Periodontitis is a chronic infective disease characterized as the destruction of the supporting tissues of the teeth. Bone marrow mesenchymal stem cells, which are ideal adult stem cells for the regeneration of supporting tissues, may play important roles in restoring the structure and function of the periodontium and in promoting the treatment of periodontal disease. As a consequence, the characteristics, especially osteogenic differentiation mechanism, of these stem cells have been extensively investigated. The regulation of the physiological behavior of these stem cells is associated with BMAL1 gene. This gene is a potential treatment target for periodontal disease, although the specific mechanism remains inconclusive. This study aimed to describe the characteristics of BMAL1 gene and its ability to regulate the osteogenic differentiation of stem cells.

Objective: To explore the efficacy of mild moxibustion plus loratadine tablets for children with allergic rhinitis (AR).Methods: A total of 80 children were randomized into a control group and an observation group, with 40 cases in each group. The control group was treated with loratadine tablets, and the observation group was treated with mild moxibustion plus loratadine tablets. Before and after treatment, the total nasal symptom score (TNSS) was evaluated, and the serum eosinophils (EOS) count, and the interleukin (IL)-27 and macrophage migration inhibitory factor (MIF) levels were measured. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, the TNSS in both groups decreased (P<0.05), and the TNSS in the observation group was lower than that in the control group (P<0.05); the serum EOS count in both groups decreased (P<0.05), and the serum EOS count in the observation group was lower than that in the control group (P<0.05). The serum IL-27 level in the control group had no statistical difference compared with the same group before treatment (P>0.05), and the serum MIF level decreased after treatment (P<0.05). The serum IL-27 level in the observation group increased after treatment (P<0.05), and the serum MIF level decreased after treatment (P<0.05), and were both statistically different from those in the control group (P<0.05). Conclusion: Mild moxibustion plus loratadine tablets is effective in treating children with AR. It can significantly improve the nasal symptoms and reduce the serum EOS count, which may be related to the regulation of the serum IL-27 and MIF levels.

0.05).Conclusion:So-fastTM can greatly improve the penetration of PS-ODN into S.mutans and can be used as appropriate delivery system of PS-ODN for S.mutans. No matter what approaches were adopted, the uptake rate reached the maximum at 5 ?mol/L and 2 h-exposure. The penetration can not be enhanced by increasing the PS-ODN concentration and the transformation time.

Her-2 receptor has already been identified as one of the most important biological markers of some malignant tumors,and also plays an important role in the biological behavior of those tumor cells.The over-expression of Her-2 receptor is associated with radioresistance of various tumor cells,and thus an antibody to Her-2/neu receptor can probably function as a radiosensitizer.In this review,we summarized some advances in the molecular mechanism and clinical aspects of the relationship between Her-2 and cellular radiosensitivity.

Objective To explore the change of serum level of neuron specific enolase (NSE) in neonates with asphyxia before and after head mild hypothermia.Methods Eighty-two asphyxial neonates were selected,including 39 mild asphyxial neonates and 43 severe asphy-xial neonates,and 29 healthy neonates were selected as control group.Forty-three severe asphyxial neonates were randomly assigned into mild hypothermia treatment group and traditional treatment group.Neonates in traditional treatment group were just given traditional treatment.While neonates in mild hypothermia treatment group received head mild hypothermia therapy and their nasopharyngeal temperature were maintained at(34.0 ? 0.5) ℃ for 72 h.Before treatment and 72 h after treatment,2 mL blood was collected,and the serum NSE was determined by radio immunoassay.Results NSE levels in mild asphyxial neonates group[(34.83?6.17) ?g/L] and severe asphyxial group[(59.58?8.87) ?g/L] were significantly higher than that of control group[(30.57?4.88) ?g/L](t=3.07 P0.05).The level of NSE at 72 h in severe asphyxial neonates with head mild hypothermia therapy[(40.97?6.55) ?g/L] was significantly lower than that of traditional treatment group [(48.15?5.57) ?g/L](t=3.86 P

Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.
