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.

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.

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.

AIM: To elucidate the effect of ginsenoside Rb1 (Gs-Rb1) on the glucose metabolism to improve the viability of the cardiomyocytes under hypoxia, and whether hypoxia-inducible factor 1α(HIF-1α) and/or AMPKαare involved in the process.METHODS: The neonatal rat cardiomyocytes were cultured, and randomly divided into control group, hypoxia (1% O2 , 94% N2 and 5% CO2 ) group, Gs-Rb1 (200 μmol/L) group, Ara-A (500 μmol/L) group, Gs-Rb1 +Ara-A group, YC-1 (5 μmol/L) group, Gs-Rb1 +YC-1 group, Ara-A +YC-1 group and Gs-Rb1 +YC-1 +Ara-A group.After the intervention for 8 h, the cell viability was analyzed by MTT assay.The protein levels of AMPK, HIF-1αand glucose transporter-4 (GLUT-4) were determined by Western blot.The activities of heterophosphatase (HK), phos-phofructokinase (PFK) and lactic dehydrogenase (LDH) were measured by ELISA.RESULTS: Gs-Rb1 significantly im-proved the viability of hypoxic cardiomyocytes, which was significantly inhibited by YC-1 and Ara-A.In addition, YC-1 and Ara-A had a synergistic effect.Gs-Rb1 increased the protein levels of AMPK and HIF-1αin the hypoxic cardiomyo-cytes, which was significantly inhibited by Ara-A and YC-1.Gs-Rb1 significantly increased the expression of GLUT-4 on the cytomembrane of hypoxic cardiomyocytes, which was significantly inhibited by YC-1 or Ara-A, especially Ara-A +YC-1.Gs-Rb1 significantly increased the activities of HK, PFK and LDH, all those were significantly inhibited by YC-1 or Ara-A.Besides, YC-1 and Ara-A had a synergistic effect.CONCLUSION: Gs-Rb1 improves the viability of hypoxic car-diomyocytes, which may be related to the regulation of glucose uptake and enhancement of glycolysis by synergy of both
HIF-1αand AMPK.

Objective To evaluate the low-dose dual-source whole-body CT angiography in assessing the arteries of Takayasu’s arteritis (TA).Methods Low-dose whole-body CT angiography(CTA)was performed in 57 consecutive patients with suspected TA. The scanning parameters were performed with tube voltage 80 kV and attenuation-based tube current modulation with a referenced tube current at 300 mAs.The volume CT dose index (CTDIvol)and dose-length product (DLP)were obtained for all scans.Subjec-tive and objective image quality of different arteries were assessed in seven anatomic territories,including intracranial,cervical,tho-racic,abdominal,upper extremity,thigh and shank.In addition,CT findings of whole-body arteries were recorded.Results Forty out of fifty-seven patients with definite diagnosis of TA enrolled in this study.Mean CTDIvol and DLP for all patients were (2.5± 0.9)mGy and (403.7±91.4)mGy·cm,respectively.The scoring order of subjective and objective iamge quality was neck,chest, abdomen,thigh,upper extremity,head and shank.5.9% of intracranial arteries,3.3% of lower extremity arteries and 0.5% of upper extremity arteries were extra detected.Conclusion The extra CT findings of intracranial,lower extremity and upper extremity arter-ies provides a more comprehensive evaluation of whole-body arteries involvement.

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.
