Objective To compare the Helicobacter pylori (Hp) eradication rate of different therapies and to explore the effects of Hp eradication on the clinical characteristics of chronic obstructive pulmonary disease (COPD).Methods From December 2006 to December 2009,at China-Japan Union Hospital of Jilin University 89 stable COPD patients with Hp infection were divided into eradication group and non-eradication group.The eradication group was divided into clarithromycin sub group and moxifloxacin sub group.The patients of these three groups all received regular COPD treatment.Esomeprazole,amoxicillin,clarithromycin and colloidal bismuth citrate were used in clarithromycin group.Esomeprazole,amoxicillin,moxifloxacin and colloidal bismuth citrate were used in moxifloxacin sub group.Patients received pulmonary function test,exercise tolerance evaluation,dyspnea scoring and health-related quality of life scoring at recruitment and 12 months after recruitment.The onset frequenly of acute exacerbation of COPD in one year was counted.The data were analyzed by x2 test and t test.Results The Hp eradication rate of clarithromycin sub group (48.4 ％,15/31) was lower than that of moxifloxacin sub group (87.1％,27/31),and the difference was statistically significant (x2 =4.22,P=0.032).There was no significant difference percentage of forced expiratory volume in first second to forced vital capacity in (FEV1％) predicted value between 27 cases in non-eradication group and 53 patients with successful Hp eradication (t=0.677,P=0.265).Of 53 patients with successful Hp eradication,the 6-min walking distance,Borg dyspnea score and saint George's respiratory questionnaire (SGRQ) score were improved significantly (t =1.884,1.877 and 1.773 respectively; P=0.032,0.025 and 0.034 respectively),and there was no improvement in 27 non-eradication patients.There was significant difference in the frequency of COPD acute attack between 53 patients with successful Hp eradication (1.2 times) and non-eradication group (1.9 times) (t=1.812,P =0.034).Conclusions Hp eradication therapy with moxifloxacin in COPD patients reached higher Hp eradication rate.Hp eradication in COPD patients with Hp infection can improve the exercise tolerance of patients,relieve dyspnea,improve quality of life and reduce the frenquency of acute attacks.

In order to investigate the association of genotypes of HLA-DRB1 and HLA-DQB1 alleles with the genetic susceptibility of chronic urticaria (CU), genotypes of HLA-DRB1 and HLA-DQB1 genes were detected by polymerase chain reactions with sequence-specific primers (PCR-SSP) in 42 patients with CU (19 men and 23 women, mean age 30.67+/-12.45 y old as well as 193 racially matched healthy persons in ethnic Han from Hubei provinece. Gene frequencies of HLA-DRB1 * 12, * 0901 (RR=3.11, chi2=7. 579, P=0.006; RR= 2.47, chi2 =5.684, P=0.017) were significantly increased in CU patients as compared with that in healthy people. Gene frequencies of HLA-DQB1 * 05 (RR=0.26, chi2=6.683, P=0.01) were significantly decreased in CU patients. It was suggested that CU was found strongly associated with HLA-DRB1 * 12, * 0901 and HLA-DQB1 * 05, the former might be the genetic markers for susceptibility to CU, but the latter might play a resistive role.

BACKGROUND: Recombinant human granulocyte colony-stimulating factor (rhG-CSF) can mobilize endothelial progenitor cells and enhance new vessels at cerebral ischemia region. OBJECTIVE: To investigate the effects of rhG-CSF on the new microvascular expressions in rat perihematoma after intracerebral hemorrhage. DESIGN, TIME AND SETTING: A randomized control animal experiment was performed at the Central Laboratory of Luzhou Medical College from March to November 2006. MATERIALS: A total of 72 healthy male Sprague Dawley rats and rhG-CSF were used for this study. METHODS: Seventy-two rats were equally and randomly assigned into the sham operation group, the hemorrhage group, the treatment group. According to rat brain stereotaxic atlas, models of intracerebral hemorrhage were made by infusing autoblood from rat tails. Rats in the sham operation group were infused with saline instead of autoblood. Rats in the treatment group were administered rhG-CSF (60 ?g/kg) by intraperitoneal injection at 1 hour after operation. Rats in the sham operation and hemorrhage groups were left intact. MAIN OUTCOME MEASURES: The microvascular expressions of CD34+ in perihematoma were detected at 6, 12, 24, 48 and 72 hours, 7 days; Four rats in each time point. Microvascular production was measured by changes in CD34. The more the CD34 antigens, the more the new vessels were. RESULTS: In the hemorrhage group, the microvascular expressions of CD34+ were significantly higher compared to the sham operation group (P 0.05). Significant differences were measured at 6, 12, 24 and 48 hours (P
