Objective To investigate the correlation between ultrasonographie classification, age and lesion in female. Methods One thousand two hundred and eight patients with 2416 mammary gland were comfired by pathologic findings, including 132 benign lesion and 54 malignancy lesion. According various sonographic appearances in the mammary gland structure and involution grade, the mammary glonds were classified into glandular,fibroglandular and fatty types. A single mammary gland is statistic unit. Results To follow age growth, the proportion of glandular type was decrease, 61.7% in under 30 years of age,31.5% in 30-39 years of age,15.3% in 40-49 years of age,8.6% in 50-59 years of age,4.5 in over 60 years of age. To follow age growth, the proportion of fatty type was higher, 1.6 % in under 30 years of age, 5.80% in 30-39 years of age,5.5% in 40-49 years of age,10.8% in 50-59 years of age,38.6% in over 60 years of age. Before 60 years of age, to follow age growth, the proportion of fibroglandular type was higher, which achieved the peak value (79.2%) in 40-49 years and last to 50-59 years of age (80.6%) ,but it was decrease to 56.9% after 60 years of age. There was significant difference of the proportion in any age(P=0.000).The proportion of the benign lesion no difference in three categories. The proportion of malignancy lesion (6.23%, 16/257 mammary gland)in fatty type was higher than that in fibroglandular type (2.18%,37/1698 mammary gland) which was significant difference(P=0.000). There was no malignancy lesion in glandular type. Conclusions Significant correlation were present between uhrasonographic classification, age and malignancy lesion, no significant correlation were found between uhrasonographic classification, age and benign lesion.

There is controversy regarding the roles of Ureaplasma urealyticum (U. urealyticum) colonization in the development of bronchopulmonary dysplasia (BPD). This study explored the association between U. urealyticum and bronchopulmonary dysplasia at 36 weeks post-menstrual age (BPD36). Studies published before December 31, 2013 were searched from Medline, Embase, Ovid, Web of Science, and Cochrane databases, with the terms "Ureaplasma urealyticum", "chronic lung disease", or "BPD36" used, and English language as a limit. The association between U. urealyticum colonization and BPD36 was analyzed with RevMan 4.2.10 software, using the odds ratio (OR) and relative risk (RR) for dichotomous variables. Out of the enrolled 81 studies, 11 investigated the BPD36 in total 1193 infants. Pooled studies showed no association between U. urealyticum colonization and subsequent development of BPD36, with the OR and RR being 1.03 (95% CI=0.78-1.37; P=0.84) and 1.01 (95% CI= 0.88-1.16, P=0.84), respectively. These findings indicated no association between U. urealyticum colonization and the development of BPD36.

Objective To explore the association between estimated glomerular filtration rate (eGFR) and metabolic syndrome (MS) . Method The data were from the China Health and Nutrition Survey (CHNS) . The data included the physical measurement and biochemical markers of adults of CHNS in 2009. Finally, 7309 individual observations were included in the analysis. Results According to the criteria of MS, 2034 patients were diagnosed as MS, and the prevalence was 27.83%. There were 1508 (74.14%) patients had moderate reduced eGFR in MS patients, and 3357 individuals (63.64%) were diagnosed as moderate reduced eGFR in non-MS patients. There was significant difference between two groups (X2=72.13, P<0.001) . The incident of moderate reduced eGFR was positively associated with fasting plasma glucose (OR=1.22, 95%CI: 1.06-1.42, P=0.005), triglyceride (OR=1.21, 95%CI: 1.05-1.38, P=0.005) and negatively associated with HDL-C (OR=1.23, 95% CI: 1.06-1.41, P=0.004) . Conclusion The MS and its components might be the influencing factors of developing moderate reduced eGFR, and the screening should be focused on the population with MS.

OBJECTIVETo explore risk factors of nonalcoholic fatty liver disease (NAFLD) in men in order to provide a theoretical basis for developing more effective NAFLD prevention and control strategies.

METHODSOne-hundred-and-two male patients (37.3+/-11.4 years old) hospitalized with NAFLD at the Dongnan Affiliated Hospital of Xiamen University between January 2009 and December 2010 were enrolled in the study, along with 23 age-matched healthy men (34.4+/-16.7 years old) to serve as the control group. The correlation(s) of body mass index (BMI; overweight defined as more than or equal to 22.717 kg/m2), waist circumference (WC), waist-to-hip ratio (WHR; central obesity defined as more than or equal to 0.866), fasting plasma glucose (FPG), triglyceride (TG), and total cholesterol (TC) with NAFLD was analyzed by univariate and multivariate logistic regression analyses. Receiver operating characteristic (ROC) curves were used to select proper thresholds for classification.

RESULTSBMI, WC, WHR, FPG, TG, and TC were significantly different between the cases and controls (P less than 0.01). BMI, WC, WHR, TG and TC were identified as risk factors of NAFLD in these male cases (P less than 0.01). Relative to WC, TG and TC, both BMI and WHR had significant predictive value for NAFLD (odds ratio (OR) = 10.819 and 10.588, respectively). In addition, BMI had the highest diagnostic value for the prediction of NAFLD (area under the curve (AUC) = 0.931) followed by WHR (AUC = 0.879).

CONCLUSIONBMI, WC, WHR, TG, and TC are risk factors of NAFLD in Chinese men. BMI and WHR are effective anthroposomatology indices of NAFLD and may be useful factors on which to base future prevention and early diagnosis strategies for NAFLD in males.

OBJECTIVEThis study examined the effects of PI3K inhibitor LY294002 on the differentiation of mouse preadipocytes and the expression of CCAAT enhancer binding protein α (C/EBPα) and peroxisome proliferation activated receptor γ (PPARγ), in order to study the possible roles of insulin receptor substrate (IRSs)/PI3K signal pathway in the differentiation of preadipocytes.

METHODSThe mouse 3T3-L1 cells were cultured normally and divided into experimental and control groups. 3T3-L1 cells in the experimental group were treated with PI3K inhibitor LY294002 (25 μmol/L) and those in the control group were treated with DMSO culture medium. 3-isobutyl-1-methylxanthine (IBMX) (0.5 mmol/L), dexamethasone (10-6 mol/L) and insulin (5 μg/mL) were used to induce the differentiation of 3T3-L1 preadipocytes in both groups. Before culture, and 2, 4 and 8 days after culture, the cells were collected to detect the expression of C/EBPα and PPARγ by real-time PCR and Western blot assays. The lipid droplets of 3T3-L1 preadipocytes were observed by oil-red O staining.

RESULTSPI3K inhibitor LY294002 did not affect the expression of C/EBPα and PPARγ in un-induced 3T3-L1 preadipocytes (P>0.05), but decreased the expression of C/EBPα and PPARγ during the in vitro induced differentiation of 3T3-L1 preadipocytes compared with the control group (P<0.05 or 0.01). The lipid droplets count was greatly reduced by LY294002.

CONCLUSIONSPI3K inhibitor LY294002 can inhibit the differentiation of mouse 3T3-LI preadipocytes and the expression of C/EBPα and PPARγ in the differentiation of 3T3-LI preadipoeytes, suggesting that IRSs/PI3K signal pathway may play an important role in the differentiation of 3T3-L1 preadipocytes by regulating the expression of C/EBPα and PPARγ.

OBJECTIVETo investigate the correlation between nonalcoholic fatty liver disease (NAFLD) and three anthropometric indices, namely waist to hip ratio (WHR), body mass index (BMI) and waist to height ratio (WHtR).

METHODSThis retrospective case-control study involved 77 NAFLD patients and 50 patients without such disease, and their data of the 3 anthropometric indices were collected. Risk correlation analysis and Mantel-Haenszel chi-square test were used for correlation analysis.

RESULTSNAFLD was significantly correlated to WHR (chi(2)(MH)=59.609, P<0.001; odds ratio=30.522, 95% CI 12.815-72.695), WHtR (chi(2)(MH)=45.316, P<0.001; odds ratio=21.037, 95% CI 8.665-51.072) and showed a dose-response relationship with BMI (chi(2)=25.017, P<0.001).

CONCLUSIONThese results support a close correlation between NAFLD and the 3 anthropometric indices, indicating that BMI, WHR and WHtR can be significant predictors of NAFLD and have potential value for evaluating and predicting NAFLD.
