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.

This paper summarizes Professor DING Ying's clinical experience in the treatment of systemic lupus erythematosus （SLE） through differentiation of three states， yin fire， latent fire， and fire toxin. It is proposed that fire pathogenic factors constitute a key pathological element running throughout the entire disease course of SLE. The evolution of its pathogenesis centers on these three states， spleen-kidney deficiency with the initial emergence of yin fire as the onset of disease， damage to yin by medicinal toxicity with internal blazing of latent fire as the driver of disease progression， and the interlocking of blood stasis and heat with intense scorching by fire toxin as the critical factor leading to severe and life-threatening conditions. Corresponding to these three stages， targeted prescriptions are formulated， Jiuwei Yishen Formulation （九味益肾方） to tonify the spleen and kidney， raise yang， and disperse fire； Ziyin Xiehuo Decoction （滋阴泄火汤） to nourish yin and fluids while clearing latent fire； and Santeng Changluo Jiedu Decoction （三藤畅络解毒汤） to dispel blood stasis， unblock the collaterals， detoxify， and restrain fire. This staged and integrated therapeutic strategy aims to address both root and branch and to achieve overall regulation， providing valuable guidance for the clinical differentiation and treatment of SLE.

Objective To analyze the epidemiologic burden of colorectal cancer in Xishan District, Kunming City, Yunnan Province from 2018 to 2020. Methods Indicators of epidemiologic burden were calculated, including incidence rate, mortality rate, age-specific incidence/mortality rates, potential years of life lost (PYLL), and disability-adjusted life years (DALY) based on the National Disease Control and Prevention Center’s "Cancer Information Registration and Reporting System" and "Cause of Death Registration System". Results From 2018 to 2020, the ASR (China) for the incidence of colorectal cancer in Xishan District, Kunming City increased from 25.27/10⁵ to 26.29/10⁵, while the ASR (China) for mortality decreased from 17.11/10⁵ to 16.03/10⁵. The PYLL in 2018–2020 were 1399.63, 1376.78, and 1571.56 person-years, respectively, whereas the DALY in 2018–2020 were 1927.74, 1875.05, and 1945.17 person-years, respectively. The morbidity, mortality, PYLL, and DALY were generally higher in males than in females over 45 years of age. Conclusion Given the parallel trends of persistent incidence risk and steadily declining mortality for colorectal cancer in Xishan District, Kunming City, a three-tier prevention and control system centered on "lifestyle intervention–regular screening–positive case tracking" should be established, with a focus on covering high-risk populations, particularly males over 45 years of age.

BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

Objective:To study the feasibility and safety of left semiprone position in 3D laparoscopic liver resection for tumor in segment Ⅶ.Methods:Clinical data of 60 patients with liver tumors treated at Jinhua Central Hospita from January 2018 to September 2022 were retrospectively collected, including 40 males and 20 females, aged (51.5±4.5) years. Perioperative data on operative time, intraoperative blood loss, postoperative time of ambulation, postoperative time to flatulate, duration of hospital stay, pathological type, complications (bile leakage, pleural effusion, etc.) were analyzed. Postoperative follow-ups were conducted through telephone reviews, outpatient visits.Results:Of 57 patients (95.0%) successfully underwent the surgery, while three cases (5.0%) were converted to open surgery due to excessive intraoperative bleeding. The operative time was (210.5±20.5) min. The intraoperative blood loss was (220.5±50.5) ml. The postoperative time of ambulation was (1.5±0.5) d, and the postoperative time to flatulate was (2.0±0.8) d. The postoperative hospital stay was (7.2±1.5) d. Bile leakage occurred in four cases (6.7%) after surgery, which was managed by conservative treatment, and pleural effusion occurred in eight cases (13.3%), which recovered after puncture and drainage. Postoperative pathology included 40 cases (66.7%) of hepatocellular carcinoma, three cases (5.0%) of intrahepatic cholangiocarcinoma, five cases (8.3%) of liver metastases, seven cases (11.7%) of hepatic hemangioma, two case (3.3%) of angiomyolipoma, and three case (5.0%) of focal hepatic nodular hyperplasia. No tumor recurrence was observed during follow-up (median 26 months; range 18-40 months).Conclusion:The application of left semiprone position in 3D laparoscopic liver resection for tumor in segment Ⅶ is safe and feasible.

Objective To investigate the relationship between serum glial fibrillary acidic protein(GFAP)level and transcranial Doppler(TCD)parameters in carotid stenosis patients after carotid stent implantation.Methods A total of 123 patients with carotid stenosis who received carotid stent implantation in our hospital from September 2021 to February 2024 were recruited,and di-vided into a normal group(39 cases)and a damaged group(84 cases)according to their cerebro-vascular reserve.The GFAP level and TCD parameters were collected before and after treatment.ROC curve analysis was employed to analyze the value of GFAP level in evaluating cerebrovascu-lar reserve in the patients.Results Significantly larger proportion of diabetes and higher level of total cholesterol were observed in the damaged group than the normal group(P＜0.05).Mean flow velocity(MFV),pulse index(PI),peak systolic velocity(PSV),and levels of GFAP,neuron-specific enolase(NSE)and S-100β were all obviously decreased in both groups after surgery than the levels before(P＜0.05).When compared with the normal group,the damaged group had nota-bly higher serum GFAP level before operation,and lower PI and PSV values and higher GFAP,NSE and S-100β levels after operation(P＜0.05,P＜0.01).Both pre-and post-operative serum GFAP levels were negatively correlated with postoperative MFV,PI and PSV(P＜0.01).The concomitant diabetes,pre-and post-operative serum GFAP levels,and postoperative PSV value and NSE and S-100β levels were independent influencing factors for cerebrovascular reserve in ca-rotid stenosis patients after carotid stent implantation(P＜0.05,P＜0.01).The post-operative se-rum GFAP level showed significantly better value than the pre-operative level in assessing cere-brovascular reserve,with an AUC value of 0.860(95％CI:0.786-0.916)and 0.777(95％CI:0.693-0.847),respectively.Conclusion Serum GFAP level is related to TCD parameters in ca-rotid stenosis patients after carotid stent implantation.Combined GFAP level and TCD parameters together can be used to evaluate the cerebrovascular reserve for the patients.
