Objective To study the relationship between the expression level of human telomerase reverse transcriptase (hTERT) protein and telomerase activity as well as its clinical significance in hepatocellular carcinoma (HCC). Methods Immunohistochemical SP method was employed to detect hTERT protein expression in 52 cases of HCC and paired adjacent tumor tissues, and telomerase activity was examined in these samples with telomeric repeat amplification-ELISA. Results The positive rates of hTERT protein expression and telomerase activity in HCC were 86.5%(45/52) and 80.8%(42/52), respectively, which were significantly higher compared with the adjacent tumor tissues(P

AIM: To investigate the expression of transcription factor GATA-3 gene in the bone marrow stromal cells (BMSCs) from patients with aplastic anemia (AA) and normal controls. METHODS: The expression of GATA-3 gene was analyzed by using RT-PCR-ELISA in BMSCs from 34 normal cases and 9 cases with AA. The standardized semi-quantitative expression level of GATA-3 gene in BMSCs from patients with AA was compared with normal controls. RESULTS: The expression of GATA-3 gene was detected in BMSCs from both normal controls and the cases with AA. The expression level of GATA-3 gene in BMSCs from AA was significant higher than that from the normal controls (P

AIM: To investigate the expression of SCL (stem cell leukemia) gene in bone marrow stromal cells (BMSCs) and bone marrow hematopoietic cells from patients with aplastic anemia (AA) and normal individuals. METHODS: Bone marrow stromal cells from AA (9 cases) and normal individuals (33 cases) were amplified by long-term in vitro culture. The adherent and nonadherent cells were collected respectively. RT-PCR-ELISA assay was then performed to detect the expression of SCL gene and the housekeeping gene ?_2 microglobulin (?_2M). The expression ratio of SCL gene were analyzed and its expression level was normalized by ?_2M gene acting as an internal calibration for the purpose of semi-quantitative analysis. RESULTS: The expression ratio of SCL gene was lower in BMSCs from AA (22.2%) than that in normal controls (69.7%, P

One hundred and seventy-one cases of hyperlipidemia were treated by moxibustion on Shenque (CV 8) and bilateral Zusanli (ST 36). After moxibustion, the blood-lipid contents of the patients with hyperlipidemia of various types were all lower than those before moxibustion.There was a significant difference between them. It is indicated that moxibustion on Shenque (CV 8) and bilateral Zusanli (ST 36) had the functions of reinforcing the spleen and kidney,warning yang, removing the stasis and treating both the principal and the secondary aspects of a disease for hyperlipidemia, which embodied the advantage of the function of regulating organism of moxibustion. The treatment by regulating can mobilize the regulating function of self to get the benign and bi-directional regulating effect for the various indexes of lipid metabolism and reach the intention of lowering blood-lipid.

Objective To explore the effect of invasion and migration of hepatocellular carcinoma (HCC) endothelial cells (TECs) affected by overexpression of microRNA-3178 (miR-3178) through the transfection of miR-3178 mimic.Methods Real-time polymerase chain reaction (Real-time PCR) was used to identify differential expression of miR-3178 in normal hepatic sinusoidal endothelial cells (HSECs) and HCC TECs.Furthermore,HCC TECs were divided into 3 groups:control (CON) group,miRNA-3178 upregulation (Mimics,up-regulation of miR-3178 expression was achieved using miR-3178 mimics transfected into HCC TECs) group and negative control (NC,negative control sequence was transfected into HCC TECs) group.RT-PCR was used to detect expression of miR-3178 in HCC TECs before and after transfection.Transfection efficiency was observed by using an inverted fluorescence microscope.HCC TECs invasionand migration were measured by matrigel invasion and transwell migration assay.EGR3 protein expression of HCC TECs were identified by Western blotting analysis.EGR3 mRNA expression of HCC TECs were identified by RT-PCR analysis.Results The results of RT-PCR showed that miR-3178 was significantly down-regulated in HCC TECs compared to HSECs (P ＜0.05),and expression of miR-3178 was significantly increased after the transcienttransfection (P ＜ 0.05).The transfection efficiency in HCC TECs was morethan 90％.Number of migrated and invaded cells and in miR-3178 group was significantly less than those in other groups.Target gene prediction software showed EGR3 was a possible candidate target.Transfection of miR-3178 mimic significantly decreased the mRNA and protein expression levels of EGR3.Conclusion MiR-3178 was downregulated in HCC TECs and overexpression of miR-3178 can specifically inhibit migration and invasion of HCC TECsin vitro through inhibiting EGR3 expression,thus,miR-3178 might be a critical targeted therapy strategv for HCC.

Objective To study the dietary nourishment of adult patients with leukemia and compare acute leukemic patients with chronic leukemic patients. Methods Adopting dietary review of 24 hours and seven consecutive days of dietary records method to obtain the food category and quantity of 122 patients with acute leukemia and 10 patients with chronic leukemia. Using statistic software SPSS11.0 to calculate the patients'intake of various kinds of nutfiments. and the difiences between acute and chronic leukemic patients were analyzed. Results The rate of most ontrients of patients'intake reaches RNI/AI is lower,especially vitamin A,vitamin C and caleium.There's a tendency that intake diet,energy and nourishments of acute leukemic patients is lower than that of those chronic leukemic patients. Conclusion There is a tendency of unbalanced dietary intakes in leukemic patients.including the low intakes.There is the tendency that nutritional status of acute leukemic patients iS poorer than that of chronic leukemic patients.
