0.05).Conclusion The serum cTnT is not useful for diagnosing the severity of anthracycline induced cardiactoxicity.

Objective To explore the relationships of quality of life ( QOL ) and functional status in patients with malignant bone tumors after operation. Methods European organization for research and treatment of cancer quality of life questionnaire C30 (EORTC-QLQ-C30), social support revalued scale (SSRS) and Karnofsky performance scale (KPS) were used to investigate the levels of QOL, social support and functional status. The correlations between them were explored. Results The overall score by QOL was (58.33 ± 18.94). The score by KPS was positively related to somatic function, role function, social function, and general health status (P<0.01), but negatively related to tiredness, pains, insomnia and financial burden (P<0.01). Conclusions The QOL in patients with malignant bone tumors after operation is at a lower level and the function is at a medium level. Nurses should assess the function and make out interventional measures for them so as to improve their QOL.

Objective To study the correlation between the main parameters and the effect of repression in MR fluid attenuated inversion recovery(FLAIR).Methods 0.5 unit was used in this experiment.The protein aqua of different material appearance and concentration was prepared.FLAIR was performed using the tube imitative experimented method and with different paramters.The best scan parameters were selected by comparison each other and their relativity was analysed.Results The best technical parameters:TR=4000~5000 ms,TE=90~100 ms,TI=1800~2000 ms.Conclusion TI is the key parameter in determining the repression effect,TR and TE only determine the scans time and layer number.FLAIR's repress result is stable,and it can estimate the protein content in the protein aqua.

BACKGROUND: Herbal wines are an important part of the traditional Chinese medicine. The traditional medicated wine, lishizhen herbal wine,which can strengthen the immune function, has long been used for some chronic diseases. But,its mechanism remains unclear.OBJECTIVE: To explore the immune pharmacodynamics of lishizhen herbal wine and to observe its effect on the immune organs (spleen,pancreas) and lymphocyte transformation rate in mice.DESIGN: A randomized controlled experiment based on the observation of the experimental animals.SETTING: Department of integrated traditional Chinese and western medicine and the department of pharmacology of a university hospital MATERIALS: The experiment was completed at the Central Laboratory of Zhongnain Hospital of Wuhan University from September 2000 to December 2000. A total of 90 healthy Kuming mice were involved in the study.METHODS: Different doses of the herbal wine,cartinellin and the same volume of distilled water were given to the experimental animals. The drug administration was orally injected directly to the stomach of the animals once a day and 10 days consecutively. One hour after the last administration,the animals were put to death. Then,the thymus gland and the spleen were taken out and weighed to calculate the indexes of the thymus gland and the spleen. In the last three days of the administration phytohemagglutinin(PHA)was injected intramuscularly at a dose of 10 mg/kg once per day. Two hours after the last administration, the tails of the mice were cut out, the blood samples were taken to perform the Wright' s staining,and 100 lymphocytes were counted under immersion and the transformation rate was calculated.MAIN OUTCOME MEASURES: Primary results: ① The effect on the immune organs of normal mice; ② The effect of PHA on stimulating the lymphocyte transformation in mice. Secondary results: ③ The death condition of the experimental animalsRESULTS: Different doses of the herbal wine increased the spleen index in different degrees. The effect of medium dose group was obvious[(3.71± 0.78) g/kg] (P <0.05),and the thymus gland index increased a little (P>0.05). The cartinellin in the positive control group increased the spleen index[(3.79±0.91 ) g/kg] and there was no impact on thymus gland index. The transformation rates of the lymphocytes of different groups were increased to a different degree and presented a good quantity-effect relationship,especially the group administered a large dose[(45±14)%] (P<0. 01).CONCLUSION: Lishizhen herbal wine has an effect of increasing cellular immune function.

Objective To investigate the effects of p-cresol on human umbilical vein endothelial cells.Methods The effects of p-cresol on endothelial cell growth,cell cycle,cell morphological change and p21 protein were detected by the CCK-8 assay,flow cytometry assay,inverted microscope and Western blotting.Results P-cresol could inhibit the growth of human umbilical vein endothelial cells in dose-and time-dependent manners (all P ＜ 0.05).The human umbilical vein endothelial cells treated with p-cresol became elongated processes,cloudy cytoplasm,and irregular shapes.The p-cresol stopped human umbilical vein endothelial cells at cell cycle G1 and had no effect on cell apoptosis.The p-cresol could increase protein expression of p21 in a dose dependent manner (P ＜ 0.05).Conclusion P-cresol can increase protein expression of p21,induce cell cycle arrest at G1 stage and inhibit the proliferation of human umbilical vein endothelial cells.

Objective To investigate the curative effect of Quadrant channel transforaminal lumbar interbody fusion(TLIF) in the treatment of recurrent lumbar disc herniation(RLDH).Methods Seventy-six cases patients with RLDH were divided into traditional TLIF group(36 cases) and Quadrant group(40 cases) by the different operation modes.The operation,VAS scores and ODI scores were compared between the two groups.Results Operation time((98.2±18.1) min vs.(118.5±27.2) min,t=3.79,P<0.05),incision length((2.7±0.6) cm vs.(5.5±1.0) cm,t=14.97,P<0.05),intraoperative blood loss((90.7±20.1) ml vs.(170.3±33.5) ml,t=12.71,P<0.05) and intraoperative drainage((43.8±12.4) ml vs.(117.1±28.9) ml,t=14.62,P<0.05) in Quadrant group were less than that in traditional TLIF group.The ambulation time((2.8±0.6) d vs.(6.8±1.1) d,t=19.95.P<0.05) and hospitalization time((7.1±2.0) d vs.(14.2±2.7) d,t=13.11,P<0.05) of Quadrant group were shorter than those of TLIF group.VAS scores in both groups were significantly decreased.VAS in Quadrant group was significantly lower than that in traditional TLIF group from 3 d to 6 months after operation((4.4±1.0,3.9±1.2,3.4±0.8,1.9±0.6,1.3±0.4) points vs.(5.0±1.4,4.5±1.1,4.1±0.9,3.6±0.7,2.5±0.6) points,P<0.05).ODI scores in both groups were significantly decreased.ODI in Quadrant group was significantly lower than that in traditional TLIF group from 1 d to 6 months after operation((36.7±7.1,33.4±6.2,30.7±4.1,27.8±5.3,24.5±5.4,18.4±4.7) points vs.(39.8±6.0,36.8±5.8,33.5±6.6,31.3±5.1,28.9±6.6,22.3±5.2) points,P<0.05).Conclusion The treatment of RLDH by Quadrant channel TLIF has obvious curative effect,short operation time,less trauma,faster recovery and shorter hospital stay.

OBJECTIVE:To determine 5-Fu concentration in serum,peritoneal fluid and tissue by HPLC in patients undergoing rectal cancer operation and receiving regional chemotherapy.METHODS:20 patients who undergoing rectal cancer operation and receiving regional chemotherapy were administered with drugs,whose blood samples were taken from portal veins,peripheral veins,peritoneal fluid and tissues around tumor at 2,5,10,20,30 and 60min,respectively after administration for the determination of 5-FU by HPLC.RESULTS:Peak concentrations in all samples appeared 2 minutes after administration,but lowered gradually thereafter.The drug level in peritoneal fluid was the highest,but was the lowest in the tissue,and that in the portal vein was higher than in peripheral veins.CONCLUSION:For patients who undergoing rectal cancer operation,regional chemotherapy could maintain 5-FU concentration at a higher level in portal vein,peritoneal fluid and tissue around cancer,which has significance in the prevention of metastasis to the local sites and liver after rectal cancer operation.
