Mycosis fungoides (MF) is the most common subtype of primary cutaneous T-cell lymphoma, and its pathogenesis remains unclear. Recent studies have uncovered high-frequency chromosomal copy number variations in MF, such as gain of chromosomes7q,1q,17q and loss of 9p21,10q,17p, which lead to the gain of proto-oncogenes and loss of tumor suppressor genes, and finally result in tumor development and progression. Moreover, low-frequency single-nucleotide variants have been found in MF, and these mutated genes are mostly enriched in the pathways associated with cell cycle regulation, cell apoptosis, chromatin remodeling as well as T cell activation. Gene-fusion variation is rarely reported in MF. In addition, large cell transformation may occur in some MF cases, and often indicates poor prognoses such as disease progression and drug resistance. In conclusion, MF is a complex disease with highly molecular genetic heterogeneity, and more extensive and intensive researches on its pathogenesis are needed in the future.

Objective To investigate the practicability and safety of laparoscopic anatomical hepatectomy.Method 40 patients with space occupying lesions in the liver underwent laparoscopic anatomical hepatectomy between Jan.2008 and Mar.2012.The diagnoses were hepatocellular carcinoma (HCC) (n=13),recurrent HCC (n =1 ),cholangiocarcinoma ( n =1 ),metastatic cancer ( n=6),hepatolithiasis (n=10),hemangioma (n=7),FNH (n=1) and liver cell adenoma (n =1).Intraoperative ultrasound was routinely performed to locate lesions and intrahepatic structures.Selective hemihepatic vascular occlusion was applied during resection. High frequency cautery,CUSA and Ligasure were used to transect liver parenchyma. Hemolocks were applied when large blood vessels and bile ducts were encountered.Endo-GIA was used if necessary.The operations included right hemihepatectomy (n =3),left hemihepatectomy (n =10),resections of segment Ⅴ and Ⅵ (n=5),segment Ⅴ (n=3),segment Ⅵ (n =4),and segment Ⅳb (n =1).Result34 hepatectomics were performed laparoscopically.6 patients were converted to open surgery.There was no perioperative death. The operating time was 250.21±50.94 min,and intraoperative blood loss was 420.20± 120.10 ml.Bile leakage was diagnosed in 2 patients after operation.Conclusion With careful patient selection,and improvement in surgical technique and apparatus,laparoscopic anatomical hepatectomy has become safe and practicable.The operation has the advantages of minimal invasion and rapid recovery. It can be regarded as a standard procedure for selected benign and malignant lesions.

Objective To obtain I50 anti-idiotype antibody and identify its activity in vitro.Methods I50 anti-idiotype (Id) antibody gene was amplified from the template of fuse 5-I50 by PCR to construct a prokaryotic expression vector pET25b-I50. The expression of pET25b-I50 in E. coli BL21(DE3) was induced by isopropylthio-β-D-galactopyranoside (IPTG) and was confirmed by SDS-PAGE and Western blot with Ab1(FC2) monoclonal antibody and an anti-hexahistidine tag antibody. The method of dialysis refolding was used to restore the activity of I50 anti-Id antibody, which was measured by Dot-ELISA and lymphocyte proliferation assay. Results The recombinant vector was successfully constructed and the recombinant protein was successfully expressed and purified with 90% purity. The relative molecular weight of the expressed protein was 15 kD, which was in accordance with expectation. The activity of I50 anti-Id antibody could be restored and could promote the proliferation of lymphocyte in a dose-dependent manner. Conclusion These results suggested that I50 anti-Id protein vaccine is likely an option in the therapy against nasopharyngeal carcinoma in vivo.

Objective To investigate the safety and long-term therapeutic results of anatomical hepatectomy for hepatocellular carcinoma (HCC).Methods 90 patients underwent anatomical hepatectomy from January,2003 to January,2010.The tumor size was ≤5 cm in 38 patients,and ＞5 cm in 52 patients.The tumor number was a single lesion in 58 patients,and multiple lesions in 32 patients.Cirrhosis was present in 46 patients (55.42％); cancer embolus was present in 34 patients (37.78％).There were 64 patients in Child-Pugh A and 26 patients in B.The operating time,blood loss and blood transfusion were recorded and analyzed.Complications and liver function were monitored after surgery.The Kaplan-Meier method was used to calculate the survival rates.Log-rank test was used to analyze factors associating with postoperative recurrence.Independent factors influencing tumor-free survival and overall survival were analyzed by Cox-model logistic regression.Result There was no perioperative death.The incidence of complications was 31.1％ (28/90).The recurrence rate was 51.1％ (46/90).The 1-,3-,5 year tumor-free survivals were 92.2％,67.3％ and 49.7％％00,respectively.Positive resection margin and satellite nodule were independent factors for recurrence (RR19.22,95 ％ confidence interval 5.85～63.17).The 1-,3-,5-year overall survivals were 94.4％,80.0％ and 60.0％,respectively.Positive resection margin and TNM were independent factors for overall survival (RR 2.013,95％ confidence interval 1.28～3.17).Conclusions Anatomical hepatectomy was a safe and efficacious procedure to treat HCC.Positive resection margin and TNM were independent factors associated with overall survival.Anatomical hepatectomy had the advantages in ensuring a lower rate of negative resection margin.
