Sources of stress and coping strategies among Chinese medical graduate students: a qualitative study.

Background: The incidence of mental health problems among medical graduate students is much higher than among students of other disciplines. This can have adverse consequences for the medical students themselves as well as their future patients. This study aims to understand the pressures faced by Chinese medical students and the current status of mental health education.

Effect of propofol and sevoflurane on postoperative fatigue after laparoscopic hysterectomy.

Background: Postoperative fatigue syndrome (POFS) is an important factor in postoperative recovery. However, the effect of anesthetic drugs on postoperative fatigue in female patients has been rarely studied. This study compared the effects of maintaining general anesthesia with propofol or sevoflurane on the incidence of POFS in patients undergoing laparoscopic hysterectomy.

Reducing carbon footprints and increasing net ecosystem economic benefits through dense planting with less nitrogen in double-cropping rice systems.

Excessive application of nitrogen fertilization in farmland systems can cause nitrogen wastage, environmental pollution, and increase greenhouse gas (GHG) emissions. Dense planting is one of the efficient strategies for nitrogen fertilizer reduction within rice production. However, there are paying weak attention to the integrative effect of dense planting with less nitrogen (DPLN) on carbon footprint (CF), net ecosystem economic benefit (NEEB) and its components in double-cropping rice systems.

[Effects of increased planting density with reduced nitrogen fertilizer application on greenhouse gas emission in double-season rice fields under water saving and simple cultivation mode].

To clarify the effects of increased density and reduced nitrogen on greenhouse gas emission in double-season paddy fields under the water-saving and simple cultivation mode, we used Luliangyou 996 (early rice) and Fengyuanyou 299 (late rice) as materials to collect greenhouse gas by closed static box method, monitored the dynamics of CH and NO emissions from different combinations of increased density and reduced nitrogen for early and late rice, and explored changes in cumulative CH and NO emissions, global warming potential (GWP) and greenhouse gas intensity (GHGI) as affected by different combinations of increased density and reduced nitrogen from double-season rice fields. The results showed that the cumulative emissions of CH and NO from different combinations were significantly different. Compared with the control (CK), cumulative CH emission, GWP and GHGI in the two seasons decreased by 50.

Effect of electrically stimulating acupoint, Zusanli (ST 36), on patient's recovery after laparoscopic colorectal cancer resection: a randomized controlled trial.

Objective: To investigate the effect of transcutaneous electrical acupoint stimulation (TEAS) on enhanced recovery after surgery (ERAS) in laparoscopic colorectal cancer resection and its clinical significance.

Methods: Sixty-four patients undergoing laparoscopic colorectal resection were randomly divided into two groups, the control group (group A) and the TEAS group (group B). Patients in the TEAS group received electroacupuncture stimulation of bilateral Zusanli (ST 36) at 30 min before anesthesia to the end of surgery.

[Application of Transcutaneous Electrical Acupoint Stimulation Combined with Transversus Abdominis Plane Block to Enhanced Recovery After Surgery in Patients Undergoing Laparoscopic Colorectal Cancer Resection: A Randomized Controlled Clinical Trial].

Objective: To explore the effect of transcutaneous electrical acupoint stimulation (TEAS) combined with transversus abdominis plane (TAP) block in the enhanced recovery after surgery (ERAS) in patients undergoing laparoscopic colorectal cancer resection (LCCR).

Methods: A total of 101 patients undergoing LCCR were randomly divided into three groups: control (＝34), TAP (＝35) and TEAS＋TAP (＝32). Conventional perioperative anesthesia management of the 3 groups was performed according to the ERAS guidelines.

[Effects of Water and Nitrogenous Fertilizer Coupling on CH4 and N2O Emission from Double-Season Rice Paddy Field].

To provide support for the efficient use of water and fertilizer technology to double-season rice cultivation, water and fertilizer coupling mode was applied in this research, including two irrigation methods and four N levels. The irrigation methods were flood irrigation and intermittent irrigation, while four N levels were high-N, middle-N, low-N and none-N. Field experiment was conducted to study the effect of water and fertilizer coupling mode on CH4 and N2O emission.
