OBJECTIVE To establish a Chinese drug-related problem （DRP） classification system applicable to pharmacist-led pharmaceutical care in China， providing pharmacists with an effective and practical tool for pharmaceutical care. METHODS A multi-stage process was employed to construct the DRP classification system， including literature review and analysis， comparison of existing classification systems， refinement of classification items and framework development， two rounds of standard case validation， expert discussion， and system revision. The Fleiss′ kappa test was used to calculate the consistency coefficient κ， assessing the reliability of pharmacists participating in evaluating the classification system. An electronic questionnaire comprising six items was employed to evaluate the system’s applicability. RESULTS The constructed Chinese DRP classification system comprised six sections [problem（including potential problems）， DRP evaluation， cause （including possible causes of potential problems）， intervention， acceptance of intervention and DRP status]， with 24 primary codes and 96 secondary codes. In the first round of case validation， κ values exceeded 0.4 for all sections except “intervention” and “DRP status”. In the second round， κ values exceeded 0.4 for all sections. In the applicability evaluation of the classification system， positive ratings （“strongly agree” or “agree”） exceeded 85% for all items. Specifically， positive ratings for“the classification system can provide appropriate category selection”，“ the classification system is comprehensive”，“ the classification system is convenient to use” and “the classification system is highly satisfactory” exceeded 92%. CONCLUSIONS The Chinese DRP classification system developed demonstrates both high reliability and applicability， providing an effective and practical classification tool for pharmacists in China to conduct pharmaceutical care.

Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

ObjectiveTo investigate the epidemiological and clinical characteristics of human bocavirus (HBoV) in hospitalized children with acute lower respiratory tract infection (ALRTI) at a single-center children’s hospital in Shanghai, thereby providing evidence for the diagnosis, treatment, and prevention of HBoV infection. MethodsA retrospective study was conducted on 19 537 hospitalized children with ALRTI at Shanghai Children’s Hospital from January 2021 to December 2023. Multiplex polymerase chain reaction (PCR) combined with capillary electrophoresis was used to detect HBoV and 12 other common respiratory viruses /atypical pathogens. The positive detection rate, demographic characteristics (sex, age), temporal distribution (year, season) of HBoV, as well as the clinical characteristics of severe and non-severe pneumonia were analyzed. ResultsThe overall HBoV-positive rate was 2.57% (503/19 537), with 59.44% (299/503) being single infections and 40.56% (204/503) being co-infections. The positive detection rate was significantly higher in boys than that in girls (2.78% vs 2.33%, χ²=3.88, P=0.049). The highest infection rate was observed in toddlers, followed by infants (χ²=379.57, P<0.001). The positive rate peaked in 2021 and reached its lowest point in 2023 (χ²=45.49, P<0.001), with epidemics mainly prevalent in summer and autumn. The main clinical symptoms were cough (90.06%, 453/503), fever (75.94%, 382/503), and wheezing (39.96%, 201/503). Children with severe pneumonia showed a higher incidence of wheezing compared with the non-severe group (P<0.001), while underlying diseases and co-infections had no significant association with disease severity (P>0.05). ConclusionHBoV was an important pathogen of ALRTI in children, predominantly affecting infants and toddlers, with higher susceptibility in boys and seasonal peaks in autumn and summer. The main clinical manifestations included cough, fever, and wheezing, with wheezing being more prevalent in children with severe pneumonia.

Objective: To analyze the occupational health literacy (OHL) level and its influencing factors among key populations in the tertiary industry in Lu'an City, Anhui Province, so as to provide a basis for developing targeted health interventions and improving regional occupational health policies. Methods: A stratified cluster random sampling method was employed to select five categories of key populations from the tertiary industry in Lu'an City as study subjects from August to September 2024. Data on gender, age, education level, and OHL were collected through the National OHL Monitoring Questionnaire for Key Populations. The OHL levels were analyzed, and influencing factors of OHL levels among key populations were analyzed using a multivariable logistic regression model. Results: A total of 1 243 individuals were surveyed, comprising 700 (56.32%) males and 543 (43.68%) females. The median age was 42.00 (interquartile range, 17.00) years. There were 609 individuals with OHL, and the OHL level was 48.99%. The OHL levels in fundamental knowledge of occupational health protection, healthy work styles and behaviors, knowledge of occupational health laws, and basic skills for occupational health protection were 84.71%, 60.34%, 43.93%, and 37.09%, respectively. Multivariable logistic regression analysis showed that educational level (primary school and below, OR=0.149, 95%CI: 0.064-0.344; junior high school, OR=0.340, 95%CI: 0.184-0.629; high school, OR=0.408, 95%CI: 0.230-0.723), average monthly personal income (3 000-<5 000 yuan, OR=1.655, 95%CI: 1.092-2.508; 5 000-<7 000 yuan, OR=2.195, 95%CI: 1.302-3.699; ≥7 000 yuan, OR=2.062, 95%CI: 1.016-4.183), employer nature (private enterprises, OR=2.992, 95%CI: 1.569-5.443), and industry category (education, OR=3.423, 95%CI: 1.407-8.327; courier / food delivery services, OR=0.459, 95%CI: 0.268-0.787; healthcare, OR=7.539, 95%CI: 3.255-17.461) were statistically associated with the OHL level among key population. Conclusion The OHL level among key population in the tertiary industry of Lu'an City can be further enhanced, with educational level, average monthly personal income, employer nature, and industry category identified as the primary influencing factors.

Objective:To investigate the characteristics of vitamin D levels in children in Gansu Province,and to analyze the correlation between vitamin D levels and immune disorders in children with recurrent respiratory tract infections(RRTIs).Methods:From January 2020 to December 2021,9 790 cases of children aged 0～6 years who received vitamin D detection in pediatric depart-ment of maternal and Child health care hospitals and tertiary general hospitals in 6 cities and prefectures of Gansu Province were retro-spectively selected,characteristics of vitamin D in 5 000 children were analyzed.Ninty children with RRTIs in 5 000 children were taken as study group,and 80 healthy children were taken as control group.Correlation between vitamin D levels and immune function indexes(IgA,IgG,IgM,complement C3 and complement C4)between the two groups was compared to analyze the diagnostic value of vitamin D for children RRTIs.Results:After analyzing vitamin D data of 5 000 children in Gansu Province,it was found that vita-min D deficiency rate,deficiency rate and adequate rate were 11.58%,41.38%and 47.04%respectively,and no vitamin D overdose or poisoning were found.Vitamin D level of children was affected by age and season.Vitamin D deficiency of children aged 3 to 4 years was more serious,and vitamin D level of children in winter was the lowest,and vitamin D level was related to the growth and develop-ment of children and disease.25(OH)D level and immune function indexes in study group were lower than those in control group(P<0.05).Level of 25(OH)D was related to the age,allergic history,passive tobacco exposure and susceptible season of RRTIs(P<0.05).Immune function indexes of children with adequate vitamin D were higher than children with insufficient and deficient vitamin D(P<0.05).Level of vitamin D in children with RRTIs was positively correlated with their immune function(P<0.05).Low birth weight,premature delivery,preference for food,daily amount of fruits and vegetables,outdoor activity time,calcium,iron,zinc,25(OH)D,IgA,IgG,IgM,complement C3 and C4 were all independent risk factors for RRTIs in children(P<0.05).Vitamin D had a high diagnostic value for RRTIs in children(P<0.05).Conclusion:Vitamin D level of children in Gansu Province is related to age and season.Lower vitamin D level in children's RRTIs is related to the immune disorders of children,which can be used for the diag-nosis of this disease.

Constitutive androstane receptor(CAR),a pivotal member of the nuclear receptor superfamily,is predominantly expressed in the liver and intestine.It plays a central role in orchestrating the metabolic clearance of xenobi-otics and endogenous metabolites.Unlike classical nuclear receptors,CAR exhibits constitutive transcriptional activity in the absence of ligands.In addition to its well-established function in regulating genes involved in drug metabolism and transport,accumulating evidence highlights its broader regulatory capacity in glucose and lipid homeostasis,bile acid me-tabolism,hormonal balance,and cellular proliferation.Furthermore,aberrant CAR signaling has been associated with the development and progression of multiple pathological conditions,including hepatic steatosis,diabetes,cancers,and car-diovascular diseases.This review summarizes the biological functions of CAR and its pathophysiological significance.

Objective To investigate the impact of mild hippocampal atrophy on life quality of patients with Parkinson's disease(PD)and its correlation with cognitive function.Methods A total of 34 PD patients were recruited from Nanjing Brain Hospital,assessed using the Unified Parkinson's Disease Rating Scale(UPDRS),the Parkinson's Disease Questionnaire(PDQ-39)and the Montreal Cognitive Assessment(MoCA),and underwent MRI scans to measure hippocampal volume.Results Compared with the PD without hippocampal atrophy(PD-nHA)group,the PD with hippocampal atrophy(PD-HA)group showed significantly higher age,PDQ-39 total score,and subscores in physical activity,daily living,cognition,and communication dimensions,along with significantly lower MoCA scores,total hippocampal volume,and bilateral posterior hippocampal volume(all P＜0.05).MoCA subdomain analysis revealed that the PD-HA group exhibited varying degrees of decline across visuospatial/executive function,naming,attention,language,abstraction,delayed recall,and orientation domains,although these differences did not reach statistical significance(all P＞0.05).Total hippocampal volume was negatively correlated with PDQ-39 scores in physical activity,cognition,communication,and total score(r=-0.453,P=0.007;r=-0.364,P=0.034;r=-0.355,P=0.039;r=-0.369,P=0.032),and positively correlated with MoCA total score and three cognitive domains:naming,language,and orientation(r=0.408,P=0.017;r=0.348,P=0.044;r=0.406,P=0.017;r=0.355,P=0.039).The PDQ-39 total score was negatively correlated with the MoCA total score(r=-0.468,P=0.005).Compared with baseline,the PD-HA group showed significantly increased PDQ-39 scores(t=2.378,P=0.039)and significantly decreased right anterior hippocampal gray matter volume(t=-2.751,P=0.022)at the final follow-up,while differences in total hippocampal volume and other hippocampal subregions were not statistically significant(all P＞0.05).MoCA scores showed a declining trend but did not reach statistical significance(t=-0.958,P=0.361).In the PD-nHA group,no statistically significant differences were observed in PDQ-39 scores,MoCA scores,or hippocampal volumes between baseline and final follow-up(all P＞0.05).Conclusions Hippocampal atrophy is closely related to cognitive decline and reduced quality of life in PD patients.Particularly,posterior hippocampal atrophy is more closely related to cognitive dysfunction,and cognitive function serves as a mediator between hippocampal atrophy and quality of life.Early interventions targeting cognitive impairment may help improve the quality of life for PD patients.

Objective:To investigate the current status and influencing factors of decision anxiety in guardians of children with acute appendicitis under Endoscopic retrograde appendicitis therapy (ERAT) background, and to provide reference for the development of targeted intervention programs for decision anxiety.Methods:Convenient sampling method was used to select 254 guardians of children with acute appendicitis treated in the Department of Pediatrics, Second Affiliated Hospital of PLA Air Force Medical University from February 2023 to April 2024. A cross-sectional survey was conducted using the General Data Questionnaire, the State-Trait Anxiety Inventory Form Y-State anxiety subscale and the Preparation for Decision Making Scale. Multiple linear regression was used to analyze the influencing factors in guardians of children with acute appendicitis.Results:Among the guardians of 254 children with acute appendicitis, 156 were males and 98 were females, aged (37.44 ± 3.63) years old. The decision anxiety score of guardians of children with acute appendicitis was (52.49 ± 6.54). The results of multiple linear regression showed that age of children, gender of guardian, education level of guardian, per capita monthly income of family, decision making tendency and decision preparation were the main influencing factors of decision anxiety in guardians of children with acute appendicitis ( t values were -7.07-3.58, all P<0.05), which could explain 64.4% of the total variation. Conclusions:The decision anxiety in guardians of children with acute appendicitis is at a high level. Medical staff should provide targeted decision guidance, improve decision assistance programs and provide more effective decision support for guardians of children with acute appendicitis.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.
