Objective To investigate the radiological features of intracranial white epidermoid cysts(WECs).Methods A retro-spective analysis was conducted on the CT and MRI findings of 7 patients pathologically confirmed with WECs.All patients under-went plain CT and MRI scans,and six patients underwent enhanced MRI scans.Results All cases were solitary lesions,located in the right middle cranial fossa(2 cases),suprasellar area(2 cases),left cerebellopontine angle(1 case),right cerebellar vermis(1 case),and cerebellomedullary cistern(1 case),respectively.The lesions appeared oval or irregular in shape with clear boundaries and no perile-sional edema.The CT scans predominantly showed high density in 7 cases,with calcification in 1 case.On T1WI,7 cases exhibited high signal with mixed signals in some areas;6 cases showed primarily low signal on T2WI and fluid attenuated inversion recovery(FLAIR),with 1 case predominantly showed high signal;all 7 cases demonstrated low signal on diffusion weighted imaging(DWI).The margins of 1 lesion appeared"curly",and another exhibited a"swirl"pattern.5 cases had no enhancement,while 1 case had mild marginal enhancement.Conclusion Intracranial WECs has certain imaging characteristics.When a cystic lesion shows high density on CT,predominantly high signal on T1WI,and mostly no enhancement,considering the possibility of WECs.

Objective To investigate the effect of modified suture on the maternal skin healing, scar healing and satisfaction to cesarean section. Methods A total of 244 cases of cesarean section in our hospital from January 2015 to January 2016 were randomly collected and divided into observation group (n=143) and control group (n=101). Patients in the observation group were treated with the modified suture method, and the control group was given the conventional method to suture the skin. The VAS score, suture time and complication rate were observed in the 2 groups. Results The VAS scores were significantly lower at one week and one month after operation (1.15±0.43 and 0.07±0.01, respectively) than those of the control group (1.40±0.51 and 0.13±0.03, respectively, P<0.05). The suture time were significantly shorter in the observation group (5.12±0.95) than those of control group (7.28±0.83, P<0.05). Postoperative complication rate was significantly lower in observation group (2.80%) than that of control group (9.90%, P<0.05). The comfort level to incision and satisfaction rate to scar were significantly higher (94.41% and 95.10%, respectively) than those of control group (83.17% and 87.13%, respectively). The average thickness of scars at day 90 and day 180 after operation were significantly less in the observation group [(2.14±0.32) mm and (3.08±1.02) mm, respectively] than those of the control group [(3.10±0.48) mm and (5.22±1.10) mm, respectively, P<0.05)]. Conclusion The improved suture method after cesarean section has the advantages of shorter suture time, less poor wound healing, higher maternal satisfaction rate.
