[Effects of Rutin on Myocardial Enzyme and Cardiac Morphology in Diabetic Mice].

Objective: To study the effects of rutin on myocardial enzyme in serum and myocardial morphology in diabetic mice induced by streptozotocin (STZ).

Methods: A model of type 1 diabetic mice was established in 48 male kunming mice with daily intraperitoneal injection of streptozotocin (STZ) 62.5 mg/kg for 5 consecutive days.

The Metabonomic Studies of Tongue Coating in H. pylori Positive Chronic Gastritis Patients.

In Traditional Chinese Medicine (TCM), tongue diagnosis (TD) has been an important diagnostic method for the last 3000 years. Tongue coating can be used as a very sensitive marker to determine the progress of chronic gastritis. Therefore, the scientific, qualitative, and quantitative study for the pathophysiologic basis of tongue coating (TC) emerged as a major direction for the objective research of TD.

Pulse signal analysis of patients with coronary heart diseases using Hilbert-Huang transformation and time-domain method.

Objective: To explore characteristic of pulse signal to distinguish patients with coronary heart diseases (CHD) from patients without CHD and healthy adults, and accordingly evaluate the potential role of pulse signal to diagnosis CHD.

Methods: Totally 407 patients enrolled from 4 collaborating medical centers were assigned to a CHD group (205 patients) and a non-CHD group (202 patients). The healthy control group (62 adults) enrolled from Shanghai University of Traditional Chinese Medicine.

Metabolic markers and microecological characteristics of tongue coating in patients with chronic gastritis.

Background: In Traditional Chinese Medicine (TCM), tongue diagnosis has been an important diagnostic method for the last 3000 years. Tongue diagnosis is a non-invasive, simple and valuable diagnostic tool. TCM treats the tongue coating on a very sensitive scale that reflects physiological and pathological changes in the organs, especially the spleen and stomach.

[Metabolite changes in the greasy tongue coating of patients with chronic gastritis].

Objective: To explore the changes in metabolites in the greasy tongue coating in patients with chronic gastritis.

Methods: Forty chronic gastritis patients presenting with greasy tongue coating, 30 chronic gastritis patients presenting with non-greasy tongue coating, and 20 healthy control persons presenting with light red tongues and thin white coating were enrolled, and the tongue coating was detected by combining artificial diagnosis and the Z-BOX Tongue Digital Analyzer's diagnosis. Samples of all the tongue coatings were collected before treatment.

[Determination of reaction products of epoxypropane in the process of deflagration to detonation transition by emission spectroscopy].

After solving problems of the synchronization of the measuring system, the detection of weak light, and the avoidance of false trigger signal, the instantaneous emission spectra of epoxypropane in the process of deflagration to detonation transition (DDT) with the exposure time of 1-16 micros and the resolution of 0.2 nm were measured. The spectra were acquired from side windows of an explosion shock tube 0.

[Instantaneous emission spectra of epoxypropane in the process of deflagration to detonation transition].

Using an intensified CCD spectroscopic detector (Princeton Instruments, ICCD PI-Max 1024 RB) which can be gated in as little as 5 ns, the synchronization of the measuring system was controlled by a digital delay generator (Stanford Research Systems, DG535), the DG535 was triggered externally by a lab-made electrical pulse generator which transformed the optical trigger signal to an electrical signal, and the light signal from the end window of an explosion shock tube was delivered by an 1 mm in diameter plastic optical fiber to the entrance slit of the spectrometer (grating of 150 g x mm(-1) , central wavelength of 550 nm). The spectrum measurement of the epoxypropane in the process of deflagration to detonation transition (DDT) was then made. The instantaneous emission spectra of epoxypropane at different time of the DDT process with an exposure time of several microseconds were acquired.
