Objective:To establish a risk prediction model based on least absolute shrinkage and selection operator (LASSO) regression for procalcitonin (PCT), milk fat globule-epidermal growth factor 8 (MFG-E8) and CXC chemokine ligand 9 (CXCL9) in elderly patients with liver cancer after transcatheter arterial chemoembolization (TACE) .Methods:A total of 150 elderly patients with liver cancer who underwent TACE treatment in Shishi City Hospital, Fujian Province and 910th Hospital of the Chinese People's Liberation Army Joint Logistic Support Force from August 2020 to August 2023 were selected as the study subjects. Patients with infection after TACE were included in the infected group and those without infection were included in the non-infected group according to whether the patients had infection during the postoperative hospitalization. The baseline data of patients were collected and compared. LASSO regression was used to screen the factors that may affect the infection after TACE in elderly patients with liver cancer and binary logistic regression analysis was performed. According to the results of regression analysis, a nomogram model was constructed based on the regression analysis results and the nomogram was internally validated using Bootstrap and receiver operator characteristic (ROC) curves.Results:There were 18 cases of infection in 150 elderly patients with liver cancer after TACE, with an incidence of 12.00%. There were statistically significant differences in focal rupture and bleeding ( χ2=5.92, P=0.015), ascites ( χ2=6.70, P=0.010), skin or mucosal damage ( χ2=6.67, P=0.010) between the infected group ( n=18) and the non-infected group ( n=132). The levels of serum PCT [ (1.17±0.32 ) μg/L vs. (0.91±0.14) μg/L], MFG-E8 [ (194.29±45.85) pg/ml vs. (158.76±28.63) pg/ml] and CXCL9 [ (948.49±52.38) pg/ml vs. (886.05±50.07) pg/ml] were higher than those in the non-infected group, with statistically significant differences ( t=4.13, P<0.001; t=4.55, P<0.001; t=4.94, P<0.001). Four factors related to infection after TACE intervention in patients with liver cancer were finally selected by LASSO regression model, skin or mucosal damage, PCT, MFG-E8, CXCL9 levels. Binary logistic regression analysis showed that skin or mucosal damage ( OR=13.48, 95% CI: 1.29-140.47, P=0.030), high levels of serum PCT ( OR=1.13, 95% CI: 1.05-1.22, P=0.001), MFG-E8 ( OR=1.04, 95% CI: 1.01-1.07, P=0.003), CXCL9 ( OR=1.05, 95% CI: 1.02-1.08, P=0.001) were risk factors for infection after TACE in elderly patients with liver cancer. Based on skin or mucosa damage, PCT, MFG-E8 and CXCL9, a nomogram prediction model for postoperative infection in elderly patients with liver cancer after TACE intervention was established. Calibration curve showed that the C-index of postoperative infection predicted by the nomogram model in elderly patients with liver cancer after TACE intervention was 0.939, indicating the model had good discrimination. ROC curve analysis showed that the area under the curve (AUC) predicted by the nomogram model for infection after TACE intervention in elderly patients with liver cancer was 0.960 (95% CI: 0.926-0.995, P<0.001), which had certain predictive value. The specificity, sensitivity and Youden index were 0.864, 0.944 and 0.808, respectively. Conclusions:Skin or mucosal damage, high levels of serum PCT, CXCL9 and MFG-E8 are closely related to postoperative infection in elderly patients with liver cancer after TACE, and the prediction model constructed based on this has better predictive performance for postoperative infection.

Eight new diterpenoids, Isodons A-H (1-8), comprising seco-abietane and abietane-type structures, together with 13 known analogues (9-21), were isolated from Isodon lophanthoides (Buch.-Ham. ex D. Don) Hara. The compounds (+)-3/(-)-3, (+)-4/(-)-4, and (+)-5/(-)-5 were identified as three enantiomeric pairs. The planar structures and absolute configurations of 1-8 were determined through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), 1D & 2D nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray diffraction crystallography. A cholesterol 7α-hydroxylase (Cyp7a1) luciferase reporter assay revealed significant anti-cholestatic activities for compounds 1, (+)-4, 6, 7, 12-14, and 16. Additionally, compound 6 demonstrated anti-cholestatic effects through the farnesoid X receptor (FXR)-associated signaling pathways in vitro and in vivo. These findings suggest potential applications for I. Lophanthoides in pharmaceutical development.

Objective:To evaluate the clinical efficacy and safety of stereotactic surgery in patients with refractory mental disorders.Methods:A retrospective analysis was performed; clinical data, postoperative complications and medication intake of 149 patients with refractory mental disorders accepted stereotactic surgery in Department of Neurosurgery, People's Hospital, Wuhan University from August 2019 to December 2023 were collected. Outcomes were assessed at 1, 6, 12, and 24 months after surgery by Clinical Global Impression-Global Improvement (CGI-GI). Before and 1, 6, and 12 months after surgery, severities were assessed by Clinical Global Impression-Severity of Illness (CGI-SI); cognition was assessed by Montreal Cognitive Assessment (MoCA); positive and negative symptoms were evaluated by Positive and Negative Symptom Scale (PANSS); psychotic symptoms were evaluated by Brief Psychiatric Rating Scale (BPRS) and Symptom Checklist 90 (SCL-90); obsessive-compulsive symptoms, depressive symptoms, anxiety symptoms and manic symptoms were assessed by Yale-Brown Obsessive-Compulsive Symptoms Scale (Y-BOCS), Beck Depression Inventory (BDI)-II, Beck Anxiety Inventory (BAI), and Young Mania Rating Scale (YMRS), respectively; social functioning and quality of survival were evaluated by Social Disability Screening Schedule (SDSS) and World Health Organization Quality of Life-Bref Form (WHOQOL-BREF).Results:(1) Increased sleep was noted in 47 patients and fatigue in 38 patients within 1 week after surgery. Behavioral laziness and emotional apathy were still presented at 1 month after surgery in 6 patients, and complications disappeared in the rest patients. Mildly reduced initiative was presented at 12 months after surgery in 5 patients. (2) CGI-GI indicated that 149 patients were followed up 1 month after surgery with an overall efficiency of 85.90%; 135 patients were followed up at 6 months after surgery with an overall efficiency of 83.21%, 106 patients were followed up at 12 months after surgery with an overall efficiency of 79.24%, and 63 patients were followed up at 24 months after surgery with an overall efficiency of 80.95%. (3) Compared with those before surgery, significantly lower BPRS scores, significantly lower PANSS positive, negative, and overall scores, statistically lower BAI, BDI-II, YMRS, and MOAS scores, significantly lower Y-BOCS obsessional thinking, compulsive behavior and total scores, significantly higher WHOQOL-BREF (physical and psychological domains) scores, and significantly lower SDSS and SCL-90 scores were noted in patients at 1, 6, and 12 months after surgery ( P<0.05). (4) At 12 months after surgery, withdrawal drug was noted in 13 patients, reduced drug in 38, same dose in 52, and increased drug in 2 patients. Conclusion:Stereotactic surgery can obviously improve obsession, anxiety, depression, mania and aggression, and modify social functioning and quality of survival in patients with refractory mental disorders, enjoying good safety.

Oromandibular dystonia (OMD) is a type of Meige syndrome, which is characterized by involuntary repeated abnormal postured contraction of bilateral masticatory muscles, orbicularis oris muscles and mimetic muscles. Involved nerves are buccal branch of facial nerve, mandibular marginal branch and/or mandibular branch of trigeminal nerve. At present, the pathogenesis of OMD is still unclear, and no specific treatment for OMD is noted. This article reviews the pathogenesis, clinical manifestations, classifications, diagnoses, differential diagnoses and treatments of oromandibular dystonia in order to strengthen the understanding of the disease.
