Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Central precocious puberty (CPP) is an endocrine disease of children due to the early onset of hypothalamic-pituitary-gonadal axis function. This leads to increased secretion of gonadotropin release impulse, causing the development of internal and external genitalia and the presentation of secondary sex characteristics. Studies have found that the onset of CPP in children may be related to vitamin D deficiency. Vitamin D, affected by sunlight duration, acts on neurons and neurotransmitters in the hypothalamic-pituitary-gonadal axis, promotes obesity and affects the expression level of insulin-like growth factor-1, which are four factors involved in the occurrence and development of CPP. The overall effect of vitamin D combined with gonadotropin-releasing hormone analogues on CPP is significant. This article reviews the correlation between vitamin D deficiency and CPP, as well as the possible mechanism of action, in order to provide some theoretical basis for researchers.

Objective:This study was aimed to analyze the untargeted metabolomics of serum samples from children with mycoplasma pneumonia in a hospital in Beijing.Methods:A total of 50 children with mycoplasma pneumonia as the case group were recruited from Department of Pediatrics, China-Japan Friendship Hospital in Beijing from January 2019 to February 2020, and meanwhile 50 age-and gender-matched heathy children were selected and formed the control group. 2 ml venous fasting blood samples was collected from all children. Serum metabolites were quantified by using the untargeted ultra-high performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) technique. Unsupervised principle component analysis and (orthogonal) partial least-squares-discriminant analysis were employed to identify differential metabolites between cases and controls. MBRole software was used for pathway enrichment analysis.Results:There were 27 boys and 23 girls in the case group with an average age of (6.0±3.65) years, and the control group consisted of 28 boys and 22 girls with an average age of (6.62±2.64) years. A total of 392 different metabolites were detected. Compared with the control group, 306 metabolites were decreased and 86 increased in case group. Forty-one differential metabolites with variable important in projection (VIP) values larger than 5 and P values less than 0.05 were teased out, and they mainly concentrated on phospholipid. The levels of 38 metabolites were significantly lower in the case group, yet 4 metabolites were significantly higher than that of the control group. Metabolic enrichment analysis showed that different metabolites were related to the biosynthesis of phenylalanine, tyrosine, tryptophan, unsaturated fatty acid, ammonia acyl tRNA and insulin signaling pathway, as well as the metabolism of ABC transporters. Conclusion:The serum untargeted metabolomics differed remarkably between children with mycoplasma pneumonia and healthy children.

Hypoxic-ischemic encephalopathy is a leading cause of acquired neonatal brain injury and may lead to long-term neurological sequelae or death. Early and professional assessment of neurobehavior with appropriate tools facilitates identifying critical influencing factors within the neonatal period and providing specific guidance and determining management and prognosis. This review summarized the neurobehavior assessment tools at home and abroad within the neonatal period, aiming to provide a reference for clinical practice and research.

Breastfeeding, as the optimal feeding pattern, ensures the physical, neurological and psychological growth and development of infants. Professional evaluation of breastfeeding with assessment tools facilitates identifying critical influencing factors and providing specific guidance and health education. This review summarized the breastfeeding assessment tools at home and abroad to provide reference for clinical practice and research.

Objective To evaluate the echocardiographic features of coronary artery dilation (CAD) and coronary artery aneurysms (CAA) in Kawasaki disease dynamically.Methods Echocardiography was performed in KD cases for measurement of the diameter of the coronary artery.Results Twelve CAD and four CAA were identified in forty-one patients.In CAD group,left coronary artery (LCA) is more susceptive to dilation than right coronary artery (RCA)(P<0.05).Both LCA and RCA were involved in CAA group,the maximum diameter of coronary artery is 10mm.Six to eighteen days after treatment,LCA were regressed significantly in CAD group(P<0.05),but the diameter of RCA in CAD group and coronary artery in CAA patients have no change(P>0.05).Ten coronary artery lesion patients were followed up,8 CAD cases regressed completely,1 CAA extended,the other CAA regressed completely.Conclusions In CAD group,LCA is more susceptive to dilation than RCA,but it regressed significantly in a short time after treatment.Echocardiography is a non-traumatic method to detect the coronary artery lesions in KD patients dynamically.

Objective To investigate the clinical features of incomplete Kawasaki disease (IKD).Methods The data of 46 Kawasaki disease (KD) patients including 14 IKD patients (IKD group)and 32 classical Kawasaki disease (CKD) patients (CKD group) was analyzed retrospectively,and compared the clinical manifestation,laboratory examination result,the incidence of coronary artery lesion (CAL) and the response to intravenous immunoglobulin (IVIG) of two groups.Results There was no significant difference in gender and age between IKD group and CKD group (P> 0.05 ).In IKD group,the fever time was longer than that in CKD group [( 11.43 ± 9.12) d vs (7.12 ± 2.83 ) d, P < 0.05], but the frequency of conjunctival congestion, lymphadenectasis of neck, indurative edema of palms and soles, changes of lips and oral cavity were less than these in CKD group [57.14%(8/14) vs 93.75%(30/32),28.57%(4/14) vs 59.38%(19/32), 35.71%(5/14) vs 78.12%(25/32),42.86%(6/14) vs 75.00%(24/32)](P< 0.01 or < 0.05).There was no difference in laboratory examination result and incidence of CAL between two groups, but the incidence of IVIG nonresponse in IKD group was higher than that in CKD group [40.0%(4/10) vs 6.45%(2/31 ),P <0.05].Conclusions The frequency of conjunctival congestion, indurative edema of palms and soles, changes of lips and oral cavity are less common in IKD patients comparing with CKD patients.The laboratory examination result and the risk of CAL in IKD patients are similar to CKD ones.Moreover, IKD is not sensitive to IVIG, so the doctors should pay more attention to it.
