Background and purpose:Patients with colorectal cancer are often accompanied by the increase of plasma ifbrinogen concentration. This study aimed to investigate the distribution characteristics of beta-ifbrinogen gene-448G/A, -148C/T, -1420G/A and -854G/A polymorphism and plasma ifbrinogen (Fg) concentration in patients with colorectal cancer. Furthermore, we analyzed their effects on the occurrence and development of cancer.Methods:The level of plasma Fg was quantiifed by using Clauss clotting method.FGBβ gene polymorphisms were identiifed by re-al-time lfuorescence quantitative PCR (RTFQ-PCR) in 194 colorectal cancer patients and 74 healthy controls.Results:The plasma Fg levels in tumor metastasis group and non-metastasis group were signiifcantly higher than that in control group, respectively (P<0.05). Compared with control group, the frequencies of -148T allele and mutation genotype were notably higher in disease group (P<0.05). In all the groups, the plasma Fg levels of those with -148T allele were higher than those without -148T allele (P<0.05). In stageⅣ patients, there was no difference in PFS between -148T wild gen-otype group and mutation genotype group (P>0.05).Conclusion:Plasma Fg concentration in patients with colorectal cancer was signiifcantly raised, which suggests that Fg may play a role in the occurrence and development of colorectal cancer. The beta-ifbrinogen gene -148C/T polymorphism is one of the reasons that cause plasma Fg elevation, but has no correlation with prognosis of patients with stageⅣ colorectal cancer.

Objective:To investigate the relationship between surface hydrogen form and the bioactivity of titanium.Methods:Sandblast titanium was etched with the combination of sulfuric and hydrochloric acids(SLA group,n=3 ).Then etched titanium was heat at 450 ℃in air(SLA+HT group,n=3).Surface topography,roughness,hydrophility,surface chemical texture were observed. Finally,the titanium samples were soaked in body simulate fluid for 3 days,the mineral deposition properties were observed by X-ray diffraction.Results:Titanium hydride was formed on the titanium surface after etching.After heat treatment,surface texture and roughness were not changed,titanium hydride decomposed and hydrophility increased.More hydroxyapatite was found on the surface of the samples treated by SLA+HT and followed by SBF.Conclusion:Titanium hydride can not improve the bioactivity of titanium, heat treatment may increase the mineralization.

Objective To analyze the correlation between anxiety symptoms and abnormal brain function in patients with chronic obstructive pulmonary disease (COPD) under long-term chronic hypoxia. Methods Twenty-one patients with COPD complicated with anxiety were prospectively selected as COPD group, and 26 healthy individuals matched for gender and age were selected as control group. Both groups underwent high-resolution 3D-T1-weighted imaging (3D-T1WI), T2-fluid-attenuated inversion recovery (T2-FLAIR), and blood oxygen level dependent (BOLD) sequence examination. DPARSF and SPM8 software were used to analyze the amplitude of low-frequency fluctuations (ALFF) in the brain of the two groups. Results In the COPD group, the ALFF value in the left parahippocampal gyrus-cingulate gyrus increased, and the ALFF value in the right superior frontal gyrus decreased (P < 0.05). Pearson correlation analysis found that there was a negative correlation between the ALFF value in the right superior frontal gyrus and the anxiety score (r=-0.485, P=0.03). Conclusion Chronic hypoxic patients with COPD have brain functional impairment in the right superior frontal gyrus, and the degree of impairment is positively correlated with anxiety symptoms. There may also be compensatory enhancement of brain function activity in the parahippocampal gyrus-cingulate gyrus.

Objective: To construct a nursing intervention program for patients with coronary heart disease based on the theory of Omaha intervention system, and to provide evidence for the specialist nursing of patients with coronary heart disease. Methods: Based on the Omaha intervention system, the specialist nursing intervention plan for patients with coronary heart disease was preliminarily established on the basis of reviewing the medical records, and was modified by the Delphi method. Results: Reviewing the medical records combined with the Omaha intervention system, preliminary development of nursing intervention programs for patients with coronary heart disease. The expert inquiry letter of the intervention program was 2 rounds, and the expert positive coefficients of the 2 rounds of inquiry letters were 91.67% and 93.94%, the authoritative coefficient was 0.92, and the Kendall Harmony Coefficient was 0.34 and 0.47 respectively. The specialist nursing intervention for patients with coronary heart disease was finally determined. Conclusion The nursing intervention plan for patients with coronary heart disease based on Omaha theory has a good theoretical basis and has been unanimously recognized by experts.

Objective: To explore the feasibility of applying Omaha system theory to patients with coronary heart disease (CHD) through comparative analysis of nursing description. Methods: Using content extraction analysis method, the nursing records, nursing plans and nursing measures of discharged patients with CHD were retrieved from the medical records, and then the conceptual consistency of the extracted records and the problem classification system and intervention measures in the Omaha system were evaluated by cross mapping method. Results: A total of 2 609 nursing problems and intervention measures were extracted from the medical records of 68 patients with CHD. Among them, 1 844 (70.68%) records were labeled as "perfect fit", 608 records (23.30%) as "partial fit", and 157 (6.02%) recordsas "not fit at all". The total fit rate was 93.98% (perfect fit and partial fit). The most frequently reported problems were in physiological domain, followed by health-related behaviors domain, psychosocial domain and environmental domain. The nursing interventions extracted accounted for 26.67% (1 968 sentences) of directions and l00.00% (4 kinds) of categories in the intervention scheme of Omaha system. Conclusions The conceptual congruence between the medical records of patients with CHD and the Omaha System is quite high. It can help to improve nursing problems of patients of CHD in health-related behavioral domain, psychosocial domain and environmental domain, and can be applied to such patients after appropriate adjustment, so as to help clinical nursing staff to provide specialized and all-round guidance for patients with CHD.

OBJECTIVE: To explore the diagnostic yield of bronchoscopic rapid on-site evaluation (B-ROSE) in patients with severe invasive bronchopulmonary aspergillosis (IBPA) and provide evidence for starting antifungal treatment before microbiological results were available. METHODS: A prospective cohort study was conducted to select patients with severe pneumonia suspected of IBPA admitted to the respiratory intensive care unit (RICU) in the First Affiliated Hospital of Xinjiang Medical University from June 2014 to June 2022, and those who were primarily infected with other pathogens (such as bacteria, Mycobacterium tuberculosis) at admission were excluded. Whether the antifungal treatment was initiated or not on the basis of the bedside B-ROSE, the B-ROSE was administered as soon as possible within 24 hours after admission to RICU. The current international definition of invasive aspergillosis was used as the gold diagnostic standard, the diagnostic accordance rate, the sensitivity and specificity of B-ROSE were calculated respectively, and the receiver operator characteristic curve (ROC curve) was also plotted, to evaluate the predictive value in diagnosing IBPA. RESULTS: A total of 176 patients with severe pneumonia suspected of IBPA were included in the study. According to international diagnostic standards, there were 81 cases of IBPA and 95 cases of non-IBPA. According to the early diagnosis of B-ROSE, there were 89 cases of IBPA and 87 cases of non-IBPA. The diagnostic accordance rate of B-ROSE was 84.09% (148/176), the area under the ROC curve for B-ROSE in diagnosing severe IBPA was 0.844, the 95% confidence interval (95%CI) was 0.782-0.905, the sensitivity was 87.65%, the specificity was 81.05%, the positive predictive value was 79.78%, the negative predictive value was 88.51%, the rate of underdiagnosis was 12.35% (10/81), and the rate of misdiagnosis was 18.95% (18/95). Compared with the true negative group, the proportion of long-term (≥ 14 days) use of glucocorticoid [70.0% (7/10) vs. 9.1% (7/77), P < 0.01] and the proportion of cases with diabetes [40.0% (4/10) vs. 10.4% (8/77), P < 0.05] were significantly higher in the false negative group (underdiagnosis group). However, B-ROSE of both groups showed mucosal bleeding, congestion and edema [100.0% (10/10) vs. 94.8% (73/77), P > 0.05], indicating that acute mucosal inflammation was non-characteristic. Compared with the true positive group, the proportion of long-term (≥ 14 days) use of glucocorticoid in the false positive group (misdiagnosis group) was significantly reduced [33.3% (6/18) vs. 60.6% (43/71), P < 0.05]. The B-ROSE results showed the proportion of cases with mucosal white spots, black plaques and pseudomembrane was significantly reduced [16.7% (3/18) vs. 52.1% (37/71), P < 0.01] in the misdiagnosed group, which suggest that cases of long-term use of glucocorticoid and cases with B-ROSE showing mucosal white spots, black plaques and pseudomembrane were less likely to be misdiagnosed. The main diseases that were easily misdiagnosed as IBPA included pulmonary tuberculosis (38.9%, 7/18), inflammatory lung adenocarcinoma (27.8%, 5/18) and pulmonary vasculitis (16.7%, 3/18). CONCLUSIONS Before obtaining microbiological evidence, B-ROSE can assist in decision-making of early anti-aspergillus treatment for severe IBPA. This method is prompt, simple, and has high accuracy and reliability. If B-ROSE lacks characteristic manifestations, especially for severe pneumonia in patients with long-term use of glucocorticoid or diabetes, attention should be paid to the underdiagnosis of IBPA. Diseases such as lung tuberculosis, inflammatory lung adenocarcinoma and lung vasculitis should be vigilant against misdiagnosis as IBPA.

Objective:To investigate the influencing factors of endotracheal intubation and mechanical ventilation (ETI-MV) in patients with acute respiratory distress syndrome (ARDS) caused by viral pneumonia, and to provide evidence for individualized use of ETI-MV.Methods:Patients with ARDS due to viral pneumonia admitted to the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed from November 2017 to March 2022. The gender, age, concomitant diseases, clinical symptoms and signs, complications, lab results, ARDS severity, infectious virus type, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), respiratory support methods and prognosis-related variables were collected. Univariate analysis was performed on each factor, and the variables with statistical significance in the univariate analysis were subjected multivariate logistic regression analysis. The receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive value of each index for the implementation of ETI-MV.Results:A total of 117 patients were enrolled in the study, including 61 patients in the ETI-MV group, and 3 patients (4.9%), 39 patients (63.9%) and 19 patients (31.1%) with mild, moderate and severe ARDS, respectively. There were 56 patients in non-ETI-MV group, and the mild, moderate and severe ARDS cases were 16 cases (28.6%), 38 cases (67.8%) and 2 cases (3.6%), respectively. There was significant difference between the two groups ( P < 0.05). Univariate analysis showed that during 24 hours admitted to RICU, the levels of interleukin-6 [IL-6 (ng/L): 104.0±90.0 vs. 62.4±76.0], oxygenation index [PaO 2/FiO 2 (mmHg, 1 mmHg≈0.133 kPa): 123.9±30.9 vs. 173.6±28.5], the proportion of cases with pulmonary infiltrating opacity distribution range ≥ 3/4 lung fields [85.3% (52/61) vs. 21.5% (12/56)], APACHE Ⅱ score ≥ 16.5 [67.2% (41/61) vs. 42.9% (24/56)], the rate of nosocomial invasive aspergillus infection [14.8% (9/61) vs. 3.6% (2/56)], the percentage of nosocomial bacterial infection [16.4% (10/61) vs. 3.6% (2/56)], and the lowest CD4 + T lymphocyte count in the course of the disease [cells/mm 3: 192.2±35.8 vs. 215.0±58.3] had significant differences between ETI-MV and non-ETI-MV group (all P < 0.05). Multivariate Logistic regression analysis showed that during 24 hours admitted to RICU the distribution range of pulmonary infiltrating opacity ≥ 3/4 the lung fields [odds ratio ( OR) = 12.527, 95% confidence interval (95% CI) = 3.279-47.859, P < 0.001], APACHE Ⅱ score ≥ 16.5 ( OR = 30.604, 95% CI = 4.318-216.932, P = 0.001), PaO 2/FiO 2 ( OR = 0.948, 95% CI = 0.925-0.972, P < 0.001), CD4 + T lymphocytes cell count ( OR = 0.975, 95% CI = 0.955-0.995, P = 0.015), and nosocomial bacterial infection ( OR = 38.338, 95% CI = 1.638-897.158, P = 0.023) were independent risk factors for ETI-MV. The area under the ROC curve (AUC) of ROC showed that PaO 2/FiO 2 had the greatest predictive value for ETI-MV, with AUC of 0.903, sensitivity of 91.1% and specificity of 95.1% in case of cutoff value of 151 mmHg. The AUC of pulmonary infiltrating opacity distribution range was 0.809, the sensitivity of 85.2%, specificity of 78.6% when the cutoff value was ≥ 3/4 lung field. APACHE Ⅱ scores had the lowest predictive value for selecting ETI-MV, with AUC of 0.704, sensitivity of 83.6% and specificity of 57.1% under the cutoff value was 16.5. Conclusions:For patients with ARDS caused by viral pneumonia, PaO 2/FiO 2 is still the classic reference for selecting ETI-MV, however, the distribution range of pulmonary infiltrating opacity and the systemic severity of the disease during 24 hours admitted to the RICU may provide supplemental helpful information to determine whether the patients choose ETI-MV, especially for moderate ARDS.

Objective: Endometrial carcinoma (EC) is one of the most common gynecological malignant tumors. Our study showed that long non-coding RNA (lncRNA) linc01194 plays an important role in EC. We explored the mechanism of lncRNA linc01194 in EC. Methods: The expression of lncRNA linc01194 was detected in The Cancer Genome Atlas database and starBase database. The potential targeted protein of linc01194 was predicted through the starBase database. To determine the role of linc01194 in EC, we downregulated or upregulated the level of linc01194 in EC cell lines and analyzed the cell behaviors and the changes of its potential target proteins. Results: The expression of linc01194 in EC tissues is higher than that in normal endometrial tissues. The knockdown of linc01194 inhibited the cell proliferation, invasion and migration and promoted the apoptosis of EC cells, while overexpression of linc01194 promoted cell proliferation, invasion and migration and inhibited the apoptosis of EC cells. The starBase database revealed that linc01194 could bind to insulin-like growth factor 2 binding protein 1 (IGF2BP1). Previous results showed that in EC, IGF2BP1 could promote the expression of sexdetermining region Y-box 2 (SOX2) by promoting the stability of SOX2 mRNA. Our results showed that linc01194 regulate the expression of IGF2BP1 and SOX2. Conclusion Linc01194 can promote the expression of downstream protein SOX2 through binding to IGF2BP1, thus promoting the occurrence and development of EC.
