Body fat of 12 male adults were measured by water displacement me-thod(density method) at every morning for 5 successive days. The standard deviation of single observation was 0.29kg calculated by mean residual lung volume method. It was significantly lower than the value (0.5kg) calculated by the ordinary method (p

The optimal plane for measurement of the right ventricular (RV) volumes by real-time three-dimensional echocardiography (RT3DE) was determined and the feasibility and accuracy of RT3DE in studying RV systolic function was assessed. RV "Full volume" images were acquired by RT3DE in 22 healthy subjects. RV end-diastolic volumes (RVEDV) and end-systolic volumes (RVESV) were outlined using apical biplane, 4-plane, 8-plane, 16-plane offline separately. RVSV and RVEF were calculated. Meanwhile tricuspid annual systolic excursion (TASE) was measured by M-mode echo. LVSV was outlined by 2-D echo according to the biplane Simpson's rule. The results showed: (1) There was a good correlation between RVSV measured from series planes and LVSV from 2-D echo (r = 0.73; r = 0.69; r = 0.63; r = 0.66, P < O. 25-0. 0025); (2) There were significant differences between RVEDV in biplane and those in 4-, 8-, 16-plane (P < 0.001). There was also difference between RV volume in 4-plane and that in 8-plane (P < 0.05), but there was no significant difference between RV volume in 8-plane and that in 16-plane (P > 0.05); (3) Inter-observers and intro-observers variability analysis showed that there were close agreements and relations for RV volumes (r = 0.986, P < 0.001; r = 0.93, P < 0.001); (4) There was a significantly positive correlation of TASE to RVSV and RVEF from RT3DE (r = 0.83; r = 0.90). So RV volume measures with RT3DE are rapid, accurate and reproducible. In view of RV's complex shape, apical 8-plane method is better in clinical use. It may allow early detection of RV systolic function.

Thirty SHRs were obtained randomly to hypertension, model group, captopril group and Qingre jiangya capsule group. Ten Wistar rats were used as control group. The hippocampus tissue was removed to explore the damage of spontaneously hypertensive rats (SHR) and the protective effect of Qingre jiangya capsule after continuously administered for 14 days. And then the data were processed by principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The research results revealed captopril group was significantly different from the other three groups. The classification of other three groups is also very clear after captopril group removed. This suggested that Qingre jiangya capsule could improve the overall metabolism compared with captopril. Four metabolites were identified: dimethylglycine, glycerophosphocholine, aldosterone and noradrenaline. Hypertension hippocampus damage may mainly be expressed in tyrosine metabolism, aldosterone-regulated sodium, vascular smooth muscle contraction reabsorption, and Qingre jiangya capsule could reverse the hippocampus tissue damage of SHR.

Enhancing medical students' humane quality education is an urgent requirement for modem medical mode transformation for medical education.The pharmacology teachers of Chongqing Medical University follow the modem education concepts and fully search the human spirit materials hidden in pharmacology,then actively explore how to integrate the humanity spirit education into the pharmacology teaching to achieve the changes of from exam-oriented education to quality education.

OBJECTIVETo study the effect of sophoridine against bone cancer pain in bone cancer pain model rats induced by W256 tumor cells and its mechanism.

METHODThe rat model of bone cancer pain was reproduced by injecting W256 tumor cells into the rat marrow cavity. Ten days after the model establishment, 36 rats were selected and randomly divided into the model control group and the sophoridine treated group. At the same time, other 10 rats with sham-operation were selected to be the normal control group. Since the 15th day after the operation, rats in the treated group had been given sophoridine (25 mg x kg(-1)) for 10 days. The mechanical withdrawal threshold and the thermal withdrawal latency of each group were measured before and after the treatment. After the last treatment, the radiological and histopathological observation shall be conducted for sick legs of all rats. The expressions of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in tumor tissues were detected by mmunohistochemistry.

RESULTSophoridine could significantly increase the mechanical withdrawal threshold and the thermal withdrawal latency (P < 0.05, P < 0.01), significantly relief the bone injury caused by W256 tumor cells (P < 0.05), and notably down-regulate the COX-2 and VEGF expressions in tumor tissues (P < 0.05).

CONCLUSIONSSophoridine has the effect in relieving pain and inhibiting tumor progression in bone cancer pain rats induced by W256 tumor cells. Its mechanism may be related to the down-regulated expressions of COX-2 and VEGF.

In this paper, application of biotechnics in the identification of traditional Chinese medicinal herbs, and the production and cultivation of their excellent species was discussed, and the relevant references about usage of biotechnics in TCM researches published in recent decade were summarized and analysed. Lots of literature showed that biotechnics played important roles in the quality identification of Chinese medicinal herbs and the researches on new drugs of TCM.

· AIM: To explore the effects of C3F8 tamponade on hypotony on or after primary operation and the prognosis of severe ocular trauma.· METHODS: Twenty-six cases (26 eyes) of severe ocular trauma were treated with pure C3F8 tamponade on or after primary operation. IOP was observed, and the curative effect of C3F8 tamponade was observed on secondary operation with prognosis evaluated.· RESULTS: Hypotony improved in 23 eyes postoperatively,in which 18 eyes with edematous and cloudy cornea, 15 eyes had clear cornea after gas tamponade. Retina was reattached under the gas action in 21 eyes during the secondary operation. Visual acuity improved in 22 eyes, remained unchanged in 3 eyes and decreased in 1 eye during the follow-up of 3-12months.· CONCLUSION: Application of pure C3F8 tamponade on or after primary operation can effectively improve hypotony after severe ocular trauma and benefit a better prognosis.
