Objective To investigate CT features on increased cerebral vascular density and its pathological mechanism in patients with cyanotic congenital heart disease(CCHD).MethodsPreoperative brain CT scan and clinical data in 82 patients suffering from CCHD were analyzed. According to the increased levels of vascular density,patients were divided into 4 groups:normal,mild,moderate and severe.Relationships between the increased levels of vascular density and Hb,RBC,HCT,as well as the degree of cyanosis,were studied.AVONA was carried out to test blood CT value of cerebral sinuses,Hb,RBC and HCT in different groups. Descriptive analysis and linear regression were adopted to study the correlation between blood CT value and Hb concentration.The relationship of increased vascular density todegrees of cyanosis was analysed by Spearman.Results Among 82 patients,12 patients ( 14.6％ ) werefound in the group of normal vascular density and 70 patients ( 85.4％ ) in the increased vascular density group.Among 70 patients with increased vascular density,22 patients (26.8％ ) with (55.4 ± 2.6) HU,(169 ±6)g/L of Hb,(5.8 ±0.3) × 1012/L of RBC and 0.51 ±0.03 of HCT,29 patients (35.4％) with (61.3 ± 2.9) HU,(209 ± 15 ) g/L,(7.1 ± 0.4) × 1012/L,0.66 ± 0.06 and 19 patients ( 23.2％ ) with ( 68.8 ± 4.2) HU,( 242 ± 23 ) g/L,( 8.3 ± 0.9 ) × 1012/L,0.78 ± 0.08 were observed in the mild,moderateand severe group,respectively.There were significant differences in distribution of blood CT value ( HU),Hb,RBC and HCT in different groups ( F =163.263,134.703,120.974,136.541 ;P ＜ 0.01 ).Blood CT value was positively correlated with Hb concentration ( r =0.98,P ＜ 0.01 ). Vascular density was also positively correlated with the degree of cyanosis ( r =0.86,P ＜ 0.01 ). Conclusions Cerebral vascular density of patients suffering from CCHD presented different levels of increases based on CT scan results due to rise of RBC stimulated by anoxia.The increased level of vascular density was positively correlated with blood Hb concentration,and also associated with RBC accunulation caused by abnormal blood circulation.Moreover,it was positively correlated with the degree of cyanosis.

OBJECTIVETo evaluate the effects of treadmill running exercise of different intensity on early repair of full-thickness defects on the patellofemoral articular surface and the changes in the expressions of matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in SD rats.

METHODSTwenty-four male SD rats with full-thickness defects on the patellofemoral articular surface were randomly assigned into sedentary control (SED) group and low-, moderate- and high-intensity running groups (LIR, MIR, and HIR groups, respectively). The running groups were trained on treadmill for 6 consecutive weeks. Blood samples were collected to detect serum MMP-3 and TIMP-1 levels using ELISA before and after the experiment, and the femoral trochlea were collected to assess tissue repair by gross appearance scoring and O Driscoll histological scoring with Safranine O-Fast Green staining and Toluidine blue staining.

RESULTSIn rats in SED group, the defect was filled with hyaline articular cartilage-like tissues, as compared to fibrous tissues in LIR and MIR groups and subchondral bone damage in HIR group. The SED group scored the highest and HIR group the lowest among the 4 groups in gross appearance scoring and O Driscoll histological scoring. No significant differences were found in MMP-3 or TIMP-1 levels among the groups before training (P>0.05), but after 6 weeks of training, serum MMP-3 and TIMP-1 levels differed significantly among the 4 groups (P<0.05), and all the 3 running groups had a significantly higher MMP-3 level than the control group (P<0.05). After the 6-week training, TIMP-1/MMP-3 ratio was significantly higher in SED group than in the 3 running groups, and was the lowest in HIR group.

CONCLUSIONBoth low- and moderate-intensity exercise failed to promote resurfacing of full-thickness cartilage defects on the patellofemoral articular surface in rats, and high-intensity exercise even induces subchondral bone damage. The expression of MMP-3 and TIMP-1 is related to exercise, and the TIMP-1/MMP-3 ratio reflects the extent of tissue repair.
