ABSTRACT
It is of important significant to predict the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus infection in clinic. Various risks scoring systems can achieve better prediction effect by integrating a variety of risk factors, but they still need to be perfected. Recent researches have found that some genotypes and genetic variations are associated with the occurrence of HCC and they can indicate the tumorigenesis of HCC. Some known or newly discovered indicators such as WFA+ -M2BP can be used to predict the occurrence of HCC independently or jointly. With the development of research, more genes, indicators as well as newly built scoring system will be utilized to predict the occurrence of HCC in clinic.

ABSTRACT
Objective To investigate the medical assistance to inpatients from low-income families for solving their difficulties in seeing doctors and affordability.Methods Random sampling was made to five ongoing medical assistance projects in the hospital for statistics and analysis of the data so collected.Results Medical expenses of such inpatients are beyond their affordability.Despite the coverage of their basic medical insurance,the reimbursement rate is too low to alleviate their financial burden.Conclusion A“4-party payment”model is recommended,combining the government support for basic medical insurance,social welfare assistance,philanthropic assistance and that paid by the inpatients.This model is expected to effectively alleviate the financial burden of such inpatients.
ABSTRACT
Chronic and heavy alcohol consumption is one of the causes of heart diseases. However, the effects of ethanol on insulin sensitivity in myocardium has been unclear. To investigate the effects of ethanol on the expression of AMP-activated protein kinase (AMPK), myocyte enhancer factor 2 (MEF2) and glucose transporter 4 (GLUT4), all of which are involved in the regulation of insulin sensitivity, in the myocardium, we performed three parts of experiments in vivo and in vitro. I: Rats were injected with 5-amino-4-imidazolecarboxamide ribonucleotide (AICAR, 0.8 mg.kg(-1)) for 2 h. II: Rats received different dose (0.5, 2.5 or 5 g.kg(-1).d(-1)) of ethanol for 22-week. III: Primary neonatal rat cardiomyocytes were isolated and treated with or without 100 mM ethanol or 1 mM AICAR for 4 h. The cardiac protein and mRNA expression of AMPKalpha subunits, MEF2 and GLUT4 were observed by western-blotting and RT-PCR, respectively. Serum TNFalpha levels were assessed by ELISA. The results showed chronic ethanol exposure induced insulin resistance. Ethanol decreased the mRNA levels of AMPKalpha1 and alpha2, the protein levels of total- and phospho-AMPKalpha in cardiomyocytes. Similarly, ethanol showed inhibitory effects on both the mRNA and protein levels of MEF2A and 2D, and GLUT4 in a dose-response-like fashion. Correlation analysis implied an association between phospho-AMPKalpha and MEF2A or MEF2D, and between the levels of MEF2 protein and GLUT4 transcription. In addition, ethanol elevated serum TNFalpha level. Taken together, chronic ethanol exposure decreases the expression of AMPKalpha and MEF2, and is associated with GLUT4 decline in rat myocardium.

<p><b>OBJECTIVE</b>To explore the relationship between the alteration in GGT mRNA expression and the development of HCC.</p><p><b>METHODS</b>Three GGT mRNA types (F, H, and P) in normal liver tissues, diseased liver tissues without HCC, cancerous and noncancerous tissues from livers with HCC, and noncancerous tissues from livers with metastatic tumor were tested by RT-PCR.</p><p><b>RESULTS</b>In normal livers, the main type of GGT mRNA was type F. In liver diseases but not HCC, the distribution of the type GGT mRNA was nearly the same as in normal livers. The prevalence of type H was significantly higher in both cancerous and noncancerous tissues of livers with HCC than in livers without HCC (P<0.05). The prevalence of type F in cancerous tissues was significantly lower than that in livers without HCC (P<0.05).</p><p><b>CONCLUSIONS</b>The GGT mRNA expression in the human liver will shift from type F to type H during the development of HCC. The fragment analysis of GGT genes may be a sensitive assay to detect hepatic cell canceration.</p>

Purpose:To evaluate the feasibility, advantages and disadvantages of chemosensitivity test of human gastric cancer using MTT assay with short term culture tumor cells contaminated by nonmalignant cells compared with purifiedly primary culture tumor cells.Methods:Fifty nine fresh samples from patients with gastric cancer were obtained from operating rooms. Chemosensitivity results were provided by the MTT assay with short term culture cells. The primary culture cells were purified by means of a series of methods such as repeated cell attachment, differential trypsinization and natural purification which removed fibroblasts and other nonmalignant cells. The same MTT assay was conducted using purified cells. Chemosensitivity results between short term method and purification method were compared for seven antitumor drugs. Results:The success rate of short term method using the MTT assay for chemosensitivity testing was 81 4% (48 of 59 patients),and for the purification method it was 50.8(30 of 59 patients). The average was 20.2?9.5 days when primary cells were cultured into purified cancer cells. The optical density ( A ) value correlated directly with the the number of tumor cells with the two methods( P
ABSTRACT
Objective:To investigate the role of soluble Fas ligand (sFasL) in the mechanism of immune escape and counterattack of colorectal cancer.Methods:ELISA was used to detect the level of sFasL in the sera of colorectal cancer patients and the supernatant of SW480. Transmission electron microscopy (TEM), flow cytometry (FCM) analysis and fluorescence microscopy were used to examine the apoptosis of Jurkat induced by the sera of colorectal cancer patients and the supernatant of SW480. The apoptosis was also studied after pretreatment of Jurkat by Fas blocking antibody ZB4. The supernatant of African green monkey cell line Vero was used as control.Results:The concentration of sFasL in sera of colorectal cancer patients was 12.21?1.14 ?g/L before treatment, the concentration decreased significantly after treatment(P
ABSTRACT
OBJECTIVE To investigate the incidence of nosocomial infection in ICU patients and its risk factors to take measures to prevent from infection. METHODS The nosocomial infection of ICU patients in 12 hospitals from Oct to Dec 2007 using the method of target monitoring was investigated. The nosocomial infection rate was regalated by the method of ASA. The invasive procedure and the associated infection rate were analyzed. RESULTS Among 2087 inpatients in ICU,236 suffered from nosocomial infection,The nosocomial infection incidence was 11.31%,and the nosocomial infection rate per day was 2.38% after regulated by the method of ASA. The patient incidence of nosocomial infection was 3.57%,and the nosocomial infection rate per day was 0.67%. CONCLUSIONS The patients in ICU are susceptible population of nosocomial infection,target monitoring in ICU is an effective surveillance method to reduce the prevalence of nosocomial infection.
