Isolation of geniposide in Gardenia jasminoides was accomplished by high performance GF254 TLC and the content of the said component in the herb and its preparation determined by linear scanning at ?248nm. The method was simple and accurate.

0.05). But there was more BMP in the treated group of periodontitis than the other groups(P

0.05).Neither pruritus nor respiratory depression was noted in both groups.CONCLUSION:At an equivalent dose,Nefopam Hydrochloride showed a similar PCSA efficacy to Fentanyl after surgery but less side effect,therefore,it can be applied in postoperative PCSA.

Objective:To Study the effect of static magnetic field on the proliferation and differentiation of osteoblasts.Methods:In vitro cultured rat calvarial osteoblasts were seeded into 96-well culture plate and exposed to the different magnetic intensity field for 24,48 and 72 h respectively.MTT assay was applied to study the cell proliferation. ALP was measured by a microplate reader.Results:When the magnetic exposure time extended to 48 h or 72 h, the corresponding MTT value of osteoblasts with magnetic treatment of 40 mT or 62 mT increased obviously(P0.05). ALP activity increased after 24 h exposure to static magnetic field, the effect of static magnetic field intensity of 62 mT and 83 mT showed the strongest promotion effect(P

Objective To explore the relationship between self-efficacy and health behavior among stroke survivors.Methods Self-efficacy for Managing Chronic Disease 6-item Scale and Health Promoting Lifestyle Profile II were used to measure 96 stroke survivors’ self-efficacy and health behaviors.Pearson correlation analysis was used for the analysis of correlation.Results The mean score of overall health behaviors was (2.41±0.33).Pearson’s correlation coefficient between self-efficacy and health behavior was 0.36 (P<0.05).Conclusions The health behaviors of stroke survivors were at the intermediate or lower level and their self-efficacy was at the intermediate level.In order to help stroke survivors to improve their health behaviors,self-efficacy should be enhanced by specific health education.

Objective:To compare clinical and radiographic success rates of a modified primary root ca-nal filling ( ingredients:zinc oxide-eugenol, iodoform and calcium hydroxide, MPRCF) vs. zinc oxide-eugenol cement ( ZOE) and calcium hydroxide/iodoform paste ( Vitapex) in pulpectomized primary mo-lars at the end of 6 and 12 months, and to evaluate the degradation of materials in the root canals and in apical area. Methods:In the study, 160 primary molars from 155 children ( the average age:5. 88 ± 1. 27 years) that met the inclusion criteria were allocated to one of the three materials via block randomi-zation. A two-visit pulpectomy was performed by an investigator. The clinical and radiographic diagnoses were blindly assessed by other two investigators. Results:At the end of 6 and 12 months, the ZOE and MPRCF success rates were 100% both in clinical and radiographic evaluation. The Vitapex group showed the clinical success of 100% at the end of 6 months and 94. 5% at the end of 12 months. Radiographic evaluation for the Vitapex group showed 80 . 4% success at the end of 6 months and 60 . 7% at the end of 12 months. No statistically significant differences were noted at the end of 6 months in the three groups both in clinical and radiographic evaluation. The success rates in clinical and radiographic evaluation at the end of 12 months for ZOE and MPRCF groups were not significantly different, and better than those for Vitapex group with statistically significant difference. The completely resorb rate of excess extruded extraradicularly were 14. 3%, 100% and 71. 4% for ZOE, Vitapex and MPRCF at the end of 12 months. The rates of resorption of material at the same rate of the root were 5. 8%, 7. 2% and 40. 9% for ZOE, Vi-tapex and MPRCF at the end of 12 months. Conclusion:MPRCF, a mixture of zinc oxide eugenol and io-doform with calcium hydroxide can be used as a root canal filling material in primary teeth, taking account of the success rate and resorbing at a similar rate with the roots of the primary teeth.

Objective:To investigate the effects of Porhyromonas endodontalis(P.e)liopolysaccharide(LPS)on the expression of IL-23mRNA and protein in mouse osteoblasts MC3T3-E1 and the role of phosphatidylinositol 3-Kinases (PI3K)signaling pathway in this process.Methods:MC3T3-E1 cells were treated with different concentrations of P.e LPS for different hours,or pretreated with LY294002,a special PI3K inhibitor.The IL-23 mRNA and protein expression levels were detected by real-time PCR and Western blot respectively.Results:The level of IL-23 mRNA increased in MC3T3-E1 cells with the increase of concentration and the treatment time of P.e LPS(P <0.05).The IL-23 protein expression was increased by P.e LPS in a time dependent manner(P <0.05).The mRNA and protein of IL-23 decreased(P <0.05)after pretreatment with LY294002.Conclusion:P.e LPS can induce the expression of IL-23 mRNA and protein in MC3T3-E1 cells,and the PI3K signaling pathway may play a part in this process.

OBJECTIVE:To investigate the effect of Xuebijing injection on coagulation function and prognosis in patients with sepsis. METHODS:50 patients with sepsis were randomly divided into control group and observation group according to the hospi-talization sequence,with 25 cases in each group. Control group received conventional treatment,and observation group was addi-tionally given Xuebijing injection(50 ml added into 5% Glucose solution or 0.9% Sodium chloride solution 250 ml intravenously, bid) on the basis of conventional treatment. Treatment course lasted for 7 d. The coagulation function,APACHE Ⅱscore after 7 days of treatment and 28 d mortality were compared between 2 groups. RESULTS:After 7 d treatment,the coagulation indexes were improved significantly in 2 groups compared with before treatment,and the APACHEⅡscores were decreased significantly in both groups;the observation group were significantly better than the control group,with statistical significance (P<0.05). After followed up for 28 d,the mortality rate of 2 groups were 16% and 28%,there was no statistical significance (P>0.05). CON-CLUSIONS:Xuebijing injection can inhibit blood clotting activation,correct the coagulation disorders,and improve the sepsis se-verity.

Objective To investigate the expressions of CK17 and P63 in cervical cancer tissues,and explore the possibility of CK17 and P63 as markers of cervical cancer stem cells.Methods The expressions of CK17 and P63 in cervical squamous cancer tissues(n=55) and normal cervix tissues(n=20) were detected with immunohistochemical method.Results ①CK17 expressed in reserve cell cytoplasm in normal cervical specimens.In the cervical cancer specimens,the expression of CK17 was increased and it seemed that CK17 was stained in the margin of the cancer nest and the tumor embolus.In specimens with high grade malignant cancer or after the chemotherapy,the expressions of CK17 were increased(P
