Functions of the 3′untranslated regions (3′UTR) of eukaryotic mRNAs are complicated. They can control the stability and intracellular localization of mRNAs, and direct the translation of special amino acids. Mutations in the 3′UTR of some mRNA can cause serious diseases, and recent studies showed that the 3′UTR of some eukaryotic mRNAs possess tumor-suppression function.

Objective To evaluate the clinical aesthetic effect of immediate implant and immediate prosthesis by the free connec-tive tissue transplantation with periosteum in the maxillary anterior region.Methods 65 appropriate patients were selected and per-formed the immediate implant after minimally invasive tooth extraction.6 5 pieces of implants were implanted immediately by the free connective tissue transplantation with periosteum in the aesthetic area,among them,10 cases were implanted by Bio-oss bone. All missing teeth were immediately repaired by temporary denture,after the implant osseointegration,the permanent repair was per-formed.From the preoperation to 1 8 months after permanent repair,the aesthetic evaluation was conducted by stages,including the labial peri-implant soft tissue fullness and pink aesthetic scores(PES).Results In the tracing assessment period,the peri-implant fullness evaluation showed that degree 0 was found in 5 tooth positions before the operation,degree Ⅰin 60 tooth positions,degreeⅡ in 0 tooth position,but after immediate restoration,degree 0 in 0 tooth position,degree Ⅰin 45 tooth positions and degree Ⅱ in 20 positions.The PES total value reached the maximum in 3 months after permanent restoration.Conclusion Immediate implant and immediate prosthesis by the free connective tissue transplantation with periosteum in the maxillary aesthetic area can obtain better aesthetic results.

Objective: To further investigate the molecular mechanism of photodynamic therapy. Methods: We used cDNA microarray technique to explore the gene expression profiles of HEPG2 cells after photodynamic therapy with hematoperphyrin monomethyl ether(HMME) in HEPG2 cells. After treated with HMME for 60 min, the HEPG2 cells were irradiated with laser, and observed by microscope with H E staining. To prepare the probes, mRNA from both control and treated cells were isolated and purified, then reversely transcribed to cDNA with the incorporation of fluorecent labeled dUTP. The probes were hybridized with a cDNA microarray representing the 1 538 genes originated from human hepatocarcinoma cells. The fluorencent signals of Cy3 and Cy5 were scanned and analyzed. Results: After laser irradiation, the HEPG2 cells showed the typical feature of apoptosis. The gene expression profiles were also changed greatly. Among the 1 538 target genes, 389(2.47%) different expression genes were detected. Most of the changed genes (nearly 80%) were down regulated. They were functionally related to cell proliferation cycle, replication, metabolism and so on. Several apoptosis associated genes were detected among those up regulated genes, encoding the key proteins involved in apoptosis signal transduction, such as CCP32,AIF,Mch2. Conclusion: The HMME photodynamic therapy can initiate the apoptosis process of HEPG2 cells, which may be regulated by mitochondial pathway.[
