[Effects of Straw Mulching and Nitrogen Reduction on the Distribution of Soil Nitrogen and Groundwater Nitrogen Pollution].

To explore the effects of straw mulching and reduced nitrogen fertilization on the temporal and spatial patterns of soil nitrogen, groundwater nitrogen pollution, and summer maize yield, field experiments were carried out in the Hetao irrigation district in 2017 and 2018. The experiment involved the following seven treatments:a control (CK) treatment involving conventional fertilization and traditional tillage, and conventional nitrogen applications reduced by 30% (N1), 20% (N2), and 10% (N3) coupled with either straw surface covering (B) or deep straw burial (S). The results showed that the distribution of soil nitrogen in the CK treatment varied depending on soil depth, with an overall decreasing trend.

The effects of straw mulching combined with nitrogen applications on the root distributions and nitrogen utilization efficiency of summer maize.

To provide an appropriate tillage fertilization model for improving N utilization efficiency and increasing production, the field experiments were conducted to study the effects on root distributions and N utilization efficiency of summer maize involving different straw mulching modes combined with N fertilization. No (N0), low (N1), medium (N2), and high (N3) levels of N fertilization were incorporated into soil combined with the surface coverage straw (Treatment B) and the deeply buried straw (Treatment S). The traditional cultivation was used as control treatment.

[Physical exercise and mental health: cognition, anxiety, depression and self-concept].

This review focuses on the benefits of regular physical activity participation have mainly focused on cognitive functioning, anxiety and depression, and self-concept. It is well documented that ex- ercise can enhance cognitive functioning, improve executive function at old age, and improve mental abil- ity of children labeled as educational subnormal or disability. Regular exercise has been used to reduce stress and ward off anxiety and feelings of depression.

[Effect of xuebijing oral effervescent tablet on endotoxin induced fever and disseminated intravascular coagulation rabbit model].

In order to discover the mechanism of Xuebijing oral effervescent tablet (XBJOET) to treat infectious diseases, the effect of XBJOET on endotoxin induced rabbit fever and disseminated intravascular coagulation (DIC) was investigated. Auricle microcirculation in rabbit was detected by laser speckle blood perfusion imager system; coagulation function was measured by coagulation analyzer, fibrinolytic system was quantified by Elisa assay and micro thrombosis in tissues was observed with HE staining under light microscope. The results demonstrated that the body temperature of rabbit decreased significantly at 1-3 h after administration with 4.

[Effects of jin chai antiviral capsule on IFITM3 expression in mice].

This study is to investigate the treatment of Jin Chai antiviral capsule for influenza virus FM1/47 (H1N1) infection. The model of pneumonia was established by dropping influenza virus into the nose of normal mice, real-time PCR and Western blot technique were used to detect the virus load and the interferoninducible transmembrane protein3 (IFITM3) in lung of mice at the 1st day, 3rd day, 5th day and 7th day after affected. The results showed that Jin Chai antiviral capsule in large, middle, small dose groups can decrease virus load significantly at each time point, after being affected (P<0.

[Effects of yin qiaojiedu soft capsule on influenza virus load and M1 expression in mice].

This study is to investigate the treatment of YinQiaojiedu soft capsule for influenza virus A/PR8/34 (H1N1) infection. The model of pneumonia was established by dropping influenza virus into the nose of normal mice, and the lung index and death rate were observed. Real time RT-PCR and Western blotting technique were used to detect the virus load and the relative expression of M1 protein in lungs of mice on the 1st, 3rd, 5th and 7th day after infection.

[Pharmacodynamic experiment of the antivirus effect of Houttuynia cordata injection on influenza virus in mice].

It is to investigate the effect of two kinds of Houttuynia Cordata Injection on preventing and treating H1N1 influenza virus infection in mice. Pneumonia model was set up by intranasal infection of the normal and immunocompromised mice with influenza virus FM1 and PR8. The two injections were administered before and after the administration of virus, separately, and the lung index was observed.

[The effects of zhubi capsule on adjuvant arthritis in rats].

Objective: To explore the therapeutic effects and mechanisms of Zhubi capsule on adjuvant arthritis (AA) in rats.

Method: The model of rat was induced by intradermal injection of CFA. The perimeter of ankle joint was measured at different time points.

[Experimental study on hemostatic effect of flos sophorae and its extracts].

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.
