It has aroused extensive concern that how to check for new or after-maintenance medical instruments and keep unqualified instruments out of clinical fields.By analyzing the present situation of medical equipment checking and quality management,main problems are pointed out.The importance of medical measuring and testing is emphasized.It is suggested medical metrology management should be strengthened and the checking procedures should be improved.

Case teaching is one of the important means to improve teaching effect in the process of pharmacology teaching. According to the teaching object, teaching objectives and requirements to build one useful teaching case library about pharmacology, which can be used and shared for a long time, is the premise of case teaching in pharmacology. According to the actual situation of case teach-ing in our university, this study researched and explored the background of case library building, the basic principles of case compilation, the establishment of team, the teacher-led and the student-oriented processes of case building, and the process of sorting and summarizing cases in the case library build-ing, which promotes the reform in the pharmacology case teaching, improves teaching quality, and also provides a reference for other universities or schools and disciplines on teaching case library building.

Objective To evaluate the effects of low molecular weight heparin(LMWH)and heparin-binding epidermal growth factor(HB-EGF)on the biological function of human trophoblast in first trimester.Methods From Feb.2011 to Nov.2011,the trophoblast isolated from human first trimester chorionic villi was cultured in vitro.Based on variation of LMWH concentration,the trophoblast was classified into 0.025 U/ml group,0.25 U/ml group,2.5 U/ml group,25 U/ml group and 250 U/ml group.In the mean time,based on treatment of heparin,the trophoblast was classified into LMWH group (0.25 U/ml),HB-EGF group(10 μg/L),combination group(LMWH at 0.25 U/ml + HB-EGF at 10 μg/L)and add with DMEM as control group.Cell prolferation was assessed by the methyl thiazolyl tetrazolium(MTY)test,which was showed with the mean absorbance as A value.Cell invasion was measured by transwell,which counted the number of cells migrated to the superficies inferia of filter membrane.Cell differentiation was assessed by the concentration of hCG secretion.Results Compared with control group,the trophoblast proliferation and invasion treated by LMWH at 0.025 U/ml did not show significant difference (P ＞ 0.05).When treated by LWMH at 0.25 U/ml and 2.5 U/ml,trophoblast proliferation and invasion was increased significantly(P ＜ 0.05).When LMWH at 25 U/ml and 250 U/ml,it could inhibit trophoblast proliferation and invasion(P ＜ 0.05).When compared with A value of 0.44 ± 0.04 in control group,the increased A value were 0.51 ± 0.05 in LMWH group,0.56 ± 0.04 in HB-EGF group and 0.69 ± 0.06 in combination group(P ＜ 0.05).In the transwell test,the cell number were 511 ± 78 in LMWH group,669 ± 67 in HB-EGF group and 872±64 in combination group,which were significantly higher than 405 ± 67 in control group(P ＜ 0.05),respectively.And the hCG concentration were(7143 ± 649)U/L in LMWH group,(11 762 ± 1059)U/L in HB-EGF group and(11 015 ± 1084)U/L in combination group,which showed statistical difference with(8182 ± 666)U/L in control group(P ＜ 0.05).Conclusion LMWH could modulate trophoblast proliferation,invasion,and differentiation.HB-EGF is one of important factors involved in effects of LMWH on trophoblast function.

Objective To study the relationship between Bcl-2/Bax protein expression and the degree of malignancy of astrocytoma.Methods Bcl-2/Bax protein expression positive rate and apoptotic cell rate were determined using immunohistochemical technique and TUNEL, in 10 normal human brain tissues and 80 human astrocytoma specimens of differently malignant degrees confirmed by pathology separatively. Results Bcl-2/Bax protein positive expression was not found in normal human brain tissues, and apoptotic cell rate was only (0 6?0 1)%. The differences of Bcl-2/Bax protein expression positive rate and apoptotic cell rate were statistically significant in the differently malignant degrees(P

Acute pancreatitis (AP) is activated trypsin-induced pancreatic and its peripheral tissue inflammation caused by their own digestion.The activation in advance of trypsinogen and the inflammation cascade in pancreatic acinar cells are thought to be a key mechanism of the onset and development of AP.Autophagy pathway acting as Ⅱ type of programmed cell death occurs in the early pathological course of AP,blockade of which contributes to aggravating necrosis of acinar cells in AP.This article mainly discussed the recent advances in the understanding of autophagy researches and its function in the mechanism of AP.

To maintain the competitive superiority,the medical english majors should optimize and construct the characteristic curriculum system in order to cultivate high-quality professionals of medical english.Taking the medical english major of Beijing University of Chinese Medicine for an example,this paper discusses the theoretic consideration and practice in constructing the characteristic ‘trinity’ curriculum system of medical english majors,hoping that more attention can be paid to its further development.

Objective To study the prognosis of neonatal hyperthyrotropinemia (HT). Methods Children with HT were followed up regularly to evaluate the growth index, thyroid function and effectiveness of treatment. Results One hundred and ninety-one neonates with serum TSH level of 5.6~10 mU/L at the screening were followed up until 24 months old. Serum TSH gradually returned to normal range in 182 cases. Serum TSH increased to be>10 mU/L in 5 cases who were treated with levothy-roxine sodium. Serum TSH lfuctuated between 5.6 and 10 mU/L in 4 cases who were continually followed up. Among 44 cases of serum TSH at 10~20mU/L, serum TSH gradually returned to normal range after levothyroxine sodium treatment in 38 cases;se-rum TSH increased to>20 mU/L in 7 cases for whom continuous treatment with levothyroxine sodium was required. In 242 cases of HT neonates, 18 cases had received continuous levothyroxine sodium replacement treatment for 2 years and were followed-up continuously. Conclusions Most of the newborns with HT recover within 2 years, while a few develop thyroid dysfunction and require follow-ups.

International communication capabilities of traditional Chinese medicine professionals are closely related to the publicity of Chinese medical culture and know-how.Based on the interview results as well as literature research,this paper discusses the qualification of traditional Chinese medicine professionals and proposes five essential elements constituting their international communication capabilities:knowledge and skills of Chinese medicine,foreign language proficiency,knowledge and skills of international communication,a global perspective as well as personal traits.It is expected that it may contribute to the syllabus design,in-service training and talents cultivation in Chinese medical colleges and universities.

ObjectiveTo investigate the relationship between life meaning and life satisfaction among university students.MethodsTotally 473 university students were investigated with The Purpose In Life Test and Life Satisfaction Scale.Results ( 1 ) The scores of life satisfaction and positive affection in highcr levels of life meaning were significantly higher than those in the lower levels of life meaning( (4.53 ± 1.04)vs(3.38 ± 0.98 ),(2.89 ±0.88)vs(2.04 ± 1.07) ) among the university students(F=27.806,P＜0.01 ; F=13.635,P＜ 0.01 ),however the higher levels of life meaning were significantly lower than the lower levels of life meaning ( ( 1.09 ± 1.12 ) vs ( 2.45 ± 1.41 ) ) in negative affection (F =21.513,P ＜ 0.01 ).( 2 ) The students' life satisfaction was negatively correlated with escape( r=-0.336,P＜0.01 ).The others factors of life meaning were positively correlated with life satisfaction ( r =0.285 ～ 0.380,P ＜ 0.01 ).The negative affection was negatively correlated with life meaning( r =-0.121 ～ -0.335,P ＜ 0.05 ).(3)The escape had significantly negative prediction on life satisfaction and positive affection ( β =-0.133 ～ -0.179,P ＜ 0.05 ).The life of goals and the life of passion had significantly positive prediction on life satisfaction and positive affection ( β =0.170 ～ 0.206,P ＜ 0.05 ).Conclusion Life meaning of the university students is closely related to life satisfaction,the higher levels of life meaning can upgrade individual life satisfaction.
