BACKGROUND: Nasal alar cartilage constitutes the main component of the lower 1/3 of the nose, that is, nose tip, nose wing, and nasal columella, its structure has a decisive role on the nose shape, especially the tip of the nose shape. The intensive study on nasal alar cartilage will help deepen our understandings of nasal alar cartilage morphology, structure and function, and help clinicians to correctly handle the lesions of nose and the lower part and to carry out medical beauty. OBJECTIVE: By observing external nasal anatomy, to clarify the histological role of nasal alar cartilage on nose shape, especially the nasal tip shape.DESIGN, TIME AND SETTING: Experimental observation of repeated measurement was conducted at the Laboratory of Anatomy, Second Military Medical University of Chinese PLA from September 1~(st) to 26~(th), 2006.MATERIALS: Well-preserved bodies of 15 fresh adult, containing 10 males and 5 females were used in this study.METHODS: To fully observe the fine structure of external nose, 30 sides of 15 external noses were dissected, and autopsy started from the medium dorsum of nose, layered anatomy, to observe various layers and the characteristics of the layers with blood vessels, focusing on observation of in vitro pre - and free post-nasal alar cartilage morphology, and measurement and recording were performed.MAIN OUTCOME MEASURES: Big foot medial alar cartilage, lateral feet and the angle of inside and outside legs were measured.RESULTS: Alar cartilage was open for a pair of backward "u"-shaped thin cartilage plate, and lateral nasal cartilage was located below and anteriomedialis the nose, was composed of medial and lateral crus and fornix, with thin body shape, unfixed structure. The shape of fornix was difficult to accurately describe; most presented wavy or folded. Lateral crus presented diamond-shaped or long strip, (16.21±2.71) mm in length, (8.45±1.72) mm in width, (1.09±0.18) mm in thickness. Cephalic rim intersected lower edge of lateral nasal cartilage, and slightly covered the lower edge of the lateral nasal cartilage, so that the two were overlapped, but also only the intersection without overlapping. Lateral crus constituted the base of nasal wings. Narrow medial crus formed nasal tip and the frame of front nasal columeila, showing posteroinferior curve or S shape, (13.06±2.16) mm in length, (3.79±0.58) mm in width, (1.02±0.18) mm in thickness. The left and right medial crus in the middle were connected by connective tissue, and in the same way connected to the anterior margin of the lateral nasal cartilage. Medial and lateral crus in the nasal tip showed an acute angle intersection, its angle (75.25±11.17)°. The medial and lateral crus intersected in the nasal tip and formed the fomix of the greater alar cartilage. The bilateral cornix constituted the frame of the nasal tip. CONCLUSION: Meager nasal alar cartilage is composed of the medial crus, lateral crus and fornix, which determined the nose shape, especially the nasal tip shape. External nose plastic surgery should pay attention to the protection of nasal alar cartilage.

Objective To investigate the roles of TrkA and TrkB in radiation-induced hippocampal neurogenesis impairment.Methods Fifty-six rats were randomized into radiation group and sham control group.Radiation group received whole brain irradiation at a single dose of 10 Gy.The hippocampus were separated from rats in day 1,day 3,day 14 and 1 month after irradiation.Western blot and RT-PCR were applied to detect the protein levels and mRNA levels.Golgi staining was used to observe the dendritic spine of hippocampus.Immunofluorescence was performed to detect neural precursor's proliferation.Results Compared with control group,the numbers of dendritic spine significantly decreased after irradiation and its shape change obviously.Immunofluorescence showed a significant decrease in neural precursor's proliferation comparing with control group (t =6.49,P < 0.05).Protein level of TrkA expression increased (t =2.64,3.06,4.80,2.64,P < 0.05),while the levels of TrkB protein expression decreased significantly (t =4.59,3.06,2.81,2.57,P < 0.05).The mRNA level of TrkA expressions increased (t =4.57,3.06,5.39,5.86,P < 0.05),while the mRNA level of TrkB decreased (t =14.87,11.69,4.98,P < 0.05).Conclusions As a signaling pathways downstream of NGF and BDNF,TrkA and TrkB may play an important role in radiation-induced neurogenesis impairment.

Objective:Based on the data of the baseline survey of hypertension and sodium intake monitoring in Anhui province in 2019, the salt intake in adult residents was estimated.Methods:Multi-stage stratified cluster random sampling was used to select participants aged 18-69 years, questionnaire survey and related measurements were conducted. Salt intake in participants with different characteristics were estimated with complex sample and linearization of Taylor series based on design and the correlation between salt intake and blood pressure, waist circumference and BMI were tested by linear regression.Results:A total of 1 500 participants were included. The overall salt intake was 9.14 g/d, which was 9.84 g/d in men and 8.47 g/d in women ( P<0.05). The differences in salt intake across different subgroups were significant ( P<0.05). Univariate linear regression analysis showed that salt intake was positively correlated with SBP, DBP, waist circumference and BMI ( P<0.05), while multivariate linear regression analysis (adjusted for other factors) only showed a positive correlation between salt intake and BMI ( β=0.053,95% CI: 0.028-0.078, P<0.05). Conclusion:The dietary salt intake in adult residents in Anhui was higher than WHO recommendation, suggesting that public health education need to be taken to reduce salt intake.

After nearly 40 years of development, minimally invasive techniques have been widely applied in curative surgeries for various types of tumors. The safety and efficacy of minimally invasive surgery has being fully validated. With the continuous iteration and updating of medical equipments, the convenience and precision of surgeries have been significantly enhanced, marking the advancement of minimally invasive surgery into a phase of high-level platform. With the rapid development of information technology, we have gradually entered the era of intelligent medicine, where the integration of technologies such as artificial intelligence will inject new vitality into the development of minimally invasive surgery. Combined with the latest research trends, the authors provide an in-depth analysis of how artificial intelligence plays a unique role in key aspects of minimally invasive surgery, including preoperative assessment and planning, intraoperative moni-toring and alerting, and comprehensive postoperative management. Additionally, the authors discuss how to utilize these innovative technologies to further promote reforms in medical education and prospects for the development of telemedicine service. In the era of intelligent medicine, the develop-ment of minimally invasive surgery should adhere to the principle of "bold innovation, cautious practice", guided by the concept of "patient-centeredness". By promoting interdisciplinary collabora-tion between medicine and engineering, accelerating the translation of scientific and technological achievements into clinical practice, we can ensure that minimally invasive surgical techniques better serve the health and well-being of the people.
