Neurofibromatosis type 2 is an autosomal dominant inherited disease with a low incidence. It often involves the central and peripheral nervous systems, leading to bilateral hearing loss, balance difficulties, facial paralysis and other symptoms, which seriously affects the quality of life of patients. Therefore, in the treatment of neurofibromatosis type 2, preservation of facial nerve function is crucial. The diagnosis and treatment scheme should take into account the characteristics of the tumor and the patient′s wishes. Individualized programmes of multidisciplinary collaboration are needed.

OBJECTIVE To analyze the clinical manifestation,diagnosis and treatment of cervical lymph node tuberculosis.METHODS The clinical data of 100 patients with cervical lymph node tuberculosis admitted in our hospital from 2007 to 2015 were retrospectively analyzed.RESULTS Most of the patients with cervical lymph node tuberculosis presented with cervical mass alone,only 8 cases associated with fever,night sweats,fatigue and other systemic symptoms of poisoning.Ninety five patients were diagnosed by postoperative pathological examination,while 15 patients were diagnosed with fine needle aspiration preoperatively.Ninety five patients received surgical treatment with postoperative systemic anti-tuberculosis treatment for 6 months,the remaining 5 patients given standard antituberculosis treatment.All of the patients got satisfactory results.There were three operative methods:simple cervical lymph node resection(31 cases),cervical lymph node dissection(53 cases),and abscess incision debridement(ll cases).All patients had no recurrence.CONCLUSION The clinical manifestation of cervical lymph node tuberculosis are complicated,the positive rate of fine needle aspiration biopsy is low.Postoperative pathological examination can help to further confirm the diagnosis.Surgical treatment combined with postoperative systemic standard anti-tuberculosis therapy can be used to cervical lymph node tuberculosis.

Objective To compare the efficacy of sound therapy and conventional medical treatment in the treatment of chronic tinnitus.Methods CNKI,Wanfang database,Weipu database (VIP),Chinese biomedical literature database (CBM),Pubmed,Embase,OVID,SciVerse ScienceDirect and Cochrane library were used.The data were retrieved up to May 2017,and the relevant literature was screened according to the inclusion and emission standards.The quality of the literatures were analyzed and the data was extracted.Meta analysis was carried out by using Revman 5.2 software with total effective rate,tinnitus handicap inventory(THI) value and visual analogue scale(VAS) value.Results A total of 16 articles (1 594 patients) were included in the literature,including 14 articles in Chinese and 2 articles in English.The total effective rate in the sound therapy group were 86.42 ％ (by patients) and 80.50％ (by ears),while in conventional medical treatment group were 60.62％ (by patients),and 48.10％ (by ear),respectively[P＜0.01 (by patients),P＜0.01 (by ear)].The changes of THI value were analyzed before and after treatment,the difference was statistically significant(P＜0.01).The changes of VAS value were analyzed before and after treatment,the difference was statistically significant (P＜0.05).Conclusion Compared with conventional medical treatment,sound therapy can significantly improve the clinical efficacy of tinnitus treatment and reduce the symptoms in tinnitus patients.

This paper aims to study the effects of traditional Chinese medicine on multidrug resistant human gastric cancer cells in the cell proliferation, migration, invasion and apoptosis, and to study the apoptosis-inducing pathway. Different dilutions of extract were used to process human multidrug resistant gastric cancer SGC7901/ADR cells. Cell proliferation inhibition phenomenon was determined by MTT experiment. Nuclear morphological changes of apoptotic cells and apoptotic indexes were observed and determined by Hochest33528 staining followed with fluorescence microscope observing. Flow cytometry was used to detect cell apoptosis rate. Cell migration and invasion ability were observed and determined by Transwell method. Spectrophotometry was used to detect caspase-3 and caspase-9 enzyme activity. Western blotting was used to detect subcellular distribution of cytochrome c. The results showed that extract had obvious inhibition effect on proliferation of gastric cancer multidrug resistant SGC7901/ADR cells, which was time- and concentration-dependent. After processing multidrug resistant gastric cancer SGC7901/ADR cells with extract, the apoptotic index and apoptosis rate were significantly increased than those in the control group, which showed a time- and dose-dependent mode; but if a caspase inhibitor was added, apoptosis index was not obviously increased. Transwell method showed that migration and invasion ability of the extract-processed SGC7901/ADR cells dropped significantly. Spectrophotometry showed that in extract-processed SGC7901/ADR cells, caspase-3 and caspase-9 expression were increased, which had significant differences with the control group. Western blotting test showed that the distribution of cytochrome c decreased in mitochondria, while increased in the cytoplasm (i.e., cytochrome c escaped from mitochondria to the cytoplasm). In conclusion, extract could inhibit the proliferation, migration and invasion, and induce apoptosis in human gastric cancer multidrug resistant SGC7901/ADR cells; and cytochrome c, caspase-9 and caspase-3 might be involved in cell apoptosis induced by extract, suggesting endogenous or mitochondrial apoptotic pathway.
