With the development of magnetic resonance (MR) technology, the concern is focused on molecular and physiological imaging besides structural information. Ultra high field MR scanner shows great superiority. 3. 0-T MR scanners provide almost two-fold signal-to-noise ratio (SNR) compared with a standard 1. 5-T MR scanner. The higher baseline SNR can be converted into a variety of alternative benefits. There are still some other changes brought about by 3. 0-T, such as higher sensitivity to motion, susceptibility effect, more difference in resonant frequency among different metabolites, and so on. These features may be a double-edged sword in structural and functional imaging. But with the ceaseless progress of the technology and gains in experience, 3. 0-T systems will provide more information and show more advantages.

Objective To investigate the diagnostic value of serum soluble transferrin receptor(sTfR) in children with iron deficiency anemia(IDA).Methods Sixty-three children with microcytic hypochromic anemia were divided into IDA and non-IDA(n-IDA)groups,on which sTfR and other iron metabolism related indexes such as serum ferritin(SF) and serum iron(SI) were measured,and(t-test) between groups and analysis of ROC curve were carried out.Results The mean concentration of sTfR in the group of IDA was above normal value and t-test difference was extremely significant compared with n-IDA group(P

Objective To investigate the necessary and feasibility of fistulous tissue-saving anorectoplasty for low anorectal malformation with fistula in children.Methods The clinical data of 67 cases of low anorectal malformation with fistula were analyzed retrospectively, there were 59 girls with rectovestibular fistula, 8 boys with rectoperineal fistula. The patients′ average age were 10 months, ran -ging from 3 months to 16 years. The clinical manifestations of all patients were intractable constipation, or out of position of anus. Cut-back procedure had been performed on 4 patients in infancy. The anterior sagittal anorectoplasty was performed in all cases.Results In all cases returned for follow-up at 3 and 6 months after operation, the longest was 8 years. The postoperative course of 65 patiens was uneventful without wound infection, and had a normal-looking perineum, other 2 cases with anal rupture in operation were with sagittal wound infection resulted from perforation in repairing anus, and formed finally rectoperineal fistula with a normal-looking anus. Sixty-four cases (95.5%) had good continence by 5-6 score, another 3 cases (1 boy, 2 girls) with intractable constipation defecated with help of Glycerinum.Conclusions The fistulous tissue-saving anterior sagittal anorectoplasty is a reliable and feasible procedure for low anorectal malformation with fistula. This operation provides good results.

Objective To explore therapeutic effect and side effect of oral indomethacin for treating patent ductus arteriosus(PDA)in full-term infants.Methods Forty-one full-term infants confirmed PDA by echocardiographically,who were admitted to the neonatal intensive care unit of our hospital from Jan.2004 to Dec.2007,were randomly divided into experimental group(21 cases)and control group(20 cases).Three oral doses of indomethacin [0.2 mg/(kg?time),at an interval of 12 hours] were administered in experimental group,while nothing in control group.Hepatorenal function and blood routine were measured in both groups in 2 days before and after treatment.Urine output and level of serum blood sugar were measured,and abdominal distension,vomiting,bloating,and bleeding were recorded during treatment.Color Doppler echocardiographic examination was performed,heart murmur was stethoscopied,and the rate of ductal closure was recorded at 5 to 7 days after treatment.The infants were followed up at out-patient department at 6 to 12 months after treatment,color Doppler echocardiographic examination was performed,and ductal closure condition was recorded.Results Hepatorenal function and blood routine were normal in experimental group in 2 days before and after treatment.Except that a little gastrointestinal bleeding occurred in one case of experimental group after the second dose of indomethacin,other adverse reactions were not observed during treatment.The ductus was closed in 16 infants in experimental group,the rate of ductal closure was 76.19%,while the ductus was closed naturally in 5 infants in control group,the rate of ductal closure was 25.0% at 5 to 7 days after treatment.There was significant difference in the rate of ductal closure between the experimental and control groups(?2=10.74 P

Objective To provide histological evidence for clinic tendon reconstruction on severe medial collateral ligament injury in rabbits. Methods Medial collateral ligaments of two knee joints were completely incised to create own control model of MCL rupture. The operation group intimated the procedure of human being MCL reconstruction with semitendinous tendon. In the 4th,12th,16th,24th weeks, healing of MCL was observed by anatomy and the picrosirius-polarization method. Results In the 4th week, the MCL healing tissue of ex-periment group is more than control group. The average ratios of type Ⅲ collagen to Ⅰ, Ⅲ collagen in the experiment group [(0.263±0.075), (0.235±0.041), (0.210±0.045), (0.197±0.029)] were significantly lower than those in control group [(0.310±0.072), (0.286±0.045), (0.261±0.046), (0.236±0.043) ] in the 4th, 12th, 16th, 24th weeks, respectively (P < 0.05). Conclusions The semitendinons tendon reconstruction can improve MCL healing in early and middle period after injury.

Objective To investigate the efficacy of ultrashort and short-acting insulin after subcutaneous insulin infusion pump under glucose monitoring in treatment of diabetes.Methods 110 cases with type 2 diabetes were selected,they were randomly divided into two groups with a random number table:the study group and the control group,55 cases in each group.The study group was treated with short -acting insulin after subcutaneous injection of insulin pump,the control group was treated with short -acting subcutaneous insulin infusion by insulin pump therapy, glucose monitoring system was used to monitor glucose during treatment of the two groups.The clinical efficacy after a month of treatment was observed.Results Before treatment,fasting blood glucose(FPG),postprandial 2 h blood glucose(2h PG),bedtime blood glucose of the two groups had no statistically significant differences.After treatment, FPG and 2hPG,bedtime blood glucose in the study group were (6.01 ±1.06)mmol/L,(7.90 ±0.50)mmol/L, (7.13 ±0.95)mmol/L respectively,which of the control group were (5.98 ±1.04)mmol/L,(7.91 ±0.48)mmol/L, (7.14 ±0.94)mmol/L,which were significantly lower than before treatment (t =9.843,23.669,13.569,9.683, 22.881,13.710,P <0.05),the two groups after treatment showed no significant differences(P >0.05).The blood glucose time and insulin dosage in the study group were (5.59 ±1.30)d,(39.98 ±11.01)u/d,which of the control group were (6.98 ±1.40)d,(51.89 ±11.97)u/d,and there were significant differences between the two groups(t =1.825,5.431,P <0.05).The mean blood glucose,blood glucose standard deviation,time percentage of blood glucose≥10 mmol/L,time percentage of blood glucose≤3.9 mmol/L in the study group were (5.95 ±0.61 )mmol/L, (1.28 ±0.25)mmol/L,(14.16 ±2.13)%,(6.35 ±1.45)%,which in the control group were (6.59 ±0.94)mmol/L, (1.54 ±0.29)mmol/L,(15.15 ±2.14)%,(7.96 ±1.42)% respectively,and the differences were statistically significant between the two groups(t =4.236,503.6,2.432,5.883,P <0.05).Conclusion Glucose monitoring system in monitoring blood glucose is accurate and reliable,ultra -short -acting insulin after subcutaneous insulin pump infusion in treatment of diabetes is better than short -acting insulin.
