Chinese Journal of Primary Medicine and Pharmacy 2006;0(07):-
Objective To observe the clinical therapeutic effect of danshenfenzhen and nutritional support in treating congestive heart failure accompanied with malnutrition on the basis of common treatment.Methods 42 cas- es of congestive heart failure accompanied with malnutrition were randomly divided into 2 groups:test group 21 cases (danshenfenzhen and nutritional support) and control group 21 cases(free diet),in the test group intravenous drip danshenfenzhen and vein nutrition were given if the internal nutrition can not provide enough energy on the basis of count of energy consumption,the serum albumin,total blood lymph cells and body weight were measured.Results After 14 days' treatment in the test group,the serum albumin,body weight and the total lymph cell increased signifi- cantly while in the control group,the serum albumin,body weight and the total lymph cells decreased significantly. Conclusion Intravenous drip danshenfenzhen and nutritional support can improve nutritional status and cardiac function of patients with congestive heart failure accompanied with malnutrition.

BACKGROUND:Abnormal stress is an important factor causing intervertebral disc degeneration. To establish an ideal in vivoanimal model of intervertebral disc degeneration is of great significance for in-depth study on the related pathogenesis. OBJECTIVE:To develop anin vivo rabbit intervertebral disc model and to investigate the relationship between continuous tensile load and intervertebral disc degeneration. METHODS:Twenty-five New Zealand white rabbits aged 6 months old were randomly divided into three groups: blank control (n=5), sham (n=10) and experimental (n=10) groups. The blank control group received no intervention, and the L4/5 segments were removed at the 1st day. The intervertebral disc assistor was used to fix the L4 and L5 vertebral bodies in the experimental and sham groups, the L4/5 segments in the experimental group were loaded 1 MPa axial tensile force, and the L4/5 segments in both two groups were then removed at 14 and 28 days. The changes of L4/5 intervetebral space height and surrounding bone substance were observed by X-ray examination, the morphological changes of the intervertebral disc were observed by hematoxylin-eosin staining, the cell survival was detected by nitro blue tetrazolium staining and mRNA expression levels of aggrecan, collagen type Ⅱ and SOX9 in the intervertebral disc tissues were assessed by RT-PCR at each time point. RESULTS AND CONCLUSION:The radiological manifestations, histological changes, cell survival and mRNA expression levels of aggrecan, collagen type Ⅱ and Sox9 showed no significant difference between the blank control and sham groups. Comparied with the blank control group, in the experimental group, the L4/5 intervertebral space was narrowed with time, the articular surface was coarse, and the upper and lower corpus vertebrae edge appeared to have lip-shaped hyperplasia; the intervertebral disc cells distributed irregularly; the nucleus pulposus was in dehydration and deflation, annulus fibrosus arranged irregularly, and the vacuoles in notochord cells tended to disappear; the expression levels of aggrecan, collagen type Ⅱ and SOX9 were markedly downregulated. These findings suggest that the in vivo rabbit model of intervertebral disc is successfully established, in which continuous mechanical tensile load is further proved to directly cause intervertebral disc degeneration.

Based on the software of traditional Chinese medicine inheritance support system (TCMISS), this article aims to analyze the experience and composition rules for cough from the descendant of Meng He Medical School, Xu Di-hua. The cough cases treated by Xu Di-hua were collected, and recorded into TCMISS (V2.0). Data mining methods such as Apriori algorithm and complex system entropy cluster were used to analyze the medication principles of Xu Di-hua for cough from pathogenesis and therapeutie aspects, and dig out the frequency of the herbs in prescription, core medicine and new combinations. The experience of curing cough from Professor Xu Di-hua were well found in the research. He is good at choosing prescriptions accurately, and pays attention to simultaneous use of cold and moisture drugs with combination of tonification and purgation. He is skilled in adding or reducing materia medica flexibly, as well as regulating lung to relieve cough and eliminating phlegm by clearing heat.

Objective To determine whether the adjustment of the pusher of GTF was useful to decrease the degree of tilting of the femoral Ginther Tulip filter (GTF) in an in vitro caval model. Methods The caval model was constructed by placement of a 25 mm × 100 mm and two 10 mm ×200 mm Dacron graft inside a transparent bifurcate glass tube. The study consisted of two groups: left straight group (GLS) (n =100) and left curved group (GLC) (n = 100). In the GLC, a 10° to 20° angle was curved on the introducer.The distance (DCH) between the caval right wall and the hook was measured. The degree of tilting (DT) was classified into 5 grades and recorded. Before and after the GTF being released, the angle (ACM1, 2)between the axis of IVC and the metal mount, the distance (DCM1) between the caval right wall and the metal mount, the angle (ACF) between the axis of IVC and the axis of the filter and the diameter of IVC (DIVC) were measured. The data were analyzed with Chi-Square test, t test, rank sum test and Pearson correlation test. Results The degree of GTF tilting in each group revealed a divergent tendency. In group LC, the apex of the filter tended to be grade Ⅲ compared in group LS (x2 value 37. 491 ,P <0.01).The differences of most variables between GLS and GLC were considered as statistical significance(16. 60° vs.3.05°, 20.60° vs. 3.50°, -3.90°vs. -0.40°, 2.98 mm vs. 10.40 mm, - 10.95° vs. -0.485°,13. 17 mm vs. 10.06 mm, - 1.70° vs. 0.70°, t or Z values - 12. 187, - 12. 188, -8.545, -51.834,-11. 395,9. 562, -3. 596, P < 0. 01). There exist significant positive correlation between ACM1 and ACF,ACM1 - ACM2 and DCH1 - DCH2 in each group, respectively(r values 0. 978,0. 344,0. 879,0. 627 ,P <0. 01),while significant negative associations are detected between DCH1 and ACF in each group , ACP and ACF in group LC(r values -0.974, -0.322, -0.702,P<0.01). Conclusion The technique of adjusting the orientation of filter pusher had minimized the incidence and extent of GTF filter tilting in vitro.

Objective To study the influence of crosstalk phenomenon on the measurement of gross radioactivity in drinking water.Methods The gross activity in different standard materials with different thickness and area was measured using national standard method.Results There was no obvious change in crosstalk factor with the increase of 241Am powder amount in the measurement,whereas the larger amount of uranium used might lead to larger crosstalk factor.The different measurement channels resulted in different crosstalk factors.The influence of beta radioactivity on alpha radioactivity measurement was significant.On the contrary,the alpha-to-beta crosstalk factor was negligible.The area of sample plate imposed no significant influence on crosstalk factor.Conclusions The gross beta activity can be corrected to decrease the influence of alpha radioactivity using powder standard samples,when simultaneous alpha and beta counting mode is applied in measurement grass radioactivity in drinking water.
