OBJECTIVE To investigate the clinical characteristics and risk factors for batroxobin-related severe hypofibrinogenemia （HFIB） and construct a risk prediction model. METHODS A retrospective analysis was conducted on inpatients treated with batroxobin in the First Medical Center of a tertiary hospital from January 1， 2020， to December 31， 2024. Patients were categorized into non-severe HFIB group and severe HFIB group based on the severity of HFIB. Univariate and multivariate Logistic regression analyses were performed to identify the independent influencing factors for batroxobin-related severe HFIB. A nomogram was developed using the “rms” package in R 4.5 software. The predictive performance of the model was evaluated using the receiver operating characteristic curve. Calibration was assessed via the Bootstrap resampling method， and goodness-of-fit was evaluated with the Hosmer-Lemeshow test. RESULTS A total of 1 472 patients were included in this study. Of these， 1 445 developed HFIB， yi elding an incidence of 98.17%. Furthermore， 895 were classified as severe HFIB， accounting for 60.80% of the cohort. Multivariate Logistic regression analysis showed that increased age， high initial dose per 10 kg body weight， use of maintenance dose， and concomitant glucocorticoid use were independent risk factors for batroxobin-related severe HFIB， while high baseline fibrinogen （FIB） level was identified as a protective factor. The model demonstrated an area under the curve of 0.760 （95% CI： 0.735-0.785）. The mean absolute error of the calibration curve was 0.006. The P value of the Hosmer-Lemeshow test was 0.609. CONCLUSIONS Batroxobin can rapidly and significantly reduce FIB levels and carries a risk of inducing severe HFIB. Patients with advanced age， high initial dose per 10 kg body weight， use of maintenance dose and concomitant glucocorticoid use had a higher risk of batroxobin-related severe HFIB， while high baseline FIB level had a lower risk of batroxobin-related severe HFIB. The risk prediction model developed based on these factors can be used to predict the likelihood of batroxobin-related severe HFIB.

The traditional Chinese medicine （TCM） myocardial infarction （MI） unit is a standardized， regulated， and continuous integrated care unit guided by TCM theory and built upon existing chest pain centers or emergency care units. This unit emphasizes multidisciplinary collaboration and forms a restructured clinical entity without altering current departmental settings， offering comprehensive diagnostic and therapeutic services with full participation of TCM in the treatment of MI. Its core medical model is patient-centered and disease-focused， providing horizontally integrated TCM-based care across multiple specialties and vertically constructing a full-cycle treatment unit for MI， delivering prevention， treatment， and rehabilitation during the acute， stable， and recovery phases. Additionally， the unit establishes a TCM-featured education and prevention mechanism for MI to guide patients in proactive health management， reduce the incidence of myocardial infarction， and improve quality of life.

Objective To investigate the effect of Jiaotaiwan on brain insulin-PI3K/AKT pathway in a mouse model of Alzheimer's disease(AD).Methods Fifty 3-month-old male APP/PS1 double transgenic mice were randomized into AD model group,low-,medium-and high-dose Jiaotaiwan treatment groups,and donepezil treatment group.Cognitive functions of the mice were assessed using water maze and open field tests,and neuronal pathologies were observed with HE staining and Nissl staining;immunohistochemistry was used to detect amyloid Aβ deposition in the brain.Fasting serum insulin levels of the mice were measured,and the expressions of Aβ42,insulin-PI3K/AKT pathway components and downstream glucose transporters in the brain tissue were detected with RT-qPCR and Western blotting.Results The AD mouse models exhibited obvious impairment of learning and memory abilities,significantly reduced hippocampal neurons,and obvious Aβ amyloid plaques in the brain tissue with increased Aβ42 protein expression(P<0.05)and insulin resistance index,decreased hippocampal PI3K expressions,lowered expressions of AKT and InR,reduced expressions of GLUT1,GLUT3,and GLUT4,and increased expression of GSK3β in both the hippocampus and cortex.Treatment with Jiaotaiwan and donepezil both effectively improved memory ability of the mouse models,increased the number of hippocampal neurons,reduced Aβ amyloid plaques and increased the expressions of PI3K,AKT,InR,GLUT1,GLUT3 and GLUT4 in the hippocampus and cortex.Conclusion Jiaotaiwan improves learning and memory abilities of APP/PS1 double transgenic mice and delay the development of AD by activating the PI3K/AKT pathway and regulating the expression levels of its downstream GLUTs in the brain.

The bone-touching acupuncture method, as one of the five-body acupuncture techniques, is widely used and highly effective in the treatment of brain diseases, though its theoretical foundation has been lacking. This paper explores the close connection between bones and the brain in both physiological and pathological states, as described in traditional Chinese medicine (TCM) classics, and explains the "bone-brain axis" concept within the framework of TCM. It summarizes the effects and characteristics of the five-body acupuncture techniques, traces the origins and modern applications of the bone-touching acupuncture method, and discusses its theoretical basis for treating brain diseases. The aim is to provide a reference for future clinical and mechanistic research on bone-touching acupuncture in brain disease treatment and to offer new perspectives and approaches for acupuncture treatment of brain diseases.

Objectve:To study the effect of gabexate mesylate (GM) on acute lung injury (ALI) in septic rats based on metabonomics.Methods:Fifty-seven SD rats were randomly(random number) divided into three groups: sham operation group (SC group), cecal ligation puncture induced septic ALI group (CLP group), and intraperitoneal administration of GM at 1 h after CLP (CLP-GM group). Twenty-four h after the experiment, the survival of rats in the SC, CLP and CLP-GM groups was observed, the lung tissue was collected for HE staining to observe the pathological changes, and the plasma was collected for metabonomics detection to analyze the characteristics of metabolites.Results:Compared with the SC group, the infiltration of inflammatory cells in the lung tissue of rats in the CLP groupincreased significantly, and the metabolic profile of plasma changed significantly. However, the pathological and metabonomic characteristics of the CLP-GM group showed that the above changes were reversed after the application of GM. Twelve major differential metabolites were found in plasma. The metabolic pathways involved in the disorder included biosynthesis of phenylalanine, tyrosine and tryptophan, phenylalanine metabolism and sphingolipid metabolism.Conclusions:GM may improve septic ALI by regulating amino acid metabolism, sphingolipid metabolism and other metabolic pathways.

Objective:To observe the changes of arterial blood gas indexes in pigs with the free-field primary blast lung injury (PBLI) model, and to explore the value of arterial blood gas indexes in predicting moderate to severe PBLI.Methods:Nine adult healthy Landrace pigs were selected to construct the pig free-field PBLI model. Arterial blood samples were taken 15 minutes before the explosion (before injury) and 10, 30, 60, 120, and 180 minutes after the explosion (after injury). Arterial blood gas indexes and pulse oxygen saturation (SpO 2) were measured, compare the changes of blood gas analysis indexes and SpO 2 levels at different time points, and observe the changes of gross injury scores and pathological injury scores of lung tissue. Analyze the correlation between the blood gas indicators. Results:As time prolonged, at each time point, pH, arterial partial pressure of oxygen (PaO 2), and SpO 2 were lower than those before the injury, and blood lactic acid (Lac) and arterial partial pressure of carbon dioxide (PaCO 2) were higher than those before the injury. Compared with that before the injury, the pH value in the blood decreased significantly 10 minutes after the injury (7.39±0.06 vs. 7.46±0.02, P < 0.05), and the Lac increased significantly (mmol/L: 3.61±2.89 vs. 1.10±0.28, P < 0.05), and lasts until 180 minutes after injury (pH value: 7.37±0.07 vs. 7.46±0.02, Lac (mmol/L): 2.40±0.79 vs. 1.10±0.28, both P < 0.05); while PaO 2 and SpO 2 decreased significantly at 180 minutes after injury [PaO 2 (mmHg, 1 mmHg = 0.133 kPa): 59.40±10.94 vs. 74.81±9.39, P < 0.05; SpO 2: 0.75±0.11 vs. 0.89±0.08, P < 0.05], PaCO 2 increased significantly (mmHg: 56.17±5.38 vs. 48.42±4.93, P < 0.05). Correlation analysis showed that the gross injury score of lung blast injury animals was positively correlated with the pathological injury score ( r = 0.866, P = 0.005); PaO 2 and SpO 2 were positively correlated ( r = 0.703, P = 0.000); pH value and Lac were negative Correlation ( r = -0.400, P = 0.006); pH value is negatively correlated with PaCO 2 ( r = -0.844, P = 0.000). Conclusion:This study successfully established a large mammalian free-field PBLI model, arterial blood gas analysis is helpful for the early diagnosis of PBLI, whether SpO 2 can be used to evaluate the severity of lung injury remains to be further verified.
