Pulmonary hypertension (PH), characterized by diverse etiologies and intricate pathological mechanisms, is a complex cardiopulmonary vascular disorder featuring high morbidity and mortality. Percutaneous pulmonary artery denervation (PADN) represents an emerging interventional treatment method, which shows good prospects in the clinical practice of PH. The PADN has attained preliminary achievements in terms of safety and efficacy. Nevertheless, its long-term prognosis, the characteristics of the appropriate patient populations, and the optimization strategies combined with targeted pharmacotherapy remain to be further explored. This article reviews the current clinical applications of PADN as well as the challenges it confronts.
Objective
To review the application progress of non-biological meshes for breast reconstruction (BR).
Methods
The related home and abroad researches in BR were reviewed and summarized.
Results
Non-biological meshes can be divided into degradable and nondegradable. The former has many types, whether its degradation rate can match with the grow rate of repair tissue will significantly affect the wound healing and tissue intergradation. TiLOOP, on behalf of the latter, has a good postoperative performance due to its nano TiO2 layer, lightness and flexibility. Non-biological meshes have been gradually used to cover and fix implant in BR. Compared with biological meshes, non-biological meshes are cheaper and have a more positive postoperative performance generally, but definite comparison can’t be concluded due to the limited data.
Conclusion
As non-biological meshes are applied to BR preliminarily, their effectiveness are still needed to be observed further.

Artificial intelligence (AI) has been widely used in all walks of life, including healthcare, and has shown great application value in the auxiliary diagnosis of pulmonary nodules in the medical field. In the face of a large amount of lung imaging data, clinicians use AI tools to identify lesions more quickly and accurately, improving work efficiency, but there are still many problems in this field, such as the high false positive rate of recognition, and the difficulty in identifying special types of nodules. Researchers and clinicians are actively developing and using AI tools to promote their continuous evolution and make them better serve human health. This article reviews the clinical application and research progress of AI-assisted diagnosis of pulmonary nodules.
Glucocorticoids are the first-line therapy of many neurological disorders, with the treatment regimen varying across types and characteristics of neurological disorders. This article reviews the national and international guidelines and expert consensuses in the past decade on glucocorticoids treatment for neurological disorders, and summarizes recommendations from the latest Chinese guidelines and consensuses. In summary, the most frequently used pulse therapy of glucocorticoids in China is intravenous infusion of high-dose (usually 1000 mg/d) methylprednisolone in a short period (often <5 d), followed by gradual tapering, bridging with oral prednisone or direct discontinuation. The treatment regimen for children and juveniles is similar to that for adults but the dose is adjusted by body weight. Pharmacodynamics of glucocorticoids should be considered for the treatment of perinatal women. To provide appropriate glucocorticoids treatment for patients with neurological disorders, clinicians should fully understand features of each neurological disorder and clinical characteristics of individual patient.
Objective
To promote the clinical application of parenteral and enteral nutrition preparations in hospitalized patients.
Methods
Domestic and foreign articles about parenteral and enteral nutrition support were enrolled to make a review.
Results
Nowadays, parenteral and enteral nutrition played an important role in the medical treatment of perioperative and critically ill patients. Rational nutrition support could improve the condition of patients with nutritional risk and result in better clinical outcomes. Different enteral nutrition formulations should be used according to the diseases. Supplementally parenteral nutrition may also be useful in combination with enteral nutrition to reach the required intake targets. We should pay attention to the application of glucose, lipid emulsion, amino acids, vitamins, and so on, when performed parenteral nutrition support.
Conclusion
It is necessary to standardize parenteral and enteral nutrition support in the work of clinical practice, including the application of nutrition support and selection of nutrition preparations.
Patient-reported outcome (PRO) has been paid increasing attention in lung cancer surgery. It has gradually become an important outcome indicator in clinical research of lung cancer surgery and an important tool for symptom management. Commonly used lung cancer-specific PRO measurement tools include: Lung Cancer Symptom Scale, European Organization for Research and Treatment of Cancer-Core Quality of Life Questionnaire and Lung Cancer module, Functional Assessment of Cancer Therapy-Lung, MD Anderson Symptom Inventory-Lung Cancer module, Postoperative Symptom Scale for Lung Cancer Patients, and Perioperative Symptom Assessment for Lung Surgery. The application of lung cancer-specific scales lacks authoritative implementation norms in the field of lung cancer surgery in terms of scale selection, data collection, and outcome application. This review aimed to analyze the current status of application of PRO scales in lung cancer surgery.
As a low-load physiological monitoring technology, wearable devices can provide new methods for monitoring, evaluating and managing chronic diseases, which is a direction for the future development of monitoring technology. However, as a new type of monitoring technology, its clinical application mode and value are still unclear and need to be further explored. In this study, a central monitoring system based on wearable devices was built in the general ward (non-ICU ward) of PLA General Hospital, the value points of clinical application of wearable physiological monitoring technology were analyzed, and the system was combined with the treatment process and applied to clinical monitoring. The system is able to effectively collect data such as electrocardiogram, respiration, blood oxygen, pulse rate, and body position/movement to achieve real-time monitoring, prediction and early warning, and condition assessment. And since its operation from March 2018, 1 268 people (657 patients) have undergone wearable continuous physiological monitoring until January 2020, with data from a total of 1 198 people (632 cases) screened for signals through signal quality algorithms and manual interpretation were available for analysis, accounting for 94.48 % (96.19%) of the total. Through continuous physiological data analysis and manual correction, sleep apnea event, nocturnal hypoxemia, tachycardia, and ventricular premature beats were detected in 232 (36.65%), 58 (9.16%), 30 (4.74%), and 42 (6.64%) of the total patients, while the number of these abnormal events recorded in the archives was 4 (0.63%), 0 (0.00%), 24 (3.80%), and 15 (2.37%) cases. The statistical analysis of sleep apnea event outcomes revealed that patients with chronic diseases were more likely to have sleep apnea events than healthy individuals, and the incidence was higher in men (62.93%) than in women (37.07%). The results indicate that wearable physiological monitoring technology can provide a new monitoring mode for inpatients, capturing more abnormal events and provide richer information for clinical diagnosis and treatment through continuous physiological parameter analysis, and can be effectively integrated into existing medical processes. We will continue to explore the applicability of this new monitoring mode in different clinical scenarios to further enrich the clinical application of wearable technology and provide richer tools and methods for the monitoring, evaluation and management of chronic diseases.
