Aldehyde dehydrogenase 1 (ALDH1) isoform expression and potential clinical implications in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most prevalent and life-threatening malignancies worldwide. There are few diagnostic and prognostic biomarkers and druggable targets for HCC. Aldehyde dehydrogenase 1 (ALDH1) is a marker of stem cells in a variety of cancers, but the mRNA levels and prognostic value of ALDH1 isoforms in HCC patients remain unknown.

Genome-wide and differential proteomic analysis of hepatitis B virus and aflatoxin B1 related hepatocellular carcinoma in Guangxi, China.

Both hepatitis B virus (HBV) and aflatoxin B1 (AFB1) exposure can cause liver damage as well as increase the probability of hepatocellular carcinoma (HCC). To investigate the underlying genetic changes that may influence development of HCC associated with HBV infection and AFB1 exposure, HCC patients were subdivided into 4 groups depending upon HBV and AFB1 exposure status: (HBV(+)/AFB1(+), HBV(+)/AFB1(-), HBV(-)/AFB1(+), HBV(-)/AFB1(-)). Genetic abnormalities and protein expression profiles were analyzed by array-based comparative genomic hybridization and isobaric tagging for quantitation.

Individualized peri-operative fluid therapy facilitating early-phase recovery after liver transplantation.

Aim: To investigate the correlation between peri-operative fluid therapy and early-phase recovery after liver transplantation (LT) by retrospectively reviewing 102 consecutive recipients.

Methods: Based on whether or not the patients had pulmonary complications, the patients were categorized into non-pulmonary and pulmonary groups. Twenty-eight peri-operative variables were analyzed in both groups to screen for the factors related to the occurrence of early pulmonary complications.

Effect of perioperative fluid therapy on early phase prognosis after liver transplantation.

Background: Although liver transplantation (LT) has made rapid progress, early pulmonary complications still occur. More attention should be paid to fluid therapy that may be an important factor leading to these complications. It is necessary to investigate the correlation between intraoperative and postoperative fluid therapy and early pulmonary complications after LT, then attempt to provide a reasonable fluid therapy in the perioperative period.

Hepatitis B virus infection contributes to oxidative stress in a population exposed to aflatoxin B1 and high-risk for hepatocellular carcinoma.

Biomarkers of hepatitis B virus (HBV) infection, aflatoxin B1 (AFB1) exposure and oxidative stress were detected in 71 hepatocellular carcinoma (HCC) patients and 694 controls from southern China. Plasma level of AFB1-albumin-adducts (AAA) and protein carbonyl content (PCC) were significantly higher in the 71 HCC cases than in any age/gender matched HBV sero-status groups (p<0.001).

Evaluation of oxidative stress in a group of adolescents exposed to a high level of aflatoxin B1--a multi-center and multi-biomarker study.

The association between aflatoxin B1 (AFB1) exposure and oxidative stress was extensively examined in 84 adolescents from an area at high risk for hepatocellular carcinoma in China. Plasma level of aflatoxin B1-albumin adducts (AAAs) was associated with AFB1 excretion in urine (r = 0.394, P < 0.

Is correction for protein concentration appropriate for protein adduct dosimetry? Hypothesis and clues from an aflatoxin B1-exposed population.

Protein adducts are useful biomarkers for assessing exposure, metabolism and risk of carcinogens. Aflatoxin B1-albumin adducts (AAA) and protein carbonyl content (PCC) have long been used for assessing aflatoxin exposure and oxidative stress to proteins, and the quantitative data are almost exclusively expressed per mg protein. Given the large variation in protein concentrations in plasma among populations, this may not be the most appropriate method.

Associated factors in modulating aflatoxin B1-albumin adduct level in three Chinese populations.

To elucidate the potential factors modulating exposure to aflatoxin B1 (AFB1) in three Chinese populations, an epidemiologic study was conducted in Fusui County and Nanning City of Guangxi Province and Chengdu City of Sichuan Province. The incidence rates of hepatocelluar carcinoma (HCC) for males in these three regions were 92-97 per 100,000, 32-47 per 100,000, and 21 per 100,000, respectively. Eighty-nine residents from Fusui, 196 residents from Nanning, and 118 residents from Chengdu were screened for AFB1-albumin adduct (AAA) levels and hepatitis virus (HBV, HCV, HDV, HEV, and HGV) infections, as well as liver biochemistry (alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [ALP], y-glutamyl transpeptidase [GGT], 5'-nucleotidase, globulin [GLO], direct bilirubin, indirect bilirubin, and bile acid levels).

[Transfection with virus interleukin-10 to prolong murine heart allograft].

Objective: To prolong murine heart allograft by modifying hematopoietic stem cells with virus interleukin-10 (vIL-10).

Methods: The recombinant of murine stem cell virus (MSCVneo) vIL-10 was composed of MSCVneo and vIL-10 cDNA and transduced hematopoietic stem cells from CBA (H-2(K)) mice's bone marrow in vitro. The transduced hematopoietic stem cells were transplanted into a syngenic CBA (H-2(K)) mouse with lethal irradiation (900 rad) in the same day through penis vein.

Intestinal perforation after combined liver-kidney transplantation for a case of congenital polycystic disease.

Aim: To highlight the intestinal perforation (IP), an uncommon and catastrophic complication after combined liver-kidney transplantation.

Methods: Combined liver-kidney transplantation (LKTx) with left kidney excision and a cyst fenestration procedure on the right kidney were performed on a case of 46-year-old female with congenital polycystic disease (CPCD).

Results: Two sites of IP were noted 40-50 cm proximal to ileocecal area during emergent laparotomy 10 d postoperatively.

Clinical epidemiological study on intrahepatic cholelithiasis: analysis of 8585 cases.

Objective: To investigate the clinical epidemiology of intrahepatic cholelithiasis in Guangxi area, China.

Methods: 8585 cases of cholelithiasis proved by surgery in a period of 19 years were analyzed retrospectively. Data were collected and analyzed by computer software package PEMS.

Oxidative DNA damage in peripheral leukocytes and its association with expression and polymorphisms of hOGG1: a study of adolescents in a high risk region for hepatocellular carcinoma in China.

Aim: To study the oxidative DNA damage to adolescents of hepatocellular carcinoma (HCC) families in Guangxi Zhuang Autonomous Region, China.

Methods: Peripheral leukocytes' DNA 7, 8-dihydro-8-oxoguanine (8-oxoG) and repair enzyme hOGG1 were quantified by flow-cytometry. hOGG1-Cys326Ser single nucleotide polymorphism (SNP) was distinguished by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) assay.
