Objective:To compare the effect of extracorporeal membrane oxygenation(ECMO)on pulmonary transplantation(LTx)in patients with idiopathic pulmonary fibrosis(IPF)complicated with pulmonary hypertension(PH).Methods:From January 2017 to December 2020, clinical data were retrospectively reviewed for 112 IPF patients complicated with PH undergoing LTx assisted by venous ECMO(VV-ECMO group, n=68)or venous arterial ECMO(VA-ECMO group, n=44). Gender, age, mechanical ventilation time, oxygenation index, cold ischemic time, preoperative gender, age, smoking history, PO 2, PCO 2, PH degree, NYHA cardiac function grade, right cardiac function, ejection fraction(EF)and complications(hypertension & diabetes)of two groups were compared. Intraoperative approach, operative duration, ECMO transfer time, blood loss, blood transfusion, urine volume, postoperative blood transfusion, mechanical ventilation time, ICU stay time, re-thoracotomy, pulmonary infection, primary graft dysfunction(PGD)and renal insufficiency were recorded. And the effects of two different diversion modes on early postoperative complications and short-term outcomes of LTx were further analyzed by multiple factors. Cox proportional risk model was employed for comparing VV-ECMO and VA-ECMO flow patterns with factors related to recipient survival after transplantation. Results:The preoperative PO 2 of 58.3(51.3, 72.0)mmHg was significantly lower in VV-ECMO bypass group than that of 73.2(63.3, 96.8)mmHg in VA-ECMO group and the difference was statistically significant( P<0.006). Compared with VV-ECMO group, 24(54.5%), 15(34.1%)and 22(50.0%)had NYHA class Ⅲ, severe PH and preoperative right heart enlargement in VA-ECMO group respectively and the differences were statistically significant compared with 17(25.0%), 6(8.8%)and 16(23.5%)in VV-ECMO group( P<0.05 for all). No significant inter-group differences existed in postoperative PGD, postoperative mechanical ventilation time(≥3 d), pulmonary infection, postoperative thoracotomy ratio, postoperative renal insufficiency, ICU stay, hospital stay and other aspects( P>0.05). And 6-month postoperative survival rates of VV-ECMO and VA-ECMO groups were 80.9% and 61.4%, respectively and no significant inter-group difference existed in short-term survival rate(6 months)after adjustment by multivariate Cox regression model( P>0.05). Multivariate statistics indicated that the risk of delayed postoperative withdrawal was 14.452-fold higher in VV-ECMO group than in VA-ECMO group and the inter-group difference was statistically significant(95% CI: 2.448-85.323, P=0.03). Conclusions:No differences exist in postoperative complications or short-term survival rate between IPF recipients with mild PH on VV-ECMO mode and IPF recipients with severe PH on VA-ECMO mode. VV-ECMO flow reversal can delay the transplant back-off time.

OBJECTIVE: To explore the clinical features and genetic etiology for a neonate with Smith-Magenis syndrome (SMS). METHODS: Copy number variation sequencing (CNV-seq) was applied to the neonate and his parents, and the genotype-phenotype correlation was analyzed. RESULTS: On the second day after birth, the neonate had presented with pathological jaundice and immunodeficiency. Cranial MRI revealed ventricular enlargement and enlargement of cisterna magna. At 3 months, the infant has presented with square face, prominent forehead, deep-set eyes, hypertelorism, palpebral fissure upward and button noses. Genetic testing showed that he had carried a 2.9 Mb deletion in 17p11.2 region, seq[GRCh37] del(17)(p11.2)(chr17:16 836 379-19 880 992). The same deletion was not found in either parent. CONCLUSION SMS is mostly diagnosed in child and adulthood, but rarely in neonates. For neonates with SMS, the neurological and behavioral abnormalities have not been shown, but pathological jaundice, CNS abnormalities and immune deficiency may be the characteristics, which require attention of neonatal physicians.

Objective: To investigate potential biomarkers for different types of hand, foot and mouth disease(HFMD). Methods: Nuclear magnetic resonance(NMR)-based metabolomics methods were used to analyze the metabolic differences in serum of HFMD and healthy controls.Partial least squares discriminant analysis(PLS-DA)and orthogonal partial least square discriminant analysis(OPLS-DA)were used for analysis of metabolite profiles.Differential statistical analysis was performed by t tests using GraphPad Prism 5 software. Results: The levels of lipid, leucine, valine, β-hydroxybutyric acid, acetone, glucose, glycoprotein, glycerol, glycine, choline, trimethylamine oxide and lactate in HFMD increased significantly compared with healthy controls, whereas the levels of acetic acid and creatine decreased significantly.Additionally, the level of acetone further increased in the severe type of HFMD compared with the mild type, whereas the levels of lipid and trimethylamine oxide decreased. Conclusion These statistically significant differences are involved in lipid metabolism, glucose metabolism and protein metabolism in different types of HFMD.Lipid, acetone and trimethylamine oxide can be used as potential biomarkers of HFMD.

Objective: To understand the dyslipidemia rate and trend of blood lipid level in an urban community in Hangzhou. Methods: A total of 1 485 urban community residents aged 24 years or older who had participated in health checkup over 6 years, from 2011-2016, were selected by random cluster sampling. Fasting blood Triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) levels were measured in all subjects. A χ² test was used to analyze the dyslipidemia rate trend, and an ANOVA of repeated measurement was conducted to observe the blood lipid level changes. Results: From 2011 to 2016, the total abnormal rates of blood lipids in 1 485 residents were 33.2% (493/1 485), 30.5% (453/1 485), 30.4% (452/1 485), 26.5% (394/1 485), 26.3% (391/1 485), and 25.1% (373/1 485), respectively, which showed a declining trend year-by-year (χ²=36.051, P<0.01). Among these results, however, the high TG rate did not significantly differ from year-to-year (χ²=10.081, P>0.05). The TG, TC, LDL-C, and HDL-C levels statistically differed over the 6 years (F=4.876, 33.033, 170.254, 58.442, respectively, all P<0.01). LDL-C was the highest in 2011 [(3.02±0.29) mmol/L] and the lowest in 2016 [(2.72±0.71) mmol/L], while HDL-C was the highest in 2016 (1.44±0.33 mmol/L) and the lowest in 2011 [(1.35±0.30) mmol/L]. Time-sex group interaction effect analysis: TC and HDL-C levels showed different trends over time between men and women (F=2.556, 4.982, respectively, all P<0.05), and the TC level in the male group was significantly lower than in the female group, since 2012. Interaction effect of time age group: TC and LDL-C levels showed different trends between age groups over time, and the declining trend of TC and LDL-C in the elderly group was more significant than in the young or middle age group (F=10.328, 3.085, respectively, all P<0.01). Conclusions The community population showed an overall improvement in blood lipid levels; however, there was no significant improvement in high TG levels. It is necessary to continue monitoring blood lipid levels in the community, especially to strengthen the prevention and control of high TG levels.

Objective To analyze the correlation between the lung allocation score (LAS) and the risk of early death and complications in patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 275 patients with IPF were retrospectively analyzed. The correlation between LAS and the risk of early death in IPF patients after lung transplantation and the correlation between LAS and complications at postoperative 1 year was assessed by univariate and multivariate Cox regression analyses. Results Among 275 recipients, 62, 83, 95 and 108 cases died within postoperative 30, 90, 180 and 365 d, respectively. LAS was correlated with 30-, 90-, 180- and 365-d fatality of IPF patients (all P<0.05), whereas it was not correlated with the incidence of primary graft dysfunction (PGD) and acute kidney injury (AKI) at 365 d after lung transplantation (both P>0.05). Conclusions LAS is correlated with the risk of early death of IPF patients after lung transplantation. While, it is not correlated the incidence of PGD and AKI early after lung transplantation. Special attention should be paid to the effect of comprehensive factors upon PGD and AKI.
