Objective:To explore the relationship among procrastination behavior,meta -cognitive and emotion of university students.Methods:A total of 468 undergraduates from 4 universities were surveyed by GPS,PANAS and MCQ-30.Results:①The undergraduates from liberal arts colleges reported more procrastination behavior than those from science colleges.② Cognitive confidence,positive beliefs,uncontrollability/danger,tendency to control thoughts,and negative emotion positively correlated to procrastination behavior;cognitive self-consciousness and positively emotion negatively correlated to procrastination behavior.③ Cognitive confidence,uncontrollability/danger and negative emotion could positively predict procrastination behavior.④Negative emotion mediated the relationship between uncontrollability/danger and procrastination behavior.Conclusion:Uncontrollability and danger are a significant predicator of procrastination behavior,and negative emotion has a significant mediation effect on the relationship between uncontrollability/danger and procrastination behavior.

In order to stimulate students to interest in study,broaden their horizons,and strengthen their scientific literacy,the writers opeed the elective course of medical microbiology---《plague and the movie》.During this teaching process the writers explored the setting of the elective course,and summarized the experience and the existing problems of the process and prospect the teaching work of the future.

Interest teaching method aims to inspire students' initiative and inquiry in learning.In the teaching process,we used some teaching methods including class lead-in,relevant extracurricular books and websites,scene representation,lectures on special content and arrangements of the review writing.It is important to maintain students' motivate and interest in learning human parasitology,therefore,we should no longer make students passively accept but the initiatively make inquiry learning.

Metal sulfides are chemically attacked by Fe~ 3+ and H~+, resulting in the formation of elemental sulfur via polysulfides or thiosulfate pathway. Elemental sulfur may aggregate and even form a layer on the metal sulfide surface, which will inhibit leaching metals from the sulfides minerals. Elimination of inert elemental sulfur in a typical acidic environment can exclusively be by way of oxidation of acidophilic sulfur-oxidizing bacteria, such a way includes the attachment, transport and oxidation process of elemental sulfur by acidophilic sulfur-oxidizing bacteria. On the basis of analysis on the pertinent researches, the molecular mechanism of sulfur elimination by the acidophilic bacteria is far away from elucidated, and to attain that target, there are still much work to be done for elucidating the molecular mechanism on the attachment, transport and oxidation process of elemental sulfur by the acidophilic sulfur-oxidizing bacteria.

The key point of study on CO2 removal by microalgae cultured in a photobioreactor is to improve CO2 removal capability. In this paper, a model of air-lift photobioreactor was developed by combination of conditions including the velocity of flow, the degree of mixing, the gas-liquid mass transfer and the rate of photosynthesis, and two corresponding simplified methods, such as time discretization and lumped parameters were put forward. Using a method of lumped parameters, the model for simulation of time course of DO, pH in the column air-lift photobioreactor and prediction of CO2, O2 concentrations in the outlet gas under different CO2 concentration in the aeration gas was thoroughly discussed. Experimental data were also used to verify the model which could potentially be applied to rational design of the photobioreactor, high-density culture of microalgae and efficient removal of CO2.

Objective To investigate the relationship between maintaining concentration and loss of consciousness (LOC) concentration of propofol target controlled infusion (TCI) in patients undergoing heart valve replacement.Methods Thirty patients undergoing elective heart valve replacement were enrolled to receive propofol by ladder plasma TCI for anesthesia induction,8 males and 22 females.The initial plasma concentration (Cp) of propofol was set to 1.0 μg/ml,0.3 μg/ml Cp was increased every 1 min until LOC when the prediction effect-cite concentration (Ce) reached 0.5 μg/ml,then sufentanil 0.8-1.0 μg/kg and rocuronium 0.6-0.9 mg/kg were given for intubation.When BIS reached 50,Cp was decreased to the level of Ce.All the surgeries were performed under hypothermia CPB.MAP,HR,CVP,CO,SV,SVR,BIS,propofol Cp and Ce values were recorded at baseline (T0),LOC (T1),BIS reached 50 (T2),and other time points during operation (T3-T9).The correlation analysis between propofol Ce at LOC and perioperative variables were completed.Results In correlation analysis,there was a significant positive correlation between propofol Ce at LOC and baseline CO,SV (P<0.01),there was a significant negative correlation between propofol Ce at LOC and age (P<0.05),there was a significant positive correlation between propofol Ce at LOC and propofol Ce at T2-T9(P<0.01).Conclusion In patients undergoing valvular replacement,the Ce of propofol at maintenance are related to the concentration of propofol at LOC,which is helpful for adjusting the Ce of propofol at maintenance according to the Ce of propofol at LOC.

OBJECTIVE:To explore the role of clinical pharmacist in the therapy for patient with community-acquired Pseudo-monas aeruginosa lung abscess. METHODS:Clinical pharmacist participated in the therapy for a patient with community-acquired P. aeruginosa lung abscess,analyzed anti-infective therapy plan,and adjusted drug use timely to correct agranulocytosis induced by anti-infective drugs. RESULTS:The physicians adopted the suggestions of clinical pharmacists,controlled the infection successful-ly and corrected agranulocytosis. CONCLUSIONS:Community-acquired P. aeruginosa lung abscess is rare but has high mortality. Clinical pharmacists participate in drug therapy,assist physician to improve and optimize therapy plan and formulate individual medication plan so as to promote promote care rate of patients.

Objective To investigated the serum level of carcinoma antigen 125 (CA-125) and its clinical significance in patients with Budd-Chiari syndrome.Methods We reviewed medical records and laboratory tests of patients with BCS first diagnosed in our hospital between August 2011 and April 2013.235 patients were included as experiment group,while 120 healthy adult volunteers were randomly selected as control group.The serum level of CA-125 were detected by electrochemilumescence immunization assay in this single-center retrospective control study.Results The average serum level of CA-125 in experiment group is higher than that of control group [(147.9 ±246.6) kU/L vs (16.0 ±7.2) kU/L,P ＜0.001].In experiment group,the relative coefficient for serum CA-125 with ascites,alanine aminotransferase,aspartate aminotransferase,albumin and Rotterdam BCS scores was 0.79,0.45,0.29,-0.393 and 0.71,respec tively,P ＜0.001.As of October 2013,we found that the 68 BCS patients with serum CA-125 level 5-fold higher than the upper limit of normal (＞ 175 kU/L) presented much lower survival rates and asymptomatic survival rates than the rest 167 BCS patients after intervention therapy:(95.6％ and 79.8％) vs (98.8％ and 92.0％),P ＜ 0.05.Conclusions The serum level of CA-125 in BCS patients have positive correlation with ascites volume,liver injury degree and Rotterdam BCS scores.Serum CA-125 evaluation appears to be a valuable examination option in BCS as CA-125 levels negatively correlate with worse prognosis,thus could be applied as an efficient tool for prognostication.

Objective To evaluate the effects of the range and the frequency of the compression load on the accuracy for discerning target stiffness differences in ultrasound elastography.Methods Quantitative ultrasound elastography was achieved by integrating two compression force sensors,a laptop computer and a clinical ultrasound elastographic system.The force sensors and the ultrasound probe were assembled in a 3D printed mounting bracket for continuous monitoring of compression loads during ultrasound elastography. Both the force measurements and the elastographic maps were acquired and displayed on the laptop computer in real time.Four targets of the same diameter(10.4 mm),the same depth (3 cm) and different stiffness levels (8,14,45 and 80 kPa) were examined by a HITACHI preirus,L74M linear-array transducer.Each target was evaluated 45 times with two different method(i.e.,freehand elastography and quantitative elastography),yielding 1 80 evaluations.The data were divided into the following three groups:group Ⅰ(80 kPa vs 45,14 and 8 kPa),group Ⅱ(80,45kPa vs 14,8 kPa)and group Ⅲ(80,45 and 14 kPa vs 8 kPa).Area under ROC curves(AUC)were calculated for different stiffness levels.Results In group Ⅲ, quantitative elastography yielded an greater AUC level than that of freehand elastography(P =0.0379).In group Ⅰ and group Ⅱ,two methods yielded the similar AUC levels (P = 1 .000).However,quantitative elastography was able to discern 8 kPa and 14 kPa targets (P <0.001),while freehand elastography was hard to differentiate them(P =0.258).Conclusions In comparison with freehand elastography,quantitative ultrasound elastography is able to improve the accuracy for discerning different target stiffnesses.
