Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective:To evaluate the clinical efficacy of single-wide-tunnel endoscopic submucosal dissection with single-clip-line traction (W-ESTD) for the treatment of early esophageal cancer and precancerous lesions with large area (≥ 3/4 circumference).Methods:A retrospective analysis was performed on patient data of large early esophageal cancer or precancerous lesions treated with digestive endoscopy at the Affiliated Huai'an NO.1 People's Hospital of Nanjing Medical University from January 2018 to January 2023. Patients were divided into W-ESTD group and endoscopic submucosal double-tunnel dissection (D-ESTD) group based on the technique used. Surgical speed, en bloc resection rate, R0 resection rate, curative resection rate, intraoperative and postoperative complications were compared between the two groups.Results:A total of 44 patients with large early esophageal cancer or precancerous lesions were included in this study, including 23 cases in the W-ESTD group and 21 cases in the D-ESTD group. There was no statistically significant difference in baseline data between the two groups ( P>0.05). The operating speeds of W-ESTD and D-ESTD groups were 29.97±11.89 mm2/min and 22.65±6.30 mm2/min, respectively, with significant difference ( t=2.580, P=0.014). There was no statistically significant difference between the two groups in terms of en bloc resection rate [95.7% (22/23) VS 100.0% (21/21), P=1.000], R0 resection rate [87.0% (20/23) VS 90.5% (19/21), P=1.000], or curative resection rate [73.9% (17/23) VS 85.7% (18/21), P=0.462]. No recurrence occurred. Intraoperative muscular injury occurred in 3 cases in the W-ESTD group and 5 cases in the D-ESTD group, and postoperative esophageal stricture occurred in 11 cases and 8 cases respectively, with no significant differences between the two groups ( P>0.05). Conclusion:Compared to D-ESTD, W-ESTD can significantly improve surgical speed and demonstrate itself as a safe and effective approach for treating large early esophageal cancer and precancerous lesions.

New threats posed by the emerging circulating variants of SARS-CoV-2 highlight the need to find conserved neutralizing epitopes for therapeutic antibodies and efficient vaccine design. Here, we identified a receptor-binding domain (RBD)-binding antibody, XG014, which potently neutralizes β-coronavirus lineage B (β-CoV-B), including SARS-CoV-2, its circulating variants, SARS-CoV and bat SARSr-CoV WIV1. Interestingly, antibody family members competing with XG014 binding show reduced levels of cross-reactivity and induce antibody-dependent SARS-CoV-2 spike (S) protein-mediated cell-cell fusion, suggesting a unique mode of recognition by XG014. Structural analyses reveal that XG014 recognizes a conserved epitope outside the ACE2 binding site and completely locks RBD in the non-functional "down" conformation, while its family member XG005 directly competes with ACE2 binding and position the RBD "up". Single administration of XG014 is effective in protection against and therapy of SARS-CoV-2 infection in vivo. Our findings suggest the potential to develop XG014 as pan-β-CoV-B therapeutics and the importance of the XG014 conserved antigenic epitope for designing broadly protective vaccines against β-CoV-B and newly emerging SARS-CoV-2 variants of concern.

Objective To systematic evaluate the curative effect of total hip arthroplasty (THA) through direct anterior approach versus (DAA) posterolateral approach (PSA).Methods All the randomized controlled trial (RCT) articles and observational research articles about the curative effect of THA through direct anterior approach (DAA group) versus posterolateral approach (PSA group)for treatment of hip disease that published at home and abroad included from database establishing to December 2017 were retrieved from Cochrane Library,Pubmed,Web of Science,CBM and China national knowledge internet (CNKI) through computer.The articles were screened and the information was extracted independently by two authors.A Meta-analysis was performed utilizing the RevMan 5.3 software.Results Two hundred and forty-nine articles were searched out in the initial stage.After screening,7 Chinese articles and 2 English articles (942 cases)were included in the final analysis,including 8 RCT articles and 1 observational research article,and 463 patients in direct anterior approach and 479 patients in posterolateral approach.The results of Meta-analysis demonstrated that the incision length,operation time,intraoperative blood less,Harris hip function scores at 1 month after surgery,visual analogue scale (VAS) scores at 24 hours after surgery,postoperative bed rest time and the hospital stay were better in DAA group compared to PSA group (SMD =-2.51,95％ CI:-4.84,-0.19,P=0.03);(SMD=0.84,95％ CI:0.10,1.59,P=0.03);(SMD=-1.52,95％ CI:-2.98,-0.05,P=0.04);(SMD=2.58,95％ CI:0.65,4.51,P=0.009);(SMD=-0.65,95％ CI:-0.91,-0.38,P＜0.01);(SMD=-1.85,95％ CI:-3.00,-0.70,P=0.002);(SMD =-1.12,95％ CI:-1.62,-0.61,P ＜0.01).There were no statistical difference in drainage (SMD =-1.45,95％ CI:-3.40,0.49,P =0.14),Harris hip function scores at last follow-up (SMD =0.91,95％ CI:-0.31,2.14,P =0.15),VAS scores at 48 hours after surgery (SMD =-1.21,95％ CI:-3.03,0.61,P =0.19),acetabular anteversion angles (SMD =-0.50,95％ CI:-1.06,0.05,P =0.07),acetabular abduction angles (SMD =-0.01,95％ CI:-0.32,0.30,P =0.97) and incidence of complications (OR =1.10,95％ CI:0.59,2.07,P =0.77) between the 2 groups.The result of analysis of publication bias according to Harris hip function scores at last follow-up and incidence of complications showed that the funnel-plot was essentially bilateral symmetry.Conclusions THA through DAA can significantly reduce the soft-tissue damage,and it is beneficial for patient's quick recovery,also it conforms to the current concept of minimally invasive treatment that worthy of promotion.

Objective:To analyze the value of maximum standardized uptake value (SUV max) of 18F-fluorodeoxyglucose (FDG) PET/CT in differentiating the malignant solitary pulmonary nodules (SPN) from benign ones. Methods:18F-FDG PET/CT imaging data of 84 patients (39 males, 45 females; age: 34-81(average: 61.1) years) with SPN in the First People′s Hospital of Lianyungang between September 2017 and June 2019 were retrospectively analyzed. The pathological results were taken as the gold standard. Differences of SUV max between benign and malignant SPN were analyzed with Mann-Whitney U test, and the best cut-off value for the diagnosis of benign and malignant SPN was measured by receiver operating characteristic (ROC) curve. The diagnostic efficacy was analyzed based on SUV max. Results:The pathological results confirmed 54 patients with malignant SPN, and 30 patients with benign SPN. SUV max of malignant group was significantly higher than that of benign group (5.48±4.08 vs 1.70(0.73, 3.33); U=443.50, P=0.001). The 84 SPN included 58 solid SPN and 26 subsolid SPN. SUV max of malignant subsolid SPN and benign ones were not significantly different ( U=56.00, P>0.05). The diagnostic value of SUV max in 58 cases of solid nodules were analyzed based on ROC curves, and the optimal cut-off value was 1.85. The corresponding diagnostic sensitivity, specificity, accuracy, negative predictive value and positive predictive value were 97.06%(33/34), 62.50%(15/24), 82.76%(48/58), 15/16, 78.57%(33/42), respectively. Conclusions:18F-FDG uptake of malignant SPN were higher than benign ones. The diagnosis of benign and malignant solid SPNs based on SUV max 1.85 has high sensitivity, negative predictive value and accuracy. SUV max has limited diagnostic value on subsolid SPN.
