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.

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.

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.

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.

BACKGROUND: Continuous passive motion assisted with diathermia will promote the restoration of joint movement of the extremities.OBJECTIVE: To improve joint movement with continuous motion assisted with diathermia after surgical treatment on simple fracture of upper or lower extremity.DESIGN: A randomized controlled trial.SETTING: Huaxi Hospital of Sichuan University.PARTICIPANTS: Eighty-four cases of simple extremity fracture treated in the Orthopedic Department of Huaxi Hospital of Sichuan University from October 2000 to July 2002 were included in this trial. Of them, 16 cases were elbow movement disorder and 68 were knee movement disorder. They were randomly assigned into two groups with 42 cases each.METHODS: The 42 cases in the treatment group were preheated before continuous passive motion while those in the control group just received continuous passive motion. The improvement of joint movement between thetwo groups were assessed and compared according to the joint movement scale.MAIN OUTCOME MEASURES: The joint movement before and after treatment and the indices of joint movement scale in the two groups.RESULTS: All of the eighty-four cases entered the analysis. The joint movement in the treatment group was better than that in the control group [ (101.40 ± 25.76)° vs (86.14 ± 27.66)°, t = 5.25, P ＜ 0.01 ]. The index of joint movement scale in the treatment group was also higher than that of the control group[ (84.32 ± 16.54) vs(64. 89 ± 13.76) ] ( t = 4.24, P ＜ 0.01 ) ].CONCLUSION: Continuous passive motion assisted with diathermia is better than simple continuous passive motion in improving the joint movement and function of elbow and knee.

Readiness for hospital discharge is an important measure to ensure the safety of patient discharge. Evaluating the readiness for hospital discharge can help medical staff to avoid premature discharge of patients and to reduce the incidence of complications and readmission rate. This paper reviews the concept, content and tools of assessment, and the research interests and fields of discharge readiness, so as to provide help and support for further research.

Medical adhesive is widely used in the medical care environment,but the medical staff pays little attention to skin injury caused by it.The incidence of medical adhesive-related skin injury is relatively high,and the patients may suffer from pain,infection and so on,result in lowering quality of life.On the basis of literature review,the author reviewed the epidemiology,pathophysiology,types,risk factors,prevention and treatment of the medical adhesive-related skin injury to provide the basis for prevention and care of such skin injury.

In this paper a series of gait quantitative assessment indexes:phase symmetry index,verti-cal force symmetry index,equilibrium function index,and brake and drive function indexes are obtainedwith VICON 3-dimensinal movement analysis system according to the results that 40 amputees,50 cerebralpalsy patients, 31 hemiplegia patients and 19 paraplegia are evaluated and the differences between the nor-mal and the abnormal(p<0.001)found with these indexes. The quantitative assessment methed of walk-ing function not only provides rehabilitation level of patients and for checking therapeutical effects,but alsolaies the foundation of gait analysis to standardization and practicalization further.

Objective:To investigate the relationship between the location of anterior cruciate ligament rupture (ACL) and the areas of bone bruises in patients with an acute ACL injury.Methods:A retrospective study was conducted on MRI of patients with ACL injuries from January to June 2019. According to the location of the ACL rupture on the distal to proximal length, the patients were divided into 5 groups, namely Type I, >90%; Type II, 75%-90%; Type III, 25%-75%; Type IV, 10%-25%, Type V, <10%. Gender, weight, body mass index, depth of lateral femoral condyle notch, and medial meniscus injury were compared among the five groups. The sagittal plane images of ePDWSPIRCLEAR sequence were selected to define the layer with the largest contusion areas of femur and tibia respectively. The maximum bone contusion areas of these two layers was measured using Image J 1.52t software.Results:Among the 63 cases of acute ACL injury, three cases (4.8%) were with type I tear, 14 cases (22.2%) with type II tear, 40 cases (63.5%) with type III tear, 2 cases (3.2%) with type IV tear, and 4 cases (6.3%) with Type V tear. There was no contusion of lateral femoral condyle or lateral tibial plateau bone in type I and type IV. The lateral femoral condyle bone contusion areas was 0 (0, 64.12) mm 2 in type II, 182.34 (86.58, 334.38) mm 2 in Type III, 38.64(0, 193.36) mm 2 in Type V with statistically significant difference ( H=21.665, P=0.000). The largest areas of bone contusion in the lateral tibial plateau was 76.78(28.25, 205.57) mm 2 in type II, 120.93(51.78, 239.37) mm 2 in Type III, 190.51(80.86, 238.75) mm 2 in Type V with statistically significant difference ( H=11.939, P=0.018). The maximum bone contused areas of the lateral tibial plateau in the medial meniscus injury group was 48.0(0, 105.97) mm 2, which was smaller than that in the non-injury group 185.67(54.36, 257.41) mm 2 ( H=8.848, P=0.003). The maximum bone contusion areas of the lateral femoral condyle in the injured group was 162.19(63.03, 301.33) mm 2, which was greater than 0(0, 103.37) mm 2 in the uninjured group ( H=11.554, P=0.001). Conclusion:ACL rupture often occurs in the middle segment. The middle segment ACL fracture combined with lateral meniscus injury had with the highest probability and with the largest area of bone contusion of lateral femoral condyle. The fracture of the ACL at the farthest terminal has the largest bone contusion areas of the lateral tibial plateau and with the lowest probability of combined injury of the medial meniscus.
