Objective:To assess the efficacy and safety of oncoplastic breast-conserving surgery (OBCS) in the treatment of early breast cancer. Methods:The clinicopathological data of breast cancer patients who were treated with OBCS (67 cases) and standard breast-conserving surgery (SBCS;117 cases) in Affiliated Cancer Hospital of Guangxi Medical University were retrospectively analyzed. Postop-erative complication, specimen weight, margins, and surgery re-excision rate between the two groups were compared. Results:Sero-ma (14.9%versus 48.7%, P<0.001), hematoma (4.5%versus 14.5%, P=0.035), and poor wound healing (3.0%versus 11.9%, P=0.036) were more common in the SBCS group than in the OBCS group. The patient satisfaction in the OBCS group was statistically higher than in the SBCS group (P<0.05). Compared with standard surgery, oncoplastic techniques can be employed for significantly larger tumors (25.04 mm versus 21.14 mm, P<0.001). OBCS resulted in higher mean specimen weights (92.24 g versus 57.44 g, P<0.001), wider clear nearest margins (12.04 mm versus 9.58 mm, P<0.001), and wider furthest margins (24.16 mm versus 15.24 mm, P<0.001). No statisti-cal increase was observed in further surgery re-excision of margins. Conclusion:OBCS is more successful than standard wide local exci-sion in treating larger tumors and obtaining wider radial margins. Oncoplastic approach showed no increase in postoperative complica-tion rate. The postoperative complication was excellent. OBCS is a safe and effective procedure for early breast cancer.

Objective: To investigate the effects of FGFR1OP and p57/Kip2 proteins on the genesis and progression of gliomas and their clinical significance. Methods: The expression of FGFR1OP and p57/Kip2 in 54 glioma specimens was detected by SP immunohistochemical technique. The relationship between the ex-pression levels of those proteins and various clinical pathologic factors was evaluated. Results: The expres-sion of FGFR1OP and p57/Kip2 was found in 66.7% and 44.4% gliomas, respectively. The OD value of FG-FR1OP was 0.131±0.010 in high grade gliomas, and 0.118±0.010 in low grade ones, with a statistical signifi-cance (t=-5.497, P=0.000), showing that higher expression of FGFR1OP was significantly associated with glo-ma cell differentiation. The OD value of p57/Kip2 was 0.156±0.008 in high grade gliomas, and 0.165±0.006 in low grade ones, with a statistical significance (t=0.296, P=0.014), showing that lower p57/Kip2 expression was correlated with high grade gliomas. FGFR1OP was negatively correlated with p57/Kip2 in gliomas (r=-0.732, P<0.01). Conclusion: Increased expression of FGFR1OP and/or decreased expression of p57/Kip2 may play an important role in the genesis and progression of gliomas and may indicate a poor prognosis.

OBJECTIVETo explore the therapeutic effect of the temporal rotation flap combined with cartilage plasty for cryptotia correction.

METHODSFrom January 2009 to June 2012, 8 cases with cryptotia (10 ears) were treated. After complete dissection of the cartilage adhesion, the cartilage was reshaped by suture to restore its appearance. Then the temporal triangular rotation flap was transferred to cover the wound.

RESULTSNo hematoma, infection or flap necrosis happened. The follow-up period ranged from 3 months to 1 year, with an average of (6.88 +/- 2.85) months. The ear appearance kept stable with no recurrence and inconspicuous scar. Satisfactory result was achieved.

CONCLUSIONTemporal rotation flap combined with cartilage plasty is a good option for correction of mild or moderate cryptotia.

OBJECTIVETo explore the reasonable therapeutic strategy for different types of epicanthus.

METHODSPatients with epicanthus were classificated according to the shape, extent and inner canthal distance and treated with different methods appropriately. Modified asymmetric Z plasty with two curve method was used in lower eyelid type epicanthus, inner canthus type epicanthus and severe upper eyelid type epicanthus. Moderate upper epicanthus underwent '-' shape method. Mild Upper epicanthus in two conditions which underwent nasal augumentation and double eyelid formation with normal inner canthal distance need no correction surgery. The other mild epicanthus underwent '-' shape method.

RESULTSA total of 66 cases underwent the classification and the appropriate treatment. All wounds healed well. During 3 to 12 months follow-up period, all epicanthus were corrected completely with natural contour and unconspicuous scars. All patients were satisfied with the results.

CONCLUSIONSClassification of epicanthus hosed on the shape, extent and inner canthal distance and correction with appropriate methods is a reasonable therapeutic strategy.

Objective To compare radiation-induced lung injury (RILI) between concurrent and sequential combination of postoperative radiotherapy and endocrine therapy. Methods A total of 118 patients subjected by radical or modified radical operation of breast cancer were enrolled in this study and received radiotherapy and endocrine therapy between Jan 2003 and December 2007. All the patients were categorized into four groups: radiotherapy (RT) plus concurrent aromatase inhibitor(AI): RT+AI; RT plus sequential AI:RT-AI; RT plus tamoxifen (TAM): RT+TAM; RT plus sequential TAM: RT-TAM. Radiotherapy was delivered by using various energy of electron (6, 9, 12 Mev β-ray) or 6 M.V X-ray for different target with a dose of 50 Gy (2 Gy/Fx, 5 fractions per week). RILI grades were classified according to RTOG/EORTC and Aoki evaluation criteria from one month to at least one year after radiotherapy. Results 30/118(25.4 %) patients was observed with RILI, RT+AI 22.7 % vs. RT-AI 20.0 %(P =0.806), RT+TAM 35.7 % vs. RT-TAM 24.2 %(P =0.328). The incident rate of RILI was higher in elder patients(>60 yr) than in other patients (33.9 % vs.16.9 %, P =0.05). Patients with positive chemotherapy history had a higher risk of RILI than those with chemotherapy-negtive history (P =0.039). Conclusion These findings suggest that RILI are associated with age and chemotherapy history, but not correlated with the sequence of radiotherapy and endocrine therapy.

BACKGROUND: Inhibiting the degradation of extracellular matrix in the intervertebral disc can delay the degenerative process of intervertebral disc. Matrix metalloproteinases-3 (MMP3) is considered as a key enzyme for degradation of extracelular matrix components such as type II collagen and aggrecan.
OBJECTIVE:To construct the short hairpin RNA lentiviral vector targeting human MMP3 gene and to detect its efficiency of gene silence by infecting human degenerative nucleus pulposus cells.
METHODS:According to the human MMP3 mRNA (NM_002422.4) sequence, four groups of the short hairpin RNA gene sequences targeting MMP3 were designed, synthesized and annealed to form double stranded DNA fragments, which were connected with the LV3 vectors digested by BamHI andEcoRI enzymes, and then transfected into the competent cels. The positive clones were identified by PCR, and analyzed by sequencing. The packaging and titer of lentivirus were determined after transfecting 293T cells. Human degenerative nucleus pulposus cels were infected with lentivirus vector, and the transfection efficiency of each group was observed under inverted fluorescence microscope. The interfering efficiency was detected by real time-PCR and western blot at 72 and 96 hours.
RESULTS AND CONCLUSION:The ds-oligo DNA was successfully inserted into the lentiviral vector as confirmed by electrophoresis and sequence analysis. The recombinant lentivirus was harvested from 293T cels with a viral titer of 1-5 ×108 TU/mL. RNA interference targeting the GCC AGG CTT TCC CAA GCA AAT sequences with the highest interfering efficiency in MMP3 gene at 72 and 96 hours resulted in suppression of MMP3 mRNA expression by 98% and 72%, respectively; and at 96 hours, the interfering efficiency of protein expression was 57.2%. The recombinant lentivirus vector containing RNA interference targeting MMP3 gene is successfuly constructed, which lays a foundation for further studies on the MMP3 function and gene therapy.
