Objective: To preliminarily develop a multidimensional blood donor role scale based on role theory and systematically compare the psychosocial characteristic differences between award-winning donors and first-time donors in Guangzhou, and to provide an empirical reference for formulating differentiated donor retention strategies. Methods: A cross-sectional survey design was adopted. A random sample of award-winning donors and concurrently sampled first-time donors yielding 1 361 valid responses collected (721 from the award group, 640 from the first-time group). Exploratory factor analysis was used to assess the scale structure. Data were post-stratified and weighted according to the gender and age distributions of the general donor population. Independent samples t-tests, multivariate analysis of covariance (MANCOVA), and generalized linear models were employed to compare dimensional scores between the two groups. A paired t-test was conducted to analyze the annual donation frequency of award-winning donors before and after receiving the award. Results: Exploratory factor analysis yielded a 5-factor structure, including Role Identity and Expectations, Role Adaptation and Maintenance, Role Environment and Experience, Role Relationships and Conflict, and Role Incentives and Rewards, with a cumulative variance contribution rate of 56.43%. The scale demonstrated good internal consistency reliability (Cronbach's α=0.906). Known-group validity test showed that award-winning donors scored significantly higher than first-time donors on Role Identity and Expectations (t=4.366, P<0.001, d=0.240), Role Adaptation and Maintenance (t=5.436, P<0.001, d=0.500), and Role Relationships and Conflict (t=4.844, P<0.001, d=0.220). These differences remained significant after controlling for selected demographic variables (MANCOVA, Wilks' λ=0.943, P<0.001). Generalized linear models suggested that donation frequency was an independent predictor for these dimensions. Additionally, the annual donation frequency of award-winning donors was slightly higher after receiving the award than before (t=2.007, P=0.045). Conclusion: The preliminary blood donor role scale demonstrates acceptable reliability and validity and can effectively distinguish groups with different donation behavior characteristics. The study reveals that award-winning donors exhibit more positive psychological characteristics across multiple role identity dimensions and maintain their donation behavior after receiving an award. External incentives and internal role identity may jointly contribute to behavioral persistence. The findings provide a preliminary reference for further exploring the formation pathways of donor role identity and developing differentiated donor retention strategies.

A total of 500 female medical workers were randomly selected from Xiyuan Hospital from April to December 2022 to complete the questionnaires. The relationship between lifestyle and constitutions of female medical workers was analyzed.Results:A total of 457 cases completed the questionnaires. Among the 9 constitutions, 102 people (22.32%) had a peaceful constitution, while 355 people (77.68%) had a biased constitution; the top three biased constitutions were qi stagnation constitution 90 people (19.69%), yang deficiency constitution 83 people (18.16%), and phlegm-dampness constitution 56 people (12.25%). The factors that influenced physical constitutions according to the severity of lifestyle were: sleep, diet, mood, exercise, labor, environment, children, and education.Conclusions:Female medical workers have a high proportion of biased constitution, and the main types of biased constitution are qi stagnation constitution, yang deficiency constitution, and phlegm-dampness constitution. According to the existing biased constitution, targeted adjustments and interventions are carried out, and it is of great significance to protect and care for the health of female medical workers from the concept of preventive treatment of diseases with TCM.

OBJECTIVE To explore the effects of narrative pharmacy management on medication compliance， negative emotions， and quality of life in patients with cardiovascular disease complicated with negative emotions. METHODS A total of 49 patients with drug use problems and negative emotions attending the cardiovascular pharmacy clinic of Wuhan First Hospital from February to August 2023 were selected as the study objects， narrative pharmacy model was applied for patient management during their visits； pharmaceutical care and emotional management were performed after 2 weeks of treatment and a follow-up visit was conducted to evaluate and record the management effect one month later. RESULTS Adopting a narrative pharmacy management model， 49 patients were involved in 114 drug related consultation questions. Compared with the visit， after one month of management， the number of medication types taken by patients significantly decreased [4.00 （2.00， 6.00） vs. 3.00 （1.50， 5.00）， P＜0.05]， the incidence of adverse reactions significantly decreased （32.65% vs. 2.04%， P＜0.001）， the rate of blood pressure and lipid compliance significantly increased （30.61% vs. 95.92%， P＜0.001）， and the score of the patient’s medication compliance significantly improved （[ 3.94±2.44） vs. （6.78±2.07）， P＜0.01]. The depression score significantly decreased [3.00 （2.00， 4.50） vs. 2.00 （0.00， 3.00）， P＜0.001]， the anxiety score significantly reduced [3.00 （2.00， 4.50） vs. 1.00 （0.00， 2.00）， P＜0.001]， quality of life score was significantly improved [22.00 （19.00， 22.00） vs. 23.00 （23.00， 24.50）， P＜0.01]. In the satisfaction survey， there was a slight increase in the overall satisfaction proportion （91.84% vs. 97.96%， P＞0.05）. CONCLUSIONS The application of narrative pharmacy in cardiovascular pharmacy clinic can improve patient compliance， reduce adverse drug reactions， enhance the effectiveness of drug treatment， avoid drug interactions， effectively improve the anxiety and depression， and ultimately improve the quality of life.

Objective To construct and validate a Nomogram prediction model for overall survival (OS) in middle-aged and elderly patients with stage Ⅱ to Ⅲ gastric cancer. Methods The clinical, pathological, and follow-up data of middle-aged and elderly patients with stage Ⅱ to Ⅲ gastric cancer in the Affiliated Hospital of Yangzhou University, Northern Jiangsu People's Hospital, and Yangzhou City Hospital of Traditional Chinese Medicine from March 1, 2012 to December 1, 2022 were retrospectively analyzed. Based on univariate and multivariate Cox regression analyses, the independent risk factors for OS in middle-aged and elderly patients with stage Ⅱ to Ⅲ gastric cancer were identified, and a Nomogram prediction model was further constructed and validated. The diagnostic performance of the model was evaluated by the receiver operating characteristic (ROC) curve and calibration curve, and the clinical effect of the model was assessed by decision curve analysis (DCA). Results A total of 382 patients were included. A total of 282 cases were as training sets and 100 cases were as validation sets. Univariate and multivariate Cox regression analyses indicated that family history of gastric cancer, vascular invasion, nerve invasion, T stage, and N stage were independent risk factors for OS in middle-aged and elderly patients with stage Ⅱ to Ⅲ gastric cancer (P < 0.05). A prognostic Nomogram was constructed based on these variables, and the concordance index of the model in the training and validation sets was 0.667 (95% CI, 0.601 to 0.726) and 0.708 (95%CI, 0.622 to 0.766) respectively. The ROC curve indicated that the model had good predictive accuracy. The calibration curve showed that the predicted value of the model was in good agreement with the actual value. DCA demonstrated that the model had good clinical application and potential values. Conclusion The Nomogram model for 1-, 3- and 5-year OS in middle-aged and elderly patients with stage Ⅱ to Ⅲ gastric cancer constructed based on real-world big data in this study has an ideal predictive effect, which can help clinicians effectively assess patients' prognosis.

Objective:To investigate the effect of autologous cartilage and artificial material implants on the occurrence of postoperative complications during rhinoplasty.Methods:This study included 447 patients who underwent cosmetic rhinoplasty at Hanmei Cosmetic Hospital in Dongguan. The age of enrolled patients was 18-52 years, and the mean age was 26.8±6.9 years. They were divided into an autologous cartilage group (334 patients in total) and an artificial material group (113 patients in total) according to the implant material used; the differences in postoperative complications were compared between the two groups and the influencing factors related to the occurrence of complications were analyzed.Results:The follow-up time of all patients was 3-24 months, and the mean time was 19.4 months. 51 (11.4%) of the 447 patients developed postoperative complications during the follow-up period, and the rate of functional failure in the artificial material group (16.8%) was significantly higher than that in the autologous cartilage group (9.6%) (χ 2=4.17, P=0.037). In the autologous cartilage group, the most frequent complications were irregular nasal contour, a total of 10 cases (3.0%), and infection, 8 cases (2.4%); while the most frequent complications in the artificial material group were infection, 6 cases (5.3%) and prosthesis exposure, 3 cases (2.7%). At 2-year follow-up, 32 cases of the postoperative complication rate occurred (16.8%) in the autologous cartilage group, which was significantly higher than that of 19 cases (9.6%) in the artificial material group, and the difference between the two groups was statistically significant (log-rank χ 2=4.37, P=0.039). The results of the multifactorial COX risk factor analysis showed that history of smoking ( HR=1.78, 1.21-2.29, P=0.004), previous history of rhinoplasty ( HR=2.89, 2.08-3.97, P<0.001) and use of artificial materials ( HR=1.34, 1.17-2.08, P=0.013) and external incision (protective factor, HR= 0.92, 0.78-0.98, P=0.037) were independent risk factors for the development of functional complications. Conclusions:Neither the use of autografts nor artificial implants in rhinoplasty prevents the occurrence of complications, and the types of complications occurring in both differ, with artificial grafts having a higher rate of postoperative complications.

Objective:To summarize the perinatal management and prognosis of congenital chylous ascites (CCA).Methods:Clinical data of 20 infants diagnosed with CCA and treated in Guangdong Women and Children Hospital from June 2015 to November 2020 were retrospectively analyzed and described.Results:There were ten patients with isolated CCA and ten with non-isolated CCA. In isolated CCA cases, seven were cured after conservative treatment and three after postoperative conservative treatment following an ineffective surgery. Non-isolated CCA cases were complicated by intrauterine cytomegalovirus infection ( n=1), malrotation of intestine ( n=4) or bilateral chylothorax ( n=5). In addition to conservative treatment for CCA, non-isolated CCA patients also received antiviral therapy, Ladd's procedure or intrauterine/extrauterine closed thoracic drainage. Of eight patients who were firstly diagnosed with ascites before 30 gestational weeks, including four isolated and four non-isolated cases, only one underwent surgical intervention. During hospitalization, serious infections occurred in three infants with isolated CCA and two with non-isolated CCA, and were all controlled by anti-infection treatment. During a follow-up to median age of 29 months (15-82 months), none of the patients had any abnormalities except for the one with intrauterine cytomegalovirus infection who was deaf at the age of two. Conclusions:Conservative management is effective and the prognosis is generally good for most cases with isolated CCA. Treatment and prognosis of non-isolated CCA depend on its comorbidities. Gestational age at diagnosis may not be a prognostic predictor.

Objective:To investigate the distribution and drug resistance of pathogens causing blood stream infection in patients with pancreatic neoplasms.Methods:Clinical data of patients with pancreatic neoplasms complicated with bloodstream infection with confirmed pathological evidence admitted in the First Affiliated Hospital of Naval Medical University from January 2016 to June 2019 were collected. Bacteria were isolated from blood culture, and microbial sensitivity tests were analyzed by minimum inhibitory concentration and Kirby-Bauer methods. The distribution and drug resistance of pathogens causing blood stream infection in patients with pancreatic neoplasms were analyzed.Results:There were 116 cases (8.5%) with bloodstream infection in 1 372 patients with pancreatic neoplasms. A total of 156 bacterial strains were isolated from blood culture, of which 127 strains (81.4%) were gram negative aerobic bacteria, mainly including Escherichia coli (42 strains), Klebsiella pneumoniae (34 strains), Pseudomonas aeruginosa (12 strains), and 25 strains (16.0%) were gram positive aerobic bacteria, mainly including Enterococcus faecium (11 strains), Enterococcus faecalis (3 strains), Streptococcus angina (3 strains). 4 strains (2.6%) were anaerobic bacteria. The results of antibiotic susceptibility showed that the resistance rate of Escherichia coli to ampicillin was 90.5%, and to cefoperazone-sulbactam was 2.4%. The resistance rate of Klebsiella pneumoniae to piperacillin was 20.6%, and to cefoperazone-sulbactam was 5.9%. The resistance rate of Pseudomonas aeruginosa to imipenem was 41.7%, and no resistant strain was found to cefoperazone-sulbactam. The resistance rate of Enterococcus and Streptococcus pharyngitis to erythromycin were 85.7% and 33.3%, and no strains were resistant to vancomycin.Conclusions:The rate of blood stream infection in patients with pancreatic neoplasms was relatively high. In clinical practice, the distribution of pathogenic bacteria should be understood, the drug resistance should be monitored and antibiotics should be reasonably used, in order to maximally prevent and interfere with the occurrence of blood stream infection.
