The viscoelastic properties of hepatocellular carcinoma (HCC) cells were measured by means of micropipette aspiration technique. Further,the authors studied the changes in viscoelastic coefficients by treating with colchicine and cytochalasin D. The results showed that the elastic coefficients of HCC cells were obviously higher than the corresponding value of hepatocytes. By treating with colchicine, the effects on viscoelastic properties of HCC cells were obviously different in ways and extents from those on viscoelastic properties of hepatocytes.,but the viscoelastic properties of hepatocytes by treated with cytochalasin D had the same trend of decreasing as those of HCC cells. These results represent the change in cytoskeleton structure and function among hepatocytes and HCC cells, this change might affect tumor cells invasion and metastasis.

Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P ＜0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P ＞0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.

Objective: To access the risk for smoking on morbidity of acute ST-segment elevation myocardial infarction (STEMI) at different gender and age population. Methods: A case-control study was conducted in 2026 STEMI patients and 2026 control subjects with matched gender and age (±2 years) in our hospital from 2010-01-14 to 2016-02-27. The relationship between smoking and STEMI morbidity was analyzed. Results: Smoking was an important risk factor for STEMI morbidity in male gender and it was negatively related to age, as STEMI in young male smokers (≤45 years): adjusted OR=7.000, 95% CI 4.235-11.570; in middle age male smokers (46-59 years):adjusted OR=5.296, 95% CI 3.904-7.185 and in elder male smokers (≥60 years): adjusted OR=4.686, 95% CI 2.860-4.751. Conclusion: Smoking is a major risk factor for STEMI morbidity, while it is different from age and gender; the young male smokers have the highest risk to suffer from STEMI.

Objective To examine whether the increase of carbon monoxide (CO) induced by oral methylene chloride (MC) administration in recipients before heart transplantation would protect heart grafts against isehemia/reperfusion (I/R) injury associated with transplantation and to explore the possible mechanism.Methods Inbred male Balb/c mice were used as donors and recipients to establish cervical heart transplantation model Recipients were treated with either MC (100 mg/kg or 500 mg/kg,per os)(group MC 100 mg,n=10;group MC 500 mg,n=12) or olive oil(0.15 ml,per os.group olive,n=10) 3 h prior to anesthesia.Age-matched norwlal mice served as controls (group N,n=5).The serum COHb and the CO content of myocardial tissue were measured at 0,1,3,6,12,24 h after oral MC administration.Half of recipients were killed at 3 and 24h after transplantation for senum or cardiac graft samples.The serum cTnI levels,the mRNA levels of TNF-α,IL-10,Bcl-2,Bax.the protein levels of NF-κB and the ultrastructures of myocardium were examined.Results As tompared with group olive.the serum COHb and tissue CO were increased significantly and peaked within 3 h in group MC 100 mg and group MC 500 mg.The serum cTnI levels in group MC 100 mg and group MC 500 mg were significantly decreased (P<0. 01 ), especially in group MC 500 mg. The increase of CO in recipients of group MC100 mg and group MC 500 mg significantly inhibited the proinflammatory gene expression of TNF-α mRNA and the pro-apoptotic gene expression of Bax mRNA (P<0. 01), and increased the anti-apoptotic gene expression of Bcl-2 mRNA (P<0. 01), but did not increase the anti-inflammatory gene expression of IL-10 mRNA (P>0. 05) in the heart grafts. As compared with group N, the myocardial NF-κB activation was increased significantly in group olive,group MC 100 mg and group MC 500 mg (P<0. 01 ), but there was no significant difference among the later three groups (P>0. 05). The myocardial ultrastructure was also alleviated significantly in group MC 100 mg and group MC 500 mg as compared with group N. Conclusion The increase of CO induced by MC in recipients suppresses pro-inflammatory and pro-apoptotic gene expression and efficiently ameliorates transplant-induced heart I/R injury. The possible mechanism does not seem to be associated with down-regulation of the NF-κB signaling pathway.
