Objective To determine the efficacy of berberine in the treatment of non-alcoholic steatohepatitis ( NASH) , and to investigate the regulating effect on macrophage phenotype transformation in hepatic tissue on methionine -choline deficiency (MCD) diet induced NASH mice.Methods Fourty male C57BL/6 mice were randomly divided into 4 groups (10 mice per group): the normal group (fed with normal diet), the NASH model group (fed with MCD diet), rosiglitazone treatment group (30mg/kg) and berberine treatment group (150mg/kg).Drugs were adopted in the preventive intervention method for 2 weeks.The hepatic histopathological method was adopted to evaluate the drug therapeutic effect.The serum levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, and IL-10 were examined with ELISA method.M1 and M2 phenotype were detected by flow cytometry .Results The results showed berberine improved the degree of hepatic histopathology .Berberine not only reduced the level of TNF-α, but also increased the level of IL-10 in serum on NASH mice significantly ( P <0.05 ) . Flow cytometry data indicated that berberine decreased M 1 type macrophages and increased M 2 type macrophages in liver tissue .The ratio of M1/M2 was significantly decreased in berberine and rosiglitazone treated group ( P <0.01 ) .Conclusion Berberine may improve the hepatic pathological process in MCD diet induced NASH model possibly through modulating macrophage phenotype transformation , i.e.The ratio of M2 type is more than M1 type in hepatic tissue , and increasing anti-inflammatory cytokines .

Objective To investigate the potential relationship between initial 131Ⅰ uptake by lung metastases from differentiated thyroid cancer (DTC) and treatment outcomes. Methods From 1997 to 2009, 41 patients with DTC lung metastases were treated in the authors' department. 131Ⅰ whole body scan (WBS), serum Tg levels and other imaging results were analyzed to evaluate the therapeutic effects. Complete response (CR) or partial response (PR) was considered to be effective. The x2 test and correlation analysis were performed using SPSS 11.5 software package. Results 131 Ⅰ treatment was effective in 63% (26/41) patients with DTC lung metastases, CR in 8 patients and PR in 18 patients. In other 37% ( 15/41 ) patients, 131Ⅰ treatment was ineffective, including one case died of distant metastases. Patients with initial presence of 131Ⅰ lung uptake had higher effective rate than those with 131Ⅰ lung uptake during the second or later 131Ⅰ treatment (76% (22/29)vs33% (4/12),x2 =4.911, P=0.027). Also, significantly higher effective rate was found in patients with lung metastases alone than those with extra-pulmonary metastases (75% (24/32) vs 22% (2/9), x2 = 6. 312, P =0.012). However, the effective rate in patients with diffuse metastases was not significantly different from that in patients with focal metastases (67% (12/18)vs 61% ( 14/23), x2 =0. 146, P=0.702). The positive rate of initial 131Ⅰ uptake by lung metastases was higher in patients with total thyroidectomy than those with partial thyroidectomy (83% (24/29) vs 42% (5/12) ). Those positive rates in patients with papilary DTC and patients with follicular DTC were 72% (23/32) and 6/9, respectively. The surgical mode was correlated with the initial 131Ⅰ uptake by lung metastases (r = 0.411, P ＜ 0.05), but no correlation was found between the histological type and the initial 131Ⅰ uptake by lung metastases ( r = 0. 047, P ＞ 0.05 ). Conclusion Initial uptake of 131 Ⅰ by lung metastases alone is a favorable prognostic factor for DTC patients treated by131Ⅰ, and total thyroidectomy may be beneficial for initial 131Ⅰ uptake by lung metastases.

Objective To study the gene mutation of fibroblast growth factor receptor 3 (FGFR3) and p53 in bladder cancer tissue and to explore their relationship with tumor recurrence. Methods DHPLC and PCR direct sequence were used to detect the mutation of FGFR3 and p53 in BTCC (n=98) and normal bladder mucosa (n=10). Genomic DNA of 98 BTCC was extracted. The exon 5-8 of P53 and the exon 7, 10, 15 were amplification by PCR. The products of PCR was screened by DHPLC to detect the mutation of the production. The results of the FGFR3 and p53 mutation were analyzed by Kaplan-Meier method and no recurrence survival rate was tested by log rank test. All the analysis were aim to explore the clinical biological value of the mutation of FGFR3 and p53. Results Mutation of FGFR3 in BTCC (44. 9%) was higher than normal bladder mucosa(0, P<0.01). Mutation in T_a-T_1 was 75. 6%(33/45) ,T_2 -T_4 was 26. 6%C10/53). Mutation in G_1 was84. 6%(11/13),inG_2 was 61. 4% (27/44), in G_3 was 14. 6% (6/41), (P<0. 05). The mutation rate was lower with the higher of stage and grade. Mutation of p53 in BTCC (34. 6%) was higher than normal bladder mucosa (0%) (P<0. 01). Mutation in T_a - T_1 was 20. 0% (9/45), T_2 - T_4 was 47. 2%(25/53). Mutation in G_1 was G_1 7. 7%(1/13), in G_2 18. 2%(8/44),in G_3 58. 1%(25/41) , (P<0. 05). The mutation rate was higher in the higher stage and grade. Kaplan-Meier method results revealed that mutation of FGFR3 indicating a favorable prognosis while mutation of p53 indicating a poor prognosis. As to the analysis of genotype, the type of FGFR3mut/p53wt had a relative longer recurrent interval (P<0. 01). Conclusions Mutation of FGFR3 indicated a relative longer recurrent interval, which revealed a favorable prognosis of BTCC. Mutation of p53 indicated a relative shorter recurrent interval, which revealed a poor prognosis.

Objective To investigate and explore the awareness and willingness of breast cancer screening between Han and Mongolian women in Ordos, Inner Mongolia Autonomous Region, and to analyze the influence factors. Methods The patients answered investigation questionnaires face to face, and the content of questionnaire included demographic information, breast cancer awareness and relevant affecting factors on the awareness and willingness. Results 11162 (88.2 %) Han women and 1495 (11.8 %) Mongolian women were enrolled in the survey, with the average age of (45.4 ±7.1) years old and (45.4 ±6.8) years old. The education level (high school and above) of Han women was lower than that of Mongolian women [4456 women (40.0%) vs. 750 women (50.2%), χ2= 57.041, P< 0.001]. The Main way to delivery information on breast cancer screening in Han and Mongolian women was from their family members or friends [5002 women (44.9%) vs. 688 women (46.1%),χ2=40.699, P<0.001]. The proportions of never attending screening in the Han and Mongolian women were 41.7 % (4640 women) and 45.9 % (683 women), respectively (χ2=14.075, P=0.001). The breast self-examination rate of Han women were higher than that of Mongolian [71.1 % (7926 women) vs. 58.5 % (872 women), χ2= 98.466, P< 0.001]. According to logistics regression analysis, the cognitive level of women with high education level and breast disease history was higher (all P<0.001). Conclusions The cognitive level of breast cancer screening in Han women is better than that in the Mongolian, however, the overall level are low. It is necessary to strengthen the propaganda and education, and to encourage women to actively participate in breast cancer screening.

Hepatic sclerosing hemangioma (HSH) is a rare benign tumor that is considered fibrosis and hyaline change caused by degenerative changes of cavernous angioma, and changes in pathological features cause the changes in imaging features, making this atypical hemangioma easily misdiagnosed as primary or metastatic malignant tumor. Although there are many studies on the imaging findings of this disease, it is still difficult to diagnose and most patients underwent resection since it is misdiagnosed as malignant tumor. There is still a low rate of confirmed diagnosis before surgery. This article elaborates on the etiology, clinical manifestations and pathological features, imaging findings, diagnosis, and treatment of HSH, in order to provide a reference for the diagnosis and treatment of this disease.

OBJECTIVESTo investigate the prognostic significance of Omi/HtrA2 expression, and the correlation between Omi/HtrA2 and Hypoxia-inducible factor (HIF)-1α in primary hepatocellular carcinoma cells.

METHODSThe expression of HIF-1α and Omi/HtrA2 in 43 cases of hepatic carcinoma tissues were detected immunohistochemically. Follow-up data were obtained to perform the Kaplan-Meier survival analysis. The change of Omi/HtrA2 expression in HepG2 cell was measured after HIF-1α expression of HepG2 in vitro was regulated by Tet-on expression system.

RESULTSOmi/HtrA2 expression was correlated with lymph node metastasis and recurring within liver during 2 years. Statistical analysis estimation showed the cumulative survival rate of post-hepatectomy for the patients with the positive expression of Omi/HtrA2 was higher than that for other patients with the negative expression of Omi/HtrA2 (χ(2) = 6.13, P = 0.013). In the common paraffin-embedded specimen of hepatocellular carcinoma, most of the samples showing negative or weak positive HIF-1α immunopositivity showed moderate positive or strong positive Omi/HtrA2 immunopositivity, while most of the samples showing moderate positive or strong positive HIF-1α immunopositivity showed negative or weak positive Omi/HtrA2 immunopositivity. The mRNA expression intensity of Omi/HtrA2 was decreasing with the HIF-1α expression increasing, and the difference was statistically significant(F = 106.766, P < 0.01).

CONCLUSIONSOmi/HtrA2 may be an important prognostic marker for primary hepatocellular carcinoma. Omi/HtrA2 expression is reversely correlated with HIF-1α expression in hepatocellular carcinoma. During the apoptotic process Omi/HtrA2 participating in hepatocellular carcinoma cells, HIF-1α is involved in the controlling and regulating of Omi/HtrA2 expression.
