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.

ObjectiveTo investigate the effects of zinc finger E-box binding homeobox 1 （ZEB1） on the proliferation， migration， and invasion of lung adenocarcinoma H322 cells， as well as its underlying molecular mechanisms. MethodsThe gene expression characteristics of the transcription factor ZEB1 in lung adenocarcinoma were analyzed using data from the GEO and TCGA public databases. RT-qPCR and Western blot were employed to measure mRNA and protein expression levels of ZEB1 in lung adenocarcinoma cell lines （H322， A549， 95-D） and normal human bronchial epithelial cells （BEAS-2B）. Lentiviral transduction was utilized to establish stable ZEB1-overexpressing （Oe-ZEB1） and vector control （Oe-NC） H322 cell lines. Cell proliferation was assessed using CCK-8， colony formation， and EdU assays， while apoptosis was evaluated by Hoechst33258/PI double staining. Wound healing and Transwell assays were performed to examine cell migration and invasion capabilities. Cell cycle distribution was determined by flow cytometry， and Western blot was used to analyze protein expression changes in relevant signaling pathways. ResultsThe findings from GEO and TCGA indicated that ZEB1 expression in lung adenocarcinoma varied with tumor malignancy grade. RT-qPCR and Western blot analyses revealed significantly higher ZEB1 expression in lung adenocarcinoma cell lines compared to BEAS-2B cells （P0.05）. Results from the CCK-8， colony formation， EdU， wound healing， and Transwell assays demonstrated that， compared with the un-transfected control （Control） group， Oe-ZEB1 H322 cells exhibited enhanced proliferation， migration， and invasion capabilities （P0.05）. Hoechst33258/PI double staining and flow cytometry analyses showed that， relative to the Control group， apoptosis was reduced in Oe-ZEB1 H322 cells （P0.05）. Additionally， a decreased proportion of cells in the G₁ phase and an increased proportion in the S phase were observed in Oe-ZEB1 cells， indicating accelerated cell cycle progression. Western blot analysis further revealed that， compared with the Control group， Oe-ZEB1 H322 cells exhibited upregulated expression of N-cadherin， mutant p53 （mutp53）， and Cyclin D1 （P0.05）， while expression levels of E-cadherin， murine double minute 2 （MDM2）， and p21 were downregulated （P0.05）. ConclusionOverexpression of ZEB1 promotes the proliferation， migration， and invasion of lung adenocarcinoma H322 cells and may facilitate cell cycle progression by modulating the MDM2/mutp53/p21 signaling pathway， thereby promoting the transition of cells from the G₀/G₁ phase to the S phase.

AIM: To investigate differences in ocular biological parameters and refractive status among children with unilateral congenital ptosis.METHODS:This was a retrospective cohort study enrolling patients with unilateral congenital ptosis in the Department of Ophthalmology, Xi'an Children's Hospital between August 2018 and March 2025, with the contralateral healthy eyes serving as the control group. All patients underwent a detailed ophthalmic examination to assess the degree of ptosis and evaluate refractive errors. Biometric measurements were performed using the IOL Master 700 biometer, including axial length(AL), central corneal thickness(CCT), anterior chamber depth(ACD), lens thickness(LT), and astigmatism(AST).RESULTS:A total of 100 eyes from 100 children(affected eye group)with unilateral congenital ptosis were enrolled, and their 100 contralateral normal eyes without ptosis were set as the control group(healthy eyes group). Among the subjects, there were 67 males(67%)and 33 females(33%), with a mean age of 6.43±2.47 y; 45 affected eyes were the right eye and 55 were the left eye. Among the 100 patients, mild, moderate, and severe ptosis accounted for 7%, 21%, and 72%, respectively. The incidence of amblyopia in patients with unilateral congenital ptosis was 32%, all of which occurred in the affected eye. Compared with the healthy eye group, K2(total)and K2(severe ptosis)in eyes with severe ptosis were significantly lower(P<0.05), indicating that the cornea in the ptotic eye was flatter. In patients with moderate ptosis, the affected eye had a significantly greater corneal thickness(CCT)compared to the healthy eye(P<0.05), indicating that the corneas of eyes with moderate ptosis were thicker. The incidence of against-the-rule and oblique astigmatism in the affected eye group(39%)was significantly higher than that in the healthy eye group(14%); there was a significant difference in the corneal astigmatism axis between the affected and healthy eye groups(P<0.01). There were no differences in refractive status or biological parameters such as AL, K1, AST, ACD, and LT between the affected and healthy eyes.CONCLUSION:Congenital ptosis can affect refractive errors, lead to oblique and against-the-rule astigmatism, increase the prevalence of amblyopia, and also result in corneal thickening and flattening. However, it has minimal effects on AL, LT, and ACD.

Metachromatic leukodystrophy (MLD) is an inherited disease caused by a deficiency of the enzyme arylsulfatase A (ARSA). Lentivirus-modified autologous hematopoietic stem cell gene therapy (HSCGT) has recently been approved for clinical use in pre and early symptomatic children with MLD to increase ARSA activity. Unfortunately, this advanced therapy is not available for most patients with MLD who have progressed to more advanced symptomatic stages at diagnosis. Patients with late-onset juvenile MLD typically present with a slower neurological progression of symptoms and represent a significant burden to the economy and healthcare system, whereas those with early onset infantile MLD die within a few years of symptom onset. We conducted a pilot study to determine the safety and benefit of HSCGT in patients with postsymptomatic juvenile MLD and report preliminary results. The safety profile of HSCGT was favorable in this long-term follow-up over 9 years. The most common adverse events (AEs) within 2 months of HSCGT were related to busulfan conditioning, and all AEs resolved. No HSCGT-related AEs and no evidence of distorted hematopoietic differentiation during long-term follow-up for up to 9.6 years. Importantly, to date, patients have maintained remarkably improved ARSA activity with a stable disease state, including increased Functional Independence Measure (FIM) score and decreased magnetic resonance imaging (MRI) lesion score. This long-term follow-up pilot study suggests that HSCGT is safe and provides clinical benefit to patients with postsymptomatic juvenile MLD.

OBJECTIVE: Xuebijing injection has been recommended as a therapeutic approach for individuals with severe and critical COVID-19. This study aims to explore the correlation of neutrophil to lymphocyte platelet ratio (NLPR) with the severity and prognosis of COVID-19, and the effect of XBJ on the prognosis of patients with COVID-19 in different inflammatory states. METHODS: This was a retrospective study conducted at Wuhan Union Hospital in China. COVID-19 patients admitted between November 1, 2022 and February 1, 2023 were included. In predicting prognosis for individuals with COVID-19, new inflammatory indicators were used, and their prognostic value was assessed by using Cox regression models and receiver operating characteristic curves. Furthermore, a calculation was made to determine the cutoff value for NLPR. Relative risk and Cox regression models were used to examine the effects of Xuebijing injection on prognosis in patient cohorts that had been stratified by the NLPR cutoff. RESULTS: This research included 455 participants with COVID-19, with a mean age of 72 years. Several inflammatory indicators were found to be strongly correlated with prognosis, and NLPR shows the greatest predictive power. Patients with NLPR > 3.29 exhibited a mortality rate of 17.3%, which was 6.2 times higher than in patients with NLPR ≤ 3.29. Importantly, providing Xuebijing injection to patients with NLPR > 3.29 was associated with a lower risk of 60-day all-cause mortality. However, there was no discernible improvement in survival among patients with NLPR ≤ 3.29 who received Xuebijing injection. CONCLUSION NLPR is the most reliable inflammatory marker for predicting prognosis among individuals with COVID-19, and can accurately identify individuals who may benefit from Xuebijing injection.

OBJECTIVE: To determine the prevalence of lumbar spondylolysis (LS) and the proportion of spondylolytic spondylolisthesis (SS) in China, and to evaluate the musculoskeletal status of patients with LS and SS. METHODS: Spine Computed Tomography (CT) images were collected from community populations aged 40 and above in a nationwide multi-center project. LS was diagnosed, and SS was graded by an experienced radiologist. Bone mineral density (BMD) and paraspinal muscle parameters were quantified based on CT images. RESULTS: One hundred and seventeen patients of a total of 3,317 individuals were diagnosed with LS, corresponding to a prevalence rate of 3.53%. 63 of the 1,214 males (5.18%) and 54 of the 2,103 females (2.57%) were diagnosed with LS. SS occurred in 64/121 vertebrae (52.89%). BMD was not associated with LS ( P = 0.341). The L5 extensor paraspinal muscle density was higher in the LS group than in the non-LS group. In the LS group, patients with SS had a smaller L5 paraspinal extensor muscle cross-sectional area than those without SS ( P = 0.003). CONCLUSION The prevalence of LS in Chinese adults was 3.53%, with prevalence rates of 5.18% in males and 2.57% in females. Patients with LS have higher muscle density, whereas those with SS have smaller muscle cross-sectional areas at the L5 level.

OBJECTIVE: CRISPR-Cas protects bacteria from exogenous DNA invasion and is associated with bacterial biofilm formation and pathogenicity. METHODS: We analyzed the type I-F CRISPR-Cas system of Legionella pneumophila WX48, including Cas1, Cas2-Cas3, Csy1, Csy2, Csy3, and Cas6f, along with downstream CRISPR arrays. We explored the effects of the CRISPR-Cas system on the in vitro growth, biofilm-forming ability, and pathogenicity of L. pneumophila through constructing gene deletion mutants. RESULTS: The type I-F CRISPR-Cas system did not affect the in vitro growth of wild-type or mutant strains. The biofilm formation and intracellular proliferation of the mutant strains were weaker than those of the wild type owing to the regulation of type IV pili and Dot/Icm type IV secretion systems. In particular, Cas6f deletion strongly inhibited these processes. CONCLUSION The type I-F CRISPR-Cas system may reduce biofilm formation and intracellular proliferation in L. pneumophila.

Objective : To establish a method for measuring major organic acids in the tricarboxylic acid cycle using a high-performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS) system, and to investigate the changes in six tricarboxylic acid cycle organic acids(fumaric acid, malic acid, succinic acid, α-ketoglutaric acid, cis-aconitic acid, and citric acid) in the serum, liver, and placenta of mice exposed to di(2-ethylhexyl) phthalate(DEHP) during pregnancy. Methods : The serum, liver and placental samples from pregnant mice were processed and eluted through a Waters ACQUITY UPLC BEH Amide Column(130 Å, 1.7 μm, 2.1 mm × 150 mm) using a gradient elution program. Mobile phase A comprised an aqueous solution of 10 mmol/L ammonium acetate and 5 μmol/L methanephosphonic acid, while mobile phase B consisted of a 90% acetonitrile aqueous solution containing 10 mmol/L ammonium acetate and 5 μmol/L methanephosphonic acid, with a flow rate maintained at 0.35 ml/min. The mass spectrometry detection system utilized an electrospray ionization technique with negative ion mode for multiple reaction monitoring. Results : The correlation coefficients of the standard curves for the six tricarboxylic acid cycle organic acid metabolites were all above 0.996 within the quantitative range. The method's accuracy ranged from 97.14% to 108.26%, with inter-day and intra-day precision relative standard deviation between 1.35% and 6.73%. The matrix effect was between 93.29% and 107.47%, and the extraction recovery rate ranged from 94.82% to 112.57%. Analysis of six tricarboxylic acid cycle organic acids in the liver, serum, and placenta of DEHP-exposed mice during pregnancy showed significant reductions in fumaric acid, malic acid, α-ketoglutaric acid, cis-aconitic acid, and citric acid compared to the control group(P<0.05). Conclusion The HPLC-MS/MS method established in this study for detecting six tricarboxylic acid cycle organic acids in the serum, liver, and placenta of DEHP-exposed pregnant mice is stable, highly sensitive and selective. Prenatal DEHP exposure induced alterations in the levels of tricarboxylic acid(TCA) cycle organic acid metabolites in the liver, serum, and placenta of mice, suggesting that DEHP exposure during pregnancy may interfere with mitochondrial TCA cycle processes. These findings indicate potential value in the diagnosis and treatment of diseases associated with prenatal DEHP exposure.

Objective:To explore the influencing factors of major adverse cardio-cerebrovascular events(MACCE)after drug-eluting stenting in patients with coronary artery disease(CAD).Methods:Retrospective study data from First Affiliated Hospital of Zhengzhou University were extracted from the Dryad database.Patients were di-vided into MACCE group(n=160)and control group(n=880)according to whether MACCE occurred during fol-low-up.Clinical data including age,gender,fibrinogen(Fg)level etc.were compared between two groups,and the variables with significant differences between two groups were substituted into Logistic regression model to screen the influencing factors of MACCE after drug eluting stenting in CAD patients.Results:Compared with pa-tients in control group,those in MACCE group had significant higher Fg level[(3.6±1.1)g/L vs.(3.4±1.0)g/L],proportions of triple-vessel coronary disease(25.6％ vs.18.3％)and right coronary artery lesion(53.1％ vs.41.7％)(P＜0.05 or＜0.01).Multivariate Logistic regression analysis indicated that Fg level(OR=1.18,95％CI 1.01～1.37,P=0.039)was the independent risk factor of MACCE after drug eluting stenting in CAD patients.The risk of MACCE after drug eluting stenting in CAD patients significantly increased when the Fg level was＞3.27 g/L.Conclusion:High Fg level is the independent risk factor of MACCE after drug eluting stenting in CAD patients.
