BACKGROUND: Spiral CT three-dimensional reconstruction has been used to observe the femoral head coverage fate of developmental dislocation of the hip (DDH). However, most of research containing certain observing point, which lack of long-term follow-up and comprehensive analysis. This article wants to fill the gaps.OBJECTIVE: To study changes of femoral head coverage fate in DDH child after 3 years treatment by CT reconstruction. METHODS: Totally 73 patients with unilateral DDH treated by aluminium plate after manual close reduction was selected. Spiral CT scanning of femoral articulation was performed at 1 day before and 12, 24, and 36 months after reduction to measure the femoral head coverage fate changes. The normal hip of patient was served as control.RESULTS AND CONCLUSION: All patients were included in the 42-53 months follow-up. After treatment, the femoral head coverage fate of patients were obviously than that of before treatment (P<0.01), which gradually approach to the normal level in 3 years, the first year after treatment is a key period for acetabulum development.

Objective To investigate and analyze the effect of current doctor-patient relationship on profession recognition of medical students and to make some accommodations for medical education. Methods Questionnaire was conducted among 800 medical students in North Sichuan Medical College concerning the aspects of recognition of doctor-patient relationship,profession recognition and effect of current doctor-patient relationship on profession recognition . Data statistics was done by SPSS 19 . 0 . Differences were analyzed by frequency,chi-square test by α=0.05 standard and Spearman correlation analysis. Results 67.6%(536/793)of the surveyed students thought that the current doctor-patient re-lationship exerted effect on their job concepts. According to the results of Spearman correlation analysis between current doctor-patient relationship(X)and effect of current doctor-patient relationship on future job con-cepts(Y),correlation coefficient was 0 . 088 ,P=0 . 013<0 . 05 . Conclusions Effect of current doctor-patient relationship on profession recognition of medical students results from health care policy, school education and society,therefore,university should improve related education .

Samples of skeletal muscle in forearm were taken from 60 sites in each of 10 normal autopsy subjects (male 7, female 3) between 3 and 69 years of age. The distribution and composition of type I and type II fibers in the muscles of the forearm were studied by histochemical method for myofibrillar ATPase. The results showed that the mean percentage of type I fibers ranged between 45% to 59% in the muscles of the forearm. In general, the slow contracting fibers of the forearm muscles were slightly higer than 50%. In the flexors and extensors of the forearm the respective percentage of type I fibers were 49.8% and 55.3%. The slow contraction fibers of the extensors muscle group showed higher proportion of type I fibers than those of the flexor group and the difference is statistically significant (P

8 oocytes) according to the number of oocytes collected in one ovary. On day of human chorionic gonadotrophin injection, PSV, EDV, PI, RI, S/D of ovarian stromal artery in the ovarian were detected and perifollicular vascularity were graded with color Doppler ultrasonography. Results Not only PSV and EDV of stromal artery but also perifollicular vascularity in low-response group was significantly lower than that of normal-response and high-response groups. PSV and EDV of ovarian stromal artery and perifollicular vascularity were highly interrelated with ovarian response. Conclusions The increase of PSV and EDV of ovarian stromal artery and perifollicular vascilarity indicate the improvement of perfusion in ovary and ovarian response.

Objective To reduce the turnaround time for laboratory diagnosis of bacteremia, the feasibility of rapid identification and susceptibility testing using samples taken directly from positive blood culture bottles was evaluated. Methods The growth of microorganisms in blood culture bottles was screened by the BACTEC 9000 blood culture system. 65 positive blood culture bottles containing gram-negative bacteria were adopted to test. Culture fluid was injected into BD SST vacutainer and centrifuged to pellet blood cells. After collecting required McFarland units, they were cultured on Phoenix 100 NMIC/ID-4(identification-gram-negative bacteria and susceptibility testing) cards using 0.25 McF and 0.5 McF methods respectively. They were also evaluated by the standard method, involving subculture tests from positive blood culture bottles. Results 63 of 65 gram-negative bacteria (96. 9% ) were correctly identified with 0. 25 McF method. 59 of 65 gram-negative bacteria(90.8% ) were correctly identified with 0.5 McF method. For antimicrobial susceptibility testing, the 0.25 McF direct method had an agreement rate more than 94% , the 0.5 McF method was more than 85.7% and direct blood sample KB method was more than 93.8% compared to the standard method. But the overall minor error rate in susceptibility testing of direct blood sample KB method is higher than other methods. Conclusion Applying 0. 25 McF and 0. 5 McF rapid identification and susceptibility test was practical. During to possessing more prominent advantages, laboratory put the 0. 25 McF direct method into practice had a timely, remarkable significance.
