Feedback for teaching refers to the mutual transmission and interaction of various information between teaching and learning in teaching process,and is an inevitable result and objective existence of teaching in which teachers and students participate.Effective feedback for teaching is characterized by timely,comprehensive and authentic.Teachers can continuously modify teaching per formance through the feedback of students;the feedback of teaching by students is reflected in examination performance,which really reflects the idea that teaching benefits teachers as well as students.Clinical comprehensive course of eight-year program students is an important bridge between basic medicine and clinical medicine,and the foundation of teaching clinical medicine.Feedback for teaching was applied in students of academic year 2011 from the Department of Surgery of Clinical College in Pekjing Union Medical College,and teaching approach was adjusted in time,contributing to good teaching effectiveness.

As the ubiquitous nucleic acids recognizing motif, Zinc finger protein play important role in regulation of gene expression. The study of recognization specific will greatly facilitate understanding the delicate interaction of Zinc finger protein and DNA. By the choice of expression vector, the induction and culture conditions, the DNA binding domain of Zif268 was expressed in Escherichia coli partly solubly. The gel mobility shift assay shows that purified DNA binding domain can bind its natural target sequence specifically, which indicates the DNA binding domain remains its DNA binding activity in Escherichia coli. The functional expression of DNA binding domain of Zif268 will greatly facilitate the development of in vivo genetic selection assay for the study of Zinc fingers-DNA interaction.

OBJECTIVETo evaluate the sedative effect of continuous intravenous infusion of midazolam in treating severe dental phobia.
METHODS31 patients with severe dental phobia were enrolled and all of them had good communication with dentists. Two teeth in each patient were assigned to control group and experiment group seperately. The control group received root canal therapy. The experiment group were sedated by intravenous midazolam and received root canal therapy. The treat dependence and behavior therapy efficacy were evaluated. The vital signs and side effects during treatment were noted.
RESULTSContinuous intravenous infusion of midazolam showed a significant good sedative effect on patients with severe dental phobia. There were statistical difference in the Houpt score and the Frankl score between experiment group and control group (z = -4.846, P = 0.000; z = -4.907, P = 0.000). The total dose of midazolam was (9.58 +/- 3.76) mg, and mean infusion rate was (0.28 +/- 0.06) mg x kg(-1) x h(-1). The blood pressure, heart rate and respiration of experiment group were depressed. But these changes didn't interfere with the completion of the whole treatment. No severe side effects were detected.
CONCLUSIONThe single use of midazolam as an intravenous sedation agent has satisfactory effect on patients with severe dental phobia.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Objective To study the influence of fluoride on the expression of osteoprotegerin(OPG) mRNA and protein in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarial of suckling Wistar rats were cultured in vitro in the media supplemented with NaF at a series of doses[O(control), 1,2 and 4 mg/L groups], and OPG mRNA expression and protein were evaluated by RT-PCR and ELISA methods, respectively. Results OPG mRNA expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h and 72 h(F=333.48,808.34,P<0.05). OPG mRNA expression in suckling rat osteoblasts cultured in vitro after exposure to NaF for 48 h at different doses(0.810±0.003, 0.819±0.031 and 0.870±0.044 for 1,2 and 4 mg/L groups, respectively) compared with that of control (0.800±0.040, all P<0.05). OPG mRNA expression further increased for 72 h exposure to NaF(0.933±0.047,1.031±0.051,1.240±0.062 for 1,2 and 4 mg/L, respectively), significantly higher than that of the control (0.805±0.020,all P<0.05) and corresponding groups at 48 h. NaF doses and time exposure exhibited a significant synergistic effect on OPG mRNA expression(F=2004.16, P<0.05). NaF also enhanced OPG protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed only in 4 mg/L group(0.228±0.014,0.277±0.048) and control(0.205±0.012,0.229±0.010) at 48 h and 72 h (P<0.05). In addition, OPG protein expression at 72 h post-exposure was higher than that at 48 h,but there was no synergistic effect between concentration and time(F=1.21,P>0.05). Conclusions The results suggested that NaF could increase OPG mRNA and protein expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

In adipose tissues from sreater omentum of patients with type 2 diabetes,the mRNA and protein expressions of human rearranged immunoglobulin?light chain (HSIGVL) 022 were measured by the fluorescent quantitative RT-PCR and immunohistochemistry respectively.The results showed that mRNA and protein levels of HSIGVL022 were up-regulated in patients with type 2 diabetes.The mRNA level of HSIGVL022 was linearly correlated with insulin resistance index,suggesting that this gene may play a role in the pathogenesis of insulin resistance and type 2 diabetes.

OBJECTIVETo compare the positive rate of antibody to hepatitis C virus (anti-HCV) in sera of patients with severe viral hepatitis between 1984-1990 year and 1997-2003 year.
METHODSSerum anti-HCV was detected by enzyme linked-immunosorbent assay (ELISA). It was detected by the first generation (1st) ELISA (Ortho Co. USA) in 79 cases of severe viral hepatitis during 1984-1990 year, and it was detected by the second generation (2nd) ELISA (Xiamen Xingchuang Co. China) in 251 cases of severe viral hepatitis during 1997-2003 year.
RESULTSThe positive rate of serum anti-HCV was 51.9% detected by the 1st ELISA in 79 cases of severe viral hepatitis during 1984-1990 year, and it was 1.2% detected by the 2nd ELISA in 251 cases of severe hepatitis during 1997-2003 year (chi2 = 133.68, P = 0.001).
CONCLUSIONTo compare with the positive rate of serum antibody to hepatitis C virus in severe viral hepatitis detected by the 1st ELISA, it was lower that detected by the 2nd ELISA
