AIM: To investigate the inhibitory effects of cholecystokinin octapeptide(CCK-8) on nuclear factor-?B(NF-?B) activities stimulated by lipopolysaccharide(LPS) by using forskolin,the activator of adenylate cyclase,and PKA inhibitor H-89 in rat pulmonary interstitial macrophages(PIMs).METHODS: PIMs were isolated and purified.EMDA was applied to detect NF-?B activities and Western blotting was used to analyze the I?B-? protein level in rat PIMs.RESULTS: The NF-?B activity was not detected in normal control rat PIMs.The NF-?B activity in LPS-treated rat PIMs was obviously higher than that in control group(P0.05).The NF-?B activity in CCK+LPS group and LPS+Fsk group were obviously lower than that in LPS group(P

To explore the cell adhesion molecules (CAMs) CD11a and CD49d in patients with chronic aplastic anemia (CAA) and its clinical implications, the expression of CD11a and CD49d in mononuclear cell (MNC) of bone marrow (BM) and peripheral blood (PB) were measured using APAAP techniques in 20 patients with CAA before and after SSL/C therapy. The results showed that the expression of CD11a and CD49d in MNC of BM and CD11a in MNC of PB increased significantly (P < 0.05) after SSL/C therapy, and there was no significant change of CD49d in MNC of PB in both groups. In conclusion, the decrease of CAMs of CD11a and CD49d participated in the pathogenesis of CAA. The expression of CAMs increases with effective treatment, so the restoration or improvement of altered CAMs of CAA might be beneficial to the proliferation and differentiation of hematopoietic stem cell, and improvement of hematopoiesis in CAA.

Objective To investigate the role of rotational alignment reference landmarks of the proximal tibia in total knee arthroplasty.Methods Fifteen healthy adult volunteers were enrolled in this study,including 10 males and 5 females,aged from 21 to 38 years (average,28.1±6.0).CT scans of 26 knees were taken as the knees were placed in full extension.Two anteroposterior axes were drawn on the CT images:one line connected the middle of the posterior cruciate ligament insertion site and the medial edge of the patellar tendon,and another line connected the middle of the posterior cruciate ligament insertion site and the middle-medial 1/3 of the patellar tendon.The surgical epicondylar axis was also drawn on the CT images.Angles were measured between a line perpendicular to the surgical epicondylar axis and the two anteroposterior axes,and the angles were compared with the ideal tibial rotational alignment reference axis (0°).Results Angles between the line perpendicular to the surgical epicondylar axis and the line connecting the middle of the posterior cruciate ligament insertion site and the medial edge of the patellar tendon averaged 0.7°±2.8° (range,-5.1°-5.8°),there was no significant difference compared with 0°.Angles between the line perpendicular to the surgical epicondylar axis and the line connecting the middle of the posterior cruciate ligament insertion site and the middle-medial 1/3 of the patellar tendon averaged 6.9°±5.3° (range,-3.4°-14.1°),there was significant difference compared with 0°.Significant difference existed in angles between the two anteroposterior axes and the line perpendicular to the surgical epicondylar axis.Conclusion The line connecting the middle of the posterior cruciate ligament insertion site and the medial edge of the patellar tendon is a more reliable reference axis for the tibial component rotational alignment,which makes the femoral and tibial components in a more matching rotational position.

Objective To compare the diagnostic efficiency between blastomere preimplantation genetic diagnosis (PGD) and polar body PGD for chromosomal translocation carriers. Methods Group A had 8 cycles using whole painting probes for the first polar body diagnosis, while group B had 29 cycles using two subtelomeric probes and one centromeric probe for the blastomere diagnosis. Results The fertilization rate of group A was significantly lower than group B [66. 1% (72/109) vs 85.2% (304/357) , P < 0.05]. There was no significant difference in the successful biopsy rate between two groups. However, group A had a significantly higher loss rate during fixation and higher no signal rate after fluorescence in situ hybridization [ FISH, 9. 6% (12/104) vs 1.6% (4/252), 11.2% (10/89) vs 3.0% (7/233) ]. Totally, the diagnostic efficiency in group A (72. 5% ,79/109 ) was significantly lower than that in group B( 89. 8%, 230/256, P < 0. 05 ). Although both the clinical pregnancy rate( 3/7 ) and implantation rate( 22. 2% ,4/18 ) of group A were higher, the differences were not statistically significant ( P > 0.05 ). Conclusion Both methods can be used efficiently in the PGD for chromosomal translocation carriers. Blastomere PGD has a higher diagnostic rate.

0.99). DC: reproducibility was good for neutrophils, lymphocytes monocytes, eosinophils and basophils. Comparison of the results by instrument with manual for normal samples in morphology, the correlation was better for neutrophils, lymphocytes and eosinophils (r:0.968～0.983) ,good for monocytes(r=0.917), not good for basophils(r=0.659);The WBC scattergram would change and alarm flags would display when there are neutrophilic stab granulocytes, abnormal or atypical lymphocytes and immature cells in higher proportion.Conclusions The analyzer can be used to test blood cell parameters accurately and reliably. Its main performance indices accorded with the experimental requirements; The results were credible. It is necessary to check with microscopy for DC before reported when it were doubtted.

Objective To analyze the relationship between biochemical level and severity levels and clinical,duration of disease in patients with Parkinson Disease (PD).Methods 69 patients with PD and 69 healthy persons of similar sex and age were selected in the research.Serum uric acid and lipids levels were examined and compared.Results The serum uric acid,triglycerides,total cholesterol and low-density lipoprotein cholesterol (LDL-C) were (322.48 ± 66.18) μmol/L,(1.22 ± 0.86) mmol/L,(4.70 ± 0.92) mmol/L and (3.00 ± 0.85) mmol/L in control group,and (384.23 ± 88.28) μmol/L、(1.64 ± 0.94) mmol/L、(5.37 ± 1.31) mmol/L、(3.53 ± 1.03) mmol/L in control group.The differences are significant (t =-4.68,P =0.000;t =-2.74,P =0.007;t =-2.74,P =0.007;t =-3.49,P =0.001;t =-3.27,P =0.001).Serum UA concentration and high-density lipoprotein cholesterol (HDL-C),LDL-C were lower in patients with Parkinson's disease in duration of disease more than 3 years than those in duration of disease less than 3 years (t =3.373,P =0.001;t =2.440,P =0.017).The serum UA levels of any stages of PD patients were lower than the control group (P ＜ 0.05) according to Hoehn-Yahr staging.All lipid levels in early and middle stage PD disease patients were lower than those in control group (P ＜ 0.05).Serum UA,total cholesterol and HDL-C in female PD patients were (305.69 ± 54.25) μmol/L,(4.99 ± 0.95) mmol/L,(1.25 ± 0.27) mmol/L,and (339.76 ± 73.40) μmol/L,(4.41 ± 0.81) mmol/L,(1.06 ± 0.19) mmol/L in male patients.The difference is significant (t =2.198,P =0.031;t =-2.721,P =0.008;t =-3.266,P =0.002).Multivariate logistic regression models assessed lower uric acid concentrations is the risk of PD (OR =1.01,95％ CI 1.004 ～ 1.015,P =0.001).Conclusion Biochemical level changed differently in Parkinson disease and uric acid reduction could be a risk factor for PD.
