Objective To investigate the effects of different flow volume of continuous 1:1 blood crystalloid cardioplegia on open heart surgery.Methods Retrospective randomized study was performed on 80 patients undergoing valve replacement and congenital heart disease with 1:1 blood crystalloid cardioplegia by minimum-flow continuous perfusion[0.5ml/(kg·min),group A,40 cases],high-flow continuous perfusion[(2.0 ml/(kg·min),group B,40 cases).The changes of creatine kinase(CK),isoenzyme of creatine kinase(CK-MB),lactate dehydrogenase(LDH),lactic dehydrogenase isoenzyme(LDH_1)were detected before operation and at 6,12,24,48,72 h after operation.Results The cardioplegia liquid was (41.72±7.98)ml/kg in group A,(142.09±9.65)ml/kg in group B,there was significant difference between two groups(P<0.05).During the first 72 h postoperative the value of CK,CK-MB,LDH and LDH1 in two groups were increased to different degree,serum enzymes levd increased significantly between 12,24 h after operation(P<0.05)and return to normal at 72h after operation in two groups.Butbetween two groups there was no significant difference(P＞0.05).ConclusionMinimum-flow continuous perfusion of 1:1 blood crystalloid cardioplegia appears to be superior in safety,decrease of myocardial enzymes integrity.

Acute kidney injury (AKI) is the most common and serious complication in the intensive care unit.The mortality of AKI is still as high as 60％ in critically ill children because of lack sensitive and special early predictive biomarker.Neutrophil gelatinase-associated lipocalin is one of the most promising early diagnose and predict biomarkers for AKI,produced and secreted by kidney tubule cells at low levels,but increasing dramatically in the urine and serum after ischemic, sepsis, or nephrotoxic injury of the kidneys.This review is to summarize the role of neutrophil gelatinase-associated lipocalin as an early biomarker of AKI with different clinical settings in children.

Diffuse large B-cell lymphoma (DLBCL) is the aggressive non-Hodgkin's lymphoma.Rituximab in combination with chemotherapy had improved the outcomes,however,a substantial proportion of these patients transfer into refractory or eventually relapsed lymphoma after using R-CHOP as a front-line treatment regimen with poor prognosis.With the research development on DLBCL and its related gene,it is confirmed that gene biological targeted therapy can improve the prognosis of patients with refractory /relapsed DLBCL (RR-DLBCL).Recently,some new targeted therapies become research hotspots.This review will focus on recent development and future direction of biological targeted treatment in RR-DLBCL.

Objective To explore the effect of cognitive therapy on patients with traumatic paraplegia.Methods Toally 100 traumatic paraplegia patients were randomly divided into observation group and control group with 50 cases in each.The control group received routine nursing intervention and the observation group cognitive therapy on the basis of intervention for the control group.The two groups were compared in terms of anxiety,depression,mental health,suicidal ideation and quality of life by the instruments of self-rating anxiety scale (SAS),self-rating depression scale (SDS) and suicide attitude questionnaire (SQA) before and after intervention.Results Before the intervention,the scores by SDS,SAS scores and SQA were insignificant different between the groups (P＞0.05).Mter the intervention,the scores on suicidal ideation in the observation group were significantly higher and the quality of life were significantly higher and the depresion and anxiety and the mental health status were lower than those of the control group (P ＜0.05).Conclusion The cognitive therapy for the patients with traumatic paraplegia can significantly alleviate their depression and anxiety,reduce their suicidal ideation and improve the quality of life.

Atherosclerosis is the pathological basis of ischemic stroke. Peripheral blood leukocytes are involved in the occurrence and progression of atherosclerosis and cause vascular endothelial injury. A series of changes of peripheral immune cel take place after acute ischemic stroke and cause inflammatory cel infiltrating into the brain tissue. The elevated leukocyte count is closely associated with the occurrence and prognosis of coronary atherosclerotic heart disease. Studies have also shown that the elevated leukocyte count may influence the occurrence of ischemic stroke, neurological deficit, recurrence, and death. This article reviews the relationship between peripheral blood leukocytes and ischemic stroke.

Objective To evaluate the clinical value of the immunochemistry staining of thyroid transcription factor-1 (TTF-1), cytokeratin7 (CK7), P63, and cytokeratin5/6 (CK5/6) in the bronchoscop-ic forceps biopsy specimen in the differential diagnosis of non-small cell lung cancers.Methods Totally 143 cases of non-small cell lung cancers from Department of Respiratory and Department of Oncology from Nov 2012 to Jan 2014 were diagnosed with pathological examinations of the bronchoscopic forceps biospy.The sen-sitivity and specificity of TTF-1, CK7, P63, and CK5/6 of forceps biopsy at the diagnosis of lung adenocarci-noma and squamous cell carcinoma were calculated.Results The expressions of TTF-1 and CK7 in the pul-monary adenocarcinomas were higher than the pulmonary squamous cell cancer ( P <0.01).The diagnosis sensitivity and specificity of TTF-1 in the pulmonary adenocarcinoma were 85.1%(63/74) and 98.6%(68/69), respectively.The diagnosis sensitivity and specificity of CK7 in the pulmonary adenocarcinoma were 82.4%(61/74) and 91.3%(63/69), respectively.The diagnosis sensitivity and specificity of P63 in the pulmonary squamous cell cancer were 97.1% ( 67/69 ) and 89.2% ( 66/74 ) , respectively.The diagnosis sensitivity and specificity of CK5/6 in the pulmonary squamous cell cancer were 79.7%(55/69) and 89.2%(66/74), respectively.The combined expression of CK7(+)/TTF-1(+) in the pulmonary adenocarcinoma was higher than the pulmonary squamous cell cancer ( P <0.01).The combined expression of P63(+)/CK5/6(+) in the pulmonary squamous cell cancer was higher than the pulmonary adenocarcinoma ( P <0.01).Conclusions The combination use of the immunochemistry staining of TTF-1, CK7, P63, and CK5/6 helps to differentiate lung adenocarcinoma and squamous cell cancer.

The infrapopliteal arteriosclerosis occlusive disease mainly involves the anterior tibial artery,posterior tibial artery and fibular artery.For the arteriosclerosis occlusive disease of larger arteries of lower extremity,such as iliac artery,femoral artery,etc.,the interventional therapy pattern has been already very mature.However,as the infrapopliteal artery is fine in diameter and the lesion is usually wide with extensive calcification,it is hard to effectively treat the infrapopliteal arteriosclerosis occlusive disease with routine interventional therapy.The therapeutic methods of infrapopliteal arteriosclerosis occlusive disease mainly include surgical treatment,endovascular treatment,drug therapy,and the autologous stem cell transplantation therapy that is still in the research stage at present.This paper aims to introduce the latest progress in interventional therapy for the treatment of infrapopliteal arteriosclerosis occlusive disease in recent years,and to make a prospect for clinical practice in future.

Objective To explore the microsurgical skills and clinical value of transorbitozygomatic approach for cavernous sinus tumors. Methods A retrospective research was given to 19 patients with cavernous sinus tumors microsurgically treated by transorbitozygomatic approach.Their tumors pathological types,clinic symptoms,characteristic images,surgical approach,surgical skills and postoperative complications were systemically analyzed. Results Total removal of the tumor was achieved in 17 cases and subtotal removal in 2 cases.38 percent of cranial nerves deficit was improved,43 percent of cranial nerves symptoms did not change,and 19 percent of cranial nerves palsies worsened.New cranial nerves symptoms occurred in 5 cases.No other severe complications or death occurred in all cases. Conclusion Transorbitozygomatic approach can preferably expose and totally resect cavernous sinus tumors.Knowing macro-micro anatomy of this approach,understanding the pathological-anatomic relationships betweem tumor and cavernous sinus,having practiced microsurgical skills are the linchpins to resect the tumor totally and protect cranial nerves effectivctively.

Objective:To investigate costimulatory molecules and adhension molecules in the pathogenesis of experimental colitis in rats.Methods:Models of experimental colitis were established by enema with trinitrobenzenesulphonic acid. Prednisolone or salicylazosulfapyridine was given as treatment.Nomal rat and untreated colitis rat groups were set up as controls.Histological scoring was performed.Expression of CD11b,CD28 and CTLA-4 were detected by flow cytometry in peripheral blood,spleen and intraepithelial mononuclear cells of colon.Results:Expressions of CD11b,CD28 and CTLA-4 were high in experimental colitis. CD11b and CD28 decreseased after treatment of prednisolone or salicylazosulfapyridine,while CTLA-4 increased further,which were significant statistically.Conclusion:Adhesion molecules may have a role in the pathogenesis of experimental colitis.The dysregulation of CD28 and CTLA-4 may be one of the mechanisms in IBD.The mechanisms of prednisolone and salicylazosulfapyridine may be associated with costimulatory molecules and adhension molecules.
