Hypoxia inducible factor (HIF-1α) is a hypoxia response regulator,which is highly expressed in malignant tumors.Researches have shown that HIF-1α plays an important role in epithelial mesenchymal transformation.It can regulate epithelial mesenchymal transition through a series of signal pathways and mechanisms at many levels,to participate in the invasion and metastasis of tumors.To explore the mechanism of HIF-lα controlling epithelial mesenchymal transformation has important significance for the development of new,effective tumor treatment methods.

Vasculogenic mimicry (VM) can promote tumor growth, invasion, and metastasis. The formation of VM is regulated by various proteins including epithelial cell kinase, phosphoinositide-3 kinase, and hypoxia-inducible factor 1. Local microenvironment also plays an important role in regulating VM formation.

Objective To explore the factors related to the prognosis and survival duration of primary liver cancer patients after hepatectomy.Methods The data of primary liver cancer patientswho were treated by surgical resection were analyzed retrospectively.Kaplain-Meier method was used to evaluate survival rates.Log-rank test and Cox regression analysis were used to screen out related clinical phathology factors.Results The median survival time was eighteen months.Univarivate analysis showed that liver function Child-Pugh classification,cirrhosis,tumor size,HBV infection,AFP,portal vein tumor thrombus significantly correlated with survival rates (P ＜ 0.05).Multivariate analysis showed that liver function Child-Pugh classification,tumor size,AFP and portal vein tumor thrombus were the independent prognostic factors of primary liver cancer (P ＜ 0.05).Conclusion Many factors are related to the prognosis of primary liver cancer after operation.Liver function Child-Pugh classification,tumor size,AFP and portal vein tumor thrombus affect prognostic independently.

Objective To observe the effect of high-dose three-dimensional conformal radiotherapy (3DCRT) on recurrence and metastasiscervical cancer.Methods Sixty-one recurrence or metastasis cervical cancer patients were divided into two groups.Group high-dose 3DCRT (high-dose group) received radiotherapy using 6 MV X ray 4-8 Gy per field,three times per week,with total dose of 35-50 Gy.The other group (other group) received radiotherapy using 6 MV X ray 2 Gy per field,5 times per week,with total dose 40-60 Gy.The short-term efficacy and complications between the two groups were compared.Results The tumor regression rates of the two groups were 76.7 ％ (23/30) and 67.7 ％ (21/31) (x2 =0.604,P ＞ 0.05),which had no significant difference.The 1-year survival rates [63.3 ％ (19/30),54.8 ％ (17/31)] (x2 =0.454,P ＞ 0.05)and the 2-year survival rates [26.7 ％ (8/30),29 ％ (9/31)] (x2 =0.042,P ＞ 0.05) had no significant difference either,but in high-dose group,the bone marrow inhibition rate [53.3 ％ (16/30)] was significantly lower than other group [77.4 ％ (24/31)] (x2 =3.91,P ＜ 0.05),the reaction of digestive tract [56.7 ％ (12/30)] was also significantly lower than other group [56.7 ％ (12/30)] (x2 =4.09,P ＜ 0.05).Conclusion Compared with the other group,the high-dose 3DCRT has the same short-term efficacy but lower short-complications,and the quantity of life is better than the other group.

Objective To observe the adipose-derived cytokine changes and aggravate cognitive impairment in olanzapine-induced obese rats caused by glucose metabolic disorder.Methods 20 rats fed with ordinary fodder were used as normal control group,olanzapine group of 20 rats fed with olanzapine(1.2 mg · kg-1) and ordinary fodder for 4 weeks.Successfully established experimental model rats induced by olanzapine after 4 weeks.Serum tumor necrosis factor α(TNF-α),interleukins 6 (IL-6) and C-reactive protein (CRP) contents were measured by Elisa.Serum glucose contents were determined by biochemical colorimetric method and blood lipid contents determined with automatic biochemical analyzer.Learning,memory capacity and escape latency were detected with Maze test.Results After administration 4 weeks,the levels of body weight,blood glucose and blood lipid in olanzapine group were higher than those in control group.The serum TNF-α((1.57±0.04) ng/ml),IL-6((127.47±11.38) pg/ml) and CRP ((2.68±0.06) mg/ml) in olanzapine group rised,compared with control group ((0.59±0.03) ng/ml,(96.58± 8.77) pg/ml and (1.86±0.04) mg/ml respectively),the differences were statistically significant(P＜0.05).Electric shocks and escape latency in olanzapine group were higher than those in control group (P＜0.05).The FBS had positive correlation with hs-CRP,IL-6 and TNF-α respectively (r=0.385,0.260,1.280; all P＜0.05).Conclusion Olanzapine can induce metabolic disturbance of blood glucose,blood hpid,and the increase of serum TNF-α,IL-6 and CRP levels in rats.Positive correlation is showed between TNF-of and FBS.Hyperglycemia can promote cell toxicity and leads to cognitive dysfunction in rats.

Objective To detect the physical and psychological function of traditional Chinese emotional nursing versus normal nursing on coronary heart disease patients. Methods Searching the major clinical databases of Cochrane library, PubMed, China National Knowledge Infrastructure, Wanfang database and VIP database to collect the relevant randomized controlled trial (RCT) about routine nursing combined with traditional Chinese medicine emotion care on coronary heart disease. After study selection, assessment and data extraction for RCT according to the inclusion and exclusion criteria, Meta-analysis were performed by using the RevMan5.2 software. Results Fourteen relevant studies as much as 1 164 patients were included in the study. Compared with the normal therapy, the figures support that the Chinese medicine emotional care group had a better curative effect (Z=6.74, P<0.01, OR=0.21, 95%CI:0.15-0.26), and the score of Hamilton Depression Scale (Z=8.84, P<0.01, MD=6.64, 95%CI:5.11-8.18), Self-Rating Depression Scale (Z=4.79, P<0.01, MD=8.21, 95%CI:4.89-11.66), and Self-Rating Anxiety Scale (Z=11.15, P < 0.01, MD=8.23, 95%CI:6.79-9.68) were all significantly decreased. Conclusions Compared to the conventional nursing combined with traditional Chinese emotional nursing and coronary heart diseaseroutine nursing care, the degree of depression and anxiety in patients is decreased significantly, and the total clinical efficacy is dramatically increased. However, the original study of quality constraints, muchmore high-quality, large sample of RCT is needed for further demonstration.

Objective To investigate the expression level of LMO1 in gastric cancer tissues and human gastric cancer cell lines,and explore the invasive and metastatic potential of LMO1 gene silencing by small interfering RNA on the human gastric cancer cell line MKN28.Methods Immunohistochemical technique was applied to detect the expression of LOM1 protein in gastric cancer tissues and tumor adjacent tissues of paraffin specimens in 30 cases.The expression levels of LMO1 in human gastric cancer cell lines AGS,BGC-823,SGC-7901,MKN28 and human gastric mucosal epithelial cells GES were detected by realtime-PCR and Western blot.Using LipofectamineTM 2000,LMO1 siRNA was transfected into MKN28 cellsin vitro (siRNA transfect group).Negative control was established.Real time-PCR and Western blot was used to examine the difference of LMO1 expression.Transwell assays were performed to identify the differences and changes of invasive and metastatic ability in gastric cancer cell line MKN28.Western blot was used to examine the expression levels of E-cadherin,MMP-9 and VEGF.Results Positive rate of LOM1 protein in gastric cancer tissues(77％)was higher than that in tumor adjacent tissues (17％) (x2 =21.70,P ＜ 0.01).Positive rate of Vavl protein was higher in lymphatic metastasis group than in non-lymphatic metastasis group(x2 =5.83,P =0.02).Compared with GES,the expression level of LMO1 increased significantly in gastric cancer cell lines,especially in MKN28 (P ＜ 0.01).The expression levels of LMO1 mRNA and protein in LMO1-siRNA transfected MKN28 cells were lower than the matched negative control cells (P ＜0.01).The invasive and metastatic potentials of LMO1-siRNA transfected MKN28 cellssignificantly decreased (t =-11.53,P ＜0.01;t =-10.68,P ＜0.01).The expression levels of E-cadherin were higher than the matched negative control cells;and MMP-9,VEGF protein in LMO1-siRNA transfected MKN28 cells were lower than the matched negative control cells (P ＜ 0.01).Conclusions LMO1 has higher expression level in gastric cancer tissues and some gastric cancer cell lines,and down-regulation of LMO1 can inhibit the invasion and metastasis ability of gastric cancer.
