Objective To investigate the clinical value of the duodenum double lumen cannula suction in duodenal rupture repair.Methods According to the operation methods,60 patients with duodenal rupture undergoing duodenal repair were divided into the surgical drainage alone group(26 cases)and double sets attract tube group (34 cases).The surgery effect and complications were observed.Results The difference of traffic flow 7 days after the operation between the two groups was statistically significant(t =7.564,P <0.05).The length of stay and hospital costs of the surgical drainage alone group were more than those of the double sets attract tube group,the differences were statistically significant(t =3.567,4.123,all P <0.05).The fistula,intra -abdominal infections,wound infec-tions,pulmonary infection rates of the surgical drainage alone group were 30.77%,42.31%,46.15%,26.92%, which were higher than 2.94%,11.76%,8.82%,2.94%,5.88% of the double sets attract tube group,the differ-ences were statistically significant(χ2 =8.949,7.330,10.950,2.986,5.116,all P <0.05).Conclusion Applica-tion of the double lumen cannula duodenal suction in duodenal rupture repair can significantly reduce the incidence of postoperative complications,has certain security,it is recommended in clinical practice.

Sepsis is an organ dysfunction syndrome caused by an abnormal host immune response because of infection. Pyroptosis is a newly discovered programmed cell death relies on caspase-1, caspase-11, caspase-4, caspase-5 and is characterized by the release of inflammatory cytokines interleukin-1β (IL-1β) and IL-18. The exploration of the molecular mechanisms of pyroptosis and the correlation between pyroptosis and sepsis can provide new ideas and new targets for the treatment of sepsis.

Objective To explore the clinical effect and toxicity of daunorubicin combined with cytarabine (DA regimen) and idarubicin combined with cytarabine (IA regimen) for the treatment of patients with acute myeloid leukemia (AML) as induction chemotherapy. Methods The clinical data of 84 newly diagnosed AML patients (except M3) treated with DA or IA regimen were analyzed retrospectively. DA regimen group included 32 patients (17 males and 15 females with median age of 46 years), while IA regimen group included 52 patients (29 males and 23 females with media age of 49 years). Efficacy index was complete remission (CR), total efficiency and adverse reactions after one course of chemotherapy rate. Results In DA regimen group,the CR rate was 65.6 %(21/32), and the total efficiency rate was 75.0 %(24/32), while in IA regimen group, the CR rate was 71.2 %(31/52), and the total efficiency rate was 80.8 %(42/52), respectively, but, the differences of media survival and 5-year survival rate were not statistically significant (16.8 months vs. 24.9 months, 26 % vs. 44 %, both P>0.05). The main side effect in the two groups included hematologic (bone marrow suppression) and non-hematologic adverse reactions, with no significant difference between the two groups (all P>0.05). Conclusion For newly diagnosed AML patients, remission rate and total efficiency of DA regimen are same as IA regimen after one course treatment, and adverse events between the two regimens do not differ significantly.

To investigate the protective effect of interleukin-5 (IL-5) in septic mice,male C57BL/6 mice were divided into three groups including sepsis group with intraperitoneal injection of lipopolysaccharide (LPS,20 mg/kg),study group with combined IL-5 (1 μg per mouse) and LPS (20 mg/kg),control group with normal saline.Pathological changes were tested including lung,heart and kidney tissues.The serum cardiac troponin I (cTnI),serum creatinine (SCr),blood urea nitrogen (BUN),tumor necrosis factor α (TNFα),IL-6,IL-1β,and the chemokine (C-X-C motif) ligand 1(CXCL1) were measured and the survival at 7 d after treatment were recorded.Compared with sepsis group,tissue damages of lung,heart and kidney in IL-5 intervention group were ameliorated.The cTnI,SCr,BUN levels in study group were significantly decreased at 24 h (P＜0.05).In addition,TNFα was significantly decreased at 3 h (P＜0.05),and CXCL1 decreased at 12 h (P＜0.05),while IL-6 and IL-1β were similar at each time point (P＞0.05).The mortality at 7 d was less in IL-5 treatment group.In summary,IL-5 has a protective effect and reduces the inflammatory response in septic mice.

Objective: To evaluate the safety of enterovirus 71（EV71）inactivated vaccines produced by Wuhan Institute of Bio Products through learning the incidence of adverse events following immunization（AEFI）in children aged 6 months to 3 years old after vaccination. Methods: According to the national requirement for vaccine safety monitoring program，data of AEFI cases after inoculated EV71 vaccines from September 2017 to October 2018 in Zhejiang Province was collected by combining active and passive monitoring. Demographic characteristics，space distribution，dose and incidence of AEFI were analyzed. Results: A total of 107 503 children were included in this study，of which 27 173 were actively monitored and 80 330 were passively monitored. The monitoring results showed that 288 cases of AEFI occurred after inoculated EV71 vaccines，the reported incidence rate was 267.90/100 000. Of 288 cases，266 cases had common reactions（247.43/100 000），14 cases had abnormal reactions（13.02/100 000）and 8 cases had complications（7.44/100 000）；145 cases were passively monitored（180.51/100 000）and 143 cases were actively monitored（526.26/100 000）；150 cases were males and 138 cases were females，with the males to females ratio of 1.09∶1. The AEFI of EV71 vaccines were reported in all the cities of Zhejiang Province，with Jinhua，Taizhou and Hangzhou ranking the top three and accounting for 50.69% of all the reported cases. About 202 cases of AEFI（70.14%）occurred after the first dose of EV71 vaccines，and 163 cases（56.60%）occurred on the day of inoculation.Most of common reactions were fever，swelling and sclerosis. The harm of the reported abnormal reactions was mild，with 8 cases of anaphylactic rash and no other serious abnormal reactions were found. Conclusion The reported incidence rate of AEFI of the domestic EV71 vaccine in children aged from 6 months to 3 years is 267.90/100 000，without serious abnormal reactions，suggesting that the EV71 vaccine is safe.

Objective: To analyze the strengths, weaknesses, opportunities and threats of the construction on intelligent vaccination clinics in Zhejiang Province, so as to provide countermeasures for promoting the construction of intelligent vaccination clinics in Zhejiang Province. Methods: By reviewing the annual reports of Zhejiang immunization planning, survey data from Zhejiang Centers for Disease Control and Prevention and Immunization Intelligent Service System, data of human resources of immunization planning, vaccine procurement, construction progress of intelligent vaccination clinics and vaccination were collected. The relevant literature was searched to gather information on the construction standards and norms of intelligent vaccination clinics. The analysis of the strengths, weaknesses, opportunities and threats (SWOT) of the construction of intelligent vaccination clinics was conducted, and corresponding countermeasures and suggestions were proposed. Results: The National Immunization Program reported vaccine rate in Zhejiang Province is more than 99%, and standardized vaccination clinics have been popularized throughout the province. The vaccination staff are professional, and a province-wide intelligent immunization service information system has been established, providing the resources and conditions for the construction of intelligent vaccination clinics. However, there are problems such as low data quality and matching efficiency in vaccination, insufficient data interoperability and sharing, unbalanced regional capabilities in intelligent transformation, and uneven distribution of talent and resources. It is crucial to seize the opportunities presented by the development of big data and artificial intelligence, rely on the regional development of the Internet and health industry, seize the opportunity of rapid growth in demand for intelligent vaccination services and high public acceptance, accelerate the construction of intelligent vaccination clinics, and establish intelligent vaccination service standards as soon as possible. Conclusion We should seize the opportunities presented by the digital reform and development, fully utilize the existing vaccination resources and strengths, address the shortcomings, and accelerate the construction of intelligent vaccination clinics in Zhejiang Province.

OBJECTIVETo observe the immune reaction in the mixed culture of host lymphocytes with allogenic and host endothelial cells.

METHODSThe host epithelial cells and lymphocytes from burn patients and allogenic epithelial cells were mix-cultured in different ratios, so as to simulate the local immune micro-environment of host skin island in intermingled skin grafting. In addition, the cells from normal human subjects were also mix-cultured as control. The lymphocyte cpm values were detected by (3)H-TdR and HLA molecules and T cell subgroup were determined by immunohistological technique.

RESULTS(1) The lymphocyte proliferation reaction could be effectively inhibited by the epithelial cells from burn patients but not from normal control. (2) The inhibition of host lymphocyte proliferation could not be mediated by the HLA-DQ molecules of epithelium from burn patients. (3) The positive expression rate of HLA-DR of epithelia from burn patients was evidently higher that that from normal control (P < 0.05), (4) The CD8 expression of lymphocyte in burn patients was significantly higher than that in normal control (P < 0.01), while the CD4 expression in burn patients was lower than that in normal control (P < 0.01). But there was no obvious difference of the CD3 expression between patients and normal subjects (P > 0.05).

CONCLUSIONThe lymphocyte proliferation reaction could be obviously inhibited by the host epithelium, which might be related to the specific immune state of the host lymphocytes and epithelium of burn patients.
