OBJECTIVE To explore optimization pathways for the drug traceability code management model in outpatient pharmacy workflows， providing practical evidence for enhancing the efficiency of pharmaceutical service. METHODS Taking the outpatient pharmacy of the First Affiliated Hospital of Sun Yat-sen University as the research subject， a comprehensive drug traceability system was established through three key interventions： upgrading the information system architecture [including integration of the hospital information system （HIS） with the traceability platform]， workflow optimization （reorganizing the inventory-dispensing-verification tripartite process）， and designing a dual-mode traceability data collection mechanism （primary data capture at dispensing stations and supplementary capture at verification stations）. Operational efficiency differences before and after implementation were analyzed using the medical insurance data and service timeliness metrics in September 2024. RESULTS After the implementation of drug traceability code management， in terms of data collection: Mode Ⅰ （verification-stage capture） uploaded 26 144 records， while Mode Ⅲ （inventory-as-sales capture） uploaded 443 061 records， totaling 469 205 entries； in terms of time efficiency： average drug dispensing time increased from 28.74 s to 43.37 s （enhanced by 51%）. Through dynamic staffing adjustments， patient wait time only extended from 8.04 min to 8.67 min （enhanced by 8%）. CONCLUSIONS Drug traceability code management can be effectively implemented via a “system reconstruction-process reengineering-human-machine collaboration” trinity strategy， leveraging informatization （e.g.， dual-mode data capture） to offset manual operation delays， which validates the feasibility of balancing national traceability demands with service efficiency in outpatient pharmacies.

Objective To investigate the serum micro-ribonucleic acid-15a(miR-15a)and macrophage mi-gration inhibitory factor(MIF)levels and their relationship with adverse maternal and infant outcomes in pa-tients with gestational diabetes mellitus(GDM).Methods From January 2020 to December 2022,106 patients with GDM who underwent prenatal examination and gave birth in the Hengshui Fourth People's Hospital were selected as the experimental group.Another 106 healthy women who underwent pregnancy examination and delivered in a hospital during the same period were selected as the control group.Detection of serum miR-15a level by real-time fluorescent quantitative polymerase chain reaction and serum MIF levels were detected by enzyme-linked immunosorbent assay.Serum MIF and miR-15a levels were compared between the two groups,and the relationship between miR-15a and MIF levels and adverse maternal and infant outcomes in GDM patients was analyzed by multivariate Logistic regression.Results The serum levels of miR-15a and MIF in the experimental group were higher than those in the control group,the difference was statistically sig-nificant(P＜0.05).The age of patients with adverse maternal and infant outcomes in the experimental group was＞35 years old,the pre-pregnancy body mass index was＞24 kg/m2,the proportion of patients with ad-verse pregnancy history,poor blood glucose control and serum MIF and miR-15a levels were higher than those with good maternal and infant outcomes in the experimental group,and the differences were statistically sig-nificant(P＜0.05).Multivariate Logistic regression analysis showed that age＞35 years old,pre-pregnancy body mass index＞24 kg/m2,adverse pregnancy history,poor blood glucose control and serum miR-15a and MIF were all risk factors for adverse maternal and infant outcomes in the experimental group(P＜0.05).Conclusion Serum miR-15a and MIF levels are abnormally elevated in GDM patients,and serum miR-15a and MIF levels are closely related to adverse maternal and infant outcomes.

Objective To study the changes in serum immunoglobulin levels in children with thalassemia who undergo repeated blood transfusions and explore their correlation with delayed hemolytic transfusion reactions(DHTR).Methods Serum samples from children with thalassemia who received blood transfusion treatment from June 2022 to April 2023(ob-servation group)and healthy children who underwent physical examination(control group)in our hospital were collected.The levels of serum immunoglobulins(IgG subtype,IgM,IgA,IgE and IgD)were detected using flow cytometry CBA multi-factor quantitative detection technology,and the differences between the two groups were compared.The children were divided into 4 groups according to different transfusion numbers:≤10 numbers,11-30 numbers,31-50 numbers and＞50 numbers,and the differences between different blood transfusion numbers and serum immunoglobulin levels in each group were compared using one-way analysis of variance(ANOVA).Children with thalassemia with DHTR were in the hemolysis group,and children with thalassemia who did not experience DHTR were in the non-hemolysis group.The changes in serum immunoglobulins(IgG subtypes,IgM,IgA,IgE and IgD)between the two groups were compared to explore the correlation between serum immunoglobulins in thalassemia children with repeated transfusion and DHTR.Results The levels of IgG1,IgG3,IgG4 and IgA in the observation group were significantly higher than those in the control group,with the increase of(2.07±2.12),(0.67±2.03),(0.30±0.37)and(6.04±11.40)mg/mL,respectively,while the level of IgD in observation group was significantly lower than that in the control group,with a decrease of(0.03±0.01)mg/mL,P＜0.05.No significant difference was noticed in IgG2,IgM and IgE between the groups(P＞0.05).IgG1 and IgG4 both significantly increased with the number of blood transfusions.The IgG1 in the 4 groups increased sequentially as(0.30±0.62),(0.41±0.51)and(3.60±3.48)mg/mL,and IgG4 increased sequentially as(0.12±0.13),(0.22±0.07)and(0.21±0.38)mg/mL.IgG2,IgM and IgD showed a significant decrease,with IgG 2,IgM,and IgD in four groups decreased as(0.91±1.50),(0.14±0.10)and(0.05±0.05)mg/mL,respectively,showing significant differences with the number of blood transfusions(P＜0.05).No sig-nificant difference was found in IgG3,IgA and IgE with different number of transfusions(P＞0.05).IgG1,IgG3 and IgG4 in the hemolysis group were significantly higher than those in the non-hemolysis group,with an increase of(4.44±3.41),(0.73±1.26)and(0.52±0.40),respectively(P＜0.05).IgD in the hemolysis group was significantly lower than that in the non-hemolysis group,with a decrease of(0.00±0.06)mg/mL,P＜0.05.No significance was noticed in IgG2,IgM,IgA and IgE between the hemolysis group and the non-hemolysis group(P＞0.05).Conclusion The serum immunoglobulin levels of children with thalassemia who undergo repeated blood transfusions are abnormal.There are differences in correlation between the number of blood transfusions and serum immunoglobulin levels among children with thalassemia who undergo repeated blood transfusions.The relevant serum immunoglobulins for DHTR in children with thalassemia who undergo repeated blood transfusions are IgG1,IgG3 and IgG4.

Objective:To systemically evaluate the characteristics of cytokine levels in intraocular fluid of neovascular glaucoma (NVG).Methods:Literature on the detection of cytokine levels in NVG published before June 2022 was searched in PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang databases, and China Science and Technology Journal Database (VIP).Two investigators independently completed the literature search, inclusion, and data extraction following the inclusion and exclusion criteria.Quantitative analyses were performed using Stata 16.0 software.Study heterogeneity was assessed using the I2 test, and effects were combined using the appropriate effect model to complete the meta-analysis. Results:A total of 24 studies were screened, including 771 NVG cases and 727 age-related cataract cases (control group).The standardized mean difference ( SMD) of the combined effect value of vascular endothelial growth factor (VEGF) mass concentration in the aqueous humor between the two groups was 8.79, with a 95% confidence interval ( CI) of 6.43 to 11.14.The SMD of interleukin-6 (IL-6) between the two groups was 12.50, with a 95% CI of 9.41 to 15.58.The VEGF and IL-6 levels in aqueous humor and vitreous humor were significantly higher in NVG group than in control group (all at P<0.05).The pigment epithelium-derived factor (PEDF) level in aqueous humor was lower in NVG group than in control group ( SMD: -3.03, 95% CI: -5.50--0.55, P<0.05).The levels of IL-8 ( SMD: 3.99, 95% CI: 1.14-6.85), erythropoietin (EPO) ( SMD: 9.62, 95% CI: 0.44-18.79), placental growth factor (PIGF) ( SMD: 2.62, 95% CI: 1.38-3.86), tumor necrosis factor-α (TNF-α) ( SMD: 3.37, 95% CI: 1.87-4.87) were all significantly higher in NVG group than in control group (all at P<0.05).There was no significant difference in IL-1β level in aqueous humor between the two groups ( P>0.05). Conclusions:In NVG patients, VEGF, IL-6, IL-8, EPO, PIGF, TNF-α levels are obviously increased and PEDF level is obviously decreased.These biomarkers can be used as potential predictors or therapeutic targets for NVG.

OBJECTIVE To study the protective effects of ligustrazine-scutellarein twin drug ST-11 on rat adrenal medullary pheochromocytoma PC12 cell injury induced by oxygen-glucose deprivation/reperfusion （OGD/R） and its mechanism. METHODS PC12 cells were divided into blank group， model group， nimodipine group （positive control， 5 μmol/L） and different concentration groups of ST-11 （5， 10， 20 μmol/L）. After 24 hours of pre-administration intervention， all the other groups except the blank group were cultured in glucose-free DMEM culture medium containing 10 mmol/L Na2S2O4 for 4 hours with glucose deficiency and hypoxia. After 4 hours of glucose and oxygen re-introduction， the survival rate of cells in each group， the contents of lactate dehydrogenase （LDH）， catalase （CAT）， glutathione （GSH）， malondialdehyde （MDA） and superoxide dismutase （SOD） in cell supernatant， apoptosis rate， the levels of reactive oxygen species （ROS） and mitochondrial membrane potential （MMP）， the protein expressions of B-cell lymphoma 2 related X protein （Bax）， B-cell lymphoma 2 （Bcl-2） and caspase-3 were all detected in each group. RESULTS Compared with blank group， the cell survival rate， the contents of CAT， GSH and SOD in cell supernatant， MMP level， relative expression of Bcl-2 and Bcl-2/Bax ratio in model group decreased significantly （P＜0.05）， while the contents of LDH and MDA， ROS level， apoptosis rate， relative expressions of Bax and caspase-3 were significantly increased （P＜0.05）. Compared with model group， above indexes of ST-11 groups （except for the protein expression of caspase-3 in 5 μmol/L ST-11 group） were reversed signifi-cantly （P＜0.05）. CONCLUSIONS ST-11 has a certain protec-tive effect on OGD/R-injured PC12 cells， and its effects may be related to reduction of oxidative stress and inhibition of cell apoptosis.

The incidence rate of anxiety and depression is significantly higher in patients with inflammatory bowel diseases (IBD) than in the general population. The mechanisms underlying dextran sulfate sodium (DSS)-induced depressive-like behaviors are still unclear. We clarified that IBD mice induced by repeated administration of DSS presented depressive-like behaviors. The paraventricular thalamic nucleus (PVT) was regarded as the activated brain region by the number of c-fos-labeled neurons. RNA-sequencing analysis showed that lipocalin 2 (Lcn2) was upregulated in the PVT of mice with DSS-induced depressive behaviors. Upregulating Lcn2 from neuronal activity induced dendritic spine loss and the secreted protein induced chemokine expression and subsequently contributed to microglial activation leading to blood-brain barrier permeability. Moreover, Lcn2 silencing in the PVT alleviated the DSS-induced depressive-like behaviors. The present study demonstrated that elevated Lcn2 in the PVT is a critical factor for DSS-induced depressive behaviors.

【Objective】 To investigate the changes in cellular immunity (peripheral blood lymphocyte subsets) and humoral immunity (serum immunoglobulin and ferritin) status among children with thalassemia who received repeated transfusions in Yunnan. 【Methods】 Forty-six children with thalassemia who underwent repeated blood transfusions from January 2020 to October 2022 were selected as the observation group. Forty children with thalassemia who did not receive blood transfusion were included in control group 1, and 46 healthy children underwent physical examination were included in control group 2. The differences in lymphocyte subsets, serum immunoglobulin levels and ferritin concentrations were compared among the three groups. 【Results】 For lymphocyte subsets: CD3⁺, CD4⁺ and CD4⁺/CD8⁺ in the observation group was lower than the control group 1 and 2: 57.60±8.36 vs 64.57±7.56 vs 66.58±5.65, 33.16±5.67 vs 38.62±8.36 vs 38.62±6.41 and 1.49±0.09 vs 2.32±0.15 vs 2.13±0.16, respectively; CD16⁺ CD56⁺ in the observation group was lower than the control group 2: 11.21±5.06 vs 16.70±7.92; CD8⁺ in the observation group was higher than control group 1 and control group 2: 26.63± 1.75 vs 20.60±1.43 vs 18.92±0.84; CD19⁺ in the observation group was higher than the control group 2: 24.06±6.42 vs 19.67 ±8.42, P<0.05, but no significant difference was noticed between the two control groups(P>0.05). For serum immunoglobulin and ferritin: IgG and ferritin in the observation group were higher than control group 1 and control group 2: 10.59±3.88 vs 7.02±3.88 vs 5.58±1.98 and 2 037.37±1 377.59 vs 72.63±56.71 vs 59.48±33.88. IgA in the observation group was higher than the control group 2: 1.06±0.92 vs 0.39±0.32(P<0.05), but no significant difference was noticed between the two control groups (P>0.05). The difference of IgM and IgE between the three groups was not significant (P > 0. 05). 【Conclusion】 The proportion of lymphocyte subsets in thalassemia children with repeated blood transfusion was imbalanced,and the level of immunoglobulin in humoral immunity was abnormal.

Objective: To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD. Methods: Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model. Results: A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD. Conclusions Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.
