Objective To compare clinical value of peripheral blood collection and venous blood collection methods in blood tests.Methods 467 patients who received blood test were selected.The venous blood and peripher-al blood were collected,the indicators of blood test were detected,and the test results were analyzed.Results The white blood cell count (WBC),red blood cell count (RBC),platelet count (PLT),red blood cell hematocrit (HCT),hemoglobin (HB)of venous blood were (5.7 ±1.2)×109 /L,(3.72 ±0.48)×109 /L,(218.0 ±57.5)× 109 /L,(41.8 ±19.8)g/L,(115.7 ±13.8)g/L respectively,those of peripheral blood were (6.7 ±3.4)×109 /L, (3.62 ±0.72)×109 /L,(204.0 ±87.7)×109 /L,(32.7 ±20.7)g/L,(103.6 ±19.6),the differences were statis-tically significant (t =5.994,2.497,2.885,6.865,10.908,all P <0.05).The mean red cell hemoglobin concentra-tion (MCHC),mean red cell volume (MCV),mean erythrocyte hemoglobin (MCH)and other indexes had no signifi-cant differences(all P >0.05).Conclusion The test results in patients with venous and peripheral blood was quite different,venous blood test results obtained with greater value in clinical use,it is recommended that routine blood test used venous blood.

Objective To evaluate the role of phosphoinositide 3 kinase/protein kinase B/glycogen synthase kinase 3β (PI3K/Akt/GSK-3β) signaling pathway in mitigation of ischemia-reperfusion (I/R) injury by diazoxide postconditioning in isolated rat hearts.Methods Pathogen-free Sprague-Dawley rats were used in the study.Thirty hearts were excised and passively perfused in a Langendorff apparatus with oxygenated K-H solution at 37 ℃.The hearts were randomly divided into 5 groups (n =6 each) using a random number table:control group (group C),I/R group,diazoxide postconditioning group (group DZ),PI3K inhibitor LY294002 group (group LY),and diazoxide postconditioning + LY294002 group (group DZ + LY).In group C,the hearts were continuously perfused with K-H solution for 70 min.In group I/R,the hearts were perfused with cardioplegic solution 4 ℃ ST-Thomas 10 ml/kg,the perfusion pump was then stopped to induce global ischemia,and 40 min later the hearts were perfused with K-H solution for 30 min.In DZ group,5 min of retrograde perfusion with diazoxide 50μmol/L was performed through the aorta starting from the onset of reperfusion.In LY group,5 min of retrograde perfusion with LY294002 15 μnol/L was performed through the aorta starting from the onset of reperfusion.In LY + DZ group,5 min of retrograde perfusion with LY294002 15 μmol/L was performed through the aorta starting from the onset of reperfusion,followed by 5 min of retrograde perfusion with diazoxide 50 μmol/L.At 20 min of stabilization (T1) and 30 min of reperfusion (T2),heart rate (HR),coronary flow (CF),left ventricular developed pressure (LVDP),left ventricular developed pressure (LVEDP) and ± dp/dtmax were measured.The expression of total Akt (t-Akt) and total GSK-3β (t-GSK-3β) and phosphorylation of Akt and GSK-3β in myocardial tissues were determined by Western blot.Results Compared with C group,HR,LVDP and ± dp/dtmax were significantly decreased,and LVEDP was increased at T2 in the other four groups,CF was decreased in I/R,LY and DZ + LY groups,and the phosphorylation of Akt and GSK-3β in myocardial tissues was increased in DZ group.Compared with I/R group,HR,CF,LVDP and ± dp/dtmax were significantly increased,and LVEDP was decreased at T2,and the phosphorylation of Akt and GSK-3β in myocardial tissues was increased in DZ group,and no significant changes were found in the phosphorylation of Akt and GSK-3 β in LY and DZ + LY groups.Compared with DZ group,HR,CF,LVDP and ± dp/dtmax were significantly decreased,LVEDP was increased,and the phosphorylation of Akt and GSK-3β in myocardial tissues was decreased in LY and DZ + LY groups.Conclusion PI3K/Akt/GSK-3β signaling pathway is involved in the mechanism by which diazoxide postconditioning mitigates I/R injury in isolated rat hearts.

Aim To discuss whether specific mitochon-drial ATP-sensitive potassium channel opener diazoxide ( DZ ) postconditioning activates RISK signaling path-way to protect isolated rat hearts against ischemica reperfusion injury ( IRI ) . Methods Langendorff de-vice was used to establish rat in vitro model of myocar-dial ischemia reperfusion. SD rats were randomly di-vided into normal group ( NOR ) , control group ( CON ) , diazoxide after treatment group ( DZ ) , and LY294002 antagonistic nitrogen Triazine group ( DZ +LY) , with 8 cases in each. The following was com-pared:①whether heart function of each group changed at the end of equilibration and reperfusion; ② at the end of myocardial perfusion and separation, protein was extracted, and protein kinase B ( PKB / Akt ) , P70S6 kinase (P70S6K), endothelial nitric oxide syn-thase ( eNOS) phosphorylation level of expression were analysed by Western blot. Results ① Indicators of changes in heart function: for DZ group at the end of reperfusion , HR , CF , LVDP , LVEDP , +d p/d tmax and -dp/dtmax were significantly better than those in CON group and DZ + LY group ( P <0.01 ) , but worse than those in NOR group ( P <0.01 ); there was no statistical difference in cardioac function at the end of equilibration. ② For DZ group at the end of reperfu-sion Akt, P70S6K, eNOS phosphorylation level of ex-pression were significantly higher than those in NOR group, CON group, and DZ + LY group (P<0.01). There was no difference in expression level of ERK1/2 phosphorylation ( P >0.05 ) . Conclusion Diazoxide postconditioning through the activation of RISK signa-ling pathway can protect isolated rat hearts against is-chemia reperfusion injury.

Objective:To evaluate the bone alteration subject to remodeling and analyze the esthetic result following immediate implant placement of incisors.Methods:In this study,20 patients (1 3 women,7 men)were involved,who needed implants for incisors of maxilla.The patients received 23 im-mediate implants totally.On the day of surgery and 6 months after the implants were placed,Cone beam CT (CBCT)was taken.The thickness of the alveolar ridge and the vertical change of marginal bone levels onthe mesial and distal aspects of theimplants were measured using the computer software (Planme-caRomexis Viewer 3.6.0.R).The evaluation of esthetic result by labial convexity score (LCS)and pa-pilla index score (PIS)were analyzed pre-operation and one year after the final crown was delivered.The statistics with paired-t test for the measurement data and Willcoxon test for rating data were done by SPSS 20.0.Results:The survival rate in the two-year follow-up was 1 00%.The measuring point 1 (MP1 ), MP2,MP3 and MP4 (0,2,4,6 mm apical to the implant platform,respectively)got significant altera-tions after 6 months of the follow-up.These differences were statistically significant (P<0.05 ).The major alteration happened at MP1 and MP4,which got (-0.89 ±2.06)mm and (-0.75 ±1 .28)mm reduction of the alveolar,respectively.The marginal alveolar ridge resorption was (-0.42 ±1 .24)mm and(-0.91 ±1 .96)mm for Ankylos System and Replace System,respectively,and the difference was not statistical significant .The esthetic results were quite acceptable.Before treatment,1 8 incisors rated 3 for LCS,and 2 incisors rated 4 for LCS;after final restoration,only 5 incisors rated 3 for LCS,and 1 4 incisors rated 2 for LCS.Before treatment,1 5 incisors rated 3 for PIS;after final restoration,1 3 incisors rated 3 for PIS.There was no statistically significant difference for the PIS pre-operation and 1 year after final restoration,while there was statistically significant negative change for LCS.Conclusion:Even fol-lowing the proper surgical technique,the alveolar ridge wall still can’t be maintained after immediate im-plant placed in fresh socket of incisors.The inter-dental papilla could be well maintained,while due to the remodeling of labial bone,labial convexity will inevitably collapse.Therefore immediate implant still has esthetic risk.

Objective To investigate correlation between post-stroke depression (PSD) and multiple factors during onset of acute cerebral infarction. Methods Depression was measured with Hamilton Depression Rating Scales (HAMD) in 58 patients with acute cerebral infarction, and their neurological function were evaluated by neurological function defect (NFD) score. Their immunoglobulin G (IgG) index was calculated and level of nitric oxide (NO) in cerebrospinal fluid (CSF) was measured. Lesion and nature of cerebral infarction in 58 patients with acute stroke were located by CT. All the data were statistically analyzed with student-t test and ? 2 test, as well as linear regression model. Results Seventeen of 58 patients of stroke appeared PSD with an occurrence rate of 29.3%. Occurrence rate of PSD was significantly higher in patients with cerebral infarction than in those with cerebral hemorrhage  2=4.86, P
