Objective To evaluate the changes in the activity of extracellular signal-regulated kinase 5 (ERK5) in the distal cerebrospinal fluid contacting neurons (CSF-CNs) in the mid-brain of morphine dependent rats.Methods Forty-eight male adult Sprague-Dawley rats weighing 230-270 g,were randomly divided into 2 groups (n =24 each) using a random number table:control group (group A) and morphine dependence group (group B).Morphine dependence was induced by increasing doses of subautaneous morphine for 5 consecutive days.The initial dose of morphine was 10 mg/kg twice a day and was increased by 10 mg/kg everyday until 50 mg/kg on 5th dav.The equal volume of normal saline was injected subcutaneously instead of morphine in group A.On 3rd day after morphine dependence was induced,the distal CSF-CNs in the mid-brain was labeled with 30% cholera toxin subunit B and horseradish peroxidase compound (CB-HRP) 3 μl injected in the lateral cerebral ventricle in the morning.At 4 h after the last injection of morphine,the segments in which CSF-CNs were located were removed,and CB-HRP positive neurons,phosphor-ERK5 (p-ERK5) positive neurons and CB-HRP/p-ERK5 positive neurons were counted.Results Compared with group A,the number of p-ERK5 and CB-HRP/p-ERK5 positive neurons in the mid-brain was significantly increased (P < 0.05),and no significant change was found in CB-HRP positive neurons in group B (P > 0.05).Conclusion The enhanced activity of ERK5 in the distal CSFCNs in the mid-brain may contribute to the development of morphine dependence in rats.

Objective To detect the expression of Cancer-Testis antigen NY-ESO-1 in human laryngeal squamous carcinoma (LSC) and to explore its significance in immunotherapeutic application. Methods The expressions of NY-ESO-1 protein in the LSC and in the pathologically positive lymph nodes were detected by PV-9000 Immunohistochemistry. Western blotting was also employed to measure the expressions of NY-ESO-1 in the tumor core region(TC), the tissues at the sites of 0.5cm, 1.0cm away from LSC periphery and the distant normal larynx tissues. Results NY-ESO-1 protein expression was positive in 30 out of 69 (43.48 %) cases of LSC. The expression level of NY-ESO-1 protein were found to significantly decrease by tums in TC and corresponding adjacent tissues (P <0.01). None of the nine normal larynx tissues expressed NY-ESO-1 protein.It did not display an obvious correlation between the expression of NY-ESO-1 with T staging, pathological grading and lymph node metastasis (P >0.05). Its positive expression was found in pathologically positive cervical lymph nodes, which were significantly lower than that in the primary site (P <0.05). Conclusion NY-ESO-1 protein express at high level in human laryngeal squamous carcinoma, and they may play a role in genesis and development of tumors, which suggests that NY-ESO-1 gene might be used as target antigens for immunotherapy of LSC and the further research is necessary.

OBJECTIVE To observe the submucosal infiltrating extent of laryngeal carcinoma tissue by different location,different T staging and external appearance and to analyze the impact of laryngeal carcinoma submucosal infiltrating extent on surgical margin.METHODS Forty-three laryngeal en bloc specimens coming from 43 cases with laryngeal carcinoma were vertically cut-down along tumor long axis,and were slivered into sections by which laryngeal carcinoma submucosal infiltrating distance was measured under microscope.Laryngeal carcinoma latent submucosal infiltrating extent was compared among different location,different T staging and external appearance.RESULTS Basing on tumor external appearance and infiltrating extent,laryngeal carcinoma was classified into three types:exogenic type,ulcerating infiltrating type and mixed infiltrating type.Of 43 specimens,the three types were 10,8 and 25 cases respectively.There was a significant difference in submucosal infiltrating extent between T1~T2 and T3~T4 laryngeal carcinoma.There was also significant difference in submucosal infiltrating extent between exogenic type and ulcerating infiltrating type or mixed infiltrating type.CONCLUSION The submucosal infiltrating extent of laryngeal carcinoma tissue plays an important role in the surgical margin. As laryngeal carcinoma T stage developing,tumor submucosal infiltrating extent is becoming more extensive.Laryngeal carcinoma submucosal infiltrating extents in ulcerating infiltrating and mixed infiltrating type are more extensive than that in exogenic type.The partial laryngectomy should be prudent to be performed in cases with local advanced ulcerating infiltrating and mixed infiltrating laryngeal carcinoma.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
