Objective: To investigate the mRNA expression of chemokine receptors in human villi and trophoblasts of first trimester gestation . Methods: The authors first obtained villous tissues from fifteen women who had undergone selective termination at 5 - 10 weeks of normal gestation. Total RNA was then extracted, using the TRIzol reagent, from villous tissues or Percoll-gradient purified trophoblasts. Consequently, the expressions of chemokine receptors in villous tissues and trophoblasts were investigated by way of semi-quantitative reverse transcriptase-polymerase chain reaction.Results: The chemokine receptors, CXCR4 and CXCR6, were highly expressed in each villous tissue, while the CCR6, CCR7, XCR1 and CX3CR1 were moderately expressed in villi. The chemokine receptors, CCR1- CCR5, CCR8 - CCR10, CXCR1 -CXCR3, were expressed only in some villous samples, while no CXCR5 mRNA was found in any villous tissue. The authors also found that the freshly isolated and Percoll-purified trophoblasts expressed CCR1, CCR3 - CCR5, CCR8 - CCR9, CXCR1 - CXCR4, CXCR6, XCR1 and CX3CR1 mRNA. Conclusion: A variety of chemokine receptors were expressed in villous tissues and trophoblasts of human first trimester gestation, hence, these receptors may play an important biological role at the materno-fetal interface in normal human pregnancy.

Sodium houttuyfonate (SH) is a derivative of effective component of a Chinese material medica, Houttuynia cordata, which is applied in anti-infection of microorganism. But, the antimicrobial mechanisms of SH still remain unclear. Here, we firstly discovered that SH effectively inhibits the three types of virulence related motility of.Pseudomonas aeruginosa, i.e., swimming, twitching and swarming. The plate assay results showed that the inhibitory action of SH against swimming and twitching in 24 h and swarming in 48 h is dose-dependent; and bacteria nearly lost all of the motile activities under the concentration of 1 x minimum inhibitory concentration (MIC) (512 mg x L(-1) same as azithromycin positive group (1 x MIC, 16 mg x L(-1)). Furthermore, we found that the expression of structural gene flgB and pilG is down-regulated by SH, which implies that inhibitory mechanism of SH against motility of P. aeruginosa may be due to the inhibition of flagella and pili bioformation of P. aeruginosa by SR Therefore, our presented results firstly demonstrate that SH effectively inhibits the motility activities of P. aeruginosa, and suggest that SH could be a promising antipseudomonas agents in clinic.

OBJECTIVETo observe the efficacy of Chinese herbs for supplementing qi and activating blood circulation (CHSQABC) on patients with acute coronary syndrome (ACS) and type 2 diabetes mellitus (DM) after successful percutaneous coronary intervention (PCI).
METHODSIn this ChiCTR-TRC-00000021, a total of 281 ACS patients complicated with type 2 DM after successful PCI were randomly assigned to the Western medicine treatment group (the control group, treated by routine Western medicine treatment) and the combined treatment group (the treatment group, treated by CHSQABC + routine Western medicine treatment). Patients in the combined treatment group took Xinyue Capsule (2 pills each time, 3 times per day) and Compound Chuanxiong Capsule (2 pills each time, 3 times per day for half a year and 1-year follow-ups). Primary endpoints covered incidence of death, nonfatal myocardial infarction (MI), ischemia-driven revascularization, and secondary endpoints included stroke, heart failure, and rehospitalization for ACS. At the same time scores for blood stasis syndrome (BSS) and the incidence of angina pectoris were evaluated before treatment, at month 1, 3, 6, 9, and 12 after treatment.
RESULTSThe incidence of ischemia-driven revascularization was obviously less in the treatment group than in the control group (P < 0.05). No patient had nonfatal MI in the treatment group, while 5 patients in the control group had it. The incidence of non-fatal MI showed an obvious lowering tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). Four patients readmitted to hospital in the treatment group, while 12 patients readmitted. There existed obvious tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). The incidence of angina was significantly lower in the treatment group at month 6, 9, and 12 than that at month 1 , but it was lower in the control group at 9 months (P < 0.05). The incidence of angina was 15. 4% in the treatment group, obviously lower than that in the control group (26.2%, P < 0.05). Compared with before treatment, scores for BSS were obviously lowered in the treatment group at 1, 3, 6, 9, and 12 months of treatment and in the control group at 3, 6, 9, and 12 months of treatment (P < 0.05). It was obviously lower in the treatment group than in the control group at 3, 6, 9, and 12 months of treatment (P < 0.01).
CONCLUSIONAdministration of CHSQABC combined routine Western medicine treatment could reduce the event of revascularization and post-PCI recurrent angina, and improve scores for BSS of ACS patients complicated with DM after PCI.

Objective To investigate the effects of fosinopril sodium pre-treatment combined with ischemic postconditioning on rat serum and myocardial oxidative stress and proinflammatory cytokines post ischemia/reperfusion. Methods Sixty Sprague-Dawley rats were randomly divided into sham group ( n = 15 ) , ischemia/reperfusion group ( 30 minutes in situ occlusion of the left anterior descending artery followed by 1 hour nitrotetrazolium blue chloride staining, SOD content was examined by colorimetric method, MDA content was detected using thiobarbituric acid method, serum levels of Interleukin-1α (IL-lα), Interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-α) were examined by radioimmunoassay, IL-lα, IL-6 and TNF-α levels of myocardial tissue were detected by ELISA. Results Compared with I/R group, myocardial enzymes and infarction size were significantly decreased ( P < 0. 05, P < 0.01) , serum SOD content was increased and MDA content was decreased (allP<0.01), serum and myocaidial levels of IL-1α, IL-6 and TNF-α were significantly reduced (P<0. 05,P<0.05, P<0.01) in IPoC group. Compared with IPoC group, fosinopril sodium pretreatment further reduced infarction size and myocardial enzyme CK-MB ( P < 0.05 ) , increased SOD content ( P < 0. 05 ) while reduced serum IL-6 and myocaidial tissue TNF-a (P <0. 05, P <0.01). Conclusion Pretreatment with fosinopril sodium enhanced the protective effect of IPoC on rat myocardium underwent I/R injury, possibly by reducing oxidative stress and early inflammatory reaction.

Genotypic and environmental variation in Cd, Cr, As, Ni and Pb concentrations of grains, and the relationships between these heavy metals and Fe, Zn were investigated using 9 rice genotypes grown in 6 locations for two successive years. Significant genotypic variation was detected in the five heavy metal concentrations in grains, indicating the possibility to reduce the concentration of these heavy metals in grains through breeding approach. The environmental effect varied with metal, with Pb and Ni having greater variation than the other three metals. There was significant genotype-environment (location) interaction of the concentrations of all five heavy metals in grains, suggesting the importance of cultivar choice in producing rice with low heavy metal concentrations in grains for a given location. Correlation analysis showed that Cd and As, Cr and Ni, and As and Pb concentrations in rice grains were closely associated, and that Ni concentration in grains was negatively correlated with Zn concentration.

The purpose of establishing an evidence-based clinical pathway is to standardize the clinical practice, improve the quality of health care and cure patients' illness. Since the core of evidence-based medicine (EBM) lies in implementing the current best available evidence of clinical research to direct the decision making in clinical practice, evidence obtained from research should be kept to either in formulating a clinical practice guideline or establishing a clinical pathway. The EBM method for establishing clinical pathway was introduced in this paper, including setting up a compilation team, raising clinical relevant problems, searching and critically appraising available evidence, and incorporating them into the process of clinical pathway establishment, expecting to provide methodological guidance for establishing TCM clinical pathway in future.
