Objective To test and compare CA19-9,CEA with Specific N-Glycans in early-middle stage pancreatic carcinoma serum to find a better tumor marker in early pancreatic carcinoma .Methods To find the difference of N-Glycans structure ,DSA-FACE was performed in 35 early middle stage pancreatic carcinoma patients and 50 healthy human .Meanwhile ,we tested CA19-9 and CEA in the pancreatic carcinoma patients at the same stage.Result The serum N -glycan profiles of pancreatic carcinoma was identified by the DSA -FACE technique.The results showed that between pancreatic carcinoma patients and healthy persons ,there were significant differences in N -glycans.The peak 13,14 and 17 were the most significant peaks which would be most likely picked as a new tumor marker of pancreatic carcinoma .Taking log(p14 ×p17/p13)as indicator of the ROC curve analysis,and the area under ROC curve was 0.799 ±0.050 with 84.9% sensitivity and 68% speci-ficity.Meanwhile,the sensitivity of CA19-9 was 61.2%,the sensitivity of CEA was 11.7%.Conclusion The Peak 13,14 and 17 are the most significant peaks which would be picked as a new tumor marker of pancreatic carcinoma.Espicially,its sensitivity is superior to CA19-9、CEA for early middle stage patients .

Objective To investigate the structural changes in specific serum N-glycans in pancreatic cancer patients and to identify the specific serum maker of pancreatic cancer.Methods The pancreatic cancer patients who visited the Third Affiliated Hospital of Harbin Medical University from June 201 1 to December 2013 were assigned to preoperative serum group (123 cases)and postoperative serum group (78 cases);healthy controls whose serum samples were collected in the Physical Examination Center were selected as control serum group (271 cases).DNA sequencer-aided fluorophore-assisted carbohydrate electrophoresis (DSA-FACE)was used to analyze serum N -glycans and compare them between the three groups.Results The serum N-glycan profiles in pancreatic cancer patients were identified by DSA-FACE.The results indicated that N-glycan peak 8 in preoperative serum group was significantly lower than those in control serum group (t=2.735,P<0.05)and postoperative serum group (P<0.05),but no significant difference was found between the postoperative serum group and control serum group.Conclusion N-glycan peak 8 can be considered as a serum marker of pancreatic cancer.

Objective To observe the changes of plasma pulmonary surfactant protein-A (SP-A) and serum ferritin (SF) in neonates with mechanical ventilation and its clinical significance in ventilation-induced lung injury (VILI).Methods The study was carried out in 36 neonates with mechanical ventilation and 31 neonates without mechanical ventilation .Plasma SP-A and SF levels in venous blood were mea- sured on 1,24,48,72 hours after mechanical ventilation and 24 hours after mechanical ventilation removal by Western-dot blot and radioimmunoassay (RIA).Plasma SP-A and SF levels of non-mechanical ventilation group were determined at the same time.Results Plasma SP-A levels in neonates on 24,48,72 hours after mechanical ventilation were significantly higher than those of non-mechanical ventilation group[( 2.20? 0.22)vs(1.97?0.29) ?g/L,(2.43?0.28)vs(1.94?0.33) ?g/L,(2.61?0.38)vs(1.80?0.34) ?g/L,respectively P

Objective To explore the role of RBC[Ca2+]i levels in pathogenesis of hypoxic-ischemic encephalopathy (HIE) in neonates. Methods Twenty-eight neonates with moderate and severe HIE hospitalizeal from Jun. 2002 to Mar. 2006 were enrolled the study. The neonates with HIE were given routine treatment and Nimodipine for 7～10 days. Blood samples were collected before treatment and at 72 hours,7～10 days after treatment respectively. The levels of RBC [Ca2+]i were measured by Fura-2/AM. Twenty healthy full-term neonates were studied as controls. Results (1) The levels of RBC [Ca2+] i in the neonates with moderate and severe HIE were significantly higher than that in control group at every time points( P＜0. 05 ,P＜0.01). (2) the levels of RBC[Ca2+]i in the neonates with moderate and severe HIE peaked at 72 hours after treatment,and were still significantly higher than that of control group at 7～10 days after treatment(P＜0. 05). (3) In the neonates with HIE,RBC[Ca2+ ]i levels correlated positively with the severity of HIE ( r = 0. 447, P＜ 0. 05 ). Conclusion RBC [Ca2+ ] i levels are closely associated with pathogenesis of HIE, and may play an important role in the pathogenesis of HIE. Evaluating RBC [ Ca2+] i levels in neonate after birth may provide clinical clues for the early diagnosis and prognosis assessment of HIE.

Objective To explore change of RBC[Ca2+]i levels in neonates with hypoxic-ischemic encephalopathy(HIE)and the influence of nimodipine on RBC[Ca2+]i and its clinical significance.Methods Fifty-eight neonates with moderate and severe HIE were randomly divided into 2 groups including routine treatment group(n=28)and nimodipine group(n=30),and 20 healthy full-term neonates were selected as healthy control group.Based on the routine treatment,nimodipine[2 mg,0.5-1.0 ?g/(kg?min)] was given intravenously in the nimodipine group for 7-10 days.Blood samples were collected before and after treatment for 72 hours and 10-14 days,respectively.The levels of RBC[Ca2+]i were measured by Fura-2 pentakis(acetoxymethyl)ester[Fura-2/AM].The results were analyzed by SPSS 10.0 software.Results 1.The levels of RBC[Ca2+]i in neonates with HIE were significantly higher than those in healthy control group[(2.83?0.36)mmol/L vs(2.15?0.18)mmol/L,P

Objective To explore the characteristics of clinic and epidemiology of neonatal respiratory syncytial virus(RSV) pneumonia in newborn infants.Methods Three hundred and nine neonates(male 196,female 113) who were admitted to children's hospital of Fudan University and identified as having RSV pneumonia from Jan.2004 to Dec.2008 were enrolled.RSV antigen was detected in exfoliated respiratory cells by direct immunofluorescence.All the clinical data were collected and subjects and they were divided into different groups based on path of infection,gestational age and RSV status.Results From case notes over the 5 years,309 eligible neonates with RSV infection were identified.Male term neonates were more likely to acquire infection,as compared to female,1.71.0.The incidence of RSV infection peaked in winter and spring.Compared with community acquired infection group,hospital acquired infection group had more premature infants(23.2% vs 8.7%,P=0.002),lower birth weight[(3 010.8?852.8) g vs(3 153.2?943.4) g,P=0.026],much longer mean length of hospital stay[(19.0?8.0) d vs(12.2?4.5) d,P=0],more expensive cost[(5 646.4?3632.2) RMB vs(4 175.8?2 879.2) RMB,P=0] and later occurrence day[(21.3?8.6) d vs(15.8?6.0) d,P=0].Compared with simple RSV infection group,mixed infection group had more expensive cost[(6 063.1?3 085.4) RMB vs(4 513.2?3 860.8) RMB,P=0.047] and more oxygen use(40.0% vs 25.7%,P=0.006).The clinical characteristics of patients with RSV pneumonia varied.Preterm group compared with term group more frequently exhibited apnea and cyanosis(20.0% vs 0.7%,42.9% vs 22.7%),respectively.Forty-two percent of them had bacterial infection,while 13.3% of them had infection of other part of body.The prognosis of most RSV(99.0%) infections was good.Conclusions RSV was an important cause of respiratory tract infections during the last five years.Clinical characteristics of RSV infections were atypical.Hospital acquired RSV infection was more severe than the community acquired infection in neonates.There are no specific,effective interventions for treating RSV infections,so preventive measures are most important.
