Gene therapy, harnessing the power of CRISPR-Cas9 and/or DNAzyme systems, stands as a pivotal approach in cancer therapy, enabling the meticulous manipulation of genes pivotal to tumorigenesis and immunity. However, the pursuit of precise gene therapy encounters formidable hurdles. Herein, a near-infrared upconversion theranostic nanomachine is devised and tailors for CRISPR-Cas9/DNAzyme systems mediate precise gene therapy. An ingenious logic DNAzyme system consists of Chain 1 (C1)/Chain 2 (C2) and endogenous lncRNA is designed. We employ manganese modified upconversion nanoparticles for carrying ultraviolet-responsive C1-PC linker-C2 (C2P) chain and Cas9 ribonucleoprotein (RNP), with outermost coats with hyaluronic acid. Upon reaching tumor microenvironment (TME), the released Mn2+ ions orchestrate a trifecta: facilitating endosomal escape, activating cGAS-STING signaling, and enabling T1-magnetic resonance imaging. Under near-infrared irradiation, Cas9 RNP/C2P complex dissociates, releasing Cas9 RNP into the nucleus to perform gene editing of Ptpn2, while C1/C2 chains self-assemble with endogenous lncRNA to form a functional DNAzyme system, targeting PD-L1 mRNA for gene silencing. This strategy remodels the TME by activating cGAS-STING signaling and dual immune checkpoints blockade, thus realizing tumor elimination. Our theranostic nanomachine armed with the CRISPR-Cas9/DNAzyme logic systems, represents a resourceful and promising strategy for advancing cancer systemic immunotherapy and precise gene therapy.

ObjectiveTo identify the possible health impact of the 14th five⁃year plan for the development of employment and social security in Deqing County and propose improvement measures through health impact assessment. MethodsBased on the data of Deqing County, stakeholder interviews and Delphi Consultation Method, this study described the current status of employment and social security and analyzed the potential health impacts of implementing the 14th five⁃year plan for the development of employment and social security in Deqing County. ResultsThrough a quick assessment process, the results showed that the implementation of the plan would bring mixed health impacts. Positive impacts included enhanced social security capacity, improved health levels of low-income populations and families, increased convenience of medical treatment, and improved efficiency of health services. Negative impacts included reduced accessibility of digital services for the elderly, increased gap in benefits for retirees, increased risk of discrimination against disabled individuals, increased risks of layoffs and unemployment for vulnerable groups, and increased employment instability for middle-aged and elderly populations. ConclusionThe 14th five⁃year plan for the development of employment and social security in Deqing County will bring a series of positive health impacts, but negative health impacts also warrant attention.

Although the treatment of patients with burns combined with inhalation injury has achieved great success, from the perspective of epidemiology, inhalation injury is still the most common cause of death in mass burns. Such patients often suffered burns of large total body surface area, which is difficult to treat, with airway management as one of the core links. Physical airway clearance technique (ACT) acts on a patient's respiratory system by physical means, to discharge secretions and foreign bodies in the airway, achieve airway clearance, and improve gas exchange. In addition, the technique can prevent or alleviate many complications, thereby improving the clinical outcome of patients with inhalation injury. This article reviews the application of physical ACT in the field of inhalation injury, and to provide decision-making basis for clinical medical staff to choose physical ACT corresponding to the patient's condition.

The types of articles included best practices, recommended practices, clinical practice guidelines, expert consensus, evidence summary, systematic review, Meta-analysis and so on. The search period was from the establishment of the database to February 28, 2023. Two researchers independently evaluated the methodological quality of the article, extracting and summarizing the best evidence.Results:A total of 15 articles were included, including 3 clinical practice guidelines, 9 expert consensuses, and 3 systematic reviews. A total of 30 pieces of evidence were summarized from 8 aspects, including home assessment, self-protection management, diet management, psychological cognition management, exercise management, medication management, health education, and follow-up and seeking medical advice.Conclusions:The best evidence for home self-management in MM patients is comprehensive and can provide reference for clinical workers to develop intervention plans. It is recommended that medical and nursing staff develop personalized home self-management plans based on specific clinical scenarios and patient lifestyle habits.

Objective:To explore the current situation of hypoglycemia fear of elderly patients with type 2 diabetes mellitus (T2DM) in the community, identify different types of hypoglycemia fear among elderly T2DM patients in the community by latent profile analysis, and analyze its influencing factors, so as to provide reference for formulating intervention measures.Methods:From February to April 2023, convenience sampling was used to select 300 elderly T2DM patients from three community health service centers in Shunqing District, Nanchong City, Sichuan Province as the research subject. The self-designed General Information Questionnaire, the Chinese Version Hypoglycemia Fear Survey-Ⅱ (CHFS-Ⅱ), and the Summary Diabetes Self Care Activities (SDSCA) were used to investigate the patients, and the latent profile of hypoglycemia fear was analyzed. Binary Logistic regression was used to analyze the influencing factors of different latent categories of hypoglycemic fear in elderly T2DM patients in the community.Results:A total of 300 questionnaires were distributed, and 290 valid questionnaires were collected, with an effective response rate of 96.7% (290/300). Among 290 elderly T2DM patients in the community, the hypoglycemia fear could be divided into two latent categories, including the "moderate worry-normal coping" group ( n=134) and the "high fear-cautious behavior" group ( n=156). The binary Logistic regression showed that marital status, whether there were complications of diabetes, treatment plan and self-management were the factors influencing the latent categories of elderly T2DM patients in the community, and the difference was statistically significant ( P<0.05) . Conclusions:There are classification characteristics of hypoglycemic fear levels in elderly T2DM patients in the community. Community medical and nursing staff should early identify patients in the "high fear-cautious behavior" group, regularly carry out targeted hypoglycemic health education and psychological intervention, reduce their hypoglycemic fear, and improve their quality of life.

Hepatic stellate cells (HSCs) represent a significant component of hepatocellular carcinoma (HCC) microenvironments which play a critical role in tumor progression and drug resistance. Tumor-on-a-chip technology has provided a powerful in vitro platform to investigate the crosstalk between activated HSCs and HCC cells by mimicking physiological architecture with precise spatiotemporal control. Here we developed a tri-cell culture microfluidic chip to evaluate the impact of HSCs on HCC progression. On-chip analysis revealed activated HSCs contributed to endothelial invasion, HCC drug resistance and natural killer (NK) cell exhaustion. Cytokine array and RNA sequencing analysis were combined to indicate the iron-binding protein LIPOCALIN-2 (LCN-2) as a key factor in remodeling tumor microenvironments in the HCC-on-a-chip. LCN-2 targeted therapy demonstrated robust anti-tumor effects both in vitro 3D biomimetic chip and in vivo mouse model, including angiogenesis inhibition, sorafenib sensitivity promotion and NK-cell cytotoxicity enhancement. Taken together, the microfluidic platform exhibited obvious advantages in mimicking functional characteristics of tumor microenvironments and developing targeted therapies.
