Abstract
Objective: To investigate the overall efficacy of early breast cancer after breast-conserving treatment. To analyze risk factors affecting local regional recurrence (LRR), distant metastasis (DM) and survival. Methods: 1 791 breast cancer patients treated with breast-conserving surgery were retrospectively analyzed. The inclusion criteria were pathologic diagnosis of invasive breast cancer without supraclavicular and internal mammary node metastasis, T1-2N0-3M0, and no neoadjuvant therapy. Univariate analysis of survival was performed by Kaplan-Meier method and log rank test. Cox regression model was used for multivariate analysis. Results: The median follow-up time was 4.2 years. For all patients, the 5-year LRR, DM, disease-free survival(DFS) and overall survival(OS) rates were 3.6%, 4.6%, 93.0% and 97.4%, respectively. The LRR rates of patients with Luminal A, Luminal B1, Luminal B2, HER-2 over-expressed and triple-negative breast cancer were 2.0%, 6.1%, 5.9%, 0 and 10.0%, while the DM rates were 3.2%, 6.7%, 8.3%, 4.8% and 7.3%, respectively. Among the N0 patients, axillary dissection was performed in 689 cases and sentinel lymph node biopsy in 652 cases. The 5-year LRR rates were 3.3% and 3.2% (P=0.859), and the OS rates were 98.2% and 98.3% (P=0.311) respectively, which showed no statistically significant. There were 1 576 patients that underwent postoperative radiotherapy. Postoperative radiotherapy significantly reduced the 5-year LRR compared with surgery alone (2.5% vs 12.9%). The 5-year LRR rates of patients who received conventional fractionated radiotherapy and hypo-fractionated radiotherapy were 2.7% and 3.1%, respectively. But the difference was not statistically significant (P=0.870). Multivariate analysis showed that age, lymphovascular invasion, pathological T staging, postoperative radiotherapy, ER/PR status and endocrine therapy were independent factors of LRR in breast cancer patients (all P<0.05). Histological grade and pathological N staging were independent factors of DM (all P<0.05). The age, lymphovascular invasion, pathological T and N staging, postoperative radiotherapy, ER/PR status and endocrine therapy were independent factors for DFS (all P<0.05). Histological grade, pathological N staging, ER/PR status and endocrine therapy were factors for OS (all P<0.05). Conclusions: With contemporary standard treatment, the recurrence rate of early breast cancer after breast conserving treatment is less than 10%. Node-negative patients after sentinel lymph node biopsy did not need axillary dissection. The overall utilization of radiotherapy after breast conserving surgery is satisfactory. Hypofractionated radiotherapy is as effective as conventional fractionated radiotherapy. Local regional recurrence and distant metastasis have different risk factors.

Abstract
Objective: Primary gastric diffuse large B-cell lymphoma (PG-DLBCL) is the most common non-Hodgkin lymphoma (NHL) of extranodal origin. Most patients with PG-DLBCL had localized disease (stage Ⅰ or Ⅱ) at presentation, and will achieve complete response (CR) after induction chemotherapy. However, there has been little consensus regarding whether optimal treatment is provided by chemotherapy alone or chemotherapy plus radiotherapy, nor the treatment outcome from the addition of rituximab in localized-stage PG-DLBCL. Methods: Patients with Stage ⅠE and ⅡE PG-DLBCL were retrospectively analyzed. Patients have not undergone surgery, have received at least 3 cycles of R-CHOP or CHOP-like chemotherapy as initial therapy, and achieved CR or partial response (PR) were enrolled. Results: A total of 91 patients were studied. The median age was 51 years, included 47 males and 44 females. Fifty-two patients were at Stage ⅠE and 39 at Stage ⅡE, 64 (70.3%) patients received R-CHOP-like regimens, and 27 (29.7%) received CHOP-like regimens, the median chemotherapy cycle was 6 (3-8). Among the 91 patients, 80 (87.9%) patients achieved CR from induction chemotherapy, 11(12.1%) was evaluated PR. Of CR patients, 48 patients (60%) underwent consolidating radiotherapy and 32 patients (40%) did not receive radiotherapy; all PR patients received salvage radiotherapy. CR patients with and without radiation therapy had 4-year progression-free survival (PFS) rates of 96.4% and 96.7%, respectively (χ(2) = 0.546, P=0.46); 7/11 (63.6%) PR patients achieved CR after radiotherapy, with a median follow-up of 41 months, they were all disease free. For patients treated with R-CHOP or CHOP-like regimens, the 4-year PFS was 93.2% and 89.7%, respectively (χ(2)=0.096, P=0.757). Conclusions: Consolidation radiotherapy failed to improve the outcome for early-stage PG-DLBCL, while for PR patients, salvage radiotherapy increased CR rate and improved survival. The addition of rituximab to CHOP did not improve the efficacy.

Abstract
OBJECTIVE To evaluate the comprehensive technical efficiency of the tertiary public hospitals in Beijing between 2006 and 2015 and explore its influencing factors, so as to propose corresponding policy suggestions. METHODS The data envelopment analysis was employed to evaluate the comprehensive technical efficiency, pure technical efficiency and scale efficiency of the tertiary public hospitals in Beijing. Malmquist index model was used to analyze the changes of the above three dynamic efficiencies. Finally, randomeffect panel tobit model was utilized to analyze the influencing factors of the comprehensive technical efficiency. RESULTS The average comprehensive technical efficiency and pure technical efficiency of the tertiary public hospitals in Beijing were relatively high, and they had respectively increased from 0.44 and 0.51 in 2006 to 0.62 and 0.68 in 2015, and the highest proportion of two kinds of efficiency values was between 0.5 and 0.8. Most of the scale efficiency values distributed between 0.8 and 1.0, and the majority of hospitals were in a state of decreasing returns to scale. The total factor productivity of hospitals had been increasing at an average rate of 5.78% per year due to the double progress of technical efficiency and technology at annual rates of 3.77% and 1.94% respectively, further decomposing technological efficiency change, and the pure technical efficiency change increased at the speed of 3.21% per year, and the annual average rate of progress in scale efficiency was only 0.53%. The comprehensive technical efficiency was positively correlated with the turnover rate of beds, annual visits per doctor, the ratio of doctors to nurses, and negatively correlated with the number of beds, the ratio of outpatients to inpatients, the proportion of medical technical personnel, and the proportion of drugs. CONCLUSION Future health policies should strictly control the scale of tertiary public hospitals, pay attention to the innovation and application of hospital technology, change the hospital internal management level and management model, promote refined management, and achieve sustainable development.

Abstract
Objective: To analyze the clinical features and prognosis of the ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery. Methods: From 1999 to 2013, 63 women with IBTR after breast conserving surgery were retrospectively reviewed. All patients had adequate information on tumor location both at first presentation and at recurrence, with or without regional recurrence or distant metastasis. The histologic changes between true local recurrence and elsewhere recurrence groups were compared. The local recurrence, the overall survival after IBTR (IBTR-OS), the disease-free survival after IBTR (IBTR-DFS) were also compared. Results: All patients had undergone lumpectomy, including 38 cases with additional axillary lymph node dissection and 13 cases with sentinel lymph node biopsy. There were 11.3% (7/63) cases received neoadjuvant systemic therapy, 68.3% (43/63) had adjuvant radiotherapy, 60.3% (38/63) underwent adjuvant chemotherapy and 47.6% (30/63) received hormonal therapy. Forty-five cases (71.4%) had recurrence in the same quadrant, and 18 cases (28.6%) had elsewhere recurrence. Compared with histology at presentation, 10.3% of the patients (6/58) had different ones at recurrence and 28.9% of patients (13/45) had different molecular subtypes. The conversion rate of estrogen receptor status (33.3% vs 9.5%, P=0.012) and progesterone receptor status (56.3% vs 19.0%, P=0.005) in patients with elsewhere recurrence was significantly higher than that in patients with same quadrant recurrence. Fifty-nine cases had undergone surgery after IBTR, with 48 cases of secondary breast-conserving surgery and 11 cases of salvage mastectomy. The median time to IBTR of same quadrant recurrence and elsewhere recurrence groups were 26 months and 62 months (P=0.012), respectively. There were 84.4% and 44.4% cases who had local recurrence within 5 years after breast conserving surgery, respectively. Of all cases, the overall 5-year IBTR-OS and 5-year IBTR-DFS rates were 79.4% and 60.4%, respectively. There were no significant differences in 5-year IBTR-OS (77.4% vs. 83.6%, P=0.303) or 5-year IBTR-DFS (60.0% vs. 62.8%, P=0.780) between same quadrant recurrence and elsewhere recurrence groups. Univariate analysis showed that pN0-1 (P<0.001), luminal subtype (P=0.026), adjuvant endocrine therapy (P=0.007) at first presentation, recurrent tumor < 3 cm (P=0.036) and having surgery after IBTR(P=0.002) were favorable factors of IBTR-OS. pN0-1 (P<0.001) at first presentation, recurrent tumor stage Ⅰ-Ⅱ (P<0.001) and having surgery after IBTR(P=0.001) were favorable factors of IBTR-DFS. There was no significant difference between second breast-conserving surgery and salvage mastectomy in IBTR-OS and IBTR-DFS (P>0.05). Conclusions: The IBTR after breast conserving surgery mainly occurred at the original quadrant. Second breast-conserving surgery did not affect patient's prognosis. There were significant differences in biological features between the same quadrant recurrence and elsewhere recurrence, requiring different therapeutic strategies in the future.

Abstract
Objective: To conduct a follow-up investigation of structural changes of the corpus callosum fibers of toddlers (2 to 5 years of age) with autism spectrum disorder(ASD) and to explore the associations with clinical symptoms. Method: In this prospective randomized controlled study, ASD children who were diagnosed in the Child Mental Health Research Center, Nanjing Brain Hospital Affiliated to Nanjing Medical University from May 2011 to November 2012 were included in the ASD group, and developmentally delayed children were included in the control group (DD group). Diffusion tensor imaging (DTI) data from the two groups were obtained at two age levels: 2-3 years of age, and 4-5 years of age. Region of interest analysis was applied to assess characteristic values of total area and sub-regions of corpus callosum: the fraction anisotropy (FA), the mean diffusivity (MD), the radial diffusivity (RD) and the axial diffusivity (AD). All children were assessed using the Autism Diagnostic Interview-Revised (ADI-R) and Autism Treatment Evaluation Checklist (ATEC). The characteristic values of total area and sub-regions of corpus callosum of ASD group at two age levels were analyzed by paired sample t test; the characteristic values of total area and sub-regions of corpus callosum of ASD group and DD group were analyzed by independent-sample t test; the correlations between FA values of the total area and sub-regions of corpus callosum and ADI-R or ATEC scores were analyzed by Pearson correlation analysis. Result: Forty cases meeting inclusion criteria were enrolled in ASD group, and 31 eligible cases were enrolled in the control group. Four children in the ASD group were lost to follow-up, and 5 children in the control group were lost to follow-up. Longitudinal comparison between the two age subgroups of ASD patients showed that the FA values of the total corpus callosum increased (0.499 55±0.027 59 vs. 0.505 83±0.086 64, t=4.88, P<0.05), but MD values, RD values and AD values of the total corpus callosum area decreased (0.000 89±0.000 03 vs. 0.000 81±0.000 14, 0.000 61±0.000 04 vs. 0.000 55±0.000 09, 0.001 43±0.000 03 vs. 0.001 38±0.000 03, t=9.31, 7.90, 8.66, P<0.05 for all comparisons). In the area of corpus callosum genu, FA and AD values increased (t=5.59, 8.48, P<0.05 for both comparisons), but MD and RD values decreased (t=12.67, 11.28, P<0.05 for both comparisns). In the area of corpus callosum body, FA and RD values increased(t=5.46, 8.48, P<0.05 for both comparisons), but MD and AD values decreased (t=8.08, 6.22, P<0.05 for both comparisons). In the area of corpus callosum splenium, MD, RD and AD values decreased (t=6.81, 4.44, 5.51, P < 0.05 for all comparisons). Among the participants 2 to 3 years of age, there were no significantly differences in FA values of total area and sub-regions of corpus callosum between ASD group and the DD group (P > 0.05 for all comparisons); as compared with the DD group, ASD group had higher AD values of total area and splenium of corpus callosum (0.001 43±0.000 03 vs. 0.001 40±0.000 04, 0.001 34±0.000 03 vs. 0.001 32±0.000 04, t=1.56, 1.14, P < 0.05 for both comparisons); ASD group had lower AD values but higher RD and MD values of corpus callosum genu (t=0.07, 0.55, 0.07, P < 0.05 for all comparisons); ASD group had lower RD values of corpus callosum body (t=0.07, P < 0.05). Among the participants 4 to 5 years of age, as compared with the DD group, ASD group had higher FA value of total corpus callosum area(0.505 83±0.086 64 vs. 0.483 77±0.099 30, t=8.56, P < 0.05), lower RD value of total corpus callosum(0.000 55±0.000 09 vs. 0.000 56±0.000 12, t=14.44, P < 0.05), lower RD values of corpus callosum body (t=2.20, P < 0.05), higher FA values (t=3.35, P < 0.05) but lower AD values of corpus callosum splenium (t=2.20, P < 0.05). A correlation analysis between FA values of total area and sub-regions of corpus callosum and clinical variables showed that the FA values of total area and splenium of corpus callosum in ASD group at 2 to 3 years of age were negatively correlated with the scores of language skills in ATEC (r=-0.35,-0.36, P < 0.05 for both comparisons). And after two years, FA values of total corpus callosum were positively correlated with the scores of social communication in ATEC (r=0.34, P < 0.05). There was no significant correlation between FA values of sub-regions of corpus callosum and the scores of ATEC (P > 0.05 for all comparisons). There was no significant correlation between FA values of total area and sub-regions of corpus callosum and the scores of ADI-R (P > 0.05 for all comparisons). Conclusion: The fiber structure of corpus callosum was still in the process of maturing during the age of 2 to 5 years; however, compared with DD group, ASD group had more extensive structural abnormalities of the corpus callosum fibers as age increased, and the structural abnormalities had correlation with the core symptoms of ASD.

Abstract
BACKGROUND This phase I/II clinical trial investigated S-1 administered with intensity-modulated radiotherapy (IMRT) as adjuvant therapy for node-positive gastric cancer. Patients had undergone radical resection and D1/D2 lymph node dissection. METHODS In phase I, patients received adjuvant chemoradiotherapy of IMRT (45 Gy in 25 fractions) with concurrent S-1 administered on a dose-escalation schedule to determine the recommended dose (RD). In phase II, the safety and efficacy of the RD of S-1 combined with IMRT were assessed. RESULTS We consecutively enrolled 73 patients (56 men; median age, 53 years; range, 29-73 years) and the phase I portion of the study included 27 patients. The RD of S-1 administered concomitantly with IMRT was 80 mg m-2 day-1 orally, twice daily. The phase II analysis included 52 patients (46 new patients plus 6 from phase I). 8 patients (15.4%) developed grade 3 or 4 toxicities. There were 21 recurrence events and 15 deaths (1 bowel obstruction, 14 gastric cancer). Three-year disease-free survival and overall survival were 62.2% (95% confidence interval (CI), 48.5-75.9) and 70.0% (95% CI, 56.3-83.7), respectively. The median time to recurrence was 17.5 months (range, 3.8-42.0). The median time from recurrence to death was 7.0 months (range, 1.5-28.7). CONCLUSIONS S-1 combined with IMRT adjuvant chemoradiotherapy is safe and efficacious for advanced gastric cancer.

Abstract
Objective: To determine the most cost-effective modality for breast cancer screening in women living in Shanghai. Methods: A Markov model for breast cancer was redeveloped based on true effect which was derived from a project for detection of women at high risk of breast cancer and an organized breast cancer screening program conducted simultaneously in Minhang district, Shanghai, during 2008 to 2012. Parameters of the model were derived from literatures. General principles related to cost-effectiveness analysis were used to compare the costs and effects of 12 different screening modalities in a simulated cohort involving 100 000 women aged 45 years. Incremental cost-effectiveness ratio (ICER) was used to determine the most cost-effective modality. Sensitivity analysis was conducted to evaluate how these factors affected the estimated cost-effectiveness. Results: The modality of biennial CBE followed by ultrasonic and mammography among those with positive CBE was observed as the most cost-effective one. The costs appeared as 182 526 Yuan RMB per life year gained and 144 386 Yuan RMB per quality adjusted life-year (QALY) saved, which were within the threshold of 2-3 times of local per capita Gross Domestic Product. Results from sensitivity analysis showed that, due to higher incidence rate of breast cancer in Shanghai, the cost per QALY would be 64 836 Yuan RMB lower in Shanghai than the average level in China. Conclusion: Our research findings showed that the biennial CBE program followed by ultrasonic and mammography for those with positive CBE results might serve as the optimal breast cancer screening modality for Chinese women living in Shanghai, and thus be widely promoted in this population elsewhere.

Abstract
Objective: To establish a risk-adapted postmastectomy radiotherapy strategy based on local-regional recurrence for intermediate-risk breast cancer (T1~2N1M0 stage). Methods: A total of 2413 patients with T1-2N1M0 breast cancer were retrospectively reviewed. Of them, 588 patients (24.4%) received postmastectomy radiotherapy (PMRT), while 1 825 (75.6%) patients did not. A comprehensive comparative study was performed by using multivariable and propensity score-matched (PSM) analyses. Results: The median follow-up time was 67.0 months, the 5-year local region recurrence free-survival (LRRFS), disease-free survival (DFS) and overall survival (OS) were 93.8%, 85.7% and 93.3%, respectively. The 5-year local region recurrence (LRR) was 6.1%. For patients without PMRT, multivariable analysis indicated that age, tumor localization, molecular subtype, pathologic T stage and number of positive lymph node were independent factors for LRRFS (all of P<0.05). Patients with T1-2N1 breast cancer were classified into low-risk group (0-1 risk factor, 768 patients), intermediate-risk group (2 risk factors, 690 patients) and high-risk groups (≥3 risk factors, 544 patients) based on the five independent factors mentioned above. The 5-year LRRFS, DFS and OS were significantly different among the three groups (P<0.001). In low- and intermediate-risk groups, there were no significant differences in LRRFS, DFS and OS of patients who received PMRT or not (P>0.05). In high-risk group, the DFS of patients received PMRT or not were 79.8% and 74.4%, respectively (P=0.127), the OS of them were 86.8% and 87.1%, respectively (P=0.174), and the LRRFS were 93.3% and 84.3%, respectively (P=0.002). After PSM adjustment, no significant differences in LRRFS, DFS and OS were observed between PMRT-received subgroup and no PMRT subgroup of low-risk group (P>0.05). In intermediate-risk group, the LRRFS of patients received PMRT or not were 95.2% and 91.0%, respectively (P=0.037). However, in the high-risk group, the LRRFS, DFS and OS of patients received PMRT were 93.3%, 79.7% and 86.6%, respectively, while those of patients did not receive PMRT were 78.5% (P<0.001), 69.5% (P=0.038) and 85.7% (P=0.080), respectively. Conclusions: The local-regional recurrence risks of patients with pT1-2N1 breast cancer are viable and risk-adapted PMRT is available for them. Better prognoses can be achieved by the patients of intermediate and high-risk group. More samples on this subject are needed to validate the results.

Abstract
Objective: To investigate the value of preoperative dynamic contrast-enhanced MRI in reducing the rate of tumor-positive resection margins after breast conserving surgery in patients with early non-mass breast carcinoma. Methods: Seventy-two patients with early non-mass breast carcinoma received ultrasonographic and mammographic examination and subsequently underwent dynamic contrast-enhanced MRI examination before breast conserving surgery. The control group consisted of 74 patients who had early non-mass breast carcinoma. They only received ultrasonographic and mammographic examination and didn't undergo contrast-enhanced MRI examination. The comparison of the rate of tumor-positive resection margins between two groups was performed. The MRI findings that had the significant influence on the rate of tumor-positive resection margins were analyzed using Logistic regression model. Results: In 28 patients (28/72, 38.9%), dynamic contrast-enhanced MRI could correct or supplement the ultrasonographic and mammographic findings and resulted in the reasonable change of surgical program. The preoperative MRI examination group (n=30) had lower rate of tumor-positive resection margins than control group for invasive ductal carcinoma (23.3% vs 40.0%, P=0.02), but there was no significant difference (21.4% vs 26.9%, P=0.10) between two groups for ductal carcinoma in situ (n=28). The preoperative MRI examination group (n=14) had lower rate of tumor-positive resection margins than control group for the other pathologic types of breast carcinoma (14.3% vs 38.9%, P=0.02). The statistical analysis on the basis of Logistic regression model showed that some main MRI findings, including change surrounding the tumor, distance between tumor and nipple and tumor size, had the significant influence on the rate of tumor-positive resection margins. Conclusion: Preoperative dynamic contrast-enhanced MRI significantly increased the accuracy of resection margins evaluation, and greatly reduced the rate of tumor-positive resection margins after breast conserving surgery in patients with early non-mass breast carcinoma.

Abstract
BACKGROUND Tissue transglutaminase (tTG) immunoglobulin A (IgA) testing is a sensitive adjunct to the diagnosis of coeliac disease. The threshold for positivity was developed for diagnosis, with negative results reported as below the reference value (<4 U/mL). AIM To investigate if an undetectable (tTG IgA<1.2 U/mL) is more predictive of healing compared to patients with negative but detectable serology (1.2-3.9 U/mL). METHODS We performed a retrospective study of 402 treated coeliac disease patients seen at the Mayo Clinic with negative tTG IgA values drawn within 1 month of duodenal biopsy between January 2009 and December 2015. The Corazza-Villanacci score was used to assess mucosal healing. The presence of gastrointestinal symptoms was also collected. Logistic regression was used to assess the relationship of clinical variables with a normal biopsy. RESULTS Patients with undetectable titres more frequently had normal duodenal histology compared to patients with detectable tTG IgA levels (117/240 vs. 53/162; OR=1.96; 1.292, 2.961). Asymptomatic patients more frequently had normal duodenum as compared to symptomatic patients (88/163 vs. 82/239; OR=2.25; CI: 1.494, 3.377). Patients with undetectable serology and on a gluten-free diet for ≥2 years were more likely to have no villous atrophy compared to patients with detectable serology (148/192 vs. 55/88; OR=2.02; CI: 1.17, 3.49). CONCLUSION In subjects recovering from coeliac disease with negative tTG IgA serology, an undetectable titre is associated with normal histology on follow-up biopsy.

Abstract
Cystic echinococcosis (CE) caused by the cestode Echinococcus granulosus (E. granulosus) is a zoonotic parasitic disease. The effective immune evasion mechanisms of E. granulosus allow it to parasitize its hosts. However, the status of the innate and adaptive immune cells and their contributions to E. granulosus progression remain poorly understood. In this study, we aimed to determine the impact of E. granulosus infection on T cells, NK cell responses and TGF-β expression during the early infection phase in BALB/c mice. In E. granulosus infections, there was an increasing tendency in the percentage of CD4+ CD25+ T cells and CD4+ Foxp3+ T cells and peripheral blood TGF-β levels and relative expression of the Foxp3 gene. Moreover, there were a decreasing tendency in the percentage of NK cells and NK cell cytotoxicity and the expression of NKG2D on NK cells. The TGF-β1/Smad pathway was activated by E. granulosus in mice. Above results can be reversed by the inhibitor SB-525334 (potent activin receptor-like kinase 5 inhibitor). These results suggest that the TGF-β/Smad pathway plays an important role in changes of T-cell or NK cell responses. These results may contribute to revealing the preliminary molecular mechanisms in establishing hydatid infection.

Abstract
Objective: To analyze the outcomes of clinical T1-3N1M0 breast cancer patients with pathological negative axillary lymph nodes (ypN0) after neoadjuvant chemotherapy (NAC) and mastectomy, and investigate the role of postmastectomy radiotherapy (PMRT). Methods: A total of 185 patients with clinical T1-3N1M0 breast cancer treated between 1999 and 2013 were retrospectively reviewed. All patients were treated with NAC and mastectomy, and achieved ypN0. Of them, 89 patients received additional PMRT and 96 patients did not. 101 patients had clinical stage Ⅱ disease. 84 patients had clinical stage Ⅲ disease. The rates of locoregional recurrence (LRR), distant metastasis (DM), disease-free survival (DFS), and overall survival (OS) were calculated using the Kaplan-Meier method, and differences were compared using the log-rank test. Univariate analysis was used to interpret the impact of clinical features and treatment on patients' outcome. Results: The 5-year rates of LRR, DM, DFS, and OS for all patients were 4.5%, 10.4%, 86.6%, and 97.1%, respectively. For patients with and without PMRT, the 5-year LRR rates were 1.1% and 7.5% (P=0.071), the 5-year DM rates were 5.1% and 15.0% (P=0.023), the 5-year DFS rates were 95.0% and 79.0% (P=0.008), and the 5-year OS rates were 100.0% and 94.5% (P=0.089) respectively. In univariate analysis, lymph-vascular space invasion (LVSI) was poor prognostic factor of LRR (P=0.001), < 40 years old and lack of PMRT was a poor prognostic factor for DM (P<0.05), lack of PMRT was a poor prognostic factor for DFS (P=0.008), primary lesion residual and mild-moderate pathological response to NAC were poor prognostic factors for OS (P<0.05). In the subgroup of Stage Ⅲ disease, for patients with and without PMRT, the 5-year LRR rates were 1.9% and 14.4% (P=0.041), the 5-year DFS rates were 91.9% and 67.4% (P=0.022), respectively. In the subgroup of Stage Ⅱ disease, for patients with and without PMRT, the 5-year DM rates were 0 and 11.5% (P=0.044), the 5-year DFS rates were 100.0% and 84.9% (P=0.023), respectively. Conclusions: The LRR rate of clinical T1-3N1M0 breast cancer patients who achieved ypN0 after NAC and mastectomy was low. PMRT decreased the DM rate and increased DFS rate in all patients, and significantly decreased the LRR rate in Stage Ⅲ disease. PMRT should be considered for patients with Stage Ⅲ disease, and further research is warranted to investigate the benefit of PMRT for Stage Ⅱ disease.

Abstract
This study proposed a decision tree model to screen upper urinary tract damage (UUTD) for patients with neurogenic bladder (NGB). Thirty-four NGB patients with UUTD were recruited in the case group, while 78 without UUTD were included in the control group. A decision tree method, classification and regression tree (CART), was then applied to develop the model in which UUTD was used as a dependent variable and history of urinary tract infections, bladder management, conservative treatment, and urodynamic findings were used as independent variables. The urethra function factor was found to be the primary screening information of patients and treated as the root node of the tree; Pabd max (maximum abdominal pressure, >14 cmH2O), Pves max (maximum intravesical pressure, ≤89 cmH2O), and gender (female) were also variables associated with UUTD. The accuracy of the proposed model was 84.8%, and the area under curve was 0.901 (95%CI=0.844-0.958), suggesting that the decision tree model might provide a new and convenient way to screen UUTD for NGB patients in both undeveloped and developing areas.

Abstract
OBJECTIVE Articular chondrocyte activation, involving aberrant proliferation and prehypertrophic differentiation, is essential for osteoarthritis (OA) initiation and progression. Disruption of mechanistic target of rapamycin complex 1 (mTORC1) promotes chondrocyte autophagy and survival, and decreases the severity of experimental OA. However, the role of cartilage mTORC1 activation in OA initiation is unknown. In this study, we elucidated the specific role of mTORC1 activation in OA initiation, and identify the underlying mechanisms. METHOD Expression of mTORC1 in articular cartilage of OA patients and OA mice was assessed by immunostaining. Cartilage-specific tuberous sclerosis complex 1 (Tsc1, mTORC1 upstream inhibitor) knockout (TSC1CKO) and inducible Tsc1 KO (TSC1CKOER) mice were generated. The functional effects of mTORC1 in OA initiation and development on its downstream targets were examined by immunostaining, western blotting and qPCR. RESULTS Articular chondrocyte mTORC1 was activated in early-stage OA and in aged mice. TSC1CKO mice exhibited spontaneous OA, and TSC1CKOER mice (from 2 months) exhibited accelerated age-related and DMM-induced OA phenotypes, with aberrant chondrocyte proliferation and hypertrophic differentiation. This was associated with hyperactivation of mTORC1 and dramatic downregulation of FGFR3 and PPR, two receptors critical for preventing chondrocyte proliferation and differentiation. Rapamycin treatment reversed these phenotypes in KO mice. Furthermore, in vitro rescue experiments demonstrated that p73 and ERK1/2 may mediate the negative regulation of FGFR3 and PPR by mTORC1. CONCLUSION mTORC1 activation stimulates articular chondrocyte proliferation and differentiation to initiate OA, in part by downregulating FGFR3 and PPR.

Abstract
Objective: To evaluate the prognostic value of sequencing of adjuvant radiotherapy and chemotherapy following breast-conserving surgery for patients with breast cancer. Methods: A total of 1 154 patients withT1-2N0-3M0 breast cancer retrospectively reviewed. All patients received sequential radiotherapy and chemotherapy following breast-conserving surgery. Among them, 603 patients received radiotherapy first and 551 patients received chemotherapy first. Log-rank tests were used to determine significance of disease-free survival (DFS) and overall survival (OS) rates in the Kaplan-Meier curve. Results: The 5-year DFS and OS rates for all patients were 93.0% and 97.8%. The 5-year OS rate was 98.6% in the radiotherapy first group and 96.4% in the chemotherapy first group (P=0.191), and the corresponding DFS rate was 92.7% and 93.2% (P=0.430), respectively. Among the patients with Luminal A subtype, the 5-year OS rate was 99.6% in the radiotherapy first group and 97.8% in the chemotherapy first group (P=0.789). Among the patients with Luminal B subtype, the 5-year OS rate was 94.2% and 96.0%, respectively (P=0.680). Among the patients with triple negative breast cancer, the 5-year OS rate was 100% and 90.9%, respectively, with statistically significant differences (P=0.019). Among the patients with HER-2 positive breast cancer, The 5-year DFS rate was 80.1% and 100%, respectively (P=0.045). Conclusions: The OS and DFS rates in the chemotherapy first group are not significantly different from those of radiotherapy first group after breast-conserving surgery. Patients with HER-2 positive breast cancer in chemotherapy first group have a much higher DFS rate than that of radiotherapy first group, whereas patients with triple negative breast cancer in radiotherapy first group have a better OS rate than that of chemotherapy first group. Further research is warranted to investigate the benefit of different molecular types in different sequencing of radiotherapy and chemotherapy after breast-conserving surgery.

Abstract
OBJECTIVE Analyze clinical use of dexmedetomidine to relieve prognosis of remifentanil anesthesia recovery and analyze intervention effect. MATERIALS AND METHODS Choose 3600 cases of cerebral functional area operation patients treated in different hospitals during June 2011 and December 2015 for general analysis, group the patients by considering relevant parting of anesthesia recovery by American Society of Anesthesiologists, and divide the patients into dexmedetomidine group and control group according to different use of drugs. The two groups of patients are anesthetized, patients' anesthesia wake-up time and wake-up success rate are recorded, and effect of two types of anesthesia wake-up way are compared. RESULTS There exists no significant statistical difference in wake-up success rate of the two groups of patients, wake-up time has small difference, but anesthesia recovery quality of dexmedetomidine group is higher, which is conducive to physical rehabilitation of patients and minimize the effects of anesthetics on patients. CONCLUSION In clinical surgery, after use of remifentanil anesthesia on patients, use of dexmedetomidine for anesthesia recovery can minimize adverse effects of drugs on patients and thus is worthy to be effectively promoted in clinics.

Abstract
Mapping a set of categorical values to different colors is an elementary technique in data visualization. Users of visualization software routinely rely on the default colormaps provided by a system, or colormaps suggested by software such as ColorBrewer. In practice, users often have to select a set of colors in a semantically meaningful way (e.g., based on conventions, color metaphors, and logological associations), and consequently would like to ensure their perceptual differentiation is optimized. In this paper, we present an algorithmic approach for maximizing the perceptual distances among a set of given colors. We address two technical problems in optimization, i.e., (i) the phenomena of local maxima that halt the optimization too soon, and (ii) the arbitrary reassignment of colors that leads to the loss of the original semantic association. We paid particular attention to different types of constraints that users may wish to impose during the optimization process. To demonstrate the effectiveness of this work, we tested this technique in two case studies. To reach out to a wider range of users, we also developed a web application called Colourmap Hospital.

Abstract
Aims Resistin has been reported to impair the pancreatic beta cells and associated with insulin resistance. MicroRNAs (miRNAs) are short, endogenously produced non-coding ribonucleotides that bind mRNAs and function mainly as negative regulators in mammals. MiRNAs have been implicated in many diseases, including insulin resistance and diabetes. A considerable body of evidence has indicated an important function for miRNAs in insulin secretion. The current study was designed to investigate the effects of miR-494 in the reductions in insulin secretion attributable to resistin. Methods Insulin secretion was determined by ELISA, and expressions of genes were identified using quantitative RT-PCR (qRT-PCR) or Western blot analysis. Results Insulin secretion was significantly reduced by resistin. Overexpression of miR-494 inhibited insulin secretion both in diet culture and high glucose medium in MIN6 cell lines. MiR-494 down-regulated the protein level of STXBP5 by pairing with sites in the 3'UTR. Conclusion miR-494 is involved in the insulin secretion regulated by resistin via its effects on STXBP5 in MIN6 cells.
