ObjectiveTo investigate the differences in clinicopathological features and prognosis between patients with drug-induced vanishing bile duct syndrome （VBDS） and those with VBDS induced by autoimmune liver disease， and to summarize the key points for clinical differentiation. MethodsA total of 67 patients who were diagnosed with VBDS by liver biopsy in The First Affiliated Hospital of Soochow University and Wuxi Fifth People’s Hospital from January 2018 to June 2024 were enrolled as subjects， among whom 18 had drug-induced VBDS （D-VBDS group） and 49 had VBDS induced by autoimmune liver disease （A-VBDS group）. Related data were collected， including general information， clinical symptoms and signs， laboratory markers， liver pathomorphological features， and prognosis. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsAmong the 67 VBDS patients， female patients accounted for a higher proportion （80.60%）， and the patients aged 40 — 59 years accounted for 55.22%； there were 18 patients （26.87%） with D-VBDS and 49 patients （73.13%） with A-VBDS. Yellow urine （83.58%） was the most common clinical symptom in VBDS patients， followed by fatigue （64.18%）， poor appetite （64.18%）， jaundice of the sclera （62.69%）， abdominal distension （23.88%）， pruritus （23.88%）， nausea and vomiting （20.90%）， and fever （13.43%）. Compared with the D-VBDS group， the A-VBDS group had a significantly higher degree of plasma cell infiltration and a significantly lower degree of canalicular bile plugs （χ²=14.186， 6.568， both P<0.05）. Compared with the A-VBDS group， the D-VBDS group had significantly higher peak levels of alanine aminotransferase， total bilirubin， direct bilirubin， and indirect bilirubin （Z=-2.546， -2.957， -2.628， -2.772， all P<0.05）. Compared with the D-VBDS group， the patients in the A-VBDS group were more likely to develop liver cirrhosis （χ²=4.682， P=0.030）. ConclusionThe levels of alanine aminotransferase and bilirubin and liver pathomorphological features are objective indicators for differentiating D-VBDS from A-VBDS， and they are of great importance for clarifying diagnosis and determining the degree of liver injury. Patients with A-VBDS are more likely to develop liver cirrhosis.

The aim of this research was to investigate the mechanism of chelidonine on H2 O2-in-duced inflammatory injury in porcine intestinal epithelial cells(IPEC-J2)through transcriptome sequencing.IPEC-J2 cells in the logarithmic growth phase were divided into the blank group(K group),H2O2 group(S group)and chelidonine group(L group),with three replicates in each group.Total RNA was isolated from each group for the purpose of constructing a sequencing li-brary.The assembled data underwent functional annotation,differential gene analysis,as well as GO and KEGG enrichment analyses.qPCR was used to confirm the expression of key differentially expressed genes(DEGs),and ELISA was utilized to assess the effect of chelidonine on the permea-bility of IPEC-J2 cells.The results indicated that the sequencing data met the necessary criteria and demonstrated a strong correlation between samples.The GO functional annotation results suggest that the intervention effects of chelidonine involve biological processes such as oxidative stress re-sponse and G2/M phase transition regulation of the mitotic cycle,and are closely associated with molecular functions,such as transmembrane transport activity.The KEGG enrichment analysis indicates that following H2 O2 treatment,DEGs in IPEC-J2 cells are predominantly enriched in the p53 signaling pathway,the coagulation cascade,the FoxO signaling pathway,and various other sig-naling pathways.Following pretreatment with chelidonine,the DEGs exhibit significant enrichment in several signaling pathways related to inflammation,including the TNF signaling pathway,syn-aptic vesicle cycle,and IL-17 signaling pathway.The results of qPCR were consistent with the se-quencing results.Chelidonine has also been found to effectively inhibit LDH release,elevate GLN content,and decrease DOA content.In conclusion,it can be seen that chelidonine can reduce cell permeability and alleviate H2 O2-induced inflammatory injury in IPEC-J2 cells by modulating in-flammation-related pathways such as the TNF signaling pathway.

Objective:To investigate the prognostic impact of perineural invasion in patients with stageⅢ colon cancer and to clarify its guidance value for the duration of postoperative adjuvant chemotherapy.Methods:This study employed a retrospective cohort study method. It analyzed 426 patients with stageⅢ colon cancer who underwent radical surgery at Sun Yat-sen University Cancer Center and Longyan First Affiliated Hospital of Fujian Medical University, between April 2008 and June 2020. Inclusion criteria: patients received at least 3 months of adjuvant CapeOX therapy post-surgery, had complete pathological data, and were followed up for at least 12 months after the last chemotherapy. Among these patients, 231 were male, the median age was 59 (50~67) years, and 263 tumors were located in the right-sided colon. Postoperative pathology indicated that 107 cases (25.12%) had neural invasion, and 131 patients (30.75%) had vascular tumor thrombus. All patients received at least 4 cycles of postoperative CapeOX adjuvant chemotherapy, with 193 patients receiving 8 cycles and 233 patients receiving 4 to 7 cycles of adjuvant chemotherapy. The study analyzed the impact of neural invasion status and the duration of adjuvant chemotherapy on disease-free survival (DFS). Furthermore, within subgroups stratified by different risk levels (referencing the criteria proposed by the IDEA study: high risk: T4, N2 or T4N2; low risk: T3N1) and different neural invasion statuses, the impact of the duration of adjuvant chemotherapy on prognosis was analyzed.Results:The median follow-up time for the entire cohort was 94.00 months (55.27-128.80 months). Multivariate Cox analysis indicated that pathological T stage T4 (HR = 2.457, 95%CI: 1.499-4.029, P<0.001) and postoperative pathological confirmation of perineural invasion (HR = 2.465, 95% CI: 1.519-4.000, P<0.001) were independent adverse prognostic factors for 5-year DFS. In the perineural invasion-positive group, the 5-year DFS for patients who received 8 cycles of postoperative adjuvant CapeOX chemotherapy was 86.90%, compared to 58.22% for those who received 4-7 cycles, with statistically significant differences (both P<0.05). In the perineural invasion-negative group, the 5-year DFS for patients who received 8 cycles was 88.66%, compared to 90.99% for those who received 4-7 cycles, with no statistically significant differences ( P=0.929). Among IDEA high-risk patients with perineural invasion, the 5-year DFS was 91.81% for those who received 8 cycles versus 50.66% for those who received 4-7 cycles, showing a statistically significant difference ( P=0.003). In IDEA high-risk patients without perineural invasion, the 5-year DFS for those who received 8 cycles was 82.28% compared to 87.32% for those who received 4-7 cycles, with no statistically significant difference ( P=0.806). In the IDEA low-risk patients, no differences were observed in the 5-year DFS between patients receiving 8 cycles and those receiving 4-7 cycles of adjuvant CapeOX chemotherapy in both perineural invasion-positive and negative subgroups (both P>0.05). Conclusion:Perineural invasion serves as a significant prognostic factor for 5-year DFS in stage Ⅲ colon cancer patients who have undergone radical surgery and postoperative adjuvant chemotherapy. It can also be considered an important reference factor in deciding the duration of postoperative adjuvant chemotherapy.

Objective:To evaluate the efficacy of intraoperative sliding CT assisted deep brain stimulation of subthalaminal nucleus (STN-DBS) in short-term motor improvement and its influencing factors in patients with Parkinson's disease (PD) under general anesthesia.Methods:The cohort consisted of 48 PD patients accepted STN-DBS in Department of Neurosurgery, First Affiliated Hospital of Zhengzhou University from June 2021 to June 2023, including 21 patients accepted STN-DBS under general anesthesia and 27 patients accepted STN-DBS under local anesthesia. STN-DBS was performed in the CT operating room and intraoperative CT was used to confirm the electrode position. Regular program-controlled follow-up for over one year in Out-patient Clinic was applied after discharge. Operation time, complications, stimulus-related adverse events, unified Parkinson's disease rating scale (UPDRS)-Ⅲ score and UPDRS-Ⅲ improvement rate at medicine-off (Med-off) stage/DBS-on stage 1 year after operation, and UPDRS-Ⅲ score and UPDRS-Ⅲ improvement rate at medicine-on (Med-on) stage/DBS-on stage 1 year after operation, and levodopa equivalent daily dose (LEDD) and LEDD reduction were compared between the two groups. Spearman rank correlation analysis or Pearson correlation analysis were used to investigate the correlation between short-term motor improvement ([UPDRS-Ⅲ score at Med-off stage before operation-UPDRS-Ⅲ score at Med-off stage/DBS-on stage 1 year after operation]/UPDRS-Ⅲ score at Med-off stage before operation×100%) and clinical data in PD after STN-DBS under general anesthesia.Results:The operation time of general anesthesia group was (1.9±0.5) h, and that of local anesthesia group was (2.6±0.8) h, with significant difference ( P<0.05). During the 1-year follow-up, no significant difference in incidence of adverse reactions, UPDRS-Ⅲ score improvement rate at Med-on and Med-off stages, LEDD and LEDD reduction was noted between the two groups ( P>0.05). In the general anesthesia group, the short-term motor improvement after STN-DBS was negatively correlated with age or gender ( P>0.05), but positively correlated with maximum improvement rate of preoperative UPDRS-Ⅲ score ( r=0.840, P<0.001). Conclusion:For patients who cannot tolerate local anesthesia, DBS under general anesthesia is also safe and effective.

Objective:To investigate the characteristics of β and γ oscillations in Parkinson's disease (PD) patients with levodopa-induced dyskinesia (LID).Methods:Seventeen patients with advanced idiopathic PD received subthalamic nucleus deep brain stimulation (STN-DBS) from August 2019 to June 2021 at Department of Neurosurgery, First Affiliated Hospital of Zhengzhou University were enrolled; 11 patients were without LID before surgery (PD group) and 6 patients were with LID before surgery (LID group). Preoperative electrophysiological data of the STN, including Area under power spectral density (PSD-AUC), burst amplitude and duration of β and γ oscillations, were compared between the two groups.Results:PSD-AUC of β oscillation at 25-35 Hz in the PD group (60.39±1.00) was significantly increased compared with that in the LID group (54.33±0.55), whereas the PSD-AUC of γ oscillation at 65-85 Hz in the LID group (97.31±1.84) was significantly increased compared with that in the PD group (41.52±7.42, P<0.05). The aburst mplitude and duration of β oscillation in the PD group were significantly increased compared with those in the LID group ([8.52±1.00] au] vs. [1.09±0.13] au, [13 344±2 069] ms vs. [1 442±128] ms, P<0.05), while the burst amplitude and duration of γ oscillation in the LID group were significantly higher than those in the PD group ([5.03±0.55] au vs. [0.14±0.01] au, [12 276±5 011] ms vs. [1 741±233] ms, P<0.05). Conclusion:The imbalance of β-γ oscillations in the STN is associated with LID pathophysiology.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.
