1.Preventive effect of statins for hepatocellular carcinoma
Cancer Research and Clinic 2016;28(7):501-504
Statins, hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors , are widely used as a class of lipid-lowering drugs in clinic. Recent studies have shown that the use of statins can be anti-inflammatory, anti-fibrosis and reduce the incidence of hepatocellular carcinoma (HCC), which may provide a new method for the preventive treatment of HCC. This article will review the current research progress of statins, including the clinical evidence, the molecular mechanisms of anti-inflammatory, anti-fibrosis and anti-tumor in liver.

Objective To investigate the association of the SNP in miRNA146A with genetic prediposion and earlier recurrence after resection for hepatocellular carcinoma (HCC).Methods In the casecontrol study including 173 HCC cases,DNA were exacted from cancer tissue embedded with paraffin and were amplificated by PCR,SNP was explored in gene sequence of miRNA146a (385 base pair including extron).The outcome were analyzed with genetic prediposion and clinical features.Result Only hsa-mir-146a rs2910164 was found.The genetype frequence of C/C 、G/G and C/G at rs2910164 gene locus were separately 61 (35.3%),21 (15%) and 86(49.7%) in cases.Compared to G/G genetype,C/C and C/G genetype were danger factor to onset risk of HCC (OR =3.086,95% CI:1.289-7.390) ; C/G was danger factor to earlier recurrence after resection(OR =8.179,95% CI:2.248-29.759).Conclusion rs2910164 may be associated with genetic prediposion and earlier recurrence after resection of HCC in Jiangxi hans
3.Progress of histone deacetylase in hepatocellular carcinoma
International Journal of Surgery 2008;35(9):609-612
Histone acetylation and deacetylation is an important regulatory way of gene expression in eukaryotic cells. As a key regulatory enzyme, histone deacetylase is overexpressed in many malignant tumors, including hepa- tocellular carcinoma. In addition, it has been suggested to be a potential therapeutic target for solid tumors. In this study, we review the classification, mechanisms, as well as the expression and regulation of histone deactylases in hepatocelhlar carcinoma.
4.Correlation between Ultrasonography and Pathology in Expansive Type of Hepatocellular Carcinoma
Chinese Journal of Ultrasonography 1995;4(6):247-250
Expansive type of hepatocellular carcinoma (HCC) is a subtype of HCC. Correlation between the preoperative sonography and postoperative pathology was studied in 35 cases of HCC. According to the classification of nakashima, 21 cases belonged to the expansive type whereas the other 14 cases the infiltrative type. Different from the infiltrative type. the expansive type of HCC had four specific sonographic appearances: hypoechoic ring, hypoechcic halo, pedunculated and small nodular echo which had different pathological bases. Expansive tyje of HCC was not so commonly seen as infiltative type but its rate of surgical resection was mu~h higher than that of infiltratine type (JP< 0. 01). Thus, it is the kind of HCC with significant clinical importance. Preoperative ultrasonographic diagnosis help to decide the way of treatment.
5.Expression of Inducible Nitric Oxide Synthase and NF-κ Bp65 in Patients with Psoriasis Vulgaris and Their Clinical Significance
Chinese Journal of Dermatology 2001;34(2):103-104
Objective To investigate the internal relationship between the expression of inducible nitric oxide synthase (iNOS) and the activation of NF-κ Bp65 in the skin of patients with psoriasis vulgaris(PV) and their roles in the pathogenesis of PV.Methods The expression and distribution of iNOS and NF-κ Bp65 were studied by in situ hybridization and immunohistochemistry in 20 patients with PV and 12 healthy controls.The severity of PV was assessed by Psoriasis and Severity Index(PASI) score.Results ① The expression of both iNOS mRNA and protein was significantly higher in lesional epidermis than those in non-lesional epidermis and epidermis of the controls (P<0.01).Weak exprssion of iNOS mRNA was found in basal cell layer in a small number of healthy controls, however, strong expression was observed in entire basal cell layer and focal parts of prickle cell layer in all PV epidermis.② There was significantly positive correlation between iNOS and NF-κ Bp65 protein expression in lesional epidermis (P< 0.01).③ There was significantly positive correlation between the level of expression of iNOS mRNA in lesional epidermis and PASI score of patients (P< 0.01).Conclusions The expression of iNOS and NF-κ Bp65 is markedly increased in lesional epidermis of patient with PV.The activation of NF-κ B probably takes part in the pathogenesis of PV.High-level expression of iNOS may be due to the activation of NF-κ B.
