Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To assess the value of emergency interventional embolization in treating traumatic spleen rupture. Methods A total of 74 patients with traumatic spleen rupture, who were encountered at authors’ hospital during the period from July 2007 to July 2013, were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into embolization group (n = 38) and surgery group (n = 36). Interventional splenic artery embolization was carried out in the patients of the embolization group, and surgical repair was employed in the patients of the surgery group. The operation time, the amount of blood loss during the procedure, the hospitalization days, the preservation rate of the spleen and the occurrence of procedure- related adverse events were recorded, and the results were compared between the two groups. Results No significant difference in the operation time existed between the two groups (P = 0.061). The amount of blood loss during the procedure, the hospitalization days and the occurrence of procedure- related adverse events in the embolization group were significantly lower than those in the surgery group (P < 0.05), while the preservation rate of the spleen of the embolization group was significantly higher than that of the surgery group (P = 0.026). Conclusion Emergency interventional embolization is a safe procedure for the treatment of traumatic spleen rupture, this technique can improve the preservation rate of the spleen when compared with traditional surgical repair treatment.

Human resources development in medical and health is of vital importance to medical and health sector reform and development as well as to medical and health existence and service improvement.Medical and health sector in China has made remarkable progress;however,facing the new requirements from economic and social development and people's new needs for medical health service because of their upaating health concepts and the new promotion by the development of biomedical science and technology,we still have some critical problems in medical and health personnel education.Therefore,the task of conducting careful analysis and exploring the solutions to these problems should be given sufficient attention and completed as soon as possible in the field of medical education.

Medical science is a practical subject.It is the basic characteristic of the medical education to combine the theoretical knowledge with practice,therefore to emphasize and construct and bring into effect effectively the experimental and practical teaching system is very important and significant for the cultivation of medical professionals.

Its'a principal task for the medical universities to foster advanced medical staff for the rural areas.Therefore,its’ a must for all the medical professionals to consider how to foster different kinds of qualified medical staff catering to the various needs from the rural areas.This article is to illustrate how to achieve this goal from the following aspects,such as forming new concept in fostering qualified medical talents,innovating the mode to foster the talents and establishing the base for fostering the medical talents.It will promote the level of the medical staff in the rural areas by means of the establishment of the clinical education base and the radiant influence from the base.
