Objective To investigate the optimum threshold value of tracking and triggering technique (surestart) in imaging of coronary artery by 16-slice row CT. Methods 60 patients enrolled in the enhanced scan of coronary artery imaging were divided into 2 groups (group a : heart rate 70 beats/per minute ). The quality of images collected under different threshold value and heart rate was compared. The image quality of coronary artery was ranked by 3 levels, namely, level A, B and C. The data were statistically analyzed. Results The image quality triggered by 160 HU of group b was level A. The image quality triggered by 180 HU of group a was level A. Conclusion The optimum surestart is 180 HU when the heart rate 70 beats/per minute.

Images of 812 patients undergoing dual-source CT coronary angiography were analyzed retrospectively. Effectively nursing can be improved to guarantee the quality of coronary angiography and diagnosis of diseases.

dichloromethane,since the former four components account for more than 90% of the total HRV,which proposed as the target compounds in risk management of the VOCs.

Using Xanthine-Xanthine Oxidase system to generate superoxide ani-on, using H2O2 -Fe2 + system to generate hydroxyl radical, the role of scavenging oxygen free radical by Miltiorrhiza was studied by electron paramagnetic resonance and spin trapping. The result suggested that the scavenging rate of hydroxyl radical by Salvia Miltiorrhiza injection is 65%, and that of superoxide anion is 100%. This result suggests that scavenging cytotoxic oxygen free radicals may be one of important pharmacological mechanism of Salvia Miltiorrhiza.

Gestational hyperlipidemic pancreatitis is an uncommon complication of pregnancy that incurs a high risk of morbidity and mortality of both maternal and fetal patients.We described the response of continous renal replacement therapy in a woman with extreme gestational hyperlipidemia and severe pancreatitis.Five consecutive plasma exchanges didn't lead to a remarkable reduction(10.4% and 4.8%,for the first and fourth times,respectively) at triglyceride levels as the literatures have reported,which reveals that plasma exchange and continous veno-venous heamofiltration may be importment,instead of crucial methods in dealing with gestational hyperlipidemic pancreatitis.Abstract:SUMM ARY Gestational hyperlipidem ic pancreatitis is an uncommon complication of pregnancy that in-curs a high risk ofmorbid ity and mortality of both maternal and fetal patients.W e described the response of continous renal replacement therapy in a woman with extreme gestational hyperlipidem ia and severe pancreatitis.Five consecutive plasma exchanges d idn’t lead to a remarkable reduction(10.4% and 4.8%,for the first and fourth times,respectively) at triglyceride levels as the literatures have reported,which reveals that plasma exchange and continous veno-venous heamofiltration may be importment,in-stead of crucialmethods in dealing with gestational hyperlipidem ic pancreatitis.

Objective: To evaluate the therapeutic effect of combining use of acupuncture and drugs on rheumatoid arthritis(RA) in the early and the active stages of by the imaging of bone and joint with 99m TC-methlene diphosphate(MDP). Methods: 102 cases of RA in the early and the active stages were randomly allocated into the compound Fengshining group (Group A),acupuncture group(Group B), and compound Fengshining plus acupuncture group(Group C).They were treated for 30 days. All patients were examined before treatment and after treatment by 99m TC-MDP imaging of the whole body, hands and feet, and analyzing method of random interested region was used to count the ratio of radioactivity in the affected area of RA to radioactivity in adjacent normal bone(T/TN). Meanwhile, joint swelling index, joint tenderness index, morning stiffness, gripping force, and erythrocyte sedimentation rate (ESR) were also observed. Results: T/TN of the Group A after treatments had no significant difference comparing with that before treatment(t = 1.35, P＞0.05), while the Group B and C had significant differences(t = 5.31, t=8.97, P＜0.01). The changes of clinical and experimental examination in the Group C had more significant differences than those in the Group A and B(P＜0.05).Conclusion: Acupuncture therapy could promote RA recovery, and combining use of acupuncture and compound Fengshining had better effect.

OBJECTIVETo compare the differences in the clinical efficacy on insomnia between shujing massage therapy and medication with estazolam.

METHODSEighty patients of insomnia were randomized into a shujing mass age therapy group (40 cases) and a medication group (40 cases). In the shujing massage therapy group, the spreading massage manipulation was applied along the running course of the gallbladder meridian of foot-shaoyang on the temporal area. The pressing and kneading manipulation was done at Yangbai (GB 14), Benshen (GB 13), Toulinqi (GB 15), Zhengying (GB 17), Chengling (GB 18), Shuaigu (GB 8), and Fengchi (GB 20), etc, 1 min at each acupoint. In the medication group, 1 mg estazolam was taken orally half an hour before sleep. The treatment was given once every day in the two groups. After the continuous treatment for 1 month, every dimensional score and the total score in the Pittsburgh sleep quality index scale (PSQI) and the clinical efficacy were evaluated between the two groups.

RESULTSAfter the intervention, the each item score of PSQI was improved as compared with that before treatment in the patients of the two groups (all P<0. 05). The differences in sleep time and the time for falling into sleep were not significant between the two groups (both P>0. 05). In the shujing massage therapy group, the scores of sleep quality, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score were all lower than those in the medication group (all P<0. 05). The total effective rate was 92. 1% (35/38) in the shujing massage group and was 84. 2% (32/38) in the medication group, indicating the significant difference (P<0. 05).

CONCLUSIONShujing massage therapy achieves the superior efficacy on insomnia compared with the oral administration of estazolam.

BACKGROUND:Separating umbilical cord blood stem cells using tubes has low efficiency,and microbial contamination easily occurs during this process,therefore,safety cannot be ensured in clinical application.lt is urgent to find a method for separating umbilical cord blood stem cells to treat femoral head necrosis.OBJECTIVE:To establish a high efficient,safe,and clinically valuable method to separate umbilical cord blood stem cells.DESIGN,TIME AND SETTING:A self-control experiment was performed at the First Department of Surgery,Zhengzhou Second People's Hospital,Institute of Blood Constituent Application,Henan Red Cross Blood Centre between February 2006 and August 2007.PARTICIPANTS:Eight male patients with femoral head necrosis,averaging 40.6 years of age,were included in this study.Of these patients,4 had the history of hormone application.An average of 90 mL umbilical cord blood was harvested from each healthy normal full term neonate from Maternal and Children Health Care Hospital of Zhengzhou City.The quadruple bags used for separating umbilical cord blood stem cells consisted of 1 main bag,1 empty bag,and 2 physiological saline bags,provided by Shandong Weigao Holding,China.METHODS:Within 6 hours after collection,umbilical cord blood was centrifuged in the empty bag of quadruple bag,which was connected with an aseptic filling machine.After centrifugation,partial blood plasma was discarded,and the remaining erythrocytes were thoroughly mixed by adding hetastarch.Five minutes later,the mixture was diluted with physical saline at 1:1.Umbilical cord blood was slowly added into the main bag (at 1:1),in which,human lymphocyte separating medium was pre-added.After cantrifugation,the upper layer of solution,i.e.,monocyte-rich solution,was transferred into another empty bag.Within 24hours of preservation,after suspension with umbilical blood plasma,umbilical cord monocytes were transfused into patients with femoral head necrosis via superficial vein on the hand back,monocytes≥1×108/portion,2 portions once.There were three treatment courses,each involving three transfusion sessions,one session every 4 days,and a 2-3-month interval between two treatment courses.MAIN OUTCOME MEASURES:Cell recovery rate and cell viability of umbilical cord blood monocytes and improvements in clinical symptoms.RESULTS:The separation of quadruple bags could obtain umbilical cord blood monocytes with high recovery rate.Furthermore,microbial contamination hardly occurred in the process of separation.Hip joint pain relieved or disappeared to different extents in all 8 patients,with an effective rate of 100%.Abduction and internal rotation of hip joint,ambulation distance,and gait were markedly improved.At 6 months after cell transplantation,5 patients presented with changed bone density in femoral head necrosis regions,2 showed normal femoral head morphology,and the remaining 1 exhibited no obvious changes.Joint effusion was reduced or disappeared in 12 hips.Magnetic resonance images showed that femoral head morphology had been improved in various degrees in 9 hips,but no changes in 3 hips.No complications,fever,or allergies occurred during and after cell transplantation.CONCLUSION:The method of separating stem cells from umbilical cord blood in junction with aseptic interface technology is highly effective,safe,and clinically valuable.Multiple intravenous transfusions of umbilical cord blood stem cells provide a novel approach for systemic treatment of femoral head necrosis.

Objective To investigate the influence of thrombus aspiration on ventricular remodeling of patients with ST?segment elevation type of myocardial infarction ( STEMI ) who underwent emergency percutaneous coronary intervention ( PCI) and its predicative value for patients′ prognosis. Methods Three hundred and eight patients who were diagnosed with STEMI line emergency PCI and hospitalized in the Cardiology Department of Jinghai Clinical College of Medical University of Tianjin from March 2011 to March 2014 were retrospective analyzed, including 152 patients received thrombus aspiration during primary PCI as thrombus aspiration group,and the remaining 156 patients without thrombus aspiration as control group. Indexes of myocardial perfusion levels such as ST?segment resolution 2 hours after PCI and TIMI myocardial perfusion grade were measured in all patients. All patients accepted echocardiography examinations to detect left ventricular end diastolic diameter(LVED) and left ventricular ejection fraction(LVEF) 10 days after PCI. The indexes differences of the two groups,secondary end points major cardiac adverse events(MACE) at 6 months were compared. Results There was no statistical difference between the ratio of two groups for ST segment fell more than 50%( 78. 9%( 120/152) vs. 71. 2%( 111/156) ,χ2=0. 428,P=0. 669) . But for ST segment fell more than 70%,the ratio of the thrombus aspiration group was significantly higher than that in the control group ( 73. 7%( 112/152 ) vs. 47. 4% ( 74/156 ) , χ2 = 4. 701, P = 0. 001 ) . Two groups of patients were treated by echocardiography 10 days after PCI,showed the LVED in the thrombus aspiration group was lower than that in the control group((50. 2±4. 7) mm vs. (51. 6±4. 6) mm,t=2. 642,P=0. 008),while the LVEF value was higher than that in the control group((56. 9±4. 9)% vs. (49. 4±4. 2)%,t=14. 434,P=0. 001). Recurrent angina pectoris decreased significantly in the thrombus aspiration group at 6 months ( 4. 61% ( 7/152 ) vs. 10. 90%(17/156),χ2=2. 056,P=0. 040). Conclusion STEMI patients adopt thrombus aspiration that undergoing emergency PCI,not only can improve myocardial reperfusion,especially microcirculation reperfusion, but also can improve the left ventricular systolic function and the prognosis of patients.
