Objective:To evaluate the value of 18F-FDG PET/CT for preoperative localization of epileptogenic foci in refractory epilepsy patients with negative MRI. Methods:Clinical data (550 lobes) of 55 epilepsy patients (38 males, 17 females, age (20.0±8.1) years) with negative MRI who underwent preoperative 18F-FDG PET/CT-MRI between January 2014 and June 2020 at the First Affiliated Hospital of Jinan University were retrospectively analyzed. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of 18F-FDG PET/CT, video electroencephalogram (VEEG), PET/CT+ VEEG and PET/CT-VEEG for localizing epileptogenic foci were calculated using stereoelectroencephalography (SEEG) and the outcomes of at least 1 year of postoperative follow-up as reference standards. χ2 test was used to compare the efficiencies of different examination modalities for unilobar, multilobar and all patients. Results:The correct lateralization rate of epileptogenic foci was 92.6%(25/27) using PET/CT. The sensitivity, specificity, accuracy, PPV and NPV of PET/CT for localization of epileptogenic foci were 65.1%(54/83), 77.9%(364/467), 76.0%(418/550), 34.4%(54/157) and 92.6%(364/393), respectively. The sensitivities of PET/CT-VEEG for localization of epileptogenic foci in all patients and patients with multilobar epilepsy were higher than those of VEEG alone (75.9%(63/83) vs 45.8%(38/83), 68.6%(35/51) vs 31.4%(16/51); χ2 values: 15.80, 14.16, both P<0.001). The specificities of PET/CT+ VEEG for localization of epileptogenic foci in all patients and patients with unilobar epilepsy were higher than those of VEEG alone (97.6%(456/467) vs 94.6%(442/467), 97.9%(282/288) vs 94.1%(271/288); χ2 values: 5.66, 5.48; P values: 0.017, 0.019). The sensitivity of PET/CT-VEEG (PET/CT and VEEG concordance) for localization of epileptogenic foci was higher than that of PET/CT+ VEEG (PET/CT and VEEG discordance) (8/9 vs 28.4%(21/74); χ2=10.40, P=0.001), and its specificity and accuracy were higher than those of PET/CT-VEEG (PET/CT and VEEG discordance) (93.4%(57/61) vs 71.7%(291/406), 92.9%(65/70) vs 72.1%(346/480); χ2 values: 13.23, 13.96; both P<0.001). Conclusions:18F-FDG PET/CT can localize and lateralize epileptogenic foci in patients with negative MRI. The combination of 18F-FDG PET/CT and VEEG improves the sensitivity, specificity, and accuracy for epileptogenic foci detection. 18F-FDG PET/CT is more accurate in detecting epileptogenic foci when it is concordant with VEEG.

Objective:To predict the short-term postoperative recurrence status of patients with refractory temporal lobe epilepsy (TLE) by analyzing preoperative 18F-FDG PET images and patients′ clinical characteristics based on deep residual neural network (ResNet). Methods:Retrospective analysis was conducted on preoperative 18F-FDG PET images and clinical data of 220 patients with refractory TLE (132 males and 88 females, age 23.0(20.0, 30.2) years)) in the First Affiliated Hospital of Jinan University between January 2014 and June 2020. ResNet was used to perform high-throughput feature extraction on preprocessed PET images and clinical features, and to perform a postoperative recurrence prediction task for differentiating patients with TLE. The predictive performance of ResNet model was evaluated by ROC curve analysis, and the AUC was compared with that of classical Cox proportional risk model using Delong test. Results:Based on PET images combined with clinical feature training, AUCs of the ResNet in predicting 12-, 24-, and 36-month postoperative recurrence were 0.895±0.073, 0.861±0.058 and 0.754±0.111, respectively, which were 0.717±0.093, 0.697±0.081 and 0.645±0.087 for Cox proportional hazards model respectively ( z values: -3.00, -2.98, -1.09, P values: 0.011, 0.018, 0.310). The ResNet showed best predictive effect for recurrence events within 12 months after surgery. Conclusion:The ResNet model is expected to be used in clinical practice for postoperative follow-up of patients with TLE, helping for risk stratification and individualized management of postoperative patients.

Objective:To explore the correlation between right atrial function parameters and prognosis in patients with chronic obstructive pulmonary disease(COPD) complicated with pulmonary hypertension.Methods:Eighty-four patients with COPD combined with pulmonary arterial hypertension treated with bosentan combined with milrinone admitted to the First Affiliated Hospital of Xinjiang Medical University during the period of February 2020 to June 2022 were selected as the study subjects, and they were divided into the effective group (63 cases) and the ineffective group (21 cases) according to the treatment effect. Right cardiac function parameters were measured by Philips iE33 color ultrasonography before treatment and 72 h after treatment. Logistic regression was used to analyze the risk factors affecting the treatment outcome of patients, and receiver operating characteristics (ROC) curve was used to analyze the predictive value of right atrial function parameters in the poor prognosis of patients with COPD complicated with pulmonary hypertension.Results:The main pulmonary artery diameter (MPA), right ventricular base transverse diameter (RVd1), right ventricular middle transverse diameter (RVd2), right atrial diameter (RAd) and right ventricular free wall thickness (RVWT) in the effective group were lower than those in the ineffective group: (2.65 ± 0.23) cm vs. (2.90 ± 0.44) cm, (3.46 ± 0.43) cm vs. (3.76 ± 0.72) cm, (3.48 ± 0.42) cm vs. (3.88 ± 0.69) cm, (3.53 ± 0.81) cm vs. (4.03 ± 1.20) cm, (0.63 ± 0.12) cm vs. (0.72 ± 0.21) cm; end-diastolic to end-systolic tricuspid ring displacement (TAPSE) was higher than that in the ineffective group: (2.08 ± 0.32) cm vs. (1.82 ± 0.46) cm, there were statistical differences( P<0.05). Logistic regression analysis showed that RVd1 increased ( OR = 3.717, P<0.05), RVd2 increased ( OR = 2.162, P<0.05), RAd increased ( OR = 2.838, P<0.05) and TAPSE reduction ( OR = 1.704, P<0.05) were risk factors for treatment failure in patients. The results of ROC curve showed that the area under the curve of RVd1, RVd2, RAd, TAPSE in predicting the therapeutic effect of COPD patients with pulmonary hypertension were 0.820, 0.831, 0.872, 0.909, respectively. Conclusions:The independent influencing factors of ineffective patients with COPD combined with pulmonary arterial hypertension treated with bosentan combined with milrinone are the increase of structural parameters of the right heart and the decrease of systolic function parameters. The therapeutic effect of patients can be evaluated clinically according to the level of each parameter.

Background Currently,the diagnosis of depressive disorder relies on symptomatology,which is greatly influenced by subjective factors such as clinicians' experience.Finding more accurate and reliable quantitative diagnostic methods is currently an urgent problem.Objective To explore the value of Fisher discriminant function based on inflammatory cytokines in the diagnosis of depressive disorder,so as to provide references for clinical diagnosis.Methods A total of 136 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)criteria,who underwent inpatient treatment at Hebei Mental Health Center from April 2020 to November 2020,were enrolled as study group.67 healthy participants matched for age and gender,was recruited during the same period.Serum levels of inflammatory cytokine were measured using enzyme-linked immunosorbent assay(ELISA).Fisher discriminant model was employed to establish a discriminant function for inflammatory cytokines exhibiting significant statistical differences between study group and control group,which was then validated.Results The levels of pro-inflammatory cytokines interleukin-1β(IL-1β),interleukin-6(IL-6),interferon-γ(INF-γ)and tumor necrosis factor-α(TNF-α)were higher in the study group compared with control group,with statistically significant differences(U=9.115,5.239,4.431,5.428,P<0.01).Conversely,the levels of anti-inflammatory cytokines interleukin-4(IL-4),interleukin-10(IL-10)and interleukin-13(IL-13)were lower in the study group compared with control group,with statistically significant differences(U=7.398,7.331,7.614,P<0.01).The retrospective test in Fisher discriminant function achieved a correct discrimination rate of 89.66%,and the cross validation achieved a correct discrimination rate of 88.67%.Conclusion The Fisher discriminant function developed in this study may serve as a valuable auxiliary method in the diagnosis of depressive disorder.

Objective To investigate the relationship between preoperative frailty and short-term postoperative complications in elderly breast cancer patients.Methods A convenience sampling method was used to select 231 elderly breast cancer patients who underwent elective surgery in a tertiary care hospital in Beijing from July 2022 to December 2022.General information on elderly patients was collected and the frailty assessment was performed 1 day before surgery,and the occurrence of complications in elderly patients was followed up 30 days after surgery.Results Among the 214 elderly breast cancer patients,37 patients had complications within 30 days postoperatively.Binary logistic regression analysis showed that the risk of complications at 30 days postoperatively was 5.532 times higher in elderly breast cancer patients with preoperative frailty than it in non-frail patients(P＜0.05).Elder breast cancer patients with problems of decreased free movement,increased resistance/loss of endurance,and weight loss had a high risk of postoperative complications.Conclusion Preoperative frailty affects the occurrence of complications in elderly breast cancer patients within 30 days after surgery and suggests that nursing staff should strengthen perioperative health management for elderly breast cancer patients with preoperative frailty and actively prevent the occurrence and development of frailty.

The methods for determining the characteristic chromatogram and index components content of Xuanfu Daizhe Decoction were established to provide a scientific basis for the quality evaluation of substance benchmarks and preparations. Eighteen batches of Xuanfu Daizhe Decoction were prepared with the decoction pieces of different batches and of the same batch were prepared respectively, and the HPLC characteristic chromatograms of these samples were established. The similarities of the chromatographic fingerprints were analyzed. With liquiritin, glycyrrhizic acid, 6-gingerol, ginsenoside Rg_1, and ginsenoside Re as index components, the high performance liquid chromatography was established for content determination with no more than 70%-130% of the mass average as the limit. The results showed that there were 19 characteristic peaks corresponding to the characteristic chromatograms of 18 batches of Xuanfu Daizhe Decoction, including 8 peaks representing liquiritin, 1,5-O-dicaffeoylqunic acid, ginsenoside Rg_1, ginsenoside Re, 1-O-acetyl britannilactone, ginsenoside Rb_1, glycyrrhizic acid, and 6-gingerol, and the fingerprint similarity was greater than 0.97. The contents of liquiritin, glycyrrhizic acid, 6-gingerol, and ginsenosides Rg_1 + Re in the prepared Xuanfu Daizhe Decoction samples were 0.53%-0.86%, 0.61%-1.2%, 0.023%-0.068%, and 0.33%-0.66%, respectively. Except for several batches, most batches of Xuanfu Daizhe Decoction showed stable contents of index components, with no discrete values. The characteristic chromatograms and index components content characterized the information of Inulae Flos, Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, and Zingiberis Rhizoma Recens in Xuanfu Daizhe Decoction. This study provides a scientific basis for the further research on the key chemical properties of substance benchmark and preparations of Xuanfu Daizhe Decoction.
