Objective To investigate the relationship between CRP and CK-MB among acute and stable patients with COPD in Nanjing city. Methods Using case-control design, 81 COPD patients and 71 normal controls were selected. Both fasting venous and arterial blood samples were collected for COPD patients at the acute and the stable stage separately, while fasting venous blood samples were collected for controls during medical examination. The concentrations of CRP, CK-MB or PaO2 of all blood samples were examined. Results The concentration of CRP and CK-MB were significantly higher among stable COPD patients (7.18?5.62, 10.92?5.33; respectively) than those among controls(3.00?0.91, 3.11?1.46; respectively), while acute patients (51.22?24.53,30.06?16.68; respectively) got much higher concentration of CRP and CK-MB than stable patients did. However, PaO2 was significantly higher among stable COPD patients than that among acute patients. For acute COPD patients, the concentration of CK-MB positively correlated with CRP, while PaO2 negatively correlated with CRP and CK-MB separately. Conclusions CRP and CK-MB were sensitive predictors of COPD status to the transition from stable to acute stage of COPD, and both negatively correlated with PaO2 among these sample COPD patients.

Objective To investigate the effect of three kinds of low molecular weight heparin combined with methylprednisolone on the high coagulation state and renal function in patients with refractory nephrotic syndrome.Methods 140 cases of refractory nephrotic syndrome were divided into four groups, 35 cases in each group.The control group were treated with methylprednisolone.Small, medium, and large dose group in the control group on the basis of the treatment, were given low molecular weight heparin on once every other day, once daily, twice daily treatment, 3075 AxaIU per times.The improvement of renal function and high coagulation state were compared between the four groups before and after treatment.In the course of treatment, the occurrence of adverse reactions was recorded.Results Remission rate in large, medium and small dose group remission rate was higher than the control group(χ2 =4.375,P<0.05); there was no significant difference in remission rate of three different dose groups.The 24h urine protein and ALB of the four groups after treatment were significantly increased, BUN and SCr were significantly lower(P<0.05).The 24h urine protein, ALB, BUN, SCr of improvement of large, medium and small dose group were significantly better than the control group( P<0.05).The 24 h urine protein, ALB, BUN, SCr in large dose group improved significantly better than those in small dose group(P<0.05).The APTT, PT in large, medium and small dose groups after treatment increased significantly, FIB decreased significantly(P<0.05).The improvement of FIB, APTT, PT in large, medium and small dose group were significantly better than the control group after treatment ( P <0.05 ).The FIB, APTT, PT in large dose group improved significantly better than those in medium and small dose group ( P <0.05 ) .Conclusion The low molecular weight heparin combined with methylprednisolone can significantly improve hypercoagulable state and renal function in the patients with refractory nephrotic syndrome, and the large dose of low molecular weight heparin effect is the best, and no significant adverse reactions occurred.

Objective To investigate the relation of synovial anti-citrullinated epitope peptide(CCP)expression and peptidyl arginine deiminase 4 (PADI4)gene in the rheumatoid arthritis patient.Methods From February 2013 to 2015 in Dongfeng General Hospital Affiliated to Hubei University,selected 110 patients with rheumatoid arthritis as the observation group, and selected 110 healthy people at the same period in this hospital for medical examination as the control group,both groups were given the synovial CCP expression positive rate and PADI4 gene expression detecting and correlation analysis.Results The synovial anti-CCP expression positive rates in the observation group and the control group were 70.9% and 9.1% re-spectively,and the observation group were significantly higher than the control group (P<0.05).The PADI4-104 genotype expression frequency compared between the observation group and control group,the difference were statistically significant (P<0.05).The G/G expression was more in the observation group,while the control group was more wit the C/G expres-sion.Pearson correlation analysis showed that in the observation group,synovial CCP positive expression were significant correlated to the expression of genotype PADI4-104 (r=0.344,P<0.05).Logistic regression analysis showed PADI4-104 genotype frequency were the main factors for the synovial CCP epitope expression (P<0.05).Conclusion The rheumatoid arthritis was more with synovial anti-CCP positive expression.There were also PADI4 polymorphism disorder expression, and clear correlation between the two.Thus impact the incidence of rheumatoid arthritis.
