Objective:To analyze the effects of enteral nutrition on interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),pulmonary surfactant protein A(SPA),and clinical pulmonary infection score(CPIS)in patients with hospital-acquired pneumonia(HAP)after stroke.Methods:A retrospective review was conducted of the clinical records of 90 patients with hospital-acquired pneumonia following stroke admitted to the Geriatric Medicine Department of Nanjing Brain Hospital between January 2022 and February 2023.Participants were divided into a control group and a study group based on the use of enteral nutrition,with 45 patients in each group.The control group received standard treatment(conventional stroke management combined with meropenem for infection control),while the study group received standard treatment supplemented with enteral nutrition.Within the study group,cases were classified as non-severe(n=33)and severe(n=12)based on disease severity.Peripheral blood levels of IL-6,TNF-α,and SPA,alongside the Clinical Pulmonary Infection Score(CPIS),were collected.Results:Before treatment,baseline data between the study group and control group showed no statistically significant differences,with no significant differences in IL-6,TNF-α,SPA,or CPIS scores between groups(P>0.05).Following enteral nutrition therapy,the study group exhibited significantly lower levels of IL-6,TNF-α,and SPA,as well as lower CPIS scores compared to the control group,with statistically significant differences(P<0.05).Before treatment,statistically significant differences existed between severe and non-severe cases within the study group for IL-6,TNF-α,SPA,and CPIS scores(P<0.05).After therapy,no statistically significant differences were observed between non-severe and severe patients in the study group for IL-6,TNF-α,SPA levels,or CPIS scores(P>0.05).Patients in the study group demonstrated shorter symptom resolution times,overall hospital stays,and recovery times for IL-6,TNF-α,and SPA levels compared to the control group,with all differences being statistically significant(P<0.05).Conclusion:Enteral nutrition significantly reduces peripheral blood levels of IL-6,TNF-α,and SPA in patients with post-stroke HAP,lowers CPIS scores,shortens symptom resolution time and overall hospital stay,and accelerates recovery of IL-6,TNF-α,and SPA levels.

Objective To analyze the relationship of the volume of 87 brain regions with postnatal age and neurobehavior in full-term neonates.Methods A total of 75 full-term newborns[gestational age(39.38±1.22)weeks;male/female(51/24);postnatal age(11.11±6.67)days]without abnormalities on brain MRI(three-dimensional T1-weighted imaging,3D T1WI)at our hospital between November 2010 and September 2017 were retrospectively included.Based on the template of 87 brain regions,the neonatal brains were divided into 87 brain regions and their volumes were calculated by using V-shape Bottleneck network(VB-Net)deep learning segmentation technique,Pearson partial correlation and regression analysis were used to explore the relationship of the volume of each brain region with postnatal age and neurobehavioral scores.Results After adjusting for gestational age,birth weight,head circumference,body length and sex,66.7％of the regional brain volumes(58/87 brain regions)significantly increased with the postnatal age(correlation coefficient r:0.2-0.7,P＜0.05).The volumes of gray matter in bilateral lentiform nucleus,left caudate nucleus,right occipital lobe,right inferior temporal lobe,and bilateral anterior temporal lobe strongly correlated with the postnatal age(r＞0.50,P＜0.05).The gray matter volume of the right occipital lobe linearly increased with age(slope:100.67),and was positively correlated with behavioral scores(r=0.324,P＜0.01).Conclusion Most of regional brain volumes increase with the postnatal age during the neonatal period,and the fastest growth occurs in primary sensorimotor-related brain regions,presenting the spatial heterogeneity.Partial brain region grows with the development of behavioral ability.

Objective: To analyze the safety and effectiveness of different types of stents with the treatment of vertebraebasilar artery dissection aneurysms(VBADA). Methods : The clinical data of 80 patients with VBADA treated by intravascular intervention in the First Hospital of University of Science and Technology of China(Anhui Provincial Hospital) from February 2018 to November 2023 were retrospectively analyzed. Patients were divided into laser engraved stent group(n=34) and braided stent group(n=46) based on the type of stent used. O′Kelly-Marotta(OKM) grade was used to evaluate the embolization effect of aneurysms in DSA images, and a modified Rankin Scale(mRS) score was used to evaluate the clinical prognosis of patients. The baseline data, aneurysm characteristics, intraoperative and perioperative treatment details and postoperative follow-up details between the two groups were compared. Results : There was no significant difference in baseline data, mRS score, ischemic and hemorrhage complications and mortality between the two groups(allP>0.05). Compared with the laser engraved stent group, the mean diameter of aneurysms was larger(P<0.000 1) and the proportion of ruptured aneurysm(P<0.01), parent artery stenosis and beaded vascular lesions(P<0.05) and branch artery dissecting aneurysm were higher(P<0.01) in the braided stent group. Conversely, the proportion of coil-assisted embolization(P<0.000 1) and the immediate aneurysm occlusion rate(OKM C and D)(P<0.000 1) were lower. Finally, 21 patients were obtained by controlling for maximum diameter of aneurysms and whether coil-assisted embolization, the aneurysm occlusion rate half a year later in the braided stent group was higher than that in the laser engraved stent group(P<0.05), but the recurrence rate of postoperative aneurysm was lower than that of laser engraved stent group(P<0.05). It was worth noting that the cure rate and vascular remodeling rate of middle-large size VBADA which the maximum diameter being over 15 mm in the braided stent group reached 72.2%, and the whole effect was ideal. Conclusion Braided stents are relatively safe and effective in the treatment of VBADA and are significantly better than laser engraved stents in reducing VBADA recurrence and remodeling lesion vessels without increasing postoperative complication.

Objective:To analyze the effect and influencing factors of embolotherapy on headache in elderly patients with unruptured intracranial aneurysms.Methods:A retrospective analysis of clinical data of elderly patients(aged&ge;61 years)with unruptured intracranial aneurysms admitted to our hospital from January 2018 to December 2020 was performed.Headache assessment was performed by a quantitative 11-point headache scale in all patients preoperatively and at 6 months after endovascular treatment, and the difference between them was analyzed.Univariate analysis was applied to test the association between headache outcomes and clinical variables.Results:A total of 73 patients(mean age: 68.4 years old; age range: 61-86 years; 47 women)fulfilled the inclusion criteria.There were 53 patients(72.6%)who presented with preoperative headache(headache score&ge;1). Among them, 39 cases(73.6%)had an improvement in headache, 11(20.8%)remained unchanged, and 3(5.7%)aggravated, after endovascular treatment.The average preoperative headache score was 5(4, 6) vs.postoperative 3(1, 4), with statistical significance( Z=-5.036, P=0.000). Only the preoperative headache score was associated with outcomes of headache, and a higher headache score predicted a lack of headache relief( Z=-2.819, P=0.005). Conclusions:Embolotherapy of unruptured intracranial aneurysms can relieve headache in most elderly patients.Preoperative headache severity is correlated with postoperative headache outcomes.

Objective:To observe the short-term efficacy and complications of intracranial wide-necked aneurysms treated by Neuroform Atlas stent-assisted coil embolization, and preliminary explore its safety and effectiveness.Methods:A retrospective analysis was performed. The clinical data of 33 patients with intracranial wide-necked aneurysms, admitted to our hospital from September 2020 to August 2021, were collected. All patients underwent Neuroform Atlas stent -assisted coil embolization, including 28 patients with single stent assisted coil embolization and 5 with double stent assisted embolization. Raymond grading was used to evaluate the degrees of immediate postoperative aneurysm embolization. Modified Rankin scale (mRS) was used to assess the prognoses 3-6 months after surgery. DSA was performed to recheck the recurrence of aneurysms and the patency of the parent artery.Results:DSA immediately after surgery showed that all aneurysms were tightly embolized (Raymond grading I). One patient developed intraoperative thrombosis, and blood flow was restored after tirofiban thrombolytic therapy, without new neurological dysfunction after surgery. Three-6 months after surgery, all patients had a good prognosis; DSA recheck was completed in 21 patients (63.6%), and no stenosis or thrombosis were found in the parent artery and no aneurysm recurrence was noted.Conclusion:The Neuroform Atlas stent-assisted coil embolization in treatment of intracranial wide-necked aneurysms has good efficacy and high safety.

Qing-Fei-Pai-Du decoction (QFPDD) is a Chinese medicine compound formula recommended for combating corona virus disease 2019 (COVID-19) by National Health Commission of the People's Republic of China. The latest clinical study showed that early treatment with QFPDD was associated with favorable outcomes for patient recovery, viral shedding, hospital stay, and course of the disease. However, the effective constituents of QFPDD remain unclear. In this study, an UHPLC-Q-Orbitrap HRMS based method was developed to identify the chemical constituents in QFPDD and the absorbed prototypes as well as the metabolites in mice serum and tissues following oral administration of QFPDD. A total of 405 chemicals, including 40 kinds of alkaloids, 162 kinds of flavonoids, 44 kinds of organic acids, 71 kinds of triterpene saponins and 88 kinds of other compounds in the water extract of QFPDD were tentatively identified via comparison with the retention times and MS/MS spectra of the standards or refereed by literature. With the help of the standards and in vitro metabolites, 195 chemical components (including 104 prototypes and 91 metabolites) were identified in mice serum after oral administration of QFPDD. In addition, 165, 177, 112, 120, 44, 53 constituents were identified in the lung, liver, heart, kidney, brain, and spleen of QFPDD-treated mice, respectively. These findings provided key information and guidance for further investigation on the pharmacologically active substances and clinical applications of QFPDD.

Objective:To investigate the application value of electroencephalogram (EEG) combined with regional cerebral oxygen saturation (rSO 2) in monitoring cerebral perfusion during carotid endarterectomy (CEA). Methods:A retrospective analysis of clinical data of 42 patients with atherosclerotic carotid artery stenosis admitted to and accepted CEA in our hospital from January 2018 to December 2019 was performed. CEA was performed under EEG combined with rSO 2 monitoring. The efficacy and safety of EEG combined with rSO 2 in monitoring cerebral perfusion abnormalities during CEA were analyzed. Results:After carotid artery occlusion, 24 patients (57.1%) had normal EEG and rSO 2; 15 (35.7%) had abnormal changes of EEG, among whom 13 (31.0%) were accompanied by rSO 2 anomaly; 16 (38.1%) had abnormal rSO 2, among whom 13 (31.0%) were accompanied by EEG anomaly. Of these 18 patients with abnormal EEG and/or rSO 2 monitoring, 17 patients recovered after increasing their blood pressure and 1 patient recovered after diverter tube usage. Intraoperative EEG and rSO 2 monitoring results were consistent (Kappa=0.745, P=0.000). The positive rates of combined monitoring, EEG alone or rSO 2 alone were 42.9%, 35.7% and 38.1%, respectively. All patients were evaluated clinically and radiologically before discharge, and no new ischemic lesions or clinical symptoms were found. Conclusions:EEG and rSO 2 monitoring are well consistent in CEA; the combined monitoring can make up for the deficiency of single monitoring to increase surgical safety.

Objective:To observe the short-term efficacy and complications of flow diverter device Tubridge in the treatment of complex intracranial aneurysms, and to summarize the indications and experience of Tubridge in treatment of complex intracranial aneurysms.Methods:Thirty-one patients with complex intracranial aneurysms accepted treatment with assistance of Tubridge in our hospital from January 2020 to December 2020 were enrolled. Raymond grading was used to evaluate the degrees of aneurysm embolization immediately after surgery. Modified Rankin scale (mRS) was used to evaluate the prognoses 6 months after surgery. The embolization of aneurysms was determined in these patients by DSA 6 and 12 months after surgery.Results:Thirty-seven aneurysms were noted in these 31 patients. A total of 32 diverters (Turbridge) were implanted into these 37 aneurysms, and all of which were successfully delivered and released. Thirteen aneurysms were filled with spring coils (8 with Raymond grading I, 2 with Raymond grading II, 3 with Raymond grading III by DSA immediately after surgery), and 24 aneurysms were not filled with spring coils. Postoperative ischemic complications occurred in 1 patient, and no hemorrhagic complications or death were noted. All 31 patients had good prognosis at follow-up. Six months after surgery, DSA re-examination in 24 patients (77.4%) showed that complete occlusion of aneurysms was achieved in 17 patients (70.8%). DSA re-examination 12 months after surgery showed complete occlusion of aneurysms in 19 of the 25 patients (76%).Conclusion:The new domestic flow diverter device Tubridge has a high success rate, less perioperative complications, high safety, and good recovery in the treatment of complex intracranial aneurysm.

Background::Accurate prediction of ischemic stroke is required for deciding anticoagulation use in patients with atrial fibrillation (AF). Even though only 6% to 8% of AF patients die from stroke, about 90% are indicated for anticoagulants according to the current AF management guidelines. Therefore, we aimed to develop an accurate and easy-to-use new risk model for 1-year thromboembolic events (TEs) in Chinese AF patients.Methods::From the prospective China Atrial Fibrillation Registry cohort study, we identified 6601 AF patients who were not treated with anticoagulation or ablation at baseline. We selected the most important variables by the extreme gradient boosting (XGBoost) algorithm and developed a simplified risk model for predicting 1-year TEs. The novel risk score was internally validated using bootstrapping with 1000 replicates and compared with the CHA 2DS 2-VA score (excluding female sex from the CHA 2DS 2-VASc score). Results::Up to the follow-up of 1 year, 163 TEs (ischemic stroke or systemic embolism) occurred. Using the XGBoost algorithm, we selected the three most important variables (congestive heart failure or left ventricular dysfunction, age, and prior stroke, abbreviated as CAS model) to predict 1-year TE risk. We trained a multivariate Cox regression model and assigned point scores proportional to model coefficients. The CAS scheme classified 30.8% (2033/6601) of the patients as low risk for TE (CAS score = 0), with a corresponding 1-year TE risk of 0.81% (95% confidence interval [CI]: 0.41%-1.19%). In our cohort, the C-statistic of CAS model was 0.69 (95% CI: 0.65-0.73), higher than that of CHA 2DS 2-VA score (0.66, 95% CI: 0.62-0.70, Z = 2.01, P = 0.045). The overall net reclassification improvement from CHA 2DS 2-VA categories (low = 0/high &ge;1) to CAS categories (low = 0/high &ge;1) was 12.2% (95% CI: 8.7%-15.7%). Conclusion::In Chinese AF patients, a novel and simple CAS risk model better predicted 1-year TEs than the widely-used CHA 2DS 2- VA risk score and identified a large proportion of patients with low risk of TEs, which could potentially improve anticoagulation decision-making.
