Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective To evaluate the biochemical indicators,nutritional status,and immune levels of pa-tients with pulmonary aspergillosis(PA)and other pulmonary diseases,and to construct a predictive model for PA so as to improve the diagnostic efficacy of clinical PA.Methods A total of 40 PA patients and 39 pa-tients with other pulmonary diseases who were hospitalized in the hospital from January 2020 to August 2022 were retrospectively analyzed.The expression trends and differences of serum 1,3-β-D Glucan(G test),galac-tomannan test(GM test),biochemical indexes,blood routine indexes and immune cell subsets were analyzed and compared.The receiver operating characteristic(ROC)curve and binary Logistic regression analysis were used to construct the predictive model for PA by the combination of clinical indicators.Results Serum GM test,G test,albumin,hemoglobin,hematocrit,lymphocytes,B lymphocytes,CD44 T lymphocytes and CD4/CD8 ratio displayed significant differences between PA patients and patients with other lung disease(P＜0.05).The levels of GM test in alveolar lavage fluid of PA patients were significantly higher than that in the serum,and the differences were statistically significant(P＜0.05).The ROC curve analysis showed that the GM test,as an independent predictor of PA,had good predictive accuracy[0.85＜area under the curve(AUC)＜0.95].Besides,albumin,natural killev cells,CD4+T lymphocytes and CD4/CD8 ratio had general predictive efficacy(0.70＜AUC＜0.85).The prediction efficacy of G test and B lymphocytes was poor(AUC＜0.70).The Logistic regression analysis showed that the combination of GM test and serum albumin could construct the optimal prediction model,and the prediction formula of the combined model was as fol-lows:Logit(P)=17.781× GM-0.131×albumin+1.394.The prediction accuracy of the combined model was 0.924(95％CI:0.865-0.982),the sensitivity was 87.5％,the specificity was 81.2％,and the cut off value was 17.781×GM-0.131×albumin-1.735.Conclusion This study retrospectively analyzed the differences in various clinical indicators between patients with PA and patients with other pulmonary diseases,and then screen the key clinical indicators as candidate predictors which displayed significantly different ex-pression between the two groups.The optimal prediction model for the diagnosis of PA is constructed by the combination of GM test and serum albumin through ROC curve and Logistic regression analysis.This model may significantly improve the diagnostic efficiency of PA in clinical,and provide the reference for the early di-agnosis and effective treatment of PA patients.

Major depressive disorder(MDD)is a prevalent con-dition associated with substantial impairment and low remission rates.Traditional antidepressants demonstrate delayed effects,low cure rate,and inadequate therapeutic effectiveness for man-aging treatment-resistant depression(TRD).Several studies have shown that ketamine,a non-selective N-methyl-D-aspartate receptor(NMDAR)antagonist,can produce rapid and sustained antidepressant effects.Ketamine has demonstrated efficacy for reducing suicidality in TRD patients.However,the pharmaco-logical mechanism for ketamine's antidepressant effects remains incompletely understood.Previous research suggests that the an-tidepressant effects of ketamine may involve the monoaminergic,glutamatergic and dopaminergic systems.This paper provides an overview of the pharmacological mechanism for ketamine's anti-depressant effects and discuss the potential directions for future research.

Glutamate,norepinephrine,and their receptors com-prise the glutamatergic and norepinephrine systems,which mu-tually affect each other and play essential roles in mediating vari-ous neuropsychiatric diseases.This paper reviews the functions of N-methyl-D-aspartate receptor(NMDA-R)and α2-adrenergic receptor(α2-AR)and their functional crosstalk at the molecular level in brain in common neuropsychiatric diseases,which would benefit our understanding of neuropathophysiology of psychiatric diseases,drug development and optimization of clinical neuro-psychopharmacology.

OBJECTIVE To heterologously express and purify bioscavenger organophosphorus hydrolase(OPH),and evaluate its ability to resist ethyl paraoxon poisoning in vivo.METHODS The Escherichia coli expression strain of OPH was constructed and purified by Ni-column affinity chroma-tography and gel filtration chromatography,and the purified product was identified by mass spectrometry.The enzyme activity and kinetic constants(Km,Vmax,kcat and kcat/Km)were measured using ethyl paraoxon as the substrate.Twelve SD rats were randomly divided into the experimental group and control group.The experimental group was given 1 mg·kg-1 of OPH solution by iv administration while the control group was given the same volume of normal saline.After administration,the two groups were immedi-ately sc administration with 2×LD50 ethyl paraoxon(0.86 mg·kg-1).The state of the rats was observed and the poisoning symptoms were scored.The survival rats were given 2×LD50 ethyl paraoxon every 24 h,and the survival curve and symptom score chart were drawn according to survival and poisoning symp-toms of the rats to evaluate the anti-organophosphorus poisoning ability of OPH.RESULTS The expres-sion strain of OPH in E.coli was successfully constructed.After two-step purification,a single band of OPH was obtained by sodium dodecyl sulphate-polyacrylamide gel electrophoresis,indicating that OPH had high purity,and the prepared protein sequence was consistent with the target protein.For OPH,Km=7.5×10-5 mol·L-1,Vmax=2.2×10-7 mol·L-1·s-1,kcat=158.4 s-1,kcat/Km=2.1×106 L·mol-1·s-1.The rats in the control group showed obvious poisoning symptoms after being given 2×LD50 ethyl paraoxon,and all rats died with in 15 min.The rats in the experimental group did not show poisoning symptoms after the first exposure,and the poisoning symptoms gradually deepened after continuous exposure until all the rats died on the 4th day.CONCLUSION OPH with high purity is successfully prepared in this study,and OPH could effectively resist ethyl paraoxon poisoning in rats.

The gut microbiota is a complex ecosystem composed of many bacteria and their metabolites.It plays an irreplaceable role in human digestion,nutrient absorption,energy supply,fat metabolism,im-mune regulation,and many other aspects.Exploring the structure and function of the gut microbiota,as well as their key genes and metabolites,will enable the early diagnosis and auxiliary diagnosis of disea-ses,new treatment methods,better effects of drug treatments,and better guidance in the use of antibiot-ics.The identification of gut microbiota plays an important role in clinical diagnosis and treatment,as well as in drug research and development.Therefore,it is necessary to conduct a comprehensive review of this rapidly evolving topic.Traditional identification methods cannot comprehensively capture the di-versity of gut microbiota.Currently,with the rapid development of molecular biology,the classification and identification methods for gut microbiota have evolved from the initial phenotypic and chemical identi-fication to identification at the molecular level.This review integrates the main methods of gut microbiota identification and evaluates their application.We pay special attention to the research progress on molec-ular biological methods and focus on the application of high-throughput sequencing technology in the iden-tification of gut microbiota.This revolutionary method for intestinal flora identification heralds a new chapter in our understanding of the microbial world.

Quercetin (Que) is a flavonoid compound widely distributed in nature with various biological activities.Its anti-inflammatory effect plays a crucial role in many diseases,closely related to its regula-tion of histone post-translational modifications.However,there have been no detailed reports on the anti-inflammatory effects of quercetin regulating histone post-translational modifications.In this study,we first investigated the effect of quercetin on the M1 macrophages polarization.The results showed that quercetin can significantly down-regulate the levels of interleukin-1β(IL-1β) and interleukin-6 (IL-6 ) in M1 macrophages.Next,we used the super stable isotope labeling by amino acids in cell culture (super-SI-LAC) method derived from SILAC technology based on mass spectrometry to systematically analyze the post-translational modification levels of histone in macrophages treated with quercetin.A total of 30 his-tone modification sites were quantified,of which 12 histone lysine acetylation marks were significantly downregulated and 4 lysine methylation sites were upregulated (fold change>1.2,P<0.05),and some sites were verified by Western blot (WB),which was consistent with the mass spectrometry results.In conclusion,a comprehensive analysis of quercetin on regulating macrophage histone modifications in this study provides reliable data references and new insights for studying its anti-inflammatory mechanism.

Objective:To analyze the effect of recombinant human thrombopoietin(rhTPO)on platelet(PLT)reconstitution after autologous peripheral blood stem cell transplantation(APBSCT)in patients with multiple myeloma(MM).Methods:The clinical data of 147 MM patients who were diagnosed in the First Affiliated Hospital of Soochow University and received APBSCT as the first-line therapy were retrospectively analyzed.According to whether rhTPO was used during APBSCT,the patients were divided into rhTPO group(80 cases)and control group(67 cases).The time of PLT engraftment,blood product infusion requirements,the proportion of patients with PLT recovery to ≥ 50 × 109/L and ≥ 100 × 109/L at+14 days and+100 days after transplantation,and adverse reactions including the incidence of bleeding were compared between the two groups.Results:There were no significant differences between the two groups in sex,age,M protein type,PLT count at the initial diagnosis,median duration of induction therapy before APBSCT,and number of CD34+cells reinfused(all P＞0.05).The median time of PLT engraftment in the rhTPO group was 10(6-14)days,which was shorter than 11(8-23)days in the control group(P＜0.001).The median PLT transfusion requirement in the rhTPO group during APBSCT was 15(0-50)U,which was less than 20(0-80)U in the control group(P=0.001).At+14 days after transplantation,the proportions of patients with PLT 2 50 × 109/L in the rhTPO group and the control group were 66.3％and 52.2％,while the proportions of patients with PLT ≥ 100 × 109/L were 23.8％and 11.9％,respectively,with no significant differences(all P＞0.05).At+100 days after transplantation,the proportion of patients with PLT ≥ 50 × 109/L in rhTPO group and control group was 96.3％and 89.6％,respectively(P＞0.05),but the proportion of patients with PLT ≥ 100 × 109/L in rhTPO group was higher than that in control group(75.0％vs 55.2％,P=0.012).There was no difference in the overall incidence of bleeding events in different locations during period of low PLT level of patients between the two groups.In rhTPO group,the rhTPO administration was well tolerated,and the incidences of abnormal liver and kidney function and infection were similar to those in the control group.Conclusion:When MM patients undergo first-line APBSCT,subcutaneous injection of rhTPO can shorten the time of platelet engraftment,reduce the transfusion volume of blood products,and be well tolerated,moreover,more patients have achieve a high level of PLT recovery after transplantation,which is very important for ensuring the safety of APBSCT and maintenance therapy.

Objective:Clot waveform analysis (CWA) of activated partial thromboplastin time (APTT) was used to rapidly identify patients with hemophilia A (HA) and lupus anticoagulant (LA) positive, and to explore the diagnostic efficacy of APTT-CWA in HA and LA-positive patients.Methods:From July 25, 2022, to December 28, 2023, 145 patients with APTT prolongation were admitted to the First Hospital of Jilin University. This group comprised 106 males and 39 females, with an average age of (29.3±15.8) years, among whom there were 94 clinically confirmed HA cases and 51 LA-positive cases. The retrospective analysis employed the Mann-Whitney U test to compare APTT results and CWA parameters between HA patients and LA-positive individuals.CWA parameters including the first derivative of maximum reaction velocity (|min1|), the second derivative of maximum acceleration (|min2|), and maximum deceleration (|max2|) were investigated. Patients were classified based on the duration of APTT prolongation into mild (33 s53 s) groups. A comparison of APTT seconds and CWA parameters |min1|, |min2|, and |max2| was conducted for HA and LA-positive patients between each group. Furthermore, receiver operating characteristic (ROC) curves and area under the curve (AUC) were utilized to assess the diagnostic efficacy of CWA parameters and determine cut-off values. Results:The APTT results for HA and LA-positive patients were 70.2 s and 41.5 s, respectively, exhibiting a statistically significant difference ( P<0.001). CWA parameters |min1| were 1.459 %/s vs 3.868 %/s, |min2| were 0.124 %/s2 vs 0.502 %/s2, and |max2| were 0.054 %/s2 vs 0.388 %/s2in HA and LA patients, respectively ( P<0.001). In all APTT prolongation groups, the CWA parameters |min1|, |min2|and |max2| for HA were significantly lower than those for LA-positive patients ( P<0.05). CWA graph analysis revealed that the peak heights of |min1|, |min2|, and |max2| in HA were lower compared to LA patients. In the severe extension group, HA displayed significantly decreased peak values and a flatter, incomplete curve. ROC curve analysis indicated AUC values were greater than 0.8 ( P<0.01) for |min1|, |min2|, and |max2| in all APTT prolongation groups. Cut-off values for |min1|, |min2|, and |max2| were established for each prolongation group: mild (3.205 %/s, 0.423 %/s2, and 0.300 %/s2), moderate (2.884 %/s, 0.340 %/s2, 0.231 %/s2), and severe (2.209 %/s, 0.190 %/s2, 0.095 %/s2). Conclusion:When APTT was extended within the same range, there were significant differences in CWA parameters between HA patients and LA patients, ROC curve analysis demonstrated the effectiveness of CWA parameters in distinguishing HA from LA-positive patients,APTT-CWA can serve as a low-cost, efficient, and specific method for the rapid identification of hemophilia and lupus anticoagulant-positive patients.
