OBJECTIVE:To observe the short-term efficacy and safety of nimesulide combined with ibuprofen in the treatment of pain. METHODS:84 patients with pain were randomly divided into observation group and control group. Control group was oral-ly given 0.3 g Ibuprofen sustained-release capsule,twice a day. Observation group was additionally given 100 mg Nimesulide cap-sule,twice a day. The treatment course for both groups was 7 d. Clinical efficacy,visual analogue (VAS) score,quality of life (QOL) score,coagulation indexes (prothrombin time,thrombin time,fibrinogen,activated partial thromboplastin time) before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observa-tion group was significantly higher than control group,the differences were statistically significant(P<0.05). Before treatment, there were no significant differences in the VAS score and QOL score between 2 groups(P>0.05). After treatment,VAS scores in 2 groups were significantly lower than before,and observation group was lower than control group,QOL scores were significantly higher than before,and observation group was higher than control group,the differences were statistically significant(P<0.05). And there were no significant differences in the coagulation indexes and incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:The short-term efficacy of ibuprofen combined with nimesulide is superior to ibuprofen alone in the treatment of pain,with similar short-term safety.

To explore the therapeutic effects and toxic side-effect of 131I-McAb (S102, T9, CL-3) in the treatment of hepatocellular carcinoma (HCC). 131I-McAb, which was labelled by IODO-GEN method, with 50-70mCi of 131I, was percutaneously injected into the tumor under B-ultrasonic guidance in 116 patients. The results showed that the effective rate (CR+PR) was 29.3% (34/116), the overall effective rate (CR+PR+MR) was 53.4% (62/116), the one-year survival rate was 38.2% (39/102), the mean survival time was 34.7 weeks, and the mean tumor developing phase was 12 weeks. The results suggested that the use of 131I-McAb in the treatment of HCC is a low toxic, effective and minimal invasive operation.

Objective To study the effects of tyrosine kinase receptor B-brain-derived neurotrophic factor (TrkB-BDNF) signal pathway on the secretion of vascular endothelial growth factor (VEGF) and matrix metalloproteinases-9(MMP-9) of neuroblastoma.Methods We used all-trans retinoic acid (ATRA) to induce the high expression of TrkB in the SH-SY5Y cell line,and then added the ectogenid BDNF to activate the TrkB-BDNF and its three downstream signal pathways.TrkB-BDNF signal pathway was inhibited by specific tyrosine kinase inhibitor K252a.The three downstream signal pathway was respectively inhibited by LY294002 (the phosphatidylinositol 3-hydroxy kinase (PI3 K) pathway inhibitor)、U73122 (the phospholipase C pathway inhibitor) 、U0126(the mitogen activated protein kinase pathway inhibitor).Enzyme linked immunosorbent assay was used to detect the concentration of VEGF and MMP-9 protein in the SY5Y cell culture supernatants.Results VEGF [(485.89 ± 109.99) pg/ml] and MMP-9 [(15.73 ± 1.72) pg/ml] protein levels in neuroblastoma cells cultured in serum-free media in the group of ATRA + BDNF were significantly higher than that of the control group and ATRA alone group(P ＜0.05).VEGF [(272.42 ±86.33) pg/ml]and MMP-9 [(5.25 ± 1.44) pg/ml] protein levels in the group of ATRA + BDNF + K252a were significantly lower than those of the ATRA + BDNF group(P ＜ 0.05) and had no significant difference compared with the control group and the ATRA alone group(P ＞0.05).VEGF [(314.12 ±24.68) pg/ml] and MMP-9 [(4.91 ± 1.08) pg/ml] protein levels in the group of ATRA + BDNF + LY294002 were significantly lower than those of the ATRA + BDNF group(P ＜ 0.05) and had no significant difference compared with the control group and the ATRA alone group(P ＞0.05).VEGF [(444.08 ±64.49) pg/ml] and MMP-9 [(13.28 ±3.38) pg/ml] protein levels in neuroblastoma cells cultured in serum-free media in the group of ATRA +BDNF + U73122 had no significant difference compared with the ATRA + BDNF group(P ＞ 0.05).VEGF [(429.97 ± 19.95) pg/ml] and MMP-9 [(13.96 ± 4.45) pg/ml] protein levels in neuroblastoma cells cultured in serum-free media in the group of ATRA + BDNF + U0126 had no significant difference compared with the ATRA + BDNF group(P ＞ 0.05).Conclusion Activation of TrkB-BDNF signal pathway can increase the synthesis and secretion of VEGF and MMP-9 in human neuroblastoma cells.TrkB-BDNF signal pathway may be through activating its downstream PI3K pathway to increase the synthesis and secretion of VEGF and MMP-9 in human neuroblastoma cells.The synthesis and secretion of VEGF and MMP-9 can be inhibited by blocking the TrkB-BDNF signal pathway with K252a or blocking its downstream signal pathway PI3 K with LY294002.

ObjectiveTo study the anatomical abnormalities of basal ganglia and research their influence on depression status in patients with post stroke depression (PSD)by diffusion tensor imaging (DTI) of MRI.MethodsPatients with basal ganglia infarction were recruited,and divided into groups of PSD and non depression control group by Hamilton Depression Rating Scale (HAMD) assessment. All the patients were evaluated with National Institute of Health Stroke Scale ( NIHSS). And the patients were checked by DTI sequence.Fractional anisotropy (FA),average diffusion coefficient (ADC) values and the number of nerve fiber were measured in bilateral caudatum,pallidum,putamen and thalamus.ResultsThe score of NIHSS (6.29 ± 3.45 ) was significantly higher in PSD group than that in non-depression group (3.95 ± 1.90 ;t =2.219,P =0.036). No significant difference was found between the two groups for the DTI data of the basal ganglia nuclei ( t =0.056-1.618,all P ＞ 0.05 ). Compared with contralateral construction (0.40 ± 0.02 ),the FA value decreased in the left putamen ( 0.37 ± 0.03 ) in the PSD group ( t =2.243,P =0.045 ).By Spearman correlations analysis,the HAMD score was positively correlated with NIHSS score ( r =0.464,P =0.017 ),and negatively correlated with the FA values of left pallidum (r=-0.563,P=0.005),right pallidum (r=-0.416,P=0.035) and left putamen (r =-0.428,P =0.029).Conclusions The occurrence of PSD was associated with neurological functional deficit following basal ganglia infarction.The depression level was correlated with the increasing of NIHSS score,the reductions in bilateral pallidum and left putamen FA values.This research contributes to evaluation of the PSD status in patients with basal ganglia infarction.

Objective To investigate the changes and the role of plasma thrombomodulin(TM),von willebrand factor (vWF) ,and coagulation status indicators in children with Henoch-Schonlein purpura(HSP).Methods The plasma concentrations of TM,vWF were measured by ELISA method and the levels of D-dimer,PT,APTT,palatelet count were measured in 56 acute SHP patients,50 recovery patients and 40 healthy controls. Results The plasma levels of TM、vWF、D-dimer、palatelet count in acute group were significantly higher than those in healthy controls group and those of recovery group ( P = 0. 000). The plasma levels of PT、APTT showed no significant difference among three groups( P ＞ 0. 05 ). The plasma levels of TM、vWF in recovery group were significantly higher than those in healthy controls group ( P ＜ 0. 05, P ＜ 0. 01 ), while the levels of D-dimer、palatelet count reduced to nomal levels(P ＞0. 05). As compared to non-renal damage group, The plasma levels of TM、vWF、 D-dimer were higher in renal damage group ( P ＜ 0. 05, P ＜ 0. 01 ), the levels of PT 、APTT、palatelet count showed no significant difference ( P ＞ 0. 05 ). Conclusion The damage of vascular endothelium and hypercoagulability play an important role in the pathogenesis of HSP. Changes of plasma TM、 vWF、palatelet count can be used as an indicator of the early lesion of renal function.

Objectives To investigate the overall prevalence of cardiovascular disease (CVD) in subjects hospitalized for chronic obstructive pulmonary disease (COPD),and explore the prevalence of the major CVD complications and trends in patients with COPD over a 10-year period.Methods Medical records in the PLA General Hospital,Beijing Union Medical College Hospital,and Beijing Hospital from 2000/01/01 to 2010/03/03 were retrospectively reviewed.A total of 4960 patients with COPD were reviewed in the study (3570 males,mean age,72.2 ± 10.5 years; 1390 females,mean age,72.0 ± 10.4 years).Results The prevalence of CVD in COPD patients was 51.7％.The three most prevalent CVDs were ischemic heart disease (28.9％),heart failure (19.6％),and arrhythmia (12.6％).During the 10-year study period,the prevalence of various CVDs in COPD patients showed a gradual increasing trend with increasing age.There was higher morbidity due to ischemic heart disease (P ＜ 0.01) in male COPD patients than in the female counterparts.However,heart failure (P ＜ 0.01)and hypertension (P ＜ 0.01) occurred less frequently in male COPD patients than in female COPD patients.Furthermore,the prevalence of ischemic heart disease decreased year by year.In addition to heart failure,various types of CVD complications in COPD patients tended to occur in younger subjects.The prevalence of all major types of CVD in women tended to increase year by year.Conclusions The prevalence of CVD in patients hospitalized for COPD in Beijing was high.Age,sex and CVD trends,as well as life style changes,should be considered when prevention and control strategies are formulated.
