Objective To evaluate the efficacy of endoscopic ultrasonography(EUS)guided implantation of 5-FU seeds for progressive gastric cancer.Methods A total of 23 patients with progressive gastric cancer and outflow obstruction were enrolled into the study.During the endoscopy procedure, 45-60 5-FU seeds were implanted into the tumors with guidance of EUS, with an average dose of 100 mg.Volumes of tumor were examined with 3D-EUS before and after the treatment.Results A total of 33 procedures of 5-FU implantation were performed.By measurements of 3D-EUS, the numbers of patients with complete respons, partial response, no change, progressive disease were 1, 15, 6 and 1, respectively.In terms of outflow obstruction improvement, significant effect, obvious effect and average effect were achieved in 6, 7 and 9 patients, respectively, with an overall response rate at 91.4%.Conclusion EUS-guided 5-FU seed implantation in progressive gastric cancer is safe,reliable and effective with few complications.3D-EUS may be a new method to evaluate curative effect.

Objective To investigate the status quo of cancer pain level and cancer pain self-efficacy in the patients with cancer pain and to analyze the influencing factors of cancer pain self-efficacy.Methods The cross sectional investigation was adopted.A total of 200 inpatients with cancer pain in the Affiliated Hospital and Affiliated Hospital of Traditional Chinese Medicine of Southwest Medical University from February to September 2016 were recruited as the respondents by using the convenience sampling method.The questionnaire investigation was performed by adopting the general data questionnaire from,pain degree scale and chro nic pain self-efficacy scale.Results The total score of cancer pain self-efficacy was (45.82±15.47) points,and the score of pain management self-efficacy,symptom coping self-efficacy and somatic function self-efficacy were (10.32 ± 2.93),(17.34 ± 6.22) and (18.16 ± 8.38) points respectively.The five factors of maximal influence degree on cancer pain self-efficacy were the physical exercise situation after illness(| b| =9.96),family economic status(| b| =6.89),maximal pain degree at nearest 24 h(| b | =5.44),average pain degree at nearest 24 h(| b| =4.31) and age(|b| =0.27).Conclusion The cancer pain self-efficacy in the respondents was in the middle-to-low level.The patients with smaller age,good family economic status,usual physical exercise after illness and milder degree in maximal pain within 24 h had higher cancer pain self-efficacy.

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.
