Multi-stage automatic and rapid ablation and needle trajectory planning method for CT-guided percutaneous liver tumor ablation.

Background: Computer-assisted planning methods have increasingly contributed to preoperative ablation planning; however, these methods cannot automatically obtain the final optimal solution within a short time and are rarely validated in practice, greatly limiting their clinical applicability.

Purpose: We aimed to propose a full-automatic multi-stage ablation and needle trajectory planning method for CT-guided percutaneous liver ablation to attain the final optimal plans under multiple clinical constraints rapidly.

Methods: Our proposed method integrates the ablation zone planning fulfilling complete tumor coverage and critical structure avoidance while reaching a trade-off between ablation number and healthy tissue damage, and needle trajectory planning under multiple clinical constraints.

Shock Wave Therapy Alleviates Hypoxia/Reoxygenation-Induced Cardiomyocyte Injury by Inhibiting Both Apoptosis and Ferroptosis.

Shock wave therapy (SWT) is a new alternative therapy for patients with severe coronary artery disease that improves myocardial ischemic symptoms by delivering low-energy shock wave stimulation to ischaemic myocardium with low-energy pulsed waves. However, the specific mechanism of its protective effect is not fully understood, especially for the protective mechanism in cardiomyocytes after hypoxia/reoxygenation (H/R). We selected a rat H9c2 cardiomyocyte cell line to establish a stable H/R cardiomyocyte injury model by hypoxia/reoxygenation, and then used SWT for therapeutic intervention to explore its cardiomyocyte protective mechanisms.

Methods: 36 patients with PD and 7 patients with MSA were enrolled in this study. Three olfactory testing methods (SIT-12, Ch-SIT-12, and B-SITC) were used to test the olfactory function in all participants.

Tumor neoantigens and tumor immunotherapies.

As a high-risk group of patients with cancer, the elderly exhibit limited efficacy with traditional treatments. Immunotherapy emerges as a promising adjunctive therapeutic approach that holds potential in addressing the needs of geriatric patients with cancer. Neoantigens, a unique class of tumor-specific antigens generated by non-synonymous mutations, are garnering increasing attention as targets for immunotherapy in clinical applications.

[Differential expression of LLGL2 in prostate ductal adenocarcinoma and acinar adenocarcinoma and its significance].

To investigate the expression differences of LLGL2 between prostatic ductal adenocarcinoma (PDA) and prostatic acinar adenocarcinoma, and its potential clinical significance. Eighteen patients diagnosed of PDA or prostatic acinar adenocarcinoma with PDA component by histopathology during January 2015 and December 2019 in the Beijing Hospital, China were retrospectively studied. The transcriptome analysis was conducted using the tissue of PDA and prostatic acinar adenocarcinoma.

[Burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in China].

To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China.

Chinese expert consensus on prevention and control interventions for older adults with physical functional impairment (2022).

Older adults are at high risk for functional impairment, which is closely related to sarcopenia, falls, and frailty. This seriously affects their quality of life and health, and places a heavy burden on society and families. Although domestic and foreign sports recommendations and prevention and control guidelines/expert consensus have been issued for healthy older adults and functional impairment-related diseases, there is no guidance on prevention and control interventions for older adults with physical functional impairment.

Vitamin D3 and Lactobacillus rhamnosus GG/p40 Synergize to Protect Mice From Colitis by Promoting Vitamin D Receptor Expression and Epithelial Proliferation.

Background: While vitamin D (VitD) levels are negatively correlated with inflammatory bowel disease (IBD) activity, VitD supplementation does not reduce IBD severity. The probiotic Lactobacillus rhamnosus GG (LGG), which secretes p40, can upregulate colonic VitD receptor (VDR) expression. We therefore evaluated synergy between VitD3 and LGG/p40 in the treatment of mouse colitis.

Validation of a Metagenomic Next-Generation Sequencing Assay for Lower Respiratory Pathogen Detection.

Lower respiratory infection (LRI) is the most fatal communicable disease, with only a few pathogens identified. Metagenomic next-generation sequencing (mNGS), as an unbiased, hypothesis-free, and culture-independent method, theoretically enables the detection of all pathogens in a single test. In this study, we developed and validated a DNA-based mNGS method for the diagnosis of LRIs from bronchoalveolar lavage fluid (BALF).

[Diagnostic values of cyclin D1 immunocytochemistry and molecular testing in preoperative fine needle aspiration of undeterminate thyroid nodules].

To assess the value of cyclin D1 immunocytochemistry combined with a small panel molecular analysis in indeterminate cytological diagnosis of Bethesda category Ⅲ-Ⅴ. A consecutive cohort of 96 thyroid FNA specimens with indeterminate diagnosis (TBSRTC category Ⅲ-Ⅴ) and available histopathologic follow-up data were collected between December 2018 and December 2021 in Department of Pathology, Beijing Hospital. The cases were evaluated by cyclin D1 immunocytochemistry and molecular testing of BRAF or a small panel of markers (BRAF, N-RAS, H-RAS, K-RAS and TERT) in the FNA specimens.

[Global guidelines of colorectal cancer screening in high-risk population with family history of colorectal cancer: a systematic review].

To systematically summarize and evaluate the development of update and detailed recommendations of the existing global screening guidelines in high-risk population with a family history of colorectal cancer. The words "colorectal cancer", "screening", "guideline", "consensus", "recommendations" and "family history" in Chinese and English were used as MESH terms for literature retrieval, as well as entry terms. The retrieval was performed based on China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, PubMed, Embase, Cochrane Library and Web of Science, as well as official websites.

Multilaboratory assessment of metagenomic next-generation sequencing for unbiased microbe detection.

Introduction: Metagenomic next-generation sequencing (mNGS) assay for detecting infectious agents is now in the stage of being translated into clinical practice. With no approved approaches or guidelines available, laboratories adopt customized mNGS assays to detect clinical samples. However, the accuracy, reliability, and problems of these routinely implemented assays are not clear.

Method: Seventy-eight subjects with good nutrition were considered as the healthy control group. Twenty-eight male subjects who had malnutrition and were older than 70 years were included and randomly divided into the short-term (3 months) intervention group (n = 20) and the long-term (12 months) group (n = 8).

Expert consensus on the nursing management of critically ill elderly patients with coronavirus disease 2019.

The novel coronavirus (2019-nCoV) was first detected in patients with pneumonia of an unknown cause in Wuhan, China in December 2019. It has since been confirmed as the pathogen for the new coronavirus pneumonia, recently named "coronavirus disease 2019" (COVID-19) by the World Health Organization. Although the general population is commonly susceptible to the disease, infected elderly people show fast progression and severe manifestations with a high proportion in critical condition as a result of compromised immunity and underlying diseases.
