Objective: To study the spatiotemporal expression pattern of histone acetyltransferase steroid receptor coactivator-1 (SRC1) in developing mouse heart, so as to explore the relationship of SRC1 with heart development. Methods: The normal mouse hearts were collected at E7.5-E18 and 1 day and 3 months after birth; 9 specimens were chosen for each time point to observe the spatial expression of SRC1 by immunohistochemistry technique, and 6 specimens of each time point were used to examine the temporal expression of SRC1 protein by Western blotting technique and to plot the time-dose curve. Results Immunohistochemistry showed no expression of SRC1 in the heart primordium at E7.5; only very weak SRC1 expression was found in the cardiac tube at E8. 5-E9.5. Weak SRC1 expression was found in the trabeculae after E10.5 and relatively strong and widespread expression was found in other heart regions. Western blotting results demonstrated that SRC1 protein expression at E10.5 was significantly lower than those at E11.5 and E12.5 (P<0.05), and was not significantly different with those of other time points after ElO. 5 (P>0.05). SRC1 expression reached the peak at E11. 5-E12.5, and there was no significant difference between the two time points (P>0.05). SRC1 expression gradually decreased after Ell. 5-E12.5 till the adulthood, and there were no significant differences in the expression after E13.5 (P>0.05). Conclusion: Widespread distribution of SRCl is present in the developing mouse heart after ES. 5, and the expression is in a dynamical spatiotemporal pattern, suggesting that SRC1 may take part in the overall regulation of the heart development, and it might has a closer relationship with the early induction of the heart septa.

Objective To draw up the Chinese Words Reading Test and try to use it as way of premorbid intelligence. Methods 373 health middle-elderly people as study subjects, from five communities in Shanghai city, are between age 55 and 85, and their edueational background is junior high school or above, and their MMSE scores are more than 24 points. 34 of the cases have finished CWRT and Weehsler Adult Intelligence Scale (WAIS) Chinese Revised edition. The main analysis indicators of CWRT: CWRT-Ⅰ for number of right reading 50 characters and CWRT-Ⅱ for 50 words. Results Both CWRT-Ⅰ and CWRT-Ⅱ are relative to education level( r = 0.462,0.489, and P < 0.01), while the correlation with age is not signifieant. Performance of the male participants are better than that of the female. The coefficient of correlation between scores of CWRT-Ⅰ and full IQ of WAIS is 0.79. The mean and standard deviation of scores of CWRT-Ⅰ and CWRT-Ⅱ for the normal elder people with different education levels and gender are provided. Conclusion CWRT is not very diffieuh or easy, and is highly relative to score of WAIS. So it can be used as an evaluating tool for premorbid intelligence.

Objective To study the influence of dietary test designed by Nutritional Department of Henan Provincial People's Hospital on diabetic inpatients' dietary cognition. Methods A total of 134 diabetic inpatients were selected and tested with standard diabetic meaL Self-reporting of oil, salt, staple food, vegetables and meat intake was evaluated. Nonparametric tests were used for statistical analysis. Results There were significant differences in self-reporting of oil,salt,staple food and meat intake between pre and post test (Z= -4.642, -8.700, -2.218, -5. 528,all P<0.05) ; however,no significant change of self reporting vegetable intake was found ( Z = - 1. 385, P > 0. 05 ). Conclusion Dietary test can significantly change patients' cognition about their daily dietary intake.

Objective:To compare the cognitive functions between elderly of Shanghai, Hong Kong and San Diego.Method:104 elderly in Shanghai was evaluated by the Chinese version of Mattis Dementia Rating Scale (DRS)and mini-mental state examination (MMSE), the results were compared with that of 104 persons in Hong Kong and 150 elderly participants in San Diago.Result:Compared with Hong Kong participants, Shanghai participants performed significantly higher on one item, but there were significantly differences in five items between Shanghai participants and the San Diego participants which age and education were matched.Conclusion:Some DRS subscales or individual items may be susceptible to cultural differences.

Objective To evaluate the soft tissue profile in adults with unoperated isolated cleft palate. Methods Twenty patients older than 16 years(median age,18.4) with unoperated isolated cleft palate were enrolled.Soft tissue lateral cephalograms were traced and compared with those of cleft operated patients and class-Ⅰocclusion individuals.The results of various measurements were analyzed with ANOVA by SPSS11.5. Results In adults with unoperated isolated cleft palate,there was restriction at the top of the upper lip,and the antelabrum of upper lip and the lower lip were found normal. Conclusion The soft tissue profile in adults with unoperated isolated cleft palate exhibits almost the same characteristics as the corresponding hard tissue,and there is covering over effect of the soft tissue to some extent.

Objective To explore the mid-term efficacy of biological type,long-stem artificial caput femo-ris replacement operation in the treatment of unstable senile intertrochanteric fracture.Methods 73 patients accepted the treatment of biological type long-stem artificial caput femoris replacement operation,and 64 cases were followed. After 3 months of operation,these 64 patients were divided into four groups which marked as A,B,C and D according to the Berg balance scale(BBS).Accordingly,54 patients that in grade A,B and C would be brought into in long-term follow-up study.54 cases include 25 male patients and 29 female patients with an average age of 81.6 years old who aged from 73 to 94 years old.According to Evans-Jensen classification,28 cases were Evans-JensenⅡand the left 26 cases were Evans -JensenⅢ.Results The follow-up period was in the range of 24 to78 months (mean 42months).During this period,except the 9 death cases,there was no case of femoral trochanteric ununited fracture, femoral prostheses loosening or dislocation of hip joint.In total,3 cases occurred with loss of fixing wire,4 cases occurred with acetabular wear,one case was experienced prosthesis adjacent fracture and three cases of heterotopic ossification.According to the Engh standard,all femoral prostheses got osseous fixation.The rate of excellent and good result were 88.9%with in which excellent in 23 cases and good in 17 cases.Conclusion The application of biological type long-stem artificial caput femoris replacement in the treatment of unstable senile intertrochanteric fracture can achieve satisfactory mid-term efficiency.

Objective To discuss the short-term outcomes of uncemented APL stem hip hemiarthroplasty for unstable intertrochanteric fracture in elderly patients.Methods From July 2008 to December 2011,26 cases of intertrochanteric fractures were treated by hemiarthroplasty using uncemented APL stem.There were 10 men and 16 women with a mean age of 82.5 years (range,75-94 years).According to EvansJensen classification system,16 cases were type Ⅱ fractures,the other 10 were type Ⅲ.Results The mean operation time was 56 min (range,48 to 72 min).The average blood loss during the operation was 360 ml (range,240-600 ml).One of the patients died in the perioperative period,2 died during the follow-up.The other 23 patients were followed up with an average of 21.5 months (range,12-42 months).The patients were encouraged to walk with aid about 2-3 weeks postoperatively.Three months after the operation,the walking ability were almost recovered to pre-injury level in 21 cases.The acetabular wear,the prosthetic loosening and subsidence were not found.The complications included 1 case of cerebral infarction,1 case of deep venous thrombosis,2 urinary infection,1 skin ulcer due to the long-term use of cortical steroid and 2 heterotopic ossifications.According to Harris hip score,12 cases were classified as excellent,10 cases as good and 1 case as fair.Conclusion Hemiarthroplasty using uncemented APL stem is an effective way to treat the unstable intertrochanteric fracture in elderly patients.The quality of life of the elderly patients can be improved due to early mobilization after the surgery.
