Objective To understand the levels of plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) in cough variant asthma(CVA) patients, and to investigate their correlation and clinical implications. Methods Thirty CVA patients,30 typical bronchial asthma patients and 25 healthy controls were recruited. Three milliliter limosis venous blood were drawn from each patient to measure the levels of plasma ET and CGRP by radioimmanity. Results ①The levels of ET in the CVA group and typical bronchial asthma group were higher than that in healthy controls (P < 0.01). Their values were (103.58±28.66) ng/L, (129.37±27.28) ng/L and (72.63±21.52)ng/L, respectively. The levels of CGRP in the CVA group and typical bronchial asthma group were (7.62±2.56) ng/L and(6.63±2.09)ng/L The level of CGRP in the healthy controls group was (21.60±3.29) ng/L. The first two groups were lower than the latter(P < 0.01). However, there was no significant difference between the CVA group and typical bronchial asthma group(P >0.05). ②ET and CGRP were negatively correlated in both CVA group(r= -0.819,P<0.05) and typical bronchial asthma group(r= -0.738,P<0.05). Conclusions ET and CGRP were negatively correlated in both CVA group and typical bronchial asthma group, which means that ET and CGRP were a couple of antagonistic factors participated in the regulation of CVA, and may play an important role in the process of CVA.

Aim To explore the effects of the inhibition of cell adhesion , invasion and migration in non-small cell lung cancer ( NSCLC ) H460 and A549 cells in-duced by platycodin-D ( PD ) and its mechanism. Methods Cell adhesion assay, wound-healing assay and Transwell chamber migration assay were used to detect the ability of cell adhesion, migration and inva-sion. Regulation of MMP-2 and MMP-9 mRNA was de-termined by RT-PCR. Meanwhile, Western blot was performed to determine the expression levels of MMP-2/9 , its upstream related proteins of ERK signaling pathway and p-Akt. Results PD effectively inhibited the ability of cell adhesion, invasion and migration in H460 and A549 cells in a dose-dependent manner ( P<0. 05 ) . PD reduced the expression of MMP-2 and MMP-9 mRNA in H460 and A549 cells ( P<0. 01 );meanwhile, PD down-regulated the expression levels of MMP-2/9 , and inhibited the expression of its upstream proteins Ras, p-c-Raf, p-ERK 1/2 and p-Akt in a time- and dose-dependent manner. Conclusions PD inhibits cell adhesion, invasion and migration in NSCLC cells, and these effects are related to the down-regulation of the expression of MMP-2 and MMP-9 mR-NA and protein, and inhibition of its upstream expres-sion of ERK signaling pathway and p-Akt.

The sagittal and transverse diameters of spinal canal were measured from 344 cases including dry specimens,preserved vertebral colomns and X-ray films.Based on these data several conclusions have been drawn. (1)The morphology of spinal canal is consistent with the external feature of spinal cord. (2)The mean values of various measurement of cervical(C),thoracic(T),and lumbar(L)vertebrae of spinal canal in dry specimens are as follows: Transverse diameter(mm.) Sagittal diameter(mm.) C T L C T L Male 23.6 16.7 23.4 14.4 14.9 16.5 Eemale 23.1 16.1 22.4 13.7 14.2 16.0 (3)The mean values of measurement of spinal canal in X-ray films are as fol- lows: Transverse diameter(mm.) Sagittal diameter(mm.) L C L Male 27.8 16.5 19.8 Female 27.0 15.7 19.1 The data measured from X-ray films are approximately 20% larger than those from the actual specimens. (4)The ratio between the sagittal diameters of the cervical canal and vertebral body is 80～90% in male and 90～100% in female.The normal ratio between the products of sagittal and transverse diameters of the lumbar spinal canal and of the vertebral body is 1:4.Ratios lower than this value is considered to denote a diagnostic significance for spinal stenosis.
