Medical simulation teaching is an emerging and developing teaching method in our coun-try. At present, the simulation teaching centers are developing rapidly in higher education institutions, but how to improve the effectiveness in the operation of the centers is still a subject that needs to be discussed. Based on our own experience, this paper analyzes the related factors in developing medical simulation teach-ing centers, making summary and demonstrations from aspects of team building, teacher training, docking needs, staffing and so on, so as to provide references and suggestions for the construction of medical simu-lation center higher education institutions.

Objective To determine the effect of obesity on prostate specific antigen (PSA) in men with benign prostatic hyperplasia (BPH) and develop a PSA-related parameter that can eliminate the effect of obesity. Methods We reviewed the clinical data of 706 patients with BPH. Two PSA-related parameters, namely PSA mass (total circulating PSA protein) and PSA mass ratio (total circulation PSA protein per prostate volume), were calculated for all the patients and the association of BMI with PSA, PSA mass, and PSA mass ratio was assessed. Results A higher BMI was significantly associated with a greater plasma volume and prostate volume (P<0.05). Linear regression analysis revealed a greater adjusted R2 of BMI versus plasma volume than of BMI PSA (0.569 vs 0.027). PSA was positively associated with the prostate volume and negatively with BMI and plasma volume (P<0.05). PSA mass was positively associated with prostate volume (P<0.05) but was not associated with BMI or plasma volume (P>0.05). PSA mass ratio was not associated with prostate volume (P>0.05) but negatively associated with BMI and plasma volume. Plasma volume and prostate volume, PSA, and PSA mass ratio (P<0.05), but not PSA mass (P>0.05), differed significantly among normal-weight, overweight, and obese patients. Conclusion A higher BMI is associated with a greater plasma volume in BPH patients. In obese patients with BPH, a lower PSA concentration may result from hemodilution caused by a greater plasma volume, and PSA mass can eliminate the effect of obesity on PSA.

Objective To explore the early laboratory indicators for risk of intravenous immunoglobin-resistant Kawasaki diseases. Methods The clinical data were retrospectively analyzed in 881 Kawasaki disease patients (group A: 26 cases of intravenous immunoglobin-resistant; group B: 855 cases of intravenous immunoglobin-sensitive) from July 1, 2015 to June 30, 2016. After 1:3 matching with age and sex, the regression model for each of variables including sex, age, fever days, temperature, red blood cell count (RBC), white blood cell count (WBC), neutrophil (N), lymphocyte (L), platelet count (PLT) and C reactive protein (CRP), was constructed by conditional logistic regression analysis. Results Compared with group B, group A had significantly lower RBC count and higher PLT (P<0.05). Logistic regression analysis showed that, with the age, the regression model was Y=-2.87+0.01×PLT (PLT OR=1.01, 95％ CI: 1.00～1.01, P<0.01); with the sex, Y=-32.98+0.44×WBC+0.28× N+0.01×PLT (WBC OR=1.55, 95％ CI: 1.17～2.05, P<0.01; N％ OR=1.32, 95％ CI: 1.04～1.68, P<0.05; PLT OR=1.01, 95％ CI 1.00～1.01, P<0.01). Conclusion In case that abnormally high levels of PLT exist in confirmed Kawasaki disease, it should be aware of possibility of the intravenous immunoglobin-resistant Kawasaki disease.

Objective:To explore the establishment and assessment of the depression model of adult SD rats induced by early maternal infant separation stress combined with adult chronic unpredictable mild stress(CUMS), and to observe the behavior and synaptic protein expression of SD rats.Methods:Twenty-four male rats were randomly divided into three groups: control group (CON group), chronic unpredictable stress group (CUMS group), maternal infant separation combined with chronic unpredictable stress group (MS + CUMS group). The depression model of rats in cums group was established by CUMS, and the depression model of rats in MS + CUMS group was established by maternal infant separation + CUMS. The depression model was evaluated by body mass and appearance observation, sugar water preference experiment, open field test and forced swimming test.Synapse-associated proteins (PSD-95 and synaptophysin (Syn)) of the hippocampus were assayed using Western blot. Syn protein expression was measured by immunohistochemistry.Results:After modeling, compared with CON group, the rats in CUMS group and MS + CUMS group had significantly lower body mass((126.43±3.88) g, (91.04±3.85) g, (69.89±6.67) g; t=5.03, 8.03, both P<0.01), significantly lower sugar water preference((94.21±0.56)%, (79.30±1.13)%, (72.73±1.82)%; t=8.24, 11.87, both P<0.01) and significantly increased immobility time((3.50±0.84)s, (13.59±2.40)s, (15.70±2.97)s; t=3.16, 3.82, both P<0.01). Among them, the body mass and sugar water preference of MS + CUMS group were lower than those of CUMS group ( t=3.00, 3.63; both P<0.01). (2)The center time of the rats in MS+ CUMS group markedly reduced compared with that of CON group((21.41±4.65) s, (8.96±2.37) s; t=2.66, P<0.05). (3)In the immunohistochemistry experiment, compared with the CON group, the percentage of Syn positive area in hippocampus of rats in CUMS group and MS+ CUMS group decreased significantly ((24.42±0.76)%, (14.00±0.95)%, (10.38±1.38)%; t=6.93, 9.33, P<0.01). (4)The results of Western blot showed that compared with CON group, both the expression of PSD-95 ((1.18±0.02), (0.74±0.06), (0.52±0.05), t=6.29, 9.31; both P<0.05) and Syn ((1.12±0.08), (0.95±0.06), (0.90±0.07); t=3.10, 4.04; both P<0.05) in hippocampus of rats in CUMS group and MS+ CUMS group were significantly decreased.And compared with the CUMS group, the expression of PSD-95 in MS+ CUMS group was lower( t=0.93, P<0.05). Conclusion:The method of MS combined with CUMS can effectively induce depression like behavior and decrease the expression of synaptic plasticity related protein of hippocampus in rats.

Objective:To investigate the efficacy of treatment of bromhidrosis by cutting off the apocrine glands under direct vision combined with micro electrocoagulation.Methods:From January 2017 to December 2017, 25 patients (50 sides) with axillary osmidrosis admitted to the First People’s Hospital of Yuhang District were treated with direct vision cutting and micro electrocoagulation to destroy the apocrine sweat glands, including 13 males and 12 females, aged 14-38 years, with an average age of 23 years. According to Young-Jin Park′s criteria for judging axillary osmidrosis, 21 cases were classified as grade 3 and 4 cases as grade 2. After tumescent anesthesia, the subcutaneous apocrine sweat glands, fat and hair follicles were cut off under direct vision. The subdermal vascular network was preserved, and the basement was destroyed one by one by using high-frequency electrocoagulation mode. After the operation, the evaluation was conducted according to the criteria for judging axillary osmidrosis formulated by Young-Jin Park.Results:The symptoms of axillary osmidrosis reached the standard of cure in 24 patients after operation, 1 case failed to reach the cure standard. Among the patients who reached the standard, there were 2 cases of necrosis of the skin flap and 1 case of hematoma after operation unilaterally, which were given actively dressing change, secondary debridement, suturing and hematoma removal, The follow-up period was 6 months to 1 year. During the follow-up period, 24 cases were cured, including 21 cases of grade one and 3 cases of grade zero. The treatment effect was stable.Conclusions:The treatment of axillary osmidrosis by cutting off the apocrine sweat glands under direct vision combined with micro electrocoagulation, exposing the apocrine sweat glands as much as possible, effectively removing the apocrine sweat glands and hair follicles, and reducing the recurrence rate of axillary osmidrosis. It is a simple, safe and effective treatment technology for axillary osmidrosis.
