Conclusion Prenatal ultrasound screening for fetal congenital anal atresia can be detected.But for lacking of specific diagnostic standard,the detection rate of anal atresia remains very low.

Objective To stuay CT findings of adrenal gland trauma(AGT).Methods The CT images of adrenal gland trauma which were found in 1712 patients who had emergency abdominal CT examinations for assessment of blunt force trauma were analyzed restrospectively.Results Among 1712 cases.we identified 29 patients(1.7%)with adrenal gland traumatic lesions.A total of 32 lesions were found.Twenty-six lesions were unilateral(23 right-sided,3 left-sided),and 3 cases were bilateral(6 lesions).Main CT findings were as followed:(1)Adrenal hematomas appeared as discrete round or oval masses expanding the adrenal gland in 22 patients with 25 lesions.The lesions were hyperdense or of homogeneous density in plain scan and did not enhance in three-phase contrast-enhanced dynamic scan.The splayed adrenal limbs around hematoma were enhanced significantly as eurvilinear structures.(2)Mild to moderate uniform swelling of gland was shown in 4 cases.(3)Diffuse irregular hemorrhage obliterating the gland was shown in 3 cases.Contrast extravasation was shown in 1 case,which was active bleeding from the broken adrenal gland proven by operation.Associated CT findings included strand-like hemorrhage of the periadrenal fat and posterior pararenal hemorrhage mimicking thickened diaphragmatic crus.The concurrent injuries of ipsilateral thorax or/and abdomen were found in 25 patients.Conclusion The AGT has typical CT findings.Familiarity with characteristic CT findings of adrenal trauma is essential for the radiologist to avoid misdiagnosis.

Objective To explore the cosmetic effect of oncoplastic volume displacement in breastconserving surgery.Methods 43 cases of breast cancer in stages I and Ⅱ with pathological diagnosis by core needle biopsy were operated by extended resection of tumor combined with axillary lymph nodes dissection.Among the patients,wound cavity was repaired by direct skin suture without suture of mammary gland deletion in 22 cases,and another 21 cases were repaired by oncoplastic volume displacement technique in which skin suture followed by freeing remaining breast tissue flap and translocation to repair the mammary defect.All of them were treated with three-dimension conformal radiotherapy,standard chemotherapy and endocrine therapy after operation.3 years after partial removal of breast,a retrospective historical control study had been fulfilled to analyze breast cosmetic results between two groups.Results In direct suture group,the cosmetology score was 4.3 points and fine rate was 40.9% (9/22).In breast reconstruction group.the score was 4.8 points and fine rate was 71.4% (15/21).The breast cosmetic effect in breast reconstruction group was significantly better than that in direct suture group (P<0.01).Conclusion It will get better breast cosmetic results after operation to utilize oncoplastic volume displacement suture technique in breast-conserving surgery.

Objective To investigate the difference of the expression of hypoxia reaction genes of vascular endothelial growth factor(VEGF),erythropoietin (EPO) and hypoxia-inducible factor-1 alpha (HIF-1α)) at different times of rats that were induced epilepsy by kainic acid (KA),and analyze their correlation.Methods The epileptic rat model was established by intraperitoneal injection of kanic acid.The expression of VEGF,EPO and HIF-1α gene were detected by real-time fluorescent quantitative PCR assay with TaqMan probe in different times after intraperitoneal injection of KA.Results Compared with normal sodium (NS) group,the expression VEGF was higher at 12 h((8.38±1.27) ×10-3 ng/μl,P＜0.05)) and 24 h((8.30±5.08) ×10-3 ng/μl,P＜0.05)),EPO was higher at 12 h((8.42±0.90) × 10-5 ng/μl,P＜0.05)) and 48 h ((1.50±3.25) × 10-2 ng/μl,P＜0.01)) while the HIF-1α was higher at 24 h((2.11±0.21) × 10-2 ng/μl,P＜0.01)),48 h((1.50±0.33) × 10-2 ng/μl,P＜0.05))and 72 h((1.64±0.16) × 10-2 ng/μl,P＜0.01)).Furthermore,the expression of EPO showed significant correlations with HIF-1α and VEGF (r=0.573,0.471,P＜0.05),VEGF and HIF-1α had eminent correlations (r=0.803,P＜0.01).Conclusions The expression of VEGF,EPO and HIF-1α participate in the seizure procedure and there is certain correlation between the three genes.

Objective To explore the follow-up value of phonocardiogram D/S ratio in CHF patients with treatment.Methods Forty-eight CHF patients who had never under-went regular treatment were collected in our hospital,given the regular anti-heart failure treatment for 3 months.NYHA heart failure classification,resting heart rate(RHR),and D/S ratio of phonocardiogram were recorded,six-minutes walk distance(6MWD),Left ventricular end diastolic diameter(LVEDd),the left ventricular ejection(LVEF) were tested before and after treatment.After 3-month treatment,the resting heart rate 65 times as the watershed,the patients were classified into two groups:one was up to standard,and the other was not up to standard.D/S ratio,RHR,6MWD,LVEDD,LVEF and the improvement of the heart function were compared between the two group.Results Exception the resting heart rate,the in-dicators had no significant improvement in the group of not up to standard compared with the before treatment,and D/S ratio, 6MWD,LVEF was improved significantly after three months treatment(P <0.05).In the group of up to standard,the D/S ratio was improved significantly after one months treatment(P <0.05),while after three months treatment all indicators were improved significantly(P <0.05).Comparison between the two groups,the RHR,D/S ratio were significantly improved(P <0.05 ),LVEF was significantly improved after three months treatment(P <0.05).At the same time,the D/S ratio,6MWD and NYHA classifica-tion of cardiac function was significant negatively correlated(P <0.05).Conclusion The D/S ratio could reflect heart functional im-provements in patients with CHF after anti-heart failure treatment,and it could reflect the heart functional improvement earlier and more significant in the group up to standard,it has a good clinic follow-up value in CHF patients with anti-heart failure treatment.

Objective To monitor the quality changes of iodized salt and analyze its impact factor in Chongqing between 2001 and 2009. Methods Salt samples were collected according to the east, west, south,north and center locations in iodized salt production, wholesale and household sectors. Two units in iodized salt production and wholesale segment were sampled from north, south, east and west places and only 1 unit was sampled from the central place. Nine samples were collected every month in each place. If the place had less than 9 units, and then taken all the units. About resident household, 2 townships were sampled from north, south, east and west places, and 1 township was sampled from the central place, then 20 samples were collected from each township. Iodine content was detected by oxidation-reduction assay. The index of mean iodine, qualified rate from factories and wholesale, coverage rate and taking rate of qualified iodized salt in residents were calculated.Significance was analyzed by trend test, analysis of variance and X2 test. Results The qualified rate of iodized salt from the manufacturers was 92.9%(13/14) in 2001 and the rate was 100.0% each year from 2002 to 2009. The qualified rates of iodized salt from the wholesale were 88.7%(282/318) - 99.8%(431/432). The rates of 2001 and 2002 were lower than that of other years(X2 = 4.98 - 45.69, all P< 0.05 or < 0.01). The coverage rate and taking rate of qualified iodized salt in residents were 94.2% (11 154/11 841 ) - 98.9% ( 14 061/14 217), 83.5% (9 887/11 841 ) -95.8% (13 449/14 039), respectively. The rates showed an increasing tendency (F = 9.27, 26.39, all P < 0.05).The districts(counties) with qualified iodized salt consumption rate > 90% kept increasing. The mean iodine from the manufacturers and wholesale were 29.71 - 36.25, and 31.26 - 36.13 mg/kg, respectively. The iodine level showed a descending trend(F = 35.45, 140.59, all P < 0.01 ). The mean iodine level from the inhabitants were 28.84 - 30.98 mg/kg which remained stable (F = 3.05, P > 0.05 ). The iodine level from manufacturers, wholesale to inhabitants showed an descending trend(F = 38.46 - 671.23, all P < 0.01 ). Conclusions The surveillance results of iodized salt shows an increasing tendency in quality of iodized salt, eoverage rate and taking rate of qualified iodized salt. Factors that affect the quality of iodized salt is that the enterprise does not add iodine to salt strictly by the standard.
