Results The linear ranges of HPLC and TLC were 1 2 - 7 2 ?g (r=0 999 8), 0 2 - 1 0 ?g (r=0 995 7). The average recovery and RSD were 102 2%, 3 39% (n=6) and 100 9%, 2 68% (n=6) respectively. Conclusion Both of two methods can be used for the quality control of diosgenin in Rhizoma Paridis.

Objective To evaluate the value of ATP content of CD4+ T lymphocytes in the diagnosis of infection and its correlation with drug concentrations in renal transplant recipients.Methods 45 renal transplant recipients were reviewed from May 2010 to October 2011.There were 33males and 12 females,aged from 21 to 58 years old.The recipients were divided into non-infection group (n =34) and infection group (n =11) according to their clinical manifestation.11 cases of infection were diagnosed by the chest X-ray,CT imaging manifestations and etiological examination,among them 5 cases were pulmonary infection,4 cases were upper respiratory infection,1 case was urinary tract infection and 1 case was perineal abscess.23 healthy volunteers were enrolled as the control group.They were detected ATP content of CD4+T lymphocytes by Immuknow method.Thetrough concentrations of the FK506 and CsA were detected by microparticle enzyme immunoassay and fluorescence polarization immunoassay,respectively.The hs-CRP concentration was detected by immunoturbidimetry.Results The ATP content of CD4+ T lymphocytes of the control group,non infection group and the infection group were (295±74) μg/L,(35± 189) μg/L and (212± 155) μg/L respectively.The levels of ATP of infection group were obviously lower than the control group and non-infection group.There were statistically differences (P ＜0.05).24 recipients were followed up dynamicly.There were 4 cases whose ATP value was lower than the postoperative average levels in 5 infection recipients.The hs-CRP concentration of infection group were (12.4±4.8) mg/L,obviously higher than the non infection group's (3.3 ± 4.7) mg/L and the control group' s (0.5 ± 0.5) mg/L.There were statistically differences (P＜0.05).The ATP content of CD4+ T lymphocytes were no significant associated with drug trough concentrations (P＞0.05).Conclusions Low ATP level after renal transplantation is a risk factor for infection recipients.Immuknow cell function assay can make up for the inadequacy of the drug concentration monitoring,reduce the risk of infection,and guide clinical immunosuppressive adjustment.

Objective To evaluate the effect of health education on controlling endemic fluorosis in Shaanxi Province between 2004 and 2006. Methods Hanbin, Pingli, Ziyang and Hanyin were selected for the investigation in 2004;in addition to the four areas, Zhengping, Shiquan and Langao were also for the investigation in 2006. Two schools were selected in each area, and 2 villages as the investigation spots. Fifty pupils in the fifth grade in each school, and 30 housewives between 25 - 50 years old in each village were chosen as the research subjects. Referring to the health education questionnaire in Technique Scheme of Endemic Disease Prevention Granted by Central Government of 2004, the degree of health education of endemic fluorine, arsenic poisoning in pupils and housewives were investigated. Results In 2004 and 2006, the average mark of pupils in school was 54.7 and 83.6, the pass rate was 57.5% (230/400) and 90.2% (629/697), respectively;the average mark of housewives was 59.7 and 83.9, the passing rate was 59.6% (143/240), 87.6%(338/386) respectively, indicating that the outcome was improved obviously in 2006 compared to that in 2004. Conclusions In the past three years, health knowledge of endemic arsenic and fluorosis has been improved among pupils and housewives in these areas.

Hepatotoxicity of cyclosporine A was investigated in 366 patients who received renal allografts, of whom 94 (25.68%) presented hepatotoxicity and 13 (3.55%) died. Hepatotoxicity appeared between 7 and 84 d, and lasted for 5 to 96 d. Our study suggested that cyclosporine A is not suitable for older patients with positive HBsAg and liver disfunction.

[ ABSTRACT] AIM:To evaluate the effect of intravenous injecting plasmid encoding interleukin-19-IgG on exper-imental autoimmune myocarditis ( EAM) in rats.METHODS:Cardiac myosin was emulsified with equal volume of com-plete Freund’ s adjuvant.The animal model of EAM was established by injecting with the preparation in both footpads of the Lewis rats.The rats were intravenously injected with the plasmid encoding IL-19-IgG on day 6.Echocardiography was per-formed before the rats were sacrificed on day 17.The effect of IL-19-IgG plasmid injection was evaluated by measuring the heart weight/body weight, myocarditis area, relative expression levels of atrial natriuretic peptide ( ANP) and brain natri-uretic peptide (BNP) in the hearts.The mRNA expression levels of related cytokines including IL-18, IL-1β, IL-12p35 and IFN-γwere detected.RESULTS:The rats in model group showed significant myocardial damage and a decrease in the left ventricular functions.The rats in the treatment group injected with IL-19-IgG plasmid showed an improvement of the cardiac functions.The ratio of heart weight/body weight, the area of myocarditis and the mRNA levels of ANP and BNP were significantly lower in IL-19-IgG treatment group than those in model group.The mRNA levels of IL-18, IL-1β, IL-12p35 and IFN-γwere also significantly decreased in IL-19-IgG treatment group.CONCLUSION:Intravenous injection of plasmid encoding IL-19-IgG effectively prevents the development of the left ventricular remodeling and myocardial damage in EAM rats.

Objective To study osteogenic courses and features of human osteoblasts cultured in vitro and seeded into alloplastic decalcified cancellous bone.Methods Human osteoblasts isolated from normal human perios- teum were cultured and amplified in vitro.Thy configuration and developing manners of osteoblasts were observed. Then osteoblasts were seeded into alloplastic decalcified cancellous bone.Thy composites were implanted and cultured in thy body of athymic mice.The specimens were obtained 8 weeks later.Osteogenic characteristics were observed by scanning electron microscope.Results Osteoblasts isolated from human periosteum developed well and proliferated rapidly in vitro.Island new bone formation could be observed histologically 8 weeks after the composites of os- teoblasts and alloplasric decalcified cancellous bone were implanted and cultured in the body of athymic mice.Conclu- sion Calcified bone can be formed by seeding osteoblasts into alloplastic decalcified cancellous bone,which may be a new kind of bone graft source to construct bone defects.

Objective:To understand the reliability and validity of quality of life instruments for cancer patients-brain neoplasm [QLICP-BN (V1.0)], a self-developed quality of life scale for cancer patients.Methods:The quality of life of 112 patients with brain neoplasms in Yunnan Cancer Hospital from March 2012 to November 2013 was measured. The general data questionnaire and QLICP-BN (V1.0) were used for data collection. The reliability, validity and responsiveness of the scale were tested, and then the metric characteristics of the scale were evaluated.Results:The split-half reliability of the total score of the scale was 0.95, the Cronbach αcoefficient was 0.92, and the test-retest correlation coefficient rwas 0.78. After extracting common factors by the principal component method and rotating with the maximum variance, the specific module obtained three principal components, and the cumulative variance contribution rate was 64.18%. The score of specific module was 75.30±17.44 before treatment and 78.91±12.20 after treatment ( t=-2.481, P=0.015). The total score of scale before treatment was 65.26±12.29, and that after treatment was 69.62±10.41, with a statistically significant difference ( t=-4.492, P<0.001). The total responsiveness of the scale was 0.456, showing moderate responsiveness. Conclusion:QLICP-BN (V1.0) has good reliability, validity and a certain degree of responsiveness. It can be used as a measurement tool for the quality of life of patients with brain neoplasms in China.

Objective To develop an interlocking-style vascular shunt device for the treatment of distal limb ischemia resulting from vascular disconnection and defect.Methods A one-way interlocking buckle was designed with the space between the clamping teeth being 0.5 mm,which prevented the device from moving backwards and fixed the vessel and shunt tube conveniently.The interlocking buckle combined with silicone tube was used to connect the two ends of the defected vessel,which was compared with conventional method by suture ligation and silicone tube by the tests on vessel bursting pressure and tensile biomechanics.Results The vessel repaired with the developed device behaved better than that by the conventional method in the tests on vessel bursting pressure and tensile biomechanics (P＜0.05).Conclusion The vascular shunt device can be used for the treatment of distal limb ischemia resulting from vascular disconnection and defect,and thus facilitates the vascular graft in rear hospital after evacuation.
