OBJECTIVE To investigate the mechanism of isochlorogenic acid A against hepatocellular carcinoma based on the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway and multi-omics technology. METHODS The invasion rate and migration rate of human hepatocellular carcinoma HepG2 cells after 48 h of intervention with 0 （control group）， 0.25 and 0.5 mg/mL isochlorogenic acid A were examined； mRNA expression of DEP domain-containing mTOR-interacting protein （DEPTOR）， the protein expressions of mTOR， PI3K and phosphatase and tensin homologue deleted on chromosome ten （PTEN）， as well as the phosphorylation level of Akt protein were determined in the cells. Metabolomics analysis was performed using liquid chromatography-tandem mass spectrometry， and differential metabolites were screened and subjected to Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis； transcriptomics monitoring was conducted by RNA sequencing， and differentially expressed genes were screened and subjected to gene ontology （GO） and KEGG pathway enrichment analyses. RESULTS Compared with the control group， intervention with 0.25 and 0.5 mg/mL isochlorogenic acid A for 48 h significantly inhibited the invasion rate and migration rate of HepG2 cells， significantly up-regulated the mRNA expression of DEPTOR and the protein expression of PTEN， and significantly down-regulated the protein expression of PI3K and the phosphorylation level of Akt protein （except for 0.25 mg/mL isochlorogenic acid A） （ P ＜0.05）. A total of 304 differential metabolites and 212 differentially expressed genes were screened by multi-omics analysis. KEGG pathway enrichment analysis suggested that isochlorogenic acid A regulated key signaling of HepG2 cell growth mainly by inhibiting the PI3K/Akt signaling pathway， synergizing with metabolic reprogramming such as mTOR signaling pathway， ferroptosis， pentose phosphate pathway and purine/pyrimidine metabo lism. CONCLUSIONS The anti-hepatocellular carcinoma effect of isochlorogenic acid A is associated with the blockade of abnormal activation of the PI3K/Akt/mTOR signaling pathway. In addition， it may also be related to the inhibition of the pentose phosphate pathway and purine/pyrimidine metabolism， as well as the induction of ferroptosis，etc.

Objective To compare the efficacy and safety of transurethral blue laser vaporization of the prostate, transurethral resection of the prostate (TURP) or plasmakinetic resection of the prostate in the treatment of benign prostatic hyperplasia (BPH). Methods The domestic and foreign clinical studies on transurethral blue laser vaporization of the prostate (observation group), TURP or plasmakinetic resection of the prostate (control group) in the treatment of BPH during Jan. 2015 and Mar. 2025 were retrieved. The data were extracted with Cochrane systematic review method. The operation time, decrease in hemoglobin, bladder irrigation time, catheter indwelling time, total complication rate, retrograde ejaculation rate and urinary incontinence rate of the two groups were compared with RevMan 5.3.0 statistical software. Results A total of 5 Chinese studies involving 491 patients (248 in the observation group and 243 in the control group) were included in the Meta-analysis. Compared with the control group, the observation group had shorter operation time [MD=-20.80, 95%CI:-26.88—-14.72, P＜0.00001], less decrease in hemoglobin [MD=-10.61, 95%CI: -20.21—-1.01, P=0.03], shorter bladder irrigation time [MD=-17.85, 95%CI: -32.62—-3.09, P=0.002], shorter catheter indwelling time [MD=-1.71, 95%CI: -2.81—- 0.62, P=0.002], lower total complication rate [OR=0.11, 95%CI: 0.06—0.21, P＜0.00001], lower retrograde ejaculation rate [OR=0.05, 95%CI: 0.02—0.16, P＜0.00001] and lower urinary incontinence rate [OR=0.24, 95%CI: 0.07—0.79, P=0.02]. There were no significant differences in other complications between the two groups (P＞0.05). The international erectile function score (IIEF-5) of the observation group was significantly higher than that of the control group [MD=1.87, 95%CI:1.16—2.57, P＜0.00001]. There were no significant differences in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax) and post-voiding residual (PVR) between the two groups (P＞0.05). Conclusion All three surgical procedures can effectively improve the lower urinary tract symptoms of BPH patients. Compared with TURP or plasmakinetic resection of the prostate, transurethral blue laser vaporization of the prostate has obvious advantages in terms of perioperative recovery, reduction of total complications, urinary incontinence and retrograde ejaculation rates, and preservation of sexual function.

Objective The purpose of this study is to investigate the expression of histone lysine-specific demethylase 1 (KDM1A) and ubiquitin carboxyl-terminal hydrolase L3 (UCHL3) in thyroid cancer (TC) tissue and its relationship with clinical features and prognosis. Methods 94 TC patients diagnosed and treated at the Third Hospital of Heilongjiang Province from January 2017 to January 2019 were retrospectively selected as the study subjects. Immunohistochemistry was used to detect the expression of KDM1A and UCHL3 in tissues. Spearman correlation analysis was used to investigate the correlation between KDM1A and UCHL3. Kaplan-Meier survival curve was used to analyze the relationship between the levels of KDM1A and UCHL3 and the 5-year progression-free survival rate of TC patients. Multivariate COX regression model was used to analyze the prognostic factors of TC patients. Results The positive rates of KDM1A (68.09％) and UCHL3 (65.96％) in cancer tissues were higher than those in adjacent tissues(10.64％,8.51％),and the differences were statistically significant(x2=64.984,66.369,all P<0.001). The protein expression of KDM1A and UCHL3 was significant protein correlation (r=0.714,P<0.001). The positive rates of KDM1A (87.50％,90.91％) and UCHL3 (85.00％,87.88％) in TNM stage Ⅲ～Ⅳ and lymph node metastatic TC cancer tissues were higher than those in stage Ⅰ～Ⅱ(53.70％,53.85％)and non-lymph node metastatic(55.74％,54.10％) cancer tissues,and the differences were statistically significant(x2=9.985～12.191,all P<0.001). The 5-year progression-free survival rates of TC patients in the KDM1A positive and negative groups were 62.50％ (40/64) and 86.67％ (26/30),with significant differences,the 5-year progression-free survival rates of UCHL3 positive and negative patients were 58.06％ (36/62) and 90.63％ (29/32),with significant differences (Log-Rankx2=5.670,9.724,P=0.017,0.002). KDM1A positive,UCHL3 positive,TNM stage Ⅲ～Ⅳ,lymph node metastasis were risk factors affecting the prognosis of TC patients (Waldx2=1.315～1.697,all P<0.001). Conclusion KDM1A and UCHL3 are upregulated in TC,and played a pro-cancer role. They are new tumor markers for evaluating the prognosis of TC patients.

X-linked adrenoleukodystrophy(X-ALD) is an inherited progressive neurometabolic disorder caused by mutations in the ATP-binding cassette subfamily D member 1(ABCD1) gene. The encoded ALD protein dysfunction leads to the accumulation of very-long-chain fatty acids(VLCFA). X-ALD is classified according to its clinical characteristics into childhood cerebral ALD, adolescent cerebral ALD, adult cerebral ALD, adrenomyeloneuropathy(AMN), pure adrenocortical insufficiency, and an asymptomatic phenotype, all of which can present with a variety of neurologic manifestations. In this study, we retrospectively analyzed the clinical manifestations, laboratory findings, genetic test results, and follow-up data of four patients with X-ALD, and investigated the clinical features and pathogenicity of the identified gene mutations. All four patients initially presented with adrenocortical insufficiency(Addison′s disease) and received glucocorticoid replacement therapy. Subsequently, all developed neurologic signs and symptoms with rapid progression. The final diagnosis was confirmed based on elevated VLCFA levels, brain magnetic resonance imaging(MRI) findings, and genetic analysis. Notably, a deletion mutation in Exon 10 of the ABCD1 gene was identified in one case for the first time. We report four cases of X-ALD presenting with adrenocortical insufficiency as the initial symptom, and briefly review the relevant literature to analyze the relationship between linical phenotypes and genetic loci, aiming to provide a reference for early diagnosis and treatment of the disease, and to reduce the risk of misdiagnosis and missed diagnosis.

Objective:To investigate and analyze basic status of radiotherapy units in Hebei Province in 2024.Methods:Led by the Fourth Hospital of Hebei Medical University, the Radiation Oncology Branch of the Hebei Medical Association, and the Radiation Oncology Expert Committee of the Hebei Society of Clinical Oncology, a province-wide survey was conducted using structured questionnaires.

Collected data were summarized and descriptively analyzed comparing with a 2013 survey of radiotherapy in Hebei Province.Results:All 158 radiotherapy institutions across Hebei Province participated in the survey. A total of 2273 radiotherapy professionals were reported, including 1317 radiation oncologists (57.94%), 332 medical physicists (14.61%), 71 radiotherapy engineers (3.12%), and 553 radiotherapy technologists (24.33%). The number of radiotherapy devices significantly increased from 121 in 2013 to 237 in 2024, including 68 domestic radiotherapy equipment. The current inventory includes 195 medical linear accelerators (2.61 units per million population), 2 cobalt-60 units, 27 afterloading machines, 9 tomotherapy (TOMO) systems, 3 CyberKnife units, and 1 proton therapy system. Three-dimensional conformal radiotherapy and stati intensity-modulated radiotherapy have been widely adopted across the province, while advanced techniques such as volumetric-modulated arc therapy, stereotactic body radiotherapy, and respiration-gated technology, and respiratory gating are gradually being implemented.Conclusions:In recent years, the configuration of radiotherapy personnel in Hebei Province has become more balanced, and the availability of precision radiotherapy equipment has significantly improved. There is a growing trend in the adoption of domestically manufactured radiotherapy equipment, marking substantial progress in the development of radiation oncology services in the region.

Pancreatic duct stents are essential devices for managing chronic pancreatitis,ductal strictures,and postoperative fistula.Conventional plastic and metal stents effectively facilitate pancreatic drainage but often cause infection,restenosis,or migration upon long-term implantation.An ideal stent should provide excellent biocompatibility,efficient drainage,and controllable biodegradation.With advances in material science and medical-engineering integration,stent technology has evolved from inert implantation to intelligent degradation.Biodegradable polymers and metals,particularly magnesium alloys(Mg-Zn-Mn),offer tunable mechanical strength,corrosion resistance,and in vivo degradability.Mg-2Zn-1.0Mn alloy achieves balanced strength and corrosion control through compositional optimization and surface modification.Polymeric stents such as polylactic acid and polydioxanone demonstrate favorable drainage and avoid secondary removal.Composite biodegradable stents,exemplified by the multi-rate ARCHIMEDES model,have received international approval.Supported by 3D printing and smart functionalization-such as drug-eluting or shape-memory designs-next-generation pancreatic stents may achieve integrated functions of support,repair,and tumor inhibition.Future research should emphasize interdisciplinary material design,degradation kinetics under physiological conditions,and long-term biocompatibility to accelerate clinical translation.
