OBJECTIVETo study the ECG features in children with dilated cardiomyopathy (DCM), and related factors for the occurrence of arrhythmia secondary to DCM.
METHODSData from 68 children with DCM from January 1998 to March 2011 were studied. The children were classified into three groups: severe arrhythmia (n=42), non-severe arrhythmia (n=20) and non-arrhythmia (n=6). Left ventricular end diastolic diameter (LVED), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were compared.
RESULTSAbnormal ECG results were found in all of the 68 children with DCM. Sinus tachycardia (91%) and ectopic pulsatile (86%) were common. LVED in the severe arrhythmia group (74±6 mm) was greater than that in the non-severe arrhythmia group (65±4 mm; P<0.05) and non-arrhythmia group (61±3 mm; P<0.05). LVED in the non-severe arrhythmia group was also greater than that in the non-arrhythmia group (P<0.05). LVEF and LVFS in the severe arrhythmia group were (30±11)% and (22±4)%, respectively, which were lower than those in the non-severe arrhythmia group[(37±12)% and (28±5)%, respectively]and non-arrhythmia group[(45±9)% and (34±7)%, respectively](P<0.05). There were also significant differences in the LVEF and LVFS between the non-severe arrhythmia and non-arrhythmia groups (P<0.05).
CONCLUSIONSThe common abnormal ECG findings are sinus tachycardia and ectopic pulsatile in children with DCM. Arrhythmia is one of the main clinical manifestations of DCM. The occurrence of arrhythmia is associated with the left ventricular size and heart function.

OBJECTIVETo study the expression of connective tissue growth factor (CTGF) in the myocardial tissue of mice with viral myocarditis (VMC).
METHODBalb/c mice were infected with coxsackie virus B3 (CVB3) to establish VMC model. The mice were divided into control group (n = 50) and VMC group (n = 50). on days 4, 7, 14 and 21 after infection, heart specimens of 8 mice were randomly taken and examined after HE staining for myocardial necrosis and cellular infiltration. The area of positive Masson stained myocardium collagen fibers was measured, and collagen volume fraction (CVF) was measured. Then the level of serum creatine phosphokinase-MB (CKMB) was determined. The levels of CTGF and TGF-β₁ were detected by streptavidin peroxidase immunoperoxidase technique. Expression of CTGF and TGF-β₁ were detected with reverse transcription-polymerase chain reaction (RT-PCR). At the same time, the correlations were analyzed.
RESULT(1) The level of CKMB peaked on day 7, and decreased afterwards (455.45 ± 37.95, 606.95 ± 35.64, 573.62 ± 42.90, 308.60 ± 20.49, respectively, 4 - 21 d points), in which 4, 7, 14 d points, there was significant difference compared with control group (t = 6.144, 12.558, 11.182, respectively, P < 0.01). (2) CVF increased significantly on day 14 (8.22 ± 1.95, t = 4.486, P < 0.01) and day 21 (9.46 ± 1.87, t = 4.486, P < 0.01) in VMC group. (3) Measured by streptavidin peroxidase immunoperoxidase technique, the levels of CTGF (171.50 ± 10.25, 141.70 ± 10.863, 110.35 ± 11.051, 81.05 ± 10.190, respectively, 4 - 21 d points) and TGF-β₁ (184.90 ± 11.480, 150.25 ± 9.915, 103.50 ± 10.455, 84.15 ± 9.848, respectively, 4 - 21 d points) increased after day 4 in VMC (P < 0.01). (4) Measured by RT-PCR, the expression of CTGF mRNA and TGF-β₁ increased in VMC group, and the increase was enhanced with the disease development (P < 0.01). (5) The expression of CTGF and TGF-β₁ was positively linearly correlated (r = 0.987, P < 0.01), the expression of CTGF was negatively correlated with CVF (r = -0.901, P < 0.01), but the expression of CTGF was detected earlier than myocardial fibrosis.
CONCLUSIONThe increase of CTGF expression was associated with the severity of myocardial fibrosis in VMC. These results suggest that abnormal expression of CTGF may take part in the development of fibrosis in VMC.

BACKGROUNDHepatic ischemia-reperfusion (I/R) injury occurs in many clinical procedures. The molecular mechanisms responsible for hepatic I/R injury however remain unknown. Sphingolipids, in particular ceramide, play a role in stress and death receptor-induced hepatocellular death, contributing to the progression of several liver diseases including liver I/R injury. In order to further define the role of sphingolipids in hepatic I/R, systemic analysis of sphingolipids after reperfusion is necessary.
METHODSWe investigated the lipidomic changes of sphingolipids in a rat model of warm hepatic I/R injury, by delayed extraction matrix-assisted laser desorption ionization time-of-flight mass spectrometry (DE MALDI-TOF-MS).
RESULTSThe total amounts of ceramide and sphingomyelin and the intensity of most kinds of sphingolipids, mainly sphingomyelin, significantly increased at 1 hour after reperfusion (P < 0.05) and reached peaks at 6 hours after reperfusion (P < 0.01) compared to controls. Six new forms of ceramide and sphingomyelins appeared 6 hours after reperfusion, they were (m/z) 537.8, 555.7, 567.7, 583.8, 683.5 and 731.4 respectively. A ceramide-monohexoside (m/z) 804.4 (CMH(d18:1C22:1+Na)(+)) also increased after reperfusion and correlated with extent of liver injury after reperfursion.
CONCLUSIONSThree main forms of sphingolipids, ceramide, sphingomyelin and ceramide-monohexoside, are related to hepatic I/R injury and provide a new perspective in understanding the mechanisms responsible for hepatic I/R injury.

BACKGROUND: Vitrified cryopreservation is a novel method for specimen preservation, which has a potential application value in the establishment of tumor biopsy biobank. OBJECTIVE: To investigate the effectiveness of vitrified cryopreservation and the feasibility in the establishment of tumor biopsy biobank. METHODS: The fresh biopsy specimens of liver metastasis from rectal cancer were randomized into vitrified cryopreservation and control groups. Then, the biopsy specimens from each group were implanted subcutaneously into the mouse back to establish the humanized mouse xenograft model. The biological characteristics and histological changes of tumor tissues in each group were detected by Calcein-AM/Hoechst33342 staining, as well as immunohistochemistry and hematoxylin-eosin staining. Totally 105 biopsy tissues of liver metastasis from rectal cancer were preliminarily collected and cryopreserved to establish the tumor biopsy biobank. RESULTS AND CONCLUSION: No significant differences in biological viability or histological features of tumor biopsy was detected before and after cryopreservation (P > 0.05), suggesting that vitrified cryopreservation can effectively preserve tumor biopsy and is favorable for the establishment of tumor biopsy biobank.

Objectives: To investigate the clinical value of adjuvant chemotherapy(ACT) in patients with intrahepatic cholangiocarcinoma(ICC) who underwent radical resection and to explore the optimal population that can benefit from ACT. Methods: A retrospective cohort study method was adopted. The clinical and pathological data of 685 patients with ICC who underwent curative intent resection in 10 Chinese hepatobiliary surgery centers from January 2010 to December 2018 were collected;There were 355 males and 330 females. The age(M(IQR)) was 58(14) years (range: 22 to 83 years). Propensity score matching(PSM) was applied to balance the differences between the adjuvant and non-adjuvant chemotherapy groups. Log-rank test was used to compare the prognosis of the two groups of patients. A Bayesian network recurrence-free survival(RFS) prediction model was constructed using the median RFS time (14 months) as the target variable, and the importance of the relevant prognostic factors was ranked according to the multistate Birnbaum importance calculation. A survival prognostic prediction table was established to analyze the population benefiting from adjuvant chemotherapy. Results: Among 685 patients,214 received ACT and 471 did not receive ACT. A total of 124 pairs of patients were included after PSM, and patients in the ACT group had better overall survival (OS) and RFS than those in the non-ACT group(OS: 32.2 months vs. 18.0 months,P=0.003;RFS:18.0 months vs. 10.0 months,P=0.001). The area under the curve of the Bayesian network RFS prediction model was 0.7124. The results of the prognostic factors in order of importance were microvascular invasion (0.158 2),perineural invasion (0.158 2),N stage (0.155 8),T stage (0.120 9), hepatic envelope invasion (0.090 3),adjuvant chemotherapy (0.072 1), tumor location (0.057 5), age (0.042 3), pathological differentiation (0.034 0), sex (0.029 3), alpha-fetoprotein (0.028 9) and preoperative jaundice (0.008 5). A survival prediction table based on the variables with importance greater than 0.1 (microvascular invasion,perineural invasion,N stage,T staging) and ACT showed that all patients benefited from ACT (increase in the probability of RFS≥14 months from 2.21% to 7.68%), with a more significant increase in the probability of RFS≥14 months after ACT in early-stage patients. Conclusion: ACT after radical resection in patients with ICC significantly prolongs the OS and RFS of patients, and the benefit of ACT is greater in early patients.

Objective: To summarize the management and short-term outcomes of neonates delivered by mothers infected with SARS-CoV-2 Omicron variant. Methods: A retrospective study was performed on 158 neonates born to mothers infected with SARS-CoV-2 Omicron variant admitted to the isolation ward of Children's Hospital of Fudan University from March 15th, 2022 to May 30th, 2022. The postnatal infection control measures for these neonates, and their clinical characteristics and short-term outcomes were analyzed. They were divided into maternal symptomatic group and maternal asymptomatic group according to whether their mothers had SARS-CoV-2 symptoms. The clinical outcomes were compared between the 2 groups using Rank sum test and Chi-square test. Results: All neonates were under strict infection control measures at birth and after birth. Of the 158 neonates, 75 (47.5%) were male. The gestational age was (38+3±1+3) weeks and the birth weight was (3 201±463)g. Of the neonates included, ten were preterm (6.3%) and the minimum gestational age was 30+1 weeks. Six neonates (3.8%) had respiratory difficulty and 4 of them were premature and required mechanical ventilation. All 158 neonates were tested negative for SARS-COV-2 nucleic acid by daily nasal swabs for the first 7 days. A total of 156 mothers (2 cases of twin pregnancy) infected with SARS-CoV-2 Omicron variant, the time from confirmed SARS-CoV-2 infection to delivery was 7 (3, 12) days. Among them, 88 cases (56.4%) showed clinical symptoms, but none needed intensive care treatment. The peripheral white blood cell count of the neonates in maternal symptomatic group was significantly higher than that in maternal symptomatic group (23.0 (18.7, 28.0) × 109 vs. 19.6 (15.4, 36.6) × 109/L, Z=2.44, P<0.05). Conclusions: Neonates of mothers infected with SARS-CoV-2 Omicron variant during third trimester have benign short-term outcomes, without intrauterine infection through vertical transmission. Strict infection control measures at birth and after birth can effectively protect these neonates from SARS-CoV-2 infection.
