[Objective] To analyze the influencing factors of repeat blood donor lapsing using a zero-inflated poisson regression model (ZIP). [Methods] The blood donation behavior of 12 498 whole blood donors from 2020 was tracked until December 31, 2023. The factors influencing the frequency of blood donations in a given year was analyzed using ZIP, and donors with 0 blood donation in that year were considered to have lapsed. The changes in relevant influencing factors associated with each blood donation were measured and modeled for analysis. [Results] The zero-inflated part of ZIP showed that the risk of lapsing of male blood donors was 2.24 times that of female blood donors (OR 95% CI:1.864-2.696, P<0.001); the risk of lapsing of the 35-44 age group and over 45 age group was respectively 40% (OR 95% CI:0.455-0.790, P<0.001) and 61%(OR 95% CI:0.268-0.578, P<0.001) lower than that of the under 25 age group; the risk of lapsing for those who have donated blood twice and ≥3 times was respectively 50% (OR 95% CI:0.405-0.609, P<0.001) and 81% (OR 95% CI:0.154-0.225, P<0.001) lower than that of first-time donors; the risk of lapsing of those with junior high or high school education was 1.2 times that of those with a college degree or higher (OR 95% CI:1.033-1.384, P<0.05); the risk of lapsing for the divorced group was 2.02 times that of the married group (OR 95% CI:1.445-2.820, P<0.001); the risk of lapsing for those with an income (Yuan) of 10 000 to 50 000, 50 000 to 100 000 and more than 100 000 was respectively 0.67 (OR 95% CI:0.552-0.818, P<0.001), 0.72 (OR 95% CI:0.591-0.884, P=0.002) and 0.67 (OR 95% CI:0.535-0.834, P<0.001) times that of those with an income (Yuan) of less than 10 000. The results of the Poisson part are consistent with the results of the zero-inflated part in terms of age and education level. [Conclusion] Blood donor lapsing is overall related to factors such as gender, age, donation frequency, education, marital status and family income. It's essential to care for those blood donors prone to lapse to retain more regular blood donors.

OBJECTIVE To observe the clinical efficacy of Erdong Xiaoke Formula in the treatment of type 2 diabetes dry eyes with yin deficiency and heat excess syndrome and its effect on serum interleukin 17(IL-17)and interleukin 1β(IL-1β),and to ex-plore the therapeutic mechanism of Erdong Xiaoke Formula.METHODS 110 cases of type 2 diabetes patients with dry eyes of yin deficiency and heat excess syndrome from Jiangsu Province Hospital of Chinese Medicine were enrolled and randomly divided into a treatment group and a control group,55 cases each.5 cases dropped out of the treatment group and 4 cases dropped out of the control group.The control group was given a basic hypoglycemic regimen combined with topical sodium hyaluronate eye drops.The treatment group was given Erdong Xiaoke Formula in addition to the treatment in the control group.The treatment course for both groups was 4 weeks.Changes in TCM syndrome scores of the two groups of patients were observed before and after treatment,and the clinical effica-cy of TCM was evaluated.Blood glucose and pancreatic islet function-related indicators[fasting blood glucose(FBG),fasting insulin(FINS),fasting C-peptide(FCP),postprandial 2 h blood glucose(PBG),insulin secretion function index(HOMA-β),insulin re-sistance index(HOMA)-IR)],ocular surface indicators[tear break up time(BUT),corneal sodium fluorescein staining(FL),Schirmer Ⅰ test(SⅠT)],and inflammation-related indicators(IL-17,IL-1β)were detected.The occurrence of adverse reactions in the two groups of patients was observed during the treatment period.RESULTS After treatment,the total scores of TCM syn-dromes in both groups were significantly reduced(P＜0.01),the treatment group was better than the control group(P＜0.01),and the total effective rate of TCM syndromes in the treatment group was higher than that of the control group(P＜0.01);SⅠT and BUT of pa-tients in both groups increased significantly(P＜0.01),and the treatment group was better than the control group(P＜0.05,P＜0.01);the FL of patients in both groups significantly reduced(P＜0.01),and there was no significant difference between the groups;the ser-um IL-17 and IL-1β of the patients in the treatment group decreased significantly(P＜0.01),which was significantly better than that of the control group(P＜0.05).There were no significant changes in blood glucose and pancreatic islet function-related indicators in the two groups before and after treatment(P＞0.05).During the treatment,no obvious adverse reactions were observed in the two groups.CONCLUSION Erdong Xiaoke Formula can improve SⅠT,BUT,FL and eye symptoms in patients with diabetic dry eye,effectively treat diabetic dry eye,and reduce ocular surface inflammation.Its mechanism may be related to reducing serum inflammato-ry factors IL-17 and IL-1β.

Objective The aim of this study was to investigate the prospective association between physical activity (PA),independently or in conjunction with other contributing factors,and osteoporosis (OP) outcomes. Methods The Physical Activity in Osteoporosis Outcomes (PAOPO) study was a community-based cohort investigation. A structured questionnaire was used to gather the participants' sociodemographic characteristics. Bone mineral density (BMD) measurements were performed to assess OP outcomes,and the relationship between BMD and OP was evaluated within this cohort. Results From 2013 to 2014,8,471 participants aged 18 years and older were recruited from Tangshan,China's Jidong community. Based on their PA level,participants were categorized as inactive,moderately active,or very active. Men showed higher physical exercise levels than women across the activity groups. BMD was significantly higher in the very active group than in the moderately active and inactive groups. Individuals aged>50 years are at a higher risk of developing OP and osteopenia. Conclusion The PAOPO study offers promising insights into the relationship between PA and OP outcomes,encouraging the implementation of PA in preventing and managing OP.

Objective To analyze medication patterns and the targets and pathways of core drug combinations in treatment of palpitation.Methods The prescriptions of Li Yaping for treatment of palpitation from March 2023 to March 2024 were collected,and frequency counts of drugs'nature and flavour,channel tropism,and efficacy were performed.Apriori algorithm,association rules,and clustering analysis were carried out using SPSS Modeler 18.0 and SPSS 26.0.The core drugs and disease targets were searched,and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis were performed on the targets of their therapeutic action for palpitation.Results A total of 220 prescriptions were collected,involving 192 flavors of traditional Chinese medicines,with a cumulative medication frequency of 3978 times,and 18 flavors of high-frequency medicines.The medicines were mainly tonics,sedative,and promoting blood circulation for removing blood stasis.The distribution of medicinal properties were mainly warm,cold and flat.The medicinal flavors were mainly sweet,bitter and pungent,and channel tropism were mostly heart,liver and spleen channel.Association rule analysis showed that Radix Angelicae Sinensis,Radix et Rhizoma Salviae Miltiorrhizae,Radix et Rhizoma Glycyrrhizae,Radix Ophiopogonis,and Radix Astragali were the core drugs.Cluster analysis showed that there was 3 cluster combinations.In the network pharmacology part,there were 181 targets intersected by drug combinations and diseases.KEGG analysis showed that the core drugs for palpitation mainly involved signaling pathways such as phosphoinositide 3-kinase/protein kinase B,hypoxia-inducible factor-1,mitogen-activated protein kinase,interleukin-17,etc.GO analysis obtained 1000 GO pathways,of which 760 were biological processes,93 were cellular components,and 147 were molecular functions.Conclusion In the treatment of palpitation,Li Yaping advocates benefiting qi and promoting yang,removing blood stasis and eliminating turbidity,and tranquilizing the mind,emphasizing the"two hearts in the same adjustment",and treating the heart and liver at the same time,taking into account the spleen and stomach,and the combination of core medicines can intervene in the course of palpitation through multi-components,multi-targets,and multi-pathways,which is of great significance for the treatment of palpitation in the clinical setting.

Objective To investigate the labial alveolar bone thickness of maxillary incisors and mesiodistal space in the maxillary adjacent central and lateral incisors based on cone beam computed tomography(CBCT)image data,and provide reference for aesthetic implantation in cases of consecutive missing maxillary incisors.Methods CBCT image data of 619 patients were selected in this study.The labial alveolar bone thickness of maxillary incisors as well as the mesiodistal space in the maxillary adjacent central and lateral inci-sors were measured at three millimeters apical to the cementoenamel junctio,followed by statistical analysis.Results The labial alveo-lar bone thickness at the maxillary central incisor and lateral incisor locations was(1.03±0.32)mm and(0.96±0.36)mm,respectively,with central incisors having greater thickness than lateral incisors.The mesiodistal space in the maxillary adjacent central and lateral incisors was(15.94±1.18)mm,with males(16.31±1.13)mm exhibiting slightly greater space than females(15.59±1.12)mm,showing no left-right positional differences.Among these,5.01%failed to satisfy a space of 14 mm.Conclusion The majority of maxillary incisors fail to meet the ideal thickness requirements of labial alveolar bone for implantation,necessitating bone augmentation surgery.For the maxillary adjacent central and lateral incisors,approximately 5.01%of the mesiodistal spaces fail to meet the essential horizontal distance for the placement of two implants.In such situations after tooth loss,it is recommended to place only one implant in the region of the central incisor and aprosthetic restoration consisting of an implant crown on this implant connected with a cantilever at the position of the lateral incisor for long-term aesthetic results.

OBJECTIVE To evaluate the cost-effectiveness of bevacizumab combined with erlotinib in the first-line treatment of advanced EGFR mutant non-squamous non-small cell lung cancer （NSCLC） from the perspective of China’s health system. METHODS A dynamic Markov model was established based on BEVERLY study data， with a cycle of 3 weeks， a research deadline until 99% of patients die， and an annual discount rate of 5%. The model outputs were total cost， quality-adjusted life year （QALY）， and incremental cost-effectiveness ratio （ICER）. Taking 3 times China’s per capita gross domestic product （GDP） in 2023 as the willingness-to-pay （WTP） threshold， the cost-utility analysis was used to evaluate the cost-effectiveness of bevacizumab combined with erlotinib （observation group） versus erlotinib alone （control group） in the first-line treatment of advanced EGFR mutant non-squamous NSCLC， and the single factor sensitivity analysis and probability sensitivity analysis were used to verify the robustness of the basic analysis results. RESULTS The results of the basic analysis showed that compared with the erlotinib therapy plan， ICER of bevacizumab combined with erlotinib was 1 452 243.01 yuan/QALY， which was more than 3 times China’s per capita GDP in 2023 （268 074 yuan/QALY） as the WTP threshold， indicating that bevacizumab combined with erlotinib was not cost-effective. The results of single factor sensitivity analysis showed that the cost of bevacizumab， the utility value of progression-free survival and progressed disease status had a great influence on the results. The results of probability sensitivity analysis showed that when the WTP threshold was 1 740 000 yuan/QALY， the probability of cost-effective of bevacizumab combined with erlotinib plan was 50%. CONCLUSIONS Compared with erlotinib alone， bevacizumab combined with erlotinib is not cost-effective in the first-line treatment of advanced EGFR mutant non-squamous NSCLC， when using 3 times China’s per capita GDP in 2023 as the WTP threshold.

Objective To retrieve, evaluate, and summarize evidence on preventive management of high output and dehydration in ileostomy patients from both domestic and international sources. Methods Based on the "6S" evidence model, a top-down approach was employed to retrieve evidence on prevention and management of high output and dehydration in ileostomy patients. Databases searched included BMJ best practice, UpToDate, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN), Registered Nurses' Association of Ontario (RNAO), Wound Ostomy and Continence Nurses Society (WOCNS), World Council of Enterostomal Therapists (WCET), Medlive Clinical Guidelines website, Joanna Briggs Institute (JBI), Cochrane Library, Embase, PubMed, Web of Science, CNKI, Wanfang Data, China Biology Medicine (CBM), and VIP Database. The search period was from January 2019 to April 2024. Results A total of 13 articles were included after retrieval and screening, comprising 2 guidelines, 2 expert consensuses, 4 systematic reviews, 4 evidence summaries, and 1 clinical decision aid. After translation, summarization, and organization of the included articles, 19 pieces of evidence across 11 categories were formulated, focusing on four items: definition and risk factors of high output in ileostomy, prevention and management strategies related to high output in ileostomy, prevention and management strategies related to dehydration in high-output ileostomy, and follow-up strategies for prevention of high output and dehydration after ileostomy surgery. Conclusion The evidence summarized based on the "6S" evidence model for prevention and management of high output and dehydration in ileostomy patients can provide a reference for clinical practice among healthcare professionals and medical decision-makers, thereby enhancing nursing quality and reducing patient rehospitalization rates.

This study aims to investigate the protective effect of resveratrol against liver injury in hindlimb unloading rats. Thirty 2-month-old male SD rats were randomly divided into normal group (Control), hindlimb unloading model group (Model), and hindlimb unloading+resveratrol administration group (Model+Res). The Model + Res group was injected intraperitoneally with 30 mg/kg of resveratrol, and the Control and Model groups were injected intraperitoneally with an equal volume of 0.9% NaCl. Liver tissues were collected after 28 days and analyzed for oxidative stress, inflammatory factors, energy metabolism indices, Na ⁺-K ⁺-ATPase and Ca ²⁺-Mg ²⁺-ATPase activity, and morphological changes were observed by hematoxylin-eosin staining. The protein expression levels of Bax, Bcl-2, p-PI3K, PI3K, p-AKT, and AKT were detected by Western blotting. Compared with the Control group, hepatocytes in the Model group showed swelling, abnormal morphology, nuclear consolidation, and cell membrane disruption. Oxidative stress, inflammatory factor levels, hepatic glycogen accumulation, and energy metabolism were increased in the liver tissues of the Model group, while resveratrol treatment significantly reversed these changes. The results of Western blotting showed that resveratrol significantly reduced the expression of Bax and increased the expression levels of Bcl-2, and the proteins of p-PI3K/PI3K and p-AKT/AKT expression levels. It is suggested that 28 days of hindlimb unloading treatment could lead to liver tissue injury in rats, which is manifested as oxidative stress, inflammatory response, energy metabolism disorder and increased apoptosis level, and resveratrol has a certain mitigating effect on this.
