Lung cancer is a malignant tumor with the highest incidence and mortality in China. Early diagnosis and early treatment is the key to improve the survival and prognosis of patients with lung cancer. In recent years, many studies have focused on biomarkers of lung cancer. Emerging biomarkers tests have shown some potential in lung cancer screening. Combining biomarkers, imaging omics and artificial intelligence to establish a comprehensive model for lung cancer screening and prediction may be the development direction for improving lung cancer screening in the future. This paper summarizes the application of biomarkers in lung cancer screening, introduces the emerging biomarkers and new technologies, and discusses the application prospects of biomarkers in lung cancer screening, in order to providea theoretical basis for improving screening, early diagnosis and early treatment of lung cancer.

Objective To study the effect of comprehensive nursing on the treatment compliance and depression of patients with pulmonary tuberculosis complicated with depression. Methods Fifty-seven patients with pulmonary tuberculosis complicated with depression treated between May 2012 and June 2014 were randomly divided into study group (n=30) which was given comprehensive nursing, and control group (n=27) which accepted routine nursing. The scores of depression, treatment compliance and clinical treatment outcome were compared between the two groups. Results The scores of Hamilton Depression Scale were respectively 19.18±2.36, 18.65±2.61, 17.43±1.78 and 16.57±2.05 at the time of 3, 4, 5 and 6 months after nursing intervention, while the same scores of the control group were 22.05±3.03, 21.88±2.85, 20.96±2.06 and 20.04±1.39. The sputum negative conversion rates in the study group at those time periods were respectively 66.7%, 76.7%, 80.0% and 86.7%, while the rates in the control group were 37.0%, 44.4%, 51.6% and 63.0%. The CT lung lesions absorption rates in the study group were 43.3%, 56.7%, 63.3% and 76.7%, while the rates in the control group were 18.5%, 25.9%, 35.3% and 40.7%. The above indicators between the two groups were all statistically significant (P<0.05). The compliance of treatment in the study group was 90.0%, which was significantly higher than that in the control group (63.0%) (P<0.05). Conclusion Comprehensive nursing can help to improve negative emotion, enhance treatment compliance and clinical treatment effect, and promote the early recovery of patients with pulmonary tuberculosis combined with depression.

All patients were treated with irbesartan (150300 mg/d). The variability of circadian blood pressure were observed, and the levels of plasma aldosterone were monitored before and after treatment Results: After the treatment with irbesartan, the blood pressure in all patients were evidently reduced. The night blood pressure of the patient with nondipper essential hypertension had more significant improvement . The circadian variability was appeared. The levels of aldosterone had a significant difference between day and night. Conclusion:Irbesartan has significant effects for the patients with nondipper essential hypertension. It can induce a circadian variability and recover the dipper blood pressure from nondipper blood pressure.
Objective To study the special traits of primiparae’s compliance with labor analgesia, so as to offer individualized analgesia solutions during spontaneous labor. Methods The uniparous primiparae with cephalic presentation between gestational weeks 38 and 40 were divided into two groups based on their educational background (college education or above, and high school education or below), each group with 20 cases. The demographical statistics of the two groups including their State-Trait Anxiety Inventory (STAI) grading, PCA results, and delivery situation were recorded and analyzed. Results Differences in age, height, and weight were not statisticallysignificant (Pgt;0.05); differences in T-AI were not statistically significant (Pgt;0.05); differences in S-AI were statistically significant (Plt;0.05); differences in anxiety and numbers of adding anesthetics were not statistically significant (Pgt;0.05); differences in failure to tolerate labor pains and requiring caesarean section were statistically significant (Plt;0.05). Conclusion Primiparae with higher educational degree tend to have higher S-AI grading and perform poorly in compliance with labor analgesia.
ObjectiveTo systematically review the incidence of financial toxicity among cancer patients in China. MethodsThe Cochrane Library, Web of Science, PubMed, Embase, CINAHL, CNKI, and WanFang databases were searched to collect studies on the prevalence of financial toxicity among cancer patients in China from January 2016 to April 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. A meta-analysis was performed by using Stata 16.0 software. ResultsA total of 24 studies involving 8 799 participants were included. Meta-analysis results showed that the prevalence of financial toxicity among cancer patients was 67.4% (95%CI 60.9% to 74.0%) in China. The subgroup analysis showed that sex, educational level, type of medical insurance, cancer site and stage, the cut-off of the instrument, and region were all influential factors of financial toxicity among cancer patients. ConclusionCurrent evidence shows that high prevalence of financial toxicity among cancer patients. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objectives To assess the efficacy and safety of cytidine diphosphate choline for patients with acute stroke. Methods Such databases as PubMed, The Cochrane Library, EMbase, Web of Science, CNKI, VIP Database and Chinese Medical Association Journals were searched from the establishment to September of 2010, and the references of the included literatures were also searched to collect randomized controlled trials (RCTs) of cytidine diphosphate choline for patients with acute stroke. The data were extracted by two reviewers independently in accordance with the inclusion criteria. The quality of included trials was evaluated according to the Jadad scale standard. RevMan5.0 software was used for data analyses. Results Thirteen RCTs involving 2837 patients were included. The results of meta-analyses showed that, there was no significant difference in the mortality or the rate of dependency at the end of follow-up (OR=0.94, 95%CI 0.66 to 1.36, P=0.75) between the cytidine diphosphate choline group and the placebo group. But the total effective rate of the cytidine diphosphate choline group was higher than that of the placebo group with a significant difference (OR=1.72, 95%CI 1.41 to 2.10, Plt;0.000 01). Five trials reported the incidence of adverse reaction of cytidine diphosphate choline treatment which showed the adverse reaction was mild; no severe adverse events (SAEs) were reported and the clinical application was safe. Conclusion The cytidine diphosphate choline is effective and safe for acute stroke. However, it is invalid to reduce the mortality and the rate of dependency at the end of three months’ follow-up.
Objective To develop and validate a nomogram for predicting the risk of weaning failure in elderly patients with severe pneumonia undergoing mechanical ventilation. Methods A retrospective analysis was conducted on the clinical data of 330 elderly patients with severe pneumonia undergoing mechanical ventilation who were hospitalized in our hospital from July 2021 to July 2023. According to their weaning outcomes, they were divided into a successful group (n=213 ) and a failure group (n=117). Univariate analysis and multivariate non-conditional logistic regression analysis were used to explore the factors influencing the weaning failure of mechanical ventilation in elderly patients with severe pneumonia. Results Univariate analysis showed that there were significant differences in age, smoking status, chronic obstructive pulmonary disease, ventilation time, albumin, D-dimer, and oxygenation index levels between the two groups (all P<0.05). Multivariate logistic regression analysis revealed that age ≥65 years, smoking, presence of chronic obstructive pulmonary disease, ventilation time ≥7 days, D-dimer ≥2 000 μg/L, and reduced oxygenation index were risk factors for weaning failure in the elderly patients with severe pneumonia. The nomogram model constructed based on these factors had an area under ROC curve of 0.970 (95%CI 0.952 - 0.989), and the calibration curve demonstrated good agreement between predicted and observed values. Conclusions Age, smoking status, chronic obstructive pulmonary disease, ventilation time, D-dimer, and oxygenation index are influencing factors for weaning failure in elderly patients with severe pneumonia receiving mechanical ventilation. The nomogram model constructed based on these factors exhibits good discrimination and accuracy.
Family members are crucial for medical disputes. From the psychology and social perspective, the paper analyzes a specific medical dispute case, and discusses the psychological care for (potential) " shidu” (loss of the only child) family. Based on the current social context, an early intervention suggestion is proposed, that is to provide the whole-process psychological intervention to the special patients’ families. The intervention includes: regular psychological evaluation and psychological support if necessary; providing disease knowledge and death education; providing continuous psychological care by the hospital and community; offerring more psychological care for " shidu” family by society.
Objective To evaluate the diagnostic accuracy of Wilson score for predicating difficult intubation. Methods Such databases as PubMed, EMbase, CNKI, WanFang Data and VIP were searched to collect the studies about Wilson score for predicating difficult intubation published from inception to January 2013. Two reviewers independently screened the studies, extracted the data, and assessed the methodological quality by QUADAS. The analysis was conducted by using Meta-Disc 1.4 software, and the random effect model was chosen to calculate the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and the 95%CI. The summary receiver operating characteristic (SROC) curve was drawn and the area under the curve (AUC) was calculated in order to comprehensively assess the total diagnostic accuracy of Wilson score for predicating difficult intubation. Results A total of 9 studies involving 6 506 subjects were included. The results of meta-analysis showed that: the pooled sensitivity was 0.57 (95%CI 0.53 to 0.62), specificity was 0.89 (95%CI 0.88 to 0.90), positive likelihood ratio was 6.11 (95%CI 4.63 to 8.07), negative likelihood ratio was 0.52 (95%CI 0.41 to 0.66), diagnostic odds ratio was 12.76 (95%CI 8.60 to 18.93), and the AUC of SROC was 0.84. Conclusion Wilson score plays a role in predicating difficult intubation, while some other clinical indicators also need to be taken into consideration in its application.
