Objective To explore a new methodology for surgical treatment of severe retracted nipple in women. Methods 20 patients with inverted nipple and 4 recurred patients were involved in this study. Firstly, the site of neonipple tip was marked in the central part of the inverted nipple and its mean diameter usually was 1.2-1.5 cm. Then two shallow and deep triangular pedicled flaps were designed, respectively, in both superior and inferior areas near areola. With temporary traction of the nipple apex provided by a stay suture, the fibrotie bands underneath the nipple base might be cautious-ly released. Moreover, the shallow skin flaps should be about 0.5 cm in thickness and their blood sup-ply was from the subdermal arterial rete of the areola, which were used to cover and reconstruct the neck area of neonipple after a clockwise rotation and advancement simultaneously. While the deep fas-cia tissue flaps were revolved and advanced either horizontally to the opposite pedicle or upward to the inner tip through the tunnel underneath the nipple base in order to improve the height or width of the neonipple neck and prevent flattening as the supporting tissue and their blood supply was from some small perforating branch arteries in the deep part of mammary gland. Finally, purse-string suture was necessary in the base of neonipple which played a key role in avoiding recurrence of nipple inversion. Four vertical diamond-shaped excision-suturation treatment in neck area could make improvemts on the height of those stout and short nipples. Results In all 24 cases corrected by shallow and deep triangu-lar flaps rotation, after 3-6 months' follow-up, there were no complications related to surgery such as infection, hematoma, permanent sensory disturbance, or nipple necrosis, and postoperative recovery was rapid and uneventful. Especially, follow-up data revealed no evidence of recurrence of inversion and all patients were satisfied with their results. Conclusions Triangular flaps and fascia-tissue flaps in shallow and deep areola rotation is effective and easy to be popularized in correction of inverted nip-ple. This technique can improve both the diameter and height of the nipple, and certainly lower the re-currence rate of nipple inversion and achieve good aesthetic results.

Objective To explore the effect of the position of the biliary stents on the short?term and long?term effects of the patients with low malignant obstructive jaundice after treatment.Methods Seventy?eight patients with low?grade malignant obstructive jaundice diagnosed in Jiangyin Hospital Affiliated to Medical College of Southeast University who underwent biliary stenting were enrolled as the study object.According to the placement of the biliary stents,the stents were divided into the spanning group and the non?crossing group.The baseline data and related serological indexes were recorded,and the changes of jaundice between the two groups were compared by repeated measurements.All patients were followed up for 48 weeks.Multivariate Cox regression analysis was applied on the risk factors that might affect the prognosis of patients, and the degree of influence of various factors on the prognosis of patients was further evaluated.Results Repeated measures analysis showed that the biochemical indicators of the spanning group and the non?crossing group showed a significant downward trend and the difference was statistically significant (TBil: Fintra?group＝9.392,Pintra?group＝0.000; DBil: Fintra?group＝7.581,Pintra?group＝0.001).Among them,the total bilirubin (TBil) (Preoperative: (318.69±101.13) μmol／L,1 week after surgery: (135.98 ±63.61) μmol／L,2 weeks after surgery: (60.21±24.81) μmol／L) was lower than the non?crossing group preoperative: (309.07±109.97) μmol／L,1 week after surgery: (158.87±66.92) μmol／L,2 weeks after surgery: (75.91 ± 20.46) μmol／L), and the difference was statistically significant ( Finter?group ＝3.362, Pinter?group＝0.041).The direct bilirubin ( DBil) ( Preoperative: (171.93 ± 73.01) μmol／L,1 week after surgery: (90.38± 57.33) μmol／L,2 weeks after surgery:(36.64± 18.95) μmol／L) was lower than the non?crossing group ( Preoperative: ( 174.53 ± 82.74) μmol／L,1 week after surgery: ( 107.85 ± 49.07) μmol／L,2 weeks after surgery: ( 37.87 ± 14.55 ) μmol／L.The difference was statistically significant (Finter?group＝6.284,Pinter?group＝0.003).There was an interaction between the treatment regimen and treatment time (1 week after surgery and 2 weeks after surgery) (TBil: Finteraction＝12.262,Pinteraction＝0.000; DBil:Finteraction＝10.254,Pinteraction＝0.000).The results of the multi factor Cox proportional hazard model of the spanning group and the non?crossing group showed that the ALP, DBil, TBil and lymphatic metastasis of malignant tumor were the two independent risk factors that affect the prognosis.However, the pancreatic cancer,ALT and age in the spanning group across the ampulla also have a certain effect on the prognosis of the patients.Conclusion The effect of the placement of biliary stents across the Vater ampullary was more obvious in the short term on the decline of bilirubin.But in the long term,there was no significant difference in the prognosis of patients with biliary stenting position.ALP,TBil,DBil,and disease classification were all important risk factors affecting the prognosis of two groups of patients

Objective To discuss the role of empowerment management mode in radiation protection after 125I seed implantation.Methods A total of 66 patients,who received first-time 125I seed implantation at the authors'hospital from October 2020 to October 2022,were randomly divided into control group(n=33)and study group(n=33).The patients of the control group received traditional health education,while the patients of the study group received the empowerment management mode on the basis of the traditional health education.The self-efficacy,health education effect,and protection compliance were compared between the two groups.Results The self-efficacy,health education effect,and protective compliance of patients in the study group were better than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion The implementation of health education by empowerment management mode can improve the effect of health education in patients after 125I seed implantation,and the patients can get better understanding about 125I seed therapy,which can strengthen their sense of self-efficacy and improve postoperative protection compliance,ensuring the safety of the surrounding crowd.The empowerment management mode is worthy of clinical promotion.(J Intervent Radiol,2024,32:82-85)
