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 detect the opening of the myocardial mitochondrial permeability transition pores (MPTP) after intrauterine asphyxia in neonatal rats,and to explore the mechanism of the myocardial hypoxic-ischemic and reperfusion injury caused by the opening of MPTP after asphyxia.Methods Cesarean sections were undertaken in female SD rats at the 21st day after pregnancy.The uterine arteries were clamped for 30 minutes followed by releasing for 1 hour and the pups were allocated into the asphyxia group.The uterine arteries were isolated but not clamped and the pups were allocated into the control group.There were 30 neonatal rats in either group and all of them were sacrificed 24 h after birth.Serum cardiac troponin Ⅰ (cTn Ⅰ) levels were detected by enzyme linked immunosorbent assay.The opening degree of MPTP was detected by fluorospectro-photometry.Myocardial ischemic areas were detected by TTC staining.Tissues from the cardiac apex were taken and the pathologic changes of the myocardium were explored by hematoxylin-eosin staining.SPSS for Windows 13.0 was used for statistic analyses.Results In HE staining slices,the myocardial cells in asphyxia group were disarranged and edematous.In control and asphyxia group,the serum cTn Ⅰ levels were (0.08 ±0.04) μg/L and (0.40 ±0.29) μg/L (P ＜0.01),the myocardial ischemic areas were (8.01 ±3.48) ％ and (42.50 ± 15.90)％ (P ＜0.01),and the opening degrees of MPTP were (118.10 ± 19.10) RFU and (79.40 ± 10.57) RFU (P ＜ 0.01) respectively.The serum levels of cTn Ⅰ,the myocardial ischemic areas,and the opening degrees of MPTP were significantly increased in asphyxia group compared with control group.The serum level of cTn Ⅰ was positive correlated with the opening degree of MPTP in either group(r =-0.384,P ＜ 0.01).Conclusion There are myocardial injuries in neonatal rats after asphyxia,which represent as high level of serum cTn Ⅰ,myocardial ischemia and necrosis.Opening of the myocardial MPTP is one of the causes of myocardial injury.

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 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 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 study the application of extracellular laccase from endophytic fungi to total flavonoid extraction. Methods The extracellular laccase vitality of an endophytic Fusarium sp.C-8 from Artemisa annua reached 36.1 U/mL when the fungus was cultivated in revised PDA medium with initial pH 7.0 at 20℃ on a rotary shaker incubator for 6 d. The crude laccase from the cultural medium was applied for extraction of flavonoid from the buds of Sophara japonica. The optimization on the ratio of dry buds to crude enzyme liquid,temperature,time,and pH value was carried out during the process of laccase-assistant treatment. Results After incubation with 40∶1 of crude enzyme (pH 7.0) at 20℃ to dry buds for 1 h,the extraction rate of total flavonoids was 11.4 %,a more increase of 28.7 % than that in regular extraction process. Conclusion The results present a practical method of laccase-assistant extraction process on total flavones in S. japonica buds.

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.
