Objective To understand the current status of research on lung cancer immunotherapy to provide a reference for further investigation and future topic selection in this field. Methods CiteSpace visualization analysis software was used to analyze 400 Chinese studies in CNKI and 5 001 English studies in the Web of Science database from 2005 to 2021, with "lung cancer" and "immunotherapy" as keywords. Keyword co-occurrence analysis was performed on 17 English studies of "Lung Cancer" "Immunotherapy" and "Single cell sequencing" in the Web of Science database. Results "Non-small cell lung cancer" "immunosuppressants" "PD-L1" "dendritic cells" and "cytokine-induced killer cells" are current research hotspots in lung cancer immunotherapy. Monoclonal antibody drugs including nivolumab, pembrolizumab, atezolizumab, and durvalumab are hotspot drugs. Immunotherapy combined with chemotherapy as well as PD-L1 expression have become the focus of continuous research. The majority of studies on lung cancer immunotherapy are conducted in the United States, followed by China. Conclusion Lung cancer immunotherapy has gradually become a research hot spot in China. In the future, in-depth research is needed to provide cutting-edge directions for lung cancer immunotherapy.

Objective:To construct the pregnancy risk prediction model of chronic kidney disease (CKD) pregnant women by analyzing their renal function and pregnancy outcome in the first trimester.Method:Totally 313 CKD women with 322 pregnancies who had deliveries in Peking University First Hospital from March 2009 to December 2018 were retrospectively analyzed. The history of kidney disease and renal function in the first trimester were collected, and the relationship between CKD and premature delivery, low birth weight infants, severe preeclampsia and fetal loss were analyzed.Result:Among 322 pregnancies with CKD, 120 (37.3%, 120/322) had adverse pregnancy outcomes. CKD stage, serum creatinine, urea, albumin, hemoglobin, 24-hour urine protein quantity and whether complicated with hypertension were independent predictors of adverse pregnancy outcome. A prediction model logit (P)=2.107+0.255×24-hour urine protein quantitative (g/24-hour)-0.107×albumin (g/L)+1.677×whether complicated with hypertension (1 or 0)+ 0.639×CKD stage was established. The area under curve value of the model was 0.812, the best threshold, sensitivity, specificity and Yoden index were 0.436, 0.658, 0.856 and 0.802, respectively.Conclusion:CKD stage, serum albumin, 24-hour urine protein quantity in the first trimester and hypertension are the main risk factors of adverse pregnancy outcome, which could predict the occurrence of adverse pregnancy outcome of CKD pregnant women and deserve further study.

Objective:To explore the job responsibilities, core competencies, and training certification of information nurses in China.Methods:This study is qualitative research. From January to March 2022, purposive sampling was used to select five information nurses and 9 nursing informatics experts from Zhejiang, Jiangsu, Henan, Fujian, and Taiwan in China for semi-structured in-depth interviews. The Colaizzi analysis method was used to analyze data.Results:After interviews, five themes were identified, namely the job responsibilities of information nurses, the need for information nurses to possess multiple core competencies, the need for unified qualification admission for information nurses, the need for systematic and standardized training methods for information nurses, and the need for qualification certification for information nurses.Conclusions:Nursing managers should focus on cultivating the core competencies of information nurses, including professional knowledge and skills, critical thinking, communication and collaboration abilities, specialized expansion abilities, and nursing management abilities, aiming to improve the professional level of information nurses, which is of great significance for the development of nursing informatics.

Prostate cancer is the most common cancer among men and the fifth leading cause of cancer-related death among men worldwide. Gastrin-releasing peptide receptor (GRPR) is an important complementary target of prostate specific membrane antigen (PSMA) and a key target for prostate cancer diagnosis and treatment. Radionuclide labeled bombesin (BBN) analogues can accurately target overexpressed GRPR in tumor cells, thus providing early diagnosis and treatment of prostate cancer. In this review, we focus on the studies of 99Tc m, 111In, 68Ga, 64Cu, 18F, and 177Lu nuclide-labeled BBN analogues for diagnosis and peptide receptor radionuclide therapy.

Objective:To investigate the personality traits of patients with anxious depression and the relationship between personality traits and clinical symptoms.Methods:From December 2011 to October 2014, 177 first-episode untreated patients with depression from the psychiatric department of the First Affiliated Hospital of Kunming Medical University and 185 healthy controls(HC group) recruited by the community were included.All patients were divided into anxious depression group ( n=92) and non-anxious depression group ( n=85) according to whether the anxiety/somatization factor score ≥7.The simplified version of Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) and the Hamilton depression scale-17 (HAMD-17) were used to assess all the subjects.Statistical analyses were conducted in SPSS 21.0.Analysis of covariance was used to compare the differences of the scores on personality dimensions among the three groups.The relationship between personality dimensions and anxious depression was confirmed by Logistic regression, linear regression analysis and generalized linear models. Results:The differences of the scores on the four dimensions of neuroticism ( F=108.863, P<0.01), extraversion ( F=86.357, P<0.01), agreeableness ( F=50.615, P<0.01), and conscientiousness ( F=24.730, P<0.01) among the three groups were statistically significant.Further pairwise comparision showed, the score of neuroticisms was higher in the anxious depression group(43.05±8.92) and non-anxious depression group(39.85±7.21) than that in the HC group (30.16±6.25)( P<0.01, Bonferroni corrected). The scores of extroversion (31.22±6.33, 32.61±6.83), agreeableness (38.66±5.80, 39.46±6.19) and conscientiousness (39.75±6.89, 38.85±7.26) were lower in the anxious depression group and non-anxious depression group than those in the HC group (40.29±5.37, 44.79±4.68, 44.09±5.66, all P<0.01, Bonferroni corrected). The score of neuroticisms in anxious depression group was higher than that in non-anxious depression group, and the difference was statistically significant ( P<0.01, Bonferroni corrected). Logistic regression analysis with age, gender and years of education controlled showed that the score of neuroticism ( B=0.082, OR=1.085, 95% CI=1.020-1.154, P=0.009) and conscientiousness ( B=0.060, OR=1.062, 95% CI=1.006-1.120, P=0.028) were risk factors for anxiety symptoms in patients with depression.Linear regression analysis showed that the scores on neuroticism had positive predictive effects on the anxiety/somatization factor score ( B=0.055, 95% CI=0.021-0.089, P=0.002) and cognitive impairment factor score ( B=0.074, 95% CI=0.023-0.125, P=0.005) in the anxious depression group. Conclusion:Compared to non-anxious depression, patients with anxious depression show higher level of neuroticism, and the level of neuroticism can positively predict the symptoms of anxiety and cognitive impairment.The high level of neuroticism and conscientiousness may be risk factors for the occurrence of anxiety symptoms in patients with depressed.

OBJECTIVE: To investigate the effects of ALKBH5 on migration, invasion and epithelial-mesenchymal transition (EMT) of human trophoblast cells. METHODS: The expression plasmid of ALKBH5 or a negative control plasmid (ALKBH5-NC) was transfected in human trophoblast HTR-8 /SVneo cells, and the expressions of ALKBH5 mRNA and protein were detected by qRT-PCR and Western blotting. Transwell assay was used to assess the changes in migration and invasion abilities of the trophoblast cells after the transfection. Western blotting was performed to detect the expressions of EMT-related proteins in the cells including vimentin, fibronectin, E-cadherin, N-cadherin, MMP9 and MMP2. RESULTS: ALKBH5 mRNA and protein expressions were significantly higher in ALKBH5 group than in the control group ( CONCLUSIONS ALKBH5 is involved in the pathogenesis of preeclampsia by inhibiting EMT of trophoblast cells and hence reducing their migration and invasion abilities.
