0.05),respectively.Conclusion:LED curing light can reach the performance level of halogen curing light and is suitable for routine oral clinical application for resin curing.

Objective:To investigate the influence of type A behavior in the occurrence and development of chromic periodontitis and compare the differences among people with different behavior types in the occurrence and development of chronic periodontitis, and to explore the influence of psychological factors in the process of periodontitis.Methods:According the same standard,132 patients with periodontitis were selected as periodontitis group,and 126 patients without periodontitis were used as control group.OralSurveys Basic Methods proposed by WHO in 1987 and ReferenceStandard of Diagnosis and Treatment of Periodontitis made by AAP in 2000 were used to dignose the periodontitis.All subjects finished type A behavior and SCL-90 questionnaire (ZHANG Boyuan 1983,revision in 1985 ), their scores were recorded and the results were analyzed by t test. Results:The proportion of type A behavior in periodontits group (68.94%)was higher than that in control group (27.78%) (P<0.05)compared with type M and type B behavior.The scores of hostility (1.54±0.38),anxiety (1.47± 0.39),depression (1.41 ± 0.37),interpersonal sensitivity (1.23 ± 0.39),compulsive (1.72 ± 0.46),and somatizition (1.47 ± 0.38)were significantly higher than those in control group (1.32 ± 0.30, 1.29 ± 0.24, 1.25±0.23,1.04± 0.17,1.41 ± 0.35,1.25 ± 0.24).The calculus index (CI)of the people with type A behavior was higher than those of the people with other types of behavior (P<0.05).Conclusion:The people with tyep A behawior is easier to get periodontitis than other people.

Objective To express the anti-IL-1βscfv and soluble TNF receptor 1 (sTNFR1),and analyze their bio-activities.Methods sTNFR1 was obtained by RT-PCR from the total RNA of HeLa cells,and fused with IL-1βscfv by the hinge fragment of IgG molecule.The fusion gene IL-1scfv:TNFR1 was cloned into the expression vector pET27b(+).The fusion protein was expressed and purified from inclusion bodies.Results The ELISA analysis showed that the fusion protein could bind hIL-1β and hTNF-α respectively in a dose-dependent manner,indicating that scfv and sTNFR in the fusion protein can form the correct spatial configuration.The dolt-blot analysis showed that the fusion protein could concurrently bind with hIL-1β and hTNF-α,indicating that the combination of the two parts of the fusion protein does not influence each other for binding to their target molecules.The bioactivity assay showed that the fusion protein could inhibit both the cytotoxicity of hTNF-α on L929 cells and hIL-1β-induced proliferation of L929 cells,indicating that the fusion protein has the ability to neutralize hTNF-α and hIL-1β.Conclusion A bispecific fusion protein IL-1scfv:TNFR1 was successfully constructed.The fusion protein has the ability to inhibit the biological activity of hTNF-α and hIL-1β,and provides a drug candidate for the treatment of rheumatoid arthritis.

This paper summarized nursing experience of 23 patients with malignant tumor treated by 3D printing individualized template and 125I seed implantation.Nursing points included:preoperative assessment and preparation,reviewing the process of template conduction,assisting the physician to simulate the position of patients,making treatment plans,preparing templates before operation;resetting and maintaining position of patients,performing template alignment,seed implantation,monitoring vital signs and complications during operation;observation of complications,providing radiation protection and discharge guidance after operation.All 23 patients completed 125I seed implantation and no serious complication was observed.All patients recovered well and were discharged after treatment.

As the most important pathological feature of periodontitis, alveolar bone resorption also results in tooth loss and oral dysfunction. According to recent research, the host immune response is the major factor leading to alveolar bone resorption. Antibodies, immune cells and inflammatory cytokines involved in this procedure cause an imbalance of bone formation and destruction, which is called osteoimmunity. Given the importance of adaptive humoral immunity during periodontitis, B cells are considered crucial in the development of periodontitis. Therefore, establishing B cell osteoimmunity is an effective way for us to deeply assess the start, development and prognosis of periodontitis. It has been proven that the development process of B cells is accompanied by changes in bone density or morphology. We have reviewed previous literature to understand the role of B cell bone immunity in the pathological process of periodontitis, and the results showed that B cells regulate the development of bone cell lines through transcription factors (such as RANKL, PU.1, E2A, etc.). In addition, various cytokines expressed by B cells (such as IFN-γ, IL-17, IL-10, TGF-β, etc.) can participate in the regulation of bone cells.

OBJECTIVE: To analysis the causes and treatment for postnasal drip syndrome. METHOD: One hundred patients were tested by routine examination of otolaryngology, nasal endoscopy, fiberoptic laryngoscopy and nasal sinuses CT. Choice allergen test and nasopharynx X-ray were taken based on the symptoms and signs. Patients were treated accordingly for different causes, such as flushing the nasal cavity by herbal liquid, using glucocorticoid locally, taking medicine of improving the sticky film cilium function, immunotherapeutic or operation. RESULT: The causes included chronic rhinitis 22 cases (22%), chronic sinusitis or nasal polyp 31 cases (31%), allergic rhinitis 28 cases (28%), adenoid vegetation 16 cases (16%), chronic nasopharyngitis 3 cases (3%). All patients were treated accordingly and total cure rate was 82% after 6 months follow up. CONCLUSION The causes of postnasal drip syndrome are complicated. It is critical to check the cause and chose adaptable therapy for good result.

【Objective】 To analyze the expressions of IL-10, IL-35 and TGF-β in CD25⁺B cells from periodontitis individuals, and then establish how the activation of TLR4/9 affects the above processes. 【Methods】 SD rats were randomly divided into healthy group, primary periodontitis groups and severe periodontitis group; experimental models were performed by ligation. Expression of IL-10, IL-35 and TGF-β mRNA in CD25⁺B cells from gingiva and peripheral blood, expression and activation of TLR 2/4/7/9, MyD88, TRAF6 in gingival CD25⁺B cells were detected. The effect of TLRs/MyD88 on IL-10, IL-35 and TGF-β expressions and production were evaluated by cell culture experiments. 【Results】 CD25⁺B cells from gingiva of primary periodontitis individuals showed improved expression of IL-10 and TGF-β mRNA compared with the healthy ones (P<0.05); cells from peripheral blood did not present the same tendency. CD25⁺B cells from gingiva of severe periodontitis individuals showed improved expression of IL-10, IL-35 and TGF-β mRNA compared with the healthy ones (P<0.05), cells from peripheral blood showed higher IL-10 mRNA level than the healthy ones (P<0.05). Compared with healthy individuals, the expression and phosphorylation of TLR4/9 and MyD88 in CD25⁺B cells from gingiva of severe periodontitis individuals were increased (P<0.01). In cell culture experiments, TLR4 agonist promoted IL-10, IL-35 and TGF-β mRNA expression and IL-10 secretion (P<0.05); TLR9 agonist improved IL-10 and TGF-β mRNA expression and IL-10 secretion (P<0.05). The combined use of TLR4/9 agonist could increase the expression and secretion of all the detected indexes (P<0.05); MyD88 antagonism decrease the above effects (P<0.05). 【Conclusion】 The expressions of IL-10, IL-35 and TGF-β in gingiva CD25⁺B cells increase during periodontitis, which may be regulated by TLR4 /9-MyD88 pathway.
