With the development of dental implant techniques, dental rehabilitation of partially or totally edentulous patients with oral implants has become a common practice. Adequate bone volume in the implant area is a key factor for the success of implant restoration. However, insufficient bone volume in the implant area is very common in clinical practice, which jeopardizes the structural, functional, and esthetic outcomes of implant treatment. Bone augmentation with bone grafts is one of the methods commonly used in clinical practice to meet the requirements of implantation. Properties of bone grafts, such as biocompatibility,osteoconduction, osteoinduction and osteogenesis, are important to the success of bone augmentation. This paper reviews current research on dental bone grafts about their clinically relevant capabilities, classification and their potential development in the future, in order to provide theoretical reference for clinical application of bone grafts and successful implant restoration.

Objective To investigate the feasibility and safety of transvaginal endoscopic cholecystectomy.Methods The clinical data of 88 female patients who underwent cholecystectomy at the Qilu Hospital of Shandong University from May to November, 2009 were retrospectively analysed. Among all the patients, 32 received transvaginal endoscopic cholecystectomy ( NOTES group) and the remaining 56 patients received laparoscopic cholecystectomy (LC). Thirty-two patients who received LC at the same period were selected (LC group)acccording to age, body mass index, type and severity of disease to conduct a matched case-control study. The differences in time span of postoperative pain, anodyne dose, enterokinesia recovery time, operation time, out-ofbed activity time, average hospital stay and hospitalization expenses between the two groups were compared using the paired t test. Results Cholecystectomies were successfully carried out for all the patients. The intraoperative blood loss, operation time, degree of pain, anodyne doses, enterokinesia recovery time, out-of-bed activity time,average hospital stay and hospitalization expenses were (5.7 ± 1.5 ) ml, ( 76 ± 27 ) minutes, 2.2 ± 0.6, ( 10 ±6) mg, (25±5) hours, (9±3) hours, (2.1 ±1.2) days and (1.12±0.34) ×104 yuan in NOTES group, and they were ( 13.9 ± 3.1 ) ml, (38 ± 16) minutes, 6.7 ± 1.5, (28 ± 8) mg, (45 ± 8) hours, (26 ± 6) hours,(4.3 ± 2.1 ) days and ( 1.54 ± 0.18 ) × 104 yuan in the LC group. There were significant differences between the two groups (t = 5.098, - 4.712, 2.417, 3.203, 3.089, 4.136, 4.786, 3.917, P ＜ 0.05 ). Conclusion Transvaginal endoscopic cholecystectomy is safe and feasible, and it is superior to tranditional LC.

BACKGROUND:5-Fluorouracil occupies an important position in the treatment of gastric cancer, but its long-term use can easily induce adverse reactions such as myelosuppression and leukopenia. Polylactic acid and its copolymers have a higher biocompatibility, and their decomposer cannot gather in the body.
OBJECTIVE:To investigate the in vitro cytotoxicity mechanism of 5-fluorouracil-loaded polylactic acid nanoparticles on gastric cancer cel lines.
METHODS:Ten mice were selected in this study. 5-fluorouracil-loaded polylactic acid nanoparticles (1×10-7, 1×10-6, 1×10-5, 1×10-4 mol/L) were prepared using ultrasonic emulsification method. Kiling effect of polylactic acid nanoparticles on gastric cancer cel lines in vitrowere detected. Then, the inhibition rate was calculated at different concentrations.
RESULTS AND CONCLUSIONS: Under the transmission electron microscope, 5-fluorouracil-loaded polylactic acid nanoparticles had good shape and relatively evenly distributed with no adhesions. After drug administration, the drug concentration was 50% at 24 hours and 62.9% at 72 hours. After 48 hours co-culture with single 5-fluorouracil or 5-fluorouracil-loaded polylactic acid nanoparticles, the viability of gastric cancer cels showed a decrease trend with the increase of drug concentrations, and moreover, 5-fluorouracil-loaded polylactic acid nanoparticles had a better cel inhibition ability than the single 5-fluorouracil (P < 0.05). The IC50value of 5-fluorouracil-loaded polylactic acid nanoparticles was significantly lower than that of 5-fluorouracil (P < 0.05). These findings indicate that polylactic acid nanoparticles as good drug carriers have a strong drug loading capacity and increase drug concentration in the body, but cannot reduce the biological activity of 5-fluorouracil, which provide new ideas for the treatment of gastric cancer.
