Objective To analyze the preoperative related factors of early weaning of infants with congenital heart disease after operation. Methods From January ,2014 to January ,2017 in Pediatric Cardiology CICU , infants with congenital heart disease were selected as research objects. The clinical data were retrospectively collect ed and the relationship between preoperative influencing factors and postoperative early weaning were analyzed. Early weaning meant mechanical ventilation time was shorter than 24 h and late weaning meant longer than 24 h. Results Single factor analysis showed that early weaning success rate was related to preoperative cardiac function grade 1,NNIS grade 0~1,ASA grade 1,no lung infection and no or mild pulmonary hypertension(average P<0.05). Non conditional logistic regression analysis showed that preoperative heart function grade 1 was an indepen-dent influencing factor,with OR value(95%CI)of 3.9(1.9~7.7). Conclusions In infants with congenital heart disease,preoperative heart function grade 1,NNIS grade 0 ~ 1 ,ASA grade 1,no lung infection and no or mild pulmonary hypertension benefit early withdrawing of ventilator and preoperative cardiac function grade 1 is an inde-pendent factor for early weaning.

Objective: Evaluate GII.4 norovirus infection and blocking effects of serum antibodies against HBGAs binding to GII.4 norovirus of population in oyster culture area, provide references for screening of fully human monoclonal antibody. Methods: Using a random survey method to collect blood and saliva samples in oyster culture area, select serum samples from the inland region of Guangdong as control group. Identification of salivary HBGA receptor phenotype and detection of serum antibody levels between two areas by ELISA. A vitro neutralization model was to determine the efficiency of serum antibodies blocking GII.4 norovirus and HBGA receptors binding. Results: The age were (50.68 ± 15.17), (52.52 ± 15.90) and (51.37 ± 13.32) years old of 2015, 2016 in experimental group, and in control group, respectively. Males accounted for 5.9% (70/195), 36.6%(60/164), 40.8% (69/169) (χ²=0.93, P=0.334). The mean value of serum antibodies Absorbance value was 2.521±0.05 of 2015 and was 2.583±0.045 of 2016 in oyster culture area, the mean value was 2.249±0.05 in control group, there was a statistical difference among three group (F=13.28, P<0.001). The antibody prevalence in the three groups was 100%. BT50 geometric mean titer (GMT) of oyster culture area in 2015 was 423.1±40.11, culture group was 248.2±25.63, there was a statistical difference (t=3.73, P<0.001). Conclusion The population in oyster culture area does have more chance of exposure and infection GII.4 norovirus, Serum antibody of blocking ability in oyster culture areas is better than the general population in inland city. Suggesting that the population is more immunity resistant infected GII.4 norovirus.

We report the successful management of a pregnant woman with para-Bombay phenotype. The woman received routine prenatal check-ups and underwent vaginal delivery in the Affiliated Shenzhen Maternity & Child Healthcare Hospital. Blood grouping at 12 weeks of pregnancy showed that the forward typing of the patient was group O, but reverse typing indicated group AB. Her ABO genotype was determined as ABO*A1.02/B.01. There was c.551-552del AG and c.880-882 del TT in the FUT1 gene, and 357C>T and 716G>A in the FUT2 gene. Thus, her FUT1 genotype was h1/h2 and FUT2 genotype was Se/Se. No significant abnormalities were found in the routine prenatal examination. A male infant was born vaginally at 39 +2 gestational weeks, who was grouped as B-positive without neonatal hemolytic disease. Para-Bombay is a rare blood group. It is necessary to clarify the blood type during prenatal examination and develop a management strategy for those with special blood groups to reduce the incidence of postpartum hemorrhage and ensure safe delivery.

Objective:To observe the effects of early rehabilitation intervention on the short-term outcome of patients with postoperative spinal cord injury after Stanford type A aortic dissection.Methods:Patients with postoperative spinal cord injury after Stanford type A aortic dissection admitted in our hospital from January 2009 to December 2019 were selected. There were 29 males and 8 females. Age ranged from 29 to 54, with an average age of(41.37±12.21) years. The observation group(16 cases) received early rehabilitation treatment in ICU after surgery, while the control group(21 cases) started after admission to rehabilitation center. The Modified Ashworth Scale(MAS), ASIA Lower Extremity Motor Scores(LEMS), Spinal Cord Independence Measure(SCIM Ⅲ) and Modified Barthel Index(MBI) were analyzed to compare the differences of short-term outcome between the two groups.Results:After 28 days, the scores of MAS, SCIM Ⅲ and MBI in the observation group were obviously better than the control group. Compared to the time of admission, the improvements of LEMS, SCIM Ⅲ and MBI in the observation group were significantly greater than that of the control group.Conclusion:Early rehabilitation intervention can further enhance clinical efficacy and improve short-term functional outcome.
