Purpose: To analyze and study the characteristics of diagnosis, multidisciplinary treatment including surgery, chemotherapy and radiotherapy of pregnancy-associated breast cancer. Methods: 9 cases of pregnancy-associated breast cancer were diagnosed and treated in the Department of radiotherapy of Henri Mondor Hospital, the Xllth University of Paris, from December 1992 to June 1999. 3 cases were diagnosed during pregnancy, while the other 6 were diagnosed within one year following pregnancy. 5 cases were treated with breast conservative therapy, 4 cases with modified radical mastectomy. Post-operative radiotherapy was delivered to all of the 9 cases, and 7 cases accepted chemotherapy. Results: 7 of the 9 mammographies and all the 5 breast ultrasonographies revealed tumor images. The stage at the diagnosis was generally late, the proportion of stage I , II and fT was 11 % , 44% and 44% respectively. The median follow-up time was 60 months (9-89 months), disease-free survival was observed in 6 cases, 3 cases had local recurrence or distant metastasis at 14 months to 48 months after the completion of treatment. Conclusions: Delay of diagnosis is frequently observed in pregnancy-associated breast cancer, especially in these cases diagnosed after delivery. Attention should be paid to the physical examination and ultrasonography of the breast during pregnancy and lactation. The principal of treatment is to take into account both the urgency of the disease and the safety of the fetus. Under the condition that the chemotherapy and radiotherapy could be delivered without delay, breast conservative treatment is feasible in early stage pregnancy associated breast cancer

Objective To treat hydrosalpinx by using interventional embolization of fallopian tube or laparoscopic salpingectomy before the performance of auxiliary reproductive technology,i.e.in vitro fertilization and embryo transplant (IVF-ET),and to compare the clinical effect,technical advantages and disadvamages between the two methods.Methods A total of 170 patients with tubal infertility who had received IVF-ET were selected,the clinical data were retrospectively analyzed.The patients were divided into three groups:(1) interventional embolization group (n=65),using interventional embolization for hydrosalpinx;(2) laparoscopic salpingectomy group (n=55),adopting laparoscopic salpingectomy for hydrosalpinx;and (3) control group (n=50):for these patients bilateral proximal fallopian tube obstruction was performed,and IVF-ET was directly carried out if the patient had no hydrosalpinx.Results No statistically significant differences in the used dosage of gonadotropin (Gn),E2 level on HCG-injection day,the number of follicles on HCG-injection day,the number of retrieved oocytes,the fertilization rate,cleavage rate,clinical pregnancy rate,abortion rate,and ectopic pregnancy rate existed between each other among the three groups (P＞0.05).The technical success rate in both interventional embolization group and laparoscopic salpingectomy group was 100％.No severe complications occurred.The interventional embolization procedure had some advantages,it could be completed at clinic room,the operation time was short,no anesthesia was needed,the medical cost was low,etc.Conclusion Interventional embolization of fallopian tube and laparoscopic resection are equally effective in treating hydrosalpinx before IVF-ET is conducted.Both methods can improve pregnancy outcome,but interventional embolization method is more simple,safe,economical and effective,which deserves to be the preferred method of treatment.

Objective: To investigate the activities of daily living and the use of assistive devices among disabled people demanding assistive devices in Jiading Township, Jiading District, Shanghai Municipality, so as to provide the evidence for the implementation of rehabilitation interventions and the selection of assistive devices for the disabled people living in the community. Methods: The disabled people demanding assistive devices were sampled from 17 communities in Jiading Township in January 2020. A face-to-face questionnaire survey was conducted to collect participants'age, gender, type of disability, provision and use of assistive devices. The activities of daily living were evaluated using the Activities of Daily Living Scale, and the difference in the frequency of assistive device use was compared among the disabled people with different activities of daily living. Results: A total of 377 questionnaires were allocated, and 328 valid questionnaires were recovered, with an effective recovery rate of 87.00%. The respondents included 187 men ( 57.01% ) and 141 women (42.99%), and had a mean age of ( 71.78±13.86 ) years. Among all respondents, limb disability was predominant (248 people, 75.61%), and 84.45% (277 people) were provided with assistive devices. Assessment of activities of daily living showed complete self-care in 85 respondents ( 25.91% ), functional decline in 39 respondents ( 11.89% ) and functional dysfunction in 204 respondents ( 62.20% ). The proportion of functional dysfunction was predominantly detected among disabled people at ages of 80 years and older ( 79.63% ) ( P<0.05 ). Of the disabled people with assistive devices, 139 people used the devices daily ( 50.18% ), and the proportion of daily use of assistive devices was significantly higher in people with functional dysfunctions than in those with complete self-care ( 59.33% vs. 29.41%; P<0.05 ). In addition, no need was identified as the predominant cause of non-provision of assistive devices ( 29 people, 56.86% ). Conclusions Functional dysfunction of daily living is highly prevalent among the disabled people demanding assistive devices in Jiading Township, in whom the elderly are predominant, and the proportion of assistive device use is high among people with functional dysfunctions. The provision of assistive devices recommends to be improved based on assessment of activities of daily living.

Objective:To investigate the feasibility of using anastomotic stoma as a long-term vascular access to maintain hemodialysis in patients who cannot establish an effective vascular access after ACUSEAL graft occlusion.Methods:A rare case of brachial artery-right atrium ACUSEAL artificial blood vessel fistula bypass to establish vascular access occlusion, the use of artificial blood vessel anastomosis stoma to establish buttonhole puncture as a long-term vascular access and the corresponding nursing methods.Results:At present, the patients were treated with regular dialysis for 32 months and blunt needle puncture for 23 months.Conclusions:Brachial artery-right atrium ACUSEAL graft is a rare vascular access surgery. As a new type of access with depleted autologous vascular resources, the efficacy is not certain. Because it is different from the traditional vascular prosthesis surgery, once the thrombotic occlusion of the graft fails, the risk and difficulty of reopening by interventional or surgical methods are great. Therefore, it is a challenging and reasonable method to use the limited residual cavity of the anastomosis as a long-term vascular access after occlusion to prolong the service life of the graft.

AIM:To establish a mouse model of immuno-inflammation in central nervous system (CNS) associated with cognitive dysfunction.METHODS:C57BL/6J male mice were divided into 3 groups.Lipopolysaccharide (LPS) was intraperitoneally injected into the mice to induce cognitive impairment.Morris water maze test, passive avoidance test and pole test were used to observe the behavioral changes of mice.The histomorphology was analyzed by the method of immunofluorescence.The detailed molecular mechanism was determined by Western blot.RESULTS:Compared with saline group, LPS induced mouse sickness behavior and memory loss.Microglia activation and neuronal loss in the hippocampus were observed.The expression of neuroinflammatory proteins COX-2 and iNOS in the brain of LPS-induced mice was increased.CONCLUSION:Intraperitoneal injection of LPS induces cognitive dysfunction in mice.
