Objective To construct large medical model named by "Huaxi HongYi"and explore its application effectiveness in assisting medical record generation. Methods By the way of a full-chain medical large model construction paradigm of "data annotation - model training - scenario incubation", through strategies such as multimodal data fusion, domain adaptation training, and localization of hardware adaptation, "Huaxi HongYi" with 72 billion parameters was constructed. Combined with technologies such as speech recognition, knowledge graphs, and reinforcement learning, an application system for assisting in the generation of medical records was developed. Results Taking the assisted generation of discharge records as an example, in the pilot department, after using the application system, the average completion times of writing a medical records shortened (21 min vs. 5 min) with efficiency increased by 3.2 time, the accuracy rate of the model output reached 92.4%. Conclusion It is feasible for medical institutions to build independently controllable medical large models and incubate various applications based on these models, providing a reference pathway for artificial intelligence development in similar institutions.

OBJECTIVE: To summarize the methods of ankle hinge position design in the correction of clubfoot deformity by Ilizarov method, and to explore its application value in the prevention of ankle dislocation. METHODS: A retrospective study was conducted including 28 patients with rigid clubfoot deformity (34 feet) who met the selection criteria and admitted between September 2021 and December 2024. There were 19 males and 9 females with an average age of 31.8 years (range, 19-47 years). According to Dimeglio classification, there were 21 feet of degree Ⅲ and 13 feet of degree Ⅳ. The causes were traumatic sequelae in 9 cases, congenital foot deformity in 15 cases, spina bifida sequelae in 1 case, peripheral neuropathy in 1 case, and cerebral palsy sequelae in 2 cases. The malformation lasted from 6 to 46 years, with an average of 29.3 years. All patients were treated with Ilizarov circular external fixator, and the hinge position of ankle joint was planned according to the standard lateral X-ray film of foot and ankle and the principle of Ilizarov limb deformity correction center of rotation angulation (CORA) before operation. The 2008 International Clubfoot Study Group (ICFSG) scoring system was used to evaluate the efficacy. RESULTS: The deformity of rigid clubfoot was completely corrected in all patients, and the patients could walk with plantar weight-bearing, and the ankle weight-bearing walking significantly improved when compared with that before operation. There was no complication such as ankle dislocation, talus impact or extrusion, local skin necrosis, needle tract infection, or numbness of extremities during the correction process. All patients were followed up 5-39 months, with an average of 18.1 months. At last follow-up, according to the ICFSG scoring system, 23 feet were excellent, 10 feet were good, and 1 foot was fair, and the excellent and good rate was 97%. CONCLUSION Designing the position of the ankle hinge according to the principle of CORA can effectively avoid ankle dislocation, talus impingement, tibiotalar joint extrusion, and other ankle adverse events in the process of correcting clubfoot deformity, which has good application value in clinical practice.

This study used the Appraisal of Guidelines Research & Evaluation-Health Systems （AGREE-HS） to demonstratively compare 34 global coronavirus disease-2019 （COVID-19） health systems guidance documents （HSGs） and 6 World Health Organization （WHO） standard HSGs. The comparison involved topic， participants， methods， recommendations， and implementability， with the aim of exploring the characteristics of emergency HSGs. The results showed that the emergency HSGs had an overall average score of 49%， with topic having the highest score， recommendations having the second highest score， and participants having the lowest score. The standard HSGs had an overall average score of 79%， with high scores in all items. The emergency HSGs had lower scores in participants， methods， recommendations， and implementability than the standard HSGs （P<0.001）， while the COVID-19 emergency HSGs developed by the WHO had higher score in topic than the standard HSGs （P<0.05）. Compared with those released by countries， the COVID-19 emergency HSG developed by the WHO showed superiority in all items and overall scores （P=0.000 2）. This indicates that emergency HSGs， represented by the COVID-19 emergency HSG， place equal emphasis on topic and recommendations as standard HSGs but have low requirements in terms of expert participation， evidence support， and comprehensive consideration in the time- and resource-limited context. They have the characteristics of prominent topics， clear purposes， orientation to demand， keeping up with the latest evidence， flexible adjustment， and timeliness， emphasizing immediate implementation effects， weakening long-term effects， and focusing on comprehensive benefits. Additionally， developers， types， and report completeness are important influencing factors.

The scientific rigor and efficacy of methodologies employed in drafting emergency health systems guidance documents （HSGs） are paramount in guaranteeing the quality， reliability， and applicability of HSGs. According to the Appraisal of Guidelines for Research and Evaluation- Health Systems （AGREE-HS）， we demonstratively assessed both global coronavirus disease-2019 （COVID-19） emergency HSGs and World Health Organization （WHO） standard HSGs to uncover the core attributes of methods employed in the development of emergency HSGs. Our evaluation findings revealed that across the five assessment items of AGREE-HS， methods in the 34 emergency HSGs evaluated ranked third， trailing behind topic and recommendations. Notably， criterion 2 （the best available and most contextually relevant evidence is considered） received the highest score， whereas criterion 5 （evidence of cost and cost-effectiveness of the potential options is described） scored the lowest. Compared with the WHO standard HSGs， the COVID-19 emergency HSGs exhibited low scores in methods （P<0.05）， which was reflected in nine criteria （P<0.05）， especially in criteria 1 （systematic and transparent methods are used to identify and review the evidence） and 9 （systematic and transparent methods are used to agree upon the final recommendations）. Among the COVID-19 emergency HSGs， that developed by the WHO achieved higher scores in eight out of all nine criteria， excluding criterion 8 （P<0.05）. The clinically relevant emergency HSGs had higher scores in the criteria 3 （the evidence base is current） and 8 （the rationale behind the recommendations is clear） than other types of emergency HSGs. Collectively， the methodology for developing emergency HSGs， represented by the COVID-19 emergency HSG， underscores evidence orientation and integrates expert consensus. It is characterized by adaptable evidence synthesis strategies， streamlined evidence review protocols， and contextual relevance， all of which are influenced by external， internal， and implementation-specific factors.

The formulation method of emergency health systems guidance （HSG） is crucial， directly impacting the efficiency and effectiveness of responses in emergencies. A scientifically sound， systematic， and easily executable guidance document can assist health institutions at all levels in quickly coordinating resources， standardizing emergency response processes， and safeguarding public health. This study employed the Appraisal of Guidelines for Research and Evaluation for Health Systems （AGREE-HS） to analyze the characteristics of participants in developing emergency HSGs represented by the COVID-19 emergency HSG. The results showed that in the 34 HSGs included in this study， the item participants received the lowest score. Within this item， criterion 1 （diversity of development group） scored the highest （3.13±1.55）， while criterion 5 （prevention of funding agency influence） scored the lowest （1.21±0.47）. There were differences （P<0.05） in measures taken to mitigate funding agency influence between the six standard HSGs developed by the World Health Organization （WHO） and the four emergency HSGs. Additionally， differences （P<0.05） existed in the development group members， background， conflicts of interest， and preventive measures between the six WHO standard HSGs and the 34 emergency HSGs， as well as between the HSGs developed by the WHO and those developed by countries. The participants in developing emergency HSGs were influenced by various factors， including limited time for guideline development， modes of participation， scarce evidence， and uncertainties in expected outcomes. There is a need to downplay extensive requirements concerning the composition of group members， institutional diversity， and conflicts of interest， emphasizing the roles of key participants like government officials and professionals who can provide rapid， practical guidance in emergency situations.

Recommendations， consensus-based syntheses of the best available evidence， constitute the core content of a guideline. This paper analyzes the characteristics of emergency health systems guidance documents （HSGs）， represented by the coronavirus disease-2019 （COVID-19） emergency HSG， regarding the item "recommendations" and its eight evaluation criteria in the Appraisal of Guidelines for Research and Evaluation for Health Systems （AGREE-HS）. The World Health Organization （WHO） standard HSGs were used as reference to explore the characteristics of emergency HSGs that are different from non-emergency HSGs. The results showed that the “recommendations” scored second after “topic” among the five items. Criterion 7 relating to operability scored higher than others among the eight criteria， and criterion 3 dealing with ethical principles scored lower than other criteria. Compared with the standard HSGs， the emergency HSGs showed decreased scores （P<0.05） of the item recommendations and the criteria of this item except criterion 4 concerning equity promotion. Among the HSGs with different developers， those developed by the WHO had higher （P<0.05） scores of recommendations than nationally developed HSGs， as evidenced by criterion 4， criterion 5 involving acceptability to and alignment with sociocultural and political interests， and criterion 8 for updating plans. The HSGs regarding global or country strategy scored higher （P<0.05） on criterion 2 relating to comprehensiveness than those involving specific guidance on clinical or material issues. Overall， the emergency HSGs， represented by the COVID-19 emergency HSGs， differ from the standard HSGs in a number of ways in terms of their recommendations. Emergency HSGs have more condensed content and weaker articulation of expected outcomes. They incline to put more emphasis on updating plans， rather than comprehensiveness or integrative requirements in terms of ethics， equity， and sociocultural and political interests.

The clear definition of the topic in emergency health systems guidance （HSG） ensures the relevance， scientific rigor， and practicality of the guidance， providing a clear direction and a framework for a rapid and effective public health response. This study used the Appraisal of Guidelines for Research & Evaluation-Health Systems （AGREE-HS） to demonstratively evaluate the global COVID-19 emergency HSGs and World Health Organization （WHO） standard HSGs， aiming to explore the characteristics of topic in emergency HSGs. The results showed that in the 34 HSGs included， the item topic received the highest score. Specifically， criterion 4 relating to relevant and applicable factors scored the highest （5.59）， while criterion 3 concerning the prioritization of health system challenges scored the lowest （2.76）. There were differences （P<0.05） in criterion 1 between standard HSGs and overall emergency HSGs， as well as between WHO and national emergency HSGs. Criterion 3 also showed differences （P<0.05） between standard HSGs and emergency HSGs， as well as between WHO and national emergency HSGs. Criterion 4 displayed differences （P<0.000 1） between WHO and national emergency HSGs. No differences were observed in intra-group or inter-group comparisons of different emergency HSG subcategories （P<0.05）. Overall， emergency HSGs represented by the COVID-19 emergency HSG focus on detailing the challenges faced by the health system， including the natures of challenges， affected populations， and other relevant and applicable factors， while aligning with stakeholder concerns. The prioritization is downplayed， with emphasis placed on rapid responses to and flexible handling of urgent issues. Influenced by factors such as the evidence base， phase timing， and effectiveness， the topic setting shows variations.

Guillain-Barre syndrome rarely develops after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and only a few reports exist in China. Guillain-Barre syndrome is an acute and life-threatening condition that requires early diagnosis and treatment. A patient with acute myeloid leukemia underwent allogeneic HSCT for >5 months and gradually developed limb muscle weakness and limited eye movement after coexisting with delayed acute intestinal graft-versus-host disease. After the examination of cerebrospinal fluid and electromyography, the diagnosis of Guillain–Barre syndrome was confirmed. After a high-dose intravenous immunoglobulin (IVIg) treatment, muscle strength gradually recovered, and the prognosis was good.

With the increasing number of cancer patients in China, the lack of hospice communication between medical staff and cancer patients can easily cause doctor-patient conflicts. Facing the special group of cancer patients, by introducing the concept of hospice communication and comparing the current situation of hospice communication of cancer patients at home and abroad, this paper found the shortcomings of hospice communication between medical staff and cancer patients in China. This paper aimed to analyze the influencing factors of cancer patients’ hospice communication from three aspects of medical staff, cancer patients and social and cultural background, summarized the assessment tools and matters needing attention related to hospice communication, so as to provide reference for domestic medical staff to develop relevant tools for hospice communication with cancer patients, and help medical staff to implement more effective hospice communication with cancer patients in the context of tranquil care. It is also conducive to help patients open the topic of death from the perspective of doctors and build an open hospice communication environment that is more in line with national conditions of China.

Objective:To investigate the characteristics of digestive system symptoms and its relation with the time of nucleic acid continuous positive in population infected with severe acute respiratory syndrome coronavirus 2 Omicron variant, and to analyze the abdominal computed tomography (CT) features of patients infected with Omicron variant.Methods:From April 11 to May 23, 2022, a questionnaire survey was conducted in patients infected with Omicron variant admitted to the Shanghai National Convention and Exhibition Center Fangcang Hospital. The questionnaire included basic information, the start time of nucleic acid positive, respiratory symptoms, digestive system syptoms and outcomes, etc.Combined with the clinical data, the relation between digestive tract symptoms and the time of nucleic acid continuous positive were analyzed. Thoracic and abdominal CT were performed for patients with continuous positive nucleic acid results ≥10 d, and the relationship between the abdominal CT imaging characteristics and the time of nucleic acid continuous positive was analyzed. Independent sample t-test and multivariate logistic regression were used for statistical analysis. Results:A total of 4 360 valid questionnaires were collected, including 2 475 males and 1 885 females, with a hospital stay of (6.8±4.9) d. Among the 4 360 patients, 1 979 patients (45.4%) had gastrointestinal symptoms such as loss of appetite, abdominal discomfort or pain, constipation and diarrhea. The time of nucleic acid continuous positive in patients with gastrointestinal symptoms was (7.4±5.5) d, which was longer than that of patients without gastrointestinal symptoms (6.5±3.6) d, and the difference was statistically significant ( t=3.78, P<0.001). During the isolation period in the Fangcang Hospital, the time of nucleic acid continuous positive in patients with complete remission of digestive tract symptoms was shorter than that of patients with no remission of digestive tract symptoms ((7.3±5.2) d vs. (8.5±5.7) d), and the difference was statistically significant ( t=2.25, P=0.025). The results of multivariate logistic regression analysis showed that the combination of gastrointestinal symptoms was an independent risk factor for continuous positive nucleic acid result ≥10 d ( OR=1.316, 95% confidence interval 1.294 to 2.205, P=0.046). Among the 299 patients with continuous positive nucleic acid results≥10 d, 187 cases (62.5%) had gastrointestinal symptoms, and 146 cases (48.8%) had abdominal CT findings of thickening of the gastroduodenal wall, thickening of the small intestinal wall, indistinct mesenteric vessels of the small intestine, and dilatation and pneumatosis of the colon. In patients with continuous positive nucleic acid results ≥10 d, abdominal CT indicated that patients with gastrointestinal imaging changes had a longer time of nucleic acid continuous positive than those without gastrointestinal imaging changes ((16.0±2.8) d vs. (13.0±2.1) d), and the difference was statistically significant ( t=2.62, P=0.009). Conclusions:Digestive system symptoms are common in patients infected with Omicron variant. The time of nucleic acid continuous positive in patients with gastrointestinal symptoms is longer than those without gastrointestinal symptoms. Some patients may have gastrointestinal lesions on abdominal CT.
