0.05).After exposure of U937 macrophages to 11.1 mmol/L,16.7 mmol/L and 33.3mmol/L glucose,the expression of LOX-1 protein was 1.56-,2.26-and 2.96-fold,as compared with that of 5.6 mmol/L glucose group(P

Objective To evaluate the effect of 3-dimmentional conformal radiotherapy (3-DCRT) for mediastinal metastasis from esophageal carcinoma after surgery.Methods Sixty-three such patients were treated by 3-DCRT. Tumor diameter was: cm 20 patients. Positive supraclavicular lymph node was found in 9 patients. The number of tumor at the upper right, upper left and upper median mediastinum was 27, 27 and 20. All patients received 3-DCRT to the dose of 40?Gy (2?Gy/f, 5f/w), after resetting of portals, the dose was boost to 64～70?Gy by 3?Gy/f, 5f/w. Dose of the patients who had been irradiated was boosted to 50?Gy without further positioning. Results Complete response rate and partial response rate were 43% and 48% one month after the treatment was concluded,with no progression of disease. The 1-, 2- and 3-year survival rates were 75%, 43% and 15%. Conclusions Three-dimmentional conformal radiotherapy, with little side-effects, can markedly improve the local control rate and suvival rate of patients with mediastinal metastasis from esophageal carcinoma after surgery.

Objective To investigate the effects of different analgesia protocols on immune function in patients undergoing surgery for ovarian neoplasms after neoadjuvant chemotherapy.Methods Forty ovarian neoplasms patients ageing from 31 to 62 years undergoing neoadjuvant chemotherapy were randomly divided into 2groups:epidural analgesia group (group E,n =20) and intravenous analgesia group (group Ⅰ,n =20).All patients underwent surgery under total intravenous general anesthesia.Patients in group E were given 2 mg morphine in epidural space at half an hour before abdomen was closed,then epidural analgesia pump was installed,with ropivacaine composite morphine in the pump.Analgesia time was 48 h.Patients in group Ⅰ were given sufentanil 0.1 μg/kg intravenously at half an hour before abdomen was closed,then analgesia pump was installed,with sufentanil compound flurbiprofen ester in the pump.Analgesia time was 48 h.The cervical venous blood samples were obtained from the patients at 30 min before surgery(T0),immediately(T1),12 h(T2),24 h(T3) and 48 h (T4) after the end of operation for determination of the expression of CD3 +,CD4 +,CD8 + on T cells and natural killer cell.Visual analogue scales (VAS)and adverse reaction at T2-4 were recorded.Results No statistical difference was found between group E and group Ⅰ in VAS and adverse reaction.Compared with T0,CD3 +,CD4 + T-lymphocytes,CD4 +/CD8 +,and NK cell decreased.Compared with group E,CD8 + increased at T1-2in both groups and at T3-4 in group Ⅰ.CD3 +,CD4+ T-lymphocytes,CD4+/CD8 + and NK cell decreased while CD8 + increased at T2-4 in group Ⅰ.Conclusion Epidural analgesia may be better to promote the immunologic function of ovarian neoplasms patients undergoing surgery after neoadjuvant chemotherapy.

Objective To explore the value of echocardiography in the diagnosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in children.Methods The echocardiographic images of 14 patients with ALCAPA confirmed by operation and 18 patients with endocardial fibroelastosis (EFE) diagnosed by clinical were compared and analyzed.Results Both ALCAPA and EFE exhibited obvious dilated left ventricle,decreased left ventricular systolic function,thick endocardium and mitral regurgitation of different degree.The former additionally showed dilated right coronary artery(RCA) with normal origin,left coronary artery(LCA) emerging from the root or wall of the pulmonary artery(PA),the retrograde flow into PA in LCA and abundant collateral vessels in myocardium.However the later exhibited normal diameter of LCA and RCA and no collateral vessels.Conclusions Color Doppler echocardiography not only demonstrates left ventricular systolic function,endocardium,mitrial regurgitation and collateral vessels in myocardium,but also shows the origination and courses of LCA clearly,which provide exact informations to diagnose ALCAPA.The echocardiography can be used as a powerful tool of ALCAPA diagnosis and preoperative assessment.

ObjectiveTo observe the dynamic changes of blood perfusion and hypoxic status by CT perfusion imaging and hypoxia imaging in patients with non-small cell lung cancer (NSCLC) after treatment with recombinant human endostatin (RHES). MethodsA total 15 patients with NSCLC were randomly divided into treatment group (n = 10) and control group (n = 5). The patients in treatment group continuouly received the treatment with RHES (7.5 mg/m2) by intravenous infusion for ten days, and CT perfusion imaging and hypoxia imaging were performed at day 1, 5 and 10,respectively. The time window' was observed with the blood perfusion status and hypoxic changes.ResultsIn the treatment group, capillary permeability surface (PS) and tumor to normal tissue (T/N) were firstly decreased, and then increased. Their lowest points occurred at about the fifth day. PS showed statistical significance compared with the first day (q1.5 = 12.05, P＜0.01 ) and no significance compared with the tenth day(q10.5 = 2.79, P=0.69), while T/N showed a significant difference between above time points (q1.5 = 73.81, q10.5 = 20.6, P = 0.00).Blood flow (BF) was firstly increased, and then decreased.Its highest point appeared at about the fifth day with statistical significance compared with the first and tenth day (q1.5 = 12.29, q10.5 = 10.48, P＜0.01 ). All the PS,BF and T/N between the fifth day in treatment group and the control group showed statistically significance (all P ＜ 0.01 ).Conclusions The time window of recombinant human endostatin improving blood perfusion and hypoxic status in non-small cell lung cancer is within about one week after administration.

Haemophilia is caused by lack of coagulation factor VIII or IX in patients′blood with inadequate hemostasis.Currently recombinant coagulation factor VII(rFVII)produced in different cells is used against clini-cal bleeding of haemophilia patients.To enhance the production and activity of rFVII;some eukaryotic cells such as baby hamster kidney(BHK);Chinese hamster ovary(CHO);insect cell and fish embryo;were used to express rFVII.Meanwhile;the effect of functional gene on the activity of rFVII and the limitation of rFVII production caused by post-translational modification were investigated by different methods.The role of rFVII in hemostasis;synthesis of rFVII in different eukaryotic cells and impact on production of post-translational modification are reviewed in this article.
