Objective To establish a quality evaluation method for Abri Mollis Herba based on its morphological characteristics, microscopic features, and the determination of principal component contents. Methods The morphological characteristics of Abri Mollis Herba were identified by morphological authentication methods. Microscopic techniques were employed to observe the microscopic features of both the powdered form and cross-sectional tissue of Abri Mollis Herba. Additionally, a high-performance liquid chromatography （HPLC） method was developed to establish the quantify the main components, abrine and soyasaponin Bb, in Abri Mollis Herba. Results The morphological characteristics of Abri Mollis Herba were defined by numerous long pubescence on both the upper and lower surfaces of the leaflets, with indistinct veins and vein islands. The microscopic features mainly included non-glandular hairs, prismatic crystals, and crystal-sheathed fibers in the powdered form. In the root cross-section, xylem bundles, rays, vessels, and stone cells were visible. The stem cross-section displayed rays, vessels, and a hollow pith, while the leaf cross-section revealed collateral vascular bundles, vessels, and prismatic crystals. Conclusion The quality of Abri Mollis Herba could be effectively evaluated by the combination of morphological identification, microscopic authentication, and the quantification of main components abrine and soyasaponin Bb .

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.

OBJECTIVES: To investigate the targets and mechanisms of 7-hydroxyethyl chrysin (7-HEC) in prevention and treatment of high-altitude cerebral edema (HACE) in rats. METHODS: Fifty-four male Wistar rats were randomly divided into normal control group, HACE model group, and 7-HEC-treated group (18 rats in each group). Except for the normal control group, rats in the two other groups were exposed to a hypobaric hypoxic chamber simulating a 7000 m altitude for 72 h to establish the HACE model. The 7-HEC-treated group was intraperitoneally injected with 7-HEC (150 mg·kg^－¹·d^－¹) for 3 consecutive days before modeling, while the model group received equivalent isotonic sodium chloride solution. Tandem Mass Tag (TMT) proteomics technology was used to detect differentially expressed proteins (DEPs) with screening criteria set at a fold change >1.2 and P<0.05. Western blotting was used to verify the expression levels of target proteins. Gene Ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and protein-protein interaction (PPI) network analysis were performed. RESULTS: Compared with the normal control group, 256 DEPs were identified in the HACE model group. Compared with the HACE model group, 87 DEPs were identified in the 7-HEC-treated group. Among them, 19 DEPs that were dysregulated in the HACE model group were restored after 7-HEC intervention, of which seven (HSPA4, Arhgap20, SERT, HACL1, CCDC43, POLR3A, and PCBD1) were confirmed by Western blotting. GO enrichment analysis of the DEPs between the HACE model and 7-HEC-treated groups revealed their involvement in 13 biological processes, five cellular components, and two molecular functions. KEGG pathway analysis indicated associations with the mRNA surveillance pathway, Th17 cell differentiation, serotonergic synapse, RNA polymerase, protein processing in the endoplasmic reticulum, peroxisome, neuroactive ligand-receptor interaction, folate biosynthesis. PPI network analysis demonstrated that HSPA4, POLR3A, and HACL1, which were validated by Western blotting, interacted with multiple signaling pathways and ranked among the top 20 hub proteins by degree value, suggesting their potential role as core regulatory factors. Arhgap20, SERT and PCBD1 also exhibited interactions with several proteins, suggesting their potential as key regulatory proteins, whereas no interactions for CCDC43 were identified. CONCLUSIONS This study applied TMT proteomics to identify seven potential therapeutic targets of 7-HEC for the prevention and treatment of HACE. These targets may be involved in the pathogenesis of HACE through multiple pathways, including maintaining cellular homeostasis, ameliorating oxidative stress, regulating energy metabolism, and reducing vascular permeability.

Objective To investigate the clinical and imaging features of extralobar pulmonary sequestration(ELS)with torsion.Methods The clinical and imaging data,surgical records and pathological results of four ELS children with torsion were analyzed ret-rospectively.Results All four children presented with abdominal pain,and all CT scans showed soft tissue masses on the medial side of the lower lobe,and there were 2 masses with long fusculine-shaped in the right pleural cavity,2 round masses in the left pleural cavity,all of which were accompanied by pleural effusion and poor ventilation of adjacent lung lobes.There were 1 case without enhance-ment,1 case with mild enhancement,and 2 cases with simple marginal linear enhancement.There were no patients with definitive supplying artery and 3 cases with peripheral post-intercostal dilated veins.Intraoperative ELS combined with torsion was shown,and the nutrient artery were derived from the thoracic aorta.All ELS showed bleeding and necrosis according to the pathological results,and 1 case was complicated with congenital pulmonary airway malformation(type 2).Conclusion ELS combined with torsion is mostly abdominal pain as the first symptom,and there are soft tissue mass adjacent to the lower lobe with pleural effusion on the affected side as the imaging features with no,mild or marginal linear enhancement,with no supplying artery,and with intracostal posterior venous expansion.

Objective To investigate the clinical characteristics and prognosis of acute myeloid leukemia(AML)patients with PTPN11 gene mutation.Methods Total 115 adult AML patients who underwent initial diagnosis,treatment,and second-generation sequencing(NGS)detecting at hospital were recruited in this study.Clinical da-ta included disease characteristics,treatment efficacy,long-term prognosis,immune cell subpopulations,and leu-kemia stem cells were collected to analyze the clinical characteristics and prognosis of AML patients with PTPN11 gene mutation.Results PTPN11 gene mutation rate in newly diagnosed adult AML was 9.57％,and the mutation site mainly occurred in exon 3 region with all mutation type being point mutation.Compared with PTPN11 wild-type group,PTPN11 gene mutation group had a higher early mortality rate(18.18％vs 4.00％,P=0.048),a lower complete response rate(33.33％vs 67.71％,P=0.039),a higher recurrence rate(83.33％vs 42.31％,P=0.043),a shorter median overall survival time(9 months vs 20 months,P=0.026),a lower proportion of ef-fector T cells[(1.39±0.12)％vs(3.56±0.46)％,P=0.038],and a higher proportion of leukemia stem cells[(13.82±3.66)％vs(3.87±1.40)％,P=0.021].Conclusion PTPN11 gene mutation is a poor prognostic marker for AML.Those patients have a high early mortality rate,low complete remission rate,high recurrence rate,short median overall survival time,a low proportion of effector T cells,and a high proportion of leukemia stem cells.

Objective:This study collected a real-world data on survival and efficacy of gemcitabine-containing therapy in advanced breast cancer. Aimed to find the main reasons of affecting the duration of gemcitabine-base therapy in advanced breast cancer patients.Methods:Advanced breast cancer patients who received gemcitabine-base therapy from January 2017 to January 2019 were enrolled(10 hospitals). The clinicopathological data, the number of chemotherapy cycles and the reasons for treatment termination were collected and analyzed. To identify the reasons related with continuous treatment for advanced breast cancer and the factors which affect the survival and efficacy.Results:A total of 224 patients with advanced breast cancer were enrolled in this study, with a median age of 52 years (26-77 years), 55.4%(124/224) was postmenopausal. Luminal type were 83 cases, TNBC were 97 cases, and human epidermal growth factor receptor 2 (HER's-2) overexpression were 44. At the analysis, 224 patients who received the gemcitabine-based regimens were evaluated, included 5 complete reponse (CR), 77 partial response (PR), 112 stable disease (SD) and 27 progressive disease (PD). The objective response rate (ORR) was 36.6%(82/224). Seventy patients had serious adverse diseases, including leukopenia (9), neutrophilia (49), thrombocytopenia (15), and elevated transaminase (2). The median follow-up time was 41 months (26~61 months), and the median PFS was 5.6 months. The reasons of termination treatment were listed: disease progression were 90 patients; personal reasons were 51 patients; adverse drug reactions were 18 patients; completed treatment were 65 patients. It was found that progression-free survival (PFS) was significantly longer in patients receiving >6 cycles than that in patients with ≤6 cycles (8.2 months vs 5.4 months, HR=2.474, 95% CI: 1.730-3.538, P＜0.001). Conclusions:Gemcitabine-based regimen is generally well tolerated in the Chinese population and has relatively ideal clinical efficacy in the real world. The median PFS is significantly prolonged when the number of treatment cycles are appropriately increased.

【Objective】 To analyze the contributing factors of attention deficit hyperactivity disorder (ADHD) in children and the correlation between bone mineral density and physical growth, in order to provide new clues for the prevention and early intervention of ADHD. 【Methods】 A total of 116 children with ADHD were included into the observation group from June 2020 to June 2022, while another 80 healthy children in the same period were included as the control group.Clinical data of the two groups were compared, and the factors influencing ADHD in children were analyzed using multivariate Logistic regression. Children with ADHD were further divided into boys group and girls group based on gender. Bone mineral density (BMD) and physical growth (height and body weight) of the two groups were measured, and the correlation between the two was analyzed. 【Results】 In the observation group, the proportion of boys, maternal bad behaviors during pregnancy, their educational level below high school, critical parenting, and parental stress index were significantly higher compared to the control group (χ²=14.430, 5.689, 5.630, 6.738, t=6.936, P<0.05). Additionally, family environment score was significantly lower than that in the control group (t=6.328, P<0.05). Logistic regression analysis revealed that factors including boys (OR=3.298, 95%CI: 1.759 - 6.184), maternal bad behaviors during pregnancy (OR=2.730, 95%CI: 1.169 - 6.375), maternal education level of senior high school or below (OR=2.032, 95%CI: 1.127 - 3.663), critical parenting (OR=2.349, 95%CI: 1.223 - 4.513), and parental stress index (OR=1.089, 95%CI: 1.055 - 1.124) were positively correlated with ADHD in children (P<0.05), while family environment score was negatively related to ADHD (OR=0.868, 95%CI: 0.820 - 0.919, P<0.05). There were no significant differences in BMD, height and body weight between boys and girls in ADHD group (P>0.05). Pearson correlation analysis indicated a positive correlation of BMD with height and body weight (r=0.409, 0.317, P<0.05). 【Conclusions】 The development of ADHD in children is associated with gender, maternal bad behavior during pregnancy, family parental style and so on. Bone mineral density is closely related to physical growth in children with ADHD, clinical interventions can be implemented to prevent or early intervene ADHD.

【Objective】 To examine the association between psychological behavioral problems and sleep problems in disabled children in Beijing, in order to provide reference for reducing the sleep problems of disabled children. 【Methods】 From September 2017 to February 2018, children with disabilities aged 6 to 17 years were selected by random sampling, and were investigated by a self-designed questionnaire to get their demographic characteristics.Pediatric Symptom Checklist-17 (PSC-17) was used to assess psychological and behavioral problems.The relationship between psychological behavior and sleep problems was analyzed by binary Logistic regression. 【Result】 Totally 650 children with disabilities were included in the study.The detection rates of sleep problems was significantly different in children with different genders, different school styles, different types of disabilities and different grades of disabilities (χ²=3.984, 4.437, 12.925, 18.104, P<0.001). There was statistically significant difference in the detection rate of sleep problems between children with and without psychological and behavioral problems (χ²=30.722, P<0.001).Psychological and behavioral problems were the main risk factors for sleep problems of disabled children (OR=2.540, 95%CI:1.740 - 3.709).The risk of sleep problems in day students with disabilities was 1.577 times as high as that of boarders with disabilities. 【Conclusions】 Psychological and behavioral problems of disabled children are related to sleep problems.Improving psychological and behavioral status can effectively prevent their sleep problems.
