Objective To explore the regulatory role of hederagenin(HG)on glutamate(Glu)-in-duced ferroptosis and corresponding inflammatory responses in mouse hippocampal neuron HT22 cells and investigate its potential mechanisms.Methods HT22 cells were randomly divided into control,Glu and HG groups(n=3).The cells of the control group received no treatment,the cells of the Glu group were treated with 35 mmol/L Glu for 24 h to establish a cellular model of ferroptosis in Alzheimer's disease,and the cells of the HG group were treated with 0.5 μmol/L HG and 35 mmol/L Glu for 24 h simultaneously.FerroOrange fluorescent probe was used to de-tect intracellular Fe2+.The production of reactive oxygen species(ROS),mitochondrial membrane potential,and levels of inflammatory factors TNF-α,IL-1β and IL-6 in the cells were assessed.Finally,the expression of the key regulator of iron death,glutathione peroxidase 4(GPX4)was measured.Results Compared to the control group,the levels of intracellular Fe2+,ROS,TNF-α,IL-1β,and IL-6 were significantly elevated,while the mitochondrial membrane potential was obvi-ously reduced in the Glu group(P<0.05,P<0.01).The HG group had significantly decreased Fe2+,ROS,TNF-α,IL-1β,and IL-6 and enhanced mitochondrial membrane potential than the Glu group(P<0.05,P<0.01).The GPX4 expression was significantly lower in the Glu group than the control group(1.00±0.02 vs 0.46±0.04,P<0.01),and was notably higher in the 0.5 and 1.0 μmol/L HG groups when compared to the Glu group(0.64±0.03 and 0.59±0.05 vs 0.46±0.04,P<0.01).Conclusion HG inhibits ferroptosis by regulating GPX4 expression,and thereby effec-tively alleviates the inflammatory response.

Prolactinomas are the most common subtype of pituitary neuroendocrine tumors(PitNETs),which can be treated with drugs surgery,radiotherapy and so on.For invasive and non-invasive prolactinomas,there is still controversy on the treatment choice of drugs or surgery as the first-line option.In the past decade,with the progress of endoscopic transsphenoidal minimally invasive technology in-depth understanding of PitNETs pseudocapsule,and constructions of Pituitary Tumor Centers of Excellence(PTCOE),the biochemical remission rate by surgical treatment has been significantly improved.For some specific subtypes of prolactinomas,such as microadenomas and enclosed macroadenomas(Knosp grade 0-2),the biochemical remission rate can achieve 90%with the treatment of endoscopic transsphenoidal surgery,which was similar with the drug efficacy.Therefore,the International Pituitary Society made the latest consensus statement on the clinical treatment of prolactinomas suggested that surgery can be performed as first-line option for some selected prolactinomas.This shift of therapeutic strategy was determined in the form of consensus statement,which has a strong clinical guiding significance.

Corticotroph tumors (CTs) are classified into functional CTs and silent CTs (SCTs)according to presence or absence of Cushing's disease manifestations. The pathological manifestations of functional CTs and SCTs are consistent, and both adrenocorticotrophic hormone (ACTH) and T-box transcription factor TBX19 expressions are seen by immunohistochemistry. SCTs have normal peripheral blood ACTH levels, without Cushing's disease manifestations; and SCTs exhibit invasive growth with high recurrence rate. Some studies have suggested that the biochemical silencing mechanism of SCTs involves pro-opiomelanocortin ( POMC, ACTH precursor) gene expression and ACTH secretion. In this paper, the biochemical silencing mechanism of SCTs will be reviewed from aspects of physiological synthesis and regulation of ACTH in normal adenohypophysial cells, and transcription, post-transcriptional regulation, and post-translational regulation of POMC gene, and ACTH abnormal secretion in SCTs.

Objective:To evaluate the effect of obesity on the dose-effect relationship of remimazolam when combined with alfentanil in painless gastroscopy.Methods:American Society of Anesthesiologists physical status Ⅰor Ⅱ patients of both sexes, scheduled for elective painless gastroscopy, aged 18-64 yr, were divided into 2 groups according to the body mass index (BMI): normal (BMI 19-24 kg/m 2) group and obese (BMI≥28 kg/m 2) group.Alfentanil 5 μg/kg combined with remimazolam was given intravenously in all the patients, and the dose of remimazolam was determined by the modified Dixon′s up-and-down method.The initial dose of remimazolam was 0.25 mg/kg, and each time the dose was increased or decreased by 0.05 mg/kg based on the sedative effect.The response was defined as positive when the responses that affected the operation of examination developed during insertion of the gastroscope and within the first 2 min of examination such as swallowing, bucking or body movement.This process was repeated until the seventh intersection occurred.The 50% effective dose (ED 50), 95% effective dose (ED 95), and 95% confidence interval ( CI) of remimazolam were calculated by probit method. Results:There were 26 patients in normal group and 18 patients in obese group.The ED 50 (95% CI) of remimazolam was 0.196 (0.087-0.274) mg/kg, and the ED 95 (95% CI) was 0.322 (0.256-1.397) mg/kg in normal group.The ED 50 (95% CI) of remimazolam was 0.125 (0.102-0.148) mg/kg, and the ED 95 (95% CI) was 0.161 (0.141-0.242) mg/kg in obese group.The ED 50 and ED 95 were significantly lower in obese group than in normal group ( P<0.001). Conclusions:Obesity increases the potency of remimazolam when combined with alfentanil 5 μg/kg in the patients undergoing painless gastroscopy.

Objective:To examine the relationship between conflict management model, perceived social support and psychological distress in psychiatric nurses, and to analyze the mediating effect of conflict management model in the relationship between perceived social support and psychological distress in psychiatric nurses.Methods:In November 2019, a total of 208 nurses in Shandong Mental Health Center were investigated with General Demography Questionnaire, Nurses' Interpersonal Conflict Handling Form Scale, Kessler Psychological Distress Scale and Perceived Social Support Scale.Results:The total score of psychological distress of psychiatric nurses was 22.74±7.71, and the level of psychological distress was negatively correlated with the integrated conflict management model and perceived social support ( r values were -0.329--0.266, P<0.001). The most commonly used conflict management model of psychiatric nurses was "integration". The integrated conflict management model had a partial mediating effect in perceived social support and psychological distress, and the mediating effect accounted for 20.2% of the total effect. Conclusions:Psychological distress of psychiatric nurses is at a moderate to severe level, and integrated conflict management model and perceived social support play an important role in reducing psychological distress of psychiatric nurses. Nursing administrators should carry out relevant intervention studies to improve nurse-patient conflict and guide nurses to adopt integrated conflict management model to reduce psychological distress and improve mental health level.

Objective:To investigate the effects of cattle encephalon glycoside and ignotin(CEGI)on the expression of glial fibrillary acidic protein(GFAP)and neuronal nuclear antigen(NeuN)in the brain of APP/PS1 model mice of Alzheimer's disease.Methods:A total of 36 5-month-old APP/PS1 dual-transgenic model mice were randomly divided into 3 groups: the model group(normal saline 6.6 ml·kg -1·d -1), CEGI group(CEGI 6.6 ml·kg -1·d -1)and donepezil group(donepezil 2 mg·kg -1·d -1), with 12 in each group.Twelve C57BL/6J mice of the same age were used as the normal control group.All mice were given drugs for 6 weeks consecutively.Brain tissue was collected for immunohistochemical staining to detect the expression of amyloid β-protein(Aβ), GFAP and NeuN, which were then analyzed quantitatively. Results:The results of immunohistochemical staining indicated that levels of Aβ and GFAP were higher and levels of NeuN were lower in the model group than in the normal control group(0.147±0.068% vs.0%, 61.750±22.020 vs.26.000±4.598, 0.021±0.002 vs.0.032±0.003, P<0.05). Levels of Aβ and GFAP were lower and levels of NeuN were higher in the CEGI group and the donepezil group than in the model group(0.058±0.055 % vs.0.057±0.045 %, 38.250±5.418 vs.36.130±5.963, 0.029±0.004 vs.0.027±0.003, P<0.05). There was no significant difference in the expression of Aβ, GFAP and NeuN between the CEGI group and the donepezil group( P>0.05). Conclusions:CEGI has multi-target neuroprotective effects via down-regulating the expression of Aβ and GFAP and up-regulating the expression of NeuN.

Objective To study the pathological features of argyrophilic grains in normal aging brain, AD, PD and progressive superior nuclear paralysis patients. Methods Brain tissue samples taken from 5 AD, 3 PD, 2 progressive superior nuclear paralysis patients with complete clinico-pathological data and 4 normal aging brain subjects were stained with HE, Luxol fast blue and Gallyas-Braak silver respectively. Aβ, tau, α-synuclein and P62 antibodies were detected by microscopy with immunohistochemical staining. The pathological features of argyrophilic grains were recorded. Results The Gallyas-Braak silver staining showed argyrophilic grain structure in 4 out of the 14 amygdaloid nucleus tissue samples (2 from AD patients, 1 from progressive superior nuclear paralysis patients and 1 from normal aging brain patients) with a positive rate of 28.6%. The immunohistochemical staining showed positive tau and P62 antibodies. Conclusion Argyrophilic grain lesion is not uncommon in aging-related neurodegenerative diseases such as normal aging brain, AD and progressive superior nuclear paralysis and can thus produce its superposition effect on the clinical symptoms of cognitive impairment in AD and progressive superior nuclear paralysis patients.
