epsis is a systemic inflammatory response syndrome triggered by infection， and its high mortality rate is closely associated with immune imbalance， particularly the imbalance in the differentiation of helper T cell （Th） cell subsets [Th1， Th2， Th17， regulatory T cell （Treg） ] . In recent years， traditional Chinese medicine （TCM）， with its characteristics of multi-component and multi-target actions， has demonstrated unique advantages in regulating Th cell differentiation and function， as well as correcting immune imbalances in sepsis， offering new perspectives for immunotherapy of sepsis. This review summarizes relevant studies on the regulation of Th cell differentiation for sepsis treatment by TCM monomers and active ingredients （such as Astragalus membranaceus ， Scutellaria baicalensis ， Coptis chinensis ， Rheum palmatum ， Ganoderma lucidum ， Ginkgo biloba ， and Cistanche deserticola ）， the alcohol extract of Dai Baijie， and TCM formulas and preparations categorized as blood-activating and stasis-removing， purgative and laxative， warming and tonifying yang， and tonifying qi and nourishing yin. The results indicate that these TCM monomers， active ingredients， extracts， formulas， and preparations can regulate the Th1/Th2 and Th17/Treg balance， target the differentiation balance of Th cell subsets， alleviate inflammatory responses， or improve immune suppression， thereby exerting therapeutic effects on sepsis.

Objective: To explore the association between peer victimization and psychotic like experiences (PLEs) among junior high school students, so as to provide a scientific basis for preventing adolescent PLEs. Methods: In January 2024, a method of combining convenient sampling with cluster sampling was used to survey 2 760 students from two ordinary junior high schools in southern Anhui Province (Susong Country,Anqing City). The Community Assessment of Psychic Experiences (CAPE) and the Adolescent Peer Bullying Scale were employed to assess PLEs with different symptoms and peer victimization (verbal, physical, relational, and cyberbullying). Multivariate Logistic regression models analyzed the associations of different types peer victimization and PLEs with different symptoms. Results: The prevalence of PLEs was 17.5%, with delusional (15.4%) and hallucinatory (7.4%) symptoms being most common. Peer victimization was reported by 51.3% of students (49.6% victims, 19.5% perpetrators), with verbal victimization being most frequent (42.4% victims, 15.5% perpetrators) and cyberbullying least frequent (6.0% victims, 1.9 % perpetrators). Compared to students without bullying,students exposed to bullying showed significantly higher rates of delusional ( χ 2=29.09-127.22), hallucinatory ( χ 2=27.23-72.29), and overall PLEs ( χ 2=34.32-127.25) (all P <0.01). After adjusting for relevant confounding factors,the multiple Logistic regression model revealed verbal victimization increased risks of delusions ( OR=1.59, 95%CI =1.22-2.09), hallucinations ( OR=1.94, 95%CI =1.33-2.84), and overall PLEs ( OR=1.62, 95%CI = 1.26- 2.09); relational victimization was associated with delusions ( OR=1.83, 95%CI =1.40-2.39) and PLEs ( OR=1.65, 95% CI = 1.28-2.13); physical victimization correlated with hallucinations ( OR=1.64, 95%CI =1.12-2.40) and PLEs ( OR=1.41, 95%CI =1.06-1.87) (all P <0.05). Conclusion Specific types of peer victimization are differentially associated with PLEs, with relational victimization demonstrating the strongest association.

Objective:To compare the anticoagulant efficacy and safety between argatroban and heparin in patients with liver failure complicated with hepatic encephalopathy undergoing artificial liver treatment.Methods:A total of 207 patients with liver failure complicated with hepatic encephalopathy who received artificial liver treatment in the intensive care unit (ICU) of Wuxi No.5 People′s Hospital from January 2021 to October 2024 were enrolled, including 105 cases in the argatroban group and 102 cases in the heparin group. Changes in coagulation function, hemoglobin (Hb), platelet (PLT) count, and model for end-stage liver disease (MELD) score before and after artificial liver treatment were compared between the two groups. The formation of deep vein thrombosis in the lower extremities, coagulation in the extracorporeal circulation circuit and plasma separator, bleeding at the deep venous catheter site were compared between the two groups. The 28-day survival outcome of the patient were recorded. Two independent sample t-test, rank sum test, and chi-square test were used for statistical comparisons, and the Kaplan-Meier method and log-rank test were used to analyze the survival rate of patients. Results:There were no statistically significant differences in activated partial thromboplastin (APTT), international normalized ratio (INR), Hb and PLT count before and after artificial liver treatment in the argatroban group ( Z=-1.74, -1.80, -1.26 and -0.52, respectively, all P>0.05), while the MELD score after treatment was lower than that before treatment and the difference was statistically significant ( t=6.49, P<0.001). After artificial liver treatment, the APTT in the argatroban group was 47.10(42.65, 51.90) s, which was shorter than that in the heparin group (56.05(50.02, 63.00) s). The INR, Hb, and PLT count in the argatroban group were 2.00(1.65, 2.54), 98.00(88.00, 112.00) g/L, and 92.00(75.50, 106.00)×10 9/L, respectively, which were all higher than those in the heparin group, which were 1.56(1.22, 1.93) g/L, 90.50(80.00, 104.75) g/L, and 74.00(64.75, 99.50)×10 9/L, respectively. The differences were all statistically significant ( Z=-7.16, -5.28, -3.05 and -3.32, respectively, all P<0.05). There was no statistically significant difference in MELD scores between the two groups ( P=0.250). The incidence of coagulation in the extracorporeal circulation circuit and plasma separator and bleeding at the deep venous catheter site in the argatroban group was 5.71%(6/105) and 1.90%(2/105), respectively, which were both lower than those in the heparin group (14.71%(15/102) and 9.80%(10/102), respectively). The differences were both statistically significant ( χ2=4.59 and 5.91, respectively, both P<0.05). At the end of the 28-day follow-up, the mortality rates in the argatroban group and the heparin group were 22.9%(24/105) and 34.3%(35/102), respectively, and the difference was not statistically significant ( χ2=3.33, P=0.068). There was no statistically significant difference in the 28-day survival rate between the argatroban group and the heparin group ( χ2=2.09, P>0.05). Conclusions:Argatroban has a relatively minor impact on PLT count and Hb when it is used in artificial liver treatment for patients with liver failure complicated with hepatic encephalopathy. The incidence of coagulation in extracorporeal circulation circuits and plasma separators is low, and the risk of bleeding at the deep venous catheters is low. Argatroban is highly safe, which provides a new anticoagulation option for patients with a high risk of bleeding.

Objective:To explore the correlation and predictive value of the blood urea nitrogen to serum albumin ratio (BAR) in the development of sepsis among patients with acute-on-chronic liver failure (ACLF).Methods:A total of 410 patients diagnosed with ACLF who were admitted to Wuxi Fifth People′s Hospital between January 1st, 2020 and December 31st, 2024 were enrolled in this study. Demographic information, laboratory test indicators, and other clinical data were retrospectively analyzed. Participants were stratified into two groups using a 6∶4 allocation ratio, comprising a training set of 246 patients and a validation set of 164 patients, the clinical data of two groups were compared. Logistic regression was employed to evalute the influencing factors of sepsis during hospitalization in ACLF patients. Additionally, the predictive value of different factors for sepsis occurrence was evaluated using receiver-operating characteristic curve analysis. DeLong test was used to compare the area under the curve.Results:The comparison of baseline data between the training set and the validation set revealed no statistically significant differences (all P>0.05). A total of 197 sepsis cases were observed during the study period. Multivariate logistic regression analysis revealed that both BAR and the sequential organ failure assessment (SOFA) score were independent influencing factors for sepsis development in ACLF patients (odds ratio ( OR)=1.274, 95% confidence interval (95% CI) 1.075 to 1.510, P=0.005; OR=1.142, 95% CI 1.038 to 1.256, P=0.006). In the training set, the area under the curve (AUC) of BAR for predicting sepsis in ACLF patients was 0.802, which was superior to that of the SOFA score (AUC=0.706) ( Z=2.16, P=0.031). The validation set showed the predictive ability of BAR with an AUC of 0.726, which was superior to the SOFA score′s performance (AUC=0.606) ( Z=2.28, P=0.023). Conclusions:BAR could independently predict sepsis development in ACLF patients with significant prognostic value. BAR could be used as a clinically useful biomarker for sepsis risk stratification.

OBJECTIVES: To evaluate the clinical efficacy of human biological dressing (human acellular dermal matrix) transplantation in the management of refractory wounds among middle-aged and elderly patients. METHODS: A retrospective observational study was conducted involving 104 middle-aged and elderly patients (74 males, 30 females; aged 56-95 years) with refractory wounds treated at the First Affiliated Hospital of Wenzhou Medical University from January 2023 to December 2024. Following debridement, wound areas ranged from 1.0 to 48.0 cm². All patients received vacuum sealing drainage for 7 days, followed by human biological dressing transplantation. Subsequently, depending on the wound condition and the patient's preference, autologous skin grafting (ASG) or wound dressing changes were employed to promote wound healing. Outcome measures included: post-human biological dressing coverage of exposed tendons/bones and occurrence of tendon infection/osteomyelitis; survival rate of ASG at postoperative day 7; healing time in patients managed with wound dressing changes alone; patient satisfaction; and changes in pain intensity, sleep disturbance, and anxiety scores assessed before and 1 month after human biological dressing transplantation using the Edmonton Symptom Assessment Scale. RESULTS: After human biological dressing transplantation, 103 patients exhibited robust granulation tissue formation achieving complete coverage of the exposed tendons/bones, with no instances of tendon/bone necrosis, infection, or osteomyelitis. Among these, 51 patients underwent successful ASG at (44.4±13.0) d post-human biological dressing transplantation (success rate 100.00%), 52 patients achieved primary wound healing through dressing changes alone within (62.6±13.4) d post-human biological dressing transplantation. One patient experienced human biological dressing dissolution and detachment due to gluteal wound infection, resulting in non-healing. The overall cure rate was 99.04%. Patient satisfaction survey showed that 95 patients were very satisfied, 8 were satisfied, and 1 was dissatisfied (satisfaction rate 99.04%). Pain, sleep disturbance, and anxiety scores at 1 month post-human biological dressing transplantation were significantly reduced compared to pre-transplantation scores (all P<0.05). CONCLUSIONS Human biological dressing transplantation demonstrate excellent outcomes in treating refractory wounds in middle-aged and elderly patients and can serve as an effective therapeutic strategy for managing refractory wounds.

The translocator protein (TSPO) positron emission tomography (PET) can noninvasively detect neuroinflammation associated with epileptogenesis and epilepsy. This study explored the role of the TSPO-targeting radioligand [¹⁸F]F-TFQC, an m-trifluoromethyl ER176 analog, in the PET neuroimaging of epileptic rats. Initially, [¹⁸F]F-TFQC was synthesized with a radiochemical yield of 8%-10% (EOS), a radiochemical purity of over 99%, and a specific activity of 38.21 ± 1.73 MBq/nmol (EOS). After determining that [¹⁸F]F-TFQC exhibited good biochemical properties, [¹⁸F]F-TFQC PET neuroimaging was performed in epileptic rats at multiple time points in various stages of disease progression. PET imaging showed specific [¹⁸F]F-TFQC uptake in the right hippocampus (KA-injected site, i.e., epileptogenic zone), which was most pronounced at 1 week (T/NT 1.63 ± 0.21) and 1 month (T/NT 1.66 ± 0.20). The PET results were further validated using autoradiography and pathological analysis. Thus, [¹⁸F]F-TFQC can reflect the TSPO levels and localize the epileptogenic zone, thereby offering the potential for monitoring neuroinflammation and guiding anti-inflammatory treatment in patients with epilepsy.
