Complete spontaneous regression of giant focal nodular hyperplasia of the liver: Magnetic resonance imaging evaluation with hepatobiliary contrast media

Focal nodular hyperplasia(FNH) of the liver is a benign lesion occurring in 0.6%-3% of the general population that probably reflects a local hyperplastic response of hepatocytes to a vascular abnormality. Most lesions are diagnosed incidentally and the natural history of the disease remains largely unknown. It has been shown that most FNH remain stable, or even regress, over a long follow-up period. We present a patient with FNH of the liver who was followed up for 7 years. A 26-yearold woman with a 5-year history of oral contraceptive use was referred to our hospital in February 2005 for further examination of a liver tumour. The diagnosis of FNH was made using magnetic resonance(MR) imaging with hepatospecific contrast media; this technique allows a correct diagnosis, in particular distinguishing FNH from hepatic adenoma, avoiding an invasive procedure such as the lesion biopsy. After 7-year from the diagnosis, we observed the complete spontaneous regression of the lesion by enhanced MR scanning. In this patient, discontinuation of oral contraceptive use and two childbirths may have influenced the natural history of FNH. To our knowledge, in the English literature there is no report illustrating a complete regression of giant FNH but only studies of decreasing in size. The present case suggests that a young patient with giant FNH should be managed conservatively rather than by resection, because FNH has the potential for spontaneous regression.

Demographic determinants of risk,colon distribution and density scores of diverticular disease

AIM:To investigate associations between ethnicity,age and sex and the risk,colon distribution and density scores of diverticular disease(DD).METHODS:Barium enemas were examined in 1000 patients:410 male,590 female;760 whites,62 Asians,44 black africans(BAs),and 134 other blacks(OBs).Risks and diverticula density of left-sided DD(LSDD) and rightsided-component DD(RSCDD = right-sided DD + right and left DD + Pan-DD) were compared using logistic regression.RESULTS:Four hundred and forty-seven patients had DD(322 LSDD and 125 RSCDD).Adjusted risks:(1) LSDD:each year increase in age increased the odds by 6%(95% CI:5-8,SE:0.8%,P < 0.001);Asians:odds ratio(OR):0.23(95% CI:0.10-0.53,SE:0.1,P ≤ 0.001) and OBs:OR:0.25(95% CI:0.14-0.43,SE:0.07,P ≤ 0.001) appeared protected vs Whites;(2) RSCDD:each year increase in age increased the odds by 4%(95% CI:2-6,SE:1%,P < 0.001);females were 0.60 times(95% CI:0.40-0.90,SE:0.12,P = 0.01) less likely than males to have RSCDD;BAs were 3.51 times(95% CI:1.70-7.24,SE:1.30,P < 0.001) more likely than Whites to have RSCDD;and(3) DD density scores:each year increase in age increased the odds of highdensity scores by 4%(95% CI:1-6,SE:1%,P < 0.001);RSCDD was 2.77 times(95% CI:1.39-3.32,SE:0.67,P < 0.001) more likely to be of high density than LSDD.No further signif icant differences were found in the adjusted models.CONCLUSION:Right colonic DD might be more common and has higher diverticula density in the west than previously reported.BAs appear predisposed to DD,whereas other ethnic differences appear conserved following migration.

Modification of end-loop ileostomy for the treatment of ischemic or radiation enteritis

AIM: To evaluate a new technique of temporary ileal anastomotic stoma, following small bowel resection, in patients where the anastomosis is anticipated to have borderline margins with dubious viability. METHODS: Five patients underwent enterectomy and partially anastomosed end-loop ileostomy at the University Hospital of Larissa between 2000 and 2006. Enterectomy was performed because of conditions such as mesenteric vascular occlusive disease, radiation entritis and small bowel injury. RESULTS: Postoperatively, none of the patients developed any stoma-related or anastomotic complications. There were no major complications. All patients were discharged between the 8th and 15th day after the procedure, and the stoma was closed 3 wk to 4 wk later. CONCLUSION: We believe that our proposed modification of end-loop ileostomy is a simple, quick and safe technique with minimal stoma-related morbidity, and with simple and safe reversion. This technique can be considered as a useful option in the treatment of ischemic or radiation-induced enteritis, and in the management of severe intestinal trauma.

Pouchitis and pre-pouch ileitis developed after restorative proctocolectomy for ulcerative colitis:A case report

We report a case of pouchitis and pre-pouch ileitis, and inflammation in the neo-terminal ileum proximal to the pouch, developed after restorative proctocolectomy for ulcerative colitis. A 35-year old female presented with fever and abdominal pain five weeks after ileostomy closure following proctocolectomy. Computed tomography showed collection of feces in the pouch and proximal ileum. A drainage tube was placed in the pouch perianally, and purulent feces were discharged. With antibiotic treatment, her symptoms disappeared, but two weeks later, she repeatedly developed fever and abdominal pain along with anal bleeding. Pouchscopy showed mucosal inflammation in both the pouch and the pre-pouch ileum. The mucosal cytokine production was elevated in the pouch and pre-pouch ileum. With antibiotic and corticosteroid therapy, her symptoms were improved along with improvement of endoscopic inflammation and decrease of mucosal cytokine production. The fecal stasis with bacterial overgrowth is the major pathogenesis of pouchitis and pre-pouch ileitis in our case.

Uptake of prostate cancer screening and associated factors among Chinese men aged 50 or more: a population-based survey

Objective: To investigate the uptake rate of prostate specific antigen(PSA) testing among Hong Kong Chinese males aged 50 or above, and identify factors associated with the likelihood of undergoing a PSA test.Methods: A population-based telephone survey was conducted in Hong Kong in 2007. The survey covered demographic information, perceived health status, use of complementary therapy, cancer screening behavior, perceived susceptibility to cancer and family history of cancer. Descriptive statistics, percentages and logistic regression analysis were used for data analysis.Results: A total of 1,002 men aged 50 or above took part in the study(response rate =67%), and the uptake rate of PSA testing was found to be 10%. Employment status, use of complementary therapy, perceiving regular visits to a doctor as good for health and the recommendations of health professionals were significant factors associated with PSA testing.Conclusion: The uptake rate of PSA testing in the study population was very low. Among all the factors identified, recommendations from health professionals had the strongest association with the uptake of PSA testing, and they should therefore take an active role in educating this population about cancer prevention and detection.

Impacts of Social and Demographic Factors on Residents' Subjective Well-being in Rural China

The objective of social development is to construct a harmonious society.In China,the key to a harmonious society is the happiness of more than 900 million farmers living in the rural areas.This study aimed to measure rural residents' subjective well-being(SWB) through the day reconstruction method,as well as to analyze SWB's influencing factors through a variety of statistical methods.The results showed that the average U index was 12.79%,indicating that respondents were unhappy 12.79% of the time.Twenty-seven percent of the population had a U index greater than 0,with the average value being 47%,indicating that these people were unhappy 47% of the time.The study also found that SWB varied according to the characteristics of the respondents.Logistic regression analysis showed that social and demographic factors,including age,education,county,household size,generation number,per capita income,migration status and social networking,which significantly affected rural residents' SWB.The size of the impact varied with the different factors.

Factors Associated with Coronary Artery Disease in Young Population(Age≤40):Analysis with 217 Cases

Objective To investigate the relevant factors of coronary artery disease （CAD） in young people under 40 years of age. Methods The study population was 292 young patients accepting coronary angiography in Fuwai Hospital from July to December 2006, including 272 men and 20 women, with the mean age being 36.7±3.7 years. The diagnosis of CAD was made in the cases presenting ~ 50% stenosis in coronary lumen in coronary angiography. Based on the diagnosis, 217 patients （204 men, 13 women） were assigned to CAD group, and 75 （68 men, 7 women） to non-CAD group. Clinical data and metabolic characteristics of the patients were collected and analyzed using t-test, Z2 test, and multinomial logistic regression with SPSS 8.0 software. Results Most study subjects were current smokers （209/292, 71.6%）, and more than half had body mass index （BMI）〉24 kg/m2 （230/292, 78.8%） and usually took high-fat diet （162/292, 55.5%）. The proportion of heavy smokers （smoking history ≥10 years and t〉20 cigarettes per clay） were significantly higher in the CAD group than in the non-CAD group [20.7% （45/217） vs. 9.3% （7/75）, P=0.015）]. Heavy smoking [odds ratio （OR）, 1.89; 95% confidence interval （CI）, 1.74-2.05], hypertension （OR, 1.56; 95% CI, 1.48-1.65）, alcohol （OR, 1.37; 95% CI, 1.30-1.46）, type 2 diabetes mellitus （OR, 1.37; 95% CI, 1.25-1.50）, high-fat diet （OR, 1.35; 95% CI, 1.28-1.43）, and BMI〉24 kg/m2 （OR, 1.09; 95% CI, 1.03-1.17） were factors related to CAD in the young patients （all P〈0.05）. Total cholesterol （4.56_±1.46 mmol/L vs. 4.09_±1.00 mmol/L）, low-density lipoprotein cholesterol （2.38±1.11 mmol/L vs. 2.14±0.63 rnmol/L）, lipoprotein a （134.97±109.70 mg/L vs. 101.58±58.39 mg/L）, uric acid （359.89_±100.09 μmol/L vs. 336.75±94.36 μmol/L）, erythrocyte sedimentation rate （9.98± 12.19 ram/hour vs. 4.89_±4.92 mm/hour）, high-sensitivity C-reactive protein （3.42±4.39 mg/L vs. 2.80±_3.77 mg/L） and Big endothelin-1 （1.41±1.50 fmol/mL vs. 0.77_±1.13 fmol/mL） in plasma were significantly increased in the CAD group compared with the non-CAD group （all P〈0.05）. Conclusions Heavy smoking, hypertension, alcohol consumption, type 2 diabetes mellitus, high-fat diet and BMI〉24 kg/m2 were significantly related to CAD in patients aged ≤40, with heavy smoking presenting the highest OR. Metabolic syndrome and inflammation were also more common in young CAD patients than in non-CAD patients.

A nested case-control study of maternal-neonatal transmission of hepatitis B virus in a Chinese population

AIM:To examine the determinants of maternal-neonatal transmission of hepatitis B virus(HBV) METHODS:A nested case-control study was conducted in Changsha,Hunan,People's Republic of China from January 1,2005 to September 31,2006 To avoid potential maternal blood contamination,we collected vein blood of newborns immediately after birth and before initial hepatitis B vaccination to determine the HBV infection status of the newborn For each HBsAg-positive infant,one HBsAg-negative infant born to an HBsAg-positive mother was matched by hospital at birth(same),gender(same),and date of birth(within 1 mo) A faceto-face interview was conducted to collect clinical and epidemiological data Conditional logistic regression analysis was used to estimate the independent effects of various determinants on maternal-neonatal transmission of HBV RESULTS:A total of 141 HBsAg-positive infants and 141 individually matched HBsAg-negative infants were included in the final analysis Maternal first-degree family history of HBV infection,intrahepatic cholestasis,and premature rupture of membranes were risk factors for perinatal transmission of HBV,whereas systematic treatment and HBV immunoglobulin injections for mothers with HBV infection were protective factors for maternal-neonatal transmission of HBV,after adjustment for potential confounding factors CONCLUSION:For HBsAg-positive mothers,systematic treatment,HBV immunoglobulin administration,and controlling intrahepatic cholestasis and pregnancy complications may reduce the incidence of perinatal transmission of HBV.

Rationality and Risk Management of the Basic Old-age Insurance Fund Invested in the Capital Market

With the accelerated development of population aging, the pressure to pay for the future pension fund in our country is increasing. Affected by many factors, such as investment limits, inflation and interest rate cut, the rate of return on investment is very low. The introduction of the new policy allows the basic pension fund to enter the capital market, which is of great significance to improve the rate of return on investment, ease the pressure of capital gap, and promote the healthy development of the capital market. This paper makes a deep analysis of the rationality of the basic endowment insurance fund entering the market, and then puts forward some suggestions to avoid the risk of the pension market.

A polymorphism within ErbB4 is associated with risk for hepatocellular carcinoma in Chinese population

AIM:To investigate the association between hepatocel-lular carcinoma (HCC) susceptibility and a 12-bp inser-tion/deletion polymorphism (rs6147150) in the 3'UTR of ErbB4.METHODS:Using a case-control design,the rs6147150 genotypes in 270 patients with HCC and 270 healthy controls were determined by direct polymerase chain reaction and polyacrylamide gel electrophoresis.Logistic regression was used to analyze the association between the polymorphism and cancer risk.RESULTS:Computational modeling suggested that rs6147150 was located in the seed region of hsa-let-7c,a potential target sequence in ErbB4 3'UTR.Logistic re-gression analysis showed that,compared with individu-als homozygous for wild-type,heterozygotes [adjusted odds ratio (OR)=1.48,95% confidence interval (CI)= 1.03-2.17,P=0.034] and individuals homozygous for 12-bp del/del (OR=2.50,95% CI=1.37-4.56,P=0.001) were at significantly higher risk of HCC.Car-riers of the "del" allele of rs6147150 had a 1.59-fold increased risk for HCC (95% CI=1.22-2.07,P=0.003).CONCLUSION:rs6147150 may be associated with HCC risk,in part through let-7c-mediated regulation,and may be involved in the pathogenesis of HCC in Chi-nese populations.

Association of NOD1 and NOD2 genes polymorphisms with Helicobacter pylori related gastric cancer in a Chinese population

AIM:To investigate the association between the tag single nucleotide polymorphisms(TagSNPs) of NOD1 and NOD2 and the risk of developing gastric cancer.METHODS:We conducted a hospital-based case-control study including 296 incident gastric cancer patients and 160 gastritis controls.Eight TagSNPs in the NOD1 and NOD2 genes were selected from the Hapmap database using the haploview software and genotyped by the Sequenom MassArray system.The serum levels of anti-Helicobacter pylori(H.pylori) IgG were measured by enzyme-linked immunosorbent assay to indicate H.pylori infection.The odds ratios(OR) and 95% confidence intervals(CI) were calculated by unconditional logistic regression,including sex and age as confounding factors.RESULTS:The NOD1 rs2907749 GG genotype showed a decreased risk for gastric cancer(OR 0.50,95% CI:0.26-0.95,P = 0.04) while the rs7789045 TT genotype showed an increased risk(OR 2.14,95% CI:1.20-3.82,P = 0.01).An elevated susceptibility to gastric cancer was observed in the subjects with H.pylori infection and the NaOD1 rs7789045 TT genotype(OR 2.05,95% CI:1.07-3.94,P = 0.03) or the NOD2 rs7205423 GC genotype(OR 2.52,95% CI:1.05-6.04,P = 0.04).Haplotype analysis suggested that the distribution of AGT(rs2907749,rs2075820 and rs7789045) in NOD1 between the cases and control groups was significantly different(P corrected:0.04),and the diplotype AGT/AGT was associated with an elevated gastric cancer risk(OR 1.98,95% CI:1.04-3.79,P = 0.04).The association of the NOD1 rs7789045 TT genotype and the diplotype AGT/AGT was significant with H.pylori-related diffuse-type gastric cancer(OR 3.00,95% CI:1.38-6.53,P = 0.01;OR 4.02,95% CI:1.61-10.05,P < 0.01,respectively).CONCLUSION:Genetic polymorphisms in NOD1 and NOD2 may interact with H.pylori infection and may play important roles in promoting the development of gastric cancer in the Chinese population.

Assumptions Regarding the Development of Selected Europe 2020 Objectives in Terms of Public Finances in the Slovak Republic and the Czech Republic

This paper uses regression analysis and econometric modeling foundations to track public expenditures in the Slovak Republic and the Czech Republic （Fejesova, 2011） and their influences on the development of the following two targets of the Europe 2020 Strategy： to increase the employment of the selected population groups to a predetermined percentage level and to reduce the number of people at risk of poverty. In addition to the selection of monitored indicators, we included other indicators from the social sphere, which are funded by mandatory national public expenditure budgets and which are expected to have a positive development in terms of improving the demographic structure of the country--the unemployment rate and the number of live births.

Naturalization of Landscaping Woody Plant, Magnolia obovata Potentially Invasive Species

Magnolia obovata, a tree species native to Japan, is a traditional landscaping tree that has also been introduced to various countries. M. obovata individuals have recently emerged in non-planting areas in Korea, prompting us to investigate its distribution by establishing Dosolsan in an urban forest of Daejeon City as the target site. In order to determine its naturalization, the study explored the status of population growth by examining the diameter at breast height of the individuals, and diameter diminution quotient was calculated. Cores of the trees were collected, and the age distribution was estimated by regression analysis. Reproduction possibility was analyzed by verifying the flowerblooming and fruit-bearing. Spontaneous colonization was investigated in the other potential sites which have different location and environment, respectively.The diameter distribution showed a reverse J-shaped curve, and the diminution quotient was ≥ 1.8. The population was composed of different generations,thus confirming the growth of the population. The distributed M. obovata grew and flowered normally,and followed a normal life cycle. The same phenomenon was observed in other planting areas,residual forests in urban or rural areas, alluvial islands, and mountain forests. The continuous spread of M. obovata in new ecosystems may be attributable to its long-term distribution by birds, relatively fast growth, and maturity time. Investigations on the naturalization and spread of M. obovata in Korea, as well as in various countries, are warranted.

Correlates of women's environmental behaviors: a study in Pawe Woreda,Northwest Ethiopia

Available cross-country, macro-level evidence regarding gender differences in environmental behaviors shows women are more environmentally concerned and responsive than men.However, while such macro-level evidence helps understand patterns of women's environmental behaviors at a much broader level, it does not allow deeper insights into particular patterns at a single location or in much smaller areas. Tailor-made interventions needed to address livelihood and environmental strategies of poor rural women become meaningful if studies aim at revealing context specific, local variations in women's environmental behaviors. In this context, there is only little research for Ethiopia regarding what influences women's response to environmental problems. The objective of this research was to describe women's response to environmental problems in Pawe Woreda and examine the demographic, socioeconomic, and institutional correlates of this response, with particular emphasis to forest resources. Data were primarily obtained from a sample of 363 households in a multi-stage sample survey and were analyzed mainly using a multivariate logistic regression model. We found that all except one of the demographic and socioeconomic variables included in the model were found to be statistically significant correlates of woman's environmental response, but the institutional variable was not significantly associated with a woman's environmental response. However, the qualitative result for additional institutional issues revealed the importance of land tenure. Many of the results are in line with the existing literature.
