OBJECTIVE To understand the development status and existing problems of traditional Chinese medicine（TCM） pharmacists in public TCM hospitals in China， aiming to provide suggestions for the competent departments to formulate management policies for TCM pharmacists and promote the healthy development of TCM. METHODS The data on the number and professional titles of TCM pharmacists in public TCM hospitals in China from 2019 to 2023 were collected. Descriptive analysis was employed to analyze the number， distribution and professional titles of TCM pharmacists in public TCM hospitals across the country， and to measure the quantity shortfalls of the number of TCM pharmacists in these hospitals. RESULTS From 2019 to 2023， the number of TCM pharmacists in public TCM hospitals in China grew slowly， with an average annual growth rate of 2.56%. However， the proportion of TCM pharmacists to the total number of pharmacists in public TCM hospitals gradually decreased， with an average annual growth rate of －0.65%. In terms of hospital grades， the number of TCM pharmacists in tertiary public TCM hospitals showed positive growth， while those in secondary and primary public TCM hospitals showed negative growth. In terms of hospital types， the average annual growth rate of TCM pharmacists in TCM hospitals was 2.22%， in integrated Chinese and Western medicine hospitals it was 7.97%， and in ethnic minority medicine hospitals it was 2.74%. The development of TCM pharmacists in different provinces was uneven. The annual growth rate of TCM pharmacists in Guizhou exceeded 10%， while the growth rate in Hunan and Heilongjiang was negative. In 2023， the number of TCM pharmacists per thousand population in public TCM hospitals was 0.03， indicating a relatively low staffing level. The professional titles of TCM pharmacists in public TCM hospitals were mainly primary and E-mail：601907549@qq.com intermediate， with a total of 67.33%. According to the calculation that the proportion of TCM pharmacists to pharmacists was not less than 60%， public TCM hospitals and hospitals of integrated TCM and Western medicine should be reconfigured with TCM pharmacists 6 212 and 1 288 people， respectively. CONCLUSIONS The number of TCM pharmacists in public TCM hospitals is growing slowly， with insufficient staffing levels， relatively low professional titles， and uneven distribution and development across provinces. It is suggested that relevant competent departments strengthen policy guidance， increase the attention given by the state level to TCM pharmacists， strengthen the construction of the talent team for TCM pharmacists， improve the quality and optimize the allocation of TCM pharmacist talents in order to promote the high-quality development of TCM services.

OBJECTIVES: To investigate the impact of hepatitis B virus (HBV) infection on oral microbiota and metabolites in patients with metabolic dysfunction-associated fatty liver disease (MAFLD) and the underlying mechanisms. METHODS: This prospective study was conducted in 47 MAFLD patients complicated with chronic hepatitis B (CHB) and 48 MAFLD patients without CHB enrolled from November, 2023 to January, 2024. Fasting tongue coating samples were collected from the patients for analyzing microbial community structures and metabolites using high-throughput 16S rDNA sequencing and non-targeted metabolomics techniques, and their associations with clinical indicators and biological pathways were explored using correlation analysis and functional annotation. RESULTS: The levels of fasting blood glucose, total cholesterol (TC), gamma-glutamyl transferase (GGT), and severity of fatty liver were all significantly lower in MAFLD+CHB group than in MAFLD group. Microbiota analysis showed that the abundances of Patescibacteria (at the phylum level), Hydrogenophaga, and Absconditabacteriales (at the genus level) were significantly increased, while the abundance of Megasphaera was decreased in MAFLD+CHB group. The differential microbiota were significantly correlated with TC, GGT and low-density lipoprotein (r=-0.68‒0.75). Metabolomics analysis revealed that 469 metabolites (including lipids and amino acids) were upregulated and 2306 (including organic oxygen-containing compounds and phenylpropanoids) were downregulated in MAFLD+CHB group, for which KEGG enrichment analysis suggested abnormal activation of the linoleic acid metabolism and glycerophospholipid metabolism pathways. Correlation analysis between microbiota and metabolites indicated that Patescibacteria and Megasphaera, which were positively correlated with lipid metabolites and negatively with fatty acid metabolites, respectively, jointly affected glycolipid metabolism and oxidative stress pathways. CONCLUSIONS Compared to patients with MAFLD alone, MAFLD patients with concurrent chronic HBV infection showed lower levels in some lipid metabolism indicators and the degree of hepatic steatosis, accompanied by alterations in oral microbiota structure and metabolic profiles. The precise mechanisms involved require further investigation to be fully elucidated.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

Objective:To preliminarily evaluate the effects and analyze the influencing factors of continuous renal replacement therapy (CRRT) in severe burn patients complicated with acute kidney injury (AKI).Methods:This study was a retrospective case series study. From January 2010 to December 2020, 79 severe burn patients complicated with AKI who received CRRT and met the inclusion criteria were admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University). The general data (the same below) of all patients were collected, including gender, age, body mass index, burn area, burn index, cause of injury, whether combined with inhalation injury, acute physiology and chronic health status evaluation Ⅱ (APACHE Ⅱ) score and sepsis-related organ failure assessment (SOFA) score on admission, admission time after burn, and time of AKI after admission. The total efficacy of CRRT, including overall effective rate, complete effective rate, partial effective rate, ineffective rate, and deterioration rate, creatinine, urea, cystatin C, and fluid overload rate before and after treatment, in-hospital mortality, predictive mortality based on Baux scoring model, the most common cause of death, and length of hospital stay were recorded. According to the effect of CRRT, the patients were divided into effective group (42 patients) and ineffective group (37 patients). The general information of patients, the time to initiate CRRT after the occurrence of AKI, the duration of CRRT, etiology of AKI, AKI stage before CRRT initiation, CRRT mode, anticoagulant type, and in-hospital mortality were compared between the two groups of patients. The independent influencing factors for CRRT in severe burn patients complicated with AKI were screened. According to the etiology of AKI, the patients were divided into prerenal group (22 patients) and renal group (57 patients). The general information of patients, the time to initiate CRRT after the occurrence of AKI, the duration of CRRT, and total efficacy of CRRT (except for the most common cause of death) were compared between the two groups of patients.Results:Among the 79 patients, 73 cases were male and 6 cases were female, with age of (46±14) years, body mass index of (24.0±2.9) kg/m 2, total burn area of (69±26)% total body surface area (TBSA), full-thickness burn area of (44±25)%TBSA, and burn index of 57 (36, 76). There were 36 cases of flame burns, 19 cases of electrical burns, 16 cases of hydrothermal burns, 6 cases of explosive burns, and 2 cases of chemical burns. Thirty-nine patients were complicated with inhalation injury. The APACHE Ⅱ score was 16 (12, 18) and the SOFA score was 11 (5, 13) on admission. The patients were admitted to the hospital on 0 (0, 2) d after burn, and AKI occurred on 0 (0, 6) d after admission. The overall effective rate of CRRT was 53.16% (42/79), the complete effective rate was 30.38% (24/79), the partial effective rate was 22.78% (18/79), the ineffective rate was 31.65% (25/79), and the deterioration rate was 15.19% (12/79). The creatinine and urea of patients after treatment were significantly lower than those before treatment (with Z values of -3.26 and -2.54, respectively, P<0.05); there were no statistically significant differences in the cystatin C and fluid overload rate of patients before and after treatment ( P>0.05). The in-hospital mortality of patients was 17.72% (14/79), and the predictive mortality based on Baux scoring model was 75.10% (18.94%, 91.84%). The most common cause of death was multiple organ failure, and the length of hospital stay was 39.43 (11.52, 110.58) d. There were statistically significant differences in the full-thickness burn area, the duration of CRRT, and etiology of AKI of patients between effective group and ineffective group (with Z values of -1.99 and -2.90, respectively, χ2=5.58, P<0.05). There were no statistically significant differences in the other indicators ( P>0.05). The etiology of AKI and full-thickness burn area were the independent influencing factors for CRRT in severe burn patients complicated with AKI (with odds ratios of 4.21 and 1.03, respectively, 95% confidence intervals of 1.20-14.80 and 1.00-1.05, respectively, P<0.05). There were statistically significant differences in the cause of injury, overall effective rate of CRRT, total burn area, burn index, admission time after burn, time of AKI after admission, the time to initiate CRRT after the occurrence of AKI, and predictive mortality based on Baux score model of patients between prerenal group and renal group (with χ2 values of 12.59 and 5.58, respectively, Z values of 2.46, 2.43, -2.43, -4.03, -3.01, and -2.31, respectively, P<0.05). Before treatment, urea and cystatin C of patients in renal group were significantly higher than those in prerenal group (with Z values of -2.98 and -2.77, respectively, P<0.05), and the liquid overload rate was significantly lower than that in prerenal group ( Z=-2.99, P<0.05); after treatment, the cystatin C of patients in renal group was significantly higher than that in prerenal group ( Z=-2.08, P<0.05); there were no statistically significant differences in the other indicators ( P>0.05). Conclusions:CRRT can significantly improve renal function, avoid fluid overload, and alleviate renal injury in severe burn patients complicated with AKI. Prerenal AKI is the main independent influencing factor leading to ineffective CRRT.

Objective To explore the correlation between the expression of long non-coding RNA(lncRNA)brain ischemia-related factor(BIRF)and focally amplified lncRNA on chromosome 1(lncRNA FAL1)in serum and the degree of white matter lesions(WML)in patients with cerebral small vessel disease(CSVD).Methods From June 2021 to June 2023,102 CSVD patients admitted to Affiliated Hospital of Chengde Medical University were collected,and these patients were grouped into WML group(n=72)and non WML group(n=30)based on WML diagnostic criteria.According to the Fazekas score,the WML group was further grouped into mild WML group(n=24),moderate WML group(n=36)and severe WML group(n=12).Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)was applied to detect the levels of lncRNA BIRF and lncRNA FAL1 in serum.Pearson correlation was applied to analyze the correlation between serum lncRNA BIRF and lncRNA FAL1 levels.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum lncRNA BIRF and lncRNA FAL1 levels for severe WML in CSVD patients.Results The age(70.50±5.86 years),history of hypertension(Yes/No,43/29),history of diabetes(Yes/No,45/27),IL-33(68.35±6.80 pg/ml),IL-18(97.78±9.65 ng/L),ubiquitin carboxyl terminal hydrolase L1(UCH-L1)(0.29±0.10 μg/L)and lncRNA BIRF level(2.45±0.30)of patients in the WML group were higher than those in the non WML group(67.10±5.76 years,11/19,9/21,62.48±6.13 pg/ml,92.56±9.37 ng/L,0.24±0.06 μg/L,1.02±0.11),while the expression of serum lncRNA FAL1(0.52±0.10)was lower than that in the non WML group(1.04±0.15),with significant differences(t=2.683,4.518,8.978,4.085,2.510,2.550,25.346,20.500,all P<0.05).The serum lncRNA BIRF levels of CSVD patients in the mild,moderate and severe WML groups(2.23±0.23,2.47±0.31,2.82±0.42)were increased sequentially,while the expression of serum lncRNA FAL1(0.60±0.15,0.51±0.09,0.40±0.04)was decreased sequentially,with significant differences(F=14.913,13.899,all P<0.05).Pearson correlation analysis,the serum levels of lncRNA BIRF and lncRNA FAL1 in patients with WML were negatively correlated(r=-0.603,P<0.001),serum lncRNA BIRF was positively correlated with Fazekas score in WML patients(r=0.483,P<0.001),but serum lncRNA FAL1 was negatively correlated with Fazekas score(r=-0.507,P<0.001).The AUCs of serum lncRNA BIRF and lncRNA FAL1 levels alone and both combination for predicting severe WML in CSVD patients were 0.756(0.641～0.850),0.839(0.733～0.915)and 0.892(0.796～0.953),respectively,and the combination of the two was superior to the detection of serum lncRNA BIRF alone(Z=2.111,P=0.035).Conclusion The serum lncRNA BIRF level is increased and lncRNA FAL1 is reduced in patients with CSVD and WML,and both are related to the degree of WML in CSVD patients.

Objective:To explore the clinical application and effect of FilmArray ? meningitis/encephalitis (ME) panel in identifying pathogens of central nervous system (CNS) infections in children. Methods:Molecular biology study.Cerebrospinal fluid (CSF) samples were prospectively obtained through lumbar puncture from children with suspected CNS infections admitted to the Department of Infectious Diseases at Beijing Children′s Hospital, Capital Medical University from May to November 2019.These samples were subjected to both routine clinical pathogen testing and FilmArray ME panel testing.Polymerase chain reaction was used to validate all samples.Independent sample t-test or Mann-Whitney U-test was used for comparative analysis of the results and influence factors obtained by the two detection methods. Results:A total of 113 cases of suspected CNS infections were enrolled.Routine clinical testing yielded 17 cases, with a positive rate of 15.0%, including 4 positive CSF cultures, with a positivity rate of 3.5%.FilmArray ME panel detected 23 positive cases, with a positive rate of 20.4%.FilmArray ME panel detected bacteria in 7 cases, viruses in 13 cases, fungi in 1 case, and both viruses and bacteria in 2 cases.Among the common pathogens detected, FilmArray ME panel obtained the results on average 2.7 days in advance.Conclusions:Compared with CSF culture, FilmArray ME panel has the advantages of shorter detection period, higher positive detection rate, and higher virus detection rate.

Lattice strain ruthenium nanoparticles uniformly and stably supported on nitrogen-modified carbon nanosheets(RuNPs/NC)were prepared via simple wet-chemical and subsequent pyrolysis method.The nitrogen doped NC could effectively improve their uniform dispersion and lattice compression of RuNPs.Through changing the pyrolysis temperature,the nitrogen content,types and degree of lattice strain of RuNPs could be effectively tuned,which could be used to adjust and control their peroxidase-like activity.The as-prepared RuNPs/NC-900 exhibited highest peroxidase-like activity,and could catalyze the oxidation of 3,3′,5,5′-tetramethylbenzidine(TMB)to produce a blue product with the maximum absorption at 652 nm in the presence of H2O2.The steady-state kinetic analysis indicated that the reaction catalyzed by RuNPs/NC followed the Michaelis-Menten kinetic model.Tannic acid(TA),gallic acid(GA)and ascorbic acid(AA)could effectively inhibit the RuNPs/NC-H2O2-triggered chromogenic reaction of TMB,resulting in color fading and decrease in absorbance.Based on this,a sensitive and accurate system was constructed for detection of TA,GA and AA.The detection limits(3σ/S)for TA,GA and AA were 0.014,0.014 and 0.29 μmol/L,respectively.This study not only developed a colorimetric sensing method based on RuNPs/NC nanozyme but also offered a new approach for the sensitive detection of antioxidants in food.

Objective To explore the mechanism of Buyang Huanwu Decoction for"treating different diseases with same therapies"in type 2 diabetes mellitus(T2DM)and Alzheimer's disease(AD)based on network pharmacology and molecular docking techniques.Methods Firstly,the active ingredients of seven herbs in Buyang Huanwu Decoction were searched and screened by TCMSP,SymMap and other databases,the target prediction of these active ingredients was carried out by PharmMapper.The disease targets of T2DM and AD were collected from OMIM,DrugBank,GeneCards and Disgenet databases.The potential targets of Buyang Huanwu Decoction for"treating different diseases with same therapies"in T2DM and AD were obtained by intersecting with targets of active ingredients and the disease targets.Then STRING database and Cytoscape software were used to construct the PPI network and"herbs-components-targets"network,respectively.The core targets and pharmacodynamic components were screened through network topology analysis.Furthermore,GO functional and KEGG enrichment analysis was performed for potential targets using Metascape database.Finally,AutoDock software was used to verify the molecular docking between the selected components and targets.Results Ninety-four active components of Buyang Huanwu Decoction can act on 342 protein targets,and 100 intersection targets were obtained by comparing with 3 140 AD targets and 1 708 T2DM targets.GO functional enrichment analysis showed that these targets were mainly involved in MAPK cascade-mediated regulation,hormone-mediated signaling pathways,cellular response to lipids,regulation of inflammation response and other biological processes.MAPK,PI3K/Akt,FoxO,AGE/RAGE,insulin resistance,lipid and atherosclerosis,and non-alcoholic fatty liver signaling pathway were significantly enriched in KEGG analysis.PPI and topology analysis of"herbs-components-targets"network were used to screen out 10 core targets such as MAPK8,MAPK14,GSK3B,PPARG,and 10 core pharmacodynamic components such as paeoniflorin,benzoyl paeoniflorin,(+)-catechin.The results of molecular docking showed that these components had strong binding ability to the targets.Conclusion The core components of Buyang Huanwu Decoction,such as paeoniflorin and catechin,may act on PPARG,GSK3B and other key targets,and participate in the regulation of signaling pathways including MAPK and PI3K/Akt,which play a role in"treating different diseases with the same therapies"of T2DM and AD.

Objective To develop and validate a risk prediction model based on early platelet-related parameters for bronchopulmonary dysplasia(BPD)in neonates admitted to the neonatal intensive care unit(NICU),and to facilitate early identification and intervention in high-risk populations.Methods Clinical data of 291 preterm infants with a gestational age(GA)≤32 weeks or a birth weight(BW)＜1 500 g,admitted to the NICU,were retrospectively analyzed.Out of these,214 cases were selected as the modeling group.This group was further categorized into the BPD group(n=76)and the non-BPD group(n=138),based on whether they required oxygen therapy at 28 days post-birth.Perinatal data,platelet-related parameters and other indicators between the two groups.Univariate and multivariate Logistic regression analyses were conducted to identify BPD risk factors,followed by the construction of a nomogram.An additional cohort of 105 preterm infants with GA≤32 weeks or BW＜1 500 g,were used to validate the model.This cohort was divided into the BPD group(n=43)and the non-BPD(n=62)group.Receiver operating characteristic(ROC)curve and calibration curve were used to internally verify the efficiency of the prediction model.Results The Logistic regression analysis identified GA,BW,Apgar score at 5 minutes≤7,invasive ventilation,platelet count(PLT)and mean platelet volume(MPV)as significant factors in the model(P＜0.05).The constructed nomogram was formulated using R language,and the areas under the ROC curve(AUC)for the three models were 0.908,0.931 and 0.918,respectively(P＜0.05).The verification group was verified by Bootstrap.The calibration curve showed a good fit.The internal validation AUC values of the three models were 0.877,0.890 and 0.886,respectively.Conclusion GA,BW,invasive ventilation,Apgar score at 5 minutes≤7,MPV and PLT are key risk factors for BPD onset.The risk prediction model based on these indicators can effectively predict BPD,providing clinicians with a valuable tool for early detection and intervention in the development of BPD.
