Objective To discuss the relationship of hypertension with ageing and comorbidities in 6426 inpatients. Methods The data of 6426 inpatients with hypertension from May 2005 to May 2009 were analyzed retrospectively. All inpatients were divided into four groups: the young-aged group from 18 to 44 yrs (n= 312, 4. 8%), the middle-aged group from 45 to 59 yrs (n= 1529,23.8%), the elderly group from 60 to 79 yrs (n=3847, 59.9%) and the old old group from 80 to 99 yrs (n=738, 11.5%). The percentages of hypertension patients in the same age group over the same period were calculated and the comorbidities were observed respectively. Results Of 6426 hypertensive cases, there were 3438 males (53.5%) and 2988 females (46.5%), ranging from 18 to 99 yrs with the average age of (66.3± 12. 1) yrs. There were 25 504 inpatients over 18 years old including 11 208 in the youth group, 5389 in the middle-aged group, 7596 in the elderly group and 1311 in the old old group. The proportions of hypertension inpatients to total in-patients in the four age groups were 2.8%, 28. 4%, 50.7% and 56.3% respectively. In the youth and middle-aged groups, numbers of males with hypertension were more than of females, however there was no significant difference in gender in the elderly and the old old groups. Within 6426 inpatients with hypertension, 2069 (32.2 %) had diabetes mellitus, 1508 (23.5%) had hyperlipidemia, 105 (1.6 % )had sleep apnea syndrome, 1061 (16.5%) had coronary artery disease, 904 (14.1%) had heart failure, 2353 (36.6%) had stroke and 678 (10. 6%) had kidney failure. Conclusions The prevalence of hypertension increases with ageing significantly. The correlated risk factors for hypertension include diabetes mellitus, hyperlipidemia and sleep apnea syndrome, being a clustering phenomenon, especially for elder patients. These risk factors also deteriorate the damage on heart,brain, kidney and other target organs, which might ultimately result in serious cardio-cerebral vascular events. Therefore, besides control of blood pressure, we should strengthen the complex treatment on hypertension to prevent and delay the occur of complicating diseases.

Objective To investigate the related risk factors in patients with atrial fibrillation in order to prevent and delay the occurrence of atrial fibrillation.Methods Five hundred and fifty-eight inpatients with atrial fibrillation were retrospectively analyzed from June 2005 to June 2008.They were divided into several groups according to the age and the characteristics of the elder patients with atrial fibrillation were analyzed.Results In the 558 cases with atrial fibrillation, there were 298 males (53.4%) and 260 females (46.6%) aged from 21 to 97 years.The average age was (72.8 ±10.1) years.There were 57 cases aged 21-59 years(10.2 %)and 501 cases aged 60-97 years(89.8 %).The total number of inpatients in our hospital was 11 869, and there were 4049 cases aged<60 years, 2527 cases aged 60-69 years, 3971 cases aged 70-79 years, 1244 cases aged 80-89 years and 78 cases aged>90 years.The proportions of the inpatients with atrial fibrillation in the above five age groups of inpatients were 1.4%(57 cases), 4.2%(107 cases), 6.6% (262 cases), 9.5%(118 cases)and 17.9% (14 cases), respectively.In 558 cases with atrial fibrillation, there were 230 cases (41.2%) with paroxysmal atrial fibrillation, 44 cases (7.9%) with persistent atrial fibrillation and 284 cases (50.9%) with permanent atrial fibrillation.The most common underlying disease was hypertension in the 558 cases, followed by coronary heart disease, heart failure, diabetes, rheumatic heart disease and so on.Conclusions The prevalence of atrial fibrillation is increased with aging.Hypertension, coronary heart disease, rheumatic heart disease, heart failure, hyperthyroidism,diabetes, chronic pulmonary disease and renal failure are all the risk factors for atrial fibrillation.

Objective To identify the significance of neuropsychological single-item scales in the diagnosis of mild cognitive impairment (MCI) and Alzheimer's disease (AD).Methods A total of 676 elderly people living around Dongzhimen district in Beijing were recruited using multistage sampling method.Cognitive function was assessed by minimum mental state examination (MMSE)and other scales.MCI was diagnosed based on the criteria proposed by Petersen (1999),and AD was diagnosed based on the NINCDS-ADRDA.Subjects were divided into normal cognitive group (n=213 cases,31.5％),Alzheimer's disease (AD) group (n=167 cases,24.7％),amnestic mild cognitive impairment (aMCI) group (n=186 cases,27.5 ％) and non-AD dementia group (110 cases,16.3 ％).Results The MMSE scores in AD,aMCI and normal groups were 23.0 ± 5.9,25.9±2.6,8.1 ± 1.7,respectively.There were significant differences in MMSE scores between AD,aMCI and NC groups separately (all P＜0.01).Compared with MCI and NC group,th scores of time orientation,attention,calculation and immediate recall and delayed recall were significantly decreased in AD group (all P＜0.01).Comparing with normal group,the scores of attention and calculation were reduced in aMCI group (both P＜0.01).The delayed story recall (DSR) scores in AD,aMCI and NC groups were 15.7 ± 11.7,7.6 ± 4.9,26.5 ± 9.3,respectively.There were significant differences in mean DSR scores between AD,aMCI and NC groups separately (all P＜0.01).Compared with normal group,the clinical dementia rating (CDR) scores were higher and the mean clock drawing task (CDT)scores were lower in AD and aMCI groups (both P＜0.01).Conclusions Both neuropsychological assessment tools such as MMSE and single-item scales such as delayed story recall have the certain significance in the diagnosis of MCI and AD.

Objective To extract high quality genomic DNA of Cordia dicholoma seeds by using different methods;To provide references for researches on genomic DNA of Cordia dicholoma seeds. Methods Genomic DNA of Cordia dicholoma seeds was extracted through improved CTAB method and improved SDS method. Purity and concentration of obtained DNA were detected by spectrophotometry and agarose gel electrophoresis. Results The results of spectrophotometry showed that the purity of genomic DNA obtained through improved CTAB method was better than improved SDS method. Genomic DNA extracted through improved CTAB method was without protein and RNA pollution. The results of agarose gel electrophoresis showed that electrophoresis of genomic DNA obtained through the two methods both had the main belt. However, genomic DNA extracted through improved SDS method degraded more than improved CTAB method. Conclusion Improved CTAB method can obtain relatively high quality genomic DNA of Cordia dicholoma seeds.

Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.

Objective To investigate the characteristics of central cord syndrome without fracture or dislocation and assess the effect of surgical management.Methods Twenty-one cases of central cord syndrome without fracture or dislocation were diagnosed with X-ray radiography,CT and MRI and treated surgically.Spinal cord dysfunction and its recovery rate were evaluated using American Spinal Injury Association (ASIA) system.Radiological and clinical evaluation was performed for all cases.Pre-and postoperative ASIA scale and score were statistically analyzed.Results All cases sustained cervical spinal cord compression resulting from cervical disc herniation in 18 cases,of which five were accompanied by ligamentum flavum hypertrophy and reductus,developmental cervical spinal canal stenosis in two cases and posterior longitudinal ligament ossification in one case.Neurological dysfunction involved in the upper extremity in 15 cases and upper and lower extremity in six cases.Mean period of follow-up was 13.5months.ASIA scale was improved from C (n =9) and D (n =12) before operation to C (n =1),D (n =6) and E (n =14) in the last follow-up.ASIA score of motor and sensory dysfunction revealed a (84.3 ±12.5)％ and (62.7 ± 14.6)％ improvements,with significant difference as compared with the preoperative one (P ＜ 0.05).Conclusions Cervical disc herniation is the major factor of spinal cord compression in central cord syndrome without fracture and dislocation.Neurological dysfunction occurs mostly in the upper extremity.Surgery is an effective method to release spinal cord compression and restore neurological function.
