OBJECTIVE To explore the transformation of the dispensing and drug pickup process in traditional Chinese medicine pharmacy （TCM Pharmacy） in our hospital based on data-intelligence-driven， aiming to improve pharmacists’ work efficiency and patients’ drug pickup experience. METHODS Value stream mapping and journey mapping were used to systematically identify non-value-added links in pharmacists’ dispensing process and key pain points in patients’ drug pickup under the traditional process. An intelligent dispensing and drug pickup system for the TCM Pharmacy was developed based on the C# and Android television platforms， and a machine-learning model was adopted to predict patients’ drug pickup waiting time. A comprehensive evaluation was performed from three perspectives： system performance， prediction accuracy， and satisfaction of pharmacists and patients. RESULTS The system successfully streamlined non-value-added links such as “waiting for writing on the board” and “searching for drugs”， and realized multimodal dynamic prompts of dispensing status through auditory （number calling） and visual （television terminal） channels. The constructed model for predicting drug pickup waiting time exhibited good fitting degree and generalization ability （mean absolute error＝4.28 min， R 2 ＝0.882）. The comprehensive satisfaction scores of pharmacists and patients in the traditional mode were significantly increased from （70.99±1.74） and （73.58±1.98） to （90.02±1.30） and （88.61±2.08） in the new system， respectively （ P ＜0.01）. CONCLUSIONS The transformation of the intelligent drug dispensing and pickup system for TCM pharmacy based on data-intelligence-driven effectively improves the efficiency of pharmacists’ dispensing work， realizes process transparency and waiting time predictability， and significantly enhances patients’ drug pickup experience.

Objective This study aims to investigate and analyze the distribution of MN blood type among ethnic minorities in China. Methods Through a systematic retrieval of the 981 literature related to MN blood group distribution, 120 literature, meeting the criteria of this study, with complete data were selected. The literature covers 49 ethnic minorities. SPSS 26 statistical software was used to analyze the data. Results The results showed that among the 49 ethnic minorities in China, the phenotype distribution of MN blood type was MN>MM>NN, with proportions of 42.54%, 41.86%, and 15.06% respectively. The gene frequency for MN blood type exhibited a trend of m>n, with a gene frequency of m being 0.6313 and n being 0.3687. Cluster analysis divided the Chinese ethnic minorities into three groups based on the gene frequency for m, showing the characteristics of Group I>Group II>Group III. Conclusion The MN blood type characteristics in Chinese ethnic minorities show a higher frequency of the M gene compared to the N gene. The frequency of the M gene is higher in southern ethnic minorities than in northern ones. There are significant differences between southwestern ethnic minorities and the Han nationality, but no differences with long-term mixed/settled Han populations.

Objective To evaluate the clinical efficacy of Targeted Ⅱ Formula(composed of Astragali Radix,Pseudostellariae Radix,Ophiopogonis Radix,Asparagi Radix,Glehniae Radix,Rehmanniae Radix,Ligustri Lucidi Fructus,Ecliptae Herba,Polygonati Rhizoma,Polygonati Odorati Rhizoma,etc.)in delaying epidermal growth factor receptor(EGFR)tyrosine kinase inhibitors(TKIs)resistance in EGFR mutation-positive non-small cell lung cancer(NSCLC)patients with.Methods Between January 1,2019 and June 30,2023,64 NSCLC patients with qi-yin deficiency syndrome treated at Shanghai Pulmonary Hospital(affiliated to Tongji University)were stratified based on their 1-month post-targeted therapy response and then were randomized into a treatment group(receiving Icotinib plus Targeted Ⅱ Formula decoction)or a control group(receiving Icotinib alone).Patients were followed-up until disease progression.Progression-free survival(PFS),adverse events,quality of life,and immune function were assessed.Results(1)In terms of PFS,the mean PFS in the treatment group was(18.78±7.17)months,while that in the control group was(11.76±4.26)months.The PFS in the treatment group was significantly longer than that in the control group,with a statistically significant difference(P＜0.001);the 1-year PFS rate in the treatment group was 87.50％(28/32),significantly higher than the 38.71％(12/31)in the control group,with a statistically significant difference(P＜0.001).(2)In terms of adverse reactions,the incidence of targeted drug-related rash in the treatment group was 68.75％(22/32),lower than that of the control group(80.65％,25/31),but the difference between the two groups was not statistically significant(P＞0.05).In terms of rash grading,both groups primarily had Grade 1 rashes,and the treatment group had fewer Grade 2 and 3 rashes than the control group,indicating that the severity of rashes was more pronounced in the control group.(3)In terms of quality of life,after treatment,the Karnofsky Performance Status(KPS)score in the treatment group significantly increased compared to before treatment(P＜0.05),while the control group showed no significant increase compared to before treatment(P＞0.05).The intergroup comparison revealed that the increase of KPS scores in the treatment group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)In terms of immune function,after treatment,the levels of CD8+T lymphocytes and interferon-γ(IFN-γ)in peripheral blood were significantly higher in the treatment group than before treatment(P＜0.05),while those in the control group were significantly lower than before treatment(P＜0.05);Intergroup comparisons revealed that the treatment group exhibited a significantly greater reduction in peripheral blood CD8+T lymphocyte and IFN-γ expression levels compared to the control group,with statistically significant differences(P＜0.05).Conclusion This study employed an innovative stratified randomization design to eliminate bias in Icotinib efficacy.The results demonstrate that Targeted Ⅱ Formula effectively delays EGFR-TKI resistance,mitigates adverse events,and improves quality of life in EGFR mutation-positive NSCLC patients with qi-yin deficiency syndrome,supporting its role as an adjuvant therapy in targeted lung cancer treatment.

Acute kidney injury（AKI）is one of the risk factors leading to death in premature infants.The incidence of AKI showed a upward trend year by year.The pathogenesis may be related to preterm birth with insufficient nephrons，prenatal inflammatory injury and urinary podocyte loss.The occurrence rate of AKI in premature infants increased with the decreasing of gestational age and birth weight.It should be emphasized that AKI in premature infants does not exist independently，but interacts with other organs，such as heart，lung，intestine，brain，and other organs.Moreover，the involvement of these organs may increase the risk of AKI，and so does bloodstream infections.Blood creatinine and urine volume can be used for clinical diagnosis and classification of AKI in premature infants.Glucocorticoids and caffeine can protect kidney in premature infants.Due to the lack of specificity in the treatment of AKI，fluid management and medication are important for the development of AKI.Renal replacement therapy，the common of which are peritoneal dialysis and continuous renal replacement therapy，can be used in severe AKI.

Objective:To construct machine learning-based delirium prediction models for ICU patients with multiple trauma and evaluate their prediction efficiency.Methods:A retrospective case-control study was conducted to analyze the clinical data of 417 ICU multiple trauma patients admitted to the First Affiliated Hospital of Zhengzhou University from July 2019 to June 2022, including 305 males and 112 females, aged 18-88 years [(47.8±15.7)years]. The score of acute physiology and chronic health status assessment II (APACHE II) was 0-50 points [(9.80±0.29)points]. The patients were randomly divided into training set ( n=291) and test set ( n=126) with a ratio of 7∶3. The demographic data, past history, treatment and laboratory results of the patients were collected. Lasso regression analysis was applied to screen variables that were significantly correlated to the incidence of delirium in the training set and the variables were then included into the machine learning models. Six machine learning methods including the random forest, gradient boosting tree, extreme gradient boosting, logistic regression, support vector machine and K nearest neighbor were used to construct the delirium prediction models for ICU multiple trauma patients. The accuracy, sensitivity, precision, F1 fraction and area under the curve (AUC) of the receiver′s operating characteristics (ROC) curve were calculated by using the data in the test set to evaluate the prediction efficiency of the models. Results:With regards to the six prediction models, namely random forests, gradient boosting tree, extreme gradient boosting, logistic regression, support vector machine and K nearest neighbor prediction models, the accuracy in the test set was 0.70, 0.68, 0.69, 0.73, 0.70 and 0.60 respectively; the sensitivity was 0.74, 0.80, 0.81, 0.86, 0.85 and 0.69 respectively; the precision was 0.72, 0.69, 0.70, 0.73, 0.71 and 0.65 respectively; the F1 fraction was 0.73, 0.74, 0.75, 0.79, 0.78 and 0.67 respectively; the AUC was 0.72, 0.73, 0.72, 0.80, 0.74 and 0.64 respectively. Among them, the logistic regression model had the best discriminability.Conclusion:Delirium prediction models for ICU patients with multiple trauma have been successfully constructed, among which the logistic regression model has the best prediction efficiency and can serve as an effective tool for early prediction and prevention of delirium in the clinical care of patients with multiple trauma.

Objective:To explore the clinical efficacy of chemoembolization with doxorubicin-infused gelatin sponge microparticles in the amelioration of arterioportal shunting (APS) in patients afflicted with hepatocellular carcinoma (HCC).Methods:A retrospective investigation was conducted on 9 HCC patients admitted between January 2020 and December 2022 with concomitant moderate-to-severe APS who underwent GSM-transarterial chemoembolization (TACE). Hepatic artery digital subtraction angiography (DSA) was employed to ascertain the magnitude of improvement in arteriovenous shunts, utilization of modified response evaluation criteria in solid tumors facilitated the appraisal of short-term clinical outcomes. Follow-up records documented survival duration, along with quantitative parameters such as the longest diameter of tumor lesions and serum alpha-fetoprotein (AFP) levels before and after treatment. The Wilcoxon rank-sum test was utilized to compare the differences of these quantitative parameters before and after treatment.Results:The APS amelioration rates were 100% and 88.9% at immediate and recent postoperatively, respectively. The oncological response rate was 77.8% (7/9), and the complete necrosis rate was 22.2% (2/9) at three months postoperatively, the 1-year survival rate was 100%. Following treatment, a significant reduction was observed in the tumor′s longitudinal diameter [4.32(3.88,6.63)cm] and serum AFP levels [13.50 (7.55, 29.60) μg/L], compared to the pre-treatment values of the tumor′s longitudinal diameter [5.20(4.58,8.57)cm] and serum AFP levels [524.30 (320.65, 1 046.15) μg/L] ( P<0.05 for all). Conclusion:Doxorubicin-infused GSM-TACE is both feasible and efficacious in the first treatment of HCC concomitant with APS and represents a better clinical alternative.

Objective To investigate the factors involved in the development of thyroid nodules and the correlation between homocysteine(Hcy)and albumin-globulin ratio(AGR)and thyroid autoantibodies in adults.Methods As a retrospective study,a total of 1 427 people who received physical examination at the Second Hospital Affilia-ted to Hebei North College from October 2019 to August 2020 and the clinical data of the subjects who fulfilled the criteria of NAR were selected for analysis by simple random sampling.All of subjects underwent thyroid color ultrasound scanning and were divided into a control group(without thyroid nodules,n=52)and an observation group(with thyroid nodules,n=48).The general clinical data of the two study groups were compared,and the correlation between Hey and AGR and thyroid autoantibodies was analyzed.Confunding factors affecting the inci-dence of thyroid nodules were screened using multifactorial unconditional logistic regression analysis.Results The observation group showed statistically significant differences in gender,age,diastolic blood pressure,systolic blood pressure,Hey,AGR,TGAb,and TPOAb as compared to the control group(P＜0.05);Using adult Hcy as the dependent variable and Spearman's correlation analysis of AGR,TGAb and TPOAb,adult Hcy was nega-tively correlated with AGR(r=-0.384,P＜0.05)and TGAb and TPOAb were positively correlated(r=0.218,0.224,P＜0.05);Using age,sex,diastolic blood pressure,systolic blood pressure,Hcy,AGR TGAb and TPOAb as independent variables and thyroid nodules as dependent variables,a multifactor logistic regression analysis was performed in 100 subjects who experienced physical check.The analysis showed that age ≥40 years and female were relevant factors for the development of thyroid nodules factors(P＜0.05),Hcy,AGR,TGAb and TPOAb were correlated with thyroid nodules(P＜0.05).Conclusions Thyroid nodules are more common in middle-aged women,and there is a correlation between Hcy,AGR,TGAb,and TPOAb levels and thyroid nod-ules.Regular thyroid screening examination should be carried out based on the above indicators.

Objective To investigate the relationship between circKIF4A expression and clinicopathologic features and prognosis of thyroid cancer patients.Methods A total of 120 patients diagnosed with thyroid cancer in our hospital from April 2016 to April 2017 were selected by random sampling method.Cancer tissues and adjacent tissues were taken during surgery and divided into thyroid cancer group and adjacent cancer group according to surgical pathologic detection.The relative expression level of circKIF4A in thyroid cancer group and paracancer group was detected by qRT-PCR,and the relationship between circKIF4A expression and clini-copathological features of thyroid cancer was analyzed.Kaplan-Meier survival curve was used to analyze the relationship between circKIF4A expression and prognosis of thyroid cancer patients.Cox regression analysis was performed to analyze the factors influencing the poor prognosis of patients with thyroid cancer 5 years af-ter surgery.Results The relative expression level of circKIF4A in thyroid cancer group was higher than that in paracancer group,and the difference was statistically significant(P＜0.05).The expression of circKIF4A was correlated with the degree of capsule invasion,lymph node metastasis and differentiation(P＜0.05).Kap-lan-Meier survival curve analysis showed that the 5-year cumulative survival rate of patients with high cir-cKIF4A expression was lower than those with low circKIF4A expression,and the difference was statistically significant(x2=11.368,P=0.001).Multivariate analysis showed that envelope invasion,degree of differenti-ation,lymph node metastasis and circKIF4A expression level were the influencing factors for poor prognosis of thyroid cancer patients at 5 years after surgery(P＜0.05).Conclusion circKIF4A is highly expressed in thy-roid cancer tissues,which is related to the clinicopathological features and 5-year postoperative survival of thy-roid cancer patients,and may be used as a potential prognostic marker for thyroid cancer.

Objective:To screen genetic and epigenetic expression differences associated with pulmonary embolism through integrated bioinformatics analysis.Methods:Four patients with pulmonary embolism and healthy physical examination in the Third Affiliated Hospital of Xinjiang Medical University in 2019 were selected as the research objects, using high-throughput sequencing technologies and methylation chip technology to detect, screening and integrated peripheral blood difference genomes and the epigenome data to identify the pathogenesis of pulmonary embolism caused by methylation of drive and differentially expressed genes, GO and KEGG enrichment analysis were performed.Results:Coexpression analysis of DNA methylation and gene expression data between the pulmonary embolism group and the healthy control group showed that differential methylation in the upstream region of genes was negatively correlated with gene expression. Among them, 8 significantly methylated genes in the upstream region of genes were screened out, and independent sample t-test and Pearson correlation analysis were done. In the pulmonary embolism group, there were 6 significant methylated genes of TSS1500, namely TSPO2, C1QA, AQP1, TNFSF9, MIA and STAB1, and the differential expression multiple log2FC of corresponding genes was 1.298, 1.629, 1.024, 2.746, 2.539, 1.060, respectively. The correlation between gene expression and gene methylation were -0.908, -0.900, -0.824, -0.784, -0.783, -0.779, respectively, and the methylation differences between the two groups were -0.049, -0.053, -0.048, -0.057, -0.050, respectively. -0.053 ( P < 0.05). There were three significantly methylated genes in the TSS200 region, namely TSPO2, SLC9A, and SIGLEC1. The gene expression differential multiple log2FC was 1.298, -2.252, and 1.866, respectively. The correlation between gene expression and gene methylation was -0.860, -0.774, and -0.739, respectively. The methylation difference between the two groups was -0.051, 0.027, -0.048 ( P < 0.05). In the pulmonary embolism group, 7 genes, including TSPO2, C1QA, AQP1, TNFSF9, MIA, STAB1 and SIGLEC1, showed hypomethylation and high expression in the TSS region. SLC9A3 gene showed high methylation and low expression. In the analysis of GO function, significant enrichment was obtained in complement activation, immune response and activation protein cascade. In the KEGG signaling pathway, the immune system, bacterial infection, and signaling molecules and interactions are significantly enriched, thereby regulating the occurrence of pulmonary embolism. Conclusions:Based on the combined analysis of DNA methylation and gene expression, a new idea of the occurrence and development of pulmonary embolism has been found, which can be further studied in the future.
