ObjectiveTo enrich and quantitatively analyze peripheral circulative carcinoma cells by magnetic activated cell sorting (MACS) in colorectal cancer patients.MethodsBlood samples, preoperatively collected from 21 patients with colorectal cancer and 9 healthy volunteers, were labeled by anti-cytokeratin (CK) with magnetic microbeads, and passed through magnetic columns; CK +carcinoma cells were separated from the samples, and quantified by flow cytometry.ResultsCK +CD45 -cells could not be detected from the samples without MACS; in the sample undergoing MACS, the concentrations of CK +CD45 -cells were significantly higher in patient group than in control group(P

OBJECTIVETo evaluate the accuracy of the latest BladderScan BVI9400 on measuring bladder volume.
METHODSTwo bladder phantoms were selected for investigating the accuracy of BVI9400. 341 patients with the iU22 ultrasound examinations were followed by BVI 9400. The difference and correlation between BVI9400 and iU22 were contrastively analyzed.
RESULTSThe relative difference between results from BVI9400 and phantom volume was 2.5% and 1.36%. There was a strong correlation for patients between BVI9400 and iU22 (R = 0.96, P < 0.001). The relative difference between BVI9400 and iU22 decreased with the increasing of bladder volume and had no significant difference with patient's gender (P > 0.1).
CONCLUSIONBladderScan BVI9400 had the ability of high accuracy and good stability of measured data. In view of quick and conveniences, BVI9400 could be as auxiliary equipment on pelvic tumor to evaluate whether the bladder volume during fractional radiotherapy was consistency with that during CT positioning.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.

ObjectiveTo investigate the role of overexpressed proinflammatory cytokines in the pathogenesis of cerebral palsy (CP).MethodsLevels of tumor necrotic factor-α (TNF-α) and interleukin-6 (IL-6) in serum of 31 CP children, 20 healthy children (as controls), 37 neonates with CP risk factors such as hypoxic-ischemic injury and/or perinatal infection, and 20 healthy neonates (as controls) were measured by enzyme-linked immunosorbent assays (ELISA) retrospectively.ResultsLevels of TNF-α and IL-6 of CP children and neonates with CP risk factors were significantly higher than that of healthy controls (P<0.05). TNF-α level of CP children was significantly higher than that of neonates with CP risk factors (P<0.05), but there was no significant difference in IL-6 level between two groups.ConclusionOverexpressed proinflammatory cytokines play an important role in the pathogenesis of CP and may be an independent risk factor of CP.

OBJECTIVETo investigate the impact of intravenous nutrition on plasma free amino acid spectrum and immune function for patients with sepsis.
METHODSForty severe sepsis patients were divided into two groups: Group B (amino acids + glucose + fat emulsion) and Group A (glucose + fat emulsion), 20 healthy individuals were enrolled as control group. The concentration of free amino acid and immune globulin were determined after 3 days.
RESULTSIn Group A, the levels of valine, leucine, isoleucine, alanine, serine, glutamic acid, histidine, proline and glycine were decreased; while the levels of threonine, cysteine, the ratio of phenylalanine and tyrosine (Phe/Tyr) were higher than those in control group. Meanwhile, peripheral blood IgM, complement C3 and C4 were decreased. In group B, all amino acid levels were improved, but the level of alanine, serine, glutamic acid, histidine and proline still lower than those in control group. Similarly, the levels of IgM, complement C3 and C4 in group B were increased.
CONCLUSIONIntravenous nutrition can support the basal requirement of amino acid and improve the immune function of patients with sepsis.

In order to explore the clinical hypolipidemic features of Daidai flavone extract, the pharmacokinetics features of characteristic active ingredients of Daidai flavone extract in normal and hyperlipemia rats were studied and compared. The study established the quantitative determination method of naringin and neohesperidin in plasma by UPLC-MS. Study compared the pharmacokinetics differences of naringin and noehesperidin in normal and hyperlipemia rats on the basis of establishment of hyperlipemia model. Results indicated that the pharmacokinetics features of characteristic active ingredients of Daidai flavone extract in normal and hyperlipemia rats showed significant differences. The C(max) of naringin and neohesperidin in hyperlipemia rats plasma after oral administration of Daidai flavone extract increased obviously, while t1/2, MRT and AUC0-24 h decreased, compared to normal rats. But t(max) showed no differences to that of normal rats. The results further proved Daidai flavone extract would have better hypolipidemic effect in the hyperlipemia pathological status. And the characteristic active ingredients naringin and noehesperidin were the material base of Daidai flavone extract to express the hypolipidemic effect.

Currently, the herbal prescription therapy for corresponding constitutional diseases is a common constitution regulating method. This method has an obvious effect in treating and regulating constitution-related diseases. However, for people who do not have disease, they prefer to regulate constitution with dietary therapy. In this paper, the researchers came up with a design method of constitution regulating and healthcare foods based on medicinal property combination mode of clinical empirical formulas. With "Yupinfeng San", a common formula for Qi-insufficiency constitution and specific endowment constitution, as the example for constitution regulating and healthcare foods, the researchers proved the effectiveness and rationality of healthcare food schemes in terms of the efficacy of single herb and the modern pharmacological study.
