RESUMO
@#The in itiation and progression of periodontal disease were reported to be the results of complicated interactions between specific subgingival bacteria and host immuno-inflammatory response. As a part of the immune and defense system mechanisms of the host, leptin may have a protective effect on periodontal tissues. We summarize the latest progress in the relationship between leptin and periodontitis.
RESUMO
Background Optimization of nutrient feeding was developed to improve the growth of Bacillus subtilis in fed batch fermentation to increase the production of jiean-peptide (JAA). A central composite design (CCD) was used to obtain a model describing the relationship between glucose, total nitrogen, and the maximum cell dry weight in the culture broth with fed batch fermentation in a 5 L fermentor. Results The results were analyzed using response surface methodology (RSM), and the optimized values of glucose and total nitrogen concentration were 30.70 g/L and 1.68 g/L in the culture, respectively. The highest cell dry weight was improved to 77.50 g/L in fed batch fermentation, which is 280% higher than the batch fermentation concentration (20.37 g/L). This led to a 44% increase of JAA production in fed batch fermentation as compared to the production of batch fermentation. Conclusion The results of this work improve the present production of JAA and may be adopted for other objective products' production.

<p><b>OBJECTIVE</b>To observe the microstructural changes of olfactory mucosa in rat model with acute rhinosinusitis leading to olfactory dysfunction, and to provide foundation for further exploration of corresponding mechanism.</p><p><b>METHODS</b>On the basis of prior successfully established rat model of acute rhinosinusitis through inoculation with Streptococcus pneumoniae and with the help of merocel strips, one hundred healthy SD rats were randomly divided into experimental group (80) and control group (20). After inoculation, every 20 rats in the experimental groups were sacrificed in first week, second week, third week and fourth week respectively; and all rats in the control group were sacrificed in first week after the inoculation. Before the rats were sacrificed, the method called "buffed food pellet test, BFPT" was adopted, which was advanced by professor Nathan, to measure the rats' olfaction,and the time of every rat spending in finding out the food pellet was recorded and analyzed. BFPT showed that the rats in experimental group spent (402.9 ± 9.3), (453.7 ± 7.3), (351.9 ± 8.9), (278.7 ± 8.1) s respectively in searching the food pellet, which were more than the rats in the control group [(178.3 ± 6.6) s]. Then the olfactory mucosa was collected under anatomic microscope from all the rats to make frozen section and detect the changes of mature olfactory receptor neurons (ORN) and olfactory ensheathing cells (OEC) by immunofluorescence technique.</p><p><b>RESULTS</b>The reduction of ORN in various degrees could be detected in the tissue samples of olfactory mucosa among all the rats in experimental group, with a tendency to become thinner in the thickness of epithelial lamina during the inflammation developing course. This kind of pathology was most marked in the second week and it gradually developed into the stage showing the lesion being the feeblest in the forth week following the beginning of modeling. Although the number of olfactory ensheathing cells appeared reduction in the first week following the beginning of modeling as well,it came to increase from the second week before olfactory receptor neurons and almost completely recovered to normal in the fourth week. In addition, some olfactory ensheathing cells could be detected in the tissue samples of olfactory mucosa among all the rats in experimental group.</p><p><b>CONCLUSIONS</b>Both mature olfactory sensory neurons and olfactory ensheathing cells appeared to reduction when sinonasal mucosa taken place acute rhinosinusitis. But the number of olfactory ensheathing cells increased faster than olfactory sensory neurons. In addition, some olfactory ensheathing cells could be detected in the olfactory epithelium.</p>

Response surface methodology (RSM) was used for statistical optimization of jiean-peptide (JAA) production by Bacillus subtilis ZK8 cells adsorbed on wood chips to form a novel fermentation system. The Plackett-Burman design was used in the first step to evaluate the effects of eight factors, including six fermentation medium components and two cell adsorption conditions. Among the variables screened, soybean meal hydrolysate (SMH) and MgSO4A7H2O in the fermentation medium had significant effects on JAA production. In the second step, the concentrations of SMH and MgSO4A7H2O were further optimized using central composite designs and response surface analysis. The optimized concentration of SMH and MgSO4À7H2O was 24 percent (v/v) and 0.38 percent (w/v), respectively, which increased the production of JAA in a shake flask system by 41 percent relative to optimization of a single variable component of the culture medium.

<p><b>OBJECTIVE</b>to explore the value of in vivo dynamic monitoring of abdominal aortic atherosclerosis (AS) by high field magnetic resonance (MR) imaging (MRI) in apoE-/- mice fed a high fat diet or infused with angiotensin.</p><p><b>METHODS</b>high fat diet or angiotensin II infusion was applied to apoE-/- mice for establishment of abdominal aortic atherosclerosis model. Abdominal aorta MRI was performed at 3 time points (baseline, 3 and 6 months) in 13 high fat diet fed apoE-/- mice aged 10-12 months and 3 wild-type control mice; 10 apoE-/- mice aged 6 months were infused with angiotensin II (1000 or 500 ng × kg(-1)× min(-1), n = 5 each) or saline for 14 d through Osmotic minipump. The abdominal aortic artery MRI was performed at baseline and 14 d after infusion. Black blood sequences of FLASH T1 weighted images and Proton density weighted-T2 weighted dual echo images were obtained. At each observation time post MRI, mice (n = 3, 5 and 5 for high fat diet group and n = 5 and 5 for angiotensin II infusion group) were sacrificed for pathological examination of the abdominal artery.</p><p><b>RESULTS</b>(1) the abdominal aorta atherosclerosis was identified in both high fat diet and angiotensin II treated apoE-/- mice but in WT controls. Lesion progression was documented in high fat diet fed apoE-/- mice characterized by significantly increased vessel wall (a marker of atherosclerotic burden, F = 29.94, P < 0.05) and gradually increased plaque signal in PDW and T2W images. Results derived from MRI corresponded histopathology findings in high fat diet fed apoE-/- mice (correlative coefficient = 0.84, 0.95, 0.90, P < 0.05, respectively). Both MRI and histology showed increased lipid composition and decreased fibrotic composition in these mice. (2) The vessel wall area increased significantly [(1.21 ± 0.21) mm(2) vs. (2.65 ± 0.48) mm(2), P < 0.05] and the abdominal aortic dissection aneurysms was identified in apoE-/- mice infused with high angiotensin II. The vessel wall area also increased [(0.85 ± 0.11) mm(2) vs. (1.01 ± 0.17) mm(2), P < 0.05] in low angiotensin II infused apoE-/- mice and the coefficient between MR and histopathology is 0.934.</p><p><b>CONCLUSION</b>abdominal aortic unstable plaque model could be established by both high fat diet and angiotensin II infusion in apoE mice, angiotensin II infusion can transiently accelerate the progression of AS and can induce abdominal aortic dissection. Serial MR black blood sequences could demonstrate the development and progression of atherosclerosis in mouse abdominal aorta with excellent agreement to histopathology finding in terms of atherosclerotic burden and plaque composition. Thus, MRI appears to be a useful tool for in vivo AS plaque dynamic monitoring in mice.</p>

<p><b>UNLABELLED</b>OBJECTIVE To study the effects of TiO2 blasted and acid-etched surfaces of cp-titanium on changing composition of oxide-film and attachment and proliferation of osteoblasts in vitro.</p><p><b>METHODS</b>cp-titanium discs were prepared and divided into 4 groups: TiO2 blasted (SB), sandBlasted and acid-etching (SLA1 and SLA2) and machine-polished surface (S1). Scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron probe microanalysis (EPMA) were used to test surface morphology and composition of oxide-film. Osteoblasts were cultured on the titanium surface of 4 groups. MTT assay was used to measure the attachment and proliferation.</p><p><b>RESULTS</b>In regard to surface roughness, average roughness for SB, SLA1 and SLA2 was obviously higher than S0 Oxygen ratio increased on SB,contrarily, it decreased on SLA. A mixture of anatase and rutile-type crystals were observed in the SB. Smaller anatase were observed in the SLA1 and SLA2. The oxide thickness on SLA surface was thiner than that on the SB surface. Alter 1, 4, 24 hours' culture, the number of osteoblast attachment on SB surfaces was the highest (P < 0.05). The number of cells osteoblast proliferation was the highest on SB after 1, 3, 5 and 7 days' culture (P < 0.05).</p><p><b>CONCLUSION</b>The thickness and chemical composition of oxide film play an important role in osteoblast attachment and proliferation at the same roughness surface. It is concluded that osteobla.st attachment and proliferation are better on SB surfaces than on SLA1 and SLA2 surfaces.</p>

<p><b>UNLABELLED</b>OBJECTIVE To evaluate the effects of grooved, alkali- and heat-treated, acid-etched and TiO2 blasted surfaces of titanium substrates on F-actin cytoskeleton of osteoblasts in vitro.</p><p><b>METHODS</b>Osteoblasts derived from fetal rat calvarial were cultured on 6 different commercially pure titanium discs-grooved(G), sandblasted (SB), sand-blasted and acid-etching (SLA) surfaces and alkali- and heat-treated (AH1, AH2, AH3) surfaces. For F-actin cytoskeleton measurement, osteoblasts whose filamentous actin was stained with phalloidin-TRITC were cultured for 1, 2, 4, 12 h, evaluated by CLSM observation.</p><p><b>RESULTS</b>Osteoblasts attached to the different types of surfaces after 1 hour culture were similar. The actin cytoskeleton formed a ring of cortical filaments around the nucleus after 1 hour on SB, AH2, AH3, SLA surfaces. Actin filaments condensed along edges of pits. The actin filaments of seeded cells were spread after 2 h. The actin filaments on G formed bundles around the nucleus. The filaments began to parallel to the grooves. On AH1, the fibres formed a ring of cortical filaments around the nucleus with some cytoplasmic fibres radially oriented. On AH2, AH3, SB, the fibres orignised in a cytoplasmic meshwork with fibres which terminate at the ridge of depressions. The cell were suspending itself over the depressed areas. Actin filaments on SB were distinct and well formed that were oriented paralled to one another and the long axis of cells. After 4 h, actin filaments appeared organised in a parallel to one another and the long axis of cells. After 12 h, the actin filaments on all surfaces were well spread and were oriented paralled to another and to the long axis of the cell. The filaments formed bundles which reached to holes or adhered to the ridge of raised points, suspending cells over depressed areas.</p><p><b>CONCLUSION</b>After 12 h, the actin filaments on all surfaces were well spread and were oriented parallel to another and to the long axis of the cell. It was concluded that F-actin cytoskeleton of osteoblasts were spread best on SB surfaces among all surfaces.</p>

<p><b>OBJECTIVE</b>To explore the role of eotaxin in the pathogenesis of bronchial asthma and the clinical value in the diagnosis of asthma.</p><p><b>METHODS</b>Serum eotaxin were measured by ELISA in 38 patients with asthma, 28 patients with non-asthma allergy, and 30 healthy controls.</p><p><b>RESULTS</b>The levels of serum eotaxin in the asthma group were higher than those in the non-asthma allergic and control group (P<0.01). Furthermore, eotaxin levels in patients with acute asthma were significantly higher than those in patients with stable asthma (P<0.001). It was also found that the eotaxin levels of the acute asthma group were positively correlated to the amounts of eosinophils in peripheral blood (r=0.4196, P<0.001), and inversely correlated to the forced expiratory volume in one second (FEV1) (r=-0.3746, P<0.001).</p><p><b>CONCLUSION</b>It suggests that eotaxin may play a crucial pathogenic role in the asthmatic process possibly by activating the allergic inflammatory cells and controlling the recruitment of eosinophils from blood to bronchial epithelium of the airway. The concentration of eotaxin is significantly associated with the attack of acute asthma and its severity. Eotaxin may be a potential therapeutic target in patients with asthma.</p>
