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 investigate the effect of mechanical stretch on the proliferation and differen-tiation of skeletal satellite cells in mice,and explore its mechanism.Methods The research was divid-ed into two parts.In the first part,all mice were not given osteogenic or adipogenic induction,and randomly divided into a control group,a mechanical stretch(MS)group,a solvent control group[Di-methyl sulfoxide(DMSO)+mechanical stretch],a Notch inhibitor(KY-02111)+mechanical stretch group and a Wnt inhibitor(FLI-06)+mechanical stretch group,with the aim to evaluate cell prolifera-tion and migration,and the effect of mechanical stretch on the Wnt and Notch signaling pathway.In the second part,all mice were randomly divided into 6 groups:a control group,an induced differentia-tion(ID)group,an induced differentiation+mechanical stretch(IDMS)group,an induced differentia-tion+DMSO+mechanical stretch(IDDMS)group,an induced differentiation+Notch inhibitor(KY-02111)+mechanical stretch(IDNMS)group,and an induced differentiation+Wnt inhibitor(FLI-06)+mechanical stretch(IDWMS)group.All groups except the control group were induced differenti-ation using osteoblastic or adipogenic medium,and the IDMS group was applied tensile stress to the cell basement membrane,with the IDDMS and IDNMS groups given DMSO and KY-02111 or FLI-06 with a final concentration of 5 μM into the culture medium,respectively.On the 7th and 14th days af-ter culture,cell proliferation was detected using CCK-8,while on the 14th day after culture,cell mi-gration was observed using the streak method.Alkaline phosphatase and oil red staining were per-formed on all cells.Moreover,the mRNA expression of osteogenic[alkaline phosphatase(ALP)and Runt-related transcription factor(Runx)-2]and adipogenic[fatty acid-binding protein(FABP)4 and li-poprteinlipase(LPL)]differentiation marker genes were quantitatively detected by using the real-time PCR.Meanwhile,while the expression of c-Myc and Cyclin B(CCNB)1 proteins was measured using Western blotting.Results Cell proliferation increased significantly in MS group compared with the con-trol group(P<0.01),while that of IDMMS and IDNMS groups decreased significantly compared with MS group.As to cell migration,MS group was significantly better than the control group(P<0.01),while there was a significant decrease in both IDMMS and IDNMS groups compared with MS group(P<0.01).According to ALP and oil red staining,a significant increase in ALP activity and lipid droplet secretion was observed in skeletal muscle satellite cells of ID groups compared with the control group,with the increase in IDMMS and IDNMS groups significantly greater than MS group.More-over,the results of real-time PCR showed that the expression of ALP and Runx-2mRNA in the osteo-genic induction group and the FABP4 and LPL mRNA in the adipogenic induction group increased sig-nificantly compared with the control group(P<0.05),with a significant decrease in the above measure-ments of IDMS group compared with ID group,but a significant increase in IDMMS and IDNMS groups compared with IDMS group(P<0.01).Meanwhile,according to Western blotting,the expres-sion of c-Myc and CCNB1proteins increased significantly in the skeletal muscle satellite cells of MS group compared with the control group(P<0.01),while that of IDMMS and IDNMS groups decreased significantly compared with MS group(P<0.01).Conclusion Mechanical stretch can promote the prolif-eration and migration of skeletal satellite cells in mice,but inhibit osteogenic and adipogenic differenti-ation.Its mechanism is related to the activation of Wnt and Notch signal pathways.

Objective:To further investigate the safety and efficacy of Belimumab in the treatment of patients with systemic lupus erythematosus (SLE).Methods:All SLE patients treated with Belimumab from May 1, 2020 to February 1, 2022 in Peking Union Medical College Hospital were retrospectively collected and analyzed. The clinical manifestations, the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2000) score, and laboratory test such as levels of anti-dsDNA antibody, the medication before and after Belimumab treatment, adverse events were collected. Normally distributed data were tested using the t-test, otherwise the Wilcoxon paired signed rank test was used. Results:A total of 81 patients were enrolled in this study. The use of belimumab could significantly decrease the SLEDAI-2000 score [10.00(7.75, 12.00) vs. 4.00(3.75, 6.00), Z=-5.38, P<0.001], ESR of SLE patients [19.50(12.75, 32.25) mm/1 h vs. 14.00(7.75, 20.25) mm/1 h, Z=-3.71, P=0.003], anti-dsDNA titer detected by CLIFT [300.00 (117.00, 864.00) vs. 183.00(100.00, 471.00), Z=-4.15, P=0.001], meanwhile, increase the complement C3 [0.78 (0.62, 0.97)g/L vs. 0.69 (0.55, 0.84)g/L, Z=-4.68, P<0.001], and the complement C4 [0.12 (0.08, 0.19)g/L vs. 0.10 (0.05, 0.14)g/L, Z=-4.78, P<0.001]. We also observed that with the use of Belimumab, the dosage of Glucocorticoids decreased significantly, which were [10.00(7.50, 22.50) mg vs. 7.50(5.00, 10.00) mg, Z=-4.90, P<0.001]. In addition, the antibody of IgG, IgA and IgM decreased significantly. Only one patient stopped the administration of Belimumab due to the low level of immunoglobulin. Conclusion:Belimumab can alleviate disease activity of patients with SLE and help in safely tapering the daily dose of glucocorticoid with good safety.

Schizophrenia(SZ)is a serious mental illness,and traditional diagnostic methods are prone to missed and misdiagnosis.Using machine learning(ML)algorithms can extract SZ relative features from functional MRI(fMRI)data,hence being helpful for diagnosing and predicting treatment response of SZ.The research progresses of ML based on fMRI for diagnosis and treatment of SZ were reviewed in this article.

Objective:To explore the effects of early-life maternal deprivation on depressive-like behavior and neurogenesis in the granular layer of hippocampus in adolescent rats (6-7 weeks old).Methods:Neonatal rats were randomly divided into maternal deprivation group and control group, with 3 litters in each group.Rats in the maternal deprivation group were given maternal deprivation from 1 to 14 days after birth and rats in the control group were caged with the mother rats and raised normally.The body weight of rats at 5-6 weeks old was recorded and the increased body weight was calculated.When the rats were 6 weeks old, the sucrose preference test was carried out.Then the rats were killed and immunofluorescence histochemistry was applied to compare the expression of Ki67 and Nestin positive cells in the dentate gyrus of hippocampus.SPSS 22.0 software was used for statistical analysis.The data of the two groups were tested to conform to the normal distribution, and then t-test was carried out. Results:There was significant difference in body weight growth between the two groups at the age of 5-6 weeks.Compared with the control group, rats in the maternal deprivation group had lower body weight growth ((20.57±2.19) g, (30.57±1.25) g, t=3.96, P<0.01)) and lower sucrose preference rate((58.38±53.14)%, (73.88±3.67)%, t=3.21, P<0.01). The results of immunofluorescence showed that the number of Ki67 positive cells in the granular layer of hippocampus in the maternal deprivation group was less than that in the control group ((5.13±0.31), (7.60±0.38), t=5.09, P<0.01), and the number of Nestin immunofluorescence positive cells was more than that in the control group ((16.65±0.79), (7.64±0.70), t=8.51, P<0.01). The Nestin immunofluorescence positive cells in the maternal deprivation group had more protrusions and branches, and the morphology was similar to astrocytes, while the immunofluorescence positive cells in the control group had fewer protrusions, and the cell body was oval. Conclusions:Early-life maternal deprivation leads to depressive-like behavior in adolescent rats, which may be associated with the decrease of neurogenesis and activation of astrocytes in the dentate gyrus of the hippocampus.

Objective:To investigate the relationship between 18F-FDG PET/CT Lugano lymphoma response evaluation criteria and prognosis of patients with diffuse large B-cell lymphoma (DLBCL) at the end of chemotherapy. Methods:A total of 131 patients with DLBCL (63 males, 68 females, age (50.3±17.0) years) who underwent 18F-FDG PET/CT at the end of chemotherapy in the Fourth Hospital of Hebei Medical University from July 2013 to January 2021 were analyzed retrospectively. 18F-FDG PET/CT Lugano lymphoma response evaluation criteria was used to evaluate the response (complete remission (CR), partial remission (PR), stable disease (SD) and progressive disease (PD)). Progression-free survival (PFS) and overall survival (OS) were followed up. Kaplan-Meier survival analysis was used for univariate analysis of clinical parameters and imaging parameters, and Cox proportional hazards regression model was used for multivariate analysis to explore related factors affecting the prognosis of patients with DLBCL. Results:The median follow-up time was 35.47 months for 131 patients with DLBCL. The 5-year PFS rate was 57.3%(75/131), and the 5-year OS rate was 84.0%(110/131). There were 74 cases of CR, 37 cases of PR and 20 cases of PD. Univariate analysis showed that the Lugano lymphoma response evaluation criteria was the influencing factor of PFS and OS (PFS, χ2=72.25, P<0.001; OS, χ2=11.97, P=0.003). Deauville score (DS) of patients with DLBCL was also the influencing factor for PFS ( χ2=62.46, P<0.001) and OS ( χ2=19.95, P<0.001). Ann Arbor stage, Eastern Cooperative Oncology Group physical state (ECOG PS) score and international prognostic index (IPI) were the influencing factors for PFS ( χ2 values: 10.31-15.80, all P<0.05). Ann Arbor stage, ECOG PS score, number of extranodal organ involved, β 2 microglobulin, and IPI were the influencing factors for OS ( χ2 values: 4.97-30.57, all P<0.05). Cox multivariate analysis showed that Lugano lymphoma response evaluation criteria, Ann Arbor stage and ECOG PS score were independent prognostic factors for PFS (relative risk ( RR) and 95% CI: 8.841(4.764-16.405), 1.434(1.111-1.852), 2.125(1.205-3.746), P values: <0.001, 0.006, 0.009) and OS ( RR(95% CI): 3.276(1.304-8.235), 9.728(2.216-42.669), 2.506(1.040-6.039), P values: 0.012, 0.003, 0.041). Conclusion:18F-FDG PET/CT Lugano lymphoma response evaluation criteria can precisely evaluate the prognosis of patients with DLBCL at the end of chemotherapy.

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.

Primary biliary cholangitis is a chronic autoimmune cholestatic disease with a progressive course. This disease is not rare in China, but standardized diagnosis and treatment for primary biliary cholangitis are insufficient. Based on the evidence and guidelines from China and other countries, Rheumatology Branch of Chinese Medical Association developed the recommendations of diagnosis and treatment for primary biliary cholangitis in China. The aim is to help clinicians recognize clinical characters, therapeutic selection and prognosis judgement of primary biliary cholangitis, which will contribute to make diagnosis in time, to select treatment properly and to manage follow-up scientifically.

Objective:To discuss the clinical features and treatment of 19 patients with granulomatosis with polyangiitis (GPA) complicated with hypertrophic cranial pachymeningitis (HCP).Methods:The clinical features of 19 patients diagnosed with GPA complicated with HCP in Peking Union Medical College Hospital were retrospectively analyzed.Results:Among the 315 patients with GPA, 19 (12 males, 7 females, with) were diagnosed with HCP at Peking Union Medical College Hospital. The median age was 57 (19-64) years. In the neurological manifestations per se, all patients had headache, 16 patients had cerebral involvement, which included 8 cases at the frontal area, 8 cases at the temporal area, 8 cases at the skull base area (4 cases with parasellar involvements including 3 cases with cavernous sinus involvement and 2 cases with orbital involvement), 6 cases of tentorium involvement, 2 cases of cerebral palsy, 1 case of calvarium, 1 case of occipital, and 1 case with combined spinal pachymeningitis, respectively. In systemic manifestations, 10 patients had fever, 8 patients had weight lose, 4 patients had lung involvement, 3 patients had kidney involvement, 16 patients had nasosinusitis, 10 patients had tympanitis, and 16 patients had localized GPA. The laboratory tests showed that 15 patients had positive anti-neutrophil cytoplasmic antibodies (ANCA), including 8 cases with positive proteinase 3 (PR3)-ANCA and 6 cases with positive myeloperoxidase (MPO)-ANCA. Sixteen patients had lumbar puncture examination, 9 cases had elevated cerebrospinal pressure, 10 cases had elevated level of protein in cerebrospinal fluid. Nineteen patients were treated with glucocorticoids (12 patients accepted pulse therapy) and immunosuppressive agents. Twelve patients were treated with intrathecal injections of dexamethasone combined with or without Methotrexate (MTX). All 19 patients were improved.Conclusion:HCP, as a rare but serious manifestation of GPA, is not rare in active cases and should be intensively treated.
