Objective:To compare the therapeutic effect of immediate breast reconstruction using latissimus dorsi musculocutane-ous flap after modified radical mastectomy with the conventional modified radical surgery of breast cancer. Methods:A retrospec-tive analysis of 224 female patients with Stage 0 to IIIA breast cancer was conducted. The patients were admitted to the Department of Breast Surgery of Liuzhou People's Hospital between November 2009 and July 2012. The cases were divided into two groups accord-ing to different surgical options:immediate breast reconstruction (IBR) and modified radical surgery of the breast (MRSB). After con-trastive analyses of the postoperative complications, cosmetic results, quality of life, local failure rate, distant metastases and mortality rates between the two groups, the therapeutic efficiency of the two surgeries was evaluated. Results:No statistical differences were ob-served in the postoperative complications between the two groups, such as hydrops, skin flap necrosis, limb exercise and shoulder joint motion, drainage time, and starting time of adjuvant therapy (P>0.05). The patients in the IBR group had a better quality of life than those in the MRSB group (P<0.01). The aesthetic evaluation of the breast reconstruction was favorable in 39 cases and secondary in 3 cases, which surpass the evaluation of the patients in the simple MRSB group. No obvious statistical differences were observed in the distant metastasis rate, local recurrence rate, and mortality rate between the two groups (P>0.05). Conclusion:Compared with the tradi-tional MRSB group, the option of IBR after modified radical mastectomy not only achieves similar therapeutic outcomes but also pres-ents advantages such as better aesthetic effect of the reconstructed breast, easy surgical procedures, high safety, improvement of the breast contour outline, and improved quality of life after operation. Therefore, IBR is a safe and available therapeutic method for pa-tients with early breast cancer.

Long noncoding RNAs( lncRNAs) are classified as transcripts >200 nucleotides in length with lit-tle or no evidence of protein-coding potential, and can regulate gene expression at various levels, including transcriptional regulation, posttranscriptional processing and so on.It has been widely involved in cell differentiation, individual develop-ment and other important life processes.Recent studies show lncRNA-related dysfunction plays critical roles in various dis-eases, indicating that lncRNA may serve as a new target for disease diagnosis and treatment.This review summarizes the functions of lncRNAs, including various modes of lncRNAs in regulating gene expression, the roles of lncRNAs in differen-tiation and development, and the connection between lncRNAs and malignant tumor.

BACKGROUND:How to keep the intact shape of the breast while treating tumor has been widely concerned by more doctors and patients, breast reconstruction is introduced, developed and considered an important part in the treatment of breast tumors. OBJECTIVE:To explore the feasibility and therapeutic effects of immediate breast reconstruction after modified radical mastectomy and latissimus dorsi myocutaneous flap transplantation. METHODS:We retrospectively analyzed the clinical and pathological features of 42 breast cancer patients under immediate breast reconstruction after modified radical mastectomy with latissimus dorsi musculocuraneous flap or extended latissimus dorsi musculocuraneous flap. The procedure duration, postoperative complications and cosmetic outcome were assessed. RESULTS AND CONCLUSION:Among the involved 42 patients, 33 cases underwent modified radical mastectomy, retaining the nipple and areola of breast, 9 cases underwent modified radical mastectomy, retaining the skin of breast, 24 cases underwent breast reconstruction with latissimus dorsi musculocuraneous flap, 18 cases underwent breast reconstruction with extended latissimus dorsi musculocuraneous flap. The skin flap and reconstructed breast al survived, without severe complications. According to objective evaluation results, the cosmetic outcome was good in 39 cases and fair in 3 cases. The subjective evaluation results were good in 40 cases and fair in 2 cases. Al the patients were fol owed up for 9-41 months. One patient had bone metastasis 19 months after operation and there was no case with local recurrence. Immediate breast reconstruction after modified radical mastectomy with latissimus dorsi musculocuraneous flap is a simple and feasible operation process, with optimal effects, high security, and high survival.

AIM: To compare the difference between medicinal and edible lilium brownii. METHODS: GC method was used for the determination of stigmasterol (the reference standard) in medicinal and edible Lilium brownii. And pharmacology experiment on stigmasterol was carried out. RESULTS: Stigmasterol had the antiinflammatory and anti-coughing effect. It represented the main effect of Lilium brownii. It was reasonable to be the reference standard. There were obvious differences in the stigmasterol content of medicinal and edible Lilium brownii. The stigmasterol content of medicinal Lilium brownii was much higher than that of the edible. CONCLUSION: Edible Lilium brownii can not be applied to clinical.

AIM: To study the effect of activated protein C(APC) at different concentrations on apoptosis of human umbilical vein endothelial cells(HUVECs) induced by lipopolysaccharide(LPS).METHODS: The HUVECs were induced by LPS(1.0 mg/L) as apoptotic model that was administered by different concentration of APC(10 ?g/L or 50 ?g/L).Meanwhile,the control group and induced apoptosis group induced by LPS(1.0 mg/L) stimulation were also set up.The changes of cellular ultrastructures were observed under electron microscope.The DNA ladder and TUNEL fluorescent staining were measured in cells.Annexin-Ⅴ/PI double staining was used to measure the cell apoptosis rate by flow cytometry.Cell survival rate was measured by MTT assay.The proliferating cell nuclear antigen(PCNA) expression levels in cells were also measured by Western blotting to reflect the proliferation of the cells.RESULTS: There were significant apoptotic changes in the cells induced by LPS,but the apoptotic changes were reduced and apoptosis rates were decreased in the cells treated with APC.Meanwhile,cell survival rate and the protein levels of PCNA were increased after APC treatment,particularly at the concentration of 50 ?g/L,which showed difference when compared with those induced apoptosis group by LPS(P

Objective To investigate the change of serum alkaline phosphatase (ALP) level in patients with acute cerebral infarction (ACI) and its clinical significance.Methods A total of 400 patients with ACI (ACI group) and 240 gender-and age-matched healthy controls during the same period were enrolled in this study.Serum ALP,total protein,alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and other indicators of liver function,serum creatinine (Cr),blood urea nitrogen (BUN) and other indexes of renal function were determined.ACI patients were divided into three subgroups according to the largest diameter of infarction slice on the diffusion weighted imaging (DWI):small area group (＜1.5cm),middle area group (1.5-4.0cm) and large area group (＞4.0cm).The degree of neurologic impairment at admission and the degree of nerve function recovery at discharge were assessed by National Institute of Health stroke scale (NHISS) and modified-Rankin Scale (mRS) in all patients.The relationship of serum ALP level with infarction area,NHISS score and mRS was analyzed.Results Serum ALP level was higher in ACI group than in control group [(80.1±24.4)U/L vs.(75.5±21.5)U/L,t=-2.471,P=0.014].Serum ALP level was elevated along with the increase of infarction areas in ACI group [(78.0 ± 23.3)U/L,(79.4±24.9) U/L vs.(87.7±26.0) U/L,F=4.374,P=0.013].The correlation analysis showed that serum ALP level was positively correlated with infarction area (r=0.118,P=0.019) and NHISS score (r=0.114,P=0.023),but no significant relationship was found with mRS (r=0.071,P=0.08).Multivariate regression analysis revealed that patients with high serum ALP level (＞86 U/L) had 1.691-fold higher risk for cerebral infarction than did those with low serum ALP level(＜67 U/L) (OR=1.691,95％CI:1.103～2.594) after adjusting for confounding variables including age,gender,hypertension,diabetic mellitus,heart disease (coronary heart disease and atrial fibrillation),et al.Receiver operating curves (ROC) analysis revealed that the area under the curve of serum ALP level for predicting ACI was 0.557 (95％CI:0.512～0.602,P=0.016),and its sensitivity and specificity were 43.1％ and 67.6 ％ respectively when serum ALP level was 81.5 U/L.Conclusions Serum ALP level is increased in ACI patients,which has positive correlations with cerebral infarction areas and NHISS scores.In the future,maybe,we could assess ACI by monitoring serum ALP levels or improve the prognosis of ACI patients by decreasing serum ALP levels in the future.

Objective To study the status of the self-medication behavior in children,and analyze the problems existing in medication of children by their parents,in order to provide references for the nurses to give medication guide to the parents of the children.Methods On the principle of convenience sampiing,120 hospitalized children's parents from a grade-Ⅲ A level hospitals in Jilin Province were investigated with a self-designed questionnaire.Results 79.3％ of the parents did not behaved standardly in children's self-medication,75.0％ of the parents' behaviors were not standardized in the management of the children's drugs; there was significant difference in the level of the children's self-medication among the parents with varied academic background or the age and the children's age.Conclusions The processes of self-medication in children have potential health risks,the nurses should strengthen health education,raise the parents' cognition of the risk of self-medication for children,and thus to help parents establish scientific and rational self-medication behaviors.

Objective To investigate the role of NF-κB in aldosterone-1％NaCl-induced renal injury in uninephrectimized SD rats and the potential mechanisms.Methods Thirty-teo male SD rats were uninephrectomized and treated for 4 weeks.Rats were divided into four groups randomly:control group (n=8),1％NaCl group (1％NaCl in chow,n=8),aldosterone group (1％NaCl in chow,0.75 μg/h aldosterone delayed relase by osmotic mini-pump,SC,n=8),PDTC group (1％NaCl in chow,0.75 μg/h aldosterone,SC,100 mg/kg PDTC,IG,n=8).Systolic blood pressure (SBP),urinary protein,renal function and renal morphologic were observed.The expression of intercellular cell adhesion molecule 1 (ICAM-1) and connective tissue growth factor (CTGF) were measured respectively by Western blotting and real-time PCR.The activity and location of NF-κB in renal cortex were detected by electrophoretic mobility shift assay (EMSA) and immunohistochemisty.Results Rats of aldosterone group exhibited higher blood pressure and more serious renal injury characterized by proteinuria,glomerular sclerosis compared with rats of the 1％ NaCl group.Protein and mRNA levels of ICAM-1 and CTGF were significantly increased inaldosterone group rats than those in 1％NaCl group (all P＜0.05).Moreover,all these changes were associated with an increase in NF-κB activity.Treatment with PDTC which is a specific inhibitor of NF-κB notably alleviated SBP,proteinuria and renal injury in aldosterone-infused rats.Furthermore,PDTC markedly reduced the expression of ICAM-1 and CTGF (all P＜0.05).Conclusion PDTC can alleviate aldosterone-1％NaCl-induced renal injury in uninephrectimized SD rats by preventing the expression of ICAM-1 and CTGF.

Objective To study the protective effects of activated protein C (AFC) on the apoptosis of endothelial cells induced by lipopolysaccharide (LPS) in order to clarify the mechanisms associated with the expression of some genes related to apoptosis. Method The human umbilical vein endothelial cells were incubated with LPS (1.0 μg/mL) for one hour to make the models of cell apoptosis, and then the different concentrations of AFC (10 ng/mL and 50 ng/mL) were added to the models of cell apoptosis as treatment group. Therefore, there were two groups, model group and APC treated group. The factors related with apoptosis such as P53, Bax, Bcl-2, and caspase-3 mRNA or protein level were measured by using RT-PCR and Western blotting. Results Compared with LPS stimulated cells, the expressions of P53, Bax and caspase-3 mRNA and levels of protein were decreased and the expression of Bcl-2 mRNA and protein level were increased in APC treated cells particularly in APC 50 ng/mL treated cells (P <0.05). Conclusions The APC inhibits the apoptosis of HUVECs induced by LPS via regulating the mitochondrial-dependent apoptosis pathway, and it may become a novel therapeutic agent for infection disease.
