Objective To determine the changes of high-sensitive serum C-reactive protein (hs-CRP) in patients with typical chest pain and normal coronary arteriography.Methods One hundred and twenty three patients were included. CRP was determined using a standard technique, and all patients underwent ECG exercise testing. Results Plasma level of hs-CRP was significantly increased in patients with typical chest pain,coronary arteriography negative and exercise test positive.Conclusion Inflammation may play a role in the mechanism of chest pain for patients with normal coronary angiography.

Objective To investigate the influential factors of systemic lupus erythematosus(SLE) activity during pregnancy and their relationship with pregnancy outcome.Methods A retrospective analysis of the clinical history of 66 pregnant women with SLE from 1991 to 2005 was carried out.Results(1) Those patients with unstable status progestation,patients being newly diagnosed with SLE during pregnancy or patients irregularly using prednisone became active during pregnancy.The disease was active in 32 cases(the active group)and inactive in 34 cases(the inactive group).(2)Obstetric complications in the active group included:9 cases of preeclampsia,13 cases of fetal growth restriction(FGR),7 cases of therapeutic abortion and 15 cases of premature labor;and the corresponding numbers in the inactive group were 1,5,1 and 4, respectively.All the numbers were significantly different between the two groups(P

group Nor(P0.05).Conclusions The changes of ambulatory pulse pressure can reflect the degree of EH.The obvious increase of PP and decrease of DBP maybe are the exclusive features of ABPM in EH patients with target organs damage.

Objective To investigate the safety and obtain parameters of microeoagulation of dorsal root entry zone (DREZ) of cervical cord with bipolar foreps on animal model,and provide histological base for clinical application of treatment of brachial plexus avulsiol pain using microcoagulation of dorsal root entry zone.Methods On the base of swine's weight and spinal cord size in similar to human being,it was chosen to be experimental animal.The right DREZs of cervical cord were microcoagulated with bipolar forceps.The swines were fed in normal way.Their activities were observed.The mass change of the cervical cord segment were observed after 3 weeks and the cervical cord segment was fixed with 10% fromalin,paraffin sliced,HE dying.Coagulating space,depth and width were measured under microsope.The coagulating parameter were adjusted according to measuring outcome in order to achieving a most avaliable parameter.Results All post-op swine survived.When the microcogulation were made with bipolar forceps adopted following parame- ters:The distance of between the polar was 2.0 mm;The diameter of polar was 0.3 mm.The inserting depth 2 mm,the coagulated power 18 watt,the coagulated time was 2 second,then the width of lesions of DREZ in cross section was 1.15 mm and the depth of lesions was 3.10 mm,which was consistent with the area of hu- man DREZ of cervical cord.Conclusion The experiment on swine suggested,microcoagulation of DREZ by bipolar forceps is safe and no mortal complications when the testified parameters are adoped,and can achieve the area of DREZ of cervical cord in human.

AIM:To investigate the differences among Lenstar 900, A-scan ultrasound and keratometer in measurement of axial length ( AL ) , anterior chamber depth ( ACD ) and corneal curvature ( K1 , K2 , Km ) , and evaluate the consistency of the instruments, with the purpose providing references for the clinical application of Lenstar 900.
METHODS: In this study we picked up 36 patients ( 50 eyes ) underwent cataract surgery, and lens nucleus hardness were under level IV. Before the operation, AL, ACD and K1 , K2 , Km were measured by Lenstar 900, A-scan ultrasound and keratometer respectively. The differences between the results were compared by the paired t-test. The correlation of the results was analyzed by Pearson correlation analysis, and the consistency was measured by Bland-Ahamn method.
RESULTS: The mean AL and ACD values measured by Lenstar 900 and A-scan ultrasound had no significantly statistic differences (P>0. 05). The K1, K2, Km measured by Lenstar 900 and keratometer were not significantly statistical different (P>0. 05). The results measured by these three instruments had close linearity correlation ( r>0.9, P<0. 01). The consistency of the results was well in Bland-Ahamn analysis.
CONCLUSION:The preoperatively biometric result of Lenstar 900, A - scan ultrasound and keratometer in patients with cataract are all reliable, and they can be substituted by each other. However, Lenstar 900 can not only measure AL, ACD and corneal curvature at the same time, but also cornal thickness, lens thickness, white to white, pupil size, optical axis eccentricity, retinal thickness and so on. It has a number of advantages such as non-touching, convenient and efficient, and can be recommended to use widely.

By analyzing the traditional educational mode and subject of the higher medical education, the basic method and emphasis of the experimental class of the clinical medicine educational innovation have been established, and the general frame of the educational innovation content has been constructed, the executive essential point and point in the content of the educational innovation have been made. After several years of the practice and positive exploration, the class has achieved success.
