OBJECTIVE:
To study the curative effect and prognosis of salvage surgery performed for recurrent laryngocarcinoma.
METHOD:
The clinical data of 43 patients with salvage surgery for recurrent laryngocarcinoma hospitalized in Nanfang Hospital between 2003 and 2011 were analyzed retrospectively. Survival analysis was performed by using Kaplan-Meier method and prognosis factors were analyzed by Log-rank test.
RESULT:
After salvage surgery, 10 (23.3%) patients developed postoperative complications. Pharyngocutaneous fistula and infection occurred in 8 (18.6%) patients. Kaplan-Meier analysis showed that patients survived for 3-year (n = 32) and 5-year 25) after salvage surgery were 56.3% and 32.0% respectively. Univariate analysis indicated that clinical stage in the first diagnosis was significantly correlated with 3 year overall survival (P < 10.05). Local recurrence of laryngeal cavity group and preservation of laryngeal function group had a good prognosis respectively, but no sig nificant difference between them.
CONCLUSION
Salvage surgery is a good choice for recurrent laryngeal carcinoma. Outcomes of these patients were correlated with clinical stages. Laryngeal function preserving surgery for local recurrent laryngeal carcinoma can achieve a expected curative effect and prognosis.

Objective To investigate the effect of early continuous veno-venous hemofiltration (CVVH) on intra-abdominal pressure (IAP) and serum interleukin-6 (IL-6) in severe acute pancreatitis (SAP) patients with abdominal compartment syndrome (ACS).Methods 41 SAP patients with ACS were selected as treatment group and treated with CVVH as well as conventional methods in ICU.The other 12 patients with the same disease were selected as the control group and were only treated with conventional methods because of economic reasons.IAP and blood level of IL-6 in the two groups were measured daily in order to investigate their changes and the correlation between the two parameters.Results The serum IL-6 level and IAP in the two groups were higher on admission day.IAP and serum IL-6 level in the treatment group were significantly decreased on the first day after treatment,and thereafter decreased rapidly.In the control group,IAP and serum IL-6 level were significantly decreased on the 3rd day after treatment.IAP and serum IL-6 level from the 1st day to the 6th day after treatment in the treatment group were significantly lower than those of the control group at the same time point (P<0.05).There was a significant positive correlation between blood IL-6 level and IAP in SAP patients with ACS(r=0.48,P<0.01).IL-6 difference before and after treatment was also positively correlated with the difference of IAP(R=0.39,P<0.05).Conclusions VVH significantly decreased the IAP and the blood level of IL-6 in ACS patients of SAP.The blood level of IL-6 is significantly correlated with IAP,suggesting that IL-6 may play an important role in the pathogenesis of ACS.Therefore early CVVH may clear the cytokines such as IL-6 and lower IAP,thus to prevent multiple organ dysfunction syndrome (MODS),which should be applied in the early stage of ACS.

OBJECTIVETo screen tumor biomarkers in the plasma close related with hypopharyngeal carcinoma.
METHODSPooled plasma from 6 patients with hypopharyngeal carcinoma and 6 healthy individuals were collected. After removal of high-abundance plasma proteins, two-dimensional gel electrophoresis (2-DE) was performed to isolate the total proteins, and the protein spots with more than 2-fold differential expressions were detected by 2D analysis software followed by identification by MALDI-TOF/TOF mass spectrometer. Western blotting was performed to validate the expression level of α2-HS-glycoprotein.
RESULTSA total of 11 differentially expressed protein spots were selected, including 5 upregulated proteins and 6 downregulated proteins. MALDI-TOF/TOF identified the upregulated proteins in hypopharyngeal carcinoma patients as alpha-2-HS-glycoprotein and haptoglobin and downregulated ones as Ig kappa chain C region and apolipoprotein A-I. Western blotting demonstrated that α-2-HS- glycoprotein expression level was consistent with that detected by 2-DE.
CONCLUSIONPatients with hypopharyngeal carcinoma show different plasma protein profiles from healthy individuals. These differentially expressed proteins may serve as potential specific tumor biomarkers for hypopharyngeal carcinoma.

OBJECTIVE:
To analyze the imageology features of benign parapharyngeal space (PPS) tumors, and also to summarize our experience in removing PPS benign tumors through transoral approach.
METHOD:
A retrospective review was conducted to 48 patients with benign tumors in PPS during a 10-year period. CT were performed in all patients, and only a few required MRI. Transoral approach (33.3%) and transcervical (39.6%) were the most commonly performed surgical procedures followed by the transcervical-transparotid approach (27.1%).
RESULT:
CT scan and MRI often provided complementary information to help the surgeons delineate the size, precise location and likely cause of these tumors. After a follow-up of three years, only 2 of 48 patients had disease recurrence. The transoral approach described herein safely allowed for en bloc resection of most benign neoplasms. No significant complications attributed to the approach itself.
CONCLUSION
CT or MRI scan can distinguish prestyloid from poststyloid lesions, and to assess the extension of the tumor as well as its relationship with adjacent structures. The transoral approach safely provides access to some benign PPS tumors with a low rate of complications and recurrence as well as traditional transcervical approaches.

OBJECTIVE:
To compare and analyze the expression difference of proteins between laryngocarcinoma and healthy individuals to search for protein biomarkers that may be detected in plasm of laryngocarcinoma patients.
METHOD:
Pooled plasm from 6 laryngocarcinoma patients and 6 healthy individuals as controls were collected. Two-dimensional gel electrophoresis (2-DE) was used to isolate the total proteins, and the differential protein spots were identified by MALDI-TOF/TOF mass spectrometer, and then the biological information of the proteins was analyzed.
RESULT:
Twenty differential expressed protein spots with more than 1.5-fold between the laryngocarcinoma and healthy individuals were selected, and there were 8 proteins upregulated and 12 proteins downregulated among these proteins. After identifying by MALDI-TOF/TOF, compared with healthy controls, the spots that were L1, C-reactive protein, haptoglobin, ceruloplasmin; the spots that were downregulated were: Serotransferrin, alpha-2-HS-glycoprotein, fibrinogen gamma chain, haptoglobin related protein, Ig lambda-1 chain C regions, Ig kappa chain C region, apolipoprotein A-I, transthyretin, apolipoprotein C-III.
CONCLUSION
Compared with laryngocarcinoma and healthy individuals, the plasm proteins profile showed differently. The proteins of differential expressed are expected to be the specific plasm biomarkers for laryngocarcinoma patients.

Objective:To investigate the value of peripheral blood eosinophils (EOS) in predicting the therapeutic effect of sublingual specific immunotherapy (SLIT) in patients with allergic rhinitis (AR).Methods:From January 2018 to June 2020, 200 patients with AR who received SLIT in Dongguan Kanghua Hospital were evaluated for their symptoms before treatment and 6 months after treatment. The curative effect was evaluated according to the improvement of the total symptom score. The number of eosinophils, percentage of eosinophils in peripheral blood were measured before treatment. The correlation between curative effect and EOS count and EOS percentage was analyzed and the value of these two indicators in predicting the efficacy of SLIT was evaluated.Results:Of the 200 AR patients, 178 patients were confirmed to have completed the treatment course of 6months. 126 effective and 52 ineffective, the effective rates were 70.8%. There was a weak correlation between the number of EOS in peripheral blood and the percentage of EOS in peripheral blood before treatment and the efficacy of SLIT ( r=0.168, P=0.048; r=0.250, P=0.001). The area under the curve of peripheral blood EOS count was 0.380, and the percentage of peripheral blood EOS was 0.355, which were all less than 0.5. Conclusions:There was no significant correlation between the number of peripheral blood EOS count and peripheral blood EOS percentage and the efficacy of SLIT , therefore, both of blood EOS count and blood EOS percentage have no value in predicting the efficacy of SLIT.

OBJECTIVETo investigate a reliable and easy assessment method for swallowing function by evaluating objectively the recovery process of swallowing function in patients six months after supracricoid partial laryngectomy.
METHODSThe swallowing function of patients who underwent supracricoid partial laryngectomy was evaluated six months after operation in Nanfang Hospital of Southern Medical University between January 2013 and February 2014 with two methods, the modified barium swallow (MBS) and fiberoptic endoscopic evaluation of swallowing (FEES), combined with modified penetration aspiration scale (MPAS). Furthermore, the feasibility, reliability and accuracy of these two methods were compared.
RESULTSEleven patients were enrolled. MPAS equals score 1 for solid food, semiliquid food, and liquid food was defined as a criteria of normal swallowing function. By MBS evaluation, the numbers of patients with normal swallowing function were two cases at day 16-30 postoperation, two cases at day 31-45 postoperation, five cases at day 46-90 postoperation, and six cases at day 91-180 postoperation, respectively. By FEES evaluation, the above numbers were three cases, four cases, six cases and eight cases, respectively. When the aspiration was minimal and ejected completely and MPAS was less than or equal to score 4 for solid food, semiliquid food, and liquid food, the gastric tube could be removed. According to this standard, the gastric tube was removed in all cases, and the mean time was (21.7 ± 9.8) days. A good correlation was obtained between these two methods when evaluating solid and semiliquid food, and the Kappa values were 0.802 and 0.844, respectively. However, a little agreement was obtained between these two methods when evaluating liquid food, and the Kappa value was 0.529.
CONCLUSIONSPatients who underwent supracricoid partial laryngectomy could restore good swallowing function in six months after the operation. Both the MBS and FEES are valuable procedures for evaluating objectively the swallowing function in patients after supracricoid partial laryngectomy. The FEES is much better than MBS, because FEES is a simple operation performed alone by otolaryngologists with no radiation.
