Objective To investigate the effect of low molecular weight heparin (LMWH) on the prevention of deep venous thrombosis in patients with lower limb fracture.Methods 213 cases of peripherally inserted central venous catheter after deep venous thrombosis of lower extremity fractures from February 2014 to October 2016 in our hospital orthopedic surgery were retrospectively analyzed,according to whether patients with low molecular weight heparin were divided into two groups,which did not use low molecular weight heparin in patients with 104 cases as control group,using the low molecular weight heparin in 109 patients as study group,with seven days of treatment as the observation period, the blood rheology indexes of the two groups of patients and the incidence of deep vein thrombosis were analyzed.Results After treatment, the blood viscosity, fibrinogen, and plasma D-dimer levels of the whole blood decreased in both groups, and the levels of plasma D-dimer were significantly lower in the study group than in the control group (P<0.05);the plasma viscosity of the study group was significantly lower than that of the control group (P <0.05).After treatment,the recurrence rate of deep venous thrombosis in the study group was significantly lower than that in the control group ( P<0.05 ); The effective rate of treatment group was 96.33%was significantly higher than the control group 76.92%(P<0.05);study group incidence of adverse reactions 1.83%was significantly lower than the control group 7.69%( P <0.05 ) .Conclusion Low molecular weight heparin can effectively improve the indexes of Hemorheology in patients with lower limb fracture after central venous catheter puncture, reduce the risk of deep vein thrombosis, and have a clear preventive effect.

A novel high performance liquid chromatographic method was developed for the determination of 4-O- methylhonokiol in rabbit plasma and was applied to its pharmacokinetic investigation. Plasma samples were treated by one-fold volume of methanol and acetonitrile to remove the interference proteins. A reverse phase column of SHIM- PACK VP-ODS （150 mm ×4.6 mm, 5.0 μm） was used to separate 4-O-methylhonokiol in the plasma samples. The detection limit of 4-O-methylhonokiol was 0.2 μg/L and the linear range was 0. 012 - 1. 536 mg/L. The good extraction recoveries were obtained for the spiked samples （84.7%, 89.3% and 87.7% for low, middle and high concentrations of added standards, respectively）. The relative standard deviation of intra-day and inter-day precisions was in the range from 0.6% to 13.5%. The pharmacokinetic study of 4-O-methylhonokiol was made and the results from the plasmaconcentration curve of 4-0-methylhonokiol showed a two-apartment open model. This work developed a sensitive, stable and rapid HPLC method for the determination of 4-O-methylhonokiol and the developed method has been successfully applied to a pharmacokinetic study of 4-O-methylhonokiol.

A Web-based technology system was put forward aiming at the actual problems of the long maintenance cycle and the difficulties of the maintenance and repairing of medical equipments. Based on analysis of platform system structure and function, using the key technologies such as search engine, BBS, knowledge base and etc, a platform for medical equipment service technician to use by online or offline was designed. The platform provides users with knowledge services and interactive services, enabling users to get a more ideal solution.

Objective To establish a novel method for simultaneous determination of three ingredients (codeine phosphate, brompheniramine maleate and ephedrine hydrochloride) in compound codeine phosphate solution by using capillary electrophoresis (CE) coupled with electrochemiluminescence (ECL). Methods Based on enhanced ECL intensity of tris (2,2′-bypyridine) ruthenium (Ⅱ) with codeine phosphate, brompheniramine maleate and ephedrine hydrochloride, as well as the linear correlation between enhanced sensitivity intensity and drug concentration, Parameters affecting separation and detection were optimized. Results Under the optimized conditions, we determined the linear range, regression equation and detection limit for the three ingredients. The relative standard deviation of ECL intensity for twelve consecutive injections of 1.0×10~(-5)kg/L standard sample of three kinds of drug was 2.89% for codeine phosphate, 3.76% for brompheniramine maleate and 3.32% for ephedrine hydrochloride, respectively. Satisfactory results were obtained without interference from sample matrixes. Conclusion The method was successfully applied to the determination of three ingredients in oral solution of compound codeine phosphate, with the recovery rate of 100.4% for codeine phosphate, 101.9% for brompheniramine maleate and 99.8% for ephedrine hydrochloride.

Objective To explore the psychological stress of young nurses facing patients' death. Methods Young nurses in emergency department, ICU and hospice care ward (96 cases, research group) and young nurses in other departments(94 cases,control group)from 8 general hospitals were investigated by self-rating anxiety scale (SAS)and serf-rating depression scale (SDS).The results underwent comparison and analysis. Results SAS and SDS score,incidence of anxiety and depression in the research group were higher than those of the control group (P ＜ 0.05). Conclusions Young nurses who face patients' death frequently have high incidence rate of psychological stress.They show low psychological health level which deserves the close attention of nursing managers.

Objective To explore the impact of the variable number of tandem repeats of monoamine oxidase A gene (MAOA-uVNTR) on the intensity of brain activation during the recognition of facial expression in patients with depression and healthy controls.Methods 28 cases of depression,as well as 33 healthy controls who were matched in gender, age and years of education were divided into different genotypes with the methods of polymerase chain reaction (PCR) amplification and 1.5% agarose gel electrophoresis separation.61 cases were scanned to compare the intensity of brain activation in the recognition of happy, sad and neutral facial expression.Results In healthy controls,cases with high-activity genotype showed increased activation in left cuneus,left inferior frontal gyrus, right medial frontal gyrus and left inferior parietal lobule in comparision with carriers of low-activity genotype.In the depressed, compared with patients with low-activity genotype, cases with high-activity genotype decreased activation in bilateral putamen, left postcentral gyrus, left fusiform gyrus, right superior temporal gyrus and right thalamus.Conclusion Healthy controls with high-activity genotype shows the trend of priority for the identification of negative emotion,this genotype may be one of the risk factors for normal people suffering from depression.Patients with high-activity genotype is associated with the inhibitory of positive emotional state, this may attribute partly to the emotional symptoms in such kind of patients more serious.

Objective To investigate the influence of intravenous infusion by double-lumen peripherally inserted central catheter (PICC)on continuous dynamic central venous pressure(CVP)monitoring.Methods In the patient undergoing the double-lemon PICC,continuous dynamic CVP monitoring was performed by a lumen and the intravenous infusion was conducted by another lu-men.Whether the simultaneous venous infusion affecting the values of continuous dynamic CVP monitoring was observed.Results Intravenous infusion through double-lumen PICC had no influence on simultaneously continuous dynamic CVP monitoring (P>0.05),which could influence the values of CVP monitoring when simultaneously using the intravenous infusion pump(P<0.05). The speed of pumping fluid had no influence in a shout time(10 min),with significant difference(P>0.05).The CVP values could recovered to the status before infusion when continuously infusing after stopping using the infusion pump.Compared with before in-fusion,the CVP values after stopping intravenous infusion had no obvious change(P>0.05).Conclusion Intravenous infusion by double-lumen PICC has no influence on continuous dynamic CVP monitoring.But simultaneously adding infusion pump has certain influence on the CVP monitoring values.
