BACKGROUND: In the interim analysis of MONARCH plus, adding abemaciclib to endocrine therapy (ET) improved progression-free survival (PFS) and objective response rate (ORR) in predominantly Chinese postmenopausal women with HR+/HER2- advanced breast cancer (ABC). This study presents the final pre-planned PFS analysis. METHODS: In the phase III MONARCH plus study, postmenopausal women in China, India, Brazil, and South Africa with HR+/HER2- ABC without prior systemic therapy in an advanced setting (cohort A) or progression on prior ET (cohort B) were randomized (2:1) to abemaciclib (150 mg twice daily [BID]) or placebo plus: anastrozole (1.0 mg/day) or letrozole (2.5 mg/day) (cohort A) or fulvestrant (500 mg on days 1 and 15 of cycle 1 and then on day 1 of each subsequent cycle) (cohort B). The primary endpoint was PFS of cohort A. Secondary endpoints included cohort B PFS (key secondary endpoint), ORR, overall survival (OS), safety, and health-related quality of life (HRQoL). RESULTS: In cohort A (abemaciclib: n  = 207; placebo: n  = 99), abemaciclib plus a non-steroidal aromatase inhibitor improved median PFS vs . placebo (28.27 months vs . 14.73 months, hazard ratio [HR]: 0.476; 95% confidence interval [95% CI]: 0.348-0.649). In cohort B (abemaciclib: n  = 104; placebo: n  = 53), abemaciclib plus fulvestrant improved median PFS vs . placebo (11.41 months vs . 5.59 months, HR: 0.480; 95% CI: 0.322-0.715). Abemaciclib numerically improved ORR. Although immature, a trend toward OS benefit with abemaciclib was observed (cohort A: HR: 0.893, 95% CI: 0.553-1.443; cohort B: HR: 0.512, 95% CI: 0.281-0.931). The most frequent grade ≥3 adverse events in the abemaciclib arms were neutropenia, leukopenia, anemia (both cohorts), and lymphocytopenia (cohort B). Abemaciclib did not cause clinically meaningful changes in patient-reported global health, functioning, or most symptoms vs . placebo. CONCLUSIONS: Abemaciclib plus ET led to improvements in PFS and ORR, a manageable safety profile, and sustained HRQoL, providing clinical benefit without a high toxicity burden or reduced quality of life.

Objective: To systematically evaluate the association between maternal adverse childhood experiences (ACEs) and offspring social behavior, so as to provide a theoretical basis for further research on intergenerational social behavioral development. Methods: Relevant research literature about maternal ACEs and the development of children s maladaptive social behaviors were collected, from China National Knowledge Infrastructure (CNKI), VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, Embase and SpringLink databases, covering the period from the inception of each database to May 2025. The Chinese database matched and searched through three groups of keywords: "Pregnant women" "Mothers" and "Women"; "Bad childhood experience" "Bad early experience" and "Bad adolescent experience"; "Children" "Teenagers" "Children s behavior" "Children s development" "Teenagers behavior" "Internalized behavior" and "Externalized behavior". The English database was searched by three groups of keywords: "Female" "Pregnant women" "Mothers"; "Adverse childhood experiences" "Adverse early childhood experiences" "Adverse experiences of adolescent"; "Child behavior" "Child development" "Adolescent behavior" "Internalized behaviors" "Externalized behaviors". The selected literature was evaluated for quality and data extraction, with OR and 95% CI as effect indicators. Stata 16.0 software was used for heterogeneity testing, subgroup analysis, and publication bias analysis. Results: A total of 14 studies involving 64 302 mother-child pairs were included. The Meta analysis results showed a significant correlation between maternal ACEs and both offspring maladaptive internalized behaviors ( OR=1.75, 95%CI=1.42-2.15, P <0.01) and externalized behaviors ( OR=1.82, 95%CI=1.51-2.20, P <0.01). The results of subgroup analyses showed that in different regions[internalized behaviors:domestic, foreign OR (95% CI )=2.03(1.49-2.76), 1.55(1.19-2.03); externalized behaviors: domestic, foreign OR (95% CI )=2.41(1.52-3.82), 1.65(1.36-2.01)], study type[internalized behaviors: cohort study, cross sectional study OR (95% CI )=1.64(1.34-2.00), 1.85(1.30-2.65); externalized behaviors: cohort study, cross sectional study OR (95% CI )=1.76(1.46-2.12), 2.12(1.40-3.20)], sample size [internalized behaviors: ≥4 000, <4 000 pairs OR (95% CI )=1.69(1.13-2.55), 1.77( 1.41 -2.24); externalized behaviors: ≥3 000, <3 000 pairs OR (95% CI )=1.72(1.37-2.17), 2.13(1.44-3.15)], there were significant and positive association between mothers ACEs and children s internalizing and externalizing behaviors (all P <0.05). Conclusion A substantial positive association exists between maternal ACEs and the development of offspring maladaptive internalized and externalized behaviors, but the result needs to be continued to be validated by more research.

In analytical techniques such as ion mobility spectrometry(IMS)and mass spectrometry(MS),the ionization efficiency of target analytes is primarily constrained by the type of ionization source and factors such as the species and number density of the reactant ions.Systematic investigation into the reactivity differences of various reactant ions under varying conditions can not only significantly enhance the detection sensitivity of target compound product ions but also provide a theoretical foundation for establishing efficient detection methods based on ion-molecule reaction mechanisms.In this study,the pressure of a pressure-tunable photoionization tandem ion mobility spectrometry(PI-tandem-IMS)was reduced from ambient pressure(100 kPa)to low pressure(20 kPa)to systematically examine the reactivity differences between two negative reactant ions,CO3-and CO4-,and methyl salicylate(MeSA)under varying pressures.When the pressure decreased,the increased relative signal intensity of CO4-significantly influenced the detection sensitivity of the characteristic product ion[MeSA·O2]-.Based on differences in ion mobility(k0),the delay time for the opening of TPG2 was adjusted to selectively inject CO-3 and CO-4 in the drift region 2.Independent characterization of the reactivity of these reactant ions with MeSA in the reaction region confirmed that CO4-exhibited superior reactivity toward MeSA.The theoretical model revealed an Arrhenius plot for the ion-molecule reaction between CO4-and MeSA,showing a positive correlation between the reaction rate coefficient(k)and temperature,the activation energy Ea was 62.45 kJ/mol.Furthermore,controlling parameters such as pressure or temperature significantly influenced the progression of this ion-molecule reaction,demonstrating the technical advantages of PI-tandem-IMS in mechanistic studies and regulation of ion-molecule reactions.

The resolving power and sensitivity are critical for on-site detection of hazardous chemicals using stand-alone ion mobility spectrometry(IMS).However,improving the sensitivity and resolving power of IMS has long been a prominent research hot spot.In the commonly used IMS based on the Bradbury-Nielsen gate(BNG),the gating voltage difference(GVD)applied between the two sets of grid wires affects the electric field distribution in the ionization region and the drift region.This,in turn,influences the spatial distribution and temporal width of the injected ion swarm,and has an impact on the ion mobility discrimination,sensitivity,and resolving power of the instrument.This study showed that increasing the GVD could induce an ion converging effect,boosting the ion number density in front of the BNG by nearly 300％.To simultaneously utilize temporal compression and ion converging effects,a novel BNG controlling mode was proposed by adding a chopping state to the conventional controlling mode.This chopping state reduced the mobility discrimination effects between ions with mobility differences up to about 0.90 cm2/(V·s)to 1/22 of their original value.When analyzing hazardous chemical mixtures using the novel BNG controlling mode,compared with conventional mode,the signal intensity of low-mobility methyl salicylate ions(MS·O2)-increased by 18-fold while the resolving power maintained around 100,and the detection limit for MS was improved from 3.75 μg/L to 97 ng/L.This novel BNG controlling mode only added a potential wave to the low voltage wires,with no requirement of changing the structure of the drift tube,and was easy to apply to existing commercial instruments.

Objective:To explore the effects of Qingre Qudu Decoction for fumigation combined with three-gap drainage on wound healing and serum inflammatory factors in patients with acute perianal abscess.Methods:Randomized controlled trial was conducted. A total of 117 patients with acute perianal abscess in the hospital were enrolled as the observation objects between August 2022 and May 2024. According to random number table method, they were divided into observation group (59 cases) and control group (58 cases). Both groups received three-gap drainage therapy. On basis of three-gap drainage, control group was given potassium permanganate, while observation group was given Qingre Qudu Decoction for fumigation. All patients were treated for 14 d. The growth of granulation tissue and wound secretions before and after treatment was evaluated. VAS scale was used to evaluate the degree of incision pain, and Wexner score was used to assess incontinence; ELISA was used to detect serum activator A (ACTA), immunoturbidimetry was used to detect serum CRP, and radioimmunoassay was used to detect serum IL-6 levels. The occurrence of complications and abscess recurrence during treatment was recorded, and clinical efficacy was evaluated.Results:The total effective rate of the observation group was 96.61% (57/59), while that of the control group was 82.76% (48/58), with statistical significance ( χ2=6.10, P=0.014). After treatment, scores of granulation tissue growth and wound secretions in observation group, and scores of VAS and Wexner incontinence in observation group were lower than those in the control group ( t=9.66, 5.00, 7.98, 3.65, P<0.001), and wound healing time was shorter than that in control group ( t=8.41, P<0.001). After treatment, levels of serum ACTA, CRP and IL-6 in observation group were lower than those in control group ( t=15.30, 2.08, 19.34, P<0.01 or P<0.05). The incidence of postoperative complications in the observation group was 6.78% (4/59), while in the control group it was 27.59% (16/58), with statistical significance ( χ2=8.93, P=0.003). Conclusion:Qingre Qudu Decoction for fumigation combined with three-gap drainage can relieve postoperative incision pain, inhibit inflammatory response, accelerate the recovery of wound and promote the recovery of anal function and improve clinical efficacy.

Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

Objective To explore the relationship and internal path between activities of daily living(ADL),sleep quality and mental health of community elderly people in Shanghai.Methods A questionnaire survey was conducted among community residents aged 60 years and older seeing doctors in community health care center of five streets in Shanghai during Sept to Dec,2021 using convenience sampling.Activities of Daily Living(ADL),Pittsburgh Sleep Quality Index(PSQI)and 10-item Kessler Psychological Distress Scale(K10)were adopted in the survey.Single factor analysis,correlation analysis and multiple linear regression were used to analyze the data.The effect relationship between the variables was tested using Bootstrap's mediated effects test.Results A total of 1 864 participants were included in the study.The average score was 15.53±4.47 for ADL,5.60±3.71 for PSQI and 15.50±6.28 for K10.The rate of ADL impairment,poor sleep quality,poor and very poor mental health of the elderly were 23.6%,27.3%,11.9%and 4.9%,respectively.ADL and sleep quality were all positively correlated with mental health(r=0.321,P＜0.001;r=0.466,P＜0.001);ADL was positively correlated with sleep quality(r=0.294,P＜0.001).Multiple linear results of factors influencing mental health showed that ADL(β= 0.457,95%CI:0.341-0.573),sleep quality(β =0.667,95%CI:0.598-0.737)and mental health were positively correlated(P＜0.001).Sleep quality partially mediated the relationship between ADL and mental health(95%CI:0.078-0.124)with an effect size of 33.0%.Conclusion Sleep quality is a mediator between ADL and mental health among community elderly people.Improving ADL and sleep quality may improve mental health in the population.

Radiotherapy is the main treatment for patients with head and neck cancer. Radiation-induced oral mucositis (RIOM) is one of the common complications of patients with head and neck cancer during radiotherapy. It is a mucus injury reaction related to dysphagia and oral pain, which will affect the quality of life and prognosis of patients when it becomes severe. Therefore, prevention and treatment of RIOM are of significance for patients. In this article, the pathogenesis, clinical manifestations, treatment and prevention methods of RIOM were summarized, aiming to provide guidance for the treatment of oral mucositis caused by radiotherapy in patients with head and neck cancer.

Objective:To compare the efficacy of maxillary distraction osteogenesis (DO) and Le FortⅠ osteotomy (LFⅠ) in patients with complex cleft lip and palate.Methods:A retrospective study was conducted, clinical data were collected involving patients with complex cleft lip and palate who required combined orthodontic and orthognathic treatment and were treated at the Stomatological Hospital of Chongqing Medical University from January 2015 to December 2022. Patients were divided into three groups based on the surgical method used for the maxilla: total maxillary distraction (TMD, group A), anterior maxillary distraction (AMD, group B), and Le Fort Ⅰ osteotomy (LFⅠ, group C). Cone-beam CT scans and lateral cephalograms were obtained preoperatively and at 3 months postoperatively. Three-dimensional reconstructions were performed using Mimics 21.0 and Dolphin Imaging 11.9 software to evaluate changes in craniofacial morphology and airway. Data analysis was conducted using SPSS 25.0. Intragroup comparisons before and after surgery were performed using the Wilcoxon rank sum test, and intergroup comparisons among the three groups were conducted using the Kruskal-Wallis H test. Results:A total of 15 patients were included, with 5 patients in each group. The cohort comprised 8 males and 7 females, aged between 15 and 21 years. There were no statistically significant differences in the distribution of gender, age, or cleft lip and palate classification among the three groups ( P>0.05). Postoperatively, all three groups showed improvement in maxillary hypoplasia. Compared to preoperative measurements, the angle formed by the points A (subspinale), N (nasion), and B (supramentale) (ANB angle) increased in all three groups (all P<0.05). The vertical distance from point A to the nasion perpendicular (A-Nperp) increased in groups A and B ( P<0.05 for both) but not in group C ( P>0.05). The area of the alveolar gap showed an increasing trend in all three groups ( P>0.05). The mandibular plane angle (FMA) decreased postoperatively in group B but showed an increasing trend in the other two groups, though the differences were not statistically significant ( P>0.05). Postoperative airway volume increased or showed an increasing trend in groups A ( P<0.05) and B ( P>0.05) but decreased in group C ( P>0.05). Intergroup comparisons showed significant differences in the angle formed by the sella (S), nasion (N), and point A (SNA angle) and the vertical distance from the anterior nasal spine to the coronal plane (ANS-CP) ( P<0.05). Group A had significantly larger SNA angles and ANS-CP values than group B, and the ANS-CP value in group A was significantly larger than in group C (all P<0.05). There were no other statistically significant differences among the groups ( P>0.05). Conclusion:For patients with severe maxillary hypoplasia due to complex cleft lip and palate, TMD can correct sagittal discrepancies between the upper and lower jaws, increase upper airway volume, but may potentially enlarge the alveolar gap area and increase vertical height of the maxilla. AMD result in less change in maxillary position compared to TMD and is mainly used for patients with severe maxillary dental crowding, needing increased arch length, having minor sagittal discrepancies, or with preexisting velopharyngeal dysfunction. LFⅠ result in changes in maxillary position similar to AMD but less than TMD, making it suitable for patients with moderate maxillary hypoplasia and mild maxillary dental crowding. The advantage of LFⅠ lies in its precise postoperative occlusal design and accurate three-dimensional movement of the jaw.
