Objective: To explore the distribution characteristics and influencing factors of adverse reactions in whole blood donation in Jinan, Shandong, so as to provide evidence for the prevention and control of such adverse reactions in this region. Methods: A retrospective analysis was conducted on whole blood donors and adverse reaction cases in Jinan during 2023. To explore influencing factors of adverse reactions, univariate and multivariate logistic regression analyses were used to examine the relationships between adverse reactions and factors such as gender, age, donation organization mode, donation frequency, donation volume, time slot, and health examination results. Results: A total of 122 961 whole blood donations were recorded in Jinan in 2023. Donation-related adverse reactions occurred in 2 054 cases, with an incidence rate of 1.67%. Univariate analysis revealed significant differences in the incidence of adverse reactions across donor characteristics: the rate was higher in females (2.35%, 921/39 192) than in males (1.35%, 1 133/83 769), donors aged 18-25 years had the highest incidence (3.48%, 1 799/51 733), the incidence in group donations (3.13%, 1,737/55 534) was significantly higher than in individual donations (0.47%, 317/67 427), and insufficient blood collection was closely associated with adverse reactions (all P<0.001). Multivariate logistic regression analysis identified group donation, female gender, and a pulse rate of 81-99 beats per minute as risk factors for adverse reactions (all P<0.001), while systolic blood pressure of 116-139 mmHg and diastolic blood pressure of 76-89 mmHg were protective factors (all P<0.05). Compared to younger and lower-weight donor groups, older and higher-weight donors had a significantly lower risk of adverse reactions (all P<0.05). Donors giving 400 mL had a higher risk than those giving 200 mL (P<0.001). In addition, compared with the donation time slot of 7:00-8:59, the risk of adverse reactions was significantly higher during 9:00-16:59, with the time slot of 13:00-14:59 showing the most prominent risk (all P<0.05). However, no statistically significant difference was observed between the time slot of 17:00-20:59 and that of 7:00-8:59 (P>0.05). The primary clinical manifestation of adverse reactions was donation-related vasovagal reaction, with mental tension being the leading precipitating factor, accounting for 69.08% (1 419/2 054) of cases. Conclusion: The occurrence of adverse reactions in whole blood donation in the Jinan is influenced by multiple factors, including donor demographic characteristics, donation organization mode, physiological indicators, and time of donation. It is recommended to enhance the identification and intervention for high-risk groups, and optimize donation processes and service models to reduce the incidence of adverse reactions, thereby ensuring donor safety and blood quality.

Objective:To investigate the epidemic characteristics of human brucellosis and the awareness of brucellosis prevention and control knowledge among occupational populations in Xuzhou City, Jiangsu Province.Methods:The data of brucellosis cases reported from January to December 2023 in the China Disease Prevention and Control Information System's Infectious Disease Surveillance System where the current residence was Xuzhou City, were collected. The epidemiological distribution characteristics across the three dimensions (time, region, and population) were analyzed, and the etiological characteristics of Brucella strains collected from sentinel hospitals in Xuzhou City during the same period were analyzed. Meanwhile, in September 2023, a survey was conducted on the awareness of brucellosis prevention and control knowledge among occupational populations in 7 counties (cities, districts) with a high incidence of brucellosis in Xuzhou City. Binary logistic regression was used to analyze the influencing factors. Results:In 2023, a total of 124 human brucellosis cases were reported in Xuzhou City, with an annual incidence rate of 1.37/100 000. Brucellosis occurred in all months of the year, with a peak incidence from May to August, accounting for 46.77% (58/124). The incidence rate of brucellosis in Feng County, Pei County, Suining County, Xinyi City and Pizhou City (1.86/100 000) was higher than that in Gulou District, Yunlong District, Quanshan District, Jiawang District and Tongshan District (0.71/100 000), with a statistically significant difference (χ 2 = 19.15, P < 0.001). Among 124 cases of brucellosis, 81 cases (65.32%) were males and 43 cases (34.68%) were females. The incidence rate of brucellosis in males (1.78/100 000) was higher than that in females (0.96/100 000), with a statistically significant difference (χ 2 = 11.08, P < 0.001). The 55 - 64 age group reported a relatively higher number of cases (45 cases, 36.29%), with an incidence rate of 3.97/100 000. The main occupation was farmers (85 cases, 68.55%). In 2023, a total of 9 strains of Brucella were collected from the sentinel hospitals in Xuzhou City, all of which were Brucella melitensis, mainly classified as biotype 3 (7/9). In 2023, a total of 984 occupational population with brucellosis were surveyed in Xuzhou City, and the overall awareness rate of brucellosis prevention and control knowledge was 3.25% (32/984). By binary logistic regression analysis, the awareness rates of brucellosis prevention and control knowledge among veterinarians and those with high school or vocational school education, college education or above were relatively high [ OR (95% CI): 21.24 (1.52 - 297.74), 13.32 (3.48 - 50.96), 18.90 (3.68 - 97.13), P < 0.05]. Conclusions:In 2023, the incidence rate of human brucellosis in Xuzhou City is at a relatively high level, with men, middle-aged and elderly people, and farmers as the main population. The awareness rate of brucellosis prevention and control knowledge among occupational population is relatively low, and it is necessary to strengthen publicity, education, and behavioral intervention.

Hepatocellular carcinoma(HCC)expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming.Aldolase A(ALDOA)plays a prominent role in glycolysis;however,little is known about its role in HCC development.In the present study,we aim to explore how ALDOA is involved in HCC proliferation.HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout,which is consistent with ALDOA overexpression encouraging HCC prolifera-tion.Mechanistically,ALDOA knockout partially limits the glycolytic flux in HCC cells.Meanwhile,ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase;ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function.A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun,and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells.In HCC patients,the expression level of ALDOA was correlated with the phosphorylation level of c-Jun(Thr93)and poor prognosis.Remarkably,hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models,and the knockdown of Aldoa strikingly decreased HCC development in vivo.Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription,opening additional avenues for anti-cancer therapies.

This study investigated the therapeutic effects and mechanisms of Modified Yiyi Fuzi Baijiang Powder on ulcerative colitis(UC) in rats from the perspective of dampness. SD rats were randomly allocated into six groups(n=10): control, model, mesalazine, and Modified Yiyi Fuzi Baijiang Powder at low(3.96 g·kg~(-1)·d~(-1)), medium(7.92 g·kg~(-1)·d~(-1)), and high(15.84 g·kg~(-1)·d~(-1)) doses. UC was induced in all groups except the control by administration with 3% dextran sulfate sodium(DSS) solution for 7 days. The disease activity index(DAI) was recorded, and the colon tissue was collected for analysis. Histopathological changes were assessed by hematoxylin-eosin staining. Serum levels of D-lactic acid(D-LA) and diamine oxidase(DAO) were measured by ELISA. Immunohistochemistry and PCR were employed to evaluate the expression of aquaporins(AQP3, AQP4) and tight junction proteins [zonula occludens-1(ZO-1) and occludin] at both protein and mRNA levels. Compared with the control group, the model group showed an increased DAI scores(P<0.05), intestinal mucosal damage, elevated serum levels of DAO and D-LA(P<0.05), and decreased expression of AQP3, AQP4, ZO-1, and occludin(P<0.05). Treatment with Modified Yiyi Fuzi Baijiang Powder reduced the DAI scores(P<0.05), lowered the serum levels of D-LA and DAO(P<0.05), and upregulated the expression of AQP3, AQP4, ZO-1, and occludin at both protein and mRNA levels compared with the model group. These findings suggest that Modified Yiyi Fuzi Baijiang Powder exerts therapeutic effects on UC by reducing the intestinal mucosal permeability, promoting colonic mucosal repair, and regulating abnormal intestinal water metabolism, which may involve the upregulation of AQP3 and AQP4 expression.
