Objective:To explore the therapeutic effect of traditional Chinese medicine emotional nursing combined with Baduanjin in rehabilitation nursing of patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods:This randomized controlled study enrolled 84 CHD patients undergoing PCI admitted in the First Hospital of Hunan University of Chinese Medicine between June 2022 and June 2023.Patients were ran-domly divided into control group(n=42)and intervention group(n=42).Patients in the control group received routine nursing,while those in the intervention group received additional traditional Chinese medicine emotional nursing combined with Baduanjin exercise.Both groups were continuously intervened for 8 weeks.Anxiety and de-pression,cardiac function and quality of life were compared between two groups.Results:After 8-week interven-tion,compared to patients in the control group,those in the intervention group had significant higher left ventricu-lar ejection fraction(LVEF)[(55.18±5.60)％vs.(50.34±5.28)％],6min walking distance(6MWD)[(321.27±19.92)m vs.(281.81±18.39)m],dimensional scores of physical limitation[(75.64±5.11)points vs.(65.14±4.32)points],anginal stability[(88.52±7.06)points vs.(73.66±7.28)points],anginal frequency[(82.79±6.20)points vs.(72.90±7.79)points],treatment satisfaction[(88.55±5.61)points vs.(73.80±7.51)points]and disease perception[(60.98±3.64)points vs.(50.30±5.60)points]of Seattle angina questionnaire(SAQ)(P＜0.001 all),and significant lower scores of self-rating anxiety scale(SAS)[(42.98±4.98)points vs.(47.95±4.49)points],self-rating depression scale(SDS)[(39.76±5.54)points vs.(43.98±5.28)points],left ventricu-lar end-diastolic diameter(LVEDd)[(48.07±4.74)mm vs.(51.71±4.31)mm]and left ventricular end-sys-tolic diameter(LVESd)[(45.20±4.31)mm vs.(49.52±4.55)mm](P＜0.001 all).Conclusion:Traditional Chinese medicine emotional nursing combined Baduanjin may relieve negative emotions,improve heart function and quality of life in patients with coronary heart disease after PCI.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

OBJECTIVE: Pneumoconiosis, a lung disease caused by irreversible fibrosis, represents a significant public health burden. This study investigates the causal relationships between gut microbiota, gene methylation, gene expression, protein levels, and pneumoconiosis using a multi-omics approach and Mendelian randomization (MR). METHODS: We analyzed gut microbiota data from MiBioGen and Esteban et al. to assess their potential causal effects on pneumoconiosis subtypes (asbestosis, silicosis, and inorganic pneumoconiosis) using conventional and summary-data-based MR (SMR). Gene methylation and expression data from Genotype-Tissue Expression and eQTLGen, along with protein level data from deCODE and UK Biobank Pharma Proteomics Project, were examined in relation to pneumoconiosis data from FinnGen. To validate our findings, we assessed self-measured gut flora from a pneumoconiosis cohort and performed fine mapping, drug prediction, molecular docking, and Phenome-Wide Association Studies to explore relevant phenotypes of key genes. RESULTS: Three core gut microorganisms were identified: Romboutsia ( OR = 0.249) as a protective factor against silicosis, Pasteurellaceae ( OR = 3.207) and Haemophilus parainfluenzae ( OR = 2.343) as risk factors for inorganic pneumoconiosis. Additionally, mapping and quantitative trait loci analyses revealed that the genes VIM, STX8, and MIF were significantly associated with pneumoconiosis risk. CONCLUSIONS This multi-omics study highlights the associations between gut microbiota and key genes ( VIM, STX8, MIF) with pneumoconiosis, offering insights into potential therapeutic targets and personalized treatment strategies.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

Objective:To investigate the completion rate of tumor evaluation at initial assessment and after neoadjuvant therapy for mid and low rectal cancer patients in the national multicenter real-world database.Methods:The prospective real-world study was conducted. The clinicopathological data of 1 074 patients who underwent surgical treatment for mid and low rectal cancer in 47 national medical institutions, including Peking Union Medical College Hospital et al, from May 12,2023 to May 11,2024 were collected. Observation indicators: (1) clinical characteristics of patients with mid and low rectal cancer; (2) initial colonoscopy and pathologic evaluation of tumors in patients with mid and low rectal cancer; (3) initial imaging evaluation of patients with mid and low rectal cancer; (4) imaging evaluation after neoadjuvant therapy for patients with mid and low rectal cancer. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3). Count data were described as absoluter numbers and/or percentages. Results:(1) Clinical characteristics of patients with mid and low rectal cancer. Of the 1 074 patients, there were 713 males and 361 females, aged 63(56,70)years. The body mass index of 1 074 patients was 24(21,26)kg/m 2.For American Society of Anesthesiologists classification, there were 147 cases of stage Ⅰ, 641 cases of stage Ⅱ, 157 cases of stage Ⅲ, 2 cases of stage Ⅳ, and there were 127 cases missing data. (2) Initial colonoscopy and pathologic evaluation of tumors in patients with mid and low rectal cancer. Of the 1 074 patients, there were 787 cases (73.28%) undergoing complete colonoscopy, and there were only 197 cases (18.34%) undergoing immunohistochemical evaluation of all four mismatch repair proteins. (3) Initial imaging evaluation of patients with mid and low rectal cancer. Of the 1 074 patients, there were 842(78.40%) patients completing magnetic resonance imaging (MRI) or ultrasound evaluation, and there were 914(85.10%) patients completing chest, abdomen, and pelvis enhanced computed tomography (CT) evaluation. In the 149 patients completing rectal ultrasound evaluation, there were 122 cases (81.88%) comple-ting T staging evaluation, and there were 81 cases (54.36%) completing N staging evaluation. In the 808 patients completing rectal MRI evaluation, there were 708 cases (87.62%) completing T staging evaluation, and there were 590 cases (73.02%) completing N staging evaluation. (4) Imaging evalua-tion after neoadjuvant therapy for patients with mid and low rectal cancer. Of the 388 patients with neoadjuvant therapy, there were 332 patients (85.57%) completing MRI or ultrasound evaluation, and there were 327 patients (84.28%) completing chest, abdomen, and pelvis enhanced CT evalua-tion. In the 70 patients completing rectal ultrasound evaluation, there were 65 cases (92.86%) com-pleting T staging evaluation, and there were 49 cases (70.00%) completing N staging evaluation. In the 327 patients completing rectal MRI evaluation, there were 246 cases (75.23%) completing T staging, and there were 228 cases (69.72%) completing N staging evaluation. Conclusion:The com-pletion rate of tumor imaging evaluation at initial assessment and after neoadjuvant therapy for mid and low rectal cancer patients on a national scale is relatively good.

BACKGROUND:Inflammation and apoptosis play key roles in the pathological process of cervical spondylotic myelopathy.Previous studies have shown that Pueraria lobata decoction has favorable therapeutic effects on cervical spondylotic myelopathy.OBJECTIVE:To investigate the effects and mechanism of Pueraria lobata decoction in neuroinflammatory response and apoptosis in rats with cervical spondylotic myelopathy.METHODS:Sixty Sprague-Dawley rats were randomly divided into six groups:a normal group,a sham-operated group,a model group,and three groups that received low,medium,and high doses of Pueraria lobata decoction.An animal model of cervical spondylotic myelopathy was constructed through compression of the spinal cord with water-absorbing and expanding material.Gastric administration of Pueraria lobata decoction(4.86,9.72,and 19.44 g/kg)was given in the three Pueraria lobata decoction groups 2 weeks after surgery,and the resting groups were given saline by gavage,once daily for 4 weeks.Motor function evaluation(Basso-Beattie-Bresnahan score)was performed in rats on days 1,7,14,21 and 28 after drug administration.At 4 weeks after drug administration,hematoxylin-eosin staining was used to observe the pathomorphologic changes in spinal cord tissue;immunofluorescence double staining was used for the detection of microglial cell polarization in spinal cord tissue;quantitative fluorescence PCR was used to detect the changes in the expression of interleukin-6 and interleukin-1β mRNA;western blot assay was used to detect the protein expression of p-NF-κB p65,NF-κB p65,NLRP3,ASC,Cleaved Caspase-1,Bax,Bcl-2,Cleaved Caspase-3,NOX4,p-Drp1,Drp1,and Mfn2 in spinal cord tissues;TUNEL assay was used to detect apoptosis in spinal cord tissues;and DHE staining was used to detect reactive oxygen species levels in rat spinal cord tissues.RESULTS AND CONCLUSION:(1)Compared with the normal and sham-operated groups,reduced Basso-Beattie-Bresnahan scores were observed in the model group(P<0.05),spinal cord neurons were crumpled and malformed with vacuolike changes.The Basso-Beattie-Bresnahan scores in the low-,medium-and high-dose Pueraria lobata decoction groups were significantly higher than those in the model group(P<0.05),and spinal cord neuronal damage reduced significantly.(2)Compared with the normal and sham-operated groups,there were elevated levels of Iba-1 and inducible nitric oxide synthase proteins and increased interleukin-6 and interluekin-1β mRNA expression in the spinal cord tissue of rats in the model group(P<0.05).The expression levels of Iba-1,inducible nitric oxide synthase,p-NF-κB,NLRP3,ASC and cleaved caspase-1 proteins as well as interleukin-6 and interleukin-1β mRNAs in the spinal cord tissues of rats in the low-,medium-and high-dose Pueraria lobata decoction groups were reduced compared with those in the model group(P<0.05).(3)Compared with the normal and sham-operated groups,the rate of TUNEL-positive cells and the levels of Bax and cleaved caspase-3 proteins were increased in the spinal cord tissues of rats in the model group(P<0.05),while the expression of Bcl-2 protein was reduced(P<0.05).Compared with the model group,the above indexes were significantly improved in the low-,medium-and high-dose Pueraria lobata decoction groups.(4)Compared with the normal and sham-operated groups,the model group exhibited increased levels of reactive oxygen species,along with elevated expression of NOX4 and p-Drp1 proteins(P<0.05)and reduced expression of Mfn2 protein(P<0.05)in the rat spinal crod tissue.Compared with the model group,the low-,medium-,and high-dose Pueraria lobata decoction groups exhibited reduced levels of reactive oxygen species,as well as decreased expression of NOX4 and p-Drp1 proteins(P<0.05)and increased expression of Mfn2 protein(P<0.05)in the rat spinal cord tissue.To conclude,Pueraria lobata decoction inhibits neuroinflammatory responses and neuronal apoptosis in the rat model of cervical spondylotic myelopathy,and the mechanism of action may be related to the regulation of the NOX4/reactive oxygen species/DRP1 signaling pathway.

Objective:To explore the therapeutic effect of traditional Chinese medicine emotional nursing combined with Baduanjin in rehabilitation nursing of patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods:This randomized controlled study enrolled 84 CHD patients undergoing PCI admitted in the First Hospital of Hunan University of Chinese Medicine between June 2022 and June 2023.Patients were ran-domly divided into control group(n=42)and intervention group(n=42).Patients in the control group received routine nursing,while those in the intervention group received additional traditional Chinese medicine emotional nursing combined with Baduanjin exercise.Both groups were continuously intervened for 8 weeks.Anxiety and de-pression,cardiac function and quality of life were compared between two groups.Results:After 8-week interven-tion,compared to patients in the control group,those in the intervention group had significant higher left ventricu-lar ejection fraction(LVEF)[(55.18±5.60)％vs.(50.34±5.28)％],6min walking distance(6MWD)[(321.27±19.92)m vs.(281.81±18.39)m],dimensional scores of physical limitation[(75.64±5.11)points vs.(65.14±4.32)points],anginal stability[(88.52±7.06)points vs.(73.66±7.28)points],anginal frequency[(82.79±6.20)points vs.(72.90±7.79)points],treatment satisfaction[(88.55±5.61)points vs.(73.80±7.51)points]and disease perception[(60.98±3.64)points vs.(50.30±5.60)points]of Seattle angina questionnaire(SAQ)(P＜0.001 all),and significant lower scores of self-rating anxiety scale(SAS)[(42.98±4.98)points vs.(47.95±4.49)points],self-rating depression scale(SDS)[(39.76±5.54)points vs.(43.98±5.28)points],left ventricu-lar end-diastolic diameter(LVEDd)[(48.07±4.74)mm vs.(51.71±4.31)mm]and left ventricular end-sys-tolic diameter(LVESd)[(45.20±4.31)mm vs.(49.52±4.55)mm](P＜0.001 all).Conclusion:Traditional Chinese medicine emotional nursing combined Baduanjin may relieve negative emotions,improve heart function and quality of life in patients with coronary heart disease after PCI.

Objective To summarize the clinical features,treatment and prognosis of patients with primary central nervous system lymphoma(PCNSL)with clonal bone marrow B cells,and to explore the influence on clinical diagnosis and treatment.Methods PCNSL patients with clonal bone marrow B cells diagnosed by flow cytometry between Jan 2020 and Jul 2023 at Huashan Hospital of Fudan University were enrolled.The auxiliary examination data of these patients were collected,including complete blood count,routine biochemistry,bone marrow aspiration and biopsy,contrast-enhanced brain MRI,and whole-body PET-CT.Kaplan-Meier was used to draw the survival curve,and relevant literature was reviewed.Results A total of 223 newly diagnosed PCNSL patients were included,187 of whom completed bone marrow puncture and biopsy evaluation.We found clonal bone marrow B cells in 16 of 187 cases(8.56%)by flow cytometry.2 patients showed B lymphoma involving the bone marrow.All patients received a high-dose methotrexate based chemotherapy.The median progression free survival(PFS)of 16 patients with clonal bone marrow B cells was 11.1 months,and the median PFS of 171 patients with normal bone marrow was 12.6 months.There was no significant difference in the PFS between the two groups.Conclusion PCNSL with clonal bone marrow B cells had no specific clinical features,but bone marrow flow cytometry showed clonal B cells.High-dose methotrexate treatment regimen is effective.There was no significant difference in PFS for PCNSL patients with clonal B cells and normal findings in bone marrow.Clonal B cells in bone marrow may be caused by monoclonal B-cell lymphocytosis(MBL),lymphoma involves the bone marrow and the presence of common precursor cells.Bone marrow examination should be performed in the initial evaluation of suspected PCNSL.
