ABSTRACT
OBJECTIVE@#To explore the synergistic immunomodulatory mechanism of interferon alpha-1b, interleukin-2 and thalidomide (ITI) regimen on patients with acute myeloid leukemia (AML).@*METHODS@#Sixty eight untreated de novo or relapsed or refractory or maintenance therapy patients with AML admitted in the Affiliated Cancer Hospital of Zhengzhou University and the other 11 medical units from March 2016 to May 2019 were treated with ITI regimen. Peripheral blood specimen per patient was collected into EDTA-K3 anticoagulation vacuum tube before the administration of ITI and 3 months after the treatment; peripheral blood lymphocyte subsets and perforin and Granzyme B expression were analyzed by using flow cytometry; the levels of VEGF, IFN-γ, TNF-α and IL-6 in the plasma were detected by using a cytometric bead array. Thirty-five healthy subjects from the hospital physical examination centre were selected as normal controls.@*RESULTS@#The ratio of CD4@*CONCLUSION@#The ITI regimen can raise the ratio of CD4

ATM: To define the causes of corneal endothelial cell damage, to investigate the preventive methods, and to observe the variety of corneal endothelial cell in glaucoma using confocal microscope. METHODS: Totally, 143 eyes of 97 patients with different types of glaucoma, and matched normal people were 20 cases, all 40 eyes. The cell density, cell area and cell variable coefficient were measured used confocal microscope. These indicatives of every kind of glaucoma were compared. RESULTS: The corneal endothelial cell density of normal group was 2 893. 88±255. 026/mm2 , the group of acute angle-closure glaucoma ( AACG ) was 1 674. 11±683.95/mm2 , and the group of open angle glaucoma (OAG) was 2687. 22±391. 87/mm2, the group of chronic angle-closure glaucoma (CACG) was 2706. 97±351. 27/mm2. In all index the average cell density of corneal endothelial and the average area have statistical significance ( F =62.950, 8. 795;P=0. 000), especially the group of AACG.CONCLUSION: The index of corneal endothelial cell in AACG is lower than that of normal. All index in OAG and CACG is difference with that of normal, but the difference has no statistical significance. And the dominant factor of damaged corneal endothelial is the time of intraocular hypertension.
ABSTRACT
<p><b>OBJECTIVE</b>To Evaluate the incidence rates and extents of deglutition disorder in patients with laryngeal carcinoma after different types of supracricoid partial laryngectomy.</p><p><b>METHODS</b>Retrospective analysis of postoperative deglutition disorder in patients with laryngeal carcinoma after different types of supracricoid partial laryngectomy treated in our department from 2005 to 2009. The extents of postoperative deglutition disorder were evaluated using a homemade quantitative score table at 5-20 days postoperation.</p><p><b>RESULTS</b>The score of deglutition disorder was 2.71 ± 0.31 in the supracricoid partial laryngectomy-cricohyoidoepiglottopexy (SCPL-CHEP) operation group and 3.43 ± 0.64 in the supracricoid partial laryngectomy-cricohyoidopexy (SCPL-CHP) group, respectively. The deference was statistically significant between the two groups (P < 0.001). The coefficient between age and score of postoperative deglutition disorder was assessed by Pearson correlation analysis. The coefficient of correlation was 0.947 (P < 0.0001) in the SCPL-CHEP group and 0.907 (P < 0.0001) in the SCPL-CHP group. The incidence rate of deglutition disorder was 1/37 in the SCPL-CHEP group and 7/30 in the SCPL-CHP group, evaluated at 8 weeks postoperation (P = 0.012). The deference between the two groups was significant.</p><p><b>CONCLUSIONS</b>The type of operation procedure is an important factor affecting the occurrence of postoperative deglutition disorder in the patients after supracricoid partial laryngectomy, more serious in the SCPL-CHP group. The severity of postoperative deglutition disorder is more serious along with the increase of patient's age. For the elderly (> 70 years of age) patients with laryngeal carcinoma, the choice of surgical procedure should be more cautious, especially with the SCPL-CHP operation.</p>

<p><b>OBJECTIVE</b>To compare the results of extended vertical partial laryngectomy (similar to modified supracricoid partial laryngectomy with cricohyoidoepiglottopexy) and cricohyoidoepiglottopexy in the treatment of laryngeal carcinoma.</p><p><b>METHODS</b>Retrospectively analyzed on the results and prognosis in patients underwent extended vertical partial laryngectomy and cricohyoidoepiglottopexy between 1998 and 2005. The operation was similar to extended vertical partial laryngectomy. The healthy vocal cord and ventricular band as well as about 1/3 to 2/3 laminas of thyroid cartilage were removed. The healthy cricoarytenoid joint was reserved. The vocal cord, ventricular band, fixed or limitation of motion arytenoid cartilage and 2/3 laminas of thyroid cartilage in ill side were removed. The posteroinferior border of laminas of thyroid cartilage in both sides were reserved. The cricoid was lifted and fixed with hyoid epiglottis directly. Extended vertical partial laryngectomy group consisted of 37 patients with glottic carcinoma (stage T2 16 cases, stage T3 21 cases) and cricohyoidoepiglottopexy group consisted of 34 patients with glottic carcinoma (stage T2 12 cases, stage T3 21 cases, stage T4 1 case).</p><p><b>RESULTS</b>Kaplan-Meier analysis was performed to calculate the survival rates. The three-year cumulative survival rate was 91.7% in extended vertical partial laryngectomy group and 87.5% in cricohyoidoepiglottopexy group respectively. There was no significant difference between the two groups (P > 0.05). The five-year cumulative survival rate was 80.6% in extended vertical partial laryngectomy group and 81.3% in cricohyoidoepiglottopexy group respectively. There was also no significant difference between the two groups (P > 0.05). The decannulation rate was 100% (37/37) in extended vertical partial laryngectomy group and 94.1% (32/34) in cricohyoidoepiglottopexy group respectively. The decannulation time was (14.0 + or - 2.3) days in extended vertical partial laryngectomy group and (19.0 + or - 4.6) days in cricohyoidoepiglottopexy group respectively. The incidence of aspiration was 2.7% (1/37) in modified group and 23.5 (8/34) in cricohyoidoepiglottopexy group respectively evaluated at 8th weeks post-operatively. The evaluation of deglutition disorder was analyzed by Ridit analysis in both groups and the results showed that there was significant difference between the two groups (U = 7.341, P < 0.001). The symptom of aspiration in extended vertical partial laryngectomy group was significant less than in cricohyoidoepiglottopexy group.</p><p><b>CONCLUSIONS</b>Although the survival rate was not different between the two groups. The preservation of laryngeal function in extended vertical partial laryngectomy group was significant better than in cricohyoidoepiglottopexy group and extended vertical partial laryngectomy.</p>
