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.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

OBJECTIVES: To investigate the mechanism mediating the regulatory effect of miR-155-5p on proliferation of human submandibular gland epithelial cells (HSGECs) in primary Sjogren's syndrome (pSS). METHODS: Dual luciferase reporter assay was used to verify the targeting relationship between miR-155-5p and the PI3K/AKT pathway. In a HSGEC model of pSS induced by simulation with TRAIL and INF-γ, the effects of miR-155-inhibitor-NC or miR-155 inhibitor on cell viability, cell cycle, apoptosis and proliferation were evaluated using CKK8 assay, flow cytometry and colony formation assay. ELISA and RT-PCR were used to detect the expressions of inflammatory cytokines and miR-155-5p mRNA in the cells; Western blotting was performed to detect the expressions of proteins in the PI3K/AKT signaling pathway. RESULTS: Dual luciferase assay showed that miR-155-5p targets the PI3K/AKT pathway via PIK3R1 mRNA. The HSGEC model of pSS showed significantly decreased cell viability, cell clone formation ability and expressions IL-10 and IL-4 and increased cell apoptosis, cell percentage in G2 phase, expressions of TNF‑α, IL-6, miR-155-5p and PIK3R1 mRNA, p-PI3K/PI3K ratio, p-Akt/AKT ratio, and PIK3R1 protein expression. Treatment of the cell models with miR-155 inhibitor significantly increased the cell viability, G1 phase cell percentage, colony formation ability, and expressions of IL-10 and IL-4 levels, and obviously reduced cell apoptosis rate, G2 phase cell percentage, expressions of TNF-α, IL-6, miR-155-5p and PIK3R1 mRNA, p-PI3K/PI3K ratio, p-AKT/AKT ratio, and PIK3R1 protein expression. CONCLUSIONS In HSGEC model of pSS, inhibition of miR-155-5p can promote cell proliferation and reduced cell apoptosis by targeting PI3K1 mRNA to negatively regulate the overexpression of PI3K/AKT signaling pathway.

Objective: To investigate the characteristics and trend of stroke incidence in Jining City, Shangdong Province from 2015 to 2022, so as to provide the reference for formulating prevention and control strategies of stroke. Methods: Data of stroke incidence in Jining City from 2015 to 2022 were collected from Shandong Provincial Chronic Disease Surveillance Information Management System. The crude incidence was estimated, standardized using the data of the sixth national population census in 2010, and analyzed by age, gender and subtype. The trend in incidence of stroke was analyzed using annual percent change (APC). Results: A total of 316 267 cases of stroke were reported in Jining City from 2015 to 2022, with a crude incidence of 474.17/105 and a standardized incidence of 371.43/105. The incidence of stroke peaked from March to May (90 409 cases, 28.59%). There were 278 901 cases of ischemic stroke (88.19%) and 37 366 cases of hemorrhagic stroke (11.81%). The crude incidence of stroke was higher in males than in females (525.45/105 vs. 420.16/105, P<0.05). The crude incidence of stroke increased with age (P<0.05), reaching a peak in the age group of 80 years and above (2 764.92/105). From 2015 to 2022, the crude incidence of stroke in the overall population, males, females, the age groups of 0-<30 years and 40-<50 years showed increasing trends (APC=6.142%, 6.992%, 5.054%, 3.693% and 6.587%, all P<0.05); the crude incidence of ischemic stroke in the overall population, males and females showed increasing trends (APC=7.489%, 6.593% and 5.456%, all P<0.05), while the crude incidence rates of hemorrhagic stroke did not show significant trends (APC=3.455%, 2.804% and 1.919%, all P>0.05). Conclusions The crude incidence of stroke increased in Jining City from 2015 to 2022, with ischemic stroke as the predominant subtype. March to May was the peak period for disease onset, and young and middle-aged men should be focused on.

Objective:To understand the current status of occupational exposure to dust or harmful gases and occupational protection in people aged ≥40 years in China, and provide data support for the prevention and control of occupational dust or harmful gas exposure.Methods:The data were obtained from the surveillance for chronic obstructive pulmonary disease (COPD) in adults aged ≥40 years selected by multi-stage stratified cluster sampling from 125 surveillance points in 31 provinces (autonomous regions and municipalities) during 2014-2015 and 2019-2020, and relevant information about occupational dust or harmful gas exposure and protection measures were collected through face-to-face interviews. Occupational dust or harmful gas exposure rate and occupational protection rate were estimated by using weighting complex sampling methods, and then the results were compared.Results:From 2014 to 2015 and from 2019 to 2020, a total of 71 061 and 71 023 individuals aged ≥40 years were surveyed, respectively. The rate of occupational exposure to dust or hazardous gas was 33.8% (95% CI: 29.9%-37.7%) during 2019-2020. The occupational exposure rate was higher in men than in women and in rural residents than in urban residents. With the increase of education level, the rate of occupational exposure to dust or harmful gas showed a downward trend. The protection rate against occupational dust or hazardous gas exposure was 47.9% (95% CI: 43.2%-52.6%) during 2019-2020. Compared with 2014-2015, the rate of occupational exposure to dust or hazardous gas decreased by 10.7 percentage points in different gender, area and occupational groups and the occupational protection rate increased by 21.9 percentage points during 2019-2020. The decrease in occupational exposure rate was higher in western China than in eastern and central China, and the increase in occupational protection rate was higher in western China than in eastern and central China. Conclusions:The rate of occupational exposure to dust or harmful gas decreased and the rate of occupational protection against dust or harmful gas exposure increased in China during 2019-2020. However, about one-third of the population still suffer from the occupational exposure, and less than half of them take protection measures. It is necessary to pay more attention to the key populations, such as workers with lower cultural level and rural migrant workers, in occupational health practice.

Objective:To understand the passive smoking exposure status in adults aged ≥40 years in China.Methods:Local residents aged ≥40 years were enrolled as study subjects from 125 areas of chronic obstructive pulmonary disease (COPD) surveillance during 2014-2015 and 2019-2020 in 31 provinces of China. A total of 74 559 adults aged ≥40 years were selected through multi-stage stratified cluster sampling for a face to face questionnaire survey and the data from 64 142 study subjects were used for the analysis. The passive smoking exposure rate, the proportions of the adults reporting passive smoking exposure at four types of places and the proportion of the adults living with daily smokers were described by using complicated sampling weighting method, the related factors were analyzed and the results were compared with the data of COPD surveillance during 2014-2015.Results:The passive smoking exposure rate in the adults aged ≥40 years was 46.4% (95% CI: 44.1%-48.8%) in China during 2019-2020, and the rate was higher in women (47.2%, 95% CI:44.8%-49.7%) than in men (44.8%, 95% CI:42.0%-47.6%) and lower in the older people. The office workers had the highest passive smoking exposure rate. The proportions of those reporting passive smoking exposure at homes, workplaces, restaurants, and public transports were 24.3% (95% CI:22.2%-26.4%)、23.3% (95% CI:21.1%-25.5%)、6.6% (95% CI:5.3%-7.9%) and 2.2% (95% CI:1.6%-2.7%). The higher education level the adults had, the less passive smoking exposure at home they reported. The proportions of those living with daily smokers before 14 years old and since 14 years old were 56.4% and 59.2%. Compared with the data during 2014-2015, the overall passive smoking exposure rate in the adults aged ≥40 years during 2019-2020 showed an increase, and the difference was not significant ( P=0.356); The passive smoking exposure rate at homes declined, but the exposure rate at workplaces increased, with the biggest increase found in those being engaged in farming, forestry, husbandry, fishery and water conservancy. Multivariate analysis indicated that the factors influencing the passive smoking exposure and the exposure proportions at different places included gender, age, occupation, and education level. Conclusions:The passive smoking exposure rate in China is still high, especially in those being engaged in farming, forestry, husbandry, fishery and water conservancy. It is necessary to strengthen supervision of the enforcement of current smoking bans in public places and promote the legislation of ban smoking in public places. More attention should be paid to smoking ban and protection against passive smoking exposure in women, people with lower education level and people being engaged in in farming, forestry, husbandry, fishery and water conservancy.

Objective:To analyze the exposure level and changes in severe respiratory infection among Chinese residents aged ≥40 years in China and to provide essential data for preventing and controlling chronic respiratory diseases.Methods:The data came from chronic obstructive pulmonary disease surveillance of Chinese residents in 2014-2015 and 2019-2020. The surveillance covers 31 provinces (autonomous regions and municipalities) in China. A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥40 years. Relevant information about exposure to severe respiratory infections during childhood was collected through investigation. Rigorous complex sampling and weighted analysis were applied to estimate the exposure rate of severe respiratory infections among children with different characteristics among residents aged ≥40 years in China from 2019 to 2020. Additionally, changes in severe respiratory infections during childhood were analyzed over 2014-2015 and 2019-2020.Results:In 2019-2020, the exposure rate of severe respiratory infection before 18 for residents aged ≥40 years in China was 21.58‰ (95% CI: 17.57‰-25.59‰). The exposure rate of severe respiratory infection before the age of 14 was 19.40‰ (95% CI:15.25‰-23.55‰), the difference in the exposure rate between men and women was not statistically significant (both P>0.05), and the exposure rate of urban residents is higher than that of rural residents. The results of multivariate logistic regression analysis showed that in western rural areas, factors including being born by cesarean section, exposure to secondhand smoke before age 14 years old, and a family history of chronic respiratory diseases were associated with severe respiratory infections in childhood. Compared with 2014-2015, the proportion of residents aged 40 and older in China hospitalized for pneumonia or bronchitis before 14 from 2019 to 2020 was slightly lower than five years prior. Conclusions:Among residents in China aged ≥40 years, 21.58‰ experienced severe respiratory infection exposure during childhood, varying exposure levels across different demographic groups. The burden of chronic respiratory diseases in adulthood cannot be ignored. Efforts should be made to expand the coverage of planned immunization and to focus on early-life interventions during childhood to reduce the incidence of severe respiratory infections.

Objective:To evaluate the therapeutic effect of intense pulsed light on rosacea.Methods:From December 2022 to April 2023, the Dermatology Department of the Affiliated Hospital of Shaanxi University of Chinese Medicine searched PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP, CBM and other Chinese and English databases to collect clinical randomized controlled studies on intense pulsed light treatment of rosacea for ameta-analysis.Results:A total of 559 patients were included in 6 randomized controlled trials. The efficacy of the combination of strong pulsed light and medication in the treatment of rosacea was significantly better than that of medication alone ( Z=6.15, P<0.001). After subgroup analysis, the combination of strong pulsed light and tetracycline drugs was more effective in treating rosacea than using tetracycline drugs alone ( Z=3.17, P<0.05). The efficacy of the combination of strong pulsed light and minocycline in the treatment of rosacea was better than that of minocycline alone ( Z=2.37, P<0.05), and clinical evaluation showed the improvements of erythema, papules, and pustules. The differences in scores for itching and capillary dilation were statistically significant ( P<0.05). Conclusions:The efficacy of intense pulsed light therapy for rosacea is definite, and its combination with topical or oral medication is superior to that of medication alone. However, the stability of the effect needs to be confirmed by more high-quality randomized controlled trials.

Objective To preliminary explore the in vitro anti-inflammatory effects of Qinggan Tongyin based on serum pharmacology and network pharmacology.Methods The effects of the serum containing Qinggan Tongyin on the release of NO,cell necrosis factor-α(TNF-α),and interleukin-6(IL-6)in LPS-induced RAW264.7 cells were confirmed using serum pharmacology.UHPLC-MS/MS was used to determine the index components of Qinggan Tongyin.The possible targets and pathways of active components in Qinggan Tongyin for anti-inflammatory properties were predicted by using network pharmacology.Results The results of cellular assay showed that Qinggan Tongyin could dramatically lessen the levels of NO,TNF-α,and IL-6(P＜0.05,P＜0.01,P＜0.001).The higher contents of Qinggan Tongyin were phillyrin A,arctiin,chlorogenic acid,scutellarin,gallic acid,rosmarinic acid,paeoniflorin and phillyrin.A totsl of 215 intersection targets between 17 active components in Qinggan Tongyin and inflammation were obtained,and the 31 core targets were ALB,VEGFA,IL-6,TNF-α,etc..The primary targets can exhibit anti-inflammatory actions by regulating several signaling pathways,such as AGE-RAGE,PI3K-Akt,and MAPK signaling pathway.Conclusion Qinggan Tongyin exerts its anti-inflammatory effects with the characteristic of multiple components and multiple targets.

Objective:To investigate the acute gastrointestinal injury (AGI) in patients with extracorporeal membrane oxygenation (ECMO) at the early stage of operation and its influencing factors.Methods:A total of 70 patients with ECMO who were hospitalized in the Emergency Care Unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed, and a total of 70 patients with ECMO who were hospitalized in the emergency care unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed. According to the 2012 guidelines of the European Society of Intensive Care Medicine on the classification of acute gastrointestinal injury in critically ill patients, the patients were divided into AGI group and non-AGI group. The incidence of acute gastrointestinal injury in the early stage was statistically analyzed, and the results of blood gas analysis during ECMO loading and ECMO parameters, hemodynamic indexes and biochemical indexes after ECMO transfer were statistically analyzed. To explore the influencing factors and independent risk factors of AGI in the early stage. In addition, 70 patients were divided into successful group and non-successful group according to whether they were successfully withdrawn. The occurrence of acute gastrointestinal injury between the two groups was compared, and the effect of acute gastrointestinal injury on ECMO patients was analyzed.Results:Among the 70 ECMO patients, the incidence of early AGI was 71.43% (50 cases), and the components of AGI Ⅰ, Ⅱ, Ⅲ and Ⅳ were 18.57% (13 cases), 41.43% (29 cases), 11.43% (8 cases) and 0% (0 cases), respectively. ① Univariate analysis showed that systolic blood pressure, diastolic blood pressure, mean arterial pressure (MAP), vasoactive drug index (VIS), pH, lactic acid and BMI were significantly different between AGI group and non-AGI group when ECMO was used ( P < 0.05). Logistic binary regression analysis showed that BMI was an independent risk factor for early AGI in ECMO patients (ROC area 0.657, 95% confidence interval 0.522-0.791 ( P < 0.05), and Yoden index 0.15). (3) The AGI composition ratio of the unsuccessful group was higher than that of the unsuccessful group ( P < 0.05). Conclusions:Patients with ECMO have a high incidence of AGI in the early stage, mainly occurring in grade I and Ⅱ. Systolic blood pressure, diastolic blood pressure, MAP, VIS, pH, lactic acid and BMI when ECMO is put on are influential factors for the early development of AGI in ECMO patients, among which BMI is an independent risk factor for the early development of AGI in ECMO patients. The occurrence of AGI reduces the probability of successful withdrawal in ECMO patients.
