Congenital heart disease (CHD) is a congenital malformation resulting from abnormal embryonic development of the heart and great vessels, accounting for approximately 25% of all congenital malformations. Children with CHD are often complicated by short stature. Although surgical treatment can improve their growth and development to a certain extent, some children still experience growth retardation after surgery. Recombinant human growth hormone (rhGH) is the main drug for treating short stature, but its efficacy and safety in the treatment of patients with concomitant CHD warrant further investigation. This article reports six cases of children with CHD and short stature who were treated with rhGH. Through a literature review, we summarize and discuss the therapeutic efficacy, follow-up experiences, and adverse reactions of rhGH treatment, aiming to provide references for clinicians in applying rhGH to treat patients with CHD and short stature.

Objective To explore the role of TMAO from gut microbiota in non-alcoholic fatty liver disease(NAFLD),we detected the serum level of TMAO and its precursor metabolites in NAFLD,as well as the expression level of Eubacterium rectum,Bacteroidetes multiforme,Lactobacillus and bifidobacterium in the intestinal flora.Methods We collected 118 subjects and divided into NAFLD group(86 cases)and healthy control group(32 cases)randomly.We also detected the serum level of TMAO and its precursor metabolites in subjects by high performance liquid chromatography tandem mass spectrometry detection(LC-MS),and the expression of target bacterial DNA was detected by qRT-PCR.Results Serum TMAO,TMA and choline levels were significantly increased in NAFLD(P<0.05),and liver fat content was positively correlated with TMAO(P<0.05).The expression level of Lactobacillus and Eubacterium rectum in NAFLD group were increased(P<0.05);the expression level of Bifidobacterium and Bacteroides multiform were decreased(P<0.05).The serum TMAO level was positively correlated with Eubacterium rectum(r=0.280,P<0.05),and negatively correlated with Bifidobacterium(r=-0.332,P<0.05).Conclusion The level of TMAO in serum shows a positive correlation with NAFLD.The structure of intestinal flora in individuals with NAFLD is altered and linked to TMAO.This suggests that the intestinal flora may have a significant impact on the development of NAFLD through TMAO.

Objective:To clarify the potential correlation between biological changes of meninges in periodontitis mice and cognitive impairment by analyzing the biological changes of meninges in periodontitis mice using single-cell RNA sequencing.Methods:Thirty C57BL/6 mice were divided into two groups by using random number table method (15 mice in each group). Mice in the control group were locally administered 2% carboxyl methyl cellulose (CMC) without Porphyromonas gingivalis (Pg) on both buccal sides. A mixture of Pg W83 and 2% CMC was applied on both buccal sides in the experimental group mice three times a week, lasting for 16 weeks in total. The absorption of alveolar bone, locomotor activity and cognitive function, the activation of microglia and astrocytes in the cortex were observed and assessed. The mRNA expression levels of Occludin in meninges and brain were detected in two groups. Single-cell RNA sequencing data of meninges were processed by uniform manifold approximation and projection (UMAP). Differential genes expressions of endothelial cells were processed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. In addition, real-time fluorescence quantitative PCR (RT-qPCR) was used to verify the expressions of transcription activating factor 3 (Atf3) and apolpoprotein L domain-containing 1 (Apold 1). Results:Methylene blue staining found the distances of buccal and palatal cement-enamel junction-alveolar bone crest in experimental mice [(185.60±17.60), (206.90±13.37) μm] increased significantly compared with the control group [(135.33±9.57), (163.05±14.98) μm] ( t=5.02, P=0.002; t=4.37, P=0.005). Open field experiment showed the total distance and average speed of mice in the experimental group [(971.88±164.57) cm, (3.25±0.55) cm/s] were not statistically significant compared with the control group [(914.24±278.81) cm, (3.05±0.93) cm/s] ( t=0.65, P=0.525; t=0.65, P=0.520). The recognition index of the experimental group [(48.02±16.92) %] was lower than the control group [(66.27±17.90) %] ( t=2.40, P=0.027) by novel object recognition tests. Compared with the control group [(63.56±11.88) %], the alternation of experimental group [(50.99±14.17) %] was significantly decreased in Y maze tests ( t=2.33, P=0.030). Immunohistochemistry results showed microglia and astrocytes were activated in the cortex of experimental mice. Compared with the control group (1.02±0.25, 1.04±0.31), the relative mRNA expressions of Occludin decreased significantly in the meninges and brain of periodontitis mice, respectively (0.61±0.10, 0.64±0.20) ( t=3.47, P=0.010; t=2.66, P=0.024). By single-cell RNA sequencing, meninges cells were divided into 11 types, such as endothelial cells, fibroblasts, immune cells and so on. Endothelial cells were the main cell types in meninges [the control group: 26.47% (1 589/6 004), the experimental group: 26.26% (807/3 073)]. Compared with the control group [5.56% (334/6 004)], the percentage of granulocytes increased in the periodontitis mice [11.65% (358/3 073)]. Using clustering analysis to further focus on endothelial cells, GO enrichment analysis revealed differential genes were mainly related to angiogenesis, cell adhesion, apoptosis and so on. KEGG enrichment analysis revealed that differential genes were related to signaling pathways of interleukin-17, relaxin and so on. The relative mRNA expressions of Atf3 and Apold1 in meninges of periodontitis mice (0.42±0.24, 0.54±0.27) were significantly lower than the control group (1.03±0.26, 1.02±0.23) ( t=3.88, P=0.005; t=3.02, P=0.017). Conclusions:The mice chronically infected with Pg W83 occurred memory impairment, neuroinflammation and changes of barrier function. In the meninges of periodontitis mice, there were infiltration of immune cells and down-regulation expressions of Atf3 and Apold1 by single-cell RNA sequencing. Meningeal immunity and changes of barrier function may play an important role in the cognitive impairment caused by periodontitis.

Objective To explore the role of secreted frizzled-related protein 3 (sFRP3), a regulator of the Wnt signaling pathway, in the activation and proliferation of murine cardiac fibroblasts (CFs).Methods Neonatal mice aged 1-3 days were obtained for surgical procedures to collect heart tissues.After digestion, CFs were isola-ted and cultured.Transforming growth factor-beta 1 (TGF-β1) stimulation was used to induce activation and prolif-eration in CFs after they adhered to the culture dish.Once the model was confirmed, experimental and control groups were transfected with sFRP3 overexpression plasmids and empty plasmids for 24-48 hours.Expression lev-els of sFRP3, Periostin (POSTN), Type Ⅰ collagen (Collagen Ⅰ), and proliferating cell nuclear antigen (PC-NA) were assessed at the molecular level using Western blot and qRT-PCR.Changes in cell proliferation capacity were examined using MTT, CCK-8, and EdU staining methods.Results In the TGF-β1-induced activation and proliferation model of CFs, compared to the control group, the model group exhibited decreased expression of sFRP3 protein and mRNA, while the expression of activation and proliferation-related proteins PCNA, POSTN, and Collagen Ⅰ was upregulated.Furthermore, in CFs overexpressing sFRP3 through plasmid transfection, the protein and mRNA expression of PCNA, POSTN, and Collagen Ⅰ decreased compared to the empty vector group.MTT, CCK-8 , and EdU experiments indicated a significant decrease in the proliferative activity of CFs in the sFRP3 over-expression group compared to the empty vector group.Conclusion Overexpression of sFRP3 markedly inhibits the activation and proliferation of CFs, suggesting that sFRP3 may be a key gene involved in the regulation of CF acti-vation and proliferation.

Background and purpose:Long noncoding RNA(lncRNA)can regulate gene transcription,mRNA shear,stabilization and translation,and it is an important regulatory factor in a variety of biological processes.This study aimed to investigate the expression and clinical features of lncRNA FLJ30679 in oral squamous cell carcinoma(OSCC)and its effect on the malignant biological behavior of OSCC.Methods:The expression of FLJ30679 in head and neck squamous cell carcinoma(HNSCC)tissues and normal tissues was analyzed by the UCSC Xena database for expression and prognosis.The expression of FLJ30679 in OSCC cell lines was detected by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR).The subcellular localization of FLJ30679 in OSCC cells was detected by RNA nuclear-cytoplasmic fractionation assays.FLJ30679 Smart Silencer was used to establish the FLJ30679 knockdown group(SS-FLJ30679),and overexpression plasmid of FLJ30679 was used to establish FLJ30679 overexpression group(FLJ30679).The effects of altered FLJ30679 expression on the proliferative and migration capacity of OSCC cells were examined by cell counting kit-8(CCK-8)and transwell migration assays.RTFQ-PCR and Western blot were used to determine the effect of altered FLJ30679 expression on the expression of epithelial-mesenchymal transition(EMT)-related genes in OSCC cells.The effects of altered FLJ30679 expression on the phosphoinositide 3-kinase(PI3K)/protein kinase(AKT)pathway were detected by Western blot.Results:Online query of database showed that FLJ30679 expression was higher in HNSCC tissues compared to normal tissues(P＜0.01).HNSCC patients with higher FLJ30679 expression had lower overall survival(P＜0.01).The RTFQ-PCR results showed that FLJ30679 was expressed at a higher level in six OSCC cell lines compared with normal cells,and was predominantly localized in the nucleus.The ability of OSCC cells in the SS-FLJ30679 group to proliferate and migrate was significantly lower compared with the SS-NC group(P＜0.01).OSCC cells in the FLJ30679 overexpression group had significantly higher proliferative and migratory capacities than those in the vector group(P＜0.001).RTFQ-PCR and Western blot results showed that FLJ30679 knockdown resulted in upregulation of mRNA and protein expression levels of E-cadherin(P＜0.01)and downregulation of mRNA and protein expression levels of N-cadherin and vimentin(P＜0.01).FLJ30679 overexpression resulted in downregulation of protein expression levels of E-cadherin(P＜0.01)and upregulation of mRNA and protein expression levels of N-cadherin and vimentin(P＜0.05).Western blot results showed that knockdown of FLJ30679 resulted in decreased protein expression levels of phosphorylated-PI3K(p-PI3K)and phosphorylated-AKT(p-AKT)(P＜0.001),and overexpression of FLJ30679 resulted in increased protein expression levels of p-PI3K and p-AKT(P＜0.01).Conclusion:The expression of FLJ30679 was increased in OSCC tissues and cells.It promoted the proliferation and migration ability of OSCC cells,which may be caused by FLJ30679 promoting EMT via PI3K/AKT pathway.

Objective To explore the correlation between contrast sensitivity and binocular visual function in indi-viduals with high myopia,aiming to understand how binocular visual function impacts contrast sensitivity in this popula-tion.Methods In this cross-sectional study,a total of 33 patients(66 eyes)with high myopia attending the Optometric Center of Tianjin Eye Hospital from March to December 2020 were included.They were measured for oculomotor parame-ters as well as binocular contrast sensitivity in photopic and scotopic conditions.According to the type of functional indica-tors to which the oculomotor parameters belong,they were divided into two groups:accommodation and vergence.The oculomotor parameters of accommodation include accommodative amplitude(AMP),monocular accommodative facility(MAF)and binocular accommodative facility(BAF);the oculomotor parameters of vergence include distance lateral pho-ria(DLP),near lateral phoria(NLP),positive fusional vergence(PFV),negative fusional vergence(NFV),and vergence facility(VF),among them,PFV includes the near and distance PFV breaking points and recovery points,and NFV includes the near and distance NFV breaking points and recovery points.Pearson bivariate correlation analysis was used to analyze the bivariate correlations between binocular contrast sensitivity and the oculomotor parameters of accommodation and ver-gence.In addition,canonical correlation analysis was used to analyze the associations between binocular contrast sensitivi-ty and accommodation and vergence indicators in patients with high myopia.Results The spherical equivalent refraction of the participants was(-9.51±2.71)D in the left eye and(-10.00±2.88)D in the right eye.The bivariate correlation analysis showed that among the oculomotor parameters of accommodation,the AMP of the left eye was negatively correla-ted with the contrast sensitivity at 18 c·d-1 under scotopic conditions(r=-0.406,P=0.019);among the oculomotor pa-rameters of vergence,the near PFV breaking point was positively correlated with the contrast sensitivity at 1.5 c·d-1(r=0.458)and3.0 c·d-1(r=0.441)under scotopic conditions(both P＜0.05),the near PFV recovery point was positively correlated with the contrast sensitivity at 3.0 c·d-1(r=0.351)and 6.0 c·d-1(r=0.396)under photopic conditions(both P＜0.05)and positively correlated with contrast sensitivity at 1.5 c·d-1(r=0.449),3.0 c·d-1(r=0.537)and 12.0 c·d-1(r=0.375)under scotopic conditions(all P＜0.05),and VF was positively correlated with contrast sensitivity at 1.5 c·d-1(r=0.358)under photopic conditions and 3.0 c·d-1(r=0.458)under scotopic conditions(both P＜0.05).Except for the above indicators,other oculomotor parameters of accommodation and vergence were not correlated with contrast sensitivity(all P＞0.05).Canonical correlation analysis showed that only the oculomotor parameters of vergence were correlated with the first pair of canonical correlation coefficients of contrast sensitivity under scotopic conditions(P=0.008)and the canonical correlation coefficient was 0.912.The oculomotor parameters of convergence U1 were mainly de-termined by NLP,near NFV recovery point,near PFV breaking point,and near PFV recovery point.Contrast sensitivity V,under scotopic conditions was mainly determined by contrast sensitivity at 1.5 c·d-1 and 6.0 c·d-1under scotopic condi-tions.The typical structural analysis showed that there was a strong positive correlation of U1 with near PFV breaking point and contrast sensitivity at 1.5 c·d-1 under scotopic conditions;there was a strong positive correlation of V1 with near PFV breaking point and contrast sensitivity at 1.5 c·d-1 under scotopic conditions.Conclusion There is an association be-tween vergence and contrast sensitivity under scotopic conditions among high myopia patients.Improving binocular visual function may enhance contrast sensitivity and overall visual quality in high myopia patients.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.

Objective To analyze the influencing factors of pancreatic fat deposition in patients with type 2 diabetes mellitus(T2DM),and to explore the relationship between pancreatic fat deposition and islet function.Methods A survey on diabetes prevalence was conducted among 548 residents in the Nicheng community of Pudong New Area from October 2015 to December 2016,including 301 patients with T2DM and 247 subjects with normal glucose tolerance(NGT).General information of the subjects were recorded,blood biochemical and insulin indexes were measured,body composition was measured by dual-energy X-ray absorptiometry,and insulin resistance index(HOMA-IR)and islet cell sensitivity index(HOMA-β)were calculated.Fatty liver and pancreatic fat deposition were detected by ultrasound.Both the T2DM group and NGT group were further divided into two subgroups according to the pancreatic fat deposition.Differences in general demographic information,biochemical and body fat indices among the groups were compared.Multivariate logistic regression was used to analyze the influencing factors of pancreatic fat deposition.Results In the NGT group,the subgroup with pancreatic fat deposition showed higher levels of age,waist circumference,waist-to-hip ratio(WHR),body mass index(BMI),fasting insulin levels(FINS),2-hour postprandial insulin levels(2 h INS),triglycerides(TG),uric acid(UA),alanine aminotransferase(ALT),fatty liver prevalence,abdominal fat percentage,and abdomen-to-hip ratio(AHR),compared with the subgroup without pancreatic fat deposition.High-density lipoprotein cholesterol(HDL-C)and limb fat percentage were lower in the subgroup with pancreatic fat deposition.In the T2DM group,the subgroup with pancreatic fat deposition showed higher levels of waist circumference,BMI,FINS,2 h INS,TG,UA,ALT,aspartate aminotransferase(AST),fatty liver prevalence,and abdominal fat percentage,compared with the subgroup without pancreatic fat deposition,with statistically significant differences(P<0.05).The HOMA-IR and HOMA-β in both NGT and T2DM groups with pancreatic fat deposition were significantly higher than those in the groups without pancreatic fat deposition.The prevalence of insulin resistance also significantly increased,with statistically significant differences(P<0.05).The results of multivariate logistic regression analysis showed that HDL-C,HOMA-β,abdominal fat percentage,age and fatty liver were the influencing factors for pancreatic fat deposition in NGT.Conclusion Elderly individuals with abdominal obesity and fatty liver are more prone to developing pancreatic fat deposition,which can affect islet function and aggravate the insulin resistance.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
