Quality of life and its influencing factors in patients with post-traumatic epilepsy / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To observe the quality of life in patients with post-traumatic epilepsy and discuss the influencing factors.</p><p><b>METHODS</b>We assessed 105 patients with post-traumatic epilepsy and 100 healthy people as control using Quality of Life Scale-31 (QOL-31), Self-rating Depressing Scale (SDS) and Self-rating Anxiety Scale (SAS), and conducted retrospective analysis on the depression, anxiety, site of trauma, control of seizure, EEG and therapeutic compliance.</p><p><b>RESULTS</b>Patients with post-traumatic epilepsy scored much lower than the control group on QOL-31 (P less than 0.01), but higher than the control group on SDS and SAS (P less than 0.01). Multiple regression analysis indicated that major influencing factors on the quality of life were anxiety, therapeutic compliance, depression, poor control of epileptic seizure and site of trauma.</p><p><b>CONCLUSIONS</b>The quality of life in patients with post-traumatic epilepsy has significantly declined. Doctors should pay attention to psychological and mental problems of patients with epilepsy, such as depression and anxiety, enhancing therapeutic compliance and controlling epileptic seizure, which are the keys to improving prognosis.</p>

Expression of LOX and MMP-2 in gastric cancer tissue and the effects of LOX and MMP-2 on tumor invasion and metastasis / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To compare the expressions of lysyl oxidase (LOX) and matrix metalloproteinases-2 (MMP-2) in gastric cancer and pericancerous tissues, in gastric cancers with and without lymph node metastasis, and to analyze the effects of LOX and MMP-2 on tumor invasion and metastasis.</p><p><b>METHODS</b>Gastric cancer and pericancerous tissues were collected from 46 patients who underwent surgery. Levels of LOX and MMP-2 mRNA were detected by RT-PCR. Protein abundance of LOX and MMP-2 was examined using Western blot.</p><p><b>RESULTS</b>Expressions of LOX and MMP-2 mRNA, and protein in 46 gastric cancers were significantly higher than that in 46 pericancerous tissues. In gastric cancer with lymph node metastasis, the levels of LOX and MMP-2 mRNA and protein were higher than those in gastric cancers without lymph node metastasis (P < 0.05). In the groups of gastric cancer with lymph node metastasis, expression of LOX was positively correlated with MMP-2 protein expression (P < 0.01).</p><p><b>CONCLUSIONS</b>Expressions of LOX and MMP-2 in gastric cancer tissues are significantly higher than that in pericancerous tissues. The expressions of LOX and MMP-2 in gastric cancer with lymph node metastasis are higher than that in gastric cancer without lymph node metastasis. Expressions of LOX and MMP-2 are positively correlated. The results suggest that LOX and MMP-2 may promote the growth and metastasis of gastric cancer.</p>

Effect of lysyl oxidase on migration and adhesion of human gastric cancer HGC-27 cells in vitro / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To study the effects of lysyl oxidase (LOX) on the migration and adhesion of the human gastric cancer cell line HGC-27 cells in vitro.</p><p><b>METHODS</b>The human gastric cancer cell line HGC-27 cells were cultured in vitro, and treated with different concentration of β-aminopropionitrile (BAPN). The ability of migration was assessed by wound-healing assay. The ability of adhesion was detected by homogenous and heterogeneous adhesion experiments.</p><p><b>RESULTS</b>Compared that with 0 mmol/L BAPN, the ability of migration of the cells after treatment with 0.2 mmol/L BAPN was descended at 8, 24, 32 and 48 h; the number of cells with homogeneous adhesion was increased from (6.97 ± 0.07) × 10(3)/ml to (7.78 ± 0.11) × 10(3)/ml; and the number of cells with heterogeneous adhesion was decreased from (8.98 ± 0.15) × 10(3)/ml to (8.35 ± 0.10) × 10(3)/ml, both < 0.05. Compared with that of cells treated with 0 mmol/L and 0.2 mmol/L BAPN, the migration ability of cells after treatment with 0.3 mmol/L BAPN was descended at 8, 24, 32 and 48 h; the number of cells with homogeneous adhesion was raised to (8.02 ± 0.11) × 10(3)/ml and the number of cells with heterogeneous adhesion was down to (7.93 ± 0.07) × 10(3)/ml (P < 0.05).</p><p><b>CONCLUSION</b>LOX may promote the metastasis of cancer cells by enhancing invasion, increasing heterogeneous adhesion and decreasing homogeneous adhesion.</p>
