Objective To study the correlations between the levels of inhibition C (Cys-C), glycosylated hemoglobin A1c (HbA1c) and the coronary lesion. Methods 184 patients were divided into the coronary heart disease (CHD) group (n = 113) and the control group (n = 71) according to coronary angiography. The correlations between the level of Cys-C, HbA1c and Gensini score and coronary vessel lesions were investigated. Results The levels of Cys-C and HbA1c of CHD group were significantly higher than the control group (P<0.05). The levels of Cys-C and HbA1c were positively correlated with Gensini score (r = 0.452, 0.570; P < 0.05). The levels of Cys-C and HbA1c were positively correlated with coronary vessel lesions (P<0.001). Multivariate analysis showed Cys-C and HbA1c were significantly associated with Gensini score (β = 0.221, t = 2.516, P < 0.013;β=0.525, t = 6.342, P < 0.001). There was no significant correlation between the level of Cys-C and Gensini score in the subgroup A (r = 0.102, P = 0.418), and the level of Cys-C was positively correlated with Gensini score in the subgroup B (r=0.440, P<0.002). Conclusions The levels of Cys-C and HbA1c are independently associated with the severity and the vessels of the coronary stenosis. Clinically, the joint detections of the levels of Cys-C and HbA1c are a higher predictive value for coronary artery lesions.

Objective To investigate the performances and characteristics of femoro-acetabular impingement (FAI)on MSCT. Methods Hips jointed MSCT scans of 109 cases (as case group)and the other 120 cases (as control group)were analyzed retrospec-tively,to analyze the anatomy and osseous abnomality of FAI.Alpha angle,offset,CE angle were measured.The data were tested by using t test and ANOVA test.Results There were 57 cases of osseous protuberance at the femoral head and neck joint,26 cases of the offset reduction,17 cases of over-coverage acetabulum,41 cases of over-deep acetabulum,20 cases of acetabular retroversion,57 cases of subcortical cystic degeneration at the femoral head and neck joint and 22 cases of subchondral cystic degeneration at the ace-tabulum margin.Significant statistical differences were found between case group and control group in alpha angle value,offset and CE angle (P<0.05).Multiple comparisons demonstrated that except results between the value of alpha angle of Cam-type and Mixed-type(P=0.071),Pincer-type and the control group(P=0.083)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrated that except result between the value of offset of Cam-type and Mixed-type(P=0.561)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrate that except results between the value of CE angle Pin-cer-type and Mixed-type (P=0.444),Cam-type and the control group (P=0.236)with no statistical significance,the differences be-tween any other two groups reached statistical significance (P<0.05).Conclusion Different type of FAI has its unique anatomical features.Alpha angle,offsetand CE angle for the diagnosis of FAI have important reference values.

Objective To study the visual attention of mild cognitive impairment patients (MCI)by eyes movement training. Meathods 48 mild cognitive impairment patients were divided into eye movement training group,finger training group and untreated control group by single-blind randomized block method. Then they were trained respectively three months. Event-related potentials (ERPs) were used to measure the face recognition of them before and after training. The amplitude and latency of P3b elicited by target stimuli and P3a elicited by new stimuli of the three said groups were compared and contrasted. Results After training,the amplitude of P1 elicted by novelty stimulus were larger in eye movement training group( (6.78 ± 1.55 ) μV) and in finger training group ( ( 5.43 ± 1.47 ) μV) than untreated control group ( ( 3.09 ± 0.98 ) μV) significantly, especially in the frontal area. The amplitude of P1 elicted by target stimulus were larger in eye movement training group( (6.75 ±2.01 ) μV)than in finger training group( (4.12 ± 1.33 )μV)and untreated control group( (3.45 ± 1.01 )μV)significantly, especially in the frontal area. The amplitude of P3a were larger in eye movement training group( ( 10. 19 ± 3.09)μV ) than in finger training group ( ( 7.57 ± 2.66 ) μV ) and untreated control group ( ( 6.06 ± 2.03 ) μV ) (P ＜ 0.05,P＜0.05) significantly,especially in the frontal area. The latency of P3a were earlier in eye movement training group( (390.67 ±55.03 ) ms) compared to finger training group( (428.55 ± 48.68 ) ms) and untreated control group( (435.89 ± 59.21 )ms)significantly, especially in the frontal region and central parietal area. Conclusion Eyes movement can improve the MCI patients' non-selective attention function, especially in frontal area.The finger execrises have no significant effect on visual attention.

Objective To summarize the clinical features,treatment and prognosis of bullous systemic lupus erythematosus (BSLE).Methods Clinical data were collected from 6 cases of BSLE between May 2009 and September 2015,and were analyzed retrospectively.Results Among the 6 patients,2 were male and 4 were female.The mean age of onset was 34 years.All the 6 patients presented with tense blisters and bullae arising on an erythematous base or normal skin,which were arranged in an annular pattern in 3 patients.The SLE Disease Activity Index (SLEDAI) score was ＞ 4 in all the 6 patients.Histopathological examination showed subepidermal blisters or fissures in all the patients.Direct immunofluorescence (DIF) revealed continuous linear deposition of immunoglobulin G (IgG),IgM and IgA in all the patients,linear deposition of C3 in 4 patients,and linear deposition of Clq in 2 patients at the basement membrane zone (BMZ).All the 6 patients were treated with oral glucocorticoids and hydroxychloroquine,and 2 patients were additionally treated with cyclophosphamide.During the follow-up period,adverse reactions to different extents were observed in the 6 patients.Conclusions BSLE mainly occurs in young and middle-aged people.Histopathologically,subepidermal blisters or fissures can be observed with linear deposition of IgG,IgM,IgA,or C3 along the basement membrane zone on DIF.

Objective To investigate the predictive value of neutrophil and lymphocyte ratios (NLR)for the prognosis in patients with acute cerebral infarction. Methods From January 2014 to December 2015,307 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,the Fifth Affiliated Hospital of Zhengzhou University were enrolled retrospectively,including 80 females and 227 males. They were divided into ether a good prognosis group (n = 195)or a poor prognosis group (n = 112)according to the scoring criteria of the modified Rankin scale (mRS). The age,gender, past medical history,National Institutes of Health stroke scale (NIHSS)score were documented on admission. The NLR values were calculated according to the neutrophil and lymphocyte counts on admission. Logistic regression analysis was used to analyze the influencing factors of poor prognosis of acute cerebral infarction. The receiver operating characteristic curve (ROC)was used to evaluate the predictive effect of the NLR level on patients with acute cerebral infarction on admission. Results (1)Compared with the good prognosis group,the age,incidence of recurrent cerebral infarction,NIHSS score on admission, NLR levels on admission in the poor prognosis group were higher. There were significant differences between groups (69 ± 12 years vs. 62 ± 14 years,25. 0% [28 / 112]vs. 14. 4% [28 / 195],5. 00 [3. 00, 9. 00]vs. 3. 00 [1. 75,5. 00],and 3. 66 [2. 62,7. 91]vs. 2. 47 [1. 94,3. 40];all P < 0. 05). There were no significant differences in other baseline data and clinical characteristics between the groups (all P >0. 05). (2)Multivariate logistic regression analysis showed that the increase of the age,NLR level on admission,and increased NIHSS score on admission,were independent risk factor for poor prognosis (OR 1. 030,1. 148,and 1. 427,respectively,95% CI were 1. 007 -1. 053,1. 059 -1. 246,and 1. 247 -1. 634, respectively;all P < 0. 05). (3)The diagnostic cut-off value of the NLR level on admission for the poor prognosis in patients with acute cerebral infarction was 2. 84. Its sensitivity was 69. 6% and specificity was 64. 6% . Conclusion The increase of the NLR level on admission had certain reference function on the poor prognosis in patients with acute ischemic stroke.

BACKGROUND: A few mesenchymal stem cells (MSCs) can be found in peripheral blood.OBJECTIVE: To isolate rabbit peripheral blood MSCs and induce its differentiation into osteoblasts.DESIGN, TIME AND SE'I-I'ING: The cytological in vitro study was performed at the Central Laboratory of Shangdong Provincial Hospital from June to December 2008.MATERIALS: A total of 6 New Zealand rabbits were purchased from Shandong Academy of Agricultural Sciences. α-MEM and L-DiEM were bought from Hyclone.METHODS: Full-thickness skin (3 cm×3 cm) (dorsal muscular layer was left) was incised at various sites of rabbit back, every 3days. Incised skin was dressed following orthotopic transplantation. Each rabbit received four consecutive wounds. Peripheral blood was collected from femoral vein before injury and 1 week after injury. MSCs were harvested from peripheral blood by density gradient cantrifugation. MSCs were divided into 2 groups, which were respectively incubated in α-MEM supplemented with 10% fetal bovine serum and L-DiEM. Cells at passage 2 and 1 ×105/cm2 were incubated in a 12-well plate and induced with H-DiEM containing osteogenic inductor.MAIN OUTCOME MEASURES: The following parameters were measured: cell morphology before and after injury; colony forming efficiency of MSCs; outcome of osteogenic induction.RESULTS: Following primary medium change and before injury, obtained cells were normal. Twenty-four hours following incubation and after injury, MSCs were spindle or polygonal, and adhered to the wall. 5-6 days later, cell colonies appeared.Compared with the L-DiEM group, the number of primary culture colony formation in α-MEM group was significantly greater (P < 0.05). Peripheral blood MSCs were spindle, tdangle or polygonal, with the presence of processes, 2-3 nuclei and cell division phase, and slowly proliferated following osteogenic induction. At day 7 after differentiation of MSCs into osteoblasts, positive rate of alkaline phosphates was above 80%. At day 21, calcium deposition was detected by Alizarin Red S (positive staining).CONCLUSION: MSCs could be harvested from peripheral blood of wounded rabbits, with characteristics of osteogenic differentiation, α -MEM was more suitable than L-DiEM for peripheral blood MSCs to growin vitro.

Objective:To investigate the immediate bond strength and surface structure of resin and the tooth enamel which treated by cold plasma.Methods:In the study,40 bovine incisors were divided into two equal parts.In this sense,all enamel adhesive samples were prepared and then randomly divided into 4 groups(n =20).group 1:acid +single bond 2 +resin composite(control group);group 2:beyond bleaching+acid+single bond 2+resin composite;group 3:treated by cold plasma for 5 minutes+acid+single bond 2+resin composite;group 4:treated by cold plasma for 5 minutes+single bond 2+resin composite.Single bond 2 bonding system and Filtek Z250 resin were used in this experiment.The shear bond strength was tested by universal testing machine.The surface of the enamel in different processes was observed by scanning electron microscope (SEM).Statistical analyses by the single factor analysis of variance and multiple pairwise comparisons were performed with SPSS 1 7 .0 .Results:The shear bond strength of group 4 (8.60 MPa)was significantly lower than that of the other three groups (P<0.05). The shear bond strength of group 2 (1 7.89 MPa)was higher than that of group 4,but lower than group 1 and group 3 (P<0.05).There was no significant difference between group 1 (34.82 MPa)and group 3 (34.69 MPa).Scanning electron microscope indicated that the enamel treated by cold plasma had slight molten form,which was different from etched enamel surface.The fractured surface of group 3 was mix fracture,which was similar to the control group (group 1 ).Conclusion:Compared with the conven-tional clinic bleaching,immediate bond strength of resin-enamel that treated by cold plasma has not been affected.

Objective To observe the analgesic and sedative effects of oxycodone combined with dexmedetomidine and its effects on respiratory and cardiovascular functions during endotracheal intubation guided by fiberoptic bronchoscope at conscious state.Methods Forty patients with endotra-cheal intubation difficulty were randomly divided into sulfentanil group and oxycodone group.An initial induction dose of 1 μg/kg dexmedetomidine was given followed by an maintaining infusion of 0.2 μg·kg-1 ·h-1 in sulfentanil group,additionally,0.2 μg/kg sulfentanil was given intravenously. Patients in oxycodone group received intravenous infusion of oxycodone 0.08 mg/kg instead.The changes of HR,MAP and SpO 2 were monitored during medication and intubation.The Ramsay scores before intubation, the PET CO 2 and comfort degree after intubation were recorded. Results There were no statistically significant differences in hemodynamic changes,Ramsay scores and comfort level between the two groups during drug-injection and intubation.SpO 2 of patients in oxycodone group was higher than that of sulfentanil group after injection of drugs,but PET CO 2 of oxycodone group after endotracheal intubation was lower.Conclusion The combination of oxycodone and dexmedetomidine can be safely used in awake tracheal intubation,for it shows effective sedation and analgesia,less respiratory depression and other side-effects compared with sufentanil.
