BACKGROUND: High blood lipid can cause a series of cardiovascular and cerebrovascular disease, which has been commonly accepted.OBJECTIVE: To probe into the rule of changes of blood lipid of the elders in aging process.DESIGN: Cross section survey.SETTING: Department of Nutrition, Shanghai Huadong Hospital. PARTICIPANTS: Totally 605 employees who took part in body examination and participated this experiment voluntarily from July 2000 to August 2004, were recruited, including 541 males and 64 females, 91 patients ＜ 70 years , 514 ≥ 70 years, 271 patients having the history of coronary heart disease, 83 of malignant tumors, and 251 of other diseases.METHODS: Blood lipid level of totally 605 who accepted physical examination was detected, at the same times, the disease history and common physical examination status were inquired. Venous blood of the patients was drawn after fasting over 12 hours, separating serum on the morning of the same day. Total cholesterol and triacylglycerol of the blood were detected with enzyme assay by using Automated Biochemistry Analyzer. Total cholesterol: 3.6-6.5 mmol/L; triglyceride: 0.4-1.8 mmol/L were considered as normal level, Total cholesterol: ＞ 5.72 mmol/L;Triglyceride: ＞1.72 mmol/L were considered as abnormal criteria.MAIN OUTCOME MEASURES: Comparison of the blood lipid index of the subjects of different age, disease type and gender RESULTS: Totally 605 elders were involved and all data of them was enthe blood lipid index of the subjects of different age: Peak of total cholesterol appeared at 70 to 74 years, then decreases gradually, the total cholesterol level of the subjects of 70 to 74 years was significantly higher than that at other age (P ＜ 0.05). While Triglyceride level had the trend of going up with growing older, except that of 75-79 ages group slightly went eases: The level of total cholesterol and triglyceride of the subjects in the malignant tumor group was lower than that of other disease groups, level of triglyceride of the subjects in the coronary heart disease was higher than detection rate of blood lipid of the subjects: Detection rate of total cholesterol was 15.5%, while that of triglyceride was 35.9%. There was no significant difference of the detection rate between male and female subjects (P ＞ 0.05).CONCLUSION: Change of blood lipid metabolism of elder with aging is related to the hormone change of different genders and disease types.

Objective:To investigate the effects of slowly release(SR) carbohydrate system on glucose and lipide metabolism in the elder patients with type 2 diabetes. Methods:The previous enteral nutrition was replaced totally or partially with Glucerna in 11 cases of elder patients with type 2 diabetes for 1-3 months.The changes in hemoglobin, lymphocyte counts, serum albumin, total protein, glycemia, postprandial 2 hours blood glucose,glycosylated hemoglobin, triglyceride, cholesterol, kidney function,electrolytes and the symptoms of gastrointestinal tract were observed. Result:Total protein(P

Objective:To compare the nutritional status of inpatients after enteral nutrition (EN) and parenteral nutrition (PN). Method: A multi-center survey of 1 142 inpatients from the Department of gastrointestinal surgery, thoracic surgery, gastroenterology, respiratory disease, neurology, neurosurgery and the intensive care unit of 6 general hospitals in Beijing and Shanghai was adopted in this study. Body weight (BW), haemoglobin (Hb) and serum albumin (sALB) were compared before and after EN or PN respectively. Results: BW, Hb and sALB all decreased after the nutritional support both in EN and PN groups, but only significantly in BW and sALB (BW: -1.58?2.36 kg/m2 vs -2.09?2.66 kg/m2, P

Objective:To investigate the effect of vitamin E, selenium and quercetin on the expression of zf-9 mRNA of hepatic stellate cells (HSC) during early acute liver injury in rats. Methods:90 healthy SD rats were randomly divided into four groups: normal control, pathological control, VE 20 mg/(kg bw﹒d) + Se 16 ?g/(kgbw﹒d) supplement, and quercetin 50 mg/(kg bw﹒d) supplement through intragastric way for 15 d respectively. The normal control group was injected with normal saline, the others were given intraperitonal CCl4 once to induce acute liver injury model. The serum levels of MDA, SOD, ALT and AST were determined at 3 h, 6 h, 12 h and 24 h after CCl4 injection respectively. The pronase-collagenase perfusion of liver was used to isolate HSC, and the expression of zf-9 mRNA was examined by RT-PCR. Results: Serum levels of MDA were lower in VE+Se supplement group and quercetin supplement group than pathological group. Supplementation with VE+Se and quercetin could decrease the level of ALT and AST and down-regulate the expression of zf-9 mRNA. Conclusion:Dietary supplementation of VE,Se and quercetin could effectively down-regulate the expression of zf-9 mRNA in HSC during early acute liver injury in rats.

Objective: To measure the glycemic index of foods contained low carbohydratesand discuss the relationship between glycemic index and the amount of fat, carbohydrate, protein and diet fiber from these foods. Methods: According to the method of Wolver,the GIs of these kinds of foods had been determined and caculated by using 25 gram carbohydrates as control because of the low percent(10%)of carbohydrates in foods. Results: The results of GI in 13 kinds of the foods were worked out and there was negative correlation between diet fiber and GI. Conclusions: The inference factors of GI are not the kinds of carbohydrate but the amount of diet fiber in these foods.

Objective: To apply the NRS2002 to screen the nutritional status of preoperative patients and investigate the nutrition support in the perioperation and clinical outcomes. Methods: 127 selective operational cases(including general surgery,thoracic surgery,gynecology and orthopedic) were recruited to adopte the NRS2002 which issued by CESPN in 2006,and the nutrition support,energy and nutriment in the perioperation,complications,length of stay and drug costs were investigated. Result: 30.7% patients needed nutrition support,with general surgery(28.3%) being higher than thoracic surgery(2.4 %),gynecology(0%) and orthopedic(0%).The nutritional risk in elderly,carcinoma,abdominal operation patients were 18.1%,19.7% and 18.1% seperately,which was higher than others(P

OBJECTIVE:To observe the effects and side effects of recombinant erytropoietin(rEPO)on patients with anemia in chronic renal failure(CRF).METHODS:128 patients with anemia in CRF had been given rEPO by subcutaneous injection for12weeks,the clinical effects were observed by own control method.RESULTS:Excellence cases amounted 91,efficacy cases33,and the overall efficacy rate was96.88%;The side effects included hypertension,coagulation in dialysis machine,pain in injection site and head,no severe adverse drug reactions were found;No degradation in renal function was found in non-dialysis patients during the medication.CONCLUSIONS:rEPO could improve anemia in CRF safely and effectively.

Objective To study current status of health education and explore its pattern in community health-care service(CHS)in Shanghai.Methods A total of 200 health-care workers(HCWs)from five CHS centers in Shanghai were investigated by questionnaire of health education knowledge.Results Among 200 HCWs investigated,96.5%(193/200)of them have recognized importance of health education,98.0%(196/200)could undertake health education in their clinical work,only 60.5%(121/200)had receired regular training on it,and 85.5%(171/200)thought they should be further trained regularly.Correct awareness of knowledge was 94.O%.47.0%and 33.6%for health education perception,healthy life-style and health education knowledge for chronic disease.respectively in them.There was very significant difference in correct awareness of knowledge between HCWs with varied ages and districts(χ2=17.663 and 82.376,P=0.001 and 0.000,respectively),but no significant difierence was found between men and women and those with varied professional titles(χ2=0.015 and 2.406,P=0.903 and 0.300.respectively).Short of time(48.5%),lack of relevant knowledge(15.0%)in HCWs and poor compliance of patients(33.0%)were main factors influencing their implementation of health education.Conclusions HCWs in CHS have already recognized importance of health education.but have not known enough its theoretical knowledge and skills.It is necessary to set guidelines of health education intervention for HCWs in CHS,and perfect monitoring and evaluation.as well as mechanism for rewards and penalties to promote development of health education in CHS.

Objective To investigate the status of appendicular skeletal muscle mass,muscular strength and changes of muscle function in the elderly in Shanghai.Methods A total of 402 participants were recruited from physical examination centers in our hospital.Appendicular skeletal muscle mass (ASM) was measured by bioelectrical impedance analysis (BtA).The ASM index (ASM/height2) was calculated.Muscle function was measured by testing gait speed (m/s).Muscle strength was measured by handgrip strength (HGS) using an electronic hand dynamometer.Results The ASM index significantly declined with age in both men and women (F＝2.133 and 3.124,both P＝0.000).For women,there was a significant difference in HGS only between the youngest age group (aged 60～69 years) and the oldest age group (aged≥80 years)(P＝0.005).For men,HGS was significantly different among all age groups (all P＜0.05).There was no significant difference in gait speed between 60-69 years group and 70-79 years group in both genders (both P＞0.05),while the significant differences in gait speed were observed between the 70-79 years old groups and ≥80year old group in both genders (both P＜0.05).Conclusions Appendicular skeletal muscle mass,strength and function are decreased with ageing in the elderly.The muscle strength decreases faster in the elderly man than in the elderly woman,and muscle function decreases significantly in both genders after 80 years old.
