Objective To observe the therapeutic effects of endovascular stenting on the patients with drop attacks caused by carotid artery or vertebra-basilar artery stenosis.Methods Two drop attacks patients,who were diagnosed with symptomatic carotid artery or vertebra-basilar artery stenosis by DSA,were performed endovascular stenting.Case one had four serious artery stenoses at basilar artery,left vertebra artery and subclavian artery.Case two had double internal carotid artery.Six stents were placed,and filter protection devices were used in case two.After operating,the flowing up was performed for nine months or two years.Results The clinical symptoms of two patients were disappeared after operation.Case one performed flowing up for 9 months after operation,but he died by infarction of brain stem for his irregular taking medicine for 3 months since 6 months after operation.During flowing up for 2 years,case two was no relapse and no restenosis by DSA peoformed at 1 year after operating.Conclusions Endovascular stenting is a safe and efficient method for treating the patients with drop attacks caused by carotid artery or vertebra-basilar artery stenosis.

Objective:To explore the relationship between neuroticism and depression, and the mediating effect of coping style.Methods:A total of 274 prision inmates of Fujian province were tested by self-rating depression scale, Eysenck personality questionnaire and coping style questionnaire.SPSS 23.0 was used for data analysis, and Mplus 7.0 was used for structural equation modeling and Bootstrap mediating test.Results:(1) The scores of neuroticism, positive copying style, negative coping style and depression were 11.08±5.51, 32.47±6.45, 28.81±5.96, 41.15±9.07, respectively.Neuroticism was negatively correlated with positive copying style( r=-0.40, P<0.01) and positively correlated with negative coping style( r=0.39, P<0.01) and depression( r=0.69, P<0.01). (2)Neuroticism positively predicted depression and could explain 46.4% variation of depression score( F=46.372, P<0.01). (3)Coping styles (positive coping style and negative coping style) had partial mediating effects between neuroticism and depression.The whole model was well fitted (χ 2/ df=2.364, RMSEA=0.070, NFI=0.993, CFI=0.996, RFI=0.955, IFI=0.996), and the effect size of positive coping style and negative coping style were 0.108(95% CI: 0.061-0.157) and 0.066(95% CI: 0.021-0.109). Conclusion:Neuroticism directly affects depression and indirectly affects depression by means of positive coping style and negative coping style.

Objective To evaluate the left ventricular diastolic dysfunction by tissue Doppler imaging (TDI)in a suprarenal abdominal aortic coarctation model of Lewis rats. Methods Thirty male Lewis rats at age of 8 weeks were used. Myocardial hypertrophy model was obtained by suprarenal abdominal aorta banding with ligation. Mitral annular velocity measurement by TDI and regular two-dimensional echocardiography with M mode were examined at baseline and at 10-,20-,30-and 40-day post banding.Results Compared with baseline,the left ventricular end diastolic and end systolic wall thickness and ventricular dimension were progressively increased,while ejection fraction(EF)and fraction shortening(FS)were decreased(P＜0.0 1).The left ventricle demonstrated centrifugal myocardial hypertrophy.Peak myocardial systolic velocity(Sa)at the mitral annulus did not change significantly throughout this study and there was no significant correlation with EF(r=0.216,P=0.071),and peak myocardial early diastolic (Ea),late diastolic(Aa)at the mitral annulus and Ea/Aa indices also were not stable after aortic banding and there were no significant difference in repeated measures at different time(P＞0.05).But the E/Ea wasincreased and the index had a statistically significant difference(P＜0.001).Conclusions The left ventricleshowed centrifugal myocardial hypertrophy in Lewis rats with abdominal aortic banding.E/Ea radio was a sensitive and stable index to evaluate left ventricular diastolic dysfunction.

Objective:To investigate the anti-inflammation effects by activation of the cholinergic anti-inflammatory pathway and its mechanisms in non-alcoholic steatohepatitis (NASH)model mice.Me-thods:6-week-old male C57BL/6J (B6)mice were randomly divided into four groups:the first group was normal mice,injected with saline;the second group was normal mice,injected with nicotine;the third group was NASH model mice,injected with saline;the fourth group was NASH model mice,injec-ted with nicotine.The experimental mice were fed with either standard chow (SC)or high-fat and high-fructose (HFHF)for 17 weeks to generate an NASH model mice.The mice received injection once daily for 3 weeks [nicotine dose,400 μg/kg].Then,their pathological characteristics and function of the liver were assessed.The expressions of interleukin-6 (IL-6)and tumor necrosis factor-α(TNF-α)in se-rum were analyzed by enzyme linked immunosorbent assay (ELISA).The expressions of alpha 7 nicotinic acetylcholine receptors (α7nAChR),Toll-like receptors-4 (TLR-4)and nuclear factor κB of phosphory-lation (p-NF-κB)in Kupffer cells were determined by Western blot and immunofluorescence assays.Re-sults:We successfully generated NASH model mice by imitating the high-fat and high-fructose dietary style of NASH patients.The results of our investigation demonstrated that nicotine could reduce signifi-cantly the levels of IL-6,and TNF-αin serum (P <0.05).The expression of p-NF-κB protein in the group which was NASH model mice injected with nicotine declined significantly as compared with the group which was NASH model mice injected with saline (P <0.05).And the expression of α7nAChR protein elevated significantly conversely (P <0.05 ).Conclusion:Activation of the cholinergic anti-inflammatory pathway could inhibit the release of inflammatory factors as TNF-αand IL-6 in NASH model mice,and the mechanism for the inhibition of inflammatory was mediated by NF-κB pathway.

Objective To explore the influence of studying in the elderly university on the cognitive function for elderly. Methods Elderly university group (EUG) was consised of 105 subjects aged ≥60 who studied in the elderly university for one year. Controlled group(CG) was consisted of 105 elderly over 60 years of age who were siblings for subjects and would not studied in elderly university. Meanwhile, it was excluded if they were working. Two groups were excluded depression patients before study. The assessment tools were composed of Center for epidemiological survey of depression scale (CES-D), activity of daily living scale(ADL), mini-mental state examination (MMSE)and Wechsler's adult intelligence scale(WAIS). There were no significant statistics difference in scales of CES-D, ADL, MMSE and WAIS between two groups. Results There were no significant statistics difference of CES-D, ADL and MMSE between two groups after a year, however, the scales of ADL for controlled group after one year was higher than that before one year( t = 2. 191, P = 0.031 ). The MMSE mark shows one(0.95% )sustain cognitive impairment in EUG after one year; meanwhile there were six elders of (5.77%)come up to critical value of cognitive impairment in CG, the difference was almost statistical significance (P=0. 058 ). The WAIS mark demonstrated the total scale, VQ scale and PQ scale was declining. The score of total scale and perform scale of WAIS in CG were (110.3 ±8.2 )and (110.9 ±7.7) respectively. The score of total scale and perform scale of WAIS in CG were ( 107.8 ± 9.6 ) and ( 107.9 ± 13.4 ) respectively. There were significant difference between two groups(P=0. 044, P=0. 049). Furthermore, after one year the score of total scale of WAIS in CG( 110. 6 ± 7.4 ) outstanding be lower than that one year ago(P = 0. 022 ). There was no significant means for the total scale , verbal scale and perform scale of WAIS in CEG before and after year.Conclusion The program of continue education may play a positive role to stay or to improve the descending of the cognitive function in the elderly.

Objective To explore the significance of peritubular capillary C4d deposition in histopathological changes, renal function and prognosis of the patients with antibody-mediated chronic rejection (AMCR). Methods Deposition of C4d in the kidney was examined by irnmunohistochemistry on routine paraffin-embedded sections using anti-C4d polyclonal antibody. Seventy-seven patients were divided into C4d+ group (n = 35) and C4d- group (n = 42). The relationship of C4d and renal function,histopathological changes and prognoses of allografts were analyzed. Results The number of patients with tubular atrophy and glomerular basement membrane proliferation in C4d+ group was significantly more than that in C4d group (P＜0.05). Mean serum creatinine level was significantly higher in C4d+ group than in C4d- group 12 months after renal transplantation [(379.1 + 260.2)μmol/L vs (260.5 + 175.3) μmol/L, P＜0.05]. According to Kaplan-Meier analysis, the one-year graft survival rate was lower in the C4d+ group (62.9% ) than in the C4d- group (83.3% ) (logrank P＜0.05). Conclusion Patients with C4d deposition are associated with tubular atrophy and glomerular basement membrane proliferation. The serum creatinine level in C4d+ patients was significantly higher than in C4d- group at the 12th month after transplantation. More patients with C4d deposition lost their grafts during the study period.

ObjectiveTo investigate the efficacy of rapamycin combined with CsA/Tacrolimus (Tac) in chronic allograft nephropathy (CAN).MethodsFifty-three cases of CAN accepted the quadruple immunosuppressive drug program,which contained rapamycin combined with CsA/Tac and MMF and prednisone,and CsA/Tac and MMF were reduced to the original amount of 25％ to 50％.After treatment for 12 months,more relevant indicators,including serum creatinine,glomerular filtration rate,serum cholesterol,triglycerides,urinary protein,GPT and bilirubin and other changes were observed.ResultsIn the patients receiving quadruple regimen of rapamycin during 12 months,the blood Ccr was decreased from (161.51 ± 106.48)μmol/L before treatment to (126.51 ± 56.2)μmol/L after treatment for 6 months (P＜0.05) and to (123.43 ± 54.18)μmol/L after for 12 months (P＜0.01).The GFR was increased from (0.754 ± 0.302) ml/s before treatment to (0.952 ± 0.347)ml/s after treatment for 6 months (P＜0.05) and to (1.007 ± 0.394) ml/s after treatment for 12 months (P＜0.01).Cholesterol and triglycerides in patients had no significant change before and after treatment.The positive rate of proteinuria after treatment showed an increasing trend from 9.4％ before treatment to 26.4％ after treatment for 12 months.ConclusionThe quadruple program of rapamycin combined with CsA/FK506 and MMF can significantly improve Ccr and GFR in patients with CAN,but it can increase the incidence of proteinuria in patients:

Objective To study the effects of exercises training on the recovery of neurological function and the expression of matrix metalloproteinase-9 (MMP-9) in perihematomal brain tissue after intra cerebral hemorrhage (ICH) in rats. Methods Sixty-four male adult Sprague-Dawley rats were randomly divided into exercises group and control group. ICH model was induced by autobiood injection. The rats in exercises group were given balance, grasping and walking exercises every day. The rats in control group exercised freely in standard cages. Neurological function in both groups was measured at the 3rd, 7th, 14th and 21st d. All the rats were sacrificed and the concentration of MMP-9 was measured with immunohistochemical method and in situhybridization. Results In both groups neurological function scores was lowest at the 3rd d, were highest at the 21st d. There was no significant difference between two groups at the 3rd d, but at the 7th, 14th and 21st d the differences between two groups were significant ( P < 0.05 ). In exercises group, MMP-9 expressed weakly at the 3rd d, and peaked at the 7th d, then declined gradually. In control group, MMP-9 expression peaked at the 3rd d, then decreased slowly. MMP-9 protein expression was in accord with mRNA. MMP-9 expression in exer-cises group was significantly different from control group on the 3rd and 7th d (P < 0.05 ) , but not at the 14th and 21st d ( P > 0.05 ). Conclusions Early exercises can inhibit the expression of MMP-9 that could play a role in protecting neurons. Daily exercises can stimulates the expression of MMP-9 so as to have a positive role in midstage of disease. MMP-9 may be involved in tissue remodelling and vascular repairing, which prompt neu-rofunction recovery.

In order to investigate the effects of rhGM-CSF on apoptosis of HL-60 cells induced with VP-16 treatment, HL-60 cells were first incubated with rhGM-CSF before they were treated with VP-16. The apoptosis processes and the changes in apoptosis related gene bcl-2 and fas expression were observed. The morphological and ultrastructural changes were observed under optics microscope and electromicroscope. DNA fragmentation were detected by agarose gel electrophoresis, the apoptotic rate, bcl-2 and fas expression with flow cytometry. Our results showed that rhGM-CSF inhibited the apoptosis of HL-60 cells induced with VP-16 treatment, which enhanced the down-regulation of bcl-2 expression, but inhibited the up-regulation of fas expression. So it suggested that rhGM-CSF can decrease the sensitivity of HL-60 cells to VP-16, probably by down-regulation of fas expression.

OBJECTIVE: To explore the relationships between the sphenoid-sinus-o-tumoropathy and local anatomy, as well as the characteristics of invasive damages of nerve system in sphenoid-sinus-o-tumoropathy, and emphasize that it is crucial of early diagnosis and surgery for sphenoid-sinus-o-tumoropathy.
