ObjectiveTo provide a reference for the establishment and appliance of enzyme reference measurement of CK in China by comparing and analyzing the RELA results of CK in IFCC from 2006-2008. Methods The RELA samples of CK were measured according to the reference procedure for the measurement of catalytic activity concentration of CK (37 ℃) ,which had been published by IFCC. The EP5A2 protocol was used for evaluation of the imprecision and ERM was used for verification of the trueness. Results In RELA 2006, the result of sample A was (9. 896 ±0. 112) μkat/L, and the result of sample B was (4.953 ±0. 120) μkat/L. In RELA 2007, the result of sample A was (2.684 ±0.054)μkat/L, and the result of sample B was (8.798 μ0. 101) μkat/L. In RELA 2008, the result of sample A was (10. 523 ±0. 149) μkat/L,and the result of sample B was (10. 551 ±0. 141) μkat/L. The precision of the CK reference method in the year 2006 to 2008 was 0. 92%, 0. 86% and 0. 88% respectively, each of them is less than 1% and the results of ERMs were consistent with the certified value(1. 68 ± 0. 07)μkat/L,which verify the imprecision and accuracy of the reference method. Conclusions All of the results in the continuous three years were in the range of equivalence limits suggested by IFCC. The CK reference method suggested by IFCC has been established and it is getting better.

OBJECTIVE To investigate ?-lactamase coding genes and oprD2 gene in multidrug-resistant Pseudomonas aeruginosa isolated.METHODS Polymerase chain reaction(PCR) was used to detect various ?-lactamase coding genes including TEM,SHV,OXA,PER,GES,IMP,VIM,plasmid type AmpC ?-lactamase DHA,MIR and oprD2 in 20 strains of P.aeruginosa.RESULTS The detection rate of ?-lactamase coding genes plasmid type AmpC,VIM,TEM,SHV,OXA and IMP were 15%,5%,15%,10%,10% and 5%,respectively,the loss rate of oprD2 was 25%,but PER and GES genes were negative.CONCLUSIONS The study indicated that the P.aeruginosa is carrying genes of DHA,TEM,SHV,OXA,VIM,IMP and being lost oprD2 gene,the latter is the essential resistance mechanism of P.aeruginosa to beta-lactam antibiotics in local area.

Objective To explore the application and effects of bone lengthening growth diary in self management of patients after lower limb lengthening. Methods A total of 54 cases applying lower limb lengthening were divided into the experimental group (n=28) and the control group (n=26) with random digit table. The basic treatment was consistent, the control group was given routine guidance, the experi-mental group implemented self- management with bone lengthening growth diary. Self- recognition of disease was assessed and compared between the two groups 12 weeks after operation. Self- efficacy and self- manage ment were assessed and compared between the two groups 2 and 12 weeks after operation. Results The self- recognition of disease in the observation group was better than that of the control group, for patients with higher self- recognition degree (21 cases vs. 10 cases), χ2=8.64, P<0.05, the difference was significantly different. The total scores of self- efficacy and self- management in the observation group were higher than those of the control group,(48. 42±3.43) vs.(34.14±4.13),t=11.750, P<0.01;(55.35±2.69) vs.(42.15±3.67), t=15.130, P<0.01, the difference was significantly different. Conclusions Bone lengthening growth diary plays a beneficial role on self-management of patients with lower limb lengthening.

ObjectiveTo investigate the expression of Snail in bladder urothelial carcinoma and evaluate its relationship with E-cadherin and a subset of T cell groups.MethodsImmunohistochemical method was used to detect the expression of Snail and E-cadherin proteins in tissue from 156 cases of bladder urothelial carcinoma and 80 cases of the para-cancerous mucosa. The proteins expression status was analyzed with clinico-pathological data. Meanwhile, correlations with Snail and CD4+, CD8+, CD4+/CD8+ were analyzed.ResultsThe positive rate of Snail in bladder urothelial carcinoma was 65.4% , which was significantly higher than that in para-cancerous mucosa (48.8%). The expression of Snail was significantly correlated with the clinical stage, pathological grade, tumor quantity, distant metastasis and tumor recurrence.There was negative correlation between the expression of Snail and E-cadherin in bladder urothelial carcinoma. Positive expression of Snail had a negative correlation with the number of CD4+ and CD4+/CD8+ , whereas it had no significant correlation with the number of CD8+.ConclusionsBy inhibition of the E-cadherin expression and inducing local immunosuppression, Snail might play an important role in the process of the invasion and metastasis of bladder urothelial carcinoma.

Aim The expression of NF-?B activation and the effect of antioxidant (N- acetylcysteine, NAC) on NF-?B activity in human airway epithelial cell was assessed. Methods Using the TNF-?,the airway epithelial cell strains of normal subject(16HBE) and tumor patient (H292) was activated and using Western-Blot and ELISA the expression of NF-?B and IL-8 were detected. Results It was found that the activity of NF-?B could be stimulated by the TNF-? and increase with the amount of TNF-? with the peak occurring at 2 to 4 hours after stimulation and then decreasing at six hours. At the same time, the level of IL-8 was elevated, but decreased with inhibition of NF-?B activity by NAC, that means the action of NAC has a dose-dependent effect. Conclusion NAC not only blocks the signal transmission activated by NF-?B, but also anticipates the transcription modulation of expression of many cell factors and inflammatory mediums. It suggests that NAC may play a role in the anti-inflammatory treatment of respiratory diseases.

Objective:To delineate the G-banding-sug gested chromosome translocations by fluorescence in situ hybridization (FISH ) technique. Methods: Locus-specific probes, generated by degen erate oligonucleotide-primed PCR (DOP-PCR) technique from yeast artificial chr omosomes (YACs) mapping the regions in question, were used for FISH tests. Results: Among the 2 cases unresolved by G-banding, FISH confirm ed that one had a balanced translocation between chromosome 11 and chromosome 13 , the other had an unbalanced translocation between chromosome 6 and chromosome X.Conclusion: Because of its high sensitivity and specificity, FISH technique is a powerful adjunct to chromosome banding techniques, particula rly for the delineation of subtle chromosome rearrangement(s) and the origin of segment(s).
