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.

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.

Objective To quantitatively evaluate left ventricular layer-specific strain using speckle tracking imaging,and their relationship with age and gender in nornal subj ects.Methods GE Vivid E9 equipment with EchoPAC BT1 2 workstation were used.One hundred and nineteen healthy subj ects were enrolled in this study.Results Left ventricular global longitudinal and circumferential strain was highest in the endocardium and lowest in the epicardium.Longitudinal and circumferential 3-layer strain was highest in the apex and lowest in the base.Age and gender had little influence on the left ventricular layer-specific strain.Conclusions Speckle tracking imaging can quantitatively assess left ventricular layer-specific strain, providing another useful modality for evaluating cardiac 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.
