Nitrites play multiple characteristic functions in invasion and metastasis of hepatic cancer cells, but the exact mechanism is not yet known. Cancer cells can maintain the malignant characteristics via clearance of excess mitochondria by mitophagy. The purpose of this article was to determine the roles of nitrite, reactive oxygen species (ROS) and hypoxia inducing factor 1 alpha (HIF-1 α) in mitophagy of hepatic cancer cells. After exposure of human hepatocellular carcinoma SMMC-7721 cells to a serial concentrations of sodium nitrite for 24 h under normal oxygen, the maximal cell vitality was increased by 16 mg x (-1) sodium nitrite. In addition, the potentials of migration and invasion for SMMC-7721 cells were increased significantly at the same time. Furthermore, sodium nitrite exposure displayed an increase of stress fibers, lamellipodum and perinuclear mitochondrial distribution by cell staining with Actin-Tracker Green and Mito-Tracker Red, which was reversed by N-acetylcysteine (NAC, a reactive oxygen scavenger). DCFH-DA staining with fluorescent microscopy showed that the intracellular level of ROS concentration was increased by the sodium nitrite treatment. LC3 immunostaining and Western blot results showed that sodium nitrite enhanced cell autophagy flux. Under the transmission electron microscopy (TEM), more autolysosomes formed after sodium nitrite treatment and NAC could prevent autophagosome degradation. RT-PCR results indicated that the expression levels of COX I and COXIV mRNA were decreased significantly after sodium nitrite treatment. Meanwhile, laser scanning confocal microscopy showed that sodium nitrite significantly reduced mitochondrial mass detected by Mito-Tracker Green staining. The expression levels of HIF-1α, Beclin-1 and Bnip3 (mitophagy marker molecular) increased remarkably after sodium nitrite treatment, which were reversed by NAC. Our results demonstrated that sodium nitrite (16 mg x L(-1)) increased the potentials of invasion and migration of hepatic cancer SMMC-7721 cells through induction of ROS and HIF-1α mediated mitophagy.

Objective To retrospectively analyze the effect of corticosteroids therapy for inflammatory bowel disease (IBD) at 1-month and 1-year. Methods Those who was diagnosed as Crohn's disease (CD, n=55) or ulcerative colitis (UC, n= 154) from 1998 to 2006 were investigated. The effect of corticosteroids was evaluated after one month and 1-year. The prognostic factors were calculated using Logistic regression analysis. Results The patients who received eortieosteroids therapy were 21 (38.2%) with CD and 20 (13.0%) with UC (2 cases withdrawn). In one month followe-up, the complete and partial remissions were found in 15 (71.4%) and 3 (14.3%) patients with CD, respectively, while there were 15 (83.3%) and 3 (16.7%) in patients UC, respectively. Only 3 (14.3%) patients with CD was no response. In one year follow up, 11 out of 21 (52.4%) patients with CD had prolonged response to corticosteroids, 6 (28.6%) were corticosteroid dependence, and 4 (19%) required surgery; whereas 11 out of 18 (61.1%) patients with UC had prolonged response, 3 (16.7%) were corticosteroid dependence, and 4 (22.2%) required surgery. Logistic regression analysis showed that serum albumin level was associated with efficacy of corticosteroids after one year (P= 0.027, OR: 1.320,95% CI: 1.032~1. 690). Conclusion The IBD patients who has response to initiating corticosteroids therapy will get shor-term remission. Its prognosis is related with serum albumin level.

OBJECTIVETo determine the diagnostic value of FibroTest (FT) for liver fibrosis in patients with chronic hepatitis B (CHB).

METHODSOne hundred and forty-two patients with CHB were tested for the following five indicators: alpha2-microglobulin (a2-MG), haptoglobin (Hp), gamma-glutarnyl peptidase (GGT), total bilirubin (TBIL), and apolipoprotein A1 (ApoA1). The resultant data, along with the age and sex of the patients, were put into an algorithm to compute the final results of the FT. During the same period of FT, all of the CHB patients underwent liver stiffness measurement by FibroScan (FS) as well as liver biopsy. Considering the liver biopsy as the gold standard, we determined receiver operating characteristic (ROC) curves at different endpoints. Calculation of the area under the ROC curves (AUROC) was performed to evaluate the diagnostic importance of FT, FS towards the treatment of liver fibrosis in patients with CHB.

RESULTSSignificant fibrosis (Scheuer score (S) more than or equal to 2) was predicted with an AUROC for FS, FT of 0.827 (0.753-0.900), 0.897 (0.844-0.949). Significant fibrosis (S more than or equal to 3) was predicted with an AUROC for FS, FT of 0.883 (0.818-0.949), 0.968 (0.932-1.00). Significant fibrosis (S=4) was predicted with an AUROC for FS, FT of 0.943 (0.893-0.993), 0.991 (0.973-1.00).

CONCLUSIONs FT is a novel tool that can be used to assess the degree of fibrosis in patients with CHB.

Objective: To establish a mouse hepatocellular carcinoma cell line that can produce mMIP-1α and to evaluate the possibility of cancer gene therapy by mMIP-1α. Methods: mMIP-1α cDNA was cloned into retrovirus vector pBabe puro and pBabe puro-mMIP-1α was constructed, then pBabe puro-mMIP-1α was used to transfect packaging cells, anti-puromycin cells was proliferated, the supernatant was used to infect hepa1-6, the anti-puromycin clone (hepa1-6 mMIP-1α) and hepa1-6 were analysed for the expression of mMIP-1α mRNA and protein by RT-PCR and immunohistochemistry respectively. The growth curve of hepa1-6 and hepa1-6 mMIP-1α was drawn. The chemotaxis of mMIP-1α produced by hepa1-6 mMIP-1α to mouse spleen cells was observed on agarose gel. C57B/L mouse was inoculated with the tumor cell and the tumorigenicity was studied. Results: Recombinant retrovirus vector pBabe puro-mMIP-1α with mMIP-1α cDNA was constructed. Hepa1-6 did not produce mMIP-1α mRNA and protein, while hepa1-6 mMIP-1α could produce mMIP-1α mRNA and protein. The growth curve of hepa1-6 and hepa1-6 mMIP-1α showed no difference. The chemotaxis of mMIP-1α produced by hepa1-6 mMIP-1α to mouse spleen cells was observed. The tumorigenicity was reduced. Conclusion: A mouse hepatocellular carcinoma Hepa1-6 mMIP-1α is established and mMIP-1α can affect the tumorigenecity of hepa1-6.

AIM To explore the effects of Sangtong alkaloids (total alkaloids and total flavones from Mori folium,STA) on the random blood glucose,starch tolerance and hepatic insulin resistance in db/db mice with type 2 diabetes mellitus.METHODS Eight-week-old db/db mice were divided into model group (normal saline),acarbose group (39 mg/kg) and Sangtong alkaloids groups (105,210 and 420 mg/kg),db/m mice were used as control group (normal saline).The mice were given by intragastric administration for one hundred days.The random blood glucose of mice was determined every ten days.The starch tolerance was determined in the 100th day,together with the determination of serum insulin level,insulin resistance index and insulin sensitivity index.Histopathology changes of pancreas were observed by HE staining.Protein expressions of P-IRS1,P-PI3 K,P-AKT and GLUT2 were detected by Western blot.RESULTS Sangtong alkaloids significantly decreased the random blood glucose,serum insulin level and insulin resistance index,and increased the insulin sensitivity index in db/db mice.Meanwhile,Sangtong alkaloids ameliorated the pancreas histopathological damage and up-regulated the protein expressions of P-IRS1,P-PI3K,P-AKT and GLUT2 in liver.CONCLUSION Sangtong alkaloids can decrease the random blood glucose and improve the insulin resistance of liver in db/db mice with type 2 diabetes mellitus,whose mechanism may be associated with the regulation of hepatic insulin signal pathway.
