Objective To investigate the risk factors of low birth weight infants with food allergy.Methods Forty-nine food allergy children who had been admitted to the neonatal intensive care unit(NICU) of Peking University Third Hospital from Jan.1,2007 to Dec.31,2011 and followed up in the Pediatrics Allergy Clinic after discharged from hospital were involved as food allergy group.Forty-nine children who had been admitted to the NICU of Peking University Third Hospital at the same time and followed up in the Child Health Care Clinic after discharged from hospital but had no manifestations of food allergy were selected by stratified sampling as control group.A questionnaire was designed to record the children's gender,gestation age,mode of delivery,feeding patterns after discharging from hospital,tobacco and alcohol consumption of their parents,allergy history of their parents,the intake of egg of the mother during lactation and the children's introduction of egg.At the same time,their hospital notes were investigated.The diseases they had and the application of parental nutrition,pulmonary surfactant and ventilator were all analyzed.Quantitative data were analyzed with Chi-square,qualitative data were analyzed with t-test.The risk factors of food allergy of the low birth weight infants were examined by unconditional Logistic regression.Results The birth weight,gender,mode of delivery,feeding patterns after discharging from hospital,parents,exposure to tobacco smoke and alcohol,the intake of egg of the mother during lactation and the children's introduction of egg between the 2 groups were no significantly different.The diseases they got and the application of parental nutrition,pulmonary surfactant and ventilator when they in hospital were no significantly different,too.The gestation age,parental history of allergy between the 2 groups were significantly different.The proportion of children of 33-35 weeks and 36-37 weeks gestation age in food allergy group were significantly higher than those in control group,while the 29-32 weeks gestation age were significantly lower than those in control group (x2 =10.312,P =0.016 ;x2 =20.753,P =0.000).But by unconditional Logistic regression analysis,only the one or both parents,history of allergy was the risk factor for the development of food allergy of the low birth weight infants(OR =5.574,P =0.004;OR =14.487,P =0.000).Conclusion Parents history of allergy is related to the development of food allergy of the low birth weight infants.

OBJECTIVE: To study on the expression and clinical significance of interleukin 10 receptor 1(IL-10R1)in T lymphocytes in peripheral blood of children with food allergy. METHODS: The food allergy group included 50 cases of children admitted in Department of Pediatrics of Peking University Third Hospital from July 1,2017 to December 31,2017 and were diagnosed with food allergy. A total of 25 cases of healthy children who visited Child Health and Development Center of Peking University Third Hospital in the same period with no food allergy manifestation were selected as a healthy control group. The clinical manifestations of food allergy in different age groups were compared.Flow cytometry was used to examine the expression of IL-10R1 in CD4~+T cells and CD8~+T cells in peripheral blood and the MFI. According to the results of allergen specific Ig E test,the food allergy children were classified as allergen specific Ig E positive group and negative group. The expression of l L-10R1 in the CD4~+T lymphocytes and CD8~+T lymphocytes in peripheral blood and the MFI of the two groups were compared. A severity index of clinical symptoms and signs of food allergy was used to grade illness severity of food allergy children. Then it analyzed the correlation between the expression rates of IL-10R1 in CD4~+T cells and CD8~+T cells in peripheral blood and the scores. RESULTS: The expression rates and MFI of IL-10R1 in CD4~+T cells in peripheral blood of food allergy group were lower compared to the control group. The median expression rates and MFI were 40.23 versus 45.32,12.18 versus 17.69(Z=-2.506,-5.547,P=0.012,0.000,respectively). The expression rates and MFI of IL-10R1 in CD8~+T cells in the peripheral blood of food allergy group were also lower than the control group. The median expression rates and MFI were 34.50 versus 39.46,12.47 versus 17.28(Z=-4.035,-5.226,P=0.000,0.000,respectively). IL-10R1 expression rates and MFI on CD4~+T cells and CD8~+T cells in peripheral blood of allergen specific Ig E positive group were similar to those of the negative group. The expression rates of IL-10R1 on CD4~+T cells and CD8~+T cells in peripheral blood of children with food allergy had no correlation with the symptom and sign scores of food allergy. CONCLUSION: The decrease of the expression of IL-10R1 in CD4~+T cells and CD8~+T cells in peripheral blood may be associated with food allergy of children;the expression of IL-10R1 may be involved in the pathogenesis of food allergy mediated by Ig E and non-Ig E,but it was not associated with the severity of food allergy.

OBJECTIVETo understand the influencing factors on the death of infants born to HIV infected mothers in areas with high prevalence of HIV/AIDS in China.

METHODSBased on the follow-up cohort study targeting at HIV/AIDS infected pregnant women and their babies initiated in 2004, a survey on the death status and influencing factors on the infants born to HIV/AIDS infected mothers enrolled in this cohort from Jan.2004 to Nov.2007 was carried out during Aug.to Nov.2008 in seven counties of four provinces in China. A total of 498 pairs of HIV-infected mothers and their infants were enrolled and their related information was collected. Single factor and multiple factors Cox model methods were adopted for data analysis.

RESULTSThe total observed person-years of 498 infants was 406.22, among which, 45 infants died, and the mortality density was 110.78 per 1000 child-year. A single factor Cox model showed, the pregnancy in pre-period of HIV/AIDS and HIV/AIDS period (RR = 1.971, 95%CI: 1.143 - 3.396), living status of the pregnancy (RR = 3.062, 95%CI: 1.097 - 8.550), multipara women (RR = 0.517, 95%CI: 0.278 - 0.961), natural childbirth (RR = 0.561, 95%CI: 0.345 - 0.910), premature labor (RR = 5.302, 95%CI: 2.944 - 9.547), low birth weight (RR = 4.920, 95%CI: 2.691 - 8.994), mother-child pairs taking antiretroviral drugs (RR = 0.227, 95%CI: 0.121 - 0.428) and infants infected HIV (RR = 5.870, 95%CI: 3.232 - 10.660) could affect the infants death. The death of HIV-exposed infants was influenced by various factors. The death risk of infants born to HIV infected mothers who were in the danger of pre-period of HIV/AIDS and HIV/AIDS period was greater than the infants delivered by HIV infected mothers who were in preclinical period of HIV/AIDS (RR = 6.99, 95%CI: 1.92 - 25.64). The death risks were greater in the group that the women whose CD4(+)TLC count number lower than 200 cells/microl (RR = 2.05, 95%CI: 1.01 - 4.15). The infants whose mothers had no ARV treatment had higher possibility to die than the others (RR = 6.17, 95%CI: 1.62 - 23.26). The death risk of premature delivered infants was 2.87 times of mature delivered infants (95%CI: 1.12 - 7.35). The death risk of HIV/AIDS infected infants was 9.87 times of the HIV/AIDS uninfected infants (95%CI: 3.81 - 25.62).

CONCLUSIONSome measurements including improving HIV-infected pregnant women's immunity, reducing mother to child transmission of HIV and premature birth, low birth weight are beneficial to reducing infant mortality.

OBJECTIVETo study clinical characteristics of pediatric SARS cases in Beijing.

METHODSEighteen pediatric cases with SARS diagnosed on admission were analyzed. The cases were admitted to Beijing Children's Hospital and Ditan Hospital (pediatric ward) from April 8 to May 12.

RESULTSThe 18 children aged 5 months to 15 years (10 male and 8 female) had epidemiologically linked findings. Fourteen cases had close contact with SARS patients. Four cases were living in the community where adult SARS patients were found. All the 18 patients but one presented with fever and cough. Most of them had high fever, 2 cases had bradycardia, 2 had diarrhea, and another 2 had tachypnea. Malaise and headache were noted only in 3 cases respectively which were much less frequently seen than in adult patients. Symptoms and signs of the children were much less severe and aggressive than adults cases. Thirteen children had chest radiographic consolidation. Of them, 9 cases had progressive changes after admission, then improved quickly. We did not find significant lower hemoglobin and platelet levels. Most patients had leukopenia and lymphopenia. Serologic test was performed for 15 cases and 8 were positive for SARS virus-IgG and 6 for IgM antibody. Of the 4 cases who had close contact with SARS adults and without chest radiograph abnormal findings, 3 were negative for SARS virus-antibodies. Part of the patients had temporary abnormality of myocardial enzyme and liver function. All these children finally had rapid improvement on chest radiograph. The patients were treated with antiviral agents and corticosteroid. Only two cases required oxygen therapy. No child needed assisted ventilation and no death, nor lung fibrosis occurred. After hospitalization, all patients were improved and discharged when this paper was being written. The average hospital stay of these patients was 14.6 days (6 - 22 days).

CONCLUSIONCompared with adults, pediatric SARS patients seemed to have their own clinical characteristics. The disease in children had lower severity and infectivity than that in adults. The mechanisms of the disease in children should be studied in well-designed clinical trials. Cases like the 4 children who had close contact with SARS adult patients but without chest radiographic changes deserve further studies with the help of more reliable and sensitive etiologic tests.

OBJECTIVETo evaluate the clinical significance of 320-slice CT hepatic artery images in patients with liver transplantation.

METHODSA total of 58 patients underwent CT scanning by 320-slice scanner after liver transplantation. They were divided into 2 groups according to the concentration of contrast media as follows: Group A (27 cases, 350 mgI/ml iopromide), Group B (31 cases, 370 mgI/ml iopromide). Contrast medium was infused at 6 ml/s, with a total dose of 50 ml. Images were generated by dynamic volume scanning and were processed by 4D digital subtraction angiography (DSA) imaging software. The time-density curve (TDC) of the hepatic artery was delineated. The time to peak, peak contrast enhancement were recorded. The physiological parameters such as body weight and height were analyzed.

RESULTS(1) There were no differences in clinical parameters such as age, sex, height, weight, or BMI between groups. The time to peak of hepatic artery of group A and B was (19.71+/-3.11) s and (20.06+/-3.67) s, and had no significant difference. The maximum peak enhancement of hepatic artery in groups B was higher than that group A (P < 0.05). (2) 4D DSA revealed hepatic artery pseudo-aneurysm (n = 2), and hepatic artery mild stenosis (n = 13), moderate stenosis (n = 5), severe stenosis (n = 9) and occlusion (n = 1), segmental moderate and severe stenosis (n = 4), and compensatory circulation with hepatic artery severe stenosis and occlusion (n = 6). hepatoportal arteriovenous fistulas (HPAVF, n = 12), donor-recipient hepatic artery mismatch (n = 3). Hepatic arterial branch are decreased and opened in 15 cases and 8 cases.

CONCLUSION320-slice CT hepatic artery images is safe, noninvasive, and accurate technique to evaluate hepatic arterial complications after liver transplantation.

Objective: To investigate the clinical characteristics and treatment of pancreatic pseudocyst after pegaspargase treatment in children. Methods: The clinical data of 6 children with pancreatic pseudocyst after pegaspargase treatment in the Department of Pediatrics in Peking University Third Hospital from July 2018 to February 2021 were analyzed retrospectively. Results: There were 4 males and 2 females, and their age of onset was 9.5 (5.8, 13.0) years. The total number of pegaspargase applications was 2.5 (2.0, 3.5) times. The course from the last dose of pegaspargase to the onset of pancreatitis was 11.0 (9.0, 17.2) days, and 42.5 (35.0, 129.5) days from the onset of pancreatitis to the diagnosis of pancreatic pseudocyst. Abdominal pain was the most prominent manifestation of pancreatitis (6/6). All of the 6 children were asymptomatic when pancreatic pseudocyst was noted, and were treated conservatively at first, but one case later developed intermittent abdominal distension or nausea after eating. All the cases had pancreatic pseudocyst enlargement during the conservative treatment. Three children were treated with endoscopic ultrasound-guided transgastric drainage, and the cyst disappeared from 10 days to 4 months after the operation. The other 3 children received endoscopic retrograde cholangiopancreatography (ERCP)-guided transpapillary drainage, but one of them turned to surgery due to pancreatic duct stricture, and in the rest 2 children the cyst disappeared at 1 and 3 months after operation respectively. Regarding safety issues, 1 child who received ERCP-guided transpapillary drainage had acute postoperative pancreatitis, which were improved after treatment, and the other 5 had no complications. Conclusions: Pancreatic pseudocyst after pegaspargase chemotherapy can be asymptomatic in the early stage, and should be diagnosed with a history of pegaspargase treatment and timely imaging examination. Conservative treatment is the first choice for asymptomatic pseudocyst. When the pseudocyst enlarges, different endoscopic drainage treatments are required according to whether the pseudocyst is connected with the main pancreatic duct.
