Objective: To establish an echocardiography parameter scoring system for assessing the risk of 1 year re-admission in patients with left ventricular systolic dysfunction (LVSD). Methods: A total of 412 chronic LVSD patients treated in our hospital from 2007-01 to 2016-01 were studied and the end point event was 1 year re-admission. The data included in 280 patients from 2007-01 to 2014-12 for establishing the scoring system and 132 patients from 2015-01 to 2016-01 for verifying the system. Based on 7 echocardiography parameters, the patients were divided into 7 sets of groups: ① Left ventricular diameter (LVD): Group0, n=290 and Group1, n=122;② Mitrial regurgitation (MR): Group0, n=203, Group1, n=138 and Group2, n=71; ③ Tricuspid regurgitation (TR): Group0, n=302, Group1, n=90 and Group2, n=20; ④ LVEF: Group0, n=272 and Group1, n=140; ⑤ Pulmonary artery systolic pressure: Group0, n=282 and Group1, n=130; ⑥ Hydropericardium: Group0, n=347 and Group1, n=65; ⑦ Hydrothorax:Group 0, n=261, Group1, n=86 and Group2, n=65. The parameters were identified by COX regression analysis, weighted value of scoring system was calculate by hazard ratio (HR), predictive value for1 year re-admission was assess by ROC curve and finally, scoring integration was verified by validation data group. Results: The integration score was calculated as follows: LVD>60mm=1 point; TR: Group1=1 point and Group2=3 points; MR: Group1=2 points and Group2=4 points; Hydrothorax: Group1=2 points and Group2=3 points;Hydropericardium=1 point. COX regression analysis indicated that for 1 year re-admission: HR=1.552 in Group1 vs Group0, HR=3.374 in Group2 vs Group0 and HR=4.562 in Group3 vs Group0, all P<0.05. The AUC of ROC for establishing the data was 70.0% (95% CI 0.640-0.761) and for verifying the data was 70.4% (95% CI 0.616-0.792); the best integration score was 4 points. Conclusion: Echocardiography parameter scoring system may better predict the risk of 1 year re-admission in LVSD patients which is superior to single echocardiography parameter.

OBJECTIVETo investigate the effect of preventive moxibustion at the acupoint of 'Guanyuan" (CV 4) on the stress-related hormones, proteins and genes in natural menopausal rats, and explore its protective mechanism.

METHODSOne hundred and twenty eight healthy female SD rats were used in this study, in which 16 rats aged 4 months were used as normal control group, the rest 10-month-old rats with disorder of estrus cycle were randomly divided into 7 groups, including 4 control groups at the age of 10, 12, 14 and 16 months, and 3 preventive moxibustion groups at the age of 12, 14 and 16 months, 16 cases in each group. The 10-month-old rats were treated with preventive moxibustion at the acupoint of "Guanyuan" (CV 4), twice a week for 8 weeks consistently, then observed on the following 12, 14 and 16 months. Its effects on the level of heat shock protein 70 (HSP 70), heat shock protein 70 mRNA (HSP 70 mRNA), corticotropin-releasing hormone (CRH), beta-endorphin (beta-EP), adrenocorticotrophic hormone (ACTH) in the different nuclei of hypothalamus were examined with radio-immunity, immunohistochemistry or in situ hybridization methods.

RESULTSIn the control groups, the expression of HSP 70 and HSP 70 mRNA was increased in paraventricular, arcuate and supraoptic nucleus, the level of CRH, beta-EP was showed with declining trend in volatility, while the content of ACTH was increased. In comparison to the same-aged control groups, the preventive moxibustion groups were showed that the expression of HSP 70 in the 14-month-old group was lower and the expression of HSP 70 mRNA in the 12 and 16-month-old group was significantly higher in the paraventricular nucleus (all P < 0.05), the expression of HSP 70 in the 12 and 14-month-old groups and HSP 70 mRNA in the 12-month-old group was significantly increased in the arcuate nucleus (P < 0.05, P < 0.01), while the expression of HSP 70 in the 14-month-old group and HSP 70 mRNA in the 12 and 16-month-old group was significantly decreased in the supraoptic nucleus (all P < 0.05), the content of CRH and ACTH decreased significantly in 14-month group (P < 0.05, P < 0.01), but the content of beta-EP obviously went up in the 12-month-old group (P < 0.05).

CONCLUSIONPreventive moxibustion at the acupoint of "Guanyuan" (CV 4) can regulate the expression of stress proteins, genes and hormones in the hypothalamus for the natural menopausal rats, which might be playing a protective role.

OBJECTIVETo describe the prevalence of body overweight and obesity and its changes among Chinese people during 1992-2002, and to provide scientific basis for developing intervention strategies for obesity in China.

METHODSThe data from "1992 China third National Nutrition Survey" (78,704 subjects, 38,323 male and 40,381 female) and from "2002 China National Nutrition and Health Survey" (209,849 subjects, 101,377 male and 108,472 female) were used in this study. The overweight and obesity were defined by using WHO Z-score criteria for children younger than 7 years old, Chinese age-, sex-specific BMI criteria for children aged 7-17 years, and Chinese BMI criteria for adults.

RESULTSThe overall prevalence of overweight and obesity of Chinese people was increased by 38.6% and 80.6%, respectively during the period of 1992-2002. The prevalence of overweight and obesity of Chinese people aged 0-6 years, 7-17 years, 18-44 years, 45-59 years and above 60 years was increased 31.7%, 17.9%, 66.7%, 45.2% and 43.7%, respectively. The increase of the prevalence of overweight and obesity was higher in girls younger than 6 years than their male counterparts, while among other age groups, that were higher in boys than girls. The prevalence of overweight and obesity among people living in rural areas was lower than that of their urban counterparts, while the increment of overweight and obesity prevalence among rural people was greater than that of their urban counterparts. It was estimated that another 70 million overweight and 30 million obese Chinese people emerged in China from 1992 to 2002.

CONCLUSIONThe prevalence of overweight and obesity of Chinese people was increased rapidly in the past decade, which had affected 260 million Chinese people. It would continue to increase in the near future if effective intervention measures have not been taken.

OBJECTIVETo investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population.

METHODSPlasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey (CNHS) in 2002 which involved 14 252 participants at the age of 18 years or older.

RESULTSThe mean levels of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) in the participants were 3.81 mmol/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L, respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L, respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females. Dyslipidemia prevalence was higher in urban districts than in rural areas (21.0% vs. 17.7%). The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants.

CONCLUSIONDyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.

OBJECTIVETo explore the mechanism of "preventive acupuncture and moxibustion" for regulating hypothalamic function in ovariectomy rats.

METHODSThirty female SD rats, aged 3.5 months, were randomly divided into normal group, sham operation group, ovariectomy model group, preventive acupuncture group and preventive moxibustion group. After "preventive acupuncture and moxibustion" were previously given to the preventive acupuncture group and the preventive moxibustion group for one month, respectively. At the same time, ovarietomy was made in the preventive acupuncture group, the preventive moxibustion group and the ovariectomy model group. For the sham operation group, only a little fat around the ovary was removed without ovariectomy, and nothing was not applied to the normal group. Immunohistochemical and in situs hybridization methods were used to investigate changes of expressions of ER-alpha and ER-alpha mRNA in paraventricular nucleus, supraoptic nucleus and arcuate nucleus.

RESULTSIn the model group the expressions of ER-alpha and ER-alpha mRNA in paraventricular nucleus and the expression of ER-alpha mRNA in supraoptic nucleus increased significantly (P<0.01), but the expression of ER-alpha dropped significantly in both supraoptic nucleus and arcuate nucleus (P<0.01). After preconditioning with acupuncture or moxibustion, the expression of ER-alpha mRNA in paraventricular nucleus significantly reduced (P<0.05), and the expression of ER-alpha had no significant change (P>0.05); the expression of ER-alpha in supraoptic nucleus and arcuate nucleus significantly increased (P<0.01 or P<0.05), and the expression of ER-alpha mRNA in paraventricular nucleus had no significant change (P>0.05).

CONCLUSION"Preventive acupuncture and moxibustion" at "Guanyuan" (CV 4) have an effect on the expressions of ER-alpha and ER-alpha mRNA in different hypothalamic nuclei in ovariectomy rats, which possibly is one of the ways for modulating the hypothalamic activity.

OBJECTIVETo study the difference in prevalence of dyslipidemia, hypercholesterolemia, hypertriglyceridemia and low blood high-density lipoprotein cholesterol (HDL-C) between the residents of urban and rural areas of varied regions in China.

METHODSFasting plasma levels of total cholesterol, triglyceride and HDL-C were determined with the enzyme methods for 49,252 subjects aged 18 and over during August to December, 2002.

RESULTSPrevalence of dyslipidemia in Chinese adults aged 18 and over was 18.6%, with 17.0%, 22.9% and 23.4% in the groups of 18-44, 45-59 and over 60 years old, respectively, 22.2% and 15.9% in males and females, respectively, and 21.0% and 17.7% in urban and rural areas, respectively. Prevalence of hypercholesterolemia, hypertriglyceridemia and low blood HDL-C in those aged 18 and over was 2.9%, 11.9% and 7.4%, respectively.

CONCLUSIONSDyslipidemia has become one of important risk factors threatening health of Chinese people, with hypertriglyceridemia and low blood HDL-C as two major types in those aged 18 and over. Prevalence of dyslipidemia was nearly the same in the middle-aged and in the elderly people, and not significantly different in those living in urban areas from those in rural areas. It is very important to pay more attention to earlier comprehensive prevention and control of dyslipidemia.

Objective A cross-sectional study was carried out to observe the prevalence.Incidence and risk factors of deep venous thrombosis(DVT)in patients from intensive care unit(ICU).Methods Patients who were admitted to respiratory intensive care unit(RICU)and emergency intensive care unit (EICU)of Beijing Chaoyang Hospital and Bering Anzhen Hospital were screened in our studv.All patients enrolled underwent compression ultrasonography(CUS)witlain 48 h upon their admission to the ICUs.CUS Was re-performed at 10-14 day,or when 1eaving ICU or at the time patients developed signs and symptoms(pain,heat,redmess,edema)of DVT.Risk factors which were presumed assiated with DVT were recorded.The main identified outcome Was the presence of DVT.The secondary outcome Was pulmonary thromboembolism(FrrE).Results DVT was found in 30 patients of 252 patients within 48h (11.90％).One hundred seventy-two patients were perforrned CUS two times or more.26 patients(15.12％)had DVT.D-dimer,history of operation,kidney failure appeared to be independent risk factors for DVT in ICU patients.13 patients were suspected PTE and 3 patients diagnosed as PTE.Conclusion ICU doctors should pay more attention to DVT,which is relatively common in ICU patients.

OBJECTIVE: To determine the therapeutic status and rate of reaching target blood pressure in elderly isolated systolic hypertension (EISH) patients who were hospitalized and to discuss the rationality of the drug therapy. METHODS: Three hundred and fifty-seven EISH inpatients were investigated retrospectively. The frequencies of using antihypertensive drugs and the strategy of drug therapy programs were calculated. The drug efficacies were assessed among various drug therapy groups. RESULTS: The frequencies of using antihypertensive medicine categories were calcium channel blocker (CCB) 64. 15%, angiotensin-converting enzyme inhibitor (ACEI) 32.77%, diuretics 26.33%, beta-blocker (BB) 25.77%, angiotensin receptor blocker (ARB) 23.81%, and alpha-blocker 4.20%, respectively. Among the 357 cases 42.86% were treated with monotherapy while 57.14% with combined therapy. Among the combination therapy groups, the diuretic-based multiple therapy occupied 16.53%, and the non-diuretic-based multiple therapy held 40.62%. The systolic blood pressure control rate was 67.79%. The rate of diastolic blood pressure < or = 70 mmHg was 26.89%, 8 cases of them occurred myocardial ischemia. CONCLUSION How to select the optimal antihypertensive drug therapy for EISH patients is important in achieving the blood pressure goal. While thinking over intervention at lower blood pressure levels to achieve target goals, physicians should prevent from excessively lowering the diastolic blood pressure.

This study is to investigate the protective effects of the SB203580 against radiation induced mortality and intestinal injury of mice. A total of 67 male C57BL/6 mice (20.0-22.0 g) were matched according to body weight and randomly assigned to one of three groups: control, total body irradiation exposure (IR, 7.2 Gy) only, and IR (7.2 Gy) + SB203580 (15 mg x kg(-1)). 30 days survival rate was observed in the experiment. In intestinal injury experiment, the expression levels of caspase-3, Ki67, p53 and p-p38 were assayed in the mice intestine crypts. The results showed that the 30 days survival rate was 100% (control), 0 (IR) and 40% (IR+ SB203580), separately. Compared to the IR groups, the positive cells of caspase-3, p53 and p-p38 in crypt cells decreased 33.00%, 21.78% and 34.63%, respectively. The rate of positive cells of Ki67 increased 37.96%. Significant difference was found between all of them (P < 0.01). SB203580 potently protected against radiation-induced lethal and intestinal injury in mice, and it may be a potential radio protector.
