Abstract
Malignant phyllodes tumor (MPT) which belong to the fibroepithelial neoplasm spectrum is a rare type of breast malignancy, and currently there is no effective targeted approach available for MPT. In this study, we tried to identify key genomic alterations and biologic pathways in MPT by whole exome and RNA sequencing of nine MPT tissues. Whole exome sequencing revealed somatic alterations in EGFR, MED12, PIK3CA, PIK3R1, PDGFRA, PDGFRB, PTEN, and TP53. Transcriptome sequencing showed dysregulation of ECM-receptor interaction, focal adhesion, and PI3K-Akt signaling in MPTs when compared to normal breast or invasive breast cancer tissues. Based on the transcriptome profiles, the MPTs were classified into two subtypes; fibrous subtype with upregulation of stromal genes such as collagens and epithelial subtype with upregulation of E-cadherin and Claudins. The molecular classification of fibrous and epithelial subtypes was validated in 28 paraffin-embedded MPT tissues. The fibrous subtype showed higher mitotic index and increased risk for recurrence when compared to the epithelial subtype. We established a patient-derived xenograft model from one fibrous subtype MPT which harbored somatic mutation in PIK3R1 and PDGFRB. In that model, targeted treatment against PIK3CA/mTOR and PDGFR pathways effectively suppressed the tumor growth in vivo. Our data provide insights on the biologic understanding of MPT and suggest a clinically relevant molecular classification. Furthermore, we show that developing effective targeted approaches in MPT can be possible with genomic profiles and patient-derived xenograft models. The clinical efficacy of targeting PDGFR and PIK3CA/mTOR pathways in MPT should be tested in future clinical trials.

Abstract
Abstract
Background: According to the American College of Surgeons Oncology Group Z0011 trial, complete axillary lymph node dissection (ALND) did not affect survival of patients with clinical T1-T2 invasive breast cancer and one to two sentinel lymph nodes (SLNs) metastases treated with lumpectomy, adjuvant systemic therapy, and radiation therapy. A significant proportion of breast cancer patients may not require ALND, in whom intraoperative analysis of SLNs can be omitted reducing operation time and cost. The aim of this study was to develop a nomogram predicting three or more axillary lymph nodes (ALNs) metastases based on preoperative imaging and clinicopathological factors.
Methods: The training set consisted of 1030 patients with clinical T1-T2 invasive breast cancer and clinically negative ALN who received surgery at Seoul National University Hospital (SNUH) between January 2010 and December 2013. Preoperative imaging techniques including ultrasonography (US), computed tomography (CT), positron emission tomography (PET), and clinicopathological features associated with three or more ALN metastases were evaluated by logistic regression analysis. A nomogram predicting three or more ALNs was developed with statistically significant factors. The validation set consisted of 781 independent patients who received surgery at SNUH between January 2014 and December 2015.
Results: Of the 1030 patients, 89 (8.6%) had three or more ALN metastases. Multivariate analysis showed that three or more ALN metastases was independently associated with tumor size (cm) by US (p<0.001), suspicious ALNs findings in US (p<0.001), chest CT (p<0.001), and PET/CT (≥ 1.4 SUV, p<0.001). Established nomogram evaluating the probability of three or more ALNs metastases includes the above four associated factors. The areas under the receiver operating characteristic (ROC) curve of the nomogram were 0.866 (95% confidence interval [CI] 0.826-0.905) for the training set and 0.867 (95% CI: 0.801-0.932) for the validation set. With cutoff point of 142, false negative ratio is 3.6%, and 8.6% of patients were candidates for intraoperative SLN analysis.
Conclusion: Patients with a strong possibility of three or more ALNs metastases can be identified using preoperative imaging methods including US, CT, and PET. The nomogram measuring this prospect may be valuable in skipping intraoperative analysis of SLNs with advantage of reduced operation time and cost.

Abstract
Abstract
Background : Oncotype Dx is being used increasingly for risk stratification to identify for patients with estrogen receptor-positive (ER+), node negative early-stage breast cancer who are most likely to benefit from adjuvant chemotherapy. In Korea, all citizens are covered by national health insurance (NHI), besides patients just pay 5% of hospital bill, if who diagnosed with cancer. NHI can help solve the financial burden for cancer patients.
So the acquisition costs of the Oncotype DX test are sometimes a barrier to its widespread use. This study was conducted for existing cost-effectiveness analyses of Oncotype DX in Korea.
Methods : We analyzed the hospital expenses of patients who diagnosis with LN-negative ER-positive early-stage breast cancer from October 2010 to October 2016 in Seoul National University Hospital. All patients are possible candidates for adjuvant chemotherapy. Among them 273 patients were tested Oncotype Dx. A cost-utility analysis (CUA) was performed.
We analyzed the hospital expenses of chemotherapy by regimens who underwent adjuvant chemotherapy patients, and costs of accompanying adverse event. Each costs of therapy were derived from the hospital administration and expressed by USD. (KRW convert into USD) We also analyzed every patient charges and real expense.
Result :
Of 273 patients, 39(14.3%) were underwent adjuvant chemotherapy. The patients proportion by regimens are FAC(56.4%), AC(10.3%), AC followed by weekly paclitaxel (5.1%), TC(10.3%), AC followed by docetaxel (5.1%), TC and CMF etc. Each patient's hospital expense are roughly 3,000 USD (2,200 – 4,000 USD), it including all costs of laboratory test, computer tomography, chest x-ray, chemoagents and other medications. Of these costs, patients should pay only 5% so it could be around 150 USD (110-200USD).
Disccusion ;
The economic benefits of Oncotype DX are modelled by an overall reduction in chemotherapy usage, thus avoiding associated costs and disutility, and an increase in chemotherapy usage in the high RS group, reducing the risk of recurrence and improving health outcomes. Several studies shows Oncotype DX has been proposed to better estimate baseline risk and response to chemotherapy, to appropriately target chemotherapy to higher risk patients. In the costeffectiveness model, decision making with Oncotype DX in addition to standard decision-making tools is compared with standard decision making without Oncotype DX. From this study, most patient (234 of 273, 85.7%) who are possible candidates for adjuvant chemotherapy avoiding the treatment. A number of studies have looked at the impact of Oncotype DX on clinical decision making. But under the special environment of Korea that most costs who diagnosed with cancer covered by National Insurance health, it relatively expensive than other conturies. So it deserve much consideration that necessity of further studies and reaserches to develop new tools that could be more reasonable in cost in Korea.

Abstract
We conducted a retrospective analysis to evaluate outcomes of haploidentical transplantation in adult severe aplastic anaemia (SAA) patients. Fifty-one adults received haploidentical transplantation between May 2011 and December 2016. Patients were administered busulfan (Bu), cyclophosphamide (Cy) and anti-thymoglobulin (ATG) as conditioning regimens, followed by bone marrow and peripheral blood transplantation. The patients' median age was 25 years. Forty-nine patients survived for more than 28 days and all achieved donor myeloid engraftment. The median time for myeloid engraftment and platelet recovery was 13 days (range, 10-21) and 17.5 (range, 7-101) days. The cumulative incidence (CI) of grade II-IV and III-IV acute GvHD) was 20.00±0.33% and 6.00±0.12%, respectively. The incidence of chronic GvHD was 14.00±0.36% and 25.90±0.71%, and that of moderate-severe chronic GvHD was 2.51±0.06% and 6.92±0.25% at 1 and 3 years, respectively. The 3-year estimated overall survival and failure-free survival were both 83.5±5.4% with a median follow-up of 21.1 months. Multivariate analysis showed hematopoietic cell transplantation-specific comorbidity index (HCT-CI) score of ⩾3 was significantly associated with worse outcome. Haploidentical transplantation conditioning including Bu/Cy/ATG was a safe and effective strategy for adult SAA patients, and HCT-CI might be an outcome predictor in these patients.

Abstract
OBJECTIVES To describe prevalence of osteophytes (OPs) detected only by magnetic resonance imaging (MRI) but not by standard X-ray in older adults and to evaluate longitudinal associations with knee structural changes. METHODS 837 participants were randomly selected from the local community and had MRI scans to assess knee OPs and other structures. OPs detected only by MRI but not by standard X-ray were defined as MRI-detected early OPs (MRI-OPs for short). OPs detected by both MRI and X-ray were defined as established-OPs. RESULTS The prevalence of MRI-OPs was 50% while the prevalence of established-OPs was 10% and no-OPs was 40% at total tibiofemoral (TF) compartment at baseline. Compared with no-OPs, participants with MRI-OPs had greater risks of increased cartilage defects in all TF compartments (RR 1.37, 95%CI 1.07-1.74) and bone marrow lesions (BMLs) only in medial TF compartment (RR 1.49, 95%CI 1.06-2.11), after adjustment for age, sex, BMI, cartilage defects, BMLs and/or joint space narrowing; participants with established-OPs had greater cartilage volume loss at total (β -2.02, 95%CI -3.86, -0.17) and lateral tibial sites (β -5.63, 95%CI -9.93, -1.32), greater risks of increased cartilage defects in total (RR 1.66, 95%CI 1.15-2.40) and medial TF compartments (RR 1.49, 95%CI 1.20-1.69) and BMLs in all TF compartments (RR 1.88, 95%CI 1.22-2.89), after adjustment for covariates. CONCLUSION MRI-OPs were associated with changes in knee structures, and the associations were similar but not as prominent as those for established-OPs. These suggest MRI-OPs may have a role to play in knee early-stage osteoarthritic progression.

Abstract
Objective: To explore a relationship between screening and incidence for colorectal cancer (CRC). Methods: Medline, Scopus, BIOSIS Previews, and the Cochrane Library were searched for studies, which included any randomized controlled trial (RCT) about CRC screening with a report on using endoscopy in screening arms and a usual care in control arms. Results: Nine qualified trials, four one-time and five two-or-more-time screening programs, were included in this review with 997 131 persons randomized and a median follow-up of 10-28 years. In an intention-to-screen analysis, screening was associated with a reduced incidence of advanced CRCs by 10%-60%. Compared with control groups, incidence of CRC firstly increased and then decreased following a screening procedure. Five RCT with six screening arms reported incidences at different follow-up time points, and the incidence ratios at the last time of follow-up were 0.96 (95%CI: 0.86-1.06), 0.80 (95%CI: 0.70-0.92), 1.02 (95%CI: 0.91-1.14), 0.80 (95%CI: 0.70-0.90), 0.83 (95%CI: 0.73-0.94) and 0.94 (95%CI: 0.85-1.05) at the 9.0th, 10.9th, 13.0th, 18.0th, 18.0th, and 19.5th year after baseline, respectively. Compared with population-based screening, people in the hospital/clinic-based screenings had more benefits from CRC incidence reduction, particularly for those with high endoscopy rates, more lesions detected and resected by screening. Conclusions: This study indicates that screening is likely associated with reduction of CRC incidence after 10 years since baseline screening, and this reduction seems to be highly affected by CRC risk of population screened, screening procedure program, and compliance to screening program including accepting endoscopy.

Abstract
Objective: To analyze the clinical value of real-time PCR for virus detection in the diagnosis and treatment of patients after allo-HSCT who had no infection evidence of pneumonia using routine pathogen detection panel. Methods: The clinical data of 71 episodes with acute lung injury from May 2015 to March 2017 after allo-HSCT in hematology department of Peking University People's Hospital (PKUPH) were retrospectively analyzed. PCR for virus detection and other routine pathogen detection tests were performed on bronchoalveolar lavage fluid (BALF) samples. Results: Among 71 episodes with acute lung injury, a total of 15 patients were diagnosed as lower respiratory tract disease merely associated with virus (detection rate of 21.13%) , 19 episodes were absent of lower respiratory tract infection. The median time from allo-HSCT to the occurrence of lung injury were 176 (49-1 376) d and 196 (57-457) d respectively (z=-0.191, P=0.864) . There were no statistical differences for baseline characteristics and clinical features between two groups. The 100-day attributable mortalities were 13.3% (2/15) and 26.3% (5/19) (χ(2)=0.864, P=0.426) . Patients with low-dose steroids treatment had favorable outcome than those with high-dose steroids treatment (the dose of methylprednisolone ≥250 mg/d as standard) [4.2% (1/24) vs 60.0% (6/10) ]. In patients with detectable virus in BALF, 2 patients died with early high-dose steroids treatment, while 11 patients survived with no steroids treatment or late application. Conclusions: Virus infection should be considered in post-HSCT pneumonia patient with negative result using routine pathogen detection panel. Expanding virus detection panel by PCR in BALF could increase diagnostic precision and might be instructive to treatment.

Abstract
Objective: To investigate the prognostic factors of late-onset severe pneumonia (LOSP) in patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: From January 2009 to December 2015, 68 patients with LOSP after allo-HSCT at Peking University Institute of Hematology were enrolled. In this retrospective study, univariate and multivariate analysis were used to evaluate the prognostic factors for LOSP after allo-HSCT. Results: The median time from allo-HSCT to the development of LOSP was 213 (90-2 330) days. The overall survival rate was 42.6% (29/68). The median survival time from LOSP to death was 21 days. Early mortality was defined as death within 21 days after LOSP, as late death more than or equal to 21 days. The median oxygenation index was 199.15 (92.21-290.48) mmHg. LOSPs in thirty-two patients (36.8%) were caused by virus, bacteria, fungi or mixed pathogens. The median C-reactive protein (CRP) was 75.65 (0.94-451.00) mg/L. The median procalcitonin (PCT) was 0.66 (0.00-249.00) μg/L. The higher PCT value indicated an early higher mortality rate by the ROC curve (PCT: cut-off ≥0.94 μg/L). Furthermore, multivariate analysis suggested that PCT more than or equal to 0.94 μg/L was a risk factor for early death of LOSP (OR=5.77, 95%CI 1.66-20.11, P=0.006). LOSP occurred later or equal to 213 days after allo-HSCT was also a risk factor of early death in LOSP (OR=4.74, 95%CI 1.33-16.89, P=0.017). No previous history of chronic graft versus host disease (GVHD) (OR=4.50, 95%CI 1.58-12.83, P=0.005) and LOSP later or equal to 213 days (OR=4.40, 95%CI 1.61-11.99, P=0.004) were the risk factors of late death in LOSP. Conclusions: PCT more than or equal to 0.94 μg/L and LOSP later or equal to 213 days are the risk factors of early death in LOSP. No previous chronic GVHD and LOSP later or equal to 213 days are the risk factors of late death in LOSP.

Abstract
PURPOSE To describe the cross-sectional associations between proximal tibiofibular joint (PTFJ) type configurations and knee joint structural abnormalities in older adults. METHODS A total of 967 community-based participants were studied. T1-weighted fat-suppressed magnetic resonance image (MRI) with spoiled gradient recalled echo sequence was utilized to assess the PTFJ type configurations. Knee cartilage volume, cartilage defects, bone marrow lesions and osteophytes were measured. Linear regression and binary logistic regression analyses were used to examine the associations between PTFJ type configurations and knee joint cartilage volume as well as knee structural abnormalities, respectively, after adjustment for potential confounders. RESULTS Seven PTFJ types including plane (49.4%), trochoid (31.9%), double trochoid (4.3%), saddle (5.4%), condylar (5.3%), trochlear (3.5%) and ball & socket (0.2%) were observed. Plane type was used as the comparator. In multivariable analyses, irregular joint types (comprising the five uncommon joint types) were associated negatively with cartilage volume, and positively with knee cartilage defects, bone marrow lesions and osteophytes in the lateral (but not medial) compartments. In contrast, trochoid type was only associated with reduced femoral cartilage volume, but not with knee cartilage defects, bone marrow lesions and osteophytes. CONCLUSIONS Irregular PTFJ joint shapes are associated with osteoarthritic changes in the lateral, but not medial, tibiofemoral compartment in older adults. The causal relationship needs to be examined in future longitudinal studies.

Abstract
The objective of the study is to analyze the biological characteristics and stability of the linear derivative Bac2a from bactenecin, compared with the control peptide melittin. The secondary structure, antibacterial activity, hemolytic activity, cell toxicity and stability of the Bac2a were determined by circular dichroism spectroscopy, broth micro-dilution method and MTT assay. The results showed that Bac2a was a nonregular curl in aqueous solution, however, it was an α-helix structure in the hydrophobic environment. The minimal inhibitory concentration (MIC) of Bac2a ranged from 2 to 32 μmol/L, so the bacteriostatic activity of Bac2a was strong. The hemolytic rate was only 14.81% when the concentration of Bac2a was 64 μmol/L, which showed that the hemolytic rate of Bac2a was low. The therapy index of Bac2a was 3.26, and the cytotoxicity was relatively low, thus the cell selectivity was relatively high. In addition, with the heating treatment of 100℃ for 1 h, Bac2a still possessed rather a high antibacterial activity and showed a good heating stability. In a word, Bac2a has good application prospects in food, medicine and other fields, and is expected as a substitute for traditional antibiotics.

Abstract
Objective: To compare incidence and clinical features of hemorrhage cystitis (HC) after haploidentical donor (HID) allogeneic hematopoietic stem cell transplantation (HSCT) and matched sibling donor (MSD) HSCT. Methods: Medical records of 609 (including 406 HID-HSCT and 203 MSD-HSCT cases) hematologic malignancies patients treated with HSCT undergoing myeloablative conditioning regimen from January 2011 to December 2012 were analyzed retrospectively. Results: HC occurred 183 in HID and 17 ones in MSD respectively. The cumulative incidence of HC in HID group was higher than in MSD group[ (45.6±2.5) % vs (8.5±2.0) %, χ(2)=77.331, P<0.001], and the cumulative incidence of severe HC (grade 3-4) in HID cases was also higher than in MSD ones[ (11.2±1.9) % vs (2.1±1.1) %, χ(2)=12.883, P<0.001]. All HCs were occurred within 180 days in both groups. The median time to onset in two groups were 27 days after HSCT (range 0-177 days) and 29 days after HSCT (range 6-72 days) respectively (P=0.766) . The median duration of HC in two groups were 21 days (range 3-157 days) and 13 days (range 5-67 days) , respectively (P=0.182) . The total efficiency of treatment in two groups were 69.9% and 70.6% respectively (χ(2)=0.003, P=1.000) . Conclusion: The cumulative incidences of HC and severe HC were higher in HID cases than in MSD ones. The median time to onset and median duration of HC and therapeutic outcome between HID and MSD were comparable.

Abstract
OBJECTIVE To develop a measure of knee joint effusion-synovitis volume and to examine the effect of vitamin D supplementation on effusion-synovitis in people with knee osteoarthritis (OA) and low vitamin D levels over 24 months. METHOD Symptomatic knee OA patients with low 25-(OH)D levels (12.5-60 nmol/l) were recruited for a multi-centre, randomised, placebo-controlled and double-blind trial. Participants (age 63 ± 7 years, 208 females) were allocated to either 50,000 IU monthly vitamin D3 (n = 209) or placebo (n = 204) for 24 months. Knee effusion-synovitis volume in suprapatellar and other regions was measured on magnetic resonance imaging (MRI) using OsiriX software. The intra-class correlation coefficients (ICCs) were used to test inter- and intra-rater reliabilities. The least significant change criterion was used to define the increase/decrease in effusion-synovitis volume. RESULT The reproducibilities of effusion-synovitis volume measurement were high with ICCs ranging from 0.93 to 0.99. Over 24 months, effusion-synovitis volume remained stable in the vitamin D group but increased in placebos with a significant between-group difference (-1.94 ml, 95% confidence interval (CI): -3.54, -0.33). This effect was evident in those with baseline effusion-synovitis and with suprapatellar effusion-synovitis. The proportion with an increase in effusion-synovitis volume was lower in the vitamin D group than placebo (risk ratio (RR): 0.87, 95% CI: 0.77, 0.97). CONCLUSION This highly reproducible effusion-synovitis volume measurement could be a promising outcome measure in OA trials. Vitamin D supplementation could retard the progression of effusion-synovitis which can potentially benefit people with an inflammatory OA phenotype.

Abstract
OBJECTIVE To investigate the longitudinal association between endogenous sex hormones and knee osteoarthritis (OA) structures and pain. METHOD We examined 200 participants (mean age 63.0 ± 7.3 years) from a clinical trial of vitamin D supplement for symptomatic knee OA. Serum levels of estradiol, progesterone, testosterone and sex hormone binding globulin (SHBG) were analyzed at baseline and 24 months later. Magnetic resonance imaging (MRI) scans of selected knee were obtained at both baseline and follow-up for the measurement of cartilage volume, cartilage defects, bone marrow lesions (BMLs) and effusion-synovitis volume. Knee pain was assessed using a 100 mm visual analogue scale (VAS). Longitudinal data were analyzed using linear mixed-effects model. RESULTS One hundred and seven males and 93 females were included in this study. For females, after adjustment for age, body mass index (BMI), and vitamin D level, progesterone was positively associated with cartilage volume (β = 0.12 mm3 per quartile, P < 0.01). Estradiol levels were associated with lower grades of BMLs (β = -0.46 per quartile, P = 0.03), while estradiol (β = -1.28 per quartile, P = 0.04), progesterone (β = -1.56 per quartile, P < 0.01) and testosterone (β = -1.51 per quartile, P = 0.01) were inversely associated with effusion-synovitis volume. Testosterone was inversely associated with knee pain. No consistent associations were observed for males. CONCLUSION In women but not men, low serum levels of endogenous estradiol, progesterone and testosterone are associated with increased knee effusion-synovitis and possibly other OA-related structural changes. This may contribute to observed sex differences in knee OA.

Abstract
OBJECTIVE To describe cross-sectional and longitudinal associations between magnetic resonance imaging (MRI)-detected osteophytes (OPs) and knee structural abnormalities and knee pain in older adults. METHOD A prospective population-based cohort study of 895 participants aged 50-80 years (mean age 62 years, 50% female) was performed. T1-or T2-weighted fat suppressed MRI was used to assess knee OPs, cartilage volume, cartilage defects and bone marrow lesions (BMLs) at baseline and after 2.6 years. Radiographically-detected OPs were scored according to the Osteoarthritis Research Society International (OARSI) atlas. Knee pain was assessed using a self-administered questionnaire at baseline, 2.6 and 5 years later. RESULTS 85% of participants had MRI-detected OPs at baseline, while 10% of participants had radiographically-detected OPs. Cross-sectionally, higher gardes of MRI-detected OPs in all compartments were significantly, independently and site-specifically associated with higher prevalences of cartilage defects and BMLs, lower cartilage volume and higher prevalence of knee pain. Longitudinally, higher gardes of baseline MRI-detected OPs site-specifically predicted greater risks of any increase in cartilage defects or BMLs, and loss of cartilage volume in medial and lateral tibiofemoral (LTF) and total compartments over 2.6 years in multivariable analyses. These significant associations were similar in those without radiographically-detected OPs. MTF and total OP scores were significantly associated with change in total knee pain over 2.6 and 5 years but these became non-significant after adjustment for cartilage defects and BMLs. CONCLUSION MRI-detected knee OPs are common and appear to be clinically relevant to knee structural changes in older adults.

Abstract
OBJECTIVE To evaluate the security and efficiency of a surgical robotic assisted percutaneous screw fixation for the treatment of pelvic and acetabular fractures. METHODS In the study, 12 patients with pelvic and acetabular fractures who were treated in Beijing Jishuitan Hospital from January to April in 2016 were involved in this research. The research subjects were randomly divided into two groups: the experimental group and the control group. Robotic-assisted percutaneous sacroiliac screw internal fixations were performed under the guidance of fluoroscopy navigation in the experimental group; in the control group, doctors operated manually guided by fluoroscopy. Statistical analysis was performed on the total operation time, the intraoperative fluoroscopy time, the adjustment numbers of intraoperative guide wires, the excellent rate of screw placement and the incidence of adverse events in order to evaluate the security and efficiency of a surgical robotic assisted percutaneous screw fixation for the treatment of pelvic and acetabular fractures. RESULTS Eleven screws were placed in 7 patients from the experimental group, while 7 screws were placed in 5 patients from the control group in total. All the screw placement positions were satisfactory according to postoperative CT images. The excellent rates of screw placement position were 100% in both groups. However, the P value was 0.016 based on the comparison between the screws' distribution in the two groups which meant that the screw distribution of the experimental group was better than that of the control group. The average fluoroscopy time needed for screw insertion was (7.36±2.63) s in the experimental group while (41.80±13.99) s in the control group (P<0.001). This suggested that the difference between the two groups had statistical significances. Intra-operative fluoroscopy time of the experimental group was significantly smaller than that of the control group. The number of the average screw adjustment was (0.36±0.48) times in the experimental group while (9.00±3.06) times in the control group (P=0.003). This suggested that the difference of the number of the guide needle adjustment between the two groups had statistical significances, and the number of the experimental group was smaller than that of the control group. The average operation time was (43.86±49.06) min in the experimental group while only (29.00±12.14) min were needed in the control group (P=0.528). This suggested that the difference between the two groups had no statistical significance. That is, the total operation time of the two groups was equal. All the screws were in satisfactory positions according to validation results of CT scans. No complications such as screw breaking out the bone cortex and entering into the knee joint cavity, wound infection occurred. CONCLUSION Surgical robots are suitable for robot-assisted percutaneous screw fixation in pelvic and acetabular fractures. Robot-assisted treatment of pelvic and acetabular fractures has significant advantages over manual operations including high accuracy, small perspective radiation, safety and efficiency.

Abstract
OBJECTIVE To describe cross-sectional and longitudinal associations between serum levels of interleukin (IL) - 6, IL-17A, IL-17F, IL-23 and knee bone marrow lesions (BMLs) in patients with knee osteoarthritis (OA). DESIGN Patients (n = 192) with symptomatic knee OA (mean 63 years, range 50-79, female 53%) were assessed at baseline and after 24 months. At each time point, serum IL-6, IL-17A, IL-17F and IL-23 were measured using Bio-Plex® Multiplex Immunoassays with Luminex xMAP technology. Knee BMLs were scored using the modified whole organ MRI score (WORMS) from T2 weighted fat-suppressed fast spin echo magnetic resonance imaging (MRI). Multivariable linear regression and log binominal regression were used to determine the associations between cytokines and BMLs. RESULTS Baseline IL-6 (quarters) were significantly associated with total knee BMLs (P < 0.01 for the trend) as well as associated with an increase in BML score (P = 0.05 for the trend), after adjustment for confounders. Baseline IL-17F and IL-23 (highest quarters vs others) was associated with an increase in BML score in females (P = 0.04 for IL-17F; P = 0.01 for IL-23), but not in males, in multivariable analyses. In contrast, IL-17A was not significantly associated with BMLs in either females or males. CONCLUSION IL-6 is associated with increased knee BMLs in both females and males with OA. Serum IL-17F and IL-23 predicted increased knee BML scores in females only, suggesting that inflammation is involved in BML pathogenesis in knee OA, especially in women.

Abstract
Abstract
Purpose
We aimed to identify whether hormonal receptors change throughout tumor progression, because this may influence management and influence prognosis in breast cancer patients.
Patients and Methods
From the institution's database, we collected data of 963 patients who developed relapse during their follow-ups. To determine estrogen receptor(ER) and progesterone receptor (PR), we retrospectively reviewed immunohistochemical(IHC) results in both primary and relapsed tumors.
Results
Among a total of 963 patients, 280 and 683 patients experienced locoregional relapse only and distant metastasis irrespective of locoreginal relapse, respectively. ER in 650 patients and PR in 590 patients from both primary tumor and relapse were identified, revealing a change in 157 (24.2%) and 154 (26.1%) patients, respectively. In patients with distant metastasis, assessment of ER and PR showed an alteration in 86 and 56 patients, respectively. The overall survival related to the change of ER and PR status in primary tumor and relapse was significantly different (log rank, P<0.001 in both ER and PR status). In addition, women with hormone receptors negative primary tumors that changed to hormone receptors positive tumors who received anti-hormonal therapy after relapse showed a statistically significant good overall survival (p<0.001) compared with women who had constant ER-negative tumors.(cox regression, hazard ratio 2.32 ; 95% CI, 1.91 to 3.01)
Conclusion
The breast cancer showed alterations of hormone receptor status throughout tumor progression, hat were related to the strategy of treatment and significantly influences survival. Therefore, investigations of hormone receptor at relapse are essential and helpful in breast cancer patient management.

Abstract
Abstract
Background: The management of benign intraductal papillomas on core biopsy is controversial. The aim of this study was to determine factors that predict under-evaluation of atypical lesion or malignancy in patients diagnosed with benign papilloma at ultrasound-guided core needle biopsy (CNB), and to develop a prediction algorithm for scoring the possibility of a diagnosis upgrade to atypical lesion or malignancy based on clinical, radiological and pathological factors.
Methods: The study enrolled patients diagnosed with benign papilloma at ultrasound-guided CNB who subsequently underwent surgical excision of the lesion. Multivariate analysis was used to identify relevant clinical, radiological and pathological factors that may predict malignancy.
Results: A total of 520 CNBs led to a diagnosis of benign papilloma (including benign and atypical papillary lesion), of which 452 CNBs were benign papilloma without atypia. Of the 250 lesions in 234 women were underwent subsequent surgical excision, 44 (17.6%) were diagnosed with atypia or malignancy. Multivariate analysis revealed that bloody nipple discharge, size on imaging ≥15 mm, BIRADS≥4b, peripheral location, and a palpable lesion were independent predictors of atypical lesion or malignancy. A scoring system was developed based on logistic regression models and beta coefficients for each variable. The area under the ROC curve was 0.830 (95% CI: 0.665-0.996), and the negative predictive value was 100% for a score ≤4.
Conclusions: A scoring system to predict malignancy in patients diagnosed with benign papilloma at CNB was developed based on five factors: bloody nipple discharge, size on imaging ≥15 mm, BIRADS≥4b, peripheral location, and a palpable lesion. This system was able to identify a subset of patients with lesions likely to be benign, indicating that imaging follow-up rather than surgical excision may be appropriate.

Abstract
Regeneration of damaged neurons and recovery of sensation and motor function after complete spinal cord injury (SCI) are challenging. We previously developed a collagen scaffold, NeuroRegen, to promote axonal growth along collagen fibers and inhibit glial scar formation after SCI. When functionalized with multiple biomolecules, this scaffold promoted neurological regeneration and functional recovery in animals with SCI. In this study, eight patients with chronic complete SCI were enrolled to examine the safety and efficacy of implanting NeuroRegen scaffold with human umbilical cord mesenchymal stem cells (hUCB-MSCs). Using intraoperative neurophysiological monitoring, we identified and surgically resected scar tissues to eliminate the inhibitory effect of glial scarring on nerve regeneration. We then implanted NeuroRegen scaffold loaded with hUCB-MSCs into the resection sites. No adverse events (infection, fever, headache, allergic reaction, shock, perioperative complications, aggravation of neurological status, or cancer) were observed during 1 year of follow-up. Primary efficacy outcomes, including expansion of sensation level and motor-evoked potential (MEP)-responsive area, increased finger activity, enhanced trunk stability, defecation sensation, and autonomic neural function recovery, were observed in some patients. Our findings suggest that combined application of NeuroRegen scaffold and hUCB-MSCs is safe and feasible for clinical therapy in patients with chronic SCI. Our study suggests that construction of a regenerative microenvironment using a scaffold-based strategy may be a possible future approach to SCI repair.

Abstract
Abstract
Background
Although the surgical safety checklist (SSC) has been adopted worldwide, its efficacy can be diminished by poor clinical motivation. Systematic methods for improving implementation are lacking.
Methods
A multicentre prospective study was conducted in 2015 in four academic/teaching hospitals to investigate changes during revision of the SSC for content, staffing and workflow. All modifications were based on feedback from medical staff. Questionnaires were used to monitor dynamic changes in surgeons', nurses' and anaesthetists' perceptions.
Results
Complete information was obtained from 30 654 operations in which the newly developed SSC system was used. Implementation quality was evaluated in 1852 operations before, and 1822 after the changes. The revised SSC content was simplified from 34 to 22 items. Anaesthetists achieved widespread recommendation as SSC coordinators. Completion rates of all stages reached over 80·0 per cent at all sites (compared with 10·2–59·5 per cent at the sign-out stage in the baseline survey). There was a significant change in doctors who participated (for example, surgeon: from 24·6 to 64·5 per cent at one site). The rates of hasty (15·1–33·7 per cent) or casual (0·4–4·4 per cent) checking decreased to less than 6·0 per cent overall. Perceptions about the SSC were studied from 2211 forms. They improved, with a converging trend among the three different professions, to a uniform 80·0 per cent agreeing on the need for its regular use.
Conclusion
Medical staff members are both the users and owners of the SSC. High-quality SSC implementation can be achieved by clinically motivated adaptation.

Abstract
To explore the effect of SOX2 on osteogenic differentiation of dental pulp stem cells (DPSCs) and to develop a new method for facilitating osteogenic differentiation of DPSCs. SOX2-overexpressing human DPSCs (DPSCs-SOX2) were established through retrovirus infection. Differentiation was induced with osteogenic differentiation medium and further evaluated by alkaline phosphatase (ALP) staining and qPCR. Following the differentiation procedure, the mechanism of SOX2 on osteogenic differentiation of DPSCs was analyzed using genome RNA microarray and flow cytometry. The normal DPSCs, DPSCs-vector, and DPSCs-SOX2 were capable of osteogenic differentiation after 3-4 weeks of introduction and positive for ALP staining. Compared to DPSCs and DPSCs-vector, DPSCs-SOX2 exhibited higher levels of osteogenic gene expression (ALP, collagen I, Runx2, and osterix), indicating the superiority of DPSCs-SOX2 in osteogenic differentiation. Moreover, SOX2 overexpression resulted in the activation of the Hippo signal pathway and increased expressions of the BMPs family. SOX2 promotes the osteogenic differentiation of DPSCs by regulating the osteogenic genes and BMPs family, suggesting the therapeutic potential in bone repair.

Abstract
A compact neutron spectrometer, based on a CH foil for the production of recoil protons and CR-39 detection, is being developed for the measurements of the DD-neutron spectrum at the NIF, OMEGA, and Z facilities. As a CR-39 detector will be used in the spectrometer, the principal sources of background are neutron-induced tracks and intrinsic tracks (defects in the CR-39). To reject the background to the required level for measurements of the down-scattered and primary DD-neutron components in the spectrum, the Coincidence Counting Technique (CCT) must be applied to the data. Using a piece of CR-39 exposed to 2.5-MeV protons at the MIT HEDP accelerator facility and DD-neutrons at Z, a significant improvement of a DD-neutron signal-to-background level has been demonstrated for the first time using the CCT. These results are in excellent agreement with previous work applied to DT neutrons.

Abstract
PURPOSE To assess reliability and validity of a semi-automated quantitative method to measure infrapatellar fat pad (IPFP) signal intensity in patients with knee osteoarthritis (OA). METHODS Hundred patients with knee OA were selected. Sagittal planes of fat-saturated T2-weighted images obtained on 1.5-T magnetic resonance imaging (MRI) were utilized to assess IPFP signal intensity using MATLAB. Knee structural abnormalities including cartilage defects, bone marrow lesions (BML) and radiographic OA (ROA) were evaluated. Clinical construct validity and concurrent validity were examined through describing associations of IPFP measurements with knee structural abnormalities and a semi-quantitative scoring method, respectively. The reliability was examined by calculating the intra- and inter-observer correlation coefficients. RESULTS Significantly positive associations were found between standard deviation of IPFP signal intensity [sDev (IPFP)], clustering factor (H) and all knee structural abnormalities. The volume of high signal intensity regions [Volume (H)] and the ratio of Volume (H) to volume of whole IPFP [Percentage (H)] were positively associated with cartilage defects and ROA, but not with BMLs. The median value [Median (H)] and upper quartile value [UQ (H)] of high signal intensity were only significantly associated with quartiles of cartilage defect score. Significant correlations were found between all quantitative measurements and semi-quantitative scores (All P < 0.001). Intraclass and interclass correlation coefficients for these quantitative measures were high (>0.90). CONCLUSIONS A novel and efficient method to segment IPFP and calculate its signal intensity on T2-weighted MRI images is documented. This method is reproducible, and has concurrent and clinical construct validity, but its predictive validity needs to be examined by future longitudinal studies.

Abstract
We investigated the impact of donor type on post-relapse survival (PRS) in 85 patients with hematological relapse after their first allogeneic hematological stem cell transplantation (allo-HSCT) for hematological malignancy. The median follow-up was 64 months among survivors. Both 3-year overall survival and 3-year PRS were similar in haploidentical donor (HID) and matched sibling donor (MRD) transplantation (13.0%±4.7% vs 19.4%±7.1%, P=0.913 and 7.7±3.9% vs 9.7±5.3%, P= 0.667). Higher rates of post-relapse grade II-IV and III-IV acute GvHD (aGvHD) were observed in HID transplantation patients. A higher cumulative incidence of post-relapse extensive chronic GvHD was also observed for HID transplantation patients. Multivariate analyses confirmed that treatment including donor lymphocyte infusion (DLI), late relapse >1 year, and in first CR at transplantation were associated with superior PRS (P=0.012, hazard ratio (HR)=0.527 (0.320-0.866)); P=0.033, HR=0.534 (0.300-0.952) and P=0.046, HR=0.630 (0.400-0.992). The data suggest that post-relapse outcomes are comparable in HID and MRD transplantation, and that DLI is safe for relapsed patients after haploidentical transplantation.

Abstract
OBJECTIVE To study the efficacy and safety of radiofrequency catheter ablation (RFCA) in patients with different forms of atrial fibrillation. PATIENTS AND METHODS By retrospective analysis, we summarize 720 cases, where patients diagnosed with atrial fibrillation in our hospital were treated with RFCA from February 2010 to October 2014. Among the cases, 425 were diagnosed with paroxysmal atrial fibrillation and 295 with non-paroxysmal atrial fibrillation (including persistent atrial fibrillation and permanent atrial fibrillation). All patients were followed up until June 2015 to compare and analyze the differences in operation success rates, complications and recurrence rates. RESULTS 395 cases (92.9%) of paroxysmal atrial fibrillation and 253 cases (85.8%) with non-paroxysmal atrial fibrillation were subject to surgery and followed up. The age of onset, disease course, underlying diseases, left atrial diameter and combined anti-arrhythmics of patients with paroxysmal atrial fibrillation were lower than those of patients with non-paroxysmal atrial fibrillation, and the differences were statistically significant (p < 0.05). The success rate of the first ablation was higher than that of non-paroxysmal atrial fibrillation. Procedure time, procedure method, complications and recurrence rate of patients with paroxysmal atrial fibrillation were lower than those of non-paroxysmal atrial fibrillation group, and the differences were statistically significant (p < 0.05). When we compared apoplexy and heart failure caused by atrial fibrillation in the two groups, the difference was not statistically significant (Apoplexy: p = 0.186; Heart failure: p = 0.170). CONCLUSIONS The individual ablation success rate was higher for paroxysmal atrial fibrillation, and long-term follow-up showed that the occurrence of apoplexy and heart failure was not different from the non-paroxysmal atrial fibrillation group.

Abstract
Background In this study, we aimed to evaluate the prognostic factors associated with and treatments for late‐onset severe pneumonia (LOSP) in patients who underwent allogeneic hematopoietic stem cell transplantation (allo‐HSCT). Methods Fifty consecutive patients who underwent non‐T‐cell‐depleted allo‐HSCT at the Peking University Institute of Hematology and met the criterion of LOSP after allo‐HSCT were enrolled. Results The median time from allo‐HSCT to the occurrence of LOSP was 231 (90–1487) days. Twenty‐eight patients harbored 1 or more pathogens (infectious LOSP, I‐LOSP), whereas 22 did not harbor any pathogens (non‐infectious LOSP, NI‐LOSP). The 100‐day survival rate of LOSP patients was 31.1%. Patients smoking before allo‐HSCT (0% vs. 35.4%, P = 0.002) and male gender (20.0% vs. 61.9%, P = 0.026) had lower 100‐day survival rate. Patients with a lower bronchoalveolar lavage fluid (BALF) neutrophil percentage had higher 100‐day survival rate relative to those with higher BALF neutrophil percentage (45.5% vs. 16.7%, P = 0.012). The 100‐day survival rate of patients with I‐LOSP was lower than that of patients with NI‐LOSP (19.1% vs. 46.9%, P = 0.043). Patients given late (≥1 week after LOSP diagnosis) and low‐dose methylprednisolone (MP) therapy (≤2 mg/kg/day) had the best 100‐day survival rate. In the multivariate analysis, nonsmoking before allo‐HSCT and late and low‐dose MP therapy were significantly associated with a better survival after LOSP. Conclusion LOSP is a severe complication after allo‐HSCT. The correct timing and corticosteroid dosage in the context of broad‐spectrum antimicrobial therapy might further improve the outcomes of patients with LOSP.

Abstract
A reliable analytical method based on liquid chromatography-tandem mass spectrometry was developed for simultaneous determination of aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1, aflatoxin G2, ochratoxin A (OTA), deoxynivalenol, T-2 and HT-2 toxin, and zearalenone (ZEA) in various dried fruits. A simple one-step sample extraction without using clean-up cartridges made the established method less labour consuming and less expensive, while optimisation of the several important MS/MS parameters, i.e. the scan time and run segments, ensured its sensitivity and selectivity. After careful validation of the method by determining the linearity (R2>0.99), recovery (77.8-115.9%), precision (relative standard deviation ≤19.5%) and sensitivity (limits of quantification in the range of 0.1-10 μg/kg), a survey of 125 dried fruit samples including 25 pistachios, 28 dried longans, 32 raisins and 40 dried dates randomly collected from different markets in Shanghai, China, was performed. Results revealed that 32.0% of samples were contaminated with different mycotoxins, among which, OTA was the most frequent contaminant with the incidence of 29.6% attaining the concentration levels in the range of 0.4-212.6 μg/kg. ZEA was positively found in 2 pistachio samples with the concentrations of 84.9 μg/kg and 426.9 μg/kg. Trace amounts of AFB1 (0.8 μg/kg) and AFB2 (0.2 μg/kg) were also observed in one pistachio sample and one dried longan sample, respectively. To the best of our knowledge, this is the first report to reveal the real situations of mycotoxin contaminations in various dried fruits in China.

Abstract
Mannan derived from fungal cell walls have potential uses as immunomodulating agents and vaccine adjuvants. Immunization with antigen conjugated to oxidized mannan (OM) or reduced mannan (RM) have induced differential immune responses in mice. Yet, the adjuvant effect and differences in molecular profiles of OM and RM on APCs is unresolved. Here, we investigated the response of mouse bone marrow-derived DCs to OM and RM. OM and RM stimulated DCs to produce differential Th1/Th2-inducing cytokines in vitro. OM and RM-activated DCs stimulated allogeneic T-cell Th1 and Th2 polarization reaction. OM instruct DCs to stimulate Th1 responses via IL-12p70 production, which depends on the phosphorylation of p38, RM barely induce IL-12p70, but IL-10 and IL-4, and magnitude of ERK phosphorylation, which results in a Th2 bias. These findings indicate that OM and RM were potent adjuvant capable of directly initiating DC activation Th1 and Th2 polarization respectively.
