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.

We collected 599 policies related to medical treatment combination issued by local governments from October 2010 to December 2022 to study the differences and characteristics of medical treatment combination policies in different regions of China. Descriptive statistics and the structural topic model were used to compare medical treatment combination policies in four major economic regions (West, Central, East, Northeast) of China from three dimensions: the number of policies issued, policy types and policy topics. The study shows that: the structure of Chinese local medical treatment combination policy system was not balanced and was characterized by an emphasis on implementation rules rather than standard specifications; the construction of hierarchical diagnosis and treatment service system and the management model of medical treatment combination are hot topics, while the topics such as supporting measures and disease prevention and treatment have not received widespread attention. The construction of medical treatment combination in each region shows diversified exploration. The local government needs to issue relevant policies according to the regional differences, so as to supplement the shortcomings of the policy and promote the improvement of the policy system of the regional medical treatment combination.

Objective: To compare the hemostatic effect of Flos Sophorae in crude, parched and carbonized forms and its extracts, including rutin, quercetin and tannin., Methods: All the testing samples were orally administered to the experimental animals for 5 days, then the bleeding time (BT), coagulation time (CT), platelet count and capillary permeability (CP) in the treated mice were tested, and the prothrombin time (PT), fibrinogen (FBG) content and platelet aggregation rate (PAR) in the treated rats were determined., Results: All the samples could lower the CP, BT and CT in mice and also decrease the plasma PT in rats. All three forms of Flos Sophorae could increase FBG in rats, while the three extracts of it could inhibit the PAR in rats obviously. In addition, rutin had the effect of raising the platelet count., Conclusion: All the three forms and three extracts of Flos Sophorae have hemostatic effect, the effect of parched and carbonized form is higher than that of crude drug. The mechanism of the hemostatic effect of the six kinds of sample might be various.
