Objective: To Study the effect of group sports training consultation on psychological health status of college students. Methods: Sixty-two college students were trained to do excises by means of low rhythm of the heart with cognitive therapy. Results: After the training and cognitive therapy, the score of Beck Depression Inventory significantly lowered. Conclusion: The sports training combined with cognitive therapy was effective in improving college student's depression.

Objective:To explore the influence of ADHD on academic achievement of undergraduates Method:104 undergraduates were randomly selected and divided into two groups by characteristics of adults with ADHD according to DSM-IV criteria Their academic achievements were also recorded SAS was used to assess their anxiety level Result:After controlled influence of anxiety and gender, academic achievement of undergraduates in ADHD group was significantly lower than that in non-ADHD group Conclusion:ADHD has negative influence on academic achievement of undergraduates

Objective: To explore the application and effect of the PDCA cycle nursing management model in the treatment of peri-implant mucositis. Methods : Thirty patients with peri-implant mucositis were treated nonsurgically. Before treatment, the 30 patients had no history of systemic diseases, drug allergies, or bad habits. According to the principle of single-blind randomized control, the patients were divided into two groups: 15 patients were assigned to the control group and received routine clinical nursing and oral hygiene education according to the doctor′s prescription; and 15 patients were assigned to the intervention group, in which the PDCA cycle nursing management model was adopted. The four steps of “plan, do, check and act” were carried out. The plaque index (PL), gingival index (GI) and probe depth (PD) in the two groups were recorded before treatment and 3 and 6 months after treatment. Results: There was no significant difference in the PL, GI or PD between the intervention group and the control group before treatment (P > 0.05). Three months after treatment, the PL in the intervention group was 1.25 ± 0.44, while the PL in the control group was 1.49 ± 0.39, with a significant difference (t=2.56, P=0.008); the GI in the intervention group was 1.21 ± 0.43, while the GI in the control group was 1.56 ± 0.37, with significant difference (t=2.94, P=0.006); and the PD in the intervention group was 4.39 ± 0.41 while the PD in the control group was 4.47 ± 0.52 mm, with no significant difference (t=2.24, P=0.062). Six months after treatment, the PL in the intervention group was 1.26 ± 0.48, while the PL in the control group was 1.51 ± 0.42, with a significant difference (t=2.66, P=0.007); the GI in the intervention group was 1.34 ± 0.28, while the GI in the control group was 1.74 ± 0.48 (t=2.98, P=0.008); and the PD in the intervention group was 4.46 ± 0.52 mm, while the PD in the control group was 4.54 ± 0.66, with no significant difference (t=2.28, P=0.077). Conclusion The PDCA cycle nursing management model can enhance patients′ awareness of oral health maintenance, reduce gingival plaque accumulation, and effectively improve the health status of peri-implant tissues.
