[Noise exposure-induced stress response and its measurement methods].

Noise, as an unavoidable stress (pressure) source in the modern life, affects animals in many ways, both behaviorally and physiologically. Behavioral changes may be driven by changes in hormone secretion in animals. When animals face with noise stress, the neuroendocrine systems, mainly the hypothalamic-pituitary-adrenal (HPA) axis, are activated, which promotes the secretion and release of stress hormones, and then leads to a series of behavioral changes.

[Effect of Partial Substitution of Chemical Fertilizers with Organic Fertilizers on NO and NO Emissions from a Peach Orchard].

Organic fertilizer substitution has been promoted as a weight loss, efficient, and diversified fertilizer substitution technology in agricultural production. However, there is a lack of comprehensive assessment of the impact of organic fertilizers on NO and NO emissions from orchards. In this study, NO and NO emissions from peach orchards were observed annually using static dark box-gas chromatography to compare the effects of chemical fertilizer application alone and partial replacement of chemical fertilizer treatment on NO emissions from peach orchards.

Association between serum antinuclear antibody and rheumatoid arthritis.

Background: The relationship between serum antinuclear antibody (ANA) and rheumatoid arthritis (RA) remains unknown. Therefore, we aimed to evaluate whether serum ANA was associated with an increased risk of RA in a case-control study.

Methods: Patients with rheumatoid arthritis hospitalized at Shandong Provincial Hospital from January 2018 to December 2022 were recruited as the case group, and patients with other types of arthritis and healthy people at the same time were taken as the control group.

Novel ultrastructural findings on cardiac mitochondria of huddling Brandt's voles in mild cold environment.

Reduced ambient temperature has a damaging effect on mammalian myocardium. Huddling as a cooperative behavior has evolved in social mammals as a strategy to maximize adaptation to environmental cooling. Here, we studied the effects of huddling behavior on mitochondrial morphology, number, and function in the myocardia of Brandt's voles (Lasiopodomys brandtii) under cool environmental temperatures (15 °C).

Transcriptome analysis revealed pivotal transporters involved in the reduction of cadmium accumulation in pak choi (Brassica chinensis L.) by exogenous hydrogen-rich water.

Hydrogen-rich water (HRW) has been widely used in research on plant resistance to Cd. However, the underlying molecular mechanism of HRW in ameliorating cadmium stress in vegetables is largely unknown. In this study, the RNA-sequencing analyses were used to characterize the role of HRW in the alleviation of Cd toxicity in Chinese cabbage seedlings.

[Clinical situation and analysis on the detection result of HIV antibody in Shandong province from 2003 to 2011].

Objective: To provide the basis for clinical acquired immunodeficiency syndrome (AIDS) surveillance and to avoid cross infection in hospital, we study the infection status of AIDS in Shandong province.

Methods: The fourth-generated Akzo's ELISA kit and the fourth generated Immunoluminometric detection reagent were used for HIV antibody screening for 399 303 cases of both inpatients and outpatients from Jan. 2003 to Dec.

Triptolide as an Alternative to IVIG Therapy for Kawasaki Disease in a Mouse Model.

Background: Kawasaki disease is treated by immunoglobulin therapy, which has adverse side effects like renal damage.

Aims: The aim of the present study was to explore the effectiveness of triptolide, a compound derived from threewingnut that has anti-inflammatory effects, on the treatment of Kawasaki disease in a mouse model.

Study Design: Animal experiment.

Combination therapy with lentinan improves outcomes in patients with esophageal carcinoma.

With a view to improving treatment response and the quality of life of cancer patients, this study investigated the clinical efficacy of combining lentinan, a flavonoid compound with antitumor abilities, with traditional chemotherapy in individuals with esophageal carcinoma (EC), with a particular focus on its effect on immune function. A total of 50 patients undergoing treatment for EC were evenly divided into two groups: control and experimental. Patients in the control group were treated with the chemotherapeutic agent tegafur (1,000 mg/day for 5 days); patients in the experimental group were treated with the same dosage of tegafur combined with 1 mg lentinan diluted in 250 ml normal saline.

[Effects of management regime on soil respiration from agroecosystems].

In order to examine the effects of management regime, such as nitrogen application and plowing method, on soil respiration from farmland, the static opaque chamber-gas chromatograph method was used to measure soil CO2 fluxes in situ. The field measurement was carried out for 5 growing seasons, which were the 2002-2003 wheat, 2003 maize and soybean, 2003-2004 wheat, 2004 maize and 2004-2005 wheat seasons. Our results showed that soil respiration increased in fertilizer-applied treatments compared with no fertilizer treatment after 3 times of fertilizer application on 9 November 2002, 14 February and 26 March 2003.

[Quantifying direct N2O emissions from paddy fields during rice growing season in China: model application].

Based on statistical analysis of field N2O measurements in rice paddies in China, the models on direct N2O emissions under different water regimes were established. After successes in model validation and input data verification, the models were used to quantify changes in direct N2O emissions from paddy fields during the rice growing season in mainland China between the 1950s and the 1990s. Due to increases in rice planting area and nitrogen input and changes in water regime, the models predicted that seasonal N2O-N emissions from rice paddies have increased from 9.

[Quantifying direct N2O emissions from paddy fields during rice growing season in China: model and input data validation].

The models on direct N2O emissions from rice paddies under different water regimes developed by the authors were validated against field measurements in China reported in 2005-2007 and in other regions. In flooding rice paddies (F), N2O emission predicted by the model was consistent with previous reports in other regions. Under the water regime of flooding-midseason drainage-reflooding (F-D-F), the model developed in this study was comparable to that established by using worldwide database.

[Quantifying direct N2O emissions from paddy fields during rice growing season in China: model establishment].

Various water management regimes, such as continuous flooding (F), flooding-midseason drainage-reflooding (F-D-F), and flooding-midseason drainage-reflooding-moist intermittent irrigation but without water logging (F-D-F-M), are currently practiced in paddy rice production in China. These water regimes have incurred a sensitive change in direct N2O emission from rice paddy fields. In order to establish statistical models quantifying the country-specific emission factor and background emission of N2O in paddy fields during the rice growing season, we compiled and statistically analyzed field data on 71 N2O measurements from 17 field studies that were published in peer-reviewed Chinese and English journals.

[Effect of organic material incorporation in rice season on N2O emissions from following winter wheat growing season].

In a field experiment, five fertilizer treatments including chemical fertilizer (CF), rapeseed cake + chemical fertilizer (RC + CF), wheat straw + chemical fertilizer (WS + CF), cow manure + chemical fertilizer (CM + CF), and pig manure + chemical fertilizer (PM + CF), were dedicated to examine the effect of organic materials incorporation in the rice season on N2O emissions from the following winter wheat season and to assess the climatic impacts from CH4 and N2O emissions in a rice-wheat rotation. Organic material was incorporated at the same rate (225 g x m(-2)) for organic treatments at the depth of 10 cm in the soil as the basal fertilizer just before rice transplanting. An identical synthetic nitrogen fertilizer was adopted for all treatments.
