Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

Objective:To compare the efficacy of different doses of tranexamic acid (TXA) for traumatic hemorrhagic shock (THS) in the early phase of trauma following acute exposure to high altitude in rabbits.Methods:Twenty-five healthy male New Zealand rabbits were randomly divided into plain control group ( n=5) and acute high-altitude THS group ( n=20) according to the random number table method. The plain control group did not undergo THS modeling throughout the experiment while the acute high-altitude THS group was raised in a hypoxia simulation chamber with a volume fraction of 10% for 3 days to establish the THS model. Based on the different doses of TXA administered intravenously at 30 minutes after THS modeling, the acute high-altitude THS group was further divided into four subgroups: acute high-altitude THS+0 mg/kg TXA subgroup, acute high-altitude THS+45 mg/kg TXA subgroup, acute high-altitude THS+90 mg/kg TXA subgroup and acute high-altitude THS+135 mg/kg TXA subgroup, with 5 rabbits in each. The vital signs [mean arterial pressure (MAP), heart rate, rectal temperature] and blood cell counts [red blood cell count (RBC), platelet count (PLT)], 4 coagulation parameters [fibrinogen (FIB), D-dimer, activated partial thromboplastin time (APTT), prothrombin time (PT)], thromboelastography [clotting reaction time (R value), clot formation time (K value), maximum amplitude (MA value)], syndecan-1, inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)], and plasminogen activator inhibitor-1 (PAI-1) were recorded before blood loss, at 30 minutes and 120 minutes after blood loss. At 6 hours after THS, the lungs, terminal ileum, and kidneys of the rabbits were collected to observe tissue damage, and the wet/dry weight ratio (W/D) and total water content (TLW) of the lung tissue were measured. Results:(1) Vital signs: Before blood loss, there were no significant differences in MAP, heart rate, or rectal temperature between the acute high-altitude THS subgroups and the plain control group ( P>0.05). At 30 minutes and 120 minutes after blood loss, the acute high-altitude THS subgroups exhibited significantly lower MAP, heart rate, and rectal temperature compared to those in the plain control group ( P<0.05). No significant differences were observed in MAP, heart rate or rectal temperature among the acute high-altitude THS subgroups at any time point ( P>0.05). In the acute high-altitude THS subgroups, MAP, heart rate and rectal temperature were significantly decreased at 30 minutes and 120 minutes after blood loss compared to those before blood loss ( P<0.05); At 120 minutes after blood loss, these parameters were further significantly decreased compared to those at 30 minutes after blood loss ( P<0.05).

At 120 minutes after blood loss, syndecan-1, IL-6, TNF-α, and PAI-1 were significantly higher in the acute high-altitude THS subgroups compared to those in the plain control group ( P<0.05). Among them, the acute high-altitude THS+0 mg/kg TXA group exhibited significantly higher levels of syndecan-1, IL-6, TNF-α, and PAI-1 compared to the other acute high-altitude THS subgroups ( P<0.05). The acute high-altitude THS+45 mg/kg TXA subgroup had significantly higher syndecan-1, IL-6, and TNF-α compared to those in the acute high-altitude THS+90 mg/kg TXA and acute high-altitude THS+135 mg/kg TXA subgroups ( P<0.05), with no significant difference in PAI-1 ( P>0.05). No significant differences were observed in syndecan-1, IL-6, TNF-α or PAI-1 between the acute high-altitude THS+90 mg/kg TXA and acute high-altitude THS+135 mg/kg TXA subgroups ( P>0.05). (6) Tissue injury: At 6 hours after THS, acute high-altitude THS+0 mg/kg TXA group exhibited significant interstitial thickening of the lung with extensive inflammatory cell infiltration, localized loss of intestinal brush border accompanied by cellular disruption, and marked structural disruption of renal corpuscles with focal cellular injury and necrosis. At 6 hours after THS, the acute high-altitude THS+0 mg/kg TXA subgroup exhibited significantly higher lung injury scores, Chiu′s intestinal injury scores, and kidney injury scores compared to those of the other subgroups ( P<0.05). No significant differences were observed in the tissue injury scores of the lungs, intestines and kidneys among the other subgroups ( P>0.05). The acute high-altitude THS+0 mg/kg TXA subgroup also had significantly higher lung W/D and TLW compared to those in the other subgroups ( P<0.05).

Conclusions:At 3 days after acute exposure to high altitude, rabbits show a hypercoagulable state of the blood, accompanied by endothelial barrier dysfunction. At 30 minutes after the induction of acute high-altitude THS, a single slow intravenous bolus injection of TXA at doses of 90 mg/kg and 135 mg/kg is more effective in improving coagulation and fibrinolysis function, inflammatory response, endothelial injury, and reduced the risk of pulmonary edema than that at a dose of 45 mg/kg.

Objective To explore the role of indole-3-propionic acid(IPA)in the pathogenesis of metabolic associated fatty liver disease(MAFLD)induced by high-fat diet(HFD)in order to reveal the role and related mechanism of adipose tissue metabolism in the process.Methods A mouse model of MAFLD was induced by HFD.Male C57BL/6J mice(6～7 weeks old)were randomly divided into control group(CON),HFD group,and HFD+IPA intervention group(HFD+IPA).The CON group was fed with control diet,and the HFD group and HFD+IPA group were fed with 60％of high-fat diet.The experiment period was 12 weeks,and IPA was administered at 20 mg/(kg·d)for 6 weeks starting from the 7th week.The body weight and food intake of each group were monitored weekly.After the intervention,the body composition of mice was detected by animal body composition analyzer.After the mice were euthanized,the morphological and structural changes in the liver and adipose tissues were observed by HE staining,the indicators relevant to lipid metabolism in the serum,l iver and adipose tissues were detected by automatic blood biochemical analyzer and biochemical kits,and the mRNA expression changes of lipid metabolism and inflammation related genes were detected by qRT-PCR.Results Compared with the CON group,the HFD group had significantly increased body weight and body fat percentage,obvious lipid deposition in the liver,obviously elevated serum alanine aminotransferase,aspartate aminotransferase,liver triglyceride and total cholesterol levels(P＜0.05),and raised mRNA levels of liver fatty acid transporter CD36(P＜0.05),while IPA intervention significantly reversed the above changes(P＜0.05).IPA intervention significantly inhibited the HFD-induced enlargement of visceral and brown fat cells,reduced the content of visceral adipose tissue(VAT)and serum level of free fatty acids(P＜0.05),and increased the mRNA expression levels of VAT lipolysis(HSL,CGI58),browning genes(Cidea,ND5,UCP1,Prdm16)(P＜0.05),as well as those of brown adipose tissue(BAT)lipolysis(HSL,ATGL)and fatty acid beta oxidation(Cpt1a,PPARα)genes(P＜0.05).Meanwhile,the mRNA levels of TNF-α,IL-1β,CXCL1 and CCL2 in VAT and BAT were decreased after IPA intervention(P＜0.05).Conclusion IPA can improve the occurrence of MAFLD induced by HFD,and its mechanism may be closely associated with its regulation of BAT and VAT morphology,and the mRNA expression of metabolic function and inflammation related genes.

Gliomas tend to have a poor prognosis and are the most common primary malignant tumors of the central nervous system. Compared with patients with other cancers, glioma patients often suffer from increased levels of psychological stress, such as anxiety and fear. Chronic stress (CS) is thought to impact glioma profoundly. However, because of the complex mechanisms underlying CS and variability in individual tolerance, the role of CS in glioma remains unclear. This review suggests a new proposal to redivide the stress system into two parts. Neuronal activity is dominant upstream. Stress-signaling molecules produced by the neuroendocrine system are dominant downstream. We discuss the underlying molecular mechanisms by which CS impacts glioma. Potential pharmacological treatments are also summarized from the therapeutic perspective of CS.

Objective:To investigate the safety and short-term efficacy of yttrium-90 [ 90Y] resin microspheres transarterial radioembolization (TARE) for the treatment of initial unresectable malignant hepatic tumor. Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients with initial unresectable malignant hepatic tumor who were admitted to The First Affiliated Hospital of Army Medical University from June 2022 to June 2023 were collected. All patients were males, aged (57±4)years. Measurement data with normal distribution were represented as Mean± SD, and comparison before and after treatment within the group was conducted using the paired t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison before and after treatment within the group was conducted using the paired rank sum test. Count data were described as absolute numbers or proportions. Results:(1) Pre-treatment assessment. All 10 patients completed pre-treatment assessment, with 8 cases undergoing once of technetium 99-polymerised protein perfusion test and 2 cases under-going ≥ twice of technetium 99-polymerised protein perfusion test. The ratio of uptake of techne-tium 99-polymerised protein in tumor tissue to normal tissue, the hepatopulmonary shunting ratio and the therapeutic requirement of 90Y resin microspheres in 10 patients were 5.8±1.2, 4.8%±0.8% and (1.10±0.20)GBq, respectively. (2) Treatment strategy of 90Y resin microspheres TARE. Of the 10 patients, cases treated with whole tumor radioembolisation, radioembolisation of the main target lesion+non-target lesion radiofrequency ablation, radioembolisation of the main target lesion+non-target lesion iodine-125 particles implantation, radioembolisation of the liver lobe or liver segment were 6, 2, 1, 1, respectively. During the treatment period, one elderly case did not receive target therapy combined with immunotherapy due to intolerance, and the remaining 9 cases received target therapy combined with immunotherapy. Of the 10 patients, there were 7 cases receiving once of 90Y resin microspheres TARE, and 3 cases receiving twice of 90Y resin microspheres TARE. (3) Follow-up. All 10 patients were followed up for 4.5(range, 3.0-12.0)months. During the follow-up, none of patient had adverse event associated with 90Y resin microspheres TARE. The tumor diameter, alpha-fetoprotein (AFP), abnormal prothrombin, alanine aminotransferase (ALT), aspartate amino-transferase (AST), albumin (Alb), total bilirubin (TBiL), glutamyltransferase (GGT) of the 10 patients were 96(72,135)mm, 26(6,833)μg/L, 290(56,2 997)Au/L, (36±13)IU/L, (41+16)IU/L, (40±4)g/L, (15.3±4.1)μmol/L, (99±68)IU/L before receiving 90Y microspheres TARE.

In order to study the involatile chemical components in Moutai-flavored distiller’s grains, the Moutai-flavored distiller’s grains were extracted with 75% ethanol, followed by extraction with petroleum ether, ethyl acetate, and n-butanol. Silica gel, ODS, sephadex LH-20, and preparative HPLC were used to separate and identify the petroleum ether and ethyl acetate layers.ESI-MS and NMR were used to identify the compounds, which were respectively identified as pentadecanoic acid (1), palmitic acid (2), trans-2-decenoic acid (3), n-nonyl octadecanoate (4), ethyl octadecanoate (5), ethyl linoleate (6), luric acid (7), 1, 3-dicaprylyl-2-linoleylglycerin (8), cyclic (phenylalanine-proline) (9), cyclo-(proline-leucine) (10), 3, 6-bis-(2-methylpropyl)-2,5-dione piperazine (11), 4-hydroxyphenethyl alcohol (12), 2,4-dihydroxybenzoic acid (13), stigmasterol (14), 2-furancarboxylic acid (15), valine (16), L-alanine acyl-L-proline (17), dihydroquercetin (18), 5, 7, 3'', 4''-tetrahydroxyflavonoids (19), quercetin (20), and naringenin (21). Compounds 1-21 were isolated from distiller’s grains for the first time.

OBJECTIVE：To study “Qi-invigorating”effect and its possible mechanism of total saponins of Astragalus membranaceus on rats with Qi-deficiency ，and to provide reference for elucidating the material basis of “Qi-invigorating”effect of A. membranaceus . METHODS ：Forty male Wistar rats were randomly divided into normal group ，model group ，positive control group [Buzhong yiqi pills ，4.5 g/（kg·d）]，A. membranaceus total saponins high-dose and low-dose groups [ 252，28 g/（kg·d），by the amount of total saponins] according to body weight ，with 8 rats in each group. Except for normal group ，the model of Qi-deficiency was made in other groups by the method of “diet disorder+fatigue ”. At the same time ，administration groups were given relevant medicine intragastrically ，and normal group and model group were given constant volume of water，once a day ，for consecutive 21 days. After last administration ，the general situation of rats was observed ；the body weight ，spleen index and thymus index of rats were detected ；weight-bearing swimming time was recorded ；the levels of spleen T lymphocyte subsets CD 3 and CD 4，the levels of ATP and ADP in liver tissue ，serum levels of ALB ，RBC and HBG in blood as well as the serum levels of SOD，MDA，lactate，LDH，CK，IL-2，IL-12 and TNF-α were all detected. RESULTS：Compared with normal group ，body weight，thymus index ，spleen index ，weight-bearing swimming time ，the level of spleen T lymphocyte subsets CD 3，ATP，ADP， ALB，IL-2 and IL- 12 were decreased or shortened significantly in model group （P＜0.05 or P＜0.01）. The levels of MDA ， lactate，CK and TNF-α were increased significantly （P＜ 0.05）. Compared with model group ，body weight ，spleen index，weight-bearing swimming time ，the level of spleen T lymphocyte subsets CD 3 and the levels of ATP ，ADP，ALB， RBC and IL- 2 were increased significantly or prolonged（P＜0.05）；while the levels of MDA ，lactate，CK and TNF-α were decreased significantly in A. membranaceus total saponins high-dose group（P＜0.05 or P＜0.01）.Weight-bearing swimming time ，the levels of ATP ，ADP and IL- 2 in A. membranaceus total saponins low-dose group were increased significantly or prolonged （P＜0.05 or P＜0.01），while the levels of MDA ，lactate，CK and TNF-α were decreased significantly （P＜0.05 or P＜0.01）. Compared with positive control group ，spleen index ，spleen T lymphocyte subsets CD 3，weight-bearing swimming time and ATP level of A. membranaceus total saponins high-dose group were increased significantly or prolonged （P＜0.05 or P＜0.01），while MDA levels of A. membranaceus total saponins high-dose and low-dose groups were decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：A. membranaceus total saponins can reduce the body ’s accumulation of blood lactic acid ，the activity of CK ，the level of lipid peroxide and regulate immunity to tonify Qi ，delay fatigue and improve exercise ability.

The pathophysiological process of immune inflammatory response after severe trauma is extremely complex, especially manifested in the dynamic changes. In the physiological response state, the inflammatory and anti-inflammatory conditions are in a dynamic balance. The immune inflammatory response is relatively stable, avoiding excessive inflammatory reactions or immunosuppression and reducing further damage to the body. In the pathological response state, the dynamic balance between inflammatory and anti-inflammatory is broken, and it can also lead to persistent inflammatory-immunosuppression-catabolism syndrome (PICS). As a result, it increases serious complications such as uncontrolled inflammatory reactions, sepsis, multiple organ dysfunction syndrome (MODS), and multiple organ failure (MOF). Current researches on post-traumatic immune inflammatory response have also expanded to the genetic level, indicating that the over-expression of genes and the generation and increase of immune response media are likely to be the key reasons for the disorder of immune inflammatory response. The author reviews the research progress of immune inflammatory response mechanism and related clinical intervention after severe trauma, in order to summarize the previous research results and explore the future research direction.
