Objective:To investigate the diagnostic value of serum homocysteine(Hcy),soluble stromelysin 2(sST2)and cystatin C(CysC)for chronic heart failure(CHF).Methods:A total of 86 CHF patients admitted in our hospital were se-lected as CHF group,and 86 healthy individuals who underwent physical examination simultaneously were selected as healthy control group.Serum levels of Hcy,sST2 and CysC,plasma level of N terminal pro brain natriuretic peptide(NT-proBNP)and cardiac function indexes[left atrial diameter(LAD),left ventricular end diastolic diameter(LVEDd),left ventricular ejection fraction(LVEF)]were measured between two groups.Pearson correlation analysis was used to analyze the correlation among serum Hcy,sST2,CysC,plasma NT-proBNP and cardiac function indexes.Receiver operating characteristic curve(ROC)was drawn to evaluate the diagnostic value of serum Hcy,sST2 and CysC and their combined detection for CHF.Results:Compared with healthy control group,there were significant rise in scrum levels of Hcy,sST2 and CysC,plasma NT-proBNP level,LAD and LVEDd,and significant reduction in LVEF in CHF group,P=0.001 all.Pearson correlation analysis indicated that serum Hcy,sST2 and CysC levels were significant positively correlated with plas-ma NT-proBNP level,LAD and LVEDd(r=0.385～0.511,P＜0.05 or＜0.01),and significant inversely correlated with LVEF(r=-0.424～-0.402,P＜0.05 all).AUC of single detection of serum Hcy,sST2 and CysC diagnosing CHF was 0.624,0.720 and 0.870 respectively,and AUC of their combination was 0.865,which was significantly higher than any single detection,P＜0.05 or＜0.01.Conclusion:Serum levels of Hcy,sST2 and CysC abnormally increase in CHF patients,which can be used as auxiliary diagnostic indexes for CHF.The triple combined detection is of great signifi-cance for the diagnosis of CHF.

Objective Studies on the relationship between iodine,vitamin A(VA),and vitamin D(VD)and thyroid function are limited.This study aimed to analyze iodine and thyroid-stimulating hormone(TSH)status and their possible relationships with VA,VD,and other factors in postpartum women. Methods A total of 1,311 mothers(896 lactating and 415 non-lactating)from Hebei,Zhejiang,and Guangxi provinces were included in this study.The urinary iodine concentration(UIC),TSH,VA,and VD were measured. Results The median UIC of total and lactating participants were 142.00 μg/L and 139.95 μg/L,respectively.The median TSH,VA,and VD levels in all the participants were 1.89 mIU/L,0.44 μg/mL,and 24.04 ng/mL,respectively.No differences in the UIC were found between lactating and non-lactating mothers.UIC and TSH levels were significantly different among the three provinces.The rural UIC was higher than the urban UIC.Obese mothers had a higher UIC and a higher prevalence of excessive TSH.Higher UICs and TSHs levels were observed in both the VD deficiency and insufficiency groups than in the VD-sufficient group.After adjustment,no linear correlation was observed between UIC and VA/VD.No interaction was found between vitamins A/D and UIC on TSH levels. Conclusion The mothers in the present study had no iodine deficiency.Region,area type,BMI,and VD may be related to the iodine status or TSH levels.

Lung cancer is the leading cause of cancer-related deaths worldwide, especially non-small cell lung cancer (NSCLC). With the popularization of low-dose CT and the improvement of people’s awareness of physical examinations, the number of detected pulmonary nodules is gradually increasing, and there is a greater demand for standardized diagnostic and treatment guidelines. On April 23, 2024, the National Comprehensive Cancer Network updated its clinical practice guidelines for NSCLC to the version 5. Compared with the version 5 in 2023, the version 5 in 2024 updates focus on diagnostic evaluation, perioperative systemic therapy, treatment of advanced NSCLC, and molecular marker testing, which will be interpreted in this article with the aim of providing the latest guidance and reference for the diagnosis and treatment of lung cancer in China.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

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.

Chronic prostatitis is a process of kidney deficiency and blood stasis mixed with various pathological factors involving the essence chamber,which is manifested as kidney deficiency and blood stasis.Based on the concept of the"brain-heart-kidney-es-sence chamber"axis of medication,Xiongji Formula is applied to the treatment of chronic prostatitis,due to its"simultaneous holistic and local action"and effects of tonifying the kidney yang and assisting the systemic yang,acting on the brain,heart and kidney as a whole,and meanwhile activating blood circulation,eliminating blood stasis and restoring the function of the essence chamber.This pa-per discusses the etiology and pathogenesis of chronic prostatitis with kidney deficiency and blood stasis in Chinese medicine,expounds the significance of"brain-heart-kidney-essence chamber"axis of medication,and explores the specific value and clinical application of Xiongji Formula.

Objective To retrieve and extract the best evidence for preventing intracranial infections related to ex-ternal cerebrospinal fluid(CSF)drainage,and provide evidence-based support for reducing the incidence of intracra-nial infection caused by external CSF drainage.Methods Evidence-based care issues were determined according to PIPOST,and the best evidence on intracranial infection related to external CSF drainage tube was retrieved from top to bottom.The literature retrieval period was 2013-2023.Quality control of the literatures,as well as extraction and summary of the evidence were carried out by 2 trained graduate students.Results A total of 17 literatures were included in the analysis,including 3 guidelines,5 expert consensus,8 systematic reviews,and 1 randomized con-trolled trial.Management strategies from 3 dimensions(pre-catheterization,in-catheterization and post-catheteriza-tion)were obtained,including 20 pieces of evidence for preventing intracranial infection,such as preparation for ex-ternal CSF drainage tube,precautions during catheterization,and post-catheterization disposal.Conclusion There are differences in the management of external CSF drainage tube in clinical practice.It is necessary to develop uni-fied,standardized,and rational bundle strategies to prevent intracranial infection,so as to reduce the incidence of catheter-related intracranial infection.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
