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 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 study the etiology of functional dyspepsia (FD) and compare the clincial responses of medical treatment and psychological intervention.Methods Psychological intervention (psychologic support),advices for daily life (eating habits) and medical treatment were administered to the 346 FD patients;and the therapeutic effects were compared.Results Complete remission:225 cases (65%);partial remission:52 cases (15%);no effect:69 cases (20%).The overall effective rate was 80%.Conclusion FD is a clinical syndrome focusing in upper abdomen,but without local or systematic evidence Psychological treatment is stressed.

From the four aspects of residency training plan,the actual clinical teaching arrangement,clinical operation skill training and examination system,we compared the pros and cons of neurological resident training systems in two famous hospitals in Australia and China,aiming to provide useful suggestions to improve the current neurological resident training system.

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.

Objectives To investigate the recurrence risk factors and the protective factors of aortic dissection (AD) DeBakey type Ⅲ. Methods 43 patients with AD DeBakey type Ⅲ who were in Guangdong General Hospital from May 2014 to September 2014, were enrolled as the case group, while 27 volunteers exclude AD as the control group. Blood chemistries and other information obtained immediately after admissions , χ2 test or T test was used for univariate analysis of independent samples. Multivariate Logistic regression analysis was used to screen patients with recurrence risk factors or protective factors. Results The prevalence of hypertension (93.02%vs. 18.52%, P = 0.000) and proportion of smokers (34.88% vs. 11.11%, P = 0.027) were significantly higher in case group than control group. Logistic regression analysis showed that hypertension (OR=5.148, 95%CI= [2.209~13.058], P=0.001) and albumin level (OR=0.709, 95%CI = [0.541~0.929], P=0.013) were significantly associated with recurrence of aortic dissection DeBakey type Ⅲ. Conclusion Hypertension is an independent risk factor for recurrence of aortic dissection DeBakey type Ⅲ, and albumin level is a protective factor.
