RESUMO
Objective: To investigate the effect of Dapagliflozin, sodium-glucose cotransporter 2 inhibitor (SGLT2i), on contrast-induced acute kidney injury (CIAKI) in patients with type 2 diabetes mellitus (T2DM) after percutaneous coronary intervention(PCI). Methods: A cohort study. The clinical data of 366 patients with coronary heart disease combined with T2DM who underwent PCI in the Department of Cardiology, Tianjin University Chest Hospital, from June 2021 to June 2022 were retrospectively analyzed, including 218 males and 148 females, aged (64.6±11.0) years old. According to whether the patients had used Dapagliflozin or not, the selected patients were divided into SGLT2i group(n=124) and control group(n=242). The changes in cardiac indicators, renal function, and inflammatory response indicators before and 72 hours after PCI treatment were analyzed and compared between the two groups. The incidence rate of CIAKI in the two groups was analyzed, and the influencing factors of CIAKI were analyzed by multivariate logistic regression. The major adverse cardiac events (MACE) were recorded during the follow-up period of the two groups, and Kaplan-Meier survival analysis and log-rank test were used to compare the differences in MACE occurrence between the two group. Results: The left ventricular ejection fraction (LVEF) of the SGLT2i group was lower than that of the control group, and the proportion of patients with LVEF<45% and CIAKI risk score were higher than those of the control group, with statistical significance (all P<0.05). 72 h after PCI treatment, ß-2 Microglobulin(ß-2MG), cystatin-C(Cys-C), and neutrophil gelatinase-associated lipocalin (NGAL) in both groups were all increased compared to those before PCI treatment, with statistical significance (all P<0.05).ß-2MG, Cys-C, and NGAL in SGLT2i group were all lower than those in the control group, with statistical significance(all P<0.05).The levels of interleukin-6(IL-6), hypersensitive C-reactive protein (hs-CRP), and malondialdehyde in both groups of patients increased compared to preoperative levels, while the levels of superoxide dismutase (SOD) decreased compared to preoperative levels, with statistical significance (all P<0.05). The levels of IL-6, hs-CRP, and malondialdehyde in the SGLT2i group were lower than those in the control group, while SOD was higher than that in the control group, with statistical significance (all P<0.05). Among all patients included, 34 cases experienced CIAKI (9.8%), and the incidence of CIAKI in the SGLT2i group was lower than that in the control group [4.8% (6/124) vs 11.6% (28/242),P=0.037]. Multivariate logistic regression analysis showed that the use of dapagliflozin was a protective factor for CIAKI in T2DM patients receiving PCI treatment (OR=0.321, 95%CI: 0.127-0.816, P=0.017). After a follow-up of 14.0 (12.0, 16.2) months, the incidence of MACE in SGLT2i group was lower than that in the control group (7.3% vs 12.8%, P=0.048). Conclusions: Dapagliflozin may reduce the risk of CIAKI and MACE in T2DM patients after PCI treatment. Its mechanism may be related to the anti-inflammatory and antioxidant effects of SGLT2i.

BACKGROUND: Brain metastasis (BRM) is uncommon in gastroesophageal cancer. As such, clinicopathologic and molecular determinants of BRM and impact on clinical outcome remain incompletely understood. METHODS: We retrospectively analyzed clinicopathologic data from advanced esophageal/gastroesophageal junction (E/GEJ) patients at Johns Hopkins from 2003 to 2021. We investigated the association between several clinical and molecular features and the occurrence of BRM, with particular focus on human epidermal growth factor receptor 2 (HER2) overexpression. Survival outcomes and time to BRM onset were also evaluated. RESULTS: We included 515 patients with advanced E/GEJ cancer. Tumors were 78.3% esophageal primary, 82.9% adenocarcinoma, 31.0% HER2 positive. Cumulative incidence of BRM in the overall cohort and within HER2+ subgroup was 13.8% and 24.3%, respectively. HER2 overexpression was associated with increased risk of BRM [odds ratio 2.45; 95% confidence interval (CI) 1.10-5.46]. On initial presentation with BRM, 50.7% had a solitary brain lesion and 11.3% were asymptomatic. HER2+ status was associated with longer median time to onset of BRM (14.0 versus 6.3 months, P < 0.01), improved median progression free survival on first-line systemic therapy (hazard ratio 0.35, 95% CI 0.16-0.80), and improved median overall survival (hazard ratio 0.20, 95% CI 0.08-0.54) in patients with BRM. CONCLUSION: HER2 overexpression identifies a gastroesophageal cancer molecular subtype that is significantly associated with increased risk of BRM, though with later onset of BRM and improved survival likely reflecting the impact of central nervous system-penetrant HER2-directed therapy. The prevalence of asymptomatic and solitary brain lesions suggests that brain surveillance for HER2+ patients warrants prospective investigation.

Objective: To examine the early and midterm surgical outcome of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCA) using revised surgical strategies. Methods: A retrospective analysis of clinical data, surgical methods, and follow-up results was performed of 104 cases of PA/VSD/MAPCA in Department of Cardiovascular Surgery, Guangzhou Women and Children's Medical Center from January 2017 to September 2022. There were 55 males and 49 females, aged (M(IQR)) 33.9(84.0) months (range: 0.5 to 209.6 months) at the first surgical procedures. The anatomical classification included 89 cases of type B and 15 cases of type C. The number of major aortopulmonary collateral arteries was 4.2 (3.0) (range: 1 to 8). The Kaplan-Meier method was used for survival estimation. Results: In the first stage of surgery, 50 patients underwent a complete primary repair, 12 patients underwent partial repair, 32 patients underwent palliative right ventricular-pulmonary artery connection, and only 10 patients chose the Blalock-Taussig shunt. There were 10 cases of early death. In the second stage, 14 patients underwent complete repair and 4 patients underwent partial repair with no early death. The interval between the two surgeries was 19 (10) months (range: 9 to 48 months). Finally, during the 40 (34) months follow-up period, a total of 64 patients were complete repair and the right/left ventricular pressure ratio after complete repair was 0.63±0.16 (range: 0.36 to 1.00). Survival analysis showed that survival rates at 1 and 5 years after first-stage surgery were both 89.4% (95%CI: 83.5% to 95.3%). At 28 (34) months (range: 1 to 67 months) of follow-up after complete repair, the survival analysis showed that the survival rates at 1 and 5 years were both 95.2% (95%CI: 89.9% to 100%). Conclusions: Using combined approaches tailored to individual patients and optimized unifocalization strategy, the complete repair rate at one stage and the cumulative complete repair rate at 5 years improved significantly with a lower right/left ventricular pressure ratio and satisfactory early and intermediate survival.

Objective: To evaluate the transitions of frailty status and related factors influencing its worsening in middle-aged and elderly adults. Methods: Data was obtained from the Beijing MJ Health Screening Center. A total of 13 689 participants who attended health checkups at least twice during 2008-2019 and had more than three years' intervals during these two health checkups were included in the study. The frailty index comprising 28 variables was used to measure frailty status. Frailty was defined as frailty index ≥0.25, and prefrailty was defined as frailty index >0.10 and <0.25. Logistic regression analysis was performed to investigate the association of socio-demographic factors and lifestyle characteristics with the worsening of frailty status, stratified by frailty status at the first health checkup. Results: The mean age at the first and last health checkups were (42.3±9.2) and (47.9±9.3) years, respectively. The mean interval during these two health checkups was (5.7±1.9) years. At the first health checkup, the prevalence of frailty and prefrailty were 2.5% and 50.3%, respectively. While at the last health checkup, the prevalence of frailty and prefrailty rose to 3.9% and 55.4%. Of all participants, 67.3% remained in the same frailty state, 21.2% worsening, and 12.5% improving. In robust participants at the first health checkup, older age, female, low education level, smoking cessation, daily smoking, being general obesity measured by BMI or central obesity measured by WHR showed an increased the risk of worsening frailty status. However, in prefrail participants at the first health checkup, older age, female, general, or central obesity presented as risk factors for worsening frailty status. Conclusion: Modifiable factors such as low education level, smoking, and obesity may increase the risk of worsening frailty status.

OBJECTIVE: Long non-coding RNA SUMO1P3 has been reported to act as an oncogene in the tumorigenesis of several types of human malignancy. However, to the best of our knowledge, the exact biological functions and potential mechanism of lncRNA SUMO1P3 in glioma remains unknown. Therefore, the aim of this study was to investigate the potential role of SUMO1P3 in glioma and to explore the underlying mechanism. PATIENTS AND METHODS: The present study examined SUMO1P3 expression in glioma tissues and cell lines using reverse transcription-quantitative polymerase chain reaction. Cell Counting Kit-8 (CCK-8) and transwell assays were used to examine the effects of SUMO1P3 on the proliferation and invasion of glioma cells, respectively. Furthermore, Western blot was used to detect the expression levels of proteins in the epithelial-mesenchymal transition (EMT) process. RESULTS: The expression level of SUMO1P3 was higher in glioma tissues compared with corresponding adjacent normal tissues. In addition, a high expression level of SUMO1P3 was significantly associated with clinical progression and poor survival for patients with glioma. Furthermore, the knockdown of SUMO1P3 inhibited the proliferation, migration and invasion of U87 and U251 cells. In addition, the knockdown of SUMO1P3 inhibits glioma growth in vivo. Finally, the knockdown of SUMO1P3 inhibited the epithelial-mesenchymal transition and reduced the expression levels of active ß-catenin, C-myc, and cyclin D1 in U87 and U251 cells. By contrast, the overexpression of SUMO1P3 promoted glioma cell proliferation, migration, and invasion. CONCLUSIONS: SUMO1P3 promotes glioma cell proliferation, migration, and invasion, and may be involved in Wnt/ß-catenin signaling.

Objective: To evaluate the early results of pulmonary autograft mitral valve replacement (Ross â ¡ procedure) in infants with intractable congenital mitral valve lesions. Methods: Between August 2018 and September 2019, 6 infants underwent mitral valve replacement with a pulmonary autograft in Department of Cardiovascular Surgery, Guangzhou Women and Children's Medical Center. There were 2 males and 4 females.The age at surgery ranged from 50 days to 1 year old.Preoperative diagnoses included severe to critic mitral valve insuffiency in all patients, moderate mitral valve stenosis in 3 patients, and mitral valve prolapse in one. When the pulmonary autograft was harvested, a cuff of bovine or autologous pericardium was sewn onto the proximal (infundibular) end of the autograft ( "top-hat" configuration). The distal (pulmonary) end of the autograft was secured to the mitral annulus.At the level of the left atrial free wall, the pericardial cuff was progressively tailored and sewn onto the atrial wall to remain away from the ostia of the pulmonary veins and to maintain normal morphology of the autograft. The bovine jugular valved conduit was used to reconstruct the right ventricular outflow tract. Results: There was one early death due to sudden cardiac arrest at the night of surgery day. The remaining 5 patients were successfully recovered and discharged. Follow-up of survivors ranged from 3 to 13 months. Echocardiographic follow-up demonstrated the flow velocity across the mitral valve position was 1.5 to 2.3 m/s, with a means gradient of 4 to 6 mmHg (1 mmHg=0.133 kPa). Four patients showed mild mitral insuffiency, normal left atrium and ventricle size and left ventricle ejection fraction.One patient had moderate mitral insuffiency, pulmonary valve endocarditis, and reduced left ventricle ejection fraction. The clinical symptoms of all survivals improved significantly and the weight gain were satisfactory. Conclusion: Pulmonary autograft mitral valve replacement may be a feasible and effective remedial surgical strategy for young infants with intractable congenital mitral valve lesions.

Objective: To observe the clinical effect of tonsillectomy on IgA nephropathy (IgAN) after renal transplantation. Methods: From March 2011 to July 2018, 201 kidney transplantation recipients who were diagnosed of IgAN by transplant renal biopsy in the Department of Organ Transplantation of the First Affiliated Hospital of Sun Yat-sen University were retrospectively reviewed, of which 18 patients underwent tonsillectomy after renal biopsy. The clinical data of the 18 patients were collected, patient and kidney survival time and function of the transplanted kidney were analyzed. Results: Of the 18 recipients, 13 were male and 5 were female, with an average age of (36.0±10.9) years. All 18 patients survived during follow-up. Two patients returned to dialysis treatment 10 months and 14 months after tonsillectomy, respectively. The creatinine was 94 (78, 133) µmol/L, 95 (74, 139) µmol/L, 106 (87, 158) µmol/L and 95(81, 147) µmol/L before tonsillectomy, 3 months, 1 year and 2 years after tonsillectomy, respectively (P=0.206). Urinary protein quantification was 0.31 (0.16, 1.38) g/24 h, 0.34 (0.10, 1.42) g/24 h, 0.33 (0.11, 0.56) g/24 h and 0.25 (0.10, 0.50) g/24 h at the same time points, respectively (P=0.104). The two patients who returned to dialysis were diagnosed of IgAN by transplant renal biopsy because of elevated creatinine, proteinuria and hematuria, 9 years and 4 years after kidney transplant respectively. Renal biopsy suggested that glomerular and segmental sclerosis were 7/24, 5/24 and 1/6, 2/6, respectively. Additionally, interstitial fibrosis and tubular atrophy (IF/TA) were both occupied 30% in the biopsies, and tonsillectomy was performed 461 days and 1 077 days after diagnosis of IgAN, respectively. Conclusions: Tonsillectomy can maintain the stability of renal function and prevent the aggravation of proteinuria in IgAN patients after renal transplantation. However, if pathology suggests obvious glomerulosclerosis or IF/TA, tonsillectomy may not be effective.

Objective: To evaluate the association between the frequency of bowel movement (BMF) and the risk of Parkinson's disease (PD). Methods: In this study, 510 134 participants from the China Kadoorie Biobank (CKB) were included after excluding those who reported to had been diagnosed with cancer at baseline survey. The baseline survey was conducted from 2004 to 2008. The study used the data from the baseline survey and follow-up until December 31, 2016. Cox proportional hazards regression models were used to estimate the HRs and the 95%CIs of risk of PD diagnosis with BMF. Results: During an average follow-up period of (9.9±1.9) years, 808 participants were diagnosed with PD. Compared with participants who had bowel movements every day, the multivariable-adjusted HR (95%CI) for those who had bowel movements<3 times/week, once every 2-3 days, and>1 time/day were 3.62 (2.88-4.54), 2.13 (1.74-2.60), and 0.81 (0.63-1.05), respectively. The linear trend test results of the association between BMF and risk of PD diagnosis was significant (P<0.001). Compared with the participants who had bowel movements ≥1 time/day, the multivariable-adjusted HR (95%CI) for those who had bowel movements<1 time/day was 3.13 (2.32-4.23) within the 5 years of follow- up and was 2.48 (2.05-3.01) beyond the 5 years of follow-up. The gender specific results were similar. The association of BMF<1 time/day with risk of PD diagnosis was stronger in older participants. Conclusions: The participants with low BMF at baseline survey would have higher risk for PD diagnosis in the subsequent 10 years on average. Since abnormal decrease of BMF is easy to be found, programs could be set up for the early screening of PD in older people, along with other early symptoms of PD.

Objective: To examine the early- and midterm outcomes of pulmonary artery banding as an initial palliation in patients with single ventricle associated with unrestricted pulmonary blood flow. Methods: Between January 2008 and December 2017, 49 patients with single ventricle and unrestricted pulmonary blood flow underwent pulmonary artery banding at Department of Cardiac Surgery, Guangzhou Women and Children's Medical Center, Guangzhou Medical University. There were 29 males and 20 females. The age at the time of surgery was 5.6 (11.5) months (M(Q(R))), and the weight was 5.2 (3.9) kg. The medical records and results after pulmonary artery banding (death/reoperation, transition to the Glenn procedure) and subsequently after the Glenn procedure (death, transition to the Fontan procedure) were reviewed retrospectively. Actuarial survivals were estimated by the Kaplan-Meier curve. Relative factors for affecting outcomes were analyzed using the Cox regression hazard model. Results: There were 8 early deaths, with a mortality of 16.3%, including 4 cases who received simultaneous arch repair. There were 5 late deaths. During the follow-up of 47(62) (M(Q(R))) months, 11 patients (22.4%) underwent pulmonary artery banding adjustment, 29 patients (59.2%) underwent the Glenn procedure, 21 patients (42.8%) underwent the Fontan procedure. The survival of patients after the initial pulmonary artery banding were 77.4% (95%CI: 65.6% to 89.2%) and 72.6% (95%CI: 59.9% to 85.3%) at 1 year and 5 years, respectively. Multivariate Cox regression analysis revealed that systemic ventricular outflow tract obstruction (HR=4.25, 95%CI: 1.50 to 12.03, P=0.006) and total anomalous pulmonary venous connection (HR=6.49, 95%CI: 3.24 to 12.98, P=0.000) were relative factors for death. Conclusions: The early and midterm outcomes of pulmonary artery banding as an initial palliative strategy is not satisfactory. Systemic ventricular outflow tract obstruction and total anomalous pulmonary venous connection are associated with high mortality.

Objective: To examine the association between the frequencies of bowel movement (BMF) and the risk of colorectal cancer (CRC). Methods: In this study, 510 134 participants from the China Kadoorie Biobank (CKB) were included, after excluding those who reported as having been diagnosed with cancer at the baseline survey. The baseline survey was conducted from June 2004 to July 2008. The present study included data from baseline and follow-up until December 31, 2016. We used the Cox proportional hazards regression models to estimate the HR and the 95%CI of incident CRC with BMF. Results: During an average follow-up period of 9.9 years, 3 056 participants were documented as having developed colorectal cancer. In the site-specific analysis, 1 548 colon cancer and 1 475 rectal cancer were included. Compared with participants who had bowel movements on the daily base, the multivariable-adjusted HR (95%CI) for those who had more than once of BMF were 1.24 (1.12-1.39) for CRC, 1.12 (0.95-1.31) for colon cancer, and 1.37 (1.18-1.59) for rectal cancer. We further examined the association between BMF and CRC, according to the stages of follow-up, the corresponding HR (95%CI) for CRC, colon and rectal cancer were 1.59 (1.36-1.86), 1.43 (1.14- 1.80), and 1.76 (1.41-2.19) for the first five years, while such associations became statistically insignificant in the subsequent follow-up (P for all interactions were <0.05), as time went on. As for CRC, colon or rectal cancers among participants who had lower bowel movements, the risks were not significantly different from those who had bowel movements everyday. Conclusions: Participants who had BMF more than once a day, appeared an increased risk of CRC in the subsequent five years. Since abnormal increase of bowel movements is easily recognizable, programs should be set up on health self- management and early screening for CRC.

Objective: To investigate the efficacy of multistage surgery in patients with functional single ventricle (FSV) and risk factors of postoperative death. Methods: The clinical data of all consecutive patients with FSV undergoing multistage single ventricle palliation surgery in Guangzhou women and children's medical center from January 2008 to December 2017 were retrospectively reviewed. The study included 289 patients. The age was 10.0 (6.0, 35.4) months,and there were 198 male and 91 female patients. The patients were followed up at outpatient clinic. Survival rates were calculated with Kaplan-Meier. Multivariate Cox regression analysis was made to determine the risk factors of postoperative death. Results: Seventy-nine patients required the first stage palliation surgery, 232 patients received the Glenn shunt surgery, and 162 patients completed the Fontan procedure. Overall, postoperative death occurred in 39 patients including 21 after the first stage palliation surgery (early stage 13 cases, late stage 8 cases) , 10 after the Glenn shunt surgery (early stage 5 cases, late stage 5 cases) , and 8 following the Fontan procedure (early stage 6 cases, late stage 2 cases) . Kaplan-Meier analysis showed that survival rate of the entire cohort was 90.2% (95%CI 86.7%-93.7%) , 85.9% (95%CI 81.8%-90.0%) ,and 84.6% (95%CI 79.7%-89.5%) at 1 year, 5 years and 10 years post operation. Survival rate was 74.4% (95%CI 64.8%-84.0%) , 73.0% (95%CI 63.2%-82.8%) , and 73.0% (95%CI 63.2%-82.8%) at 1 year, 5 years, and 10 years post the first stage palliation surgery, 97.8% (95%CI 95.8%-99.7%) , 95.2% (95%CI 92.3%-98.1%) , and 95.2% (95%CI 92.3%-98.1%) at 1 year, 5 years, and 10 years post Glenn shunt surgery, 95.6% (95%CI 92.5%-98.7%) and 93.7% (95%CI 88.8%-98.6%) at 1 year and 5 years post Fontan surgery. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (HR=5.47, 95%CI 2.71-11.04, P<0.001), atrioventricular valve regurgitation more than moderate (HR=2.52, 95%CI 1.32-4.79, P=0.005), systemic ventricular outflow tract obstruction (HR=3.47, 95%CI 1.30-9.29, P=0.013), and required the first palliation surgery (HR=3.12, 95%CI 1.59-6.15, P=0.001) were risk factors of postoperative death. Conclusions: The multistage surgery can effectively improve the survival of patientswith functional single ventricle and is associated with satisfactory long-term prognosis. Total anomalous pulmonary venous connection, atrioventricular valve regurgitation more than moderate, systemic ventricular outflow tract obstruction, and required the first palliation surgery are risk factors of postoperative death in these patients.

Benign prostatic hyperplasia is one of the most common diseases in the elderly male population. The urinary tract symptoms may increase the risk of falls and fractures. The results indicated that patients with benign prostatic hyperplasia could increase the risk of vertebral compression fractures in both the thoracic and lumbar spine and also hip fractures, but did not increase the risk of wrist fracture. INTRODUCTION: The relationship between benign prostatic hyperplasia and the development of fall-related fractures, especially vertebral compression fractures, has been seldom mentioned in the literature. This study aimed to evaluate the risk of developing vertebral compression fracture, hip fracture, and wrist fracture in patients with benign prostatic hyperplasia. METHODS: This study obtained claims data retrospectively from the National Health Insurance Research Database of Taiwan and identified 48,114 patients who were diagnosed as having benign prostatic hyperplasia. Subjects of the control cohort were individually matched at a ratio of 4:1 with those in the benign prostatic hyperplasia cohort according to age and the index day. Comorbidities were classified as those existing before the index day and included a previous fracture history, osteoporosis, myocardial infarction, congestive heart failure, diabetes mellitus, hypertension, cerebrovascular accident, etc. The end of the follow-up period of the analyses was the day when the patient developed new vertebral compression fractures, hip fractures, or wrist fractures, terminated enrollment from the National Health Insurance, or died or until the end of 2012. The study used the Cox proportion hazard model to determine the hazard ratio for developing new hip fractures. RESULTS: Patients with benign prostatic hyperplasia were significantly more likely than those in the control cohort to develop new vertebral compression fractures in the thoracic spine (0.43% vs. 0.40%, adjusted hazard ratio 3.03, confidence interval 2.12-4.31) and lumbar spine (1.26% vs. 1.23%, adjusted hazard ratio 4.12, confidence interval 3.39-5.01), and hip fracture (1.47% vs. 2.09%, adjusted hazard ratio 1.22, confidence interval 1.10-1.36), but does not increase the risk of wrist fracture (0.61% vs. 0.67%, adjusted hazard ratio 1.07, confidence interval 0.85-1.34). CONCLUSIONS: Patients with benign prostatic hyperplasia exhibited an increased risk of developing vertebral compression fractures in both the thoracic and lumbar spine and also hip fractures, but did not increase the risk of wrist fracture. However, more research is needed to confirm this trend in the clinical setting.

Objective: To evaluate the early- and mid-term outcomes of surgical atrioventricular valve (AVV) intervention in patients with functional single ventricle (FSV). Methods: The clinical data of 40 consecutive FSV patients who underwent surgical AVV intervention between January 2008 and December 2017 at Department of Cardiac Surgery, Guangzhou Women and Children's Medical Center, Guangzhou Medical University were reviewed retrospectively. There were 25 male and 15 female patients. The median age at AVV intervention was 4.5 to 204.0 months (M(Q(R)): 42.5 (59.7) months), and the median body weight was 6.0 to 55.4 kg (M(Q(R)): 13.8 (8.1) kg). The systemic AVV morphology included common AVV in 21 patients, mitral valve in 7 patients, tricuspid valve in 3 patients, and both mitral and tricuspid valve in 9 patients. At first surgical intervention, 15 patients had severe, 25 patients had moderate AVV regurgitation. The timings of the initial surgical intervention were at the first palliative, Glenn, between Glenn and Fontan, and Fontan stage in 5, 23, 4, and 8 patients, respectively. The methods of the initial surgical intervention were AVV repair in 31 patients, AVV replacement in 9 patients. Actuarial survivals were estimated by the Kaplan-Meier method. Prognosis factors for atrioventricular valve reoperation were analyzed using the Cox regression hazard model. Results: There were 6 early deaths, with a mortality of 15.0%. Thirty-four survival patients received a follow-up of 1 to 117 months (M(Q(R)): 44 (34) months). Survival of patients after the initial surgical intervention were 85.0% (95% CI: 74.0% to 95.9%), 79.3% (95% CI: 66.6% to 92.0%), and 79.3% (95% CI: 66.6% to 92.0%) at 1 year, 5 years and 10 years, respectively. In all, only 13 patients completed the Fontan procedure. Six patients underwent 8 reoperations, including AVV replacement in 5 patients, redo AVV repair in 3 patients. Freedom from AVV reoperation at 1 and 5 years was 89.8% (95% CI: 78.8% to 100%) and 79.4% (95% CI: 64.7% to 94.1%), respectively. Multivariate Cox regression analysis revealed that common AVV (HR=3.53, 95% CI: 1.63-7.67, P=0.020) was the prognosis factors for AVV reoperation. Conclusions: The early- and mid-term outcomes of surgical AVV intervention in FSV patients are not satisfactory. The mortality and reoperation rate are still high, and common AVV predicts the AVV reoperation after the initial surgical intervention.

BACKGROUND: Opsite (Smith & Nephew, Hull, UK) is widely used in wound care but its use in eye protection against corneal abrasion during major surgery is rarely reported. The purpose of the current study is to compare the effectiveness of using Opsite in eye protection with either wet gauze alone or with wet gauze following application of eye ointment in patients undergoing living donor liver transplantation (LDLT). METHODS: This is a prospective, double-blinded, randomized controlled trial. Forty-one patients undergoing liver transplantation were enrolled. One eye of each patient was protected with sterile gauze soaked with normal saline solution and covered with Opsite. Duratears (ALCON, Fort Worth, Tex, United States) ointment was applied to the other eye before covering it with sterile wet gauze and Opsite (ointment group). The corneal examination was carried out after fluorescein staining before and at the end of surgery by the same doctor. A Student t-test and a χ2 test were used for the statistical analyses. RESULTS: Forty-one patients with 82 eyes were observed in this study. No corneal epithelial defects were found in either the normal saline group or the ointment group. CONCLUSION: Opsite combined with wet gauze with or without additional eye ointment provided 100% protection against corneal abrasion in patients undergoing LDLT.

BACKGROUND: Blood loss during liver surgery is found to be correlated with central venous pressure (CVP). The aim of the current retrospective study is to find out the cutoff value of CVP and stroke volume variation (SVV), which may increase the risk of having intraoperative blood loss of more than 100 mL during living liver donor hepatectomies. METHOD AND PATIENTS: Twenty-seven adult living liver donors were divided into 2 groups according to whether they had intraoperative blood loss of less (G1) or more than 100 mL (G2). The mean values of the patients' CVP and SVV at the beginning of the transaction of the liver parenchyma was used as the cutoff point. Its correlation to intraoperative blood loss was evaluated using the χ2 test; P < .001 was regarded as significant. RESULTS: The cutoff points of CVP and SVV were 8 mm Hg and 13% respectively. The odds ratio of having blood loss exceeding 100 mL was 91.25 (P < .001) and 0.36 (P < .001) for CVP and SVV, respectively. CONCLUSION: CVP less than 5 mm Hg, as suggested by most authors, is not always clinical achievable. Our results show that a value of less than 8 mm Hg or SVV 13% is able to achieve a minimal blood loss of 100 mL during parenchyma transaction during a living donor hepatectomy. Measurements used to lower the CVP or increased SVV in our serial were intravenous fluids restriction and the use of a diuretic.

Objective: To understand the association between central obesity, assessed by waist circumference, and the risks for ischemic heart disease (IHD), major coronary event (MCE), and IHD death. Methods: After excluding participants with heart disease, stroke, cancer, COPD, and diabetes at baseline survey, we included a total of 428 595 participants from the China Kadoorie Biobank for the analysis. The baseline survey was conducted from June 2004 to July 2008. We used Cox proportional hazards model to estimate the hazard ratio (HR) and 95%CI. Results: During an average 9.1 years of follow-up (3 803 637 person-years), we documented 26 900 incident cases of IHD, 4 320 cases of MCE, and 2 787 of deaths from IHD. After adjustment for possible confounders and BMI, central obesity was found to be associated with increased risks for IHD, MCE, and IHD death. The adjusted HRs (for the participants who had waist circumference of 85.0-89.9 cm in men and 80.0-84.9 cm in women were 1.13 (95%CI: 1.09-1.17) for IHD, 1.15 (95%CI: 1.05-1.26) for MCE and 1.11 (95%CI: 0.98-1.24) for IHD death. The respective HRs for those central obese participants (men ≥90.0 cm, women ≥85.0 cm) were 1.29 (95%CI: 1.24-1.34), 1.30 (95%CI: 1.17-1.44) and 1.32 (95%CI: 1.16-1.51). Further stratification analysis according to BMI showed that the risks for incident IHD, MCE, and IHD death increased along with the increase of waist circumference even in the participants with normal weight. Conclusion: This large-scale prospective study revealed that central obesity was an independent risk factor for IHD in adults in China, and the risk of IHD would increase with the increase of waist circumference.

Background: Neoadjuvant anti-PD-1 may improve outcomes for patients with resectable NSCLC and provides a critical window for examining pathologic features associated with response. Resections showing major pathologic response to neoadjuvant therapy, defined as ≤10% residual viable tumor (RVT), may predict improved long-term patient outcome. However, %RVT calculations were developed in the context of chemotherapy (%cRVT). An immune-related %RVT (%irRVT) has yet to be developed. Patients and methods: The first trial of neoadjuvant anti-PD-1 (nivolumab, NCT02259621) was just reported. We analyzed hematoxylin and eosin-stained slides from the post-treatment resection specimens of the 20 patients with non-small-cell lung carcinoma who underwent definitive surgery. Pretreatment tumor biopsies and preresection radiographic 'tumor' measurements were also assessed. Results: We found that the regression bed (the area of immune-mediated tumor clearance) accounts for the previously noted discrepancy between CT imaging and pathologic assessment of residual tumor. The regression bed is characterized by (i) immune activation-dense tumor infiltrating lymphocytes with macrophages and tertiary lymphoid structures; (ii) massive tumor cell death-cholesterol clefts; and (iii) tissue repair-neovascularization and proliferative fibrosis (each feature enriched in major pathologic responders versus nonresponders, P < 0.05). This distinct constellation of histologic findings was not identified in any pretreatment specimens. Histopathologic features of the regression bed were used to develop 'Immune-Related Pathologic Response Criteria' (irPRC), and these criteria were shown to be reproducible amongst pathologists. Specifically, %irRVT had improved interobserver consistency compared with %cRVT [median per-case %RVT variability 5% (0%-29%) versus 10% (0%-58%), P = 0.007] and a twofold decrease in median standard deviation across pathologists within a sample (4.6 versus 2.2, P = 0.002). Conclusions: irPRC may be used to standardize pathologic assessment of immunotherapeutic efficacy. Long-term follow-up is needed to determine irPRC reliability as a surrogate for recurrence-free and overall survival.

Objective: To review current-era palliation outcomes of patients with heterotaxy and functional single ventricle in a single institution. Methods: The clinical data of 70 consecutive patients with heterotaxy undergoing multistage single ventricle palliation in Guangzhou Women and Children's Medical Center from January 2008 to December 2017 were retrospectively reviewed, and the prognosis factors for mortality were analyzed. There were 53 male and 17 female patients.The median age was 13.3 months (range: 6 days to 150 months). Single ventricle multistage palliation included 1(st) stage palliation surgery, 2(nd) bidirectional Glenn shunt, and 3(rd) stage modified Fontan.The Kaplan-Meier method was used to estimate the probability of survival. Multivariate analysis was performed by Cox regression model. Results: Sixty-two patients had right atrial isomerism while eight had left atrial isomerism. Eighteen patients (25.7%) required the first stage palliation. Fifty-five patients received the Glenn shunt, and the Fontan procedure was completed in 27 patients. Overall, mortality occurred in 17 patients (24.3%) including 9 after the first stage palliation, 6 after the Glenn shunt, and 2 following the Fontan procedure. Survival estimates for the entire cohort following surgery were 81% (95%CI: 72% to 90%), 74%(95%CI: 64% to 85%), and 74% (95%CI: 64% to 85%) at 1 year, 5 years and 10 years, respectively. Survival estimates following the first stage palliation were 56% (95%CI: 33% to 79%) and 49% (95%CI: 26% to 73%) at 1 year and 5 years, respectively. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (TAPVC) (HR=6.16, 95%CI: 1.65 to 22.95, P=0.007), atrioventricular valve regurgitation more than moderate (HR=3.81, 95%CI: 1.32 to 10.94, P=0.013) and required the first palliation surgery (HR=4.58, 95%CI: 1.34 to 15.72, P=0.016) were prognosis factors for overall mortality. Conclusions: The management of heterotaxy patients with functional single ventricle remains challenging, and the outcomes are continously improving in china. TAPVC, atrioventricular valve regurgitation more than moderate and required the first palliation surgery still are prognosis factors for overall mortality in heterotaxy syndrome.

Objective: To review the early and mid-term results of end-to-side anastomosis technique for interrupted aortic arch in neonates and infants. Methods: Clinic data of 46 patients were diagnosed as interrupted aortic arch in Department of Cardiac Surgery, Guangzhou Women and Children's Medical Center between January 2010 and December 2016 were analyzed retrospectively. Twenty-six cases were neonates. The median age underwent surgery was 23 days (range: 2 days to 8 years). Anatomical subtypes included 36 cases of type A and 10 cases of type B. There was no type C case. The reconstruction of the aortic arch was completed by an extended end-to-side anastomosis technique between the descending aorta and the undersurface of the proximal aortic arch. In 42 patients, all with intracardiac anomalies, had concomitant complete repair of intracardiac anomalies through a median sternotomy. The remaining 4 patients, all without intracardiac anomalies, an end-to-side anastomosis was constructed through a left thoracotomy. During follow-up, aortic arch recurrent obstruction, left ventricular outflow tract obstruction (LVOTO) and tracheal stenosis were focused. Results: There were 3 surgical deaths, with amortality rate of 6.5%. The remaining 43 patients survived after surgery. In 39 of these patients, deep hypothermic cardiac arrest (DHCA) strategy was used for brain protection, and the mean time of DHCA was (16±3) minutes. Eight patients underwent delayed sternal closure. The mean mechanical ventilation time and ICU stay time were (3.4±1.6) days (range: 2 to 12 days) and (6.4±2.7) days (range: 3 to 16 days) respectively. In 16 patients, all with tracheal or bronchial stenosis before surgery, mechanical ventilation was successfully evacuated, and no new airway stenosis occurred. There was no residual pressure difference between upper and lower extremity arterial blood pressure at discharge. Echocardiography showed normal arterial blood flow velocity in aortic arch. At a mean follow-up of (36.2±18.9) months (range: 6 months to 7 years), there were two patients lost and one late date. Four patients developed a recurrent stenosis at the aortic arch, of which two were severe, and the other two were mild. In 2 patients, both with mild LVOTO before surgery, no significant increase in the degree of obstruction was found during the follow-up. Two patients developed new mild to moderate LVOTO without clinical symptoms, and continued to follow up. In all patients, the tracheal or bronchial stenosis were extenuated, and there was no new progressive airway stenosis by regular bronchoscopy. Conclusions: The end-to-side anastomosis technique for the reconstruction of the aortic arch achieved excellent early and mid-term results in neonates and infants suffered from interrupted aortic arch. Reducing the anastomotic tension by extensive mobilization is the key to prevent postoperative early complications and late recurrent arch obstruction.

Objective: To investigate the preventive effect, possible mechanism and safety of probucol on contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD). Methods: A total of 641 patients with coronary heart disease were consecutively enrolled from Department of Cardiology, in Tianjin Chest Hospital, Tianjin TEDA International Cardiovascular Hospital, Tianjin First Central Hospital, Tianjin Fourth Central Hospital. They were randomly divided into probucol group (n=321) and control group (n=320). The probucol group was given oral probucol 500 mg twice daily for day 0 to day 3 after PCI; the control group was given only conventional therapy. All patients were given intravenous drip 0.9% sodium chloride solution before 12 to 24 hours of operation. The levels of serum creatinine (Scr), blood urea nitrogen (BUN), evaluate glomerular filtration rate (eGFR), cystatin C (Cys-C), and high-sensitivity C-reactive protein (hs-CRP), neutrophil gelatinase associated lipocalin (NGAL), superoxide dismutase (SOD) and glutathione (GSH) were measured before and 72 h after the PCI operation in both groups. The incidence rates of CIN, the adverse events during hospitalization and postoperative 14-day follow-up were recorded in two groups. Results: There was no statistically significantly difference in the levels of Scr, BUN, eGFR, Cys-C, hs-CRP, NGAL, SOD and GSH between the two groups before PCI (P>0.05). The levels of serum Scr, BUN, Cys-C, hs-CRP, NGAL, SOD and GSH after operation in the two groups were higher than those before the operation (P<0.05). The levels of hs-CRP and NGAL in the probucol group were lower than those in the control group [(10±4) vs (11±4)mg/L, (25±8)vs (34±7)U/ml, P<0.05]. The levels of eGFR, SOD and GSH in probucol group were higher than those in control group [(80±27) vs (72±26) ml·min(-1)·1.73 m(-2,) (67±9) vs (58±8)U/ml, (4.6±0.9) vs (3.9±0.8)U/ml, P<0.05]. The incidence of CIN was 4.0% in the probucol group and 10.9% in the control group, and the difference was statistically significant (P<0.05, χ(2)=-3.31). Multivariate Logistic regression analysis showed that probucol was an independent protective factor for CIN (OR=0.334, 95%CI 0.172-0.648, P=0.001). There were no adverse events such as myasthenia gravis, abnormal liver function and cardiovascular events during the hospitalization and 14-day follow-up. Conclusions: Probucol can reduce the incidence of contrast-induced nephropathy after PCI. The protection mechanism is related with its anti-inflammatory and anti-oxidative stress effects, and it has good safety.
