Objective To evaluate inhibitory effects of the Chlamydiaphage phiCPG1 capsid protein Vp1 on Chlamydia psittaci strain guinea pig inclusion conjunctivitis (GPIC) and Chlamydia trachomatis (Ct) serovar E,and to provide new ideas for the treatment of Ct infection.Methods The Chlamydiaphage phiCPG1 capsid protein Vp1 was expressed in Escherichia coli BL21 transfected with the recombinant plasmid Vp1-pET30a (+),identified by Western blot analysis and purified by using dialysis bags.Bicinchonininc acid (BCA) assay was performed to determine the concentration of Vp1 protein.GPIC and Ct serovar E strains were both classified into 4 groups to be firstly incubated with Vp1 protein (Vp1 group),Tris-glycine solution (Tris group),S protein (S group) or Dulbecco's Modified Eagle Medium (DMEM,DMEM group) at room temperature for 3 hours,then were used to infect Hela cells followed by 72-hour (GPIC) or 48-hour (Ct serovar E) culture with the presence of Vp 1 protein (Vp 1 group),Tris-glycine solution (Tris group),S protein (S group) or DMEM (DMEM group).Subsequently,immunofluorescence staining was conducted to observe and count chlamydial inclusions.Results The number of GPIC inclusions was significantly different between the 4 groups after 72-hour culture (F=476.632,P＜ 0.05),and lower in the Vp1 group (5.0 ± 1.5) than in the Tris group (24 ± 1.2,P＜ 0.05),S group (25 ± 1.7,P＜ 0.05) and DMEM group (25 ± 1.5,P＜ 0.05),but insignificantly different between the latter 3 groups (P ＞ 0.05).Compared with the DMEM group,the Vp1 group showed a significant decrease of 80.2％ ± 3.99％ and 77.2％ ± 1.79％ in the number of GPIC and Ct serovar E inclusions respectively,with no significant difference in the inhibitory effect of Vp1 on GPIC versus Ct serovar E (t =2.057,P ＞ 0.05).Conclusion The phiCPG1 capsid protein Vp1 can obviously inhibit GPIC and Ct serovar E infections to a similar degree.

Objective To compare the effect of enteral nutrition liquid with different dietary fiber content on serum protein in patients with stress hyperglycemia.Methods A total of 90 patients with stress hyperglycemia were randomly divided into three groups:enteral nutritional suspension (SP) group (Peptisorb),enteral nutritional suspension (TPF-FOS) group (Jevety) and enteral nutritional suspension (TPF-D) group (Glucerna),each group consisting of 30 patients.In the three groups,prealbumi (PA),serum albumin (ALB),retinol binding protein (RBP),transfer-rin (TRF) and hemoglobin (Hb) were continuously measured on the 1st,2nd,3rd,4th,5th,6th and 7th day.Data were analyzed by SPSS 15.0.Variances on time and group were analyzed by repeated measures of general linear model.Results The PA,ALB,RBP,TRF and Hb were significantly different among Peptisorb group,Jevety group and Glucerna group (P＜ 0.05).The PA,ALB and Hb which were determined in different time,were not significantly impacted by Peptisorb,Jevety or Glucerna,and not significantly changed with time.The RBP and TRF which were determined at different time,were not impacted by Peptisorb,Jevety or Glucema,but time× group from RBP and TRF which were determined in different time,were significantly impacted in Peptisorb group,Jevety group and Glucerna group (P＜ 0.01).Conclusion The content from different dietary fiber significantly affects serum protein in patients with stress hyperglycemia,and TPF-D has the most significant effect on serum protein.

Objective The aim of this study was to investi-gate the changes of brain function in patients with drug-naive idiopath-ic epilepsy ( DNIE ) using resting-state functional MRI ( rs-fMRI ) amplitude of low-frequency fluctuation ( ALFF) , analyze the correlation of abnormal brain regions with the clinical variable ( disease course) , and gain a deeper insight into the pathophysiological mechanisms of idiopathic epilepsy. Methods This study included 25 cases of DNIE (15 males and 10 females) and 34 cases of drug idiopathic epilepsy (DIE, 22 males and 12 females).Another 25 healthy volunteers matched with the DNIE patients in sex, age, education and handedness were recruited as normal controls.The rs-fMRI data obtained from all the subjects were processed, subjected to ALFF analysis, and compared among the DNIE, DIE, and nor-mal control groups.The correlation was evaluated between the ALFF statistical brain mapping and the course of disease. Results Obvious differences were found in ALFF among the DNIE, DIE and control subjects.Compared with the normal controls, the DNIE pa-tients showed increased ALFF in the right inferior temporal gyrus, right lingual gyrus and right cuneus, but decreased ALFF in the right insula, left hippocampus, right midbrain, right middle frontal gyrus, left anterior cingulated gyrus, left middle cingulate gyrus and right inferior parietal lobule.In comparison with the DIE patients, those of the DNIE group exhibited increased ALFF in the left inferior occipital gyrus, right middle occipital gyrus and left middle occipital gyrus, but decreased ALFF in the right inferior frontal gyrus, left insula, right superior temporal gyrus and right middle frontal gyrus.In the DNIE patients, the disease course was found to be correlated positively with ALFF in the right cerebellum posterior lobe, left cerebellar tonsil, right lingual gyrus, left orbital gyrus, left middle oc-cipital gyrus, left corpus callosum, left caudate nuclear, left superior frontal gyrus, left medial frontal gyrus, right precuneus and left middle frontal gyrus, but negatively with ALFF in the right parahippocampal, right superior temporal gyrus, left superior temporal gyrus and right post-central gyrus. Conclusion The ALFF of resting-state cerebral function is abnormal in DNIE patients.The correlation between ALFF and the clinical variable ( disease course) provides a new insight into the pathophysiological mechanisms of epilepsy.
