    Abstract Background: Jaffe-Campanacci syndrome (JCS) is a very rare syndrome. The treatment of JCS is more conservative, and most authors recommend that no surgery should be done in asymptomatic patients. The conventional concept holds that the natural course of non-ossifying fibromas (NOFs) grows with the development of bones, and the osteolytic region gradually stops expanding and self-healing through bone ossifying around the lesion and ossification within the lesion. But in this case, the bone lesions were potentially biologically aggressive, which led to severe limb deformities and pain.
    Case summary: We present the case of a 5-year-old girl with JCS presenting with not only NOF sand café-au-lait macules, but also showed features not mentioned before, severe limb pain, and at last resulted in amputation. She was admitted to our hospital after presenting with claudication and mild pain over her right thigh, which worsened when stretching or being touched. Skin examination revealed multiple café-au-lait macules on the neck, arm, axilla, and torso, including the nipples and perineum. Radiographs revealed multiple lytic lesions in the proximal part of the right humerus, distal part of the right clavicle, proximal and distal parts of the right femur, and proximal parts of the right tibia and fibula. Curettage and biopsy were performed on the distal part of the right femur. At the age of 7, the girl was re-admitted to our hospital for a pathological fracture in the middle in the right femur and underwent Intralesional excision, internal fixation, bone grafting, and spica casting. At the age of 10, the girl came to our hospital again for severe pain of the right leg. Amputation from the middle level of the right femur was performed. We present the case of a 5-year-old girl with JCS presenting with not only NOFs and café-au-lait macules, but also showed features not mentioned before, severe limb pain, and at last resulted in amputation. She was admitted to our hospital after presenting with claudication and mild pain over her right thigh, which worsened when stretching or being touched. Skin examination revealed multiple café-au-lait macules on the neck, arm, armpit, and torso, including the nipples and perineum. Radiographs revealed multiple lytic lesions in the proximal part of the right humerus, distal part of the right clavicle, proximal and distal parts of the right femur, and proximal parts of the right tibia and fibula. Curettage and biopsy were performed on the distal part of the right femur.

At the age of 10, the girl came to our hospital again for severe pain of the right leg. Amputation from the middle level of the right femur was performed.
    Conclusion: In our opinion, education on preventing pathological fractures and explaining the consequent serious consequences to the parents is a matter of prime significance. At the same time, prophylactic treatment (restricted exercise, support, or surgery) is also considerable for JSC.

    Abstract Extracellular vesicles (EV),nanoscale vesicles encapsulated by phospholipid bilayers,are rich in biological molecules such as nucleic acids,metabolites,proteins,and lipids derived from parental cells.They are mainly involved in intercellular communication,signal transmission,and material transport and affect the functions of target cells.Ovulation disorders account for a higher proportion in the factors causing infertility which demonstrates increasing incidence year by year.Non-coding RNAs participate in a series of physiological and pathological processes of follicular development,playing a key role in female infertility.This review systematically introduces the types and biological roles of EV and elaborates on the regulation of follicular development from the effects of EV and non-coding RNAs on granulosa cell function,oocyte maturation,ovulation,luteal formation,and steroid hormone synthesis,providing a new idea and a breakthrough point for the diagnosis and treatment of infertility.

    Abstract Objective: To evaluate ocular changes in Chinese myopic children wearing multifocal soft contact lenses and explore their efficiency and related factors.
    Method: This was a prospective, double-blind, randomized controlled study. A total of 36 myopic children aged 7 to 12 years were randomly divided into groups wearing multifocal soft contact lenses (MFCLs) or single-vision soft contact lenses (SVCLs) and followed up for 12 months. The spherical equivalent (SE), axial length (AL), choroidal thickness, and vascularity were measured before commencement and after 6 and 12 months of lens wear. Correlation between ocular changes and myopia progression was determined.
    Results: A total of 32 subjects (6 males and 26 females) completed the study and were included in the analysis. After 12 months of lens wear, both the AL elongation (0.25±0.22 vs. 0.43±0.16 mm, P=0.011) and the SE progression (-0.69±0.69 D vs. -1.45±0.56 D, P=0.002) of the MFCL group were significantly lower than those of the SVCL group. After 12 months, the progression of myopia was significantly correlated with changes of the choroid in the MFCL wearers, whereas no such correlation was observed in the SVCL group.
    Conclusion: Multifocal soft contact lens can slow myopia progression, and this effect may be related to the changes of the choroid.

    Abstract Significance: This survey provides information about Chinese children's myopia correction status and parents' attitudes toward myopia correction.
    Purpose: Under the background of a guideline of appropriate techniques for the prevention and control of children's myopia, this study aimed to investigate the current myopia correction pattern of children and parents' attitudes.
    Methods: Two self-administered questionnaires were distributed to 684 children with myopia corrections and 450 parents (384 mothers and 66 fathers) to explore children's myopia correction patterns and parental attitudes. The questionnaire investigated the pattern of children's myopia correction, prescribing of children's myopia correction, the incidence of high myopia, parental attitudes toward various myopia corrections methods, and preferred initial age for contact lens usage.
    Results: Single-vision spectacles (n = 600; 88.2 ± 7.4%) are widely used in China because of their comfort and affordability. More than 80% of children use single-vision spectacles prescribed by ophthalmologists and opticians. Children who used single-vision spectacles at an earlier age had more incidence of high myopia (18.4 ± 4.2%) than those who used single-vision spectacles at a later age (0.7 ± 0.9%). Effective myopia control was the primary reason parents preferred to choose different optical corrections, followed by safety, convenience, clarity, affordability, comfort, and other reasons. The survey indicated that 52.4% of parents whose children used orthokeratology lenses would have preferred safe and convenient options if available. In addition, 50% of the parents preferred delaying their children's use of orthokeratology lenses and other contact lenses to an older age.
    Conclusions: Single-vision spectacles are still a popular option to correct myopia in children. There was a demonstrated increase in myopia in children who used single spectacles at an earlier age. Parents' attitudes were important factors for selecting myopia corrections in children.

    Abstract Cancer cells, endothelial cells, inflammatory cells and various cytokines form a part of the tumor microenvironment (TME). Chemokines constitute the largest family of cytokines, and are mainly secreted by tumor cells and inflammatory cells in the TME. They play an important role in tumor development and progression by promoting tumor growth and metastasis, angiogenesis, and targeting the chemoattraction of inflammatory cells. Currently, some chemokine receptor antagonists are being used in clinical trials as targeted anti-tumor drugs. In this article, we review the roles of chemokines in the development and progression of malignant tumors based on recently published papers, taking into consideration of the new anti-tumor therapeutic strategies targeting chemokines and receptors.

    Abstract Purpose: To investigate the effects of accommodation on the geometrical parameters of human lens.
    Methods: Eight databases from inception to November 2023 were used for the literature search: CNKI, CBM, VIP, Wan-Fang, PubMed, Web of Science, EMBASE, and the Cochrane Library. The Methodological Index for Non-randomized Studies was used to assess the risk of bias. The PRISMA were followed and the following outcomes were taken into consideration: lens diameter (LD), lens thickness (LT), anterior curvature radius (ACR), posterior curvature radius (PCR), lens center position (LCP), and total cross-sectional area (TCSA). This systematic review was registered on an international platform for registered systematic reviews and meta-analysis (INPLASY202260085).
    Results: A total of 19 studies were included. LT increased by 0.04 mm/D (18 studies; 95% confidence interval [CI], 0.03-0.06;
    Conclusions: Changes in LT, LD, ACR, PCR and LCP supported Helmholtz's theory. Different apparatuses or measurement methods influenced the measurement of lens geometrical parameters.

    Abstract Objective: The risk factors for respiratory insufficiency in children with Guillain-Barré syndrome (GBS) are poorly known. This study aimed to investigate the factors associated with respiratory insufficiency in children with GBS.
    Methods: This retrospective study included children diagnosed with GBS by pediatric neurologists and admitted at the Wuhan Children's Hospital and other hospitals from January 2013 to October 2022. The patients were divided into the respiratory insufficiency and nonrespiratory insufficiency groups according to whether they received assist breathing during treatment.
    Results: The median (interquartile range) age of onset of 103 patients were 5 (3.1-8.5) years, 69 (67%) were male, and 64 (62.1%) had a history of precursor infection. Compared with the nonrespiratory insufficiency group, the respiratory insufficiency group showed more facial and/or bulbar weakness (
    Conclusion: In conclusion, facial and/or bulbar weakness, HFGS at admission, and onset-to-admission interval were associated with respiratory insufficiency and might be useful prognostic markers in children with GBS.

    Abstract Detection sensitivity is a critical characteristic to consider during selection of spectroscopic techniques. However, high sensitivity alone is insufficient for spectroscopic measurements in spectrally congested regions. Two-color cavity ringdown spectroscopy (2C-CRDS), based on intra-cavity pump-probe detection, simultaneously achieves high detection sensitivity and selectivity. This combination enables mid-infrared detection of radiocarbon dioxide ([Formula: see text]CO[Formula: see text]) molecules in room-temperature CO[Formula: see text] samples, with 1.4 parts-per-quadrillion (ppq, 10[Formula: see text]) sensitivity (average measurement precision) and 4.6-ppq quantitation accuracy (average calibrated measurement error for 21 samples from four separate trials) demonstrated on samples with [Formula: see text]C/C up to [Formula: see text]1.5[Formula: see text] natural abundance ([Formula: see text]1,800 ppq). These highly reproducible measurements, which are the most sensitive and quantitatively accurate in the mid-infrared, are accomplished despite the presence of orders-of-magnitude stronger, one-photon signals from other CO[Formula: see text] isotopologues. This is a major achievement in laser spectroscopy. A room-temperature-operated, compact, and low-cost 2C-CRDS sensor for [Formula: see text]CO[Formula: see text] benefits a wide range of scientific fields that utilize [Formula: see text]C for dating and isotope tracing, most notably atmospheric [Formula: see text]CO[Formula: see text] monitoring to track CO[Formula: see text] emissions from fossil fuels. The 2C-CRDS technique significantly enhances the general utility of high-resolution mid-infrared detection for analytical measurements and fundamental chemical dynamics studies.

    Abstract Objective: To investigate the correlation of cardiac magnetic resonance imaging (MRI) in the assessment of myocardial activity in patients with myocardial infarction and the outcome of cardiac function after PCI. Methods: 30 patients with myocardial infarction (MI) who had complete clinical and imaging data from July 2016 to December 2018 after PCI were analyzed retrospectively. MR and echocardiogram were performed before and 6 months after PCI, and the parameters related to left ventricular function were measured by postprocessing software of MRI workstation. The left ventricular transmural degree of CMR late gadolinium enhancement was compared with the left ventricular wall motion degree of 6-month echocardiography as a standard to judge the viable myocardium. Result: There were 193 left ventricular segmental abnormalities in 30 cases, including 121 viable myocardium and 72 non viable myocardium in CMR-LGE before operation. Six months after PCI, echocardiography showed that 125 of 193 abnormal segments of left ventricle detected by CMR-LGE before PCI were viable myocardium and 68 were non viable myocaridium.The sensitivity and specificity of CMR-LGE to determinate of viable myocardium were 92.0% and 91.1% respectively. The larger the non-viable myocardial area of the left ventricular wall, the worse the recovery of wall motion ability, and there was a negative correlation between them (r=0.416, P<0.05). The first-pass perfusion time in CMR-LEG region was significantly longer than that in normal myocardial region (4.85 (+) 1.51) s and (3.79 (+) 1.73) s, respectively. The difference was statistically significant (t = 5.191, P < 0.05). Conclusion: MRI can evaluate the myocardial activity of myocardial infarction, reflect the range of viable myocardium, and provide imaging basis for clinical treatment and prognosis.
