Breast cancer is the most common malignant tumor in women. For early stage breast cancer patients, surgical treatment is still the foundation of local treatment. With background from precision medicine, this article reviews recent hot issues in surgical treat-ment for early stage breast cancer patients. We summarized strategies in surgical treatment, selection of resection range, manage-ment of local lymph nodes, timing of breast reconstruction, and the application of minimally invasive surgery.

Breast cancer is the most common malignant tumor in women. Surgical treatment is one of the important treatment methods. Breast reconstruction following mastectomy can improve patients' quality of life with acceptable oncological safety. Autologous tissue breast reconstruction has become an important way owing to its spe-cific advantages. The ideal tissue for autologous breast reconstruction is free abdominal flap. This review presented the clinical application, timing of operation and complications of breast reconstruction with free abdominal flap.

Objective: To establish the quality standards of Reduning Injection (RI) based on UV fingerprint, and improve the quality standards of RI. Methods: Full wavelength UV-vis spectrophotometer was used to scan the 15 batches of RI, a reference fingerprint was established, correlation coefficient method was used to calculate RI sample fingerprint and control fingerprint similarity, and the 14 batches of samples were verified. Results: The five batches of RI were within the validity period, their UV fingerprints were in line with the requirements, similarity was all above 0.902, while the absorbance values were in the ranges of 0.693-0.781 (323 nm), 0.323-0.370 (267 nm), 0.957-1.067 (236 nm), 0.902-1.013 (226 nm), 0.953-1.075 (218 nm), and 0.926-1.052 (211 nm); In addition the expired nine batches of RI, similarity is less than 0.902 or the absorbance value does not meet the standard. Conclusion: UV fingerprint method can be used as a simple and accurate method of quality evaluation for the quality control of RI.

Alzheimer's disease (AD) is a common progressive degenerative disease of the central nervous system. It's also a main cause for dementia in presenium and senectitude. In the past few years, the discoveries in vitro expansion of neural stem cells (NSCs) indicate a new way for recovery and replacement of damaged neurons as well as reconstruction of the neural circuit, and offer a useful future therapy for AD. There are two main promising approaches in NSCs replacement therapy. They are endogenetic approach, inducing proliferation and differentiation of endogenetic NSCs, improving self-repair of central nervous system, and exogenous approach, ransplantation of exogenous tissue and promoting proliferation of endogenous NSCs. However, it may not become truth before the mechanism of NSCs' proliferation, migration, differentiation and it's integration with the host tissues to be elucidated.

Objective To investigate the clinical features,diagnosis and treatment of early postoperative inflammatory small bowel obstruction (EPISBO).Methods The results of 26 cases of EPISBO were analysed.Results 26 cases were all cured through gastroenteral decompression,somatostatin,TNP,dexamethasone and other medication in an average of 13.5 days.There was no reoperation.Conclusion EPISBO oftern occurs in 4～7 days after operation.EPISBO has the typical clinical features.Conservative treatment can cure EPISBO.

AIM: To observe the changes in contrast sensitivity (CS) between emmetropic pilots, glasses wearing, and after laser in situ keratomileuses ( LASIK) surgery pilots, provide the basis for the physical examination standard after operation.
METHODS:The CS of 13 emmetropic pilots (26 eyes), 12 glasses wearing pilots (24 eyes) and 10 with LASIK (20 eyes) , under photopic, scotopic and scotopic with glare environments at four different spatial frequencies ( 3, 6, 12 and 18cpd ) were measured and the resluts were analyzed by statistics.
RESULTS:Under photopic environments, there was no significant difference in the low spatial frequency (3cpd) among the three groups (P>0. 05). The CS of emmetropic pilots was better than that of the myopic and with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). Under scotopic environments, there was no significant difference in the low spatial frequency (3cpd)among the three groups (P>0. 05). The CS of emmetropic and with LASIK pilots were better than that of the myopic, and there was significant difference ( P<0.05). There was no significant difference in CS between emmetropic and with LASIK (P>0. 05). Under scotopic with glare environments, the CS of emmetropic and myopic pilots were better than that of the with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05).
CONCLUSION: The CS after LASIK is decreased compare with emmetropic pilot, specially under scotopic with glare environments. A perfect identification standard should be set up.

Objective:To explore the combined application effect of failure mode and effect analysis (FMEA) and root cause analysis (RCA) in IV infusion risk management of pediatric outpatient so as to enhance the quality of care and ensure the safety of outpatients.Methods: For this exploration, a special analysis team was established and the flowchart was drawn up, and the potential failure modes were listed by using FMEA. And the RCA was used to analyze and evaluate the key mode in these potential failure modes so as to find the root cause might affect the safety of IV infusion, and then the improved measures were implemented and the effects of new measurement were evaluated. Results:After implemented the improved measures, the risk of top 4 risk priority number (RPN) in intravenous infusion flow decreased obviously. For the transfusion management, patients' satisfaction increased from 78.09% to 95.03% (P<0.05), and nurses' satisfaction increased from 83.79% to 97.80%(P<0.05).Conclusion: The combined application of FMEA and RCA in the IV infusion risk management of pediatric outpatient can effectively reduce the occurrence of risk events, reduce nursing complaints and disputes, and enhance the quality of nursing care.
