【Abstract】 Background The prevalence of Helicobacter pylori(H.pylori)infection is high in China.But the clinical outcomes differ in the infectors,which may be associated with genetic and environmental factors,as well as the genotype of H.pylori.Objective To explore the clinical significance of relationship between types of serum antibodies against H.pylori and gastric diseases.Methods A total of 2 650 patients who underwent gastroscopy and H.pylori serum antibody test in Guangzhou First People's Hospital,Guangzhou Medical University,from January 2009 to December 2017 were enrolled after excluding those with previous H.pylori eradication treatment.Patients were divided into five groups based on gastroscopy and pathological results:chronic non-atrophic gastritis group(1 011 cases),chronic non-atrophic gastritis with erosion group(468 cases),gastric ulcer group(795 cases),chronic atrophic gastritis/dysplasia group(236 cases),and gastric cancer group(140 cases).No H.pylori eradication therapy was performed in the selected patients.Serum H.pylori-specific antibodies CagA,VacA and Ure were detected by protein array.The associations of H.pylori prevalence and H.pylori types with different gastric diseases were compared among five groups.Results The prevalence of H.pylori was 74.58%,74.34%,72.14%,71.58% and 64.49% for chronic atrophic gastritis/dysplasia,gastric ulcer,gastric cancer,chronic non-atrophic gastritis with erosion and chronic non-atrophic gastritis groups,respectively,showing a significant intergroup difference(P<0.05).A total of 1 596 cases of H.pylori typeⅠ strains infection and 259 cases of type Ⅱ strains infection were detected.The prevalence of H.pylori type Ⅰ strains was significantly higher than that of type Ⅱ in all the groups(P<0.05).The prevalence of H.pylori type Ⅰ differed significantly in each group(χ2=22.586,P<0.01).The prevalence of H.pylori type Ⅰ strains in gastric ulcer group was higher than that in chronic non-atrophic gastritis/dysplasia group(P<0.005).Among the 1 596 patients with H.pylori type Ⅰ strains,CagA+VacA antibody accounted for 60.15%(960/1 596),followed by VacA antibody,accounting for 34.27%(547/1 596),and CagA antibody accounted for 5.58%
(89/1 596).The prevalence of CagA+VacA antibody was higher than that of CagA and VacA antibody in each group,the prevalence of VacA antibody was higher than that of CagA antibody(P<0.05).The prevalence of CagA antibody differed significantly in each group(χ2=19.054,P<0.01),and the gastric ulcer group was higher than the chronic non-atrophic gastritis group(P<0.005).The prevalence of VacA antibody differed significantly in each group(χ2=20.204,P<0.01),and the chronic non-atrophic gastritis group was lower than the chronic non-atrophic gastritis with erosion group and gastric ulcer group(P<0.005).The prevalence of Ure antibody differed significantly in each group(χ2=63.967,P<0.01),and the prevalence of Ure antibody in chronic non-atrophic gastritis group was higher than that in gastric ulcer group and chronic atrophic gastritis/dysplasia group and gastric cancer group(P<0.005);chronic non-atrophic gastritis with erosion group was higher than gastric ulcer group,chronic atrophic gastritis/dysplasia group,gastric cancer group(P<0.005).Conclusion H.pylori infection is closely related to gastric lesions.Different types of H.pylori infection have different pathogenicity.Type Ⅰ strains are the main pathogenic strain of gastric diseases,while the co-expression of both CagA and VacA is most prevalent.

【Abstract】 Background After carotid artery stenting(CAS),microembolism occurs not only in the ipsilateral carotid artery blood supply area,but also in the contralateral carotid artery blood supply area and vertebrobasilar artery blood supply area.The risk factors,such as advanced age and carotid plaque ulceration,for microembolization in the carotid artery blood supply area ipsilateral to the stented carotid artery are relatively clear,but those for microembolization in carotid artery blood supply areas contralateral to the stented carotid artery are rarely mentioned in domestic studies.Objective To investigate the occurrence of microembolism in the blood supply area of the contralateral carotid artery after unilateral CAS and analyze its risk factors.Methods 164 consecutive patients with carotid stenosis scheduled to undergo unilateral CAS from December 2013 to August 2018 in Department of Neurology,Weifang People's Hospital were enrolled.General data(sex,age,prevalence rates of hypertension,diabetes,hyperlipidemia,coronary heart disease,atrial fibrillation,and smoking,stroke history,preoperative carotid stenosis degree),postoperative clinical data(degree of carotid stenosis,degree of contralateral carotid stenosis,incidence of contralateral carotid occlusion,left carotid artery lesions,and type Ⅱ/Ⅲ aortic arch,and CAM score≥3),and use of closed-loop stent,and average number of catheters and/or guidewires used more than planned,as well as duration of surgery were collected and recorded.According to the results of MRI plain scan of brain within 3 days after CAS,patients with microembolism in posterior cerebral circulation blood area were excluded,the remaining ones were divided into two groups:ipsilateral group(with microembolization occurring at the ipsilateral side of carotid artery supply area)and contralateral group(with microembolization occurring at the contralateral carotid artery supply area or bilateral sides).Results 163 of the 164 cases completed CAS.Plain MRI scan within 3 days after CAS found that 72 cases(44.2%)were newly microembolized,including 39 with ipsilateral microembolization(ipsilateral group),5 with contralateral microembolization and 13 with bilateral microembolization(contralateral group),and 15 with posterior circulation microembolization.Contralateral group showed higher incidence rate of left carotid artery lesions and higher rate of having CAM score ≥ 3 than ipsilateral group(P<0.05).Multivariate Logistic regression analysis showed that the left carotid artery lesions〔OR=10.015,95%CI(2.728,42.680)〕,and CAM score≥ 3〔OR=9.137,95%CI(2.564,36.271)〕were associated with increased risk of microembolization at the contralateral carotid artery blood supply area after CAS(P<0.05).Conclusion Left carotid artery lesion and CAM score ≥ 3 are influencing factors for microembolization occurring at the contralateral carotid artery blood supply area after CAS,which suggests that complicated routes and severe aortic arch atherosclerosis can lead to significantly increased risk of microembolism in the contralateral carotid artery blood supply area after CAS.

【Abstract】 Background Obstructive sleep apnea-hypopnea syndrome (OSAHS) is one of the common sleep disorders.Previous studies demonstrate that change of sleep structure and decline of cognitive function are more likely to appear in older patients,with reasons incompletely determined yet.Up to now,there are few studies focusing on the relationship of the sleep electroencephalogram (EEG) and sleep structure with OSAHS patients at different ages.Objective To explore the characteristics of sleep EEG of patients with severe OSAHS by age,so as to further provide significant information about brain plasticity change for instructing clinical treatment.Methods In the study,67 patients definitely diagnosed with severe OSAHS from June 2017 to March 2018 in the Sleep Disordered Breathing Diagnosis and Therapy Center,Peking University Shenzhen Hospital were selected and were divided into the younger group (18-40 years old,n=34) and the older group (41-65 years old,n=33) based on the latest national age classification standard.We compared the two groups in the aspects of apnea-hypopnea index (AHI),the lowest SpO2 (LSpO2) during the night,sleep efficiency,the percentage of sleep time during various non-rapid eye movement (NREM) sleep stages (N1,N2 and N3),and the percentage of rapid eye movement (REM) sleep period in the total sleep time,electroencephalograph power density of various waves 〔EEG-δ (0.5-4.0 Hz),EEG-θ(4.1-8.0 Hz),EGG-α(8.1-12.0 Hz) and EGG-β (12.1-30.0 Hz)〕 during NREM period,and analyzed the correlation of electroencephalograph power density during NREM,sleep time in REM period and sleep efficiency with AHI.Results As for the percentage of the sleep time during various stages in the total sleep time,it was higher during N1 and N2 stages in the older group than in the younger group,while was lower in N3 and REM period in the older group than in the younger group (P<0.05).During the stages of N1,N2 and N3,the power densities of EEG-δ of patients in the older group were lower than those of patients in the younger group (P<0.05).The power density of EEG-θ of patients in the older group was lower than that of those in the younger group during N3 stage (P<0.05).During the stages of N2 and N3,the power densities of EEG-α of patients in the older group were lower than those of patients in the younger group (P<0.05).During the stages of N1,N2 and N3,the power densities of EEG-β of patients in the older group were higher than those of patients in the younger group (P<0.05).For the patients in the younger group,the correlation of the power density of EEG-δ,EGG-θ and EEG-α,the sleep time during REM period and the sleep efficiency with AHI was negative (r=-0.338,-0.315,-0.383,-0.483 and-0.501,respectively,P<0.05);the power density of EEG-β during NREM period of younger group patients had no linearity correlation with AHI(P>0.05).For the patients in the older group,the power density of various waves during NREM period,the sleep time during REM period and the sleep efficiency had no linearity correlation with AHI (P>0.05).Conclusion There are significant differences between the EEG performance of the younger and older patients with severe OSAHS.The older patients have longer N1 and N2-stage sleep time with shorter N3 and REM-sleep time;compared to the younger group,the EEG-δ during NREM period,EEG-θ and EEG-αduring N3 stage are found to decrease while EEG-β during NREM period is found to increase.All the EEG changes lead to the reduction of deep sleep time and the increase of shallow sleep time for the older patients with severe OSAHS.Consequently,they are easier to wake when coming across external stimuli and intermittent hypoxia,which directly lead to the increase of sleep fragmentation.

【Abstract】 Background Bone marrow mesenchymal stem cells have a strong capacity of immunoregulation and anti-inflammation.Previous research identified that the conditioned medium derived from mesenchymal stem cells (MSC-CM) can downregulate various inflammatory responses and protect the small intestine.However,the effects and mechanisms of the MSC-CM in necrotizing enterocolitis(NEC) inflammation remain unknown.Objective To investigate the role of MSC-CM with inflammatory pre-activation,in regulating NEC inflammatory response in an experimental newborn rat model of NEC.Methods This study was carried out between July 2018 and April 2019.Eighty newborn SD rats(SPF grade) were randomly and equally divided into control group,NEC injury group,NEC injury+MSC-CMNOR group and NEC injury+MSC-CMTNF-α+IL-1β+NO group.DMEM-F12 medium,MSC-CMNOR and MSC-CMTNF-α+IL-1β+NO were given by intraperitoneal injection for the following 3 days to the NEC injury group,NEC injury+MSC-CMNOR group and NEC injury+MSC-CMTNF-α+IL-1β+NO group,respectively.The gross specimen of small intestine were observed,and the terminal ileum and blood samples were collected on the 4th day of intervention.H&E staining was used to observe the histological changes of the small intestine and determine the pathological scores.Inflammatory cytokines in small intestine tissue and serum samples were detected by ELISA.Results Major changes in small intestine specimens:in the control group,the color of the tissue was ruddy and non-hyperemia with good elasticity,peristalsis,and no intestinal wall pneumatosis or necrosis.In both NEC injury and NEC injury+MSC-CMNOR groups,the color of the tissue was dull-red with distinct congestion,pneumatosis intestinalis,necrosis,low elasticity,and dilatation.In contrast,the NEC injury+MSC-CMTNF-α+IL-1β+NO group showed only mild congestion and fair elasticity,without pneumatosis intestinalis or necrosis.Intestinal histopathological score and incidence of NEC:the total intestinal histopathological scores for the control group,NEC injury group,NEC injury+MSC-CMNOR group and NEC injury+MSC-CMTNF-α+IL-1β+NO group were 16,51,43,and 16,respectively,showing a significant difference(H=41.70,P<0.01).The control group showed lower mean intestinal histopathological score compared with NEC injury group and NEC injury+MSC-CMNOR group(P<0.01).And NEC injury+MSC-CMTNF-α+IL-1β+NO group showed lower mean intestinal histopathological score compared with NEC injury group(P<0.01).The incidence of NEC in the control group,NEC injury group,NEC injury+MSC-CMNOR group and NEC injury+MSC
-CMTNF-α+IL-1β+NO group was 0,85.0%(17/20),20.0%(4/20),and 80.0%(16/20),respectively,with a significant difference(χ2=44.00,P<0.01).Mean levels of serum and intestinal pro-inflammatory and anti-inflammatory factors:the mean levels of serum TNF-α,IL-1β,IL-6,IL-8,IL-10 and IL-12 differed significantly across four groups(P<0.01).The mean levels of intestinal TNF-α,IL-1β,IL-6,and IL-10 of four groups were significantly different(P<0.01).Compared with the NEC injury group and NEC injury+MSC-CMNOR group,mean levels of serum TNF-α,IL-1β,IL-6,IL-8 and IL-12 decreased while mean level of serum IL-10 increased significantly in the NEC injury+MSC-CMTNF-α+IL-1β+NO group(P<0.01);mean levels of intestinal TNF-α,IL-1β,IL-6  decreased while  mean level of intestinal IL-10 increased significantly in the NEC injury+MSC-CMTNF-α+IL-1β+NO group(P<0.01).Conclusion The conditioned medium from pre-activated MSCs has protective effects on the intestinal tract of newborn rat model of NEC,which can regulate the balance of inflammatory and anti-inflammatory factors and reduce intestinal damage.

【Abstract】 Background Postoperative pulmonary complication(PPC)is common after esophagectomy,which is closely related with intraoperative one-lung ventilation.PPC not only increases hospitalization expense,but also increases the unplanned readmission rate after discharge.Moreover,it is an independent risk factor for poor prognosis of esphagectomy patients.However,PPC control after esophagectomy remains unsatisfied.Objective To evaluate whether intravenous infusion of lidocaine can produce lung protection effect through the anti-inflammatory mechanism in esophagectomy patients,so as to reduce the possibilities of having lung injury and PPC,and improve patients' prognosis.Methods Sixty adult patients who underwent elective open radical esophagectomy from November 2017 to June 2018 in the Affiliated Hospital of Xuzhou Medical University were selected as the subjects.They were randomly and equally divided into two groups,lidocaine group(group L)and control group(group C).Both groups were treated with the same anesthesia induction and maintenance regimens,the difference was that group L received a loading dose of 2% lidocaine 1.5 mg/kg injected intravenously within 5 minutes at 5 minutes before anesthesia induction(T0),and then infused intravenously at the rate of 1.5 mg·kg-1·h-1 continuously until 1 hour after the end of the operation,while group C received an equal volume of 0.9% normal saline via the same administration procedure.General data were collected.Blood samples were collected at T0,admission to ICU(T1),12h after surgery(T2)and 36 h after surgery(T3),respectively,and oxygenation index(OI),interleukin(IL)-6,WBC,C-reactive protein(CRP),surfactant protein-A(SP-A)were measured.Postoperative indices were also recorded.Results Intervention method and time had interaction effect on OI,IL-6,WBC,CRP and SP-A(P<0.05).Intervention method and time had significant main effects on OI,IL-6,WBC,CRP and SP-A,respectively(P<0.05).At T1,T2 and T3,group L showed higher OI but lower WBC,CRP and SP-A compared with group C(P<0.05).IL-6 in group L was lower than that in group C at T1(P<0.05).In both groups,OI was lower at T1,T2 and T3 than at T0,while IL-6,WBC and CRP were higher than at T0(P<0.05).SP-A was higher at T1,T2 and T3 than at T0 in group C(P<0.05).SP-A was higher at T1 and T2 than at T0 in group L(P<0.05).There were no significant differences in ventilation time in the ICU,ICU length of stay,postoperative length of stay,atelectasis rate,pulmonary infection rate,pleural effusion rate and reintubation rate between the two groups(P>0.05).Group L needed shorter time to have first passage of flatus,first passage of stool,and first oral fluid intake after the surgery than group C(P<0.05).There were no lidocaine-related adverse events,respiratory failure,bronchospasm,aspiration pneumonia and pneumothorax happened in either group.Conclusion Perioperative intravenous infusion of lidocaine may reduce IL-6,WBC,CRP and SP-A,reduce pulmonary inflammatory response,alleviate lung injury and improve patients' OI after esphagectomy,showing certain pulmonary protective effect.

【Abstract】 Background The failure rate of mechanical ventilation weaning is high in elderly patients with sepsis.Although ultrasound has been widely used in the management of critically ill patients in recent years and its evaluation of cardiac and pulmonary function is increasingly used before weaning.However,it is rarely used in the process of weaning in elderly patients with sepsis.Objective To investigate the predictive value of cardiopulmonary ultrasonography parameters on mechanical ventilation weaning results in elderly patients with sepsis.Methods A retrospective case-control study was conducted to analyze the clinical data of 60 elderly patients with sepsis admitted to the intensive care unit(ICU) of Cixi Hospital Affiliated to Wenzhou Medical University from January 2013 to October 2018.Patients' basic information,including gender,age,body mass index(BMI),sequential organ failure score(SOFA),acute physiology and chronic health evaluation systemⅡ(APACHE Ⅱ)score,heart rate(HR) before the spontaneous breathing trial(SBT),and mean arterial pressure(MAP) was collected.Patients' underlying diseases and infection sites were also collected.Common predictors of weaning were recorded,including respiratory rate(RR),maximal inspiratory pressure(MIP),mouth occlusion pressure at 0.1s after onset of inspiratory effort(P0.1),and type B natriuretic peptide value(BNP) after SBT test.The rapid shallow breathing index(RSBI) was calculated.The results of cardiac ultrasonography before spontaneous breathing test(SBT) were recorded.Cardiac ultrasonography parameters included left ventricular septal thickness diamete(IVSTD),left ventricular posterior wall thickness diameter(LVPWTD),left ventricular end diastolic diameter(LVDd),left ventricular end systolic diameter(LVDs),mitral peak velocity of early filling(E),mitral peak velocity of late filling(A),and early diastolic mitral annular velocity(E').E/A,E/E' were calculated.Systolic left atrial area(LAA) was measured.Left ventricular ejection fraction(LVEF) was also calculated.Pulmonary ultrasonography parameters were lung ultrasound scores(LUS).According to the results of the weaning,the patients were divided into the weaning success group and the weaning failure group.The differences of the parameters between the patients in the two groups were compared.The predictive value of the cardiopulmonary ultrasonography parameters in elderly patients with sepsis on results of weaning was evaluated with receiver operating characteristic curve(ROC)curve.Results A total of 60 patients were enrolled,including 35 patients in the weaning success group and 25 patients in the failure group.There were no significant differences in the basic data between the two groups(P>0.05).The incidence of coronary heart disease in the failure group was higher than that in the success group(P<0.05).There was no significant difference in infection sites between the two groups(P>0.05).The RSBI of the weaning failure group was higher than that of the weaning success group(P<0.05).The cardiac ultrasound parameter E' of the success group was higher than that of the failure group,while the E/E' and the LAA was lower in the success group(P<0.05),and the pulmonary ultrasound parameter LUS was also lower in the success group (P<0.05).The results of ROC curve analysis showed that E/E',LUS and LAA had the predictive value for the result of weaning,and the area under curve(AUC) were 0.835,0.751,and 0.680,respectively.When the critical values were E/E'<8.22,LUS<15.50,and LAA<22.85 cm2,the sensitivity were 0.760,0.720,and 0.560,and the specificity were 0.857,0.724,and 0.829,respectively.Conclusion The parameters of cardiopulmonary ultrasound have the predictive value for the outcome of weaning in elderly patients with sepsis,and the predictive value of the successful weaning in elderly patients with sepsis is high when E/E<8.22,and LUS<15.50 before SBT.

【Abstract】 Background The potential hazards of premature atrial contractions(PACs) have been recognized over the years.The ability of clinicians to detect PACs with high frequency and at an earlier stage is particularly important.Ambulatory electrocardiogram(ECG) is the preferred non-invasive examination for such arrhythmias.Although the traditional template-based method(template-based method) has been used for a long time in clinical settings,it cannot meet current clinical needs due to time-consuming.The Lorenz-RR scatter plot with reverse technique(scatter plot method) is a new diagnostic approach that can provide rapid detection and differential diagnosis of PACs.Objective To summarize the characteristics of the Lorenz-RR scatter plot in patients with non-conducted premature atrial contractions(nPACs),and to further improve the diagnostic accuracy regarding PAC
