Objective To investigate the significance of combined detection of serum tumor markers in the diagnosis of lung cancer,and to select the most sensitive serum tumor markers.Methods Enzyme-linked immunosorbent assay was used to detect the serum tumor markers of 62 lung cancer patients and 62 healthy persons,who were neuron specific enolase enzyme (NES),carbohydrate antigen 125 (CA 125),cytokeratin 19 (CYFRA21-1) and carcinoembryonic antigen(CEA).Results The level of serum CEA,CA125,CYFRA21-1,and NES of the lung cancer group were all higher than those of the control group (all P ＜ 0.05).Among the four kinds of tumor markers,CA125 had the highest sensitivity(59.7％),which was followed by CEA(53.2％).The sensitivity of the four kinds of joint detection was 87.1％,the highest sensitivity of three markers joint detection was CEA + CA125 + CYFRA21-1 (87.1％),while that of the two kinds of joint detection was CEA + CA125 (75.8％).Conclusion There are high clinical significance in the diagnosis of lung cancer with four kinds of serum tumor markers,CEA + CA125 + CYFRA21-1 can be used as the best markers for joint detection of lung cancer with high sensitivity.

0.05).Conclusion The gene polymorphism of MMP-9/C1562T may be unrelated with IS.

Objective To observe the neuroprotective effect of Gangliosides on rats with cerebral ischemia-reperfusion. Methods Rat models were established through middle cerebral artery occlusion and divided into sham-operation group, ischemia-reperfusion group and Gangliosides group. The volume of infarotion and changes of NAA and Lactate at different time point were evaluated by DWI and MRS examinations. Results The mean infarcted volume measured by DWI at 1 h, 3 h and 6 h after ischemia-reperfusion in Gangliosides group was (30.32?8.18) mm3, (35.17?12.45) mm3 and (31.4?8.56) mm3, respectively, versus (204.6?37.77) mm3, (218.9?67.33) mm3 and (213.4?99. 95) mm3 in ischemia-reperfusion group.There were significant differences between the two groups (allP

Objective To investigate the role of hepatocyte growth factor(HGF),keratinocyte growth factor(KGF) and interleukin-1β(IL-1β) in tracheal aspirates (TA) in the genesis and development of acute respiratory distress syndrome (ARDS).Methods The levels of HGF,KGF and IL-1β in TA of 25 children with ARDS (ARDS group) and 23 children with non-ARDS (control group) were assayed by ELISA.Lung injury score was applied to all patients.Results The levels of HGF,KGF and IL-1β in TA were significantly higher in ARDS group than in control group(P<0.0 1).As compared with survivors,the levels of HGF,KGF and IL-1β in TA were markedly higher in dead patients(P<0.01).LIS had a positive correlation with the levels of HGF,KGF and IL-1β(P<0.01).Conclusion HGF,KGF and IL-1β participate in the development of ARDS.The degree of lung injury and prognosis of ARDS may be early estimated by the levels of HGF,KGF and IL-1β in TA.

Objective Measuring the concentration of PTH when pcDNA3.1?PTH was injected into the muscle of rabbits with hypoparathyroidism (HPT),studying the relationship between change of blood PTH and pcDNA3.1?PTH dosage.Methods Different dosages of pcDNA3.1?PTH(100?g/ml, 300?g/ml and 500?g/ml)containing human PTH gene were injected respectively into muscle of the experimental rabbits after parathyroidectomy in advance.Then the concentration of PTH in blood of rabbits was measured at following different times.Results PTH level began to increase from the first day,which reached in peak concentration at the seventh day after the injection of pcDNA3.1?PTH and persisting two months.Conclusion Human PTH gene was effective in therapying HPT rabbits,their best effective dosages were 300?g/ml and 500?g/ml respectively.

ObjectiveTo discuss the causes, preventions and treatments of fractures after spinal cord injury (SCI).MethodsA retrospective survey was carried out in the clinical data of 22 patients who suffered fractures after SCI in China Rehabilitation Research Center (CRRC) during 1988-2001.ResultsAll the patients showed osteoporosis or osteopenia in different degrees,fractures occured unconsciously or during minor force,without symptoms after fractures.It was difficult to discover and often was neglected. 15 patients were cured by surgical operation.Conclusions Osteoporosis is the pathological base of fractures after SCI, excess loading stress in the diaphysis is the main cause during joint movement passively, it is important to emphasize preventions and treatments of osteoporosis on early stage and the health propaganda and education is needed.

To search the effective health education to the hypertension patients and to decrease complication such as cerebrovascular ailment,106 hypertension patients were divided into two groups randomly:the interference (52) and the control (54).The interference group is treated with health education and health promotion constantly (Base line:1996,end line 1999).The results of 2 times investigations at the base line and end line respectively to the groups show that:the KAB in both groups were improved,and the interference improved notably,especially in behavior.The percentage of the patients who care about danger factors and hygeine knowledge rise from 68% (base line) to 78.6% and the percentage of the patients who did exercise constantly rise from 58.9% to 71.4%.It is also showed that,in periodic measurement of blood pressure and regular administration of medicine,the interference group behaved better than the contrast (P<0.01).We can conclude that giving face to face health education and health promotion to hypertension patients is a effective way to prevent and control hypertension complications

Objective To explore the levels and clinical significance of anti-beta 2-glycoprotein 1 antibodies (β_2GP1), matrix metalloproteinase 9 (M M P-9) in the plasma of children with Kawasaki diseases (KD). Methods Serum level of anti-β_2GP1 antibody and MMP-9 was measured in 47 children with KD by ELISA, and the data was analyzed using SPSS11.5 software. Thirty age matched children with infectious diseases(sepsis or pneumonia), exclusive of heart, liver, kidney, blood diseases and autoimmune diseases such as rheumatoid were chosen in the fever control group. Results Coronary artery lesions (CAL)were found in 17 children of KD group (17/47) by Doppler ultrasound examination. Significant differences (P < 0.05) of serum level of anti-β_2GP1 antibody was showed between KD group ((7.46 ± 2.13) U/ml)and the control group ((4.38 ± 0.43) U/ml) ; serum level of MMP-9 was (886.62 ± 92.72) ng/ml and (460.06 ± 179.59) ng/ml in KD group and the control group respectively, with significant difference between the two groups(P < 0.05). In KD group, levels of anti-β_2GP1 were (8.83 ± 0.89) U/ml among children with CAL and (6.18 ± 1.42) U/ml among children without CAL, serum level of MMP-9 was (948.62 ± 81.76) ng/ml and (872.00 ± 34.74) ug/ml respectively, with significant differences(beth P < 0.05). In children with KD, the serum levels of anti-β2GP1 antibody and MMP-9 were significantly correlated (correlation coefficient r = 0.665). Conclusions Serum levels of anti-β_2GP1 antibodies and MMP-9 increased in the acute phase of KD, and were significantly higher in those KD children with CAL.Anti-β_2GP1 antibodies and MMP-9 may play a role in the pathogenesis of KD, and can be used as an important serological indicator of KD with CAL.
