BackgroundCognitive function is closely related to an individual's quality of life and social functioning， with approximately 20%~35% of patients with depressive disorder experiencing some degree of cognitive impairment even after clinical symptom remission. Existing evidence suggests that tACS can improve specific cognitive domains， such as memory function， while its effects on other cognitive dimensions， such as executive functioning， attention， and information processing speed， remain unclear. ObjectiveTo explore the effects of tACS on the multidimensional cognitive functions and emotional problems of patients with depressive disorder， thus to provide references for the treatment of depressive disorder. MethodsForty-nine patients with depressive disorder who were hospitalized in the Fourth People's Hospital of Wuhu from November 2022 to October 2024 and met the diagnostic criteria for depressive disorder outlined in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， were selected as study participants. Subjects were randomly divided into study group （n=23） and control group （n=26） based on Microsoft Excel. Both groups received sertraline treatment. The initial dose was 50 mg/day， which gradually titrated upward based on individual variability， drug tolerance， and therapeutic response， with a maintenance dose ranging from 100 to 200 mg/day. In addition， the study group underwent tACS therapy for 4 weeks， with 5 sessions per week， each lasting 20 minutes. The control group received sham stimulation， in which the stimulus was interrupted after the first 30 seconds. At baseline， the 4^th week， and the 12^th week of treatment， patients were assessed using the Hamilton Depression Scale-17 item （HAMD-17）， Hamilton Anxiety Scale （HAMA）， and MATRICS Consensus Cognitive Battery （MCCB）. ResultsRepeated measures analysis of variance indicated that both the time effect and the time×group interaction effect for HAMD-17 scores were statistically significant between the two groups （F=260.437， 25.309， P<0.01）. At week 12 of treatment， the HAMD-17 score in the study group was lower than that in the control group （t=4.236， P<0.01）. For HAMA scores， the time effect， group effect， and time×group interaction effect were all statistically significant between the two groups （F=248.082， 4.506， 9.500， P<0.05 or 0.01）. At weeks 4 and 12， study group reported lower HAMA scores compared with control group （t=4.580， 2.608， P<0.05 or 0.01）. Regarding the MCCB scores for attention/vigilance， verbal learning， and overall composite， the time effect， group effect， and time×group interaction effect were all statistically significant between the two groups （F=70.331， 27.882， 51.679， 5.560， 10.948， 7.860， 8.490， 3.874， 5.025， P<0.05 or 0.01）. After intervention， the study group showed significantly higher MCCB scores for attention/vigilance， verbal learning， and overall composite at both week 4 （t=-2.149， -3.530， -2.740， P<0.05） and week 12 （t=-3.534， -3.576， -3.838， P<0.01） when compared to the control group. ConclusionThe combined tACS and sertraline therapy may demonstrate superior efficacy to pharmacotherapy alone in the short term for improving attention/vigilance， verbal learning， overall cognitive function， and anxiety symptoms in patients with depressive disorders. Based on the 12-week outcomes， the combined tACS and sertraline therapy not only sustaine its previously observed advantages in improving cognitive domains and anxiety symptoms， but also demonstrate potentially superior efficacy over monotherapy in alleviating depressive symptoms. ［Fund by Clinical Medical Research Transformation Special Project of Anhui Province （number， 202204295107020065）］

Objective To investigate the influence and predictive value of systemic immune inflammation(SII),fibrinogen(Fib)and triglyceride glucose index(TyG)on the risk of diabetic kidney disease(DKD).Methods A total of 1073 patients with type 2 diabetes mellitus(T2DM)admitted to The Endocrinology Department of Hebei Yiling Hospital Affiliated to Hebei Medical University were enrolled in this study from January 2020 to December 2022.All the patients were divided into two groups according to the urinary protein creatinine ratio:DKD group(UACR≥30 mg/g,DKD,n=412)and simple T2DM group(UACR<30 mg/g,T2DM,n=661).Pearson correlation analysis was used to evaluat the correlation between SII,TyG,Fib and other indicators.Multiple logistic regression analysis was used to find the influencing factors for DKD.The clinical value of Fib,SII,TyG,and combined indicators in diagnosing DKD was tested by receiver operating characteristic(ROC)curve analysis.Results Compared with T2DM group,age,duration of DM,FPG,TG,TyG,cystatin C(CysC),glutamyl transpeptidase,SUA,homocysteine,SII,neutrophil count,Fib and D-D were increased(P＜0.05 or P＜0.01),while albumin(ALB)and HDL-C were decreased(P＜0.05 or P＜0.01)in DKD group.Pearson correlation analysis showed that SII was positively correlated with CysC,Scr,SUA,Fib,FDP,and D-D(P＜0.05 or P＜0.01),and negatively correlated with eGFR,ALB(P＜0.01);TyG is positively correlated with SUA(P＜0.01);Fib is positively correlated with CysC,Scr(P＜0.01),and negatively correlated with eGFR(P＜0.01).Multiple logistic regression analysis showed that TyG and Fib were the influencing factors for DKD.The ROC curve analysis showed that the area under the ROC curve for the combined index was 0.679,with a specificity of 74.2%,a sensitivity of 53.5%,and an optimal cutoff value of 0.276.Conclusion SII and Fib can directly cause renal function damage in DKD,while IR promotes DKD progression through metabolic disorders.The combined predictive value of Fib,SII,and TyG for DKD risk is superior to a single indicator.

Objective To quantitatively assess the influence of various factors on the pharmacokinetic parameters of propofol and to develop a propofol population pharmacokinetic model tailored for Chinese patients.Methods Thirty patients scheduled for selective abdominal surgeries received an anesthesia dose of propofol at 2.0 mg·kg-1.The concentration of propofol in collected venous blood samples was measured using liquid chromatography-tandem mass spectrometry.Polymorphisms in metabolizing enzyme genes were detected through Sanger sequencing technology.Pharmacokinetic parameters were computed,and models were constructed and evaluated using Phoenix Winnonlin software.Results Through software analysis,the drug's in vivo process was best described by a three-compartment model.The population mean values for the central compartment clearance rate(CL),shallow peripheral compartment clearance rate(Q2),deep peripheral compartment clearance rate(Q3),central compartment volume of distribution(V),shallow peripheral compartment volume of distribution(V2),and deep peripheral compartment volume of distribution(V3)were 1.71 L·min-1,1.31 L·min-1,1.51 L·min-1,5.92 L,19.86 L and 99.06 L,respectively.Body weight was identified as a significant covariate affecting CL and V,and was incorporated into the model.Conclusion The evaluation of the final model demonstrates its substantial predictive capability,offering directional guidance for the clinical administration of propofol.

Objective:To investigate the vaccination status, characteristics and prognosis of patients suffering from a combination of COVID-19 and chronic lymphocytic anemia (CLL) in China.Methods:Clinical data of 328 patients with chronic lymphocytic leukemia (CLL) who were first diagnosed with COVID-19 and treated in the Department of Hematology of Jiangsu Provincial People’s Hospital between November 2022 and February 2023 were retrospectively analyzed. Univariate and multivariate analysis of data of patients with severe/critical COVID-19 were conducted by applying the binary logistic regression model.Results:The median age of the CLL patients was 60 (24-87) years. 23.5% (77/328) of these patients suffered from severe/critical COVID-19 infection. Univariate analysis of the data demonstrated that a combination of factors including age >67 years ( OR=2.15, 95% CI 1.24- 3.73, P=0.006), diabetes ( OR=2.09, 95% CI 1.05-4.20, P=0.037), chronic hepatitis B ( OR=2.91, 95% CI 1.30-6.51, P=0.010), CLL progressive ( OR=3.79, 95% CI 1.57-9.15, P=0.003) and CD20 antibody-based treatments within three months prior to the COVID-19 infection ( OR=2.79, 95% CI 1.35-5.77, P=0.006) were the risk factors for severe/critical COVID-19. According to the multivariate analysis, CLL progressive ( OR=2.98, 95% CI 1.10-8.10, P=0.033) was an independent risk factor for severe/critical COVID-19 and administration of the BTK (Bruton tyrosine kinase) inhibitor monotherapy might exert a protective effect and influence a positive outcome of the COVID-19 infection ( OR=0.38, 95% CI 0.16-0.90, P=0.028). Among the 242 patients who were followed up until October 2023, 9.1% (22/242) had multiple subsequent COVID-19 infections (≥3), and 2.1% (5/242) had persistent COVID-19 infections (patients with persistent positive test for the SARS-CoV-2 antigen testing until missing follow-up for any reason). The peak value of the anti-SARS-CoV-2-IgG titres was observed between three and four months post symptom onset (median: 3.511 S/CO vs 1.047 S/CO, P<0.05). The levels of immunoglobulin A gradually decreased following infection with COVID-19, and its trough levels were attained between two to four weeks post infection (median: 0.30 g/L vs 0.74 g/L, P<0.05). According to this study the mortality of patients suffering from a combination of COVID-19 infection and CLL was 2.7% (9/328), and the main reason for their death was respiratory failure and heart failure. Conclusions:A low rate of COVID-19 vaccination and a high rate of severe/critical COVID-19 infection was observed in the CLL patients. CLL progressive was associated with severe/critical COVID-19. Anti-CD20-based treatments received within the past three months might be a risk factor for exacerbation of COVID-19 infection, whereas a monotherapy with BTK inhibitors exert a protective effect and improve outcome of COVID-19 infection.

Based on the problem of disconnection between "teaching" and "need" in the occupational education of nuclear emergency medical rescue in the past, this study proposes the curriculum goal of "the combination of three abilities" and performs the optimization and practice of the occupational education curriculum system of nuclear emergency medical rescue from the aspects of curriculum setting, curriculum content, teaching methods, and assessment and evaluation. The results show that the new curriculum system can significantly improve the comprehensive ability of nuclear emergency medical rescue among trainees and better meet the requirements for their posts, thereby playing an important role in cultivating high-quality military medical talents in nuclear emergency medical rescue.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

An etiological analysis of a diarrhea outbreak attributed to C.perfringens was conducted.Anal swab and envi-ronmental smear samples were collected and subjected to fluorescence PCR detection of C.perfringens plc and cpe,as well as isolation and culture of C.perfringens before and after enrichment culture.The isolated colonies underwent fully automated bi-ochemical identification and time-of-flight mass spectrometry analysis.Whole genome sequencing of isolates identified as C.perfringens was performed to analyze the strain carrying virulence and resistance genes,and the genetic aggregation based on single nucleotide polymorphisms in the core genome for all isolates.The positivity rates for plc and cpe genes without bacterial enhancement were 46.15％(6/13)and 53.85％(7/13),respectively.The positivity rates for plc and cpe genes after 24 h anae-robic bacterial enhancement in BHI were 38.46％(5/13)and 53.85％(7/13).All ten isolated CP belonged to the F biotype,with virulence gene characteristics of plc+/cpb-/etx-/iA-/cpe+/cpb2+/netB-.The phylogenomic tree indicated that all ten case-patient isolates except P1 isolate(lineage 1)were closely related and clustered together in a single clade(lineage 2).Lineage 1 belonged to ST589 and carried the macrolide re-sistance gene erm(Q),whereas lineage 2 belonged to ST149 and carried the tetracycline resistance gene tetB(P).The outbreak was caused by type F C.perfringens,and most ca-ses were infected with a group of highly clonogenic cpe+col-onies.Whole genome sequencing technology can be applied to etiology analysis of C.perfringens outbreak events,and the enrichment culture and molecular screening methods for C.per-fringens based on anal swab samples should be further developed and applied.

Objective:To study the molecular mechanism of functional defect of protein C (PC) caused by point mutations of human protein C gene (PROC) N355S,G392E and T314A. Methods:The wild-type and mutant plasmids (PCWT,PCN355S,PCG392E,PCT314A) of PROC gene were constructed and transiently transfected into HEK293 cells. The expression of mutant proteins in vitro were tested. The mRNA level changes of wild-type and mutant PC after 24 h of transfection were detected by real-time PCR. Western blot and ELISA were used to detect the changes of intracellular and extracellular protein levels of wild-type and mutant PC. The supernatant of cells transfected for 24-48 h was concentrated by ultrafiltration. The protein in the concentrated solution was quantified,and PC activation and enzyme kinetics tests were performed. Clustal Omega multiple sequence alignment was used to analyze the conservation of amino acid mutation sites. The effect of mutation on PC protein structure was analyzed by PyMOL software. Results:The relative expression abundances of PROC mRNA in PCN355S,PCG392E and PCT314A groups were 1.14±0.46,0.96±0.08 and 1.08±0.17,respectively,and there were no significant differences compared with 1.02±0.24 in PCWT group (P>0.05). Western blot analysis of the lysates of transfected cells showed that the content of PCT314A recombinant protein slightly decreased and the band became relatively lighter. The ELISA results of the concentrated cell culture supernatants showed that the PC:Ag levels of PCN355S and PCG392E were 98.8％±2.4％ and 101.4％±3.1％,respectively,with no significant differences compared with PCWT,while PCT314A decreased compared with PCWT (PC:Ag:88.6％±3.2％) (P<0.05). The results of enzyme kinetics test showed that APCN355S (Km=338.3±43.2,Vmax=2.015±0.12),APCG392E (Km=292.2±28.4,Vmax=1.893±0.07) and APCT314A (Km=299.5±24.6,Vmax=1.775±0.06) showed an increase in Km and a decrease in Vmax compared with APCWT (Km=238.2±4.58,Vmax=3.205±0.06). Multiple sequence alignment suggested that the three mutations be highly conservative in different species. The structural model suggested that the amino acid substitutions of N355S,G392E and T314A mutations collide with the surrounding amino acid groups,causing distortion of the surrounding structure,which may have adverse effects on the folding and biological function of PC. Conclusion:The N355S,G392E and T314A mutations in the PROC gene cause functional defects in PC by weakening the binding between PC and substrate. These three mutations have caused serious spatial collisions in the protein structure,affecting the folding of PC and the reactivity of active sites.

Aim To clarify the differential proteins of mammary tissues in Xihuang pills(XHP)against hy-perplasia of mammary glands(HMG)based on quanti-tative proteomics technology and validate them,and to explore the mechanism of action.Methods SD rats were randomly divided into blank group,model group and XHP group,with 10 rats in each group.Except for the blank group,estrogen and progesterone were injec-ted intramuscularly to establish a rat model of mamma-ry hyperplasia for 30 d.After XHP was administered for 14 d,the rats in each group were observed to have morphological changes in the apparent morphology of the mammary tissues,and pathological changes in the mammary tissues were stained with hematoxylin-eosin staining(HE),and the differentially expressed pro-teins(DEPs)in the groups were screened by quantita-tive proteomics technology and subjected to bioinforma-tics analysis,and Western blot to verify the key DEPs.Results Compared with the model group,the appar-ent pathological morphology of the XHP group was sig-nificantly improved,the diameter of the nipple height of the rats was significantly reduced(P＜0.01),and the degree of histopathology was significantly allevia-ted.Quantitative proteomics identified 4,299 DEPs in mammary tissue,and bioinformatics analysis of 14 DEPs with consistent changes between the XHP group and the blank group relative to the model group re-vealed that they were related to the regulation of mus-cular systemic processes,regulation of muscle contrac-tion,DNA replication,and pre-initiation of DNA repli-cation.Western blot results showed that,compared with the model group,rat mammary tissue of the XHP group showed significantly lower levels of ACLY and ALDOC protein expression levels were significantly re-duced and BIN1 protein expression levels were signifi-cantly increased(P＜0.01).Conclusions XHP may exert its anti-mammary hyperplasia effect through the regulation of BIN1,ACLY and ALDOC protein lev-els,the regulation of DNA replication,the regulation of pre-initiation of DNA replication and muscular sys-temic processes,and the regulation of muscle contrac-tion.
