Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL) with aggressive behaviour and poor prognosis.Due to the rarity of the disease,few prospective controlled randomized clinical trials were conducted,and the standard therapeutic option for AITL has not been established.Although conventional anthracycline-based chemotherapy achieves response rates of up to 50 ％,most of the patients relapse,the median survival time and overall survival rate are unsatisfactory.Recent studies have demonstrated that hematopietic stem cell transplantation and cyclosporine show promising efficacy in the treatment of AITL.This current review mainly focused on the advance of treatment for AITL.

Objective To explore the regularity of dynamic morphologic changes of the sinoatrial node (SAN) cells of rabbits after the constitution was damaged by formaldehyde wet dressing. Methods Sixty rabbits were randomly divided into 6 groups (n=10 in each group): the control group and 5 experimental groups observed at 2 h, 1, 2, 3, and 4 weeks respectively after the operation. The SAN constitution of rabbits was damaged by 20% formaldehyde wet dressing. The constitutions of SAN were cut quickly at 2 h after wet dressing in the control group and at the corresponding time points in other experimental groups respectively. The specimens were made for light microscopical and electron microscopical observations. The apoptosis of SAN cells was detected by TUNEL method. Results Compared with those in the control group, SAN cells in all experimental groups were damaged at various degrees observed by light microscopy and electron microscopy. Distinct cell tumefaction, soak of grain cells, cytoclasis, hyperplasia of collagen fibers, and other pathological changes were detected. Electron microscopical observation showed distinct pathological changes of the super-micro construction of cells. Apoptosis was not detected in the control group, but various degrees of apoptosis in all experiment groups. The apoptotic rates in all experimental groups were significant as compared with that in the control group (P

Objective:To investigate the expression of miR-126-3p in thyroid cancer and the biological function.Methods:The expression of miR-126-3p in thyroid carcinoma,adjacent tissues and three types of thyroid cancer cells(TPC-1,FTC-133,8505C) were detected by RT-PCR;thyroid cancer cells were divided into analogue group(mimic) and control group(NC),which were respectively with the transfection of miR-126-3p mimic and negative control plasmid.The proliferation and apoptosis in two groups were respectively detected by Brdu-ELISA and flow cytometry.The migration and invasion were detected by Transwell Chambers method.Results:The expression of miR-126-3p in thyroid carcinoma was significantly lower than adjacent tissues(0.384±0.028 vs 0.981±0.039,t=10.291,P<0.05);the expression of miR-126-3p in TPC-1 was the lowest among three types of thyroid cancer cells.Compared with NC group,the proliferation of TPC-1 in mimic group was significantly inhibited,the same with migration(26.68±4.48 vs 82.21±3.65,t=17.789,P<0.05)and invasion(12.28±1.03 vs 34.43±2.10,t=8.103,P<0.05),which the apoptosis was significantly increased[(15.32±3.20)% vs (8.12±1.17)%,t=4.623,P<0.05].Conclusion:The miR-126-3p expression is reduced in thyroid cancer tissue,overexpression of miR-126-3p significantly suppresses the proliferation,migration and invasion of thyroid cancer cells,and promotes the apoptosis,miR-126-3p can play an important biological function as a cancer suppressor gene in thyroid cancer.

As is known, H-Y antigens (male specific minor histompatibility antigens) are a group of minor histocompatibility antigens encoded on the Y-chromosome with homologous H-X antigens on the X-chromosome. H-Y antigens were originally discovered as transplant antigens, and they are only expressed in male individuals without specificity for different tissues and organs. A lot of research results show that H-Y antigens play an important role in the sex selection and identification. The paper reviews the above and discusses the application prospect of H-Y antigen in forensic science.

Objective To assess the effect of surgical repair of medial orbital wall combined with orbital floor fracture via lower lid subciliary approach. Design Retrospective case series. Participants 18 cases of medial orbital wall combined with orbital floor fracture. Methods All patients underwent the reconstruction of orbital wall via lower lid subciliary approach. The composite hydroxyapatite was implanted into the surface of medial orbital wall and orbital floor after lacriminal cyst was completely dissected and protected during the operation. Orbital axial and coronal CT, three-dimension CT scan have been used in all the cases preoperalively and postoperatively. Preoperative CT was compared with postoperative CT. Main Outcome Measures Clinical symptoms and complications. Results All patients were followed up for 3 to 18 months. The postoperative scar of infracillary skin was not obvious. The composite hydroxyapatite was not rejected and dislocated in all cases postoperatively. No postoperative epiphora was found in either case. Preoperative diplopia and enophthalmos were corrected. Conclusion The treatment of medial orbital wall combined with orbital floor fracture via an isolated lower lid subciliary approach was feasible. But the incision was only used in the treatment of inferior medial orbital wall combined with orbital floor fracture, especially the transition area fracture between the orbital floor and medial orbital wall.
