[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

Objective To investigate the acceptance and satisfaction of tuberculosis prevention and control personnel in Beijing with the patient management system, and to provide a basis for further improving the patient management model. Methods A survey was conducted on the current usage, satisfaction, willingness to use and system improvement opinions of the patient management system among medical staff involved in the supervision and medication management of pulmonary tuberculosis patients in Beijing. Results A total of 360 medical staff participated in the survey. ^“Patient management^” was the function with the largest number of users, accounting for 96.94%. The proportion of users of each module who believed that the module's design met actual work needs was over 90%. About 94.44% of respondents believed that patient management systems facilitated the transfer and sharing of information between institutions. And 90.83% of respondents thought that the patient management system was easy to operate, and 89.17% of respondents believed that patient management systems reduced workload. About 97.50% of respondents were satisfied with the overall use of the patient management system. The results of the influencing factor analysis showed that those with 3 or less modules designed to meet actual work were less satisfied than those with more than 3 modules, and the difference was statistically significant (P=0.001). Respondents put forward suggestions for improvement on the optimization of operational details such as system response speed, interface design, system login and query statistics. Conclusion Medical staff involved in the follow-up management of pulmonary tuberculosis patients are highly satisfied with their work using the patient management system. During the promotion and use, it is still necessary to continuously optimize the system functions according to work needs so that the system can truly facilitate work.

Aconitum (Ranunculaceae) has a long-standing history in traditional Chinese medicine (TCM), where it has been widely used to treat conditions such as rheumatoid arthritis (RA), myocardial infarction, and heart failure. However, the potency of Aconitum alkaloids, the primary active components of Aconitum, also confers substantial toxicity. Therefore, assessing the efficacy and toxicity of these Aconitum alkaloids is crucial for ensuring clinical effectiveness and safety. Metabolomics, a quantitative method for analyzing low-molecular-weight metabolites involved in metabolic pathways, provides a comprehensive view of the metabolic state across multiple systems in vivo. This approach has become a vital investigative tool for facilitating the evaluation of their efficacy and toxicity, identifying potential sensitive biomarkers, and offering a promising avenue for elucidating the pharmacological and toxicological mechanisms underlying TCM. This review focuses on the applications of metabolomics in pharmacological and toxicological studies of Aconitum alkaloids in recent years and highlights the significant role of metabolomics in exploring compatibility detoxification and the mechanisms of TCM processing, aiming to identify more viable methods for characterizing toxic medicinal plants.

Background and Aims:Intrahepatic cholangiocarcinoma(ICC)is a highly malignant liver tumor,with an increasing incidence worldwide,particularly in Asia.Although radical surgical resection is currently the only potentially curative treatment,the high recurrence rate and low postoperative overall survival(OS)rate of ICC remain major clinical challenges.Adjuvant therapy(AT)and neoadjuvant therapy(NAT)are important strategies to reduce postoperative recurrence and prolong OS.Several studies have shown certain efficacy of these treatments.However,the specific efficacy and safety of combined NAT and AT in ICC treatment require further validation.This study was conducted to evaluate the value of combining NAT and AT in improving the therapeutic outcomes of ICC patients through a multicenter retrospective analysis,so as to provide scientific evidence for optimizing treatment strategies.Methods:The clinicopathologic data of 576 patients with ICC who underwent radical resection and were pathologically confirmed from 13 hospitals in China between December 2011 and December 2017 were retrospectively collected.Patients were grouped based on their treatment modality:NAT+AT group,AT group,and non-NAT/AT group.The three patient groups were matched pairwise in a 1∶1 ratio using propensity score matching(PSM)to balance baseline data.The Kaplan-Meier method was used to analyze OS and disease-free survival(DFS),and subgroup analyses were conducted according to the 8th edition of the AJCC TNM staging system.Results:A total of 395 ICC patients were included in the final analysis,with 42 patients(10.6%)in the NAT+AT group,62 patients(15.7%)in the AT group,and 291 patients(73.7%)in the non-NAT/AT group.Before PSM,significant differences were observed between groups in terms of CA19-9,liver function Child-Pugh classification,intraoperative blood loss,surgical margin,differentiation grade,vascular invasion,ECOG score,and lymph node dissection ratio(all P<0.05).After PSM,there were no significant differences in baseline characteristics between the groups(all P>0.05).After matching,the median OS and DFS in the NAT+AT group were significantly better than in the AT and non-NAT/AT groups(both P<0.05),while there were no significant differences in OS and DFS between the AT and non-NAT/AT groups(both P>0.05).Subgroup analysis showed that in TNM stage I patients,DFS in the NAT+AT group was significantly better than in the non-NAT/AT group(P<0.05),but OS was not significantly different(P>0.05).In TNM stage Ⅱ and Ⅲ patients,both OS and DFS in the NAT+AT and AT groups were significantly better than in the non-NAT/AT group(both P<0.05),and DFS in the NAT+AT group was significantly better than in the AT group in TNM stage Ⅲ patients(P<0.05).Conclusion:NAT combined with AT provides better survival benefits for patients with locally advanced ICC,but its benefit for early-stage ICC patients is limited.However,the retrospective design and sample size limitations of this study may affect the stability of the results,and future large-sample,multicenter,prospective studies are needed for further validation.

Objective:To analyze the correlation and consistency of urine protein creatinine ratio (UPCR) with 24-hour urine protein quantification (24hUTP) in patients with lupus nephritis (LN).Methods:LN patients were enrolled from the STAR cohort of Peking University First Hospital, The time period is January 1, 2007 to July 31 2024. The correlation and consistency of UPCR with 24hUTP were analyzed in overall patients and various subgroups, such as,the levels of proteinuria and multiple parameters. The correlation was analyzed using Spearman′s method. The consistency was evaluated by using Kappa test, cross tabulation consistency probability, and UPCR/24hUTP ratio.Results:A total of 261 LN patients were included in this study. Overall, UPCR was positively correlated with 24hUTP ( r=0.892, P<0.001), and the consistency between then was good ( Kappa=0.603, P<0.001). Subgroup analysis based on multiple levels including different urine volume, eGFR grading, albumin, urea nitrogen, total cholesterol, low-density lipoprotein cholesterol, SLEDAI-2K, also revealed good correlation ( r=0.747~0.951; P<0.001) and consistency ( Kappa=0.393~0.771; P<0.001). Patients were divided into subgroups according to the 24hUTP (≤ 0.5 g, >0.5 g to ≤1.0 g, >1.0 g to ≤3.5 g, and>3.5 g). The best correlation and consistency were observed in ≤ 0.5g group ( r=0.728, Kappa=0.395, P<0.001), while the correlation was average or poor in other subgroups ( r=0.16~0.46). The consistency evaluated by UPCR/24hUTP ratio showed good consistency (ratios between 0.8~1.2) in 74 patients (28.4%), however, the unsatisfactory consistency in most patients, with 128 patients (68.4%) having ratios < 0.8, indicating a significantly lower UPCR than 24hUTP, and 59 patients (31.6%) having ratios > 1.2, indicating significantly higher UPCR than 24hUTP.The cross tabulation evaluation showed that the probability of consistency was distributed in a gradient, we found the worst consistency (48.9%) in >0.5 g to ≤1.0 g group, moderate consistency (64.0%) in >1.0 g to ≤3.5 g group, and the best consistency (73.3%) in >3.5 g group. Conclusion:In LN patients, the overall correlation and consistency between UPCR and 24hUTP are good, but the degree of correlation and consistency is closely related to the total amount of proteinuria. When 24hUTP ≤ 0.5 g, UPCR can be used to replace 24hUTP, but UPCR cannot be simply equated with 24hUTP at other urinary protein levels. Detecting 24hUTP to accurately reflect the total amount of proteinuria remain necessary.

Objective To explore the mechanism of Tongdu Xingshen acupuncture,the clinical efficacy,systemic inflammatory response,blood-brain barrier and intestinal flora in patients with cognitive impairment after ischemic stroke(IS)were studied.Methods Thirty patients(3 cases shedding)with cognitive impairment after IS were included as the disease group,including patients before treatment as the disease group,patients after Tongdu Xingshen acupuncture treatment as the electroacupuncture group,and 30 healthy controls(3 cases shedding)were included as the healthy group.In the electroacupuncture group,on the basis of the basic treatment,Tongdu Xingshen acupuncture was applied,which was 30 min each time,once a day for 14 days.The MMSE,MoCA and MBI scores of the three groups were observed.The fecal and serum samples from all study subjects were collected,and 16S rDNA sequencing technology and ELISA were used to detect the changes of proinflammatory factors IL-6,IL-1β,TNF-α and S100β in serum in intestinal flora and feces.Results Compared with the healthy group,the MMSE,MoCA,and MBI score of patients in the disease group decreased significantly(P<0.05),serum proinflammatory factors and S100β protein content increased significantly(P<0.05),and the Shannon index(P<0.01)and Simpson index(P<0.001)increased significantly.Compared with the disease group,the MMSE,MoCA,and MBI score of the EA group increased significantly(P<0.05),the serum levels of proinflammatory factors and S100β decreased significantly(P<0.05),Shannon index and Simpson index decreased(P>0.05).The dominant bacterial flora in the healthy group mainly included Bacteroides,Bifidobacterium,Bacteroides,Faecalibacterium,Bifidobacteriaceae,Ruminococcaceae,and Bacteroides and other beneficial bacteria(P<0.05).The dominant flora in the disease group included Proteobacteria,Enterobacteriaceae,Escherichia,Klebsiella and other opportunistic bacteria(P<0.05),while the dominant flora in the EA group was consistent with the healthy group,the relative abundance of beneficial bacteria increased significantly(P<0.05),and the relative abundance of opportunistic bacteria decreased significantly(P<0.05).Spearman correlation analysis found that beneficial bacteria were positively correlated with clinical efficacy related indicators,but with serum proinflammatory factors and the content of S100β was negatively correlated.Conclusion Tongdu Xingshen acupuncture can regulate the diversity of intestinal flora to increase the abundance of Bacteroides,Bifidobacterium,Faecalibacterium,and other beneficial bacteria,regulate the intestinal microecological balance,Thereby regulating systemic inflammation and blood-brain barrier function,which plays a role in improving cognitive function.

Objective:To explore the molecular mechanism by which interferon regulatory factor 1 (IRF1) affects hepatic ischemia-reperfusion injury (HIRI) by regulating the polarization of Kupffer cells.Methods:Twelve male healthy C57BL/6 wild-type mice weighing 20-25 g and aged 6-8 weeks were divided into a sham operation group ( n=6) and a HIRI group ( n=6); Twelve male healthy C57BL/6 IRF1 gene knockout (IRF1 -/-) mice weighing 20-25 g and aged 6-8 weeks were divided into a sham operation IRF1 -/- group ( n=6) and a HIRI IRF1 -/- group ( n=6). The levels of serum alanine transaminase (ALT) and aspartate transaminase (AST) in mice were measured, and hematoxylin-eosin (HE) staining of liver tissues was performed for Suzuki scoring to evaluate liver injury. Fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to evaluate the mRNA levels of IRF1 and tumor necrosis factor α (TNFα) in liver tissues. Flow cytometry and qRT-PCR were used to detect the proportion and functional changes of M1/M2-type Kupffer cells in liver tissues. IRF1 was overexpressed or knocked down in the mononuclear macrophage cell line ANA1, and a co-culture and hypoxia-reoxygenation system with the hepatocyte cell line AML12 was established. Flow cytometry was used to detect the apoptosis of AML12 cells. Results:At 12 hours after hepatic ischemia-reperfusion in wild-type mice, the liver tissue injury was the most severe. Compared with the sham operation group, the levels of serum ALT [(8 073±83) U/L vs. (81±19) U/L, q=13.59] and AST [(11 170±2 890) U/L vs. (412±210) U/L, q=13.77] in the HIRI group were significantly higher, and the differences were statistically significant (both P<0.001). The Suzuki score reached 5-6 points. At 12 hours after hepatic ischemia-reperfusion in IRF1 gene knockout mice, the liver tissue injury was not obvious. There were no significant differences in the levels of serum ALT [668 (514, 2 344) U/L vs. 254 (147, 285) U/L, q=2.52, P=0.348] and AST [1 936 (1 262, 2 003) U/L vs. 628 (423, 759) U/L, q=1.22, P=0.824] between the HIRI IRF1 -/- group and the sham operation IRF1 -/- group. Compared with the HIRI group, the ratio of M1/M2-type Kupffer cells in the liver of the HIRI IRF1 -/- group decreased [(0.958±0.090) vs. (2.788±0.258), q=2.06, P<0.0001], and the mRNA expression of TNFα decreased [(4.363±0.393) vs. (12.900±5.504), q=5.59, P=0.018], and the differences between the two groups were statistically significant. In the co-culture and hypoxia-reoxygenation experiment using ANA1 cells overexpressing IRF1 and AML12 cells, the proportion of AML12 hepatocytes in late apoptosis was higher than that in the control group [(14.05±4.25) vs. (3.15±1.16), t=2.85, P=0.047], and the difference was statistically significant. In contrast, when the expression of IRF1 was knocked down, the proportion of apoptotic AML12 cells decreased [(9.26±3.04) vs. (13.36±4.64), t=2.15, P=0.098], but the difference was not statistically significant. Conclusion:The IRF1 protein can regulate the polarization of Kupffer cells into M1-type macrophages, promote the inflammatory injury of the liver tissue after ischemia-reperfusion, and increase the apoptosis of hepatocytes.

OBJECTIVE To explore the serum growth hormone(GH)of the children with infectious pneumonia and analyze its association with blood biochemistry and body immunity.METHODS A total of 211 children with infec-tious pneumonia who were treated in Huaihe Hospital,Henan University from Jan.2023 to Jan.2024 were recrui-ted as the research subjects and were divided into the mild group with 156 cases and the severe group with 55 cases according to the severity of disease.The change of serum GH and the levels of blood biochemical indexes and im-munity indexes were observed and compared between the two groups.Multivariate logistic regression analysis was performed for the influencing factors,receiver operating characteristic(ROC)curves were drawn to analyze the predictive efficiencies.Linear regression analysis was performed to observe the relationship between the infectious pneumonia and the blood biochemistry and body immunity.RESULTS The GH level of the severe group was(18.34±4.33)μg/L,higher than(10.16±2.84)μg/L of the mild group(t=15.853,P＜0.001).There were sig-nificant differences in the blood biochemistry indexes,cellular and humoral immunity indexes between the severe group and the mild group(P＜0.05).The difference values of changes of C-reactive protein(CRP),CD4+and immunoglobulin(Ig)G were the most(t=16.023,87.639,111.957,all P＜0.001).ROC curve analysis showed that the area under the curve(AUC)of CD23+was the highest,with the sensitivity 100.00％,the specificity 98.88％.The result of the linear regression analysis showed that the GH was only positively correlated with the cellular immunity index CD23+(P＜0.05).CONCLUSION The GH level of the children with infectious pneumonia is reduced;the chang of GH level is closely associated with the blood biochemical indexes CRP and the body im-munity of the children.
