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 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 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 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.

Objective To investigate the clinical value of contrast-enhanced ultrasound (CEUS) in the diagnosis of postoperative complications after pancreas transplantation.Methods Eighty-six post pancreastransplantation patients were examined by CEUS to observe the perfusion of contrast agent,plot timeintensity curve (TIC),and compare to the results of enhanced CT,MRI and pathology.Results Eleven cases of thrombosis,13 cases of rejection and 13 cases of pancreatitis were observed among 86 patients.Result from CEUS showed that:① Distribution of normal pancreatic grafts vascular and parenchyma was even,TIC follows positive skewed distribution.②Thrombosis:there was no perfusion in the embolic vessels and no enhancement or low uneven enhancement in the parenchyma.③ Rejection:perfusion of the parenchyma was slow,peak value was decreased,rising and falling slope of the TIC was reduced with blunt peak.④Pancreatitis:perfusion of the parenchyma was uneven,the regional low enhanced area was visible,clear of the contrast agent was relatively slow,rising slope of TIC was reduced and the peak value was decreased.Conclusions CEUS can monitor the perfusion of the pancreatic grafts vascular and parenchyma,and get useful perfusion parameters.It has been proven as an effective method to definitely diagnose postoperative complications after pancreas transplantation.

Objective To investigate the quantitative analysis of tissue diffusion of real-time elastography(RTE) in chronic renal allograft injury(CRAI) and the relationship between RTE and the level of serum creatinine(Cr).Methods Sixty-nine cases of allograft renal transplantation patients were detected by conventional ultrasound and RTE.According to the time after operation and Cr,they were divided into three groups:group A (in three months after operation and normal Cr,25 cases),group B (more than three months after operation and normal Cr,23 cases),and group C (more than three months after operation and high Cr,21 cases).The results were compared and analyzed.Results ①Contrast between group A and group B,there were differences on Cr and average ralative strain value(MEAN),area ratio of low-strain region (％ AREA),complexity (COMP),skewness (SKEW),(P ＜ 0.05).② In group B,there was correlation between Cr and ％AREA,MEAN,SKEW (r =0.682,P ＜0.05; r =0.628,P ＜0.05; r =-0.481,P ＜0.05).③To make ROC curve,MEAN has higher sensitivity (90.9％),COMP has higher specificity and accuracy (68.0％,81.8％).④ To apply the third result in group C,4 or 5 cases in 21 were abnormal.Conclusions There is a good correlation between the quantitative analysis of tissue diffusion and the level of serum creatinine.RTE can indirectly reflect CRAI,and it is a new method of ultrasonic to evaluate renal allograft function.
