OBJECTIVE:To explore the rational structure of hospital drug charge in state hospitals and the approaches to improve the reimbursement mechanism for state hospitals.METHODS:The detailed document about"reforming or cancelling the drug price addition policy in state hospitals"stated in the Proposals on Deepening Reform of Medical System were analyzed. RESULTS & CONCLUSIONS:"Reforming or cancelling the drug price addition policy in state hospitals"does not necessarily mean the simply cancelling of drug price addition policy in state hospitals,instead,it was achieved by establishing reasonable structure of hospital drug charge and improving the reimbursement mechanism for state hospitals guaranteed by complete operational approaches and supporting policy.

OBJECTIVE:To study the preparation method of ranolazine sustained release tablets and to optimize the preparation technology conditions for these preparations. METHODS: The preparation technology conditions were optimized by orthogonal design with the amounts of HPMCP, MC, PH101 and the hardness of ranolazine sustained release tablets as indexes. The optimized results were verified and the in vitro release of ranolazine sustained release tablets was determined. RESULTS: The optimum preparation technology conditions of ranolazine sustained release tablets were as follows: the amounts of HPMCP, MC, PH101 and the hardness were 150mg, 75mg, 30mg, and 10kg, respectively; and the in vitro release rates at 2, 6, and 12h were (29.33?1.05)%, (59.9?1.53)% and (95.60?1.31)%, respectively. CONCLUSION: The delayed release effect of ranolazine sustained release tablets coincided with the predictive value on the whole, and the preparation technology was reproducible. The in vitro accumulated drug release was in conformity with the requirements.

OBJECTIVE:To promote the implementation of drug“zero profit”,and ensure the interests of both doctor and pa-tient. METHODS:Through introducing the related information of drug management and compensation mechanism of drug“zero profit”,the advices were put forward for the heavy financial burden,shortage of hospital income and medical accessibility,etc. RESULTS&CONCLUSIONS:Drug“zero profit”could promote the reform of public hospital. If both doctor and patient could ob-tain benefits,it is very important to strictly enforce compensation mechanism and increase the government investment. Meanwhile, medical service price should be appropriately adjusted to reflect technical value,knowledge value and risk value of medical staff;preparyment of the total amount should be propeled by project,disease,head and other payment methods to control unreasonable medical expenses growth;mechanical of the hospital operating service should be improved to consciously reduce the dependence on drug profits.

To explore an appropriate treatment for patients with upper ureteral stone (＞ 15 mm in size) by comparing the therapeutic outcomes for those undergoing retroperitoneoscopic ureterolithotomy (RPUL) and percutaneous nephrolithotomy (PCNL).A total of 62 patients with large upper ureteral stone were divided randomly into 2 groups.RPUL was performed in group A (n =30) and PCNL in group B (n =32).No significant inter-group difference existed in age,gender,stone location and size,operative duration or surgical success rate (P ＞ 0.05).Blood loss volume,rate of postoperative analgesic usage,time of hospital stay and incidence of postoperative complications in group A were significantly lower than those of group B (P ＜ 0.05).Thus RPUL offers more advantages and better efficacies.

Objective To investigate the effect and hematopoietic reconstitution as well as survival of diffierent kinds of allogeneic hematopoietic stem cell transplantation(allo-HSCT)in the treatment of leukemia.Methods allo-HSCT was used to treat 20 cases of leukemia from March 2003 to July 2006 in my hospital.Twelve of them received allo-PBSCT from HLA matched sibling donors.Four of them received HLA-mismatched unrelated umbilical cord blood transplantation.Three of them received allo-PBSCT from unrelated donors.One of them received bone marrow transplantion from unrelated donors.Results Totally 19 recipients acheived hematopoietic reconstitution.The median time of hematopoietic reconstitution after UCBT was longer than that of HLA matched sibling PBSCT.Seven patients received aGVHD after allo-HSCT,and 4 among them were Ⅰ~Ⅱ degree and 3 cases Ⅲ~Ⅳ degree.Two patients died of relapse,and 3 patients died of GVHD.One patient was puzzled by cGVHD.The others are disease-free survival now.The median time of survival is 30(1~41)months.Conclusion allo-HSCT is effective for the cure of patients with leukemia.UCBT with enough cells and 1~2 mismatched loci is safe and effective for the patients who have no HLA matched sibling donors.

A review of cell traction forces (CTFs) measurement based on Biological MiCro Electromechanical Systems (BioMEMS) microposts matrix is presented.CTFs are exerted by cells and ansmitted to the underly-ing substrate through focal adhesions and close contacts.which is essential for cells movement.Cells probe the mechanicaI compliance of the exlracellular mabix (ECM) in part by locally deforming it with nanonewton-scale traction forces.Precision measurement of CTFs is significant for many researches such as call biology and tissue engineering and so on.Enabled by the advancement in BioMEMS technology,surface treated high aspeect ratio Polydimethyisiloxane(PDMS)micropos matrix devices,which serve as BioMEMS sensom for de-tecting cellular nanoforces and studying in vitro cell mechanics,have been developed.Closely spaced vartical microposts matrixes were designed to encourage cells to attach and spread across multiple microposts,and to bend the microposts like vertical cantilevers as the cells locomote on the surface.Using this dense and dis-crete matrix of microposts rather than a convanfional continuous substrate,CTFs can be directly measured and quantified by processing the microscopy images of the deformations of microposts.The resolution of the force was in tens of nN/μm scale.At first,the conventional CTFs measurement methods were concisely summa-rized.Then BioMEMS microposts matrix method was described in detail,including principle and fabfication process,Surface treatment and cell expedment results.Furthermore,high aspect ratio structure collapse prob-lem was investigated.
