In recent years,more and more experts and scholars study enhancer of zeste homolog 2 (EZH2) and the relationship of the overexpression of EZH2 gene with the occurrence,development,metastasis,and prognosis of tumor,to explore the early diagnosis of cancer,monitoring metastasis and judging the prognosis to provide the new ideas and the methods,to provide the reference for the basic and clinical research.

Methods involved in the treatment of malignant tumor are surgical therapy, radiotherapy, chemotherapy and immunotherapy. Although some effects have been showed in tumor therapy, the limits of single use of those methods can not be avoided. Therefore, combined therapy has been pursued in order to achieve better results. The effects of those combined methods such as chemotherapy combined with cytokine, chemotherapy combined with tumor vaccine, chemotherapy combined with adjuvants have been approved both experimentally and clinically. These results, in some extent, will provide us a new way to fight against tumor.

ObjectiveTo discuss the diagnosis and therapy of primary presacral tumor. Methods23 patients with primary presacral tumors underwent surgical treatment from 1983～1999 were studied retrospectively. ResultsIn respect to pathological type, congenital tumor was the most frequent one in 23 patients. Digital examination together with B ultrasound and CT examination were quite important in determining the extent and degree of tumor invasion. As for operative ways, transacral and transperineal approach were the most common choices to detect the tumor. Conclusion Complete and enbloc resection is the principal method in treating presacral tumor, whether the lesions are beign or malignant. Choices of operative way should be made accordial to tumor condition. Keep nerves and blood vessels from being injuried during operation.

Infectious diseases have emerged as one of the leading causes of morbidity and mortality in systemic lupus erythematosus(SLE)patients,so early diagnosis of infectious complication in SLE patients is absolutely beneficial for patients' prognosis.C-reactive protein(CRP)and Procalcitonin(PCT)can help to differentiate infections with active SLE in SLE patients.Serum KL-6 can help to distinguish pulmonary involvement of SLE from infections in SLE patient.The most common pathogens for infection in SLE patients are bacteria,but more attention should be paid to viral and fungal infections,which have been on a rise recently.

Objective: To evaluate the feasibility of performing muscle-sparing thoracotomy and intercostal sutures in the treatment of upper and/or middle thoracic esophageal cancer for the purpose of tumor control and postoperative quality of life improvement.Methods: Seven patients with esophageal cancer were treated with vertical muscle-sparing thoracotomy and Mckeown esophagectomy.Detailed clinic data were summarized and analyzed with patient follow-up information.Results: Of the 7 patients,five were still alive with a 71.4% five-year survival rate.There were no deaths resulting from the operation in this group.The mean length of thoracic incision was 11 cm.The range of hospital stays was 14 to 25 days,with a mean length of 18 days.No patients complained of impaired shoulder action,and the incision pain was hardly perceived without external stimulation 1 month after operation.Conclusion: Performing the muscle-sparing thoracotomy in the treatment of early-stage esophageal cancer located in the upper and /or middle thoracic segment yields a satisfactory long-term survival rate with an improved life quality in terms of incision pain relief and shoulder function.

Leptin receptor plays an important role in the modulation of energy metabolism and lipid equilibrium after binding with Leptin. Leptin receptor locates widely in the human tissues and is closely linked with obesity. This manuscript reviews the structure of leptin receptor gene and its relationship with obesity, and discusses the role of leptin receptor in obesity development and therapy.

OBJECTIVEThis study aims to evaluate the effectiveness of arthrocentesis on Wilkes III stage patients. Clinical examinations and magnetic resonance imaging (MRI) findings before treatment and six months after treatment were compared and analyzed.

METHODSA total of 137 outpatients diagnosed with temporomandibular joint internal derangement (TMJID) associated with Wilkes III stage through clinical examination and MRI findings from January 2013 to December 2013 were randomly included. All the patients were successfully treated with arthrocentesis. Moreover, all the patients accepted clinical and MRI examination before arthrocentesis treatment and six months after. Clinical examination included visual analogue scale and opening degree, whereas MRI examination included articular disc morphology and effusion in the upper compartments. Statistical analysis was performed using SPSS 20.0.

RESULTSResults showed that the average score of visual analogue scale six months after treatment was significantly lower than that before treatment (P < 0.05). The success rate was 78.1% (107/137). The rate of disc deformity after arthrocentesis treatment was higher than that before the treatment. By contrast, the positive rate of effusion after arthrocentesis was significantly lower than that before the treatment (P < 0.05). Bilaminar zone adaptive changes (disk-like) were found in seven cases (5.1%, 7/137) after treatment.

CONCLUSIONArthrocentesis could effectively relieve pain of the TMJID patients. Furthermore, MRI results indicated that arthrocentesis could significantly decrease articular effusion. Arthrocentesis was effective for the treatment of Wilkes III stage in the short term. Adaptive changes in bilaminar zone occurred in a few patients. However, serious disc deformity with the passage of time is a trend that has been observed.
