Objective : To investigate the selective activation of 5-hydroxytryptamine neurons in the dorsal raphe nucleus(DRN5-HT) of rats with insomnia induced by p-chlorophenylalanine(PCPA) using chemical genetics techniques, and to explore whether it has a regulatory effect on comorbidities of insomnia and anxiety. Methods : 32 male SD rats were randomly divided into control group, PCPA model group(PCPA group), chemical activation group(hM3Dq+CNO group), and chemical control group(hM3Dq+Saline group). The anxiety level of experimental rats was evaluated through open field experiments and elevated cross maze experiments.In vivoelectroencephalography(EEG) was used to record propofol induced sleep and cortical EEG changes, and immunofluorescence staining was used to observe changes in c-Fos positive protein expression in 5-HT neurons. Results : The behavioral results showed that compared with the chemical control group, the anxiety level of the chemical activation group was significantly lower(P<0.05), and sleep duration was significantly prolonged(P<0.05). The expression level of c-Fos positive protein in DRN5-HT neurons in the chemical activation group was higher(P<0.05). The EEG results showed that the percentage of δ-band power between the chemical activation group and the chemical control group was higher(P<0.05), the power percentage in the α-band was relatively low(P<0.05). Conclusion Chemical activation of 5-HT neurons in the DRN region can improve anxiety levels and increase sleep duration in PCPA induced insomnia rats.

Objective: To observe the effects of apocynum venetum leaves extract(AVLE) on anxiety-like behavior caused by chronic restraint stress(CRS). Methods: Male C57BL/6 mice were randomly divided into 4 groups, 5 per group: control group(equivalent physiological saline 0.2 ml/10 g), CRS model group(equivalent physiological saline 0.2 ml/10 g), AVLE treatment group(AVLE 120 mg/kg) and positive control group(paroxetine hydrochloride 3 mg/kg). The anxiety mouse model of chronic restraint stress was established, and the anxiety level of mice treated with apocynum venetum leaf extract was evaluated by open field test and elevated cross maze test. Immunofluorescence staining was used to detect the changes of serotonin receptor in hypothalamic paraventricular nucleus. Chemogenetics combined with adeno-associated virus was used to detect the effect of hypothalamic oxytocin neurons on the anxiety regulation of AVLE. Results: Compared with the model group, apocynum venetum leaves extract could increase the total distance of open field exercise, the activity time, the time of mice entering the central area(P<0.05), and the activity distance and time of mouse elevated maze(P<0.05). The expression of serotonin 1A receptor in the paraventricular nucleus of hypothalamus was enhanced after treatment with AVLE, and inhibition of serotonin 1A receptor and oxytocin neurons in hypothalamic paraventricular nucleus could decrease activity level in mice(P<0.05). Conclusion AVLE can improve the anxiety state and activity ability of CRS mice, and its effect is related to serotonin receptor and oxytocin neurons in hypothalamic paraventricular nucleus.

Objective To cross-cultural adapt and test the reliability and validity of Humanistic Relationship Experience Scale (HRES) made by Boscart. Methods Cross-culture Adaptation was carried out by following American Academy of Orthopaedic Surgeons Evidence Based Medicine Committee (AAOS). A convenience sampling was conducted among 180 patients with chronic disease, and then assessed the reliability and validity of HRES. The internal consistency coefficient and the test-retest were used to assess the reliability of HRES, and the content validity index (CVI) and construct validity were used to assess the validity of HRES. Results In order to understand the purpose and content of the scale easily, the Chinese version title of HRES was revised to"Nursing Humanistic Care Experience Scale-Noninfectious Chronic Disease Patients Version (NHCES-NCDP)" after soliciting experts′ advice. The CVI of the scale was 1;factor analysis got three factors, which could explain 67.897％of the total variance. A 0.965 Cronbachαof total scale was obtained, and for each dimension range was 0.876-0.948;the test-retest reliability was 0.710 for the overall scale. Conclusion NHCES-NCDP is reliable and valid, which can be used to assess the experience of nursing humanistic care for patients with chronic diseases, and to explore nurses′implementation of nursing humanistic care.
