Chinese Journal of Primary Medicine and Pharmacy 2010;17(18):2449-2451
Objective To evaluate the clinical value of the quantitative detection of plasma 1,3-β-D-glucan in penicilliposis marneffei. Methods The 1,3-β-D-glucan concentrations were detected by using a G test. Results In 60 New Zealand rabbits infected by Penicillium marneffei,the levels of 1,3-β-D-glucan were positively correlated with infectious severity. The sensitivity, specificity, positive predictive rate and negative predictive rate were 88.3%、100%、 100% and 58.8% respectively,which were significantly higher than those of the control group(P <0.01 ).Conclusion The quantitative method for the detection of 1,3-β-D-glucan in plasma was simple,sensitive and reliable, and could be used as the assisting diagnosis of penicilliposis marneffei at early stage.

Objective To study the non-covalent binding between the tectoridin(TE) and plasma proteins.Methods The molecular weights of TE,human serum albumin(HSA),?1-acid glycoprotein(AAG) and the protein-drug complexes were measured by the electrospray ion trap mass spectrometry(ESI-MS).The maximum stoichiometric ratios were obtained according to the molecular weight change of the complexes before and after binding reaction.The binding constants(K) of the complexes were calculated by the Scatchard equation.The main sorts of binding force of the complexes were deduced according to the relationship between the reaction temperature and the thermodynamic parameters(?H and ?S).Results The K of the complexes were 1.914?104 mol/L for TE-HSA and 5.893?104 mol/L for TE-AAG,and the number of binding sites were 7.8 and 3.3,respectively.The main sorts of binding force between TE-HSA or TE-AAG were static-electricity gravitation.Conclusion ESI-MS is a good method for studying of the TE-protein non-covalent binding with some advantages in sensitivity,high-speed,and accuracy.

BACKGROUND:After knee joint replacement, patients are often treated with Rivaroxaban and Enoxaparin Sodium for postoperative anticoagulation, avoiding the formation of deep vein thrombosis in lower limbs. OBJECTIVE:To explore the application effects of different anticoagulant drugs in patients with knee joint replacement. METHODS:Ninety patients underwent knee joint replacement in Xiangya Second Hospital of Central South University from July 2011 to July 2014, were randomly divided into two groups, with 45 patients in each group. The experimental group was treated with Rivaroxaban, while the control group was treated with Enoxaparin. RESULTS AND CONCLUSION:Postoperative drainage volume, total blood transfusion, bleeding index, quantity of blood platelet, activated partial thromboplastin time, thrombin reduction time, whole blood viscosity, plasma viscosity, D-dimer coagulation index, HSS score at postoperative 2 weeks, average ecchymosis area, average thigh circumference, and average leg circumference were significantly better in the experimental group, than in the control group (P<0.05). The incidence of deep vein thrombosis of lower limbs in the experimental group was lower than that in the control group (P<0.05). Experimental findings indicate that, both Rivaroxaban and Enoxaparin can exert anticoagulation effect during the knee joint replacement, and Rivaroxaban is better.

Objective To assess the clinical significance of three-dimensional speckle tracking imaging (3D-STI) in the evaluation of left ventricular myocardial function in breast cancer survivors with postoperative anthracycline-based chemotherapy.Methods A total of 51 breast cancer survivors with postoperative anthracycline-based chemotherapy were recruited and 31 female healthy volunteers as the controls.Conventional echocardiography and 3D-STI derived parameters [including global longitudinal strain (GLS) and global area strain (GAS)] were measured before and at 3 and 6 anthracycline-based chemotherapeutic cycles.The receiver operating characteristics (ROC) curve was constructed to determine optimal sensitivity and specificity of 3ID-STI derived parameters for the prediction of future cardiotoxicity.Results In comparison with the controls and baseline cases,GLS and GAS deteriorated significantly (P < 0.05 for both).No statistical difference in GCS and conventional parameters showed before and after the initiation of chemotherapy (P <0.05,respectively).The ROC curves showed that GAS as the best 3D-STI predictor of patients who develop cardiotoxicity during the follow-up.The area under ROC(AUC) of GAS was 0.894,and its optimal cut-off value was-28.4%,with a specificity of 88.0% and a sensitivity of 82.9%.AUC of GLS was 0.802,and its optimal cut-off value was-14.3%,with a specificity of 62.0% and a sensitivity of 85.4%.Conclusions Early decreases in GAS and GLS based on 3D-STI may allow the prediction of subsequent cardiotoxic development accurately in breast cancer survivors with postoperative anthracycline-based chemotherapy.

ObjectiveTo explore the resilience and mental health of recruits during training,and to investigate mutual prediction of resilience between mental health and psychological stress to provide the scientific evidence for the mental health training and psychological selection of recruits.MethodsConnor-Davidson resilience questionnaire ( CD-RISC),symptom checklist ( SCL-90 ),psychological stress self-evaluation test ( PSET),satisfaction with life scale (SWLS),positive and negative affect scale (PANAS) were applied to 650 recruits in 2011 before starting training and after two months of training.Results ① Chinese recruits had good resilience,and the CD scores of pre-and post-test were (61.60 ± 14.36) and (61.41 ± 14.55 ) respectively.②Mental health (SCL-90) of two tests were good in recruits.③ Correlation analysis showed that the same premise of phase correlation,resilience (pre-test) could significantly predict mental health (post-test) ( β =0.070,P < 0.05 ),mental health ( pretest) could not predict resilience (post-test) (β =0.015,P > 0.05 ).Resilience (pre-test) could significantly predict psychological stress (post-test) ( β =0.075,P < 0.05 ),psychological stress (pre-test) could not predict resilience (post-test) (β =0.017,P > 0.05 ).④ Compared with high resilience group,low-resilience group of recruits had higher total score of SCL-90 and psychological stress and less positive emotion,more negative emotion and lower life satisfaction.ConclusionThe recruits training have good resilience.Resilience of recruits have predictive ability to mental health,psychological stress during training.

BACKGROUND: Recently emerged immunosuppressive scheme combined with basiliximab following liver transplantation, such as the early steroid withdrawal or half amount of steroid. Many studies demonstrated that it would not increase the rejection rate in reducing the use of steroid. However, there were rare reports addressing whether it was safe and effective to replace the steroid by basiliximab. OBJECTIVE: Through the application of non-steroid and early steroid withdrawal immunosuppressive scheme in patients of hepatocellular carcinoma following liver transplantation, to evaluate the therapeutic effect and safety of two treatments. METHODS: A total of 80 patients of hepatocellular carcinoma receiving liver transplantation were divided into the experimental and control group. In the experimental group, 33 patients were applied with non-steroid treatment (Tacrolimus+mycophenolate mofetil+basiliximab); additionally 47 patients were applied with early steroid withdrawal treatment (Tacrolimus+mycophenolate mofetil+ steroid). Steroid was reduced gradually from the first day after transplantation to discontinuation after 1 month. The rates of rejection, infection, cancer recurrence and 1 -year survival were measured. RESULTS AND CONCLUSION: Compared to the control group, the rates of infection and cancer recurrence were significantly smaller in the experimental group (P < 0.05). However, there was no significantly difference between 2 groups in the rates of rejection and 1 -year survival (P > 0.05). It revealed that the non-steroid treatment can be safely and effectively applied in the patients with hepatocellular carcinoma following liver transplantation. The non-steroid treatment can significantly cut down the infection rate and cancer recurrence rate, which has no effect on the rejection and 1 -year survival rate.
