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 .

[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.

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: 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 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.

Objective To investigate the effects of sevoflurane postconditioning on cardiomyocyte apoptosis during myocardial ischemia-repeffusion (I/R) in rats.Methods Forty-five healthy male Wistar rats weighing 250-280 g were randomly divided into 3 groups ( n =15 each):group sham operation ( group S) ; group I/R and group sevoflurane postconditioning (group Spo).The animals were anesthetized with intraperitoneal 3％ pentobarbital 45 mg/kg,tracheally intubated and mechanically ventilated.Myocardial I/R was produced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 120 min reperfusion in groups I/R and Spo.In group Spo the animals inhaled 2.5％ sevoflurane for 5 min starting from 1 min before reperfusion was started.The animals were sacrificed at the end of 120 min reperfusion.Their hearts were removed for measurement of infarct size and the area at risk and determination of apoptotic index (the number of apoptotic cells/the total number of cells) and Bcl-2 and Bax protein and mRNA expression.Results Sevoflurane postconditioning significantly reduced infarct size in group Spo as compared with group I/R.There was no significant difference in area at risk between groups I/R and Spo.Myocardial I/R significantly increased the apoptotic index,Bcl-2 and Bax protein and mRNA expression in group I/R as compared with group S.Sevoflurane postconditioning significantly decreased apoptotic index and Bax protein and mRNA expression but increased Bcl-2 protein and mRNA expression in group Spo as compared with group I/R.Conclusion Sevoflurane postconditioning attenuates myocardial I/R injury by redncing myocardial apoptosis,up-regulating Bcl-2 expression and down-regulating Bax expression.

ObjectiveTo investigate the effect and mechanism of prostaglandin E2 (PGE2) in renin regulation at the juxtaglomerular apparatus (JGA). MethodsMacula densa cell line (MMDD1) was cultured on the special filter. In the medium on the apical lateral of the cells, low concentration of sodium chloride, chloride and different doses of angiotensin Ⅱ (Ang Ⅱ) were used to stimulate the PGE2 secretion. The PGE2 concentration was tested by ELISA. In the animal experiment, the response of plasma renin activity (PRA) to acute intraperitoneal administration of captopril (30 mg/kg) was determined, in conscious wild-type (WT) and cyclooxygenase COX-2-/- mice on C57BL/6 genetic backgrounds. PRA was measured in plasma obtained by tail vein puncture. Different concentrations of PGE2 were used to stimulate the renin secretion of primary cultured JGA cells from COX-2-/- mice and wild type mice. In specific Gsα gene delete mice (low renin producing mice), 24 h urine was collected to test the concentration of PGE2. The COX-2 mRNA and protein of the kidney cortex were observed by real-time PCR and immunohistochemicul staining. ResultsLow chloride could stimulate the PGE2 secretion both at the apical and basement of the macula densa cells. In COX-2-/- mice, the base PRA and were obviously lower than wild type mice. Captopril could stimulate the PRA of (COX)-2-/- mice increasing 32.8 times. But Ang Ⅱ had no effect on PGE2 secretion in macula densa cells. In primary cultured JGA cells, the decreasing renin seretion was partly recovered by PGE2 in cells from COX-2-/- mice. In low renin producing mice, the expression of COX-2 mRNA in the kidney cortex increased by (8.07±1.08) times (n=6, P=0.0022). The COX-2 protein of the kidney cortex and the urine PGE2 increased by several times. ConclusionsLow chloride is the primary stimulation messenger of PGE2 secretion in macula densa cells. The PRA in COX-2-/- mice can be stimulated by angiotensin converting enzyme inhibitor, but the Ang Ⅱ has no direct effect on macula densa cells. When renin production is abolished in JGA cells (Gsα delete mice), COX-2 mRNA and protein up-regulation is observed in kidney cortex and macula densa. PGE2 plays an important role in regulation of renin secretion and renin release in JGA by precise feedback mechanism.

OBJECTIVE To investigate the proliferation effect of di(2-ethylhexyl) phthalate (DEHP) on prostate in aged rats at the environmental exposure dose and the possible mechanism.METHODS Thirty-two male Sprague-Dawley rats,aged 1.5 years,were randomly divided into 4 groups (8 rats per group) and treated with DEHP (30,90 and 270 μg· kg-1,ig) and vehicle once daily respectively for 4 weeks.All the animals were anesthetized with pentobarbital sodium and sacrificed on the day subsequent to the last treatment.① Abdominal aortic blood samples were collected,and serum estradiol (E2),testosterone (T) and prolactin (PRL) levels were assayed by ELISA.② The prostate tissues were dissected and categorized into different lobes,weighed and measured.The prostate relative mass was calculated.③ The morphological changes were detected by HE staining and prostate epithelial height was analyzed with microscopic image analysis software.RESULTS Compared with vehicle control group,the prostate relative mass,dorsolateral prostate mass,and dorsolateral prostate index in DEHP 270 μg· kg-1 group were significantly higher (P＜0.05).The height of the ventral prostate epithelium in DEHP 30,90 and 270 μg· kg-1 groups was increased significantly (P＜0.01),so was the height of dorsal prostate epithelium in DEHP 270 μg· kg-1 group (P＜0.01).There were no significant changes in levels of E2,PRL or T in DEHP 30,90 and 270 μg· kg-1 groups,but the ratios of E2/T in DEHP 30 and 270 μμg· kg-1 groups were increased significantly (P＜0.05).CONCLUSION Low-dose DEHP could promote the proliferation of prostatic hyperplasia in the aged rats,which might be associated with the relative levels of endogenous hormone.
