Objectives To evaluate the influence of cardio-pulmonary bypass (CPB) to the endothelial function and lipid oxidative status of the Coronary Artery Bypass Grafting (CABG) patients. Methods Thirty-five coronary patients (female 5 cases, male 30 cases, mean age 59.5±8. 6 years) who needed CABG operation therapy were included. The control group consisted of 20 health volunteers (female 5 cases, male 15 cases, mean age 49. 5 ± 7.3 years).Blood samples were taken at preoperative, 3 and 7 days postoperative. Serum von Willebrand factor (vWF) level, one of the endothelial dysfunction markers,and oxidized low density lipid (OxLDL) level, one of the lipid oxidization status markers were detected with ELISA kits. Results The levels of vWF and OxLDL in CABG patients' serum were elevated significantly compared with those of control group ( 139.60% ± 34. 39% vs 82. 79% ±13. 89% and 63. 7 ±18. 9U/ml vs 25.4± 15.2U/ml respectively). Three and 7 days after CABG significant increases in the vWF level (194. 30% ±37. 74%; 181.07% ±31.05%vs 139.60% ±34.39% at baseline, P＜0. 0001, respectively) and OxLDL level (79. 3±26. 7U/ml; 72.4±23.1U/ml vs 63.7±18. 9U/ml at baseline, P＜0. 01, respectively) were detected. Conclusion Compared with normal people, the endothelial system of CABG patients is impaired, and their lipids are in a more oxidative status. CABG procedure with CPB can further deteriorate the conditions, which may imply that the patients are predisposed to acute coronary accident shortly are the procedure.

This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1). This paper developed a selective, accurate and sensitive HPLC-FLD method for the simultaneous determination of four anthraquiones in rat plasma.

Insulin resistance and insulin secretion deficiency are main machanisms in inducing type 2 diabetes mellitus (T2DM), and mitochondria damage plays an important role in them. Research shows that autophagy is a self-protective mechanism of cells, which plays an important role in maintaining the normal structure and function of pancreatic β cells and improving insulin resistance. Previous studies show that traditional Chinese medicine can regulate cell autophagy to influence β cells and insulin resistance, type 2 diabetes mellitus and its complications. Thus this review will talk about the process of the relationship between autophagy and T2DM and the intervention effect of traditional Chinese medicine.

Objective To investigate the effcts of cervical mild hypothermia auxiliary therapy on stress reaction in patients with cervical spinal cord injury. Methods 84 cases cervical spinal cord injury patients were randomly divided into two groups:a cervical mild hypothermia group (42 cases)and a routine treatment group (42 cases), 64 healthy men who come for health examination were recruited and served as healthy control. Routine treatment were used in both treatment groups, in edition, the LM-HAT was just applied in mild hypothermia group. The changes of the concentrations of corticotropin releasing hormone (CRH), adrenocorticotropin hormone (ACTH), corticosteroid (Cor), arginine vasopessin (AVP) in serum and the symptoms of the stress dsease(hypertension, high blood sugar)were observed before treatment and 1 week after treatment. Results The concentrations of CRH, ACTH, Cor, AVP in serum and the symptoms of stress disease in mild hypothermia group and routine treatment group were improved significantly at week after treatment(P<0.05), but the therapeutic effects of mild hypothermia group were better than that of routine treatment group (P<0.05). Conclusions The cervical mild hypothermia auxiliary therapy could significantly inhibit the secretion of stress hormones, make the H-P-A axis stable and promote the stress disease recovery.

The rapid development of stomatology is improving the standard of talent quality and skills gradually,so the innovation of cultivation patterns of the stomatology students is imperative.West China College of Stomatology in Sichuan University is practicing the innovation of cultivation system of stomatological talents by establishing the new teaching and learning plan,adjusting the course system,strengthening the teaching materials construction,and adjusting the evaluation index and so on.The goal of the innovation of cultivation patterns is to foster the stomatological talents which have profound cultural atmosphere,the solid professional knowledge,strong innovative consciousness,and broad international vision.

A new teaching method was developed in the curriculum of Harmful Microorganisms Control Technology.It is characterized by students’ self-learning followed by student’s instruction.Both students and teacher have succeeded in this model after four stages of practice,in which a pleasant learning atmosphere was created in the classroom.An effective interaction between teacher and students was achieved.Students are viewed as main objects in the classroom and they are encouraged to ask questions,to formulate their own ideas,or to find things out for themselves.Thus,students’ abilities including presentation,communication,competition,and cooperation were enhanced.By adapting their role to the new teaching method,teachers have also improved their teaching skill and strategies.

Objectives To study the level and development of serum specific antibody against severe acute respiratory syndrome coronavirus(SARS-CoV)of different populations in SARS pestilence district after SARS outbreak in a general hospital.Discuss SARS sub-clinical infection and protective action of the IgG antibody.Methods Seroepidemiology method,enzyme-linked immunosorbent assay (ELISA)and indirect immunfluorescence assay(IFA)were employed to investigate the changing level of serum antibody to SARS-associated coronavirus in non-SARS population in SARS pestilence district during and after SARS outbreak.The development of IgM and IgG antibody in patients with SARS in 6 weeks after the onset of SARS was studied qualitatively.The level changing of IgG antibody in con- valescent patients with SARS in 82 weeks after the onset was observed dynamically.Results The ELISA test outcome of IgG antibody was negative in 200 non-SARS people who were random samples of normal mass in SARS pestilence district and common community.The positive rate was 0.41% in 487 SARS high risk population tested by ELISA,but showed negative when retested by IFA.The A value level of IgG antibody existed significant difference in non SARS mass during and after SARS outbreak and the later's was higher them the former's(P
