ABSTRACT
The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Objective:To study the maximum volume of oral cavity (MVOC) of the young adults with normal occlusion and to explore the correlation of MOVC with the height,weight,mouth opening degree and masticatory efficiency.Methods:100 volunteers with normal occlusion(50 for each sex) were enrolled.MVOC was measured by the maximum water capacity method,the height,weight,degree of mouth opening and masticatory efficiency value of the subjects were measured.Results:The average values of MVOC of the male and female were (117.63±15.31) ml and (92.08±14.06) ml respectively(P<0.01).MVOC was positively correlation with the height(r=0.67,P<0.01),weight(r=0.63,P<0.01),degree of mouth opening(r=0.47,P<0.01) and masticatory efficiency(r=0.45,P<0.01).Conclusion:MVOC is moderate-positively correlated and low-positively correlated with mouth opening degree and masticatory efficiency.
ABSTRACT
Long non-coding RNA (lncRNA) is a class of RNA molecules, transcripted by RNA polymeraseⅡ, which consists of more than 200 nucleotides and protein-coding function. Many studies have indicated that lncRNA plays an important role in epigenetics, transcription and post-translational processing. The abnormal expression of lncRNA significantly correlates with occurence,development, and metastasis of renal cell carcinoma (RCC) and prognosis of the patients with RCC. This paper summarizes the advances in the research on lncRNA in RCC to reveal the mechanisms of the disease at the molecular level, in order to provide new methods of prevention, diagnosis, treatment and prognostic assessment of RCC.
