Objective　To study the effects of systemic irradiation and conglutinant drug W11-a12 on the number and some functions of wound nentrophils (Neu). Methods　Wound Neu was collected from sponges which were implanted in rat's dorsum incision. The number of Neu, as well as the phagocytic function and motility of wound Neu were measured. Results　After 4,6,8 Gy systemic irradiation, the number of white blood cells and Neu in wound, as well as the phagocytic function and chemotactic motility of wound Neu, were significantly decreased at 24 h, 48 h after wounding. W11-a12 markedly increased the number of wound Neu, improved the phagocytic function and chemotactic motility of wound Neu at 24 h, 48 h after wounding despite the rats were radiated or not. Conclusion　The results indicated that the decreased number and function of wound Neu in the early stage of wound healing contributed to the impairment of repair after systemic irradiation. W11-a12 accelerated normal and irradiation-impaired wound healing partly by increasing the number of wound Neu and improving the Neu function.

Purpose To investigate the clinical utility of DAB2IP (DOC-2/DAB2 interactive protein)and β-catenin expression in bladder urothelial carcinoma (BUC).Methods The expression of DAB2IP and β-catenin was detected in 104 BUC cases and 40 peritumorial tissues using EnVision two-step immunohistochemical method,and the association with BUC clinicopathological parameters was analyzed.Results The expression of DAB2IP in BUC was significantly less than that of peritumorial normal tissues,and the expression of β-catenin in BUS was significantly higher than that of peritumorial normal tissues (P ＜ 0.05).DAB2IP expression and histologic grading,clinical pathologic staging and 5 years survival rate had statistical significance (P ＜ 0.05).No statistical significance with gender,age,tumor diameter and in patients with incipient/recurrence.β-catenin expression and age,histologic grading,clinical pathologic staging,tumor diameter and 5 years survival rate have statistical significance (P ＜ 0.05).No statistical significance correlated with gender and in patients with incipient/ recurrence,DAB2IP and β-catenin expression in BUC are negatively correlated (P ＜ 0.05).Conclusion In bladder urothelial carcinoma,down-regulation of DAB2IP and up-regulation of β-catenin,are in a negative correlation.Abnormal expression of DAB2IP and β-catenin is correlated with histologic grading,clinical pathologic staging and prognosis.

Objective To investigate the value of the interhospital transportation and the advantage of the cooperative network to the critically ill children.Methods The clinical data of 232 critically ill chil-dren transported from other hospitals in long distances to PICU of Fudan University Affiliated Children Hos-pital cooperated with Shanghai 120 interprovincial transport Department,between Oct 2010 and Oct 2013, were analyzed retrospectively.Results At otal of 232 critically ill childrne were transported from 31 hospi-tals of Eastern China region including five provinces and the city of Shanghai.Among thse e critically ill chil-dren 141 casse were male and 91 cases were femla e,with age from 29 days ot 13 years( median age was 12 months) and weight from 2.5 to 66 kg ( median weight was 10 kg ) .The average pediatric clinical illness score was 80.4 ±7.7,155 cases(66.8%) were single organ dysfunction,55 cases(23.7%) were multiple organs dysfunction,105 cases(45.3%) were mechanical ventilation required fort ransportait on.Referral radi-us was 50-1 000 km(median).Among these patients,87 cases(37.3%) weret ransported over 200 km radius and73 cases(36%) were transop rted 101-200 km,62 cases(26.7%) were transported 100 km or less.D ur-ing the transportation,0 case died,3 cases(1.3%) received cardiopulmonary resuscitation treatment,2 cases (0.9%) received electrical conversion treatment,2 cases(0.9%) were replaced endotracheal intuab tion,the success rate of transportation was 100%.The top 4 disae ses were respiratro y id seases(90 cases,38.8%), neural diseases(43 cases,18.5%) ,cardiovascular diseases(36 cases,15.5%) and acute pediatric trauma(28 cases,12.1%) .Al l 232 cir tically ill children were admitted to our PICU for further treatment through the Green Channel.In the end, 178 cases ( 76.7%) discharged, 24 cases ( 10.3%) gave up and 32 cases (13.8%) died.Among thse e 232 rc itically ill children,30 cases(12.9%) received special organ replacement treatment,4 casse ( 1.7%) of whom were treated with extracorporeal membrane oxyg enation, 26 cases (11.1%) received blood purification therapy.Conclusion Establishing the system of transportation between PICU of hospitals will be propitious to treat the critically ill children energetically and effectively.It is worth pro-moting to master the transportation indication of children with critical illness,which is safe and reliable.

Objective:To analyze and optimize the extraction technology of Geum aleppicum by Box-Behnken design and response surface methodology. Methods:With the content of total flavonoids as the index, the effects of three factors including the solvent-solid ratio, ethanol concentration and extraction time on the content of total flavonoids were studied by single factor experiment, and the ex-traction technology was optimized by Box-Behnken design and response surface methodology. Results: The optimal extraction condi-tions of Geum aleppicum were as follows:the solvent-solid ratio was 4. 2, the ethanol concentration was 50% and the extraction time was 80 min. Under the above conditions, the average yield was 12. 590 0 mg·g-1 . Conclusion: Optimizing extraction technology of the total flavonoids in Geum aleppicum by Box-Behnken design and response surface methodology is reasonable, and the mathematical mod-el is consistent with the experimental data, which has good predictability.

ObjectiveTo investigate the incidence and risk factors of antibiotic-associated diarrhea (AAD) of pediatric patients with severe bacterial pneumonia.MethodsClinical data of 1086 pediatric patients with severe bacterial pneumonia from January 2010 through January 2014 were recruited. The incidence and risk factors of AAD were retrospectively analyzed. ResultsThe incidence of AAD in 1086 pediatric patients with severe bacterial pneumonia was 36.74%. The incidence of AAD in patients younger than 2 years old were higher than that in those older than 2 years, once or more times of mechanical venti-lation history were higher than that with no arrangements of this treatment, administering of combined antibiotics therapy were higher than that with single antibiotics, and the incidence of AAD due to amoxicillin/clavulanate, piperacillin/tazobactam, cefo- perazone/sulbactam in pediatric patients were 43.55%, 43.75%, and 45.03%, respectively. Three β-lactam/β-lactamase inhibitors above were risk factors of AAD through multivariate Logistic regression analysis.ConclusionThe high incidence of AAD in pediatric patients with severe bacterial pneumonia was associated with some risk factors, including younger than 2 years old, me-chanical ventilation, combined antibiotics therapy and administration of β-lactam/β-lactamase inhibitor (amoxicillin/clavulanate, piperacillin/tazobactam, cefoperazone/sulbactam).

(P > 0. 05). Conclusions:Metronidazole-containing triple therapy may reduce the CD infection secondary to eradication of Hp infection in pediatric patients,and has no negative impact on efficacy of Hp eradication.
