Purpose To investigate the expression of Netrin-1 in ovarian serous carcinoma and its c1inicopatho1ogica1 significance. Methods Netrin-1 protein expression was assessed by immunohistochemica1 method in tissue specimens from 20 cases of benign ovari-an serous cystadenomas,13 cases of border1ine ovarian serous neop1asms and 32 cases of ovarian serous carcinomas( OSC). Results The positive proportion of Netrin-1 protein in OSC tissues was significant1y higher than those in border1ine and benign ovarian serous ne-op1asms(P<0. 01). The expression of Netrin-1 in OSC tissues was associated with tumor grade and c1inica1 stage(P<0. 05),but not associated with age,site,tumor size or 1ymph node metastasis( P>0. 05). Kap1an-Meier ana1ysis showed that the 5-year surviva1 rate of patients with Netrin-1 over-expression was significant1y 1ower than that of patients with 1ower expression( P<0. 05 ). Conclu-sions The high expression of Netrin-1 in OSC tissues indicates that Netrin-1 p1ays an important ro1e in cancer pathogenesis and deve1-opment and it may be a new assistant marker for prognosis of OSC.

Objective To investigate instant messenger management on moderate asthma control in young and middle-aged patients.Methods Sixty young and middle-aged asthma patients enrolled were divided into 2 groups by random number table,traditional management group (group A) and messenger management group (group B),and received the asthma treatment with traditional management or messenger management for 1 year.The compliance,control condition,pulmonary function and Saint George respiratory questionnaire(SGRQ) were compared between two groups.Results After one year management,there were 20 patients in proceeding of the standard treatment,15 total control,10 partial control and 5 uncontrolled in group A,while there were 26 patients in proceeding of the standard treatment,21 total control,7 partial control and 2 uncontrolled in group B.Compared with group A,the treatment adherence(x2 =6.331,P ＜ 0.05),satisfaction degree (t =6.051,P ＜ 0.01),asthma control rate (x2 =6.490,P ＜ 0.05),efficacy satisfaction (t =6.051,P ＜ 0.01) were all increased in group B.Forced expiratory volume in 1 second was elevated more significantly in group B than that in group A [(0.132 ± 0.175) L vs.(0.326 ± 0.125) L] (t =5.099,P＜ 0.01).SGRQ scores were decreased more obviously in group B than that in group A (t =4.316,P ＜ 0.01).Conclusions The asthma control,respiratory and pulmonary function can be improved by messenger management in young and middle-aged patients.So promoting the messenger management model actively is advantageous to improve the level of prevention and treatment of asthma in China.

Objective: To explore the relevant factors of acquired swallowing disorders in adult patients after cardiac surgery. Methods: A Jiatian water swallowing screening test was conducted for adult patients after cardiac surgery in our hospital from 2015-03 to 2015-09. There were 32 patients with acquired swallowing disorder deifned as Case group and meanwhile 420 patients without swallowing disorder at the same word deifned as Control group. Non-conditional Logistic regression analysis was applied to study the relevant factors for acquired swallowing disorders. Results: The overall incidence of acquired swallowing disorders was 7.08%. Multi Logistic regression analysis presented that duration of endotracheal intubation (OR=1.060,P<0.001), pre-operative arrhythmia (OR=2.780,P=0.019), NYHA grade (OR=1.789, P=0.033) and Euroscore (OR=1.216,P=0.040) were the relevant factors for the occurrence of acquired swallowing disorders in adult patients after cardiac surgery. Conclusion: Medical professionals should pay special attention to patients with above mentioned risk features at post-operative drinking to reduce the complications of acquired swallowing disorders.

Objective To evaluate the effect of fluid load on the prognosis of severe hand , foot and mouth disease in children. Methods The patients with severe hand foot and mouth disease in the emergency department of PICU in our hospital were enrolled as the research object. We would collect demographic characteristics , labora-tory tests and clinical data: age, gender, focus, basic disease, and simplified acute severity score (SAPS)Ⅱ and record the cumulative amount of fluid balance at 24, 48, 72 hours after admission. Results There was a signifi-cant difference on fluid balance at 48 and 72 hours between the survival group and the death group , the death group appeared the positive liquid balance , and there were significant differences in PICU retention time , mechani-cal ventilation rate, MODF involved organs, mortality and other prognostic indicators between the negative fluid balance group and the positive fluid balance group. Conclusion Fluid balance is an important treatment for severe hand foot and mouth disease, and positive liquid balance is related to mortality and other adverse prognosis.

Objective To investigate the effect of inhalation of hydrogen (H2) on the inflammation response during sepsis-induced acute lung injury in mice.Methods Forty-eight male ICR mice,aged 5 weeks,weighing 20-25 g,were randomly divided into 4 groups (n =12 each):sham operation group (group A),sham operation + H2 group (group B),sepsis group (group C) and sepsis + H2 group (group D).Sepsis was produced by cecal ligation and puncture (CLP).Groups B and D received 1 h inhalation of 2 ％ H2 at 1 and 6 h after CLP or sham operation.The behavior was assessed and scored at 24 h after CLP.Arterial blood samples were taken for blood gas analysis.Oxygenation index was calculated.Venous blood samples were taken for determination of the levels of serum tumor necrosis factor-α (TNF-α),interleukin-1 (IL-1β),high mobility group protein B1 (HMGB1) and interleukin-10 (IL-10).The mice were then sacrificed and lungs were removed for determination of the levels of TNF-α,IL-1β,HMGB1 and IL-10 in lung tissues.The apoptotic index was calculated.Results Compared with group A,the behavior score,apoptotic index and levels of TNF-α,IL-1β,HMGB1 and IL-10 were increased,and the oxygenation index was decreased in groups C and D,and no significant change was found in the parameters mentioned above in group B.Compare with group C,the oxygenation index and level of IL-10 were significantly increased,and the behavior score,apoptotic index and levels of TNF-α,IL-1β and HMGB1 were significantly decreased in group D.Conclusion Inhalation of H2 can regulate the balance between pro-and anti-inflammatory cytokines,inhibit the inflammation response and alleviate sepsis-induced acute lung injury in mice.

OBJECTIVE To discuss the preventive methods of hepatitis B virus reinfection after liver transplantation. METHODS Eighty eight liver transplantation recipients with HBV-related end-stage liver diseases including chronic fulminant hepatitis B,end-stage liver cirrhosis and liver carcinoma were analyzed retrospectively,and were given lamivudine pre-transplantation to prevent hepatitis B virus reinfection.Post-transplantation medicines of lamivudine were administered in 3 cases;lamivudine and hepatitis B immunoglobulin(HBIg) in 85 cases.The follow-up criteria included serum HBV,HBV-DNA,liver biopsy,immunohistochemical study of liver biopsy specimens and clinical manifestations.All of patients were followed-up 6 months at least.RESULTS Two of the three cases who taken lamivudine developed reinfection,the little time is 6 months following liver transplantation.There were three of eighty five cases taken lamicudine and HBIg(small dosage) developed reinfection.CONCLUSIONS Liver transplantation is an effective treatment for HBV-related end-stage liver diseases.Given lamivudine at the pre-transplantation could reduce the levels of the HBV virus copies.Lamivudine and HBIg post-transplantation offer effective prevention against hepatitis B virus reinfection.

Objective Follow-up monitoring was carried out in infants infected with cytomegalovirus (CMV) so as to find out whether breastfeeding could bring about changes of CMV viral load.Methods Saliva of the neonates born in Changzhou Maternal and Child Health Hospital from Nov.2010 to Feb.2012,was collected for CMV screening.Premature infants,or the infants with seriously infectious diseases and deformities were excluded,such as severe intrauterine infection,congenital immune deficiency disease and so on.The full-term infants with aymptomatic infection were divided into the artificial feeding group and the breastfeeding group,and followed up for 6 months.During the 1st,the 3rd and the 6th month after their birth,their saliva and their mother's breast milk were collected.The method of realtime fluorescent quantitative PCR was adopted to test the changes in the viral load of CMV-DNA in the saliva and breast milk.Meanwhile,head B-ultrasound test,otoacoustic emission hearing screening,liver function test,blood routine analysis and so on were performed.Results Among infants from both artificial feeding group and breastfeeding group,during the 1 st,the 3 rd and the 6th month after birth,no significant changes in the DNA viral load of saliva and breast milk cytomegalovirus were found (t =2.832,3.161,3.475,all P ＞ 0.05).And in breastfeeding group,the cytomegalovirus DNA viral load in breast milk were 3.125 × 103 ±2.017 × 102 (the 1st month),2.688 × 103 ±2.251 × 102 (the 3rd month),3.016 × 103 ±2.613 × 102 (the 6th rmonth),also no significance during the time (F =1.725,P =0.667).Meanwhile,the head B-ultrasound,otoacoustic emission hearing screening,liver function test,blood routine analysis,etc showed no clinical significance (F =1.725,P =0.667).Conclusions In the CMV-infected neonates,even if CMV in breast milk is tested to be positive,breastfeeding can continue without causing secondary symptoms of infection.

Objective:To investigate the association between the single nucleotide polymorphisms(SNPs) of transporter associated with interleukin2(IL-2),interleukin4(IL-4)and the susceptibility of hepatitis B in north China.Methods:Genomic DNA was extracted from the peripheral blood leukocytes of hepatitis B patients and healthy controls.Two fragments covering -330 of the IL-2 gene and -590 of the IL-4 gene were amplified by polymerase chain reaction (PCR).The SNPs were revealed by restriction fragment length polymorphism (RELP).Software PHASE 1.0was used to construct the haplotype of every individual.Unconditional Logitic regression model was used to analyze the statistical association of genotype or haplotype in two groups adjusted by gender and age.Results:There was significant difference in the SNPs of IL2 between the healthy controls and the heptitis B patients in north China.Significant difference was also found in the combination of --/GT to the two groups.Conclusion:SNPs of IL2(-330) may have relation to the susceptibility o heptitis B.--/GT was also related to the susceptibility of heptitis B.These findings suggest that SNPs of IL2 is one of the important host factors to the infection of the heptitis B.
