BACKGROUND:Chitosan hydrogel has good biocompatibility, biodegradability and antibacterial property, which can promote tissue healing and induce bone formation. As a scaffold carrying growth factors, it can ensure the efficient and slow release of exogenous growth factors.
OBJECTIVE: To observe the effect of injectable nano/chitosan/bone morphogenetic protein-2 composite to promote periodontal tissue regeneration in rats.
METHODS:Fifty-four Wistar rats were randomized into three groups, and then chronic periodontitis model of the second molar was established. After modeling, injectable nano/chitosan/bone morphogenetic protein-2 composite was implanted into the periodontal tissue of the second molar in the experimental group; injectable nano/chitosan hydrogel was implanted in the control grouop; and nothing was implanted in the blank group. At 3, 6, 9 weeks after surgery, gingival bleeding index, probing depth, and tooth mobility were detected. X-ray and histopathological observations were carried out.
RESULTS AND CONCLUSION:At 9 weeks after surgery, the probing depth and tooth mobility were both lower in the experimental group than the other two groups (P < 0.05). In the experimental group, the alveolar bone height was restored at the root bifurcations, bone trabeculae were arranged densely and evenly, the newly formed periodontal ligament and alveolar bone tissues were dense and equaly distributed in the bone defect area at 9 weeks after surgery, indicating a better restoration effect than the control and blank groups. These findings suggest that the injectable nano/chitosan/bone morphogenetic protein-2 composite has an anti-inflammatory role and can guide periodontal tissue regeneration.

[Abstract ] Objective To evaluate the inhibitory effect of chlorogenic acid on senescence of human skin fibroblasts (HSFs). Methods Fibroblasts isolated from human foreskin were treated with 1 mmol/L glyoxal in vitro to develop a model for cellular senescence. In order to select effective concentrations of chlorogenic acid, some HSFs were treated with 1 mmol/L glyoxal alone or in combination with chlorogenic acid at different concentrations (5, 10, 20, 40, 80 μmol/L)for 3 days, with those receiving no treatment serving as the blank control group. Then, methyl thiazolyl tetrazolium (MTT)assay was performed to evaluate the proliferative activity of HSFs. Some HSFs were divided into 5 groups to be cultured alone(blank control group), or treated with 1 mmol/L glyoxal(glyoxal group)or the combination of 1 mmol/L glyoxal and chlorogenic acid at effective concentrations of 10, 20 and 40 μmol/L (glyoxal + chlorogenic acid groups). Senescence associated β-galactosidase (SA-β-gal)staining and real-time fluorescence-based quantitative PCR were conducted to determine the percentage of senescent cells and expression level of p16INK4a mRNA respectively. Statistical analysis was carried out by one-way analysis of variance followed by the least significant difference(LSD)-t test. Results Compared with the blank control group, the glyoxal group showed significantly decreased cellular proliferative activity of HSFs (55.65% ± 2.00% vs. 100% ± 6.90%, P < 0.01), while chlorogenic acid increased the proliferative activity of HSFs in a dose-dependent manner, and the increase reached a peak at 40 μmol/L. Concretely speaking, the glyoxal + 10-, 20-, 40-, 80-μmol/L chlorogenic acid groups all significantly differed from the glyoxal group in cellular proliferative activity (60.75% ± 1.32%, 67.65% ± 1.90%, 75.71% ± 3.25% and 75.69% ± 2.38% vs. 55.65%± 2.00%, all P < 0.05), but no significant difference was observed between the glyoxal group and glyoxal + 5-μmol/L chlorogenic acid group or between the glyoxal + 40-μmol/L chlorogenic acid group and glyoxal + 80-μmol/L chlorogenic acid group (both P > 0.05). Therefore, 10 - 40 μmol/L was selected as the effective concentrations of chlorogenic acid. The glyoxal group showed significant increases in the percentage of senescent (SA-β-gal-positive)cells (35.65% ± 2.24% vs. 13.00% ± 2.22%, P < 0.01)and expression level of p16INK4a mRNA (2-ΔΔCt: 1.00 ± 0.06 vs. 0.26 ± 0.05, P <0.01)compared with the blank control group, while the glyoxal + 10-, 20-, 40-μmol/L chlorogenic acid groups showed significantly decreased percentage of senescent cells (31.50% ± 2.13% , 22.31% ± 3.11% and 19.32% ± 3.01%respectively)and expression level of p16INK4a mRNA (2-ΔΔCt: 0.88 ± 0.08, 0.73 ± 0.06 and 0.68 ± 0.04 respectively) compared with the glyoxal group (all P < 0.05). Additionally, the percentage of senescent cells decreased with the increase in chlorogenic acid concentrations in the glyoxal + chlorogenic acid groups. Conclusion Chlorogenic acid can protect HSFs from glyoxal-induced senescence.

Objective To discuss the clinical value of application of three-dimensional reconstruction technique of MSCT in examination of colonic tumours.Methods Thirty patients underwent scanning using helical CT and post-processing on the workstation.All CTC images were reconstructed using shaded surface display (SSD) on workstation.Perspestive images such as the ones from DCBE were generated via raysum.The images could clearly demonstrate the extent and detail of the disorder by adjusting the CT value threshold.These results and that of barium enema and colon endoscopy were compared.Results Thirty cases had completely clinical and pathological data.3D images could correctly reveal the macroscopic morphology of colon tract and location of lesions.The correctly diagnostic rate was 100％ by MSCT,while the diagnostic rate by CTVE and colon endoscopy was basicly identical.Conclusion With the utilization of multiple methods,3D reconstruction can effectively demonstrate colonic tumours,and can be applied routinely in examination of colonic tumours.
