Objective To explore the effect of hypoxia on the in vitro invasion of lung carcinoma cells and its molecular basis. Methods Small cell lung carcinoma cells(H128) were exposed to hypoxia(5%O 2,5%CO 2,90%N 2) or anoxia(95%N 2,5%CO 2)condition for 48 hours. The invasive ability of the cancer cells was assayed with HABM-HEM model. The expression of E-cadherin and ? 1-integrin on the cells was also assayed by flow cytometry. Results Compared with normoxia group, the invasive ability of the cancer cells increased, the expression of E-cadherin decreased, and the expression of ? 1-integrin increased in hypoxia group. In anoxia group, the invasive ability and the expression of E-cadherin and ? 1-integrin all decreased compared with normoxia group. Conclusions Moderate hypoxia can down-regulate the expression of E-cadherin, up-regulate the expression of ? 1-integrin, and increase the invasion of carcinoma cells. But serious hypoxia can decrease the expression of adhesive molecules and the invasion of the cancer cells.

AIM: To investigate the effect of hypoxia on the invasion and migration of lung carcinoma cells. METHODS: Lung carcinoma cell H128 was exposed to normoxia (air, 5% CO 2), hypoxia (5% O 2,5% CO 2,90% N 2) or anoxia (95% N 2,5% CO 2) conditions for 48 hours. The migration ability of the cells was assayed by wound healing methods. The invasiveness ability was determined with HABM-HEM model. The cells exposed to hypoxia were inoculated under skin in nude mice, and then the growth of the tumor and the rate of metastasis to lymph node or lung were observed. The expression of E-cadherin and ?1-integrin on the cells were also assayed by flow cytometry. RESULTS: Compared with normoxic group, the invasiveness and migration in hypoxic group were increased. The rates of tumorgenesis and metastasis to lung in anoxic group were evidently decreased. The expression of E-cadherin was decreased, and the expression of ?1-integrin was increased in hypoxic group. In anoxia group, the invasiveness, migration, the expression of E-cadherin and ?1-integrin were all decreased. CONCLUSIONS: Moderate hypoxia down-regulated the expression of E-cadherin, up-regulated the expression of ?1-integrin, and increased the invasiveness and metastasis of carcinoma cells. Serious hypoxia decreased the expression of adhesive molecules, and the proliferation, invasiveness and migration were also decreased.

Objective To study the expression of neural cell adhesion molecule CD 56 in the human lung cancer and its pathological significance. Methods 59 paraffin imbedded specimens of lung cancers were collected and human small cell lung cancer H128 cell line was cultured.The CD 56 expression in the lung cancer tissues and H128 cells was detected by immunohistochemical method. Results The expression of CD 56 was positive in 35 of 43 NSLC specimens, and the other specimens showed weakly positive staining. All 19 cases of the SCLC specimens showed CD 56 positive staining, 12 specimens of which were strongly positive. There was a significant difference in CD 56 expression between the SCLC and NSCLC. CD 56 was extensively expressed in H128 cells. Conclusion CD 56 might be an ideal tumour marker for SCLC.

OBJECTIVE: To investigate the relationship between insulin-like growth factor-1 (IGF-1) in the serum and the vascular endothelial function in patients with hypercholesterolemia and the underlying mechanism. METHODS: We examined the flow-mediated arterial diastolic function (FMD), the levels of IGF-1, asymmetric dimethylarginine (ADMA), NO, and the activity of nitric oxide synthase (NOS) in the serum from 25 patients with hypercholesterolemia and from healthy controls. An endothelial cell injury model was established by incubation of the human umbical vein endothelial cells (HUVECs) with oxidized low-density lipoprotein (ox-LDL) for 24 hours. Cells were treated with IGF-1 30 min before ox-LDL treatment. The levels of ADMA, NOS, and NO in the cell supernatant, the activity of dimethylarginine dimethylamine hydrolase (DDAH) in the cell lysate were measured. Beta-galactosidase staining was used to assess the degree of endothelial cell senescence by calculating the senescence rate of cells. RESULTS: Compared with the control group, the FMD, the levels of IGF-1 and NO, and the activity of NOS in the serum from patients with hypercholesterolemia decreased significantly accompanied with a dramatic increase at ADMA level. Multiple linear regression analysis showed that the change in IGF-1 was positively correlated with FMD while the change in ADMA was negatively correlated with FMD. Compared with the control group, ox-LDL treatments significantly decreased the activities of DDAH and NOS, and the level of NO, accompanied with an increase in ADMA. Betagalactosidase staining showed that the senescence rate of cells increased in the ox-LDL group. The effect of ox-LDL on HUVECs was significantly attenuated at the presence of IGF-1. CONCLUSION The decrease in IGF-1 in the peripheral blood may contribute to vascular endothelial dysfunction in patients with hypercholesterolemia. IGF-1 can protect HUVECs against ox-LDL-induced senescence, which is likely involved in the regulation of DDAH/ADMA pathway.

Valproic acid is a first-line broad-spectrum antiepileptic drug, however, the pharmacokinetics of valproic acid are affected by many factors, such as heredity, drug combination and so on. So, how to realize the individualized dosing regimen of valproic acid has received much attention. Population pharmacokinetics combines classical pharmacokinetic principles and population statistical models to quantitatively evaluate the influence factor of drug concentration in the patient population. Thus, it can optimize characterization of the differences among individuals. This article reviews the researches about valproic acid in recent years, and summarizes the effect of the factors on the metabolism of valproic acid, such as drug combination and gene polymorphism. Additionally, focus on the latest research progress of individual administration of valproic acid under the guidance of population pharmacokinetics.

OBJECTIVETo study the effect of gypenosides on DMN-induced liver fibrosis in rats.

METHODA rat liver fibrosis model was established by injecting DMN intraperitoneally. Four weeks later, model rats were randomly devided into three groups: the model group, the gypenosides treated group (200 mg x kg(-1)) and the colchicine treated group (0.1 mg x kg(-1)), with 10 specimens for each group. After a 2-week treatment, following parameters were observed: (1) last body weight, weight ratio between liver and spleen; (2) content of liver hydroxyproline (Hyp); (3) activity of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (gamma-GT), content of albumin (Alb) and total bilirubin( TBiL) in serum; (4) liver pathology (Sirius red staining and HE staining); (5) activity of liver superoxide dismutase (SOD), glutathione reduced (GSH), glutathione peroxidase (GSH-Px) and content of liver maleic dialdehyde (MDA).

RESULTThere were classic liver cirrhosis pathological changes in model groups. Compared with the normal group, liver Hyp content, activity of serum ATL, AST, gamma-GT and content of serum TBiL, MDA of model groups significantly increased; content of serum Alb and liver GSH, activity of liver SOD and GSH-Px decreased significantly in model groups. In comparison with the model group, liver cirrhosis remarkable improved in the gypenosides group, content of liver Hyp reduced significantly (P < 0.01), which was equal to the colchicine group. Compared with the model group, liver function parameters improved markedly in the gypenosides group; liver SOD and GSH-Px activities significantly increased; MDA content reduced significantly (P < 0.05).

CONCLUSIONGypenosides shows an effect in treating DMN-induced liver fibrosis in rats.
