OBJECTIVE To evaluate the difference of efficacy of sublingual immunotherapy on different age patients with allergic rhinitis. METHODS 229 patients with dermatophagoides farina drops allergic rhinitis who have finished SLIT at least 2 years were enrolled and analyzed by retrospective analysis. All patients were divided into different age groups: pre-adolescence(n=107), adolescence(n=53), adulthood(n=69). Indexes for therapeutic effects of SLIT visual analogue scale(VAS) score, rhinitis symptom scores, medication scoreintra- and inter groups were assessed during different stage of treatment(3 months, 1 year and 2 years). Data were analyzed with SPSS 19.0 software. RESULTS Compared with prior treatment, after the SLIT for 3 months, 1 year, 2 years, VAS scores, rhinitis symptom scores, medication scoresof all the patients with allergic rhinitis are significantly decreased; Differences of rhinitis symptom scores(H=0.844, 4.153, 2.669, P>0.05), VAS score(H=1.356, 3.720, 0.313, P >0.05), medication scores(H=1.044, 5.841, 3.399, P>0.05) between groups had no statistical significance at different stage after treatment(3 months, 1 year and 2 years); The differences between 2 years and 1 year of SLIT treatment showed statistical significance in the VAS scores(Z=1.635, P =1.635). CONCLUSION SLIT with dust mites drops had good curative effect and security in patients with allergic rhinitis, which hadno obvious difference between different age groups.

Aim To study the effect of ginsenoside F1 on the enzyme activity and expression of gene of CYP3 A4 through activation of pregnane X receptor ( PXR ) . Methods With different concentrations of ginsenoside F1 treated on LS174T cells, the expression of CYP3A4 mRNA was determined by Q-PCR, and the enzyme activity was measured by P450-GloTM CYP3A4 assay according to the manufacturer′s instructions, fur-ther PXR-CYP3 A4 stable translation HepG2 cell lines were used to test ginsenoside F1 activates PXR by re-porter gene screening assay. Results The results re-vealed that the levels of CYP3 A4 gene and protein ex-pression were significantly increased by ginsenoside F1 in a concentration-dependent manner. At the same time, reporter gene screening showed that ginsenoside F1 could also enhance the transcriptional activity of PXR. Conclusion Ginsenoside F1 can significantly up-regulate the gene expression and enzyme activity of CYP3A4 via the PXR-CYP3A4 pathway.

OBJECTIVETo construct a function model that can be used in the diagnosis bladder outlet obstruction (BOO) resulting from benign prostatic hyperplasia, and to develop a diagram allowing the judgement of bladder outlet for patients with different detrusor contractility, especially with impaired one.

METHODSUrodynamic and clinical data of 131 men were analyzed retrospectively. By Logistic analysis, a function model was constructed. Based on the model, a diagram allowing the evaluation of bladder outlet was drawn. The cutoff point for diagnosing BOO with the function model and the curve was confirmed by ROC curve analysis.

RESULTSThe function model (BOOI) was obtained by the formula 5.03 x residual fraction + 0.04 x PdetatQmax - 0.20 x Qmax - 0.91 + alpha (alpha = 0 for those with low pressure-low flow on P-FS, alpha = 1.42 for high pressure-low flow, alpha = -7.30 for high pressure-high flow). The cutoff point for BOOI diagnosing BOO was 0.36. When validated, the sensitivity, specificity, positive predictive value, and negative predictive value were 85.7%, 91.7%, 96.0% and 73.3% respectively.

CONCLUSIONThe BOOI, with an easy calculation mode, could predict the probability of BOO. The sensitivity and specificity of the criterion for the diagnosis of BOO were satisfactory. The curve we drew could help to differentiate the obstructed men with low pressure-low flow and thus benefit them by surgical relief of their obstruction.

OBJECTIVESince 2011 EB-APS conference, we hypotheses that phase switching of inspiration-expiration is dominantly initiated by oscillatory information PaO2, PaCO2 and [H+] via fast peripheral chemical receptors. However, the evidence of the waveform of ABG is lack.

METHODSSix surgery patients with normal heart function and negative Allen test, had been placed the arterial catheterization directly connected to 3 x 1 000 mm pre-heparin plastic pipe for continuous collecting arterial blood. We counted the number of heart beat for the blood collecting time, and separated the blood pipe into the heart beat numbers' short pieces using haemostatic forceps, then put pipe into iced water at once fir analyzing PaO2, PaCO2, pH and SaO2 as soon as possible. We selected two breaths cycles of waveform from each patient for data calculations of magnitudes and time interval.

RESULTSThe heart beat numbers for filling blood into pipe were 16 ± 2, and all covered more than 2 breathing cycles. Each breathing cycle is cover 5 ± 0.6 heart beat. There were significant changes of PaO2, PaCO2, [H+] a and SaO2 (i.e. the highest high values compare to the next lowest values, P < 0.05). The time interval of changing PaO2, PaCO2, [H+]a and SaO2 magnitudes were 11.28 ± 1.13 mmHg, 1.77 ± 0.89 mmHg, 1.14 ± 0.35 nmol/L and 0.52% ± 0.44% respectively.

CONCLUSIONThis simple continuous beat-by-beat arterial blood sampling and ABG analyzing method is new and practicable. We obtain a clear evidence of periodic parameters ABG waveform, which following breathing cycle.

To study the effect of Siwu decoction on the function and expression of P-glycoprotein (P-gp) in Caco-2 cells. The Real-time quantitative poly-merase chain reaction (Q-PCR) was used to analyze the mRNA expression of MDR1 gene in Caco-2 cells. Flow cytometer was used to study the effect of Siwu decoction on the uptake of Rhodamine 123 in Caco-2 cells, in order to evaluate the efflux function of P-gp. Western blotting method was used to detect the effect of Siwu decoction on the P-gp protein expression of Caco-2 cells. Compared with the blank control group, after Caco-2 incubation with Siwu decoction at concentrations of 3.3, 5.0, 10.0 g x L(-1) for 24, 48, 72 h, the mRNA expression of MDR1 was up-regulated, suggesting the effect of Siwu decoction in inducing the expression of MDR1. After the administration with Siwu decoction in Caco-2 cells for 48 h, the uptake of Rhodamine 123 in Caco-2 cells decreased by respectively 16.6%, 22.1% (P < 0.05) and 45.4% (P < 0.01), indicating that the long-term administration of Siwu decoction can enhance the P-gp efflux function of Caco-2 cells. After the incubation of Caco-2 cells with Siwu decoction for 48 h, the P-gp protein expression on Caco-2 cell emebranes, demonstrating the effect of Siwu decoction in inducing the protein expression of P-gp.

OBJECTIVETo investigate the mechanism of influence of phosphoprotein associated with glycosphingolipid microdomains 1 (PAG1) on the biological behavior of human prostatic cancer cell line PC-3M-1E8.

METHODSThe expression of GST-Raf1-RBD recombinant protein, a specific binding domain of active Ras (GTP-Ras), was induced by IPTG in JM109 bacterium. SDS-PAGE and coomassie brilliant blue staining were performed using cleaved product of the bacterium to determine the expression of the fusion protein. GST-pull down essay was designed to detect the level of active Ras in PGA1 and vector transfected, respectively and in the native PC-3M-1E8 cells. Western blotting was used to detect the expression levels of downstream proteins of Ras signal pathway which may be related to the function of PAG1. Phalloidine labeled by tetramethylrhodamine-5-(and-6) isothiocyanate (TRITC) was used for the staining of intracellular F-actin, Laser passing confocal microscopy was adopted for observing change of the cell morphology and the arrangement of F-actin.

RESULTSAfter IPTG induction, the GST-Raf1-RBD recombinant protein, with a molecular weight of 33 000, was noticed to be highly expressed in JM109 bacterium. GST-pull down assay revealed that the expression level of active Ras markedly decreased after PAG1-transfection while the total Ras remained unchanged. The expression of p-ERK and cyclin D1 in the PAG1-transfected cells decreased in accordance with the level of active Ras. However, the expression of p21(WAF1/CIP1) and p-Akt didn't show any variation. Additionally, the structure of F-actin was turbulent and the pseudopodia of cells diminished conspicuously after PAG1-transfection. There was a high expression of PAG1 in normal human prostate tissue, however, the positive rate of PAG1 immuno-staining decreased in cases of prostatic adenocarcinoma, correspondent with increasing of the grading index of cell differentiation established in the Gleason grading system for the diagnosis of prostate adenocarcinoma.

CONCLUSIONSAn over-expression of PAG1 in PC-3M-1E8 cells effectively suppresses the activation of Ras and ERK, as well as the cyclin D1 expression, leading to an inhibition of the proliferation ability of tumor cells. The turbulence of F-actin and reduction of pseudopodia of cells result in an impairment of cell mobility, invasiveness and metastatic capability. In human prostate and prostatic adenocarcinoma tissues, the expression of PAG1 is related to the cellular differentiation and malignancy.

OBJECTIVEWe investigate the magnitudes of waveform changes of arterial blood gas (ABG) in patients with heart failure.

METHODSFive patients with heart failure were selected, continuous collecting radial artery blood and measured PaO2, PaCO2, pHa and Sao2. We selected two typical breaths cycles of waveform changes of ABG from each patient for data analysis. Comparison of the adjacent highest and lowest values to verify the presence of a periodic waveform changes of ABG, and in addition, we used t test to analysis the range of waveform changes of ABG in patients with heart failure and patients with normal cardiac function and compared whether the difference between them.

RESULTSThe 5 patients (2 surgical and 3 ICU) with heart failure, were 4 male and 1 female, (69 ± 7)year, (169 ± 10) cm, (75 ± 19)kg, LVEF = (38 ± 3)%. The heart beat numbers for full blood into the blood sampling pipe were 17 ± 2, and all covered more than 2 breath cycles. There were significant changes of PaO2, PaCO2, [H+]a and SaO2 (P < 0.05). The magnitudes of changing PaO2, PaCO2, [H+]a and Sao2 were (7.94 ± 2.02)mmHg, (1.18 ± 0.56)mmHg, (0.54 ± 0.17)nmol/L and (0.21 ± 0.07)%, and they were (6.1 ± 1.5)%, (3.2 ± 1.5)%, (1.5 ± 0.5)% and (0.2 ± 0.1)% from their mean respectively. Even these magnitudes fo all ABG parameters were trendily lower than those of patients with normal cardiac function, but only PaO2 and [H+]a were significant (P < 0.05).

CONCLUSIONUsing this simple continuous beat-by-beat arterial blood sampling method, we obtained a clear evidence of periodic waveform of ABG parameters following by breath cycle in patients with heart failure, but the magnitude trendily be decreased.
