Objective To explore the risk factors of vascular dementia (VD) in stroke patients, expecial-ly, the relationship between VD and carotid artery atherosclerosis. Methods 64 patients with cerebrovascular dis-ease , who had a history of stroke , were divided into VD groups (n = 64) and control group (n = 60). The age, disease course, education and blood lipid and carotid artery stenosis were compared. Results The age of patients , course of disease ,educational levels, the serum levels of TC ,TG, LDL and internal diameter of carotid artery were different between the two groups (P < 0.05 ). Conclusion The age of patients , course of disease , education, the serum levels of TC ,TG ,LDL and carotid artery atherosclerosis are related to vascular dementia in stroke patients.

Objective To investigate the change of immunologic function of red blood cell (RBC) in patients with chronic gastritis. Methods The immunologic function of RBC in 88 cases of chronic gastritis was dynamically detected with yeast rosette method. Results The results showed that RBC-C3b receptor rosette (RBC-C3b-RR) rate and RBC immune adherence enhance factor (RFER) rate were significantly lower (P＜0.05) and RBC immune complex rosette (RBC-ICR) rate and RBC immune adherence inhibitor factor (RFIR) were significantly higher (P＜0.05) in the patients with atrophic gastritis than those in control group. In the patients with superficial gastritis, the difference had no distinct significance (P＞0.05). Conclusion The immunologic function of red blood cell (RBC)measurement plays an important role in differential diagnosis and prognosis evaluation of chronic gastritis.

As quantum dots( QDs),an advanced porduct of nanotechnology,have been widely used in bio-medicine due to their unique photoelectric properties. QD safety evaluation has become a hot area of research. So far,some researchers have expressed concern about the neurotoxic potential of QDs because the central nervous system was confirmed to be one of the target organs. Several studies found that QDs could enter the central nervous system by crossing the blood brain barrier and following neural pathways and produce some neurotoxic effects,such as damaging the structure and function of neural cells and impairing synaptic plasticity. The potential toxicity mechanisms could include oxidative stress,inflammation and change of ion channels.

Objective To investigate the clinical value of the 18F-FDG SPECT-CT combined with the image of CT in the diagnosis of lung cancer.Methods Retrospectively analysis images of 18F-FDG SPECT-CT and CT of 162 patients pulmonary tumor-like lesions from January 2013 to October 2013 were conducted.All the patients have been confirmed by the pathological mechanism or cytologic examination.Each patient has been firstly diagnosed by the 18F-FDG SPECT-CT along and then combined with the images of CT.The sensitive rate and the accurate rate of two methods were compared by x2 test.Results There were 40 benign lesions and 114 malignant ones in 162 patients.The sensitive rates of the two methods were 86.0％ and 96.5％ (x2 =6.63,P ＜ 0.05).The accurate rates of the two ways were 79％ and 96.3％ (x2 =7.76,P ＜ 0.05).The differences were statistically significant.Conclusion 18F-FDG SPECT-CT combined with the images of CT can increase the diagnostic sensitivity and accuracy.It has important clinical value.

Inflammatory bowel disease( IBD)is a group of chronic nonspecific intestinal diseases characterized by a clinical relapsing-remitting behavior. The evaluation of disease activity is concerned by clinicians all the time. With the evolving in recognition of the pathogenesis of IBD,many novel biomarkers are emerging in recent years. This article reviewed advances in the accepted and ongoing research fecal markers of IBD.

Objective To investigate the effect of medial collateral ligament reconstruction using semitendinosus autograft.Methods A total of 12 patients with medial collateral ligament injury received knee examinations.Among them,2 had lateral meniscus injury,and received partial resection of the lateral meniscus;2 had cruciate ligament(CL) injury(anterior CL in one and posterior CL in the other),and underwent bone-ligament-bone reconstruction.Medial collateral ligament reconstruction was performed using the semitendinosus tendon autograft ingrowth in the tibial tunnel.Results Primary healing was achieved in all the cases.In 10 of them,the stability of the knee was regained in 6-month follow-up;stress X-ray examination showed that the medial joint space was smaller than the contralateral one by less than 5 mm,and the position of the interference screw was optimal.Of the 12 patients,11 achieved an active knee flexion between 0? and 120?,the other,who had fracture of the lateral condyle of the femur,had a flexion of 90?.Conclusions Semitendinosus autograft provides sufficient tension for medial collateral ligament reconstruction.The fixation of the knee and the closure of the joint capsule can be achieved by using the method.

Autoimmune hemolytic anemia is a disorder of immune function caused by various reasons, by produceing autoantibody or complement which can react with erythrocyte autoantigen, increasing the destruction of red blood cell and beyond the compensatory ability of bone marrow hematopoiesis.Children usually have acute onset and the clinical manifestations are related to the pathogenesis.As the first-line treatment of glucocorticoids, Most children respond well to glucocorticoids.Some children suffer from steroid dependence and resistance; or recurrence due to different types of antibodies, often requiring second-line treatment, such as splenectomy, immunosuppressive, etc.This article reviews the recent progress in the treatment of children with autoimmune hemolytic anemia.

Objective To explore the consistency of chemiluminescence microparticle immunoassay(CMIA)reagent and particle‐enhanced turbidimetric immunoassay(PETIA) reagent for detecting pepsinogen(PG) ,so as to provide laboratory references for en‐suring the reliability of PETIA reagent in detecting PG .Methods According to the requirement of EP9‐A2 file made by the Nation‐al Committee for Clinical Laboratory Standards(NCCLS) ,taking PETIA as evaluating method and CMIA as reference method ,a to‐tal of 92 specimens collected from patients with various degrees of gastric atrophy were selected ,PETIA and CMIA reagents were utilized for bidirectional detection of PG .Then recorded test results of pepsinogenⅠ(PGⅠ) ,and PGⅠ /pepsinogenⅡ(PG Ⅱ) rati‐o ,and carried out method comparison and bias evaluation for the two kinds of reagents .Results The expected relative bias of detec‐tion results of PGⅠ and PGⅠ /PG Ⅱ ratio by using PETIA and CMIA reagents were acceptable within linear range of methods . Conclusion The results of PGⅠ and PG Ⅱ detected by using PETIA reagent could be accepted .
