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 assess the prognostic impact of frailty on elderly inpatients with heart failure.Methods:This prospective cohort study enrolled 121 in elderly patients with heart failure from Beijing Hospital, the General Hospital of the People's Liberation Army, and Beijing Tsinghua Changgung Hospital between September 2018 and April 2019.Patients were assessed for frailty using the Fried frailty phenotype and categorized into frail and non-frail groups.Follow-ups were conducted at 3-, 6-, and 12-months post-enrollment through clinic visits or phone calls to record adverse events.Composite endpoints include all-cause mortality and rehospitalization duo to deterioration of heart failure.Results:The study included 121 patients with an average age of 78.0±7.4 years, of whom 71(58.7%)were male and 57(47.1%)were classified as frail.Compared to the non-frail group, the frail group had lower estimated glomerular filtration rates[49.5±20.7 ml/(min·1.73m 2) vs.(64.0±27.1)ml/(min·1.73m 2)], lower scores in Basic Activities of Daily Living[5.0(4.0, 6.0) vs.6.0(5.0, 6.0)], Instrumental Activities of Daily Living[2.0(1.3, 7.8) vs.7.0(5.0, 8.0)], and Mini-Mental State Examination[26.0(16.0, 28.0) vs.27.0(22.3, 29.0)], all P<0.05.They also experienced longer hospital stays[10.5(6.0, 18.8)days vs.8.0(6.0, 11.8)days, P=0.008].During the follow-up period, the incidence of composite endpoint events was significantly higher in the frail group(43.9% vs.25.0%, P=0.029).Kaplan-Meier survival analysis demonstrated that the one-year incidence of composite endpoint events was significantly higher in the frail group( P=0.013).Multivariable Cox regression analysisindicated that frailty was an independent risk factor for composite endpoint events( HR=2.201, 95% CI: 1.089-4.447, P=0.028). Conclusions:Frailty is an independent risk factor for poor outcomes in elderly hospitalized patients with heart failure and should be considered a crucial factor in clinical assessment and treatment strategies.

Objective:To analyze the mechanism of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid in the treatment of gallstone and cholecystitis based on network pharmacology; To conduct a comparative analysis.Methods:The chemical components of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid and their drug targets were collected from Traditional Chinese Medicine Database and Analysis Platform (TCMSP). DAVID 6.8 database was used to search for the associated diseases of the drug targets. The disease targets of gallstone and cholecystitis were collected from GeneCards and other databases. The protein-protein interactions network was established based on the intersecting targets of three drugs and two diseases. KEGG enrichment analysis was performed based on the DAVID 6.8 database. Cytoscape 3.7.1 software was used to construct a complex network and topology analysis of component- target- disease between three drugs and diseases.Results:222 chemical components and 3 133 drug targets were collected for Jindan Tablets. 104 chemical components and 1 425 action targets were collected for Xiaoyan Lidan Tablets. 1 chemical component and 119 action targets were collected for ursodeoxycholic acid. The three drugs were associated with 31 diseases. 1 382 disease targets for gallstones and cholecystitis were collected. There were 237, 163 and 33 targets for gallstones and cholecystitis in the three drugs, of which 17 were shared by the three drugs and 20 were shared by Jindan Tablets and Xiaoyan Lidan Tablets. Based on the DAVID database, 113, 74 and 10 significant KEGG enrichment pathways were obtained for the three drugs respectively.Conclusions:The three drugs shared many targets and pathways in the treatment of gallstones and cholecystitis, which all had the function of regulating metabolism and inhibiting inflammatory response, while participating in apoptosis, oxidative stress and cancer pathology process. However, they had their own special effects, with Jindan Tablets favoring involving in the cancer process and inhibition of inflammation, and promoting angiogenesis. Xiaoyan Lidan Tablets and ursodeoxycholic acid focused on regulating cholesterol metabolism, and Xiaoyan Lidan Tablets also regulated steroid metabolism and inhibit inflammation, while ursodeoxycholic acid regulated bile acid metabolism.

Objective:To learn about the changes of the condition of coal-burning-borne endemic arsenism, the use of improved stoves and the formation of health-related behaviors in Shaanxi Province, and evaluate the effect of prevention and control measures.Methods:From 2015 to 2020, according to the "Implementation Plan for Monitoring Coal-burning-borne Endemic Arsenism in Shaanxi Province", regular field surveys were carried out in 4 natural villages, 2 counties in Ankang City and Hanzhong City, Shaanxi Province, to learn about the basic prevention and control situation in the monitoring village. Using the simple random sampling method, 10 families in each village were selected to investigate the use of stoves and the formation of health-related behaviors, and 5 of these families were selected to collect coal samples for arsenic content determination in accordance with the "Determination of Arsenic in Coal" (GB/T 3058-2008). According to the "Diagnosis of Endemic Arsenicosis" (WS/T 211-2015), the condition of the people exposed to high arsenic coal in the monitoring village was investigated. Urine samples of 30 adult patients (half males and half females) with arsenic poisoning were collected, the content of arsenic in urine was determined by the "Urine-Determination of Arsenic-Silver Diethyldithiocarbamate-Triethanolamine-Spectrophotometric Method" (WS/T 28-1996).Results:A total of 240 households were monitored in the past 6 years, and the quality conformance and correct utilization rates of improved stoves in the households monitored in the disease areas remained at 100.00% in 2018 - 2020. The utilization rate of clean energy increased from 75.00% (30/40) in 2015 to 100.00% (40/40) in 2018 - 2020 (χ 2trend = 25.5, P < 0.001). The 73.75% (177/240) of households using a variety of clean energy. From 2018 to 2020, the correct drying, storage and pre-processing washing rates of corn and pepper continued to reach 100.00% (40/40). The arsenic content of coal ( n = 120) in the disease areas was (118.09 ± 57.91) mg/kg, ranging from 16.70 to 280.94 mg/kg. The detection rate of arsenic poisoning decreased from 6.34% (231/3 646) in 2015 to 2.90% (109/3 754) in 2020 (χ 2trend = 121.8, P < 0.001), and no skin cancer or Bowen's disease was detected. The geometric mean of arsenic content in urine ( n = 720) was 0.038 1 mg/L, ranging from 0.000 5 to 0.312 9 mg/L. Conclusions:The condition of coal-burning-borne endemic arsenism areas in Shaanxi Province has reached the national elimination standard. The quality and correct utilization rate of improved stoves and the rate of using clean energy have increased. The healthy-related behaviors the people in the endemic areas have been basically formed. The prevention and control work has achieved good results.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objective:To evaluate the association of different biomarkers with frailty in elderly hospitalized patients.Methods:In this cross-sectional study, a total of 319 elderly patients aged 65 years or older hospitalized in Beijing Hospital between September 2018 and February 2019 were enrolled.Patients had a mean age of(75.0±6.6)years and 151(47.3%)were women.Based on the Fried phenotype, patients were divided into a non-frail group(244 cases, 76.5%)and a frail group(75 cases, 23.5%). The clinical characteristics and biomarker levels of the two groups were compared.The association of different biomarkers with frailty was evaluated by using the receiver operating characteristic(ROC)curve.The Youden index was used for the optimal cutoff values and the area under the curve(AUC)were calculated.AUCs of different biomarkers were compared to assess their correlations with frailty.Results:Hemoglobin, lipid levels(triglycerides, total cholesterol and low-density lipoprotein cholesterol), and prealbumin were significantly lower in the frail group than in the non-frail group( P<0.05), while N-terminal pro-B type natriuretic peptide(NT-proBNP)and high-sensitivity C reactive protein(hsCRP)levels were significantly higher than in the non-frail group( P<0.05). Thyrotropin(TSH)and free triiodothyronine(FT3)levels were significantly lower( P<0.05)and trans-triiodothyronine(rT3)was significantly higher( P<0.05)in the frail group.The combination of six biomarkers[hemoglobin, prealbumin, hsCRP, 25-dihydroxy vitamin D3[25(OH)D3], rT3 and NT-pro BNP]had the most powerful correlation with frailty(AUC=0.705, 95% CI: 0.652-0.755), but the correlation was not significantly different from that of the combination of 3 markers(hemoglobin, rT3 and hsCRP)(ROC=0.010, 95% CI: -0.0106-0.0306, P>0.05). Either of the two combinations was significantly better than the combination of 2 markers(hemoglobin and rT3)(ROC=0.143, 95% CI: 0.0406-0.245; ROC=0.153, 95% CI: 0.0498-0.256; all P<0.01). Conclusions:Hemoglobin, lipids, prealbumin, TSH and FT3 levels decrease while NT-proBNP and hsCRP levels increase in elderly hospitalized frail patients.The 6-biomarker combination[hemoglobin, prealbumin, hsCRP, 25(OH)D3, rT3 and NT-pro BNP]and 3-biomarker combination(hemoglobin, rT3 and hsCRP)have better correlation with frailty than the 2-biomarker combination(hemoglobin and rT3).

OBJECTIVE: To explore the characteristics and rules of acupoint sensitization phenomena based on knee osteoarthritis (KOA), one of the clinical dominant diseases of acupuncture-moxibustion. METHODS: In combination with literature and expert experiences, the acupoints with the highest use frequency in treatment of KOA were screened, e.g. Heding (EX-LE 2), Liangqiu (ST 34), Mingmen (GV 4), Neixiyan (EX-LE 4), Ququan (LR 8) and Dubi (ST 35). In 814 patients with KOA and 217 healthy subjects, the acupoint temperature, mechanic pain threshold and pressure pain threshold were detected separately. Using machine learning method, the sensitization was judged at each acupoint. RESULTS: Compared with healthy subjects, the acupoint temperature was increased and the mechanic pain threshold and pressure pain threshold were reduced in KOA patients (P<0.05). Besides, the cut-off value was presented to distinguish whether the acupoint was sensitized or not. The results of machine learning showed that the highest prediction accuracy of acupoint sensitization was 86.7% (Shenshu [BL 23]) and the lowest one was 73.9% (Heding [EX LE 2]). The prediction accuracy at the third clinical stage trial was higher, the highest was 93.3% (Ququan [LR 8]) in KOA patients. CONCLUSION It is confirmed that the acupoint sensitization reflects the characteristics of disease and is correlative with the conditions of illness, which may provide the reference for the auxiliary diagnosis and condition assessment of KOA.
