Objective:To analyze the changes of mean arterial pressure (MAP) and end expiratory carbon dioxide (ETCO 2) in patients after emergency endotracheal intubation (ETI). To explore the values of MAP and ETCO 2 monitoring in early prediction of severe cardiovascular collapse (CVC) after emergency ETI. Methods:The clinical data of adult patients who underwent ETI from March 2015 to May 2020 were collected consecutively in the emergency departments of Peking Union Medical College Hospital. The values of MAP and ETCO 2 were observed and recorded at 5, 10, 30, 60 and 120 min after intubation. According to whether severe CVC occurred after ETI, the patients were divided into the severe CVC group and non-severe CVC group. The values of MAP and ETCO 2 were compared at the same time points between the two groups and the adjacent time points within the groups. The correlation between MAP and ETCO 2 after ETI was also analyzed. ROC curve was used to analyze the ability of MAP and ETCO 2 at 5 min and 10 min after ETI to predict severe CVC. Results:Totally 116 patients were enrolled in this study, among them 75 (64.7%) cases had severe CVC after ETI. The majority were male and elderly patients in the severe CVC group. The values of MAP and ETCO 2 in 5, 10, 30, 60 and 120 min after ETI in severe CVC group were significantly lower than those in the non-severe CVC group. The values of MAP and ETCO 2 in the two groups showed simultaneous decrease from 5 min to 30 min after ETI, reached the lowest value at 30 min after ETI, and appeared the synchronous recover from then to 120 min after ETI. After ETI, the changes of MAP was correlated with that of ETCO 2 ( rs = 0.653, P<0.01). At 5 min after ETI, MAP could predict severe CVC (AUC=0.86, P<0.01), MAP≤72 mmHg was the best cutoff value (sensitivity 78.7%, specificity 87.8%); ETCO 2 could also predict severe CVC (AUC=0.85, P<0.01), and ETCO 2≤35 mmHg was the best cutoff value (sensitivity 77.3%, specificity 85.4%). At 10 min after ETI, MAP could predict severe CVC (AUC = 0.90, P<0.01), MAP≤67 mmHg was the best cutoff value (sensitivity 89.3%, specificity 85.4%), ETCO 2 could also predict severe CVC (AUC=0.87, P<0.01), and ETCO 2≤33 mmHg was the best cutoff value (sensitivity 81.3%, specificity 78.0%). There was no significant difference in the ability of prediction between any two indexes of the MAP and ETCO 2 at 5 min and 10 min after ETI ( P>0.05). Conclusions:Patients with severe CVC after ETI have early signs of decreased MAP and ETCO 2, but the delayed recognition and insufficient intervention may be related to the occurrence and development of severe CVC. MAP and ETCO 2 at the early stage after ETI have high accuracy in predicting severe CVC. MAP≤72 mmHg, ETCO 2≤35 mmHg at 5 min after intubation, MAP≤67 mmHg and ETCO 2≤33 mmHg at 10 minutes after intubation all suggest the possibility of severe CVC.

Objective:To investigate the clinical significance of the primary tumor size in patients with endometrial carcinoma (EC).Methods:A total of 385 patients with EC admitted to Peking University People's Hospital from January 2006 to December 2016 with complete follow up data were selected, whose tumor size data before biopsy were retrospectively studied.Results:(1) The mean diameter of the primary tumor was (3.6±1.8) cm (range: 1-15 cm). And 48 cases were 0-<2 cm, 78 cases were 2-<3 cm, 92 cases were 3-<4 cm, 73 cases were 4-<5 cm, 94 cases were ≥5 cm. The diameter of the tumor was associated with age <60 years old, premenopause, CA 125≥35 kU/L, non-parturition, poor differentiation, stage Ⅲ-Ⅳ, depth of myometrial infiltration ≥1/2, cervical interstitial involvement, adnexal metastasis and lymph node metastasis (all P<0.05), but not associated with body mass index, hypertension, diabetes mellitus, pathology, lymph-vascular space invasion (all P>0.05). (2) Among the 334 patients underwent lymphadenectomy, 45 (13.5%, 45/334) cases with lymph node metastasis were observed. Stratified analysis showed that lymph node metastasis and recurrence rate of patients with EC gradually increased with the increase of tumor size ( P<0.05). Adopting 2, 3, 4 and 5 cm as cut-off values of tumor size, there were significant differences in the rate of lymph node metastasis and recurrence among them observed ( P<0.05), except for lymph node metastasis rate and recurrence rate when the cut-off value was 2 cm ( P>0.05). (3) An receiver operating characteristic (ROC) curve analysis showed that a tumor diameter of 4.25 cm was the cut-off prognostic value to predict lymph node metastasis and recurrence of EC. Conclusions:Tumor diameter is significantly correlated with lymph node metastasis and recurrence in patients with EC. Tumor size should be considered in determining the scope of surgery and adjuvant therapy.

0bjective:
To establish a three-dimensional finite element model of mandible and study the transverse displacement of proximal segment after Bilateral Sagittal Split Ramus Osteotomy (BSSRO) with different retrogression amounts during mastication.
Methods:
DICOM data of a skull model were processed with MIMICS and ANSYS software, reconstructing the 3D model including the teeth and temporomandibular joint in order to simulate BSSRO and evaluate the transverse displacement of proximal segment with different retrogression amounts during mastication.
Results:
The mean of proximal segment width change were 2.955 mm and 3.490 mm, when retrogression amounts of distal segmentwere 3 mm and 8 mm, respectively.No significant difference between the two groups were found (P=0.131). Meanwhile the displacement color scale of the 3D finite element models showed that the apparent transverse displacement distribution of the proximal segment was measured around the gonial area, decreased from the exterior to the interior.
Conclusions
The mandibular angle width was significantly expanded right after BSSRO. The masticatory muscle system and single cortical fixation system played an important role in expanding the width of proximal segment. However there was no correlation between the widening effect and retrogression amounts of distal segment of mandible.
