Objective:To explore the mediating effect of empathy between personality traits and death attitude in nursing students.Methods:From April to May 2022, a total of 237 undergraduate nursing students were surveyed by general information questionnaire, big five inventory, Jefferson scale of empathy for nursing students, and death attitude profile-revised. Common method bias test, correlation analysis and descriptive analysis were conducted by SPSS 26.0 software.PROCESS macro program was used to test the mediating effect.Results:Agreeableness(32.78±4.92), empathy(110.03±16.83)were positively correlated with positive death attitude(57.95±12.35)( r=0.274, 0.571, both P<0.01), neuroticism(23.00±4.78)was positively correlated with negative death attitude(31.81±10.04)( r=0.199, P<0.01), empathy was negatively correlated with negative death attitude ( r=-0.226, P<0.01). Empathy partially mediated the relationship between neuroticism and negative death attitude, the mediating effect accounted for 16.08%(0.032/0.199) of the total effect, and empathy played a completely mediating role between the agreeableness and positive death attitude. Conclusion:The death attitude of undergraduate nursing students is mainly natural acceptance. Personality traits can directly affect death attitude and also indirectly affect death attitude through empathy.

ObjectiveTo investigate the effects of Asari Radix et Rhizoma-Zingiberis Rhizoma herb pair （XGHP） on lung and liver lipid metabolism in rats with chronic obstructive pulmonary disease （COPD）. MethodForty SD male rats were divided into a normal group （10 rats） and a model group （30 rats）. The method of cigarette smoke + tracheal injection of lipopolysaccharide（LPS） + cold stimulation was used to replicate COPD model with the syndrome of cold phlegm obstruction in lung. A COPD group， a XGHP group （5.4 g·kg^-1·d^-1）， and an aminophylline group （0.5 g·kg^-1·d^-1） were established after successfully inducing the model， with 10 rats in each group. After treatment， the serum triglyceride （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） levels of rats in each group were measured. Gas chromatography-mass spectrometer （GC-MS） was used to detect the differential metabolites in the lung and liver tissues of rats in each group， and the relevant targets of the differential metabolites were predicted by network pharmacology. Molecular docking was used to verify the binding ability of key components in XGHP to the relevant targets in network pharmacology. The mRNA and protein expression levels of peroxisome proliferator-activated receptor α （PPARα） and fatty acid binding protein 4 （FABP4） in lung and liver tissues of rats in each group were detected by real-time polymerase chain reaction （PCR） and Western blot. ResultXGHP significantly increased the levels of TG， TC， and LDL-C in serum （P<0.05）， and decreased the level of HDL-C （P<0.05） in rats with COPD. GC-MS results showed that there were 8 lung differential metabolites and 17 liver differential metabolites in the COPD group and XGHP group. Network pharmacology predicted 59 common targets for the two differential metabolites， mainly enriched in the PPAR signaling pathway. Molecular docking results showed that the main components in XGHP were well combined with both PPARα and FABP4. Real-time PCR showed that XGHP effectively up-regulated the expression levels of PPARα and FABP4 mRNA （P<0.05）， and Western blot showed that XGHP effectively up-regulated the expression levels of PPARα and FABP4 proteins （P<0.05） in lung and liver tissues of rats with COPD. ConclusionXGHP effectively improves the blood lipid levels of rats with COPD， which may be related to the increase of the expression levels of PPARα and FABP4 mRNA and proteins in the PPAR signaling pathway， thus regulating lung and liver lipid metabolism.

Objective:To develop a family-involved institutional care behavior scale for the elderly and provide a tool for assessing the status quo and level of long-term institutional care for the elderly involving the family.Methods:From December 2018 to July 2019, based on the theory of balance and responsibility sharing and the conceptual model of family participation, the dimensions and item pools of the family-involved institutional care behavior scale for the elderly were constructed through literature review, semi-structured interviews and expert group meetings. Totally 18 experts from 11 provinces and cities in China related to this field were selected, and the Delphi method was used to conduct two rounds of consultations by correspondence.

Results:In the first and second rounds of consultations by correspondence, the positive coefficients of the experts were 90% and 100%; the authority coefficient was 0.925; and the Kendall's W were 0.160 and 0.287, respectively (both P<0.01) ; the coefficients of variation were 0.10-0.31 and 0.05-0.24; the importance score of items were 3.67-4.78 and 3.78-4.97. Finally, the family-involved institutional care behavior scale for the elderly including 6 dimensions and 35 items were constructed. Conclusions:The construction of the family-involved institutional care behavior scale for the elderly is reliable and robust, which can provide a reference for further developing the content of family participation in care institutions for the elderly and improving the quality of life in the elderly.

OBJECTIVEOn the basic therapy, to assess the clinical effects of dynamic scalp acupuncture, scalp acupuncture combined with proprioceptive neuromuscular facilitation (PNF) therapy and simple PNF therapy for upper limb motor impairment in ischemic post-stroke spastic hemiplegia.

METHODSA total of 90 cases were randomly assigned into a PNF group, a dynamic scalp acupuncture group and a scalp acupuncture group, 30 cases in each group. Basic therapy and PNF therapy were applied in the three groups. PNF therapy was used during scalp acupuncture in the dynamic scalp acupuncture group. PNF therapy was applied after scalp acupuncture in the scalp acupuncture group. The points were the upper 1/5 and middle 2/5 of (MS 6) and (MS 7) at the lesion side, the hemiparalysis contralateral side. The treatment was given for 6 months, once a day and 1 month as a course. The modified Ashworth scale (MAS), the Fugl-Meyer motor assessment (FMA) and Barthel index (BI) were observed before treatment and 2 weeks, 1 month, 3 months, and 6 months after treatment.

RESULTSThe MAS 1 month, 3 months and 6 months after treatment were improved compared with those before treatment in the three groups ( all <0.05), and the MAS results in the dynamic scalp acupuncture group were better than those in the PNF and scalp acupuncture group (all <0.05). The FMA and BI scores 1 month, 3 months and 6 months after treatment were higher than those before treatment (all <0.05). The FMA Scores in the 3 time points and after treatment in the dynamic scalp acupuncture group were higher than those in the other two groups (all <0.05).

CONCLUSIONPNF therapy during scalp acupuncture can relieve the spasmodic condition of patients with upper limb motor impairment in ischemic post-stroke spasmodic hemiplegia, and improve the limb function and life activity, which is better than PNF therapy after scalp acupuncture and simple PNF therapy.
