ObjectiveTo evaluate the clinical efficacy and safety of Wenshen Yangxue decoction combined with endometrial microstimulation in the treatment of infertile patients with polycystic ovary syndrome （PCOS， syndrome of kidney-Yang deficiency and blood stasis）. MethodsA randomized， positive-drug parallel-controlled， open-label clinical study was conducted. A total of 240 infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis who met the inclusion and exclusion criteria were randomly assigned into 4 groups， with 60 patients in each group. The control group was treated with clomiphene citrate （50-100 mg·d^-¹， orally for 5-10 consecutive days） for ovulation induction. On the basis of the therapy in the control group， the Wenshen group was additionally treated with Wenshen Yangxue decoction （250 mL， warm oral administration， twice daily， in the morning and evening）， and the stimulation group received endometrial microstimulation during the early follicular phase. The combined group was treated with clomiphene citrate plus Wenshen Yangxue decoction （at the same dosages as aforementioned） and endometrial microstimulation. The course of treatment for all the groups was 3 menstrual cycles. The pregnancy rate， ovulation status， sex hormone levels， glucose metabolism indicators， coagulation function， endometrial thickness， traditional Chinese medicine （TCM） symptom scores， and adverse reactions were observed in each group. ResultsA total of 239 patients were included in the final analysis， with 59 patients in the Wenshen group and 60 patients in each of the other three groups. The pregnancy rates were 43.3%（26/60） in the combined group and 32.2%（19/60） in the Wenshen group， both significantly higher than that （10%） in the control group （χ²=17.56，P<0.01）. Compared with the control group， the combined and Wenshen groups had increased mature follicle rates （P<0.01）， while the Wenshen group showed a decreased luteinization rate （P<0.05）. All the groups exhibited significant reductions in TCM symptom scores after treatment， and the Wenshen and combined groups had lower scores than the control group （P<0.01）. No statistically significant difference was found in the incidence of adverse events among the four groups， and all the adverse events were mild. ConclusionWenshen Yangxue decoction combined with endometrial microstimulation can alleviate the TCM symptoms of infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis， promote follicular maturation and ovulation， increase the cumulative pregnancy rate， and has good safety. It can provide new clinical evidence for the integrated traditional Chinese and Western medicine treatment of PCOS infertility.

Objective:To construct and evaluate a training program for cardiovascular nurse specialists based on a core competency framework.Methods:Among 61 trainees participating in the first training class for cardiovascular nurse specialists organized by a provincial nursing society, a training program focusing on the nine core competencies for cardiovascular nurse specialists was implemented, which consisted of 4-week theoretical and 4-week practical training. The effectiveness of the training program was evaluated using the Kirkpatrick model. Data analyses were performed by using SPSS 26.0. Categorical data were presented as the number of cases; continuous variables in normal distribution were expressed as mean±standard deviation; and continuous variables in non-normal distribution were presented as median (interquartile range) and compared using non-parametric tests.Results:At the reaction level, the satisfaction rates of trainees with the theoretical and practical sections of the training program were 98.36% (60/61) and 95.08% (58/61), respectively. At the learning level, the comprehensive assessment score of the trainees was (83.01±3.39) points, and all of them successfully obtained their completion certificates, with a pass rate of 100.00% (61/61). At the behavior level, the core competencies for cardiovascular nurse specialists were significantly improved after training [the total score increased from 291.00 (254.00, 334.25) to 410.50 (354.50, 433.00), P<0.001]. At the results level, at six months after training, there were significant increases in the number of participants engaging in cardiovascular care practices, clinical nursing education and guidance, leadership roles, and research projects within their units as well as the number of individuals achieving career advancement (all P<0.05). Conclusions:The trainees are highly satisfied with the core competency-focused cardiovascular nurse training program, which can improve core competencies and cardiovascular nursing capabilities, expand the scope of cardiovascular nursing services, and foster the sustained advancement of the participants.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective To explore the improving effects of motion sickness acclimatization training methods,namely sinusoidal vertical oscillation stimulation and sinusoidal vertical oscillation stimulation combined with visual virtual reality(VR)swell stimulation,on cognitive performance of individuals with extremely severe motion sickness.Methods A total of 90 individuals with extremely severe motion sickness screened by the Graybiel score during 6 h navigation were randomly divided into vertical group,vertical+VR group,and control group(n=30).The abilities of vigilance,memory,rapid calculation,information processing and visual manipulation were evaluated before and after the acclimatization training using a self-developed cognitive performance evaluation software.Results On the 1st day of training,the numbers of missed targets of the vertical group and vertical+VR group were increased in the vigilance test;the reaction time was prolonged in the short-term memory,rapid calculation,information processing and visual manipulation tasks;and the efficiency of rapid calculation was reduced.After acclimatization training,the numbers of missed targets were reduced to the baseline level in the vertical and vertical+VR groups,and the reaction time in the short-term memory,rapid calculation,information processing and visual manipulation tasks and the efficiency of rapid calculation were improved.Conclusion Motion sickness caused by vertical oscillation stimulation or vertical oscillation combined with visual VR swell stimulation can decrease vigilance,short-term memory,rapid calculation,information processing and visual manipulation abilities.Motion sickness acclimatization training can significantly improve the above cognitive abilities.

Background Grassroots medical and health personnel are an important component of China's public health system, and guaranteeing their physical and mental health will have a profound impact on the development of China's health service. Objective To identify potential influencing factors of occupational stress, anxiety, depression, and insomnia as well as their interactions. Methods In August 2021, a cross-sectional survey was conducted among all the staff (2675 medical and health personnel) at 7 secondary public hospitals and 8 health institutions in Xiong’an New Area of Hebei Province by cluster sampling. Occupational stress, anxiety, depression, and insomnia were evaluated by the Effort-Reward Imbalance Questionnaire (ERI), the Generalized Anxiety Disorder-7 (GAD-7), the Patient Health Questionnaire-9 (PHQ-9), and the Athens Insomnia Scale (AIS). The bnlearn and gmodels packages of R4.2.1 software were used to construct Bayesian networks on work and personal factors-occupational stress- health effects. The Bayesian network model was visualized by Netica32.0. Results Among the 3018 questionnaires distributed, a total of 2675 valid questionnaires were recovered, with an effective recovery rate of 88.63%. The positive rates of occupational stress, anxiety, depression, and insomnia were 51.48%, 62.13%, 62.50%, and 56.37%, respectively in the grassroots medical and health personnel. The positive rate of occupational stress among the medical and health workers varied by age, educational level, and organization type (P<0.05); the positive rate of anxiety varied by age, marital status, and daily working hours (P<0.05); and the positive rates of depression and insomnia varied by gender, educational level, and overcommitment (P<0.05). The final Bayesian network contained 14 nodes and 18 directed edges, and its prediction accuracy was 85.4%. .Job title, daily working hours, overcommitment and exercise directly associated with occupational stress, and other work and personal factors associated with occupational stress indirectly. Occupational stress associated with insomnia directly or indirectly via anxiety. Anxiety and insomnia associated with reporting depression. Conclusion Grassroots medical and health personnel of Xiong'an New Area, Hebei Province report high levels of occupational stress, anxiety, depression, and insomnia. Occupational stress directly or indirectly associates with anxiety, depression, and insomnia. Work and personal factors associate with occupational stress, and associate with anxiety, depression, and insomnia via occupational stress. Occupational stress may be an early warning factor of general work and personal factors affecting anxiety, depression, insomnia, and other mental health problems. Attention should be paid to the assessment and intervention of occupational stress in medical and health personnel to prevent mental health problems.
