Objective To investigate the relationship between Helicobacter pylori (Hp) infection and carotid atherosclerosis (CAS) progression in patients with high risk of stroke,and to provide clinical evidence for the primary prevention of stroke.Methods Three hundred and thirty-two patients with high risk of stroke were screened from 2 800 people who were consecutively selected and had health examination from June to December 2014 in the Department of Medical Center,General Hospital of Wanbei Coal and Electricity Group.Their clinical information was collected.A total of 267 patients whose carotid ultrasound examinations showed plaques and stenosis were selected for the study.Two hundred and three of the 267 patients who met the screening conditions and completed the follow-up were selected as study subjects.The Hp infection status was detected by the 14C urea breath test and the dynamic progression of CAS was observed.The risk factors of CAS progression were also analyzed.Results Hp infection was found in 170 of 332 patients with high risk of stroke.Among the 267 patients who prompted plaques and stenosis in carotid ultrasound in 2014,203 patients were followed up for 1 year,and 133 patients (65.5％,133/203) were found infected by Hp.Forty-six patients had suggestive carotid stenosis and stenosis aggravating in 2015,31 (67.4％,31/46) of which were found infected by Hp.Logistic regression analysis showed that smoking (OR =1.632,95％ CI 1.275-1.940,P =0.011),systolic blood pressure (OR =1.343,95％ CI 1.105-1.632,P =0.019),low density lipoprotein (OR =1.590,95％ CI 1.188-2.005,P =0.005),oxidative low density lipoprotein (OR =1.732,95％ CI 1.325-2.170,P =0.000) and Hp infection (OR =1.672,95％ CI 1.180-2.154,P =0.016) were independent risk factors for carotid atheroslerosis progression.Conclusions Hp infection was found closely related to CAS progression in patients at high risk of stroke.Positive and effective prevention of Hp infection,advocating smoking cessation and controlling blood pressure and blood fat can effectively reduce the incidence of stroke.

Objectives To observe the effect of continuous positive airway pressure (CPAP)for the treatment of patients with acute cerebral infarction combined with obstructive sleep apnea syndrome (OSAS)and to investigate the influence of CPAP therapy on the recovery of neurological function in patients. Methods From April 2014 to September 2015,68 consecutive patients with acute cerebral infarction combined with OSAS admitted to the Department of Neurology,General Hospital of Wanbei Coal and Electricity Group were enrolled retrospectively. According to whether received the CPAP therapy,they were divided into an observation group (n = 31)and a control group (n = 37). The control group was treated with conventional therapy,and on the basis of the treatment plan of the control group,the observation group was also treated with CPAP therapy. They were all the patients with cerebral infarction who were treated for 14 d. The oxygen desaturation index (ODI),lowest oxygen saturation (LS a O2 ),oxidized low-density lipoprotein (ox-LDL),and superoxide dismutase (SOD)concentration,National Institute of Health Stroke Scale (NIHSS)scores and Barthel index (BI)scores,and the modified Rankin scale (mRS)scores after 3 months before and after the therapy in the patients of both groups were documented. The total effective rate was assessed. Results (1)The ODI and LS a O2 in the observation group and the control group after treatment were better than those before treatment. There were significant differences between the 2 groups (ODI:16 ± 6% vs. 35 ± 21%,26 ± 15% vs. 36 ± 21 %;LS a O2:88 ± 6% vs. 75 ± 11%,80 ± 8% vs. 75 ± 11%;all P < 0. 05). (2)After treatment,ox-LDL of the observation group was lower than that of the control group. There was significant differences between the 2 groups (ox-LDL:487 ± 90 μg/ L vs. 548 ± 77 μg/ L,SOD:111 ± 10 kU/ L vs. 94 ± 15 kU/ L,all P < 0. 01). (3)After treatment,the NIHSS and BI scores of the observation group and the control group were better than those before treatment. There were significant differences (the NHISS scores:5. 2 ± 2. 2 vs. 12. 9 ± 3. 9;7. 6 ± 3. 1 vs. 12. 5 ± 4. 2;the BI scores:88 ± 10 vs. 52 ± 30;81 ± 4 vs. 58 ± 30;all P < 0. 01). The NIHSS and BI scores of observation group were better than those of the control group. There were significant differences (all P < 0. 01). They were followed up for 3 months,the mRS score (1. 3 ± 0. 4)of the observation group was lower than that of the control group (2. 0 ± 1. 1). There was significant difference between the 2 groups (t = 3. 362,P <0. 01). (4)The total effective rate of the observation group and control group was 74. 2% (23 / 31)and 48. 6% (18 / 37)respectively. There was significant difference between the 2 groups (χ2 = 4. 598,P <0. 05). Conclusion The CPAP therapy can alleviate the oxidative stress levels in patients with acute cerebral infarction combined with OSAS in short term and improve the neurological function of patients.
