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 re-evaluate systematic reviews on the application of virtual reality(VR)technology in limb rehabilitation for stroke patients,providing evidence to support the implementation of VR.Methods Systematic searches were conducted in Web of Science,PubMed,CINAHL,Cochrane Library,Embase,CNKI,CBM,WanFang,and VIP databases from their inception until March 2025,identifying systematic reviews/meta-analyses investigating VR for limb rehabilitation in stroke patients.2 researchers independently screened the literature.Methodological quality was evaluated using the Assessment of Mutiple System Reviews 2(AMSTAR 2)tool;reporting quality was evaluated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines;evidence quality was graded using the Grades of Recommendations Assessment,Development,and Evaluation(GRADE)system;literature overlap was assessed using the Corrected Covered Area(CCA)method.Results A total of 15 articles were included.According to AMSTAR 2,totally 3 reviews were of moderate quality,while the remainder were rated as low or very low quality.PRISMA scores ranged from 19.5 to 27.0 points.Based on GRADE,a review was classified as high quality,6 as moderate quality,and the remainder as low or very low quality.The CCA was 5.3％,indicating slight overlap.Conclusion VR contributes to the improvement of indicators such as upper limb motor function/mobility and lower limb balance in stroke patients.However,methodological limitations,including weak control of bias and inadequate handling of heterogeneity among included studies,restrict the overall quality of evidence.Further standardized,high-quality studies are needed to provide more reliable evidence to support clinical decision-making.

Objective:To analyze the characteristics of CD4 + T cell subsets and cytokines in patients with mixed connective tissue disease (MCTD) and the correlation of MCTD disease activity, laboratory data, and clinical symptoms with cytokines. Methods:A total of 48 MCTD patients (including 24 newly diagnosed patients and 24 treated patients) were enrolled from the Department of Rheumatology and Immunology, the Second Hospital of Shanxi Medical University from 2018 to 2021. Meanwhile, 49 healthy subjects who underwent physical examination were recruited (healthy control group). The absolute counts of CD4 + T cell subsets in peripheral blood samples were analyzed by flow cytometry. The levels of serum cytokines were detected by flow bead array. Analysis of variance and Mann-Whitney U test were used to compare the differences between groups. Pearson or Spearman correlation analysis was used for correlation analysis. Logistic regression analysis was used to analyze related factors. The receiver operating characteristic curve was used to detect the best cut-off value and effectiveness. Results:The absolute counts of Th1 ( P<0.01), Th2 ( P<0.01) and Treg cells ( P<0.01) in the newly diagnosed MCTD patients and the treated MCTD patients were lower than those in the healthy subjects. The levels of cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, IFN-γ, and TNF-α) in the two MCTD groups were higher than those in the healthy control group ( P<0.01). Further analysis revealed that the cardiac enzymes in MCTD patients included creatine kinase, creatine kinase-MB, aspartate aminotransferase, α-hydroxybutyrate dehydrogenase, and lactate dehydrogenase were positively correlated with cytokines ( P<0.05). In addition, it was found that IL-2 was positively correlated with erythrocyte sedimentation rate ( r=0.477, P<0.001), but it was negatively correlated with complement C3 ( r=-0.546, P=0.002) and complement C4 ( r=-0.422, P=0.02). IL-10 was correlated with the myositis symptoms in MCTD patients and the area under the receiver operator characteristic curve was 0.745 (95% CI: 0.576-0.915, P<0.05). Conclusions:This study provides insights into the unique immunological characteristics of CD4 + T lymphocyte subsets and cytokines in patients with MCTD, and also reveals a close correlation between cytokines and cardiac enzymes in MCTD patients. IL-2 has been shown to be associated with disease activity in MCTD patients. The level of IL-10 may be related to the occurrence of myositis symptoms in MCTD.

Objective:To explore and screen the immunophenotypic characteristics of acute promyelocytic leukemia (APL) by multiparameter flow cytometry (MFC).Methods:A retrospective and descriptive study. A total of 130 acute myeloid leukemia (AML) patients who registrated in Hebei Yanda Lu Daopei Hospital were studied, among which there were 44 classical APL (cAPL), 24 microgranular variant of APL (APLv) and 62 non-APL patients (including NPM1 mut AML and AML with KMT2A rearrangement). MFC immunotyping was used to analyze and compare the median expression intensity (MEI) of side scatter (SSC), along with the ratio of the MEI on leukemic cells with those on lymphocytes (T/L MEIR), the median fluorescence intensity (MDFI) of CD34, myeloperoxidase (MPO), CD64 and CD9 on leukemic cells, as well as the ratios of these MDFIs on leukemic cells with those on lymphocytes (T/L MDFIR). Receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic efficiency of the multiparameters model for distinguishing cAPL and non-APL, APLv and non-APL. Results:The MEI and T/L MEIR of SSC in the cAPL group were higher than those in the APLv and non-APL groups ( P<0.05), and these two parameters in APLv group were higher than those in the non-APL group, respectively ( P<0.05). The MDFIs of CD34 in cAPL and APLv groups were higher than those in the non-APL group ( P<0.05), and the T/L MDFIR of CD34 was higher in APLv group than non-APL group ( P<0.05). The MDFIs of MPO and CD9, as well as the T/L MDFIRs in cAPL and APLv groups were both higher than those in the non-APL group, respectively ( P<0.05). The MDFI and T/L MDFIR of CD64 in the cAPL group were higher than those in non-APL group, respectively ( P<0.05). ROC curve results showed that the area under the curve (AUC) of MEI of SSC, the MDFI of CD64 and CD9, as well as the T/L MEIR of SSC and T/L MDFIR of CD9 were 0.932, 0.816, 0.893, 0.960 and 0.894 for diagnosing cAPL, respectively, and the AUC of these parameters were 0.725, 0.737, 0.791, 0.729 and 0.736 for diagnosis APLv, respectively ( P<0.05). Conclusion:MFC method can analyze and screen the immunophenotypic characteristics of APL for differential diagnosis of cAPL, APLv and non-APL patients.

Objective To investigate the application effect of a bedside ultrasound-guided intestinal cleaning program in patients with severe acute pancreatitis.Methods A total of 51 patients with severe acute pancreatitis admitted to the ICU of a tertiary A hospital in Shandong from March to September 2023 were selected by convenience sampling method,and they were divided into an experimental group and a control group according to random number table method.The experimental group was given the bedside ultrasound-guided intestinal cleaning program,and the control group was given the routine intestinal cleaning program.Acute gastrointestinal injury ultrasonography score,the incidence of grade Ⅲ acute gastrointestinal injury and intra-abdominal pressure were compared between the 2 groups before intervention,on the 3rd and 5th day.Results There was an interaction effect between time and group in the comparison of acute gastrointestinal injury ultrasonography scores in the 2 groups(F=7.478,P<0.001);simple effect analysis showed that acute gastrointestinal injury ultrasonography scores in the experimental group were lower than those in control group on the 3rd and 5th day,with statistically significant differences(P<0.05).The incidence of grade Ⅲ acute gastrointestinal injury in the experimental group(23%)was lower than that in the control group(60%),with statistically significant differences(P<0.05).The intra-abdominal pressure had an interaction effect between the 2 groups(F=47.128,P<0.001);simple effect analysis showed that the intra-abdominal pressure in the experimental group was lower than that in the control group on the 3rd and 5th day,with statistically significant differences(P<0.05).Conclusion The bedside ultrasound-guided intestinal cleaning program can improve acute gastrointestinal injury and reduce intra-abdominal hypertension in patients with severe acute pancreatitis.
