The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction （TIMI） risk score, which can be used to predict the prognosis and the need for revas-cularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance. Fragmented QRS （fQRS） has been shown to be a valuable electrocardiographic （ECG） index for predicting the prognosis of patients with coronary heart disease （Das et al., 2006, 2007）.展开更多

The aldehyde dehydrogenase 2(ALDH2) rs671 polymorphism has a prevalence of 30%–50% in Asian populations. In this study, we aimed to analyze risk factors contributing to the development of heart failure with preserved ejection fraction(HFpEF) along with the genetic exposure in Chinese patients hospitalized with cardiovascular diseases(CVD). Methods From July 2017 to October 2018, a total of 770 consecutive Chinese patients with normal left ventricular ejection fractions(LVEF) and established CVD(hypertension, coronary heart diseases, or diabetes) were enrolled in this prospective cross-sectional study. HFpEF was defined by the presence of at least one of symptom(dyspnoea and fatigue) or sign(rales and ankle swelling) related to heart failure;N-terminal pro-B-Type natriuretic peptide(NT pro-BNP ≥ 280 pg/mL);LVEF ≥ 50%;and at least one criterion related to elevated ventricular filling pressure or diastolic dysfunction(left atrial diameter > 40 mm, E/E’ ≥ 13, E’/A’ < 1 or concurrent atrial fibrillation). Logistic regression was performed to yield adjusted odds ratios(ORs) for HFp EF incidence associated with traditional and/or genetic exposures. Results Finally, among 770 patients with CVD, 92(11.9%) patients were classified into the HFpEF group according to the diagnostic criteria. The mean age of the participants was 67 ± 12 years, and 278(36.1%) patients were females. A total of 303(39.4%) patients were ALDH2*2 variant carriers. In the univariate analysis, eight exposures were found to be associated with HFpEF: atrial fibrillation, ALDH2*2 variants, hypertension, age, anaemia, smoking, alcohol consumption and sex. Multivariable logistic regression showed that 4 ‘A’ variables(atrial fibrillation, ALDH2*2 variants, age and anaemia) were significantly associated with an increased risk of HFpEF. Atrial fibrillation was associated with a 3.8-fold increased HFpEF risk(95% CI: 2.21–6.61, P < 0.001), and the other three exposures associated with increased HFpEF risk were the ALDH2*2 variant(OR = 2.41, 95% CI: 1.49–3.87, P < 0.001), age(OR = 2.14, 95% CI: 1.27–3.60, P = 0.004), and anaemia(OR = 1.79, 95% CI: 1.05–3.03, P = 0.032). These four variables predicted HFpEF incidence in Chinese CVD patients(C-statistic = 0.745, 95% CI: 0.691–0.800, P < 0.001). Conclusions 4 A traits(atrial fibrillation, ALDH2*2 variants, age and anaemia) were associated with an increased risk of HFpEF in Chinese CVD patients. Our results provide potential clues to the aetiology, pathophysiology and therapeutic targets of HFpEF.展开更多

Methods： 420 patients hospitalized in Peking University First Hospital, diagnosed with ASTEMI treated with emergency （PCI） from January 2001 to June 2011 were enrolled in this study. Estimated glomerular filtration rate （eGFR） was used as a measure of renal function. We compared the clinical parameters and outcomes between ASTEMI patients combined renal insufficiency and the patients with normal renal function. Results： There was a significant increase in the concentrations of fibrinogen and D-Dimer （P〈0.05） and a much higher morbidity of diabetes mellitus in the group of patients with chronic kidney disease （CKD; eGFR〈60 ml/（min-1.73 m^2）） （P〈0.01）. CKD （eGFR〈60 ml/（min.1.73 m^2）） was an independent predictor of in-hospital mortality for patients hospitalized with ASTEMI receiving PCI therapy rapidly （P=0.032, odds ratio （OR） 4.159, 95% confidence interval （CI） 1.127-15.346）. Conclusions： Renal insufficiency is an independent predictor of in-hospital mortality for patients hospitalized with ASTEMI treated with primary PCI.展开更多

We estimated the percentage of limb-girdle muscular dystrophy subtypes in Chinese people based on 68 patients with limb-girdle muscular dystrophy from the Myology Clinic, Neurology Department, First Hospital of Jilin University, China. A diagnosis of calpainopathy was made in 12 cases （17%）, and dysferlin deficiency in 10 cases （15%）. Two biopsies revealed α-sarcoglycan deficiency （3%）, and two others revealed a lack of caveolin-3 （3%）. A diagnosis of unclassified limb-girdle muscular dystrophy was made in the remaining patients （62%）. The ap-pearances of calpain 3- and dysferlin-deficient biopsies were similar, though rimmed vacuoles were unique to dysferlinopathy, while inflammatory infiltrates were present in both these limb-girdle muscular dystrophy type 2D biopsies. Macrophages were detected in seven dysferlinopathy biop-sies. The results of this study suggest that the distribution of limb-girdle muscular dystrophy sub-types in the Han Chinese population is similar to that reported in the West. The less necrotic, re-generating and inflammatory appearance of limb-girdle muscular dystrophy type 2A, but with more lobulated fibers, supports the idea that calpainopathy is a less active, but more chronic disease than dysferlinopathy. Unusual features indicated an extended limb-girdle muscular dystrophy disease spectrum. The use of acid phosphatase stain should be considered in suspected dysferlinopathies. To the best of our knowledge, this is the first report to define the relative proportions of the various forms of limb-girdle muscular dystrophy in China, based on protein testing.展开更多

Infants born after 34 weeks and before 37 weeks of gestation were enrolled from 25 hospitals in the Beijing area of China from October 2015 to October 2017. Data on enteral feeding practices were collected and analyzed. Results A total of 1,463 late preterm infants were enrolled, with a mean gestational age（GA） of 35.6（34.9, 36.1） weeks. The percentage of exclusive breastfeeding was 4.5% at the initiation of enteral feeding but increased to 14.4% at discharge. When human milk was not available, most infants（46.1%） were fed with preterm infant formula. The rate of exclusive human milk feeding in infants born at 34 weeks gestation was higher than at discharge（21.1% of infants born at 34 weeks＇ GA versus 12.1% of infants born at 35 weeks＇ GA versus 12.3% of infants born at 36 weeks＇ GA, P 〈 0.001）. Only 28.4% of late preterm infants achieved full enteral feeding at discharge, and only 19.2% achieved 120 kcal/（kg·d） by enteral feeding at discharge. Importantly, 40.5% of infants did not regain the birth weight at discharge. Conclusion Enteral feeding support of late preterm infants has not been standardized to achieve optimal growth. Moreover, the human milk feeding rate was low, and many late preterm infants did not achieve the goal of enteral feeding and failed to regain birth weight at the time of discharge. More aggressive enteral feedings protocols are needed to promote human milk feeding and optimize growth for late preterm infants.展开更多

We used routine screening data to determine the prevalence of HCV antibody in hospital patients, evaluate the epidemic trend of hepatitis C and formulate screening strategies.Methods Patient information and HCV antibody testing results were collected from January 2017 to December 2019 in 77 HCV sentinel hospitals in China. Univariate and multivariate logistic regression was used to determine the characteristics and associations.Results HCV antibody prevalence rates were distinct among patients in different departments, with a range of 0.33%–6.93%. Patients who were admitted to the liver disease-related departments(aOR =10.76;95% CI, 10.27–11.28), Internal Medicine(aOR = 2.87;95% CI, 2.75–3.00), and Department of Surgery(aOR = 1.95;95% CI, 1.87–2.04), were more likely to be tested for HCV antibody positive. HCV antibody prevalence was associated with patients aged 45 years and older(aOR = 2.74;95% CI,2.69–2.80), testing in infetious disease hospitals(aOR = 2.33;95% CI, 2.26–2.40) and secondary hospitals(aOR = 1.72;95% CI, 1.69–1.75). Patients in sentinel hospitals of the Northeast(aOR = 12.75;95% CI,12.40–13.11), the Central(aOR = 1.65;95% CI, 1.61–1.70), and the West(aOR = 1.78;95% CI, 1.73–1.83)China had higher HCV prevalence than those who were in the Eastern coastal area. Conclusion Those who were over 45 years old and saw doctors for liver diseases, and invasive diagnosis and treatment should be referred to HCV antibody testing.展开更多
BACKGROUND Metastases from pancreas or ampullary malignancies are common,but the spread to testicle and paratesticular tissue is exceedingly rare.To the best of our knowledge,fewer than 30 cases have been reported in ...BACKGROUND Metastases from pancreas or ampullary malignancies are common,but the spread to testicle and paratesticular tissue is exceedingly rare.To the best of our knowledge,fewer than 30 cases have been reported in the literature.More rarely,metastasis to tunica vaginalis testis occurs without involvement of the testes and epididymis.CASE SUMMARY A 65-year-old male who complained of painless swelling of the left scrotum for over 1 wk was referred to the Department of Urology.Scrotal ultrasound showed left testicular hydrocele with paratesticular masses.Chest computed tomography revealed lung metastasis and enlarged left supraclavicular lymph node.The blood tumor markersalpha-fetoprotein,human chorionic gonadotropin,and serum lactate dehydrogenase were withinnormal limits.The preoperative diagnosis was left testicular tumor with lung metastasis.Then radical orchidectomy of the left testicle and high ligation of the spermatic cord were performed,and postoperative histopathology suggested metastatic tumors that was confirmed by an abdominal computed tomographic scan.The positive computed tomography findings,in conjunction with the expression of cytokeratin 7(CK7),CK20,CK5/6,and absence of expression of Wilms’tumor suppressor gene 1,calretinin,melanocyte,prostate-specific antigen,thyroid transcription factor-1,GATA binding protein 3,caudal type homeobox 2,and napsinA supported the diagnosis of pancreatic adenocarcinoma.The outcome of this patient was unsatisfactory,and he died 3 mo later.CONCLUSION This case suggests that pancreatic metastatic carcinoma must be considered in the differential diagnosis of scrotal enlargement.The advanced age of the patient wassuggestive of a secondary testicular tumor.In addition,careful physical examination and ultrasonography as well as radiological examination have become a standard modality.展开更多

文摘BACKGROUND Microsatellite stable(MSS)metastatic colorectal cancer(mCRC)is characterized by an immunosuppressive tumor microenvironment,leading to limited efficacy of immunotherapy in these patients.Clinical trial data suggest that chemotherapy and anti-angiogenic therapy may have the potential to enhance the response to immunotherapy in these patients.However,whether these research findings can be“replicated”in clinical practice still requires further validation through real-world studies.This study aims to evaluate the effectiveness and safety of chemo-therapy combined with bevacizumab with or without anti-programmed death 1(PD-1)immunotherapy as the first-line regimen for MSS mCRC in the real world.AIM To evaluate the effectiveness and safety of chemotherapy combined with beva-cizumab with or without anti-PD-1 immunotherapy as the first-line regimen for MSS mCRC in the real world.METHODS We conducted a retrospective analysis of patients with MSS mCRC diagnosed at Peking University First Hospital and Jilin Cancer Hospital between January 2020 and December 2024.Patients were stratified into two treatment groups:(1)An experimental group receiving first-line chemotherapy combined with bevaci-zumab and anti-PD-1 immunotherapy;and(2)A control group receiving chemo-therapy plus bevacizumab alone.Propensity score matching was employed to balance baseline characteristics,including age,gender,Eastern Cooperative Onco-logy Group performance status,number of metastatic sites,and primary tumor location.The primary endpoints were progression-free survival and overall survival,while secondary endpoints included disease control rate,objective response rate,and treatment-related adverse events.Survival outcomes were assessed using Kaplan-Meier analysis with log-rank testing.Additionally,inverse probability of treatment weighting was applied for sensitivity analysis to validate the robustness of our findings.RESULTS The propensity score matching analysis identified 103 well-balanced patient pairs with a median follow-up of 25.5 months.The experimental group demonstrated numerically higher objective response(36.00%vs 23.08%,P=0.309)and disease control rates(96.00%vs 91.03%,P=0.6759)compared to the control group,though these differences were not statistically significant.Similarly,no significant survival benefit was observed for either progression-free survival[hazard ratio(HR)=0.7076,95%confidence interval(CI):0.4069-1.23,P=0.22]or overall survival(HR=1.154,95%CI:0.4712-2.827,P=0.75).Multivariate analysis identified liver metastases as an independent poor prognostic factor(HR=3.36,95%CI:1.71-6.60,P<0.001),while subgroup analyses revealed potential benefits of the experimental regimen in male patients(HR=0.33,95%CI:0.14-0.81,P=0.025)and those with right-sided primary tumors(HR=0.40,95%CI:0.17-0.95,P=0.022).Safety profiles were comparable between groups,though elevated lactate dehydrogenase emerged as an independent risk factor for poorer outcomes in the experimental group(HR=4.11,95%CI:1.02-16.55,P=0.046).CONCLUSION Chemotherapy combined with bevacizumab and anti-PD-1 immunotherapy could not demonstrate promising efficacy in treating MSS mCRC compared to the standard first-line chemotherapy regimen with bevacizumab.Male patients or those with right-sided mCRC may derive benefits from immune-based combination therapy.Further research is needed to investigate specific clinical characteristics or biomarkers to identify patients who may derive benefit from combined immunotherapy approaches.

文摘Effective treatment methods for stroke,a common cerebrovascular disease with a high mortality rate,are still being sought.Exosome therapy,a form of acellular therapy,has demonstrated promising efficacy in various diseases in animal models;however,there is currently insufficient evidence to guide the clinical application of exosome in patients with stroke.This article reviews the progress of exosome applications in stroke treatment.It aims to elucidate the significant potential value of exosomes in stroke therapy and provide a reference for their clinical translation.At present,many studies on exosome-based therapies for stroke are actively underway.Regarding preclinical research,exosomes,as bioactive substances with diverse sources,currently favor stem cells as their origin.Due to their high plasticity,exosomes can be effectively modified through various physical,chemical,and genetic engineering methods to enhance their efficacy.In animal models of stroke,exosome therapy can reduce neuroinflammatory responses,alleviate oxidative stress damage,and inhibit programmed cell death.Additionally,exosomes can promote angiogenesis,repair and regenerate damaged white matter fiber bundles,and facilitate the migration and differentiation of neural stem cells,aiding the repair process.We also summarize new directions for the application of exosomes,specifically the exosome intervention through the ventricular-meningeal lymphatic system.The review findings suggest that the treatment paradigm for stroke is poised for transformation.
文摘Radiofrequency ablation(RFA),particularly endoscopic ultrasound-guided RFA(EUS-RFA),has emerged as a promising minimally invasive approach for the treatment of pancreatic cancer,especially in patients with locally advanced or unresectable disease.This review outlines recent technological developments in EUS-RFA,including innovations in energy delivery systems,probe design,and real-time thermal monitoring,which have improved the precision and safety of the procedure.Clinical studies combining EUS-RFA with chemotherapy have demonstrated encouraging outcomes,with improvements in overall survival,progression-free survival,tumor necrosis,and symptom control compared to chemotherapy alone.Additionally,RFA-induced tumor antigen release and modulation of the tumor microenvironment suggest a potential synergistic role with immunotherapy.Despite its promise,the widespread adoption of EUS-RFA is limited by a lack of large-scale randomized controlled trials and standardized treatment protocols.

文摘Synapses are key structures involved in transmitting information in the nervous system,and their functions rely on the regulation of various lipids.Lipids play important roles in synapse formation,neurotransmitter release,and signal transmission,and dysregulation of lipid metabolism is closely associated with various neurodegenerative diseases.The complex roles of lipids in synaptic function and neurological diseases have recently garnered increasing attention,but their specific mechanisms remain to be fully understood.This review aims to explore how lipids regulate synaptic activity in the central nervous system,focusing on their roles in synapse formation,neurotransmitter release,and signal transmission.Additionally,it discusses the mechanisms by which glial cells modulate synaptic function through lipid regulation.This review shows that within the central nervous system,lipids are essential components of the cell membrane bilayer,playing critical roles in synaptic structure and function.They regulate presynaptic vesicular trafficking,postsynaptic signaling pathways,and glial-neuronal interactions.Cholesterol maintains membrane fluidity and promotes the formation of lipid rafts.Glycerophospholipids contribute to the structural integrity of synaptic membranes and are involved in the release of synaptic vesicles.Sphingolipids interact with synaptic receptors through various mechanisms to regulate their activity and are also involved in cellular processes such as inflammation and apoptosis.Fatty acids are vital for energy metabolism and the synthesis of signaling molecules.Abnormalities in lipid metabolism may lead to impairments in synaptic function,affecting information transmission between neurons and the overall health of the nervous system.Therapeutic strategies targeting lipid metabolism,particularly through cholesterol modulation,show promise for treating these conditions.In neurodegenerative diseases such as Alzheimer’s disease,Parkinson disease,and amyotrophic lateral sclerosis,dysregulation of lipid metabolism is closely linked to synaptic dysfunction.Therefore,lipids are not only key molecules in neural regeneration and synaptic repair but may also contribute to neurodegenerative pathology when metabolic dysregulation occurs.Further research is needed to elucidate the specific mechanisms linking lipid metabolism to synaptic dysfunction and to develop targeted lipid therapies for neurological diseases.

文摘Acute myocardial infarction （AMI） has a high mortality rate and poor prognosis for patients. The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction （TIMI） risk score, which can be used to predict the prognosis and the need for revas-cularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance. Fragmented QRS （fQRS） has been shown to be a valuable electrocardiographic （ECG） index for predicting the prognosis of patients with coronary heart disease （Das et al., 2006, 2007）.

文摘Background Endogenous aldehyde damages DNA and potentiates an ageing phenotype. The aldehyde dehydrogenase 2(ALDH2) rs671 polymorphism has a prevalence of 30%–50% in Asian populations. In this study, we aimed to analyze risk factors contributing to the development of heart failure with preserved ejection fraction(HFpEF) along with the genetic exposure in Chinese patients hospitalized with cardiovascular diseases(CVD). Methods From July 2017 to October 2018, a total of 770 consecutive Chinese patients with normal left ventricular ejection fractions(LVEF) and established CVD(hypertension, coronary heart diseases, or diabetes) were enrolled in this prospective cross-sectional study. HFpEF was defined by the presence of at least one of symptom(dyspnoea and fatigue) or sign(rales and ankle swelling) related to heart failure;N-terminal pro-B-Type natriuretic peptide(NT pro-BNP ≥ 280 pg/mL);LVEF ≥ 50%;and at least one criterion related to elevated ventricular filling pressure or diastolic dysfunction(left atrial diameter > 40 mm, E/E’ ≥ 13, E’/A’ < 1 or concurrent atrial fibrillation). Logistic regression was performed to yield adjusted odds ratios(ORs) for HFp EF incidence associated with traditional and/or genetic exposures. Results Finally, among 770 patients with CVD, 92(11.9%) patients were classified into the HFpEF group according to the diagnostic criteria. The mean age of the participants was 67 ± 12 years, and 278(36.1%) patients were females. A total of 303(39.4%) patients were ALDH2*2 variant carriers. In the univariate analysis, eight exposures were found to be associated with HFpEF: atrial fibrillation, ALDH2*2 variants, hypertension, age, anaemia, smoking, alcohol consumption and sex. Multivariable logistic regression showed that 4 ‘A’ variables(atrial fibrillation, ALDH2*2 variants, age and anaemia) were significantly associated with an increased risk of HFpEF. Atrial fibrillation was associated with a 3.8-fold increased HFpEF risk(95% CI: 2.21–6.61, P < 0.001), and the other three exposures associated with increased HFpEF risk were the ALDH2*2 variant(OR = 2.41, 95% CI: 1.49–3.87, P < 0.001), age(OR = 2.14, 95% CI: 1.27–3.60, P = 0.004), and anaemia(OR = 1.79, 95% CI: 1.05–3.03, P = 0.032). These four variables predicted HFpEF incidence in Chinese CVD patients(C-statistic = 0.745, 95% CI: 0.691–0.800, P < 0.001). Conclusions 4 A traits(atrial fibrillation, ALDH2*2 variants, age and anaemia) were associated with an increased risk of HFpEF in Chinese CVD patients. Our results provide potential clues to the aetiology, pathophysiology and therapeutic targets of HFpEF.
文摘Objective： To investigate the relationship between renal function and clinical outcomes among patients with acute ST-segment elevation myocardial infamtion （ASTEMI）, who were treated with emergency percutaneous coronary intervention （PCI）. Methods： 420 patients hospitalized in Peking University First Hospital, diagnosed with ASTEMI treated with emergency （PCI） from January 2001 to June 2011 were enrolled in this study. Estimated glomerular filtration rate （eGFR） was used as a measure of renal function. We compared the clinical parameters and outcomes between ASTEMI patients combined renal insufficiency and the patients with normal renal function. Results： There was a significant increase in the concentrations of fibrinogen and D-Dimer （P〈0.05） and a much higher morbidity of diabetes mellitus in the group of patients with chronic kidney disease （CKD; eGFR〈60 ml/（min-1.73 m^2）） （P〈0.01）. CKD （eGFR〈60 ml/（min.1.73 m^2）） was an independent predictor of in-hospital mortality for patients hospitalized with ASTEMI receiving PCI therapy rapidly （P=0.032, odds ratio （OR） 4.159, 95% confidence interval （CI） 1.127-15.346）. Conclusions： Renal insufficiency is an independent predictor of in-hospital mortality for patients hospitalized with ASTEMI treated with primary PCI.

文摘BACKGROUND Many studies have demonstrated the benefit of complete multivessel revascularization versus culprit-only intervention in patients of ST-segment elevation myocardial infarction(STEMI)and multivessel coronary artery disease.However,only a few single-center retrospective studies were performed on small Chinese cohorts.Our study aims to demonstrate the advantage of multivessel percutaneous intervention(PCI)strategy on 30-day in-hospital outcomes to patients with STEMI and multivessel disease in larger Chinese population.METHODS From the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome(CCC-ACS)project,5935 patients with STEMI and multivessel disease undergoing PCI and hospitalized for fewer than 30 days were analyzed.After 5:1 propensity score matching,3577 patients with culprit-only PCI and 877 with in-hospital multivessel PCI were included.The primary outcome was major adverse cardiovascular and cerebrovascular event(MACCE),defined as a composite of myocardial infarction,all-cause death,stent thrombosis,heart failure,and stroke.RESULTS Multivariable logistic regression analysis revealed that in-hospital multivessel PCI was associated with lower risk of 30-day MACCE(adjusted OR=0.75,95%CI:0.57-0.98,P=0.032)than culprit-only PCI and conferred no increased risk of allcause death,myocardial infarction,stent thrombosis,stroke,or bleeding.Subgroup analysis showed that MACCE reduction was observed more often from patients with trans-femoral access(OR=0.34,95%CI:0.15-0.74)than with trans-radial access(OR=0.87,95%CI:0.66-1.16,P for interaction=0.017).CONCLUSIONS The in-hospital multivessel PCI strategy was associated with a lower risk of 30-day MACCE than culprit-only PCI in patients with STEMI and multivessel coronary artery disease.
文摘BACKGROUND Obesity is associated with a better prognosis in patients with community-acquired pneumonia(the so-called obesity survival paradox),but conflicting results have been found.AIM To investigate the relationship between all-cause mortality and body mass index in patients with community-acquired pneumonia.METHODS This retrospective study included patients with community-acquired pneumonia hospitalized in the First Hospital of Qinhuangdao from June 2013 to November 2018.The patients were grouped as underweight(<18.5 kg/m^(2)),normal weight(18.5-23.9 kg/m^(2)),and overweight/obesity(≥24 kg/m^(2)).The primary outcome was all-cause hospital mortality.RESULTS Among 2327 patients,297(12.8%)were underweight,1013(43.5%)normal weight,and 1017(43.7%)overweight/obesity.The all-cause hospital mortality was 4.6%(106/2327).Mortality was lowest in the overweight/obesity group and highest in the underweight group(2.8%,vs 5.0%,vs 9.1%,P<0.001).All-cause mortality of overweight/obesity patients was lower than normal-weight patients[odds ratio(OR)=0.535,95%confidence interval(CI)=0.334-0.855,P=0.009],while the allcause mortality of underweight patients was higher than that of normal-weight patients(OR=1.886,95%CI:1.161-3.066,P=0.010).Multivariable analysis showed that abnormal neutrophil counts(OR=2.38,95%CI:1.55-3.65,P<0.001),abnormal albumin levels(OR=0.20,95%CI:0.06-0.72,P=0.014),high-risk Confusion-Urea-Respiration-Blood pressure-65 score(OR=2.89,95%CI:1.48-5.64,P=0.002),and intensive care unit admission(OR=3.11,95%CI:1.77-5.49,P<0.001)were independently associated with mortality.CONCLUSION All-cause mortality of normal-weight patients was higher than overweight/obesity patients,lower than that of underweight patients.Neutrophil counts,albumin levels,Confusion-Urea-Respiration-Blood pressure-65 score,and intensive care unit admission were independently associated with mortality in patients with community-acquired pneumonia.

文摘Objective This study aimed to evaluate the epidemiological,clinical and mycological characteristics of invasive candidiasis(IC)in China.Methods A ten-year retrospective study including 183 IC episodes was conducted in a tertiary hospital in Beijing,China.Results The overall incidence of IC from 2010–2019 was 0.261 episodes per 1,000 discharges.Candidemia(71.0%)was the major infective pattern;70.3%of the patients tested positive for Candida spp.colonization before IC and the median time to develop an invasive infection after colonization was13.5 days(interquartile range:4.5–37.0 days).Candida albicans(45.8%)was the most prevalent species,followed by Candida parapsilosis(19.5%),Candida glabrata(14.2%)and Candida tropicalis(13.7%).C.non-albicans IC was more common in patients with severe anemia(P=0.018),long-term hospitalization(P=0.015),hematologic malignancies(P=0.002),continuous administration of broad-spectrum antibiotics(P<0.001)and mechanical ventilation(P=0.012).In vitro resistance testing showed that11.0%of the Candida isolates were resistant/non-wild type(non-WT)to fluconazole,followed by voriconazole(9.6%),micafungin(3.8%),and caspofungin(2.9%).Fluconazole was the most commonly used drug to initiate antifungal therapy both before and after the proven diagnosis(52.6%and 54.6%,respectively).The 30-day and 90-day all-cause mortality rates were 24.5%and 32.7%,respectively.Conclusion The incidence of IC has declined in the recent five years.C.non-albicans contributed to more than half of the IC cases.Fluconazole can be used as first-line therapy if resistant strains are not prevalent.Prospective,multi-center surveillance of the clinical and mycological characteristics of IC is required.

文摘Traditional Chinese medicines(TCMs)are commonly used in China,and some of them have been proved to be effective against infection caused by certain pathogenic bacteria.In the present study,we aimed to describe the trends of antibacterial-effect traditional Chinese medicine(AeTCM)consumption and expenditure in secondary and tertiary hospitals in China using pharmaceutical sales data from January 2011 to December 2015.Aggregated monthly surveillance data on AeTCM sales in China’s hospitals were retrospectively analyzed.Population weighted daily define doses,which are the recommended daily amounts based on dosage regimen recommended in the manufacturers’instructions,were adopted.The AeTCM consumption was expressed in DDD per 1000 inhabitants per day(DID).The AeTCM expenditure was expressed in US dollars.A compound annual growth rate(CAGR)was used to describe the growth of AeTCM consumption and expenditure.A total of 1293 AeTCMs were matched and analyzed from 468 tertiary hospitals and 114 secondary hospitals from 28 provinces.The total AeTCM consumption and expenditure demonstrated a significant upward trend during the study period from 4.07 DID to 6.82 DID with a CAGR of 13.75%,and 839.75 million US dollars to 1276.82 million US dollars with a CAGR of 11.04%,respectively.Compared with eastern provinces,the consumption of AeTCMs was higher in the central and western provinces.Parenteral AeTCMs accounted for 7.20%of the total Ae TCM consumption,but nearly 45%of the total AeTCM expenditure.The AeTCM use in China demonstrated a rapid growth,which could be the result of the substitutional effect from antimicrobial stewardship and brought a potential risk of overuse.More studies are needed to further explore the potential efficacy of AeTCMs as an alternative approach towards infection treatment and to help confine antimicrobial resistance.
文摘Objective: This study aimed to evaluate Chinese tertiary hospital nurses' research output,research ability,and their related training needs regarding scientific research methodology and analyze the relations among them.Methods: A nationwide survey was conducted in China on a large sample of tertiary hospital nurses (n =27,335) recruited from 22 provinces,autonomous regions,and municipalities.A validated,self-designed questionnaire,consisted of a common questionnaire,the Science Research Skills Self-Rating Questionnaire (SRSQ) and the Scientific Research Training Needs Questionnaire (SRTNQ) were used to assess nurses' research output,self-rated research skills and research-training needs.Results: The nurses' scientific research participation rates (with 4.13%,7.85%,5.35%,and 2.04% in research projects,research attendance,papers published,and patent,respectively) and their self-rated research skills 25.00 (12.50,37.50) were very low.However,the research training needs were relatively high 53.12(37.50,75.00).Significant differences in research participation rates (research projects,research attendance,papers published,and patent),scientific research skills,and research-training needs were determined by age,highest education level,nursing experience,employment,technical title,administrative post,and clinical tutoring experience (P< 0.05).Female and male nurses had different research participation rates (only research projects and studies published) and scientific research skills (P < 0.05).Positive correlations were observed among research output,scientific research skills,and researchtraining needs (P < 0.01).Conclusions: Nurses' scientific research participation and self-rated research ability were below the optimal despite that they had relatively high research-training needs.Nurses should be provided further research training with tailored content to their characteristics and capacity.

文摘The relative frequencies of different subtypes of limb-girdle muscular dystrophies vary widely among different populations. We estimated the percentage of limb-girdle muscular dystrophy subtypes in Chinese people based on 68 patients with limb-girdle muscular dystrophy from the Myology Clinic, Neurology Department, First Hospital of Jilin University, China. A diagnosis of calpainopathy was made in 12 cases （17%）, and dysferlin deficiency in 10 cases （15%）. Two biopsies revealed α-sarcoglycan deficiency （3%）, and two others revealed a lack of caveolin-3 （3%）. A diagnosis of unclassified limb-girdle muscular dystrophy was made in the remaining patients （62%）. The ap-pearances of calpain 3- and dysferlin-deficient biopsies were similar, though rimmed vacuoles were unique to dysferlinopathy, while inflammatory infiltrates were present in both these limb-girdle muscular dystrophy type 2D biopsies. Macrophages were detected in seven dysferlinopathy biop-sies. The results of this study suggest that the distribution of limb-girdle muscular dystrophy sub-types in the Han Chinese population is similar to that reported in the West. The less necrotic, re-generating and inflammatory appearance of limb-girdle muscular dystrophy type 2A, but with more lobulated fibers, supports the idea that calpainopathy is a less active, but more chronic disease than dysferlinopathy. Unusual features indicated an extended limb-girdle muscular dystrophy disease spectrum. The use of acid phosphatase stain should be considered in suspected dysferlinopathies. To the best of our knowledge, this is the first report to define the relative proportions of the various forms of limb-girdle muscular dystrophy in China, based on protein testing.

文摘Objective To investigate the current enteral feeding practices in hospitalized late preterm infants in the Beijing area of China. Methods A multi-center, cross-sectional study was conducted. Infants born after 34 weeks and before 37 weeks of gestation were enrolled from 25 hospitals in the Beijing area of China from October 2015 to October 2017. Data on enteral feeding practices were collected and analyzed. Results A total of 1,463 late preterm infants were enrolled, with a mean gestational age（GA） of 35.6（34.9, 36.1） weeks. The percentage of exclusive breastfeeding was 4.5% at the initiation of enteral feeding but increased to 14.4% at discharge. When human milk was not available, most infants（46.1%） were fed with preterm infant formula. The rate of exclusive human milk feeding in infants born at 34 weeks gestation was higher than at discharge（21.1% of infants born at 34 weeks＇ GA versus 12.1% of infants born at 35 weeks＇ GA versus 12.3% of infants born at 36 weeks＇ GA, P 〈 0.001）. Only 28.4% of late preterm infants achieved full enteral feeding at discharge, and only 19.2% achieved 120 kcal/（kg·d） by enteral feeding at discharge. Importantly, 40.5% of infants did not regain the birth weight at discharge. Conclusion Enteral feeding support of late preterm infants has not been standardized to achieve optimal growth. Moreover, the human milk feeding rate was low, and many late preterm infants did not achieve the goal of enteral feeding and failed to regain birth weight at the time of discharge. More aggressive enteral feedings protocols are needed to promote human milk feeding and optimize growth for late preterm infants.
文摘Objective The prevalence and related factors of serum anti-HCV in different regions and hospitals have not been studied extensively in China. We used routine screening data to determine the prevalence of HCV antibody in hospital patients, evaluate the epidemic trend of hepatitis C and formulate screening strategies.Methods Patient information and HCV antibody testing results were collected from January 2017 to December 2019 in 77 HCV sentinel hospitals in China. Univariate and multivariate logistic regression was used to determine the characteristics and associations.Results HCV antibody prevalence rates were distinct among patients in different departments, with a range of 0.33%–6.93%. Patients who were admitted to the liver disease-related departments(aOR =10.76;95% CI, 10.27–11.28), Internal Medicine(aOR = 2.87;95% CI, 2.75–3.00), and Department of Surgery(aOR = 1.95;95% CI, 1.87–2.04), were more likely to be tested for HCV antibody positive. HCV antibody prevalence was associated with patients aged 45 years and older(aOR = 2.74;95% CI,2.69–2.80), testing in infetious disease hospitals(aOR = 2.33;95% CI, 2.26–2.40) and secondary hospitals(aOR = 1.72;95% CI, 1.69–1.75). Patients in sentinel hospitals of the Northeast(aOR = 12.75;95% CI,12.40–13.11), the Central(aOR = 1.65;95% CI, 1.61–1.70), and the West(aOR = 1.78;95% CI, 1.73–1.83)China had higher HCV prevalence than those who were in the Eastern coastal area. Conclusion Those who were over 45 years old and saw doctors for liver diseases, and invasive diagnosis and treatment should be referred to HCV antibody testing.

文摘BACKGROUND Metastases from pancreas or ampullary malignancies are common,but the spread to testicle and paratesticular tissue is exceedingly rare.To the best of our knowledge,fewer than 30 cases have been reported in the literature.More rarely,metastasis to tunica vaginalis testis occurs without involvement of the testes and epididymis.CASE SUMMARY A 65-year-old male who complained of painless swelling of the left scrotum for over 1 wk was referred to the Department of Urology.Scrotal ultrasound showed left testicular hydrocele with paratesticular masses.Chest computed tomography revealed lung metastasis and enlarged left supraclavicular lymph node.The blood tumor markersalpha-fetoprotein,human chorionic gonadotropin,and serum lactate dehydrogenase were withinnormal limits.The preoperative diagnosis was left testicular tumor with lung metastasis.Then radical orchidectomy of the left testicle and high ligation of the spermatic cord were performed,and postoperative histopathology suggested metastatic tumors that was confirmed by an abdominal computed tomographic scan.The positive computed tomography findings,in conjunction with the expression of cytokeratin 7(CK7),CK20,CK5/6,and absence of expression of Wilms’tumor suppressor gene 1,calretinin,melanocyte,prostate-specific antigen,thyroid transcription factor-1,GATA binding protein 3,caudal type homeobox 2,and napsinA supported the diagnosis of pancreatic adenocarcinoma.The outcome of this patient was unsatisfactory,and he died 3 mo later.CONCLUSION This case suggests that pancreatic metastatic carcinoma must be considered in the differential diagnosis of scrotal enlargement.The advanced age of the patient wassuggestive of a secondary testicular tumor.In addition,careful physical examination and ultrasonography as well as radiological examination have become a standard modality.
