Objective To investigate the role of acid and bile reflux in children with gastroesophageal reflux disease (GERD) and to evaluate the significance of detecting acid and bile reflux in diagnosing GERD in children.Methods Using ambulatory 24 h pH mo-(nitoring) and bilirubin monitoring technique, we simultaneously assessed the changes of intraesophageal pH and bile reflux in 23 subjects (including 11 healthy controls and 12 patients with GERD).Results The time of esophageal acid exposure (pH

OBJECTIVETo determine whether oral statins can delay the progression of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).

METHODSWe conducted a retrospective cohort study of 50-69-year-old males who came for physical examination in our hospital between January 2003 and December 2008. We designed the inclusion criteria, followed them up for 5 years, and investigated the relationship of oral statins with the clinical progression of BPH and LUTS.

RESULTSTotally, 653 men met the inclusion criteria and were included in this study, of whom 283 were treated with oral statins (group 1) while the other 370 with none (group 2). There were no statistically significant differences between the two groups in age and baseline IPSS, Qmax, and prostate volume (PV) (P > 0.05). During the follow-up, 24 cases in group 1 and 35 cases in group 2 were excluded for obvious dys-uria. A gradual increase was observed in IPSS in both groups 1 and 2 year by year from the baseline to the 5th year of follow-up, but significantly lower in the former group (4.27 +/- 1.16, 4.63 +/- 1.05, 5.27 +/- 0.96, 6.41 +/- 1.04, 7.21 +/- 1.21, and 7.93 +/-1.50) than in the latter (4.24 +/- 1.35, 5.26 +/- 1.23, 6.84 +/- 1.20, 8.75 +/- 1.84, 10.82 +/- 3.01, and 12.98 +/- 4.21) (P < 0.01); a gradual decrease was seen in Qmax, though markedly higher in group 1 ([26.56 +/- 2.09], [24.06 +/- 1.94], [21.33 +/- 1.66], [19.24 +/- 1.54], [17.44 +/- 1.53], and [16.27 +/- 1.37] ml/s) than in group 2 ([26.74 +/- 2.40], [23.62 +/- 2.01], [20.63 +/- 1.69], [17.72 +/- 1.48], [14.82 +/- 1.11], and [11.86 +/- 1.24] ml/s) (P < 0.01); and a gradual increase was found in PV, but remarkably smaller in the former group ([19.82 +/- 4.94], [22.60 +/- 4.99], [25.80 +/- 5.20], [27.92 +/- 5.05], [29.11 +/- 5.24], and [29.97 +/- 5.26] ml) than in the latter ([20.21 +/- 4.78], [24.30 +/- 4.98], [28.50 +/- 5.14], [32.84 +/- 4.77], [36.99 +/- 4.78], and [40.90 +/- 4.78] ml) (P < 0.01). Longer medication of statins was associated with better efficacy.

CONCLUSIONOral statins can significantly delay the clinical progression of BPH and LUTS.

OBJECTIVETo investigate the effects of simvastatin on the proliferation and apoptosis of prostatic epithelial RWPE-1 cells.

METHODSRWPE-1 cells cultured in vitro were treated with simvastatin at 0, 10, 20, and 40 μmol/L for 24, 48, and 72 hours followed by determination of their proliferation by MTT assay, and their apoptosis by flow cytometry. The mRNA and protein expressions of Bcl-2, Bax, and Cx43 were detected by fluorescence quantitative RT-PCR and Western blot, respectively.

RESULTSAfter 72 hours of treatment with simvastatin at 10, 20, and 40 μmol/L, the inhibition rates of the RWPE-1 cells were (21.07 ± 6.41)%, (34.87 ± 9.65)%, and (47.18 ± 10.88)%, respectively, significantly higher than (1.21 ± 0.54)% in the control group (P < 0.05) and in a dose-dependent manner (P < 0.05); the cell apoptosis rates were (0.066 ± 0.016)%, (0.126 ± 0.023)%, and (0.192 ± 0.025)%, respectively, remarkably higher than (0.015 ± 0.005)% in the control (P < 0.05) and also in a dose-dependent manner (P < 0.05); the mRNA and protein expressions of Bcl-2 were decreasing while those of Bax and Cx43 increasing with the increased concentration of simvastatin (P < 0.05). The expression of Cx43 was correlated negatively with that of Bcl-2 but positively with that of Bax.

CONCLUSIONSimvastatin inhibits the proliferation of prostate epithelial cells and induce their apoptosis by acting on the gap junctional intercellular communication.

Objective To investigate the characteristic and clinical significance of airway inflammation in children with acute asth-ma. Methods Underwent sputum induction and sputum induction in children (n=34) with acute asthma was repented in recovered children ( n = 24).Induced sputum were also taken from 15 healthy children as controls.Total and differential cell counts were per-formed. Interleukin(IL)-8、IL-6 were measured,The relationship between inflammatory cells and IL-8、 IL-6、peak expiratory (PEF) were analyzed.Results The inflammatory cell infiltrate was mixed including eosmophilic granulocytes, neutrophils, and macrophages. They decreased significantly, but eosinophilic granulocyte remained a higher percentage compared with healthy subjects. There was low-er percentage of lymphocytes at acute exacerhation.Eosinophilic granulocytes were correlated with the degree of airflow obstruction. Levels of IL-8、IL-6 were elevated during the acute exacerbation and decreased at resolution.IL-8 was correlated significantly with neutrophils at acute exacerhation and resolution.IL-6 was correlated signifficantly with eosinophilic granulocytes at acute exacerbation. Conclusions Airway inflammation is chataeterized by infiltration of eosinophils, neutrophils and macrophages.IL-8、IL-6 possibly is the important cytokines of airway inflammation in children with acute asthma. Increased eosinophils in induced sputum correlates with asthma severity. Therapy to the cytokines may have potential values.J Appl Clin pediatr,2004,19(12): 1023-1025

The cholinergic anti-inflammatory pathway (CAP) is a neurophysiological mechanism that regulates the immune system. The CAP inhibits inflammation by suppressing cytokine synthesis via release of acetylcholine in organs of the reticuloendothelial system, including the lungs, spleen, liver, kidneys and gastrointestinal tract. Acetylcholine can interact with alpha7 nicotinic acetylcholine receptors (alpha7 nAchR) expressed by macrophages and other cytokine producing cells, down-regulate pro-inflammatory cytokine synthesis and prevent tissue damage. Herein is a review of the neurophysiological mechanism in which the CAP regulates inflammatory response, as well as its potential interventional strategy for inflammatory diseases.

The NF-kappaB pathway regulates the expression of over 150 target genes, e.g., cytokines, chemokines, leukocyte adhesion molecules and inducible effector enzymes. Consequently, it plays a crucial role in innate and adaptive immune responses, inflammatory response, stress responses, apoptosis and so on. IkappaB kinase (IKK) is the key of this pathway, and it owns a special structure which consists of catalytic subunit and regulatory subunit. Naturally, the activation of IKK needs the interaction of the two subunits and phosphorylation by its upstream kinases. Actually, there are two methods of activation of the NF-kappaB pathway, and both of the methods need the IKK complex. Given to the crucial role of IKK, researchers have isolated and synthesized amounts of IKK inhibitors, and these provide a great convenience to develop novel anti-inflammatory and anti-tumor drugs.

Objective To evaluate the efficacy and feasibility of the coil-and-glue method for the reduction of lung volume in rabbit emphysema model.Methods Sixteen rabbits of emphysema model were divided into the occlusion group(n=10),in which both anterior bronchi were occluded using the coil-and- glue method,and the control group(n=6).The maximal static pressure of airway(P_(max)),peak expiratory flow(PEF),end-expiratory volume(EEV)and pressure of oxygen(PO_2)were measured at ante- emphysema,post-emphysema,1 week and 4 week after occlusion respectively.The expectoration(or migration)of coil and collapse of lung were also investigated.Results P_(max)was(20.0?1.3)and(17.1? 1.4)cm H_2O(1 cm H_2O=0.098 kPa)in the occlusion group at ante-emphysema and post-emphysema respectively.P_(max)was(19.2?1.4)cm H_2O in the occlusion group in the 1 week after the occlusion,while (17.1?1.5)cm H_2O in the control group(F=6.68,P
