RESUMEN
Objective:To explore the application effects of standardized patient (SP) and breast visual palpation simulation system on clinical probation of breast surgery for medical students.Methods:A total of 110 students were randomly divided into experimental group and control group, and each group was further divided into 5 subgroups. In the experimental group, SP scripts of five common diseases in breast surgery department were designed according to the syllabus before probation, and the teachers were trained. During the probation, we first talked about the characteristics of disease diagnosis and treatment, and then the five subgroups collected the history of the disease according to the SP of different diseases mentioned above, and checked the corresponding lesions on the breast visual palpation simulation system. In the physical examination, SP responded to the students' questions. The control group also talked about the above-mentioned five diseases during the probation, and then the five subgroups carried out history collection and physical examination for specific patients in the hospital. Finally, the teaching effects were analyzed through medical record writing, theoretical examination, physical examination and student evaluation. SPSS 26.0 was used for chi-square test (or Fisher exact test) and Mann-Whitney U test. Results:There was no significant difference in the theoretical examination between the two groups. It was demonstrated that the correct rate of experimental group was significantly higher than that of the control group in medical history collection, especially in the main symptoms, incentives, aggravation and remission factors, accompanying and differential symptoms and so on. And the positive results of breast, nipple and axillary lymph node palpation in the experimental group were significantly higher than those in the control group through the physical examination operation of breast visual palpation simulation system. The analysis of students' evaluation showed that the teaching efficiency of the experimental group increased, and the students' satisfaction was improved (satisfaction rate: 92.73% vs. 76.36%).Conclusion:The application of SP and breast visual palpation simulation system in breast surgery probation teaching can not only protect the privacy of clinical patients, but also improve the teaching effects, which can be popularized in the clinical teaching of breast surgery.

Objective:To compare the therapeutic effects of microdissection tungsten needle and high-frequency electrosurgical generator on open thyroid surgery.Methods:95 patients who underwent open thyroid surgery from Jan. 2017 to Dec. 2017 in the Department of Breast and Thyroid Surgery, Daping Hospital of Army Military Medical University were divided into microdissection tungsten needle group ( n=50) and high-frequency electrosurgical generator group ( n=45) according to different methods. The operation time, intraoperative blood loss, postoperative drainage volume, postoperative complication rate and recurrence and metastasis rate of the two groups were compared. Results:There were no significant differences in operation time (79.3±14.7 vs 73.7±13.9, t=1.914, P=0.059) , intraoperative blood loss (31.8±9.7 vs 30.3±10.6, t=0.702, P=0.484) and postoperative drainage volume (67.3±13.0 vs 71.3±10.8, t=-1.650, P=0.102) between the two groups ( P>0.05) . There were significant differences between the two groups in temporary recurrent laryngeal nerve (RLN) injury (2% vs 17.8%,χ 2=5.518, P=0.023) and temporary hypoparathyroidism (18% vs 44%,χ 2=7.810, P=0.005) , and the results of the microdissection tungsten needle group were better than high-frequency electrosurgical generator group ( P<0.05) . There were no permanent RLN and permanent hypoparathyroidism in the two groups. There were no recurrence and metastasis during the follow-up period. Conclusions:The microdissection tungsten needle is superior to the high-frequency electrosurgical generator in the protection of RLN and parathyroid gland in open thyroid surgery, which is worthy of promotion in clinical application.

RESUMEN
Objective To investigate clinical significance of transforming growth factor-beta 1 ( TGF-β1 ) in patients with chronic idiopathic thrombocytopenic purpura(CITP). Methods The serum level of TGF-β1 in 38 pa-tients with initial CITP were detected using enzyme-linked immunosorbent assay(ELISA). Results The serum level of TGF-β1 in initial patients with CITP was significantly higher than that of the controls [( 132.57±5.17) μg/L vs ( 76.81±4.42) μ/L] ( P <0.01 ). The serum level of TGF-β1 in those having good response after therapy was sig-nificantly lower than before treatment[(81.26±3.78)μg/L] (P <0.01 ). There was no difference in TGF-β1 be-tween nonremission [(123.49 ± 4.31 ) μg/L] and initial patients (P > 0.05 ). There was negative correlation between TGF-β1 and platelet count(r = -0. 342 ,P < 0.05 ) ,there was positive correlation between TGF-β1 and megakaryo-cyte count (r = 0.409, P < 0.01 ). Conclusions TGF-β1 partakes in the pathogenesis of CITP, the determination of which in patients with CITP is useful to judge the state of illness, which can be regarded as an assistant index of cur-ative effect.
