Objective:To investigate the impact of recombinant flagellin targeting TLR5 and NLRC4 simultaneously or respectively on innate immune cells in mice. Methods: Induction,expression,purification and identification of recombiant FliC,which were FliC(activating both TLR5 and NLRC4);FliCΔ90-97(unable to activate TLR5),FliC-L3A(unable to activate NLRC4),FliCΔ90-97:L3A(unable to activate both TLR5 and NLRC4). The mice were divided into five groups,namely group FliC,FliC-L3A,FliCΔ90-97,FliCΔ90-97:L3A and PBS,which were injected with 100μl PBS or 10μg recombinant flagellin intraperitoneally,three mice in each group. 12 h later,the mice were executed using dislocation of cervical vertebra and the splenic and peritoneal cells were isolated. The spleen was grinded into single-cell suspension. The proportion of neutrophils,NK cells,DCs and the expression level of CD80 and CD86 on DCs were evaluated with flow cytometry. Results:Group FliC,group FliC-L3A and group FliCΔ90-97 shared the similar proportion of neutrophils in peritoneal cavity ( P>0. 05 ) , and all of which were significantly higher than group PBS and group FliCΔ90-97 ( P<0. 01),and NK cells also showed the similar trend. Compared with group FliCΔ90-97 and FliCΔ90-97:L3A,the mean fluorescence intensities(MFIs) of CD80 and CD86 in group FliC and FliC-L3A increased significantly(P<0. 01). The proportion of Treg in spleen was highest among all groups. Conclusion:Activation of TLR5 and NLRC4 had similar chemotaxis of neutrophils and NK cells. The ex-pression of CD80 and CD86 on DCs were upregulated after stimulation by flagellin and TLR5-dependent. Activation of TLR5,but not NLRC4,increased the proportion of Treg in spleen.

BACKGROUND: Peritonitis is the common detective complications at the end-stage of renal failure patients during continuous ambulatory peritoneal dialysis (CAPD) treatment, which easily repeatedly occurred if not handled properly. Although the plumbing designs of peritoneal dialysis have done a lot of effort and improved in recent years, it still hard to avoid. OBJECTIVE: To explore the relative factors and treatments of infectious peritonitis complicated with CAPD. METHODS: Totally 115 cases received CAPD were selected, including 55 males and 60 females, aged (56.2?.7) years. 68 cases of which were suffered infectious peritonitis, aged (58.5?.3) years. All received a (30.3?.5)-month CAPD treatment. The relative factors such as the nutrition situation, whether complicated with diabetes mellitus or not, culture background, domestic environment, whether operating by special person and so on were investigated, and the relationship between those factors and infectious peritonitis were analyzed. The pathogen method was used to check pathogenic bacteria, and those patients were treated with irrigation of abdominal cavity and antibiotics in two ways, that is, systemic and intra-abdominalcavity. Hemodialysis instead of CAPD was used in those infectious peritonitis patients.RESULTS AND CONCLUSION: Those patients with good nutrition situation, higher culture background, better domestic environment, and operating by special person had low chances to infect peritonitis. And those patients with diabetes mellitus had high chances to infect peritonitis. Treatments of abdominal cavity and anti-infection in two ways-systemic and intra-abdominal cavities were effective to those infectious peritonitis patients. Gram-positive bacteria were the most common pathogen, which were susceptive to vancomycin and cefazolin. If the pathogen was gram-negative bacteria, etimicin sulfate, amikacin, and imipenem cilastatin could be selected. Infectious peritonitis complicated with CAPD affected by many factors. CAPD patients should be provided better nutrition and domestic situation. Also patients should operate in aseptic ways. Doctors should choose proper patients who can operate CAPD right.

AIM: To observe the therapy effect of standard prescription on ametrop amblyopia in hyperopic children.
METHODS: This study included 270 cases ( 54 eyes ) with complete data, and followed up 24mo. All the amblyopic children were given standard prescription and were divided into progressive addition glass group, under corrected group and full corrected group. And all were observed for their therapy effect and the average healing time in low hyperopic, moderate hyperopic and high hyperopic children with ametropic amblyopia respectively.
RESULTS: In low hyperopic children, the difference of the therapy effect of the three corrected methods were insignificant in two years. The meam cure time of the three corrected methods were ( 7. 33 ± 2. 11 ) mo in progressive addition glass group;(9. 0±3. 71)mo in under corrected grope;(12. 5±5. 17) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=1. 66, P>0. 05) was statistically insignificant; the difference between progressive addition glass group and full corrected grope ( t = 3. 92, P < 0. 01 ) was statistically significant; the difference between under corrected grope and full corrected grope ( t = 2. 33, P < 0. 05 ) was statistically significant. In moderate hyperopic chileren, the differences of the therapy effect of the three corrected methods were significant in two years (χ2=6. 75;P<0. 05). The difference between progressive addition glass group and under corrected grope (χ2 = 6. 3; P < 0. 01 ) was statistically significant; the difference between progressive addition glass group and full corrected grope (χ2=8. 1;P<0. 005) was statistically significant. The mean cure time of the three corrected methods were ( 14. 0±4-87) mo in progressive addition glass group; ( 16. 93±4-58)mo in under corrected grope; (17. 93±4. 42) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=2. 88, P<0. 01) was statistically significant; the difference between progressive addition glass group and full corrected grope ( t= 3. 9, P<0. 01 ) was statistically significant;the difference between under corrected grope and full corrected grope ( t = 1. 01, P > 0. 05 ) was statistically insignificant. In high hyperopic amblyopic children, the difference of the therapy effect and the healing time of the three corrected methods were insignificant in two years. (χ2=2. 43, P>0. 05. t=1. 49, P>0. 05;t=1. 46,P>0. 05;t=1. 11, P>0. 05).
CONCLUSION:Under standard prescription, application of progressive multifocal glasses provides a new effective treatment for ametropic amblyopia in hyperopic children, and makes up the deficiency of the whole straightening and under correction in clinical treatment.

Objective:To explore the impact of TLR5 and NLRC4 activation on the proliferation of different breast cancer cell lines,MCF-7 and MDA-MB-23 i.Methods:Induction,expression,purification and identification of recombiant flagellin,including FliC (activating both TLR5 and NLRC4),FliC△90-97 (unable to activate TLR5),FliC-L3A (unable to activate NLRC4),FliC△90-97:L3A (unable to activate both TLR5 and NLRC4).Using different concentration of recombinant flagellin to stimulate MCF-7 and MDA-MB-231 cell lines,72 h later,the proliferation of tumor cells were detected with CCK8.We also used soft AGAR forming experiments to detect the inhibition ratio of recombinant flagellin on breast cancer cell lines.Briefly,1 000 cells were plated in the 6-well plate,then stimulated with 1 μg/ml recombinant flagellin,14 days later,the number of cloning were counted after crystal violet staining.Results:After stimulation with four recombinant flagellins at the concentration of 0.1 μ,g/ml,the inhibition ratio on MCF-7 reached 30％,and FliC△90-97 were dose-dependent on the inhibition of MCF-7 proliferation.At the concentration of 1 μg/ml,FliC-L3A which only activated TLR5 showed stronger inhibition ratio than FliC.FliC△90-97:L3A which did not activate both TLR5 and NLRC4 also inhibited the proliferation of MCF-7.After adding transfection reagent,four recombinant flagellins showed inhibition effect on MDA-MB-231.Conclusion:Flagellin can inhibit the proliferation of MCF-7 and MDA-MB-231,and the mechanism of inhibition on the proliferation were not TLR5 and NLRC4 pathway dependent.There might exist new mechanisms to explain this phenomenon.

Objective To evaluate neurodevelopmental outcome of very preterm(gestational age ＜ 32 weeks) and very low birth weight infant (VLBWI) (weight ＜ 1 500 g) and to examine the effectiveness of an early intervention program till 12 months corrected age.Methods Seventy followed-up very preterms and VLB-WI in Jinan Maternity and Childcare Hospital were enrolled in this study from January 2012 to and were divided into two groups by birth weight.All infants received 20 items of behavioral neurological assessment at 1 to 12 months corrected age and tested mental and psychomotor development with the use of CDCC at 6,12 months corrected age.The preterms who were abnomal in the 20 items of behavioral neurological assessment would receive early intervention (including kinesitherapy, physiotherapy, cereal circulation therapeutic equipment) by physiotherapists and their parents who received an intervention program training and were strongly encouraged to participate in the intervention sessions.The intervention method was adjusted according to the neurological assessment.The SPSS statistical software package for Windows, version 15.0, was used to run Fisher's exact test and t-test on the data presented,and P value of less than 0.05 was regarded as statistically significant.Results The average gestational age of infants was (30.4 ± 1.8) weeks,and average birth weight (1 463.7 ± 307.5) g.The incidence of extrauterine growth restriction was 57.1％ at first follow-up.The incidence of neurodevelpmental impairment NDI) and cerebral palsy tendency at 6 corrected months were 14.3％ ,8.6％ respectively.At 12 months corrected age,the incidence of NDI decreased to 2.9％ and cerebral palsy to 2.9％.There was significant difference in the incidence of NDI between 6 and 12 corrected months.There was no significant difference in the incidence of psychomotor developmental index ＜ 70, mental developmental index ＜ 70, NDI and cerebral palsy between the two groups.Conclusion The early intervention program can improve VLBWI neurodevelopmental outcomes at 12 months' corrected age and reduce the incidence of cerebral palsy.

Based on target cycling amplification and 3 ,4 ,9 ,10-perylenetetracarboxylic dianhydride derivative functionalized singal probe, an ultrasensitive electrochemiluminescence ( ECL) sensor was designed for the detection of lead ions. The hairpin substrate DNA was immobilized on the electrode through molecular self-assembly. In the presence of Pb2+and DNAzyme, the substrate was cleaved with single strand DNA fragments left on the electrode surface. Meanwhile, the target and DNAzyme was released for another cleaving circularly. As a result, the single strand DNA fragments hybridized with the assist hairpin probe H1, which leaded to the fabrication of H2 labeled with the 3 , 4 , 9 , 10-perylenetetracarboxylic dianhydride derivative functionalized hollow gold nanoparticles. With the increasing concentration of Pb2+, much more signal probe was been captured and the ECL signal of the biosensor in peroxydisulfate ( S2 O2-8 ) solution would increase. An ECL assay demonstrates that the sensor has a good linear response to Pb2+ concentration in the range of 1í10-12 mol/L-1í10-6 mol/L, with a detection limit of 1í10-12 mol/L. The fabricated sensor shows good selectivity toward Pb2+against other common metal ions.

Objective To observe the clinical efficacy of Tanreqing Injection combined with levofloxacin injection in treatment of acute episode of chronic bronchitis and its effect on bacterial clearance rate. Methods Totally 66 patients were randomly divided into treatment group and control group (33 cases for each). Both groups were given expectorant and antispasmodic treatment. The treatment group was given Tanreqing Injection combined with levofloxacin injection, while the control group was given levofloxacin injection only. The treatment course was 12 days. The clinical symptoms, signs, and sputum culture before and after treatment were observed. The clinical efficacy and the bacterial clearance rate of the two groups were compared. Results The markedly effective cases and the effective cases in the treatment group were 15 and 29 respectively, and those in the control group were 7 and 21 respectively, with statistical significance (P<0.05). The bacterial clearance rate was 89.5% (17/19) in the treatment group, while 55.6%(10/18) in the control group, with significant difference (P<0.05). Conclusion Acute episode of chronic bronchitis treated by Tanreqing Injection combined with levofloxacin injectcion is more effective than levofloxacin injection only.
