Objective To explore the application of humanistic nursing model in clinical nursing in psychotic patients. Methods 132 patients from January,2007 to January,2010 were retrospectively analyzed and randomly divided into the research group and the control group with 66 patients in each group.The control group was given routine nursing,the research group was given additional humanistic nursing based upon routine nursing.The nursing effect was compared between the two groups. Results The research group had apparent advantage in hospitalization time,satisfactory degree and treatment compliance comparing with the control group. Conclusions Humanistic nursing can wholly include the physiological,psychological,social,mental and culture factors of patients,so it can satisfy individual nursing care for psychotic patients.

Objective To explore the serum lactic acid,transaminase and their relationship with liver pathological damage in sepsis rats,whether a correlation exists between serum lactate clearance rate and transaminase in sepsis rats,and whether they can be used as indicators for the prediction and evaluation of septic rats liver injury.Methods A total of 150 clean Sprague-Dawley (SD) rats was divided into normal group (n =50),sham operated group (n =50),and the cecal ligation and puncture (CLP) (n =50).Ten rats were killed after successful surgery at the 6th,12th,24th,48th,and 72nd hour in CLP group,respectively.At each time point,10 normal rats and 10 sham-operated rats were taken as a control in the corresponding time point.The liver tissue was obtained for pathological analysis.The levels of lactate and liver transaminase were detected and the lactate clearance rate was calculated.The levels of lactate and transaminase at each time point were statistically compared.The correlation analysis was performed among serum lactate,transaminase,and liver damage pathological changes.Results The rat hepatocytes in CLP group begin to appear at the 6th hour,and the damage was gradually enhanced at the 12th,24th,and 48th,and up to the worst damage at the 48th time point.The levels of lactate and alanine aminotransferase (ALT)in CLP group at the 12th and 24th hour were significantly elevated compared with the normal and sham operation groups (P ＜0.05); The level of aspartate aminotransferase (AST) in CLP group at the 6th,12th,24th,48th,and 72nd hour was significantly elevated compared with the normal and sham operation groups (P ＜ 0.05).A positive correlation was found between the levels of ALT and lactate (r =0.766,P ＜0.05),and a negative correlation was found between lactate clearance rate and ALT (r =-0.712,P ＜0.05).Conclusions In septic rats,both lactate and lactate clearance rate were correlated with ALT,and they were correlated with liver pathological damage.The level of lactate,lactate clearance rate,and ALT could be used as the key indicators to predict liver damage in septic rats.

Objective To set up a method to detect the mutation of CYP2C9 1075A ＞ C and VKORC1-1639 G ＞ A in clinical practice,investigate the distribution of CYP2C9 1075A ＞ C and VKORC1-1639 G ＞ A in Beijing Han native,and evaluate the correlations between CYP2C9 1075A ＞ C,VKORC1-1639 G ＞ A and Warfarin maintenance dose,so that the results will contribute to Warfarin therapy.Methods A total of 145 Han Beijing patients received long-term Warfarin anticoagulant therapy orally in the people's hospital between May to September in 2011 were enrolled in this study.The patients suffer from atrial fibrilation,thromboembolism and heart operation respectively.The ARMS-TaqMan real time PCR technique was used to detect the mutation of CYP2C9 1075A ＞ C and VKORC1-1639 G ＞ A.The data were collected on gender,age and BSA.The correlations between stable warfarin dosage and each factor were analysised.Results The detection limit of ARMS-TaqMan real time PCR technique was 105 copies/ml in this assay.The intra-and inter-coefficients of variations (CV) were less than 5.5％ and less than 9.0％ respectively.The coincidence rate of ARMS-TaqMan real time PCR and direct sequencing was 100％ for testing 50 paralled samples.Among the 145 patients,the frequencies of CYP2C9 1075 AA,AC and CC was 93.8％ (136/145),6.2％ (9/145),0(0/145) respectively.The frequencies of VKORC1-1639 GG,GA and AA was 0.7 ％ (1/145),21.4％ (31/145),77.9％ (113/145) respectively.Allele frequencies of genotypes were in Hardy-Weinberg equilibrium.Every patients' INR was within range 2.0-3.0.Among the 145 patients,dosage requirements were higher in CYP2C9 1075 AA phenotype than that in AC type (F =0.199,P ＜0.05) and were higher in VKORC1-1639 GA phenotype than that in AA type (F=1.745,P ＜0.001).Irrespective of other factors,age,BSA,CYP2C9 1075 and VKORC1-1639 was accounted for 11.9％,12.9％,4.4％ and 16.7％ of interindividual variation of Warfarin dosage respectively.Linear stepwise regression analysis was used to identify factors contributing to Warfarin stable does.The final equation accounted for 40.4％ of interindividual variation of Warfarin dose.Conclusions The ARMS-TaqMan real time PCR technique was established to analyse CYP2C9 1075 and VKORCl-1639 genotype.The technique can achieve the needs of clinical practice.Warfarin dosing by multivariable regression equation in patients could increase efficiency for Warfarin dose adjustment,and could give suggestion for the individualization and rationalization for Warfarin dose.

AIM: To establish a high performance liquid chromatography (HPLC) method to determine the concentration of valsartan in human plasma. METHODS: Using lrbesartan as internal standard, valsartan in plasma samples was determined by HPLC with liquid-liquid extraction, achieved by the column of Agilent ZORBAXSB-C_ 18( 150 mm? 4.6 mm, 5 ?m) at room temperature. The mobile phase consisted of a mixture acetonitrile : water : phosphoric acid : triethylamine was the ratio of 4060 1.0 1.5 (v/v), pumped at a flow rate of 1.0 ml?min~ -1, the wavelengths of fluorimetric excitation and emission were set at 265 and 378 nm respectively. RESULTS: The drug-free plasma did not interfere with the determination of drugs and internal standard. There was good linear relationships (1/C~2 weighted) between peak area ratio of valsartan to internal standard and C (r= 0.9996) within the range of 25-2 500 ng?ml~ -1. The precision of within-day and between-day was good. The lower limit of quantification was 25 ng?ml~ -1. The analytes reconstituted in the mobile phase were also stable at ambient conditions for at least 24 h. Furthermore, valsartan was stable for at least three freeze thaw cycles. CONCLUSION: The HPLC method can be used to determine the concentration of valsartan in human plasma.

BMPs(bone morphogenetic proteins.)were first identified as proteins that were able to induce ectopic osteogenesis and were shown to enhance the osteogenic differentiation of both osteoblast-like and osteoprogenitor cells.Clearly the use of BMPs in orthopaedics is still in its formative stage,but the data suggest an exciting and promising future for the development of new therapeutic applications.Identification of a precise mechanism for the factors in the progression may be helpful for clinical treatments.

Pingyangmycin (bleomycin A5 hydrochloride, PYM) is one of the anti-neoplastic agents which have been commonly used to treat venous malformations. However, the underlying mechanism by which PYM treats venous malformations remains poorly understood. It was reported that venous endothelial cells could recruit neutrophils via adhesion molecules (E-selectin, ICAM-1, ICAM-3, VCAM-1) during the acute/chronic inflammation and subsequent histological fibrosis after sclerotherapy with PYM. This study explored if the expression of E-selectin, ICAM-1, ICAM-3 and VCAM-1 in human venous malformation endothelial cells could be affected by PYM. HVMECs were cultured from human venous malformation tissue. Expressions of E-selectin, ICAM-1, ICAM-3 and VCAM-1 on HVMECs in response to PYM were analyzed by cell ELISA. The relative levels of mRNA expression in the cells were semi-quantified. The results showed that PYM up-regulated the expressions of E-selectin, ICAM-3, VCAM-1 and ICAM-1 in both time- and concentration-dependent manner. Our findings suggested that PYM could induce the expression of adhesion molecules in HVMECs, which might be a possible mechanism by which sclerotherapy by intralesional injection of PYM treats venous malformations.
