Objective To systematically review international research on health communication, and to provide valuable insights and reference for China's health communication research and practice. Methods This study included 693 articles published from January 2023 to April 2024 in two authoritative academic journals in the field of health communication, ^“Health Communication^” and the ^“Journal of Health Communication^”. A systematic review was conducted on the themes, theoretical foundations, research methods, and populations of international health communication research. Results The findings in this study revealed that international health communication research topics were diverse, with hotspots including social media, health information behavior, health misinformation, stigmatization, trust, and risk perception. The results showed that 34% of the articles were based on theoretical foundations, and 93.3% employed research methods, focusing on adolescents, parents, women, and other key populations. Conclusion Domestic health communication research can expand its perspective from ^“information transmission^” to ^“social interaction^”, innovate theories and methods from ^“single paradigm" to ^“multi-integration^” and shift focus from a ^“mass perspective^” to ^“targeted care^” for the health of all populations. Domestic health communication practice can delve into the localization of social media health communication practices, the comprehensive management of health misinformation, and the critical application of new technologies.

The sustainable utilization and development of marine Chinese medicine are of great significance for protecting marine ecosystems,inheriting traditional Chinese medicine(TCM)culture,and promoting high-quality development of the TCM industry.Through generations of efforts,China has established a solid foundation in marine traditional Chinese medicine(MTCM)research,including the accumulation of traditional application experience,construction of research platforms,professional talent cultivation,establishment of high-level academic exchange platforms,policy support,and industrial environment optimization,with a series of breakthrough achievements.However,challenges persist in sustainable utilization and industrial development,such as unclear dynamic status of marine biological resources(some even depleted),disconnection between research and conservation due to weak awareness,insufficient R&D investment hindering landmark achievements,lack of national-level research platforms,and low industrial scale/intensification.To address these issues,strategic measures should be implemented,including strengthening dynamic monitoring and management of marine Chinese medicine resources,advancing artificial breeding and aquaculture technologies,establishing a national technology innovation center,increasing R&D investment through special funds,innovating research approaches,developing high-value products,and promote the integrated development of the entire industry chain of marine traditional Chinese medicine.Additionally,interdisciplinary collaboration,international cooperation,and public education should be enhanced to achieve effective resource conservation and rational utilization,form a marine traditional Chinese medicine industry cluster with a complete industrial chain,significant driving effect,and concentrated brand effect,ultimately contributing to human health and China's maritime power strategy.

Intraoperative neural monitoring (IONM) combines electrophysiology with anatomy to monitor nerve function during thyroid surgery,and has become an important auxiliary technology for neuroprotection. After more than ten years of development,the technology has been widely applied and popularized in China,promoting the development of a number of new technologies in the industry. Combined with the questionnaire survey data of the Chinese Neural Monitoring Study Group,this paper aims to summarize the clinical effect of IONM technology, the application status and existing problems at home and abroad, and propose the possible future development direction.

Objective:To study the current situation of the operating room nurses′ flourishing, and to explore the mediating role of self-compassion between forgiveness and flourishing, so as to provide a basis for improving the level of flourishing of operating room nurses.Methods:From September to November 2023, a total of 1 182 operating room nurses from 20 hospitals in Henan province were investigated by convenient sampling method. General data questionnaire, the Heartland Forgiveness Scale, Self-Compassion Scale and the Flourishing Scale were used to conduct an online cross-sectional survey. The mediating role of self-compassion in the relationship between forgiveness and flourishing was analyzed.Results:A total of 1 182 valid questionnaires were collected, including 261 males and 921 females. The age ranged from 21 to 54 (33.21 ± 5.72) years. In operating room nurses, the score of the forgiveness was (111.88 ± 18.77) points, the score of the self-compassion was (76.60 ± 10.75) points, the score of the flourishing was (43.48 ± 8.72) points. Forgiveness was positively correlated with self-warmth and flourishing ( r=0.545, 0.590, both P<0.05), forgiveness was negatively correlated with self-cold ( r=-0.365, P<0.05). The flourishing was positively correlated with self-warmth ( r=0.608, P<0.05), and negatively correlated with self-cold ( r=-0.509, P<0.05). self-warmth and self-cold played a mediating role between forgiveness and flourishing. The indirect effects of self-warmth and self-cold were 23.97% and 20.93% of the total mediating effects. Conclusions:The level of flourishing of the operating room nurses is at a relatively high level. Nurses′ forgiveness can affect their flourishing directly as well as indirectly through self-warmth and self-cold.

Objective:To explore the effects of adenosine on learning and memory in rats thromboembolic stroke(TS)and its mechanism based on PI3K/Akt/CREB signaling pathway.Methods:36 male SD rats were randomly di-vided into sham group(Sham),TS group,TS+adenosine(TS+Ade)group and TS+adenosine+Akt inhibitor(TS+Ade+MK-2206)group.Preparation of rat TS model used autologous thrombus intravascular formation method.Mor-ris water maze(MWM)test was used to observe the learning and memory ability of rats.The morphological changes of hippocampal neurons were observed by Nissl staining.The expression of glutamate transporter 1(GLT-1)and glial fi-brillary acidic protein(GFAP)in CA1 region was determined by immunofluorescence.The protein expressions of PI3K,p-PI3K,Akt,p-Akt,CREB and p-CREB were determined by Western blot.Results:Through the rat TS mod-el,adenosine was able to improve the learning and memory ability,improve the hippocampal neuron cell morphological abpormality and vacuolation,nucleolar condensation and other phenomena in rats.Immunofluorescence results showed that GLT-1 and GFAP were co-localized,and adenosine could significantly enhance the fluorescence intensity of GFAP and GLT-1.Western blot results showed that adenosine can enhance the expression of p-PI3K,p-Akt,and p-CREB proteins,but the use of Akt inhibitors can to some extent inhibit the phosphorylation of PI3K,Akt,and CREB.Conclusion:Adenosine may enhance the expression of GLT-1 in astrocytes and increase the clearance of glutamate through activation of PI3K/Akt/CREB signaling pathway,thereby reducing the excitotoxicity and improving recognition and memory function.However,this effect is partially blocked by Akt inhibitors.

En bloc resection of bladder tumor(ERBT),as an innovative procedure for conventional transurethral resection of bladder tumor(cTURBT),has become an important treatment option for non-muscle invasive bladder cancer(NMIBC).Although ERBT has been recommended by international guidelines,its technical standardization,verification of long-term survival benefits and stratification of indications are still the focus of future research.This article first provides an overview of the surgical techniques of ERBT,and then elaborates on the advantages and disadvantages of the three energy sources of ERBT,namely,electrocautery,laser,and Hybridknife.In terms of pathological assessment,current research suggests that the detection of detrusor muscle in surgical specimens can reflect the quality of the surgery.The integrity of pathological specimens and diagnostic consistency have promoted the progress of sub-staging of T1 bladder cancer and have also driven more research on microscopic indicators related to prognosis.Finally,this article reviews whether repeated transurethral resection can be avoided to help optimize individualized treatment for bladder tumor.

BACKGROUND:The cryopreservation technology enables tissues/cells to be stored for a long time in a low-temperature environment while maintaining the integrity of their activity and function,which is of great significance for the construction of cell therapy,tissue engineering and biological sample banks.Cryoprotective agents often contain dimethyl sulfoxide and serum.To avoid the toxic side effects of dimethyl sulfoxide,the complexity of serum components and immune responses,although some finished cryoprotective agents have been marketed,they are faced with many difficulties such as high cost and limited application.Therefore,there is an urgent need to develop a cryoprotective agent with clear components and the ability to solve the above problems.OBJECTIVE:To evaluate the effects of a novel cryoprotectant on cryopreservation efficiency of different tissue and cell sources.METHODS:By applying the novel cryoprotectant as an experimental group with the commercially available and widely used cryoprotectant(control group)to umbilical cord Wharton's jelly tissue,umbilical cord mesenchymal stem cells,umbilical cord blood/peripheral blood mononuclear cells,NK and CIK cells,comparative analyses were conducted in terms of cell morphology,number,viability,surface markers,differentiation potential,and cell-killing toxicity assay before cryopreservation and after resuscitation thawing.We confirmed the cryopreservation effect of the new cryoprotectant and its potential application value.RESULTS AND CONCLUSION:(1)The novel cryoprotectant facilitated the normal growth of cryopreserved Wharton's jelly tissue upon recovery,exhibiting mesenchymal stem cell morphology.No significant differences were observed between the experimental and control groups in terms of cell recovery rate,surface markers,and differentiation potential.(2)There was no significant difference in the number and viability of cells between the experimental group and the control group after cryopreservation of cord blood/peripheral blood mononuclear cells,and the cryo-resuscitated cell numbers and viability of derived NK cells/CIK cells did not show significant difference between the experimental and control groups.(3)For NK cells derived and differentiated from cord blood/peripheral blood mononuclear cells,there was no significant difference in the proportion of CD56+CD16+cell subpopulations between the experimental group and the control group.For CIK cells derived and differentiated from cord blood/peripheral blood mononuclear cells,there was no significant difference in the proportions of CD3+CD8+and CD3+CD56+cell subpopulations between the experimental group and the control group.(4)In terms of cytotoxicity testing,when the effective-target ratio of immune cells and melanoma cell line Mel624 was 20:1,whether it was NK cells/CIK cells derived from cord blood or peripheral blood mononuclear cells,there was no significant difference in the tumoricidal activity of cells between the experimental group and the control group.These findings suggest that the novel cryoprotectant can replace existing commercially available and widely used cryoprotectants,and is applicable to Wharton's jelly tissue,umbilical cord mesenchymal stem cells,umbilical cord blood/peripheral blood mononuclear cells,as well as NK and CIK cells,providing a solid technical foundation for the scaling,standardization,and commercialization of universal cryoprotectants.
