OBJECTIVE: To detect pathogenic variant in a neonate suspected for Cornelia de Lange syndrome (CdLS). METHODS: Potential mutations of CdLS-related genes (NIPBL, SMC1A, SMC3, RAD21 and HDAC8) were detected by high-throughput target region capture and next-generation sequencing. Suspected variants was verified by Sanger sequencing. RESULTS: The child was found to harbor a heterozygous splice site variant, c.6109-1G>A, of the NIPBL gene. Sanger sequencing suggested that neither parent has carried the same variant, suggesting that it was de novo. The variant was unreported by HGMD and ExAC database, and was predicted to alter an acceptor splicing site. No pathogenic variants of SMC1A, SMC3, RAD21 and HDAC8 genes were detected. CONCLUSION The heterozygous c.6109-1G>A splicing variant of the NIPBL gene may underlie the disease in this child. Above finding has expanded the variant spectrum of the NIPBL gene.

Objective: To understand HIV infection status and characteristics of non-remunerated blood donors in Hangzhou. Methods: HIV antibody test were conducted for non-remunerated blood donors in Hangzhou and their demographic and epidemiological information were collected from 2008-2017. χ² test for trend (liner by liner association chi square test) was used for the comparison of the HIV infection trends in each year. Results: A total of 1 461 129 non-remunerated blood donors were surveyed in Hangzhou during 2008-2017, and 260 blood donors were HIV positive. Most HIV infected blood donors were males (96.5%, 251/260) and aged 18-34 years (72.7%, 189/260). Among 260 HIV positive blood donors, those reporting repeated non-remunerated blood donation accounted for 36.9% (96/260), those reporting homosexual transmission accounted for 53.5% (139/260) and those reporting heterosexual transmission accounted for 44.6% (116/260). The HIV infected persons reporting homosexual behaviors were mainly aged 18-34 years (82.0%, 114/139) and unmarried (71.2%, 99/139). Most HIV infected students reported homosexual transmission (88.4%, 23/26). The crude HIV positive rate was 0.8/10 000-2.5/10 000, the differences in annual HIV positive rate had no significance (trend χ²=2.355, P=0.125). The crude HIV positive rate in male blood donors aged 18-24 years increased from 1.1/10 000 in 2008 to 3.7/10 000 in 2017, the difference was significant (trend χ²=5.175, P=0.023). Standardized HIV positive rate was 0.9/10 000-2.4/10 000. Conclusions HIV infection rate was low in non-remunerated blood donors in Hangzhou during 2008-2017. Most HIV infected persons were males and aged 18-34 years. Heterosexual and homosexual contacts were the major transmission routes. The HIV positive rate in males aged 18-24 years showed an increase trend.

Objective To investigate the effects of enteral immunonutrition supplemented with omega-3 polyunsaturated fatty acid (ω-3 PUFA) on inflammatory response,intestinal mucosal barrier function and the prognosis in patients with severe traumatic brain injury (sTBI).Methods 122 patients of sTBI hospitalized between January 2015 and December 2016 were randomly divided into experimental group (ω-3 PUFA,n=61) and control group (n =61).The serum levels of tumor necrosis factor-α (TNF-α),interleukin (IL)-6 and neuron specific enolase (NSE) were tested with enzyme linked immunosorbent assay.Meanwhile,D-lactate acid and intestinal fat acid binding protein (I-FABP) were evaluated by enzymology spectrophotometer method.After 14 days of treatment,the Glasgow Coma Scale (GCS) scores,Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ scores and prognoses of both groups were compared.Results The serum levels of inflammatory factors (TNF-α and IL-6),intestinal mucosal barrier function indicators (D-lactate acid and I-FABP) and NSE proteins significantly increased after sTBI (P =0.01).Compared with the control group,the experimental group on day 3 had significantly lower serum levels of inflammatory factors [TNF-α:(107.77± 19.79) μg/Lvs.(151.76±21.65) μg/L,P=0.01;IL-6:(76.85±7.15) μg/Lvs.(105.27±10.12) μg/L,P=0.01] and intestinal mucosal barrier function indicators [D-lactate:(69.81 ±6.32) μg/L vs.(89.80± 8.75) μg/L,P=0.03;I-FABP:(40.81±6.73) μg/Lvs.(56.60±8.58) μg/L,P=0.01].On day 7,the experimental group had significantly lower expression of NSE proteins than the control group [(13.63± 2.53) μg/L vs.(19.12±3.00) μg/L,P=0.02].The experimental group received better prognosis compared to the control group on day 14 [GCS scores:(9.74±0.76) vs.(8.44±0.53),P=0.04;APACHE Ⅱ scores:(14.67±1.37) vs.(17.53±1.47),P=0.03].The experimental group also had fewer days in hospitalization [(19.37±2.27) d vs.(25.42±2.61) d,P=0.01].Conclusion Enteral immunonutrition supplemented with ω-3 PUFA can effectively regulate the inflammatory response,and reduce impairment to the intestinal mucosal barrier function and damage to neurons in patients with sTBI.
