Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Objective To investigate the incidence and epidemiological characteristics of herpes zoster in Jinshan District, Shanghai, in 2024, and to provide a scientific basis for the development of prevention and control measures. Methods The visit information of herpes zoster cases in 2024 was collected through the outpatient diagnosis and treatment system of medical institutions in Jinshan District. Descriptive epidemiological methods were used for statistical analysis. Results In 2024, there were a total of 7 270 cases of herpes zoster in Jinshan District, including 3 398 male cases and 3 872 female cases. The incidence rate among females was higher than that among males (χ² =125.25, P< 0.001). Cases occurred in all age groups, with an average age of 59.58 ± 15.28 years. The highest proportion of cases was in the 50-year-old group (21.99%) and the 60-year-old group (25.45%). The incidence rate increased with age (χ² = 4 505.99, P< 0.001). The main departments for consultation were dermatology, pain clinics, and neurology. The main clinical diagnoses were herpes zoster without complications, postherpetic neuralgia, and incomplete herpes zoster. Among the cases, 3,102 patients had follow-up visits, and the number of follow-up visits increased with age. From 2020 to 2024, a total of 2,032 doses of herpes zoster vaccine were administered in the district, with the highest vaccination rate in the 50-year-old group (54.48%). Conclusion The majority of herpes zoster cases in Jinshan District are concentrated in the 50- and 60-year-old groups. The main complication is postherpetic neuralgia. The incidence rate and number of follow-up visits increase with age. The vaccination rate of herpes zoster vaccine in the entire district is relatively low. It is recommended to enhance monitoring and analysis, carry out health education for key populations (aged 50 years old and above), and promote vaccination and other preventive and control measures.

Pancreatic cancer has emerged as one of the most challenging malignancies worldwide,with its high resistance to chemotherapy being the primary cause of treatment failure.Therefore,enhancing the chemosensitivity of pancreatic cancer has become a major focus of current research.In this study,we in-vestigated how Bufotaline,a bufadienolide extracted from the traditional Chinese medicine toad venom,exhibits its antitumor activity.Specifically,we explored the potential of Bufotaline to enhance the chemo-sensitivity of pancreatic cancer cells to Adriamycin and elucidated its underlying molecular mechanisms.Using CCK-8 and colony formation assays,we demonstrated that Bufotaline enhances the inhibitory effect of Adriamycin on the survival of pancreatic cancer cell lines Patu-8988T,Aspc-1,and Patu-8988S.No-tably,Bufotaline treatment reduced the IC50 of Adriamycin in drug-resistant pancreatic cancer cells to lev-els comparable to those in non-resistant cells.Results from Western blot,immunofluorescence,comet as-say,and TUNEL assays revealed that Bufotaline promotes Adriamycin-induced DNA damage in pancreatic cancer cells.RNA-seq analysis of Patu-8988T cells treated with Adriamycin alone or in combination with Bufotaline showed significant changes in gene expression,and qRT-PCR analysis further confirmed that Bu-fotaline downregulates the expression of DNA damage repair proteins NBS1 and RAD50.Moreover,Western blot analysis revealed that Bufotaline reduces the levels of DNA damage response repair proteins,and Im-munofluorescence experiments indicated that Bufotaline inhibits the activation of the ATM/CHK2 signaling pathway.Finally,in a subcutaneous xenograft mouse model,the combination of Adriamycin and Bufotaline treatment significantly suppressed pancreatic cancer cell growth.In conclusion,Bufotaline enhances Adria-mycin-induced chemosensitivity in pancreatic cancer cells;the combination of Adriamycin and Bufotaline downregulates the expression of DNA damage response repair proteins NBS1 and RAD50,and inhibits the ATM/CHK2-mediated DDR signaling pathway,thereby delaying DNA damage repair.

Objective:To explore the application effect of comprehensive exercise program led by specialized nurses in patients with coronary heart disease(CHD)and type 2 diabetes mellitus(T2DM).Methods:We enrolled 386 CHD+T2DM patients admitted in Provincial Hospital Affiliated to Fuzhou University between April and December 2022.The patients were divided into control group(n=193)and intervention group(n=193)according to the order of their admission.The patients in control group received routine treatment and follow-up,while those in the in-tervention group received additional individualized exercise rehabilitation program led by specialized nurses.Both groups were intervened for 24 weeks.Levels of blood glucose[fasting blood glucose(FBG),glycosylated hemoglo-bin A1c(HbA1c)],blood lipids[low density lipoprotein cholesterol(LDL-C),total cholesterol(TC)],left ven-tricular ejection fraction(LVEF)and 6min walking distance(6MWD)were compared between two groups at dis-charge and six months after discharge.Results:Compared with patients in control group after 6-month interven-tion,those in intervention group had significant lower FBG[(5.30±0.97)mmol/L vs.(5.52±1.04)mmol/L],HbA1c[(5.60±0.65)％vs.(5.78±0.95)％],LDL-C[(1.88±0.52)mmol/L vs.(2.01±0.48)mmol/L],TC[(3.85±0.82)mmol/L vs.(4.04±0.75)mmol/L],and significant higher LVEF[(59.67±4.84)％ vs.(57.22±6.45)％]and 6MWD[(504.66±75.21)m vs.(487.75±56.16)m](P＜0.05 or＜0.01).Conclusion:Special-ized nurse-led exercise rehabilitation program could effectively control blood glucose and lipid levels,improve heart function,exercise endurance and prognosis in patients with type 2 diabetes mellitus and coronary heart disease.

Objective To observe the value of hypoperfusion intensity ratio(HIR)of CT perfusion(CTP)for predicting infarct core progression and prognosis of acute ischemic stroke(AIS).Methods Totally 271 AIS patients were retrospectively enrolled and divided into rapid progression group(group A,n=92)and slow progression group(group B,n=179)according to infarction growth rate(IGR).Clinical data,CTP parameters,treatment strategies and patients' outcome were compared between groups.Receiver operating characteristic curve was drawn,the area under the curve(AUC)was calculated to evaluate the efficacy of HIR for predicting rapid progression in infarct core of AIS.The mediating relationships among HIR,IGR and modified Rankin scale(mRS)90 days after treatment were analyzed.Results Significant differences of National Institute of Health stroke scale(NIHSS)score,Alberta stroke program early CT score(ASPECTS),also of interval time between onset and CTP,infarct core volume,hypoperfusion volume,HIR,whether intravenous thrombolysis and mRS score 90 days after treatments were found between groups(all P＜0.05).The AUC of HIR for predicting infarct core progression of AIS was 0.856,with sensitivity and specificity was 73.91％and 81.56％,respectively,when the optimal cutoff value was 0.42.IGR was a complete mediating variable between HIR and mRS score 90 days after treatment.Conclusion HIR of CTP could be used to effectively predict infarct core progression of AIS,which completely affected prognosis through mediating variable IGR.

Objective To study the diagnostic value of Sysmex UF5000 urine analyzer detection of renal tubular epithelial cells (RTEC) and pathological cast (Path. CAST) in urine to screen for hyperbilirubinemia-induced renal injury. Methods A retrospective analysis was conducted on the urine sediment analysis results of patients with hyperbilirubinemia who visited the Quanzhou First Hospital from February 2023 to January 2024. According to the occurrence of renal injury,they were divided into a non-renal injury group(n=174)and a renal injury group(n=84). Compared the RTEC levels and the positive rate of Path. CAST in urine between two groups. Receiver operating characteristic(ROC) curve analysis was used to evaluate the diagnostic performance of RTEC screening for hyperbilirubinemia-induced renal injury,and further analyzed the sensitivity,specificity,positive predictive value(PPV),and negative predictive value(NPV) of RTEC and Path.CAST single or combined screening. Results The RTEC[5.2(3.2～12.3)/μl]level in the renal injury group,and the positive rate of Path.CAST positivity rate (36.90％),which was significantly higher than that of the non-renal injury group[1.3 (0.7～2.2)/μl,3.45％],the differences were statistically significant (Z/x2=-10.215,51.620,all P<0.001). RTEC could effectively screen patients with renal injury in hyperbilirubinemia,with an AUC (95％CI) of 0.892 (0.846～0.939) and an optimal cut-off value of 3.15/μl for screening. The Youden index was 0.688. When RTEC>3.15/μl or Path.CAST positive was used,its sensitivity and NPV for screening for hyperbilirubinemia-induced renal injury were the highest,with 83.33％ and 91.57％,respectively. When Path.CAST positive was used as the screening condition,its specificity and PPV were the highest,with 96.55％ and 83.78％,respectively. Conclusion Urinary RTEC can effectively screen for renal injury caused by hyperbilirubinemia when RTEC ≤ 3.15/μl or Path.CAST is negative,the possibility of renal injury caused by hyperbilirubinemia can be ruled out.
