Nasal glial heterotopia(NGH),formerly known as nasal glioma,is a rare congenital developmental abnormality.A two-year-old female infant with intranasal NGH was admitted to Affiliated Hospital of Yangzhou University in 2023.The patient treated in the Department of Otorhinolaryngology Head and Neck Surgery in our hospital due to bilateral runny nose.Finding a nasal space occupying lesion in the left nasal cavity,she was hospitalized as"nasal space occupying lesion(left)".Consequently,she underwent surgical treatment after completing the relevant examinations.The postoperative pathological examination results showed it was glioma,and then she was diagnosed with intranasal type of nasal glial heterotopia finally.After half a year of postoperative follow-up,there was no recurrence and complications such as meningitis and cerebrospinal fluid rhinorrhea.The incidence of NGH is very low,and it is easy to miss diagnosis.For congenital nasal midline tumors in children,NGH should be considered when CT results suggest the tumor is not communicated with the skull,which has a good prognosis after surgical treatment.

This is the first reported case of a female with monkeypox infection in Kunming City,Yunnan Province.An epi-demiological investigation was conducted to provide a scientific basis for the prevention and control of monkeypox epidemics in China,especially for early detection in females in accordance with the"Monkeypox prevention and control program(2023 ver-sion)".Diagnosis was performed as described in the"Monkeypox Diagnosis and Treatment Guidelines(2022 version)".Speci-mens were collected for laboratory testing.The epidemiological investigation determined that the female patient had sexual in-tercourse with her newly married husband once before disease onset and the husband hid his history of male homosexual sex.The laboratory test results of the woman and her husband were positive for the nucleic acid of the monkeypox virus.Both had typical clinical symptoms,including rash.The epidemiological investigation,clinical symptoms,laboratory test results,and previous epidemic data of monkeypox in Yunnan province confirmed the woman as the first female infected with monkeypox in Yunnan Province and her husband was the presumed source of infection.

Objective To investigate the effect of chaperone-mediated autophagy(CMA)on the damage of mouse microglial BV2 cells induce by unconjugated bilirubin(UCB).Methods The BV2 cell experiments were divided into two parts.(1)For the CMA activation experiment:control group(treated with an equal volume of dimethyl sulfoxide),QX77 group(treated with 20 μmol/L QX77 for 24 hours),UCB group(treated with 40 μmol/L UCB for 24 hours),and UCB+QX77 group(treated with both 20 μmol/L QX77 and 40 μmol/L UCB for 24 hours).(2)For the cell transfection experiment:LAMP2A silencing control group(treated with an equal volume of dimethyl sulfoxide),LAMP2A silencing control+UCB group(treated with 40 μmol/L UCB for 24 hours),LAMP2A silencing group(treated with an equal volume of dimethyl sulfoxide),and LAMP2A silencing+UCB group(treated with 40 μmol/L UCB for 24 hours).The cell viability was assessed using the modified MTT method.The expression levels of p65,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),and cysteinyl aspartate specific proteinase-1(caspase-1)were detected by Western blot.The relative mRNA expression levels of the inflammatory cytokines interleukin(IL)-l β,IL-6,and tumor necrosis factor-α(TNF-α)were determined by real-time quantitative polymerase chain reaction.Levels of IL-6 and TNF-α in the cell culture supernatant were measured using ELISA.The co-localization of heat shock cognate protein 70 with p65 and NLRP3 was detected by immunofluorescence.Results Compared to the UCB group,the cell viability in the UCB+QX77 group increased,and the expression levels of inflammation-related proteins p65,NLRP3,and caspase-1,as well as the mRNA relative expression levels of IL-1β,IL-6,and TNF-α and levels of IL-6 and TNF-αdecreased(P＜0.05).Compared to the control group,there was co-localization of heat shock cognate protein 70 with p65 and NLRP3 in both the UCB and UCB+QX77 groups.After silencing the LAMP2A gene,compared to the LAMP2A silencing control+UCB group,the LAMP2A silencing+UCB group showed increased expression levels of inflammation-related proteins p65,NLRP3,and caspase-1,as well as increased mRNA relative expression levels of IL-1 β,IL-6,and TNF-α and levels of IL-6 and TNF-α(P＜0.05).Conclusions CMA is inhibited in UCB-induced BV2 cell damage,and activating CMA may reduce p65 and NLRP3 protein levels,suppress inflammatory responses,and counteract bilirubin neurotoxicity.[Chinese Journal of Contemporary Pediatrics,2024,26(4):385-393]

This study aimed to analyze the biological foundation and biomarkers of stable coronary heart disease(CHD) with phlegm and blood stasis(PBS) syndrome based on RNA-seq and network pharmacology. Peripheral blood nucleated cells from five CHD patients with PBS syndrome, five CHD patients with non-PBS syndrome, and five healthy adults were collected for RNA-seq. The specific targets of CHD with PBS syndrome were determined by differential gene expression analysis and Venn diagram analysis. The active ingredients of Danlou Tablets were screened out from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, and the "component-target" prediction was completed through PubChem and SwissTargetPrediction. The "drug-ingredient-target-signaling pathway" network of Danlou Tablets against CHD with PBS syndrome was optimized by Cytoscape software. After the target biomarkers were identified, 90 participants were enrolled for diagnostic tests, and 30 CHD patients with PBS syndrome were included in before-and-after experiment to determine the therapeutic effect of Danlou Tablets on those targets. As revealed by RNA-seq and Venn diagram analysis, 200 specific genes were identified for CHD with PBS syndrome. A total of 1 118 potential therapeutic targets of Danlou Tablets were predicted through network pharmacology. Through integrated analysis of the two gene sets, 13 key targets of Danlou Tablets in the treatment of CHD with PBS syndrome were screened out, including CSF1, AKR1C2, PDGFRB, ARG1, CNR2, ALOX15B, ALDH1A1, CTSL, PLA2G7, LAP3, AKR1C3, IGFBP3, and CA1. They were presumably the biomarkers of CHD with PBS syndrome. The ELISA test further showed that CSF1 was significantly up-regulated in the peripheral blood of CHD patients with PBS syndrome, and was significantly down-regulated after Danlou Tablets intervention. CSF1 may be a biomarker for CHD with PBS syndrome, and it is positively correlated with the severity of the disease. The diagnostic cut-off of CSF1 for CHD with PBS syndrome was 286 pg·mL~(-1).

OBJECTIVE: To observe the effects of electroacupuncture (EA) on NLRP3 inflammasome and its downstream protein gastermin D (GSDMD) in rats with primary dysmenorrhea (PDM), and to explore the potential mechanism of EA on the treatment of PDM. METHODS: Forty healthy female SD rats without pregnancy were randomly divided into a control group, a model group, an EA group and an ibuprofen group, 10 rats in each group. PDM model was prepared by injection of estradiol benzoate and oxytocin. Except the control group, the rats in each group were subcutaneously injected with estradiol benzoate for 10 days, and oxytocin was injected on the 11th day. The rats in the EA group were intervened with EA (dense wave, frequency of 50 Hz) at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) at the same time of modeling, once a day, 20 min each time, for 10 consecutive days. The rats in the ibuprofen group were treated with 0.8 mL of ibuprofen by gavage (concentration of ibuprofen solution was 1.25 mg/mL) for 10 consecutive days. After modeling, the writhing reaction was observed. After intervention, the HE staining method was used to observe the histological morphology of uterus and evaluate the pathological damage score of uterus; ELISA method was used to detect the serum levels of prostaglandin E2 (PGE2) and prostaglandin F2α (PGF2α); Western blot method was used to detect the protein expression of NLRP3, apoptosis related spot like protein (ASC), caspase-1, GSDMD, GSDMD-N and inflammatory factors (interleukin [IL]-1β, IL-18) in uterine tissue. RESULTS: In the model group, a large number of vacuolar degeneration and death of endometrial epithelial cells, spiral arterioles congestion in lamina propria and neutrophil infiltration were observed. In the EA group, there was a small amount of vacuolar degeneration and death of endometrial epithelial cells, a small amount of spiral arterioles congestion in the lamina propria, and a small amount of neutrophils infiltration. In the ibuprofen group, there was very small number of degeneration and death of endometrial epithelial cells, and no obvious arterial congestion was found in lamina propria, and neutrophil infiltration was occasionally seen. Compared with the control group, in the model group the number of writhing was increased (P<0.01), the writhing reaction score and serum level of PGF2α and PGF2α/PGE2 value were increased (P<0.01), the level of PGE2 was decreased (P<0.01). Compared with the model group, in the EA group and the ibuprofen group the number of writhing were decreased (P<0.05), the latency of writhing was prolonged (P<0.01), the writhing reaction scores and serum levels of PGF2α and PGF2α/PGE2 values were decreased (P<0.05, P<0.01), the levels of PGE2 were increased (P<0.01). Compared with the control group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was increased in the model group (P<0.01). Compared with the model group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was decreased in the EA group and the ibuprofen group (P<0.01, P<0.05). There was no significant difference between the EA group and the ibuprofen group in the above indexes (P>0.05). CONCLUSION EA could alleviate pain and uterine tissue injury in rats with PDM. The mechanism may be related to the inhibition of the activation of NLRP3 inflammasome in rat uterine tissues, thereby inhibiting pyroptosis and its inflammatory factors release.

ObjectiveTo explore the potential anti-tuberculosis mechanism of Kanglao granule through network pharmacology. MethodThe active components of Kanglao granule were retrieved from related databases and the potential targets of the components from SwissTargetPrediction. Targets of the tuberculosis were screened from GeneCards and National Center for Biotechnology Information （NCBI）， and the anti-tuberculosis targets of the prescription were further identified. STRING and Cytoscape 3.8.0 were employed to construct the Chinese medicinal-disease target-signaling pathway network and screen core targets. Then gene ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment were performed. Finally， AutoDock Vina was used for molecular docking between the active components of the prescription and key proteins and Western blotting for verifying the interaction between them. ResultA total of 29 important chemical components in the prescription were screened out， including β-sitosterol， sesamin， and kaempferol. A total of 28 key anti-tuberculosis targets were retrieved， such as protein kinase B1 （Akt1）， epidermal growth factor receptor （EGFR）， hypoxia inducible factor-1A （HIF-1A）， proto-oncogene tyrosine-protein kinase （SRC）， and matrix metalloproteinase-9 （MMP-9）. Bioinformatics analysis showed the 28 targets were involved in 41 GO terms such as oxygen metabolism， nucleic acid transcription， and metabolic enzyme pathway， and 28 key KEGG pathways， including Mycobacterium tuberculosis signaling pathway and phosphatidylinositol 3 kinase/protein kinase B pathway. Molecular docking results showed that Akt1 had the strongest binding affinity to sesamin. In vitro experiment indicated that sesamin inhibited the growth of M. tuberculosis by suppressing the phosphorylation of Akt1. ConclusionKanglao granule improved the sterilization level and immune response through multi-component， multi-target， and multi-pathway interactions， thereby achieving therapeutic effect on tuberculosis. Akt1 is one of the important targets involved in the treatment of tuberculosis.

Objective:To explore the effect and mechanism of Xiangshenwan on ulcerative colitis （UC） induced by dextran sulfate sodium （DSS） in mice based on the classic Toll-like receptor （TLR）/nuclear factor kappa B （NF-κB） signaling pathway. Method:The experimental mice were divided into a normal group， a model group， a Xiangshenwan group， and a mesalazine group. The mice， except for those in the normal group， received 3% DSS solution for 7 days to establish the acute UC model and were treated with Xiangshenwan （5 g·kg^-1） and mesalazine （300 mg·kg^-1） continuously from the 1st day to the 10th day of modeling. The body weight， disease activity index （DAI）， colon weight， intestinal weight index， colon length， colon weight per unit length， and pathological changes of mice were evaluated respectively. The protein expression of TLR5， myeloid differentiation factor 88 （MyD88）， interleukin-1 receptor-associated kinase 4 （IRAK4）， tumor necrosis factor receptor-associated factor 6 （TRAF6）， transforming growth factor β-activated kinase 1 （TAK1）， p38 mitogen-activated protein kinase （MAPK）， NF-κB， IRAK1， TAK1-binding protein 1 （TAB1）， TAB2， mitogen-activated protein kinase kinase 3 （MKK3）， MKK6 and cyclic adenosine monophosphate response element-binding protein （CREB） in colon tissues of mice was detected by Western blot. Result:Compared with the normal group， the model group showed decreased body weight of mice， increased DAI scores， elevated colon weight， intestinal weight index， and colon weight per unit length， shortened colon length， severe colonic mucosal injury， and up-regulated protein expression of TLR5， MyD88， IRAK4， TRAF6， TAK1， p38 MAPK， NF-κB， IRAK1， TAB1， TAB2， MKK3， MKK6， and CREB in colon tissues （P<0.05， P<0.01）. Compared with the model group， the Xiangshenwan group and the mesalazine group displayed increased body weight of mice， decreased DAI scores， declining colon weight， intestinal weight index， and colon weight per unit length， increased colon length， improved colonic mucosal injury， and down-regulated protein expression of TLR5， MyD88， IRAK4， TRAF6， TAK1， p38 MAPK， NF-κB， IRAK1， TAB1， TAB2， MKK3， MKK6， and CREB in colon tissues （P<0.05， P<0.01）. Conclusion:Xiangshenwan can effectively treat DSS-induced UC presumedly by the inhibition of TLR/NF-κB signaling pathway.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

Objective:To investigate the effect of virtual reality balance training on knee proprioception after anterior cruciate ligament reconstruction (ACLR). Methods:From January, 2016 to December, 2018, 72 patients after ACLR were randomly divided into control group (n = 36) and observation group (n = 36). On the basis of routine rehabilitation, they received routine balance training and balance training with virtual reality, respectively, for eight weeks. Before and after training, the center of pressure (COP) time stability, the COP speed (COPS) of closed eyes, the COPS of one leg, the knee joint reaction time, the center of pressure area (COPA) and the active joint angle recurrence deviation were measured. Results:After training, the COP time stability, the COPS of closed eyes, the COPS of one leg, knee joint reaction time, COPA and active joint angle recurrence deviation improved in both groups (|t|>5.611, P < 0.001); and the COP time stability, the COPS of closed eyes, the COPS of one leg, the knee joint reaction time and active joint angle recurrence deviation were better in the observation group than in the control group (|t| > 3.232, P < 0.01), however, no significant difference was found in COPA between two groups (t = 1.054, P = 0.296). Conclusion:Virtual reality balance training can improve the proprioception of knee joint after ACLR, which is better than routine balance training.
