Aim To investigate the changes in the ex-pression of WNK1 in spinal cord of a rat model with bone cancer pain. Methods Female SD rats, weig-hing 170 ~200 g, were randomly divided into three groups:normal control group (group C, n=3), sham operation group ( group S, n =3 ) and bone cancer pain group ( group BCP, n =24 ) . Group C was not given any treatment, and group S was injected into the bone marrow of left tibia with 5 μl PBS solution while group BCP with 5 μl WALKER 256 mammary gland cancer cell suspension (approximately 1 × 105 cells). Mechanical paw withdrawal threshold ( MWT ) was measured at d1 before inoculation ( baseline) and d3, 6,9,10,11,12 after inoculation. Group S and C were sacrificed at d 12 while group BCP at d 3 ,6 ,9 ,12 after inoculation and spinal cord ( L4~6 ) were removed at different time points for detection of WNK1 mRNA ex-pression by qRT-PCR and WNK1 protein expression by Western blot. Results Compared with group C and S,group BCP’ s MWT started to decrease since d 3 ( P<0. 05 ) . The mRNA expression of WNK1 in spinal cord was up-regulated(P<0. 05) from d 3 showing an increasing trend over time until d 9 ( peak ) and then down-regulated to d 12 ( P >0. 05 ) while the protein expression upregulated since d6 and also showed an in-creasing trend to d 12 ( P<0. 01 ) . Conclusion The expression of WNK1 in spinal cord of a rat model with bone cancer pain increased abnormally, which may be involved in the occurrence and maintenance of a rat model with bone cancer pain.

Objective: To investigate the effect of clopidogrel on antiplatelet therapy in patients with coronary artery disease (CAD) combining chronic kidney disease (CKD) in order to provide a medication reference in clinical practice. Methods: We retrospectively investigated 423 CAD patients with coronary angiography (CAG) conifrmed diagnosis in our hospital from 2014-01 to 2014-09. According to the value of eGFR, the patients were classiifed into 2 groups:CAD+ CKD- group,n=257 patients with eGFR ≥ 90 ml/(min?1.73 m2), including 182 male and 75 female at the mean age of (60.39 ± 11.09) years, and CAD+CKD+ group,n=166 patients with eGFR < 90 ml/(min?1.73 m2), including 107 male and 59 female at the mean age of (65.80 ± 10.84) years. The patients were treated either by aspirin 0.1 g/d with clopidogrel 75 mg/d for at least 7 days, or by PCI operation with the load of aspirin 0.3g and clopidogrel 300 mg. The thrombelastography was conducted to examine and compare the inhibitory rates of ADP receptor and arachidonic acid (AA) pathway in platelet between 2 groups. Results: The inhibitory rate of platelet ADP receptor in CAD+CKD- group (64.9 ± 27.2) % was higher than that in CAD+CKD+ group (56.6 ± 27.4) %,P=0.039. Based on clinical standard of platelet’s ADP and AA inhibitory rates, in CAD+CKD- group, there were 24/257 (9.4%) of patients only insensitive to clopidogrel, in comparison with 25 (9.7%) of patients only insensitive to aspirin,P=0.99. While in CAD+CKD+ group, there were 21/166 (12.7%) of patients only insensitive to clopidogrel, in comparison with 11 (6.6%) of patients only insensitive to aspirin,P= 0.045. Conclusion: Clopidogrel has decreased effect on anti-platelet therapy in CAD patients combining with CKD, such patients have reduced sensitivity to relevant medication.
