Non-suicidal self-injury behavior and suicidal ideation are important risk factors for suicide attempts in patients with depression.At present,studies have found that there are obvious differences in electroencephalogram(EEG)characteristics between these two.Resting-state EEG analysis reveals that the absolute power of Gamma in specific electrode points is significantly increased in patients with depression accompanied by suicidal ideation.The Beta and Gamma activities of those with non-suicidal self-injury behavior changed.EEG microstate research shows that there are differences in microstates between those with non-suicidal self-injury behavior and those with suicidal ideation.Among them,short segments of microstate sequences have certain potential.In event-related potentials,these two show specific characteristics in components such as P3 wave and N2 wave.The amplitude of N2 wave in patients with depression accompanied by non-suicidal self-injury behavior is lower.Although there are few machine learning-related studies on EEG technology,it has shown certain application prospects.Therefore,this article will summarize the progress of EEG research related to the two,aiming to provide a basis for early prediction of suicide in depression.

Objective:To explore the abnormal brain metabolic pattern and connectivity in temporal lobe epilepsy (TLE) patients.Methods:18F-FDG PET images of 75 patients diagnosed as drug resistant unilateral TLE from January 2014 to December 2016 in Huashan Hospital of Fudan University were collected retrospectively, including 41 (22 males, 19 females, age (28.4±8.7) years) left TLE (LTLE) and 34 (13 males, 21 females, age (28.5±8.8) years) right TLE (RTLE). Forty-four healthy controls (24 males, 20 females, age (31.2±6.2) years) were also enrolled. The cerebral glucose metabolism in TLE patients and the controls were analyzed with statistical parametric mapping (SPM) 12. The brain connectivity based on glucose metabolism were analyzed with bilateral hippocampus and amygdala as seeds. Permutation test with 1 000 permutations was used to analyze data. Results:Compared to control group, in both LTLE and RTLE groups, hypometabolism was found in affected hippocampus, amygdala, insula and temporal gyrus and hypermetabolism was observed in health hippocampus, parahippocampal gyrus, amygdala, lenticular nucleus and thalamus. In addition, hypometabolism was also found in affected superior/middle frontal gyrus and hypermetabolism was also found in bilateral frontal-orbital gyrus, bilateral cerebellum, affected lenticular nucleus and thalamus in LTLE group. In both TLE groups, affected seeds exhibited increased connectivity with affected superior frontal gyrus, lingual gyrus, fusiform gyrus, superior/middle temporal gyrus and temporal pole (all P<0.05); affected seeds exhibited increased connectivity with health superior frontal gyrus ( P=0.005), lingual gyrus ( P=0.018) and transverse temporal gyrus ( P=0.016) in RTLE group in addition. Besides, affected seeds exhibited decreased connectivity with bilateral default mode network (DMN) (all P<0.05), affected caudate nucleus ( P=0.015) and health thalamus ( P=0.008), in a uniform distribution pattern in LTLE group, and with bilateral cerebral cortex in an irregular distribution pattern in RTLE group (all P<0.05). In LTLE group, health seeds exhibited more increased connections with superior ( P=0.005)/middle frontal gyrus ( P=0.042), health hippocampus ( P=0.038), parahippocampal gyrus ( P=0.019), amygdala ( P=0.038), posterior cingulate gyrus ( P=0.004), and bilateral fusiform gyrusand ( P=0.048) compared with RTLE group; while, in RTLE group, health seeds exhibited more decreased connections with health superior ( P=0.047), inferior frontal gyrus ( P<0.001), orbital frontal gyrus ( P<0.001) and rectus gyrus ( P=0.016) compared with LTLE group. Conclusion:Altered brain glucose metabolism and connectivity pattern are found and will elucidate the underlying metabolic pattern of TLE.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective: To observe the alteration of brain glucose metabolic network in patients with somatoform disorders (SFD). Methods: ¹⁸F-fluorodeoxyglucose (FDG) PET images of 18 SFD patients (10 males, 8 females; age: (39.5±12.0) years; illness duration: (3.67±3.20) years) and 21 matched healthy controls (13 males, 8 females; age: (43.9±8.4) years) in Huashan Hospital of Fudan University from October 2011 to December 2012 were enrolled to construct the brain glucose metabolic networks for 2 groups (SFD group, control group) respectively. Then the global network properties (normalized clustering coefficient, normalized shortest path length, small-worldness and global efficiency) and local parameters (clustering coefficient and betweenness centrality of the node) were calculated using the graph theory. Differences between 2 groups were compared by permutation test with 1 000 permutations. The top 20% (18/90) were classified as Hub nodes based on the results of clustering coefficient and betweenness centrality of the node. Results: Small-worldness of SFD patients was similar to that of healthy controls (σ>1). There were decreased tendency in normalized clustering coefficient and global efficiency, and increased tendency in normalized shortest path length in SFD patients, but without significant differences (P>0.05). Compared to healthy controls, the betweenness centrality of left pallidum, left amygdala, left precuneus and right angular gyrus increased (permutation test, P<0.05); the betweenness centrality of left middle temporal gyrus, right superior occipital gyrus decreased (permutation test, P<0.05); the clustering coefficients of bilateral pallidum, bilateral thalamus, and left amygdala decreased (permutation test, P<0.05). Most changed Hub nodes (16/24) belonged to limbic system. Conclusion The changes of topological properties of brain glucose metabolic network in SFD patients including the decreased tendency of small-worldness and global efficiency, as well as the altered Hub nodes, may provide valid imaging evidences for brain dysfunction of somatization symptoms.

Objective:To investigate the correlations between cerebral β-amyloid (Aβ) deposition assessed by 18F-florbetapir (AV45) PET imaging and clinical cognitive symptoms in patients with subtle cognitive decline (SCD) and mild cognitive impairment (MCI). Methods:Data of twenty-four patients (11 males, 13 females, age: (63.2±7.6) years) diagnosed as SCD ( n=15) or MCI ( n=9) from December 2018 to March 2019 in Shanghai Jiao Tong University Affiliated Sixth People′s Hospital were collected prospectively. All patients underwent 18F-AV45 PET imaging, brain MRI T 1 scan and Mini-Mental State Examination (MMSE) within two weeks. 18F-AV45 PET images were analyzed visually (positive, mild positive, negative). After being pretreated according to the MRI, 18F-AV45 PET images were analyzed semi-quantitatively by calculating the standardized uptake value ratio (SUVR) of Aβ deposition in 8 regions of interest (ROIs; frontal lobe, lateral parietal lobe, lateral temporal lobe, medial temporal lobe, occipital lobe, basal ganglia, posterior cingulate and precuneus), with cerebellar gray matter as the reference. Partial correlation coefficients between regional SUVRs and MMSE score were calculated. Results:18F-AV45 PET imaging showed that 16 patients with positive results and 8 patients with mild positive results. MMSE score of 24 patients was 28.2±2.0, and the SUVR was 0.93-1.87. Correlation analysis revealed that Aβ deposition in frontal cortex ( r=-0.432), posterior cingulate lobe ( r=-0.434) and precuneus ( r=-0.418) was negatively correlated with MMSE score (all P<0.05); and no significant correlations between SUVR and MMSE in other brain regions were found ( r values: from -0.412 to -0.110, all P>0.05). Conclusion:18F-AV45 PET imaging can noninvasively detect brain Aβ deposition in patients, and can effectively reflect the clinical cognitive status of patients with SCD and MCI to a certain extent.

Objective The aim of this study was to compare the short-term and long-term prognostic significance of dif-ferent systemic inflammatory scores in patients with gastric cancer:neutrophil lymphocyte ratio(NLR) and platelet lymphocyte ratio ( PLR). Methods The clinical data of 240 patients with gastric cancer who underwent radical surgery were retrospectively analyzed. The relationship between NLR,PLR,glasgow prognostic score( GPS) and clinicopathological characteristics and perioperative compli-cations were compared. Survival analysis was performed using Kaplan-Meier survival analysis. The Log-rank methods were used to test the difference significance,and the multivariate analysis was performed using the Cox regression risk model. Results Patients in the high NLR and PLR groups were older,had a high GPS,deep tumor infiltration,more lymph node metastasis,and a late TNM stage (P<0. 05). The rate of positive margin in the high NLR group was higher(P<0. 05). Patients in the high NLR and PLR groups re-quired significantly higher transfusion rates than those in the low NLR and PLR groups(P<0. 05),and the high NLR group had more postoperative complications(P<0. 05). Univariate analysis showed that age,GPS,tumor location,tumor infiltration depth,lymph node metastasis status,TNM stage,vascular tumor thrombus,nerve infiltration,NLR and PLR were associated with postoperative survival of gastric cancer patients(P<0. 05). The overall survival(OS)in high NLR and high PLR groups was lower than that of low NLR and low PLR groups(P=0. 018 and P<0. 001). Cox regression analysis showed GPS and lymph node metastasis were independent prog-nostic factors of OS(P<0. 001 and P=0. 002). Conclusion Preoperative systemic inflammatory scores NLR and PLR are prognos-tic factors affecting the preoperative clinical outcomes of gastric cancer. It is recommended to be used in combination with other prog-nostic indicators for routine use in the prognosis of patients undergoing radical gastrectomy.

Objective The aim of this study was to investigate the possibility of type 2 vesicular monoamine transporter molecular probe,18 F-FP-(+)-DTBZ, in the monitoring of total islet β cell mass in animal models. Methods Two groups of Wistar rats were included in this study. In the type 1 diabetes group ( n = 6 ) , the streptozotocin ( STZ) was intraperitoneally injected at a dose of 65 mg/kg, and the control group ( n= 6 ) was likewisely injected with an equal volume of saline, Micro- positron emission tomography ( PET )/ computed tomography ( CT) imaging was performed at these rats post injection of18 F-FP-(+)-DTBZ at 0. 5, 1, 4, 6, and 12 months after STZ or saline injection, bodyweight and glucose level were also measured. Results The average standardized uptake values ( SUV) in the pancreas in the type 1 diabetes rats were decreased significantly than that of the control group at 0.5, 1, and, 4 months ( P<0.05) , and there was no significant difference at 6th and 12th months ( P>0.05) post injection of STZ and saline. Fasting blood glucose positively correlated with pancreatic SUV in the two groups at 0.5, 1, and 4 months (P<0.05) post injection of STZ and saline. Conclusion 18F-FP-(+)-DTBZ PET imaging is a promising method for dynamic monitoringβcell mass in type 1 diabetic rats.
