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.

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.

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.

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.
