Objective To evaluate the safety and immunogenicity of SARS-CoV-2 inactivated vaccine(Vero cells)for people aged 60 and above with hypertension and/or diabetes. Methods In Songtao Miao Autonomous County,Guizhou Province,hypertensive and diabetic patients aged 60 and above and healthy people were selected as the research objects. They were divided into hypertension group,diabetes group,combined disease group(suffering from hypertension and diabetes simultaneously)and healthy people control group,and injected intramuscularly with SARS-CoV-2 inactivated vaccine(Vero cells)through the lateral deltoid muscle of upper arm at 0 and 21 d respectively,with a dose of 0. 5 mL each time. Adverse events in ≤ 30 min,0 ～ 7 d and 8 ～ 21 d after immunization were recorded and followed up to 6 months after vaccination. Venous blood samples of 5. 0 mL were collected before vaccination and 28 d after vaccination. The sera were separated,detected for neutralizing antibody levels by cytopathic assay and calculated for the geometric mean titers(GMTs)of neutralizing antibody and antibody seroconversion rate. Blood pressure of patients was measured in fixed time before vaccination and 30 min and 1 ～ 7 d after vaccination in hypertension group and combined disease group respectively;The fasting blood glucose was measured before vaccination and 2 h postprandial blood glucose was measured once on the day of vaccination. The fasting blood glucose and 2 h postprandial blood glucose were measured on 1,3,5 and 7 d after vaccination respectively. Results There was no significant difference in the incidence of solicited adverse events among hypertension group,diabetes group,combined disease group and healthy control group（χ2= 1. 790,P = 0. 617）;There was no significant difference in the incidence of non-solicitation adverse events(P = 0. 412). A total of 5 serious adverse events occurred,all of which were judged to be unrelated to vaccines. No abnormal fluctuation of blood pressure and blood glucose was observed. The lower limits of 95% CI of the rate difference of hypertension,diabetes and combined disease groups were all greater than-10%,and the lower limits of 95% CI of the neutralizing antibody GMT ratio were greater than 0. 67,all of which were not inferior to the healthy control group. Conclusion SARS-CoV-2 inactivated vaccine(Vero cells)has good safety and immunogenicity for people aged 60 and above with hypertension and/or diabetes.

Objective To evaluate the effect of motivational interviewing (MI) on the medication adherence and self-efficacy in patients with ulcerative colitis.Methods Totally 81 patients with ulcerative colitis were randomly divided into the control group(n=40) and the experimental group(n=41).The patients in the control group received routine ulcerative colitis education,while the patients in the experimental group received developed motivational interviewing intervention.The problems existing in treatment course were found out through interview and protocols were made with patients together.Results One and three months after the intervention,the scores of medication adherence in the experimental group were (7.20±0.85) and (6.57±1.02),higher than those of the control group(6.48±0.71) and (5.98±0.85),t=3.868,2.655,both P＜ 0.05.Self-efficacy scored higher in the experimental group than that of the control group,(229.73±14.61) vs.(213.60±13.06),t=5.233,P ＜ 0.01.Conclusions Motivational interviewing is much more effective than routine education on the improvement of medication adherence and self-efficacy in patients with ulcerative colitis.

Objective To describe the factors influencing medication compliance of patients with ulcerative colitis (UC) and provide a reference for health care workers developing effective response plans.Methods In-depth interview was conducted to 10 UC patients and the interview results were analyzed by phenomenology research method.Results There were five factors influence medication compliance of UC patients including drug affect,economic burden,living events,follow-up appointment and stigma.Conclusions The medication compliance of UC patients is mainly related to patients lacking of drugs knowledge,heavy burden on drugs cost and shortage of social support etc.The health education and medication supervision on UC patients should be strengthened and the social health insurance system on UC needed to be improved.

Objective To study the neuropathological characteristics of late-onset Alzheimer' s disease (LOAD) in Chinese people, to ensure correct diagnosis of LOAD.Methods Choosing cerebral cortex of temporal layer of 8 cases of LOAD and 5 cases of age-matched normal control group by autopsy.Histopathologlc diagnosis was established in all these 13 cases.Cerebral cortex were taken from temporal layer in 13-101 hours after death and were fixed with 40 g/L paraformaldehyde, followed by paraffin-embedding and serial sectioning with 6 μm thickness.Brain tissue was analyzed neuropatholically by using immunohistochemical staining for β-amyloid (Aβ) and AT8 on these cases.Positive distribution of temporal layer was observed under light microscope.Results The results of immunohistochemical stainings of Aβ and AT8 were positive in all of LOAD.Aβ immunoreactant located in the cerebral cortex.The diffuse plaques, primitive plaques and burn-out plaques of senile plaques were displayed clearly by immunohistochcmical stainings of Aβ.AT8 immunoreactants showed neurofibrillary tangles, neuropil thread and senile plaques in nerve cell of cerebral cortex in different degree respectively.The positive rate Aβ and AT8 were both 8/8 by semiquantitative analysis in AD group.As the normal aging control group, which was 0 and 1/5 respectively.There was significant difference of the positive rate Aβ and AT8 in two groups(χ2 = 13.000,P=0.001; χ2=9.244,P=0.007).Conclusions Sensitive immunnhistochemical technique was significant to display senile plaques and neurofibrillary tangles.The findings demonstrate that immunohistochemistry staining of Aβ and AT8 can display senile plaques and neurofibrillary tangles clearly.The connection of the 2 different methods might improve diagnose accordance rate of AD.

Objective To evaluate the left ventricular(LV)torsion in patients with permanent pacemaker implantation by speckle tracking imaging(STI).Methods Twenty-two patients with permanent pacemaker implantation were enrolled.Eleven of them had the pacing electrodes placed in the right ventricular(RV)apex(RVA group)and the others had the pacing electrodes placed in the RV outflow tract (RVOT group).Thirteen healthy subjects were studied as controls.The basal and apical shortaxis views of the left ventricle were acquired and analyzed using EchoPAC 7.0 station.Results ①The curves of LV torsion in the pacing groups were generally lower than those in the control group and notched.The torsion parameters of RVA group and RVOT group were all less than those of control group(Ptw:12.57±4.19°vs 12.43±5.46°vs 18.98±5.73°,all P＜0.05),but there were no significant differences between RVA group and RVOT group.The time of torsion was not changed in the pacing groups because there were no significant differences among the three groups.②The values of Ptw-a(peak twist of the apex)were gradually declined among control group,RVA group and RVOT group.There was statistical difference in Ptw-a between RVOT group and control group(7.40±4.27°vs 12.70±6.82°,P=0.0364).③The basal Tp-SD(standard deviation of times to peak twist)of RVOT group was significantly longer than that of control group[14.1(7.97～22.70)%vs 4.87(3.03～7.79)%,P=0.0298].And total Tp-SD of RVA group was significantly longer than that of control group[(7.6±6.5)%vs 2.26(1.62～3.51)%,P=0.0423].④The curves of torsion velocity in the pacing groups were obviously disorganized compared with control group.But there were no statistical differences in Ptv(peak twist velocity),Putv(peak untwisting velocity),Tptv(time to peak twist velocity)and Tutv(time to peak untwisting velocity)among the three groups.Conclusions The RV pacing tends to impair torsional synehrony of LV and depress LV torsion,though it doesn't change the timing of LV torsion.It may impair LV systolic and diastolic function.

ObjectiveTo evaluate left ventricular (LV) function and dyssynchrony in patients with dilated cardiomyopathy (DCM) and complete left bundle branch block (CLBBB) by three-dimensional speckle tracking imaging(3D STI).Methods3D STI was performed and analyzed using TomTec 4-D LV analysis 3.0 software in 37 DCM patients with CLBBB and 25 healthy volunteers.The global 3D,longitudinal,circumferential,radial strains were measured.LV dyssynchrony was evaluated by the standard deviation of time to peak from 3D strain of 16 segments related to the heart cycle(3D-SDI).ResultsIn control group,uniformity in the average value of 3D strain was observed between apical,mid-ventricular and basal levels (P ＞ 0.05).Global 3D,longitudinal,radial and circumferential strains had excellent correlations with LV ejection fraction ( r =- 0.92,- 0.84,- 0.78 and 0.81,respectively,P ＜0.01).Compared with control group,global 3D,longitudinal,radial and circumferential strains were significantly lower in DCM patients ( P ＜0.01 for all).3D-SDI in DCM patients with CLBBB was significantly longer than that of volunteers ( P ＜0.01).3D-SDI increased with worsening LV systolic function regardless of QRS duration (P ＜0.05).ConclusionsWhen image quality is optimal,3D STI represents a promising novel technique for assessment of global LV function and dyssynchrony.

Objective To investigate the value of real-time three-dimensional echocardiography 17 regional volume curves index in patients with heart transplantation. Methods Sixty patients with heart transplantation (no rejection), ten patients with heart transplantation (rejection), forty subjects with normal left ventricular(LV) function were examined by Philips iE33 with a X3-1 probe. Results Parameter index of 17 segment time to minimal systolic volume in patients with heat transplantation (rejection) were more than those in patients with heart transplantation (no rejection) and in subjects with normal LV function(all P <0.05). Parameter index of 17 segment time to minimal systolic volume were not significantly different in patients with heart transplantation (no rejection) compared with subjects with normal LV function. Parameter index of Tmsv16-SD (%), Tmsv12-SD (%) and Tmsv6-SD (%) show higher sensitivity and specificity for forecast rejection after heart transplantation. Conclusions Real-time three-dimensional 17 regional volume curves index can fast forecast early rejection after heart transplantation.

Objective To investigate the pathogenicity of late-onset Alzheimer disease from the viewpoint of comparative proteomic technology and to screen it from diseases with related protein markers.Methods Cerebral cortex tissue of temporal layer of 8 cases of late-onset Alzheimer disease and 5 cases of age-matched autopsied controls with normal brain was chosen for this study.Cerebral proteins were run through immobilized pH gradient (IPG) isoelectric focusing electrophoresis as the first dimension and then vertical SDS-PAGE electrophoresis as the second dimension.Differential proteins were identified with visionworks LS and then analyzed with matrix assisted laser desorption ionization time of flight mass spectrometry(MALDI-TOF-MS) and eleetrospray ionization mass spectrometry (ESI-MS).Finally,the protein was identified by searching in the data bank.Results Different 2-dimensional gel electrophoresis maps were obtained for the protein spots in the late-onset Alzheimer disease group and the control group gels.11 protein spots showed a significantly differential expression between the two groups of cerebral cortex samples.It was found that the expression of DJ-1 protein was increased in the late-onset Alzheimer disease group in comparison with the control group after searching in the database.Conclusion DJ-1 protein may be a potential marker related to Alzheimer disease pathogenicity.This finding would be helpful to develop new drugs which focus on this protein and prevent nearodegeneration.
