Objective To explore the relationship between preoperative serum pro-adrenomedullin (pro-ADM) in the patients with closed rupture of small intestine,and postoperative secondary abdominal infection,and to study the value of postoperative serum pro-ADM in assessment of severity of postoperative secondary abdominal infection of this patients.Methods Eighty-five patients with closed rupture of small intestine treated in the emergency surgery from June 2014 to May 2015 were selected.According to the presence of postoperative abdominal infection or not,these patients were divided into infection group and non-infection group.The infection group was further divided into SIRS,sepsis,severe sepsis,septic shock subgroups as per the severity of infection.The levels of serum pro-ADM,interleukin-6 (IL-6),C-reactive protein (CRP) were determined and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was calculated at admission and the first day、the second day and the third day after operation.Comparisons of these biomarkers were carried out to find out the factors associated with postoperative abdominal infection.In addition,ROC curve was used to verify the factors for predicting the abdominal infection of these patients after operation.The relationship between serum levels of pro-ADM and APACHE Ⅱ score after operation was analyzed.The severity of abdominal infection after operation was assessed with laboratory findings.Results Compared with non-infection group,preoperative and postoperative serum pro-ADM (P =0.03,P ＜ 0.01),IL-6 (P =0.02,P ＜0.01) levels and APACHE Ⅱ scores (P ＜ 0.01,P ＜ 0.01) were significantly higher in infection group (P ＜ 0.05).In the infection groups,the postoperative levels of serum pro-ADM and APACHE Ⅱ scores were increased with the severity of infection increased (r =0.924),and the difference between the groups was statistically significant (P ＜ 0.05),but there were no significant differences in IL-6 and CRP levels between two groups.Conclusion (1) The serum levels of pro-ADM before operation has value in predicting the genesis of abdominal infection in these patients after operation.(2) The serum levels of pro-ADM after operation has value in severity assessment of abdominal infection in these patients after operation.

OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.

This research based on the analysis of spontaneous reporting system (SRS) data which the 9 601 case reports of Shuxuening injection adverse drug reactions (ADR) in national adverse drug reaction monitoring center during 2005-2012. Apply to the association rules to analysis of the relationship between Shuxuening injection's ADR and the characteristics of ADR reports were. We found that ADR commonly combination were "nausea + breath + chills + vomiting", "nausea + chills + vomiting + palpitations", and their confidence level were 100%. The ADR and the case reports information commonly combination were "itching, and glucose and sodium chloride Injection, and generally ADR report, and normal dosage", "palpitation, and glucose and sodium chloride injection, and normal dosage, and new report", "chills, and generally ADR report, and normal dosage, and 0.9% sodium chloride injection", and their confidence level were 100% too. The results showed that patients using Shuxuening injection occurred most of ADRs were systemic damage, skin and its accessories damage, digestive system damage, etc. And most of cases were generally and new reports, and patients with normal dosage. The ADR's occurred had little related with solvent. It is showed that the Shuxuening injection occurred of ADR mainly related to drug composition. So Shuxuening injection used in clinical need to closely observation, and focus on the ADR reaction, and to do a good job of drug risk management.

[Objective] To explore whether necroptosis is involved in the mechanism of lung injury induced by intestinal ischemia-reperfusion.[Method] Thirty-two healthy male Sprague-Dawley rats were randomly assigned into 4 groups (n--8):sham operation group (sham group),isehemia/ reperfusion group (I/R group),necroptosis inhibitor necrostatin-1 group (Nec-1 group) and solvent dimethyl sulfoxide (DMSO) group (DMSO group).Model of intestinal I/R injury was produced by clamping the superior mesenteric artery for 1.5 h followed by 6 h reperfusion in rats.Necrostatin-1 1.0 mg/kg was administered 30 min before occlusion in Nec1 group,while the equal volume of DMSO was given instead in DMSO group.The rats were sacrificed at 6 h of reperfusion and the lung tissues were removed for measurement of wet-dry ratio and microscopic examination and scored.The expression of receptor-interacting protein 1 (RIP1) and receptor-interacting protein 3 (RIP3) in lung tissues was detected using Western-blot and immunohistochemistry.[Result] Compared with sham group,lung morphology score and wet/dry ratio in I/R,DMSO group raised (P ＜ 0.05).Lung morphology score and wet/dry ratio statistically declined in Nec-1 group compared with I/R and DMSO group (P ＜ 0.05),while there was no statistical difference of wet/dry ratio between sham group and Nec-1 group (P ＞ 0.05).As the result of westernblot and immunohistochemistry showed,the expression of RIP1 and RIP3 was up-regulated in I/R group and DMSO group (P ＜0.05),which was inhibited by Nec-1 in Nec-1 group (P ＜ 0.05).[Conclusion] Necroptosis is involved in the mechanism of lung injury induced by intestinal ischemia-reperfusion,and Nec-1,the special inhibitor of RIP1,can reduce the injury.

The aim of this study is to investigate the therapeutic effect of RegIII-proinsulin-pBudCE4.1 plasmid on streptozotocin (STZ)-induced type 1 diabetes mellitus and its underlying mechanisms. The model of type 1 diabetes mellitus was established by intraperitoneal injections of STZ (40 mg kg(-1)) to Balb/c mice for five consecutive days. Then, ten type 1 diabetic mice were intramuscularly injected with 100 microg RegIII-proinsulin-pBudCE4.1 plasmid for 4 weeks (one time/week) and the blood glucose levels were monitored every week; whereas another ten diabetic mice served as negative control group were injected with pBudCE4.1 vector at the same dose. Normal control and model control mice were treated with normal saline at identical volume under the same way. Western blotting, MTT assay, ELISA, HE staining and Tunel assay were applied to explore the underlying mechanisms. Results showed that RegIII-proinsulin-pBudCE4.1 plasmid ameliorated the hyperglycemia symptoms in diabetic mouse remarkably. It induced an immunological tolerance state in type 1 diabetic mice by inhibiting the proliferation of splenic lymphocytes and recovering Th1/Th2 balance evidenced by MTT and ELISA analysis. Furthermore, it elevated insulin concentration in the serum of type 1 diabetic mice and promoted the regeneration of beta cells supported by the results of HE staining and Tunel assay. In conclusion, RegIII-proinsulin-pBudCE4.1 plasmid possesses powerful anti-diabetic ability, which may be involved in the inducing of immunological tolerance and enhancing beta cells recovery.
