Objective To study the changes of SUR1-regulated NCCa-ATP channels in core area during focal cerebral ischemia and reperfusion in rats, and to explore the therapeutic window of focal cerebral ischemia. Methods Adult male Wistar rats were rendered to undergo 120 minutes of the left middle cerebral artery occlusion (MCAO) by the intraluminal thread technique before reperfusion. The core area of the left hemisphere cortex ischemia/reperfusion at different times (reperfusion:R3 h, 6 h, 8 h, 12 h and 24 h) was taken to be tested the level of mRNA and protein expression of sulfonylurea receptor 1 (SUR1) using RT-PCR and Western-blot techniques. SUR1 of the ischemic brain microvascular endothelial cells were observed by immunofluorescence double staining at the peak expressing time point of SUR1. Results We found the up-regulation of SUR1 mRNA and SUR1 protein in ischemic infarcts tissues for R3 h, 6 h, 8 h and 12 h, peaked at R8 h, compared with the sham-operation group ( <0.05) . However, SUR1 expression increased was observed at R12 h by double immunofluorescence in microvascular endothelium. Conclusion SUR1-regulated NCCa-ATP channel may take part in cerebral ischemic damage during focal cerebral ischemia and reperfusion. The expressions of SUR1 mRNA and SUR1 protein were up-regulated in ischemic infarcts tissues. The data suggested that the best time to apply SUR1 inhibitor is within 8-12 hours after ischemia and reperfusion.

Solid tumor growth and metastasis depends on angiogenesis.Anti-angiogenesis cancer therapy research has become one of the hot topics.Studies have shown that many kinds of Chinese medicine have an effectiveness of anti-tumor angiogenesis. It is one of the most important mechanisms to anti-tumor Chinese medicine.Chinese medicine on the anti-tumor angiogenesis research in recent years will be reviewed.

[Objective]To investigate the effect of transforming growth factor ?1(TGF-?1) genes transfection on the proliferation and differentiation of chondrocyte by adenovirus vector,and to observe the quality in repair cartilage defect through constructing tissue-engineered cartilage.[Method]Using replicat ion defective adenovirus Adeno-X~(TM) as a carrier,Articular chondrocytes were transferred by high titers level recombinant adenovirus taking TGF-?1 genes.Ultromicrostructure,prolife ration anddifferentiation were observed by light and electron microscope,flow cytometry and so on.Induce expression of exogenous genes coding protein and cartilage cell phenotype were detected by Immunocytochemistry and Northern blot.Gross observation,histology and effect classification were used to evaluate results in repair cartilage defect by combi nation of infected chondrocytes and bone matrix gelatin(BMG).[Result]Immunocytochemistric staining showedthe expression of exogenous gene coding proteins after infection,and procollagen Ⅱ mRNA in cells was detected increasingly by Northern blot.TGF-?1 stimulated proliferation of chondrocytes in primary cultured,and resulted in recruitment of articular chondrocytes into S-G2/M phase.Chondrocytes seeded onto BMG showed high level of proliferation.Transplantation in vivo showed: cartilage defect was repaired satisfactorily by Combination of BMG and infected chondrocytes,and the structure of repair tissue got close to normal articular cartilage.[Conclusion] Articular chondrocytes prolifera tion could be stimulated by adenovirus vector taking TGF-?1 genes,which could be used to constructed tissue-engineered cartilage,and applied in repairing joint cartilage defect.

0.05).② On diagnosing ACS,the area under ROC curve of sCD40L was 0.773,the sensitivity,specificity and validity are 82.8%,61.9% and 85.7%,respectively,which were all highest among so much indexes.Conclusion High serum sCD40L levels may suggest vulnerable plaque,and it's somewhat valuable in diagnosing ACS.

Objective To investigate the effect of intrathecal gastrodin on skin cancer pain in mice.Methods Thirty-two female Balb/c mice,aged 8 weeks,weighing 20-25 g,were randomly divided into 4 groups (n=8 each) using a random number table:sham operation group (group S),skin cancer pain group (group SCP),gastrodin group (group G),and artificial cerebrospinal fluid (ACSF) control group (group ASCF).Skin cancer pain was produced by injecting phosphate buffer solution 20 μl containing about 2 ×105 4T1 breast cancer cells into the plantar surface of the left hindpaw.At 14th day after inoculation of cancer cells,ASCF 5 μl was injected intrathecally in S and ACSF groups,and gastrodin 150 μg/kg (5 μl) was injected intrathecally in group G.Before inoculation,at 30 min before intrathecal injection,and at 15,30,60,90,120 and 150 min after intrathecal injection,the thermal paw withdrawal latency (TWL) was measured.The expression of acid-sensing ion channel (ASIC)-3 mRNA in the spinal dorsal horn was detected using the real-time reverse transcriptase polymerase chain reaction after the last measurement of the pain threshold.Results Compared with group S,the TWL was significantly decreased at each time point before and after intrathecal injection in SCP,ACSF and G groups,and the expression of ASIC-3 mRNA in the spinal dorsal horn was significantly down-regulated in group G (P＜0.05).Compared with group SCP,the TWL was significantly increased at each time point after intrathecal injection,and the expression of ASIC-3 mRNA in the spinal dorsal horn was significantly down-regulated in group G (P＜0.05),and no significant change was found in the parameters mentioned above in group ACSF (P＞0.05).Conclusion Intrathecal gastrodin can reduce skin cancer pain and down-regulate ASIC-3 expression in the spinal dorsal horn which is helpful in maintaining the analgesic effect in mice.

In order to help a surgeon to determine a proper canal filing cutting path in a hip replacement operation conveniently, this paper presents a kind of probe with combined structure. Firstly, the doctor can use this kind of combined probe to choose canal filing cutting path. Then, the doctor can use computer to guide the surgeon to file femoral cavity along the selected canal filing cutting path. Through hip replacement corpse experiments, filing effects and used time of using combined probe group and separate control group were analyzed. The experiment results showed that the methods introduced in this paper could lower the difficulty of hip replacement operations, improve the implantation of hip stem prostheses further, and reduce the incidence of surgical complications.

Objective To investigate the effect of persistent ST-segment elevation after successful direct percutanous coronary intervention (PCI) on the late phase of left ventricular (LV) systolic function in acute anterior wall myocardial infarction.Methods Serial electrocardiograms were record before PCI and 1 hour after reperfusion in 72 patients with acute anterior wall myocardial infarction. The reduction of ST-segment elevation after successful PCI more than 50% was defined as ST-segment resolution (ST reduction group). Persistent ST-segment elevation was defined as ≥50% of peak ST elevation (ST elevation group). Echocardiography was performed on 2 to 3 weeks (early phase) and 5 to 6 months(late phase)after PCI to evaluate the LV function and ventricular wall motion abnormality (VWMA). Results Fifty-three patients (74%) had early ST segment elevation resolution and 19 patients (26%) did not. The LV function and VWMA were similar in two groups during early phase. But during the late phase, ST elevation group patients had lower LVEF and higher LVEDVI, LVESVI, VWMA index compared with ST reduction group (P
