OBJECTIVETo compare 24 h ambulatory blood pressure changes between patients with renovascular hypertension and essential hypertension.
METHODSThe 24 h ambulatory blood pressure of patients with age and gender matched renovascular hypertension (RVH, n = 51) was compared with that of patients with essential hypertension (EH, n = 51).
RESULTSThe 24 h, daytime and nighttime systolic blood pressures (SBP), diastolic blood pressures (DBP) and pulse pressures (PP) in RVH were significantly higher than in EH (all P < 0.05), especially the nocturnal SBP (P < 0.05). The SBP and DBP loads in RVH were 58.96% and 35.98% respectively, while blood pressure loads were around 20.00% in EH (P < 0.05). In patients with RVH, The nocturnal blood pressure fall was 5.39%, and only 27.50% patients were dippers, while the nocturnal blood pressure fall was 10.36% and 60.8% patients were dippers in EH.
CONCLUSIONRVH patients have higher dynamic BP, PP, BP loads and blunted diurnal rhythm compared to those with EH.

BACKGROUNDChildhood cancer survivors were at risk of development of second malignant neoplasms. The aim of this study is to evaluate the incidence, risk factors and outcome of second malignant neoplasms in childhood cancer survivors in a tertiary paediatric oncology centre in Hong Kong, China.
METHODSWe performed a retrospective review of patients with childhood cancer treated in Children's Cancer Centre in Prince of Wales Hospital, Hong Kong, China between May 1984 and June 2009. Case records of patients who developed second malignant neoplasms were reviewed.
RESULTSTotally 1374 new cases aged less than 21-year old were treated in our centre in this 25-year study period. Twelve cases developed second malignant neoplasms with 10-year and 20-year cumulative incidence of 1.3% (95% confidence interval 0.3% - 2.3%) and 2.9% (95% confidence interval 1.1% - 4.7%) respectively. Another 4 cases were referred to us from other centres for the management of second malignant neoplasms. In this cohort of 16 children with second malignant neoplasms, the most frequent second malignant neoplasms were acute leukemia or myelodysplastic syndrome (n = 6) and central nervous system tumor (n = 4). Median interval between diagnosis of primary and second malignant neoplasms was 7.4 years (range 2.1 - 13.3 years). Eight patients developed second solid tumor within the previous irradiated field. Radiotherapy significantly increased the risk of development of second solid tumor in patients with acute lymphoblastic leukemia (P = 0.027). Seven out of 16 patients who developed second malignant neoplasms had a family history of cancer among the first or second-degree relatives. Nine patients died of progression of second malignant neoplasms, mainly resulted from second central nervous system tumor and osteosarcoma.
CONCLUSIONSCumulative incidence of second cancer in our centre was comparable to western countries. Radiotherapy was associated with second solid tumour among patients with acute lymphoblastic leukemia. Patients who developed second brain tumor and osteosarcoma had a poor outcome.

Serum hepatitis B core-related antigen (HBcrAg) was shown to predict the risk of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients undergoing treatment. We investigated the longitudinal profile of HBcrAg in entecavir (ETV)-treated CHB patients with subsequent HCC develop-ment. We identified HCC cases diagnosed at ≥1 year after ETV initiation. CHB patients without HCC (matched for age, sex, cirrhosis status, baseline hepatitis B virus [HBV] DNA lev-el, and ETV treatment duration) were identified as controls at an HCC:non-HCC ratio of 1:2. Serum samples were retrieved at baseline (ETV initiation) and at 3 and 5 years of ETV therapy for HBcrAg measurement (log IU/mL). In total, 180 patients (60 HCC patients matched with 120 CHB patients without HCC; median age, 56.5 years; 80.6% male; baseline HBV DNA, 5.9 log IU/mL; median follow-up, 6.8 years) were recruited. The median time from ETV initiation to HCC de-velopment was 3.2 years. HBcrAg levels were higher in HCC cases than in controls at all three time points: 5.69 log IU/ mL versus 5.02 log IU/mL (p=0.025), 4.23 log IU/mL versus 3.36 log IU/mL (p=0.007), and 3.86 log IU/mL versus 3.36 log IU/mL (p=0.009), respectively. ETV led to similar rates of decline in HBcrAg from baseline to 3 years in both groups (0.34 log IU/mL/year vs 0.39 log IU/mL/year, p=0.774), al-though the decline from 3 to 5 years was slower in the nonHCC group (0.05 log IU/mL/year) than in the HCC group (0.09log IU/mL/year, p=0.055). ETV time-dependently reduced HBcrAg in HCC and non-HCC patients. HBcrAg interpretation should consider the antiviral treatment duration.

Chinese Journal of Clinical Thoracic and Cardiovascular Surgery 2017;24(7):495-500
Objective To explore risk factors related to acute kidney injury (AKI) in children who underwent corrective surgery for tetralogy of Fallot (TOF). Methods We retrospectively analyzed the clinical data of 726 children with corrective procedures for TOF aged less than 3 years in our hospital from March 1st 2010 to March 1st 2013. Children with AKI were picked using Acute Kidney Injury Network criteria. Demographic and perioperative variables of the remaining patients were reviewed. Univariate analysis was performed to compare the AKI group (240 patients) with the non-AKI group (486 patients). Multivariable analysis was carried out to identify significant determinants of AKI. Results A total of 240 children were with AKI. The result of univariate analysis showed that there was a statistical difference in age, Nakata index, McGoon ratio, left ventricular end-diastolic volume index (LVEDVI), transannular right ventricular outflow tract (RVOT) patch, or fresh frozen plasma (FFP) in prime solution between the AKI group and the non-AKI group. Multivariable logistic regression showed that in older children (OR=1.425, 95% CI 1.071 to 1.983, P=0.011) with more transfusion of FFP in the priming solution (OR=1.486, 95% CI 1.325 to 2.674, P<0.001) led to higher morbidity of mild AKI. In addition, there was an increase in morbidity related to AKI when children had less Nakata index (OR=0.282, 95% CI 0.092 to 0.869, P=0.013). Conclusion Postoperative AKI increases in older children group. Infusion of more FFP in priming solution increases morbidity of AKI. The less Nakata index is significantly associated with severe AKI.

To investigate the iron deficiency (ID) in children with congenital heart disease (CHD) and find high risk factors of ID. Methods The clinical data of 227 pediatric patients with CHD from February to June 2016 were retrospectively analyzed. The incidence of ID according to the result of iron metabolism examination (serum ferritin <12 μg/L as the diagnostic criteria) was investigated. According to their basic CHD types, patients were divided into a cyanotic group and an acyanotic group. We tried to find the high risk factors of ID in those pediatric CHD patients by comparing their age, gender, growth condition and blood routine test results. Results There were 19.8% pediatric CHD patients complicated by ID. The incidence of ID in the cyanotic patients was higher than that in the acyanotic patients (31.0% vs. 17.3%, P=0.045). In both groups, ID patients presented the characteristics of younger age, higher anemia rate, lower mean corpuscular volume (MCV), lower mean corpuscular hemoglobin (MCH), lower mean corpuscular-hemoglobin concentration (MCHC) and longer red blood cell distribution width (RDW). Conclusion Cyanosis, younger age (infant), anemia, decreased MCV, decreased MCH, decreased MCHC and increased RDW are high risk factors of ID in CHD children.

OBJECTIVES: To overcome challenges in the implementation of electronic dental record systems in a low-resource setting, it is crucial to know the level of users’ satisfaction with the existing system of paper-based dental records and their perceptions of electronic dental records. METHODS: A cross-sectional paper-based questionnaire survey was conducted among Myanmar dental professionals who worked in one of two teaching hospitals or in private dental clinics. Descriptive data were analyzed and regression analysis was carried out to identify factors influencing perceptions of electronic dental records. RESULTS: Most dental professionals (>60%) were satisfied with just three out of six aspects of paper-based dental records (familiarity, flexibility, and portability). In addition, generalized positive perceptions were found among decision makers towards electronic dental records, and 86% of dentists indicated that they were willing to use them. Financial concerns were identified as the most important barrier to the implementation of electronic dental records among dentists who were not willing to use the proposed system. CONCLUSIONS: The first step towards implementing electronic dental records in Myanmar should be improvement of the content and structure of paper-based dental records, especially in private dental clinics. Utilization of appropriate open-source electronic dental record software in private dental clinics is recommended to address perceived issues around financial barriers. For the long term, we recommend providing further education and training in health informatics to healthcare professionals to facilitate the efficient use of electronic dental record software in Myanmar in the future.

OBJECTIVETo investigate the mechanism of autologous mesenchymal stem cells (MSCs) in prolonging the survival of dogs receiving living donor liver transplantation.
METHODSCanine models of allogenic living donor liver transplantation was established in 14 beagle dogs by non-venous by-pass method, and in 7 of the recipients, autologous MSCs labeled by BrdU was infused into the portal vein, with the other 7 dogs as the control. The survival time of the two groups of the dogs was observed after the operation. The liver function (AST and ALT levels), liver pathologies and the differentiation of the transplanted cells were also evaluated postoperatively.
RESULTSCompared with the control group, the dogs receiving MSC transplantation showed significantly increased median survival time (P<0.001) with lowered levels of AST and ALT (P<0.01). The two groups exhibited similar graft rejection after the operation. In dogs with MSC transplantation, the BrdU-labeled MSCs differentiated into liver-like cells in the liver and secreted albumin.
CONCLUSIONAutologous MSCs infusion through the portal vein during allogenic living donor liver transplantation can prolong the survival of the recipient dogs. The stem cells transplanted can differentiate into mature liver-like cells and secrete albumin in the hepatic tissue.

OBJECTIVETo analyze the in-hospital mortality and factors affecting in-hospital mortality for patients with transposition of the great arteries (TGA) undergoing arterial switch operation (ASO).
METHODSBetween January 2004 and December 2007, ASO was performed in 169 patients [129 male, 40 female; mean age (11.71 ± 26.3) months] with TGA. The patients were divided in intact ventricular septum group (n = 56): TGA with intact ventricular septum and ventricular septal defect group (n = 113): TGA with ventricular septal defect. Multiple logistic regression analysis was performed to identify the risk factors of in-hospital mortality.
RESULTSThe overall in-hospital mortality was 11.24% (19/169). The yearly in-hospital mortality was similar between intact ventricular septum group and ventricular septal defect group. With the improvement of perioperative treatment, the in-hospital mortality decreased from 16.67% in 2004 to 3.92% in 2007. The multivariate analysis revealed that body weight ≤ 3 kg (OR: 4.571, P = 0.0409), complicating ventricular septal defect (OR: 4.444, P = 0.0406), complex TGA (OR: 4.321, P = 0.0140), coronary anomalies (OR: 4.867, P = 0.0104) and non-type A coronary arteries (OR: 3.045, P = 0.0243) were independent predictors for poor early postoperative survival.
CONCLUSIONBody weight ≤ 3 kg, complicating ventricular septal defect, complex TGA, coronary anomalies are independent predictors for increased in-hospital mortality in patients with transposition of TGA and undergoing arterial switch operation.
