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 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.

Objective:To investigate the recovery of renal function and its influencing factors in patients receiving extracorporeal membrane oxygenation (ECMO) support and complicated with acute kidney injury(AKI).Methods:This was a retrospective observational study. The clinical data of patients with ECMO support and AKI admitted to the Emergency intensive care unit of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2019 to December 2021 were collected. The patients were divided into renal function recovery group and renal function non-recovery group according to the recovery of renal function after 28 days of ECMO. With renal function non-recovery at 28 days as the end point of the study, and the variables with significant differences in baseline were selected for stepwise backward regression to determine the independent risk factors. The receiver operator characteristic (ROC) curve was drawn, and the area under the curve (AUC) was used to evaluate the diagnostic value of independent risk factors.Results:A total of 40 patients were enrolled, of which 28 patients (70%) had recovery of renal function, and 12 patients (30%) did not have recovery of renal function. Stepwise backward multivariate logistic regression analysis showed that lactate level at ECMO initiation was an independent risk factor for non-recovery of renal function ( OR = 1.380, 95% CI: 1.096-1.738, P = 0.006). The ROC curve showed that the AUC and 95% CI were 0.863 (0.751-0.975), the sensitivity was 100%, and the specificity was 75%. Conclusion:Lactate level at ECMO initiation was an independent risk factor for non-recovery of renal function on 28 days after ECMO initiation among patients undergoing ECMO support complicated with AKI. Lactate has a high predictive value for the non-recovery of renal function.

This study aims to analyze the main drug resistance mechanism of Salmonella enteritidis induced by polymyxin in vitro.In this study,the resistance of Salmonella enteritidis CMCC(B)50335(ZK)to polymyxin was induced in vitro,and the growth characteristics,exercise ability,ul-trastructure and sensitivity to 16 antimicrobial agents before and after induction were determined by turbidimetry,semi-solid agar method,transmission electron microscope and disk diffusion method,and the whole genome and single nucleotide polymorphism(SNP)were detected by Illu-mina NovaSeq PE150 method.RT-qPCR was used to detect the differences in the expression levels of six drug-resistant related genes.The recombinant strain △phoPE1-128-1,which induced drug-resistant strain E1-128-1,was constructed by homologous recombination of Red Escherichia coli,and its sensitivity to polymyxin was detected.The results showed that three strains of induced drug-resistant bacteria E1-128-1,E1-128-3 and E2-128-3 were screened out,and the MIC increased by 128,64 and 64 times respectively after drug resistance stability test.Induced drug resistance had no significant effect on the growth ability of the tested bacteria and the sensitivity of 16 antibacte-rial drugs.The exercise ability of E1-128-1was significantly increased,and the cell wall and plasma membrane obviously thicken.There was no significant difference in the genome components of E1-128-1 before and after induction,but eight missense mutations of six drug-resistance related genes,including phoP/phoQ,cpxP,lptD,csrA and acrB,were detected,including four missense mutation sites of phoP,namely Leu185Trp,His189Ser,Thr190Tyr and Ile191His.The corresponding genes were sequenced by PCR,and the results were consistent with those of SNP.RT-qPCR results showed that the expression levels of mutant genes of the three induced strains increased signifi-cantly.Compared with E1-128-1,the MIC of △phoP E1-128-1 decreased to 1 mg/L.It is sug-gested that the mutation and increased expression of phoP gene are important factors for inducing polymyxin resistance of Salmonella CMCC(B)50335 in vitro.

Objective To analyze the prevalence,burden and risk factors of mental disorders in Chinese population from 1990 to 2019.Methods Data on disease burden of mental disorders in China from 1990 to 2019 was obtained from the Global Burden of Disease(GBD)in 2019.The prevalence,disability adjusted of life years(DALY)and burden attributable to risk factors of mental disorders were analyzed.Joinpoint was used to estimate the annual percent change average(APC)and the annual percent change(AAPC)of DALY rate of mental disorders and analyze the trend of disease burden.Results In 2019,the prevalence of mental disorders was 11260.42/100000.Among mental disorders,depressive disorder(3519.26/100000)and anxiety disorder(3363.60/100000)had the highest prevalence.In 2019,the DALY rate of females(1564.22/100000)was higher than that of males(1294.51/100000).Depressive disorder(531.65/100000),anxiety disorder(321.60/100000)and schizophrenia(250.99/100000)had the highest DALY rates,accounting for 37.26%,22.54%and 17.59%of the total DALY rates of mental disorders respectively.From 1990 to 2019,the DALY rate of mental disorders in China increased from 1321.15/100000 to 1426.78/100000,the age-standardized DALY rate decreased with an average annual decrease of 0.19%(95%CI:-0.22%～-0.15%),and the age-standardized DALY rate of eating disorders increased the most(AAPC=1.94%,95%CI:1.85%～2.02%).The DALY rate of depressive disorder attributable to intimate partner violence was the highest in China in 2019(26.72/100000).The DALY rate of male depression attributed to childhood sexual abuse increased significantly from 1990 to 2019(AAPC=0.68%,95%CI:0.26%～1.09%).Conclusion Attention should be paid to the prevention and treatment of mental disorders,screening and intervention measures should be carried out among high risk populations,and etiological prevention should be carried out according to risk factors to reduce the burden of mental disorders.

Objective To observe the effect of immersion virtual reality (IVR) training combined with occupational therapy (OT) in the treatment of stroke patients with unilateral neglect. Methods Fifty stroke patients with unilateral neglect in Shanghai Fourth Rehabilitation Hospital were randomly divided into IVR plus OT group and OT group, with 25 cases in each group. The OT group received conventional OT for unilateral neglect, and the IVR plus OT group received IVR training and OT. Both groups were treated for 4 weeks. Before and after treatment, the Catherine Bergego Scale (CBS), line cancellation test, star cancellation test, and drawing clock test were used to evaluate unilateral neglect symptoms; the Fugl-Meyer Assessment for Upper Extremity (FMA-UE) and Barthel index (BI) were used to evaluate motor function of upper extremity and activities of daily living. Results After treatment, the results of CBS, line cancellation test, star cancellation test, drawing clock test, FMA-UE and BI scores were significantly improved when compared with those before treatment in both groups, and the improvement effects in the IVR plus OT group were significantly better than those in the OT group (P < 0.05 or P < 0.01). Conclusion IVR training combined with OT can improve unilateral neglect symptoms, motor function of affected upper extremity, and activities of daily living in stroke patients.

【Objective】 To explore the clinical features, treatment and prognosis of paraganglioma of the urinary bladder (PUB). 【Methods】 The clinical data of 41 PUB patients treated at our hospital during Sep.2012 and Sep.2022 were collected. The clinical features, surgical records, pathological reports and follow-up records were retrospectively analyzed. Patients’ survival was estimated with Kaplan-Meier estimator. The differences among groups were compared with Log-rank test. 【Results】 Among the 41 patients, 20 were male and 21 were female, with a median age of 52 years. All patients were treated with surgery, including transurethral resection of bladder tumor (TURBT) in 16 cases, partial cystectomy (PC) in 23 cases, and radical cystectomy (RC) in 2 cases. All patients were followed up for 4.0 to 125.0 months, with a median of 59.0 months. Local recurrence occurred in 5 patients, and distant metastasis occurred in 5 patients. Survival analysis showed that the 5-year overall survival (OS) rate and 5-year relapse-free survival (RFS) rate were 95.7% and 84.8%, respectively. Further analysis showed statistically significant differences in OS and RFS among groups with different maximum tumor diameters, growth patterns, and Ki-67 expressions (P<0.05). For patients with a maximum tumor diameter ≤2.8 cm, there was no significant difference in OS and RFS among different surgical groups. 【Conclusion】 PUB is rare, and a definitive diagnosis is based on pathology. In addition, the main treatment is surgery and the prognosis is good.

Objective:To investigate the value of multimodal MRI radiomics in the preoperative prediction of Fuhrman nuclear grade of clear cell renal cell carcinoma (ccRCC).Methods:A total of 129 patients with ccRCC confirmed by pathology from April 2011 to April 2021 in Third Affiliated Hospital of Soochow University were collected, and the imaging and clinicopathological data were retrospectively analyzed. All patients were divided into training set ( n=90) and validation set ( n=39) at the ratio of 7∶3 using random indicator method. According to the postoperative pathological results, Fuhrman grades Ⅰ and Ⅱ were included in the low grade group (96 cases, 65 cases in the training set and 31 cases in the validation set), and Fuhrman grades Ⅲ and Ⅳ were included in the high grade group (33 cases, 25 cases in the training set and 8 cases in the validation set). Two radiologists manually delineated regions of interest (ROI) on T 1WI, T 2WI, Dixon-water, Dixon-fat, susceptibility weighted imaging (SWI), blood oxygen level dependent (BOLD) images, and 396 texture features were extracted from each ROI. In the training set, intra-class correlation coefficient, Mann-Whitney U test, minimum redundancy maximum relevance and least absolute shrinkage and selection operator method were used to reduce the dimension of features to obtain the best texture features. The logistic regression was used to develop the multimodal radiomics model, and the receiver operating characteristic (ROC) curve was used to evaluate the effectiveness of the model in identifying high and low-grade ccRCC in training set and validation set. Results:Four SWI, one T 2WI and one BOLD texture features were selected for modeling. The areas under the ROC curve (95%CI) of the multimodal radiomics model for identifying high and low grade ccRCC in the training and validation sets were 0.859 (0.770-0.923) and 0.883 (0.740-0.964), with the specificity at 95.4% and 87.1%, the sensitivity at 68.0% and 87.5%, the accuracy at 87.8% and 87.2%, respectively. Conclusion:The multimodal MRI radiomics model based on T 2WI, SWI and BOLD images has high effectiveness in preoperative predicting Fuhrman nuclear grade of ccRCC.

Objective:To explore the application effect of the ternary linkage continuation care model based on cognitive balance theory in patients with rheumatoid arthritis (RA), and to provide a reference for the continuation care model of RA patients.Methods:The convenience sampling method was adopted. A total of 72 RA patients who were treated in Huainan First People's Hospital, Anhui Province from January to December 2020 were selected as the research objects, and they were divided into observation group and control group by random number table method with 36 cases in each group. The control group was given regular discharge guidance and health education, and the observation group was given ternary continuous care based on cognitive balance theory on the basis of the control group. The intervention time was 3 months. The fatigue state, pain catastrophe, exercise self-efficacy and hope index was evaluated by the Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire (BRAF-MDQ), the Pain Catastrophic Scale (PCS), the Self-Efficacy for Exercise Chinese version(SEE-C), and the Herth Hope Index Scale-Chinese version (HHI-C) and the results were compared between the two groups before and after the intervention.Results:There was no significant difference in the score of BRAF-MDQ, PCS, SEE-C, HHI-C before the intervention between the two groups( P>0.05). The scores of physical fatigue, life fatigue, cognitive fatigue and emotional fatigue of BRAF-MDQ in the observation group after the intervention were (10.02 ± 0.85), (6.33 ± 0.58), (3.31 ± 0.48), (4.25 ± 0.56) points, respectively, significantly lower than those in the control group (12.97 ± 1.89), (8.94 ± 0.97), (6.55 ± 0.97), (5.92 ± 0.87) points, and the differences were statistically significant ( t values were 8.54-17.96, all P<0.05). The scores of contemplation, exaggeration, and helplessness of PCS in the observation group after the intervention were (5.66 ± 0.43), (4.12 ± 0.36), (3.31 ± 0.41) points, respectively, which were significantly lower than those in the control group (8.41 ± 0.88), (5.74 ± 0.85), (5.52 ± 0.86) points, and the differences were statistically significant ( t=16.85, 10.53, 13.92, all P<0.05). The scores of SEE-C and HHI-C were (60.22 ± 7.89), (37.48 ± 5.79) points in the observation group after the intervention, which were significantly higher than those in the control group (46.98 ± 5.84), (34.21 ± 4.93) points, and the differences were statistically significant ( t=8.09, 2.58, both P<0.05). Conclusions:The ternary linkage continuation nursing model based on the cognitive balance theory has a significant effect on alleviating the fatigue state and pain catastrophe of RA patients, and helps to improve the patients' hope level and exercise self-efficacy.
