Objective To investigate the imaging characteristics of primary abdominal cocoon in order to improve diagnosis level.Methods The imaging data of 5 cases of primary abdominal cocoon proved by surgery and pathology were retrospectively analyzed.Results Abdominal plain X-ray suggested intestinal obstruction in 3 out of 5 cases.The gastrointestinal barium meal showed cauliflower signal in all 5 cases;CT suggested a conglomeration of multiple small bowel loops in the 5 cases and the intestinal loops seemed to be encapsulated in a thickened capsule.Conclusion Abdominal cocoon should be taken into consideration when gastrointestinal barium meal shows cauli flower signal and CT displays conglomeration.

Objective To explore the diagnostic value of multislice spiral CT enterography(MSCTE) in patients with primary tumors of the small intestine.Methods Clinical data of 40 patients with primary tumors of the small intestine from Jan.2011 to Dec.2013 were analyzed.All patients were underwent MSCTE examination.Analyzed the coincidence rate between diagnostic results and pathological diagnosis.Results Pathological diagnosis of all patients showed that 15 cases were with small intestinal stromal tumors,10 cases with primary intestinal adenocarcinoma,9 cases with intestinal lymphoma and 6 cases with leiomyoma.The diagnoses of MSCTE were as follows:Twelve cases were with gastro intestinalstromaltumors,10 cases with primary intestinal adenocarcinoma,9 cases with intestinal lymphoma and 9 cases with leiomyoma.Consistency test(Kappa test) results showed that there was a good consistency between two dignosis methods(Kappa values =0.71).The coincidence rate of MSCTE in the diagnosis of primary tumors of the small intestine was 92.5％.Conclusion MSCTE is a convenient and safe method with high degree of accuracy,which provides a broad prospect for the diagnosis of primary tumors of the small intestine.

Objective To evaluate the effect of comprehensive intervention measures on preventing and controlling surgical site infection (SSI)in patients undergoing total abdominal hysterectomy.Methods Patients undergoing total abdominal hysterectomy in a hospital between January 2011 and December 2014 were investigated retrospec-tively,patients in 2011 were as control group,from January 2012,a prospective monitoring on SSI was initiated, comprehensive intervention measures were taken,patients between January 2012 and December 2014 were as inter-vention group,SSI before and after the intervention was compared.Results A total of 1 052 patients undergoing to-tal abdominal hysterectomy were investigated,267 cases were monitored before intervention,25 patients (9.36%) developed healthcare-associated infection (HAI),12(4.49%)of whom were with SSI;785 cases were monitored af-ter intervention,13 (1 .66%)of whom were with SSI,incidence of SSI in 2012,2013,and 2014 were 2.31 %, 1 .89%,and 0.77% respectively,there was a decreasing tendency(χ2 =7.30,P <0.01 ).Conclusion Prospective monitoring on SSI and comprehensive intervention can reduce the incidence of SSI in patients undergoing total abdominal hysterectomy.

Objective To investigate the changes of plasma vascular endothelial growth factor( VEGF) of patients of advanced primary liver cancer before and after interventional treatment and its clinical Significance. Methods Forty-six patients with advanced primary liver cancer were performed the hepatic arterial chemoembolization and served as observation group. Sixty healthy people were served as control group and measured their level of serum VEGF. The level of serum VEGF of patients in observation group before treatment and intervention 1 month were measured. Results Before interventional treatment,the serum VEGF level of observation group were(510. 0 ± 310. 0)ng/L,significantly higher than that of control group((27. 0 ± 23. 0) ng/L,P﹤0. 001). After interventional treatment,he serum VEGF level decreased to(316. 4 ± 240. 7)ng/L and the difference was statistically significant( P=0. 036 ). After one month interventional treatment,4 cases were complete remission(8. 70%),34 cases were partial remission(73. 91%),6 cases were in stable(13. 04%),and 2 cases were progress( 4. 35%),and the total effective rate were 82. 61%( 38/46 ). The 38 cases who were complete remission and partial remission were been served as effective group,the other 8 cases were served as invalid group. The serum VEGF level in effective group were( 260. 6 ± 70. 5 )ng/L,lower than that in invalid group(( 346. 7 ± 61. 3 )ng/L,P = 0. 046 ). Conclusion Hepatic arterial chemoembolization treatment on primary liver cancer curative effect is a better approach. VEGF involves in the development of primary liver cancer,and the high serum VEGF level with poor prognosis can be the reference of efficacy.

Myasthenia gravis is an autoimmune disorder resulting from the production of antibodies against acetylcholine receptors leading to the destruction of the postsynaptic membrane at the neuromuscular junction.Myasthenic crisis is defined as any myasthenia gravis exacerbation necessitating mechanical ventila-tion or post-operation extubation delayed beyond 24 hours because of respiratory weakness.Most patients presenting with myasthenic crisis have an identifiable risk factor.The diagnosis of myasthenic crisis should be suspected in all patients with respiratory failure,particularly those with unclear etiology.Acute management of myasthenic crisis includes ventilatory therapy,removal of the offending trigger and immunomodulatory treat-ments.The latter includes plasma exchange or intravenous immunoglobulin,and high dose corticosteroids therapy.

Acute kidney injury(AKI) is defined as functional and structural disorder or signs of renal damage including any defect from blood and urine test,or tissue imaging that is less than 3 months.The current treatment for AKI includes therapeutic agents and renal replacement therapy (RRT).The goal of RRT is to remove endogenous and exogenous toxins,inflammatory mediator,pathogenic factor,and to maintain fluid,electrolyte,and acid-base balance until renal function returns.The principal methods of RRT include intermittent hemodialysis,continuous renal replacement therapy,peritoneal dialysis,plasmaphresis exchange and hemoperfusion.In this article,we discussed the timing,choice of therapeutic mode,indication and common technical issues of RRT in pediatric AKI.

Interleukin-10 (IL-10) is an immuno-regulatory cytokine,which is well known for its immunosuppressive function.IL-1O can act on a variety of immune cell subsets and play an immunosuppressive effect through a variety of ways.It plays an important role in the tumor immune escape.Recent studies show that IL-10 also has an immune-stimulating function,which is presumably a pluripotent cytokine.This paper will combine the latest literature to summary the positive and negative regulatory roles of IL-10,mediation ways in the tumor and the relationships with prognosis.

Neovascularization is the main cause of blindness, such as diabetic retinopathy, retinopathy of prematurity and age - related macular degeneration. Vascular endothelial growth factor( VEGF) plays an important role in the formation of angiogenesis, and is considered to be the most potent angiogenic growth factor. Placental Growth Factor(PlGF) is one of the VEGF family, which play a crucial role in endothelial cell proliferation and migration, angiogenesis, and immune - mediated inflammation. Meanwhile, PlGF is specifically expressed in pathological angiogenesis, but not in normal blood vessels. In recent years, there has been increasing attention to PlGF, therefore this article reviews the role of PlGF in neovascular ocular diseases.
