BACKGROUND AND OBJECTIVE: Patients with glioma experience a high symptom burden and have diverse palliative care needs. However, the assessment scales used in palliative care remain non-standardized and highly heterogeneous. To evaluate the application patterns of the current scales used in palliative care for glioma, we aim to identify gaps and assess the need for disease-specific scales in glioma palliative care. METHODS: We conducted a systematic search of five databases including PubMed, Web of Science, Medline, EMBASE, and CINAHL for quantitative studies that reported scale-based assessments in glioma palliative care. We extracted data on scale characteristics, domains, frequency, and psychometric properties. Quality assessments were performed using the Cochrane ROB 2.0 and ROBINS-I tools. RESULTS: Of the 3,405 records initially identified, 72 studies were included. These studies contained 75 distinct scales that were used 193 times. Mood (21.7%), quality of life (24.4%), and supportive care needs (5.2%) assessments were the most frequently assessed items, exceeding half of all scale applications. Among the various assessment dimensions, the Distress Thermometer (DT) was the most frequently used tool for assessing mood, while the Short Form-36 Health Survey Questionnaire (SF-36) was the most frequently used tool for assessing quality of life. The Mini Mental Status Examination (MMSE) was the most common tool for cognitive assessment. Performance status (5.2%) and social support (6.8%) were underrepresented. Only three brain tumor-specific scales were identified. Caregiver-focused scales were limited and predominantly burden-oriented. CONCLUSIONS: There are significant heterogeneity, domain imbalances, and validation gaps in the current use of assessment scales for patients with glioma receiving palliative care. The scale selected for use should be comprehensive and user-friendly.

The ventral anterior (VA) nucleus of the thalamus is a major target of the basal ganglia and is closely associated with the pathogenesis of Parkinson's disease (PD). Notably, the VA receives direct innervation from the hypothalamic histaminergic system. However, its role in PD remains unknown. Here, we assessed the contribution of histamine to VA neuronal activity and PD motor deficits. Functional magnetic resonance imaging showed reduced VA activity in PD patients. Optogenetic activation of VA neurons or histaminergic afferents significantly alleviated motor deficits in 6-OHDA-induced PD rats. Furthermore, histamine excited VA neurons via H1 and H2 receptors and their coupled hyperpolarization-activated cyclic nucleotide-gated channels, inward-rectifier K⁺ channels, or Ca²⁺-activated K⁺ channels. These results demonstrate that histaminergic afferents actively compensate for Parkinsonian motor deficits by biasing VA activity. These findings suggest that targeting VA histamine receptors and downstream ion channels may be a potential therapeutic strategy for PD motor dysfunction.

OBJECTIVE: To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective. METHODS: Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ₊TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction. RESULTS: TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45⁺ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01). CONCLUSIONS TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.

Aim To investigate the changes in the proliferation and apoptosis of Siha cells after knocking down Rho GTPase-activating protein 30(ARHGAP30).Methods After designing specific shARHGAP30 primers and connecting them to the pLKO.1 vector,we transformed them into Escherichia coli competent cells,then co-transfecting them with lentiviral helper plasmids into HEK-293T cells.We collected and filtered cell supernatant to obtain the vi-rus to infect Siha cells.RT-qPCR and Western blot were used to detect knockdown efficiency,as well as changes in the expression of Bax and Bcl-2 after trans-fection.The CCK-8 method was employed to measure the proliferation level of cells after knockdown.Results After successful construction of a lentiviral plasmid with knockdown of the ARHGAP30 gene and establish-ment of stably transfected Siha cells,ARHGAP30 tran-scription and translation(P＜0.01)in Siha cells de-creased,Bax/Bcl-2 significantly decreased(P＜0.01),indicating decreased apoptosis and increased cell proliferation(P＜0.01).Conclusions This study suggests the involvement of ARHGAP30 in the proliferation and apoptosis of Siha cells,and regulating the ARHGAP30 gene may interfere with the occurrence and development of cervical cancer.

Objective To investigate the role and mechanism of epithelial-mesenchymal transition(EMT)in a rat model of bronchopulmonary dysplasia(BPD).Methods The experiment consisted of two parts.(1)Forty-eight preterm rats were randomly divided into a normoxia group and a hyperoxia group,with 24 rats in each group.The hyperoxia group was exposed to 85%oxygen to establish a BPD model,while the normoxia group was kept in room air at normal pressure.Lung tissue samples were collected on days 1,4,7,and 14 of the experiment.(2)Rat type II alveolar epithelial cells(RLE-6TN)were randomly divided into a normoxia group(cultured in air)and a hyperoxia group(cultured in 95%oxygen),and cell samples were collected 12,24,and 48 hours after hyperoxia exposure.Hematoxylin-eosin staining was used to observe alveolarization in preterm rat lungs,and immunofluorescence was used to detect the co-localization of surfactant protein C(SPC)and α-smooth muscle actin(α-SMA)in preterm rat lung tissue and RLE-6TN cells.Quantitative real-time polymerase chain reaction and protein immunoblotting were used to detect the expression levels of EMT-related mRNA and proteins in preterm rat lung tissue and RLE-6TN cells.Results(1)Compared with the normoxia group,the hyperoxia group showed blocked alveolarization and simplified alveolar structure after 7 days of hyperoxia exposure.Co-localization of SPC and α-SMA was observed in lung tissue,with decreased SPC expression and increased α-SMA expression in the hyperoxia group at 7 and 14 days of hyperoxia exposure compared to the normoxia group.In the hyperoxia group,the mRNA and protein levels of TGF-β1,α-SMA,and N-cadherin were increased,while the mRNA and protein levels of SPC and E-cadherin were decreased at 7 and 14 days of hyperoxia exposure compared to the normoxia group(P<0.05).(2)SPC and α-SMA was observed in RLE-6TN cells,with decreased SPC expression and increased α-SMA expression in the hyperoxia group at 24 and 48 hours of hyperoxia exposure compared to the normoxia group.Compared to the normoxia group,the mRNA and protein levels of SPC and E-cadherin in the hyperoxia group were decreased,while the mRNA and protein levels of TGF-β1,α-SMA,and E-cadherin in the hyperoxia group increased at 48 hours of hyperoxia exposure(P<0.05).Conclusions EMT disrupts the tight connections between alveolar epithelial cells in a preterm rat model of BPD,leading to simplified alveolar structure and abnormal development,and is involved in the development of BPD.

Objective To compare the clinical characteristics of diabetes mellitus(DM)patients complicated with pyogenic liver abscess(PLA)and non-DM(NDM)patients complicated with PLA,and provide evidence for clinical diagnosis and treatment.Methods PLA patients who admitted to an affiliated hospital of Anhui Medical University from July 2002 to February 2022 were selected and divided into DM+PLA group and NDM+PLA group according to whether they had DM.General condition,clinical manifestations and signs.complications,biochemical and patho-genic examination results,imaging findings,as well as clinical efficacy and influencing factors of the two groups of patients were analyzed retrospectively.Results 695 PLA patients were included in the analysis,191(27.5％)in the DM+PLA group and 504(72.5％)in the NDM+PLA group.The proportions of males and complication of hypertension in the DM+PLA group were higher than those in the NDM+PLA group,while the proportion of bi-liary diseases and malignant tumors was lower(all P＜0.05).The proportions of patients developing fever,fa-tigue,as well as concurrent anemia and hypoalbuminemia in the DM+PLA group were higher than those in the NDM+PLA group(all P＜0.05).Compared with the NDM+PLA group,the neutrophil count and percentage in the DM+PLA group increased,while total protein,albumin content,and albumin/globulin ratio all decreased(all P＜0.05).The proportions of the detection of Klebsiella pneumoniae and the occurrence of liver right lobe abscess in DM+PLA patients were higher than those of the NDM+PLA group(both P＜0.05).Multivariate logistic re-gression analysis revealed that malignant tumor was a risk factor for affecting the clinical efficacy of PLA patients,invasive treatment was a protect factor for affecting the clinical efficacy of PLA patients,while blood sugar was a risk factor for affecting the clinical efficacy of NDM+PLA patients.Conclusion DM+PLA patients have more se-vere infection symptoms than NDM+PLA patients,and are accompanied by higher proportions of Klebsiella pneu-moniae infection and liver right lobe abscess.It is necessary to strengthen attention to patients with malignant tumor and control blood sugar level,and timely supplement with invasive treatment if necessary.
