[Summary] This paper was to investigate whether serum angiopoietin-like protein 2 (Angptl 2) is associated with macrovascular complications in type 2 diabetes mellitus.The results showed that there were statistically significant differences in serum Angptl 2 levels among control group and groups of type 2 diabetic patients with or without carotid atherosclerosis [0.98 (0.82-1.22),3.70 (2.69-4.85),1.17 (0.76-2.47) ng/ml].Logistic regression showed that Angptl 2 was an independent risk factor of macrovascular complications in the patients with type 2 diabetes.

Objectives To study the role of IL-17 and IL-23 in non-Hodgkin lymphoma (NHL) by detecting the expression levels of IL-17 and IL-23 in peripheral blood of B-cell non-Hodgkin lymphoma patients treated by RCHOP.Methods T wenty-five patients with B-cell NHL who achieved remission after 6 to 8 cycles of R-CHOP as a NHL group,20 healthy volunteers were recruited as a normal control group.RT-PCR was used to detect the expression levels of IL-17 mRNA and IL-23mRNA in NHL patients and health volunteers.Results The expression level of IL-17mRNA andIL-23 mRNAin the patients with NHL before therapy and the patients with NHL who achieved remission was lower than that in the normal control group (P＜0.05).The expression level of IL-17mRNA andIL-23mRNA in the patients with NHL who achieved remission was higher than that in the patients with NHL before therapy (P=0.001,P＜0.05).Conclusion IL-17 and IL-23mRNA expressions are higher after treated with R-CHOP.The expression levels of IL-17 mRNA and IL-23 mRNA in NHL patients are related with prognosis and efficacy.

The transesterification reaction conditions of lard with methyl acetate with combined use of immobilized lipases as catalysts were conducted. Initially, according to single factorial experiments, the studies on Lipozyme TL IM and Novozym 435 respectively catalyzed transesterification of lard showed that the optimal parameters of transesterification reaction were: the molar ratio of methyl acetate to oil of 14∶1, 40% enzyme added based on oil weight, temperature 50℃. Combined use of Lipozyme TL IM and Novozym 435 was proposed further to improve the catalytic performance by the response surface method (RSM). Herein, a 5-level-3-factor central composite rotated design was employed to evaluate the effects of lipase loading, the proportion of the two lipases and amount of methyl acetate. The optimum conditions were as followings: 40% lipase loading based on oil weight, 50%/50% the proportion of lipases (Novozym 435/Lipozyme TL IM), and the molar ratio of methyl acetate to oil of 14∶1. And under the optimal conditions, the highest biodiesel yield of 97.6% could be attained, which was higher than the biodiesel yield with each single one of the two lipases. The results suggested that the technics of combined use of certain immobilized lipases catalyzed transesterification reaction of lard for biodiesel production with methyl acetate as the acyl acceptor could raise the FAME yield and save the production cost.

[Objective]To explore the intracellular antimicrobial activities of erythromycin,ciprofloxacin,levofloxacin,moxifloxacin against Legionella pneumophila.[Methods]The minimum inhibition concentration(MIC)of each antibiotic was evaluated by E-test method and microdilution method respectively.The minimal extracellular concentration inhibiting intracellular multiplication(MIEC)of each antibiotic was evaluated by the MTT colorimetric assay system.[Results]The MIC concentration for each drug by E-test method were:erythromycin,0.047 μg/mL;ciprofloxacin,0.38 μg/mL;levofloxacin,0.125 μg/mL;moxifloxacin,0.125 μg/mL,the MIC concentrations for each drug by microdilution method were:erythromycin,0.125 μg/mL;ciprofloxacin,0.03 μg/mL;levofloxacin,0.016 μg/mL;moxifloxacin,0.016 μg/mL.The MIEC concentration for each drug were:erythromycin,0.25 μg/mL;ciprofloxacin,0.016 μg/mL;levofloxacin,0.016 μg/mL;moxifloxacin,0.004 μg/mL.[Conclusions]Fluoroquinolones have superior activity than erythromycin in U937 cells infected with L.pneumophila.Moxifloxacin is the most potent drug among the four tested antimicrobials.Our results indicated that the MTT assay system allows comparative and quantitative evaluations of the intracellular activities of antibiotics against L,pneumophila and efficient processing of a large number of samples.

With the aging of population, cerebral small vessel disease has attracted more and more attention. A growing body of literature has confirmed that retinal vascular changes can be used as a potential marker for the prediction of cerebral small vessel disease. The retina is recognized as a window into cerebrovascular and systemic vascular conditions. Combining traditional fundus photograph and fundus fluorescein angiography with optical coherence tomography angiography, the retinal vascular system of patients with cerebral small vessel disease can be comprehensively analyzed. This paper summarizes and analyzes the application of retinal angiography technology in different image types of cerebral small vessel disease and makes a review, in order to provide reference for the early diagnosis and prevention of cerebral small vessel disease.

OBJECTIVETo study the mechanism and applicability of Bite-bumper combined with fixed appliance in treatment of lingual tipping deep bite.

METHODS14 children aged 12-16 years old with lingual tipping deep bite participated in the experiment. Bite-bumper combined with fixed appliance was used to correct the deep bite. Clinic effect was observed. Lateral cephalograms were taken before treatment and after bite opening. The related hard tissues were estimated through the cephalograms.

RESULTS1) The average duration for bite-opening with Bite-bumper and fixed appliance of 14 patients was 28 days. 2) After bite-opening, the changes in length direction of jaw (SNA, SNB, ANB) had no statistical variances. Anterior and posterior facial height (S-Go, ANS-Me) were increased. No significant changes were observed in the ratio of posterior facial height to anterior facial height (S-Go/N-Me), angle of mandibular plane (SN-MP) and Y axis. Labial incline in upper and lower incisors (U1-SN, L1-MP) and interincisa angle (U1-L1) were decreased. The posterior teeth (U6-PP, L6-MP) were extruded and the upper incisors (U1-PP) were intruded. The overbite was decreased.

CONCLUSIONBite-bumper combined with fixed appliance can be used effectively for deep bite correction and improve the short face of patients with lingual tripping deep overbite.

Objective To investigate the wall shear stress(WSS) in the common carotid artery of type 2 diabetes mellitus(DM) patients,and analyzed the spatial distribution of WSS by using quantitative visualization of blood flow shear stress analysis software.Methods Eighteen male type 2 DM subjects were enrolled as DM group and 18 age-matched healthy subjects were selected as control group.None of the participants was hypertensive,hyperlipidemic or a cigarette smoker.Intimal-medial thickness (IMT),number and size of plaques in the common carotid artery were evaluated by high-resolution echo-Doppler.Color Doppler flow images of common carotid arteries in the two groups were extracted from DICOM files.WSS in the common carotid arteries was calculated by shear stress visualization quantitative analysis software,and the corresponding spatial distribution maps of WSS were designed.Results WSS of the common carotid arteries in the control group were ranged from 4 to 14 dyne/cm2.WSS of the common carotid arteries in the DM group were ranged from 2 to 8 dyne/cm2.Compared to mean WSS value [(6.96 ± 1.17)dyne/cm2] of common carotid arteries in the control group,mean WSS value [(3.14 ± 0.79)dyne/cm2] of common carotid arteries in the DM group was significantly lower (t =9.380,P =0.000).Six diabetic participants had a plaque in one carotid artery and no lesions in the contralateral carotid.Among these subjects,mean WSS was significantly lower in the side with lesion (t =7.324,P =0.000).Therefore,IMT of common carotid arteries in participants was significantly inversely related to WSS (r =-0.76,P ＜0.01).Conclusions The common carotid arteries of DM patients are more prone to atherosclerosis which is associated with reduction of WSS.The hemodynamic profile might represent an additional factor contributing to the increased prevalence and severity of carotid atherosclerosis in diabetic patients compared with general population.
