Liver and gastrointestinal tumors greatly threaten human health and have poor therapeutic outcomes and prognosis.Tumor necrosis factor -alpha -induced protein 8 -like 2 (TIPE2)can negatively regulate innate immunity and adaptive immunity and maintain immune ho-meostasis.Recent studies have found that TIPE2 can affect various signaling pathways and thus exerts an inhibitory effect on the development and progression of tumors.This article briefly introduces the structure and function of TIPE2 and its regulatory effect on tumor -related sig-naling pathways such as Ras,Ral,and Rac and downstream molecules,as well as the role of TIPE2 in liver and gastrointestinal tumors,re-lated signaling pathways,and research advances.

In this study, optical data on color of tongue tips were collected by using a visible reflection spectrum system. Quantitative method of tongue inspection and classification of tongue states including pale, pale red, red and crimson manifestations were investigated.

Objective To investigate the efficacy of transplantation of induced bone marrow mesenchymal stem cells(MSCs)via various route for treatment of chronic liver injury.Methods MSCs were isolated and expanded by density gradient centrifugation combined with adherent culture.MSCs were induced to differentiate into hepatocyte-like cells in vitro.The markers of hepatocyte lineage were examined by RT-PCR and immunocytochemistry.The changes of ultramicrostructure of MSCs were observed by transmission electron microscope.One hundred and fourteen Wistar rats were treated with mixture of 40%CCl4 and peanut oil to establish chronic liver injury model and another 6 rats were served as control.Twelve rats in model group were died within 8 weeks,and the rest rats were divided into portal vein,spleen and tail vein transplantation groups.The rats were transplanted with DAPI-labelled MSCs which were induced for 14 days.The distribution of the DAPI-labelled cells were observed by fluorescence microscopy.The liver function and pathology were examined.Results AFP mRNA expression were detected at 7th and 14th day after induction,expressions of ALB mRNA,CK18 and hepatocyte antigen were found at 14th and 2lth day.The ultrastructure examination revealed that MSCs were enlarged with a lot of endoplasmic reticulum,mitochondrion,lysosome and glycogen granule.DAPI labelled cells were found in the spleen and liver transplantion groups.The pathological changes of liver were alleviated in all treated groups,especially in intraspleenic transplantion group(P＜0.05).Conclusions Induced bone marrow MSCs can ameliorate liver function of chronic hepatic injury after transplantation.The intraspleenic transplantation is better than others.

Objective To investigate the effect of noninvasive ventilator therapy on serum C-reactive protein (CRP), endothelin-1 (ET-1) and tumor necrosis factor-α (TNF-α) levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and its clinical significance. Methods One hundred cases of moder-ate and severe OSAHS patients were selected by the method of parallel opening. All of the patients were given health education requirement , quitting smoking and wine , low fat diet and exercise to lose weight and other con-ventional treatment. The patients were randomly divided into the treatment group of 42 cases with noninvasive ventilator treatment , 44 cases treated with conventional treatment , to observe the changes of serum CRP , ET-1 and TNF-α levels and PSG parameters after 12 weeks in two groups. Results Apnea hypopnea index (AHI), oxygen desaturation index (ODI), the lowest oxygen saturation (LSpO2), and the average oxygen saturation MSpO2 in OSAHS patients were significantly improved after treatment (P < 0.01), but the degree of improvement in the two groups after treatment was significantly higher than the control group (P < 0.01). Plasma CRP, ET-1 and TNF-α levels in the two groups after treatment were lower than before treatment (P < 0.05 or P < 0.01), but the treatment group was significantly higher than that of the control group ( P < 0 . 05 or P < 0 . 01 ) . Conclusion Noninvasive ventilator therapy in improving the OSAHS monitoring data of patients with PSG can effectively reduce the serum CRP, TNF-α, ET-1 level, reduce the body′s inflammatory reaction.

Objective To discuss the operative technique and curative effect of minor-incision cholecystectomy.Methods The clinical data of 672 patients with application of mini-cholecystectomy from June 2001 to June 2009 were analyzed.Perioperative management and operative technique were emphasized.Results Six hundred and fifty-two cases (97.0%) were cured with mini-cholecystectomy and 20 cases (3.0%) with incision lengthened.Operation time was (40.0?10.0) min.One case with hemorrhoea during operation was cured by interventional embolotherapy.Bile duct injury was found in 1 case during operation,and adopted suture with T tube.There were no infection of incisional wound or death in this study.Conclusion On the basis of skillful conventional cholecystectomy,by controlling indication and improving operative technique,it is an economical and safe way to perform minor-incision cholecystectomy.

Objective:To investigate the LOH at regions on chromosomal arm 8p22,11p15,17p13 and its relationship with clinicopathological parameters. Methods:Thirty-four paraffin-embedded tumor and corresponding noncancerous tissues were analysed. PCR was used to amplified three microsatellite markers D8S136,D11S988 and TP53 located at these chromosomal regions. PCR products were electrophoresed on 6%polyacrylamide gel and detected using silver staining. The P53, c-erBb-2,PR,ER status were determined by immunohistochemistry. Results:Of the three markers we studied, D8S136 was detected LOH at a frequency of 12 in 34 tumors(35.29%). D11S988 and TP53 were detected LOH at a frequency of 5 in 34 tumors(14.71%). There were no obvious associations between LOH at D11S988、TP53 and clinicopathological parameters, but the tumors with LOH at D8S136 were significant larger than that without LOH(P=0.0049). Conclusion: Invasive ductal carcinoma of the breast has a frequent LOH on chromosome 8p22. The loss or inactivation of putative tumor suppressor genes on 8p22 may contribute to the excessive growth of the tumors.

Linoleic acid (C18∶2n-6) and ?-linolenic acid (C18∶3n-3) are found widely in fungi, plants and some lower animals. However, they can not be synthesized in mammals due to lack of △12 and ?-3 fatty acid desaturases. To enable endogenous production of essential fatty acids in mammalian cells, here the stable expression of a Caenorhabditis elegans gene FAT-2 encoding △12 fatty acid desaturase in CHO cells was reported. First, the FAT-2 coding sequence was cloned by RT-PCR. To facilitate high level synthesis of heterogeneous protein, the codon usage of the fatty acid desaturase genes was optimized according to the codon preference of mouse by site-directed mutagenesis, 2 synonymous mutations were introduced into FAT-2 gene by overlapping PCR. The codon-modified gene was finally fused to pBudCE4.1 vector (Invitrogen) under the control of CMV promoter. The expression vector pBudCE-FAT2 was linearized with NheⅠ, and then transfected CHO cells, the cells were under Zeocin selection for nine days and then propagated, then the transfected cells were harvested. The genome and total RNA were isolated for PCR and Norhern blot ananlysis. The results revealed that FAT-2 gene has been integrated into the genome of CHO cells and expressed properly. Fatty acids of total cellular lipids were analyzed by gas chromatography. The results indicate that the expression and function of △-12 fatty acid desaturase resulted in accumulation of linoleic acid. The levels of linoleic acid in transgenic cells were 2.4-fold higher than those in wild-type cells. The moderate linoleic acid in CHO cells was derived from cell culture media uptaken by cell membrane. The results demonstrate that a heterogenous desaturase gene can function well in mammalian cells and prove that transgenic approach is an efficient strategy for changing fatty acid composition of mammals.
