Health communication aims to improve public health attitudes and behaviors by propagating health information. It plays an important role in promoting public health literacy and "Healthy China Initiative". The basic theories of health communication include "7 W" and Theory of Planned Behavior. Clinicians with profound medical expertise and a wealth of clinical practice play key roles in the communication, and they hold an unparalleled advantage in health communication by delivering authoritative and trustworthy information to the public. The capacity of health communication among clinicians in the nation is determined by various factors including professional characteristics, policy support, dissemination platforms and pathways, time and effort. Meanwhile, some problems in the research on the health communication capacity of clinicians remain, such as lack of well-established motivation systems, limited dissemination pathways, and imperfect evaluation frameworks. In some regions of China, health communication performance has been considered as part of the professional title evaluation for clinical physicians. Medical institutions and universities have also initiated relevant training and practice programs. It is crucial to improve evaluation frameworks, strengthen training pathways and effectiveness assessment, promote interdisciplinary integration, and enhance the role of clinicians in health communication in the future.

Background China is a major coal producer and consumer country in the world. Coal workers' pneumoconiosis (CWP) is a primary factor endangering the occupational health of coal miners. Research on the disease burden of CWP and its changing trend is significant for disease prevention & control and associated policies. Objective To analyze the disease burden of CWP in China from 1990 to 2021 and its changing trend, and predict the disease burden from 2022 to 2035. Methods Using the Global Burden of Disease Study (GBD) database of 2021, numbers ofincident cases, prevalent cases, deaths, and disability-adjusted life years (DALYs) as well as crude and age-standardized rates of CWP in China were retrieved. Linear regression model was used to calculate the estimated annual percentage change (EAPC) of the age-standardized rates. Joinpoint regression model was used to analyze the temporal trend of disease burden and the disease burden of different sexes and age groups, and Bayesian age-period-cohort (BAPC) model was used to forecast the trend of CWP disease burden. Results In 1990, the incident, prevalent, and deaths cases of CWP in China were 3266, 18872, and 1561, respectively, and the DALYs of CWP were 44614.718 person-years. In 2021, the incident, prevalent, and deaths cases of CWP were 3446, 23975, and 1229, respectively, and the DALYs of CWP were 29610.754 person-years. From 1990 to 2021, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP in China all showed a downward trend, with the EAPCs of −3.121%, −2.532%, −4.018%, and −4.268%, respectively. The disease burden of CWP in China was mainly concentrated in the male population. The annual average percent change analysis indicated that each standardized rate showed a fluctuating downward trend in different periods. The BAPC model showed that from 2022 to 2035, the age-standardized rates of CWP in China would continue to decline steadily. In 2035, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP would be reduced to 0.10 per 100000, 0.74 per 100000, 0.03 per 100000, and 0.74 per 100000, respectively. Conclusion The disease burden contributed by CWP in China generally show a downward trend from 1990 to 2021, and it is expected that the age-standardized rates will continue to decline steadily from 2022 to 2035.

Objective:To investigate the application value of 0.9% sodium chloride injection for a balloon catheter in bedside Doppler ultrasound-guided percutaneous dilatational tracheostomy in critically ill patients.Methods:A randomized controlled study was conducted involving 54 critically ill patients who were scheduled for tracheostomy at the Intensive Care Medicine, Jilin Province People's Hospital, from September 2022 to April 2024. These patients were randomly divided into a conventional group ( n = 27) and an ultrasound group ( n = 27) using the random number table method. The conventional group underwent empirical extubation, while the ultrasound group received extubation guided by a balloon catheter filled with 0.9% sodium chloride injection under ultrasound guidance. The following parameters were observed in both groups: duration of operation, incidence of blood oxygen saturation < 90%, incidence of puncturing the endotracheal tube or balloon catheter, distance from extubation site to the incisors, dosage of propofol, length of incision, and amount of bleeding. Results:Both groups of patients successfully completed the procedure on the first attempt, with no significant complications such as extensive bleeding, vascular injury, thyroid damage, or pneumothorax. In the ultrasound group, the incidence of puncturing the endotracheal tube or balloon catheter, duration of operation, and dosage of propofol were 3.7% (1/27), (6.2 ± 1.4) minutes, and 40 (40, 40) mg, respectively, all of which were superior to those in the conventional group [48.1% (13/27), (9.8 ± 2.7) minutes, 80 (70, 80) mg, χ2 = 23.19, t = 6.11, Z = -6.29, all P < 0.05]. The incidence of hypoxemia in the ultrasound group was 0, which was significantly lower than that in the conventional group [29.6% (8/27), P < 0.05]. The distance from extubation site to the incisors in the ultrasound group was 18 (17, 18) cm, which was significantly different from 18 cm of the conventional group ( Z = -2.62, P < 0.05). There were no statistically significant differences in length of incision and amount of bleeding between the two groups ( P = 0.652, 0.878). Conclusion:Performing PDT under bedside Doppler ultrasound guidance with a 0.9% sodium chloride injection-filled balloon catheter in patients requiring mechanical ventilation can reduce procedure duration, lower the incidence of hypoxemia and puncturing of the endotracheal tube or balloon catheter, decrease the use of sedative medications, and enhance the accuracy and safety of the procedure.

Restricted repetitive behaviors (RRBs) are the most characteristic behaviors of autism spectrum disorder. The clinical diagnosis and treatment of RRBs are extremely difficult resulting from its complex and variable etiology, highly heterogeneous clinical manifestations influenced by multiple factors (sleep quality, gastrointestinal health, age and gender), lack of precise diagnostic criteria and low effectiveness of current clinical interventions. This article mainly reviews the recent related studies on RRBs and discusses the challenges and progress in clinical diagnosis and treatment of RRBs so as to provide new ideas for future clinical diagnosis and treatment.

Thyroid-associated ophthalmopathy(TAO)is an autoimmune disease whose etiology and pathogenesis have not yet been clarified.It is generally believed that its occurrence is the result of a combination of immune,genetic,envi-ronmental,and other factors.In recent years,scholars have paid more attention to the influence of microorganisms on TAO,and they found that alterations of the ocular surface and intestinal flora can stimulate the immune system to generate a series of immune responses,which induces autoimmune responses to TAO.The"gut-eye axis"may be an important fac-tor involved in the development of TAO.The intestinal flora and its metabolites may affect ocular tissues through blood cir-culation and the lymphatic system.This interaction between the gut and eye axis may affect the occurrence and develop-ment of TAO through various pathways,including migration of immune cells,cross immune reactions,and metabolite cir-culation.This article reviews the research progress on the correlation between alterations of the ocular surface and intesti-nal flora and TAO and explores the possible mechanisms of the flora involvement in the development of TAO,providing new ideas for the diagnosis and treatment of TAO.

Osteoporosis （OP） is a skeletal metabolic disease characterized by bone loss and destruction of bone microstructure. Changes in estrogen levels are not the only pathogenic factors for the occurrence and development of OP. MicroRNA （miRNA） plays an important regulatory role in cells. The complementary sequences of miRNA and targeted mRNA combine to inhibit the expression of targeted mRNA through post-transcriptional regulation， forming a complex regulatory network. Research suggests that miRNA is closely related to the occurrence and development of various diseases， including inflammatory diseases， metabolic diseases， and cancer. Targeted mRNA participates in post-transcriptional gene expression regulation in OP， mainly regulating the balance among bone construction， bone resorption， and osteoblast differentiation. Therefore， miRNA-based gene therapy is a rapidly developing disease treatment strategy. Traditional Chinese medicine can improve bone metabolism by intervening in miRNA differential expression to target and regulate osteogenic/osteoclast differentiation. This article summarized the targeting effects of miRNAs in physiological and developmental processes such as bone cell proliferation， differentiation， survival， and apoptosis， reviewed and classified their mechanisms of action and targets， and sorted out the current treatment methods of traditional Chinese medicine for preventing and treating OP and drugs that exert bone protective functions through miRNAs. This review is expected to provide theoretical reference and research guidance for future research on OP treatment by regulating miRNA.

ObjectiveTo compare the effectiveness and mechanism of Xiangzhu Fanggan Formula （香术防感方） by sniffing and nasal drops for preventing influenza A H1N1flu. MethodsFifty-six BALB/c mice were randomly divided into normal group， model group， zanamivir group， high-concentration sachet group， low-concentration sachet group， high-concentration nasal drops group， and low-concentration nasal drops group， with 8 mice in each group. In the low- and high-concentration sachet groups， 15 g and 30 g of Xiangzhu Fanggan Formula sachet were used for sniffing for 24 h per day； while in the low- and high-concentration nasal drops groups， nasal drops of Xiangzhu Fanggan Formula were given at a concentration of 0.11 and 0.22 g/ml， 20 μl each time， twice a day； in the zanamivir group， zanamivir was given at a concentration of 1.025 mg/ml of 20 μl each time， twice a day； in the normal group and the model group， nasal drops of normal saline were given at 20 μl each time， twice a day. Each group was given prophylactic intervention for 5 days. On day 5， 1 h after the administration of the drug， the mice in all groups except the normal group received 35 μl of 50 LD₅₀ A/PR/8/34/H1N1 viral solution as nasal drops to prepare influenza A H1N1 model mice. The body mass of the mice was recorded and the rate of change of body mass was calculated daily from day 5 to day 9 of the experiment， and the general status was observed. The mice were sampled on day 9， and the lung index and the inhibition rate of lung index were calculated； HE staining was used to detect pathological changes in lung tissues and to score lung tissue lesions； RT-qPCR was used to detect viral load in lung tissues； and ELISA was used to detect secretory immunoglobulin A （sIgA） and serum tumour necrosis factor α （TNF-α） and interleukin 2 （IL-2）， interleukin 6 （IL-6）， and interferon γ （IFN-γ） in the lavage fluid of the upper respiratory tract. ResultsOn days 7， 8 and 9 of the experiment， the rate of change in body mass of mice in the model group significantly lower than that in the normal group at the same time points （P＜0.05 or P＜0.01）. On days 8 and 9 of the experiment， the rate of change in body mass of mice in the zanamivir group and the high-concentration nasal drops group increased when compared with the model group （P＜0.05 or P＜0.01）. Compared with the normal group， mice in the model group had significantly higher lung index， lung tissue lesion score， lung tissue viral load， significantly higher serum TNF-α， IL-6， IL-2， IFN-γ levels， and significantly lower sIgA levels in the upper respiratory lavage fluid （P＜0.01）. Compared with the model group， the lung index and lung tissue viral load reduced， serum IFN-γ， TNF-α， IL-2， IL-6 levels reduced， and sIgA levels increased in the zanamivir group and the high-concentration nosal drops group （P＜0.05 or P＜0.01）； except for low-concentration sachet group， lung tissue lesion scores of the drug intervention groups reduced compared with those of the model group （P＜0.01）. Compared with the zanamivir group， the lung index increased in the low-concentration sachet group and the low- and high-concentration nasal drops groups， and the serum TNF-α and IL-2 levels increased in all Xiangzhu Fanggan Formula intervention groups （P＜0.05 or P＜0.01）. Compared with high-concentration nasal drops group， serum TNF-α and IFN-γ levels elevated in the high-concentration increased group， and lung tissue viral load elevated in the low-concentration nasal drops group （P＜0.05 or P＜0.01）. The lung index inhibition rate was 80.84% in the zanamivir group， 41.61% and 17.90% in the high- and low-concentration sachet groups， and 35.40% and 25.40% in the high- and low-concentration nasal drops groups， respectively. HE staining showed that the lung tissues of the model group showed thickening of alveolar septa， alveolar collapse， and infiltration of inflammatory cells； whereas， in each drug intervention group， the inflammation of the lung tissues of the mice and the damage reduced， and the most obvious improvement was in the zanamivir group and the high-concentration nasal drops group. ConclusionXiangzhu Fanggan Formula by sniffing and nasal drops could both prevent influenza A H1N1 virus infection， with antiviral and anti-inflammatory effects， also could improve the pathological damage of lung tissue， and improve the immunity of respiratory mucosa. The nasal drops may be better than sachets in inhibiting inflammatory response， especially the high-concentration nasal drops showed more effective.

Objective:To analyze the influence of forming direction on the surface characteristics,elastic modulus,bending strength and fracture toughness of printed parts and the relationship between forming direction and force direction,and to provide scientific basis and guidance for the clinical applica-tion of oral denture base resin materials.Methods:The 3D printing technology was used to print denture base resin samples.The shape and size of the samples referred to the current standard for testing conven-tional denture base materials.The samples used for physical performance testing were cylindrical(with a diameter of 15 mm and a thickness of 1 mm)and printed at different angles along the Z axis(0°,45°,90°).Scanning electron microscope was used to observe the microscopic topography of the different sam-ples.The color stability of different samples was observed by color stabilizer.The surface roughness of the samples was analyzed by using surface roughness tester.The Vickers hardness was measured to ana-lyze the hardness of the samples.The samples used for mechanical performance testing were rectangular(elastic modulus and bending strength:A length of 64 mm,a width of 10 mm,and a height of 3.3 mm;fracture toughness:A length of 39 mm,a width of 8 mm,and a height of 4 mm),divided into two groups:W group and H group.The W group was printed from the bottom up along the Z axis with the length × width as the bottom surface parallel to the X,Y axis plane,while the H group printed from the bottom up along the Z axis with the length × height as the bottom surface parallel to the X,Y axis plane.The forming angles of both groups were equally divided into 0°,45°,and 90°.The elastic modulus,bending strength and fracture toughness of different samples were studied through universal mechanical testing machine.SPSS 22.0 software was used for statistical analysis.Results:The microscopic topogra-phy and roughness of different samples were closely related to the printing direction,with significant differences between the 0°,45°,and 90° specimens.The 0° specimens had the smoothest surface(roughness＜1 μm).The surface of the 45 ° specimen was the roughest(roughness＞3 μm).The microhardness of the 0° sample was the best[(196.13±0.20)MPa],with a significant difference com-pared with the 90° sample[(186.62±4.81)MPa,P＜0.05].The mechanical properties of different samples were also closely related to the printing direction.The elastic modulus,bending strength,and fracture toughness of the 45° samples in the W group were the highest compared with the other groups.The results of elastic modulus showed that in the H group,the 45° specimens had the highest elastic mo-dulus,which was significantly different from the 0° and 90° specimens(P＜0.05).The elastic modulus of 0° and 45° specimens in the W group were higher than those in 90° specimens(P＜0.05).The bending strength results showed that there was no significant difference between the specimens from dif-ferent angles in the H group.The bending strength of the 90° specimens in the W group was the smallest,and there was a significant difference between 90° and the 0° and 45° specimens(P＜0.05);And the bendind strength of the 0° and 45° specimens in the W group was significantly higher than that of the 0° and 45° specimens in the H group(P＜0.05).The fracture toughness results showed that the fracture toughness of the H group specimens was lower than 1.9 MPa m1/2,which was specified in the denture base standard.The 45° samples in the W group were the highest,with significant differences compared with the 0° and 90° samples(P＜0.05).And the 90° samples of the W group specimens were lower than 1.9 MPa m1/2.And the fracture toughness of the 45° specimen in the W group was significantly higher than that of all the specimens in the H group(P＜0.05).Conclusion:The 0° samples had rela-tively better physical properties.The 45° samples had the best mechanical properties.But the fracture toughness of specimens(H group and 90° samples of W group)did not yet meet clinical requirements.That indicated that the characteristics of the 3D printing denture base resin were affected by the printing direction.Only when the performance of the printed samples in all directions met the minimum require-ments of the standard,they could be used in clinical practice.

The consensus was authored by National Society of Congenital Heart Diseases. After employing the Delphi process and incorporating literature reviews and expert discussions, seven recommendations were ultimately formulated. The consensus provides a detailed elaboration on the pathoanatomy, pathophysiology, clinical manifestations, diagnostic methods, and surgical treatment approaches for aortic valve diseases in children. It emphasizes that the treatment of aortic valve diseases in children should take into account the needs of growth and development, and recommends surgical strategies for different age groups and types of lesions, including valve plasty, Ross procedure, valve replacement, and balloon dilation. Specifically, aortic valve plasty is recommended for neonates and infants, while surgical options for older children are more diversified. The consensus only discusses isolated aortic valve disease and does not cover cases complicated with other heart malformations
