Objective: To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women. Methods: From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model. Results: A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome. Conclusion The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

ObjectiveTo investigate common dyadic coping (CDC) in linking with marital satisfaction and quality of life (QOL) in patients with brain injury and their spouses in a rehabilitation facility by using common fate model (CFM). MethodsFrom October, 2022 to June, 2023, 101 brain injury inpatients and their spouses in Beijing Bo'ai Hospital completed the questionnaire of Dyadic Coping Inventory, Kansas Marital Satisfaction Scale and World Health Organization Quality of Life. ResultsThe level of CDC between patients and their spouses significantly positively correlated with their marital satisfaction for both partners (β = 0.814, P < 0.001), as well as correlated with their quality of life (β = 0.271, P = 0.038; β = 0.481, P < 0.001). For the dimensions of QOL, the physical, psychological, social relationship and environmental dimensions significantly positive correlated with the CDC for the spouses, and only psychological and social relationship dimensions for the patients. ConclusionFacing the stress of brain injury, the level of CDC within couples can positively predict their marital satisfaction and QOL, and effect seems stronger for the spouses. It is advisable to consider both brain injured patients and their spouses as a whole to promote psychological adaptation and improve rehabilitation outcomes.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objective:To investigate the effectiveness of a tiered progressive training model in the standardized residency training of general practice in primary care institutions.Methods:A tiered progression teaching plan was applied for 26 general practice residents who attended the rotation of general practice residency training in Beijing Fangzhuang Community Hearlth Service Center from June 2022 to May 2023. The plan defined the teaching objectives and requirements for different stages, and the Leicester Assessment Package (LAP) and narrative medicine were included in the teaching methods. The effectiveness of the tiered progression training was evaluated through a questionnaire survey on the post competency of general practice residents.Results:There were 12 primary stage residents, 9 intermediate stage residents and 5 advanced stage residents. The post-training scores of general practice residents in all three stages of residents were significantly higher than the pre-training scores ( t=-3.627,-2.073,-5.277,all P<0.05). The scores of basic medical and health services, basic public health services, information utilization ability and management ability, medical knowledge and lifelong learning, interpersonal communication and teamwork, professional quality after six post competency training were significantly higher than those before training in all three stages of residents. The scores of basic medical and health services, basic public health services, medical knowledge and lifelong learning, in primary residents were significantly improved compared with those before training ( t=-3.457,-3.428,-3.063, all P<0.05);the scores of basic public health services, interpersonal communication and teamwork, and professional quality in intermediate residents were significantly higher than those before training ( t=-2.328,-2.100,-1.997, all P<0.05); the scores of basic medical and health services, basic public health services, information utilization ability and management ability, medical knowledge and lifelong learning, interpersonal communication and teamwork, and professional quality in senior residents were significantly higher than those before training ( t=-5.707,-4.542,-2.952,-1.753,-2.705,-2.805, all P<0.05). Conclusion:The application of tiered and progressive training model in the standardized residency training is helpful to improve the post competency of general practice residents.

Objective:To investigate the application effect of the best evidence for prevention of perioperative delirium in elderly patients with hip fracture.Methods:Using the convenient sampling method, a total of 62 elderly patients with hip fractures admitted to the Trauma Department of Provincial Hospital Affiliated to Shandong First Medical University from January to August 2021 were selected as the control group, and 62 elderly patients with hip fractures admitted from September 2021 to April 2022 were selected as the observation group. At the same time, 17 nurses from the same department were selected as the research objects. According to the standard procedures and clinical conversion system application methods of the Evidence Based Clinical Evidence Practice System at the Joanna Briggs Institute in Australia, the best evidences were applied to the prevention of delirium in elderly hip fracture patients during the perioperative period. Before and after the application of evidence, the compliance rates of the review indicators, the scores of knowledge and attitude on prevention of delirium in elderly patients with hip fracture and the occurrence of delirium in patients were compared.Results:After the application of evidence, the compliance rates of review indicators were higher than those before the application, and the differences were statistically significant ( P < 0.05). The knowledge accuracy and attitude scores of delirium prevention in elderly nurses with hip fractures during perioperative period were higher than those before application, and the differences were statistically significant ( P<0.05). The number of delirium cases in the observation group was lower than that in the control group, and the duration of delirium was shorter than that in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The clinical application of the best evidence for perioperative delirium prevention in elderly hip fractures can improve nurses' awareness and attitude towards perioperative delirium prevention in elderly hip fractures, and reduce the occurrence of delirium in patients.

【Objective】 To investigate the effect of trehalose added to M-Sol on platelet preservation at 4℃ in vitro. 【Methods】 Seven bags of ABO homotype concentrated platelets were randomly selected and divided into 7 groups according to storage temperature, preservation medium and trehalose concentration: 22℃+ PRP group, PRP group, M-Sol+ PRP group, M-Sol+ PRP+ 1 g/L trehalose group, M-Sol+ PRP+ 5 g/L trehalose group, M-Sol+ PRP+ 15 g/L trehalose group and M-Sol+ PRP+ 25 g/L trehalose group. PRP group and M-Sol preservation groups were stored at 4℃. Plt, PDW, MPV, maximum aggregation, CD62p positive rate, GLU and LAC concentration were detected on the 1st, 3rd, 5th and 7th day after preservation, and the changes of GLU and LAC concentration within 7 days were calculated. 【Results】 With the extension of preservation time, Plt decreased in all groups, and there was no significant difference among groups at the same time (P>0.05). PDW and MPV increased in all groups. When preserved to the 7th day, the PDW 10.22±0.43(fL) and MPV 8.74±0.40(fL) of M-Sol+ PRP+ 5 g/L trehalose group were the lowest, which was significantly different from that of 22℃+ PRP group (P<0.05). The changes of GLU and LAC concentration within 7 days were the lowest in M-Sol+ PRP+ 5g/L trehalose group, and the change of GLU concentration within 7 days was significantly different from that of 22℃+ PRP group (P<0.05), but not significantly different from that of PRP group (P>0.05). During the preservation period, the maximum aggregation degree of each group decreased gradually. Except for the PRP group, the maximum aggregation degree of the M-Sol+ PRP+ 5g/L trehalose group was the highest(27.29±6.62), which was significantly higher than that of the 22℃+ PRP group on the 7th day after preservation (P<0.05). On the 7th day after preservation, the positive rate of CD62p in M-Sol+ PRP+ 5g/L trehalose group was the lowest(15.46±2.46), and there was significantly different compared with other groups (P<0.05). 【Conclusion】 Adding appropriate concentration of trehalose to M-Sol can inhibit platelet activation at 4℃ and reduce platelet storage lesion.

Lung is one of the most sensitive target organs of human beings under the shock waves. Due to its serious injury, rapid development and high mortality, blast lung injury has been a widely concerned research topic in the field of military medicine. In the normal physiological state, the body is in a dynamic balance between pro-inflammaton and anti-inflammation, oxidation and anti-oxidation, promoting apoptosis and inhibiting apoptosis. While blast lung injury breaks the balance and causes physiological, biochemical and pathological changes in the body, seriously leading to acute respiratory distress syndrome and multiple organ dysfunction syndrome, and eventually the mortality. So far, the researches on blast lung injury mainly involve damage model, pathogenesis, pathological changes, intervention treatment and so on, which has achieved great research findings. In the review, the authors summarize the progress of molecular mechanism for blast lung injury from the perspective of inflammatory reaction, oxidative stress, apoptosis and so on, which may promote the discovery of new targets for the diagnosis, treatment and rehabilitation intervention of blast lung injury.
