As a milestone in the development of personalized comprehensive treatment for breast cancer, molecular subtype classification quantitatively characterizes breast cancer as heterogeneous diseases rather than a single disease in terms of onset risk, natural course, and treatment response. The significance of molecular subtype classification has been widely confirmed in prediction of the efficacy of systemic treatment and prognosis of systemic metastases and risk of death. However, the association between molecular subtype and local?regional recurrence ( LRR) risk as well as the impact of molecular subtype classification on radiotherapy strategy still needs more attention. This review discusses the association between molecular subtype and LRR risk as well as the significance of molecular subtype classification in guiding radiotherapy strategy.

With the widespread adoption of screening mammography, the incidence of ductal carcinoma in situ (DCIS) has been dramatically increased. The spectrum of local treatment advances from mastectomy to breast conservation surgery plus whole breast irradiation (WBI), and hypofractionated WBI or accelerated partial breast irradiation. Although the efficacy of WBI on reducing local recurrence is clear, such benefit in the low-risk DCIS is still controversial. Further studies are required to establish a more precise local recurrence risk stratification system for better tailoring local treatment in patients with DCIS. In this review, the latest advances and controversies in surgery, radiation therapy and local recurrence risk stratification system for patients with DCIS were summarized.

This paper is to report our study in which the differences between prosthetic restoration and surgical reconstruction using traditional clasp retention technology were analyzed based on three-dimensional finite element methods in our laboratory. Firstly, the maxillary unilateral defect model was developed using medical image processing software MIMICS. Secondly, the prosthesis was generated by mirroring technology. The clasp was designed according to the methods raised by Aramany. Then, the stress distribution of maxilla was calculated by simulating occlusion. According to the results, after osseointegration of surgical reconstruction, stresses of unaffected abutments were reduced significantly, and less stress of junction occurred near zygoma of affected side, which were all less than stresses of prosthesis restoration. Thus, removing the clasp of surgical reconstruction increased the stresses of unaffected abutments. The stress trends of maxillary components were different between prosthetic restoration and surgical reconstruction. Surgical reconstruction is better than prosthesis restoration in protection of the abutments. Clasp can alleviate the occlusal burden of maxilla. Varieties of retentive technologies can be considered in prosthesis restoration. The surgical reconstruction is more conducive to rehabilitate unilateral maxilla biomechanically in clinic.

Objective:To observe the effect of Aalv Capsule on sodium current in guinea pig ventricular myocytes(INa)for exploring the mechanism of its anti-premature beats.Methods:Whole-cell patch-clamp recording technique was used to record the Aalv Capsule for a single cell of sodium currents in guinea pig ventricular myocytes.Results:There was dose-dependent of Aalv Capsule in block of sodium currents and had a certain amount of use-dependent and time-dependent.Conclusion:The role of Aalv Capsule in blocking sodium current block was one of the mechanisms of its in bearing premature.

Aim To evaluate whether the combination of polypeptide AP25 and docetaxel is more efficient in treating experimental breast cancer,than either reagent used alone,and to offer suggestions for clinical use. Methods An experimental breast carcinoma model was set up to investigate the anti-tumor effects of AP25 and docetaxel combination.The Q value was caluculat-ed by Guinness rules and the anti-tumor effects of the combination of polypeptide AP25 and docetaxel were e-valuated.Results The treatment by the combination of polypeptide AP25 and docetaxel showed a better tumor inhibition rate.The combination of AP25 20 mg ·kg -1 and docetaxel 10 mg·kg -1 significantly inhibi-ted the tumor growth with 0.85 1.15,showing a synergistic effect.Conclusions The combination of AP25 and docetaxel can significantly in-hibit the tumor growth with a synergistic effect and de-crease the dose of chemotherapy.

Objective: To evaluate the self-developed intelligent assist order system for parenteral nutrition on the control of concentration exceeding standard of positive ions.Methods: The special comments, pharmacist audit and information control were used to intervene the concentration exceeding standard of positive ions in parenteral nutrition orders and the effect of the three intervention methods were evaluated.Results: For the intervention of concentration exceeding standard of positive ions in parenteral nutrition orders, the information control was better than the special comments and pharmacists audit.Conclusion: The intelligent assist order system for parenteral nutrition can solve the problem of concentration exceeding standard and promote the rational application of parenteral nutrition in hospitals.

Objective To discuss the accuracy and objectivity of student standardized patients (SSP) in objective structured clinical examination(OSCE). Methods On March 30 and 31, 2013, 168 seven-year program medical students of class 2006 and 2007 took part in OSCE. Differences in as-sessment results between SPP and those given by professional doctors at 3 SP sites(angina pectoris SSP station, acute cholecystitis SSP station, depression SSP station) were analyzed. Each site had 4 items for assessment, with a total score of 100. Scores were given in strict accordance with a set of unified scoring rules. Counting data were presented as x±s. Data were verified using t test. P<0.05 was considered statis-tically considerable. Results At angina pectoris station, respective scores of SSP and professional physi-cians were 85.2±7.1 and 85.5±6.6, P=0.688. At acute cholecystitis station, respective score of SSP and professional physicians were 89.1±5.2 and 88.2±6.2, P=0.150. At depression station, respec-tive score of SSP and professional physicians were 79.8±7.5 and 78.2±7.0, P=0.078. Conclusion There is no statistical difference between scores given by SSP and those given by the physicians in OSCE. This proves that SSP who received standardized training delivers fair and accurate results in OSCE , and therefore is recommended for future application.

Objective:To evaluate the effects of periodontitis on the expression of apoptosis-related proteins in pancreas of rats with Type 2 Diabetes Mellitus.Methods:Spontaneously type 2 diabetic OLETF rats were randomly divided into 2 groups:diabetes with or without periodontitis(diabetes group and combination group).LETO rats with the same germline and the same age but having normal glucose tolerance were randomly divided into control group and periodontitis group.20 weeks after periodontitis were established,all the rats were sacrificed and the pancreas were pathologically examined by HE staining.The expression of Bax,Bcl-2 and Caspase-3 in the pancreas islet were detected by immunohistochemistry staining and semi-quantitative analysis.Results:The expression of Bax, Bcl-2 and Caspase-3 in the pancreas islet was no significant difference between control and periodontitis groups(P=0.324,P=0.091,P=0.852).Compared with diabetes group,the expression of Bax and Caspase-3 in combination group showed a significant increase(P=0.000,P=0.000),and the expression of Bcl-2 was significantly decreased(P=0.022).Conclusion:Under healthy conditions,periodontitis has no effect on the expression of apoptosis-related proteins in rat pancreas islet.However,in rats with diabe-tes,periodontitis may affect the expression of apoptosis-related proteins in pancreas islet.
