Objective To observe the tolerance of contemporaneous multiplane operations in obstructive sleep apnea-hypopnea syndrome(OSAHS). Methods Twenty-three patients were enrolled. According to the different obstructive level, the different operations were chosen to complete upper airway reconstruction in contemporaneous operation group (group A, 13 patients). In the simple palatopharynx level obstructive group (group B, 10 patients), bilateral tonsillectomy and H-UPPP was chosen. Results The operation time in group A was significantly longer than that in group B:(121.0 ± 35.4) min vs.(80.7 ± 25.3) min, P<0.01. The hospital days and adverse events in two groups had no significantly difference (P>0.05). Conclusions Individual therapeutic schedule for OSAHS patients should be formulated. Operating the different obstructive levels simutaneously, which would solve upper airway occlusion and complete the upper airway reconstruction at the same time. No more adverse events happen, compared with the simple palatopharynx level obstructive group, though the operation time may be longer.

Objective To evaluate effects of acitretin and interferon?α(INF?α)alone or in combination on the proliferative activity of and interleukin?15 expression in human cutaneous T?cell lymphoma Hut78 cells. Methods Cultured Hut78 cells were divided into several groups, including blank control group, negative control group, dimethyl sulphoxide (DMSO) group and experimental groups. Cells in experimental groups were additionally classified into several subgroups to be treated with acitretin(0.1-10μmol/L, acitretin groups)or INF?α(5 000-20 000 IU/ml, INF?αgroups) alone, or the combination of 1.0 μmol/L acitretin and IFN?α at concentrations of 5 000- 20 000 IU/ml (combination groups), for 24, 48 and 72 hours. Subsequently, cell counting kit 8(CCK8)assay was performed to assess the proliferative activity of Hut78 cells, and enzyme?linked immunosorbent assay(ELISA)to measure the expression of IL?15 in these cells. Results The proliferative activity of and IL?15 expression in Hut78 cells were both obviously suppressed in the acitretin groups and combination groups compared with the DMSO group, as well as in the INF?αgroups compared with the negative control group, and the inhibitory effects gradually increased with the increase in acitretin or INF?αconcentrations and treatment durations. As repeated measures analysis of variance revealed, there was a significant difference in both proliferation inhibition rates and IL?15 expression among different treatment durations and among different concentrations of acitretin or INF?α(all P<0.05), and there was an interaction effect between treatment durations and drug concentrations(all P<0.05). A significant difference was observed in both proliferation inhibition rates and IL?15 expression at 24, 48 and 72 hours when the 1.0?μmol/L acitretin+ 10 000/20 000?IU/ml IFN?αgroup was compared with the 1.0?μmol/L acitretin group and 10 000/20 000 IU/ml IFN?αgroup(all P<0.05). There was also a significant difference in IL?15 expression at 24, 48 and 72 hours between the 1.0?μmol/L acitretin+50 000?IU/ml IFN?αgroup and 5 000?IU/ml IFN?αgroup(all P<0.05). Conclusions Acitretin and IFN?αboth can inhibit the proliferation of and IL?15 expression in Hut78 cells, the inhibitory effects are enhanced with the increase in drug concentrations and treatment durations, and the combination of acitretin and IFN?α appears to have stronger inhibitory effects than acitretin or IFN?αalone.

BACKGROUND: The aims of this study were to evaluate the abilities of direct sequencing (DS), peptide nucleic acid (PNA) clamping, and pyrosequencing methods to detect epidermal growth factor receptor (EGFR) mutations in formalin-fixed paraffin-embedded (FFPE) non-small cell lung carcinoma (NSCLC) samples and to correlate EGFR mutational status as determined by each method with the clinical response to EGFR tyrosine kinase inhibitors (TKIs). METHODS: Sixty-one NSCLC patients treated with EGFR TKIs were identified to investigate somatic mutations in the EGFR gene (exons 18-21). RESULTS: Mutations in the EGFR gene were detected in 38 of the 61 patients (62%) by DS, 35 (57%) by PNA clamping and 37 (61%) by pyrosequencing. A total of 44 mutations (72%) were found by at least one of the three methods, and the concordances among the results were relatively high (82-85%; kappa coefficient, 0.713 to 0.736). There were 15 discordant cases (25%) among the three different methods. CONCLUSIONS: All three EGFR mutation tests had good concordance rates (over 82%) for FFPE samples. These results suggest that if the DNA quality and enrichment of tumor cells are assured, then DS, PNA clamping, and pyrosequencing are appropriate methods for the detection of EGFR mutations.

Objective Atherosclerosis is widely accepted as a chronic inflammatory disease. Serum biomarkers for vulnerable plaques not only serve as diagnostic tools for the identification of patients with acute coro-nary syndrome, but also assist the identification of high-risk patients. However, the existing data are limited and conflicting. In the present study, we determined whether the plasma levels of interleukin-1β (IL-1β) are correlated with adverse cardiac outcomes in patients with ST-evaluate acute myocardial infarction (STEAMI) undergoing pri-mary percutaneous coronary intervention (PCI). Effect of the plasma intedeukin-1β level on prognosis of patients with ST-segment elevation acute myocardial infarction. Method This prospective single-center study included 96 patients with SIEAMI with onset < 12 h who underwent primary PCI, 271 patients with stable angina pectoris (SAP) and 148 control subjects without coronary artery disease who were consecutively admitted to hospital be-tween Mar, 2006 and Mar, 2008. Plasma IL-1β levels were measured by enzyme-linked immunosorbent assay in all subjects. The patients with STEAMI were then followed prospectively for the occurrence of major adverse car-diac events (MACE) (including cardiovascular death, non-fatal myocardial infarction, heart failure, and cardio-genie shock) during hospitalization. We determined the association between IL-1β levels with the risk of MACE using multivariate logistic regression. Results Compared with the SAP patients and control subjects, patients with STEAMI had higher levels of IL-1β (P < 0.05). During hospitalization, 32 patients (33.3%) experienced MACE [23 males, 9 females; age: (75.44±13.45) years]. In the STEAMI patients, IL-1β was elevated in patients with MACE compared with patients without MACE (median [range]: 26.52 [12.010 to 155.244] pg/mL vs 2.157 [0.433 to 83.021] pg/mL; P < 0.01) by non-parameter analysis. Significant and positive correlations be-tween IL-1β and cardiac troponin-I (cTnI) (r = 0.353, P =0.004) were observed by Spearman's correlations analysis. Multivariate logistic regression analysis revealed that IL-1β levels ≥20 pg/mL were significantly and in-dependently associated with MACE during hospitalization (odds ratio: 32.05; 95% confidence interval: 4.28 to 240.151; P =0.001). Conclusions The present study revealed that patients with STEAMI had elevated IL-1β levels on admission. The plasma IL- 1β level is an independent inflammatory predictor for in-hospital MACE in pa-tients with STEAMI undergoing percutaneous coronary intervention.

Objective To analyze the complications of adenoidectomy assisted with ablation under nasal endoscope. Method Two hundred and seventy-two cases of adenoidectomy assisted with ablation under nasal endoscope from April 2014 to April 2018 were retrospectively studied. The type, number, causes and processing methods of postoperative complications were analyzed. Results There were 67 cases (24.63％) with atlantoaxial rotatory deformity, 27 cases (9.93％) with fever, 11 cases (4.04％) with headache, 4 cases (1.47％) with postoperative recurrence, and 1 case (0.37％) with secondary postoperative haemorrhage. Conclusions The technology of adenoidectomy assisted with ablation under nasal endoscope is an efficient and minimally invasive method with less complications in the treatment of children adenoidectomy diseases. Atlantoaxial rotatory deformity is a common postoperative complication which is easy to be ignored by clinical doctors. The prognosis is good, after given a positive symptomatic treatment.

PURPOSE: The anaplastic lymphoma kinase (ALK) gene is a potential molecular target in non-small cell lung carcinoma (NSCLC). The clinicopathologic implication of a change in the ALK gene copy number (GCN) is unclear. MATERIALS AND METHODS: A total of 434 primary NSCLC samples were analyzed by fluorescence in situ hybridization (FISH) for ALK GCN. RESULTS: Ninety-six cases (22.1%) showed ALK GCN gain with amplification in 16 (3.7%) cases. The cases with ALK GCN gain consisted of 47 adenocarcinomas (49.0%), 41 squamous cell carcinomas (42.7%), 5 adenosquamous carcinomas (5.2%) and 3 other NSCLCs (3.1%). ALK gene amplification was identified in 7 adenocarcinomas (43.7%) and 9 squamous cell carcinomas (56.3%). There was no significant difference between ALK GCN gain/amplification and histologic subtypes. Univariate survival analysis revealed that patients with ALK GCN gain/amplification showed shorter progression-free survival durations and decreased overall survival rates (p<0.001). However, multivariate analysis proved that ALK GCN gain/amplification is not an independent prognostic factor for progression-free survival or overall survival. CONCLUSION: ALK GCN gain is frequently identified in NSCLCs and the incidence is similar among histologic subtypes. Although ALK GCN gain/amplification is not an independent prognostic marker, it is associated with tumor progression in NSCLC.

BACKGROUND: The role of excision repair cross-complementation group 1 (ERCC1) has been controversial in non-small cell lung cancer (NSCLC) patients who received adjuvant chemotherapy with a platinum agent. We investigated ERCC1 expression in stage I-II NSCLC to clarify its significance for adjuvant chemotherapy. METHODS: The ERCC1 expression profile was evaluated by immunohistochemistry and compared according to adjuvant chemotherapeutic agents in 146 patients who underwent surgical resection for stage I-II NSCLC. The patients were divided into 3 groups; adjuvant chemotherapy with a platinum based agent (18.5%, 27/146); adjuvant chemotherapy with uracil-tegafur (UFT) (40.4%, 59/146); surgery-alone (41.1%, 60/146). RESULTS: Nuclear ERCC1 expression was detected in 71.9% (105/146) of NSCLC and was significantly associated with a shortened survival period in the group 1 patients who received the platinum based regimen after surgery. The group 2 patients who received UFT showed the longest survival period, followed by the surgery-alone group (overall survival, p=0.049; disease-free survival [DFS], p<0.001). CONCLUSIONS: These results suggest that stage I-II NSCLC patients with ERCC1 expression experience a shorter DFS period with adjuvant chemotherapy with a platinum based regimen and may benefit from adjuvant chemotherapy with UFT, instead of platinum after surgery.

BACKGROUND: Alterations in the phosphatase and tensin homolog (PTEN) are correlated with tumor progression. Downregulation of PTEN is related to drug resistance of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in non-small cell lung cancer (NSCLC). The aim of this study was to evaluate the prognostic significance of PTEN in patients with NSCLC and its correlation with EGFR. METHODS: Two hundred eighty eight surgically resected NSCLC samples, including 168 adenocarcinomas (ADCs), 99 squamous cell carcinomas (SCCs) and 21 other NSCLCs were analyzed for the PTEN. The results were correlated with other clinicopathological variables including EGFR amplification and mutation. RESULTS: Loss of PTEN was detected in 42.4% of NSCLCs, specifically 28.6% of ADCs, 66.7% of SCCs, and 38.1% of others. Loss of PTEN was significantly associated with SCC, smoking, male gender, and higher stage. In a multivariate analysis, loss of PTEN was significantly associated with short progression-free survival (p=0.037). No association between PTEN and EGFR was observed. CONCLUSIONS: These results suggest that loss of PTEN results in shorter progression-free survival in patients with NSCLC, and loss of PTEN is more associated with SCC, smoking, male gender, and higher T stage by the 7th tumor, node and metastasis staging system but not EGFR status.
