Objective To understand the relationship between age and chronic complications in hospitalized aged patients with hypertension, to provide evidence for hypertension prevention and control. Methods To retrospectively analyze the clinical and laboratory data on 17,682 patients with essential hypertension during Jan 1st,1993-Dee 12th, 2008 in PLA general hospital. Results 1)Among all of the inrolled cases, those aged 60-64 account for 27.87%, 65-69 years group account for 26.55%, 70-74 years group accounted for 23.96%, 75-79 years group accounted for 14.14%, 80-84 years group accounted for 5.26%, 85-89 years group accounted for 1.69%, > 90 years accounted for 0.41%. 2) The prevalence rate of chronic complications in 60-69 years group were 31.3-31.2% for diabetes and,22.6-27.0% for cerebrovascular disease, 9.5-11.1% for myocardial infarction, 6.7-9.1% for heart failure, 5.8-6.0% for renal dysfanction 4.9-6.8% for atrial fibrillation, 0.1-0.3% for multiple organ dysfunction syndrome (MODS) in the elderly(P <0.05 ). 3) The first four complications of hypertension were diabetes(33.5%), cerebrovascular disease (31.9%), myocardial infarction(13.2%) and heart failure(12.3%) in 70-74 years group (P<0.05), cerebrovascular disease (42.8%), diabetes (32.8%), heart failure (16.5%) and myocardial infarction(15.9%) in 75-79 years group (P<0.05), cerebrovascular disease (45.4%), diabetes (35.0%), heart failure (21.1%) and myocardial infarction(15.9%) in 80-84 years group (P<0.05), cerebrovascular disease(42.5%), diabetes (35.8%), heart failure (23.1%) and renal dysfanction (17.7%) in 85-89 years group(P<0.05 ),and cerebrovascular disease (45. 2%), heart failure(31.5%), diabetes (26.0%) and renal dysfanction (20.5%) in patients more than 90 years group (P<0.05). Conclusions The prevalence rate and kinds of chronic complications in hospitalized aged patients with hypertension were changed with the increasing age, and the first kind of complication is cerebrovascular disease. It is of more importance to prevent the occurrence of renal dysfanction and heart failure in those hypertension patients who were more than 80 years old.

OBJECTIVE To understand the status quo for hospital infection hospital infection to provide a scientific basis. METHODS A cross-sectional survey was taken combined with the hospital bedside investigation and records investigation. RESULTS In 1033 cases,the prevalence rate was 3.87%,and the infected sites were the respiratory site,superficial incision,skin and soft tissue. Utilization rate of anti-bacterial drugs was 60.31%,the pathagen detection rate before treatment was low only 7.73%. CONCLUSIONS Prevalence rate survey method is simple and reliable,it may be the basic reflect of hospital infection. Further strengthening the management of invasive operations,regulateing the rational use of antibiotics status quo,improving the detection rate of pathogens and reduceing preventive medication and antibiotic usage are all evitable.

Objective To investigate the accuracy of image registration with computed tomograpby (CT) and magnetic resonance imaging(MRI) and to determine gross tumor volume(GTV) of hepatocellular carcinoma(HCC).Methods Thirteen patients were enrolled in this study.CT image was taken in inhala tion phase,and MRIT2 image at the time of peak exhalation.Additional MRIT2 image was taken by fast scanning(MRIT2F) in peak inhalation phase in 6 patients.After mutual information method to CT/MRI im age registration,manual adjustment was made to optimize the accuracy of image fusion.The GTV and liver of each patient was independently contoured by two observers on CT,MRIT2 and MRIT2F images.The accura oy of image fusion was assessed by the ratio of liver overlap(P-LIVERCT-MRIAT2 ,P-LIVERCT-MRIT2F) ,and the dis tance between bone markers(DCT-MRIT2,DCT-MRIT2F) of CT and MRI on the fused image.The volumes of GTV contoured on CT (V-GTVCT),MRIT2 (V-GTVMRIT2),MRIT2F (V-GTVMRIT2F) and their overlap (V GTVCT-MRIT2,V-GTVCT-MRIT2F) and composite volumes (V-GTVCT+MRIT2,V-GTVCT+MRIT2F)were measured.The percentage of V-GTVCT and V-GTVMRIT2 on V-GTVCT+MRIT2,V-GTVCT and V-GTVMRIT2F on V-GTVCT+MRIT2F,V GTVCTMRIT2 and V-GTVCT-MRIT2F on V-GTVCT was also calculated,respectively.Results The mean DCT-MRIT2 and DCT-MRIT2F were 2.7±0.8 mm and 2.1Q±0.9mm.The mean P-LIVERCT-MRIT2 and P-LIVERCT-MRIT2F were 85.9% ± 4.1% and 92.7%± 1.5%.Interobserver difference was significant for GIN defined by CT,but not by MRIT2.V-GTVCT,V-GTVMRIT2 and V-GTVMRIT2F were 387±396 cm3 ,488 ±461 cm3 and 597 ±541 cm3 ,respectively.The percentage of V-GTVCT and V-GTVMRIT2 on V-GTVCT+MRIT2 was 66.2%±13.5% and 88.7% ± 10.2% ,while V-GTVCT and V-GTVMRIT2F on V-GTVCT-MRIT2F was 71.3%±12.7% and 93.5%± 4.8%,respectively.Conclusions CT and MRI for image fusion should be obtained in the same respirato ry phase and in the same treatment position.Automatic registration using mutual information method by auto matic registration software is useful.CT and MRI image should be integrated for HCC GTV delineation.GTV used for planning should be the sum of CT-defined GTV and MRl-defined GTV.

Objective To evaluate the efficacy of percutaneous CT guided interstitial 125Ⅰ seeds implantation treatment for refractory pelvic malignant tumors and discuss the procedure of technique.Methods Twenty-three patients with refractory pelvic malignant tumors(25 lesions,diameter 3.5-7.0 cm,mean 4.5 cm) showing failure response to full chemotherapy and/or radical radiotherapy after tumors resection were undergone percutaneous CT guided intratumoral 125Ⅰseed implantation.Treatment plan system(TPS)was used to design the distribution and number of 125Ⅰ seeds according to matched peripheral dose(MPD)1-3 days before the procedure.Of which 6 cases received combined internal iliac arterial infusion chemotherapy before or after the 125Ⅰ seed implantation procedure.Results 9 ～ 75(mean 27)125Ⅰ seeds were implanted into a single tumor at first time including 6 patients with intraarterial chemotherapy for 14 cycles(mean 2.3 cycles),showed relief of clinical pain symptoms in 16 of 23 cases,72 h ～ 4 w after the seeds implantation;with the an effective rate of 69.6%.Follow up for 2-34 months(median,21 months),CT or MRI performed 2 months after the seeds implantation showed no CR,but PR in 18 cases,SD in 4 cases,and PD in 1 case,with overall response rate of 78%(18/23),and no serious complication.In addition,20 cases survived,with the longest one of 34 months and the other 3 died.Conclusions Intratumoral 125Ⅰ seeds implantation under CT guidance for pelvic refractory malignant tumors is safe,minimally invasive,and effective.

Objective To study the effect of assistive functional rehabilitation exercise on cardiac functioning of patients with chronic heart failure (CHF). Methods Sixty CHF patients were divided randomly into a treatment group (the rehabilitation group) and a control group, with 30 in each group. All the patients were administered routine therapy. In the treatment group, the patients were administered rehabilitation exercises with the assistance of a electric equipment made by the authors, daily for 5 days a week for a total of 3 months. The New York Heart Association (NYHA) cardiac function grading, the left ventricular ejection fraction(LVEF), the left ventricular end diastolic diameter (LVEDD) and the brain natriuretic peptide (BNP) level in plasma as well as the 6 min walking range were observed in both groups before and after treatment. Results After 3-months of treatment, the NYHA grading, LVEF, LVEDD, BNP level in plasma and 6 min walking range were all significantly improved in both groups when compared with those before the treatment, with the treatment group improved to a significantly larger extent than the control group ( p<0.05 ). Conclusion Assistive rehabilitation exercise in addition to the routine therapy can significantly help improve the cardiac function in CHF patients.

Objective To explore the mechanism and regulative function of betulin on anti-aging genes related of normol human dermal fibroblasts (ESF-1), and to reveal the repairing mechanism of betulin on wrinkles. Methods The cultured cell in vitro were divided into the control group, the estradiol group and the betulin high, medium and low dose groups. Competence of ESF-1 cells was detected by MTT. Expression of mRNA of collagen type I and Ⅲ (ColⅠand Col Ⅲ), tissue inhibitors of matrix metalloproteinase 1 and 2 (TIMP-1 and TIMP-2), matrix metalloproteinase 1 (MMP-1) was detected by RT-PCR. Results Compared with the control group, the proliferation of ESF-1 cells (0.455 ± 0.037, 0.445 ± 0.040 vs. 0.385 ± 0.601) in the estradiol group and the medial-dose betulin group were increased (P<0.05). Compared with the control group, the expression of mRNA of ColⅠ (0.960 ± 0.012, 0.929 ± 0.015 vs. 0.842 ± 0.014), Col Ⅲ (0.892 ± 0.009, 0.824 ± 0.022 vs. 0.768 ± 0.025), TIMP-1 (0.938 ± 0.026, 0.878 ± 0.035 vs. 0.796 ± 0.022), TIMP-2 (0.557 ± 0.025, 0.506 ± 0.036 vs. 0.436 ± 0.063) in the estradiol group and the medial-dose betulin group were increased (all P<0.01). Conclusion Betulin based on increasing the competence of ESF-1 cells, promoting collagen synthesis and the expression level of related-proteinase is to suspend the development of wrinkles.

AIM: To examine the effects of hydrogen peroxide on intracellular free calcium concentration([Ca~(2+)]i) in cardiomyocytes and its antagonism by taurine. METHODS: A cell culture model of neonatal rat cardiac myocytes was used. There were four groups, control group, hydrogen peroxide (H_2O_2) group, H_2O_2+taurine (simultaneously) group,and H_2O_2+taurine (in sequence) group. Confocal microscope was used with Fluo-3/AM as calcium indicator to detect changes of [Ca~(2+)]i immediately and 15 minutes after H_2O_2 intervention, respectively. RESULTS:The intracellular fluoresence intensity of singular cardiomyocyte in H_2O_2 group was significantly higher than the control group 15 minutes after intervention (P

Aim To establish depression rat model with kidney-yang deficiency and evaluate the related parameters.Methods A total of 24 adult SD rats were divided into control group,mod-el group and self-healing group by body weight.Model group and self-healing group were injected hydrocortisone for 21 days, meanwhile the control group was injected sodium chloride.After modeling,the related indexs detection were taken out:open-field test,sucrose preference test and forced swim test.Then the orbital blood was taken to detect 5-HT,DA and NE by LC-MS/MS.And liver,kidney,spleen,thymus,adrenal gland,testis and epididymis were taken to calculate organ index.Results Compared with the control group,model rats displayed depres-sion and kidney yang deficiency syndrome such as dry hairs, chills,back arched and so on. Correspondingly, the body weight increased slowly.Immobility in FST was significantly in-creased. Sucrose preference, horizontal scores and vertical scores was significantly decreased.Organ index decreased in liv-er,kidney,spleen,adrenal,testis and epididymis.The level of 5-HT and NE was significantly high.Compared with the model group,5-HT,NE and DA were significantly reduced,5-HT and DA were even lower than those of the control group.Conclusion Depression rat model with kidney-yang deficiency could be in-duced by continuous injection of hydrocortisone.
