RESUMO

As a widely-known neuropsychiatric disorder, the exact pathogenesis of depression remains elusive. MiRNA-206 (miR-206) is conventionally known as one of the myomiRs and has two forms: miR-206-3p and miR-206-5p. Recently, miR-206 has been demonstrated to regulate the biosynthesis of brain-derived neurotrophic factor (BDNF), a very popular target involved in depression and antidepressant responses. Here we assumed that miR-206 may play a role in depression, and various methods including the chronic social defeat stress (CSDS) model of depression, quantitative real-time reverse transcription PCR, western blotting, immuofluorescence and virus-mediated gene transfer were used together. It was found that CSDS robustly increased the level of miR-206-3p but not miR-206-5p in the hippocampus. Both genetic overexpression of hippocampal miR-206-3p and intranasal administration of AgomiR-206-3p induced not only notable depressive-like behaviors but also significantly decreased hippocampal BDNF signaling cascade and neurogenesis in naïve C57BL/6J mice. In contrast, both genetic knockdown of hippocampal miR-206-3p and intranasal administration of AntagomiR-206-3p produced significant antidepressant-like effects in the CSDS model of depression. Furthermore, it was found that the antidepressant-like effects induced by miR-206-3p inhibition require the hippocampal BDNF-TrkB system. Taken together, hippocampal miR-206-3p participates in the pathogenesis of depression by regulating BDNF biosynthesis and is a feasible antidepressant target.

RESUMO

BACKGROUND: Reference sequences play a vital role in next-generation sequencing (NGS), impacting mapping quality during genome analyses. However, reference genomes usually do not represent the full range of genetic diversity of a species as a result of geographical divergence and independent demographic events of different populations. For the mitochondrial genome (mitogenome), which occurs in high copy numbers in cells and is strictly maternally inherited, an optimal reference sequence has the potential to make mitogenome alignment both more accurate and more efficient. In this study, we used three different types of reference sequences for mitogenome mapping, i.e., the commonly used reference sequence (CU-ref), the breed-specific reference sequence (BS-ref) and the sample-specific reference sequence (SS-ref), respectively, and compared the accuracy of mitogenome alignment and SNP calling among them, for the purpose of proposing the optimal reference sequence for mitochondrial DNA (mtDNA) analyses of specific populations RESULTS: Four pigs, representing three different breeds, were high-throughput sequenced, subsequently mapping reads to the reference sequences mentioned above, resulting in a largest mapping ratio and a deepest coverage without increased running time when aligning reads to a BS-ref. Next, single nucleotide polymorphism (SNP) calling was carried out by 18 detection strategies with the three tools SAMtools, VarScan and GATK with different parameters, using the bam results mapping to BS-ref. The results showed that all eighteen strategies achieved the same high specificity and sensitivity, which suggested a high accuracy of mitogenome alignment by the BS-ref because of a low requirement for SNP calling tools and parameter choices. CONCLUSIONS: This study showed that different reference sequences representing different genetic relationships to sample reads influenced mitogenome alignment, with the breed-specific reference sequences being optimal for mitogenome analyses, which provides a refined processing perspective for NGS data.

RESUMO

OBJECTIVE: To evaluate the relationship between religious beliefs and mental state, care burden, and quality of life in parents of infantile patients with CHD. METHODS: A cross-sectional study was conducted at a provincial hospital in Fujian, China. In this study, 114 parents of infant patients with CHD were successfully enrolled. Data were collected using the Duke University Religion Index, Hospital Anxiety and Depression Scale, Zarit Caregiver Burden Interview, and 36-Item Short-Form Health Survey. RESULTS: The organisational religious activity, non-organisational religious activity, and intrinsic religiosity of parents were significantly related to the care burden and quality of life, and the two dimensions of non-organisational religious activity and intrinsic religiosity of parents were significantly related to their anxiety symptoms. No association was found between parents' religious beliefs and their depressive symptoms. Among Buddhist parents, non-organisational religious activity and intrinsic religiosity reduced the care burden and improved quality of life. Among Christian parents, organisational religious activity and non-organisational religious activity were found to reduce the care burden, while organisational religious activity and intrinsic religiosity were found to improve quality of life. There was no correlation between the sub-dimensions of religious beliefs and a negative impact on the care process in Muslim parents. CONCLUSION: Religious beliefs have a protective effect on the parents of infant patients with CHD. They help relieve parents' anxiety, reduce their care burden, and improve their quality of life. In addition, different religious beliefs have different dimensions of influence on caregivers.

RESUMO

The complete mitochondrial genome (mitogenome) of Aglossa dimidiata (Lepidoptera: Pyralidae) was sequenced using high-throughput sequencing. The mitogenome of A. dimidiata was 15,225 bp in length. It comprised 37 typical genes and one control region. All protein-coding genes (PCGs) were initiated with ATN, except for COX1 (TTG). All PCGs used TAN as stop codon, except for ND5 and ND4 terminated with incomplete T. Twenty-two tRNA genes ranged from 61 to 71 bp in size. The monophyly of family Pyralidae and the sister relationship between A. dimidiata and Orthopygia glanucinalis are both supported by maximum likelihood method using the nucleotide sequences of 13 PCGs.

RESUMO

OBJECTIVE: The primary objective of this study was to assess the effect of selective lobar blockade on the risk of hypoxemia during one-lung ventilation in pediatric patients undergoing thoracoscopic surgery. DESIGN: This was a retrospective matched case-control cohort study. SETTING: The study was performed in a teaching hospital. PARTICIPANTS: A total of 60 pediatric patients who underwent thoracoscopic surgery in the authors' hospital from March 2020 to March 2021 were analyzed. INTERVENTIONS: The authors examined their electronic medical records and found 30 patients in whom selective lobar blockade was used. These patients then were matched to 30 other patients in whom routine main bronchial blockade was performed in the authors' center based on age, weight, sex, side of surgery, and type of surgery. MEASUREMENTS AND MAIN RESULTS: The inclusion criteria were four-fold: (1) pediatric patients with scheduled thoracoscopic resection of the middle and lower lobe lesions; (2) no obvious anesthesia or surgical contraindications; (3) American Society of Anesthesiologists class I to II; and (4) age younger than one year old. The exclusion criteria were as follows: (1) pediatric patients whose trachea was intubated with a size less than 3.0 mm; (2) a difficult airway; (3) changes in ventilation patterns during surgery; and (4) severe pneumonia and respiratory and circulatory system dysfunction. The following patient data were collected: (1) general clinical information; (2) mean arterial blood pressure, heart rate, central venous pressure, airway peak pressure (Ppeak), oxygenation index (PaO2/FIO2 ratio), and alveolar-arterial oxygen differential pressure (AaDO2) at different time points; that is, before one-lung ventilation (OLV) (T1), ten minutes after OLV (T2), and ten minutes after the end of OLV (T3); (3) degree of lung collapse ten minutes after OLV; (4) operative duration; and (5) the prevalence of hypoxemia, the number of adjustments required for intraoperative displacement of the bronchial blocker, and pulmonary atelectasis. A total of 135 patients were selected, and 60 pediatric patients (30 in group S and 30 in group R) were included in this study. There were no significant differences in age, sex, weight, general preoperative data, degree of lung collapse, or operative duration (p > 0.05). The perioperative hemodynamics between the two groups were not statistically significant (p > 0.05). The oxygenation index, AaDO2, and Ppeak were not significantly different between the two groups at the T1 time point (p > 0.05). However, the oxygenation index was higher, and AaDO2 and Ppeak were lower in group S than in group R at the T2 and T3 time points (p < 0.05). The incidence of atelectasis, the prevalence of hypoxemia, and the number of adjustments required for intraoperative displacement of the bronchial blocker in group S were lower than those in group R (p < 0.05). CONCLUSION: Selective lobar bronchial blockade, using a bronchial blocker in pediatric thoracoscopic surgery, may represent an alternative to excluding the main bronchial blockade for patients undergoing middle and lower lobe procedures, which may improve intraoperative oxygenation and reduce postoperative atelectasis.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the effect of using telemedicine to improve the quality of life of parents of infants with congenital heart disease (CHD) surgery after discharge. METHODS: A prospective randomized controlled study was conducted in a provincial hospital in China from November 2020 to April 2021 to compare the quality of life of parents of infants with CHD surgery after discharge between the WeChat follow-up group and the outpatient follow-up group. A total of 84 patients (42 in each group) and 168 parents (84 in each group) participated in this study. RESULTS: One month after discharge, the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores of parents in the intervention group were significantly lower than those in the control group (P < 0.05). Compared with the SAS and SDS scores at discharge, the scores of parents in the intervention group were significantly lower at 1 month after discharge (P < 0.05), while the scores of parents in the control group were similar at 1 month after discharge (P > 0.05). At discharge, in both the intervention group and the control group, the SAS and SDS scores of the mothers were higher than those of the fathers (P < 0.05). One month after discharge, in the control group, the SAS and SDS scores of the mothers were higher than those of the fathers (P < 0.05). One month after discharge, in the intervention group, the SAS and SDS scores of the mothers were similar to those of the fathers (P > 0.05). The comparison of the SAS and SDS scores of parents with different education levels showed that in both the intervention group and control group, the lower the parents' educational levels, the higher their SAS and SDS scores (P < 0.05). One month after discharge, in the control group, the lower the parents' education levels, the higher their SAS and SDS scores (P < 0.05). One month after discharge, in the intervention group, the SAS and SDS scores were similar among parents with different educational levels. The results of the World Health Organization Quality of Life Brief scale showed that the scores of the physiological, psychological, social and environmental fields at 1 month after discharge in the intervention group were significantly higher than those in the control group (P < 0.05). CONCLUSION: Providing health education and medical support to the parents of infants with CHD surgery after discharge via telemedicine can effectively relieve parents' anxiety and depression and improve their quality of life.

RESUMO

BACKGROUND: To compare the short-term safety and efficacy of right anterolateral minithoracotomy (ALMT) and median sternotomy (MS) for the surgical treatment of atrial septal defects (ASDs). METHODS: The PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched for comparative studies focusing on surgical repair of ASDs via ALMT or MS published up to the end of April 27, 2020. We used random-effect or fixed-effect models to obtain pooled estimates. RESULTS: A total of 7 publications, including 665 patients (ALMT 296 and MS 369), were included. Age (WMD: 1.80 years, 95% CI 0.31-3.29), weight (WMD: - 0.91 kg, 95% CI - 5.57 to 3.75), sex distribution (OR: 1.00, 95% CI 0.74-1.35) and surgical type (patch or direct closure) (OR: 1.00, 95% CI 0.67-1.49) were comparable in the ALMT group and MS group. No significant differences in the success rate (OR 0.23; 95% CI 0.05-1.07) or severe complication rate (OR 1.46; 95% CI 0.41-5.22) were found between the ALMT group and the MS group. In addition, the differences in the cardiopulmonary bypass (CPB) time (WMD 6.33; 95% CI - 1.92 to 14.58 min, p = 0.13) and the operation time (WMD 5.23; 95% CI - 12.49 to 22.96 min, p = 0.56) between the ALMT group and the MS group were not statistically significant. However, the ALMT group had a significantly longer aortic cross-clamp time (2.37 min more, 95% CI 1.07-3.67 min, p = 0.0003). The intubation time was 1.82 h shorter (95% CI - 3.10 to - 0.55 h; p = 0.005), the intensive care unit (ICU) stay was 0.24 days shorter (95% CI - 0.44 to - 0.04 days; p = 0.02), and the postoperative hospital stay was 2.45 days shorter (95% CI - 3.01 to - 1.88 days; p < 0.00001) in the ALMT group than in the MS group. Furthermore, the incision length was significantly shortened by 8.97 cm in the ALMT group compared with the MS group (95% CI - 9.36 to - 8.58 cm; p < 0.00001). CONCLUSIONS: In the surgical treatment of ASD, ALMT and MS are equally safe and effective in terms of success rates and severe complication rates. The surgical procedures are equally difficult, but ALMT is associated with a faster functional recovery and better cosmetic results. Compared to MS, ALMT is the better choice for select ASD patients.

RESUMO

OBJECTIVE: This study aimed to explore the effect of WeChat follow-up management on improving the parents' mental status and the quality of life of premature newborns with patent ductus arteriosus (PDA) after discharge. METHODS: Participants were randomly divided into an intervention group and a control group. WeChat was used in the intervention group for the postdischarge follow-up management, while the control group was managed traditionally. The psychological status and quality of life of the parents of the two groups were analyzed and compared. RESULTS: The SAS and SDS scores in the intervention group at three months after discharge were significantly better than those at discharge, but there was no significant change in the control group. During the three-month follow-up, the SAS and SDS scores in the intervention group were significantly better than those in the control group. The WHOQOL-BREF scale scores in the intervention group were significantly better than those in the control group in physiology, psychology, social relations, and the environment. The total quality of life score in the intervention group was also significantly better than that in the control group. All patients in the intervention group were followed up as appropriate, while five patients in the control group were lost to follow-up. The incidence of pneumonia and feeding intolerance in the intervention group were significantly lower than those in the control group. CONCLUSION: The application of WeChat in the follow-up management of premature infants with PDA could alleviate parents' anxiety and depression in taking care of their children at home and can improve their quality of life.

RESUMO

OBJECTIVE: The objective of the present study is to explore the effect of different feeding intervals on the feeding outcomes of infants who underwent ventricular septal defect (VSD) closure. METHODS: This study is a prospective, randomized controlled trial conducted by a provincial hospital in China. According to different feeding intervals, 78 eligible participants were randomly divided into Group A (2-h interval, n = 39) and Group B (3-h interval, n = 39). The basic clinical data, total feeding time, incidence of feeding intolerance, and nurse job satisfaction scores of the two groups were collected. RESULTS: The total feeding time in Group A was significantly longer than that in Group B (142.5 ± 15.4 vs. 132.0 ± 16.1 min/d, p = .020). The nurse job satisfaction scores in Group A were significantly lower than those in Group B (101.7 ± 9.8 vs. 108.8 ± 10.1, p = .005). There were no significant differences in the duration of mechanical ventilation (3.7 ± 1.1 vs. 3.9 ± 1.0 d, p = .272), length of ICU stay (4.5 ± 1.1 d vs. 4.7 ± 0.9 d, p = .451), or length of hospital stay (13.2 ± 1.4 vs. 13.3 ± 1.0 d, p = .642) between the two groups. Although the incidence of feeding intolerance in Group A was slightly lower than that in Group B, the difference was not statistically significant. CONCLUSION: Feeding at an interval of 2 or 3 h has no significant effect on the feeding outcomes of infants, and feeding at intervals of 3 h can reduce nurses' workload and improve nursing job satisfaction.

RESUMO

Background: This study aimed to evaluate the effects of pulmonary surfactant (PS) combined with high-frequency oscillatory ventilation (HFOV) or conventional mechanical ventilation (CMV) in infants with acute respiratory distress syndrome (ARDS) after congenital cardiac surgery. Methods: A total of 61 infants with ARDS were eligible and were randomised to the CMV + PS group (n = 30) or the HFOV + PS group (n = 31) between January 2020 and December 2020. The primary outcomes were the changes in arterial blood gas parameters. The duration of mechanical ventilation, length of hospitalisation and the incidence of complications were considered secondary outcomes. Results: A total of 61 infants completed the study. In the HFOV + PS group, the blood gas analysis results were significantly improved (P < 0.05), while the duration of mechanical ventilation and length of hospitalisation were shorter than the CMV + PS group (P < 0.05). However, the incidence of complications was not different between the two groups (P > 0.05). Conclusions: Compared with the CMV + PS group, the HFOV + PS group showed significantly improved ABG variables and had a shortened length of hospitalisation and mechanical ventilation in infants with ARDS after cardiac surgery.

RESUMO

OBJECTIVES: This study aimed to explore the effect of applying WeChat in the follow-up and health education of children after congenital heart disease (CHD) surgery during the coronavirus disease 2019 (COVID-19) epidemic. METHODS: Data from 135 children were retrospectively analyzed. The care burden, anxiety, depression, and satisfaction of the parents of patients at home were analyzed and compared. RESULTS: One month after discharge, the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Zarit Burden Interview (ZBI), and Patient Satisfaction Questionnaire-18 scores of the WeChat follow-up group were significantly better than those of the outpatient follow-up group (p < 0.05). Compared with the discharge time, the SAS, SDS, and ZBI scores were significantly improved in the WeChat follow-up group but not in the outpatient follow-up group (p < 0.05). CONCLUSION: During the COVID-19 epidemic, the application of WeChat to the follow-up management of children after CHD surgery can effectively reduce care burden and relieve anxiety and depression in parents at home. It can also improve the satisfaction of parents with medical treatment.

RESUMO

OBJECTIVE: To investigate the effect of WeChat follow-up management of infants who underwent ventricular septal defect (VSD) repair on parents' disease knowledge and quality of life. METHODS: Participants were randomly assigned to an intervention group (n = 40) or a control group (n = 40). The intervention group was followed up with WeChat, while the control group was followed up using a traditional method. The disease knowledge, mental state, and quality of life of the two groups of parents were analyzed and compared. RESULTS: During the 3-month follow-up period, the PedSQL (PedsQL family impact module) results showed that the overall score in the intervention group was significantly higher than that in the control group. The parents in the intervention group were better at managing "emotion control," "worry," and "family communication" than those in the control group. The results of the LKQCHD (Leuven congenital heart disease knowledge questionnaire) showed that the parents in the intervention group had a higher mastery of "basic knowledge and treatment of congenital heart disease," "related complications," and "postoperative rehabilitation" than those in the control group. CONCLUSION: Knowledge education and psychological counseling for parents of children who underwent VSD repair through WeChat follow-up management can effectively improve parents' knowledge, relieve their anxiety and sadness, and improve their quality of life.

RESUMO

BACKGROUND: To explore the feasibility and superiority of applying the WeChat platform in a midterm follow-up of surgical repair for ventricular septal defects in infants. METHODS: Eighty-six infants with VSD who underwent surgical repair were divided into an outpatient follow-up group and a WeChat follow-up group. The clinical data, including complications, economic cost, time spent, loss to follow-up rate, and parents' satisfaction at the 3-month and 1-year follow-ups, were recorded and analysed. RESULTS: There was no significant difference in the incidence of post-operative complications between the two groups. Although the loss to follow-up rate in the WFU group was lower than that of the OFU group, the difference was not statistically significant. The economic cost and time spent in the 3 months and 1 year after discharge in the WFU group were significantly lower than those in the OFU group. One year after discharge, the PSQ-18 score of the WFU group was significantly higher than that of the OFU group. CONCLUSION: Compared with outpatient follow-up, the WeChat platform at the midterm follow-up after surgical repair of VSDs in infants has the advantages of saving time and economic costs and improves parents' satisfaction.

RESUMO

Deep hypothermic circulatory arrest (DHCA) during heart surgery may induce neuroinflammation leading to neurocognitive dysfunction. Chlorogenic acid (CA) is a common phytochemical, which can attenuate neuroinflammation. Nevertheless, the underlying mechanism involved in the anti-inflammatory effect of CA after DHCA is unknown. The present study therefore characterized the anti-inflammatory functions of CA after DHCA using in vivo and in vitro DHCA models. The activation of microglia, inflammatory cytokine levels, and the NF-κB pathway were measured. The results showed that CA treatment ameliorated neurocognitive function and reduced the inflammatory cytokine levels in the brain and circulation. Furthermore, the microglial and NF-κB activations were suppressed after DHCA. CA exerted the same anti-inflammatory effect in hypothermia OGD microglial cells as the in vivo study. Additional studies indicated that the regulation of ubiquitin ligase activity of TRAF6 and RIP1 by CYLD was related to the mechanism involving inhibition of CA in the NF-κB pathway. Together, the results showed that CA may attenuate neuroinflammation after DHCA by modulating the signaling of CYLD/NF-κB.

RESUMO

SARS-CoV-2 infection causes a wide spectrum of clinical manifestations in humans, and olfactory dysfunction is one of the most predictive and common symptoms in COVID-19 patients. However, the underlying mechanism by which SARS-CoV-2 infection leads to olfactory disorders remains elusive. Herein, we demonstrate that intranasal inoculation with SARS-CoV-2 induces robust viral replication in the olfactory epithelium (OE), not the olfactory bulb (OB), resulting in transient olfactory dysfunction in humanized ACE2 (hACE2) mice. The sustentacular cells and Bowman's gland cells in the OE were identified as the major target cells of SARS-CoV-2 before invasion into olfactory sensory neurons (OSNs). Remarkably, SARS-CoV-2 infection triggers massive cell death and immune cell infiltration and directly impairs the uniformity of the OE structure. Combined transcriptomic and quantitative proteomic analyses revealed the induction of antiviral and inflammatory responses, as well as the downregulation of olfactory receptor (OR) genes in the OE from the infected animals. Overall, our mouse model recapitulates olfactory dysfunction in COVID-19 patients and provides critical clues for understanding the physiological basis for extrapulmonary manifestations of COVID-19.

RESUMO

Pyemotes spp. are small, toxic, ectoparasitic mites that suppress Coleoptera, Hemiptera, and Lepidoptera plant pests. To explore their potential use as a biocontrol agent, we studied the reproductive development, paralytic process, time to lethality and mortality, and searching ability of Pyemotes zhonghuajia on different developmental stages of the oriental leafworm moth, Spodoptera litura. Pyemotes zhonghuajia gained 14,826 times its body weight during pregnancy. One single P. zhonghuajia female could rapidly kill one S. litura egg and first to third instar larvae, but not fourth to sixth instar larvae, prepupae, or pupae within 720 min. Pyemotes zhonghuajia could develop on eggs, first to sixth larvae, and pupae, but only produced offspring on the eggs and pupae. A single P. zhonghuajia female (an average weight of 23.81 ng) could paralyze and kill one S. litura third instar larvae (an average weight of 16.29 mg)-680,000 times its own weight. Mites significantly affected the hatch rate of S. litura eggs, which reduced with increasing mite densities on S. litura eggs. Releasing 50 or 100 P. zhonghuajia in a 2 cm searching range resulted in significantly higher mortality rates of S. litura first instar larvae within 48 h compared to second and third instar larvae in searching ranges of 4.5 and 7.5 cm within 24 h. To the best of our knowledge, this is the first study to reveal that P. zhonghuajia undergoes the greatest changes in weight during pregnancy of any adult female animal and has the highest lethal weight ratio of any biocontrol agent.

RESUMO

In this study, we sequenced and annotated the complete mitochondrial genome (mitogenome) of Neotoxoptera formosana (Takahashi) (Hemiptera: Aphididae). The complete mitogenome of N. formosana is 15,642 bp in length, and includes 13 protein-coding genes (PCGs), 2 ribosome RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and one control region. The overall base composition was as follows: 45.2% of A, 5.8% of G, 10.5% of C, and 38.4% of T, with a total of A + T content of 83.6%. The phylogenetic tree showed that N. formosana and Myzus persicae were clustered into one branch. This result will enrich the mitogenome of family Aphididae.

RESUMO

Primary brainstem haemorrhage (PBH) is characterized by acute onset, rapid deterioration, many complications, and poor prognosis. Its treatment has been controversial. This study aimed to explore the clinical risk factors of postoperative survival and neurological function recovery of stereotactic aspiration in the treatment of PBH. The clinical data of 65 patients with severe brainstem haemorrhage from February 2019 to February 2020 in the First Hospital of Hebei Medical University were reviewed. All patients were treated with stereotactic haematoma aspiration. We determined the survival status of patients at 30 days after the operation and the recovery of neurological function at 90 days. The modified Rankin Scale score (mRS) was used to assess the survival status. The 30-day mortality rate was 23.1% (15 patients). The proportion of patients with good neurological recovery at 90 days after the operation was 32.3% (21 patients). According to the multivariate logistic regression analysis, the haematoma classification was an independent risk factor for postoperative survival (OR = 0.197, 95% CI: 0.016-0.385, p = 0.046) and recovery of neurological function 90 days after surgery (OR = 0.019, 95% CI: 0.001-0.267, p = 0.003). The haematoma classification is an independent risk factor for 30-day mortality and recovery of neurological function 90 days after surgery. Massive and basal-tegmental haematomas were associated with higher mortality. The prognosis of patients with unilateral and bilateral tegmental haematoma was better than that of patients with other haematoma types.

RESUMO

AIM: This study aimed to investigate the impact of WeChat follow-up education on infants' breastfeeding efficiency after congenital cardiac surgery and parents' satisfaction. METHODS: A prospective study was conducted in a provincial hospital in China. Sixty participants were divided into two groups: 30 participants in the study group received WeChat follow-up health education, and 30 participants in the control group received postoperative routine nursing education for infants after congenital cardiac surgery. The infants' breastfeeding efficiency, parents' satisfaction and relevant clinical data were recorded and analysed. RESULTS: After the WeChat follow-up intervention, the breastfeeding efficacy score, the parents' satisfaction score and the exclusive breastfeeding rate in the study group were significantly higher than those in the control group (P < 0.05). There was no significant difference in the incidence of feeding intolerance, abdominal distension, dyspeptic diarrhoea, weight gain or recurrent vomiting between the two groups during the 3-month follow-up period. CONCLUSION: WeChat education can improve infants' breastfeeding efficiency after congenital cardiac surgery and can improve parents' satisfaction and exclusive breastfeeding rate during the short-term follow-up period.
