Objective To observe the effects ofLiuwei Dihuang Decoction on cAMP and PDE3B in adipose tissues of rats with type 2 diabetes;To explore its mechanism.MethodsTotally 80 SD rats were randomly divided into two groups:control group and molding group. Rats in the molding group established the type 2 diabetic models by feeding high sugar and fat diet combined with intraperitoneal injection of Streptozotocin. The successful modeling rats were divided into model group, Rosiglitazone group, andLiuwei Dihuang Decoction group. Administration groups were given relevant medicine for gavage, while model group and blank group were given the same amount of normal saline for 30 days. FBG levels were detected, and cAMP and INS levels were detected by ELISA. The protein expressions of PDE3B in adipose tissues were determined by Western blot. The mRNA expressions of PDE3B in adipose tissues were detected by RT-PCR.Results Compared with the model group, the FBG and INS levels in type 2 diabetic rats were reduced in Rosiglitazone group andLiuwei DihuangDecoction group (P<0.05,P<0.01). InLiuwei Dihuang Decoction group, the protein and mRNA expressions of PDE3B in the adipose tissues were higher, and cAMP levels were lower than the model group (P<0.01).ConclusionLiuwei Dihuang Decoction can increase PDE3B expression, and decrease cAMP level, which may be one of the mechanisms for improving insulin resistance in type 2 diabetic rats.

Serbia is a parliamentary republic country in Southeast Europe. It implements a health security system with social insurance as the mainstay and social assistance as a supplement. Ischemic heart disease, stroke and Alzheimer’s disease are the major causes of death, and the mortality rates of cardiomyopathy and chronic kidney disease are increasing. Serbia has relevant legislation on traditional medicine. Acupuncture, as the main form of Traditional Chinese Medicine (TCM), has been introduced to Serbia in an early stage. Acupuncture was recognized as a legal medical method in 2005, and then the corresponding educational institutions of TCM were established soon. However, the limitation of acupuncture treatment application, difficulty in access to Chinese medicine, and undeveloped of TCM education system, all of them restrict the development of TCM in Serbia. It is recommended to improve the development and dissemination of Chinese medicine in Serbia, like to increase the promotion of acupuncture, pay attention to the Chinese medicine for preventive health care, and strengthen TCM education.

The induced pluripotent stem cells (iPSCs), derived by ectopic expression of reprogramming factors in somatic cells, can potentially provide unlimited autologous cells for regenerative medicine. In theory, the autologous cells derived from patient iPSCs should be immune tolerant by the host without any immune rejections. However, our recent studies have found that even syngeneic iPSC-derived cells can be immunogenic in syngeneic hosts by using a teratoma transplantation model (Nature 474:212-215, 2011). Recently two research groups differentiated the iPSCs into different germ layers or cells, transplanted those cells to the syngeneic hosts, and evaluated the immunogenicity of those cells. Both of the two studies support our conclusions that some certain but not all tissues derived from iPSCs can be immunogenic, although they claimed either "negligible" or "lack of" immunogenicity in iPSC derivatives (Nature 494:100-104, 2013; Cell Stem Cell 12:407-412, 2013). To test the immunogenicity of clinically valuable cells differentiated from human iPSCs are emergently required for translation of iPSC technology to clinics.

Objective:To explore the research status of artificial intelligence in nursing in China, so as to provide reference for conducting research domestically.Methods:The relevant literature collected from January 1, 2003 to May 1, 2023 was searched on China National Knowledge Infrastructure, WanFang Data, and VIP. CiteSpace and VOS viewer were used to visually analyze the research status, hotspots, and frontiers of artificial intelligence in nursing in China from the aspects of annual publication volume, region, institution, author, high-frequency keywords, and emerging words.Results:A total of 494 articles were included. In terms of publication volume, domestic research showed an overall upward trend, with publishing institutions mostly concentrated in economically developed and medically advanced regions. The authors of the articles often collaborated with research groups, with a co-authorship rate of 81.17% (401/494), but there was relatively little collaboration between groups. Research hotspots were focused on the application of artificial intelligence in geriatric nursing, rehabilitation nursing, Operating Rooms, and drug formulation, with a majority of research related to robots.Conclusions:The research enthusiasm in related fields in China is currently on the rise. Research on artificial intelligence in nursing management, nursing education, and psychological nursing can be strengthened, and the application of artificial intelligence can be enriched. At the same time, research institutions and personnel should strengthen mutual cooperation, and relevant national departments should improve laws and regulations to promote the vigorous development of this research field.

Objective:To analyze the current research status of ideological and political education content in domestic nursing courses and facilitate nursing education reform.Methods:Using purposeful sampling, 25 exemplary cases of ideological and political education in nursing courses from Xinhua Net were selected. NVivo 12 software was employed for content analysis, summarizing the ideological and political elements, carriers of these elements, and types of integration methods in nursing courses.Results:Nursing educators have thoroughly explored ideological and political elements, with the most attention given to professional ethics, though less focus was placed on personality development. A variety of carriers for ideological and political elements were utilized, with practical experience being the most common, but there was a lack of integration with policy and regulations. Various integration methods were applied, with interactive methods being the most frequently used, while practical approaches were less common.Conclusions:Future nursing education should emphasize fostering students' sense of national identity and focus more on personality development. It is important to promote a more balanced use of carriers for ideological and political elements, paying particular attention to policy-related content. The use of information technology in teaching should also be explored to flexibly apply various teaching methods, achieving the subtle integration of ideological and political education within nursing curricula.

Objective: To observe the material basis and mechanism of action of Kai-Xin-San (KXS) in regulating antidepression of neurotrophic factors. Methods: KXS eluted by ethanol on macroporous resin was prepared. The antidepressive effect of different components was compared by tailing suspension test and forced swimming test of mice. The levels of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in hippocampus were determined by ELISA. The rat astrocyte glioma C6 cell line and the rat adrenal pheochromocytoma PC12 cell line were used to evaluate the effects of different ethanol elution sites on the expression of NGF and BDNF and the differentiation of PC12 cells.Results: All of the ethanol elution components from KXS exerted anti-depressive effects by shorting the immobile time of tailing suspension and forced swimming of mice and 70％ ethanol elution components exerted best efficacy. This site also could increase expressions of NGF and BDNF on C6 glioma cell line. The 10％ ethanol elution site had the strongest ability to promote PC12 cell differentiation. Ginsenosides were the main effectuve ingredients for promoting the expression of neurotrophic factors. Conclusion: Regulation of neurotrophic factors might be the prominent action mechanism of KXS exerting anti-depressive effects.

Objective:To explore the mediating effect of unhealthy lifestyle and depressive symptom on the associations between life course factors and aging health.Methods:The study included 6 217 participants (aged ≥45 years) from the China Health and Retirement Longitudinal Study (CHARLS). We used principal component analysis (PCA) and hierarchical clustering analysis (HCA) to divide participants into six subgroups based on 70 life course factors. Five key life course factors were identified based on correlation analysis and their contribution to aging health. Physiological dysregulation (PD) was calculated by using eight biomarkers in the 2015 CHARLS biomarker dataset. Linear regression, logistic regression, and mediation models were used to explore the complex associations of life course subgroups, key factors, unhealthy lifestyle, depression symptom with PD.Results:Life course subgroups were significantly associated with PD after adjusting chronological age and gender ( β: 0.08-0.17, all P<0.05). Life-course subgroups and key factors, including adverse experiences in adulthood and lower education level, were significantly associated with unhealthy lifestyle ( β: 0.04-0.52, all P<0.05). Life-course subgroups and key factors, including childhood trauma, parental health in childhood, adverse experiences in adulthood, and lower education level, were significantly associated with depression symptom ( OR: 1.16-4.76, all P<0.05). Mediation analysis showed that unhealthy lifestyle had partial mediating effect on the association of life course subgroups and key factors, including adverse experiences in adulthood, and lower education levels, with PD (3.1%-3.6%). Depression symptom had partial mediating effect on the association of life course subgroups and key factors, including childhood trauma, adverse experience in adulthood, and lower education level, with PD (6.0%-16.2%). Conclusions:Unhealthy lifestyle and depression symptom has partial mediating effect on the impact of life course factors on aging health. It is important to pay attention to these two modifiable factors while targeting childhood trauma and adverse experience in adulthood.

Pluripotent stem cells (PSCs) can immortally self-renew in culture with a high proliferation rate, and they possess unique metabolic characteristics that facilitate pluripotency regulation. Here, we review recent progress in understanding the mechanisms that link cellular metabolism and homeostasis to pluripotency regulation, with particular emphasis on pathways involving amino acid metabolism, lipid metabolism, the ubiquitin-proteasome system and autophagy. Metabolism of amino acids and lipids is tightly coupled to epigenetic modification, organelle remodeling and cell signaling pathways for pluripotency regulation. PSCs harness enhanced proteasome and autophagy activity to meet the material and energy requirements for cellular homeostasis. These regulatory events reflect a fine balance between the intrinsic cellular requirements and the extrinsic environment. A more complete understanding of this balance will pave new ways to manipulate PSC fate.
