OBJECTIVE To investigate the immunotoxicity and potential mechanism of Carthamus tinctorius extract on RBL-2H3 cells via direct induction and induction by sensitized serum prepared with an overdose of the extract. METHODS For direct induction by C. tinctorius extract， RBL-2H3 cells were divided into normal control group （no treatment） and C. tinctorius extract group （10 mg/mL）. For induction by sensitized serum prepared with an overdose of C. tinctorius extract， rats were divided into normal control group （no treatment）， adjuvant-treated group （1 mL adjuvant）， C. tinctorius extract-induced sensitization group （2.04 g/mL）， and ovalbumin （OVA）-induced sensitization group （50 mg/mL）. Sensitization was performed once every other day for a total of 3 times. Morphological changes of RBL-2H3 cells were observed， the degranulated rate of cells was counted， and histamine content was determined； the release rate of β -hexosaminidase （ β -Hex） was calculated， the levels of interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） and intracellular Ca²⁺ concentration were detected. RESULTS Under direct induction by C. tinctorius extract， compared with the normal control group， the volume of cells in the C. tinctorius extract group was significantly reduced and cell density decreased； the degranulation rate of cells， histamine content， β -Hex release rate， IL-6 and TNF-α levels， as well as intracellular Ca²⁺ concentration were all significantly increased （ P ＜0.01）. Under i nduction by sensitized serum prepared with an overdose of C. tinctorius extract， compared with the adjuvant-treated group， the above indicators in the C. tinctorius extract-induced sensitization group and the OVA-induced sensitization group showed consistent changes with those in the C. tinctorius extract group under direct induction， all being significantly elevated （ P ＜0.01）. CONCLUSIONS C. tinctorius extract may affect degranulation of RBL-2H3 cells and promote Ca²⁺ influx accompanied by the release of pro-inflammatory cytokines through two approaches： direct induction and induction by sensitized serum prepared under overdose administration. Its mechanism may be related to the activation of the calcium signaling pathway and the regulation of inflammatory pathways under the synergistic effect of multiple components.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

ObjectiveTo investigate the inhibitory effect of Biejiajian Pills （BJJW） on the growth of liver cancer， as well as its potential mechanism in mediating the AMP-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group， BJJW group （2.2 g/kg）， and metformin group （250 mg/kg）， and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment； HE staining was used to observe histopathological changes； the levels of reactive oxygen species （ROS） and adenosine triphosphate （ATP） in tumor tissue were measured； immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Tukey’s test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group， the BJJW group had a tumor inhibition rate of 45.73%， with significant reductions in both tumor volume and weight （P<0.01）. Pathological examination showed that compared with the model group， the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group， the BJJW group had a significant increase in ROS level （P<0.001） and a significant reduction in ATP level （P<0.001）， as well as significant increases in p-AMPK/AMPK ratio （0.81±0.20 vs 0.13±0.04， P<0.01） and p-ULK1/ULK1 ratio （0.69±0.17 vs 0.18±0.13， P<0.01） and a significant reduction in p-mTOR/mTOR ratio （1.34±0.16 vs 3.20±0.62， P<0.01）. ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction， increasing the level of ROS， reducing the level of ATP， and activating the AMPK/mTOR signaling pathway.

Accurate characterization of the chemical composition of complex traditional Chinese medicine (TCM) is an essential foundation for the modern scientific interpretation of TCM principles. Mass spectrometry is the most dominant technique in current research on the material basis of TCM, offering the highest sensitivity and the richest information provision. Establishing mass spectrometry databases represents the most effective approach to facilitating the structural analysis of TCM chemical components. This paper systematically searches and reviews literature published from January 2005 to January 2025 through online databases such as China National Knowledge Infrastructure, PubMed, and Web of Science, using “mass spectrometry database” and “traditional Chinese medicine” as keywords. It reviews the current status of seven TCM chemical component mass spectrometry databases and seven natural product mass spectrometry databases. The key advancements of these mass spectrometry databases for natural products are summarized, detailing their characteristics, search methodologies, included information, and data sources. Additionally, challenges related to data quality, standardization, timely updates, database interaction, retrieval functionality, and data sharing and security are discussed in depth. Furthermore, the paper explores prospective development directions for TCM mass spectrometry databases, emphasizing the importance of open data sharing, technological innovation, and data security. Through this analysis, the paper aims to offer theoretical guidance and practical recommendations for the precise identification of TCM components, as well as for the construction and application of these databases.

Objective To analyze the mortality rate and trend of chronic obstructive pulmonary disease(COPD)among residents in Sichuan Province from 2011 to 2023.Methods The collected mortality monitoring data of residents from 2011 to 2023 were analyzed using Joinpoint regression the trend of COPD mortality rate in Sichuan Province from 2011 to 2023.Based on the COPD mortality rate data of residents from 2011 to 2023 to established an autoregressive integrated moving average method(ARIMA)to predict the trend of mortality rate changes.Results From 2011 to 2023,the crude mortality rate of males was 79.74/100,000,which was higher than that of females(64.82/105),and the standardized mortality rate of males(48.02/105)was higher than that of females(40.51/105)(P<0.05).From 2011 to 2023,the annual percentage change(APC)of male mortality rate and female mortality rate were-4.51% and-5.59%(P<0.05),and the APC of standardized mortality rate of male and female were-9.35%,and-9.91%,with a significant downward trend(P<0.05).From 2011 to 2023,the COPD mortality rates of residents aged 45～54,55～64,65～74 and≥75 years in Sichuan Province were-12.04%,-10.88%,-13.87% and-7.19%,respectively,and with an obvious downward trend in different age groups(P<0.05).The crude mortality rate of COPD in urban decreased from 100.67/105 to 52.93/105,and APC of the crude mortality rate was-5.71%;while the crude mortality rate of rural residents decreased from 86.13/105 to 60.10/105,and APC of the crude mortality rate was-3.69%,with an obvious downward trend(P<0.05%).The standardized COPD mortality rate of urban residents in Sichuan Province from 2011 to 2023 decreased from 79.13/105 to 24.09/105,and APC of the standardizedmortality rate was-10.09%;while the rural residents decreased from83.99/105 to 31.58/105,and APCwas-7.98%,with an obvious downward trend(P<0.05%).The ARIMA model was used to fit the COPD mortality rate in Sichuan Province in 2011～2023,and the COPD mortality rates in Sichuan Province in 2024～2028 were predicted to be 53.49/105,49.28/105,46.11/105,42.59/105 and 41.68/105,respectively.Conclusion The mortality rate of COPD among residents in Sichuan Province showed a downward trend from 2011 to 2023,with rural,male,and elderly populations being high-risk groups for COPD mortality.The ARIMA model had certain reference value for short-term prediction of COPD mortality rate.

Objective To compare differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects.Methods Kunming mice were randomly divided into eight groups,with 12 mice in each group consisting of equal numbers of males and females.These groups included a normal group,a model group,a positive group,a Angelica sinensis(AS)group,an Angelica sinensis water-soluble(AW)group,an Ethanol extract of Angelicae sinensis(AE)group,and an Angelica sinensis essential oil(AO)group.Except for the normal group,all other groups were established as blood deficiency constipation mouse models through subcutaneous injection of N-acetylphenylhydrazine combined with oral administration of loperamide hydrochloride.On the 7th day of modeling,each group received oral administration of the respective test substance once daily for three consecutive days.General condition and body weight changes of the mice were observed,peripheral blood cells were counted,stool morphology and fecal output were recorded,fecal moisture content and colonic tissue moisture content were determined,small intestine propulsion rate was assessed by a charcoal meal method,and serum levels of β-endorphin(β-EP),cholecystokinin octapeptide(CCK-8),substance P(SP),and vasoactive intestinal peptide(VIP)were determined by ELISA.Differences in the pharmacological activities of Angelica sinensis and its components on hematopoietic and laxative effects were analyzed.Results Compared with the normal group,model group mice showed significantly reduced white blood cell(WBC),red blood cell(RBC),hemoglobin(HGB),hematocrit(HCT),and platelet(PLT)counts,and body weight(P＜0.05 or P＜0.01).Additionally,fecal moisture content,colon moisture content,and small intestine propulsion rate were decreased(P＜0.05 or P＜0.01)and serum CCK-8 and SP levels were also lower(P＜0.01),while serum β-EP and VIP levels increased(P＜0.05).Compared with the model group,AS and AW groups had higher WBC,RBC,HGB,HCT,and PLT counts,defecation volume,fecal moisture content,and colon moisture content(P＜0.05 or P＜0.01).The AE group showed increased WBC,RBC,HGB,HCT,and PLT counts,and colon moisture content(P＜0.05 or P＜0.01),but defecation volume and fecal moisture content were not significantly altered.The AO group exhibited increased fecal moisture content,colon moisture content,and defecation volume(P＜0.05 or P＜0.01),but no significant changes in WBC,RBC,HGB,HCT,and PLT counts.The AE group showed no significant changes in defecation volume,fecal moisture content,and colon moisture content.The AS and AO groups had increased small intestine propulsion rates(P＜0.01),while there was no significant difference in small intestine propulsion rate between the AW and AE groups.The AS group had elevated serum CCK-8 and SP levels(P＜0.01)and decreased serum β-EP and VIP levels(P＜0.01).The AO group had increased serum CCK-8 and SP levels(P＜0.05),but no significant change in serum β-EP and VIP levels.The AW group had decreased serum VIP levels(P＜0.05),but no statistically significant difference in serum CCK-8 and SP levels.Compared with the AS group,the AW group had higher WBC,RBC,HGB,HCT,and PLT counts,while the AO and AE groups had lower levels of these parameters(P＜0.05).Both AW and AO groups had increased fecal moisture content(P＜0.05),and both AW and AE groups had increased colon moisture content(P＜0.05).AO,AE,and AW groups had elevated serum CCK-8 and SP levels and decreased serum β-EP and VIP levels(P＜0.05).In summary,the groups were ordered as follows:AE＞AO＞AS＞AW in terms of blood replenishment,AO＞AS＞AW＞AE in terms of promoting bowel movements,and AO＞AS＞AE＞AW in terms of intestinal motility.Conclusions Angelica sinensis and its components have varying degrees of blood replenishing and bowel-promoting activities.The AE component has strong blood replenishing activity,while the AO component has strong bowel-promoting and defecation-stimulating activity.These findings provide a reference for the development of traditional Chinese medicines based on Angelica sinensis components.

Objective:To investigate the clinicopathological and molecular genetic characteristics of diffuse gliomas with the features of polymorphous low-grade neuroepithelial tumor of the young (PLNTY) and their prognostic values.Methods:A retrospective analysis was performed on 14 cases of diffuse gliomas with PLNTY features diagnosed at the First Affiliated Hospital of Fujian Medical University, Fuzhou, China from June 2020 to August 2024. Their clinicopathological characteristics were examined, and their molecular genetic and epigenetic features were assessed using next-generation sequencing (NGS) and methylation analysis. Factors influencing prognosis were also analyzed.Results:Among the 14 patients, there were 8 males and 6 females, aged 3-62 years, median 29 (9, 50) years. All cases were initially diagnosed as low-grade diffuse gliomas histologically but exhibited the histological and immunohistochemical features of PLNTY. At the molecular level, all cases showed molecular abnormalities involving the mitogen-activated protein kinase pathway, including 5 cases with FGFR3-TACC3 (F3T3) fusion, 3 cases with FGFR2 fusion, 5 cases with BRAF V600E mutation, and 1 case with FGFR1 mutation. Among them, TERT promoter mutations were frequently observed in tumors with F3T3 fusion (5/5), while NCOR2 in-frame insertion mutations were prominent in tumors with non-F3T3 fusions. Clinical follow-up showed recurrence in 3 cases, all of which had F3T3 fusion and concurrent TERT promoter mutations. Prognostic analysis confirmed that F3T3 fusion with concurrent TERT promoter mutation was associated with poor prognosis.Conclusions:Diffuse gliomas with PLNTY features exhibit heterogeneity in clinicopathology and molecular genetics, with FGFR3/FGFR2 fusions and BRAF/FGFR1 mutations as the most common molecular alteration. They often have concurrent F3T3 fusion and TERT promoter mutations, which are related to poor prognosis. The possibility of molecular glioblastoma should be considered for these tumors. It is thus recommended to perform genetic testing on diffuse gliomas with PLNTY features in order to facilitate integrated diagnosis and provide molecular evidence for accurate evaluation of prognoses.

AIM:To evaluate the efficacy of inflix-imab in the maintenance of Perianal fstulizing Crohn's disease.METHODS:The clinical data of 24 patients with perianal fistula Crohn's disease(PFCD)treated with infliximab(IFX)in the Depart-ment of Anorectal Surgery of our hospital from No-vember 2020 to October 2023 were retrospectively collected.The clinical efficacy and safety were eval-uated by observing the clinical characteristics for 54 weeks.The fistula remission rate,clinical remis-sion rate,and endoscopic remission rate of pa-tients were calculated.The changes of laboratory indexes before and after treatment were recorded.Logistic regression was used to analyze the related factors of fistula remission.All adverse reactions oc-curred during IFX treatment were recorded.RE-SULTS:After 54 weeks of IFX treatment,the fistula remission rate,clinical remission rate,and endo-scopic remission rate were 37.5％,45.83％,and 33.33％,respectively.Fistula response at 14 weeks of treatment(OR=19.419,95％CI:1.267-297.559,P=0.033)was predictive factors for fistula remission at 54 weeks of treatment.The inflammatory index-es and nutritional indexes were significantly im-proved compared with those before treatment(P＜0.01).The scores of PDAI,CDAI and SES-CD were significantly different from those before treatment(P＜0.01).Five patients(20.83％)had adverse reac-tions,and the symptoms disappeared or improved after symptomatic treatment,and no patient had serious adverse reactions.CONCLUSION:IFX can ef-fectively promote the closure of PFCD fistula,im-prove the chronic inflammatory reaction of intesti-nal mucosa,alleviate clinical symptoms,and im-prove the quality of life of patients.IFX is effective and safe for PFCD maintenance treatment.

Objective To understand the current status and influencing factors of microbial contamination of dental unit waterlines(DUWLs)of secondary and lower medical institutions in Wuhan,and provide scientific basis for for-mulating prevention and control measures.Methods A stratified convenience sampling method was adopted to con-duct questionnaire survey on 248 dental medical institutions in 15 districts of Wuhan City,DUWLs from 44 medical institutions were sampled and detected according to hospital levels.Results Among disinfection and maintenance management measures for source water and waterlines,the highest implementation rate was the installation rate of anti-suction dental handpiece(73.39％,182/248),but only 16.48％(30/182)of institutions regularly conducted the detection on anti-suction function;The lowest was the daily disinfection rate of water storage tanks(17.53％,17/97).A total of 132 water specimens were collected from 44 medical institutions,with a qualified rate of microbi-al detection of 56.06％.The qualified rates for secondary,primary,and unclassified medical institutions were 77.78％,50.00％,and 50.72％,respectively,with statistically significant differences(P＜0.05).The qualified rates of microbial detection for source water,handpiece water,and three-way syringe water were 59.09％,50.00％,and 59.09％,respectively,with no statistically significant difference(P＞0.05).Univariate analysis re-sults showed that medical institutions that regularly conducted chemical disinfection on DUWLs,understood DU-WLs waterline cleaning and disinfection standards,regularly performed microbial monitoring on diagnosis and treat-ment water,qualified source water,and flushed waterlines for 3 minutes before and after daily consultations had a higher qualified rate of microbial detection in DUWLs diagnosis and treatment water,and the differences were all statistically significant(all P＜0.05).Conclusion The contamination status of DUWLs in secondary and lower medical institutions in Wuhan is relatively serious.It is recommended to focus on strengthening the training of rele-vant regulations,installing inlet filters,regularly detecting the anti-suction function of dental handpieces,imple-menting chemical disinfection and microbial monitoring on waterlines,standardizing the implementation of flushing before and after diagnosis and treatment,and strengthening the disinfection and use management of independent wa-ter storage tanks to control contamination.
