Objective To explore the clinical significance of preserving the intercostobrachial nerve (ICBN) in the radical resection of breast cancer. Method All of 140 cases of breast cancer with Ⅰ - Ⅲ a stage operable eligible,were randomly divided into the experimental group with 79 cases (7 cases were rejected, 1 case was lost) that patients received radical resection of breast cancer with preservation of ICBN,and the control group with 61 cases (2 cases were lost) that patients received routine radical resection of breast cancer based on the time of admission. Analyzed postoperative local recurrence and compared to sensory dysfunction of the two groups. Results There was no significant difference between the two groups of patients in the rate of postoperative local recurrence [0-4.2% ( 3/71 ) vs. 0-3.4% (2/59)] ( P > 0.05 ). The local sensory disturbance of the experimental group [2.8% (2/71 )-11.3% (8/71)] was significantly lower than the control group [54.2%(32/59)-71.2%(42/59)], there was significant difference between the two groups (P < 0.01 ). Conclusion Radical resection of breast cancer with preservation of ICBN is an ideal operation in breast cancer.

OBJECTIVETo investigate the influence of the DNA integrity of optimized sperm on the embryonic development and clinical outcomes of in vitro fertilization and embryo transfer (IVF-ET).
METHODSThis study included 605 cycles of conventional IVF-ET for pure oviductal infertility performed from January 1, 2013 to December 31, 2014. On the day of retrieval, we examined the DNA integrity of the sperm using the sperm chromatin dispersion method. According to the ROC curve and Youden index, we grouped the cycles based on the sperm DNA fragmentation index (DFI) threshold value for predicting implantation failure, early miscarriage, and fertilization failure, followed by analysis of the correlation between DFI and the outcomes of IVF-ET.
RESULTSAccording to the DFI threshold values obtained, the 605 cycles fell into four groups (DFI value < 5%, 5-10%, 10-15%, and ≥ 15%). Statistically significant differences were observed among the four groups in the rates of fertilization, cleavage, high-quality embryo, implantation, clinical pregnancy, early miscarriage, and live birth (P < 0.05), but not in the rates of multiple pregnancy, premature birth, and low birth weight (P > 0.05). DFI was found to be correlated negatively with the rates of fertilization (r = -0.32, P < 0.01), cleavage (r = -0.19, P < 0.01), high-quality embryo (r = -0.40, P < 0.01), clinical pregnancy (r = -0.20, P < 0.01), and live birth (r = -0.09 P = 0.04), positively with the rate of early miscarriage (r = 0.23, P < 0.01), but not with the rates of multiple pregnancy (r = -0.01, P = 0.83), premature birth (r = 0.04, P = 0.54), and low birth weight (r = 0.03, P = 0.62).
CONCLUSIONThe DNA integrity of optimized sperm influences fertilization, embryonic development, early miscarriage, and live birth of IVF-ET, but its correlation with premature birth and low birth weight has to be further studied.

BACKGROUND: Total flavone of ginkgo biloba(TFG) can affect on free radical, but the effect on apoptosis induced by cerebral ischemia is unclear.OBJECTIVE: To study the inhibitory effect of TFG on apoptosis induced by cerebral ischemia.DESIGN: Completely randomized controlled experimental study based on experimental animals.SETTING: Department of pharmacology in a university.MATERIALS: Totally 24 SD rats in half genders with clean grade and body mass of(250 ± 50) g, were divided into 4 groups at random: sham-operation group, model group, TFG 40 rmg/kg group and TFG 80 mg/kg group (Certificate No. 01).METHODS: This study was completed in the Department of Pharmacology,Anhui Medical University during October 2001 and January 2002. Incomplete cerebral ischemia was made by ligating bilateral common carotid arteries(CCA) in rats. The cerebral injury was evaluated by brain edema. The apoptosis was determined by terminal deoxy-nucleotidyl transforase-mediated dUTP-digoxigenin nick end-labeling(TUNEL) and transmission electron microscopy (TEM) method. The DNA fragmentation analysis was measured with the diphenylamine reagent method.MAIN OUTCOME MEASURES: Major factor: Effect of TFG on ultrastructral alteration of apoptotic cerebral cortex cells; Secondary factor: Effect of TFG on DNA fragmentation induced by cerebral ischemia.RESULTS: Ligating of bilateral CCA markedly induced apoptotic cell in cerebral cortex. TFG 80 mg/kg significantly inhibited brain edema( P < 0.05 )and decreased the numbers of apoptotic cells in cortex( P < 0.01 ) and improved ultrastructral alteration of apoptotic cells; TFG 40, 80 rmg/kg also inhibited the increase of DNA fragmentation induced by cerebral ischemia (P <0.05, P <0.01).CONCLUSION: TFG has inhibitory effect on ischemia-induced apoptosis of cerebral cortex and improve the ultrastructual changes of apoptosis. Moreover,TFG can relieve the occurrence of edema of ischemic brain tissue and inhibit the increase of DNA section induced by cerebral ischemia.

OBJECTIVETo investigate the values of the sperm deformity index (SDI), acrosome abnormity rate (AAR), and DNA fragmentation index (DFI) of optimized sperm in the prediction of fertilization failure (fertilization rate < 25%) in conventional in vitro fertilization (IVF).
METHODSWe selected 695 cycles of conventional IVF for pure oviductal infertility in this study, including 603 cycles of normal fertilization and 92 cycles of fertilization failure. On the day of oocyte retrieval, we examined sperm morphology, acrosome morphology, and DNA fragmentation using the Diff-Quik, PSA-FITC and SCD methods. We established the joint predictor (JP) by logistic equation and analyzed the values of different parameters in predicting fertilization failure with the receiver operating characteristic (ROC) curve.
RESULTSThe fertilization rate was negatively correlated with SDI (r = - 0.07; P = 0.03), AAR (r = -0.49; P < 0.01), and DFI (r = -0. 21; P < 0.01). The SDI, AAR, and DFI in the normal fertilization group were 1.24 ± 0.20, (7.75 ± 2.28)%, and (7.87 ± 3.15)%, and those in the fertilization failure group were 1.42 ± 0.15, (12.02 ± 3.06)%, and (13.32 ± 4.13)%, respectively, all with statistically significant differences between the two groups (P < 0.05). SDI, AAR, and DFI were all risk factors of fertilization failure ( OR = 2.68, 14.11, and 3.85; P = 0.01, < 0.01, and < 0.01). The areas under the ROC curves for SDI, AAR, DFI, and JP were 0.651 ± 0.033, 0.895 ± 0.019, 0.789 ± 0.022, and 0.915 ± 0.017, respectively. According to the Youden index, the optimal cut-off values of SDI, AAR, and DFI obtained for the prediction of fertilization failure were approximately 1.45, 10%, and 12%.
CONCLUSIONThe SDI, AAR and DFI of optimized sperm are closely associated with the fertilization rate, and all have the value for predicting fertilization failure in IVF. The AAR is more valuable than the other single predictors, but JP is more effective than the AAR.
