Immunoglobulin (IgG) glycosylation affects the effector functions of IgG in a myriad of biological processes and has been closely associated with numerous autoimmune diseases, including systemic lupus erythematosus (SLE), thus underlining the pathogenic role of glycosylation aberration in autoimmunity. This study aims to explore the relationship between IgG sialylation patterns and lupus pregnancy. Relative to that in serum samples from the control cohort, IgG sialylation level was aberrantly downregulated in serum samples from the SLE cohort at four stages (from preconception to the third trimester of pregnancy) and was significantly associated with lupus activity and fetal loss during lupus pregnancy. The type I interferon signature of pregnant patients with SLE was negatively correlated with the level of IgG sialylation. The lack of sialylation dampened the ability of IgG to suppress the functions of plasmacytoid dendritic cells (pDCs). RNA-seq analysis further revealed that the expression of genes associated with the spleen tyrosine kinase (SYK) signaling pathway significantly differed between IgG- and deSia-IgG-treated pDCs. This finding was confirmed by the attenuation of the ability to phosphorylate SYK and BLNK in deSia-IgG. Finally, the coculture of pDCs isolated from pregnant patients with SLE with IgG/deSia-IgG demonstrated the sialylation-dependent anti-inflammatory function of IgG. Our findings suggested that IgG influences lupus activity through regulating pDCs function via the modulation of the SYK pathway in a sialic acid-dependent manner.

Objectives:To study the clinical significance of time to positive (TTP) of blood culture for neonatal sepsis.Methods:From August 2016 to June 2019, a retrospective study was conducted in patients with positive blood cultures admitted to the Neonatology Department of our hospital. The patients were assigned into different groups according to the species of pathogen, types of neonatal sepsis and the samples contaminated or not. TTP of different groups were analyzed.Results:A total of 307 cases with positive blood cultures were identified from 10 035 cases with blood culture specimens. Among the 307 cases, 162 were contaminated (the contaminated group) and 145 (1.4%) were diagnosed of neonatal sepsis (the pathogenic group). The proportion of TTP <24 h, 24~<48 h, 48~<72 h and ≥72 h in the 145 sepsis cases were 90.3% (131/145), 7.6% (11/145), 1.4% (2/145) and 0.7% (1/145), respectively. The median TTP was 9.0 h in early-onset sepsis (EOS) group and 11.5 h in late-onset sepsis (LOS) group. The median TTP of the contaminated group was 24.5 (19.9, 30.5)h, which was longer than 11.1 (8.1,16.2)h of the pathogenic group ( P<0.05). The median TTP of Gram (+) group was 14.0 (9.4,18.8)h, which was longer than 9.6 (7.5,11.3)h of Gram (-) group ( P<0.05). The median TTP of fungi group was 32.5 (25.5, 39.0) h, which was longer than 10.6 (8.1, 15.5)h of bacteria group ( P<0.05). Conclusions:Different pathogens has different TTP for neonatal sepsis. If blood culture maintains negative for more than 72 h, empiric use of antibiotics may be discontinued for patients of suspected sepsis without specific clinical manifestations or other lab results.

Objective To study the risk factors of acute bilirubin encephalopathy (ABE) in neonates with severe hyperbilirubinemia (total serum bilirubin ≥ 427.5 μmol/L).Method Clinical information of neonates with severe hyperbilirubinemia admitted to the Neonatal Department of Baoan Maternal and Child Health Hospital in Shenzhen from December 2013 to October 2017 were collected.The enrolled cases were grouped as ABE and the control group (without ABE).The risk factors for ABE were compared between the two groups and the Logistic regression analysis was used to evaluate the independent risk factor.Result A total of 104 neonates were recruited.There were 32 cases in the ABE group and 72 cases in the control group.The level of total serum bilirubin and indirect bilirubin,the ratio of total bilirubin/albumin,the incidence of glucose-6-phosphate dehydrogenase deficiency and metabolic acidosis and sepsis,the rate of using traditional Chinese medicine and the failure of treatment in other hospitals and non-resident population were all significantly higher in the ABE group than the control (P ＜ 0.05).Logistic regression analysis showed that total serum bilirubin (OR =1.013,95％ CI 1.007 ～ 1.020) and sepsis (OR =6.343,95％ CI 1.801 ～22.338) were the independent risk factors for ABE.Conclusion The severe hyperbilirubinemia infants,particularly with sepsis,are at higher risk of developing acute bilirubin encephalopathy.

Objective: To evaluate the impact of primary percutaneous coronary intervention (PPCI) with pre-operative intra-aortic balloon pump (P-IABP) implantation on short and long term prognosis in octogenarian patients of ST-segment elevation myocardial infarction (STEMI). Methods: We performed aretrospectively study in octogenarian STEMI patients treated in our hospital from 2004-01 to 2014-08. The patients were divided into 2 groups: P-IABP group,n=24 and PPCI group,n=73 including 12 patients who received rescue IABP (R-IABP) because of intra- or post-procedural hemodynamic collapse as a subgroup.Major end point events included 1 month and 1-, 2-year post-operative death; major adverse cardiac and cerebral events (MACCE) included 1 month post-operative cardiac shock, new or worsening heart failure (HF), re-infarction and stroke. The predictors causing different endpoint events were identiifed by Cox proportional hazard model analysis. Results: 1 month and 1-, 2-year post-operative death were similar between 2 groups (8.3% vs 16.4%), (16.7% vs 24.7%), (25.0% vs 30.1%) respectively; MACCE incidence was also similar (20.8% vs 30.1%), allP>0.05. Death rates between P-IABP group and R-IABP subgroup were similar at different time points,P>0.05; while MACCE incidence in P-IABP group was lower than R-IABP subgroup (20.8% vs 66.7%),P=0.005 and it was mainly presented by reduced HF occurrence (8.3% vs 41.7%),P=0.003. Coxproportional hazard model analysis indicated that post-operative TIMI lfow<3 grade was the independent predictor for 1 month death (HR=4.79, 95% CI1.59-14.39,P=0.005), complicating diseases as chronic obstructive pulmonary disease, kidney impairment and anemiawere themain independent predictors for 2-year death (HR=3.0, 95% CI 1.37-6.56,P=0.006). Conclusion: PPCI and P-IABP had no signiifcant differencefor short and long term survivalin octogenarianSTEMIpatients. Compared with R-IABP, P-IABP patients had the lower MACC Eincidence at 1 month post-operation .

Objective Our retrospective study was aimed to analyze the clinical significance of microsurgical clipping and intravascular embolization in patients with intracranial aneurysm (IA).Methods Clinical data of 86 patients with IA received treatment at our hospital from February 2010 to November 2014 was retrospectively analyzed.Patients were divided into two groups according to the treatment method, IE group (intravascular embolization,43 cases)and MC group (microsurgical clipping,43 cases).The general information,treatment effect, hospitalization expenses and time and the rate of complication of the patients between two groups were compared.Results There was no sta-tistical difference in general information between two groups (P >0.05).The cure rate of patients in IE group was obviously better than that in MC group (P <0.01).The hospitalization expenses in IE group was lower than that in MC group,and the hospitalization time was shorter than that in MC group,all the differences had statistical significance (P <0.01).The rate of complication in IE group was obviously lower than that in MC group (P <0.01).Conclusion The clinical effect of intravascular embolization was significantly better than microsurgical clipping,which is worth promoting in clinic.

Objective: To make long-term comparison of drug-eluting stent (DES) implantation betweenleft internal mammary artery (LIMA) graft and native vessel in patients with previous coronary artery bypass grafting (CABG).
Methods: A total of 151 patients with anterior wall ischemia because of previous CABG induced LIMA graft lesion who received percutaneous coronary intervention (PCI) in our hospital from 2004-07 to 2012-12 were retrospectively studied. The clinical, coronaryangiography (CAG) and follow-up conditions for DES implantation were analyzed;according to the target vessel, the patients were divided into 2 groups:LIMA group, n=40 and Native vessel (NV) group, which meant all segments of left main to left anterior descending arteries, n=111. Primary end points included target lesion revascularization (TLR), target lesion failure (TLF) as cardiac death, target vessel related non-fatal MI with the composition of TLR and major adverse cardiovascular events (MACE).
Results:The median follow-up time was 30 (10-100) months. The rates of TLR and TLF were similar between 2 groups:(15.0%vs 11.7%, log-rank P=0.65) and (17.5%vs 13.5%, log-rank P=0.63). MACE occurrence in LIMA group was higher than NV group (35.0%vs 18.0%, log-rank P=0.043) which was mainly presented by new non-target vessel revascularization as right coronary artery, left circumlfex and saphenous vein graft(17.5%vs 4.5%, log-rank P=0.014). Cox multivariate analysis indicated that target lesion stent length was the only independent predictor for both TLR (HR=1.03, 95%CI1.00-1.06, P=0.01) and TLF (HR=1.03, 95%CI1.00-1.05, P=0.02);whereas, LIMA-PCI was the only independent predictor for MACE occurrence (HR=3.09, 95%CI1.28-7.60, P=0.012).
Conclusion: The chances of TLR and TLF were similar inpatients with previous CABG by either LIMA or NV, while MACE occurrence was higher in LIMA patients which should be further investigated.

microRNAs combined with specific mRNAs are 19-25 nucleotide-long small-molecule RNA that mediate sequence-dependent post-transcriptional gene expression.Accumulating evidences indicate that microRNAs target critical signal transduction molecules of immune system,and involve in regulation of immune tolerance.Recently,microRNAs have been a potential biomarker,and are widely useded in diagnosis and prognosis of cancer,infectious disease,autoimmune disease,and transplantation.If we can further identify regulatory mechanism of microRNAs and their target genes,which makes possible the successful induction of immune tolerance and exert a huge push on organ transplantation.

The liver injury induced by Polygonum multiflorum Thunb. (PM) was investigated based on idiosyncratic hepatotoxicity model co-treated with lipopolysaccharide (LPS) at a non-hepatotoxic dose. Sprague-Dawley (SD) rats were intragastrically administered with three doses (18.9, 37.8, 75.6 g crude drug per kg body weight) of 50% alcohol extracts of PM alone or co-treated with non-toxic dose of LPS (2.8 mg·kg(-1)) via tail vein injection. The plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were assayed and the isolated livers were evaluated for histopathological changes. The dose-toxicity relationships of single treatment of PM or co-treatment of LPS were investigated comparatively to elucidate the idiosyncratic hepatotoxicity of PM. The results showed that no significant alterations of plasma ALT and AST activities were observed in the groups of solo-administration of LPS (2.8 mg·kg(-1), i.v.) or different dosage (18.9, 37.8 and 75.6 g·kg(-1), i.g.) of PM, compared to normal control group (P > 0.05); while significant elevations were observed in the co-administration groups of PM and LPS. Treatment with LPS alone caused slight infiltration of inflammatory cells in portal area but no evident hepatocytes injury. Co-treatment with LPS and PM (75.6 g·kg(-1), i.g.) caused hepatocyte focal necrosis, loss of central vein intima and a large number of inflammatory cell infiltration in portal areas. When further reduce the dosage of PM, significant increases of plasma ALT and AST activities (P < 0.05) were still observed in co-administration groups of LPS and PM (1.08 or 2.16 g·kg(-1)), but not in LPS or PM solo-administration groups. Nevertheless, the co-treatment of low dosage of PM (0.54 g·kg(-1)) with LPS did not induce any alteration of plasma ALT and AST. In conclusion, intragastric administration with 75.6 g·kg(-1) of PM did not induce liver injury in normal rats model; while the 2 folds of clinical equivalent dose of PM (1.08 g·kg(-1)) could result in liver injury in the LPS-based idiosyncratic hepatotoxicity model, which could be used to evaluate the idiosyncratic hepatotoxicity of PM.
