BACKGROUNDUlcerative colitis (UC) is associated with differential expression of genes involved in inflammation and tissue remodeling. MicroRNA (miRNA) plays an important role in the pathogenesis of UC by regulating the gene expression at the post-transcriptional level and control crucial physiological processes. This study aimed to identify aquaporin 8 (AQP8) expression and its relationship with miRNA in UC patients.

METHODSHuman colon samples, in this study, were obtained from 20 patients with UC and 16 healthy subjects undergoing diagnostic colonoscopy at the Chinese People's Liberation Army General Hospital between December 2009 and June 2010. We screened different genes from UC tissues and healthy subjects using genome-wide microarray, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting. Regulation of gene expression by miRNAs was assessed by luciferase reporter construct assays and transfection of specific miRNA mimics and inhibitor.

RESULTSWe identified that 1596 genes were increased and 1301 genes were decreased in UC patients compared to healthy subjects. Among them, we focused on the analysis of AQP8 which was decreased three folds in UC tissues (P < 0.01). The expression of AQP8 mRNA and protein were decreased in UC tissue and tumor necrosis factor (TNF)-α treated HT29 cells compared with controls (P < 0.05). We searched candidate target miRNAs of AQP8 through bioformatics and the luciferase report assay analysis indicated that miR-424, miR-195, miR-330, miR-612, and miR-16 which has complementary site in the 3-untranslated region (3'UTR) of AQP8 could decrease the relative luciferase activities by 10% - 45%.

CONCLUSIONAQP8 and its relationship with miRNAs may be involved in the pathogenesis of UC.

BmNPV GD isolate from China was plaque-purified and four bro genes were cloned termed as bro-a,b,c,d. The obtained sequences were aligned to the related sequences in GenBank and the BmNPV CQ1 isolate preserved in our laboratory. Compared with genome sequences of BmNPV T3 isolate, bro genes of GD isolate housed insertion and deletion, and the changes of amino acid mainly occured at the N terminal of corresponding protein. The phylogenetic analysis of bro genes indicated that GD bro-d gene belongs to subgroup A together with T3, CQ1 bro-d and SC7 bro- III; GD bro-a, c genes belong to subgroup B together with T3, CQ1 bro-a, c and SC7 bro-II; GD bro-b gene belongs to subgroup C together with T3, CQ1 bro-b, e and SC7 bro-I. The evolutionary relationship of bro genes showed vague relevance to their geographical location. The distribution character of bro genes in four BmNPV isolates is coincidence with the KANG's theory that the bro-d plays an irreplaceable functional role(s) during viral replication, while bro-a and bro-c functionally complement each other. Meanwhile, we postulate that 3 bro genes in SC7 isolate is probable the most simple form of bro genes.

OBJECTIVETo evaluate the role of vascular resection and reconstruction in the treatment of hilar cholangiocarcinoma.

METHODS117 patients with potentially resectable hilar cholangiocarcinoma underwent exploration. Twenty-one patients had exploration or drainage only due to distant metastases, and the other 96 patients received surgical resection. Thirty-one of those had vascular resection and reconstruction, including portal vein resection alone in 21 patients, combined hepatic artery and portal vein resection in 2 and hepatic artery resection alone in 8. Therefore, the patients were divided into four groups: non-surgical resection (21), portal vain resection (21), hepatic artery resection (10) and non-vascular resection (65) and their clinical data were reviewed retrospectively.

RESULTSThe hepatic artery resection group had significantly higher perioperative morbidity and mortality rate (80.0% and 20.0%) than non-vascular resection group (16.9% and 1.5%), respectively, (P < 0.05), while no significant difference was found between the portal vein resection alone group and the non-vascular resection group (P > 0.05). Of all resected vessel specimens, vascular wall invasion beyond the adventitia was pathologically confirmed in 82.6% of the portal veins and 50.0% of the hepatic arteries. The 1-, 3- and 5-year survival rates were 59.0%, 34.0%, and 16.0% in the non-vascular resection group, versus 44.0%, 23.0% and 11.0% in the portal vein resection alone group (P < 0.05) and 18.0%, 0 and 0 in the hepatic artery resection group (P < 0.01), respectively, with a significant difference among the three groups. The 1-, 3- and 5-year survival rates in the non-surgical resection group were 13.0%, 0 and 0, respectively, which were similar to those in the hepatic artery resection group. Though a significant difference in survival rates existed between the portal vein resection alone group and non-resected group (P < 0.001), no significant difference was found between the hepatic artery resection group and non-resected group (P > 0.05).

CONCLUSIONBoth portal vein and hepatic artery resection can improve resection rate for hilar cholangiocarcinoma, and portal vein resection may improve the prognosis in selected patients. However, hepatic artery resection can not improve survival and may even lead to an increase of perioperative morbidity and mortality.

Objective To investigate the curative effect of YU Yun pulse-feeling-based acupuncture therapy for the treatment of middle-late liver cancer. Methods A total of 60 middle-late liver cancer patients were divided into control group and treatment group by stratified randomization method,30 cases in each group. The control group was given integrated Chinese and western medicine therapy according to the clinical pathway, including anti-cancer treatment such as vascular interrention,molecular targeted therapy,chemotherapy,radio therapy, and focal ablation therapy,as well as chinese medicine treatment based on disease differentiation and syndrome differentiation. And the treatment group was given YU Yun pulse-feeling-based acupuncture therapy on the basis of treatment for the control group. The two groups received 12-week treatment, and then their curative effects were compared. Results The treatment group had better effect on increasing the survival rate, prolonging survival time, improving the scores of clinical symptoms, stabilizing tumor size, and increasing the scores of Karnofsky Performance Status (KPS)than the control group,the difference being significant (P < 0.05 or P <0.01). Conclusion YU Yun pulse-feeling-based acupuncture therapy exerts certain curative effect for the treatment of middle-late liver cancer.

Objective To investigate the effect of recombinant human interleukin-2 (rhIL-2) activated natural killer cells (rhIL-2-NK) on angiogenesis and cardiac function of rats with myocardial infarction (MI).Methods Natural killer cells (NKs) were isolated and activated by rhIL-2 in vitro.Untreated NKs were used as the control,the killing capacity of rhIL-2-NK were evaluated with cytotoxicity assay.Cardiac microvascular endothelial cells (CMECs) were cocultured with rhIL-2-NK.One hour after MI,rats were randomly divided into rhIL-2-NK group,NK group and blank control group and NK,rhIL-2-NK and PBS were injected directly in the infracted myocardium.At the 0,1st,3rd,5th,7th and 20th day after MI,the mRNA expression of monocyte chemotactic protein-1 (MCP-1),Tumor necrosis factor-α (TNF-α) and interleukin-2 (IL-2) were was detected by q-PCR essay.At the end of the therapy,the platelet endothelial cell adhesion molecule-1 (CD31) and vascular endothelial growth factor (VEGF) were evaluated through immunohistochemical assay,and the cardiac function observed with echocardiography,homodynamic measurements.Results The NKs were isolated successfully and the CMEC were proliferated remarkably by coculturing with rhIL-2-NK (P ＜0.01).The mRNA expression of MCP-1,TNF-α,CD31 and rhIL-2,VEGF were significantly upregulated in rhIL-2-NK group than in the PBS control group (P ＜0.01).Four weeks after operation,LVEF was significantly higher in rhIL-2-NK group than in the PBS control group [(77.56 ± 15.67) ％ vs.(41.47 ± 12.21) ％,P ＜ 0.05)] and histomorphology assay revealed that the density of microvascular endothelial (MVD) of rhIL-2-NK group was significantly higher than that of PBS control group (17.35 ± 1.82 vs.4.76 ± 0.92,P ＜ 0.01).Conclusions Myocardial injection of rhIL-2-NK could promote angiogenesis and improve cardiac function in MI rats.

OBJECTIVETo study the three-dimensional (3D) reconstruction and 3D visualization of the pancreas and create anatomy of the digitalized visual pancreas so as to construct a concrete basis for virtual operation and surgical operation on pancreas.

METHODSThe digital imaging data of pancreas, duodenum, common bile duct, arteries and veins were obtained from the Virtual Chinese Human-Female 1 (VCH-F1) and processed using ACDSee and Photoshop so as to reconstruct 3D pancreas digitally and realize 3D visualization of pancreas.

RESULTSWe successfully 3D reconstructed and visualized the pancreas and the peri-pancreatic structures: the duodenum, the common bile duct, the inferior vena cava, the portal vein vessels, the aorta, the ceoliac trunk vessels. The 3D and visualized pancreas manifested itself with its complete structure as well as its adjacency to other tissues.

CONCLUSIONSThe 3D reconstruction and 3D visualization of the pancreas based on the digital data of VCH-F1 produces a digitally visualized pancreas, which promises us a novel method for virtual operation on pancreas, clinical operation on pancreas and anatomy of 3D visualized pancreas.
