The aim of the study is to evaluate the effects of the single and mixed decoction of Thallus laminariae (kelp) and Glycyrrhiza glabra (licorice) on the metabolism and their difference. The mixed decoction of kelp and licorice and the single decoction were made and intragastrically administered to the SD rats. The effect on system metabolism, the toxicity of liver and kidney were assessed by GC-MS profiling of the endogenous molecules in serum, routine biochemical assays and histographic inspection of tissues from SD rats, separately. The mixed decoction of kelp and licorice induced more obvious pathological abnormalities in SD rats than a single decoction of kelp, while the extracts of licorice did not show any pathological change. Neither the mixed, nor the single decoction showed abnormal histopathology. After intragastric administration of extracts for 5 days, the mixed decoction induced a decrease of ALT (no significant change in the groups of single decoction) and an increase of BUN (so did the single decoction of kelp). Metabolomic profile of the molecules in serum revealed that the metabolic patterns were all obviously affected for the three groups, i.e., the mixed and single decoction of kelp and licorice. The rats given with the single decoction of kelp showed a similar pattern to that of the mixed decoction, indicating that the kelp primarily contributed the perturbation of metabolism for the mixed decoction. All three groups induced a decrease of branched chain amino acids, TCA cycle intermediates and glycolysis intermediates (e.g., pyruvic acid and lactic acid) and an increase of 3-hydroxybutyric acid. Kelp decoction showed stronger potential in reducing TCA cycle intermediates and glycolysis intermediates than the other two groups, while the levels of branched chain amino acids were the lowest after licorice extracts were given. These results suggested that the effect of the mixed decoction on metabolism was closely associated with both kelp and licorice. The continuous administration of single decoction of kelp and the mixed decoction of licorice and kelp resulted in pathological abnormalities in kidney of SD rats. The mixed decoction of kelp and licorice distinctly perturbed sera molecules and hence system metabolism, which showed associated with those of kelp and licorice. Although the metabolic effect was associated with both kelp and licorice, the results suggested kelp contributed to it primarily.

OBJECTIVETo study the clinicopathologic features, diagnostic criteria, differential diagnosis and treatment options of ovarian steroid cell tumor, not otherwise specified (NOS).

METHODSLight microscopy and immunohistochemical study was carried out in 8 cases of ovarian steroid cell tumor, NOS. The literature was reviewed.

RESULTSThe 7 cases of benign ovarian steroid cell tumor, NOS were composed mainly of polygonal cells with granular eosinophilic cytoplasm and larger cells with vacuolated cytoplasm. They resembled the architecture of normal adrenal gland, with formation of cell nests and trabeculae. The single case of malignant ovarian steroid cell tumor had evidence of significant cellular pleomorphism, haemorrhage and coagulative tumor necrosis. The mitotic count measured about 7 per 10 high-power fields. Immunohistochemical study showed that the tumor cells expressed calretinin and alpha-inhibin. Differential diagnosis included oxyphilic granulosa cell tumor, thecoma, Sertoli cell tumor and clear cell carcinoma. The treatment options of benign ovarian steroid cell tumor, NOS was local excision or ipsilateral salpingo-oophorectomy, while the malignant counterpart should be treated with a combination of surgery and chemotherapy, including administration of GnRH agonist.

CONCLUSIONSOvarian steroid cell tumor, NOS, is the most common type of ovarian steroid cell tumors. Most of which are associated with a benign clinical outcome. Immunohistochemistry is an important adjunct for diagnosis. The treatment options of ovarian steroid cell tumor, NOS depend on its malignant potential.

Objective:To analyze therapeutic effect of amiodarone combined RAS inhibitors on hypertensive patients with atrial fibrillation(AF),and its influence on serum levels of uric acid(SUA)and silent information regulator 2-related enzymes 1(SIRT1).Methods:A total of 186 hypertensive patients with AF were selected from our hospital. They were randomly and equally divided into amiodarone group(group A),amiodarone + telmisartan group(A+T group)and amiodarone + ramipril group(A+ R group).Left atrial diameter(LAD),P wave dispersion(Pd),lev-els of high sensitive C reactive protein(hsCRP),brain natriuretic peptide(BNP)and SUA,SIRT1 mRNA and pro-tein expression and blood pressure variability(BPV)were observed and compared among three groups before and 45d after treatment.Results:Compared with before treatment,there were significant improvement in all index ex-cept SUA after treatment in three groups,P=0.001 all;compared with group A after treatment,there were signif-icant reductions in 24hSBPV[(0.112 ± 0.022)vs.(0.092 ± 0.020)vs.(0.091 ± 0.021)],24hDBPV[(0.143 ±0.031)vs.(0.130 ± 0.040)vs.(0.129 ± 0.039)],levels of hsCRP[(8.3 ± 0.3)mg/L vs.(5.3 ± 0.6)mg/L vs. (3.6 ± 0.4)mg/L],BNP[(64.9 ± 9.4)ng/dl vs.(61.1 ± 7.6)ng/dl vs.(58.2 ± 8.3)ng/dl]and SUA[(498.85 ± 89.54)μmol/L vs.(298.54 ± 56.12)μmol/L vs.(278.32 ± 54.09)μmol/L],SIRT1 mRNA[(2.20 ± 0.34)%vs.(1.87 ± 0.30)% vs.(1.76 ± 0.31)%]and protein[(29.54 ± 8.12)% vs.(26.31 ± 7.43)% vs.(23.21 ± 6.90)%]expression in A+T group and A+ R group,P<0.05 or <0.01. Compared with group A,there were sig-nificant rise in Pd[(39.3 ± 4.2)ms vs.(40.9 ± 4.1)ms,(41.2 ± 5.1)ms],and significant reduction in LAD [(37.8 ± 3.4)mm vs.(35.1 ± 4.6)mm,(35.7 ± 4.5)mm]in A+T group and A+R group,P<0.05 or <0.01. Conclusion:Amiodarone combined RAS inhibitors can significantly improve blood pressure variability,and reduce inflammatory factor,SUA and serum SIRT1 level in hypertensive patients with AF.

Objective:To detect the expression of Myc-induced nuclear antigen 53 (Mina53) and liver tissue >5 cm from the edge of the tumor (LTM5), and analyze its relationship with tumorigenesis, clinicopathological characteristics, and patient survival and prognosis in hepatocellular carcinoma (HCC).Methods:The expression levels of Mina53 mRNA and protein in 18 pairs of fresh HCC and LTM5 were assessed by qRT-PCR and Western blot, respectively. The expression of Mina53 in 284 pairs of HCC and LTM5 sample was determined by immunohistochemistry. Paired-sample t-test was used for the comparison of measurement data among groups, and heterogeneity of variance was tested using Wilcoxon rank-sum test. χ2 test was used for the comparison of measurement data among groups. Kaplan-Meier method and log-rank test were used for survival analysis. Cox regression model was used for single factor and multi factor analysis. Results:The relative expression levels of Mina53 mRNA and protein in 18 fresh HCC tissues were significantly higher than those in LTM5 tissues (mRNA: -4.41 ± 1.48 and -5.93 ± 1.65, t = 3.100, P = 0.007; protein: 1.12 ± 0.29 and 0.46 ± 0.21, t = 10.616, P < 0.001). The relative expression level of Mina53 in 284 HCC tissues was higher than that of LTM5 ( z = -18.739, P < 0.001). The expression level of Mina53 was associated with tumor size ( χ2 = 5.474, P = 0.019), vascular invasion ( χ2 = 8.965, P = 0.003), pathological grade ( χ2 = 12.006, P = 0.002), and TNM stage ( χ2 = 16.686, P < 0.001). The overall postoperative survival time and disease-free survival time of patients with high expression of Mina53 (28.5 months and 22.7 months, respectively) were shorter than those with low expression (33.0 months and 31.8 months, respectively) ( P < 0.05) in HCC. Cox multivariate regression analysis showed that Mina53 and multiple tumors were independent prognostic factors affecting the overall postoperative survival time and disease-free survival time of HCC patients ( P < 0.05). Conclusion:Mina53 may play an important role in the occurrence of HCC and participate in the process of tumor growth as well as invasion and metastasis. The high expression of Mina53 signifies that the patient has a poor prognosis and thus can be used as a potential marker for judging the prognosis of HCC patients.

Objective To detect the expression of EIF5A2 in hepatocellular carcinoma(HCC) and to explore its relation with clinicopathological characters and prognosis of HCC patients. Methods The expression of EIF5A2 mRNA and protein in 12 pairs of fresh HCC and corresponding non-tumor tissues adjacent to the cancer was examined by qRT-PCR and Western blot. The expression level of EIF5A2 in 284 pairs of HCC and adjacent non-tumor tissues was detected by IHC staining. Then we analyzed between EIF5A2 expression and clinical pathological parameters and prognosis of HCC patients. Results The relative expression levels of EIF5A2 mRNA and protein in fresh HCC tissues were significantly higher than those in the corresponding adjacent non-tumor tissues (t=5.305, P=0.0003; t=10.120, P < 0.001); EIF5A2 expression in 284 HCC tissues was significantly higher than that in the corresponding adjacent non-tumor tissues (z=-12.186, P < 0.001). The expression of EIF5A2 was significantly correlated with tumor size (χ²=13.079, P < 0.001), tumor multiplicity (χ²=4.589, P=0.032) and differentiation degree (χ²=4.844, P=0.028). The 3- and 5-year overall survival time and disease-free survival time of the patients with high expression of EIF5A2 were significantly shorter than those with low expression of EIF5A2 (P < 0.001). EIF5A2 was an independent prognostic factor affecting the 3- and 5-year overall survival time and disease-free survival time of HCC patients (P < 0.05). Conclusion The up-regulation of EIF5A2 expression may be related with the occurrence and development of hepatocellular carcinoma. The high expression of EIF5A2 is an independent influence factor for poor prognosis and EIF5A2 can be used as a potential molecular marker for predicting the prognosis of HCC patients.

OBJECTIVETo extract tumor interstitial fluid (TIF) from MKN-45 gastric cancer which is similar to "muddy phlegm" in Chinese medicine and observe influences of MKN-45 tumor interstitial fluid (MKN-45 TIF) intervention on metastasis of gastric cancer and on the expressions of vascular endothelial growth factor (VEGF), kinase insert domain containing receptor (KDR), epithelial-cadherin (E-cad), cyclooxygenase-2 (COX-2), intercellular adhesion molecule-1 (ICAM-1) and telomerase genes and proteins in primary tumor tissue.

METHODSAn MKN-45 tumor-bearing model was established in 50 nude mice. The modeled animals were equally randomized to 5 groups: the simple tumor-bearing group (model group), the normal saline (NS) via tail vein injection (i.v.) group (NS i.v. group), MKN-45 TIF i.v. group (TIF i.v. group), NS intraperitoneal injection (i.p.) group (NS i.p. group), and MKN-45 TIF i.p. group (TIF i.p. group). The TIF and NS intervention groups received injection (i.p. or i.v.) of MKN-45 TIF or NS twice a week, 0.2 mL at a time. After 8 weeks, the primary tumors were removed, weighed and HE stained to observe tumor metastasis. The primary tumor tissues were analyzed by immunohistochemistry and real-time quantitative PCR to detect expressions of VEGF, KDR, E-cad, COX-2, ICAM-1, and telomerase genes and proteins in different groups.

RESULTSThere were significant differences in tumor weight between TIF intervention groups and the model and NS intervention groups. Tumor metastasis was observed in all 5 groups, but the tumor metastasis rate in TIF intervention groups was significantly higher than those in the model and NS intervention groups. The gene and protein expressions of gastric cancer-related factors VEGF, KDR, COX-2, ICAM-1 and telomerase were unregulated while the gene and protein expressions of E-cad were downregulated in TIF intervention groups.

CONCLUSIONSTIF promotes tumor growth, invasion and metastasis of gastric cancer. These findings provide preliminary experimental clues for verifying the hypothesis of "tumor-phlegm microenvironment".
