OBJECTIVE: To study the efficacy of treatment with microsurgery in combination with local injection of type A botulinum toxin for vocal process granuloma. METHOD: 28 patients with vocal process granuloma received endotracheal intubation under general anesthesia. The lesion was removed with micro-scissor and CO2 laster under a self-retaining laryngoscope and microscope. The incision and mucous membrane surrounding the wound was closed with 8-0 absorbable suture. 4-point injection of botulinum toxin type A 8-15 u was then performed along the thyroarytenoid muscle and arytenoid muscle of the same side. Postoperative medication was administered based on disease causes. RESULT: All patients experienced vocal cord dyskinesia of the injected side 2-3 days after surgery. At 1 month after the surgery, wound healing was good in all the 28 patients, and the vocal cord movement was limited at the injected side. At 3 months, movement of the bilateral vocal cords was normal, and the vocal cord process mucosa was smooth. Patients were followed up for more than a year, and only one patient had recurrence in 2 months after surgery. The cure rate was 96. 4%. CONCLUSION Combination of laryngeal microsurgery and type A botulinum toxin local injection can shorten the treatment course of vocal process granuloma.

This study was aimed to investigate short-term modulation mechanism of scalp acupuncture according to the experimentation of cortical excitability and motor-related cortical potentials in ten normal volunteers.Through scalp needle stimulation in specific theoretical areas related to underlying cerebral surfaces,scalp acupuncture can be used as an effective therapy by changes in relative cerebral function,which is the basic principle.According to the available neurophysiological data in our study,the modulation of scalp acupuncture displayed in late part of motor-related cortical potential noticed mainly in the motor and sensory cortexes,contralateral to the needle stimulate site.Also,acupuncture can develop inhibition at longer interstimulus intervals,in paired pulse magnetic stimulation,from the somatosensory input of contralateral sensory cortex via scalp needle stimulation.In our study,it might be difficult to produce more acupuncture inhibition.The maintaining of scalp needles subcutaneously without other management after achieving needling sensations cannot achieve the requested strength of the acupuncture stimulation.

Abstract BACKGROUND:Studies have found that Cu-Zn superoxide dismutase (SOD1) is associated with familial amyotrophic lateral sclerosis, opening up a new way of studying molecular genetics. So far more than 100 kinds of SOD1 gene mutations have been found. OBJECTIVE:To analyze the hot spot, research front and knowledge base of amyotrophic lateral sclerosis visualy. METHODS:Totaly 4 693 relevant articles published from 2005 to 2014 were retrieved from Web of Science in ISI with “Cu-Zn superoxide dismutase” or “SOD1” as search keywords. With the aid of CiteSpace III software, the visualization mapping of the network in co-cited articles and keywords was drawn to reveal knowledge base, hot spots and research front of SOD1. The parameters include the number of published papers and citations within 10 years, distribution of research countries and institutions, main source journals, research area of highly cited papers, keywords with high-frequency and emerging keywords with high-frequency in recent 5 years. RESULTS AND CONCLUSION:The number of published papers and citations in a year showed a trend of sustained growth. United State, China and Japan rank the top three in this area, in which Chinese Academy of Sciences has a great influence among the research institutions. The research fields of SOD1 focus on neurosciences and neurology, biochemistry and molecular biology and so on. The high impact factors of journals with a large number of articles reflect the importance and innovation of this research. Ten high-cited articles consist of the knowledge base on SOD1, directing to the finding of different sites of SOD1 mutation and the measurement of protein concentrations and activity of SOD. The hot spots of SOD1 mainly focus on oxidative stress, familial amyotrophic lateral sclerosis caused by SOD1 mutation and different types of transgenic animal models. The research fronts mainly focus on the finding of pathogenesis in amyotrophic lateral sclerosis, such as the aggregation of TDP-43, the interaction between astrocytes and motor neurons, optineurin and the inhibitor of nuclear factor-κB, hexanucleotide repeat expansion in C9ORF72 and autophagy.

Objective To explore the effect and side effects of Group A Streptococcus Preparation(Sapylin)com-bined with mitomycin and lentinan combined with mitomycin in treating malignant pleural effusion through intrapleural catheter.Methods 70 malignant pleural effusion patients were selected in this study.All the patients were randomly divided into Sapylin group and lentinan group.One case with penicillin positive of the Sapylin group was adjusted to enter the lentinan group.After drainage of pleural effusion,the patients were divided into Sapylin group (34 patients) and lentinan group (36 patients).For the Sapylin group,Sapylin was prior injected and mitomycin was posterior injected.For the lentinan group,lentinan was prior injected and mitomycin was posterior injected.The side effects and clinical effect were observed and reported.Results The effective rate of Sapylin group was 85.3%,whereas 83.3%of lentinan group.There was no significant difference between the two groups(χ2 =0.051,P =0.822).Both groups had the following minor side effects:chest pain,fever,vomit and decreased white blood cells.No liver or renal injuries were reported.Conclusion The clinical outcomes of Sapylin combined with mitomycin and lentinan combined with mitomycin are both positive,in addition,the side effects are minor.

Acupuncture was frequently used for alternative treatments in Parkinson's disease because of its safety,but there was an argument whether acupuncture improves motor symptoms or not.Besides,few electrophysiological studies were designed for acupuncture combined with Parkinson's disease Using the technique of paired transcranial pulse magnetic stimulation,we measured the excitability of corticocortical inhibitory circuits to investigate effects of scalp acupuncture from 9 patients with Parkinson's disease.Although patients didn't take any short-term benefit in motor symptoms through the treatment of scalp acupuncture,there was no any adverse event,and some electrophysical effects developed in patients.The enhanced corticocortical inhibition on motor cortex possibly developed at longer interstimulus intervals,and there was a relatively increase in later part of motor-related cortical potentials on the central part and right-side near vertex around over sensory cortex,but was not significant in early potentials.So a further long-term study is essential to ascertain the physical mechanism and clinical effects in scalp acupuncture.
