A case of laryngeal carcinoma complicated with Hodgkin's lymphoma / 临床耳鼻咽喉头颈外科杂志

A case of laryngeal cancer complicated with Hodgkin's lymphoma treated in the Department of Otolaryngology Head and neck surgery of the First Hospital of Jilin University was reported. Under general anesthesia, right vertical partial laryngectomy, bilateral neck lymph node functional dissection and temporary tracheotomy were performed. No recurrence was found in laryngoscope and color Doppler ultrasound of neck lymph nodes 3 and 5 months after operation.

Comparison of BRAF mutation detection in patients with papillary thyroid microcarcinoma by ARMS and direct sequencing / 中国免疫学杂志

Objective:To investigate the sensitivity and the specificity of scorpions amplification refractory mutation system ( ARMS) in comparing with that of direct DNA sequencing in the detection of BRAF gene mutations in patients with papillary thyroid microcarcinoma.Methods:Direct sequencing and ARMS were used simultaneously to detect BRAF mutation status in 56 patients with PTMC.Results:BRAF mutations were identified in 46 cases with a mutation rate of 82.9%by ARMS,while in 18 cases with a mutation rate of 32.1%by direct sequencing.Besides,the sensitivity of ARMS was 100%and that of direct sequencing was 39.1%.There were significant differences of both mutation rate and sensitivity between two methods ( P<0.01 ).Conclusion: Compared to direct sequencing,ARMS gains a higher sensitivity in the detection of BRAF mutations in samples with tiny lesions.

Advances on treatment of myasthenia gravis / 中国实用内科杂志

Myasthenia gravis(MG)is an acquired autoimmune disease,which is mediated by nicotinic acetylcholine receptor(AChR)antibody,depends on cellular immunity and involves some complements.It mainly affects AChR on the postsynaptic membrane at the neuromuscular junction(NMJ).Various therapeutic methods have been used in the treatment of MG,but current therapeutic methods can not do well when used alone,and most current drugs have major side effects due to immunosuppression,We expect that novel therapies be discovered.
