Cardiovascular disease (CVD) is one of the major complications of type 2 diabetes mellitus (T2DM), which results in a high risk of mortality. Thus, the cardiovascular safety of new anti-diabetic agents has become an important prob?lem with wide concern. There are two classes of incretine-based medications: glucagon-like peptide-1 receptor agonist (GLP-1RA) and dipeptidyl peptidase-4 (DPP-4) inhibitor (DPP-4I). It has been demonstrated that GLP-1RA and DPP-4I possesse beneficial actions in both animal models of cardiovascular dysfunction and patients with ischemic heart diseases. However, their effects on the cardiovascular system in diabetic patients with heart diseases are still uncertain. Here, we sys?tematically reviewed the effects of GLP-1RA and DPP-4I on cardiovascular system to provide more evidence of incretin-based therapy application for diabetes and complications.

OBJECTIVE:To explore the effect of health intervention on blood pressure,medication compliance and the quali-ty of life in elderly patients with hypertension. METHODS:64 elderly patients with hypertension were selected and randomly divid-ed into observation group and control group,with 32 cases in each group. Both groups were given Amlodipine besylate tablet 5 mg,qd. Control group received routine hypertension knowledge education and regular recheck by guidance. Observation group addi-tionally received health intervention on the basis of control group. The blood pressure control,cognitive level of patients to hyper-tension,medication compliance,the level of trust in physicians and quality score of life were compared between 2 groups before and after intervention. RESULTS:There was no statistical significance in systolic blood pressure and diastolic blood pressure be-tween 2 groups before intervention (P>0.05). After intervention,systolic blood pressure and diastolic blood pressure of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in cognitive level of patients to hypertension,medication compliance,the level of trust in physicians and quality score of life between 2 groups before intervention (P>0.05). After intervention,the observation group was better than the control group in terms of cognitive level of patients to hypertension,medication compliance,the level of trust in physicians and quality score of life,with statistical significance(P<0.05). CONCLUSIONS:Health intervention can effec-tively improve the cognitive level of elderly patients with hypertension to hypertension,improve the medication compliance and the level of trust in physicians,control blood pressure and improve the quality of life.

BACKGROUND: The neurological basis for learning and memory is the high plasticity of central nervous system, and special rehabilitative training is necessary in the process of the functional recombination of central nervous system.OBJECTIVE: To observe the capability of rehabilitative training in differentiating learning ability and memory maintaining of one-trial passive avoidance response, and its correlation with the kinetic properties of Nmethyl-D-aspartic acid (NMDA) receptor channel of contralateral hippocampal neuron in rats with cerebral infarction.DESIGN: A randomized control animal trial.SETTING: Department of Rehabilitative Medicine, Affiliated Hospital of Luzhou Medical College.MATERIALS: The experiment was carried out in the central laboratory of Luzhou Medical College between March 2000 and February 2002. Twentyfour male Wistar rats were randomly divided into three groups with 8 rats in each: free movement after cerebral infarction group (model group), rehabilitative training after cerebral infarction group (rehabilitation group) and normal group.METHODS: ① Model establishment: Rats in the model group and rehabilitation group were made into models of infarction of right middle cerebral artery, and those in the normal group were not given any treatment. ②Rehabilitative training: After 4 days, only the rats in the rehabilitation group were trained with rolling-cage exerciser, screen exerciser and balance exerciser for 4 weeks. ③ Learning and memory tests: The learning and memory performances of all the rats were tested at 35 days postoperatively. The Y-maze test was applied to mainly observe the needed number f training for the rats to reach 9/10 correct response (for running to dark arm), and the multi-functional conditioned reflex box to observe the stayed duration on the diving board (step-through latency). ④ The single channel current property of NMDA receptor in hippocampal neurons was recorded with cell adhesion after learning and memory tests.MAIN OUTCOME MEASURES: ① training times needed for the rats to grasp the structure of the maze in each group; ② step-through latency in each group; ③ single channel current property of NMDA receptor in each group.RESULTS: All the 24 rats were involved in the analysis of results. ① The training times needed for the rats to grasp the structure of the maze in the rehabilitation group and normal group were significantly different from that in the model group [(68.02±11.67), (57.62±10.31), (107.07±16.32) times, P ＜0.05], and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ② The medians of step-through latency before shock in the rehabilitation group and normal group were significantly different from that in the model group (286.7 s, 298.4 s, 126.7 s, P ＞0.05), and there was no significant difference between the rehabilitation group and normal group (P＞0.05). ③ The 35 pS short open NMDA receptor channel mainly existed in the hippocampal neurons of rats in the rehabilitation group, the open proportion was 0.099±0.007. The duration and proportion of 20 pS short and long open and the 35 pS short open NMDA receptor channels in the hippocampal neurons of rats were not significantly different from those in the normal group (P＞0.05). In the model group, 20 pS open channel was mainly observed, and the durations of 20 pS short and long open channels were obviously shorter than those in the rehabilitation group, the open proportion of 35 pS short open channel was 0.036t0.04, which was lower than that in the rehabilitation group,but no 35 pS long open channel was observed.CONCLUSION: Rehabilitative training accelerates the recovery of the learning and memory abilities of rats with cerebral infarction by changing the NMDA receptor channel properties of contralateral hippocampal neurons.

As a new biomarker and a member of transforming growth factor super family,growth differentiation factor-15 (GDF-15) is increased in some pathological situations,and plays a positive role.Increasing evidence from animals and clinical trials has indicated that GDF-15 is a promising biomarker to be used for diagnosis,screening,risk stratification and prognosis evaluation in acute coronary syndrome,heart failure and pulmonary vascular diseases.However,there are still numerous challenges and problems need to be resolved in the future,such as appropriate cut-off value in diagnosis and risk stratification in different cardiovascular diseases,improvement in sensitivity and specificity,and combinational application with other biomarkers.

BACKGROUND:Soft tissue releasing is a major means of correcting knee flexion contracture, and the soft tissue releasing methods are different for different knee joint diseases and degrees of deformity. Ideal soft tissue balance can gain a clear functional recovery and deformity correction from severe knee flexion contracture after total knee arthroplasty.
OBJECTIVE:To study the proper handling of knee flexion contracture and soft tissue releasing in total knee arthroplasty.
METHODS:Twenty-six cases of knee deformity in 20 ° to 60 ° receiving primary total knee arthroplasty were retrospectively studies. Steps of soft tissue releasing and residue deformity after each step were recorded. Postoperative fol ow-up was 12 months on average.
RESULTS AND CONCLUSION:The 26 cases were recovered from knee flexion deformity after soft tissue release. Posterior capsular release was carried out in al cases to different extents, and the flexion deformity and postoperative range were corrected and greatly improved, respectively. These indicate that the posterior capsular release and lateral col ateral ligament release can correct most of the flexion deformity, but increasing the distal femoral osteotomy is not necessary.

Osteoarthritis (OA) is a common chronic arthritis, mainly suffering the middle and elderly patients, and it is the main cause of arthralgia and articular functional disturbance. Studies have suggested that osteophyte formation was closely con?nected with the development of OA due to the stabilization of suffered joints and arthralgia induced by osteophytes. In tissue con?stitution and pathology, osteophyte is made up of bone, cartilage and connective tissue, stemming from MSCs. With the develop?ment of osteophytes, the proportion of bone increases while the proportion of cartilage and connective tissue decreases. What's more, in promotion factors of osteophytes, osteophyte formation was induced by the biomechanical and biochemical factors and their both effect. The biomechanical factors result from imbalance of articular biomechanics induced by cartilaginous degeneration and ligament trauma. And the biochemical factors result from alteration of articular microenvironment induced by metabolic disor?der of chondrocytes and synovitis. Furthermore, the both effects that the biomechanical factors induces biochemical alterations al?so co?promote osteophyte formation. And studies on the mechanism indicated that osteophyte formation was regulated by several signaling pathways and cytokines. TGF?β superfamily and Hedgehog signaling pathway were involved in modulating osteophyte formation. TGF?βand BMPs modulated the initiation and late stage of osteophyte formation respectively. And Hedgehog signaling pathway regulated the osteophyte formation with modulating the hypertrophy of chondral osteophytes. This paper emphatically re?views the development and mechanism of osteophytes in OA for deeply understanding the OA and bringing new ideas and methods for the precaution and treatment of OA.
