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 investigate the analgesic effect and safety of transincisional quadratus lumborum block(TQLB)technique for laparoscopic nephrectomy.Methods Sixty patients scheduled for laparoscopic nephrectomy at the Affiliated Lihuili Hospital of Ningbo University from December 2023 to March 2024,the patients were randomly divided into TQLB group(T group)and control group(C group)using a random number table method,with 30 cases in each group.C group received general anesthesia with tracheal intubation,while T group received general anesthesia with tracheal intubation combined with TQLB.Two groups of patients were routinely given sufentanil controlled intravenous analgesia pump after surgery.Record the wound healing status of two groups of patients,postoperative 24h sufentanil consumption,resting and exercise time numerical rating scale(NRS)scores at 6h,12h,and 24h postoperatively,range of sensory blockade at 2h postoperatively,number of salvage analgesia cases at 24h postoperatively,analgesic satisfaction score,and incidence of postoperative complications.Results Compared with group C,patients in group T had a reduced consumption of sufentanil 24h after surgery(P＜0.001);The resting and exercise NRS scores decreased at 6h,12h,and 24h after surgery(P＜0.05);The number of postoperative 24h rescue analgesia cases and the satisfaction score of analgesia were both lower than C group(P＜0.05);The incidence of postoperative nausea and vomiting in group T was lower(P＜0.05);Both groups of patients did not experience serious complications.Conclusion TQLB appears to offer effective postoperative analgesia during the early stages of laparoscopic nephrectomy,while also reducing the occurrence of complications.This suggests that it could serve as a safe and efficient alternative for analgesic management in such surgical procedures.

Objective: To compare the clinical efficacy of anterior column reconstruction using single or double titanium mesh cage (TMC) after total en bloc spondylectomy (TES) of thoracic and lumbar spinal tumors. Methods: A retrospective cohort study was performed involving 39 patients with thoracic or lumbar spinal tumors. All patients underwent TES, followed by anterior reconstruction and screw-rod instrumentation via a posterior-only procedure. Twenty-two patients in group A were treated with a single TMC to reconstruct the anterior column, whereas 17 patients in group B were reconstructed with double TMCs. Results: The overall follow-up is 20.5 ± 4.6 months. There is no significant difference between the 2 groups regarding age, sex, body mass index, tumor location, operative time, and intraoperative blood loss. The time for TMC placement was significantly shortened in the double TMCs group (5.2 ± 1.3 minutes vs. 15.6 ± 3.3 minutes, p = 0.004). Additionally, postoperative neural complications were significantly reduced with double TMCs (5/22 vs. 0/17, p = 0.046). The kyphotic Cobb angle and mean intervertebral height were significantly corrected in both groups (p ≤ 0.001), without obvious loss of correction at the last follow-up in either group. The bone fusion rates for single TMC and double TMCs were 77.3% and 76.5%, respectively. Conclusion Using 2 smaller TMCs instead of a single large one eases the placement of TMC by shortening the time and avoiding nerve impingement. Anterior column reconstruction with double TMC is a clinically feasible, and safe alternative following TES for thoracic and lumbar tumors.

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 explore the preventive effect of pneumatic compression therapy combined with infrared irradiation against lower extremity deep vein thrombosis(DVT)in critically ill patients.Methods A total of 150 critically ill patients from January 2021 to January 2023 in the Intensive Care Unit,Quanzhou First Hospital Affiliated to Fujian Medical University were selected and divided into control group and observation group,with 75 cases in each group.The control group patients were treated with conventional rehabilitation measures combined with the boot-type intermittent pneumatic compression therapy device for intermittent inflation and compression therapy,while the observation group patients received the bioinformatic feedback infrared therapy besides the treatment in control group.The incidence of DVT,the average time for swelling and pain reduction,the average time for swelling and pain disappearance,total hospitalization time,the hemodynamic indexes of the lower extremities,coagulation indexes,D-dimer,the recurrence rate of swelling and pain,satisfaction with the rehabilitation,and therapeutic efficacy were recorded.Results After 3 months of discharge,the rate of post-discharge swelling and pain recurrence in observation group was 2.67％(2/75),obviously lower than 10.66％(8/75)in control group(P＜0.05).After 14 days of intervention,the lower extremity deep vein blood flow velocity and peak blood velocity of the two groups increased significantly as compared with those before intervention(P＜0.05),and those were greater in observation group than in control group(P＜0.05).After 14 days of intervention,the coagulation indexes(PT,TT,FIB)and D-dimer level were significantly lower or shorter in both groups as compared with those before intervention(P＜0.05);and observation group had shorter PT and TT,and lower levels of FIB and D-dimer than control group(P＜0.05).The average time for swelling and pain reduction,the average time for swelling and pain disappearance,and the total hospitalization time were shorter and the incidence of DVT was obviously lower in observation group as compared with control group(P＜0.05).The overall response rates of 14-day intervention in observation group vs control group were 97.33％(73/75)vs 88.00％(66/75)(P＜0.05).At the discharge,the satisfaction rates in observation group vs control group were 96.00％vs 85.34％(P＜0.05).Conclusion The combination of bioinformatic feedback infrared therapy and boot-type intermittent pneumatic compression therapy device for intermittent inflation and compression therapy can shorten the average time for swelling and pain reduction,the average time for swelling and pain disappearance and the total hospitalization time,enhance the hemodynamics of the lower extremities,improve the coagulation function and D-dimer level,and improve the satisfaction with the rehabilitation and clinical efficacy,worthy of clinical promotion.

Objective To investigate the effect of Galangin on pyroptosis of bone marrow derived macrophages(BMDMs).Methods BMDMs were cultured in vitro and divided into blank control group,model group and Galangin group with different concentrations.Lipopolysaccharide(LPS)and adenosine triphosphate(ATP)were used to construct the pyroptosis model.The effect of different concentrations of Galangin on the proliferation of BMDMs was detected by cell counting Kit-8(CCK-8).The level of cysteinyl aspartate specific proteinase-1 p10 subunit(caspase-1 p10),interleukin-1β(IL-1β)in supernatant and intracellular nucleotide NOD-like receptor protein 3(NLRP3)were detected by Western blotting.IL-1β in supernatant was detected by enzyme-linked immunosorbent assay(ELISA).The cell death was observed by propidium iodide(PI)staining.High-throughput sequencing was used to compare the gene expression in the model group and Galangin groups at 20 μmol/L.Results There was no statistically significant difference between the 5,10,20,40,60,80 μmol/L Galangin groups on the proliferation level of BMDMs(all P>0.05),indicating that no significant effect of Galangin at 5,10,20,40,60,80 μmol/L was observed on the proliferation of BMDMs.So we selected Galangin at 5,10,20 μmol/L and treatment for 1,2 and 4 hours as the effects of different concentrations and time on the pyroptosis of BMDMs.Compared with blank control group,the expression of caspase-1 p10 and mature IL-1β protein and IL-1β in supernatant in model group were significantly increased(all P<0.05).Compared with model group,the expression of caspase-1 p10 and mature IL-1β protein and IL-1β in supernatant of Galangin at 5,10 and 20 μmol/L were significantly decreased[IL-1β protein expression(gray value):0.155±0.006,0.113±0.006,0.111±0.007 vs.1.000±0.000,caspase-1 p10 protein expression(gray value):0.207±0.044,0.160±0.008,0.082±0.008 vs.1.000±0.000,IL-1β(μg/L):99.80±10.36,85.21±8.78,26.53±4.56 vs.494.10±35.47,all P<0.05].There was no significant difference between the different concentration groups(all P>0.05),but with the extension of treatment time of Galangin,the inhibitory effect was enhanced.The inhibitory effect of Galangin at 20 μmol/L for 4 hours was the most obvious[IL-1β protein expression(gray value):0.186±0.004 vs.1.000±0.000,caspase-1 p10 protein expression(gray value):0.247±0.009 vs.1.000±0.000,IL-1β(μg/L):173.80±10.56 vs.653.80±76.02,all P<0.05].Treatment with 20 μmol/L Galangin for 4 hours could reduce the number of pyroptotic cell deaths(number of view:23.00±3.61 vs.67.67±15.63,P<0.05)and inhibited the expression of NLRP3 protein(gray value:0.178±0.025 vs.0.406±0.066,P<0.05).High-throughput sequencing showed that,compared with the model group,Galangin down-regulated the genes of Nlrp3,Nod2,IL-1β and up-regulated genes of Skp2(also known as Fbxl1),Fbxl20,Fbxl4,Fbxo32 and Fbxw7.Conclusion Galangin inhibited pyroptosis mediated by NLRP3 inflammasome in macrophages.

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 analyze the value of systemic inflammatory indicators in diagnosing schizo-phrenia and their correlation with disease condition severity and cognitive dysfunction.Methods A total of 47 patients with schizophrenia visited and treated in this hospital from October 2021 to March 2023 were selected as the study subjects,and 47 healthy volunteers during the same period served as the control group.The morn-ing fasting venous blood was collected in all research subjects,and the blood routine and biochemical indicators were measured.The SII,SIRI,NHR and LHR were calculated.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of SII,SIRI,NHR and LHR in the patients with schizophrenia.The correlation adopted the Pearson correlation analysis.Results The levels of SII,SIRI,NHR and LHR in the schizophrenia group were significantly increased compared with the control group,and the difference was statistically significant(P＜0.05).The ROC curve analysis demonstrated that the area under the curve(AUC)of SII,SIRI,NHR and LHR detection alone in diagnosing schizophrenia were 0.683,0.686,0.774 and 0.766 respectively.AUC of their combination detection was 0.886.SII was positively correlated with the gen-eral symptoms and the positive and negative symptom scale(PANSS)total score,and negatively correlated with the spatial structure,linguistic function and delayed memory(P＜0.05);SIRI was positively correlated with the negative symptoms,general symptom and PANSS total score,and negatively correlated with the im-mediate memory,spatial structure,linguistic function,attention;NHR was positively correlated with the nega-tive symptoms,positive symptoms,general symptoms and PANSS total score,and negatively correlated with immediate memory,linguistic function,attention and delayed memory(P＜0.05).LHR was positively corre-lated with the positive symptoms,general symptoms and PANSS total score,and negatively correlated with the spatial structure,linguistic function,attention and delayed memory(P＜0.05).Conclusion SII,SIRI,NHR and LHR combined detection has higher diagnostic value for the patients with schizophrenia.Further-more,the SII,SIRI,NHR and LHR levels are closely correlated with the disease condition severity and cogni-tive function impairment degree.

Objective To explore the relationship between the levels of peroxidoredoxin(PRDX)1 and chromosome 10 deletion phosphatase-tensin homologous gene(PTEN)and liver function and disease activity in patients with autoimmune liver disease.Methods A total of 83 patients with autoimmune liver disease ad-mitted to the hospital from January 2021 to December 2022 were selected as the study objects.According to the disease activity at admission,they were divided into active group(37 cases)and remission group(46 ca-ses).Clinical data and serum PRDX1 and PTEN levels of the two groups were analyzed.At the same time,Child-Pugh classification of liver function was performed,and the patients were grouped.A total of 100 health-y volunteers who underwent physical examination during the same period were selected as the control group.Multivariate Logistic regression was used to analyze the influencing factors of disease activity in patients with autoimmune liver disease,and the evaluation value of serum PRDX1 and PTEN levels on disease activity in pa-tients with autoimmune liver disease after treatment was analyzed by receiver operating characteristic(ROC)curve and area under the curve(AUC).Results Compared with the grade A group,there were no significant differences in serum PRDX1 and PTEN levels in the grade B group(P＞0.05),while serum PRDX1 level was increased and PTEN level was decreased in the grade C group(P＜0.05).Compared with the grade B group,the serum PRDX1 level was increased and PTEN level was decreased in the grade C group(P＜0.05).Com-pared with the control group,there were no significant differences in serum PRDX1 and PTEN levels in the re-mission group(P＞0.05),while the serum PRDX1 level was increased and PTEN level was decreased in the active group(P＜0.05).Compared with the remission group,the level of serum PRDX1 was increased and the level of PTEN was decreased in the active group(P＜0.05).The AUC of serum PRDX1 and PTEN for evalu-ating the disease activity in autoimmune liver disease patients was 0.750 and 0.854,respectively,and the AUC of the combined detection of serum PRDX1 and PTEN was 0.916.The proportion of patients with hepatic dis-comfort and cirrhosis in the active stage group was higher than that in the remission stage group(P＜0.05).Multivariate Logistic stepwise regression analysis results showed that hepatic discomfort(OR=3.487,95％CI:1.534-7.927),cirrhosis(OR=4.289,95％CI:1.744-10.545),PRDX1 ≥5.22 ng/mL(OR=5.068,95％CI:1.951-13.164),PTEN≤0.31 pg/mL(OR=5.387,95％CI:2.099-13.829)were risk factors for disease activity of autoimmune liver disease(P＜0.05).Conclusion The increase of serum PRDX1 level and the decrease of serum PTEN level are closely related to liver function and disease activity in patients with au-toimmune liver disease,and they have certain clinical evaluation value in patients with autoimmune liver dis-ease.
