Gastric hyperplastic polyps inversely associated with current infection.

The incidence of gastric hyperplastic polyps (HPs) has been on the rise in recent years. The contribution of infection to this trend has remained to be elucidated. The present study aimed to explore the association between HPs and in China, an area with a high infection rate of .

Prevalence of depression and anxiety in patients with chronic digestive system diseases: A multicenter epidemiological study.

Aim: To investigate the prevalence of depression and anxiety in patients with chronic digestive system diseases.

Methods: A total of 1736 patients with chronic digestive system diseases were included in this cross-sectional study, including 871 outpatients and 865 in-patients. A self-designed General Information for Patients of the Department of Gastroenterology of General Hospitals questionnaire was used to collect each patient's general information, which included demographic data (including age, sex, marital status, and education) and disease characteristics (including major diseases, disease duration, principal symptoms, chronic pain, sleep disorder, and limited daily activities).

[Analysis of Three Polycyclic Aromatic Hydrocarbons in Solution Based on Two-Dimensional Fluorescence Correlation Spectroscopy].

Polycyclic aromatic hydrocarbons (PAHs) are listed as the priority pollutants. It is difficult to resolve effectively the peaks of PAHs by conventional one-dimensional fluorescence spectroscopy due to its low content and the overlapping fluorescence three mixed ystems and a total of 27 samples, are to be prepared with different concentrations of three PAHs. Concentrations of three PAHS are monotonically increasing or decreasing in each mixed system.

[Responses of Pinus tabulaeformis forest ecosystem in North China to climate change and elevated CO2: a simulation based on BIOME-BGC model and tree-ring data].

Based on BIOME-BGC model and tree-ring data, a modeling study was conducted to estimate the dynamic changes of the net primary productivity (NPP) of Pinus tabulaeformis forest ecosystem in North China in 1952-2008, and explore the responses of the radial growth and NPP to regional climate warming as well as the dynamics of the NPP in the future climate change scenarios. The simulation results indicated the annual NPP of the P. tabulaeformis ecosystem in 1952-2008 fluctuated from 244.

Expression of interleukin-17 and its clinical significance in gastric cancer patients.

To investigate the expression of interleukin 17 (IL-17) in serum and tumor tissues, and evaluate the correlation between IL-17 and clinical characteristics from patients with gastric cancer. From January 2009 to January 2010, total 50 patients with gastric cancer and 50 healthy controls were enrolled. The patients included 32 males and 18 females with average age of (62.

Expression and clinical significance of syndecan-1 mRNA and HPA-1 mRNA in colorectal cancer detected with real-time fluorescent quantitative polymerase chain reaction.

Background And Objective: Invasion and metastasis are the most common causes of mortality for patients with colorectal neoplasms, and blocking invasion and metastasis in a timely fashion has become a hot research focus. We investigated the expression of the messenger RNA of Syndecan-1 and HPA-1 in colorectal cancer, and their correlation with invasion and metastasis.

Methods: Real-time fluorescent quantitative polymerase chain reaction (PCR) was used to detect the expression of Syndecan-1 and HPA-1 in specimens from 49 patients with colorectal cancer, 49 paired adjacent colorectal neoplasms (2 cm from the carcinoma), and 49 surgical margins of paired normal colorectal mucosa tissue (5 cm from the carcinoma), to analyze their correlation with clinicopathologic characteristics of colorectal neoplasm.

[Dendrochronology of Chinese pine in Mulan-Weichang, Hebei Province: a primary study].

Dendroclimatic methods were used to investigate the relationships between the growth of Chinese pine (Pinus tabulaeformis Carr.) and the climatic parameters in Mulan-Weichang of Hebei Province. The results showed that Chinese pine presented high sensitivity to climatic changes, and its earlywood width showed the highest sensitivity.
