Tracheobronchial adenoid cystic carcinoma (TACC) is a low-grade malignant tumor originating from the airway mucosa. Despite its slow progression,it is characterized by high invasiveness,frequent recurrence,and a strong tendency for metastasis. Preclinical studies have shown that vascular-targeted therapy holds significant potential. However,an effective systemic treatment for TACC has not been established yet. This study explored TACC from the perspective of "Feiji" in traditional Chinese medicine (TCM) as the starting point. It deeply investigated the mechanisms of abnormal collaterals and tumor vascular recruitment and further elaborated on the theoretical connection between abnormal collaterals and tumor vascular recruitment. Firstly,collateral hyperactivity led to disordered and erratic pulmonary collaterals. Their abnormal structures were similar to the disorderly and tortuous nature of tumor (pseudo)angiogenesis. This resulted in imbalances in the functions of circulation,perfusion,and reverse injection of the pulmonary collaterals,and then led to unrestrained collateral dysfunction and the accumulation of pathogenic factors. Secondly,the remodeling of the extracellular matrix (ECM) and epithelial-mesenchymal transition (EMT) in TACC were critical processes in vascular co-option (VCO),representing the micro-level manifestation of the displacement of nutrient and defense. During this process,ECM remodeling made TACC cells more likely to hijack normal blood vessels,creating a complex vascular microenvironment conducive to tumor growth. In terms of treatment,this study proposed a TCM strategy of "regulating collaterals to expel pathogenic factors and nourishing collaterals to strengthen the healthy Qi",and listed potential TCM. These were intended to regulate the Qi and blood in the collaterals,repair the functions of abnormal collaterals,and intervene in the vascular recruitment process of TACC. Future research should focus on improving the TCM clinical syndrome characteristics of TACC. Through modern molecular biology techniques,it is necessary to deeply analyze the micro-level pattern of vascular recruitment in TACC. This would enrich the understanding of the profound connection between abnormal collaterals and tumor vascular recruitment,providing empirical evidence for TCM-targeted therapies for vascular recruitment in TACC.

Objective To investigate the antibacterial effect and its preliminary mechanism of lavender essential oil on multi-drug resistant Acinetobacter baumannii.Methods Micro-dilution method was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)of lavender essential oil against multi-drug resistant Acinetobacter baumannii,and bactericidal kinetic study was employed to determine the onset and maintenance time of lavender essential oil.Meanwhile,the promoting and therapeutic effects of lavender essential oil on wound healing were observed in a mouse model of infection.Subsequently,crystal violet staining was used to determine the inhibition and clearance of multi-drug resistant Acinetobacter baumannii biofilm by lavender essential oil,and laser confocal microscopy was utilized to observe the survival of bacteria in biofilms.NanoDrop instrument was utilized to quantify the leakage of bacterial DNA nucleic acid and protein after intervention with 3 and 6 mg/mL lavender essential oil,and the leakage of bacterial potassium ion was measured by potassium ion test kit.Proteomics technology combined with bio-informatics were applied to explore the action mechanism of lavender essential oil against multi-drug resistant Acinetobacter baumannii.Results The MIC and MBC of lavender essential oil were both 6 mg/mL,which could kill almost all multi-drug resistant Acinetobacter baumannii at the time point of 120 min,and showed an obvious dose-and time-dependent manner.The overall animal model evaluation showed that both 3 and 6 mg/mL lavender essential oil could promote wound healing,and the curative effect was obvious.Further studies confirmed that 3 mg/mL lavender essential oil had a certain biofilm inhibitory effect on multi-drug resistant Acinetobacter baumannii,and 6 mg/mL also had a certain biofilm clearance effect under the same conditions.Meanwhile,when incubated at 37℃ for 1 h,the dose of 3 mg/mL could increase the leakage of DNA nucleic acid and protein,and significantly promote the efflux of potassium ions.Proteomic analysis suggested that the antibacterial effect of lavender essential oil may be related to affecting the oxidorereductase activity and cell metabolic process of multi-drug resistant Acinetobacter baumannii,and interfering with the biosynthesis of cell wall/membrane/envelope and other structures.Conclusion Lavender essential oil at 3 mg/mL can play an antibacterial effect against multi-drug resistant Acinetobacter baumannii,and its mechanism may be related to the destruction of bacterial biofilm and interference with bacterial metabolism.

BackgroundHome-based intervention occupies a prominent place in the treatment of autism spectrum disorder (ASD) in children, whereas previous studies on the effect of home-based early intensive behavioral intervention on verbal ability of children with ASD are somewhat inadequate. ObjectiveTo study the effects of intensive family behavioral of intervention based on Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) on the language ability of children with ASD, so as to provide references for the development of family intervention strategies for children with ASD. MethodsChildren aged 2 to 3 years old who attended the Children's Rehabilitation Department of the Second Affiliated Hospital of Shantou University Medical College from September 2020 to December 2021 and met the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic criteria for ASD were selected as the study objects. A non-randomized concurrent control trial was conducted to compare a study group (n=24) receiving home-based early intensive behavioral intervention using VB-MAPP with a control group (n=14) receiving training from other special institutions or early childhood education institutions. The intervention lasted for 6 months in both groups. Before and after the intervention, the VB-MAPP milestone assessment was performed in the two groups, and the VB-MAPP milestone score, mand, trac and listener responds were selected as the study indicators. Then the intervention effect was compared between two groups, and the multiple linear regression was performed to screen the related influencing factors. ResultsAfter intervention, the total milestone assessment score, mand, tact and listener responds scores of study group were higher than those of control group, with statistical difference (Z=-4.339~-2.195, P<0.05 or 0.01). Multiple linear regression analysis denoted that the average weekly hours of home-based intervention in the first three months had certain effect on listener responds (β=1.029, P<0.05). ConclusionApplication of home-based early intensive behavior intervention using VB-MAPP may contribute to the improvement of verbal abilities such as mand, tact and listener responds in children with ASD.

BACKGROUND:
Despite the progress in perinatal-neonatal medicine, complications of extremely preterm infants continue to constitute the major adverse outcomes in neonatal intensive care unit. Human umbilical cord Wharton’s Jellyderived mesenchymal stem cells (HUMSCs) may offer new hope for the treatment of intractable neonatal disorders. This study will explore the functional differences of HUMSCs between extremely preterm and term infants.
METHODS:
UMSCs from 5 extremely preterm infants(weeks of gestation: 22+5 w,24+4 w,25+3 w,26 w,28 w) and 2 term infants(39 w,39+2 w) were isolated, and mesenchymal markers, pluripotent genes, proliferation rate were analyzed.HUVECs were injured by treated with LPS and repaired by co-cultured with HUMSCs of different gestational ages.
RESULTS:
All HUMSCs showed fibroblast-like adherence to plastic and positively expressed surface marker of CD105,CD73 and CD90, but did not expressed CD45,CD34,CD14,CD79a and HLA-DR; HUMSCs in extremely preterm exhibited significant increase in proliferation as evidenced by CCK8, pluripotency markers OCT-4 tested by RT-PCR also showed increase. Above all, in LPS induced co-cultured inflame systerm, HUMSCs in extremely preterm were more capable to promote wound healing and tube formation in HUVEC cultures, they promoted TGFb1 expression and inhibited IL6 expression.
CONCLUSIONS
Our results suggest that HUMSCs from extremely preterm infants may be more suitable as candidates in cell therapy for the preterm infants.

The view of life in Huang Di Nei Jing discusses the essence of human life by exploring the origin, structure and existence of human life, elucidates the overall quality of human life by observing the state and length of human life, and summarizes the characteristics of human life by analyzing the commonalities and unique characteristics of human life with other lives. On the one hand, this life view respects the objectivity and regularity of life, and enabling people to calmly face death but actively seeking higher possibilities of life, which reflects the reasonable self-awareness of ancient doctors towards human life. On the other hand, it affirms the intrinsic value of life, advocates meeting the subjective value of life and pursuing the external value of life, and expresses the self-pursuit of exploring the existence value of human life, which makes the life view in Huang Di Nei Jing quite humanistic. This humanistic life view has important reference significance for modern medical practice. Reasonable absorbing the humanistic spirit of the life view in Huang Di Nei Jing is conducive to the return of modern medicine to the medical essence of saving the dying and healing the wounded, as well as the establishment of the medical value of people-oriented.

Tumor has become the major reasons cause of death,and its vaccine has become the effective tracts of treatment and prevention by enhancing the immune response of patients.However,most vaccines which are recombination subunit protein antigens are poorly immunogenic and difficult to induce a robust immune response in patients with compromised immune systems,resulting in poor marketing approval.The core component of the vaccine adjuvant can greatly enhance the strength,speed and duration of the immune response,thus becoming the key to the development of an ideal tumor vaccine.Most tumor vaccines are combined with tradition adjuvant such as aluminum,MF59 and AS adjuvant,but their products and patents are monopolized by large foreign companies.We found that natural adjuvants have many unique advantages,such as good biocompatibility and biodegradability,promoting the maturation of dendritic cell and the secretion of immune cytokines,significantly enhancing the tumor vaccine immune response,etc.In this paper,the application and future development of natural polysaccharides,saponins,flavonoid and plant virus-like particles in cancer vaccines were reviewed,which may lay a solid foundation for the development of the original and innovative adjuvants with domestic independent intellectual property rights.

Objective:To investigate the predictive value of mechanism Glasgow age blood pressure score (MGAPS), revised trauma score (RTS) and modified rapid emergency medicine score (mREMS) in predicting the mortality risk of patients with acute traumatic brain injury (TBI) within 24 hours.Methods:A case control study was performed for clinical data of 1 156 patients with acute TBI admitted to Affiliated Hospital of Nantong Hospital from January to December of 2020, including 745 males and 411 females; aged 18-100 years [(59.9±15.1)years]. Glasgow coma score (GCS) was 3-15 points [15(9, 15)points]. The patients were divided into death group ( n=87) and survival group ( n=1 069) according to death or not within 24 hours. Vital signs, general data, MGAPS, RTS and mREMS were documented at emergency visit. Differences in the specific scores and severity levels of the patients using the three scoring systems were compared between the two groups. Receiver operating characteristic (ROC) curve was plotted for the three scoring systems based on the specific scores and severity levels of the patients. While the area under the curve (AUC), sensitivity, specificity, optimal threshold and Youden index were determined to estimate the value of the three scoring systems in predicting death risk in patients with acute TBI within 24 hours. Results:Death group showed significantly decreased scores in MGAPS [17(12, 19)points] and RTS [5.0(4.1, 6.0)points] and significantly increased score in mREMS [9(7, 12)points] when compared with survival group (all P<0.01). The proportion of moderate- and high-risk patients for MGAPS and proportion of high-risk patients for RTS and mREMS in death group were significantly higher than those in survival group (all P<0.01). As indicated by the ROC curve plotted based on the specific scores, mREMS had the maximum AUC (0.88), followed by MGAPS (0.86) and RTS (0.86); the sensitivity of mREMS, MGAPS and RTS was similar (80.5%, 86.2% and 82.8%, respectively), while mREMS showed the highest specificity (83.4%) compared to MGAPS (78.0%) and RTS (82.3%); the optimum threshold of mREMS, MGAPS and RTS, was 6 points, 6.08 points and 20 points; the Youden index of MGAPS, RTS and mREMS was 0.64, 0.64 and 0.65. As indicated by the ROC curve plotted based on the injury severity, MGAPS had the highest AUC (0.84), followed by RTS (0.70) and mREMS (0.59); MGAPS also had the highest sensitivity (92.0%), higher than RTS (47.1%) and RTS (18.4%); when mREMS showed the highest specificity(98.8%) compared to RTS (93.7%) and MGAPS (68.8%); the optimal threshold of MGAPS, RTS and mREMS was 22 points, 4 points and 13 points; the Youden index of MGAPS, RTS and mREMS was 0.61, 0.41 and 0.17. Conclusions:MGAPS, RTS and mREMS can be predictive in assessing the mortality risk of patients with acute TBI within 24 hours. mREMS has the highest prediction value, with an optimal threshold of 6 points when the risk assessment is made in accordance with specific scores of the patients. MGAPS has the highest prediction value when the risk assessment is assessed by the injury severity.
