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.
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 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.
ObjectivesTo systematically review the incidence of various outcomes in non-visualization of the fetal gallbladder (NVFGB) fetuses by prenatal ultrasonography.MethodsPubMed, The Cochrane Library, Elsevier, ClinicalKey, CBM, CNKI and WanFang Data databases were electronically searched to collect studies on NVFGB fetuses by prenatal ultrasonography from January 1990 to March 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by using R 3.5.2 software.ResultsA total of 9 studies were included. The results of meta-analysis showed that: the incidence of fetal biliary atresia was 1.0%, with 2.0% in the isolated and 3.0% in the non-isolated. The incidence of cystic fibrosis was 6.0%, with 2.0% in the isolated and 9.0% in the non-isolated. The incidence of chromosomal abnormality was 5.0%, and 31.0% in non-isolated. The incidence of other malformations other than those described above was 13.0%, with 44.0% in the non-isolated. The incidence of gallbladder agenesis or absent gallbladder was 22.0%, with 28.0% in the isolated. The incidence of later visualization of gallbladder and normal fetal outcomes was 53.0%, with 63.0% in the isolated.ConclusionsCurrent evidence shows that most non-visualization of the fetal gallbladder can identify the presence of gallbladder during late gestation or neonatal ultrasonography. The exactly isolated non-visualization of the fetal gallbladder is highly related to the fetal gallbladder agenesis or the absence of the gallbladder. The non-isolated non-visualization of the fetal gallbladder is highly related to biliary atresia, cystic fibrosis (particularly in the presence of fetal bowel echogenicity), and chromosomal abnormalities (especially chromosome aneuploidy).
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.
Sample size calculation is an important factor to evaluate the reliability of the diagnostic test. In this paper, a case study of the clinical diagnostic test of artificial intelligence for identification of liver contrast-enhanced ultrasound was performed to conduct two-category and multi-categories studies. Based on sensitivity and specificity, the sample size was then estimated in combination with the statistical characteristics of disease incidence, test level and one/two-sided test. Eventually, the sample size was corrected by integrating the factors of the proportion of training/test dataset and the dropout rate of cases in the medical image recognition system. Moreover, the application of Sample Size Calculator, MedCalc, PASS, and other software can accelerate sample size calculation and reduce the amount of labor.
Objective To investigate the relative factors of sleep disorders in patients after arthroscopic knee surgery.MethodsThe clinical data of 155 patients undergoing arthroscopic knee surgery in West China Hospital of Sichuan University from October 1st 2017 to April 1st 2018 were analyzed. The sleep quality index was assessed by the Pittsburgh Sleep Quality Index. According to the scores, the patients were divided into two groups: the sleep disorder group and the non-sleep disorder group. Mindfulness level were evaluated by Mindful Attention Awareness Scale (MAAS). The binary logistic regression was used to assess the relationship between MAAS and sleep disorders.ResultsAmong the enrolled cases, there were 135 males and 20 females, with an average age of (34.12±12.13) years; 64 patients had poor sleep quality. The results of univariate analysis showed that the payment method, single or bilateral lesions, and MAAS score were the factors affecting sleep (P<0.05). The results of multivariate analysis indicated that with medical insurance [odds ratio (OR)=0.118, 95% confidence interval (CI) (0.021, 0.671), P=0.016], postoperative pain [OR=3.379, 95%CI (1.164, 9.812), P=0.025], bilateral lesions [OR=3.842, 95%CI (1.040, 14.191), P=0.044], and MAAS score ≥68 [OR=0.046, 95%CI (0.018, 0.121), P<0.001] were independent predictive factors for sleep disorders (P<0.05). Conclusion Postoperative pain reduction and mindfulness training may improve the patients’ sleep quality and reduce the incidence of sleep disorders.

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 assess the effectiveness of intensive versus routine education on diabetes mellitus for preventing diabetic foot ulcer. Methods We electronically searched CENTRAL (Issue 1, 2013), PubMed (1978-2013), EMbase (1978-2013), VIP (1989-2013) and WanFang Data (1980-2013), hand-searched correlated proceedings and retrieved the references of included studies, for the randomized controlled trials on intensive versus routine education on diabetes mellitus for preventing diabetic foot ulcer all over the world. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results Twelve trials involving 1 841 patients were finally included. The results of meta-analysis showed that: a) the incidence of diabetic foot ulcer in the intensive education group was lower than the routine group, with a significant difference (RR=0.51, 95%CI 0.30 to 0.84, P=0.008); b) two groups were alike in the amputation rate, with no significant difference (OR=0.54, 95%CI 0.17 to 1.67, P=0.28); and c) the score of knowledge on diabetes mellitus was higher in the intensive education group than in the routine education group, with a significant difference (MD=7.32, 95%CI 3.57 to 11.06, P=0.000 1). Conclusion Current evidence shows that: compared with routine education, intensive education could reduce the incidence of diabetic foot ulcer effectively. However, the above conclusion should be verified by conducting more high quality studies.
