Oxidored-nitro domain-containing protein 1 expression is associated with the progression of hepatocellular carcinoma.

Hepatocarcinogenesis is a stepwise process during which multiple genes are altered. Understanding the molecular mechanisms that induce hepatocarcinogenesis may improve the screening, prevention and treatment of patients with hepatocellular carcinoma (HCC). In recent years, the oxidored-nitro domain-containing protein 1 (NOR1) gene has been identified to have an important role in the development of HCC experiments.

Therapeutic effects of acetylspiramycin and garlicin on cryptosporidiosis among drug users.

Cryptosporidiosis affects humans of all ages, particularly malnourished children and those with compromised immune systems such as HIV/AIDS. This study investigated the therapeutic effects of acetylspiramycin and garlicin on Cryptosporidium infection in institutionalized male drug users receiving rehabilitative treatment. Examination of stool specimens from 903 drug users via modified acid-fast bacilli staining resulted in 172 positive cases.

Phenolics from Bidens bipinnata and their amylase inhibitory properties.

A new chlorinated flavonoid, 3, 6, 8-trichloro-5, 7, 3', 4'-tetrahydroxyflavone (1), a new biscoumaric acid derivative, 4-O-(2″, 3″-O-diacetyl-6″-O-p-coumaroyl-β-D-glucopyranosyl)-p-coumaric acid (2), and 8, 3', 4'-trihydroxyflavone-7-O-β-D-glucopyranoside (3) together with twenty-four known compounds (4-27) were isolated from the whole plant of Bidens bipinnata. All chemical structures were established on the basis of UV-, MS- and NMR (¹H, ¹³C, ¹H-¹H COSY, HMQC and HMBC) spectroscopic data. Some of the isolated compounds were tested for the inhibition of α-amylase.

[Study on risk factors of early complications after surgery for schistosomal portal hypertension].

Objective: To explore the related factors of early complications after surgery for schistosomal portal hypertension, so as to provide a scientific basis for prevention of postoperative complications and development of perioperative prevention programe.

Methods: Case data of patients with schistosomal portal hypertension in Xiangyue Hospital affiliated to Hunan Institute of Parasitic Diseases from January, 2000 to September, 2009 were collected. With single factor analysis and relevant professional knowledge, related factors were analysed with logistic regression analysis.

The study of the combination detection of HPV-DNA and p16INK4a in cervical lesions.

The objective of this study is to detect the infection of human papillomavirus (HPV) and the expression of p16(INK4a) in cervical lesions and to investigate the interaction between hrHPV and p16(INK4a) for cervical lesions and its diagnostic efficiency. hrHPV-DNA was detected by the hybrid capture II (HC-II) system. Immunochemical method was used to detect the expression of p16(INK4a), and histopathologic test was performed to identify cervical lesions.

[Time trends and age-related characteristics of cardio-cerebrovascular deaths in Hunan].

Objective: To investigate the time trends and age-related characteristics of mortality and disease burden for cardiocerebrovascular diseases (CVD) in Hunan, China during three periods (1973-1975, 1990-1992 and 2004-2005).

Methods: The cardiocerebrovascular death data of Hunan residents were collected by three national retrospective sample surveys of death. Cause-specific mortality, proportion, years of potential life lost (YPLL) and associated indicators were identified in the population of Hunan in above mentioned three periods.

An analysis on the combination expression of HPV L1 capsid protein and p16INK4a in cervical lesions.

Human papillomavirus (HPV) infection in cervix is the most important reason for cervical cancer, but only 2% cervical HPV infection will develop into cervical cancer. So how to identify patients at risk of progressive cervical lesions from those infected with HPV to avoid over treatment is a big issue in clinic. The aims of this study were to detect the expression of HPV L1 capsid protein and p16(INK4a) in cervical lesions and to investigate the combination expression of HPV L1 capsid protein and p16(INK4a) in cervical lesions and its diagnostic efficiency in clinic.

Analysis of the dose-response relationship between high-risk human papillomavirus viral load and cervical lesions.

The aims of this study were to explore the dose-response relationship between high-risk human papillomavirus (hrHPV) load and cervical lesions; the relationship between hrHPV viral load and the severity of cervical lesions; and the clinical application of the hybrid capture II (HC-II) system in the secondary prevention of cervical cancer. HrHPV viral load was detected by the HC-II system and cervical lesions were diagnosed from biopsied tissue. Curve estimation and Mantel trend analysis were used to explore the dose-response relationship between hrHPV viral load and cervical lesions.

[A case-control study on the risk factors for inguinal hernia in children].

Objective: Inguinal hernia is a common birth defect in children, but there is limited information about the risk factors for this disorder. The study aimed to explore the risk factors for the development of this disorder in children.

Methods: A frequency matching case-control study based on hospital group data was performed.

[Association between environmental risk factor exposure in the first trimester and nonsyndromic cleft lip with or without cleft palate: a case-control study].

Objective: To identify the environmental risk factors during the first trimester responsible for nonsyndromic cleft lip with or without cleft palate to collect data for prevention of this congenital defect.

Methods: A hospital-based case-control study was conducted to identify the risk factors by means of field investigation with standardized questionnaires. Single factor analysis and logistic regression of the data are performed using SPSS 13.
