Objective:To evaluate the application value of artificial intelligence (AI) and robot of stereotactic surgery (ROSS)-assisted ultra-early thalamic hematoma drainage in elderly patients with minor thalamus and internal capsule hematoma (TICH) and severe hypoperfusion in the internal capsule area.Methods:A retrospective cross-sectional study was performed; 278 patients with TICH and severe hypoperfusion in the internal capsule area identified by AI medical imaging diagnostic system were enrolled from Department of Neurosurgery, Xingtai Central Hospital from January 2023 to August 2024. Among them, 134 patients (study group) received AI and ROSS-assisted ultra-early thalamic hematoma drainage, and 144 patients (control group) received drug treatment. Differences in baseline data and therapy efficiency between the two groups of patients were compared. Multivariate Logistic regression analysis was used to screen the independent influencing factors for prognosis in the study group 180 days after onset (good prognosis: modified Rankin scale scores of 0-3).Results:Compared with the control group, the study group had significantly higher Glasgow coma scale (GCS) score and regional cerebral blood flow (rCBF) in the internal capsule area 14 days after onset, and statistically higher therapy efficiency and good prognosis rate 180 days after onset ( P<0.05). In the study group, 84 patients had a good prognosis and 50 had a poor prognosis 180 days after onset; compared with the good prognosis group, the poor prognosis group had significantly higher proportion of patients with hyper-homocysteinemia history, lower GCS score on admission, larger volume of thalamic hematoma, higher proportions of patients with combined intraventricular hemorrhage and shunt-dependent hydrocephalus, and lower rCBF in the internal capsule area on admission ( P<0.05). Multivariate Logistic regression analysis showed that thalamic hematoma volume ( OR=2.527, 95% CI: 1.504-4.247, P<0.001), combined intraventricular hemorrhage ( OR=2.325, 95% CI: 1.460-3.703, P<0.001), shunt dependent hydrocephalus ( OR=2.371, 95% CI: 1.267-4.078, P=0.006), and rCBF in the internal capsule area on admission ( OR=0.672, 95% CI: 0.314-1.025, P<0.001) were independent risk factors for prognosis of patients in the study group. Conclusion:AI and ROSS-assisted ultra-early thalamic hematoma drainage is effective for elderly patients with minor TICH and severe hypoperfusion in the internal capsule area; patients with large thalamic hematoma volume, combined intraventricular hemorrhage, shunt-dependent hydrocephalus, and low rCBF in the internal capsule area on admission are prone to have a poor prognosis.

Objective To evaluate the clinical value of bedside ultrasonographic measurement of optic nerve sheath diameter(ONSD)combined with serum matrix metalloproteinase-9(MMP-9)and neutrophil-to-lymphocyte ratio(NLR)in assessing postoperative intracranial hypertension in patients with severe traumatic brain injury.Methods A total of 100 patients with severe traumatic brain injury were enrolled as study subjects.According to postoperative intracranial pressure status,the patients were divided into normal group(n=33)and elevated group(n=67).ONSD,MMP-9 and NLR lev-els were compared between the two groups.The correlations among ONSD,serum MMP-9 and NLR in the elevated group were analyzed.The influencing factors of postoperative intracranial hypertension in patients with severe traumatic brain injury were evaluated.Receiver operating characteristic(ROC)curve analysis was performed to assess the diagnostic value of ONSD combined with serum MMP-9 and NLR for postoperative intracranial hypertension.Results ONSD,serum MMP-9 and NLR levels were significantly higher in the elevated group than those in the normal group(P＜0.05).ONSD was positively correlated with MMP-9(r=0.367,P=0.002),ONSD was positively correlated with NLR(r=0.419,P＜0.01),and MMP-9 was positively correlated with NLR(r=0.324,P=0.007).Elevated ONSD,serum MMP-9 and NLR were risk factors for increased in-tracranial pressure after severe craniocerebral injury surgery(P＜0.05).The area under the curve for evaluation of postoperative intracranial pressure increase in patients with severe craniocerebral in-jury by combination of ONSD,serum MMP-9 and NLR was 0.976(95％CI,0.952 to 1.000),the sensitivity was 91.04％,and the specificity was 93.94％.The combined evaluation value of ONSD,serum MMP-9 and NLR for increased intracranial pressure after surgery in patients with severe craniocerebral injury was higher(Zcombined with-ONSD=3.453,P=0.001,Zcombined with-MMP-9=3.637,P＜0.001,Zcombined with-NLR=2.654,P=0.008).Conclusion In patients with increased intracra-nial pressure after severe craniocerebral injury surgery,their levels of ONSD,serum MMP-9 and NLR increase,and the increase of the three indicators will increase the risk of increased intracranial pressure after surgery.The combined detection of the three indicators has certain value in evaluating the increase of intracranial pressure in patients after surgery.

Objective:Small cell lung cancer (SCLC) is a highly malignant tumor with a high risk of brain metastasis (BMs). The purpose of this study was to evaluate the clinical factors affecting the occurrence of BMs in patients with stage IIB-IIIB SCLC who achieved complete remission (CR) after thoracic radio-chemotherapy.Methods:Clinical data of 191 patients with stage IIB-IIIB SCLC who achieved CR after thoracic radio-chemotherapy in Zhejiang Cancer Hospital from January 2009 to April 2016 were retrospectively analyzed. Common clinical factors related to the risk of BMs, including gender, age, thoracic radiotherapy dose, combined mode of radiotherapy and chemotherapy, pretreatment serum NSE and LDH, whether PCI was performed, TMN stage and PS score, were analyzed using log-rank method for univariate analysis, COX regression method for multivariate analysis and Kaplan-Meier method to plot the survival curve.Results:Univariate analysis showed that pretreatment LDH level≥240IU, pretreatment NSE ≥17 ng/ml and no PCI were positively correlated with the risk of BMs (all P＜0.05). Multivariate analysis showed that the risk of BMs was only positively correlated with pretreatment LDH≥240IU [HR: 1.90, 95%CI(1.07-3.37), P=0.029], and no PCI [HR:2.08, 95%CI(1.17-3.72), P=0.013]. Conclusion:Pretreatment serum LDH levels provide important value for predicting the risk of BMs in patients with stage IIB-IIIB SCLC who achieve CR after thoracic radio-chemotherapy.

Objective　To evaluate the role of ultrasound in evaluating hemodynamic parameters for post-operative patients with ocular ischemia syndrome.Methods　 to direction of ophthalmic artery blood flow，68 cases of OIS patients were divided into forward blood flow group（n=41） and reverse blood flow group（n=27）. The carotid stenosis rate and PSV using ultrasound and BCVA were detected.Results　Before operation，carotid artery stenosis rate of forward blood flow group was significantly lower than reverse blood flow group（P<0.05） Before and after operation，posterior ciliary artery PSV and BCVA of forward blood flow group was obviously higher than reverse blood flow group（P<0.05）. The ophthalmic artery，posterior ciliary artery and central retinal artery PSV after operation in the two groups were significantly higher than those before operation（P<0.05）. BCVA after operation in forward blood flow group was significantly higher than before operation（P<0.05）.Conclusion　Ultrasound can accurately evaluate carotid artery stenosis，PSV，and provide reference value for evaluating hemodynamic changes.

Objective To systematically evaluate the efficacy and safety of craniotomy and decompressive craniectomy in the treatment of acute subdural hematoma.Methods A systematic search was performed in PubMed,EMbase,the Cochrane Library,Web of science,China National Knowledge Infrastructure (CNKI),WanFang Data,and CBM databases up to June 2018 for the studies that provided comparisons between craniotomy hematoma evacuation and decompressive craniectomy for acute subdural hematoma.For the two categorical variables,the Odds Ratio (OR) and its 95％ Confidence Interval (95％ CI) are used.Two researchers independently screened the literature,extracted the data,and evaluated the risk of bias of the included studies.The meta analysis was performed using Stata/SE 12.0 software.Results A total of 8 studies were included in the meta analysis,of which 828 patients underwent craniotomy,and 663 patients underwent decompressive craniectomy.Meta analysis results showed that patients receiving decompressive craniectomy had a significantly lower Glasgow Coma Scale (GCS) when they first had symptoms.The residual rate of acute subdural hematoma in the decompressive craniectomy group was significantly lower than that in the craniotomy group (P =0.015),but there was no significant difference in the rate of reoperation.The incidence of poor outcome at following was lower in the craniotomy group compared with decompressive craniectomy group (50.1％ vs 60.1％;P =0.003).Similarly,the mortality of the craniotomy group was lower than that of the decompressive craniectomy group (P =0.002).Conclusions Decompressive craniectomy may be the first choice for acute subdural hematoma,but the study is influenced by many factors and is not sufficient to provide definitive evidence.
