Objective To investigate the effect and safety of urinary kallidinogenase on acute cerebral infarction.Methods One hundred and sixty-four patients with acute cerebral infarction were randomly divided into two groups:treatment group with urinary kallidinogenase(86 cases)and control group (78 cases).According to Chinese guidelines for prevention and management cerebrovascular disease,two groups were treated with basic therapy,such as antiplatelet,neurologic protection,blood pressure control,and so on.On basis of control group,treatment group Was administrated intravenous injection of urinary kallidinogenase 0.15 PNA U per day for 10 days.The primary efficacy Was evaluated by the National Institutes of Health Stroke Scale(NIHSS)score and Barthel index.Results The score of NIHSS and Barthel index at 15 days after treatment in the treatment group were higher than those in the control group[(6.67±3.02)scores vs(7.42±3.02)scores;75.36±23.56 vs 68.36±22.36,P＜0.05].Urinary kallidinogenase could significantly reduce neurological deficits in big artherosclerosis type by TOAST typing.Conclusion Urinary kallidinogenase may be effective and safe in the treatment of acute cerebral infarction.

Objective To study the clinical features of diagnosis and treatment in children with low-risk myelodysplastic syndrome(MDS) and improve the diagnosis and treatment.Methods The examinations of 17 children with low-risk MDS were analyzed.The blood concentrations of cyclosporine,one of the therapeutic drugs,were monitored and the responses to the treatments were evaluated.Results Exa-mination of full blood count showed that the reductions of 3 cell types,2 cell types and 1 cell type were 11 (64.7%)cases,5(29.4%)cases and 1(5.9%)case,respectively.Reticulocyte count showed an increase in 82.4% of the patients and normal in 3 cases.Fourteen in 17 cases were hyperplastic marrow and 3 cases were hypoplastic marrow.Among all cases,one lineage,2 lineages and 3 lineages dyspoiesis were seen in 8(47.1%),7(41.2%) and 1 (5.9%)cases,respectively.One case showed no dyspoiesis.Cytogenetics examination showed normal in 10(58.8%) cases and abnormal in 7(41.2%) cases.Fifteen (88.2%) cases had normal proportions of CD59 negative cells,while 2 cases had higher proportions.The blood concentrations of cyclosporine that were tested in 9 cases at the end of the third week were in a range of 95.3-316.5 ?g/L.The therapeutic effect of 10 cases were evaluated at the end of the third month after being treated.Eight cases achieved haematological improvement and 2 cases didn′t.The rate of improvement was 80%.Conclusions The patients of low-risk MDS are mostly school-aged children and pancytopenia is the most common sign.The combination of predisone,cyclosporine and stanozolol agents shows good effect to treat low-risk MDS.The absorption of cyclosporine is different individually,so it is significant to adjust the dosage of cyclosporine according to the concentration regularly in clinical practice.

Objective To analyze prognostic factors in children with acute myeloid leukemia(AML).Methods Retrospective analyze the relationship between many factors of the diagnosed children with AML and their 3-years event-free survival(EFS).Statistics was analyzed with ?2 test.Results The 3-years EFS was 47.5%.According to the analysis of statistics,EFS of some children groups had statistical differences with their controls (P

Objective To observe the iodine state of patients with autoimmunity thyroid disease(AITD) in Shaanxi province,and to discuss the relationship between the metabolism of iodine and the occurrance,development and prognosis of AITD.Methods A total of 388 cases were collected,among whom 283 were patients with AITD,and 105 were patients with non-AITD.Questionnaires were designed to determine the general state of the patients,the size,shape and texture of the thyroid,the urinary concentration of iodine,the function of thyroid and the autoantibody of thyroid.The data were processed by SPSS12.0.Results The mean urinary concentrations of iodine in patients with GD,with HT,and the control group were 212?g/L,245.4?g/L,and 197.8?g/L respectively,which were statistically different.In the HT group,wich different urinary concentrations of iodine,there were no statistical difference of TGAb,TMAb,and HS-TSH.Conclusion Excessive in-take of dietary iodine may be related with AITD.

AIM: To observe and study the influence of cardiac sympathetic nerve on QT dispersion (QTd) and the circadian variations of QTd in experimental rabbits. METHODS: The rabbits were divided into experimental group (without cardiac sympathetic control by operation) and control group (with retained cardiac sympathetic control by operation, sham operation). QTd of both groups were measured and compared before and after the operation. The circadian variations of QTd were also observed in both groups. RESULTS: QTd in experimental group decreased significantly after the cardiac sympathetic nerves were excised (P

Objective To investigate the relationship among methotrexate(MTX) plasma concentration,dosage,clinical effecicy and toxicity, and to evaluate it′s clinical significance.Methods MTX was measured by a flurorescence polarization immunoassay in plasma samples obtained from acute lymphoblastic leukemia(ALL) patients treated in different doses of MTX, and these results were analyzed combined with clinical manifestations.Results 1.The average of plasma concentration at 24 hours increased with the increasing doses of MTX. The relapse rate decreased with increased plasma concentration;2.The cerebrospinal fluid(CSF) concentrations prior to the intrathecal MTXinstillation were all below the effective concentration, so the intrathecal MTX instillation was needed;3.No severe toxicity was observed in the study, because the plasma concentration was below the high risk.Conclusion The study of MTX plasma concentration provides us an objective basis for the individualized chemotherapy.
