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.

OBJECTIVES: To investigate the clinical features and gene mutation characteristics of combined oxidative phosphorylation deficiency type 7 (COXPD7) caused by mutations in the C12orf65 gene, and to enhance the awareness of this disease. METHODS: A child diagnosed with COXPD7 in the Department of Neurology, Children's Hospital Affiliated to Zhengzhou University in 2021 was included, along with 10 patients reported in the literature. All subjects were analyzed for their genotypes and clinical phenotypes. RESULTS: A total of 11 patients with COXPD7 were included, comprising 1 reported in this study and 10 from the literature. Among the 11 patients, 9 had homozygous mutations in the C12orf65 gene, while 2 had compound heterozygous mutations, which were identified as frameshift or nonsense mutations. The age of onset ranged from 1 day to 2 years, and clinical manifestations included optic nerve atrophy and delays in intellectual and motor development. Eight patients exhibited external ophthalmoplegia, and five patients displayed spastic paralysis. Cranial magnetic resonance imaging revealed optic nerve atrophy in all 11 patients, abnormal brainstem signals in 10 patients, and a lactate peak on brainstem magnetic resonance spectroscopy scans in 3 patients. CONCLUSIONS COXPD7 associated with the C12orf65 gene results from homozygous or compound heterozygous mutations, with primary clinical manifestations of optic nerve atrophy and delays in intellectual and motor development. Some patients may also present with spastic paralysis or external ophthalmoplegia. Cranial imaging reveals symmetrical abnormal signals in bilateral basal ganglia and brainstem, and a lactate peak is observed on brainstem magnetic resonance spectroscopy scans.

OBJECTIVE: To explore the safety and efficacy of high-dose etoposide (VP-16) combined with recombinant human granulocyte colony-stimulating factor (rhG-CSF) as salvage mobilization for peripheral blood stem cells (PBSC) in newly diagnosed multiple myeloma (NDMM) patients. METHODS: From April 2021 to May 2023, eight NDMM patients who had failed to yield sufficient PBSC during initial mobilization with high-dose cyclophosphamide (CTX) combined with rhG-CSF underwent salvage mobilization with 1.2 g/m2 etoposide combined with rhG-CSF 10 μg/(kg·d). The effects and adverse reactions of initial mobilization and salvage mobilization were analyzed. RESULTS: For salvage mobilization and initial mobilization, the numbers of PBSC collections were 16 and 18, respectively. The mean value of total collected CD34⁺ cells were (11.90±5.75)×10⁶/kg and (1.67±0.75)×10⁶/kg (P =0.0010) in salvage mobilization group and initial mobilization group, respectively. The proportion of patients with a total collection of CD34⁺ cell count≥2×10⁶/kg were 100% and 37.5% (P =0.0625), and the proportion of patients with a total collection of CD34⁺ cell count≥5×10⁶/kg were 87.5% and 0% (P =0.0156) in salvage mobilization group and initial mobilization group, respectively. For five patients who underwent high-dose CTX initial mobilization but had a total CD34⁺ cell count < 2×10⁶/kg, successful collection was achieved through salvage mobilization with high-dose VP-16. Salvage mobilization with high-dose VP-16 was scheduled 2-3 weeks after failure of CTX mobilization. Adverse reactions of high-dose VP-16 mobilization did not increase compared to the initial mobilization with high-dose CTX. CONCLUSION As a salvage mobilization regimen, VP-16 1.2 g/m² combined with rhG-CSF is safe and highly effective in NDMM patients who failed to initial mobilization with high-dose CTX combined with rhG-CSF.

OBJECTIVE: This study aimed to explore the interplay between the life-course body mass index (BMI) trajectories and insulin resistance (IR) on incident diabetes. METHODS: This longitudinal cohort included 2,336 participants who had BMI repeatedly measured 3-8 times between 1989 and 2009, as well as glucose and insulin measured in 2009. BMI trajectories were identified using a latent class growth mixed model. The interplay between BMI trajectories and IR on diabetes was explored using the four-way effect decomposition method. Logistic regression and mediation models were used to estimate the interaction and mediation effects, respectively. RESULTS: Three distinct BMI trajectory groups were identified: low-stable ( n = 1,625), medium-increasing ( n = 613), and high-increasing ( n = 98). Both interaction and mediation effects of BMI trajectories and IR on incident diabetes were significant ( P < 0.05). The proportion of incident diabetes was higher in the IR-obesity than in the insulin-sensitivity (IS) obesity group (18.9% vs. 5.8%, P < 0.001). After adjusting for covariates, the odds ratios (95% confidence intervals) of the IR, IS-obesity, and IR-obesity groups vs. the normal group were 3.22 (2.05, 5.16), 2.05 (1.00, 3.97), and 7.98 (5.19, 12.62), respectively. IR mediated 10.7% of the total effect of BMI trajectories on incident diabetes ( P < 0.001). CONCLUSION We found strong interactions and weak mediation effects of IR on the relationship between life-course BMI trajectories and incident diabetes. IS-obesity is associated with a lower risk of incident diabetes than IR-obesity.

Insulin is an important protein hormone that participates in multiple metabolic pathways.Biosynthetic insulin has been widely used in the treatment of type 1 and type 2 diabetes.Currently,the number of reported cases of insulin overdose both at home and abroad is gradually increasing,and insulin homicide is no longer a means of"committing murder without leaving a trace".At present,there are no systematic protocols for the identification of insulin overdose in the field of forensic medi-cine in China.This article introduces the causes,toxicological characteristics,forensic examination,labo-ratory testing methods and indicator reference of insulin overdose.Based on the identification practice and research results and referring to relevant studies on insulin overdose at home and abroad,this pa-per aims to provide recommendations and references for the formulation of forensic identification guide-lines for insulin overdose cases.

Objective To develop an erythrocyte-based delivery system for butyrylcholinesterase(BChE)that is capable of prophylaxis against organophosphorus nerve agents.Methods Recombinant BChE was produced and analyzed for oligomerization via polyacrylamide gel electrophoresis(PAGE)and Western blotting.A modified hypotonic preswelling method was employed to prepare BChE-loaded erythrocytes.The drug loading capacity and encapsulation efficiency were quantified using enzyme-linked immunosorbent assay(ELISA).Catalytic activity was assessed in vitro with an activity detection kit.The system was characterized via scanning electron microscopy(SEM),flow cytometry and a hematology analyzer.Results Recombinant BChE predominantly existed as dimers(85％dimer,15％monomer).The optimized volume ratio of erythrocytes to hypotonic solution was determined as 1:7.Compared with native and empty erythrocytes,BChE-loaded erythrocytes exhibited significantly higher catalytic activity(P＜0.001).The mean corpuscular volume of BChE-loaded erythrocytes increased(P＜0.001),while the mean content of corpuscular hemoglobin and hemoglobin in erythrocytes per 100 mL decreased(P＜0.001).SEM revealed no morphological differences(biconcave disc shape).Hypotonic preswelling moderately increased erythrocyte apoptosis(P＜0.001),but no statistical difference was observed between BChE-loaded and hypotonic-treated erythrocytes(P＞0.05).CD47 expression remained unchanged compared to native erythrocytes(P＞0.05).Conclusion The modified hypotonic preswelling method can generate BChE-loaded erythrocytes that retain the characteristics of native erythrocytes while conferring catalytic activity,offering a novel strategy for clinical intervention against organophosphorus poisoning.

Jinqi Jiangtang Capsule (JQJTC) is clinically used for the prevention and treatment of type 2 diabetes, but the contents of its main chemical components are not yet clear. In this study, an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was established for the determination of 15 components in JQJTC, including new chlorogenic acid, chlorogenic acid, cryptochlorogenic acid, formononetin, ononin, calycosin, calycosin-7-glucoside, astragaloside IV, berberine, epiberberine, berberrubine, coptisine, jatrorrhizine, palmatine and magnoflorine. The method was used to determine the contents of 15 components in the capsule and then to investigate the influence of excipients on the contents of the components in JQJTC. The separation was performed on a ACQUITY UPLC BEH C₁₈ column (100 mm × 2.1 mm, 1.7 μm) with a mobile phase consisting of 0.1% acetic acid and 5 mmol·L^-1 ammonium acetate (A) and acetonitrile (B) with gradient elution at a flow rate of 0.3 mL·min^-1 and a column temperature at 40 ℃. Electron spray ionization was used for mass spectrometry in positive ion mode. The established method meets the requirements of methodology of content determination in Chinese pharmacopoeia. The contents of 15 components in JQJTC varied from high to low. The top 5 contents were berberine, chlorogenic acid, magnoflorine, coptisine, and cryptochlorogenic acid, accounting for 87.31% of the total content. The contents of 10 components, including the alkaloids of coptidis rhizoma (berberine, epiberberine, berberrubine, coptisine, jatrorrhizine, palmatine and magnoflorine) and the organic acids of honeysuckle (new chlorogenic acid, chlorogenic acid, and cryptochlorogenic acid) in the whole formula extract without excipients was significantly lower than that in the capsule. These components accounted for 99.20% of the determined component contents. In this experiment, an accurate, sensitive and efficient UHPLC-MS/MS method for the determination of multi-components in JQJTC was established, which stably and reliably detected the contents of 15 components in the capsule and could provide the basis for more comprehensive quality analysis. It was also found that excipients had an increasing effect on the contents of detected alkaloid and organic acid components, which may be beneficial to the effectiveness of the capsules.

Objective: To explore the prevalence and related factors of overweight, obesity and hypertension comorbidities among children and adolescents in Ningxia, so as to provide a scientific basis for effective early health intervention in children and adolescents. Methods: From September 2021 to June 2022, a total of 4 577 students aged 9-16 were selected from Jinfeng District of Yinchuan City, Shapotou District of Zhongwei City, Yanchi County of Wuzhong City and Pingluo County of Shizuishan City in Ningxia by multi stage cluster random sampling method for questionnaire survey and physical measurement. The influencing factors of overweight, obesity and hypertension comorbidities in children and adolescents were investigated by Chi square test and multivariate unconditioned Logistic regression analysis with weighted complex sampling design. Results: The prevalence of overweight and obesity among primary and secondary school students in Ningxia was 22.87%, the prevalence of hypertension was 1.30%, and the comorbity rate of overweight, obesity and hypertension was 1.07%. Multivariate Logistic regression analysis showed that students aged 13-16 ( OR =15.66,95% CI =3.84-63.96, P <0.05) were more likely to suffer from overweight, obesity and hypertension than students aged 9-12. The students of insufficient sleep duration ( OR =5.47, 95% CI =1.73-17.33, P <0.05) had higher levels of overweight, obesity and hypertension comorbidities than those of adequate sleep duration. Students who had breakfast 1 to 7 times a week ( OR =0.08, 95% CI =0.02-0.37) had lower incidence than those who had breakfast once a week ( P <0.05). Conclusions Age, sleep time and breakfast frequency are all related factors of overweight, obesity and hypertension co morbidity among primary and secondary school students in Ningxia. Close attention should be paid to students aged 9-12 years with insufficient sleep time and fasting in the morning, and carry out scientific education and prevention and control interventions should be carried out.

Objective:To discuss the effect of Aspergillus fumigatus(Af)on DNA damage and interleukin(IL)-33 expression in the human bronchial epithelial cells,and to clarify its related mechanism.Methods:Different concentrations(1,5,and 10 mg·L-1)of Af were used to stimulate the bronchial epithelial BEAS-2B cells to select the appropriate stimulation concentration.When the BEAS-2B cells were treated with N-acetylcysteine(NAC)and Af,the cells were divided into control group,Af group,NAC group,and Af+NAC group.When the BEAS-2B cells were treated with DNA double-strand break repair inhibitor NU7441 and Af,the cells were divided into control group,Af group,NU7441 group,and Af+NU7441 group.The comet assay was used to detect the percentages of comet tail DNA of cells in various groups;immunofluorescence method was used to detect the expression levels of DNA damage-related protein phosphorylated H2AX(yH2AX)in the cells in various groups;2,7-dichlorofluorescein diacetate(DCFH-DA)fluorescence probe was used to detect the levels of reactive oxygen species(ROS)in the cells in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of interleukih-33(IL-33),thymic stromal lymphopoietin(TSLP),and interleukih-25(IL-25)mRNA in the cells in various groups;Western blotting method was used to detect the expression levels of phosphorylated nuclear factor κB(p-NF-κB),phosphorylated ataxia telangiectasia mutated(p-ATM),and γH2AX proteins in the cells in various groups.Results:Compared with control group,the percentage of comet tail DNA and the expression level of γH2AX in the cells in 1 mg·L-1 Af group showed no significant difference(P＞0.05),while the percentage of comet tail DNA and the expression level of γH2AX in the cells in 5 mg·L-1 Af group were significantly increased(P＜0.01);compared with 5 mg·L-1 Af group,the percentage of comet tail DNA and the expression level of γH2AX in the cells in 10 mg·L-1 Af group were significantly increased(P＜0.01).Compared with control group,the ROS levels in the bronchial epithelial cells in 1 mg·L-1 Af group was significantly increased(P＜0.05);compared with 1 mg·L-1 Af group,the ROS level in the cells in 5 mg·L-1 Af group was significantly increased(P＜0.01);compared with 5 mg·L-1 Af group,the ROS level in the cells in 10 mg·L-1 Af group was significantly increased(P＜0.05).After treatment of NAC,compared with Af group,the percentage of comet tail DNA(P＜0.01),the expression level of γH2AX(P＜0.05),and the ROS level(P＜0.01)in the cells in Af+NAC group were significantly decreased;after treatment of NU7441,compared with Af group,the percentage of comet tail DNA and the expression level of yH2AX in the cells in Af+NU7441 group were significantly increased(P＜0.01).The RT-qPCR results showed that after treatment of NAC,compared with control group,the expression level of IL-33 mRNA in the cells in Af group was significantly increased(P＜0.05);compared with Af group,the expression level of IL-33 mRNA in the cells in Af+NAC group was significantly decreased(P＜0.05);after treatment of NU7441,compared with Af group,the expression level of IL-33 mRNA in the cells in Af+NU7441 group was significantly increased(P＜0.05).The Western blotting results showed that after treatment of NAC,compared with control group,the expression levels of p-NF-κB,p-ATM,and γH2AX proteins in the cells in Af group were significantly increased(P＜0.05);after treatment of NU7441,compared with Af group,the expression levels of p-NF-κB,p-ATM,and γH2AX proteins in the cells in Af+NAC group were significantly decreased(P＜0.05);After treat ment of NU7441,compared with Af group,the expression levels of p-NF-κB,p-ATM,and γH2AX proteins in the cells in Af+NU7441 group were significantly increased(P＜0.05).Conclusion:Af promotes the IL-33 expression in the human bronchial epithelial cells by causing DNA damage,and its mechanism may be related to the activation of ATM/NF-κB signaling pathway.

Objective:To observe the proteomic changes in vitreous fluid samples from patients with rhegmatogenous retinal detachment combined with choroidal detachment (RRDCD).Methods:A prospective cross-sectional clinical study. Vitreous fluid samples were collected from 35 patients with RRDCD (RRDCD group) and 40 patients with rhegmatogenous retinal detachment (RRD group) who were diagnosed at Wuhan Aier Eye Hospital between November 2021 and December 2023. Prior to vitrectomy, 0.3-0.5 ml of vitreous fluid was collected from the affected eyes. Differentially expressed proteins were analyzed using Data-Independent Acquisition (DIA). Three of these proteins were randomly selected for validation using enzyme-linked immunosorbent assay (ELISA). Bioinformatics analyses, including gene ontology functional enrichment and kyoto encyclopedia of genes and genomes pathway enrichment, were performed to explore the functions of the differentially expressed proteins.Results:Significant differences were observed between the RRDCD and RRD groups in intraocular pressure ( t=-12.795), the number of retinal tears ( t=4.601), the extent of retinal detachment ( χ2=39.642), axial length ( t=0.840), postoperative proliferative vitreoretinopathy incidence ( χ2=4.730), single-surgery reattachment rate ( χ2=7.717), and best-corrected visual acuity ( t=7.033) at 6 months postoperatively ( P<0.05). A total of 237 differentially expressed proteins were identified between the RRDCD and RRD groups, with 63 upregulated and 174 downregulated. These proteins were involved in pathways such as extracellular matrix-receptor interaction, complement activation, coagulation, and lysosomal pathways. ELISA validation results showed that the expression trends of the three selected proteins in the RRDCD and RRD groups were consistent with the DIA proteomic analysis. Compared to the RRD group, proteins such as fibrin, coagulation factors, cathepsins, and trypsin inhibitors were significantly upregulated in the RRDCD group. Conclusions:The protein expression profile in vitreous fluid samples from RRDCD patients show significant alterations compared to the RRD group. These differential changes suggest that RRDCD is closely associated with complement and coagulation cascade activation, lysosomal pathways, and extracellular matrix remodeling.
