Objective The purpose of this study was to assess the effectiveness and safety of distal filtration protection devices during carotid artery stenting.Methods Between June and July in 2002, carotid artery stenting (CAS) were performed in 4 patients with asymptomatic severe carotid artery stenosis. Self-expendable stents (Smart, Cordis) and distal filtration devices (Angioguard XP, Cordis) were used in all patients. Primary endpoints were perioperative neurologic complications and mortality. Data were collected prospectively.Results All patients were male, their age were 59?4 years old. One patient had history of transient ischemic attacks(TIAs); and another had inferior myocardial infarction, and right coronary intervention was performed before CAS, and another one underwent CABG 6 months ago. There were two right internal carotid and two left internal carotid severe lesions (82.5?6.0)% were treated. The filtration devices and stents were delivered and deployed successfully in all target artery (technical success rate was 100%) and

Objective To discuss the role of matrix metalloproteinase-8(MMP-8) mRNA in apical granuloma and periapical cyst by detecting the its expressions in the periapical granuloma and periapical cyst.Methods Reverse transcription polymerase chain reaction(RT-PCR) technique was used to measure the expressions of MMP-8 mRNA in 22 cases of periapical granuloma,11 cases of periapical cyst and 10 cases of normal periapical tissues.Results The positive rates and the levels of MMP-8 mRNA expression in apical granulomas and periapical cysts were significantly higher than those in normal tissues(P0.05).Conclusion The expression of MMP-8 may play an important role in the pathogenesy of apical granuloma and periapical cyst,and it may be involved in the process of bone destruction.

Objective To investigate the correlation between vitamin E and community acquired pneumonia (CAP) .Methods A total of 128 cases of CAP(CAP group) and 135 people undergoing the healthy physical examination (excluding CAP ,control group) in our hospital from Jan .2016 to Dec .2016 were chosen .Each group was divided into the age subgroups of 0-17 years old ,18-40 years old and 41-65 years old .Vitamin E ,Chlamydia pneumoniae(CPn) and mycoplasma pneumoniae(MP) were detected in all the subjects .Then the obtained data were statistically analyzed .Results The average vitamin E was (15 .43 ± 4 .37)mg/L in the control group and (6 .37 ± 3 .24)mg/L in the CAP group ,the difference between the two group was statistically significant(P<0 .05) .In the control group ,there were 7 cases of MP positive and 6 cases of CPn positive .In the CAP group ,there were 32 cases of MP posi‐tive and 25 cases of CPn positive .The differences of MA and CPn positive between the two groups were statistically significant(P<0 .05) .The vitamin E levels in the 0 -17 years old ,18 -40 years old and 41 -65 years old subgroups of the control group were (14 .75 ± 4 .12) ,(16 .42 ± 4 .35) ,(16 .42 ± 4 .35)mg/L respectively ,while which in the various subgroups of the CAP group were (5 .43 ± 3 .18) ,(7 .74 ± 3 .65) ,(7 .74 ± 3 .65)mg/L respectively ,the difference in different age groups between the two groups was statistically significant(P<0 .05) .Conclusion Maintaining a high level of serum vitamin E level could effectively prevent CAP .

Objective To detect the plasma macrophage inflammatory protein (MIP) levels in patients with early Parkinson' s disease (PD) and to investigate whether plasma MIP was associated with motor and non-motor symptoms in early PD.Methods Fifty-nine patients with early idiopathic PD (Hoehn-Yahr Staging Scale from 1.0 to 2.5) treated in our hospital from January 28,2013 to September 30,2013 and 54 healthy controls were recruited.Plasma MIP-1α and MIP-1β levels were measured by enzyme-linked immunosorbent assay.Motor function was assessed by Unified Parkinson' s Disease Rating Scale Part Ⅲ and Hoehn-Yahr Staging Scale during “on” period.Total non-motor symptoms were assessed by Non-motor Symptoms Questionnaire.Cognitive dysfunction was assessed by Mini Mental State Examination.Autonotic dysfunction was assessed by Scales for Outcomes in Parkinson' s disease-Autonomic.Depression was assessed by Hamilton Depressive Scale (HAMD).Rapid eye movement (REM) sleep behavior disorder was assessed by REM sleep behavior disorder screening questionnaire (RBDSQ).Correlation between plasma MIP levels and scale scores was analyzed by Spearman rank correlation.Results Plasma MIP-1o and MIP-1β levels were not significantly different between early PD patients and healthy controls.However,plasma MIP-1 α level negatively correlated with depression (HAMD score,r =-0.520,P =0.027) and rapid eye movement sleep behavior disorder (RBDSQ score,r =-0.537,P =0.039).Conclusion MIP-1 α may be correlated with depression and RBD in early PD.

In this paper, a reflection type photoelectric pulse wave sensor was designed for short-term pulse rate variability analysis. Photoplethysmography (PPG) signals and ECG signals (obtained with the Dimetek MicroECG recorder Dicare-m1CP) were recorded synchronously from 20 healthy subjects. The analytical results show a significant correlation (correlation coefficient r > 0.99) between the PPG-derived peak-to-peak (PP) intervals and the ECG-derived RR intervals. Besides, there are no significant differences (P > 0.05) between the HRV measured by ECG and the PRV quantified by the PPG whether in time domain, frequency domain, or the Poincaré plot parameters. The experimental results suggest that the PPG-based short-term PRV analysis can be consistent with the ECG-based HRV measurement in wearable smart devices.

Objective To estimate the diagnostic value of interstitial infiltration pattern for early morphea.Methods Twenty-five cases of early morphea pathologically characterized by interstitial infiltration of inflammatory cells were collected from 2010 to 2012.The clinicopathological features of these cases were retrospectively analyzed.Results The average clinical course was 7.5 months.The primary manifestation was edematous dark erythematous plaques,and interstitial or mixed infiltrate of inflammatory cells was the characteristic histopathological presentation.After anti-inflammatory treatment,lesions markedly improved or disappeared in 70％ of these patients.Conclusions Interstitial infiltration of inflammatory cells is a rare histologic pattern in early morphea.To learn and recognize this pattern may be beneficial to the diagnosis and treatment of early morphea.

Objective To investigate the effect of trichostatin A on the expression of growth arrest and DNA damage-inducible protein 45 alpha (Gadd45α) in,proliferation of and apoptosis in a human epithelial carcinoma cell line A431.Methods Cultured A431 cells were treated with different concentrations (0.05,0.1,0.25,0.5,1 μmogL) of trichostatin A for various durations (6,12,24,48 hours).Subsequently,cell proliferation,cycle and apoptosis were detected by cell counting kit-8 (CCK8) and flow cytometry respectively.The expression of Gadd45eα mRNA and protein in cultured A431 cells was detected by reverse transcription-PCR and Western blot respectively.Results Trichostatin A inhibited the proliferation of A431 cells in a dose (0.05-1.0 μmol/L)-dependent manner at all the 4 time points (F =3554.71,P ＜ 0.05),as well as in a time (6-48 hours)-dependent manner at these tested concentrations (F =1685.18,P ＜ 0.05).A statistical increase was induced in the early apoptosis rate,late apoptosis rate and Gadd45α mRNA expression in A431 cells by the 24 hour-treatment with trichostatin A of 0.1 to 0.5μmol/L.Elevated percentage of cells at G1 phase (26.910％ ± 0.799％,30.406％ ±0.625％,32.896％ ± 0.599％ vs.21.633％ ± 1.144％,F =105.93,P ＜ 0.05) and expression of Gadd45α protein (0.6536 ± 0.2193,0.6990 ± 0.0110,0.9040 ± 0.1971 vs.0.3766 ± 0.0241,F =332.88,P ＜ 0.01) were observed in A431 cells treated with trichostatin A of 0.1,0.25 and 0.5 μmol/L for 24 hours compared with untreated A431 cells.Conclusions Trichostatin A can enhance the mRNA and protein expression of Gadd45α in A431 cells,which may be involved in the suppression of cell proliferation as well as acceleration of apoptosis of A431 cells by trichostatin A.
