ObjectiveTo explore the clinical characteristics and risk factors for 30-day mortality in hospitalized patients with bloodstream infections (BSI) caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). MethodsData were obtained retrospectively from the electronic medical records of inpatients at a tertiary A-grade hospital in Shanghai from January 2016 to December 2023. The collected variables included age, gender, department, surgical treatment, empirical antibiotic therapy, Pitt Bacteremia score (PBS), Charlson comorbidity index (CCI), INCREMENT-CPE score (ICS), length of hospital stay, the time from CRKP-BSI to discharge and, etc. The follow-up period ended upon discharge, with the follow-up outcomes defined as in-hospital mortality or discharge. The endpoint was defined as death within 30 days (including day 30) caused by CRKP-BSI or infection-related complications. Patients who survived within 30 days after CRKP-BSI were classified into the survival group, while those who died within 30 days were classified into the death group. Independent risk factors for 30-day mortality in patients with CRKP-BSI were analyzed using univariate and multivariate Cox regression analysis. ResultsA total of 71 hospitalized patients with CRKP-BSI, comprising 51 males and 20 females, with an average age of (65.12±18.25) years, were included during the study period. The M (P₂₅, P₇₅) of hospital stay were 37.00 (24.00, 56.00) days, and M (P₂₅, P₇₅) of the duration from CRKP-BSI to discharge or death were 18.00 (7.00, 35.00) days. There were 20 deaths (28.17%) in the death group and 51 survivors (71.83%) in the survival group. The results of multivariate Cox regression analysis showed that the ICS as an independent risk factor for 30-day mortality in CRKP-BSI patients (HR=1.379, 95%CI: 1.137‒1.671, P=0.001). Each 1-point increase in the ICS was associated with a 37.9% increase in the risk of mortality. ConclusionThe ICS is found to be a risk factor for 30-day mortality in patients with CRKP-BSI, which may facilitate the prediction for the risk of 30-day mortality and thereby support clinical decision-making for patients with CRKP-BSI.

OBJECTIVE: To analyze the rules of moxibustion for low back pain by ZHOU Meisheng by using data mining and knowledge graph technology. METHODS: Taking the medical cases of moxibustion for low back pain from ZHOU Meisheng's legacy manuscripts and existing works as the research objects, information on disease types, symptoms, tongue manifestations, pulse conditions, syndrome patterns, moxibustion methods and acupoints were collected. Frequency statistics and community analysis were conducted by the ancient and modern medical record cloud platform V 2.3.7, cluster analysis of high-frequency acupoints was performed by SPSS26.0, association rule analysis of high-frequency acupoints was performed by SPSS Modeler 18.0, and the generated linked data were imported into Cytoscape 3.9.1 for complex network analysis. Knowledge graph of moxibustion for low back pain by ZHOU Meisheng was constructed based on the results of data mining. The data storage and display of knowledge graph were realized through the Neo4j 3.5.25 graph database, and the Cypher query language was used for knowledge graph retrieval and discovery. RESULTS: A total of 219 medical cases were collected, involving 14 disease types, 85 related clinical symptoms, 5 related TCM syndrome types, and 6 moxibustion methods. The acupoints were mostly attributed to the governor vessel, the bladder meridian of foot-taiyang, non-meridian and non-acupoint areas. The core prescription of acupoints derived from complex network analysis included tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34), which were largely coincides with high-frequency acupoints. Cluster analysis obtained 4 cluster combinations. Community analysis yielded 6 communities, each corresponding to different acupoints.The constructed knowledge graph contained 187 nodes and 696 relationships, by retrieving clinical elements related to low back pain, the disease-moxibustion association graph, disease-acupoint association graph, accompanying symptom-acupoint association graph and syndrome type-matching point association graph were obtained. CONCLUSION When treating low back pain with moxibustion, ZHOU Meisheng adopts the principle of promoting circulation, distinguishing diseases to determine the treatment, selecting acupoints according to the diseases, and matching points according to the symptoms.And taking tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34) as core acupoints, combined with tenderness point selection, acupoint selection based on meridian and zangfu syndrome differentiation, "sunshine area" acupoint selection, yin-yang acupoint matching. Additionally, he skillfully employs special points, such as Zhongzhu (KI15) and ear tips, pays attention to the reform of moxibustion tools, and innovates the moxibustion techniques, using distinctive moxibustion tools and methods to treat low back pain.

Obstructive sleep apnea (OSA) is a common sleep disordered breathing disorder. As a major global public health problem, untreated OSA can lead to a variety of adverse health outcomes, including various cardiovascular and cerebrovascular diseases, metabolic disorders, and psychiatric disorders such as anxiety and depression. Traditional OSA therapies such as positive airway pressure (PAP), weight loss, oral appliance, upper airway surgery, and postural therapy focus on the anatomical factors of OSA. However, the pathogenesis of OSA is heterogeneous, and non-anatomical factors also play an important role in most patients. Although there is no drug with exact efficacy for the treatment of OSA, with the deepening understanding of the pathophysiological mechanism of OSA, more and more clinical studies are devoted to the study of drug treatment of OSA and its complications, and a series of results have been achieved. The following is a review of the relevant studies on drug treatment of OSA in recent years, hoping to provide literature support and theoretical basis for future research on drug treatment of OSA.

Mesenchymal stem cells(MSCs)are self-regenerating,rapidly proliferating pluripotent stem cells that depend primarily on their derived pro-angiogenic,inflammatory regulatory,and tro-phic factors to exert beneficial effects that attenu-ate deleterious inflammatory responses,reduce vascular damage,and promote tissue repair and re-generation.Obstructive sleep apnea hypoventila-tion syndrome(OSAHS)is a chronic disorder marked by oropharyngeal collapse during sleep,re-sulting in transient reduced airflow,large fluctua-tions in intrathoracic pressure,and intermittent hy-poxia and hypercapnia.OSAHS subsequently cyto-kine-mediated inflammatory cascades,oxidative stress,and ischemia,recruit MSCs from inflamed and damaged tissues through MSCs-derived of anti-inflammatory and pro-angiogenic factor activity,re-duce hypoxia,suppress inflammation,promote re-generation,and prevent fibrosis in OSAHS-injured tissues.In this paper,we will describe the patho-genesis of inflammation,oxidative stress,fibrosis and ischemia from the perspective of OSAHS,high-lighting the current research progress on MSCs-de-pendent regulation of OSAHS-related pathology.

Chronic obstructive pulmonary disease (COPD), a respiratory disease characterized by inflammation due to neutrophil infiltration, has become the third leading cause of death worldwide. After the occurrence of COPD, the persistent accumulation of neutrophils can promote the excessive formation of neutrophil extracellular traps (NETs), which plays an important role in local capture and clearance of pathogens, rapid control of infection, and immune regulation. This article mainly introduces the mechanism of COPD occurrence and NETs formation as well as the research progress of NETs in COPD, and summarizes the relevant drug targets for COPD treatment based on NETs, aiming to provide a reference for further research.

Ischemic stroke, a cerebrovascular disease with high incidence, high mortality, high disability rate and high recurrence rate, is an important cause of death and disability of middle-aged and elderly people in China, and imposes a huge burden to society and families. Therefore, it is essential to identify the risk factors associated with ischemic stroke and effectively prevent them. Studies have shown that obstructive sleep apnea is an independent risk factor for ischemic stroke. However, the exact pathological mechanism of their association has not been clarified. With the development of next-generation sequencing technology, more and more studies have focused on intestinal microbiota. They have found that obstructive sleep apnea can cause intestinal microbiota changes, and intestinal microbiota may be closely related to ischemic stroke. Therefore, this paper attempts to investigate the relationship between intestinal flora and ischemic stroke, so as to reveal the potential pathological mechanism of ischemic stroke caused by obstructive sleep apnea.

Objective To investigate the effect and mechanism of colchicine on mouse liver cancer via Hippo sig-naling pathway.Methods The 6-week-old male C57BL/6J mice were randomly divided into 3 groups:diethylni-trosamine(DEN)/carbon tetrachloride(CCl4)/ethanol(C2H5OH)induced mouse liver cancer model and col-chicine(0.1 mg/kg)intervention were established in control group,model group and colchicine group.From week 1st to week 2nd,the model group and the colchicine group were intraperitoneally injected with 1.0％DEN once a week.From week 3rd to week 7th,20％CCl4 dissolved in olive oil solution(5 ml/kg)was intragastric ad-ministration twice a week.From week 8th to week 18th,20％CC14 dissolved in olive oil solution(6 ml/kg)was intragastric twice a week.The colchicine group was given continuous intragastric administration for 20 weeks.The control group was given the corresponding solvent.Liver index,alanine aminotransferase(ALT)and aspartate ami-notransferase(AST)serum biochemical indexes were detected.Western blot and immunofluorescence were used to detect the expression levels of MST1,pYAP,YAP,pTAZ and TAZ proteins in liver tissues of mice in each group.Results The liver surface of mice in the control group was smooth and soft,while the liver of mice in the model group was rough and hard with granular nodules.The above lesions were significantly improved in the colchicine group.HE staining showed that the liver lobular structure of mice in the control group was normal,while the liver lobular structure of mice in the model group was disordered,with a small amount of fat droplets,extensive tissue necrosis,inflammatory cell infiltration,and fat vacuoles.The degree of liver lesions of mice after colchicine inter-vention was significantly reduced.The results of immunofluorescence and Western blot showed that compared with the control group,the protein expression levels of pYAP and pTAZ in liver tissue of model group mice were signifi-cantly decreased,while the protein expression levels of MST1,YAP and TAZ increased.After colchicine interven-tion,the protein expression levels of MST1,pYAP and pTAZ were significantly up-regulated,while the protein ex-pression levels of YAP and TAZ were down-regulated.Conclusion The therapeutic effect of colchicine on mouse liver cancer may be related to its activated Hippo signaling pathway.

Objective To explore the experience and causes of self-neglect of elderly diabetic patients in community,so as to provide references for community nursing workers to identify and intervene the self-neglect behavior of elderly diabetic patients.Methods An interpretative phenomenological method was used to collect data from elderly diabetic patients registered in 3 community health service centers in Hangzhou,Zhejiang Province through semi-structured interviews.Van Manen's method was used to analyze qualitative data.Results The experience and reasons of self-neglect of elderly diabetic patients in community were summarized into 4 themes and 10 sub-themes,including neglecting personal health(low sense of self-worth,high level of self-esteem,being afraid of compromising the family),neglecting blood glucose management(weak health awareness,difficulty in blood glucose management),inadequate self-care capacity(poor financial situation,insufficient personal time,diminished mobility)and inadequate perceived support(low social support,insufficient emotional support).Conclusion The experience and reasons of self-neglect of elderly diabetic patients in community are diversified.Community health services and nursing workers should pay attention to the performance of self-neglect behavior of elderly diabetic patients and actively explore effective prevention and intervention measures.
