Objective To investigate the clinical value of the intervertebral disc morphous in patients with thoracolumbar vertebral compression fracture. Methods The MRI, X-ray and CT data of 75 patients with thoracolumbar vertebral compression fracture were retrospectively analyzed. The intervertebral disc damage degree was observed, and its correlation with vertebral fracture degree and endplate damage degree was studied. The vertebral body leading edge height, intervertebral space height and back convex Cobb angle in patients with different intervertebral disc damage degree were measured. Results The intervertebral disc damage degree height was positively correlated with endplate damage degree (P<0.01), and the intervertebral disc damage degree was positively correlated with fracture degree (P<0.01). With the increase of the intervertebral disc damage degree in patients with Ⅰ - Ⅳtype intervertebral disc damage, the vertebral body leading edge height and intervertebral space height gradually became smaller: (0.68 ± 0.05), (0.61 ± 0.03), (0.58 ± 0.03), (0.42 ± 0.05) mm, and (0.31 ± 0.06), (0.29 ± 0.03), (0.24 ± 0.06), (0.22 ± 0.02) mm, and there were statistical differences (P<0.05). There was no statistical difference in back convex Cobb angle in patients with different intervertebral disc damage degree (P>0.05). Conclusions It is more important to observe the morphological changes of the intervertebral disc in patients with thoracolumbar vertebral compression fracture, and the damage degree is closely related with the vertebral fracture degree and endplate damage degree.

Objective To explore the effect of cognitive-behavioral method on healthy behavior selection of in-patients with type 2 diabetes. Methods All patients with type 2 diabetes involved in this study were divided into the experimental group(99 patients) and the control group(96 patients). The experimental group was given health education with cognitive behavioral method, and the control group received only common health education. The comparison on the knowledge about diabetes mellitus and indicators of glucose metabolism on the first and 6th months between the two groups was performed. Results The knowledge about diabetes mellitus and indicators of glucose metabolism on the first and 6th months in the experimental group were better than those in the control group. Conclusions Cognitive-behavioral method can increase the treatment compliance of in-patients with type 2 diabetes and improve the glucose metabolism indicators, and created favorable condition for prevention of diabetes complications.

BACKGROUND:Fragile bone in senile osteoporosis patients easily weakened pedicle screw fixation capacity. Therefore, bone cement leakage and screw removal cannot be solved during pedicle screw repair in osteoporotic patients with degenerative lumbar spine. OBJECTIVE:To investigate the biomechanical properties of novel pourable pedicle screws and bone cement application effect in osteoporotic patients with degenerative lumbar spine. METHODS:Six lumbar specimens (T11-L5) at the mean age of (72.9±4.2) years were selected, total y 42 vertebrae. The average bone density was 0.696 g/cm2. Any side of al vertebrae was inserted with pourable pedicle screws. 2 mL of bone cement was perfused under the X-ray fluoroscopy with cement push rod and fil ing cylinder. The same number of conventional screws was inserted into the opposite side of the samples. Three-point bending test was performed in two kinds of screws. The maximum vertebral axial pul out force test and the maximum spin torque test were conducted in vertebra to observe the destruction of the vertebral body and implanted effect. RESULTS AND CONCLUSION:(1) The ultimate strength and yield load of novel pourable cement pedicle screws were significantly more than conventional screws (P<0.05). Ultimate displacement and yield displacement were significantly less in novel pourable cement pedicle screws than in conventional screws (P<0.05). (2) The maximum vertebral axial pul out force and the maximum spin torque were significantly higher in novel pourable pedicle screws than in conventional screws (P<0.05). (3) In summary, novel pourable cement pedicle screw is simple to operate, can effectively control bone cement penetration, and improve screw stability in osteoporotic vertebrae. Moreover, after treatment, the removal of screws is convenient, cannot evidently destroy vertebral body or screw channel, and promote early recovery.

Objective To detect the change of hemorrheology and prethromboticstate markers levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and to explore the pathogenic mechanisms of cardio-cerebrovascular thromboembolic diseases in OSAHS patients. Methods Polysomnography was performed in 86 patients with OSAHS and in 20 control subjects matched for age and body mass index. The patients with OSAHS were divided into mild group , moderate group , and severe group according to the apnea hypopnea index (AHI). Hemorrheology and prethromboticstate markers levels were measured in all the subjects for correlation analysis. Results The whole blood viscosity, erythrocyte aggregation index, and erythrocyte electrophoresis time in mild OSAHS group , moderate OSAHS group and severe OSAHS group were significantly higher than those in the control group. The whole blood viscosity, erythrocyte aggregation index, and erythrocyte electrophoresis time were also significantly different between the three OSAHS groups , increasing with the severity of OSAHS. Plasma viscosity was not significant difference between OSAHS groups and the control group. Plasma D-D , AT-Ⅲ and vWF levels were also not significant difference between OSAHS groups and the control group. Conclusions The change of hemorrheology in OSAHS patients may contribute to the vulnerability of patients to cardio-cerebrovascular thromboembolic diseases.

AIM:To explore the effect of water extract propolis(WEP)from Taishan on apoptosis of human umbilical vascular endothelial cells(HUVECs)induced in vitro by tumor necrosis factor-?(TNF-?).METHODS:HUVECs were collect by digestion-perfusion and cultivated.TNF-? at concentration of 50 ?g/L was administrated to induce the apoptosis of HUVECs.After injury,HUVECs were treated with WEP at concentrations of 50,100,and 200 mg/L,respectively,for 24 h.Apoptosis was evaluated by terminal-deoxynucleotidyl transferase mediated nick end labeling(TUNEL)and flow cytometry(FCM).RESULTS:Apoptosis index in injured group was significantly higher than that in control group,and decreased significantly after treating with WEP at concentrations of 50,100,and 200 mg/L,respectively(P

Objective: To investigate the effects of acupuncture and combined acupuncture and medicine on the quality of life and the genital endocrine level in postmenopausal women. Methods:Forty-seven patients were randomly assigned to acupuncture and acupuncture plus medicine groups,23 cases in the acupuncture group and 24 cases in the acupuncture plus medicine group. The observed course of treatment was 3 months. A Chinese concise SF-36 questionnaire was used to evaluate the quality of life in the different groups of patients before and after treatment.Meanwhile, radioimmunoassay was used to observe the differences in serum genital hormones:follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) contents between pretreatment and posttreatment in both groups. Results: After treatment, there was a significant difference in quality of life between the two groups and it was better in the acupuncture plus medicine group than in the acupuncture group(P＜ 0.01). E2 content increased more markedly in the acupuncture plus medicine group than in the acupuncture group(P＜ 0.05). There were no significant differences in FSH and LH contents between the two groups (P ＞ 0. 05). Conclusion: Both acupuncture and acupuncture plus medicine can improve the quality of life and increase obviously low E2 content in postmenopausal women. Acupuncture plus medicine raises the patients' quality of life and E2 content more markedly than acupuncture. It is suggested that both acupuncture and acupuncture plus medicine can improve the symptoms, signs, and physical and mental health, raise the quality of life and ameliorate genital-endocrine environment in postmenopausal women, but a combination of acupuncture and medicine has a better effect.
