Stoma refers to the channel established by surgery to excrete the excreta in the body, which changes the excretion mode of patients, and has a serious impact on the physiological, psychological, spiritual, social and other aspects of patients. The World Council of Enterostomal Therapists released International Ostomy Guideline (Second Edition) in 2020, covering four aspects, including the education and scope of practice, holistic approach to care, preoperative nursing needs and postoperative nursing needs, and a total of 15 recommendations. This article focuses on the interpretation of eight recommendations on the two aspects of preoperative and postoperative nursing needs, with a view to promoting the reform of clinical practice and providing evidence-based basis for clinical nurses. At the same time, it is suggested that clinical nurses should make targeted transformation according to specific clinical situations to improve the quality of clinical nursing.

Objective:To explore the current status and influencing factors of self-care ability in patients with cystostomy and ileal conduit.Methods:Using the convenient sampling method, a total of 160 patients with cystostomy and ileal conduit who visited the Urostomy Clinic of Peking University First Hospital from October 2021 to March 2022 were selected as the research objects. Patients were surveyed using a general information survey questionnaire, Social Support Rating Scale (SSRS) and Urostomy Education Scale. Spearman correlation analysis was used to explore the correlation between social support and self-care in patients with cystostomy and ileal conduit, and multiple linear regression analysis was used to explore the influencing factors of self-care ability in patients with cystostomy and ileal conduit. A total of 160 questionnaires were sent out, and 157 were effectively collected, with an effective recovery rate of 98.13% (157/160) .Results:The total score of Urostomy Education Scale of 157 patients with cystostomy and ileal conduit was [20.00 (4.00, 21.00) ]. The results of multiple linear regression analysis showed that marital status, comorbidities, stoma and peristomal complications, frequency of follow up in urostomy clinic and objective support were the influenting factors for self-care of patients with cystostomy and ileal conduit ( P<0.05) . Conclusions:Self-care of patients with cystostomy and ileal conduit is related to many factors. Medical staff should strengthen the intervention and management of patients with cystostomy and ileal conduit from multiple aspects such as individual and social function, so as to improve their self-care ability.

Methods: This study enrolled 40 patients with AIS, 20 patients with congenital scoliosis (CS), and 20 patients with spinal degenerative disease (SDD). All patients underwent open posterior surgery in our hospital, and a paravertebral muscle (multifidus muscle) biopsy was performed intraoperatively. This study included many indexes that describe muscle, especially dystrophin staining. The above pathological results were compared among the AIS, CS, and SDD groups. The correlation between the Cobb angle and Nash–Moe classification and the above pathological results was analyzed in patients with AIS. Results: Significant reductions in the dystrophin staining of dystrophin-1 (p<0.001), dystrophin-2 (p<0.001), and dystrophin-3 (p<0.001) were observed in the AIS group than in the CS and SDD groups. The higher the Nash–Moe classification in the AIS group, the more significant the loss of dystrophin-2 (p=0.042) in the convex paraspinal muscles. Additionally, a significantly positive correlation was observed between the reductions of dystrophin-2 on the concave side of the AIS group and Cobb angle (p=0.011). Conclusions Dystrophin protein deficiency in the paraspinal muscles plays a crucial role in AIS formation and progression. The severity of scoliosis in patients with AIS is correlated with the extent of dystrophin loss in the paravertebral muscles. Therefore, dystrophin dysfunction may be relevant to AIS occurrence and development.

Epidermal growth factor receptor (EGFR) gene is one of the most common driving genes in non-small cell lung cancer patients, and immune checkpoint inhibitors (ICIs) have been controversial in the clinical application of non-small cell lung cancer with EGFR mutant. The expression abundance of programmed death ligand 1 (PD-L1) is an important predictor to guide the application of ICIs, and EGFR mutations may affect PD-L1 expression in tumor cells. Recent clinical studies have pointed out that the single drug of ICIs is not effective in patients with EGFR mutation, however, the combination of ICIs combined with chemotherapy and the four drugs proposed in the IMpower150 trial show good clinical benefits. In addition, the safety of ICIs and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) combination model needs to be further clarified.

A wireless wearable sleep monitoring system based on EEG signals is developed.The collected EEG signals are wirelessly sent to the PC or mobile phone Bluetooth APP for real-time display.The system is small in size,low in power consumption,and light in weight.It can be worn on the patient's forehead and is comfortable.It can be applied to home sleep monitoring scenarios and has good application value.The key performance indicators of the system are compared with the industry-related medical device measurement standards,and the measurement results are better than the special standards.

In the past 20 years,near infrared spectrum technology has been widely used in human body monitoring due to its non-invasive and real-time characteristics.Oxygen,as the main metabolic substance of the human body,is consumed the most in brain tissue.In order to prevent complications caused by a decrease in brain tissue oxygen during treatment,the patient's brain tissue blood oxygen saturation needs to be monitored in real time.Currently,most of the clinically used non-invasive cerebral blood oxygen detection equipments use dual wavelengths.Other substances on the detection path will cause errors in the measurement results.Therefore,this article proposes a three-wavelength method based on the basic principle of non-invasive monitoring of cerebral blood oxygen using near-infrared spectrum.The brain tissue oxygen saturation monitoring method of detecting light sources was initially verified through the built system,laying the foundation for subsequent system engineering.

ECG signals and sleep monitoring parameters complement each other and can be used for qualitative diagnosis of sleep apnea syndrome and cardio-related diseases.However,due to the limitations of the instrument volume and the detection environment,it is often challenging to integrate these two functions in practical applications.In this paper,a 12-lead dynamic electrocardiograph integrated with sleep monitoring is designed.The system's volume is reduced by combining the integrated ECG simulation front end with a miniature sensor.The system achieves the extraction,conditioning,and calculation of 12-lead ECG signals and sleep-related parameters and writes the data to a memory card in real time,which offers convenience for users and doctors in the diagnostic process.

This paper explores the interpretation of Jichuan Decoction （济川煎） by tracing its name's origin， exa-mining the original texts of herbs in the decoction within Jingyue's Complete Works（《景岳全书》）， exploring the debate on the sovereign drug of Danggui （Angelica sinensis ［Oliv.］ Diels） and Roucongrong （Cistanche deserticola Y.C. Ma）， and analyzing the historical discussions on the efficacy of the decoction. It is believed that the original meaning of the name Jichuan Decoction （济川煎） refers to its strategy for treating “deficiency constipation”， which can be described as “increasing water to navigating the boat”. Danggui （Angelica sinensis ［Oliv.］ Diels） is considered the sovereign herb for nourishing blood and moistening dryness， while Roucongrong （Cistanche deserticola Y.C. Ma） serves as the minister herb for moistening the intestines and promoting bowel movements. It is concluded by the author that Jichuan Decoction （济川煎） does not primarily focus on warming the kidneys and assisting yang， but rather emphasizes nourishing blood， moistening dryness， and promoting bowel movements. Its main indication is constipation due to deficiency of yin and blood， which is supported by evidence from antiquarian materials.
