Objective To investigate the clinical efficacy and prognostic factors of breast cancer patients with ipsilateral supraclavicular lymph node metastasis (ISLNM) receiving neoadjuvant chemotherapy,surgery combined with radiotherapy at diagnosis.Methods Therapeutic outcomes of 65 breast cancer patients with ISLNM treated in our hospital between 1999 and 2013 were retrospectively analyzed.All patients were pathologically diagnosed with breast cancer.They were complicated with ISLNM,without distant metastasis confirmed by pathological or imaging examinations.All patients received multi-modality therapy consisting of neoadjuvant chemotherapy,surgery and postoperative radiotherapy.KaplanMeier method was adopted to calculate the overall survival (OS),progression-free survival (PFS) and supraclavicular lymph node recurrence (SCFR).The differences between two groups were statistically analyzed by the log-rank test.Results The median follow-up time was 66 months (range:6-137 months).Five patients had SCFR after corresponding treatment.The overall 5-year SCFR,OS and PFS rates were 9.2％,71.5％ and 49.5％,respectively.Following preoperative chemotherapy,the complete response (CR) of supraclavicular lymph node was a prognostic factor affecting OS.The 5-year OS rates in patients with and without CR were 81.4％ and 53.9％ (P=O.035).The size of supraclavicular lymph node (≤ 1 cm vs.＞ 1 cm at diagnosis was a risk factor of the SCFR (0％ vs.21.0％,P=0.037) and OS rates (≤1 cm vs.＞1 cm:86.1％ vs.55.6％,P =0.001).Conclusions Breast cancer patients with ISLM at diagnosis can obtain high OS rate and excellent tumor control after undergoing multi-modality therapy consisting of preoperative chemotherapy,surgery and postoperative radiotherapy.

Objective To analyze the changes in treatment patterns,clinical characteristics,treatment outcomes and prognostic factors of ductal carcinoma in situ (DCIS).Methods Clinical data of 617 female patients admitted to our institution between 2000 and 2013 were retrospectively analyzed.KaplanMeier survival analysis was adopted to calculate the local control (LC),disease-free survival (DFS) and overall survival (OS) rates.Log-rank test was utilized to identify the prognostic factors.Results Along the number of DCIS patients was gradually increased year by year,the proportion of breast conservative surgery was also elevated.However,mastectomy remained the primary surgical method.A total of 374 patients underwent mastectomy,160 cases received breast conservative surgery plus radiotherapy and 83 underwent breast conservative surgery alone.Postoperatively,366 patients (83.6％) with positive hormone receptor received hormone therapy and 45 patients (7.3％) underwent chemotherapy.The median follow-up time was 47 months.The 5-year LC,DFS and OS rates were 98.4％,97.5％ and 98.9％,respectively.Univariate analysis demonstrated that Her-2-positive patients obtained worse OS (P=0.019).Although mastectomy group had more adverse factors compared with breast conservative surgery with or without radiotherapy groups,similar survival results were obtained among three groups.Mastectomy yielded better LC and DFS compared with breast conservative surgery alone.Conclusions DCIS patients obtain favorable clinical prognosis between the breast conservative surgery and mastectomy groups.The LC rate in the mastectomy group is better than that in the breast conservative surgery group.

Objective To evaluate the risk factors of non-sentinel lymph node (NSLN) metastasis in breast cancer patients with 1-2 positive sentinel lymph nodes and to establish a new Nomogram prediction model.Methods Clinicopathological data of breast cancer patients who were diagnosed with 1-2 positive lymph nodes and underwent axillary lymph node dissection (ALND) without neoadjuvant chemotherapy from January 2008 to December 2014 were retrospectively analyzed.Measurement data between two groups were analyzed by chi-square test.Multivariate analysis was performed by logistic regression model.The prediction accuracy of the Nomogram model was evaluated using the area under the receiver operating characteristic curve (AUC) and calibration curves.Results A total of 270 patients were recruited in this study.Among them,87(32.2％) patients had NSLN metastases.The median age was 46 years old (21-80 years),the median number of SLNs was 4 (1-10) and the median number of axillary lymph nodes was 20(10-41).Univariate analysis demonstrated that the pathological grade,the size of SLN metastasis,the number of negative and positive SLNs were the risk factors of NSLN metastasis (P=0.001-0.045).Multivariate analysis showed that pathological grade,the number of negative and positive SLNs were independent risk factors of NSLN metastasis (P=0.000-0.041).The AUC value of Nomogram prediction model for NSLN metastasis was 0.70.The false negative rate of Nomogram was 10.5％ when the cut-off point of predictive probability was ≤ 15％.Conclusions The Nomogram is a useful prediction model for evaluating NSLN metastasis.ALND or axillary radiotherapy can be avoided for patients with a low probability of NSLN metastasis.

Objective To investigate the value of 68Ga-prostate specific membrane antigen (PSMA)-617 PET/CT in predicting high-risk prostate cancer.Methods From May 2016 to January 2017,30 patients (median age 67 years) with biopsy-proven prostate cancer were included.The 68Ga-PSMA-617 PET/CT images and clinical data of all patients were analyzed retrospectively.According to prostate cancer risk stratification criteria of National Comprehensive Cancer Network (NCCN) Guidelines (including Gleason scores,prostate specific antigen (PSA)),all patients were classified into low-moderate-risk group and high-riak group.PET images were analyzed semi-quantitatively and maximum standardized uptake value (SUVmax) of primary prostate cancer was measured.SUVmax of 68Ga-PSMA-617 PET/CT was used to establish logistic regression model for predicting high-risk prostate cancer,and the diagnostic efficiency of the model was evaluated by receiver operating characteristic (ROC) curve analysis.Results The median Gleason score of 30 patients was 7.5 (7,9),and the median PSA was 34.0 (19.4,119.1) μg/L,including 9 patients with PSA≤ 20 μg/L and 21 patients with PSA＞20 μg/L.According to the NCCN Guidelines,there were 24 patients with high-risk prostate cancer and 6 patients with low-moderate-risk prostate cancer.SUVmax was higher in high-risk group than that in low-moderate-risk group (14.2 (11.4,23.1) vs 7.9 (3.8,13.1);u =118,P＜ 0.05).Logistic regression model established with SUVmax could effectively predict high-risk prostate cancer with the area under ROC curve of 0.819.When the cut-off value was set as 0.73,the sensitivity and specificity of the model were 87.5％(21/24) and 4/6 respectively.Conclusion SUVmax of 68Ga-PSMA-617 PET/CT can be used as an imaging biomarker for predicting high-risk prostate cancer.

Objective To prepare human epidermal extracts by thermal separation,and to evaluate the value of epidermal extract-based Western blot analysis in the diagnosis of bullous pemphigoid (BP).Methods Human epidermal extracts were prepared by thermal separation from circumcised foreskins of healthy males.Serum samples were obtained from 22 inpatients with BP and 25 inpatients without BP in Hospital for Skin Diseases,Chinese Academy of Medical Sciences and Peking Union Medical College between January 2015 and August 2017.These serum samples were subjected to Western blot analysis with epidermal extracts as substrates,as well as to BP180-NC16A enzyme-linked immunosorbent assay (ELISA).Statistical analysis was carried out using chi-square test and Fisher's exact test with the SPSS22.0 software.Results The sensitivities of epidermal extract-based Western blot analysis and BP 180-NC16A ELISA in the diagnosis of BP were 86.36％ (95 ％ CI:64.03％-96.41％) and 95.45％ (95％ CI:75.11％-99.76％) respectively (~ =1.10,P =0.294),and the specificities were 100％ (95％ CI:83.42％-100％) and 92％ (95％ CI:75.11％-99.76％) respectively (x2 =20.8,P =0.149).Epidermal extract-based Western blot analysis in the 22 patients with BP showed a protein band with relative molecular mass (RMM) of 230 000 in 4 patients,a protein band with RMM of 180 000 in 18,a protein band with RMM of 120 000 in 1,and a protein band with RMM of 97 000 in 1.The BP180-NC16A ELISA showed that the antibody titers were more than 50 U/ml in the BP patients with protein bands of RMM of 180 000.Conclusions The epidermal extract-based Western blot analysis mainly showed the protein band with RMM of 180 000 in the patients with BP.The sensitivity of the epidermal extract-based Western blot analysis was lower than that of the BP180-NC16A ELISA,and the epidermal extract-based Western blot analysis tends to be negative when the titer of the autoantibody is low.

Objective To explore the clinicopathological characteristics,diagnosis,treatment and prognosis of accessory breast cancer.Methods Clinical and pathological data of 37 accessory breast cancer patients from Dec 2005 to Aug 2017 were reviewed.Results 12 patients underwent breast-conserving local wide excision plus axillary lymph node dissection.5 cases were treated by segmental resection and 19 patients by Auchincloss or Halsted mastectomy;One patient abandoned surgery.The most common histological type of accessory breast cancer was infiltrating ductal carcinoma (26 cases,70.3％) followed by adenocarcinoma (4 cases) and miscellaneous type (7 cases).The most common AJCC pathological stages were stage Ⅱ (n =24,65 ％),Ⅰ (n =8),Ⅲ(n =3) and Ⅳ (n =2).The median follow-up time was 6 (1-12) years,the followup rate was 100％.Until Dec 2017,7 patients died from metastasis and the others were alive.Conclusions Accessory breast cancer is rare and with poor prognosis.The diagnosis depends on clinical manifestations,imaging and pathology.Surgery is the mainstay therapy,adjuvant chemo therapy is recommanded.

Objective To analyze the role of lienal polypeptide injection in acute lung injury induced by lipopolysaccharide (LPS) in rats. Methods Eighty male SD rats were randomly allocated into 4 groups: a LPS group, a control group, a lienal polypeptide group and a LPS+ lienal polypeptide group (20 rats in each group). Lienal polypeptide or normal saline was given with an intramuscular injection 30 min after an intraperitoneal injection of LPS (5 mg/kg). The severity of pulmonary injury was evaluated 4 h after LPS challenge by enzyme-linked immunosorbent assay (ELISA), wet-to-dry weight ratio, hematoxylin and eosin (HE) staining, TUNEL and Western blotting. Results Lienal polypeptide injection treatment significantly attenuated LPS-induced pulmonary histopathologic changes, alveolar hemorrhage, and neutrophil infiltration. Moreover lienal polypeptide injection significantly suppressed LPS-induced activation of metastasis-associated protein-1 (MTA1). Conclusion Lienal polypeptide injection is demonstrated to protect rats from LPS-induced acute lung injury by the expression of MTA1.

Objective To investigate the clinical effects of imatinib combined with chemotherapy in adults with Philadelphia-positive acute lymphoblastic leukemia (Ph + ALL). Methods A total of 35 newly diagnosed Ph+ ALL patients from June 2012 to January 2016 in the First Hospital of China Medical University were enrolled. The patients were divided into 21 cases (combined chemotherapy group) and 14 cases (chemotherapy alone group). There were 4 patients in combined chemotherapy group who underwent hematopoietic stem cell transplantation (HSCT) after the first complete remission (CR). The parameters including blood routine, bone marrow morphology, immunoassay, chromosome and fusion genes were detected regularly for efficacy assessment. Results CR rate after the first induction therapy was 76％ (16/21) in combined chemotherapy group and 36％ (5/14) in the chemotherapy alone group, and there was a significant difference of both groups (χ 2 = 5.734, P = 0.033). The median overall survival (OS) time for patients in combined chemotherapy group and chemotherapy alone group were 14 months (2-18 months) and 5 months (0.33-10 months) respectively (U = 12.0, P = 0.007). And the median disease-free survival (DFS) time were 8 months (0-15 months) and 2 months (0-6 months), respectively (U = 12.5, P = 0.007). The median OS and DFS time for transplant patients were 26 months (22-39 months) and 22 months (17-36 months) respectively. Conclusions Imatinib combined chemotherapy can increase CR rate, DFS and OS time for Ph+ ALL patients during the induction therapy, which can gain more chance to receive HSCT. The patients who could receive HSCT as soon as possible after CR1 could get longer survival time.

Objective To explore the impact of peer education on the knowledge ,self-efficacy and behavior of elderly patients with osteoporosis in community. Methods Two communities in Urumqi were sampled by convenient sampling method,and were randomly divided into control community and intervention community. Each community included 73 elderly patients with osteoporosis. In contrast to the community to give regular health education, intervention community to give peer education on the basis of regular health education. The knowledge, self-efficacy and health related behavior scores of osteoporosis were compared between the two groups before and after the intervention. Results Before intervention, the intervention group′ s scores (12.60 ± 2.57, 55.74 ± 2.07, 6.08 ± 1.44) about osteoporosis related knowledge, self-efficacy and health related behavior were like and the control group(12.53 ± 2.90, 55.75 ± 2.05, 6.12 ± 1.04) points. There was no statistically significant difference between the two groups (P >0.05). The post-intervention intervention group(17.02 ± 1.56, 55.74 ± 2.07, 7.01 ± 1.19) scored higher than the control group (15.07 ± 2.02, 55.75 ± 2.05, 6.23 ± 1.35) score on knowledge, self-efficacy, and health- related behavior related to osteoporosis. The difference was statistically significant (P<0.01). Conclusion Peer education model can effectively improve the knowledge, self- efficacy and health-related behavior of the elderly patients with osteoporosis in the community.

In recent years, research on Hodgkin lymphoma (HL) has made great progress. In basic research field, whole exon sequencing and other assay suggest that HL uses multiple genetic mechanisms to escape immune monitoring. In staging and prognosis aspects, PET-CT guided staging and prognostic indicators, as well as some biological indicators may help to stratify patients more exactly; treatment progress includes options of early chemotherapy and radiotherapy, along with efficacy and safety studies of checkpoint blockade, novel treatment regimens as well as updated data of clinical trials. The progress of HL reported in the 60th American Society of Hematology (ASH) Annual Meeting is introduced in this paper.
