ABSTRACT
The teaching of orthognathic surgery is difficult because it is complex and emphasizes the combination of theory and practice. The traditional teaching method focuses on theoretical teaching, but due to the limitation of conditions, it is difficult for students to master the operation. In this paper, we apply the digital three-dimensional surgical simulation system combined with 3D printing in specialist training of orthognathic surgery. Digital software and 3D printing are applied in the theoretical teaching, surgical operation, summary and reflection to combine practical teaching with theoretical teaching, so as to stimulate the subjective initiative of the students. The results showed that the teaching evaluation of the experimental group [(3.89±0.84) points] was better than that of the control group [(2.91±1.21) points]. The application of digital three-dimensional surgical simulation system combined with 3D printing has achieved satisfactory results.
ABSTRACT
Objective To investigate the impact of body mass index (BMI) on short-term and long-term prognosis in the patients with ST-segment elevation myocardial infarction (STEMI).Methods The clinical data of inpatients with STEMI in our hospital during 2014 were retrospectively collected.The patients conforming to the inclusion and exclusion criteria were divided into 4 groups according to BMI,low BMI group (n=31),normal BMI group (n=139),overweight group (n=71) and obesity group(n=26).The clinical baseline data were analyzed and compared among 4 groups,and the all-cause mortality on 7 d and within 1 year after myocardial infarction(MI) was followed up.Results The higher the BMI increased,the younger the patient's onset age (P＜0.01),the smaller the female proportion(P=0.001),among them,the albumin and hemoglobin levels in the obesity group were relatively higher(P=0.004;P =0.006);the all-cause mortality at 1 year after MI was significantly decreased with BMI increasing (P =0.003),while which on 7 d after MI had no statistical difference (P=0.287).Conclusion BMI is correlated with the long-term prognosis in the patients with STEMI,and "obesity contradiction" phenomenon exists in the patients with STEMI.However,the influence of BMI on the prognosis in the patients with STEMI should be comprehensively evaluated by combining with the multiple factors such as the patient's age,sex,complications and medication therapy.

ABSTRACT
Objective:To determine the status of glucose intolerance in breast cancer patients without DM history after combined treatment with surgery and/or chemotherapy through an oral glucose tolerance test (OGTT). Methods:All 121 breast cancer patients more than 3 months after combined treatments with surgery and/or chemotherapy and without the diagnosis of diabetes underwent OGTT and fasting. Then, 2 h glucose levels were measured to identify glucose tolerance and diabetes. Meanwhile, six patients with a history of diagnosed diabetes did not undergo OGTT. Results:The median ages of all breast cancer patients and the mean duration after combined treatments with surgery and/or chemotherapy were 50.4 years and 19 months, respectively. Among the 121 breast cancer pa-tients without the history of diabetes, the incidences of diabetes, prediabetes, and normal glucose intolerance were 19.8%(24 cases), 45.5%(55 cases) and 34.7%(42 cases), respectively. Among all breast cancer patients, the incidences of previously diagnosed diabetes, undiagnosed diabetes, and prediabetes were 4.72%, 18.9%, and 43.3%, respectively. The ratio of previously undiagnosed diabetes was about 80%. About 80.0% of undiagnosed diabetes and 74.5% of prediabetes met the criteria for elevated 2 h plasma glucose levels through OGTT instead of elevated fasting glucose levels. Conclusion: Breast cancer patients during follow-up after combined treat-ments with surgery and/or chemotherapy highly suffer from glucose intolerance, with high incidences of undiagnosed diabetes and pre-diabetes. OGTT should be made for breast cancer patients after combined treatments for early diagnosis, prevention, and treatment of di-abetes.
