0.05). But when the flexion exceeded 30?, especially when it exceeded 60?, the displacement in pPc increased markedly, much greater than that of an intact knee (P0.05), while a slight over-restriction may be found at some angles. Conclusion Double-band reconstruction could effectively restrict the posterior displacement of the tibia and restore anteroposterior stability to the knee joint within its full range of flexion. aPc reconstruction could also maintain the posterior stability of the knee, while the result of pPc reconstruction is most unsatisfactory.

Objective:To explore the impact of different family management patterns on the family resilience of children with brain tumors.Methods:A total of 210 parents of children with postoperative brain tumors in 2 tertiary Grade A pediatric hospitals were investigated by the general information questionnaire, family management measure (FaMM) and family resilience rating scale.SPSS 24.0 was used for cluster analysis.Results:(1) Among the scores of FaMM, child identity, condition management ability and parental mutuality were significantly positively correlated with family resilience ( r=0.312, r=0.470, r=0.391, all P<0.05), while view of condition impact, condition management difficulty and condition management effort were negatively correlated with family resilience ( r=-0.346, r=-0.177, r=-0.348, all P<0.05). (2) Family management patterns could be divided into four categories: burden managing (22.9%), effective managing (24.8%), poor managing (28.6%) and tacit managing (23.8%). (3) Family resilience scores of the four patterns were (197.21±20.08), (205.92±14.25), (181.47±18.13) and (198.06±17.08), and their differences were statistically significant ( F=19.498, P<0.01). Conclusion:The family resilience level of children with brain tumor is associated with different family management patterns.Therefore, effective strategies according to different family characteristics should be developed to improve family resilience level.

Objective:To evaluate the efficacy and safety of dupilumab in the treatment of adult prurigo nodularis.Methods:A prospective study was conducted on patients with prurigo nodularis who received the treatment with dupilumab in Peking University People′s Hospital from January 2021 to November 2021. Efficacy was assessed using the Investigator′s Global Assessment (IGA) , Numerical Rating Scale (NRS) and Dermatology Life Quality Index (DLQI) at weeks 0, 4 and 16. Wilcoxon signed-rank test and paired t test were used to analyze changes in the above parameters before and after treatment. Results:A total of 17 patients were enrolled in this study, including 12 females and 5 males, aged 48.47 ± 16.26 years. After 16-week treatment with dupilumab, the pruritus NRS score decreased from 8.00 ± 1.50 at baseline to 1.29 ± 0.85 ( t = 6.98, P < 0.001) , the sleeplessness NRS score decreased from 5.18 ± 2.98 at baseline to 0.12 ± 0.49 ( t = 12.55, P < 0.001) , and the DLQI score declined from 13.29 ± 4.03 at baseline to 0.88 ± 0.70 ( t = 16.39, P < 0.001) ; at week 16, the IGA grade of all the 17 patients decreased from 3 - 4 at baseline to 0 - 2, 16 achieved IGA grades 0 - 1, and 12 achieved IGA grade 0. During the treatment, mild conjunctivitis occurred in 2 cases, local injection reaction occurred in 1, and both conditions were improved after short-term symptomatic treatment. Conclusion:Dupilumab is markedly effective and safe in the treatment of adult prurigo nodularis.

Purpose:The study was designed to investigate the feasibility of contrast-enhanced ultrasound in the differentiation of benign and malignant adnexal masses.Materials and Methods:Sixty-nine consecutive patients with adnexal masses received trans vaginal contrast-enhanced ultrasound.The image and perfusion features were assessed.Results:All of 26 malignant tumors showed detectable contrast enhancement,including 24 cases with a quick,heterogeneous or branching pattern.Among 39 benign lesions,24 were cystic with circle or half-circle enhancement,including 5 cases with intra-cystic septum or papillae slightly enhanced.The other 15 cases were solid,8 of them had slightly dotted enhancement.There are significant difference in enhancement patterns between benign and malignant masses ( P < 0.0001).The 4 cases of borderline tumors showed progressive,heterogeneous enhancement.Conclusion:Contrast-enhanced ultrasound is of value in the differentiation of benign and malignant adnexal masses.

OBJECTIVE: In order to raise awareness of CSD and reduce misdiagnosis, we study the manisfection and treatment of CSD with enlarged masses. METHOD: A retrospective study was carried out among the 10 identified patients with CSD on the basis of compatible clinical presentation and confirmatory pathology results for CSD. RESULT: All the 10 patient's first symptoms were masses at some part of the body, more common in the neck. The ratio was 5% at neck, 3% at armpit, 1% at upper, 1% at groin. Two patients had low heat, increased leukocyte and larger masses of more than 2 cm in diameter After surgical resection, and anti-inflammatory treatment. All the patients were cured after surgery and postoperative anti-inflammatory treatment, and there was no recurrence during the 7-year follow-up. CONCLUSION If patients were diagnosed and treated timely, the prognosis will be good. For the cases with extremely enlarged lymphonodus, surgical operation followed by antimicrobial chemotherapy will be a effective treatment.

Disturbance of macrophage-associated lipid metabolism plays a key role in atherosclerosis. Crosstalk between autophagy deficiency and inflammation response in foam cells (FCs) through epigenetic regulation is still poorly understood. Here, we demonstrate that in macrophages, oxidized low-density lipoprotein (ox-LDL) leads to abnormal crosstalk between autophagy and inflammation, thereby causing aberrant lipid metabolism mediated through a dysfunctional transcription factor EB (TFEB)-P300-bromodomain-containing protein 4 (BRD4) axis. ox-LDL led to macrophage autophagy deficiency along with TFEB cytoplasmic accumulation and increased reactive oxygen species generation. This activated P300 promoted BRD4 binding on the promoter regions of inflammatory genes, consequently contributing to inflammation with atherogenesis. Particularly, ox-LDL activated BRD4-dependent super-enhancer associated with liquid-liquid phase separation (LLPS) on the regulatory regions of inflammatory genes. Curcumin (Cur) prominently restored FCs autophagy by promoting TFEB nuclear translocation, optimizing lipid catabolism, and reducing inflammation. The consequences of P300 and BRD4 on super-enhancer formation and inflammatory response in FCs could be prevented by Cur. Furthermore, the anti-atherogenesis effect of Cur was inhibited by macrophage-specific Brd4 overexpression or Tfeb knock-out in Apoe knock-out mice via bone marrow transplantation. The findings identify a novel TFEB-P300-BRD4 axis and establish a new epigenetic paradigm by which Cur regulates autophagy, inhibits inflammation, and decreases lipid content.

Inflammation-driven endothelial dysfunction is the major initiating factor in atherosclerosis, while the underlying mechanism remains elusive. Here, we report that the non-canonical stimulator of interferon genes (STING)-PKR-like ER kinase (PERK) pathway was significantly activated in both human and mice atherosclerotic arteries. Typically, STING activation leads to the activation of interferon regulatory factor 3 (IRF3) and nuclear factor-kappa B (NF-κB)/p65, thereby facilitating IFN signals and inflammation. In contrast, our study reveals the activated non-canonical STING-PERK pathway increases scaffold protein bromodomain protein 4 (BRD4) expression, which encourages the formation of super-enhancers on the proximal promoter regions of the proinflammatory cytokines, thereby enabling the transactivation of these cytokines by integrating activated IRF3 and NF-κB via a condensation process. Endothelium-specific STING and BRD4 deficiency significantly decreased the plaque area and inflammation. Mechanistically, this pathway is triggered by leaked mitochondrial DNA (mtDNA) via mitochondrial permeability transition pore (mPTP), formed by voltage-dependent anion channel 1 (VDAC1) oligomer interaction with oxidized mtDNA upon cholesterol oxidation stimulation. Especially, compared to macrophages, endothelial STING activation plays a more pronounced role in atherosclerosis. We propose a non-canonical STING-PERK pathway-dependent epigenetic paradigm in atherosclerosis that integrates IRF3, NF-κB and BRD4 in inflammatory responses, which provides emerging therapeutic modalities for vascular endothelial dysfunction.
