Objective To predict the infarction of related artery(IRA)and the site of occlusion by analyzing the diversify of electrocardiographic ST segment and coronary angiography findings in acute inferior myocardial infarction. Methods Sixty-four patients with acute inferior myocardial infarction were divided into two groups by coronary angiography: right coronary artery(RCA)occlusion group(51 patients)and left circumflex coronary artery(LCX)occlusion group(13 patients). RCA occlusion group included proximal,middle and distal components occlusion, and LCX occlusion group included proximal and distal components occlusion. The cases of STⅢ elevation ＞ ST Ⅱ ,STaVL depression ＞ STⅠ ,STV1 depression,STV7-V9 and STV3R-V5R elevation were recorded and compared. Results The percentage of STⅢ elevation ＞ STⅡ, STaVL depression ＞STⅠ, STV1 no depression, STV7-V9 no elevation and STV3R-V5R elevation was significantly higher in RCA occlusion group than those in LCX occlusion group(P ＜ 0.01 or ＜ 0.05). The percentage of ST Ⅲ elevation ≤ ST Ⅱ, ST,VL depression ≤STⅠ ,STV1 depression,STV7-V9 elevation,STV3R-V5R no elevation was significantly higher in LCX occlusion group than those in RCA occlusion group(P ＜0.01 or ＜0.05). In RCA occlusion group:the sensitivity of STⅢ elevation ＞ STⅡ, STaVL depression ＞ STⅠ and STV1 no depression was 90.2%, 80.4% and 80.4%;the specificity of STⅢ elevation ＞ STⅢ and STaVL depression ＞ STⅠwas 84.6% and 84.6% ;the sensitivity of STV3R-V5R elevation was 51.0%, but its specificity was 100.0%. In LCX occlusion group: the sensitivity of STⅢ elevation ≤ ST Ⅲ and STaVL depression ≤ ST Ⅰ was 84.6% and 84.6%, and their specificity was 90.2% and 80.4%;the specificity of STV1 depression and STV7-V9 elevation was 80.4% and 78.4%; the sensitivity of STV3R-V5R no elevation was 100.0% ,and its specificity was 51.0%. In RCA occlusion group, the percentage of STV3R-V5Relevation was higher in proximal components occlusion than that in distal components occlusion[76.9%(10/13)vs. 27.3%(3/11),P=0.015]. Conclusions The IRA can be initially judged by analysis of the characteristics in the ST segment in Ⅰ,Ⅱ ,Ⅲ ,aVL,V1,V7-V9,V3R-V5R lead in acute inferior myocardial infarction. And the ST segment elevation in V3R-V5R is meaningful in the judgment of proximal and distal components occlusion in RCA.

Objectives To explore the process and regularity of graft after vascularized bone allograft. Methods An adult rabbit model of massive femoral defect was established and reconstmcted with vascularized bone allograft based by laterial rotating femoral vessel.The experiments were carried out in two groups,the experimental group(vascularized bone allograft)and the control group(nonvascularized bone allograft).Then observation on periosteum,cortex and marrow was performed after operation containing in ink-infused specimen. Results The revascularization in the experimental grouD was observed synchronicly on periosteum,cortex and marrow after operation,while the phenomenon of vascularization took place from periosteum to marrow in the control group.The density of micro-vessel in experimental group were 10.0±1.8,15.8±1.5 and 13.8±1.5,13.8±1.5 respectivly after 2,4,8 and 16 weeks.and those were 2.8±0.8,6.0±0.9,5.5±1.0,6.0±1.1 in control group.The ink-infused experiment demonstrated a better revascularization in the experimental group. Conclusion The vaseularization can promote revascularization of graft during bone allograft.

Objective To compare clinical efficacy between the situ secondary spleen pedicle amputation in laparoscopic splenectomy and open splenectomy for traumatic spleen rupture.Methods From January 2013 to June 2015 a total of 70 patients with splenic rupture undergoing splenectomy were devided into laparoscopic surgery (35 cases) and open surgery (35 cases) group.Clinical data included total intraoperative blood loss,the time spent on splenic artery ligation,total operation time,postoperative drainage volume,postoperative hemoglobin,platelet and albumin levels,time of anal exsufflation,hospital stay and postoperative complications.Results The average operation time in the OS group was shorter than that in LS group (P ＜ 0.05).However,LS group was better than the OS group in splenic artery ligation time,postoperative drainage volume,anus aerofluxus time,postoperative platelet count,postoperative albumin recovery,hospital stay and postoperative complications (all P ＜ 0.05).Conclusions The laparoscopic splenectomy by the amputation of in situ secondary spleen pedicle for traumatic spleen rupture has the advantages of a rapid recovery and a low postoperative complication.

OBJECTIVE: To study the influence factors of the oxidation of DHA and EPA,and to find effective antioxidants.METHODS: The oxidation of DHA and EPA was optimized by orthogonal test with the quality of DHA and EPA as indicators and temperature,light and time as factors.The optimized antioxidants were selected by adding salidroside,BHA,BHT,vitamin E into samples.RESULTS: If there is lower temperature,weaker light and shorter storage,the oxidation of DHA and EPA will be more slowly.Effect of salidroside on the oxidation of DHA and EPA is the strongest.CONCLUSION: The oxidation of DHA and EPA can be reduced by lowering temperature,storing in dark place,reducing storage duration and adding salidroside.

Objective To explore the prevalence and influencing factors of obstructive sleep apnoea syndrome(OSAS)among hypertensive patients. Methods Two hundred and ninety-eight hypertensive patients who used a portable OSAS monitoring device were selected as our subjects. Of which,197 patients who completed their OSAS monitoring were divided into OSAS group( 165 cases) and non-OSAS group. Stepwise linear regression and Logistic regression analysis were used to analyze the relevant factors correlated to AHI and OSAS with hypertension. Results The average age of the 197 patients(122 were males)were 59. 93 ± 10. 18 years old. The prevalence of OSAS was 83. 8% in hypertension patients. Body mass index( BMI),systolic pressure (SBP),diastolic pressure(DBP),low density lipoprotein cholesterol(LDL-C)and waist circumference in OSAS groups were(26. 37 ± 2. 77)kg/ m2 ,(159. 59 ± 14. 42)mmHg,(98. 71 ± 9. 40)mmHg,(2. 85 ± 0. 82)mmol/L,(90. 56 ± 8. 62)cm,higher than those in non-OSAS group((22. 43 ± 2. 04)kg/ m2 ,(146. 83 ± 4. 60) mmHg,(85. 51 ± 7. 52)mmHg,(2. 22 ± 0. 60)mmol/ l. ,(81. 84 ± 8. 00)cm). There were statistical differences between the two groups(t = - 7. 654,- 4. 945,- 7. 490,- 4. 110 and - 5. 289;P < 0. 001). BMI,SBP and DBP were positively associated with AHI,and they were in depended risk factors of OSAS(OR(95% CI)=2. 554(1. 408 - 4. 632),1. 432(1. 154 - 1. 777),1. 286(1. 058 - 1. 562);P < 0. 05). Conclusion The prevalence of OSAS is high in hypertension patients. Higher BMI,SBP,DBP are associated with OSAS in hypertension pateints.

Objective To investigate the effect of minocycline on isoflurane-induced hippocampal neuroapoptosis and cognitive dysfunction in aged rats. Methods Forty-five male SD rats were randomly assigned into 3 groups ( n=15): blank control group ( group C) , 1.5% isoflurane group ( group I) and 50 mg??kg-1 minocycline+1.5% isoflurane group ( group M+I) . Minocycline was injected intraperitoneally 12 h before the start of anesthesia for group M+I.Group I and group M+I were exposed to 1.5% isoflurane for 4 h, while group C were exposed to 30% O2-70% N2.At the end of anesthesia, five rats in each group were randomized to analyse arterial blood gas. The other rats in each group were sent back to their home cage until they were fully awake.Fourteen days after anesthesia, Morris water maze was used to assess the cognitive function, and then hippocampi of rats were dissected for detection of the expression of cleaved caspase3, Bax and Bcl-2. Results No difference was found in arterial gas analysis among the 3 groups (P>0.05).Compared with group C, the rats in the group I spent more time locating the platform on the third and fourth training days and the time percentage that the rats in group I spent in the target quadrant was much less (P<0.05).However, these changes were reversed in group M+I (P<0.05).The isoflurane-induced increased level of Bax and cleaved caspase3 and decline of anti-apoptotic factor Bcl-2 were restored by minocycline pretreatment ( P<0.05) . Conclusion Minocycline could attenuate cognitive dysfunction induced by isofluranein aged rats.The mechanism is associated with inhibition of hippocampal neuroapoptosis which is increased by isoflurane.
