The fundamental principle of the “Traditional Chinese Medicine (TCM) Genome Project” is to carry out genomic studies from the molecular level to discover effective functional genes in medicinal plants which may be cloned and expressed in factories or to transfer into plants for field cultivation Another approach is to carry out research studies to obtain enzymic genes capable of synthesizing bioactive compounds to be replicated in laboratory metabolic engineering processes The subject matter of “TCM Genome Project” and its significance for the modernization of TCM were expounded

Objective To investigate the expression of metabotropic glutamate receptor (mGluR) in murine podocytes.Methods Conditional immortalized podocytes were used in the research.RT-PCR was used to estimate the mRNA expression.Western blotting,immunofluorescence staining and immunoelectron microscopy were employed to determine the protein production.EIA,EMSA and Western blotting were used to examine the cAMP generation and cAMP response element-binding protein (CREB) activation.Intracellular calcium was investigated using confocal microscopy.Results mGluR1 and 5 mRNA and protein were expressed in murine brain and podocytes.In glomeruli,most of mGluR1 expression located in podocytes and was expressed in the submembrane space of the podocytes.Podocytes treated with (S)-3,5-dihydroxyphenylglycine (DHPG,an agonist for mGluR1/5) rapidly generated cAMP and activated CREB.(RS)-1-Aminoindan-1,5-dicarboxylic acid (AIDA,a selective antagonist of mGluR1/5) and SQ22536 (an adenylate cyclase inhibitor),but not 2-aminoethoxydiphenyl borate (2-APB an antagonist of canonical transient receptor potential) blocked DHPG-induced cAMP generation and CREB activation.Following DHPG treatment,intracellular calcium level rose and was prevented by pre-treatment with AIDA and 2-APB.DHPG-induced calcium influx was also prevented by incubation with calcium-free medium.Conclusion Podocytes express functional mGluR1 and mGluR5.

Objective To investigate the incidence, risk factors and outcome of acute kidney injury (AKI) following cardiac surgeries. Methods Clinical data of 1056 patients undergoing open heart surgery in Renji Hospital from January 2004 to June 2007 were retrospectively analyzed. Univariate and multivariate analyses were used to evaluate possible pre-,intra-, and post-operative parameters associated with AKI according to AKI Network (AKIN). Results Of the 1056 patients, 328 (31.06%) developed AKI. In-hospital mortality was 4.07% in all discharges while 11.59% in AKI patients (P<0.01). Multivariate logistic regression analysis revealed that increased age (OR=1.40), pre-operative hyperurieemia (OR=1.97), pre-operative left ventricular insufficiency (OR=2.53), combined surgery (OR=2.79), prolonged operation time (OR=1.43), post-operative circulation volume insufficiency (OR=11.08) were risk factors of AKI. Conclusions AKI is a common complication and associated with increased mortality following cardiac surgery. Increased age, pre-operative hyperuricemia, pre-operative left ventricular insufficiency, combined surgery, prolonged operation time, post-operative circulation volume insufficiency are useful in stratifying risk factors for the development of AKI.

Objective:To explore the difficulties and methods of value-based pricing of healthcare services,and to provide references for the price management of healthcare services in China.Methods:Based on the analysis of literature and policy,the operational methods of value-based pricing are clarified,and the international application experience of value-based pricing is reviewed.Comprehensive field research and interviews are conducted to analyze the difficulties in applying value-based pricing to healthcare services.Results:Currently,there are no mature theories and methods for value-based pricing of healthcare services,and there are also many practical difficulties in financing,payment,assessment and evaluation policies.Conclusion:In the future,it should consider incorporating service experience into the value framework independently of utility,and take"service utility"as the basis for pricing healthcare services,and select relevant indicators for measurement.At the same time,the price of healthcare services should take into account the willingness to pay of multiple parties,and stakeholders need to work closely together to form a consensus on value.

Objective:Compared to pricing based on input value,pricing based on output can better motivate service outcomes towards expectations and enhance input-output efficiency.The path of outcome value-oriented pricing for healthcare services is explored to provide a theoretical foundation for the value-based pricing of healthcare services.Methods:The concepts,methods and international experience of value pricing are sorted out.Results:Outcome-based pricing in healthcare services is divided into effect and utility,and is classified into four categories based on the different emphasis on the effect and utility of healthcare services.Conclusion:Services with a strong emphasis on effectiveness can draw inspiration from the Quantified Quality of Life(QALY)results in the medical technology field,while services with a strong emphasis on utility may require the development of new utility scales for service evaluation.
