Objective:To evaluate the efficacy and safety of induction therapy with first-line chidamide plus chemotherapy and sequential chidamide maintenance therapy for peripheral T-cell lymphoma (PTCL) to provide evidence for clinical medication.Methods:The relevant literature in the databases of Cochrane Library, PubMed, EMbase, Web of Science, Chinese Biomedical Database, China National Knowledge Infrastructure Database, Wanfang, and VIP from December 2014 to November 2023 were retrieved. Meta-analysis and comparison were conducted on the objective response rate (ORR), complete remission (CR) rate, progression-free survival (PFS), and overall survival (OS) of patients receiving induction therapy with first-line chidamide plus chemotherapy and sequential chidamide maintenance therapy (chidamide combined with chemotherapy group) and those receiving chemotherapy alone (control group). A systematic descriptive analysis was performed on the occurrence of adverse events.Results:A total of 5 relevant literature on the induction therapy with first-line chidamide plus CHOP/CHOP-like regimens and sequential chidamide maintenance therapy for PTCL was included, including 350 initial-treated PTCL patients. Among them, there were 176 cases in the chidamide combined with chemotherapy group and 174 cases in the control group. The CR rate of the chidamide combined with chemotherapy group was higher than that of the control group [59.6% (90/151) (95% CI: 51.9%-67.5%) vs. 41.6% (62/149) (95% CI: 27.8%-51.7%)], and the difference was statistically significant ( P < 0.01); the ORR of the chidamide combined with chemotherapy group was 83.4% (126/151) (95% CI: 73.3%-94.1%), while the control group was 69.1% (103/149) (95% CI: 58.4%-79.2%), and the difference was not statistically significant ( P = 0.051). The 2-year PFS rate of the chidamide combined with chemotherapy group was higher than that of the control group [60.2% (106/176) (95% CI: 47.1%-74.6%) vs. 31.6% (55/174) (95% CI: 17.8%-45.7%)], and the difference was statistically significant ( P < 0.01); the 2-year OS rate of the chidamide combined with chemotherapy group was higher than that of the control group [83.2% (114/137) (95% CI: 66.8%-100.0%) vs. 53.4% (93/174) (95% CI: 42.1%-67.9%)], and the difference was statistically significant ( P < 0.01). There was no statistically significant difference between the chidamide combined with chemotherapy group and the control group in the incidence of grade 3-4 neutropenia [60.6% (20/33) and 57.6% (19/33)], anemia [17.9% (20/112) and 16.0% (17/106)] and thrombocytopenia [22.3% (25/112) and 22.6% (24/106)] (all P > 0.05); during the maintenance therapy with chidamide, the incidence of grade 3-4 neutropenia, anemia and thrombocytopenia was 28.1% (9/32), 12.5% (4/32) and 15.6% (5/32), respectively; the hematological adverse events mostly occured within 6 weeks of initial administration and were relieved after symptomatic treatment. Conclusions:Compared with only receiving chemotherapy, the first-line combination therapy with chidamide and CHOP/CHOP-like regimens can improve the CR rate of PTCL patients, and the maintenance therapy with chidamide alone after remission can improve PFS and OS and the hematological adverse reactions are tolerable.

A method for determination and targeted screening of diflorasone components in health products using ultra performance liquid chromatography-quadrupole time of flight mass spectrometry(UPLC-Q-TOF/MS)was established.Four representative diflorasone and esters(diflorasone,diflorasone diacetate,diflorasone-17-propionate,and diflorasone-21-propionate)were selected to optimize the pretreatment conditions,and 10 mL of extraction solvent dosage,15 min of extraction time and 5 g of salting-out agent as the optimal conditions were selected by response surface methodology.The results showed that the four analytes exhibited good linearity within the concentration range of 2.0?100 μg/L with the chromatographic peak area,and the correlation coefficients(R2)were all greater than 0.9990,while the results of recovery and relative standard deviation could satisfy the requirements of determination.The common characteristic ions of diflorasone and esters werem/z121 andm/z335,and their specific structures were obtained by analyzing the cleavage pathway based on the optimized determination conditions.A targeted screening method for other esters of diflorasone based on characteristic ions guidance strategy was established.This method had many advantages such as high efficiency,high sensitivity and good reproducibility,and could be used for targeted screening of diflorasone and esters in health products.The developed characteristic ion guided strategy could be employed to construct mass spectral databases for various glucocorticoids,enabling comprehensive targeted screening across a broad range of compounds.

Objective:To investigate the structural changes in the spinal cord in multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD) and their relationship with clinical disability.Methods:This study was cross-sectional. A retrospective analysis of clinical and imaging data from 124 patients with MS (MS group), 101 patients with aquaporin-4 antibody-positive NMOSD (NMOSD group), and 110 healthy controls (HC group) from seven medical centers were conducted from January 2018 to October 2021. All subjects underwent 3D T 1WI, and the upper cervical spinal cord cross-sectional area (MUCCA) was segmented and measured. All patients completed the expanded disability status scale (EDSS) assessments at baseline and during follow-up, as well as the baseline 25-foot walk test (T25FW) and the nine-hole peg test (NHPT). Patients were classified into EDSS progression and non-progression groups based on follow-up EDSS scores. Comparisons of MUCCA among the three groups were conducted using analysis of covariance, controlling for age and sex as covariates. Pairwise comparisons between groups were performed using the HSD test. Univariate linear regression and logistic models were employed to identify candidate predictors of baseline clinical disability status or EDSS progression in the MS and NMOSD groups. L1 regularized multivariable linear regression analysis was used to determine independent predictors of baseline clinical disability status or EDSS progression. Independent predictors were then combined to establish a logistic regression model, and the model′s performance in predicting EDSS progression was evaluated using receiver operating characteristic analysis and the area under the curve (AUC). Results:A total of 144 patients completed follow-up EDSS assessments, with a follow-up duration of 3.30 (1.10, 6.42) years, including 82 patients in the MS group and 62 patients in the NMOSD group. Controlling for sex and age as covariates, the overall difference in MUCCA among the MS, NMOSD, and HC groups was statistically significant ( P=0.001). The MUCCA in the MS group was lower than that in the HC group, with a significant difference ( t=-2.54, P=0.007); the MUCCA in the NMOSD group was also lower than that in the HC group, with a significant difference ( t=-2.80, P=0.002). However, the difference in MUCCA between the MS and NMOSD groups was not statistically significant ( t=-0.40, P=0.882). In the MS group, MUCCA was an independent predictor of baseline EDSS score (β=-0.03), baseline T25FW score (β=-0.09), and baseline NHPT score (β=-0.30). In the NMOSD group, MUCCA (β=-0.08), age (β=0.06), and baseline EDSS score (β=-0.43) were independent predictors of EDSS progression, and the logistic regression model incorporating these three factors predicted EDSS progression with an AUC of 0.82. Conclusions:Significant spinal cord atrophy occurs in patients with both MS and NMOSD. Atrophy of the upper cervical spinal cord can predict the degree of disability in MS patients and the progression of clinical disability in NMOSD patients.

Osteoporotic fractures(OPF) refer to the fractures caused by minor violence in the state of osteoporosis, seriously threatening the life and health of elderly patients. Drug and surgical therapies have limitations such as single targets, diverse adverse reactions, and poor prognosis. Kidney-tonifying traditional Chinese medicine(TCM) has good potential in the treatment of OPF. TCM can promote the healing of OPF by promoting angiogenesis in the early stage of bone healing, promoting osteogenic differentiation of bone marrow mesenchymal stem cells in the stage of bone repair, maintaining the balance of osteogenic and osteoclastic system in the stage of bone remodeling, and regulating the oxidative stress responses throughout the process of OPF healing. TCM can alleviate the pathological state of osteoporosis and promote fracture healing in OPF patients via multiple pathways and targets, demonstrating the advantages and potential of biphasic regulation.

Objective:To implement an overview of systematic reviews on the effects of brain-computer interface training on upper limb functional rehabilitation in stroke patients.Methods:The systematic review/Meta-analysis of the effect of brain-computer interface training on upper limb functional rehabilitation in stroke patients was electronically retrieved in PubMed, Web of Science, Cochrane Library, Embase, CINAHL, Embase, Joanna Briggs Institute Evidence-Based Health Care Center Database, China National Knowledge Infrastructure, Wanfang Data, VIP and China Biology Medicine disc. The search period was from database establishment to November 2024. Two researchers independently performed literature screening and data extraction and evaluated the quality of methodology, reporting, and evidence.Results:A total of 14 systematic reviews/Meta-analyses were included. The results showed that brain-computer interface training helped to improve upper limb motor function, muscle strength and activities of daily living in stroke patients, but the rehabilitative effect on muscle spasm needed to be further confirmed.Conclusions:Brain-computer interface training helps to improve upper limb motor function, muscle strength and activities of daily living in stroke patients. However, the methodological quality and reporting quality of the current studies are poor, and there is still a need for high-quality studies with rigorous design and standardized process to provide reference for clinical practice.

Hepatocellular carcinoma(HCC),which is essentially primary liver cancer,is closely related to CD8+T cell immune infiltration and immune suppression.We constructed a CD8+T cells related risk score model to pre-dict the prognosis of HCC patients and provided therapeutic guidance based on the risk score.Using integrated bulk RNA sequencing(RNA-seq)and single-cell RNA sequencing(scRNA-seq)datasets,we identified stable CD8+T cell signatures.Based on these signatures,a 3-gene risk score model,comprised of KLRB1,RGS2,and TN-FRSF1B was constructed.The risk score model was well validated through an independent external validation co-hort.We divided patients into high-risk and low-risk groups according to the risk score and compared the differ-ences in immune microenvironment between these two groups.Compared with low-risk patients,high-risk patients have higher M2-type macrophage content(P＜0.0001)and lower CD8+T cells infiltration(P＜0.0001).High-risk patients predict worse response to immunotherapy treatment than low-risk patients(P＜0.01).Drug sensitivity a-nalysis shows that PI3K-β inhibitor AZD6482 and TGFβRII inhibitor SB505124 may be suitable therapies for high-risk patients,while the IGF-1R inhibitor BMS-754807 or the novel pyrimidine-based anti-tumor metabolic drug Gemcitabine could be potential therapeutic choices for low-risk patients.Moreover,expression of these 3-gene mod-el was verified by immunohistochemistry.In summary,the establishment and validation of a CD8+T cell-derived risk model can more accurately predict the prognosis of HCC patients and guide the construction of personalized treatment plans.

Mitochondrial transcription factor B1(TFB1M)is mainly involved in mitochondrial DNA transcription and related to the development of hepatocellular carcinoma and breast cancer.However,its role in colon cancer is unclear.In this study,the expression level of TFB1M in colon cancer and its prognosis were analyzed based on TCGA and other databases and IHC assays.Differentially expressed genes(DEGs)were screened and subjected to the analysis of functional enrichment,mutation analysis,immune cell infiltration,and drug sensitivity analysis.CCK-8 and flow cytometry were used to detect the effects of overexpression of TFB1M on the viability,apoptosis and cell cycle distribution of colon cancer cells.Our results showed that the expression level of TFB1M was significantly up-regulated in colon canc-er,and its expression level was correlated with the N stage and TNM stage(P＜0.05).The prognosis of colorectal cancer patients in the high TFB1M expression group was worse.Functional enrichment results showed that TFB1M was related to leukocyte-mediated immunity,immunoglobulin production and other signaling pathways.Mutation results showed that high-frequency mutated genes,such as ZFHX4,RYR2,PIK3CA and FAT4,had significantly higher mutation frequencies in the TFB1M high-expression group(all P＜0.05).In addition,the expression level of TFB1M was significantly higher in the PIK3CA and FAT4 mutation groups(all P＜0.05).Immune infiltration results showed that the percentage of CD4+memory activated T cells was increased in the TFB1M high expression group,while the percentage of Treg cells was reduced.The drug sensitivity results showed that patients in the TFB1M high expression group might be more sensitive to Tozasertib,cytarabine,vincristine,etc.,while patients in the TFB1M low expression group might be more sensitive to Dasatinib,JQ1,ERK_2440,etc.The results of cellular experiments showed that over-expression of TFB1M enhanced viability,reduced apoptosis and increased the percentage of S-phase and G2/M-phase cells in colon cancer cells.Altogether,the results indicated that TFB1M might play a key role in the growth of colon cancer cells by regulating immune cell infiltration and function.

Objective: To explore the relationship between parenting styles and depressive symptoms in adolescents with nightmare disorder, so as to provide a scientific basis for formulating effective family intervention measures and psychological counseling. Methods: From January 2023 to August 2024, 90 adolescents diagnosed with nightmare disorder and admitted to Hangzhou Seventh Peoples Hospital, along with 176 healthy controls from the urban areas of Hangzhou, were recruited as participants in the study. All participants were assessed using the Nightmare Experience Questionnaire (NEQ), Family Relationship Questionnaire (FRQ), and Plutchik-van Praag Selfreport Depression Scale (PVP). The ttest and Chisquare test were conducted to compare two groups. Pearson correlation and stepwise multiple linear regression were employed to explore the correlations between PVP and NEQ or FRQ. The Process model was used to testing the mediating effects among NEQ/FRQ/PVP. Results: The nightmare disorder group had higher scores in nightmare frequency, the four factors of NEQ (physical effect, negative emotion, meaning interpretation, horrible stimulation), and PVP than the healthy control group (24.86±18.89, 10.12±3.67, 19.01±3.51, 17.02±3.31, 15.14±3.26, 14.02±4.38; 2.34±1.04, 6.49±2.18, 17.63±4.76, 13.91±4.24, 12.40±4.49, 9.39±3.28)(t=15.79, 10.11, 2.43, 6.09, 5.14, 27.46, P<0.05). The nightmare disorder group reported significantly lower scores in FRQ general attachment and maternal encouragement than the healthy control group (7.22±2.81, 16.39±3.28) (t=-5.53, -4.95). In contrast, they exhibited significantly higher scores in maternal abuse, maternal dominance, paternal freedom release, and paternal dominance than the healthy control group (8.23±1.80, 13.11±3.73, 18.36±3.37, 12.04±3.29; 6.07±1.85, 8.48±3.80, 15.15±2.51, 9.47±3.03) (t=6.70, 8.96, 5.90, 7.04, P<0.01). The results of Pearson correlation analysis showed that, in the nightmare disorder group, the PVP score was positively correlated with negative emotion, nightmare frequency, maternal abuse, and maternal dominance score (r=0.14, 0.63, 0.26, 0.51, P<0.05). The results of multiple linear regression analysis showed that when using FRQ score to predict NEQ score, the adjusted R2 in the nightmare disorder group was 0.01-0.59. Mother abuse could prediced physical effect (β=0.33); maternal dominance significantly predicted negative emotion, horrible stimulation, and nightmare frequency (β=0.29, 0.30, 0.79); paternal freedom release could predict negative emotion (β=0.26), paternal dominance predicted both negative emotion and nightmare frequency (β=0.22, 0.45) (P<0.05). Mediation analysis further revealed that, in the nightmare disorder group, PVP scores served as a mediating variable between FRQ and NEQ. Conclusion Abusive, controlling, and neglectful family upbringing styles as well as depression maybe are key factors that may contribute to the development of nightmare disorder among adolescents.
