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.

As a pattern of manifestation of cerebral small vessel disease,cerebral microinfarct(CMI) is a very common neuropathological change in old people. It is significantly correlated w ith cognitive decline and dementia. This article review s the meuropathology, neuroimaging and clinical significance of CMI.

Objective To study on antibacterial effect of active ingredient of se-enriched Macleya cordata.Methods Penicillin sodium and saline as control, detected the average inhibition zone diameter of se-enriched Macleya cordata group ( containing 0.96 mg/mL sanguinarine) on 9 common bacteria with disc agar diffusion method;20% methanol and saline as control, se-enriched Macleya cordata group which the average inhibition zone diameter was minimum, without se-enriched Macleya cordata group and penicillin sodium were diluted with 20% methanol, made concentration of 0.48, 0.24,0.12,0.06, 0.03 mg/mL.minimal inhibitory concentration ( MIC) of each treatment group was determined by agar dilution method, evaluated antibacterial effect of se-enriched Macleaya cordata group.Results se-enriched Macleya cordata group could improve antibacterial effect significantly, the average inhibition zone of 100 μg/mL sodium selenite treatment group was minimum(Φ15.33 mm);MIC of se-enriched Macleya cordata group on E.coli O1 , E.coli P22 , E.Dublin reduced from 0.96 to 0.24 mg/mL;MIC of S.typhimurium and S.suipare were 0.12 mg/mL;MIC of S.aureus and S.suis were 0.06 mg/mL; MIC of E.Dublin and L.murrayi were less than 0.03 mg/mL.Conclusion Se-enriched Macleya cordata improves the antibacterial effect signififcantly, and it lays the theoretical foundation for development and utilization of se-enriched Macleya cordata for future.

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.

To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

A method for the determination of B6-pyridoxamine (PAM), pyridoxal (PAL) and pyridoxine (POL) by RPLC was proposed. The procedure included the addition of 0.1M H2SO4 to the sample, hydrolysis for 30 min at 120℃, centrifuging, filtration and direct analysis by ODS Cl8 column. PAM, PAL and POL were completely separated, when the flow rate of the mobile phase (pH2.0-2.1) was 1.0-1.5ml/min. Quantitation by a fluorescent detector was performed with Exc: 293 nm and Em: 395 nm. The recovery ranged from 99 to 103% with CV 5.0-5.3%. The method was simple, rapid, sensitive and reproducible.

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.
