construction, routine assessment, rotation examination, and annual examination. This new assessment mode was adopted for the residency trainees enrolled in the base after 2020. The control group consisted of seven residency trainees enrolled before 2020, while the experimental group comprised 13 trainees enrolled in 2020 and later. The two groups were compared based on the rotation and annual examination scores of second- and third-year trainees, as well as their academic achievements. Additionally, teaching outcomes of the base before and after 2020 were analyzed. The t test, rank-sum test, and Fisher's exact test were performed using SPSS 27.00. Results:There were no significant differences in age, sex, and education level between the two groups. The experimental group showed significantly higher scores than the control group in theory assessment ( P<0.001 for second-year trainees and P=0.008 for third-year trainees) and skill assessment ( P<0.001 for second-year trainees and P=0.038 for third-year trainees) in rotation examination, as well as in theory assessment (both P<0.001) and skill assessment (both P<0.001) in annual examination. The improvement was particularly pronounced among second-year trainees. The trainees of the experimental group submitted 17 case reports in three years, and won awards at national conferences, provincial conferences, and institutional case speech competitions. In a national academic conference, the trainees won the second prize of "Excellent Case". Since 2020, we have been granted with our first teaching reform project and published our first teaching article. To date, we have obtained five teaching reform projects, published six teaching articles, and won multiple awards in provincial and institutional teaching competitions. Conclusions:The establishment of the annual progressive assessment mode is critical for training high-quality laboratory physicians, and puts forward higher requirements for residency training teachers.

Objective:To investigate the effect of mindfulness-based cognitive therapy on the sense of personal control and illness perception of young and middle-aged patients after percutaneous coronary intervention (PCI), so as to provide theoretical and practical guidance for the psychological care of patients after PCI.Methods:A randomized controlled trial was conducted. From January 2022 to December 2023, young and middle-aged patients after PCI admitted to the Department of Cardiology, Qinhuai Medical District, Eastern Theater Command General Hospital of the Chinese People′s Liberation Army were selected as the research subjects by convenient sampling method, patients were divided into the experimental group and the control group by the random number table method. The control group was given routine nursing, and the experimental group was given mindfulness-based cognitive therapy on the basis of routine nursing. The Personal Mastery Scale (PMS), Cardiac Self-Efficacy Questionnaire (CSEQ), and Brief Illness Perception Questionnaire (BIPQ) were used to evaluate personal sense of control, self-efficacy, and illness perception before and after the intervention respectively.Results:A total of 80 young and middle-aged patients after PCI were included. There were 40 cases in the control group, including 25 males and 15 females, aged (49.43 ± 5.55) years old. There were 40 cases in the experimental group, including 19 males and 21 females, aged (49.03 ± 4.19) years old. Before the intervention, there was no statistically significant difference in the PMS, CSEQ and BIPQ scores between the two groups of patients (all P>0.05). After the intervention, the PMS, CSEQ scores of the patients in the experimental group were (23.03 ± 2.54), (45.85 ± 8.16) points respectively, which were higher than (21.95 ± 2.28), (39.05 ± 8.78) points in the control group, the BIPQ score of the patients in the experimental group was(39.63 ± 8.12) points, which was lower the (45.45 ± 8.64) points in the control group, the differences were statistically significant ( t=-2.00, -3.59, 3.11, all P<0.05).

Sennoside A(SA),a typical prodrug,exerts its laxative effect only after its transformation into rhei-nanthrone catalyzed by gut microbial hydrolases and reductases.Hydrolases have been identified,but reductases remain unknown.By linking a photoreactive group to the SA scaffold,we synthesized a photoaffinity probe to covalently label SA reductases and identified SA reductases using activity-based protein profiling(ABPP).From lysates of an active strain,Bifidobacterium pseudocatenulatum(B.pseu-docatenulatum),397 proteins were enriched and subsequently identified using mass spectrometry(MS).Among these proteins,chromate reductase/nicotinamide adenine dinucleotide(NADH)phosphate(NADPH)-dependent flavin mononucleotide(FMN)reductase/oxygen-insensitive NADPH nitroreductase(nfrA)was identified as a potent SA reductase through further bioinformatic analysis and The Universal Protein Resource(UniProt)database screening.We also determined that recombinant nfrA could reduce SA.Our study contributes to further illuminating mechanisms of SA transformation to rheinanthrone and simultaneously offers an effective method to identify gut bacterial reductases.
