The development status of regional longitudinal healthcare alliances in China was analyzed in the paper.As found by the authors, such existing problems as the healthcare administrative system and fiscal input system, the crisis of confidence on primary medical institutions, poor information platforms, and limited means of medical insurance payment, constitute roadblocks for healthcare alliances to play their roles.Proposals of the paper cover such grounds as follows: the government to make a top-down design and a longitudinal and integrated healthcare system can be built;to build a corporate structure for the alliances, with greater fiscal support;to reform the medical insurance payment practice for integrating interests of medical associations;to clarify the responsibilities of tertiary hospitals, for building a win-win mechanism among stakeholders, and improving the information sharing platform.These measures, if in place, can propel the healthy development of healthcare alliances in China.

Objective A rabbit model of common carotid artery grafted by external jugular veins was used. Vein grafts were transferred by c-myc antisense oligodeoxynucleotides(ODN) and carried by soluble stent. Try to find a new approach to prevent veins graft failure on molecular basis. Methods New Zealand rabbit were randomly divided into five groups, 10 animals each. Pretreating the soluble stents with synthesized c-myc ODN, following stents: (1) control group; (2) soluble stent; (3) soluble stent with sense-ODN; (4) soluble stent with antisense-ODN; (5) soluble stent with mismatch-ODN were put into the vein graft during end to end anastomosis. After 7, 28 and 90 days of operation, vein grafts were harvested. HE and ET stain were made aim to calculate the extent of intima hyperplasia. The expression of c-myc and PCNA were identified by immunchemistry methods. Situ hybridization and Northern Bloting were made to assess the expression of c-myc mRNA quantitatively and semi-quantitatively in veins. Results In the vein grafts of 7,28,90 days post-operation of soluble stent antisense-ODN group ①Intima hyperplasia were inhibited significantly compare with other four groups. ②The expression of c-myc and PCNA were inhibited significantly compare with other four groups. ③C-myc mRNA expression level was significantly Lower than the other four groups. Conclusion Soluble stent can transfer c-myc ODN effectively. C-myc antisense-ODN transferred by soluble stent can inhibit the expression of c-myc and PCNA, can inhibit intima hyperplasia of vein graft significantly, thus preventing the stenosis of vein graft.

Objective:To assess coronary stenosis using 256-slice spiral CT (CTA).Methods:The data of 126 pa-tients diagnosed as coronary heart disease (CHD)using CTA and coronary angiography (CAG)Were retrospectively analyzed.The CAG results for CHD Were regarded as “gold standard”diagnosing CHD.The CTA diagnostic value for CHD and consistency of CAG and CTA diagnosing coronary stenosis Were analyzed.Results:A total of 393 cor-onary segments Were assessed using CTA.According to CAG results for CHD ,the CTA diagnostic accuracy Was 89.3%,sensitivity Was 91.4%,specificity Was 84.8%,negative predictive value Was 82.2% and positive predictive value Was 92.8%;the consistency of CAG and CTA diagnosing coronary stenosis Was good (Kappa value =0.755, P<0.01).Conclusion:The 256-slice spiral CT can diagnosing coronary stenosis,it possesses high sensitivity in di-agnosing vascular stenosis;as a simple and noninvasive examination it can be used as a reliable method for early screening subhealthy population and reexamine of putients With coronary heart disease.

Objective To discuss the liver function recovery affected by the portal vein flow in patients who underwent adult-to-adult living donor liver transplantation using the right lobe. Methods Seventy-four donors and recipients were included in this study. Intraoperative Doppler ultrasound (IOUS)were performed before splitting the donor liver and 1 hour after the graft reperfusion. The diameter and velocity of portal vein were measured and recorded for calculation of portal vein flow(PVF). Liver function tests were undertaken at the day 2nd,7th, 15th and 30th postoperative,respectively. Results One hour after reperfusion of 74 grafts,the PVF were significantly increased (2. 84 ± 0. 93) fold. Seventy-four grafts were divided into 4 groups according to the different degrees of the increase of PVF. The levels of blood bilirubin total(TBIL) among 4 groups were differently at the day 2nd,7th, 15th and 30th postoperative. High PVF contributed to recipient's prolonged hyperbilirubinemia ( P ＜0. 001 ). The levels of ALT, AST among 4 groups were differently at the day 7th, 15th and 30th postoperative( P ＜0. 001). Conclusions Detection of portal vein hemodynamics in living donor liver transplantation by IOUS may assist surgeon to anticipate the graft's function and take surgical therapies to secure the graft and the recipient.

Objective To study the apoptosis-inducing effect of Oridonin on PC-3 cells line and the role of Survivin in the process.Methods After PC-3 cells were incubated with different concentrations of Oridonin,cell viability was analyzed with MTT assay.The percentage of earlier apoptosis cell was analyzed by flow cytometry.The protein expression of Survivin in PC-3 cells were detected by Western blot and fluorescent quantitative PCR.Results Oridonin effectively inhibited the proliferation of PC-3 cells in a concentration-time dependent way.After PC-3 cells were treated with Oridonin ( 2.5,5,10,20,40 μmol/L)for 48 hours,the cytotoxicity index were 9.2％,25.3％,39.3％,77.2％,92.5％ and the IC50 of PC-3 cells was 10.29 μmol/L,respectively.Flow cytometry was used to detect the effect of different concentration of Oridonin (0,10,20,40 μmol/L) for 48 hours,the apoptotic rates of PC-3 cells were 4.8％,15.4％,19.5％,27.4％ ( P ＜ 0.05).Oridonin down-regulated Survivin protein in a concentration-dependent way in PC-3 cells.Conclusions Oridonin can induce the apoptosis of PC-3 cells by a concentration-dependent manner.Oridonin can induce the apoptosis of PC-3 cells by down-regulated Survivin protein.

This paper develops an intelligent NO delivery system cooperating with the ventilator to make NO inhaled safely, reliably, conveniently and economically, which is based on correlation between the parameter setup of the ventilator and the concentration of NO. The circuit control system consists of a mass flow controller and a CPU mainly. A mixing unit is designed to mix NO with the gas from the ventilator uniformly. Clinical experiments show that the NO from the intelligent delivery system can decrease PH and increase SaO2 with the concentration of generated NO2 less than 5ppm.
