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 compare effects of compound Xueshuantong capsule and benazepril on inflammatory cyto-kines in type 2 diabetic patients with early diabetic nephropathy (DN), and its therapeutic mechanism thereof. Methods Ninety-four patients with type 2 diabetes were divided into diabetes without albuminuria group (DM,n=24) and early DN group (DN,n=70). DN group was then divided into three subgroups:group A (n=24) treated by benazepril alone, group B (n=22) treated by compound Xueshuantong capsule and group C (n=24) treated by compound Xueshuantong capsule combined with benazepril for 3 months. Levels of fasting blood glucose, glycosylated hemoglobin, serum creatinine, blood urea nitro-gen, lipid profiles, fibrinogen and urinary albumin excretion rate (UAER) were examined before and after treatment. The se-rum levels of hypersensitive c-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-α(TNF-α) were determined as well. Results The serum levels of hs-CRP, IL-6 and TNF-αwere significantly higher in DN group than those of DM group (P<0.01). After treatment, the serum levels of UAER, hs-CRP, IL-6 and TNF-αwere significantly re-duced in groups A, B and C compared with those before treatment (P<0.01), and which were decreased more significantly in group C. The levels of blood lipids and fibrinogen decreased obviously in group C compared with those of group A and B ( P<0.01). Conclusion Compound Xueshuantong capsule combined with benazepril not only can improve the blood fat and high coagulation state in patients, but also impossibly retard the development of early DN through decreasing serum concen-trations of hs-CRP, IL-6 and TNF-αand inhibiting inflammatory reaction.

Objective: To investigate the influence of the expression of retinoic acid receptor genes on the development of B cells in lymph nodes of young children. Method: In situ hybridization was performed on the frozen section of lymph node of young children (≤age 5 ). Six digoxin labeled antisense RNA probes for retinoic acid receptors mRNA(RAR?、?、?、RXR?、?、?)were used. The expression and distribution of retinoic acid receptor genes in lymph nodes and their influence on the differentiation and maturation of B cell were observed. RT-fluorescent PCR was also used to observe the expression levels of retinoic acid receptor genes and their relation to the maturation of B cells. Results: In situ hybridization showed all the 6 retinoic acid receptor genes were expressed in lymphocytes and reticular cells of lymph node, and the distribution was widespread. RT fluorescent PCR also showed a varying expression of 6 retinoic acid receptor genes in lymph node among different age children, but lower in children younger than 1 year, and then increased gradually with the development of immune system. Conclusion: The expression and regulation of retinoic acid receptor genes may take part in the ontogenesis of B cells, and play a key role in the regulation of retinoic acid and enforce the anti-infective immunity in children.
