OBJECTIVETo investigate the incidence and severity of pulmonary function impairment in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).

METHODSIn this prospective study, fifty-six patients with bilateral CRSwNP who were scheduled for functional endoscopic sinus surgery during a period from March to June 2010 in the Department of Otolaryngology of Qilu Hospital, were recruited in this study. Routine medical and rhinological examinations such as nasal endoscopy, sinus CT scan, and skin prick tests (SPT) for common inhalant and food allergens, and cytological examination of the paraffin-embedded NP tissues were performed together with a full assessment of the pulmonary functions.

RESULTSBased on the pulmonary function tests, the rate of patients showing bronchial hyperresponsiveness (BHR), asthma, and abnormal pulmonery functions were 37.5%, 44.6%, and 53.6%. In patients who did not have a history of lower airway symptoms, the rate of abnormal pulmonary functions was 50.0%, the rate of BHR was 43.2%. There was an increased rate of BHR, asthma and abnormal pulmonary functions in patients with a higher polyp grading score or Lund Mackay CT scan score (polyp grading score: χ(2) were 8.077, 3.989 and 7.445, P < 0.01 or < 0.05. CT scan score: χ(2) were 3.863, 5.380 and 4.309; 4.293, 4.293 and 4.572; 10.572, 13.504 and 13.295, P < 0.01 or < 0.05). The rate of BHR and asthma in patients with positive SPT were higher (P < 0.05). In patients with eosinophils hyperplasia in nasal polyps, the rate of BHR, asthma and abnormal pulmonary functions were higher (χ(2) were 4.065, 5.217 and 3.376, P < 0.05 or P < 0.01).

CONCLUSIONSThere is a high risk of developing lower airway diseases in patients with CRSwNP.

Objective To evaluate the value of serum CEA and CA19-9 concentration for clinical staging of colorectal cancer. Methods A total of 350 patients who underwent the surgical treatments for colorectal cancer between February 2015 to January 2017 were enrolled. The serum CEA and CA19-9 were detected by chemoluminescence method. Results The positive rate of CEA of patients in stageⅠto Ⅳ was 25.00%, 36.69%, 50.78% and 66.67%, respectively. The positive rate of CA19-9 of patients in stageⅠto Ⅳwas 2.94%, 10.07%, 17.97% and 53.33%, respectively. The positive rates of CEA and CA19-9 were gradually increased with the stage developing (P<0.05). Results from multivariate logistic regression analysis showed that the positive levels of CEA and CA19-9 were risk factors in the TNM staging of colorectal cancer. The ORs and 95%CI were 1.790 (1.163-2.755)and 3.476(1.790-6.749), respectively. Conclusion The positive serum concentrations of CEA and CA19-9 showed significant associations with TNM staging. Preoperative serum concentrations of CEA and CA 19-9 could be auxiliary diagnostic indicators to assess the condition of colorectal cancer.

Objective:To explore the effects of 30° and 45° angles on the time and comfort of mechanical ventilation and extubation for patients undergoing abdominal surgery.Methods:A total of 64 patients who underwent oral tracheal intubation at SICU in the General Surgery Center of the Critical Care Medical Center of our hospital from January 2018 to November 2018 were selected. A total of 64 patients were randomly divided into group A and group B by random number table method, of which there were 31 people in group A and 33 people in group B. During the experiment, 1 people in group A and 3 people in group B experienced dyspnea during the withdrawal process and terminated treatment. Finally, 30 patients in group A and 30 patients in group B were selected. The bedside angle during group A treatment was 30°, and the bedside angle during group B treatment was 45°. The bedside angle card was used by both groups to measure the height of the bedside during the weaning. The two groups of patients were compared during the weaning period (improved Visual Analogue Scale score), weaning to extubation time, aspiration rate, intubation time, pressure ulcer rate, pulmonary function and hemodynamic changes after extubation.Results:Patients with ventilator to extubation time, during the machine during oxygenation index, pulled machine comfort score in group A were 117.50 (45.25, 189.00) min, (348.20±59.72) mmHg(1 mmHg=0.133 kPa), 1.00 (1.00, 2.00) points, group B were respectively 30.00 (13.50, 42.75) min, (314.60±67.13) mmHg and 3.00 (2.00, 3.00) points, two groups comparing the difference was statistically significant ( Z values was -2.411, -4.806, t value was 2.048, P<0.05 or 0.01). Conclusion:Lifting the bedside 30° during mechanical ventilation withdrawal in patients with abdominal surgery can shorten the time from patient withdrawal to extubation, improve the patient's oxygenation index, and improve the comfort during patient withdrawal. It can be used as an early patient for abdominal surgery. One of the auxiliary intervention measures for withdrawal.

OBJECTIVETo investigate the relationship between p53 gene intron 7 polymorphism and non-small cell lung cancer (NSCLC).

METHODSOne hundred and five patients with NSCLC and 100 controls were selected with case-control analysis. Polymerase chain reaction (PCR), Apa I restriction enzyme digestion and agarose gel electrophoretic separation were used to identify genotypes of p53 intron 7 in peripheral blood. Then, NSCLC biopsy tissues (n=64) and NSCLC paraffin-embedded tissues (n=40) were selected for mutation analysis. PCR products of p53 exons 5-8 were sequenced on an automated sequencer following the identification of intron 7 genotypes as previously described.

RESULTSIn NSCLC patients, the homozygote positive for ApaI site in p53 intron 7 was 23.8%, the homozygote negative was 12.34%, and the heterozygote was 63.8%. Whereas in control group, the homozygote positive, the homozygote negative and the heterozygote were 44.0%, 11.0% and 45.0%, respectively (P<0.01). In the second part, mutation rate of p53 exons 5-8 was 20.0%, 50.0% and 52.9% in samples with ApaI positive, negative and heterozygotes, respectively (P<0.05).

CONCLUSIONp53 intron 7 ApaI polymorphism may be associated with human NSCLC.

Isoproterenol (ISO)-induced myocardial ischemia animal model has been widely applied to the study of myocardial ischemia and evaluation of drug efficacy. Metabolic profiling of endogenous compounds can make a deep insight into biochemical process of the ISO-induced myocardial ischemia rats. Herein, rats were treated with ISO (2 mg x kg(-1)) for 10 days. After the model was established by measuring myocardial histopathology and plasma creatine kinase, GC/TOF-MS was used to determine endogenous metabolites in plasma and cardiac muscle of rats, and pattern recognition was used to process the data. Results showed that the plasma metabolic profiling of ISO-induced myocardial ischemia rats was significantly different from that of the control, and it had the tendency to the normal state after the discontinue of ISO injection. Besides, the cardiac muscle of rats treated with ISO for 10 days and the normal cardiac muscle could also be separated clearly. The potential biomarkers in plasma and cardiac muscle of model rats had homogeneity and their own specialty. Biochemical metabolic pathway analysis indicated that this myocardial ischemia model was involved in the alternation of energy metabolism, saccharometabolism, lipid metabolism, nucleoside metabolism and amino acid metabolism, and in relationship with oxidative stress. These findings revealed that metabonomics may be a promising tool to evaluate myocardial ischemia rat model induced by ISO and could further extend the study of pharmacodynamic action of drugs at the molecular level.
