Objective This study analyzes the expression and clinical significance of Gli1 and Gli3 proteins in hepatocellular carcinoma.Methods 36 patients with hepatocellular carcinoma were studied.The expressions of Gli1 and Gli3 in the carcinoma and adjacent non-tumor tissues were detected with immunohistochemical assay,and their correlations with clinicopathological factors were statistically analyzed.Results Expression rates of Gli1 in hepatocellular carcinoma and adjacent nontumor tissues were 75 ％ and 36.1％,respectively.Expression rates of Gli3 in hepatocellular carcinoma and adjacent non-tumor tissues were 58.3％ and 30.6％,respectively.Expression rates of Gli1 and Gli3 in hepatocellular carcinoma were significantly higher than in adjacent non-tumor tissues (P＜0.05),and a positive correlation was found between the expression of Gli1 and Gli3 (r=0.423,P＜0.05).There was no association between the expression of Gli3 and clinicopathological factors such as age,tumor size,tumor differentiation and lymphatic metastasis.The expression of Gll1 was not related witha patient's age and tumor size,hut there were significant associations with tumor differentiation and lymphatic metastasis.Conclusions Therefore,the expression rate of Gli1 was positively correlated with tumor malignancy,which makes the detection of Gli1 and Gli3 valuable for the diagnosis and prognosis of hepatocellular carcinoma.

AIM: To investigate the influences of native and oxidized lipoprotein(a) on human arterial smooth muscle cell (SMC) proliferation, change of intracellular free calcium concentration ([Ca 2+ ] i) and the protective effect of sodium ferulate(SF). METHODS: Lp(a) was oxidized by Cu 2+ and the extent of oxidation was assessed by the MDA content.Human SMC were incubated in culture media with SF for 12 h, then exposed to Lp(a) and oxidized-Lp(a), respectively. MTT colorimetry and flow cytometry were used to evaluated the proliferation of SMC and flurorescent indicator Fura-2/AM was used to determined [Ca 2+ ] i. RESULTS: ox-Lp(a) significantly promoted proliferation of SMC and increased[Ca 2+ ] i compared with Lp(a). SF(40,80 mg/L) remarkedly inhibited SMC proliferation and decreased the rising of [Ca 2+ ] i induced by ox-Lp(a) in a dose-dependent manner, but no effect on SMC proliferation and the increase in [Ca 2+ ] i induced by Lp(a).CONCLUSION: ox-Lp(a) induces the strong growth-promoting effect in SMC through increasing in [Ca 2+ ] i, which might be one of the cellular mechanisms responsible for the higher atherogenic potential of ox-Lp(a) compared with Lp(a), and this process can be prevented by inhibiting of oxidation by SF.

Objective To explore the Influence of different health education approaches to standard anticoagulation of non-valvular atrial fibrillation. Methods 400 patients with NVAF were randomly divided into the research group (n=200) and the control group (n=200). Baseline clinical information was recorded. Both groups were given regular education and treatment. The control group was randomly divided into two subgroups. One subgroup (patients or/and family members) was given knowledge lectures of atrial fibrillation, atrial fibrillation anticoagulant, and application of warfarin. The other was given the knowledge through booklets. Standard anticoagulation fulfillment rate, ischemic stroke, other events of artery embolism, major bleeding, minor bleeding and death in the two groups were observed after 1 year. The cost for different education approaches was also compared between the 2 subgroups. Results (1)In the research group, standard anticoagulation fullfillment rate (40.53%) was higher than that of the control group(15.96%) (P<0.01). The rate of ischemic stroke (2.63%) was also lower than the control group (4.49%) (χ2=4.49, P<0.05). The death rate was lower in the research group than those in the control group, but minor bleeding rate was higher, without statistically significance (P>0.05).Other artery embolism rate , major bleeding, minor bleeding, death rate had no statistical difference. (2)Knowledge lecture group (10.8±1.0 min) spend more time than the booklet group (1.0±0.5 min) (P<0.01). The booklet group (5.1±1.1 yuan) costed more in terms of money than the knowledge lecture group (1.8±0.5 yuan) (P<0.01). (3)The knowledge lecture group showed higher standard anticoagulation fulfillment rate (47.96%) than that of booklet group (32.60%) (χ2=7.33, P<0.01). There was no statistical difference in ischemic stroke rate, other artery embolism rate, major bleeding rate, minor bleeding rate and the death rate. Conclusions Detailed, correct anticoagulant education and guidance can improve NVAF patients with standard anticoagulation, and reduce the risk of ischemic stroke. Knowledge lecture consumes more time but can improve the standard anticoagulation fulfillment rate.

Objective To genotype the clinically isolated strains of M.leprae by genome sequencing analysis. Methods PCR amplification was used to produce the 200 bp partial rpoT gene fragments from 2 standard strains and the isolated strains of M. leprae isolated from clinical specimens in 7 areas of China. The fragments were sequenced by BigDye Terminator Cycle Sequencing Reaction kit. Results① 12 rpoT－ 91/97bp DNA fragments and 2 rpoT－ 194/200 bp DNA fragments were obtained from 13 clinically isolated strains of M. leprae by PCR amplification;② based upon genome sequencing analysis, a component of 3－ copy or 4－ copy“ GACATC” repeat sequence was found in the nucleotide sequence of rpoT－ 194/200 bp DNA fragment. Conclusion The genome sequencing analysis can be used to objectively and accurately genotype M.leprae, and it is a useful tool for epidemiological study on transmission and infection of leprosy. However, the longer DNA fragments are necessary when sequencing analysis is conducted. Therefore this method needs further improvement because only the shorter DNA fragments amplified from paraffin－ embedded tissue.

Objective To evaluate the methylation status of RASSF2A in epithelial ovarian cancer (EOC) tissues and plasma, and to explore the correlations in two kinds of samples with clinicopathological characteristics. Methods The frequency of methylation of the RASSF2A gene in tissues and corresponding plasma samples from 60 EOC patients, 20 patients with benign ovarian tumors and 10 patients with normal ovarian tissues were detected respectively. The methylation-specific PCR was used to determine the methylation status. Results The frequency of aberrant methylation of RASSF2A was 58.3% (35/60) in EOC tissues and 43.3%(26/60) in corresponding plasma samples respectively, however, such hypermethylation was not detected in the benign ovarian tumors and normal ovarian samples, and there was significant difference between them (P<0.05). Besides, RASSF2A methylation levels in serum of EOC patients correlated reasonably well with methylation status in tumor samples (r=0.739, P=0.000). No significant differences were observed between the promoter hypermethylated status of the RASSF2A and clinicopathological characteristics (P>0.05). Conclusions The promoter methylation of RASSF2A gene is an early and frequent epigenetic event in EOC. Detection of promoter hypermethylation in plasma specimens can help the early diagnosis of EOC.
