Aim To investigate the anti-inflammatory molecular mechanism of chlorogenic acid extracted from Lonicera confusa DC in vitro.Methods PM? of a rat was segregated.MTT assay was used to detect the effects of the chlorogenic acid on PM? cells growth activities. PM? was stimulated with LPS for a prolonged period,ELISA was used to detect the level of TNF-?,IL-6 and PGE2 in the supernatant;COX-2 activity was determined by the level of PGE2 in the supernatant.After stimulating PM? with A23187 for a short time,the 6-keto-PGF1? level in the supernatant was measured by radioimmunoassay to express COX-1 activity.Results Chlorogenic acid had no inhibitive effects between 31.25 mg?L-1 and 1000 mg?L-1.The level of TNF-?,IL-6 and PGE2 in drug groups was lower than that of LPS-induced group,and the difference was significant,in a dose-dependent manner.The concentration of 50 mg?L-1 group was ineffective in the expression of TNF-?.Low concentration chlorogenic acid inhibited the expression of 6-keto-PGF1?,while high-concentration induced it.Conclusions The anti-inflammatory effect of chlorogenic acid may be related to inhibiting TNF-?,IL-6 activity and affecting exogenous AA metabolism.

Objective To compare the difference of the Cif gene expression and the inflammation markers (such as WBC and CRP et al)between mucoid and non-mucoid Pseudonmonasaeruginosa,combining with the clinical data.Methods Real-time RT-PCR was used to determine the expression level of Cif in Pseudonmonas aeruginosa and clinical data were collected to discuss the relationship among the number of WBC,the level of CRP and the Cif gene expression.Results The expression level of Cif gene in mucoid Pseudonmonas aeruginosa had a significantly higher than the non-mucoid Pseudonmonas aerugi-nosa,which was statistically significant (t=2.09,P<0.05).Specimen data collected from patients with the infection of mu-coid or non-mucoid Pseudonmonas aeruginosa showed that the number of WBC and the level of CRP were not significantly different (t=0.65,0.60,P>0.05).The data also showed that the cystic fibrosis transmembrane conductance regulator in-hibitory factor (Cif)gene expression level had little correlation with the number of WBC (a=0.095,R2=0.029).Conclusion The expression of Cif gene may works for the biofilm formation of mucoid Pseudonmonas aeruginosa,which maybe a new virulence factor to Pseudonmonas aeruginosa.

BACKGROUND:The morphological and mechanical transfers of unstable intertrochanteric fractures were complicated, so it is difficult to analyze the biomechanical characteristicsof the common experimental methods in a comprehensive way. Moreover, the high cost, long cycle and poor repeatability of common tests limit its application in biomechanics. OBJECTIVE:To analyze the biomechanical characteristics of unstable intertrochanteric fracture in different fixation ways by three-dimensional finite element analysis. METHODS:Intertrochanteric fracture locking dynamic hip fixation model (C1), Gamma nail fixation model (C2) and proximal femoral anatomical locking plate model (C3) were established. The distal end of the femur was fixed, and subjected to the hip reaction force of 2800 N and abduction muscle strength of 1 200 N. Three-dimensional finite element analysis was used to analyze the stress distribution, stress concentration and maximum displacement of unstable intertrochanteric fracture in three different fixation ways. RESULTS AND CONCLUSION:(1) Stress: the anterolateral stress and anteromedial stress of C3 were the maximum. Posterolateral stress and posteromedial stress ofC3 were the minimum. There were significant differences among the three groups (alP< 0.05). (2) Stress of fracture space: significant differences in anterolateral stress, anteromedial stress, posterolateral stress and posteromedial stress were determined in C1, C2 and C3 (P< 0.05). Anterolateral stress of C3 was significantly less than anterolateral stresses of C1 and C2 (P< 0.05). Anteromedial stress of C3 was significantly less than that of C1 and C2 (P< 0.05). Posterolateral stress of C1 was significantly larger than that of C2 and C3 (P<0.05). Posteromedial stress of C1 was significantly larger than that of C2 (P< 0.05). Posteromedial stress of C3 was significantly less than that of C1 and C2 (P< 0.05). (3) Significant differences in bone stress around the screw top were detected among the three groups (P< 0.05). Bone stress around the screw top of C3 was significantly larger than that of C1 and C2 (P< 0.05). (4) Thus, locking dynamic hip screw, Gamma nail and proximal femoral anatomical locking plate have their advantages and disadvantages for treatment of unstable intertrochanteric fracture of the femur. The appropriate internal fixation device should be selected according to the need.

Objective To evaluate the influence of orthokeratology lenses on vision,intraocular pressure and biometric measurement parameters in adolescent myopia.Methods A total of 72 adolescent myopia patients (136 eyes) with orthokeratology lens,aged 8-16 years old,in Hebei Provincial Eye Hospital from Junuary 2013 to December 2015 were randomly selected.The vision,intraocular pressure,axial length,corneal topography,corneal thickness and anterior chamber depth were observed before wearing glasses,at 1 week,1,3,6 months after wearing glasses.Results After orthokeratology wearing,the uncorrected visual acuity was obviously improved (P<0.05),the average refraction diopter was declined (P>0.05) and the non-contact intraocular pressure was decreased (P<0.05).The axial length after orthokeratology wearing had little change (P>0.05).The curvature of the patient's cornea at one week after wearing glasses was deceased (P<0.05) and the posterior corneal curvature tended towards stability.The corneal thickness at 1 week after wearing glasses had no obvious change compared with before wearing glasses(P>0.05),which at 1 month after wearing glasses was decreased(P<0.05) and which at 3,6 months after wearing glasses trended to be stabilized.The anterior chamber depth after wearing glasses had no obvious change.Conclusion Orthkeratology lens can decrease the myopia degree,increases the uncorrected visual acuity and has obvious effect for controlling adolescent myopia.The intraocular pressure and biometric measurement parameters have corresponding change after wearing orthkeratology lens.
