Objective: To study the affection of Diallyl trisulfide on cultured human colon carcinoma cell line HT-29 and its mechanism. Methods: The viability of cells after various treatments were determined using the method of MTT. Flow cytometry were used to analyze the change of cell cycle and Bcl-2, Bax levels. Results: The proliferation of human colon carcinoma HT-29 cells were inhibited by Diallyl trisulfide. The inhibition was associated with dose and time dependence. Flow cytometry results showed that: 1) When cells were treated with Diallyl trisulfide at the concentration of 10 ?g/mL for 12 h and 24 h, the percentage of G0/G1 phase cells was decreased and that of G2/M phase cells was significantly increased compared with those in the control group.2) Diallyl trisulfide down regulated Bcl expression, while up-regulated bax expression. Conclusions: It was suggested that Diallyl trisulfide inhibited HT29 cell proliferation. And these were associated with arrest of cell cycles and down regulation of Bcl2/Bax ratio.

To observe the clinical results of innercapsular phacoemulsification with primary intraocular lens ( lOL ) implantation in the treatment of lens dislocation.METHODS: A total of 23 cases ( 23 eyes ) of lens dislocation ( lla and llb ) were underwent innercapsular phacoemulsification combined with primary lOL implantation. lOL implantation were underwent during operation, the complications of intraoperative and postoperative, postoperative vision, intraocular pressure ( lOP ) , corneal endothelial cell, lOL location were analyzed.RESULTS: The operations were successfully completed for all patients in accordance with the pre - surgery program; lens nucleus or its fragments did not crash into the vitreous cavity; 20 cases of corneal edema and 17 cases of lOP presented at the first day after surgery, the deviation or displacement of lOL and serious complications such as retinal detachment were not appeared. At the first week postoperation, the average lOP was 15. 81 ± 2. 10mmHg, with statistically significant differences when compared with the preoperative ( P<0. 01 ) , the visual acuity in all eases increased, with statistically significant differences when compared with the preoperative ( P < 0. 01 ). Corneal endothelial cell density and percentage of hexagonal cells decreased, the variation coefficient increased in first week of postoperative, with no statistically significant differences when compared with the preoperative (P>0. 05) CONCLUSlON: lnnercapsular phacoemulsification combined with primary lOL implantation in the treatment of the whole lens dislocation (‖a and ‖b ) can restore function in patients with diplopia and control lOP effectively, reduce corneal endothelial cell damage, which is an effective method to treat the whole traumatic lens dislocation.

Objective Aliginic sodium diester(ASD) liposome was prepared and its aggregation stability was evaluated.Methods ASD liposome was made by reverse phase evaporating method from egg yolk lecithin,compared with blank liposome,the size distributions and mean particle diameters of ASD liposome and blank liposome were measured respectively before and after 40 hours heating under 37℃.Results Under the condition of n(PC)∶n(CHOL) = 1∶1,the mean size diameter of ASD liposome was 4.24?m.The mean size diameter of ASD liposome changed only 0.26?m after cultivation,however,the value of blank liposome was 1.35?m.Conclusion ASD loaded in the liposome enhanced the physical stability of the liposome.

Objective This study aimed to construct an index system for nurse performance appraisal based on the quantity,quality,efficiency and technology in holistic nursing mode.Methods Expert interviews and Delphi expert enquiry were used to complete the construction of index system,and SPSS17.0 was used to do data statistics and reliability analysis.Results The nurse performance appraisal index system was constructed which contained 4 level-Ⅰ indicators such as level coefficient,nursing workload scores,nursing quality scoring rate and reward amount and 12 level-Ⅱ indicators.The calculation method of each part was also established.The expert positive coefficients were 94.3% and 100.0% respectively,the authority coefficients were 0.83 and 0.84,the importance and feasibility mean scores of every index were 4.27-5.00 and 4.26-4.94,and coefficients of variation were 0.00-0.26 and 0.05-0.26 in 2 rounds of enquiry.The importance of level-Ⅰ or level-Ⅱ indicators and operability coordination coefficients were 0.13-0.43,the significance test showed P < 0.05.Conclusions The design of each dimension of the index system gives full consideration to nurse post management,hierarchical using,the nurse in charge of the patient,grading nursing care and many other factors.Representative of key indicators is strong,and it can reflect the distribution concept that more payment for more contributions,best's best reward and rewarding the good and punishing the bad.

BACKGROUND: The osteogenesis effects of concentrated growth factors (CGF) gel have been studied, but little has been reported on CGF liquid.OBJECTIVE: To explore the bone mass changes after CGF is used in the dental implant surgery with guided bone regeneration (GBR) in patients with upper anterior tooth labial bone defect, and to evaluate the effect of CGF liquid combined with Bio-Oss bone meal on bone augmentation.METHODS: Fifty patients with single anterior tooth labial bone defect were enrolled and randomly divided into experimental and control groups (n=25 per group). Patients in both groups underwent dental implant surgery with GBR.CGF liqiud, Bio-Oss bone meal and biological membrane were used in the experimental group, and Bio-Oss bone meal and biological membrane used in the control group.RESULTS AND CONCLSUION: All patients healed well according to the successful criteria. Six months postoperatively,there was no significant difference in the thickness changes of labial bone between two groups (P > 0.05). From 6 months to 12 months after operation, the thickness changes of labial bone in the experimental group was significantly less than that in the control group (P < 0.05). Our findings indicate that CGF liquid combined with Bio-Oss bone meal makes good effect on dental implantation of patients with anterior tooth labial bone defect. CGF liquid also contributes to reduce the labial bone resorption of the implant after functional loading.

Objective To study the effects of Fluvastatin on the expression of intercellular adhesion molecule-1 (ICAM-1) in human umbilical vein endothelial cells (HUVECs) induced by C-reactive protein (CRP). MethodsThe HUVECs were primary cultured. HUVECs from third to sixth generations were stimulated with different concentrations CRP and at different times. Then the cells were treated with Fluvastatin in different concentration of 10-7,10-6 and 10-5mol/L. The content of ICAM-1 protein was detected with ELISA, the mRNA expression of ICAM-1 was evaluated by RT-PCR. Results In the control group, HUVECs produce ICAM-1 protein and mRNA in low concentrations. In CRP group, the content of ICAM-1 protein was increased significantly (P

Objective:To develop a convenient,economical and stable model of acute lung inflammation in mice.Methods:BALB/c mice were inhaled intranasally with 50 ?L of LPS(1 g/L) or sterile PBS,and sacrificed at different time points after being anaesthetized.The bronchoalveolar lavage fluid(BALF) was collected,and the lungs were separated and homogenated or embedded and sliced to 5 ?m sections,which were then stained by HE to determine the severity of inflammation.The inflammatory cell infiltration in bronchoalveolar lavage was counted and IL-1?,the pro-inflammatory cytokine,measured by ELISA in lung homogenate and BALF.Results:The data showed that administration with 50 ?g of LPS(1 g/L) for 2 h resulted in significant inflammation in the lung.LPS mainly stimulated the recruitment of neutrophils within 24 h.And LPS was a quick revulsant of IL-1? production in BALF and in lung tissue between 4 and 24 h.Macrophages and lymphocytes recruited after 1 day,and sustained for at least 3 days.Conclusion:The results indicate that intranasal administration of LPS can induce a rapid and stable acute inflammatory model in mice.
