Mobile learning behaviors are the greatly concerned hotspot in educational field.However, the specific mobile learning behaviors of university undergraduates are not subdivided in the current researches.The mobile learning behavior data of university undergraduates in different learning circumstances were recorded by literature survey, interview and questionnaire investigation, the characteristics of mobile learning behaviors were subdivided and analyzed in order to help them work out their strategy for mobile learning in different learning circumstances, which showed that the frequency of intelligent mobile learning was higher than that of traditional mobile learning in specific academic activities (academic exchange, self learning, academic sharing, transmission and search), and that the new generation of digital young people showed their preference to mobile learning due to its advantage of convenience while the disadvantage of its function and operation limited its persistent use.It is thus the hope of university undergraduates, especially medical undergraduates, to develop more devices and tools that are convenient for their mobile learning by making use of the advantages of intelligent mobile terminal and traditional terminals.

BACKGROUND: The mental health of primary school teachers who have been working in remote mountain areas for a long time can be affected by the environment and conditions there.OBJECTIVE: To analyze the present mental health of mountain-area teachers to seek countermeasures of raising their mental health level.DESIGN: An investigation of random sampling questionnaires was carried out with the primary school teachers in remote mountain areas as observational subjects.SETTING: Department of Education, Xinzhou Teachers' Training Institute.PARTICIPANTS: From December 2003 to February 2004, 182 teachers who were randomly sampled from the 28 most remote mountain schools selected from seven counties and cities such as Wutai, Shenchi and Hequ in Shanxi Province, were selected as investigation subjects.METHODS: The self-assessed/measured symptom scale was used to assess the mental health of mountain area teachers. The scale was made up of 90 items, including 9 factors such as somatic disorder, obsessive disorder, interpersonal sensitivity, anxiety, depression, hostility, horror, paranoia,and psychoticism. There were 5 scaling levels: 1 shows 'never', 2 shows'mild', 3 shows 'moderate', 4 shows 'rather serious' and 5 shows 'severe'. Evaluation standard: If the factor score ≥ 2, they had mild symptoms; if any factor score ≥ 3, they were regarded as probably having mental problems above moderate degree. The major statistical indexes were the 9 factor scores, detection rate of moderate pain (factor score ≥ 3) and positive item number (factor score ≥ 2), all of which were compared with the national normal norm.MAIN OUTCOME MEASURES: The mental health of male/female teachers and teachers of different ages in mountain areas.RESULTS: Totally 182 copies of questionnaire were distributed, and 146of them were collected, with an effective rate of 80.2%. ① The total detection rate of psychological problems was 51.7%, in which male teachers made up 48.8% while female teachers 53.3%. Those with psychological problems above moderate level constituted 6.1%, of which male teachers held 1.4% and female teachers held 4.8%. The detection rate of each psychological problem among teachers of mountain areas ranged from2.1% to 12.3%. The symptoms ranked in detection rate from high to low were obsessive disorder, anxiety, interpersonal sensitivity, depression, somatic symptom, psychoticism, paranoia, horror and hostility. ② The total score and total average score of self-assessed/measured symptom inventory of mountain area teachers were obviously higher than those of the normal norm. The number of positive items was smaller than that of the normal norm, but the average score of positive items was obviously higher than that of the normal norm. It showed that the level of mental health of mountain area teachers was generally lower than that of normal population in the nation. ③ All the factor scores on the self-assessed/measured symptom inventory of mountain area teachers were obviously higher than the level of national normal population (P ≤ 0.01). ④The number and average score of positive items of mountain area female teachers were higher than those of the male teachers. The factor scores on interpersonal sensitivity, depression and anxiety of the female teachers were higher than those of the male teachers with significant difference (P ≤ 0.05). ⑤The average score of positive items and the score of the factors such as somatic symptom and horror of the teachers aged ≥ 30 years old were significantly higher than those of the teachers aged under 30 years old (P≤ 0.01).CONCLUSION: The detection rate of psychological problems of mountain area teachers was relatively higher, which were mainly presented as obsessive disorder, interpersonal sensitivity, anxiety, depression, and somatic symptom. On the self-assessed/measured symptom inventory of the mountain area teachers, the total score, the total average score, the average score of positive items and the score of each factor were obviously higher than those of the national normal population. The incidence rate of psychological problems of the female teachers was higherthan that of the male teachers. The mental health leve1 of teachers aged 30 years old or above was relatively lower.

OBJECTIVE:To compare clinical efficacy and safety of budesonide and beclometasone assisting with terbutaline by atomization inhalation in the treatment of acute pediatric asthma attack. METHODS:150 pediatric patients with acute asthma attack were randomly divided into group A and group B,with 75 cases in each group. Both group received symptomatic support treatment as low-flow oxygen inhalation,eliminating phlegm,relieving a cough,dilating bronchus and anti-infection,and atomization inhala-tion of budesonide,1 ml each time,bid. Based on this,group A was given atomization inhalation of budesonide,2 ml each time, bid;group B was given atomization inhalation of beclometasone,2 ml,bid. Treatment course of 2 groups lasted for 7 d. Clini-cal efficacy,asthma control,PEF% and the occurrence of ADR were observed in 2 groups;the time of symptoms and signs dis-appearance and hospitalization time were recorded,and symptoms and signs of children were scored 1 day before treatment and 7 days after treatment. RESULTS:During treatment,2 cases and 3 cases were withdraw from the test in group A and group B, respectively. The total effective rates of group A and B were 91.78% and 94.44%,and the rate of asthma control 95.89% and 94.44%,without statistical significance(P>0.05). The time of breathing difficulties disappearance,cough disappearance time, wheezing disappearance time and hospitalization time of group A were separately (2.11 ± 0.54),(3.28 ± 0.93),(4.38 ± 1.05), (5.83±1.29)d;those of B group were separately(2.07±0.52),(3.30±0.96),(4.45±1.08),(5.90±1.33)d,there was no sig-nificant difference between 2 groups(P>0.05). The clinical symptoms and signs score of group A before and after treatment were separately (4.28 ± 0.94) and (0.15 ± 0.04);those of before and after treatment of group B were separately (4.23 ± 0.91) and(0.11±0.03). There was significant difference before and after treatment(P<0.05),but there was no significant difference between 2 groups (P>0.05). The PEF% of group A before and after treatment were separately (51.4 ± 9.8)% and (67.2 ± 11.2)%;those of before and after treatment of group B were separately(52.0±7.1)%and(68.3±8.7)%. There was significant difference before and after treatment (P<0.05),but there was no significant difference between 2 groups (P>0.05). No obvi-ous ADR was found in 2 groups. CONCLUSIONS:Budesonide and beclometasone assisting with terbutaline by atomization inha-lation in the treatment for acute pediatric asthma attack possess the same effects and can efficiently relieve symptoms and signs, increase the rate of asthma control and shorten the rehabilita-tion course with good safety.

In order to obtain experimental evidences of therapeutic effect of rhIL 11 for clinical use, we observed the effects of rhIL 11 on colony formation of multilineage human hematopoietic cells in vitro and acceleration of platelet count and bone marrow hematopoietic recovery in 3 0Gy ? ray irradiated rhesus monkeys. The results showed that rhIL 11 significantly increased the nadirs of PLT count and shortened the duration of PLT numbers below 50% of their baseline values. The recovery of PLT in irradiated monkeys was accelerated. Dosage related PLT recovery was not observed. rhIL 11 not only promoted the proliferation and maturation of CFU Mk but also improved the proliferation of CFU GM, CFU e, BFU e and CFU Mix. These data suggest that rhIL 11 may be an effective agent in the treatment of hemopoietic suppression and thrombocytopenia.

A high-throughput method for screening drug multi residues was developed by quadrupole-time-of-flight( Q-TOF) mass spectrometry together with QuEChERS sample preparation technique. It has been used for the determination of 57 drugs, such as tetracyclines ( TCs ) , sulfonamides ( SAs ) , quinolones ( QNs ) , triphenylmethanes (TPMs), estrogens (ETs), androgens (AGs) and glucocorticoids (GCs) in fish. The optimized pretreatment conditions were examined. The target compounds were extracted with acetonitrile under the condition of Na2 EDTA-Mcllvaine buffer, and the usage of clean-up reagents was 25 mg anhydrous magnesium sulfate, 12. 5 mg octadecylsilane and 6. 25 mg N-Propylethylenediamine sorbent for extracted solvent of each milliliter. The positive results acquired by this high-throughput method were confirmed by liquid chromatography-tandem mass spectrometry ( LC-MS/MS) . The detection limit for these 59 drugs was in the range of 0. 5-5. 3 μg/kg. The method is time-saving, convenient, effective and wide coverage. Its sensitivity can meet the requirement of the detection of drug residues in aquatic products.
