Objective To investigate the current status of symptom burden and psychological distress among lung cancer patients in the diagnostic phase, and to explore the chain mediating role of social support and resilience between symptom burden and psychological distress. Methods The patients with lung cancer in the diagnostic phase who were treated in the Department of Thoracic Surgery of the Second Xiangya Hospital of Central South University from October 2022 to June 2023 were investigated by a general information questionnaire using the MD Anderson Symptom Inventory, the Social Support Rating Scale, the Connor-Davidson Resilience Scale, and the Distress Thermometer. The chain mediating role of social support and resilience between symptom burden and psychological distress was analyzed. Results A total of 413 lung cancer patients were enrolled, including 173 males and 240 females, aged (54.69±10.82) years. The detection rate of psychological distress among lung cancer patients in the diagnostic phase was 48.18%, and the average score was (3.84±2.50) points. Psychological distress was positively correlated with symptom burden (P<0.01), and negatively correlated with social support and resilience (P<0.01). The mediating effect of resilience between symptom burden and psychological distress was significant. The chain mediating effect of social support and resilience between symptom burden and psychological distress was also significant. Conclusion Lung cancer patients in the diagnostic phase have a high detection rate of psychological distress. Symptom burden can directly impact psychological distress, and can affect psychological distress through the indirect path of resilience as well as the chain mediating path between social support and resilience among lung cancer patients in the diagnostic phase.

Objective: To compare the intervention effects of sitagliptin combined with metformin and insulin aspart combined with metformin among patients with type 2 diabetes mellitus (T2DM), so as to provide the reference for optimizing blood glucose control strategies among patients with T2DM. Methods: T2DM patients admitted to the department of endocrinology of Jinhua Central Hospital from January 2018 to December 2024 were selected as the research objects. According to the propensity score matching, T2DM patients were divided into sitagliptin combined with metformin group and insulin aspart combined with metformin group at a ratio of 1∶1. The basic information, capillary blood glucose, glycosylated hemoglobin blood glucose (HbA1c), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG), body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the two groups were collected by questionnaire survey, physical examination and laboratory test. The generalized estimating equation was used to analyze the changes of various indicators before and after treatment between the two groups of patients, and the intervention effect was compared. Results: There were 69 cases in the sitagliptin combined with metformin group. Among these 42 cases were males, accounting for 60.87%, and 27 cases were females, accounting for 39.13%.Forty-two cases were younger than 60 years, accounting for 60.87%. There were 69 cases in the insulin aspart combined with metformin group. Among these 47 cases were males, accounting for 68.12%, and 22 cases were females, accounting for 31.88%. Forty-five cases were younger than 60 years, accounting for 65.22%. There were no statistically significant differences in gender, age, education level, smoking, drinking, vegetable and fruit intake, and disease duration between the two groups (all P>0.05). After 6 months of treatment, there was an interaction between group and time in capillary blood glucose and HbA1c in the two groups (all P<0.05), and the reduction of capillary blood glucose and HbA1c in the sitagliptin combined with metformin group was greater than that in the insulin aspart combined with metformin group. There were no statistically significant differences between groups and time in TC, HDL-C, TG, BMI, SBP, and DBP, and no interaction effect was found between groups and time (all P>0.05). Conclusion Sitagliptin combined with metformin is more effective than insulin aspart combined with metformin in controlling blood glucose among patients with T2DM.

Objective To investigate the impact of social psychological factors on adherence among subjects with chronic diseases during the early phase of new drug clinical trials and propose strategies to optimize trial outcomes.Methods Between December 2020 to December 2023,observational datas were collected from subjects participating in new drug clinical trials in the Frist Hospital of Jiaxing,including customized sociodemographic informations,Eysenck personality questionnaire(EPQ)survey results,symptom checklist 90(SCL-90)scores,Beck anxiety inventory(BAI)scores,Beck depression inventory(BDI)scores.The SCL-90 was further categorized into ten factor scores,and the EPQ was evaluated based on four dimensional standard T-scores.Univariate and multivariate Logistic regression analyses were conducted to identify the related factors.Results Univariate analyses showed that gender,willingness to go out,EPQ_T neuroticism,SCL-90,SCL somatic,SCL obsessive compulsive,SCL interpersonal,SCL depression,SCL anxiety,SCL psychoticism,SCL other,BAI scores,and BDI scores were associated with adherence in subjects with chronic diseases.Multivariate analysis confirmed that a higher willingness to go out,elevated BAI and BDI scores were positively associated with non-adherence risk,whereas an increase in the SCL-90 somatization factor scores were inversely related to adherence risk in subjects with chronic diseases.Conclusion Identifying and managing anxiety and depression among subjects with chronic diseases,as well as understanding their outdoor plans,are crucial for enhancing adherence during the early stages of new drug clinical trials.In certain instances,subjects with chronic diseases heightened awareness of bodily discomfort may paradoxically promote adherence.

Objective To investigate the expression levels of selenoprotein genes in the patients with coronavirus disease 2019(COVID-19)and the possible regulatory mechanisms.Methods The dataset GSE177477 was obtained from the Gene Expression Omnibus,consisting of a symptomatic group(n=11),an asymptomatic group(n=18),and a healthy control group(n=18).The dataset was preprocessed to screen the differentially expressed genes(DEG)related to COVID-19,and gene ontology functional annotation and Kyoto encyclopedia of genes and genomes enrichment analysis were performed for the DEGs.The protein-protein interaction network of DEGs was established,and multivariate Logistic regression was employed to analyze the effects of selenoprotein genes on the presence/absence of symptoms in the patients with COVID-19.Results Compared with the healthy control,the symptomatic COVID-19 patients presented up-regulated expression of GPX1,GPX4,GPX6,DIO2,TXNRD1,SELENOF,SELENOK,SELENOS,SELENOT,and SELENOW and down-regulated ex-pression of TXNRD2 and SELENON(all P＜0.05).The asymptomatic patients showcased up-regulated expres-sion of GPX2,SELENOI,SELENOO,SELENOS,SELENOT,and SELENOW and down-regulated expression of SELP(all P＜0.05).The results of multivariate Logistic regression analysis showed that the abnormally high expression of GPX1(OR=0.067,95％CI=0.005-0.904,P=0.042)and SELENON(OR=56.663,95％CI=3.114-856.999,P=0.006)was the risk factor for symptomatic COVID-19,and the abnormally high expres-sion of SELP was a risk factor for asymptomatic COVID-19(OR=15.000,95％CI=2.537-88.701,P=0.003).Conclusions Selenoprotein genes with differential expression are involved in the regulation of COVID-19 development.The findings provide a new reference for the prevention and treatment of COVID-19.

Objective:To investigate the safety of tocilizumab (TCZ) in the treatment of children with systemic juvenile idiopathic arthritis (sJIA).Methods:Data of children aged 2 to 18 years with the diagnosis of sJIA and treated with TCZ from June 1, 2017 to June 30, 2022 at our hospital were retrospectively collected. The clinical medication characteristics, incidence, severity and outcome of adverse drug reactions (ADR) were statistically analyzed. Univariate and multivariate analysis were used to analyze the risk factors of TCZ-induced ADR. Univariate comparison between groups were compared to the measured data followed by t test for normal distribution, and the counting data were paired with Chi-square test. Binary logistic regression analysis was used for multivariate analysis. Results:A total of 83 eligible children were enrolled. The age at TCZ initiation was (8.5±3.7) years old. Most of the children received oral glucocorticoid (86.8%) and/or methotrexate (72.3%) prior to TCZ treatment. The mean time of TCZ duration was (1.2±0.9) years, the total TCZ exposure was 92.70 patient years. Fifty-five (66.3%) children reported 123 ADR, with a rate of 132.69/100 patient years. Forty-two (50.6%) children reported 103 general ADR, with a rate of 111.11/100 patient years. Eighteen (21.7%) children reported 20 serious ADR, with a rate of 21.57/100 patient years. The results of univariate analysis showed that the dosage of glucocorticoid in ADR group was higher than that in non-ADR group [(0.76±0.50) mg·kg -1·d -1vs. (0.52±0.41) mg·kg -1·d -1, t=2.27, P=0.026], and the difference was statistically significant. However, there were no significant differences in gender [(male 23, female 32) cases vs. (male 9, female 19) cases, χ2=0.73, P=0.392], age at TCZ initiation [(8.5±3.8) years old vs. (9.0±3.1) years old, t=-0.65, P=0.516], duration of TCZ treatment [(1.24±1.00) years vs. (1.05±0.90) years, t=0.87, P=0.385], methotrexate doses weekly [(8.0±5.2) mg/m 2vs. (7.6±5.1) mg/m 2, t=0.39, P=0.696], and history of drug or food allergy (11 cases vs. 5 cases, χ2=0.06, P=0.815) between the two groups. The results of binary logistic regression analysis showed that the combined use of oral glucocorticoids was an independent risk factor for TCZ-induced ADR [ OR (95% CI) =3.05 (1.11, 8.36), P=0.030]. The risk of ADR was 3.05 times higher in the combined daily dose of glucocorticoids ≥0.76 mg/kg prednisone equivalent than that of < 0.76 mg/kg. Common general ADR to TCZ include infections (38.83/100 patient years) and abnormalities in laboratory parameters (37.76/100 patient years) such as elevated glutamic-pyrupiane transaminase (18.34/100 patient years), dyslipidemia (12.94/100 patient years), and hemocytopenia (5.39/100 patient years). The serious ADR included serious infection (9.71/100 patient years) and serious infusion reaction(7.55/100 patient years). All ADR were improved after drug withdrawal or symptomatic treatment, and no deaths occurred. Conclusion:TCZ has a good safety profile in the treatment of sJIA. Serious infections and severe infusion reactions often lead to discontinuation of the drug. The combination of glucocorticoids≥0.76 mg/kg prednisone equivalent is an independent risk factor for TCZ-induced ADR. Monitoring should be strengthened during the application of TCZ, and ADR should be detected and treated as early as possible to reduce the risk of medication related adverse reactions.

Objective:To explore the role of corticotrophin releasing factor receptor 2 (CRFR2) in regulating pain sensitization and anxiety and its mechanism in chronic migraine mice.Methods:Forty-eight C57BL/6J mice were randomly divided into control group, model group, NBI35965 group and K41498 group ( n=12); chronic migraine models in the later 3 groups were established by intraperitoneally administrating 10 mg/kg nitroglycerin on the 1 st, 3 rd, 5 th, 7 th and 9 th d; mice in the NBI35965 group and K41498 group were injected with 100 nL NBI35965 or K41498 solution into the bilateral trigeminal nucleus caudalis on the 2 nd, 4 th, 6 th and 8 th d, and mice in the control group were injected with same volume of normal saline. Von frey fiber was used to detect the orbitofrontal mechanical pain threshold 2 h after intraperitoneal injection on the 1 st, 3 rd, 5 th, 7 th and 9 th d, and at 11 a.m. on the 10 th d. Elevated plus maze was used to detect the anxiety-like behaviors at 11 a.m. on the 11 th d. Western blotting was performed to detect the protein expressions of corticotrophin releasing factor (CRF), corticotrophin releasing factor receptor 1 (CRFR1), CRFR2 in the trigeminal nucleus caudalis. Real-time quantitative PCR (RT-qPCR) was used to detect the CRFR1 and CRFR2 mRNA expressions in the trigeminal nucleus caudalis. Immunofluorescent staining was used to detect the protein expressions of calcitonin gene-related peptide (CGRP), immediate-early gene c-fos, glial fibrillary acidic protein (GFAP) and ionized calcium-binding adapter molecule 1 (Iba-1) in the trigeminal nucleus caudalis. Results:Compared with the control group, the model group, NBI35965 group and K41498 group had significantly decreased orbitofrontal mechanical pain thresholds 3, 5, 7, 9, and 10 d after intraperitoneal injection ( P<0.05); compared with model group, the K41498 group had significantly increased orbitofrontal mechanical pain thresholds 7, 9, and 10 d after intraperitoneal injection ( P<0.05). Compared with control group, the model group, NBI35965 group and K41498 group had significantly decreased entries and shorter time in opened arms ( P<0.05); compared with the model group, the K41498 group had significantly increased entries and shorter time in opened arms ( P<0.05). Compared with the control group, the model group, NBI35965 group and K41498 group had significantly higher CRF and CRFR2 protein expressions in the trigeminal nucleus caudalis ( P<0.05); compared with the model group, the K41498 group had statistically lower CRF protein expression in the trigeminal nucleus caudalis ( P<0.05). Compared with the control group, the model group, NBI35965 group and K41498 group had significantly higher CRFR2 mRNA expression in the trigeminal nucleus caudalis ( P<0.05). Compard with the control group, the model group, NBI35965 group and K41498 group had significantly increased CGRP, c-fos, Iba-1 and GFAP protein expressions in the trigeminal nucleus caudalis ( P<0.05); compared with the model group, the K41498 group had significantly decreased CGRP and c-fos protein expressions in the trigeminal nucleus caudalis ( P<0.05). Conclusion:CRFR2 can alter the orbitofrontal pain sensitization and anxiety-like behaviors in chronic migraine mice by regulating neuronal activation and CGRP release in the trigeminal nucleus caudalis.

With the optimization of surgical technologies and postoperative management regimens, the number of lung transplantation has been significantly increased, which has become an important treatment for patients with end-stage lung disease. However, due to the impact of comprehensive factors, such as bronchial ischemia and immunosuppression, the incidence of airway stenosis after lung transplantation is relatively high, which severely affects postoperative survival and quality of life of lung transplant recipients. In recent years, with the improvement of perioperative management, organ preservation and surgical technologies, the incidence of airway stenosis after lung transplantation has been declined, but it remains at a high level. Early diagnosis and timely intervention play a significant role in enhancing clinical prognosis of patients with airway stenosis. In this article, the general conditions, diagnosis, treatment and prevention of airway stenosis after lung transplantation were reviewed, aiming to provide reference for comprehensive management of airway stenosis after lung transplantation and improving clinical prognosis of lung transplant recipients.

Objective To analyze the influencing factors of survival of patients with airway stenosis requiring clinical interventions after lung transplantation. Methods Clinical data of 66 patients with airway stenosis requiring clinical interventions after lung transplantation were retrospectively analyzed. Univariate and multivariate Cox’s regression models were adopted to analyze the influencing factors of survival of all patients with airway stenosis and those with early airway stenosis. Kaplan-Meier method was used to calculate the overall survival and delineate the survival curve. Results For 66 patients with airway stenosis, the median airway stenosis-free time was 72 (52,102) d, 27% (18/66) for central airway stenosis and 73% (48/66) for distal airway stenosis. Postoperative mechanical ventilation time [hazard ratio (HR) 1.037, 95% confidence interval (CI) 1.005-1.070, P=0.024] and type of surgery (HR 0.400, 95%CI 0.177-0.903, P=0.027) were correlated with the survival of patients with airway stenosis after lung transplantation. The longer the postoperative mechanical ventilation time, the higher the risk of mortality of the recipients. The overall survival of airway stenosis recipients undergoing bilateral lung transplantation was better than that of their counterparts after single lung transplantation. Subgroup analysis showed that grade 3 primary graft dysfunction (PGD) (HR 4.577, 95%CI 1.439-14.555, P=0.010) and immunosuppressive drugs (HR 0.079, 95%CI 0.022-0.287, P<0.001) were associated with the survival of patients with early airway stenosis after lung transplantation. The overall survival of patients with early airway stenosis after lung transplantation without grade 3 PGD was better compared with that of those with grade 3 PGD. The overall survival of patients with early airway stenosis after lung transplantation treated with tacrolimus was superior to that of their counterparts treated with cyclosporine. Conclusions Long postoperative mechanical ventilation time, single lung transplantation, grade 3 PGD and use of cyclosporine may affect the survival of patients with airway stenosis after lung transplantation.

The survey on the hesitant status of rubella-containing vaccine (RCV) vaccination was conducted among 2 141 women of childbearing age in four provinces, Liaoning, Jiangsu, Zhejiang, and Anhui, from May 2017 to March 2018. Among the 2 141 study participants, a total of 38.21% (818) of women of childbearing age were aware of rubella and 21.25% (455) of women of childbearing age knew about RCV. Among the 455 women of childbearing age who were aware of RCV, 262 (57.58%) were willing to be vaccinated with RCV; 304 women of childbearing age (66.81%) tended to be vaccinated with RCV free of charge. Among the 193 women of childbearing age who did not want to be vaccinated or did not decide whether they preferred to be vaccinated with RCV, no one around them was vaccinated (89, 46.11%) and fear of vaccine safety (70, 36.27%) were the main reasons for hesitation to receive RCV.

Objective:To investigate the relationship between intra-abdominal pressure (IAP) and respiratory function in mechanically ventilated children with severe pneumonia and its prognostic value.Methods:A case-series study.Ninety-two children with severe pneumonia who were treated with mechanical ventilation in the Intensive Care Unit of Children′s Hospital Affiliated to Zhengzhou University from May 2019 to May 2021 were taken as the study subjects.The IAP and respiratory function-related indexes of the children were monitored.Those with IAP ≥12 mmHg(1 mmHg=0.133 kPa) were divided into the study group, and those with IAP <12 mmHg were divided into the control group.The difference in respiratory function related indexes between the 2 groups was compared, and the relationship between IAP and respiratory function indexes was analyzed by Pearson correlation.The children were divided into a good prognosis group and a poor prognosis group according to their prognosis.The relevant clinical data of the children in the 2 groups were collected for univariate analysis, and multivariate Logistic regression was used to analyze the risk factors affecting the prognosis of children with mechanical ventilation for severe pneumonia.A receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of IAP on the prognosis of mechanically ventilated children with severe pneumonia.Results:The arterial partial pressure of oxygen (PaO 2) [(80.15±8.23) mmHg], arterial blood oxygen saturation (SaO 2) [(91.32±2.13)%], and oxygenation index (PaO 2/FiO 2) [(198.29±20.25) mmHg] in the study group were lower than those in the control group [(85.74±8.42) mmHg, (97.05±2.47)%, and (234.84±25.24) mmHg], while the respiratory rate (RR) [(56.23±2.16) breaths/min vs. (50.41±2.24) breaths/min], partial pressure of carbon dioxide (PaCO 2) [(36.48±3.72) mmHg vs.(33.29±3.46) mmHg], fraction of inspired oxygen (FiO 2) [(40.42±4.25)% vs.(36.51±3.72)%], mean arterial pressure (MAP) [(55.98±5.69) mmHg vs.(52.79±5.43) mmHg], and positive end expiratory pressure (PEEP) [(5.03±0.52) cmH 2O vs.(4.52±0.47) cmH 2O, 1 cmH 2O=0.098 kPa] were higher than those in the control group, and the differences were all statistically significant (all P<0.05).The IAP of the children in the study group was (14.25±1.83) mmHg, and that in the control group was (10.38±1.14) mmHg.Pearson correlation analysis showed that IAP was negatively correlated with PaO 2, SaO 2, and PaO 2/FiO 2 ( r=-0.615, -0.587, and -0.647, all P<0.05), and was positively correlated with RR, PaCO 2, FiO 2, MAP, and PEEP ( r=0.618, 0.634, 0.579, 0.578, 0.593, all P<0.05).IAP [(14.76±1.58) mmHg], PaCO 2 [(39.95±4.21) mmHg], FiO 2 [(50.29±5.12)%], alanine aminotransferase[(42.08±4.15) U/L], and total bilirubin [(17.92±1.87) μmol/L] in the poor prognosis group were greater than those [(10.75±1.19) mmHg, (35.37±3.64) mmHg, (45.38±4.47)%, (39.87±4.06) U/L, and (17.09±1.75) μmol/L] in the good prognosis group, while PaO 2 [(65.42±7.86) mmHg vs.(76.42±7.51) mmHg], SaO 2 [(90.65±9.26)% vs.(96.21±2.19)%], and PaO 2/FiO 2 [(130.09±15.15) mmHg vs.(168.40±20.17) mmHg] were smaller than those in the good prognosis group, and the differences were statistically significant (all P<0.05).Logistic regression analysis showed that IAP, PaO 2, PaCO 2, and SaO 2 were risk factors affecting the prognosis of mechanically ventilated children with severe pneumonia (all P<0.05).The optimal cut-off point of IAP for predicting a poor prognosis in mechanically ventilated children with severe pneumonia was 14.55 mmHg, and the area under the ROC curve was 0.873, with a sensitivity of 88.10% and a specificity of 76.00%. Conclusions:IAP has a certain relationship with the respiratory function of mechanically ventilated children with severe pneumonia, and has a good predictive value for the prognosis of the children.
