ABSTRACT
Objective:To investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group (79 patients) undergoing fistulectomy without granulation treatment, and a control group (61 patients) where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale(SBSES). Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

【Objective】 To explore the predictive value of combined thromboelastography(TEG), coagulation index and platelet parameters in evaluating the risk of thrombosis in patients with chronic venous insufficiency(CVI). 【Methods】 A total of 359 patients with CVI were enrolled in our hospital from November 2020 to March 2022, and divided into VTE group and non-VTE group according to the occurrence of venous thromboembolism (VTE).The baseline characteristics of the two groups and the value of combined TEG, coagulation index and platelet parameters in predicting the risk of VTE in patients with CVI were analyzed. The risk factors were screened by univariate logistic regression analysis, and the prediction model was constructed by multivariate logistic regression. The performance of the model was evaluated by area under the curve (AUC) and sensitivity specificity. 【Results】 Compared with the non-VTE group, the R value (3.27±0.71 vs 3.87±1.16, P<0.05), the prothrombin time (PT)(11.08±3.02 vs 12.86±3.48, P<0.001)and the platelet distribution width (PDW) (12.01±3.87 vs 13.98±3.20, P<0.001)of the VTE group decreased, while fibrinogen (Fib) (3.46 vs 3.10, P<0.05) and D-dimer (DD) (3.00 vs 1.12, P<0.001)increased. It was found that the area under the ROC curve of the thrombosis prediction model based on PT, DD, R value, Fib and PDW was 0.842 8, with the sensitivity and specificity of 36.78% and 95.59%, respectively. The decision curve analysis(DCA)indicated that patients would benefit when the model′s predicted probability ranged from 0.1 to 0.7. 【Conclusion】 The combination of TEG, coagulation index and platelet parameters is effective in predicting the risk of VTE in patients with CVI.
ABSTRACT
@#Objective: To explore the balance of peripheral blood T helper 17 cells/regulatory T cell (Th17/Treg) ratio and the polarization ratio of M1 and M2 macrophages in lower extremity arteriosclerosis obliterans (ASO). Methods: A rat model of lower extremity ASO was established, and blood samples from patients with lower extremity ASO before and after surgery were obtained. ELISA was used to detect interleukin 6 (IL-6), IL-10, and IL-17. Real-time RCR and Western blot analyses were used to detect Foxp3, IL-6, IL-10, and IL-17 expression. Moreover, flow cytometry was applied to detect the Th17/Treg ratio and M1/M2 ratio. Results: Compared with the control group, the iliac artery wall of ASO rats showed significant hyperplasia, and the concentrations of cholesterol and triglyceride were significantly increased (P<0.01), indicating the successful establishment of ASO. Moreover, the levels of IL-6 and IL-17 in ASO rats were pronouncedly increased (P<0.05), while the IL-10 level was significantly decreased (P<0.05). In addition to increased IL-6 and IL-17 levels, the mRNA and protein levels of Foxp3 and IL-10 in ASO rats were significantly decreased compared with the control group. The Th17/Treg and M1/M2 ratios in the ASO group were markedly increased (P<0.05). These alternations were also observed in ASO patients. After endovascular surgery (such as percutaneous transluminal angioplasty and arterial stenting), all these changes were significantly improved (P<0.05). Conclusions: The Th17/Treg and M1/M2 ratios were significantly increased in ASO, and surgery can effectively improve the balance of Th17/Treg, and reduce the ratio of M1/M2, and the expression of inflammatory factors.

ABSTRACT
Objective:To evaluate the clinical outcome of Robot-assisted sacroiliac screw fixation in the treatment of fragility fracture of the sacrum in the elderly.Methods:From March 2016 to June 2022, a retrospective analysis was performed on 30 patients with fragility fractures of the sacrum in the elderly who accepted robot-assisted sacroiliac screw to treat fragility fractures of the sacrum in our hospital. There were 12 males and 18 females with average age 71.03±8.25 years (range, 60-89 years). According to the classification of fragility fractures of the pelvis (FFP) in the elderly, there were 22 patients with FFP II, 2 patients with FFP III, and 6 patients with FFP IV. Surgical planning was based on the average CT value of S 1 channel and whether there is a transsacral screw channel. Robot-assisted sacroiliac screw fixation was performed during surgery. The pain of pre-operation and post-operation was evaluated using the visual analogue scale (VAS), the position of sacroiliac screws was evaluated by Gras grading, and the degree of functional recovery after surgery was evaluated using the Majeed function score. Results:All 30 patients successfully completed the operation. The mean operation time was 27.00±6.68 min (range, 18-35 min), the mean fluoroscopy times were 27.13±5.16 (range, 18-34), and the mean blood loss was 30.53±6.61 ml (range, 23-38 ml). All patients were followed up, and the mean follow-up time was 19.03±7.8 months (range, 8-25 months). The VAS was 5(5, 6), 4(3, 4), 3(2, 3), 0(0, 1) points before surgery, 1 week, 2 months and 6 months after surgery, respectively, and the difference was statistically significant ( H=103.26, P<0.001). After the surgery of 2 months, 6 months and the last follow-up time, the Majeed function scores were 88(83, 90), 91(87, 92), 92(90, 93) points, respectively, and the difference was statistically significant ( H=19.59, P<0.001). Screw position was evaluated according to Gras grading at 3 days after surgery, including 28 cases of level I, 2 cases of level II, and no screw penetrated the cortical bone or entered the sacral canal or sacral foramen. No vascular or nerve injury occured during the operation. 28 patients with FFS met the fracture healing criteria, and the healing time was 4.54±1.57 months (range, 3-7 months). Two patients had bone nonunion, one of whom underwent anterior ring plate removal due to infection of the pelvic anterior wound, and one month later, pelvic CT scan revealed loosening of the sacroiliac screw; the other one is considered to be related to too early weight bearing. Conclusion:For fragility fractures of the sacrum in elderly, Robot-assisted sacroiliac screw is an effective minimally invasive treatment, with high accuracy of screw placement, effective pain reduction, improved fracture healing rate, and achieve the satisfactory clinical efficacy.
ABSTRACT
The suitable habitat for the endangered and valuable medicinal herb Panax ginseng is gradually decreasing. It is crucial to investigate its suitable growing areas in China for global protection and sustainable utilization of P. ginseng. In this study, 371 distribution points of P. ginseng were collected, and 21 environmental factors were used as ecological indicators. The geographic information system for global medicinal plants(GMPGIS) system, MaxEnt model, and Thiessen polygon method were used to analyze the potential suitable areas for P. ginseng globally. The results showed that the key environmental variables affecting P. ginseng were precipitation in the hottest quarter(Bio18) and the coefficient of temperature seasonality(Bio4). The suitable habitats for P. ginseng were mostly located in the "One Belt, One Road" countries such as China, Japan, South Korea, North Korea, and Russia. The highly suitable habitats were mainly distributed along mountain ranges in southeastern Shandong, southern Shanxi and Shaanxi, northern Jiangsu, and northwestern Henan of China. Data analysis indicated that the current P. ginseng planting sites were all in high suitability zones, and the Thiessen polygon results showed that the geographic locations of P. ginseng production companies were unbalanced and urgently needed optimization. This study provides data support for P. ginseng planting site selection, scientific introduction, production layout, and long-term development planning.

Abstract Voriconazole increases tacrolimus blood concentration significantly when coadministrated. The recommendation of reducing tacrolimus to 1/3 in voriconazole package insert seems not to be satisfactory in clinical practice. In vitro studies demonstrated that the magnitude of inhibition depends on the concentration of voriconazole, while voriconazole exposure is determined by the genotype status of CYP2C19. CYP2C19 gene polymorphism challenges the management of drug-drug interactions(DDIs) between voriconazole and tacrolimus. This work aimed to predict the impact of CYP2C19 polymorphism on the DDIs by using physiologically based pharmacokinetics (PBPK) models. The precision of the developed voriconazole and tacrolimus models was reasonable by evaluating the pharmacokinetic parameters fold error, such as AUC0-24, Cmax and tmax. Voriconazole increased tacrolimus concentration immediately in all population. The simulated duration of DDIs disappearance after voriconazole withdrawal were 146h, 90h and 66h in poor metabolizers (PMs), intermediate metabolizers (IMs) and extensive metabolizers(EMs), respectively. The developed and optimized PBPK models in this study can be applied to assit the dose adjustment for tacrolimus with and without voriconazole.

OBJECTIVES@#To investigate the levels of physical growth and neurodevelopment in preterm infants at the corrected age of 18-24 months.@*METHODS@#The physical growth data and neurodevelopment data of 484 preterm infants at corrected age of 18-24 months were prospectively collected by a post-discharge follow-up system for preterm infants. The infants were regularly followed up in Shenzhen Bao'an Maternal and Child Health Hospital Affiliated to Jinan University from April 2018 to December 2021. The neurodevelopment was evaluated by the Children Neuropsychological and Behavioral Scale-Revision 2016. A total of 219 full-term infants served as controls. The infants were divided into groups (extremely preterm, very preterm, moderate late preterm, and full-term) based on gestational age, and the groups were compared in the levels of physical growth and neurodevelopment.@*RESULTS@#Except that the moderate preterm group had a higher length-for-age Z-score than the full-term group (P=0.038), there was no significant difference in physical growth indicators between the preterm groups and the full-term group (P>0.05). Each preterm group had a significantly lower total developmental quotient (DQ) than the full-term group (P<0.05). Except for the social behavior domain, the DQ of other domains in the extremely preterm and very preterm groups was significantly lower than that in the full-term group (P<0.05). The <32 weeks preterm group had a significantly higher incidence rate of global developmental delay than the full-term group (16.7% vs 6.4%, P=0.012), and the incidence rate of global developmental delay tended to increase with the reduction in gestational age (P=0.026).@*CONCLUSIONS@#Preterm infants can catch up with full-term infants in terms of physical growth at the corrected age of 18-24 months, but with a lower neurodevelopmental level than full-term infants. Neurodevelopment monitoring and early intervention should be taken seriously for preterm infants with a gestational age of <32 weeks.

OBJECTIVES@#Insulin signaling pathway plays an important role in metabolic associated fatty liver disease (MAFLD), however, the association between polymorphisms of genes related to insulin signaling pathway and MAFLD remains unclear. This study aims to investigate the association between insulin signaling pathway-related gene polymorphisms and gene-gene interactions with MAFLD susceptibility in obese children so as to provide scientific basis for further study of genetic mechanism.@*METHODS@#A total of 502 obese children with MAFLD who admitted to Hunan Provincial Children's Hospital from September 2019 to October 2021, were recruited as a case group, and 421 obese children with non-MAFLD admitted during the same period were recruited as a control group. Socio-demographic information, preterm birth history, eating habits, and exercise status of the subjects were collected by inquiry survey, and anthropometric information was collected by physical measurement. At the same time, 2 mL of venous blood was collected to extract DNA, and the polymorphism of insulin signaling pathway-related genes (5 representative candidate genes, 12 variants) was detected. Multivariate Logistic regression analysis was used to investigate the association between insulin signaling pathway-related gene polymorphisms and MAFLD in obese children.@*RESULTS@#After adjusting for confounder factors, INS rs3842748 was significantly associated with the risk of MAFLD in obese children in allele, heterozygous, and dominant models [OR and 95% CI 1.749 (1.053 to 2.905), 1.909 (1.115 to 3.267), 1.862 (1.098 to 3.157), all P<0.05]; INS rs3842752 was significantly associated with the risk of MAFLD in obese children in heterozygous and dominant models [OR and 95% CI 1.736 (1.028 to 2.932), 1.700 (1.015 to 2.846), all P<0.05]. NR1H3 rs3758674 was significantly correlated with the risk of MAFLD in obese children in allele model [OR and 95% CI 0.716 (0.514 to 0.997), P<0.05]. SREBP-1c rs2297508 was significantly associated with the risk of MAFLD in obese children in allele and dominant models [OR and 95% CI 0.772 (0.602 to 0.991) and 0.743 (0.557 to 0.991), all P<0.05]. SREBP-1c rs8066560 was significantly associated with the risk of MAFLD in obese children in allele, heterozygous, and dominant models [OR and 95% CI 0.759 (0.589 to 0.980), 0.733 (0.541 to 0.992), 0.727 (0.543 to 0.974), all P<0.05]. NR1H3 rs3758674 mutant C and SREBP-1c rs2297508 mutant G had interaction in the development of MAFLD in obese children [OR and 95% CI 0.407 (0.173 to 0.954), P<0.05].@*CONCLUSIONS@#The INS, NR1H3, and SREBP-1c gene polymorphisms in the insulin signaling pathway are associated with the susceptibility of MAFLD in obese children, but the functions and mechanisms of these genes need to be further studied.

This paper reviews the status quo of recent years’ research on autophagy and damage of chondrocytes in Kashin-Beck disease (KBD) and osteoarthritis (OA). PI3K/AKT signaling pathway and mTOR regulate the autophagy activity of chondrocytes. PI3K/AKT signaling pathway can promote the proliferation of chondrocytes and cause their damage by inhibiting their autophagy activity. This might play an important role in the occurrence and progression of bone and joint diseases such as KBD and OA, and provide scientific basis for revealing the pathogenesis and treatment plan of them.

ABSTRACT
Objective:To explore the effect of play-based communication and behavior intervention (PCBI) on internalizing and externalizing behaviors in children with autism spectrum disorder (ASD).Methods:From November 2018 to November 2021, 90 ASD children aged 8-30 months who registered in the Child Mental Health Research Center of the Affiliated Brain Hospital of Nanjing Medical University for PCBI ultra-early intervention training were selected and randomly assigned to the intervention group( n=60) and the waiting group( n=30) according to the ratio of 2∶1.Behavioral videos of free play between children and caregivers were collected before and after the 12-week intervention and the behavioral observation and analysis system (Observer XT) was used to code the parent-child interaction status and children's internalizing and externalizing behaviors.SPSS 23.0 statistical software were used and the data were analyzed by t-test, chi-square test, Pearson correlation analysis and multiple linear stepwise regression analysis. Results:After the intervention, the children in the intervention group had improved internalizing and externalizing behaviors (2.43±2.22, 1.88±1.91) compared with those before the intervention (4.82±3.37, 3.68±5.68), and the difference was statistically significant ( t=4.66, 2.60, both P<0.05). The children in the waiting group had no significant difference in internalizing and externalizing behaviors before (4.23±2.47, 4.00±2.18) and after intervention (4.37±2.57, 4.67±3.72) ( t=-0.23, -0.83, both P>0.05). After intervention, the children in the intervention group had fewer internalizing and externalizing behaviors than those in the waiting group, and the difference was statistically significant ( t=-3.70, -4.71, both P<0.05). The differences in internalizing behaviors (2.38±3.96, 1.80±5.37) and externalizing behaviors (1.80±5.37, -0.67±4.38) between the two groups before and after the intervention were statistically significant ( t=3.03, 2.18, both P<0.05). The results of multiple linear stepwise regression showed that the negative interaction of caregivers ( β=0.29, P<0.01) was a risk factor for internalizing behaviors.The negative interaction of children ( β=0.45, P<0.01) was a risk factor for externalizing behaviors, and the child's object status ( β=-0.30, P<0.01) and binary interaction ( β=-0.39, P<0.01) were protective factors for externalizing behaviors.In the intervention group, active child interaction, active caregiver interaction, and binary interaction increased after the intervention ( t=-6.77, -4.58, -7.72, all P<0.05), while the child's object status and the caregiver's negative interaction decreased ( t=3.37, 4.30, both P<0.05). Conclusion:The PCBI ultra-early intervention can effectively improve the internalizing and externalizing behaviors of ASD children.Improvements in internalizing behaviors may work by reducing negative caregiver interactions, and improvements in externalizing behaviors may work by increasing parent-child binary interactions.

ABSTRACT
OBJECTIVE@#To study whether there are differences in the resuscitation process and early outcomes between the extremely preterm infants delivered on off-hours (6 pm to 8 am of working days, weekends, and national holidays) and those delivered on working hours.@*METHODS@#A retrospective analysis was performed on the medical data of extremely preterm infants who were born in the Peking University Third Hospital from January 1, 2010 to December 31, 2020 and transferred to the neonatal intensive care unit (NICU). According to the time of birth, they were divided into two groups:working hours (@*RESULTS@#Compared with the working hours group, the off-hours group had a significantly lower proportion of infants with the use of full-dose dexamethasone before delivery (@*CONCLUSIONS@#Extremely preterm infants delivered on off-hours tend to have a low Apgar score at 1 minute after birth, with a higher proportion of infants requiring positive pressure ventilation or tracheal intubation during resuscitation than those delivered on working hours, and they tend to develop neonatal respiratory distress syndrome and intrauterine pneumonia. This suggests that it is important to make adequate preparations in terms of personnel and supplies for resuscitation of extremely preterm infants after birth and that NICUs should develop a detailed management plan for extremely preterm infants at each period of time before, during, and after birth.

Chondroitin sulfate (CS) is a sulfurated glycosaminoglycan, a major component of the extracellular matrix, widely distributed in skin, cartilage and vascular tissue. CS plays an important role in the physiological state regulation of articular cartilage, which affects tensile strength and elasticity of tissues by influencing aggrecan. Previous studies have shown that CS sulfate modification may be related to the growth and development disorders of cartilage tissue and the occurrence of osteoarticular diseases. At the same time, CS is also a common joint supplement, often used in the treatment of osteoarthritis and Kashin-Beck disease. In this paper, the research progress of CS sulfate modification characteristics in Kashin-Beck disease and osteoarthritis and the application of the preparation in the treatment of Kashin-Beck disease and osteoarthritis are reviewed, aiming to provide help for the investigation of the etiology of Kashin-Beck disease and the treatment of osteoarthritis and Kashin-Beck disease.
ABSTRACT
Quench of magnetic resonance imaging system refers to the process that the superconducting condition inside the magnet is destroyed due to some reason. The large current stored in the coil is quickly converted into heat at the place where the resistance is formed, and a large amount of liquid helium in the magnet is evaporated. If it happens, it will cause huge loss to the user. We introduce the real cases of 1.5 T magnetic resonance imaging system's quench fault, maintenance treatment and management improvement, which can be used for reference by various medical institutions, so as to better strengthen the operation and maintenance management of magnetic resonance imaging system, so as to avoid the occurrence of out of tolerance fault, and do a good job in the guarantee work after the out of tolerance fault.

C2H2 transcription factors play an important role in plant growth, development and the regulation of secondary metabolism. This article identifies members of the C2H2 gene family in Cannabis sativa L. at the genome level. Chromosomal location and linkage, evolutionary relationships, and identification of conserved motifs was determined from the C. sativa genome and transcriptome data using bioinformatics tools and on-line websites such as TBtools, MEGA software, NCBI, PlantTFDB, ExPASy, HMMSCAN, MEME, WoLFPSORT and PlantCARE. The results show that C. sativa contains 30 members of the C2H2 gene family (named CsC2H2-1-CsC2H2-30) distributed on 9 chromosomes. The encoded proteins range in length from 138 to 635 amino acids, and the theoretical isoelectric points range from 5.85 to 9.52. Molecular weights range from 15 909.48 to 68 445.53 Da. Transcriptome analysis showed that CsC2H2 was differentially expressed in the female flowers, bracts, leaves, and stems of the Diku variety and female flowers of nine different varieties of C. sativa. Quantitative real-time PCR verified that CsC2H2-1, CsC2H2-5, and CsC2H2-19 were significantly expressed in the female flowers and bracts of the Diku variety. This provides a theoretical basis for in-depth study of the function of the C2H2 gene family and the breeding of high-quality C. sativa varieties.
ABSTRACT
BACKGROUND@#Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis.@*METHODS@#We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician's global assessment (sPGA) at week 12.@*RESULTS@#The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported.@*CONCLUSION@#During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry (ChiCTR), ChiCTR-TRC-13003259; http://www.chictr.org.cn/showprojen.aspx?proj=6300.

LBD(lateral organ boundaries)transcription factors play an important role in the regulation of plant growth, development and secondary metabolism. In order to explore the function of LBD genes in cannabis, the Cannabis sativa genome and transcriptome were used to identify the C. sativa LBD gene family, and analyzed their expression patterns. Our results showed that the cannabis LBD contains 32 members, which were divided into two major categories, seven sub-families. Class Ⅰ was divided into 5 sub-families, named Class Ⅰ_a to Class Ⅰ_e, while Class Ⅱ was divided into 2 sub-families, including Class Ⅱ_a and Class Ⅱ_b. Analysis showed that the number of amino acids encoded LBDs was between 172 and 356, and the isoelectric point was between 4.92 and 9.43. The mole-cular weight of LBD was between 18 862.92 Da and 40 081.33 Da, and most members are located in the nucleus. Chromosome positioning of LBD showed that 32 members were unevenly distributed on 10 chromosomes of C. sativa LBD transcription factor domain, gene structure and motifs are relatively conservative, and the characteristics of different class members are similar. The upstream promoter region of the gene contains a variety of cis-acting elements related to plant hormones and environmental factors, C. sativa LBD genes have different expression patterns in the stems, leaves, and flowers of ZYS varieties(low tetrahydrocannabinol, high cannabidiol). The members of the LBD gene family are mainly expressed in the flowers and stems of ZYS varieties, while members expressed in the leaves very few; Class Ⅱ members CsLBD21 and CsLBD23 are expressed in flowers and stems, and CsLBD8 and CsLBD18 are expressed in flowers, stems and leaves. These genes may participate in the growth and development of cannabis and affect the biosynthesis of cannabinoids. This study laid the foundation for the subsequently functional research of the cannabis LBD gene family.

A total of 170 neonates with hyperbilirubinemia but without readmission during the same period of time were randomly selected as the control group. The medical data were compared between the two groups. Multivariate logistic regression was used to assess the risk factors for readmission due to hyperbilirubinemia.@*RESULTS@#The readmission rate was 2.30%, and the interval between readmission and initial admission was 5 days. Compared with the control group, the study group had significantly higher levels of total bilirubin and indirect bilirubin at discharge (P<0.05) and a significantly longer duration of phototherapy during the first hospitalization (P<0.05). The univariate analysis showed that compared with the control group, the study group had significantly lower birth weight, gestational age, and age on initial admission (P<0.05) and a significantly higher proportion of infants with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency or hemolytic disease (P<0.05). The multivariate analysis showed that low gestational age (OR=1.792, P<0.05), young age on initial admission (OR=1.415, P<0.05), and G-6-PD deficiency (OR=2.829, P<0.05) were independent risk factors for readmission of neonates with hyperbilirubinemia.@*CONCLUSIONS@#The infants with hyperbilirubinemia who have lower gestational age, younger age on initial admission, and G-6-PD deficiency have a higher risk of readmission due to hyperbilirubinemia. It is thus important to strengthen the management during hospitalization and after discharge for these infants to prevent the occurrence of readmission.
