Abstract The health literacy level among the elderly in China remains at a low level. The 14th Five-Year Plan for Healthy Aging clearly points out that health literacy promotion projects should be implemented to improve the health literacy level among the elderly. The health literacy promotion strategies for the elderly require individual, social, policy and environmental supports. This article reviewed four types of health literacy promotion strategies for the elderly, including social strategies, lecture-based health education strategies, new media-based health communication strategies and environmental strategies. It also proposed that health education institutions, communities and other parties should work together, take advantage of digital technology and internet, and take various measures simultaneously to improve the health literacy of the elderly.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective:To investigate the mid-to-long term therapeutic effects of allogeneic bone composite prosthesis reconstruction in patients with large bone defects after the resection of distal femoral tumors.Methods:From June 2013 to December 2018, a total of 19 patients with malignant tumors of the distal femur who underwent reconstruction with allogeneic bone composite prosthesis in the Department of Bone Tumor, Shanghai General Hospital were retrospectively collected. There were 10 males and 9 females, aged 22.3±11 years (range, 11-42 years). The mean body mass index was 19.3±3.4 kg/m 2 (range, 14-27 kg/m 2). There were 18 cases of osteosarcoma and 1 case of Ewing's sarcoma. According to Ennecking staging, there were 17 cases of stage IIB and 2 cases of stage III. The intraoperative blood loss and operation time were recorded, and the prosthesis and patient survival conditions and postoperative complications were observed. The limb function was evaluated by the Musculoskeletal Tumor Society (MSTS) 93 function score. Results:All patients successfully completed the operation. The operation time was 187.3±39.8 min (range, 110-260 min), the intraoperative blood loss was 284.9±87.0 ml (range, 200-500 ml), and the blood transfusion volume was 327±213 ml (range, 100-800 ml). The remaining length of the proximal femur was 153.7±26.6 mm (range, 93-190 mm), and the length of allogeneic bone was 84.1±24.6 mm (range, 39-134 mm). Among the 19 patients, 9 patients (47%) achieved bony union with an average healing time of 16.7±4.8 months (range, 10-25 months), and 7 patients had delayed healing with an average healing time of 18.4±4.0 months (range, 15-25 months). The remaining 10 cases were nonunion between allogeneic bone and host bone. All patients were followed up for 80.7±20.2 months (range, 56-121 months). During the follow-up, 3 cases died due to pulmonary metastasis of bone tumors, and the time of death was 57 months, 63 months, and 59 months after surgery, respectively. At the last follow-up, the patient survival rate was 84% (16/19), and the MSTS 93 function score of the 16 patients was (24.3±2.4) points (range, 21-28 points), with an excellent rate of 100% (16/16). Seven patients underwent revision surgery, 3 cases were aseptic loosening, 3 cases were prosthesis stem fracture at the junction of the allograft bone and the host bone, and 1 case was periprosthetic infection, among which the patient with periprosthetic infection had poor local soft tissue conditions due to preoperative radiotherapy, and the infection was controlled after two revision surgeries. Five cases were revised with allogeneic bone composite prosthesis, and 2 cases were revised with short-stem giant prosthesis with cortical steel plate or locking nail. After revision, the remaining length of the proximal femur was 143.4±31 mm (range, 91-175 mm), and the length of the allograft bone was 92.6±26.6 mm (range, 61-123 mm). The 7 revised patients were still in follow-up. There were no cases of pulmonary infection, nerve injury, deep vein thrombosis or other complications after surgery.Conclusion:The survival period of patients after the surgery to reconstruct large bone defects following the resection of malignant tumors at the distal end of the femur using allogeneic bone composite prosthesis is satisfactory, and the limb function is good. However, the incidence of prosthesis complications is high, which can be reconstructed through revision.

Recently, small nucleolar RNAs (snoRNAs) have transcended the genomic "noise" to emerge as pivotal molecular markers due to their essential roles in tumor progression. Substantial evidence indicates a strong association between snoRNAs and critical clinical features such as tumor pathology and drug resistance. Historically, snoRNA research has concentrated on two classical mechanisms: 2'-O-ribose methylation and pseudouridylation. This review specifically summarizes the novel regulatory mechanisms and functional patterns of snoRNAs in tumors, encompassing transcriptional, post-transcriptional, and post-translational regulation. We further discuss the synergistic effect between snoRNA host genes (SNHGs) and snoRNAs in tumor progression. More importantly, snoRNAs extensively contribute to the development of tumor cell resistance as oncogenes or tumor suppressor genes. Accordingly, we provide a comprehensive review of the clinical diagnosis and treatment associated with snoRNAs and explore their significant potential as novel drug targets.

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe₃O₄@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe₃O₄@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe₃O₄@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T₂ magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe₃O₄@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

Objective:To explore the construction and application methods of multicenter bone tumor-specific database.Methods:Experts from multiple centers including Shanghai General Hospital, Shanghai Changzheng Hospital, Zhongshan Hospital, Shanghai Sixth People's Hospital, Ruijin Hospital, Fudan University Shanghai Cancer Center and Shanghai Ninth People's Hospital established a standard dataset for bone tumors through research and discussion. Clinical data will be automatically collected and standardized according to standard fields. A database will be built and a users' interface will be developed to ensure secure data storage, while providing services such as exporting raw data, visualizing statistical analysis, establishing clinical queue research projects, et al. Finally, the bone tumor database will be shared by integrating with the Shenkang's Big Data Platform to achieve multi-center data integration.Results:A standard data set for bone tumors containing 603 fields has been established and published. An automated data collection system for bone tumors has been established, including complete data collection, data collation and visualization functions. The data categories include modules such as patients' electronic case information, laboratory information on blood routine, biochemistry and tumor markers, imaging information, surgery information, pathology information and radiotherapy records. Personal information such as patients' names and ID numbers are desensitized and encrypted and can be exported for further research. From 2015 to 2023, the total number of bone tumor cases collected in the database was 10,789. From 2015 to 2019, 112 cases of the osteosarcoma cohort were retrospectively analyzed for admission, with a statistical 5-year survival rate of 68%.Conclusion:A regional bone tumor specialty big data network and data sharing platform has been established, along with data sharing mechanisms and standards including data standards, security standards, and quality evaluation standards. This provides data and efficient new solutions for the construction of China's bone tumor database, as well as a research and development platform for standardized diagnosis and treatment of bone tumors and new technologies.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.

Objective:To explore the feasibility of using Hirsch index(H index) to evaluate the performance of academic papers published by medical talents.Methods:67 medical talents of Wuxi People′s Hospital Affiliated to Nanjing Medical University were enrolled in the study. The numbers of papers published and citations of these talents which have been included by PubMed, Chinese Citation Database, CNKI, Wanfang, and Baidu Scholar. The H value of these talents was calculated according to the list method proposed by Rousseau R. The H index was compared with the traditional evaluation indexes of scientific research performance, such as the number of papers published, the total number of citations and the average number of citations. Pearson test was used to explore the correlation between H index and traditional evaluation index.Results:The H value of 67 talents ranged from 1 to 14. Pearson test showed that the H index was significantly correlated with the total number of papers, the total number of citations and the average number of citations at the level of 0.01, and their Pearson value was 0.746, 0.932, and 0.648 respectively.Conclusions:As a new scientific research performance evaluation system, the H index is recommended in the evaluation of medical personnel, but it needs further and sustained optimization in terms of database inclusion timespan, research work timespan, and authors ranking limit among others.
