Objective To evaluate the effects of the chronic Keshan disease's self-management in Liangshan Prefecture of Sichuan Province. Methods According to "The Serf Management Program of Chronic Keshan Disease in Liangshen Prefecture of Sichuan Province", 56 chronic Keshan disease patients were selected in the personalized self-manngemant evaluation under the instructions by endemic disease specialists and the rural doctors. Evaluation was based on changes of indexes such as the clinical symptoms, general health conditions, the electrocardiogram, X-ray, the heart function, etc, before treatment and 3 and 6 months following the treatment. Results Clinical signs and symptoms of the patients were significantly improved 3 and 6 months after the treatment, and the improvement was more obvious 6 months than 3 months following the treatment(P<0.05 or< 0.01). After treatment for 3 months, the patients'electrocardingram and heart function did not show obvious change (X2=0.05,039, P0.05); hut obvious improvements Eexcept X ray results(X2=0.61 ,P0.05)] were seen 6 months after treatment (X2=4.36,16.84, P<0.05 or<0.01). Altogether, among the 56 patients evaluated after treatment for 6 months, none achieved the clinical cure standard, 26 cases(46.3%) showed significant improvement, 17 cases (30.4%) were stable, 5 cases (8.9%) were aggravated,one case (1.8%) lost contact, and 6 cases (10.6%) died. Conclusion The project of the chronic Keshan disease's self-management is suitable for the present situati,on of the endemic regions and can he introduced to many places in our country.

Objective:To observe the clinical effect of acupoint sticking of Chinese medicine at Shenque (CV 8) for preventing spleenstomach disharmony caused by venous analgesia pump.Methods:A total of 120 post-surgery patients using venous analgesia pump and also conforming to the inclusion criteria were randomized into 2 groups by the random number table.There were 58 patients in the control group who received conventional post-surgery nursing care,and there were 62 patients in the treatment group who received acupoint sticking at Shenque (CV 8) on the basis of conventional nursing care.After treatment,the incidences of postoperative nausea and vomiting,and abdominal bloating were measured.Results:The total incidence of nausea,vomiting and abdominal bloating in the treatment group was 11.3％,versus 39.7％ in the control group,and the difference of the incidence between the two groups showed a statistical significance (P＜0.05).In comparison of the severity of spleen-stomach dishormony which happened during 72 h after surgery,cases in the treatment group showed lower severity than those in the control group (P＜0.05).Conclusion:Acupoint sticking at Shenque (CV 8) can effectively prevent spleen-stomach disharmony caused by venous analgesia pump,which will alleviate sufferings of the patients.

This study is to establish a method for simultaneously determination of five nucleosides and nucleobases, including hypoxanthine, uridine, adenine, guanosine and adenosine in Rehmannia glutinosa Libosch. which was collected from different regions in China. A Diamonsil C18 column (250 mm x 4.6 mm, 5 microm) was used. Acetonitrile and 0.04 mol L(-1) potassium dihydrogen phosphate solution were adopted as mobile phase with gradient elution. The flow rate was 1 mL min(-1) and column temperature was 30 degrees C. The detection wavelength was at 254 nm. The method had good linearity over the range of 1.0 - 16.0 microg mL(-1) (r2 = 0.999 8), 5.0 - 80.0 microg mL(-1) (r2 = 0.999 8), 1.0 - 16.0 microg mL(-1) (r2 = 0.999 5), 1.25 - 20.0 microg mL(-1) (r2 = 0.999 8) and 1.0 - 16.0 microg mL(-1) (r2 = 0.999 8) for hypoxanthine, uridine, adenine, guanosine and adenosine, respectively. The average recoveries were between 98.8% and 100.7%. The content of hypoxanthine, uridine, adenine, guanosine and adenosine in Rehmannia glutinosa Libosch. from different regions was significantly different. This established method was sensitive and reliable for the quantification of five chemical constituents in Rehmannia glutinosa Libosch.

Image-guided neurosurgery is playing a more and more important role in modern neurosurgical therapy. The current trend is to construct an open platform for image-guided neurosurgery, to make applied researches of various new therapeutic techniques, and finally to integrate them into the clinical image-guided neurosurgery system.

Noise of ECP (external counterpulsation) comes from the frequent movement of the electromagnetic valve iron core hitting the top of the valve body and the orifice of the bottom, and the high pressure and large air stream rubbing the orifice. This article studies the method to reduce mechanical noise of the electromagnetic valve core, that is to reduce the above movement energy and the hitting force. The method is used in ECP devices with grafying results. This noise controlling technology may reduce the noise of the electromagnetic valve from higher than 50dB to less than 25dB.

At the present time, training student to have innovative and applied ability has become the object of higher education in China. In this paper, it was proposed that teacher was obligated to create certain atmospheres in classroom to achieve this goal, including friendliness, harmoniousness, encouragement, happiness, discussion, exploration, etc. At the same time, student-centered study should be encouraged. Through these measures, the spirit of innovation will be inspired, the applied ability will be trained, the capability of self-study will be enhanced.

OBJECTIVETo study on effects of acupuncture at a same point at physiological or pathological state on brain functional imaging.

METHODSElectroacupuncture was given at Neiguan (PC 6) of the healthy senile persons (normal group) and the patients of Alzheimer's disease (AD group), and they were scanned on a 1.5 T MRI scanner and the data of functional magnetic resonance imaging (fMRI) were analyzed by Statistical Parametric Mapping (SPM99). The functional imaging of different brain regions were obtained from both the healthy group and the AD group.

RESULTSBoth the frontal lobe and the temporal lobe were activated in varying degrees by electroacupuncture at Neiguan (PC 6) in the healthy group. However, the frontal lobe, the temporal lobe and the cingulate gyrus as well as the cerebellum were activated in varying degrees and other brain regions were not activated by electroacupuncture at Neiguan (PC 6) in the AD group.

CONCLUSIONAcupuncture at Neiguan (PC 6) can activate functions of different brain regions in the healthy group and the AD group, indicating that acupuncture at Neiguan (PC 6) has different effects on functional magnetic resonance imaging in different functional states.

OBJECTIVETo investigate the induction and culture of adventitious root of Panax notoginseng.

METHODThree ways, induction from the explants of three-year-old P. notoginseng. The explants of regenerated shoots and calluses, were used to induce adventitious roots. The effects of 2, 4-dichlorophenoxyacetic acid, indole-3-butyric acid and naphthylacetic acid on adventitious root induction were investigated respectively. The effects of four modes of separating adventitious roots from the parent tissues on culture in vitro were compared.

RESULTAdventitious roots were successfully induced by three methods, of which the young flower bud callus was the best material for the induction of adventitious root. Indole-3-butyric acid possessed the strongest potency for induction. The liquid culture system was established by continuous culture of adventitious roots together with their parent tissues before separated.

CONCLUSIONThe acquisition and culture in vitro in liquid culture system of adventitious roots of P. notoginseng lay a foundation for the next investigation.
