ObjectiveTo explore the effect of emotional catharsis on the mental health status， coping style and satisfaction with the intervention among adolescents in Nanchong in the post-pandemic period.MethodsCompletely random sampling method was used to recruit 390 adolescents from 2 general secondary schools， 2 county secondary schools and 2 universities in Nanchong from January 2021 to April 2022. The subjects were divided into study group （n=195） and control group （n=195） by random number table method. The study group received emotional catharsis intervention. The control group received self-regulation and relaxation without any other intervention. Interventions for both groups lasted for 3 months. Before and after the intervention， the mental health status and coping style of the adolescents were assessed using the Symptom Checklist 90 （SCL-90） and the Simplified Coping Style Questionnaire （SCSQ）. Also， the participants rated the satisfaction with the intervention via self-made satisfaction questionnaire after the intervention.ResultsAfter intervention， the total SCL-90 score of study group was lower than that of control group （t=68.312， P

North China has specific regional advantages in the overall economic and social development of China, and water resources are the most prominent factor that affects the sustainable development of this region. This study focuses on the land spatial layout of water-and-land adapted planting in North China. Based on the analysis of agricultural planting structure and water and land resource layout in the current year (2018) of North China, and considering varied population, climate, and socio-economic scenarios and water resource constraints, the study proposes a scheme for optimizing the agricultural planting layout in North China that adapts to local water and land resource conditions. We suggest that the burden on production and supply of commercial grain and other commercial agricultural products in North China should be appropriately reduced. In terms of improving the regional water resource carrying capacity, Hebei Province should alleviate its water shortage through water transfer. Shanxi Province should improve the agricultural water use efficiency through agricultural mechanization and modernization. Shandong Province and Henan Province can moderately fallow the land and improve forest and grass coverage. It is also recommended to optimize the spatial layout of agricultural planting and adjust the planting structure to adapt to water. In shallow groundwater overexploitation areas as well as Tianjin City and the southeast of Hebei Plain where deep groundwater overexploitation is severe, semi-arid land planting systems and structures that adapt to precipitation should be developed, and the specific recuperation period should be determined according to the rate of groundwater recharge.

Remote sensing technology is widely used to obtain evapotranspiration (ETa), but whether it can distinguish the differences in farmland energy balance components and ETa under different irrigation methods has not been studied. We used Landsat 8 data as the primary dataset to drive the METRIC model and inverted the surface parameters and ETa of the Shiyang River Basin from 2014 to 2018. After improving the METRIC model using Ta obtained by the regression method instead of interpolation to calculate the net radiation flux (Rn), R2 was improved from 0.45 to 0.53, and the RMSE was reduced from 61 W/m2 to 51 W/m2. The ETa estimation results on satellite overpass days performed well, with R2 equal to 0.93 and RMSE equal to 0.48 mm when compared with the Eddy covariance method (EC) observations. Subsequently, the different growth stages and daily average ETa estimates of maize were compared with three observations (water balance, WB; Bowen ratio and energy balance method, BREB; and EC). The daily estimates of ETa correlate well with the observations of BREB (R2BI = 0.82, R2DI = 0.92; RMSEBI = 0.46 mm/day, RMSEDI = 0.32 mm/day) and EC (R2BI = 0.85, R2DI = 0.92; RMSEBI = 0.45 mm/day, RMSEDI = 0.34 mm/day), and the estimation for drip irrigation was found to be better than for border irrigation. The total accuracy of the ETa estimation on the five-year overpass day of maize farmland reached R2 = 0.93 and RMSE = 0.48 mm. With sufficient remote sensing data, the 4-year average ETa of maize was 31 mm lower for DI than for BI, and the mean value of ETa obtained from the three observation methods was 40 mm. The METRIC model can be used to distinguish ETa differences between the two irrigation methods in maize farmlands. [ABSTRACT FROM AUTHOR]

Atrial fibrillation (AF), the most common human cardiac arrhythmia, is associated with abnormal intracellular [Ca.sup.2+] handling. Diastolic [Ca.sup.2+] release from the sarcoplasmic reticulum via "leaky" ryanodine receptors (RyR2s) is hypothesized to contribute to arrhythmogenesis in AF, but the molecular mechanisms are incompletely understood. Here, we have shown that mice with a genetic gain-of-function defect in Ryr2 (which we termed [Ryr2.sup.R176Q/+] mice) did not exhibit spontaneous AF but that rapid atrial pacing unmasked an increased vulnerability to AF in these mice compared with wild-type mice. Rapid atrial pacing resulted in increased [Ca.sup.2+]/calmodulin-dependent protein kinase II (CaMKII) phosphorylation of RyR2, while both pharmacologic and genetic inhibition of CaMKII prevented AF inducibility in [Ryr2.sup.R176Q/+] mice. This result suggests that AF requires both an arrhythmogenic substrate (e.g., RyR2 mutation) and enhanced CaMKII activity. Increased CaMKII phosphorylation of RyR2 was observed in atrial biopsies from mice with atrial enlargement and spontaneous AF, goats with lone AF, and patients with chronic AF. Genetic inhibition of CaMKII phosphorylation of RyR2 in [Ryr2.sup.S2814A] knockin mice reduced AF inducibility in a vagotonic AF model. Together, these findings suggest that increased RyR2-dependent [Ca.sup.2+] leakage due to enhanced CaMKII activity is an important downstream effect of CaMKII in individuals susceptible to AF induction., Introduction Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is a significant contributor to cardiovascular morbidity and possibly mortality. Emerging evidence suggests an important role for abnormal [...]
