Objective Rheological properties and gelation properties of agar were investigated. Methods The gelling point,melting point and the gel strength of agar were detected with MCR101 rheometer and TA texture testing instrument. Results and Conclusion Rheological properties of agar were affected by its concentration ,temperature and the addition of salt (such as NaCl ,CaCl2) and sucrose. Apparent viscosity exhibited shear thinning behavior following the power law model. Apparent viscosity increased with the increase of concentration,and decreased with the rise of temperature. The decrease in viscosity followed an Arrhenius temperature dependence. Agar solutions exhibited typical "weak gel" properties by small strain oscillatory measurements. The results indicated that the agar solution was characterized as a gel properties ,and which could form a kind of heat reversible gel. The gelling point of agar was lower than its melting point. The gel strength of agar could be affected by its gel time,and the addition of salt (such as NaCl,CaCl2) and sucrose.

By using the method of philology, 65 Hui prescriptions for treating cough were been collected to compare Arabic and Chinese names of pennisetum, anemarrhenae, honey, pease, white mustard, perilla and towel gourd stem. The Countif function in Microsoft Excel 2007 was used to count frequency of drugs in the prescriptions and summarize eight common Hui medicine for treating cough, namely sugar, honey, almond, fritillaria, liquorice, orange peel, white mulberry root-bark and lily. According to the commonly used drugs, philological studies and theories of Hui medicines, pathology and therapy of Hui medicines for treating cough were preliminarily inferred. In this study, 35 practical prescriptions and 30 simple and convenient Halal dietary prescriptions were summarized from collected prescriptions according to relevant literatures. On the basis of the long-lasting unique dietary therapy culture developed for Hui people, the simple and practical dietary prescriptions were defined according indications, therapy, prescription name and composition, and eight types of drug-admixed foods were summarized to relieve pains and improve health awareness and quality of life. Meanwhile, this study could also enrich and perfect the prescriptions, provide new ideas for improving health of patients, and lay a certain realistic foundation for further study of Hui medicines.

ObjectiveTo investigate the mechanism and the protective effect of heat shock protein 27 (HSP27) on rat cardiomyocytes when ischemic preconditioning performed.MethodsCultured rat cardiomyocytes were divided into four groups: control group, ischemic group,ischemic preconditioning group and cyclohexamide group. Cell viabilities were analyzed by MTT. The apoptosis was evaluated with DNA ladder and flow cytometry Annexin V Flous staining. Western Blot was used to determine the expression of HSP27 and caspase-3 in cardiomyocytes.ResultsIschemic preconditioning could improve cell viability. The apoptosis ratio in ischemic preconditioning group was significantly less than that in ischemic group. These were accompanied by an increase in the expression of HSP27 and a decrease in caspase-3. The expression of the increased HSP27 and the protective effect induced by ischemic preconditioning were completely abolished by the presence of cycloheximide, a translation inhibitor.ConclusionThe expression of HSP27 induced by ischemic preconditioning plays an important role in protecting cardiomyocytes, and the mechanism is possibly related to the inhibition of cell apoptosis.

Objective To investigate the effect of edaravone on the JAK2/STAT3 signaling pathway after ischemia-reperfusion injury in donor rat liver under different cold ischemia times. Methods A total of 102 SD rats were randomly divided into sham operation group,control group and experimental group. Six rats were in sham operation group with free liver operation and no transplantation. Forty-eight rats were in control group and experimental group respectively, and divided into subgroups according to the different cold ischemia times (30 min, 6 h, 12 h and 18 h). There were 6 donors and 6 recipients in each group. The rat model of orthotopic liver transplantation was established by modifiedtwo cuff method. All the donors were perfused by abdominal aorta and the warm ischemia time was 3-5 min. After different cold ischemia times, the experimental group was treated with edaravone (3 mg/kg) at 5 min before the opening of the new hepatic artery, and control group was injected with 3 mg/kg saline. Recipients of each group were sacrificed after 6 h. Finally, real-time fluorescence quantitative PCR was used to analyze the relative expression of JAK2/STAT3 mRNA of donor liver. Results The GAPDH gene and JAK2/STAT3 were well amplified. Under the same cold ischemia time, compared with the control group, the relative expression of JAK2/STAT3 was significantly decreased in the experimental group (P<0.05). With the prolongation of cold ischemia time, the relative expressions of JAK2 and STAT3 mRNA showed a decreasing trend in control group and experimental group, while the relative expression of JAK2 mRNA increased first and then decreased in the experimental group (P<0.05). Conclusion Edaravone has a protective effect on transplanted donor liver during different cold ischemia times, and extends the cold ischemia time for 18 h, which may be related to the inhibition of JAK2/STAT3 signal transduction pathway.

BACKGROUND: Non-invasive vascular ultrasound is used to assess in tima-media thickness (IMT) and atheromatous plaque, of which the result is better correlated to that of pathological examination. OBJECTIVE: Non-invasive vascular ultrasound was used to assess the hemodynamical changes of external and internal carotid in hypertensive elders, so as to investigate the relationship between pulse pressures, left ventricular mass index (LVMI), vascular resistance index (VRI) and shearing ratio. DESIGN: Randomized, controlled, correlative analyzedstudy. SETTING: Ultrasound Department of Affiliated Hospital of Jiangshu University. PARTICIPANTS: Totally 54 hypertensive elders, including 33 males and 21 females, were recruited from the Ultrasound Department of Affiliated Hospital of Jiangshu University, from September 30th 2000 to March 30th 2002. Meanwhile 26 normotensive elders (systolic pressure < 130 mm Hg and/or diastolic pressure < 85 mm Hg), including 16 males and 10 females, were selected as controls, METHODS: Color duplex blood flow imaging technique was used to assess the left ventricular end-diastolic diameter (LVEDD) and the interventricular septum thickness (IVST), so as to calculate the LVMI. The insiddiameter of bilateral common carotid artery (CCA) and internal carotid,IMT, the systolic peak flow velocity and resistance index were measured in order to calculate the vascular shearing ratio and atheromatous plaque index,moreover arterial pressure, LVMI, as well as resistance index and shearing ratio were subjected to linear correlative analysis,of which the results were compared with that of control group. MAIN OUTCOME MEASURES: ① Pulse pressure, LVMI and atheromatous plaque index of CCA. ② The inside diameter of bilateral CCA and internal carotid, IMT and the systolic peak flow velocity and resistance index were measured in order to calculate the atheromatous plaque index and maximum vascular shearing ratio. RESULTS: According to the experimental objective,data of all 80 cases were analyzed without loss. ① The pulse pressure and LVMI, the incidence of atheromatous plaque and plaque index of CCA in hypertensive elder group were obviously higher than that of control group [(64.36±7.44) mm Hg,(45.78±8.72) mm Hg; (131.47±18.73) g/m2, (83.28±12.34) g/m2; 5.62 ±1.78,3.44±1.10; 66.7%, 23.1%, (x2=13.37, t=5.730-13.234, P < 0.01)]. ② The inside diameter of bilateral CCA and internal carotid, IMT and resistance index in hypertensive elders were significantly higher than that of control group [CCA: (8.96±1.20) mm, (8.08±0.96) mm; (1.28±0.88) mm, (0.91±0.17) mm;0.75±0.05, 0.69±0.06; ICA: (6.82±1.12) mm, (5.72±0.92) mm; (1.06±0.17) mm,(0.76±0.15) mm; 0.70±0.07, 0.64±0.06, t=2.872-10.850, P < 0.01], but the systolic peak flow velocity and shearing ratio were markedly lower than that of control group [CCA: (47.44±12.85) cm/s, (60.20±14.32) cm/s;(225.78 ±95.76)/s, (300.26 ±110.42)/s. ICA: (41.22 ±10.18) cm/s,(48.64±11.58) cm/s; (268.54±112.56)/s, (324.52±121.42)/s, t=2.872-10.850, P < 0.01]. ③ The pulse pressure, LVMI, the resistance index of CCA and ICA and shearing ratio were linearly correlated (r=0.30-0.36, P < 0.05). CONCLUSION: Pulse pressure and LVMI were found increased in hypertensive elders, together with carotid vessels dilated, IMT and resistance index increased, as well as shearing ratio decreased, atheromatous plaque formed, vascular stiffness increased, which resulted in consequently decrease of vascular compliance.
