The purpose of this work was to reestablish the respiratory abduction of the paralyzed vocal cord through reinnervation of the posterior cricoarytenoid (PCA) muscle by partial phrenic fibres.In fifteen adult cats the adductor branch of the recurrent laryngeal nerve (RLN) of the right side was cut and its distal end ligated, while its proximal end was implanted into the PCA muscle belly.The whole RLN was then transected in the tracheo-esophageal groove and its distal stump anastomosed to the upper branch of the phrenic nerve.Direct laryngoscopy showed that the inspiratory abduction of the paralyzed vocal cord recovered within 40 d in all cats.80 d later, a larger abducent motion of the glottis was observed on the reinnervated side.Abduction was caused by reinnervation of the PCA muscle from phrenic motoneurons, as demonstrated by laryngeal electromyography and histological testings.The function of the diaphragm was preserved as revealed by monitoring of the intrathoracic pressure.

Recently imageless navigation systems have been developed rapidly, and have become major navigation system in clinic. It comprises computer workstation, infrared optical localizing system, foot control pedal and navigation software. Currently, imageless navigation systems have been used successfully in total knee arthroplasty, uni-compartment arthroplasty, total hip arthroplasty, hip surfacing arthroplasty, total shoulder arthroplasty, anterior cruciate ligament reconstruction and peri-articular osteotomy of knee, etc. The first OrthoPilot imageless navigation system was used by Saragaglia et al in total knee arthroplasty in January 1997, and many clinical studies have been conducted. The clinical results show that this kind of systems greatly improves operative accuracy, and reduce cases beyond ideal range. It shows accuracy as CT-based navigation systems, and they can be commonly used as standard navigation systems in clinic.

Objective To observe the clinical effect of interferon -1 b (Yundesu)in the treatment of verru-ca planae.Methods 1 1 0 patients with verruca pianae were randomly divided into observation group and control group,55 cases in each group.The observation group was given Yundesu injection 30 g once every day in first week, and once every other day in another three weeks.The control group was given orally mannatide 1 0ml two times every day.The leision changes of the two groups were observed after 4 weeks therapy.Results The total effective rate of the observation group was 92.7%(51 /55),which of the control group was 72.78%(40 /55),the difference between the two groups was statistically significant (χ2 =7.70,P <0.01 ).No adverse reactions in the two groups were observed.Conclusion The clinical effect of Yundesu is more prominently beneficial to patients with verruca planae.

Anode is an important part of microbial fuel cell, its performance significantly affects the electricity generation of microbial fuel cells (MFCs). Nanomaterials have excellent properties, such as good conductivity and large surface area. Therefore, nanomaterials modified anode can effectively reduce the electrode resistance, increase the amount of microbial adhesion and improve the electricity generation of MFCs. In this paper, we introduced various nanomaterials modified anodes and summarized their effects on the output performance of MFCs. Finally, the prospect of modifying nanomaterials and technologies were discussed.

Early diagnosis of inflammation and properly interfere to improve the prognosis are very important.However,it is difficult to verify inflammation or differentiate inflammation from infection in clinic,especially in the condition of underlying inflammation.Currently,radiopharmaceuticals based on researches of pathophysiology progress of diseases are studied constantly.This review summarizes the potential inflammation imaging radiotracers and their mechanisms,potential clinical application value.

Molecular targeted therapy (MTT) refers to a new therapy designed to interfere with a specific molecular target or signaling pathway that may have a significant influence in tumor growth or progression. MTT can inhibit cell proliferation and induce apoptosis by specific interventions in the signaling pathways of tumor cells. MTT exhibits potential as an effective treatment against cancer. This approach can improve the ability to kill cancer cells and reduce damage to normal tissues. MTT has gradually been used clinically in treating cancer and shown advantages over traditional methods. This paper reviews research progress in this targeted therapy to treat gynecological cancer.

Objective To explore the microsurgery technique and outcome of expanding translabyrinthine ap-proach resection large acoustic neuroma .Methods We have retrospectively studied clinical data and follow -up re-sults of 4 patients of large acoustic neuroma (≥5 cm ,the largest was 8 cm ;3 cases with servere sensorineualt hear-ing loss ,1 case with high frequenoy hearing loss ;1 case with blindness) in our hospital between January 2013 and April 2013 .All patients received expanding translabyrinthine approach microsurgery to resecting the tumors .Post-operative follow -up was 6~10 months .Results The large acoustic neuroma of 4 cases were totally removed via MRI reexamination after operation .Facial nerve in 3 cases were dissection retained ,and 1 case received facial nerve anastomosis .Six months after operatin ,one patient’s facial nerve function recovered from level Ⅲ to level Ⅱ ,the patient underwent facial nerve anastomosis with facial paralysis level Ⅵ recovered to level Ⅳ ,and the vision of pa-tient with blindness completely recovered to normal .Conclusion The expanding translabyrinthine approach can to-tally resect large acoustic neuroma and preserve facial nerve function .
