Objective: To analyze the relationship between high-sensitivity C-reactive protein (hs-CRP) and P wave dispersion (Pd) in patients with lone atrial ifbrillation (AF), and to explore the effect of inlfammation on atrial electrophysiological remodeling.
Methods: Our research included 2 groups. AF group, containing 71 consecutive paroxysmal lone AF patients, and Control group, containing 71 paroxysmal supra ventricular tachycardia patients with the matched age and gender. The clinical characteristics, electrocardiographic Pd assessment and plasma hs-CRP levels were compared between 2 groups. The relationship between hs-CRP and Pd was studied by linear and multi linear regression analysis.
Results: Compared with Control group, AF group showed increased left atrial diameter, Pd and hs-CRP, all P<0.05. multilinear regression analysis indicated that hs-CRP was positively related to Pd in both groups, P<0.01. Multiple logistic regression analysis revealed that hs-CRP was an independent risk factor for AF occurrence (HR=15.430, 95%CI 6.031-39.476, P<0.001), with adjusted Pd, multiple logistic regression analysis presented that both Pd and hs-CRP were the independent risk factors for AF occurrence, both P<0.001, while the HR for hs-CRP predicting AF occurrence was attenuated from 15.430 to 6.246.
Conclusion: Plasma hs-CRP level and electrocardiographic Pd were the important risk factors for paroxysmal lone AF, the interaction between hs-CRP and AF occurrence could be mediated by Pd, suggesting that inlfammation might be involved in atrial electrophysiological remodeling.

Traditional Chinese medicine (TCM) usually views polycystic ovary syndrome (PCOS) as a menstrual disease or infertility disease. Reproductive dysfunction in PCOS is characterized by ovarian androgen excess and disturbance of follicular development, and its main clinical manifestations include delayed menstruation, scant menstruation, amenorrhea or infertility. Insulin resistance is a key pathological mechanism of PCOS. "Tiangui" (kidney essence) as a sex-stimulating essence in female in TCM theory, is essential to the menstruation and pregnancy of women. The disturbance of Tiangui (including time, status and rhythm) would result in female reproductive problems. Current studies of Tiangui indicate that ovary is the target organ of PCOS treatment, and its functional characteristics are consistent with the properties of Tiangui in time frame, state form and rhythm cycle. It is then concluded that ovarian dysfunction in PCOS can be expressed as disorder of Tiangui.

BACKGROUND: Previous studies have confirmed that atrial natriuretic peptide (ANP) exists in different regions of rat gastric mucosa in different densities, and ANP can inhibit the spontaneous contraction of gastric smooth muscles in rat, guinea pig and human.OBJECTIVE: To investigate the ultrastructural localization of ANP-synthesizing cells and the correlation between ANP-synthesizing cells and microvessel density in rat gastric mucosa.DESIGN: Single sampling study.SETTING: Affiliated Hospital of Chengde Medical College. MATERIALS: Eighteen adult male Wistar rats of clean grade, weighing 300-350 g, were used in this study.METHODS: This study was conducted in the Laboratory of Chinese Materia Medica Immunology, Chengde Medical College from October 2004 to July 2007. The ultrastructural localization of ANP-synthesizing cells in rat gastric mucosa was performed by postembedding immunoelectron microscopy technique. The area density of ANP-synthesizing cell distribution was calculated by histochemical technique (saffron solution and toluidine solution staining included). Microvessels of rat gastric mucosa were revealed distinctively by tannic acid-ferric chloride staining method and scanning electron microscope technique.MAIN OUTCOME MEASURES:①The ultrastructural localization of ANP-synthesizing cells in rat gastric mucosa.②The distribution characteristics of gastric microvessels in different regions of rat gastric mucosa.③The distribution characteristics of ANP-synthesizing cells in rat gastric mucosa.④Correlation between ANP-synthesizing cell distribution and microvessel density.RESULTS: ① Ultrastructural localization of ANP-synthesizing cells: It was confirmed that ANP-cells were the enterochrochromaffin (EC) cells. ② Observation of microvessels: The microvessels were stained successfully by tannic acid-ferric chloride and scanning electron microscope technology. Microvessels of gastric mucous were in wriggled way and cut in different cross-sections. They could be clearly observed in distinct three-dimensions. The microvessel density was the largest in the basal glands of rat gastric mucous. ③ Distribution of ANP-synthesizing cells: It was identified that EC cell was only a chromaffin cell in the rat gastric mucosa. The chromaffin granules (brown granules) were localized in the cytoplasm of EC cells. Negative staining for chromaffin granules was detected in the submucosa and smooth muscle. EC cells had different distribution densities in different regions. The density order of EC cells was gastric cardiac region ＞ gastric pyloric region ＞ gastric fundic region in mucosal layer. ④ Correlation between ANP-synthesizing cells and microvessel density: Correlation analysis showed that there was a positive correlation between ANP-synthesizing cells and microvessel density in the gastric cardiac region(r = 0.53, P ＜ 0.05, n=18), and there was a negative correlation between above-mentioned two indices in the gastric pyloric region(r = 0.38, P ＞ 0.05 , n=18)and in the gastric fundic region(r = -0.29, P ＞ 0.05, n=18).CONCLUSION: ANP-synthesizing cells are the EC cells of gastric mucosa. There is a positive correlation between ANP-synthesizing cells and microvessels in the rat gastric cardiac region, while there is a negative correlation between ANP-synthesizing cells and microvessels in the rat gastric pyloric region and in the gastric fundic region.

Objective To investigate the biological effects of insulin resistance(IR)on the porcine granulosa cells which iS induced by wortmannin,the PI-3K inhibitor and mediated by key molecules including GLUT4 and MAPK during insulin signaling.Methods The model of IR porcine granulosa cell was established in in vitro culture by treatment of wortmannin,and was assessed the amount of3H glucose uptake as well as medium glucose levels by glucose oxidase method.The protein and mRNA expression of GLUT4 and MAPK were evaluated by immunofluorescence and RT-PCR respectively.Resuits The glucose intake was decreased by 40% with treatment of wortmannin at 1.5 μmol/L(P＜0.05).GLUT4 and MAPK were localized mainly to cytoplasm of grantdose cells.When granulosa cells were insulin resistant,the expression of GLUT4 was down-regulated whereas MAPK was up-regulated as compared with the controls.Conclusions Wortmannin treatment can lcad to decreased expression of GLUT4 and increase of IR granulose cells.This metabolic phenotype could induce increased expression of MAPK and mitogenic potential,indicating the cross-talk between two pathways of insulin signaling within ovarian cells.

Objective To determine the effect of cheA gene of Helicobacter pylori in the bacterial chemotaxis in vitro and colonization in vivo. Methods The entire cheA and cheY genes were amplified and cloned from genomic DNA of H. pylori NCTC11637 strain. Subsequently, the prokaryotic expression systems of cheA and cheY genes were generated and the target recombinant proteins rCheA and rCheY were extracted by Ni-NTA affinity chromatography. Rabbits were immunized with either rCheA or rCheY for obtaining antisera, and rCheA-IgG and rCheY-IgG in the antisera were prepared using ammonium sulfate precipitation plus DEAE-52 column chromatography. A suicide plasmid of cheA gene was constructed and then a cheA gene knock-out mutant ( cheA - ) was generated based on homologous recombinant exchange using the suicide plasmid. The cheA- mutant was identified using PCR and sequencing. The phosphorylation levels of CheA and CheY molecules of cheA - and wild-type strain were determined by using rCheA-IgG and rCheY-IgG anchoring the target proteins and protein phosphorylation detection kit. The differences of chemotaxis in vitro and colonization in vivo between cheA- mutant and wild-type strain were compared using chemotactic model and BALB/c infection model of H. pylori. Results The cheA gene knock-out in genome of cheA- mutant was confirmed by the results of PCR and sequencing. After treated with 0. 001-0. 1 mol/L HCI for 10 min, the phosphorylation levels of CheA and CheY molecules of wild-type strain were rapidly descended from ( 59.6 ±11.5) μmol and (55.5 ± 10.2) μmol to ( 10.8 ± 2.6) and (5. 5 ± 1.2) μmol (P ＜ 0.05 ), while the phosphorylation of CheY molecule of cheA - mutant was no markedly changed with a persistent lower level ( P ＞0.05). The diameters [(10-20) ± (2-3) mm] of chemotactic aggregative rings of cheA- mutant were significantly less than those [(16-24) ± (2-3)mm] of wild-type strain (P ＜0.05). The positive isolation rate (90%) of H. pylori in gastric biopsy specimens of mice that infected with wild-type strain was remarkably higher than that (40%) of mice that infected with cheA- mutant (P ＜0.05). The result of fluorescence quantitative was also showed that the numbers (6.3 × 103 ±2.1 × 103 copies/mg) of H. pylori in gastric biopsy specimens of wild-type strain infected mice were significantly larger than those (8.3 × 101 ±3. 1 × 101 copies/mg) in gastric biopsy specimens ofcheA- mutant infected mice (P＜0.05). Conclusion The cheA gene of H. pylori has an important role in the bacterial chemotaxis in vitro and colonization in vivo.
