OBJECTIVE To provide references for the accurate identification and management of immune-related cutaneous adverse events （irCAEs） caused by durvalumab， and ensuring safe clinical drug use. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with gallbladder cancer who developed irCAEs caused by durvalumab. The clinical pharmacists systematically reviewed the patient’s past medical history and medication history， and assisted physicians in assessing the association between adverse drug reactions and administered drugs. Meanwhile， the clinical pharmacists conducted a graded assessment of the adverse reaction， proposed recommendations such as discontinuing durvalumab and adjusting the administration regimen of glucocorticoids， assisted physicians in restarting immunotherapy， and carried out medication education and other pharmaceutical care. RESULTS The occurrence of irCAEs in this patient was “highly likely” related to durvalumab and was classified as severe. The physicians adopted the clinical pharmacist’s opinion， and after symptomatic treatment， the patient’s skin symptoms improved， and discharged with medication. After the completion of glucocorticoid therapy for the patient， the physician restarted immunotherapy with tislelizumab， and no related adverse reactions occurred again in the patient. CONCLUSIONS Durvalumab can cause irCAEs such as severe skin maculopapular rash. In clinical practice， it is crucial to promptly identify and discontinue suspicious drugs， immediately implement effective symptomatic treatment measures， and actively resume immunotherapy to ensure the continuity and safety of the patient’s treatment.

Diabetic retinopathy （DR） is a microvascular complication of diabetes and one of its most common complications. Prolonged hyperglycemia induces oxidative stress， inflammatory responses， apoptosis， and pathological angiogenesis， ultimately disrupting the blood-retinal barrier（BRB） and leading to visual impairment or even blindness. Recent studies show that the nuclear factor erythroid 2-related factor 2 （Nrf2） signaling pathway plays an important role in the development of DR's pathological changes. Meanwhile， Chinese herbal monomers have been shown to modulate the Nrf2 signaling pathway， thereby intervening in the development of DR. In terms of inhibiting oxidative stress， saponin compounds such as platycodin-D and ginsenoside Rb1 downregulate the expression of malondialdehyde （MDA）， thereby ameliorating retinal oxidative stress. Flavonoids such as total flavonoids from Pueraria lobata flower and puerarin upregulate the expression of superoxide dismutase （SOD） and glutathione peroxidase （GPx）， effectively clearing lipid peroxides. Regarding the suppression of inflammation， phenolic compounds like resveratrol and chlorogenic acid inhibit the nuclear factor kappa B （NF-κB） pathway， reducing the release of tumor necrosis factor-alpha （TNF-α） and mitigating inflammatory responses. In the context of inhibiting apoptosis， polysaccharides such as Polygonatum sibiricum polysaccharide and Angelica sinensis polysaccharide downregulate the expression of the pro-apoptotic protein Bcl-2-associated X protein （Bax） and suppress the activity of the executioner Caspase-3， thereby reducing the apoptosis rate. As for the inhibition of neovascularization， compounds including bilobalide and physcion significantly decrease the protein expression of vascular endothelial growth factor （VEGF）， leading to a reduction in retinal pathological angiogenesis. Furthermore， Chinese herbal compound prescriptions such as Tongluo Zhujing pills， Yiqi Huoxue Yangyin decoction， Qiming granules， and Danlou tablets can also intervene in the onset and progression of DR through the mechanisms described above. In summary， both Chinese herbal monomers and Chinese herbal compound prescriptions can modulate the Nrf2 signaling pathway to inhibit oxidative stress， alleviate inflammation， and participate in maintaining BRB integrity， suppressing retinal neovascularization， and preventing neurodegeneration， thereby delaying the progression of DR. Therefore， this paper reviews and summarizes recent studies at home and abroad on how traditional Chinese medicine （TCM） works to treat DR， and the relationship between the Nrf2 pathway and DR. It aims to provide research ideas for preventing and treating DR.

Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

Based on the Global Burden of Disease (GBD) 2019, this study characterized the burden of dietary iron deficiency across 154 countries participating in the Belt and Road Initiative (BRI). A joinpoint regression model was employed to assess temporal trends in disease burden. Pearson correlation analysis and locally weighted regression were utilized to investigate the relationship between burden and the socio-demographic index (SDI). Slope indices and concentration indices were calculated to evaluate health inequalities, while frontier analysis explored disease burden benchmarks. Key metrics included prevalence and disability-adjusted life years (DALYs). Results revealed downward trends in age-standardized prevalence rates and age-standardized DALYs rates of dietary iron deficiency among children under 10 years old in 117 and 125 BRI countries, respectively, from 1990 to 2019. A significant negative correlation was observed between disease burden and SDI in 2019 ( R=-0.80, P<0.001). The slope indices decreased from -936 (95% CI:-1 006, -806) in 1990 to -1 128 (95% CI:-1 256, -999) in 2019, while the concentration indices declined from -0.24 (95% CI:-0.28, -0.20) to -0.35 (95% CI:-0.39, -0.30) during the same period. Frontier analysis further identified substantial gaps between observed outcomes and optimal performance thresholds in several countries.

Objective:To evaluate the association between pre-pregnancy urolithiasis and pre-eclampsia and to further explore the mediating effect of hyperuricemia in early pregnancy on the relationship between urolithiasis and pre-eclampsia.Methods:Pregnant women attending prenatal care in early pregnancy at 7 Maternal and Child Health Hospitals in Hunan Province from August 2014 to December 2019 were recruited to construct a cohort of early pregnancy. The paper questionnaire collected demographic data on pregnant women, pre-pregnancy disease history, and living habits, etc. Besides, the early pregnancy laboratory examination and pregnancy outcome for this pregnancy were derived from the hospital's electronic medical record system. Logistic regression models were used to analyze the association between pre-pregnancy urolithiasis and pre-eclampsia, and causal mediation analysis was used to investigate the mediating role and magnitude of hyperuricemia in early pregnancy in the association pathway between pre-pregnancy urolithiasis and pre-eclampsia. Results:A total of 33 579 naturally conceived singleton pregnant women were included in the analysis, of which 3 230 cases (9.6%) had hyperuricemia in early pregnancy, and 666 cases (2.0%) had pre-eclampsia. The multivariate logistic regression analysis indicated that pre-pregnancy urolithiasis increased the risk of pre-eclampsia ( OR=2.65, 95% CI: 1.56-4.51). Mediation analysis showed that after controlling for confounders, hyperuricemia in early pregnancy could mediate the association between pre-pregnancy urolithiasis and pre-eclampsia, with a mediation effect proportion of 46% ( P<0.05). Conclusions:Pre-pregnancy urolithiasis is an independent risk factor for pre-eclampsia, and early pregnancy hyperuricemia has a certain mediating effect between urolithiasis and pre-eclampsia.

Objective:To conduct a bibliometric analysis of research on auricular acupoint therapy (AAT) published between 2014 and 2024 in the China National Knowledge Infrastructure (CNKI) , in order to identify research hotspots and explore future research trends.Methods:CiteSpace, VOSviewer, and CNKI's bibliometric visualization platform were used to analyze publications from multiple perspectives, including annual publication trends, institutional distribution, author collaboration networks, keyword co-occurrence, and journal sources.Results:From 2014 to 2024, research on auricular acupoint therapy underwent a transition from rapid growth to steady development. The research focus shifted from traditional Chinese medicine theories to integration with modern neuroscience and technology. Domestic research was primarily concentrated in universities and institutes of traditional Chinese medicine, with collaboration mainly occurring at the regional level. Randomized controlled trials (RCTs) became the predominant study design, although issues related to methodological rigor persist. Keyword analysis showed a shift in research hotspots from traditional conditions like headache and insomnia to contemporary health concerns such as depression, anxiety, and hyperlipidemia.Conclusions:Auricular acupoint therapy is increasingly incorporating modern scientific and technological approaches. Research methodologies are becoming more standardized, and areas of application are continuously expanding. Future studies should focus on enhancing interdisciplinary collaboration, improving research design quality, and deepening international cooperation to promote the broader adoption and development of AAT within the global healthcare system.

Objective To explore the clinical characteristics and influencing factors for prognosis of patients with bloodstream infection(BSI)caused by Stenotrophomonas maltophilia(S.maltophilia).Methods Clinical data of patients with S.maltophilia BSI in Liuzhou People's Hospital from January 2019 to December 2023 were retro-spectively analyzed.Patients were divided into good prognosis group and poor prognosis group according to their prognosis.Risk factors for poor prognosis were analyzed by univariate analysis and binary logistic regression analy-sis.Results From 2019 to 2023,a total of 36 patients were diagnosed with S.maltophilia BSI,with an average age of(51.8±22.6)years.The most common clinical symptom was fever(91.7％),followed by respiratory symp-toms(25.0％).33 patients(91.7％)had underlying diseases,31 patients(86.1％)had healthcare-associated in-fection,and 23 patients(63.9％)underwent invasive procedures before onset.Among the 36 patients with S.mal-tophilia BSI,12(33.3％)had a poor prognosis.Univariate analysis showed that underlying blood diseases,length of hospital stay ≥30 days,agranulocytosis,and elevation of C-reactive protein(CRP)were related to poor progno-sis of patients with S.maltophilia BSI(all P＜0.05).Binary logistic regression analysis results showed that underlying blood diseases,length of hospital stay ≥30 days,and agranulocytosis were independent risk factors for poor prognosis in patients(all P＜0.05).Conclusion Patients with S.maltophilia BSI are critically ill with high mortality.Underlying blood diseases,length of hospital stay ≥30 days,and agranulocytosis are independent risk factors for poor prognosis in patients.

[Objective] To investigate the seroprevalence characteristics of hepatitis E virus (HEV) among blood donors with hepatitis B virus (HBV) infection, so as to provide data support for the monitoring, prevention and treatment of HEV. [Methods] From January to December 2022, 219 samples positive for hepatitis B surface antigen (HBsAg), 142 occult hepatitis B virus infection (OBI) samples (HBV group) and 873 samples tested negative (control group) were collected. 361 samples were further tested with viral load assay and serological testing for five serological markers (HBsAg, HBsAb, HBeAg, HBeAb and HBcAb), and the DNA load was measured using real time fluorescence quantitative PCR. Commercially available enzyme-linked immunosorbent assays (ELISA) were used for the detection of anti-HEV IgG, anti-HEV IgM and HEV antigen (Ag). The Chi-square test or Fisher's exact test was used to assess the differences in the reactivity rates of anti-HEV IgG and anti-HEV IgM among different blood donor populations and different variables. Multivariable logistic regression was used to examine potential risk factors associated with anti-HEV IgG seroprevalence. [Results] In the HBV group, HBsAg positive donors exhibited low expression of antigen. The HBV DNA load of OBI infected donors ranged from 1 to 131.43 IU/mL (median 11.24 IU/mL). The prevalence of anti-HEV IgG and IgM antibody in the HBV group were 34.63% and 1.11%, respectively. Among them, the prevalence of anti-HEV IgG and anti-HEV IgM in the HBV group was 34.63% and 0, respectively (P<0.05), while in the OBI donors, they were 41.55% and 2.82%, respectively. In the normal donors, the reactivity rates for anti-HEV IgG and anti-HEV IgM were 18.67% and 1.49%, respectively. Statistical analysis showed that there was a difference in the reactivity rate of anti-HEV IgG between the HBV-infected donors and the normal donors (34.63% vs 18.67%, P<0.05), but no difference in the reactivity rate of anti-HEV IgM (1.11% vs 1.49%, P>0.05). No HEV Ag was detected in either group of blood donors. Multivariate logistic regression analysis indicated that age was an independent risk factor for anti-HEV IgG reactivity in both groups of blood donors. [Conclusion] The reactivity rate of anti-HEV IgG among HBV-infected blood donors was significantly higher than that in the normal donors in Wuhan, with age being an independent risk factor. Therefore, for HBV-infected donors, it is essential to strengthen and prioritize the prevention and treatment of HEV to reduce the spread of HEV.

AIM:To evaluate the efficacy of intravitreal ranibizumab injection(IVR)combined with subthreshold micropulse(STMP)in the treatment of diabetic macular edema(DME).METHODS: Retrospective study. A total of 98 DME patients(98 eyes)admitted to our hospital from March 2022 to March 2023 were enrolled and divided into two groups based on treatment methods: the control group(49 eyes)received STMP yellow laser therapy alone, while the study group(49 eyes)underwent combined IVR and STMP yellow laser therapy. Comparisons were made between the two groups regarding best corrected visual acuity(BCVA), retinal neovascularization(RNV)leakage area, parafoveal macular thickness(PMT), foveal macular thickness(FMT), central retinal thickness(CRT), and foveal avascular zone(FAZ)area, quality of life was assessed using the Chinese-version low vision quality of life questionnaire(CLVQOL), and complication rates were recorded. Additionally, serum levels of nitric oxide synthase(NOS)and vascular endothelial growth factor(VEGF)were measured before and after treatment in both groups.RESULTS: At 3 mo after treatment, both groups showed improved BCVA compared to baseline, with reduced RNV leakage area, PMT, FMT, CRT, FAZ, and serum levels of VEGF, while serum NOS levels and all CLVQOL domain scores were higher than pre-treatment(all P<0.05). Furthermore, the study group demonstrated superior outcomes in all these parameters compared to the control group(all P<0.05), and no ocular or systemic complications occurred in any patient.CONCLUSION: IVR combined with STMP yellow laser for DME improves visual acuity, reduces RNV leakage area, PMT, FMT, CRT, and FAZ, modulates serum NOS and VEGF levels, enhances quality of life, and demonstrates good safety.
