Objective To investigate clinicopathological features of scalp angiosarcoma, and to analyze the relationship of tumor stage and treatment with prognosis. Methods Clinical and follow-up data were collected from 16 patients with non-metastatic primary scalp angiosarcoma treated in the Department of Plastic and Reconstructive Surgery of Zhongda Hospital, Southeast University from September 2002 to June 2013. According to the seventh edition American Joint Committee on Cancer (AJCC)TNM staging system for soft tissue sarcomas (2010), staging of scalp angiosarcoma was performed for the 16 patients. Statistical analysis was carried out by the Kaplan-Meier method for survival rates and by the Log-rank test for survival curve. The Cox regression model was used for multivariate regression analysis. Results Of the 16 patients, 4 had stageⅠangiosarcoma, 4 stage Ⅱangiosarcoma, and 8 stage Ⅲ angiosarcoma. The tumor usually began as ecchymosis-like lesions on the head or face in early stage, and progressed into dark red infiltrative plaques, nodules and ulcers which easily ruptured and bled in later stage. Histopathological examination showed generalized vascular proliferation and infiltration with high histological morphological diversity. Cytologic atypia was commonly seen. The median time to recurrence was 15 months, and local recurrence occurred in 7 patients. The median time to metastasis was 20.5 months, and distant metastasis was observed in 8 cases, including 4 cases of pulmonary metastasis, 2 lymph node metastasis, 1 liver metastasis and 1 bone metastasis. The survival time was 33.0 ± 4.4 months (median, 32 months)in 4 patients with stage Ⅰangiosarcoma, 24.0 ± 7.9 months(median, 15 months)in 4 patients with stage Ⅱangiosarcoma, and 23.9 ± 3.9 months (median, 24 months)in 8 patients with stage Ⅲ angiosarcoma. Additionally, the survival time was 23.4 ± 5.2 months(median, 21 months), 24.4 ± 5.7 months(median, 24 months)and 35.8 ± 9.7 months(median, 26 months) in 5 patients receiving surgical treatment alone, 7 patients receiving surgical treatment and radiotherapy, and 4 patients receiving surgical treatment, radiotherapy and immunotherapy, respectively. Conclusions Surgical treatment combined with radiotherapy and immunotherapy may serve as the first-choice treatment for scalp angiosarcoma. Tumor size and treatment regimens are main factors influencing prognosis of scalp angiosarcoma.

Objective To investigate the status of work fatigue of the disabled and the healthy so that we get to know their employment quality and compressive strength, and then provide the theory basis for the national policy formulation and vocational rehabilitation. Methods We randomly investigated 280 employees (220 disabled, 60 healthy people) in 3 companies from 3 provinces with Fatigue Impact Scale (FIS). Results There was no statistically significant difference between disabled and healthy people about work fatigue, and also that of 3 domains including psycho-social, cognitive and physical activity. After comparison of 40 items on FIS,the disabled had higher fatigue than that of the healthy in 4 items which belonged to psycho-social domain (P<0.05). Conclusion Disabled people are no less than healthy people in compression capability and working capability. They should believe in themselves, and their family and the employees should have more confidence about their work capability than before. Government should provide some support with them on job retention.

OBJECTIVETo investigate the feasibility of detecting cyclin D1 protein expression and t(11;14) chromosomal translocation in paraffin-embedded tissues and its diagnostic and differential diagnostic significance for mantle cell lymphoma (MCL).
METHODSParaffin-embedded samples of 36 cases of MCL and a control group of 71 cases of small B-cell lymphomas were retrieved from archive materials. Immunohistochemical staining for cyclin D1 and semi-nested PCR for t(11;14) were detected in all samples. House-keeping gene beta-actin was used to detect the quality of DNA.
RESULTS(1) Cyclin D1 was expressed in 26 of the 36 MCL (72.2%). There was no cyclin D1 expression in the control group. (2) beta-actin DNA was detected in 101 of the 107 tumor cases (94.4%). t(11;14) was detected in 22 of the 36 MCL. Translocation was not found in control group. The positive rate for t(11;14) was 64.7% in MCL after exclusion of 2 cases which were negative for both t(11;14) and beta-actin. (3) 29 cases were positive for cyclin D1 and/or t(11;14), the positive rate reached 80.5%.
CONCLUSIONThe combined detection of cyclin D1 and t(11;14) in paraffin-embedded tissues is found to be a specific and feasible method for diagnosis and differential diagnosis of mantle cell lymphoma.

OBJECTIVETo explore the feasibility of detecting FUS-CHOP fusion gene in formalin-fixed, paraffin-embedded tissue and its application in the diagnosis and differential diagnosis of myxoid/round cell liposarcomas (MRCLs).
METHODSForty-four formalin-fixed, paraffin-embedded MRCL samples and 60 control cases (atypical/well-differentiated liposarcoma, pleomorphic liposarcoma, low-grade myofibrosarcoma, etc.) retrieved from the archival files were studied. Nested reverse transcription-polymerase chain reaction (RT-PCR) technique was employed to detect the FUS-CHOP mRNA expression, followed by DNA sequencing confirmation of the PCR product. Housekeeping gene PGK was used to assess the quality of the mRNA templates.
RESULTSPGK mRNA was detected in 93 of 104 tumor cases (89.4%), including 39 MRCLs cases (39/44, 88.6%) and 90% of the negative control cases. Type II FUS-CHOP fusion transcript was successfully detected in 20 out of 39 (51.3%) MRCL cases. Type I FUS-CHOP fusion transcript was not detected in any MRCLs in this study. All 60 negative control cases were negative for the FUS-CHOP fusion gene transcripts.
CONCLUSIONS(1) Nested RT-PCR can be used to detect FUS-CHOP mRNA in formalin-fixed, paraffin-embedded tissues. (2) FUS-CHOP is considered a specific molecular and genetic hallmark for MRCLs. Nested RT-PCR is a sensitive and specific technique in detecting FUS-CHOP gene, and can be used in the diagnosis and differential diagnosis of MRCLs.

OBJECTIVETo study the effect of anti-CD25 monoclonal antibody (mAb) combined with antithymocytic globulin (ATG) in the treatment of severe steroid-resistant acute graft-versus-host disease (aGVHD) after unrelated donor hematopoietic stem cell transplantation (UD-HSCT).
METHODSTen leukemic patients who developed severe steroid-resistant aGVHD during UD-HSCT received a standard dose of anti-CD25 mAb and a medium or low dose of ATG. The effect on aGVHD control, patients' survival, infection and relapse after the therapy were analyzed.
RESULTSEight of the 10 patients had complete remission and 2 had partial remission after the combined therapy. In the 8 patients with complete remission, 2 developed third degree aGVHD 3-3.5 months after the transplantation, and were managed with a second combined therapy to successfully achieve complete remission. In the total of 12 combined treatments, the median time of therapeutic effect was 5 days (3-10 days); the median complete relief time was 12 days (8-30 days) in the 10 cases. Among the 8 patients who survived for more than 3 months, 7 were diagnosed to have chronic GVHD including 4 with extensive chronic GVHD. No relapse of leukemia was found in these patients. Five patients survived the 2-year-long follow-up after the transplantation with survival time over 2 years; of the 5 patients who died within 2 years after the transplantation, 1 survived for more than one year, and 4 for less than 6 months. Two patients died from invasive fungal infection, two from aGVHD and one from cGVHD-induced multiple organ failure.
CONCLUSIONAnti-CD25 mAb combined with ATG has good therapeutic effect on steroid-resistant sever aGVHD and may help achieve high complete remission rate and long-term survival in leukemic patients after UD-HSCT.

Objective:
To investigate the general situation of scoliosis and influencing factors among middle school students in Guangzhou, so as to provide evidence for behavioral intervention measures.
Methods:
By stratified cluster random sampling method, 2 121 students from 8 middle schools of Guangzhou were selected to conduct questionnaire survey and physical examination.
Results:
The detection rate of scoliosis among middle school students in Guangzhou was 8.20%, girls (9.50%)>boys (7.00%), urban area (10.45%)>suburb area (4.77%), senior high school (10.08%)>junior school (6.39%) ( P <0.05). Among the most of the 174 positive students were found to have large thoracic curve, right lateral bending, being girls with medium scoliosis. Multivariate Logistic regression analysis showed that students in urban area ( OR=2.56, 95%CI =1.71-3.82), with mobile electronic devices usage time≥3 h/d( OR=1.59, 95%CI =1.12-2.27), prolonged near vision work ≥1 h ( OR=1.40, 95%CI =1.00-1.95), outdoor activity time<2 h/d( OR=1.82, 95%CI =1.24-2.67) had a higher detection rate of scoliosis ( P <0.05).
Conclusion
The detection rate of scoliosis among middle school students in Guangzhou is much higher, which might be related to district, mobile electronic devices usage, prolonged near vision work and insufficient outdoor activity. Health education regarding spinal knowledge should be strengthened.

BACKGROUNDPresacral tumors are highly infrequent tumors located in the space known as presacral or retrorectal space. Although there have been substantial improvements in the prognosis of patients with malignant presacral tumors, the development of newer surgical strategy is likely to further improve the oncologic outcomes of malignant presacral tumors. The aim of this article was to report our experience in 33 cases, and to review the surgical strategy, pathological features and the prevention of complications from our experience.
METHODSA retrospective analysis was conducted on 33 cases (20 male and 13 female) with presacral tumors surgically treated in our hospital between January 1998 and April 2009. The surgical approaches included trans-abdominal in 10 cases (30%), trans-sacral in 18 cases (55%) and combined abdominal-sacral in 5 cases (15%). All patients got followed up (14 - 123 months, mean of 45.1 months). At last, the general information, clinical symptoms, histodiagnosis, surgical types and postoperative complications of all cases in our series were assessed.
RESULTSAges of 33 patients ranged from 18 to 71 years, with an average of 48.5 years.
PATHOLOGICAL FINDINGS6 epidermoid cysts, 5 teratomas, 3 leiomyomas, 9 neurofibromas, 5 neurilemmomas, 1 enterogenous cyst, 1 liposarcoma, 1 leiomyosarcoma, 1 angiosarcoma, and 1 neurofibrosarcoma. All tumors were excised with no perioperative death. A colostomy was taken in one case with angiosarcoma involving the rectum because of the intraoperative injury of the rectum. Blood loss during surgery was 400 - 11 000 ml (mean of 2400 ml). Four (12%) cases had local recurrence during follow-up: 2 because of inadequate drainage after dermoidectomy, both of them were cured by surgical resection and drainage; recurrence occurred in a case of teratoma in 18 months after surgery, cured by a trans-sacral excision; local recurrence and lung metastasis occurred simultaneously in a case of angiosarcoma in 6 months postoperatively and the patient died one month later of respiratory failure.
CONCLUSIONSThe main treatment of most presacral tumors is surgical resection. Selection of surgical approach is very important for complete resection of the presacral tumors. The location, size and peculiarities of tumors, conditions of the skin and soft tissues and the patients' somatotype are all determinative factors. Multidisciplinary cooperation is also very necessary.

OBJECTIVETo screen potential serum marker proteins of osteosarcoma, and to make a preliminary bioinformatics analysis of RNA polymerase III polypeptide F (POLR3F).
METHODSGene chip and SELDI-TOF MS was used to screen genes differentially expressed in osteosarcoma. The associations of potential biomarkers from SELDI data and microarray analysis were further inferred by link-test to identify biomarkers that could likely be used for diagnosis. MATLAB was used to search transcription factors binding site in the promoter region and miRNAs binding site in 3'-UTR of POLR3F, respectively.
RESULTS653 differentially expressed genes were found in osteosarcoma cells, while six differentially expressed protein peaks with significant statistical significances were detected by SELDI-TOF MS in patient's serum. 13 potential biomarkers for early diagnosis of osteosarcoma were screened by link-test. A conserved STAT3 binding site and a miRNA target site were found in proximal promoter regions and 3'-UTR region of POLR3F, respectively.
CONCLUSIONSLink-test is a effective method to identify osteosarcoma biomarkers from both microarray and SELDI-TOF MS database. The results confirmed that POLR3F may be a promising biomarker for early diagnosis and a therapy target of osteosarcoma.
