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.

Background: Adrenocortical hormones, particularly 11-oxygenated androgens, are pivotal in female reproductive health and fertility. Standardized detection kits and population-specific reference intervals are lacking in China, hindering related clinical applications. Methods: A HPLC-tandem mass spectrometry (HPLC-MS/MS) pipeline was developed, rigorously validated, and applied to simultaneously quantify corticosterone, cortisone, cortisol, 18-OH cortisol, androstenedione (A4), 11β-hydroxyandrostenedione (11-OH A4), dehydroepiandrosterone, and dehydroepiandrosterone sulfate in serum samples from 455 reproductive-aged women (18–45 yrs) in Guangxi, China. Age-dependent concentration trends were analyzed, and reference intervals stratified by age (2.5th to 97.5th percentiles) were established. Correlations with body-composition metrics, ethnicity, and the menstrual cycle were investigated. Results: The HPLC-MS/MS method demonstrated high precision (intra- and inter-assay CVs < 15%), accuracy, and sensitivity. All eight hormones exhibited significant age-related declines (P < 0.001 for seven hormones; P = 0.001 for 11-OH A4). Notably, 11-OH A4 levels were significantly lower in the 35–45-yr (3.05 nmol/L) and 25–34-yr (3.09 nmol/L) age groups than in the 18–24-yr (3.57 nmol/L) age group, whereas no significant difference was observed between the 35–45-yr and 25–34-yr age groups. Weak negative correlations were observed between the body mass index and corticosterone and cortisone levels, whereas ethnicity and the menstrual cycle showed no significant associations with hormone levels. Conclusions We developed an HPLC-MS/MS-based method for simultaneously quantifying eight adrenocortical hormones, including 11-OH A4, and defined age-specific reference intervals for reproductive-aged Chinese women. These findings advance the clinical utility of adrenocortical hormones in diagnosing and managing reproductive disorders.

Objective To explore the relationship between serum levels of soluble triggering receptor expressed on myeloid cells-1(sTREM-1),procalcitonin(PCT)combined with endotoxin(ET)and prognosis of patients with severe pneumonia.Methods 200 cases of severe pneumonia and 100 cases of common pneumonia admitted to Jinhua People's Hospital from January 2022 to January 2023 were selected as study group and control group respectively.Patients in study group were divided into death group and survival group according to the prognosis of 28 days.Serum sTREM-1,PCT and ET levels were detected in all patients,and the differences among all groups were compared;The relationship between serum indexes and acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)on the first day of admission was analyzed;Receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficacy of serum sTREM-1,PCT and ET levels on the first day after admission to the hospital.Results Serum sTREM-1,PCT and ET levels in study group were significantly higher than those in control group on the 1st day after admission(P＜0.05).Serum sTREM-1,PCT,ET levels and APACHE Ⅱ score in death group were significantly increased on the 4th and 7th day after admission compared with the 1st day(P＜0.05),while the above indexes in survival group were significantly decreased on the 4th and 7th day after admission compared with the 1st day(P＜0.05).Serum sTREM-1,PCT,ET levels and APACHE Ⅱ scores in severe pneumonia death group were significantly higher than those in survival group on the 1st day,4th day and 7th day after admission(P＜0.05).Serum sTREM-1,PCT,ET levels were positively correlated with APACHE Ⅱ score(P＜0.05),and serum indexes were positively correlated in severe pneumonia patients on the 1st day after admission(P＜0.05).When serum sTREM-1＞56.90ng/L on the 1st day after admission,the sensitivity and specificity of patients with severe pneumonia was 89.13％and 75.32％respectively;When PCT＞12.97μg/L,the sensitivity and specificity was 76.09％and 85.06％;When ET＞13.62pg/ml,the sensitivity was 73.91％and the specificity was 66.88％;The sensitivity and specificity was 89.13％and 96.75％respectively detected by the three indexes combined.Conclusion Serum sTREM-1,PCT,ET levels are highly expressed in severe pneumonia,which is closely related to the prognosis of patients,and the combined detection of the three indexes is of great value in predicting the death of patients with severe pneumonia.

Objective To investigate the correlation between serum microRNA-210(miR-210),tumor necrosis factor-stimulated gene 6(TSG-6),and complement C1q tumor necrosis factor-related protein 3(CTRP3)and their association with myocardial fibrosis and prognosis in patients with dilated cardiomyopathy(DCM).Methods A total of 117 patients with DCM admitted to Taizhou People's Hospital between March and August 2024 were enrolled in the DCM group.Based on cardiac magnetic resonance imaging findings,these patients were further classified into a myocardial fibrosis group(n=96)and a non-fibrosis group(n=21).Additionally,according to the occurrence of acute heart failure during one-year follow-up,they were categorized into a heart failure group(n=47)and a non-heart failure group(n=70).Concurrently,58 age-and sex-matched healthy volunteers were recruited as the control group.Serum levels of miR-210,TSG-6,CTRP3,N-terminal propeptide of type Ⅲ procollagen(PⅢNP),left ventricular ejection fraction(LVEF),and N-terminal pro-B-type natriuretic peptide(NT-proBNP)were measured and compared across all groups.Results The DCM group exhibited significantly higher serum levels of miR-210,TSG-6,PⅢNP,and NT-proBNP,lower CTRP3 levels,and reduced LVEF compared to the healthy controls(P<0.05).Similarly,the fibrosis group showed elevated serum levels of miR-210,TSG-6,PⅢNP,and NT-proBNP,decreased CTRP3 levels,and impaired LVEF relative to the non-fibrosis group(P<0.05).The heart failure group also demonstrated higher serum concentrations of these biomarkers,along with lower CTRP3 and reduced LVEF,compared to the non-heart failure group(P<0.05).Serum miR-210 and TSG-6 levels were positively correlated with PⅢNP and NT-proBNP(P<0.05)and negatively correlated with LVEF(P<0.05).Multivariate analysis revealed that elevated serum miR-210(OR=2.065,95%CI:1.116～3.821)and TSG-6(OR=1.047,95%CI:1.013～1.083)were independent risk factors for heart failure in DCM patients(P<0.05),whereas higher CTRP3 levels(OR=0.911,95%CI:0.849～0.978)were associated with a protective effect(P<0.05).The sensitivity of serum miR-210,TSG-6,and CTRP3 in predicting heart failure in DCM patients was 72.34%,74.47%,and 74.47%,respectively,with specificities of 62.86%,62.86%,and 68.57%,yielding AUC values of 0.669,0.712,and 0.759,respectively.Conclusions Serum levels of miR-210 and TSG-6 are elevated,whereas CTRP3 levels are reduced in patients with DCM.These biomarkers are closely associated with myocardial fibrosis and cardiac function impairment.Moreover,miR-210,TSG-6,and CTRP3 exhibit significant predictive value for the prognosis of DCM.

Objective To investigate the clinical efficacy and aesthetic outcome of liposuction combined with mammary adenectomy through a periareolar small incision in the management of gynecomastia(GYN).Methods From January 2019 to June 2023,18 patients with GYN were admitted.All of them were treated with small incision through the areola combined with liposuction.The postoperative aesthetic effect,occurrence of complications and patient satisfaction of the patients were evaluated.Results All 18 patients in this study were follwed up for a period of 3 to 18 months.No serious complications such as wound infection or necrosis of the nipple-areola occurred.Pathological examinations were consistent with the diagnosis of GYN.Except for one patient,who exhibited slight skin folds in the surgical area at the 12-month follow-up,the other patients all achieved symmetrical and smooth chest contours with noticeable aesthetic improvement,resulting in a 100％patient satisfaction rate.Conclusion The combined approach of liposuction combined with mammary adenectomy through a periareolar small incision for the treatment of GYN is straightforward,minimally invasive,and yields satisfactory therapeutic and aesthetic outcomes.

Objective To analyze the research hotspots and frontier trends in the field of physical therapy for Parkinson's disease(PD)from 2014 to 2023.Methods Relevant literatures published from January,2014 to December,2023 were retrieved from the Web of Science Core Collection.CiteSpace 6.3.R1 was used to conduct bibliometric analysis,generating visual maps of coun-tries,institutions,keyword co-occurrence,burst terms,timelines and clustering,and they were summarized based on both visual results and literature content.Results A total of 400 articles were included.The United States had the highest publication volume,followed by China,Italy and Brazil,and the international collaboration was relatively active.Major contributing institutions included Northwestern University,Rush University,Karolinska Institutet and Universidade de S?o Paulo.Keyword co-oc-currence analysis showed that researches mainly focused on interventions such as exercise,postural control,aero-bic exercise and transcranial direct current stimulation.Burst detection analysis showed that keywords with high attention in recent years included motor symptoms,executive function,resistance training and noninvasive brain stimulation.The timeline map indicated a shift in research themes from early focus on electrical stimulation to in-tegrated interventions involving both motor and cognitive functions.Conclusion Over the past decade,researches on physical therapy for PD has shown steady growth,with increasing diver-sity in intervention strategies.There is a clear trend toward multidimensional integration and interdisciplinary col-laboration.Future studies should strengthen interventions targeting non-motor symptoms and promote the clinical application of new rehabilitation technologies.

Aim Systematic evolution of ligands by exponential enrichment(SELEX)techniquewas employed to screen and identify nucleic acid aptamers that specifically bind to mouse atherosclerotic pathological tissues,aiming to pro-vide a research foundation for the development of molecular targets and diagnostic reagents for early atherosclerosis.Methods A single-stranded DNA(ssDNA)library with a capacity of 1015～1016 was constructed,which was then subjec-ted to binding-elution(negative selection)with normal mouse vascular tissue slices.The eluted library was subsequently bound to atherosclerotic tissue slices for binding-elution(positive selection).PCR was used to amplify the positive and negative screening products,and agarose gel electrophoresis was used to verify the amplified products.The ssDNA library after multiple rounds of selection was sequenced using T-A cloning and sequencing to obtain the primary structure of the nu-cleic acid aptamers,and the secondary structure was predicted using the Mfold online software.The selected nucleic acid aptamers were labeled with a FAM fluorescent group at the 5'-end and were bound to both positive and negative selection tissue slices,with fluorescence intensity observed under a fluorescence microscope.Image Pro Plus 6.0 was used to cal-culate the relative average fluorescence intensity to evaluate the binding specificity of nucleic acid aptamers.Results After 8 rounds of selection,agarose gel electrophoresis imaging showed PCR amplification products in the positive selection lanes,while no PCR amplification products were observed in the negative selection lanes,indicating the successful acquisi-tion of a nucleic acid aptamer library that specifically binds to atherosclerotic tissues.Five nucleic acid aptamers were i-dentified by T-A cloning and sequencing,and their predicted secondary structures all had stem-loop structures.Immuno-fluorescence staining verified that five nucleic acid aptamers had different degrees of binding with As blood vessels,and the quantitative results of the relative average fluorescence intensity showed that nucleic acid aptamer No.11 had the highest relative average fluorescence intensity value,which can be used as a candidate nucleic acid aptamer for subsequent re-search.Conclusion Specific nucleic acid aptamers that bind to atherosclerotic vesselswere successfully obtained,providing a research foundation for further screening of early molecular targets of Asand developing in vivo early diagnostic reagents.

Aim To detect the changes of serum cardiotrophin-1(CT-1)and angiopoietin-like protein 3(ANGPTL3)levels in patients with coronary heart disease(CHD)complicated with heart failure(HF)after percutaneous coronary intervention(PCI),and analyze their relationship with prognosis.Methods 199 patients with CHD compli-cated with HF who underwent PCI in the Second Affiliated Hospital of Zhengzhou University from March 2022 to March 2023 were selected.The serum CT-1 and ANGPTL3 levels of patients with different New York Heart Association(NYHA)cardiac function grades were compared before surgery.The prognosis was followed up after PCI,and the pa-tients who had major adverse cardiovascular event(MACE)were included in the poor prognosis group,and the rest were included in the good prognosis group.The general data and serum CT-1 and ANGPTL3 levels were compared between the poor prognosis group and the good prognosis group.Logistic regression model was used to analyze the influencing factors of poor prognosis after surgery in patients with CHD and HF.The predictive value of serum CT-1 and ANGPTL3 alone and in combination were analyzed.Results Compared with the patients with cardiac function grade Ⅰ,the serum CT-1 and ANGPTL3 levels of the patients with cardiac function grade Ⅱ,Ⅲ and Ⅳ were increased(P＜0.05).Compared with the patients with cardiac function grade Ⅱ,the serum CT-1 and ANGPTL3 levels of the patients with cardiac function grade Ⅲ and Ⅳ were increased(P＜0.05).Compared with the patients with cardiac function grade Ⅲ,the serum CT-1 and ANGPTL3 levels of the patients with acrdiac function grade Ⅳ were increased(P＜0.05).Spearman correlation a-nalysis showed that the serum CT-1 and ANGPTL3 levels were positively correlated with NYHA cardiac function grade(r=0.518,95％CI:0.408～0.613,P＜0.001,r=0.737,95％CI:0.666～0.794,P＜0.001).The poor prognosis rate of patients was 17.93％.Compared with the good prognosis group,the serum CT-1 and ANGPTL3 levels of the poor progno-sis group were increased(P＜0.05).Logistic regression model analysis showed that smoking,diabetes,lesion vessel number ≥3,irregular medication outside the hospital,serum CT-1 and ANGPTL3 levels were the influencing factors of poor prognosis in patients with CHD complicated with HF(P＜0.05).ROC curve analysis showed that the sensitivity and area under the curve(AUC)of combined serum CT-1 and ANGPTL3 levels for predicting poor prognosis of patients with CHD complicated with HF were higher than those of either marker alone,while the specificity was basically similar to that of sin-gle-marker prediction.Conclusion Serum CT-1 and ANGPTL3 levels are abnormally elevated in patients with CHD complicated with HF after PCI,and are closely related to the cardiac function and prognosis.
