Objective To study the effect of edaravone on serum IL-6、TNF-α and neurologic functional in acute cerebral hemorrhage,discuss the protective mechanism of Edaravone on cerebral hemorrhage.Methods 80 casesof cerebral hemorrhage in 72h were randomly divided into treatment group(40 cases)and control group(40 cases),and the control group was given routine treatment,and the treatment group was administered with edaravone,30mg/d,for 14 days on the based treatment of the control group.The serum IL-6 and TNF-αwere detcted by ELISA before therapy and after treatment for 14 days.Neurological function deficit scores were utilized for assessment before given treatment.On the 21 th day after treatment,the patients were assessed again,and the efficacy was recorded.Results After 14 days treatment.the mean scale of NIHSS,the serum levels of IL-6 and TNF-α in treatment group were more obviously decreased than that in control group(all P＜0.05).Conclusion Edaravone could obviously alleviate inflammatory reaction on acute cerebral hemorrhage,which could effectively remove the generous free radicals and reduce the brain edema after intracerebral hemorrhage.So it could protect the tissue of brain.

Objective To investigate the clinical characteristics and related factors of metabolic disorder in acute cerebrevascular disease (ACVD) and to provide clinical basis for intervention of ACVD.Methods The clinical data of 202 healthy individuals (control group) and 621 cases of ACVD (341patients with cerebral infarction and 280 patients with cerebral hemorrhage) was analysed retrospectively.Based on the level of blood pressure,blood glucose and blood fat, 621 cases of ACVD were divided into me tabolism syndrome( MS ) group (hypertension + hyperglycemia + hyperlipidemia),two kinds of risk fatorsgroup (hypertension + hyperglycemia or hypertension + hyperlipidemia or hyperglycemia + hyperlipidemia),one kind of risk factor group (hypertension or hyperglycemia or hyperlipidemia) and no risk fastor group.Results Of the patients with cerebral infarction and cerebral hemorrhage 320 eases(93.8%) and 259 cases (92.5%) had hypertention,163 cases (47.8%) and 101 cases (36.1%) had hyperglycemia, 115 cases (33.7%) and 141 cases (50.4%) had hyperlipidemia, respectively. The blood pressure in one kind of risk factor group, two kinds of risk factors group and MS group was significantly higher than those in control group and no risk factor group,the body mass index (BMI), fasting plasma glucose (FPG),total cholesterol(TG)and low density lipoprotein cholesterol (LDL-C) in two kinds of risk factors group were higher than those in control group and no risk factor group (P <0.05). The age,BMI,blood pressure,FPG,TC,TG,high density lipoprotein cholesterol(HDL-C) and LDL-C had obvious correlation with ACVD. Conclusion ACVD is often combined with various kinds of metabolic disorders risk factors, suggesting that an effective control of metabolic disorders is benefit to intervention of ACVD.

Background and objective A solitary pulmonary nodule (SPN) is deifned as a round intraparenchimal lung lesion less than 3 cm in size, not associated with atelectasis or adenopathy. hTe aim of this study is to learn clinical experi-ence of the treatment of SPN with Da Vinci Surgical System. Methods A total of 9 patients with solitary pulmonary nodules (SPN) less than 3 cm in diameter was treated with Da Vinci Surgical System (Intuitive Surgical, California) in thoracic surgery department from General Hospital of Shenyang Militrary Region from November 2011 to March 2014. hTis group of patients included 3 males and 6 females, and the mean age was 51±9.9 yr (range:41-74 yr). Most of the patients were no obvious clini-cal symptoms (7 cases were found by physical examination, others were with cough and expectoration). hTeir median medical history was 12 mo (range:4 d-3 yr). All the lesions of patients were peripheral pulmonary nodules and the mean diameter of those was (1.4±0.6) cm(range:0.8-2.8 cm). Wedge-shaped resection or lobectomy was performed depending on the result of rapid pathology and systemic lymph node dissection was done for malignant leision. We used general anesthesis with double lumens trachea cannula. We set the patients in lateral decubitus position with jackknife. hTe patient cart enter from top of the patient. hTe position of trocars would be set according to the position of lesion. A 12 mm incision was positioned at the 8th intercostal space in the posterior axillary line as vision port, and two 8 mm incisions were positioned at the 5th intercostal space between the anterior axillary line and midclavicular line, and the 8th infrascapular line as robotic instrument ports about 10 cm apart from the vision port. One additional auxiliary small incision for instrument without retracting ribs was set at the 7th in-tercostal space in the middle axillary line. Results hTere were 4 benign leisions and 5 malignancies identiifed. Wedge-shaped resection was performed for 4 patients, lobectomy with systemic lymph node dissection for 3 patients (including 2 right middle lobectomies and 1 letf upper lobectomy) and wedge-shaped resection with systemic lymph node dissection for 2 patients of poor lung function. All of the 9 cases were completed with total robotic procedure without conversion. hTe pathological results included 3 inlfammatory pseudotumors, 1 hamartoma, 5 adenocarcinomas. All of the 29 patients were hospital discharged smoothly. hTe patients were followed up for 0.1-18.5 mo (median 11 mo) without recurrence or metastasis. Conclusion hTe SPN patients should be given active surgical treatments to improve the diagnose rate as well as the cure rate of early non-small cell lung cancer. Since da Vinci Surgical System is a safe and minimally invasive treatment for SPN, it has higher value to the diagnosis and treatment of SPN.

Background::With an increasing number of patients with hematological malignancies being treated with umbilical cord blood transplantation (UCBT), the correlation between immune reconstitution (IR) after UCBT and graft-versus-host disease (GVHD) has been reported successively, but reports on double-negative T (DNT) cell reconstitution and its association with acute GVHD (aGVHD) after UCBT are lacking.Methods::A population-based observational study was conducted among 131 patients with hematological malignancies who underwent single-unit UCBT as their first transplant at the Department of Hematology, the First Affiliated Hospital of USTC, between August 2018 and June 2021. IR differences were compared between the patients with and without aGVHD.Results::The absolute number of DNT cells in the healthy Chinese population was 109 (70-157)/μL, accounting for 5.82 (3.98-8.19)% of lymphocytes. DNT cells showed delayed recovery and could not reach their normal levels even one year after transplantation. Importantly, the absolute number and percentage of DNT cells were significantly higher in UCBT patients without aGVHD than in those with aGVHD within one year ( F = 4.684, P = 0.039 and F = 5.583, P = 0.026, respectively). In addition, the number of DNT cells in the first month after transplantation decreased significantly with the degree of aGVHD increased, and faster DNT cell reconstitution in the first month after UCBT was an independent protective factor for aGVHD (HR = 0.46, 95% confidence interval [CI]: 0.23-0.93; P = 0.031). Conclusions::Compared to the number of DNT cells in Chinese healthy people, the reconstitution of DNT cells in adults with hematological malignancies after UCBT was slow. In addition, the faster reconstitution of DNT cells in the early stage after transplantation was associated with a lower incidence of aGVHD.

Objective To systematically assess the efficacy and safety of antifibrinolytic drugs for hemostatic efficacy in cardiac surgery for cardiopulmonary diversion in children.Methods A systematic search of PubMed,Embase,and The Cochrane Library was performed to collect all randomized controlled trials(RCTs)using antifibrinolytic drugs in cardiac surgery for cardiopulmonary diversion in children from January 1st,1980 to October 14 th,2023.Meta-analysis was performed using RevMan 5.4 software.Results A total of 20 studies and 23 RCTs were included,with 9 involving peptidase,10 involving tranexamic acid,and 4 involving aminocaproic acid.The result of Meta-analysis showed that compared with the control group,all the experimental groups using antifibrinolytic drugs(peptidase,tranexamic acid,and aminocaproic acid)significantly reduced the amount of hemorrhage and transfusion in the first 24 h postoperatively(P<0.05);however,the difference of the incidence of thrombosis and death in the two groups was not statistically significant(P>0.05).Conclusion Antifibrinolytic drugs have hemostatic effects in cardiac surgery for cardiopulmonary bypass in children.Because of the paucity of evidence from relevant pediatric studies,a large number of comparative trials are needed to assess the safety associated with these drugs and the appropriate dosing regimen.

Objective To compare three surgical treatments for mediastinal mass with myasthenia gravis. Methods Retrospective analysis was performed on the clinical data of 53 patients who underwent extended thymectomy between January 2010 and December 2017 in our hospital. There were 29 males and 24 females, aged 17-73 years. Patients were divided into three groups according to the surgical methods: a group A (video-assisted thoracoscopic surgery with the da Vinci robotic system, n=22), a group B (video-assisted thoracoscopic surgery, n=12) and a group C (median sternotomy, n=19). The gender distribution, age, intraoperative blood loss, operation time, postoperative extubation time, postoperative hospital stay, Osserman classification of myasthenia gravis, postoperative myasthenic remission rate, etc were compared in three groups. Results No perioperative death was observed in 53 patients. One patient in the group C suffered from postoperative myasthenic crisis and improved after active treatment. One patient with video-assisted thoracoscopic surgery was converted to median sternotomy due to the intraoperative injury of the left brachiocephalic vein. Compared with the group B and group C, the group A had shorter operation time, less intraoperative blood loss and drainage on the first postoperative day and fewer days of extubation. Postoperative hospital stay was less in the group A than that in the group C (P<0.05). The postoperative myasthenic remission rate was higher in the group A than that in the other two groups, but there was no statistical difference. Conclusion Because of the robot’s unique minimally invasive advantage, in this study, the outcome of patients with myasthenia gravis treated with Da Vinci robots and thymectomy is better than that of the remaining two groups in terms of perioperative outcomes and myasthenic remission rate. But long-term results and a large of number matching experiments are needed to confirm. However, it is undeniable that robotic surgery must be the future of the minimally invasive surgery.

Objective    To explore the feasibility of robotic sleeve lobectomy and bronchoplasty and to summarize the experience of quality control and technical process management. Methods    From January to December 2018, our hospital completed robotic sleeve lobectomy and bronchoplasty for 5 patients, including the upper right lung lobe in 2 patients, the middle right lung lobe in 1 patient and the lower left lung lobe in 2 patients. There were 3 males and 2 females with an age of 56.6 (39-75) years. The surgical approach was the same as the surgical incision of the robotic lobectomy. During the operation, the lobes were separated, all enlarged mediastinal lymph nodes were cleaned, pulmonary hilum was dissected, pulmonary arteriovenous vessels and bronchi were exposed, and pulmonary vessels were treated. After exposing the main bronchi, the bronchi were cut off at the distal end of the lesion, and the lobes where the lesion was located (including lesions) were excised by sleeve type and the bronchi were continuously sutured with 3-0 Prolene from the back wall for anastomosis. After the anastomosis, no air leakage was found in the expanded lung, and the anastomosis was no longer wrapped. Results    The operation time was 147.4 (100-192) min, including bronchial anastomosis time 17.6 (14-25) min. Intraoperative blood loss was 60.0 (20-100) mL, and 20 (9-37) lymph nodes were dissected. Three patients had squamous cell carcinoma, 1 adenocarcinoma, and 1 neuroendocrine tumor. All patients showed negative results in the freezing pathology of bronchial stump during operation. All patients recovered well after surgery, without perioperative complications, and the anastomosis was smooth. Postoperative hospital stay was 10.8 (7-14) days. The patients were followed up for 6 to 12 months without anastomotic stenosis or other complications. Conclusion    Since the robot system is a special instrument with 3D vision and 7 degrees of freedom for movable joints, the robotic bronchial suture is more flexible and accurate. The robotic sleeve lobectomy and bronchoplasty are safe and feasible.

BACKGROUND: Da Vinci robotic surgery system is widely used in department of thoracic surgery. The aim of this study is to investigate the treatment outcome of stage I non-small cell lung cancer (NSCLC) via da Vinci Surgical System. METHODS: Clinical date of 347 stage I NSCLC patients, who underwent lobectomy and systematic node dissection from Jan. 2012 to Dec. 2017, were reviewed. 134 patients underwent robot-assisted thoracic surgery (RATS) and 213 patients underwent video-assisted thoracic surgery (VATS). To compare perioperative outcome (blood lose, postoperative drainage, drainage time, postoperative hospital stay, number of the LN dissection) and analyze overall survival (OS), disease free survival (DFS) of the two groups and prognostic factors. RESULTS: The RATS group got less blood lose [(49±39 mL for RATS vs (202±239) mL for VATS, P<0.05] and postoperative drainage [Day 1: (248±123) mL for RATS vs (350±213) mL for VATS; Day 2: (288±189) mL for RATS vs (338±189) mL for VATS, P<0.05]. There were no significant difference for drainage time (10±5 for RATS vs 11±8 for VATS, P<0.05) and postoperative hospital stay (13±6 for RATS vs 14±9 for VATS, P<0.05) between the two groups. The RATS group harvested a more number of mean stations (5±2 for RATS vs 4±2 for VATS) and amounts (18±9 for RATS vs 11±8 for VATS) of the lymph nodes, P<0.05. There was no statistically significant difference of OS between RATS and VATS group [1-year OS: 97.3% vs 96%; 3-year OS: 89.8% vs 83.1%; 5-year OS: 87.5 % vs 70.3%; overall survival time (mean): 61 months vs 59 months, P>0.05]; corresponding there had a statistically significant difference of DFS between the two groups [1-year DFS: 93.7% vs 91.3%; 3-year DFS: 87.7% vs 68.4%; 5-year DFS: 87.7% vs 52.5%; disease free survival time (mean): 61 months vs 50 months, P<0.05]. The univariate analysis found that the amounts of the lymph nodes dissection was the prognostic factor for OS and tumor diameter, surgical approach, stations and amounts of the lymph nodes dissection were respectively the prognostic factors for DFS. However, multivariate analysis found that there was not independently factors for OS, but the tumor diameter and surgical approach were independently associated with DFS. CONCLUSIONS There was no significant difference about OS between the two groups, but the RATS got better DFS. RATS got more number of the LN dissection and less blood lose.

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.
