Plastic and Aesthetic surgery is a science which creates beauty by combining know-ledge and art. Combined with the professional characteristics of plastic surgery, we reformed the cur-riculum content and teaching mode of continuous education, including a established interactive theoret-ical learning model based on Journal club, the strengthening of clinical practice integrated with multiple related disciplines, the expanding the knowledge of Sociology, Psychology and Ethics, and the construc-tion of a long-term platform of network resources. Therefore, a comprehensive and specialized continu-ous education model in the department of plastic and aesthetic surgery was ultimately formed, whose preliminary assessment was favorable, and could be helpful in the cultivation of high-quality plastic and aesthetic surgeons in the future.

Objective serous endotoxin(ET) were measured to determine the relationship between serous endotoxin and differ‐ent type of intestinal obstruction in children .Methods 25 inguinal hernia patients and 43 intestinal obstruction patients were classi‐fied into control group(n=25) ,incomplete intestinal obstruction (n=20) and complete intestinal obstruction group without necrosis of intestine (n=23) according to degree of obstruction .Serous endotoxin were measured in different time (the day of admission ,one day after admission or ,preoperation and one day postoperation ) ,and t test is used to determine the difference between them . Results ET in different group was(6 .53 ± 14 .96) ,(4 .40 ± 1 .15) ,(4 .20 ± 1 .20) ,(4 .09 ± 1 .31) ,(3 .70 ± 1 .46)EU/mL ,respec‐tively .There were no difference between each group .Conclusion ET examination suggests there is no difference between different type of intestinal obstruction in children and endotoxemia is not found in intestinal obstruction according to the results .

Objective To evaluate the value of captopril challenge test (CCT) in the diagnosis of primary aldosteronism (PA).Methods A total of 674 patients [(45.0±13.7) years, men 341, women 333] admitted to Peking Union Medical College Hospital from 2000 to 2015 were analyzed.Among them, 222 subjects were with essential hypertension (EH), 28 were with pheochromocytoma (PHEO), 246 were with idiopathic hyperaldosteronism (IHA) and 178 were with aldosterone producing adenoma (APA).All patients received CCT.24 h urine sodium was measured in partial patients.Plasma renin activity (PRA), aldosterone (ALD) were detected.Results Compared with EH [PRA: before 0.5(0.2,0.9) μg·L-1·h-1, after 0.8(0.4,1.5) μg·L-1·h-1;ALD: before (393±122) pmol/L, after (360±97) pmol/L] and PHEO [PRA: before 0.3(0.1,0.9) μg·L-1·h-1, after 0.4(0.1,1.6) μg·L-1·h-1;ALD: before (396±108) pmol/L, after (374±114) pmol/L], lower levels of PRA and higher levels of ALD before and after CCT were observed in PA patients [PRA: before 0.1 (0.1,0.2) μg·L-1·h-1, after 0.1 (0.1,0.2) μg·L-1·h-1;ALD: before (468±216) pmol/L;after (457±199) pmol/L].After CCT, the suppression rate of ALD [2.8% (-8.8%,15.4%) vs 6.6% (-4.3%, 17.6%)] and increasing rate of PRA [0(0,50%) vs 50%(0, 200%)] in PA patients were lower than those in EH patients.The ALD/PRA ratio (ARR) were higher in PA than that in EH or PHEO patients.In the EH subjects, ALD levels of seated posture were higher than those of recumbent posture both before and after receiving captopril, but with no changes in ARR after CCT.No significant differences in ALD and ARR (before and after receiving captopril) were observed between seated and recumbent position in the PA group.The ARR after CCT tended to decrease in EH subjects with elevated urine-sodium compared with those with normal urine-sodium.No changes could be viewed in ALD and PRA levels between normal urine-sodium and elevated urine-sodium groups among APA, IHA and EH patients either before or after CCT.Among patients with APA, the ALD levels before CCT and the ARR after CCT were lower in the patients with AngiotensionⅡ(AngⅡ) reactive than those without.A ROC curve analysis suggested that the optimal cutoff value was 46.2 (ALD unit:ng/dl;PRA unit:μg·L-1·h-1) for ARR after challenge in diagnosing PA, with the sensitivity of 88.7% and specificity of 84.8%.Conclusions ARR after 25 mg captopril had high sensitivity and specificity in diagnosis of PA with the cutoff of 46.2.Seated CCT could replace recumbent CCT as a more confirmatory test.The PRA increasing rate should be taken into consideration when diagnosis of PA.

The severe fever with thrombocytopenia syndrome virus (SFTSV) is a new member in the genus Phlebovirus of the family Bunyaviridae identified in China. The SFTSV is also the causative pathogen of an emerging infectious disease: severe fever with thrombocytopenia syndrome. Using immunofluorescent staining and confocal microscopy, the intracellular distribution of nucleocapsid protein (NP) in SFTSV-infected THP-1 cells was investigated with serial doses of SFTSV at different times after infection. Transmission electron microscopy was used to observe the ultrafine intracellular structure of SFTSV-infected THP-1 cells at different times after infection. SFTSV NP could form intracellular inclusion bodies in infected THP-1 cells. The association between NP-formed inclusion bodies and virus production was analyzed: the size of the inclusion body formed 3 days after infection was correlated with the viral load in supernatants collected 7 days after infection. These findings suggest that the inclusion bodies formed in SFTSV-infected THP-1 cells could be where the SFTSV uses host-cell proteins and intracellular organelles to produce new viral particles.

Objective To summary and explore the indications,safety and effectiveness of no touch ostial cardioplegia delivery method during aortic valve replacement(AVR) for severe aortic insufficiency(AI),in order to provide guidance for clinical application.Methods Between September 2012 and February 2015,63 cases were randomly divided into two groups,in study group we used this technique in 31 patients with a mean age of(58.0 ± 15.0) years and a range of 31 to 74 years old.The degree of AI averaged (3.5 ± 0.5) according to a semiquantitative 5-grade scale[1].32 patients were enrolled in control group with a mean age of(60.4 ± 9.4) years and a range of 22 to 73 years old.The degree of AI averaged (3.6 ± 0.5).The abnormal aortic cusps were sutured though the aortic incision,which would be closed temporarily.Blood cardioplegia was infused repeatedly into the coronary osita through the closed aortic incision during the remainder of the procedure except AVR,when the closed aortic incision was reopened.Results In the study group,spontaneous resumption of nodal and normal sinus rhythm shortly after the removal of aortic cross-clamp was achieved in all patients,no hearts had to be electrically defibrillated and electrocardiogram showed no obvious S-T segment elevation.The time from cross-clamp removal to sinus rhythm was(12.3 ± 7.7) minutes in the study group,versus (18.6 ± 8.2) minutes in the control group(P =0.037).No operative mortality occurred in both groups.There was a significant increase in left ventricular ejection fraction[from(0.54 ± 0.09) preoperatively to(0.62 ± 0.06) postoperatively] (P =0.005) in patients of the study group,which was not seen in patients of the control group.Conclusion Preliminary results have shown that the no touch ostial cardioplegia delivery method is a feasible method for cardioplegia infusion during aortic valve replacement in patients with severe AI.

Objective:To investigate the mechanism of liver and lung injury in mouse septic models.Methods:Twenty-four male Kunming mice were subjected to cecal ligation and puncture(CLP)or sham operation.The permeability of microvasculature,water contents,activities of myeloperoxidase(MPO)and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation.Results:Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group.MPO activity and water content in CLP group were obviously higher than those in the sham operation group.The apoptosis of lung microvascular endothelial cells at 12 h in CLP group(5.03?0.92)% was significantly higher than that of control group(3.48?1.21)%(P

Objective To investigate the effects of low frequency ultrasound (LFU) on the proliferation and apoptosis of smooth muscle cells (SMCs) in rabbits with carotid atherosclerosis(CA).Methods CA models were established in 30 New Zealand rabbits using a high fat diet and air-drying.They were randomly divided into a control group and four LFU groups:group A received 0.5 W/cm~2 LFU for 5 min/d,group B 0.5 W/cm~2 for 10 min/d, group C 1 W/cm~2,5 min/d,and group D 1 W/cm~2,10 min/d.The rabbits' carotid arteries were autopsied after 20 d of the LFU treatment.The expression of PCNA and TUNEL staining were used to explore the proliferation and apopto- sis of SMCs,and the proliferation rates (PRs) and apoptosis rates (ARs) were calculated.Results Compared with the control group,the PRs in groups B,C and D were significantly lower,while the ARs in groups B,C and D were significantly higher.There was no significant difference in ARs or PRs among groups B,C and D.Con- clusion LFU can induce SMC apoptosis and inhibit SMC proliferation in rabbits with CA.
