Objective: To systematically review the development and changes in mental health policies within the National Outline for Children s Development in China from 1992 to 2030, providing a reference basis for future formulation of mental health policies among children and adolescent in China. Methods: Based on the four editions of the National Outline for Children s Development in China across different periods from 1992 to 2030, word frequency analysis was used to reveal shifts in policy priorities, and an internationally recognized framework for adolescent health policy analysis was applied to conduct a textual review. Results: Word frequency analysis revealed that the term "psychological" appeared 6 times in the National Outline for Children s Development in China (2001-2010) but increased to 20 times in the National Outline for Children s Development in China (2021-2030) (abbreviated as the National Outline of 2021), while the term "health" rose from 4 times in the National Outline for Children s Development Plan in China in the 1990s to 68 times in the National Outline of 2021. The scope of mental health policy interventions expanded to encompass five key areas:health, safety, education, welfare and legal protection. Textual analysis highlighted that the policies of the National Outline for Children s Development in China were demand driven, prioritized vulnerable groups and continuously broadened their coverage, emphasizing sustainability and appropriateness, and monitoring/evaluation mechanisms. By 2023, 42.3% of primary schools and 64.8% of secondary schools employed full time mental health education teachers. However, the National Outline for Children s Development in China lacked direct evidence of children and adolescents participation in policy formulation, and publicly available mental health data disaggregated by age and gender remained limited. Conclusion Mental health policies of children and adolescents in China have evolved from nonexistence to gradual refinement, yet institutionalized channels for youth involvement in policy development and evaluation remain insufficient, and transparency in age and gender specific mental health data needs improvement.

Objective: To investigate the changes in the levels of interleukin-6 (IL-6) and let-7e in rats induced by coal mine dust, so as to provide the basis for the mechanism of coal worker's pneumoconiosis (CWP). Methods: Sixty-four clean and healthy male Sprague-Dawley rats were randomly divided into the control group, coal dust group, mixed dust group (mixed coal and silica dust) and quartz group. The rats in the control group were exposed to 1 mL physiological saline by non-exposure tracheal perfusion, and the rats in the dust-exposed groups were exposed to 1 mL dust suspension. Rats were sacrificed by anesthesia after 1 month and 6 months, lung tissue was observed using hematoxylin-eosin staining, the pathological change in the lungs was scored using the Szapiel scoring system, the levels of IL-6 in the bronchoalveolar lavage fluid were detected using enzyme-linked immunosorbent assay, and the expression of let-7e was determined by quantitative real-time PCR. Results: A month after exposure, a small amount of coal spots and inflammatory exudation were observed in the lung tissue of the coal dust group and the mixed dust group. The quartz group showed tissue structure destruction and mild fibrosis and thickening of alveolar septum. Six months after exposure, there were more coal spots and slightly thickened alveolar septum in the coal dust group, and hyperplasia of pulmonary interstitial fibers, destruction of alveolar structure and silica nodules were observed in the mixed dust group. In the quartz group, the alveolar structure was obviously destroyed, the interstitial fiber proliferation was significant and silica nodules were seen. Two-factor analysis of variance showed that the interaction between duration of exposure and dust type significantly influenced the pathological score of lung tissue, IL-6 levels, and let-7e expression levels (P<0.05). Under the same dust type, the pathological score of lung tissue and IL-6 levels were higher at 6 months after exposure than at 1 month, while the relative expression of let-7e was lower at 6 months after exposure than at 1 month (all P<0.05). Under the same duration of exposure, the pathological score of lung tissue and IL-6 levels were higher in the dust-exposed groups than in the control group, while the relative expression of let-7e was lower in the dust-exposed groups than in the control group (all P<0.05). Conclusions Coal dust can cause an increase in levels of IL-6 and a decrease in let-7e expression in rats. The type of dust and duration of exposure can interactively affect IL-6 and let-7e.

The patient was a 29-year-old male with a history of hemophilia for more than 10 years. After 6 hours of botulinum toxin injection into the masseter muscle, the redness and swelling of the right face gradually worsened, accompanied by local pain, and restricted mouth opening, etc. The hematoma was absorbed and the swelling subsided significantly after the infusion of coagulation factor Ⅸ. Such cases of large-scale hematomas after botulinum toxin injection in hemophiliacs is rarely reported. This article summarized the diagnosis and treatment process of this case and combines with literature review to provide clinical experience for diagnosis, treatment and prevention of similar complications.

Objective To assess the effect of ultrasonic thyroid artificial intelligence(AI)-assisted diagnostic system(AI-assisted diagnostic system)for diagnosing medullary thyroid carcinoma(MTC)compared with different physicians and taken papillary thyroid carcinoma(PTC)as the controls.Methods Totally 63 MTC,70 PTC and 62 benign thyroid nodules confirmed by pathology were enrolled.AI-assisted diagnostic system was utilized to analyze thyroid nodules and identify the likelihood of malignancy,and the probability value threshold was set at ≥0.40.All thyroid nodules were retrospectively reviewed and categorized by 3 physicians(1 senior physician,1 attending physician and 1 junior physician)according to Chinese thyroid imaging reporting and data system(C-TIRADS).The efficacy of AI-assisted diagnostic system and physicians for diagnosing MTC and PTC were evaluated.Results AI-assisted diagnostic system showed lower sensitivity,specificity,positive predictive value,negative predictive value,accuracy,and area under the curve(AUC)for diagnosing MTC and PTC compared with physicians.Significant differences of AUC were found between senior physician and AI-assisted diagnostic system,as well as between attending physician and AI-assisted diagnostic system for diagnosing MTC and PTC(all P＜0.01),while no significant difference of AUC was between junior physicians and AI-assisted diagnostic system(both P＞0.05).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy and AUC for AI-assisted diagnostic system for diagnosing MTC were all lower than those for diagnosing PTC,but the AUC was not significantly different(P＞0.05).Conclusion Ultrasonic thyroid AI-assisted diagnostic system had relatively high value for diagnosing MTC.

Objective This study aims to observe the clinical effect of bone plate reduction in combination with a re-sorbable plate on large mandibular cysts.Methods Between October 2017 and September 2022,patients with large mandibular cysts in the presence of labial and buccal cortical bone were involved in the study.Intraoral approach was performed for bone plate reduction.Cone beam computed tomography(CBCT)scan was reviewed at 3,6,and 9 months postoperatively to observe postoperative complications.Osteogenic results were assessed at these times to determine the clinical outcomes of this procedure.Results Eleven cases with large mandibular cysts in the presence of cortical bone were evaluated.The average thickness of the cortical bone on the labial and buccal sides was measured to be about(1.98±0.37)mm before surgery,with a mean value of(0.73±0.17)mm at the thinnest part of the plate and up to 0.51 mm at the thinnest part of the plate.The cystic cavities were well re-vealed during the surgeries,which were completed suc-cessfully.Postoperatively,the wounds healed in one stage without infection.The percentages of cyst shrinkage were 20.01%,41.76%,and 73.41%at 3,6,and 9 months after surgery,respectively.Quantitative measurement of bone mineral density in the jaws by CBCT with MIMICS software.The bone mineral densities of the adult bone were 313.78,555.85,and 657.45 HU at the 3,6,and 9 month time intervals,respectively.No significant change in the patient's maxillofacial appearance were observed from the preoperative period as assessed by the patient's and observer's visual analog scale.Conclusion Bone plate reduction is an effective treatment for large mandibular cysts of the oral and maxillofacial re-gion with the presence of cortical bone.

Anti-angiogenic drugs (AADs), which mainly target the vascular endothelial growth factor-A signaling pathway, have become a therapeutic option for cancer patients for two decades. During this period, tremendous clinical experience of anti-angiogenic therapy has been acquired, new AADs have been developed, and the clinical indications for AAD treatment of various cancers have been expanded using monotherapy and combination therapy. However, improvements in the therapeutic outcomes of clinically available AADs and the development of more effective next-generation AADs are still urgently required. This review aims to provide historical and perspective views on tumor angiogenesis to allow readers to gain mechanistic insights and learn new therapeutic development. We revisit the history of concept initiation and AAD discovery, and summarize the up-to-date clinical translation of anti-angiogenic cancer therapy in this field.

Objective To observe the value of right ventricle modified myocardial performance index(RV-Mod-MPI)for evaluating maternal obstetric antiphospholipid syndrome(OAPS)involving fetal right ventricular function.Methods Forty-five pregnant women with maternal OAPS(OAPS group)and 60 healthy pregnant women(control group)were prospectively enrolled.Fetal RV-Mod-MPI was obtained with tricuspid and pulmonary valve flow images by applying pulsed wave Doppler(PW).Late pregnancy conditions and data of newborns after delivery were recorded.The indexes were compared between groups.Receiver operating characteristic curve was drawn,and the area under the curve(AUC)was used to assess the efficacy of fetal RV-Mod-MPI for predicting adverse pregnancy outcomes in OAPS group.Results Compared with those in control group,OAPS group had higher fetal RV-Mod-MPI values,lower newborn birth weight and lower Apgar score at 1 min after birth,as well as higher probability of adverse pregnancy outcomes(all P＜0.05).The AUC of fetal RV-Mod-MPI for predicting adverse pregnancy outcome in OAPS group was 0.726.Conclusion RV-Mod-MPI could be used to evaluate maternal OAPS involving fetal right ventricular function and predict adverse pregnancy outcomes.

This paper interprets the background, content overview and characteristics, clinical practice significance and disciplinary development of Nursing Standards for Clinical Operation Techniques in Critical Care Ultrasound (hereinafter referred to as the Standards) and puts forward reflections on the clinical application of the Standards, aiming to improve the critical care ultrasound techniques of clinical nursing staff, solve nursing challenges and make clinical nursing ultrasound techniques more scientific, standardized and homogenized.

The department of critical care medicine, the clinical base of critical care medicine, is the centralized management unit for the treatment of critical patients. Medicine and nursing are independent disciplines, but both can be fully utilized from different perspectives when dealing with critically ill patients. With the development of critical care medicine understanding and technology, the concept of doctor-nurse integration construction in the department of critical care medicine has emerged. Doctor-nurse integration construction in the department of critical care medicine needs to take severe diseases as the core and academic development as the orientation. Clinical practice should be carried out through medical cooperation, based on critical cognition and unified thinking mode.
