Evaluation of swallowing function after cricohyoidoepiglottopexy / 局解手术学杂志

Objective To investigate the evaluation ways and effects of swallowing function after cricohyoidoepiglottopexy(CHEP). Methods Selected 92 patients of glottic carcinoma who were admitted into hospital from February 2014 to January 2017,and all the patients were given cricohyoidoepiglottopexy(CHEP)therapy and function reconstruction.Modified barium swallow(MBS),modified penetration as-piration scale(MPAS),and fiberoptic endoscopic evaluation of swallowing(FEES)were applied after the surgery.And the prognosis of patients was followed up.Results There was one patient who was not able to extubate,and the extubation time of tracheaostomy tube and stomach tube were respectively(12.04 ±5.42)week and(8.00 ±2.19)d among the remaining 91 cases.Three months after operation,the laryngeal function were good in 84 cases,moderate in 6 cases and poor in 2 cases,the incidence of complications was 6.5%.The fundamental frequency and fundamental frequency perturbation three months after operation were significantly lower than thos before operation(P<0.05). With the extension of postoperative time,the MPAS score of patients with MBS and FEES evaluation were obviously decreased(P<0.05). The MBS assessment score were respectively(3.87 ±0.98)points,(1.64 ±0.65)points,(1.09 ±0.33)points at 15 days,30 days and 60 days after operation.The FEES evaluation score were respectively(3.27 ±1.33)points,(1.73 ±1.11)points,(1.18 ±0.89)points at 15 days,30 days and 60 days after operation.With the MBS assessment as the gold standard,the sensitivity of FEES assessment to normal,false aspiration and aspiration were 100%,76.7%and 86.7%,respectively,and the specificity were 86.7%,97.1% and 98.3%,respectively. Conclusion The cricohyoidoepiglottopexy and laryngeal defect repair in the treatment of glottic carcinoma can effectively preserve the laryn -geal function,reduce the incidence of postoperative complications,improve pronunciation function,and the FEES and MBS evaluation of laryn-geal function have good accuracy,and they have good clinical significance to understand the degree of postoperative aspiration.

Influence on cell proliferation by small interfering RNA of Cyclin Y expression in laryngeal cancer cells / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>The effects of lentivirus-mediated suppression of Cyclin Y (CCNY) expression on the proliferation of laryngeal cancer cells were investigated in vitro.</p><p><b>METHODS</b>The lentivirus vectors containing a small hairpin RNA (shRNA) to target CCNY were constructed.Hep-2 cells were divided into the following two experimental groups:the negative control group (control lentivirus infected cells) and CCNY knockdown group (CCNY shRNA-expressing lentivirus infected cells). After Hep-2 cells were infected, Real-time PCR was used to measure CCNY expression. The influence of CCNY on the proliferation of laryngeal cancer cells were assessed using MTT and colony formation experiments.Each experiment was performed in triplicate and repeated three times.</p><p><b>RESULTS</b>Lentiviruses expressing shRNA against CCNY were constructed and Hep-2 cells were infected with above mentioned lentivirus at MOI (Multiplicity of infection) of 120.Real-time PCR analysis showed that the mRNA expression of CCNY in Hep-2 cells in the knockdown group was significantly decreased (P < 0.05); the mRNA level of CCNY was 75.3% lower in the si-CCNY group than in the si-CTRL group. After 5 days of lentiviral infection, the cell viability was significantly lower in cells infected with the CCNY-shRNA lentivirus compared to cells infected with the control lentivirus following a 6-day incubation. The colony number was decreased by 60% in Hep-2 cells infected with the CCNY-shRNA-lentivirus infected cells following a 10-day incubation.</p><p><b>CONCLUSIONS</b>The results suggested that lentivirus-mediated downregulation of CCNY expression decreased the proliferation and growth potency of laryngeal cancer cells.Lentiviruses delivering shRNA against CCNY may be a promising tool for laryngeal cancer therapy.</p>

MicroRNAs regulate epithelial-mesenchymal transition of supraglottic laryngeal cancer / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To study microRNAs (miRNAs) expression profiles associated with epithelial-mesenchymal transition (EMT) in lymph node metastasis of supraglottic laryngeal squamous cell carcinomas(SGLSCC).</p><p><b>METHODS</b>Primary tumor tissue samples of 12 SGLSCC patients were collected, including 6 patients clinically diagnosed with lymph nodes metastasis (N(+)) and 6 patients with lymph nodes metastasis-free (N0), for miRNA microarray gene-expression profiling to identify the differences between N(+) and N0 groups. Differentially expressed miRNAs was verified using quantitative real-time PCR in 20 patients with N(+) and 20 patients with N0. Target genes for the miRNAs associated with EMT in SGLSCC metastasis were analyzed.</p><p><b>RESULTS</b>Ten miRNAs differentially expressed between N(+) group and N0 group were determined. Comparing with N0 group, nine miRNAs were over-expressed and one miRNA was expressed at lower level in N(+) group. The genes for miR-192, miR-143, miR-409 and miR-634 were predicted as target genes that could promote EMT of laryngeal cancer cells by targeted inhibiting Krüppel-like factor 17(KLF17), E-cadherin and phosphatidylinositol 3 kinase (PI3K).</p><p><b>CONCLUSIONS</b>The miRNAs over-expressed in group N(+) can be used to predict cervical lymph node metastasis in SGLSCC. The miRNAs as new markers could improve the diagnosis and treatment of SGLSCC.</p>

Characterization of patients and its relationship with medical complaints / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Patient characteristics may be an internal factor influencing patient complaints, but in China patient characterization is restricted to patient satisfaction surveys, and few studies have considered the relationship between patient characteristics and patient complaints. The aim of this research was to determine the reasons for complaints.</p><p><b>METHODS</b>In this study, we analyzed the characteristics of hospitalized patients and explored their relationship with medical complaints.</p><p><b>RESULTS</b>The significant factors were age (P = 0.045), hospital cost (P = 0.003), household nature (P < 0.001), and education (P < 0.001). The complaint rate decreased when the patients' age increased (regression coefficient, -0.606; OR, 0.545, and 95%CI, 0.301 - 0.987). The complaint rate increased with an increase in hospital cost (regression coefficient, 0.818; OR, 2.266; and 95%CI, 1.320 - 3.889). Patients from non-agricultural households had a higher complaint rate (regression coefficient, 1.051; OR, 2.861; and 95%CI, 1.611 - 5.082). Patients with higher education levels had lower complaint rates (regression coefficient, -0.944; OR, 0.389; and 95%CI, 0.234 - 0.647).</p><p><b>CONCLUSION</b>The survey confirms that older patients and patients with higher education levels had lower complaint rates, while non-agricultural population and patients with higher hospital expenses had higher complaint rates.</p>
