Objective To systematically evaluate the methodological quality and the measurement attributes of the assessment tools for risk of falls perception in the elderly,therefore to provide evidence-based references for medical staff to select a proper assessment tool.Methods Literature on studies of the assessment tools for risk of falls perception in the elderly was retrieved across databases and websites including Medline,Embase,PubMed,Web of Science,CINAHL,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP and China Biology Medicine(CBM).The retrieval period was from the inception of the databases to 1st June,2024.Two researchers independently screened the retrieved literature and extracted the data.The bias risk list and quality standards of the consensus-based standards for the selection of health measurement instruments(COSMIN)were used to systematically evaluate the attributes of the assessment tools.Results A total of 22 studies were included,covering 21 scales for the risk of falls perception in the elderly.All the scales had certain risks of bias,and none of them reported cross-cultural validity/measurement equivalence and measurement error.The fall risk questionnaire(FRQ)was rated as Class C recommendation due to the high-quality evidences indicated its"inadequate"internal consistency and responsiveness.The remaining scales were rated as Class B recommendation due to their uncertainty in content validity.Conclusion In comparison with the assessment tools for risk of falls perception in the elderly,the self-awareness of falls in elderly scale(SAFE,a primary choice)and the fall risk perception scale for the elderly in community(FRPSE,the secondary choice)are recommended for their comprehensive structure of measurement and relatively complete evaluation of measurement.However,further studies are required to validate the clinical applicability and measurement attributes of the SAFE and FRPSE.

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.

Objective To investigate the predictive value of dynamic monitoring of transcutaneous oxygen partial pressure [p_tc(O₂)], transcutaneous carbon dioxide partial pressure [p_tc(CO₂)], serum amyloid A (SAA), and interleukin-6 (IL-6) levels in predicting bronchopulmonary dysplasia (BPD) in neonates with neonatal respiratory distress syndrome (NRDS). Methods A total of 240 NRDS patients were selected as the research subjects and divided into BPD group (108 cases) and non-BPD group (132 cases) based on whether BPD occurred. The levels of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 were compared between the two groups on the 1st, 7th, and 14th day after birth. Spearman correlation analysis was used to explore the correlation between each indicator and the degree of illness. The relative risk (RR) and 95% confidence interval (CI) were used to evaluate the impact of each indicator on BPD in NRDS patients. Receiver operating characteristic (ROC) curves and decision curve analysis were used to evaluate the predictive efficacy and clinical net benefit of each indicator for BPD. Results On the 1st day after birth, there were no statistically significant differences in p_tc(O₂), p_tc(CO₂), serum SAA, and IL-6 levels between the two groups (P>0.05). On the 7th and 14th day after birth, the p_tc(O₂) in the BPD group was lower than that in the non-BPD group, while the p_tc(CO₂) and serum SAA, IL-6 levels were higher than those in the non-BPD group (P < 0.05). Correlation analysis results showed that the degree of BPD in children was negatively correlated with p_tc(O₂) on the 7th day after birth (r=-0.724, P < 0.05), and positively correlated with p_tc(CO₂), SAA, and IL-6 on the 7th day after birth (r=0.635, 0.830, 0.715, P < 0.05). The degree of pulmonary dysfunction in children was negatively correlated with p_tc(O₂) on the 7th day after birth (r=-0.719, P < 0.05), and positively correlated with p_tc(CO₂), SAA, and IL-6 on the 7th day after birth (r=0.673, 0.756, 0.696, P < 0.05). On the 7th day after birth, the p_tc(O₂) of BPD patients was negatively correlated with SAA and IL-6 (r=-0.605, -0.623, P < 0.05), while p_tc(CO₂) was positively correlated with SAA and IL-6 (r=0.618, 0.650, P < 0.05). ROC curve showed that the combined prediction of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 on the 7th day after birth for NRDS complicated with BPD was better than the individual prediction of the four indicators, with an area under the curve of 0.938 (95%CI, 0.899 to 0.965). The risk of BPD in high-expression of p_tc(CO₂), SAA, and IL-6 was 2.256, 1.668, and 1.667 times higher than that in low-expression, respectively. The risk of BPD in high-expression of p_tc(O₂) was 0.568 times higher than that in low-expression. The decision curve analysis showed that when the threshold value was within the range of 0.2 to 0.9, the combined model of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 was superior to the individual prediction in predicting the net benefit rate of BPD in NRDS patients on the 7th day after birth. Conclusion The severity of NRDS complicated with BPD is closely related to p_tc(O₂), p_tc(CO₂), SAA, and IL-6, and the combined detection of the four indicators can help improve the predictive efficacy and net benefit rate of NRDS complicated with BPD.

Diabetic cardiomyopathy(DCM)is a metabolic disease and a leading cause of heart failure among people with diabetes.Mass spectrometry imaging(MSI)is a versatile technique capable of combining the molecular specificity of mass spectrometry(MS)with the spatial information of imaging.In this study,we used MSI to visualize metabolites in the rat heart with high spatial resolution and sensitivity.We optimized the air flow-assisted desorption electrospray ionization(AFADESI)-MSI platform to detect a wide range of metabolites,and then used matrix-assisted laser desorption ionization(MALDI)-MSI for increasing metabolic coverage and improving localization resolution.AFADESI-MSI detected 214 and 149 metabolites in positive and negative analyses of rat heart sections,respectively,while MALDI-MSI detected 61 metabolites in negative analysis.Our study revealed the heterogenous metabolic profile of the heart in a DCM model,with over 105 region-specific changes in the levels of a wide range of metabolite classes,including carbohydrates,amino acids,nucleotides,and their derivatives,fatty acids,glycerol phospholipids,carnitines,and metal ions.The repeated oral administration of ferulic acid during 20 weeks significantly improved most of the metabolic disorders in the DCM model.Our findings provide novel insights into the molecular mechanisms underlying DCM and the potential of ferulic acid as a therapeutic agent for treating this condition.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance， Innovation， and Development of traditional Chinese medicine（TCM） and the spirit of the National Conference on TCM， Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis （AR） and they reached a basic consensus. In recent years， the prevalence of AR has been on the rise， threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity， and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease， western medicine features rapid onset. However， it is cost-intensive and causes severe surgical trauma， and the recurrence is common. TCM boasts diverse methods for AR， which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion， runny nose， or dysosmia in the attack stage， preventing recurrence in the remission stage， and treating refractory AR or steroid-resistant AR. In particular， acupuncture enjoys a reputation in treatment of AR， which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR， TCM regulates the psychosomatic conditions， which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine， give full play to the unique nonnegligible and irreplaceable advantages of TCM， formulate a comprehensive diagnosis and treatment scheme for learning and promotion， and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.

Objective:To explore the value of radiographic assessment of lung edema (RALE) score in evaluating the severity and prognosis of patients with acute respiratory distress syndrome (ARDS).Methods:A retrospective study was conducted. Patients with ARDS admitted to the department of intensive care unit (ICU) of Affiliated Nantong Third Hospital of Nantong University from January 2016 to November 2020 were enrolled. Clinical data of those patients were collected, and two senior radiologists who did not know the outcome of the patients independently scored each chest radiograph, the mean value of which was taken as the RALE score. The patients were divided into death group and survival group according to the 28-day prognosis. The differences of the basic data, PaO 2/FiO 2, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and RALE score between groups were analyzed. ARDS patients were classified according to the Berlin standard and RALE scores were compared between groups. Then, the correlations between RALE score and PaO 2/FiO 2, SOFA score, APACHEⅡ score were analyzed. The prognostic capacity of RALE score for 28-day prognosis of ARDS patients were analyzed by Kaplan-Meier survival curve. Results:Of the 98 ARDS patients, 62 were included in the final analysis, 39 patients survived and 23 patients died. The 28-day mortality was 37.1%. Compared with the survival group, patients in the death group were older (years old: 72.83±12.21 vs. 64.44±14.68), had lower PaO 2/FiO 2 [mmHg (1 mmHg = 0.133 kPa): 122.66±48.32 vs. 150.26±50.40], and higher SOFA score and greater difference of RALE score between the third day and the first day after admission (D3-D1 RALE score) (SOFA score: 11.26±3.91 vs. 9.04±3.72, D3-D1 RALE score: 1.35±6.42 vs. -2.74±7.35), with statistically significant differences (all P < 0.05). However, there were no significant differences in gender, cause of ARDS, APACHEⅡ score, and RALE scores on the first and the third day of admission (D1 RALE, D3 RALE) between the two groups. Among the 62 patients, there were 11 mild cases (17.7%), 36 moderate cases (58.1%), and 15 severe cases (24.2%). The D1 RALE score of patients with mild and moderate ARDS were lower than those of patients with severe ARDS (19.09±3.65, 22.58±6.79 vs. 27.07±5.23, both P < 0.05). Correlation analysis showed that D1 RALE score was negatively correlated with PaO 2/FiO 2 ( r = -0.385, P = 0.002), and positively correlated with SOFA score and APACHEⅡ score ( r1 = 0.433, r2 = 0.442, both P < 0.001). Kaplan-Meier survival curve analysis showed that the 28-day survival rate of ARDS patients in D3-D1 RALE score ≥ -1 group was significantly higher than that in D3-D1 RALE score < -1 group (73.08% vs. 55.56%; log-rank test: χ 2 = 3.979, P = 0.046). Conclusions:The RALE score is a simple and reliable non-invasive evaluation index, which can be used to evaluate the severity of ARDS patients. The difference of RALE score in early stage is helpful to identify ARDS patients with poor prognosis.

Detailed knowledge on tissue-specific metabolic reprogramming in diabetic nephropathy (DN) is vital for more accurate understanding the molecular pathological signature and developing novel therapeutic strategies. In the present study, a spatial-resolved metabolomics approach based on air flow-assisted desorption electrospray ionization (AFADESI) and matrix-assisted laser desorption ionization (MALDI) integrated mass spectrometry imaging (MSI) was proposed to investigate tissue-specific metabolic alterations in the kidneys of high-fat diet-fed and streptozotocin (STZ)-treated DN rats and the therapeutic effect of astragaloside IV, a potential anti-diabetic drug, against DN. As a result, a wide range of functional metabolites including sugars, amino acids, nucleotides and their derivatives, fatty acids, phospholipids, sphingolipids, glycerides, carnitine and its derivatives, vitamins, peptides, and metal ions associated with DN were identified and their unique distribution patterns in the rat kidney were visualized with high chemical specificity and high spatial resolution. These region-specific metabolic disturbances were ameliorated by repeated oral administration of astragaloside IV (100 mg/kg) for 12 weeks. This study provided more comprehensive and detailed information about the tissue-specific metabolic reprogramming and molecular pathological signature in the kidney of diabetic rats. These findings highlighted the promising potential of AFADESI and MALDI integrated MSI based metabolomics approach for application in metabolic kidney diseases.

Objective:To investigate the risk factors of citrate accumulation in patients with liver failure treated with regional citrate anticoagulated continuous renal replacement therapy (RCA-CRRT).Methods:The clinical data of liver failure patients with RCA-CRRT admitted to department of intensive care unit (ICU) of Nantong Third People's Hospital from January 2017 to June 2020 were retrospectively analyzed. The selected patients were divided into citrate accumulation group and control group according to whether there was citrate accumulation (serum total calcium/free calcium ratio ≥ 2.4) during CRRT. The age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), mean arterial pressure (MAP), norepinephrine (NE) dose, blood lactic acid (Lac) concentration, liver function status, citrate dose, filter time and prognosis of the patients were compared between the two groups. Unconditional Logistic regression was used to analyze the risk factors for citrate accumulation.Results:Among 48 patients with RCA-CRRT and liver failure, 20 patients had citrate accumulation (accumulation group), and a total of 96 CRRTs were performed; the remaining 28 patients did not have citrate accumulation (control group), a total of 106 CRRTs were performed. There were no significant differences in age and APACHEⅡ score between the two groups. Compared with the control group, the MAP in the accumulation group was lower [mmHg (1 mmHg = 0.133 kPa): 66.9±13.6 vs. 86.4±8.3, P = 0.032], and the dosage of NE (μg/min: 16.3±8.4 vs. 5.9±2.8, P = 0.015) and lactic acid level (mmol/L: 4.89±1.45 vs. 2.98±0.87, P = 0.004) were higher, the damage of liver function was more serious [total bilirubin (TBil, μmol/L): 220.4±45.2 vs. 163.4±43.8, P = 0.012; Child-Pugh score: 12.0±2.5 vs. 8.8±1.4, P = 0.029; model for end-stage liver disease (MELD) score: 31.30±8.22 vs. 21.78±6.40, P = 0.041], hourly citric acid dosage (mmol/h: 27.4±6.9 vs. 19.3±4.9, P = 0.032) and total citric acid dosage (mmol: 3 393±809 vs. 1 819±502, P = 0.039) were higher. Although there were no significant differences in the length of ICU stay, total length of hospitalization stay and cost of hospitalization between the two groups, the 28-day mortality of the accumulation group was higher than that of the control group (60.0% vs. 28.6%, P = 0.039). Unconditional Logistic regression analysis showed that MAP [odds ratio ( OR) = 2.901, 95% confidence interval (95% CI) was 0.921-19.493, P = 0.019], NE dosage ( OR = 2.098, 95% CI was 1.923-12.342, P = 0.002), Lac level ( OR = 5.201, 95% CI was 3.211-9.433, P = 0.012), Child-Pugh score ( OR = 1.843, 95% CI was 0.437-7.420, P = 0.018), MELD score ( OR = 3.012, 95% CI was 0.384-12.843, P = 0.031), hourly citric acid dosage ( OR = 4.254, 95% CI was 1.734-11.839, P = 0.011) and total citric acid dosage ( OR = 4.109, 95% CI was 1.283-18.343, P = 0.001) were risk factors for citrate accumulation. Conclusion:In patients with tissue hypoperfusion and severe liver function damage, citrate anticoagulation should be avoided or the dosage of citric acid should be reduced, in order to avoid citrate accumulation.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China. Unfortunately, most of HCC patients were diagnosed at the intermediate or advanced stage, losing the chance to receive the surgical intervention. Locoregional interventional treatment is one of the major therapeutic options for inoperable HCC treatment and prolongs the survival of the patients. Evaluation of the efficacy of the treatment is the important to determine the further therapy strategies. Currently, the evaluation of patients’ response is mainly based on CT and MR anatomic morphological images, but characteristics of tumor biology changes can be observed earlier than the morphological changes. In the recent years, with the development of diffusion weighted imaging (DWI), its value in clinical application has been continuously explored, and it has been increasingly used for quantitative evaluation the diffusion of water molecular and microcirculation perfusion of blood flow in tumor tissue, with some progress in evaluating the tumor response. This paper mainly reviewed the recent research findings of DWI on locoregional interventional treatment for HCC, thereby providing guidance on clinical practice.
