Climate change has evolved from an environmental issue into a global public health crisis, posing severe challenges to healthcare systems. Issues such as shifts in patient disease patterns, increased care demands for vulnerable populations, and insufficient resilience in nursing systems are becoming increasingly prominent. As the frontline of healthcare delivery, nursing practice directly confronts multiple health risks triggered by climate change. Under the Healthy China 2030 strategy, the role of nursing in addressing climate change cannot be overlooked. Therefore, this paper systematically reviewed the impacts of climate change on nursing practice and corresponding domestic and international strategies, and proposed recommendations for localized development pathways. First, strengthen climate health literacy in nursing education by integrating the climate change system into curricula and clinical practice. Second, promote nursing policy participation in global health governance to establish a climate-adaptive nursing policy system with Chinese characteristics. Finally, establish a multidisciplinary nursing research framework to foster integration among nursing science, climate science, public health, traditional Chinese medicine, and other relevant fields. This paper aims to provide theoretical foundations for constructing a climate-adaptive nursing system with Chinese characteristics, thereby advancing the coordinated development of Healthy China initiative and climate governance.

OBJECTIVE To prepare the β -cyclodextrin ( β -CD) inclusion complex with volatile oil from Qianghuo qushi qingwen granules, and to characterize and quantitatively analyze the inclusion complex. METHODS The comprehensive scores calculated by inclusion rate and inclusion compound yield were used as indicators for screening the inclusion method. The single-factor experiments and Box-Behnken response surface experiments were used to op timize the inclusion conditions, with the above comprehensive score as response value, and taking the ratio of β -CD to volatile oil, inclusion temperature and inclusion time as indexes. The volatile oil inclusion complex of Qianghuo qushi qingwen granules was prepared according to the determined optimal process, followed by validation. Ultraviolet (UV)-visible spectroscopy, thin-layer chromatography (TLC), and microscopic imaging were also performed. Ultra-high performance liquid chromatography was used to determine the contents of perillaldehyde, pogostone and atractylodin. RESULTS The saturation aqueous solution method was adopted. The optimal inclusion process conditions were as follows: the ratio of β -CD to volatile oil was 7.5∶1, the inclusion temperature was 40 ℃, and the inclusion time was 2.2 h. In three verification experiments, the average inclusion rate was 72.32%, the average yield of inclusion compound was 74.45%, the average comprehensive score was 72.96 points, and the relative error with the predicted value (74.15 points) of the model was 1.61%. UV-visible spectroscopy, TLC and microscopic imaging showed that β -CD and volatile oil successfully formed a new inclusion complex. The average contents of perillaldehyde, pogostone and atractylodin were 4.498 2, 0.814 9, 0.905 7 mg/g, respectively, with RSDs of 0.31%, 0.56% and 0.63% ( n =3). CONCLUSIONS A stable and feasible preparation process of the volatile oil inclusion complex of Qianghuo qushi qingwen granules is successfully established.

Objective To establish an "human serum - porcine aortic endothelial cells (PAEC) - human platelets" in vitro model and explore the mechanism of xenotransplantation-related coagulation dysfunction mediated by immune complexes - platelet FcγRⅡa (CD32a) receptor. Methods Healthy human serum was co-incubated with PAEC to prepare the supernatant containing immune complexes, which was then used to stimulate healthy human platelets, or directly treated with the serum of xenogeneic liver transplant recipients. Flow cytometry was used to detect platelet activation markers CD62P and surface IgG binding levels, and the platelet adhesion function was evaluated by platelet-PAEC adhesion experiments. CD32a blocking antibody IV.3 and SYK blocker SKYIN 4 were used to clarify the signaling pathways. Results The supernatant from the co-incubation of healthy human serum and PAEC could significantly induce platelet activation and endothelial adhesion. The use of the serum from xenogeneic liver transplant recipients could also significantly induce platelet activation. Antibody IV.3 and SYK blocker SKYIN 4 could significantly inhibit these effects. Conclusions In xenotransplantation, the immune complexes formed by human serum antibodies and porcine endothelial antigens may induce abnormal platelet activation through the platelet CD32a receptor, which is an important mechanism of non-complement-dependent post-transplant coagulation dysfunction, providing a new target for the intervention of coagulation complications in xenotransplantation.

BACKGROUND:At present,there is a main kind of operation,which is represented by the proximal femoral nail antirotation,to treat femoral intertrochanteric fractures,but some sequelae still occur such as internal fixation loosening,failure,and nail withdrawal.We designed a new femoral neck spiral blade system to solve this problem,so we analyze the mechanical structure by the finite element method that can be regard as the theoretical basis for the system.OBJECTIVE:To compare the mechanical properties of the new femoral neck spiral blade system and the proximal femoral nail antirotation in the treatment of femoral intertrochanteric fracture by the finite element method.METHODS:Based on the finite element model of the femur,the A1.2 and A2.2 femoral intertrochanteric fracture models were established according to the AO fracture classification principle of 2018 edition.The models were fixed with the proximal femoral nail antirotation and the new internal fixation system,applying an axial load of 700,1 400,and 2 100 N above the femoral head.The mechanical characteristics of the two internal fixation methods were respectively compared and analyzed by observing the maximum equivalent stress and the maximum deformation of each group.RESULTS AND CONCLUSION:(1)The maximum equivalent stress of the new internal fixation group under different compressive loads was smaller than that of the proximal femoral nail antirotation group.(2)In the A1.2 fracture model,under different compression loads,the deformation of the new internal fixation system was smaller than that of the proximal femoral nail antirotation group,and the average value of difference between the two was 1.113 mm;the result of the A2.2 type fracture model was the same as that in the A1.1 with an average value of difference of 2.017 mm between the two.(3)In the A1.2 fracture model,under different compressive loads,the maximum deformation of the spiral blade fixed by the new internal fixation system was smaller than that of the proximal femoral nail antirotation group,and the average value of difference between the two was 1.062 mm;the result of the A2.2 type fracture model was the same as that in the A1.1 with an average value of difference of 1.891 mm between the two.(4)The results indicate that the new femoral neck spiral blade system has a lower internal fixation stress value compared to the proximal femoral nail antirotation,and a smaller displacement value of the femur after fixation and internal fixation.It can more effectively fix fractures and prevent the spiral blade from retracting or cutting out in the femoral neck.
