ABSTRACT
ObjectiveTo study the possible mechanism of Chaihu Shugan Powder （柴胡疏肝散， CSP） in the treatment of functional dyspepsia （FD）. MethodsTwenty-four SD rats were randomly divided into a normal group， a model group， a CSP group and a probiotic group， with six rats in each group.The tail-clamping provocation method was used in all groups except for the normal group to replicate the FD rat model. Simultaneously， the normal group and the model group were given 10 ml/（kg·d） of saline by gavage， while the CSP group and the probiotic group were given 9.6 g/（kg·d） of CSP aqueous decoction and 0.945 g/（kg·d） of probiotic aqueous solution by gavage， respectively， twice daily for four weeks. After four weeks， the gastric emptying and small intestinal propulsion rates were detected in each group of rats. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in the gastric sinusoids and duodenum of the rats. The changes in the intestinal flora were analyzed by 16s rDNA high-throughput gene sequencing， and the expressions of the duodenal zona occludin 1 （ZO-1） and Occludin were detected by immunohistochemistry and western blotting. Pearson correlation analysis was performed on intestinal flora and ZO-1 and Occludin protein expression. ResultsThe gastric antrum tissue structure was clear in all groups， and the gland structure was regular， with smooth gastric tissue mucosa and no pathological changes such as erosion and ulcer. Compared to those in the normal group， the intestinal villi in the duodenal tissue in the model group were significantly reduced or atrophied， and the goblet cells were arranged in disorder， with eosinophilic infiltration； the gastric emptying rate and small intestinal propulsion rate， as well as ZO-1 and Occludin protein expression in duodenal tissue significantly decreased （P＜0.01）. Compared to those in the model group， the duodenal tissue structure was clear， and the length intestinal villi was longer， with goblet cells neatly arranged in the CSP group and the probiotic group； no obvious eosinophil infiltration was found， and the gastric emptying rate and small intestinal propulsion rate as well as ZO-1 and Occludin protein expression significantly increased in the CSP group； a small amount of eosinophil infiltration was found， and the gastric emptying rate and Occludin protein expression significantly increased in the probiotic group （P＜0.05 or P＜0.01）. Beta diversity analysis of intestinal flora showed that the overall structure of intestinal flora in the model group changed significantly compared to that in the normal group （P＜0.01）. The overall structure of the intestinal flora in the CSP group and the probiotic group was closer to the normal group than the model group. Species composition analysis showed that the relative abundance of the Firmicutes decreased， while the relative abundance of the Bacteroidetes and norank_f_Muribaculaceae increased， and the Bacteroidetes/Firmicutes value increased in the model group than those in the normal group （P＜0.05 or P＜0.01）. Compared to those in the model group， the relative abundance of the Firmicutes increased， while the relative abundance of the Bacteroidetes and norank_f_Muribaculaceae， as well as the Bacteroidetes/Firmicutes value decreased in the CSP group and the probiotic group （P＜0.05 or P＜0.01）. There was no statistically significant difference in each indicator between the probiotic group and the CSP group （P＞0.05）. Pearson correlation analysis showed that at the phylum level， Firmicutes was positively correlated with ZO-1 （r=0.610， P=0.016） and Occludin （r=0.694， P=0.004） protein expression. Bacteroidetes was negatively correlated with ZO-1 （r=-0.557， P=0.031） and Occludin （r=-0.662， P=0.007） protein expression. At the genus level， norank_f_Muribaculaceae was negatively correlated with ZO-1 （r=-0.727， P=0.002） and Occludin （r=-0.760，P=0.001） protein expression. ConclusionCSP can restore the structure of intestinal flora， regulate the abundance levels of Firmicutes， Bacteroidetes and norank_f_Muribaculaceae， up-regulate ZO-1 and Occludin proteins， and thus repairing the duodenal mucosal barrier， and playing a therapeutic role in FD rats.
ABSTRACT
@#Objective To evaluate the clinical outcome of valved homograft conduits (VHC) used for right ventricular outflow tract (RVOT) reconstruction in Fuwai Hospital in recent 13 years, and explore the factors influencing the long-term durability of VHC. Methods Clinical data of patients using VHC for RVOT reconstruction in Fuwai Hospital from November 2007 to October 2020 were retrospectively analyzed. The Kaplan-Meier survival curve was used to evaluate survival, VHC reintervention and VHC dysfunction. Cox proportional risk regression model was used to analyze the risk factors for VHC dysfunction. Results Finally 251 patients were enrolled, including 145 males and 106 females. The median age at surgery was 6.0 (0.3-67.0) years. Early death occurred in 5 (2.0%) patients. The follow-up was available for 239 (95.2%) patients, with the follow-up time of 0.3-160.0 (61.3±45.4) months. Five patients died during the follow-up, and the 1-year, 6-year, and 13-year survival rates were 96.6%, 95.5% and 95.5%, respectively. Eight patients received VHC reintervention during the follow-up, and freedom rates from VHC reintervention were 100.0%, 97.1% and 82.4% at 1 year, 6 years and 13 years, respectively. A total of 226 patients were followed up by echocardiography after discharge, with the follow-up time of 0.2-138.0 (48.5±40.5) months. During the follow-up, 46 (20.4%) patients developed VHC dysfunction, and freedom rates from VHC dysfunction at 1 year, 5 years, and 10 years were 92.6%, 79.6% and 59.3%, respectively. Univariate Cox regression analysis showed that age<6 years and VHC diameter<19 mm were risk factors for VHC dysfunction (P=0.029, 0.026), but multivariate regression analysis only indicated that age<6 years was an independent risk factor for VHC dysfunction (P=0.034). Conclusion The early and late outcomes of VHC used for RVOT reconstruction are satisfactory, and the long-term durability of VHC is also optimal. In addition, age<6 years is an independent risk factor for VHC dysfunction.
ABSTRACT
@#Objective To compare the long-term durability of valved homograft conduit (VHC) in patients with Ross and non-Ross right ventricular outflow tract (RVOT) reconstruction. Methods Patients who underwent RVOT reconstruction using VHC in Fuwai Hospital from January 2008 to October 2020 were retrospectively included. Patients who received Ross RVOT reconstruction were allocated to a Ross group and patients who received non-Ross RVOT reconstruction were allocated to a non-Ross group. The survival and reintervention-free rates of the two groups were evaluated with the Kaplan-Meier survival curve and log-rank test. The propensity score matching analysis was performed on the patients who completed ultrasound follow-up in the two groups, and the VHC dysfunction-free rate was compared between the two groups. Results A total of 243 patients were enrolled, including 142 males and 101 females, with a median age of 6 years (4 months to 56 years). There were 77 patients in the ROSS group and 166 patients (168 operations) in the non-ROSS group. The cardiopulmonary bypass time in the Ross group was shorter than that in the non-Ross group (175.4±45.6 min vs. 200.1±83.5 min, P=0.003). Five patients in the non-Ross group died early after the operation. The follow-up was available in 231 patients (93.1%), with the average follow-up time of 61.7±44.4 months. During the follow-up, 5 patients in the non-Ross group died. The 12-year survival rate was 100.0% in the Ross group and 93.2% in the non-Ross group (log-rank, P=0.026). In addition, 1 patient in the Ross group and 7 patients in the non-Ross group received VHC reintervention. There was no significant difference in the reintervention-free rate between the two groups (log-rank, P=0.096). Among the 73 patients in the Ross group and 147 patients in non-Ross group who were followed up by ultrasound after discharge, 45 patients (20.5%) developed VHC dysfunction. Before matching, the long-term durability of VHC in the Ross group was better than that in non-Ross group (10-year VHC dysfunction-free rate: 66.6% vs. 37.1%, log-rank, P=0.025). After the propensity score matching, 64 patients included in each group, and there was no statistical difference in the long-term durability of VHC between the two groups (10-year VHC dysfunction-free rate: 76.3% vs. 43.0%, log-rank, P=0.065). In the subgroup analysis, the 10-year VHC dysfunction-free rate in the Ross group was higher than that in the non-Ross group (71.0% vs. 20.0%, log-rank, P=0.032) among patients aged<6 years at surgery. However, there was no significant difference in the 10-year VHC dysfunction-free rate between the two groups (53.7% vs. 56.7%, log-rank, P=0.218) among patients aged ≥6 years at surgery. Conclusion After the propensity score matching analysis, the long-term durability of VHC has no significant difference between the Ross group and non-Ross group. The long-term durability of VHC after Ross surgery is superior to that of non-Ross surgery in patients aged<6 years at surgery.
ABSTRACT
@#Objective To evaluate the safety and efficacy of peripheral cannulation for cardiopulmonary bypass (CPB) in patients with reoperation of congenital heart disease. Methods The perioperative data of patients with congenital heart disease who underwent reoperation in Fuwai Hospital from 2019 to 2020 were retrospectively collected. They were divided into two groups according to the cannulation methods: a central group and a peripheral group. The prognosis of the patients was analyzed. Results A total of 80 patients were collected, including 43 patients in the central group, and 37 pateints in the peripheral group. In the central group, the median age was 18 (14, 32) years, and 21 patients were male. The median age of the peripheral group was 16 (10, 27 ) years, and 18 patients were male. The CPB time in the peripheral group was 201 (164, 230) min, which was longer than that in the central group [143 (97, 188 ) min, P<0.001]. The lactate after CPB in the peripheral group was statistically higher than that in the central group [2 (1, 2 ) mmol/L vs. 1 (1, 1) mmol/L, P=0.002]. The dosage of albumin use during CPB in the peripheral group was statistically higher than that in the central group [10 (0, 20) g vs. 0 (0, 0) g, P=0.004]. There was no statistical difference in the postoperative dosage of red blood cells use [0 (0, 2) U vs. 0 (0, 0) U, P=0.117], mechanical ventilation time [14 (11, 19) h vs. 13 (10, 15) h, P=0.296], ICU stay time [43 (23, 80) h vs. 40 (20, 67) h, P=0.237] or postoperative hospital stay time [10 (7, 12) d vs. 8 (7, 10) d, P=778] between the two groups. Conclusion It’s safe and efficient to establish CPB through peripheral cannulation in patients with complex congenital heart disease undergoing reoperation.
ABSTRACT
@#Objective To summarize the surgical experience of infants with transposition of the great arteries (TGA) and intramural coronary artery (IMCA) in our center, and analyze the early and mid-term outcomes. Methods We retrospectively analyzed the clinical data of 384 infants with TGA undergoing arterial switch operation (ASO) from June 2010 to December 2018 at Fuwai Hospital. According to operative records, 21 (5.5%) infants had IMCA, among whom 20 were males, with a median age of 33 (9-319) d. Coronary transfer using double coronary buttons with unroofed intramural course was performed in all 21 infants. Results There was no statistical difference in the early mortality after ASO between infants with IMCA and infants with normal coronary anatomy (9.5% vs. 3.0%, P=0.15). In the IMCA group, 2 dead patients presented inadequate coronary artery perfusion after first aortic unclamping. In addition, 1 patient underwent extracorporeal membrane pulmonary support for myocardial dysfunction. The follow-up was available for all 19 survivors, with an average follow-up time of 29.0-120.0 (74.8±27.3) months. During the follow-up, all patients had no obvious symptoms, death, reoperation, or coronary complications. One patient developed moderate pulmonary valve regurgitation and another patient developed distal stenosis of the right pulmonary artery. Conclusion For infants with TGA and IMCA, coronary transfer using double coronary buttons with unroofed intramural course is a safe and reliable technique, with satisfactory early and mid-term outcomes.
ABSTRACT
@#Objective To evaluate mid-term outcomes of pulmonary valve replacement surgery after repair of tetralogy of Fallot. Methods A total of 73 patients with repaired tetralogy of Fallot who underwent pulmonary valve replacement surgery in our hospital from January 2010 to January 2020 were enrolled, including 42 males and 31 females. The median age was 3.9 (0.2-42.8) years at initial repair and 20.0 (2.0-50.0) years at pulmonary valve replacement. The clinical data of the patients were recorded and analyzed. Results There was no death in postoperative 30 d. The average follow-up time was 35.6±28.5 months, and no death occurred during the follow-up. One patient underwent a second reintervention after initial pulmonary valve replacement. The 1- and 5-year survival rates were both 100.0%, the 1- and 5-year reintervention-free rates were both 100.0%, and the 1- and 5-year valve failure-free rates were 100.0% and 67.1%. There was no significant difference in valve failure-free rates between different age groups (P=0.49) and different type of valve groups (P=0.74). The right (P=0.006) and left (P=0.002) ventricular ejection fractions were significantly improved, and the QRS duration was shortened after pulmonary valve replacement (P=0.006). Conclusion Mid-term outcomes of surgical pulmonary valve replacement were satisfactory in patients with repaired tetralogy of Fallot, while the long-term effects should be further emphasized in clinical practice.
ABSTRACT
@#Objective To analyze the Ebstein anomaly's reoperative strategy and mid- to long-term results. Methods We retrospectively reviewed the clinical data of 23 patients who diagnosed with Ebstein anomaly and underwent reoperation for tricuspid valve insufficiency between July 2002 and July 2017 in Fuwai Hospital. There were 9 (39.1%) males and 14 (60.9%) females, with a median age of 28.0 (19.0, 45.0) years. Results Among the 23 patients, 8 (34.8%) underwent tricuspid valvuloplasty and 15 (65.2%) underwent tricuspid valve replacement. The rate of valvuloplasty was 16.7% before 2012, and 54.5% after 2012 (P=0.089) as Cone reconstruction procedure was used. In the valvuloplasty cohort, 3 (37.5%) patients were treated with Danielson or Carpentier technique, and 5 (62.5%) patients were treated with Cone reconstruction procedure. There was no operation-related death. Early complications occurred in 3 (37.5%) patients. The median follow-up was 6.9 years (range, 3.0-15.1 years), and no adverse cardiac events occurred. In the patients with valve replacement, 7 (46.7%) received mechanical prosthesis and 8 (53.3%) received bio-prosthesis. There was no operation-related death. And early complications were observed in 3 (20.0%) patients. The median follow-up was 6.5 years (range, 2.5-15.3 years). One (6.3%) patient died and 4 (26.7%) had long-term complications during the follow-up period. Conclusion The mid- to long-term outcomes are convincing in patients who undergo the second operation due to recurrent tricuspid regurgitation of Ebstein anomaly. A low incidence of reoperation is observed. Cone reconstruction procedure provides possibilities of second tricuspid valvuloplasty, and this technique can reduce the rate of tricuspid valve replacement in the second operation. Tricuspid valve replacement is still an alternative method for the treatment of recurrent tricuspid regurgitation in patients with Ebstein anomaly. The bioprosthetic prosthesis may be a better choice than mechanical prosthesis.

Objective To study the mid-and long-term outcomes and prognostic risk factors of mitral valve replacement (MVR) in children.Methods Retrospectively studied the cases(＜ 14 years) receiving MVR between July 2003 and March 2014 in our hospital,and recorded the gender,age,operation related data and the results of echocardiography,electrocardiogram and chest X-ray in the out-patient department.Results A total of 48 patients were followed up.Age was 8 months 15 days-13 years 9 months and 22 days,the average was (9.5 ± 3.9) years.24 cases were original operations,others were second operations.43 mechanical valves were used,as well as 5 tissue valves.The mortality was 8.3 ％ and the incidence of complications was 25.0％ during the hospitalization or within 30 days after the operations.Follow-up time was 4.7-150.7 months,the average was(62.0 ± 42.3) months.The long-term mortality was 9.1％,and the incidence of complications was 9.4％.Follow-up of left ventricular ejection fraction was 0.30-0.77,the average was 0.61 ±0.08.There was no redo-MVR or implantation of pace maker.The survival rates of 1 year,5 years and 10 years were (89.5 ± 4.5) ％、(83.0 ± 6.1) ％、(77.8 ±7.6)％,respectively.Children younger than 5 years was the risk factor for perioperative mortality or complications (OR =8.47,95％ CI:1.36-52.61).Children with perioperative complications was the risk factor for long-term mortality or complications(OR =9.97,95％ CI:1.39-71.76).Conclusion The results of children with MVR were satisfactory.To perform MVR in children older than 5 years if possible and to reduce the incidence of perioperative complications could improve the prognosis.
ABSTRACT
Objective: To evaluate mid-term outcomes for the application of homograft valve conduits in right ventricular outlfow reconstruction in patients with congenital heart disease. Methods: We retrospectively studied 122 patients who received right ventricular outlfow reconstruction by homograft valve conduits application in our hospital from 2007-10 to 2014-07. The patients were divided into different sets of groups, by surgical procedure: Ross group,n=38 and Non-Ross group,n=84; by median age: ≤6 years group,n=61 and >6 years group, n=61; by the type of valve conduits: Aortic homograft group,n=21 and Pulmonary homograft group,n=101; by the diameter of conduits: ≤19 mm group,n=31 and >19 mm group,n=91. The relationships between pre-operative conditions, different types of conduits and diameters to the prognosis were analyzed; the post-operative death, re-operation, free homograft valve conduits failure rates were followed-up in all patients. Results: The average follow-up time was (35.4 ± 22.2) months and 2/122 (1.6%) patients died during that period, the overall free conduits failure rates at 1, 5 and 7 years post-operation were 94.2%, 81.2% and 75.4% respectively. The free conduits failure rates in Pulmonary homograft group at 1, 5, 7 years post-operation were 96.2%, 86.1%,79.9% and in Aortic homograft group were 80.0%, 59.7%, 59.7% respectively,P=0.011; in Ross group were 96.4%, 89.0%, 89.0% and in Non-Ross group were 91.3%, 78.3%, 67.1% respectively,P=0.045. While the age, conduits diameter, cyanosis and re-operation had no statistical meaning to free conduits failure rates, allP>0.05. Conclusion: Application of homograft valve conduits had good mid-term outcomes in right ventricular outflow reconstruction in patients with congenital heart disease, while the long-term effects should be further emphasized in clinical practice.
ABSTRACT
Occult breast cancer is a rare disease with the primary symptom of enlarged ipsilateral axillary lymph node. At present,it is still difficult to diagnose occult breast cancer. The diagnosis is based on the core needle biopsy and following immunohistochemical staining for the enlarged lymph nodes. If the results support,the diagnosis can be confirmed after the exclusion of other primary tumors. The standard treatment of occult breast cancer is still the mastectomy and axillary lymph node dissection. Neoadjuvant chemotherapy is an independent factor affecting the prognosis,which is also recommended before the oper-ation. Chemotherapy,radiotherapy and endocrine therapy could be chosen based on immunohistochemical results after surgical treatment. The prognosis of occult breast cancer is similar to the other types of breast cancer at the same staging.

Objective To summarize 500 cases of surgical experience in restoration of adult congenital heart disease ( ACHD) treatment and early postoperative.Methods During January 2012 to December 2014 in Fuwai Hospital, 500 cases of ACHD treated by operation were chosen to collect the clinical data .We divided the groups according to whether the case was a complex malformation and whether the case had an ICU retention time is more than the 5 days.Results The average age was 35, the average weight was 59 kg.The operation average cardiopulmonary bypass(CPB) time was 102min.The average ICU treatment time was 2 days, the average duration of mechanical ventilation was 23 hours, 3 early deaths occurred.The complex malformation group had younger age and less weight than the simple malformation group , the complex malformation group had longer time of cardiopulmonary bypass time, aortic cross clamping time, mechanical ventilation time and ICU treatment time, had higher rate of complication and blood transfusion peri-operative period than the simple malformation group.(P<0.05) The group of ICU retention time less than 5 days had higher rate of the male proportion, had younger age and less weigh, had longer time of cardiopulmonary bypass time , mechanical ventilation time and ICU treatment time , had higher rate of complication and blood transfusion peri-operative period than the control group(P <0.01).Conclusion Although ACHD patients have long medical history and complicated pathological and physiological changes , when they get proper surgical operation and periopera-tive treatment, they should obtain satisfied effect.Professional medical team or organization service for the ACHD patient is very important and urgent to build.
ABSTRACT
Objective To analyze the distribution characteristics and influencing factors of brachial-ankle pulse wave velocity (baPWV) in elderly population in order to direct the early diagnosis and prevention of arteriosclerosis in the elderly.Methods A total of 927 cases of elderly residents were randomly selected from 19 villages in Shengze area,Jiangsu Province.The indexes such as age,gender,height,weight,waist circumference,hip circumference and blood pressure were collected through standardized questionnaire and physical examination.The biochemical indicators including serum bilirubin,creatinine,uric acid,fasting blood glucose and blood lipids were measured,and baPWV was tested by automatic arteriosclerosis measurement system.Results The differences in age,systolic blood pressure,heart rate,serum bilirubin,creatinine,uric acid,triglycerides levels and baPWV were statistically significant between the male and female (all P＜0.05).BaPWV rised with the increase of age.Overall,baPWV was faster in the female than in male (P＜0.01).Blood pressure (r=0.36,0.59,P＜0.001),age (r=0.26,0.30,P＜0.001) and heart rate (r=0.30,0.33,P＜ 0.001) were correlated with baPWV,while uric acid had a correlation with baPWV (r=0.12,0.21,P＜0.01).A correlation was found between total cholesterol and baPWV (r=0.09,0.11,P＜0.05) Multi-variable linear stepwise regression analysis showed that systolic blood pressure,heart rate and age were the influencing factors for baPWV,of which systolic blood pressure had the greatest influence on baPWV (β＞0.5,P＜0.001).Conclusions With the increase of age,the baPWV shows rising trend.The monitor of baPWV may be useful in the elderly,especially in females.Blood pressure control,especially the control of systolic blood pressure can slow the progression of atherosclerosis.
ABSTRACT
<p><b>OBJECTIVE</b>We followed up all the patients underwent pulmonary artery banding (PAB) with or without the second stage double switch (DS) operation to compare the midterm outcomes between the DS and the prolonged palliative PAB.</p><p><b>METHODS</b>From January 2005 to June 2012, 40 consecutive patients diagnosed with congenital corrected transposition of the great arteries (cc-TGA) with morphologically involuted left ventricle were included in this retrospective cohort study. Every patient underwent the first stage PAB. The second stage DS was performed in 15 patients (DS group) and the palliative PAB was prolonged in the other 25 patients (PAB group). The median age at PAB was 3.1 years (range, 3 months to 8 years), weight was 11.5 kg (range, 5.0 kg to 21.5 kg). The patients were followed up after surgery.</p><p><b>RESULTS</b>Follow-up time was (3.4 ± 0.7) years. Overall mortality was 33.3% (5/15) in DS group and 4.0% (1/25) in PAB group (P < 0.05). The ratio of NYHAI-II was 80.0% (8/10) in DS group and 95.9% (23/24) in PAB group (P < 0.05) and the mean left ventricle ejection fraction was (51.4 ± 9.6)% in DS group and (61.0 ± 6.4)% in PAB group(P < 0.01) during follow up. There was no PAB related cyanosis or ventricular dysfunction and the trans-banding pressure gradient was (46.9 ± 21.5)mmHg (1 mmHg = 0.133 kPa) in PAB group. Echocardiography examination revealed moderate to large aortic regurgitation in 3 patients and severe post-double switch operative arrhythmias was found in 2 patients in DS group. The age at PAB (HR = 13.30, 95%CI:6.28-14.02, P < 0.05) and left ventricle dysfunction (HR = 4.77, 95%CI:2.71-8.68, P < 0.05) were identified as the risk factors for mortality after DS.</p><p><b>CONCLUSION</b>Compared to the DS, the prolonged palliative PAB procedure is associated with lower mortality and better cardiac function post operation.</p>

Objective To study the strategy of expanding standard donor heart application and to analyze the clinical effect on applying expanding standard donor heart in heart transplantation.Methods 146 patients received heart transplantation in Fuwai Hospital Bering from June 2004 to February 2009.Expanding standard donor heart was defined as prolonged ischemic time over 6 h,advanced age up to 40,and blood type ABO mismathched.Blood type examination and PRA test were done before operation.The donor heart was preserved by sequential perfusion with cold St.Thomas and HTK solution.The patients were divided into groups according to different oversize body weight,ischemic time,and donor age Results There were 11 deaths after operation.Ischernic time of donor heart was 262.1±120.8 min,and that of 21 donors was over 360 min(the longest one was 605 min).There was no significant diffeFence in recipient properties before transplantation.and also there was no significant difference in mortality,heart function,heart rejection,and main morbidity after transplantation and during follow-up.Conclusion These data support continued aggressive utilization of expanding standard donor hearts in heart transplantation.Our experience demonstrates thatproperly expanding standard cardiac allografts application has no effects on the short- and long-term clinical outcome following heart transplantation.
ABSTRACT
Objective To summarize risk factors for clinical outcomes in heart transplantation patients, evaluate the characters of Chinese patients by comparing with international data, and introduce new clinical strategies. Methods We performed 200 heart transplantations from Jun. 2004 to May 2010. The clinical information was recorded and all patients were followed up. By analyzing 160 patients with a follow-up period of more than one year, we summarized clinical outcomes and risk factors of early and late results of heart transplant patients. Results Of 160 patients, 8. 1 % received postoperative extracorporeal membrane oxygenation (ECMO) support and 10% continuous renal replacement therapy. In 550 cases/times of endomyocardial biopsies, the incidence of rejection with grades more than Ⅱ (concluding grade Ⅱ ) was 14. 9%. In-hospital mortality was 3. 8%. Smoking,preoperative diastolic pulmonary arterial pressure, PAWP, total serum protein level and albumin level were risk factors of peri-operative mortality, and preoperative diastolic pulmonary arterial pressure,primary heart diseases, pulmonary hypertension and implantations of ICD, MCS and ECMO were risk factors of late mortality. Postoperatively, 1-, 3- and 5-year survival rate was 94. 4%, 91.9% and 88. 8%, respectively. Compared with UNOS data, the rate of primary heart diseases, pulmonary hypertension, and implantation of ICD, MCS and ECMO were different, and the long-term survival rate of 160 patients was higher than that reported by ISHLT. Conclusion The risk factors of mortality of Chinese heart transplant patients are different with their counterparts from western countries. Our corresponding peri-operative treatments and clinical strategies have produced satisfactory clinical outcomes.
