"Clinical Laboratory Diagnosis"is a course of trivial and complicated contents,lacking systematization and consisten- cy.Therefore,the students are not interested in acquiring knowledge eagerly.How to improve the quality and efficiency of teach- ing is concluded as clear focus,constant renewed content and attractive class.

Objective:To investigate the effect and mechanism of total flavonoids of Hedysarum polybotry on induction of differentiation in human leukemia HL-60 cells. Method After the treatment of HL-60 cells with total flavonoids of Hedysarum polybotry, the cell differentiation was detected with NBT reduction method. Cell cycle, CD11b and C-fos were analysed by the flow cytometry. Result The positive rate of NBT reduction and the expression of CD11b were significantly increased. Similar, the expression of C-fos gene was upregulated. The growth of HL-60 cells was arrested at G0/G1 and G2/M phase. Conclusion Total flavonoids of Hedysarum polybotry could induce differentiation of HL-60 cells. Its molecular mechanism might be related to the modulation of gene expressions associated with the proliferation and differentiation, which leads to the inhibition of DNA synthesis.

Objective To follow up the changes of postnatal cardiac sizes and function in infants of mothers with gestational diabetes mellitus (GDM). Methods Eighteen GDM mothers with euglycemia (GDM group) and 24 gestational age-matched normal pregnant women (control group),having prenatal examination and delivered in Women's Hospital of Fudan University from January to August in 2007, received fetal echocardiographic examination in late pregnancy. Infants of these GDM mothers and 24 age-matched healthy infants of normal pregnancy (control group) received sonographic follow up. Cardiac sizes and function were evaluated and compared. Results At birth, there were six (33.3%) infants of large for gestational age (LGA) and 12(66.7%) appropriate for gestational age(AGA) in GDM group, while in the control group, there were two LGA (8. 3%) and 22(91.7%)AGA infants (x2 =3. 840, P= 0. 05). Both the interventricular septum and left ventricular walls in GDM fetuses were thicker than in control fetuses (P ＜ 0.05). No increase in the thickness of ventricular walls was observed till infantile period. However, the end-systolic thickness of left ventricular walls in LGA infants was still larger than in control infants [(4.55 ± 0.37) mm vs (4. 13±0.39)mm, P＜0. 05], and end-diastolic left ventricular long-diameters were also larger [(37. 3±2.3) mm vs (34.6±2.6) mm] (P＜0. 05). In GDM fetuses, the peak velocities of aorta and pulmonary artery and left cardiac output were higher than in the controls (P＜ 0. 01 ), and right/left cardiac outputs ratios were lower (1.198±0.206 vs 1. 430±0. 321, t= -2.668,P=0. 011). Till infantile period, only right/left cardiac outputs ratios in AGA infants of GDM group were larger than in controls (P＜0. 05). GDM fetuses' left atrial shortening fraction and tricuspid E/A ratios were smaller (P＜0. 05). In infantile period, only left atrial shortening fraction in GDM infants was still smaller than in controls (0. 356 ± 0. 040 vs 0. 386 ± 0. 041, t = - 2. 332, P = 0. 025). Left and right ventricular Tei index in GDM fetuses were 0. 482±0. 129 and 0. 414±0. 094, both larger than those of control fetuses (0. 309 ± 0. 074 and 0. 283 ± 0. 072) (t = 5. 075 and 5. 129, P = 0. 000 ). Till infantile period they both became significantly lower and no differences were found among LGA, AGA and control infants. Conclusions The cardiac sizes and function at 2-3 months of age, in infants of GDM mothers with good glucose control, became better than that in uterus.

Objective To study the epidemiologic features of functional bowel disorders (FBD)among medical students and science and engineering students in Zhejiang province,China,and to explore the relationship between psychological factors and FBD.Methods This study was a survey of random sampling based on the Rome Ⅲ Diagnostic Questionnaire ( Rome Ⅲ -DQ) conducted from November 2010 to March 2011.The survey was carried out among medical students and science and engineering students respectively in two universities in Zhejiang province.Symptom Check List 90 ( SCL-90 ) was used for psychological analysis.Results Among 1870 participants,1033 were diagnosed as FBD based on Rome Ⅲ criteria,with an overall incidence of 55.24％.The majority cases were unspecified functional bowel disorder,with an incidence of 26.58％ (497/1870),others were functional constipation 16.95％(317/1870),irritable bowel syndrome 6.90％ ( 129/1870),functional bloating 4.12％ (77/1870) and functional diarrhea 0.70％ (13/1870).The prevalence varied in different genders,majors and grades.In the multivariate analysis,women had a higher risk of any FBD than men [ 68.33％ (617/903) vs 43.02％(416/967) ] except for functional diarrhea; and medical students had a higher risk of any FBD than science and engineering students [ 68.53％ ( 734/1071 ) vs 37.42％ ( 299/799 ) ].Generally higher grade undergraduates had relatively higher risks than lower grade students,especially in medical students.Among the participants with FBD,44.05％ (455/1033) had other functional gastrointestinal disorders.In those overlapped parts,9.00％ ( 93/1033 ) had belching disorders,and 8.23％ ( 85/1033 ) had functional dyspepsia.Students with FBD got higher scores in SCL-90 than healthy students.Conclusions This study revealed a high rate of FBD among college students in Zhejiang province.The prevalence varied in different majors,and female higher than male.Psychological factors also had close relationships with FBD.

Objective To investigate the prevalence of functional dyspepsia (FD) and its relationship with psychological factors in college students of Zhejiang Province. Methods The students of two colleges in Zhejiang Province were selected.The multi-stage stratified random cluster sampling method was conducted.The Rome Ⅲ adult FD diagnosis questionnaire (ROME Ⅲ-DQ) and psychological symptoms self rating scale questionnaire (SCL-90) was applied in the investigation.The data were analyzed by x2 test and t test.Results A total of 1870 college students of Zhejiang Province were surveyed.The prevalence of FD was 5.78％.The prevalence in female was higher than that in male (7.53 ％ vs 4.14 ％,x2 =9.884,P＜0.05).The prevalence in senior students was highest in all grade (x2 =13.83,P＜0.05).In FD subtypes,postprandial distress syndrome was more than epigastric pain syndrome.The functional constipation and functional defecation disorders were most common in the overlap with other functional gastrointestinal disorders. In SCL-90 questionnaire survey,the scores of each factor of FD group were higher than those of the healthy control group.Conclusions The prevalence of FD was high in the college students of Zhejiang Province. The incidence was correlated with psychological factors.

In recent years, many modern spectral databases for complex materials ( such as soil, feed, forensic evidence materials, pharmaceuticals and oils) have been established based on molecular spectroscopy (UV, infrared, near infrared, Raman and fluorescence) both at home and abroad, which are playing more and more important roles in the agricultural and industrial production and science research. Spectral searching method is one of the key technologies to make full use of the molecular spectral database. This paper reviewed the progress in the basic and modified algorithm, strategy and application of molecular spectral searching methods, and put forward the scientific and technological problems that need attention and further research.
