Objective To summarize the anesthesia management and surgical characteristic of modified extended Morrow procedure in treating hypertrophic obstructive cardiomyopathy (HOCM). Methods This retrospective study was conducted in 139 patients (male 83 and female 56)aged from 1 1 to 66 years.They underwent general anesthesia by high dose intravenous fentanyl or sufentanyl combined with propofol infusion and low concentration sevoflurane inhalation.The surgeons chose ap-propriate surgical procedures,including modified extended Morrow procedure,or combined with mi-tral valve repair (replacement)and coronary artery bypass grafting,etc.All patients received intraop-erative transesophageal echocardiography (TEE ) or epicardial echocardiography monitoring. Results There was no death case in hospital.All patients were hemodynamically stable and there were no malignant adverse events such as ventricular fibrillation during perioperative period.70 (50.4%)of patients automatically recovered to cardiac rhythm after aortic unclamping,and 1 1 (7.9%)of patients needed temporary pacemaker due to atrioventricular block.Cardiopulmonary by-pass (CPB)were weaned off successfully without positive inotropic drugs in 103(74.1%)of patients, while others 36(25.9%)needed low dose dopamine,epinephrine or norepinephrine to maintain hemo-dynamics stable.The CPB time was (142 ± 5 1 )min and the time of aortic clamping was (96 ± 37 ) min.Blood protection was used in all patients and 129 (92.8%)of the patients didn’t receive any blood product.Conclusion Modified extended Morrow procedure was a safe and effective surgical pro-cedure for treatment of HOCM.Experienced teamwork was essential to achieve satisfactory clinical results.The key points of anesthesia management were administration of appropriate preoperative drugs,maintaining adequate anesthesia depth,appropriate preload and afterload,heart rate and rhythm.Intraoperative TEE monitoring was the golden standard for guiding and evaluating the effec-tiveness of the surgical procedures.Meanwhile protection of myocardium,lung,brain and blood can help to obtain satisfactory clinical outcomes.

Objective: To evaluate the efifcacy of modiifed extended Morrow procedure on hypertrophic obstructive cardiomyopathy (HOCM) in adolescent patients. Methods: We retrospectively studied 29 consecutive HOCM patients at the age≤21 years who received modiifed extended Morrow procedure in our hospital from 2011 to 2015 for their clinical conditions to assess surgical efifcacy. Echocardiography was performed to compare left atrial size, left ventricular end diastolic diameter, left ventricular ejection fraction, left ventricular outlfow tract peak pressure, ventricular septal thickness, mitral systolic anterior motion and mitral regurgitation grade before and after operation. Moreover, pre-operative and post-operative plasma NT-proBNP levels were determined. Cardiac function was evaluated by New York Heart Association functional class. Results: There were 17 (58.6%) patients received isolated modiifed extended Morrow procedure and 12 patients had concomitant operation including 8 (27.6%) with coronary artery bypass grafting. Compared with pre-operation, the post-operative thickness of ventricular septum decreased from (24.6 ± 6.8) mm to (16.9 ± 7.1) mm, left ventricular outlfow tract gradient decreased from (68.8 ± 15.7) mmHg to (10.7 ± 4.2) mmHg, bothP<0.001; mitral regurgitation degree reduced from (1.7 ± 1.3) to (0.2 ± 0.4),P<0.01; NYHA classification improved from (3.4 ± 0.8) to (1.4 ± 0.5),P<0.01; plasma level of NT-proBNP reduced from (1957.6 ± 392.5) ng/ml to (458.7 ± 161.0) ng/ml,P<0.01. There was no peri-operative death, the survival rates at 12, 24 and 36 months post-operation were 100%, 86.7% and 86.7% respectively. Conclusion: Modiifed extended Morrow procedure has been a safe and effective method for treating adolescent HOCM patients, adequate exposure is the key point to assure surgical efifcacy.

Objective: To summarize the major post-operative complication of modiifed extended Morrow procedure in patients with hypertrophic obstructive cardiomyopathy (HOCM) and to explore the major factors affecting its prognosis. Methods: We retrospectively analyzed 139 consecutive HOCM patients who received the procedure by same surgeon in our hospital from 2012-06 to 2014-07. There were 87 male and 52 female patients with the age of (10-67) years, body weightof (26-105) kg and pre-operative left ventricular outlfow tract peak gradient (LVOTPG) of (84.48 ± 44.75) mmHg. Concomitant operations were performed with known cardiac disease as necessary. Pre- and post-operative echocardiography, ECG and chest X-ray were examined to assess the adequacy of resection and mitral valve structure and function. Results: There was no peri-operative death. 73/139 (53%) patients received simple modiifed expanded Morrow procedure, the other 66 (47%) patients received concomitant surgery including 21 patients with coronary artery bypass grafting, 15 mitral valve plasty, 7 mitral valve replacement, 10 tricuspid valve plasty, 2 aortic valve replacement, 3 modiifed Maze procedure, 2 unblock of right ventricular outlfow tract, 2 sub aortic membrane resection, 1 ventricular aneurysm resection. The mechanical ventilation time was (24.05±36.74) hours, post-operative ICU and in-hospital stays were (2.85±3.18) days and (10.11±4.57) days; the complications included arrhythmia in 108 cases, pleural effusion in 25 cases, secondary intubation in 1 case, tracheotomy in 1 case, hemoifltration in 1 case, intra-aortic balloon pump in 1 case, back into ICU in 3 cases; no pneumothorax, secondary thoracotomy/operation. The post-operative left atrial diameter, LVOTPG, inter-ventricular septal thickness and LVEF were all decreased; mitral valve closed well or with mild regurgitation, systolic anterior motion (SAM) basically disappeared. The major factors for delayed ICU stay included age≥55 years, female, CPB time≥120 min, AOC time≥90 min, the patients combining with arrhythmia and right ventricular dysfunction. Late follow-up presented that the patients were almost without the symptoms, NYHA classiifcation at (I-II), no late death, complication or re-operation. Conclusion: Modified expand Morrow procedure has good surgical and short/late post-operative effects, concomitant operation does not increase the complication and mortality; correction of arrhythmia and improving right ventricular function at peri-operative period are important for treating the relevant patients.

Objective To investigate the blood-saving effect of tranexamic acid in off-pump coronary artery bypass (OPCAB). Methods Two hundred and sixty ASA Ⅰ- Ⅲ and NYHA Ⅰ- Ⅲ patients of both sexes,aged 18-64 yr, with body mass index 16-22 kg/m2 , undergoing OPCAB, were randomly divided into 2 groups (n = 130 each): control group (group C) and tranexamic acid group (group T) . Anesthesia was induced with iv injection of midazolam 0.1 mg/kg, fentanyl 5-10μg/kg and pipecuronium 0.1 mg/kg. The patients were tracheal intubated and mechanically ventilated. PEr CO2 was maintained at 35-45 mm Hg. A bolus of tranexamic acid 1 g was infused intravenously within 30 min after indution followed by continuous infusion at 400 mg/h until the end of operation in group T. While equal volume of normal saline was given in control group. Anesthesia was maintained with inhalation of isoflurane and intermittent iv injection of fentanyl and pipecuronium. Venous blood samples were taken before induction, at the end of operation and at 24 h after operation for determination of Hb, platelet count (P1t), prothrombin time (PT) and international normalized ratio (INR). The volume of chest tube drainage was collected and recorded at 6 and 24 h after operation. The requirement for transfusion of allogeneic red blood cells and fresh frozen plasma was also recorded. Results There was no significant difference in Hb, Plt, PTand INR at each time point between the two groups ( P > 0.05). The requirement for transfusion of allogeneic red blood cells and fresh frozen plasma was significantly reduced in group T as compared with group C ( P < 0.05 or 0.01 ). No deaths and complications occurred during hospital stay in the two groups. Conclusion Tranexamic acid exerts the blood-saving effect in OPCAB.

Objective To investigate the effects of different dialysates on expression of protein kinase C-δ (PKCδ) and apoptosis of U937 cell line. Methods Different dialysates were added into culture fluid with U937 cell line at exponential phase of growth, and groups were divided: fluid A+fluid B group (dialysate A+dialysate B), fluid A+fluid B+rottlerin (PKCδ specific inhibitor)group, fluid A+powder B group (dialysate A+powder B) and fluid A+powder B + rottlerin group. Besides, blank control group and normal control group were established. Cells were harvested 24 h and 48 h after treatment, morphological changes were observed by Hoechst33258 fluorescence staining, cell apoptosis was measured by Annexin-V-FITC/PI double staining, and expression of PKCδ mRNA and protein was detected by RT-PCR and Western blotting, respectively. Results Cell apoptosis significantly increased in fluid A+powder B group, with typical morphology of apoptosis. After treatment for 24 h and 48 h, cell apoptosis rates in fluid A+powder B group were significantly higher than those at corresponding time points in blank control group , normal control group and fluid A+powder B+rottlerin group (P<0.05). Compared with normal control group, blank control group and fluid A+powder B+rottlerin group, the expression of PKCδ mRNA and protein of U937 cells in fluid A+powder B group were significantly increased (P<0.05). There was no significant difference in cell apoptosis rates and expression of PKCδ mRNA and protein between fluid A+fluid B group and blank control group, normal control group and fluid A+fluid B+rottlerin group (P>0.05). Conclusion Fluid A+powder B can significantly increase apoptosis of U937 cell line, the mechanism of which may be associated with the up-regulation of expression of PKCδ. Compared with fluid A+powder B, fluid A+fluid B is superior in reducing apoptosis of peripheral blood monouclear cells.

Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.

Objective To summarize the perioperative management strategies and early results of modified Morrow expanded operation and coronary artery bypass grafting (CABG) in patients with hypertrophic obstructive cardiomyopathy (HOCM) and coronary atherosclerotic heart disease. Methods Between January 2012 and December 2017, in the Second Inpatient Department of Fuwai Hospital, 32 patients (20 females and 12 males) underwent modified expanded Morrow operation and CABG. The median age was 53.7±8.7 years (interquartile range 37 to 67 years). Preoperative chest distress symptom was found in 24 patients, chest pain symptom was found in 14 patients, history of syncope in 6 patients. Cardiac echocardiography, electrocardiogram, chest X-ray, magnectic resonance imaging (MRI) were performed routinely after operation and follow-up to analyze structure and function of heart and mitral valve. Results All patients underwent modified and expanded Morrow combined with CABG. The preoperative left ventricular outflow tract peak pressure difference (LVOTG) was 40 to 152 (79.6±28.7) mm Hg. Four patients underwent myocardial bridge releasing in the same period, mitral valve replacement in 2 patients, mitral valve angioplasty in 3 patients, Maze operation in 2 patients and tricuspid valveoplasty in 3 patients. There was no hospital mortality. CABG surgery in patients with branches included anterior descending artery in 26 patients, diagonal branch in 16 patients, left circumflex in 8 patients, right coronary artery in 11 patients. There were 15 patients with one coronary artery (CA) bypass graft, 5 patients with two CA bypass grafts, and 12 patients with 3 CA bypass grafts. The average of CA bypass grafts was 1.9±0.6. The postoperative ICU time ranged from 1–13 (4.1±2.8) days and postoperative hospital stay ranged from 7 to 30 (12.6±5.5) days. No severe postoperative complications were found and 1 patient had postoperative incision healing. The postoperative new arrhythmia included left bundle branch block in 6 patients. Compared with the preoperative values, postoperative left ventricular outflow tract peak pressure (79.6±28.7 mm Hg vs. 10.8±5.9 mm Hg, P<0.001), interventricular septum thickness (1.9±0.4 cmvs. 1.3±0.5 cm, P<0.001) were decreased obviously. Mitral valve closure is good or only mild reflux, mitral valve forward movement (SAM sign) disappeared. The patients were followed up for 6-68 months, with an average of 38.8±20.6 months. All patients were followed up with symptoms disappeared or only mild symptoms. NYHA classification decreased Ⅰ to Ⅱ grade after surgery, without long-term mortality, complications or reoperation. Conclusion For patients with hypertrophic obstructive cardiomyopathy with coronary atherosclerotic heart disease, the application of improved expand morrow operation at the same time undergoing coronary artery bypass grafting is safe. It can significantly improve patients' survival and reduce symptoms, play a synergistic effect, and do not increase the patient's surgical complications.
