Objective To study the out come of coblation arytenoidectomy combined with true and false pos-terior cordectomy for treatment of bilateral vocal cord paralysis (BVFP) .Methods The group included 17 patients (8 incomplete BVFP and 9 complete BVFP) .All the patients had waited more than 6 months before surgery with no spontaneous recovery .The patients underwent arytenoidectomy combined with true and false posterior cordecto-my using coblation under video suspension laryngoscope .Electric fibrolaryngoscope was performed before and after operation to evaluate the size of the glottis .The patients'voices were recorded before and after operation and evalua-ted by 3 laryngologists through GRBAS .Results Preoperational laryngoscope showed that in the incomplete BVFP ,the vocal folds were close to the middle line with limited abduction .In the complete BVFP ,the vocal folds failed in adduction and abduction and the size of the glottis was 2 -3mm .3 of the patients had underwent tracheotomy . Post operational electric fibrolaryngoscope showed proximate triangulate breathing space which was more than 4mm in the posterior glottis .The patients were followed up 6 to 44months .15 of the 17 were allowed for decannulation . One patient among them underwent posterior cordectomy and arytenoidectomy on the contralateral side respectively after the first operation because of dyspnea owing to scar diathesis .Two patients bunged up the canula but did not de-cannulate .Among them one was a 8-year old boy diagnosed as congenital heart disease .One was thyroid cancer with stiff neck due to radiology .The only postoperative complication was the appearance of granulations in the operation region in 2 patients ,which were disappeared spontaneously .Quality of the voice improved in 2 patients ,unchanged in 10 and worsened in 5 .Conclusion This study demonstrates that arytenoidectomy associated with posterior cord-ectomy is a satisfactory surgical treatment of bilateral vocal fold paralysis because it leads to a considerable and stable enlargement of the breathing space and preserved the voice quality .

In 40 cases of headache treated by hydroacupuncture plus Tuina, in comparison with 35 cases treated with medications plus Tuina, the results showed that the therapeutic effect was better in the treatment group than in the control group.

Transient receptor potential vanilloid 1(TRPV1)is a nonselective cationic channel,and can be activt-ed by capsaicin,protons and heat.TRPV1 plays a critical role in the initiation of neural inflammatory response and the pathway of pain signal transduction.As a new analgesics,TRPV1 antagonists block pain behaviors in models of inflammatory,neuropathic,and cancer pain.A number of pharmaceutical companies developed a range of TRPV1 antagonists with various structures.It was found that various chemotypes of TRPV1 antagonists would cause an increase in body temperature(hyperthermia),which may become concerns for their development.This article summarizes the recent progress in TRPV1 antagonists development and the relevant hyperthermia.

[Objective] Examine the expression of Galectin-3 (Gal-3),B cell lymphoma-2 protein (Bcl-2) in epithelial ovarian cancer tissues with regard to clinicopathological and survival variables,testing whether they can serve as prognostic markers and provide evidence for further research.[Methods] 98 EOC tissues and 10 normal ovarian tissues were collected,as well as their clinical documents.The expression of Gal-3 and Bcl-2 was tested via immunohistochemical staining analysis.Then the correlation between these two proteins and the clinicopathological and survival variables of these patients were evaluated.[Results] Of the 98 EOC,Gal-3 and Bcl-2 were all cytoplasmic staining.Gal-3 was observed in a majority of the EOC tumor cell proper (75/98,76.5％) but not in normal ovarian tissues.Bcl-2 was observed in a majority of the EOC tumor cell proper (50/98,51.0％) but not in normal ovarian tissue.Spearman bivariate correlation test show that there was no correlation between the expression Gal-3 and Bcl-2 (P =0.867).Gal-3 expression in EOC was associated with histology and platinum sensitivity (P =0.043,P =0.038),while Bcl-2 was associated with FIGO stage (P =0.029).Cox univariate analysis revealed that Gal-3,Bcl-2 expression,platinum sensitivity,stage were associated with overall survival (P =0.008,P =0.021,P ＜ 0.001,P ＜ 0.001).Further multivariate analysis showed that only Gal-3 expression,platinum sensitivity,stage affected the survival of these patients (P =0.014,P =0.021,P ＜ 0.001).[Conclusions]The expression of Gal-3 and Bcl-2 in EOC was significantly higher than that in normal ovarian tissue,supposed that they may involve in the development and progression of EOC.Gal-3 expression was associated with histology,platinum sensitivity and survival,it may be an independent predictive factor for EOC prognosis.There was no correlation between the expression Gal-3 and Bcl-2 in EOC,the functional mechanism between these two protein need further research.

OBJECTIVE: This study conduct a qualitative synthesis and quantitative meta-analysis of VFAFI, aimed to study whether it is a useful treatment for UVCP. METHOD: Electronic databases PubMed, YZ365. COM, WANFANG DATA, CMJD, CHKD,CNKI were searched using relevant keywords. Reported treatment outcomes were clustered into three categories,i. e. subjective, perceptual,acoustic,aerodynamic,and stroboscopic. Meta-analyses were performed on studies with numerical results using random effects model. RESULT: Five articles were identified with a total of 404 patients. All the studies reported significant improvements or decrease after VFAFI in each category of outcome measurements. Meta-analysis demonstrated a significant increase or decrease in all categories. Adverse effects include slight inflammatory reponse can resolve spontaneously within 1 month. The recurrence rate after VFAFI was high due to the self absorption. NNE and Jitter of post-operation is lower than pre-operation,there is no significantly change between the control group and experimental group; F0, Shimmer and MPT of post-operation is higher than pre-operation, there is no significantly change between the control group and experimental group. CONCLUSION The invasiveness and morbidity of VFAFI are low and the side effects are self-limited. Meta-analyses demonstrated significant improvements or decreased from both objective and subjective measurements. Further controlled studies with longer follow-up periods and more person were included may evaluate the effectiveness of VFAFI more reliably.

Objective To investigate the clinical efficacy and adverse events of methimazole ( MMI ) treatment for children with hyperthyroidism, and to identify the predictors of remission and relapse. Methods A total of379children(260girlsand119boys)diagnosedwithhyperthyroidismandtreatedbyMMIinGuangzhouWomenand Children's Medical Center from March, 2004 to July, 2014 were retrospectively analyzed. The average age at diagnosiswas(9.3±2.3)years(range2.0~15.9years). Results AftertreatmentwithMMIfor3and6months, the thyroid functions of 96. 3%(365/379) and 98. 9%(375/379) patients returned to normal, respectively. By the end of this study, 256(67. 5%) patients continued to use MMI treatment and 44 patients(11. 6%) dropped out. 79 patients(20. 8%) achieved remission, 35 patients (44. 3%) of whom experienced a later relapse. Children who achieved constant remission had significantly lower FT3 and FT4 levels at diagnosis compared with the relapsed children(P<0. 05 or P<0. 01). It was more likely to remain long-term remission for children turned to be euthyroid within 3 months after initiating MMI treatment(P<0. 05). The relieved patients with family history of thyroid diseases weremorelikelytoberelapsed(P<0.05). Therewerenosignificantdifferencesinage,gender,exophthalmos, initial goiter size, thyroid peroxidase autoantibody, and thyroglobulin antibody levels between the relieved and relapsed patients. The overall incidence of adverse events associated with MMI was 27. 7%, mainly elevated alanine aminotransferase, bilirubin, and neutropenia. Most(66. 7%) of adverse events occurred within the first three months of MMI treatment. Conclusion MMI has a good effect on pediatric hyperthyroidism, with low remission and high relapse rate. The low thyroid hormone concentrations at diagnosis and normalization of thyroid function within three months seem to be useful predictors of remission. Vigilance is needed concerning MMI-associated adverse events throughout the MMI treatment period, especially during the first trimester of MMI initiation.

Objective To compare the effect between intra-arterial and intra-venous neoadjuvant chemotherapy(NACT)in stage Ⅰb2-Ⅱ b cervical carcinoma.Methods A retrospective analysis Was done on 52 cases of intra-venous NACT and 95 eases of intm-arterial NACT for stage Ⅰ b2-Ⅱ b cervical carcinoma treatad in Peking Union Medical College Hospital from 1999.ResulIs The response rate of intraveHous NACT and intra-arterial NACT was 88%(46/52)and 79%(75/95).and the operative rate after NACT Was 81%(42/52)and 72%(68/95)respectively(P>0.05).There were no significant differences in surgery time,blood loss and pest-operative morbidity between these two groups.Pathological parametrial positive rate after NACT in arterial group(6%)Was significantly lower than that of venous group (50%,P>0.05).The venous group had very similar recurrence rates(13%vs 17%)and death rates (9%VS 12%)when compared with the arterial group(P>0.05).Conclusions The intra-arterial and intra-venous NACT for stage Ⅰ b2-Ⅱb cervical carcinoma show similar response rate.operative rate and surgical difficulties.Arterial NACT shows a better effect on parametrial infiltration.

AIM:To explore the influence of exogenous hydrogen sulfide ( H2 S) on coagulation and fibrinoly-sis in ferric chloride ( FeCl3 )-induced mouse carotid artery thrombosis .METHODS: The mice were divided into sham control group, model group, different concentrations (12.5, 25 and 50μmol/kg) of sodium hydrosulfide (NaHS, H2S do-nor) groups and 30 mg/kg clopidogrel ( positive control ) group.Intraperitoneal injection of NaHS at different concentra-tions and oral administration of clopidogrel bisulfate were performed for 3 d prior to FeCl 3-induced carotid artery thrombo-sis.The frozen sections of the carotid artery were collected to perform HE staining , and the thrombus pattern and the chan-ges of vascular pathology were observed .The thrombus was weighed to calculate thrombosis inhibitory rate .Prothrombin time ( PT) , activated partial thromboplastin time ( APTT) , fibrinogen ( FIB) and fibrinogen degradation product ( FDP) in the mice were also measured by a coagulometer .The plasma levels of thromboxane B 2 ( TXB2 ) , 6-keto-prostaglandin F 1α(6-keto-PGF1α) and plasminogen activator inhibitor (PAI) were detected by ELISA.RESULTS: Compared with model group, NaHS dose-dependently inhibited the formation of carotid artery thrombus .NaHS treatment reduced the contents of TXB2 and PAI, and recovered 6-keto-PGF1αcontent in thrombosis model group .In NaHS treatment groups , 6-keto-PGF1α/TXB2 and thrombus weight was negatively correlated .NaHS treatment prolonged PT and APTT , reduced the content of FIB, but increased the level of FDP in thrombosis model group .CONCLUSION:Hydrogen sulfide prevents FeCl 3-induced carotid artery thrombosis by inhibiting coagulation and activating fibrinolysis .

Objective To discuss the effects of different drying methods on composition and antioxidative activities of the volatile oil fromCymbopogon citrates; To optimize the best drying method for Cymbopogon citrates. MethodsCymbopogon citrates was dried by drying in the sun, drying in the shade and oven drying at 40℃. Volatile oil was extracted by steam distillation. Chemical constituents in the volatile oil were analyzed by GC-MS and the antioxidative activities were determined by ferric reducing antioxidant power (FRAP method).Results Extraction rate of the volatile oil fromCymbopogon citratesunder the environment of freshness, sun drying, shade drying and oven drying at 40℃ were 0.25%, 1.21%, 1.19% and 1.17%, respectively; after dried by different methods, main constituents and antioxidative activities of the volatile oil fromCymbopogon citrates were basically same. Conclusion Different drying methods have little influence on composition and antioxidative activities of the volatile oil fromCymbopogon citrates. Oven drying at 40℃ was the best way to dryCymbopogon citrates.
