OBJECTIVE To compare the long-term cost-effectiveness of gonadotrophin-releasing hormone analogue （GnRHa） combined with recombinant human growth hormone （rhGH） （combination therapy regimen） versus GnRHa monotherapy （monotherapy regimen） in the treatment of central precocious puberty （CPP）. METHODS From the societal perspective and based on a real-world study conducted at West China Second Hospital of Sichuan University， the cost-effectiveness analysis was performed to compare the long-term cost-effectiveness of two pharmacotherapy regimens for CPP girls， with final height as outcome indexes， using per capita disposable income of rural residents and urban residents （20 133-49 283 yuan） in 2022 as the social willing-to-pay （WTP） threshold. The robustness of the basic analysis result was verified by using one-way sensitivity analysis and probability sensitivity analysis， and the cost-effectiveness of different combinations of long-acting preparations was compared using scenario analysis. RESULTS The basic analysis result showed that the combination therapy regimen required an additional cost of 25 193.49 yuan for every one-centimeter improvement in the final height of girls with CPP compared with the monotherapy regimen， which was not cost-effective for residents in rural areas， but it was cost-effective for residents in urban areas. One-way sensitivity analysis showed that the uncertain factors with potential impacts on the results were， in order， the price of rhGH， the final height of pediatric patients in the combination therapy regimen group， the course of rhGH in the combination therapy regimen group， and the final height of pediatric patients in the monotherapy regimen group. Probabilistic sensitivity analysis indicated that the probability of the combination therapy regimen being cost-effective was higher than that of the monotherapy regimen when WTP was more than 26 010 yuan/cm. When GnRHa long-acting preparation was used for intramuscular injection every 3 months， the combination therapy regimen was not cost-effective for rural residents， but was cost-effective for urban residents； when rhGH long-acting preparation was injected subcutaneously once a week， the combination therapy regimen was not cost-effective for residents in both rural areas and urban areas. CONCLUSIONS The combination of GnRHa and rhGH is only recommended for CPP children with better affordability to improve final height. The benefits， risks， and affordability of treatment should be comprehensively considered before the decisions on pharmacotherapy， to avoid abuse of rhGH due to the blind pursuit of height growth.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective:To discuss the effect of quorum sensing-related gene expression on biofilm formation and drug resistance in clinically multidrug-resistant Pseudomonas aeruginosa,and to clarify the mechanism of enhacing drug resistance.Methods:A total of 77 strains of Pseudomonas aeruginosa were collected.Based on drug resistance,the strains were divided into multidrug-resistant group and sensitive group.The optimal biofilm formation conditions were determined using the microtiter plate method;biofilm formations of the stains in both groups was observed under an optical microscope;crystal violet staining was used to semiquantitatively detect biofilm formation ability of P.aeruginosa in both groups;microbroth dilution method was used to determine the minimal inhibitory concentration(MIC)values of the quorum sensing inhibitor(C-30)against Pseudomonas aeruginosa in both groups;RNA was extracted from two groups using a commercial kit,while RNA from planktonic state and biofilm state of multidrug-resistant strains was extracted using modified TRIzol method;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the mRNA expression levels of quorum sensing-related genes(lasR/I,RhlR/I,PqsR/A)of the stains in multidrug-resistant group and sensitive group,as well as before and after adding the quorum sensing inhibitor C-30.Results:Among 77 strains of Pseudomonas aeruginosa,56 were multidrug-resistant(multidrug-resistant group)and 21 were fully sensitive(sensitive group).Optimal biofilm formation occurred at a bacterial concentration of 1.5×108 CFU·mL-1 with 48 h incubation.The biofilm positivity rate was 91%,with strongly positive,moderately positive,weakly positive,and negative biofilms accounting for 16%,34%,41%,and 9%,respectively.The biofilm positivity rate in multidrug-resistant strains was 96%,and biofilm formation ability in multidrug-resistant group was higher than that in sensitive group(P<0.05).When the concentration of C-30 was 8 mg·L-1 the biofilm formation in most Pseudomonas aeruginosa was inhibited,with enhanced suppression at higher concentrations.The absorbtion(A)value of both planktonic-state and biofilm-state RNA ranged from 1.8 to 2.0.The RT-qPCR results showed that compared with planktonic state,the expression levels of lasR/I,RhlR/I,and PqsR/A mRNA of the stains in biofilm state were significantly increased(P<0.01).Compared with non-inhibitor group,the expression levels of lasR/I,RhlR/I,and PqsR/A mRNA in biofilm state of inhibitor-treated group were significantly decreased(P<0.01).Conclusion:High expression of quorum sensing-related genes in multidrug-resistant P.aeruginosa promotes biofilm formation,thereby enhancing drug resistance.

Objective:To investigate the preventive and therapeutic effects and mechanisms of Dachaihu decoction(DCD)on dextran sodium sulfate(DSS)-induced ulcerative colitis(UC)and liver injury in mice,as well as the association between DCD benefits and gut microbiota modulation.Methods:Mice were treated with DCD(20.10 and 10.05 g/kg)for 2 weeks,with free access to drinking water containing 3%DSS in the second week to induce UC.Histopathological examination,RT-qPCR and 16S rRNA sequencing were used to investigate the effect of DCD on UC mice.Results:DCD pretreatment significantly alleviated weight loss,bloody diarrhea with mucus,histopathological abnormalities of the colon,and colon shortening in mice with DSS-induced UC.In addition,DCD pretreat-ment significantly upregulated the levels of Occludin,ZO-1,and MUC-2 in the colon and protected the intestinal barrier of mice.DCD pretreatment also alleviated inflammatory cell infiltration in the colon and the liver and significantly reduced the expression levels of the proinflammatory factors such as IL-1β,IL-6,TNF-α,iNOS,COX-2,and NLRP3,thereby exerting a protective effect against UC and liver injury.It should be noted that DCD corrected gut micro-biota imbalance in UC mice by enriching probiotic bacteria such as Lactobacillus and Bifidobacterium and reducing harmful bacteria such as Norank_f_Desulfovibrionaceae and Escherichia-Shigella.Conclusion:DCD can alleviate DSS-induced UC and exert a liver-protecting effect by protecting intestinal barrier,inhibiting inflam-mation,and regulating gut microbiota.

Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

Objective To explore the biological functions of pyroptosis-related genes in pneumonic plague using bioinformatics methods,and to evaluate their potential applicability as diagnostic markers.Methods The pneumonic plague-related dataset GSE220123 was retrieved from the Gene Expression Omnibus(GEO)database and screened for differentially expressed pyroptosis-related genes(DE-PRGs).The functions of DE-PRGs were studied via Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses,and immune infiltration analysis.The hub genes were identified via protein-protein interaction(PPI)network analysis,and further screened for key genes with sustained high expression characteristics based on differential expression analysis.The relative expression levels of the key genes were verified using the reverse transcription real-time quantitative PCR(qPCR)method.Results A total of 17 DE-PRGs were screened,and PPI network analysis revealed 7 Hub genes.Among them,Casp4 continued to be up-regulated during the course of pneumonic plague.The results of reverse transcription qPCR were consistent with the those of bioinformatic analyses.Conclusion DE-PRGs play a crucial role in the immune response of pneumonic plague,especially Casp4,which has significant applications as a diagnostic biomarker and potential therapeutic target for pneumonic plague.

Objective To explore the characteristics of the cross-sectional area(CSA)of the vagus nerve in a healthy population in Qujing,Yunnan,and its correlation with demographic characteristics.Methods High-resolution nerve ultrasound examinations were conducted on the vagus nerve of 201 healthy volunteers from a hospital in Qujing,Yunnan from September 2022 to March 2023.The CSA was measured through transverse scans of the vagus nerve.The correlation of vagus nerve CSA with age,body mass index(BMI),and gender was assessed.Results The mean CSA of the bilateral VN were 1.9 mm2(right)and 1.3 mm2(left),respectively.The average CSA of the right vagus nerve was significantly greater than that of the left(P<0.001).In the high-age group(>50 years),the average CSA of the right vagus nerve was significantly higher than that of the low-age group(≤50 years)(P=0.0142).However,there was no statistically significant difference in the average CSA of the right vagus nerve between the BMI>24 kg/m2 group and the≤24 kg/m2 group(P=0.0852).The average CSA of the left vagus nerve showed no statistically significant differences across different age groups and BMI groups(P>0.05),but the average CSA of the bilateral vagus nerve in the male group was greater than that in the female group,with a statistically significant difference(P<0.05).Correlation analysis further confirmed a negative correlation between the average CSA of the right vagus nerve and age(r=-0.17,P=0.0139).Multiple linear regression models indicated that age(P=0.007)and gender(P=0.001)were independent influencing factors for the average CSA of the right vagus nerve.Conclusion In the healthy population of Qujing,Yunnan,the CSA of the right vagus nerve is significantly greater than that of the left,and males also exhibit a significantly greater CSA than females.With increasing age,the vagus nerve gradually becomes thinner.

OBJECTIVE To reduce dispensing errors in pharmacy intravenous admixture service （PIVAS） of children’s hospitals. METHODS The risk of dispensing procedures in our PIVAS was identified by applying failure mode and effect analysis （FMEA） model. Potential failure modes that might lead to dispensing errors in each link were determined， and failure causes were analyzed. The severity， incidence and detection degree of potential failure modes were quantitatively scored， and their risk priority number （RPN） was calculated to screen failure modes that needed to be improved in priority； the corresponding improvement measures were developed by 6S management method from six aspects， namely， finishing （seiri）， rectifying （seiton）， sweeping （seiso）， sanitation （seiketsu）， literacy （shitsuke） and safety. The effect of intervention before and after rectification was evaluated. RESULTS Based on the RPN， 32 potential failure modes were selected， of which a total of 18 critical failure modes that needed to be improved in priority. After implementing corresponding measures according to 6S management method， the RPN of 18 critical failure modes decreased. The total RPN decreased from 497 to 142 with a decrease rate of 71.43%. The error rates of 15 critical failure modes were significantly lower than before implementation （P＜0.05）. CONCLUSIONS Applying FMEA model and 6S management method to the risk control of all aspects of PIVAS workflow can effectively reduce the risk of PIVAS dispensing errors and ensure the safety of children’s intravenous medication.
