Effects of Cadmium Exposure on Leydig Cells and Blood Vessels in Mouse Testis.

Environmental exposure to cadmium (Cd) contributes to a decline in the quality of human semen. Although the testis is sensitive to Cd exposure, the mechanism underlying how cadmium affects the testis remains to be defined. In this study, male mice were treated with intraperitoneal injections of 0, 0.

Autoantibodies against p53, MMP-7, and Hsp70 as Potential Biomarkers for Detection of Nonmelanoma Skin Cancers.

Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are two predominant histological types of nonmelanoma skin cancer (NMSC), lacking effective early diagnostic markers. In this study, we assessed the diagnostic value of autoantibodies against p53, MMP-7, and Hsp70 in skin SCC and BCC. ELISA was performed to detect levels of autoantibodies in sera from 101 NMSC patients and 102 normal controls, who were recruited from the Cancer Hospital of Shantou University Medical College.

A Study on the Psychological Factors Affecting the Quality of Life Among Ovarian Cancer Patients in China.

Purpose: We aim to test whether resilience mediates the association of fear of progression (FoP) with quality of life (QoL) among ovarian cancer patients in China.

Methods: We collected 230 questionnaires from the First Affiliated Hospital of China Medical University in Liaoning Province, and 209 completed the questionnaire survey. The survey instrument consisted of four questionnaires: a sociodemographic and clinical characteristics questionnaire, the Functional Assessment of Cancer Therapy general instrument, the Fear of Progression Questionnaire-Short Form and the Connor-Davidson Resilience Scale.

Perceived Organizational Support Associated with Depressive Symptoms Among Petroleum Workers in China: A Cross-Sectional Study.

Objective: The objective of this study was to explore the association between perceived organizational support (POS) and depressive symptoms, and to further explore whether self-efficacy can act as a moderator between POS and depressive symptoms among Chinese petroleum workers.

Methods: There was a cross-sectional study conducted at a petrochemical enterprise in Liaoning Province, China, from July to August 2018. A series of questionnaires were accomplished by 1836 petroleum workers, including the Center for Epidemiologic Studies Depression Scale (CES-D), the Survey of Perceived Organizational Support (SPOS), and the General Self-Efficacy Scale (GSES).

Serum IGFBP-1 as a potential biomarker for diagnosis of early-stage upper gastrointestinal tumour.

Background: Early detection would improve upper gastrointestinal cancer prognosis. We aimed to identify serum protein biomarker for the detection of early-stage upper gastrointestinal cancer.

Methods: We performed a three-tiered study including 2028 participants from three medical centres.

Effects of CD4 cell count and antiretroviral therapy on mucocutaneous manifestations among HIV/AIDS patients in Yunnan, China.

Background: The affecting factors of mucocutaneous manifestations in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients remain unclear in China.

Methods: A retrospective analysis was conducted among HIV/AIDS patients in Yunnan, China. The demographic data, mucocutaneous manifestations, CD4 cell counts, and antiretroviral therapy (ART) regimens were collected.

Serum Insulin-Like Growth Factor Binding Protein 7 as a Potential Biomarker in the Diagnosis and Prognosis of Esophagogastric Junction Adenocarcinoma.

Background/aims: Esophagogastric junction adenocarcinoma (EJA) is a malignant tumor associated with high morbidity and has attracted increasing attention due to a rising incidence and low survival rate. Pathological biopsy is the gold standard for diagnosis, but noninvasive and effective tests are lacking, resulting in diagnoses at advanced stages. This study explored the diagnostic value of insulin-like growth factor binding protein 7 (IGFBP7) in EJA.

Combined detection of serum autoantibodies as diagnostic biomarkers in esophagogastric junction adenocarcinoma.

Background: We previously found that autoantibodies against a panel of six tumor-associated antigens (p53, NY-ESO-1, MMP-7, Hsp70, PRDX6 and Bmi-1) may aid in early detection of esophageal squamous cell carcinoma. Here we aimed to evaluate the diagnostic value of this autoantibody panel in esophagogastric junction adenocarcinoma (EJA) patients.

Methods: Serum autoantibody levels were measured by enzyme-linked immunosorbent assay in a training cohort and a validation cohort.

[Quality of realgar and its influencing factors based on toxicity].

The results of a toxicity analysis showed differences from those of the existing experimental data. Therefore, HPLC-ICP-MS was used to analyze the soluble arsenic content at different valences in realgar prepared with water grind processing, which were collected from 3 companies. The results showed that the free arsenic of the 3 companies did not exceed the limit of Chinese Pharmacopoeia.
