ObjectiveTo detect the expression of human transforming growth factor β1 (hTGF-β1) gene mediated by adenovirus (Ad) in hamstring tendon after anterior cruciate ligament (ACL) reconstruction in rabbits. MethodsAd-hTGF-β1 and Ad-green fluorescent protein (GFP) were diluted to 5×108 PFU/mL with DMEM. Forty-eight New Zealand white rabbits were divided into 3 groups randomly (n=16) for ACL reconstruction with hamstring tendon autograft. Hamstring tendon was cultured and transfected with Ad-hTGF-β1 (group A) and Ad-GFP (group B) for 12 hours before ACL reconstruction, and was cultured with DMEM in group C. After 12 hours of transfection, green fluorescence was observed in groups A and B under fluorescence microscopy. At 2, 4, 6, and 8 weeks after operation, the hamstring tendon was harvested to detect the mRNA and protein expressions of hTGF-β1 by real time fluorescence quantitative PCR and Western blot. ResultsGreen fluorescence was observed after 12 hours of transfection in groups A and B. TGF-β1 protein level reached (221.0±12.2) ng/mL at 12 hours in group A. The hTGF-β1 mRNA expression could be detected in group A, but it could not be detected in group B and group C. The mRNA expression levels of hTGF-β1 were 1.004±0.072 at 2 weeks, 0.785±0.038 at 4 weeks, 0.469±0.053 at 6 weeks, and 0.172±0.021 at 8 weeks in group A, showing significant difference (P<0.05). Western blot results showed weakly positive band in groups B and C; the protein expression of TGF-β1 in group A was significantly higher than that in groups B and C (P<0.05), but no significant difference was found between groups B and C P>0.05). The protein expression of TGF-β1 gradually reduced with time, showing significant difference between different time points (P<0.05). ConclusionAd-hTGF-β1 can transfect the hamstring tendon successfully, and it can effectively express for a long time after ACL reconstruction.
ObjectiveTo analyze whether hypernatremia within 48 hours after cardiac surgery will increase the incidence of delirium which developed 48 hours later after surgery (late-onset delirium).MethodsWe conducted a retrospective analysis of 3 365 patients, including 1 918 males and 1 447 females, aged 18-94 ( 60.53±11.50) years, who were admitted to the Department of Cardiothoracic and Vascular Surgery of Nanjing First Hospital and underwent cardiac surgery from May 2016 to May 2019.ResultsA total of 155 patients developed late-onset delirium, accounting for 4.61%. The incidence of late-onset delirium in patients with hypernatremia was 9.77%, the incidence of late onset delirium in patients without hypernatremia was 3.45%, and the difference was statistically different (P<0.001). The odds ratio (OR) of hypernatremia was 3.028 (95% confidence interval: 2.155-4.224, P<0.001). The OR adjusted for other risk factors including elderly patients, previous history of cerebrovascular disease, operation time, cardiopulmonary bypass time, lactate, hemoglobin≥100 g/L, prolonged mechanical ventilation, left ventricular systolic function, use of epinephrine, use of norepinephrine was 1.524 (95% confidence interval: 1.031-2.231, P=0.032).ConclusionHypernatremia within 48 hours after cardiac surgery may increase the risk of delirium in later stages.
Objective To explore the therapeutic effect of mild hypothermia on the inflammatory response, organ function and outcome in perioperative patients with acute Stanford type A aortic dissection (AAAD). Methods From February 2017 to February 2018, 56 patients with AAAD admitted in our department were enrolled and randomly allocated into two groups including a control group and an experimental group. After deep hypothermia circulatory arrest during operation, in the control group (n=28), the patients were rewarmed to normal body temperatures (36 to 37 centigrade degree), and which would be maintained for 24 hours after operation. While in the experimental group (n=28), the patients were rewarmed to mild hypothermia (34 to 35 centigrade degree), and the rest steps were the same to the control group. The thoracic drainage volume and the incidence of shivering at the first 24 hours after operation, inflammatory indicators and organ function during perioperation, and outcomes were compared between the two groups. There were 20 males and 8 females at age of 51.5±8.7 years in the control group, 24 males and 4 females at age of 53.3±11.2 years in the experimental group.Results There was no obvious difference in the basic information and operation information in patients between the two groups. Compared to the control group, at the 24th hour after operation, the level of peripheral blood matrix metalloproteinases (MMPs) was lower than that in the experimental group (P=0.008). In the experimental group, after operation, the awakening time was much shorter (P=0.008), the incidence of bloodstream infection was much lower (P=0.019). While the incidence of delirium, acute kidney injury (AKI), hepatic insufficiency, mechanical ventilation duration, intensive care unit (ICU) stays, or hospital mortality rate showed no statistical difference. And at the first 24 hours after operation, there was no difference in the thoracic drainage volume between the two groups, and no patient suffered from shivering. Conclusion The mild hypothermia therapy is able to shorten the awakening time and reduce the incidence of bloodstream infection after operation in the patients with AAAD, and does not cause the increase of thoracic drainage volume or shivering.
ObjectiveTo evaluate whether long frozen elephant trunk (FET) increases the risk of spinal cord injury in patients with acute type A aortic dissection.MethodsFrom 2018 to 2019, 172 patients with acute type A aortic dissection were treated in Guangdong Provincial People’s Hospital. They were divided into two groups according to the length of FET: patients treated with stents of 100 mm in length were enrolled into a short FET group, and those with stents of 150 mm in length into a long FET group. There were 124 patients in the short FET group, including 108 (87.1%) males and 16 (12.9%) females with a mean age of 51.8±7.9 years. There were 48 patients in the long FET group, including 44 (91.7%) males and 4 (8.3%) females with a mean age of 50.6±9.7 years. The clinical data and prognosis of the patients were analyzed.ResultsThe mean distal stent graft was at the level of T 8.5±0.7 in the long FET group, and at the level of T 6.8±0.6 in the short FET group (P=0.001). Sixteen patients died after operation in the two groups, including 13 (10.5%) in the short FET group and 3 (6.2%) in the long FET group (P=0.561). There were 7 patients of spinal cord injury in the two groups, including 6 (4.8%) in the short FET group and 1 (2.2%) in the long FET group (P=0.675). There was no statistical difference in other complications between the two groups. The follow-up time was 16.7 (1-30) months. During the follow-up, 2 patients died in the long FET group and 5 died in the short FET group. No new spinal cord injury or distal reintervention occurred during the follow-up.ConclusionLong FET does not increase the incidence of spinal cord injury in patients with acute type A aortic dissection.
Objective To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears. Methods A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient’s satisfactions were calculated at last follow-up. Results All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation (P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation (P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months (P<0.05). However, there was no significant difference (P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation (P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%). Conclusion Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.
Objective To explore the early effectiveness of arthroscopic tri-anchor double-pulley suture-bridge in treatment of medium-size supraspinatus tendon tears. Methods Between December 2020 and January 2023, 40 patients with medium-size supraspinatus tendon tears were treated with arthroscopic tri-anchor double-pulley suture-bridge. There were 18 males and 22 females, with an average age of 62.6 years (mean, 45-73 years). Among them, 17 patients had trauma history. The main clinical symptom was shoulder pain with hug resistance test (+). The interval from symptom onset to operation was 10.7 months on average (range, 3-36 months). Visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up. Results All incisions healed by first intention, no complications such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.2 months). At 12 months after operation, VAS score, UCLA score, and ASES score significantly improved when compared with the preoperative scores (P<0.05). At 3 and 12 months after operation, the ROM of external rotation significantly improved when compared with preoperative one (P<0.05), and further improved at 12 months after operation (P<0.05). However, the ROMs of abduction and forward flexion did not improve at 3 months after operation when compared with those before operation (P>0.05), but significantly improved at 12 months after operation (P<0.05). Twenty-six patients underwent MRI at 3-6 months, of which 23 patients possessed intact structural integrity, good tendon tension, and tendon healing; 3 patients underwent tendon re-tear. The self-rated satisfaction rate was 92.5% at last follow-up. Conclusion Arthroscopic tri-anchor double-pulley suture-bridge in treatment of medium-size supraspinatus tendon tears can maximize the tendon-bone contact area, obtain satisfied early effectiveness with high satisfaction rate and low incidence of tendon re-tear. However, the function of abduction is limited at 3 months after operation, and patients need to adhere to rehabilitation training to further improve the joint activity.
