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 evaluate the reliability and validity of Diabetes Diet-Related Quality-of-Life Scale (DDR-QOL) in Chinese version,in order to provide an efficient instrument for assessing the quality of life of diabetes in diet therapy.Methods Translating and edit the DDR-QOL scale initially,275 eligible subjects were invited to the study.DDR-QOL scale and 36 item Short Form Health Survey (SF-36) were used to collect data which were conducted for evaluating the internal consistency,reproducibility,construct validity,convergent and discriminant validity of DDR-QOL.Results The total Cronbach's α was 0.86.The factor analysis suggested good construct validity of DDR-QOL.Significant correlations were found between DDR-QOL and SF-36.The quality of life of diabetes who is on the job or not can be identified by DDR-QOL.Conclusions The Chinese version of DDR-QOL is a valid and reliable tool to assess the quality of life of diabetes who are in diet therapy.

Objective To investigate longitudinal systolic function of transplanted heart using two dimensional speckle tracking echocardiography and tissue Doppler imaging.Methods 56 consecutive patients with heart transplant were recruited,according to myocardial biopsy and 1 year's follow up,they were divided into non-rejection group (group A) and rejection group (group B).36 healthy controls (group C) were also randomly recruited.Left ventricular ejection fraction (LVEF),pulmonary arterial systolic pressure,tricuspid annular plane systolic excursion (TAPSE),tricuspid annular plane systolic velocity (TAS') and global longitudinal strain (GLS) were calculated via Qlab 9.0 analysis software offline.Results Compared with group C,LVEF was reduced in group B (P ＜0.01).Differences of GLS,TAPSE,and TA-S' among groups were all statistically significant (P ＜0.01),group B＜group A＜ group C.LVEF,TAPSE and TA-S' were correlated with GLS (r =-0.64,r =-0.69,r =-0.71 ; all P ＜ 0.01).Conclusions Left and right ventricles were a functional unity,the systolic function of which was impaired in patients with heart transplant.

AIM: To investigate the effects of dehydroepiandrosterone (DHEA) on experimental osteoarthritis in rats. METHODS: Forty rats were randomly divided into four groups. Group A is normal control group. Osteoarthritic models of rats were established by intraarticular injections of papain into the right knee joints of groups B, C and D. Then the right knee joints of rats in groups C and D, respectively, received 150 ?l intraarticular injections of DHEA at a concentration of 50 ?mol?L~(-1) and 100 ?mol?L~(-1), and the right knee joints of rats in groups A and B both received 150 ?l physiological saline, twice weekly for five weeks. Six weeks later, all rats were sacrificed, and the articular cartilage was assessed by gross morphologic, histologic, biochemical and immunohistochemical methods. RESULTS: The cartilage damage in groups C and D was much less than that in group B through observation under a surgical microscope. The Mankin's score, nitric oxide (NO) in the douche of articular cavity, malondialdehyde (MDA) in synovium, the expression of matrix metalloproteinase-1 and 9 in articular cartilage in groups C and D decreased in comparison with group B, and the foregoing indexes in group D decreased significantly compared with group C. However, the activities of superoxide dismutase (SOD) in the douche of articular cavity and blood serum in groups C and D increased in comparison with group B, and the foregoing indexes in group D increased significantly compared with group C. CONCLUSIONS:DHEA shows a cartilage-protecting effect which is in a dosage-dependent manner. The mechanism probably is to inhibit the expression of matrix metalloproteinases and to decrease the release of (NO and enhance the antioxidation.

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.
