Social media content analysis of public and private Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency facebook groups

Background@#As social media continue to grow as popular and convenient tools for acquiring and disseminating health information, the need to investigate its utilization by laypersons encountering common medical issues becomes increasingly essential. @*Objectives@#This study aimed to analyze the content posted in Facebook groups for Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency and how these engage the members of the group. @*Methods@#This study employed an inductive content analysis of user-posted content in both public and private Facebook groups catering specifically to G6PD deficiency. The G6PD Facebook groups with 10 or more posts within the past 12 months were selected for this study. Data were harvested from posts and comments using ExportComment. @*Results@#A total of 46 G6PD-related Facebook groups were identified. Of which, 19 were public and 27 were private groups, with an average membership of 5000-6000 accounts. After eligibility based on criteria and authorization for private groups, 3 public and 3 private groups were included, with the majority of these groups focused on sharing information. Five main themes of posted content were identified: diagnosis, management, beliefs, psychosocial factors, and medical requirements. “Diagnosis”-related posts referred to conversations about the causes and symptoms of G6PD, “management” referred to medication or diet, “beliefs” involved traditional or lay perceptions, “psychosocial factors” referred to posts that disclosed how psychosocial factors influenced G6PD deficiency practices, and “medical requirements” referred to documentation regarding the condition. The bulk of these posts used three strategies for communication: information-requesting, self-disclosure, and promotion of products/services. Information requests were the most common. @*Conclusion@#The results of the study showed opportunities and challenges in health education on G6PD, especially in evaluating the credibility and accuracy of the information given and received. Looking at the content and manner of communicating information noted, the newborn screening program may improve its advocacy and education campaign, and may develop targeted educational materials and effective dissemination strategies that could clarify, explain, or refute information and beliefs mostly shared on these platforms.

Long non-coding RNA C2dat1 involved in diabetic renal interstitial fibrosis by influencing CaMK2D/NF-κB signaling pathway / 中华微生物学和免疫学杂志

Objective:To study the changes in long non-coding RNA C2dat1 expression in kidney tissues of rats at different stages of diabetic kidney disease (DKD) and its relationship with renal interstitial fibrosis.Methods:Forty-eight male SD rats were randomly divided into two groups with 24 rats in each group: control group and DKD group. The rats in the control group were fed with ordinary diet, while those in the DKD group were fed with high-fat diet and drank water freely. After eight weeks of feeding, the rats were fasted for 12 h with free access to water. Then, the DKD group was given a one-time intrabitoneal injection of streptozotocin and the control group was given an equal dose of sodium citrate buffer. After 72 h, the random peripheral blood glucose concentration (≥ 16.7 mmol/L for three consecutive days) and urine sugar (positive) were tested to assess the establishment of the diabetes model. Urine, blood and kidney samples were collected at 3, 6, 9 and 12 weeks. The urinary protein excretion rate within 24 h, urinary creatinine and serum total cholesterol were measured by automatic biochemical apparatus. Pathological changes in kidney tissues were observed by HE staining. The expression of calcium/calmodulin-dependent protein kinase Ⅱ delta (CaMK2D), p65, p50, α-SMA and E-cardherin was detected by immunohistochemistry. Quantitative real-time PCR (qPCR) was used to detect the expression of lncRNA C2dat1 and CaMK2D. The relationship of lncRNA C2dat1 with α-SMA, E-cardherin and CaMK2D was analyzed by correlation analysis. In in vitro experiment, renal tubular epithelial cells HK-2 were induced by high glucose. The expression of lncRNA C2dat1 and CaMK2D in HK-2 cells was detected by qPCR after 24, 48 and 72 h of intervention. Results:The rats in the DKD group showed typical symptoms such as polydipsia, polyphagia, significant weight loss and increased blood glucose as compared with the rats in the control group. Results of the biochemical tests revealed that compared with the control group, the DKD group had increased 24 h excretion rate of urinary protein, decreased urinary creatinine and up-regulated total cholesterol. HE staining showed that the rats in the control group had intact glomeruli, normal basement membrane and no mesangial hyperplasia or inflammatory cell infiltration. However, enlarged glomeruli and evenly thickened basement membrane were observed in the DKD group. Immunohistochemistry indicated that the expression of CaMK2D, p50 and α-SMA was higher in the DKD group than in the control group, while the expression of E-cardherin was lower in the DKD group. qPCR results showed that the expression of lncRNA C2dat1 and CaMK2D at mRNA level was higher in the DKD group than in the control group. In in vitro experiment, the expression of lncRNA C2dat1 and CaMK2D at mRNA level was also higher in HK-2 cells induced by high glucose than in the control group. Correlation analysis indicated that lncRNA C2dat1 was positively correlated with α-SMA and CaMK2D, but negatively correlated with E-cardherin. Conclusions:During the progression of DKD, the high expression of lncRNA C2dat1 might promote diabetic renal interstitial fibrosis by regulating the expression of CaMK2D to activate the NF-κB signaling pathway.

Mechanism of Yishen Tonglong Decoction inhibiting TLR4/p38 MAPK/NF-κB signaling pathway against prostate cancer via upregulating miR-145-5p / 数字中医药（英文）

@#【Objective】 To investigate the mechanism of Yishen Tonglong Decoction (益肾通癃汤, YSTLD) inhibiting the toll-like receptor 4/p38 mitogen activated protein kinases/nuclear factor kappa-B (TLR4/p38 MAPK/NF-κB) signaling pathway against prostate cancer by up-regulating miR-145-5p. 【Methods】 miRNA microarray technology was used to detect the changes of miRNA expression profile in prostate cancer PC-3 cells treated with YSTLD, and miRNAs with marked differences in miRNA microarray results were screened and validated by real-time polymerase chain reaction (qRT-PCR). Lentiviral transfection of miR-145-5p into prostate cancer PC-3 cells, Cell Counting Kit-8 (CCK8) assay, and scratch assay were adopted to detect the effects of miR-145-5p on prostate cancer PC-3 cell proliferation and migration. qRT-PCR and Western blot were employed to detect the effects of miR-145-5p on TLR4/p38 MAPK/NF-κB signaling pathway and the expression levels of apoptosis-related genes caspase3, tumor necrosis factor-α (TNF-α), Bax, and Bcl-2. qRT-PCR and Western blot were used to detect the effects of serum containing YSTLD on miR-145-5p, TLR4/p38 MAPK/NF-κB signaling pathway, and the expression levels of apoptosis-related genes caspase3, TNF-α, Bax, and Bcl-2. 【Results】 The expression levels of 35 miRNAs in prostate cancer PC-3 cells treated with YSTLD were significantly different from those in the control group, with miR-145-5p being the most significantly different; qRT-PCR validation revealed that the miR-145-5p levels in prostate cancer PC-3 cells treated with YSTLD were significantly higher than those in the DMSO control group (P < 0.05). After lentiviral transfection of miR-145-5p into prostate cancer PC-3 cells, miR-145-5p was found to inhibit the proliferation and migration of prostate cancer PC-3 cells. Overexpression of miR-145-5p up-regulated expression levels of caspase3, TNF-α, and Bax mRNA, and down-regulated expression levels of p38 MAPK, p65 NF-κB, and Bcl-2 mRNA in prostate cancer PC-3 cells (P < 0.05), while up-regulated caspase3 protein expression levels in prostate cancer PC-3 cells and down-regulated expression levels of TLR4, p38 MAPK, and p65 NF-κB protein (P < 0.05). Serum containing YSTLD could up-regulate the expression levels of caspase3, TNF-α, and Bax mRNA, and down-regulate the mRNA expression levels of p38 MAPK, p65 NF-κB, Bcl-2, and TNF receptor-associated factor 1 (TRAF1) in prostate cancer PC-3 cells after intervening prostate cancer PC-3 cells (P < 0.05). Simultaneously, it up-regulated the expression levels of caspase3 protein and down-regulated the protein expression levels of TLR4, p38 MARK, p65 NF-κB, and TRAF1 in prostate cancer PC-3 cells (P < 0.05). 【Conclusion】 YSTLD can promote apoptosis of prostate cancer PC-3 cells by up-regulating the expression level of miR-145-5p and inhibiting TLR4/p38 MAPK/NF-κB signaling pathway, which may be an important mechanism of YSTLD against prostate cancer.

Mutation-associated transcripts reconstruct the prognostic features of oral tongue squamous cell carcinoma / 国际口腔科学杂志·英文版

Tongue squamous cell carcinoma is highly malignant and has a poor prognosis. In this study, we aimed to combine whole-genome sequencing, whole-genome methylation, and whole-transcriptome analyses to understand the molecular mechanisms of tongue squamous cell carcinoma better. Oral tongue squamous cell carcinoma and adjacent normal tissues from five patients with tongue squamous cell carcinoma were included as five paired samples. After multi-omics sequencing, differentially methylated intervals, methylated loop sites, methylated promoters, and transcripts were screened for variation in all paired samples. Correlations were analyzed to determine biological processes in tongue squamous cell carcinoma. We found five mutated methylation promoters that were significantly associated with mRNA and lncRNA expression levels. Functional annotation of these transcripts revealed their involvement in triggering the mitogen-activated protein kinase cascade, which is associated with cancer progression and the development of drug resistance during treatment. The prognostic signature models constructed based on WDR81 and HNRNPH1 and combined clinical phenotype-gene prognostic signature models showed high predictive efficacy and can be applied to predict patient prognostic risk in clinical settings. We identified biological processes in tongue squamous cell carcinoma that are initiated by mutations in the methylation promoter and are associated with the expression levels of specific mRNAs and lncRNAs. Collectively, changes in transcript levels affect the prognosis of tongue squamous cell carcinoma patients.

Meta-analysis denoted that ADHD group resulted in potentials of slightly lower MMN amplitude （WMD=-0.334， 95% CI： -1.426~0.758， P=0.549） and notably longer MMN latency （WMD=14.768， 95% CI： 4.660~24.876， P=0.004） compared to control group， and the Bgger's funnel plot did not reveal any publication bias. ConclusionCompared with healthy controls， ADHD children have longer MMN latency， suggesting that the auditory perception and attention level of ADHD children may be reduced.

Diagnostic value of nasal nitric oxide for children with primary ciliary dyskinesia / 中华儿科杂志

Objective: To evaluate the value of nasal nitric oxide (nNO) measurement as a diagnostic tool for Chinese patients with primary ciliary dyskinesia (PCD). Methods: This study is a retrospective study. The patients were recruited from those who were admitted to the respiratory Department of Respiratory Medicine, Children's Hospital of Fudan University from March 2018 to September 2022. Children with PCD were included as the PCD group, and children with situs inversus or ambiguus, cystic fibrosis (CF), bronchiectasis, chronic suppurative lung disease and asthma were included as the PCD symptom-similar group. Children who visited the Department of Child health Care and urology in the same hospital from December 2022 to January 2023 were selected as nNO normal control group. nNO was measured during plateau exhalation against resistance in three groups. Mann-Whitney U test was used to analyze the nNO data. The receiver operating characteristic of nNO value for the diagnosis of PCD was plotted and, the area under the curve and Youden index was calculated to find the best cut-off value. Results: nNO was measured in 40 patients with PCD group, 75 PCD symptom-similar group (including 23 cases of situs inversus or ambiguus, 8 cases of CF, 26 cases of bronchiectasis or chronic suppurative lung disease, 18 cases of asthma), and 55 nNO normal controls group. The age of the three groups was respectively 9.7 (6.7,13.4), 9.3 (7.0,13.0) and 9.9 (7.3,13.0) years old. nNO values were significantly lower in children with PCD than in PCD symptom-similar group and nNO normal controls (12 (9,19) vs. 182 (121,222), 209 (165,261) nl/min, U=143.00, 2.00, both P<0.001). In the PCD symptom-similar group, situs inversus or ambiguus, CF, bronchiectasis or chronic suppurative lung disease and asthma were significantly higher than children with PCD (185 (123,218), 97 (52, 132), 154 (31, 202), 266 (202,414) vs. 12 (9,19) nl/min,U=1.00, 9.00, 133.00, 0, all P<0.001). A cut-off value of 84 nl/min could provide the best sensitivity (0.98) and specificity (0.92) with an area under the curve of 0.97 (95%CI 0.95-1.00, P<0.001). Conclusions: nNO value can draw a distinction between patients with PCD and others. A cut-off value of 84 nl/min is recommended for children with PCD.

Jinyinqingre Oral Liquid alleviates LPS-induced acute lung injury by inhibiting the NF-κB/NLRP3/GSDMD pathway / 中国天然药物

Acute lung injury (ALI) is a prevalent and severe clinical condition characterized by inflammatory damage to the lung endothelial and epithelial barriers, resulting in high incidence and mortality rates. Currently, there is a lack of safe and effective drugs for the treatment of ALI. In a previous clinical study, we observed that Jinyinqingre oral liquid (JYQR), a Traditional Chinese Medicine formulation prepared by the Taihe Hospital, Affiliated Hospital of Hubei University of Medicine, exhibited notable efficacy in treating inflammation-related hepatitis and cholecystitis in clinical settings. However, the potential role of JYQR in ALI/acute respiratory distress syndrome (ARDS) and its anti-inflammatory mechanism remains unexplored. Thus, the present study aimed to investigate the therapeutic effects and underlying molecular mechanisms of JYQR in ALI using a mouse model of lipopolysaccharide (LPS)-induced ALI and an in vitro RAW264.7 cell model. JYQR yielded substantial improvements in LPS-induced histological alterations in lung tissues. Additionally, JYQR administration led to a noteworthy reduction in total protein levels within the BALF, a decrease in MPAP, and attenuation of pleural thickness. These findings collectively highlight the remarkable efficacy of JYQR in mitigating the deleterious effects of LPS-induced ALI. Mechanistic investigations revealed that JYQR pretreatment significantly inhibited NF-κB activation and downregulated the expressions of the downstream proteins, namely NLRP3 and GSDMD, as well as proinflammatory cytokine levels in mice and RAW2647 cells. Consequently, JYQR alleviated LPS-induced ALI by inhibiting the NF-κB/NLRP3/GSDMD pathway. JYQR exerts a protective effect against LPS-induced ALI in mice, and its mechanism of action involves the downregulation of the NF-κB/NLRP3/GSDMD inflammatory pathway.

Matrix metalloproteinase 14 and plasma kallikrein 1 may be potential biomarkers in the diagnosis and treatment of sepsis: a proteomics and bioinformatics analysis / 中华危重病急救医学

Objective:To analyze protein profiles in septic patients, and to find potential new targets for the diagnosis and treatment of sepsis.Methods:A cross sectional observational study was conducted. From January to December 2019, 12 septic patients and 9 healthy volunteers were recruited in the emergency intensive care unit (EICU) of the emergency department of the Affiliated Hospital of Southwest Medical University. The peripheral blood of the two groups was collected for protein mass spectrometry analysis, and the data-independent acquisition technology was used to obtain the expression data of each protein. The obtained data was imported into the online network tool Integrated Differential Expression and Pathway analysis (IDEP2), the data underwent ID converted and were homogenized to verify their comparability, and then principal component analysis was used to eliminate outlier data. Then data with P < 0.05, log 2fold change (FC) > 1 or log 2FC < -1 were considered to have a statistically significant difference, and the differential proteins were screened out. On the DAVID website, the screened differential proteins would be analyzed by gene ontology (GO), and the biological process, cellular components, and molecular function of the proteins would be analyzed. Protein enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed. Protein-protein interaction (PPI) analysis was performed through the Search Tool for the Retrieval of Interacting Genes Database (STRING) website to find closely related proteins. Results:The data in this study were shown to be comparable after normalization. A total of 125 differential proteins were screened, of which 99 were up-regulated and 26 were down-regulated. GO enrichment analysis discovered that these proteins were mainly extracellular, with cellular regulatory functions and catalytic functions involved in biological regulation, metabolic process and immune process. KEGG pathway analysis suggested that these proteins were involved in amino acid, carbohydrate metabolism and immune-related pathways. PPI analysis showed that key proteins included matrix metalloproteinase 14 (MMP14), fibulin 1 (FBLN1), plasma kallikrein 1 (KLKB1), etc., and finally screened out MMP14 and KLKB1, which were closely related to inflammation and immunity. Both might be potential new targets for early diagnosis and treatment of sepsis.Conclusion:MMP14 and KLKB1 may be potential biomarkers for the diagnosis, treatment and prognosis of sepsis.

The median age was 37 (8, 86) months and the median body weight was 15 (7, 20) kg.The average pediatric critical illness score at admission was 84.2±7.7, PaO 2/FiO 2 was (245.5±99.8)mmHg.The primary diseases leading to PMV were as follows: there were 14 cases of severe pneumonia, eight cases of severe encephalitis, five cases of bronchopulmonary dysplasia, three cases of upper airway obstruction/craniofacial deformity, three cases of myasthenia, three cases of brain stem tumor, three cases of mitochondrial encephalomyopathy, two cases of spinal muscular atrophy, two cases of Prader-Willi syndrome, one case of dermatomyositis, one case of severe brain injury, and one case of central hypoventilation.The causes of unable to withdraw ventilator were respiratory dysfunction in 24 cases, brain dysfunction in 16 cases, and diaphragm dysfunction in six cases.Compared with neuromuscular diseases, children with PMV caused by respiratory diseases had lower month age, higher preterm birth rate, lower PaO 2/FiO 2 ratio, higher parameters for ventilator treatment, and the differences were statistically significant ( P<0.05). Children with PMV caused by neuromuscular diseases had lower Glasgow coma score and higher coma rate, and the differences were statistically significant ( P<0.05). A total of nine (19.6%) cases underwent tracheotomy.A total of 23 (50.0%) cases were successfully extubated from ventilator, six (13.0%) cases were dependent on invasive ventilator, and six (13.0%) cases were breathing with tracheotomy tube.The median mechanical ventilation time was 33 (28, 40) days, the median PICU hospital stay was 42 (34, 56) days, and the median hospital stay was 51 (41, 65) days.A total of 27 (58.7%) cases were improved and discharged, four (8.7%) cases were transferred to rehabilitation hospital, four (8.7%) cases were transferred to local hospital, and 11 (23.9%) cases died in hospital or at home after giving up. Conclusion:The main causes of PMV in PICU children are respiratory dysfunction, brain dysfunction and diaphragm dysfunction.50.0% of the children with PMV could be discharged from the ventilator, and 23.9% died or died after giving up.

Summary of best evidence for management of labor course induced by oxytocin drip in term pregnancy / 中国实用护理杂志

Objective:To search, evaluate and summarize the best evidences related to induction of labor by oxytocin infusion in pregnant women with full-term pregnancy, and to provide reference for clinical practice in order to reduce the complications during labor, such as the proportion of instrument delivery, prolonged labor duration, uterine rupture, postpartum hemorrhage, etc. Standardize the management process of induction of labor with oxytocin, improve the satisfaction of pregnant women to participate in the decision of induction of labor, and improve the outcome of the newborn.Methods:Take the evidence-based nursing method, in view of the full-term pregnancy pregnant women oxytocin drip induced labor evidence-based labor management problems, nearly 10 years related literature retrieval from January 1st 2011 to April 9th, 2021, the Australian JBI evidence-based health care center of literature quality evaluation criteria and evidence classification system, all kinds of research evaluation and classification of retrieval.Results:Early detection to 340 articles, and eventually into 9 articles, including 1 clinical decision, 6 guides, 2 pieces of system evaluation. Totally 45 pieces evidences related to induction of labor by oxytocin infusion in pregnant women with full-term pregnancy were sumarized, including induced labor time, oxytocin side effects, induced labor before evaluation, induced labor of guardianship, infusion solution, such as health education, and other seven aspects.Conclusions:The present study summarized 45 pieces of best evidence on the management of labor induced by oxytocin infusion during term pregnancy, which provided some evidence-based basis for midwives, obstetric nurses and managers. Through the application of the best evidence, it is beneficial to improve the outcome of pregnant women in the neonatal perinatal period, standardize the process of inducing labor with oxytocin, and improve the quality of obstetric care.

Progress on T cell subsets and pathogenesis of asthma / 国际儿科学杂志

Asthma is a common chronic airway inflammatory disease, which is characterized by airway stenosis, airway wall thickening and increased mucus secretion followed by reversible airflow restriction.At present, asthma is considered to be a complex and heterogeneous disease, and its pathogenesis remains elusive.There are diverse immune cells involved in the formation of asthma, including T lymphocytes, eosinophils, neutrophils, etc.Due to the continuous renewal of classification and function of T lymphocytes subsets, their role in asthma has attracted more attention.Here, this review aims to summarize the immunological characteristics and roles of different T cell subsets in asthma, and highlight the new findings of T cell subsets in the pathogenesis of severe asthma, leading to provide inspiration and help for the study of the immunology pathogenesis, clinical diagnosis, treatment and prognosis in asthma.

Investigation on the radiation of 131I in treatment site of a grade A tertiary hospital / 中国辐射卫生

Objective To detect the radiation of 131I in treatment site of a grade A tertiary hospital. Methods A total of 25 patients with thyroid cancer were administrated 131I at a total dose of 82880 MBq. After administration, the ambient dose equivalent rate of the ward was detected with X- and γ-ray detectors. After patient discharge, surface contamination of the ward was detected with α/β surface contamination meter. During patient hospitalization and on the day of discharge, air samples were collected from 131I treatment site and office area. The air samples were measured using a HPGe γ-ray spectrometer and the concentration of 131I in air was calculated. Results The ambient dose equivalent rate in the ward ranged from 0.15 to 0.46 μSv/h. Before ward cleaning, surface contamination ranged from 0.53 to 40.1 Bq/cm2 and the highest value was recorded on the toilet. Within 4 h after administration, the concentrations of 131I in air in treatment site and the corridor of the office area were 1.74 Bq/m3 and 0.66 Bq/m3, respectively. The ventilation air flow rate in the treatment site was 0.50 m/s. Ventilation decreased the concentration of 131I in air by 29.7%, 79.7%, and 53.3% compared with the previous day during hospitalization and on the day of discharge. Conclusion The radiation of external exposure of 131I in the treatment site is low and the shielding is effective. Before ward cleaning, the surface contamination is lower than the required limits except for the toilet. Ventilation is the primary way to reduce the concentration of 131I in air.
