The hospital the authors work with started to implement a personnel mechanism based on employment under contract. The organizational structure was delimited scientifically and the posts were set up rationally. The employees had to compete for the posts and were appointed according to their merits. As a result, their work enthusiasm and initiative were aroused, their awareness of competition and sense of crisis were enhanced, and the allocation of personnel was optimized. When implementing the competition for the posts system, it is imperative to adhere to such principles as the combination of democracy and centralism, the combination of competition for the posts and comprehensive assessment, and the combination of competition and unity and cooperation.

Objective The results of Aortic valve replacement (AVR). Combined with ascending aortic replacement(group A) or aortoplasty (group B) in patients with aortic valve disease and ascending aortic dilatation were analysed to assess the clinical outcomes and respective indications. Methods Among the two groups, the age, gender, NYHA class, types of aortic valve lesions and left ventricular ejection fraction were not different statically. The ascending aortic diameters in group A[(50.41 ±3.71) mm] and group B [(48.29±2.18) mm] were not statically different. Ascending aortic replacement was performed in Group A. A Dacron tube(diameter 28 ~ 30mm) was routinely wrapped around the ascending aorta after aortoplasty in group B. Results There was 1 postoperative death in group B, blood transfusion volume and postoperative complications were not stasticaly different in the two groups. Cardiopulmonary bypass time [(110.52 ± 27.51) min] and aortic across clumping time [(71.70 ± 17.13)min] in group A were significantly longer than that of group B [(97.31 ± 19.46) min,P=0. 004; (57.13 ±19.46) min, respectively. P=0.025]. Conclusion Aortic valve disease, especially bicuspid valve disease often combines with ascending aortic dilatation or aneurysm. In younger patients, ascending aorta should be actively treated surgically when the diameter is equal or more than 40mm. Aortoplasty with external reinforcement of a Dacron tube is simpler and safer than aortic replacement in patient without aortic atherosclerosis or ulceration, and large aneurysm.

Objective:To evaluate the efficacy and safety of lopinavir/ritonavir (LPV/r) and arbidol in treating patients with coronavirus disease 2019 (COVID-19) in the real world.Methods:The clinical data of 178 patients diagnosed with COVID-19 admitted to Guangzhou Eighth People′s Hospital from January 20 to February 10, 2020 were retrospectively analyzed. According to patient′s antiviral treatment regimens, 178 patients were divided into 4 groups including LPV/r group (59 patients), arbidol group (36 patients), LPV/r plus arbidol combination group (25 patients) and the supportive care group without any antiviral treatment (58 patients). The primary end point was the negative conversion time of nucleic acid of 2019 novel coronavirus (2019-nCoV) by pharyngeal swab.Results:The baseline parameters of 4 groups before treatment was comparable. The negative conversion time of viral nucleic acid was (10.20±3.49), (10.11±4.68), (10.86±4.74), (8.44±3.51) days in LPV/r group, arbidol group, combination group, and supportive care group respectively ( F=2.556, P=0.058). There was also no significant difference in negative conversion rate of 2019-nCoV nucleic acid, the improvement of clinical symptoms, and the improvement of pulmonary infections by CT scan ( P>0.05). However, a statistically significant difference was found in the changing rates from mild/moderate to severe/critical type at day 7 (χ 2=9.311, P=0.017), which were 24%(6/25) in combination group, 16.7%(6/36) in arbidol group, 5.4%(3/56) in LPV/r group and 5.2%(3/58) in supportive care group. Moreover, the incidence of adverse reactions in three antiviral groups was significantly higher than that in supportive care group (χ 2=14.875, P=0.002). Conclusions:Antiviral treatment including LPV/r or arbidol or combination does not shorten the negative conversion time of 2019-nCoV nucleic acid nor improve clinical symptoms. Moreover, these antiviral drugs cause more adverse reactions which should be paid careful attention during the treatment.

Objective To analyze the feasibility of totally no tube (TNT) in da Vinci robotic mediastinal mass surgery and its significance for fast track surgery. Methods A total of 79 patients receiving robotic mediastinal TNT surgery in the General Hospital of Shenyang Military Command from January 2016 to December 2017 were enrolled as a TNT group; 35 patients receiving robotic mediastinal surgery in General Hospital of Shenyang Military Command from January 2014 to December 2017 and 54 patients receiving thoracoscopic mediastinal surgery during the same period were enrolled as a non-TNT group and a video-assisted thoracoscopic surgery (VATS) group. The muscle relaxation and tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, postoperative ICU stay, postoperative hospital stay, postoperative visual analogue scale (VAS), hospitalization costs and postoperative complications and other related indicators were retrospectively analyzed among the three groups. Results Surgeries were successfully completed in 168 patients with no transfer to thoracotomy, serious complications (postoperative complications in 9 patients) or death during the perioperative period. All patients were discharged. Compared with the non-TNT group, the TNT group had significantly less muscle relaxation-tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, VAS pain score, ICU stay, postoperative hospital stay (P<0.01); there was no significant difference in the total cost of hospitalization between the two groups (P>0.05). Between the non-TNT group and the VATS group, there was no significant difference in time of muscle relaxation and tracheal intubation, operation time and ICU stay (P>0.05). The non-TNT group was superior to the VATS group in terms of intraoperative blood loss, VAS pain scores on the following day after operation, chest drainage volume 1-3 days postoperatively, postoperative catheterization time and postoperative hospital stay (P<0.05); but the cost of hospitalization in the non-TNT group was significantly higher (P=0.000). Conclusion The da Vinci robot is safe and feasible for the treatment of mediastinal masses. At the same time, TNT is also safe and reliable on the basis of robotic surgery which has many advantages such as better comfort, less pain, ICU stay and hospital stay as well as faster recovery.

Objective To study the clinical characteristics, therapy strategies and the outcomes of female patients with acute aortic dissection during late pregnancy and puerperal period. Methods We retrospectively analyzed the clinical data of 7 patients with acute aortic dissection during late pregnancy and puerperal period in Shanghai Changhai Hospital between August 2012 and June 2017. Five of the 7 patients were late stage pregnancy, 2 were puerperal period (1 at the postpartum night, 1 in 18 days after delivery). There were 6 patients of Stanford type A aortic dissection (85.7%), and 1 patient of type B aortic dissection (14.3%). The age of the patients ranged from 26 to 34 (30.8±3.1) years. Cardiac ultrasonography of patients with type A showed that the maximum diameter of the ascending aortas was 4.2–5.7 (4.7±0.6) cm, of which 2 patients were aneurysm of aortic sinus, 3 patients were with Marfan syndrome. Bentall procedure was conducted in 1 patient, Bentall+Sun’s surgery in 2 patients, ascending aorta replacement+Sun’s+coronary artery bypass grafting surgery in 1 patient, aortic root remodeling+ascending aorta replacement+Sun’s surgery in 2 patients. One patient with Stanford type B acute aortic dissection was performed with thoracic endovascular aortic repair (TEVAR) after cesarean section. Results Aortic blocking time ranged from 51 to 129 (85.5±22.9) min. Cardiopulmonary bypass time was 75–196 (159.0±44.0) min. Moderate hypothermic circulation arrest with selective cerebral perfusion time was 20–30 (23.8±3.5) min. All maternal and fetuses survived. The infant whose mother received aortic repair in early stage and then received cesarean section was diagnosed with cerebral palsy. Maternal and fetuses were followed up for 9 months to 4 years. During the follow up period, all the fetuses grew well except the cerebral palsy one, and all maternal recovered well. The patient who received aortic repair in the early stage, had a sigmoid rupture during cesarean section and was treated with sigmoid colostomy. Another patient with Stanford type A dissection was diagnosed as left renal vein entrapment syndrome after 2 years. Conclusion Type A aortic dissection is more common in late pregnancy and puerperal patients. And Marfan syndrome is a high-risk factor for acute aortic dissection in pregnancy women. Early and appropriate surgical treatment strategy based on the type of aortic dissection and gestational age are the key points to achieve good outcomes both for maternal and fetus.
