Objective:To investigate the impact of early removal of nasogastric tubes on functional recovery after total gastrectomy for gastric cancer patients, to provide scientific evidence for enhanced recovery after surgery strategies in gastric cancer.Methods:A retrospective cohort study was conducted on 102 gastric cancer patients who underwent total gastrectomy at Beijing Friendship Hospital affiliated with the Capital Medical University from March 2018 to July 2022. Patients were divided into two groups based on whether the gastric tube was removed within 24 hours post-operation: the early removal group (within 24 hours, 55 patients) and the non-early removal group (beyond 24 hours, 47 patients). The recovery outcomes, including time to first flatus, time to fluid intake, length of hospital stay, and the incidence of postoperative complications, were compared between the two groups. Non-normally distributed data were expressed as M( Q1, Q3) and compared using the Wilcoxon rank-sum test. Categorical data were expressed as frequencies or percentages and compared using the chi-square test or Fisher′s exact test. To minimize the impact of potential confounders, multivariable linear regression and logistic regression analyses adjusted for propensity scores were further employed to compare quantitative and qualitative data between the groups. Statistical analyses were performed using R software. Results:The exhaust time, water intake time, and hospital stay in the early removal group were 3.0(2.0, 3.5) days, 4.0(3.0, 5.0) days, and 7.0(7.0, 8.0) days, respectively, while those in the non-early removal group were 4.0(3.0, 5.0) days, 6.0(5.0, 7.0) days, and 8.0(7.5, 11.0) days, respectively. Statistically significant differences were observed between the two groups ( P<0.05). However, there was no significant difference in the incidence of postoperative complications between the two groups (5.45% vs 17.02%, P=0.060). Propensity score-adjusted regression analysis suggested that early tube removal might reduce the risk of postoperative complications ( P=0.042). Conclusion:Early removal of nasogastric tubes can significantly accelerate functional recovery after total gastrectomy for gastric cancer patients and may reduce the risk of postoperative complications, providing important clinical guidance for enhanced recovery after surgery management in gastric cancer.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

The chemical constituents from the stems and leaves of Cratoxylum cochinchinense were isolated and purified using silica gel, ODS gel, and Sephadex LH-20 gel column chromatography, as well as preparative HPLC. The chemical structures of all isolated compounds were identified on the basis of their physicochemical properties, spectroscopic analyses, and the comparison of their physicochemical and spectroscopic data with the reported data in literature. As a result, 21 compounds were isolated from the 90% ethanol extract of the stems and leaves of C. cochinchinense, which were identified as cratocochine(1), 1-hydroxy-3,7-dimethoxyxanthone(2), 1-hydroxy-5,6,7-trimethoxyxanthone(3), ferrxanthone(4), 3,6-dihydroxy-1,5-dimethoxyxanthone(5), 3,6-dihydroxy-1,7-dimethoxyxanthone(6), 1,2,5-trihydroxy-6,8-dimethoxyxanthone(7), securixanthone G(8), gentisein(9), 3,7-dihydroxy-1-methoxyxanthone(10), pancixanthone B(11), garcimangosxanthone A(12), pruniflorone L(13), 9-hydroxy alabaxanthone(14), cochinchinone A(15), luteolin(16), 3,5'-dimethoxy-4',7-epoxy-8,3'-neolignane-5,9,9'-triol(17), N-benzyl-9-oxo-10E,12E-octadecadienamide(18), 15-hydroxy-7,13E-labdadiene(19), stigmasta-4,22-dien-3-one(20), and stigmast-5-en-3β-ol(21). Among these isolates, compound 1 was a new xanthone, compounds 2-5, 7, 8, 12, and 16-21 were isolated from the Cratoxylum plant for the first time, and compounds 11 and 13 were obtained from C. cochinchinense for the first time. Furthermore, all isolated compounds 1-21 were appraised for their anti-rheumatoid arthritis activities by MTS method through measuring their anti-proliferative effect on synoviocytes in vitro. As a result, xanthones 1-15 displayed notable anti-rheumatoid arthritis activities, which showed inhibitory effects on the proliferation of MH7A synoviocytes with the IC_(50) values ranging from(8.98±0.12) to(228.68±0.32) μmol·L~(-1).

Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.

ObjectiveTo explore the common syndromes of patients with cerebral infarction in rural areas of eastern Henan based on latent structure model and factor analysis,and provide reference for clinical differentiation of cerebral infarction. MethodThe data samples of patients with cerebral infarction in rural areas in eastern Henan were preprocessed. With Lantern 5.0 of latent structure method and LTM-EAST algorithm of two-step latent tree analysis, the manifest variable latent structure model of related symptoms was built to interpret different latent nodes, and common syndromes of cerebral infarction were obtained via comprehensive cluster analysis. SPSS 20.0 was used for factor analysis and cluster analysis of related symptoms to infer the distribution of syndrome types. ResultThe data of 888 patients with cerebral infarction were included, involving symptoms, tongue and pulse (88 in total). The 65 symptoms with a frequency of ≥5% were constructed into a latent structure model, and 31 latent variables were obtained. The Bayesian information criterion (BIC) score was -15 367.17. Based on professional knowledge, s6 common syndrome types were found, namely, syndrome of upward disturbance of wind-fire, Qi deficiency and blood stasis syndrome, syndrome of phlegm and blood stasis blocking collaterals, syndrome of phlegm-heat and fu-organ excess, syndrome of wind phlegm obstructing collaterals, and syndrome of stirring wind due to yin deficiency. In factor analysis, the symptoms with a frequency of >10% were selected, and 13 common factors were obtained and used for systematic cluster analysis. And 5 syndrome types were inferred: syndrome of wind phlegm obstructing collaterals, syndrome of phlegm-heat and fu-organ excess, Qi deficiency and blood stasis syndrome, syndrome of combined phlegm and blood stasis, and syndrome of yin deficiency and internal heat. According to the determination criteria of syndrome types in traditional Chinese medicine (TCM), 6 common syndrome types of cerebral infarction were finally determined. ConclusionAccording to the severity of the disease, the common syndromes of patients with cerebral infarction in rural areas of Eastern Henan were divided into the following categories: apoplexy involving channel and collateral: syndrome of upward disturbance of wind fire, syndrome of wind phlegm obstructing collaterals, and syndrome of stirring wind due to yin deficiency. Apoplexy involving zang and fu-viscera: syndrome of phlegm-heat and fu-organ excess, and syndrome of phlegm and blood stasis blocking collaterals. Recovery period: Qi deficiency and blood stasis syndrome. This study was basically consistent with the syndrome law in TCM theory, and provided reference for further establishing syndrome diagnostic criteria of cerebral infarction.

Objective: To evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI) with the novel Prizvalve® system in treating severe aortic stenosis. Methods: This is a single-center, prospective, single-arm, observational study. A total of 11 patients with severe aortic stenosis with high risk or inappropriate for conventional surgical aortic valve replacement (SAVR) were included, and TAVI was achieved with the Prizvalve® system between March 2021 and May 2021 in West China Hospital. Transthoracic echocardiography (TTE) was performed immediately after prosthesis implantation to evaluate mean transaortic gradient and maximal transaortic velocity. The device success rate was calculated, which was defined as (1) the device being delivered via the access, deployed, implanted and withdrawn, (2) mean transaortic gradient<20 mmHg (1 mmHg=0.133 kPa) or a maximal transaortic velocity<3 m/s post TAVI, and without severe aortic regurgitation or paravalvular leak post TAVI. TTE was performed at 30 days after the surgery, and all-cause mortality as well as the major cardiovascular adverse events (including acute myocardial infarction, disabling hemorrhagic or ischemic stroke) up to 30 days post TAVI were analyzed. Results: The age of 11 included patients were (78.1±6.3) years, with 8 males. A total of 10 patients were with NYHA functional class Ⅲ or Ⅳ. Devices were delivered via the access, deployed, implanted and withdrawn successfully in all patients. Post-implant mean transaortic gradient was (7.55±4.08) mmHg and maximal transaortic velocity was (1.78±0.44) m/s, and both decreased significantly as compared to baseline levels (both P<0.05). No severe aortic regurgitation or paravalvular leak was observed post TAVI. Device success was achieved in all the 11 patients. No patient died or experienced major cardiovascular adverse events up to 30 days post TAVI. Mean transaortic gradient was (9.45±5.07) mmHg and maximal transaortic velocity was (2.05±0.42) m/s at 30 days post TAVI, which were similar as the values measured immediately post TAVI (both P>0.05). Conclusions: TAVI with the Prizvalve® system is a feasible and relatively safe procedure for patients with severe aortic stenosis and at high risk or inappropriate for SAVR. Further clinical studies could be launched to obtain more clinical experience with Prizvalve® system.
