Objective To explore the developmental potential of day 3(D3) different quality embryos cultured to blastocyst in vitro fertilization treatment, and to provide laboratory basis for blastocyst culture. Methods A total of 5 510 embryos with blastocyst culture remained after D3 transplantation or freezing from April 2015 to April 2019 were analyzed retrospectively. They were divided into groups according to embryo quality, blastomere number, blastomere homogeneity and fragment rate in D3. And the blastocyst formation rate, high quality blastocyst formation rate and available blastocyst formation rate were compared between the groups.The correlation within each factor and available blastocyst formation was analyzed. Results The blastocyst formation rate, high quality blastocyst formation rate and available blastocyst formation rate of D3 high quality embryo group were higher than those of non-high quality embryo group (P<0.05); compared with 7- 9 cell group, 4- 6 cell group and<4 cell group were lower (P<0.05), but there was no significant difference in CP group or >9 cell group. Compared with the normal size of the blastomere (-), the difference in the size of the blastomere (+) group and the (++/+++) group decreased (P<0.05); compared with the fragment ≤ 10%, the difference in the size of the blastomere between the 10%~25% group and the fragment>25% group decreased (P<0.05). The results of logistic analysis suggested that the embryo quality, blastomere number, homogeneity and fragment rate of D3 were correlated with available blastocyst formation (P<0.05). Conclusion D3 embryo quality, blastomere number, homogeneity and embryo fragment may affect the formation and quality of blastocyst, especially the embryo quality and blastomere number.

目的 分析晚期三阴性乳腺癌(TNBC)的危险因素并建立有效的预后列线图。方法 通过检索美国SEER(surveillance, epidemiology, and end results)数据库筛选晚期TNBC患者,采用单因素和多因素分析来确定晚期TNBC的独立预后因素,并以此构建了列线图,通过校准曲线检验和C指数(C-index)评估已建立的列线图。结果 共纳入4 687例晚期TNBC患者,与同期其他分子分型的乳腺癌相比较,TNBC的预后最差。单因素分析发现,年龄、性别、分期、手术、化疗、放疗、转移与更好的预后相关(P<0.05)。多因素分析发现年龄、性别、种族、分期、手术、化疗、放疗、各器官转移是患者预后的独立影响因素(P<0.05),并以此构建了列线图,其C-index为0.75(95％CI,0.71～0.79),校准图显示了预测的总生存期(OS)与观察到的OS之间的最佳一致性。结论 我们分析了晚期TNBC的临床特征,为TNBC患者的OS提供了一些预后因素,并根据这些预后因素制定了列线图,帮助临床医生进行风险管理并选择TNBC患者的长期生存策略。

Objective To analyze the risk factors of advanced triple-negative breast cancer (TNBC) and establish an effective prognostic nomogram. Methods Screening patients with advanced TNBC by searching the SEER (surveillance, epidemiology, and end results) database, using univariate and multivariate analysis to determine the independent prognostic factors of advanced TNBC, and constructing a nomogram based on it. Results A total of 4 687 patients with advanced TNBC were included. Compared with other types of breast cancer over the same period, TNBC had the worst prognosis. Univariate analysis found that age, gender, stage, surgery, chemotherapy, radiotherapy, and metastasis were associated with a better prognosis (P<0.05). Multivariate analysis found that age, gender, race, stage, surgery, chemotherapy, radiotherapy, and metastasis of the organs were independent factors affecting the prognosis of patients (P<0.05), and constructed a nomogram with a C-index of 0.75 ( 95% CI, 0.71～0.79). The calibration chart showed the best agreement between the predicted overall survival (OS) and the observed OS. Conclusion We analyzed the clinical features of advanced TNBC, provided some prognostic factors for the OS of TNBC patients, and developed a nomogram based on these prognostic factors to help clinicians manage risk and choose long-term survival strategies for TNBC patients.

Objective To explore the application value of painless gastroscope in the removal of foreign body in upper gastrointestinal tract. Methods The study involved patients who visited at the department of endoscopy center at Hospital (Dongguan, China). Retrospective analysis of patients undergoing endoscopic removal of foreign bodies in the upper gastrointestinal tract from May 1, 2017 to May 1, 2020. We analyzed the patients' clinical data and compared the diagnosis and treatment effect between the painless gastroscope group and normal gastroscopy group. Results A total of 357 patients were included, 372 times of removal of foreign body under gastroscope were conducted. A total of 99 cases in painless gastroscope group were treated by painless gastroscope with painless sedation, 273 cases in normal gastroscopy group were treated by normal gastroscopy, among them, 15 cases were failed to removal the foreign body treated by normal gastroscopy, and turned into the painless sedation gastroscopy. Finally, 10 patients with foreign bodies were not removed and transferred to surgical department or higher level hospitals. In the treatment of endoscopic foreign body removal, the success rate of painless gastroscope group was higher (P<0.05), the complication incidence of mucosal injury, bleeding and perforation and cost per capita were lower than that of normal gastroscopy(P<0.05). Following painless sedation, the blood oxygen saturation, blood pressure dropped (P<0.05) and heart rate increased (P<0.05), the effect of the sedatives on the elderly was the most obvious (P<0.05), but it did not affect the patient's endoscopic operation, and the heart rate, blood oxygen saturation and blood pressure (P>0.05) after awakening. Conclusion Painless gastroscope in the removal of foreign body in upper gastrointestinal tract is safe, effective high success rate, less medical cost, and easy for patients to accept, it should be widely applied.

Objective To observe the effect of wearing an elastic soft occlusal splint on the stress of periodontal tissue in patient with bruxism. Methods A three-dimensional finite element model of jaw and dentition was created. Each tooth in the test area was loaded with the maximum adult occlusal force at 0°, 45°, and 90° with respect to the long axis of the tooth. 1 mm and 2 mm elastic soft occlusal splint were used, and the stress of the alveolar bone and periodontal ligament with and without elastic soft occlusal splint were analyzed and compared. Results Compared with the control group, 1 mm splint reduced the periodontal ligament stress of patient by an average of 16% and the alveolar bone stress by an average of 15%. After wearing a 2 mm splint, the patient's periodontal ligament and alveolar bone stress were reduced by 26% and 25% respectively. In all groups, the maximum stress of the periodontal tissue was on the buccal and lingual alveolar ridge crest, but the stress distribution was more uniform after using the soft occlusal splint. Conclusion The soft occlusal splint can be used to relieve occlusal stress and help eliminate the damage to periodontal tissue caused by the extra stress in bruxism.
