ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

ABSTRACT

Objective To investigate the expression and the potential roles of long non-coding RNA(lncRNA)cancer susceptibility candidate 2(CASC2)and imprinted gene H19 in extrahepatic cholangiocarcinoma(ECC). Methods Four samples from patients with ECC were collected for high-throughput sequencing which was conducted to reveal the transcriptomic profiles of lncRNA CASC2 and H19.Bioinformatics tools were employed to predict the potential roles of the two genes.Another 22 ECC tissue samples and the cholangiocarcinoma cell lines(RBE,QBC939,HuH-28,and HuCCT1)with different degrees of differentiation were selected for validation.The para-carcinoma tissue and normal human intrahepatic biliary epithelial cell(HIBEC)were used as the control groups.The expression levels of lncRNA CASC2 and H19 in carcinoma tissue,para-carcinoma tissue,and cell lines were determined by real-time quantitative polymerase chain reaction(qRT-PCR).The correlation analysis was carried out for the clinical indicators of patients with the expression levels of the target genes. Results The two target genes showed significantly different expression between carcinoma tissue and para-carcinoma tissue(all P<0.05).Specifically,CASC2 had higher expression level in the carcinoma tissue than in the para-carcinoma tissue(t=1.262,P=0.025),whereas the expression of H19 showed an opposite trend(t=1.285,P=0.005).The expression levels of CASC2 in QBC939(t=8.114,P=0.015)and HuH-28(t=9.202,P=0.012)cells were significantly higher than that in the control group.The expression levels of H19 were significantly lower in RBE(t=-10.244,P<0.001),QBC939(t=-10.476,P<0.001),HuH-28(t=-19.798,P<0.001),and HuCCT1(t=-16.193,P=0.004)cells than in the control group.Bioinformatics analysis showed that CASC2 was mainly involved in the metabolic process and H19 in the development of multicellular organisms.Both CASC2 and H19 were related to catalytic activity.The expression level of lncRNA CASC2 was correlated with pathological differentiation(χ 2=6.222,P=0.022)and lymph node metastasis(χ2=5.455,P=0.020),and that of lncRNA H19 with pathological differentiation(χ2=1.174,P=0.029)and tumor size(χ2=-0.507,P=0.037). Conclusions In the case of ECC,lncRNA CASC2 and H19 have transcription disorders.lncRNA CASC2 is generally up-regulated in the carcinoma tissue,while H19 is down-regulated.Both genes have the potential to become new molecular markers for ECC.

ABSTRACT

Objective To analyze the drug-drug interaction (DDI) between intravenous voriconazole (VRZ) and intravenous cyclosporine (CsA) in patients after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and provide an individualized and accurate clinical drug delivery. Methods In a self-contrast study, Allo-HSCT patients from January 2019 to December 2019 were enrolled according to the inclusion and exclusion criteria. These patients were treated with CsA and VRZ successively and the blood concentration of CsA and VRZ before and after 5-7 days of VRZ administration were determined with LC-MS/MS. The correlation between the concentration of VRZ and concentration/dose (C/D) ratio of CsA was analyzed with SPSS20.0. Results A total of 15 patients with ALLo-HSCT were enrolled. Wilcoxon sign rank sum test was used to compare the change of median C/D of CsA before and after VRZ administration, which had shown significant difference (P<0.001). Spearman correlation analysis was conducted on the increase of C/D ratio between VRZ and CsA, which had no significant correlation between them (ρ=−0.273, P=0.32). Conclusions There was obvious drug-drug interaction (DDI) between CsA and VRZ. VRZ increased CsA blood concentration significantly, but there was no significant correlation between VRZ blood concentration and the degree of concentration increase, which might be related to individual difference.

ABSTRACT

BACKGROUND@#Although osteopontin (OPN) is expressed in the liver and pigment gallstones of patients with hepatolithiasis, its role in pigment gallstone formation remains unclear. This study aimed to explore the function of OPN in pigment gallstone formation.@*METHODS@#Rats were fed a chow diet (CD) or lithogenic diet (LD) for 10 consecutive weeks; blocking tests were then performed using an OPN antibody (OPN-Ab). Incidence of gallstones and levels of several bile components, OPN, tumor necrosis factor alpha (TNF-α), and cholesterol 7 alpha-hydroxylase (CYP7A1) were analyzed. To determine TNF-α expression in hepatic macrophages and both CYP7A1 and bile acid (BA) expression in liver cells, recombinant rat OPN and recombinant rat TNF-α were used to treat rat hepatic macrophages and rat liver cells, respectively. Chi-square or Fisher exact tests were used to analyze qualitative data, Student t-test or one-way analysis of variance were used to analyze qualitative data.@*RESULTS@#Incidence of gallstones was higher in LD-fed rats than in CD-fed rats (80% vs. 10%, P < 0.05). BA content significantly decreased in bile (t = -36.08, P < 0.01) and liver tissue (t = -16.16, P < 0.01) of LD-fed rats. Both hepatic OPN protein expression (t = 9.78, P < 0.01) and TNF-α level (t = 8.83, P < 0.01) distinctly increased in the LD group; what's more, CYP7A1 mRNA and protein levels (t = -12.35, P < 0.01) were markedly down-regulated in the LD group. Following OPN-Ab pretreatment, gallstone formation decreased (85% vs. 25%, χ2 = 14.55, P < 0.01), liver TNF-α expression (F = 20.36, P < 0.01) was down-regulated in the LD group, and CYP7A1 expression (F = 17.51, P < 0.01) was up-regulated. Through CD44 and integrin receptors, OPN promoted TNF-α production in macrophage (F = 1041, P < 0.01), which suppressed CYP7A1 expression (F = 48.08, P < 0.01) and reduced liver BA synthesis (F = 119.4, P < 0.01).@*CONCLUSIONS@#We provide novel evidence of OPN involvement in pigmented gallstone pathogenesis in rats.

ABSTRACT

@#Given the opposing effects of Akt and AMP-activated protein kinase (AMPK) on metabolic homeostasis, this study examined the effects of deletion of Akt2 and AMPKα2 on fat diet-induced hepatic steatosis. Akt2–Ampkα2 double knockout (DKO) mice were placed on high fat diet for 5 months. Glucose metabolism, energy homeostasis, cardiac function, lipid accumulation, and hepatic steatosis were examined. DKO mice were lean without anthropometric defects. High fat intake led to adiposity and decreased respiratory exchange ratio (RER) in wild-type (WT) mice, which were ablated in DKO but not Akt2−/− and Ampkα2−/− mice. High fat intake increased blood and hepatic triglycerides and cholesterol, promoted hepatic steatosis and injury in WT mice. These effects were eliminated in DKO but not Akt2−/− and Ampkα2−/− mice. Fat diet promoted fat accumulation, and enlarged adipocyte size, the effect was negated in DKO mice. Fat intake elevated fatty acid synthase (FAS), carbohydrate-responsive element-binding protein (CHREBP), sterol regulatory element-binding protein 1 (SREBP1), peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), peroxisome proliferator-activated receptor-α (PPARα), PPARγ, stearoyl-CoA desaturase 1 (SCD-1), phosphoenolpyruvate carboxykinase (PEPCK), glucose 6-phosphatase (G6Pase), and diglyceride O-acyltransferase 1 (DGAT1), the effect was absent in DKO but not Akt2−/− and Ampkα2−/− mice. Fat diet dampened mitophagy, promoted inflammation and phosphorylation of forkhead box protein O1 (FoxO1) and AMPKα1 (Ser485), the effects were eradicated by DKO. Deletion of Parkin effectively nullified DKO-induced metabolic benefits against high fat intake. Liver samples from obese humans displayed lowered microtubule-associated proteins 1A/1B light chain 3B (LC3B), Pink1, Parkin, as well as enhanced phosphorylation of Akt, AMPK (Ser485), and FoxO1, which were consolidated by RNA sequencing (RNAseq) and mass spectrometry analyses from rodent and human livers. These data suggest that concurrent deletion of Akt2 and AMPKα2 offers resilience to fat diet-induced obesity and hepatic steatosis, possibly through preservation of Parkin-mediated mitophagy and lipid metabolism.

ABSTRACT

Objective:To compare the efficacy between intramedullary nailing (IMN) and minimally invasive percutaneous pate oteosynthesis (MIPPO) in the treatment of distal tibial fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database, Pubmed, Embase, Cochrane, and Web of Science databases were searched by computer for publications on IMN and MIPPO in the treatment of distal tibial fractures published in official journals at home and abroad from January 2010 to August 2020. The studies included were evaluated by 2 authors using the Cochrane collaboration’s tool for assessing risk of bias. The main extraction indexes were operation time, union time, superficial infection, deep infection, malunion, delayed union or nonunion, and soft tissue irritation. Review Manager 5.3 software was used for data analysis.Results:A total of 7 studies with 653 patients were included, with 325 in the IMN group and 328 in the MIPPO group. Meta analysis showed the following: operation time in the IMN group was significantly shorter than that in the MIPPO group ( MD=-10.75, 95% CI:-19.92~-1.58, P=0.02); superficial infection rate in the IMN group was significantly lower than that in the MIPPO group ( RR=0.58, 95% CI: 0.39~0.88, P=0.01); fracture malunion rate in the IMN group was significantly higher than that in the MIPPO group ( RR=1.87, 95% CI: 1.15~3.04, P=0.01). Concerning soft tissue irritation, incidence of anterior knee pain in the IMN group was significantly higher than that in the MIPPO group ( RR=16.98, 95% CI: 3.30~87.34, P=0.0007) while incidence of soft tissue irritation at the fracture site in the IMN group was significantly lower than that in the MIPPO group ( RR=0.13, 95% CI: 0.04~0.40, P=0.0004). There were no significant differences between the 2 groups in fracture healing time, deep infection rate, delayed union rate or nonunion rate ( P>0.05). Conclusions:Although both IMN and MIPPO are fine treatments of distal tibial fractures, IMN may be superior in prevention of superficial tissue infection but prone to anterior knee pain while MIPPO may be superior in prevention of malunion but prone to soft tissue irritation at the fracture site. Therefore, MIPPO is suggested in cases with fine pretibial soft tissues while IMN is used to reduce soft tissue infection otherwise.

ABSTRACT

Objective:To explore the tricuspid annular plane systolic excusion(TAPSE) in children with left-to-right shunt after congenital heart disease surgery and to understand the early systolic function of right heart in thesepatient.Methods:From June 2018 to December 2018, a prospective study was conducted in 20 infants after repair of left-to-right shunt congenital heart disease, including 10 males(50%) and 10 females(50%) , aged from 1 to 12 months, with a median of 4.5(2.0, 6.8) months, a body mass of 3.0-9.0 kg with median of 6.0(3.7, 7.7) kg.On the first postoperative day, blood was taken from central venous for N-terminal pro-B-type natriuretic peptide(NT pro-BNP) test, TAPSE and left ventricular ejective fraction(LVEF) was measured by echocardiography.The effects of aortic occlusion time, cardiopulmonary bypass time, preoperative pneumonia and preoperative heart failure on TAPSE were compared. The relationship between TAPSE and heart rate, systolic pressure, central venous pressure, vasoactive drug score, endotracheal intubation time, detention time in intensive care unit, NT pro-BNP and LVEF after operation was analysed.Results:The aortic cross-clamping time was 15-87 minutes, with median 31(28, 50) minutes. The cardiopulmonary bypass time was 35-117 minutes, with an average of(68±22)minutes. The time of tracheal intubation was 4-117 hours, with an average of(50±35) hours. The stay time in CICU was 1-14 days, with a median of 5(2, 7) days.The LVEF was 0.18-0.66, with median 0.53(0.42, 0.57). The TAPSE was 2.0-10.0 mm, with an average of(5.2±2.0) mm. On the first day after operation, NT pro-BNP was 1 548-35 000 pg/ml, with an average of(9 446±8 130) pg/ml.TAPSE was negatively correlated with postoperative intubation time( r=-0.576, P= 0.007) and detention time in ICU( r=-0.765, P=0.000), and positively correlated with postoperative LVEF( r=0.461, P=0.041)( P<0.05). TAPSE was negatively correlated with heart rate( r=-0.303, P=0.193), central venous pressure( r=-0.425, P=0.062), vasoactive drug score( r=-0.418, P=0.067) and NT Pro BNP( r=-0.348, P=0.132), and positively correlated with systolic pressure( r=0.146, P=0.54), but there was no statistical significance in each item.Compared with patients with TAPSE≥5mm, the detention time and tracheal intubation time were longer than those TAPSE<5 mm, the central venous pressure and NT-pro BNP was higher than those TAPSE<5 mm( P<0.05), the difference was statistically significant, other indicators had no significant difference. Conclusion:It is simple and feasible to measure TAPSE by echocardiography in children after operation with left-to-right shunt congenital heart disease.TAPSE decreased postoperatively suggested that the function of right ventricle decreased at the early stage after surgery, and with left ventricle systolic function decreased, which eventually led to the increase of NT pro-BNP, the need for higher doses of vasoactive drug support, longer tracheal intubation time and the stay time in CICU.Attention should be paid to the right heart function of children after congenital heart surgery.

ABSTRACT

Objective:To investigate the prognostic significance of introtumoral and peritumoral lymphangiogenesis in colorectal cancer.Methods:Lymphangiogenesis of 120 colorectal cancer specimens, as measured by lymphatic vessel density (LVD), were examined by immunostaining for podoplanin, a lymphatic specific marker. The mean number of lymphatic vessel in three hotspots was calculated in intratumoral and peritumoral areas as intratumoral LVD (LVDit) and peritumoral LVD (LVDpt) respectively. The association of LVDit and LVDpt with the clinicopathologic findings and prognosis were investigated.Results:Compared to the peritumoral lymphatics, the intratumoral lymphatics were small, collapsed and irregular. LVDit was positively correlated with tumor size ( t=2.673, P=0.009), tumor histologic grade ( t=-2.296, P=0.023), and overall survival (χ 2=4.386, P=0.036). LVDpt was associated with lymph node metastasis ( t=-4.053, P<0.001), tumor stage ( t=4.740, P=0.004) and overall survival (χ 2=5.806, P=0.016). Conclusions:LVDpt played an important role in lymph node metastasis, while LVDit was more correlated with tumor growth and histopathologic differentiation. Both LVDs contribute to colorectal cancer progression and predict poor prognosis.

ABSTRACT

Objective:To explore the imaging manifestation and the value of imaging follow-up in Takayasu arteritis with pulmonary artery involvement in children.Methods:The data of Takayasu arteritis with pulmonary artery involvement in 7 children in Children Hospital, Capital Institute of Pediatrics from July 2014 to June 2019, were summarized retrospectively, including 1 boy and 6 girls. There were 6 children under 1 year old, the age ranged from 2 to 7 months and the median age was 3 months old. Another child was 12 years old. CT images of all cases in the initial diagnosis and during the follow-up were reconstructed. The diameters and wall thickness of arteries were observed, including ascending aorta, main pulmonary artery, left and right pulmonary artery and each lobe pulmonary artery. The diameter ratio of main pulmonary artery to ascending aorta (MPA/AAO) was calculated. The pulmonary artery pressure, the diameters of left and right coronary artery were measured using echocardiography and compared in the initial diagnosis and during the follow-up.Results:All the 7 cases showed main pulmonary artery, left and right pulmonary artery widened, 6 cases showed lobe pulmonary arteries widened, 2 cases showed main pulmonary artery, left and right pulmonary artery wall thickened, and 6 cases showed lobe pulmonary arteries wall thickened. All the 7 cases showed MPA/AAO>1 in the initial diagnosis, but only 1 case (12-year-old girl) presented pulmonary hypertension from echocardiography. All the 7 cases showed coronary artery dilated in different degrees and ranges in the initial diagnosis, including 3 cases with bilateral coronary artery dilatation and 4 unilaterally. Five children were followed up and showed improvement of pulmonary artery dilatation in 4 cases and progress in 1 case. MPA/AAO decreased in 4 cases and increased in 1 case. The pulmonary hypertension of the 12-year-old patient decreased during the follow-up, and the MPA/AAO also decreased from 1.64 to 1.01. Coronary artery dilatation decreased in 4 of 5 cases during the follow-up.Conclusion:CT imaging can clearly show pulmonary arteries, which plays an important role in the diagnosis and assessment of the treatment effect in Takayasu arteritis with pulmonary artery involvement in children.

ABSTRACT

BACKGROUND@#The tyrosine kinase inhibitors (TKI) treatment of non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutation may have a positive effect, but most patients may develop drug resistance, therefore, the detection of the developing time in drug resistance and the research of the mechanism of drug resistance are need to be solved. While the emerge of next generation sequencing (NGS) have make it possible. The aim of this study is to monitor the efficacy of targeted therapy by studying the variation of circulating tumor DNA (ctDNA) mutation frequency and gene mutation spectrum through the targeted therapy.@*METHODS@#Our center enrolled 22 patients with EGFR mutation detected by tissue or peripheral blood, and collect 8 mL of peripheral blood of the patients for ctDNA sequencing in different phases, before systematic prior treatment, followed-up by 2 months and disease progression after TKI administration.@*RESULTS@#Patients with EGFR gene mutation may acquire a longer median survival time after receiving targeted drug therapy, due to the drop of mutation abundances, while the therapy may have a minor effect in patients which their mutation abundances have slightly decreased compared to the statistics before the cession (P=0.015,3). The significantly reduced group median progression was associated with a longer survival [progression free survival (PFS)=390 d]. At the same time, we found out that when related to TP-53 gene mutation, the effect of targeted drug therapy for EGFR-sensitive mutation was unsatisfactory (the median PFS was 120 d compared with 630 d, P=0.000,2).@*CONCLUSIONS@#Patients who has lower mutation abundance with EGFR sensitive mutations after TKI treatment may have a longer survival period (P<0.05), and the mutation abundance were not significantly dropping or accompanied by other mutations may indicating TKI resistance.

Objective@#To understand the epidemiologic characteristics of fall in the elderly in Shanghai, as well as the differences between urban and rural areas, and provide evidence for targeted fall prevention and intervention.@*Methods@#From January to March in 2017, a questionnaire survey was conducted in the elderly aged 60 or above selected from 7 urban communities and 6 rural communities in Shanghai to understand the epidemiologic characteristics of fall in the elderly and analyze the gender and urban-rural differences.@*Results@#In urban area, a total of 3 386 elderly people were surveyed, in whom 441 (13.0%) had fall and 261 (7.7%) were injured after fall. In rural area, a total of 2 826 elderly people were surveyed, in whom 320 (11.3%) had fall and 169 (6.0%) were injured after fall. Fall risk in women were higher than that in men in both urban and rural areas with OR of 1.62 (95%CI: 1.42-1.86) and 1.16 (95%CI: 1.38-1.98) respectively, but the differences of fall related injury were not significant. Compared with urban areas, fall risk and fall related injury risk were both lower in rural areas with OR of 0.86 (95%CI: 0.73-0.99) and 0.74 (95%CI: 0.56-0.99). Compared with urban areas, men had lower risk for fall, and women had lower risk for fall related injury with OR of 0.68 (95%CI: 0.51-0.90) and 0.66 (95%CI: 0.47-0.93) respectively. Fall mainly occurred at home. Fall in urban area more frequently occurred on stairs, and fall in rural area more frequently occurred during farming. More than 60% of the falls had environmental risk factors. Slippery ground and uneven ground were main reasons. The incidence of fracture resulted from fall was high indicated by 89 fracture cases in urban areas (28.2%) and 64 fracture cases in rural areas (36.1%).@*Conclusions@#The risk for fall in Shanghai had gender and urban-rural differences. Targeted intervention should be conducted according to the characteristics of fall in the elderly.

ABSTRACT

Hepatocellular carcinoma (HCC) is the most common malignant tumor, and the mortality rate remains high, which seriously affects human health. Due to its complicated etiology, the diagnosis and treatment methods are limited, which brings great confusion to patients and physicians. The discovery of miRNAs has helped diagnose, treat, and prognose HCC. This article reviews the role of miRNAs in the diagnosis, prognosis and treatment of HCC.

ABSTRACT

Objective To investigate the relationship between fragmented QRS (fQRS) complex and the early left ventricular remodeling or heart function in patients with acute myocardial infarction(AMI).Methods A total of 76 patients with AMI hospitalized in CCU of the Second Hospital of Tianjin Medical University were enrolled in the study.Patients were divided into fQRS group (n=29) and non-fQRS group (n=47). The clinical data including ECG, laboratory indicators, coronary angiography results and real-time three-dimensional (RT-3D) echocardiography parameter were collected in two groups.The relationship between fQRS and baseline data,fQRS and RT-3D echocardiography parameter were analyzed.At the same time,the influencing factors of left ventricular remodeling and heart function were discussed in the study. Results Compared with non-fQRS group, left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV)were significantly higher,and left ventricular ejection fraction(LVEF)was significantly lower in fQRS group(P<0.05).Several three-dimensional parameters including Tmsv16-SD(%)and Tmsv 16-Dif(%)were significantly higher in fQRS group than those in non-fQRS group(P<0.05).There were no significant differences in Tmsv 16-SD(ms),Tmsv 12-SD(ms),Tmsv 12-SD(%),Tmsv 6-SD(ms),Tmsv 6-SD(%),Tmsv 16-Dif(ms),Tmsv 12-Dif(ms),Tmsv 12-Dif(%),Tmsv 6-Dif(ms)and Tmsv 6-Dif(%)between two groups.Logistic regression analysis showed that fQRS and Gensini scores had effects on heart function.At the same time,fQRS was an independent predictor for left ventricular remodeling. Conclusion Left ventricular remodeling is more obvious in patients with acute myocardial infarction complicated with fQRS,and fQRS can predict left ventricular remodeling better.

ABSTRACT

Thrombospondin-1 (TSP-1) is widely distributed in human tissues and is important in inhibiting angiogenesis.It also occupies an indispensable position in the formation, growth, differentiation, and metastasis of tumors in different tissues.TSP-1 plays an important role in the occurrence and development of various types of tumors. The inhibitory effect of TSP-1 on the angiogenesis and tumor development of oral and maxillofacial malignant tumors has been demonstrated in recent years. This paper reviews the findings and progress of TSP-1 research involving all kinds of tumors as well as oral and maxillofacial malignancies.
