Objective:To investigate the efficacy, feasibility, and safety of task-oriented exercise training for hospitalized elderly diabetic patients.Methods:This study is a parallel randomized controlled trial with a positive control and a single-blinded assessor.From July 2020 to July 2021, we included 84 elderly patients with type 2 diabetes who were hospitalized in the Department of Endocrinology at Beijing Hospital.These patients were randomly divided into two groups: the task-oriented exercise training group(TOE group)and the regular exercise training group(regular group). The TOE group participants were trained using a task-oriented exercise program that was specifically developed by our research team.On the other hand, the regular group participants were trained using a classical program that comprised of all exercise modes.Each subject received individualized exercise training for 10 consecutive days while staying in the hospital.We evaluated the efficacy, feasibility, and safety of the training programs by measuring the physical fitness of the participants, assessing the feasibility of the program, and monitoring any exercise-related adverse events that occurred.Results:A total of 79 subjects completed the entire intervention and follow-up period, with 40 subjects in the TOE group and 39 subjects in the regular group.In terms of efficacy, both groups showed improvement in their physical fitness indexes after the intervention, with no significant differences in the degree of improvement between the two groups(all P>0.05). When considering feasibility, the TOE group had a higher proportion of prospective feasibility at 87.5%(35 out of 40)compared to the regular group at 71.8%(28 out of 39). Similarly, the TOE group had a higher proportion of practical feasibility at 75.0%(30 out of 40)compared to the regular group at 53.8%(21 out of 39). The TOE group showed a significant advantage in practical feasibility between the two groups( χ2=3.862, P=0.049). As for safety, there were no exercise-related adverse events during the intervention in either group. Conclusions:The efficacy and safety of the task-oriented exercise program for hospitalized elderly diabetic patients is comparable to that of the regular program.Additionally, the task-oriented program is more feasible than the regular program.

Prostate cancer shows uneven distribution within the gland. The incidence rate in peripheral zones is higher than that in transition zone and central zone. Recently, prostate cancers in different zones have been found to have differences in clinical, pathological, molecular characteristics, and prognosis. However, the research method of spatial distribution still lacks standardization. In this paper, we will review the research progress on the spatial distribution of prostate cancer from the aspects of methodology, spatial distribution pattern, and clinical significance.

Objective To preliminarily investigate the anti-tumor effects of phytosphingosine(PHS)and the involvement of inducing apoptosis of leukemia cells.Methods Cellular model of leukemia was established in leukemia cell lines K562 and SUP-B15.CCK-8 assay and EdU assay were used to measure the viability and DNA synthesis of K562 and SUP-B15 cells.RNA-seq was carried out to verify the differentially expressed genes(DEGs)after PHS treatment.Gene Ontology(GO)enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were applied to analyze the involved functions and signaling pathways.Comparative Toxicogenomics Database(CTD)and Discovery Studio software were employed to predict the underlying targets of PHS and molecular docking.Cell apoptosis was detected by flow cytometry,mitochondrial membrane potential was evaluated by JC-1 probe,and protein expression of key molecules was validated by Western blotting.Results PHS inhibited the proliferation of K562 and SUP-B15 cells in a time-and dose-dependent manner.The half-maximal inhibitory concentration(IC50)of K562 cells was 17.67 and 12.52 pmol/L for 24 and 48 h,respectively,and the IC50 value of SUP-B15 cells was 17.58 and 14.86 μmol/L for 24 and 48 h,respectively.PHS treatment at a dose of 20 μmol/L for 48 h resulted in significant inhibition of DNA synthesis.GO enrichment analysis of the K562 cells showed that PHS might be involved in positive regulation of apoptotic process,plasma membrane and its integral components,and protein kinase binding and activity.Reverse predictive analysis showed that BCL-2 protein was the most likely target of PHS.PHS significantly increased the apoptotic rate of leukemia cells(P＜0.05)in a dose-dependent manner,reduced the mitochondrial membrane potential,and down-regulated BCL-2 level(P＜0.05)and up-regulated the levels of Cleaved caspase-3 and Cleaved caspase-9(P＜0.05).Conclusion PHS may inhibit the proliferation of leukemia cells by inducing mitochondria-dependent apoptosis,possibly through PHS and BCL-2 interaction.

Objective:Osteosarcoma is a highly aggressive primary malignant bone tumor commonly seen in children and adolescents,with a poor prognosis.Anchorage-dependent cell death(anoikis)has been proven to be indispensable in tumor metastasis,regulating the migration and adhesion of tumor cells at the primary site.However,as a type of programmed cell death,anoikis is rarely studied in osteosarcoma,especially in the tumor immune microenvironment.This study aims to clarify prognostic value of anoikis and tumor immune microenvironment-related gene in the treatment of osteosarcoma. Methods:Anoikis-related genes(ANRGs)were obtained from GeneCards.Clinical information and ANRGs expression profiles of osteosarcoma patients were sourced from the therapeutically applicable research to generate effective therapies and Gene Expression Omnibus(GEO)databases.ANRGs highly associated with tumor immune microenvironment were identified by the estimate package and the weighted gene coexpression network analysis(WGCNA)algorithm.Machine learning algorithms were performed to construct long-term survival predictive strategy,each sample was divided into high-risk and low-risk subgroups,which was further verified in the GEO cohort.Finally,based on single-cell RNA-seq from the GEO database,analysis was done on the function of signature genes in the osteosarcoma tumor microenvironment. Results:A total of 51 hub ANRGs closely associated with the tumor microenvironment were identified,from which 3 genes(MERTK,BNIP3,S100A8)were selected to construct the prognostic model.Significant differences in immune cell activation and immune-related signaling pathways were observed between the high-risk and low-risk groups based on tumor microenvironment analysis(all P<0.05).Additionally,characteristic genes within the osteosarcoma microenvironment were identified in regulation of intercellular crosstalk through the GAS6-MERTK signaling pathway. Conclusion:The prognostic model based on ANRGs and tumor microenvironment demonstrate good predictive power and provide more personalized treatment options for patients with osteosarcoma.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore whether indoor light-assisted therapy can rapidly improve depression and anxiety symptoms in patients with depression,as well as the safety of indoor-light-assisted therapy.Methods From September 2021 to December 2022,patients with depression were recruited from the Mental Health Center of the First Hospital of Hebei Medical University.According to the random number table method,patients were divided into test group and control group.The test group was treated with light therapy 30 minutes from 7:30 am to 8:00 am daily for 2 weeks in addition to antidepressant therapy.Antidepressant therapy was continued after completion of light therapy and patients were followed up for 2 weeks.The control group was treated with regular antidepressants throughout the four-week trial.Hamilton depression scale(HAMD17)and the Hamilton anxiety scale(HAMA)were used to assess the clinical symptoms at the baseline and the end of every week of treatment.Safety was evaluated using patient adverse events,anterior segment photography and visual testing.Results A total of 80 patients were enrolled,including 40 in the test group and 40 in the control group.The data of dropped were processed for missing values and then included in the statistical analysis.At the 1st(20.0％vs.0.0％)and 2nd(45.0％vs.17.5％)weekend of treatment,the response rate in the test group was significantly higher than that in the control group.There was an interaction between the time point and the group in HAMD17 total score(F=9.66,P<0.01).The scores of HAMD17 at the end of every week in the test group were significantly lower than that in the control group(P<0.05).There were significant differences in the reduction rate of total score in HAMD17[33.3％(25.0％,43.3％)vs.13.9％(9.9％,19.8％)]and HAMA[22.4％(16.5％,35.3％)vs.14.2％(4.4％,26.9％)]between the two groups(P<0.05).Incidences of adverse effect were not significantly different between the two groups(12.5％vs.10.0％,P=1.00).There were no severe adverse events or mania was reported in the test group and the eye examination showed no abnormality.Conclusion Compared with antidepressant therapy alone,indoor light therapy combined with antidepressant can quickly improve depression and anxiety symptoms in patients with depression,shorten the duration of depression treatment,and has good safety.

Breathing is of great significance in the monitoring of patients with obstructive sleep apnea hypopnea syndrome, perioperative monitoring and intensive care. In this study, a respiratory monitoring and verification system based on optical capacitance product pulse wave (PPG) is designed, which can synchronously collect human PPG signals. Through algorithm processing, the characteristic parameters of PPG signal are calculated, and the respiratory signal and respiratory frequency can be extracted in real time. In order to verify the accuracy of extracting respiratory signal and respiratory rate by the algorithm, the system adds the nasal airflow respiratory signal acquisition module to synchronously collect the nasal airflow respiratory signal as the standard signal for comparison and verification. Finally, the root mean square error between the respiratory rate extracted by the algorithm from the pulse wave and the standard respiratory rate is only 1.05 times/min.

Systemic lupus erythematosus (SLE) complicated with Aspergillus fumigatus brain abscess is rare and needs to be differentiated from bacterial brain abscess and neuropsychiatric lupus. This article reports 2 cases of surgically diagnosed SLE combined with Aspergillus fumigatus brain abscess. The first patient was a 34-year-old woman. Six months after the diagnosis of SLE, she developed convulsions and unconsciousness. She was diagnosed as neuropsychiatric lupus at the first hospitalization because of negative imaging. After discharge, repeated head magnetic resonance imaging revealed abscess-like signals. The second patient, a 20-year-old male, developed high fever, convulsions, and unconsciousness 3 years after the diagnosis of SLE, and head imaging showed an abscess-like signal. The etiology of the cerebrospinal fluid of the 2 patients was both negative, and the Aspergillus fumigatus brain abscess was diagnosed by pathology through abscess resection or drainage. After treatment with voriconazole, the symptoms were relieved and the lesions were subsided.

Objective:To investigate breast ultrasound imaging and pathological characteristics of patients with hereditary breast cancer-ovarian cancer syndrome (HBOC).Methods:A total of 12 patients with HBOC admitted to Shanxi Province Cancer Hospital from January 2012 to 2021 April were retrospectively analyzed. All patients were pathologically diagnosed as invasive breast cancer based on the preoperative puncture or surgical specimens, including 3 patients with double primary cancers of breast and ovary. The clinical, breast ultrasound imaging and pathological data of patients were analyzed.Results:The ultrasound imaging of HBOC usually showed regular morphology in 8 cases, clear border in 9 cases, no burr sign in 10 cases, no calcification in 10 cases, rear echo in 10 cases; the maximum blood flow velocity was (0.21±0.09) m/s, the vascular resistance index was 0.72±0.17, and aspect ratio ≤ 1 in 8 cases. Among 12 cases of HBOS, 9 cases were invasive ductal carcinoma, 3 cases were breast cancer with medullary features; histological grade: 7 cases of grade Ⅱ, 5 cases of grade Ⅲ; molecular classification: Luminal B type in 2 cases, human epithelial receptor 2 (HER2) type in 4 cases, and triple-negative type in 6 cases. The histological types of 3 patients with double primary cancers of breast and ovary were all high-grade serous carcinoma.Conclusions:HBOC is a type of neoplastic disease with a special genetic background. Ultrasound and pathological manifestations have certain characteristics. Sonographers should improve the understanding of the disease and pay attention to the medical history and family history in order to reduce the rate of misdiagnosis and increase the rate of diagnosis.
