Objective To determine the CT and MR findings of Madelung syndrome. MethodsFive cases of Madelung syndrome were collected in our hospital from February 2006 to June 2009, including 3 cases of typeⅠMadelung syndrome and 2 cases of typeⅡ Madelung syndrome. The 5 cases were all examined by CT, meanwhile 1 case by CT enhancement scanning and 2 cases by MR. The clinical characteristics and imaging manifestations were analyzed. Results CT and MR images in 3 patients of typeⅠMadelung syndrome displayed fat accumulation within the subcutaneous tissue of the upper trunk and deep layer tissue of neck. The diffuse masses were located around the neck, upper chest and shoulders, which were called horse collarandbuffalo humps. The other 2 cases of type Ⅱ Madelung syndrome displayed fat thickening within the subcutaneous tissue of the proximal extremities, anterior chest wall, showing special appearance of vigorous sailor. All the 5 patients showed fat deposit within the subcutaneous tissue of the anterior rectus abdominis, inguina and fat accumulation within the scrotum. CT showed proliferated fat at the subcutaneous tissue of the involved regions. The CT value of proliferated fat were between -30 and -70 HU. The proliferated fat tissue all could be displayed on MR T1WI,T2WI and T2WI fat suppression sequence, with typical hypointensity on T1WI and hyperintensity on T2WI, hypointensity on fat-suppression sequence and fibrous septation presenting among fat tissue. Conclusion Combination with the history of long-term alcohol abuse, the Madelung syndrome could be diagnosed by CT and MR, which had great value in the surgical planning for identifying the extent of disease.

Objective To find out whether the benefits entitled to peasants have increased since NRCM is in place in Beijing, and to analyze the extent of such benefit increase if any. Methods The first is to calculate changes to the reimbursement ratio of hospitalization charges for the peasants covered by NRCM; the second is to calculate the role played by NRCM for alleviating the catastrophic health expenditure of peasants. Results The reimbursement ratio of hospitalization charges for peasants covered by NRCM rose from 32.4% in 2004 to 45.4% in 2007. Survey data from districts and counties in the sampling test indicate that NRCM has gained an ever growing power in alleviating the catastrophic expenditure of peasants. Conclusion Recent years have witnessed a marked growth in medical charges, peasants' income, and peasants' demand for medical services. Against such a background, NRCM can still sharply downsize their catastrophic health expenditure, and its role keeps intensifying. This proves that the fund raising speed of NRCM has greatly outpaced the growth of medical charges and peasants' demand for medical services, and NRCM is playing a more effective role in alleviating the peasants from poverty caused by diseases.

Objective:To explore the application value of ultrasonic measurement of the pubic symphysis distance in predicting pubic symphysis diastasis(PSD) during delivery.Methods:A total of 262 pregnant women from June 2021 to July 2022 who delivered at Suzhou Wuzhong People′s Hospital and Jiangyin People′s Hospital were retrospectively analyzed. The patients were divided into PSD group of 26 cases and normal pregnant women group (control group) of 234 cases according to whether or not PSD was confirmed during postpartum follow-up. Relevant data of the two groups were collected, including the biparietal diameter and femoral length of the fetus within 7 days before delivery, the pubic symphysis distance of pregnant women when the cervix was not dilated, pubic symphysis distance when the cervix dilated to 5 cm during the first stage of delivery, and the pubic symphysis distance after delivery, the age of the pregnant woman, the gestational week, the number of pregnancies, and the birth weight of the fetus. The differences of the above relevant data between the two groups were compared.Spearman correlation analysis was used to analyze the correlation between various parameters. The occurrence of postpartum PSD, and Logistic regression was used to analyze the predictive value of various parameters on the occurrence of postpartum PSD. ROC curve was used to analyze the diagnostic efficacy of each parameters to predict PSD.Results:The fetal birth weight, number of pregnancies, pubic symphysis distance in three time points in the PSD group were significantly higher than those in the control group (all P<0.05). The age of the pregnant women was negatively correlated with the occurrence of postpartum PSD ( rs=-0.152, P=0.014). The fetal birth weight, the number of pregnancies, the pubic symphysis distance in the cervix no-dilated and the first stage of labor were positively correlated with the occurrence of postpartum PSD( rs=0.160, 0.166, 0.678, 0.581, all P<0.05). Logistic regression analysis showed that the increase of pubic symphysis distance before labor would increase the risk of postpartum PSD, and the difference was statistically significant ( OR=2 506.028, 95% CI=14.293-439 402.630, P=0.003). The increase of pubic symphysis distance at the first stage of labor increased the risk of postpartum PSD, with a statistically significant difference ( OR=10 704.027, 95% CI=33.830-3 386 803.429, P=0.002). The ROC curve analysis showed that the area under the curve of the pubic symphysis distance in the cervix no-dilated and the first stage of labor for the diagnosis of PSD were 0.896 and 0.917 respectively, the sensitivity were 0.731 and 0.885, the specificity were 0.940 and 0.829, and the corresponding critical values were 0.87 cm and 1.06 cm respectively. The area under the curve of the combination of the two parameters for the diagnosis of PSD was 0.930, the sensitivity was 0.885, and the specificity was 0.876. Conclusions:Ultrasonic measurement of pubic symphysis distance during delivery can predict the occurrence of postpartum PSD in pregnant women and can provide a basis for the occurrence and treatment of postpartum pubic symphysis separation in pregnant women.
