Objective: To analyze the potential categories and influencing factors of the compliance trajectory of orthokeratology lenses (OK lens) in myopic children and adolescents, so as to provide a basis for dynamic and accurate intervention of OK lens compliance in myopic children and adolescents. Methods: From January to June 2024, 310 myopic children and adolescents wearing OK lens were selected as research subjects from the Ophthalmology Medical Center of Cangzhou Central Hospital using a convenient sampling method. Data were collected at four time points: when the glasses were first fitted (T0), 2 weeks after fitting (T1), 1 month later (T2), 3 months later (T3), and 6 months later (T4). The data collection methods included general information questionnaires, compliance surveys for OK lens wearers, the Behavior Rating Inventory of Executive Function-Self-report Version (BRIEF-SR), family support scales, and a self-made questionnaire on myopia control attitudes. A growth mixed model was used to identify the trajectory categories of compliance with OK lens wearing among myopic children and adolescents, and multiple Logistic regression analysis was employed to examine the influencing factors. Results: The compliance with OK lens among myopic children and adolescents were roughly divided into four developmental trajectories: C1 exemplary adherent (58 cases, 18.71%), C2 gradual progressor (130 cases, 41.94%), C3 fluctuating (85 cases, 27.42%), and C4 stubborn low follower (37 cases, 11.94%). Multivariate Logistic regression analysis showed that, with C1 group as the reference, age (C3, OR = 0.74 ), parental education level (C4, OR =0.67), executive function (C2, OR =0.69; C4, OR =0.44), family support (C3, OR =0.75) and myopia control attitude (C2, OR =0.39) were all influencing factors for the compliance trajectory of OK lens; with C2 group as the reference, age (C3, OR = 0.55 ), parental education level (C3, OR =0.34; C4, OR =0.64), executive function (C3, OR =0.77), and family support (C4, OR =0.58) were all influencing factors for the compliance trajectory of OK lens; with C3 group as the reference, age (C4, OR = 0.68 ), and myopia control attitude (C4, OR =0.44) were both influencing factors for the compliance trajectory of OK lens ( P <0.05). Conclusions The compliance of wearing OK lens in children and adolescents with myopia can be roughly divided into four trajectories, and there is group heterogeneity. Dynamic and precise compliance intervention strategies should be given based on different trajectories and influencing factors.

Objective To investigate the effects of Aconite decoction （AD） on the viability and polarization of murine RAW264.7 macrophages induced by lipopolysaccharide （LPS） or interleukin-4 （IL-4）. Methods Cytotoxicity of AD was assessed by the CCK-8 assay. RAW264.7 cells were polarized toward M1 phenotype by LPS or M2 phenotype by IL-4, followed by treatment with varying concentrations of AD. Macrophage polarization was analyzed by flow cytometry. Quantitative PCR was performed to measure mRNA expression of polarization-associated markers （IL-6, iNOS, Arg1, and Ym1）. ELISA was used to quantify secreted cytokines （TNF-α and IL-10）in the supernatant. Results At non-toxic concentrations, IL-6 and iNOS mRNA levels in LPS-stimulated cells were significantly upregulated while Arg1 and Ym1 expression in IL-4-treated groups were downregulated by AD. Concurrently, TNF-α secretion in LPS-induced M1 polarization was enhanced but IL-10 production in IL-4-induced M2 polarization was suppressed by AD. Conclusion AD could promote macrophage proliferation and viability, augments LPS-driven M1 polarization, and inhibit IL-4-mediated M2 polarization, which provided experimental evidence for the potential application of AD in tumor immunotherapy.

OBJECTIVE: To assess the value of copy number variation sequencing (CNV-seq) for revealing the genetic etiology of fetuses with isolated ventricular septal defect (VSD). METHODS: From December 2017 to December 2020, 69 fetuses with isolated VSD were identified at the First Affiliated Hospital of Zhengzhou University. Meanwhile, 839 similar prenatal cases were selected from public databases including Wanfang data, Wanfang Medicine, and China National Knowledge Infrastructure (CNKI) by using keywords such as "Ventricular septal defect", "Copy number variation", and "Prenatal". A total of 908 fetuses with isolated VSD were analyzed. CNV-seq was carried out for 69 fetuses. RESULTS: Among the 908 fetuses, 33 (3.63%) were found to harbor pathogenic CNVs, which included 11 chromosomal aneuploidies (1.21%) and 22 pathogenic CNVs (2.42%). The pathogenic CNVs have involved 12 genetic syndromes, with those known to involve the heart development including 5 cases of 22q11.21 deletion syndrome, 2 cases of 4q terminal deletion syndrome, and 1 case of 9q subtelomere deletion syndrome. The outcome of pregnancies for 15 fetuses with pathogenic CNVs was known, of which 12 were terminated, and 3 had spontaneous closure of the ventricular septum after birth, but 1 of them had other abnormalities. CONCLUSION Fetuses with isolated VSD have a relatively high risk for chromosomal abnormalities, for which CNV-seq should be recommended.

Objective:To observe the effect and mechanism of Tanhuo Prescription on regulating the activation of M1 microglia and alleviating brain tissue injury in rats with cerebral ischemia.Methods:Male SD rats were divided into sham-operation group, model group, Tanhuo Prescription high-(3.68 g/kg), medium-(1.84 g/kg), low-dosage(0.92 g/kg) groups, and ginaton group (0.06 g/kg) using random number table method. Except for the sham-operation group, the other groups established cerebral ischemia rat models using the middle cerebral artery occlusion method. The balance beam walking test was used to evaluate the symptoms of neurological deficit. MRI-T2 mapping was used to measure the damage to brain tissue. LFB staining was used to observe the damage to nerve fibers. HE staining was used to observe the damage to nerve cell, and Iba-1 and CD16/Iba-1 immunofluorescence staining were used to observe the condition of microglial activation.Results:Compared with the model group, the scores of balance beam walking ability of rats in Tanhuo Prescription high-dose group and ginaton group at 24 h, 48 h and 72 h after ischemia were significantly improved ( P<0.05, P<0.01). The scores of balance beam walking ability of rats in Tanhuo Prescription low- and medium- dose groups at 72 h after ischemia were improved ( P<0.01). Compared with the model group, the T2 values of the cortex and striatum around the infarct of rats in Tanhuo Prescription high-dose group and ginaton group were significantly reduced ( P<0.05, P<0.01), and the T2 values of the striatum around the infarct of rats in Tanhuo Prescription low- and medium- dose groups were significantly reduced ( P<0.05). Compared with the model group, the LFB IOD of the cortex, striatum and outer capsule around the infarct decreased in the Tanhuo Prescription high-,low-dose group and ginaton group ( P<0.01). The LFB IOD of striatum around infarct decreased in medium- dose Tanhuo Prescription group ( P<0.01). Compared with the model group, the pathological injury degree of the striatum around the infarct of rats in Tanhuo Prescription low- ,medium-, and high-dose groups decreased, and the cell density decreased ( P<0.05, P<0.01). The density of the cortical and striatum cells around the infarct of rats in ginaton group increased ( P<0.01, P<0.05). Compared with the model group, the number of Iba-1 and CD16/Iba-1 positive cells in the cortex and striatum around the infarct decreased in Tanhuo Prescription medium-, high-dose and ginaton groups ( P<0.01). The number of CD16/Iba-1 positive cells in the cortex and striatum around the infarct of rats in Tanhuo Prescription low-dose group decreased ( P<0.01), and the number of Iba-1 positive cells in the striatum around the infarct of rats in Tanhuo Prescription low-dose group decreased ( P<0.01). Conclusion:Tanhuo Prescription can improve the symptoms of neurological deficits in rats with cerebral ischemia, reduce the neuropathological damage in the cerebral area around ischemic infarction, and inhibit the activation of M1 microglia.

Objective: To investigate the effects of interleukin ( IL) -10 on the proliferation of HaCaT cells and CaCl2 induced expression of differentiation markers and its possible molecular mechanisms． Methods: HaCaT cells were treated with various concentrations of IL-10 (0，3，10，30 ng / ml) for different time (0，24，48，72 h) ，cell proliferation was measured using MTS，and cell cycle was determined by flow cytometry．HaCaT cells were pretreated with IL-10 (final concentration 10 ng / ml) for 1 h，then incubated with or without CaCl2 (final concentration 1. 2 mmol / L) for 24，48，72 h ，Western blot was performed to detect the effect of IL-10 on the expression of HaCaT keratinocyte differentiation markers．After pretreatment of HaCaT cells with PD98059，an inhibitor of mitogen-activated kinase-ERK1 /2，and LY294002，an inhibitor of phosphatidylinositol kinase-serine / threonine kinase (PI3K-AKT) ，the total RNA and proteins were extracted separately，real time quantitative polymerase chain reaction (RT-qPCR) and Western blot were used to examine the influence of IL-10 on the expression of differentiation markers (Keratin1，Keratin5，Involucrin) . Results : MTS results revealed that IL-10 (30 ng / ml and lower doses) did not alter the proliferation of HaCaT cells in 72 h．Flow cytometry analysis demonstrated that IL-10 had no significant influence on cell cycle progression．The results of Western blot showed that IL-10 upregulated the expression of differentiation markers Involucrin，while there was no significant effect on Keratin1 and Keratin5 ．Mechanism research analysis demonstrated that IL-10 could activate ERK1 /2 and AKT ，increase their phosphorylation levels ; RT-qPCR and Western blot results showed that PD98059 and LY294002 partially blocked IL-10 induced Involucrin expression． Conclusion At a particular concentration range，IL-10 has little effect on HaCaT proliferation ，but it partially upregulates the expression of differentiation marker Involucrin via the MAPKs-ERK1 /2 and PI3K-AKT pathways.

Objective:To explore the effect of intelligent rehabilitation device on lower limb function rehabilitation in stroke patients with hemiplegia.Methods:Using convenience sampling, 186 stroke hemiplegic patients admitted to the Department of Neurology and Surgery of Brain Hospital, Cangzhou Central Hospital from July 2021 to July 2022 were selected as the study subject. The patients were divided into a control group, a strengthening group, and an intelligent rehabilitation group, with 62 patients in each group using the random number table. The control group received routine rehabilitation for 40 minutes per day, 5 days per week, for a total of 4 weeks. On the basis of the control group, the strengthening group received an additional 30 minutes of routine rehabilitation training every day. The intelligent rehabilitation group received an additional 30 minutes of intelligent rehabilitation device exercise per day on top of the control group. The Fugl-Meyer Assessment Lower Extremity (FMA-L), Berg Balance Scale (BBS) scores, and Functional Ambulation Category (FAC) grading of three groups of patients before and after intervention were compared.Results:Sixty patients in each group completed the study. The FMA-L and BBS scores of the three groups of patients after intervention were higher than those before intervention, and the FAC grading was better than that that before intervention, with statistical differences ( P<0.05). After intervention, the FAM-L and BBS scores of the intelligent rehabilitation group were higher than those of the control group and the strengthening group, and the FAC grading was better than that of the control group and the strengthening group, and the differences were statistically significant ( P<0.05) . Conclusions:The intelligent rehabilitation device can improve the lower limb function of stroke patients with hemiplegia, and is worthy of clinical promotion and practice.

OBJECTIVE: To explore the clinical features and genetic basis for a child with Bainbridge-Ropers syndrome (BRPS). METHODS: Clinical data of the child were retrospectively analyzed. Copy number variation sequencing (CNV-seq) and trio based whole exome sequencing (trio-WES) were carried out. Prenatal diagnosis was provided for a at risk fetus from the pedigree, and genotype phenotype correlation was summarized through a literature review. RESULTS: The proband, a 6-year-old boy, has presented with feeding difficulties, specific craniofacial features, global developmental delay and intellectual disability, which has not improved after rehabilitation treatment. CNV-seq analysis of the patient showed no obvious abnormalities. A de novo heterozygous truncating variation, c.1448dupT (p.T484Nfs*5), was identified in the ASXL3 gene by trio-WES, which was a previously reported pathogenic variant. So far 14 Chinese patients with BRPS and ASXL3 variants have been reported. All patients have shown specific craniofacial features and delayed motor and speech development, and harbored 12 loss of function ASXL3 variants, which were de novo in origin and have clustered in exons 11 and 12 of the ASXL3 gene. CONCLUSION The heterozygous frameshift c.1448dupT (p.T484Nfs*5) variant of the ASXL3 gene probably underlay the disorder in this patient. BRPS should be considered in infants with feeding difficulties, special craniofacial features, global developmental delay and hand anomalies, and WES can help to delineate the pathogenesis and establish the definite diagnosis.

Objective:To study the effect of Tanhuo Formula (THW) on the expression of Glial Fibrillary Acidic Protein (GFAP), Caspase-3 and angiogenesis.Methods:Rats were divided into sham group, model group, low-dose THW group, medium-dose THW group, high-dose THW group and Ginaton group according to random number table method. Except the sham group, rats in other groups were subjected to the middle cerebral artery occlusion via a suture method. After 2 hours,rats in the low, medium and high dose of THW groups were gavaged with 0.92, 1.84 and 3.68 g/kg of THW dry extract powder solution respectively, and the Ginaton group were gavaged with 60 mg/kg of Ginaton, once every 24 hours for 3 days. Rats in sham operation group and model group were given equal volume of normal saline by gavage. The limb symmetry score was used to evaluate limb dysfunctions. The immunofluorescence staining of GFAP and Caspase-3 were applied to assess astrocyte activation and neuronal apoptosis, respectively. The double-labeled immunofluorescence staining of platelet-endothelial cell adhesion molecule (CD31) and chondroitinsulphate peoteoglycan (NG2) were performed to detect angiogenesis.Results:Compared with the model group, rats in the high-dose of THW group showed increased limb symmetry score ( P<0.01 or P<0.05), increased number of Caspase-3 (cortex: 765.0±122.4 vs. 1 131.0±392.9; striatum: 895.9±389.8 vs. 1 401.9±453.1) ( P<0.01 or P<0.05) and CD31 +/NG2 + (cortex: 1 355.0±257.9 vs. 825.4±308.1; striatum: 1 290.9±400.9 vs. 675.2±259.7) ( P<0.01) positive cells in the periinfarct cortex and striatum, and attenuated the integrated optical density of GFAP in the perilesional cortex (4 210.00±1 226.38 vs. 7 935.78±2 001.98) ( P<0.01). Conclusions:THW could ameliorate the limb functional disorders, inhibit astroglia activation, down-regulate the expression of Caspase-3, and enhanced angiogenesis in MCAO rats.
