Objective To find an ideal liver cirrhosis portal hypertension model in big animals suitable for surgical study.Methods Twenty canines were treated by subcutaneous injection of 60% CCl4 colza oil emulsion into the back,at a dose of 1.0-1.3 mL/kg every 10 days for a total of 6-8 times.At the same time,it was combined with the control of food intake.All canines were fed with rice mixed with 10% hog fat.The amount of rice was 15 g/kg per day from the first day to the forth day,but the amount of food was not controlled from the fifth day to the tenth day.During the process,the canines′ general condition was observed and the changes of hepatic functions such as ALT,TP,ALB,G and A/G were measured.The changes of liver morphology,the diameter and blood flow of portal vein were monitored with color Doppler.Every two weeks,a piece of hepatic tissue to observe the pathological change of liver was excised operatively.Results During the process,the body weight of the canines decreased continually;ALT increased during early and middle stages and decreased during advanced stage;TP and ALB always decreased,and A/G continuously decreased,but G did not change significamtly.Eight weeks after injection,liver became progressively smaller.its density was not well-distributed,and liver particles gradually became coarse,and liver capsule became rough.The diameter of portal veins became larger and the velocity of portal vein became slower.Liver cirrhosis with psudolobules was found on light microscopy from the tenth week to the twelfth week.Three canines died,with mortality of 15.0%.Conclusions It took 10-12 weeks to establish this liver cirrhosis portal hypertension models in canines by subcutaneous injection of CCl4.This method is convenient,has high success rate,and is suitable for use in surgieal research.

OBJECTIVETo examine the differential levels of fecal Bifidobacterium, Bacteroides, Eubacterium rectale-Clostridium, Escherichia coli, Enterococcus, and Clostridium difficile between patients with hepatic cirrhosis and healthy controls. Fecal samples were collected from 29 patients with hepatic cirrhosis treated in the Department of Digestive Diseases at Zunyi Hospital between March and December of 2010.

METHODSFecal samples were collected from 13 healthy college students for use as controls. All samples were assessed by pH measurement, bacterial culture for turbidity, fluorescence in situ hybridization, and laser scanning confocal microscopy. The t-test and rank correlation test were used to determine statistical significance of intergroup differences in each tested parameter.

RESULTSThe feces of patients with hepatic cirrhosis had higher pH than that of healthy controls (6.79+/-0.64 vs. 6.18+/-0.74, P less than 0.05). The bacterial turbidity was not significantly different between the feces of hepatic cirrhosis patients and healthy controls (1.15+/-0.59 vs. 1.39+/-1.01, P more than 0.05). The numbers of Bifidobacterium, Bacteroides, Eubacterium rectale-Clostridium, Escherichia coli, Enterococcus, and Clostridium difficile in feces of patients with hepatic cirrhosis were significantly lower than those of the controls (all P less than 0.01). No significant correlation was found between the number or ratio of bacteria species and the severity of hepatic cirrhosis (Child-Pugh scores; P more than 0.05).

CONCLUSIONThe total quantity of intestinal bacteria in patients with hepatic cirrhosis is not significantly different from that in healthy patients. However, the profile of intestinal bacteria is different, which may explain the increased pH of fecal samples from patients with hepatic cirrhosis, but the differential profile is not correlated to cirrhosis pathogenesis.

Natural killer T-cell lymphoma (NKTL) is a malignant neoplasm which usually involves the nasal cavity or paranasal sinuses, while an orbit origin is extremely rare. Here we report the clinical, radiological and histopathologic features of a patient with NKTL originating from the orbit. We analyzed the clinical and radiologic records in the whole course of the disease. We also reviewed the morphology and immunohistochemistry of the neoplasm biopsy, including the presence of CD56, CD3 and cytotoxic molecules. This case demonstrated that nasal-type NKTL with a poor prognosis can originate from the orbit.

Orthotopic liver transplantation has proven to be effective in the treatment of a variety of life-threatening liver diseases, however, the limitations of donated organs available and long-term immunosuppression provided an impetus for developing alternative therapies. Cell replacement strategies have been one major effective approach for overcoming the obstacles of organ transplantation in recent years. The exogenous cells should be able to proliferate and differentiate into mature hepatic cells after grafting. Use of mature hepatocytes is also hampered by limited tissue source and inability to proliferate and maintain the function for a long term in vitro. Embryonic stem cells are immortal and pluripotent and may provide a novel cell source for potential cell therapy. This review summarizes the mechanisms of controlling early liver development and hepatic differentiation of visceral endoderm in embryoid bodies, and provides an overview of diverse differentiation systems in vitro and in vivo that were applied to hepatic research in recent years. Several studies have demonstrated that ES cell-derived hepatocytes can incorporate into liver tissue and function in vivo , but a few of them have shown complete restoration of liver function after transplantation into mice with liver diseases. Further studies should be made to exploit efficient methods and clinical applications of hepatocytes derived from ES cells in the future. In addition to clinical transplantation for treatment of liver diseases, ES cells can provide a valuable tool for drug discovery applications and study on of molecular basis of hepatic differentiation.

This study was aimed to detect the methylation status of FHIT gene promoter region in the DNA from plasma of patients with myelodysplastic syndrome (MDS), and to investigate the demethylating effect of decitabine. Methylation-specific PCR method was used to detect the methylation status of FHIT gene promoter region in the DNA from plasma of 4 patients with MDS before and after treatment with decitabine plus semis CAG therapy (among them, 1 case of newly diagnosed MDS, 3 cases progressed into acute leukemia). The results indicated that 3 cases were found to have an increased methylation in the promoter region. After treatment with decitabine plus semis CAG, increased methylation was reversed in 2 cases. In 4 cases, 2 cases displayed clinical response. It is concluded that FHIT gene hypermethylation is associated with MDS pathogenesis. Decitabine has demethylating effect on the FHIT gene hypermethylation of plasma from MDS patients. Detecting the methylation status of FHIT gene in DNA from plasma may play a role in MDS auxiliary diagnosis or prognosis.

To investigate the mechanism and biologic effects of 37 nm magnetic nano FeOx powders (MNPs) on human hepatoma-bearing nude mice. 37 nm MNPs were prepared by coprecipitation methods and then injected into human hepatoma (Bel-7402) bearing-nude mice through the tail vein. After injection of MNPs, the mice were first exposed under static magnetic field and then treated under extremely low frequency altering-electric magnetic field directing to the tumor area. The migration and trafficking of MNPs were determined by MMR. Tumor growth was monitored with calipers every 5 days and tumor volume was calculated on the basis of three-dimensioned measurements. The apoptosis of tumor cells was analyzed by flow cytometry analysis. The expressions of apoptosis-associated proteins Bcl-2, Bax and HSP27 were determined using western-blot analysis. Static magnetic field could direct the migration and trafficking of MNPs to the tumor site with a higher ratio of 98.9%. Extremely Low Frequency Electric-Magnetic Field (EMF) treatment could inhibit the proliferation of tumor cells and prolong the survive time of tumor-bearing mice injected with MNPs. In addition, the survival time of tumor-bearing mice and percentages of prohibition on tumor cell growth were 27.4+/-0.7 days and 37.5+/-0.8% (F = 0.005, P is less than to 0.05), respectively. The results of flow cytometry analyses showed that about 18.1+/-0.6% (F = 0.030, P is less than to 0.05) of tumor cells were induced into early apoptosis. Furthermore, expressions of apoptosis-associated proteins Bcl-2 and Bax were significantly induced by MNPs under EMF treatment. The ratio of Bcl/Bax in both MNPs and EMF treatment group was 0.07+/-0.01, which was much lower than that of control group (0.23+/-0.02) (F = 0.016, P is less than to 0.05). Heat shock protein-27 (Hsp-27) was not significantly induced in different treatment groups. Injection of MNPs with EMF exposure on human hepatoma-bearing nude mice could significantly prolong the survival time, inhibit the tumor proliferation and growth, and induce tumor cells into apoptosis.

OBJECTIVETo establish a simple, sensitive, specific and less-costly method for detecting genotypes of TT virus (TTV).

METHODSTTV DNA was tested by nested polymerase chain reaction (nPCR) in sera from 180 patients with different types of viral hepatitis and 96 normal individuals in Beijing. TTV genotypes were determined in 40 sera collected from TTV DNA positive patients by heteroduplex mobility assay (HMA) and through sequencing.

RESULTSThe positive rates of TTV DNA in viral hepatitis patients and normal individuals were 22.2% (40/180) and 19.8% (19/96), respectively (chi(2) = 0.220, P = 0.639). TTV DNA positive rates of patients with hepatitis A, B, C, E and non-A to E were 20.0% (6/30), 16.7% (5/30), 23.3% (7/30), 36.7% (11/30) and 18.3% (11/60), respectively. Of 40 TTV DNA positive patients, 20 (50.0%) were TTV G1, 7 (17.5%) TTV G2, 10 (25.0%) coinfected with different genotypes of TTV, and 3 untyped by HMA. Twenty G1 and 7 G2 detected by HMA were confirmed by sequence analysis. Of 10 patients coinfected with different genotypes of TTV, 5 were G1 and G2, 2 G1 and G3, 1 G1 and G4, 1 G1 and G3, and 1 with G1, G2 and G3 coinfections.

CONCLUSIONHMA was recognized as simple, sensitive, specific and less-costly, thus could be used for genotyping of TTV.
