[摘 要] 目的：探讨复发/转移性鼻咽癌（NPC）接受含PD-1单抗免疫治疗的临床特征和预后影响因素。方法：回顾性分析2019年3月至2024年7月期间南部战区总医院确诊的95例NPC患者的临床资料和外周血生化及免疫学指标。预后分析采用Kaplan-Meier曲线，组间比较使用Log-rank检验，采用Cox比例风险模型进行单因素和多因素分析。结果：95例患者中男性81例，女性14例，中位年龄49.72岁（16~74岁），Ⅳ期91例（95.79%），所有患者均采用免疫治疗，联合或不联合化疗方案治疗，中位无进展生存期（mPFS）为10.5个月，客观缓解率（ORR）70.53%，疾病控制率（DCR）89.47%，接受含铂治疗方案患者PFS相对更长，且差异有统计学意义。紫杉醇 + 顺铂 + 氟尿嘧啶（TPF）对比吉西他滨 + 顺铂（GP）和紫杉醇 + 顺铂（TP）显示出更长的PFS，但差异无统计学意义。不同PD-1单抗治疗组间的PFS未显示出有统计学意义的差异。单因素及多因素Cox回归分析结果显示，肿瘤复发状态、初始血浆EBV感染状态、治疗周期数、基线外周血SII是复发/转移性NPC患者接受PD-1抑制剂治疗疗效预测的独立相关因素（均P < 0.05），并且非复发患者、初始血浆EBV DNA阳性、接受 ≥ 4治疗周期、基线外周血SII < 772.81的患者接受PD-1抑制剂治疗预后相对更好。结论：在接受PD-1抑制剂治疗的复发/转移性NPC患者中，非复发患者、初始血浆EBV DNA阳性、≥ 4治疗周期且外周血SII < 772.81者PFS相对更长，可早期识别免疫治疗效果不佳患者并精准干预。

With the increasing severity of bacterial antibiotic resistance， finding new ways to overcome this global challenge has become an urgent task. Chinese medicine， with abundant resources， offers potential for discovering diverse bioactive ingredients to enhance antibiotic efficacy and alleviate the crisis of bacterial antibiotic resistance. This review summarizes bacterial resistance mechanisms， prevention strategies， and the roles and mechanisms of Chinese medicine and its active ingredients in enhancing the efficacy of existing antibiotics. Two major resistance mechanisms—bacterial obstruction of antibiotic uptake and weakening of intracellular antibiotic activity—are introduced， with corresponding prevention and control strategies outlined. Based on the regulatory effects of active ingredients from Chinese medicine on bacteria， their mechanisms for enhancing antibiotic efficacy are categorized into two types， including improving the bacterial uptake of antibiotics and reducing the bacterial resistance to antibiotics. The former mainly enhances extracellular antibiotic uptake by regulating membrane permeability， biofilm formation， and metabolic pathways. The latter weakens intracellular antibiotic resistance by inhibiting efflux pumps and bacterial resistance targets. Furthermore， compound formulas of Chinese medicine， characterized by multi-component， multi-target， and multi-pathway interventions， exert similar antimicrobial effects and mechanisms with active ingredients， offering rich resources for developing antibiotic-enhancing applications. Finally， the review highlights the challenges such as insufficient structural research on active ingredients and potential druggability issues in their application for antibiotic enhancement. This will provide insights for advancing the research on Chinese active ingredients in antibiotic therapy and offers novel strategies to combat bacterial antibiotic resistance.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Rapid and ultrasensitive detection of pathogen-associated biomarkers is vital for the early diagnosis and therapy of bacterial infections. Herein, we developed a close-packed and ordered Au@AgPt array coupled with a cascade triggering strategy for surface-enhanced Raman scattering (SERS) and colorimetric identification of the Staphylococcus aureus biomarker micrococcal nuclease (MNase) in serum samples. The trimetallic Au@AgPt nanozymes can catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) molecules to SERS-enhanced oxidized TMB (oxTMB), accompanied by the color change from colorless to blue. In the presence of S. aureus, the secreted MNase preferentially cut the nucleobase AT-rich regions of DNA sequences on magnetic beads (MBs) to release alkaline phosphatase (ALP), which subsequently mediated the oxTMB reduction for inducing the colorimetric/SERS signal fade away. Using this "on-to-off" triggering strategy, the target S. aureus can be recorded in a wide linear range with a limit of detection of 38 CFU/mL in the colorimetric mode and 6 CFU/mL in the SERS mode. Meanwhile, the MNase-mediated strategy characterized by high specificity and sensitivity successfully discriminated between patients with sepsis (n = 7) and healthy participants (n = 3), as well as monitored the prognostic progression of the disease (n = 2). Overall, benefiting from highly active and dense "hot spot" substrate, MNase-mediated cascade response strategy, and colorimetric/SERS dual-signal output, this methodology will offer a promising avenue for the early diagnosis of S. aureus infection.

Objective To investigate the influencing factors of disease progression and prognosis in patients with large artery atherosclerotic(LAA)cerebral infarction and analyze the value of plasma cyclin-dependent kinase 9(CDK9)level in the diagnosis and treatment of LAA cerebral infarction.Methods Patients with acute cerebral infarction admitted to the Department of Neurology of the Affili-ated Hospital of Yangzhou University between March 1,2022,and November 20,2023,were select-ed.According to the diagnostic criteria,98 patients with acute LAA(LAA group)and 33 patients with acute small artery occlusion(SAO)cerebral infarction(SAO group)were selected.Additionally,40 healthy individuals matched for age and gender from the Health Examination Center were included as control group.Based on whether the condition of LAA cerebral infarction patients progressing,they were divided into progressive cerebral infarction(PCI)group(39 patients)and the non-pro-gressive cerebral infarction(NPCI)group(59 patients).During the 3-month follow-up period,6 patients from the 98 LAA cerebral infarction patients were lost.According to the modified Rankin Scale(mRS)score at 90 days of follow-up,patients were divided into good prognosis group(mRS score≤2,59 patients)and poor prognosis group(mRS score＞2,33 patients).Fasting lipid in-dices[total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),glucose(GLU),glycated hemoglobin(HbA1c),and homocysteine(Hey)]were collected on the second day after admission.The National Institutes of Health Stroke Scale(NIHSS)was used to assess the degree of neurological impairment in cerebral infarction patients.Enzyme-linked immunosorbent assay(ELISA)was used to measure plasma CDK9 levels in different groups;factors influencing disease progression in patients with acute LAA cerebral infarction were explored;and receiver operating characteristic curves were plotted to evalu-ate the predictive value of CDK9 in patients with acute LAA cerebral infarction.Results Compared with the control group,the LAA group had lower HDL-C level and higher CDK9 level(P＜0.05).The LAA group had a higher proportion of diabetes history,larger infarction volume,higher NIHSS score at admission,and higher CDK9 level compared with the SAO group(P＜0.05).Binary Logistic regression analysis showed that diabetes history and plasma CDK9 levels were influencing factors for LAA cerebral infarction.There were statistically significant differences in the proportion of diabetes history,HbA1c,random GLU,and CDK9 levels between the NPCI and PCI groups(P＜0.05).Diabetes history and plasma CDK9 levels were influencing factors for disease progression in patients with acute LAA cerebral infarction.The area under the ROC curve for CDK9 in predicting acute LAA cerebral infarction was 0.854 5(95％CI,0.794 1 to 0.9148).When the CDK9 level was 602.1 ng/L,the Youden index was maximum(0.604),with a corresponding sensitivity of 0.849 and specificity of 0.755.The NIHSS score,infarction volume,and plasma CDK9 level were higher in the poor prognosis group compared with the good prognosis group(P＜0.01).Correlation analysis showed a positive correlation between mRS scores and CDK9 levels(r=0.485,P＜0.01).Conclusion Plasma CDK9 levels are significantly elevated,and is an influencing factor.It is positively correlated with disease progression and poor prognosis in acute cerebral infarction and has certain predictive value for the progression of LAA cerebral infarction.

Objective:To investigate the current situation of coping styles in Crohn's disease patients and its related influencing factors.Methods:A total of 80 patients with Crohn's disease admitted to our hospital from Apri 2021 to Dec 2022 were selected to evaluate their coping styles with a simple coping style questionnaire,and relevant data were collected.The factors affecting the coping styles of Crohn's disease were analyzed by multivariable logistic regression.Results:Among the 80 patients,29 cases were negative coping,the incidence was 36.25% .There were 51 patients with positive coping(63.75% ).Educational level,simplified Crohn's disease activity index(CDAI)score,adverse psychology,social support and type D personality were associated with negative coping(P＜0.05).Gender,age,family history,working status,monthly family income,place of residence,and marital status were not associated with negative coping in patients with Crohn's disease(P＞0.05).Multivariable logistic regression analysis showed that education level of high school or below(OR=2.945,95% CI:1.139-7.614),higher CDAI score(OR=11.999,95% CI:4.387-32.815),poor psychology(OR=5.950,95% CI:2.180-16.239),low social support(OR=3.598,95% CI:1.370-9.448)and type D personality(OR=3.208,95% CI:1.118-8.904)were risk factors for negative coping in patients with Crohn's disease(P＜0.05).Conclusions:The incidence of negative coping in patients with Crohn's disease is higher,which is related to high school education or below,high CDAI score,poor psychology,low social support,and type D personality.Therefore,clinical measures can be taken to promote patients to actively cope with the disease.

Objective To investigate the value of the liver imaging reporting and data system v2018(LI-RADS v2018)and other imaging features in predicting preoperative risk and postoperative prognosis of isolated macrotrabecular-massive hepatocellular carcinoma(MTM-HCC).Methods Patients with isolated hepatocellular carcinoma(HCC)confirmed by pathology after preoperative MRI examination were selected,and all patients were randomly assigned to a training group(n=146)and a validation group(n=62)in a 7∶3 ratio.Least absolute shrinkage and selection operator(LASSO)regression and multivariate logistic regression were used to screen independent prognostic factors of MTM-HCC and construct a nomogram.Patients were stratified into high-risk and low-risk subgroups based on the nomogram scores.Kaplan-Meier survival curves and Log-rank tests were used to compare the recurrence-free survival(RFS)among different subgroups of patients.Results Multivariate logistic regression analysis revealed that intratumoral vessels[odds ratio(OR)=3.480,95％confidence interval(CI)1.110-10.912,P=0.032],arterial phase hypovascular component ≥20％(OR=4.615,95％CI 1.728-12.321,P=0.002),and corona enhancement(OR=4.814,95％CI 1.816-12.766,P=0.002)were independent predictors of MTM-HCC.The nomogram constructed based on these indicators demonstrated area under the curve(AUC)of the receiver operating characteristic(ROC)curve was 0.834 and 0.764 for predicting MTM-HCC in the training and validation groups,respectively.The RFS predicted by the nomogram was significantly different between the high-risk and low-risk subgroups and both the pathologically confirmed MTM-HCC positive and negative groups(P＜0.05).Conclusion Intratumoral vessels,arterial phase hypovascular component ≥20％,and corona enhancement are independent predictors of MTM-HCC.The constructed nomogram based on these predictors demonstrates good diagnostic efficacy for MTM-HCC and has significant prognostic value for patients'RFS.

Objective To explore the research status and future development trends of nursing case teaching at home and abroad,and to provide reference and guidance for the development of case teaching in nursing profession in China.Methods Data sources include the China National Knowledge Infrastructure(CNKI),Wanfang Data,and Web of Science databases.The CiteSpace software was used to visually analyze the research status and trends of nursing case teaching from January 2013 to Octo-ber 2023,covering nearly 11 years.Results A total of 2 889 valid articles were extracted.The important literature on nursing case teaching in China experienced a period of stable growth followed by rapid growth from 2013 to 2021.However,the number of publications and the number of publications in core journals on nursing case teaching abroad were higher than those in China.After 2021,both domestic and foreign publications on nursing case teaching showed a slow decline.The research on nursing case teaching in both domestic and foreign contexts is mainly conducted by universities,and the collaborative relationships between for-eign institutions and scholars are stronger than those within China.The research topics and hotspots in both domestic and foreign contexts are concentrated on the teaching applications for nursing students.Conclusion Nursing case teaching in China contin-ues to attract attention;however,compared to nursing case teaching abroad,the depth and breadth of research need to be further improved.Additionally,the collaboration between domestic authors and institutions is relatively limited.

Objective To observe the value of the scoring model of MRI features for predicting proliferative hepatocellular carcinoma(HCC).Methods Data of 241 patients with pathologically confirmed HCC,including 90 cases of proliferative HCC and 151 cases of non-proliferative HCC were analyzed retrospectively.Univariate and multivariate logistic regression were used to compare the clinical and MRI findings evaluated according to liver imaging reporting and data system version 2018 between groups.The independent predictive factors of proliferative HCC were screened,and scores were assigned according to the weight,then a scoring model was constructed.Receiver operating characteristic(ROC)curve was drawn,and the area under the curves(AUC)were calculated to assess the predictive efficacy of this model.The patients were divided into high and low proliferation risk subgroups based on the optimal score thresholds.The recurrence free survival(RFS)rates and early RFS rates were compared between groups and subgroups.Results MRI showed tumor corona enhancement,arterial phase annular hyper-enhancement,intratumoral vessels,much focus parenchymal low enhancement and irregular tumor margins were all independent predictive factors for proliferative HCC(OR=3.287,2.362,4.542,2.997,2.379,all P＜0.05),which were then were scored with 7,5,9,7 and 5,respectively,with a total score of 0-33.AUC of the obtained scoring model for predicting proliferative HCC was 0.818.Taken 9 points as the optimal score thresholds,97 cases were assigned into high proliferation subgroup and 144 into low proliferation risk subgroups).Significant differences of RFS rates and early RFS rates were found between groups and subgroups(all P＜0.05).Conclusion MRI features scoring model could effectively predict proliferative HCC.
