Objective To explore a new surgical method for the treatment of refractory fistula after breast augmentation and to improve patients healing efficiently.Methods This paper had collected two groups,a total of 178 cases of injected breast augmentation,who had shown the polyacrylamide hydrogel(PAAG)mixture shift,and caused abdominal fistula.Among them,89 cases further adopt new design in the treatment of fistula by using breast muscle membrane tissue flap and improve the effect of fistula treatment after the removal of fistula.And the other 89 cases were token the pure clean the cavity away caused by the abnormal material shift into the chest and abdominal wall.Results It was observed that PAAG widely distributed in the chest and abdominal wall and formatted the fistula connected mammary gland,axillary,chest abdominal wall.The area of lesions lacuna shrink by 80％ for the group used tissue flap after 2 weeks,but those not with tissue flap shrink by 45％(P＜0.01).At 4th week,all the patients of flap group achieved tissue healed,while the completely heal ratio of control group was only 73％.Compared two groups of healing rate,the group with tissue flap was obviously better than ones only with surgical method.Conclusion It suggests that main reasons for the liquidity bag and huge cavity are PAAG mixture shift into thoracic and abdominal wall and formed chronic fistula and connected the chest and abdominal wall.Local muscle membrane tissue flap can obviously promote the chest and abdominal wall fistula healing.

Objective:To explore the relation between parental cohesion,peer acceptance and the loneliness of left-behind children,and furthermore explore the mediation role of self-esteem.Methods:Totally 427 left-behind children in Hubei Province (275 males,152 females) were surveyed,and the Parental Cohesion Scale (PCS),Peer Nomination (PN),Self-Esteem Scale (SES) and Children Loneliness Scale (CLS) were used to assess parental cohesion,peer acceptance,self-esteem and loneliness respectively.The relation between parental cohesion,peer acceptance andthe loneliness of left-behind children,and the mediation role of self-esteem wereanalyzed.Results:The CLS scores in left-behind children were negatively correlated with the scores of PCS,PN,and SES (r =-0.31,-0.37,-0.50,P ＜ 0.01),the SES scoresplayed a mediation role in the relation between PN scores and CLS scores (95 ％ CI:-7.02--0.01),and between PCS scores and CLS scores (95 ％ CI:-0.18--0.09).Furthermore,the unique effect of the PN scores on the CLS scores (sr2 =0.10) was higher than that of PCS scores (sr2 =0.06).Conclusion:The current research indicates that the loneliness,parental cohesion,peer acceptance and self-esteem of the left behind children have a close relationship.Furthermore,it suggests that self-esteem may play partial mediating effects between parental cohesion,peer acceptance and the loneliness of left-behind children.

Objecfive To observe the changes of regional cerebral blood flow (rCBF) in systemic lupus erythematosus (SLE) patients with neuropsychiatrie disorders and evaluate rCBF SPECT imaging in the detection of neuropsychiatric problems in SLE patients.Methods Twenty neuropsychiatrie SLE patients were enrolled in the study and were performed SPECT rCBF imaging anti CT/MRI scans,respectively.Twenty SLE patients without neuropsychiatrie manifestatiuns (SLE) and 20 healthy volunteers also underwent SPECT rCBF imaging as controls.Semiquantitative analysis was conducted as designed by selecting 3 consecutive crosssections and delineating ROI,which generated HQ and the results were compared between with SLE and controls.Results SPECT rCBF findings were almormal in 20 NPSLE.in which 19 of the 20 with abnormal SPECT findings showed focal uptake defects the other patient showed increased foeal uptake.Four N PSLE patients had ahnormal CT/MRI scans findings.Compared with the methods of rCBF and CT/MRI imaging,the difference was significant (P＜0.01).Nineteen SLE patients without neuropsychiatrie manifestations had normal SPECT findings.the other 1 patient showed focal uptake defect.SPECT findings were all normal in 20 healthy volunteers.Temporal cortex was the most commonly involved region,followed by frontal cortex.Specific values generated from semiquantitative analysis (HQ) of temporal and frontal regions in neruopsychiatrie SLE patients were lower than that in SLE patients and healthy volunteers (P＜0.01 and P＜0.05).Conclusion SPECT rCBF imaging has the potential to be a sensitive tool to detect the neuropsyehiatric disordersin SLE patients,and has important value in helping for early diagnosis and therapy.Hypoperfusion on ECD-SPECT under the territory of the middle cerebral artery (MCA) is the most common observation,and which temporal and frontal regions are the most frequently involved regions in neruopsychiatrie SLE patients.

Objective To assess the echocardiographic characteristics of embolism and in-hospital mortality in patients with infective endocarditis using three-dimensional transesophageal echocardiography (3D TEE).Methods Retrospective review of 124 patients with native valve infective endocarditis was performed to examine its characteristics by two-dimensional transthoracic echocardiography (2D TTE),multi-plane and 3D TEE.The primary endpoint was embolism and mortality that occurred within one month before or after operation.The combined simple score was calculated by assigning 1 point each for the presence of large vegetation,abscess or fistula,rupture of valvular chord,moderated or severe valvular regurgitation and perforation or serious valvular destruction.Hosmer and area under the curve was calculated to predict embolism and adverse events with the combined simple score,length of vegetation,serious valvular destruction with abnormal morphology.Results In 124 patients,embolic events occured in 27 cases (27/124,21.77％).Multi-plane and 3D TEE can identify the exact location and length of vegetation compared with 2D TTE,which miss-diagnosed vegetation in left atrium and papillary muscle.The clinical presentation of embolism patients was remarkable for lower hemoglobin level (P＜0.05).The ratio of multi-located vegetation,mortality and serious valvular destruction with abnormal morphology were higher in embolism and adverse events patients than those in non-embolism and adverse events patients (all P＜0.05).The area under the curve of combined simple score,lengh of vegetation for embolisms and adverse events and serious valve destruction with abnormal morphology for embolism and adverse events were 0.65 (P=0.06),0.60 (P=0.19)) and 0.70 (P=0.03).Conclusion Multi-plan and 3D TEE plays a key role in the diagnosis of patients with infecitive endocarditis,especially vegetations in occasional location.Serious valve destruction with abnormal morphology is associated with embolism and adverse events.

AIM:To observe the effects of adipose differentiation-related protein ( adipophilin) on the expres-sion of inflammatory factors in RAW264.7 macrophage and to clarify the related mechanism.METHODS:The cell models with high expression and low expression of adipophilin were constructed by transfecting PA317 packaging cells with stable high or low expression adipophilin retroviral vectors into the RAW264.7 cells.The concentrations of IL-6, MCP-1 and TNF-αin the cell culture medium were detected by ELISA.The protein levels of AP-1, p-AP-1, ERK1/2 and p-ERK1/2 were measured by Western blot.The protein levels of adipophilin, p-ERK1/2 and p-AP-1 and the releases of the inflamma-tory factors in the RAW264.7 cells treated with or without ERK1/2 inhibitor PD98059 or AP-1 inhibitor curcumin were de-termined.RESULTS:The RAW264.7 cells with high expression of adipophilin had higher levels of IL-6, MCP-1 and TNF-α, and higher protein levels of p-AP-1 and p-ERK1/2 than those in the cells with low expression of adipophilin. ERK1/2 inhibitor had no significant effect on the expression of adipophilin, but the protein expression of ERK1/2 and AP-1 was significantly inhibited (P<0.05).The administration of AP-1 inhibitor curcumin had no significant effect on the protein expression of adipophilin and ERK1/2, but the protein expression of AP-1 was significantly inhibited (P<0.05). At the same time, the releases of inflammatory factors IL-6, MCP-1 and TNF-αwere significantly decreased.CONCLU-SION:Adipophilin may regulate the expression of inflammatory factors through ERK1/2-AP-1 pathway in RAW264.7 mac-rophages.

AIM:Mitochondrial DNA (mtDNA) copy number variation (CNV), which reflects the oxidant-induced cell damage, has been observed in a wide range of human diseases .However, whether it correlates with heart failure , which is closely related to oxidative stress, has never been elucidated before .We aimed to systematically investigate the association between leukocyte mtDNA CNV and heart failure risk and prognosis .METHODS: A total of 1 700 hospitalized patients with heart failure and 1 700 age-and gender-matched community population were consecutively enrolled in this observational study , as well as 1 638 ( 96.4%) patients were fol-lowed prospectively for a median of 17 months (12~24 months).The relative mtDNA copy number in leukocyte of peripheral blood or cardiac tissue was measured in triplicate by quantitative real-time PCR method .RESULTS:Patients with heart failure possessed much lower relative mtDNA copy number compared with control subjects (P<0.01), especially for the patients with ischemic etiology (P<0.01).Patients with lower mtDNA copy number exhibited 1.7 times higher risk of heart failure ( P<0.01).Long-term follow-up (median 17 months) showed that decreased mtDNA copy number was significant associated with both increased cardiovascular deaths (P<0.01) and cardiovascular rehospitalization (P<0.01).After adjusted for the conventional risk factors and medications , lower mtDNA copy number were still significantly associated with 50% higher cardiovascular mortality (P <0.05).CONCLUSION:
mtDNA copy number depletion is an independent risk factor for heart failure and predicted higher risk of cardiovascular deaths in patients with heart failure .

Objective. DNA modification fixed as mutations in the cells may be an essential factor in the initiation step of chemical carcinogenesis. In order to explore the mechanism of gene mutation and cell transformation induced by glycidyl methacrylate (GMA), the current test studied the characteristics of GMA-DNA adducts formation in vitro.Methods. In vitro test, dAMP, dCMP, dGMP, dTMP and calf thymus DNA were allowed to react with GMA (Glycidyl Methacrylate). After the reaction, the mixtures were detected by UV and subjected to reversed-phase HPLC on ultrasphere ODS reversed-phase column, the reaction products were eluted with a linear gradients of methanol (solvent A) and 10mmol/L ammonium formate, pH5.0 (solvent B). The synthesized adducts were then characterized by UV spectroscopy in acid (pH1.0), neutral (pH7.2), alkaline (pH11.0) and by mass spectroscopy.Results. The results showed that GMA could bind with dAMP, dCMP, dGMP and calf thymus DNA by covalent bond, and the binding sites were specific (N6 of adenine, N3 of cytosine). Meanwhile, a main GMA-DNA adduct in the reaction of GMA with calf thymus DNA was confirmed as N3-methacrylate-2-hydroxypropy1-dCMP.Conclusions. GMA can react with DNA and /or deoxynucleotide monophosphate and generate some adducts such as N6-methacrylate-2-hydroxypropyl-dAMP and N3-methacrylate-2-hydroxypropyl-dCMP, ets. Formation of GMA-DNA adducts is an important molecular event in gene mutation and cell transformation induced by GMA.
