Differentiating syndrome factor and forming syndrome type according to symptoms and signs are the rules and processes of syndrome differentiation in traditional Chinese medicine (TCM). TCM syndrome differentiation is a nonlinear complex giant system. In order to solve the key problem of determination of diagnosing weight value for syndrome factor differentiation, a new algorithm of double levels of frequency and weight based on the analysis of frequency statistics was applied, and the accurate syndrome differentiation parameters were acquired. Therefore, based on the nonlinear and multivariate analysis, a new algorithm of calculating diagnostics for syndrome factor differentiation was established.

BACKGROUND: Recently, researchers separate neural stem cells (NSCs) from neural system. As the progenitor of nerve cell and glia cells, NSCs have strong ability of self-renewal and proliferation, and play a very important role in repair process after nerve injury. OBJECTIVE: To review the repairing effect of NSC transplantation on hypoxic-ischemic encephalopathy. RETRIEVAL STRATEGY: Using the "Neural stem cells, brain, hypoxic-ischemic", we searched PubMed database for related articles published in English between 1993 and 2007. 131 articles were collected, and after the first trial, only articles ① related to neural stem cell transplantation for brain injury, and ②published in recently or in authoritative journals were selected. Repetitive researches were excluded. LITERATURE EVALUATION: The articles were about the studies of NSCs and randomized and controlled experiment for hypoxic-ischemic brain injury. Thirty-three English articles were included involving the biological characteristics of NSC, distribution, separation and culture in vitro, and the basic experiment or clinical research about the repair of hypoxic-ischemic brain injury by NSC. Of these articles, there are 7 review articles, and the others were about clinic or basic experiment researches. DATA SYNTHESIS: Researches show that after transplantation NSC can survive in host, furthermore, it proliferates and differentiates to repair the configuration and function of injured brain area. Even though we have achieved much in NSC transplantation for brain injury, yet there are many problems to be resolved, such as NSC source and conservation, the control mechanism of differentiation and proliferation when NSC is cultured in vitro. In addition, the amount or functional activity of NSCs acquired is lower, and the molecular biological features of cells in repaired tissue are uncertain. CONCLUSION: As a kind of ideal seed cell, NSC provides an approach for the repair of hypoxic-ischemic brain injury, and starts a new era of clinic therapy by stem cells.

Syndrome factors as refined diagnostic units are the base of syndrome differentiation,each syndrome factor has the relative symptom and sign.By way of epidemiology and documents investigation,as well as algorithm of double levels of frequency and weight,the symptom and sign for the syndrome factor of Qi-deficiency,Blood-deficiency,Yin-deficiency and Yang-deficiency respectively were extracted correctly,and the weight values of symptoms and signs to syndrome factors were established.

The concept of syndrome in traditional Chinese medicine (TCM) is a nonlinear, open and complicated huge system. Syndrome differentiation in TCM belongs to cognitive and noetic science. To establish a new syndrome differentiation system based on the key elements of the syndrome is necessary for TCM practitioners to promote differentiation ability and reach consensus on differentiation method. With combination of experience and computation models, the Bayesian network was used in the study of the relationship between the key elements of syndrome and the symptoms, and the relationship among different key elements, in which the computing diagnosis result was identical to the result from an experienced TCM doctor. The study showed that Bayesian network is a good method to deal with the information of symptoms and signs for syndrome differentiation, but it is also not to reflect comprehensively the thinking ability of TCM doctors in doing syndrome differentiation.

Objective: To investigate the influence of the closed re-infusion of intestinal juice and EN on the treatment of intestinal fistula.Methods: The study group was composed of 21 patients of intestinal fistula from October 2004 to December 2006.The fistulae was in the 50 cm of the proximate jejunum and caused by trauma and operatin.The leak amount of intestinal juice was more than 1 000 mL.The protein level in serum and the absorption rates of the glucose,fat and nitrogen after the reinfusion of the intestinal juice were measured.Resutls: The protein level in serum and the absorption rates of the glusose,fat and nitrogen was increased after the re-infusion of the intestinal juice.Conclusion: The absorption of the glucose,fat and nitrogen in EN and the protein level in serum can be increased after the closed re-infusion of the intestinal juice.

OBJECTIVE To explore the positive rate of intercellular adhesion (ica) operon and its production- polysaccharide intercellular adhesion(PIA) and the relationship between the rate and adhesion of Staphylococcus epidermidis. METHODS Amplifying icaA of ica operon by PCR and then detecting it by agarose electrophoresis, detecting PIA by Congo red agar (CRA) to detect its adhesive ability by infusion set. RESULTS The icaA positive rate of S.epidermidis was 51.5%; the PIA positive rate was 50%; there was significant difference between the clone numbers of PIA positives and negatives (P

Objective To investigate the effect of Rumo Shengji San on promoting tissue regeneration of skin defect after repair with tissue-engineered skin.Methods The dermal scaffolds were reconstructed by collagen sponge in which human skin fibroblasts were transplanted inside and human keratocytes were transplanted on the surface.The tissue-engineered skin was transplanted into the wound surface of defected skin in naked mice.Rumo Shengji San was applied externally once every other day after transplantation for 2 days.The animals were randomly divided into two groups:external application group and control group,4 mice in each group.The differentiation tissue of the tissue-engineered skin was sampled 9 days after transplantation.The epidermis thickness and dermal capillary proliferation in wound of defected skin were observed with HE staining,and double-labeled immunofluorescence method was used to test dermal laminin(Ln) and typeⅠcollagen protein expression.Results Rumo Sheng Jji San promoted the development of epidermis after transplantation for 9 days.The number of capillaries in dermis was increased,and the expression of Ln and typeⅠcollagen protein was promoted in external application group than that in the control group.Conclusion Rumo Shengji San can promote tissue regeneration of skin defect after repair with tissue-engineered skin.

OBJECTIVE:To develop a method for the determination of tirofiban in Tirofiban hydrochloride/sodium chloride injection.METHODS:Tirofiban was determined by UV spectrophotometry at a wavelength of 225 nm.RESULTS:The linear range of tirofiban was 30～70 ?g?mL-1(r=0.999 7) and its average recovery was 100.04% (RSD=0.23%).CONCLUSION:The method is simple,accurate and reliable for content determination of Tirofiban hydrochloride/sodium chloride injection.

OBJECTIVE:To determine the resistance of clinically isolated bacteria to meropenem METHODS:The resistance of 150 clinically isolated strains to meropenem and several other antibiotics was detected by K-B method and the drug resistant spectra to E coli were compared between meropenem and imipenem RESULTS:The sensitivity of 130 clinical isolates to meropenem was 100% No cross resistant strains of E coli was found to meropenem and imipenem CONCLUSION:Meropenem is highly sensitive to the clinical isolates,and its antibacterial spectrum is similar to that of imipenem
