AIM: To investigate the molecular mechanism of Epstein-Barr virus encoded latent membrane protein 1 regulated cellular proliferation in nasopharyngeal epithelial cells. METHODS: The nasopharyngeal epithelial cells NP69 were infected with RV-pLNSX (the empty vector) and RV-LMP1 retroviruses, respectively. Therefore, the NP69-pLNSX and NP69-LMP1 cell lines were established. Sequentially, cellular proliferation of NP69-pLNSX and NP69-LMP1 cells was compared to draw the cellular growth curve. The experiments of plate clone formation and forming of soft agar colony were conducted. Meanwhile, the differential expression of proteins were identified between NP69-pLNSX and NP69-LMP1 cell lines by proteomic methods, and the expression levels of partial identified proteins were verified. RESULTS: (1) LMP1 was able to accelerate cellular proliferation of nasopharyngeal epithelial cell NP69 (n=3, P<0.05). (2) Twenty two proteins (9 up-and 13 down-regulated) of LMP1 mediated regulation were identified from infected NP69 cell lines, and the differential expression of partial identified proteins was confirmed by Western blotting and fluorescent real-time quantitative RT-PCR. CONCLUSION: LMP1 probably mediates the regulation of vimentin protein and keratin 19 protein expression to promote cellular proliferation in NP69 cells.

Background Congenital cataract is a major cause for blindness of childhood.Genetic gene mutation accounts for almost 1/3 of congenital cataract patients.The most common inheritance type is autosomal dominant congenital cataract (ADCC).Over 100 mutations in 26 genes have been found to be associated with ADCC.Objective This study was to identify the disease-causing gene mutation in a family with ADCC.Methods This study was approved by Ethic Committee of Beijing Tongren Hospital and followed Declaration of Helsinki.A northern Chinese family with autosomal dominant congenital nuclear cataract was entrolled in Beijing Tongren Hospital in January 2011.Ocular examinations were performed and periphery blood specimens were collected from each family member under the informed consent.Genomic DNA was extracted.Twenty-one microsatellite markers around 17 ADCC genes were selected for linkage analysis,and two-point LOD score was calculated.CRYGC gene and CRYGD gene were amplified and screened for mutations using direct sequencing.ProtScale software was used to analyze the changes of hydrophobicity of the mutated protein.Co-segregation of the observed change with the disease phenotype was further detected by restriction fragment length polymorphism (RFLP).Results This family included 20 members of 4 generations,and 9 patients were examined in serial 4 passages,which conformed to autosomal dominant inheritance pattern.Clinical examination revealed binocular congenital nuclear cataract in the 9 patients.Maximum two-point LOD score was 4.68 at marker D2S325 (θ=0).A known T→C change at position 127 of cDNA sequence was found by mutations screening of CRYGD gene.ProtScale programs showed an obvious increase of the local hydrophobicity in the mutant protein.RFLP results indicated that this missense mutation co-segregated with affected members of the family,but was absent in unaffected members and 100 unrelated controls.Conclusions c.T127C mutation of CRYGD gene appears to be the molecular pathogenesis of this ADCC family.Aberrant structure of mutant CRYGD protein caused by hydrophobicity change may lead to opacification of lens.

This paper was aimed to analyze the theoretical connotation with liver bodyyin with function yang, and to explain the physiological and pathological mechanism of body yin and function yang, respectively. The mechanism of its corresponding syndrome and symptoms were described and the composing principle of classical prescription for liver regulation was analyzed. The clinical significance of liver body yin with function yangwas confirmed by clinical cases. This paper argued that the liver ascending characteristics, which is a necessary guarantee for ascendingqi in the human body to adapt to the ascending gas of the world, is the key point to maintain balance of qi ascending and descending in the body. The liver ascending disorder mainly manifested for the excessive ascending and ascending deficiency, which analyzed the pathogenesis characteristic and clinical manifestation of the liver qi ascending disorder. This paper put forward a new view that the liver storing blood referred to the convergence and the conservation properties of the liver, which demonstrated the relationship between liver storing blood and controlling dispersion. It suggested that liver blood convergences liverqi so as not to make liverqi too excessive. The liver storing blood can raise spirit. Liver blood is the source of menstruation, and etc. This paper finally put forward the clinical prescription viewpoint of soothing liver and dropping inverse should raiseyin and gentle liver necessarily, releasing liver should raise liver and nourish blood and clearing away the liver-fire should cool blood and nourishyin. This research had certain clinical value.

Objective To explore the roles of p53 in ionizing radiation induced MCF-7 cell cycle uncoupling. Methods The p53 knock-down models was established in MCF-7 with retrovirus packaged particles from 293T cells through calcium acid phosphate co-precipitation, then Western blot was used to detect the protein expression. Flow cytometry(FCM) was used to analyze the cell cycle uncoupling and polyploid after irradiation. Results Compared with p53+/+ group, the percentages of G0/G1 cells in p53 -/- group decreased, while those of S and G2+M increased (P < 0.01). In polyploidy analysis 2N cells decreased, whereas both 4N and 8N cells =increased (P<0.01). Compared with sham-irradiation, 4 Gy X-ray led to the decrease of G0/G1, S cells, and the increase of G2+M cells. The increase of 2N cells and decrease of 4N and 8N cells were observed in both p53+/+ and p53-/- cells. Compared with p53+/+ +IR group, the decrease of G0/G1 and S cells and the increase of C2 + M cells were significant (P < 0.01) in p53-/-+ IR groups. 2N cells decreased, 4N cells increased, but no changes in 8 N cells occurred. Conclusion Radiation might induce G2 arrest and cycle uncoupling, p53 plays a role in the regulation of G2 arrest, but no role in cycle uncoupling.
