ObjectiveTo investigate the effect and mechanism of long intergenic non-coding RNA02086 （LINC02086） overexpression mediated macrophage polarization on the proliferation， migration and invasion of gastric cancer cells. MethodsThe expression levels of LINC02086 in the human gastric epithelial cell line GES-1 and human gastric cancer cell lines HCG-27， NCI-N87， and AGS were determined by qRT-PCR. Human acute monocytic leukemia cells （THP-1） were induced to differentiate into M0 macrophages using phorbol 12-myristate 13-acetate （PMA）. HGC-27 cells were infected with either LINC02086 overexpression lentivirus （OE-LINC02086） or its negative control lentivirus （Vector）， and the culture supernatants were collected as conditioned medium （CM1）. M0 macrophages were co-cultured with the infected HGC-27 cells， and the resulting supernatants were designated as conditioned medium 2 （CM2）. M0 macrophages were treated with CM1 alone or in combination with Wnt/β-catenin pathway inhibitor IWR-1， forming the Vector+CM1， OE-LINC02086+CM1， and OE-LINC02086+CM1+IWR-1 groups， respectively. Flow cytometry was used to detect mannose receptor C-type 1 （CD206） expression， and qRT-PCR was employed to measure mRNA levels of interleukin-10 （IL⁃10）， transforming growth factor-β （TGF⁃β）， vascular endothelial growth factor （VEGF）， and chemokine ligand 22 （CCL22）. Western blot was performed to evaluate protein expression of CD206， VEGF， and key components of the Wnt/β-catenin pathway—Wnt family member 3a （Wnt3a）， glycogen synthase kinase-3β （GSK-3β）， and β-catenin. HGC-27 cells were treated with CM2 alone or combined with IWR-1， establishing the Vector+CM2， OE-LINC02086+CM2， and OE-LINC02086+CM2+IWR-1 groups. CCK-8 assay was used to evaluate cell proliferation， and Transwell assays were conducted to assess migration and invasion capabilities. ResultsCompared with GES-1 cells， the expression levels of LINC02086 were upregulated in HCG-27， NCI-N87， and AGS cells （P < 0.05）， with the smallest increase observed in HCG-27 cells. Compared with Vector+CM1 group， the level of CD206 and the expression levels of IL⁃10， TGF⁃β， VEGF and CCL22 mRNA in macrophages stimulated by OE-LINC02086+CM1 increased （P<0.05）. Meanwhile， the expression levels of Wnt3a and β-catenin proteins in cells increased （P<0.05）， and the expression level of GSK-3β protein decreased （P<0.05）. However， co-treatment with IWR-1 markedly reversed the promoting effects of LINC02086 overexpression on the expression of M2 polarization markers， including CD206， IL⁃10， and TGF⁃β mRNA， in macrophages （P<0.05）， as well as its activation of the Wnt/β-catenin signaling pathway （P<0.05）. Compared with Vector+CM2 group， HGC-27 cells infected with OE-LINC02086+CM2 had increased proliferation activity and increased number of migration and invasion cells （P<0.05）. However， the combined intervention of IWR-1 significantly reversed the promotion of LINC02086 overexpression on the proliferation， migration and invasion of HGC-27 cells （P<0.05）. ConclusionLINC02086 overexpression promotes the proliferation， migration and invasion of gastric cancer cells by activating Wnt/β-catenin pathway to mediate M2 polarization of macrophages.

Objective:To analyze the clinical efficacy of vascular resection and reconstruction during radical resection in patients with hilar cholangiocarcinoma.Methods:A retrospective analysis was conducted on the clinical data of 151 patients with hilar cholangiocarcinoma who underwent radical resection in the Department of Hepatobiliary and Pancreatic Surgery at the First Affiliated Hospital of Anhui Medical University from April 2018 to April 2025. Among them, there were 91 males and 60 females, with an age of (65.4±10.5) years. According to whether radical resection of hilar cholangiocarcinoma was combined with vascular resection, the patients were divided into the vascular resection group ( n=19) and the control group ( n=132). Postoperative complications such as bleeding, biliary fistula, and thrombosis were recorded, along with intraoperative blood loss, R 0 resection rate, perioperative mortality, and recurrence rate at six months postoperatively. Results:The preoperative bilirubin reduction and intraoperative blood loss in the vascular resection group were 6 (31.6) and 200 (200, 200) ml, respectively, while those in the control group were 45 (34.1) and 200 (100, 200) ml, respectively. There were no statistically significant differences between the two groups (all P>0.05). The combined liver resection, Billroth operation type Ⅰ-Ⅱ, and operation time in the vascular resection group were 18 (94.7), 1 (5.3), and 420 (377.5, 512.5) min, respectively, while those in the control group were 79 (59.8), 38 (28.8), and 322.5 (260, 410) min, respectively. There were statistically significant differences between the two groups (all P<0.05). The R 0 resection, perioperative mortality rate, postoperative bleeding, postoperative biliary fistula, postoperative thrombosis, postoperative pathology (adenocarcinoma), and recurrence rate at 6 months after surgery in the vascular resection group were 16 (84.2), 2 (10.5), 2 (10.5), 3 (15.8), 1 (5.3), 18 (94.7), and 1 (5.9), respectively, while those in the control group were 103 (78.0), 5 (3.8), 5 (3.8), 25 (18.9), 2 (1.5), 121 (91.7), and 6 (4.7), respectively. There were no statistically significant differences between the two groups (all P>0.05). The postoperative hospital stay, alanine aminotransferase on the 1st and 3rd day after surgery, and postoperative liver failure in the vascular resection group were 18 (13.5, 21.5) days, 619 (305.4, 1 634.0) U/L, and 1 (5.3), respectively, while those in the control group were 14 (11, 18), 254.5 (139.3, 468.3) U/L, and 3 (2.3), respectively. There were statistically significant differences between the two groups (all P<0.05). Conclusion:Vascular resection and reconstruction during radical resection of hilar cholangiocarcinoma in patients has certain safety and efficacy.

Objective To investigate the high-risk factors associated with acute postoperative hypertension (APH) following laparoscopic sleeve gastrectomy(LSG) in obese patients and to establish a predictive model. Methods A retrospective analysis was conducted on clinical data and laboratory parameters of obese patients who underwent LSG at Department of Metabolic Surgery in our hospital from August 2021 to December 2023. Logistic-LASSO regression analysis was used to identify independent risk factors for APH. A nomogram predictive model was developed based on these factors. The predictive performance and clinical utility of the model were assessed using the receiver operating characteristic (ROC) curve, Bootstrap resampling, calibration curve, Hosmer-Lemeshow (H-L) test, decision curve analysis (DCA), and clinical impact curve (CIC). Results The incidence of APH was 55.90%. Body mass index (BMI), platelet count, globulin, uric acid, sodium, fibrinogen, fasting blood glucose, and preoperative diastolic pressure had potential predictive value. Among them, BMI (OR=1.066, 95% CI: 1.003-1.137, P=0.046), platelet count (OR=0.994, 95% CI: 0.998-0.999, P=0.027), fibrinogen (OR=1.943, 95% CI: 1.128-3.479, P=0.02), and preoperative diastolic blood pressure (OR=0.953, 95% CI: 0.918-0.985, P = 0.006) were identified as independent high-risk factors. The area under the curve (AUC) of the nomogram was 0.783 (95% CI: 0.711-0.855), with a sensitivity of 0.817 and a specificity of 0.689. The AUC based on Bootstrap resampling was 0.776 (95% CI: 0.702-0.849). The H-L test yielded P>0.05, and the calibration curve showed good model fit. Both DCA and CIC demonstrated favorable screening efficiency. Conclusions BMI, platelet count, fibrinogen, and preoperative diastolic blood pressure are independent high-risk factors for APH following LSG. The developed nomogram model exhibits good predictive performance and clinical applicability, providing a valuable tool for early screening and prevention of APH in LSG patients.

Segmental dystonia caused by levodopa and deep brain stimulation (DBS) in Parkinson′s disease (PD) has been described rarely and may be underrecognized in clinical practice. A case of peak-dose dyskinesia with segmental dystonia, including blepharospasm, jaw dystonia, torticollis, and dystonia in the left upper limb, after bilateral subthalamic nucleus DBS, is reported. The literatures on PD-related dystonia, including dystonia manifestations before and after treatment with medication and DBS, are reviewed to enhance clinicians′ recognition of movement disorders occurring during the treatment of PD and to improve patient outcomes.

Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.
