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.

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.
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).

Methods A total of 126 patients with psoriasis vulgaris treated in our hospital from February 2007 to November 2010 were randomly divided into the treatment group and the control group. Seventy-two patients in the treatment group were treated with NB-UVB radiotherapy combined with compound glycyrrhizin, and 54 patients in the control group were treated with NB-UVB radiotherapy alone. The curative effects were evaluated in terms of the area of injury and therapeutic effect indexes. Results The PASI score after treatment for both groups was obviously lower than before, and the score of the treatment group was significantly lower than the control group after treatment. The efficacy rate was respectively 87.5% and 79.6% for the treatment group and the control group, with a significant difference (Plt;0.05). Conclusion NB-UVB combined with compound glycyrrhizin is safe and effective in treating psoriasis vulgaris, and it is worth popularizing.
Objective To investigate the effects of pain specialist nurse training (PSNT) on nurse’s pain management knowledge and attitude. Methods By distributing the “questionnaire of pain management knowledge and attitude”, 95 certified nurses, who were from 24 hospitals of different levels in Sichuan, Chongqing, Yunnan and Xinjiang, were investigated to survey their knowledge and attitude changes before and after PSNT. The data were analyzed by t-test. Results A total of 190 questionnaires were distributed to 95 nurses, and 190 returned, with a effective response rate of 100%. The result showed that, the total score after training (34.00±5.30) was significantly higher than that before training (17.58±4.00), with a significant difference (P=0.000). Conclusion The pain specialist nurse training can improve nurses’ knowledge and their attitudes on pain management.
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.
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.
