Relative analysis of OPN and its related signal molecules in hepatocellular carcinoma / 中华肝脏病杂志

Osteopontin (OPN) has close relationship with metastasis in hepatocellular carcinoma but its downstream signal pathways have not been well defined in hepatocellular carcinoma. The object of this study is to identify the associated signal pathways in human HCC tissues. The expressions of OPN, intergrin aV, CD44v6, P-FAK, FAK, P-Src, Src, P-ERK and P-AKT were assayed using TMA analysis. The relationship of OPN with P-ERK, P-Src and P-AKT were explored and the role in HCC metastasis was analysed. The expression levels of OPN, intergrin aV, CD44v6, P-FAK, P-Src, Src, P-ERK and P-AKT in HCC tissue were significantly higher than that in normal tissue (P value is less than 0.05). No significant difference was found between the expression levels of FAK in HCC tissue and normal tissue (P value is more than 0.05). OPN expression was significantly associated with Integrin av (P value is less than 0.01), CD44V6 (P value is less than 0.01) and P-ERK (P value is less than 0.05) but not with P-Src, P-FAK and P-AKT (P value is more than 0.05). The expressions of P-FAK (P value is less than 0.05), P-Src (P value is less than 0.01) and P-AKT (P value is less than 0.05) were significantly associated with Integrin av and the P-FAK expression was also significantly associated with CD44V6 (P value is less than 0.01). OPN promotes HCC metastasis though Integrin av/CD44V6/MAPK pathway in human HCC.

The effect of birth weight and early growth on body fat composition and insulin sensitivity / 中华预防医学杂志

<p><b>OBJECTIVE</b>To investigate the effect of birth weight and early growth on body fat composition and insulin sensitivity.</p><p><b>METHODS</b>The birth and growth data of 258 children of 6 to 7 years old in Guangzhou were collected from Jun.2009 to Feb. 2010. Physical and laboratory examination were preformed, which included body weight, body height and body fat composition index (body mass index (BMI), percentage of body fat (PBF), waist circumference to height ratio (WtHR), etc). Fasting blood glucose and insulin were measured. The homeostasis model assessment model for insulin resistance index (HOMA-IR) was calculated. According to birth weight, the children were divided into three groups from light to heavy: BW-I, BW-II, BW-III group. Then according to change in weight SDS between 0 and 36 months, the children were divided into three groups: changers up (CU), non-changers (NC), changers down (CD) group. The effect of birth weight and early growth on body fat composition and insulin sensitivity were analyzed.</p><p><b>RESULTS</b>Change in weight SDS between 0 and 36 months was higher in BW-I group (1.06 ± 1.29) than in the BW-II group (-0.19 ± 0.94) and BW-III group (-0.10 ± 1.20) (all P values < 0.01). Birth weight of the CU group ((2.90 ± 0.47) kg) was lower than that of the NC group ((3.22 ± 0.34) kg) and the CD group ((3.57 ± 0.37) kg) (all P values < 0.01). The body fat composition index of BMI, PBF and WtHR were higher in the BW-III group ((16.35 ± 2.13) kg/m(2), (17.03 ± 5.88)%, (0.479 ± 0.033)) than in the BW-I group ((15.46 ± 2.06) kg/m(2), (14.06 ± 5.25)%, (0.459 ± 0.032)) and BW-II group ((15.47 ± 1.58) kg/m(2), (14.09 ± 5.01)%, (0.460 ± 0.025)) (P < 0.01), while there was no significant difference between the BW-I group and the BW-II group (P > 0.05). The body fat composition index of BMI, PBF and WtHR were higher in the CU group ((16.44 ± 2.20) kg/m(2), (16.51 ± 5.78)%, (0.473 ± 0.034)) than in the NC group ((15.62 ± 1.74) kg/m(2), (14.49 ± 5.30)%, (0.463 ± 0.030)) and the CD group ((15.26 ± 1.85) kg/m(2), (14.24 ± 5.54)%, (0.462 ± 0.031)) (all P values < 0.05). In the CU group, BMI, PBF and WtHR were higher in the BW-III-CU group ((18.76 ± 2.56) kg/m(2), (22.19 ± 8.28)%, (0.512 ± 0.029)) than in the BW-I-CU group ((16.04 ± 2.14) kg/m(2), (15.54 ± 5.28)%, (0.467 ± 0.034)) and BW-II-CU group ((16.70 ± 1.36) kg/m(2), (17.12 ± 4.44)%, (0.474 ± 0.017)) (all P values < 0.05), while there was no significant difference between the BW-I-CU group and the BW-II-CU group (P > 0.05). HOMA-IR was higher in the CU group (1.27 ± 0.44) than in the NC group (1.08 ± 0.31) and the CD group (1.00 ± 0.36) (all P values < 0.01). In the CU group, HOMA-IR was higher in the BW-III-CU group (1.69 ± 0.48) than in the BW-I-CU group (1.21 ± 0.41) and the BW-II-CU group (1.27 ± 0.44) (all P values < 0.01), while there was no significant difference between the BW-I-CU and BW-II-CU group (P > 0.05).</p><p><b>CONCLUSION</b>According to birth weight tertile, both lower birth weight individuals with more weight change-up growth postnatal early and higher birth weight individuals had greater body fat composition in childhood. They were high-risk people of insulin resistance.</p>

Therapeutic efficacy and prognostic factors of sorafenib treatment in patients with unresectable primary hepatocellular carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and analyze the prognostic factors of sorafenib treatment in patient with unresectable primary hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>During the period from December 2005 to March 2009, 50 patients with unresectable primary HCC of Child-Pugh status A were treated with sorafenib (400 mg, Bid). The tumor response was evaluated with CT or MRI imaging every 6 - 8 weeks according to the RECIST criteria. The overall survival (OS) and time to progression (TTP) were defined as the time from administration of sorafenib to the death or the last follow up and were evaluated by Kaplan-Meier method.</p><p><b>RESULTS</b>There was no PR or CR, but 28 patients (56.0%) achieved stable disease. The median follow up time was 15 months with a median OS of 14 months and median TTP of 4 months. The common adverse events were dermal reaction (68.0%, 34/50), diarrhea (52.0%, 26/50), hypertension (4.0%, 2/50), hair loss (14.0%, 7/50), myelosuppression (16.0%, 8/50), and liver dysfunction (20.0%, 10/50). However, most of the drug-related adverse events were grade I-II and reversible. The patients with lower tumor burden and without distant metastasis had better prognosis.</p><p><b>CONCLUSION</b>Soafenib is effective for unresectable primary HCC with tolerable toxicity. Tumor stage is a predominant prognostic factor.</p>

Relationship between epithelial-mesenchymal transition and lung metastasis in hepatocellular carcinoma / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the relationship between epithelial mesenchymal transition (EMT) and lung metastasis in hepatocellular carcinoma.</p><p><b>METHODS</b>There were 100 patients who underwent surgical resection of hepatocellular carcinoma between January 2000 and March 2004. They were classified with non-distance metastasis and lung metastasis depend on the close following up till March 2007. Their hepatocellular carcinoma specimens were retrospectively examined for EMT markers (E-cadherin, Vimentin, Fibronectin) with immunochemistry staining in tissue microarray.
