1.Research progress of surgical treatment of multifocal and multicentric breast cancer
Cancer Research and Clinic 2014;26(10):710-713
Multifocality and multicentric breast cancer (MMBC) has been attached remarkable importance.The diagnosis of MMBC is of great importance for breast cancer individualized management,particularly regarding the choice of surgical method.A discovery of MMBC may be verified decisions to perform a wider excision which will avoid the appearance of positive margins.As for the results of conservative surgery developed by MMBC,however,contradictory conclusions exist in the related documents.No general common has been reached.MMBC may also alter the solution of the axillary basin.

Objective To analysis newborn stage and long-term physiological and neuropsychological development in children born after assisted reproductive technology(ART),and to evaluate the safety of ART.Methods Eighty-four 6-month-old to 6-year-old children born after ART performed from January 1st,2006 to June 30th,2011 in Reproduction Center of Fuzhou General Hospital were taken as ART group; and 84 matched children born after spontaneous conception were as control group.The physiological and neuropsychological states of these children in their newborn stage and 6-month-old to 6-year-old duration were compared with Chi-square or t test.Results There was no statistical difference in childbearing age of mothers,the prevalence of gestational diabetes mellitus and hypcrtensive disorder complicating pregnancy,delivery mode,living environment,parents' education level,newborn birth length,birth weight,the rate of premature birth,low birth weight,asphyxia and hospitalized to neonatal intensive care unit between two groups (P>0.05).In ART group,the incidence of growth retardation and abnormal social life skills was 6.0 % (5/84) and 1.2 % (1/84),and no statistical difference were found comparing with control guoup [4.8%(4/84) and 1.2%(1/84),x2 =0.12 and 0.00,P>0.05],neither the developmental quotient (95.9±6.1 vs 94.8±5.1,t=1.25,P=0.21).Twins had higher rates of preterm birth [41.8% (33/79) vs 10.1%(9/89),x2 =22.37,OR=6.38,95%CI:2.81-14.50,P=0.00],low birth weight [51.9%(41/79) vs 6.7%(6/89),x2=42.35,OR=14.93,95% CI:5.84-38.16,P=0.00],asphyxia [10.1 % (8/79) vs 1.1 %(1/89),x2 =6.69,OR=9.92,95% CI:1.21~81.15,P=0.01],hospitalized to neonatal intensive care unit [36.7 % (29/79) vs 14.6 % (13/89),x2 =10.90,OR =3.39,95%CI:1.61-7.14,P=0.00] and growth retardation [11.4%(9/79) vs 0.0%(0/89),x2=10.71,RR=0.11,P=0.00] than singleton.Conclusions ART has no negative effects on children's physical and neuropsychological development.It could increase the incidence of twins,so that it might increase the incidences of preterm labor and low birth weight,which might affect the long-term physical and neuropsychological development of the offspring.

Objective To observe the effect of electromyographic biofeedback combined with swallowing training on dysphagia after stroke.Methods Ninety-five patients with difficulty in swallowing after stroke were randomly divided into a treatment group (48 eases) and a control group (47 cases).The patients in the treatment group were provided electromyographic biofeedback and swallowing training; the patients in the control group received swallowing training only.The therapeutic effect was assessed with Kubota's drinking water test before treatment and 30d after treatment.Results Swallowing in both groups improved after treatment.The total recovery rate in the treatment group was 87.5%,and in the control group it was 68.0%,a significant difference.Conclusion Electromyographic biofeedback can improve the effectiveness of swallowing training after stroke.

AIM To evaluate the anti-angiogenesis action of Bevacizumab on corneal neovascularization(CNV) in rats induced by alkali burns.·METHODS: 20 Health Wistar rats, aging from 6 to 8 weeks and weighting from 170g to 190g from 170g to 190g were prepared for CNV animal models. Both corneas of each animal in experimental were cauterized with alkali, then all rats were randomly divided into four groups (each group have 5 rats and 10 corneas), the both corneas of each rats were received subconjunctival Bevacizumab in different dosage (group 2, 0.5rag; group 3, 1.0mg; group 4, 2.0mg)and the group 1 received carrier solution. The occurrence and development ofCNVwereobservedbyslit-lamp microscope, and length and area of CNV were calculated. All rats were followeded up 16 days after alkali burns. The 40 corneas were taken for histopathological examination. Vascular endothelial growth factor (VEGF) were detected in all rat corneas by immunohistochemistry method. ·RESULTS: In the bevacizumabotreated eyes, the vascular area was lower than in the control eyes. The treated group was statistical differences compared with the control group; when vascular area were compared between the treated groups, no statistical differences were observed. The histopathological findings showed that the inflammation cells and the neovascularity in each treated group were significantly fewer than that in the control group. The expression of VEGF markedly increased in CNV control group compared with bevacizumab-injected group. ·CONCLUSION: Subconjunctival application of a certain concentrations Bevacizumab could inhibit angiogenesis in rats corneas induced by alkali burns.

Background Vitretomy and lenstomy with silicone oil tamponade is an effective method for complicated vitreous retinopathy.The severe anisometropia after silicone retention is usually treated by two-point transscleral suture fixation for posterior chamber intraocular lens(IOL)implantation.In order to reduce the number and difficulty and complication of the operation,the surgical method should be improved.Objective The goal of this study was to observe the resuh of silicone oil removal combined with four-point trans-scleral suture fixation of posterior chamber IOL after vitrectomy.Methods A retrospective case-observational study design was adopted.Twenty eyes with silicone oil tamponade from 20 patients without lens and posterior capsule after vitrectomy were included in this study.Silicone oil removal with four-point trans-scleral suture fixation of posterior chamber IOL was performed.The anterior ocular inflammatory response,intraocular pressure,uncorrected and corrected acuities before and after operation,corneal endothelial cell counting and postoperative complications were observed and analyzed.Written informed consent was obtained from all patients prior to the operation.Results All of the operative eyes in this study showed improvement of visual acuity after operation.Of the 20 eyes,a visual acuity of ≥0.8 was seen in 2 eyes,0.6-0.7 in 6 eyes,0.3-0.5 in 8 eyes and 0.05-0.2 in 4 eyes 3 months after the removal of silicone oil.The uncorrected acuity postoperation was significantly improved in comparison with preoperation(H=10.147,P<0.01),but no significant difference was found in the corrected acuity between preoperation and postoperation(X =2.089,P< 0.01).The number of the corneal endothelial cells was(2064±329)cells/mm2 before operation,and that after operation was(1987±269)cells/mm2,showing an insignificant change between them(t =1.660,P > 0.05).No abnormality of IOL position was found in all 20 operated eyes.There was not serious postoperative complication in all 20 patients.Conclusions The combination of silicon oil extraction with four-point transscleral suture fixation IOL is effective in eyes without posterior capsule or lens after vitrectomy.It can reduce the operation time and improve the postoperative acuity and the quality of life of patients.
