Objective To investigate the impact of hs-CRP and IVUS on major adverse cardiac event in patients who after coronary artery intermediate lesions stent implantation.Methods 82 patients with clinical diagnosis of coronary heart disease who had a segmental stenosis degree is 40％ ～ 70％ in one major coronary artery on coronary angiography,all of the patients do intravascular ultrasound,patients had minimal lumen area(MLA) of intermediate lesions ≤ 4mm2( the left main coronary artery)or≤ 6mm2( left main coronary artery) who received percutaneous coronary intervention(PCI),and the patients were divided into 2 groups,hs-CRP rise group(≥3mg/L) and hs-CRP normal group(＜3mg/L),compared the rate between the two groups in hospital and follow up periods by typical angina,nonfatal myocardial infarction,cardiac death and target-vessel revascularization and other major adverse cardiac events (MACE).Results The rate on major adverse cardiac event in hs-CRP rise group was significantly higher than the normal group(P ＜0.01 );the restenosis rate in hs-CRP rise group higher than hs-CRP normal group(P ＜0.01 ).Conclusion hs-CRP could predict the rate on major adverse cardiac event in patients with after coronary artery intermediate lesions stent implantation,the patients of hs-CRP rise group should strengthen antiplatelet,anti-inflammatory treatment etc.

Objective To quantitatively evaluate the left ventricular systolic synchrony in patients with chronic renal failure (CRF) by real-time three-dimensional echocardiography (RT-3DE). Methods Thirty patients with CRF and twenty-five normal subjects were enrolled in this study.The M-mode ejection fraction (M-EF), left ventricular end diastolic internal diameter (LVIDd), interventricular septum diameter (IVSd), left ventricular posterior wall diameter (LVPWd) were obtained on two-dimension. The global and regional volume-time curves were obtained on three -dimensional. The end diastolic volume (LVEDV),end systolic volume (LVESV) and ejection fraction (LVEF) of left ventricule, the time to minimal systolic volume (Tmsv) of 16,12,6-segmental standard deviation (Tmsv16, 12, 6-SD), maximal difference (Tmsv16, 12, 6-Dif) were derived from Qlab software . The above parameters as a percentage of the cardiac cycle with different heart rates between patients were also calculated from the Qlab software, which were Tmsv16, 12, 6-SD% and Tmsv16, 12, 6-Dif %, rspectively. Results The indices of HR, LVIDd, IVSd, LVPWd and LVESV were significantly higher while LVEF was significantly lower in the CRF group than those of the control group (P<0.05 or P<0.01); The indices of systolic asynchrony of Tmsv16,12-SD%, Tmsv16,12-Dif, Tmsv16 ,12 ,6-SD/R-R%,Tmsv16,12,6-Dif/R-R% were significantly larger in the CRF group than those of the control group(P<0.05 or P<0.01). Conclusions RT-3DE provides a simple, intuitional and noninvasive approach to assess the systolic synchrony of all the LV segments simultaneously and LVEF in patients with chronic renal failure.

Objective To investigate the alterations of serological endothelin(ET) in patients with kawasaki disease(KD) and its relation with coronary dilatation(CAD).Methods Serological ET were measured in 50 cases of patients with KD in acute phase as well as subacute phase; 30 cases of patients with acute febrile infection(IC) in infective phases and 30 healthy children(HC).Results 1.ET in subacute phase significantly increased than that in acute phase.2.In both acute and subacute phases of KD, ET significantly elevated higher than that in HC; and ET in subacute phase significantly elevated than that of IC. 3. Fifty-four percentage patients with KD were complicated with CAD. For CAD subgroup, ET had no difference with CAD subgroup in subacute phase.Conclusion ET has still increases in subacute of KD,which indicates the relation with coronary artery lesion.

ObjectiveTo observe effect of OT training on patients wearing the upper limd prosthesis. MethodsThe effect of OT to 30 patients with upper arm prosthesis was analyzed using FIM score before and after training. ResultsAfter 1-3-month OT training, the patients' FIM score were improved significantly(P<0.01).Conclusions OT is an effective method on the patients wearing upper arm prosthesis.

ObjectiveTo investigate the rule of changes of the soleus mass and expression of myosin heavy chain (MHC) isoforms mRNA.Methods40 female Wistar rats were divided randomly into the control group and three spinal cord transection (ST) groups, ST7, ST15, and ST30 with 10 animals in each group. Rats in ST groups were subjected to a complete ST between T8 and T10 levels. The right soleus was dissected and weighed at 7, 15, 30 days after ST, and the expression of MHC mRNA isoforms was measured by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe Absolute and relative soleus masses in three ST groups were lower significantly than those of control group (P<0.05). The soleus mass in ST15 and ST30 groups were lower than that of ST7 group (P<0.05). The soleus of control group predominantly expressed MHC-I and some MHC-IIa, whereas the soleus began to express MHC-IIx and MHC-IIb after ST, except for MHC-I and MHC-IIa. ST induced consistently down-regulation of MHC-I mRNA and up-regulation of MHC-IIx and MHC-IIa at three time points after ST. The level of MHC-IIb mRNA expression was very low at three time points after ST.ConclusionST can influence the soleus mass at early stage after ST. ST induces a shift toward a faster muscle phenotype from slow to fast MHC isoform. MHC demonstrates plasticity in response to decrease neuromuscular activation.

Group A,the differences among the three groups were statistically significant(P0.05). TCR,CCR,DAP,OD,BRC in Groups B and C showed trends of increasing,the differences in terms of the contents of BMP-RⅠamong the 3 phases were statistically significant(P0.05);the ER in Group B and C showed a trend of decreasing,thee difference between 4- and 8-week and 4- and 12-week were signifieantly dif- ferent(P0.05).Conclusion After application of glucocorticoid for a short term,pathological changes maintained and showed trends of inereasing in early stage.HBO can reverse these changes.The outcome of 3-course HBO therapy is better than that of 1-course therapy.

ObjectiveTo explore the relations between the alkaline phosphatase(ALP) and the type of cerebral palsy. MethodsThe ALP level of 40 children with different types of cerebral palsy were examined with the Olympus AU-600 apparatus. ResultsThe ALP value of the children with spastic cerebral palsy is normal. The ALP value of the children with athetoid cerebral palsy is higher than spastic cerebral palsy(P<0.001).Conclusions The ALP value can help us to identify the type of cerebral palsy.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.
