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.

ObjectiveTo investigate the effect and potential mechanism of caffeic acid （CA） on severe acute pancreatitis （SAP） induced by caerulein combined with lipopolysaccharide （LPS）， and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice， aged 6 weeks， were divided into control group， model group， CA group， and octreotide acetate （OA） group， with 6 mice in each group. The mice in the control group were given injection of normal saline， and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein， the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling， and serum， pancreas， lung， and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs， and the serum levels of α-amylase， lipase， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， alanine aminotransferase， aspartate aminotransferase， and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs； myeloperoxidase （MPO） immunohistochemistry was used to observe the degree of neutrophil infiltration； Western blot was used to measure the activation of nuclear factor-kappa B （NF-κB） and the level of citrullinated histone H3 （CitH3）， a marker for the formation of neutrophil extracellular traps （NETs）， in the pancreas and lungs， as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group， the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6， interleukin-1β （IL-1β）， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant increases in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. Compared with the model group， the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6， IL-1β， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant reductions in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice， possibly by inhibiting neutrophil recruitment and the formation of NETs.

The rich club, as a community of highly interconnected nodes, serves as the topological center of the network. However, the similarities and differences in how the rich club supports functional integration and segregation in the brain across different species remain unknown. In this study, we first detected and validated the rich club in the structural networks of mouse, monkey, and human brains using neuronal tracing or diffusion magnetic resonance imaging data. Further, we assessed the role of rich clubs in functional integration, segregation, and balance using quantitative metrics. Our results indicate that the presence of a rich club facilitates whole-brain functional integration in all three species, with the functional networks of higher species exhibiting greater integration. These findings are expected to help to understand the relationship between brain structure and function from the perspective of brain evolution.

Heatstroke, a life-threatening illness, poses a significant risk to human health, particularly in high-temperature and high-humidity environments. Timely and effective on-site management is critical for improving patient survival and prognosis. Rapid recognition, rapid assessment, and rapid cooling are the cornerstones of pre-hospital care. However, the absence of a standardized protocol for pre-hospital management of heatstroke has impeded the efficacy of treatment. This consensus, initiated by the Expert Group on Heatstroke Prevention of the People's Liberation Army, signifies a collaborative endeavor involving emergency medical personnel, nurses, and administrators from pre-hospital care, emergency departments, and intensive care units in both military and civilian domains. By systematically reviewing evidence-based medicine and clinical expertise in heatstroke prevention, on-site and in-transit care, as well as early treatment in emergency settings, the group has formulated the Expert consensus on pre-hospital emergency management of heatstroke (2024) after extensive discussions and iterative recommendations, which serve as a scientific and standardized framework for pre-hospital heatstroke emergency care. The consensus underscores the pivotal role of enhancing public awareness regarding heatstroke prevention and augmenting the rates of rapid recognition and rapid cooling for effective on-site heatstroke management. In high-risk industries, regions, or seasons for heatstroke, developing scientifically sound plans and conducting practical training can provide effective safety measures. Emergency personnel should undergo specialized training and assessments in knowledge and skills, ambulances should be equipped with effective cooling devices, and hospitals must maintain comprehensive emergency response capabilities. It is recommended to establish a regional heatstroke treatment network to optimize the allocation of emergency resources and streamline processes, thereby improving treatment outcomes and response times.

Objective To study the effect of the transbrachial artery approach on the success rate of puncture,revascularization time,and postprocedural complications in patients with acute ST-segment elevation myocardial infarction(STEMI)treated by percutaneous coronary intervention(PCI).Methods The clinical data of 324 patients with STEMI who underwent PCI between September 2020 and May 2024 at our hospital were retrospectively analyzed.According to the different approaches,the patients were divided into a brachial artery group(127 cases)and a radial artery group(197 cases).Their procedural parameters(X-ray exposure time,contrast agent dosage,puncture time,puncture success rate,and revascularization time)and hospital length-of-stay,cardiac function indicators,including left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS),left ventricular end-systolic volume index(LVESVI),and left ventricular end-diastolic volume index(LVEDVI),before surgery and 3 months after PCI,and the incidence of complications were compared between the two groups of patients.Furthermore,a difference-in-differences method was adopted for the logistic model to evaluate the effects of different approaches.Results There were no statistical differences in the general data between the brachial artery group and the radial artery group.Compared with those of the radial artery group,the revascularization time and length-of-stay of the brachial artery group were shortened,and the success rate of puncture was increased(P<0.05).There were no significant differences in X-ray exposure time or contrast agent dosage between the two groups.The changes in LVEF,LVFS,LVESVI,and LVEDVI from baseline to 3 months post-PCI were(10.97±7.15)%,(3.29±5.90)%,(22.11±9.30)mL/m2,and(18.13±6.68)mL/m2,respectively,in the brachial artery group,while those in the radial artery group were(10.61±7.13)%,(4.38±6.04)%,(23.13±9.60)mL/m2,and(19.34±7.27)mL/m2,respectively,without statistical differences.Difference-in-differences analysis revealed that there were no statistical differences in the effects of different approaches on LVEF,LVFS,LVESVI,and LVEDVI between the brachial artery group and the radial artery group.During follow-up,no complications,such as coronary perforation,coronary dissection,or stent thrombosis,were observed in either group,and there were no statistical differences in the complication incidence between the two groups.Conclusion The transbrachial artery approach can shorten the revascularization time and length-of-stay of patients with STEMI treated by PCI.It has a high success rate of puncture and can promote the recovery of postoperative cardiac function without increasing postoperative complications.

Objective:To analyze the specific immunoglobulin G (IgG) antibodies level in the population after the coronavirus disease 2019 (COVID-19) pandemic in Henan Province.Methods:A total of 5 178 peripheral venous blood samples were collected from 10 districts (counties) in Henan Province according to the national seroepidemiological survey program for COVID-19, and the method of cluster random sampling was adopted from March 6 to 15, 2023. Descriptive analysis was used for the basic data, history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, SARS-CoV-2 infection of the respondents. The specific IgG antibody of SARS-CoV-2 was detected using chemiluminescence method. Statistical analysis was performed by using rank sum test, Kruskal Wallis test, and Dunn′s test.Results:The overall positive rate of SARS-CoV-2-specific IgG antibody was 83.35%(4 316/5 178). There were statistically significant differences in the specific IgG antibodies against SARS-CoV-2 produced by people of different sexes, different ages, infected or not, vaccinated or not, and vaccinated with different doses of SARS-CoV-2 vaccine ( Z=3.60, H=195.32, Z=6.10, 18.08, H=382.70, respectively, all P<0.001). The specific IgG antibodies produced by unvaccinated+ uninfected group, unvaccinated+ infected group, vaccinated+ uninfected group, and vaccinated+ infected group were 3.54(0.98, 11.00), 60.65(2.33, 84.80), 133.00(59.80, 173.00), and 142.00(98.30, 176.00), respectively. And the difference was statistically significant( H=354.62, P<0.001). The specific IgG antibodies of uninfected people increased with the increase of inoculum times( H=287.00 and 98.48, both P<0.001). The specific IgG antibodies of people who were not infected with SARS-CoV-2 in the groups of whose interval from the last inoculation of SARS-CoV-2 vaccine to blood collection was less than three months, three to six months and more than six months were 171.86(156.04, 196.57), 71.71(17.08, 110.38) and 132.14(57.59, 172.25), respectively, and the difference was statistically significant ( H=19.93, P<0.001). Among them, the absolute difference between the less than three months group and the three to six months group was statistically significant ( Z=3.67, P<0.001), and the absolute difference between the less than three months group and the more than six months group was statistically significant ( Z=3.47, P<0.001). The specific IgG antibodies level in the less than three months group was the highest. Conclusions:There is a certain correlation between the number of SARS-CoV-2 vaccine doses and the specific IgG antibodies level in uninfected people. The specific IgG antibodies could maintain a high level for three months after immunization.

Objective To investigate the effect and mechanism of cinobufotalin in inhibiting hepatocellular carcinoma(HCC)metastasis by regulating epithelial-mesenchymal transition(EMT).Methods A total of 36 male BALB/c nude mice,aged 6 weeks,were given injection of MHCC97H cells via the caudal vein to establish a model of HCC lung metastasis,and then the mice were randomly divided into high-and low-dose cinobufotalin groups and control group.Since the day of modeling,the mice in the high-and low-dose cinobufotalin groups were given intraperitoneal injection of cinobufotalin at a dose of 120 μL/kg and 60 μL/kg,respectively,and those in the control group were given intraperitoneal injection of normal saline,twice a week.After 8 weeks,HE staining was performed for lung tissue to measure the lung metastasis rate of HCC.MHCC97H cells were treated with high-dose(2.5 μL/mL)or low-dose(5 μL/mL)cinobufotalin for 24 hours,and wound healing assay,RT-PCR,and Western blot were used to measure cell migration ability and the expression of EMT-related molecules.MHCC97H cells were induced in a simulated hypoxic environment with CoCl2 incubation,with high-and low-dose cinobufotalin added for intervention,and wound healing assay and Western blot were used to investigate the effect of cinobufotalin on cell migration ability and EMT induced by hypoxia.Transcriptome analysis was used to investigate the effect mechanism of cinobufotalin on MHCC97H cells,and Western blot was used to observe the effect of cinobufotalin on the expression levels of protein kinase B(AKT)and phosphorylated AKT(P-AKT)in MHCC97H cells.A one-way analysis of variance was used for comparison of continuous data between multiple groups,and the least significant difference t-test was used for further comparison between two groups;the independent-samples t test was used for comparison of categorical data between two groups.Results Compared with the control group,the cinobufotalin group had a significant reduction in the lung metastasis rate of HCC.Compared with the control group,cinobufotalin intervention reduced the wound healing rate of MHCC97H cells,upregulated the expression of epithelial-type molecules(t=2.860,P<0.05),and downregulated the expression of EMT transcription factors(EMT-TFs)and mesenchymal molecules(t=3.545,2.022,2.852,and 2.341,all P<0.05).Hypoxia induction upregulated the wound healing rate of MHCC97H cells and the expression levels of mesenchymal molecules and EMT-TFs(P<0.05),and cinobufotalin intervention reversed EMT change and inhibited wound healing(P<0.05).The transcriptome analysis of MHCC97H cells showed significant gene differences between the cinobufotalin group and the control group,and cinobufotalin mainly affected the expression of genes associated with tumor,metabolism,immunity,and signal transduction,with the largest number of differentially expressed genes in the AKT signal transduction pathway.Further measurement showed that cinobufotalin intervention downregulated the expression levels of AKT,P-AKT,and P-AKT/AKT in MHCC97H cells(t=2.434,3.401,and 2.258,all P<0.05).Conclusion Cinobufotalin can inhibit the metastasis of HCC,especially hypoxia-induced HCC metastasis,and regulation of EMT mediated by the AKT signal transduction pathway in HCC cells might be one of its mechanisms of action.

bjective　To analyze the drug resistance screening status and drug resistance influencing factors of high-risk groups of drug-resistant pulmonary tuberculosis in Qingdao, and to understand the inclusion of rifampicin patients in treatment, so as to provide a reference for the prevention and treatment of drug-resistant pulmonary tuberculosis. Methods　The medical records of 726 cases of drug-resistant pulmonary tuberculosis among high-risk populations registered in Qingdao from 2018 to 2022 were obtained from the National Health Insurance Information System of the China Center for Disease Control and Prevention. The drug resistance to five anti-tuberculosis drugs, namely isoniazid (INH), rifampicin (RFP), ethambutol (EMB), levofloxacin (Lfx), and amikacin (Am), in the high-risk populations of drug-resistant pulmonary tuberculosis was analyzed. Univariate and multivariate logistic regression were used toidentify factors influencing rifampicin resistance, and the detection and inclusion of treatment for rifampicin-resistant patients were evaluated. Results　Of the 726 subjects, 278 were drug-resistant, with a total drug resistance rate of 38.29%. The drug resistance for the five anti-tuberculosis drugs in descending order was: INH 25.90%(188/726), RFP 22.87%(166/726), Lfx 14.19%(103/726), EMB 11.29%(82/726), Am 2.48%(18/726). Analysis of the drug resistance spectrum showed that among those resistant to one drug, RFP was most common, accounting for 13.67% (38/278); among those resistant to two drugs, INH+RFP was predominant, accounting for 15.83% (44/278); among those resistant to three drugs, INH+RFP+Lfx was most frequent, at 7.19% (22/278); and among those resistant to four drugs, INH+RFP+EMB+Lfx was highest, at 6.12% (17/278). Multivariate logistic regression analysis of rifampicin resistance showed that compared with patients under 25 years of age, the risk of developing rifampicin resistance was lower in the groups aged 45 to under 65 and those aged 65 and above (OR=0.356, 95%CI: 0.181-0.700; OR=0.352, 95%CI: 0.170-0.729). Compared with migrant patients in other provinces, local patients from within the same county or district had a lower risk of developing rifampicin resistance (OR=0.599, 95%CI:0.383-0.962). Compared with patients who were smear-positive at the end of the second month of initial treatment, the risk of developing rifampicin resistance was higher in patients with relapse/return, failure of retreatment/chronic, and other categories of patients (OR=9.380, 95%CI:3.717-23.671;OR=25.749, 95%CI:8.037-82.490; OR=36.651, 95%CI:8.438-159.201). Conclusions　The situation of drug-resistant pulmonary tuberculosis in Qingdao cannot be ignored. Individuals under 25 years old, migrants from other provinces, and patients with relapse/return, failure of retreatment/chronic, and other categories are significant risk factors for developing rifampicin resistance in the high-risk groups of drug-resistant pulmonary tuberculosis.

【Objective】 To objectively evaluate the quality control level of blood testing process in blood banks through quantitative monitoring and trend analysis, and to promote the homogenization level and standardized management of blood testing laboratories in blood banks. 【Methods】 A quality monitoring indicator system covering the whole process of blood collection and supply, including blood donation service, blood component preparation, blood testing, blood supply and quality control was established. The questionnaire Quality Monitoring Indicators for Blood Collection and Supply Process with clear definition of indicators and calculation formulas was distributed to 17 blood banks in Shandong province. Quality monitoring indicators of each blood bank from January to December 2022 were collected, and 31 indicators in terms of blood testing were analyzed using SPSS25.0 software. 【Results】 The proportion of unqualified serological tests in 17 blood bank laboratories was 55.84% for ALT, 13.63% for HBsAg, 5.08% for anti HCV, 5.62% for anti HIV, 18.18% for anti TP, and 1.65% for other factors (mainly sample quality). The detection unqualified rate and median were (1.23±0.57)% and 1.11%, respectively. The ALT unqualified rate and median were (0.74±0.53)% and 0.60%, respectively. The detection unqualified rate was positively correlated with ALT unqualified rate (r=0.974, P<0.05). The unqualified rate of HBsAg, anti HCV, anti HIV and anti TP was (0.15±0.09)%, (0.05±0.04)%, (0.06±0.03)% and (0.20±0.05)% respectively. The average unqualified rate, average hemolysis rate, average insufficient volume rate and the abnormal hematocrit rate of samples in 17 blood bank laboratories was 0.21‰, 0.08‰, 0.01‰ and 0.02‰ respectively. There were differences in the retest concordance rates of four HBsAg, anti HCV and anti HIV reagents, and three anti TP reagents among 17 blood bank laboratories (P<0.05). The usage rate of ELISA reagents was (114.56±3.30)%, the outage rate of ELISA was (10.23±7.05) ‰, and the out of range rate of ELISA was (0.90±1.17) ‰. There was no correlation between the out of range rate, outrage rate and usage rate (all P>0.05), while the outrage rate was positively correlated with the usage rate (r=0.592, P<0.05). A total of 443 HBV DNA positive samples were detected in all blood banks, with an unqualified rate of 3.78/10 000; 15 HCV RNA positive samples were detected, with an unqualified rate of 0.13/10 000; 5 HIV RNA positive samples were detected, with an unqualified rate of 0.04/10 000. The unqualified rate of NAT was (0.72±0.04)‰, the single NAT reaction rate [(0.39±0.02)‰] was positively correlated with the single HBV DNA reaction rate [ (0.36±0.02) ‰] (r=0.886, P<0.05). There was a difference in the discriminated reactive rate by individual NAT among three blood bank laboratories (C, F, H) (P<0.05). The median resolution rate of 17 blood station laboratories by minipool test was 36.36%, the median rate of invalid batch of NAT was 0.67%, and the median rate of invalid result of NAT was 0.07‰. The consistency rate of ELISA dual reagent detection results was (99.63±0.24)%, and the median length of equipment failure was 14 days. The error rate of blood type testing in blood collection department was 0.14‰. 【Conclusion】 The quality monitoring indicator system for blood testing process in Shandong can monitor potential risks before, during and after the experiment, and has good applicability, feasibility, and effectiveness, and can facilitate the continuous improvement of laboratory quality control level. The application of blood testing quality monitoring indicators will promote the homogenization and standardization of blood quality management in Shandong, and lay the foundation for future comprehensive evaluations of blood banks.
