PCOS is a highly prevalent disease in modern women of gestational age, characterized by infertility. Prevention before onset has been a key focus of national efforts in recent years. This article explored the prevention and treatment plan for polycystic ovary syndrome based on the three-level prevention theory of Academician Wang Qi. Primary prevention: control pathogenic risk factors; secondary prevention: precise screening and life intervention to prevent the formation of dangerous constitution; third level prevention: differentiation of body-differentiation of disease-differentiation of syndrome to achieve the goal of three-level prevention. In the prevention and treatment of PCOS, pre-disease prevention, post disease prevention and cure are tried to achieve, which could provide a truly effective, easy to operate, and applicable three-level prevention and treatment plan for a large population in clinical response to PCOS.

Objective:To explore the impact of health self-focused attention on knowledge, attitude and practice of health management in patients with essential hypertension.Methods:This was a cross-sectional study. A total of 190 patients with essential hypertension were randomly selected from Shanghai Dapuqiao Community Health Service Center to participate in a questionnaire survey from October to December, 2021. The contents of the questionnaire included the general information of the patients, the degree of influence of hypertension on individuals, and the patients′ knowledge and personal cognition of hypertension, self-management behaviors, health self-focused attention, and blood pressure control. SPSS 25.0 and AMOS 24.0 were used to develop a structural equation model for analysis.Results:The recovery rate of questionnaires was 100.0% (190/190). Of the 190 patients, there were 82 males and 108 females with a mean age of (71.2±8.5) years. According to blood pressure, 190 hypertensive patients were divided into blood pressure controlled group ( n=119) and blood pressure non-controlled group ( n=71). There were significant differences in the total scores of hypertension self-management behavior and health self-focused attention between the two groups ( P<0.05). Correlation analysis showed that the degree of influence of hypertension on individuals was negatively correlated with the disease knowledge and personal cognition, and the performance of hypertension self-management behavior ( r=-0.39 and -0.28, P<0.01), while the disease knowledge and personal cognition were positively correlated with the performance of hypertension self-management behavior and health self-focused attention ( r=0.29 and 0.27, P<0.01). Hypertension self-management behavior was positively correlated with health self-focused attention and blood pressure control ( r=0.28 and 0.48, P<0.01), and health self-focused attention was positively correlated with blood pressure control ( r=0.21, P<0.01). The equation model analysis showed that health self-focused attention had a driving effect on patients′ disease knowledge and cognition and self-management behavior. Health self-focused attention significantly affected patients′ mastery of disease knowledge and formation of correct cognition (path coefficient=0.28). In addition, hypertension patients′ disease knowledge storage and internal recognition of prevention and treatment strategies determined their self-management behavior (path coefficient=0.20). On the other hand, the impact of hypertension on patients life, work and economic burden played a negative role in their acceptance of disease management knowledge, formation of correct concepts, and adoption of self-management behaviors with adjustment coefficients of -0.48 and -0.22, respectively. Conclusion:Health self-focused attention may play an initial role in the process of changing the knowledge, attitude and behavior of hypertension patients.

ObjectiveTo explore the correlation between blood stasis constitution （BSC） and diseases based on constitution literature involving “constitution-diseases correlation”. MethodsA comprehensive search was conducted on six Chinese and English electronic databases including CNKI， Wanfang， VIP， SinoMed， PubMed and Embase to find all clinical researches on the correlation between constitution and diseases using the Classification and Identification of Chinese Medicine Constitution standard from April 1st， 2009 to December 31st， 2022， and the participants of the research were BSC related. By analyzing the characteristics of the literature， such as authors， publication institutes， participants， and results， the disease with the highest proportion of BSC distribution or BSC as their risk factors or protective factors were summarized to explore the correlation between BSC and diseases. ResultsTotally 135 clinical studies on diseases highly related to BSC were included， with a total sample size of 71 172 cases.There were 27 keywords in the articles appeared more than 3 times， including the elderly， lumbar disc herniation， coronary heart disease， cardiovascular disease， and endometriosis. In the author's clustering， included studis were mainly from Shenzhen Hospital of Beijing University of Chinese Medicine， Second Affiliated Hospital of Guangzhou University of Chinese Medicine， and Wenzhou Central Hospital. In terms of blood stasis related diseases， 81 studies showed that BSC was the most common type of constitution in the study population， involving 48 disease or morbid states. The diseases and median proportions of BSC with reported literature ≥3 included coronary heart disease （28.8%）， endometriosis （31.3%）， neurocognitive impairment （26.4%）， lumbar disc herniation （26.0%）， ischemic stroke （25.0%）， adenomyosis （34.7%）， and endometrial polyps （25.0%）. Fifty-eight studies found that BSC was a risk factor for disease occurrence，and these diseases reported more than 3 times included hypertension （median OR = 2.956）， type 2 diabetes （median OR = 3.436），osteoporosis （median OR = 5.171）， sudden deafness （median OR = 3.827） and endometriosis （median OR = 5.412）. One study indicated BSC as the protective factor of lateral growth tumor of large intestine （median OR = 0.161）. ConclusionBSC is closely related to circulatory system diseases， urogenital system diseases， and musculoskeletal system diseases.

With the continuous improvement of medical information and intelligence, multi-modal data fusion technology is increasingly widely used in the medical field. Multi-modal data not only has a large quantity, but also has rich information content, which can provide strong support for clinical nursing decision-making. However, due to the uneven level of informatization and intelligence development among medical institutions, the development and application of nursing decision support system is still in a fragmented state. Based on this, this study explores in depth the current application status and challenges faced by multi-modal data fusion in nursing decision support systems, with the aim of providing reference for the design and improvement of nursing decision support system at all levels of medical institutions in the future.

With the continuous advancement of information technology, electronic medical records (EMR) have accumulated vast amounts of clinical data, which can assist nursing staff in making clinical decisions, thereby improving the quality of care, enhancing work efficiency, and promoting patient safety. However, due to varying levels of information technology development across medical institutions, nursing decision support systems (NDSS) remain in a fragmented development stage. This article explores the current application status and existing shortcomings of NDSS based on EMR systems, aiming to provide reference for the design and improvement of NDSS in various levels of medical institutions.

Senile dementia is a disease that gradually develops with age. At present, the etiology, pathogenesis and treatment of senile dementia cannot be completely determined clinically. Therefore, it is extremely necessary to prevent and treat senile dementia from prevention and disease management. For the non-ill people, this article analyzed the susceptible groups of senile dementia from the perspective of TCM constitution, combined with the current prevention plan of Alzheimer's disease, from the aspects of examination, nutritional supplementation, adjustment of work and rest, exercise, etc., early physical fitness prevention targeting populations at different stages was conducted; the early onset of senile dementia is not obvious, and the early prevention of senile dementia can be carried out from various aspects in combination with constitution identification and inspection of senile dementia; for the exact sick population, disease management guidance can be added on the basis of the above aspects to provide definite and feasible recommendations for disease prevention and management of the elderly.

【Objective:】 Using classic moral dilemma cases, this paper investigates the choice tendency of medical students when facing the moral dilemma, and analyzes their cognitive status and characteristics when facing the "moral dilemma", in order to provide effective enlightenment for optimizing the teaching cases of medical ethics. 【 Method:】 771 medical students in Shanghai Jiao Tong University School of Medicine were investigated by electronic questionnaire and SPSS 20.0 for statistical description and statistical analysis. 【Result:】 In the emergency room doctors and transition scenes, medical students tend to the principle of maximum happiness, and in the ring track scene and pedestrian overpass scene, they tend to the principle of deontology; In the loop track scene and pedestrian overpass scene, boys are more inclined to deontological principles than girls, and undergraduates are more inclined to deontological principles than postgraduates, and the difference is statistically significant (P<0.05). 【Conclusion:】 Although medical students have different moral tendencies in different scenes, they generally do not agree with the practice of sacrificing one person to save five people. Especially when more rigorous sacrifice conditions cause greater moral pressure, the vast majority of medical students will tend to the latter between utilitarianism and deontological principles.

ObjectiveTo explore the association between total iron， iron supplements， dietary total iron， heme iron intake and the risk of gestational diabetes mellitus（GDM）. MethodsA total of 668 pregnant women who gave birth in one hospital in Shanghai during January 2020 to July 2021 were included in a retrospective cohort study. Baseline characteristics and data of iron supplements in second trimester were collected through a questionnaire. A simplified dietary frequency questionnaire was used to quantify the food intake in second trimester. Total iron， iron supplements， dietary total iron， and heme iron intake was classified into groups by quintile and median. The association between iron intake from different sources and risk of GDM was determined using logistic regression analysis. ResultsAfter correction for age， family history of diabetes， overweight / obesity before pregnancy， hemoglobin（Hb）in first trimester， energy， carbohydrate energy， protein， and free sugar， it showed no association between total iron intake and risk of GDM （P>0.05）， while elevated risk of GDM among women with high iron supplements intake （OR=1.65； 95%CI： 1.14‒2.39）， and decreased risk of GDM among those with high dietary total iron intake （OR=0.53； 95%CI： 0.35‒0.81）. However， no association was found between heme iron intake and risk of GDM （P>0.05）. ConclusionHigh dietary total iron intake may be a protective factor， while high iron supplements may be a risk factor for GDM. It suggests that pregnant women should carefully choose high-dose iron-containing supplements in the absence of iron deficiency， as dietary iron intake should be the priority.

Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.
