Abstract
OBJECTIVE Lung cancer has become the primary cause of cancer-related death now. New therapies targeting the molecular regulatory machinery were required imperatively. MicroRNAs and long noncoding RNAs can respectively or cooperatively function as oncogenes or tumor suppressor genes in human cancers. The present study identified that miR-449a was down-regulated in tissue of human lung cancer. In this study, we aimed to investigate the function of miR-449a in NL9980 and L9981 lung carcinoma cells lines and the relationship with lncRNA nuclear enriched abundant transcript 1 (NEAT1). MATERIALS AND METHODS miR-449a was profiled in several lung carcinoma cell lines by quantitative reverse transcription-polymerase chain reaction RT-PCR. We analyzed the effects of miR-449a overexpression on proliferation, apoptosis and cell cycle in L9981 cells. The regulatory relationship between miR-449a and NEAT1 was predicted in silico and further studied by miR-449a inhibitor and mimics assay. RESULTS miR-449a was expressed in four cell lines, which we selected, however miR-449a was in high level in NL9980 and in low level in L9981 (P < 0.05). When the miR-449a was the overexpression in L9981 cells, the cell growth was suppressed, and the apoptosis cells were promoted compared with the control group (P < 0.05). The G1/G0 became longer and S, G2/M became shorter (P < 0.05) by miR-449a overexpression. Further study of the interaction between miR-449a and NEAT1 show that NEAT1 was up-regulated when cells were transfected with miR-449a inhibitor, and NEAT1 was down-regulated when cells transfected with miR-449a mimics. CONCLUSIONS Our data indicate that miR-449a may function as a suppressor of lung cancer, and affects the expression of NEAT1 in lung cancer cells.

Propensity score weighting for addressing under-reporting in mortality surveillance: a proof-of-concept study using the nationally representative mortality data in China. Popul Health Metr 2015; 13:16. [PMID: 26161042 PMCID: PMC4496861 DOI: 10.1186/s12963-015-0051-3] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2014] [Accepted: 06/30/2015] [Indexed: 11/04/2022] Open
Abstract
Background National mortality data are obtained routinely by the Disease Surveillance Points system (DSPs) in China and under-reporting is a big challenge in mortality surveillance. Methods We carried out an under-reporting field survey in all 161 DSP sites to collect death cases during 2009–2011, using a multi-stage stratified sampling. To identify under-reporting, death data were matched between field survey system and the routine online surveillance system by an automatic computer checking followed by a thorough manual verification. We used a propensity score (PS) weighting method based on a logistic regression to calculate the under-reporting rate in different groups classified by age, gender, urban/rural residency, geographic locations and other mortality related variables. For comparison purposes, we also calculated the under-reporting rate by using capture-mark-recapture (CMR) method. Results There were no significant differences between the field survey system and routine online surveillance system in terms of age group, causes of death, highest level of diagnosis and diagnostic basis. The overall under-reporting rate in the DSPs was 12.9 % (95%CI 11.2 %, 14.6 %) based on PS. The under-reporting rate was higher in the west (18.8 %, 95%CI 16.5 %, 21.0 %) than the east (10.1 %, 95%CI 8.6 %, 11.3 %) and central regions (11.2 %, 95%CI 9.6 %, 12.7 %). Among all age groups, the under-reporting rate was highest in the 0–5 year group (23.7 %, 95%CI 16.1 %, 35.5 %) and lowest in the 65 years and above group (12.4 %, 95%CI 10.9 %, 13.6 %). The under-reporting rates in each group by PS were similar to the results calculated by the CMR methods. Conclusions The mortality data from the DSP system in China needs to be adjusted. Compared to the commonly used CMR method in the estimation of under-reporting rate, the results of propensity score weighting method are similar but more flexible when calculating the under-reporting rates in different groups. Propensity score weighting is suitable to adjust DSP data and can be used to address under-reporting in mortality surveillance in China.

Abstract
OBJECTIVE To investigate the financial burden of patients who had various stages of hepatitis B virus-related diseases and the level of alleviation from financial burden by health insurance schemes in Yunnan province of China. STUDY DESIGN A cross-sectional survey. METHODS Patients' information was consecutively recorded at the First Affiliated Hospital of Kunming Medical University, from December 2012 to June 2013. Consecutive cases of hepatitis B virus (HBV) (520), compensated cirrhosis (91), decompensated cirrhosis (198) and hepatocellular carcinoma (HCC) (131) were recruited from the outpatient and inpatient departments. The total direct costs, hospital charge, outpatient costs, hospitalization fees being reimbursed and household catastrophic health expenditure were estimated for each disease group. RESULTS The average annual direct costs for each disease group were 19,496 RMB for HBV, 28,466 RMB in compensated cirrhosis, 46,061 RMB for decompensated cirrhosis, and 33,044 RMB for HCC patients. Catastrophic health expenditure occurred in all four groups. Health insurance reimbursement released the financial burden incurred by medical expenses of patients under a high level of household economic status. Public health insurance schemes helped the patients to various extents. CONCLUSIONS Among these patient groups, direct costs represent a significant economic burden. Health expenditure and financing systems must be considered to prevent the increase of household catastrophe, particularly among the poor.

Abstract
OBJECTIVE To analyze the disease burden of chronic obstructive pulmonary disease (COPD) among people aged over 15 years in 1990 and 2010 in China. METHODS The estimation of China data for the Global Burden of Disease Study 2010 (GBD 2010) was used to analyze the mortality and prevalence as well as the years of life lost due to premature mortality (YLL), years lived with disability (YLD) and disability-adjusted life years (DALY) of COPD in China in 1990 and 2010 for Chinese people aged 15 years and above. The death rate and DALY rate of COPD in China in 1990 and 2010 were compared. RESULTS In 2010, 0.934 million people (0.534 million men and 0.400 million women) aged over 15 years died from COPD, decreased 34.5% (24.3% for men and 44.4% for women) compared with that in 1990 (1.425 million with 0.705 million men and 0.720 million women). There were 41.764 million COPD patients in 2010 (22.111 million men and 19.653 million women), increased 42.1% (41.7% for men and 42.6% for women) compared with 1990 (29.382 million patients with 15.599 million men and 13.783 million women). The mortality rate of COPD decreased for 61.5% from 2.352/100 000 in 1990 to 90.5/100 000 in 2010. The prevalence rate of COPD was 4.2% and 3.9% in 1990 and 2010, respectively. The DALY, YLL and YLD due to COPD was 16.598, 12.946, and 3.652 million person years, respectively in 2010. The YLD increased 42.3% compared with 1990 (2.567 million person years). From 1990 to 2010, the age-standardized DALY rate, YLL rate and YLD rate decreased from 4 120.1/100 000 to 1 575.9/100 000, from 3 756.9/100 000 to 1 235.6/100 000 and from 363.2/100 000 to 340.3/100 000, respectively. CONCLUSION Although there was significant decrease of DALY due to COPD in 2010, compared to 1990, the YLD burden is still increasing.

Abstract
OBJECTIVE To assess the burden of disease attributable to ambient particulate matter pollution in 1990 and 2010 in China. METHODS On the basis of the results of the Global Burden of Diseases Study 2010 (GBD 2010) for China's estimates, we used population attributable fractions (PAF) to examine the burden of disease (mortality and disability-adjusted life years (DALY)) attributable to ambient particulate matter pollution in 1990 and 2010 in China, with 95% uncertainty interval (95% UI) estimate, and increasing rate to explore the trends of attributed burden of disease across the study period of 20 years. RESULTS In 2010, 38.9% (95% UI: 27.0%-49.4%) of lower respiratory infections for < 5 years children, 27.2% (95% UI: 10.2%-37.5%) of lung cancer, 29.9% (95% UI: 25.8%-34.2%) of ischemic heart disease, 35.0% (95% UI: 27.4%-41.1%) of stroke, and 21.0% (95% UI: 10.7%-30.3%) of chronic obstructive pulmonary disease (COPD) for ≥ 25 years adults were attributable to ambient particulate matter pollution, which accounted for 1.235 (95% UI: 1.038-1.410) million deaths and 25.230 (95% UI: 21.770-28.600) million person years DALY in total, and increased by 33.4% and 4.0%, respectively by comparison with that in 1990 (0.926 million and 24.260 million person years). Lung cancer accounted for the largest increasing rate of 154.5% (from 0.055 million to 0.140 million) and 130.1% (from 1.330 million person years to 3.060 million person years), followed by ischemic heart disease (118.5%, from 0.130 million to 0.284 million, and 86.6%, from 3.280 million person years to 6.120 million person years) and stroke (41.0%, from 0.429 million to 0.605 million, and 33.8%, from 8.970 million person years to 12.000 million person years). The attributed mortality for both gender mostly occurred in age group of 60-79 years (male: 0.260 million and 0.404 million accounting for 53.7% and 54.8%; female: 0.214 million and 0.236 million accounting for 48.5% and 47.5%) both in 1990 and 2010. The age group of 40-79 years accounted for the most portion of attributed DALY for both gender (male: 8.458 million person years and 13.460 million person years accounting for 62.9% and 83.8%; female: 6.360 million person years and 7.152 million person years accounting for 58.9% and 78.0%). The increasing rates were higher for male than for female. CONCLUSION The burden of disease attributable to ambient particulate matter pollution was very high in China with significant increase in mortality and disability, which indicates the highly necessity for government to take actions to reduce ambient particulate matter pollution and its health hazards.

Abstract
OBJECTIVE To analyze and compare burden of disease caused by malignant tumor in China, 1990 and 2010. METHODS The indicators including prevalence, death, years of life lost (YLL), years lived with disability (YLD), and disability adjusted of life years (DALY) of malignant tumor from the results of Global Burden of Disease (GBD) 2010 were used to calculate the standardized prevalence rate, mortality rate, YLL rate, YLD rate and DALY rate with the 2010 national census data. The research described the prevalence, death, and burden of disease caused by malignant tumor and analyze the trend of these indicators in 1990 and 2010 in China. RESULTS In China from 1990 to 2010, the standardized prevalence rate of malignant tumor increased from 529.76/100 000 to 749.57/100 000 (increased by 41.49%); the standardized mortality rate decreased from 196.57/100 000 to 169.88/100 000 (decreased by 13.58%); the standardized DALY rate decreased from 5 206.56/100 000 to 4 150.86/100 000. In 2010, the top five standardized DALY rate of malignant tumor were lung cancer, liver cancer, gastric cancer, esophageal cancer, and colorectal cancer. Their standardized DALY rate were 892.21/100 000, 787.40/100 000, 521.36/100 000, 303.95/100 000, and 269.94/100 000, respectively. In all kind of malignant tumors, the burden of disease of lung cancer had the fastest-growing rate. The standardized mortality rate of lung cancer increased from 34.78/100 000 in 1990 to 41.09/100 000 in 2010; the standardized DALY rate increased from 830.77/100 000 in 1990 to 892.21/100 000 in 2010. The burden of disease of gastric cancer had the fastest-falling rate. The standardized mortality rate of gastric cancer decreased from 39.65/100 000 in 1990 to 23.79/100 000 in 2010; the standardized DALY rate decreased from 968.96/100 000 in 1990 to 521.36/100 000 in 2010. CONCLUSION The burden of disease caused by malignant tumor in China remained at high levels in 2010. The top five burden of disease of malignant tumor were lung cancer, liver cancer, gastric cancer, esophageal cancer, and colorectal cancer. The burden of disease of lung cancer had the fastest-growing rate and gastric cancer had the fastest-falling rate from 1990 to 2010 in China. Prevention and control of malignant tumor was still difficult.

Abstract
OBJECTIVE To analyze the death status of disease burden of cardiovascular and circulatory diseases in 1990 and 2010 in China, and to provide the basic information for cardiovascular and circulatory disease prevention and control. METHODS Using the results of the Global Burden of Diseases Study 2010 (GBD 2010) to describe the cardiovascular and circulatory diseases deaths status and disease burden in China. The measurement index included the mortality, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted life years (DALY). At the same time, we used the population from 2010 national census as standard population to calculate the age-standardized mortality rate and DALY rate, YLL rate and YLD rates which will describe the mortality status and disease burden of total and different types of cardiovascular disease. We also calculated the change in 1990 and 2010 for all indexes, to describe the change of the burden of disease in the 20 years. RESULTS In 2010, the total deaths of cardiovascular and circulatory diseases reached 3.136 2 million, the mortality rate reached 233.70 per 100 000 people and the age-standardized mortality rate was 256.90 per 100 000 people. The total DALYs, YLLs, and YLDs of cardiovascular and circulatory diseases reached 58.2055, 54.0488, and 4.1568 million person-years, respectively, and the age-standardized DALY rate, YLL rate and YLD rate were 4 639.04, 4 313.13, 325.91 per 100 000. In 1990, the deaths only 2.1675 million and the DALYs, YLLs and YLDs were 45.2679, 42.2922, and 2.9757 million person-years. The age-standardized mortality rate was 300.30 per 100 000 people. And the age-standardized DALY rate, YLL rate and YLD rate were 5 872.58, 5 523.42 and 349.16 per 100 000. Compared with the result in 1990, the total deaths, DALYs, YLLs, and YLDs were increased 44.72%, 28.58%, 27.80%, and 39.68%, respectively, while the age-standardized mortality rate, age-standardized DALY rate, age-standardized YLL rate, and age-standardized YLD rate were decreased 14.45%, 21.01%, 21.91%, and 6.66%, respectively. In 1990 and 2010, cerebrovascular disease caused the most DALYs (24.8768 and 30.1389 million person-years, respectively) compared with other types of cardiovascular and circulatory diseases, and followed by ischemic heart disease (10.1270 and 17.8858 million person-years). And the YLLs of cerebrovascular disease (24.3436 and 29.1726 million person-years) also the highest in different type of cardiovascular and circulatory diseases, ischemic heart disease (8.9919 and 16.0839 million person-years) was the second highest. The deaths of cerebrovascular disease and cerebrovascular disease increased from 1 340.6 and 450.3 thousands in 1990 to 1 726.7 and 948.7 thousands in 2010, respectively. The age-standardized mortality rate and DALY rate of cerebrovascular disease were decreased from 187.19 and 3 335.37 per 100 000 people in 1990 to 141.43 and 2 409.09 per 100 000 people. While in the ischemic heart disease, the age-standardized mortality rate, and DALY rate were increased form 62.53 and 1 318.38 per 100 000 people in 1990 to 77.89 and 1 428.31 per 100 000 people. CONCLUSION Burden of cardiovascular and circulatory disease became more and more serious in China, of which the cerebrovascular disease and ischemic heart disease were most serious.

Abstract
Viral load reduction facilitates recovery of antiviral T-cell responses. Dynamic alterations in intrahepatic viraemia clearance and immune cell reactivity during the early phase of nucleoside analogue (NA) therapy and the impact of these changes on HBeAg seroconversion are unknown. Fifteen HBeAg-positive chronic hepatitis B (CHB) patients were treated with adefovir dipivoxil. T-cell reactivity to HBV core and surface antigens were tested using ELISPOT assay from baseline to week 48 post-treatment (at 4-week intervals). Before and at week 12 of treatment, paired liver biopsies were analysed for intrahepatic HBV-DNA and cccDNA via real-time fluorescent PCR. In situ detection of CD4(+) , CD8(+) T cells and NK cells was analysed by immunohistochemistry. With viral load reduction, HBV-specific IFN-γ-producing CD4(+) T cells in patients with HBeAg loss were greatly enhanced and reached the highest level at week 12, with further increase observed between week 36 and week 48. After 12 weeks of treatment, total intrahepatic HBV-DNA and cccDNA had significantly decreased; however, there was no difference in the viral loads or extent of reduction between patients with and without HBeAg loss. Paralleling reduction in viral load, intrahepatic CD8(+) T lymphocytes increased in patients with HBeAg loss compared with baseline values. Only one patient without HBeAg loss exhibited similar results. Increased immune cells were observed in certain patients along with reduced hepatic viral loads during the second phase of HBV-DNA decline, which could promote the recovery of antiviral immunity and facilitate HBeAg loss.

Abstract
BACKGROUND Major adjuvant therapies for biliary tract cancer (BTC) include fluorouracil, gemcitabine and chemoradiation (CRT), but the optimum regimen remains inconclusive. AIM To compare these therapies in terms of patient survival rates after resection and toxic effects. METHODS We searched PubMed for controlled trials comparing the above three therapies with each other or observation alone until 31 January 2014. We estimated the hazard ratios (HRs) for death and odds ratios (ORs) for toxic effects among different therapies. Subgroup analyses based on positive lymph node or resection margin were also performed. RESULTS Twelve eligible articles were included. Gemcitabine improved 5-year survival (HR 2.12, 95% CI, confidence interval 1.23-4.02, P = 0.01), whereas fluorouracil (HR 1.61, 95% CI 0.74-3.67) and CRT (HR 1.55, 95% CI 0.82-3.32) provided a poorer survival outcome compared with gemcitabine after 1 year. Similarly, for 5-year survival rates, although differing, CRT did not provide a significant improvement in survival (HR 0.46, 95% CI 0.20-0.97) compared with gemcitabine. Fluorouracil did not appear to provide benefit over gemcitabine (HR 1.56, 95% CI 0.77-3.35). CRT was ranked highest for toxic effects including haematological (OR 5.45, 95% CI 0.01-483.85) and nonhaematological (OR 5.77, 95% CI 0.01-3807.40). CONCLUSIONS Chemotherapy with gemcitabine is the optimum adjuvant treatment with a balanced benefit-toxicity ratio for resected biliary tract cancer. Chemoradiation was more likely to cause toxic effects.

Abstract
Bromodomain-containing protein 4 (BRD4) is an important epigenetic reader implicated in the pathogenesis of a number of different cancers and other diseases. Brd4-null mouse embryos die shortly after implantation and are compromised in their ability to maintain the inner cell mass, which gives rise to embryonic stem cells (ESCs). Here we report that BRD4 regulates expression of the pluripotency factor Nanog in mouse ESCs and preimplantation embryos, as well as in human ESCs and embryonic cancer stem cells. Inhibition of BRD4 function using a chemical inhibitor, small interfering RNAs, or a dominant-negative approach suppresses Nanog expression, and abolishes the self-renewal ability of ESCs. We also find that BRD4 associates with BRG1 (brahma-related gene 1, aka Smarca4 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a, member 4)), a key regulator of ESC self-renewal and pluripotency, in the Nanog regulatory regions to regulate Nanog expression. Our study identifies Nanog as a novel BRD4 target gene, providing new insights for the biological function of BRD4 in stem cells and mouse embryos. Knowledge gained from these non-cancerous systems will facilitate future investigations of how Brd4 dysfunction leads to cancers.

Abstract
BACKGROUND The processing of proprotein convertase (PC)-mediated neuropeptide plays a very important role in carcinogenesis and tumor proliferation. AIM To investigate proneuropeptide processing mechanism in tumorigenesis and tumor proliferation. MATERIALS AND METHODS The expression and processing profiles of PC1, carboxypeptidase E (CPE), PC2, GHRH, or neuropeptide Y (NPY) gene and protein level were investigated between 42 human breast tumor tissues and 21 tumor-adjacent normal tissues. RESULTS Gene analyses indicated that the proPC1, CPE, or preproNPY gene had higher expression in the breast tumor tissues, whereas the proPC2 or preproGHRH gene showed lower expression in the tissues. Protein analyses showed that the proPC1, PC1, CPE, GHRH, and preproNPY proteins were upregulated in the tumor tissues, whereas the proPC2, PC2, preproGHRH, and NPY proteins were down-regulated in them. The tissue results were highly corroborated with the serum data from the tumor patients and healthy women. CONCLUSIONS The higher PC1 and CPE expressions as well as the transformation of more proGHRH into active GHRH peptide suggest stronger PC1/CPE-mediated neuropeptide processing in the tumor, whereas the lower PC2 expression as well as the transformation of less proNPY into active NPY peptide suggests a weak PC2-mediated processing in it. The alterations of the convertase expressions and processing show that there is a differential proprotein processing system in the tumor, which leads to the abnormal distributions of species, ratio, and concentration of (pro)peptide(s) in the microenvironment of cells. The latter may contribute to cancer progression.

Abstract
BACKGROUND Indigenous Australians have higher prevalence of chronic diseases and worse acute care outcomes than other Australians. The extent to which higher chronic disease comorbidity levels are responsible for their worse outcomes is not clear, and the performance of comorbidity indices has not been assessed for this population with very high comorbidity levels. METHODS Using hospital separations data, the Charlson and Elixhauser comorbidity indices were used to measure chronic disease prevalence in 2035 indigenous and non-indigenous patients hospitalised after their first acute myocardial infarction (AMI) in the Northern Territory of Australia between 1992 and 2004, and to adjust for comorbidity in multivariate analysis of mortality outcomes (in-hospital and long-term deaths from coronary heart disease and all causes). Index performance was assessed by the difference between C statistic, Akaike information criterion statistic and estimate of excess indigenous mortality in models with and without comorbidity adjustment. RESULTS Comorbidity index scores were higher for indigenous than non-indigenous patients and increased considerably over time, at least partly because of information bias. Indigenous patients' higher risk of in-hospital all-cause death was almost fully explained by their higher comorbidity levels. Their higher risk of long-term coronary heart disease and all-cause death was partially explained by higher comorbidity levels. Charlson and Elixhauser indices performed satisfactorily and similarly in this population. CONCLUSION Comorbidity indices performed well in a population with very high chronic disease prevalence. After adjusting for comorbidity, short-term outcomes were similar for indigenous and non-indigenous AMI patients, but comorbidity at the time of the acute episode only partly explained the worse long-term outcomes for indigenous patients.

Abstract
Human bone marrow-derived mesenchymal stem cells (MSCs) have multi-lineage differentiation potential and can become cells of mesodermal and neural lineages. These stem cells thus hold considerable clinical promise for the treatment of neurodegenerative diseases. For successful regeneration of damaged neural tissues, directed differentiation of neural or neuronal precursor cells from MSCs and integration of transplanted cells are pivotal factors. We induced MSCs into neurogenesis using a modified protocol. The therapeutic potency of the resulting neural progenitor cells in a rat model of ischemic stroke was analyzed. Using a highly hydrophobic diphenylamino-s-triazine-bridged p-phenylene (DTOPV)-coated surface and adopting a procedure for propagation of neural stem cells, we efficiently converted MSCs into neurosphere-like cellular aggregates (NS-MSCs). The spherical cells were subsequently induced to differentiate into neural cells expressing neuroectodermal markers. To determine whether these cells had neuronal fates and induced neuro-protective effects in vivo, NS-MSCs were intra-cerebrally administered to rats 48h after permanent middle cerebral artery occlusion (pMCAo). The results showed a remarkable attenuation of ischemic damage with significant functional recovery, although the cells were not fully incorporated into the damaged tissues on post-operative day 26. Improvement in the NS-MSC-transplanted rats was faster than in the MSC group and suppression of inflammation was likely the key factor. Thus, our culture system using the hydrophobic surface of a biocompatible DTOPV coating efficiently supported neural cell differentiation from MSCs. Neural-primed MSCs exhibited stronger therapeutic effects than MSCs in rat brains with pMCAo.

Abstract
A commercially available cationic surfactant, dimethyl-dioctadecyl ammonium bromide (DDAB), was used for making lipid vesicles. DDAB easily dissolved in water at 60 °C and formed lipid vesicles at room temperature. The lipid vesicles showed very low cytotoxicity compared with other cationic surfactants. After the lipid vesicles were mixed with plasmid DNA solution, the solution was added to mammalian cells. The addition of a nonionic surfactant (Tween 80) to the cationic lipid vesicles at the weight ratio of 1:1 enhanced transfection efficiency. Adding more or less than the optimal amounts of DNA and lipid vesicles resulted in decreased transfection efficiency. With the optimal amounts of DNA (pCMVβ) and lipid vesicles, about 90-95% of CHO-K1 and BHK-21C13 cells transiently expressed β-galactosidase activity 24 h after transfection. By this procedure, stable transformants around 10(5) cells corresponding to 10% efficiency could be obtained by one batch transfection.

Abstract
This study is to identify the more sensitive method to measure the brain activation by the visuospatial performance level by comparing two different methods of measuremtnt (i.e., a method calculating the number of activated voxels and the other, the mean intensity of activated voxels). Sixteen right-handed male college students (mean age 23.2 years) participated in this study and function brain images were scanned with a 3T MRI using the single-shot EPI method during visuospatial performance. There found no brain areas with correlation between the visuospatial performance level and number of activated voxels. However, there found a sifgnificant correlatgion between the visuospatial performance level and the mean intensity of selected activated voxels in the parietal, frontal, and other areas.f In conclusion, the method of meanintensity rather than the one of the number is considered as a better index.

Abstract
Abstract
Preoperative breast MRI has been increasingly performed in patients with newly diagnosed breast cancer due to its high sensitivity in assessing the extent and additional malignant foci. But due to it's low specificity, role of routine preoperative breast MRI has become an issue. In this study we aught to analyze the characteristics of the additional lesion found in preoperative breast MRI and to evaluate the clinicopathological factors in association with likelihood of having additional malignancy.
We retrospectively reviewed 2491 patients who undergone surgery due to breast cancer in Seoul National University Hospital(SNUH) between Jan 2006 and Dec 2010. Neoadjuvant chemotherapy cases, patients undergone initial sonography in other center or ones with prior excision were excluded and total 1068 patients were analyzed. The additional lesion was defined as the lesion not found in initial sonography and detected in preoperative breast MRI. The pathology of the additional lesion was reviewed and the association between the clinicopathologic factors and additional malignancy were evaluated. Accuracy of breast MRI was estimated regarding cancer yield, positive predictive value(PPV).
Mean age at diagnosis was 50.9 years (21 to 85 years). Overall detection rate of additional lesion was 26.2%(280 out of 1068). Mean size of the additional lesion was 9.8mm(3-51). Additional lesions consist of 99(35.4% of 280) C4 or higher, 174(62.1% of 280) below C4, 7(2.5% of 280) C0 lesions. Among them 100 patients undergone onstage surgery. 5(55% of 100) lesions were in ipsilateral breast and 45(45% of 100) in contralateral breast. Breast conserving surgery and mastectomy rate of the 100 onstage-operation group was 36% versus 64% and 64.6% versus 35.4% in total 1068 patients, showing no significant change of operation method of the primary cancer owing to additional lesion.
Among the 100 patients, 54(19.3% of 280) were benign, 3(1.1% of 280) were atypical ductal hyperplasia, 13(4.6% of 280) were in situ carcinoma, 19(6.8% of 280) were invasive carcinoma and 11(3.9% of 280) were unknown. Cancer yield was 2.99%(32 out of 1068) and PPV of preoperative breast MRI was 39.0%(31 out of 82).
In univariate analysis, young age and premenopausal patients showed to have higher rate of additional cancer found in MRI(p=0.022, p=0.036). Breast density, size and LN status of the primary cancer didn't show significancy and neither the hormone receptor status with each p value 0.705, 0.381, 0.973, 0.375 respectively. Lobular carcinoma(ILC or mixed IDC with ILC) and low grade carcinoma showed significancy of having additional malignancy (p=0.019, 0.022). In multivariate analysis age, low grade carcinoma and lobular carcinoma showed independent association with p value 0.014, 0.039, 0.035 respectively(HR 0.95, 95%CI:0.94 o 0.99),(HR 0.39, 95%CI:0.16 to 0.96),(HR 5.66, 95%CI:1.13 to 28.39).
Routine preoperative breast MRI use can result in overtreatment also with delay in surgical management. In our data, younger age, low grade carcinoma, lobular carcinoma showed independent association having additional malignant foci in breast MRI. With the basis of mammography and sonography, preoperative breast MRI should only be done when additional gain is considered to overcome the flaws.

Abstract
The size of perivitelline space (PVS) is closely related with the frequency of polyspermic fertilization in pig oocytes. It has been reported that enlargement of PVS is attributed to accumulation of glycoproteins synthesised and secreted from cumulus cells and that culture of immature oocytes in low-salt medium enlarges PVS in pigs. This study examined the developmental competence of pig oocytes after parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) in relation to the size of the PVS of oocytes matured in vitro (IVM). Cumulus–oocyte complexes were matured in medium 199 (Experiment 1) or porcine zygote medium (PZM)-3 (Experiment 2) supplemented with pig follicular fluid, cysteine, pyruvate, EGF, insulin, and hormones for the first 22 h and then cultured in hormone-free medium for an additional 22 h. IVM oocytes were activated electrically for PA or used as recipient cytoplasts for SCNT. PA and SCNT embryos were cultured for 7 days in PZM-3 medium supplemented with bovine serum albumin. The intracellular glutathione (GSH) level in IVM oocytes was determined by analysing the fluorescence intensity of oocytes after staining with CellTracker Blue CMF2HC. The expression of CDK1, PCNA, and ERK2 mRNA in IVM oocytes was analysed by RT-PCR. Data were analysed using a general linear model procedure followed by the least significant difference mean separation procedure when the treatments differed at P < 0.05. In Experiment 1, oocytes with a larger PVS had higher (P < 0.05) levels of intracellular GSH (1.0 pixels/oocyte v. 0.6 pixels/oocyte) and blastocyst formation (54% v. 37%) after PA than oocytes with smaller PVS. In Experiment 2, maturation culture of oocytes in PZM-3 with reduced (61.6 mM) NaCl concentration significantly increased (P < 0.05) the size of the PVS (5.2 μM v. 3.3 μM) compared with control oocytes that were matured in PZM-3 containing 108 mM NaCl, although the treatment did not alter the nuclear maturation. Moreover, oocytes with increased PVS expressed more CDK1, PCNA, and ERK2 mRNA and had higher (P < 0.05) intracellular GSH levels (1.6 pixels/oocyte v. 1.2 pixels/oocyte) and increased blastocyst formation after PA (52% v. 41%) and SCNT (32% v. 18%) compared with control oocytes. Our results demonstrate that pig oocytes with a large PVS have greater developmental competence after PA and SCNT, which is attributed to improved cytoplasmic maturation resulting from the enhanced GSH level and transcription factor expression and that enlargement of PVS by the culture in low-NaCl medium also improves developmental competence of pig oocytes.

Abstract
BACKGROUND Fluid management during orthotopic liver transplantation poses unique challenges for the anesthesiologist. Maintenance of hypovolemia as indicated by low central venous pressure has been associated with reduced blood loss and improved outcomes in some studies, but with higher 30-day mortality and increased incidence of renal dysfunction in others. The primary aim was to evaluate the association of central venous pressure management after liver allograft reperfusion with immediate postoperative patient outcomes. METHODS This was a retrospective investigation evaluating the intraoperative and postoperative records of 144 consecutive patients who underwent orthotopic liver transplantation at a single institution. RESULTS We did not find any important association between central venous pressure management after graft reperfusion and postoperative patient outcomes. Specifically, these data do not support the hypothesis that maintenance of lower central venous pressure during the post-anhepatic phase of orthotopic liver transplantation is associated with improved immediate postoperative allograft function (except for a steeper decrease in post operative days 1-3 in 2 of the 3 liver function test: alanine aminotransferase and bilirubin) or overall patient survival, graft survival, composite graft/patient survival, intensive care length of stay, hospital length of stay or the occurrence of infections. CONCLUSION Maintaining a lower central venous pressure during the post-anhepatic phase during orthotopic liver transplantation is not associated with any benefit in terms of immediate postoperative allograft function, graft survival or patient survival.
