Extracorporeal membrane oxygenation (ECMO) is a key continuous extracorporeal life support technology that can partially or completely replace a patient's cardiopulmonary function, thereby winning valuable time for the diagnosis and treatment of the primary disease. With the widespread application of ECMO, the need for transport has increased. However, during transfers, the standard heater unit is often large and inconvenient to carry, while alternative warming measures tend to be ineffective. This frequently leads to complications such as hypothermia or the inability to maintain body temperature, which can seriously affect the patient's prognosis. In response to this challenge, the medical and nursing staff of the critical care medicine department at Zhongda Hospital Affiliated to Southeast University jointly designed an insulation device for ECMO transport pipelines. The device was successfully granted a National Utility Model Patent of China (patent number: ZL 2021 2 0653569.3). It primarily consists of key components such as a heating pad, velcro straps, a cover layer, a backing layer, an electric heating layer, and a wiring plug. Its advantages include portability, the ability to effectively wrap around and warm the ECMO circuit during transit, and a reduction in the incidence of hypothermia-related complications. Furthermore, its transparent material design allows for real-time monitoring of the ECMO system's status, making it both economical and practical.

Extracorporeal membrane oxygenation (ECMO) is an important treatment for extracorporeal cardiopulmonary life support for clinically critical patients. Currently, ECMO tubing is commonly fixed by tie-wraps or tourniquets, which have shortcomings such as easy loosening and potential damage to the tubing. Improper fixation of the catheter can lead to a series of adverse events, such as accidental disconnection of the tubing, rupture of the tubing, tubing folding, and air ingress into the tubing. In order to overcome the above problems, the research team of Zhongda Hospital, Southeast University invented a device for ECMO line fixation and obtained a national utility model patent of China (patent number: ZL 2019 2 2282849.3). The tool is mainly composed of several devices, including a line fixation clamp, a clip fixation device, and a base plate, which is uniquely designed and easy to operate. During ECMO therapy, this device ensures effective stabilization of the ECMO tubing, preventing unexpected incidents due to catheter loosening and facilitating the observation of ECMO catheter insertion markings. Pipeline can be effectively fixed to avoid the occurrence of accidents due to the loosening of the catheter, and at the same time, it is convenient to observe the placement scale of the ECMO catheter. The novelty and uniqueness of the fixation device materials also effectively prevent the occurrence of pressure injuries during its use.

Objective:To analyze the influencing factors of patient loyalty in internet diagnosis and treatment, for references for improving the service quality and promoting the sustainable development of internet diagnosis and treatment.Methods:In November 2023, a simple random sampling method was used to select patients who had received internet diagnosis and treatment as the survey objects and conduct a questionnaire survey on performance expectations, effort expectations, social influence, promotion conditions, price values, patient trust and patient loyalty. By establishing an unified theory of acceptance and use of technology model of influencing factors of patient loyalty in internet diagnosis and treatment, the hypotheses were put forward. The structural equation model (SEM) test and mediation effect test were used to verify the hypothesis path and variable mediation effect, and explore the influencing factors of internet patient loyalty.Results:A total of 1 800 patients were included in this study, including 1 188 patients(66.0%) who received internet diagnosis and treatment≥3 times/month. According to the SEA test, performance expectations ( β=0.296, P<0.001), social influence ( β=0.146, P=0.014), promotion conditions ( β=0.366, P<0.001), price values ( β=0.452, P=0.017), and patient trust ( β=0.459, P<0.001) had a direct positive impact on patient loyalty; Social influence ( β=0.147, P<0.001) and promotion conditions ( β=0.084, P<0.001) had a direct positive impact on patient trust. According to the mediation effect test, patient trust partially mediated the relationship between social influence and patient loyalty ( β=0.071, P=0.018), as well as the relationship between promoting conditions and patient loyalty ( β=0.748, P=0.041). Conclusions:Performance expectations, social influence, promotion conditions, price values, and patient trust had a positive impact on patient loyalty, among which social influence and promotion conditions could enhance patient loyalty by strengthening patient trust. It was suggested that relevant institutions should focus on the service quality of internet diagnosis and treatment, further improve performance expectations, expand social impact, improve promotion conditions and regulate price values, so as to enhance the patient loyalty, promote the wide application and rapid development of internet diagnosis and treatment.

Objective:To explore the influencing factors of patients′ preference for internet medical services and provide references for promoting the development of the service.Methods:From June to July 2023, based on the technology acceptance model and the theory of planned behavior, this study constructed the influencing factor model and its hypothetical path of patients′ preference for using internet medical services (platform, content, method and cost). The stratified sampling method was used to select patients from hospitals in Changzhou city, Yangzhou city and Lianyungang city to conduct a questionnaire survey. The survey contents included the personal basic information questionnaire, the patient preference scales and the influencing factors scales for patient preference for internet medical service utilization. Based on the survey results, structural equation model and mediation analysis were used to test the hypothesis path of the model.Results:A total of 1 961 patients were included in this study. The results of structural equation modeling showed that patients′ behavioral attitudes towards internet medical services affect their preferences for service platforms ( β=0.291), content ( β=0.286), mode ( β=0.275) and cost ( β=0.880), subjective norms affect their preferences for service modes ( β=0.206); perceptual behavior control affects their preferences for service modes ( β=0.109) and cost ( β=0.263). Perceived usefulness played a promoting role in the influence pathways of behavioral attitude on platform ( β=0.473), subjective norm on approach ( β=0.543), and self-evaluation of health status on preference for cost ( β=0.414). Perceived ease of use played a promoting role in the influence pathways of perceived behavioral control on preference for cost ( β=0.301)and age on content ( β=0.215). Conclusions:Behavioral attitudes, subjective norms and perceived behavioral control synergistically affect patients′ preference for internet medical service utilization, among which perceived usefulness and perceived ease of use played a partial mediating role. In the future, internet medical development should optimize the operation of internet medical platform and encourage patients to take the initiative to seek medical treatment; accurately locate patients′ medical needs and improve the internet medical service price system; utilize the radiating and driving role of social relationships to optimize the digital medical recommendation model.

Objective:To explore the effect of "ten needles in the stomach" on sleep perception of patients with spleen-gastric damp-heat insomnia based on the theory of "stomach discord, then sleep restlessness", to provide references for clinical diagnosis and treatment.Methods:The study subjects were 300 patients with insomnia from the sleep department and outpatient department of Shijiazhuang Traditional Chinese Medicine Hospital. According to the random number method, they were divided into the stomach ten needle group, the diazepam group, and the stomach ten needle plus diazepam group, with 100 in each group. Among them, the stomach ten needles group received "stomach ten needles" acupuncture treatment, the diazepam group was given diazepam therapy, and the stomach ten needles plus diazepam group was given diazepam combined with "stomach ten needles" acupuncture treatment. The Pittsburgh Sleep Quality Index (PSQI) scores, the self-rating disease symptom scale (SCL-90) scores, nighttime polysomnography (PSG) monitoring indicators, and the mean sleep latency (MSL) values were compared before and after treatment in the three groups. The difference in clinical efficacy between the two groups were observed.Results:The total effective rate was 94.0% (94/100) in the combined group, 77.0% (77/100) in the diazepam group, and 85.0% (85/100) in the stomach ten needle group. There were significant differences among the three groups ( χ2=11.56, P<0.01). After treatment, the daytime dysfunction, hypnotic drugs, sleep disturbance, sleep efficiency, sleep time, sleep time, sleep quality score and total score of the combined group were significantly lower than those in the diazepam group and the stomach ten needle group ( F=5.70, 3.65, 5.23, 6.37, 3.66, 6.19, 7.54, 6.40, all Ps<0.01); The scores of SCL-90 and MSL were significantly lower than those in the diazepam group and stomach ten needle group ( F=8.97, 7.53, all Ps<0.01). In the combined group, NWAK [(1.36 ± 0.87) times vs. (2.69 ± 1.15) times, (2.11 ± 1.05) times, F=5.88], SOL [(13.62 ± 5.85) min vs. (25.06 ± 9.42) min, (19.78 ± 7.63) min, F=6.49], N1/TST [(5.69 ± 1.09)% vs. (12.65 ± 2.58)%, (8.49 ± 2.45)%, F=5.13], N2/TST [(51.07 ± 10 2.06)% vs. (58.36 ± 2.18)%, (55.61 ± 2.04)%, F=9.86] were significantly lower than those in the diazepam group and stomach ten needle group ( P<0.01), SE [(90.33 ± 2.89)% vs. (85.39 ± 2.75)%, (87.53 ± 2.69)%, F=8.36], TST [(449.32 ± 23.65) min vs. (421.66 ± 25.33) min, (431.26 ± 25.98) min, F=8.26], REM/TST [(23.87 ± 4.52)% vs. (14.52 ± 3.87)%, (18.36 ± 3.25)%, F=5.34], N3/TST [(18.69 ± 2.02)% vs. (10.31 ± 1.64)%, (14.89 ± 1.74)%, F=7.69] were significantly higher than those in the diazepam group and stomach ten needle group ( P<0.01). Conclusion:Based on the "stomach discord, sleep restlessness" theory, the ten needles on the stomach can treat insomnia and improve psychological state and sleep quality, with the functions of clearing the damp and heat of the middle joker, regulating the lifting and lowering of qi in the middle.
