With the continuous development of modern badminton, higher requirements were put forward for the comprehensive quality of athletes. Studies show that players' ability of changing direction play an important role in badminton competition. In the present study, the SpeedCourt test system was used to study factors of badminton players' variable direction ability.
A total of 101 badminton players were included. The SpeedCourt test system was used to test the variable direction ability of players through three categories speed chase, jump and reaction. Principal component analysis and moment structure analysis were used to analyze the test data.
Four influencing factors were found of badminton players' variable direction ability; these are moving speed, coordination, reaction, and explosive force. The structural equation model of variable direction ability and the 4 influencing factors fit well with the measured data. The correlation between variable direction ability and coordination was the highest (r=0.91), followed by moving speed (0.86), reaction (r=0.81), and lower extremity explosive force (r=0.79).
This paper demonstrates the structural equation model of badminton players' ability to change direction from an empirical point of view, which lays a foundation for the study of badminton players' agility and provides a reference for sports practice.

To explore the effect mechanism of "treat the spleen" therapy on immune thrombocytopenia (ITP) based on the characteristics of vasoactive factors.
The ITP mice model was established by passive immunomodeling. 120 successfully modeled BALB/c mice were randomly divided into 6 groups normal group, model group, prednisone group, Guipi Decoction group, Jianpi Yiqi group, and Jianpi Shexue group. These mice were treated with medicine for 16 days. After treatment, the platelet (PLT) counts and the degree of bleeding were evaluated, and the serum ET-1, NO, NOS3, TXA2, PGI2, vWF, VCAM-1, and TM contents of the model mice were detected by enzyme-linked immunosorbent assay (ELISA).
The PLT counts in peripheral blood of mice in each experimental group significantly decreased compared with that in the normal group (P<0.01). On the 8th day after commencing administration, compared with the model group, PLT counts of mice in each experimental group significantly increased (P<0.01). Before administration, all groA2 and VCAM-1, while down-regulating the levels of PGI2 and TM. Therefore, balancing the procoagulant and anticoagulant factors might be one of the effective mechanisms of hemostasis.
In addition to increasing the PLT counts in peripheral blood of ITP model mice to achieve a hemostatic effect, the "treat the spleen" recipes up-regulated the levels of TXA2 and VCAM-1, while down-regulating the levels of PGI2 and TM. Therefore, balancing the procoagulant and anticoagulant factors might be one of the effective mechanisms of hemostasis.
During the coronavirus disease 2019 (COVID-19) epidemic, tumor patients and their families might suffer from greater psychological stress as a result of anxiety or other psychological disorders. We conducted an online study during the epidemic to explore the mental state of tumor patients and their families during this extraordinary time.
A cross-sectional survey was carried out. Questionnaires were distributed through the WeChat "Questionnaire Star" network. The snowball sampling technique was adopted and further promoted by subjects who had completed the questionnaire.
A total of 1,030 valid questionnaires were collected. There were 609 (59.13%) tumor patients and 421 (40.87%) family members. click here One hundred and fifty-six (15.15%) subjects had anxiety, among which 65 (6.31%) had moderate to severe anxiety. Single-factor analysis indicated that age (>60 years old), the farmer occupation, and a high sleep disorder assessment score were risk factors for anxiety, while the latter two might also be independent risk factors, as suggested by multi-factor analysis. Infrequent contact with doctors was an independent risk factor for cancer patients, while uninterrupted anti-tumor therapy was an independent protective factor. 40.19% of the subjects expressed a need for psychosocial support during the COVID-19 period.
The COVID-19 outbreak resulted in tumor patients and their relatives experiencing greater psychological pressure than usual, and patients were more worried about anti-tumor treatment and disease progression impacted by the epidemic. Both groups had a significant need for psychosocial help.

The purpose of this study was to explore the value of comprehensive nursing intervention in the perioperative period of ruptured bleeding of ectopic pregnancy.
From January 2015 to January 2020, 164 patients with rupture and bleeding of ectopic pregnancy who needed laparoscopic treatment in the department of gynecology at our hospital were selected and randomly divided into the basic nursing group and the comprehensive nursing group, with 82 cases each. During the perioperative period, comprehensive nursing intervention or basic nursing intervention were performed, and the nursing effects of the two nursing interventions were compared.
The disappearance time of abdominal pain, the time to get out of bed, and the length of hospitalization in the comprehensive nursing group were significantly shorter than those in the basic nursing group (P<0.05). After surgery, blood sugar levels, aldosterone, cortisol, C-reactive protein (CRP), and IL-6 in the two groups were significantly higher than those before suent effect and significantly shorten the recovery time of patients, which is worthy of clinical promotion.
In summary, a comprehensive nursing program during the perioperative period can improve the treatment effect and significantly shorten the recovery time of patients, which is worthy of clinical promotion.
