Based on the "sweat pore-qi and liquid-collaterals" theory， it is considered that the core pathogenesis of pediatric infectious mononucleosis lies in the obstruction of sweat pores， the failure of qi and liquid to disperse， and damage to the collaterals due to pathogenic toxins. Accordingly， the treatment principles proposed include unblocking the sweat pores， regulating qi and liquid， and smoothing the collaterals. In clinical practice， treatment is differentiated according to stages： initial， acute， and late stages. In the initial stage， invasion of warm pathogenic toxins into the lung defense leads to obstruction of the sweat pores， which should be treated by unblocking the sweat pores and expelling pathogens outward. In the acute stage， the obstruction of the sweat pores worsens， leading to the failure of qi and liquid dispersal， resulting in intense heat toxins with accumulation of dampness， phlegm， and blood stasis， which should be treated by promoting qi movement， resolving dampness and phlegm， clearing heat， detoxifying， and dispersing stasis to regulate qi and liquid. In the late stage， residual pathogens remain， with qi and yin deficiency and unsmooth collaterals， which should be treated by unblocking the collaterals， dissipating nodules， tonifying qi， and nourishing yin to smooth the collaterals. This approach may provide new insights for the clinical treatment of pediatric infectious mononucleosis.

AIM: To compare the agreement between the ARK Biometer Combo and OA 2000 in patients wearing orthokeratology lenses.METHODS: A prospective study. A total of 148 patients(148 eyes)who were wearing orthokeratology lenses and returned for follow-up at the Shanghai Eye Disease Prevention and Treatment Center from August to September 2024 were included. Biometric measurements were performed using both the ARK Biometer Combo and OA 2000. Parameters including axial length(AL), corneal central thickness(CCT), anterior chamber depth(ACD), lens thickness(LT), corneal curvature(Kf and Ks), astigmatism(AST), white-to-white corneal diameter(WTW)and pupil diameter(PD)were obtained. Differences in measurement parameters between the two biometers were compared, and agreement was assessed.RESULTS: There were no statistically significant differences in the measurements of Kf, Ks and AST between the two biometers(P>0.05). Statistically significant differences were found in the measurements of AL, CCT, ACD, LT, WTW and PD(t=2.559, P=0.012; t=16.771, P<0.0001; t=4.749, P<0.0001; t=-15.212, P<0.0001; t=-14.915, P<0.0001; t=-2.402, P=0.018). ICC ranged from 0.615 to 0.999. Bland-Altman analysis showed that the maximum absolute values of the 95% limits of agreement(LoA)of AL, CCT, ACD, LT, Kf, Ks, AST, WTW and PD were 0.07 mm, 35.07 μm, 0.07 mm, 0.12 mm, 0.66 D, 1.14 D, 1.00 D, 0.76 mm, and 0.98 mm, respectively.CONCLUSION: In orthokeratology patients, the ARK Biometer Combo and OA 2000 showed good agreement in measuring AL, CCT, ACD, Kf and LT, and can be used interchangeably.

Objective: To investigate the relationship of metabolic score for insulin resistance (METS-IR) with bone mineral content (BMC) and bone metabolic markers levels among adolescents, so as to provide a scientific foundation for the early identification and prevention of bone related diseases. Methods: From 2017 to 2019 and 2023, a total of 1 414 adolescents aged 12-18 years from Yinchuan were selected using a method combining convenient sampling with stratified cluster random sampling. The data of basic information, body mass index, BMC, serum osteocalcin (OC), type I collagen cross linked C-terminal peptide (CTX) and calcium (Ca), METS-IR among adolescents were obtained by questionnaire survey, physical measurement and laboratory examination,and METS-IR was divided into four groups Q1-Q 4 according to P 25 , P 50 and P 75 . Logistic regression models combined with restricted cubic splines were employed to analyze the relationship between METS-IR and low BMC as well as low bone metabolic markers. The receiver operating characteristic (ROC) curve was used to evaluate METS-IR effectiveness in diagnosing low BMC. Results: The levels of BMC, OC, CTX, Ca and METS-IR in the surveyed adolescents were (2.66±0.52)kg, (20.49±13.77) ng/mL , (2 460.89±1 818.96)pg/mL, (2.47±0.67)mmol/L, 30.63±7.58. After adjusting for gender, age and physical activity level, METS-IR in Q 4 group had a reduced risk of low BMC and low CTX [ OR (95% CI )=0.03(0.01-0.07), 0.45(0.32-0.65)] and an elevated risk of low OC [ OR (95%CI )=1.85(1.28-2.67)], compared with the Q 1 group (all P <0.05). Gender stratified analyses revealed similar trends for both males and females (all P <0.05). Non linear dose response relationships were observed between METS-IR and low BMC ( P total trend <0.01, P non linearity =0.01), as well as low OC ( P total trend <0.01, P non linearity =0.01), while a linear relationship was detected with low CTX ( P total trend <0.01, P non linearity =0.72). ROC curves revealed that METS-IR had the best diagnostic performance for low BMC (AUC=0.85, 95% CI=0.82-0.88, P <0.01). Conclusions Higher METS-IR score is linked to reduced risk of low BMC and CTX but increase risk of low OC among adolescents. These findings suggest METS-IR is a reliable indicator for assessing BMC and early predicting bone health risk among adolescents.

Guided by the theory of "mutual dependence of ascending and descending"， recurrent pediatric cough and asthma are considered to result from the imbalance of the ascending and descending of zang-fu organ qi， which is closely associated with deficiency， phlegm， and blood stasis. In clinical practice， the disease is treated based on differentiation during the initial stage， progression stage， and stable stage. In the initial stage， the pathogenesis is attributed to lung deficiency complicated by external pathogens and liver qi rising to attack the lung； the treatment should focus on restraining the lung and calming the liver， using the self-formulated Longchai Yuchuan Fomulation （龙柴愈喘方）. During the progression stage， the disorder is due to the spleen failing to ascend clear qi and the kidney failing to grasp qi， leading to phlegm formation from deficiency； treatment should focus on tonifying spleen yang， supplementing kidney qi， and resolving phlegm and fluid retention， using a modified combination of Linggui Zhugan Decoction （苓桂术甘汤） and Jinkui Shenqi Pill （金匮肾气丸）. In the stable stage， qi deficiency leads to poor consolidation， with phlegm turbidity and blood stasis； the treatment should aim at tonifying qi， transforming phlegm， and dispelling blood stasis， using a modified version of Guizhi Fuling Pill （桂枝茯苓丸）.

Salmonellosis represents a global epidemic, and the emergence of extensively drug-resistant (XDR) Salmonella and its sustained transmission worldwide constitutes a significant public health concern. Flagellum-mediated motility serves as a crucial virulence trait of Salmonella that guides the pathogen toward the epithelial surface, enhancing gut colonization. Artemisia argyit essential oil, a traditional herb extract, demonstrates efficacy in treating inflammation-related symptoms and diseases; however, its effects on flagellum assembly and expression mechanisms in anti-Salmonella activity remain inadequately explored. This study aimed to elucidate the mechanism by which Artemisia argyit essential oil addresses Salmonella infections. Network pharmacological analysis revealed that Traditional Chinese Medicine (TCM) Artemisia argyit exhibited anti-Salmonella infection potential and inhibited flagellum-dependent motility. The application of Artemisia argyit essential oil induced notable motility defects through the downregulation of flagellar and fimbriae expression. Moreover, it significantly reduced Salmonella-infected cell damage by interfering with flagellum-mediated Salmonella colonization. In vivo studies demonstrated that Artemisia argyit essential oil administration effectively alleviated Salmonella infection symptoms by reducing bacterial loads, inhibiting interleukin-1 beta (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α) production, and diminishing pathological injury. Gas chromatography-mass spectrometry (GC-MS) analysis identified forty-three compounds in Artemisia argyit essential oil, with their corresponding targets and active ingredients predicted. Investigation of an in vivo model of Salmonella infection using the active ingredient demonstrated that alpha-cedrene ameliorated Salmonella infection. These findings suggest the potential application of Artemisia argyit essential oil in controlling Salmonella, the predominant food-borne pathogen.

Objective:To improve the understanding of acute lymphoblastic leukemia (ALL) secondary to Burkitt lymphoma (BL) in children.Methods:The clinical data of a child with ALL secondary to BL who was admitted to Children's Hospital Affiliated to Zhengzhou University in June 2024 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a boy with the age of 8 years and 8 months. He presented with a neck mass at the age of 4 years and 6 months, and pathological examination revealed a diagnosis of BL with clinical stage Ⅲ. The patient was given regular chemotherapy according to the Chinese Children's Lymphoma Group non-Hodgkin lymphoma mature B-cell 2017 protocol-B2 regimen. PET-CT showed recurrence of lymphoma in 6 months after the suspension of treatment. The patient was given with placement of 125I particles, oral etoposide and dexamethasone, and traditional Chinese medicine. The patient was admitted to hospital at the age of 8 years and 8 months with fever and skin hemorrhagic spots, bone marrow morphology, immunology, cytogenetics and molecular biology typing indicated a diagnosis of B-ALL with TCF3::PBX1 fusion gene. The patient received induction chemotherapy according to the Chinese Children's Leukemia Group-ALL 2018 protocol. A review of bone marrow cytology achieved complete remission on the 33rd day of chemotherapy, and minimal residual disease detected by flow cytometry indicated less than 0.01%. TCF3::PBX1 fusion gene was negative. Conclusions:ALL secondary to BL in children is rare, and the ALL treatment regimens are effective.

Using conventional broth microdilution assays,the synthetic phenolic antioxidant 2,6-di-tert-butyl-4-methylphenol(butylated hydroxytoluene,BHT)was screened for synergistic antimi-crobial activity with β-lactam antibiotics.Further validation through checkerboard assays,growth curve analysis,and time-kill curve experiments confirmed the synergistic effect of BHT and β-lac-tams against methicillin-resistant Staphylococcus aureus(MRSA)(FICI≤0.5).To elucidate the underlying mechanism of synergy,this study evaluated changes in membrane permeability and pro-ton transmembrane gradients-key factors in biofilm functionality-along with critical indicators of bacterial energy metabolism,including ATP levels and the NAD+/NADH ratio.The results dem-onstrated that BHT disrupts the proton motive force(PMF),impairs membrane potential,and perturbs bacterial energy homeostasis,thereby significantly enhancing the antibacterial efficacy ofβ-lactams.Furthermore,a murine pneumonia infection model was established to assess the in vivo therapeutic efficacy of BHT combined with amoxicillin.The combination therapy alleviated pulmo-nary tissue damage,reduced bacterial loads in target organs(liver,spleen,and lungs),and decreased systemic inflammatory responses.This study elucidates the synergistic antimicrobial action and mechanistic basis of BHT combined with amoxicillin,offering a novel combinatorial therapeutic strategy to address MRSA resistance.The findings hold significant clinical potential and research value for overcoming antibiotic resistance in MRSA infections.
