Objective To explore the relationship among personality,job burnout and knowledge sharing behavior of the enterprise employees.Methods The 44 items big five inventory(BFI) ,knowledge sharing inventory and job burnout inventory were administrated to 635 employees online.Results ( 1 ) Agreeableness had a significant main effect on knowledge sharing ( β =0.135, P＜0.01); (2)Cynicism( β = -0.140, P＜0.01) and reduced personal accomplishment( β = -0.125, P＜0.01 ) had a significant effect on knowledge sharing behavior and its two dimensions; (3) Job burnout partially mediated the relationship between agreeableness and knowledge sharing behavior(P＜0.01).Conclusion Enterprise employees' personality had different effects on knowledge sharing behavior,and job burnout was an important mediating role in the relationship above.

Object To probe tentatively into the relations of Terminalia chebula Retz., Terminalia billerica (Gaertn.) Roxb, and Phyllanthus emblica L. between TCM and Tibetan medicine. Methods Textual researches of materia medica were carried out and their history in clinical application were traced. Results T. chebula, T. billerica, P. emblica were all of foreign origin and were introduced into China with Buddhism. As compared in medical practice, the Tibetan autonomony region has their particular choice and preference. Conclusion We should apply modern scientific research achievements to carry out deep mutual exchanges to enrich TCM.

Objective To assess whether the delivery of 100% of the nutritional target from days 4 to 8 in the ICU with enteral nutrition plus supplemental parenteral nutrition(SPN) could optimize clinical outcome .Methods A total of 300 critically ill patients who had received less than 60% of their energy target from enteral nutrition(EN) were randomized to treatment group(n=150) and control group (n=150) .After using the stochastic indicator method after day 3 of admission to the ICU ,one received EN and the other received EN plus SPN during days 4 to 8 ,then we calculated energy targets with indirect calorimetry repeatedly .Results The mean energy delivery between day 4 and 8 was 28 kcal? kg -1 ? d-1 for the EN plus SPN group ,compared with 20 kcal?kg -1 ?d-1 for the EN group .Between days 9 and 28 ,the EN plus SPN group had a lower incidence of nosocomial infection com‐pared with EN group (P<0 .05) ,the mechanical ventilation time of the patients without nosocomial infection in EN plus SPN group was significantly lower than that of the EN group (P<0 .05) .The in-hospital mortality and the in-ICU mortality were similar in the two groups(P>0 .05) .Conclusion Individually optimized nutritional supplementation with enteral nutrition plus supplemen‐tal parenteral nutrition starting 4 days after ICU admission could reduce nosocomial infections and should be considered as a strate‐gy to improve clinical outcome in patients in the ICU for whom EN is insufficient .

Objective To investigate the impact of propofol and midazolam on the time course of extubation in patients with mechanical ventilation.Methods The patients were randomly divided into the propofol group(n=37)and the midazolam group(n=52),which were further divided into three sedation stratums.The administration of two drugs were stoped immediately while weaning from the ventilator.The awakening time and extubation time of the two groups were recorded and compared with each other.Results Both awakening time and extubation time of the propofol groups were shorter than those of the midazolam group(P

The transvaginal ultrasonography,sonohyterography and intravenous contrast-enhanced ultrasonography are main ultrasonographic methods in evaluation of endometrial lesions.This article introduces the procedures,limitations,advantages and disadvantages of these three ultrasonographic methods in differential diagnosis of benign and malignant endometrial lesions in postmenopausal women.

OBJECTIVE:To observe the effect of cefoperazone on the surgical haemostastic outcome so as to offer reference for preoperative anti-infection medication.METHODS:A total of 60 patients undergoing laparotomy were randomly divided into medication group(cefoperazone)or control group.The blood coagulation functional parameter changes of the 2 groups before and after operation were observed,and the intraoperative blood loss volume,blood infusion volume,and the haemostatic time were recorded.RESULTS:The thrombin time,the prothrombin time,partial prothrombin time were all longer,and the intraoperative blood loss volume and blood infusion volume and the haemostatic time were all more in cefoperazone-treated group than in control group(P

Aim To investigate the antagonistic action o f total saponins of panaxnotoginseng(PNS) on cardiac hypertrophy and its nervous mechanism.Methods (1)cardiac hypertrophy of rats due to pressure overload was induced by constricting of abdominal aorta. There were five groups in the experiments. The rats in Group A(control group)were sham operated . Group B was aorta-constricted group.The rats in Group C,D,E were given ip PNS 50,100,150 mg?kg?d -1 for three weeks respectively. Three weeks later, We measured the heart-weight(HW),left ventricular weight(LVW), the ratio of HW/BW,LVW/BW (LVI) and the cardiomyocyte diameters(MD) after dyeing by HE color.(2)The effects of PNS on the fast excitatory postsynaptic potential(f-EPSP),membrane depolarization induced by application of acetylcholine (ACh),membrane potential and membrane resistance of the isolated Stellate ganglion(SG)of the rats were investigated by means of intracellular recording techniques. Results (1)HW/BW, LVI and MD of Group E were significantly lower than that of Group B(P0.05).(2)At the concentration of 0.10 ～0.16 g?L -1, PNS reversibly depressed the amplitude of f-EPSP, but the ACh depolarization,membrane potential and membrane resistance were not significantly altered by PNS. Conclusion PNS can prevent cardiac hypertrophy due to pressure overload in rats and this action may underline its inhibitory action on presyn aptic effect of regulating calcium influx.

Tau is a microtubule-associated protein th at can promote micortubulbe polymerization in vitro and can stabilize the asse mbled microtubules. Hyperphosphorylated form of tau comprises the main component of the paired helical filaments and neurofibrillary tangles found in Alzheimer s desease (AD). This paper reviews the functions and the prospects of tau in Al zheimers disease.
