Objective　To study the factors effecting the formation of the ventricular aneurysm post myocardial infarction (MI) and evaluate the diagnostic methods.Methods　23 MI patients with ventricular aneurysm confirmed by left ventricular angiography were observed for electrocardiogram (ECG), echocardiogram (ECHO), coronary disease and collateral vessels formation. Results　All patients had LAD disease, 65.2% patients had three coronary disease, and those with class Ⅲ collateral vessels circulation only 17.4%. Compared to ECHO by which only 4 patients were found aneurysm, the positive rate by ECG was 82.6%. Conclusion　Patients with multiple coronary disease and without enough collateral vessels are expected to form ventricular aneurysm. ECG is more sensitive than ECHO for diagnosis of ventricular aneurysm post MI

Objective To analyze the morbidity rate and clinical etiology distribution of secondary thrombocytosis(ST ) in chil‐dren in order to guide the clinical treatment .Methods The clinical data of 170 children patients with ST in hospitals were retro‐spectively analyzed for investigating its etiology distribution ,total morbidity and onset situation in different age periods . Results The primary etiologies of ST mainly included the infectious diseases(especially respiratory tract) ,anemia ,immune disea‐ses ,drugs ,surgical disease ,etc .Thrombocytosis caused by neonatal diseases also were common .The total morbidity rates of ST in children was about 3 .37% and which in newborns ,infants and children aged over 3 years were 2 .48% ,3 .78% and 1 .99% respec‐tively ,the difference was statistically significant(P<0 .5) .Conclusion ST is one of the common complications in children ,especial‐ly in children aged under 3 years old .The etiology of ST is various ,which are dominated by respiratory and digestive tract infec‐tions .Children aged under 3 years old ,especially infants and young children with respiratory tract infection are easier to suffer from complicating thrombocytosis .

Cytokine induced killer (CIK) cells are the main immune cells for tumor immnuotherapy.Relevant basic researches show that CIK cells have significant antitumor effects for various hematologic tumor and solid tumors.Clinical studies confirm that CIK cells-based therapy have exact therapeutic effect and mild adverse reaction for tumor patients.So CIK cells-based therapy is a promising and safe method and it is important to establish standards for cultivating and using CIK cells.

Low molecular weight heparin(LMWH)is a kind of anticoagulant used in both the prevention of clot formation in the blood vessels(thrombosis)and the treatment of conditions caused by clot formation or embolization.They are agents formulated from chemical or enzymatic depolymerization of unfractionated heparin.In the past decade,LMWH has been extensively evaluated in many clinical settings.The applications of LMWH in recent years are reviewed.

Objective To investigate the roles of hypoxia regulated genes/protein in chemical hypoxia preconditioning in differentiated SH-SY5Y cells.Methods Differentiated SH-SY5Y cells were randomly divided into control group,chemical hypoxic preconditioning group(50 ?mol/L CoCl2 preconditioning for 3 h,normal culture for 1 h,then in 2%O2 for 28 h) and hypoxia group(in 2%O2 for 28 h).RT-PCR was used to examine the mRNA expressions of VEGF,GLUT-1,EPO,LDH-A.Further evaluation of the potential neuroprotective effect of VEGF was done by investigating the effect of recombinant human VEGF on subsequent hypoxia injury.Results The mRNA levels of GLUT-1,EPO increased in the preconditioning group as compared with those in the hypoxia group(P

Objective To investigate the changs of serum and urine vascular endothelial growth factor(VEGF) in children with steroid-sensitive nephrotic syndrome(SSNS) at their active and remission stage.Methods Serum and morning urine levels of VEGF were assayed by Liquichip in 30 patients with SSNS at the active and remission stage and 30 normal age-and sex-matched controls.Results Serum levels of VEGF in patients at the active stage [(186.62?106.21) ng/L] were significantly higher those that at the remission stage [(118.75?73.08) ng/L] and than those in control group [(108.64?54.75) ng/L](P0.05).Morning urine levels of VEGF in patients at the active stage [(201.66?100.46) ng/L] were significantly higher than those at the remission stage [(116.35?55.99) ng/L] and than those in control group [(99.94?42.07) ng/L](P0.05).Conclusions Serum and morning urine levels of VEGF are significantly elevated in patients with SSNS,however they are significantly lower after the treatment of steroid.There is no obvious difference between the patients at the remission stage and healthy controls.VEGF involves pathogenetically and physiologically in SSNS during its onset and growth.

The titer of Interleukin-2 (IL-2), prepared from the healthy human peripheral blood lymphoytes which were stimulating-induced by carboxymethy-parchymaran (CMP), was very high and reached clinical drug level after special process. The IL-2 was not only available for intramuscular injection. but also for intravenous in jection or even for intraarterial, injection 44 partients with advanced malignant tumor treated with the combination of IL-2 / LAK and chemotherapy showed an overall objective response rate to 86. 4% (CR + PR: 13, 29.3%); (CR + PR + MR: 22, 50%); (CR + PR + MR + SR : 38, 86. 4%) . 37 Patients with various malignant tumors were treated by low-dose interleukin-2 stinulated with CMP and irradiation with 60Co. The percentages of CR, PR and SR were 51.4%, 46.8%and 2.7%, respectively. Overall effectiveness rate was 97.3%. 1 year survival rate was 86.2%. 16 Patients with various advanced cancers were treated by low-dose interleukin-2 stimulated with CMP and low - dose radiotherapy or chemotherapy. The percentage of CR, PR and SR was 37. 5%, 56. 3%and 6 . 3%, respectively. Overall effective rate was 93. 8%. 1 year survival rate was 87. 5%. The current results indicate that the possibility of combined therapy of the low - dose IL-2/LAK adoptive chemoimmunotherapy and radiotherapy or chemotherapy may be effective in treatment of advanced cancer.

Objective To assess the value of ECG in the diagnosis of acute pulmonary embolism (APE). Methods Twenty-eight patients with APE were included,with mean age of 56?16,and PaO 2,electrocardiogram (ECG),echocardiogram (ECHO) and ventilation/perfusion lung scan were performed. Results 96.4% patients had risk factors,and had different degree of hypoxia. 92.9% patients had ECG changes,most of whom (57.1%) showed ST-T changes. The ventilation/perfusion lung scan confirmed the diagnosis. Conclusion Considering the clinical symptom,arterial blood gas analysis,the early changes of ECG are useful in the diagnosis of the APE.
