The concept of "qi deficiency with stagnation" refers to a pathological state characterized by the depletion of primordial qi， impaired qi transformation， and the development of internal stagnation. Under the cyclic chemotherapy regimen in oncology， chemotherapy-induced myelosuppression follows a progressive pathological course from qi deficiency to increasing stagnation. This sequential evolution from mild to severe myelosuppression closely aligns with the dynamic syndrome differentiation and treatment framework of "qi deficiency with stagnation". "Qi deficiency" reflects the gradual depletion of qi， blood， and essence， while "stagnation" refers to the accumulation of phlegm， turbid dampness， and blood stasis. These two components interact reciprocally， forming a vicious cycle where deficiency leads to stagnation， and stagnation further damages the healthy qi. In the early stage of mild myelosuppression， chemotoxicity begins to accumulate in the bone marrow， leading to qi consumption， blood deficiency， yin injury， and the gradual formation of turbid phlegm and damp stagnation. In the advanced stage of severe myelosuppression， the accumulation of toxicity causes qi sinking， exhaustion of essence， and marrow depletion， along with blood stasis obstructing the collaterals. Treatment strategies should be based on syndrome differentiation， with an emphasis on assessing the severity of the condition， balancing deficiency and excess， and achieving both symptomatic relief and root cause resolution.

[Purpose]To investigate the potential causal relationships between serum levels of trace elements and head and neck cancers.[Methods]Single nucleotide polymorphism(SNP)of oral cancer,oropharyngeal cancer,laryngeal cancer and thyroid cancer,associated with calcium,copper,iron,magnesium,zinc,were obtained from genome-wide association studies(GWAS).A two-sample bidirectional Mendelian randomization(MR)analysis was performed using the inverse variance weighting(IVW)method by calculating odds ratio(OR)and 95％confidence interval(CI).Pleiotropy was assessed using MR-PRESSO and MR-Egger regression,and sensitivity analysis was conducted via the"leave-one-out"method.[Results]IVW analysis revealed a causal association between serum magnesium levels and the incidence of oral cancer(OR=0.976,95％CI:0.956～0.997,P=0.025),also between thyroid cancer and serum calcium levels(OR=1.008,95％CI:1.001～1.015,P=0.023).No significant causal associations were observed between other trace ele-ments and head and neck cancers(all P＞0.05).[Conclusion]This MR study suggests that serum magnesium levels serve as a protective factor against oral cancer,while thyroid cancer leads to el-evated serum calcium levels.

Prostate cancer is one of the most common male urological malignancies,in which bone metastasis of desmo-plasia-resistant prostate cancer is an important stage in the progression of the disease,which seriously affects the quality of life and survival of patients.With the development of nuclide therapy technology in recent years,223-Ra,as a new type of alpha-targeted therapy,has shown good efficacy in the treatment of desmoplasia-resistant prostate cancer bone metastasis.The purpose of this pa-per is to review the characteristics,mechanism of action,treatment,and the main research results of its treatment of desmoplasia-resistant prostate cancer bone metastasis,and provide a comprehensive review of the clinical application of 223-Ra in the treatment of desmoplasia-resistant prostate cancer bone metastasis for the clinical application of 223-Ra in prostate cancer bone metastasis.

OBJECTIVE To investigate the epidemiological characteristics of respiratory human adenovirus(H AdV)infections in hospitalized children in Ningbo,and to provide data for formulating infection prevention and control strategies for HAdV.METHODS A total of 65 022 children hospitalized with respiratory infections at the Women and Children's Hospital of Ningbo University from Jul.2019 to Dec.2024 were selected as the study sub-jects.Multiple reverse transcription-polymerase chain reaction(RT-PCR)and capillary electrophoresis were used to detect 11 non-bacterial pathogens.Basic and clinical information of the children was collected for analysis.RESULTS A total of 65 022 specimens were tested,with 4 292 cases tested positive for HAdV positivity,yielding a positive rate of 6.60％.The lowest positive rate was observed in 2023(3.22％),while the highest was in 2024(13.97％).Compared to the years 2019-2023,the overall HAdV positive rate was high in 2024,peaking at 26.80％in Jun.,indicating an outbreak.The total HAdV positive rate was higher in boys(6.82％)than in girls(6.32％)(P=0.006).The highest HAdV positive rate was observed in the 2 to＜6 age group(9.00％),while the lowest was in the 0 to＜1 age group(2.33％).Among the HAdV-positive specimens,2 658 cases(61.93％)were single infections,and 1 634 cases(38.07％)were co-infections.The non-bacterial respiratory pathogens with the highest co-infection rates were human rhinovirus(34.09％),Mycoplasma pneumoniae(20.44％)and human parainfluenza virus(5.75％).CONCLUSIONS A n outbreak of HAdV infections is observed among hospitalized children in Ningbo in 2024.Higher positive rates are found in boys aged 2 to＜6 years,with a certain proportion of co-infections.

Objective To explore the application of information technology in the management of the new outpatient Pharmacy of Beijing Chaoyang hospital,and to provide references for the construction or operational management of new hospital campuses in other institutions.Methods BI technology,Apriori algorithm,and activity based classification(ABC)method were utilized to optimize the allocation of personnel,drug storage locations,and cargo positions in the new outpatient dispensing center.The window prescription volume,number of dispensing positions,average dispensing time,and average patient waiting time were compared before and after the optimization.Results With the continuous increase in prescription volume at the new hospital campus,the average dispensing time and average patient waiting time decreased significantly from(143.80±15.62)s and(325.43±39.29)s to(100.26±17.85)s and(222.56±39.84)s,respectively(P<0.05).Conclusion Information pharmacists can optimize human resources and drug storage locations through BI technology,Apriori algorithm,and ABC method,providing valuable references for the management of outpatient dispensing centers in newly opened hospital campuses.

The killing effect of radiation therapy on healthy cells has led to the creation of targeted radionuclide therapy,which effectively reduces the damage to surrounding normal cells.At present,alpha(α)and beta(β)radionuclides are the research hotspots of targeted therapy.Numerous preclinical and clinical studies have shown that radiation therapy not only has local anti-tumor effects,but also exerts systemic anti-tumor effects by triggering the body's immune response.This paper describes in detail the characteristics and clinical applications of commonly used radionuclides,and discusses the mechanism of radiation-triggered body immune response as well as the related research on the combined use of radiation therapy,targeted radionuclide therapy and immunotherapy.
