[Purpose]To analyze the survival rate of breast cancer in Qidong City of Jiangsu Province from 1972 to 2019 and to predict the trend in the next 10 years.[Methods]The data of breast cancer collected from Qidong Cancer Registry from 1972 to 2019 were extracted.Observed survival rate(OSR),relative survival rate(RSR),age-adjusted relative survival(ARS)and average annual percentage change(AAPC)of breast cancer were calculated.ARIMA model was used to predict the trend of breast cancer survival rate.[Results]The 5-year RSR increased from 57.30％during 1972-1977 to 89.01％during 2014-2019,and the uptrend of RSR in the 8 periods was statistically significant(P＜0.001).The 5-year ARS increased from 48.12％during 1972-1977 to 85.64％during 2014-2019 with an AAPC of 1.85％(t=10.113,P＜0.001).The 5-year RSR during 1972-2019 for males was 85.22％,and for females was 74.51％.For females,the 5-year RSR in-creased from 56.44％during 1972-1977 to 88.93％during 2014-2019 with an AAPC of 1.29％(t=13.087,P＜0.001),and the 5-year ARS increased from 46.14％during 1972-1977 to 85.23％during 2014-2019 with an AAPC of 1.90％(t=10.369,P＜0.001).The 5-year RSR in the age groups of 25～34,35～44,45～54,55～64,65～74,and over 75 years old were 66.91％,74.69％,76.97％,75.52％,73.44％and 66.40％,respectively;the corresponding AAPCs of 5-RSR in above age groups were 1.02％(t=3.816,P=0.009),1.03％(t=4.936,P=0.003),1.23％(t=5.826,P=0.001),1.86％(t=5.997,P=0.001),2.13％(t=10.245,P＜0.001),and 1.44％(t=6.405,P=0.001),respectively.ARIMA modeling of survival trend prediction showed that 5-RSR and 5-ARS for breast cancer will be ascended to 98.76％and 98.33％by 2028,respectively.[Conclusion]The overall survival rate of registered breast cancer cases in Qidong City has been greatly improved and will be further improved in the future,more attention should be paid to the prevention and treatment of breast cancer.

BACKGROUND:Interleukin-1 receptor-associated kinase 4 activity-induced inflammations and infection have been extensively accepted. However, there was no report concerning its effects on flap ischemia-reperfusion injury. OBJECTIVE:To explore the significance of interleukin-1 receptor-associated kinase 4 activity in flap ischemia-reperfusion injury. METHODS:A total of 36 adult male Sprague-Dawley rats were randomized into sham-operated group (n=12), ischemia-reperfusion group (n=12) and interleukin-1 receptor-associated kinase 4 group (n=12). The models of right lower abdominal island flap ischemia-reperfusion injury were set up. Interleukin-1 receptor-associated kinase 4 group was intraperitoneal y injected with 1 mL of interleukin-1 receptor-associated kinase 4 (100μmol/L) before reperfusion. The flaps were col ected at 1, 2, 4, and 6 hours after ischemia-reperfusion injury for histopathhological observation. At 1 hour after ischemia-reperfusion, protein expression of interleukin-1 receptor-associated kinase 4 was detected in flaps. The proportion of flap survival was calculated at 7 days after surgery.RESULTS AND CONCLUSION:Histopathological observation demonstrated that compared with the ischemia-reperfusion injury group, neutrophil infiltration and edema was evidently improved, and the protein expression of interleukin-1 receptor-associated kinase 4 was gradual y reduced in the interleukin-1 receptor-associated kinase 4 group. Flap survival proportions were respectively (51.70 ±7.62)%and (86.56±12.23)%in the ischemia-reperfusion injury group and interleukin-1 receptor-associated kinase 4 group at 7 days after surgery. There were significant differences in the flap survival proportion between the two groups (P<0.01). These results showed that after flap ischemia-reperfusion injury, the inhibition of interleukin-1 receptor-associated kinase 4 activities could elevate the survival rate of transplanted flap.

Objective To investigate the method and effect of free autogenous palmaris longus tendon transplantation in the treatment of moderate and severe cicatricial ectropion.Methods The autogenous palmaris longus tendon was obtained through a small lateral proximal wrist band incision (lengths from 4 cm to 6 cm).The graft was properly sutured to the exposed tarsus and the attachments of inner and outer canthus.Local skin flap was rotated to cover the tendon and to repair the wound.Results Six man (8 eyes) with moderate and severe cicatricial ectropion were treated in our department,all case of ectropion were rectified after operation.The eyeballs were well contacted with lower eyelid and no recurrence of eetropion,epiphora and corneal exposure during 6 to 18 months' follow-up.The tension of the lower eyelid was abiding with satisfied effects.Conclusions The palmaris longus tendon is easy to obtain and there is no harm to the donor site.The cicatricial ectropion could be repaired with self-palmaris longus tendon transplantation with lasting effect and the recurrence rate is lower,which is well worthy popularizing.

Objective To illustrate the details and effects of a new technique of penile augmentation-a dual plane approach to enhance the penile girth with human acellular dermal matrix (ADM)through the incision on the dorsal penile root.Methods Firstly,a reversed V incision was made at the dorsal root of the penis and the superficial suspensory ligament of the penis was released.A Dartos fascia incision was then made and the plan between Dartos fascia and Buck's fascia was dorsally dissected toward the coronary sulcus.A Buck's fascia incision was made 1.5-2 cm from the coronary sulcus and the fascia was undermined distally.One or two sheets of ADM was dorsally placed by a dual plane method which combined partial sub-Buck's fascia plane and partial sub-Dartos fascia plane to enhance the penile circumference.Finally,the Dartos fascia incision was closed and followed by the closure of the wound with V-Y advancement.Results A total of 35 patients underwent dual plane penile augmentation No dorsal penile skin necrosis and exposure of ADM sheet happened in our group postoperatively.25 patients were followed from 6 to 24 months after operation.All patients were satisfied with their penile appearance and 21 married patients reported satisfied sexual activity.The increase of penile circumference was (2.65±0.41) cm at flaccid state and (1.85±0.35) cm at erectile state 6 months postoperatively.No pleat or absorb of the ADM sheet,losses of sensitivity of the penis occurred during the follow-up period.Conclusions By adjusting the plane of ADM placement,the dual plane penile augmentation ensures adequate soft-tissue coverage and sufficient blood supply of penile skin and offers increased benefits and fewer tradeoffs compared with a single plane.This technique could be an effective way to lengthen and enlarge the penis in one stage without major complication.
