Objective To analyze the influencing factors of malaria infection of labor service exported to overseas in Langfang City, in order to establish a visualization tool to assist clinicians in predicting the risk of malaria. Methods A total of 4 774 expatriate employees of the Nibei Pipeline Project of the Pipeline Bureau from October 2021 to August 2023 were taken as the subjects, and the gender, age, overseas residence area and Knowledge of malaria controlscores of the study subjects were investigated by questionnaire survey, and the possible risk factors of malaria were screened by logistic regression model. At the same time, the nomogram prediction model was established, and the subjects were divided into the training group and the validation group at a ratio of 2:1, and the area under the curve (ROC) and the decision curve were plotted to evaluate the prediction ability and practicability of the prediction model in this study. Results Among the 4 774 study subjects, 96 cases of malaria occurred, and the detection rate was 2.01%. Junior school （OR=1.723，95% CI:1.361-2.173）， and residence in rural areas（OR=2.091，95%CI:1.760 -3.100）were risk factors (OR>1), while protective measures（OR=0.826，95% CI : 0.781 - 0.901） and high malaria education scores （OR=0.872，95% CI : 0.621 - 0.899）were protective factors.The nomogram prediction model results showed that the area under the curve of the nomogram prediction model in the training group was 0.94 (95% CI : 0.85 - 1.00), while the validation group was 0.93 (95% CI : 0.80 - 1.00). The results of the decision curve showed that when the threshold probability of the population was 0-0.9, the nomogram model was used to predict the risk of malaria occurrence with the highest net income. Conclusion The nomogram prediction model (including gender, education, region, protection and malaria education score) established and validated in this study is of great value for clinicians to screen high-risk patients with malaria.

Objective To investigate the relationship between serum cyclophilin A(CypA),ischemia modi-fied albumin(IMA),galectin-3(Gal-3)levels and oxidative stress and cognitive impairment(CI)in patients with acute cerebral infarction(ACI)complicated with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods A total of 168 patients with ACI complicated with OSAHS who were admitted to the hospital from December 2020 to October 2023 were selected,and the levels of serum CypA,IMA,Gal-3 and oxidative stress indexes[superoxide dismutase(SOD),malondialdehyde(MDA)]in patients with different severity(mild group,moderate group,severe group)were compared.The correlation between serum CypA,IMA,Gal-3 lev-els and oxidative stress indexes were analyzed by Pearson method.The incidence of CI in patients with ACI complicated with OSAHS were statistically analyzed,the levels of serum CypA,IMA and Gal-3 were com-pared between normal cognitive group and CI group,and the risk factors of CI in patients with ACI complicat-ed with OSAHS were analyzed by multivariate Logistic regression model.Results The levels of serum CypA,IMA,Gal-3 and MDA in mild group,moderate group and severe group increased in turn(P<0.05),and ser-um SOD level decreased in turn(P<0.05).Serum CypA,IMA and Gal-3 in ACI patients complicated with OSAHS were negatively correlated with SOD(P<0.05),and positively correlated with MDA(P<0.05).Of 168 ACI patients complicated with OSAHS,79 cases(47.02%)had CI and were included in the CI group.Compared with normal cognitive group,the serum levels of CypA,IMA and Gal-3 in CI group were signifi-cantly increased(P<0.05).Multivariate Logistic regression model analysis showed that apnea hypopnea in-dex(AHI)≥20 times/h,frontal and temporal lobe infarction,elevated CypA level,elevated IMA level,and el-evated Gal-3 level were risk factors for CI in ACI patients complicated with OSAHS(P<0.05).Conclusion The high expression of serum CypA,IMA and Gal-3 in patients with ACI complicated with OS-AHS is significantly correlated with oxidative stress and CI.The increase of serum CypA,IMA and Gal-3 lev-els indicates an increased risk of CI in patients with ACI complicated with OSAHS,and early detection of the three has good clinical value in evaluating the condition of patients with ACI complicated with OSAHS.

Docynia delavayi (Franch.) Schneid. is an economic fruit plant with high medicinal and edible values. The TCP gene family plays a vital role in plant growth and development. To explore the function of the TCP gene family in the growth and development of D. delavayi. In this study, the TCP gene family (DdeTCP) members were identified from the D. delavayi genome and their expression levels at different stages of seed germination and fruit development were analyzed. The results showed that a total of 18 DdeTCP genes were identified from the D. delavayi genome, with uneven location on 11 chromosomes. The phylogenetic tree showed that the 18 DdeTCPs could be classified into class Ⅱ (3) and class Ⅱ (15), suggesting that functional differentiation occurred among the DdeTCP family members. DdeTCP11 highly homologous to AtTCP14 was highly expressed in the early stage of seed germination, which suggested that this gene played a key role in seed germination. In addition, DdeTCP16 in class Ⅱ had a high expression level during the fruit ripening stage, which indicated that it might be related to fruit ripening. The findings lay a foundation for probing into the roles of the DdeTCP gene family in the growth and development of D. delavayi.

Objective To explore the expression and clinical significance of tissue inhibitor of matrix metal-loproteinases(TIMP)-1 and pentraxin-3(PTX3)in the serum of patients with obstructive sleep apnea-hypop-nea syndrome(OSAHS).Methods A total of 120 patients with OSAHS admitted to the hospital from 2021 to 2022 were selected as the study group,and another 114 healthy people who underwent the physical exami-nation in the same period were selected as the control group.The severity of OSAHS was determined accord-ing to the apnea-hypopnea index(AHI)and the minimum oxygen saturation(LSpO2),and the patients were divided into mild group(66 cases)and the moderate-severe group(54 cases).Serum TIMP-1 and PTX3 levels were measured by enzyme-linked immunosorbent assay.Pearson method was used to analyze the correlation between serum TIMP-1,PTX3 and AHI,LSpO2.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum TIMP-1 and PTX3 on the severity of disease in patients with OSAHS.Logistic regression was used to analyze the factors influencing the severity of the disease in OSAHS patients.Results Serum TIMP-1,PTX3 and AHI levels in the study group were higher than those in the control group,and LSpO2 level was lower than that in the control group(P<0.05).The body mass index(BMI),the proportion of hypertension history,the proportion of coronary heart disease history,the levels of total choles-terol,triglycerides,low-density lipoprotein cholesterol,TIMP-1,PTX3 and AHI in the moderate-severe group were significantly higher than those in the mild group,and the high density lipoprotein cholesterol,LSpO2 lev-el was significantly lower than that in the mild group(P<0.05).Pearson method results showed that serum TIMP-1,PTX3 levels were positively correlated with AHI(r=0.428,0.392,P<0.05),and serum TIMP-1,PTX3 levels were negatively correlated with LSpO2(r=-0.645,-5.836,P<0.05).The results of the ROC curve showed that the area under the curve(AUC)of serum TIMP-1 and PTX3 alone predicted the severity of the patients'disease was 0.813 and 0.777,with cut-off values were 2.47 μg/L and 7.23 ng/L,with the sensi-tivity of 70.37%and 77.78%and the specificity of 77.27%and 72.23%,respectively.The AUC for predic-ting the severity of patients'disease by combining the two was 0.866,which was significantly higher than those of serum TIMP-1(Z=2.067,P=0.039)and PTX3 alone(Z=2.331,P=0.020).Logistic regression a-nalysis showed that TIMP-1,PTX3,history of hypertension,and history of coronary artery disease,AHI and LSpO2 were influential factors for severity of disease in patients with OSAHS(P<0.05).Conclusion TIMP-1 and PTX3 are both up-regulated in the serum of OSAHS patients and closely related to the severity of the disease,and they are the influential factors in the severity of OSAHS patients.

Objective:To investigate the expression of DARS2 and its clinical significance in colorectal cancer.Methods:In this study, bioinformatics tools, especially gene expression profile interactive analysis 2 (GEPIA2), were used to conduct an in-depth analysis of DARS2 expression in colorectal cancer tissues. Immunohistochemical staining was carried out in 108 colorectal cancer specimens and 30 normal colorectal tissues obtained from the First Affiliated Hospital of Nanchang University, Nanchang, China. Colorectal cancer cell lines (HCT116 and SW480) were transfected with small interfering RNA (siRNA) and DARS2 overexpression plasmid to examine the effects of DARS2 knockdown and overexpression on cell function. To assess the effects on cell function, CCK8 and transwell migration assays were used to assess proliferation and cell motility, respectively. Additionally, protein immunoblotting was employed to scrutinize the expression of proteins associated with the epithelial-mesenchymal transition of colorectal cancer cells.Results:DARS2 exhibited a pronounced upregulation in expression within colorectal cancer tissues compared to their normal epithelial counterparts. Furthermore, DARS2 expression was higher in colorectal cancer of stage Ⅲ-Ⅳ than those of stage Ⅰ-Ⅱ, exhibiting a significant correlation with N staging, M staging, and pathological staging ( P<0.05). Kaplan-Meier analyses showed a decreased overall survival rate in colorectal cancer with DARS2 expression compared to those without DARS2 expression ( P<0.05). In the siRNA transfection group, there was a significant reduction in cell proliferation and migration ( P<0.01 and P<0.05, respectively). Conversely, the transfection of DARS2 overexpression plasmids substantially increased both cell proliferation and migration ( P<0.05). Additionally, immunoblotting revealed that DARS2 knockdown led to an upregulation of E-cadherin expression and a downregulation of N-cadherin and vimentin expression. In contrast, DARS2 overexpression resulted in increased N-cadherin and vimentin expression, coupled with reduction in E-cadherin expression. Conclusions:There is a strong association between DARS2 expression and colorectal cancer progression. Silencing DARS2 inhibits cell proliferation and migration, exerting a discernible influence on the epithelial-mesenchymal transition process.

Objective:To explore the application effect of transitional care based on Siebens domain management model in patients with atrial fibrillation.Methods:Using the convenient sampling method, a total of 150 atrial fibrillation patients who were admitted to Nanyang Central Hospital from October 2021 to December 2022 were selected as the research objects. Patients were divided into the study group and the control group using the random number table method, with 75 cases in each group. The control group received routine transitional care, while the study group received transitional care based on the Siebens domain management model. The intervention effect was evaluated using Morisky Medication Adherence Scale and Atrial Fibrillation Self Care Ability Scale.Results:There was no statistically significant difference in scores of Morisky Medication Adherence Scale and Atrial Fibrillation Self Care Ability Scale of patients between the two groups before intervention ( P>0.05). After intervention, scores of Morisky Medication Adherence Scale and Atrial Fibrillation Self Care Ability Scale of patients in the study group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Transitional care based on Siebens domain management model can improve medication adherence and self-care ability of atrial fibrillation patients.

Objective:To understand the current status of existential distress in patients with advanced lung cancer and analyze its influencing factors, so as to provide a reference for developing targeted intervention programs.Methods:A total of 320 patients with advanced lung cancer were selected using convenience sampling from two Class Ⅲ Grade A hospitals in Weifang between February 2022 and August 2023. The data were collected using a General Information Questionnaire, the Chinese Version of the Existential Distress Scale (EDS), the Social Support Revalued Scale (SSRS), the Chinese Version of the Strategies Used by People to Promote Health (SUPPH), and Patient Health Questionnaire-9 (PHQ-9). Spearman correlation analysis was conducted to analyze the relationships between EDS, SSRS, SUPPH, and PHQ-9 scores, and multiple linear regression analysis was used to identify the influencing factors of existential distress in patients with advanced lung cancer. A total of 320 questionnaires were distributed, with 318 valid responses, yielding a valid response rate of 99.38% (318/320) .Results:The total EDS score for the 318 patients was 3.00 (2.00, 4.00). EDS scores were positively correlated with PHQ-9 scores and negatively correlated with SSRS and SUPPH scores ( P<0.01). Multiple linear regression analysis showed that marital status, social support, self-management efficacy, and depression were influencing factors of existential distress in patients with advanced lung cancer ( P<0.05) . Conclusions:Patients with advanced lung cancer experience mild existential distress. Medical staff should assess existential distress levels, paying close attention to patients who are divorced or widowed, have low levels of social support and self-management efficacy, or are experiencing depression. Early interventions should be developed to alleviate negative emotions and help patients rebuild their sense of meaning, thereby improving psychological well-being and reducing survival distress.
